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 (NH3) emissions inventories for point, area, and

nonroad sources for the Central Regional Air Planning Association (CENRAP) Regional

Planning Organization (RPO). The “Base A” 2002 inventory files completed during February

2005 were updated to incorporate comments provided 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 “Base 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 tribal jurisdictions of Arkansas, Iowa, Kansas,

Louisiana, Minnesota, Missouri, Nebraska, Oklahoma, and Texas. CENRAP (and other RPOs)

will use these inventories to support air quality 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 emissions and modeling inventories for point,

area, and nonroad sources of 2002 emissions for the CAPs and NH3 for the S/L/T

agencies included in the CENRAP region;

(2) Modeling inventory files containing 2018 projection year emissions for EGUs; and

(3) A modeling inventory for Ontario fires during 2002.

The mass emissions inventory files were prepared in the National Emissions Inventory (NEI)

Input Format Version 3.0 (NIF 3.0). The modeling inventory files were prepared in the

SMOKE/IDA format. The revisions to the Base A point, area, and nonroad 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 inventories. Therefore, there were no revisions to the

ancillary files containing the spatial, temporal, and speciation profile data.

The inventories include annual emissions for sulfur dioxide (SO2), oxides of nitrogen (NOx),

volatile organic compounds (VOC), carbon monoxide (CO), NH3, and particles with an

aerodynamic diameter less than or equal to a nominal 10 and 2.5 micrometers (i.e., primary PM10

and PM2.5). The inventories included summer day, 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 consistent set of daily emissions for all source

categories and pollutants. Therefore, daily 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 calculate daily emissions. If needed,

the daily emissions prepared by the agencies may 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-sponsored inventories; and

(4) Comments from CENRAP’s EI and Modeling Workgroups.

The United States (U.S.) Environmental Protection Agency’s (EPA’s) format and content QA

programs (and other QA checks not included in EPA’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 (QAPP) prepared for this project (CENRAP, 2005a;

CENRAP, 2005b). The EI Workgroup and S/L/T agencies reviewed the draft inventory files

after updating the inventories, and the files were updated to address their comments.

B. Summary of the 2002 Base Year Inventories

This section of the report provides a brief summary of the consolidated 2002 Base B inventories

for the CENRAP region. Table 1 shows total annual emissions for CAPs and NH3 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 NOx (35 percent) and SO2

(83 percent) emissions. Area sources account for the highest percentage of total VOC

(44 percent), primary PM10 (PM10-PRI (93 percent)), primary PM2.5 (PM25-PRI (81 percent)),

and NH3 (83.5 percent) emissions. Onroad sources account for the highest percentage of CO

(57 percent) emissions. Onroad sources account for 24.5 percent and nonroad sources account

for 17 percent of total VOC emissions. Onroad sources account for 33 percent and nonroad

sources account for 18.5 percent of total NOx emissions.

Table 2a shows total annual emissions by state and pollutant for all four 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, NOx, CO, SO2, PM10-PRI and PM25-

PRI, and NH3, respectively. The emissions in each table are sorted in descending order with the

highest emitting categories listed at the top of the table. The tables also show annual emissions

as a percentage of total emissions from all sectors, 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 inventories. The point source inventories are included

in the Base B inventory; however, the area source 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 and the area source emissions are summarized in

Table 2f (note that these area source emissions are not included in Tables 1, 2a, and 2b).

The nonroad Base B inventory includes carbon dioxide (CO2) emissions, the point source

inventory includes total primary and filterable particulate matter (PM-PRI/-FIL) emissions, and

the point and area source inventories include filterable PM10 (PM10-FIL), filterable PM2.5

(PM25-FIL), and condensible PM (PM-CON) emissions. The emissions for these pollutants

were carried in the mass emissions inventory files. However, these pollutants are not included in

the summaries since the emissions for these pollutants 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 emissions 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 geogenic and natural/biogenic sources) described in

Chapter III of this report.

C. Organization of the Report

In Chapter II of this report, section A provides an introduction to the chapter and sections B

through D present the data sources and methods applied 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 sources 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 region. Chapter IV presents the data sources

and methods applied to prepare SMOKE input files 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 work plan and methods document was prepared and

reviewed by the CENRAP EI and Modeling 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. However, during the duration of the project, the

Workgroups requested additional revisions to the Base A point, area, and nonroad inventories

after the draft work plan and methods document 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 and resource constraints, the draft work plan and

methods document was not revised to reflect this additional work.

