ABSTRACT
The U. S. Environmental Protection Agency (EPA) has several ongoing activities in which volatile
organic compound (VOC) and paniculate matter (PM) speciation profiles from a large number of source
categories are utilized. These activities include the preparation of air toxics emission inventories,
receptor modeling, acid precipitation studies, and ozone attainment strategy development.
Over the past ten years, several projects have been conducted that have lead to the
development of the current VOC/PM Air Emissions Species Manual. In 1980, EPA published the "Volatile
Organic Compound (VOC) Species Data Manual, Second Edition* (EPA-450/4-80-015) which provided
VOC species profiles for some emission source categories. In 1985, EPA published the "Receptor Model
Source Composition Library" (EPA-450/4-85/002) which contained paniculate matter (PM) species
profiles for several source categories. More recently, EPA published the "Air Emission Species Manual -
Volume I, Volatile Organic Compound (VOC) Species Profiles" (EPA-450/2-88-003a) and the "Air
Emissions Species Manual • Volume II, Paniculate Matter Species Profiles" (EPA-450/2-88-003b). These
documents represent expansions of the 1980 and 1985 VOC and PM species profile documents.
In 1989 EPA updated the VOC and PM profile data bases by adding in new profiles and making
necessary revisions to existing profiles. These updates are contained in the document "Addendum to
the Air Emissions Species Manual" (EPA-450/2-88-003c). The current system has over 600 chemical
speciation profiles for various stationary point and area and mobile source categories. The contents of
the current system are contained in the reports:
Air Emissions Species Manual - Volume I, Volatile Organic Compounds Species Profiles
Second Edition (EPA-450/2-90-001a). and
Air Emissions Species Manual - Volume II, Paniculate Matter Species Profiles Second
Edition (EPA-450/2-90-001b).
To date, the system has been distributed by EPA in both a computer data base form and in a
hard copy report form. The number of profiles in the system has grown to the point where the
production of a hard copy report of the data base is a very cumbersome and time-consuming task. The
report itself Is nearly 1500 pages in length. In order to streamline the distribution of the system and
make future updates easier, EPA has decided to begin making the system available only in a
computerized data base format that can be distributed on PC diskettes. Hard copy reports of the
hundreds of profiles will not be generated or distributed by EPA.
The objectives of this document are to provide a complete description of the contents and use
of the diskette-only version of the Air Emissions Species Manual, hereafter known as the VOC/PM
Speciation Data System (SOS), and to serve as the overall system User's Guide. The type, number, and
intended uses of the VOC/PM speciation profiles contained in the system are summarized and thorough,
step-by-step specifications are given of the processes needed to install, access, and use the PC diskette-
based system.

EXECUTIVE SUMMARY
The U. S. Environmental Protection Agency (EPA) has several activities that require speciated
paniculate matter (PM) or volatile organic compound (VOC) profiles from several source categories.
Some of these activities are preparation of air toxics and acid precipitation emission inventories, acid
precipitation modeling studies, receptor modeling, and ozone attainment strategy development. In an
effort to update the available speciated PM profile data base, EPA conducted studies to update the
"Receptor Model Source Composition Library" (EPA-450/4-85-002) and produced a revision entitled "Air
Emissions Species Manual - Volume II, Particulate Matter Species Profiles" (EPA-450/2-88-Q03b).
Similarly for VOC emissions, EPA has performed studies to revise the "Volatile Organic Compound
Species Data Manual - Second Edition" (EPA-450/4-80-015) and provide and updated version in the "Air
Emissions Species Manual - Volume I, Volatile Organic Compound Species Profiles" (EPA-450/2-88-
003a). The Air Emissions Species Manual (Volume I and II) was recently updated by the document
"Addendum to the Air Emissions Species Manual" (EPA-450/2-88-003c). The update took the form of
adding in new PM and VOC profiles to the speciation data base and making revisions to several existing
VOC profiles.
More recently in early 1990, EPA produced a second edition of the complete Air Emissions
Species Manual. This second edition was developed by combining the previous complete Manual (EPA-
450/2-88-003a,b) with the "Addendum" document (EPA-450/2-88-003c). The complete second edition
VOC and PM Manual has the EPA number EPA-450/2-90-001a.b.
The second edition Species Manual contains over 550 total profiles (VOC and PM combined). A
wide variety of industrial and non-industrial (e.g., road dust, natural sources) source categories are
addressed by the profiles. There are approximately 300 PM profiles in the Manual and accompanying
data base representing 20 overall source categories. Each PM profile in the system contains the
following information.
• Profile name
• Profile number
• Profile data quality
• Control device identification
• Reference(s)
• Data source
• Source Classification Code (SCC)
-0-051
-------
• Mass fraction data
• Species identification: species identified by Chemical Abstract System (CAS) number,
species number, and species name
• Composition data in weight percent for four size ranges: 0-2.5 urn, 2.5-10 urn, 0-10 urn,
and total paniculate measured
• Uncertainty associated with composition data for four size ranges: 0-2.5 um, 2.5-10 urn,
0-10 um, and total paniculate measured
• Date
Currently, there are about 250 VOC profiles contained in the Species Manual and data base
system. These profiles span approximately 30 industrial and non-industrial source categories. Each
VOC profile contains the following information.
• Profile name
• Profile number
• Profile data quality
• Control device identification
• Reference(s)
• Data source
• Source Classification Code (SCC)
• Chemical species identified by: Storage and Retrieval of Aerometric Data (SAROAD)
code, Chemical Abstract System (CAS) number, species name, molecular weight, weight
percent
• Date
In addition to the VOC/PM profiles based on some level of test data, this data base also
contains VOC/PM profile assignments for all SCC's in the National Emissions Data System (NEDS) and
applicable NEDS area source codes and additional area source codes used in the National Acid
Precipitation Assessment Program (NAPAP). Ideally, a profile would be needed to represent each one of
these categories. However, the number of categories to be characterized is much larger than the
available profiles. Therefore, profile assignments that involve linking a VOC profile to a source category
that does not have an original profile assignment have been developed using sound engineering
judgement.
Source category profile assignments are especially important in activities such as preparation of
air toxics and acid precipitation emission inventories and acid precipitation modeling studies. For
several SCC's, profile assignments using engineering judgement were not possible; however, in such
cases, industry-specific average profiles were developed. These profiles were developed from original
cao.051
ix
-------
profiles representing other SCO's within the same industry group. The industry-specific average profiles
are Intended for use only if there is no other information available. In addition, 'zero' profiles, which is
an overall average based on all the VOC and PM profiles in the data base, was developed. These
profiles are intended for use only as default profiles, to represent those SCO's characterized by "zero" or
"negligible" VOC and PM emission factors.
After producing the second edition of the Air Emissions Species Manual, it became clear to EPA
that it would be impractical to continue publishing a hard copy version of the speciation profiles data
base. The total number of profiles has become very large and will only get larger. Producing and
distributing the hard copy report version is very time consuming and expensive. The nearly 1500 page
document is also extremely cumbersome to use. For these reasons, EPA has decided to only distribute
the system in the future in an electronic form that is personal computer (PC) based. The speciation data
base will continue to be expanded and sent to users, but only on PC diskettes. The system will be
known as the VOC/PM Speciation Data System (SOS).
This document is designed to introduce the new diskette-only version of the data base and serve
as the user's guide for the system. This user's guide describes what chemical speciation profiles are,
what the data base contains, what pollutants and sources are covered, how profiles can be applied, and
how to install and operate the computerized data base system. Under the new system, all users will
need Is a copy of the SDS diskettes and this manual in order to fully use all of the profiles previously
published in the old hard copy reports of the Air Emissions Species Manual. As required, this user's
guide will be revised to incorporate new information or changes in the data system.

