1.0 INTRODUCTION
The document "Compilation of Air Pollutant Emission Factors" (AP-42) has
been published by the U.S. Environmental Protection Agency (EPA) since 1972.
Supplements to AP-42 have been routinely published to add new emission source
categories and to update existing emission factors. AP-42 is routinely updated by
EPA to respond to new emission factor needs of EPA, state, and local air pollution
control programs and industry.
An emission factor relates the quantity (weight) of pollutants emitted to a
unit of activity of the source. The uses for the emission factors reported in AP-42
include:
1. Estimates of area-wide emissions;
2. Emission estimates for a specific facility; and
3. Evaluation of emissions relative to ambient air quality.
The purpose of this report is to provide background information from test
reports to support calculation of emission factors for sewage sludge incinerators
(SSI). Including the introduction (Chapter 1.0), this report contains five chapters.
Chapter 2.0 gives a description of the sewage sludge incineration industry. It
includes a characterization of the industry, an overview of the different process
types, a description of emissions, and a description of the technology used to control
emissions resulting from sewage sludge incineration. Chapter 3.0 is a review of
emissions data collection and analysis procedures. It describes the method used to
locate and collect test data, the screening of emission data reports, and the quality
rating system for both emissions data and emission factors. Chapter 4.0 details
pollutant emission factor development. It includes the review of specific data sets,
the results of data analysis, and the data base protocol. Chapter 5.0 presents the
AP-42 Section 2.5.

2.0 INDUSTRY DESCRIPTION
Incineration is a means of disposing of sewage sludge generated by the
treatment of wastewater from residential, commercial, and industrial
establishments. When compared to other forms of disposal, incineration has the
advantages of reducing the solid mass, destroying or reducing the organic matter
present in the sludge, and the potential for recovering energy through combustion.
Disadvantages include the necessity of ash disposal and the potential for air
emissions of pollutants.
This section provides background information on the current status of
sewage sludge incineration. In Section 2.1, the sewage sludge incineration industry
is briefly overviewed. Incinerator and emission control design are described in
detail in Sections 2.2 and 2.3, respectively.
2.1 CHARACTERIZATION OF THE INDUSTRY
There are currently about 170 sewage sludge incineration (SSI) plants in
operation in the United States. Three main types of incinerators are used:
Multiple hearth, fluidized bed, and electric infrared. 1 Some sludge is co-fired with
municipal solid waste in combustors based on refuse combustion technology.
Unprocessed refuse co-fired with sludge in combustors based on sludge incinerating
technology is limited to multiple hearth incinerators. Over 80 percent of the
identified operating sludge incinerators are of the multiple hearth design. About
15 percent are fluidized bed combustors and about 3 percent are electric. The
remaining combustors co-fire refuse with sludge.
Most SSI facilities are located in the eastern United States, though there are
a significant number on the West Coast. New York has the largest number of
facilities with 33. Pennsylvania and Michigan have 21 and 19 sites, respectively.
Approximately 5.9 million dry megagrams (Mg) (6.5 million dry tons) of
sludge are generated in U.S. municipal wastewater plants each year.2 It is
estimated that 25 percent of this sludge is incinerated.^ This means that about
1.5 million dry Mg (1.6 million dry tons) of sludge is incinerated annually. A

database containing results of the National Sewage Sludge Use and Disposal
Survey conducted in 1988, and sponsored by the U.S. EPA, is available to the public
from the National Technical Information Service (NTIS). The database contains
general operating, financial, and use disposal practice data, as well as chemical
concentrationss from sludge samples collected prior to disposal.
2.2 SLUDGE INCINERATION TECHNOLOGIES
Sewage sludge incineration refers to the oxidation of combustible materials
generated by wastewater sewage treatment plants to reduce the volume of solid
waste. The first step in the process of sewage sludge incineration is the dewatering
of the sludge. Sludge is generally dewatered until it is about 15 to 30 percent
solids. Above 25 percent solids, the sludge will usually burn without auxiliary fuel.
After dewatering, the sludge is sent to the incinerator where thermal oxidation
occurs. The unburned residual ash is removed from the incinerator, usually on a
continuous basis, and is disposed. A portion of the noncombustible waste, as well
as unburned volatile organic compounds, is carried out of the combustor through
entrainment in the exhaust gas stream. Air pollution control devices, primarily wet
scrubbers, are used to remove the entrained pollutants from the exhaust gas
stream. The cleaned gas stream is then exhausted to the ambient air, and the
collected pollutants, now suspended in the scrubber water, are sent back to the
head of the wastewater treatment plant.
Several different incineration technologies are used for sewage sludge
incineration. They include 1) multiple hearth, 2) fluidized bed, 3) electric,
4) co-incineration with refuse, 5) single hearth cyclone, 6) rotary kiln, and 7) high
pressure, wet air oxidation. In this section, only the first four will be discussed in
detail; multiple hearth and fluidized bed are most commonly used. The other
technologies are not widely used in the United States.4
2.2.1 Multiple Hearth Furnaces
The multiple hearth furnace (MHF) was originally developed for mineral ore
roasting nearly a century ago. The air-cooled variation has been used to incinerate
sewage sludge since the 1930s. The basic multiple hearth furnace is a verticlly
-------
oriented cylinder. The outer shell is constructed of steel, lined with refractory, and
surrounds a series of horizontal refractory hearths. A hollow cast iron rotating
shaft runs through the center of the hearths. Attached to the central shaft are the
rabble arms, which extend above the hearths. Cooling air for the center shaft and
rabble arms is introduced into the shaft by a fan located at its base. Each rabble
arm is equipped with a number of teeth, approximately 6 inches in length, and
spaced about 10 inches apart. The teeth are shaped to rake the sludge in a spiral
motion, alternating in direction from the outside in, then inside out, between
hearths. Typically, the upper and lower hearths are fitted with 4 rabble arms, and
the middle hearths are fitted with two. Burners, providing auxiliary heat, are
located in the sidewalls of the hearths.
In most multiple hearth furnaces, partially dewatered sludge is fed onto the
perimeter of the top hearth by conveyors or pumps. The rabble arms move the
sludge through the incinerator by raking the sludge toward the center shaft where
it drops through holes located at the center of the hearth. On the next hearth, the
sludge is raked in the opposite direction. This process is repeated in the
subsequent hearths. The effect of the rabble motion is to break up solid material to
allow better surface contact with heat and oxygen. A sludge depth of about one
inch is maintained in each hearth at the design sludge flow rate.
Scum may also be fed to one or more hearths of the incinerator. Scum is the
material that floats on wastewater. It is generally composed of vegetable and
mineral oils, grease, hair, waxes, fats, and other materials that will float, and it
usually has a higher heating value and a larger volatile fraction than sludge. Scum
may be removed from many treatment units including pre-aeration tanks,
skimming tanks, and sedimentation tanks. Quantities of scum are generally small
compared to those of other wastewater solids.
Ambient air is first ducted through the central shaft and its associated rabble
arms. A portion, or all, of this air is then taken from the top of the shaft and
recirculated into the lowermost hearth as preheated combustion air. Shaft cooling
air which is not circulated back into the furnace is ducted into the stack
-------
downstream of the air pollution control devices. The combustion air flows upward
through the drop holes in the hearths, countercurrent to the flow of the sludge,
before being exhausted from the top hearth. Air enters the bottom to cool the ash.
Provisions are usually made to inject ambient air directly into the middle hearths
as well.
From the standpoint of the overall incineration process, multiple hearth
furnaces can be divided into three zones. The upper hearths comprise the drying
zone where most of the moisture in the sludge is evaporated. The temperature in
the drying zone is typically between 425 and 760°C (800 and 1,400°F). Sludge
combustion occurs in the middle hearths (second zone) as the temperature is
increased between 815 and 925°C (1,500 and 1,700°F). The combustion zone can be
further subdivided into the upper-middle hearths where the volatile gases and
solids are burned, and the lower-middle hearths where most of the fixed carbon is
combusted. The third zone, made up of the lowermost hearth(s), is the cooling zone.
