Project XL Progress Report Crompton Corporation Sistersville Facility In 1995, the U.S. Environmental Protection Agency (EPA) embarked on a series of innova- tive initiatives in an effort to test new ways to achieve greater public health and environmental protection at a more reasonable cost. Through Proj ect XL, which stands for excellence and Leadership, EPA enters into specific proj ect agreements with public or private sector spon- sors to test regulatory, policy, and procedural alternatives that will produce data and experi- ences to help the Agency make improvements in the current system of environmental protec- tion. The goal of Project XL is to implement 50 projects that will test ways of producing superior environmental performance with improved economic efficiencies, while increasing public participation through active stakeholder processes. As of January 2001, EPA has reached its goal of 5 0 proj ects in the implementation phase. EPA Proj ect XL Progress Reports provide overviews of the status of XL projects that are implementing Final Project Agreements (FPAs). The progress reports are available on the Internet via EPAs Proj ect XL web site at http://www.epa.gov/Project XL. Hard copies may be obtained by contacting the Office of Policy, Economics and Innovation's (formerly Office of Reinvention) Proj ect XL general information number at 202-260-5754. Additional information on Proj ect XL is available on the web site or by contacting the general information number. The information and data presented in the January 2001 Progress Report is current as of December 2000. Background Crompton Corporation (formerly Witco Corporation) is a specialty chemical manufacturer. This XL proj ect focuses on Crompton's chemical manufacturing plant located six miles south of Sistersville, West Virginia. Five other towns are located in the vicinity of the plant, including Ben's Run, Friendly, Middlebourne, Paden City, and St. Mary's. The population of these com- munities totals approximately 1,500 people. The Crompton facility is located along the east side of the Ohio River in a rural setting near the border of Tyler and Pleasants Counties. Both Tyler County (the county where the Crompton Corporation XL Project Sistersville, West Virginia Major Milestones • 7 September 29, 1995 Crompton XL Proposal Submitted / October 17, 1997 Final Project Agreement Signed 7 December 11, 1998 Waste Minimization/ Pollution Prevention Study Report Completed / July 30, 1999 First Annual Report Submitted 7 • 2002 Project Reevaluation ------- Crompton Corporation XL Project 1-31-01 plant is located) and Pleasants County (the down-river county) are predominantly rural, with populations totaling 10,000 and 7,500 respectively. Since the arrival of Union Carbide in the 1950's, these communities have relied on the manufacturing industry, including Crompton, for employment. Six hundred residents of Tyler and Pleasants County are employed by Crompton at the Sistersville plant. Crompton produces a broad range of silicone and silane products including surfactants, emulsions, antifoams, and oils. The operating units are situated centrally within the facility and encompass approximately 50 acres. The Crompton XL project strives to reduce air emissions through a combination of flexible air pollution control and waste minimization/pollution prevention (WM/PP) activities. The poly ether methyl capper unit is the focus of emission control efforts. The capper unit is the site of a two-step reaction that results in one of Crompton's products, methyl-capped polyether. This project also involves the facility's generation of solid waste and two lined one-million-gallon surface impoundments that contain process wastewater. In return for a deferral of certain air emissions standards, Crompton has achieved superior environmental performance at this facility by: • installing a process vent incinerator that is destroying 98 percent by weight of organic compound emissions in the facility's process vent stream, resulting in a reduction of over 200,000 pounds of emissions per year; • recovering and reusing over 400,000 pounds of methanol per year, resulting in the reduction of over 500,000 pounds of sludge per year; • reducing methanol air emissions from the wastewater treatment unit by more than 20,000 pounds per year; and • conducting a WM/PP study to identify opportunities for additional reductions in waste generated by the facility Crompton estimates annual cost savings from emission reductions and methanol recycling at approximately $ 16,000. When combined with other Pollution Prevention ("P2") opportunities identified by the Pollution Prevention Council, annual, recurring cost savings are $240,000 for those implemented in 1997, $25,000 for those implemented in 1998, $650,000 for those implemented in 1999, and $381,000 for those implemented during the first half of 2000. These total $1,010,000. (These savings, however, do not include the expenses of implementing the P2 measures. The actual, net savings will be less.) The Experiment The Crompton proj ect tests whether regulatory flexibility will lead to reductions in air emissions and hazardous waste greater than what would be achieved by otherwise required emissions controls for the