                                 NOTICE
     The Procedures for Emission Inventory Preparation consists of these
five volumes.

          Volume I   - Emission Inventory Fundamentals
          Volume II  - Point Sources
          Volume III - Area Sources
          Volume IV  - Mobile Sources
          Volume V   - Bibliography

     They are intended to present emission inventory procedures and
techniques applicable in State and local air programs, and for con-
tractors and other selected users.  The object is to provide the best
available and "state of the art" information.  For some areas, however,
the available source information and data either may allow more precise
procedures and more accurate estimation of emissions or may not be amen-
able to the use of these procedures.  Therefore, the user is asked to
share his knowledge and experience by providing comments, successfully
applied alternative methods or other emission inventory information
useful to other users of these volumes.  Please forward comments to the
U.S. Environmental Protection Agency, Air Management Technology Branch,
(MD-14), Research Triangle Park, NC 27711.  Such responses will provide
guidance for revisions and supplements to these volumes.

1.1  INTRODUCTION

     This document is the last of a five volume series dealing with the
preparation of emission inventories.  It presents an extensive listing of
pertinent reference materials which are currently available in the
literature.  These references were assembled to assist state and local air
pollution agency personnel in preparing and maintaining the emission
inventory.  A concise abstract outlining the specific emission inventory
information is provided for each reference cited.

     The other volumes in this Procedures for Emission Inventory Preparation
series are:

     Volume I—Emission Inventory Fundamentals

     Volume II—Point Sources

     Volume III—Area Sources

     Volume IV—Mobile Sources

Each volume examines the rationale and procedures necessary to prepare an
emission inventory and includes examples to assist the user in understanding
specific methods and procedures.

     This volume of the emission inventory preparation series is presented to
give the agency a central resource which lists relevant emission inventory-
related documents.  As with the other volumes in this series, it will be
updated periodically to include the latest reports, articles, and studies on
emission inventory procedures and activities.  Users of this document are
encouraged to suggest additional references for inclusion in the
bibliography.  These suggestions should be forwarded to:

                        Air Management Technology Branch
                     Monitoring  and Data Analysis  Division
                  Office of Air Quality Planning and Standards
                       Research  Triangle Park, NC   27711

1.2  ORGANIZATION

     This volume is divided into two main sections, References and Abstracts.
References are contained in subsections organized around source and pollutant
type, while the abstracts of the references are listed in numerical order.

     Section 2.0,  References,  simply lists  the title and sponsoring agency or
author for each document.   When an EPA report number or paper number has been
assigned to the document,  that number  is also included to facilitate its
                                     1-1

retrieval.   EPA reports can be obtained from EPA regional offices, the EPA
division which funded the project, or from the National Technical Information
Services in Springfield, Virginia.  In attempting to locate any EPA-related
reference,  the regional EPA Office Library should be contacted.

     Each reference included in Section 2.0 is given an alphanumeric index
number.  This number relates the reference to the source and pollutant types
it discusses and will enable the user to concentrate research efforts in
specific areas of concern.  The left-most character of the index number (which
is always a letter) specifies the source type covered by the document.  These
source types with their respective identifying letters are:

     S - All source types

     P - Point sources

     A - Area sources

     M - Mobile sources

When a reference is concerned with all types of sources, it is assigned a
letter "S."  If a specific reference has applicability to two types of sources
(e.g., point and area), it is listed separately under each source type.

     The first digit to the right of the letter specifies the pollutant
discussed in the reference.  This numerical identifier is assigned as follows:

     1 - All except lead (Pb)

     2 - TSP

     3 - S02

     4 - CO

     5 - NOX

     6 - HC

     7 - Pb

In addition, there is an index number (99) assigned to those documents which
cover program management or are more general in nature.  Again, this numbering
convention allows the user to concentrate on those references which may be of
use in the area of concern.