SECTION 1.0
INTRODUCTION
The general purpose of this document is to serve as a complete user's guide for the U. S.
Environmental Protection Agency (EPA) informational data base system known as the Volatile Organic
Compound (VOC)/Particulate Matter (PM) Speciation Data System (SDS). The VOC/PM SDS represents
the current computerized version of EPA's Air Emissions Species Manual. The Species Manual has been
transformed Into a completely electronic computerized data base system and all future releases of the
species profiles will be in the form of personal computer (PC) diskettes. This user's guide summarizes
the contents of the data base and clearly instructs the user in how to install and operate the system.
This section of the document provides a general background description of how the VOC/PM speciation
profiles were developed (Section 1.1) and gives an explanation of the organization and use of this
document as the SDS user's guide (Section 1.2).
1.1 BACKGROUND
The U. S. EPA has several ongoing activities that require speciated PM and VOC profiles from
several source categories. Some of these activities include receptor modeling, preparation of acid
precipitation and air toxics emission inventories, acid precipitation modeling studies, and ozone strategy
development.
As part of an effort to update the available speciated VOC and PM profile data bases, EPA has
conducted several studies to update the "Volatile Organic Compound Species Data Manual - Second
Edition" (EPA-450/4-80-015) and the "Receptor Model Source Composition Library" (EPA-450/4-85-002).
These updates produced two new species profile documents entitled "Air Emissions Species Manual -
Volume I, Volatile Organic Compound Species Profiles" (EPA-450/2-88-003a) and "Air Emissions Species
Manual - Volume II, Paniculate Matter Species Profiles' (EPA-450/2-88-003b).
The production of the original Volume I of the Air Emissions Species Manual (EPA-450/2-88-
003a) for VOC was based primarily on the 1980 VOC Data Manual (EPA-450/4-80-015), a field sampling
program, and limited literature data. Revision of the 1980 VOC Data Manual consisted of identifying poor
quality and/or outdated profiles and replacing them with new VOC profiles. Profiles for which there were
no replacements were retained in the data base even if the profiles were of low data quality. In cases
where there were several profiles representing a given source category, the most general profile with the
highest quality level was selected. The profiles extracted from the 1980 VOC Data Manual were included
in the revised manual without any changes except revisions made to data quality indicators for pure
solvent/product profiles. The profiles from the 1980 VOC Data Manual are identified by profile numbers
ranging from 0001 through 0333.
cao.051 * ..
-------
Several new VOC profiles were developed as a result of literature search efforts that focused on
revising the poor quality and/or outdated VOC profiles in the 1980 VOC Data Manual, and filling the
existing data gaps primarily in the air toxics area. The key sources of information used included a study
conducted for the California Air Resources Board source assessment and background information
documents, Section 114 responses and trip reports from several standard development activities, and
work conducted by EPA's Atmospheric Science Research Laboratory. In addition, work performed
during the Northeast Corridor Regional Modeling Project (NECRMP), work conducted under the National
Acid Precipitation Assessment Program (NAPAP), data obtained from Environment Canada, and data
obtained from States were reviewed.
In addition to the profiles developed from existing data, five new VOC profiles were developed
from original data that resulted from a VOC speciation test program (see Appendix G of EPA-450/2-90-
001 a for details). These profiles represent the following source categories: gasoline marketing,
degreasing, drycleaning, autobody repair, and graphic arts-printing.
Recently, the Air Emissions Species Manual was updated by the document 'Addendum to the Air
Emissions Species Manual" (EPA-450/2-88-003c). In the "Addendum" document, 158 new PM profiles,
spanning 14 different source categories, were added to the PM speciation data base, eight new VOC
profiles were added for the oil production source category, and minor revisions were made to three
existing VOC profiles for unleaded gasoline vehicles. The eight additions reflect information on oil wells
and oil field operations that EPA obtained from the Tulsa City-County Health Department. Tulsa recently
conducted a sampling and analysis program to quantify emissions of 30 organic compounds from six
different types of oil field operations. The Tulsa data were submitted to EPA and profiles were developed
according to the protocols and procedures specified in the VOC Air Emissions Species Manual (EPA-
450/2-88-033a). The original Tulsa sampling results can be obtained from the report "Oil Field Emissions
of Volatile Organic Compounds" (EPA-450/2-89-007). The VOC profiles added to the data base by the
Tulsa data are numbered 1205 to 1212.
The revisions to the existing VOC data base involved mobile sources profiles. Minor revisions
were made to the VOC profiles for light-duty gasoline vehicles to reflect corrections necessary for
compounds that coelute on the gas chromatography analyses. The specific VOC profiles affected by the
revisions are 1101, 1203, and 1204. The primary revisions were to the benzene/cyclohexane and
propane/propene splits.
The PM update was performed by contacting researchers working in the areas of PM species
profile development and source receptor modeling. These researchers were questioned regarding the
availability of PM species profile data that were not already contained in the Source Composition Library
or the Air Emissions Species Manual. New species profiles were developed from data submitted by the
researchers for a variety of source categories. The new profiles were developed according to the
protocols and procedures specified in the PM Air Emissions Species Manual (EPA-450/2-88-003b).
cao.051 .. _o
-------
In early 1990. EPA released a second edition of both the VOC and PM portions of the Air
Emissions Species Manual (EPA-450/2-90-001a,b). This second edition was developed by combining
data from the prior edition, EPA-450/2-88-003a,b, with relevant VOC and PM updates contained in the
'Addendum* document. The resulting manual contained over 550 total VOC and PM speciation profiles,
with the split being roughly 300 PM and 250 VOC. The VOC portion of the manual provides profiles for a
wide range of source types spanning 30 industrial and non-industrial source categories. Approximately
20 source categories are represented by the PM profiles. This second edition of the Air Emissions
Species manual was made available to users in both a hard copy report format and on PC diskettes.
In developing both the VOC and PM profiles, several conventions or protocols have' been
followed. One .such convention involved the development of composite profiles. In several instances for
VOC and PM, multiple individual profiles would be available for a given source type or source category.
In these cases, a composite profile would be developed that represented the average or weighted
average of the individual profile data points. Both the individual data and the composite are provided
and the user has the option to apply the specific data if they have the source well characterized or use
the composite if the subject source is a little less well defined.
Second, the activities where VOC/PM species profiles are applied may employ source
classification codes (SCC's) for representing point sources and the National Emissions Data System
(NEDS) area source codes for representing area sources. Ideally, each source category/source code
would be characterized by an appropriate VOC/PM profile. Since there are many fewer species profiles
than source categories, a VOC/PM profile for one category is assigned to other categories that are
judged to be similar to the source category(ies) having an original profile. The speciation data base
contains VOC/PM profile assignments for all SCC's and applicable NEDS area source codes. In
addition, profile assignments are provided for additional area source codes used in the NAPAP efforts.
In cases where there were more than one profile (including a composite profile) characterizing a source
category, profile assignments were based on the composite profile.
For several SCC's profile assignment using engineering judgement was not possible. In such
cases, industry-specific average profiles were developed from original profiles representing other SCC's
within the same industry group. These profiles have numbers starting with 9 and are recommended for
use only if there is no other information available. In addition, Profile 0000 which is an overall average
based on all the profiles in the data base was developed. This profile is intended for use only as a
default profile in applications such as emission inventory development. The "zero" profile is applied to
those SCC's characterized by "zero" or "negligible" VOC emission factors and for which the States or any
other agency have reported nonzero VOC emissions. The SCC's with "zero" and negligible" emission
factors were identified from the document "Criteria Pollutant Emission Factors for the 1985 NAPAP
Emissions Inventory" (EPA-600/7-87-015).1
cao.051 ., n
-------
To provide the reader/user with guidance on the overall quality of data contained in each
VOC/PM profile, an arbitrary scheme (A, B, C, D, E) similar to the one used in AP-422 was used to rank
each profile. For example, Profile Data Quality A was assigned to profiles that were considered
representative of the total population of sources within a given SCO and that were based on sound
analytical techniques with full documentation. Profiles based on engineering judgement and that may
not be considered representative of the total population were assigned Profile Data Quality E. A more
detailed discussion on profile data quality is contained in Section 2.
1.2 SPECIATION DATA SYSTEM AND USER'S GUIDE
The second edition of the Air Emissions Species Manual (EPA-450/2-90-OOla,b) produced in
early 1990 was almost 1500 pages in length. This larger size and the realization that it was only going to
get bigger as new profile data were added to the system, indicated to EPA the need to change the
Species Manual over to a computerized data base only. Continuing to provide hard copy reports of
profile data tables would be both expensive and inefficient. The size of the documents has also gotten
to the point where they are very unwieldy and cumbersome to use. Future releases, therefore, will only
be in an electronic form and hard copy reports of profiles will not be generated or distributed by the
Agency. To this end, this user's guide has been produced.
This user's guide has been assembled to support the release of the species profile data base in
a diskette-only form. The data base will be known as the Speciation Data System (SDS) and will be
available on IBMa-compatible PC diskettes. The diskettes, combined with this guide, should be all a
user needs to successfully implement the system. This user's guide provides a summary description of
how the SDS evolved, how individual VOC/PM profiles are configured and defined, and how profiles can
be applied. These descriptions are given in Section 2.1 for VOC profiles and 2.2 for PM profiles. These
sections also identify the emission source categories covered by the VOC and PM profiles found in the
SDS.
Section 3.0 of this document contains the complete set of instructions needed to install and
operate the SDS. Information is provided on:
• system requirements,
• installation procedures,
• use procedures,
• modify/edit procedures,
• basic system features,
cao.051