In this zone, the ash is cooled as its heat is transferred to the incoming combustion
air.
Multiple hearth furnaces are sometimes operated with afterburners to
further reduce odors and concentrations of unburned hydrocarbons. In the
afterburn process, furnace exhaust gases are ducted to a chamber where they are
mixed with supplemental fuel and air and are completely combusted. Some
incinerators have the flexibility to allow sludge to be fed to a lower hearth, thus
allowing the upper hearth(s) to function essentially as an afterburner.
Under normal operating conditions, 50 to 100 percent excess air must be
added to a MHF in order to ensure complete combustion of the sludge. Besides
enhancing contact between fuel and oxygen in the furnace, these relatively high
rates of excess air are necessary in order to compensate for normal variations in
both the organic characteristics of the sludge feed and the rate at which it enters
the incinerator. When an inadequate amount of excess air is available, only partial
oxidation of the carbon will occur with a resultant increase in emissions of carbon
monoxide, soot, and hydrocarbons. Too much excess air, on the other hand, can
2-4
-------
cause increased entrainment of participate and unnecessarily high auxiliary fuel
consumption.
Multiple hearth furnace emissions are usually controlled by a venturi
scrubber, an impingement tray scrubber, or a combination of both. Wet cyclones
are also used. Wet electrostatic precipitators (ESPs) are being installed as retrofits
where tighter limits on particulates and metals are required by State regulations.
2.2.2 Fluidized Bed Incinerators
Fluidized bed technology was first developed by the petroleum industry to be
used for catalyst regeneration. Fluidized bed technology was first used for
municipal sludge incineration in 1962. Fluidized bed combustors (FBCs) consist of
a verically oriented outer shell constructed of steel and lined with refractory.
Tuyeres (nozzles designed to deliver blasts of air) are located at the base of the
furnace within a refractory-lined grid. A bed of sand and ash, approximately 0.75
meters (2.5 feet) thick, rests upon the grid. Two general configurations are
distinguished based on how the fluidizing air is injected into the furnace. In the
"hot windbox" design, the combustion air is first preheated by passing through a
heat exchanger where heat is recovered from the hot flue gases. Alternatively,
ambient air can be injected directly into the furnace from a cold windbox.
Partially dewatered sludge is fed into the bed of the furnace. Air injected
through the tuyeres, at pressures from 20 to 35 kPa (3 to 5 psig), fluidizes the bed of
hot sand and the incoming sludge. Temperatures of 750 to 925°C (1,380 to
1,700°F) are maintained in the bed. Residence times are typically 2 to 5 seconds.
As the sludge burns, fine ash particles are carried out the top of the furnace. Some
sand is also removed in the air stream; sand make-up requirements are on the
order of 1 percent for every 60 hours of operation.4
The overall process of combustion of the sludge occurs in two zones. Within
the bed itself (zone 1), evaporation of the water and pyrolysis of the organic
materials occur nearly simultaneously as the temperature of the sludge rapidly
increases. In the second zone (freeboard area), the remaining free carbon and
2-5
-------
combustible gases are burned. The second zone functions essentially as an
afterburner.
Fluidization of the bed achieves nearly ideal mixing between the sludge and
the combustion air, and the turbulence facilitates the transfer of heat from the hot
sand to the sludge. The most noticeable impact of the improved mixing and
combustion provided by a fluidized bed incinerator is the lower excess air required
for complete combustion of the sludge. Typically, FBCs can achieve complete
combustion with 20 to 50 percent excess air, about half the excess air required by
multiple hearth furnaces. As a consequence, FBC incinerators have generally lower
fuel requirements compared to MHF incinerators.
Fluidized bed incinerators most often have venturi scrubbers or
venturi/impingement tray scrubber combinations for emissions control.
2.2.3 Electric Incinerators
The first electric furnace was installed in 1975, and their use is not common.
An electric incinerator consists of a horizontally oriented, insulated furnace. A
woven wire belt conveyor extends the length of the furnace, and infrared heating
elements are located in the roof above the conveyor belt. Combustion air is
preheated by the flue gases and is injected into the discharge end of the furnace.
Electric incinerators consist of a number of prefabricated modules that are linked
together to provide the necessary furnace length.
The dewatered sludge is conveyed into one end of the incinerator. An
internal roller mechanism levels the sludge into a continuous layer approximately
one inch thick across the width of the belt. The sludge is sequentially dried and
then burned as it moves beneath the infrared heating elements. Ash is discharged
into a hopper at the opposite end of the furnace. The preheated combustion air
enters the furnace above the ash hopper and is further heated by the outgoing ash.
The direction of air flow is countercurrent to the movement of the sludge conveyor.
Exhaust gases leave the furnace at the feed end. Excess air rates vary from 20 to
70 percent.
2-6
-------
Compared to MHF and FBC technologies, the electric furnace offers the
advantage of lower capital cost, especially for smaller systems. However, electric
costs in some areas may make an electric furnace infeasible. Another concern is
replacement of various components such as the woven wire belt and infrared
heaters, which have 3- to 5-year lifetimes.
Electric incinerator emissions are usually controlled with a venturi scrubber
or some other wet scrubber.
2.2.4 Co-incineration and Co-firing
Wastewater treatment plant sludge generally has a high water content and,
in some cases, fairly high levels of inert materials. As a result, its net fuel value is
often low. If one or more combustible waste materials are combined with sludge in
a co-incineration scheme (i.e., municipal solid waste and sewage sludge), a furnace
feed can be created that has both a low water concentration and a heat value high
enough to sustain combustion with little or no supplemental fuel.
Virtually any waste material that can be burned can be combined with
sludge in a co-incineration process. Common materials for co-incineration are
municipal solid waste, wood waste, and agricultural waste. Thus, a municipal or
industrial waste can be disposed of while providing an autogenous (self-sustaining)
sludge feed, thereby solving two disposal problems.
There are two basic approaches to burning sludge with municipal solid waste
(MSW): 1) use of MSW combustion technology by adding dewatered or dried sludge
to the MSW combustion unit, and 2) use of sludge combustion technology by adding
raw or processed MSW as a supplemental fuel to the sludge furnace. With the
latter, MSW is processed by removing noncombustibles, shredding, air-classifying,
and screening. Waste that is more finely processed is less likely to cause problems
such as severe erosion of the hearths, poor temperature control, and refractory
failures. 5
Sewage sludge can also be co-fired with a non-waste material such as coal in
order to produce sustained combustion.

2.3 SEWAGE SLUDGE INCINERATION EMISSIONS AND
CONTROL TECHNOLOGIES
2.3.1 Pollutant Emissions
Sewage sludge incinerators can emit significant quantities of pollutants. The
major pollutants emitted are: 1) particulate matter, 2) metals, 3) carbon monoxide
(CO), 4) nitrogen oxides (NOX), 5) sulfur dioxide (SO2), and 6) unburned
hydrocarbons. Partial combustion of sludge can result in emissions of intermediate
products of incomplete combustion (PICs) including toxic organic compounds.
Uncontrolled particulate emission rates vary widely depending on the type of
incinerator, the volatile compound and moisture contents of the sludge, and the
operating practices employed. Generally, uncontrolled particulate emissions are
highest from fluidized bed incinerators because suspension burning results in much
of the ash being carried out of the incinerator with the flue gas. Uncontrolled
emissions from multiple hearth and fluidized bed incinerators are extremely
variable, however. Electric incinerators appear to have the lowest rates of
uncontrolled particulate release of the three major furnace types, possibly because
the sludge is not disturbed during firing. In general, higher airflow rates increase
the opportunity for particulate matter to be entrained in the exhaust gases. Sludge
with low volatile content or high moisture content may compound this situation by
requiring more supplemental fuel to burn. As more fuel is consumed, the amount of
air flowing through the incinerator is also increased. However, no direct correlation
has been established between air flow and particulate emissions.