     Finally, following the pollutant indicator are the three right-most
digits which specify the abstract number.  This number is sequentially
assigned to each abstract and identifies the location of each abstract within
Section 3.0.
                                   1-2

          Source code (S,P,A,M)

     Ninety-eight references are listed by source type and pollutant type in
the reference section.  Table 1 presents a matrix, by source type and
pollutant, of the number of references included in this volume.  Because some
references are listed under more than one source type and/or pollutant, the
total of the numbers shown in Table 1 exceeds the total number of references.

     Abstracts in Section 3.0 are arranged in ascending order of the assigned
abstract number, independent of source type and pollutant.  Abstracts are
assigned source/pollutant keys which cross-reference the abstract to locations
in the source/pollutant subsections of Section 2.0.  The alphanumeric system,
as used with the abstracts,  is presented below.
                    Title of Reference

           Abstract No. (ascending order)

                    (Text of abstract)

     The content of each abstract is oriented toward the emission inventory-
related aspects of the reference.  By reading the abstracts, users of this
volume can quickly review the thrust of many references and select those which
are most pertinent.

     Ideally, this bibliography can be used most efficiently in the following
manner:

     Step 1—In the reference section, find all those references pertaining to
     the source type and pollutant type of interest.  Check listings for "all
     sources" (source code "S") and all pollutants (pollutant/category code
     "1"), in addition to those references cited in specific source/pollutant
     areas.

     Step 2—Use the abstract number associated with each reference to locate
     the abstract in Section 3.0.  Read the abstract and decide if the
     reference may be of value in your project.

     Step 3—Request those references which may be of use from your Regional
     EPA Office Library.  If they do not have the specific reference(s), they
     will direct you to the nearest source.

     This bibliography will be updated as additional documents on emission
inventory preparation become available.  A new emission inventory document
will be assigned the appropriate source and pollutant codes and the reference
inserted under the corresponding subsection(s) in Section 2.0.  The document
will then be assigned the next abstract number in sequence and the abstract
added at the end of Section 3.0.  This system can also be expanded to include
new criteria pollutants (pollutant codes 8 through 98) and new source types
(designated with letter codes as appropriate).

     This paper discusses the purpose and associated constraints of emission
     inventories and is not  intended as a technical guide.  Topics include the
     role of emission inventories in air quality management programs,  as
     planning tools, and as  data bases for simulation modeling.  Technical,
     legal, and economic constraints in conducting emission inventories are
     considered as well as agency interaction with the private sector.
     Deficiencies  of inventories are examined and measures of quality
     assurance are suggested.

     This document represents a significant early effort by EPA to establish a
     uniform documented set of procedures for preparing emission inventories.
     Detailed procedures are given for obtaining and codifying information
     about air pollutant emissions from stationary and mobile sources.  The
     NEDS system, which was developed  specifically for use by state and local
     air pollution control agencies,  is described in some detail.  Because of
     the large amount of information that must be collected, it is recommended
     that the data be handled by ADP means.

     A uniform coding system (NEDS) for the data is encouraged in order that
     the information from one region may be compared with that from another.
     Detailed procedures are given concerning the information to be gathered
     from each source, the methods to  be used to gather the information, the
     codes to be used to simplify the  information on standard coding forms,
     the geographical and population information needed about the area of
     interest, the apportionment techniques and emission factors needed, and
     the methods of displaying the data.  The relation of state and local
     emission inventory systems to the EPA National Emission Data System is
     also explained.

     The major emphasis of this volume is on the development of a VOC emission
     inventory that is useful in various facets of an ozone control program.
     The procedures in this document will be generally applicable to
     developing VOC emission inventories for use in  other program areas and
     also to developing inventories of pollutants other than VOC, including
     NOX.

     Various planning considerations are explored, and guidance is offered to
     the agency to help it decide which inventory approach should ultimately
     be pursued, given the resources it has  available.  A generalized
     flowchart is presented which outlines the major activities necessary in
     the basic emission inventory compilation effort.  A description of the
     various ways source and emission data can be collected on individual
     sources for use in the point source inventory is provided, as well as
     descriptions of procedures for making collective activity level and
     emission estimates for those area sources generally too small or too
     numerous to be considered individually  in the point source inventory.
     Such procedures include making field surveys of actual area source
     activity as well as the use of surrogate indicators of area source
     activity such as population and employment.