two hazardous waste surface impoundments located onsite. The proj ect strives to reduce pollution through a combination of flexible air pollution control, waste minimization, and pollution prevention activities. The Flexibility As an incentive to achieve superior environmental performance at Crompton's facility, EPA and the West Virginia Division of Environmental Protection (WVDEP) have offered Crompton regulatory flexibility in the areas of pollution control technology and air emissions. The statutory programs, and the EPA offices administering those programs, that affect the Crompton XL project are: • Clean Air Act (CAA) programs administered by EPA's Office of Air Quality Planning and Standards; 2 ------- Crompton Corporation XL Project 1-31-01 • Resource Conservation and Recovery Act (RCRA) programs administered by EPA's Office of Solid Waste; and • Pollution Prevention Act (PPA) programs administered by EPA's Office of Prevention, Pesticides, and Toxic Substances. EPA's Region 3 office is also active in the development and implementation of the Crompton XL project as a member of the WM/PP Study Advisory Committee, which participated in the design of the WM/PP study and reviewed and commented on progress reports from the study. RCRA Subpart CC contains requirements for the control of air emissions from hazardous waste tanks, surface impoundments, and containers. EPA and WVDEP agreed to a deferral of the RCRA Subpart CC organic air emission standards through a site-specific rule and consent order, respectively, applicable to Crompton's two surface impoundments. These surface impoundments are one-million-gallon reservoirs that hold process waste- water from the facility's pollution control equipment and other sources. If not deferred, the Subpart CC stan- dards would have required Crompton to install air emission controls on these surface impoundments. Alterna- tively, Crompton could have replaced the existing reservoirs with open-top tanks that are not regulated under RCRA Subpart CC regulation, and air emissions would not have been reduced. However, with the deferral, Crompton has implemented both the emissions control measures on the capper unit and the WM/PP activities mentioned above. In the first quarter of 2001, EPA plans to propose National Emission Standards for Hazardous Air Pollutants (NESHAPs) under Section 112 of the CAA that would be applicable to miscellaneous organic processes; this standard is called "the MON." The MON is anticipated to apply to a broad spectrum of chemical processes not regulated under other NESHAP rules. The MON is expected to include controls for process vents, and wastewater collection and treatment systems. It is anticipated that the MON will apply to the capper unit at the Crompton facility, and that controls on both the production unit and wastewater treatment system will be required. EPA believes that the MON will include process vent control requirements similar to those already implemented under the proj ect. Accordingly, EPA expects to receive superior environmental benefits from the proj ect only until such time as compliance with the technical requirements of the MON is required (the "MON compliance date"). At the expected end of the proj ect (assumed to be late in 2004, the year in which it is expected that the MON may require control of capper unit emissions, hence approximately six years after the installation of the emissions controls), any required emission controls will be placed on the capper unit and the waste water treatment unit and voluntary methanol collection could continue. The FPA provides for re-evalua- tion of the proj ect following proposal of the new standards. Crompton will prepare a proj ect re-evaluation report within 90 days following the close of the comment period for the proposed new standards. If EPA, WVDEP, and other stakeholders agree to continue the project, the FPA will be amended to include new approaches to providing superior environmental performance. EPA and WVDEP consider the WM/PP initiatives important to the superior environmental performance offered by the Crompton XL proj ect. Some of the WM/PP initiatives could be undermined, however, if the require- ments proposed in CAA Subpart YYY are approved. CAA Subpart YYY (New Source Performance Stan- dards) contains proposed regulations to control VOC emissions from wastewater generated by certain process units. As proposed, these standards would generally apply to new or modified process units that generate a wastewater stream with VOC concentrations above a specified amount and that produce any of a specific list of substances. As proposed, CAA Subpart YYY would apply to certain WM/PP initiatives if Crompton begins recovering substances, such as acetic acid, listed in proposed CAA Subpart YYY. If Crompton starts recover- ing these substances, EPA and WVDEP will consider issuing a limited-scope "allowable exclusion/allowable increase" deferral of the regulations on a case-by-case basis, provided that EPA and WVDEP determine that this deferral will not cause an increase in actual emissions of volatile organic compounds (VOCs) or cause a net ------- Crompton Corporation XL Project 1-31-01 adverse environmental impact, and that Crompton will remain in