Metals emissions are affected by metals content of the sludge, fuel bed
temperature, and the level of particulate matter control. Since metals volatilized in
the combustion zone condense in the exhaust gas stream, most metals (except
mercury) are associated with fine particulate and are removed by the particulate
matter control device.
Carbon monoxide is formed when available oxygen is insufficient for
complete combustion or when combustion temperatures are too low. When
incomplete combustion occurs, CO is formed in place of CO2-
-------
Nitrogen and sulfur oxide emissions are primarily the result of oxidation of
nitrogen and sulfur in the sludge. Therefore, these emissions can vary greatly
based on local and seasonal sewage characteristics.
Emissions of volatile organic compounds also vary greatly with incinerator
type and operation. Incinerators with countercurrent air flow such as multiple
hearth designs provide the greatest opportunity for unburned hydrocarbons to be
emitted. In the MHF, hot air and wet sludge feed are contacted at the top of the
furnace. Any compounds easily volatalized from the solids are immediately vented
from the furnace at temperatures too low to completely destruct them.
2.3.2 Control Technologies
Particulate emissions from sewage sludge incinerators have historically been
controlled by wet scrubbers, since the associated sewage treatment plant provides
both a convenient source and a good disposal option for the scrubber water. The
types of existing sewage sludge incinerator controls range from low pressure drop
spray towers and wet cyclones to higher pressure drop venturi scrubbers and
venturi/impingement tray scrubber combinations. Electrostatic precipitators and
baghouses are also employed, primarily where sludge is co-fired with municipal
solid waste.
There are three basic types of wet scrubbers:
1. Low energy (spray tower), primarily for acid gas control;
2. Medium energy (impingement scrubbers such as packed column, baffle
plate, and liquid impingement) for PM and/or acid gas control; and
3. High energy (venturi), primarily for PM control.
Low energy scrubbers (spray towers) are usually circular in cross-section.
The liquid is sprayed down the tower as the gases rise. Acid gases are
absorbed/neutralized by the scrubbing liquid. Large particles are removed by
impingement on the liquor pool, and finer particles are removed as the flue gas
rises through the tower. Low energy scrubbers mainly remove particles larger than
5-10 microns.^
2-9
-------
Medium energy devices mostly rely on impingement to facilitate removal of
PM. This can be accomplished through a variety of configurations, such as packed
columns, baffle plates, and liquid impingement scrubbers.
High energy venturi scrubbers are designed for applications requiring high
removal efficiencies of submicron particles. They are often used for PM removal. A
typical venturi scrubber consists of a converging section, a throat, and a diverging
section.
The most widely used control device applied to a multiple hearth incinerator
is the impingement tray scrubber. Older units use the tray scrubber alone while
combination venturi/impingement tray scrubbers are widely applied to newer
multiple hearth incinerators and to fluidized bed incinerators. Most electric
incinerators and some fluidized bed incinerators use venturi scrubbers only.
In a typical combination venturi/impingement tray scrubber, hot gas exits
the incinerator and enters the precooling or quench section of the scrubber. In some
cases, hot flue gas from the incinerator passes through a waste heat boiler for steam
generation before going to the gas scrubber. Spray nozzles in the quench section
cool the incoming gas, and the quenched gas then enters the venturi section of the
control device.
Venturi water is usually pumped into an inlet weir above the quencher. The
venturi water enters the scrubber above the throat and floods the throat surface.
This eliminates build-up of solids and reduces abrasion. Turbulence created by
high gas velocity in the converging throat section deflects some of the water
traveling down the throat into the gas stream. Particulate matter carried along
with the gas stream impacts on these water particles and on the water wall. As the
scrubber water and flue gas leave the venturi section, they pass into a flooded elbow
where the stream velocity decreases, allowing the water and gas to separate. Most
venturi sections come equipped with variable throats. By restricting the throat
area within the venturi, the linear gas velocity and pressure drop increase. Up to a
certain point, increasing the venturi pressure drop increases the removal efficiency.
2-10
-------
Venturi scrubbers typically attain 60 to 99 percent removal efficiency for
participate matter, depending on pressure drop and particle size distribution.6
At the base of the flooded elbow, the gas stream passes through a connecting
duct to the base of the impingement tray tower. Gas velocity is further reduced
upon entry to the tower as the gas stream passes upward through the perforated
impingement trays. Water usually enters the trays from inlet ports on opposite
sides and flows across the tray. As gas passes through each perforation in the tray,
it creates a jet which bubbles up the water and further entrains solid particles. A
mist eliminator at the top of the tower reduces the carryover of water droplets in
the stack effluent gas. The impingement section can contain from one to four trays,
but most systems for which data are available have two or three trays.
Control devices such as fabric filters and dry ESPs are generally not used to
control emissions from sewage sludge incinerators due to the high moisture content
of the emission stream.

3.0 GENERAL DATA REVIEW AND ANALYSIS PROCEDURES
3.1 LITERATURE SEARCH AND SCREENING
The first step of this investigation involved a search primarily to identify
recently-published literature relating to criteria and noncriteria pollutant emissions
associated with sewage sludge incineration. This task included an extensive
literature search, contacts to identify ongoing projects within EPA, and electronic
database searches. Source test reports and background documents for the previous
AP-42 section on sewage sludge incinerators were also retrieved from the EPA.
The literature search conducted for the update of this section included on-
line library system searches of the Office of Research and Development/National
Technical Information Service (ORD/NTIS) Database and the NSPS/CTG/CTC
database. The Crosswalk/Air Toxics Emission Factors (XATEF), VOC/PM Chemical
Speciation (SPECIATE), and the Aerometric Information Retrieval System
(AIRS)/Facility Subsystem Emission Factors (AFSEF) electronic databases were
also searched.
Contact was also made with the EPA's Office of Water (Alan Rubin), Risk
Reduction Engineering Laboratory (Harry Bostian), and Emission Standards
Division (Gene Grumpier), and the author of the AP-40 sewage sludge incineration
chapter (Cal Brunner).
3.2 LITERATURE AND DATA REVIEW
To reduce the large amount of literature collected to a final group of
references pertinent to this report, the following general criteria were used:
• Only primary references of emissions data were used.
• Test study source processes were clearly identified.
• Test studies specified whether emissions were controlled or
uncontrolled.
• Studies referenced for controlled emissions specify the control device.
• Data support (i.e., calculation sheets, sampling and analysis
description) was supplied.
3-1
-------
• Test study units were convertible to selected reporting units.
• Test studies that were positively biased to a particular situation were
excluded.
A final set of reference materials was compiled after a thorough review of the
pertinent reports, documents, and information according to these criteria.
3.2 EMISSION DATA QUALITY RATING SYSTEM
As delineated by the Emission Inventory Branch (EIB), the reduced data set
was ranked for quality. The ranking of the data was used to identify questionable
data. Each data set was ranked as follows:
A - When tests were performed by sound methodology and reported in
enough detail for adequate validation. These tests are not necessarily
EPA reference test methods, although such reference methods are
preferred.
B - When tests were performed by a generally sound methodology, but
lack enough detail for adequate validation.
C - When tests were based on an untested or new methodology or are
lacking a significant amount of background data.
D - When tests were based on a generally unacceptable method but the
method may provide an order-of-magnitude value for the source. 1
The selected rankings were based on the following criteria:
• Source operation. The manner in which the source was operated is
well documented in the report. The source was operating within
typical parameters during the test.