     Procedures for handling source test data and performing material  balances
     are described.  The basic use of  emission factors is reviewed, including
     cases where adjustments can be made to  reflect  specific source parameters
     and environmental conditions.  Also presented are procedures for  "scaling
     up" the inventory to account for  missing sources as well as for adjusting
     the VOC emissions to exclude nonreactive components.  Finally, seasonal
     adjustment of the inventory is discussed along  with techniques for
     projecting emission totals and for the  presentation of inventory
     information in various ways useful to the agency.  Reporting can  include
     listings of the individual data items contained in the inventory  files as
     well as various kinds of summary  manipulations.

     The appendices contain a glossary of important  terms used in conjunction
     with VOC emission inventories; a  detailed listing of point source process
     emission points;  summary descriptions of the VOC sources for which EPA
     has or will establish control techniques guidelines (CTG); an example of
     a  cover letter and questionnaire  used in mailing surveys for point source
     inventories;  a number of examples of emission inventory documentation;
     and summary descriptions of the NEDS and EIS/P&R inventory systems
     available from EPA for general use.

     Emissions calculations were  performed for the metropolitan St. Louis Air
     Quality Control Region for unregulated sources with a spatial correlation
     to a grid-element system.   EPA methodology was used to determine
     pollutant emissions.  Equipment source categories included motorcycles,
     lawn and garden equipment, construction equipment, industrial equipment,
     farm equipment, and outboard motorboats.

     Procedures for the estimation of the number of sources, emission factors,
     and emissions by grid elements are explained in detail.  Due to the
     limited data available, some assumptions  were made to determine the order
     of magnitude of emissions.

     adjusting emission factors for local climate and surface conditions,
     deriving temporal apportioning factors,  and estimating hourly
     distributions.  Six sources were examined:  unpaved roads, agricultural
     land tillings, wind erosion of agricultural land, construction sites,
     aggregate storage piles, and unpaved airstrips.  Example calculations are
     included, and results presented show county emission totals for each

     The Aeroraetric and Emissions Reporting System (AEROS) was established by
     the Environmental Protection Agency to serve as a management information
     system for EPA's air pollution research and control programs.  As such,
     AEROS is mainly concerned with the collection, processing, and reporting
     of basic air pollution data.  Various supplementary data files are also
     maintained to provide additional information valuable for the preparation
     and analysis of air pollution data.

     In addition to this overview Volume I, there are four additional AEROS
     volumes which describe AEROS operations in more detail.   AEROS Volume II
     is the AEROS User's Manual, which gives instructions for users to input
     data to AEROS, along with detailed systems descriptions.  Volume III, the
     AEROS Summary and Retrieval Manual, is intended for those who want to
     obtain data from AEROS.   Volume III describes AEROS reports and how they
     may be used, and gives instructions for obtaining them.   Volume IV is the
     NADB Internal Operations Manual,  which documents in detail all NADB
     procedures  related to AEROS.  Although Volume IV is intended mainly as a
     guide for NADB personnel,  certain portions may be useful to persons
     interested  in the details of AEROS operations.  Volume V is the AEROS
     Coding Manual.   It contains tables of standard codes required for AEROS
     data input.

     emission inventories.  Volumes II, III, and IV address specific areas of
     the inventory process,  namely the preparation of inventories of point,
     area,  and mobile sources,  respectively; the fifth volume is a
     bibliography of pertinent  publications relating to inventorying
     activities.  Emphasis in this series is placed on a systematic approach
     to identifying emission data requirements and sources; collecting and
     processing the required information; and presenting the data in a format
     consistent with the intended application of the inventory.  Although
     specific procedures for preparing the emission inventory are provided
     whenever possible, available options and the reasons for them are
     identified and discussed.

