# 1 I. INTRODUCTION

A. Overview
This report documents the data sources, methods, and results for updating the 2002 base year criteria air pollutant (CAP) and ammonia (NH 3 

# ) emissions inventories for point, area, and nonroad sources for the Central Regional Ai r Planning Association (CENRAP) Regional Planning Organization (RPO). The “Base A” 2002 inventory files completed during February 2005 were updated to incorporate comments provi ded by the CENRAP State, Local, and Tribal (S/L/T) agencies and the Emissions Inventory (EI) and Modeling Workgroups. As a result of the updates, the new inventory files are termed “B ase B”. Additional work completed under this work order include the development of Sparse Matrix Operator Kernel Emissions/Inventory Data Analyzer (SMOKE/IDA) input files for a 2018 projection year inventory for electricity generating units (EGUs) and for fires that occurred in Ontario during 2002.
The CENRAP region includes the states and trib al jurisdictions of Arkansas, Iowa, Kansas, Louisiana, Minnesota, Missouri, Nebraska, Okla homa, and Texas. CENRAP (and other RPOs) will use these inventories to support air qual ity modeling, State Implementation Plan (SIP) development, and implementation activities for the regional haze rule and fine particulate matter (PM) and ozone National Ambient Air Quality Standards (NAAQS).
The inventories and supporting data prepared include the following:

(1) Comprehensive, county-level, mass emissi ons and modeling inventories for point, area, and nonroad sources of 2002 emissions for the CAPs and NH 3 

# for the S/L/T agencies included in the CENRAP region; (2) Modeling inventory files c ontaining 2018 projection year emissions for EGUs; and (3) A modeling inventory for Ontario fires during 2002.
The mass emissions inventory files were prepar ed in the National Emissions Inventory (NEI) Input Format Version 3.0 (NIF 3.0). The mode ling inventory files were prepared in the SMOKE/IDA format. The revisions to the Base A point, area, and nonroa d inventories did not result in adding any new SCCs that were not already included in the temporal, speciation, and spatial allocation profiles for the CENRAP inventorie s. Therefore, there we re no revisions to the ancillary files containing the spatial, temporal, and speciation profile data.

The inventories include annual em issions for sulfur dioxide (SO 2 

# ), oxides of nitrogen (NO x 

# ), volatile organic compounds ( VOC), carbon monoxide (CO), NH 3 

# , and particles with an aerodynamic diameter less than or equal to a nominal 10 and 2.5 micrometers (i.e., primary PM 10 

# and PM 2.5 

# ). The inventories included summer da y, winter day, and average day emissions. However, not all agencies included daily emissions in their inventories, and, for the agencies that did, the temporal basis for the daily emissions varied between agencies. Consequently, the inventories did not contain a complete and cons istent set of daily emissions for all source categories and pollutants. Therefore, dail y emissions prepared by S/L/T agencies were maintained in the NIF files if they met quality assurance (QA) review requirements. However, CENRAP requested that the daily emissions not be included in the SMOKE input files. The

# 2 temporal profiles prepared for this project will be used to calcula te daily emissions. If needed, the daily emissions prepared by the agencies ma y be retrieved from the NIF database files.
The following data sources were used to update CENRAP’s Base A inventories:

(1) S/L/T agency comments on the “Base A” inventories; (2) S/L/T agency comments on the draft 2002 NEI; (3) Revisions to CENRAP-spons ored inventories; and (4) Comments from CENRAP’s EI and Modeling Workgroups.

The United States (U.S.) Environmental Protect ion Agency’s (EPA’s) format and content QA programs (and other QA checks not included in EP A’s QA software) were run on each inventory to identify format and/or data content issues (EPA, 2004a). E.H. Pechan & Associates, Inc. (Pechan) worked with the CENRAP’s EI and Modeling Workgroups and the S/L/T agencies to resolve QA issues and augment the inventories to fill data gaps in accordance with the Methods Plan and Quality Assurance Project Plan (QA PP) prepared for this project (CENRAP, 2005a; CENRAP, 2005b). The EI Workgroup and S/L/T agen cies reviewed the dr aft inventory files after updating the inventories, and the file s were updated to address their comments.
B. Summary of the 2002 Base Year Inventories
This section of the report provides a brief summa ry of the consolidated 2002 Base B inventories for the CENRAP region. Table 1 shows total annual emissions for CAPs and NH 3 

# for point, area, nonroad, and onroad sources. The sector contributing the highest emissions varies by pollutant. Point sources account for the highest percentage of total NO x 

# (35 percent) and SO 2 

# (83 percent) emissions. Area sources account for the highest percentage of total VOC (44 percent), primary PM 10 

# (PM10-PRI (93 percent)), primary PM 2.5 

# (PM25-PRI (81 percent)), and NH 3 

# (83.5 percent) emissions. Onroad source s account for the highest percentage of CO (57 percent) emissions. Onroad sources ac count for 24.5 percent and nonroad sources account for 17 percent of total VOC emissions. Onro ad sources account for 33 percent and nonroad sources account for 18.5 percent of total NO x 

# emissions.
Table 2a shows total annual emissions by state and pollutant for all f our sectors combined. Tables 2b through 2e show total annual emissions by state and pollutant for area, point, nonroad, and onroad sources, respectively. Tables A-1 through A-6 in Appendix A provide summaries of annual emissions by source category and sector for VOC, NO x 

# , CO, SO 2 

# , PM10-PRI and PM25- PRI, and NH 3 

# , respectively. The emissions in each tabl e are sorted in descending order with the highest emitting categories listed at the top of the table. The ta bles also show annual emissions as a percentage of total emissions from all s ectors, and the cumulative percentage contribution. Chapter III of this report identifies additional summaries of emissions, including county-level summaries that contain the data source codes that identify the origin and year of emissions data.
The Fond du Lac Band of the Minnesota Chippewa Tribe and the Leech Lake Band of Ojibwe Tribe each provided point and area source inventor ies. The point source inventories are included in the Base B inventory; however, the area so urce inventories are not because SMOKE is not currently programmed to process tribal area source data. Thus, the tribal area source inventories

# 3 are included in a separate NIF 3.0 database a nd the area source emissions are summarized in Table 2f (note that these area source emissions are not incl uded in Tables 1, 2a, and 2b).

The nonroad Base B inventor y includes carbon dioxide (CO 2 

# ) emissions, the point source inventory includes total primary and filterable particulate matte r (PM-PRI/-FIL) emissions, and the point and area source invent ories include filterable PM 10 

# (PM10-FIL), filterable PM 2.5 

# (PM25-FIL), and condensible PM (PM-CON) emissions. The emissions for these pollutants were carried in the mass emissions inventory files. However, th ese pollutants are not included in the summaries since the emissions for these pol lutants were not consistently reported by all S/L/T agencies for a given sector. In addition, AR is the only state that included PM10-PRI and PM25-PRI emissions for fugitive wind-blown dust em issions in its area source inventory. The wind-blown dust emissions are stored in the area miscellaneous sources inventory, and are included in the sector-level summaries (as geog enic and natural/biogeni c sources) described in Chapter III of this report.
C. Organization of the Report
In Chapter II of this report, section A provide s an introduction to the chapter and sections B through D present the data sources and methods a pplied to prepare the mass emissions inventory and SMOKE input files for point, area, and nonroad sources within the CENRAP region. Section E explains the data so urces and methods applied to prepare SMOKE IDA files for a 2018 projection year inventory for electricity generating units (EGUs) in the CENRAP region. Section F provides documentation of the SMOKE and RPO data exchange protocol files prepared under this project.
Chapter III and Appendix A provide summaries of the 2002 emissions inventories for point, area, nonroad, and onroad sources within the CENRAP re gion. Chapter IV presents the data sources and methods applied to prepare SMOKE input file s for 2002 fires in Ontario, Canada. Chapter V provides the references for this report.
D. Project Work Plan and Methods Document
At the beginning of this project, a draft wo rk plan and methods document was prepared and reviewed by the CENRAP EI and Modeli ng Workgroups (CENRAP, 2005a; CENRAP, 2005c). The Workgroups did not provide any comments on these two deliverables. Thus, the draft work plan and methods document was not revised. Ho wever, during the durati on of the project, the Workgroups requested additional re visions to the Base A point, area, and nonroad inventories after the draft work plan and methods documen t was prepared and reviewed by the Workgroups. This final report for the Base B inventory details all of the updates and refinements completed on the Base A inventory. However, due to time a nd resource constraints, the draft work plan and methods document was not revised to reflect this additional work.4Table 1.

# INVENTORIES FOR THE CENRAP REGION

A. Introduction
The following data sources were used to update CENRAP’s 2002 Base A inventories:

(5) S/L/T agency comments on the “Base A” inventories; (6) S/L/T agency comments on the draft 2002 NEI; (7) Revisions to CENRAP-spons ored inventories; and (8) Comments from CENRAP’s EI and Modeling Workgroups.
Table 3 provides a summary of the S/L/T agency data received for updating CENRAP’s Base A inventories. Prior to using the data to updat e the Base A inventories, Pechan performed QA review of the inventories to id entify (1) remaining QA issues that needed to be resolved through consultation with the agency and/or the EI and Modeling Workgroups, and (2) missing data that needed to be added to the inventories to suppor t air quality modeling studies. As a result of the QA review, and after consulting with KS and MO, it was agreed that the point source inventory data they provided would not be used in the Base B point source inventor y (see section II.B for additional details).

1 An “x” identifies the sector for which a S/L/T agency provided data to revise the Base A inventory. 2 Agency provided inventory that completely replaced its Base A inventory data. 3 Agency provided comments on CENRAP’s Base A inventory. 4 Agency provided comments on draft 2002 NEI that were used to update the Base A inventory. 5 Agency provided comments but comments not used per agreement with the agency. 6 Agency provided a new inventory not included in the Base A inventory.

# 9 After resolving the QA issues, the files were update d to revise or add data provided by the S/L/T agencies. In addition, the CENRAP’s Base A NONROAD model inve ntory was revised to correct input data for the oxyge n content of fuels and the SO 2 

# content of diesel fuel. Thus, the nonroad inventory for the NONROAD model categories was updated for all states that elected to use this inventory in the CENR AP inventory. Also, revisions were completed on all sectors to address comments from the EI and Modeling Workgroups.
The following sections B, C, and D provide the methods for updating CENRAP’s 2002 Base A inventories for point, area, and nonroad sources , respectively. Each section discusses the QA review that was conducted on the S/L/T inventories to identify QA issues that were corrected to support air quality modeling. Then, each secti on discusses the augmentation procedures that were applied to fill in missing data. These pro cedures identify supplemental data that S/L/T agencies provided to add to or replace data in their inventories, the CENRAP-sponsored inventories that were added to the inventories as approved by the S/L/T agencies, and the 2002 NEI categories that S/L/T agencies requested to be added to their inventories. The augmentation procedures also explain how missing PM emissions were estimated and a dded to the inventories after incorporating inventor y data supplied by S/L/T agencies, the CENRAP-sponsored inventory data, and data from the 2002 NEI.
Section E presents the data sources and methods for preparing the 2018 pr ojection year inventory for EGUs. Section F documents the SMOKE and RPO data exchange protocol files prepared under this project.
B. Point Source Inventory Methods

1. Data Sources
For each S/L/T inventory that provided updates, Table 4 provides a summary of the pollutants included in each inventory, and compares the num ber of counties in the inventory to the number of counties in the 2002 preliminary NEI and in each S/L/T agency. The table also compares the number of facilities in the S/L/T inventory to the number of facilitie s in the 2002 preliminary NEI.

