The control device usually does not affect the process being controlled and thus is "add-on" technology, as opposed to a scheme to control pollution through altering the basic process itself. Best Available Control Technology (BACT): An emission limitation based on the maximum degree of reduction of each pollutant subject to regulation under the Clean Air Act emitted from or which results from any major emitting facility, which the permitting authority, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such facility through application of production processes and available methods, systems, and techniques, including fuel cleaning, clean fuels, or treatment or innovative fuel combustion techniques for control of each such pollutant. Best Available Retrofit Control Technology (BARCT): An air emission limitation that applies to existing sources and is based on the maximum degree of reduction achievable, taking into account environmental, energy, and economic impacts by each class or category of source. Case: For a given source category in AirControlNET, if there are more than one control measure for controlling a given pollutant, then each control measure is assigned a case number and is treated as a separate case from the others in the model. Capital Recovery Factor (CRF): A function of the economic life of the equipment and the interest rate charged to the total capital investment. Capital to Annual Ratio: Ratio of Capital costs to annual costs. Cost-Effectiveness (C-E): The cost of an emission control measure assessed in terms of dollars- per-pound, or dollars-per-ton, of air emissions reduced. Control Efficiency: The percent of pollutant mass reduced from the application of a control measure. Control Technique Guidelines (CTGs): An EPA guidance document which triggers a responsibility under section 182(b)(2) for States to submit reasonably available control technology (RACT) rules for stationary sources of VOC as part of their State Implementation Plans. Control Technology; Control Measures: Equipment, processes or actions used to reduce air pollution. The extent of pollution reduction varies among technologies and measures. Criteria Air Pollutant: A pollutant designated by the Administrator, using the latest scientific knowledge, to have effects on public health or welfare which may be expected from the presence of such pollutant in the ambient air, in varying quantities. The types of air pollutants Document No. 05.09.009/9010.463 V Report ------- PECHAN September 2005 which, when present in the atmosphere, may interact with such pollutant to produce an adverse effect on public health or welfare; and any known or anticipated adverse effects on welfare. Cyclone boiler: means a boiler with one or more water-cooled horizontal cylindrical chambers in which coal combustion takes place. The horizontal cylindrical chamber(s) is (are) attached to the bottom of the furnace. One or more cylindrical chambers are arranged either on one furnace wall or on two opposed furnace walls. Gaseous combustion products exiting from the chamber(s) turn 90 degrees to go up through the boiler while coal ash exits the bottom of the boiler as a molten slag. Dry bottom: means the boiler has a furnace bottom temperature below the ash melting point and the bottom ash is removed as a solid. Emission inventory: means a listing of the quantity of pollutants being emitted from sources within a geographic boundary (i.e., country, State, nation). The listing can be broken down into point (individual facilities), area (other stationary sources), mobile (on-road and non-road), and biogenic emissions. Ancillary information such as stack parameters, activity data, and vehicle type are also considered part of an emission inventory. Emission Rate: The weight of a pollutant emitted per unit of time (e.g., tons/year). Federal Implementation Plan (FIP): In the absence of an approved State Implementation Plan (SIP), a plan prepared by EPA which provides measures that nonattainment areas must take to meet the requirements of the Federal Clean Air Act. Inspection and Maintenance Program (I/M program): A periodic automobile inspection, usually done once a year or once every two years to check whether a car is being maintained to keep pollution down and whether emission control systems are working properly. Vehicles which do not pass inspection must be repaired. Lifetime: The estimated years add-on control equipment will operated before it must be replaced. Maximum Achievable Control Technology (MACT): Federal emissions limitations based on the best demonstrated control technology or practices in similar sources to be applied to major sources emitting one or more federal HAP. MEAS Code: An alphanumeric code assigned to each individual control measure in the AirControlNET Model. These are unique and used internally by Pechan. New Source Performance Standards (NSPS): Uniform national EPA air emission standards that limit the amount of pollution allowed from new sources or from modified existing sources. Operating and Maintenance Costs (O&M): The costs associated with work and materials needed to preserve asset components to allow their continued use. This definition encompasses any actions intended to prevent failure or inefficient operation, and includes housekeeping and Document No. 05.09.009/9010.463 vi Report ------- PECHAN September 2005 custodial work. Operating Maintenance does not necessarily prolong the design service life of the property of equipment, nor does it add to the asset's value. However, lack of maintenance can reduce an asset's value by leading to equipment breakdown, premature failure of a building's subsystems and shortening of the asset's useful service lifetime. Reasonably Available Control Technology (RACT): Defined as the lowest emission limitation that a particular source is capable of meeting by the application of control technology that is reasonably available, considering technological and economic feasibility. Rule Effectiveness: a generic term for identifying and estimating the uncertainties in emission estimates caused by failures and uncertainties in emission control programs. Literally, it is the extent to which a rule achieves the desired emission reductions. Source Category: Categories of places or objects from which air pollutants are released. Sources that are fixed in space are stationary sources and sources that move or are capable of moving are mobile sources. See Area, Mobile and Stationary. • Area sources—means stationary and non-road sources that are too numerous or whose emissions are too small to be individually included in a stationary source emissions inventory. • Mobile sources—means on-road (highway) vehicles (e.g., automobiles, trucks and motorcycles) and non-road vehicles and engines (e.g., trains, airplanes, agricultural equipment, industrial equipment, construction vehicles, off-road motorcycles, and marine vessels). • Point Sources: Specific points of origin where pollutants are emitted into the atmosphere from stationary sources such as factory smokestacks. • Stationary Sources: Non-mobile sources such as power plants, refineries, and manufacturing facilities which emit air pollutants. State Implementation Plan (SIP): A plan prepared by States and submitted to EPA describing how each area will attain and maintain national ambient air quality standards. SIPs include the technical foundation for understanding the air quality (e.g. emission inventories and air quality monitoring), control measures and strategies, and enforcement mechanisms. Stoker boiler: means a boiler that burns solid fuel in a bed, on a stationary or moving grate, that is located at the bottom of the furnace. Tangentially fired boiler: means a boiler that has coal and air nozzles mounted in each corner of the furnace where the vertical furnace walls meet. Both pulverized coal and air are directed from the furnace corners along a line tangential to a circle lying in a horizontal plane of the furnace. Transportation Control Measure (TCM): Any control measure to reduce vehicle trips, vehicle use, vehicle miles traveled, vehicle idling, or traffic congestion for the purpose of reducing on- DocumentNo. 05.09.009/9010.463 vii Report ------- PECHAN September 2005 road motor vehicle emissions. TCMs can include encouraging the use of carpools and mass transit. Wall-fired boiler: means a boiler that has pulverized coal burners arranged on the walls of the furnace. The burners have discrete, individual flames that extend perpendicularly into the furnace area. Wet bottom: means that the ash is removed from the furnace in a molten state. The term "wet bottom boiler" shall include: wet bottom wall-fired boilers, including wet bottom turbo-fired boilers; and wet bottom boilers otherwise meeting the definition of vertically fired boilers, including wet bottom arch-fired boilers, wet bottom roof-fired boilers, and wet bottom top-fired boilers. The term "wet bottom boiler" shall exclude cyclone boilers and tangentially fired boilers. Document No. 05.09.009/9010.463 viii Report ------- PECHAN September 2005 CHAPTER I. INTRODUCTION AirControlNET is a control technology analysis tool developed by E.H. Pechan & Associates, Inc. (Pechan) to support the U.S. Environmental Protection Agency (EPA) in its analyses of air pollution policies and regulations. The tool provides data on emission sources, potential pollution control measures and emission reductions, and the costs of implementing those controls. The core of AirControlNET is a relational database system in which control technologies are linked to sources within EPA emissions inventories. The system contains a database of control measure applicability, efficiency, and cost information for reducing the emissions contributing to ambient concentrations of ozone, PM10, PM2 5, S02, N02, as well as visibility impairment (regional haze) from point, area, and mobile sources. PM10 and PM2 5 as included in AirControlNET represent primary emissions of PM. The control measure data file in AirControlNET includes not only the technology's control efficiency, and calculated emission reductions for that source, but also estimates the costs (annual and capital) for application of the control measure. This document describes the control technology and cost information that is used to create the control measure database. The AirControlNET User's Guide and Development Report provide details of the installation, system requirements, use of the AirControlNET interface, and control measure database development (Pechan, 2005a and Pechan, 2005b). AirControlNET relies on the control efficiency, throughput, fuel use, and emission factor data provided in the NEI to perform cost related analysis. But AirControlNET also requires information about individual control measures. This information is obtained by examining the technical and economic data available on the control measures. AirControlNET currently contains information on several hundred different control measure/source combinations. Pechan has collected information on control measure and reported it to the EPA through several technical reports. Important aspects of each control measure, such as application, functionality, cost and control efficiencies were reported at the time of analysis. The purpose of this document is to compile and summarize this information for the control measures presently available in AirControlNET to provide a central location of the information. Individual control measures are discussed in this report under the Control Measure Documentation chapter (Chapter III). Some of the important aspects of analysis used for these control measures are summarized in the Summary section of this report. Table 1-1 provides a list of AirControlNET related publications prepared by Pechan. The References section contains complete citations.

SUMMARY The control measure data needed to generate the costs and emission reductions for measures in AirControlNET include throughput, fuel use, and emission factor data provided in EPA emission inventories such as the National Emissions Inventory (NEI). AirControlNET's database system links control measures to pollution sources identified in EPA point, area, and mobile source emissions inventories. The resulting database of control measures contains information on each measure, including emission reduction, control efficiency, and cost information. Control measures are included for emissions contributing to ambient concentrations of ozone, PM2 5, PM10, S02, and N02, as well as visibility impairment (regional haze). The control measure data in AirControlNET includes not only the measure's control efficiency and calculated emission reduction for that source, but also estimates the costs (annual and capital, and sometimes O&M) for application of the control measure. In determining the costs for each control measure, AirControlNET links basic cost information from EPA and other studies to input parameters contained in the emission inventory. Currently, AirControlNET contains several hundred source category and pollutant-specific control measures. Table II-l provides a summary of the number of control measures that are presently in AirControlNET. Table 11-1.

Important elements that are identified for each control measure. These elements are discussed below and summarized for each measure in the at-a-glance tables in Chapter III of this report. Some of the important factors that have been studied are: Pollutants: AirControlNET contains a database of control measures and cost information for emissions contributing to ambient concentrations of ozone, PM2 5, PM10, S02, and N02, as well as visibility impairment (regional haze). Presently this system includes controls for NOx, S02, VOC, PM10, PM2 5 Hg and NH3. PM10 and PM2 5 as included in AirControlNET represent primary emissions of PM. Sector: AirControlNET relies heavily upon EPA emission inventory data as a source of emissions. The control measures from utility, point, area, and mobile source sector emissions Document No. 05.09.009/9010.463 Report ------- PECHAN September 2005 Sector: AirControlNET relies heavily upon EPA emission inventory data as a source of emissions. The control measures from utility, point, area, and mobile source sector emissions inventories are supplied in EPA's National Emission Inventory (NEI) can be used in creating overall emission reduction scenarios in which the associated costs can be estimated. Control Efficiencies: The control measure data file in AirControlNET includes the technology's control efficiency. The control measure's control efficiency sometimes reflects a set of baseline conditions that are elaborated upon in the at-a-glance tables in Chapter III of the report, where appropriate. Cost Information: The cost information in AirControlNET may have many components including annual, capital, and operation & maintenance costs for application of the control measure. The individual control measure reference documents discuss the source of the cost information. Other components include capital recovery factor and dollar year of cost estimate (i.e., SI997). Base Year of Cost: The cost information for the control measures have been compiled through a series of analyses performed by EPA and others over several years. In every case, the costs for control measure is estimated in the base year provided by the original study. AirControlNET converts to consistent year dollars. POD: The cost POD is an internal field which groups together similar source types. We can think of them as a group of sources similar enough that a specific control measure can be applied to all SCCs in the group. Affected SCC: The Source Classification Code, or the SCC, in combination with the POD are what link the control measure information to the NEI data. This linkage is essential for AirControlNET functions which allow the user to create various cost related scenarios based on the selected control measures applied to specific sources of emission. Rule Effectiveness: Rule effectiveness is the assumption of how effective a rule containing a control measure would be. Rule effectiveness is generally 80 to 100 percent for point source rules and potentially less for area source or mobile source rules. Rule Penetration: Rule Penetration is the assumed fraction of the targeted SCC which are affected by the control measure. It is generally assumed 100 percent for point sources, but can be less for area or mobile sources. Measure Code: The control measures codes are unique codes assigned by E.H. Pechan & Associates that specify control measure and source type combination. Each measure in Chapter III of this report is identified by an alphanumeric measure code or a "meas code". The first character of the code is a letter that corresponds to the major pollutant controlled. Typical Value: The typical value often referred to in this report is the value used in AirControlNET. The value has been determined to be the "best" value for a measure of interest Document No. 05.09.009/9010.463 II-2 Report ------- PECHAN September 2005 (e.g. control efficiency). The typical value can be, but is not necessarily, a statistical measure of central tendency. Table II-2 provides a list of the control measures and sources documented in this report.

The control applies to all cattle and calve operations classified under SCC 280503000. Affected SCC: 2805020000 Cattle and Calves Composite, Total Pollutant(s) PM10 PM2.5 EC OC NOx VOC S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 50% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: Pechan contacted the manufacturer of the chemical inhibitor, N-(n-butyl) thiophosphoric triamide (NBPT; trade name Conserve-Nr). According to the manufacturer, the control effectiveness at cattle feedlots is 50 percent and the cost per head-day is $0.0062 ($2.26/head-yr; Axe, 1999). The manufacturer also reports that field tests are ongoing at dairies and that the product should perform the same (50 percent control), but cost slightly more $0.0094/head-day ($3.43/head-yr; Axe, 1999). It was not clear why the costs would be higher at dairies. To estimate costs, an average per head cost between dairy cattle and feedlot cattle would be $2.85/head-yr (from the above estimates). The emission factor for cattle is about 23 kg/head-yr (0.025 ton/head-yr). A 50 percent control efficiency yields 0.0125 ton/head-yr reduced). Hence, the cost factor would be $2.85/0.0125 ton or $228/ton of NH3 reduced. Cost Effectiveness: The cost effectiveness is $228 per ton HN3 reduced.

Assessment of control measures applicable to ammonia emissions for hog operations is based on procedures used for cattle operations. The control applies to all hog and pig operations classified under SCC 2805025000. Affected SCC: 2805025000 Hogs and Pigs Composite, Total Pollutant(s) PM10 PM2.5 EC OC NOx VOC S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 50% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: Pechan contacted the manufacturer of the chemical inhibitor, N-(n-butyl) thiophosphoric triamide (NBPT; trade name Conserve-Nr). According to the manufacturer, the control effectiveness at cattle feedlots is 50 percent and the cost per head-day is $0.0062 ($2.26/head-yr; Axe, 1999). According to the manufacturer, the same 50 percent control efficiency derived for cattle can be assumed for hogs (Axe, 1999). The emission factor for hogs is 20.3 Ib/head-yr. With the 50 percent control efficiency, this equates to 10.15 Ib/head-yr reduced (5.08 x 10-3 ton/head-yr reduced). Therefore, the cost parameter would be $0.37/5.08E-3 ton or $73/ton NH3 reduced. Cost Effectiveness: The cost effectiveness used in AirControlNET is $73 per ton NH3 reduced. (1999$) Comments: Status: Demonstrated Last Reviewed: 1999 Additional Information: There is assumed to be 100 percent penetration; however, the modeling parameters are probably most applicable to large hog farming operations. Hence, it may be more reasonable to apply the control in counties with large hog raising operations (i.e., using COA data). References: Axe, 1999: D.

Document No. 05.09.009/9010.463 III-12 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Source Category: Poultry Operations Control Measure Name: Chemical Additives to Waste Rule Name: Not Applicable Pechan Measure Code: A00201 POD: 02 Application: This control is the chemical addition of alum to poultry litter. Alum is used to stabilize poultry litter to reduce ammonia emissions. Alum, an acid-forming compounds, keeps the pH of the poultry litter below 7, which inhibits ammonia volatilization. The control applies to all poultry and chicken operations classified under SCC 280503000. Affected SCC: 2805030000 Poultry and Chickens Composite, Total Pollutant(s) PM10 PM2.5 EC OC NOx VOC S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 75% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: Treatment costs are estimated to be about $0.025/head (Moore, 1999). These costs do not factor in some benefits to the grower (e.g., reduced heating/ventilation costs due to lower ammonia levels; higher value for fertilizer due to higher nitrogen levels). Assuming six grow-outs per year, the costs would be $0.15/head-yr. The emission factor used for all poultry is 0.394 Ib/head-yr (1.97 x 10-4 ton/head-yr). Assuming a 75 percent control efficiency for alum treatment, the emission reduction would be 1.48 x 10-4 ton/head-yr reduced. Hence, the cost parameter would be $0.15/1.48E-04 ton reduced or $1,014/ton NH3 reduced. Cost Effectiveness: The cost effectiveness used in AirControlNET is $1,014 per ton NH3 reduced. (1999$) Comments: Status: Demonstrated Last Reviewed: 1999 Additional Information: The control effectiveness for alum treatment is estimated to be 75 percent (Moore, 1999). The control effectiveness is highest during the early part of the growing cycle (i.e., >95 percent), when the young chickens are most susceptible to health problems from high ammonia levels. The control effectiveness drops off during the grow-out (about two months). Alum is then reapplied to the litter before the next grow-out begins (typically, there are 5 or 6 grow-outs per year). There is assumed to be 100 percent penetration. Document No. 05.09.009/9010.463 III-13 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES References: Axe, 1999: D.

Ozone season daily ban of agricultural burning to reduce NOx emissions during the ban. This control is applicable to field burning where the entire field would be set on fire, and can be applied to all crop types. These sources are classified under 2801500000. Affected SCC: 2801500000 Agricultural Burning Pollutant(s) PM10 PM2.5 EC OC NOx voc S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: Daily control efficiency is 100% from uncontrolled; Annual control efficiency is 0% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 80% Penetration: 100% Cost Basis: Since burning can simply be shifted to other acceptable periods, emission control costs are assumed to be zero for regulations that schedule the burning days where ozone exceedances are not predicted (Pechan, 1997). Cost Effectiveness: The cost effectiveness used in AirControlNET is $0 per ton NOx reduced (1990$). Note: Since this is a daily control, no annual emission reductions are expected. Comments: Status: Demonstrated Last Reviewed: 1997 Additional Information: Costs may be incurred if personnel scheduled to participate in the agricultural burning cannot be used elsewhere or if fire personnel or other professionals have been scheduled to participate. Assuming full compliance with the regulation, ozone season daily emission reductions from such a regulation would be 100 percent. However, annual emission reductions would not be expected, because there would likely be a shift in the timing of the emissions, not a reduction in the total amount of annual NOx emitted. A compliance rate of 80 percent is used in estimating daily reductions (Pechan, 1997).

LNBs reduce the amount of NOx created from reaction between fuel nitrogen and oxygen by lowering the temperature of one combustion zone and reducing the amount of oxygen available in another. This control is applicable to small (<1 ton NOx per OSD) ammonia production operations with natural gas-fired reformers (SCC 30100306) and uncontrolled NOx emissions greater than 10 tons per year.

Small source = emissions level less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned along with a capital to annual costs ratio of 5.5. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 70% (Pechan, 2001). Cost Effectiveness: The cost effectiveness used in AirControlNET is $820 per ton NOx reduced from both uncontrolled and RACT (1990$).

Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Small source = emissions level less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). The basis of the costs are model plant data for mechanical draft heaters firing natural gas and oil contained in the Alternative Control Techniques (ACT) document (EPA, 1993). From this analysis, default cost per ton values are assigned along with a capital to annual costs ratio of 5.9. An equipment life of 10 years is assumed (EPA, 1993). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 70% (Pechan, 2001).

Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 111-23 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures. This control applies to small (<1 ton NOx per OSD) wet-process cement manufacturing (SCC 30500706) with uncontrolled NOx emissions greater than 10 tons per year.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 15 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than 70% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the detailed information in the EC/R report Tables 6-3, 6-13 and 6-14. The breakdown was obtained using the average costs for furnaces having capacities of 113 and 180 MMBTU per hour. A capacity factor of 0.913 is used in estimating the O&M cost breakdown.

Document No. 05.09.009/9010.463 111-53 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

According to this analysis, the capital needed for making the required modifications to the boilers and adding the required sensors, software and control devices was estimated to be $250,000 per unit. The annual operating and maintenance costs for the control systems were estimated to be $40,000 per boiler. This analysis, however does not take into account the projected energy savings. Wisconsin Department of Natural Resources estimated the costs associated with three government-owned facilities in 2000 and estimated the initial expenditure for the boilers to be approximately $100,000 each. Including expected fuel savings, the Wisconsin Department of Natural Resources estimated an annualized net savings of $50,000 per year for each unit (WDNR, 2000). All costs are in 1999 dollars. Cost Effectiveness: The cost analysis is based on the 2000 Wisconsin SIP which estimated the cost effectiveness of the NOx combustion optimization to range from a cost savings of $100 to a cost of $50 per ton NOx reduced (1999$). The average Document No. 05.09.009/9010.463 111-60 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES value used in AirControlNET is a cost of $50 per ton NOx reduced. The analysis includes projected energy savings from thermal efficiency improvements for units that utilize combustion optimization (WDNR, 2000). All costs are in $1999. Comments: Status: Demonstrated Last Reviewed: 2003 Additional Information: In coal-fired plants it is estimated that thermal efficiency can be improved by 0.5%. The improved heat rate from the units that utilize combustion optimization translates into further pollution prevention, in addition to the reduced NOx emissions (EPA, 2002). All combustion processes require a mixture of fuel and air. Improper fuel to air ratio can result in thermal inefficiencies and/or excessive emissions from the boilers. Combustion optimization measures seek to find and maintain optimum combustion conditions by applying better controls on the air and fuel injection mechanisms of the boilers. One approach used in process optimization utilizes a neural network computer program to find the optimum control points. For example, advanced controls, such as furnace sensors and coal flow measuring devices, can be used to optimize the boiler combustion by controlling the flow of fuel and air into the boiler (EPA, 1999). Combustion must be optimized for the conditions that are encountered and often requires customized designs for individual boilers. For example, when boiler tubes are far enough away from the burner, computer controls from some vendors are designed to decrease the amount of air that is pre-mixed with fuel from the stoichiometric ratio to lengthen the flame at the burner and reduce the rate of heat release per unit volume (EPA, 1999).