     Specifically, this volume  is presented as a reference guide for managers
     and planners of state and  local air quality control programs.  In
     conjunction with the other volumes, it serves as a resource for
     management's use in:

          Planning an emission  inventory,

     meet the TSP standards, fugitive dust emissions exceed point source
     emissions in 139, or 92 percent.  In fact,  fugitive emissions are 10
     times greater than point source emissions in 58, or 39 percent, of the
     AQCRs.  In most cases, unpaved roads provide the largest  source of
     particulate emissions  in the AQCRs.  Agricultural tilling and
     construction sources are also very important and in some  cases are the
     largest emitters.

     Control effectiveness  for fugitive sources  is highly variable and depends
     on such things as type of control, characteristics of the source, local
     climatic conditions, and source activity.  Present control technology for
     unpaved roads, agricultural tilling, and construction activity is
     inadequate.

     This report represents the combined efforts of EPA and steel industry
     experts to establish reasonable particulate emission factors with ranges
     for all known stack and fugitive sources within an integrated steel mill.

     An intensified effort was made to update the iron and steel industry
     particulate emission factors presented in AP-42 and to add, for the first
     time, fugitive source emission factors.  The report is divided into three
     major areas.  First, background information related to the processes in
     the iron and steel industry, along with a process flow chart, is
     presented.  Second, all of the particulate source test data are presented

     The Environmental Assessment Data System (EADS) is a group of independent
     computerized data bases which are interlinked to provide common
     accessibility to data produced by a variety of EPA projects.  RTF's
     Environmental Assessment programs are expected to be heavy contributors
     and users.  Accordingly, the EADS has been structured in a manner such
     that EA data can easily be transferred to the input forms.   However, the
     structure is flexible and comprehensive enough so that data from
     virtually any pollutant sampling and analysis protocol could be
     included.  The EADS is  intended to accept data from either energy systems
     or industrial processes.  Often times these data are multimedia in
     nature; that is, the data include fine particles, gaseous,  liquid and
     solid discharge streams, or any combination, emanating from one source.

     Because pollution controls are developed on a media/pollutant basis, EADS
     must be a media-specific data base system.  Thus, the EADS is composed of
     four independent data bases:  the Fine Particle Emissions Information
     System (FPEIS), the Gaseous Emissions Data System (GEDS), the Liquid
     Effluent Data System (LEDS), and the Solid Discharge Data System (SDDS).
     While independent, the  four data bases are very similar in structure and
     are interlinked.  Interlinking is necessary to enable a control strategy
     analyst or an R&D program planner to select the most environmentally
     acceptable control methods on a systems basis.

     The Electric Power Research Institute sponsored a major air pollution
     monitoring and modeling study which included the Eastern United States
     and parts of Southern Canada.  The primary purpose of the Sulfate
     Regional Experiment (SURE) program was to define the physical and
     chemical mechanisms which link emissions of sulfur oxides (SOX), total
     emitted particulates (TEP), nitrogen oxides (NOX), arid hydrocarbons
     (HC) to ambient concentrations of SC>2 and sulfates.  A major goal of
     the SURE program was to develop a useful air quality model to relate
     emissions to ambient sulfur oxide and sulfate levels over distances of
     1,000 km.

     This report describes one phase of the SURE program and consists of the
     development of a detailed emission inventory.  Source parameters such as
     location, stack height, flue gas temperature, etc. were defined for major
     sources, and emission estimates for manmade sources were developed for
     the following pollutants:  SC^; SO^; NO; N02; low, moderate and
     high reactivity hydrocarbons; and total emitted particulates.

     The compilation of accurate hourly SOX emission estimates for utility
     sources during the SURE intensive measurement periods in 1977, 1978 and
     1979 was emphasized.  One of the crucial aspects of the emission
     inventory program was to provide emission data consistent with associated
     measurement and modeling activities.