The inventories obtained from EPA are in A ccess 2000 databases in NIF 3.0. Each inventory was loaded into an Oracle database in NIF 3.0 to combine the inventories into a single data set. Then, after loading the inventor ies into Oracle in NIF 3.0, the following updates were performed on the consolidated data set, if necessary:10Table 4.

Note, ultimately KS inventory comments were notused to update the Base A inventory.2Refers to the counties in the 2002 CENRAP modeling inventory which could include CENRAP-sponsored inventories for NH3, fires, and confined animal feeding operations.3NA = Not Applicable.

# 11 • Hazardous air pollutant (HAP) records were removed since the inventory will support regional haze, fine PM, and ozone modeling.

• Pollutant codes were corrected to make them NIF 3.0 compliant (e.g., update PMPRI pollutant code to PM-PRI). Additi onally, other codes were identified for remediation on a case-by-case basis.

• The NIF 3.0 submittal flag field, when populated by an agency, provides the directions needed to determine how to re vise the 2002 inventory. For this project, comment files obtained from EPA reflected comments on the draft NEI and not on CENRAP’s 2002 inventory. Therefore, Pech an reviewed the submittal flag codes, compared the comment file to the CENRAP inventory, and consulted with the S/L/T agency to verify what records in the comm ent file were to be used to revise the CENRAP inventory. Pechan adjusted the submittal flags as necessary to document the records in the comment file that re placed records in CENRAP’s 2002 inventory.

• Null values in the tribal code field were upda ted to ‘000’ since this field is a part of the data key that defines records as unique in all eight NIF tables.

• The following NIF plus fields were added to the Transmittal (TR), Site (SI), Emission Unit (EU), Emission Release Poin t (ER), Emission Process (EP), Emission Period (PE), Emission (EM), and Control Equipment (CE) tables:

• Data Source Codes:

Code Description S State agency-supplied data. L Local agency-supplied data. R Tribal agency-supplied data. P Regional Planning Organization. SC S/L/T agency Corrected. AUG-A PM Augmentation: ad-hoc change. AUG-C PM Augmentation: standard augmentation method. AUG-O PM Augmentation: set PMxx- FIL = PMxx-PRI where for SCCs starting with 10 (external fuel combustion) and 20 (internal fuel combustion). Note: emission factors and particle-size data for estimating condensible emissions for fuel combustion SCCs starting with 30 were not avai lable; therefore, condensible emissions were not estimated for these processes if an agency provided filterable and not primar y emissions for these processes. AUG-Z PM Augmentation: automated f ill-in of zero values where all PM for a particular process is zero. GENPARENT Data source where a pare nt record was system generated.

# 12 • Revision Date: This field indicates th e month and year during which the last revision was made to a record. For th e Base B inventory, for new or updated records, it is 0705.

• State Federal Information Processing Standa rd (FIPS): This field indicates the state FIPS code of the submittal.

• County FIPS: This field indicates th e county FIPS code of the submittal.

• The following NIF plus fields were added to the EM table:

• Emission Ton Value: This field indicate s the values of the emissions in tons. This field was used to prepare su mmaries of emissions on a consistent emission unit basis.

• Emission Type Period: This field indi cates the period of the Emission Type – either ANNUAL or NONANNUAL. This field was used to prepare summaries of annual emissions.

• CAP_HAP: This field identifies records for CAP versus records for HAPs. For the CENRAP inventory, the flag is CAP for all records.

• Year: This field indicates the year of the data; for this inventory, it is 2002.

2. QA Review

QA review on the inventories was conducted in accordance with the QA procedures specified in the QAPP for this project (CENRAP, 2005b).
The following data elements were reviewed to identify QA issues:

• Emission Release Point (ERP) or Stack Coordinates;

• ERP (Stack) Parameters;

• PM Emissions Consistency and Completeness;

• Control Devices and Efficiencies;

• Start and End Dates; and

• Annual and Daily Emissions Comparison.
As appropriate, individual S/L/T agencies were contacted with QA questions in order to receive direction on corrections.
a. County and Facility Coverage
S/L/T agencies which submitted complete replacement inventories or replacement facility information (Arkansas, Leech Lake) were compared to their previous year’s submittal as

# 13 appropriate to determine if there is a significant change in county coverage, facility coverage, or emissions.
b. Pollutant Coverage
S/L/T agencies which submitted complete replacem ent inventories (Arkansas, Leech Lake) were reviewed for pollutant coverage and other potentia l issues. Arkansas’ Base A inventory included emission data from the CENRAP-sponsored invent ories for confined animal feeding operations and planned burning. The CENRAP-sponsored emissions data were merged with Arkansas’ new inventory.
Arkansas, Minnesota, and Leech Lake include repl acements and/or revisions to their PM data. On processes where the PM data were replaced or revised with new data, the PM augmentation routine was applied. The QA review of the PM da ta is discussed further in the following section, and the augmentation procedures are discussed in section II.B.4.
c. Particulate Matter (PM) Emissions Consistency and Completeness Review
The following consistency checks were performed at the EM table data key level (for annual emissions) to compare PM emissions:

• If a process was associated with a PM em ission record, but was missing one or more of the following (as appropriate for the S ource Classification Code [SCC] [i.e., condensible PM (PM-CON) is associated with fuel combustion only]): PM10-FIL, PM10-PRI, PM25-FIL, PM25-PRI, or PM-CON, the record was flagged for review.

• The following equations were used to determine consistency:

PM10-FIL + PM-CON = PM10-PRI PM25-FIL + PM-CON = PM25-PRI PM-FIL + PM-CON = PM-PRI (as appropriate)

• The following comparisons were applied to determine consistency:

PM10-PRI >= PM10-FIL PM25-PRI >= PM25-FIL PM10-PRI >= PM-CON PM25-PRI >= PM-CON PM10-FIL >= PM25-FIL PM10-PRI >= PM25-PRI PM-PRI >= PM10-PRI (as appropriate) PM-PRI >= PM25-PRI (as appropriate) PM-FIL >= PM10-FIL (as appropriate) PM-FIL >= PM25-FIL (as appropriate)

# 14 If the data failed one of these checks it was di agnosed as an error. If a S/L/T agency did not provide corrections to these errors, the erro rs were corrected/filled in according to the augmentation procedure discussed in section II.B.4.

d. Emission Release Point (ERP) Coordinate Review
Location coordinates for new point sources were evaluated using geographic information system (GIS) mapping to determine if the coordinates we re within 0.5-kilometers of the boundary of the county in which the source was located. ERP reco rds with coordinates located more than 0.5, 1, 2, 3, 5, 7, and 10 or more kilometers from th eir county boundary, and coordinates that mapped outside of their state boundary were identified. Arkansas’ new point sour ce inventory contained what appeared to be new coordinates not include d in its Base A invent ory. However, Arkansas indicated that the ERP information had not changed significantly since the original submittal was submitted for ERP coordinate review. Coordinates for the Leech Lake submittal were manually reviewed and it was verified that the coordinates fell w ithin the tribal area boundaries.

e. ERP Parameter Review
The EPA’s QA guidance for diagnosing ERP issues for the point source NEI (EPA, 2004b) was applied to identify QA issues in the S/L/T point source inventories. The QA guidance involved diagnosing the correct assignment of the ERP type (i.e., stack or fugitive), parameters with zero values, parameters not within the range of va lues specified in the EPA’s QA procedures, and consistency checks (i.e., comparing calculated va lues against expected values). In many cases errors were due to defaulted zeros, and submitti ng agencies were requested to provide the value. In other cases, out-of-range errors were caused by unit conversion issues (e.g., stack parameters were in ft, ft/sec, cu ft/sec or degrees Fahrenheit). The data were corrected or filled in according to the ERP parameter augmentation pr ocedure discussed in section II.B.4.
f. Control Device Type and Control Efficiency Data Review
The CE codes in the “Primary Device Type Code” and “Secondary Device Type Code” fields were reviewed to identify invalid codes (i.e., codes that did not exist in the NIF 3.0 reference table) and missing codes (e.g., records with a null or uncontrolled code of 000 but with control efficiency data).
QA review of control efficiency data involved diagnosis of two t ypes of errors. First, records were reviewed to identify control efficiency values that were reported as a decimal rather than as a percent value. Records with control efficien cies with decimal values were flagged as a potential error (although not necessarily an error, since the real control efficiency may be less than 1 percent).

The second check identified record s where 100 percent control was reported in the CE table, but the emissions in the EM table were greater than zero and the rule effect iveness value in the EM table was null, zero, or 100 percent (implying 100 percent control of emissions). Because many agencies did not populate the rule effectivene ss field or a default value of zero was assigned, records with null or zero rule effectiveness va lues were included where the CE was 100 percent

# 15 and emissions were greater than zero. All new data submitted for updating CENRAP’s point source inventory passed these QA checks.
g. Start and End Date Checks
QA review was conducted to identify start date and end date values in the PE and EM tables to confirm consistency with the inventory year in th e transmittal table, and to confirm that the end date reported is greater than the start date re ported. This check did not identify any QA issues with the data used to update the Base A inventory.
h. Annual and Daily Emissions Comparison
The following QA checks were conducted to iden tify potential errors a ssociated with the incorrect reporting of dail y and/or annual emissions:

• Multiple records coded at the process level as emission type 30, but with different start and end dates. While not a true duplicate, th is may indicate an error or an inclusion of both annual and seasonal values. Only one record can be identified as the “ANNUAL” record.

• Multiple records coded at the process level (or SCC, in the case of area) as a daily emission type (27, 29, etc.) but with different start and end dates. While not a true duplicate, this may indicate an error or just an inclusion of addi tional types of daily emissions.

• Multiple records coded at the process level (o r SCC, in the case of area) with the same start and end date, but different emission type s. While not a true duplicate, this may indicate an error or just an inclusi on of additional types of daily emissions.
All new data submitted for updating CENRAP’s point source inventory passed these QA checks.
3. Responses from S/L/T Agencies
The S/L/T agencies provided responses to que stions about their data . When necessary, QA issues were summarized in Excel spreadsheets a nd sent to the agencies and the EI and Modeling Workgroups for review. The agencies or the Wo rkgroups then provided direction for correcting the issues either by telephone or by e-mail.
4. Gap Filling and Augmentation
The following discusses the augmentation procedures that were used to fill in missing data that were not supplied by the S/L/T agencies.

