                            EXECUTIVE SUMMARY
     Numerous studies in states and metropolitan areas in the United States
have demonstrated the existence of sources of toxic air pollutants  ("air
toxics") emissions.  The potential health impacts of these emissions can
include both cancer and non-cancer effects.  To investigate the existence
of potential sources of air toxics emissions in Iowa, the State of  Iowa
Department of Natural Resources (DNR) requested assistance for a study
from the U.S. Environmental Protection Agency.  On the basis of prelimi-
nary emissions estimates and other factors such as pollutant toxicity,
population proximity, and release height, the study was designed to rank
the sources identified in relative order of importance as the basis for
recommendations for additional, focused air toxics program development
activities.

     Several results became apparent after a variety of information sour-
ces were reviewed, and a wide range of facilities (including landfills,
wastewater treatment plants, hazardous waste treatment, storage disposal
facilities, and area sources) were analyzed.  First, area sources including
mobile sources (motor vehicles) have a relatively important impact  in Iowa.
Second, there is a sizable group of facilities which could be significant
air toxics sources in Iowa which are not documented in the computerized
emission inventory system kept on other air pollution sources.  Finally,
the known air toxics point sources in Iowa prior to this study did  rank
as relatively important sources.

     Based on these trends and the ranking of sources, five recommendations
are being made.  In summary, these recommendations are:

     1.  Expand efforts to develop a statewide VOC inventory - There appear
         to be a number of significant VOC (and air toxics) sources missing
         from the State's emission inventory; expansion of the VOC  inventory
         would thus help to close this gap in the data base for analysis
         of air toxics.

     2.  Selectively send emission inventory questionnaires to "high risk"
         sources - It does not seem justified at this time to initiate a
         comprehensive statewide survey; however, this study has identified
         a number of sources (including VOC sources mentioned above) for
         which comprehensive air toxics emissions data would be useful.

     3.  Perform a more in-depth assessment of selected non-traditional
         sources - Although non-traditional sources of air toxics (includ-
         ing landfills and publicly owned treatment works) were not the
         highest ranked sources in this study, the data utilized was rather
                                    VI

-------
    limited; therefore looking at selected non-traditional sources to
    ascertain their potential impacts is needed for a more in-depth
    analysis.

4.  Develop pilot risk assessment program - A pilot risk assessment
    program is strongly recommended; it would not only provide a means
    for evaluating the potentially "high risk" sources mentioned above,
    it would also provide a starting point for possibly including a
    form of risk assessment in permit reviews in the future.

5.  Review selected source categories - Additional source categories
    known to be in Iowa and which need investigation include sterili-
    zing operations (such as those in hospitals), grain fumigation,
    and chrome plating.

                                CHAPTER 1

                               INTRODUCTION
     There has been a recognition for some time that specific air pollu-
tants can have detrimental impacts on human health.  While National Am-
bient Air Quality Standards (NAAQS) have been set by the U.S. Environmen-
tal Protection Agency (USEPA)  for "criteria" pollutants (i.e., those for
which health-based criteria have been formally defined), "non-criteria"
pollutants, or "air toxics", can also have harmful effects.  Depending on
the pollutant, these effects may or may not be well documented.  Since the
passage of the Clean Air Act Amendments of 1970, the main mechanism for
controlling such hazardous air pollutants has been Section 112 through
National Emission Standards for Hazardous Air Pollutants (NESHAPs).  After
a pollutant is officially "listed" by USEPA, regulations for specific
source categories are to be adopted.  As of 1986, source category regula-
tions had been adopted for radionuclides, beryllium, mercury, vinyl chlo-
ride, benzene, asbestos, and arsenic.  Coke oven emissions have also been
listed as a NESHAPs pollutant.

     Because NESHAPs only cover a very limited number of facilities and
pollutants, many state and local agencies have committed themselves to
reviewing and analyzing the health impacts of additional air toxics with-
in their jurisdictions.  In a simplified form, these health impacts from
air toxics can be classified into three groups:

     o  Cancer - Cancer effects of specific air toxics are generally
        understood to be dependent on both the degree of exposure to
        a carcinogen and that carcinogen's potency.  While many models
        have been proposed to describe the process of carcinogenesis,
        analysis of cancer effects have in general included the assump-
        tion that there is no safe "threshold" exposure or concentra-
        tion of a carcinogen.

     o  Long-term non-cancer effects - Some pollutants may cause a speci-
        fic effect other than cancer, such as toxicological impairment
        of certain organs of the human body or detrimental reproductive
        effects.  Frequently, threshold exposures or concentrations may
        be determined for such effects.

     o  Acute toxic effects - Large instantaneous pollutant releases in
        occupational environments are usually associated with accidents.
        Acute toxic effects are the result of short term elevated concen-
        trations of specific pollutants.  The 1984 catastrophe at the Union
        Carbide plant in Bhopal, India, is the most well-known example of
        acute toxic effects of hazardous air pollutants.

                                    1-1

-------
     Putting together an air toxics program requires conscious planning
towards minimization of these detrimental health effects, and such plan-
ning of necessity entails a review of the sources which could have an im-
pact on a specific population.  In an era of very limited resources for
many State and local air pollution control agencies, identification of the
facilities most likely to cause such health effects first not only aids in
the effort to protect public health, but also provides the opportunity for
agencies to focus and prioritize available staff activities.  Creating an
emissions inventory is frequently a good first step towards determining the
extent and nature of the air toxics problem in any State or local area, but
like any other part of an air toxics program, emissions inventory develop-
ment must be carefully planned to avoid wasted effort and funds.

     It was in this context that the Iowa Department of Natural Resources
(DNR) decided to perform an initial air toxics emission inventory.  To aid
them in this effort, Iowa DNR asked USEPA Region VII for assistance in de-
veloping an inventory which utilized multiple information sources to iden-
tify both traditional and non-traditional sources of air toxics.  Accor-
dingly, in June of 1985, Engineering-Science (ES) was issued a work assign-
ment (No. 33 of Contract No. 68-02-3888) which directed ES to develop a
screening and prioritization plan based on the following data bases and doc-
uments:

     o  Iowa DNR's Emission Inventory System/Point Source (EIS/PS)
        computerized emission inventory data base

     o  Pre-treatment agreements between major industrial users and
        Publicly Owned Treatment Works (POTWs)

     o  Iowa DNR's landfill files

     o  RCRA generator files (through July 1985)

     o  The SRI International 1985 Chemical Producers Directory

     o  The Directory of Iowa Manufacturers (1985)

     o  Background files from Iowa DNR on Section 111(d) and NESHAPs
        sources

     o  Hazardous waste treatment, storage, and disposal (TSDF)
        summaries from Iowa DNR

Certain area sources and mobile sources were also reviewed.

     This final report documents the results of the project and provides
recommendations for further emission inventory related activities to aid
in the development of an air toxics program.  The report includes a des-
cription of the procedures used (Chapter 2), a characterization of the
data bases reviewed (Chapter 3), an explanation of the results (Chapter
4), and a section on conclusions and recommendations (Chapter 5).  A des-
cription of key facilities and suggested questionnaires for an air toxics
emission inventory survey are provided as appendices.

                                CHAPTER 2

                                PROCEDURES
     Emission inventories have traditionally been ah integral part of air
pollution control planning programs.  Comprehensive inventories have been
instrumental in identifying and quantifying numerous emission sources which
can have an impact on the attainment and maintenance of the,National Am-
bient Air Quality Standards (NAAQS).  As concerns about air toxics have in-
creased, air toxics emission inventories have frequently been used as a
starting point for the development of air toxics programs.  Clearly though,
the approach taken to developing an air toxics inventory must be substan-
tially different than the approach used for a criteria pollutant inventory.
First, there are many more pollutants which must be considered, and in most
cases there are fewer sources of any specific pollutant.  In addition, the
toxicity may be greater than with criteria pollutants; as a result, rela-
tively "small" sources can under certain circumstances be relatively impor-
tant from a health perspective.  Finally, sources of air toxics may include
facility types which typically have not been included in air pollutant in-
ventories in the past.

