1.0 INTRODUCTION
1.1 What is the National Emissions Inventory?
The National Emissions Inventory (NEI) is a comprehensive inventory covering all
criteria air pollutants (CAPs) and hazardous air pollutants (HAPs) for all areas of the United
States. The NEI was created by the EPA's Emission Inventory and Analysis Group (EIAG) in
Research Triangle Park, North Carolina.
This report presents an overview of how the point source component of the final 2002
NEI was compiled. Ultimately, the final 2002 NEI will be used to support air quality modeling
and other activities. To this end, the EPA established a goal to compile comprehensive, facility-
specific data in its 2002 base year NEI for point sources, in addition to preparing nonpoint area
and mobile source 2002 base year inventories.
1.2 Why Did the EPA Create the NEI?
The Clean Air Act (CAA), as amended in 1990, includes many mandates for the EPA
related to CAPs and HAPs. Regulatory agencies rely on emission inventories as indicators of air
quality changes and to set permit requirements. The NEI contains emission estimates for the
following CAPs:
Carbon monoxide (CO)
Condensible particulate matter (PM-CON)
Filterable and primary particulate matter less than 2.5 microns (PM2.5-FIL and
PM2.5-PRI)
Filterable and primary particulate matter less than 10 microns (PM10-FIL and
PM10-PRI)
Nitrogen oxides (NOx)
5
-------
Sulfur dioxide (S02)
Volatile organic compounds (VOC)
Ammonia is also included in the NEI as a precursor to PM formation. Lead is both a CAP and a
HAP.
The NEI is a tool that EPA can use to meet the CAA mandates for HAPs as well. The
CAA presents a list of 188 HAPs (see http://www.epa.gov/ttn/atw/origl89.html for a list of
pollutants and their chemical abstract service [CAS] numbers), for which EPA is to identify their
sources, quantify their emissions by source category, develop regulations for each source
category, and assess public health and environmental impacts after the regulations are put into
effect.
1.3 How Will the EPA Use The NEI?
It is anticipated that the 2002 point source inventory developed from this effort will have
multiple end uses. The data have been formatted according to protocols established for the
EPA's NEI submittals. The common data structure on which the NEI platform is based will
allow the NEI point source data to be transferred to multiple end-users for a variety of purposes.
The CAP emission inventory data are used in State Implementation Plans (SIPs),
compliance demonstrations, emissions trading, and in modeling activities designed to evaluate
ambient air concentrations.
The NEI is a critical component of the EPA's National Air Toxics Program (as described
in EPA's July 19, 1999 Federal Register notice, 64 FR 38706). The initial objective is to make
the data available to EPA modelers for use in the National Air Toxics Assessment (NATA). In
addition, the emissions data compiled as part of this inventory effort will be used in residual risk
assessments conducted by EPA.

1.4 Report Organization
Following this introduction, Section 2 provides the Information Quality Guidelines
Addendum, a summary of the procedures EIAG implements on the NEI, to make the
development of the inventory more transparent. Section 3.0 provides information on how the
2002 NEI point source emission estimates were first derived from state, tribal and local agency
inventories, from data provided by the EPA's Emission Standards Division (ESD), from electric
generating utility (EGU) data collected by the Department of Energy (DOE) (DOE, 2003) and
EPA's Clean Air Markets Division (CAMD) (EPA, 2004a), and from the Toxic Release
Inventory (TRI) (U.S. EPA, 2004b) and how these data sources were combined by EPA into the
draft and final 2002 NEIs. Section 4.0 provides information on how the inventory data were
compiled into a common data structure. Section 5 describes the process for future updates to the
2002 NEI. Section 6 presents references cited in this report.
Appendix A provides summary information on the state, local, and tribal agency
inventory data provided to EPA for use in the draft 2002 NEI. Appendix B lists the source of
facility lists used to flag facilities in each Maximum Achievable Control Technology (MACT)
and Section 112(k) Area Source Standards category in the final 2002 NEI.

ADDENDUM FOR THE 2002 NEI
2.1 Purpose
The National Emissions Inventory (NEI) is a comprehensive inventory covering all
criteria air pollutants (CAPs) and hazardous air pollutants (HAPs) for all areas of the United
States. The NEI was created by the EPA's EIAG in Research Triangle Park, North Carolina.
Ultimately, the 2002 base year NEI will be used to support air quality modeling and other
activities. To this end, the EPA established a goal to compile comprehensive, facility-specific
data in its 2002 base year NEI for point sources, in addition to preparing nonpoint area and
mobile source 2002 base year inventories.
2.2 Explanation of Potential Uses
The Clean Air Act (CAA) includes many mandates for the EPA related to CAPs and
HAPs. The NEI is a tool that EPA can use to meet the CAA mandates. Regulatory agencies
rely on emission inventories as indicators of air quality changes and to set permit requirements.
The CAA presents a list of 188 HAPs for which EPA is to identify their sources, quantify their
emissions by source category, develop regulations for each source category, and assess public
health and environmental impacts after the regulations are put into effect.