     An overview of the SURE program is presented in this report.  The
     specific objectives  of the SURE were to:

          Establish a regional air quality data base through measurement of
          several parameters at the  ground and aloft with specified accuracy
          and precision;

          Establish the location  and magnitude of emissions occurring during
          the air quality measurement period with specific accuracy and
          precision;

          Derive a quantitative method for relating emissions from the
          electric power  industry to regional  ambient air quality as measured
          by sulfur dioxide (S02) and particulate sulfate to establish the
          relative importance of  emission density distribution,  meteorology,
          chemical transformations and removal processes to the  regional
          occurrence  of sulfur and nitrogen oxides (SOX and NOX);

     a priority lisiting of fugitive industrial processes for which source
     sampling is needed.  Industrial processes covered in the assessment are
     those which contribute to fugitive particulate emissions.  The criteria

     Emissions of volatile  organic compounds (VOC) are one of the major
     targets of the control  programs being developed by the EPA Office of Air
     Quality Planning and Standards.   Organic solvents are a major part of
     these emissions.  Knowledge  of the end uses of these solvents provides an
     important clue as to the ways in which solvents are emitted to the
     atmosphere.  The objective of this project was to determine total
     domestic solvent consumption and to provide as complete an end use
     breakdown of this consumption as possible.

     Recently published information on production and end uses of individual
     solvents was reviewed  in the initial phase of the project.  When this
     published information  was found to be incomplete, it was supplemented
     through interviews with solvent producers and marketers.  A rapid
     laboratory method for  determination of the approximate solvent content in
     consumer products was  developed to complement the findings of the solvent
     survey.  The method was applied to products from 16 product categories.

     The solvent survey provided  information about major uses for major
     solvents.  The information on those end uses in which solvents are used
     in minor quantities was frequently not available.  This unidentified
     solvent consumption was determined by subtracting the total identified
     consumption from the total quantity of solvent produced.  Adjustments
     were made for the nonsolvent uses in which the compounds are chemically
     modified (e.g., chemical raw materials, fuels, etc.).  The methods used
     for determination of unidentified solvent consumption are described.

     This report presents the results of a  field testing program to develop
     emission factors for fugitive dust entrainment from paved urban roads.
     Substantial evidence has been compiled which indicates that dust
     emissions from city streets are a major cause of nonattainment of
     national air quality standards for total suspended particulates (TSP).
     Therefore,  the quantification of this  source is necessary to the
     development of effective attainment and maintenance strategies.

     Field testing was conducted at representative sites in the Kansas City
     area.  At one location, controlled amounts of pulverized top soil and
     gravel fines were applied to the road  surface.  The basic measurements
     consisted of isokinetic exposure and concentration profiles of airborne
     dust, particle size distributions, dust deposition profiles, surface dust
     loadings, and traffic characteristics.  In addition, conventional
     high-volume samplers were used to determine attenuation of TSP
     concentration with distance from the source.

     Emissions were found to vary directly  with traffic volume and surface
     loading of silt (fines).  The dust emission factor for normally loaded
     urban streets ranges from 1 to 15 g/vehicle-km, depending on land use.

     Emission factors for lead were developed for each source category; they
     are based on source tests, particulate chemical analyses in the
     literature, industry responses, material balances,  and engineering
     judgment.  Because data in the literature are limited, most of the
     emission factors should be regarded as approximations.

     The overall control device collection efficiencies  for lead were assumed
     equivalent to those for collection of nonlead particulates.  This
     assumption has been verified by limited EPA source  tests on fabric
     filters.  For ESPs and wet scrubbers,  some recent information indicates
     differences in the collection efficiency between particulates and lead.
     Lead compounds are probably less efficiently removed by ESPs and wet
     scrubbers whenever lead emissions are concentrated  in the very fine
     particulate sizes.

     This report summarizes, by source category, estimates of emissions in

     promulgated.  These pollutants,  which are called criteria pollutants, are
     particulates, sulfur oxides (SOX),  nitrogen oxides (NOX),
     hydrocarbons (HC),  and carbon monoxide (CO).  National Emissions Reports,
     which are a series  of  annual reports, are compiled from information
     contained in the National Emissions Data System (NEDS) on emission
     sources.  Compilations of emission data are presented for the nation as a
     whole, for individual  states, for intrastate Air Quality Control Regions
     (AQCRs), for respective state portions of interstate AQCRs,  and for
     interstate AQCRs.

     This report represents the best  available indicators of national

043  Methodology for Inventorying Hydrocarbons,  EPA-600/4-76-013, U.S.
     Environmental Protection Agency,  Research Triangle Park, NC, March 1976.