# 16 a. PM Augmentation
Pechan implemented procedures to estimate mi ssing pollutant data from data provided by the S/L/T agencies in order to develop a comple te set of PM10-PRI and PM25-PRI emissions to support air quality modeling.
The PM augmentation process gap-filled missing PM pollutant complements. For example, if a S/L/T agency provided only PM10-PRI pollutant s the PM augmentation process filled in the PM25-PRI pollutants. The steps in the PM augmentation process were as follows:

• Initial QA and remediation of S/L/T provided PM pollutants;

• Development of PM factor ratios based on factors from the Factor Information and REtrieval (FIRE) Data System (Versi on 6.2) and the PM Calculator (EPA, 2003; EPA, 2004c);

• Implementation of the ratios; and

• Presentation of PM augmentation results to S/L/T agencies for review and comment.
Note: An Access database accompanies this documentation - Reference Tables for PM Augmentation . This database contains the SCC Contro l Device Ratio table, the Emission Factors table and Emission Factors Crosstab table discussed in Step 2. Th e PM Calculator ratio table can be provided upon request – it contains all possi ble combinations for SCC and Control Device types that are available in the PM Calculator.
These steps are further detailed below.
1. Initial QA and Remediation of PM Pollutants
S/L/T agencies were initially presented with fi les that detailed potential inconsistencies and missing information in their PM pollutant invent ory. Inconsistencies in PM pollutants include the following:

• PM-PRI less than PM10-PRI, PM25-PR I, PM10-FIL, PM25-FIL, or PM-CON

• PM-FIL less than PM10-FIL, PM25-FIL

• PM10-PRI less than PM25-PRI, PM10-FIL, PM25-FIL or PM-CON

• PM10-FIL less than PM25-FIL

• PM25-PRI less than PM25-FIL or PM-CON

• The sum of PM10-FIL and PM-CON not equal to PM10-PRI

• The sum of PM25-FIL and PM-CON not equal to PM25-PRI
Potential missing information was summarized in a table which detailed the variety of cases provided by the S/L/T agency. For example, a S/L/T agency might have provided PM10-FIL and PM25-FIL for some processes, but for ot her processes only PM10-FIL was provided.
S/L/T agencies were asked to re view this information and provide corrections where possible. In general, corrections (or genera l directions) were provided in the case of the potential inconsistency issues. An example of a gene ral direction provided by a S/L/T agency was to

# 17 remove PM25-FIL where greater than PM10-FIL because the PM10-FIL was (in their particular case) known to be more reliable. In other cas es, the agency-provided specific process level pollutant corrections. In genera l, if specific direction was not provided by the agency, priority was given to the PM 10 

# number.
2. Development of PM Factor Ratio
The primary deliverable of this step of the process was the development of a table keyed by SCC, primary control device, and secondary contro l device. This table is called the SCC Control Device Ratios table. The table structure is show n in Table 5 which follows the discussion below.
This table was filled according to the following steps:

• Ratios (both condensible and noncondensib le) were added from FIRE for SCCs starting with 10* (external fuel combus tion) and 20* (internal fuel combustion) where there was a direct match between the provided SCC, and primary and secondary control devices.

• Ratios (non-condensable) were added from th e PM Calculator for SCCs starting with 10* and 20* where there was not a direct match between the provided SCC, and primary and secondary control devices. C ondensible ratios were added from the PM Calculator based on the uncontrolled SCC for these SCCs. In some cases, it was necessary to map the SCC and control device s to the PM calculator to find a match for the noncondensible ratios. In some cases, it was necessary to map the SCC to FIRE to find a match for condensible ratios.

• For natural gas, process gas and liquefied petroleum gas SCCs starting with 10* and 20*, it was assumed (based on FIRE emission factors trend) that the PM-PRI/PM10- PRI/PM25-PRI ratio was equal to 1. It was also assumed that the PM-FIL/PM10- FIL /PM25- FIL was equal to 1. Conde nsible ratios were calculated from uncontrolled FIRE emission factors based fo r these SCCs. In some cases it was necessary to map the SCC to FIRE to find a match for condensible ratios.

• Ratios for SCCs not like 10* and 20* were obta ined from the PM Calculator. It was assumed that the condensible component was zero.
Accompanying this document is a database co ntaining the SCC Control Device Ratios table. Additionally, the Emission Factors and Emission F actors Crosstab table (w hich are derived from FIRE) are provided. The Emission Factors Crosstab table contains the rati os developed from the Emission Factors table. The Emission Factors table contains detailed information on the emission factors used to develop the ratios.

Note: Ratios from the PM calculator were de veloped using a standard input of 100 TONS of uncontrolled PM-FIL emissions.

# 19 3. Implementation of the QA Ratios

In order to calculate the addi tional PM pollutants based on the SCC Control Device ratio table developed in the above step, a crosstab table was created from the EM table based on the following fields:

• State FIPS

• County FIPS

• Tribal Code

• Emission Unit identification (ID)

• Process ID

• Start Date

• End Date

• Emission Type

• SCC

• Primary Device Type

• Secondary Device Type
The primary and secondary device type fields were added based on information from the CE table. If control equipment information was not available these fields were defaulted to 000 (“UNCONTROLLED”). In the few cases where ther e was a conflict betwee n the control devices reported for the same process for PM pollutants (f or example, a PM10-PRI is listed as controlled, but PM-PRI did not have control information), th e control device type was selected based on the controlled pollutant.

In addition to the fields list ed above, the crosstab included the PM emission amounts for the particular process and a field th at indicated whether those emi ssions existed in the inventory. These fields are as follows:

• PM_PRI

• PM_FIL

• PM10_PRI

• PM10_FIL

• PM25_PRI

• PM25_FIL

• PM_CON

• PM_PRI_EXISTS

• PM_FIL_EXISTS

• PM10_PRI_EXISTS

• PM10_FIL_EXISTS

• PM25_PRI_EXISTS

• PM25_FIL_EXISTS

• PM_CON_EXISTS

# 20 The emission values are in the PM_P RI, PM_FIL, PM10_PRI, PM10_FIL, PM25_PRI, PM25_FIL, PM_CON fields. The _EXISTS field i ndicates whether the pollutant was provided by the S/L/T agency. A zero indi cates that the pollutant was not provided; a number greater than zero (usually one) indicates that it was provided by the S/L/T agency.
Prior to the development of this crosstab, the EM table was filled in as much as possible using basic assumptions. For example, if the S/L/T ag ency provided emissions that were equal to zero for PMs for a particular process, it was assumed that all PMs for that process were zero and they were filled in accordingly. Since the a ssumption was that for non 10* and 20* SCCs, the condensible value was zero – that would le ad to PM10-FIL = PM10-PRI and PM25-FIL = PM25-PRI and PM-FIL = PM-PRI. Given that a ssumption, values for thes e pollutants were also filled in. After this data inse rtion, a subset of the crosstab was created. This subset only contained processes that require d additional augmentation. The SCC control device type ratio table described in step 2 was based on only those SCC and cont rol device types that required augmentation.
The next step was to fill in the missing informa tion in this crosstab us ing the information found in the SCC Control Device Ratio table.
In calculating PM complement pollutants, prio rity was given to calculating –PRI and –CON pollutants. FIL pollutants were only calculated if necessary to calculate other pollutants or if it was a by-product of this calculation.
In augmenting the PM pollutants the non 10* and 20* SCCs were augmented first, with order given to augmenting based on PM 10 

# where available, PM 25 

# where available, and then PM .
Augmenting the PM pollutants for the 10* and 20* SCCs is more complicated, but the basic approach was to augment based on PM 10 

# (FIL or PRI) where available, PM 2.5 

# (FIL or PRI) where available, and then PM (FIL or PRI) if PM 10 

# or PM 2.5 

# variations were not available. Where both PM 10 

# (FIL or PRI) and PM 2.5 

# (FIL or PRI) variations were both available, the calculation for PM-CON was generally driven from the PM 10 

# number and the complements as necessary were back calculated. Where a –PRI emission factor ratio was required and wa s not available the – FIL emission factor ratio was used.

After calculations, the data was QA checked to ensure that the calculations resulted in consistent values for the PM complement. On a few occasions, the mix of ratio value and the pollutants and values provided by the S/L/T agency resulted in negative values when –FIL was backcalculated. In this case the negative –FIL value was set to zero a nd the –PRI value was readjusted.

The resultant PM table has the format described in Table 6.

Note: There are some high condensible ratios that were calculated for some SCC device type combinations. In most cases these high condensible ratios were the result of the back calculation of PM-CON from PM10-PRI or PM25-PRI records. Since the state had

# 21 already provided the PMxx-PRI records, th ese PM-CON values were not added to the inventory.

# 22 The data source code field is used to identify r ecords that are added to the inventory to complete the set of PM10-PRI and PM25-PRI em issions needed to support modeling.

b. ERP Coordinates
If a S/L/T agency did not provide corrections for ERP coordinates that map more than 5 km outside of the county boundary, or provide coordinates for ERP r ecords that did not have any coordinates in the S/L/T inventory, the followi ng procedures were applied to replace the coordinates:

• Coordinates for other ERPs at the same facility, if available, that map within the county;

• Coordinates for the centroid of the zip code for a facility if a valid zip code is provided or can be obtained from the agency if it is not valid; or

• County centroid coordinates.
The zip code was taken from the SI NIF 3.0 table. The zip code was compared to a reference table of valid zip codes to verify that it is an active zip code a nd exists in the state and county reported in the inventory. For example, a zip code may be invalid if it is for the mailing address or address of a facility’s parent company rather than the address of the facility’s loca tion. If a valid zip code for a facility was not identified, Pechan used the centroid for the facility’s county as a last resort.

c. ERP Parameters
If valid ERP parameters were not provided by the S/L/T agency, Pechan applied the ERP augmentation procedures for the 2002 point sour ce NEI (EPA, 2004b). It has been determined that the augmentation procedures in this do cument regarding SCC-specific ERP types and temperatures are difficult to resolve. When th is situation occurs, pref erence was given to the state-supplied ERP type and SCC. For example, the procedures do not account for cases where an emission unit has two processes with one define d as a stack source and the other as a fugitive source. Therefore, the S/L/T-supplied ERP t ype was used when this situation occurred.
d. Control Device Type and Control Efficiency Data
If a S/L/T agency did provide valid control device type codes to replace invalid codes identified in the inventory, Pechan changed the valid NIF 3.0 code of 099 for miscellaneous control devices. In the case of modeled data where no control device information was provided, the records were left unchanged.
Pechan expected that control equipment data i ssues would be resolved through consultation with the S/LT Agencies. Default augmentation proce dures were developed and applied to resolve control efficiency issues. In the event that c ontrol efficiency issues were not resolved, Pechan documented the QA issues in the final report.

# 23 5. Revisions to Address Comments
The following items were revised per S/L/T agency instructions:

a. Arkansas
Arkansas sent a complete replacement inventor y. Arkansas confirmed that they revised the SCCs and emissions in this new inventory. Ther efore, the previous Base A inventory was used as a guide for correcting ER coordi nates and stacks and other QA issues.
County 777 information was removed from the enti re inventory (4 facilities with 34 emission records).

CE
It was noted by Arkansas that they had not sent any CE records. They confirmed this as intentional.

