 1 Final Report

I. INTRODUCTION 

E.H. Pechan & Associates, Inc. (Pechan) is supporting the Southeastern States Air Resource 

Managers, Inc. (SESARM) in the Southeastern Modeling, Analysis, and Planning (SEMAP) 

project that is funded by the same ten states originally involved in the Visibility Improvement – 

State and Tribal Association of the Southeast (VISTAS) project. The SEMAP project addresses 

the next phase of ozone, fine particle, and regional haze assessment obligations of the SESARM 

member states. The SEMAP project is designed to produce technical analyses to aid the 

participating agencies in developing State Implementation Plans (SIPs) required by the Clean Air 

Act. 

Pechan developed a set of draft 2007 area and nonroad source base year inventory emission 

estimates (Pechan, 2010). These estimates are reported by county and source classification code 

(SCC). These emissions inventories were developed using data from a number of sources: 

 State/local (S/L) agency emissions data; 

 2007 year emissions data compiled from running EPA’s NONROAD model with a 

combination of EPA default and S/L agency-supplied inputs; 

 2007 area source emissions estimated by Pechan, generally developed using the 

emissions estimation procedures used to prepare EPA’s draft 2008 National Emissions 

Inventory (NEI);1

 2008 commercial marine vessel and aircraft emission estimates from EPA’s draft 2008 

NEI, modified by Pechan to reflect 2007 activity levels; 

 2007 Class I line-haul locomotive emission estimates provided by the Eastern Regional 

Technical Advisory Committee (ERTAC); 

 2008 ERTAC Class II/III line-haul locomotive emission estimates, modified by Pechan to 

reflect 2007 activity levels; and 

 Emission estimates carried forward or grown from EPA’s 2002 area source NEI.2

This final inventory incorporates the following information into the draft 2007 area/nonroad 

source inventory: 

1. Additional S/L agency data and comments to revise/remove emission estimates reported 

in the draft inventory; 

2. 2007 ERTAC switchyard locomotive emission estimates; and 

3. Effects of point source subtractions on source categories for which draft area source 

emission estimates reflect total emissions activity (e.g., industrial natural gas 

combustion). 

The following sections provide additional details on the inventory development process. The 

major topics that are discussed are: 

 

1 2008 NEI methods rely on Eastern Regional Technical Advisory Committee (ERTAC) methods when available.

2

 Based on direction from S/L agencies, some 2002 NEI emission estimates were projected to 2007 using emission 

activity growth factors from Version 5.0 of the Economic Growth Analysis System (EGAS) (EPA, 2010).
PECHAN June 2010 

 2 Final Report

 How Pechan identified source categories and/or pollutants that may be missing from the 

S/L agency supplied data; 

 How Pechan integrated data from the various emission data sources (i.e., S/L agencies, 

Pechan defaults, ERTAC, and 2008 and 2002 NEI); and 

 How Pechan quality assured the integrated emissions inventory. 

The balance of this report is organized as follows. Section II describes the development of the 

stationary area source sector inventory. The development of the nonroad mobile source sector 

inventory is described in Section III. Section IV presents the area and nonroad source emission 

summaries for the final 2007 base year inventory for the SEMAP project. Section V presents the 

references that were consulted in preparing the final inventory in support of the SEMAP project.

 3 Final Report

II. STATIONARY AREA SOURCE SECTOR INVENTORY 

Pechan developed a final 2007 base year area source inventory for the SEMAP project from a 

combination of four data sources: 

1) State/Local agency supplied area source emissions data; 

2) Pechan 2007 area source emission estimates developed using the emission estimation 

methods from the 2008 NEI with adjustments to reflect 2007 emissions activity and to 

subtract point source emissions; 

3) Pechan 2007 industrial and commercial/institutional fuel combustion area source 

emission estimates specifically developed for the SESARM states; and 

4) Area source emission estimates carried forward or grown from EPA’s 2002 nonpoint 

source NEI. 

Table II-1 summarizes how these data sources were merged to create a comprehensive stationary 

area source inventory for jurisdictions covered by the SEMAP project. Although a separate fire 

emissions inventory is being developed by another contractor, in some cases S/L agencies 

requested that emissions for certain fire categories be included in our stationary area source 

inventory. The last row of Table II-1 summarizes S/L agency instructions related to Pechan 

generating emission estimates for certain fire source categories in this stationary area source 

inventory. The following sections provide more specifics on the contents of each of these data 

sources and how they were combined into the final 2007 area source inventory. 

A. AGENCY SUPPLIED INVENTORY DATA 

Last Fall, Pechan commenced area source inventory development work by providing S/L 

agencies with a Technical Memorandum documenting the emission estimation methods and data 

Pechan was using to develop the U.S. Environmental Protection Agency (EPA)’s 2008 nonpoint 

source NEI (Pechan, 2009a). The purpose of this memorandum was to provide agencies with 

information to: (1) review and comment on the methods/data, and (2) assist agencies in 

evaluating the merits of the NEI methods/data relative to any S/L area source inventory 

development efforts. State and local agencies were then provided with several months to 

compile and transmit area source emissions data to Pechan. 

Two state agencies (North Carolina and Virginia) and two local agencies (Jefferson County, 

Kentucky and Davidson County, Tennessee) provided area source data for the draft area source 

inventory (two additional local agencies provided data for the final area source inventory – Knox 

County and Shelby County, Tennessee). After receiving these S/L agency data, Pechan 

compared the source classification code (SCC) and pollutant coverage of these submittals against 

the SCCs/pollutants in the 2007 emissions data that Pechan was developing for this project 

(hereafter referred to as the “Pechan default inventory”). 

To assist in obtaining direction from SESARM agencies on how to merge the data from these 

sources, Pechan first identified the SCC/pollutant combinations in the Pechan default inventory 

that matched to S/L agency data. Next, Pechan reviewed remaining S/L agency SCC/pollutant 

combinations against Pechan defaults to identify whether it may be possible that these emissions

were covered in the Pechan default inventory under different SCCs. Pechan then developed a list 

of potential indirect matches between the two data sets for agency review. This list was 

compiled in an Excel worksheet. Next, Pechan developed a separate worksheet that listed 

SCC/pollutant combinations in the S/L supplied area source inventory that we were unable to 

either directly or indirectly match to combinations in the Pechan default inventory. A list of 

SCC/pollutant combinations in the Pechan default inventory that we were unable to directly or 

indirectly match to combinations in the S/L agency inventory was also prepared in a separate 

worksheet. Finally, Pechan developed a worksheet that contained all S/L agency inventory 

SCC/pollutant combinations with emissions equal to “0.” The above worksheets were saved in a 

single Excel workbook for each Agency. In addition to these workbooks, Pechan transmitted a 

Word document identifying questions on how two merge the two data sets (e.g., where S/L 

agency emissions are reported as zero, should Pechan replace any of these with emissions from 

the Pechan default inventory?). After reviewing S/L agency responses to these questions, 

Pechan transmitted any follow-up questions that were necessary to clarify S/L agency guidance. 