     Source/Pollutant Key:  P 6,  P 99, A 6,  A 99

     A methodology for estimating emissions  of hydrocarbons to the atmosphere
     is described, with emphasis  on emissions from stationary point and area
     sources.   The methodology is an elaboration of the National Emissions
     Data System (NEDS),  and is based  upon,  but  not limited to, an inventory
     of hydrocarbon emissions within the Boston, MA,  Air Quality Control
     Region;  emissions from motor vehicles are not considered, since they are
     subject  to a different methodology.  Sources of  data and procedures to
     obtain data are described.  Data  sources include trade associations,
     census figures, and  wholesale suppliers.  Examples are given of work
     sheets for compiling data, and of questionnaires with instructions for
     completion that can  be sent  to potential emission sources.  Application
     of the methodology to the St. Louis Air Quality  Control Region for
     development of a hydrocarbon emission inventory  for the Regional Air
     Pollution System is  outlined.

     Estimates of the percentages of vehicles operating in the cold start mode
     are made for 60 locations in the Pittsburgh and Providence regions.  Cold
     start percentages are presented for the morning commuter hours, the
     midday period, the evening commuter hours, and the evening and early
     norning off-peak periods.  The percentage was found to be highly
     variable, depending on both location and time period.  The cold mode
     percentages found were different from those assumed in the Federal Test
     Procedure.  An attempt was made to generalize these results, with
     suggested ranges of values presented for various times and locations.

     Research Institute,  Menlo Park,  CA,  June 1977.

     Source/Pollutant Key:  M 1,  M 99

     The computer program for a completely revised version of the APRAC-1A
     diffusion model is presented and discussed.  The new code uses EPA's
     emission calculation methodology from AP-42.  Gridded and link-by-link
     emissions can be output for hydrocarbons, carbon monoxide, or oxides of
     nitrogen.  Diffusion calculations make use of a receptor-oriented
     Gaussian plume model.  Local winds at the receptor can be used; they are
     interpolated from multiple wind  inputs.  Mixing heights can be calculated
     from sounding data or can be input directly.  Two local source models are
     available, one treating pollutant behavior in a street canyon and the
     other treating vehicle and pollutant effects at a signalized
     intersection.  A small program is included lor decoding Federal Highway
     Administration data tapes.

     The evaluation of the  causes  of ambient levels of ozone and oxidants and
     the development  of control strategies are difficult due to the diversity
     of sources and the varying characteristics of organic  compounds.  A basic
     approach in defining some of  the factors involves the  determination of
     the quantity, location,  and sources  of  hydrocarbon emissions.   This paper
     defines  the preliminary considerations  of a hydrocarbon emission
     inventory which  include:  determination of the need for an emission
     inventory, requirements of the inventory, and constraints of the
     inventory preparation.

     To ensure that emission inventories being developed are prepared using
     current emission factors and are  fully documented,  U.S. EPA Region IX
     instituted a program to provide inventory guidance  to state and local
     agencies and to evaluate the completeness of the inventories.  This paper
     presents the problems encountered by the regional office in dealing with
     incomplete inventories and discusses the minimum criteria for documenting
     an inventory.  These criteria include:  reasons the inventory was
     compiled, differences from previous emission inventories, description of
     data sources, documentation of the copies of questionnaires used in
     surveys, and the documentation of emission factors.  Sufficient
     documentation of supportive information should be provided so that a
     third party can determine how emission estimates were derived.  A summary
     of documentation requirements is  included in the text.