II. REFINEMENT OF THE CRITERIA AIR POLLUTANT AND NH3 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-sponsored 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 update the Base A inventories, Pechan performed QA

review of the inventories to identify (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 support 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 inventory (see section II.B for

additional details).

After resolving the QA issues, the files were updated to revise or add data provided by the S/L/T

agencies. In addition, the CENRAP’s Base A NONROAD model inventory was revised to

correct input data for the oxygen content of fuels and the SO2 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 CENRAP 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 section discusses the augmentation procedures that

were applied to fill in missing data. These procedures 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 added to the inventories

after incorporating inventory 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 projection 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 number 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 facilities in the 2002 preliminary

NEI.

The inventories obtained from EPA are in Access 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 inventories into Oracle in NIF 3.0, the following updates were performed

on the consolidated data set, if necessary:

• 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). Additionally, 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 revise 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, Pechan 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 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 updated 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 Point (ER), Emission Process (EP), Emission

Period (PE), Emission (EM), and Control Equipment (CE) tables:

• Data Source Codes:

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 available; therefore, condensible

emissions were not estimated for these processes if an agency

provided filterable and not primary emissions for these processes.

AUG-Z PM Augmentation: automated fill-in of zero values where all PM

for a particular process is zero.

• Revision Date: This field indicates the month and year during which the last

revision was made to a record. For the Base B inventory, for new or updated

records, it is 0705.

• State Federal Information Processing Standard (FIPS): This field indicates the

state FIPS code of the submittal.

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

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

• Emission Ton Value: This field indicates the values of the emissions in tons.

This field was used to prepare summaries of emissions on a consistent

emission unit basis.

• Emission Type Period: This field indicates 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 replacement inventories (Arkansas, Leech Lake) were

reviewed for pollutant coverage and other potential issues. Arkansas’ Base A inventory included

emission data from the CENRAP-sponsored inventories 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 replacements 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 data 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 emission record, but was missing one or more of

the following (as appropriate for the Source 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 diagnosed as an error. If a S/L/T agency did not

provide corrections to these errors, the errors 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 were within 0.5-kilometers of the boundary of the

county in which the source was located. ERP records with coordinates located more than 0.5, 1,

2, 3, 5, 7, and 10 or more kilometers from their county boundary, and coordinates that mapped

outside of their state boundary were identified. Arkansas’ new point source inventory contained

what appeared to be new coordinates not included in its Base A inventory. 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 within 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 values specified in the EPA’s QA procedures, and

consistency checks (i.e., comparing calculated values against expected values). In many cases

errors were due to defaulted zeros, and submitting 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 procedure 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 types 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 efficiencies 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 records where 100 percent control was reported in the CE table, but

the emissions in the EM table were greater than zero and the rule effectiveness 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 effectiveness field or a default value of zero was assigned,

records with null or zero rule effectiveness values 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 the transmittal table, and to confirm that the end

date reported is greater than the start date reported. 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 identify potential errors associated with the

incorrect reporting of daily 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, this 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 additional types of daily

emissions.

• Multiple records coded at the process level (or SCC, in the case of area) with the same

start and end date, but different emission types. While not a true duplicate, this may

indicate an error or just an inclusion 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 questions about their data. When necessary, QA

issues were summarized in Excel spreadsheets and sent to the agencies and the EI and Modeling

Workgroups for review. The agencies or the Workgroups 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 missing pollutant data from data provided by the

S/L/T agencies in order to develop a complete 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 pollutants 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 (Version 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 Control Device Ratio table, the Emission Factors

table and Emission Factors Crosstab table discussed in Step 2. The PM Calculator ratio table can

be provided upon request – it contains all possible 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 files that detailed potential inconsistencies and

missing information in their PM pollutant inventory. Inconsistencies in PM pollutants include

the following:

• PM-PRI less than PM10-PRI, PM25-PRI, 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 other processes only PM10-FIL was provided.

S/L/T agencies were asked to review this information and provide corrections where possible. In

general, corrections (or general directions) were provided in the case of the potential

inconsistency issues. An example of a general 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 cases, the agency-provided specific process level

pollutant corrections. In general, if specific direction was not provided by the agency, priority

was given to the PM10 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 control device. This table is called the SCC Control

Device Ratios table. The table structure is shown in Table 5 which follows the discussion below.