-------
• utility features, and
• printing features.
The text is written in a very easy to understand style that provides any level user with a step-by-step
description of all they need to know to obtain maximum benefit from the system. Many example system
data screens are provided to illustrate the text and show the user how they should be progressing.
1.3 SUMMARY OF CHANGES FROM PREVIOUS VERSION
The purpose of this section of the User's Guide is to highlight and summarize changes in the
SDS since the previous version of the system (Version 1.32) was released. Generally, changes may
include modifications to the system programming and features, or additions/deletions of profile data.
«
The most significant change the current data base has over its predecessor are the addition of
several new PM profiles. A total of 43 new PM profiles were added that were obtained from the Pacific
Northwest Source Profile Library.3 These profiles address primarily hogged fuel boilers, lumber products
driers, mobile sources, suspended road and soil dust, wood stoves, and prescribed burning. The Pacific
Northwest profiles represent the results of recent testing of sources in Oregon, Washington, and Idaho
for PM1Q fraction material.

SECTION 2.0
SPECIATION DATA SYSTEM-
SPECIES PROFILE FORMAT AND APPUCATION
The purpose of this section is to provide the Speciation Data System (SDS) user with information
and examples regarding the format of the VOC/PM profiles in the data base, the intended applications of
the profiles, and the limitations of the profiles. The overall set of emission source categories covered by
the profiles are identified. Section 2.1 addresses the VOC portion of the data base and Section 2.2
covers PM.
2.1 VOC SPECIATION DATA SYSTEM
2.1.1 Profile Format
Table 2-1 is an example of the format used to display all VOC profiles. Each of the data fields in
Table 2-1 is defined below.
Profile name: In a majority of the cases, the profile name is the descriptor used for the
applicable source category. In cases where a particular profile is applicable to more than one source
category, a more general term is used to identify a given profile.
Profile number: This is a unique number assigned arbitrarily to a profile.
Profile data quality: A ranking scheme is employed to assign data quality indicators to each
profile. This approach is similar to the one used in the 1980 Data Manual and also consistent with the
approach used in AP-42 for emission factors. The following criteria were used in assigning data quality
indicators:
Data Quality A: Data set based on a composite of several tests using analytical techniques such
as GC/MS and can be considered representative of the total population.
Data Quality B: Data set based on a composite of several tests using analytical techniques such
as GC/MS and can be considered representative of a large percentage of the
total population. Profiles from the VOC field sampling program are assigned
data quality "B."
Data Quality C: Data set based on a small number of tests using analytical techniques such as
GC/MS and can be considered reasonably representative of the total population.

sources (1-01-001-01 through 5-03-900-10) and area sources (01 through 64). Area source codes from
65 through 115 developed under NAPAP are also considered.
Composition data: Each species in the profile data is identified by a SAROAD code, CAS
number, species name, molecular weight, .and weight percentage. SAROAD codes were obtained from
Volume V of the Aeros Manual Series (third edition, September 1986). For species not contained in this
manual, new SAROAD codes have been assigned following the methodology employed in the Aeros
Manual.
In some profiles, the weight percentages are followed by peak identifiers (ID's). The peak ID's
indicate groups of two or three species identified as a single peak in GC and/or GC/MS analysis. In
most cases in this document, one of the species in a given peak was arbitrarily assigned the total weight
percentage corresponding to the peak because of a lack of data to specify a better allocation. For
example, in Profile 1097, peak (1) represents butyraldehyde and crotonaldehyde. The weight percentage
for butyraldehyde is indicated as 1.24, while that for crotonaldehyde is listed as 0.00. A footnote is
included at the end of such profiles to explain peak ID and its use. However, in several of the profiles for
mobile sources, data were available to better allocate coeluting species. In these instances, all of the
cao.051
-------
weight percentage was not arbitrarily assigned to one compound. For example, In Profile 1203, peak
(12) represents benzene and cydohexane. Test data have indicated that the split between the two
compounds should be about 50/50. Therefore, the profile shows the split and not a total allocation to
either benzene or cydohexane.
It should also be noted that in some profiles, a given species appears more than once with
different weight percentages and as part of different peaks. This is primarily due to the inability to
distinguish between isomers of a given species in interpretation of raw GC/MS data. For example, in
Profile 1192, the species isomers of undecane appears three times with different weight percentages:
(1) zero percent, as part of peak (15) shared with octahydroindene (0.04 percent) and C11 olefins (zero
percent); (2) 3.03 percent as a single peak; and (3) zero percent, as part of peak (17) shared with
isomers of butyibenzene (0.10 percent).
Most of the CAS numbers were obtained from the National Air Toxics Information Clearinghouse
Data Base (1985) and the Registry of Toxic Effects of Chemical Substances (1983 supplement to the
1981-82 edition). For some species/group of species, CAS numbers were not identified.
Date: This entry will be used to indicate the date the profile was last reviewed/updated by EPA.
2.1.2 Limitations of Profile Data
All profile data identified through the literature search efforts were used as reported when
developing the new profiles in this study. Only those data sets with sufficient documentation were
included. No attempt was made to verify the completeness/accuracy of the data. The profile data
(i.e., species and weight percentages) extracted from the 1980 VOC Data Manual were incorporated in
the updated VOC data base with no changes.
In some cases, the profiles may not be a full characterization of the emission source. The
individual weight percents of practically all of the VOC profiles sum to 100 percent. This does not,
however, necessarily mean that the compounds shown for any given profile are all that are emitted. The
compounds listed for a profile are those that could be detected with the analytical methods used and /or
were those the particular researcher was interested in at the time of the test(s) used to produce the
profile data. It is very possible that more compounds could have been emitted but they were either not
specifically analyzed for or the analysis technique used were not sensitive enough to detect other
compounds. The VOC profiles have been normalized to 100 percent based on the levels of the
compounds that actually could be detected and quantified and that were the primary focus of the test(s).
Therefore, the user/reader is cautioned to use these profiles with discretion. Nevertheless, the profile
data quality indicator provides a qualitative measure of confidence in a particular profile.