     By using  the  data in this paper,  estimates can be made of Volatile
     Organic Compound (VOC)  emissions  from the  use of architectural  coatings
     and associated solvents.   These emissions  contribute significantly to air
     pollution in  California.   In an effort to  reduce these emissions,  the
     staff of  the  California Air  Resources Board (CARB) developed a  model rule
     to regulate  the  solvent content of  architectural coatings.   Essential to
     the development  of the  model rule was a data base.  This data base was
     established  by use of  responses to  questionnaires that were mailed to
     coatings  manufacturers.   These responses provided data on the sales
     volume of coatings and  solvents and the VOC content of these coatings and
     solvents  for  a given year, 1975.  With these data, the CARB staff
     determined the level of VOC  emissions in California for 1975.  In
     addition,  by  dividing  the level of  VOC emissions by the 1975 population
     of California, the CARB staff has devised  a method to estimate  VOC
     emissions when sales data are not known.   Thus,  two methods of  computing
     VOC emissions are given in this document and, for each method,  the effect
     of the model  rule is shown.

     On-Highway Mobile Sources." The program calculates the  emission factors
     based on year,  speed,  ambient  temperature, vehicle type  and  age
     distribution, operating mode,  and the presence of an Inspection and
     Maintenance program.  All these factors can be input directly to
     represent local conditions, or national averages already  built into the

     This report is the result of an engineering study of fugitive emissions
     from iron and steel industries.   The objectives of the investigation
     were:  the identification of fugitive emission sources, a ranking of the
     sources based on relative environmental impact, and recommendations for
     future research.  Fugitive emission factors for iron and steel sources
     were compiled from literature and from industry sources.  Field sampling
     of particulate emissions from material handling operations was performed
     to develop improved emission factors for open fugitive emission sources.
     Devices for emission control are discussed along with evaluations of
     retrofitting proposed systems to existing operations.

     This report presents an evaluation of particulate emission sources in the
     Phoenix, Arizona, area including a detailed methodology to derive the
     base year and project  baseline emission estimates.   Estimates were made
     for three major particulate emission source categories:  conventional
     sources, anthropogenic fugitive dust sources,  and wind blown fugitive
     dust emissions.  Each  major source category was organized to provide a
     review of previous inventories, documentation  of the emission estimation
     procedures, and the base year emission estimates.  Emissions were
     resolved on both a spatial and a seasonal basis.  Growth and activities
     are evaluated to project emissions in the years 1980 and 1985.   Grid maps
     and graphical emission maps are also presented.

     This report investigated exhaust emissions from heavy duty gasoline and
     diesel engines used in farm,  construction, and industrial applications.
     Exhaust emissions from 12 engines were measured, including 8 diesels and
     4 gasoline engines.  Emissions which were measured included hydrocarbons,
     CO, C02, NO, NOX, 02, total aliphatic aldehydes (HCHO),
     formaldehyde (HCHO), and particulates.

     The emission results obtained in this study, as well as  data obtained
     from other sources, were used in conjunction with information on engine
     population and usage to estimate emission factors.  Estimates of emission
     factors were made using emission data developed on as broad a range of
     engines as possible, taking into account that several of the engines
     tested (as well as others on the market) are widely used in more than one
     of the three areas of application treated in this report (farm,
     construction, and industrial).  National impact was estimated separately
     for each of the three engine applications, based on population and usage
     information developed independently for each application.

     Quality assurance comprises three types of procedures:  standard
     operating procedures;  procedures for finding and correcting errors and
     inconsistencies; and procedures  for data quality assessment.  Quality
     assurance for emission inventories focuses more attention on human error
     than on equipment parameters.  This report presents a set of guidelines
     for developing an emission inventory quality assurance program which
     calls for identifying  the inventory components, estimating the potential
     for errors and errors  with greatest impact on inventory results, and
     developing techniques  for the  control and correction of errors.  Sources
     of errors within emission inventory procedures are discussed and control
     techniques are devised to be preventive or corrective measures.

     the changes and development of air pollution agencies' functions.  The
     predictive relationships  for use in the model are derived from empirical
     information provided by selected existing agencies:  seven state agencies
     and two  local agencies within two of the seven states.  These agencies
     were chosen with regard to the characteristics of each agency and its
     jurisdiction in order to  provide a balanced data set.   The model presents

     Area dust emission sources contribute substantially to the atmospheric
     particulate burden in many parts of the country.  The Environmental
     Protection Agency has identified several fugitive source categories for
     inclusion in the National Emissions Data System (NEDS) area source file.
     Among them are the following categories of fugitive dust sources:

          Unpaved roads (dirt and gravel),

          Heavy construction sites (such as road and building construction),

          Agricultural land tilling,  and

          Unpaved airstrips.