     Because of these differences in the types and characteristics of
sources of air toxics and criteria pollutants, procedures for creating an
air toxics inventory must be carefully planned.  Experience in previous
emission inventories for" air toxics has provided indications that a vari-
ety of information sources can aid in the identification of potential air
toxics sources.  For example, if generator information is available as a
result of reporting requirements from RCRA, specific wastes may provide
evidence of a particular process which is known to be an air toxics source.
Therefore, it was determined in performing the first comprehensive air
toxics inventory in the State of Iowa that a thorough screening and prior-
itization of sources should be completed before any emission inventory sur-
vey forms would be sent to individual industrial facilities.  Figure 2-1
illustrates the general approach taken.
GENERAL APPROACH

     In order to take the widest possible view of potential (air toxics)
sources in Iowa, it was important to meet three goals:

     o  Identify air toxics emissions from sources that are documented as
        criteria 'pollutant sources;
                                    2-1

-------
     o  Determine potential air toxics emissions from sources for
        which indirect information is available (such as publicly
        owned treatment works); and

     o  Develop a methodology for identifying facilities that are
        not specifically documented in any data base.

It was recognized that identifying potential sources in this way does not
necessarily identify significant sources; rather it identifies "sources"
that can then be prioritized according to their potential significance.

     Significance for this study was defined as potential carcinogenicity
or other potential health effects.  As discussed above, impact on an
affected population depends on emissions, toxicity of the pollutant, and
the characteristics of the pollutant's release.  Accordingly, the proce-
dures below describe how information sources were screened, how emissions
were calculated for facilities in each of the three groups described above,
and how emissions (and therefore facilities) were prioritized.  The priori-
tization performed then was the basis for the recommendations included in
Chapter 5.

INFORMATION SOURCES REVIEWED

     There were eight main information sources that were reviewed for
this study in order to identify potential sources:

     1.  Iowa's EIS/PS - EIS/PS (Emission Inventory System/Point Source)
         contains the State of Iowa's computerized data base of emission-
         related data.  Iowa DNR developed a statewide emission inventory
         with questionnaires during 1983-1984, and sources have been up-
         dated on a case-by-case basis since then.  Emissions of air
         toxics may result either from particulate sources or from VOC
         sources.

     2.  Pre-treatment agreements between major industrial users and Pub-
         licly Owned Treatment Works (POTWs) -  In eighteen of the largest
         metropolitan areas within Iowa, industrial contributors to POTWs
         sign agreements to limit certain "priority pollutants" going to
         POTWs.  Pre-treatment agreements based on these limitations are
         then developed between the municipal operators and Iowa DNR.
         Waste streams entering POTWs may contain VOCs, and VOCs may vola-
         tilize or be stripped from these waste streams.  Therefore, VOCs
         entering a POTW may result in air toxic emissions.

     3.  Iowa DNR landfill files - Landfills may produce air toxics
         emissions in two ways.  First, municipal refuse may include a
         small proportion of waste solvents which volatilize within a
         landfill, either with or without soil cover.  Second, prior to
         the passage of laws regulating the generation and disposal of
         hazardous waste, hazardous waste was occasionally deposited
         into municipal landfills.  Emission rates are maximized when
         gas is generated within a landfill.
                                    2-3

-------
     4.  RCRA generator files -  Until July 1985,  Iowa DNR was responsible
         for the regulation of the generation and  disposal of hazardous
         wastes under the Resource Conservation and Recovery Act (RCRA).
         As a result, DNR files document inspection of facilities, and a
         computerized data base of the types of wastes generated at parti-
         cular facilities until that time.  Waste  codes can indicate the
         possible existence of particular types of emission sources.

     5.  The SRI International 1985 Chemical Producers Directory - Because
         individual chemical manufacturing plants  can be important air
         toxics sources, the SRI International 1985 Chemical Producers Di-
         rectory was checked to ensure that potential sources were fully
         identified.

     6.  The Directory of Iowa Manufacturers - Industrial directories com-
         monly list individual industrial facilities by county, and by
         other classifications.  The key classification for screening pur-
         poses is the type of manufacturing at a facility.  Specific pro-
         ducts can determine the types of processes necessary, the types
         of sources present, and the type of pollutants emitted.

     7.  Iowa DNR files on 111(d) and NESHAPs sources - Sulfuric acid mist
         and fluorides must be regulated from specific sources under Sec-
         tion 111(d) (e.g., phosphate fertilizer plants and sulfuric acid
         plants).  Iowa DNR has contacted these plants in the past.

     8.  Iowa DNR hazardous waste treatment, storage and disposal faci-
         lity (TSDF) files - When hazardous waste  is treated or handled,
         air toxic emissions can result, particularly \TOC.  Under RCRA,
         TSDFs are regulated, and. the amount of hazardous waste activity
         at a TSDF can determine its emissions.

These eight references were chosen because they cover a broad range of po-
tential information for criteria pollutant-emitting facilities, non-tradi-
tional sources, and other sources which have not previously been documen-
ted for any reason.  Table 2.1 shows the sorts of  information available
from the eight references reviewed.  It was recognized that the informa-
tion available from these references would (and should) overlap to a cer-
tain extent.  The next section describes how the information from these
references was screened and how emissions were calculated on the basis of
the information and data available.

     In addition to the basic references reviewed  above, other information
related to dry cleaners, service stations, and major arterial roadways
was gathered for the purpose of calculating emissions from "typical" area
source facilities.  A number of different governmental and non-governmental
organizations were contacted, including:

     o  Iowa Department of Job Services
     o  Iowa Department of Motor Vehicles
     o  Iowa Department of Revenue
     o  Iowa Department of Transportation

Generally, the approach utilized was to obtain data which was consistent
with available emission factors so that emissions could be calculated.  For
the purpose of obtaining emissions, a representative dry cleaner, gasoline
station, and major arterial were to be defined on the basis of information
gathered.

     It must be emphasized that all screening and emission calculations
were based on existing information.  1985 information was used whenever
possible, but when 1985 information was not available, other data (gene-
rally 1982, 1983, or 1984 data) was utilized.  As a result, emissions may
not be strictly representative of recent conditions at individual facil-
ities.  However, such inconsistencies were accepted as a part of the de-
sign of the analysis.  The emphasis of the analysis was to maximize the
potential sources considered, and not to spend substantial time on emis-
sion estimates at any one facility.
SCREENING OF REFERENCES AND CALCULATION OF EMISSIONS

     At the beginning of this study, it was recognized that there is a
diverse range of operations which may in fact be air toxics sources.  (As
discussed above, the fact that an operation is a source of air toxics may
not mean that it is significant in comparison to other air toxics sources.)
Among the sources which were considered in this assessment include those
listed in Table 2.2.  The purpose of reviewing a variety of references
was to identify potentially significant air toxics emitting facilities with
one or more of these sources.

Identifying Facility Operations

     This study was focused specifically on screening of information, and
as such was not oriented towards in-depth analysis of any one facility.
Elimination of a facility at one step in the analysis does not necessarily
mean that that facility might not be identified in another part of the
analysis.  As such, the study as a whole may in fact leave out some facil-
ities that deserve further analysis.  Nevertheless, with many potential
opportunities for facility identification and emission calculation, the
probability of omitting signficant facilities is minimized.

     In each case, there was an attempt made to identify operations at a
particular facility.  Emission sources at a facility may include:

     o  Process sources
     o  Fugitive sources
     o  Storage tanks
     o  Material handling losses
     o  Solvent evaporation
     o  Combustion sources                    „
     o  Area sources (e.g. surface impoundments)

Different references may include information on different sources.  For
instance, surface impoundments may not be included in EIS/PS/ but they
will be included in files on hazardous waste treatment, storage, and
disposal facilities.  Included here in Appendix B are summaries of what
was found at a group of major facilities in Iowa.  This information was
screened and used in the following way.