Profiles for individual sources may vary considerably from the values provided in this document.
Therefore, profiles in this document should not be used to characterize specific sources; rather, they
should be used for screening purposes. Source-specific data should always be preferred to the use of
literature data presented in this document.
2.1.3 Profile Applications
There are several ongoing EPA activities that require speciated VOC data as an input parameter.
These activities include preparation of air toxics emission inventories, ozone strategy development, and
preparation of acid precipitation inventories. This section briefly discusses how to use the VOC species
profiles in the preparation of air toxics emission inventories and provides an example calculation.
The easiest way to describe how profiles might be applied is to present a hypothetical example.
A State air pollution control agency is interested in developing an air toxics emission inventory for the
State. An earlier study conducted for the State has identified a list of toxic/potentially toxic compounds
from several emission sources. The emission rates of these individual compounds will be used as an
input to the proposed air toxics regulatory program for the State.
The profiles can identify the relative amounts of individual compounds in a given emission
stream. In most cases, emission factors are available for total VOC's where the compound breakdown is
not specified (e.g., AP-421 or the Criteria Pollutant Emission Factor document2). The information
contained in this data base supplements these general emissions data. For a given source category, the
appropriate VOC species profile should be Identified using the profile name index in the Speciation Data
System. The System can be searched on source category name and all profiles containing that name or
some part of it can be called up. The total VOC emission factor should be multiplied by the weight
fractions for each compound in the profile to determine compound-specific emission factors.
In this example, formaldehyde is one of the toxic compounds on the State's list and airport
operations are a major emission source. Potentially relevant profiles are identified from the System by
searching the file of profile names with terms such as aircraft, airports, etc. Three aircraft profiles are
found. Since the airport in question is commercial, the appropriate profile is Profile 1098: Aircraft
Landing/Takeoff (LTO)-Commercial.
The weight percentage of formaldehyde in Profile 1098 is 15.00. Applying the weight fraction of
formaldehyde to the total VOC emissions for the airport of 500,000 Ib/yr, formaldehyde emissions are
estimated as 500,000 x 0.15 = 75,000 Ib/yr. The user should review the "Data Source" description for
the profile to ensure that the data apply to the specific situation on hand. If there are questions, the user
may wish to review the original document on which the profile is based.

2.1.4 Ust of Source Categories with VOC Profiles
This section contains a listing of the source categories represented by the VOC profiles in the
SDS. Profiles exist for 30 separate source categories. These 30 include the industry-specific average
profiles category and the overall average "zero" profile category. Table 2-2 lists the source categories for
which profiles exist An index of all the individual profiles can be obtained by accessing the SDS.
2.2 PM SPECIATION DATA SYSTEM
2.2.1 Profile Format
Table 2-3 is an example of the format used in presenting the PM profiles in this data base. This
format Is similar to that used in the Receptor Model Source Composition Library except for a few
changes. Composition data and uncertainty information are reported in the Source Composition Library
for size Intervals 0-2.5 um, 2.5-10 urn, and total paniculate measured. In addition to these data, the PM
profiles In the current data base contain composition data for the 0-10 um size interval and uncertainty
information for the 0-10 um interval. The size interval 0-10 um is of particular interest in PM10 source
apportionment studies and in modeling and emission inventory preparation efforts under NAPAP.
Therefore, composition data for this size range are also included in this data base.
Another data item that is included in the profiles is particle size distribution data (i.e., fraction of
mass in a given size interval). The particle size distribution data can be used in estimating size-specific
particulate emission rates in preparation of emission inventories. When combined with the composition
data from the profiles, these data can be used to estimate size-specific and speciated particulate
emission rates. In this data base, size distribution data are coupled with the source profiles from the
Source Composition Library to develop composition data for the 0-10 um size interval.
The profile ratings used in the Source Composition Library were adopted as data quality
indicators. These ratings, however, were modified to take into account the uncertainties associated with
mass fraction data, calculation^ procedures used for the 0-10 um size interval, and also assumptions
used in filling data gaps. As shown in Table 2-3, a dual data quality indicator is used for the profiles
from the Source Composition Library. The first quality indicator is the rating as it appears in the
Source Composition Library, followed by the modified quality indicator. The presence of a single data
quality indicator indicates the profile was developed during studies after the original Source Composition
Library. Each of the entries in Table 2-3 is described below:
Profile Name: The profile name is the descriptor used for the applicable source category.