compliance with the FPA's provisions. If such a deferral is granted, EPA and WVDEP will propose regulations implementing the deferral. Promoting Innovation and System Change Proj ect XL provides EPA opportunities to test and implement approaches that protect the environment and advance collaboration with stakeholders. EPA is continually identifying specific ways in which XL proj ects are helping to promote innovation and system change. The innovations and system changes emerging from the Crompton XL proj ect are described below. National Emission Standards for Hazardous Air Pollutants (NESHAP) for Miscellaneous Organic Pro- cesses. Flexibility in the control of air pollutants by Crompton's Sistersville plant shows the adaptability that is possible in complying with air regulatory requirements. These adaptations may be applicable to other plants that are facing similar emission requirements and should be investigated relative to existing and future air emissions issues. As noted previously, it is likely that the MON will apply in the future to require some level of control of emissions from the capper unit and the wastewater collection and treatment system. That event would not diminish the superior environmental performance obtained prior to the compliance date of the MON under this proj ect. The total emission reductions and pollution prevention achieved as a result of implementation of the proj ect during the minimum proj ect term will be significant. As EPA works to promulgate NESHAPs applicable to miscellaneous organic processes; the Agency will gather data on, and assess the performance of, the technol- ogy used at the Sistersville plant. The partners in this proj ect realize that a dynamic, rather than static, FPA encourages the parties to identify additional opportunities for superior environmental benefits during the course of thi s proj ect. Proj ect reevaluation provides the parties with a fluid process, during the course of the proj ect, to identify proj ect enhancements to achieve superior environmental results at the facility. Accordingly, the parties may determine during reevaluation that implementation of those enhancements supports continuation of the expanded proj ect past the compliance date of the MON. Waste Minimization and Pollution Prevention (WM/PPj. Crompton committed to conducting a Waste Minimization/Pollution Prevention (WM/PP) study to identify opportunities for additional reductions in waste generated by the facility. Normally, WM/PP assessments are conducted as single events and outside of the routine business operations of companies. However, the Crompton study was an employee-driven effort that sought to integrate the pollution prevention process into the company's standard business practices, facilitate employee involvement, and implement a site-specific process tailored to the particular needs at the facility. A Pollution Prevention Council, consisting of employees from throughout the plant was established at the beginning of 1999 to help foster and communicate "P2" ideas and monitor progress. Crompton used a multiphased process to conduct the WM/PP study: (1) identifying and characterizing plantwide wastes and emissions; (2) screening and prioritizing these wastes and emissions; (3) identifying pollution prevention options; (4) screening and prioritizing pollution prevention options; (5) examining the technical and economic feasibility of these op- tions; and (6) developing an implementation plan. As of July 2000,370 WM/PP options have been identified, of which 26 are at some stage of study and 67 have been implemented. The 67 WM/PP initiatives that have been implemented at the Sistersville plant, have resulted in atotal annual, recurring cost savings of $1,010,000 and the prevention of 2,900,000 pounds of wastes. (These savings, however, do not include the expenses of implementing the P2 measures. The actual, net savings will be less.) Crompton, also identified potential future cost savings of over $1,000,000 per year. As a result of theRCRA deferral, alone, Crompton expects future savings of about $700,000 over the life of the project. Crompton's project approach toward pollution preven- tion and recycling may offer an innovative model for other chemical intermediate-product manufacturers. Innovative Technology. The Crompton XL project provides a pilot for testing the benefits of allowing regula- tory flexibility in the technology used to control air emissions under RCRA regulations, in order to provide ------- Crompton Corporation XL Project 1-31-01 superior and less expensive environmental protection. In return for a deferral of air emission standards for its surface impoundments, Crompton agreed to install a thermal oxidizer and route the process vents from its poly ether methyl capper unit to that oxidizer for control of organic air emissions. Since the process vent incin- erator was installed on Crompton's capper unit in April 1998, air emissions have been reduced by more than twice the amount that would have otherwise been achieved without Proj ect XL. On July 15,1998, a perfor- mance test demonstrated that the thermal oxidizer is reducing total organics in the vent stream by 99.99 percent, versus the 98 percent minimum required by the EPA.