O&M Cost Components: There are no O&M costs associated with dry low NOx combustors. Cost Effectiveness: When capacity is available and within the applicable range of 0 to 2,000 MMBTU/hr the cost equations are used to calculate cost effectiveness. The default cost effectiveness value, used when capacity information is not available, is $100 per ton NOx reduced from uncontrolled and $140 per ton NOx reduced from RACT (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

This analysis found that a rule based on an emission limit of 40 nanograms per joule (ng/j) of heat output for natural gas heaters with a heat input rating less than 75,000 Btu/hr would not result in an increase in the cost of natural gas water heaters. The cost-effectiveness of NOx reductions resulting from low-NOx residential water heaters is, therefore, zero dollar- per-ton of NOx removed. It is assumed that the technology for residential water and space heaters can be transferred to commercial installation at a similar cost to achieve the same percentage reduction (Pechan, 1997). Cost Effectiveness: The cost effectiveness used in AirControlNET is $0 per ton NOx reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 1997 Additional Information: EPA (1995) noted a life expectancy of both conventional and low-NOx units ranging from 10 to 15 years.

The cost savings is based on capital costs associated with installation of energy efficient equipment existing demand-side management programs, energy savings, associated emission reductions, and the prevailing emission credit price (SCAQMD, 1996). Costs for the space heaters are based on the low-NOx limits established for the South Coast and Bay Area Air Quality Management Districts for space heaters of 0.009 lbs NOx per million Btu. The cost effectiveness estimate for the low-NOx space heater regulation is $1,600 per ton NOx (STAPPA/ALAPCO, 1994). For this analysis a 75% reduction in commercial space heater NOx emissions is assumed, based on a 20-year equipment life (Pechan, 1997). The water heater savings and LNB space heater costs are combined to achieve an overall cost effectiveness of $1,230 per ton NOx reduced.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-116 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Comments: Status: Demonstrated Last Reviewed: 1998 Additional Information: The 500 tons per day plant is assumed to be representative of flat glass plants (Pechan, 1998). LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

From this analysis, default cost per ton values are assigned. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than 70% (Pechan, 2001).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature Document No. 05.09.009/9010.463 III-126 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Comments: Status: Demonstrated Last Reviewed: 1998 Additional Information: The 500 tons per day plant is assumed to be representative of flat glass plants (Pechan, 1998). LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Small source = emission levels less than 1 ton per ozone season day Large source = emission levels greater than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than 70% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated by applying percentages of O&M breakdown for SNCR as applied to process heaters, using detailed information found in Table 6-3 and Chapter 6 of the Process Heater ACT document. The breakdown was obtained using the O&M costs for a 50 ton per day furnace.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip..

Therefore, all heavy duty diesel vehicles were assumed to employ selective catalytic reduction as a retrofit technology through the voluntary diesel retrofit program. The average cost of a selective catalytic reduction system ranges from $10,000 to $20,000 per vehicle depending on the size of the engine, the sales volume, and other factors (Pechan, 2003). For this AirControlNET analysis, the average estimated cost of this system is $15,000 per heavy duty diesel vehicle. Selective catalytic reduction requires the use of low sulfur diesel fuel. The costs for the low sulfur diesel fuel were applied to all gallons of diesel fuel used by the heavy duty diesel vehicles. Low sulfur diesel fuel is estimated to cost an additional $0.05 per gallon of diesel (EPA, 2000). All costs are in 1999 dollars. Cost Effectiveness: The cost effectiveness of selective catalytic reduction varies greatly by county and depends mostly on the number of vehicles. Cost effectiveness for NOX fell within the following range: $13,499 to $56,474 per ton NOx reduced. The average cost effectiveness used in AirControlNET is $50,441.54 per ton NOX reduced.

Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-173 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Small source = emissions level less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned along with a capital to annual costs ratio of 2.0. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 20 years (EPA, 1994).

O&M Cost Components: The O&M cost component breakdown is estimated using the material in Appendix B - 4.0 Cyclone-Fired boilers for coal reburning of the Cadmus report (1995). Cost breakdowns were provided in this Group 2 boiler analysis for 150 MW and 400 MW cyclone boilers. A capacity factor of 0.65 is used in estimating the O&M cost breakdown.

SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures. This control applies to small (<1 ton NOx per OSD) coal/cyclone ICI boilers with uncontrolled NOx emissions greater than 10 tons per year.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values and a capital to annual cost ratio of 7.0 are assigned.

In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 70% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the Chapter 4 costing algorithms in EPA, 2001. The fixed O&M cost is the sum of the annual maintenance material and labor cost, and is estimated to be 0.66 percent of the capital cost. This portion of the O&M cost is included in the database as maintenance labor. The NH3 use cost equation is used to estimate chemicals costs. The annual replacement cost equation is used to estimate replacement materials costs. The energy requirement cost equation is used to estimate electricity costs. Electricity cost = $0.03/kW-hr Document No. 05.09.009/9010.463 III-186 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Ammonia cost = $225/ton The above O&M component costs are in 2000 dollars. The model plant size used to estimate ICI boiler O&M cost components is 400 MMBtu/hr. Cost Effectiveness: The default cost effectiveness value is $820 per ton NOx reduced from both uncontrolled and RACT baselines (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

NGR is a combustion control technology in which part of the main fuel heat input is diverted to locations above the main burners, called the reburn zone. As flue gas passes through the reburn zone, a portion of the NOx formed in the main combustion zone is reduced by hydrocarbon radicals and converted to molecular nitrogen (N2). This control applies to small (<1 ton NOx per OSD) coal/cyclone ICI boilers with uncontrolled NOx emissions greater than 10 tons per year.

Small source = less than 1 ton NOx per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). The basis of the costs are model plant data in the Alternative Control Techniques (ACT) document (EPA, 1994). From this analysis, default cost per ton values are assigned along with a capital to annual costs ratio of 2.0. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 20 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 70% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the economic analysis for a 200 megawatt unit provided in Appendix E: Cost Analysis of Reburning Systems for conventional gas reburn. The example calculation with a $1.00 per million Btu difference between the primary fuel cost and the reburn fuel cost was used. The reference for this information is the 1998 Andover Technology Partners report for NESCAUM/MARAMA. The fuel cost differential is the dominant operating cost of NGR.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In a reburn boiler, fuel is injected into the upper furnace region to convert the NOx formed in the primary combustion zone to molecular N2 and H20. In general, the overall process occurs within three zones of the boiler; the combustion zone, the gas reburning zone, and the burnout zone (ERG, 2000). In the combustion zone the amount of fuel is reduced and the burners may be operated at the lowest excess air level. In the gas reburning zone the fuel not used in the combustion zone is injected to create a fuel-rich region where radicals can react with NOx to form molecular Nitrogen. In the burnout zone a separate overfire air system redirects air from the primary combustion zone to ensure complete combustion of unreacted fuel leaving the reburning zone. Operational parameters that affect the performance of reburn include reburn zone stoichiometry, residence time in the reburn zone, reburn fuel carrier gas and temperature and 02 levels in the burnout zone (ERG, 2000).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

O&M Cost Components: The O&M cost breakdown is estimated using the Chapter 4 costing algorithms in EPA, 2001. The fixed O&M cost is the sum of the annual maintenance material and labor cost, and is estimated to be 0.66 percent of the capital cost. This portion of the O&M cost is included in the database as maintenance labor. The NH3 use cost equation is used to estimate chemicals costs. The annual replacement cost equation is used to estimate replacement materials costs. The energy requirement cost equation is used to estimate electricity costs. Electricity cost = $0.03/kW-hr Ammonia cost = $225/ton The above O&M component costs are in 2000 dollars. The model plant size used to estimate ICI boiler O&M cost components is 400 MMBtu/hr.

The default cost effectiveness values, used when capacity information is not available, are $1,070 per ton NOx reduced from uncontrolled and $700 per ton NOx reduced from RACT (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Document No. 05.09.009/9010.463 III-208 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Small source = emissions level less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned along with a capital to annual costs ratio of 4.5. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 70% (Pechan, 2001).

The model boiler size used to develop O&M cost components is 766 MMBtu/hr. A capacity factor of 0.58 is used in estimating the O&M cost breakdown. Electricity cost: $0.05/kW-hr Cost Effectiveness: The default cost effectiveness value used in AirControlNET is $1,460 per ton NOx reduced from both uncontrolled and RACT (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Document No. 05.09.009/9010.463 III-215 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Cost Effectiveness: The default cost effectiveness value is $1,260 per ton NOx reduced from both uncontrolled and RACT baselines (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Document No. 05.09.009/9010.463 III-227 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

O&M Cost Components: The O&M cost breakdown is estimated using the information in the appendix to the 1994 ICI Boiler ACT document. The only O&M cost for LNBs is for administrative, property tax, and insurance, and these are estimated (in total) as 4 percent of the capital investment cost.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

SNCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). This control applies to small (<1 ton NOx emissions per OSD) natural gas-fired IC boilers with uncontrolled NOx emissions greater than 10 tons per year.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned for small sources. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 20 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 70% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the example problem in the OAQPS Control Cost Manual chapter on SNCR. This example was for a 1,000 MMBtu/hr boiler burning sub-bituminous coal.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

The following equations, based primarily on information in the Air Pollution Cost Manual (EPA, 2002), are used for large NOx sources as defined above: From Uncontrolled: Document No. 05.09.009/9010.463 III-285 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Capital Cost = 62,148.8 * Capacity (MMBtu/hr)A0.423 Annual Cost = 2,012.4 * Capacity (MMBtu/hr)A0.7229 From RACT Baseline: Capital Cost = 48,002.6 * Capacity (MMBtu/hr)A0.423 Annual Cost = 5,244.4 * Capacity (MMBtu/hr)A0.4238 Note: All costs are in 1990 dollars. O&M Cost Components: The O&M cost breakdown is estimated using the example problem in the OAQPS Control Cost Manual chapter on SNCR. This example was for a 1,000 MMBtu/hr boiler burning sub-bituminous coal. Electricity cost: $0.05/kW-hr Coal cost: $1.60/MMBtu Cost Effectiveness: When capacity is available and within the applicable range of 0 to 2,000 MMBTU/hr the cost equations are used to calculate cost effectiveness. The default cost effectiveness value, used when capacity information is not available, is $1,050 per ton NOx reduced from uncontrolled and $560 per ton NOx reduced from RACT (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Document No. 05.09.009/9010.463 III-286 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

SNCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). This control applies to small (<1 ton NOx emissions per OSD) wood/bark fired IC boilers with uncontrolled NOx emissions greater than 10 tons per year.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned for small sources. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 20 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 70% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the example problem in the OAQPS Control Cost Manual chapter on SNCR. This example was for a 1,000 MMBtu/hr boiler burning sub-bituminous coal.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned for small sources. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 20 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than 70% (Pechan, 2001). Cost Effectiveness: The cost effectiveness used in AirControlNET for both reductions from baseline and reductions from RACT is $1,260 per ton NOx reduced (1990$).

This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 15 years (EPA, 1993). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 25% (Pechan, 2001). Cost Effectiveness: The cost effectiveness value (for both small and large sources) used in AirControlNET is $2,340 per ton NOx reduced from both uncontrolled and RACT baselines (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-343 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

SNCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). This control applies to iron and steel mill annealing operations with uncontrolled NOx emissions greater than 10 tons per year, classified under SCC 30300934.

Small source = emission levels less than 1 ton per ozone season day Large source = emission levels greater than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned for small sources. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than 55% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated by applying percentages of O&M breakdown for SCR as applied to process heaters, using detailed information found in Table 6-3 and Chapter 6 of the Process Heater ACT document. The breakdown was obtained using the average O&M costs for 3 annealing furnaces having capacities of 100, 200 and 300 MMBTU per hour. Electricity: $0.06 per kw-hr Fuel (nat gas): $2.00 per MMBTU Ammonia: $0,125 per lb Document No. 05.09.009/9010.463 III-349 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Cost Effectiveness: The cost effectiveness (for both small and large sources) used in AirControlNET for both reductions from baseline and reductions from RACT is $1,640 per ton NOx reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

LNBs reduce the amount of NOx created from reaction between fuel nitrogen and oxygen by lowering the temperature of one combustion zone and reducing the amount of oxygen available in another. SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures.

The basis of the costs are model plant data in the Alternative Control Techniques (ACT) document (EPA, 1994). From this analysis, default cost per ton values are assigned along with a capital to annual costs ratio of 3.7. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than 55% (Pechan, 2001). Cost Effectiveness: The default cost effectiveness values are $1,720 per ton NOx reduced from uncontrolled and $1,320 per ton NOx reduced from RACT (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-352 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNB's create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNB's create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002). Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

A capital cost to annual cost ratio of 3.8 was developed to estimate default capital and operating and maintenance costs. From these determinations, default cost effectiveness values were assigned. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1994). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies greater than 15% and less than or equal to 25% (Pechan, 2001). Cost Effectiveness: The default cost effectiveness value is $1,320 per ton NOx reduced from both uncontrolled RACT baselines (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Low excess air works by reducing levels of excess air to the combustor, usually by adjustments to air registers and/or fuel injection positions, or through control of overfire air dampers. The lower oxygen concentration in the burner zone reduces conversion of the fuel nitrogen to NOx. Also, under excess air conditions in the flame zone, a greater portion of fuel-bound nitrogen is converted to N2 therefore reducing the formation of fuel NOx (ERG, 2000).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Document No. 05.09.009/9010.463 III-382 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Document No. 05.09.009/9010.463 III-395 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Source Category: Nitric Acid Manufacturing - Small Sources Control Measure Name: Non-Selective Catalytic Reduction (NSCR) Rule Name: Not Applicable Pechan Measure Code: N0293S, N029036 POD: 29 Application: This control is the reduction of NOx emission through selective non-catalytic reduction add-on controls. SNCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). This control applies to nitric acid manufacturing operations with uncontrolled NOx emissions greater than 10 tons per year. These sources are classified under SCCs 30101301 and 30101302. Affected SCC: 30101301 Chemical Manufacturing, Nitric Acid, Absorber Tail Gas (Pre-1970 Facilities) 30101302 Chemical Manufacturing, Nitric Acid, Absorber Tail Gas (Post-1970 Facilities) Pollutant(s) PM10 PM2.5 EC OC NOx voc S02 NH3 CO Hg V* X V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 98% from uncontrolled Equipment Life: 10 years Rule Effectiveness: 100% Penetration: 100% Cost Basis: Sources are distinguished by NOx emission levels (Pechan, 1998). Small source = emission levels less than 1 ton per ozone season day Large source = emission levels greater than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned for small sources. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 10 years (EPA, 1991). O&M Cost Components: The O&M cost breakdown is estimated using the detailed information in Table 6-4 and Ch. 6 of the Nitric and Adipic Acid Manufacturing Plant ACT document. The breakdown was obtained using O&M costs for three plants having capacities of 200, 500 and 1000 tons per day. Maintenance materials and labor: 4% of capital cost Operating labor - direct: $22 per hour Operating labor - supervision: 20% of direct operating labor Fuel (natural gas): $4.12 per MMBTU Cost Effectiveness: The cost effectiveness (for both small and large sources) used in Document No. 05.09.009/9010.463 III-396 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES AirControlNET for both reductions from baseline and reductions from RACT is $550 per ton NOx reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

This measure would not reduce the annual emissions. Affected SCC: 2610000000 Open Burning 2610010000 Open Burning 2610020000 Open Burning 2610030000 Open Burning Pollutant(s) PM10 PM2.5 EC OC NOx voc S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: Daily control efficiency is 100% from uncontrolled; Annual control efficiency is 0% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 80% Penetration: 100% Cost Basis: Because burning can simply be shifted to other acceptable periods, emission control costs would be zero for regulations that shift the burning to days where ozone exceedances are not predicted (Pechan, 1996). Although this periodic ban would have no cost in the stationary source measures, a cost may be incurred in the area source total due to labor shifts. Cost Effectiveness: The cost effectiveness associated with this control is $0 per ton NOx reduced. (1990) Note: Since this is a daily control, no annual emission reductions are expected. Comments: Status: Demonstrated Last Reviewed: 1996 Additional Information: Generally, the relatively low temperatures associated with open burning tend to suppress NOx emissions. Because of the relatively low level of NOx emissions expected to result from open burning, little attention has been paid to quantifying or controlling the NOx emissions from this source. However, some jurisdictions control open burning by limiting the types of material that can be burned, or, based on ambient conditions limiting the days on which materials can be burned. Assuming full compliance with the regulation, daily NOx emission reductions from such a regulation would be 100% (Pechan, 1996). However, annual emission reductions would not be expected because there would likely be a shift in the timing of emissions, not a reduction in the total amount of Document No. 05.09.009/9010.463 III-414 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES annual NOx emitted.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned for small sources. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 15 years (EPA, 1993). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 48% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the detailed information in Table 6-4 and Ch. 6 of the Process Heaters ACT. The breakdown was obtained using the O&M costs for a mechanical draft process heater fired on distillate oil and having a capacity of 69 MMBTU per hour. The cost percentage is applied to heaters fired on LPG via technology transfer (Pechan, 1998). A capacity factor of 0.58 is used in estimating the O&M cost breakdown.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Document No. 05.09.009/9010.463 III-467 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

LNBs reduce the amount of NOx created from reaction between fuel nitrogen and oxygen by lowering the temperature of one combustion zone and reducing the amount of oxygen available in another. SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures. This control is applicable to small (40 to 174 MMBtu/hr) natural gas-fired process heaters with uncontrolled NOx emissions greater than 10 tons per year.

In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 55% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the detailed information in Table 6-3 and Ch. 6 of the ACT for Process Heaters. The breakdown was obtained using the O&M costs for a mechanical draft process heater having a capacity of 77 MMBTU per hour. A capacity factor of 0.5 is used in estimating the O&M cost breakdown. Electricity: $0.06 per kw-hr Fuel (natural gas): $2.00 per MMBTU Ammonia: $0,125 per lb Cost Effectiveness: The default cost effectiveness values are $11,560 per ton NOx reduced from uncontrolled and $27,910 per ton NOx reduced from RACT (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNB's create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNB's create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002). Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a Document No. 05.09.009/9010.463 III-470 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNB's create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNB's create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002). SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 15 years (EPA, 1993). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies greater than 26% and less than or equal to 55% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the detailed information in Table 6-4 and Ch. 6 of the Process Heaters ACT. The breakdown was obtained using the O&M costs for a mechanical draft process heater fired on residual fuel oil and having a capacity of 69 MMBTU per hour. The cost percentage is applied to heaters fired on other fuel via technology transfer (Pechan, 1998). A capacity factor of 0.58 is used in estimating the O&M cost breakdown.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

LNBs reduce the amount of NOx created from reaction between fuel nitrogen and oxygen by lowering the temperature of one combustion zone and reducing the amount of oxygen available in another. SCR controls are post- combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20).

Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures.

Small source = emission levels less than 1 ton per ozone season day Costs for stationary source NOx control are based on an analysis of EPA's NOx State Implementation Plan (SIP) Call (Pechan, 1998). From this analysis, default cost per ton values are assigned. A discount rate of 7 percent and a capacity factor of 65 percent are assumed, along with an equipment life of 15 years (EPA, 1993). In general, the incremental default cost is used for sources where there are existing controls (RACT baseline), with efficiencies less than or equal to 55% (Pechan, 2001). O&M Cost Components: The O&M cost breakdown is estimated using the detailed information in Table 6-3 and Ch. 6 of the Process Heaters ACT. The breakdown was obtained using the O&M costs for a mechanical draft process heater fired on natural gas and having a capacity of 77 MMBTU per hour. The cost percentage is applied to heaters fired on process gas via technology transfer (Pechan, 1998). A capacity factor of 0.5 is used in estimating the O&M cost breakdown.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

Staged-fuel LNB's create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002). SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

New water heaters would be required to emit less than or equal to 40 ng NOx per Joule heat output. This control applies to all natural gas burning water heaters classified under SCC 2104006000. Affected SCC: 2104006000 Natural Gas, Total: All Combustor Types Pollutant(s) PM10 PM2.5 EC OC NOx voc S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 7% from uncontrolled Equipment Life: 13 years Rule Effectiveness: 100% Penetration: 23% Cost Basis: In 1994, EPA conducted an analysis of the emission reductions and costs for a Federal Implementation Plan residential water heater rule for the Sacramento, California ozone nonattainment area (EPA, 1995). This analysis found that a rule based on an emission limit of 40 nanograms per joule (ng/j) of heat output for natural gas heaters with a heat input rating less than 75,000 Btu/hr would not result in an increase in the cost of natural gas water heaters. The cost-effectiveness of NOx reductions resulting from low-NOx residential water heaters is, therefore, zero dollar- per-ton of NOx removed. Cost Effectiveness: The cost effectiveness used in AirControlNET is $0 per ton NOx reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 1997 Additional Information: EPA (1995) noted a life expectancy of both conventional and low-NOx units ranging from 10 to 15 years. Thus, rule penetration is based on an average water heater equipment life of 13 years (Pechan, 1996).

This control is based on the installation of low-NOx space heaters and water heaters in commercial and institutional sources for the reduction of NOx emissions. The control applies to natural gas burning sources classified under SCC 2104006000.

The cost savings is based on capital costs associated with installation of energy efficient equipment existing demand-side management programs, energy savings, associated emission reductions, and the prevailing emission credit price (SCAQMD, 1996). Costs for the space heaters are based on the low-NOx limits established for the South Coast and Bay Area Air Quality Management Districts for space heaters of 0.009 lbs NOx per million Btu. The cost effectiveness estimate for the low-NOx space heater regulation is $1,600 per ton NOx (STAPPA/ALAPCO, 1994). For this analysis a 75% reduction in commercial space heater NOx emissions is assumed, based on a 20-year equipment life (Pechan, 1997). The water heater savings and LNB space heater costs are combined to achieve an overall cost effectiveness of $1,230 per ton NOx reduced. Cost Effectiveness: The cost effectiveness is $1,230 per ton NOx reduced (1990$).

Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-540 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-546 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-556 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-572 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Selective Catalytic Reduction (SCR) has been widely applied to stationary source, fossil fuel-fired, combustion units for emission control since the early 1970s. SCR is typically implemented on units requiring a higher level of NOx control than achievable by SNCR or other combustion controls (EPA, 2002). Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. The use of a catalyst results in two advantages of the SCR process over SNCR, the higher NOx reduction efficiency and the lower and broader temperature ranges. However, the decrease in reaction temperature and increase in efficiency is accompanied by a significant increase in capital and operating costs (EPA, 2002). The cost increase is due to the large amount of catalyst required. The SCR system can utilize either aqueous or anhydrous ammonia as the reagent. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Today, catalyst formulations include single component, multi-component, or active phase with a support structure. Most catalyst formulations contain additional compounds or sup-ports, providing thermal and structural stability or to increase surface area (EPA, 2002). The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: reaction temperature range; residence time available in the optimum temperature range; degree of mixing between the injected reagent and the combustion gases; uncontrolled NOx concentration level; molar ratio of injected reagent to uncontrolled NOx; ammonia slip; catalyst activity; catalyst selectivity; pressure drop across the catalyst; catalyst pitch; catalyst deactivation; and catalyst management (EPA, 2001).

This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002). Ammonia can be utilized in either aqueous or anhydrous form. Anhydrous ammonia is a gas at atmospheric pressure and normal temperatures. There are safety issues with the use of anhydrous ammonia, as it must be transported and stored under pressure (EPA, 2002). Aqueous ammonia is generally transported and stored at a concentration of 29.4% ammonia in water. Urea based systems have several advantages, including several safety aspects. Urea is a nontoxic, less volatile liquid that can be stored and handled more safely than ammonia. Urea solution droplets can penetrate farther into the flue gas when injected into the boiler, enhancing mixing (EPA, 2002). Because of these advantages, urea is more commonly used than ammonia in large boiler applications. The rate of reaction determines the amount of NOx removed from the flue gas. The important design and operational factors that affect the rate of reduction include: Reaction temperature range; Residence time available in the optimum temperature range; Degree of mixing between the injected reagent and the combustion gases Uncontrolled NOx concentration level; Molar ratio of injected reagent to uncontrolled NOx ; and Ammonia slip.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In a reburn boiler, fuel is injected into the upper furnace region to convert the NOx formed in the primary combustion zone to molecular N2 and H20. In general, the overall process occurs within three zones of the boiler; the combustion zone, the gas reburning zone, and the burnout zone (ERG, 2000). In the combustion zone the amount of fuel is reduced and the burners may be operated at the lowest excess air level. In the gas reburning zone the fuel not used in the combustion zone is injected to create a fuel-rich region where radicals can react with NOx to form molecular Nitrogen. In the burnout zone a separate overfire air system redirects air from the primary combustion zone to ensure complete combustion of unreacted fuel leaving the reburning zone. Operational parameters that affect the performance of reburn include reburn zone stoichiometry, residence time in the reburn zone, reburn fuel carrier gas and temperature and 02 levels in the burnout zone (ERG, 2000).

The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx. Selective Catalytic Reduction (SCR) systems are among the post-combustion NOx control systems that can be effective in controlling mercury. This is based on recent pilot-scale tests that indicate that SNCR and SCR systems may enhance Hg capture under some conditions by oxidizing HgO (Massachusetts, 2002). Researches are investigating the possibility of HgO to Hg2+ conversion in SCR systems as a possible result of ammonia on fly ash mercury reactions. In the SCR process, a catalyst (such as vanadium, titanium, platinum, or zeolite) is used in a bed reactor, and the NOx reduction occurs at the surface of the catalyst bed with the help of a reducing agent (diluted ammonia or urea, which generates ammonia in the process). The ammonia mixture is injected into the flue gas upstream of the metal catalyst bed reactor, which is located upstream of a PM or S02 control device (usually Document No. 05.09.009/9010.463 III-583 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES between the economizer outlet and air heater inlet, where temperatures range from 230 to 400oC). Recent pilot-scale tests indicate that SCR systems can enhance Hg capture under some conditions by oxidizing HgO. On the plant-size scale, only one set of tests have been performed to measure the effectiveness of SCR systems. Application of SCR system, combined with spray dryer absorber was tested at a plant which was firing bituminous coal. The test results indicated greater than 95 percent mercury removal for the combined co-control systems (Massachusetts, 2002).

This increase results in a reduction in boiler efficiency, requiring more coal to be burned to maintain the boiler output. As the coal firing rate increases, there are corresponding increases in the solid waste generation and auxiliary power usage. The O&M costs were evaluated for tangential-fired boilers only. With no changes in the capital cost for wall-fired boilers, the fixed O&M costs, generally taken as a function of the capital cost, are not expected to vary. Also, no changes in the variable O&M costs are expected, since unburned carbon assumptions are unchanged. For tangential-fired boilers, the general maintenance cost was conservatively taken as 1.5 percent of the total project cost for each technology. Also, a plant capacity factor of 85 percent was assumed. Coal Cost: $1.20/MMBtu Solid waste disposal: $12/ton Auxiliary power: 25 mills/KWh Note: All costs are in 1999 dollars. Cost Effectiveness: Cost effectiveness is variable and based on plant size (nameplate capacity in MW) and the following factors: the total capital cost of $9.1 per kW; the fixed O&M costs of $0.14 per kW per year; and variable O&M costs of $0.0 mills per kW per year (1999$). Comments: Status: Demonstrated Last Reviewed: 2005 Additional Information: LNBs are designed to "stage" combustion so that two combustion zones are created, one fuel-rich combustion and one at a lower temperature. Staging techniques are usually used by LNB to supply excess air to cool the combustion process or to reduce available oxygen in the flame zone. Staged- air LNBs create a fuel-rich reducing primary combustion zone and a fuel-lean secondary combustion zone. Staged-fuel LNBs create a lean combustion zone that is relatively cool due to the presence of excess air, which acts as a heat sink to lower combustion temperatures (EPA, 2002).

The example problem in subsection 1.5 is used as an example for computing typical capital and annual costs of a retrofit SNCR system being applied to a 1,000 MMBtu/hour wall-fired, industrial boiler firing sub-bituminous coal. In this analysis, the SNCR system is assumed to operate for 5 months of the year with a capacity factor of 65 percent, resulting in a total capacity factor of 27 percent. The total variable direct annual cost is the sum of the cost of the reagent, electricity, water, coal, and ash. Indirect annual costs are zero. Electricity Cost: $0.05 $/kW-hr Coal Cost: $1.60/MMBtu Note: All costs are in 1990 dollars. Cost Effectiveness: Cost effectiveness is variable and based on plant size (nameplate capacity in MW) and the following factors: the total capital cost of $15.80 per kW; the fixed O&M costs of $0.24 per kW per year; and variable O&M costs of $0.73 mills per kW per year (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002).

NGR is a combustion control technology in which part of the main fuel heat input is diverted to locations above the main burners, called the reburn zone. As flue gas passes through the reburn zone, a portion of the NOx formed in the main combustion zone is reduced by hydrocarbon radicals and converted to molecular nitrogen (N2). This control applies to pulverized-dry bottom coal-fired electricity generation sources.

In the IPM, model plants applying NGR had capacities of 200 MW. The equations were scaled to develop costs for smaller or larger boilers than the model plant. The cost equations also assume a high NOx rate (>=0.5 pounds per MMBtu), a 7% discount rate, and a 20-year lifetime of the controls.

The example calculation with a $1.00 per million Btu difference between the primary fuel cost and the reburn fuel cost was used. The reference for this information is the 1998 Andover Technology Partners report for NESCAUM/MARAMA. The fuel cost differential is the dominant operating cost of NGR. Coal Cost: $ 1.50/MM Btu Natural Gas Cost: $2.50/MMBtu Note: All costs are in 1990 dollars. Cost Effectiveness: Cost effectiveness is variable and based on plant size (nameplate capacity in MW) and the following factors: the total capital cost of $26.90 per kW, the fixed O&M of $0.41 per kW per year, and the variable O&M of $0 per kW-hr (1990$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In a reburn boiler, fuel is injected into the upper furnace region to convert the NOx formed in the primary combustion zone to molecular N2 and H20. In general, the overall process occurs within three zones of the boiler; the combustion zone, the gas reburning zone, and the burnout zone (ERG, 2000). In the combustion zone the amount of fuel is reduced and the burners may be operated at the lowest excess air level. In the gas reburning zone the fuel not used in the combustion zone is injected to create a fuel-rich region where radicals can react with NOx to form molecular Nitrogen. In the burnout zone a separate overfire air system redirects air from the primary combustion zone to ensure complete combustion of unreacted fuel leaving the reburning zone. Operational parameters that affect the performance of reburn include reburn zone stoichiometry, residence time in the reburn zone, reburn fuel carrier gas and temperature and 02 levels in the burnout zone (ERG, 2000).

SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) with a nitrogen based reducing reagent, such as ammonia or urea, to reduce the NOx into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures.

The fixed O&M cost is the sum of the annual maintenance material and labor cost, and is estimated to be 0.66 percent of the capital cost. This portion of the O&M cost is included in the database as maintenance labor. The NH3 use cost equation is used to estimate chemicals costs. The annual replacement cost equation is used to estimate replacement materials costs. The energy requirement cost equation is used to estimate electricity costs. Electricity cost = $0.03/kWhr Ammonia cost = $225/ton The above O&M component costs are in 2000 dollars. The model plant size used to estimate utility boiler O&M cost components is 750 MMBtu/hour. Note: All costs are in 1999 dollars. Cost Effectiveness: Cost effectiveness is variable and based on plant size (nameplate capacity in MW) and the following factors: the total capital cost of $100 per kW; the fixed O&M cost of $0.66 per kW per year; and the variable O&M cost of $0.6 mills per KW-hr (1999$). Comments: Status: Demonstrated Last Reviewed: 2005 Additional Information: Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx.

SNCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) with a nitrogen based reducing reagent, such as ammonia or urea, to reduce the NOx into molecular nitrogen (N2) and water vapor (H20) This control applies to bituminous/subbituminous coal-fired electricity generation sources with cyclone furnaces.

In the IPM, model plants applying SNCR had capacities of 100 MW. The equations were scaled to develop costs for smaller or larger boilers than the model plant. The cost equations also assume a high NOx rate (>=0.5 pounds per MMBtu) and a capacity utilization factor of 65% were assumed for the utility boilers, as well as a 7% discount rate and 20-year lifetime of the controls.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: SNCR is the reduction of NOx in flue gas to N2 and water vapor. This reduction is done with a nitrogen based reducing reagent, such as ammonia or urea. The reagent can react with a number of flue gas components. However, the NOx reduction reaction is favored for a specific temperature range and in the presence of oxygen (EPA, 2002). Both ammonia and urea are used as reagents. The cost of the reagent represents a large part of the annual costs of an SNCR system. Ammonia is generally less expensive than urea. However, the choice of reagent is also based on physical properties and operational considerations (EPA, 2002).

NGR is a combustion control technology in which part of the main fuel heat input is diverted to locations above the main burners, called the reburn zone. As flue gas passes through the reburn zone, a portion of the NOx formed in the main combustion zone is reduced by hydrocarbon radicals and converted to molecular nitrogen (N2). This control applies to pulverized-dry bottom coal-fired electricity generation sources with cyclone furnaces. Applies to bituminous/subbituminous coal-fired electricity generation sources with cyclone furnaces.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In a reburn boiler, fuel is injected into the upper furnace region to convert the NOx formed in the primary combustion zone to molecular N2 and H20. In general, the overall process occurs within three zones of the boiler; the combustion zone, the gas reburning zone, and the burnout zone (ERG, 2000). In the combustion zone the amount of fuel is reduced and the burners may be operated at the lowest excess air level. In the gas reburning zone the fuel not used in the combustion zone is injected to create a fuel-rich region where radicals can react with NOx to form molecular Nitrogen. In the burnout zone a separate overfire air system redirects air from the primary combustion zone to ensure complete combustion of unreacted fuel leaving the reburning zone. Operational parameters that affect the performance of reburn include reburn zone stoichiometry, residence time in the reburn zone, reburn fuel carrier gas and temperature and 02 levels in the burnout zone (ERG, 2000).

SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) with a nitrogen based reducing reagent, such as ammonia or urea, to reduce the NOx into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures.

The fixed O&M cost is the sum of the annual maintenance material and labor cost, and is estimated to be 0.66 percent of the capital cost. This portion of the O&M cost is included in the database as maintenance labor. The NH3 use cost equation is used to estimate chemicals costs. The annual replacement cost equation is used to estimate replacement materials costs. The energy requirement cost equation is used to estimate electricity costs. Electricity cost = $0.03/kWhr Ammonia cost = $225/ton The above O&M component costs are in 2000 dollars. The model plant size used to estimate utility boiler O&M cost components is 750 MMBtu/hour. Note: All costs are in 1999 dollars. Cost Effectiveness: Cost effectiveness is variable and based on plant size (nameplate capacity in MW) and the following factors: the total capital cost of $80 per kW; the fixed O&M cost of $0.53 per kW per year; and the variable O&M cost of $0.37 mills per KW-hr (1999$). Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx.

NGR is a combustion control technology in which part of the main fuel heat input is diverted to locations above the main burners, called the reburn zone. As flue gas passes through the reburn zone, a portion of the NOx formed in the main combustion zone is reduced by hydrocarbon radicals and converted to molecular nitrogen (N2). This control applies to large (>100 million Btu/hr) natural-gas fired electricity generation sources, excluding tangentially fired sources.

In the IPM, model plants applying NGR had capacities of 200 MW. The equations were scaled to develop costs for smaller or larger boilers than the model plant. The cost equations also assume a high NOx rate (>=0.5 pounds per MMBtu) and a capacity utilization factor of 65% were assumed for the utility boilers, as well as a 7% discount rate and 20-year lifetime of the controls.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In a reburn boiler, fuel is injected into the upper furnace region to convert the NOx formed in the primary combustion zone to molecular N2 and H20. In general, the overall process occurs within three zones of the boiler; the combustion zone, the gas reburning zone, and the burnout zone (ERG, 2000). In the combustion zone the amount of fuel is reduced and the burners may be operated at the lowest excess air level. In the gas reburning zone the fuel not used in the combustion zone is injected to create a fuel-rich region where radicals can react with NOx to form molecular Nitrogen. In the burnout zone a separate overfire air system redirects air from the primary combustion zone to ensure complete combustion of unreacted fuel leaving the reburning zone. Operational parameters that affect the performance of reburn include reburn zone stoichiometry, residence time in the reburn zone, reburn fuel carrier gas and temperature and 02 levels in the burnout zone (ERG, 2000).

SCR controls are post-combustion control technologies based on the chemical reduction of nitrogen oxides (NOx) with a nitrogen based reducing reagent, such as ammonia or urea, to reduce the NOx into molecular nitrogen (N2) and water vapor (H20). The SCR utilizes a catalyst to increase the NOx removal efficiency, which allows the process to occur at lower temperatures. Applies to large (>100 million Btu/hr) natural-gas fired electricity generation sources, excluding tangentially fired sources.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Like SNCR, SCR is based on the chemical reduction of the NOx molecule. The primary difference between SNCR and SCR is that SCR uses a metal-based catalyst to increase the rate of reaction (EPA, 2002). A nitrogen based reducing reagent, such as ammonia or urea, is injected into the flue gas. The reagent reacts selectively with the flue gas NOx within a specific temperature range and in the presence of the catalyst and oxygen to reduce the NOx.

Propane flamers are an alternative to open filed burning. The bale/stack burning technique is designed to increase the fire efficiency by stacking or baling the fuel before burning. Burning in piles or stacks tends to foster more complete combustion, thereby reducing PM emissions. This control is applicable to field burning where the entire field would be set on fire, and can be applied to all crop types. These sources are classified under 2801500000. Affected SCC: 2801500000 Agricultural Field Burning - whole field set on fire, Total, all crop types Pollutant(s) PM10 PM2.5 EC oc NOx VOC S02 NH3 CO Hg V* V V V V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: PM10 control efficiency is 49-63% from uncontrolled; PM2.5 control efficiency is 25% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: The cost of using a propane burner includes the cost for physical removal of residue, and the costs for operating the flamer, which vary with the speed of operation. The average cost of propane burning is $56 per acre, which includes the cost for residue removal and for the propane flaming (Pechan, 1998). The costs for baling and burning average $25 per ton of residue baled and $0.50 per ton to burn, or approximately $25.50 per ton of residue burned (EPA, 1992). Capital costs for both of these techniques are assumed to be zero. Costs vary by state and crop type. The cost effectiveness ranges from $1,832 for Georgia to $8,164 for Florida The PM10 control efficiency ranges from 49% for Louisiana to 63% for Alabama, Georgia, Kansas, Mississippi, and North Carolina. Note: All costs are in 1992 dollars. Cost Effectiveness: The cost effectiveness per ton PM10 reduced is $2,591.

Soil conservation plans could include: establishment of rows of vegetation across the prevailing wind, cessation of tilling on high-wind days, establishment of snow (sand) fences, establishment of end-of-row turn-around areas, deep furrowing of fallow parcels, prohibition of disking and improved tillage practices.

This estimate was derived from cost estimates developed for stabilization of fallow fields, which along with the cessation of tilling on high-wind days, is considered to be the most likely control included in the soil conservation plans (SCAQMD, 1996). No capital expenditures have been identified, as most of the potential control actions include a change in agricultural methods using equipment already possessed by farm owners/operators. Conversion to 1990 dollars was done using the U.S. Department of Agriculture's index for prices paid for farm services/operations (Pechan, 1997). Cost Effectiveness: The cost effectiveness is $138 per ton PM10 reduced (1990$).

When stack gas flow rate data was Document No. 05.09.009/9010.463 III-635 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. Document No. 05.09.009/9010.463 III-636 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Document No. 05.09.009/9010.463 III-637 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars.

The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Costs are primarily driven by the waste stream volumetric flow rate and pollutant loading. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. Document No. 05.09.009/9010.463 III-643 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $7 to $13 per scfm Typical value is $9 per scfm O&M Costs: Range from $9 to $25 per scfm Typical value is $14 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average cartridge cost was estimated using the costs for standard cartridge types. Capital recovery for the periodic replacement of cartridges was included in the O&M cost of the cartridges using a cartridge life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $85 to $256 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $142 per ton PM10 reduced. (1998$) Comments: Document No. 05.09.009/9010.463 111-644 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Status: Demonstrated Last Reviewed: 2001 Additional Information: Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions. Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). The cost estimates assume a conventional design under typical operating conditions. Auxiliary equipment, such as fans and ductwork, is not included (EPA, 2000). Pollutants that require an unusually high level of control or that require the filter media or the unit itself to be constructed of special materials, such as Nomex ® or stainless steel, will increase the costs of the system (EPA, 1998a). The additional costs for controlling more complex waste streams are not reflected in the estimates given below. For these types of systems, the capital cost could increase by as much as 75% and the O&M cost could increase by as much as 10%. In general, a small unit controlling a low pollutant loading will not be as cost effective as a large unit controlling a high pollutant loading (EPA, 2000). Cartridge filters contain either a paper or nonwoven fibrous filter media (EPA, 2000). Paper media is generally made of materials such as cellulose and fiberglass. The dust cake that forms on the filter media from the collected PM can significantly increase collection efficiency (EPA, 1998b). In general, the filter media is pleated to provide a larger surface area to volume flow rate. Close pleating, however, can cause PM to bridge the pleat bottom, effectively reducing the surface collection area (EPA, 1998b). Corrugated aluminum separators are used to prevent the pleats from collapsing (Heumann, 1997). There are variety of cartridge designs and dimensions. Typical designs include flat panels, V-shaped packs or cylindrical packs (Heumann, 1997). For certain applications, two cartridges may be placed in series. Cartridge collectors are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators (STAPPA/AI_APCO, 1996). For similar air flow rates, cartridge collectors are compact in size compared to traditional bag.

The process of producing involves drying and heating the aggregates to prepare them for the asphalt cement coating. The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour.

Peters profiled estimates of capital and O&M costs (Peters, 1977). The mid-range capital cost was $6.50 per head and the mid-range O&M cost was $0.30 per head. Both of these figures are in 1975 dollars. Assuming a 10-year life and 5% discount rate for the sprinkler system, the TACs are $1.58 per head (1975$). To estimate cost per ton of PM10 reduced the emission factor (0.017 tons/head) and the control efficiency (50%) are applied to yield $186 per ton PM10 reduced (1975$). Cost Effectiveness: The cost effectiveness used in AirControlNET is $307 per ton PM reduced (1990$).

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. Wet ESPs use a stream of water, in place of rapping mechanisms, to dislodge particulate from the plates and into a sump. This control applies to various chemical manufacturing operations, including (but not limited to) adipic acid, ammonia, carbon black, charcoal, cleaners, phosphoric acids, plastics, sulfuric acid, sodium carbonate, ammonium nitrate, rubbers, ammonium phosphates, and inorganic pigments.

PM2.5 control efficiency is 95% from uncontrolled Equipment Life: 20 years Document No. 05.09.009/9010.463 III-659 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Rule Effectiveness: 100% Penetration: 100% Cost Basis: The following are cost ranges for wire-plate ESPs, developed using EPA cost- estimating spreadsheets for dry wire-plate ESPs with adjustments made to reflect wet wire-plate ESPs (EPA, 1999). Capital and operating costs are generally higher due to noncorrosive materials requirements, increased water usage, and treatment and disposal of wet effluent. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1990). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $30 to $60 per scfm Typical value is $40 per scfm O&M Costs: Range from $6 to $45 per scfm Typical value is $19 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1999). O&M costs were calculated for three model plants with flow rates of 10, 15 and 20 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. A water flow rate for the ESP was assumed to be 5 gal/min per thousand acfm. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Dust disposal 20 $/ton disposed Document No. 05.09.009/9010.463 III-660 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Wastewater treatment 1.5 $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $55 to $550 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wre-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (see References) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based Document No. 05.09.009/9010.463 III-669 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced.

The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Document No. 05.09.009/9010.463 III-670 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to point sources with coal-fired boilers.

The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later Document No. 05.09.009/9010.463 III-674 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to point sources with oil-fired boilers.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of Document No. 05.09.009/9010.463 III-695 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric Document No. 05.09.009/9010.463 III-696 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

Particulate-laden gas flows into the filter bag from the outside to the inside. The particles collected on the outside drop into a hopper below the fabric filter.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000).. Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, Document No. 05.09.009/9010.463 III-714 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). Document No. 05.09.009/9010.463 III-715 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to point sources with wood-fired boilers.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of Document No. 05.09.009/9010.463 III-718 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials.

Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric Document No. 05.09.009/9010.463 III-719 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

Cost Effectiveness: When stack flow is available the cost effectiveness varies from $53 to $337 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $148 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as Document No. 05.09.009/9010.463 III-722 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

This control is useful in the reduction of PM from construction areas, including heavy construction sites and road construction operations.

Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: The annual cost for the dust control plan ($4,900 per acre) can be calculated as the sum of the annual costs for each control technique: Site watering = $1,395 per acre ($3,720 per acre x 1 acre x 37.5 percent); Chemical stabilization = $3,506 per acre ($9,350 per acre x 1 acre x 37.5 percent). Annual emission reductions for the dust control plan can be calculated by applying the 75 percent penetration factor and overall 62.5 percent control efficiency to annual emissions. For one acre of construction activity, a 1.36 tpy reduction in PM-10 emissions is estimated for the dust control plan. Based on this information, the cost effectiveness of the dust control plan is estimated to be $3,600 per ton of PM-10 reduced (Pechan, 1997). Note: All costs are in 1990 dollars. Cost Effectiveness: The cost effectiveness is $3,600 per ton PM10 reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 1997 Document No. 05.09.009/9010.463 III-724 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Additional Information: The most complete information available pertaining to construction PM emissions control is for site watering. Site watering is an attractive option because many construction jobs already have necessary equipment and facilities and need only more personnel for this task (EPA, 1974). The length of PM emission reduction from site watering is brief, requiring more than one application a day. Chemical suppressants provide a higher level of control which is longer-lasting than site watering. The higher cost of suppressants versus watering generally precludes their use in construction areas that undergo substantial improvements (e.g., earthmoving). Chemical stabilization efficiency is dependent upon application rates. The EPA recommends that at least dilute reapplications be employed every month (EPA, 1994).

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (see References) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

The cost effectiveness at a percent excess emission rate of 0.46 percent is $5,200 per ton of PM2.5.

Costs are primarily driven by the waste stream volumetric flow rate and pollutant loading. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of Document No. 05.09.009/9010.463 III-763 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials.

Capital Costs: Range from $7 to $13 per scfm Typical value is $9 per scfm O&M Costs: Range from $9 to $25 per scfm Typical value is $14 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average cartridge cost was estimated using the costs for standard cartridge types. Capital recovery for the periodic replacement of cartridges was included in the O&M cost of the cartridges using a cartridge life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available, the cost effectiveness varies from $85 to $256 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $142 per ton PM10 reduced.

Auxiliary equipment, such as fans and ductwork, is not included (EPA, 2000). Pollutants that require an unusually high level of control or that require the filter media or the unit itself to be constructed of special materials, such as Nomex ® or stainless steel, will increase the costs of the system (EPA, 1998a). The additional costs for controlling more complex waste streams are not reflected in the estimates given below. For these types of systems, the capital cost could increase by as much as 75% and the O&M cost could increase by as much as 10%. In general, a small unit controlling a low pollutant loading will not be as cost effective as a large unit controlling a high pollutant loading (EPA, 2000). Document No. 05.09.009/9010.463 III-764 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Cartridge filters contain either a paper or nonwoven fibrous filter media (EPA, 2000). Paper media is generally made of materials such as cellulose and fiberglass. The dust cake that forms on the filter media from the collected PM can significantly increase collection efficiency (EPA, 1998b). In general, the filter media is pleated to provide a larger surface area to volume flow rate. Close pleating, however, can cause PM to bridge the pleat bottom, effectively reducing the surface collection area (EPA, 1998b). Corrugated aluminum separators are used to prevent the pleats from collapsing (Heumann, 1997). There are variety of cartridge designs and dimensions. Typical designs include flat panels, V-shaped packs or cylindrical packs (Heumann, 1997). For certain applications, two cartridges may be placed in series. Cartridge collectors are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators (STAPPA/AI_APCO, 1996).

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Document No. 05.09.009/9010.463 III-769 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1990). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced.

The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a).

The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5).

As a rule, smaller units controlling a low Document No. 05.09.009/9010.463 III-778 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow.

A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

Shaker Type) Rule Name: Not Applicable Pechan Measure Code: P2141 POD: 214 Application: This control is the addition of a mechanical shaker type fabric filter to reduce PM emissions. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags. The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly to clean the bags. This control applies to ferroalloy production operations, including (but not limited to) several processes within this industry were selected for control, basic oxygen process furnace (SCC 30300914) and EAF argon 02 decarb vessels (SCC 30300928).

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and Document No. 05.09.009/9010.463 III-784 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced.

In the basic oxygen process furnace, a mixture of 70 percent molten iron from the blast furnace and 30 percent iron scrap are melted together. Pure oxygen is blown across the top or through the molten steel to oxidize carbon and oxygen impurities, thus removing these from the steel. Basic oxygen process furnaces are large open-mouthed furnaces that can be tilted to accept a charge or to tap the molten steel to a charging ladle for transfer to an ingot mold or continuous caster. Because basic oxygen furnaces are open, they produce significant uncontrolled particulate emissions, notably during the refining stage when oxygen is being blown. Electric arc furnaces use the current passing between carbon electrodes to heat molten steel, but also use oxy-fuel burners to accelerate the initial melting process. These furnaces are charged largely with scrap iron. Significant emissions occur during charging, when the furnace roof is open, during melting, as the electrodes are lowered into the scrap and the arc is struck, and during tapping, when alloying elements are added to the melt. Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper.

The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 Dust disposal 25 $/kW-hr $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Document No. 05.09.009/9010.463 III-789 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%.

Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (see References) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

Labor rates in the EPA CEMS Cost Model are scaled to reflect 2003 labor rates (including 140 percent overhead) provided by the Bureau of Labor Statistics. The cost effectiveness at a percent excess emission rate of 0.46 percent is $5,200 per ton of PM2.5. This is based on a $34 million capital investment cost, and a $14 million total annualized cost when applied to 128 facilities. Note: All costs are in 2003 dollars.

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags. The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly to clean the bags.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Document No. 05.09.009/9010.463 III-800 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Grey iron is an alloy of iron, carbon, and silicon, containing a higher percentage of the last two elements than found in malleable iron. The high strengths are obtained by the proper adjustment of the carbon and silicon contents or by alloying. Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to gray iron foundry operations.

(1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Grey iron is an alloy of iron, carbon, and silicon, containing a higher percentage of the last two elements than found in malleable iron. The high strengths are obtained by the proper adjustment of the carbon and silicon contents or by alloying. Oil suppression can provide 75 to 99 percent control of TSP emissions. While the oil suppression system is favored because of costs, for the purpose of this study, fabric filters are being considered because they can achieve greater than 99 percent control of TSP as well as small and light particles. In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

The high strengths are obtained by the proper adjustment of the carbon and silicon contents or by alloying. The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 Document No. 05.09.009/9010.463 III-809 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An impingement-plate scrubber is a vertical chamber with plates mounted horizontally inside a hollow shell. Impingement-plate scrubbers operate as countercurrent PM collection devices. The scrubbing liquid flows down the tower while the gas stream flows upward. Contact between the liquid and the particle-laden gas occurs on the plates. The plates are equipped with openings that allow the gas to pass through. Some plates are perforated or slotted, while more complex plates have valve-like openings (EPA, 1998). This control applies to iron and steel production operations.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (10 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $2 to $11 per scfm Typical value is $7 per scfm O&M Costs: Range from $3 to $70 per scfm Typical value is $25 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for Impingement Plate Scrubbers (EPA, 1996). O&M costs were calculated for two model plants with flow rates of 1,000 and 100,000 acfm. The 1,000 acfm plant required 1 scrubber unit while the 100,000 acfm plant required 2 scrubber units. Both model plants were assumed to have 3 scrubber stages per scrubber unit. The average percentage of the total O&M cost was then calculated for each O&M cost component. The model plants were assumed to have a dust loading of 3.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An inlet water flow rate for the scrubber was assumed to be 9.4 Ibs/min. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Dust disposal 25 $/ton disposed Wastewater treatment 3.8 $/thousand gal treated Document No. 05.09.009/9010.463 III-812 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $46 to $1,200 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $431 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods. As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow (EPA, 1999). In all types of impingement-plate scrubbers, the scrubbing liquid flows across each plate and down the inside of the tower onto the plate below. After the bottom plate, the liquid and collected PM flow out of the bottom of the tower. Impingement-plate scrubbers are usually designed to provide operator access to each tray, making them relatively easy to clean and maintain. Consequently, impingement-plate scrubbers are more suitable for PM collection than packed-bed scrubbers. Particles greater than 1 um in aerodynamic diameter can be collected effectively by impingement- plate scrubbers, but many particles <1 um in aerodynamic diameter will penetrate these devices (EPA, 1998). The simplest impingement-plate scrubber is the sieve plate, which has round perforations (EPA, 1999). In this type of scrubber, the scrubbing liquid flows over the plates and the gas flows up through the holes. The gas velocity prevents the liquid from flowing down through the perforations. Gas-liquid-particle contact is achieved within the froth generated by the gas passing through the liquid layer. Complex plates, such as bubble cap or baffle plates, introduce an additional means of collecting PM. The bubble caps and baffles placed above the plate perforations force the gas to turn before escaping the layer of liquid. While the gas turns to avoid the obstacles, most PM cannot and is collected by impaction on the caps or baffles. Bubble caps and the like also prevent liquid from flowing down the perforations if the gas flow is reduced (EPA, 1998). References: EPA, 1996.

(1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Grey iron is an alloy of iron, carbon, and silicon, containing a higher percentage of the last two elements than found in malleable iron. The high strengths are obtained by the proper adjustment of the carbon and silicon contents or by alloying. Oil suppression can provide 75 to 99 percent control of TSP emissions. While the oil suppression system is favored because of costs, for the purpose of this study, fabric filters are being considered because they can achieve greater than 99 percent control of TSP as well as small and light particles (EPA, 1999). The costs do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods (EPA, 1999). As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow. By product coke production is used to manufacture metallurgical coke by heating high-grade bituminous coal (low sulfur and low ash) in an enclosed oven chamber without oxygen. The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Document No. 05.09.009/9010.463 III-827 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Steel normally is produced in either basic oxygen process furnaces or electric arc furnaces. In the basic oxygen process furnace, a mixture of 70 percent molten iron from the blast furnace and 30 percent iron scrap are melted together. Pure oxygen is blown across the top or through the molten steel to oxidize carbon and oxygen impurities, thus removing these from the steel. Basic oxygen process furnaces are large open-mouthed furnaces that can be tilted to accept a charge or to tap the molten steel to a charging ladle for transfer to an ingot mold or continuous caster. Because basic oxygen furnaces are open, they produce significant uncontrolled particulate emissions, notably during the refining stage when oxygen is being blown. Electric arc furnaces use the current passing between carbon electrodes to heat molten steel, but also use oxy-fuel burners to accelerate the initial melting process. These furnaces are charged largely with scrap iron. Significant emissions occur during charging, when the furnace roof is open, during melting, as the electrodes are lowered into the scrap and the arc is struck, and during tapping, when alloying elements are added to the melt. The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials Document No. 05.09.009/9010.463 III-828 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Document No. 05.09.009/9010.463 III-836 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 Dust disposal 25 $/kW-hr $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Steel normally is produced in either basic oxygen process furnaces or electric arc furnaces. In the basic oxygen process furnace, a mixture of 70 percent molten iron from the blast furnace and 30 percent iron scrap are melted together. Pure oxygen is blown across the top or through the molten steel to oxidize carbon and oxygen impurities, thus removing these from the steel. Basic oxygen process furnaces are large open-mouthed furnaces that can be tilted to accept a charge or to tap the molten steel to a charging ladle for transfer to an ingot mold or continuous caster. Because basic oxygen furnaces are open, they produce significant uncontrolled particulate emissions, notably during the refining stage when oxygen is being blown. Electric arc furnaces use the current passing between carbon electrodes to heat molten steel, but also use oxy-fuel burners to accelerate the initial melting process. These furnaces are charged largely with scrap iron. Significant emissions occur during charging, when the furnace roof is open, during melting, as the electrodes are lowered into the scrap and the arc is struck, and during tapping, when alloying elements are added to the melt. In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the Document No. 05.09.009/9010.463 III-837 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

Capital and operating costs are generally higher due to noncorrosive materials requirements, increased water usage, and treatment and disposal of wet effluent. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1990). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $30 to $60 per scfm Typical value is $40 per scfm Document No. 05.09.009/9010.463 III-840 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES O&M Costs: Range from $6 to $45 per scfm Typical value is $19 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1999). O&M costs were calculated for three model plants with flow rates of 10, 15 and 20 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. A water flow rate for the ESP was assumed to be 5 gal/min per thousand acfm. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Dust disposal 20 $/ton disposed Wastewater treatment 1.5 $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $55 to $550 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Steel normally is produced in either basic oxygen process furnaces or electric arc furnaces.

These furnaces are charged largely with scrap iron. Significant emissions occur during charging, when the furnace roof is open, during melting, as the electrodes are lowered into the scrap and the arc is struck, and during tapping, when alloying elements are added to the melt. Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted Document No. 05.09.009/9010.463 III-841 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency.

These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wire-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection. This control applies to iron and steel production operations.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $9 to $84 per scfm Typical value is $34 per scfm O&M Costs: Range from $6 to $27 per scfm Document No. 05.09.009/9010.463 111-844 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Typical value is $13 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $53 to $337 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $148 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Steel normally is produced in either basic oxygen process furnaces or electric arc furnaces. In the basic oxygen process furnace, a mixture of 70 percent molten iron from the blast furnace and 30 percent iron scrap are melted together. Pure oxygen is blown across the top or through the molten steel to oxidize carbon and oxygen impurities, thus removing these from the steel. Basic oxygen process furnaces are large open-mouthed furnaces that can be tilted to accept a charge or to tap the molten steel to a charging ladle for transfer to an ingot mold or continuous caster. Because basic oxygen furnaces are open, they produce significant uncontrolled particulate emissions, notably during the refining stage when oxygen is being blown. Electric arc furnaces use the current passing between carbon electrodes to heat molten steel, but also use oxy-fuel burners to accelerate the initial melting process. These furnaces are charged largely with scrap iron. Significant emissions occur during charging, when the furnace roof is open, during melting, as the electrodes are lowered into the scrap and the arc is struck, and during tapping, when alloying elements are added to the melt. The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Document No. 05.09.009/9010.463 III-845 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (10 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $3 to $28 per scfm Typical value is $11 per scfm O&M Costs: Range from $4 to $119 per scfm Typical value is $42 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for Impingement Plate Document No. 05.09.009/9010.463 III-848 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Scrubbers (EPA, 1996). O&M costs were calculated for two model plants with flow rates of 2,000 and 150,000 acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. The model plants were assumed to have a dust loading of 3.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An inlet water flow rate for the scrubber was assumed to be 9.4 Ibs/min. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 Process water price 0.20 Dust disposal 25 Wastewater treatment 3.8 $/kW-hr $/1000 gal $/ton disposed $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $76 to $2,100 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $751 per ton PM10 reduced.

In the basic oxygen process furnace, a mixture of 70 percent molten iron from the blast furnace and 30 percent iron scrap are melted together.

Significant emissions occur during charging, when the furnace roof is open, during melting, as the electrodes are lowered into the scrap and the arc is struck, and during tapping, when alloying elements are added to the melt. The costs do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods (EPA, 1999). As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow. By product coke production is used to manufacture metallurgical coke by heating high-grade bituminous coal (low sulfur and low ash) in an enclosed oven chamber without oxygen. The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi Document No. 05.09.009/9010.463 III-849 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method.

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Particulate-laden gas flows into the filter bag from the outside to the inside. The particles collected on the outside drop into a hopper below the fabric filter.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Document No. 05.09.009/9010.463 III-855 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced.

The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur Document No. 05.09.009/9010.463 III-857 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

The particles collect on the inside of the bags, forming a filter cake.

The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative Document No. 05.09.009/9010.463 III-863 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

Capital Costs: Range from $30 to $60 per scfm Typical value is $40 per scfm O&M Costs: Range from $6 to $45 per scfm Typical value is $19 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1999). O&M costs were calculated for three model plants with flow rates of 10, 15 and 20 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. A water flow rate for the ESP was assumed to be 5 gal/min per thousand acfm. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 Process water price 0.20 Dust disposal 20 Wastewater treatment 1.5 $/kW-hr $/1000 gal $/ton disposed $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $55 to $550 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced. (1995$) Comments: Document No. 05.09.009/9010.463 III-866 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Status: Demonstrated Last Reviewed: 2001 Additional Information: Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wire-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials.

O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a).

The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Cost Effectiveness: When stack flow is available the cost effectiveness varies from $76 to $2,100 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $751 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The costs do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods (EPA, 1999). As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow. By product coke production is used to manufacture metallurgical coke by heating high-grade bituminous coal (low sulfur and low ash) in an enclosed oven chamber without oxygen. The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi Document No. 05.09.009/9010.463 III-8 74 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials.

(1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, Document No. 05.09.009/9010.463 III-882 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Auxiliary equipment, such as fans and ductwork, is not included (EPA, 2000). Pollutants that require an unusually high level of control or that require the filter media or the unit itself to be constructed of special materials, such as Nomex ® or stainless steel, will increase the costs of the system (EPA, 1998a). The additional costs for controlling more complex waste streams are not reflected in the estimates given below. For these types of systems, the capital cost could increase by as much as 75% and the O&M cost could increase by as much as 10%. In general, a small unit controlling a low pollutant loading will not be as cost effective as a large unit controlling a high pollutant loading (EPA, 2000). Cartridge filters contain either a paper or nonwoven fibrous filter media (EPA, 2000). Paper media is generally made of materials such as cellulose and fiberglass. The dust cake that forms on the filter media from the collected PM can significantly increase collection efficiency (EPA, 1998b). In general, the filter media is pleated to provide a larger surface area to volume flow rate. Close pleating, however, can cause PM to bridge the pleat bottom, effectively reducing the surface collection area (EPA, 1998b). Corrugated aluminum separators are used to prevent the pleats from collapsing (Heumann, 1997). There are variety of cartridge designs and dimensions. Typical designs include flat panels, V-shaped packs or cylindrical packs (Heumann, 1997). For certain applications, two cartridges may be placed in series. Cartridge collectors are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators (STAPPA/AI_APCO, 1996). For similar air flow rates, cartridge collectors are compact in size compared to traditional bag References: EPA, 1998b: U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, "OAQPS Control Cost Manual," Fifth Edition, Chapter 5, EPA 453/B-96-001, Research Triangle Park, NC.

The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b).

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Particulate-laden gas flows into the filter bag from the outside to the inside. The particles collected on the outside drop into a hopper below the fabric filter. During pulse-jet cleaning, a short burst of high pressure air is injected into the bags, dislodging the dust cake. This control applies to operations with coal-fired boilers.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Document No. 05.09.009/9010.463 III-899 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced.

The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection Document No. 05.09.009/9010.463 III-901 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

(1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-904 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: There are two major coal combustion techniques in industrial boilers - suspension firing and grate firing. Suspension firing is the primary combustion mechanism in pulverized-coal-fired and cyclone- fired units and overfeed stoker-fired units. Both mechanisms are employed in spreader stokers. Pulverized-coal and cyclone furnaces are used primarily in utility and large industrial boilers. Stokers constitute the most practical method of firing coal for small industrial units. In spreader stokers, a flipping mechanism throws the coal into the furnace and onto a moving fuel bed. Combustion occurs partly in suspension and partly on the grate. In overfeed stokers, coal is fed onto a traveling bed or vibrating grate, and it burns on the fuel bed as it progresses through the furnace (AWMA, 1992). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection. This control applies to operations with coal-fired boilers.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Document No. 05.09.009/9010.463 III-907 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $9 to $84 per scfm Typical value is $34 per scfm O&M Costs: Range from $6 to $27 per scfm Typical value is $13 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $53 to $337 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $148 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-908 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: There are two major coal combustion techniques in industrial boilers - suspension firing and grate firing. Suspension firing is the primary combustion mechanism in pulverized-coal-fired and cyclone- fired units and overfeed stoker-fired units. Both mechanisms are employed in spreader stokers. Pulverized-coal and cyclone furnaces are used primarily in utility and large industrial boilers. Stokers constitute the most practical method of firing coal for small industrial units. In spreader stokers, a flipping mechanism throws the coal into the furnace and onto a moving fuel bed. Combustion occurs partly in suspension and partly on the grate. In overfeed stokers, coal is fed onto a traveling bed or vibrating grate, and it burns on the fuel bed as it progresses through the furnace (AWMA, 1992). The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

A scrubber is a type of technology that removes air pollutants by inertial and diffusional interception. A venturi scrubber accelerates the waste gas stream to atomize the scrubbing liquid and to improve gas-liquid contact. This control applies to operations with coal-fired boilers.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed Document No. 05.09.009/9010.463 III-911 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (10 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $3 to $28 per scfm Typical value is $11 per scfm O&M Costs: Range from $4 to $119 per scfm Typical value is $42 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for Impingement Plate Scrubbers (EPA, 1996). O&M costs were calculated for two model plants with flow rates of 2,000 and 150,000 acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. The model plants were assumed to have a dust loading of 3.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An inlet water flow rate for the scrubber was assumed to be 9.4 Ibs/min. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Dust disposal 25 $/ton disposed Wastewater treatment 3.8 $/thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $76 to $2,100 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $751 per ton PM10 reduced.

In overfeed stokers, coal is fed onto a traveling bed or vibrating grate, and it burns on the fuel bed as it progresses through the furnace (AWMA, 1992). The costs do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods (EPA, 1999). As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow. By product coke production is used to manufacture metallurgical coke by heating high-grade bituminous coal (low sulfur and low ash) in an enclosed oven chamber without oxygen. The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: AWMA, 1992: Air & Waste Management Association, "Air Pollution Engineering Manual," edited by A.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies operations that have industrial boilers fired with liquid waste, including waste oil.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of Document No. 05.09.009/9010.463 III-923 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: ESPs are used when control efficiencies of 95 percent or more are required. In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion Document No. 05.09.009/9010.463 III-924 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

A scrubber is a type of technology that removes air pollutants by inertial and diffusional interception. A venturi scrubber accelerates the waste gas stream to atomize the scrubbing liquid and to improve gas-liquid contact. This control applies to operations with oil-fired boilers.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (10 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of Document No. 05.09.009/9010.463 III-941 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $3 to $28 per scfm Typical value is $11 per scfm O&M Costs: Range from $4 to $119 per scfm Typical value is $42 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for Impingement Plate Scrubbers (EPA, 1996). O&M costs were calculated for two model plants with flow rates of 2,000 and 150,000 acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. The model plants were assumed to have a dust loading of 3.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An inlet water flow rate for the scrubber was assumed to be 9.4 Ibs/min. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 Process water price 0.20 Dust disposal 25 Wastewater treatment 3.8 $/kW-hr $/1000 gal $/ton disposed $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $76 to $2,100 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $751 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Fuel-oil types include heavier fuel oil derived from crude petroleum are referred to as residual oils and are graded from No. 4 (very light residual) to No. 6 (residual). Emissions from fuel oil combustion depend on the grade and composition of the oil, the type and size of the boiler, firing practices used, and the level of equipment maintenance. The costs do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods (EPA, 1999). As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow. Document No. 05.09.009/9010.463 III-942 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES By product coke production is used to manufacture metallurgical coke by heating high-grade bituminous coal (low sulfur and low ash) in an enclosed oven chamber without oxygen. The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001).

Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The burning of wood and bark waste in boilers is mostly confined to industries where wood and bark waste is available as a byproduct. Wood and bark waste is burned to obtain heat energy and to alleviate possible solid waste disposal problems. In boilers, the waste is burned in the form of hogged wood, sawdust, shavings, chips, sander dust, or wood trim. Bark is the major type of waste burned in "power" boilers at pulp and paper mills. At lumber, furniture, and plywood plants, either a mixture of wood and bark waste or wood waste alone is burned most frequently (EPA, 1995). The cost estimates assume a conventional design under typical operating conditions and do not Document No. 05.09.009/9010.463 III-957 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to operations with wood-fired industrial boilers, including those classified under the following SCCs 10200901, 10200902, 10200903, 10200904, 10200905 , 10200906, 10200907.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001).

The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet.

The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The burning of wood and bark waste in boilers is mostly confined to industries where wood and bark waste is available as a byproduct. Wood and bark waste is burned to obtain heat energy and to alleviate possible solid waste disposal problems. In boilers, the waste is burned in the form of hogged wood, sawdust, shavings, chips, sander dust, or wood trim. Bark is the major type of waste burned in "power" boilers at pulp and paper mills. At lumber, furniture, and plywood plants, either a mixture of wood and bark waste or wood waste alone is burned most frequently (EPA, 1995). ESPs are used when control efficiencies of 95 percent or more are required. In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging Document No. 05.09.009/9010.463 III-961 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Wood and bark waste is burned to obtain heat energy and to alleviate possible solid waste disposal problems.

Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied).

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Particulate-laden gas flows into the filter bag from the outside to the inside. The particles collected on the outside drop into a hopper below the fabric filter. During pulse-jet cleaning, a short burst of high pressure air is injected into the bags, dislodging the dust cake.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag Document No. 05.09.009/9010.463 III-976 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The largest source of particulate emissions at a cement plant is the kiln used to produce clinker. Cement kilns are rotary kilns, which are slowly rotating refractory-lined steel cylinders inclined slightly from the horizontal. Raw materials are fed into the top end of the kiln and spend several hours traversing the kiln. In wet process kilns (SCC 30500706), the raw materials are fed as a wet slurry. During this time, the raw materials are heated by a flame at the discharge end of the kiln. This heating dries the raw materials, converts limestone to lime, and promotes reaction between and fusion of the separate ingredients to form clinker. Clinker exiting the kiln is fed to a clinker cooler (SCC 30500714) for cooling before storage and further processing (STAPPA/ALAPCO, 1996). The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the Document No. 05.09.009/9010.463 III-977 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

(EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake.

Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to cement manufacturing operations.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be Document No. 05.09.009/9010.463 III-984 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The largest source of particulate emissions at a cement plant is the kiln used to produce clinker. Cement kilns are rotary kilns, which are slowly rotating refractory-lined steel cylinders inclined slightly from the horizontal. Raw materials are fed into the top end of the kiln and spend several hours traversing the kiln. In wet process kilns (SCC 30500706), the raw materials are fed as a wet slurry. During this time, the raw materials are heated by a flame at the discharge end of the kiln. This heating dries the raw materials, converts limestone to lime, and promotes reaction between and fusion of the separate ingredients to form clinker. Clinker exiting the kiln is fed to a clinker cooler (SCC 30500714) for cooling before storage and further processing (STAPPA/ALAPCO, 1996). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles Document No. 05.09.009/9010.463 III-985 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

The cost estimates assume a conventional design under typical operating conditions. Auxiliary equipment, such as fans and ductwork, is not included (EPA, 2000). Pollutants that require an unusually high level of control or that require the filter media or the unit itself to be constructed of special materials, such as Nomex ® or stainless steel, will increase the costs of the system (EPA, 1998a). The additional costs for controlling more complex waste streams are not reflected in the estimates given below. For these types of systems, the capital cost could increase by as much as 75% and the O&M cost could increase by as much as 10%. In general, a small unit controlling a low pollutant loading will not be as cost effective as a large unit controlling a high pollutant loading (EPA, 2000). Cartridge filters contain either a paper or nonwoven fibrous filter media (EPA, 2000). Paper media is generally made of materials such as cellulose and fiberglass. The dust cake that forms on the filter media from the collected PM can significantly increase collection efficiency (EPA, 1998b). In general, the filter media is pleated to provide a larger surface area to volume flow rate. Close pleating, however, can cause PM to bridge the pleat bottom, effectively reducing the surface collection area (EPA, 1998b). Corrugated aluminum separators are used to prevent the pleats from collapsing (Heumann, 1997). There are variety of cartridge designs and dimensions. Typical designs include flat panels, V-shaped packs or cylindrical packs (Heumann, 1997). For certain applications, two cartridges may be placed in series. Cartridge collectors are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators (STAPPA/AI_APCO, 1996). For similar air flow rates, cartridge collectors are compact in size compared to traditional bag References: EPA, 1998b: U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, "OAQPS Control Cost Manual," Fifth Edition, Chapter 5, EPA 453/B-96-001, Research Triangle Park, NC.

The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the Document No. 05.09.009/9010.463 III-993 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied).

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust Document No. 05.09.009/9010.463 III-1000 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Coal mining, cleaning and material handling (305010) consists of the preparation and handling of coal to upgrade its value. For the purpose of this study, thermal dryers, pneumatic coal cleaning and truck/vehicle travel are the sources considered. Thermal dryers are used at the end of the series of cleaning operations to remove moisture from coal, thereby reducing freezing problems and weight, and increasing the heating value. The major portion of water is removed by the use of screens, thickeners, and cyclones. The coal is then dried in a thermal dryer. Particulate emissions result from the entrainment of fine coal particles during the thermal drying process (EPA, 1995). Pneumatic coal-cleaning equipment classifies bituminous coal by size or separates bituminous coal from refuse by application of air streams. Fugitive PM emissions result when haul trucks or other vehicles travel on unpaved roads or surfaces. The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Document No. 05.09.009/9010.463 III-1001 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection Document No. 05.09.009/9010.463 III-1005 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Costs are primarily driven by the waste stream volumetric flow rate and pollutant loading. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $7 to $13 per scfm Typical value is $9 per scfm O&M Costs: Range from $9 to $25 per scfm Typical value is $14 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average cartridge cost was estimated using the costs for standard Document No. 05.09.009/9010.463 III-1008 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES cartridge types. Capital recovery for the periodic replacement of cartridges was included in the O&M cost of the cartridges using a cartridge life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available, the cost effectiveness varies from $85 to $256 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $142 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Coal mining, cleaning and material handling (305010) consists of the preparation and handling of coal to upgrade its value. For the purpose of this study, thermal dryers, pneumatic coal cleaning and truck/vehicle travel are the sources considered. Thermal dryers are used at the end of the series of cleaning operations to remove moisture from coal, thereby reducing freezing problems and weight, and increasing the heating value. The major portion of water is removed by the use of screens, thickeners, and cyclones. The coal is then dried in a thermal dryer. Particulate emissions result from the entrainment of fine coal particles during the thermal drying process (EPA, 1995). Pneumatic coal-cleaning equipment classifies bituminous coal by size or separates bituminous coal from refuse by application of air streams. Fugitive PM emissions result when haul trucks or other vehicles travel on unpaved roads or surfaces. The cost estimates assume a conventional design under typical operating conditions. Auxiliary equipment, such as fans and ductwork, is not included (EPA, 2000). Pollutants that require an unusually high level of control or that require the filter media or the unit itself to be constructed of special materials, such as Nomex ® or stainless steel, will increase the costs of the system (EPA, 1998a). The additional costs for controlling more complex waste streams are not reflected in the estimates given below. For these types of systems, the capital cost could increase by as much as 75% and the O&M cost could increase by as much as 10%. In general, a small unit controlling a low pollutant loading will not be as cost effective as a large unit controlling a high pollutant loading (EPA, 2000). Cartridge filters contain either a paper or nonwoven fibrous filter media (EPA, 2000). Paper media is generally made of materials such as cellulose and fiberglass. The dust cake that forms on the filter media from the collected PM can significantly increase collection efficiency (EPA, 1998b). In general, the filter media is pleated to provide a larger surface area to volume flow rate. Close pleating, however, can cause PM to bridge the pleat bottom, effectively reducing the surface collection area (EPA, 1998b). Corrugated aluminum separators are used to prevent the pleats from collapsing (Heumann, 1997). There are variety of cartridge designs and dimensions. Typical designs include flat panels, V-shaped packs or cylindrical packs (Heumann, 1997). For certain applications, two cartridges may be placed in series. Cartridge collectors are useful for collecting particles with resistivities either too low or too high for Document No. 05.09.009/9010.463 III-1009 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES collection with electrostatic precipitators (STAPPA/ALAPCO, 1996).

When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs.

The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%.

Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency.

It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (10 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $3 to $28 per scfm Typical value is $11 per scfm O&M Costs: Range from $4 to $119 per scfm Typical value is $42 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for Impingement Plate Document No. 05.09.009/9010.463 III-1016 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Scrubbers (EPA, 1996). O&M costs were calculated for two model plants with flow rates of 2,000 and 150,000 acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. The model plants were assumed to have a dust loading of 3.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An inlet water flow rate for the scrubber was assumed to be 9.4 Ibs/min. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Dust disposal 25 $/ton disposed Wastewater treatment 3.8 $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $76 to $2,100 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $751 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Thermal dryers are used at the end of the series of cleaning operations to remove moisture from coal, thereby reducing freezing problems and weight, and increasing the heating value. The major portion of water is removed by the use of screens, thickeners, and cyclones. The coal is then dried in a thermal dryer. Particulate emissions result from the entrainment of fine coal particles during the thermal drying process (EPA, 1995). Pneumatic coal-cleaning equipment classifies bituminous coal by size or separates bituminous coal from refuse by application of air streams. Fugitive PM emissions result when haul trucks or other vehicles travel on unpaved roads or surfaces. The costs do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods (EPA, 1999). As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow. By product coke production is used to manufacture metallurgical coke by heating high-grade bituminous coal (low sulfur and low ash) in an enclosed oven chamber without oxygen. The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). Document No. 05.09.009/9010.463 III-1017 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent.

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Particulate-laden gas flows into the filter bag from the outside to the inside. The particles collected on the outside drop into a hopper below the fabric filter. During pulse-jet cleaning, a short burst of high pressure air is injected into the bags, dislodging the dust cake. This control applies to miscellaneous mineral production operations including (but not limited to) brick manufacture, calcium carbide operations, clay and fly ash sintering, concrete batching, gypsum manufacturing, lime production, phosphate rock operations, sand production, fiberglass manufacturing and glass manufacturing operations. Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Document No. 05.09.009/9010.463 III-1028 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $42 to $266 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. Document No. 05.09.009/9010.463 III-1029 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Shaker Type) Rule Name: Not Applicable Pechan Measure Code: P2212 POD: 221 Application: This control is the addition of a mechanical shaker type fabric filter to reduce PM emissions. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags. The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly to clean the bags. This control applies to miscellaneous mineral production operations including (but not limited to) brick manufacture, calcium carbide operations, clay and fly ash sintering, concrete batching, gypsum manufacturing, lime production, phosphate rock operations, sand production, fiberglass manufacturing and glass manufacturing operations.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag Document No. 05.09.009/9010.463 III-103 6 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions. Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, Document No. 05.09.009/9010.463 III-103 7 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to mineral production operations not classified as cement operations, coat cleaning, or stone quarrying.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Document No. 05.09.009/9010.463 III-1044 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Material handling operations including crushing, grinding, and screening, can produce significant PM emissions. Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. Wet ESPs use a stream of water, in place of rapping mechanisms, to dislodge particulate from the plates and into a sump. This control applies to miscellaneous mineral production operations including (but not limited to) brick manufacture, calcium carbide operations, clay and fly ash sintering, concrete batching, gypsum manufacturing, lime production, phosphate rock operations, sand production, fiberglass manufacturing and glass manufacturing operations. Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions.

Capital and operating costs are generally higher due to noncorrosive materials requirements, increased water usage, and treatment and disposal of wet effluent. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1990). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials.

The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Dust disposal 20 $/ton disposed Wastewater treatment 1.5 $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $55 to $550 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced.

Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wre-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond Document No. 05.09.009/9010.463 III-105 3 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

Costs are primarily driven by the waste stream volumetric flow rate and pollutant loading. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $7 to $13 per scfm Typical value is $9 per scfm O&M Costs: Range from $9 to $25 per scfm Typical value is $14 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average cartridge cost was estimated using the costs for standard cartridge types. Capital recovery for the periodic replacement of cartridges was included in the O&M cost of the cartridges using a cartridge life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Document No. 05.09.009/9010.463 III-1060 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $85 to $256 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $142 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions. Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). The cost estimates assume a conventional design under typical operating conditions. Auxiliary equipment, such as fans and ductwork, is not included (EPA, 2000). Pollutants that require an unusually high level of control or that require the filter media or the unit itself to be constructed of special materials, such as Nomex ® or stainless steel, will increase the costs of the system (EPA, 1998a). The additional costs for controlling more complex waste streams are not reflected in the estimates given below. For these types of systems, the capital cost could increase by as much as 75% and the O&M cost could increase by as much as 10%. In general, a small unit controlling a low pollutant loading will not be as cost effective as a large unit controlling a high pollutant loading (EPA, 2000). Cartridge filters contain either a paper or nonwoven fibrous filter media (EPA, 2000). Paper media is generally made of materials such as cellulose and fiberglass. The dust cake that forms on the filter media from the collected PM can significantly increase collection efficiency (EPA, 1998b). In general, the filter media is pleated to provide a larger surface area to volume flow rate. Close pleating, however, can cause PM to bridge the pleat bottom, effectively reducing the surface collection area (EPA, 1998b). Corrugated aluminum separators are used to prevent the pleats from collapsing (Heumann, 1997). There are variety of cartridge designs and dimensions. Typical designs include flat panels, V-shaped packs or cylindrical packs (Heumann, 1997). For certain applications, two cartridges may be placed in series. Cartridge collectors are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators (STAPPA/AI_APCO, 1996). For similar air flow rates, cartridge collectors are compact in size compared to traditional bag.

Document No. 05.09.009/9010.463 III-1062 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Source Category: Mineral Products - Other Control Measure Name: Fabric Filter (Reverse-Air Cleaned Type) Rule Name: Not Applicable Pechan Measure Code: P2216 POD: 221 Application: This control is the use of a reverse-air cleaned fabric filter to reduce PM emissions from waste streams. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection. This control applies to miscellaneous mineral production operations including (but not limited to) brick manufacture, calcium carbide operations, clay and fly ash sintering, concrete batching, gypsum manufacturing, lime production, phosphate rock operations, sand production, fiberglass manufacturing and glass manufacturing operations. Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $9 to $84 per scfm Typical value is $34 per scfm O&M Costs: Range from $6 to $27 per scfm Typical value is $13 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag Document No. 05.09.009/9010.463 III-1068 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $53 to $337 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $148 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions. Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to Document No. 05.09.009/9010.463 III-1069 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $6 to $26 per scfm Typical value is $13 per scfm O&M Costs: Range from $5 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars.

The default cost effectiveness value, used when stack flow is not available, is $117 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). The cost estimates assume a conventional design under typical operating conditions and do not include auxiliary equipment such as fans and ductwork. The costs for pulse-jet cleaned systems are generated using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 75% and the operational and maintenance (O&M) cost could increase by as much as 20% (EPA, 2000). In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters Document No. 05.09.009/9010.463 III-1082 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars.

The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Materials handling operations including crushing, grinding, and screening, can produce significant PM emissions. Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998).

Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wire-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

Costs are primarily driven by the waste stream volumetric flow rate and pollutant loading. When stack gas flow rate data was available, the costs and Document No. 05.09.009/9010.463 III-1096 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $7 to $13 per scfm Typical value is $9 per scfm O&M Costs: Range from $9 to $25 per scfm Typical value is $14 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average cartridge cost was estimated using the costs for standard cartridge types. Capital recovery for the periodic replacement of cartridges was included in the O&M cost of the cartridges using a cartridge life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $85 to $256 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $142 per ton PM10 reduced.

Drying, the heating of minerals or mineral products to remove water, and calcination, heating to higher temperatures to remove chemically bound water and other compounds, are normally performed in dedicated, closed units. Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). The cost estimates assume a conventional design under typical operating conditions. Auxiliary equipment, such as fans and ductwork, is not included (EPA, 2000). Pollutants that require an unusually high level of control or that require the filter media or the unit itself to be constructed of special materials, such as Nomex ® or stainless steel, will increase the costs of the system (EPA, 1998a). The additional costs for controlling more complex waste streams are not reflected in the estimates given below. For these types of systems, the capital cost could increase by as much as 75% and the O&M cost could increase by as much as 10%. In general, a small unit controlling a low pollutant loading will not be as cost effective as a large unit controlling a high pollutant loading (EPA, 2000). Cartridge filters contain either a paper or nonwoven fibrous filter media (EPA, 2000). Paper media is generally made of materials such as cellulose and fiberglass. The dust cake that forms on the filter media from the collected PM can significantly increase collection efficiency (EPA, 1998b). In general, the filter media is pleated to provide a larger surface area to volume flow rate. Close pleating, however, can cause PM to bridge the pleat bottom, effectively reducing the surface collection area (EPA, 1998b). Corrugated aluminum separators are used to prevent the pleats from collapsing (Heumann, 1997). There are variety of cartridge designs and dimensions. Typical designs include flat panels, V-shaped packs or cylindrical packs (Heumann, 1997). For certain applications, two cartridges may be placed in series. Cartridge collectors are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators (STAPPA/AI_APCO, 1996). For similar air flow rates, cartridge collectors are compact in size compared to traditional bag References: EPA, 1998b: U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, "OAQPS Control Cost Manual," Fifth Edition, Chapter 5, EPA 453/B-96-001, Research Triangle Park, NC.

The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 Document No. 05.09.009/9010.463 III-1102 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Emissions from these units will be through process vents, to which PM controls can be applied relatively simply. Fugitive dust emissions may come from paved and unpaved roads in plants and from raw material and product loading, unloading, and storage (STAPPA/ALAPCO, 1996). The costs do not include costs for post-treatment or disposal of used solvent or waste. Actual costs can be substantially higher than in the ranges shown for applications which require expensive materials, solvents, or treatment methods (EPA, 1999). As a rule, smaller units controlling a low concentration waste stream will be much more expensive (per unit volumetric flow rate) than a large unit cleaning a high pollutant load flow. By product coke production is used to manufacture metallurgical coke by heating high-grade bituminous coal (low sulfur and low ash) in an enclosed oven chamber without oxygen. The resulting solid material consists of elemental carbon and any minerals (ash) that were present in the coal blend that did not volatilize during the process. Sources of air emissions consist of coke oven doors, coke oven lids and off-takes, coke oven charging, coke oven pushing, coke oven underfire stack, coke quenching, battery venting, and coke by-product-recovery plants. A venturi scrubber accelerates the waste gas stream to improve gas-liquid contact. In a venturi scrubber, a "throat"' section is built into the duct that forces the gas stream to accelerate (EPA, 1999). As the gas enters the venturi throat, both gas velocity and turbulence increase. After the throat section, the mixture decelerates, and further impacts occur causing the droplets to agglomerate. Once the particles have been captured by the liquid, the wetted PM and excess liquid are separated from the gas stream through entrainment. This section usually consists of a cyclonic separator and/or a mist eliminator (EPA, 1998; Corbitt, 1990). For PM applications, wet scrubbers generate waste, either a slurry or wet sludge. This creates the need for both wastewater treatment and solid waste disposal. Initially, the slurry is treated to separate the solid waste from the water (EPA, 1999). The treated water can then be reused or discharged. Once the water is removed, the remaining waste will be in the form of a solid or sludge. If the solid waste is inert and nontoxic, it can generally be land filled. Hazardous wastes will have more stringent procedures for disposal. In some cases, the solid waste may have value and can be sold or recycled (EPA, 1998). References: Corbitt, 1990: "Standard Handbook of Environmental Engineering," edited by Robert A.

Document No. 05.09.009/9010.463 III-1107 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Source Category: Municipal Waste Incineration Control Measure Name: Dry ESP-Wire Plate Type Rule Name: Not Applicable Pechan Measure Code: P2261 POD: 226 Application: This control is the use of dry electrostatic precipitators (ESP) to reduce PM emissions. An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to municipal waste incineration operations classified under SCCs: 50100101, 50100102, 50100103, 50100105, and 50100107.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets Document No. 05.09.009/9010.463 III-1108 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the Document No. 05.09.009/9010.463 III-1109 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

Shaker Type) Rule Name: Not Applicable Pechan Measure Code: P2111 POD: 211 Application: This control is the addition of a mechanical shaker type fabric filter to reduce PM emissions. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags. The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly to clean the bags. This control applies to aluminum processing and production operations.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed Document No. 05.09.009/9010.463 III-l 111 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000).. Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-l 112 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

(1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-l 118 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wire-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and Document No. 05.09.009/9010.463 III-l 121 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $9 to $84 per scfm Typical value is $34 per scfm O&M Costs: Range from $6 to $27 per scfm Typical value is $13 per scfm Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $53 to $337 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $148 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving Document No. 05.09.009/9010.463 III-1122 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied).

(1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. Wet ESPs use a stream of water, in place of rapping mechanisms, to dislodge particulate from the plates and into a sump.