B. DEVELOPMENT OF PECHAN DEFAULT 2007 AREA SOURCE 

INVENTORY 

Pechan created a default 2007 area source inventory that includes all of the source categories 

covered by the 2008 nonpoint source NEI. For all source categories except industrial and 

commercial/institutional (ICI) fuel combustion, Pechan either directly incorporated emissions 

data from the 2008 nonpoint source NEI (when the NEI represented use of 2007 emissions 

activity data), or recalculated the NEI emission estimates to reflect 2007 activity levels (when the 

NEI reflected 2006 or 2008 activity levels) and/or to remove emissions associated with activity 

reflected in the point source inventory. For ICI fuel combustion, the 2008 nonpoint source NEI 

only developed emissions activity estimates, not emission estimates. Because of the potential 

importance of these source categories and the availability of methodological improvements, 

Pechan utilized an emissions estimation method for ICI fuel combustion that is incorporates a 

few refinements to the NEI method. The following section discusses how information from the 

2008 nonpoint source NEI was used in this project. The subsequent section provides details on 

the ICI fuel combustion emissions estimation methods. 

1. Nonpoint Source NEI 

Pechan is supporting EPA efforts to develop the 2008 nonpoint source NEI. Because of data 

availability issues, the 2008 NEI is comprised of data of various vintages (2006-2008). 

Table II-2 provides documentation of the 2008 nonpoint source NEI as follows: 

(1) Source Category – identifies the name of each general source category covered. 

(2) Source Classification Code(s) – lists the SCCs that are inventoried. 

(3) Source Classification Code Description – provides a description of each SCC.

10 Final Report 

(4) Link to Emission Calculation Documentation – provides links to the detailed 

documentation of the NEI methods;3

(5) Link to Emission Calculation Workbook – provides a link to the draft 2008 NEI 

emissions or activity data; 

(6) Year of Activity Data – identifies the year represented by the emissions activity data; and 

(7) Point Source Component – signifies whether a portion of the source category’s emissions 

may be included within the point source inventory. 

a. Adjustment of NEI Data to Reflect 2007 Activity Levels 

Where the 2008 nonpoint source NEI reflects 2007 activity data, Pechan incorporated the 2008 

NEI emission estimates into the Pechan default inventory for this project. When a source 

category’s NEI data reflect 2006 or 2008 emissions activity data, Pechan updated the NEI 

estimates to reflect 2007 emission activity levels. Table II-3 documents the specific revisions 

that were implemented. 

For many area source categories, emissions activity data are not available at the county-level. In 

these cases, county-level emissions are estimated using two sets of activity data: one set 

reflecting state or regional-level emissions activity (e.g., volume of natural gas consumed by the 

residential sector in each state), and the other set representing data that are used to allocate 

emissions activity to the county-level (e.g., number of houses using natural gas as the primary 

heating fuel in each county). Specifically, the “Backcasting or Forecasting Methodology” 

column in Table II-3 presents the approach used to update emissions activity data to represent 

2007, and the “County Allocation Method” column identifies the approach used to update the 

county allocation data. As noted in Table II-3, all county allocation data were not updated to 

2007. This approach was taken because of the level-of-effort that would be involved in updating 

some of the allocation data, and the fact that these data are often not expected to differ 

significantly from year-to-year. 

b. Adjustment of NEI Data to Remove Activity Reflected in the Point Source Inventory 

To prevent double-counting of emissions in the stationary point source and area source emissions 

inventories, it was necessary to perform point source subtractions on some of the source 

categories in the Pechan default inventory. To facilitation the point source subtractions, Pechan 

prepared crosswalks that link area SCCs to point SCCs. These crosswalks are presented in 

Appendix A. The general point source subtraction approach consisted of the following steps: 

1. Compile 2007 point source emissions and control efficiency data provided by each state 

for the applicable point SCCs. 

2. Identify potential quality assurance issues for S/L agency review; 

3. Revise control efficiency data to incorporate S/L agency comments;

 15 Final Report

4. Back-calculate 2007 uncontrolled point source emissions from reported emissions and 

control efficiency data -- e.g., 40 tpy of controlled NOx emissions and 80% control 

efficiency = 50 tpy of uncontrolled NOx emissions. 

5. Sum the emissions for each record from step 4 to the state-level to yield state total 

uncontrolled point source emissions by pollutant. 

6. For each pollutant and state, compute the fraction of total 2007 state-level emissions in 

the 2007 Pechan default inventory represented by area sources (using step 5 total point 

source uncontrolled emissions). 

7. Multiply the emission estimates in the draft base year inventory by the appropriate 

percentages in step 6 to yield area source emissions. 

With the exception of Georgia, Pechan performed the point source subtractions at the staterather than county-level because of the uncertainty associated with the NEI county emission 

allocations in that actual county-level emissions activity data are generally not available (i.e., a 

surrogate indicator such as employment is typically used to allocate state-level activity to 

counties).4

 However, at Georgia’s request, Pechan performed Georgia’s point source 

subtractions at the county-level. 

As part of step 2, Pechan identified a significant number of PM-PRI and PM-FIL point source 

control efficiency records. These data could not be directly used in the point source subtraction 

procedure because all point source emissions data are provided for PM10, PM2.5, or PM-CON. 

For the PM-FIL records, Pechan was able to use EPA’s PM calculator database to compile 

PM10-FIL and PM2.5-FIL control efficiency values.5 Pechan specifically linked the PM 

calculator database’s PM10-FIL and PM2.5-FIL emission control efficiency values to SEMAP 

point source inventory PM-FIL control efficiency records using the SCCs and emissions control 

device codes that are reported in the SEMAP inventory. These control efficiency values were 

then applied to the point source PM10-FIL and PM2.5-FIL emission records to estimate 

uncontrolled PM10-FIL and PM2.5-FIL emissions. In lieu of any better information, we 

assumed that the PM-FIL control efficiencies had no effect on PM-CON emissions. Pechan then 

summed the estimated uncontrolled PM10-FIL and PM2.5-FIL emissions with the PM-CON 

emissions to estimate uncontrolled point source PM10-PRI and PM2.5-PRI emissions. This 

procedure yielded uncontrolled emission estimates for all six PM species. 

Because of the inconsistent reporting of throughput data in the SEMAP point source inventory, 

throughput data were used in the point source subtraction procedure in only a limited number of 

cases. These cases are listed below in Table II-4. For these areas/SCCs, all pollutants’ total 

emissions are adjusted by the same percentage. For a few area source categories, it was 

necessary to incorporate source category-specific point source subtraction procedures. Appendix 

A summarizes the specific point source subtraction approaches for these source categories. 

 

4 Efforts to perform subtractions at the county-level commonly result in negative emission estimates. 

5 Because the PM calculator database requires PM-FIL input data., it was not possible to use the PM-PRI control 

efficiency records to estimate uncontrolled emissions.