Environmental Performance This section summarizes progress in meeting the environmental performance described in the FPA for Crompton. Air Emissions from Capper Unit 1999 Actual - 0.341 1998 Actual 1995 Baseline Estimated without XL 59.9 1 3 50 i i i i 277 277 i 100 150 200 250 300 Thousands of Pounds per Year Reduce Air Emissions from Capper Unit: Methyl chloride, dimethyl ether, and methanol emissions gener- ated in the capper unit during production of the methyl- capped polyether are being collected and routed to a new process vent incinerator installed on the capper unit. Crompton estimated the incinerator would destroy at least 98 percent of the organic compounds (by weight) in the vent stream, or about 271,000 pounds of these by- products per year. Progress: In 1998, the capper unit emitted a total of 59,898 pounds of organic compounds. This data in- cludes emissions from the capper prior to the incinerator startup on April 1,1998. In 1999, the capper unit emitted a total of 341 pounds of organic compounds. Crompton estimates that 199,445 pounds would have been emitted in 1999 if the XL proj ect had not been implemented; a reduction of 199,104 pounds. Performance tests indicate that the oxidizer is reducing total organics in the vent stream by 99.99 percent, versus the 98 percent minimum required by the agreement. Reduce Organic Capper Unit Discharges to Wastewater Treatment System: Production of methyl- capped polyether generates excess methanol in the capper unit. Formerly, a portion of this methanol was condensed, collected, and either disposed of in the facility's wastewater treatment unit or incinerated. Under this XL project, Crompton agrees to direct a minimum of 95 percent of the collected methanol towards reuse and recycling, or subj ect it to thermal recovery or treatment, thus minimizing biotreatment of the methanol in waste- water treatment units. Crompton estimated that approximately 550,000 pounds of methanol that otherwise would be biotreated in the wastewater system would be transferred to tank trucks or rail cars for reuse or recycling each year. ------- Crompton Corporation XL Project 1-31-01 1/1/99-6/30/00 Actual 4/1/98-12/31/98 Actual Performance Goal 1995 Baseline 100% 100% 95% - 0% 20 40 60 80 Percent of Collected Methanol Reuse 100 Progress: In 1998, the capper unit discharged Collected Methanol Reuse 271,000 pounds of methanol to the wastewater treatment system, resulting in a reduction of nearly 519,000 pounds per year of methanol as compared to 1995 baseline figures. All the 424,254 pounds, or 100 percent of recovered methanol by weight, were reused, recycled, or thermally recovered or treated in 1998, exceeding the 95 percent performance standard established in the agreement. In 1999, the capper unit generated a total of 572,000 pounds of methanol and the methanol recovery operation collected 428,000 pounds of methanol. As discussed in the FPA, a portion of the methanol generated in the capper unit cannot be economically collected, but rather goes to the onsite waste water treatment unit via a steam ej ector, or to the thermal oxidizer. This accounts for the 144,000 pounds of methanol that were generated by the capper unit but not recovered. One Performance Standard of the FPA requires that "on an annual basis, the Sistersville Plant shall ensure that a minimum of 95 percent by weight of the methanol collected by the methanol recovery operation is utilized for reuse, recovery, or thermal recovery/ treatment." In 1999,100 percent of the 428,000 pounds collected was reused. This exceeds the performance standard by five percent. Reduce Wastewater Treatment Sludge Generated from Capper Unit Methanol: As a result of Crompton's methanol recovery and reuse efforts, the amount of sludge generated by the wastewater treatment system from capper operations, and disposed of in an onsite hazardous waste landfill was expected to decrease by an estimated 815,000 pounds peryear, from an estimated 1,425,000 pounds peryearto an estimated 610,000 pounds per year. Wastewater Treatment Sludge Generated from Capper Unit Methanol 1999 Actual 1998 Actual 1995 Baseline Estimated without XL 254.8 420 1177 Progress: In 1998, 420,053 pounds of sludge were generated by the wastewater treatment system