EM

Removed PM-PRI and PM-FIL with emission numer ic values of 0 (2,437 records) and 8 PM10- FIL/PRI records where the remaining PMxx-FIL/PRI information was non-zero.
Updated emission calculation method code from 4 to 04 (1,706 records).

Material codes of “0” we re nulled out (44 records).

Material IO codes of “U” we re nulled out (44 records).

Nulled out the invalid factor unit denominator value of “UNK”, or nulled out the factor unit denominator value if the factor un it numerator was null (44 records).
Where PM25-PRI values were greater than PM10 -PRI values, the PM25-PRI values were set equal to PM10-PRI values pe r instruction from the state.

Note: The NH 3 

# emissions in Arkansas’ new inventor y decreased considerably from the emissions in the Base A inventory. A comparison of the emissions was provided to Arkansas for review and confirmation that th e revised emissions are correct.

PE

Material codes of “0” we re nulled out (6 records).

Material IO codes of “U” we re nulled out (6 records).
Nulled out throughput unit numerator wh ere noted as “UNK” (6 records).

# 24 EP
The Arkansas inventory contained six inactive SCCs (i.e., SCCs in EPA’s February 2004 master list that are identified as no l onger used by EPA) that were changed to active SCCs as follows:

• 28888802 was replaced by 28888801

• 30800197 was replaced by 30800199

• 30703096 was replaced by 3070399

• 30703098 was replaced by 3070399

• 30699998 was replaced by 30699999

• 30700798 was replaced by 30700799
Updated one EP record to reset its operating percentages for the 4 seasons from all 24s to all 25s in order to make the sum of activity consistent.

ER
Where EP was parentless, ER records were adde d to the inventory. The ERP type was set to “01” if total stack emissions for all pollutants combined was less than or equal to 100 tons per year, or to “02” if total stack emissions for al l pollutants combined was more than 100 tons per year.
21 invalid ER types were updated based on the Base A inventory.
Updated 107 of Arkansas coordina tes based on Base A inventory.
Stack augmentation and coordinate augmentati on was implemented on any remaining missing or invalid values.

EU
One emission unit record was generated in order to maintain referential integrity.

SI
Two site records were generated in order to maintain referential integrity.

TR
The affiliation type “report_certifier” was changed to “Report Certifier”.

b. Iowa

# 25 Iowa provided additions a nd revisions to their SO 2 

# emissions. These revisions were applied to their submittal.

EM

Emission revisions were made to records where th e data keys in the comments matched those in the inventory. Emission records were added to the Base B inventory where there was no data key match. In order to maintain referential inte grity, records in the comment file were added to the ER, EU, EP, and PE tables. In addition, a co rrection was made to the start and end dates to ensure that they all started w ith 2002, in some cases, 2003 was used.

c. Kansas
Kansas provided comments to the EPA; however , after an initial inco rporation of emission comments into the inventory – it was determined through state review that the comments did not apply to the CENRAP inventory. These emissions were restored to their original values. Essentially, the Kansas i nventory remained unchanged.

d. Minnesota
Minnesota submitted new information for municipa l airport emissions as well as revisions to their PM data.

ER
When inserting the new municipal airport emissi ons, 236 fugitive records we re defaulted to the fugitive defaults. Eight records noted as stacks were defaulted to stack defaults. Coordinates were compared manually either to the previous Minnesota submittal which had been QA checked or manually compared to known county boundaries.

EM
When incorporating the new municipal airport in formation, it was determined that there were 13 duplicate records and one inconsis tent ER-EU combination for NH 3 

# . The new information submitted was selected over the previous information.
Minnesota included updates to their PM informati on. Where the PM values were new, they were added to the inventory (after re moving previously augmented data). Where the PM values were revisions, the records were revi sed (after removing previously augmented data). When the PM QA check indicated that there were significant discrepancies between the relative values of PM10-PRI and PM25-PRI, it was determined thr ough consultation with th e state there was a problem in the export program that the state used to create the NIF 3.0 text file. Essentially, it was truncating the exponential pa rt of the emission numeric va lue in the file. Minnesota provided a corrected file. This corrected file was used to update the PM25-FIL/PRI values. After these values were incorporated, there we re still several comparative problems. Upon review, it was determined that a number of th ese comparative problems were due to rounding –

# 26 essentially comparing numbers in this fashion - PM10-PRI = 0.01999 and PM25-PRI = 0.02. The program would flag an error, even though it was a result of rounding. In these cases, the values were rounded appropriately. For 55 reco rds, the PM25-PRI values were set to the calculated value in order to resolve this type of issue. After resolving these values, the PM augmentation procedure was run.
Wildfires and Agricultu ral Field Burning
For the Base A modeling effort, the Midwest RP O’s point source invent ory for wildfires (SCC 2810001000) and agricultural field burning (SCC 2801500000) was to be used for Minnesota. The point source inventory was included in the NIF 3.0 file for Minnesota to support development of emissions summaries (the Midw est RPO provided the inve ntory in point source SMOKE input format). However, it was learne d that the Midwest RPO point source inventory was not being used for modeling so the 2002 point source wildfire and agricultural field burning emissions data were removed from the Base B poi nt source inventory and re stored to the Base B area source inventory.

e. Leech Lake
Leech Lake provided a new inventory that was not included in the Base A inventory.

ER
Leech Lake did not provide stack information fo r a fugitive ERP. This was defaulted to the stated default fugitive ERP values.
Leech Lake did not provide exit velocity and ex it flow information for two ERPs. These were defaulted according to the methods document.

EM
Leech Lake did not provide PM25-PRI emissi ons. For the point source SCCs, PM25-PRI emissions were estimated based on the PM a ugmentation methods. For the single area source SCC for prescribed burning, the PM25-PRI emi ssions were estimated by dividing the PM10-PRI emissions by a ratio of 1.14. This ratio is the lower of two valu es (1.18 and 1.14) most commonly used by the Midwest RPOduring the development of the Minnesota prescribed burning inventory.
An examination of duplicates between tribal information and state information yielded one potential site duplicate – the Cl oquet County municipal airport is listed in both the Minnesota (27017-000-27017XCOQ) and Leech Lake (00000-407- 05) inventories. The airport emissions in the two inventories are signifi cantly different (29 tons of CO for Minnesota and .04 tons of CO for the tribe – the largest emission set) and there was insufficient information to determine if the emissions were duplicated when combined into the Base B inventory. The prescribed burning emissions for Leech Lake were also compared to the Minnesota prescribed burning inventory, and it was determined that ther e were no common ERP coordinates or other

# 27 information to indicate duplication of data. T hus, the airport emissions and prescribed burning emissions in Leech Lake’s inventory were in cluded in the Base B point source inventory.

f. Missouri
Missouri provided a complete replacement i nventory; however, upon further discussion and agreement with Missouri, the replacement invent ory was not use to update the Base A inventory.

g. All CENRAP S/L/T agencies - Office of Regulatory Information Systems (ORIS) and ORIS Boiler ID Updates

The ORIS identifiers in the SI and EU tabl e were updated based on the crosswalk entitled CENRAPxwalk051005.mdb with modifications made for some emission un it identifier changes made by Arkansas. The revised crosswalk in cluding the Arkansas changes was delivered to CENRAP on August 11, 2005.

h

. Stack Parameter updates per CENRAP instructions

In addition to individual state submittals of da ta, stack parameter corrections were supplied to Pechan through CENRAP. These stack parameter comments affected 20 ERP records (4 in Iowa, 6 in Kansas, 5 in Louisiana, and 5 in Oklahoma) in one set of comments, and 15 records for Arkansas in another set of comments. There were some initial QA issues with the flow rate calculation; however, these issues were resolv ed by CENRAP and the revised comments were used to update the Base A inventory.
6. QA Review of Final Inventory

Final QA checks were run on the re vised point source inventory da ta set to ensure that all corrections provided by the S/L/T agencies were in corporated into the Base B inventory and that there were no remaining QA issues that could be addressed duri ng the duration of the project. After exporting the inventory in Oracle to an Access database in NIF 3.0, the EPA QA program was run on the Access database and the QA output wa s reviewed to verify that all QA issues that could be addressed were resolved (EPA, 2004a)
This file accompanies this documentation with the specific details included. The following summarizes the remaining QA issues that could not be addressed duri ng the duration of this project (listed by table):

CE
Primary device type codes are null for the conf ined animal feeding operations and planned burning (forest and rangeland). Th e data originates from the CENRAP-sponsored inventories for these categories. Missouri also has null primary device types for the major ity of the CE records it provided for NH 3 

# emissions.

EM

# 28 The EPA QA program indicated that some emissi ons were outside the expected range. While this is a guideline and not a sp ecific error, this listing coul d be reviewed for high values.

PE

There are a few (32) records with the units M2 and MASS that were not yet in the EPA QA program units reference table.
There are a few (8) remaining records with operating times outside the EPA QA program ranges.

EP
There are a few (9) remaining records with opera ting parameters and seasonal sums outside the expected range.
The SCC 30202000 has not yet been added to the EPA QA program SCC reference table.

ER
A significant number of records are missing the s upplementary coordinate reference information (Horizontal data measure, hor izontal data accuracy, horiz ontal collection method code).

Several records indicate coordinates outside of county boundaries – the reasons why this may occur were explained in the coordinate a ugmentation section earli er in this document.
Several records also indicate stack paramete rs outside of ranges expected by the EPA QA program. This is due either to the S/L/T agency specifically requesting not to change the values or to default values in the EPA table wh ich fall outside of the EPA QA program ranges.

EU

Standard industrial classification (SIC) code 3041 is not in the SIC code table.

SI
The inventories (p articularly the NH 3 

# inventory for confined animal feeding operations) did not provide zip code information with the site data . This accounts for a tremendous number of the invalid zip code errors found when running the EPA QA program. There are other records with zip code errors in addition to th ese; however, these inventories ar e the source of the majority of these errors.
NAICs codes are missing or invalid on some record s (470), primarily in Nebraska and Oklahoma which did not provide comments during this tim e. The location address is missing for some records in Minnesota and Nebraska.

# 29 TR
Some records are missing the transaction creation date information.
C. Area Source Inventory Methods

1. Data Sources
The states of AR, TX, and MN provided comment s for updating the Base A inventory. AR and MN provided comments on the Base A inventor y, and TX provided comments on the draft 2002 nonpoint NEI that were applied to update the Base A inventory. The Leech Lake Band of Ojibwe Tribe provided a new area source inve ntory. In addition, the EI and Modeling Workgroups provided several comments resulting in revisions to the ar ea source inventory. Documentation of the revisions made to the Ba se A inventory are provided in section II.C.5.
The data files that the states provided for updati ng the Base A inventory were loaded into Oracle in NIF 3.0 into one data set. Then, the fo llowing updates were performed on the consolidated data set, if necessary:

• HAP records were removed since the inventor y will support region al haze, fine PM, and ozone modeling.

• Pollutant codes were corrected to make them NIF 3.0 compliant (e.g., update PMPRI pollutant code to PM-PRI). Additi onally, other codes were identified for remediation on a case-by-case basis.