EIS/PS

     Iowa's EIS/PS was perhaps the single most important reference used.
Based on the VOC Species Manual (DSEPA/OAQPS, 1980) and other sources, a
list of priority Standard Industrial Classification (SIC) codes (Office of
Management and Budget, 1972) and Source Classification Codes (SCCs) (USEPA/
OAQPS, 1985c) were developed.  These SICs and SCCs are presented in Tables
2.3 and 2.4.  A series of retrieval runs was then performed on Iowa's com-
puterized master file, resulting in a set of emission points.

     Emissions were then calculated in several ways.  For VOC sources, the
VOC Species Manual was used to calculate specific air toxic emissions for
SCCs which were documented.  Other VOC emission points were reviewed for
other identifying data or information which could be used to characterize
the operation.  For example, degreasers often are coded with SCCs which
specifically designate the degreasing solvent used.  In addition,  during
the 1983 statewide emission inventory survey, industrial facilities were
asked if they handled or emitted any of a list of more than forty sub-
stances.  Similarly, for sources in Linn County, ES used summaries of
field investigations to determine how VOC emissions should be speciated
(USEPA Region VII, 1979).  For fuel combustion sources, particulates were
broken down into trace elements which are found in fuel oil and coal
(USEPA/OAQPS, 1982).

     In summary, emissions were calculated using available reference
material whenever possible.  Specific references were used on a case-by-
case basis (USEPA/OAQPS, 1983a, and USEPA/OAQPS, 1984) to obtain emission
factors whenever possible.  Emphasis was placed on calculation of emissions
for the maximum number of sources.

Publicly Owned Treatment Plants Pre-treatment Agreements

     For the purposes of this study, none of the POTWs were screened out
initially, as there were only nineteen to review.  The pretreatment agree-
ments focused most on heavy metals (which are also priority pollutants).
It was recognized at the beginning that estimating emissions from indivi-
dual POTWs based on plant-by-plant data was going to be difficult, because
of the probable lack of plant-specific VOC data.

     As a result, while the POTWs were individually reviewed for such
characteristics as specific processes (aeration activity, especially),
they were also analyzed as a whole to determine what typical values
could quantitatively define POTWs in Iowa.  Table 2.5 lists the POTWs
reviewed.  Similarly, the pretreatment agreements were reviewed for any
indications of specific industrial wastewater treatment that could be
the source of air toxics.

     Calculating emissions from POTWs can be a complicated undertaking,
and attempting an in-depth data search was beyond the scope of this study.
As a result, a simplified approach was taken to assess emissions from the
nineteen POTWs.  Figure 2-2 presents a basic approach for tracing potential
POTW emissions associated with influent, effluent, and residual sludge.  If
a mass balance is performed on an individual material, the emissions of
that material may be expressed simply as:

     EA  -  CAV - CA'V<

     where:  EA         = Emission rate of material A
             CA and CA' = Incoming and exiting concentrations of the
                          material in the process streams
             VA and VA" = Incoming and exiting volumentric flow rate of
                          material A in the process streams

In the simplest of cases, if all of the material is lost in the process,
the equation then reduces to:
Emissions were calculated in this way if no other data were available.

Landfill Files

     Emissions from landfills may result from two main routes:  diffusion
and convection.  Diffusion is minimized with soil cover, while convection
is maximized when landfills are the site of codisposal, i.e., a landfill
where hazardous waste and municipal waste are disposed of at the same site.
Codisposal maximizes emissions because hazardous wastes frequently contain
organics which volatilize, while methane and other gases are generated as
municipal waste ages.  This phenomenon provides a mechanism for volatilized
organics to be transferred to the surface.  Therefore, Iowa's landfill
files were reviewed for a number of different parameters, including surface
area, volumetric deposition rate, and indications of disposal of hazardous
waste.  Generally, it was expected that codisposal has been greatly reduced
if not eliminated as a standard practice.

     Counties for which landfills were reviewed are listed in Table 2.6.
These counties are generally those which include the greatest concentra-
tions of population in Iowa.  Special waste authorizations for these land-
fills were studied to determine if any specific volatile organic wastes
had been deposited.

     In many cases, it was expected that insufficient data would be avail-
able to utilize emission estimation equations for landfills (see for exam-
ple, USEPA/OAQPS, 1984).  In this case, a default value of 0.13% (American
City and County, 1983) of refuse was assumed to be hazardous waste, broken
down into 60% perchloroethylene, 20% toluene, and 20% xylenes.  Emission
rates were then calculated using the following emission rate equation:
        = 6Di Cgi A PT 4/3 (1/LHW.j/W)
                                    2-16

Default values based on a selection of published data was used when data
was not available (e.g., for diffusion coefficients).

RCRA Generator Data

     RCRA generator data was broken down into several parts.  Each part was
reviewed for potential information which could characterize operations and
processes at individual facilities.  The information that was considered
for this review were specific process descriptions,  many of which it was
hoped would be included on fiche (from Iowa DNR) for specific facilities.
Because of the voluminous nature of the fiche files  for Iowa, and because
it was known that substantial amounts of marginally relevant material for
emissions calculations was included within the fiche files, this informa-
tion was primarily used as a back-up reference.  (The fiche was not re-
viewed as a primary source for data for emission estimates.)  Generator
summaries were reviewed for unusual waste codes which would indicate spe-
cific processes at specific facilities.

SRI International 1985 Chemical Manufacturers Directory

     The SRI International 1985 Chemical Manufacturers Directory was used
in several ways.  First, the facilities that were identified for Iowa
counties were reviewed to eliminate producers of simple industrial gases
(such as acetylene) and distributors of certain chemically-based products.
Sources were cross-referenced against the Directory of Iowa Manufacturers
(Manufacturers News, 1986) to determine the primary SIC for that facility,
and to determine if any potential chemical manufacturers (which are likely
sources of air toxics) had been omitted frcm other data bases.

Directory of Iowa Manufacturers

     The Directory of Iowa Manufacturers was used as a check on the ade-
quacy of other data bases reviewed.  The same set of priority SIC codes
used to review EIS/PS (Table 2.3) was used to screen the Manufacturers
Directory.  Newly identified facilities that could not be eliminated for
any reason were then assigned emissions values based on an emissions/em-
ployment ratio, developed from facilities in identical SICs that were
documented in EIS/PS.  The formula used to assign emissions values is:

         Qij -
                                    2-19

-------
     where:  ^j = Emission rate for pollutant i and facility j;
             Qi  = Average emission of pollutant i for the SIC grouping
                   of facility j in Iowa's EIS/PS;
             I2j  = Employment at facility;
             E   = Average employment for facilities in the SIC grouping
                   of facility j in Iowa's EIS/PS.

Iowa's 111(d) and NESHAPs Files

     Emissions estimates were taken directly from Iowa's files for the
facilities which had already been identified.  To ensure that no facili-
ties had been omitted, the Directory of Iowa Manufacturers was reviewed
for NESHAPs and 111(d) source categories.

Hazardous Waste Treatment Storage and Disposal Facility (.TSDF) Files

     These files were reviewed thoroughly for waste and handling codes.
Depending on the type and volatility of the waste, and mechanisms available
for estimating emissions, the emission factors presented in Table 2.1 were
utilized.

Mobile and Other Area Sources

     Area source data was not screened as such.  Rather it was gathered
from a variety of organizations as discussed above so that emissions could
be calculated from representative "unit" sources.  The procedures used are
described below.