This table was filled according to the following steps:

• Ratios (both condensible and noncondensible) were added from FIRE for SCCs

starting with 10* (external fuel combustion) 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 the 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. Condensible 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 devices 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. Condensible ratios were calculated from

uncontrolled FIRE emission factors based for 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 obtained from the PM Calculator. It was

assumed that the condensible component was zero.

Accompanying this document is a database containing the SCC Control Device Ratios table.

Additionally, the Emission Factors and Emission Factors Crosstab table (which are derived from

FIRE) are provided. The Emission Factors Crosstab table contains the ratios 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 developed using a standard input of 100 TONS of

uncontrolled PM-FIL emissions.

ratios were not found in FIRE for 10* and 20* these ratios were set to zero.

PM-CON/PM10-PRI Condensible ratios were calculate from FIRE if available for 10* and 20* SCCs. If condensible

ratios were not found in FIRE for 10* and 20* these ratios were set to zero.

PM-CON/PM25-FIL Condensible ratios were calculate from FIRE if available for 10* and 20* SCCs. If condensible

ratios were not found in FIRE for 10* and 20* these ratios were set to zero.

PM-CON/PM25-PRI Condensible ratios were calculate from FIRE if available for 10* and 20* SCCs. If condensible

ratios were not found in FIRE for 10* and 20* these ratios were set to zero.

PM-CON/PM-FIL Condensible ratios were calculate from FIRE if available for 10* and 20* SCCs. If condensible

ratios were not found in FIRE for 10* and 20* these ratios were set to zero.

PM-CON/PM-PRI Condensible ratios were calculate from FIRE if available for 10* and 20* SCCs. If condensible

ratios were not found in FIRE for 10* and 20* these ratios were set to zero.

3. Implementation of the QA Ratios

In order to calculate the additional 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 there was a conflict between the control devices

reported for the same process for PM pollutants (for example, a PM10-PRI is listed as controlled,

but PM-PRI did not have control information), the control device type was selected based on the

controlled pollutant.

In addition to the fields listed above, the crosstab included the PM emission amounts for the

particular process and a field that indicated whether those emissions 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_PRI, PM_FIL, PM10_PRI, PM10_FIL, PM25_PRI,

PM25_FIL, PM_CON fields. The _EXISTS field indicates whether the pollutant was provided

by the S/L/T agency. A zero indicates 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 agency 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 assumption was that for non 10* and 20* SCCs, the

condensible value was zero – that would lead to PM10-FIL = PM10-PRI and PM25-FIL =

PM25-PRI and PM-FIL = PM-PRI. Given that assumption, values for these pollutants were also

filled in. After this data insertion, a subset of the crosstab was created. This subset only

contained processes that required additional augmentation. The SCC control device type ratio

table described in step 2 was based on only those SCC and control device types that required

augmentation.

The next step was to fill in the missing information in this crosstab using the information found

in the SCC Control Device Ratio table.

In calculating PM complement pollutants, priority 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 PM10 where available, PM25 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 PM10 (FIL or PRI) where available, PM2.5 (FIL or PRI) where

available, and then PM (FIL or PRI) if PM10 or PM2.5 variations were not available. Where both

PM10 (FIL or PRI) and PM2.5 (FIL or PRI) variations were both available, the calculation for

PM-CON was generally driven from the PM10 number and the complements as necessary were

back calculated. Where a –PRI emission factor ratio was required and was 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 and 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, these PM-CON values were not added to the

inventory.

System Update Note

This field contains system codes related to the update queries

used to calculate the record.
22

The data source code field is used to identify records that are added to the inventory to complete

the set of PM10-PRI and PM25-PRI emissions 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 records that did not have any

coordinates in the S/L/T inventory, the following 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 and 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 location. 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 source NEI (EPA, 2004b). It has been determined

that the augmentation procedures in this document regarding SCC-specific ERP types and

temperatures are difficult to resolve. When this situation occurs, preference 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 defined as a stack source and the other as a fugitive

source. Therefore, the S/L/T-supplied ERP type 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 issues would be resolved through consultation with

the S/LT Agencies. Default augmentation procedures were developed and applied to resolve

control efficiency issues. In the event that control 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 inventory. Arkansas confirmed that they revised the

SCCs and emissions in this new inventory. Therefore, the previous Base A inventory was used

as a guide for correcting ER coordinates and stacks and other QA issues.

County 777 information was removed from the entire 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 numeric 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” were nulled out (44 records).