• The NIF 3.0 submittal flag field, when populated by an agency, provides the directions needed to determine how to re vise the 2002 inventory. TX’s comment file reflected comments on the draft NEI and not on CENRAP’s 2002 inventory. Therefore, Pechan reviewed the submittal fl ag codes, compared the comment file to the CENRAP inventory, and consulted with TX to verify what records in the comment file were to be used to revise the CENRAP inventory. Pechan adjusted the submittal flags as necessary to document the records in the comment file that replaced records in CENRAP’s 2002 inventory.

• Null values in the tribal code field were upda ted to ‘000’ since this field is a part of the data key that defines records as unique in all five NIF tables.
The following NIF plus fields were adde d to the EP, PE, EM, and CE tables:

• Data Source Codes:
For the area and nonroad inventory data, the da ta source codes were based on the following 9- character format:
[Data Origin]-[Year]-[Grown/Not Grown/Ca rried Forward]-[PM Augmentation Code]

# 30 Code Field Length Data Origin 1 Year 3 (including leading hyphen) Grown/Not Grown/Carried Forwar d 2 (including leading hyphen) PM Augmentation 3 (including leading hyphen)
Data Origin Codes
Code Description S State agency-supplied data L Local agency-supplied data R Tribal agency-supplied data P Regional Planning Organization-generated data E EPA/Emission Factor and Invent ory Group (EFIG)-generated data

Year Codes
Year for which data were supplied (e.g., Year = -02 for 2002), or from which prior year data were taken (e.g., Year = -99 for 1999; -01=2001).

Grown/Carried Forward/Not Grown Codes
Code Description -G Used when emissions in a pre-2002 i nventory were grown to represent 2002 emissions. -F Used when emissions in a pre-2002 inventory were carried forward and included in the 2002 inventory w ithout adjustment for growth. -X Used when the emissions were not grown or were not carried forward. For example, X was used when emissions were calculated for the 2002 inventory using 2002 activity, or when data we re replaced with 2002 S/L/T data.
PM Augmentation Codes
-PA PM Augmented Emissions: Record for PM 10 

# /PM 2.5 

# emissions that were updated or added using ad-hoc updates. -PC PM Augmented Emissions: Record added for PM 10 

# /PM 2.5 

# emissions estimated using the PM Calculator. -PR PM Augmented Emissions: Record added for PM 10 

# /PM 2.5 

# emissions estimated using ratios of PM 10 

# -to-PM or PM 2.5 

# -to-PM 10 

# . If PM 10 

# and PM 2.5 

# emissions were equal and one of the pollutants was assigned this code, the ratio was assumed to be 1. -VR Missing pollutant estimated by multiplying the ratio of the missing pollutant emission factor to the VOC emission f actor by the VOC emissions supplied by the S/L/T agency. This method was applied to estimate missing pollutant emissions in the 2002 NEI only. Records with this data source code in

# 31 CENRAP’s Base B inventory indicate that the data were copied from the NEI as directed by CENRAP agency comments. -NR Missing pollutant estimated by multiplying the ratio of the missing pollutant emission factor to the NO x 

# emission factor by the NO x 

# emissions supplied by the S/L/T agency. This method was applied to estimate missing pollutant emissions in the 2002 NEI only. Records with this data source code in CENRAP’s Base B inventory indicate that the data were copied from the NEI as directed by CENRAP agency comments.

2 QA Review

QA review was conducted on the S/L/T area sour ce inventories in accordance with the QA procedures specified in the QAPP for this pr oject (CENRAP, 2005b). The following discusses the QA checks that were completed during preparation of the Base B inventory.
a. County and SCC Coverage
The county coverage in the state inventories appeared to be reasonable for all states. The SCC coverage was difficult to evaluate simply by s howing a count of the number of SCCs by state. The EI and Modeling Workgroups reviewed summ aries comparing the Base B to the Base A inventory and provided comments that are explained under section II.C.5.
b. Pollutant Coverage
The pollutant coverage in the S/L/T inventories was complete for all pollutants except for PM 10 

# and PM 2.5 

# . Diagnosis and resolution of PM 10 

# and PM 2.5 

# pollutant emissions is discussed later in section II.C.5.
d. Additional QA for the CENRAP Area Source Inventory
The following explains additional QA that was performed for the CENRAP inventory. The following data elements were reviewed to identify QA issues:

• Range Errors;

• PM Emissions Consistency and Completeness;

• Control Device Codes and Control Efficiency Values;

• Start and End Dates;

• Annual and Daily Emissions Comparison; and

• Comparison of Base B to the Base A inventory.
As appropriate, individual S/L/T agencies were contacted with QA questions in order to receive direction on corrections.

# 32 Range Errors
The EPA’s QA program was run on MN’s and TX’s comment files. The range errors identified by the QA program were deemed acceptable. Note that according to EPA, the ranges to which values in inventories are compared represent “ normal” ranges that are based on percentiles from previous inventories. The range values are conservative in that EPA wants to identify suspicious values even though the values may be real (Thompson, 2002).
PM Emissions Consistency and Completeness Review
The following consistency checks were performed at the EM table data key level (for annual emissions) to compare PM emissions:

• If an SCC was associated with a PM emission record, but was missing one or more of the following (as appropriate for the SCC [i.e., PM-CON is associated with fuel combustion only]): PM10-FIL, PM10-PRI, PM25-FIL, PM25-PRI, or PM-CON, the record was flagged for review.

• The following equations were used to determine consistency:

PM10-FIL + PM-CON = PM10-PRI PM25-FIL + PM-CON = PM25-PRI

• The following comparisons were made to determine consistency:

PM10-PRI >= PM10-FIL PM25-PRI >= PM25-FIL PM10-PRI >= PM-CON PM25-PRI >= PM-CON PM10-FIL >= PM25-FIL PM10-PRI >= PM25-PRI

If the data failed one of these checks it was di agnosed as an error. If a S/L/T agency did not provide corrections to these erro rs, the errors were corrected/fil led according to an augmentation procedure explained in se ctions II.C.4 and II.C.5.
For information purposes, all PM-PRI and PM-FIL records were flagged to indicate that these pollutants were included instead of, or in addition to, the standard PM 10 

# , PM 2.5 

# , and PM-CON pollutants.
TX’s area source inventory had many records th at did not meet the PM consistency and completeness. Many of the errors occurred as a result of TX providing revisions on filterable emissions and not revising the primary emissions. Also, TX added daily filterable emissions for many categories but did not provi de daily primary emissions. TX was consulted on how to resolve the PM issues and TX provided di rections on how to correct the issues.

# 33 Control Device Type and Control Efficiency Data Review
The control equipment codes in the “Primary Device Type Code” and “Secondary Device Type Code” fields were reviewed to identify invalid codes (i.e., codes that did not exist in the NIF 3.0 reference table) and missing codes (e.g., records w ith a null or uncontrolled code of 000 but with control efficiency data).
QA review of control efficiency data involved diagnosis of two t ypes of errors. First, records were reviewed to identify control efficiency values that were reported as a decimal rather than as a percent value. Records with control efficien cies with decimal values were flagged as a potential error (although not necessarily an error, since the real control efficiency may be less than 1 percent). Records with a 1 percent control efficiency valu e were also identified for review by the S/L/T agency to determine if the value was reported as a decimal in its internal data system but rounded to 1 percent when the data were converted to NIF 3.0.

The second check identified record s where 100 percent control was reported in the CE table, but the emissions in the EM table were greater than zero and the rule effect iveness value in the EM table was null, zero, or 100 percent (implying 100 percent control of emissions). Because many agencies did not populate the rule effectivene ss field or a default value of zero was assigned, records with null or zero rule effectiveness va lues were included where the CE was 100 percent and emissions were greater than zero. For record s that met these criteria, Pechan consulted with the S/L/T agency to determine if correcti ons were needed to any of the fields.

Start and End Date Checks
The year in the start and end da te values in the PE and EM ta bles were reviewed to confirm consistency with the inventory year in the tran smittal table, and to confirm that the end date reported was greater than the start date reported.
Annual and Daily Emissions Comparison

The S/L/T inventories were revi ewed to determine if any of the following conditions existed:

• Multiple records coded at the SCC level as emission type 30, but with different start and end dates. While not a true duplicate, this may indicate an error or inclusion of both annual and seasonal values.

• Multiple records coded at the SCC level as a daily emission type (27, 29, etc.) but with different start and end dates. While not a true duplicate, this may indicate an error or just inclusion of addi tional types of daily emissions.

• Multiple records coded at the SCC level with the same start and end date, but different emission types. While not a true duplicate, this may indicate an error or just inclusion of additiona l types of daily emissions.

# 34 • Any “DAILY” type record that was mi ssing its associated “ANNUAL” record was flagged for review.

• Any “DAILY” type record that was great er than its associated “ANNUAL” record was flagged for review.
3. Responses from S/L/T Agencies
The S/L/T agencies provided responses to ques tions about their data. The agencies or the Workgroups then provided direc tion for correcting the issues either by telephone or by e-mail. For AR and TX, QA issues were summarized in Ex cel spreadsheets and sent to the agencies, and the agencies provided their responses to the issues in the Excel spreadsheets. Table 7 identifies the files that document the QA issues and agen cy responses. The first spreadsheet in each QA Summary Report defines the remaining spreadsh eets in the Excel Workbook file and provides instructions for communicating revisions.

S/L/T Agency Excel Workbook File Name of QA Summary Report AR AR_QA_Report_060705.xls TX TX_QA_Report_071405.xls


# 4. Gap Filling and Augmentation
CENRAP-sponsored inventory data were added to the inventories as reque sted either by the S/L agencies or by the EI and Modeling Workgroups. Procedures for resolving issues with PM emissions in the comment files or to add PM emissions missing from the comment and Base A inventory files were resolved through consultation with the S/L agencies.

