Dear Mr. Brooks: 

www.dn r.mo.gov 

The Missouri Department of Natural Resources requests that the U.S. Environmental Protection 

Agency (EPA) amend the Missouri State Implementation Plan (SIP) to incorporate the following 

enclosed plan: 

Early Progress Plan for the Missouri Portion of the St. Louis Nonattainment Area for the 2008 

Ground-Level Ozone National Ambient Air Quality Standard. 

Pursuant to Section 176( c) of the Clean Air Act, this SIP revision establishes transportation 

conformity motor vehicle emission budgets for Missouri's portion of the St. Louis nonattainment 

area under the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). The St. 

Louis nonattainment area was designated a marginal nonattainment area for the 2008 8-hour 

ozone NAAQS on May 21,2012. The new motor vehicle budgets are based on a demonstration 

that emissions are steadily decreasing in the St. Louis area as a result of existing permanent and 

enforceable control measures in the area. Although the St. Louis nonattainment area currently 

has approved motor vehicle emission budgets that have been used to demonstrate conformity 

under the 1979 I-hour and 1997 8-hour ozone NAAQS, the new budgets established in this plan 

are needed due to the recent transition from an older on-road mobile source emissions model, 

Mobile 6, to the current on-road mobile source emissions model, MOVES. 

The commission adopted the enclosed plan action on March 28, 2013 after considering program 

staff testimony at the public hearing. Two written comments were received from the U.S. 

Environmental Protection Agency (EPA) during the public comment period. A compilation of 

EPA's comments and Missouri's responses are enclosed. The commission has full legal 

authority to develop the SIP pursuant to Section 643.050 of the Missouri Air Conservation Law. 

The state followed all applicable administrative procedures in proposing and adopting the plan 

action. Enclosed are the required SIP submittal elements for determination of plan completeness 

per 40 CFR Part 51 , Appendix V. 

In order to comply with Attachment A of the "Regional Consistency for the Administrative 

Requirements of State Implementation Plan Submittals and the Use of Letter Notices" memo 

dated April 6, 2011, a searchable pdf version of this document will be emailed to the EPA

EXECUTIVE SUMMARY 

This early progress plan provides the basis for establishing early transportation conformity motor 

vehicle emission budgets for Missouri’s portion of St. Louis nonattainment area under the 2008 

ozone National Ambient Air Quality Standard (NAAQS), herein referred to as the St. Louis 

nonattainment area. The Missouri portion of the St. Louis nonattainment area consists of the 

counties of Franklin, Jefferson, St. Charles, and St. Louis and the City of St. Louis. The St. 

Louis nonattainment area is currently classified as moderate under the 1997 ozone NAAQS and 

was designated marginal for the 2008 ozone NAAQS on May 21, 2012. As a marginal 

nonattainment area, the attainment date for the 2008 ozone NAAQS is December 31, 2015. 

The U.S. Environmental Protection Agency’s (EPA’s) transportation conformity rule allows 

states to submit an early progress plan containing early motor vehicle emission budgets for a 

nonattainment area in advance of a state implementation plan (SIP) addressing all other 

applicable Clean Air Act requirements (Sections 172(c) and 182(a) for marginal areas) (69 FR 

40019, July 1, 2004). Early budget submittals are to be based on a level of emissions that 

demonstrates progress toward attainment of the NAAQS. For purposes of this early progress 

plan for the the St. Louis nonattainment area, progress toward attainment of the 2008 ozone 

NAAQS is demonstrated if projected emissions by the December 31, 2015 attainment date are 

significantly less than emissions in the 2008 base year. This plan is not required or intended to 

demonstrate attainment of the NAAQS; a separate SIP revision will be submitted at a later time 

for the 2008 ozone NAAQS addressing all other requirements in Sections 172(c) and 182(a) of 

the Clean Air Act. 

This early progress plan establishes a 2008 baseline emissions inventory for the St. Louis 

nonattainment area for ozone precursors—carbon monoxide (CO), oxides of nitrogen (NOX), and 

volatile organic compounds (VOC)—and projects the emissions for these pollutants to the 

attainment year of 2015. This plan demonstrates that emissions are decreasing over the 2008-

2015 time period as a result of permanent and enforceable federal and state control requirements 

already in place in the St. Louis nonattainment area. It also establishes motor vehicle emission 

budgets for VOC and NOx for the Missouri portion of the St. Louis nonattainment area 

consistent with emissions levels that provide steady progress toward attainment of the 2008 

ozone NAAQS. Although CO is an ozone precursor, transportation conformity regulations only 

apply to VOC and NOx in ozone nonattainment areas. The new motor vehicle emissions budgets 

for 2015 are summarized in the chart below.

St. Louis Ozone Nonattainment Area (Tons per Ozone Season Day) 

Pollutants 2015 Budgets (tons/ozone season day) 

NOX 76.70 

VOC 32.70 

The new motor vehicle emission budgets established in this early progress plan are intended to 

be used in regional transportation conformity demonstrations with the 2008 ozone NAAQS. 

Although the St. Louis nonattainment area has approved motor vehicle emissions budgets that 

have been used under the previous ozone standard, new budgets are needed due to EPA’s recent 

transition from an older on-road mobile source emissions model (Mobile6) to the current model 

(MOVES).

1. Background and Purpose 

1.1 National Ambient Air Quality Standard for Ozone 

Congress first enacted the Clean Air Act (CAA) in 1970. It was last amended in 1990. The 

CAA requires EPA to set NAAQS for pollutants considered harmful to public health and the 

environment. There are two categories of NAAQS. The primary standards are designed to 

establish limits to protect public health, and the secondary standards are intended to protect 

against environmental and welfare effects such as decreased visibility, and damage to crops, 

animals, and buildings. Currently there are six pollutants with established primary level 

NAAQS: carbon monoxide, lead, particulate matter, sulfur dioxide, nitrogen dioxide, and ozone. 

These pollutants are referred to as “criteria” pollutants. If an area is found to violate one of these 

standards, it is classified as a nonattainment area for that specific pollutant. The states and/or 

tribes responsible for the affected area must then develop and carry out strategies and measures 

to attain the NAAQS. The goal is for any areas designated as “nonattainment” to be reclassified 

by the EPA to attainment for the pollutant. 

The 1-hour ozone NAAQS was established in 1979. Under this standard, the ozone threshold 

value was 120 parts per billion (ppb), measured as a 1-hour average concentration. An area met 

this ozone NAAQS if there were no more than three exceedances at any one monitor in the 

region in a three year period. 

The CAA requires that the EPA carry out a periodic review of NAAQS for the criteria pollutants. 

The EPA reviewed the 1-hour NAAQS for ozone in the 1990’s and determined based on the 

latest health studies that a new standard was needed to ensure protection of public health. The 

new standard of 80 ppb was finalized in July of 1997. The 1997 ozone standard is based on an 

eight-hour averaging period. A violation occurs when the three-year average of the annual 

fourth highest daily maximum 8-hour ozone concentration is less than or equal to the NAAQS (a 

level of 85 ppb due to the rounding convention). 

As a result of their next periodic review of the ozone NAAQS, EPA again determined the 

NAAQS was not adequately protecting public health and issued a new ozone standard in March 

2008. The 2008 NAAQS uses the same 8-hour averaging scheme as the 1997 ozone standard, 

but lowers the standard from 80 ppb to 75 ppb. 

1.2 Ozone and Its Formation 

Ozone is a reactive chemical compound. It is made up of three oxygen atoms and is identified 

by the chemical symbol O3. Ozone is a gas that occurs both in the Earth’s upper atmosphere and 

at ground level. When it occurs naturally in the upper atmosphere, ozone acts as a shield from 

the sun’s harmful ultraviolet rays. However, ozone that forms at ground-level is a concern. 

Elevated ground-level ozone concentrations can be harmful to humans if breathed. Breathing 

ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, 

and congestion. It can worsen bronchitis, emphysema, and asthma. Ground-level ozone also can 

reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently 

scar lung tissue. 
3 

Unlike most other pollutants, ozone is not emitted directly into the air by specific sources, but is 

formed by a photochemical reaction. This reaction occurs between NOx and VOCs in the 

presence of sunlight and elevated ambient temperatures. CO also plays a role in the complex 

chemical reactions. Because sunny, hot conditions are necessary, ground-level ozone forms in 

much higher concentrations during the summer months. Ozone is most commonly an urban air 

issue, but high ozone readings can also be found in rural areas. This is because emissions of 

NOx and VOC from motor vehicles and stationary sources can be carried hundreds of miles from 

their origins, and contribute to high ozone concentrations over large, multi-state regions. 

There are numerous sources of NOx and VOC pollutants including both anthropogenic and 

natural sources. Anthropogenic sources can be further broken down into four separate source 

categories: point sources, area sources, on-road mobile sources, and off-road mobile sources. 

Point sources include larger permitted industries and power plants. Area sources are small, 

stationary, non-transportation sources that collectively as a group can have a significant 

contribution to air pollution. Examples of area sources include gas stations, automotive shops 

and dry cleaners. The on-road mobile source category includes cars, trucks and buses, and offroad sources include trains, ships, boats, airplanes, lawn equipment, and construction equipment. 

Natural sources, including biogenic releases from vegetation, lightning, soil, and decomposition, 

are not considered in this document due to the difficulties in quantifying and controlling them. 

1.3 Description of the St. Louis Nonattainment Area 

EPA’s final rule designating nonattainment areas and associated classfications for the 2008 

ozone NAAQS was published in the Federal Register on May 21, 2012 (77 FR 30088). The 

entire state of Missouri was designated attainment/unclassifiable except the St. Louis-St. 

Charles-Farmington, MO-IL Area, which was designated as a marginal nonattainment area. 

Figure 1 provides a map of the bi-state marginal ozone nonattainment area under the 2008 ozone 

NAAQS. The following is a list of the counties contained in the St. Louis Missouri-Illinois 8-

hour ozone marginal nonattainment area for the 2008 ozone NAAQS: 

 St. Louis County, MO 

 St. Louis City, MO 

 St Charles, MO 

 Jefferson County, MO 

 Franklin County, MO 

 Madison County, IL 

 St. Clair County, IL 

 Monroe County, IL 

Concurrent with the designation rule, EPA released an additional final rule that established 

attainment dates and revoked the 1997 ozone standard for transportation conformity purposes (77 

FR 30160, May 21, 2012). This rule sets an attainment date of December 31, 2015 for the St. 

Louis marginal nonattainment area under the 2008 ozone standard.

1.4 Transportation Conformity 

Transportation conformity is required under CAA section 176(c) (42 U.S.C. 7506(c)) to ensure 

that federally funded or approved highway and transit activities are consistent with (“conform 

to”) the purpose of the state air quality implementation plan (SIP). “Conform to” the purpose of 

the SIP means that transportation activities will not cause or contribute to new air quality 

violations, worsen existing violations, or delay timely attainment of the relevant NAAQS or any 

interim milestones. Transportation conformity applies to designated nonattainment and 

maintenance areas for transportation-related criteria pollutants: ozone, PM2.5, PM10, carbon 

monoxide, and nitrogen dioxide. EPA’s transportation conformity rule (40 CFR Parts 51 and 93) 

establishes the criteria and procedures for determining whether metropolitan transportation plans 

(TIPs) and federally supported highway and transit projects conform to the SIP. 

CAA section 176(c)(6) and the conformity regulation at 40 CFR 93.102(d) provide a one-year 

grace period from the effective date of designations before transportation conformity applies in 

areas newly designated nonattainment for a specific NAAQS. Transportation conformity for the 

2008 ozone NAAQS applies one year after the effective date of nonattainment designations for 

this NAAQS, i.e., July 20, 2013. EPA’s final rule for determining area 

designations/classifications under the 2008 ozone NAAQS also revoked the 1997 ozone NAAQS 

for transportation conformity purposes. This revocation is effective one year after the effective 

date of designations for the 2008 ozone NAAQS (July 20, 2013). Therefore, transportation 

conformity for the 1997 ozone NAAQS is no longer required starting on that date. This 

revocation date also corresponds with the end of the one-year conformity grace period for the 

2008 ozone NAAQS. This action was taken by EPA to bring certainty to the transportation 

planning process in ozone nonattainment and maintenance areas. EPA stated that no backsliding 

will result from the revocation for purposes of transportation conformity, as areas designated 

nonattainment for the 2008 ozone NAAQS will be required to use any existing adequate or 

approved SIP motor vehicle emissions budgets (“budgets”) for a prior ozone NAAQS when 

determining conformity for the 2008 ozone NAAQS until budgets for the 2008 ozone NAAQS 

are either found adequate or are approved. 

In 2010, EPA released the Motor Vehicle Emissions Simulator (MOVES) version 2010 (75 FR 

9411, March 2, 2010). With EPA’s official release of MOVES they also granted a two-year 

grace period for when MOVES would be required to be used in transportation conformity 

determinations. Then in February 2012, EPA extended the MOVES transitional grace period 

until March 2, 2013 (77 FR 11394, February 27, 2012). 

MOVES is a completely redesigned model, not just an updated version of the previous mobile 

model called Mobile6. The way MOVES calculates emissions changed to reflect EPA’s current, 

more accurate understanding of the emissions produced by vehicles and the various factors that 

affect the emissions. NOX emissions from MOVES are significantly higher when compared 

Mobile6 because of the larger portion that extended idling of heavy duty vehicles contributes to 

the emissions total. VOC emissions calculated with MOVES are slightly higher but generally 

comparable to VOC emissions calculated with Mobile6. 
6 

St. Louis currently uses approved mobile emissions budgets for NOx and VOC that were 

included in the maintenance plan for the area under the 1979 1-hour ozone standard. These 

budgets were established in 2002 and have been used to demonstrate conformity under the 1997 

ozone NAAQS. These budgets were created using Mobile6, the previous on-road mobile source 

emission model. As stated above, EPA’s new on-road mobile source emission model, MOVES, 

will be required to be used to demonstrate conformity for any conformity determinations that 

start after March 2, 2013. Because the two models are very different in their calculation of 

emissions and emissions are generally higher when using MOVES (particularly NOx emissions), 

it would be difficult to demonstrate conformity in an analysis that compares MOVES emissions 

to motor vehicle budgets based on Mobile6. 

1.5 Early Progress Plan Purpose 

This early progress plan was developed to establish motor vehicle emission budgets to be used in 

regional transportation conformity determinations for the Missouri portion of the St. Louis 

nonattainment area under the 2008 ozone NAAQS. Although the St. Louis nonattainment area 

has approved motor vehicle emissions budgets that have been used under the previous ozone 

standard, new budgets are needed due to EPA’s recent transition from an older on-road mobile 

source emissions model (Mobile6) to the current model (MOVES). 

The plan demonstrates progress towards attainment of the 2008 ozone NAAQS based on a 

comparison of ozone precursor emissions (CO, NOx, VOC) in the base year of 2008 and the 

attainment year of 2015. This analysis shows that substantial reductions in emissions are 

expected to occur over the 2008-2015 time period in the St. Louis nonattainment area as a result 

of state and federal control requirements that are in place in the area. The new NOX and VOC 

motor vehicle emission budgets established in this plan are consistent with emissions levels that 

provide steady progress toward attainment of the 2008 ozone NAAQS. Although CO is an 

ozone precursor, transportation conformity regulations only apply to VOC and NOX in ozone 

nonattainment areas.

2. Demonstration of Progress towards Attainment – Development and 

Comparison of Emissions Inventories for 2008 and 2015

For the purposes of this early progress plan, progress towards attainment is demonstrated if 

projected emissions by the December 31, 2015 attainment date are significantly less than 

emissions in the 2008 base year. In order to meet these requirements, the Air Program has 

developed a 2008 base year comprehensive emissions inventory for NOx, VOC and CO and 

projected the emissions inventory for these three pollutants to 2015 for the St. Louis 

nonattainment area. Both the 2008 and the 2015 emissions inventories include all point, area, 

on-road mobile, and off-road mobile source categories. 

2.1 2008 Base Year Emissions 

This section provides a brief description of the methods used to develop the 2008 base year as 

well as a summary of the emissions. More detailed documentation of the development of the 

emissions inventories for point, area, on-road mobile, and off-road mobile categories are in 

Appendix A and Appendix C. 

Point source emissions for the pollutants of concern were compiled from Missouri’s Air 

Emissions Inventory System (MOEIS) Database based on annual emissions reports submitted by 

permitted facilities. Area source emissions were calculated using the most recently available 

methodologies and emissions factors from U.S. EPA along with activity data (typically 

population, employment, fuel use, etc.) specific to 2008, except for stage II refueling emissions 

for on-road motor vehicles, which were calculated with MOVES 2010a and account for the stage 

II controls that were in place in the St. Louis nonattainment area in 2008. On-road mobile source 

emissions were also developed using MOVES 2010a. The key inputs used in the MOVES model 

are as follows: vehicle age distributions based on registration data from Missouri’s Department 

of Revenue, vehicle miles traveled (VMT) information from East-West Gateway, and controls 

including the Gateway Vehicle Inspection Program (GVIP) and reformulated gasoline. The 

2008 VMT data is summarized in Table 1. Off-road mobile source emissions other than 

emissions from aircraft, marine engines, and locomotives were calculated using the NONROAD 

2008a model using primarily EPA default inputs from the National County Database. Emission 

estimates for aircraft, marine engines, and locomotives were calculated using EPA 

methodologies, emission factors, and activity data specific to 2008. The outputs from the 

NONROAD 2008a model were added to the emission estimates for aircraft, marine engines, and 

locomotives to get the total off-road mobile source emissions for the Missouri portion of the St. 

Louis nonattainment area.

Totals 21,625,062,385 

The 2008 emissions are in tons/ozone season day. In order to calculate the emissions in 

tons/ozone season day, the Air Program followed the methods summarized briefly here and 

described in greater detail in Appendix C. For point sources, ozone season day emissions are 

calculated on the Emissions Inventory Questionnaire (EIQ) form 2.0Z, Ozone Season 

Information. On this form, the facility-reported maximum daily throughput during the ozone 

season is multiplied by the pollutant emission factor and reduced by a control efficiency (if 

applicable) to reach the ozone season daily emissions. For area sources, ozone season day 

emissions were calculated from the Emissions Modeling Clearinghouse (EMCH) temporal 

allocation profiles that are Source Classification Code (SCC)-specific. These temporal profiles 

were applied for a typical Tuesday in July. See Appendix C-7 for the temporal allocation 

method, calculation tables and an example. Off-road mobile source ozone season day emissions, 

other than aircraft, marine engine, and locomotive emissions, were calculated using NONROAD 

2008a, and additional information can be found in Appendix C-4. Off-road mobile source ozone 

season day emissions from aircraft, marine engines, and locomotives were developed by 

converting annual emissions to ozone season day emissions using SCC specific EMCH temporal 

allocation profiles for a typical Tuesday in July. For onroad mobile sources, the month level was 

selected for the timing parameter in the emissions output detail options in MOVES2010a in order 

to get total emissions for each month for the entire year. The emissions from the months of April 

through October were totaled, then divided by 214, the number of days in those months, to give 

average ozone season day emissions. Table 2 below shows the ozone season day CO, NOX, and 

VOC emissions from all four source categories for the Missouri portion of the St. Louis 

nonattainment area for 2008.

Off-Road Mobile Sources 527.74 65.18 45.08 

Total 1,171.61 321.79 223.42 

2.2 Control Measures 

To project emissions from 2008 to 2015, the Air Program relied on growth factors and control 

measures where applicable. The control assumptions are based on measures implemented after 

the 2008 base year and in place in the St. Louis area in 2015. This section describes the controls 

assumed in the future year of 2015; more information on the development of the 2015 inventory 

is in section 2.3. 

The main control measures that were relied upon in this document are federal motor vehicle 

standards for on-road and off-road mobile sources, including EPA’s heavy-duty diesel engine 

standards, Tier 2 motor vehicle standards, and Tier 4 offroad engine standards. These control 

measures and the continued phase out of older higher polluting mobile sources are incorporated 

into the MOVES and NONROAD models that were used to develop both the base and future 
9 

year mobile source emissions inventories. In addition to federal motor vehicle standards; 

reformulated gasoline requirements and the GVIP were also included in the modeling when 

developing both the base and future year on-road mobile source inventories. 

For point sources, the main control measure relied upon is the Clean Air Interstate Rule (CAIR) 

for NOx emissions from power plants. CAIR covers 27 eastern states and the District of 

Columbia. The rule uses a cap and trade system to reduce the target pollutants—sulfur dioxide 

(SO2) and NOx—by 70 percent. There are four Ameren power plants affected by this rule in the 

Missouri portion of the St. Louis nonattainment area. Although court decisions have remanded 

CAIR and its replacement, the Cross State Air Pollution Rule (CSAPR), to EPA, CAIR remains 

in place until a valid replacement rule is developed and is considered to be permanent and 

enforceable (November 19, 2012 memo from Gina McCarthy, EPA Assistant Administrator). 

Another adjustment was made to account for a consent agreement between the Air Program and 

MEMC Electronics Materials Incorporated for the company to continue to operate their 

scrubbers for the control of NOX from their acid bath/etching process. 

It should be noted that the emissions projections included in this plan do not reflect the 

reductions expected from a range of measures being implemented to reduce diesel emissions, 

including NOx, in the St. Louis nonattainment area. These measures have been funded through 

sources such as the: 

 U.S. EPA’s Midwest Clean Diesel Initiative 

 Congestion Mitigation and Air Quality Improvement (CMAQ) Program 

 Diesel Emissions Reduction Act (DERA) 

 American Recovery and Reinvestment Act of 2009 

 Heavy Duty Diesel Idling Rule, 10 CSR 10-5.385

 Various supplemental environmental projects 

 

These projects include the installation of particulate filters, diesel oxidation catalysts, and closedcrankcase ventilation systems, on school buses, over-the-road trucks, and municipally-owned 

utility vehicles. These projects also include upgrading diesel construction engines, locomotive 

engines, and marine engines with engines meeting more stringent emissions standards. These 

projects also include the installation of idle reduction technology on school buses, long-haul 

trucks, and locomotives. It is anticipated that DERA and CMAQ funding will continue to 

support additional diesel emissions reduction projects in the near future, which will contribute to 

further progress towards attainment of the 2008 ozone NAAQS. 

In addition, there are several other federal control measures that have recently been proposed or 

promulgated that are not accounted for in the plan but are expected to reduce the amount of NOX

and VOC emissions in the St. Louis nonattainment area. The control measures expected to have 

the greatest effect on NOX and VOC emissions in the St. Louis area include National Emission 

Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and 

Institutional Boilers and Process Heaters (Boiler MACT), mercury and air toxics standards for 

power plants (MATS), improved motor vehicle fuel efficiency standards, and the phase in of tier 

4 emission standards for off-road engines. The Boiler MACT and the MATS were both written 

to address hazardous air pollutants, and will therefore have the greatest reductions in pollutants 
10 

such as mercury, acid gases, and PM2.5. However, if owners of boilers and EGUs subject to 

these new rules decide to improve plant efficiency or switch to cleaner fuels for compliance 

strategies, then co-benefits for NOX and VOC emissions are expected for these sources. The Air 

Program did not rely on any of these recently promulgated or proposed rules when developing 

the future year emissions inventory; however the anticipated reductions from these new rules 

may also contribute to progress towards attainment of the 2008 ozone NAAQS in the St. Louis 

area. 

2.3 2015 Future Year Emissions 

This section describes the development of the 2015 future year emissions inventory. Unless 

otherwise noted below, the projected point and area source emissions in the St. Louis area for 

2015 were estimated using the 2008 base year inventory and growth factors appropriate for each 

source category. Growth factors were created from the Economic Growth and Analysis System 

(EGAS) version 5.0 model (http://www.epa.gov/ttnecas1/egas5.htm) using economic growth 

projections from the Policy Insight® Model for Regional Economic Model, Inc (REMI). Table 3 

summarizes the ozone season day CO, NOX, and VOC emissions from all four source categories 

for the Missouri’s portion of the St. Louis nonattainment area for 2015.

2.3.1 2015 Point Source Emissions 

To forecast point source emissions from 2008 to 2015, they were separated into electric 

generating units (EGUs) and all other point sources. The following two subsections briefly show 

how these two emission source categories were forecasted to 2015. Detailed information about 

the development of the point source inventories for the future year, 2015, can be found in 

Appendix B of this document. Table 4 shows the 2015 overall CO, NOx and VOC emissions for 

point sources (EGU & other point sources) for each county in the Missouri’s portion of the St. 

Louis nonattainment area.

2.3.1.1 2015 Point Sources Other Than EGUs

To forecast point source emissions to the future year of 2015, growth factors were obtained from 

the EGAS version 5.0, published in January 2006. The model forecasts economic activity to 

generate growth factors used to develop emission inventories. For this plan, growth factors were 

obtained for 2015 for the five counties of interest: Franklin (29071), Jefferson (29099), St. 

Charles (29183), St. Louis County (29189), and St. Louis City (29510). The default REMI 5.5 

(Regional Economic Model, Inc) configuration was used, and it includes growth based on 

economy, population, employment, consumption, and value-added for 53 major sectors of the 

economy. Factors were created for both point and area categories, and are broken out by SCC, 

county, and year. Point growth factors covered all point SCCs in use in Missouri for 2008. The 

county and SCC-specific growth factors were multiplied by the 2008 ozone season day 

emissions to get the 2015 forecast point source inventory. The following equation shows the 

general approach of forecasting 2008 point source emissions to 2015: 

Future Year Emissions (tons/ozone season day) = Base Year Emissions (tons/ozone season day) 

* Growth Factor 

An adjustment was also made for a consent agreement between the Air Program and MEMC 

Electronics Materials Incorporated for the company to continue to operate their scrubbers for the 

control of NOX from their acid bath/etching process. This consent agreement has been submitted 

to EPA for inclusion in Missouri’s SIP. Table 5 shows the 2015 point source (excluding EGUs) 

CO, NOx and VOC emissions for each county in the Missouri’s portion of the St. Louis 

nonattainment area.

2.3.1.2 2015 EGU Emissions 

The 2015 ozone season NOX emissions inventory for the four electric utilities in the Missouri 

portion of the St. Louis nonattainment area, Ameren’s Labadie, Meramec, Rush Island, and 

Sioux, were established using the actual average regulatory ozone season (May – September) 

NOX emissions from the Ameren units from 2008 - 2011. This four year average of regulatory 

ozone season NOX emissions was determined to be representative of the projected NOx 
12 

emissions in 2015 because of CAIR, which establishes allowances that limit emissions from 

electric generating units. For each ton of NOX emitted during the regulatory ozone season, one 

allowance must be surrendered. If a unit has excess allowances through CAIR after surrendering 

sufficient allowances to cover their emissions, they may bank the allowances to be used in a 

future year, or they can trade the allowances with other electric generating units included in 

CAIR. In 2015, the amount of allowances awarded to these four Ameren units each year under 

CAIR will be significantly lower than the current level of allowances they receive. However, it 

is likely that Ameren will have some banked allowances that they have been able to save from 

2009 – 2014 that will allow them to keep their emissions relatively constant for the first few 

years after the 2015 CAIR allocations take effect. These assumptions are why the 2008 – 2011 

four year average for ozone season NOX emissions was used as the conservative method to 

determine the projected emissions in 2015. Additional details regarding the development of the 

2015 average ozone season day NOX emissions from these four Ameren EGU facilities can be 

found in Appendix B. CO and VOC emissions from Ameren units were grown to 2015 using 

EGAS 5.0. Table 6 shows the 2015 EGU point source CO, NOx and VOC emissions for each 

county in the Missouri portion of the St. Louis nonattainment area.

2.3.2 2015 Area Source Emissions

Similar to the 2015 point source emission projections, the 2015 area source emissions projections 

were calculated using the 2008 area source emissions inventory and applying growth factors 

from EGAS 5.0 to project the emissions in 2015. The following equation shows the general 

approach of forecasting 2008 area source emissions to 2015: 

Future Year Emissions (tons/ozone season day) = Base Year Emissions (tons/ozone season day) 

* Growth Factor 

For area sources, stage II refueling VOC emissions for on-road motor vehicles were calculated 

using MOVES 2010b. The stage II controls in MOVES were “turned off” by setting the stage II 

control efficiencies in the countyyear input table to zero (0) for all counties in the Missouri 

portion of the St. Louis nonattainment area. This was done because the Air Program is currently 

using EPA’s final widespread use rule (77 FR 28772, May 16, 2012) and associated guidance to 

develop a SIP revision to remove stage II control requirements in the St. Louis area due to the 

widespread use of on-board vapor recovery systems. Although a date for phasing out the Stage 
13 

II vapor recovery program in St. Louis has not yet been established, the phase out is expected to 

start prior to 2015. Setting the stage II controls in MOVES to a 0 percent control efficiency in 

would accurately estimate vehicle refueling emissions if phase out of stage II vapor recovery 

equipment is complete at all gasoline dispensing stations in the area by 2015, and would 

conservatively estimate these emissions if the phase out is still underway at some stations.

2.3.3 2015 On-road Source Emissions 

On-road mobile source emissions for 2015 were developed using MOVES version 2010b and 

applying a 1.5 percent annual growth factor to the 2008 VMT and source type population data. 

Detailed information about the development of the 2015 off-road emissions inventory can be 

found in Appendix B of this document. 

The 1.5 percent growth rate was developed through a coordinated effort with MoDOT, Illinois 

Environmental Protection Agency, the Federal Highway Administration, Illinois Department of 

Transportation, and East-West Gateway. Table 8 shows the actual historical annual VMT on 

state owned roads for the Missouri Portion of the St. Louis nonattainment area. Since 1985, 

VMT growth has varied considerably for the Missouri side of the St. Louis nonattainment area 

ranging as high as 6.7 percent in 1988 and as low as negative 1.8 percent in 1991. The average 

annual growth rate since 1985 is 1.9 percent. However, the traffic demand model used by Eastwest Gateway predicts approximately 1 percent annual VMT growth for the next 10 years. The 

traffic demand model used by East-West Gateway uses current economic trends as a factor to 

calculate projected growth rates. With such extreme variations in a relatively short amount of 

time, it is not reasonable to project VMT to a future year solely considering current economic 

trends. Due to the worst economic downturn since the Great Depression, the economy has been 

struggling since 2008, which has resulted in lower projected VMT growth rates from the traffic 

demand model. 

On September 25, 2012, the Air Program discussed the use of the 1.5 percent growth rate to be 

used in this early progress plan with the Interagency Council of Governments (IACG) group 

responsible for transportation conformity in the St. Louis nonattainment area. Illinois EPA 

stated that this would be consistent with the growth rate that they used in their maintenance plans 

for the St. Louis area for both 1997 PM2.5 and 1997 Ozone NAAQS, and the members of the 
14 

IACG agreed that a 1.5 percent growth rate was reasonable to use for the purposes of this plan. 

This 1.5 percent growth rate was also applied to the source type population data because it is 

assumed that growth in VMT would not be the result of the same amount of cars on the road 

driving more, but rather an increase in the actual number of vehicles on the road with the average 

VMT per vehicle remaining constant. Table 9 summarizes the projected 2015 annual VMT used 

for each county in the Missouri portion of the St. Louis nonattainment area.

Other than VMT data and source type population data, the same data sets that were used to 

develop the 2008 MOVES inputs were also used to develop the 2015 MOVES inputs. 

It is noted that a different version of MOVES was used to establish the future year emissions in 

comparison to the base year emissions (i.e. MOVES 2010a vs. MOVES 2010b). The on-road 

motor vehicle emissions for 2008 were developed for a previous SIP action using MOVES 

2010a. The use of this data reduced the modeling resources required for this early progress plan. 

Version 2010b of MOVES is an update to version 2010a that increases the software’s 

functionality without significantly affecting the modeled emissions of criteria pollutants. EPA 

considers versions 2010a and 2010b to be the same model for SIP development purposes. 

Detailed information about the development of the 2015 on-road emissions inventory can be 

found in Appendix B of this document. 

Table 10 shows the ozone season day CO, NOX, and VOC emissions from the on-road mobile 

source category for the Missouri portion of the St. Louis nonattainment area for 2015. The 

figures in the table assume the continued use of reformulated gasoline, the continued phase-in of 

the Tier 2 motor vehicle emissions standards, and the continuing operation of GVIP.

2008a model. The NONROAD 2008a model also includes control factors for federal controls 

that have been promulgated. Aircraft, marine engine, and locomotive emissions were grown 

from the 2008 inventory using EGAS growth factors. The outputs from the NONROAD 2008a 

model were added to the emission estimates for aircraft, marine engines, and locomotives to get

Table 12 provides a comparison of ozone season day emissions for the years 2008 and 2015. 

The table shows the differences by source category along with the total changes in emissions for 

each pollutant listed. As shown in the table, CO, NOX, and VOC emissions within the 

nonattainment area are expected to decrease significantly between 2008 and 2015. Based on 

these emissions trends of CO, NOX, and VOC, it is demonstrated that progress will be made 

towards attainment of the 2008 ozone NAAQS.

*Note: A negative value indicates a projected decrease in emissions from 2008 to 2015. 

A positive value indicates a projected increase in emissions from 2008 to 2015. 

It should be noted that the projected increase in VOC emissions for area sources are based on 

(EGAS) growth factors. Due to the use of these growth factors, emissions of VOC from area 

sources are projected to increase significantly by 2015. However, these projected increases are 

likely overstated and actual area source emissions of VOC are not expected to increase as much 

as the growth factors suggest. EPA’s Regulatory Impact Analysis (RIA) for the 2006 PM 

NAAQS rule, Appendix D (http://www.epa.gov/ttn/ecas/regdata/RIAs/Appendix%20D--

Inventory.pdf), notes on pages D-29 to D-36, that though REMI data was used in their emission 

forecasting method, the oversimplification of emissions growth based on economic factors likely 
17 

overestimates projected emissions. EPA’s recognition of the downward trend in emissions 

during times of economic growth supports the conclusion that the VOC increases for area 

sources are likely an artifact of the growth methodology. From page D-36: 

“While it is not clear that all of the factors that have served to produce this historical 

decline will continue to operate in the future, it appears unreasonable to assume that we 

currently have arrived at an ‘inflection point’ past which the trend will stop or reverse 

itself. Indeed, because the available data show that a number of large sources in the 

sectors of interest have no or limited pollution controls, it is reasonable to expect 

emissions rates will be steady or decline. Continuing to ignore this factor in future-year 

emission projections may increasingly skew the predicted emissions increase, and the 

farther into the future the forecast the more dramatic the impact. The preceding and 

other explanations suggested that we need to reevaluate our emission forecasting 

approaches for stationary non-EGU sources to incorporate factors not adequately 

considered in past methodologies.”

The projected decreases in CO, NOX and VOC emissions from 2008 to 2015 are primarily due to 

decreases in the mobile source categories. Average ozone season daily CO, NOX and VOC 

emissions in the St. Louis area from on-road and off-road mobile sources are projected to 

decrease approximately 323.61 tons/day, 96.01 tons/day and 42.57 tons/day, respectively. That 

amounts to over 29% reduction of mobile source CO emissions, 42% reduction of mobile source 

NOX emissions and 40% reduction of mobile source VOC emissions. Point and area source CO 

and NOX emissions are expected to remain relatively stable, and point and area source VOC 

emissions are projected to increase slightly. The overall CO, NOx and VOC emissions 

reductions from 2008 to 2015 are 27%, 31% and 12%, respectively.

3. Transportation Conformity and Motor Vehicle Emission Budgets

This section establishes new VOC and NOX motor vehicle emissions budgets for the 2015 

attainment year to be used for transportation conformity purposes in the St. Louis nonattainment 

area once EPA finds the budgets adequate. The budgets are set based on the onroad mobile 

source emissions in 2015 and are consistent with an overall level of emissions that assures 

progress toward attainment of the 2008 ozone NAAQS. These budgets were developed using 

MOVES 2010b. Section 2 of this document explains the methods used to develop these budgets, 

and Appendix B contains all data that was used to develop the inputs to MOVES 2010b to create 

these budgets. 

In the Missouri portion of the St. Louis nonattainment area, transportation conformity for the 

2008 ground-level ozone NAAQS will be based on these submitted motor vehicle budgets after 

EPA determines that the budgets meet the adequacy criteria of the transportation conformity rule. 

Once these budgets are found adequate by EPA, the motor vehicle emissions budgets established 

for the 1-hour ozone NAAQS will no longer be used for conformity determinations for any 

ozone NAAQS for the Missouri portion of the St. Louis nonattainment area. Table 13 identifies 

the 2015 motor vehicle emissions budgets for the Missouri portion of the 2008 St. Louis 8-hour 

ozone nonattainment area for use in transportation conformity analyses.

4. Public Participation 

In accordance with Section 110(a)(2) of the CAA, the Missouri is required to hold a public 

hearing prior to adoption of this plan and the subsequent submittal to the EPA. The Department 

notified the public and other interested parties of the public hearing and comment period thirty 

(30) days prior to holding such hearing for this plan as follows: 

 Notice of availability of the early progress plan was posted on the Department of Natural 

Resources’ Air Pollution Control Program website on January 3, 2013: 

http://www.dnr.mo.gov/env/apcp/stateplanrevisions.htm

 The public hearing for the plan was held on February 5, 2013 beginning at 9:00 a.m. at 

the Elm Street Conference Center, in Bennett Springs Conference Room, 1730 East Elm 

Street, Jefferson City, MO 65101. 

 The public comment period for the plan opened when it was posted on the Department of 

Natural Resources’ Air Pollution Control Program website on January 3, 2013, and 

closed on February 13, 2013, seven days after the public hearing.

CONCLUSION 

This early progress plan demonstrates progress towards attainment of the 2008 ozone NAAQS in 

the Missouri portion of the St. Louis nonattainment area. As shown in Table 12, the overall CO, 

NOX and VOC emissions reductions from 2008 to 2015 are 27%, 31% and 12%, respectively. 

These emission reductions were based on control measures that are permanent and enforceable 

and will continue to improve the air quality in the area. Additionally, this early progress plan 

establishes motor vehicle emission budgets for VOC and NOX in the year 2015 that can be used 

in the Missouri portion of the St. Louis nonattainment area for regional transportation conformity 

determinations under the 2008 ozone NAAQS once the budgets are found adequate. 
Compliant with 643.055 RSMo, the Missouri Air Conservation Commission 

has determined that this action is needed to have a U.S. Environmental 

Protection Agency approved State Implementation Plan. 

The Revision to the State Implementation Plan - Early Progress Plan for the 

Missouri Portion of the St. Louis Nonattainment Area for the 2008 8-hour 

Ground-Level Ozone National Ambient Air Quality Standard is hereby 

adopted by the Missouri Air Conservation Commission this 28th of March, 

2013.

Missouri State Implementation Plan Revision - Early Progress Plan for the Missouri Portion of the St. 

Louis Nonattainment Area for the 2008 8-Hour Ground-Level Ozone National Ambient Air Quality 

Standard 

Pursuant to Section 176(c) of the Clean Air Act, this Early Progress Plan establishes transportation 

conformity motor vehicle emission budgets for Missouri's portion of the St. Louis nonattainment area 

under the 2008 8-hour Ozone National Ambient Air Quality Standard, or NAAQS. The St. Louis 

nonattainment area was deSignated as a marginal nonattainment area for the 2008 8-hour Ozone NAAQS 

on May 21, 2012. The new motor vehicle budgets are based on a demonstration that emissions are 

sf iily decreasing in the St. Louis area. Although the St. Louis nonattainment area has approved motor 

vemcle emissions budgets that have been used to demonstrate conformity under the 1997 8-hour Ozone 

NAAQS, new budgets are needed due to EPA's recent transition from an older on-road mobile source 

model, or Mobile 6, to the current on-road mobile model, or MOVES.

25 As stated in the executive summary, the
COMMENTS AND RESPONSES ON 

THE PROPOSED REVISION TO 

THE MISSOURI STATE IMPLEMENTATION PLAN — 

EARLY PROGRESS PLAN 

FOR THE MISSOURI PORTION OF THE ST. LOUIS NONATTAINMENT AREA FOR 

THE 2008 8-HOUR GROUND-LEVEL OZONE 

NATIONAL AMBIENT AIR QUALITY STANDARD 

AND 

RECOMMENDATION FOR ADOPTION

On February 5, 2013, the Missouri Air Conservation Commission held a public hearing in 

Jefferson City, Missouri concerning this proposed revision to the Missouri State Implementation 

Plan (SIP). This proposed revision to the SIP will add the following Early Progress Plan for the 

Missouri Portion of the St. Louis Nonattainment Area for the 2008 8-hour Ground-Level Ozone 

National Ambient Air Quality Standard (NAAQS). This early progress plan provides the basis 

for establishing transportation conformity motor vehicle emission budgets for Missouri’s portion 

of St. Louis nonattainment area under the 2008 ozone NAAQS. The following is a summary of 

comments received and the Missouri Department of Natural Resources' corresponding responses. 