Profile Number This is a unique number assigned to each profile. Profiles are coded into four
groups as follows: combustion sources (10000 series), industrial processes (20000 series), mobile
sources (30000 series), and area sources (40000 series). Composite profiles developed from individual
profiles are assigned profile numbers in the same series. For example, the profile Unpaved Roads -
Composite Is developed from Profiles 41201, 41203. and 41204 and assigned the number 41220. The
industry-specific average profiles developed from available profiles to characterize source categories for
which no data are available are assigned profile numbers beginning with 9. There are 16 such profiles
(90001 through 90016). Profile 00000 Is an overall average of the profiles in the data base. It is intended
for use as a default profile in applications where nonzero emissions are reported for those SCC's
designated as having zero or negligible emission factors in the Criteria Pollutant Emission Factor
Document2
Profile Data Quality: Dual data quality indicators are used in the profiles contained in this data
base (e.g., C/D). The first quality indicator is the profile rating as reported in the Source Composition
Library. The second quality indicator is the modified rating assigned in this data base. For a profile
obtained from the Source Composition Library, the rating was modified to include the data quality
associated with size distribution data and any assumptions associated with developing the composition
data for the 0-10 um size interval and filling data gaps. The guidelines used in assigning data quality
indicators were somewhat subjective. For those profiles that were not extracted from the Source
Composition Library, a single data quality indicator is included.
It was assumed that the procedures for calculating composition data for the 0-10 um size interval
using mass fraction data would lower the overall profile data quality by one level. Additional
assumptions about missing data (e.g., no data reported for the 0-2.5 um size interval) would also lower
the data quality by one or two levels. For example, Profile 29301 (Primary Lead Smelting - Slag Pouring)
has a profile rating of "C* In the Source Composition Library. The mass fraction data for this profile has
a data quality indicator of "E." For this profile, composition data for the 0-2.5 um and 2.5-10 um size
intervals were not reported. To fill these two data gaps, it was assumed that the composition data for
these two intervals are the same as the one for the total paniculate measured. Thus, the data quality
assigned to Profile 29301 in this document was modified as "E." Specifically, each data quality indicator
represents the following:
Data Quality A: Composition and mass fraction data obtained for the size intervals 0-2.5 um,
2.5-10 um, and total paniculate measured from several sources using sound
sampling and analytical methodology. Profiles are considered representative
and recommended for use.
cao.051 2_10
-------
Data Quality B: Composition and mass fraction data obtained for the size intervals 0-2.5 um,
2.5-10 um, and total paniculate measured from a few sources using a generally
sound methodology.
Data Quality C: Composition data obtained for the size intervals 0-2.5 um, 2.5-10 um, and total
paniculate measured from a few sources using a generally sound methodology
and mass fraction data of below average quality; or composition data obtained
for two of the three size intervals 0-2.5 um, 2.5-10 um, and total participate
measured from a large number of sources using a sound methodology coupled
with mass fraction data of below average quality.
Data Quality D: Composition data obtained for size intervals 0-2.5 um, 2.5-10 um, and total
paniculate measured obtained from a limited number of sources using uncertain
or undocumented methodology coupled with mass fraction data of average or
below average quality; or composition data obtained for two of the three size
intervals 0-2.5 um, 2.5-10 um, and total particulate measured from a few
sources using a generally sound methodology coupled with mass fraction data
of poor quality.
Data Quality E: Composition data obtained for the size intervals 0-2.5 um, 2.5-10 um, and total
particulate measured from a single source using poorly documented
methodology coupled with mass fraction data of poor quality; or composition
data obtained for two of the three size intervals 0-2.5 um, 2.5-10 um, and total
particulate measured from a limited number of sources using poorly
documented methodology coupled with mass fraction data of poor quality; or
composition data obtained for one of the three size intervals 0-2.5 um, 2.5-
10 um, and total particulate measured coupled with mass fraction data of poor
quality; or industry-specific average profiles; profiles with "E" rating are
recommended for use only if there is no other information available.
Control Device: This entry is used to indicate if the profile data represent an emission stream
downstream or upstream of a control device (if present). The downstream composition and size
distribution of particulate emissions would be affected by the presence of a control device.
Referencefe): This entry identifies the primary reference(s) used in development of the profiles.
The reference list is the same as that contained in the Source Composition Library except for additional
references used in developing the new profiles. If more detailed information is required about the data
contained in the profile, the user/reader should consult these reference(s).
cao.051
-------
Data Source: This entry briefly describes the basis of the composition data used in the profile
(e.g., number of tests, sources and samples, sampling and analytical methods, how data were
composited, etc.). More detailed information about the data used can be obtained from the references
indicated in the profile.
SCC: This entry is the code for the source category for which the profile was originally
developed. These codes are obtained from NEDS for point sources (1-01- 001-01 through 5-03-900-10)
and area sources (01 through 64). Area source codes from 65 through 115 developed under NAPAP are
also considered.
Mass Fraction Data: Size distribution data (i.e., the fraction of mass [paniculate emissions]
contained within a specific size range) are reported in this entry. Three size ranges are considered: 0-
2.5 um, 0-6 um, and 0-10 um. Mass fraction data for 0-2.5 um and 0-10 um size ranges are used to
estimate composition data for the 0-10 um size range. Mass fraction data for the 0-6 um interval are
presented as additional information. A large proportion of the mass fraction data was obtained from AP-
42.1
One area of concern is that the mass distribution data and the source profiles used to estimate
composition of the 0-10 um size range are not from the same data set and represent data collected from
different emission sources. This introduces an additional source of uncertainty in the calculations of
composition data for the 0-10 um size interval.
Species Identification: Each species in the profile data is identified by a species number,
species name, and CAS number. In general, the species number is the atomic number for the element.
Other species are arbitrarily assigned the numbers starting with 200 (e.g., total carbon - 200; organic
carbon - 201; elemental carbon - 202; sulfate ion - 203, etc.). The CAS numbers for the species were
obtained from the Registry of Toxic Effects of Chemical Substances (1983 Supplement to the 1981-82
edition).
The species listed in Table 2-3 are those that are most commonly reported in the literature. As
indicated in the Source Composition Library, for those profiles that include other key species, any
standard component may be deleted to permit inclusion of a nonstandard component. Therefore, some
variability exists in the profile format with respect to the list of species considered.
Composition Data: In a typical profile, composition data expressed as weight percent are
presented for four size ranges: 0-2.5 um, 2.5-10 um, 0-10 um, and total paniculate measured. Values
for the 0-2.5 um, 2.5-10 um, and total paniculate measured are based on actual data and are extracted
directly from the Source Composition Library, where available. Values for the 0-10 um size interval are
derived from calculations based on the methodology described in the Source Composition Library.
cao.051 2_1 p
-------
In some cases, profile data were not complete, i.e., data were only reported for one or two size
intervals. In these cases, engineering judgement was used to fill the data gaps. For example, in
Profile 17106 (Municipal Incinerator - Composite), composition data are reported only for the total
paniculate measured as indicated by footnote (1) for the last column in the profile. In absence of other
information, it was assumed that the composition data for the 0-2.5 um and 2.5-10 um size intervals were
the same as that for the total paniculate measured. This assumption is indicated by footnote (3) for
these two size intervals. The following symbols are used in the composition data: NA (not analyzed),
NE (not estimated), and < (below the detection limit). The NE symbol is used in cases where a specific
calculation could not be carried out due to missing data (e.g., NA, <).
Following the data tabulation, the percent of mass accounted for by the composition data under
each size interval is presented. This value is based on the summation of weight percentages of the
species in a given column. The sum does not include oxygen, hydrogen, nitrogen, water, or other
components that were not included in the analysis. In some profiles, the summation of weight
percentages may be greater than 100 due to double counting (e.g., sulfur/sulfate, total carbon/elemental
carbon/organic carbon, etc.). Failure to include the carbonaceous, oxygen, and hydrogen components
in the aerosol characterization is often the largest source of unexplained mass.
Since the composition data in weight percentages are associated with a specific size interval, it
is not possible to add the percentages for a particular species across size intervals. For example, in
Table 2-3, the percentages for Al In the 0-2.5 um, 2.5-10 um, and 0-10 um size intervals are 0.819, 5.827,
and 2.400; and 0.819 + 5.827 ^ 2.400.
Uncertainty: The uncertainty associated with composition data for the size ranges 0-2.5 um, 2.5-
10 um, and the total paniculate measured are based on either the estimated analytical precision of the
measurement (single sample) or the standard deviation of the data sets. The uncertainty associated with
the 0-10 um size range is calculated according to the procedure outlined in the Source Composition
Library. As Table 2-3 shows, the footnotes for the uncertainty columns indicate whether they are based
on data (i.e., extracted from the Source Composition Library) or calculated. In many cases, uncertainties
were either not reported or not known by the authors. The abbreviations used for uncertainty values
include NR (not reported) and NE.
Date: This entry will be used to indicate the date the profile was last reviewed/updated by EPA.
2.2.2 Limitations of Profile Data
As indicated in the Source Composition Library and in the first edition of the Air Emissions
Species Manual, the user should be aware of the limitations of each data set, specifically with
cao.051
-------
respect to measurements of carbonaceous emissions and volatile elements (e.g., Pb, As, Hg, etc.) that
partially exist In the gaseous phase at high stack temperatures. Unless special precautions such as
dilution source sampling, aircraft or balloon methods are exercised, these components will not be
accurately represented in the data. In addition, many of the studies from the literature do not report a
sufficiently broad range of paniculate matter components to account for the majority of the mass,
typically due to the specific sampling and analytical protocols employed. Therefore, studies that use
these source profiles (e.g., receptor modeling) may be unable to apportion all of the ambient aerosol
mass accurately. Thus, the user/reader is cautioned to use these profiles with discretion. The profile
data should be carefully reviewed to ensure that they represent the sources being studied reasonably
well.
In estimating composition data for the 0-10 um size interval, size distribution data were
combined with composition data reported for the 0-2.5 um and 2.5-10 um size intervals. The size
distribution data and the composition data from the source profiles represent data collected from
different emission sources. Therefore, this introduces an additional source of uncertainty in calculating
composition data for the 0-10 um size interval.
In several profiles from the Source Composition Library, composition data information for one or
two size intervals were not reported. To increase the usefulness of the profiles, certain assumptions
were employed to fill these data gaps.
- . If data were reported for a single size interval, it was assumed that data for the other two
intervals were the same. Values for the 0-10 um size interval were also assumed to be
the same.
If data for the 0-2.5 um size interval were missing, it was assumed the data for the 2.5-
10 um size interval could be substituted and vice versa. Values for the 0-10 um size
interval were also assumed to be the same.
If data for the total paniculate measured were not reported, assume the estimated data
for the 0-10 um size fraction can be substituted.
Since the chemical composition of paniculate emissions of many sources is a function of particle
size, application of data based on total paniculate measured to paniculate mass in the fine panicle
fraction (0-2.5 um) or coarse panicle fraction (2.5-10 um) may affect the validity of the analysis. Where
such an assumption is made, it Is indicated with a footnote in each profile.
As pointed out in the Source Composition Library, the user/reader should be aware of the
potential variability in the chemical composition of emissions, both within a source group and between
similar sources. Due to limited availability of high-quality, size-resolved profile data sets, an indepth
evaluation of the magnitude of profile variability is not possible. However, comparisons of profiles based
on literature on the total paniculate measured indicate that profile variability is dependent on the
chemical composition of fuels or process materials, volatility, and sampling and analytical procedures.
cao.051