It is anticipated that the 2002 point source inventory developed from this effort will have

(SIPs), compliance demonstrations, emissions trading, and in modeling activities designed to
evaluate ambient air concentrations.
The NEI is a critical component of the EPA's National Air Toxics Program. The initial

Assessment (NATA). In addition, the emissions data compiled as part of this inventory effort
will be used in residual risk assessments conducted by EPA.

-------
2.3 Product Content - Inputs, Methodologies, and Outputs
The scope of the inventory effort was to compile 2002 base year emissions data for point
source facilities in the United States, its territories, and tribal areas.
Criteria pollutant emissions for the NEI are collected under the Consolidated Emissions
Reporting Rule (CERR) (40 CFR Part 51). Under the CERR, EPA requires states to report SO2,
VOC, NOx, CO, Pb, PM10, PM2.5 and NH3. The CERR specifies two sets of reporting thresholds
for criteria pollutants. Type A (large sources) must report annually, while Type B sources must
report every three years. The actual thresholds differ by pollutant and depend upon whether the
source is in a nonattainment area or not. For the 2002 NEI, EPA collected information on both
Type A and Type B sources.
For HAPs, major sources are defined in the CAA as stationary sources that:
Have the potential to emit 10 tons per year (tpy) or more of one HAP; or
Have the potential to emit 25 tpy or more of any combination of HAPs.
Smaller point source facilities with annual emissions below these thresholds can be
defined as point area sources and inventoried as such. While states are more likely to report
major sources as point sources and smaller sources as nonpoint sources, there are no reporting
thresholds for the NEI, and EPA encourages states to submit small sources to the point
inventory. In particular, some source categories which are composed of smaller facilities may
emit pollutants which have a high toxicity, and states, local agencies and tribes may give these
categories higher priority in data collection efforts as point sources.
The goal in developing the point source NEI was to obtain facility-specific data such as
facility name, location, stack information, emissions, and process descriptions. It was hoped that
the data would be sufficient to support modeling and risk assessment needs. The starting point
9
-------
for obtaining these facility-specific data was, therefore, state and local air pollution control
agencies and tribes, who are most likely to have this type of detailed inventory data.
State and local agencies and tribes were asked to supply emission inventory data to the
EPA. Inventory data and facility lists were also requested from the EPA's Emission Standards
Division (ESD) for Maximum Achievable Control Technology (MACT) and Section 112(k)
Area Source Standards categories. EIAG also collected emission inventory data for electric
generating units (EGUs) from the Department of Energy's (DOE) Energy Information Agency
(EIA) and EPA's Clean Air Markets Division (CAMD).
To develop a complete point source NEI for HAPs, EPA's Toxic Release Inventory (TRI)
data were also used. The purpose of appending TRI data to the tribal-, local-, state-, and ESD-
combined databases was to make sure all HAPs and ammonia emissions data for facilities that
report to TRI are included in the NEI.
The EIAG report NEI Quality Assurance and Data Augmentation for Point Sources (U. S.
EPA, 2006) provides details on all of the quality assurance (QA) and augmentation of the initial
data obtained for the 2002 NEI. A variety of QA activities are conducted to identify duplicate
records, referential integrity problems, and records with missing or out-of-range parameters that
are needed for air quality and exposure modeling.
EPA also created QC reports which it distributed to states, tribes, and local agencies after
the initial receipt and processing of the data submittals and during its internal review period. It
provided reports on this process to give states, tribes, and local agencies a chance to fix errors,
review augmented data, and provide comments on EPA's process.
NEI output data are released in a number of formats. EPA's file transfer protocol (ftp)
site has separate national point, nonpoint, onroad, and nonroad mobile source 2002 NEI files.
The specific data structure used for the 2002 NEI is based on NEI Input Format (NIF)
10
-------
Version 3.0. The files posted include a README file that describes the different files posted on
the site and how to use them, several summary files that bring together important NEI data
elements in a more compact format, and lookup tables to aid in decoding abbreviations used
throughout the inventory.
2.4 Product Limitations and Caveats
The 2002 NEI is a composite of emission estimates generated by state and local
regulatory agencies, tribes, industry, and EPA. Because the estimates originated from a variety
of sources and estimation methods, as well as for differing purposes, they will in turn vary in
quality, pollutants included, level of detail, and geographic coverage. However, this compilation
of emissions estimates represents the best available information to date.
Users of the data should consider that pollutants emitted from a particular source may
have little impact on the immediate geographic area, the amount of pollutants emitted does
not indicate whether the source is complying with applicable regulations, and risk of individual
HAPs may not correspond to risks associated with emissions of HAPs (e.g., 1 lb of benzene
emissions and 1 lb of toluene emissions do not result in equal risks).
In addition, state, tribal and local agency-supplied emissions data are given priority in the
point source NEI. These submissions are reviewed by the EIAG for data handling and entry
errors, and potential double counting. The estimation methods, reliability of data sources and
calculations, and other quality assurance issues are the responsibility of the preparing agency.