Material IO codes of “U” were 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 unit 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 per instruction from the state.

Note: The NH3 emissions in Arkansas’ new inventory decreased considerably from the

emissions in the Base A inventory. A comparison of the emissions was provided to Arkansas for

review and confirmation that the revised emissions are correct.

PE

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

Material IO codes of “U” were nulled out (6 records).

Nulled out throughput unit numerator where 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 longer 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 added 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 all 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 coordinates based on Base A inventory.

Stack augmentation and coordinate augmentation 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 and revisions to their SO2 emissions. These revisions were applied to

their submittal.

EM

Emission revisions were made to records where the 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 integrity, records in the comment file were added to

the ER, EU, EP, and PE tables. In addition, a correction was made to the start and end dates to

ensure that they all started with 2002, in some cases, 2003 was used.

c. Kansas

Kansas provided comments to the EPA; however, after an initial incorporation 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 inventory remained unchanged.

d. Minnesota

Minnesota submitted new information for municipal airport emissions as well as revisions to

their PM data.

ER

When inserting the new municipal airport emissions, 236 fugitive records were 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 information, it was determined that there were 13

duplicate records and one inconsistent ER-EU combination for NH3. The new information

submitted was selected over the previous information.

Minnesota included updates to their PM information. Where the PM values were new, they were

added to the inventory (after removing previously augmented data). Where the PM values were

revisions, the records were revised (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 through consultation with the 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 part of the emission numeric value 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 were still several comparative problems. Upon

review, it was determined that a number of these 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 records, 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 Agricultural Field Burning

For the Base A modeling effort, the Midwest RPO’s point source inventory 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 Midwest RPO provided the inventory in point source

SMOKE input format). However, it was learned 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 point source inventory and restored 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 for a fugitive ERP. This was defaulted to the

stated default fugitive ERP values.

Leech Lake did not provide exit velocity and exit flow information for two ERPs. These were

defaulted according to the methods document.

EM

Leech Lake did not provide PM25-PRI emissions. For the point source SCCs, PM25-PRI

emissions were estimated based on the PM augmentation methods. For the single area source

SCC for prescribed burning, the PM25-PRI emissions were estimated by dividing the PM10-PRI

emissions by a ratio of 1.14. This ratio is the lower of two values (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 Cloquet 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 significantly 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 there were no common ERP coordinates or other
27

information to indicate duplication of data. Thus, the airport emissions and prescribed burning

emissions in Leech Lake’s inventory were included in the Base B point source inventory.

f. Missouri

Missouri provided a complete replacement inventory; however, upon further discussion and

agreement with Missouri, the replacement inventory 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 table were updated based on the crosswalk entitled

CENRAPxwalk051005.mdb with modifications made for some emission unit identifier changes

made by Arkansas. The revised crosswalk including 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 data, 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 resolved 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 revised point source inventory data set to ensure that all

corrections provided by the S/L/T agencies were incorporated into the Base B inventory and that

there were no remaining QA issues that could be addressed during 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 was 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 during the duration of this

project (listed by table):

CE

Primary device type codes are null for the confined animal feeding operations and planned

burning (forest and rangeland). The data originates from the CENRAP-sponsored inventories for

these categories. Missouri also has null primary device types for the majority of the CE records

it provided for NH3 emissions.

EM
28

The EPA QA program indicated that some emissions were outside the expected range. While

this is a guideline and not a specific error, this listing could 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 operating 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 supplementary coordinate reference information

(Horizontal data measure, horizontal data accuracy, horizontal collection method code).

Several records indicate coordinates outside of county boundaries – the reasons why this may

occur were explained in the coordinate augmentation section earlier in this document.

Several records also indicate stack parameters 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 which 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 (particularly the NH3 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 these; however, these inventories are the source of the majority of

these errors.

NAICs codes are missing or invalid on some records (470), primarily in Nebraska and Oklahoma

which did not provide comments during this time. 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 comments for updating the Base A inventory. AR and

MN provided comments on the Base A inventory, 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 inventory. In addition, the EI and Modeling

Workgroups provided several comments resulting in revisions to the area source inventory.

Documentation of the revisions made to the Base A inventory are provided in section II.C.5.