     Dry Cleaners

     Emissions from dry cleaning facilities were determined in part by a
perchloroethylene use factor per dry cleaning employee (Engineering-
Science, 1985) of 149 galIons/employee-year.  In fact, there are other
solvents besides perchloroethylene (such as Stoddard solvent) which are
used in dry cleaning facilites; however, because there is a unit risk
factor for perchloroethylene, to be conservative it was assumed that no
other substance was emitted.  Based on 1277 dry cleaning employees and 191
dry cleaning facilities in Iowa (Bureau of the Census, 1985a), it could
be determined that a total of 2,563,000 pounds, per year were used.  AP-42
(USEPA/OAQPS, 1985a) specifies an emission factor of 27.5 pounds per 100
pounds used, yielding a total emission statewide of 352.4 tons per year.
Polk County and average facility emissions then were determined propor-
tionally against the number of facilites statewide, i.e. 35/191 and 1/191
of the statewide total.

     Service Stations

     Because AP-42 emission factors for service stations are dependent
on throughput, emissions statewide were determined by using the July 1984-
June 1985 throughput total of 917,115,803 gallons of gasoline (Rusk,
1986).  To apportion the total emissions to individual counties, registra-
tion of motor vehicles was obtained from the Iowa Department of Motor
                                    2-20

Vehicles (Landy, 1986), and total VOC emissions were apportioned accor-
ding to the proportion of the state's motor vehicles in each county.  Based
on 164 service stations in Polk County, an average station's emissions were
calculated, i.e. 1/164 of the Polk County total.  Benzene, xylene, and
toluene fractions were based on the VOC Species Manual (USEPA/OAQPS, 1980).

     Mobile Sources/Arterial Highways

     Calculating emissions from a "typical" arterial highway is dependent
on defining a length of highway to be analyzed.  To make the calculation
more meaningful, a specific arterial highway in Polk County was chosen.
Based on ten specific segments identified by the Iowa Department of
Transportation (Pencock, 1986), a set of simplified calculations was
performed to determine the maximum VOC emission for a particular segment.
Using a set of simplified emission factors (LDGV-1.725 g/mi, LDGT1-2.305
g/mi, LDGT2-2.012 g/mi, and HDGV-8.774 g/mi) based on emission factors from
MOBILE 3 (USEPA/OAQPS, 1985a), the segment chosen was Fleur Drive from
Grande to Locust in Des Moines, with a total average daily traffic (ADT)
of 54,600 vehicles per day.  VOC emissions were calcuated assuming a max-
imum of gasoline-fueled vehicle traffic (100%) with 97% of total vehicle
miles traveled being associated with light duty vehicles (Penncuck, 1986).
To calculate emissions of products of incomplete combustion of products
of incomplete combustion (PICs), all of the VMT associated with heavy duty
vehicles was assumed to be heavy duty diesel vehicle (HDDV) VMT.
PRIORITY RANKING OF FACILITIES

     Besides emission estimates, data needed for the priority ranking of
sources include data that indicate the potency of health effects of spe-
cific pollutants, population data by county, and release characteristics
(specifically stack heights).  Because excess cancer is such an important
impact, this analysis was split between carcinogens and non-carginogens.
For carcinogens, potency is.defined by the unit risk value* (represented
by the parameter U in the expressions used to generate screening values).
U values were obtained by reviewing summaries generated by the U.S. Envi-
ronmental Protection Agency's Carcinogen Assessment Group (CAG).  There
are currently 55 substances for which unit risk values have been generated.
Table 2.8 provides a list of all U values used.

     For non-carcinogenic health effects, analysis of potential impacts is
somewhat more difficult.  Analysis of such impacts in many states has been
performed using adjustments to Threshold Limit Values (TLVs)  published by
the American Conference of Government and Industrial Hygienists (ACGIH).
There are substantial methodological problems with such an approach, parti-
cularly given ACGIH's indication that TLVs should not be used in a general
   A unit value is defined as the probability of the occurrence of an ex-
   cess cancer due to a continuous exposure for 70 years to a unit concen-
   tration (e.g., one microgram per cubic meter) of a given substance.

way to determine acceptable ambient concentrations of particular pollutants,
However, as a starting point, TLVs can be used to develop acceptable inha-
lation values ("A" values).  Table 2.9 presents a summary of all of these
"A" values generated from TLVs and used in the S3 prioritization equation
(see below).  Waste codes utilized in this analysis are presented in Table
2.10.

     Population data was taken by county from July 1, 1984 census summaries
(Bureau of the Census,  1985a).  The effect of using this data versus 1980
data was that the air toxics impacts of sources in Johnson, Muscatine, and
Polk Counties were magnified, because these three counties were the fastest
growing in Iowa during these four years.  (Many counties actually lost popu-
lation during this time.)

     Utilizing this data, a priority ranking scheme was developed to take
into account these three parameters — emissions, toxicity, and popula-
tion — as well as release height-to account for dispersion.  Table 2.11
presents the screening value equations developed for the following screen-
ing values:

     S1 - Carcinogens (total)
     S2 - Carcinogens (within the county of release)
     S3 - Non-carcinogens

These equations were based on the following assumptions:

     o  toxicity is related to unit risk values and inhalation criteria
        developed by USEPA;

     o  population at risk (for S2 and S3) are within the county of
        release;

     o  dispersion increases as the square of the release height, and no
        effective dispersion because of stack height occurs until the
        stack is at least 25 feet tall.

Release height data was taken from EIS/PS for facilities documented in the
system.  If multiple points contributed to the total air toxics emissions
from a particular facility, then an average of the release height was taken.
If no release height was known for a particular facility, then it was as-
sumed that the release height was less than 25 feet.  It should be noted
that this assumption probably underestimates release height for certain
facilities (such as some of those found in the Directory of Iowa Manufac-
turers ) for which little, if any, specific information was known.

                                CHAPTER 3

                 CHARACTERIZATION OF INFORMATION SOURCES
     As expected, the quantity and quality of data and other information
sources varied.  In order to interpret the results of this analysis pro-
perly (see Chapter 4), it is important to understand the limitations of
the data that went into the analysis.

EIS/PS

     As previously discussed, EIS/PS was screened for certain Standard In-
dustrial Classification (SIC) codes and certain Source Classification Codes
(SCCs).  As a result, there were numerous points that were identified for
air toxics review.  Most of the points identified were for particulates; al-
though particulate sources can, of course, be significant air toxics sour-
ces, many of the particulate sources within the Iowa inventory were not
(e.g., grain handling operations).  When the Iowa point source inventory
was assembled in 1983-1984, the emphasis was on sources which had already
been identified (USEPA Region VII, 1984).  As a result, because relatively
few VOC sources were included in the list of facilities to receive question-
naires, the final EIS/PS inventory (at that time) was heavily weighted to-
wards particulate sources and fuel combustion sources.  This concentration
towards particulates was verified when questionnaire responses frequently
did not identify additional, new VOC emission points which might have been
anticipated at certain facilities.

     An additional piece of information available as a result of question-
naire responses in 1983 was whether facilities used or emitted any of the
materials on USEPA1s original "list" of 37 materials for study under
NESHAPs.  While many facilities did not respond at all, and some facilities
responded in a very limited way, a few facilities responded in great detail.
This information was useful on a case-by-case basis (for example, identify-
ing a particular solvent used in a degreaser).
PRE-TREATMENT AGREEMENTS FOR POTWS

     There are 126 priority pollutants for POTWs and many, if not most, are
VOCs.  However, the pollutants of greatest concern for POTWs for their con-
tinued successful operation are removal of heavy metals.  The Iowa pretreat-
ment agreements (nineteen in all) generally were based on an industrial sur-
vey of the users of the treatment plant.  The depth of these surveys varied
greatly, particularly in terms of what pollutants were contributed by which
facilities.  "Pretreatinent" in fact is something of a misnomer, because the
                                    3-1.