To the extent possible, state, local, and tribal agency-supplied data that appear as outliers in the
data set are flagged for further review, and state/local/tribal agency officials are contacted to
verify the validity of the data. In some cases, the questionable data are removed.
For some source facilities, emission estimates were not available for 2002. In these
cases, data for other base years were used. For some of these source categories, ESD provided
emissions data for a year other than 2002 and noted that the data are the best available to
11
-------
represent 2002. When data are reported for a year other than 2002, the year of the emission
estimate is noted in the NEI. Mercury emissions from electric utilities were not included in the
draft version of the Point Source NEI due to considerations associated with the proposed Clean
Air Mercury Rule (CAMR), but are included in the final version of the point source NEI. EPA
issued the proposed CAMR concerning coal- and oil-fired electric utility steam generating units
(power plants) on January 30, 2004, and issued a supplemental proposal on March 16, 2004. The
proposed rule presents two primary alternative approaches to regulating mercury from power
plants. EPA received numerous comments on its proposed regulatory approaches, and evaluated
those comments to determine how the new data and information received in the comments
affected the benefit-cost analysis and regulatory options under consideration. The final CAMR
as promulgated prior to the release of the final 2002 NEI. Thus, mercury emissions from electric
utilities were only included in the final 2002 NEI.

3.0 DEVELOPMENT OF THE FINAL POINT SOURCE NEI
The scope of the inventory effort was to compile and subsequently update 2002 base year
emissions data for point source facilities in the United States and its territories.
CAP emissions in the NEI are collected under the Consolidated Emissions Reporting
Rule (CERR) (40 CFR Part 51). Under the CERR, EPA requires states to report S02, VOC,
NOx, CO, Pb, PMio, PM2.5 and NH3. The CERR specifies two sets of reporting thresholds for
CAPs. Type A (large sources) must report annually, while Type B sources must report every
three years. The actual thresholds differ by pollutant and depend upon whether the source is in a
nonattainment area or not. For the 2002 NEI, EPA collected information on both Type A and
Type B sources.
For HAPs, major sources are defined in the CAA as stationary sources that:
Have the potential to emit 10 tons per year (tpy) or more of one HAP; or
Have the potential to emit 25 tpy or more of any combination of HAPs.
Smaller point source facilities with annual emissions below these thresholds can be
defined as point area sources and inventoried as such. While states are more likely to report
major sources as point sources and smaller sources as nonpoint sources, there are no reporting
thresholds for the NEI, and EPA encourages states to submit small sources to the point
inventory. In particular, some source categories which are composed of smaller facilities may
emit pollutants which have a high toxicity, and states may give these categories higher priority in
data collection efforts as point sources.
The goal in developing the point source NEI was to obtain facility-specific data such as
facility name, location, stack information, emissions, and process descriptions. It was hoped that
the data would be sufficient to support exposure and other modeling analyses, calculate risk,
project control strategies, and track progress to meet the requirements of the CAA. The starting
13
-------
point for obtaining this facility-specific data was, therefore, state and local air pollution control
agencies, who are most likely to have this type of detailed inventory data.
3.1 EIAG Requested State, Local, and Tribal Inventory Data in 2004 and Revisions in
2005
State and local agencies and tribes were asked to supply CAP and HAP emission
inventory data to the EPA in June 2004. If they were unable to provide emission inventory data,
then the EPA prepared default emission inventory data for the 2002 NEI. EPA will use these
data to support assessments which will be used in regulatory decision making.
The target inventory area includes every state, tribal area, and territory in the United
States and every county within a state. There are no boundary limitations pertaining to
traditional criteria pollutant nonattainment areas or to designated urban areas. If a facility was
included in a state or local database, it is included in the NEI regardless of where in the state it
was located. The pollutants inventoried include all CAPs:
Carbon monoxide (CO)
Condensible particulate matter (PM-CON)
Filterable and primary particulate matter less than 2.5 microns (PM2.5-FIL and
PM2.5-PRI)
Filterable and primary particulate matter less than 10 microns (PM10-FIL and
PM10-PRI)
Nitrogen oxides (NOx)
Sulfur dioxide (S02)
Volatile organic compounds (VOC)
Lead (Lead is also a HAP)
14
-------
The CAP emission inventory data are used in State Implementation Plans (SIPs),
compliance demonstrations, emissions trading, and in modeling activities designed to evaluate
ambient air concentrations, exposure assessments and risk calculations.
The NEI requested data also include ammonia, a PM precursor, and the 188 HAPs
identified in Section 112(b) of the CAA. Some agencies collect information on more toxic air
pollutants, but only the 188 HAPs are included in the NEI. In addition to numerous specific
chemical species and compounds, the list of 188 HAPs includes several compound groups (e.g.,
individual metals and their compounds, polycyclic organic matter (POM), and glycol ethers); the
NEI includes emission estimates for the individual compounds wherever possible. Many of the
uses of the NEI depend upon data for individual compounds within these groups rather than
aggregated data on each group as a whole. The pollutant code table that lists all of the specific
pollutants and compound groups included in the 2002 NEI along with their Chemical Abstract
Services (CAS) numbers (for individual compounds) can be found in the 2002 State Lookup
File, 02nei_lkup_states.zip, found at:
ftp://ftp.epa.gov/EmisInventorv/2002finalnei/documentation/point/ .