The data files that the states provided for updating the Base A inventory were loaded into Oracle

in NIF 3.0 into one data set. Then, the following updates were performed on the consolidated

data set, if necessary:

• 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). Additionally, 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 revise 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 flag 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 updated 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 added to the EP, PE, EM, and CE tables:

• Data Source Codes:

For the area and nonroad inventory data, the data source codes were based on the following 9-

character format:

[Data Origin]-[Year]-[Grown/Not Grown/Carried Forward]-[PM Augmentation Code]
30

Code Field Length

Data Origin 1

Year 3 (including leading hyphen)

Grown/Not Grown/Carried Forward 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 Inventory 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 inventory were grown to represent 2002

emissions.

-F Used when emissions in a pre-2002 inventory were carried forward and

included in the 2002 inventory without 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 were replaced with 2002 S/L/T data.

PM Augmentation Codes

-PA PM Augmented Emissions: Record for PM10/PM2.5 emissions that were

updated or added using ad-hoc updates.

-PC PM Augmented Emissions: Record added for PM10/PM2.5 emissions estimated

using the PM Calculator.

-PR PM Augmented Emissions: Record added for PM10/PM2.5 emissions estimated

using ratios of PM10-to-PM or PM2.5-to-PM10. If PM10 and PM2.5 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 factor 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 NOx emission factor by the NOx 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 source inventories in accordance with the QA

procedures specified in the QAPP for this project (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 showing a count of the number of SCCs by state.

The EI and Modeling Workgroups reviewed summaries 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 PM10

and PM2.5. Diagnosis and resolution of PM10 and PM2.5 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 diagnosed as an error. If a S/L/T agency did not

provide corrections to these errors, the errors were corrected/filled according to an augmentation

procedure explained in sections 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 PM10, PM2.5, and PM-CON

pollutants.

TX’s area source inventory had many records that 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 provide daily primary emissions. TX was consulted on how to

resolve the PM issues and TX provided directions 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 with a null or uncontrolled code of 000 but with

control efficiency data).

QA review of control efficiency data involved diagnosis of two types 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 efficiencies 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 value 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 records where 100 percent control was reported in the CE table, but

the emissions in the EM table were greater than zero and the rule effectiveness 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 effectiveness field or a default value of zero was assigned,

records with null or zero rule effectiveness values were included where the CE was 100 percent

and emissions were greater than zero. For records that met these criteria, Pechan consulted with

the S/L/T agency to determine if corrections were needed to any of the fields.

Start and End Date Checks

The year in the start and end date values in the PE and EM tables were reviewed to confirm

consistency with the inventory year in the transmittal 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 reviewed 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 additional 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 additional types of daily emissions.
34

• Any “DAILY” type record that was missing its associated “ANNUAL” record was

flagged for review.

• Any “DAILY” type record that was greater than its associated “ANNUAL” record

was flagged for review.

3. Responses from S/L/T Agencies

The S/L/T agencies provided responses to questions about their data. The agencies or the

Workgroups then provided direction for correcting the issues either by telephone or by e-mail.

For AR and TX, QA issues were summarized in Excel 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 agency responses. The first spreadsheet in each QA

Summary Report defines the remaining spreadsheets in the Excel Workbook file and provides

instructions for communicating revisions.

Table 7. QA Summary Reports for S/L/T Area Source Inventories

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 requested 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

NH3 Emissions

To be consistent with the NH3 categories included for the other CENRAP states, the following

NH3 categories in the CENRAP-sponsored area source inventory were added to the 2002 Base B

inventory for AR:

SCC SCC Description

2630020000 Wastewater Treatment : Public 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 contained VOC, CO, PM10-PRI, and PM25-PRI emissions provided by

AR. At AR’s request, AR’s state inventory was replaced with the CENRAP-sponsored

inventory. The activity data for the CENRAP-sponsored inventory were developed by surveying

local agricultural extension service agents which are believed to provide better spatial and

temporal resolution of agricultural field burning activity than the methods that were used for

AR’s inventory. This change provided data for SO2, NOx, and NH3 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 contained 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 the point source inventory developed by CENRAP. The CENRAPsponsored planned burning inventory did not include any emissions for area sources. This

change provided data for SO2, NOx, and NH3 not included in AR's inventory

Prescribed Burning of Rangeland (SCC 2810020000)

The CENRAP-sponsored planned burning inventory contains point source emissions for VOC,

CO, SO2, NOx, NH3, PM10-PRI, and PM25-PRI for 17 counties. This inventory was added to

the Base B point source inventory.