Any changes to the proposed plan are identified in the responses to the comments. 

The document has not been printed in the briefing document due to its volume. The complete 

document, as amended, is available for review at the Missouri Department of Natural 

Resources’, Air Pollution Control Program, 1659 East Elm Street, Jefferson City, Missouri 

65101, (573) 751-4817. It is also available online at 

http://www.dnr.mo.gov/env/apcp/stateplanrevisions.htm 

The Missouri Department of Natural Resources’ Air Pollution Control Program recommends the 

commission adopt the plan action as amended. If the commission adopts this plan action, it will 

be the department’s intention to submit this plan to the U.S. Environmental Protection Agency 

for inclusion in the Missouri State Implementation Plan. 

SUMMARY OF COMMENTS: The department’s Air Pollution Control Program received two 

comments from the U.S. Environmental Protection Agency (EPA). 

COMMENT #1: The EPA commented that the narrative in Section 3 of the plan, the 

Transportation Conformity Section, indicated that the new motor vehicle emissions budgets 

established in the plan will replace the current motor vehicle emissions budgets established under 

the 1-hour ozone NAAQS. They noted that while the current budgets will no longer be used 

once the new budgets are found adequate by EPA, they will continue to exist, and therefore are 

not being replaced. EPA offered suggested language to better describe this situation. 

RESPONSE AND EXPLANATION OF CHANGE: The department’s Air Pollution Control 

Program appreciates the EPA’s comment that provides greater clarity and technical accuracy 

regarding the new motor vehicle emissions budgets established in the plan. As a result of this 
comment, the plan has been revised by incorporating language that is consistent with EPA’s 

suggestion into the Transportation Conformity Section of the document. 

COMMENT #2: The EPA suggested a language revision to Section 2 of the plan in order to 

provide additional clarity regarding the demonstration of progress towards attainment. 

RESPONSE AND EXPLANATION OF CHANGE: The department’s Air Pollution Control 

Program appreciates the EPA’s suggested language that improves clarity and accuracy of the 

plan. As a result of this comment, the plan has been revised by incorporating EPA’s suggested 

language into Section 2, the Demonstration of Progress towards Attainment Section of the 

document.

Table A-2 summarizes the area source emissions. This table includes refueling emissions for onroad motor vehicles estimated by MOVES2010a and account for the stage II controls that were 

in place in the St. Louis nonattainment area in 2008. In addition, due to the methods that are 

used to calculate the emissions for the aircraft, marine, and rail categories, these categories are 

included as area source emissions in the National Emissions Inventory (NEI), although they 

really should be classified as off-road mobile source emissions. Therefore, the emissions for 

aircraft, rail, and marine are not included in the total area source emissions listed in Table A-2. 

The source classification codes for the aircraft, rail and marine categories are listed in Table A-3, 

and the emissions from these categories are listed in Table A-24, to be included as off-road 

mobile source emissions.

Appendix A-2 On-Road Mobile Source Emissions Using MOVES 2010A 

EPA released the Mobile Vehicle Emission System (MOVES) in December of 2010, and 

MOVES is now the official model to use for mobile emissions modeling. 2008 mobile emissions 

were initially created using Mobile6.2 via NMIM for the St. Louis nonattainment area for the 

purpose of submitting state wide emissions data for EPA’s 2008 National Emissions Inventory 

(NEI). The NMIM NCD was updated with Missouri specific data. Local VMT data, vehicle 

registration distributions, and meteorology data from the updated NCD were converted to 

MOVES formatting using EPA provided conversion workbooks. 

The local VMT data was gathered from East-West Gateway at the county level. This data is 

listed in Table A-5 below. The road type distribution in the baseyearvmt table from the NCD 

was used to distribute the county level VMT to road type. EPA’s VMT converter workbook was 

then used to produce MOVES input tables. A vehicle registration distribution was originally 

created for NMIM using registration data from Missouri’s Department of Revenue. This 

registration distribution is listed below in Table A-6 below. The vehicle distribution was 

converted to MOVES age distribution table using EPA’s VMT converter workbook. The 

registration data was also used to create the MOVES vehicle population input tables. Vehicle 

counts were converted from Mobile 6.2 vehicle classes to MOVES source types using the source 

type fractions from the Source Type Pop Fractions table in EPA’s VMT converter workbook. 

The Air Program developed the I/M data input to accurately describe the Gateway Vehicle 

Inspection Program (GVIP), which is the I/M program in the St. Louis area. The protocol used 

to develop the I/M input in MOVES can be found in Appendix B. MOVES base data was used 

for all other inputs, after reviewing the data to ensure accuracy. The base fuel supply tables in 

MOVES were used for the runs, as they already took into account the reformulated gasoline used 

in the St. Louis nonattainment area. A separate input database was created for each county, 

using county specific data where possible. All of the MOVES input tables, other than templates 

where EPA default data was used, which were used to create the 2008 on-road mobile emissions 

inventory for the early progress plan can be found in this Appendix. 

The MOVES model runs were set up selecting all available gasoline and diesel fuel vehicle type 

combinations, all months, days, hours, and all road types. A separate run was set-up for each 

pollutant. The emissions were post-aggregated to the year level using MOVES. 

MOVES is a completely redesigned model, not just an updated version of the previous Mobile 

model. The way MOVES calculates emissions has changed to reflect EPA’s more current 

understanding of the emissions produced by vehicles and the various factors that affect the 

emissions. NOX emissions were found to be higher because of the larger portion extended idling 

of heavy duty vehicles contributes to the emissions total. PM2.5 emissions were also higher 

because of a better understanding of the effect of stop and go traffic, which has a significant 

impact on emissions in highly urban areas, such as the St. Louis nonattainment area. VOC 

emissions were roughly the same from both models, with minimal increases with the switch to 

MOVES. As a result of these changes to the model, MOVES produced higher emissions 

estimates for 2008 than were originally created with NMIM. 
 A-5 

Once MOVES input tables had been created, the MOVES model runs were set up selecting all 

available gasoline and diesel fuel vehicle type combinations, all months, days, hours, and all road 

types. A separate run was set-up for each pollutant and each county. All pollutant processes 

were selected in each run, but the VOC emissions from MOVES emission processes 18 and 19 

(refueling displacement emissions, and refueling evaporative emissions) were removed during 

the post model analysis as these are refueling emissions, which are classified as area source 

emissions, and are not included in the mobile source emissions inventory. The emissions were 

post aggregated to the month level and the emissions from the months of April through October 

were totaled and divided by 214, the number of days in those months, to give average ozone 

season day emissions. 

Table A-4 summarizes the 2008 ozone season day on-road emissions by county as calculated 

using MOVES 2010A for the Missouri counties located in the St. Louis ozone nonattainment 

area. Tables A-7 through A-22 provide all of the MOVES inputs that were used to create the 

2008 annual on-road mobile emissions inventory that were then used to generate the ozone 

season day emissions summarized in Table A-4, except for templates where EPA default data 

was used.

Appendix A-3 2008 Off-Road Mobile Source Emissions

The Air Program Staff followed the 2008 and 2022 modeling protocol submitted by EPA Region 

7 to the Department for the development of the 2008 off-road mobile emissions with some 

exceptions. The Staff used 3.5% oxygen weight instead of 0.35% and 100% ethanol blend 

market instead if 10%. The EPA’s modeling protocol can be found in Appendix A-4 of this 

document. The data generated by the Air Program Staff for the 2008 off-road mobile source 

emissions for the Missouri counties in the St. Louis ozone nonattainment area are summarized in 

A-23. 

As stated in Appendix A-1, EPA generated emissions data for aircraft, marine and rail sources 

using a method similar to the way emissions are generated for non-point sources. Therefore, 

2008 emissions data for aircraft, marine, and rail emissions, which are calculated similarly to 

nonpoint emissions, need to be added to the off-road mobile source category. The 2008 

emissions for rail, aircraft, and marine sources are summarized by county in Table A-24. The 

total off-road mobile source emissions by county are listed in Table A-25.

Nonroad modeling for inventory development 

For this modeling exercise, the EPA Region 7 utilized the NONROAD2008a model to calculate 

an ozone and PM2.5 nonroad inventory in five counties in the St. Louis nonattainment area for 

the 1997 PM2.5 annual and 1997 Ozone NAAQS. The NONROAD2008a model provides the 

emissions for all nonroad source categories except aircraft, commercial marine vessel, and 

railroad locomotive. 

In running the NONROAD model, the user must specify a modeling scenario by the inventory 

year, geographic area (nation, state, county), period (annual, seasonal, monthly, daily), and the 

equipment categories. For all other required variables, the NONROAD model provides default 

input values. For the following modeling exercises, fuel parameters (Reid Vapor Pressure 

(RVP), oxygen weight, sulfur content, ethanol volume and market percentage) and temperatures 

for each geographical area were provided by MDNR in lieu of the modeling default settings for 

more accurate results (see attachment). 

Ozone Precursor Emissions 

Ozone Methodology/Input Data 

Nonroad mobile source emissions for the years of 2008 and 2022 are calculated using the EPA 

approved model, NONROAD2008a, and included Franklin County, Jefferson County, St. 

Charles County, St. Louis County and St. Louis City in St. Louis, Missouri. 

For modeling ozone precursor pollutants, temperatures and fuel characteristics representative of 

each county during an ozone summer weekday, were entered into NONROAD2a and modeled to 

calculate an ozone season weekday emissions for nonroad sources. Minimum, maximum, and 

average temperatures for a typical summer season were provided by MDNR (see attachment). 

Modeling input parameters are as follows:

Direct PM2.5 / PM2.5 Precursor Emissions 

Methodology/Input Data 

Nonroad mobile source emissions for the years of 2008 and 2022 were calculated using the EPA 

approved model, NONROAD2008a, and included Franklin County, Jefferson County, St. 

Charles County, St. Louis County and St. Louis City in St. Louis, Missouri. 

For modeling PM2.5 and PM2.5 precursor pollutants, temperatures and fuel characteristics 

representative of each county for each of the four seasons (winter, spring, summer, and fall) were 

entered into the NONROAD2008a model as input parameters. The highest temperature and 

lowest temperature from each three month period (December-February, March-May, JuneAugust, and September-November) were averaged to create a seasonal average temperature. 

Those seasonal average temperatures, seasonal minimum and seasonal maximum temperatures 

were then utilized in the model, including the fuel parameters, to calculate the total emissions for 

each county and season. Summing the emissions of all four seasons for each county gave the 

total annual emissions. The temperatures and fuel characteristics representative of each county 

were provided by MDNR. Modeling input parameters are as follows:

QA/QC 

Quality control and quality assurance were conducted throughout this nonroad modeling process. 

Data collected from various data sources were verified and correctly entered or transcribed into 

the model. In some instances, input values, i.e., temperatures and fuel values were double 

and/or triple checked for accuracy to insure they corresponded to the data supplied by MDNR. 

In addition, a spot-checking of the modeling results, including rerunning the model for those 

results in question, was performed to insure reliability.

Appendix B-1 2015 Point Source Emissions 

All of the details associated with developing the 2008 point and area source emissions 

inventories are described in Appendix B-1 of this document. To forecast to the future year of 

2015, growth factors were obtained from the Economic Growth and Analysis System (EGAS) 

version 5.0, published in January 2006. The model forecasts economic activity to generate 

growth factors used to develop emission inventories. For this project, growth factors were 

obtained for 2015 year for the five counties of interest: Franklin (29071), Jefferson (29099), St. 

Charles (29183), St. Louis County (29189), and St. Louis City (29510). The default REMI 5.5 

(Regional Economic Model, Inc) configuration was used, and it includes growth based on 

economy, population, employment, consumption, and value-added for 53 major sectors of the 

economy. Factors were created for both point and area categories, and are broken out by SCC, 

county, and year. 

Point growth factors covered all point SCCs in use in Missouri for 2008. The county and SCCspecific growth factor was multiplied by the 2008 ozone season day emissions to get the 2015 

forecast point source inventory. The four electric utilities, Ameren’s Labadie, Meramec, Rush 

Island, and Sioux, in the St. Louis nonattainment area were grown as follows. The actual 

regulatory ozone season (May – September) NOX emissions from these Ameren units from 2008 

- 2011 were obtained from the Clean Air Market Division database and averaged to obtain a 

yearly regulatory ozone season average of NOX emissions over these four years. This yearly 

regulatory ozone season average of NOX emissions over these four years were then divided by 

153 (the number of days in the regulatory ozone season to obtain the projected average ozone 

season day emissions in 2015 for these four facilities. The average 2008 – 2011 regulatory 

ozone season NOX emissions and the calculated average ozone season day NOX emissions during 

the same time period for these four Ameren EGU facilities are listed in Table B-1. This four 

year average of regulatory ozone season NOX emissions was determined to be representative of 

the projected NOX emissions in 2015 because of CAIR. In 2015, their allowances from CAIR 

drop significantly, but they will likely have some banked allowances allowing them to hold their 

emissions pretty steady for the first few years after the 2015 CAIR allocations take effect. CO 

and VOC emissions from Ameren units were grown to 2015 using EGAS 5.0 growth factors. 

Table B-2 summarizes the total point source emissions projected for 2015 for the Missouri 

portion of the St. Louis ozone nonattainment area.

Appendix B-2 2015 Area Source Emissions 

Similarly to the 2015 point source emission projections, the 2015 area source emission 

projections were calculated using the 2008 area source emissions inventory and applying growth 

factors to project the emissions in 2015. The growth factor file included SCCs with non-numeric 

characters. These were identified and determined not to be placeholder SCCs that would be used 

to match to Missouri SCCs, and so they were removed. When the Missouri area SCCs were 

initially matched to the growth factors generated by EGAS 5.0, there were several categories that 

did not have a growth factor. Area SCCs added since 2006 would not be included in EGAS, so a 

similar growth factor had to be found. The area residential wood category has seen new SCCs 

added to account for EPA-certified stoves, hydronic heaters, and wax firelogs. EGAS provides a 

single growth factor for all other residential wood combustion, and so this single factor is used 

for the new SCCs. New SCCs for portable fuel containers are assigned the most similar growth 

factor for gasoline product storage. SCCs for bulk plant evaporation of gasoline are assigned the 

growth factor for bulk terminal evaporation of gasoline. 

Once all area SCCs had an assigned growth factor, the 2008 ozone season day emissions were 

multiplied by the growth factor specific to that county and SCC to get the 2015 forecast 

emissions. The county totals are summarized below in Table B-5. This table includes refueling 

emissions for on-road motor vehicles estimated by MOVES2010b. The stage II controls in 

MOVES2010b were “turned off” by setting the stage II control efficiencies in the countyyear 

input table to zero (0) for all counties in the Missouri portion of the St. Louis nonattainment area. 

This was done, because the Air Program is currently developing a SIP revision to remove stage 

II control requirements in the St. Louis area due to the widespread use of on-board vapor 

recovery systems. 

As stated in Appendix A, due to the methods that are used to calculate the emissions for the 

aircraft, marine and rail categories, these categories are included as area source emissions in the 

National Emissions Inventory, although they really should be classified as off-road mobile 

source emissions. Therefore, the emissions for aircraft, rail, and marine are not included in the 

total area source emissions listed in Table B-5. The source classification codes for the aircraft, 

rail, and marine categories are listed in Table B-6, and the emissions from these categories are 

listed in Table B-25, to be included as off-road mobile source emissions.

Appendix B-3 2015 On-Road Mobile Source Emissions Using MOVES 2010B

For this document, on-road mobile source emissions for 2008 were calculated using the EPA’s 

Motor Vehicle Emissions Simulator (MOVES) version 2010a and the on-road mobile source 

emissions for 2015 were calculated using MOVES version 2010b. The inputs to the model for 

2015 were developed using 2008 as the base year. Both vehicle miles traveled (VMT) data and 

source type population data for 2015, were grown annually by 1.5% from the 2008 data. 

The emissions for 2008 were calculated using 2008 VMT data provided by the East West 

Gateway Council of Governments. The 2008 VMT data was originally generated from the 

Missouri Department of Transportation for state-owned roads, and then East-West Gateway used 

their Traffic Demand Model to calculate the actual local VMT data for each of the five counties 

on the Missouri side of the St. Louis Ozone nonattainment area. 

The road type distribution input used in 2008 was developed from the National County Database 

(NCD) to distribute the county level VMT to road type. EPA’s VMT converter workbook was 

then used to produce MOVES input tables. The same road type distribution data that was used 

for 2008 was also used for 2015. A vehicle registration distribution for 2008 was originally 

created for the National Mobile Inventory Model (NMIM) using registration data from 

Missouri’s Department of Revenue. The vehicle distribution was converted to a MOVES age 

distribution table using EPA’s VMT converter workbook. The same age distribution table was 

used for 2015. The registration data was also used to create the MOVES vehicle population 

input tables for 2008. Vehicle counts were converted from Mobile 6.2 vehicle classes to 

MOVES source types using the source type fractions from the Source Type Pop Fractions table 

in EPA’s VMT converter workbook. The meteorology data used for 2008 was developed by 

EPA from National Weather Service data. The 2008 meteorology data was also used for the 

projected emissions in 2015. Inspection and Maintenance (I/M) input tables were developed to 

characterize the Gateway Vehicle Inspection Program (the I/M program in place in the St. Louis 

Ozone nonattainment area). Additional details regarding the development of the I/M input can 

be found in the I/M input table development protocol (Appendix B-3.1). 

MOVES base data was used for all other inputs to calculate the 2008 and 2015 mobile source 

emissions, after reviewing the data to ensure accuracy. The base fuel supply tables in MOVES 

were used for the runs, as they already took into account the reformulated gasoline used in the St. 

Louis nonattainment area. A separate input database was created for each county, using county 

specific data where possible. All of the data used to develop the county database manager inputs 

for the MOVES runs performed for 2008 and 2015, other than the data for county database 

manager inputs where EPA default data was used, can be found in Section 2 of this document. 

The MOVES model runs were set up selecting all available gasoline and diesel fuel vehicle type 

combinations, all months, days, hours, and all road types. A separate run was set-up for each 

pollutant and each county. All pollutant processes were selected in each run, but the VOC 

emissions from MOVES emission processes 18 and 19 (refueling displacement emissions, and 

refueling evaporative emissions) were removed during the post model analysis as these are 

refueling emissions, which are classified as area source emissions, and are not included in the 

mobile source emissions inventory. The emissions were post-aggregated to the month level 
 B-29 

using MOVES. Once the MOVES input tables had been created, MOVES was run and all 

months for 2008 and 2015 to create an annual emissions profile for each year. The VOC 

emissions for the months of April through October were totaled and divided by 214, the number 

of days in those months, to give average ozone season day VOC emissions for 2008 and 2015. 

Table B-8 shows 2015 on-road mobile source emissions in tons per ozone season day by county 

in the St. Louis nonattainment area.

When using MOVES 2010b to calculate the on-road mobile source emissions, default data was used in the county datab

Speed Distribution, Fuel Supply, Fuel Formulation, VMT Monthly Distribution, VMT Daily Distribution, and VMT Ho

for all five counties. Meteorology Data and Age Distribution Inputs are the same for 2015. For all county database manby the Air Program, the data used to develop these input tables is listed in Tables B-9 – B-23 below.

Appendix B-3.1 Developing the I/M Input Tables for MOVES for the St. Louis Ozone 

nonattainment area 

EPA has technical guidance on appropriate input assumptions and sources of data for the use of 

MOVES 2010 in State Implementation Plan 

(http://www.epa.gov/otaq/models/moves/420b10023.pdf). Section 3.10 of this guidance 

document explains the appropriate assumptions and methods to be used when developing the I/M 

input table for MOVES 2010. This guidance has been followed in the development of I/M input 

Tables 2 – 6 at the end of this document. This document outlines the approach used to develop 

each parameter of these I/M input tables in MOVES. The goal in developing these I/M input 

tables is to accurately reflect the actual I/M program being implemented in the St. Louis 

nonattainment area. 

Pollutant Process ID 

To begin development of the I/M input table, the default data for the I/M input table for St. Louis 

County was exported from the MOVES county database manager. The default data included 

four different I/M test types. However, the actual St. Louis area only had two different test types 

(On-board diagnostics) OBD tests for the exhaust and evaporative systems. In the default I/M 

input table, these were the only two types of tests that were “turned on” along with the 

appropriate pollutant process IDs that would be impacted by each test. Therefore, the pollutant 

process IDs that were included in the default table for the two OBD tests were the same pollutant 

process IDs used in the I/M input table for the St. Louis nonattainment area. The other two tests 

included in the default data along with their associated pollutant process IDs were still included 

in the I/M input table, but they were “turned off”. 

Source Type ID 

The St. Louis I/M program includes passenger cars and also trucks with a gross vehicle weight 

rating of 8,500 lbs. or less. Therefore, the three source type IDs included in the I/M input table 

for the St. Louis nonattainment area are passenger cars, passenger trucks, and light commercial 

trucks (IDs = 21, 31, and 32). 

Fuel Type ID 

The St. Louis I/M program is applicable to both gasoline and diesel vehicles; however, MOVES 

only calculates an I/M benefit for gasoline vehicles. Therefore, the fuel type ID for gasoline was 

the only uel type ID used in the I/M input table for the St. Louis nonattainment area. 

Inspection Frequency 

The St. Louis I/M program requires that emission be tested every two years, so the inspection 

frequency ID that represents biennial tests (ID = 2) was used in the I/M input table for the OBD 

tests applicable to the St. Louis nonattainment area. 
 B-46 

Test Standards 

The St. Louis I/M program is a centralized program with OBD tests for exhaust and evaporative 

systems on the vehicles. Therefore, the test standard IDs for exhaust OBD check and the 

evaporative system OBD check (IDs = 43 and 51) were used in the I/M input table for the St. 

Louis nonattainment area. 

I/M Program ID 

This is an arbitrary number developed by the MOVES user to define a unique test given for 

vehicles within a range of model years. Therefore, I/M program IDs were arbitrarily assigned to 

the various unique tests within the St. Louis I/M program. 

Beginning and Ending Model Years 

The St. Louis I/M program applies to gasoline vehicles with a model year of 1996 or later and it 

also applies to diesel vehicles with a model year of 1997 or later. Since the emissions inspection 

is required biennially, the ending model year would always be two years less than the emissions 

inventory year that is being developed. Therefore, for the tests for gasoline vehicles, the 

beginning model year is 1996 and the ending model year is two years earlier than the year for 

which MOVES is being run, and the for diesel vehicles the beginning model year is 1997 and 

the ending model year is two years earlier than the year for which MOVES is being run. 

Compliance Factor 

According to page 39 of the MOVES guidance document the compliance factor is calculated 

with the following equation: 

Compliance Factor = percent compliance rate x (100 – percent waiver rate) x regulatory 

class coverage adjustment. 

Therefore, in order to calculate the compliance factor for each source type included in the I/M 

program, the compliance rate, waiver rate, and regulatory class coverage adjustment needed to be 

determined. These three values were determined by the processes described below and then the 

compliance factors for each source type were calculated with the equation written above. 

Compliance Rate 

The compliance rate was calculated with the following equation: 

Compliance Rate = Number of vehicles that were tested over a two year period (2008 – 2009) / 

Population of vehicles that is theoretically subject to I/M during the same period. 

In order to determine the compliance rate, as it compares to the source type population by model 

year, the population of vehicles that is theoretically subject to I/M first needed to be determined. 

In May 2009, the Missouri Department of Revenue (DOR) Vehicle Registration database was 

queried and a VIN decoder was used to separate the vehicle counts into Mobile 6.2 vehicle 

classes by model year. In the St. Louis nonattainment area, the Mobile 6.2 vehicle classes that 
 B-47 

are subject to I/M include 1996 and newer light duty gasoline vehicles, light duty gasoline trucks 

Class 1, light duty gasoline trucks Class 2, light duty gasoline trucks Class 3, light duty gasoline 

trucks Class 4, as well as 1997 and newer light duty diesel vehicles, light duty diesel trucks Class 

1, light duty diesel trucks Class 2, light duty diesel trucks Class 3, and light duty diesel trucks 

Class 4. Table 1 below shows the total combined population of these 10 vehicle classes within 

the appropriate model years by county in the St. Louis nonattainment area according the May 

2009 DOR data.

Total 1,364,819 3,399

Total Count 1,368,218 

The Air Program also queried the I/M report generator to determine the total number of vehicles, 

which had their emissions tested at least once from January 1, 2008 through December 31, 2009. 

The query also included the total number of vehicles that received waivers during the same time 

period. Table 2 below, was generated with data from this query. 

Table 2. Initially Tested Vehicles that Received a Waiver in the St. Louis I/M Program 

from January 1, 2008 through December 31, 2009 

Using the data from Tables 1 and 2 above the compliance rate is calculated for the St. Louis I/M 

Program with the following equation: 
 B-48 

 Compliance Rate: (1,344,747 / 1,368,218) x 100% = 98.28% 

Waiver Rate 

The waiver rate is the percentage of vehicles that fail an initial I/M test and do not pass a retest, 

but do receive a certificate of compliance. The waiver rate was determined by dividing the 

number of vehicles that received waivers from January 1, 2008 through December 31, 2009 by 

the total number of vehicles that were tested at least once during the same time period. 

Therefore, the waiver rate was calculated for the St. Louis I/M Program with the following 

equation: 

 Waiver Rate: (4,761 / 1,344,747) X 100% = 0.35% 

Regulatory Class Coverage Adjustment 

The regulatory class coverage adjustment is an adjustment that accounts for the fraction of 

vehicles within a source type that are covered by the I/M program. Since the I/M program in St. 

Louis exempts vehicles with a gross vehicle weight rating above 8,500 lbs., the compliance 

factor needs to reflect the percentage of vehicles in the source types subject to I/M that are 

exempt because of their GVWR. Table A.3 in the Appendix of the MOVES Technical Guidance 

Document was used to develop adjustments to the compliance factor to account for this 

discrepancy. The adjustments are percentages of vehicle miles traveled by the various regulatory 

weight classes within a source type. The corresponding adjustment factors used for the three 

source categories are as follow: 

 Passenger cars: 100% 

 Passenger Trucks: 94% 

 Light Commercial Trucks: 88% 

Calculating the Compliance Factor 

Based on the calculations listed above the compliance factor for each source category impacted 

by the I/M program in St. Louis is listed below. 

Passenger cars: 98.28% x (100% - 0.35%) x 100% = 97.94%

Passenger Trucks: 98.28% x (100% - 0.35%) x 94% = 92.06%

Light Commercial Trucks: 98.28% x (100% - 0.35%) x 88% = 86.18%

Appendix B-4 2015 Off-Road Mobile Source Emissions

The Air Program Staff followed the 2008 and 2022 modeling protocol submitted by EPA Region 

7 to the Department for the development of the 2015 off-road mobile emissions with some 

exceptions. The Staff used 3.5% oxygen weight instead of 0.35% and 100% ethanol blend 

market instead if 10%. The modeling protocol can be found in Appendix B-4.1 of this 

document. The data generated by the Air Program Staff for the projected 2015 off-road mobile 

source emissions for the Missouri counties in the St. Louis ozone nonattainment area are 

summarized in B-24. 

As stated in Appendix B-2, due to the methods that are used to calculate the emissions for the 

aircraft, marine and rail categories, these categories are sometimes included as area source 

emissions, although they really should be classified as off-road mobile source emissions. 

Therefore, the emissions for aircraft, rail, and marine are not included in the total area source 

emissions listed in Table B-5. The projected 2015 emissions for aircraft, rail, and marine sources 

are summarized by county in Table B-25. The total projected 2015 off-road mobile source 

emissions by county are listed in Table B-26.

Nonroad modeling for inventory development 

For this modeling exercise, the EPA Region 7 utilized the NONROAD2008a model to calculate 

an ozone and PM2.5 nonroad inventory in five counties in the St. Louis nonattainment area for 

the 1997 PM2.5 annual and 1997 Ozone NAAQS. The NONROAD2008a model provides the 

emissions for all nonroad source categories except aircraft, commercial marine vessel, and 

railroad locomotive. 

In running the NONROAD model, the user must specify a modeling scenario by the inventory 

year, geographic area (nation, state, county), period (annual, seasonal, monthly, daily), and the 

equipment categories. For all other required variables, the NONROAD model provides default 

input values. For the following modeling exercises, fuel parameters (Reid Vapor Pressure 

(RVP), oxygen weight, sulfur content, ethanol volume and market percentage) and temperatures 

for each geographical area were provided by MDNR in lieu of the modeling default settings for 

more accurate results (see attachment). 

Ozone Precursor Emissions 

Ozone Methodology/Input Data 

Nonroad mobile source emissions for the years of 2008 and 2022 are calculated using the EPA 

approved model, NONROAD2008a, and included Franklin County, Jefferson County, St. 

Charles County, St. Louis County and St. Louis City in St. Louis, Missouri. 

For modeling ozone precursor pollutants, temperatures and fuel characteristics representative of 

each county during an ozone summer weekday, were entered into NONROAD2a and modeled to 

calculate an ozone season weekday emissions for nonroad sources. Minimum, maximum, and 

average temperatures for a typical summer season were provided by MDNR (see attachment).

Methodology/Input Data 

Nonroad mobile source emissions for the years of 2008 and 2022 were calculated using the EPA 

approved model, NONROAD2008a, and included Franklin County, Jefferson County, St. 

Charles County, St. Louis County and St. Louis City in St. Louis, Missouri. 

For modeling PM2.5 and PM2.5 precursor pollutants, temperatures and fuel characteristics 

representative of each county for each of the four seasons (winter, spring, summer, and fall) were 

entered into the NONROAD2008a model as input parameters. The highest temperature and 

lowest temperature from each three month period (December-February, March-May, JuneAugust, and September-November) were averaged to create a seasonal average temperature. 

Those seasonal average temperatures, seasonal minimum and seasonal maximum temperatures 

were then utilized in the model, including the fuel parameters, to calculate the total emissions for 

each county and season. Summing the emissions of all four seasons for each county gave the 

total annual emissions. The temperatures and fuel characteristics representative of each county 

were provided by MDNR. Modeling input parameters are as follows:

QA/QC 

Quality control and quality assurance were conducted throughout this nonroad modeling process. 

Data collected from various data sources were verified and correctly entered or transcribed into 

the model. In some instances, input values, i.e., temperatures and fuel values were double 

and/or triple checked for accuracy to insure they corresponded to the data supplied by MDNR. 

In addition, a spot-checking of the modeling results, including rerunning the model for those 

results in question, was performed to insure reliability.

1.0 Introduction 

1.1 Purpose 

This document meets the nonattainment plan provisions under the Clean Air Act Section 

172 (c) (3): 

“Such plan provisions shall include a comprehensive, accurate, current inventory

of actual emissions from all sources of the relevant pollutant or pollutants in such

area, including such periodic revisions as the Administrator may determine

necessary to assure that the requirements of this part are met.”

Missouri’s redesignation request and maintenance plan for the 1997 Ozone National 

Ambient Air Quality Standard (NAAQS) require a base year emissions inventory for 

2008. The inventory is comprehensive in it’s inclusion of multiple source categories 

(point, nonpoint or area, and mobile sources), it is accurate based on the quality assurance 

steps outlined in Section 4, contains current 2008 actual emissions for the pollutants of 

concern for ozone, and can be updated through the triennial National Emissions 

Inventory (NEI). Emissions are documented for the St. Louis Nonattainment (STLNA) 

counties. Though the nonattainment area is bi-state, the inventory documentation that 

follows covers the five-county Missouri portion of the nonattainment area. 

1.2 Inventory Coverage 

1.2.1 Geography 

The inventory covers the St. Louis Nonattainment counties of Jefferson, Franklin, St. 

Charles, and St. Louis Counties and the City of St. Louis. Several summaries of 

statewide Missouri totals are also included for reference. There are no inventory 

components provided by local or tribal agencies. 

1.2.2 Emission Year 

Emission year 2008 is the base year, including ozone season day emissions for the 

Missouri St. Louis Ozone Nonattainment Area. 

1.2.3 Pollutants 

The pollutants covered in the inventory are ozone precursor emissions of NOx, VOC, and 

CO. 
Page 7 

1.3 Contents of Report 

This report documents the 2008 inventory in detail, from its creation, quality assurance, 

and final summaries. It also details the qualifications and limitations of the inventory. 

The document is arranged by purpose, emission summaries, documentation, quality 

assurance, and detailed appendices with lengthy emissions data tables and EPA provided 

category documentation. 

1.4 Automated Systems Used 

The 2008 emission inventory is maintained across multiple computing systems. Point 

source inventories are compiled from facility-supplied information in the Missouri 

Emissions Inventory System (MoEIS) database. Point sources are allowed to submit 

their inventory data via the MoEIS web interface or on hardcopy paper forms which are 

data entered to the electronic system. Nonpoint emissions are calculated using 

Microsoft® Excel spreadsheet and Access database tools. Mobile emissions are 

estimated using EPA’s Motor Vehicle Emissions Simulator (MOVES), the MOBILE6 

model, and the National Mobile Inventory Model (NMIM) which incorporates the 

NONROAD2008 model. 

1.5 Inventory Exclusions 

This 2008 inventory does not include biogenic or geogenic emissions. The inventory 

does not include the nonpoint categories for wildfire, prescribed, or agricultural burning, 

agricultural tilling, plus others described in section 3.2.2. This inventory does not include 

hazardous air pollutant (HAP) inventories as they are not relevant pollutants. Point 

emissions data is summarized at the facility level in this document, though facility 

operational data and emission process data is collected and submitted to the NEI.

3.0 Inventory Documentation 

3.1 Point Source Emissions 

3.1.1 Procedures and Methodologies 

The point source inventory is based on information collected on Emissions Inventory 

Questionnaires (EIQs). Facilities with a construction or operating permit from the Air 

Pollution Control Program are required to submit an EIQ on an annual basis per 10 CSR 

10-6.110. The EIQ details the amount of air pollution emitted and other operational data 

for the previous calendar year. 

2008 point sources include those with Part 70 and Intermediate operating permits. The 

EIQ solicitation was mailed to facilities in January 2009. The due date for 2008 reporting 

was June 1, 2009, and all point source reports were received and included in this 

document summary. 

3.1.2 Emission Inventory Questionnaire (EIQ) 

All point source emissions data for the State of Missouri is contained in a database called 

the Missouri Emissions Inventory System (MoEIS). Emission reports may be submitted 

either directly via the MoEIS web interface, a user-friendly, online portal linked directly 

to the MoEIS database, or they may be submitted on the hardcopy EIQ forms. Hardcopy 

EIQ submittals are then data entered into the MoEIS database by EI unit staff members. 

As a result, the MoEIS database is updated yearly with the most current emissions data 

for the State of Missouri. 

Hardcopy EIQ forms are described in Table 3, and the forms appear in Appendix C-8. 

All hardcopy forms have an electronic counterpart in the MoEIS web interface system. 

In general, forms beginning with number one (1) provide general information about a 

facility, forms beginning with a two (2) provide the detailed annual emission calculations, 

including activity or throughput, emission factors, emissions, and operational 

characteristics. More information on EIQ forms and instructions and MoEIS is available 

at http://www.dnr.mo.gov/env/apcp/moeis/emissionsreporting.htm

Point source EIQ data received via hard copy forms is data entered to the MoEIS 

emissions database by emission inventory staff. During this step, process-level emissions 

and operational information are checked for consistency between the hardcopy forms and 

database calculations, and inconsistencies are flagged for review. Problems include, but 

are not limited to: 

 Incorrect Source Classification Codes (SCCs) 
Page 14 

Emission unit numbering changes 

Calculation errors 

Missing or incomplete records 

Transposition errors 

If no errors are found during data entry, and the emissions reported on the hardcopy full 

EIQ match what is calculated by the MoEIS database, then the emission report is 

considered complete and data entered. 

EIQs with inconsistencies are moved from emission inventory data entry staff to a 

member of the technical review team. The technical review team will address the 

problems encountered during data entry by identifying the specific issue(s) and possible 

causes and contacting the facility to resolve those issues. Other issues may also be 

addressed during the review, including the appropriate use of emission estimation 

methods, documentation of source data, and consistency with permit emission 

calculations. Supplemental EIQ information may be collected by staff via telephone or 

email contact with the facility in question. Information collected in this manner will be 

recorded on the EIQ for reference, tracking and QA auditing. If the facility is requested to 

submit follow up verification or additional information in writing, a statement pertaining 

to this request will also be recorded on the EIQ. The information recorded will include 

the date of the call or contact, staff person’s name, contact person’s name, and written 

documentation of the call. 

After the submission deadline of June 1 has passed, a list of unsubmitted EIQs is 

generated and sent to the compliance and enforcement section of the Air Pollution 

Control Program. With all emissions data contained in the MoEIS database, further 

quality assurance steps are completed as described in Section 4. 

3.1.3 List of Facilities and Emissions 

There are 139 facilities in the point source inventory for the Missouri counties of the St. 

Louis nonattainment area. Their primary economic activity described by their North 

American Industry Classification System (NAICS) code is listed in Table 4 by county. 

Of these 139 facilities, only 131 report emissions of ozone precursors, and these facilities 

are listed in Table 5. The emission listing includes both annual and ozone season day 

emissions of CO, NOx and VOC. Ozone season day emissions are calculated on the EIQ 

form 2.0Z, Ozone Season Information. The facility reported maximum daily throughput 

during the ozone season is multiplied by the pollutant emission factor and reduced by 

control device to reach the ozone season daily emissions.

3.2 Nonpoint Source Emissions 

3.2.1 Procedures and Methodologies 

The nonpoint (also known as area) source categories with published methods of estimation are 

too numerous to calculate county-level inventories given current resources. The EPA, in 

conjunction with the Eastern Region Technical Advisory Committee (ERTAC), will complete 

inventory documentation and calculation for most nonpoint source categories using national 

defaults. Several categories are then improved with state-level information or with point-source 

subtraction. 

Missouri prepared inventories for 18 categories that required point source subtraction or statespecific data. These categories are listed in the Missouri Category Summary section below. 

Documentation of the calculation methodology and data sources is included in Table 11. 

Categories that did not require point source subtraction that were calculated by EPA are listed in 

the EPA Category Summary section. 

Nonpoint category ozone season day emissions were calculated from EMCH temporal allocation 

profiles that are SCC-specific. Ozone season day emissions are typical of a Tuesday in July. 

See Appendix C-7 for the temporal allocation method and calculation tables. 

3.2.2 List of Source Categories and Emissions 

Table 9 lists nonpoint annual emissions in tons per year by county and SCC. Table 10 

summarizes nonpoint ozone season day emission totals by county in tons per day, and the 

detailed ozone season day emission records by county and SCC are listed in Appendix C-7.

3.2.3 Source Category Documentation 

The following documentation covers nonpoint categories that were prepared with guidance from 

EPA and CENRAP. The documentation files include methodologies to be applied nationally, 

and include Missouri-specific updates and information. 

3.2.3.1 Fugitive Dust from Paved Roads 

a. Source Category Description 

Fugitive dust emissions from paved road traffic were estimated for PM10-PRI, PM10-FIL, PM25-

PRI, and PM25-FIL. Since there are no PM-CON emissions for this category, PM10-PRI 

emissions are equal to PM10-FIL emissions and PM25-PRI emissions are equal to PM25-FIL. 

For this source category, the following SCC was assigned:

The table below provides a national summary of the estimated 2008 annual vehicle miles 

traveled (VMT) activity and emissions by pollutant. VMT from 2007 were used to estimate the 

VMT from 2008 which were unavailable.