• Sampling procedures. The sampling procedures conformed to a
generally acceptable methodology. If actual procedures deviated from
accepted methods, the deviations are well documented. When this
occurs an evaluation is made of the extent such alternative procedures
could influence the test results.
• Sampling and process data. Many variations can occur unnoticed and
without warning during testing. Such variations can induce wide
deviations in sampling results. If a large spread between test results
cannot be explained by information contained in the test report, the
data are suspect and are given a lower rating.
3-2
-------
Analysis and calculations. The test reports contain original raw data
sheets. The nomenclature and equations used were compared to those
(if any) specified by EPA to establish equivalency. The depth of review
of the calculations was dictated by the reviewer's confidence in the
ability and conscientiousness of the tester, which in turn was based on
factors such as consistency of results and completeness of other areas
of the test report.
3.3 PARTICLE SIZE DETERMINATION
There is no one method which is universally accepted for the determination
of particle size. A number of different techniques can be used which measure the
size of particles according to their basic physical properties. Since there is no
"standard" method for particle size analysis, a certain degree of subjective
evaluation was used to determine if a test series was performed using a sound
methodology for particle sizing.
For pollution studies, the most common types of particle sizing instruments
are cyclones and cascade impactors. Traditionally, cyclones have been used as a
precipitator ahead of a cascade impactor to remove the larger particles. These
cyclones are of the standard reverse-flow design whereby the flue gas enters the
cyclone through a tangential inlet and forms a vortex flow pattern. Particles move
outward toward the cyclone wall with a velocity that is determined by the
geometry, size and flow rate of the cyclone. Large particles are propelled by
centrifugal force towards the wall and are collected. A series of cyclones with
progressively decreasing cut-points can be used to obtain particle size distributions.
Cascade impactors used for the determination of particle size in process
streams consist of a series of plates or stages containing either small holes or slits
with the size of the openings decreasing from one plate to the next. In each stage of
an impactor, the gas stream passes through the orifice or slit to form a jet that is
directed toward an impaction plate. For each stage, there is a characteristic
particle diameter that has a 50 percent probability of impaction. This characteristic
diameter is called the cut-point (D50) of the stage. Typically, commercial
3-3
-------
instruments have six to eight imp action stages with a backup filter to collect those
particles which are either too small to be collected by the last stage or which are
retrained off the various impaction surfaces by the moving gas stream.
3.4 PAETICULATE SIZE DATA ANALYSIS METHODOLOGY
The particulate emission information contained in the various reference
documents was reduced to a common format using a family of computer programs
developed especially for this purpose. These programs use the so-called "spline"
fits. Spline fits result in cumulative mass size distributions very similar to those
which would be drawn using a French curve and fully logarithmic graph paper. In
effect, the logarithm of cumulative mass is plotted as a function of the logarithm of
the particle size, and a smooth curve with a continuous, non-negative derivative is
drawn.
The process by which this smooth cumulative distribution is constructed
involves passing an interpolation parabola through three measured data points at a
time. The parabola is then used to interpolate additional points between measured
values. When the set of interpolated points are added to the original set of data, a
more satisfactory fit is obtained than would be the case using only the measured
data. The size-specific emission factors are determined once the size distribution is
obtained by a spline fit.
3.5 EMISSION FACTOR QUALITY RATING SYSTEM
The quality of the emission factors developed from analysis of the test data
was rated utilizing the following general criteria:
A - Excellent. Developed only from A-rated test data taken from many
randomly chosen facilities in the industry population. The source
category is specific enough to minimize the variability within the
source population.
B - Above average. Developed only from A-rated test data from a
reasonable number of facilities. Although no specific bias is evident, it
is not clear if the facilities tested represent a random sample of the
industries. As with the A rating, the source category is specific enough
to minimize the variability within the source population.
3-4
-------
C - Average. Developed only from A- and B-rated test data from a
reasonable number of facilities. Although no specific bias is evident, it
is not clear if the facilities tested represent a random sample of the
industry. As with the A rating, the source category is specific enough
to minimize the variability within the source population.
D - Below average. The emission factor was developed only from A- and
B-rated test data from a small number of facilities, and there is reason
to suspect that these facilities do not represent a random sample of the
industry. There also may be evidence of variability within the source
category population. Any limitations on the use of the emission factor
are noted in the emission factor table.
E - Poor. The emission factor was developed from C- and D-rated test
data, and there is reason to suspect that the facilities tested do not
represent a random sample of the industry. There also may be
evidence of variability within the source category population.
Limitations on the use of these factors are always clearly noted. 1
The use of these criteria is somewhat subjective and depends to an extent on
the individual reviewer. Details of the rating of each candidate emission factor are
provided in Chapter 4 of this report.

4.0 POLLUTANT EMISSION FACTOR DEVELOPMENT
This chapter describes the test data and methodology used to develop
pollutant emission factors for the sewage sludge incineration industry.
4.1 REVIEW OF SPECIFIC DATA SETS
A total of 108 references were documented and reviewed during the
literature search. These references are listed at the end of this chapter.
The following efforts were made to ensure that the selection and rating of
reference documents did not introduce a bias in the data. The majority of
references used were compliance test reports. Given the impetus for compliance
testing, these reports would be expected to characterize facilities with various levels
of maintenance, operation, and control. The remaining references were classified as
research or special study tests. In some cases, it could be reasoned that such
studies would involve testing of facilities with above average maintenance,
operation, and control and would, therefore, not be representative of the industry.
Rather than downgrade the ratings for these references, each reference was
considered on its own merit. The original group of 108 documents was reduced to a
final set of primary references utilizing the criteria outlined in Chapter 3.0. For
the reference documents not used, the reason(s) for rejection are summarized below:

The following is a discussion of the data contained in each of the primary references
used to develop candidate emission factors.
4.1.1 References 1 Through 3
References 1 through 3 are tests performed on three different sludge
incinerators by an EPA contractor. These tests were performed to gather emission
data for a study conducted under Tier 4 of the National Dioxin Study. The primary
objective of the tests was to determine the presence of dioxins and/or furan
emissions from the incineration process. Controlled data for these emissions are
provided in References 1 and 2. Reference 3 contains controlled and uncontrolled
emissions data. In References 1 and 3, testing results were also presented for
4-2
-------
uncontrolled emissions of oxides of nitrogen (NOX), sulfur dioxide (862), and carbon
monoxide (CO). Uncontrolled nonmethane volatile organic compound (VOC)
emissions results were provided in References 1 and 2. These values were obtained
from continuous monitoring of the combustion gases during the dioxin/furan tests.
A rating of A was assigned to the data in each of the tests for criteria
pollutants.
4.1.2 Reference 4
This report comprises emission tests performed on a fluidized-bed incinerator
to demonstrate the relationship between the temperature of incineration and the
emissions of certain trace metals. The tests were performed at three different
operating temperatures. Results were obtained for controlled emissions of total
particulate matter and metals (arsenic [As], cadmium [Cd], chromium [Cr], lead
[Pb], and nickel [Ni]). Modified Method 5 and source assessment sampling system
(SASS) train results were presented for each test, but the report states that SASS
train results were used in preference to the Modified Method 5 results because
approximately 10 times as much flow was sampled by the SASS train method.
Metal emissions did increase with increasing incineration temperature. Operating
temperatures for a fluidized-bed incinerator usually range from 680 to 820°C
(1250 to 1500°F). These tests were conducted at 704, 816, and 927°C (1300, 1500,
and 1700°F). The data in this report were assigned a rating of B. Particle size
determinations for controlled emissions were made by sampling with an Andersen
Cascade Impactor.
4.1.3 References 5o through 5r
These references contain data from particulate and gaseous emissions tests
conducted at four sludge incinerators. Each test provides controlled particulate
matter emission data, and, except for incinerator "q," uncontrolled data are also
presented. Controlled emission factors for Cd, Cr, Pb, SO2, and H2SO4 are
presented for each incinerator. Data from incinerator "p" include controlled results
for Ni. Uncontrolled emission factors for SO2 and H2SO4 are presented for
incinerators "o," "p," and "r."