-------
Profiles for individual sources may vary considerably from the values provided in this data base.
Source-specific data from local sources are therefore preferable to the use of literature data and are
recommended, particularly for regulatory applications. Nevertheless, preliminary analyses based on
source profiles In this data base may be adequate to meet a number of objectives. The reader/user
must ultimately assess whether the data in the document are appropriate for use in any particular
application.
2.2.3 Profile Applications
There are several ongoing EPA activities that require speciated PM data as an input parameter.
These activities include preparation of air toxics emission inventories, receptor modeling, preparation of
acid precipitation inventories, and acid precipitation modeling studies. This section briefly discusses how
to use PM species profiles in the preparation of an air toxics emission inventory and provides an
example calculation.
A hypothetical example is used here to describe how profiles might be applied. A State air
pollution control agency is developing an air toxics emission inventory for the State. An earlier study
conducted for the State has identified a list of potentially toxic species from several emission sources.
The emission rates of these individual species will be used as an input to the proposed air toxics
regulatory program for the State. The proposed program advocates regulating paniculate species in the
fine fraction (I.e., <2.5 um).
The PM profiles can identify the relative amounts of individual paniculate species within specified
size intervals in a given emission stream. In most cases, emission factors are available for total
paniculate matter where the elemental breakdown is not specified (e.g., AP-42, Criteria Pollutant
Emission Factor Document). The information contained in this data base supplements the general
emissions data in AP-42 or the Criteria Pollutant Emission Factor Document1'2 For a given source
category, the appropriate PM species profile should be identified using the index of profile names
available In the SDS. The total paniculate emission factor should be multiplied by the weight fractions
for each species in a given size interval as given in the profile to determine size-specific individual
emission factors.
In this example, cadmium is one of the species on a State's list and emissions from a municipal
waste incinerator are of concern. The incinerator bums routine residential and commercial refuse and is
uncontrolled. Potentially relevant profiles are identified from the SDS by searching the profile names file
with the term municipal waste incinerator. Performing this procedure would indicate that there are three
profiles, 17106, 17107, and 17108, for the municipal waste incinerator category. At this point, the user
should review all of the candidate profiles to see which best corresponds to the particular source in
c.o.051
-------
question. A review of the 'Control Device' field shows that there is only one profile specifically for
uncontrolled incinerators. This would be Profile 17108. A review of the "Species' field indicates that
cadmium Is contained in the profile. If there had been more than one profile applicable to this situation,
the user could have consulted the 'Data Source' field for more refined information on which to make a
profile selection, or the original references(s) on which the profiles were based could be consulted. In
cases with multiple potentially applicable profiles, the 'Data Quality" field may also be useful in selecting
the most preferred profile.
In Profile 17108, the weight percentage of cadmium (Cd) under the "0-2.5 um" column is 0.110
and the fraction of mass associated with this size interval is 0.26. Applying the weight fraction of
cadmium to the total paniculate emissions of 1,500,000 Ib/yr for the incinerator, cadmium emissions in
the fine fraction are estimated as 1,500,000 x 0.0011 x 0.26 = 429 Ib/yr. The uncertainty associated with
the cadmium weight percentage is reported as 0.060 percent in the profile. From this information, a
range for cadmium emissions can be specified as follows:
1,500,000 x 0.26 x (0.0011 - 0.0006) = 195 Ib/yr
1.500,000 x 0.26 x (0.0011 + 0.0006) = 663 Ib/yr
Thus, the annual cadmium emissions in the 0-2.5 um size range may be expected to range from 195 to
662 Ib/yr, with a mean of 429 Ib/yr.
2.2.4 Ust of Source Categories with PM Profiles
This section contains a listing of the source categories represented by the PM profiles in the
SDS. Profiles exist for 23 separate source categories. These 23 include industry-specific average
profiles category and the overall average "zero" profile category. Table 2-4 lists the source categories for
which profiles exist. An index of all the individual profiles can be obtained by accessing the SDS.

SECTION 3.0
SPECIATION DATA SYSTEM USER'S GUIDE
3.1 INTRODUCTION
The Volatile Organic Compound (VOC)/Participate Matter (PM) Speciation Data System (SDS) is
an IBM Personal Computer (PC) based data base application designed to allow easy access and
updates to information. This information consists of VOC and PM chemical speciation factors contained
in the Air Emissions Species Manual. EPA-450/2-90-001 (a) and (b), and emission factors from the
National Emissions Data System (NEDS).
The SDS program allows the user to manipulate three types of information: (1) NEDS emission
factors for VOC and PM; (2) VOC and PM speciated profiles, including general information, SCC Code
assignments, and percentage of species contribution; and (3) information associated with each species
found in a profile.
Two versions of the SDS were developed. One is designed to be used internally by the EPA's
central office and the other by regional and state agencies around the country. The central office
version allows a user to modify and add information to the system data base files. It also allows
distribution backups to be made for use by outside agencies. The second version contains a verification
routine that insures data integrity. If a user modifies a data base from outside the SDS program, it will
detect this as an error condition and abort. Both versions allow the user to browse through the data and
output reports to a disk file or the printer.
A glossary of terms consistently used in this section to explain the installation and use of the
SDS is found in Table 3-1.