Uncontrolled paved road emissions were calculated at the State level by roadway class and 

month. This was done by multiplying the State/roadway class VMT by the appropriate monthly 

temporal allocation factor and by the paved road emission factor. After the paved road dust 

emissions were calculated at the State/road class/monthly level of detail, the uncontrolled 

emissions were then allocated to the county level using total VMT as a surrogate. Next, control 
Page 77 

factors were applied to the paved road emissions in PM10 nonattainment area counties. Emissions 

and VMT by roadway class were then totaled to the county level for reporting in the NEI. The 

following provides further details on the emission factor equation, temporal and spatial 

allocation procedures, and controls. 

b. Emission Factor Equation 

Reentrained road dust emissions for paved roads were estimated using paved road VMT and the 

emission factor equation from AP-42:1

E = [ k * (sL/2)0.65 * (W/3)1.5 - C ] * [1 - P/(4*N)] 

where: E = paved road dust emission factor (gram [g]/VMT) 

k = particle size multiplier (7.3 g/VMT for PM10-PRI/-FIL and 1.1 g/VMT for 

PM25-PRI/-FIL) 

sL = road surface silt loading (g/square meter [m2]) 

W = average weight (tons) of all vehicles traveling the road 

C = emission factor for 1980's vehicle fleet exhaust, brake wear, and tire wear 

(0.2119 g/VMT for PM10-PRI/-FIL and 0.1617 g/VMT for PM 2.5-PRI/-FIL) 

N = number of days in the month 

P = number of days in the month with at least 0.01 inches of precipitation 

The uncontrolled PM10-PRI/-FIL and PM25-PRI/-FIL emission factors are provided in attached 

file “Paved Roads PM Emission Factors.xls” by State, roadway class, and month. 

Paved road silt loadings were assigned to each of the twelve functional roadway classes (six urban 

and six rural) based on the average annual traffic volume of each functional system by State.2

The resulting paved road silt loadings calculated from the average annual traffic volume data are 

shown in Table 2. 

The AP-42 equation listed above includes a correction factor to adjust for the number of days 

with measurable precipitation in each month. The factor of “4" in the precipitation adjustment 

accounts for the fact that paved roads dry more quickly than unpaved roads and that precipitation 

may not occur over the entire 24-hour day period. The number of days with at least 0.01 inches of 

precipitation in each month by State was obtained from the National Climatic Data Center.3 Data 

were collected from a meteorological station selected to be representative of urban areas within 

each State. There are cases where the emission factor calculated using the equation above ends 

up negative due to the subtraction of the C term that accounts for vehicle exhaust, brake wear, and 

tire wear. In these cases, the emission factor was reset to 0, under the assumption that the 

emissions have been accounted for in the onroad emission inventory. 

c. Activity 

Total annual VMT estimates by State and roadway class were obtained from the Federal Highway 

Administration’s (FHWA) annual Highway Statistics report.2 Paved road VMT was calculated by 

subtracting the State/roadway class unpaved road VMT from total State/roadway class VMT.

d. Allocation

The paved road VMT estimates by State/roadway class were first temporally allocated by season 

using the National Acid Precipitation Assessment Program (NAPAP) Inventory seasonal temporal 

allocations factors for VMT.4 These factors are included in the attachment “Unpaved Road 

county allocation fractions.xls.” The seasonal VMT values were then multiplied by the ratio of 

the number of days in a month to the number of days in a season to adjust to monthly VMT. The 

emission factors were then applied to estimate emissions by month. 

The paved road activity and emissions were spatially allocated to counties according to the 

fraction of total VMT in each county for the specific roadway class as shown by the following 

equation: 
Page 78 

EMISx,y = EMISST,y * VMTx,y / VMTST,y

where: EMISx,y = paved road emissions (tons) for county x and roadway class y 

EMISST,y = paved road emissions (tons) for the entire State for 

roadway class y VMTx,y = total VMT (million miles) in county x and 

roadway class y VMTST,y = total VMT (million miles) in entire State 

for roadway class y 

The county-level VMT by roadway class developed to calculate onroad mobile source emissions 

was used in this equation.5 Note that because of differences in the methodologies for calculating 

total and unpaved road VMT, there are rural counties where unpaved road VMT was higher than 

total VMT. For these counties, unpaved VMT was reduced to total VMT and paved road VMT 

was assigned a value of zero. 

e. Controls

Paved road dust controls were applied by county to urban and rural roads in serious PM10

nonattainment areas and to urban roads in moderate PM10 nonattainment areas. The assumed 

control measure is vacuum sweeping of paved roads twice per month. A control efficiency of 79 

percent was assumed for this control measure.6 The assumed rule penetration varies by roadway 

class and PM10 nonattainment area classification (serious or moderate).6 The rule penetration 

rates are shown in Table 3. Rule effectiveness was assumed to be 100% for all counties where 

this control was applied. 

Note that the controls were applied at the county/roadway class level, and the controls differ by 

roadway class. In the NIF 3.0 emissions table, the emissions for all roadway classes were 

summed to the county level. Therefore, the emissions at the county level can represent several 

different control, rule effectiveness, and rule penetration levels. As a result, the control 

efficiency, rule effectiveness, and rule penetration values were reported in the control equipment 

table as a composite, overall control level for each county; the rule effectiveness and rule 

penetration values were not reported separately in the emission table.

3.2.3.2 Fugitive Dust from Unpaved Roads 

a. Source Category Description 

Fugitive dust emissions from unpaved road traffic were estimated for PM10-PRI, PM10-FIL, 

PM25-PRI, and PM25-FIL. Since there are no PM-CON emissions for this category, PM10-PRI 

emissions are equal to PM10-FIL emissions and PM25-PRI emissions are equal to PM25-FIL. 

For this source category, the following SCC was assigned:

Uncontrolled unpaved road emissions were calculated at the State level by roadway class and 

month. This was done by multiplying the State/roadway class unpaved roadway VMT by the 

appropriate monthly temporal allocation factor and by the monthly unpaved road emission 

factor. After the unpaved road dust emissions were calculated at the State/roadway 

class/monthly level of detail, the uncontrolled emissions were then allocated to the county level 

using 1990 rural population data as a surrogate. Next, control factors were applied to the unpaved 

road emissions in PM10 nonattainment area counties. Emissions and VMT by roadway class were 

then totaled to the county level for reporting in the NEI. The following provides further details 

on the emission factor equation, temporal and spatial allocation procedures, and controls. 

b. Emission Factor Equation 

Reentrained road dust emissions for unpaved roads were estimated using unpaved road VMT and the emission factor equation from AP-42:1

E =[ k * (s/12)1 * (SPD/30)0.5] / 

(M/0.5)0.2 - C where k, and C are empirical constants given in Table 

2, with 

k = particle size multiplier (lb/VMT) 

E = size specific emission factor (lb/VMT) 
Page 83 

s = surface material silt content (%) 

SPD = mean vehicle speed (mph) 

M = surface material moisture content (%) 

C = emission factor for 1980's vehicle fleet exhaust, brake wear, and tire wear (lb/VMT) 

The uncontrolled emission factors are provided in the attachment “Unpaved Roads PM Emission 

Factors.xls” by State, roadway class, and month. 

Average State-level unpaved road silt content values, developed as part of the 1985 NAPAP 

Inventory, were obtained from the Illinois State Water Survey.2 Silt contents of over 200 

unpaved roads from over 30 States were obtained. Average silt contents of unpaved roads were 

calculated for each sate that had three or more samples for that State. For States that did not 

have three or more samples, the average for all samples from all States was used as a default 

value. The silt content values by State, and identifies if the values were based on a sample 

average or default value.

were determined based on the average speeds modeled for onroad emission calculations and 

weighted to determine a single average speed for each of the roadway classes. The value of 0.5 

percent for M was chosen as the national default as sufficient resources were not available at the 

time the emissions were calculated to determine more locally-specific values for this variable.

Correction factors were applied to the emission factors to account for the number of days with a 

sufficient amount of precipitation to prevent road dust resuspension. Monthly corrected emission 

factors by State and roadway classification were calculated using the following equation: 

Ecorr = E * [(D-p)/D] 

where: Ecorr = unpaved road dust emission factor corrected for precipitation effects 

E = uncorrected emission factor 

D = number of days in the month 

p = number of days in the month with at least 0.01 inches of 

precipitation 

The number of days with at least 0.01 inches of precipitation in each month was obtained from the 

National Climatic Data Center.3 Data were collected from a meteorological station selected to be 

representative of rural areas within the State. 

c. Activity 

Unpaved roadway mileage estimates were obtained from the FHWA’s annual Highway Statistics 

report.4 Unpaved mileage data for 2007 were used, as data for 2008 were not yet available. 

Separate calculations of VMT were performed for county- and noncounty- (State or federally) 

maintained roadways. State-level, county-maintained roadway mileage was organized by 

surface type (rural and urban) and the average daily traffic volume (ADTV) groups shown in 

Table 4. From these data, State-level unpaved roadway mileage estimates were made. The 

following equation was then used to calculate State-level unpaved road VMT estimates: 

VMTUP = ADTV * FSRM * 366 days/year 

where: VMTUP = VMT on unpaved roads (miles/year) 

ADTV = average daily traffic volume 

(vehicles/day/mile) FSRM = functional system 

roadway mileage (miles) 

State and federally maintained roadway mileage was categorized by arterial classification, not 

roadway traffic volume; therefore, the VMT was calculated differently than for countymaintained roadways. The ADTV was assumed to not vary by roadway maintenance 

responsibility, so the ADTV calculated from county-maintained VMT and mileage (ADTV = 

VMT / Mileage) was used with noncounty-maintained roadway mileage to calculate VMT in the 

above equation.

d. Allocation

The unpaved road VMT estimates by State/roadway class were first temporally allocated by 

season using the NAPAP Inventory seasonal temporal allocations factors for VMT.5 These 

factors are provided in the attachment “Paved and Unpaved Road VMT temp factors.xls”. The 

seasonal VMT values were then multiplied by the ratio of the number of days in a month to the 

number of days in a season to adjust to monthly VMT. The emission factors were then applied to 

estimate emissions by month. 

The State/roadway class unpaved road emissions were then spatially allocated to each county 

using estimates of the ratio of 1990 county rural population to the State rural population from the 

U.S. Census Bureau6 as shown by the following equation: 

EMISx,y =(CLx / SL) * EMIS,y

where: EMISx,y = unpaved road emissions (tons) for county x and roadway class y 

CLx = rural population in county x SL = rural population 

in the State EMIS,y = unpaved road emissions in entire 

State for roadway class y 

The county-level allocation factors are provided in the attachment “Unpaved Road county 

allocation fractions.xls.” 

e. Controls

The controls assumed for unpaved roads varied by PM10 nonattainment area classification and by 

urban and rural areas. On urban unpaved roads in moderate PM10 nonattainment areas, paving of 

the unpaved road was assumed, and a control efficiency of 96 percent and a rule penetration of 

50 percent were applied. Chemical stabilization, with a control efficiency or 75 percent and a 

rule penetration of 50 percent, was assumed for rural areas in serious PM10 nonattainment areas. 

A combination of paving and chemical stabilization, with a control efficiency of 90 percent and a 

rule penetration of 75 percent, was assumed for urban unpaved roads in serious PM10

nonattainment areas.7

Note that the controls were applied at the county/roadway class level, and the controls differ by 

roadway class. In the NIF 3.0 emissions table, the emissions for all roadway classes were 

summed to the county level. Therefore, the emissions at the county level can represent several 

different control, rule effectiveness, and rule penetration levels. As a result, the control 

efficiency, rule effectiveness, and rule penetration values were reported in the control equipment 

table as a composite, overall control level for each county; the rule effectiveness and rule 

penetration values were not reported separately in the emissions table.

3.2.3.3 Fossil Fuel Combustion – Residential – Coal Combustion 

a. Source Category Description 

Residential Coal Combustion is coal that is burned to heat residential housing. 

The general approach to calculating emissions for these two SCCs is to take State Coal 

Consumption from the EIA and allocate it to the county level using methods described below. 

County-level coal consumption is multiplied by the emission factors to calculate emissions. 

For this source category, the following SCCs were assigned: 

SCC Descriptor 1 Descriptor 3 Descriptor 6 Descriptor 8 

2104001000 Stationary Source 

Fuel Combustion 

Residential Anthracite Coal All Boiler Types 

2104002000 Stationary Source 

Fuel Combustion 

Residential Bituminous/ 

Subbituminous Coal 

All Boiler Types 

b. Activity Data 

The mass of coal consumed by residential combustion in the U.S. was used to estimate 

emissions. Coal consumption by energy use sector is presented in State Energy Data 2006 

Consumption tables published by the Energy Information Administration (EIA).1 Year 2006 

consumption data were used as a surrogate for 2008 emissions because year 2006 data were the 

latest data available when this inventory was prepared. 

EIA data do not distinguish between anthracite and bituminous coal consumption estimates. The 

EIA table “Domestic Distribution of U.S. Coal by Destination State, Consumer, Origin and 

Method of Transportation,” provides state-level residential coal distribution data for 2006 that 

was used to estimate anthracite and bituminous coal consumption. The amount of anthracite 

distributed to each state and the total coal delivered to each state were used to estimate the 

proportion of anthracite and bituminous coal consumption.2

 The 2006 ratio of anthracite (and 

bituminous) coal consumption to total coal consumption was used to distribute the EIA’s total 

residential sector coal consumption data by coal type. Table 1 presents the 2006 anthracite and 

bituminous coal ratios for each state. 

State-level coal consumption was allocated to each county using the US Census Bureau’s 2000 

Census Detailed Housing Information.3

 These data include the number of housing units using a 

specific type of fuel for residential heating. State coal consumption was allocated to each county 

using the ratio of the number of houses burning coal in each county to the total number of houses 

burning coal in the State. 

c. Control Factors 

No controls were assumed for this category 

d. Emission Factors 
Page 88 

In some cases (see Table 2), SO2 and PM emission factors required information on the sulfur 

and/or ash content of the coal burned. State-specific sulfur and ash contents of anthracite and 

bituminous coal were obtained from data compiled in preparing the 1999 residential coal 

combustion emissions estimates.4

 This study mostly relied on data obtained from USGS 

COALQUAL database. States not included in the database but that reported coal usage were 

assigned values based on their proximity to coal seams or using an average value for 

Pennsylvania (see report for details of the analysis). Table 3 presents the bituminous coal sulfur 

content values used for each state. For anthracite coal, an ash content value of 13.38% and a 

sulfur content of 0.89% were applied to all states except New Mexico (ash content 16.61%, 

sulfur content 0.77%), Washington (ash content 12%, sulfur content 0.9%), and Virginia (ash 

content 13.38%, sulfur content 0.43%). 

The remaining criteria pollutant and HAP emissions were calculated by multiplying the total coal 

consumed in each county per year by an emission factor. All emission factors except ammonia 

are from AP-42.5

 The ammonia emission factor is from EPA’s Estimating Ammonia Emissions 

from Anthropogenic Sources, Draft Final Report.

 Table 4 presents a summary of the emission 

factors for residential anthracite coal combustion (SCC 2104001000). Table 5 presents a 

summary of the emission factors for residential bituminous coal combustion (SCC 2104002000). 

e. Sample Calculations 

Annual emissions are calculated for each county using emission factors and activity as: 

 Ex,p = FCx × (1 - CEx,p) × EFx,p

where: 

 Ex,p = annual emissions for fuel type x and pollutant p (ton/year), 

 FCx = annual fuel consumption for fuel type x, 

 CEx,p = control efficiency for fuel type x and pollutant p, and 

EFx,p = emission factor for fuel type x and pollutant p. 

County level fuel consumption is calculated using: 

FCx = AState x RatioAnth, Bit x RatioCounty houses

where: 

 AState = total tons of coal reported by the EIA, 

 RatioAnth, Bit = ratio reported in Table 1, and 

 RatioCounty houses = county allocation ratio based on number of houses burning coal. 

Example: 

Using Allegheny County, PA as an example: 

The State of Pennsylvania had a reported use of 49,935 tons of coal in the residential sector in 

2006. 
Page 89 

Statewide Anthracite coal use is calculated using the ratio of Anthracite to Bituminous in Table 1 

for PA: 80.64%. Allegheny County, PA had 183 houses out of the state total of 67,986 that use 

coal as the primary heating fuel. This equates to a share of 0.27% of the coal used for residential 

heating in the state. 

The emission factor for PM2.5-PRI (See Table 4) is 0.6 × state-specific % ash content + 0.08 

lbs/ton× state-specific % ash content. The ash content is 13.38%, (See Table 2) so the emission 

factor is 9.09 lbs/ton. 

FCAllegheny, anth = 49,935 × 0.8064 × 0.0027 = 109 tons anthracite coal 

EmisAllegheny, anth, PM2.5-PRI = 109 tons Coal × 9.09 lbs PM2.5-PRI per ton coal 

 = 990 lbs PM2.5-PRI

3.2.3.4 Fossil Fuel Combustion – Residential – Distillate Oil

a. Source Category Description

Residential Distillate Oil Combustion is oil that is burned in residential housing

The general approach to calculating emissions for this SCC is to take State Distillate Oil 

Consumption from the EIA and allocate it out to the county level using methods described 

below. County-level oil consumption is multiplied by the emission factors to calculate 

emissions. 

For this source category, the following SCCs were assigned: 

SCC Descriptor 1 Descriptor 3 Descriptor 6 Descriptor 8 

2104004000 Stationary Source 

Fuel Combustion 

Residential Distillate Oil Total Boilers and 

IC Engines 

b. Activity Data 

The state-level volume of distillate oil consumed by residential combustion in the U.S. was used 

to estimate emissions. Distillate oil consumption by energy use sector is presented in State 

Energy Data 2006 Consumption tables published by the Energy Information Administration 

(EIA).1 Year 2006 consumption data were used as a surrogate for 2008 emissions because year 

2006 data were the latest data available when this inventory was prepared. 

State-level distillate oil consumption was allocated to each county using the US Census Bureau’s 

2000 Census Detailed Housing Information.2 These data include the number of housing units 

using a specific type of fuel for residential heating. State distillate oil consumption was allocated 

to each county using the ratio of the number of houses burning distillate oil in each county to the 

total number of houses burning distillate oil in the State. 

c. Control Factors 

No control measures are assumed for this category. 

d. Emission Factors 
Page 97 

Criteria pollutant emission factors for distillate oil are from AP-42. 3 For all counties in the 

United States, the distillate oil consumed by commercial/institutional combustion is assumed to 

be No. 2 fuel oil with a heating value of 140,000 Btu per gallon and a sulfur content of 0.30%.4

 

Dioxin/furan and HAP emission factors are from “Documentation of Emissions Estimation 

methods for Year 2000 and 2001 Mobile Source and Nonpoint Source Dioxin Inventories”5

 and 

“Documentation for the 1999 Base Year Nonpoint Area Source National Emission Inventory for 

Hazardous Air Pollutants,”6

 respectively. Sulfur content was 0.30% and was obtained from data 

compiled in preparing the 1999 residential coal combustion emissions estimates.7

 The ammonia 

emission factor is from EPA’s Estimating Ammonia Emissions from Anthropogenic Sources, 

Draft Report.

8

e. Sample Calculations 

Emissions are calculated for each county using emission factors and activity as: 

 Ex,p = FCx × EFx,p

where: 

 Ex,p = annual emissions for fuel type x and pollutant p 

 FCx = annual fuel consumption for fuel type x 

 EFx,p = emission factor for fuel type x and pollutant p 

And FCx = AState x (Hcounty / HState) 

where : 

 AState = State activity data from EIA 

 HCounty = number of houses in the county using distillate oil as the primary heating fuel 

 HState = number of houses in the state using distillate oil as the primary heating fuel 

Example: 

Using Allegheny County, PA as an example: 

The State of Pennsylvania had a reported use of 16,902 thousand barrels of distillate oil in the 

residential sector in 2006. Allegheny County, PA had 8,123 houses out of the state total of 

1,217,155 that use distillate oil as the primary heating fuel. This equates to a share of 0.67% of 

the distillate oil used for residential heating in the state. From Table 5, the emission factor for 

CO is 5 lb/thousand gallons. Because the emission factor is in lbs/thousand gallons, a 

conversion factor of 42 gallons per barrel is applied. 

AAlegheny = 16,902 thousand barrels × 8,123 houses / 1,217,155 houses) 

 × 42 gal / barrel 

 = 4,737.6 thousand gallons 

EmisAlegheny, CO = = 4,737.6 thousand gallons × 5 lb CO/ thousand gallons 
Page 98 

 = 23,688 lbs CO or 11.8 tons CO

3.2.3.5 Fossil Fuel Combustion – Residential - Kerosene 

a. Source Category Description 

Residential Kerosene Combustion is kerosene that is burned in residential housing. Common 

uses of energy associated with this sector include space heating, water heating, cooking, and 

running a wide variety of other equipment. 

The general approach to calculating emissions for this SCC is to take State Kerosene 

Consumption from the EIA and allocate it to the county level using methods described below. 

County-level kerosene consumption is multiplied by the emission factors to calculate emissions. 

For this source category, the following SCC was assigned: 

SCC Descriptor 1 Descriptor 3 Descriptor 6 Descriptor 8 

2104011000 Stationary Source 

Fuel Combustion 

Residential Kerosene Total: All Combustor Types

b. Activity Data 

The volume of kerosene consumed by residential combustion in the U.S. was used to estimate 

emissions. Kerosene consumption by energy use sector is presented in State Energy Data 2006 

Consumption tables published by the Energy Information Administration (EIA).1 Year 2006 

consumption data were used as a surrogate for 2008 emissions because year 2006 data were the 

latest data available when this inventory was prepared. 

State-level kerosene consumption was allocated to each county using the US Census Bureau’s 

2000 Census Detailed Housing Information.2

 These data include the number of housing units 

using a specific type of fuel for residential heating. State kerosene consumption was allocated to 

each county using the ratio of the number of houses burning kerosene in each county to the total 

number of houses burning kerosene in the State. 

c. Control Factors 

No control measures are assumed for this category. 

d. Emission Factors 

Emission factors for distillate oil were used for kerosene, but the distillate oil emission factors 

were multiplied by a factor of 135/140 to convert them for this use. This factor is based on the 

ratio of the heat content of kerosene (135,000 Btu/gallon) to the heat content of distillate oil 

(140,000 Btu/gallon).3

 Criteria pollutant emission factors are from AP-42. 4 Dioxin/furan and 

HAP emission factors are from “Documentation of Emissions Estimation methods for Year 2000 

and 2001 Mobile Source and Nonpoint Source Dioxin Inventories”5

 and “Documentation for the 

1999 Base Year Nonpoint Area Source National Emission Inventory for Hazardous Air 

Pollutants,”6

 respectively. Distillate sulfur content (0.30%) was used for kerosene as well.7 
Page 102 

e. Sample Calculations 

Emissions are calculated for each county using emission factors and activity as: 

 Ex,p = FCx × EFx,p

where: 

 Ex,p = annual emissions for fuel type x and pollutant p, 

 FCx = annual fuel consumption for fuel type x, 

 EFx,p = emission factor for fuel type x and pollutant p, 

And FCx = AState x (Hcounty / HState) 

where : 

 AState = State activity data from EIA 

 HCounty = number of houses in the county using kerosene as the primary heating fuel 

 HState = number of houses in the state using kerosene as the primary heating fuel 

Example: 

Using Allegheny County, PA as an example: 

The State of Pennsylvania had a reported use of 1,419.7 thousand barrels of kerosene in the 

residential sector in 2006. Allegheny County, PA had 8,123 houses out of the state total of 

1,217,155 that used kerosene as the primary heating fuel. This equates to a share of 0.67% of the 

kerosene used for residential heating in the state. From Table 1, CO Emission factor is 202.5 

lb/thousand barrels. 

ECO = 1,419.7 thousand barrels × (8,123 houses / 1,217,155 houses) 

× 202.5 lb/thousand barrels 

 = 1,918.6 lbs CO or 0.96 tons CO

3.2.3.6 Fossil Fuel Combustion – Residential – Natural Gas

a. Source Category Description 

Residential Natural Gas Combustion is natural gas that is burned to heat residential housing as 

well as in grills, hot water heaters, and dryers. 

The general approach to calculating emissions for this SCC is to take State Natural Gas 

Consumption from the EIA and allocate it to the county level using the methods described 

below. County level natural gas consumption is multiplied by the emission factors to calculate 

emissions. 

For this source category, the following SCC was assigned: 

SCC Descriptor 1 Descriptor 3 Descriptor 6 Descriptor 8 

2104006000 Stationary Source 

Fuel Combustion 

Residential Natural Gas Total: Boilers and IC 

Engines 

b. Activity Data 

The state-level volume of natural gas consumed by residential combustion in the United States 

was used to estimate emissions. Natural gas consumption by energy use sector was obtained 

from the State Energy Data 2006 Consumption tables published by the EIA.1 Year 2006 

consumption data were used as a surrogate for 2008 emissions because these data were the latest 

data available when this inventory was prepared. 

State-level natural gas consumption was allocated to each county using the US Census Bureau’s 

2000 Census Detailed Housing Information.2

 These data include the number of housing units 

using a specific type of fuel for residential heating. State natural gas consumption was allocated 

to each county using the ratio of the number of houses burning natural gas in each county to the 

total number of houses burning natural gas in the State. 

c. Control Factors 

No control measures are assumed for this category. 

d. Emission Factors 

Criteria pollutant emission factors for natural gas are from AP-42. 3 The ammonia emission 

factor is from EPA’s Estimating Ammonia Emissions from Anthropogenic Sources, Draft Final 

Report.

4

 HAP emission factors are from AP-42 and “Documentation for the 1999 Base Year 

Nonpoint Area Source National Emission Inventory for Hazardous Air Pollutants.”5

 According 

to AP-42 (maximum value provided)2

, natural gas has a heat content of 1,050 million BTU per 

million cubic feet. This value was required to convert those emission factors originally given in 

units “pounds per million Btu” to units “pounds per million cubic feet.” The grains of sulfur per 

million cubic feet are assumed to be 2000.6

 Some emission factors were revised based on 

recommendations by an ERTAC advisory panel composed of state and EPA personnel. 
Page 107 

County-level criteria pollutant and HAP emissions were calculated by multiplying the total 

natural gas consumed in each county per year by an emission factor. Table 1 provides a 

summary of the pollutants, pollutant codes, and emissions factors for residential combustion of 

natural gas. 

e. Sample Calculations 

Emissions are calculated for each county using emission factors and activity as: 

 Ex,p = FCx × EFx,p

where: 

 Ex,p = annual emissions for fuel type x and pollutant p, 

 FCx = annual fuel consumption for fuel type x, 

 EFx,p = emission factor for fuel type x and pollutant p, 

And FCx = AState x (Hcounty / HState) 

where : 

 AState = State activity data from EIA 

 HCounty = number of houses in the county using natural gas as the primary heating fuel 

 HState = number of houses in the state using natural gas as the primary heating fuel 

Example: 

Using Allegheny County, PA as an example: 

The State of Pennsylvania had a reported use of 205,812 million cubic feet of natural gas in the 

residential sector in 2006. Allegheny County, PA had 474,292 houses out of the state total of 

2,452,941 that use natural gas as the primary heating fuel. This equates to a share of 19.34% of 

the natural gas used for residential heating in the state. From Table 1, CO emission factor is 40 

lb/million ft3

.

ECO= 205,812 million ft3

 × (474,292 houses / 2,452,941 houses) × 40 lb CO/ million ft3 

= 1,591,803 lb CO or 795.9 ton CO

b. Activity Data 

Annual Value of Construction Put in Place in the U.S1

 has the 2008 National Value of Nonresidential construction. The national value of non-residential construction put in place (in 

millions of dollars) was allocated to counties using county-level non-residential construction 

(NAICS Code 2362) employment data obtained from County Business Patterns2 (CBP). Because 

some counties employment data was withheld due to privacy concerns, the following procedure 

was adopted: 

State totals for the known county level employees was subtracted from the number of employees 

reported in the state level version of CBP. This results in the total number of withheld employees 

in the state. 

A starting guess of the midpoint of the range code was used (so for instance in the 1-19 

employees range, a guess of 10 employees would be used) and a state total of the withheld 

counties was computed. 

A ratio of guessed employees (Step 2) to withheld employees (Step 1) was then used to adjust 

the county level guesses up or down so the state total of adjusted guesses should match state total 

of withheld employees (Step 1) 

In 1999 a figure of 2 acres/$106

 was developed. The Bureau of Labor Statistics Producer Price 

Index3

 lists costs of the construction industry from 1999-2007. 

2007 acres per $106

 = 1999 acres per $106 x (1999 PPI / 2007 PPI) 

=2 acres/$106 (132.9 / 204.3) 

= 1.301 acres per $106 

c. Emission Factors 

Initial PM10 emissions from construction of non-residential buildings are calculated using an 

emission factor of 0.19 tons/acre/month. The duration of construction activity for non-residential 

construction is assumed to be 11 months. 

Regional variances in construction emissions are corrected using soil moisture level and silt 

content. These correction parameters are applied to initial PM10 emissions from non-residential 

construction to develop the final emissions inventory. 
Page 111 

To account for the soil moisture level, the PM10 emissions are weighted using the 30-year 

average precipitation-evaporation (PE) values from Thornthwaite’s PE Index. Average 

precipitation evaporation values for each State were estimated based on PE values for specific 

climatic divisions within a State. These values range from 7 to 41. 

To account for the silt content, thePM10 emissions are weighted using average silt content for 

each county. A data base containing county-level dry silt values was complied. These values 

were derived by applying a correction factor developed by the California Air Resources Board to 

convert wet silt values to dry silt values.7

The equation for PM10 emissions corrected for soil moisture and silt content is: 

Corrected E Initial

PE

S

PM PM E 10 10  

24

9%

where: Corrected EPM10 = PM10 emissions corrected for soil moisture and silt content, 

 PE = precipitation-evaporation value for each State, 

 S = % dry silt content in soil for area being inventoried. 

Once PM10 adjustments have been made, PM25 emissions are set to 10% of PM10 

d. Control Factors 

No control measures are assumed for this category.

e. Example Calculation 

EmissionsPM10 = NSpending x (Empcounty / EmpNational) x Apd x EFAdj

 Where NSpending = National spending 

 Empcounty = county level employment data 

 EmpNational = National level employment data 

 Apd = Acres per million dollars 

 EFAdj = Adjusted PM10 emission factor

b. Activity Data

There are really two types of activity calculations going on for this SCC, acres of surface soil 

disturbed, and volume of soil removed for basements 

Surface Soil disturbed 

The US Census Bureau has 2008 data for Housing Starts - New Privately Owned Housing Units 

Started1 which provides regional level housing starts based on the groupings of 1 unit, 2-4 units, 

5 or more units. A consultation with the Census Bureau in 2002 gave a breakdown of 

approximately 1/3 of the housing starts being for 2 unit structures, and 2/3 being for 3 and 4 unit 

structures. The 2-4 unit category was then divided into 2-units, and 3-4 units based on this ratio. 

To get the number of structures for each grouping, the 1unit category was divided by 1, 2 unit 

category was divided by 2, and the 3-4 unit category was divided by 3.5. The 5 or more unit 

category listed may be made up of more than one structure. New Privately Owned Housing Units 

Authorized Unadjusted Units2

 gives a conversion factor to determine the ratio of structures to 

units in the 5 or more unit category. For example if a county has one 40unit apartment building, 

the ratio would be 40/1. If there are 5 different 8 unit buildings in the same project, the ratio 

would be 40/5. Structures started by category are then calculated at a regional level. The table 

Annual Housing Units Authorized by Building Permit3

 has 2007 data at the county level to 

allocate regional housing starts to the county level. This results in county level housing starts by 

number of units. The following surface areas were assumed disturbed for each unit type: 

Table 1: Surface Soil removed per unit type 

1-Unit 1/4 acre/structure

2-Unit 1/3 acre/structure

Apartment 1/2 acre/structure 

The 3-4 unit category was considered to be an apartment. Multiplication of housing starts to soil 

removed results in number of acres disturbed for each unit category. 
Page 113 

Basement soil removal 

To calculate basement soil removal, 2007 Characteristics of New Houses4 is used to estimate the 

percentage of 1 unit structures that have a basement (on the regional level). The county level 

estimate of number of 1 unit starts is multiplied by the percent of 1 unit houses in the region that 

have a basement to get the number of basements in a county. Basement volume is calculated by 

assuming a 2000 square foot house has a basement dug to a depth of 8 feet (making 1600 ft3 per 

basement). An additional 10% is added for peripheral dirt bringing the total to 1760 ft3 per 

basement. 

c. Emission Factors 

Initial PM10 emissions from construction of single family, two family, and apartments structures 

are calculated using the emission factors given in Table 2. The duration of construction activity 

for houses is assumed to be 6 months and the duration of construction for apartments is assumed 

to be 12 months. 

Table 2. Emission Factors for Residential Construction

Type of Structure Emission Factor Duration of

Apartments 0.11 tons PM10/acre-month 12 months

Basements 

0.011 tons PM10/acre-month 6 months

yards 

Regional variances in construction emissions are corrected using soil moisture level, silt content, 

and control efficiency. These correction parameters are applied to initial PM10 emissions from 

residential construction to develop the final emissions inventory. 

To account for the soil moisture level, the PM10 emissions are weighted using the precipitationevaporation (PE) values from Thornthwaite’s PE Index. Average precipitation evaporation 

values for each State were estimated based on PE values for specific climatic divisions within a 

State. These values range from 7 to 41. 

 

To account for the silt content, thePM10 emissions are weighted using average silt content for 

each county. A data base containing county-level dry silt values was complied. These values 
Page 114 

were derived by applying a correction factor developed by the California Air Resources Board to 

convert wet silt values to dry silt values.5 

The equation for PM10 emissions corrected for soil moisture and silt content

where: Corrected EPM10 = PM10 emissions corrected for soil moisture and silt content,

Once PM10 adjustments have been made, PM25 emissions are set to 20% of PM10 

d. Control Factors 

No control measures are assumed for this category.

PM10 Emissions = ∑( Aunit x Tconstruction x EFunit ) x AdjPM

Where Aunit = HSUnit x SMUnit

HSUnit = Regional Housing Starts x (county building permits/Regional building permits) 

SMUnit = Area or volume of soil moved for the given unit type 

TConstruction = Construction time (in months) for given unit type 

EFUnit = Unadjusted emission factor for PM10 for the given unit type 

AdjPM = PM Adjustment factor

The Federal Highway Administration has Highway Statistics, Section IV - Highway Finance, 

Table SF-12A, State Highway Agency Capital Outlay1 for 2006 which outlines spending by state 

in several different categories. For this SCC, the following columns are used: New Construction, 

Relocation, Added Capacity, Major Widening, and Minor Widening. These columns are also 

differentiated according to the following six classifications: 

1. Interstate, urban 

2. Interstate, rural 

3. Other arterial, urban 

4. Other arterial, rural 

5. Collectors, urban 

6. Collectors, rural 

The State expenditure data are then converted to new miles of road constructed using $/mile 

conversions obtained from the North Carolina Department of Transportation (NCDOT) in 2000. 

A conversion of $4 million/mile is applied to the interstate expenditures. For expenditures on 

other arterial and collectors, a conversion factor of $1.9 million/mile is applied, which 

corresponds to all other projects. 

The new miles of road constructed is used to estimate the acreage disturbed due to road 

construction. The total area disturbed in each state is calculated by converting the new miles of 

road constructed to acres using an acres disturbed/mile conversion factor for each road type as 

given in the table below:

Residential building starts2 are used to allocate the state-level acres disturbed by road 

construction to the county. A ratio of the number of building starts in each county to the total 

number of building starts in each state is applied to the state-level acres disturbed to estimate the 

total number of acres disturbed by road construction in each county. 

c. Emission Factors 

Initial PM10 emissions from construction of roads are calculated using an emission factor of 0.42 

tons/acre/month. Since most road construction consists of grading and leveling of land, the 

higher emission factor more accurately reflects the high level of cut and fill activity that occurs at 

road construction sites. The duration of construction activity for road construction is assumed to 

be 12 months. 

Regional variances in construction emissions are corrected using soil moisture level, silt content, 

and control efficiency. These correction parameters are applied to initial PM10 emissions from 

non-residential construction to develop the final emissions inventory. 

To account for the soil moisture level, the PM10 emissions are weighted using the precipitationevaporation (PE) values from Thornthwaite’s PE Index. Average precipitation evaporation 

values for each State were estimated based on PE values for specific climatic divisions within a 

State. These values range from 7 to 41. 

To account for the silt content, thePM10 emissions are weighted using average silt content for 

each county. A data base containing county-level dry silt values was complied. These values 

were derived by applying a correction factor developed by the California Air Resources Board to 

convert wet silt values to dry silt values.

3.2.3.10 Agricultural Production – Livestock 

a. Source Category Description 

Livestock refers to domesticated animals intentionally reared for the production of food, fiber, or 

other goods or for the use of their labor. The definition of livestock in this category includes beef 

cattle, dairy cattle, ducks, geese, goats, horses, poultry, sheep, and swine. 

The approach to calculating emissions for the assigned SCCs consisted of four general steps, as 

follows: 

 Determining county-level population of animals for 2007. 

 For beef, dairy, poultry, and swine, apportioning animal populations to a manure 

management train (MMT) for each county. Animal populations for ducks, geese, 

goats, horses, and sheep were not apportioned to MMTs. 

 Modifying the emission factor files provided with the CMU Ammonia Model v. 

3.6 to ensure that every county had an assigned emission factor.1

 Using the CMU Ammonia Model v. 3.6 to calculate ammonia emissions based on 

the updated county-level animal populations and emission factors. 

For this source category, the following SCCs were assigned:

b. Activity Data 

County-level animal numbers for 2007 were obtained from the U.S. Department of Agriculture’s 

2007 Census of Agriculture report.2

 For Virginia, the county-level census data includes animal 

populations from Virginia’s 39 independent cities. For some counties and states, census data was 

withheld to avoid disclosing data for individual farms. However, the total national-level animal 

numbers and most state-level animal numbers for each livestock type reported in the Census 

include those animal numbers not disclosed at the county-level. When available, state-level 

animal numbers from the USDA NASS online database were used for states with undisclosed 

animal numbers in the 2007 Census of Agriculture.3

 To determine the total number of 

undisclosed animals, disclosed county-level animal numbers for each livestock type were 

summed and subtracted from the total state animal numbers. The total undisclosed animal 

population for a specific livestock type was then allocated to those counties reporting 

undisclosed data based on the number of farms raising that livestock in each county.2

 If the statelevel data was undisclosed and not available in the NASS database, then national animal 

numbers were used to determine undisclosed state numbers. The disclosed county-level data was 

then summed and subtracted from the state-level data to determine animal numbers not disclosed 

at the county-level. These numbers were then allocated to those counties reporting undisclosed 

data based on the number of farms raising that livestock in each county. 

County-level animal numbers were apportioned to manure management trains. A MMT consists 

of an animal confinement area (e.g., drylot, pasture, flush, scrape); components used to store, 
Page 122 

process, or stabilize the manure (e.g., anaerobic lagoons, deep pits); and a land application site 

where manure is used as a fertilizer source.4

 The apportionment was based on county-level MMT 

percentages derived from the CMU Ammonia Model. For each livestock type, the county-level 

number of animals in each MMT was divided by the total county-level animal population for that 

livestock type to calculate the percentage of total animals managed by each MMT. In cases 

where the county-level numbers were zero in the 2002 CMU Ammonia Model input files, the 

county was assigned state-level MMT percentages. The county-level animal population for each 

livestock type from the 2007 Census of Agriculture was multiplied by the MMT percentages to 

determine the total number of animals in each MMT in 2007. Animal populations for ducks, 

geese, goats, horses, and sheep were not apportioned to MMTs. 

Cattle reported as “Other Cattle” in the 2007 Census of Agriculture were divided between dairy 

cattle and beef cattle at the county-level using percent allocations derived from county-level 

dairy and beef cattle reported in the 2007 Census of Agriculture and corrected for undisclosed 

data. The animal numbers from “Other Cattle” apportioned to dairy and beef cattle were used to 

create the Dairy Cattle – Composite and Beef Cattle – Composite activity input files for the 

CMU Ammonia Model. 

County-level pullet numbers reported in the 2007 Census of Agriculture were used to create the 

Poultry – Composite activity input file for the CMU Ammonia Model. 

c. Emission Factors 

The emission factor for the poultry composite categories was obtained from an EPA report and is 

reported in Table 1 below.4

 The county-level emission factors for the beef composite and dairy 

composite categories were developed using beef and dairy cattle emission factors provided with 

the 2002 CMU Model. Specifically, weighted average emission factors were calculated based on 

the number of beef or dairy cattle in each MMT from the 2002 CMU Model activity files and the 

emission factor assigned to each MMT. All other emission factors were provided with the CMU 

Ammonia Model v.3.6. The emission factors for some counties in the CMU Ammonia Model 

files were zero. To ensure that all counties with animal populations were assigned emissions 

factors, the emission factor input files provided with the CMU Ammonia Model were modified. 