2. Estimation of Area Source Emissions from Industrial and Commercial/Institutional 

Fuel Combustion 

Currently, the 2008 NEI data for the ICI fuel combustion categories represent total emission

activity estimates, rather than area source emission estimates. Because emission estimates are 

not available and because of the relative importance of this category, Pechan recommended that 

2007 ICI combustion area source emission estimates be developed as part of this project. This 

section documents the emission inventory development methodology that Pechan used in 

preparing 2007 year ICI fuel combustion area source emission estimates for the SESARM states. 

The following are elements of the methodology that provide improvements over the 2008 NEI 

methodology: 

 Obtained Industrial and Commercial/Institutional energy consumption by fuel type and 

SESARM state for the year 2007 from the Energy Information Administration (EIA)’s 

State Energy Data System (SEDS) – the 2008 NEI uses 2006 year data; 

 Obtained geographic- and year-specific estimates of non-fuel use consumption of 

industrial energy from the 2006 Manufacturing Energy Consumption Survey (MECS) – 

the 2008 NEI uses data from the 2002 MECS survey; 

 Applied a county allocation procedure that reflects the energy-intensity of each industrial 

sector – the 2008 NEI methods only reflect the number of employees in each sector; and 
PECHAN June 2010 

 17 Final Report

 Updated SO2 emission factors to reflect coal sulfur content estimates for coal used in the 

industrial sector in 2007 – a recent review of industrial coal sulfur content values 

concluded that the NEI values are based on unrepresentative data (Pechan, 2009b). 

Table II-5 identifies the SCCs for which Pechan prepared ICI fuel combustion area source 

emission estimates. The key data inputs in the emissions estimation methodology are: 

1. Total Industrial and total Commercial/Institutional energy consumption by fuel type and 

SESARM state for the year 2007; 

2. Estimates of the percentage of total ICI distillate fuel and liquefied petroleum gas (LPG) 

consumption from stationary sources; 

3. Industrial energy consumption used for non-fuel purposes by fuel type and state in 2006; 

4. ICI energy consumption by fuel type for point sources by SESARM state in year 2007; 

5. Emission factors relating emission rates to volume of energy consumed by fuel type for 

the ICI sectors; 

6. Sulfur content of coal consumed in the ICI sectors by state in year 2007; 

7. County-level Industrial sector energy consumption estimates by state for year 2007; and 

8. County-level Commercial/Institutional sector employment by state for the year 2006.6

 To conserve project resources, Pechan will rely on 2006 employment data compiled in support of the 2008 NEI 

rather than develop 2007 employment data (note that year-to-year county employment proportions are expected to 

remain relatively constant). 
PECHAN June 2010 

 18 Final Report

The following sections describe the methodology/data source(s) for developing each of these 

data inputs, and the source(s) of information for each of these data elements. In selecting the 

information sources for each of these data elements, Pechan evaluated the completeness, 

representativeness, comparability, and accuracy criteria identified in the Quality Assurance 

Project Plan (QAPP) for this project. For example, information sources that provide data 

specific to the source category/geography/inventory period were selected over those that were 

less specific. 

a. Total ICI Energy Consumption 

For total Industrial and total Commercial/Institutional energy consumption by fuel type/state, 

Pechan primarily used the same source that EPA uses in developing ICI combustion emission 

estimates for the NEI –EIA’s SEDS (EIA, 2009a). The SEDS provides total energy consumption 

estimates by sector, state, fuel type, and year. To facilitate use with the criteria pollutant 

emission factors, Pechan compiled the SEDS energy consumption data in both sets of units 

provided by the EIA: physical units and British thermal units (Btus). For estimates of industrial 

distillate consumption, Pechan relied on estimates reported in EIA’s “Fuel Oil and Kerosene 

Sales” (EIA, 2009b). This source is preferred over the SEDS data because it provides additional 

sectoral detail that is needed to perform the stationary source energy consumption adjustments 

described below. 

b. Stationary Source Energy Consumption 

To avoid double-counting with energy consumption accounted for in mobile source inventories, 

it was necessary to adjust 2007 year SEDS distillate and LPG consumption estimates for mobile 

source fuel consumption. For LPG, the adjustments account for energy consumption reflected in 

the nonroad mobile sector. The adjustments were performed by subtracting estimated 

proportions of total Industrial sector and Commercial sector consumption computed from a 

national NONROAD model run. Pechan compiled national LPG consumption estimates for 

relevant SCCs from a 2006 run of EPA’s NONROAD model (a 2006 run was performed in 

support of the NEI—it is not anticipated that the percentages differ considerably between 2006 

and 2007). Table II-6 identifies a complete list of nonroad SCCs associated with Industrial and 

Commercial sector LPG. The shaded entries in this table indicate where NONROAD reports 

LPG consumption. This procedure estimates that nonroad mobile sources account for 9 percent 

of Industrial sector, and 18 percent of Commercial sector LPG consumption. The SEDS LPG 

consumption estimates for each state/sector were adjusted downward using these percentages. 

For distillate oil, it was necessary to remove energy consumption reflected in onroad/nonroad 

mobile source emission inventories. To facilitate this step, Pechan used more detailed distillate 

fuel consumption estimates reported in EIA’s “Fuel Oil and Kerosene Sales,” and stationary 

source fuel consumption percentage assumptions used in the regulatory impact analysis for 

EPA’s nonroad diesel emissions rulemaking (EPA, 2003a). Table II-7 displays the assumptions 

that were applied to the state-level Industrial sector distillate fuel consumption estimates reported 

in “Fuel Oil and Kerosene Sales” to estimate Industrial sector stationary source consumption. 

Table II-8 identifies the assumptions that were applied to estimate total stationary source 

Commercial/Institutional sector consumption.

 This value differs from the 0% assumption adopted in EPA’s nonroad diesel emissions rulemaking 

because it is known that some diesel fuel is used by stationary sources (a 15 percent value was 

selected for use as an approximate mid-point of a potential range of 8 to 24% stationary source use 

computed from a review of national data from the EIA’s Manufacturing Energy Consumption Survey

and “Fuel Oil and Kerosene Sales”).

 A very small portion of total commercial/institutional diesel is actually consumed by point sources (SCC

c. Non-Fuel Energy Consumption 

Some Industrial sector energy is consumed for non-fuel purposes. For example, natural gas is 

used as a feedstock in chemical manufacturing plants and to make nitrogenous fertilizer, and 

LPG is used to create intermediate products that are made into plastics. To estimate the volume 

of fuel that is associated with ICI combustion, it is necessary to subtract the volume of fuel 

consumption for non-energy uses from the volume of total fuel consumption. The EPA’s State 

Inventory Tool (SIT) provides national defaults representing the percentage of total Industrial 

fuel consumption from non-energy uses. These default values have an additional limitation 

beyond their lack of geographic detail - they represent the EIA’s definition of the Industrial 

sector, which includes fuel use that is accounted for in other inventory source categories (e.g., 
PECHAN June 2010 

23 Final Report

Farm, Mining, Construction, and Commercial sectors fuel use that is accounted for in the 

nonroad inventory). Because of these limitations, Pechan used regional non-fuel use percentages 

computed from energy consumption data from the EIA’s 2006 Manufacturing Energy 

Consumption Survey (MECS) for all fuel types (EIA, 2009c). 