Wildfires (SCC 2810001000)

The Base A inventory contained VOC, NOx, CO, PM10-PRI, and PM25-PRI emissions provided

by AR, and NH3 emissions estimated using a separate methodology based on the Carnegie

Mellon University (CMU) Model (Version 6.1) defaults. AR decided to remove the NH3

emissions from the area source inventory since the NH3 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 field 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 and agricultural field burning inventories were

restored to the Base B inventory. The wildfire inventory included in the Base B area source

inventory originates from the 2002 NEI. The agricultural field burning inventory included in the

Base B area source inventory originates from the CENRAP-sponsored planned burning

inventory.

c. Texas

TX provided comments on the draft 2002 NEI and requested 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 inventory and the draft 2002 NEI. As a result, there

were many issues identified for which TX provided 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 several spreadsheets in the Excel workbook file

(named TX_QA_Report_071405.xls) provided with this report. After 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 inventory. 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 should be kept in the inventory so these

categories were removed from TX’s comments file. The exception is that the area

source inventory contained CO and VOC emissions for human perspiration for three

counties that originated from the 1999 NEI. The NH3 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 emissions or not. If they represent idiling emissions, these

emissions are not accounted for in the nonroad inventory, thus, there would be no

double counting of emissions.

• For the Base A inventory, daily PM emissions 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 consistency issues were identified. In addition,
37

for several categories it was discovered that 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 workbook file is provided

with this report that details the issues 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 the following revisions to the area source

inventory:

Natural Sources of NH3 Emissions (SCCs starting with 27014xxxxx)

To provide consistent source category coverage across the CENRAP states for natural sources of

NH3, the emissions in the CENRAP-sponsored inventory for natural sources of NH3 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 included in the area source inventory for the other

CENRAP states.

Onroad NH3 Emissions

Onroad NH3 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 are included in CENRAP's onroad inventory.

Stage II Refueling Emissions

CENRAP revised the onroad inventory to include VOC emissions associated with Stage II

refueling. Therefore, these emissions were removed from the area source inventory to avoid

double-counting of emissions. The Stage II emissions removed from the area source inventory

were classified under the following SCCs:

SCC SCC Description

2501060100 Storage and Transport : Petroleum and Petroleum Product Storage : Gasoline

Service Stations : Stage 2: Total

2501060101 Storage and Transport : Petroleum and Petroleum Product Storage : Gasoline

Service Stations : Stage 2: Displacement Loss/Uncontrolled

2501060102 Storage and Transport : Petroleum and Petroleum Product Storage : Gasoline

Service Stations : Stage 2: Displacement Loss/Controlled

2501060103 Storage and Transport : Petroleum and Petroleum Product Storage : Gasoline

Service Stations : Stage 2: Spillage
38

PM Consistency Issues

It was discovered that the Oracle scripts run on the Base A area source inventory to identify

cases where the PM10-PRI (PM25-PRI) emissions were less than the PM10-FIL (PM25-FIL)

emissions did not work correctly. The scripts were corrected and tested and run on the Base B

inventory. As a result, for the agricultural tilling emissions (SCC 2801000003) originating from

the CENRAP-sponsored inventory, it was learned that when the Base A inventory was updated

with the revised CENRAP-sponsored agricultural tilling inventory, the primary emissions got

revised but the filterable emissions 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 corrections 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 addressed 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 miscellaneous inventory in NIF 3.0. The following lists

the remaining QA issues that were not addressed during the duration of this project:

Area Source Inventory

Range Errors: There are 1,408 records 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 categories to correct the

oxygen content model inputs as well as the default values used for the sulfur content of diesel.

In addition, MN requested that the Midwest RPO Base J inventory be used in the revised

CENRAP inventory. IA also requested that the Midwest RPO Base 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 categories not included in the NONROAD model (i.e., aircraft,
39

commercial marine vessels, and locomotives) remained 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 updating the Base A inventory were loaded into Oracle

in NIF 3.0 into one data set. Then, the following updates were performed on the consolidated

data set, if necessary:

• 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). Additionally, other codes were identified for

remediation on a case-by-case basis.

• Records with a submittal flag indicating deletions (submittal_flag = ‘D’ or ‘RD’)

were removed from the inventory.

• Null values in the tribal code field were updated 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 previous discussion for the area

source inventory.

• The CENRAP-sponsored inventory did not contain S/L agency contact information

in the TR table. Therefore, the TR table was updated to include the contact

information that S/L agencies provided 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). The 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 reasonable for all states. The SCC

coverage was difficult to evaluate simply by showing a count of the number of SCCs by state.