For all counties with an emission factor of zero, the emission factor was replaced with the state 

average emission factor. If all counties in the state had emission factors of zero, then the county 

emission factor was replaced with the national average emission factor. The state average 

emission factor was calculated by summing the counties with non-zero emission factors in the 

state and dividing the total by the number of counties in that state with non-zero emission 

factors. The national average emission factor was calculated by summing the counties with nonzero emission factors in the nation and dividing the total by the number of counties in the nation 

with non-zero emission factors. 

d. Emissions 
Page 123 

The livestock activity files provided with the CMU Ammonia Model v.3.6 were replaced with 

the updated county-level animal population files and modified emissions files. County-level 

ammonia emissions were then calculated by running the model. 

e. Sample Calculations 

Allocation of Undisclosed Data 

From the 2007 Census of Agriculture, the total national number of beef cattle in Alabama is 

678,949. The total number of beef cattle disclosed at the county-level is 388,827. 

Total number of beef cattle undisclosed at the county-level = 678,949 - 338,827 = 

340,122 

From the 2007 Census of Agriculture, the total number of farms in Alabama not disclosing beef 

cattle numbers is 10,518. 

 Average beef cattle per farm not disclosing data = 340,122 / 10,518 = 32.3 

For 2007, Baldwin County, Alabama beef cattle data was not disclosed. The total number of 

farms with beef cattle in Baldwin County is 343. 

 Estimated number of beef cattle in Baldwin County = 32.3 x 343 = 11,092 

Manure Management Train 

From the 2002 CMU Ammonia Model input files, Chilton County, Alabama had 79 beef cattle 

under drylot management and 18,900 beef cattle under pasture management in 2002. 

 Total beef cattle = 79 + 18,900 = 18,979 

 % of beef cattle under drylot management = 79 / 18,979 = 0.42 

 % of beef cattle under pasture management = 18,900 / 18,979 = 99.58 

The total number of beef cattle for Chilton County reported in the 2007 Census of Agriculture is 

7,939. 

 Number of beef cattle under drylot management in 2007 = 7,939 x 0.0042 = 33 

Number of beef cattle under pasture management in 2007 = 7,939 x 0.9958 = 7,906 

“Other Cattle” 

For Clay County, Alabama, the 2007 Census of Agriculture reports the number of “Other Cattle” 

as 5,471, the number of dairy cattle as 216, and the number of beef cattle as 9,096. 
Page 124 

 Total beef and dairy cattle reported = 216 + 9,096 = 9,312 

% of other cattle assigned to beef cattle = (9,096/9,312)*100 = 97.68 

% of other cattle assigned to dairy cattle = (216/9,312)*100 = 2.32 

Other cattle allocated to beef cattle = 5,471 x .9768 = 5,344 

Other cattle allocated to dairy cattle = 5,471 x 0.0232 = 127

b. Activity Data 

Activity data was collected from the US Census Bureau’s county level population estimates for 

July 1, 2008.1 

c. Control Factors 

No controls were assumed for this category. 

d. Emission Factors 

Emission factors were developed and reviewed by an ERTAC advisory panel composed of state 

and EPA personnel (Contact: Roy Huntley, huntley.roy@epa.gov). They were created by taking 

2002 emissions in the NEI and dividing by the 2002 population to develop per capita emission 

factors. These emission factors are listed in Table 1. 

e. Sample Calculations 

Emissions are calculated for each county using emission factors and activity as: 

 Ex,p = Ax × EFx,p
Page 128 

where: 

 Ex,p = annual emissions for category x and pollutant p; 

 Ax = population data associated with category x; 

 EFx,p = emission factor for category x and pollutant p. 

Example: 

Using conveyorized charbroiling in Allegheny County, PA as an example: 

According to the US Census Bureau, population on July 1, 2008 is 1,215,103 

The emission factor for VOC is 0.01205 lb/person 

 EVOC= 1,215,103 people × 0.01205 lb VOC/ person

 = 14,650 lb VOC or 7.3 ton VOC

3.2.3.12 Asphalt Paving – Cutback 

a. Source Category Description 

Asphalt paving is the process of applying asphalt concrete to seal or repair the surface of roads, 

parking lots, driveways, walkways, or airport runways. Asphalt concrete is a composite material 

comprised of a binder and a mineral aggregate. The binder, referred to as asphalt cement, is a 

byproduct of petroleum refining and contains the semi-solid residual material left after the more 

volatile chemical fractions have been distilled off.1 

Asphalt cements thinned with petroleum distillates are known as cutback asphalts. The primary 

uses of cutback asphalt include tack and seal operations, priming roadbeds, and paving operations 

for pavements up to several inches thick. Cut-back asphalt is produced by thinning the binder in a 

diluent containing 25 to 45 percent petroleum distillates by volume prior to mixing with the 

aggregate. This reduces the viscosity of the asphalt making it easier to work with the mixture. 

Emissions from cutback asphalt result from the evaporation of VOCs and HAPS after the mixture 

is laid down. Of all asphalt types, cutback asphalt has the highest diluent content and, as a result, 

emits the highest levels of VOCs per ton used. The timeframe and quantity of VOC and HAP 

emissions depend on the type and the quantity of organic solvent used as a diluent. 

 For this source category, the following SCC was assigned: 

SCC SCC Level 1 SCC Level 2 SCC Level 3 SCC Level 4 

2461021000 Solvent Utilization Miscellaneous Nonindustrial: Commercial Cutback Asphalt Total: All Solvent 

Types 

The general approach to calculating emissions from cutback asphalt paving is to multiply the 

estimated county-level cutback asphalt usage by emission factors for VOCs and HAPs. 

b. Activity Data 

State-level cutback asphalt usage in 2008 was obtained from the Asphalt Institute’s 2008 Asphalt 

Usage Survey.

2

 State-level data were allocated to county-level according to the fraction of paved 

road vehicle miles traveled (VMT) in each county. 

Total annual VMT estimates by State and roadway class were obtained from the Federal 

Highway Administration’s (FHWA) annual Highway Statistics report.3 Paved road VMT was 

calculated by subtracting the State/roadway class unpaved road VMT from total State/roadway 

class VMT. State-level paved road VMT was spatially allocated to counties according to the 

fraction of total VMT in each county for the specific roadway class as shown by the following 

equation: 

VMTx,total = ∑VMTST,y * VMTx,y / VMTST,y

where: VMTx,total = VMT (million miles) in county x on all paved roadways 

VMTST,y = paved road VMT for the entire State for roadway class y 

VMTx,y = total VMT (million miles) in county x and roadway class y 
Page 133 

VMTST,y = total VMT (million miles) in entire State for roadway 

class y 

The county-level total VMT by roadway class used in this calculation was previously developed 

by E.H. Pechan and Associates, Inc. to support the onroad national emissions inventory.4 

c. Emission Factors 

Emission factors for cutback asphalt usage were obtained from the Technical Report Series 

produced by the U.S. EPA’s Emission Inventory Improvement Program and are reported in Table 

1 below.1

d. Emissions 

Emissions were calculated by multiplying the county-level asphalt usage (barrels) by the emission 

factors listed in Table 1 and then dividing by 2000 to convert pounds to tons. 

Emissionsx,y = (Asphalt Usagex * EFy) / 2000 

where: Emissionsx,y = emissions (tons) of pollutant y in county x 

 Asphalt Usagex = cutback asphalt (barrels) used in county x 

 EFy = emission factor for pollutant y 

To convert tons of asphalt reported in the 2008 Asphalt Usage Survey to barrels, it was assumed 

that the density of asphalt is similar to that of water, 8.34 lbs/gal, and that one barrel equals 42 

gallons. 

Barrels of Asphalt = (tons of asphalt * 2000 lbs / 8.34 lbs/gal) / 42 gal/barrel 

Note that one barrel of asphalt weights approximately 350 pounds. 

e. Sample Calculation 

VOC emissions from cutback asphalt usage in Autauga County, Alabama: 

From the 2008 Asphalt Usage Survey, the state of Alabama used 1,728 tons of cutback asphalt in 

2008. The fraction of paved road VMT traveled in Autauga County is 497 million miles divided 

by 53,633 million miles which equals 0.0093. 

 Asphalt UsageAutauga = ((1,728 tons * 2000 lbs / 8.34 lbs/gal) / 42 gal/barrel) * 0.0093 

 Asphalt UsageAutauga = 91.41 barrels 

 VOC EmissionsAutauga = (91.41 barrels * 88 lbs/barrel) / 2000 lbs/ton 

VOC EmissionsAutauga = 4.022 tons

a. Source Category Description 

Asphalt paving is the process of applying asphalt concrete to seal or repair the surface of roads, 

parking lots, driveways, walkways, or airport runways. Asphalt concrete is a composite material 

comprised of a binder and a mineral aggregate. The binder, referred to as asphalt cement, is a 

byproduct of petroleum refining and contains the semi-solid residual material left after the more 

volatile chemical fractions have been distilled off.1 

Asphalt cements thinned with water and an emulsifying agent are known as emulsified asphalts. 

This thinning reduces the viscosity of the asphalt making it easier to work with the mixture. The 

primary uses of emulsified asphalt include tack and seal operations, priming roadbeds, and paving 

operations for pavements up to several inches thick. 

Emulsified asphalt may contain up to 12 percent organic solvents by volume.1 Emissions from 

emulsified asphalt result from the evaporation of VOCs after the mixture is laid down. Compared 

to cutback asphalt, emulsified asphalt has lower VOCs emissions per ton used.

 EFy = emission factor for pollutant y 

To convert tons of asphalt reported in the 2008 Asphalt Usage Survey to barrels, it was assumed 

that the density of asphalt is similar to that of water, 8.34 lbs/gal, and that one barrel equals 42 

gallons. 

Barrels of Asphalt = (tons of asphalt * 2000 lbs / 8.34 lbs/gal) / 42 gal/barrel 

Note that one barrel of asphalt weights approximately 350 pounds. 

e. Sample Calculation 

VOC emissions from emulsified asphalt usage in Autauga County, Alabama: 

From the 2008 Asphalt Usage Survey, the state of Alabama used 18,988 tons of emulsified asphalt 

in 2008. The fraction of paved road VMT traveled in Autauga County is 497 million miles 

divided by 53,633 million miles which equals 0.0093. 

 Asphalt UsageAutauga = ((18,988 tons * 2000 lbs / 8.34 lbs/gal) / 42 gal/barrel) * 0.0093 

 Asphalt UsageAutauga = 1,004 barrels 

 VOC EmissionsAutauga = (1,004 barrels * 9.2 lbs/barrel) / 2000 lbs/ton 

VOC EmissionsAutauga = 4.62 tons

3.2.3.14 Gasoline Distribution – Portable Fuel Containers

a. Source Category Description 

Portable fuel containers (PFCs, or gas cans) are consumer products used to refuel a wide variety 

of gasoline-powered equipment. 

The general approach to calculating emissions for this SCC is to take the inventories already 

prepared by the EPA for 2002 and 2010 and apply a linear fit between to get 2008 emissions. 

For this source category, the following SCCs were assigned:

b. Activity Data 

Activity data for the 2002 and 2010 inventories were developed using EPA’s Nonroad Model 

which uses a variety of variables like equipment size, equipment population, equipment age, 

RVP, and air temperature to estimate activity. 
Page 139 

c. Control Factors 

There are at least 15 states which have enacted or are considering rules for PFCs. Due to the 

complexities in calculating emissions, these rules have already been accounted for in the 

emissions, but will not be listed in the control table. 

d. Emission Factors 

Section 2.2 of the EPA PFC report details emission factors used for each of the activities 

associated with PFCs. 

e. Sample Calculations 

Emissions are calculated in the formula 

 EmisCounty, Pollutant = m x yeardiff + Emis2002 

where: 

 m = (Emis2010 – Emis2002) / (2010 – 2002) 

Example: 

Using SCC 2501011011 in Allegheny County PA as an example: 

 Emis2010 = 60.7 tons VOC 

 Emis2002 = 181.7 tons VOC 

 m = (60.7 – 181.7) / (2010 – 2002) = -15.125 

 EmisAlegheny, VOC = -15.125 x (2008-2002) + 181.7 

 = 90.95 tons VOC

3.2.3.15 Aviation Gasoline Distribution – Stage I 

a. Source Category Description 

Aviation gasoline (also called “AvGas”) is the only aviation fuel that contains tetraethyl lead 

(TEL) as a knock-out component for small reciprocating, piston-engine crafts in civil aviation.1

 

Commercial and military aviation rarely use this fuel. AvGas is shipped to airports and is filled 

into bulk terminals, and then into tanker trucks. These processes fall under the definition of 

stage I, displacement vapors during the transfer of gasoline from tank trucks to storage tanks, and 

vice versa. These processes are subject to EPA’s maximum available control technology 

(MACT) standards for gasoline distribution.2

Gasoline 

Stage 1: Total 

b. Activity Data 

The amount of AvGas consumed was obtained from the Petroleum Supply Annual for designated 

Petroleum Administration Districts, or PADs.3 A nationwide total of 5,603,000 barrels of AvGas 

were consumed in 2008 (Table 1).3 This information was used to calculate national-level 

emissions estimates for one criteria pollutant and ten hazardous air pollutants (HAPs). 

Assumptions for bulk plant processes are summarized in Table 2. 

c. Emission Factors 

Emission factors were provided by ESD and EIG publications (Tables 3 and 4).1,4,5,6

d. Emissions 

In general, national-level emissions were calculated by multiplying AvGas consumption by the 

appropriate emission factors and then summing emissions. The national-level emission estimates 

were first allocated based on consumption reported for each PAD, and then allocated to the 

counties within the PADs based on 2008 Landing-Take Off (LTO) data for general aviation 

flights.7

 General aviation flights were used in this allocation because they are the primary 

consumers of AvGas. 

There are five PADs across the United States3

PAD 1 comprises seventeen states plus the District of Columbia along the Atlantic Coast; 

PAD 2 comprises fifteen states in the Midwest; 

PAD 3 comprises six states in South Central U.S.; 
Page 141 

PAD 4 comprises five states in the Rocky Mountains; and 

PAD 5 comprises seven states along the West Coast.

e. Sample Calculations 

National-Level Calculations 

Amount of AvGas consumed in 2008 (barrels) = 5,603,000 

Conversion: 1 barrel = 42 gallons

1 gallon = 3.78 liters

1 kg = 2.205 lb 

1 kg = 1,000,000 mg 

1 ton = 2000 lb

Step 1 - Convert AvGas consumption into gallons using conversion factors.

 Amount of AvGas consumed in 2008 (gallons) = 5,603,000 barrels * 42 gallons/barrel 

 Amount of AvGas consumed in 2008 (gallons) = 235,326,000 

Step 2 - Use the gallons of AvGas consumed and apply the non-fugitive VOC emission factors in 

Table 3 to calculate non-fugitive VOC estimates. 

Unloading/Tank Filling: tank fill VOC emissions = 0.009021383 LB/GAL * 

235,326,000 GAL / 2,000 LB/TON 

Unloading/Tank Filling: tank fill VOC emissions = 1,061.48 tpy

GAL * / 2,000 LB/TON 

Storage Tank - Breathing losses VOC Emissions = 199.33 tpy 

Total non-fugitive VOC emissions = 1,061.48 tpy + 424.20 tpy + 1,212.70 tpy + 199.33 

tpy = 2,897.72 tpy 

Step 3 - Use the assumptions in Table 2 and the fugitive VOC emission factors in Table 3 to 

generate fugitive VOC emissions.

AvGas - Fugitive from valves VOC Emissions = (# Bulk Plant 

Equivalents)*(#valves/plant)*EF*days 

AvGas - Fugitive from valves VOC Emissions = (2442 plants) * (50 valves/plant) * 

(0.573201882 LB/valve/day)* 300 days / 2,000 LB/TON 

AvGas - Fugitive from valves VOC Emissions = 10,498.19 tpy 

AvGas - Fugitive from pumps VOC Emissions = (# Bulk Plant 

Equivalents)*(#pumps/plant)* (#seals/pump) * EF * days 

AvGas - Fugitive from pumps VOC Emissions = (2442 plants) * (2 pumps/plant) * (4 

seals/pump) * (5.952481079 LB/seal/day)* 300 days / 2,000 LB/TON 

AvGas - Fugitive from pumps VOC Emissions = 17,443.15 tpy 

Total fugitive VOC emissions = 10,498.19 tpy + 17,443.15 tpy 

Total fugitive VOC emissions = 27,941.34 tpy 

Step 4 - Sum the fugitive and non-fugitive VOC emissions together for total VOC emissions. 

Total VOC emissions = 2,897.72 tpy + 27,941.34 tpy = 30,839.06 tpy 

Step 5 - Apply the speciation emission factors in Table 4 for tetraethyl lead, 2,2,4-

trimethylpentane, benzene, cumene, ethylbenzene, hexane, naphthalene, toluene, and 

xylene to calculate HAP emissions. 

Tetraethyl Lead emissions = 30,839.06 tpy VOC * 9.78 E-6 = 0.30 tpy 

2,2,4-Trimethylpentane emissions = 30,839.06 tpy VOC * 0.008 = 246.71 tpy 

Benzene emissions = 30,839.06 tpy VOC * 0.009 = 277.55 tpy 

Cumene emissions = 30,839.06 tpy VOC * 0.0001 = 3.08 tpy 

Ethylbenzene emissions = 30,839.06 tpy VOC * 0.0010 = 30.84 tpy 

Hexane emissions = 30,839.06 tpy VOC * 0.0160 = 493.43 tpy 

Naphthalene emissions = 30,839.06 tpy VOC * 0.0005 = 15.42 tpy 

Toluene emissions = 30,839.06 tpy VOC * 0.0130 = 400.91 tpy 

Xylene emissions = 30,839.06 tpy VOC * 0.005 = 154.20 tpy 
Page 143 

Step 6 - Use the ethylene dichloride emission factor in Table 4 to calculate ethylene dichloride 

emissions.

Ethylene dichloride emissions = 235,326,000 GAL * 2.167E-6 LB/GAL * TON/2000 LB 

= 0.25 tpy

Amount of AvGas consumed in 2008 (barrels) = 5,603,000 

Conversion: 1 barrel = 42 gallons

1 gallon = 3.78 liters

1 kg = 2.205 lb 

1 kg = 1,000,000 mg 

1 ton = 2000 lb

Step 1 - Convert AvGas consumption into gallons using conversion factors.

 Amount of AvGas consumed in 2008 (gallons) = 5,603,000 barrels * 42 gallons/barrel 

 Amount of AvGas consumed in 2008 (gallons) = 235,326,000 

Step 2 - Use the gallons of AvGas consumed and apply the refueling VOC emission factors from 

Table 2 to first calculate refueling VOC estimates. 

AvGas Refueling VOC emissions = (1.36 E-2 LB/gal AvGas) * 235,326,000 gallons * 1

3.2.3.17 Open Burning – Land Clearing Debris 

a. Source Category Description 

Open burning of land clearing debris is the purposeful burning of debris, such as trees, shrubs, 

and brush, from the clearing of land for the construction of new buildings and highways. Criteria 

air pollutant (CAP) and hazardous air pollutant (HAP) emission estimates from open burning of 

land clearing debris are a function of the amount of material or fuel subject to burning per year. 

For this source category, the following SCC was assigned: 

SCC SCC Level 1 SCC Level 2 SCC Level 3 SCC Level 4 

2610000500 Waste Disposal, 

Treatment, and Recovery 

Open Burning All Categories Land Clearing Debris 

(use 28-10-005-000 

for Logging Debris 

Burning) 

b. Activity Data 

The amount of material burned was estimated using the county-level total number of acres 

disturbed by residential, non-residential, and road construction. County-level weighted loading 

factors were applied to the total number of construction acres to convert acres to tons of available 

fuel. 

Acres Disturbed from Residential Construction 

The US Census Bureau has 2008 data for Housing Starts - New Privately Owned Housing Units 

Started1 which provides regional level housing starts based on the groupings of 1 unit, 2-4 units, 

5 or more units. A consultation with the Census Bureau in 2002 gave a breakdown of 

approximately 1/3 of the housing starts being for 2 unit structures, and 2/3 being for 3 and 4 unit 

structures. The 2-4 unit category was divided into 2-units, and 3-4 units based on this ratio. To 

determine the number of structures for each grouping, the 1 unit category was divided by 1, the 2 

unit category was divided by 2, and the 3-4 unit category was divided by 3.5. The 5 or more unit 

category may be made up of more than one structure. New Privately Owned Housing Units 

Authorized Unadjusted Units2

 gives a conversion factor to determine the ratio of structures to 

units in the 5 or more unit category. For example if a county has one 40 unit apartment building, 

the ratio would be 40/1. If there are 5 different 8 unit buildings in the same project, the ratio 

would be 40/5. Structures started by category are then calculated at a regional level. The table 

Annual Housing Units Authorized by Building Permit3

 has 2007 data at the county level to 

allocate regional housing starts to the county level. This results in county level housing starts by 

number of units. The following surface areas were assumed disturbed for each unit type: 

Table 1: Surface Acres Disturbed per Unit Type 

1-Unit 1/4 acre/structure

2-Unit 1/3 acre/structure

Apartment 1/2 acre/structure 
Page 151 

The 3-4 unit and 5 or more unit categories were considered to be apartments. Multiplication of 

housing starts to surface acres disturbed results in total number of acres disturbed for each unit 

category. 

Acres Disturbed from Non-Residential Construction 

Annual Value of Construction Put in Place in the U.S4 has the 2008 National Value of Nonresidential construction. The national value of non-residential construction put in place (in 

millions of dollars) was allocated to counties using county-level non-residential construction 

(NAICS Code 2362) employment data obtained from County Business Patterns5 (CBP). Because 

some counties employment data was withheld due to privacy concerns, the following procedure 

was adopted: 

1. State totals for the known county level employees were subtracted from the number of 

employees reported in the state level version of CBP. This results in the total number of 

withheld employees in the state. 

2. A starting guess of the midpoint of the range code was used (so for instance in the 1-19 

employees range, a guess of 10 employees would be used) and a state total of the 

withheld counties was computed. 

3. A ratio of guessed employees (Step 2) to withheld employees (Step 1) was then used to 

adjust the county level guesses up or down so the state total of adjusted guesses should 

match state total of withheld employees (Step 1) 

In 1999 a figure of 2 acres/$106

 was developed. The Bureau of Labor Statistics Producer Price 

Index6 lists costs of the construction industry from 1999-2007. 

 2007 acres per $106 = 1999 acres per $106 x (1999 PPI / 2007 PPI) 

 = 2 acres/$106 (132.9 / 204.3) 

 = 1.301 acres per $106 

Acres Disturbed by Road Construction 

The Federal Highway Administration has Highway Statistics, Section IV - Highway Finance, 

Table SF-12A, State Highway Agency Capital Outlay7 for 2006 which outlines spending by state 

in several different categories. For this SCC, the following columns are used: New Construction, 

Relocation, Added Capacity, Major Widening, and Minor Widening. These columns are also 

differentiated according to the following six classifications: 

1. Interstate, urban 

2. Interstate, rural 

3. Other arterial, urban 

4. Other arterial, rural 

5. Collectors, urban 

6. Collectors, rural 
Page 152 

The State expenditure data are then converted to new miles of road constructed using $/mile 

conversions obtained from the North Carolina Department of Transportation (NCDOT) in 2000. 

A conversion of $4 million/mile was applied to the interstate expenditures. For expenditures on 

other arterial and collectors, a conversion factor of $1.9 million/mile was applied, which 

corresponds to all other projects. 

The new miles of road constructed are used to estimate the acreage disturbed due to road 

construction. The total area disturbed in each state was calculated by converting the new miles 

of road constructed to acres using an acres disturbed/mile conversion factor for each road type as 

given in Table 2 below: 

Table 2: Spending per Mile and Acres Disturbed per Mile by Highway Type

Rural Areas, Other Arterials 1900 12.7

Urban Areas, Collectors 1900 9.8

Rural Areas, Collectors 1900 7.9

Residential building starts are used to allocate the state-level acres disturbed by road construction 

to the county.3 A ratio of the number of building starts in each county to the total number of 

building starts in each state was applied to the state-level acres disturbed to estimate the total 

number of acres disturbed by road construction in each county. 

Converting Acres Disturbed to Tons of Land Clearing Debris Burned 

Version 2 of the Biogenic Emissions Land cover Database (BELD2) within EPA’s Biogenic 

Emission Inventory System (BEIS) was used to identify the acres of hardwoods, softwoods, and 

grasses in each county. Table 3 presents the average fuel loading factors by vegetation type. 

The average loading factors for slash hardwood and slash softwood were adjusted by a factor of 

1.5 to account for the mass of tree that is below the soil surface that would be subject to burning 

once the land is cleared.8

 Weighted average county-level loading factors were calculated by 

multiplying the average loading factors by the percent contribution of each type of vegetation 

class to the total land area for each county. 
Page 153

Hardwood 66 99 

Softwood 38 57 

Grass 4.5 Not Applicable 

The total acres disturbed by all construction types was calculated by summing the acres disturbed 

from residential, non-residential, and road construction. The county-level total acres disturbed 

were then multiplied by the weighted average loading factor to derive tons of land clearing 

debris in 2008. 

c. Controls 

Controls for land clearing debris burning are generally in the form of a ban on open burning of 

waste in a given municipality or county. Counties that were more than 80% urban were assumed 

not to practice any open burning. Therefore, criteria pollutant and HAP emissions from open 

burning of land clearing debris are zero in these counties. In addition, the State of Colorado 

implemented a state-wide ban on open burning. Emissions from open burning of land clearing 

debris in all Colorado counties were assumed to be zero. 

d. Emission Factors 

Emission factors are reported in Table 4 below. Emission factors for CAPs were developed by 

the U.S. Environmental Protection Agency (EPA) in consultation with the Eastern Regional 

Technical Advisory Committee and based primarily on the AP-42 report.9,10 Emission factors for 

HAPs are from an EPA Control Technology Center report and emission factors for 17 dioxin 

congeners were obtained from an EPA dioxin report.11,12 The Dioxin emission factors were 

multiplied by 0.002 to convert from mg/kg to lb/ton. 

e. Emissions 

County-level criteria pollutant and HAP emissions (in lb/year) were calculated by multiplying 

the total mass of land clearing debris burned per year by an emission factor. 

f. Example Calculations 

VOC emissions in Autauga County, Alabama from open burning of land clearing debris: 

Rural fraction of Autauga County population = 0.448, so no emission controls 

Acres disturbed by residential, non-residential, and road construction in Autauga County = 434.26 

Weighted average fuel loading factor for Autauga County = 65.48 tons/acre 

Mass of land clearing debris burned = 434.26 acres * 65.48 tons/acre = 28,437 tons 
Page 154 

VOC emission factor = 11.6 lbs/ton 

Factor to convert from lbs to tons = 1/2000 

VOC emissions = tons of land clearing debris burned * VOC emission factor 

VOC emissions from land clearing debris burning = 28,437 tons * 11.6 lbs/ton * 1 ton/2000 lbs 

VOC emissions from land clearing debris burning in Autauga County in 2008 = 165 tons

3.2.3.18 Open Burning – Residential Household Waste 

a. Source Category Description 

Open burning of residential municipal solid waste (MSW) is the purposeful burning of MSW in 

outdoor areas. Criteria air pollutant (CAP) and hazardous air pollutant (HAP) emission estimates 

for MSW burning are a function of the amount of waste burned per year. 

For this source category, the following SCC was assigned: 

SCC SCC Level 1 SCC Level 2 SCC Level 3 SCC Level 4 

2610030000 Waste Disposal, 

Treatment, and Recovery 

Open Burning Residential Household Waste 

(use 26-10-000-xxx 

for Yard Wastes) 

b. Activity Data 

The amount of household MSW burned was estimated using data from EPA’s report Municipal 

Solid Waste in the United States: 2007 Facts and Figures.

1

 The report presents the total mass of 

waste generated in the United States by type of waste for the calendar year 2007. This 

information was used to calculate a daily estimate of the per capita household waste subject to 

burning, 3.40 lbs/person/day. Non-combustible waste, such as glass and metals, was not 

considered to be waste subject to burning. Burning of yard waste is included in SCC 

2610000100 and SCC 2610000400; therefore, it is not part of residential MSW. Approximately 

25 to 32 percent of all waste that is subject to open burning is actually burned.2 A median value 

of 28 percent is assumed to be burned in all counties in the United States. 

Since open burning is generally not practiced in urban areas, only the rural population of each 

county was assumed to practice open burning. The ratio of urban to rural population was 

obtained from 2000 U.S. Census data.3 This ratio was then multiplied by the 2008 U.S. Census 

Bureau estimate of the population in each county to obtain the county-level rural population for 

2008.4 The county-level rural population was then multiplied by the per capita household waste 

subject to burning to determine the amount of rural household MSW generated in each county in 

2008. 

c. Controls 

Controls for residential MSW burning are generally in the form of a ban on open burning of 

waste in a given municipality or county. Counties that were more than 80% urban were assumed 

not to practice any open burning. Therefore, criteria pollutant and HAP emissions from 

residential municipal solid waste burning are zero in these counties. In addition, the State of 

Colorado implemented a state-wide ban on open burning. Emissions from open burning of 

residential waste in all Colorado counties were assumed to be zero. 

d. Emission Factors 

Emission factors are reported in Table 1 below. Emission factors for CAPs were developed by 

the U.S. Environmental Protection Agency (EPA) in consultation with the Eastern Regional 

Technical Advisory Committee and based primarily on the AP-42 report.5,6 Emission factors for 
Page 157 

HAPs are from an EPA Control Technology Center report and emission factors for 17 dioxin 

congeners were obtained from an EPA dioxin report.7,8

e. Emissions 

County-level criteria pollutant and HAP emissions were calculated by multiplying the total 

amount of residential municipal solid waste burned per year by an emission factor. 

 

f. Example Calculations 

VOC emissions in Autauga County, Alabama from open burning of residential MSW: 

Population of Autauga County in 2008 = 50,364 

Rural fraction of Autauga County population = 0.448 

Per capita MSW waste generated (lb/person/day) = 3.40 

Fraction of rural population that burns MSW = 0.28 

Number of days in a year = 365 

Factor to convert from lbs to tons = 1/2000 

2008 MSW burning activity in Autauga County = 50,364 * 0.448 * 3.40 * 0.28 * 365 * 1/2000 

2008 leaf burning activity in Autauga County = 3,921 tons 

VOC emissions = tons of leaves burned * VOC emission factor 

VOC emission factor = 8.56 lb/ton 

VOC emissions from leaf burning in Autauga County in 2008 = 3,921 tons * 8.56 lbs/ton * 1 ton/2000 lbs 

VOC emissions from leaf burning in Autauga County in 2008 = 16.78 tons

Municipal Solid Waste in the United States: 2007 Facts and Figures.1 The report presents the 

total mass of waste generated in the United States by type of waste, including yard waste, for the 

calendar year 2007. This information was used to calculate a daily estimate of the per capita 

yard waste, 0.59 lbs/person/day. Of the total amount of yard waste generated, the yard waste 

composition was assumed to be 25 percent leaves, 25 percent brush, and 50 percent grass by 

weight.2

 

Open burning of grass clippings is not typically practiced by homeowners, and as such only 

estimates for leaf burning and brush burning were developed. Approximately 25 to 32 percent of 

all waste that is subject to open burning is actually burned.2 A median value of 28 percent is 

assumed to be burned in all counties in the United States. 

The per capita estimate was then multiplied by the 2008 population in each county that is 

expected to burn waste. Since open burning is generally not practiced in urban areas, only the 

rural population of each county was assumed to practice open burning. The ratio of urban to 

rural population was obtained from 2000 U.S. Census data.3

 This ratio was then multiplied by 

the 2008 U.S. Census Bureau estimate of the population in each county to obtain the countylevel rural population for 2008.4

The percentage of forested acres from Version 2 of BELD2 within BEIS was used to adjust for 

variations in vegetation. The percentage of forested acres per county (including rural forest and 

urban forest) was then determined. To better account for the native vegetation that would likely 

be occurring in the residential yards of farming States, agricultural land acreage was subtracted 

before calculating the percentage of forested acres. Table 1 presents the ranges that were used to 

make adjustments to the amount of yard waste that is assumed to be generated per county. All 

municipios in Puerto Rico and counties in the U.S. Virgin Islands, Hawaii, and Alaska were 

assumed to have greater than 50 percent forested acres.

per County Yard Waste Generated

< 10% 0% generated 

>= 10%, and < 50% 50% generated 

>= 50% 100% generated 

c. Controls 

Controls for yard waste burning are generally in the form of a ban on open burning of waste in a 

given municipality or county. Counties that were more than 80% urban were assumed not to 

practice any open burning. Therefore, criteria pollutant and HAP emissions from residential 

municipal solid waste burning are zero in these counties. In addition, the State of Colorado 

implemented a state-wide ban on open burning. Emissions from open burning of residential 

waste in all Colorado counties were assumed to be zero. 

d. Emission Factors 

Emission factors are specific to yard waste type and are reported in Tables 2 and 3 below. 

Emission factors for CAPs were developed by the U.S. Environmental Protection Agency (EPA) 

in consultation with the Eastern Regional Technical Advisory Committee.5 Emission factors for 

HAPs are from AP-42 and an EPA Control Technology Center report.6,7 Forest fire simulation 

emission factors were used to estimate emissions for 17 dioxin congeners.8

e. Emissions 

County-level criteria pollutant and HAP emissions were calculated by multiplying the total 

amount of yard waste (either leaf or brush) burned per year by an emission factor. Emissions for 

leaves and residential brush were calculated separately, since emission factors vary by yard 

waste type. Tons of debris burned were converted to kilograms (kg) by multiplying by 

907.18474. 

f. Example Calculations 

VOC emissions in Autauga County, Alabama from open burning of leaf waste: 

Population of Autauga County in 2008 = 50,364 

Rural fraction of Autauga County population = 0.448 

Per capita waste yard waste generated (lb/person/day) = 0.59 

Leaf fraction of waste = 0.25 

Fraction of rural population that burns yard waste = 0.28 

Adjustment factor based on % forested acres = 1 

Number of days in a year = 365 

Factor to convert from lbs to tons = 1/2000 

2008 leaf burning activity in Autauga County = 50,364 * 0.448 * 0.59 * 0.25 * 0.28 * 1 * 365 * 1/2000 

2008 leaf burning activity in Autauga County = 170.11 tons 

VOC emissions = tons of leaves burned * VOC emission factor 
Page 163 

VOC emission factor = 28 lb/ton 

VOC emissions from leaf burning in Autauga County in 2008 = 170.11 tons * 28 lbs/ton * 1 ton/2000 lbs 

VOC emissions from leaf burning in Autauga County in 2008 = 2.38 tons

3.2.3.20 Agricultural Production – Crops – Fertilizer 

a. Source Category Description 

Fertilizer in this category refers to any nitrogen-based compound, or mixture containing such a 

compound, that is applied to land to improve plant fitness. 

The approach to calculating emissions for the assigned SCCs consisted of three general steps, as 

follows: 

 Calculating the percent change in county-level fertilizer quantities applied 

between 2002 and 2007. 

 Using the percent change in applied fertilizer quantity to grow the fertilizer 

activity files provided with the CMU Ammonia Model v.3.6.1

 Running the CMU Ammonia Model to calculate ammonia emissions based on the 

updated county-level fertilizer quantities. 

For this source category, the following SCCs were assigned:

b. Activity Data 

County-level fertilizer consumption data for 2002 and 2007 was obtained from the Fertilizer 

Institute’s Commercial Fertilizers 2002 and 2007 reports.2 The consumption data includes total 

fertilizer sales or shipments for farm and non-farm use and is reported semi-annually for the 

fiscal year. To make the fertilizer types listed in the Commercial Fertilizers reports match the 

activity input files from the CMU Ammonia Model, the fertilizer types were grouped according 

to Table 1 below. For any state in 2002 reporting fertilizer quantities from unknown counties, the 

quantities were apportioned to every county in the state based on cropland area obtained from the 

U.S. Department of Agriculture’s 2002 Census of Agriculture.3

 Similarly for 2007, fertilizer 

quantities from unknown counties were apportioned based on cropland area reported in the 2007 

Census of Agriculture.4

 For each fertilizer group, the percent difference in fertilizer consumption 

between 2002 and 2007 was calculated for each county. These percentages were used to grow 

the 2002 county-level nitrogen quantities from the fertilizer activity files provided with the CMU 

Ammonia Model v.3.6. 

The average nitrogen content for each fertilizer group, reported in Table 2, was calculated by 

summing the county-level fertilizer quantities for all counties from the CMU Ammonia Model 

activity files to generate total nitrogen applied. For each fertilizer group, the total nitrogen 

applied was then divided by the 2002 fertilizer consumption data from the 2002 Commercial 

Fertilizers report to obtain the percent nitrogen content for each fertilizer group. For any county 

with fertilizer consumption in 2007, but not in 2002, the fertilizer quantity obtained from the 

2007 Commercial Fertilizer’s report was multiplied by the percent nitrogen content of each 

fertilizer group to determine tons of nitrogen. The tons of nitrogen were then converted to 

kilograms and allocated temporally by month according to the state-level percentage of total 
Page 168 

fertilizer in that group applied each month. The state-level percentage was calculated using data 

in the CMU Ammonia Model input files. 

c. Emission Factors 

Emission factors for each fertilizer group were provided with the CMU Ammonia Model and are 

reported in Table 3 below.3

 

d. Emissions 

The fertilizer activity files provided with the CMU Ammonia Model v.3.6 were replaced with the 

updated county-level fertilizer files. County-level ammonia emissions were then calculated by 

running the model. The model corrects for the difference in mass between nitrogen and 

ammonia. 

 N applied x % N volatilized as NH3 x 17 g /14 g = NH3 emissions 

e. Sample Calculations 

Allocation of Fertilizer Quantities from Unknown Counties 

From the 2007 Commercial Fertilizers report, Colorado reported 4,774,000 kg of 

ammonium nitrate from unknown counties for January through June of 2007. This quantity was 

distributed to counties based on the percent of cropland in the state located in each county. For 

example, Colorado has 11,484,000 acres of cropland. Adams County, Colorado has 547,000 

acres of cropland. 

Percent of cropland in CO located in Adams County = (547,000 / 11,484,000) x 100 = 

4.76 

Ammonium nitrate allocated to Adams County = 4,774,000 kg x .0476 = 227,240 kg 

Growing the CMU Ammonia Model Input Files 

After allocating fertilizer data from unknown counties for 2002 and 2007, the countylevel percent difference between fertilizer quantity applied in 2002 and 2007 was used to grow 

the data in the activity files provided with the CMU Ammonia Model. For example, Autauga 

County, Alabama applied 473,180 kg of ammonium nitrate from July 2001 through December 

2001 and 516,240 kg from July 2006 through December 2006. 

Percent change in ammonium nitrate applied = (516,240 kg / 473,180 kg) x 100 = 109 
Page 169 

The quantity of nitrogen, in the form of ammonium nitrate, applied per month from July 

through December 2002 in Autauga County was extracted from the CMU Ammonia Model 

activity files and multiplied by the percent change. 

July: 3,250 kg x 1.09 = 3,543 kg N 

August: 3,210 kg x 1.09 = 3,499 kg N 

September: 9,640 kg x 1.09 = 10,508 kg N 

October: 6,320 kg x 1.09 = 6,889 kg N 

November: 2,600 kg x 1.09 = 2,834 kg N 

December: 1,380 kg x 1.09 = 1,504 kg N 

Calculation of Nitrogen Content in a Fertilizer Group 

The sum of all nitrogen applied in the form of ammonium nitrate from the CMU 

Ammonia Model ammonium nitrate activity file was 508,000,000 kg. From the 2002 

Commercial Fertilizers report, the total quantity of ammonium nitrate applied in 2002 was 

1,420,000,000 kg. 

N content of ammonium nitrate = (508,000,000 kg / 1,420,000,000 kg) x 100 = 36 % 

County Where Fertilizer was Applied in 2007, but not in 2002 

 In Meade County, Kentucky, there was no ammonium nitrate applied from January to 

June of 2002, but there were 356,705 kg applied from January to June of 2007. To convert to kg 

of nitrogen, the quantity of ammonium nitrate applied in 2007 was multiplied by the nitrogen 

content of ammonium nitrate. 