There are two reasons why MECS provides a more representative data set for use in this project: 

(1) MECS provides data specific to the region of interest; and (2) MECS focuses solely on the 

Manufacturing sector. The latter characteristic is particularly important for fuel types which 

consume significant amounts of non-Manufacturing sector energy that is already included 

elsewhere (e.g., distillate fuel used by the Construction sector, which is included in the nonroad 

inventory). The MECS non-fuel consumption data treat coal that is used to produce coke as a 

feedstock (Lorenz, 2009). However, available data indicate that only four of the SESARM states 

produce coke (Alabama, Kentucky, Virginia, West Virginia; EIA, 2008a) and coke combustion 

is not included in the area source emissions inventory. Because of this, Pechan estimated the 

percent energy consumption from non-fuel use for SESARM states without coke plants by 

subtracting the coal used in the primary metals industrial subsector (NAICS code 331*) from the 

MECS coal dataset. More than 97 percent of coking coal is ultimately consumed in this 

subsector (Lorenz, 2009). Table II-9 presents the non-fuel use percentages by type of energy.

d. Emission Factors 

Table II-10 presents the criteria pollutant emission factors that Pechan used in calculating ICI 

combustion area source emissions. Except as noted below, all criteria air pollutant emission 

factors are from an EPA database used to prepare the 2008 nonpoint source NEI (Huntley, 

2009).7

 Wood combustion emission factors are from AP-42 (EPA, 2003b). Because there are no 

NH3 emission factors for ICI fuel combustion available in the 2008 NEI emission factor 

database, AP-42, or EPA’s WebFIRE, Pechan used emission factors reported in an NH3 

emissions Emission Inventory Improvement Program (EIIP) guidance document (Pechan, 2004).

 All criteria pollutant emission factors were rounded to two decimal places.

 25 Final Report

With a few notable exceptions, the 2008 NEI emission factors are the same as those used for the 

2002 NEI.8

 The PM emission factors for natural gas and LPG combustion are the major 

exceptions. Because the 2002 emission factors were deemed too high because of artifact 

formation in the test method (method 202) during stack testing, EPA developed a set of SCCspecific adjustment factors to apply to the 2002 NEI to better reflect PM emissions from these 

fuels.9

 In preparation for the 2008 NEI, EPA developed revised natural gas PM emission factors 

by applying these adjustment factors to the 2002 NEI emission factors. Revised emission factors 

for LPG were computed by applying appropriate conversion factors to the updated natural gas 

emission factors. 

e. Coal Sulfur and Ash Content 

For a recent ICI combustion area source inventory project for the Central Regional Air Planning 

Association (CENRAP), Pechan evaluated the reliability of various data sources for coal sulfur 

content to be used to estimate emissions in that project. Pechan evaluated five potential data 

sources: 

1. 2002 CENRAP state point source inventories; 

2. U.S. Geological Survey (USGS)’s U.S. Coal Quality Database; 

3. Energy Information Administration (EIA)’s “Cost and Quality of Fuels for Electric Plants 

2002 and 2003.” 

4. EIA’s “EIA-423 - Monthly Nonutility Fuel Receipts and Fuel Quality Data, 2002;” and 

5. EIA’s “Quarterly Coal Report, January–March 2003.” 

Pechan evaluated these coal sulfur content data sources with respect to two specific criteria 

identified in the QAPP for this project: representativeness and accuracy. Based on these 

evaluations, Pechan used the average sulfur content data from EIA’s “Quarterly Coal Report” to 

estimate the sulfur content of both Industrial and Commercial/Institutional sector bituminous/

subbituminous coal in each SESARM state (EIA, 2008b). Even though this source does not 

report whether the coal is bituminous/subbituminous or anthracite, it is appropriate to treat the 

values for this source as representative of bituminous/subbituminous coal because anthracite 

accounts for only a very small proportion of coal consumption in SESARM states. 

Due to the lack of available data for anthracite coal, Pechan used the average ash content 

(13.38 percent) and sulfur content (0.89 percent) from the 2002 NEI for the Industrial and 

Commercial/Institutional sectors. These percentages are based on the composition of anthracite 

coal seams in Pennsylvania, where all anthracite coal imported by SESARM states originated in 

2007 (EIA, 2008c). Tables II-11 and II-12 report the coal ash and/or sulfur content values that 

were used in calculating ICI combustion area source emissions for the 2007 base year inventory. 

 

8

 The 2002 NEI documentation provides citations to the AP-42 source for each emission factor. 9

 These factors reduce PM emissions by more than 90 percent.

 27 Final Report

f. County Allocation Data 

After computing state-level area source emissions using the data described above, the next step is 

to allocate these emissions to individual counties. Separate allocation approaches were 

implemented for the Industrial and Commercial/Institutional sectors. For Commercial/

Institutional sector source categories, the approach relies on county employment data compiled 

from government sources. For Industrial sector source categories, the approach utilizes countylevel Industrial sector energy consumption estimates developed in this effort. 

Commercial/Institutional 

Because SEDS data originate from EIA fuel sector-specific surveys of energy suppliers,10 Pechan 

reviewed these survey forms/instructions for further details on what SEDS considers 

Commercial sector use of each fuel. This review found that the surveys/guidance do not always 

provide further clarity. In addition, the EIA has admitted that energy suppliers may use their 

own account classifications as well as EIA guidance in determining whether a particular account 

belongs in the Residential, Commercial, Industrial, or Transportation sector. The only source of 

NAICS-code based EIA definitions of the Commercial energy sector is a “rough crosswalk” 

between Commercial building types and NAICS codes developed for EIA’s Commercial 

Building Energy Consumption Survey (CBECS). With the exception of NAICS code 814 

(Private Households), this crosswalk links all NAICS codes between 42 and 92 with Commercial 

building energy consumption. Employment data for the CBECS-identified NAICS codes (42 

though 92 with exception of 814) were used to allocate SEDS energy consumption data to 

individual counties. Pechan used private sector 2006 employment data from County Business 

Patterns (CBP) and public sector 2006 employment data from the Census of Governments

(Census, 2009a; and Census, 2009b) because these data were already compiled in support of the 

2008 NEI (year-to-year changes in county employment proportions are expected to be minimal). 

Industrial 

Unlike the Commercial sector, documentation provides a clear listing of the NAICS codes 

associated with SEDS Industrial energy consumption data: “the industrial sector encompasses 

the following types of activity: Manufacturing (NAICS codes 31–33); Agriculture, Forestry, 

Fishing and Hunting (NAICS code 11); Mining, including Oil and Gas Extraction (NAICS code 

21); and Construction (NAICS code 23).” As noted earlier, a portion of Industrial sector 

consumption (Agriculture, Mining and Construction) is already accounted for in other emission 

inventory sectors and was removed. Therefore, Pechan did not expand the list of NAICS codes 

used to represent the area source Industrial fuel combustion category beyond the Manufacturing 

sector NAICS codes (31-33). 