3.2.3 Installing the System
The instructions provided in this section assist the user in installing the SDS program onto the
PC's fixed disk. It is assumed that the computer has a floppy diskette drive designated as drive A: and a
fixed disk drive designated as drive C:. The system is intended to be operated with all program, data
base, and index files in the same directory of the fixed drive. This directory should be named
"\SPECIATE."
1. Log onto the fixed disk that will house the SDS program
Type: C: < ENTER >
2. Create a new subdirectory to put the system into
Type: MD \SPECIATE < ENTER >
3. Declare the current directory to be the new subdirectory
Type: CD \SPECIATE < ENTER >
cao.051
-------
4. Insert the system diskette in drive A: and copy all files to the current subdirectory
Type: COPY A:*.* C:\SPECIATE
If the preceding instructions have been followed, the packed files have been copied to the fixed
disk in a subdirectory of the root directory named "\SPECIATE." To unpack the system and the data
files and begin using the SOS program, follow the instructions in the next section, Section 3.2.4.
3.2.4 First-time Execution
To Install the system and data files and begin using the DBMS, follow the instructions listed
below.
1. Log to the subdirectory containing the packed files.
Type CD \SPECIATE
2. Unpack the system and data files.
Type UNPACK
3. Begin program execution (i. e. run the program).
Type SPECIATE
When the SOS program is executed for the first time a set of index files will be built on the hard
drive. This will take about five minutes on a standard IBM AT PC. This construction of index files is only
performed once and every subsequent use of the system will not be delayed.
If the computer file (c:\config.sys) is not properly configured, the SDS program will alter it and
re-boot the computer to set the new configuration.
3.3 SYSTEM OVERVIEW
The SDS program is composed of four distinct types of computer display screens and each has
its own scheme of operation. There is a large degree of consistency in the design of these different
screens.
cao.051
-------
At any time the user may press the escape key (labeled Esc) to cancel an Input operation or
return to a previous screen. In general, the user progresses forward through the system with the
< Enter> key and backwards with the key.
3.3.1 Control Menus
The control menus are a branching point in the program where the user decides which of
several indicated actions to take. The menu screens are recognized by their name (i.e.. Main Menu,
Output menu, etc.), and the double-lined rectangle surrounding the menu options. Figure 3-1 shows the
Main Menu as an example. When a menu appears, the highlighted bar is located over the first option on
the screen and a brief description of this option appears at the bottom of the screen. By pressing the
down arrow key, the highlighted bar will move to the second option and its corresponding description
will appear. By pressing the up and down arrow keys the user may highlight any of the displayed menu
options. To select any of the highlighted menu options the user simply presses the < Enter> key.
An alternative method of selecting a menu option is to press the key corresponding to its first
letter. For example, if the menu options were "VOC System" and "PM System,* the user could type "V
to select the former or "P" to select the latter option. There is no need to press the < Enter > key if an
option is selected via this procedure. Once the letter is pressed, the desired option will immediately be
invoked.
To exit the current menu and return to the previously displayed screen, the user should press
the key.
3.3.2 Search Criteria Screens
A second type of display is the search criteria screen. This is where the user specifies the
information to be retrieved by the SDS program. The search system is based on the Query-By-Example
(QBE) methodology. This means that the user specifies a partial or complete value for one of the listed
categories and all pieces of information matching that value from the data base will be retrieved. Figure
3-2 gives an example of a Search Criteria Screen in which the text "Boiler" is used for retrieval by a
partial match.
To enter a search value, the user must use the up and down arrow keys to highlight a search
category (i.e., Species Name), and press < Enter>. A typing area will be displayed to the right of the
search category and the search value should be typed in. When the user presses the < Enter > key, the
data base will be searched and any appropriate information will be displayed.

-------
The flexibility of this method of retrieval allows the user to be as general, or as specific, as
desired. For example, suppose a user wished to view all pollutant species whose name begins with the
letter "A", the user would simply enter an "A" next to the category called "Species name" and all of the
desired species would be collected and displayed in a table for the user to examine or output to the disk
or a printer.
3.3.3 Scrolling Data Display Screens
Another type of display for user data selection is the scrolling data screen. This screen is
displayed when the user specifies a search criteria value that matches more than one piece of
information in the data base. If in the example given in 3.3.2, the user had entered the letter "A" for the
"Species Name" category, a group of pollutant species would be collected and displayed in a scrolling
data screen. The number of species returned may exceed the maximum number that can be displayed
on the screen at one time. The scrolling feature of this screen allows the user to browse
through the multiple pages of the display. Figure 3-3 shows a screen which scrolls through all matches
found from the search criteria given in Figure 3-2.
When the scrolling data screen appears, a highlighted bar will be on the first line of matching
information. To move the highjighted bar down one item, the user would press the down arrow key.
Repeated presses on the down arrow key will move the highlighted bar to the bottom of the screen and
once there, the screen will scroll up to display previously hidden information. The up arrow key can be
used to move the highlighted bar back up the screen. In addition to the up and down arrow keys, the
user also may use the , , , and keys to manipulate the highlighted
bar. The key will move the entire display up one complete page; the key will move
the display down one complete page; the key will move the display to the first page
(reestablishing the initial display condition); and the key will move the display to the last page.
To select the highlighted item from a scrolling data screen, the user should press the < Enter>
key. To return to the previous screen without making a selection from the scrolling data screen, the user
should press the key.
3.3.4 Data Entry (Modify) Screens
The last type of screen to be discussed is the data entry screen. A screen of this type is used
any time the SOS program needs information from the user. Rgure 3-4 shows a data entry screen for
VOC species information. The user will be prompted to enter data and press the < Enter > key. If the
user enters partial information in response to a request for specific, detailed information, the system will
display a "pop-up" scrolling data screen for the user to select the particular piece of data required.

3.4 SYSTEM FEATURES
To execute the SDS program, the user has to log onto the subdirectory of the fixed disk where
the system resides and type "SPECIATE" followed by pressing the key. The full Instructions for
system execution are listed below.
1. Log onto the fixed disk where the SOS program resides
Type: C: '
2. Log onto the correct subdirectory
Type: CD \SPECIATE
3. Begin program execution (i.e. run the program)
Type: SPECIATE
The first screen that appears is the title screen (see Figure 3-5). It Identifies the program, the
EPA branch producing the SDS program, and the contractor. The user may press any key to proceed
to the Main Menu.
When the user presses a key from the title screen, the Main Menu will be displayed. The Main
Menu is shown in Figure 3-6. The Main Menu serves as the top level of the program structure. To exit
the program and return to DOS, the user should press the key from the Main Menu. If the
key is pressed from the Main Menu, a verification prompt is displayed. If the user responds with
"Y", the data bases will be closed and control will be returned to DOS. If the user responds with any
other key, the Main Menu will reappear and control will remain within the SDS program.
The user may choose either the VOC or PM speciation data systems from the Main Menu. The
EPA version of the SDS program also allows the user to perform the utility operations necessary for
copying the files onto floppy diskette for external distribution. These utility operations are discussed in
Section 3.5.
If a user of the central office version of the system selects either the VOC or PM speciation
system, a Task Menu is displayed. The Task Menu is shown in Rgure 3-7. The Task Menu has two

The distributed version of the system does not have the option of modifying the data and the
Task Menu will not be displayed on that version. Users of the distributed version of the SOS program
should, therefore, ignore references to the Modify option in this user's guide.
The next menu to appear would be either the Output Menu or Modify Menu depending on the
user selection from the Task menu. A user of the distributed version would go directly from the Main
Menu to the Output Menu because the Modify option is unavailable. Both the Output and Modify Menus
contain the same options. Figure 3-8 shows the Output Menu. The Modify menu is labeled as such to
remind the user that they are in edit mode. The Output and Modify menus have three options for the
type of data to manipulate: (1) Profiles, (2) Emission Factors, and J3) Species Data. These options will
each be discussed in their own section.
3.4.1 Soeciated Profiles
If the user selects the Profile option, the Profile Search Criteria Entry Screen is displayed. This
screen has six categories In which the user may enter search criteria: species name, species number
(SAROAD in the case of VOC, or atomic number in the case of PM), CAS number, Source Category
Classification (SCC) code, SCC description, and profile number. The user may enter a partial or
complete value into any of these six categories and all appropriate information in the data base matching
that value will be returned for the user to choose from.
For instance, if the user wanted to view all SCC codes that had "BOILER" in their name, then
"BOILER" would be entered for the SCC name category. After pressing the < Enter> key, a SCC
Enumeration Screen would be displayed. This is a scrolling data screen containing the SCC codes, their
description, and the profile to which they are assigned. The user may then browse through the scrolling
screen using the up and down arrow keys, the and keys, and the and
keys. If the Output option was selected, the user may print the SCC listing to a disk file or the
printer. To continue and display the desired profile, the user would highlight the SCC code and its
profile and press the < Enter > key. At this point the Profile Menu Screen will be displayed.
Alternately, if the user wanted to know which profiles contained the species "Benzene" then the
letter "B", (or the entire word "BENZENE"), would be entered in the species name category (see Figure 3-
9). After pressing the < Enter> key, all species whose name begins with a "B" would be displayed in the