 N applied = 356,705 kg x 0.36 = 128,414 kg 

The quantity of nitrogen was then allocated temporally by month from January to June based on 

the state-level distribution of nitrogen applied in the form of ammonium nitrate from the CMU 

Ammonia Model ammonium nitrate activity file. Total nitrogen in the form of ammonium nitrate 

applied in Kentucky from January through June of 2002 was 17,000,000 kg. The total for 

January was 289,000 kg. The total for February was 745,000 kg. 

January: (289,000 kg / 17,000,000 kg) x 128,414 kg = 2,183 kg N applied in Meade 

County 
Page 170 

February: (745,000 kg / 17,000,000 kg) x 128,414 kg = 5,600 kg N applied in Meade 

County 

March – June: calculated same as above.

3.2.3.21 Publicly Owned Treatment Works 

a. Source Category Description 

Publicly Owned Treatment Works (POTW) means a treatment works that is owned by a state, 

municipality, city, town, special sewer district, or other publicly owned and financed entity as 

opposed to a privately (industrial) owned treatment facility. The definition includes intercepting 

sewers, outfall sewers, sewage collection systems, pumping, power, and other equipment. The 

wastewater treated by these POTWs is generated by industrial, commercial, and domestic 

sources.1

 

The general approach to calculating emissions for POTWs is to estimate the 2008 national 

POTW flow rate using methods described below and then multiply the estimated flow rate by the 

emission factors for VOCs, ammonia, and 53 HAPs. The emissions are allocated to the county 

level using methods described below. 

b. Activity Data 

A nationwide projected flow rate in 2010 of 39,780 million gallons per day (MMGD) was 

available from an EPA report.2 Of this, POTWs account for 98.5 percent of the flow rate or 

39,180 MMGD, with privately owned treatment works accounting for the rest. The EPA Clean 

Watersheds Needs Survey reports the existing flow rate in 2004 for POTWs as 34,370 MMGD.3

 

The interpolated 2008 nationwide flow rate (using a linear regression) was calculated at 37,580 

MMGD, or 13,754,280 million gallons annually. The nationwide flow rate includes Puerto Rico 

and the U.S. Virgin Islands. 

c. Emission Factors 

The ammonia emission factor was obtained from a report to EPA4, while the VOC emission 

factor was based on a TriTAC study.5

 Emission factors for the 53 HAPs were derived using 1996 

area source emissions estimates that were provided by ESD6 and the 1996 nationwide flow rate.7

These HAP emission factors were then multiplied by the 2008 to 2002 VOC emission factor 

ratio (0.85/9.9) to obtain the final HAP emission factors applied in the 2008 inventory. The 

emission factors, pollutant codes, and pollutant descriptions are reported in Table 1. 

d. Emissions 

Emissions were allocated to the county-level by the county proportion of the U.S. population.8

 

It is important to note that the emission estimates for this category represent total emissions. It 

may be necessary to determine whether there are point source emissions in SCCs 50100701 

through 50100781 and 50100791 through 50182599 that need to be subtracted to yield the 

nonpoint source emission estimates for this category. 

Though there are two point source facilities in Missouri that are POTW’s, their emissions were 

not subtracted from the area source category due to time constraints and small level of emissions 

compared to the area source category. 
Page 175 

e. Sample Calculations: 

The 1996 flow rate per day was 32,175 MMGD. (1996 was a leap year.) Annually, this 

computes to: 

32,175 MMGD treated * 366 days = 11,776,050 million gallons treated 

Benzene emissions in 1996 for area source POTWs were estimated to be 461.44 tons per year. 

The derived benzene emission factor is calculated as follows: 

Benzene emission factor = ((461.44 tons * 2000 lb/ton) / (11,776,050 million gallons 

treated)) * (0.85/9.9) 

Benzene emission factor = 0.0067287 lb/million gallons treated 

Benzene emissions for 2008 for area source POTWs are calculated as follows: 

2008 Benzene emissions = (37,580 MMGD * 366 days) * (0.0067287 lb/million gallons 

treated) 

2008 Benzene emissions = 92,548 pounds / 2,000 pounds = 46.27 tons/year 

Total national 2008 benzene emissions from area source POTWs are allocated to county-level by 

the county proportion of the U.S. population. The total U.S. population in 2008 is 308,123,578. 

Benzene emissions for Autauga County, Alabama (2008 population of 50,364) are calculated as 

follows: 

 2008 emissions = 46.27 tons/year * 50,364/308,123,578 = 0.0076 tons/year

3.2.3.22 Solvent Utilization 

a. Source Category Description

Solvent Utilization describes a wide range of activities where the primary pollutants released are 

volatile organic compounds (VOCs). Some examples would be surface coating operations 

(where a paint or finish is applied to a manufactured product), or consumer and commercial 

cleaning product application. The list of SCCs is included in Table 1. 

b. Activity Data 

The three types of activity data collected are population, road miles (used for traffic markings), 

and employment data. Table 1 shows the type of activity data used for each category and 

provides the SCC. Employment data is listed by the North American Industrial Classification 

Standard (NAICS) code(s) that were used to determine county-level employment for the 

category. 

Population data was collected from the U.S. Census Bureau’s population estimates for July 1, 

2008. 

For traffic paints, the Federal Highway Administration provides county-level road miles as a part 

of their HPMS data. The most recent data set available at the time of compilation was 2006. 

Employment data was allocated to each county using County Business Patterns (CBP) 

employment data for 2006 (the most recent data available at the time of compilation). One of the 

limitations of County Business Patterns is the fact that data can be withheld if certain conditions 

are present so that confidential business data is not revealed. Divita 2009 describes how this 

limitation is overcome by applying a procedure to estimate the number of employees in a 

withheld county. For SCCs with multiple NAICS associated with them, this allocation procedure 

is performed for each individual NAICS. 

Point source subtraction is completed by determining the number of employees per county in 

each of the associated NAICS codes and subtracting them from the CBP county total prior to 

calculating emissions. Table 2 lists the solvent categories and their point source subtraction 

results. In some cases, the entire county area source emission estimate becomes zero because all 

of the CBP employees are accounted for in the point source category. 

c. Control Factors 

For several categories, air pollution regulations exist that regulate the solvent content of products 

which can be sold. These solvent content limits have been taken into account where appropriate 

by modifying emission factors rather than developing control efficiency information. 
Page 180 

d. Emission Factors 

Emission factors were developed and reviewed by an ERTAC advisory panel composed of state 

and EPA personnel. Table 3 lists the SCC, pollutant, and emission factors that were developed 

for categories with the same factor throughout the country. As mentioned in the control factors 

section above, there were several categories where the emission factor was adjusted to account 

for rules that limit solvent content. Table 4 lists the categories with their uncontrolled and 

controlled emission factors while Table 5 lists the states for which controlled emission factors 

were applied. 

e. Sample Calculations 

Emissions are calculated for each county using emission factors and activity as: 

 Ex,p = Ax × EFx,p

where: 

 Ex,p = annual emissions for category x and pollutant p 

 Ax = Population or employment data associated with category x 

 EFx,p = emission factor for category x and pollutant p 

Example: 

Using architectural coatings in Allegheny County, PA as an example: 

According to the U.S. Census Bureau, population on July 1, 2008 is 1,215,103 

The emission factor for VOC is 2.41 lb/person 

 EVOC = 1,215,103 people × 2.41 lb VOC/ person

 = 2,928,398 lb VOC or 1,464.2 ton VOC

3.2.3.23 Gasoline Distribution Stage I 

a. Source Category Description 

Stage I gasoline distribution includes the following gasoline emission points: 1) bulk terminals; 

2) pipeline facilities; 3) bulk plants; 4) tank trucks; and 5) service stations. Emissions from 

Stage I gasoline distribution occur as gasoline vapors are released into the atmosphere. These 

Stage I processes are subject to EPA’s maximum available control technology (MACT) 

standards for gasoline distribution.1 

Emissions from gasoline distribution at bulk terminals and bulk plants take place when gasoline 

is loaded into a storage tank or tank truck, from working losses (for fixed roof tanks), and from 

working losses and roof seals (for floating roof tanks). Working losses consist of both breathing 

and emptying losses. Breathing losses are the expulsion of vapor from a tank vapor space that 

has expanded or contracted because of daily changes in temperature and barometric pressure; 

these emissions occur in the absence of any liquid level change in the tank. Emptying losses 

occur when the air that is drawn into the tank during liquid removal saturates with hydrocarbon 

vapor and expands, thus exceeding the fixed capacity of the vapor space and overflowing 

through the pressure vacuum valve.2

Emissions from tank trucks in transit occur when gasoline vapor evaporates from (1) loaded tank 

trucks during transportation of gasoline from bulk terminals/plants to service stations, and (2) 

empty tank trucks returning from service stations to bulk terminals/plants.3 Pipeline emissions 

result from the valves and pumps found at pipeline pumping stations and from the valves, 

pumps, and storage tanks at pipeline breakout stations. Stage I gasoline distribution emissions 

also occur when gasoline vapors are displaced from storage tanks during unloading of gasoline 

from tank trucks at service stations (Gasoline Service Station Unloading) and from gasoline 

vapors evaporating from service station storage tanks and from the lines going to the pumps 

(Underground Storage Tank Breathing and Emptying).

b. Bulk Terminals and Pipelines 

There are no generally accepted activity-based VOC emission factors for the pipelines and bulk 

terminals sectors because they are generally treated as point sources whose emissions are 

estimated using site-specific information. For example, emission estimates for bulk terminal 

storage tanks are typically derived from tank specific parameters that are input into the TANKS 

program.

4

 Therefore, for bulk terminals and pipelines, EPA estimated 2008 national VOC 

emissions by multiplying 1998 national estimates developed in support of the Gasoline 

Distribution MACT standard5

 by the 2008 to 1998 ratio of the national volume of wholesale 

gasoline supplied (see Table 1). The gasoline supply information was obtained from Table 2 in 

Volume I of Petroleum Supply Annual 2008.6

To estimate HAP emissions, EPA applied national average speciation profiles to the VOC 

emission estimates.7

 Table 2 presents these speciation profiles and the national bulk terminal 

and pipeline HAP emission estimates (note that unless otherwise noted, all emission values 

reported in this section exclude estimates for Puerto Rico and the U.S. Virgin Islands). EPA used 

total VOC emission estimates, so emissions represent total emissions. Where necessary, States 

should perform point source subtractions to obtain nonpoint emissions. The following describes 

how total national VOC estimates were allocated to counties.

For both categories, EPA allocated national VOC and HAP emissions for these categories in a 

two-step manner. First, EPA allocated emissions based on 2008 gasoline supply data reported by 

the U.S. Department of Energy (DOE). Next, EPA allocated emissions based on employment 

data reported in the 2007 County Business Patterns.8

For pipelines, EPA allocated emissions to Petroleum Administration for Defense (PAD) Districts 

based on the total amount of finished motor gasoline moved by pipeline in each PAD in year 

2008. There are five PAD Districts across the United States: PAD District 1 comprises 

seventeen states plus the District of Columbia along the Atlantic Coast; PAD District 2 

comprises fifteen states in the Midwest; PAD District 3 comprises six states in South Central 

U.S.; PAD District 4 comprises five states in the Rocky Mountains; and PAD District 5 

comprises seven states along the West Coast. These data, which are displayed below in Table 3, 

are reported in Table 35 of Volume 1 of Petroleum Supply Annual 2008.9 Next, EPA allocated 

pipeline emissions in each PAD District to counties based on County Business Patterns 

employment data. Because employment data for NAICS code 48691 (Pipeline Transportation of 

Refined Petroleum Products) are often withheld due to confidentiality reasons, EPA used the 

number of employees in NAICS code 42471 (Petroleum Bulk Stations and Terminals) for this 

allocation. To better account for the location of refined petroleum pipelines, however, EPA did 

not allocate any activity to States which had employees in this NAICS code, but did not have 

employees in NAICS code 48691 (i.e., District of Columbia, Idaho, Maine, New Hampshire, 

Vermont, and West Virginia).

For bulk terminals, EPA first allocated national emissions to States based on the 2008 refinery, 

bulk terminal, and natural gas plant stocks of motor gasoline reported for each State in Table 33 

of Volume 1 of DOE’s Petroleum Supply Annual 2008 (see Table 4).9

 Next, EPA allocated 

emissions in each State to counties based on the number of NAICS code 42471 (Petroleum Bulk 

Stations and Terminals) employees reported in the 2007 County Business Patterns.8

It is important to reiterate that the above discussion addresses the calculation of total VOC 

emissions. The 2008 point source NEI reports VOC emissions related to bulk terminal and 

pipeline processes. To obtain nonpoint emissions, States should subtract the 2008 point source 

VOC emission estimates from the total VOC emission estimates reported here. The relevant 

point source SCCs are listed in Tables 5 and 6 below.

c. Bulk Plants 

EPA calculated VOC emissions from bulk plants by developing an average emission factor from 

the bulk plant motor gasoline VOC emissions and throughput data developed in support of the 

Gasoline Distribution MACT standards.2,5 To estimate 2008 national VOC emissions, the VOC 

emission factor (8.62 pounds of VOC per 1,000 gallons) was applied to the estimated national 

volume of gasoline passing through bulk plants in 2008. The volume of bulk plant gasoline 

throughput was assumed to be 9 percent of total gasoline consumption.10 Total gasoline 

consumption for 2008 was assumed to be the same as the volume of finished motor gasoline 

supplied as reported on the U.S. Energy Information Administration’s Petroleum Navigator 

website.11 The resulting national VOC emission estimate was then allocated to counties based on 

employment data for NAICS code 42471 (Petroleum Bulk Stations and Terminals). To estimate 

benzene emissions from bulk plants, EPA multiplied VOC emission estimates by county-level 

speciation profiles calculated from the annual onroad refueling (Stage 2) emissions from the 

2008 NEI NMIM results.12 All other HAPs were estimated by multiplying VOC emissions by the 

national average speciation profiles displayed in Table 7.

nonpoint emissions, States should subtract the 2008 point source VOC emission estimates from

d. Tank Trucks in Transit 

The EPA calculated VOC emissions from Tank Trucks in Transit by multiplying county-level 

tank truck gasoline throughput by a 0.06 lb of VOC per 1,000 gallon emission factor. As noted 

in Table 9, this emission factor is the sum of the individual emission factors reported in the 

Gasoline Distribution EIIP guidance document for gasoline-filled trucks (traveling to service 
Page 206 

station/bulk plant for delivery) and vapor-filled trucks (traveling to bulk terminal/plant for 

reloading).3

 County-level gasoline consumption was estimated by summing county-level onroad 

and nonroad estimates. County-level onroad consumption was estimated by subtracting the 

NMIM-derived national nonroad consumption from the EIA’s estimate of finished motor 

gasoline supplied and then allocating to counties using NMIM-derived onroad county-level CO2

emissions.11,13 County-level nonroad consumption was estimated by allocating NMIM-derived 

state/SCC-level nonroad gasoline consumption to the county-level based on nonroad 

county/SCC-level CO2 emissions.13 Gasoline throughput for tank trucks was computed by 

multiplying the county-level gasoline consumption estimates by a factor of 1.09 to account for 

gasoline that is transported more than once in a given area (i.e., transported from bulk terminal to 

bulk plant and then from bulk plant to service station).10 Benzene emission estimates were 

calculated by multiplying county-level NMIM speciation profiles by the VOC emission 

estimates.12 Emissions for the remaining HAPs were calculated by multiplying VOC emissions 

by the national speciation profiles presented in Table 10.

obtain nonpoint emissions, States should subtract the 2008 point source VOC emission estimates 

from the total VOC emission estimates reported here. The relevant point source SCCs are listed 

in Table 11 below.

e. Underground Storage Tank (UST) Breathing and Emptying 

The EPA calculated VOC emissions from UST breathing and emptying by multiplying countylevel total gasoline consumption, calculated as described above in the Tank Trucks in Transit 

section, by the 1 lb/1,000 gallons emission factor recommended by the Gasoline Distribution 

EIIP guidance document.3 With the exception of benzene, HAP emissions were estimated by 

multiplying VOC emissions by the national HAP speciation profiles listed in Table 12. To 

estimate benzene emissions, EPA multiplied VOC emissions by county-level speciation profiles 

from NMIM.12

f. Gasoline Service Station Unloading 

The EPA estimated uncontrolled VOC emissions from unloading of gasoline into service 

station tanks from county-level total gasoline consumption estimates, calculated as 

described above in the Tank Trucks in Transit section, and the following AP-42 equation: 

L = (12.46 x S x P x M)/T 

where: 

L = uncontrolled loading loss of liquid loaded (in lb/1,000 gallons) 

S = saturation factor; 

P = true vapor pressure of liquid loaded (pounds per square inch absolute); 

M = molecular weight of vapors (lbs per lb/mole); and 

T = temperature of liquid loaded (Rankine).14
Page 209 

This equation requires geographic-specific information. This information includes the 

saturation factor, which differs by method of loading (e.g., submerged filling), Reid 

vapor pressure (RVP), temperature, and true vapor pressure of gasoline. 

Gasoline RVP values were obtained from the NMIM 2008 database. Because NMIM is a 

county-level database that reports RVP values by month, EPA developed county-level 

monthly gasoline consumption estimates by multiplying annual county gasoline 

consumption by monthly allocation factors. State-level monthly allocation factors were 

developed from monthly gasoline sales data reported in the Federal Highway 

Administration's Highway Statistics 2008.15 Geographic-specific information on the 

temperature of gasoline and the method of loading were obtained from a Stage I and II 

gasoline emission inventory study prepared for the EIIP.16 

The true vapor pressure of gasoline was estimated for each county/month using the 

following equation: 

where: 

P = Stock true vapor pressure, in pounds per square inch absolute. 

T = Stock temperature, in degrees Fahrenheit. 

RVP = Reid vapor pressure, in pounds per square inch. 

S = Slope of the ASTM distillation curve at 10 percent evaporated, in degrees 

Fahrenheit per percent (assumed that S = 3.0 for gasoline per Figure 7.1-14a 

of AP-42).17

This equation was used to calculate monthly county-level true vapor pressure estimates. 

In cases where more than one filling method was assumed to apply in a county (e.g., due 

to vapor balancing requirement applying to a portion of a county’s total gasoline 

throughput due to a throughput exemption), EPA developed two sets of calculations for 

each month, one for each filling method. 

The EIIP study regional stock temperature information was used to estimate the 

temperature of gasoline in each county in each month (see Table 14).16

The EPA incorporated the effect of Stage I Gasoline Service Station vapor balancing 

controls based on the county-level control efficiency values (either 90 or 95 percent) that 

were compiled for the EIIP study.16 Table 15 presents the HAP speciation profiles and 

total VOC and HAP emission estimates calculated using these procedures. 

Emissions are reported by SCC based on the filling methods used in each county as 

determined from the EIIP study: SCC 2501060051 (Submerged Filling); SCC 

2501060052 (Splash Filling); and SCC 2501060053 (Balanced Submerged Filling).

3.2.3.24 Gasoline Distribution – Stage II 

a. Source Category Description 

Stage II gasoline distribution emissions are the refueling emissions that occur during the 

transfer of gasoline from storage tanks at service stations to vehicle fuel tanks. 

Stage II emissions are reported under the following nonpoint SCC: 

SCC SCC Level 1 SCC Level 2 SCC Level 3 SCC Level 4 

2501060100 Storage and Transport Petroleum and 

Petroleum Product 

Storage 

Gasoline Service 

Stations 

Stage 2: Total 

This SCC is only used in the NEI to report emissions for on-road gasoline vehicle 

refueling. (Estimates for Stage II nonroad equipment gasoline refueling are included in 

the nonroad source inventory.) 

b. Emissions Calculations 

The VOC emission estimates for Stage II gasoline distribution in 2008 were generated 

via MOVES 2010a. The refueling vapor-loss and refueling spillage emission categories 

are defined in MOVES 2010a as emission processes 18 and 19. The MOVES runs 

performed as discussed in the on-road mobile source emission calculation section of this 

document included these two emission processes, but the emissions from these two 

emission processes were separated from the on-road mobile source emissions during the 

post-model emissions analysis. The 2008 average ozone season day Stage II gasoline 

distribution emissions for both vapor loss and spillage for each county in the Missouri 

portion of the St. Louis Ozone nonattainment area, as calculated with MOVES 2010a, are 

reported in Table 1 below. 

MOVES 2010a includes a default table for each county in the country called 

“countyyear”. The “countyyear” table establishes values for the stage II control 

efficiencies in each county. The MOVES default control efficiencies for Stage II vapor 

loss and Stage II spillage emissions in the St. Louis Ozone nonattainment area are 95% 

and 50%, respectively. These default values were used when running the MOVES model 

for 2008.

3.2.3.25 Fuel Combustion – Industrial and Commercial/Institutional (ICI) 

The Central States Regional Planning Association (CENRAP) contracted with Pechan to 

provide an updated methodology to calculate ICI fuel combustion emissions for 2002, 

and make the methodology updatable for future inventory projects. Appendix C-6 is 

documentation of the ICI methodology and describes how it is applied to a revised 2002 

inventory. 

Statewide emissions are calculated using the fuel activity and emission factors, then 

statewide point source emission contributions are subtracted, and finally the emissions 

are allocated to counties. The Energy Information Administration’s (EIA’s) State Energy 

Data System (SEDS) provides total energy consumption by sector, but the values have to 

be adjusted by energy not used for combustion and nonroad equipment use. EIA’s 2002 

Manufacturing Energy Consumption Survey (MECS) was used to get regional sectoral 

energy consumption that is not used for combustion. A run of the NONROAD model for 

2006 provided the diesel and LPG quantity to subtract for commercial sector nonroad 

equipment. Emission factors from Roy Huntley of the EPA, the Emission Inventory 

improvement Plan (EIIP), and AP-42 cover the various fuel types for criteria pollutants. 

Emissions from coal combustion require the use of Missouri-specific coal sulfur content 

from the Energy Information Administration Quarterly Coal Report. Statewide point 

source emission contributions are subtracted by compiling the sector’s CO emissions by 

Source Classification Code (SCC), which is fuel specific, back-calculating using AP-42 

emission factors to a fuel throughput, and subtracting that fuel throughput from the 

statewide total. Before allocating the remaining nonpoint emissions to Missouri counties, 

an energy-intensity adjustment is done to account for the variation of energy used per 

employee for each industrial manufacturing NAICS code. County Business Patterns

(CBP) published annually by the US Census Bureau outlines employment by NAICS 

codes and the energy-intensity per employee by NAICS code derived from EIA’s 2002 

Annual Energy Outlook. Emissions are then allocated to individual counties based on 

commercial/institutional employment by county and based on energy intensity and 

employment for the industrial sector. 

Appendix C-6 outlines the activity data used, emission factors, and the calculation 

template spreadsheets for the categories below.

3.2.3.26 Fossil Fuel Combustion – Residential – Liquified Petroleum Gas (LPG)

a. Source Category Description 

Residential LPG Combustion is liquefied propane gas that is burned in residential 

housing. Common uses of energy associated with this sector include space heating, water 

heating, and cooking. 

The general approach to calculating emissions for this SCC is to take State LPG 

Consumption from the EIA and allocate it to the county level using methods described 

below. County level LPG consumption is multiplied by the emission factors to calculate 

emissions. 

For this source category, the following SCC was assigned: 

SCC Descriptor 1 Descriptor 3 Descriptor 6 Descriptor 8 

2104007000 Stationary Source 

 Fuel Combustion 

Residential Liquefied 

Petroleum Gas 

(LPG) 

Total: All 

Combustion Types 

b. Activity Data 

Residential liquefied petroleum gas (LPG) combustion emissions were calculated using 

the volume of LPG consumed in the United States. State-level LPG consumption by 

sector is available from the Energy Information Administration (EIA).1 Year 2006 

consumption data were used as a surrogate for 2008 emissions because these were the 

latest data available when this inventory was prepared. 

State-level LPG consumption was allocated to each county using the US Census Bureau’s 

2000 Census Detailed Housing Information.2 These data include the number of housing 

units using a specific type of fuel for residential heating. State LPG consumption was 

allocated to each county using the ratio of the number of houses burning LPG in each 

county to the total number of houses burning LPG in the State. 

c. Control Factors 

No control measures are assumed for this category. 

d. Emission Factors 

Pollutant emission factors for residential LPG are based on the residential natural gas 

emission factors.3,4,5 For all counties in the United States, the natural gas consumed by 

residential combustion is assumed to have a heating value of 1,020 Btu per cubic foot and 

a sulfur content of 2,000 grains per million cubic feet.3

 Those natural gas emission 

factors originally presented in the units “pounds per million cubic feet” were converted to 

energy-based units using the 1,020 Btu/cubic foot conversion factor. Once all the natural 

gas emission factors were converted to energy-based units, the natural gas emission 
Page 220 

factors were converted to LPG emission factors by multiplying by 96,750 Btu/gallon. 

Some emission factors were revised based on recommendations by an ERTAC advisory 

panel composed of state and EPA personnel. 

e. Sample Calculations 

Emissions are calculated for each county using emission factors and activity as: 

 Ex,p = FCx × EFx,p

where: 

 Ex,p = annual emissions for fuel type x and pollutant p, 

 FCx = annual fuel consumption for fuel type x, 

 EFx,p = emission factor for fuel type x and pollutant p, 

And FCx = AState x (Hcounty / HState) 

where : 

 AState = State activity data from EIA 

 HCounty = number of houses in the county using LPG as the primary heating fuel 

 HState = number of houses in the state using LPG as the primary heating fuel. 

Example: 

Using Allegheny County, PA as an example: 

The State of Pennsylvania had a reported use of 4,743 thousand barrels of LPG in the 

residential sector in 2006. Allegheny County, PA had 4,317 houses out of the state total 

of 145,254 that use LPG as the primary heating fuel. This equates to a share of 2.97% of 

the LPG used for residential heating in the state. From Table 1, CO emission factor is 

159.6 lb/thousand barrels. 

ECO = 4,743 thousand barrels × (4,317 houses / 145,254 houses) 

× 159.6 lb/thousand barrels 

= 22,498 lb CO or 11.25 tons CO

3.2.3.27 Fuel Combustion – Residential- Wood 

EPA created the Residential Wood Combustion tool to assist states with compiling the 

2005 NEI, and has updated the tool with new SCCs to reflect new equipment (certified/ 

non-certified inserts, outdoor hydronic heaters, wood pellet stoves), revised equipment 

population based on regional surveys and American Housing Survey (US Census) data, 

and wood use ratios. 

The tool is a Microsoft Access database with data input tables for appliance types and 

population, fuel inputs, burn temporal profiles, and emission factors. Missouri had no 

state-specific updates to input files, so the EPA defaults for Missouri were used to 

calculate emissions. A specific query performs the calculation and outputs the emission 

table for the state or counties of interest.

3.3 Mobile Source Emissions 

3.3.1 Nonroad Mobile Sources 

Nonroad categories include aircrafts, recreational marine and land-based vehicles, farm 

and construction machinery, industrial, commercial, logging, and lawn and garden 

equipment, and railway maintenance equipment. These equipment are powered by 

compression-ignition engines which are typically diesel-fueled, as well as spark-ignition 

(gasoline-fueled) engines. Compressed natural gas (CNG) and liquefied petroleum gas 

(LPG) engines may also power certain types of nonroad equipment. 

3.3.1.1 Procedures and Methodologies 

For nonroad gasoline, diesel, LPG and CNG sources, NONROAD2008 model, was used 

to calculate nonroad emissions. The Air Program Staff generated off-road mobile 

emissions for the Missouri counties in the St. Louis ozone nonattainment area using the 

fuel and meteorological data from the NCD. The Air Program Staff followed the 2008 

and 2022 modeling protocol submitted by EPA Region 7 to the Department for the 

development of the 2008 off-road mobile emissions with some exceptions. The Staff 

used 3.5% oxygen weight instead of 0.35% and 100% ethanol blend market instead if 

10%. The modeling protocol submitted by EPA Region 7 to the Department, for the 

development of the 2008 off-road mobile emissions can be found in Appendix C-4 of this 

document. The data generated by our staff for the 2008 off-road mobile source emissions 

for the Missouri counties in the St. Louis nonattainment area are summarized in Table 14. 

For aircraft, EPA ran the Federal Aviation Administration (FAA) Emissions and 

Dispersion Modeling System (EDMS) using Bureau of Transportation Statistics (BTS) T100 Landing and Takeoff (LTO) and Terminal Area Forecast (TAF) data. The state of 

Missouri did not provide alternate emissions or input data, so EPA calculations were 

accepted. 

For commercial marine vehicles, EPA’s Office of Transportation and Air Quality 

(OTAQ) provided emission estimates based on grown 2002 emissions and 2008 

Locomotive and Marine federal rule making. Again, EPA emission estimates were 

accepted. 

For locomotives, the Eastern Regional Technical Advisory Committee (ERTAC Rail) 

provided emission estimates based on fuel use data from the American Association of 

Railroads (AAR), Surface Transportation Board (STB) Annual Reports, and railroad 

provided fleet and activity information. These estimates were accepted by Missouri. 

EPA generates emissions data for aircraft, commercial marine and locomotive sources 

using a method similar to the way emissions are generated for non-point sources. 
Page 224 

Therefore, 2008 NEI data for aircraft, commercial marine and locomotive emissions, 

which are listed as nonpoint emissions in the NEI data, need to be added to the nonroad 

mobile source category. See Section 3.3.1.4 for emission totals. 

3.3.1.2 List of Source Categories and Emissions 

The list of source categories and emissions in the five-county St. Louis Nonattainment 

Area is provided in Appendix C-5.

3.3.2 Onroad Mobile Sources 

Onroad emission sources are also known as highway sources. They include vehicles used 

on roads for transportation of passengers or freight. The emissions from internal 

combustion engines in these vehicles are included in this category. Emissions of 

particulates entrained by the motion of the vehicle or road contact are included in the 

nonpoint category. 

3.3.2.1 Mobile Model Choice 

EPA released the Motor Vehicle Emissions Simulator (MOVES) in December of 2010, 

and MOVES is now the official model to use for mobile emissions modeling. MOVES 

was chosen because it is the official model for future inventories and to ensure that any 

future year emissions and budgets will be calculated consistently. 2008 mobile emissions 

were initially created using Mobile6.2 via NMIM for the St. Louis nonattainment area for 

the purpose of submitting state wide emissions data for EPA’s 2008 National Emissions 

Inventory (NEI). The NMIM NCD input data was updated with Missouri specific 

information. Local VMT data, vehicle registration distributions, and meteorology data 

from the updated NCD were converted to MOVES formatting using EPA provided 

conversion workbooks. 

MOVES is a completely redesigned model, not just an updated version of the previous 

Mobile model. The way MOVES calculates emissions has changed to reflect EPA’s more 

current understanding of the emissions produced by vehicles and the various factors that 

affect the emissions. NOX emissions were found to be higher because of the larger 

portion extended idling of heavy duty vehicles contributes to the emissions total. PM2.5

emissions were also higher because of a better understanding of the effect of stop and go 

traffic, which has a significant impact on emissions in highly urban areas, such as the St. 

Louis nonattainment area. As a result of these changes to the model, MOVES produced 

higher emissions estimates for 2008 than were originally created with NMIM. 

3.3.2.2 Mobile Model Inputs 

Local VMT data was gathered from East-West Gateway at the county level. This data is 

listed in 
Page 226 

Table 17. 

On-road mobile source emissions for 2008 were calculated using MOVES version 2010a. 

The emissions for 2008 were calculated using 2008 VMT data provided by the East West 

Gateway Council of Governments. The 2008 VMT data was originally generated from 

the Missouri Department of Transportation for state-owned roads, and then East-West 

Gateway used their Traffic Demand Model to calculate the actual local VMT data for 

each of the five counties on the Missouri side of the St. Louis Ozone nonattainment area. 

The road type distribution input used in 2008 was developed from the National County 

Database (NCD) to distribute the county level VMT to road type. EPA’s VMT converter 

workbook was then used to produce MOVES input tables. A vehicle registration 

distribution for 2008 was originally created for the National Mobile Inventory Model 

(NMIM) using registration data from Missouri’s Department of Revenue (registration 

data shown in Table 18). The vehicle distribution was converted to a MOVES age 

distribution table using EPA’s VMT converter workbook. The registration data was also 

used to create the MOVES vehicle population input tables for 2008. Vehicle counts were 

converted from Mobile 6.2 vehicle classes to MOVES source types using the source type 

fractions from the Source Type Pop Fractions table in EPA’s VMT converter workbook. 

The meteorology data used for 2008 was developed by EPA from National Weather 

Service data. Inspection and Maintenance (I/M) input tables were developed to 

characterize the Gateway Vehicle Inspection Program (the I/M program in place in the St. 

Louis Ozone nonattainment area). Additional details regarding the development of the 

I/M input can be found in the I/M input table development protocol in Appendix B. 

MOVES base data was used for all other inputs to calculate the 2008 on-road mobile 

source emissions, after reviewing the data to ensure accuracy. The base fuel supply tables 

in MOVES were used for the runs, as they already took into account the reformulated 

gasoline used in the St. Louis nonattainment area. A separate input database was created 

for each county, using county specific data where possible. All of the data used to 

develop the county database manager inputs for the MOVES runs performed for 2008, 

other than the data for county database manager inputs where EPA default data was used, 

can be found in Tables 19 - 34 below. 

The MOVES model runs were set up selecting all available gasoline and diesel fuel 

vehicle type combinations, all months, days, hours, and all road types. A separate run was 

set-up for each pollutant and each county. All pollutant processes were selected in each 

run, but the VOC emissions from MOVES emission processes 18 and 19 (refueling 

displacement emissions, and refueling evaporative emissions) were removed during the 

post model analysis as these are refueling emissions, which are classified as area source 

emissions, and are not included in the mobile source emissions inventory (See subsection 

3.2.3.24). The emissions were post-aggregated to the month level using MOVES. 

Separate runs were performed for each county and each pollutant. Once the MOVES 

input tables had been created, MOVES was run and all months for 2008 were selected to 

create an annual emissions profile. The VOC emissions for the months of April through 
Page 227 

October were totaled and divided by 214, the number of days in those months, to give 

average ozone season day VOC emissions for 2008.

4.0. Quality Assurance/Quality Control 

4.1 Point Source QA/QC and Results 

Prioritization 

The EI Unit prioritizes review of those facilities that have the largest bulk emissions, 

specifically facilities with a Part 70 or Intermediate operating permit. While every data 

element collected helps to characterize the emission estimate, in evaluating the data, 

those fields most directly tied to the emissions calculation are given the highest priority. 

The MoEIS database system itself was quality assured to provide smooth data transfer 

from the state inventory to the NEI. 

Methods 

The EI Unit’s general QA procedures utilize any and all of the techniques outlined in the 

EPA’s Emission Inventory Improvement Program (EIIP) Technical Report Series 

Volume 6: Quality Assurance Procedures. The unit groups these techniques into two 

basic categories: Phase I, or Bottom-Up QA procedures, and Phase II, or Top-Down QA 

procedures. Top-Down Procedures analyze groups of emissions data that share a 

common trait and look for outliers, in keeping with the ‘Reality Check’ technique. 

Bottom-Up Procedures evaluate individual EIQs that are believed to be erroneous, 

whether due to a top-down analysis, errors found when entering the EIQ into the 

database, or inconsistencies brought to the attention of the EI Unit by a third party. These 

bottom-up procedures utilize the ‘Peer Review’, the ‘Sample Calculations’, or the 

‘Independent Audit’ techniques. Note that any of these techniques could be found in 

either category; they have simply been mentioned in reference to the category in which 

they are most often found. 

Quality checks are completed using computerized checks in the MoEIS automated 

system, exploiting its utility in ensuring that the necessary data is reported, and in 

providing an acceptable numeric range for certain fields. It streamlines the process of 

ensuring that all data fields required for the EPA’s EIS system are present, are compatible 

with, and meet the needs of the EPA system. For example, emission release point records 

that were missing fields were corrected with the input of emission modelers and facility 

staff. Outdated Source Classification Codes (SCC), units of measure, and control device 

codes were removed, and required data fields for stack emission release points were 

added. 

Phase I reviews address individual EIQs to reconcile discrepancies with emission data. 

Phase I reviews are generally done only on hardcopy submitted EIQs, but may also be 

done based on priority. Examples of EIQ issues that were encountered include 

throughputs and emission factors with inconsistent units of measure, emission unit 

identifiers that are different from previous EIQs, and MoEIS-calculated emissions that 

differ from the emissions on the hardcopy forms. Technical staff conducting these 

reviews worked with the companies to make corrections to their EIQs and place written 
Page 250 

documentation of all changes in the hardcopy EIQ files stored in the fileroom. In 

addition, all changes made to EIQs are tracked in an electronic log file. 

Phase II reviews take a top-down look at the emissions data. This phase involves running 

Access queries to identify potential issues to investigate further. The Phase II QA queries 

included ensuring condensable particulate emissions were reported, ensuring correct 

application of sulfur/ash content in emission factors, and reviewing emission trends by 

facility and industry type to identify any anomalies. In addition, point source data from 

other databases incorporated by the EPA into the EIS, such as the Toxics Release 

Inventory (TRI) and the Clean Air Markets Division (CAMD), will be reviewed and 

compared to MoEIS data. Prioritization of the largest sources, largest changes, and 

largest anomalies is a top consideration, as is realizing a meaningful emission difference 

within a reasonable amount of time. Any changes made to EIQs during the Phase II QA 

process will be done with input from the companies, and written documentation of all 

changes will be placed in the EIQ files stored in the fileroom and in electronic files. 

Results 

CAMD Data Comparison: Several emission units in Missouri are subject the Acid Rain 

Program or the NOx Budget Trading Program, and these units report SOx and NOx

emissions directly to EPA’s Clean Air Markets Division (CAMD). These units were 

reviewed to ensure the same emission quantities were reported to EPA and to the APCP 

in their annual emissions report. Over 70% of all EIQ-reported SOx and NOx emissions 

were quality assured with the help of the CAMD database. Since the naming of the units 

between the two databases is not always identical, and not all units reported to the APCP 

are required to report to CAMD in either individual or grouped format, some manual 

analysis was done to compare emissions reported to the two databases. 

The largest difference noted between the two databases was an underreporting of almost 

270 tons to MoEIS compared to CAMD. Contact with the facility showed that the cause 

was a transcription error, and the MoEIS data was corrected. Due to prioritization, the 

six other facilities that showed reporting differences were not addressed, and their total 

difference was not more than the single NOx correction that was completed. 

Condensable PM Reporting: Missouri facilities were not required to report condensable 

emissions prior to emission year 2008, but they were reminded to report condensable 

starting with emission year 2008 in email or postcard form and in the EIQ packet. The 

inclusion of condensable PM data in the 2008 emission reporting year is important 

because it is an EPA triennial inventory year where data will be extensively quality 

assured for use in detailed air quality analyses and planning. Missouri is required to 

report condensable PM emissions in 2009 by EPA’s Air Emissions Reporting Rule 

(AERR), 40 CFR Part 51.15, and data collection systems for separate condensable and 

filterable PM reporting in 2009 are in place. Quality assurance of the 2008 emissions 

data began with Part 70 and Intermediate operating permit holders who use Source 

Classification Codes (SCCs) that have condensable emission factors in the webFIRE 

emission factor database. 
Page 251 

Identifying facilities: There are many fuel combustion processes that produce 

condensable emissions. For the vast majority of fuel combustion processes, the 

condensable emissions are accounted for in the total PM10 and PM2.5 emission 

factors already in use. This is especially true for natural gas, diesel, and fuel oil 

combustion sources. Coal combustion sources, on the other hand, required 

additional analysis to determine if condensable emissions were included in the 

report. Six facilities correctly included condensable in their initial emission report 

and were contacted to verify those emissions. Seven facilities were identified that 

may not have included condensable emissions, but the omission did not amount to 

over 10 ton underreporting. Seventeen facilities that did not report condensable 

emissions were the highest priority and were contacted from August to October 

2009 to correct their emission reports. 

Emission Results: Condensable PM emissions added to those seventeen facilities 

account for over 3,700 tons of PM10 emissions statewide.

Ash/Sulfur Changes: The method of calculating emissions in MoEIS was changed from 

2007 to the 2008 emission year. The previous equation used the throughput, emission 

factor, ash or sulfur content, and control efficiency to calculate emissions. The ash or 

sulfur term was added to the equation to assist facilities whose emission factor is an 

equation from AP-42 in the form [EF * A/S]. While the calculation method worked well 

for a limited number of facilities, it became a source of confusion for the larger group, 

and misinterpretation of the emission factor term by Air Program users necessitated a 

change to the calculation to remove the ash or sulfur term from the calculation. 