Employment-based county allocation methods lead to overrepresentation of energy consumption 

in counties with sectors that have high employment but low energy intensities (measured on a 

Btu per employee basis), and vice-versa. Given that Manufacturing sectors have much greater 

energy intensity variability than Commercial/Institutional sectors, Pechan utilized energy use per

Disposition.”

 28 Final Report

employee values by NAICS code to improve upon the employment-based county allocation 

approach used in the 2008 NEI for the Industrial fuel combustion category. This procedure 

relied on 2007 national energy consumption data by NAICS code as reported by EIA in Annual 

Energy Outlook (EIA, 2009d). Energy intensity values were computed by dividing these Btubased energy consumption estimates by NAICS code-level 2007 national employment data. The 

resulting intensity values were then multiplied by county/NAICS code-level employment 

estimates from CBP to estimate total county energy consumption by NAICS code. These values 

were then summed for the appropriate Industrial fuel combustion NAICS codes. The resulting 

county-level total Industrial energy consumption estimates were used to apportion state-level 

area source Industrial fuel combustion emissions to each county. 

Estimation of Withheld Employment Data 

Due to concerns with releasing confidential business information, the CBP withholds values for a 

given county/NAICS code if it would be possible to identify individual businesses from these 

values. In such cases, the CBP reports a letter code, representing a particular employment size 

range. Pechan used the following procedure to estimate data for withheld counties/NAICS 

codes. 

1. County-level employment for counties with reported values are totaled by state for the 

applicable NAICS code. 

2. Value from step 1 is subtracted from the state employment value for the NAICS code. 

3. Each of the withheld counties is assigned an initial employment estimate reflecting the 

midpoint of the CBP range code (e.g., code A, which reflects 1-19 employees, is assigned an 

estimate of 10 employees). 

4. The initial employment estimates from step 3 are then summed to the state level. 

5. The value from step 2 is divided by the value from step 4 to yield an adjustment factor to 

apply to the initial employment estimates to yield employment values that will sum to the 

state employment total for the applicable NAICS code. 

6. The final county-level employment values are estimated by multiplying the initial 

employment estimates from step 3 by the step 5 adjustment factors.

C. INVENTORY SUPPLEMENTATION/FINAL DATA MERGING 

As directed by S/L agencies, Pechan supplemented 2007 S/L agency supplied emissions data 

(when supplied) and Pechan default emissions data with emissions data from the 2002 nonpoint 

source NEI, or in the case of Georgia, the state’s 2005 Consolidated Emissions Reporting Rule 

(CERR) submittal. To assist agencies that supplied S/L emissions data, Pechan compiled a list 

of SCC/pollutant combinations in the S/L area’s portion of the 2002 nonpoint source NEI that 

did not match to combinations in either the S/L agency inventory or Pechan’s default inventory. 

This list was documented in an Excel worksheet and transmitted along with a request for 

agencies to identify whether each combination’s emissions should be carried forward or grown 

to 2007 using EGAS growth factors. Pechan contacted agencies with any necessary follow-up 

questions to clarify guidance on the NEI supplementation procedure. 

To assist agencies that did not supply their own emissions data, Pechan compiled a list of 

SCC/pollutant combinations in the state’s portion of the 2002 nonpoint source NEI that did not 

match to combinations in Pechan’s default inventory. These lists were documented in an Excel 

workbook, which also contained a worksheet identifying associated inventory supplementation

questions (e.g., “the 2002 NEI reports VOC emissions under Dry Cleaning/Perchloroethylene 

SCCs—Pechan’s default inventory does not include VOC emissions for this SCC because 

perchloroethylene is no longer considered a VOC by EPA. Please confirm that VOC emissions 

from these SCCs should not be carried forward/grown”). After reviewing state agency responses 

to these data merging questions, Pechan contacted agencies with follow-up questions as 

necessary to clarify state guidance. 

Table II-13 displays the SCC/pollutant combinations for which 2002 nonpoint source NEI 

emissions were carried forward or grown to 2007 using growth factors from EGAS.11 Further 

documenting the data merging procedures are NIF EM table records and the SCC/county-level 

emission summaries that display a data source code for each record. Table II-14 presents the 

data source codes used to document the source of each area source emission record. The 

compiled inventory was converted into EPA’s NIF 3.0 nonpoint source format.12 

 

11 Note that for some SCCs, EGAS did not provide growth factors. In these cases, Pechan used underlying EGAS 

5.0 information (i.e., the EGAS Version 5.0 SCC-to-growth indicator crosswalk and economic output data from 

version 5.5 of the Regional Economic Models, Inc. [REMI] model) to develop growth factors.

12 Pechan removed throughput data when 2002 nonpoint source NEI data were carried forward,

In addition to the quality assurance procedures that Pechan performed on the draft 2007 

stationary area source inventory (e.g., running EPA’s NIF QA/Content Checker program to 

check for referential integrity issues, invalid entries, and out of typical range values), Pechan 

quality assured all updates provided by state/local agencies to ensure that they were correctly 

incorporated into the final inventory, and reviewed the ratios of post-point source subtraction 

emissions to pre-point source subtraction emissions to confirm that these subtractions were 

properly implemented.13

 

13 It is important to note that it was not possible to perform the PM10-PRI and PM2.5-PRI emissions check that was 

implemented on the draft area source inventory because the point source subtraction procedure does not require that 

the sum of PM10-FIL plus PM-CON emissions and PM2.5-FIL and PM-CON emissions equal PM10-PRI and 

PM2.5-PRI emissions, respectively.

 35 Final Report

III. 2007 NONROAD MOBILE SOURCE INVENTORY 

The nonroad sector is comprised of nonroad engines included in EPA’s NONROAD model, as 

well as other engines not modeled in NONROAD, including aircraft, commercial marine vessels 

and locomotives. A 2007 nonroad sector inventory was developed using the following general 

procedures: 

 NONROAD model categories were based on the National Mobile Inventory Model 

(NMIM2008). SESARM agencies were asked to review the latest 2007 NMIM County 

Database and provide revisions as needed to the NMIM inputs. 

 The aircraft category was based on EPA’s 2008 NEI. The 2008 estimates were backcast 

to 2007, and any state comments were incorporated. 

 The commercial marine vessel category was based on EPA’s 2008 NEI, adjusted to 2007, 

and supplemented with any state emissions data. 