4-3
-------
A rating of A was assigned to the data for incinerators "o" and "p." These
reports provided adequate detail for validation, and the methodology appeared to be
sound. The report for incinerator "q" did not contain sufficient process information
to determine whether the incinerator was operating within design specifications.
The report for incinerator "r" showed a wide, unexplained deviation in test results.
For these reasons, References 5q and 5r were given a B rating.
4.1.4 References 6 and 7
These are chromium and organics screening study test reports. The tests
were conducted by an EPA contractor on two incinerators located at the same site.
Tests were conducted at the inlet and outlet of the scrubber to determine the
concentration and mass emission rates of total particulate matter, semivolatile
organic compounds and VOCs. Results were also obtained for controlled methane
VOC emissions.
Total particulate matter emissions were determined using EPA Method 5.
Volatile organic compounds were measured with a Volatile Organic Sampling Train
(VOST) and semivolatile organic compound emissions were determined using
Modified Method 5 with an XAD-2 resin trap. The data for metals, semivolatile
organic compounds, and total particulate matter presented in Reference 7 were
assigned a rating of A. The report states that the VOC results must be considered
as "estimates" because the samples saturated the analytical systems during
analysis. Further, the inlet results were obtained from one incinerator and the
outlet results from another. Therefore, the volatile organic emission results were
assigned a rating of D and will be used for "order-of-magnitude" values only.
Particle size distribution measurements were made at the scrubber inlet and
outlet. Four samples were collected at the scrubber inlet and five at the scrubber
outlet. Particle size fractions were analyzed gravimetrically. Because the Method 5
particulate matter tests were conducted at the same time the particle size
determinations were made, the results can be used in the development of particle
size-specific emission factors.
4-4
-------
4.1.5 References 9 through 13
These are the results of five particulate matter emissions compliance tests
performed on five different sludge incinerators located at one treatment plant.
Each test was conducted in accordance with EPA Methods 1 through 5 and provided
controlled emissions data.
It was determined that the tests were generally of good quality. However,
original raw field data sheets, laboratory data sheets, and sampling train
calibration data were not included with the reports. For this reason, a rating of B
was assigned to the test data in these references.
4.1.6 References 14 and 15
These are reports of compliance tests conducted to determine particulate
matter emissions from two different sludge incinerators. Each test was performed
in accordance with EPA Methods 1 through 5 and provided controlled emissions
data. The quality of each test was generally good. However, in each case,
information pertaining to design operating parameters (e.g., sludge feed rate) was
not provided; thus, it could not be determined if the sources were operating within
typical ranges of these parameters. Therefore, the test data from these references
were assigned a rating of B.
4.1.7 Reference 16
Reference 16 is a particulate matter emissions compliance test report that
provides controlled emissions data. The tests were performed in accordance with
EPA Methods 1 through 5. The quality of the tests and process description
provided were good, and the information required was complete. A rating of A was
assigned to the test data.
4.1.8 References 17 through 20
References 17 and 18 contain the results of two compliance tests for one
incinerator. References 19 and 20 contain information from compliance tests for
two incinerators at another site. For each test, EPA Methods 1, 2, 3, and 5 were
used to provide controlled particulate matter emissions data.
4-5
-------
The quality of each test was good, and enough detail was provided for
adequate validation. The test data from each reference were assigned a rating of A.
4.1.9 Reference 21
Reference 21 is a source sampling report of testing performed concurrently at
the sludge incinerator scrubber inlet and scrubber stack to determine particulate
matter emissions and particle size distributions. The results of the EPA Method 5
tests provided controlled and uncontrolled particulate matter emissions data.
The tests were of good quality and all necessary data pertaining to process
descriptions and sampling and analytical data were provided. However, because
design parameters for the incinerator were missing, it is not known if the source
was operating within typical ranges for these parameters during the test. Because
of this, the data were rated B. Particle sizing was performed using a cascade
impactor attached to a probe on the Method 5 sampling train. The report presents
the scrubber collection efficiencies by particle size range.
4.1.10 References 22a through 22d
These compliance test reports present controlled particulate emissions data
for incinerators within the same metropolitan sewer district. The tests were
performed using EPA Methods 1 through 5. While the testing methodology appears
to be sound, all four reports lacked enough detail for adequate validation. Field,
laboratory, and calibration data were not provided in the reports. In addition, the
conditions under which the source was operated were not well documented. For
these reasons, each of the four tests was assigned a C rating.
4.1.11 References 24 and 25
These are reports of two particulate matter emissions compliance tests
performed on the same incinerator at different times. The testing methodology was
sound, and the level of detail of the documentation was adequate (except for
missing design parameters). However, the results of the tests, taken only 1 month
apart, show a wide deviation. Particulate matter emissions averaged
1.62 kilograms per dry megagram of sludge (3.25 pounds per dry ton of sludge) in
the first test and 0.36 kilograms per dry megagram of sludge (0.73 pounds per dry
4-6
-------
ton of sludge) in the second test. While there may be a reasonable technical
explanation for the deviation, none was provided. Therefore, each test was
assigned a C rating.
4.1.12 References 26 through 29
These are reports of compliance tests conducted on four different sludge
incinerators. Results are presented for controlled emissions of total particulate
matter, NOX (for References 26 through 28), SO2, acid gases (HC1 for References 26
through 28, and H2SO4 for Reference 27), and methane VOC. Reference 29 also
contains controlled CO emission data. Reference 28 contains controlled Pb and Hg
emissions data. Controlled metal emissions data are included in References 26
and 28 for As, Cd, Cr, and Ni. Metal emissions data from Reference 27 were not
used because, according to information obtained from the State agency, the results
were based on sludge analysis.
The testing methodology for each test appeared to be generally sound. Each
of the reports lacked sufficient detail for adequate validation of the results. Also,
this State requires front- and back-half collections to be included in particulate
matter emission results, and the reports did not include a breakdown of the
collections. The State agency was contacted for additional information including
dry feed rates for each of the test runs and weights for the front-half collections of
particulate matter.
Because raw data sheets, design feed rates, and other process data were
missing from the reports, each data set was rated B.
4.1.13 Reference 30
Reference 30 is a particulate matter emissions compliance test report.
Sufficient documentation was provided for validation and the testing methodology
was generally sound. However, the first run of the test was made with the
percentage of isokinetic nozzle velocity less than the desired minimum of 90. The
report discussion mentions this deviation and states that corrections were made for
this in the report. Nevertheless, it was decided that only the second and third runs
4-7
-------
would be used in determining the average emission value for this test. A rating
of B was assigned to the data.
4.1.14 Reference 32
This compliance report presented the results for particulate matter emissions
testing of one sludge incinerator. The testing methodology was sound and the level
of documentation was sufficient for validation purposes. However, background data
pertaining to the source operation and design parameters were not provided. For
this reason, the data were assigned a B rating.
4.1.15 Reference 33
Reference 33 is a particulate matter emissions compliance report for one
sludge incinerator. The tests were performed in accordance with EPA Method 5
and provided controlled emissions data. Complete background information and
testing details were provided. The data were given an A rating.
4.1.16 Reference 34n and s
This report presents the results of a source emissions survey conducted for an
incineration systems manufacturer. Testing was performed on two incinerators at
one site to determine particulate matter concentrations at both the scrubber inlet
and outlet. Tests at the scrubber inlet consisted of one run for each incinerator and
both back- and front-half collections were used. Three runs were used for each
outlet test, and the results were based on the front-half collections only.