from capper operations representing a 757,247 pound reduction per year as compared with 1995 baseline figures. In 1999,254,851 pounds of sludge were generated by the wastewater treatment system from capper operations. Crompton estimates that 931,782 pounds would have been generated in 1999 if the XL project had not been implemented; a reduction of 676,930 pounds. Reduce Air Emissions from Wastewater Treatment Unit: Reducing the amount of methanol that is sent to the wastewater treatment system leads to a reduction in air emissions from the wastewater treatment system that could occur during the treatment of that methanol. Crompton estimated that as a result of its recovery and reuse of methanol, air emissions from the wastewater treatment system would be reduced by 38,000 pounds peryear, from 140,300 pounds peryearto 102,000 pounds per year. 1425 200 400 600 800 1000 1200 1400 1600 Thousands of Pounds per Year ------- Crompton Corporation XL Project 1-31-01 Air Emissions from Wastewater Treatment System 1999 Actual 1998 Actual Performance Goal 1995 Baseline Estimated without XL 105.6 102* 140 140 20 40 60 80 100 120 140 160 Thousands of Pounds per Year *This goal is not specified in the FPA; it is a voluntary performance goal estimated by Crompton. Progress: In 1998, 88,932 pounds of air emissions were released by the wastewater treatment unit; a reduction of 51,368 pounds from the 1995 baseline total of 140,300 pounds. In 1999,105,646 pounds of air emissions were released by the wastewater treat- ment unit. Crompton estimates that 111,892 pounds would have been released in 1999 if the XL proj ect had not been implemented; a reduction of 6,246 pounds. Implement a Comprehensive Waste Minimization/ Pollution Prevention Project: The WM/PP Project included a study of plant operations that identified existing and future WM/PP opportunities and devel- oped a plan to implement those that are technically and economically feasible. Through the use of an advisory committee, Crompton has involved EPA, WVDEP, The International Chemical Workers Union Council, and other stakeholders in the study and implementation phases of the WM/PP Project. Progress: Crompton delivered the final WM/PP Study Report on December 11,1998. Highlights of the study are described below. A WM/PP Study Team (made up of Crompton Corporation management and employees and an independent contractor, STV Incorporated) was established to guide and conduct the daily activities of the WM/PP Study. An advisory committee (made up of representatives of the community, regulatory agencies, and the plant) was established to offer comments and suggestions throughout the process. Four employee brainstorming sessions were a key component of the process. These sessions included repre- sentatives from a cross-section of the plant's technical and operating staffs. The goals of the brainstorming sessions were to develop criteria and methods to screen, prioritize, and analyze the feasibility of WM/PP opportunities; to increase awareness of pollution prevention; to evaluate and prioritize opportunities based on technical and economic feasibility; to prepare implementation plans; and to determine how to measure progress. In addition, a week-long survey conducted by the Waste Reduction And Technology Transfer Foundation (WRATT) helped the facility identify waste and emission sources, and suggested ways to reduce the quantity or toxicity of plant wastes. A number of the study's pollution prevention options were determined to be technically and economically feasible; these options are currently being implemented. The WM/PP Study Report is available on the EPA website and also from Crompton. The Annual Report issued on July 31,2000 states that 370 WM/PP oppor- tunities have been identified, of which 26 are at some stage of study and 67 have been implemented. ------- Crompton Corporation XL Project 1-31-01 Crompton Corporation Sistersville Facility [formerly Witco) Capper Operations* Year Opportunity was Implemented Air Emissions and Sludge Reduction plus Methanol Recycle (Excludes capital savings from XL project) Actual for Calendar Year 1 999 Number of New P2 Opportunities Implemented Recurring Wastes Prevented, Latest Estimates, Ibs/yr 1,310,921 Recurring Cost ^ .