 The locomotive category was based on draft Class I and Class II/III line haul emissions, 

as well as draft railyard emissions developed by ERTAC. Passenger and commuter rail 

emissions were based on EPA’s 2002 NEI. State emission estimates were also included. 

A more detailed description of how 2007 emissions estimates for all nonroad categories were 

prepared is provided below. 

A. NONROAD MODEL CATEGORIES 

NONROAD model categories include equipment such as recreational marine and land-based 

vehicles, farm, construction and industrial machinery, and lawn and garden equipment. These 

equipment are powered by compression-ignition engines, which are typically diesel-fueled, as 

well as spark-ignition or gasoline-fueled engines. Compressed natural gas (CNG) and LPG 

engines are also included in the NONROAD model. Criteria pollutant emissions may not be 

reported for all SCCs for all counties in the SESARM region, and will depend on the geographic 

allocation methods used by the model, or state-specific allocation data.

NMIM2008 incorporates EPA’s latest NONROAD model (NONROAD2008) released in April 

2009, and reflects all of EPA’s final nonroad standards to date. Pechan first distributed the 2007 

year NMIM county-level database (NCD) to SESARM agencies for review and comment. 

Pechan prepared a report to accompany nonroad-related tables from the 2007 NCD providing 

instructions for agencies to provide any updates to these files that may represent S/L/T 

improvements to the NMIM/NONROAD defaults (Pechan, 2009d). A summary of the tables 

distributed and comments received from states is provided in Table III-1.

related to underground mining equipment in their state. This revised county distribution was 

based on 2007 Underground Coal Production values as reported by the West Virginia’s Office of 

Miners' Health Safety and Training 2007 Coal Production by County. 
PECHAN June 2010 

 37 Final Report

CountyYearMonth, Gasoline, and Diesel Tables 

Several states provided revised fuel profile assignments by county, as reflected in changes to the 

CountyYearMonth table. In many cases, this also involved the creation of new gasoline profiles 

in the Gasoline table. The revisions submitted primarily related to changes by month for Reid 

Vapor Pressure (RVP) values as well as gasoline sulfur content. Updates to the oxygenated fuel 

data were provided for some states as well. 

Some states also revised the diesel fuel sulfur content values for 2007. For regional consistency, 

unless the values were based on actual testing that reflected the diesel sulfur content in use for an 

area, the NMIM default values of 1218 parts per million (ppm) for land-based equipment 1389 

ppm for recreational marine were retained. 

Once the inputs to NMIM/NONROAD were quality assured, Pechan ran NMIM to generate 

2007 annual emission estimates for all SESARM states for all nonroad SCCs. Emissions from 

aircraft ground support equipment are now entirely addressed by the aircraft sector inventory 

(see discussion under Section III.B of this report). Pechan removed emission estimates from the 

NMIM output for the airport GSE SCCs (i.e., SCCs 2265008005, 2267008005, and 

2270008005).

2007 aircraft emissions were primarily based on EPA’s 2008 NEI. The procedures and data for 

developing aircraft emissions are described in further detail in EPA’s 2008 NEI documentation 

(EPA, 2009a). 

For commercial aircraft, the emission estimation methodology relied on airport and aircraftspecific landing and take-off (LTO) data, coupled with mode and aircraft-specific emission rates 
PECHAN June 2010 

 38 Final Report

from the FAA’s Emission and Dispersion Modeling System (EDMS). Emissions for ground 

support equipment (GSE) and auxiliary power units (APUs) associated with commercial air 

carriers were estimated by EDMS, using operating time defaults based on the type of service 

performed. LTO data for general aviation and air taxi were obtained from FAA’s Terminal Area 

Forecasts (TAF) and 5010 Forms. This activity was assigned to jet and propeller-driven 

fractions, and fleet-average emission factors were then applied. 

A portion of the military aircraft LTO is also reported by the FAA’s TAF and incorporated into 

the NEI and the SEMAP inventory. Emissions for military aircraft were only available for VOC, 

NOx, CO, and SO2, with no PM being reported. Since development of the initial draft SEMAP 

inventory, EPA made additions to the 2008 military aircraft emission estimates. However, many 

agencies have already reviewed and provided comments on the draft inventory compiled for 

SESARM. We are providing an electronic file showing additional emission records calculated 

by EPA for military aircraft by airport for the SESARM region. These records (with a few noted 

exceptions) are currently not incorporated in the inventory. Pechan is requesting feedback from 

each agency as to whether these records should be added to their inventory, or left out since 

military operations may already be adequately accounted for. 

The 2008 emissions and LTO data were back-cast to 2007 using approach operations by airport 

and aircraft type compiled from the FAA’s Air Traffic Activity Data System (ATADS) (FAA, 

2010). The airport-level LTOs were assigned to counties and summed for the county. For 

counties with aircraft emissions without a county match in ATADS, state average growth factors 

were calculated and applied. The county-level growth factors are not presented in this report, but 

could be provided to SESARM if requested. The 2007 to 2008 growth factors were developed 

for each of the six airport source categories. Commercial aircraft, APU, and GSE categories 

relied on growth factors calculated from commercial air carrier LTOs. General aviation and air 

taxi were grown using LTO data reported for these specific aviation categories. Military aircraft 

were held constant from 2008 to 2007. 

State-supplied data are summarized in Table III-3. Comments from Alabama, Georgia, and 

Davidson County, Tennessee related to removing non-operational airports, correcting county 

assignments for individual airports, or updating emissions for specific commercial airports. 

Georgia, North Carolina, and Virginia submitted military aircraft emissions for military bases in 

their state. In addition, North Carolina provided emissions for military aircraft activity at 

commercial airports, and also provided diesel GSE emissions associated with all military aircraft. 

Note that for several North Carolina facilities, EPA had already reported diesel GSE emissions 

associated with commercial aircraft activity, so state-provided diesel GSE emissions were added 

to these existing EPA estimates at the SCC level.

provided by Virginia for two facilities, we estimated PM-2.5 using a particle size multiplier of 

0.669, from Table “Military Aircraft Emission Factors” in Appendix A to EPA 2008 NEI 

documentation (ERG, 2009a). PM emissions for the remaining military facilities in Virginia 

were not estimated. 

C. COMMERCIAL MARINE VESSELS 

Commercial marine vessel emissions are reported under the following SCCs: 

 2280002100 – Diesel, In Port 

 2280002200 – Diesel, Underway 

 2280003100 – Residual, In Port 

 2280003200 – Residual, Underway 

For the purpose of the NEI it was assumed that Category 1 and 2 vessels typically use distillate 

fuels, while Category 3 vessels primarily use residual blends. Category 3 engines are defined as 

having displacement above 30 liters per cylinder. 
PECHAN June 2010 

 40 Final Report

2007 CMV emissions were based largely on EPA’s 2008 NEI. For Category 1 and 2 engines, 

national diesel emissions, based on national 2008 fuel sales, were split into near-shore port and 

underway components. Port emissions were assigned to 150 largest ports using port traffic data 

per Waterborne Commerce of the U.S. For the county allocation procedure, EPA developed a 

GIS shape file library based on Bureau of Transportation data to more precisely assign port 

emissions to counties, and to better allocate underway emissions to line segments/counties. This 

represents an improvement to the spatial allocation procedure used for previous versions of the 

NEI. 