The testing methodology was sound and the source process was described
adequately. Original field data, calibration information, and laboratory analysis
sheets were not included in the report. For this reason, the controlled (outlet) data
for each test were given a B rating. Uncontrolled (inlet) data were assigned a
D rating because the results were based on a single run. These data (using the
front-half collection results only) may provide an order-of-magnitude value for the
source.
Particle size distribution for uncontrolled emissions was determined using a
Coulter Counter. Results of particle sizing are presented in Reference 35b (a
duplicate of the particulate emissions test described in Reference 34).
4-f
-------
4.1.17 References 35a. 35c. 35d. and 35e
These are reports presenting emission data for four infrared sludge
incinerators. Each of the reports provides controlled particulate matter emission
data, and Reference 35e provides uncontrolled data as well. Reference 35e also
presents emissions data for NOX and SO2 before and after the control device.
The data are part of summary reports compiled for an incinerator
manufacturer, and background information was not included. Raw data, analytical
reports, sampling procedures, calibration information, and process descriptions
were missing. Because of these deficiencies, each of the tests was assigned a
C rating.
References 35a and 35e provided controlled and uncontrolled particle size
data. In the case of Reference 35a, the uncontrolled particulate size distribution
data were established 5 months after the particulate loading tests. Therefore, these
data cannot be used.
4.1.18 References 39 and 40
These reports are part of research projects designed to investigate the
performance of air pollutant abatement systems for controlling metals and organics
emitted from sewage sludge incinerators. The tests were conducted by an EPA
contractor to determine the efficiency of an ESP and a baghouse, respectively. In
each case, testing was done on incinerators with existing scrubber systems, and
slipstreams were used for experimental testing of the control devices. Because
comparative data were needed, the reports contain scrubber inlet and outlet data
representing emissions not controlled by the ESP or the baghouse. Controlled and
uncontrolled emissions data are provided in Reference 39 for particulate matter, As,
Cd, Cr, Pb, and Ni. Uncontrolled emissions data are presented for nonmethane
VOC's in both reports and for NOX, CO, and SO2 in Reference 39.
The methodologies were sound, and background information and
documentation provided were complete in both reports. Therefore, both reports
were assigned A ratings.
4-9
-------
Each report provides controlled and uncontrolled participate matter mass
concentrations by SASS size fractions.
4.1.19 References 42 through 44
These are particulate matter emission compliance reports for sludge
incinerators at three different sites. In each case, the methodologies were sound,
and appropriate background information and documentation were provided. Each
data set was given an A rating.
4.1.20 Reference 45
This is a particulate matter and sulfur dioxide emissions test report for a
sludge incinerator. The report provides controlled emissions data for each of these
pollutants. While the methodology used was sound, the report did not include
sufficient background information to establish the design feed rate value.
Therefore, a B rating was assigned to the data.
4.1.21 Reference 47
Reference 47 is a particulate matter emission compliance report for one
sludge incinerator. Method 5 procedure was used for the test. The report did not
include complete documentation for validation purposes, nor did it provide design
parameters for the source. Therefore, the data were given a rating of B.
4.1.22 References 48 and 49
These references are reports of two particulate matter emission compliance
tests for the same incinerator. The tests were done in 1982 and 1984. Each report
contained documentation adequate for validation, and the test methodologies were
deemed to be sound. An A rating was assigned to each.
4.1.23 References 53 and 54
These are reports of compliance tests performed on two different sludge
incinerators. The reports contain controlled emissions data for particulate matter.
Reference 53 also contains data for Hg emissions after the control device.
In each case, sound testing methodologies were used. However, each report
lacked enough detail for adequate validation, e.g., source manner of operation was
4-10
-------
not well documented. The State agency was contacted to determine dry feed rates
for use in emission factor calculations. Both reports were assigned a B rating.
4.1.24 References 67 through 72
References 67 through 72 comprise seven compliance tests on seven different
sludge incinerators. Each of the reports presents controlled particulate matter
emissions data. Other controlled emissions data reported include: Reference 68--
NOX, CO, and nonmethane VOC's; Reference 69-NOx, SO2, and methane VOC's;
References 71 and 72--NOx, and SO2-
Each of the tests was considered to have used sound testing methodologies,
and the reports included enough detail for adequate validation. The data were
assigned an A rating in each case.
4.1.25 Reference 75
This is a report of a compliance test performed on one incinerator and
provides controlled particulate matter emissions data. Sufficient process
information and field data were provided for validation of the results. However, no
information regarding the sampling procedures and test methodology was included
with the report. The State agency was contacted for this information and confirmed
that EPA Method 5 was used. The data were assigned a rating of A.
4.1.26 References 77 through 79
References 77 through 79 are reports of compliance tests performed on three
different sludge incinerators. Each test report provides controlled particulate
matter emissions data, and Reference 79 also provides controlled emissions data for
nonmethane VOC's. For each test report, the methodology was judged to be sound.
Each report included appropriate and complete background information with
details sufficient for validation. The reports were assigned A ratings.
4.1.27 Reference 80
This is a report of a compliance test performed on one sludge incinerator.
Controlled particulate matter emissions results are presented. Laboratory,
calibration, and field data sheets were provided, but information pertaining to the
4-11
-------
source process was not included. The State agency was contacted to obtain this
information. The data were assigned an A rating.
4.1.28 Reference 81
This compliance test report provides controlled emissions data for total
particulate matter. The testing methodology was judged to be sound, and adequate
detail was provided for validation. A rating of A was assigned to the data.
4.1.29 Reference 84
This test report provides controlled emissions data for noncriteria pollutants.
The report included original raw field data sheets, laboratory data sheets, sampling
train calibration data, and process data. The quality of each test was good. The
data from the reference were assigned a rating of A.
4.1.30 References 85. 86. 87. and 88
These four reports (Sites 1 through 4) were all prepared under the same
group of authors for the U.S. EPA Water Engineering Research Laboratory. Sites 1
and 2 are MHF facilities with venturi and impingement scrubber pollution controls.
During testing, Site 1 handled 0.45 to 0.91 megagrams (Mg) per hour [0.5 to 1 ton
per hour (tph)] of dry sludge feed, and Site 2 handled about 1.3 Mg/hr (1.5 tph).
Controlled data only were available for Site 1, while both uncontrolled and
controlled data were reported for Site 2. At Site 1, data collected were for
18 organic compounds, 5 metals, and total PM. At Site 2, data collected covered
20 organic compounds and 6 metals. Emission tests for metals were conducted for
short-term and long-term conditions. Results of long-term tests were given an A
rating. Results of short-term testing were assigned a B rating due to likelihood that
fluctuations of results would occur. All other thes results were assigned an A
rating.
Site 3 is a FBC with venturi and impingement scrubber pollution control
devices. The facility processed an average of 0.9 Mg/hr (1 tph) of dry sludge during
testing, and emissions data collected were for controlled emissions. Data collected
covered 10 semivolatiles and 5 metals and were rated A.
4-12
-------
Site 4 is another MHF. This facility used an afterburner, as well as venturi
and impingement scrubbers for air pollution control. The MHF was fed
approximately 0.5 Mg/hr (0.6 tph) dry sludge during testing. Pollutants were
sampled at 3 different locations: (1) uncontrolled emissions after the incinerator, (2)
emissions after the high energy scrubbers, and (3) emissions after the afterburner
and high energy scrubbers. Semivolatiles and metals data were collected for all
three operating conditions, and dioxins and furans data was collected for the third
operating condition. All data were rated A.
4.1.31 References 89. 90. and 91
All three of these reports present information on the same MHF facility
under a variety of test conditions. The facility is equipped with venturi and
impingement scrubbers.
Reference 89 presents two sets of tests on inlet and outlet emissions from the
venturi and impingement scrubbers during pilot-scale testing of a wet ESP and a
baghouse. Information was reported for 9 organic compounds during one set of
tests during the baghouse pilot-scale testing. Information was also reported for 19
organic compounds during one set of tests during the other set of tests conducted
during the ESP pilot-scale testing. The data from Reference 89 were assigned a
rating of A.