-------
the background documents did not identify what facilities actually treated
their wastewater prior to discharge to the POTW.  In addition, to the ex-
tent that they identified pollutants coming from particular industrial con-
tributors, the pollutants they identified were generally metals.  (Except
in specific instances, VDC is the pollutant of concern from wastewater
treatment operations).  As a result, pretreatment information gave virtual-
ly no indication of the potential emissions from industrial wastewater
treatment.  Because the typical incoming concentration of certain organic
constituents was available from certain POTWs, it was possible to indirect-
ly determine the potential air toxics emission potential of certain plants.

     To determine default values for POTW parameters, all of the POTWs were
reviewed.  The primary pollutants of concern were:

     *   Benzene
     *   1,1,1-trichloroethane
     *   1,1-diehloroethane
     *   1,1,2-trichloroethylene
     *   Chloroethane
     *   Chloroform
     *   1,2-transdichloroethylene
     *   Ethyl benzene
     *   Methylene chloride
     *   Dichloro-bromo-methane
     *   Perchloroethylene
     *   Toluene
     *   Trichloroethylene
     *   Phenol
     *   1,3-transdichloropropylene
     *   Acrylonitrile
     *   Acrolein

A range of concentrations was determined for each one of these pollutants,
based on reported values at the nineteen POTWs, and an overall average was
calculated.  Because there was generally insufficient data to perform an
in-depth analysis at each POTW, the following procedure was followed.

     1.  Organic content was assumed to be that reported by each POTW for
         each substance.  If no concentration was reported, then the con-
         centration was assumed to be the average of the range reported
         at Iowa POTWs.

     2.  100% of the organic content was assumed to be lost as a result
         of process at the POTW.
LANDFILL FILES

     Since the early 1970's, landfills in Iowa have been regulated by DNR
and its predecessor agencies.  Waste authorizations have been historically
required for "special" wastes, including certain hazardous wastes.  How-
ever, the extent to which volatile hazardous wastes were deposited prior
to 1970, or improperly deposited during the 1970's and 1980's is unknown.
                                    3-2

-------
Given the soil cover of the last fifteen years and the degree of documen-
tation in the files showing the regulatory control which DNR has exercised
over hazardous waste disposal, it is reasonable to expect that the chance
is minimal that there are significant undocumented volatile hazardous
wastes over the last fifteen years in Iowa landfills.  As a result, the
only landfill which should be expected to have potentially significant air
toxics emissions from undocumented waste would be Black Hawk County land-
fill (the only one in Iowa recently accepting hazardous waste).  As des-
cribed in Chapter 2, the air toxics potential of other landfills can be
estimated through analysis of other key parameters, such as throughput
rate.
RCRA GENERATOR FILES

     Information on hazardous waste generators came from three separate
documents:

     *  the biannual Iowa hazardous waste generation report;

     *  the computerized listing of waste generation by facility; and

     *  the actual files from Iowa DNR on generator compliance with RCRA.

As discussed in Chapter 2, hazardous waste generation data is only useful
to confirm other information about the processes at a plant.  Theoretical-
ly, specific wastes can indicate specific processes at a plant; however,
within Iowa no processes were identified in this way because hazardous
waste generation summaries did not include references to process-specific
wastes.  While the bulk of the RCRA files were comprised of inspection re-
ports and were not focused on particular processes; on a case-by-case ba-
sis, they were used to resolve discrepancies about operation at particular
facilities.

     As stated above, generator summaries offered very few clues as to the
specific processes at individual plants.  One general observation that can
be made is that there were a substantial number of facilities which (at
least as of 1984-1985) were generating halogenated solvents waste.  Such
wastes are frequently a result of degreasing, which frequently does not
show up in EIS/PS.  Degreasing solvents often include such substances as
trichloroethylene, perchloroethylene, and methyl chloroform (1 ,1 ,1-trichlo-
roethane),  three solvents that are frequently reviewed as potential air
toxics.  This situation suggests that there could be substantially more
emission sources of these substances than the current Iowa VOC inventory
would suggest.

50 and 100 entries for the State of Iowa.  Some entries, like Monsanto in
Muscatine,  list specific products (such as ABS resins) that determine what
raw materials and therefore what emissions could be expected at a particular
                                    3-3

facility.*  Others, such as facilities which produce certain inorganic in-
dustrial gases could be eliminated from further consideration, because their
processes generally do not involve air toxics.  Other possible facilities
were cross-referenced with the Directory of Iowa Manufacturers (see below).
The result of this review was that several facilities, such as Salsbury
Laboratories in Charles City, could not be eliminated from further consider-
ration as an air toxics source.
DIRECTORY OF IOWA MANUFACTURERS

     Review of the Directory revealed over 100 facilities within priority
SIC codes not included within EIS/PS.  By rtself, this result does not in-
dicate that there are numerous significant air toxic sources in the State.
Rather, it indicates that there is a substantial area which needs to be
investigated further, not only for air toxics, but also for VOCs.** The
original plan was to identify these potential facilities and develop1 "sur-
rogate" emission estimates based on employment and emission estimates that
had been made for EIS/PS facilities in identical SIC codes.  What had not
been expected was the number of the facilities which would be identified
in this way.  Machinery manufacturing (3523) and miscellaneous plastic pro-
ducts (3079) were among the SICs most heavily represented.  In addition,
many of the facilities were classified in SIC codes for which no facilities
were identified in EIS/PS; as a result, calculation of "surrogate" emission
estimates was not possible for these facilities (e.g. 2834 -pharmaceutical
manufacturing).  Nevertheless, there is a substantial group of facilities
that potentially could be as significant (in the sense of health impacts)
as facilities which have been previously documented as criteria pollutant
sources.
HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES FILES

     TSDF information for Iowa facilities generally reflects on-site treat-
ment and storage; disposal usually occurs off-site.  (The one apparently
significant disposal facility in Iowa for hazardous waste is the Black Hawk
County Landfill).  Most of the entries in the Iowa summaries are for stor-
age, and because storage time is limited on-site, air toxics emissions are
minimized on-site.

     Based on the emission factors used, air toxics emissions as a result
of the handling and processing of hazardous waste (see Chapter 2) for fa-
cilities in Iowa was very small.  The reason is that many of the facili-
ties have low throughputs in hazardous waste processes and the emission
factors themselves are generally not large.  The resulting air toxics
emissions estimates were nevertheless included in total emission estimates
for individual facilities.
*  The recent inspection report for the Monsanto facility, however, was
   used to define emissions for this study (USEPA/OAQPS, 1985b).

** Iowa DNR has already started this analysis; see February 1986 memo-
   randum regarding VOC sources in Iowa from John Vedder to George Welch.

IOWA DNR FILES ON 111(d) AND NESHAPS SOURCES

     Iowa DNR has previously surveyed specific known 111(d) facilities
and has fairly detailed emission estimates for these facilities.  No spe-
cific NESHAPs sources had been identified prior to this analysis, so the
Directory of Iowa Manufacturers was reviewed to determine if any potential
NESHAPs (and 111(d)) sources had been missed.  On the basis of this review,
Climax Molybdenum (Ft. Madison) could be further analyzed for possible
applicability of 111(d).
MOBILE SOURCES AND OTHER AREA SOURCES

     Several simplifying assumptions were made in the analysis of mobile
and other area sources.  For dry cleaners, the total emissions in the
State of Iowa were calculated using the assumption that 100% of- the sol-
vents used was perchloroethylene, and that average per employee solvent
use derived from Idaho data (149 gallons of solvent per dry cleaning em-
ployee) was appropriate for Iowa.  In fact, perchloroethylene on average
accounts for less than half the solvent used in dry cleaning.  Therefore,
though the single dry cleaning plant emission estimate may be representa-
tive for a perchloroethylene dry cleaning plant, the Polk County emission
estimate probably overstates the county's actual perchloroethylene emis-
sions.  Also though there is no reason to believe that Idaho dry cleaning
plants are significantly better than Iowa's, Iowa-specific data would of
course be preferable.