     To determine the impact of these sources,  it is necessary to develop a
     national emission inventory of these sources on a county-by-county
     basis.   Calculation of county emission totals for each source category
     requires,  in addition to the basic emission factor, (1)  an appropriate
     measure of the extent of the source type within the county and (2)
     correction factors which adjust  the emission estimates for local climatic
     conditions and properties of the emitting  surface.

     This report presents guidelines  for the identification and evaluation of
     localized violations of carbon monoxide air quality standards (i.e., hot
     spots) in the vicinity  of streets and highways.  These guidelines
     facilitate the rapid and efficient review of carbon monoxide conditions
     associated with existing urban street systems without the need for
     extensive air quality monitoring.  The procedures presented in the
     guidelines employ  traffic and roadway data in two stages of analysis.
     First, a screening procedure is  used  to identify specific locations on
     the highway network that have hot spot potential.  This is followed by a
     verification procedure, which provides a more detailed analysis of
     specific locations (i.e., those  identified by the screening procedure as
     having hot spot potential).   Both the screening and verification
     procedures utilize a series  of nomographs along with the various traffic
     and street data to assess hot spot potential.  The two procedures are

     This study was performed to develop a methodology which documents the
     bases and criteria for  determining line sources in a metropolitan area,
     and the sensitivity to  monitoring frequency.   The study of automotive
     emissions requires the  efficient monitoring of traffic flow, identifying
     location parameters critical to emissions,  and adequate knowledge of
     vehicular emissions under a range of operating conditions.  The report
     describes the methodology used for documenting the most recent traffic
     data; estimating emission levels; computing aggregate emissions and
     concentrations of CO,  NOX, and HC; conducting sensitivity analyses; and
     verifying the methodology in the St. Louis  AQCR.

     As part of EPA's petroleum refinery assessment  program,  this report
     discusses fugitive hydrocarbon emissions which  were measured from a
     number of types of sources in refineries.   Data was obtained from nine
     refineries throughout the United States.  Sources measured for
     hydrocarbon emissions included valves, flanges, pump seals, compressor
     seals, relief valves, and process drains.   Emission factors for
     nonmethane hydrocarbon emissions from these sources were developed.  In
     addition, a source "screening" procedure was developed and nomographs
     were prepared which relate the maximum screening value to the percentage
     of sources leaking and to the percentage of total emissions represented
     by these leaking sources.

     This report documents  the methodology used to develop the lead emission
     factor for reentrained dust.  Samples of airborne particulate from two
     paved roadways were analyzed for lead content.  The results of these
     analyses were used to  derive the combined particulate lead emission
     factor for vehicle exhaust and reentrained dust.  A separate calculation
     procedure was used to  divide the combined particulate emission factor
     into the emission factors for vehicle exhaust and for reentrained dust.

     This report discusses  the methodology and results of a test program
     conducted to develop emission factors for particulates, carbon monoxide,
     and hydrocarbons from the burning of street tree leaves.  Leaf samples
     from 15 species were burned under controlled conditions to obtain the
     emission factors for each tree species.  In addition,  the moisture
     content of the leaves  was maintained at two distinct levels, 10 and 20
     percent (dry weight basis), to ascertain the affect of this variable on
     emission rates.  Raising the leaf moisture level generally increased the
     production of all three pollutants,  although in varying amounts.

     This report presents the results of an extensive field testing program
     which was conducted to determine emission factors for four categories of
     fugitive dust sources:

          Unpaved roads and airstrips,

          Agricultural tilling,

          Construction sites, and

          Aggregate storage piles.

     The testing was necessitated by the lack of reliable data on the
     characteristics of these sources.  For each source type, the observed
     relationship between emission rate and source activity was used to derive
     a basic emission factor.  In addition, test data were analyzed to
     determine the dependence of the emission rate on properties of the
     emitting surfaces and characteristics of the vehicle or implement which
     caused the emissions.