Table 3-1 summarizes the data elements that were targeted for the inventory request.
EIAG requested 2002 facility, unit, process, or stack-specific emissions data. If nonpoint area
and mobile source data were available, these were also requested. No limits were set on the type
of source categories for which data would be collected. For CAPs, EIAG expected that at a
minimum states, local agencies and tribes would comply with the CERR reporting requirements
for Type A and Type B sources. For HAPs, it was expected that each agency would have
different designations for the sources for which they collect emissions data at the point level (as
opposed to treating them as nonpoint area sources); no effort was made to strictly define what
would be considered a "major source" in the data collection effort.
The data request portion of the initial data collection effort was essentially completed by
June 2004. EIAG needed to establish a date for the receipt of data in order to complete the
15
-------
remaining tasks to develop the draft of the 2002 NEI. These tasks included processing the data
for upload to the NEI format, requesting and processing data from ESD, supplementing with
Department of Energy (DOE) and US EPA Clean Air Market Division (CAMD)-derived electric
generating unit (EGU) data, supplementing with TRI data if gaps remained, and identifying
duplicate facilities between these multiple data sources. Additionally, EPA reviewed and
augmented missing, out-of-range, and bad geographic coordinates and stack parameters; and
augmented missing particulate matter (PM) emissions. A draft of the 2002 NEI was posted in
February 2005 on EPA's FTP site. States, tribes, and local tribal agencies had three months to
review the draft and submit revisions. Revisions were due by May 1, 2005.
3.2 Initial Data Received from State, Local, Tribal and Regional Agencies
Table 3-2 lists the 73 agencies (in all 50 states plus the District of Columbia and 10
Tribes) for which point source inventory data were initially obtained in 2004. In addition, to
state, local, and tribal submittals one Regional Planning Organization (RPO), the Lake Michigan
Air Directors Consortium (LADCO) submitted data for wildfires, prescribed burning, and
agricultural burning. In Table 3-2 these fire files are listed under the relevant state. There were
no efforts by EIAG to review the inventory estimates for their accuracy or calculate new
emission estimates. The goal at this point was to compile whatever state, local, and tribal data
were available. Filling data gaps and evaluating the quality of the data are addressed later in this
process. Appendix A provides detailed contact information and summary statistics for data
submitted by each state, local agency, and tribe.
3.3 Initial Data Received from Trade Associations
One trade association (the American Chemistry Council) submitted data for 4,4'-
methylenediphenyl diisocyanate (MDI). These data were not incorporated into the draft, but
were incorporated into the final 2002 NEI.

3.4 EIAG Requested ESD Maximum Achievable Control Technology Inventory Data
and Facility Lists
State, local, and tribal databases represent the core of the point source inventory.
Inventory data were also requested from the EPA's ESD for MACT/residual risk source
categories. A list of MACT categories and their codes used in the NEI are in the the 2002 State
Lookup File, 02nei_lkup_states.zip. While ESD provided mostly HAP data, some MACT
categories do include CAP estimates as well.
Data specifically to be used in the 2002 NEI were provided for 19 MACT source
categories (Table 3-3). For most MACT and Section 112(k) Area Source Standards categories,
facility lists were prepared and these lists were used to assign category codes to state, local, tribal
and TRI-based facilities in the NEI. These lists were prepared by ESD engineers based on prior
20
-------
data collection efforts and their knowledge of the sources in each category. See Appendix B for
a complete listing of categories and the source of the facility list for each. While some lists were
collected solely for the 2002 efforts, some were based on the 1999 NEI. Table 3-4 lists the
facility list flags that appear in Appendix B.

After the draft 2002 NEI was compiled, ESD provided estimates of mercury emissions from
electric utilities that were incorporated into the final 2002 NEI. Additional changes to MACT
draft data included:
reapplying MACT codes based on additional facility matching and corrections to MACT
default tables;
assigning new MACT codes to stationary combustion turbines (MACT Code 0108) and
internal combustion engines (MACT Code 0105) based on fuel type;
revising estimates for MACT categories based on ESD comments to the draft NEI;
incorporating most recent data for mercury emissions from electric arc furnaces;
incorporating mercury emissions provided by EPA Region Nine for gold mines;
applying MACT codes and compliance codes to facilities formerly assigned a
"MultiMACT' code; and
applying MACT codes and compliance codes to facilities with newly assigned NAICS
codes.