The EI and Modeling Workgroups reviewed summaries 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 the 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 questions about their data. The agencies or the

Workgroups then provided direction 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 requested either by the S/L

agencies or by the EI and Modeling Workgroups.

5. Revisions to Address Comments

The following discusses the revisions made 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 monthly emissions. The monthly emissions were

summed to calculate annual emissions, and records were added to the inventory to hold the

annual emissions for supporting the development 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 inventory for all of the nonroad categories except for

the following agricultural equipment categories:

SCC SCC Description

22600050xx Off-highway Vehicle Gasoline, 2-Stroke : Agricultural Equipment (2 SCCs);

22650050xx Off-highway Vehicle Gasoline, 4-Stroke : 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 elected to use the Midwest 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 emissions. The monthly emissions

were summed to calculate annual emissions, and records were added to the inventory to hold the
41

annual emissions for supporting the development 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, CO2, NOx, VOC, SO2, 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 : Industrial Equipment : Other Oil Field 

Equipment

These emissions were added to the Base B inventory. However, primary PM emissions are

needed for the inventory. TX provided authorization 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 NH3 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 inventory did not contain NH3 emissions for this category in TX. TX provided the

NH3 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 nonroad 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 provided emissions for the more detailed SCCs

and were included in the Base A inventory. After reviewing the data and consulting with the

local agency, the Workgroups decided to remove 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 Lancaster 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 oxygenate content from decimal fraction 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 this parameter to be based on the default values used by the

NONROAD model. The following explains the methods applied to adjust the SO2, PM10-PRI,

and PM25-PRI emissions in the CENRAP-sponsored inventory based on adjustments to the

sulfur content in diesel fuel.

The SO2 emissions were adjusted by using the ratio of the new versus the original diesel sulfur

content values, since the relationship of SO2 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 performed using the original and new diesel fuel

sulfur input values for each state.

Table 8 provides the original diesel fuel sulfur content values for seven of the CENRAP states.

The NONROAD inventories for Minnesota and Texas 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 diesel recreational marine 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 equipment, NONROAD incorporates a default diesel

sulfur content of 2,457 ppm.

Table 8. Original Diesel Fuel Content

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 using the four unique sulfur levels in Table 8

(i.e., 330, 360, 380, and 390), and then two national NONROAD runs were performed using the

default diesel fuel sulfur content values. The results of these runs were used to develop statespecific SCC-level ratios based on the resulting 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 corrections 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 addressed 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 provided 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 records 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 records in the EM table with CO2 emissions that caused

this error. CO2 is not included in the reference table for valid NIF 3.0 pollutant codes. At

the request of CENRAP, CO2 emissions were kept in the inventory.

E. EGU 2018 Projection Year Inventory

1. Introduction

Pechan received from the Midwest RPO the 2018 IPM scenario file and extracted the data for

each of the nine CENRAP states to post-process. 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 includes estimating emissions for CO, VOC, NH3, PM10-

PRI, PM10-FIL, PM25-PRI, PM25-FIL, and PM-CON. Emissions for 21 temporal-pollutant

combinations are estimated since there are seven pollutants and three temporal periods (summer

season, winter season, July day). Note that annual SO2 and annual, summer season, and July day

NOx emission values are provided in the initial IPM scenario file. First, annual emission are

estimated by applying an SCC-based pollutant-specific uncontrolled emission factor (that may

include sulfur and/or ash content factor) to fuel 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.

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 summer season emissions from the annual emissions;

and summer day emissions are estimated by multiplying the annual emissions by a ratio of the

July day to annual heat input.

Table 10 presents the CO, VOC, NH3, PM10-FIL, and PM25-FIL emission factors by SCC.

Table 11 presents the PM-CON emission factors by SCC. For PM10-FIL and PM25-FIL,

control efficiencies (that are obtained using an EPA-approved method) are applied to the

uncontrolled emissions. PM-CON is estimated using heat input (included in the IPM run) and

emissions factors. PM10-PRI (and PM25-PRI) 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 the 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 were not provided in the 2002 NIF files. Stack

parameters were attached, first using the EPA-provided data files, secondly using a March 9,

2004 Pechan in-house stack parameter file based 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 then 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 for 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.