Capital and operating costs are generally higher due to noncorrosive materials requirements, increased water usage, and treatment and disposal of wet effluent. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1990). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $30 to $60 per scfm Typical value is $40 per scfm O&M Costs: Range from $6 to $45 per scfm Typical value is $19 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1999). O&M costs were calculated for three model plants with flow rates of 10, 15 and 20 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. A water flow rate for the ESP was assumed to be 5 gal/min per thousand acfm. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Document No. 05.09.009/9010.463 III-l 136 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Process water price 0.20 $/1000gal Dust disposal 20 $/ton disposed Wastewater treatment 1.5 $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $55 to $550 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wre-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

(1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic Document No. 05.09.009/9010.463 III-l 141 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 Document No. 05.09.009/9010.463 III-1147 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced.

The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

(1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-l 151 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream.

Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wire-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method. The original calculation method keeps actual emissions at NEI amounts, and is used in AirControlNET to avoid having to re-estimate NEI emissions to include excess emissions.

In this improved technique scenario, the monitoring technique is upgraded to a PM continuous emission monitor. This improved monitoring technique also results in an increase to the monitoring frequency because a PM CEMS can make a measurement every 7.5 minutes. The monitoring frequency increases from once per day to eight times per hour.

The gas stream is drawn from beneath a cell plate in the floor and into the filter bags. The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly to clean the bags.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $8 to $71 per scfm Typical value is $29 per scfm O&M Costs: Range from $4 to $24 per scfm Typical value is $11 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Document No. 05.09.009/9010.463 III-1166 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Dust disposal 25 $/ton disposed Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $37 to $303 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $126 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Cost estimates assume a conventional design under typical operating conditions. The costs do not include auxiliary equipment such as fans and ductwork. (EPA, 2000) Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5).

(1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs.

The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Document No. 05.09.009/9010.463 III-1173 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Dust disposal 20 $/ton disposed Wastewater treatment 1.5 $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $55 to $550 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wre-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $9 to $84 per scfm Typical value is $34 per scfm O&M Costs: Range from $6 to $27 per scfm Typical value is $13 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for fabric filters (EPA, 1998a). O&M costs were calculated for three model plants with flow rates of 25, 75 and 150 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 4.0 grains per cubic feet. The operating time was assumed to be 8760 hours per year. An average bag cost was estimated using the costs for standard bag types. Capital recovery for the periodic replacement of bags was included in the O&M cost of the bags using a bag life of 2 years (EPA, 1998a). The following assumptions apply to the cost of utilities and disposal: Electricity price 0.0671 $/kW-hr Compressed air 0.25 $/1000scf Dust disposal 25 $/ton disposed Document No. 05.09.009/9010.463 III-1177 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Note: All costs are in 1998 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $53 to $337 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $148 per ton PM10 reduced. (1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) Document No. 05.09.009/9010.463 III-1187 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials.

Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to Document No. 05.09.009/9010.463 III-1188 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

Capital and operating costs are generally higher due to noncorrosive materials requirements, increased water usage, and treatment and disposal of wet effluent. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001).

The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1990). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001).

All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year.

The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-l 191 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wire-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

(1998$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: The cost estimates assume a conventional design under typical operating conditions. The costs do not include any auxiliary equipment (EPA, 2000). The capital cost for the reverse-jet cleaned fabric baghouse is based on information provided by a Document No. 05.09.009/9010.463 III-1195 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES manufacturer (EPA, 2000). The capital cost includes only the purchased equipment cost. Costs are primarily based on volumetric flow rate and the amount of PM in the waste stream. In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex streams are not reflected in the estimates. For these systems, the capital cost could increase by as much as 40% and the O&M cost could increase by as much as 5%. (EPA, 2000) In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Reverse-air cleaning is a popular filter cleaning method as it has been used extensively and improved over the years. It is a gentler but sometimes less effective clearing mechanism than mechanical shaking. Reverse-air cleaning is performed by forcing clean air through the filters in the opposite direction of the dusty gas flow. The change in direction of the gas flow causes the bag to flex and crack the filter cake allowing for internal cake collection (EPA, 2000). The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

Improved monitoring in this case means increasing the monitoring frequency of electrostatic precipitators, scrubbers, and fabric filters from once per day to four times per hour, with no change in monitoring technique. RTI's improved monitoring frequency analysis evaluates each scenario for four different excess emission rates (i.e., the sources limit their excess emissions to x percent after the improved monitoring method is applied). The most cost-effective scenarios are those where the source is able to limit excess emissions to less than one percent. The cost effectiveness of this measure is based on a case where the excess emissions are limited to 0.46 percent. The RTI memo (Barr and Schaffner) offers two methods for estimating emission reductions from an NEI baseline. These are labeled the original calculation method, and an alternative calculation method.

For forestry burning, increasing the fuel moisture will decrease particulate emissions by decreasing the amount of fuel burned. This control is applicable to prescribed burning for forest management.

Costs vary based on the current burn schedule and method, along with the type of land under consideration (federal versus private). Based on the emission factor for PM10 emissions and the 50 percent control efficiency, a $826-$3,500 PM10 cost per ton range (in 1986 dollars) is estimated. For PM10: (($38-$161 per acre) / (0.092 tons PM-10/acre)) * ((1 ton emitted) / (0.50 ton reduced)) = $826-$3,500 per ton PM10 reduced (in 1986 dollars) Because this measure entails work practice changes, costs were converted to 1990 dollar terms using the 1986-1990 producer price index for employment costs (BLS, 1994). For PM10: $826-$3,500 per ton in 1986 dollars * 1.21 = $999-$4,235 per ton PM10 reduced (in 1990 dollars) The midpoint of these cost ranges was used in the analysis, PM10 costs are estimated at $2,617 per ton.

The costs here are based on the Clement Falls, Oregon education and advisory program and mandatory curtailment program. It is assumed that the costs are proportional to population. This results in a per capita cost of $0.79 for the education and advisory program, $0.01 for the forecasting system, and $0.02 for the mandatory curtailment program. The cost per ton reduced varies depending on the assumed fraction of Phase II woodstoves versus conventional woodstoves. Here the percentage of Phase II stoves is assumed to be 72% (Pechan, 1997).

Comments: Status: Demonstrated Last Reviewed: 1997 Additional Information: Chemical stabilization was investigated as a supplemental control option to hot asphalt paving for urban areas. For rural areas, chemical stabilization was evaluated as an alternative to watering (Pechan, 1995). The control application parameters that affect the control efficiency of chemical dust suppressants are application intensity, application frequency, dilution ratio and application procedure (EPA, 1986). Other factors that influence the control efficiency are the silt content of the soil, weather conditions and the weight and level of traffic. An increase in vehicle weight and speed serves to accelerate the decay in efficiency for chemical suppression.

Hot asphalt paving is based on the use of paving materials which meet RACT requirements and thereby do not emit VOCs. Hot asphalt paving was selected as the control option for urban areas. This control measure applies to all unpaved roads classified under SCC 2296000000.

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. In dry ESPs, the collectors are knocked by various mechanical means to dislodge the particulate, which slides downward into a hopper. This control applies to electricity generation sources powered by pulverized dry-bottom and bituminous/subbituminous coal.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan, 2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996).

The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles Document No. 05.09.009/9010.463 III-1213 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999). The particulate-bound form of mercury can be readily captured in the particulate matter (PM) control devices, e.g., fabric filters (FF). Also, gaseous mercury (both HgO and Hg 2+) can potentially be adsorbed on fly ash and subsequently be collected on a PM device. However, the level of this adsorption depends on the speciation of mercury, the flue gas concentration of fly ash, and many other factors. Average mercury capture efficiencies of PM post-combustion control measures for coal-fired utility boilers are based on research data from National Risk Management Research Laboratory (EPA, 2002). Control efficiencies are based on a series of tests conducted on a several plants throughout the United States. The background documents to National Risk Management Research Laboratory Study (EPA, 2002) also provided estimates of control efficiencies of Hg species for a limited number of tests References: EPA, 1996: U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, "OAQPS Control Cost Manual," Fifth Edition, EPA 453/B-96-001, Research Triangle Park, NC.

In general, a small unit controlling a low pollutant levels will not be as cost effective as a large unit controlling a high pollutant levels. (EPA, 2000) Pollutants requiring a high level of control or the fabric filters to be constructed of special materials will increase the costs of the system (EPA, 1998a). The additional costs for controlling complex waste streams are not included in the estimates. For these systems, the capital cost could increase by as much as 30% and the O&M cost could increase by as much as 7%. In a fabric filter, flue gas is passed through a tightly woven or felted fabric, collecting PM by sieving and other mechanisms. Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Mechanical shaking is a popular cleaning method because it is both simple and effective. In typical operation, dusty gas enters an inlet pipe to the fabric filter and very large particles are removed using a baffle plate fall into the hopper. The gas stream is drawn from beneath a cell plate in the floor and into the filter bags (EPA, 2000). The gas proceeds from the inside to the outside of the filter bags. The particles collect on the inside of the bags, forming a filter cake. In mechanical shaking units, the tops of bags are attached to a shaker bar, moved briskly (usually in a horizontal direction) to clean the bags. The shaker bars are operated by mechanical motors or by hand (EPA, Document No. 05.09.009/9010.463 III-1216 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES 1998b).. Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5). Fabric filters may be good candidates for collecting fly ash from low-sulfur coals or containing high unburned carbon levels and are relatively difficult to collect with electrostatic precipitators.

When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 2000). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996).

Fabric filters may be in the form of sheets, cartridges, or bags, with many individual filter units together in a group. Bags are the most common type of filter. The dust cake that forms on the filter from the collected PM can significantly increase collection efficiency. (EPA, 2000) Pulse-jet cleaning of fabric filters is a relatively new type of fabric filter, as they have only been used for the past 30 years. This cleaning mechanism has grown in popularity because it can treat high dust loadings, operate at constant pressure drop, and occupy less space than other types of fabric filters (EPA, 2000). Particulate-laden gas flows into the bag. The gas flows from the outside to the inside of the bags, and then out the gas exhaust. The particles collected on the outside drop into a hopper below the fabric filter (EPA, 1998b). Document No. 05.09.009/9010.463 III-1219 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES During pulse-jet cleaning, a short burst of high pressure air is injected into the bags (EPA, 1998b). The pulse is blown through a venturi nozzle at the top of the bags and establishes a shock wave that continues onto the bottom of the bag. The wave flexes the fabric dislodging the dust cake. There are several unique attributes of pulse-jet cleaning. The cleaning pulse is very brief allowing the flow of dusty gas to continue during cleaning. The bags not being cleaned continue to filter, taking on extra duty from the bags being cleaned (EPA, 2000). Pulse-jet cleaning is more intense and occurs with greater frequency than the other fabric filter cleaning methods. The cleaning dislodges nearly all of the dust cake each time the bag is pulsed. Pulse-jet filters, as a result, do not rely on a dust cake to provide filtration. Felted (non-woven) fabrics are used in these types of filters because they do not require a dust cake. Also it has been found that woven fabrics used with pulse- jet cleaning leak dust after they are cleaned (EPA, 1998b). Since bags cleaned by the pulse-jet method do not need to be isolated for cleaning, pulsejet cleaned fabric filters do not need extra compartments to maintain adequate filtration during cleaning. Also, because of the intense and frequent nature of the cleaning, they can treat higher gas flow rates with higher dust loadings. Consequently, fabric filters cleaned by the pulse-jet method can be smaller than other filters in the treatment of the same amount of gas and dust, making higher gas-to-cloth ratios achievable (EPA, 1998b). Fabric filters are useful for collecting particles with resistivities either too low or too high for collection with electrostatic precipitators. Fabric filters are useful in controlling particulate matter less than or equal to 10 micrometers (|jm) in diameter (PM10) and particulate matter less than or equal to 2.5 |jm in diameter (PM2.5).

Document No. 05.09.009/9010.463 III-1222 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES The most common design is to have separate compartments within the fabric filter so that each can be isolated and cleaned separately while the others continue to treat the dusty gas. There are several methods of reversing the flow through the filters. One method of providing the reverse flow is by the use of a fan or cleaned gas from other compartments. Reverse-air cleaning only used alone in cases where the dust releases easily from the fabric. In many instances, reverse-air is used along with shaking, pulsing or sonic horns (EPA, 1998b).

The fixed annual charge for taxes, insurance and administrative Document No. 05.09.009/9010.463 III-1229 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES costs was estimated as 4 percent of the total capital investment (EPA, 1999). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001). The range of high and low capital costs and O&M costs presented in the fact sheets were calculated based on the OAQPS Control Cost Manual and associated spreadsheets (EPA, 1996). The low costs in the ranges below are representative of equipment sized based on the maximum flow rate recommended in the cost manual, with no exotic materials. The high costs in the ranges below are representative of equipment sized based on the minimum flow rate recommended in the cost manual, with not exotic materials. No optional pre- or post treatment equipment costs are included. Capital Costs: Range from $15 to $50 per scfm Typical value is $27 per scfm O&M Costs: Range from $4 to $40 per scfm Typical value is $16 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1996). O&M costs were calculated for three model plants with flow rates of 200 and 500 thousand acfm and 1 million acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Dust disposal 25 $/ton disposed Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $40 to $250 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $110 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Document No. 05.09.009/9010.463 III-1230 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Another factor in the performance of ESPs is the resistivity of the collected material. All the ion current must pass through the collected layer to reach the ground plates. This creates an electric field in the layer, and it can become large enough to cause electrical breakdown. When this occurs, new ions of the wrong polarity are injected into the wire-plate gap reducing the charge on the particles, which may cause sparking. This condition is called "back corona." When this happens the collection ability of the unit is reduced. At low resistivities the particles are held on the plates so loosely that reentrainment levels are much higher. Hence, care must be taken in measuring or estimating resistivity because it is strongly affected by such variables as temperature, moisture, gas composition, particle composition, and surface characteristics (EPA, 1999). Dusts with high resistivities are also not well-suited for collection in dry ESPs. These particles are not easily charged nor easily collected. High-resistivity particles form ash layers with very high voltage gradients on the collecting electrodes lead to back corona, reducing the charge on particles and lowering collection efficiency. Fly ash from the combustion of low-sulfur coal typically has a high resistivity, and thus is difficult to collect using dry ESPs (EPA, 1999).

An ESP uses electrical forces to move particles in an exhaust stream onto collector plates. Electrodes in the center of the flow are maintained at high voltage and generate an electrical field forcing particles to the collector walls. Wet ESPs use a stream of water, in place of rapping mechanisms, to dislodge particulate from the plates and into a sump.. This control measure applies wood pulp and paper processing and production operations.

Capital and operating costs are generally higher due to noncorrosive materials requirements, increased water usage, and treatment and disposal of wet effluent. When stack gas flow rate data was available, the costs and cost effectiveness were calculated using the typical values of capital and O&M costs. When stack gas flow rate data was not available, default typical capital and O&M cost values based on a tons per year of PM10 removed were used (Pechan,2001). Document No. 05.09.009/9010.463 III-1232 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Total annualized costs were determined by adding the annualized O&M costs, fixed capital recovery charges, and a fixed annual charge for taxes, insurance and administrative costs. The fixed annual charge for taxes, insurance and administrative costs was estimated as 4 percent of the total capital investment (EPA, 1990). Total installed capital costs were annualized using a capital recovery factor, with is based on a 7 percent discount rate and the expected life of the control equipment (20 years) (Pechan, 2001).

Capital Costs: Range from $30 to $60 per scfm Typical value is $40 per scfm O&M Costs: Range from $6 to $45 per scfm Typical value is $19 per scfm O&M Cost Components: The percentages of each O&M cost component were developed using EPA's cost-estimating spreadsheet for ESP (EPA, 1999). O&M costs were calculated for three model plants with flow rates of 10, 15 and 20 thousand acfm. The average percentage of the total O&M cost was then calculated for each O&M cost component. All the model plants were assumed to have a dust loading of 6.0 grains per cubic feet. The operating time was assumed to be 8640 hours per year. A water flow rate for the ESP was assumed to be 5 gal/min per thousand acfm. The following assumptions apply to the cost of utilities and disposal: Electricity price 0.067 $/kW-hr Process water price 0.20 $/1000gal Dust disposal 20 $/ton disposed Wastewater treatment 1.5 $/ thousand gal treated Note: All costs are in 1995 dollars. Cost Effectiveness: When stack flow is available the cost effectiveness varies from $55 to $550 per ton PM10 removed, depending on stack flow. The default cost effectiveness value, used when stack flow is not available, is $220 per ton PM10 reduced. (1995$) Comments: Status: Demonstrated Last Reviewed: 2001 Document No. 05.09.009/9010.463 III-123 3 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES Additional Information: Costs can be substantially higher than in the ranges shown for pollutants which require an unusually high level of control, or which require the ESP to be constructed of special materials such as titanium (EPA, 1999). In most cases, smaller units controlling a low concentration waste stream will not be as cost effective as a large unit cleaning a high pollutant load flow (EPA, 1998). In the wire-plate ESP, the gas flows around vertical, metal plates. The electrodes are long, weighted wires hanging between the plates. The voltage applied to the electrodes causes the gas between the electrodes to break down, known as a "corona." The electrodes are most often given a negative polarity because a negative corona supports a higher voltage than a positive corona. Certain types of losses affect control efficiency. The dislodging of the accumulated layer also projects some of the particles back into the gas stream. These particles are processed in later sections of the ESP, but the particles from the last section have no chance to be recaptured. Due to the space needed at the top of the ESP for nonelectrified components, part of the stream may flow around the charged zones. This is called "sneakage" and places an upper limit on the collection efficiency of the ESP. Anti-sneakage baffles are used to force the sneakage flow to mix with the main gas stream for collection in later sections (EPA, 1998). Wire-Plate Type Wet ESPs require a source of wash water near the top of the collector plates. This wash system replaces the rapping mechanism used by dry ESPs. The water flows with the collected particles into a sump from which the fluid is pumped or drained. A portion of the fluid may be recycled to reduce the total amount of water required. The remainder is pumped into a settling pond or passed through a dewatering stage, with subsequent disposal of the sludge (AWMA, 1992). Unlike dry ESPs, resistivity of the collected material is not a major factor in performance. Because of the high humidity in a wet ESP, the resistivity of particles is lowered, eliminating the "back corona" condition. The frequent washing of the plates also limits particle buildup on the collectors (EPA, 1998). For wet ESPs, the handling wastewaters must be considered (EPA, 1999). For simple systems with innocuous dusts, water with particles collected by the ESP may be discharged from the ESP system to a solids-removing clarifier. More complicated systems may require skimming and sludge removal, clarification in dedicated equipment, pH adjustment, and/or treatment to remove dissolved solids. Recirculation of treated water to the ESP may approach 100 percent (AWMA, 1992).

Cost Effectiveness: The cost effectiveness is variable depending on stack flow rate in cubic feet per minute. Comments: Status: Demonstrated Last Reviewed: 2004 Additional Information: The contact process is used to produce sulfuric acid from waste gas which contains S02. First, the waste gas must be pretreated, which usually involves dust removal, cooling, and scrubbing for further removal of particulate matter and heavy metals, mist, and moisture. After pretreatment, the gas is heated and passed through a catalytic converter (platinum mass units or units containing beds of pelletized vanadium pentoxide) to oxidize the S02 to S03. The exothermic, reversible oxidation reaction results in a conflict between high equilibrium conversions at lower temperatures and high reaction rates at high temperatures. Because of this, the gas is passed between the catalyst and two or three different heat exchangers in order to achieve conversion of S02 to S03 of about 92.5 to 98 percent. The gas leaving the final catalyst stage is cooled and introduced to an absorption tower by a stream of strong (98 to 99 percent) acid, where the S03 reacts with water in the acid to form additional sulfuric acid. Dilute sulfuric acid or water is added to the recirculating acid to maintain the desired concentration (EPA, 1981; EPA, 1997). The double-contact, or double-absorption, process for making sulfuric acid from waste gas containing S02 is essentially the same as the single-contact process with the addition of an interpass absorption tower. The waste gas is cleaned and dried as in the single-contact process before entering the process. Upon leaving the second or third catalyst bed, depending upon the process, the gas is cooled and introduced to a packed-bed, counter-current absorption tower where it contacts 98 to 99 percent sulfuric acid. After the absorbing tower, the gas is reheated and passed to the third or fourth catalyst bed, where approximately 97 percent of the remaining S02 is converted to S03 and passed to the final absorption tower for conversion to sulfuric acid as in the single-contact process. No cost data were available for either single- or double-contact sulfuric acid plants controls (EPA, 1981; EPA, 1997).

Because of this, the gas is passed between the catalyst and two or three different heat exchangers in order to achieve conversion of S02 to S03 of about 92.5 to 98 percent. The gas leaving the final catalyst stage is cooled and introduced to an absorption tower by a stream of strong (98 to 99 percent) acid, where the S03 reacts with water in the acid to form additional sulfuric acid. Dilute sulfuric acid or water is added to the recirculating acid to maintain the desired concentration (EPA, 1981; EPA, 1997). The double-contact, or double-absorption, process for making sulfuric acid from waste gas containing S02 is essentially the same as the single-contact process with the addition of an interpass absorption tower. The waste gas is cleaned and dried as in the single-contact process before entering the process. Upon leaving the second or third catalyst bed, depending upon the process, the gas is cooled and introduced to a packed-bed, counter-current absorption tower where it contacts 98 to 99 percent sulfuric acid. After the absorbing tower, the gas is reheated and passed to the third or fourth catalyst bed, where approximately 97 percent of the remaining S02 is converted to S03 and passed to the final absorption tower for conversion to sulfuric acid as in the single-contact process. No cost data were available for either single- or double-contact sulfuric acid plants controls (EPA, 1981; EPA, 1997).

The costs are based on stack flowrate in cubic feet per minute. Cost equations for dual absorption: Capital cost = $990,000 + $9,836 * Flowrate Operating cost = $75,800 + $12.82 * Flowrate Equipment Life in Years = Equiplife = 15 years Interest Rate = I = 7% Capital Recovery Factor: CRF = [ i (1 + i) A Equiplife ] / [ ((1 + i )A Equiplife) -1 Annual cost = (Capital cost * CRF) + O&M cost O&M Cost Components: The O&M cost components for dual absorbtion are based on two model plants with sulfur intake of 750 tons per day and 1,500 tons per day (EPA, 1985).