5. Revisions to Address Comments
The following details the revisions made to the Base A inventory:

a. Arkansas

NH 3 

# Emissions

To be consistent with the NH 3 

# categories included for the othe r CENRAP states, the following NH 3 

# categories in the CENRAP-sponsored area sour ce inventory were added to the 2002 Base B inventory for AR:
SCC SCC Description 2630020000 Wastewater Treatment : Publ ic Owned : Total Processed; 2620030000 Landfills : Municipal : Total; 2806010000 Domestic Animals Waste Emissions : Cats; 2806015000 Domestic Animals Waste Emissions : Dogs; 2807020001 Wild Animals Waste Emissions : Bears : Black Bears;

# 35 2807020002 Wild Animals Waste Emissions : Bears : Grizzly Bears; 2807025000 Wild Animals Waste Emissions : Elk; and 2807030000 Wild Animals Waste Emissions : Deer.
Emissions for grizzly bears are zero; but were included in the inventory for completeness.
Agricultural Field Burning (SCCs starting with 2801500xxx)
The Base A inventory contai ned VOC, CO, PM10-PRI, and PM25-PRI emissions provided by AR. At AR’s request, AR’s state invent ory was replaced with the CENRAP-sponsored inventory. The activity data for the CENRAP-s ponsored inventory were developed by surveying local agricultural extension service agents wh ich are believed to provide better spatial and temporal resolution of agricultural field burni ng activity than the methods that were used for AR’s inventory. This change provided data for SO 2 

# , NO x 

# , and NH 3 

# not included in AR's inventory, but removed emissions from two counties (05017 and 05125) that had emissions in AR’s inventory.
Prescribed Burning for Forest Management (SCC 2810015000)
The Base A inventory contai ned VOC, CO, PM10-PRI, and PM25-PRI emissions for this category. At AR’s request, AR’s state inventory was removed from the Base B area source inventory and replaced with th e point source inventory deve loped by CENRAP. The CENRAPsponsored planned burning invent ory did not include any emissions for area sources. This change provided data for SO 2 

# , NO x 

# , and NH 3 

# not included in AR's inventory
Prescribed Burning of Rangeland (SCC 2810020000)
The CENRAP-sponsored planned burning inventor y contains point source emissions for VOC, CO, SO 2 

# , NO x 

# , NH 3 

# , PM10-PRI, and PM25-PRI for 17 countie s. This inventory was added to the Base B point source inventory.

Wildfires (SCC 2810001000)

The Base A inventor y contained VOC, NO x 

# , CO, PM10-PRI, and PM25-PRI emissions provided by AR, and NH 3 

# emissions estimated using a separate methodology based on the Carnegie Mellon University (CMU) Mode l (Version 6.1) defaults. AR decided to remove the NH 3 

# emissions from the area source inventory since the NH 3 

# emissions were not based on their state methodology.

b. Minnesota
MN provided an area source inventory on June 3, 2005. This inventory was used to update the Base A inventory for records where there was a match on the data key between the Base A inventory and MN’s June 3 file.

# 36 In addition, for the Base A modeling effort, the Midwest RPO point source inventory for wildfires (SCC 2810001000) and agricultural fi eld burning (SCC 2801500000) was to be used for MN, and, therefore, the area source emissions data for these two categories were removed. However, it was learned that the Midwest RPO point source inventory was not being used for modeling so the 2002 area source wildfire a nd agricultural field burning inventories were restored to the Base B inventory. The wildfi re inventory included in the Base B area source inventory originates from the 2002 NEI. The agri cultural field burning i nventory included in the Base B area source inventory originates fr om the CENRAP-sponsored planned burning inventory.

c. Texas
TX provided comments on the draft 2002 NEI and re quested that this comment file be used to update the CENRAP inventory. The comment file was obtained from EPA. The comment file was compared to both the CENRAP Base A invent ory and the draft 2002 NEI. As a result, there were many issues identified for which TX provi ded clarification on how to resolve. The QA issues, comparison of the comments to the Base A inventory and the NEI, and TX’s directions for resolving the QA issues are provided is se veral spreadsheets in the Excel workbook file (named TX_QA_Report_071405.xls) provi ded with this report. Af ter receiving TX’s direction for resolving the QA issues, the submittal flags in the comments file were adjusted in order to apply the comments to the CENRAP’s Base A i nventory. The following provides a summary of the effects of TX’s comments on the area source inventory:

• TX’s comments file requested that the categories for unpaved roads (SCC 2296000000) and human perspiration (SCC 2810010000) be removed from the Base A inventory. However, since all of the other states include emissions for these categories, TX agreed that the categories s hould be kept in th e inventory so these categories were removed from TX’s commen ts file. The exception is that the area source inventory contained CO and VOC em issions for human perspiration for three counties that originated from the 1999 NEI. The NH 3 

# emissions for human perspiration are from the CENRAP-sponsored inventory and occur in all of TX’s 254 counties. Therefore, per TX’s request, the CO and VOC emissions were removed from the three counties.

• TX provided emissions for Mobile Sources : Highway Vehicles - Diesel : All HDDV including Buses (use subdivisions -071 thru -075 if possible) : Total: All Road Types (SCC 2230070000) that were not in the Base A inventory. The emissions for this category were added to the Base B inventory. It is not clear if the emissions for this category represent idling emissi ons or not. If they repr esent idiling emissions, these emissions are not accounted for in the nonr oad inventory, thus, there would be no double counting of emissions.

• For the Base A inventory, daily PM emi ssions were excluded from the area source inventory because of many PM consistency issues with the daily emissions. TX provided revisions to the daily emissions ; however, after adding the daily emissions to the CENRAP inventory, many PM consiste ncy issues were iden tified. In addition,

# 37 for several categories it was discovered th at TX revised the annual and/or daily filterable emissions but not the primary emissions resulting in the primary emissions being less than the filterable emissions. A separate Excel wor kbook file is provided with this report that details the issu es identified and explains how TX’s PM emissions were adjusted to correct for inconsistencies in the reporting of PM emissions.
d. EI and Modeling Workgroup Comments
The EI and Modeling Workgroups requested th e following revisions to the area source inventory:

Natural Sources of NH 3 

# Emissions (SCCs starting with 27014xxxxx)
To provide consistent source category coverage across the CENRAP states for natural sources of NH 3 

# , the emissions in the CENRAP-sponsored inventory for natural sources of NH 3 

# were added to the Base B inventory for AR, MN, and MO. The monthly emissions were summed to calculate annual emissions that were also added to the inventory for these three states. The emissions for these categories were already in cluded in the area source inventory for the other CENRAP states.

Onroad NH 3 

# Emissions

Onroad NH 3 

# emissions for SCCs 2201001000 (Light Duty Gasoline Vehicles) and 2230001000 (Light Duty Diesel Vehicles) for IA, KS, and LA were removed from the area source inventory because the emissions for this category ar e included in CENRAP 's onroad inventory.
Stage II Refueling Emissions
CENRAP revised the onroad inventory to incl ude VOC emissions associated with Stage II refueling. Therefore, these emissions were re moved from the area source inventory to avoid double-counting of emissions. The Stage II emissi ons removed from the area source inventory were classified under the following SCCs:
SCC SCC Description 2501060100 Storage and Transport : Petroleum a nd Petroleum Product Storage : Gasoline Service Stations : Stage 2: Total 2501060101 Storage and Transport : Petroleum a nd Petroleum Product Storage : Gasoline Service Stations : Stage 2: Displacement Loss/Uncontrolled 2501060102 Storage and Transport : Petroleum a nd Petroleum Product Storage : Gasoline Service Stations : Stage 2: Displacement Loss/Controlled 2501060103 Storage and Transport : Petroleum a nd Petroleum Product Storage : Gasoline Service Stations : Stage 2: Spillage

# 38 PM Consistency Issues

It was discovered that the Oracl e scripts run on the Base A ar ea source inventory to identify cases where the PM10-PRI (PM25-PRI) emissi ons were less than the PM10-FIL (PM25-FIL) emissions did not work correctly. The scripts we re corrected and tested and run on the Base B inventory. As a result, for the agricultural tilling emissions (S CC 2801000003) originating from the CENRAP-sponsored inventory, it was learned that when the Base A inventory was updated with the revised CENRAP-sponsored agricultura l tilling inventory, the primary emissions got revised but the filterable emi ssions did not. Thus, in the Base B inventory, the filterable emissions have been revised to match the primary emissions.
6. QA Review of Final Inventory

Final QA checks were run on the revised data set to ensure that all corr ections provided by the S/L/T agencies were incorporated into the S/L/ T inventories and that there were no remaining QA issues that could be addres sed during the duration of the project. After exporting the inventory in Oracle to an Access database in NIF 3.0, the EPA’s QA program was run on the Access database and the QA output was reviewed to verify that all QA issues that could be addressed were resolved (EPA, 2004a).
The output file from the EPA’s QA program run on the area source inventory and the area miscellaneous source inventory is provided in an Access 2000 database along with the Access database containing the area and area miscellane ous inventory in NIF 3.0. The following lists the remaining QA issues that were not addr essed during the duration of this project:
Area Source Inventory
Range Errors: There are 1,408 r ecords in the EM table with emissions that exceed the maximum emissions in the QA program for the specified pollutant.
Area Miscellaneous Source Inventory
Range Errors: There is one EM record in MN for SCC 2701443000 with NH3 emissions that are significantly higher than the expected maximum emissions.
D. Nonroad Source Inventory Methods

1. Data Sources
CENRAP revised its Base A inventory for the NONROAD model categor ies to correct the oxygen content model inputs as well as the default values used for the sulf ur content of diesel. In addition, MN requested that the Midwest RP O Base J inventory be used in the revised CENRAP inventory. IA also re quested that the Midwest RPO Ba se J inventory be used for agricultural equipment categories instead of the revised CENRAP inventory. TX, who is using its own inventory for both the Base A and B inventories, added emissions for oil field equipment. The inventories for the cate gories not included in the NONROAD model (i.e., aircraft,

# 39 commercial marine vessels, and locomotives) re mained essentially unchanged from the Base A to the Base B inventory except for some revisions provided by TX.
The data files that the states provided for updati ng the Base A inventory were loaded into Oracle in NIF 3.0 into one data set. Then, the fo llowing updates were performed on the consolidated data set, if necessary:

• HAP records were removed since the inventor y will support region al haze, fine PM, and ozone modeling.

• Pollutant codes were corrected to make them NIF 3.0 compliant (e.g., update PMPRI pollutant code to PM-PRI). Additi onally, other codes were identified for remediation on a case-by-case basis.

• Records with a submittal flag indicating de letions (submittal_flag = ‘D’ or ‘RD’) were removed from the inventory.

• Null values in the tribal code field were upda ted to ‘000’ since this field is a part of the data key that defines records as unique in all eight NIF tables.

• Added and populated the NIF plus fields listed in the prev ious discussion for the area source inventory.

• The CENRAP-sponsored inventory did not co ntain S/L agency contact information in the TR table. Therefore, the TR table was updated to include the contact information that S/L agencies provide d in their area source inventories.

2. QA Review

QA review was conducted on the inventories in accordance with the QA procedures specified in the QAPP for this project (CENRAP, 2005b). Th e following discusses the QA checks that were completed during preparation of the consolidated data set.
a. County and SCC Coverage
The county coverage in the state inventories appeared to be reas onable for all states. The SCC coverage was difficult to evaluate simply by s howing a count of the number of SCCs by state. The EI and Modeling Workgroups reviewed summ aries comparing the Base B to the Base A inventory.
b. Pollutant Coverage
The pollutant coverage in the S/L/T inventories was complete for all pollutants after incorporating S/L comments.

# 40 c. Additional QA for the CENRAP Nonroad Source Inventory
The QA procedures discussed previously for th e S/L/T area source inventories were applied to the nonroad inventory.
3. Responses from S/L/T Agencies
The S/L/T agencies provided responses to ques tions about their data. The agencies or the Workgroups then provided direc tion for correcting the issues either by telephone or by e-mail.
4. Gap Filling and Augmentation
CENRAP-sponsored inventory data were added to the inventories as reque sted either by the S/L agencies or by the EI and Modeling Workgroups.