Step 2: Siting generic units using 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 transformed into units similar to the existing units in

terms of the available data. The generic aggregates are split into smaller generic units based on

their unit types and capacity, are provided a dummy ORIS unique plant and boiler ID, and are

given a county FIPS code based on an algorithm 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 Tribal Association of the Southeast (VISTAS).

Additional data were required for estimating VOC, CO, PM10-FIL, PM25-FIL, PM-CON, and

NH3 emissions for all units. Thus, ash and sulfur 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 were 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 that 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 the Base B point source inventory and updated to

as needed to ensure correct matching of the codes in the IPM file to state IDs in the NIF 3.0

inventory file. The revised crosswalk file was then used to obtain state and county FIPS codes,

plant IDs (within State and county), and point IDs. If the state and county FIPS codes, plant IDs

and point IDs were in the 2002 NIF tables, then the process IDs 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, NH3, 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-based heat content file, EIA-767-based

stack parameters file, and EPA-approved default stack parameters file).

3. QA Review

Pechan performed QA of the inventory by extracting the records for the CENRAP states from

the 2018 IPM run and then checking to verify that all of the records are 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 completed, and the data were transformed into their

proper format, Pechan compared the initial (from the IPM file) and final (from the SMOKE/IDA

files) NOx emission tons -- annual [summer plus winter season], summer season, summer day --

and SO2 annual [summer plus winter season] emission 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 summer 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 and included in the SMOKE IDA files.

III. SUMMARIES OF EMISSIONS INVENTORIES 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 “CENRAP Base B Emission Summaries_082205_Acc97.mdb”.

Table 16 identifies and briefly describes the contents of the emissions 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 assist in identifying the origin and year of

emissions inventory data. The data source codes were defined previously in Chapter II of this

report.

The summaries in Appendix A of this report are taken from the emissions summary Table 1D.

These summaries include natural sources NH3 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 “CENRAP 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 provided for the “All Sector” Tables 1A through 1F

series of summaries. These summaries are useful for identifying the states and sectors where

annual emissions changed significantly as a result of the comments received 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”).

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 Ontario, 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, and data units used in the raw data files was

obtained from Mr. Rob Luik (Data Management Specialist) at the Ontario Ministry of Natural

Resources (Rob.Luik@MNR. gov.on.ca). Tables 17 and 18 provide definitions of the fuel types

and other data provided in the raw data files.

B. Development of BlueSky Inputs

Emissions for each fire were estimated 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 track individual fires throughout 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 used by BlueSky but is needed by BlueSky2Inv, the

utility program that converts the BlueSky output to the SMOKE inventory format. The FIPS

code 135000 was used for all fires with longitudes 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 dates earlier than the discovery date 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 for each fire. Some of the dates provided in the original data

included hourly information. In all cases, the hourly information was not used leaving all data at

a daily resolution.

The total number of days each fire burned was determined using the start and end date for each

fire. For each fire, the size of the area burned 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. The original data included fuel type information

for each fire using the Canadian Forest Fire 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 information for these types could not be identified;

therefore, the CFFDRS types were mapped to the types used by the National Fire Danger Rating

System (NFDRS). Information about these fuel types 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 fuel 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 the 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, the vegetation type was USGS conifer, which was

mapped to NFDRS Type U (closed western long-needled pines).

All other inputs to EPM/CONSUME including meteorology-based parameters used the BlueSky

defaults.

C. Development of SMOKE Inventory Files

After running BlueSky with the prepared inputs, 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, BlueSky2Inv creates a PTHOUR file containing the

daily emissions for each fire. The data included in the PTHOUR file are daily values for the

fire’s area (AREA), heat flux (HFLUX), PM2.5, PMC (calculated as PM10 – PM2.5), CO, and total

organic gases (TOG) (calculated as methane + non-methane hydrocarbons).

BlueSky2Inv also creates an annual IDA inventory file. This file does not contain any emissions

data but serves as a master list of sources. The annual inventory also contains the latitude and

longitude of each fire. For all sources, BlueSky2Inv assigned the SCC 2810001000

(Miscellaneous Area Sources; Other Combustion; Forest Wildfires; Total).

Since BlueSky2Inv was developed for US inventories; 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 emissions 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 emissions calculated for 2002 Ontario fires. Emissions

were estimated for CO, PM2.5, coarse PM (PMC) and TOG. Note that the modeling framework

selected for estimating emissions does not include factors for estimating NOx, SO2, and NH3.