     With respect to service stations, it would be useful to know the
actual gasoline pumped county-by-county.  When a variety of Iowa govern-
mental and non-governmental bodies were contacted, this information was
not available.  Given the screening nature of this analysis, the indirect
method of apportioning statewide gasoline totals by county vehicle regis-
tration totals should give an acceptable approximation for purposes of
estimating emissions, but county-specific gasoline data would be preferable,

     Finally, the estimates here for mobile sources include many simplify-
ing assumptions.  Based on the relative importance of air toxics emissions
from mobile sources (see Chapter 4), a more in-depth analysis of mobile
source emissions (utilizing the most up-to-date emission factors and
correction factors) would probably be justified.
HEALTH DATA ("U" AND "A" VALUES)

     Generally, either unit risk values ("U" values) or acceptable inhala-
tion values ("A" values) were available for every pollutant for which emis-
sions were estimated.  For some pollutants both "U" and "A" values were
available (i.e., both the carcinogenic and non-carcinogenic effects of a
particular pollutant could be assessed).  However, it must be stressed
that unit risk values are only currently available for about 55 pollu-
tants.  The carcinogenic potential of certain pollutants cannot be as-
sessed at this time without a unit risk value (or the equivalent).  As a
result, summaries of S1 and S2 values in Appendix C must emit facilities
which emit only pollutants which are nominal non-carcinogens.  As more
unit risk value data becomes available, the analysis presented here could
be expanded.

                                CHAPTER 4

                                 RESULTS
     As described in Chapter 2, the results of S1 , 52, and S3 (or screen-
ing parameters 1, 2, and 3, respectively) were designed to give a rough
measure of the following descriptions of "significance":

     o  S1 - "total" carcinogenic potential, regardless of whether impacts
             occur within or outside the county where the pollutants are
             emitted (Table C. 1);

     o  S2 - "local" carcinogenic potential, within the county where the
             pollutants are emitted (Table C.2); and

     o  S3 - potential for noncarcinogenic effects (Table C.3)

All tables are presented in Appendix C.  In discussing and analyzing the
results of this analysis, several points need to be made.  First, this
analysis is based on screening.  As such, it is possible that some poten-
tially significant sources were inadvertantly eliminated early from con-
sideration.  (Given the overlapping nature of the data bases, this possi-
bility should be minimized.) Second, screening values will be dependent
on the amount of information available on a particular source.  This situ-
ation is true for emission estimates; if a facility has been thoroughly
studied, all potential emissions may have been identified, thereby maximi-
zing the chances for high screening values.  Finally, the actual numerical
scores associated with individual facilities should not be analyzed in
too much detail, because in many cases the input assumptions are rough
approximations.  Differences by orders of magnitude are probably signifi-
cant; differences of less than an order of magnitude may not be signifi-
cant.  For this reason, the results presented here are limited to two
significant digits.
EXPANDED ANALYSES

     The results presented in Tables C.1, C.2, and C.3 reflect expanded
analyses which were performed after the original analyses were completed.
Mobile and other area sources were looked at in two ways - as "unit"
sources (a single arterial highway, a single dry cleaner, and a single
service station) and as countywide sources in Polk County.  Both results
are included in the tables.  In addition, because of the large unit risk
value for products of incomplete combustion (PICs), multiple calculations
                                    4-1

-------
were performed to determine the sensitivity of the rankings to this key
parameter.  While exclusion of the effects of PICs does affect the rank-
ings, the overall impact was nominal, leaving the relative ranking very
similar to the ranking including the effect of PICs.  The tables presented
here include the PICs contribution.
DISCUSSION

     A review of the results in Tables C.1, C.2, and C.3 shows that the
potential impact of certain area sources (particularly mobile sources and
service stations) within Iowa could be significant when compared to other
sources in the state.  Within S1 (the first screening parameter) among the
noteworthy sources were two chemical companies, an electronics firm, four
coal-fired power plants, one John Deere plant, a cement plant, a tool
manufacturer, and several POTWs.  Landfills and other hazardous waste
TSDFs did not appear very high on the list.  Relative to other area
sources, dry cleaning also was not very significant.  In contrast, several
facilities which are not currently documented in EIS/PS, such as Freeman
Resins (Burlington), ranked relatively high.

     In comparing the results of S1 (the first screening parameters) versus
the results of S2 (the second screening parameter), several observations
could be made.  (As indicated above, S2 takes into account the local ex-
posed population, and the release height of the emissions.) As expected,
sources without tall stacks became more important.  The most important
"source" in this ranking was mobile sources in Polk County, undoubtedly
because of the substantial air toxics emissions emitted near ground level
in a populated county.  While arterial highways may present a fairly small
risk one-by-one, the combination of arterials, expressways, and local roads
together can be important.  Other sources with known stack heights tended
to rank lower in the S2 rankings compared to the S1 rankings.  For example,
the ranking of coal-fired power plants such as the George Neal Station
(Salix), Iowa Power and Light (Council Bluffs), and Iowa Southern Utilities
(Ottumwa) dropped substantially because their average stack heights average
well over 200 feet.

     S3, the noncarcinogenic effect parameter, showed a substantially dif-
ferent ranking because the input variables  (especially the pollutants in-
volved) were substantially different than those for S1 and S2.  Among the
highest ranked facilities are two that are identified as 111(d) sources
in Iowa:  Occidental Chemical (Buffalo), and Agrico Chemical (Fort Madison).
The high rankings for these facilities are clearly due to well documented
emissions and a relatively low acceptable daily intake ("A") value.  Even
more than the S1 and S2 rankings, the S3 rankings included facilities
which have not been documented in EIS/PS as criteria pollutant sources.
Notable examples include Sheller Globe (Iowa City), Stone Container Corpo-
ration (Des Moines), and Mid-Central Plastics (West Des Moines).  Other
sources such as Salsbury Laboratories (Charles City) could have been in-
cluded if there were similar sources in Iowa for comparison.  It should
be noted that the S3 ranking includes many  surface coating sources which
did not rank high in the S1 and S2 summaries.  The reason for this
                                    4-2

-------
situation is that surface coating solvents are generally not carcinogens,
as represented by unit risk values developed by USEPA/CAG.  Therefore, if
surface coating sources are well-documented, the potential non-carcinogenic
impact will be relatively large.
ANALYSIS

     To put the results presented in Tables C.1, C.2, and C.3 in proper
perspective, the nature of the screening parameter equations should be
understood.  Emission estimates in many cases are very rough and in some
cases are "surrogate" values, i.e., they are not associated with any data
specific to that plant, but rather are indirect approximations based on
plants in the same industrial category.  The health data used (Tables 2.2
and 2.3) is limited by the data available on carcinogenic potential from
GAG (and a few other sources), and the minimal information developed on
non-carcinogenic effects.  Within the S2 and S3 rankings, relatively few
facilities were identified with specific release heights, thereby overesti-
mating the importance of certain facilities.  Sources with air toxics emis-
sions which were not specifically documented in EIS/PS were assigned a de-
fault release height of 25 feet or less, thereby maximizing their ranking
in Tables C.2 and C.3.  In addition, plume rise was not taken into effect,
which maximizes the ranking of power plants and other sources with release
temperatures above ambient conditions.  Finally, because total county po-
pulations were used in S2 and S3 rankings, sources on the edge of metro-
politan areas may be over-emphasized, while small sources in densely po-
pulated areas (such as dry cleaners) may be underemphasized.

     In reviewing the results, it is important to note that the relative
ranking of facilities were assigned with respect to other sources in Iowa.
This analysis was developed as a means to prioritize future air toxics
program activities in Iowa (particularly emission inventory activities).
A key, unanswered question is the relative risk which the State of Iowa
faces compared to other states.  If Iowa, in fact, is a relatively low
risk state, even some of the facilities which appear relatively high in
the rankings may not be "significant".  Such an assessment would require
a more in-depth analysis.

     Nevertheless, the rankings point out several key trends:

     *  Area sources of air toxics in Iowa are potentially important,
        particularly mobile sources.