Reference 90 presents information on uncontrolled emissions from the
incinerator, and outlet emissions from the venturi and impingement scrubbers and
a wet ESP running in parallel. Information was reported for 24 metals in the
uncontrolled and controlled emission samples. The information from this reference
is rated B because some of the flue gas flow rates were calculated.
Reference 91 presents information on uncontrolled emissions from the
incinerator, and outlet emissions from the venturi and impingement scrubberss an
a fabric filter running in parallel. Information was reported for 24 metals in the
uncontrolled and controlled emission samples. The information from this sample is
rated A.
4-13
-------
4.1.32 Reference 92
This report summarizes tests done at the Crenston facility on a multiple
hearth furnace equipped with a venturi/impingement/afterburner for control. The
report included information on dioxin/furan emissions and emissions of five metals.
Because of the lack of background information, the data were rated C.
4.1.33 Reference 93
This report summarizes tests for dioxins and furans done on a multiple
hearth incinerator. However, emissions were not measured at detectible levels.
Therefore, results of this test report were not used.
4.1.34 Reference 95
Reference 95 presents information on tests done at a MHF using a venturi
scrubber for control. The report presents information on 27 metals, dioxins/furans,
and polycyclic aromatic hydrocarbons (PAH's) sampled at the venturi scrubber
outlet. The information from Reference 95 was assigned a rating of B because field
and analytical data sheets were not provided.
4.1.35 Reference 96
Reference 96 presents information on tests done at a MHF using a venturi
scrubber for air pollution control. Emissions from the venturi outlet were sampled
for 7 PAH's. The data from this report were assigned a rating of C because field
and analytical data sheets were not included, and inadequate detail of sampling
procedures was provided.
4.1.36 Reference 97
Reference 97 presents information on tests conducted at an FBC using
venturi and impingement scrubbers for air pollution control. Emissions of 5 metals
were tested at the outlet of the venturi/impingement control system. The data from
this report were assigned a rating of C because field and analytical data sheets
were not included in the report.
4.1.37 Reference 98
Reference 98 contains data for three MHFs and one FBC. Two of the MHF's
and the FBC are controlled with an impingement scrubber. The remaining MHF is
4-14
-------
controlled with a cyclone scrubber. A total of 24 metals were tested at the inlet to
and outlet from the control devices for the MHF's. Only outlet emissions from the
FBC were reported. The information from this reference was assigned a rating
of A.
4.1.38 Reference 99
Reference 99 contains data from tests done on one MHF using a
venturi/impingement system for air pollution control. The report presents
information on dioxins/furans, 11 metals, 15 semi-volatile compounds, CO, HC1,
and total PM exiting the scrubber system. The data were rated A.
4.1.39 Reference 101
Reference 101 is a test report on a MHF equipped with a cyclone/venturi
system for air pollution control. Testing on the outlet emissions from the
cyclone/venturi system was performed to determine the emissions of HC1, PM, 12
metals, dioxins/furans, PAH compounds, and 3 organics. Testing was performed
during normal incinerator operation conditions with sludge feed rates between 1.5
and 1.7 tph (dry basis). The data are rated A.
4.1.40 Reference 102
Reference 102 contains data from tests conducted at a MHF equipped with a
venturi/impingement control system followed by a wet ESP. Emissions of 9 metals
were tested at the exit from the venturi/impingement system and after the wet ESP.
Data from this report are rated C because no field or analytical data sheets were
provided to validate the numbers reported.
4.1.41 References 104. 106. 107. and 108
These four reports (sites 6, 8, 9 and 10) are a continuation of those conducted
in References 85-88 (sites 1-4). Sites 6, 9, and 10 are MHF facilities. Site 8 is an
FBC facility.
Reference 104 presented data on 5 metals, PM and CO sampled at the inlet
and outlet of a venturi/impingement air pollution control system. Two sets of
results are reported: sampling during low CO operation and sampling during
normal CO operation. The data from this reference are rated A.
4-15
-------
Site 8 is equipped with venturi/impingement scrubbers followed by a wet
ESP for air pollution control. Reference 106 presented data on 5 metals, SO2, NOX,
and CO sampled at the inlet to the venturi/impingement scrubbers, inlet to the ESP
(outlet from venturi/impingement), and outlet from the wet ESP. Also tested at the
inlet to the wet ESP were 14 organic compounds and dioxins/furans. The data from
this reference are rated A.
Site 9 is equipped with venturi/impingement scrubbers followed by a wet
ESP for air pollution control. Reference 107 presented data on 6 metals, PM, SO2,
NOX, CO, and organic compounds sampled at the inlet to the scrubbers, inlet to the
ESP, and outlet from the ESP. However, data on the organic compounds could not
be converted to an emission rate value because stack flow rates were not reported
for this sampling run. Two sets of results were reported: sampling during low CO
operation and sampling during normal CO operation. All other test data are rated
A.
Site 10 is equipped with a cyclone and venturi for air pollution control.
Reference 108 presented data on 21 organic compounds sampled at the outlet of the
control system. Three sets of data were reported: tests conducted at low, medium
and high THC levels. The data from this reference are rated B because field and
analytical data sheets were not included.
4.2 RESULTS OF DATA ANALYSIS
Emission factor calculations were made in terms of weight of pollutant per
weight of dry sludge incinerated. It should be noted that the terms "controlled" and
"uncontrolled" in this discussion are indicative only of the location at which the
measurements were made.
A summary of the particulate emission data discussed below is contained in
Tables 4-1 and 4-2. Tables 4-3 through 4-7 present summaries of criteria pollutant
(other than particulate matter) data, and Tables 4-8 through 4-55 contain
summaries of noncriteria pollutant data. Table 4-56 summarizes the data
presented in Tables 4-1 through 4-55.

4.2.1 Total Particulate Matter Emissions Data
Both uncontrolled and controlled particulate matter emission factors were
determined from the data contained in the reference documents described above. In
the case of uncontrolled emissions, References 5o, p, r; 7; 21; 34n and s; 35e; 39; 91;
98; 104; 106; and 107 contained useful data. For all of these except Reference 39,
the emission factors were determined from the test data by manual and computer
calculations from emission factors expressed in units other than mass of pollutant
per megagram of dry sewage sludge incinerated. For Reference 39, the appropriate
uncontrolled emission factor was extracted directly from the test report.
References 34n and s each contained a single-run value for uncontrolled p articulate
matter emissions. As discussed in Section 4.1.16, these emission results were used
as order-of-magnitude values only.
For controlled processes, a procedure similar to that described above for
determining uncontrolled emission factors was used. References 4, 5o through 5r,
7, 9 through 21, 22a through 22d, 24 through 30, 32, 33, 34n and 34s, 35a, 35c, 35d,
35e, 39, 49, 53, 54, 67 through 72, 75, 77 through 81, 84, 91, 98, 101, 104, 106, and
107 contained useful data. Except for References 4, 10, 11, 13, 15, 17 through
22a-22d, 23, 24, 25, 32, 33, 34n and 34s, 35c and 35d, 39, 42, 47, 48, 49, and 70, the
controlled emission factors were calculated from data presented in other terms. A
summary of all available p articulate matter emission factors is shown in Table 4-1.
4.2.2 Particle Size Data
Both uncontrolled and controlled p articulate matter emission factors were
determined from the data contained in the reference documents described above. In
the case of uncontrolled emissions, References 7, 21, 35a, 34n and s, and 35e
contained useful data. For controlled emissions, References 4, 7, 21, 35a, and 35e
contained useful data. A summary of all available PM10 emission factors is shown
in Table 4-2.