2008 Category 3 CMV estimates were projected from a 2002 hourly modeling inventory 

developed by EPA’s Office of Transportation and Air Quality (OTAQ), and aggregated to an 

annual basis for the NEI. EPA developed Category 3 inventories for a total of 117 deep sea and 

inland ports, accounting for 4 different types of near-port emissions, including hotelling, 

maneuvering, reduced-speed zone, and cruise mode. EPA spatially allocated emissions using 

GIS shapefiles to specify the geographic locations for each type of near port emissions. 

Additional details concerning the methodologies are described in EPA’s 2008 NEI 

documentation (EPA, 2009b). 

The 2008 CMV estimates were then adjusted to represent 2007. For Category 1 & 2 diesel 

commercial marine vessels, 2007 emissions were estimated by applying growth factors to the 

2008 emissions. National 2007 and 2008 emissions, by pollutant, were used to estimate the 

growth factors (EPA, 2008a). Emissions were adjusted at a national level because the surrogate 

data used to estimate county-level emissions for the 2008 NEI actually represent year 2007. 

Table III-4 shows the growth factors, by pollutant. The PM10-PRI and PM25-PRI growth factor 

value was also used for NH3.

NOx 1.016 

PM10-PRI 1.045 

PM25-PRI 1.045 

SO2 1.110

To estimate 2007 emissions for Category 3 residual commercial marine vessels, an annual 

average regional growth rate was applied as a corresponding decrease to the 2008 NEI emissions 

(EPA, 2008b). A correspondence was developed between the SESARM states and available 

regional growth rates for the East Coast and Gulf Coast. Table III-5 contains this 

correspondence along with the growth factor. Counties in the state of Florida were assigned to 

the two regions as appropriate.

State provided data are listed in Table III-6. South Carolina provided a county-level inventory 

for the port of Charleston for 2005. The 2005 estimates were grown to 2007 using Army Corps 

of Engineers data on total commodity tonnage handled at the Port of Charleston (ACE, 2010). 

Davidson County provided a county-level CMV inventory reported under the general SCC 

2280000000. Finally, Virginia also provided a military marine emissions inventory, with the 

exclusion of Coast Guard Vessels, since activity for these ships should be captured by EPA’s 

Category 1 & 2 inventory. The port and underway components of Virginia’s marine inventory 

were assigned to the Residual, In Port and Residual, Underway SCCs, respectively. In counties 

where EPA had already reported residual port or underway emissions, state-provided military 

marine emissions were added to these existing EPA estimates at the SCC level. Any necessary 

pollutant augmentation is described in Table III-6.

D. LOCOMOTIVES 

Locomotive emissions are reported under the following SCCs: 

 2285002006 – Diesel Class I Line Haul 

 2285002007 – Diesel Class II/III Line Haul 

 2285002008 – Diesel Passenger (Amtrak) 

 2285002009 – Diesel Commuter 

 2285002010 – Diesel Switchyard Locomotives 

Class I line haul operations typically account for the majority of fuel consumed and emissions 

when preparing locomotive inventories. As such, resources should be focused on developing 

emission estimates for these operations relative to other rail-related operations. However, for 

some local areas, certain operations related to switchyard activity may also be important. 

For Class I line-haul locomotives, emissions are normally calculated by multiplying the amount 

of fuel consumed in the inventory area by pollutant-specific emission factors. This calculation is 

performed for each railroad. The results for each railroad are then summed to obtain the total 

Class I railroad emissions in the inventory area.

For Class I line haul, Pechan obtained 2007 emission estimates from the Eastern Regional 

Technical Advisory Committee (ERTAC, 2010a). ERTAC used the Federal Railroad 

Administration’s GIS data to construct a dataset of link-level million gross tons per mile (MGT). 

Next the Railroad Fuel Consumption Index (RFCI) value was calculated for each railroad, which 

represents the number of GTM produced per gallon of diesel fuel. When applied to each link’s 

GTM per year, link-based fuel consumption can be calculated. This methodology allows for a 

more accurate reflection of how GTM are actually concentrated across rail line route miles. 

Finally, the fuel consumed is multiplied by the various emission factors derived for each Class I 

rail line to determine link-level emissions for each pollutant. An important aspect is determining 

the fraction of locomotives that fall under each regulatory “Tier,” since each Tier has an 

increasingly stringent emission rate for pollutants of concern. 

A limitations of the link-level MGT data maintained by the FRA is that the data are proprietary 

and can only be publicly released with the express permission of each Class I railroad. In 

addition, when the FRA coded the link-level MGT data they did not provide a means for 

separating out individual MGT contributions for links that are operated by multiple railroad 

companies. As such, some assumptions were made for these contributions by ERTAC. 

Class II/III line haul emissions were also developed and distributed by ERTAC (ERTAC, 

2010b). Limited documentation has been developed to describe the procedures used by ERTAC 

to develop this inventory. Generally, fuel consumption for all Class II/III railroads was obtained 

from the American Shortline and Regional Railroad Association and assigned to counties using 

route miles by rail line within each county. An average fuel use factor expressed in gallons per 

mile was then multiplied by the route miles to estimate fuel consumption by railroad and by 

county. Class II/III locomotives were all assumed to be uncontrolled with respect to emission 

rates used for estimating pollutant emissions. Class II/III rail emissions represent calendar year

2008, and as such were back-cast to 2007 using a surrogate growth indicator. A SESARM 

regional growth factor of 1.438 was developed using 2007 and 2008 total distillate fuel 

sales/deliveries to railroad consumers which were obtained from the DOE Energy Information 

Administration State Energy Data (DOE, 2009a). 

Passenger and commuter rail line emissions from EPA’s 2002 NEI were grown to 2007. For 

both categories, the growth factor was developed using 2002 and 2007 passenger/commuter fuel 

use data obtained from the DOE Transportation Energy Data Book (DOE, 2009b). For 

passenger rail operations, the growth factor value was 0.732. For commuter rail operations, a 

growth factor of 1.11 was used. 

Finally, the draft switchyard inventory was completed by ERTAC on June 4, 2010 (ERTAC, 

2010c). This inventory was compiled at a railyard level by ERTAC, but was summed to a 

county level for use in the SEMAP 2007 inventory. Documentation describing the specific 

procedures used is not available to date. We are providing an electronic file that provides 2007 

emissions at a railyard level, so that SESARM agencies can review the data that form the basis of 

the county-level estimates, and make revisions at that level as needed. 