3.5 Supplementing with TRI Data
To assess the NEI for source category and facility coverage, TRI data were used (EPA,
2004b). TRI is a publicly available EPA database that contains information on toxic chemical
releases reported annually by certain covered industry groups. This inventory was established
under the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA) and
expanded by the Pollution Prevention Act of 1990. The TRI contains both HAP and ammonia
22
-------
emissions data, and is used in the NEI to supplement reporting of these compounds. The purpose
of this TRI review was to determine if the tribal-, local-, state-, and ESD-combined databases
(referred to hereafter as the NEI) needed to be supplemented with data for facilities that reported
to TRI, but were not included in the NEI submittals. For facilities included in both the NEI and
TRI, it was assumed that the NEI data were more accurate and, thus, no revisions were made for
those facilities.
The TRI facilities missing from the NEI were identified through a process of elimination.
Facilities included in the NEI were matched against TRI-listed facilities using one or more of the
following parameters:
TRI ID;
County;
Facility name;
Facility address; and
Latitude and longitude coordinates.
TRI data can be identified in the NEI by the "T" data source code in the Emission record.
See the the 2002 State Lookup File, 02nei_lkup_states.zip for more information on data source
types.
3.6 Supplementing with DOE and CAMD Electric Utility Data
The NEI was also supplemented with data obtained from the DOE's Energy Information
Agency (EIA) (DOE, 2003) and EPA's CAMD Emission Tracking System/Continuous
Emissions Monitoring (ETS/CEM) data (EPA, 2004a) for EGUs. The detailed methodology
used to extract, process, and develop emissions estimates from these sources is discussed in the
document: "Documentation for the 2002 Electric Generating Unit (EGU) National Emissions
23
-------
Inventory (NEI)" (EPA, 2004c). These data are included in the NEI along with state, local or
tribal agency submitted emissions data for EGU sources. See Section 3.9 for a detailed
discussion on how DOE and CAMD data were merged with state, local, and tribal agency data.
After the draft 2002 NEI was released, EGU stack parameters were revised.
3.7 Processing State, Local, and Tribal Agency, MACT, and Industry Data Sets
All data sets provided to EIAG were first formatted to be consistent with each other and
the NEI Input Format (NIF). Several processing and screening steps were initially performed on
each of the state, local, tribal, ESD, TRI, and EGU databases as they were received. These steps
included:
Logging each file as received and recording summary statistics on the file;
Converting the files to NIF 3.0;
Setting primary keys on each table;
Removing duplicate records;
Screening for records that contain CAPs, ammonia, or HAPs on the CAA list of
188;
Correcting XY coordinate type;
Adding state abbreviation based on FIPS code;
Verifying/correcting control status;
Correcting referential integrity violations;
Checking/correcting miscellaneous data codes such as emission release point
type, emission type, and emission unit numerator; and
Conducting quality control (QC) on latitudes/longitudes and stack parameters and
defaulting missing or bad data.
24
-------
3.8 Distribution of Quality Control Reports
EPA created four QC reports which it distributed to states, tribes, and local agencies after
the initial receipt and processing of the data submittals and during its internal review period.
During this period, EPA also augmented some data elements. The QC reports were intended to
give states, tribes, and local agencies a chance to review augmented data, correct errors, and
provide comments on EPA's QC process. The four QC reports are as follows:
1) Data QC Report - summarizes structural problems with the data, e.g., data errors,
incorrect codes, data integrity issues, etc;
2) Latitude/Longitude QC Report - lists latitude/longitudes that failed QC review
and provides EPA defaulted coordinates;
3) Stack Parameters QC Report - lists stack parameters that failed QC review and
provides EPA defaulted parameters; and
4) Content QC Report - compares 2002 data to 1999 data, highlights potential
outliers, missing facilities, and missing pollutants.
The detailed QC and augmentation procedures used to generate QC reports 2, 3, and 4 are
given in EPA's NEI Quality Assurance and Data Augmentation for Point Sources (U.S. EPA,
2006).
After reports 1, 2, and 3 were issued, reviewers were asked to submit comments and
changes. EPA reviewed these comments and incorporated them into the draft 2002 Point Source
NEI whenever possible. If EPA disagreed with a proposed change or needed more information,
the revision was not processed for the draft, but it may have been incorporated into the final 2002
NEI. Report #4 was distributed in December, 2004, and the contents of this report were meant to
help state, local, and tribal agencies review their data and submit additional revisions by May 1,
2005. Revisions submitted by states, local agencies, and tribes during this final review period
are summarized in Table 3-5. EPA processed revisions received from states, local agencies and
25
-------
tribes and then conducted additional QA to identify remaining outliers. EPA corrected these
outliers with assistance from state, local agencies and tribes to produce the final 2002 NEI.
The Documentation for the Draft 2002 Point Source National Emissions Inventory (U.S.
EPA, 2005b) contains samples from each of these reports described above as well as a summary
table of which state, local and tribal agencies supplied comments on reports 1, 2 and 3. It also
contains the very detailed data QC reports generated for each state, local agency and tribal
original data submittal.