     *  There is a sizable group of facilities which could be significant
        air toxics sources in Iowa that are not documented in EIS/PS as
        criteria pollutant sources.

     *  Known, well-documented air toxics sources in Iowa do rank relatively
        high.

To be sure, a prioritization approach such as the one presented here is
biased towards well-documented sources.  For example, Monsanto (Muscatine)
has been studied extensively because it is a source of acrylonitrile, the
first pollutant chosen by USEPA in its pilot program to "refer" certain
                                   4-3

-------
specific toxic air pollutants to the states.  An in-depth inspection and
analysis of the emissions of this plant was performed in 1984, and the
results of that work (USEPA/OAQPS, 1985b) were used in the prioritization
results presented in Tables C.1, C.2 and C.3.  As a result, relative to
other plants in EIS/PS, air toxics emission estimates at Monsanto were
comprehensive.

     Other specific chemical plants may also pose a local risk.  Freeman
Resins (Burlington) appears high in the rankings because it is the same
Standard Industrial Classifiction (SIC) code as Monsanto,  its emission
estimates are "surrogate" emission estimates and as a result shows up as
an acrylonitrile source when in fact it probably is not.  This facility
is therefore a good example of a source for which additional information
is needed, and a specific questionnaire requesting emission-related infor-
mation is probably justified.

     As more information on individual facilities become available, this
assessment could be expanded.  For example, there are no facilities cur-
rently in EIS/PS in SIC code 2834 (pharmaceutical manufacturing).  As a
result, even for large facilities such as Salsbury Laboratories (Charles
City), under the analysis presented here there was no information (except
for employment data) which could be used to estimate emissions.  Such faci-
lities, if they are to be contacted by questionnaire, could be contacted
for both criteria pollutant and air toxics information simultaneously.

     As mentioned above, rankings in the tables presented here are not suf-
ficient by themselves to indicate that individual facilities necessarily
pose a significant risk.  Coal-fired plants, for example, rank relatively
high on S1 and S2 rankings.  However, risks associated with coal combustion
are tied in a large part to chromium emissions due to trace chromium
concentrations in coal (as well as to emissions of PIC's).  Carcinogenesis
of chromium is tied to its chemical state.  Hexavalent chromium has a
known carcinogenic potential, while trivalent chromium does not.  The
emission estimates and subsequent analysis presented here are based on
the conservative assumption that all chromium emitted is hexavalent, an
assumption that clearly produces a high estimate of the potential relative
impact.

     Finally, with respect to the expanded analyses in this study, it has
been determined that with or without PICs, combustion sources (including
mobile sources) are relatively significant.  Risk assessment on these
sources, particularly using local or facility-specific data, would help
to clarify the actual impacts of these souces.  In addition, while the
expanded mobile source calculations were performed for Polk County, it is
reasonable to expect that other urbanized counties in the State would be
ranked high as well if they had been included in the analysis.

                                CHAPTER 5

                     CONCLUSIONS AND RECOMMENDATIONS
     Several observations may be made about the data bases reviewed and
the sources identified.  First, the review of multiple data bases did in
fact identify potential air toxic sources which might not have been iden-
tified in other ways.  In particular, the review of the Directory of Iowa
Manufacturers indicated numerous potential VOC sources which had not been
in Iowa EIS/PS.  This result appears to confirm the appropriateness of
the basic approach taken in the development of this study.  Second, the
data available in many data bases was not necessarily the data needed to
calculate emissions.  While this result in many cases was expected, and
default values for key parameters could be assumed, a more in-depth review
of specific facilities would most likely provide a less conservative as-
sessment of emissions.  Third, as the study proceeded, it became evident
that several potentially important source categories could have been in-
cluded in the study, but had not been.  These categories include chrome
plating (a source of chromium), sterilizers (using ethylene oxide), and
grain fumigation.  Chrome plating is apparently an undocumented source ca-
tegory due to fairly frequent references to plating operations in some of
the State's hazardous waste summaries.  Ethylene oxide has been identified
as a potential problem in other studies, and none of the data bases here
effectively addressed its use as a sterilant.  Similarly, grain fumigation
was never addressed as a subject in this study.  Given Iowa's status as one
of the largest producers of agricultural products in the country, grain fu-
migation should probably be reviewed, particularly if it is determined that
fumigants used in Iowa are potential carcinogens.

     Nevertheless, this screening study provided a comprehensive review of
point, area and mobile sources of air toxics within Iowa and provided a
consistent way of comparing the risks inherent in specific air toxics emis-
sions.  Both traditional and non-traditional sources were included and po-
tential missing sources of criteria pollutants were identified.  Based on
the prioritization scheme, it appears that three major source groupings of
concern for air toxics are mobile sources, coal-fired power plants, and
selected industrial facilities.

     The rankings discussed in Chapter 4 and presented in Appendix C indi-
cate relative risks in Iowa.  While they do not indicate absolute risks
and they do not indicate risks of sources in comparison to sources in
other states, they do provide evidence for prioritizing further activi-
ties towards development of an air toxics program in Iowa.  The following
recommendations address both the gaps in key data which were found and
additional activities focused the priority sources which have already
been identified.

                                    5-1

-------
1.   Expand Efforts to Develop a Statewide VOC Inventory

     Many air toxics also are VOC.  This study indicated many specific
facilities which are likely VOC sources, but which are not documented in
EIS/PS.  Expanding the VOC inventory would not only provide a data base
for assessing air toxics for these facilities, but if an emission inventory
survey is sent out to these facilities, then VOC and air toxics data
could be gathered simultaneously.

2.   Selectively Send Bnission Inventory Questionnaires to "jligh Risk'L
     Squrcejs^

     Sending questionnaires to numerous facilities across the state would
be desirable eventually.  However, given the fact that in-depth risk as-
sessments have not been done on many (if any) facilities in Iowa, it would
be appropriate first to study a few high risk facilities to determine how
extensive a survey is justified.  Accordingly, in-depth emissions data for
several facilities chosen on the basis of the ranking is needed.  It is re-
commended that a thorough emission inventory of the facilities chosen be
performed to establish a foundation for the risk assessment discussed below
(item 4).

3.   Perform a More In-depth Assessment on Selected Nqn-traditional^ Sources^

     The highest ranking POTWs were the Linn and Polk County plants.  As
with most POTWs in Iowa, data for the purpose of evaluating plant-specific
emissions was largely unavailable and most emissions were calculated with
default values as concentrations for key priority pollutants which were
also VOC.  To test this assumption, it would be useful to analyze one
POTW in the state as a test case.  Using a POTW in an urbanized county
with a mix of industry (such as Linn or Polk Counties) would be an appro-
priate candidate.

     Based on the rankings, landfill emissions generally did not appear to
be a problem.  When special waste authorizations were approved, generally
they were focused on materials which did not offer a large potential for
air toxics emissions.  The one possible exception to this observation was
the Black Hawk County landfill where it is known that hazardous waste has
been deposited in past years.  One of the problems that will be encoun-
tered in terms of an emissions assessment of this facility will be the
actual materials deposited.  It is therefore recommended that potential
ways of investigating the landfill be considered.

4.   DeveIqpment a PiLqt Rijsk As ses sment program

     Perhaps the most significant unanswered question in this study was
the level of risks from the sources which ranked high as a result of the
prioritization analysis.  Risk assessments therefore should be performed
to determine whether the sources or source categories identified here in
fact pose a significant risk (when compared to similar sources in other
parts of the country) or if in fact Iowa has a relatively minimal air
toxics problem.
                                    5-2

-------
     To start, a pilot risk assessment program could be based on the emis-
sions developed for high priority sources through the questionnaires iden-
tified above (Item 2).  Results could be compared to similar sources as
documented.in USEPA's National Air Toxics Information Clearing House
(NATICH) or similar sources.  In addition to providing a start to quanti-
tatively assessing the magnitude and nature of air toxics impacts in Iowa,
it would also provide an opportunity to develop potential approaches to be
used in permit reviews in the future.  As the pilot program develops, risks
from mobile sources could also be studied.