Cost Effectiveness: The cost effectiveness is variable depending on stack flow rate in cubic feet per minute. Comments: Status: Demonstrated Last Reviewed: 1999 Additional Information: The contact process is used to produce sulfuric acid from waste gas which contains S02. First, the waste gas must be pretreated, which usually involves dust removal, cooling, and scrubbing for further removal of particulate matter and heavy metals, mist, and moisture. After pretreatment, the gas is heated and passed through a catalytic converter (platinum mass units or units containing beds of pelletized vanadium pentoxide) to oxidize the S02 to S03. The exothermic, reversible oxidation reaction results in a conflict between high equilibrium conversions at lower temperatures and high reaction rates at high temperatures. Because of this, the gas is passed between the catalyst and two or three different heat exchangers in order to achieve conversion of S02 to S03 of about 92.5 to 98 percent. The gas leaving the final catalyst stage is cooled and introduced to an absorption tower by a stream of strong (98 to 99 percent) acid, where the S03 reacts with water in the acid to form additional sulfuric acid. Dilute sulfuric acid or water is added to the recirculating acid to maintain the desired concentration (EPA, 1981; EPA, 1997). The double-contact, or double-absorption, process for making sulfuric acid from waste gas containing S02 is essentially the same as the single-contact process with the addition of an interpass absorption tower. The waste gas is cleaned and dried as in the single-contact process before entering the process. Upon leaving the second or third catalyst bed, depending upon the process, the gas is cooled and introduced to a packed-bed, counter-current absorption tower where it contacts 98 to 99 percent sulfuric acid. After the absorbing tower, the gas is reheated and passed to the third or fourth catalyst bed, where approximately 97 percent of the remaining S02 is converted to S03 and passed to the final absorption tower for conversion to sulfuric acid as in the single-contact process. No cost data were available for either single- or double-contact sulfuric acid plants controls (EPA, 1981; EPA, 1997).

Comments: Status: Demonstrated Last Reviewed: 1999 Additional Information: FGD scrubbers can be either wet or dry systems. In wet systems, a liquid sorbent is sprayed into the flue gas in an absorber vessel. Limestone and lime-based reagents are most frequently used in scrubbers in the United States (EPA, 2002). Dry and semi-dry FGD systems include spray dryers, and dry injection into a duct or a combustion zone. The contact process is used to produce sulfuric acid from waste gas which contains S02. First, the waste gas must be pretreated, which usually involves dust removal, cooling, and scrubbing for further removal of particulate matter and heavy metals, mist, and moisture. After pretreatment, the gas is heated and passed through a catalytic converter (platinum mass units or units containing beds of pelletized vanadium pentoxide) to oxidize the S02 to S03. The exothermic, reversible oxidation reaction results in a conflict between high equilibrium conversions at lower temperatures and high reaction rates at high temperatures. Because of this, the gas is passed between the catalyst and two or three different heat exchangers in order to achieve conversion of S02 to S03 of about 92.5 to 98 percent. The gas leaving the final catalyst stage is cooled and introduced to an absorption tower by a stream of strong (98 to 99 percent) acid, where the S03 reacts with water in the acid to form additional sulfuric acid. Dilute sulfuric acid or water is added to the recirculating acid to maintain the desired concentration (EPA, 1981; EPA, 1997). The double-contact, or double-absorption, process for making sulfuric acid from waste gas containing S02 is essentially the same as the single-contact process with the addition of an interpass absorption tower. The waste gas is cleaned and dried as in the single-contact process before entering the process. Upon leaving the second or third catalyst bed, depending upon the process, the gas is cooled and introduced to a packed-bed, counter-current absorption tower where it contacts 98 to 99 percent sulfuric acid. After the absorbing tower, the gas is reheated and passed to the third or fourth catalyst bed, where approximately 97 percent of the remaining S02 is converted to S03 and passed to the final absorption tower for conversion to sulfuric acid as in the single-contact process. No cost data were available for either single- or double-contact sulfuric acid plants controls (EPA, 1981; EPA, 1997).

The cost equations used in this analysis are based on cost equations developed to scale costs to smaller or larger boilers than the model plant (EPA, 2002). Model plants were considered to have boiler design capacities of 500 MW. Several simplifying assumptions were made in developing the costing parameters used for this analysis. A capacity utilization factor of 65 percent were assumed, as well as a 7-percent discount rate and 15-year lifetime of the repowering equipment. A control efficiency of 99 percent was assumed for repowering on all utility boiler fuel types (EPA, 1998).

Comments: Status: Demonstrated Last Reviewed: 2003 Additional Information: There are several repowering options available to the utilities. Examples include coal to combined cycle and coal to integrated gasification combined cycle (IGCC). Repowering improves power plant efficiencies and implies significant waste reduction from the new systems relative to the performance of technologies in widespread commercial use as of November 1990 (EPA, 1994). For example an existing coal-fired plant can convert into a natural gas-combined cycle plant, resulting in higher plant efficiency and yield lower NOx, PM and S02 emissions. Typical repowering entails steps in which the coal handling system and the boiler are replaced with new combustion turbines and a heat recovery boiler. The only significant part of the plant that is maintained is the original turbine generator. However, many of the new combined-cycle plants are packaged systems and because many older coal-fired plants were custom built, they do not always come in standard sizes or configurations. If such facilities are to be repowered, additional work is required to integrate the system components and this could be very costly. The IGCC is a repowering option that required extensive gasification equipment to generate synthetic gas from coal in order to feed the gas turbines. IGCC unit installation could also result in significant reduction of Hg. IGCC plants offer the capability of removing the Hg from the compressed syngas prior to combustion where the gas volume treated is much less than the low pressure, post-combustion flow volume (Parsons, 2002). The predominant form of Hg in the IGCC syngas is elemental and removing prior to combustion is considered to be far more cost-effective than controlling emissions from the exhaust.

S02 emissions can be reduced by switching from high-sulfur to low-sulfur coal. However, the emission reduction levels will depend on the types of coal that are being switched (DOE, 1997). This control is applicable to electricity generating sources powered by pulverized dry- bottom and bituminous/subbituminous coal.

Capital costs may include new storage and distribution systems as well as modifications to the combustion operations. Switching from bituminous to a subbituminous coal can also lead to an increase in the particulate matter emissions, requiring further investments on controls. The costs detailed here are based on fuel switching and blending from high-sulfur content bituminous to low-sulfur bituminus and to subbituminous coal. Cost Effectiveness: Cost effectiveness varies depending on the ranks of the old and new fuels and is estimated based on the emission factors. The cost effectiveness ranged from $113 to $167 per ton S02 reduced. The cost effectiveness value used in AirControlNET is $140 per ton S02 reduced. All costs are in 1995 dollars. Comments: Status: Demonstrated Last Reviewed: 2003 Document No. 05.09.009/9010.463 III-1331 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES Additional Information: Coal contains noncombustible minerals and mineral oxides that are collectively referred to as ash. In terms of fuel composition, ash content of fuel is the major factor in determining total suspended particle emissions (TSP). The higher the ash content, the higher the amount of TSP emitted from combustion. Fuel substitution can impact TSP emissions leading to their reduction. It should be noted that if the new coal has a significantly lower energy content there may be an increase in TSP emissions due to the higher amounts of coal needed to achieve the same energy output (DOE, 1994). While effective in lowering S02 and PM emissions, the practice of switching to a low-sulfur content can lead to reduced collection efficiency of electrostatic precipitators which are the most common method of particulate controls for utility boilers. Lowering the flue gas sulfur content increases the fly ash resistivity and subsequently lowers the overall particulate matter collection efficiency at these post-combustion units. Lower particle collection efficiency in coal fired boilers leads to a lower mercury removal efficiency. Therefore this form of fuel switching, from high-sulfur to low-sulfur coal, is not a viable option for controlling mercury and will not be discussed in detail.

Disposal of the liquid wastes formed during these processes can be difficult and/or expensive and are reflected in the operating and maintenance costs (ERG, 2000). The cost of coal washing can vary significantly based on characteristics of the raw coal and the types of processes involved, as well as the plant capacity. The capital costs for coal washing facilities range form $12 to $16 per ton of coal. Operating costs range from $3.17 to $4.40 per ton for systems that feature high BTU recovery, high levels of ash rejection (40-50%) and 20 to 50% sulfur removal (SIU, 1997). Cost Effectiveness: Cost effectiveness varies based on the characteristics of the raw coal, washing processes and plant capacity from $70 to $563 per ton S02 reduced. The average cost used in AirControlNET is $320 per ton S02 reduced. All costs are in 1997 dollars.

Coal washing is a pre-combustion process which is used to remove ash and sulfur from the coal. During this process rock, clay and other minerals can be separated from the coal in a liquid medium. Coal washing is a process that is applied before delivery to the utility plant. In some cases, however, coal is passed through a drying step at the power plant before loading into the boiler. Coal washing can also be an effective method for removing Hg. Estimated overall reductions at national levels were reported to be 21% (EPA, 1997). Coal washing can separate minerals from coal through the difference in specific gravities of the constituents or by surface-based floatation. Two types of coal washing methods can be performed on intermediate and coarse coal: 1. Gravity concentration method: Technologies that use this method include jigs, cyclones, shaking tables and Reichert cones. A significant portion of coal preparation plants use jigs to separate coal from non-coal material. The majority of jigs process wet coal, but some pneumatic jigs are also used. Like jigs, the shaking tables, cyclones and Reichert cones rely on water flow and motion of the equipment to separate more dense impurities from the lighter coal (EPA, 2000). 2. Dense medium separation method: This process usually takes place in large open tanks, with the pulverized magnetite (Fe304) in water used as the preferred medium for separation. The density of the medium is adjusted to lie between the dense inorganic matter and the less dense organic combustible fraction of coal. As a result, the inorganic material sinks to the bottom of the tank and the organic coal floats to the top where it is skimmed from the tank. Fine coal cleaning involves chemical conditioning of the coal followed by flotation to recover clean coal. Depending on the characteristics of the coal, some mines may perform fine coal conditioning using lime, sodium carbonate, sodium hydroxide or sulfuric acid. Conditioning is used to adjust pH, to facilitate the flotation process (EPA, 2000).

The cost equations used in this analysis are based on cost equations developed to scale costs to smaller or larger boilers than the model plant (EPA, 1998)). Model plants were considered to have boiler design capacities of 500 MW. Several simplifying assumptions were made in developing the costing parameters used for this analysis. A capacity utilization factor of 65 percent was assumed, as well as a 7-percent discount rate and 15-year lifetime for the scrubber. A control efficiency of 90 percent was assumed for scrubbers on all utility boiler fuel types. The fuel sulfur content level for these equations is 3% sulfur.

Comments: Status: Demonstrated Last Reviewed: 2001 Additional Information: In wet systems, a liquid sorbent is sprayed into the flue gas in an absorber vessel. Limestone and lime-based reagents are most frequently used in scrubbers in the United States (EPA, 2002a). Studies have shown that Wet FGD can also be effective in controlling mercury emissions. The ionic mercury compounds in coal flue gases are water-soluble and can be captured by WFGD scrubbers. In Wet FGD, the soluble gaseous Hg is mixed with the water-based scrubbing liquid and then removed from the flue stream with the disposed scrubbing solution. Wet Flue Gas Desulfurization scrubbers use a caustic slurry, typically water and limestone or water and lime as S02 scrubbing solutions. Document No. 05.09.009/9010.463 III-1336 Report ------- AT-A-GLANCE TABLE FOR UTILITY SOURCES The level of mercury capture in Wet FGD systems depends on the relative level of Hg2+ present in the flue gas that enters the system. The gaseous HgO is insoluble in water and does not dissolve in such slurries. The majority of Hg2+ species in the flue gas are soluble in water. After they are dissolved in the FGD solution, these mercury compounds are believed to react with dissolved sulfides from the flue gas, such as H2S, to form mercuric sulfide (HgS), which precipitates from the liquid solution as sludge. The level of Hg 2+ that enters the Wet FGD system depends on the flue gas as well as the upstream control system (e.g., a FF and SCR, used for PM and NOx control, respectively oxidizes the elemental mercury). A PM control device always precedes a wet Wet FGD scrubber. Four types of PM control devices are commonly used upstream of the Wet FGD systems: FFs, CS-ESPs, HS-ESPs, and PM scrubbers (PS). In systems with a FF upstream of the Wet FGD system, an increase in mercury reduction is observed across the Wet FGD system due to the oxidization of elemental mercury that occurs on the fabric filter cake. Units equipped with FF+WFGD achieve the highest Hg reduction followed by units with CS-ESP, HS-ESP, and PS. Units with HS-ESPs operate at temperatures where the oxidization and capture of Hg is limited; therefore, a lower mercury reduction across the system is achieved (Massachusetts, 2002). Mercury control efficiencies of existing post-combustion controls used for coal-fired electric utility boilers were examined based on a series of tests that were conducted as part of a research and development study by the National Risk Management Research Laboratory for EPA (EPA, 2002b). Table 3 shows the overall mercury control efficiencies for the S02 co-controls. Note: the control efficiencies are provided for a combined unit operations (WFGD plus a PM control device).

The rule sets maximum allowable VOC content limits for 55 different categories of AIM coatings, and affects the manufacturers and importers of the coating products. VOC content limits defined in the national rule took effect on September 11, 1999. Manufacturers of FIFRA - regulated coatings had until March 10, 2000 to comply. Sixty-four percent of the products included in the 1990 industry survey meet the VOC content limits in this rule and, therefore, there will be no costs to reformulate these products. The manufacturer of a product that does not meet the VOC content limits will be required to reformulate the product if it will continue to be marketed, unless the manufacturer chooses to use an alternative compliance option such as the exceedance fee or tonnage exemption provision. In AirControlNET, this control measure only affects architectural coatings.

Industry representatives estimated the level of effort required by a representative firm to research and develop a new prototype coating to be 2.5 scientist-years over a 3-year time period. EPA calculated an annualized cost of $17,772 per reformulation (1991 dollars) based on an assumed cost of $100,000 per scientist-year as amortized over an assumed repopulation cycle of 2.5 years. The estimated average cost to reformulate a product was $87,000. The total estimated national cost of the AIM Coating Federal rule is 25.6 million per year (1991 dollars). Cost Effectiveness: EPA estimated emission reductions of 106,000 tons of VOC per year so that the cost effectiveness is computed as $228 per ton VOC reduction (1990$).. Comments: The EPA did not account for potential cost differences for reformulating coatings to Document No. 05.09.009/9010.463 III-1347 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES various content limits. Instead, EPA assumed that a reformulation has a certain cost to manufacturers regardless of the target content limit, or the anticipated VOC reduction (Ducey, 1997). Status: Demonstrated Last Reviewed: 1998 Additional Information: In its analysis of the proposed federal rule, EPA assumed that the cost of product reformulation would bring the VOC content limit for each noncompliant coating down to the level of the standards. The EPA, however, noted the likelihood that some manufacturers will likely reduce the VOC content of their coatings to levels significantly below the limits in the rule (EPA, 1996). The at-the-limit assumption, therefore, likely results in emission reductions being understated. In its cost analysis, insufficient data were available for EPA to distinguish reformulation costs between different coating types (i.e., the reformulation cost for flat paints is equal to the reformulation cost for all other affected paint types). The EPA noted the likelihood of reformulation costs varying from product to product (EPA, 1995). References: Ducey, 1997: E.

The SCAQMD estimated that manufacturers would use an acetone formulation with an associated cost of $2 per gallon to meet the proposed 550 grams per liter (g/L) VOC limit for lacquers. For flats, South Coast estimated a zero cost for complying with the near-term 100 g/L limit since most flats sold in California are already in compliance with this limit. For traffic and multi-color coatings, the SCAQMD estimated that a cost savings was likely to be associated with reformulation due to a decrease in the cost of input materials. (The estimated magnitude of the savings is not documented in the SCAQMD report.) Costs were estimated by multiplying the cost per gallon data to total gallons sold. The resulting weighted average cost effectiveness value was converted to 1990 dollars using the 1995:1990 producer price index for Standard Industrial Classification (SIC) code 2851 (Paints and Allied Products). Because capital cost information was not available, capital costs were not estimated for this analysis.

These limits apply to any coating applied to motor vehicles. Emissions from auto body refinishing can be classified in three categories (and percentage contribution): surface preparation (1.6%), coating application (91.0%), and spray gun cleaning (7.4%). Affected SCC: 2401005000 Auto Refinishing: SIC 7532, Total: All Solvent Types Pollutant(s) PM10 PM2.5 EC OC NOx VOC S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 47% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: Cost effectiveness was derived from BARCT limits using a weighted average of costs from surface preparation product limits and spray gun cleaners (Pechan, 1994). Costs for reformulating preparation products are estimated to be $900 per ton for additional equipment to facilitate longer drying times needed for these coatings. A savings of $900 per ton is documented for the use of spray gun cleaners due to the reduction in solvent usage. Cost Effectiveness: The cost effectiveness used in AirControlNET is $750 per ton VOC reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 1994 Additional Information: The low-VOC coatings that meet the BARCT limits require significantly longer drying times, and may require the purchase of additional equipment (e.g. heating lamps) in areas with weather conditions unlike California's (Pechan, 1994). Surface preparation emissions may be reduced through the use of low VOC-preparation products. These products generally consist of more detergents (and less solvent) and must remain on the surface longer and require additional rubbing for thorough removal of dirt, grease and old paint. Emissions from coating applications can be reduced through low VOC content coatings (high solids Document No. 05.09.009/9010.463 III-13 66 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES or waterborne coatings) and/or increased transfer efficiency (e.g. high volume, low pressure spray equipment). Equipment cleaning emissions can be reduced through the use of gun cleaners which either recirculate solvent or minimize evaporation. References: Pechan, 1994: E.H.

This FIP rule requires the use of low-VOC coatings or the use of an emission control system, and a transfer efficiency for all coating application equipment equivalent to that of high-volume, low-pressure (HVLP) spray equipment (Radian, 1994). The FIP rule applies to all facilities that apply coatings of any kind to motor vehicles and mobile equipment for the purpose of on-site refinishing and modification. Affected facilities include auto body repair/paint shops, production auto body paint shops, new car dealer repair/paint shops, fleet operator repair/paint shops, custom-made car fabrication facilities, and truck body builders (Radian, 1994).

The SCAQMD Rule 1151 regulates emissions from solvent operations, however the FIP rule does not. To account for the difference in regulations, the cost is calculated as the difference between the total cost of SCAQMD Rule 1151 and the cost of solvent operations. The cost effectiveness was calculated based on an estimate of 26.4 tpd VOC reduced (Radian, 1994). Cost of Rule 1151: $201,100 per day Cost of Solvent Operations: $11,500 per day Difference = $189,600 per day Cost Effectiveness = Difference / Tons Reduced Per Day = $7,200 per ton VOC reduced Note: All costs are in 1990 dollars.

These incinerators use a catalyst to achieve very high control efficiencies at relatively low operating temperatures (320 to 650 °C). The BAAQMD control requirements affect only large, commercial bread bakeries, classified under SCC 2302050000. Affected SCC: 2302050000 Bakery Products, Total Pollutant(s) PM10 PM2.5 EC OC NOx VOC S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 40% from uncontrolled Equipment Life: 10 years Rule Effectiveness: 100% Penetration: 100% Cost Basis: Costs for catalytic incinerators were developed using a spreadsheet cost model provided by EPA. The spreadsheet model uses the procedures documented in the OAQPS Control Cost Manual for developing costs for catalytic incinerators (EPA, 1990). Oven parameters that were used in the spreadsheet model to calculate capital, operating and maintenance (O&M) costs, and cost effectiveness were provided by EPA (1992). Fixed annual costs for taxes, insurance, and administration were estimated as 4 percent of total installed capital costs. Capital recovery costs were estimated using a factor of 0.1424 (based on a 7 percent interest rate and 10-year equipment life) times total installed capital costs. The spreadsheet model was used to estimate costs as follows: Capital costs= $3,880 per ton VOC reduced O&M costs= $800 per ton VOC reduced The equipment costs in the spreadsheet model provided by EPA are in 1988 dollars. The costs were indexed to 1990 dollars using the 1988-1990 equipment cost indices for catalytic incinerators (M&S, 1991; EPA, 1995). Cost Effectiveness: The cost effectiveness used in AirControlNET is $1,470 per ton VOC reduced (1990$).

Comments: Status: Demonstrated Last Reviewed: 1996 Additional Information: The CARB plans to reduce VOC emissions from the consumer products category using three types of control measures: near-term, mid-term, and long-term measures. Near-term measures include VOC content limits for antiperspirants, Phase I consumer products, and Phase II consumer products. The CARB is implementing the near-term measures as follows: 1) Initial VOC limits for: Antiperspirants by 1993, Phase I consumer products by 1994, Phase II consumer products by 1995; 2) More stringent VOC content limits for: Antiperspirants by 1999, Selected Phase I products by 1996 and 1999, Selected Phase II products by 1997 and 1998. Some of CARB's standards were identified as technology-forcing because they cannot be met by manufacturers at the time of rule adoption, but can be met within the time-frame provided by the regulation. The CARB's mid-term controls apply to additional consumer products that are not affected by the near-term measures. These measures are to achieve an additional 25 percent reduction in overall VOC emissions from consumer products by 2005.

Comments: Status: Demonstrated Last Reviewed: 1997 Additional Information: This control measure proposes to reduce VOC emissions from electronic components manufacturing operations through the application of several control methods. These control methods include installation of add-on control equipment, material reformulations, and improved operating procedures. Such control methods are currently required for semiconductor manufacturing operations and are also expected to be applicable to this source category due to the similarity in Document No. 05.09.009/9010.463 III-13 84 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES operations. Add-on control devices such as carbon adsorption, and thermal and catalytic incinerators could be used to capture and/or eliminate organic compound emissions from the operation exhaust streams. In addition, development of low-VOC, high-solids content, and water-based formulations could provide another alternative for reducing VOC emissions from this source category. Further emission reductions could also be expected through adoption of improved procedures resulting in lower solvent usage and/or evaporation (SCAQMD, 1988). Assuming that the proposed control methods would have the same control efficiency as achieved in semiconductor manufacturing operations, implementation of this control measure is expected to be 70 percent efficient in reducing VOC emissions from this source category.