3.9 Blend-Merging (aka Data Selection)
Because the NEI is composed of databases submitted from multiple sources, there can be
overlapping estimates from one or more of these sources. The NEI blend-merge or data selection
process attempts to eliminate duplicates. It is important to note, however, that during the
27
-------
preparation of the draft NEI that no estimate was actually deleted from EPA's "master"
inventory. Estimates deemed as duplicative were simply "unselected" and thus did not appear in
any output or summary files. This method allowed EPA to track competing estimates, and refine
its merging or data selection routine for the final 2002 NEI using different rules of selection.
The original data selection routine is described in the documentation for the draft 2002 NEI
(EPA, 2005b). The modified routine used in the preparation of the final 2002 NEI is described
below.
Prior to any blend-merging, EPA must first match the facilities from the multiple data
sources and assign common IDs to facilities found in one or more dataset. In preparation for the
compilation of the integrated 2002 NEI, EIAG created a crosswalk of NEI HAP and CAP
facilities from the 1999 NEI. EIAG built this crosswalk by first matching HAP and CAP
facilities to one another and assigning unique identifiers to every facility in this crosswalkthe
NEI Unique Facility ID. Facilities found in both the HAP and CAP inventories should share the
same NEI Unique Facility ID. It is important to note that data providers sometimes use different
Site IDs for their CAP and HAP inventories. In the NEI, these different Site IDs are retained; the
common NEI Unique Facility ID indicates that sites are at the same facility. When state, local
and tribal data submittals were received in June 2004, EPA compared facilities from these
submittals to the crosswalk. When there was a name or local identifier match between the new
data set and the crosswalk, EPA verified that other information such as state, county, address, zip
code, TRI ID (or other type of ID), and latitude/longitude coordinates were identical. If so, both
of the sites received the corresponding NEI Unique Facility ID. Facilities not found in the
crosswalk were assigned a new NEI Unique Facility ID. More details on the NEI facility
matching process can be found in Pope et al., 2004. After NEI Unique Facility IDs were
assigned, data selection took place.
The data selection routine conducts two selection passes at the following grouping levels:
Facility (NEI Unique Facility ID), pollutant code, data source (ranked)
Facility (NEI Unique Facility ID), HAP category (ranked), data source (ranked)
28
-------
First Selection Pass
In the first selection pass, which is performed only for HAP emission estimates for the
matched facilities, the selection routine looks at state (S), local (L), tribal (B), TRI (T), ESD (M
or P), Industrial (PI), EGU (CAMD and 767/CAMD*) data except for mercury data and ranks
the estimates. The highest ranked estimate is selected from among the duplicates in the specified
grouping.
The ranking of the data sources from highest to lowest is as follows.1

MACT categories given the highest ranking ("P" codes) include: Small and Large
Muncipal Waste Combutors (MWCs), Medical Waste Incinerators, Brick and Structural Clay
Products Manufacturing, Electric Arc Furnaces (mercury only), and Coke Ovens. These data
were supplied by ESD engineers and are preferred because they are based on extensive source
test data, and/or a very complete inventory for the category.
29
-------
The results of both passes are evaluated, and a final selection decision is made. Two
passes are necessary, because if the selection is confined to specific pollutant codes or CAS
numbers, then pollutants with different pollutant codes, where one is reported by CAS number
and the other by HAP category, could be retained and result in double counting. For example,
pollutant code 195 (lead and compounds) will not appear to duplicate pollutant code 7439921
(lead), and both pollutants will get through the pollutant-specific selection pass.
Second Selection Pass
The second selection pass, therefore, looks for duplicative HAPs at the category level at a
facility, so that only one pollutant in a group is selected. Both pollutant specific and HAP
category selection passes are necessary, since the HAP category pass would deselect specific
pollutants in the same HAP category (e.g., chromium III vs. chromium VI).
Criteria pollutants are handled on a category basis only and therefore only the second
selection pass is conducted on CAPs. Specifically, there are many fractions of PM (PM-PRI,
PM-FIL, PM-CON, PM2.5-PRI, etc.) and for this selection process they are all categorized as
PM. This approach was taken to avoid blending PM data from different sources (because of the
relationship among the PM fractions).
It is important to note that data selection passes described above were not conducted on
SO2 and NOx emissions from EGUs monitored by CAMD, or mercury emissions for coal-fired
units developed by EPA. However, EPA conducted selection passes one and two on non-
mercury HAPs and selection pass two on all other criteria pollutants at these units. The handling
of SO2, NOx and mercury data is discussed below.
Special Treatment of EGUs
As discussed in Section 3.6, the NEI was also supplemented with data obtained from the
EPA's CAMD ETS/CEM (EPA, 2004a) for EGUs.
30
-------
The ETS/CEM data files contain heat input and NOx and SO2 emissions data that are
generally based on monitoring data. EPA requires that all coal units have continuous emission
monitors (CEMs) to report hourly data. Oil and gas units in general may, but are not required to,
have CEMs. For additional information about EPA's requirements, see
http://www.epa.gov/airmarket/monitoring/factsheet.html.