Stakeholder Participation Stakeholder involvement during the proj ect development stage was encouraged in several ways. The methods included communicating through the media (newspaper and radio announcements), directly contacting inter- ested parties, and offering an educational program on the regulatory programs impacted by the XL project. Stakeholders have been kept informed via mailing lists, newspaper articles, public meetings and the establish- ment of public files at the Sistersville JAiblic Library and the EPA Region 3 office. 10 ------- Crompton Corporation XL Project 1-31-01 A local environmental group, the Ohio Valley Environmental Coalition, was contacted but stated that it did not have time to participate actively in the development of the XL proj ect. However, a representative from the Natural Resources Defense Council, a national environmental interest group, participated in conference call meetings with the XL proj ect team and provided comments during the FPA's development. There are few homes located near the facility, and therefore, few local stakeholders other than the employees of the facility expressed interest in actively participating in the development of the proj ect. The Sistersville Plant provided stakeholders with regular proj ect development updates by circulating meeting and conference call minutes. As this XL proj ect's continues implementation, the stakeholder involvement program will shift its focus to ensuring that stakeholders are apprised of the proj ect's status, and have access to information sufficient to judge the success of this Proj ect XL initiative. Facilitating stakeholder involvement during the term of the proj ect likely will include holding general public meetings to present periodic status reports and making available data and other information as it is generated. Crompton has appointed a Sistersville Plant Proj ect XL contact at the facility to serve as a resource for the community. In addition, the plant is required to make copies of semiannual and annual proj ect reports available to all interested parties. As of April 2000, participating stakeholders reported that they were satisfied with the stakeholder involvement process, but felt that the process was too long (two years between submittal of the first proposal and the signing of the FPA). The community representatives felt that the EPA was too stringent in their requirements, and that improvements in EPAs efficiency would save time and money for everyone involved. The community represen- tatives stated that the rapport between the community and Crompton has always been good, but that EPA had more difficulty working within the industrial culture of the community. Representatives of the community, Crompton, EPA, and WVDEP were all disappointed by the low level of community involvement. The commu- nity representatives were not sure if this was a sign of apathy or an indication that the community trusts Crompton and is satisfied with the information that has been made available to them. The EPA and WVDEP were impressed with Crompton's initiative and respect in the community. Company representatives felt that the proj ect was a good way for both EPA and Crompton to learn how to work together. Six-Month Outlook Key focus areas for successful implementation of the FPA over the next six months include the third semiannual proj ect report due January 31,2001, the third annual proj ect report due July 31,2001, and the ongoing imple- mentation of options identified in the WM/PP EPA is expected to propose new MON standards in the first quarter of the year 2001. As per the FPA, Crompton will prepare a proj ect re-evaluation report within 90 days following the close of the comment period for the new standards. If EPA, WVDEP, and other stakeholders agree to continue the proj ect, the FPA will be amended to include new approaches to providing superior environmental performance.

The information sources are current through July 2000. Glossary Air Emissions: Pollution discharged into the atmosphere from smokestacks, other vents, and surface areas of commercial or industrial facilities; from residential chimneys; and from motor vehicle, locomotive, or aircraft exhausts. Air Emission Standard: The maximum amount of air-polluting discharge legally allowed from a single source, either mobile or stationary. Allowable Exclusion/Allowable Increase: Where Crompton implements a Qualifying Change to a process unit at the Facility, EPA and WVDEP expect to defer applicability of CAA Subpart YYY for the Qualifying Change. Baseline: The measure by which future environmental performance can be compared. Biotreatment: A process that uses bacteria to consume organic waste. Capper Unit: The poly ether methyl capper unit is the point in Crompton's production process where a two-step reaction occurs that results in the intended end product, methyl-capped poly ether. Clean Air Act (CAA): The Clean Air Act is the Federal law that regulates air emissions from area, stationary, and mobile sources. This law authorizes the U. S. Environmental Protection Agency to establish National Ambi- ent Air Quality Standards (NAAQS) to protect public health and the environment. CAA