determined for both methane and nonmethane VOC's. References 68, 79, and 84
were used to determine controlled nonmethane VOC emission factors. References 6,
26 through 29, and 69 were used to determine controlled methane VOC emission
factors. Uncontrolled nonmethane VOC emission factors were determined from
data contained in References 1, 2, 39, and 40. No data were available to develop
emission factors for uncontrolled methane VOC's. In all cases, the emission factors
were determined from the test data by calculations from emission factors expressed
in terms other than mass of pollutant per megagram of dry sludge incinerated. A
summary of VOC emission factors is shown in Table 4-3.
4.2.3.2 Lead. Controlled Pb emission factors were determined from the data
contained in References 4, 5o through 5r, 28, 39, 84 through 88, 90 through
92,95,97 through 99, 101, 102, 104, 106, and 107. References 39, 85, 86, 88, 90, 91,
101, and 102 contained uncontrolled emissions data. None of the data reports
indicated that Pb emission values were based on data from lead compounds.
Therefore, elemental Pb was assumed in each case. Because the lead emission
factor is the sum of both front- and back-half catches, the lead emission weight
cannot be compared to the particulate matter emission weight.
In each case, calculations were performed to convert from the units used in
the reports to conventional emission factor units. A summary of Pb emission factors
is shown in Table 4-4.
4.2.3.3 Sulfur Dioxide. Oxides of Nitrogen and Carbon Monoxide. Data for
determining uncontrolled emission factors for SO2 were taken from References 1, 3,
5o, 5p, 5r, 35e, 39, 98, 104, 106, and 107. Controlled emissions data used to
determine SO2 emission factors were taken from References 5o through 5r, 26
through 29, 35e, 45, 69, 71, and 72. Because water based scrubbers offer virtually
no control of NOX or CO emission factors for these pollutants were determined by
using both uncontrolled and controlled test data. Uncontrolled emissions data for
4-108
-------
NOX were available from References 1, 3, 35e, 39, 106, and 107; and for controlled
emissions data from References 26 through 28, 35e, 68, 69, 71, 72, 98, 99 and 106.
Uncontrolled emissions data for CO were available from References 1, 3, 39, 84, and
106.; and for controlled emissions data from References 29, 68, 72, 99, 101, 104,
106, and 107. The emission factors were determined from the test data by
calculations. Tables 4-5 through 4-7 present a summary of emission factors for
those pollutants.
4.2.4 Noncriteria Pollutant Emissions Data
4.2.4.1 Acid Gases. Reference 5o, 5p, 5r, 98, and 99 contained data for
uncontrolled acid gas (H2SO4) emissions. References 5o through 5r, 27,98, and 99
provided data for the determination of controlled emission factors for H2SO4.
References 26 through 28, and 99 were used for emission factors for HC1.
Calculations were required to convert into conventional emission factor units. A
summary of acid gas emission factors is shown in Table 4-8.
4.2.4.2 Organic Compounds. References 1, 2, 3, 84, 88, 99, and 106 were
used for the development of controlled emission factors for several dioxin and furan
compounds. Tables 4-9 through 4-14 present summaries of dioxin and furan
emission factors. References 85, 86, 87, 88, 89, 99, 101, 106, and 108 were used for
the development of controlled and uncontrolled emission factors for other organic
compound emissions, including acetaldehyde, acetone, acrolein, acrylonitrile,
benzene, butadiene, carbon tetrachloride, ethylbenzene, formaldehyde,
perchlorolethylene, styrene, toluene, vinyl chloride, and xylene. These emission
factors are listed in Table 4-17 through 4-35.
4.2.4.3 Inorganic Compounds. References 4, 26, 28, 39, 86 through 92, 99,
101, 102, 106, and 107 provided emissions data for arsenic (As). References 86, 99,
104, and 106 provided emissions data for beryllium (Be). References 4, 5o-5r, 7, 26,
28, 39, 84, 85-88, 90, 91, and 97-102 presented cadmium (Cd) emissions data.
References 4, 5o-5r, 26, 28, 39, 84, 85 through 87, 89 through 92, 95, 97 through
100, 102, 104, 106, and 107 presented data for chromium (Cr). Mercury (Hg) data
4-109
-------
were presented in References 28, 53, 95, 99 and 101. Nickel (Ni) data were
presented in References 5o, 26, 28, 39, 84 through 92, 97 through 102, 104, 106, and
107. References 89, 90, 91, 95, 98 and 99 presented emissions data for aluminum
(Al), barium (Ba), calcium (Ca), iron (Fe), magnesium (Mg), silver (As), sodium
(Na), and titanium (Ti). References 90, 91, and 98 presented emissions data for
antimony (Sb) and phosphorous (P). Emissions data for manganese (Mn) and zinc
(Zn) were provided in References 89, 90, 91, 98, 99 and 101. Gold (Au) and sulfur
(S) emissions data were presented in References 89 through 91. Potassium (K) and
silicon (Si) data are presented in Reference 98. Cobalt (Co) and tin (Sn) data are
presented in References 89, 90, and 98. Copper (Cu) emissions data were presented
in References 88 through 92, 97 through 99, 101, and 102. References 90, 91, 98,
101, and 102 presented selenium (Se) data, and References 89 through 91
presented emissions data for vanadium. Summaries of emission factors for
inorganic compounds are presented in Tables 4-36 through 4-55.
4.3 ENGINEERING METHODOLOGY
The emission data were averaged as the arithmetic mean of different
sampling runs prior to inclusion in the data base. Test programs at most facilities
consisted of three sampling runs conducted during distinct and controlled normal
operating conditions.
Due to the variety of formats used to report units of measure at different
sludge incineration facilities, the emission data required some preprocessing to
standardize the units of measure prior to computer calculation of emission factors.
Emission factors were then calculated in terms of kg/Mg of dry sludge and Ib/ton of
dry sludge for all pollutants. The list of conversion factors used is included as
Table 4-18.
If the pollutant-specific data, Dl, were reported in ng/dscm corrected to
12 percent CO2 in the test report, the following calculation:
DI = Dl * (percent concentration of CO2)/12
4-110
-------
was performed to present the "uncorrected" value in the resulting table. When the
data, Dl, were reported in ng/dscf in the test report, the conversion
D1=D1*35.31
was required to present Dl as ng/dscm. Acid gas and criteria pollutant data were
presented in ppmdv corrected to 12 percent CO2- In order to convert data, Dl, from
mg/dscm corrected to 12 percent CO2 to ppmdv at 12 percent CO2, the following
relation was employed:
Dl * (1000 * 0.02404)
Dl =
(molecular weight of pollutant!
Calculation of emission factors was performed using conversion factors (CF's)
to relate process conditions to emission concentration levels. The CF's were
calculated manually for each facility that provided percent concentration of CO2,
process feed rate, and stack gas flow measurements. The emission factors in 10-10
Ib/ton were calculated using the "corrected" concentration data in English units, El
in 10-10 gr/dscf, and the following equation:
EF = CF*E1
where:
CF = (Percent concentration of CO2)*(stack gas flow in
dscfm)*(7.14xlO"4)^-process rate in ton/hr;
The emission factor in //g/Mg were then calculated using:
EF in //g/Mg = (EF in 10"10 Ib/ton) * 0.05
In order to calculate emission factors from data presented in ppmdv at 12 percent
SO2, a second conversion factor, CCF, was needed. CCF was defined as:
4-111
-------
._„ _ (molecular weight of pollutant) (1.3 x 10~8 ) (CF)
LLi -
(7.14 x 1(T4)
An emission factor value may be calculated from:
EF in Ib/ton feed = (Dl in ppmdv @ 12 percent CC>2)(CCF)
Because test periods were nonsimultaneous, CF values for some facilities were
different for the various pollutants. Determinations of emission factors were made
only when process feed rates were documented or derivable from plant records of
sludge process rates.