Consistent with the OAQPS Control Cost Manual, an interest rate of 7% was used to determine the capital recovery factor. Although the PTE is expected to have a life of 30 years, PTE costs were annualized over a 15 year period, representing the expected catalytic oxidizer life. Each PTE was assumed to capture 100% of all VOC emissions. All captured emissions were assumed to be vented to a catalytic thermal oxidizer achieving a 97% control efficiency. Therefore, the net VOC control efficiency is 97%. Year 1997 dollars were specified for cost calculations in the EPA background document for the printing and publishing industry. The EPA also evaluated costs based on the use of a thermal (non-catalytic) oxidizer; the annualized costs were higher than for the use of a catalytic oxidizer. Cost Effectiveness: The cost effectiveness is $1,343 per ton VOC reduction (1997$). The cost effectiveness is based on an annualized capital cost of $62,900 and an annual Document No. 05.09.009/9010.463 III-13 87 Report ------- AT-A-GLANCE TABLE FOR POINT SOURCES operation and maintenance (O&M) cost of $121,242 averaged over four model textile manufacturing plants.

Costs were estimated on a per- vehicle basis in all counties with no RFG in the base case. The number of vehicles was estimated by dividing the VMT by the average LDGV annual mileage accumulation rate. The annual costs for RFG is estimated assuming $0,043 per gallon (Pechan 2002) ($1997). Cost Effectiveness: The cost effectiveness of RFG varies greatly by county. Cost effectiveness for VOC ranged from $28,905,773 to $2,498 per ton. The average C-E for VOC is $25,093 per ton of VOC reduced (median is $16,656 per ton). All costs are $1997. Comments: In some cases this control produces a slight NOx disbenefit.

The rule sets maximum allowable VOC content limits for 55 different categories of AIM coatings, and affects the manufacturers and importers of the coating products. VOC content limits defined in the national rule took effect on September 11, 1999. Manufacturers of FIFRA - regulated coatings had until March 10, 2000 to comply. Sixty-four percent of the products included in the 1990 industry survey meet the VOC content limits in this rule and, therefore, there will be no costs to reformulate these products. The manufacturer of a product that does not meet the VOC content limits will be required to reformulate the product if it will continue to be marketed, unless the manufacturer chooses to use an alternative compliance option such as the exceedance fee or tonnage exemption provision. In AirControlNET, this specific control measure applies only to industrial maintenance coatings.

Industry representatives estimated the level of effort required by a representative firm to research and develop a new prototype coating to be 2.5 scientist-years over a 3-year time period. EPA calculated an annualized cost of $17,772 per reformulation (1991 dollars) based on an assumed cost of $100,000 per scientist-year as amortized over an assumed repopulation cycle of 2.5 years. The estimated average cost to reformulate a product was $87,000. The total estimated national cost of the AIM Coating Federal rule is 25.6 million per year (1991 dollars). Cost Effectiveness: EPA estimated emission reductions of 106,000 tons of VOC per year so that the cost effectiveness is computed as $228 per ton VOC reduction (1990$).. Document No. 05.09.009/9010.463 III-13 94 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Comments: The EPA did not account for potential cost differences for reformulating coatings to various content limits. Instead, EPA assumed that a reformulation has a certain cost to manufacturers regardless of the target content limit, or the anticipated VOC reduction (Ducey, 1997). Status: Demonstrated Last Reviewed: 1997 Additional Information: In its analysis of the proposed federal rule, EPA assumed that the cost of product reformulation would bring the VOC content limit for each noncompliant coating down to the level of the standards. The EPA, however, noted the likelihood that some manufacturers will likely reduce the VOC content of their coatings to levels significantly below the limits in the rule (EPA, 1996). The at-the-limit assumption, therefore, likely results in emission reductions being understated. In its cost analysis, insufficient data were available for EPA to distinguish reformulation costs between different coating types (i.e., the reformulation cost for flat paints is equal to the reformulation cost for all other affected paint types). The EPA noted the likelihood of reformulation costs varying from product to product (EPA, 1995). References: Ducey, 1997: E.

These VOC limits in the SCAQMD for multi-color, traffic, and lacquer coatings took effect on January 1, 1998, while the Phase I limits for flat coating took effect on January 1, 2001. Reductions in VOC emissions from these coatings are achieved through the use of product reformulation and product substitution.

The SCAQMD estimated that manufacturers would use an acetone formulation with an associated cost of $2 per gallon to meet the proposed 550 grams per liter (g/L) VOC limit for lacquers. For flats, South Coast estimated a zero cost for complying with the near-term 100 g/L limit since most flats sold in California are already in compliance with this limit. For traffic and multi-color coatings, the SCAQMD estimated that a cost savings was likely to be associated with reformulation due to a decrease in the cost of input materials. (The estimated magnitude of the savings is not documented in the SCAQMD report.) Costs were estimated by multiplying the cost per gallon data to total gallons sold. The resulting weighted average cost effectiveness value was converted to 1990 dollars using the 1995:1990 producer price index for Standard Industrial Classification (SIC) code 2851 (Paints and Allied Products). Because capital cost information was not available, capital costs were not estimated for this analysis.

Affected SCC: 2401080000 Marine: SIC 373, Total: All Solvent Types Pollutant(s) PM10 PM2.5 EC OC NOx VOC S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 24% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: The costs for model plants with emissions less than 100 tpy are used to estimate the overall cost effectiveness (Pechan, 1998). EPA assumed that no additional equipment is required for any facility and capital costs are therefore zero (EPA, 1994). Implementation of this regulation is expected to result in nationwide annualized costs for existing shipyards of about $2 million (1992$), for a cost effectiveness of $2,090 per ton of VOC reduced (1990$) (60FR64330, 1995). EPA stated that since most of the sources are in NAAs, the costs for the NESHAP also reflect costs associated with CTG compliance. Cost Effectiveness: $2,090 per ton VOC reduced (1990$) is the cost effectiveness used in AirControlNET (60FR64330, 1995).

A metal can is defined as a "usually cylindrical metal container", but governmental agencies and industry groups use differing criteria to identify cans including shape, materials, capacity, phase of product contained, and material thickness (gauge). Decorative tins, bottle caps and jar lids are also included in the can coating category since many of these items are coated on the same line where can coating takes place. Cans consist of can bodies and can ends. Metal can surface coating facilities include two-piece beverage can body facilities, two- piece food can body facilities, one-piece aerosol can body facilities, sheetcoating facilities, three-piece food can body assembly facilities, three-piece non-food can body assembly facilities, and end lining facilities. EPA evaluated VOC emission control options for the two-piece beverage can, two- piece food can and sheetcoating facilities using a PTE in conjunction with a thermal oxidizer in the MACT standard-setting process for this source category.

Equipment Life: 30 years (PTE); 10 years (thermal oxidizer) Rule Effectiveness: 100% for point and area sources Penetration: 100% Cost Basis: The cost analysis is based on an average of PTE and oxidizer capital and operating and maintenance costs developed in an EPA background document for three model metal can coating plants evaluated by EPA for the Metal Can Surface Coating MACT standard (40 CFR Part 63 Subpart KKKK). Consistent with the OAQPS Control Cost Manual, an interest rate of 7% was used to determine the capital recovery factor. Although PTE costs were annualized over a 10 year period, PTE life is expected to be 30 years, also consistent with the OAQPS Control Cost Manual. Each PTE was assumed to capture 100% of all VOC emissions. All captured emissions were assumed to be vented to thermal oxidizer. The EPA background document does not specify year dollars, so the cost basis is assumed to be in terms of 2002 dollars, consistent with the year of issuance of the background document. Cost Effectiveness: The cost effectiveness is $8,469 per ton HAP reduction (2002$). The cost effectiveness is based on total annualized capital and operation/maintenance (O&M) costs of $49,862,900 and total HAP reductions of 5,888 tons per year for all three facilities combined.

The rule also mentions several options for reducing VOC emissions, including using reformulated low-VOC content compliant coatings, powder coating for both general and high gloss coatings, UV curable coatings, high transfer efficiency coating applications, and increased effectiveness of add-on control equipment. The original rule was promulgated in 1979 and has been amended several times, most recently in November 2001. This rule applies to emissions that result from the coating of metal parts and products including furniture (SCC 2401025000), appliances (SCC 2401060000), and miscellaneous manufacturing (SCC 2401090000).

Cost effectiveness is the average cost per ton of the expected allocation of control measures to sources in the South Coast Air Quality Basin. Factors affecting cost include product reformulations and level of add-on controls required. SCAQMD notes that add-on control equipment is considerably more expensive than low-VOC coating reformulation (SCAQMD, 1996). Cost Effectiveness: The cost effectiveness used in AirControlNET is $2,027 per ton VOC reduced (1990$). Comments: SCAQMD notes that powder coating is very effective in reducing VOC emissions because in most cases it contains less than 3 percent VOC. Moreover, it is applied by electrostatic attraction which has high transfer efficiency (SCAQMD, 1996). Status: Demonstrated Last Reviewed: 1996 Document No. 05.09.009/9010.463 III-1414 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Additional Information: Since its original adoption in 1979, SCAQMD Rule 1107 has been amended several times to adjust the compliance schedule, and modify provisions due to delayed progress in the development and use of compliant coatings (SCAQMD, 2001). This control measure represents requirements as they stood in 1996. Coating of metal parts and products are applied to prevent corrosion and to enhance appearance. The metal parts or products undergo a cleaning process to remove grease, dust, mill scale, or corrosion. Often they are also pretreated to improve coating adhesion. Commonly, the metal substrate is washed through an alkaline, chromate, or non-caustic solution wash and is then rinsed in water. After the final rinse, the metal normally passes through an oven to evaporate water before the coating is applied (SCAQMD, 1996). Coating is applied either by spraying, dipping, or flow coating. Conventional, high volume low pressure (HVLP), or electrostatic spray guns are used for spraying (SCAQMD, 1996). After coating, the parts are either baked in ovens or air-dried depending on the type of coating. References: SCAQMD, 1996: South Coast Air Quality Management District.

Affected SCC: 2401070000 Motor Vehicles: SIC 371, Total: All Solvent Types Pollutant(s) PM10 PM2.5 EC OC NOx VOC S02 NH3 CO Hg V* V = pollutant reduction; X = pollutant increase, * = major pollutant Control Efficiency: 37% from uncontrolled Equipment Life: Not Applicable Rule Effectiveness: 100% Penetration: 100% Cost Basis: EPA calculated the total costs of the regulation as the sum of the costs for necessary process modifications and employee training costs. The total capital investment for process modifications is $10 million, the majority of which is for the purchase of pumping and mixing equipment to process higher-solids coatings. The costs for training personnel to use the new coatings was estimated separately for coating manufacturers, distributors, and body shops. The total cost of the proposed rule includes coating manufacturer process modification costs, and costs for training coating manufacturer representatives, distributors, and body shop personnel. A training cost of $425 per employee was applied to manufacturing employees, distributors, and painters at body shops. Process modification and training costs were annualized over 10 years at an interest rate of 7 percent for a total annual cost of $4.5 million (EPA, 1995). Cost Effectiveness: The cost effectiveness is $118 per ton VOC reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 1998 Document No. 05.09.009/9010.463 III-1417 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Additional Information: In April 1996, EPA proposed a national standard to reduce VOC emissions from the use of automobile refinish coatings (61FR19005, 1996). EPA's regulation does not affect the application of automobile refinish coatings, and therefore body shops nationwide are not directly affected by the regulation's requirements. The rule is expected to reduce VOC emissions by 37 percent from baseline levels. Research and development costs associated with formulating low-VOC coatings were not considered, since these costs are assumed to have been incurred as the result of state regulations (EPA, 1995).

VOC emissions from degreasing operations can be reduced by the use of low-VOC content solvents, and by changes in operating practices (EPA, 1993). The original MACT was promulgated in 1994. Degreasing operations are associated with VOC emissions as a result of using solvents to clean contaminants from parts, products, tools, machinery, and equipment.

The cost effectiveness used to estimate costs reflect a weighted average across all model facility sizes. Costs reflects distribution of emissions by model plant size. The range of cost effectiveness is from a SAVINGS of $148 for in-line cleaners to a cost of $128 for small cleaners (Pechan, 1998). Cost Effectiveness: The cost effectiveness used in AirControlNET is a SAVINGS of $69 per ton VOC reduction (1990$). (Pechan, 1998). Comments: Status: Demonstrated Last Reviewed: 1998 Document No. 05.09.009/9010.463 III-1444 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Additional Information: There are two basic types of solvent cleaning equipment: batch cleaners, and in-line or continuous cleaners. Batch vapor cleaners heat the solvent to boiling and create a solvent vapor zone within the machine in which parts are cleaned. In-line cleaners are enclosed devices distinguished by a conveyor system to continuously supply a stream of parts for cleaning. Batch cold cleaning machines use non-boiling solvent to clean parts. The halogenated solvent cleaning NESHAP reflects the application of the maximum achievable control technology (MACT) for all batch vapor and in-line units. For area source batch cold cleaning machines, the standard reflects the GACT (59FR61801, 1994). References: Pechan, 1998: E.H.

(SCAQMD, 1996; SCAQMD, 1997) The amendments are estimated to reduce emissions from solvent degreasing tanks (as opposed to hand- held cleaning) by 76 percent by using widely available no- or low-VOC solvents. The expected cost is $1,391 per ton of VOC reduced (1997 dollars) (SCAQMD, 1997). Cost Effectiveness: The cost effectiveness is estimated to be $1,248 per ton VOC reduced (1990$) (SCAQMD, 1997). Comments: Status: Demonstrated Last Reviewed: 1997 Document No. 05.09.009/9010.463 III-1446 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Additional Information: Rule 1122 applies to both batch and conveyorized degreasing. The latest amendments, from 1997, set lower VOC limits for batch loaded and conveyorized cold cleaners at 50 grams of VOC per liter of material (SCAQMD, 1997). Open-top vapor degreasers include a tank for holding the solvent and a heating system to heat and vaporize the liquid solvent. As the liquid solvent vaporizes, a vapor layer is formed above the liquid solvent. The cleaning action is provided by the solvent vapor condensing on the cooler (dirty) parts and either dissolving or flushing contaminants from the parts. The cleaning operation is complete when the temperature of the parts reaches that of the vapor, thereby ending the condensation process (SCAQMD, 1996). The soiled solvent is periodically removed and replaced with fresh solvent.

Consistent with the OAQPS Control Cost Manual, an interest rate of 7% was used to determine the capital recovery factor. Although the PTE is expected to have a life of 30 years, PTE costs were annualized over a 10 year period (the expected life of the thermal oxidizer). Each PTE was assumed to capture 100% of all VOC emissions. All captured emissions were assumed to be vented to a regenerative thermal oxidizer having a 95% control efficiency. Therefore, the net VOC control efficiency is 95%. Year 1998 dollars were specified for cost calculations in the EPA background document for the paper and other web coating industry. Cost Effectiveness: The cost effectiveness is $1,503 per ton VOC reduction (1998$). The cost effectiveness is based on an annualized capital cost of $659,351 and an annual operation and maintenance (O&M) cost of $671,167 averaged over two model paper and other web printing plants.

Since its adoption, this rule has been amended numerous times incorporating more stringent VOC limits as the technology and low VOC coatings have become available. The last amendment in March 1996 was to exempt aerosol coatings and to provide rule consistency with the recently adopted ARB Aerosol Coating Products Rule. There are a variety of control methods to reduce VOCs from plastic, rubber, and glass coatings operations. VOC emissions can be reduced by using reformulated low-VOC content compliant coatings, UV curable coatings, high transfer efficiency coating applications and increased effectiveness of add-on control equipment.

Comments: Status: Demonstrated Last Reviewed: 1996 Additional Information: The majority of VOC emissions from this source category are generated from coating, cleaning, and other manufacturing operations used in the production of plastic, rubber and glass substrates. Glass products manufactured in the South Coast Basin are primarily mirrors (SCAQMD, 1996). During the coating application process for mirrors, glass is passed under a flow coater or roll coater. The coating or product is either forced-dried or air-dried. Molded or formed glass objects can be either dipped or sprayed. Document No. 05.09.009/9010.463 III-1460 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES Rubber products are typically spray painted. Artistic designs are applied to the substrate through a mask or by using transfer decals. Adding pigment to the rubber during its manufacturing can avoid the need for painting. Plastic products use the widest variety of coating application techniques. The majority of coatings are sprayed, but dip coating, flow coating, and roller coating are also used. Coatings are typically air- dried or forced-dried, because excess heat can cause them to melt and deform. Masks are used to manufacture toys and multicolored products. Coatings may be eliminated by using colored plastic or transfer decals. Letters, numbers, and designs may be transferred to an object by a process similar to a letter press.

The rule sets maximum allowable VOC content limits for 55 different categories of AIM coatings, and affects the manufacturers and importers of the coating products. VOC content limits defined in the national rule took effect on September 11, 1999. Manufacturers of FIFRA - regulated coatings had until March 10, 2000 to comply. Sixty-four percent of the products included in the 1990 industry survey meet the VOC content limits in this rule and, therefore, there will be no costs to reformulate these products. The manufacturer of a product that does not meet the VOC content limits will be required to reformulate the product if it will continue to be marketed, unless the manufacturer chooses to use an alternative compliance option such as the exceedance fee or tonnage exemption provision.

Industry representatives estimated the level of effort required by a representative firm to research and develop a new prototype coating to be 2.5 scientist-years over a 3-year time period. EPA calculated an annualized cost of $17,772 per reformulation (1991 dollars) based on an assumed cost of $100,000 per scientist-year as amortized over an assumed repopulation cycle of 2.5 years. The estimated average cost to reformulate a product was $87,000. The total estimated national cost of the AIM Coating Federal rule is 25.6 million per year (1991 dollars). Cost Effectiveness: EPA estimated emission reductions of 106,000 tons of VOC per year so that the cost effectiveness is computed as $228 per ton VOC reduction (1990$).. Comments: The EPA did not account for potential cost differences for reformulating coatings to Document No. 05.09.009/9010.463 III-1466 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES various content limits. Instead, EPA assumed that a reformulation has a certain cost to manufacturers regardless of the target content limit, or the anticipated VOC reduction (Ducey, 1997). Status: Demonstrated Last Reviewed: 1997 Additional Information: In its analysis of the proposed federal rule, EPA assumed that the cost of product reformulation would bring the VOC content limit for each noncompliant coating down to the level of the standards. The EPA, however, noted the likelihood that some manufacturers will likely reduce the VOC content of their coatings to levels significantly below the limits in the rule (EPA, 1996). The at-the-limit assumption, therefore, likely results in emission reductions being understated. In its cost analysis, insufficient data were available for EPA to distinguish reformulation costs between different coating types (i.e., the reformulation cost for flat paints is equal to the reformulation cost for all other affected paint types). The EPA noted the likelihood of reformulation costs varying from product to product (EPA, 1995). References: Ducey, 1997: E.

The SCAQMD estimated that manufacturers would use an acetone formulation with an associated cost of $2 per gallon to meet the proposed 550 grams per liter (g/L) VOC limit for lacquers. For flats, South Coast estimated a zero cost for complying with the near-term 100 g/L limit since most flats sold in California are already in compliance with this limit. For traffic and multi-color coatings, the SCAQMD estimated that a cost savings was likely to be associated with reformulation due to a decrease in the cost of input materials. (The estimated magnitude of the savings is not documented in the SCAQMD report.) Costs were estimated by multiplying the cost per gallon data to total gallons sold. The resulting weighted average cost effectiveness value was converted to 1990 dollars using the 1995:1990 producer price index for Standard Industrial Classification (SIC) code 2851 (Paints and Allied Products). Because capital cost information was not available, capital costs were not estimated for this analysis. Cost Effectiveness: CARB indicated that costs ranged from a savings of $8,600 per ton (for pool Document No. 05.09.009/9010.463 III-1468 Report ------- AT-A-GLANCE TABLE FOR AREA SOURCES finishes) to cost of $12,800 per ton of VOC reduced (for specialty enamels) (CARB, 1989). The cost effectiveness range is attributable to the wide diversity of coatings. AirControlNET uses a cost effectiveness of $1,443 per ton VOC reduction based on a weighted average of national sales data by coating type (EPA, 1996) (1990$).

The rule requires manufacturers of the coatings sold in the SCAQMD to meet the VOC limit requirements provided in the rule between 2002 and 2006. Reductions in VOC emissions from these coatings are achieved through the use of product reformulation and product substitution.

SCAQMD assumed a 10 percent price increase per gallon for compliant coatings meeting Phase II and estimated the cost based on the number of gallons produced. Costs vary significantly among individual coatings categories. Because capital cost information was not available, capital costs were not estimated for this analysis. Cost Effectiveness: AirControlNET uses a cost effectiveness of $4,017 per ton VOC reduction (1990$). Comments: Status: Demonstrated Last Reviewed: 1996 Additional Information: The South Coast notes that the process of collecting reformulation cost data for these categories is very complex due to the resin technology used in lower-VOC, high-performance industrial maintenance coatings (silicon-based resins, or polyurethanes) and the number of resin systems involved (Berry, 1997).

The rule requires manufacturers to limit VOC content of the specified coatings sold in the SCAQMD using a phased-in approach specifying compliance dates that depend on the coating type. Compliance dates range from 1/1/03 to 7/1/08. Reductions in VOC emissions from these coatings are achieved through the use of product reformulation and product substitution. In AirControlNET this measure only applies to traffic markings.

As an estimate, Pechan uses the highest incremental cost effectiveness estimate for any individual product for the Phase II amendments of $26,000 per ton (1998 dollars). This value is about double the average of Phase II products. This cost estimate is highly uncertain as no specific cost data are available (Pechan, 1999). Because capital cost information was not available, capital costs were not estimated for this analysis. Cost Effectiveness: AirControlNET uses an overall cost effectiveness of $10,059 per ton VOC reduction (1990$). Comments: Status: Demonstrated Last Reviewed: 1996 Additional Information: The Phase III controls apply to additional consumer products that are not affected by the near-term measures. These measures, which are expected to take effect between 2000 and 2005, are expected to result in an additional 25 percent VOC reduction from consumer products.

The highest costs for add-on controls are associated with specialized and small plants (Pechan, 1999). The industry sponsored study whose information was included in the guideline document used a 10 percent discount rate in the computation of a capital recovery factor (EPA, 1996). Cost Effectiveness: Depending on the control, a cost effectiveness range of $468 per ton to more than $22,100 per ton VOC reduced is estimated. Emissions reductions range from 67 to 98 percent (Pechan, 1999). The cost effectiveness used in AirControlNET is $20,000 per ton VOC reduced (1990$). Comments: Status: Demonstrated Last Reviewed: 1999 Additional Information: Where facilities can achieve comparable reductions through the use of hybrid waterborne systems, full waterborne systems or other alternative coatings, reductions may be higher and costs may be lower than those estimated based on this add-on control measure.