Communication of the change to facilities was done via the EIQ mailout and notations in 

the MoEIS online system. A review of submitted EIQs to ensure all affected facilities 

had accounted for the new calculation method showed only one facility that did not adjust 

the emission factor to account for the change. They were contacted to make the 

correction and it resulted in an over 4,000 ton increase in SOx emissions compared to 

their initial report. 

Interannual Variability- Facilities that reported over 20 tons of chargeable emissions 

were examined to find sources with large interannual variability. A list of 20 facilities 

was generated where plantwide chargeable emissions changed by more than 20%, and 

each of these facilities were contacted to verify the source of the increase or decrease. 

Four facilities reported an emission change due to emission factor or control device 

changes, and the other 16 facilities reported throughput changes were the cause of the 

emission differences. Since the cause of the emission variability has been documented, 

there is no cause for changes to the emissions report for these twenty facilities. 
Page 252 

Local Agency QA – Four facilities in St. Louis City were selected for a detailed audit 

based on their level of emissions and variation from past year reporting. At the four 

facilities, over 20 emission units were audited to confirm throughput, appropriate 

emission factor use, appropriate control efficiency application, permitted equipment 

limits, and number of pollutants. Six emission units were found to be incorrectly 

reported in the 2008 emission report, with one facility having overreported almost 10 tons 

of PM10, and another underreported 40 tons facility-wide. Phase 1 quality assurance steps 

were used on 14 facilities in Springfield, 7 facilities in St. Louis County, and twenty 

facilities in Kansas City. Throughputs, emission factors, incorrect calculations, and HAP 

reporting were reviewed for these sites. 

Stack Parameters – In preparation for point source data submission to the NEI, the 

required data elements for stack emission release points were queried to ensure the data 

submittal could occur without errors. Of the over 2,600 stack release points associated 

with point source emission reports that are submitted to the 2008 NEI, almost 50% 

required quality assurance before they could be submitted. Three main quality assurance 

steps were taken to correct the stack data: missing data elements were filled in as 

possible, data elements that were out of range were quality assured, and previously 

submitted NEI data elements were compared to current Missouri emission report data to 

identify discrepancies. Filling in missing data elements took the most time because it 

required review of modeling files, contact with local agency staff, or contact with the 

facility. Out of range data elements were a much smaller portion of the quality 

assurance, but these were also corrected via modeling files and contact with the facility. 

Discrepancies between the EIS and 2008 Missouri EIQ data were reconciled by accepting 

the Missouri data instead of EIS data. 

4.2 Nonpoint Source QA/QC 

EI Unit staff has documented the following information for each nonpoint source 

category: source of data for activity, emission factors, allocation methodologies, nonpoint 

source SCCs covered, pollutants covered, and point source subtraction in Table 11. 

Much of the documentation for EPA categories appears at the NEI website: 

http://www.epa.gov/ttn/chief/net/2008inventory.html

Emission inventory staff participated in the ERTAC workgroup that developed many of 

the updated emission factors and methodologies used for 2008 emission estimates, and 

the resulting emission factors were checked against those used in EPA templates for 

accuracy. All nonpoint source categories in the 2008 NEI will be reviewed, including 

those for which EPA is developing emissions estimates. The emission estimates were 

compared to the 2005 NEI to identify outlying or missing categories. 

Quality checks of the EPA excel worksheets showed that three worksheets had incorrect 

emission factors when compared to the ERTAC summary emission factor page, and these 

were corrected before emissions were submitted. Several categories had spreadsheet 
Page 253 

templates that omitted HAP calculations, and these were amended prior to completing the 

categories. Spot checks were also done on the calculation pages to ensure formulas were 

followed, and no problems were found. 

Quality assurance of the data included checks against 2002 NEI data submissions, and 

completeness checks for the number of counties, number of pollutants, order of 

magnitude, and correct units of measure. The priority data checks showed no errors, but 

there are a few source categories included in the 2002 NEI that were not included in the 

2008 NEI due to time constraints (see section 3.2). 

There are also a few categories that show large differences (>50%) between the 2002 NEI 

and the 2008 NEI, and virtually all are due to changes in emission factors, activity data, 

controls, covered categories, or calculation methods. The largest differences between the 

2002 and 2008 NEI come in the graphic arts, degreasing, industrial surface coating, 

miscellaneous non-industrial solvents, and gas stations. The methods and source data for 

the graphic arts category have changed significantly between 2002 and 2008, and the 

source of activity data for 2002 did not cover all categories because of restricted release 

census bureau data. The emission factor for degreasing decreased by 50% from 2002 to 

2008 after EPA and ERTAC review. The industrial surface coating category was 

assumed zero in 2002 but is non-zero in 2008. The miscellaneous non-industrial category 

did not have emissions for portable residential and commercial gas cans in 2002, but that 

category is included in 2008. Gas stations show a decrease in emissions from 2002 to 

2008 that can be attributed to additional controls in the interim years. None of the large 

differences between 2002 and 2008 can be attributed to errors in the 2008 inventory that 

need correction. 

4.3 Mobile Source QA/QC 

4.3.1 Nonroad Source QA/QC 

Per Appendix C-4, quality control and quality assurance were conducted throughout the 

nonroad modeling process. Data collected from various data sources were verified and 

correctly entered or transcribed into the model. In some instances, input values, i.e., 

temperatures and fuel values were double and/or triple checked for accuracy to insure 

they corresponded to Missouri DNR data. In addition, a spot-checking of the modeling 

results, including rerunning the model for those results in question, was performed to 

ensure reliability. 

4.3.2 Onroad Source QA/QC 

The data used for the modeling was originally collected for creating the 2008 NEI. 

Missouri DNR has conducted extensive quality assurance on the model inputs and the 

inputs have been reviewed by EPA. The inputs were converted to MOVES formatting 

using EPA conversion tools. The MOVES converted data was double and/or triple 

checked to ensure accuracy. In addition, a spot-checking of the modeling results, 
Page 254 

including rerunning the model for those results in question, was performed to ensure 

reliability.

St. Louis, Missouri-Five County Area

Nonroad modeling for inventory development

For this modeling exercise, the EPA Region 7 utilized the NONROAD2008a model to calculate

an ozone and PM2.5 nonroad inventory in five counties in the St. Louis nonattainment area for

the 1997 PM2.5 annual and 1997 Ozone NAAQS. The NONROAD2008a model provides the

emissions for all nonroad source categories except aircraft, commercial marine vessel, and

railroad locomotive.

In running the NONROAD model, the user must specify a modeling scenario by the inventory

year, geographic area (nation, state, county), period (annual, seasonal, monthly, daily), and the

equipment categories. For all other required variables, the NONROAD model provides default

input values. For the following modeling exercises, fuel parameters (Reid Vapor Pressure

(RVP), oxygen weight, sulfur content, ethanol volume and market percentage) and temperatures

for each geographical area were provided by MDNR in lieu of the modeling default settings for

more accurate results (see attachment).

Ozone Precursor Emissions

Ozone Methodology/Input Data

Nonroad mobile source emissions for the years of 2008 and 2022 are calculated using the EPA

approved model, NONROAD2008a, and included Franklin County, Jefferson County, St.

Charles County, St. Louis County and St. Louis City in St. Louis, Missouri.

For modeling ozone precursor pollutants, temperatures and fuel characteristics representative of

each county during an ozone summer weekday, were entered into NONROAD2a and modeled to

calculate an ozone season weekday emissions for nonroad sources. Minimum, maximum, and

average temperatures for a typical summer season were provided by MDNR (see attachment).

Direct PM2.5 / PM2.5 Precursor Emissions

Methodology/Input Data

Nonroad mobile source emissions for the years of 2008 and 2022 were calculated using the EPA

approved model, NONROAD2008a, and included Franklin County, Jefferson County, St.

Charles County, St. Louis County and St. Louis City in St. Louis, Missouri.

For modeling PM2.5 and PM2.5 precursor pollutants, temperatures and fuel characteristics

representative of each county for each of the four seasons (winter, spring, summer, and fall) were

entered into the NONROAD2008a model as input parameters. The highest temperature and

lowest temperature from each three month period (December-February, March-May, JuneAugust, and September-November) were averaged to create a seasonal average temperature.

Those seasonal average temperatures, seasonal minimum and seasonal maximum temperatures

were then utilized in the model, including the fuel parameters, to calculate the total emissions for

each county and season. Summing the emissions of all four seasons for each county gave the

total annual emissions. The temperatures and fuel characteristics representative of each county

were provided by MDNR. Modeling input parameters are as follows:

QA/QC

Quality control and quality assurance were conducted throughout this nonroad modeling process.

Data collected from various data sources were verified and correctly entered or transcribed into

the model. In some instances, input values, i.e., temperatures and fuel values were double

and/or triple checked for accuracy to insure they corresponded to the data supplied by MDNR.

In addition, a spot-checking of the modeling results, including rerunning the model for those

results in question, was performed to insure reliability.

1.0 INTRODUCTION 

1.1 What is the National Emission Inventory? 

 The National Emission Inventory (NEI) is a comprehensive inventory covering all 

anthropogenic sources of criteria pollutants and hazardous air pollutants (HAPs) for all areas of 

the United States. The NEI was created by the U.S. Environmental Protection Agency’s 

Emission Inventory and Analysis Group (EIAG) in Research Triangle Park, North Carolina. The 

NEI will be used to support air quality modeling and other activities. To this end, the EPA 

established a goal to compile comprehensive emissions data in the NEI for criteria and HAPs for 

mobile, point, and nonpoint sources. This report presents an overview of how emission estimates 

for the aircraft component of the NEI were compiled. 

1.2 Why Did the EPA Create the NEI? 

 The Clean Air Act (CAA), as amended in 1990, includes mandates for the EPA related to 

criteria and hazardous air pollutants. The CAA defines criteria pollutants as being one of the 

following air pollutants: 

 Carbon monoxide (CO); 

 Sulfur oxides (SOx); 

 Nitrogen oxides (NOx); 

 Ozone; and 

 Particulate matter (PM). 

 Hazardous air pollutants are also delineated in the CAA, see 

http://www.epa.gov/ttn/atw/188polls.html for a complete list of regulated pollutants and their 

chemical abstract service [CAS] numbers. 

 The CAA requires the EPA to identify emission sources of these pollutants, quantify 

emissions, develop regulations for the identified source categories, and assess the public health 

and environmental impacts after the regulations are put into effect. The NEI is a tool that EPA 

can use to meet the CAA mandates. In this report, criteria and HAP emission estimates are 

discussed for aircraft sources. 

1.3 How is the EPA Going to Use This Version of the NEI? 

 It is anticipated that the emission inventory developed from this effort will have multiple 

end uses. The data have been formatted according to protocols established for the EPA’s NEI 

submittals. The common data structure on which the NEI platform is based will allow the NEI 

emission data to be transferred to multiple end-users for a variety of purposes. 
1-2 

The criteria and HAP emission estimates developed for the NEI will be used to evaluate 

air pollution trends, air quality modeling analysis, and impacts of potential regulations. 

1.4 Report Organization 

 Following this introduction, Section 2.0 provides information on how the national aircraft 

emission estimates were developed. This inventory effort was coordinated by the EPA’s Office 

of Transportation and Air Quality (OTAQ) and EIAG. The appendixes were created to provide 

the supporting references from OTAQ. 
2-1 

2.0 DEVELOPMENT OF THE AIRCRAFT COMPONENT FOR THE 

NEI 

2.1 How does this aircraft study fit into the NEI? 

 The NEI was developed to include all point, nonpoint (sometimes referenced as “area”), 

and mobile sources. The approaches used in the point and nonpoint source categories are 

documented in other reports. Table 2-1 summarizes the approaches used to estimate emissions 

from all nonroad sources included in the NEI program. Those source categories and years that 

are included in this report are noted in bold. 

 The scope of this inventory component of the NEI was to compile criteria and HAP 

emissions data for aircraft operating in United States air space. In this effort, national emission 

estimates were often developed as point sources for each airport. The methodologies used to 

estimate emissions are discussed in this report. 

The target inventory area includes every state in the United States and every county 

within a state, including Washington, DC, Puerto Rico, and US Virgin Islands. There are no 

boundary limitations pertaining to traditional criteria pollutant nonattainment areas or to 

designated urban areas. The pollutants inventoried included all criteria pollutants (and the 

188 HAPs identified in Section 112(b) of the CAA). 

 In addition to numerous specific chemical compounds, the list of 188 HAPs includes 

several compound groups [e.g., individual metals and their compounds, polycyclic organic 

matter (POM)]; the NEI includes emission estimates for the individual compounds wherever 

possible. Many of the uses of the NEI depend upon data (e.g., toxicity) for individual compounds 

within these groups rather than aggregated data on each group as a whole. 

 The intent in presenting the following emission inventory approach is to provide 

sufficient and transparent documentation such that states and local agencies can use these 

approaches, in conjunction with their specific local activity data to develop more accurate and 

comparable emission estimates in future submittals. 

This documentation is not meant to provide an exhaustive analysis on the derivation of all 

the inputs. For example, an emission factor used for a national estimate may be given in the 

appendix, but the source test data that were evaluated to obtain this factor may not be presented 

or discussed. The goal of the documentation provided is to show in a brief and concise manner 

how a given estimate was derived.

2008 All Criteria, HAPs US, Puerto Rico, Virgin Islands Emission estimates for all pollutants were developed using EPA’s National Mobile 

Inventory Model (NMIM), which uses MOBILE6 (specifically, M6203ChcOxFixNMIM.exe) to calculate onroad emission factors. Where States provided alternate onroad MOBILE6 inputs or VMT, these data replaced EPA default inputs. Default VMT is based on FHWA 2008 data and 2008 Census population estimates. 

2005 All Criteria, HAPs US, Puerto Rico, Virgin Islands Emission estimates for all pollutants were developed using EPA’s NMIM, which uses 

MOBILE6 to calculate onroad emission factors. Where States provided alternate

2-11 

2.2 What are Aircraft Sources? 

The aircraft source category includes all aircraft types used for public, private, and 

military purposes. This includes four types of aircraft (EPA, 1992): 1) Commercial; 2) Air Taxis; 

3) General Aviation; and 4) Military. 

Commercial aircraft include those used for transporting passengers, freight, or both. 

Commercial aircraft tend to be larger aircraft powered with jet engines. Air Taxis (AT) carry 

passengers, freight, or both, but usually are smaller aircraft and operate on a more limited basis 

than the commercial carriers. General Aviation (GA) includes most other aircraft used for 

recreational flying and personal transportation. Aircraft that support business travel, usually on 

an unscheduled basis, are included in the category of general aviation. 

The national AT and GA fleet includes both jet and piston-powered aircraft. Most of the 

AT and GA fleet are made up of piston powered aircraft, though smaller business jets can also be 

found in these categories. According to a 2008 Federal Aviation Administration GA and AT 

Activity Survey, 66% of all GA and AT activity are powered by piston-powered aircraft and 

34% are jet (or turbine) driven. EPA has used this estimate as a national-scale default value in 

recently published studies investigating lead emissions from aviation sources (EPA, 2008). The 

piston powered aircraft tend to have higher VOC, PM, and CO emissions and lower NOX

emissions than larger jet-powered aircraft (EPA, 1992). Military aircraft cover a wide range of 

aircraft types such as training aircraft, fighter jets, helicopters, and jet- and a small number of 

piston powered planes of varying sizes. 

It should be noted that this inventory effort also includes criteria and Hazardous Air 

Pollutants (HAP) emission estimates for aircraft Auxiliary Power Units (APU) and aircraft 

Ground Support Equipment (GSE) typically found at airports, such as aircraft refueling vehicles, 

baggage handling vehicles, and equipment, aircraft towing vehicles, and passenger buses. 

2.3 What Pollutants are Included in the National Emission Estimates for Aircraft? 

Emissions estimates were developed for all criteria pollutants including volatile organic 

compounds (VOC), nitrogen oxides (NOx), carbon monoxide (CO), sulfur oxides (SOx), 

particulate matter less than 10 microns (PM10), particulate matter less than 2.5 microns (PM2.5) 

and hazardous air pollutants (HAP) (Cook, 1997; Cook, 1998; EPA/FAA, 2009). The HAPs that 

are included in the national aircraft inventory are shown in Table 2-2 and are based on available 

test data and accepted emission estimation procedures.

2.4 How Were the Aircraft Emissions Estimated? 

EPA has developed guidance for inventorying aircraft emissions associated with an 

aircraft’s landing and takeoff (LTO) cycle. The cycle begins when the aircraft approaches the 

airport on its descent from cruising altitude, lands, taxis to the gate, and idles during passenger 

deplaning. It continues as the aircraft idles during passenger boarding, taxis back out onto the 

runway for subsequent takeoff, and ascent (climbout) to cruising altitude. Thus, the five specific 

operating modes in an LTO are (EPA, 1992): 1) Approach; 2) Taxi/idle-in; 3) Taxi/idle-out; 

4) Takeoff; and 5) Climbout. 

The LTO cycle provides a basis for calculating aircraft emissions. During each mode of 

operation, an aircraft engine operates at a fairly standard power setting for a given aircraft 

category. Emissions for one complete cycle are calculated using emission factors for each 

operating mode for each specific aircraft engine combined with the typical period of time the 

aircraft is in the operating mode. 

On March 20, 2009, the EPA posted preliminary LTO data intended to be will use to 

calculate emissions for review prior to developing the aircraft inventory. State and local agencies 

were encouraged to review the materials posted at ftp://ftp.epa.gov/EmisInventory/2008_nei/ and 

provide comments on any necessary corrections to: 
2-13 

 Airport names and locations for approximately 20,000 airports to be included in the 

Emission Inventory System (EIS) facility inventory; 

 Landing and Takeoff (LTO) information that will be used to estimate emissions for 

each airport; 

 Aircraft/engine combinations to link to FAA LTO data including default assumptions 

and AircraftEngineCodeTypes for EIS submittals; and 

 Lead estimates and lead estimation methodology. 

This preliminary review by state, local, and tribal groups provided information that EPA used to 

improve EPA’s work. EPA received comments from four states (i.e., Minnesota Pollution 

Control Agency - Environmental Analysis and Outcomes Division; New Jersey Department of 

Environmental Protection; Bureau of Air Management, Connecticut Department of 

Environmental Protection; and Wisconsin Department of Natural Resources (specifically related 

to Volk Field Air National Guard Base (VOK) in Juneau County Wittman Regional Airport 

(OSH)) and three local agencies (i.e., Mecklenburg County North Carolina; Ventura County 

California Air Pollution Control District (Specifically related to Oxnard (OXR), Camarillo 

(CMA) and Santa Paula (SZP); and - Regional Air Pollution Control Agency (Dayton and 

Montgomery County Ohio)). 

Criteria emission estimates are presented here for four different aircraft types: 

commercial air carrier, air taxis, general aviation, and military. HAP emission estimates were 

developed for all aircraft types. 

Emissions for commercial air carriers for which detailed aircraft-specific activity data 

were available, were calculated differently than the other three aircraft categories (See Figure 2-

1). Criteria and HAP emissions were estimated for commercial aircraft by applying aircraft make 

and model (e.g., Boeing 747-200 series) specific LTO activity data from FAA’s Form 41, 

Schedules T100 and T100(f) Air Carrier Data to the FAA’s Emissions and Dispersion Modeling 

System (EDMS), Version 5.1 (DOT, 2008). It should be noted that due to the reporting 

requirements of T-100, only commercial activities are included in the dataset, and therefore does 

not include activity data for non-air carrier applications such as general aviation and military. 

This distinction lead to a revision to EPA’s original aircraft crosswalk table, also known as the 

aircraft engine type code, used to match aircraft to EDMS aircraft and to account for double 

counting between the T-100 data and the TAF data. In the revised crosswalk, aircraft that were 

previously considered general aviation and military based on aircraft model were changed to air 

taxi and commercial air carrier aircraft types based on the definition of air taxis (i.e., any aircraft 

that was not considered an air taxi was classified as an air carrier aircraft). The FAA reviewed 

the cross walk tables and made additional changes that moved some of the larger air taxis to the 

commercial air carrier category and some of the smaller commercial air carriers to the air taxi 

category. The revised crosswalk table is provided in an electronic file as supporting data for this 

study. 
2-14 

Emissions were calculated for each airport individually using airport specific mixing 

height. The national-scale default values for taxi in and out are seven and nineteen minutes, 

respectfully. It should be noted that EDMS incorporates the latest aircraft engine emission 

factors from the International Civil Aviation Organization Engine Exhaust Emissions Data Bank. 

The EDMS output includes organic HAPs, but not metals.

which T-100 data were available were estimated by EDMS, using the assumptions and defaults 

incorporated in the model. This is significant change from previous NEI year’s emissions where 

GSE estimates came from the NONROAD model and APUs were not included in EPA’s 

estimates. With EDMS, GSE that are assigned to an aircraft are given times (minutes per arrival, 

minutes per departure) based upon the type of service. For example, a fuel truck servicing a large 

commercial aircraft will have a different operating time than the same fuel truck servicing a 

commuter aircraft. All EDMS defaults for GSE duration and type (e.g., fuel truck, cabin service 

truck, baggage belt loader) were used. GSE emission factors used by EDMS are derived from 

EPA’s NONROAD2005 model and are based on the following variables: fuel, brake horsepower 

and load factor. GSE engines burn gasoline, diesel, compressed natural gas (CNG), and liquefied 

petroleum gas (LPG). EPA has used a national-scale value to characterize engines type. The GSE 

engine distribution is shown below in Table 2-3. Like GSE, APU emissions are the product of 

operating time. The purpose of an aircraft APU is to provide power to start the main engines and 

run the heating, cooling, and ventilation systems prior to starting the main engines.

Emissions of criteria pollutants for air taxis, general aviation, and military aircraft were 

calculated by combining aircraft operations data from FAA’s Terminal Area Forecasts (TAF) 

and 5010 Forms. To avoid double counting between the T-100 data set and the TAF/5010 data, 
2-15 

LTOs by airport and aircraft type were summed in the T-100 data and compared with data in the 

TAF/5010 data. If the TAF/5010 LTO estimates were larger than the T-100 estimates for a 

specified aircraft type then the T-100 values were subtracted from the TAF/5010 values. If the 

T-100 values were larger than the TAF values, then the TAF values were set to zero. A data set 

of adjusted TAF/5010 LTOs were provided to OTAQ where additional adjustments were made 

to address older data in the TAF and 5010 datasets and to incorporate other insights provided by 

FAA reviewers. 

The TAF/5010 LTO data were dividing into jet and piston powered fractions based on the 

national observation that 66 percent of all general aviation and air taxi activities are associated 

with piston powered aircraft and the remaining 34 percent of general aviation and air taxi 

activities are associated with jet powered aircraft. The adjusted and split TAF/5010 activity data 

were applied to emission factors as appropriate (See Figure 2-2). It should be noted that EDMS 

calculates organic HAP emissions in the model (metal HAPs are currently not included in the 

EDMS output). HAP emission estimates for air taxis, general aviation, and military aircraft were 

estimated by applying speciation profiles to VOC or PM10 emissions estimates. The following 

equation was used (emission factor are included as Appendix A). 

Eixj = LTOi × FRpro-i × EFij

Where: 

Eixj = Emission estimate for aircraft type i equipped with engine type x 

and pollutant j (lbs/year) 

LTOi = Annual count of LTO cycles for aircraft type i 

FRx = Fraction of LTOs equipped with engine type x 

EFij = Generic emission factor for aircraft type i equipped with engine 

type x and pollutant j (lbs/LTO) 

i = Aircraft type (i.e., air taxi, general aviation, and military) 

x = Engine type (i.e., jet or turboprop, and piston engine) 

j = Criteria pollutant j

Lead emission estimates were handled differently. Lead emissions are associated with 

leaded aviation fuel used in piston driven aircraft associated with general aviation. Lead 

emissions per LTO are calculated using the following equation: 

Pb(tons) = (piston-engine LTO) (7.34 g Pb/LTO) (0.95) / 907,180 (g/ton) 

Where the lead content of aviation gasoline is assumed to be 0.56 grams per liter or 

2.12 grams per gallon. 

In flight lead emissions were calculate based on national aviation gasoline consumption 

and similar assumptions noted above about lead fuel content and retention rates. Lead emissions 

associated with airport LTO activities were subtracted from the national fuel based lead 

emissions to approximate in flight lead emissions which were allocated to individual counties 

and noted with the code 777. 

For additional details on EPA lead emission calculation procedures see Calculating 

Piston-Engine Aircraft Airport Inventories for Lead for the 2008 National Emissions Inventory 

(included in Appendix B). 

HAP Emission Estimates 

As noted earlier, EDMS calculates organic HAP emissions for aircraft activity reported in 

the T-100 dataset. Representative HAP speciation profiles were used to estimate the individual 

chemical species for each aircraft type included in the TAF/5010 dataset. Profiles are used to 

split (or speciate) organic gases, hydrocarbons, and particulate matter emissions estimates into 

more individual HAP compounds using the following equation: 

Eixj = LTOix × SPixj

Where: 

Eixj = Emission estimate for aircraft type i equipped with engine type x 

and pollutant j (tons/year) 

LTOix = Annual count of LTO cycles for aircraft type i and engine type x 

SPixj = Generic speciation profiles for aircraft type i equipped with engine 

type x and pollutant j (tons/LTO) 

i = Aircraft type (i.e., air taxi, general aviation, and military) 

x = Engine type (i.e., jet or turboprop, and piston engine) 

j = Pollutant j 

Appendix A contains the HAP profiles converted to emissions factors used for this 2008 

inventory. In this version of the NEI aircraft emissions inventory the following corrections to the 

HAP emission estimates were made: 

 Acenpthylene was removed from this inventory for SCC 2275050012. 
2-17 

 To avoid double counting total xylene emissions were removed if speciated xylene 

factors were also available. 

2.5 How Were Emissions Allocated? 

For the 2008 inventory, emissions were individually estimated for each airport. A GIS 

database obtained from the Bureau of Transportation Statistics (BTS) contained airport level data 

with latitude and longitude coordinates. 

2.6 QA/QC 

Given the significant methodological changes over previous inventory efforts, several 

quality checks were implemented to ensure that these data were developed and allocated in a 

clear and reproducible manner. Some of the quality checks implemented include the following: 

Emissions allocations and estimations 

 All original data importations and transcriptions into the database were doublechecked for errors. 

 All calculation methods and approaches were evaluated for technical soundness. 

 All unit conversions and equations used to generate results were double-checked for 

errors. 

 All sources of original data are referenced in the spreadsheet. 

 Emission factors were compiled from a variety of sources. Each emission factor 

development methodologies were evaluated to identify the most accurate emission 

factor for use in this inventory effort. 

 Emission sums were evaluated across activity types (e.g., Aircraft, APU, and GSE) to 

ensure they consistently mirror LTO activity levels. 

 2008 pollutants and emissions were checked against the 2005 inventory to identify 

any missing pollutants or major changes compared to previous inventories. 

Discrepancies were investigated and revisions were made as needed. 

 The validity of SCC codes, FIP county codes, and pollutant codes were confirmed. 

 The validity of Airport and plane identification codes were confirmed. 

2.7 What are the Results? 

Table 2-4 summarizes the emission estimates for Aircraft, ground support equipment and 

APUs for criteria pollutants. Table 2-5 summarizes the emission estimates for individual HAPs. 

Both tables aggregate the data for all states, including the District of Columbia. Note that the 

2008 estimates do not include state submitted emissions data.

Calculating Piston-Engine Aircraft Airport Inventories for Lead for the 2008

National Emissions Inventory

December 2010 

Section 1. Introduction

The main purpose of this document is to describe the methods the Environmental 

Protection Agency (EPA) used to calculate airport lead (Pb) inventories for the 2008 

National Emissions Inventory (NEI).1 These methods focus on the development of 

approaches to estimate piston-engine aircraft activity at airports in the U.S. since the 

activity of this fleet is reported to the Federal Aviation Administration (FAA) as general 

aviation (GA) or air taxi (AT) activity – categories that also include jet-engine aircraft 

activity. The methods described here reflect improvements to the methods used in 

developing the airport-specific piston-engine aircraft inventories in the 2002 NEI and the 

2005 NEI. 

Background information regarding the use of leaded aviation gasoline (avgas) in 

piston-engine powered aircraft is available in other documents.2,3 Briefly, most pistonengine aircraft operations fall into the categories of either GA or AT. Aircraft used in 

GA and AT activities include a diverse set of aircraft types and engine models and are 

used in a wide variety of applications.4 Lead emissions associated with GA and AT 

aircraft stem from the use of one hundred octane low lead (100LL) avgas. The lead is 

added to the fuel in the form of tetraethyl lead (TEL). This lead additive helps boost fuel 

octane, prevent engine knock, and prevent valve seat recession and subsequent loss of 

compression for engines without hardened valves. Today, 100LL is the most commonly 

available type of aviation gasoline in the United States.5 Lead is not added to jet fuel that 

is used in commercial aircraft, most military aircraft, or other turbine-engine powered 

aircraft. Lead emissions from the use of leaded avgas comprised 45% of the national 

inventory for emissions of lead in 2002.6

 Commercial aircraft include those used for scheduled service transporting passengers, freight, or both. 

Air taxis fly scheduled and for-hire service carrying passengers, freight or both, but they usually are smaller 

aircraft than those operated by commercial air carriers. General aviation includes most other aircraft (fixed 

and rotary wing) used for personal transportation, business, instructional flying, and aerial application. 5

This document is organized into eight sections. Section 2 describes the data we 

use to calculate the national inventory for the amount of lead released to the air from the 

combustion of leaded avgas. Section 3 describes the landing and takeoff data we use to 

calculate airport-specific inventories for lead. Section 4 describes how we estimate 

landing and takeoff data for the airport facilities that do not report it to the FAA. 

Section 5 describes the estimate of landing and takeoff activity occurring at heliports in the 

U.S. Section 6 describes the methods used to calculate the airport-specific inventories for 

lead. Section 7 describes data that would be needed to improve the estimates of airportspecific inventories for lead and Section 8 describes the estimates of the amount of lead 

emitted in-flight that are in the 2008 NEI. 

In this document, units of tons (i.e., U.S. short tons) are used when discussing the 

national and airport-specific lead inventory in order to be consistent with the manner in 

which the NEI reports inventories for lead and other pollutants. The unit of grams is used 

in describing the concentration of lead in avgas and in describing emission factors. 

Conversion factors are provided for clarity. 

Section 2. Calculating the National Avgas Lead Inventory

Because lead is a persistent pollutant and accumulates in the environment, we 

include all lead emissions from piston-engine aircraft in the NEI – emissions occurring 

during the landing and take-off cycle at airports as well as emissions occurring at 

altitude.7 To calculate the national avgas lead inventory, we use information provided by 

the U.S. Department of Transportation’s (DOT’s) Federal Aviation Administration 

(FAA) regarding the volume of leaded avgas consumed in the U.S. in 2008.8 The U.S. 

Department of Energy’s (DOE’s) Energy Information Administration (EIA) provides 

information regarding the volume of leaded avgas produced in a given year. EPA has 

historically used the DOE EIA avgas fuel volume produced to calculate national lead 

inventories from the consumption of leaded avgas. However, since EPA uses DOT 

airport activity and aircraft data, we are using the DOT fuel volume data in the 2008 NEI 

to calculate the national lead inventory in order to use a consistent data source. In this 

document, when we refer to avgas fuel volume data it is data supplied by DOT, except 

where noted. 

As demonstrated in the equation below, to calculate the annual emission of lead 

from the consumption of leaded avgas, we multiply the volume of avgas used by the 

concentration of lead in the avgas, minus the small amount of lead that is retained in the 

engine, engine oil and/or exhaust system. The volume of avgas used in the U.S. in 2008

was 248,100,000 gallons.9

 The concentration of lead in avgas ([Pb] in the equation 

below) can be one of four levels (ranging from 0.14 to 1.12 grams of lead per liter) as 

specified by the American Society for Testing and Materials (ASTM). By far the most 

common avgas supplied is “100 Low Lead” or 100LL.10,11 The maximum lead 

concentration specified by ASTM for 100LL is 0.56 grams per liter or 2.12 grams per 

gallon.12 A fraction of lead is retained in the engine, engine oil and/or exhaust system 

which we currently estimate at 5%.13

For the 2008 NEI, the national estimate of lead emissions from the consumption 

of avgas was 551 tons (see equation below). 

(248,100,000 gal)(2.12 g Pb/gal)(0.95) = 551 tons Pb 

907,180 g/ton 

As described above, DOE’s EIA also provides estimates of the annual volume of 

leaded avgas produced in a given year. For 2008, the volume of avgas produced in the 

U.S. was 5,603 thousand barrels or 235,326,000 gallons.14 Consumption of this volume 

of avgas equates to a national lead emissions estimate for this source of 522 short tons. 

Section 3. Landing and Takeoff Data Sources and Uses

Airport-specific inventories require information regarding landing and takeoff 

(LTO) activity by aircraft type.15 According to FAA records, there are approximately 

20,000 airport facilities in the U.S., the vast majority of which are expected to have 

activity by piston-engine aircraft that operate on leaded avgas. Of these facilities, EPA’s 

NEI has in the past, reported emissions of lead (and other criteria pollutants and

hazardous air pollutants) at 3,410 airports.16 While the 3,410 airport facilities are among 

the most active in the U.S., they comprise only a small fraction of the total airport 

facilities where leaded avgas is used. 

FAA’s Office of Air Traffic provides a complete listing of operational airport 

facilities in the National Airspace System Resources (NASR) database. The electronic 

NASR data report, referred to here as the 5010 airport data report, can be generated from 

the NASR database and is available for download from the FAA website.17 This report is 

updated every 56 days. EPA obtains airport information (including operations) for a 

subset of the facilities in the NASR database from FAA’s Terminal Area Forecast (TAF) 

database that is prepared by FAA’s Office of Aviation Policy and Plans.18 The TAF 

database currently includes information for airports in FAA’s National Plan of Integrated 

Airport Systems (NPIAS), which identifies airports that are significant to national air 

transportation. Approximately 500 of the airports that are in the TAF database have 

either an FAA air traffic control tower or an FAA contract tower where controllers count 

operations. The operations data from the control towers is reported to The Operations 

Network (OPSNET)19 which is publically available in the Air Traffic Activity System 

(ATADS) database.20 The operations data for the towered airports that is reported in 

OPSNET and ATADS is then reported to the TAF database. The operations data for the 

airports in the TAF database that do not have control towers represent estimates.21 The 

operations supplied in the 5010 airport data report for facilities not reported in the TAF 

may be self-reported by airport operators through data collection accomplished by airport 

inspectors who work for the State Aviation Agency, or operations data can be obtained 

through other means.22

The 5010 airport data report supplies the date that the associated operations data 

represents.23 Because airports that are not in the TAF database submit data voluntarily to 

FAA for the 5010 data report, many of the airports have operations data that represent 

data for years earlier than 2008. Nationally, GA and AT piston-engine operations have 

decreased in recent years,24 therefore EPA did not use operations data from years prior to 

2008 as it is reported. Instead, EPA multiplied the older GA and AT piston-engine data 

(Section 6 describes the method EPA used to calculate the number of piston-engine 

16 These 3,410 facilities are the facilities for which the FAA’s Terminal Area Forecast (TAF) database 

provides information regarding aircraft activity. The TAF database is prepared by FAA’s Office of 

Aviation Policy and Plans and includes information for the airports in FAA’s National Plan of Integrated 

Airport Systems (NPIAS). One of the goals of the NPIAS is to identify airports that are significant to 

national air transportation.

operations from total GA and AT activity data) by scaling factors that were calculated by 

dividing the 2008 national amount of avgas produced by the national amount of avgas 

produced in the year the operations data represents.25 A table with the scaling factors is 

provided in Appendix A. The national volume of avgas produced data comes from the 

DOE, EIA website and is available for 1981 – 2009.26 For operations data older than 

1981, EPA divided the 2008 national amount of avgas produced by the average of the 

national amount of avgas produced from 1981 – 1989. Jet engines do not use avgas, 

therefore EPA did not apply scaling factors to the turbine operations for data from years 

prior to 2008. 

EPA also obtains operations data from the T-100 segment data from the Bureau of 

Transportation Statistics (BTS). The aircraft in the T-100 data are matched to aircraft in 

the FAA’s Emission and Dispersion Modeling System (EDMS) using the crosswalk table 

developed for earlier versions of the NEI. Generally the T-100 data covers commercial 

air carrier operations, but some AT activities are included in the data set that would 

double count with the TAF data at the same airport. To correct for possible double 

counting, first the AT LTOs included in the T-100 data were compiled using the aircraft 

type data included in the aircraft make/models crosswalk.27 The resulting aggregated 

LTOs were compared with the reported TAF LTOs for airports where there were 

overlaps. The T-100 AT LTOs were then subtracted from the TAF AT data to ensure 

that double counting was minimized. Note that if the T-100 AT value was larger than the 

TAF value, the TAF value was set to zero to eliminate the possibility of negative LTOs in 

the dataset. 

The 2008 draft NEI was developed using the January 15, 2009 version of the 

5010 airport data report. In that version of the report there were 19,925 airport facilities 

in the U.S. that had submitted data to the FAA. Among these 19,925 facilities, 99 

facilities were not relevant for the purposes of estimating lead emissions because they 

were either listed as closed (85) or they were balloonports (14).28 Therefore, lead 

inventories were needed for 19,826 facilities. In the January 15, 2009 version of the 5010 

airport data report there were 5,654 airport facilities for which operations data were 

provided (many of which are facilities in FAA’s TAF database).29 There were 14,172 

facilities in the 5010 airport data report for which there were no operations data.30 As a 

25 The FAA General Aviation and Air Taxi (Part 135) Activity Surveys (source of national level pistonengine operations data) are only available annually, starting in 1999. Because there are airports with 

operations data older than 1999, EPA used avgas product supplied data as a surrogate for piston-engine 

operations to estimate the change in piston-engine activity over the last three decades. 

26 http://tonto.eia.doe.gov/dnav/pet/hist/LeafHandler.ashx?n=PET&s=mgaupus1&f=A. DOT recently 

changed the way they estimate fuel consumption data, so while EPA used DOT data to determine the 2008 

national avgas lead inventory, for the purpose of calculating these scaling factors EPA used DOE’s data in 

order to have historical fuel data that is calculated in a consistent manner. 27 The T-100 data does not specify that the operations data is air taxi in nature; however, in discussions with 

FAA, EPA determined that these flights are air taxi in nature and has assigned them in the 2008 NEI as 

such.

B-6 

part of the review process for the draft 2008 NEI, EPA received updated airport data from 

states and also looked at more recent versions of the 5010 airport data report to update the 

status of airports, so the number of airports for which EPA estimated activity is slightly 

lower in the 2008 NEI than in the draft 2008 NEI. The following section of this 

document describes the method EPA used to estimate operations for the 14,132 airport 

facilities in the 2008 NEI that do not have reported activity data. 

As described in Section 1, most piston-engine aircraft fall into the categories of 

either GA or AT. Some GA and AT activity is conducted by turboprop and turbojet 

aircraft which do not used leaded avgas. There are no national databases that provide 

airport-specific LTO activity data for piston-engine aircraft separately from turbojet and 

turboprop aircraft. The databases described above report total GA and AT activity 

conducted by both piston-engine and jet-engine aircraft. Part (a) in Section 6 describes 

how we estimate piston-engine LTOs at airports in the 2008 NEI. 

Section 4. Estimating LTOs at the 14,132 Airport Facilities with No LTO Data

FAA has used regression models to estimate operations at facilities where 

operations data are not available.31,32 In this work and other work, FAA identified 

characteristics of small towered airports for which there were statistically significant 

relationships with operations at these airports.33 Regression models based on the airport 

characteristics were then used to estimate general aviation operations for a set of nontowered airports. The airport characteristics identified by FAA and used to estimate 

general aviation operations at small airports include: the number of aircraft based at a 

facility (termed ‘based aircraft’), population in the vicinity of the airport, airport regional 

prominence, per capita income, region, and the presence of certificated flight schools. 

In the 2000 report titled ‘Model for Estimating General Aviation Operations at 

Non-towered Airports,’ a model of GA annual activity was developed using information 

from small towered airports to explain GA activity at towered and non-towered airports. 