Because the N0X and S02 ETS/CEM emissions data are deemed "preferred" by EPA,
data for these units were given priority in the 2002 NEI. The first step in combining the CAMD
N0X and SO2 EGU emission data was to match the facilities from the multiple data sources and
assign a common ID-the NEI Unique Facility ID (strNTISitelD in tblPointSI). The data
provider's local Site IDs (strStateFacilityIdentifier in tblPointSI) and emission release point
records were retained.
After verifying that the facilities were mapped correctly, the CAMD units were mapped
to the reported state, local, or tribal units. Units were mapped based on their SCC and reported
emissions. Matches were not always 1:1. In some cases, one CAMD-reported unit was mapped
to multiple state-reported units, and vice versa. In matching cases, the CAMD ETS/CEM NOx
and SO2 emissions data replaced the reported state, local, and tribal N0X and SO2 emissions.
Again, the data provider's Unit IDs and emission release point records were retained. Thus, the
CAMD NOx and SO2 unit-level emissions records are linked to the data provider's process,
control equipment, and emission release point records.
In a few cases, the state, local or tribal agency did not have an existing S02 or NOx record
at the matching unit. In those cases, new emissions records with ETS values were added to the
agency's data. Again, these new records have the data provider's IDs.
In addition to merging S02 and NOx from CAMD with state, local, and tribal data, EPA
updated the mercury estimates for most of the coal-fired EGUs as well. Emission estimates for
particulate divalent mercury, elemental gaseous mercury, and gaseous divalent mercury were
31
-------
developed by EPA for coal-fired electric utility steam-generating units. The approach used to
develop the estimates was to update an emissions model that was originally developed to
determine the nationwide 1999 mercury estimates for all coal-fired electric utility steam-
generating units.
The 1999 emissions model was updated based on EIA Form 767 information primarily
for unit operating status changes, fuel type and amount burned, fuel moisture content, and air
pollution control configuration (U.S. DOE, 2003).
Although one goal of these merging exercises was to maintain the data provider's IDs as
the key identifiers in the inventory (while updating the estimates to match EPA's databases),
EPA also stored two of its important identifiers in alternate fields in the inventory - the ORIS
Facility Code and ORIS Boiler ID. DOE assigns its own facility ID - the Office of Regulatory
Information Systems (ORIS) Plant ID - to plants with EGUs. This ID was transferred to the
strORISFacilityCode in the tblPointSI. DOE also maintains a unit level ID - the ORIS Boiler ID
- and this ID is stored in the strORISBoiler ID field in tblPointEU.
The source of the S02, NOx and mercury estimates for the EGUs in the NEI can be
determined by consulting the data source field in tblPointEM. Table 3-6 presents a list of these
data sources along with a brief description of what they mean.
3.10 Particulate Matter Augmentation
In developing the NEI, the EPA requires that particulate matter (PM10-PRI, PM10-FIL,
PM2.5-PRI, PM2.5-FIL, and PM-CON) be submitted by state, local, and tribal agencies.
However, sometimes fewer PM terms are submitted. Therefore, the PM data need to be
augmented to achieve the required PM terms. For the draft NEI, EPA augmented PM data when
values could be filled in directly using the provided PM terms. In the final 2002 NEI, EPA
augmented all missing PM terms. All augmented or revised PM estimates are flagged with a
data source code of "A" or "A-R " The data source code of "A" indicates an augmented PM

record, while the code "A-R" indicates an existing PM record was first revised to make it
consistent with the remaining PM fractions prior to PM Augmentation. Details on PM
augmentation are described in the document, NEI Quality Assurance and Data Augmentation for
Point Sources (U.S. EPA, 2006).
In December 2005, PM was additionally augmented for a number of point sources.
Details on the additional augmentation of PM can be found on the CHIEF web site.
3.11 Boiler Augmentation
As industrial boilers have been generally undercounted in the NEI for HAPs, EPA
augmented HAP emissions for boilers in the final 2002 NEI. EPA created these augments by
comparing the HAP inventory to the CAP inventory and isolating facility/process combinations
with industrial boiler SCCs in the CAP inventory, but not in the HAP inventory. Next, activity
data for these industrial boilers were derived from the carbon monoxide (CO) records. Finally,
HAP records were created by cloning the CAP site, unit, process, etc. identifiers and multiplying
the HAP emissions factors by the derived activity data to obtain the estimate. Industrial boiler
HAP emissions factors were obtained from ESD. Augmented boiler estimates are flagged with
a data source code of "A-B" (augmented boiler).
3.12 Chromium Augmentation
EPA augmented HAP data with chromium estimates in those cases where the state, tribe,
or local agency provided a record for total chromium and either chromium (III) or chromium
(VI). EPA created the augment by subtracting the supplied chromium species from the total
chromium:
Chromium (III)
Chromium (VI)
= Total Chromium -
= Total Chromium -
Chromium (VI)
Chromium (III)
34
-------
After the augmented chromium was added to the inventory, the total chromium record was
deleted to avoid double-counting. If chromium VI emissions were greater than total chromium
emissions or chromium III emissions were greater than total chromium emissions, then total
chromium emissions were deleted and chromium III emissions were not generated. If chromium
III emissions were greater than total chromium emissions, then total chromium emissions were
deleted and chromium VI emissions were not generated. Augmented chromium estimates are
flagged with a data source of "A-C" (augmented chromium).