Subpart YYY (New Source Performance Standards): Proposed regulations to control VOC emissions from wastewater generated by certain process units. As proposed, these standards would generally apply to new or modified process units that generate a wastewater stream with VOC concentrations above a specified amount and that produce any of a specific list of substances ("Subpart YYY Substances"), such as acetic acid as a product or by-product. Consent Order: An agreement between two parties that does not involve any judicial action. Deferral: A legally sanctioned delay in compliance with regulations. Dimethyl Ether: A colorless flammable gas. Used in refrigeration, as a solvent, and in chemical production. Harmful if inhaled; irritating to eyes. Discharges: Flow of liquid or chemical emissions from a facility into water or air. Final Project Agreement (FPA): The FPA outlines the details of the XL project and each party's commitments. The project's sponsors, EPA, state agencies, tribal governments, other regulators, and direct participant stake- holders negotiate the FPA. 12 ------- Crompton Corporation XL Project 1-31-01 Hazardous Waste: By-products of society that can pose a substantial or potential hazard to human health or the environment when improperly managed. These wastes possess at least one of four characteristics—ignitability, corrosivity, reactivity, or toxicity—or appear on special EPA lists. Impoundment: A body of water or sludge confined by a dam, dike, floodgate, or other barrier. Incineration: A treatment technology involving destruction of waste by controlled burning at high temperatures. Incinerator: A furnace for burning waste under controlled conditions. Media: Specific environments-air, water, soil-which are the subject of regulatory concern and activities. Methanol: An alcohol that can be used as an alternative fuel or as a gasoline additive. Poisonous if ingested. Methyl Chloride: A colorless flammable gas. Used in the production of chemicals, as a solvent and refrigerant, and as a food additive. Mildly toxic if inhaled. Multi-media: Several environmental media, such as air, water, and land. "The MON': The National Emission Standard for Hazardous Air Pollutants (NESHAP) for the source category "Miscellaneous Organic Chemical Production and Processes." Some examples of these processes are: explo- sives production, photographic chemicals production, polyester resins production, and the production of paints, coatings and adhesives. National Ambient Air Quality Standards (NAAQS): Standards established by EPA applicable to outdoor air throughout the country. National Emissions Standards for Hazardous Air Pollutants (NESHAPs): Emissions standards set by EPA for air pollutants not covered by National Ambient Air Quality Standards (NAAQS), that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness. Primary standards are designed to protect human health, and secondary standards are designed to protect public welfare (e.g., building facades, visibility, crops, and domestic animals). Organic Compounds: Naturally occurring (animal or plant-produced) or synthetic substances containing mainly carbon, hydrogen, nitrogen, and oxygen. Pollution Prevention (P2): Identifying, altering, or eliminating areas, processes, and activities that create exces- sive waste products or pollutants. Such activities, consistent with the Pollution Prevention Act (PPA) of 1990, are conducted across all EPA programs. Process Vent: A gas stream discharged to the atmosphere (with or without passing through a control device or recovery device) from chemical processing equipment. Resource Conservation and Recovery Act (RCRA): RCRA gives EPA the authority to control hazardous waste from the "cradle to grave." This includes the generation, transportation, treatment, storage, and disposal of hazardous waste. RCRA also sets forth a framework for the management of nonhazardous wastes. RCRA enables EPA to address environmental problems that could result from underground tanks storing petroleum and other hazardous substances. RCRA focuses only on active and future facilities and does not address abandoned sites. RCRA Subpart CC: Requirements for the control of air emissions from hazardous waste tanks, surface im- poundments, and containers. The name comes from the fact that they are found in the regulations in Subpart CC of 40 CFR Parts 264 and 265. Sludge: A semisolid residue from air or water treatment processes; it can be a hazardous waste. 13 ------- Crompton Corporation XL Project 1-31-01 Thermal Oxidizer: An enclosed device that destroys organic compounds by thermal oxidation, i.e. reacting at elevated temperatures with oxygen. Thermal Recovery or Treatment: In the Crompton XL project, refers to the use of collected methanol in fuels blending or as a feed to any combustion device. Waste Minimization: Measures or techniques that reduce the amount of wastes generated during industrial production processes; term is also applied to recycling and other efforts to reduce the amount of waste going into the waste stream. Wastewater: The spent or used water from a home, community, farm, or industry that contains dissolved or suspended matter. 14 ------- |