Some state data were provided for the locomotive category. These data are summarized in 

Table III-7. North Carolina provided a statewide passenger rail inventory for 2007. Davidson 

County provided a county level inventory comprised of Class I line haul and switchyard activity, 

reported under the general SCC 2285000000. Shelby County provided an updated Class I line 

haul, passenger, and yard locomotive inventory for most pollutants. Any needed pollutant 

augmentation is described in Table III-7. 

E. QA/QC PROCEDURES 

Pechan performed the following quality assurance procedures on the final 2007 nonroad sector 

inventory. 

For the NONROAD/NMIM categories, Pechan quality assured all NCD updates provided by 

states to ensure consistency with the NCD formats, and for reasonableness. Where questions 

came up, we coordinated with the appropriate state/local agency. Cross-checks were performed 

to confirm that state-supplied revisions were correctly incorporated into the NCD. Pechan 

compared results with 2007 emission estimates prepared by EPA using a prior version of the 

NCD. These comparisons were performed to ensure that results changed as expected given the 

updates made by specific states to the NMIM inputs.

 46 Final Report

Pechan compiled records for the SESARM region from EPA’s NEI for aircraft, CMV, and 

passenger/commuter rail, and obtained Class I and Class II/III line haul, and railyard emission 

estimates from ERTAC. Pechan performed and quality assured any needed adjustments to year 

2007 (i.e., correct application of growth or backcast factors). Cross-checks were also performed 

to verify that state-supplied emission estimates were correctly incorporated into the draft 

inventory. Pechan also calculated missing pollutants for SCC-level state emission estimates, 

where emission factors or emission ratios were available. 

Emission estimates were converted into EPA’s NIF3.0 as a final deliverable. For the NMIM 

categories, commercial marine, and locomotive, separate database files were prepared for each 

subsector following EPA’s NIF3.0 nonpoint format. Aircraft emission estimates were prepared 

in EPA’s NIF3.0 point source format. EPA’s NIF QA Checker program was then run on these 

final files, and any referential integrity issues and invalid codes were identified and corrected. 

Finally, data source codes as described in Table III-8 were added to the NIF3.0 files to represent 

the source of the SCC, county-level emissions data for the final inventory.

B. NONROAD MOBILE SOURCE EMISSIONS 

Table IV-7 provides a summary of final 2007 nonroad mobile annual emissions by the four 

major nonroad subsectors for the SESARM region. PM-10 and PM-2.5 emissions represent 

primary PM, and are reported as PM10-PRI, and PM25-PRI. The commercial marine category is 

the most significant contributor regionally to SO2 emissions. Nonroad model categories account 

for the large majority of emissions for NOx, VOC, PM10-PRI, PM25-PRI, and CO. 

Table IV-8 presents a summary of the final annual NONROAD model emission estimates by 

state, as well as the percent contribution of each state to total regional emissions. Similar 

summaries providing 2007 annual state-level emission estimates for aircraft, commercial marine, 

and locomotives, as well as the percent contributions, are shown in Tables IV-9, IV-10, and 

IV-11, respectively. 

Since development of the draft inventory, locomotive switchyard emissions developed by 

ERTAC have been added. These emission estimates were developed at a railyard level, and 

summed to the county level for the 2007 SEMAP inventory. As mentioned in Section III.D, we 
PECHAN June 2010 

 53 Final Report

are providing an electronic file that provides emissions at a railyard level, so that SESARM 

agencies can review the data that form the basis of the county-level estimates, and make any 

needed revisions. In addition, for the aircraft category, EPA made some additions to the 2008 

military aircraft NEI that formed the basis of the initial draft SEMAP inventory. As discussed in 

Section III.B, we are distributing an electronic file showing additional emission records 

calculated by EPA for military aircraft by airport for the SESARM region. Agencies should 

provide feedback as to whether these records should be added to their inventory.

APPENDIX A. POINT SOURCE SUBTRACTION PROCEDURE 

DETAILS 

This Appendix describes source category-specific details on the point source subtraction 

procedures, and displays the area SCC to point SCC crosswalk (see Tables A-1 through A-8). 

A. ICI FUEL COMBUSTION 

To assist in the point source subtractions for industrial, commercial, and institutional (ICI) fuel 

combustion, Pechan developed two crosswalks: one between each Industrial fuel combustion 

area SCC and associated point SCCs (Table A-1), and an analogous crosswalk developed for 

Commercial/Institutional fuel combustion (Table A-2). 

Because natural gas consumed as pipeline fuel is not included by the Energy Information 

Administration (EIA) in EIA’s state energy consumption data for the Industrial sector, it was 

necessary to exclude pipeline natural gas combustion emissions from the point source subtraction 

procedure. Since there are no SCCs specific to pipeline natural gas combustion, point source 

pipeline natural gas combustion emission estimates were compiled by summing emissions for 

industrial sector natural gas internal combustion engine records (SCC 202002xx) with a pipelinerelated Standard Industrial Classification (SIC) or North American Industrial Classification 

System (NAICS) code (SIC codes 1311, 1321, 1381, 4612, 4613, 4619, 4922, 4923, 4924, 4925, 

or 4931; NAICS codes 211111, 21112, 22121, 221210, 486110, 48621, 486210, 486910, 48699, 

or 486990). 

B. CONSTRUCTION DUST 

Table A-3 displays the point SCCs associated with dust from Construction activities. These 

SCCs do not provide information to separate activity into the two area source category processes: 

 2311010000 - Construction: SIC 15-17; Residential; Total; and 

 2311020000 - Construction: SIC 15-18; Industrial/Commercial/Institutional; Total. 

Pechan apportioned point source construction dust emissions between the two categories using 

state-level acreage data reported in the EPA October 2008 report “Economic Analysis of Final 

Effluent Limitation Guidelines and Standards for the Construction and Development Industry” 

(EPA, 2009a). These proportions for each SESARM state are displayed below.

C. SOLVENT UTILIZATION 

Table A-5 presents the point source crosswalk for each solvent utilization nonpoint SCC. This 

crosswalk was derived from the crosswalk used in performing VOC emissions-based point 

source subtractions for the 2002 NEI. As noted in the Table A-5 crosswalk, two area source 

solvent utilization SCCs (2401005000-Auto Refinishing and 2401070000-Motor Vehicles) are 

associated with the same point SCCs. For the Auto Refinishing area source category, point 

source subtractions for the listed SCCs were limited to records identified with Auto Refinishing 

industry sector SIC/NAICS codes (e.g., NAICS code 8111*). Emissions for all other applicable 

point SCC state/local inventory records were subtracted from total emissions for the Motor 

Vehicles source category. 

D. GASOLINE DISTRIBUTION 

Table A-6 displays the point SCCs associated with gasoline distribution. Some of these SCCs do 

not provide information to separate activity into each area source stage I gasoline distribution 

filling technology. Therefore, Pechan allocated the emissions from these point SCCs to each 

filling technology based on the proportion of emissions from Pechan’s default inventory.