The model explained GA activity at the towered airports well (R2

 of 0.75) but produced 

higher estimates than state-supplied estimates for non-towered airports.34

The relevant data available in the 5010 airport data report for the purposes of 

estimating airport operations include: facility type (airport, balloonport, seaplane base, 

gliderport, heliport, stolport,35 ultralight); number of GA aircraft based at each airport by

operations data (air taxi, commercial, commuter, GA itinerant, GA local, military)36; and 

operations date (12-month ending date on which annual operations data is based). 

Census data was also merged with the 5010 airport data report to give population data for 

each airport’s county. 

Using the FAA work referenced above, we explored relationships among the 

airport data variables that best predicted aircraft activity (LTOs). We found that based 

aircraft was a highly significant and positive regressor to LTOs. Table 1 shows that for 

facilities that did not have LTO data in the January 15, 2009 version of the 5010 airport 

data report, 7,856 had based aircraft data while 6,316 did not have based aircraft data.37, 38 

Therefore, as described below, LTO estimates were derived using different methods 

depending on data availability.

not have LTO data and/or based aircraft data for airport facilities in the January 15, 2009

36 As explained in footnote 15, an aircraft operation is defined as any landing or takeoff event, therefore, to 

calculate LTOs, operations are divided by two. The 5010 airport data report from FAA reports aircraft 

activity in numbers of operations which, for the purposes of calculating Pb emissions using the method 

described in the TSD, are converted to LTO events. 

37 As described in Section 3, the number of facilities with no LTO data changed slightly from the draft 2008 

NEI to the 2008 NEI. In the 2008 NEI, of the facilities that did not have reported activity data, 7,837 

facilities reported based aircraft data and 6,295 did not report based aircraft data. 

38 These numbers include data for the following types of facilities: airports, balloonports, seaplane bases, 

gliderports, heliports, stolports, and ultralights.

(a) Estimating LTOs at Facilities with Based Aircraft Data, but No LTO Data: 

There are 6,414 facilities in the 2008 NEI (not including heliports) for which the 

5010 airport data report supplies the number of based aircraft39 but not activity data to 

which the regression equation (based aircraft vs. LTOs) could be applied. Using the 

4,872 airports for which both LTO and aircraft data is known, the initial relationship 

found between based aircraft and LTOs was: 

Equation 1: 

LTOs = 2494 + 208*aircraft R2 = 0.55

The FAA models found population to be another significant regressor. We used 

the population of the county in which the airport is located as the population variable. 

Adding county population to the model gave the following relationship: 

Equation 2: 

LTOs = 2204 + 194*aircraft + 0.0038*county population R2 = 0.56

EPA received numerous comments to the docket on its Advance Notice of 

Proposed Rulemaking on Lead Emissions from Piston-Engine Aircraft Using Leaded 

Aviation Gasoline40 indicating that aviation in Alaska is different than it is in the 

continental U.S. Commenters pointed out that in Alaska, 82% of communities are not 

accessible by road and rely on air transport for life sustaining goods and services.41

Commenters also noted that Alaskans travel by air eight times more often per capita than 

those in the continental U.S. For those reasons, we added a dummy variable in equation 

3 to identify whether or not an airport is located in Alaska. Because the relationship 

between based aircraft and LTOs is likely different for Alaskan airports than it is for 

airports that aren’t in Alaska, we also added an interaction term to equation 3 (interaction 

of an airport being in Alaska and its sum of based aircraft). 

Equation 3: 

LTOs = 1937 + 205*aircraft + 0.0038*county population + 566*Alaska –

108*(AlaskaXaircraft)

R2 = 0.58 

After analyzing the data and plot for the data underlying equation 3, we found 

many airport facilities identified as commercial airports for which based aircraft was 

extremely low (i.e., less than 10), yet LTOs were quite high (i.e., anywhere from 100,000 

39 Based aircraft for this purpose was limited to single- and multi-engine aircraft, helicopters, and 

ultralights since these aircraft types can use leaded avgas. 40 U.S. Environmental Protection Agency (2010) Advance Notice of Proposed Rulemaking on Lead

to more than 200,000 LTOs/year).42 These facilities were removed from the regression

analysis. Additionally, for reasons described below, heliports were also removed from

the regression. The resulting relationship was:

Equation 4: 

LTOs = 1293 + 203*aircraft + 0.0019*county population - 473*Alaska –

144*(AlaskaXaircraft) R2 = 0.65 

When equation 4 was applied to the 6,414 airport facilities that report based 

aircraft data but not LTO activity, the resulting sum of LTOs was almost 15 million. 

EPA estimates that the number of LTOs at the airports that do not report activity data 

should approximate the number of LTOs from the bottom of the distribution of the set of 

airports that report activity data to the 5010 airport data report but that are not in the TAF 

database. The average number of LTOs per year from airports in the bottom 30% of the 

set of airports that report activity data to the 5010 airport data report but that are not in 

the TAF database is ~63 LTOs/year. Multiplying 63 by the number of airports that do 

not report activity data equals 549,050 LTOs.43 Therefore, EPA used equation 4 to 

generate the distribution of LTOs at the individual airports that report based aircraft data 

but not activity data and then applied a scaling factor of 0.0356 to those LTOs to obtain 

the LTOs that are reported in the 2008 NEI.44 The sum of the LTOs from this set of 

airports plus the sum of the LTOs at the airports that do not report either based aircraft or 

activity data (described below in section (b)) sum to 549,050 LTOs. These LTOs are all 

assigned to the GA, piston-engine category since they are assigned to smaller general 

aviation airports that are assumed to have little to no air taxi or jet aircraft activity. 

Equation 4 and the scaling factor were used to estimate LTO activity for the 

2008 NEI at airport facilities that report based aircraft data but not activity data. 

(b) Estimating LTOs at Facilities with Neither Based-Aircraft Data nor LTO Data: 

There are 2,260 facilities (not including heliports) for which the 5010 airport data 

report supplies neither the number of based aircraft nor activity data. In the absence of 

data to establish a relationship to airport activity, we assign a default value of LTOs to 

the GA, piston-engine category for each of these facilities. 

42 From FAA’s website, “Addresses for Commercial Service Airports”, available at: 

http://www.faa.gov/airports_airtraffic/airports/planning_capacity/passenger_allcargo_stats/addresses/media 

/commercial_service_airports_addresses.xls 43 This rounded number is calculated by multiplying 63.298 LTOs/year by 8,674, which is the number of 

airports that don’t report activity data (6,414 don’t report activity data and 2,260 facilities don’t report 

activity or based aircraft data). 

44 The scaling factor was calculated by dividing 528,710 LTOs by 14,862,767 LTOS; the 528,710 LTOs are 

equal to 549,050 LTOs minus 20,340 LTOs (20,340 LTOs represent the sum of LTOs assigned to the 2,260 

facilities that don’t report either activity data or based aircraft data - the derivation of LTO estimates for 

these facilities is described in Section 4 (b)). The 14,862,767 LTOs are the sum of LTOs that result from 

applying equation 4 to the 6,414 facilities with based aircraft data but no activity data. 
B-10 

The default value was determined by evaluating GA LTOs that are reported at the 

set of 2,471 facilities that report activity data to the 5010 airport data report but that are 

not in the TAF set of airports. The average number of LTOs reported to the bottom ten 

percent of these facilities (when sorted by total GA LTOs) was 9. These facilities are 

assumed to most closely approximate the set of 2,260 facilities that do not report any 

based aircraft or LTO data; therefore, we assigned 9 LTOs to the GA, piston-engine 

category for these airport facilities for purposes of developing inventory estimates. 

Section 5. Calculating LTOs at Heliports:

There were 5,559 heliport facilities in the January 15, 2009 FAA 5010 data report 

that were operational. Of those, only 92 (or 2%) reported LTO data, and of those, only 

31 reported both based aircraft and LTO data. Because of the limited information 

regarding activity at heliports, some municipalities have hired contractors to survey 

activity in their local area.45, 46 

The summary statistics for LTO data provided at the 92 operational heliports is 

presented in Table 2. These facilities report a wide range in activity from 3 LTOs/year to 

more than 18,000 LTOs/year. Some facilities clearly have significant helicopter traffic 

(i.e., thousands of LTOs/year) which is supported by the contractor summaries of heliport 

activity in the Washington Metropolitan area. The little data available to us suggests that 

the median helicopter activity is less than 200 LTOs/year. In the absence of more 

information on which to base estimates of LTO activity, we assigned 141 LTOs (the 

median of the reported heliport LTOs) to the GA category at all of the heliports which do 

not report LTO data. The piston-engine fraction developed in Section 6 is applied to the 

141 LTOs resulting in 51 LTOs assigned to the GA, piston-engine category and 90 

assigned to the GA, turbine-engine category. This is an area of significant uncertainty in 

the inventory and one for which EPA is seeking information from local agencies.

Section 6. Methodology for Estimating Airport­Specific Lead Emissions

In 2008, EPA developed a method to calculate lead emissions at airports where 

piston-engine powered aircraft operate. 47 This method brings lead inventories into 

alignment with the manner in which other criteria pollutants emitted by aircraft are 

calculated. This method is described here with changes that were made from previous 

methods (i.e., the method used to develop the 2002 inventory) and applied in developing 

airport lead inventories for the 2008 NEI. In this section we first present the equation 

used to calculate lead emitted during the LTO cycle then we describe each of the 

components of the input data: we describe how we calculate piston-engine LTOs from 

data available in FAA databases, we describe the derivation of the emission factor for the 

amount of lead emitted during the LTO cycle, and we describe the estimate of the amount 

of lead retained in the engine and oil that we do not include in the amount of lead 

released to the air. 

Historically, where aircraft specific activity data are available (such as T-100), 

aircraft gaseous and particulate matter (PM) emissions have been calculated through the 

FAA’s EDMS.48 This modeling system was designed to develop emission inventories 

for the purpose of assessing potential air quality impacts of airport operations and 

proposed airport development projects. However, EDMS has a limited number of pistonengine aircraft in its aircraft data and is currently not set up to calculate metal emissions 

and thus, it is not a readily available tool for determining airport lead inventories related 

to aircraft operations. In developing this approach to determine piston-engine aircraft 

lead emissions, EPA relied upon the basic methodology employed in EDMS. This 

requires as input the activity of piston-engine aircraft at a facility, fuel consumption rates 

by these aircraft during the various modes of the LTO cycle and time in each mode 

(taxi/idle-out, takeoff, climb-out, approach, and taxi/idle-in), the concentration of lead in 

the fuel and the retention of lead in the engine and oil. The equation used to calculate 

airport-specific lead emissions during the LTO cycle is below, followed by a description 

of each of the input parameters. 

LTO Pb (tons) = (piston-engine LTO)(avgas Pb g/LTO)(1-Pb retention)

907,180 g/ton 

(a) Calculating Piston-engine LTO: 

Piston-engine LTOs are used to calculate emissions of lead that are assigned to 

the airport facility where the aircraft operations occur. An aircraft operation is defined as 

any landing or takeoff event, therefore, to calculate LTOs, operations are divided by two. 

Most data sources from FAA report aircraft activity in numbers of operations which, for 

the purposes of calculating lead emissions, need to be converted to LTO events. We

describe here the method used to estimate the fraction of GA and AT LTOs at an airport 

that are conducted by piston-engine aircraft. These fractions are calculated separately 

(one fraction for GA and one for AT). These fractions are multiplied by total LTOs 

reported separately for GA and AT and then summed to arrive at the total LTOs 

conducted by piston-engine aircraft at an airport. 

One use of the 2008 NEI is to identify sources of lead, including airports, that 

have inventories of 0.50 tons per year or more for the purposes of identifying locations 

where lead monitoring may be required to evaluate compliance with the National 

Ambient Air Quality Standard for Lead. To calculate the most airport-specific 

inventories for airports that may potentially exceed this inventory threshold, we used a 

more airport-specific surrogate for this subset of airports than the remainder of the 

airports where we applied national default averages described below. 

We used the fraction of based aircraft at an airport that are single- or multi-engine 

to calculate the number of GA LTOs at an airport that were conducted by piston-engine 

aircraft. The data regarding the population of based aircraft at an airport is available for a 

subset of airports in the FAA 5010 master records data report described in Section 3. For 

example, if an airport reports 150 single-engine aircraft, 20 multi-engine aircraft and a 

total of 180 aircraft based at that facility, then the fraction of based aircraft we would use 

as a surrogate for piston-engine aircraft is 94% ((150+20)/180). We then multiply the 

total GA LTOs for that facility by 0.94 to calculate piston-engine LTOs. 

We evaluated this surrogate by comparing the results of using it with pistonengine aircraft operations reported for airports that supply this information in master 

plans, airport layout plans, noise abatement studies and/or land use compatibility plans. 

We could rarely find data from the same year for comparison purposes; however, for the 

majority of airports, based aircraft and actual observed piston-engine aircraft activity 

agreed within ten percent.49

For the majority of airports in the 2008 NEI we used national average fractions of 

GA and AT LTOs conducted by piston-engine aircraft that were derived using FAA’s 

General Aviation and Part 13550 Activity Surveys – CY 2008 (GAATA).51 Table 2.4 in 

the 2008 GAATA Survey reports that approximately sixty-six percent (66%) of all GA 

and AT LTOs are from piston-engine aircraft which use avgas, and about thirty-four

percent (34%) are turboprop and turbojet powered which use jet fuel, such as Jet A. The 

LTO data in Table 2.4 in the 2008 GAATA Survey does not distinguish LTOs as GA or 

AT, and thus does not allow us derive separate piston activity fractions for GA and AT. 

We are using the number of hours flown by piston versus turboprop or turbojet 

aircraft (reported in Table 1.4 in the 2008 GAATA Survey) to allow us to make separate 

estimates of the fraction of GA activity conducted by piston aircraft and the fraction of 

AT activity conducted by piston aircraft. We chose to use the fraction of hours flown by 

piston-engine aircraft as a surrogate to calculate the fraction of LTOs flown by piston 

aircraft since the overall (i.e., for GA and AT combined) piston percent of hours flown 

(66.4%) is very close to the percent of LTOs that are piston (65.7%). Table 1.4 of the 

2008 GAATA presents the total hours flown by aircraft type and separates GA from AT. 

Seventy-three percent (73%) of all GA hours flown are by piston-engine aircraft while 

twenty-eight percent (28%) of all GA hours flown are by turboprop and turbojet powered 

aircraft.52 Twenty-three percent (23%) of all AT hours flown are by piston-engine 

aircraft while seventy-seven percent (77%) of all AT hours flown are by turboprop and 

turbojet powered aircraft. Approximately 5,000 of the total 20,000 airport facilities in the 

U.S. are heliports at which only helicopters (rotocraft) operate. Therefore, EPA also 

calculated the percent of rotocraft hours flown that are conducted by piston-engine 

aircraft. Thirty-six percent (36%) of all GA rotocraft hours flown are by piston-engine 

rotocraft while sixty-four percent (64%) of all GA rotocraft hours flown are by turboprop 

and turbojet powered rotocraft. Two percent (2%) of all AT rotocraft hours flown are by 

piston-engine rotocraft while ninety-eight percent (98%) of all AT rotocraft hours flown 

are by turboprop and turbojet powered rotocraft. Table 3 identifies the piston and turbine 

fractions that were used in the absence of airport-specific information to calculate pistonengine operations at airports and heliports in the 2008 NEI.

(b) Calculating the Piston-engine Aircraft Emission Factor: Grams of Lead Emitted per 

LTO: 

Piston-engine aircraft can have either one or two engines. EDMS version 5.0.2 

contains information on the amount of avgas used per LTO for some single and twinengine aircraft. The proportion of piston-engine LTOs conducted by single- versus twinengine aircraft was taken from the FAA’s GAATA Survey for 2008 (90% of LTOs are 

conducted by aircraft having one engine and 10% of LTOs by aircraft having two 

engines).53 Since twin-engine aircraft have higher fuel consumption rates than those with 

single engines, a weighted-average LTO fuel usage rate was calculated to apply to the 

population of piston-engine aircraft as a whole. For the single-engine aircraft, the 

average amount of fuel consumed per LTO was determined from the six types of single 

piston-engine aircraft within EDMS.54 This was calculated by averaging the singleengine EDMS outputs for fuel consumed per LTO using the EDMS scenario property of 

ICAO/USEPA Default - Times in Mode (TIM), with a 16 minute taxi-in/taxi-out time 

according to EPA’s Procedures for Emission Inventory Preparation, Volume IV: Mobile 

Sources, 1992.55 This gives a value of 16.96 pounds of fuel per LTO (lbs/LTO). The 

average single-engine fuel consumption rate was divided by the average density of 

100LL avgas, 6 pounds per gallon (lbs/gal), producing an average fuel usage rate for 

single-engine piston aircraft of 2.83 gallons per LTO (gal/LTO). This same calculation 

was performed for the two twin-engine piston aircraft within EDMS, producing an 

average LTO fuel usage rate for twin-engine piston aircraft of 9.12 gal/LTO. 

Using these single- and twin-engine piston aircraft fuel consumption rates, a 

weighted average fuel usage rate per LTO was computed by multiplying the average fuel 

usage rate for single-engine aircraft (2.83 gal/LTO) by the fleet percentage of singleengine aircraft LTOs (90%). Next, the twin-engine piston aircraft average fuel usage rate 

(9.12 gal/LTO) was multiplied by the fleet percentage of twin-engine aircraft LTOs 

(10%). By summing the results of the single- and twin-engine aircraft usage rates, the 

overall weighted-average fuel usage rate per LTO of 3.46 gal/LTO was obtained. 

To calculate the emission factor, the concentration of lead in fuel is multiplied by 

the fuel consumption per LTO. The maximum lead concentration specified by ASTM for 

100LL is 0.56 grams per liter or 2.12 grams per gallon. This amount of lead is normally 

added to assure that the required lean and rich mixture knock values are achieved. 

Multiplying this lead concentration in avgas by the weighted average fuel usage rate 

produces an overall average value of 7.34 grams of lead per LTO (g Pb/LTO) for pistonengines: 3.46 gal/LTO x 2.12 g Pb/gal = 7.34 g Pb/LTO. 

53 The LTOs from the categories of 1-engine fixed wing piston, piston rotocraft, experimental total, and

light sport were summed to determine the total number of single-engine piston aircraft LTOs. 54 EPA understands that EDMS 5.0.2 has a limited list of piston-engines, but these are currently the best

data available.

81026d (Revised), 1992.
B-15 

(c) Retention of Lead in Engine and Oil (1-Pb Retention): 

Data collected from aircraft piston-engines operating on leaded avgas suggests 

that about 5% of the lead from the fuel is retained in the engine and engine oil.56 Thus 

the emitted fraction is 0.95. This information is used in calculating airport-specific lead 

inventories and will be used to develop future national estimates of lead emitted from the 

consumption of leaded avgas. 

Applying these parameters in the equation above yields the following equation: 

Pb(tons) = (piston-engine LTO) (7.34 g Pb/LTO) (0.95) 

907,180 g/ton 

which simplifies to: 

Pb(tons) = (piston-engine LTO) (7.7 X 10-6) 

Where piston-engine LTO57 = (GA LTO x 0.725) + (AT LTO x 0.231) 

(d) Estimating Lead Emissions from Piston-Engine Helicopters: 

The emission factor for helicopters (g Pb/LTO) was determined in the same 

manner as described above for piston-engine fixed-wing aircraft. The concentration of 

lead in avgas (2.12 g/gal) was multiplied by the weighted average fuel usage rate for four 

types of Robinson helicopter engines.58 This produced an overall average emission 

factor of 6.60 grams of lead per LTO (g Pb/LTO) for piston-engine powered helicopters. 

There are no national databases that provide heliport-specific LTO activity data 

for piston-engine powered helicopters separately from turbine-engine powered 

helicopters. The 2008 FAA GA and Part 135 Activity (GAATA) Survey reports that 

approximately 36% of all GA helicopter hours flown are by piston-engine aircraft which 

use avgas, and about 64% are by turbine-engine powered which use jet fuel (which does 

56 The information used to develop this estimate is from the following references: (a) Todd L. Petersen,

Aviation to Bryan Manning of U.S. EPA, regarding lead retained in engine, September 28, 2007. 57 This equation for piston-engine LTOs only applies to non-heliport facilities. See the text immediately 

below for equations for calculating piston-engine LTOs and Pb emissions at heliports. 58 This was done using the following 4 engine types in EDMS 5.1: Robinson R22 IO-320-D1AD; Robinson 

R22 IO-360-B; Robinson R22 O-320; Robinson R22 TSIO-360C. The fuel consumption rates were: 

Robinson R22 IO-320-D1AD – 5.546 g Pb/LTO; Robinson R22 IO-360-B – 5.973 g Pb/LTO; Robinson 

R22 O-320 – 6.276 g Pb/LTO; Robinson R22 TSIO-360C – 8.604 g Pb/LTO.

not contain lead).59 The 2008 FAA GAATA Survey reports that approximately 2% of all 

AT helicopter hours flown are by piston-engine aircraft which use avgas, and about 98% 

are by turbine-engine powered rotocraft. We expect the fraction of helicopter activity 

conducted by piston-engines to vary by heliport with some facilities having no pistonengine powered helicopter activity and some hosting mainly or only piston-engine 

powered helicopters. However, in the absence of heliport-specific data, the national 

default estimates of 36% for GA and 2% for AT from the GAATA Survey were used. 

Therefore, to calculate piston-engine aircraft LTO as input for this equation, the 

helicopter GA LTOs were multiplied by 0.36 and helicopter AT LTOs were multiplied by 

0.02. 

Lead emitted at the heliport facility was calculated for the 2008 NEI using either 

the LTO data provided in FAA databases or the estimate LTO activity in the following 

equation (i.e., 141 LTOs): 

Pb(tons) = (piston-engine helicopter LTO) (6.60 g Pb/LTO) (0.95)

907,180 g/ton 

which simplifies to: 

Pb(tons) = (piston-engine helicopter LTO) (6.9 X 10-6) 

Where piston-engine helicopter LTO = (Helicopter GA LTO x 0.36) + (Helicopter AT

LTO x 0.02) 

Section 7. Improving Airport­specific Lead Emissions Estimates

There are refinements to the methods described here that would improve airportspecific inventories, most of which involve acquiring airport- and aircraft-specific input 

data. The following information describes data inputs that could be used to generate 

airport lead inventories tailored to specific airports or otherwise improve the estimates 

using currently available data. State and local authorities might have, or be able to 

collect, better information for some of these key data inputs. 

State and local agencies might have access to airport-specific data that would 

improve the national estimates of lead emissions per LTO. These improvements largely 

involve replacing national average or default values with airport-specific data on the 

activity of piston-engine aircraft. Three key data inputs are: 

59 The FAA GAATA is a database collected from surveys of pilots flying aircraft used for general aviation 

and air taxi activity. For more information on the GAATA, see Appendix A at 

http://www.faa.gov/data_statistics/aviation_data_statistics/general_aviation/
B-17 

1) Airport-specific LTO activity for piston-powered aircraft, including the fraction 

of piston-engine activity conducted by single- versus twin-engine aircraft. Some 

airport facilities collect this information and states may use these data to 

calculate airport-specific lead inventories. The activity data should be current 

and updated on a regular schedule so that the data represents the inventory year 

as closely as possible. 

2) The time spent in each mode of the LTO cycle. EPA uses the EDMS scenario 

property of ICAO/USEPA Default - Times in Mode, with a 16 minute taxiin/taxi-out time according to EPA’s Procedures for Emission Inventory 

Preparation, Volume IV: Mobile Sources, 1992. While some local authorities 

have confirmed that these are the relevant times in mode at their airports for 

piston aircraft, the applicability of these times in mode will vary by airport. EPA 

has learned that one of the important factors in piston aircraft operation that is 

currently not included in the time in mode or emissions estimates is the time and 

fuel consumption during the pre-flight run-up checks conducted by piston-engine 

aircraft prior to takeoff. 

3) Other data inputs for the airport-specific lead inventory calculation for which 

states or local authorities may provide airport-specific information include the 

concentration of lead in the avgas supplied at an airport, and the fraction of lead 

in fuel that is retained in the engine and oil, and aircraft-specific fuel 

consumption rates by the piston-engine aircraft in specific modes of operation. 

The accuracy of the based aircraft data on which equation 4 is modeled can be 

improved. FAA recognizes the need to improve the integrity of the 5010 data report 

based-aircraft counts for all of the GA airports and reliever airports in the NPIAS and is 

currently in the process of improving the data collection and submission methods to 

accomplish this task.60

Section 8. Lead emitted in flight (i.e., outside the LTO cycle):

Lead emissions, especially those at altitude, undergo dispersion and eventually 

deposit to surfaces, and lead deposited to soil and water can remain available for uptake 

by plants, animals and humans for long periods of time. Because lead is a persistent 

pollutant, we are including all lead emissions – at airports and in-flight – in the NEI.61

For inventory purposes, lead emitted outside the LTO cycle occurs during aircraft 

cruise mode and portions of the climb-out and approach modes above the mixing height 

(typically 3,000 ft62 ). This part of an aircraft operation emits lead at various altitudes as 

well as close to and away from airports. Because the precise area of lead emission and 

deposition is not known for these flights, EPA is using a simplistic approach to allocate

Office, Washington, DC, October, 2006.

these emissions for the purposes of the 2008 NEI. A brief explanation of the nature of 

GA flights is provided here for context regarding emissions of lead in-flight. 

FAA categorizes GA flights as either local area or itinerant operations and this 

distinction plays a role in the area over which lead is emitted. Local operations are those 

activities performed by aircraft operating in the local traffic pattern or within sight of the 

airport, aircraft executing simulated instrument approaches or low passes at the airport, 

and/or aircraft operating to or from the airport in a designated practice area located 

within a 20-mile radius of the airport. Local operations are common for GA aircraft. 

This includes applications such as recreational, proficiency and instructional flying as well 

as many common general aerial support tasks. Emissions during local flying are more 

likely to influence air and soil concentrations of lead in the vicinity of the airport because 

they occur near the airport, often at altitudes below the mixing height. 

Itinerant operations are all operations other than those described above as local 

operations. An itinerant aircraft operation usually is one in which the aircraft departs 

from one airport and lands at a different airport. Depending on air time and distance, an 

itinerant flight is much more likely to involve departing the local flying area of the 

originating airport and climbing to altitudes above the mixing height. It is reasonable 

then, to generally expect that lead emitted outside the LTO cycle during itinerant 

operations, in contrast with local operations, will be more widely dispersed and at greater 

distances from the airport. 

The portion of the national avgas lead emitted in flight (i.e., outside the LTO 

cycle) is calculated by subtracting the sum of airport facility lead inventories from the 

national avgas lead inventory. Even though FAA collects and reports information 

regarding the fraction of GA operations that are local and itinerant, there is no practical 

method to assign in-flight lead emissions to small geographic areas such as airports or 

census tracts. And similar data is not available for AT operations, a portion of which are 

conducted by piston-engine aircraft. Since the average duration of a piston-engine 

aircraft flight is approximately an hour, an itinerant flight can traverse county lines. 

Therefore, given the current data available, the best approach is to assign the out-of-LTO 

cycle lead to the state where the flight originated. 

In the 2008 NEI EPA allocated lead emissions that are calculated as being outside 

the LTO cycle to states based on the state-specific fraction of national GA and AT pistonengine LTO activity. The state-specific fractions were calculated by multiplying the 

percent of GA and AT piston-engine LTO activity in each state by 296 tons, which is the 

amount of lead we currently estimate is emitted outside of the LTO cycle nationwide. 

Table 4 presents the total GA and AT piston-engine LTOs by state, the state-specific 

faction of national GA and AT piston-engine LTO activity, and the out-of-LTO lead 

emissions assigned to each state.

1.0 INTRODUCTION 

1.1 What is the National Emission Inventory? 

The National Emission Inventory (NEI) is a comprehensive inventory covering all 

anthropogenic sources of criteria pollutants and hazardous air pollutants (HAPs) for all areas of 

the United States. The NEI was created by the U.S. Environmental Protection Agency’s 

Emission Inventory and Analysis Group (EIAG) in Research Triangle Park, North Carolina. The 

NEI will be used to support air quality modeling and other activities. To this end, the EPA 

established a goal to compile comprehensive emissions data in the NEI for criteria and HAPs for 

mobile, point, and nonpoint sources. This report presents an overview of how emission estimates 

for the commercial marine vessel (CMV) component of the 2008 NEI was compiled. 

1.2 Why Did the EPA Create the NEI? 

The Clean Air Act (CAA), as amended in 1990, includes mandates for the EPA related to 

criteria and hazardous air pollutants. The CAA defines criteria pollutants as being one of the 

following air pollutants: 

• Carbon monoxide (CO); 

• Sulfur oxides (SOx); 

• Nitrogen oxides (NOx); 

• Ozone; and 

• Particulate matter (PM). 

 Where emission factors and activity data permit, ammonia (NH3) estimates are also 

included as an important precursor to PM. Hazardous air pollutants are also delineated in the 

CAA, see http://www.epa.gov/ttn/atw/188polls.html for a complete list of regulated pollutants 

and their chemical abstract service [CAS] numbers. 

 The CAA requires the EPA to identify emission sources of these pollutants, quantify 

emissions, develop regulations for the identified source categories, and assess the public health 

and environmental impacts after the regulations are put into effect. The NEI is a tool that EPA 

can use to meet the CAA mandates. In this report, criteria and HAP emission estimates are 

discussed for CMV sources. 

1.3 How is the EPA Going to Use This Version of the NEI? 

 It is anticipated that the emission inventory developed from this effort will have multiple 

end uses. The data have been formatted according to protocols established for the EPA’s NEI 

submittals. The common data structure on which the NEI platform is based will allow the NEI 

emission data to be transferred to multiple end-users for a variety of purposes. 

1-1 
The criteria and HAP emission estimates developed for the NEI will be used to evaluate 

air pollution trends, air quality modeling analysis and impacts of potential regulations. 

1.4 Report Organization 

 Following this introduction, Section 2.0 provides information on how the national CMV, 

emission estimates were developed. This inventory effort was coordinated by the EPA’s Office 

of Transportation and Air Quality (OTAQ) and EIAG. 

 The appendix were created to provide technical details on how the national emissions 

were developed and how state and local inventory data (when provided) were incorporated into 

the national estimates. Appendix A provides a copy of the report documenting how the 2002 data 

were adjusted to reflect marine vessel activity and emissions for 2008.

2.0 DEVELOPMENT OF THE COMMERCIAL MARINE VESSEL 

COMPONENT FOR THE NEI 

2.1 How Does This CMV Study Fit into the NEI? 

The NEI was developed to include all point, nonpoint (sometimes referenced as “area”), 

and mobile sources. The approaches used in the point and nonpoint source categories are 

documented in other reports. Table 1 summarizes the approaches used to estimate emissions 

from all nonroad sources included in the NEI program. Those source categories and years that 

are included in this report are noted in bold. 

 The scope of this inventory component of the NEI was to compile criteria and HAP 

emissions data for CMVs operating in United States waters and federal waters extending 200 

nautical miles from the United States’ coastline. In this effort, national emission estimates were 

often developed and allocated to counties based on available Geographic Information System 

(GIS) data. The methodologies used to estimate emissions and the procedures used to spatially 

allocate them to the county-level are discussed in this report.

provided alternate nonroad inputs, these data 

replaced EPA default inputs. State-supplied 

emissions data also replaced default EPA 

emission estimates.

Using emission estimates from two emission 

inventories including: 1) a 1996 county-level 

inventory, developed using EPA’s October 

2001 draft NONROAD model; and 2) an 

updated 1999 national inventory, based on 

EPA’s draft Lockdown C NONROAD model 

(dated May 2002). Using the 1996 county-level 

emission estimates, seasonal and daily countyto-national ratios were then developed for 

application to updated national estimates per 

season estimated from the Lockdown C model. 

Replaced State-submitted data for California for 

all NONROAD model categories; Pennsylvania 

for recreational marine and aircraft ground 

support equipment, and Texas for select 

equipment categories.

year-specific national and California 

inventories, based on EPA’s draft Lockdown C 

NONROAD model (dated May 2002). Using 

the 1996 county-level emission estimates, 

seasonal and daily county-to-national ratios and 

California county-to-state ratios were then 

developed for application to updated national 

estimates per season estimated from the 

Lockdown C model. California results replace 

the diesel equipment emissions generated from 

prior application of county-to-national ratios.

2-9 
 The target inventory area includes every state in the United States and every county 

within a state. There are no boundary limitations pertaining to traditional criteria pollutant 

nonattainment areas or to designated urban areas. The pollutants inventoried included all criteria 

pollutants (except for the other nonroad source category which addressed only HAPs in this 

report) and the 188 HAPs identified in Section 112(b) of the CAA. Some state or local agencies 

provided emissions information on more HAPs than those delineated in the CAA, only the 

federally regulated HAPs are included in the NEI. 

 In addition to numerous specific chemical compounds, the list of 188 HAPs includes 

several compound groups [e.g., individual metals and their compounds, polycyclic organic 

matter (POM)]; the NEI includes emission estimates for the individual compounds wherever 

possible. Many of the uses of the NEI depend upon data (e.g., toxicity) for individual compounds 

within these groups rather than aggregated data on each group as a whole. 

 The intent in presenting the following emission inventory approach is to provide 

sufficient and transparent documentation such that states and local agencies can use these 

approaches, in conjunction with their specific local activity data to develop more accurate and 

comparable emission estimates in future submittals. 

2.2 What are Commercial Marine Vessels? 

 The CMV source category includes all boats and ships used either directly or indirectly in 

the conduct of commerce or military activity. These vessels range from 20-foot charter boats to 

large tankers which can exceed 1,000 feet in length (EPA, 1989). In spite of the broad range of 

vessels represented by this category, a number of common characteristics allow for the use of 

simple emission estimation methods. The majority of vessels in this category are powered by 

diesel engines that are either fueled with distillate or residual fuel oil blends. For the purpose of 

this inventory it is assumed that Category 3 vessels primarily use residual blends while Category 

1 and 2 vessels typically used distillate fuels. 

The Category 3 (C3) inventory developed by OTAQ includes vessels which use C3 

engines for propulsion. C3 engines are defined as having displacement above 30 liters per 

cylinder (U.S. EPA, 2003). The resulting inventory includes emissions from both propulsion and 

auxiliary engines used on these vessels, as well as those on gas and steam turbine vessels. 

Geographically, the inventories include port and interport emissions that occur within the area 

that extends 200 nautical miles (nm) from the official U.S. baseline, which is roughly equivalent 

to the border of the U.S. Exclusive Economic Zone (EEZ). 

Category 1 and 2 vessels tend to be smaller ships that operate closer to shore, and along 

inland and intercoastal waterways. Naval vessels are not included in this inventory, though Coast 

Guard vessels are included as Category 1 and 2 vessels. 

 The CMV source category does not include recreational marine vessels, which are 

generally less than 100 feet in length, most being less than 30 feet, and powered by either 

inboard or outboard engines (EPA, 1989). Emissions from recreational marine vessels are 

included in the nonroad source category. 

2-10 
2.3 What Pollutants are Included in the National Emission Estimates for CMVs? 

 The EPA’s Office of Transportation and Air Quality (OTAQ) provided estimates for all 

criteria pollutants including volatile organic compounds (VOC), nitrogen oxides (NOx), carbon 

monoxide (CO), sulfur oxides (SOx), particulate matter less than 10 microns (PM10), particulate 

matter less than 2.5 microns (PM2.5) and carbon dioxide (CO2). Criteria emissions were provided 

for Category 1 and 2 vessels (Carey, 2009b); Category 3 port, reduced speed zone, and cruising 

activities (Carey, 2009a and Carey, 2009c); and Category 3 interport activities (Carey, 2009d). 

The VOC and PM estimates were speciated into hazardous air pollutants (HAP) 

components based on available data sources. The Swedish Environmental Protection Agency 

(SEPA) document Methodology for Calculating Emissions from Ships: 1. Update of emission 

factors served as the primary source of HAP emission factors which were converted into 

speciation profiles (Cooper and Gustafsson, 2004). Ammonia emission factors were also 

obtained from the SEPA, but as these factors require activity data, and such data were not 

available for Category 3 vessels operating in Federal waters, ammonia was estimated as a ratio of 

PM10 using the SEPA emission factors. Similar ratios were developed for Category 1 and 2 

vessels, assuming that this fleet primarily operates on marine diesel fuel with 80.5 percent of the 

fleet equipped with medium speed engines and the remaining 19.5 percent were high speed 

engines. This provided a weighted NH3 emission factor of 4.61E-03 g/kw-hr for operations atsea and in-port. The PM10 factors vary for at-sea (0.2 g/kw-hr) and in-port (0.4 g/kw-hr), so our 

NH3 / PM10 ratios were different for at-sea (2.31E-02) and in-port (1.15E-02). 

 While the SEPA document was used as the primary speciation source, other resources 

were investigated for potential inclusion in this effort. Recent BTEX data from Moldanova et al. 

were examined, but it included inconsistent benzene factors, some over 20% of hydrocarbon 

(HC) factors, were much higher than others found in recent publications and, as a result, were 

not included (Cook, 2009). CE-CERT metals data was also reviewed as it pertained to slow 

speed residual fuel engines (Cook, 2009). The CE-CERT emission factors were in line with the 

Swedish factors for nickel and lead, but they were an order of magnitude different for chromium, 

cadmium, and selenium. As a result, the Swedish factors were retained over the CE-CERT data 

based on the larger study sample size, while CE-CERT’s manganese emission factors were 

added as these factors were not included in the Swedish study (Cook, 2009). 

The complete pollutant list for CMVs is shown in Table 2-2. 

2.4 How Were the CMV Emissions Estimated? 

As noted above, the CMV criteria and CO2 emission estimates were provided for this 

inventory by OTAQ. Category 3 commercial marine inventories were developed for a base year 

of 2002 then projected to 2008 applying regional adjustment factors to account for growth. In 

addition, NOX adjustment factors were applied to account for implementation of the NOX Tier 1 

standard. Details about adjustments and growth factors can be found in the Category 3 

documentation (Appendix A). For Category 1 and 2 marine diesel engines, the emission 

estimates were consistent with the 2008 Locomotive and Marine federal rule making (Carey, 

2009b).

+ PM2.5 was provided by OTAQ for all vessels and modes except for Category 3 Interport, where it was calculated 

using OTAQ guidance. 

OTAQ’s emissions were then allocated to individual GIS polygons using appropriate 

methods that varied by operating mode (i.e., hotelling, maneuvering, reduced speed zone, and 

underway). HAP emissions were estimated by applying speciation profiles to each polygon’s 

VOC and PM estimates. Figure 2-1 provides an overview of the approach used to estimate and 

spatially allocate CMV emissions. 

Speciation profiles were applied to the VOC, PM10, and PM2.5 emission estimates to 

calculate the associated HAP emissions using the following equation. 

VOC-PM10/2.5 * speciation profilei = HAP emission estimate: 

 Where: 

HAP emission estimate = HAP Emission estimate (tons/year)

 For Category I diesel-powered vessels, the speciation profiles were based on high-speed 

diesel vehicle (HSDV) factors obtained from information in the SEPA’s Methodology for 

Calculating Emissions from Ships: 1. Update of emission factors (Cooper and Gustafsson, 2004). 

For Category 2 diesel-powered vessels, the speciation profiles were developed from mediumspeed diesel vehicles (MSDV). Since emissions and activity data were provided as a combined 

value for all Category 1 and 2 vessels, the Category 1 and Category 2 emission factors were 

averaged to obtain a single emission factor for all diesel vessels. All port activities for Category 

1 and 2 vessels were assumed to be maneuvering. 

 For Category 3 vessels, speciation profiles were developed using data from Methodology 

for Calculating Emissions from Ships: 1. Update of emission factors and assuming 80.5% of 

Category 3 vessels were equipped with slow-speed engines and 19.5% of vessels were equipped 

with medium speed engines based on vessel census data reported in the International Maritime 

Organization’s (IMO) recent greenhouse gas (GHG) study (IMO 2009). Separate speciation 

profiles were created for Category 3 vessels for underway, maneuvering, and hotelling activities. 

Chromium emissions were split into hexavalent and trivalent chromium based on an assumption 

that 34% of total chromium was hexavalent and the remaining 66% was trivalent. 