5. Revisions to Address Comments
The following discusses the revisions ma de to the Base A nonroad inventory:

a. Minnesota
For the NONROAD model categories, MN elected to use the Base J inventory prepared by the Midwest RPO. This inventory includes mont hly emissions. The monthly emissions were summed to calculate annual emissions, and reco rds were added to the inventory to hold the annual emissions for supporting the developmen t of emission summaries. The monthly emissions are used in the SMOKE IDA files for modeling.
The Midwest RPO Base J NONROAD model inventory was prepared by the state of WI. As a result, MN requested that the contact information for WI be listed in the TR table for MN.

b. Iowa
IA elected to use the CENRAP-sponsored inventor y for all of the nonroad categories except for the following agricultural equipment categories:
SCC SCC Description 22600050xx Off-highway Vehicle Gasoline, 2-Stro ke : Agricultural Equipment (2 SCCs); 22650050xx Off-highway Vehicle Gasoline, 4-Stro ke : Agricultural Equipment (11 SCCs); 22670050xx LPG : Agricultural Equipment (3 SCCs); 22680050xx CNG : Agricultural Equipment (3 SCCs); and 22700050xx Off-highway Vehicle Diesel : Agricultural Equipment (11 SCCs).
For the agricultural equipment categories, IA el ected to use the Midwes t RPO Base J inventory because this inventory provided improvements to the temporal allocation of emissions for the agricultural sector. The Base J inventory includes monthly em issions. The monthly emissions were summed to calculate annual emissions, and re cords were added to the inventory to hold the

# 41 annual emissions for supporting the developm ent of emission summaries. The monthly emissions are used in the SMOKE IDA files for modeling.

c. Texas
Oil Field Equipment Emissions
TX provided annual and daily emissions for CO, CO 2 

# , NO x 

# , VOC, SO 2 

# , PM10-FIL, and PM25- FIL for the following oil field equipment categories:
SCC SCC Description 2265010010 Off-highway Vehicle Gasoline, 4-Stroke : Industrial Equipment : Other Oil Field Equipment; 2268010010 CNG : Industrial Equipment : Other Oil Field Equipment; and 2270010010 Off-highway Vehicle Diesel : Indus trial Equipment : Other Oil Field Equipment

These emissions were added to the Base B i nventory. However, primary PM emissions are needed for the inventory. TX provided authoriz ation to change the pollutant codes from PM10- FIL to PM10-PRI and PM25-FIL to PM25-PRI.

Commercial Marine Vessels (SCC 2280000000)
TX provided revisions to the NH 3 

# emissions for commercial marine vessels for 17 counties and the inventory was updated with the revised emissions.

Railroad Locomotive Emissions (SCC 2285000000)

The Base A inventor y did not contain NH 3 

# emissions for this category in TX. TX provided the NH 3 

# emissions that were added to the Base B inventory.
d. EI and Modeling Workgroup Comments
Correction for Double Counting of Emissions in Lancaster County, Nebraska
Lancaster County provided its own nonr oad inventory for SCC 2260000000 (Off-highway Vehicle Gasoline, 2-Stroke : 2-Stroke Gasoline except Rail and Marine: All). In the Base A inventory, the CENRAP-sponsored inventory provi ded emissions for the more detailed SCCs and were included in the Base A inventory. Af ter reviewing the data and consulting with the local agency, the Workgroups decided to rem ove the CENRAP-sponsored inventory for SCCs starting with 226 in Lancaster County to remove double-counting of emissions.
Revisions to the CENRAP-Sponsored Inventory
For the categories included in the NONROAD model, all of the states elected to use the CENRAP-sponsored inventory in the Base B inventory except for MN and TX; IA for

# 42 agricultural equipment; and Lancas ter County, NE for 2-stroke gasoline vehicles. The following discusses the changes made to the CENRAP-sponsored inventory.
Revisions to Oxygen Content
The CENRAP-sponsored inventory for the NONROAD model categories was updated during March 2005 to correct the fuel oxyge nate content from decimal frac tion to percentage values. As a result, the NONROAD model inventory for the states that elected to use the CENRAPsponsored inventory was replaced with the new inventory.
Revisions to Diesel Sulfur Content
The input values used for the sulfur content of diesel fuel used in the revised CENRAP NONROAD model inventory were determined to be too low and the Workgroups decided to revise the input values for th is parameter to be based on the default values used by the NONROAD model. The following explains the methods applied to adjust the SO 2 

# , PM10-PRI, and PM25-PRI emissions in the CENRAP-sponsor ed inventory based on adjustments to the sulfur content in diesel fuel.

The SO 2 

# emissions were adjusted by using the ratio of the new versus the original diesel sulfur content values, since the relationship of SO 2 

# to diesel fuel sulfur levels is linear. However, for PM10-PRI and PM25-PRI emissions, the adjustment is not a linear relationship. To estimate the impact of higher diesel fuel sulfur levels on PM10-PRI and PM25-PRI emissions for each state, national runs of the NONROAD model were perfor med using the original and new diesel fuel sulfur input values for each state.
Table 8 provides the original dies el fuel sulfur content values for seven of the CENRAP states. The NONROAD inventories for Minnesota and Texa s and the agricultural equipment categories for IA were not revised because these States based their nonroad inventories on model runs that include the NONROAD model default sulfur values. The new diesel sulfur values are based on the NONROAD model default values. For di esel recreational ma rine engines (SCC 2282020005 and 2282020010), the NONROAD model uses a diesel sulfur content of 2,765 parts per million (ppm). For all other land-based diesel equi pment, NONROAD incorporates a default diesel sulfur content of 2,457 ppm. Table 8. Original Diesel Fuel Content

State Original DIESEL SULFUR content, ppm KS 330.0 AR 360.0 IA 360.0 NE 360.0 OK 360.0 LA 380.0 MO 390.0

# 43 National NONROAD model runs were performed usi ng the four unique sulfur levels in Table 8 (i.e., 330, 360, 380, and 390), and then two nati onal NONROAD runs were performed using the default diesel fuel sulfur content values. The re sults of these runs were used to develop statespecific SCC-level ratios based on the resulti ng PM10-PRI and PM25-PRI emissions. The SCCs to which these ratios were applied to adjust emissions are shown in Table 9.
6. QA Review of Final Inventory

Final QA checks were run on the revised data set to ensure that all corr ections provided by the S/L/T agencies were incorporated into the S/L/ T inventories and that there were no remaining QA issues that could be addres sed during the duration of the project. After exporting the inventory in Oracle to an Access database in NIF 3.0, the EPA’s QA program was run on the Access database and the QA output was reviewed to verify that all QA issues that could be addressed were resolved. The QA output is pr ovided in an Access 2000 database along with the Access database containing the inventory in NIF 3.0.
The following lists the remaining QA issues that were not addressed during the duration of this project:
Range Errors: There are 230 r ecords in the EM table with emissions that exceed the maximum emissions in the QA program for the specified pollutant.
Lookup Errors: There are 106,472 reco rds in the EM table with CO 2 

# emissions that caused this error. CO 2 

# is not included in the reference tabl e for valid NIF 3.0 pollutant codes. At the request of CENRAP, CO 2 

# emissions were kept in the inventory.
E. EGU 2018 Projection Year Inventory

1. Introduction

Pechan received from the Midwest RPO the 2018 IP M scenario file and ex tracted the data for each of the nine CENRAP states to post-proc ess. Pechan post-processed the 2018 Integrated Planning Model (IPM) scenario data to create the mass emissions inventory for the SMOKE/IDA files. The post-processing procedure incl udes estimating emissions for CO, VOC, NH 3 

# , PM10- PRI, PM10-FIL, PM25-PRI, PM25-FIL, and PM -CON. Emissions for 21 temporal-pollutant combinations are estimated since there are seve n pollutants and three temporal periods (summer season, winter season, July da y). Note that annual SO 2 

# and annual, summer season, and July day NO x 

# emission values are provided in the initial IP M scenario file. Firs t, annual emission are estimated by applying an SCC-based pollutant-spe cific uncontrolled emission factor (that may include sulfur and/or ash content factor) to fu el quantity (that is obtained from the annual heat input provided in the IPM run and default fuel-based heat contents), control removal efficiency, and a units conversion factor.

# 47 To obtain the needed temporal emissions, summer season emissions are estimated by multiplying the annual emissions by a ratio of the summer season to annual heat input; winter season emissions are estimated by subtracting the summ er season emissions from the annual emissions; and summer day emissions are estimated by multip lying the annual emissions by a ratio of the July day to annual heat input.
Table 10 presents the CO, VOC, NH 3 

# , PM10-FIL, and PM25-FIL emission factors by SCC. Table 11 presents the PM-CON emission fact ors by SCC. For PM10-FIL and PM25-FIL, control efficiencies (that are obtained usi ng an EPA-approved method) are applied to the uncontrolled emissions. PM-CON is estimated usi ng heat input (included in the IPM run) and emissions factors. PM10-PRI (and PM25-PR I) are obtained by summing PM-CON and PM10- FIL (PM-CON and PM25-FIL) emissions.
The post-processing methodology also includes the following steps:
Step 1: Adding data for all units.
SCCs were assigned for all units; unit/fuel/firing/bottom type data were used for existing units’ assignments, while only unit and fuel type were used for generic units’ assignments. Latitudelongitude coordinates were assigned, first using th e EPA-provided data files, secondly using the September 17, 2004 Pechan in-house latitude-longitude file, and lastly using county centroids. These data were only used when the data we re not provided in the 2002 NIF files. Stack parameters were attached, first using the EPA- provided data files, s econdly using a March 9, 2004 Pechan in-house stack parameter file base d on previous EIA-767 data , and lastly using an EPA June 2003 SCC-based default stack parameter file. These data were only used when the data were not provided in the 2002 NIF files. Plant ID (within State and county), point ID, process ID, and stack ID were th en attached, first using the EPA- provided data files, or secondly using Pechan-generated defaults: the point ID is assigned the value of the given boiler ID preceded by ‘#’, unless the boiler ID has a length of six [the length for the point ID], in which case the left-most character is replaced with ‘#’); and the default Pechan process ID is ‘01’. Default stack IDs within a plant are assigned fo r each unique stack height-diameter combination; the default Pechan stack ID is of the form ‘4N’ . The process ID and stack ID default data were only used when the data were not provided.

Note that PM10-PRI = PM10-FIL + PM-CON and PM25-PRI = PM25-FIL + PM-CON.