5.   Review Selected Source Categories

     As mentioned above, several source categories received little em-
phasis in this study though they could pose potential problems.  It is
therefore recommended that as available resources allow chrome plating,
sterilizing, and grain fumigation be investigated.

         BACKGROUND FOR ASSESSING PUBLICLY OWNED TREATMENT WORKS
                     AND A PRELIMINARY QUESTIONNAIRE
     As discussed in Chapter 2, there are two main types of potential
sources of emissions.  Within a POTW are sludge incinerators and process
sources.  For incinerators, emissions depend on the composition of the
sludge and the design of the incinerator; heavy metals are the main pol-
lutants of concern.  For process sources, volatile organics are the pri-
mary focus, and emissions can be determined by knowing the specific or-
ganic content and flow of the influent, the effluent, and the residual
sludge.  Partitioning of organics through these streams is the key to
emissions assessment of POTW.  A preliminary questionnaire to allow as-
sessment of these sources is provided here; review of this questionnaire
should be done with the help of references as available (e.g., USEPA/OWWM,
1982 and USEPA/OWWM, 1986).

     Section 6 has three pages; each is a continuation of the information
from the page before; fill in as completely as possible, listing all
printing operations and processes.


1.   Company Name, Company Address, Registration Number, Facility Operating
     Schedule, Information for Calendar Year, Person Completing Form, Date.
     List company name, mailing address, registration number, facility
     operating schedule for the source as a whole, the year for which the
     information is given, using the most recent calendar year available,
     name of person completing form, and date.

2.   Printing Process Name, Reference Number.  Identify by name the print-
     ing process operation for which information is being given (rotogra-
     vure, web offset lithography, etc.).  Page 1 of this section should
     contain only information pertinent to the identified printing process.
     The blank page may be copied and completed for cases where more than
     one printing process exists.  A reference number should be assigned
     to each identified printing process which has the potential to emit
     non-criteria pollutants into the air.

3.   Name of Solvent/Ink Used.      -    List each different ink and solvent
     used for each printing operation, including thinners and cleanup sol-
     vents.  Where possible, give identifying names and numbers.

4.   Gallons/Year.  Give in gallons per year the volume of all inks and
     solvents consumed for this particular printing operation in 1984.  If
     volumes are given in pounds per year, indicate this on the questionnaire,

5.   Name and Volume Percent of Non-Criteria substances in Solvent/Ink.
     Identify the name and volume percent of each non-criteria substance
     contained in each ink and solvent,  in the example, Johnson's Black
     Ink #4237 contains 25.55 volume % toluene, and 35.19 volume % Xylene.
     If the units for number 4 (above) are pounds per year,  give name and
     weight percent of each non-criteria substance contained in each ink
     and solvent and indicate this on the questionnaire.

6.   Person Completing Form, Date, Registration Number.  Name of person
     completing form, date and registration number.

7.   Reference Number.  Use the reference numbers from page 1, with appro-
     priate alphabetic characters to identify the correspondence of stacks/
    • vents to each printing process.  In the example, Reference Numbers
     1A, 1B and 1C are assigned to the three stacks associated with the
     rotogravure printing process identified by Reference Number 1  on
     page 1 .

8.   Stack or Exhaust Data.

     a.  Stack Height in feet above ground level,  if there  is no stack
         or vent as such*  estimated height of emission point and state as
         such.  If there are two or more stacks for the same printing

         process, list separately, giving the- data for each, using the
         reference numbers from page 1  with appropriate alphabetic character
         to show they belong to the same unit.

     b.  Stack Inside Exit Diameter in feet.

     c.  Stack Exit Velocity in feet per minute.

     d.  Stack Gas Exit Volume in actual cubic feet
         per minute.

     e.  Stack Gas Temperature of Exit in degrees
         Fahrenhei t.

9.   Air Pollution Control Equipment

     a.  Manufacturer and Model Number.  Nameplate data from
         control equipment

     b.  Type.  Use codes 1* at bottom of page.  If type not listed,
         enter (99) and specify type.

     c.  Collection efficiency.  List the efficiency in percent
         control that the equipment was designed to control.
         Also, list the actual percent control if tests have
         been made to determine the efficiency.

     For control measures which are unconventional, note this as such.

10.  Person Completing Form, Date, Registration Number.  Name of person
     completing form, date and registration number.

11 .  Reference Number.  Use the reference number from page 1 to identify

FACILITY SUMMARIES

-------
      
-------
                S2 =   QUP   (summed for all pollutants)
                        Where:  Q for benzene is 2,000 pounds
                                Q for methylene chloride is 20,000 pounds
                                U for benzene is 15
                                U for methylene chloride is 4.1
                                P for Des Moines (Polk County) is 303,170

                                (h1)2 is (1.2H1.2) = 1.44

     Therefore  S2 =  ((2,000)(15) + (20,000)(4.1))(311,600)
                                          1.44

                    = 2.4 x 1010
     Several observations may be made about these summaries.  First, there
are numerous potential air toxics facilities in Iowa which manufacture
machinery (especially SICs 3523 and 3531).  Many of these facilities can
be expected to have degreasing, but in many instances degreasing is undo-
cumented if indeed it does exist.  Second, there are many miscellaneous
plastics processing and manufacturing plants (SIC-3079), most of which are
not in Iowa's EIS.  Emissions from these plants vary with the processes in-
cluded, and may in fact be quite small. The limited sources in EIS gener-
ally reflect surface coating solvents, and other pollutants such as styrene
(e.g. Cedar Manufacturing in Cedar Rapids) could be emitted as well.

     Concentrations of air toxics sources in Iowa are rather limited ex-
cept for Cedar Rapids, Des Moines, and several cities along, the Mississippi
River (e.g., Clinton/Camanche, Ft. Madison, Muscatine, and Quad Cities).
For example, Clinton appears to have a concentration of plastics processing
plants, while several 111(d) facilities (sulfuric acid and fluorides) are
located in Ft. Madison.  Major surface coating operations are located in
Waterloo, Des Moines, and several other cities.

     Foundries and other metals operations exist throughout Iowa, and es-
pecially seem to be concentrated in Keokuk.  Such operations can be sources
of many trace metals, including manganese.  Based on emission factors of
0.003 Ib Mn per ton of metal charged for cupolas, one of the most signifi-
cant facilities appears to be Griffin Pipe in Council Bluffs.  Alloy Metal
Products and Alcoa, both in Scott County can be expected to be metals
sources as well.

     Coal-fired power plants can also be expected to be the source of trace
metals, including such elements as cadmium, beryllium, arsenic, and chromium.
Two of the most significant within Iowa are the George Neal Station in Salix
and the Ottumwa station of Iowa Southern Utilities.  In both cases, over
2,000,000 tons of coal per year were burned (1984).  The metal emissions
shown in the summaries reflect this fuel use, as do the reported PlCs
emissions.
                                    B-3

-------
     Finally, there appear to be at least three municipal sludge inciner-
ators in Iowa which could be the subject of further investigation.  These
incinerators are located at:

     *  Cedar Rapids Water Pollution Control Facility
     *  Davenport Water Pollution Control Plant
     *  Dubuque Sewage Treatment Plant

All three plants are currently in EIS.  As there may be a large range of
heavy metals in sludge to be incinerated (e.g. an order magnitude for
many metals), no emissions were estimated for these plants.  To evaluate
each of the plants, an assessment of each plant's sludge would have to
be performed first.

     A key to county codes is provided as page B-28.

            EMISSIONS - Neglible amounts of emissions occur as a result of
                        waste handling.  Depending on the uses of the ma-
                        terials listed, other air toxics emissions may also'
                        occur; polyethylene production results primarily
                        in emissions of monomer.