Species Enumeration Screen (see Figure 3-10). This is also a scrolling data screen and the user may
browse through this screen. If the Output option was selected, the user may print the Species listing to
a disk file or the printer. By highlighting Benzene and pressing the < Enter> key, the Profile
Enumeration Screen will be displayed. The Profile Enumeration Screen is shown in Figure 3-11. This
scrolling data screen lists all profile numbers, their name, and (in descending order) the percent
contribution of benzene they contain. To select a specific profile to view, the user should move the
highlighted bar to the profile and press the key. The screen shown in Rgure 3-12 will then
appear allowing printer or file output if the Output Option has been selected. Pressing < Enter > to
continue will bring the user to the Profile Menu Screen.
The Profile Menu Screen contains the profile name, profile number, and profile data quality at the
top of the display and the Profile Menu at the bottom. The Profile Menu has either four or five options
depending on whether the VOC or PM system is in use. The VOC system has four options: (1)
Speciation Data, (2) SCC Assignment Data, (3) General Information, and (4) Reference(s) (see Figure 3-
13). The PM system contains these four options plus an additional Mass Fraction and Reactivity option.
If the EPA version of the SDS program is being used and the Modify option has been selected,
the Profile Menu Option to be modified should be highlighted and the < Enter> key pressed. This will
cause a "pop-up" Edit menu to be displayed. The Edit menu gives a user the option of changing the
data, deleting the data, or adding new data. By selecting the Change option, the current information is
displayed and the user may type over this data to change it. If the Delete option is selected, the user is
asked to verify the deletion. Upon verification, the information will be deleted from the data base. If the
Add Data option is selected, the user is asked to verify this addition and a blank entry screen is
displayed for the user to enter the new data. When a new profile is added, the general information must
be entered first.
The user may view the profile speciation information by selecting the Speciation Data option.
The screen shown in Figure 3-14 is then displayed. The speciation information contains a list of the
species, their CAS number, and their percent contribution within the profile. The 0-30 column in the PM
speciated display refers to the Total Paniculate Measured.
By selecting the SCC Assignment option, the user may view both the original and surrogate SCC
assignments (see Figure 3-15). Original assignments refer to those SCC codes directly associated with
the profile and surrogate assignments refer to those SCC codes that for lack of their own profile are
assumed to be fairly represented by the profile they are assigned to.
The general information of a profile may be viewed by selecting the General Information option
(see Figure 3-16). The general information consists of control devices, references, and any notes
concerning the profile's development.

Upon selection of the Reference option the system will display the reference numbers and text
(see Figure 3-17). The bottom of the screen will indicate what options are available to the user. For
example, if there are more references than will fit on the screen, the user will use the option to
view the next page.
If the PM system is in use, the mass fraction and reactivity Information for the profile may be
viewed by selecting the Mass Fraction option.
Once the user has finished examining this particular profile, the key may be pressed to
return to Benzene's Profile Enumeration Screen. It will be noted that this screen is restored to its
previous state and another profile containing benzene may now be selected or the user may press the
key to return to the Species Enumeration Screen. This screen is also restored to its previous
condition and another species beginning with "B* may be selected. Selection of another species would
cause a new profile enumeration screen to be created and displayed. It would contain a list of the
profiles containing that species and their percent contribution. By pressing the key from the
Species Enumeration Screen, the user is returned to the Profile Search Criteria Entry Screen where
another search criteria may be entered. Pressing the key from the Profile Search Criteria Entry
Screen returns the user to the Output or Modify Menu.
3.4.2 NEDS Emission Factors
If the user selects the Emission Factor option, the Emission Factor Search Criteria Entry Screen
will be displayed. Here the user has the option of locating an emission factor by SCC code or by
description. Upon entering data into one of these two categories the SCC Enumeration Screen (see
Figure 3-3) is displayed. This is a scrolling data screen that contains all SCC codes, descriptions, and
emission factors matching the search criteria. If the Output option has been selected, the user may print
this list to a disk file or the printer. By highlighting one of the SCC codes and pressing the
key, a speciated emission factor profile will be generated on the scrolling Speciated Profile
Screen. If there is more than one profile assigned to the SCC code, the user will be given a pop-up
menu to select the one to use.
The Speciated Profile Screen (see Figure 3-18) lists ail species and their emission factors for the
given profile. This report may also be printed to a disk file or the printer if the Output option has been
selected. By pressing the key, the user is returned to the SCC Enumeration Screen where a
different SCC code may be selected. In this event, a new speciated profile will be displayed. By
pressing the key from the SCC Enumeration Screen, the user is returned to the Emission Factor
Search Criteria Entry Screen. If no more criteria are to be entered, the user may press the key
to return to the Output Menu.

3.4.3 Species Information
The final option on the Output menu is the Species Data option. By selecting this option, the
user Is presented with the Species Search Criteria Entry Screen. The user may enter values for three
categories. These categories are: species name, species number (SAROAD in the case of VOC, or
atomic number in the case of PM), and CAS number.
If the user were to locate all species whose CAS number begins with "7", a "7* would be entered
in the CAS number category (see Figure 3-19). After pressing the key, the scrolling Species
Enumeration Screen would be displayed. This screen would list all species whose CAS number begins
with *T. This screen is shown in Rgure 3-20.
If the Output option was previously selected, the user may print the species listing to a disk file
or printer. If the Modify option was selected, the user may highlight the species to be modified and
press the < Enter> key. At this point, a "pop-up" edit menu is displayed. The edit menu gives a user the
option of changing the data, deleting the data, or adding new data. By selecting the Change option, the
current information is displayed and the user may type over this data to change it. If the Delete option is
selected, the user is asked to verify deletion. Upon verification, the species will be deleted from the data
base. If the Add Data option is selected, the user is asked to verify this addition and a blank entry
screen is displayed for the user to enter the new species data.
If the user presses the key from the "pop-up" edit menu the Species Enumeration Screen
is restored. By pressing the key from the Species Enumeration Screen, the user is returned to
the Species Search Criteria Entry Screen, and pressing the key from the Species Search Criteria
Entry Screen returns the user to the Output Menu.
3.5 UTILITY FUNCTIONS
This section is relevant only to users of the EPA central office version of the SDS program. If a
user of the EPA version selects the Utility option from the Main Menu, the Utility Menu will be displayed.
The Utility Menu has three options: Date Stamp, Backup and Print Document. The Utility Menu is
shown in Figure 3-21. In order for backups to be performed and distribution disks to be created, the
data base files must be date stamped. That is, all files must all be given a common date to be specified
by the EPA user. This date will also be encoded on a disk file. If a user tries to perform a backup
operation without having date stamped the data bases first, the backup operation will abort and the user
will be returned to the Utility Menu. The user may press from the Utility Menu to return to the
Main Menu.

16. ABSTRACT
The U. S. Environmental Protection Agency (EPA) has several activities that
require speciated volatile organic compound (VOC) or particulate matter (PM) profiles
from several source categories. To support these activities, EPA has produced the
two volume Air Emissions Species Manual (EPA-450/2-90-001 a & b). Because of the
large size of the Air Emissions Species Manual, over 1500 pages, EPA has decided
to discontinue making it available in hard copy format.
This document contains the documentation and users guide for the data system
that replaces the Air Emissions Species Manual. The document must be accompanied
by the 5 1/4 inch diskett which contains the VOC and PM data bases. In addition
to all of the speciation profiles contained in the Air Emissions Species Manual,
43 new particulate matter profiles have been added to this updated data system.