# 51 Step 2: Siting generic units usi ng an EPA-approved electronic method.
Generic aggregates, which consist of IPM-designated “planned/committed” units as well as “new” units produced by the IPM model are transfor med into units similar to the existing units in terms of the available data. The generic aggregat es are split into smalle r generic units based on their unit types and capacity, are provided a du mmy ORIS unique plant and boiler ID, and are given a county FIPS code based on an algorith m that sites each generic by assigning a sister plant that is in a county based on its attainment/nonattainment status . Within a state, plants (in county then ORIS plant code order) in attainment counties are used first as sister sites to generic units, followed by plants in PM nonattainment counties (as of January 2004), followed by plants in 8-hour ozone nonattainment counties (as of April 2004).
Step 3: Deriving defaults using the same methodology previously approved by the Midwest RPO and Visibility Improvement State and Trib al Association of the Southeast (VISTAS).
Additional data were required for estimati ng VOC, CO, PM10-FIL, PM25-FIL, PM-CON, and NH 3 

# emissions for all units. Thus, ash and su lfur contents were assigned by first using 2002 EIA-767 values for existing units or SCC-based defaults; PM10-FIL and PM25-FIL efficiencies were obtained from the 2002 EGU NEI that we re based on 2002 EIA-767 control data and the PM Calculator program (a default of 99.2 percent is used for coal units if necessary); fuel use was back calculated from the given heat input and a default SCC-based heat content; and emission factors were obtained from an EPA- approved October 7, 2004 Pechan emission factor file based on AP-42 emission factors. Note th at this updated file is not the one used for estimating emissions for previous EPA post-processed IPM files.
Step 4: Adding in S/L agency emissions inventory identifiers from the updated CENRAP crosswalk.
The previous crosswalk file was compared to th e Base B point source inventory and updated to as needed to ensure correct matching of the c odes in the IPM file to state IDs in the NIF 3.0 inventory file. The revised crosswalk file was then used to obtain st ate and county FIPS codes, plant IDs (within State a nd county), and point ID s. If the state and county FIPS codes, plant IDs and point IDs were in the 2002 NI F tables, then the process ID s and stack IDs were obtained from the NIF; otherwise, defaults, described above, were used.
Step 5: Transforming the data into annual SMOKE/IDA formatted text files for use by the modelers (see section II.E.4).

2. Data Sources
There are several data sources used during the post-processing procedure. These include the following:

$ Records from the nine CENRAP states from one Midwest RPO/VISTAS IPM “second round” parsed file, VISTASII_ PC_1f_FossilUnits_2018 (To Client).xls

# 52 $ The updated CENRAP crosswalk

$ Two EPA-approved emissions factor in -house file (Tables 10 and 11) for estimating annual VOC, CO, NH 3 

# , PM10-PRI, PM10-FIL, PM25-PRI, PM25- FIL, and PM-CON emissions

$ Other files used in previous IPM run post-processing (e.g., power plant latitudelongitude file, SCC assignment file, fuel-b ased heat content file, EIA-767-based stack parameters file, and EPA-appr oved default stack parameters file).

3. QA Review
Pechan performed QA of the inventory by extract ing the records for the CENRAP states from the 2018 IPM run and then checking to verify that all of the records ar e included in the CENRAP crosswalk and, if not, flagging them so that they are properly accounted for in the postprocessing. After the post-processing was complete d, and the data were tr ansformed into their proper format, Pechan compared the initial (f rom the IPM file) and final (from the SMOKE/IDA files) NO x 

# emission tons -- annual [summer plus wint er season], summer season, summer day -- and SO 2 

# annual [summer plus winter season] emissi on tons -- for each State and for the nine State total to ascertain that they did not change values; they did not.

4. SMOKE/IDA Files
The 2018 inventory was formatted as SMOKE/IDA summ er and winter files. The file structures are delineated in Tables 12 and 13.
5. Emissions Summary
Table 14 provides a summary of the summer season, summer day, and winter season emissions calculated for the 2018 EGU inventory an d included in the SMOKE IDA files.

# 65 III. SUMMARIES OF EMISSIONS INVE NTORIES FOR THE CENRAP REGION
Summaries of emissions were prepared from the emission inventory files for each sector and for all sectors combined. The summaries are provided in an Access 2000 database named “CENRAP Base B Emission Summaries_082205.mdb”. The same summaries are also provided in an Access 97 database named “CENRA P Base B Emission Summaries_082205_Acc97.mdb”.
Table 16 identifies and briefly de scribes the contents of the em issions summary tables included in the database. The nonroad source sector summaries include emissions for aircraft, commercial marine vessels, and locomotives as well as the emissions from the NONROAD model categories. The onroad summaries were prepared from the revised CENRAP-sponsored inventory for onroad sources. Tables 1G, 2C, 3C , 4C, and 5C include the data source code for the area, point, nonroad, and onroad sectors to a ssist in identifying the origin and year of emissions inventory data. The da ta source codes were defined pr eviously in Chapter II of this report.
The summaries in Appendix A of this report ar e taken from the emissions summary Table 1D. These summaries include natural sources NH 3 

# emissions and the biogenic wind erosion PM10- PRI and PM25-PRI emissions; thus, the emission totals in Appendix A match the totals in Chapter I, Table 1 of this report. Note, however , that the emissions for natural sources and wind erosion are excluded from Tables 2a through 2e of Chapter I.

A second Access 2000 database named “CENRA P Emission Summaries_Compare Base B to A_082205.mdb” provides summaries that compare the emissions in the Base B inventory to the Base A inventory. These summaries are provi ded for the “All Sector” Tables 1A through 1F series of summaries. These summaries are usef ul for identifying the st ates and sectors where annual emissions changed significantly as a re sult of the comments r eceived on the Base A inventories for all of the sectors. This database is also provided in Access 97 format (named “CENRAP Emission Summaries_Compare Base B to A_082205_Acc97.mdb”).

# 67 IV. METHODS FOR AREAS OUTSIDE OF THE CENRAP REGION
A. Data Sources and Augmentation Procedures
This task involved calculating fire emissions and source parameters given fuel, location, and time period information for the Province of Ontari o, Canada. CENRAP made the “raw” data for these fires available at http://www.cenrap.org/emission_document.asp . The names of the specific files made available include the following:

“Ontario Fires over 100 ha 1992- 2002 WFR.xls” “Ontario Fires over 100 ha 1992 -2002 WFR-EXPLAIN.xls”

The files contain data for 54 fires that occurred in Ontario during the year 2002. Information on the data code abbreviations, data definitions, a nd data units used in the raw data files was obtained from Mr. Rob Luik (Data Management Sp ecialist) at the Ontario Ministry of Natural Resources ( Rob.Luik@MNR. gov.on.ca ). Tables 17 and 18 provide de finitions of the fuel types and other data provided in the raw data files.

B. Development of BlueSky Inputs

Emissions for each fire were estimat ed using the Emission Production Model (EPM)/CONSUME within the BlueSky framework. To run EPM/CONSUME, the following information was needed for each fire:

• Fire identification code;

• Latitude and longitude of the fire;

• Start and end dates of the fire;

• Daily size of the fire; and

• Fuel loading information.

A fire identification code is needed to tr ack individual fires thr oughout the processing. The unique fire identification code was created for each fire by concatenating the FIRE_NUMBER and CUR_DIST fields of the original data. The fire identification code also contains the FIPS code of the fire; this information is not us ed by BlueSky but is needed by BlueSky2Inv, the utility program that converts the BlueSky outpu t to the SMOKE inventory format. The FIPS code 135000 was used for all fires with long itudes east of –90°, and FIPS code 135059 was used for fires west of –90°. These FIPS codes were used to ensure that the fires would be assigned the correct time zones in later SMOKE processing.
The DISC_DATE field (discovery date) was used as the start date for each fire. While the original data did provide start da tes earlier than the discovery da te for some fires, the discovery date was used for all fires for consistency. Similarly, the OUT_DATE field was used from the original data as the end date fo r each fire. Some of the date s provided in the original data included hourly information. In al l cases, the hourly information wa s not used leaving all data at a daily resolution.

# The total number of days each fire burned was de termined using the start and end date for each fire. For each fire, the size of the area bur ned each day was estimated. The original data included the final size of each fire which was used to determine the total area burned by each fire. Rather than introduce additional assumptions about the daily fire size, it was assumed that the area burned each day was constant over all days . Therefore, the total size of the fire was divided by the total days the fire burned to get an estimate of the daily fire size. The area burned by each fire was converted from hectares to acres as needed by EPM/CONSUME.
For each fire, fuel loading data must be provided to indicate the type of fuels available for burning so that the emissions can be estimated. Th e original data included fuel type information for each fire using the Canadian Forest Fi re Danger Rating System (CFFDRS) fuel types. Descriptions of each fuel type are available at http://fire.cfs.nrcan.gc. ca/research/environment/ cffdrs/fbpfuels_e.htm. Detailed fuel informa tion for these types could not be identified; therefore, the CFFDRS types were mapped to th e types used by the National Fire Danger Rating System (NFDRS). Information about these fuel type s is available at http://www.fs.fed.us/fire/planning/ nist/nfdr.htm. Table 19 shows how the CFFDRS fuel types in the original data were mapped to the NFDRS fuel types, and shows the total number of fires for each fuel type. Table 20 shows the default fu el loading factors included in BlueSky for each NFDRS fuel type.

# Three of the 54 fires in the raw data files did not have any latitude and longitude coordinates or any fuel type data. Therefore, the three fires were excluded from the inventory. The three fires combined accounted for less than 1 percent of th e total area burned by all 54 fires. The raw data files did not contain any fuel type data for two other fires. The coordinates provided for these two fires were matched with the BELD3 database to determine the dominant vegetation type at the location of each fire. In both cases, th e vegetation type was USGS conifer, which was mapped to NFDRS Type U (close d western long-needled pines).
All other inputs to EPM/CONSUME including mete orology-based parameters used the BlueSky defaults.
C. Development of SMOKE Inventory Files
After running BlueSky with the prepared i nputs, the SMOKE utility program “BlueSky2Inv” was used to convert the EPM/CONSUME output to the inventory files needed by SMOKE. Since the EPM/CONSUME output is daily, Blue Sky2Inv creates a PTHOUR file containing the daily emissions for each fire. The data includ ed in the PTHOUR file ar e daily values for the fire’s area (AREA), heat flux (HFLUX), PM 2.5 

# , PMC (calculated as PM 10 

# – PM 2.5 

# ), CO, and total organic gases (TOG) (calculated as methane + non-methane hydrocarbons).
BlueSky2Inv also creates an annua l IDA inventory file. This file does not contain any emissions data but serves as a master list of sources. Th e annual inventory also c ontains the latitude and longitude of each fire. For all s ources, BlueSky2Inv assigned the SCC 2810001000 (Miscellaneous Area Sources; Other Co mbustion; Forest Wildfires; Total).
Since BlueSky2Inv was developed for US invent ories; therefore, the “#COUNTRY” headers in both output inventories were changed to CANADA.
D. SMOKE Input Files
The draft inventory files were provided to CENRAP via email on July 19, 2005. The following files were delivered:

# 71 • ptinv.ontario_fires.2002.txt: annual fire event inventory in IDA format

• ptday.ontario_fires.2002.txt: daily fire emissions inventory

• monthly.ontario.2002.txt: a report file summarizes the emi ssions by fire and by month. This report could be used to build monthly or annual fire emissions inventories if needed.
E. Emissions Summary
Table 21 provides a summary of monthly emissi ons calculated for 2002 Ontario fires. Emissions were estimated for CO, PM 2.5 

# , coarse PM (PMC) and TOG. Note that the modeling framework selected for estimating emissions does not include factors for estimating NO x 

# , SO 2 

# , and NH 3