4.0 COMPILING THE INVENTORY DATA INTO THE NEI DATABASE
4.1 NIF 3.0 and EPA's Data Standards
One of the goals of compiling the NEI was to process all the state, local, and tribal
agency, ESD-supplied, TRI, and EGU inventory data into a common structure with consistently
defined data fields. A common data structure will help end users define standardized approaches
to reviewing and using the data. The NEI Input Format (NIF) version 3.0 as designed by EPA
allows for a variety of data transfer mechanisms to be used and is flexible enough to be
supported by many different database programs. More detailed information about the NIF can
be found at http//www.epa.gov/ttn/chief/nif/index.html.
The NIF 3.0 format conforms with the EPA's data standards for environmental
information collection and exchange. The data standards were developed by Environmental
Data Standards Council (EDSC)- sponsored action teams that include members representing
states, tribes, and federal agencies. All of these standards have been implemented in the 2002
NEI, as described below.
4.1.1 SIC/NAICS Data Standard
This standard includes ways to classify business activities, including industry
classifications, product classifications, and product codes. The Standard Industrial Classification
(SIC) System has been used for many years to provide a code system for the identification of
business activities. SIC codes are gradually being replaced by the North American Industry
Classification System (NAICS) codes that were adopted by Canada, Mexico, and the United
States in 1997.
To populate the NAICS code field, a crosswalk of SIC codes to NAICS codes was
developed. Several different parties have already developed crosswalks. The maps that have
been built to date were evaluated to come up with a preferred scheme for the NEI. Where there
36
-------
was a one-to-one correspondence between NAICS and SIC codes, the assignment was
straightforward. However, in those cases in which one SIC maps to many NAICS codes, the SIC
code was mapped to a less specific NAICs code (i.e., a 2, 3, or 4 digit code). For more
information as to how EIAG reviewed and defaulted this standard, see the NEI Quality
Assurance and Data Augmentation for Point Sources (U.S. EPA, 2006).
4.1.2 Latitude/Longitude Data Standard
The latitude/longitude standard consists of the group of data elements used for recording
horizontal and vertical coordinates and associated metadata that define a point on earth. This
standard will help users gauge the accuracy and reliability of a given set of coordinates. The
primary responsibility for populating these fields lies with the data submitter, as it is difficult if
not impossible to discern the origin of a latitude/longitude without being the primary author of
the data. EIAG was able to populate these fields whenever latitude/longitudes were obtained
from the TeleAtlas Geocoding EZ Locator Service (http://geocode.com). For more information
as to how EIAG reviewed and defaulted this standard, see the NEI Quality Assurance and Data
Augmentation for Point Sources (U.S. EPA, 2006).
4.1.3 Chemical Identification Data Standard
The Chemical Identification Data Standard provides for the use of common identifiers
throughout the EPA for all chemical substances regulated or monitored by EPA environmental
programs. This standard provides unique, unambiguous, chemically correct common names for
all chemicals substances and groupings in EPA's system, and will facilitate automated searches
for chemical substances across EPA programs and their databases. EIAG has posted a Chemical
Identification pollutant code lookup table that addresses this standard.
37
-------
4.1.4 Facility Identification Data Standard
The facility identification data standard consists of core data elements that properly
identify the location, the affiliated organizations, individual business activities, and the
environmental interest of a facility site. To implement this standard, EIAG mapped the NEI
facilities to the FRS (Federal Registry System) ID maintained by OEI. The FRS ID is found in
the NOF files in the strFacilityRegistryldentifier field and in the 2002 NEI Facility File.
4.1.5 Contact Standards
The contact standards provide a consistent method of describing the contact person
submitting data to the NEI. These standards include point of contact, address, and
communication information. All of these elements are found in the Transmittal table in the NIF
structure.
4.2 NOF 3.0 and Data Standards
EPA distributes data in the NEI Output Format (NOF) version 3.0. NOF contains the
data standards listed above as well as other data elements that help users understand the origin of
the data. For more information on the NOF data fields, see the NEI Quality Assurance and Data
Augmentation for Point Sources (U.S. EPA, 2006).
38
-------
5.0 FUTURE UPDATES TO THE 2002 NEI
The Historical Emissions Table contains the current 2002 NEI emissions values by
Facility ID and Pollutant code. This table contains emissions values from the original June 2004
submittals, February 2005 draft, and February 2006 final version. When two or more emissions
values were available for the same pollutant/facility in the draft, one value was chosen. The
"non-selected" values are presented in the table alongside the "selected" or reported values.
This table will be used to track future revisions to 2002 NEI point source data.