2.5 How Were Emissions Allocated? 

 Previous emissions allocations were based on waterway length and port county 

assignment. In this effort, spatial accuracy was greatly enhanced via the creation of GIS 

polygons representing port and waterway boundaries. GIS polygons allowed the 

estimation/allocation of emissions to defined port, waterway, and coastal areas, leading to 

improved spatial resolution compared to 2002’s county-level emissions. Methodologies for both 

port and underway emissions are described in detail in the sections that follow. 

2.6 How Were Port Emissions Allocated? 

 Port boundaries were developed using a variety of resources to identify the most accurate 

port boundaries. First, GIS data or maps provided directly from the port were used. Next, maps 

or port descriptions from local port authorities, port districts, etc. were used in combination with 

existing GIS data to identify port boundaries. Finally, satellite imagery from tools such as 

Google Earth and street layers from StreetMap USA were used to delineate port areas. Emphasis 

was placed on mapping the 117 ports with Category 3 vessel activity using available shape files 

of the port area. The Port of Huntington was developed differently given its large extent and 

limited available map data. The state of West Virginia provided a revised file of US Army Corps 

of Engineers port terminals reported to be part of the Port of Huntington-Tristate area. A 200 

meter buffer of the water features near these port terminals was created to identify port area. 

 In all cases, polygons were created on land, bordering waterways and coastal areas, and 

were split by county boundary. Each polygon was identified by the port name and state and 

county FIPS in addition to a unique ShapeID. Smaller ports with Category 1 and 2 activities 

were mapped as small circles. Note that no Category 3 emissions were mapped to small circles. 

The final shapefile contained 159 ports and 196 polygons. 

 OTAQ provided Category 1 and 2 criteria emissions and activity as a single national 

number. These emissions and activity were allocated to ports based on total commodity tonnage 

2-14 
data obtained from the U.S. Army Corps of Engineers (USACE) Principal Ports file for 2007 

(U.S. ACE, 2009). Emissions were then assigned to polygons within a port based on port area. 

 OTAQ developed port-level emissions for 117 of the largest U.S. ports with Category 3 

activity. Activity in megawatt hours (MWh) and resulting criteria and CO2 emissions were 

provided by port for maneuvering and hotelling modes. Emissions were then assigned to 

polygons within a port based on port area. HAP emissions were then speciated from VOC and 

PM estimates for each polygon using the methodology described in Section 3.0. 

2.7 How Were Underway Emissions Allocated? 

 For this inventory, a GIS polygon layer was created to more accurately represent the 

location of CMV-related activity and emissions. Inland waterway polygons were obtained from 

the Bureau of Transportation Statistics’ National Transportation Atlas Database hydro polygon 

layer (U.S. DOT, 2007). These polygons were further divided by county boundary and waterway 

ID. Coastal waters were drawn using Mineral Management Service state-federal boundary files 

and were also divided to indicate county boundaries. Federal waters were included as large area 

blocks outlined by the Exclusive Economic Zone (EEZ) boundary provided by EPA, which 

extends to approximately 200 nautical miles from the coastline. The final product is a polygon 

layer that includes all inland and coastal state waters and federal waters along with FIP, polygon 

area, and a unique ShapeID. Underway emissions were allocated differently by vessel category 

and mode, as outlined below. 

2.7.1 Category 1 and 2 Underway 

 OTAQ provided Category 1 and 2 criteria emissions and activity as a single national 

number. These emissions and activity were allocated to underway polygons in state waters based 

on total commodity movements (in tons) data obtained from USACE (U.S. ACE, 2001). These 

data were waterway-specific, so waterways that crossed into multiple FIPs had emissions 

assigned by waterway length in each polygon. HAP emissions were then speciated from VOC 

and PM estimates using the methodology described in Section 3.0 for each polygon. 

2.7.2 Category 3 Reduced Speed Zones (RSZ) 

 OTAQ provided polyline shapefiles indicating location of RSZ activities along with portspecific RSZ emissions and activity. These polylines were intersected with existing shipping lane 

polygons, and emissions were allocated to polygons based on the approach segment length on a 

per-port basis. HAP emissions were then speciated from VOC and PM estimates using the 

methodology described in Section 3.0 for each polygon. 

2.7.3 Category 3 Approach 

 OTAQ provided polyline shapefiles indicating location of cruising activities along with 

port-specific cruising emissions and activity. These polylines were intersected with our existing 

polygons, and emissions were allocated to polygons based on the approach segment length on a 

per-port basis. HAP emissions were then speciated from VOC and PM estimates using the 

methodology described in Section 3.0 for each polygon. 

2-15 
2.7.4 Category 3 Interport 

 OTAQ provided 4km grids for interport-only emissions for CO, CO2, HC, NOx, SOx, and 

PM10. These grids were provided in a customized projection which, without a custom geographic 

transformation, could not be converted to match the polygon layer’s projection. Furthermore, the 

emission estimates provided by OTAQ were developed using EEZs which were in the GCS Arc 

Sphere projection. Per OTAQ’s direction, the interport polygons were converted from North 

American Equidistant Conic to GCS Arc Sphere by using the data frame projections tool as the a 

transformation method. This approach was recommended by OTAQ in order to mirror previous 

methodology and provide emission estimates consistent with the recent Category 3 Commercial 

Marine Inventory. Zonal statistics tools were used to sum the gridded emissions within each 

underway polygon. HAP emissions were then speciated from VOC and PM estimates using the 

methodology described in Section 3.0 for each polygon. 

2.8 QA/QC 

 Given the significant methodological changes over previous inventory efforts, several 

quality checks were implemented to ensure that these data were developed and allocated in a 

clear and reproducible manner. Some of the quality checks implemented include the following: 

GIS shapefiles 

• Topology was created and validated through several rounds or revisions to remove 

gaps or overlapping features both within and between polygon layers. 

• Boundaries derived from Google Earth imagery were validated against Street Map 

network, port-provided map images, USACE ports points, and other online mapping 

resources to improve boundary accuracy. 

• All final shapefiles and polygon characteristics (such as area, etc.) were managed and 

evaluated in a single projection to ensure quality area and distance measurements, 

consistent results across CMV activity types, and maximum accuracy across the study 

area. The only exception to this was in the case of the interport criteria emissions, as 

described in Section 4.2.4. 

Emissions allocations and estimations 

• Emission factors were compiled from a variety of sources, and emission factor 

development methodologies evaluated to identify the most accurate emission factor 

for use in this inventory effort. 

• National emission sums were checked both before and after allocation to ensure no 

emissions were dropped or grown. 

• HAP speciation profiles were checked for accuracy, and speciated emissions were 

checked on both the polygon and national level to ensure accuracy. 

• All unit conversions were double-checked for errors. 

• Emission sums were evaluated across activity types (i.e., hotelling, maneuvering, 

cruising, reduced speed zones, and interport) to ensure they consistently mirror 

activity levels. 

• Port and underway emissions were examined across SCCs to ensure consistency with 

activity levels and vessel populations. 

2-16 
• 2008 pollutants and emissions were checked against the 2005 inventory to identify 

any missing pollutants or major changes compared to previous inventories. 

Discrepancies were investigated and revisions were made as needed. 

2.9 What are the Results? 

 Table 2-3 summarizes the emission estimates for CMVs for criteria pollutants. Table 2-4 

summarizes the emission estimates for individual HAPs. Note that for the purposes of this 

inventory vessels equipped with category 1 and 2 propulsion engines are assumed to operate on 

Distillate diesel, while vessels equipped with Category 3 propulsion engines are assumed to used 

a residual blend. Both tables provide data for all states; these 2008 estimates do not include state 

submitted data.

Commercial Marine Inventory. Office of Transportation and Air Quality, Ann Arbor, MI. 2009. 
Development of 2008CY Category 3 Commercial Marine Inventory 

 The Category 3 (C3) inventory includes vessels which use C3 engines for propulsion. C3 

engines are defined as having displacement above 30 liters per cylinder. The resulting inventory 

includes emissions from both propulsion and auxiliary engines used on these vessels, as well as 

those on gas and steam turbine vessels. 

 Geographically, the inventories include port and interport emissions that occur within the 

area that extends 200 nautical miles (nm) from the official U.S. baseline, which is roughly 

equivalent to the border of the U.S. Exclusive Economic Zone (EEZ). The U.S. region was 

clipped to the boundaries of the U.S. EEZ in areas where the 200nm boundary extended beyond 

the EEZ. 

 Category 3 commercial marine inventories were developed for a base year of 2002. [1] 

These were then projected to 2008. Regional adjustment factors were applied to account for 

growth. In addition, NOX adjustment factors were applied to account for implementation of the 

NOX Tier 1 standard. The methodology for each type of adjustment is described below. 

Growth Factors by Geographic Region

 The emissions inventory is calculated for nine geographic regions: Alaska East, Alaska 

West, East Coast, Gulf Coast, Hawaii East, Hawaii West, North Pacific, South Pacific, and the 

Great Lakes. Average annual growth rates from 2002-2020 were calculated for five regions: East 

Coast, Gulf Coast, North Pacific, South Pacific, and the Great Lakes. The Alaska regions were 

assigned the growth factor for the North Pacific region, while the Hawaii regions were assigned 

the growth factor for the South Pacific region. Each regional growth rate was then compounded 

over the inventory projection time period for 2008 (i.e., 6 years). The average annual growth 

rates and resulting multiplicative growth factors for each emission inventory region is presented 

in Table 1 below.

NOx Adjustment Factors

 The 2008 calendar year baseline inventory includes pre-control (Tier 0) engines and those 

subject to the NOX Tier 1 standard that became effective in 2000. The NOX emission factors 

(EFs) by tier and engine/ship type are given in Table 2.

Gas Turbine 6.1 n/a 

Auxiliary 

Passenger Ship 14.6 13.0 

Other Ships 14.5 12.9 

 The NOX EFs by tier were then used with age distributions to generate calendar year NOX

EFs by engine/ship type for 2008. For 2002, Tier 0 EFs were used for simplicity. These calendar 

year NOX EFs are provided in Table 3. Since the age distributions are different for vessels in the 

Great Lakes, NOX EFs were determined separately for the Great Lakes.

 Emission adjustment factors for NOX were then calculated. Adjustment factors are ratios 

of the 2008 calendar year EFs to the 2002 calendar year EFs. The adjustment factors by 

engine/ship type are provided in Table 4.

Methodology for Development of 2008CY Port Inventories

 For the non-California ports, 2002 emissions for each port are summed by engine/ship 

type. Propulsion and auxiliary emissions are summed separately, since the EF adjustment factors 

differ. The appropriate regional growth factor, as provided in Table 1, is then applied, along with 

the NOX EF adjustment factors by engine/ship type in Table 4 to calculate the 2008 port 

inventories. 

 For the California ports, 2002 emissions for each port are summed by ship type. 

Propulsion and auxiliary emissions are summed separately, since the EF adjustment factors 

differ. The EF adjustment factors by engine/ship type in Table 4 are consolidated by ship type, 

using the CARB assumption that engines on all ships except passenger ships are 95 percent slow 

speed diesel (SSD) engines and 5 percent medium speed diesel engines (MSD) based upon a 

2005 CARB survey. All passenger ships were assumed to be MSD engines. Steam turbines (ST) 

and gas turbines (GT) are not included in the CARB inventory. The NOX EF adjustment factors 

by ship type are then applied, along with ship-specific growth factors used by CARB, to 

calculate the 2008 California port inventories. The ship-specific growth factors for 2008 relative 

to 2002 are provided in Table 5 below.

Methodology for Development of 2008CY Interport Inventories

 The interport portion of the inventory is not segregated by engine or ship type. As a 

result, regional NOX EF adjustment factors were developed based on the assumed mix of main 

(propulsion) engine types in each region. The mix of main engine types by region was developed 

using the ship call and power data and is presented in Table 6. Main engines are considered a 

good surrogate for interport emissions, since the majority of emissions while underway are due 

to the main engines. The NOX EF adjustment factors by main engine type in Table 4 were used 

together with the mix of main engine types by region in Table 6 to develop the regional 

adjustment factors. The resulting NOX EF regional adjustment factors are provided in Table 7. 

These NOX EF regional adjustment factors, together with the regional growth factors in Table 1, 

were applied to calculate the 2008 interport inventories.

1.0 INTRODUCTION 

1.1 What are Locomotive Sources? 

The locomotive source category includes railroad locomotives powered by diesel-electric 

engines. A diesel-electric locomotive uses 2-stroke or 4-stroke diesel engines and an alternator 

or a generator to produce the electricity required to power its traction motors. The locomotive 

source category does not include locomotives powered by electricity or steam. Emissions 

associated with the operation of electric locomotives would be included in the point source utility 

emission estimate. It is believed that the number of wood or coal driven steam locomotives is 

currently very small; therefore, these types of locomotives are not included in this inventory. 

The locomotive source category is further divided up into three categories: Class I line 

haul, Class II/III line haul, and Class I yard. The national rail estimates were developed by the 

Eastern Regional Technical Advisory Committee hereafter referenced as ERTAC Rail. This 

group is comprised of eastern states’ regulatory agencies in collaboration with the rail industry. 

ERTAC Rail developed emissions estimates based on fuel data obtained from the American 

Association of Railroads for each subcategory. California locomotive emission estimates were 

handled separately from the rest of the United States because of their use of low sulfur 

locomotive diesel fuels.

2.0 DEVELOPMENT OF THE LOCOMOTIVE COMPONENT FOR THE 

NEI 

2.1 What Pollutants are Included in the National Emission Estimates for Locomotives? 

 All of the criteria pollutants, VOC, CO, NOx, SOx, PM, and PM2.5, are included in the 

locomotive component of the NEI. OTAQ identified the HAPs for which data were available to 

develop inventory estimates (Scarbro, 2001). The hazardous air pollutants (HAPs), listed below, 

were identified based on available test data and accepted emission estimation procedures. 

Emission estimation methods have changed over the history of the NEI, as outlined briefly in 

Table 2-2 for nonroad sources.

Using emission estimates from two emission inventories including: 1) a 1996 county-level inventory, developed using EPA’s October 2001 draft NONROAD model; and 2) an updated 1999 national inventory, 

based on EPA’s draft Lockdown C NONROAD model (dated May 2002). Using the 1996 county-level emission estimates, seasonal and daily county-to-national ratios were then developed for application to updated national estimates per season estimated from the Lockdown C model. Replaced State-submitted data 

for California for all NONROAD model categories; Pennsylvania for recreational marine and aircraft ground support equipment, and Texas for select equipment categories.

Using the 1996 county-level emission estimates, seasonal and daily county-to-national ratios and California county-tostate ratios were then developed for application to updated national estimates per season estimated from the 

Lockdown C model. California results replace the diesel equipment emissions generated from prior application of county-to-national ratios.

3.0 HOW WERE LOCOMOTIVE EMISSIONS ESTIMATED? 

ERTAC Rail used confidential railroad-provided data to generate railroad-specific 

criteria emission estimates for line haul and rail yards at the rail segment and rail yard level, 

respectively. Appendices A-C provide more detail on how emissions were developed and 

includes critical data used in calculating these estimates. This section of the report describes the 

emission estimating methods used in general terms as well as the approach for reallocating the 

emissions to protect confidential data. The data and documentation provided with respect to 

ERTAC Rail’s emission estimates pertain to the version that was incorporated into the NEI and 

does not reflect recent revisions. 

3.1 Line Haul Criteria Emissions Estimates 

Criteria pollutant emissions were estimated by applying emission factors to the total 

amount of distillate fuel oil used by line haul locomotives. Fuel usage was obtained from 

publically available Class I Railroad Annual Reports (Form R-1). The R-1 reports are submitted 

to the Surface Transportation Board annually and include financial and operations data to be 

used in monitoring rail industry health and identifying changes that may affect national 

transportation policy. Additionally, each railroad provided fleet mix information that allowed 

ERTAC Rail to calculate railroad-specific emission factors. Weighted Emission Factors (EF) 

per pollutant for each gallon of fuel used (gm/gal or lbs/gal) were calculated for each Class I 

railroad fleet based on its fraction of line haul locomotives at each regulated Tier level. EPA 

emission factors were used for PM2.5, SO2, and NH3. 

The weighted emission factors were then applied to the link-specific fuel consumption to 

obtain emissions for each rail segment. Given the confidentiality of the activity data, emissions 

for criteria pollutants were provided to EPA by ERTAC Rail by county for Class I line haul. 

Class II/III rail was provided by railroad company and county. Appendices A and B provide 

more detail on the Class I and Class II/III line haul emission development, respectively. 

3.2 Rail Yard Criteria Emissions Estimates 

Rail yard locations were identified using a database from the Federal Railroad 

Administration. Criteria pollutant emissions were estimated by applying emission factors to the 

total amount of distillate fuel used by locomotives. Each railroad provided fleet mix information 

that allowed ERTAC to calculate railroad-specific emission factors. The company-specific, 

system wide fleet mix was used to calculate weighted average emissions factors for switchers 

operated by each Class I railroad. EPA emission factors were used for PM2.5, SO2, and NH3. 

R-1 report-derived fuel use was allocated to rail yards using an approximation of line 

haul activity data within the yard; see Appendix C for more details. These fuel consumption 

values were further revised by direct input from the Class I railroads. The weighted emission 

factors were then applied to the yard-specific fuel consumption to obtain emissions for each 

yard. Since the rail yard inventory was based on publically-available data, the final criteria 

emission estimates were provided per rail yard. 
3-2 

3.3 Hazardous Air Pollutant Emissions Estimates 

HAP emissions were estimated by applying speciation profiles to the VOC or PM 

estimates. The speciation profiles were derived from Evaluation of Factors that Affect Diesel 

Exhaust Toxicity (Truex and Norbeck, 1998), and data provided by OTAQ (Scarbro, 2001 and 

2002). It should be noted that since California uses low sulfur diesel fuel and emission factors 

specific for California railroad fuels were available, calculations of the state’s emissions were 

done separately from the other states. The HAP speciation profile used in this effort is shown in 

Table 3-1. HAP estimates were calculated at the yard and link level, after the criteria emissions 

had been allocated.

4.0 HOW WERE COUNTY LINE HAUL EMISSIONS REALLOCATED 

TO INDIVIDUAL RAIL SEGMENTS? 

4.1 Class I Line Haul Emissions Allocation 

Class I line haul emissions were allocated to rail segments based on segment-specific 

railroad traffic data (ton miles) obtained from the Department of Transportation (BTS, 2009). 

This dataset categorizes the segments’ level of activity into ranges of MGTM and is populated 

by FRA. Emissions were divided between all mainline segments using these activity ranges as a 

proxy to allocate more emissions to segments with higher activity. 

Since the activity data were provided as ranges, a single “allocation value”, typically the 

midpoint of the range, was selected for use in the emissions allocation. The exception to this 

was the “0” activity category, which by definition had “unknown” activity. As a result, most 

mainline segments with the “0” activity category were not included in the emissions 

calculation/allocation. However, there was a small subset of segments that did have known 

activity values in the confidential data set but were labeled as “unknown” in the publically 

available data set. Those segment IDs were provided by ERTAC Rail for inclusion in the 

emission allocation; however, the activity of these segments was averaged to protect confidential 

data. Table 4-1 lists the activity categories along with their ranges in MGTM/mi and the 

allocation value used in the emissions spatial allocation.

* The “0” category has “unknown” activity in the publically 

available segment data. As a result, this table lists the minimum, 

maximum, and average of the confidential activity data greater 

than zero that were categorized as “unknown” in the public data. 

The county emission sums were reallocated to the segments by multiplying the county 

emissions by the segment’s allocation value divided by the sum of the allocation values for all 

links within the county.

ALC = Sum of allocation values for all links in county C from public BTS dataset 

 Note that rail line data for Puerto Rico, U.S. Virgin Islands, and Hawaii data were not 

included in ERTAC Rail’s shapefile and were developed separately; however, since these areas 

have exclusively Class II/III railroads present, these efforts are discussed in the following 

section. 

4.2 Class II/III Line Haul Emissions Allocation 

ERTAC Rail created a shapefile of Class II/III mainline rail segments from their FRAprovided proprietary shapefile as described in Appendix B for the contiguous 48 states and 

Alaska. Raw rail line data for Puerto Rico were obtained from USGS (Scanlon and Briere, 

2000), and rail line data for Hawaii was obtained from ESRI’s Digital Chart of the World (ESRI 

2010). The U.S. Virgin Islands have no rail lines. Because Class II/III railroads are less likely to 

use rail segments that are heavily traveled by Class I railroads, the activity-based approach used 

for Class I lines was not appropriate. Instead, Class II/III line haul emissions were allocated to 

rail segments using segment length as a proxy. 

The county emission sums were reallocated to the segments by multiplying the county 

emissions by the segment’s length divided by the sum of the length for all links within the 

county.

lLC = Sum of allocation values for all links in county C from public BTS dataset 

Since ERTAC Rail used proprietary data to develop the shapefile, some segment IDs 

were not found in the EIS data set. These segments were manually identified, and their 

emissions were allocated to the nearest segment within the EIS data set. 
4-3 

4.3 Rail Yard Emissions Allocation 

Rail yard emissions were developed based on yard name and ownership properties. As a 

result, unique yards needed to be identified and emissions summed. Unfortunately, the yard data 

lacked detail necessary for confident duplicate checks and yard matching such as address, 

detailed yard name, etc. As a result, a GIS was used to find the centroid of the yards based on 

the latest public BTS rail network, using the yard name and FIPS. The list of unique yards was 

further examined against ERTAC’s data and within Google Earth to identify any yards that 

required further revision. A crosswalk of original ERTAC data to new, consolidated yard IDs 

facilitated the summing of activity and emissions. 753 unique yards were identified nationwide. 

This underestimate of the total number of yards is most likely due to using line-haul-focused data 

to identify locations and develop rail yard emissions. 

 Once the unique yards were identified and criteria emissions were summed at the yard, 

the PM and VOC-based HAP speciation profile was applied to estimate HAP emissions at each 

yard. 

4.4 State Provided Data 

In this version of NEI, state and local agencies were invited to provide locomotive data 

that replaced the estimates based on national fuel consumption. However, only a small rail yard 

dataset was received from Kentucky. Their rail yard list was compared with the ERTAC/ERG 

yard list, and 2 yards were found in both sets. These yards were merged so as to avoid 

duplication in activity or emissions.

Introduction 

Air protection agencies from twenty-seven states, coordinated through the Eastern Regional 

Technical Advisory Committee (ERTAC) and headed by the Lake Michigan Air Directors 

Consortium (LADCO), identified a need to better quantify and characterize rail-related emissions 

inventories. Traditional locomotives largely utilize diesel engines, resulting in emissions of 

NOx, diesel PM, hydrocarbons, greenhouse gases, and other pollutants. These emissions are 

sometimes concentrated in areas exceeding National Ambient Air Quality Standards. No 

cohesive nationwide railroad emission estimates based on local operations are known to have 

been made previously. Inventory development methods for locomotive emissions estimates vary 

from state to state and, in general, lack the spatial or temporal resolution needed to support air 

quality modeling and planning 1-5. 

The ERTAC Rail Subcommittee (ERTAC Rail) was established with active representatives from 

twelve member states, three regional planning offices, and the US EPA. The subcommittee’s 

goals are to (1) standardize agencies’ inventory development methods through a collaborative 

effort, (2) improve the quality of data received and the resulting emission inventories, and (3) 

reduce the administrative burden on railroad companies of providing data. 

With support from the Rail industry and assistance from the ERTAC Rail Data Workgroup 

(Appendix A), ERTAC Rail has developed 3 inventories of locomotive emissions (Table 1); 

from Class I line-haul, Shortline and Regional Railroads (Class II and III operations), and Class I 

railyard switchers. Because of the difficulty in obtaining data and differences in states’ needs for 

inventory years, sources from both 2007 and 2008 were utilized (Appendix B.) Due to the 

variability and uncertainty in much of the data, the results are considered applicable for either 

2007 or 2008. 
A-2 

The Surface Transportation Board (STB) defines Class I Railroads as having had minimum 

carrier operating revenues of $401.4 million (USD) in 2008. There are 8 Class I Railroads 

operating in the United States (Table 2), about 12 Regional Railroads (Class II), and 

approximately 530 Class III Railroads (Shortlines). While categorized as a Class I Railroad, 

Amtrak was excluded from these inventories because of significant differences in equipment and 

operation characteristics. Line-haul locomotives travel long distances (e.g. between cities) while 

switcher locomotives largely operate in railyards, splitting and joining rail cars with varying 

destinations. Passenger and Commuter Rail (including Amtrak), industrial locomotives, and 

associated non-locomotive equipment are not included in these inventories. 

This paper documents the data sources and methodologies used for calculating the Class I linehaul emissions inventory. Class I line-haul activities are the largest source of rail-related 

emissions, with estimates of Class I line-haul fuel consumption totals to be from 74 to 84% of all 

rail sources combined4, 5. For this reason, characterizing Class I line-haul emissions were a focal 

point of ERTAC Rail’s inventory development efforts. Information on ERTAC Rail, Railroad 

participation, the Rail industry, and effects of rail on air quality are available elsewhere6

Method 

Earlier efforts to characterize line-haul railroad emissions relied on highly aggregated activity 

data (Figure 1), and generally apportioned annual system-wide fuel use equally across all route 

miles of track operated by a Class I railroad. However, the majority of freight tonnage carried by 

Class I railroads is concentrated on a disproportionately small number of route miles. In 

addition, emissions calculations were previously based on an estimate of annual nationwideaverage locomotive fleet mix to create one set of emissions factors. 

For this inventory, the Class I Railroads allowed ERTAC Rail access under a confidentiality 

agreement to a link-level (single lengths of track) line-haul GIS layer activity dataset managed 

by the Federal Railroad Administration9. Each railroad also provided fleet mix information that 

allowed ERTAC Rail to calculate weighted emission factors based on the fraction of their linehaul fleet meeting each Tier level category. The use of this data, largely following a line-haul 

inventory methodology recommended by Sierra Research2, 3, resulted in a link-level line-haul 

locomotive emission inventory using railroad-specific emission factors. This segment-level 

inventory is nationwide, aggregated to state and county level files, and will be released as 

gridded emissions files for use in photochemical and dispersion modeling. Link-level emissions 

may be provided for special study requests pending approval of any Class I railroads operating in 

the study domain. The calculations are described below as a two-part process, calculating 

railroad-specific factors and emissions per rail link.

1. Calculate Railroad-Specific Factors.

The EPA provides annual default Emission Factors for locomotives based on characteristic 

operating cycles (‘duty cycles’) and the estimated nationwide fleet mixes for both switcher and 

line-haul locomotives. However, fleet mixes vary from railroad to railroad and, as can be seen in 

Figure 2, Class I railroad activity is highly regionalized in nature and subject to issues of local 

terrain such as operation on plains vs. mountainous areas, which can have a significant impact on 

fuel consumption and emissions. 

Figure 2. Class I Railroad Territories in the United States10. 

As an alternative approach to using a single nationwide set of emission factors, ERTAC Rail 

requested each Class I company to provide a description of their line-haul fleet mix based on 

Tier rating, which each company provided under a confidentiality agreement. An engine’s Tier 

level is based on the year the engine was built and determines allowable emission limits (Table 

3).

Based on values in EPA Technical Highlights: Emission Factors for Locomotives, EPA Office of 

Transportation and Air Quality, EPA-420-F-09-025, April 2009. 

Weighted Emission Factors (EF) per pollutant for each gallon of fuel used (gm/gal or lbs/gal) 

were calculated for each Class I railroad fleet based on its fraction of line-haul locomotives at 

each regulated Tier level (Eqn 1; Table 3).

 EFiT = Emission Factor for pollutant i for locomotives in Tier T (gm/gal) (Table 3). 

There were 4 Tiers of locomotives in the 2008 fleets. 

fTRR = Fraction of railroad RR fleet in Tier T. 

While engine emissions are variable within Tier categories, this approach likely provides better 

regional estimates than uniformly applying the nationwide average emission factors. This 

approach likely provides conservative emission estimates as locomotive engines are certified to 

meet or exceed the emissions standard for each Tier, although emission levels may increase after 

certification. 

Other emission factors are not engine specific. For locomotives, PM2.5 is assumed to be 97% of 

PM10

11, and emission factors applied for SO2 and NH3 are 1.88 g/gal 11 and 83.3 mg/gal 12

respectively. Greenhouse gases are estimated using emission factors shown in Table 4.

A Railroad Fuel Consumption Index (RFCI) was also calculated for each Class I railroad using 

their system-wide line-haul fuel consumption (FC) and gross ton-mile (GTM) data reported in 

their annual R-1 reports submitted to the Surface Transportation Board7

 (Eqn 2). This value 

represents the average number of GTM produced per gallon of diesel fuel used over their system 

in a year, and varies between railroad carriers depending on factors such as fleet mix, system 
A-6 

terrain, speeds, loading/weight of cargo, train type (e.g., intermodal, unit, and manifest), and 

operating practices. (Table 2).

 FCRR = Annual system-wide fuel consumption by line-haul and work trains per RR 

(gal) (R-1 Report Schedule 750, Lines 1 and 6). 

2. Calculate Emissions per Link.

Emissions of pollutant i per link L (EiL) are then calculated by multiplying the gallons of diesel 

fuel consumed by each Class I railroad on the link by that railroad’s weighted Emission Factor 

for the pollutant, and summed over all railroads operating on the link (Eqn 3). This approach 

splits the activity on each link (represented by MGT) evenly between all railroads operating on 

the link. Note that the weighted Emission Factors are converted to tons/gal for these 

calculations, and that variables with units in tons may represent tons of freight hauled (MGT, 

RFCI) or tons of pollutants (EF, E).

 EFiRR = Weighted Emission Factor for pollutant i per railroad RR (Eqn 1; tons/gal). 

 RFCIRR = Railroad Fuel Consumption Index per railroad RR (Eqn 2; gross

Note that approximately 36% of Class I route miles in the United States are shared by more than 

one Class I carrier, a fraction that drops to 26% when neglecting track only shared between one 

Class I freight railroad and Amtrak. Accurately apportioning the specific fractions of tonnage 

(MGT) per carrier per link was considered, but after comparing likely worst-case areas, the 

difficultly of merging carrier-specific MGT with the aggregated FRA MGT dataset was 

considered too great considering the potential gain in accuracy. Where warranted, MGT data 

may be apportioned more accurately in the future.

Limitations, Conclusions, and Future Work 

Rail-related emissions can be important components of emissions inventories used to support 

effective air quality management practices, at local, state, regional, and national levels. This linehaul inventory, as well as the companion Class I railyard inventory and Class II/III inventory, 

greatly improve our estimates of rail-related emissions. However, a systematic study of 

variability and uncertainty in line-haul locomotive emissions and activity, by fleets, locations, 

and through time, would give valuable information for identifying how to best improve this 

inventory as well provide an indication of how representative the inventory may be. An 

uncertainty study on the data used for this inventory, including the R-1 reported fuel use and the 

confidential link-level tonnage data, would also help in evaluating the quality of this inventory. 

Localized studies should also examine how shared tracks are apportioned between multiple 

carriers. 

Early ERTAC Rail discussions concluded that link-level tonnage was the most important data to 

obtain, while other variables such as track grade and track speed could not be addressed at this 

time. ERTAC Rail calculated railroad-specific fleet-averaged emission factors rather than 

applying the estimated national average; however, it is recognized that emissions from individual 

engines are highly variable even within Tier categories depending on variables such as the 

specific locomotive model, operation cycle, and conditions of operation. Future evaluation of 

emission variability within Tiers and between certain types of operation and locations would also 

be valuable. 

Emissions inventory preparation guidance from the U.S. EPA describes locomotive activity as 

relatively constant throughout the year (e.g. no daily, weekly, or seasonal variability); however, 

actual activity levels do vary seasonally and annual averaging may dilute or exaggerate 

concentrations during pollution episodes. ERTAC Rail and the Class I railroad community had 

some discussions addressing if incorporating more specific fleet mix or monthly or seasonal 

variation may be worthwhile, and these topics should be looked into further. 

Finally, it is important to reiterate that the link-level MGT data maintained by the FRA is 

proprietary and can only be released to agencies/groups outside the FRA with the express 

permission of each Class I railroad. It is possible that one or more Class I railroads could 

withhold permission for access, but data for specialized studies may be provided if requested. 

This database can also be improved by better distinguishing between haulage and trackage rights, 

and by apportioning tonnage hauled on links to specific carriers. 

We would like to thank the Class I Railroads and their representatives for their assistance and 

support in the development of this inventory.

ERTAC – Class 2/3 Shapefile Documentation 

13 Jul 2009 

Introduction 

This document outlines the methods and procedures used to compile a shapefile representing the 

links in the FRA 1:100,000 railroad dataset that are owned or operated by Class II and III 

railroad companies. It is important to note that there is a considerable amount of overlap 

between the Class II’s and III’s and the Class I and passenger railroads. Class II’s and III’s can 

operate on Class I or passenger rail links and vice versa. Although the final shapefile 

specifically represents Class II and III links, there are many Class I and passenger railroads 

represented as well. 

Procedure 

1. Started with all proprietary FRA links where “NET = ‘M’ and “STCNTYFIPS” <> ‘ ‘ 

(this definition query selects all active mainline links located within the United 

States). 

2. Ran 12 queries, one for each ownership and trackage rights field, to select all links 

not associated with a Class I freight railroad or Amtrak and not containing a null 

value (e.g., "RROWNER1" <> 'AMTK' AND "RROWNER1" <> 'BNSF' AND 

"RROWNER1" <> 'CN' AND "RROWNER1" <> 'CPRS' AND "RROWNER1" <> 

'CSXT' AND "RROWNER1" <> 'KCS' AND "RROWNER1" <> 'NS' AND 

"RROWNER1" <> 'UP' AND "RROWNER1" <> ' '). The first query was setup as a 

new selection. Each of the 11 subsequent queries were setup to add records to initial 

set of records. 26,261 links were selected and exported to a new shapefile. 

3. Due to the multitude of railroad codes used to represent commuter rail operations 

across the country, additional processing was required to remove any links that were 

not operated by a Class II or III freight railroad. Each commuter railroad was queried 

out of the new shapefile and the links analyzed to eliminate all links where no Class II 

or III operations were occurring. The following commuter rail operations were 

evaluated: NJT (New Jersey Transit), MNCW (Metro-North Commuter Railroad), LI 

(Long Island Railroad), CDOT (Connecticut DOT), MBTA (Massachusetts Bay 

Transportation Authority), SEPA (Southeastern Pennsylvania Transportation 

Authority), MARC (Maryland Area Rail Commuter), VRE (Virginia Railway 

Express), MTRA (Northeastern Illinois Regional Commuter Railroad), CSS 

(Northern Indiana Commuter Transportation District), DART (Dallas Area Rapid 

Transit), SCRA (Southern California Regional Rail Authority – including also SCAX, 

LACM, LAPT, and LATC), TCRA (South Florida Regional Transportation 

Authority), PJPB (Caltrain), and ACE (Altamont Commuter Express). 
B-2 

Approximately 1581 links were identified with no Class II or III operations and were 

deleted from the Class 2/3 shapefile. 

4. The remaining Class II and III links were then compared to the regional maps 

contained in the July-August issue of The Official Railway Guide to assess the 

completeness of the Class 2/3 shapefile. Six specific edits were made to the shapefile 

to correct the most glaring errors: 1) BMLP links deleted (Black Mesa & Lake 

Powell, an electric coal hauling railway in Arizona); 2) DSNG links deleted (Durango 

& Silverton steam tourist railroad in Colorado; 3) CIC haulage rights links on CN 

from Chicago to Omaha deleted; 4) DMIR links deleted (Duluth, Missabe & Iron 

Range, now owned and operated by CN in Minnesota; 5) EVWR’s ex-CSXT links 

coded from Evansville, IN to Okawville, IL (Evansville Western Railroad); 6) INRD 

ex-CP links coded from Chicago, IL to Louisville, IN (Indiana Rail Road). 

5. During the course of reviewing the FRA dataset, 555 “active” links were found to 

have no ownership or trackage rights codes. 1005 links have no codes listed in the 3 

ownership fields. In most cases these links are very short and scattered across the 

country. Only the links representing the EVWR and INRD spanned large distances 

and were fixed. The other problem links were deemed to be insignificant. A listing of 

these links will be provided back to the FRA to assist with their coding in 1:100K 

railway shapefile.

Introduction 

Air protection agencies from twenty-seven states, coordinated through the Eastern Regional 

Technical Advisory Committee (ERTAC) and headed by the Lake Michigan Air Directors 

Consortium (LADCO), identified a need to better quantify and characterize rail-related emissions 

inventories. Traditional locomotives largely utilize diesel engines, resulting in emissions of 

NOx, diesel PM, hydrocarbons, greenhouse gases, and other pollutants. These emissions are 

sometimes concentrated in areas exceeding National Ambient Air Quality Standards. No 

cohesive nationwide railroad emission estimates are known to have been made previously. 

Inventory development methods for locomotive emissions estimates vary from state to state and, 

in general, lack the spatial or temporal resolution needed to support air quality modeling and 

planning 1-5. 

The ERTAC Rail Subcommittee (ERTAC Rail) was established with active representatives from 

twelve member states, three regional planning offices, and the US EPA. The subcommittee’s 

goals are to (1) standardize agencies’ inventory development methods through a collaborative 

effort, (2) improve the quality of data received and the resulting emission inventories, and (3) 

reduce the administrative burden on railroad companies of providing data. With support from 

the Rail industry and assistance from the ERTAC Rail Data Workgroup (Appendix), ERTAC 

Rail has developed 3 inventories of locomotive emissions; from Class I line-haul, Shortline and 

Regional Railroads, and Class I railyard switchers, for the year 2008 (Table 1). 

The Surface Transportation Board (STB) defines Class I Railroads as having had minimum 

carrier operating revenues of $401.4 million (USD) in 2008. There are 8 Class I Railroads 

operating in the United States (Table 2), about 12 Regional Railroads (Class II), and 

approximately 530 Class III Railroads (Shortlines). While categorized as a Class I Railroad, 

Amtrak was excluded from these inventories because of significant differences in equipment and 

operation characteristics. Line-haul locomotives travel long distances (e.g. between cities) while 

switcher locomotives largely operate in railyards, splitting and joining rail cars with varying 

destinations. Passenger and Commuter Rail (including Amtrak), industrial locomotives, and 

associated non-locomotive equipment are not included in these inventories.

This paper documents the data sources and methodologies used for calculating the Class I 

switcher (“Railyard”) inventory. Information on ERTAC Rail, Railroad participation, the Rail 

industry, and effects of rail on air quality are available elsewhere6

. 

Method 

Switcher locomotives are expected to be the single largest source of air emissions in railyards. 

Therefore, as a starting point for a comprehensive railyard inventory, a Class I switcher emission 

inventory was developed. It is assumed that estimates for yards of interest, associated equipment 

and activity, and smaller railroads could be refined later. 

While ERTAC Rail represents states east of the Mississippi River, the railroad companies 

specified they wanted this effort to result in a consistent nationwide inventory. ERTAC Rail 

agreed to calculate emissions for all states when the data was available and when additional 
C-3 

significant effort was not required. Because both the dataset of railyards and switcher fuel use 

was nationwide in scope, the resulting initial railyard inventory is a nationwide, ‘top-down’ 

derivation. However, railroad companies may have different levels and quality of data available, 

and may have interpreted some data requests differently. Also, states are requested to update 

yards they have detailed information on when possible, and a few states (i.e. California) have 

unique railroad operations and equipment. Therefore, data for some areas will be more accurate 

than for others, and locally-derived inventories may be more accurate. 

This documentation describes development of the initial top-down inventory, which consisted of 

three main activities: 

1. Locate Class I Railyards 

2. Select/Calculate Emission Factors 

3. Estimate Locomotive Activity 

4. Improve Estimates 

1. Locate Class I Railyards. 

Identification and correct placement of railyards was an important first step, requiring a 

comprehensive electronic dataset. A confidential database was obtained from the Federal 

Railroad Administration (FRA) with permission from the Class I Railroads (FRA database). A 

similar public database compiled by the Bureau of Transportation Statistics is also available7

 . 

Data from this source will not match the confidential data exactly, but will be very similar. The 

FRA database has rail links (track lengths) individually identified as parts of specific railyards. 

While there may be discrepancies in how each railroad defined railyard links, this dataset 

appears to identify most Class I railyards in the U.S., and shows a high density of yards in the 

eastern states (Figure 1). The database gives length, up to 3 owners and 3 operators, and a 

Federal Density Code (explained below) for each railyard link. 

Figure 1. Class I Railyards in the United States and estimates of Annual NOx 

emissions from switcher locomotives (tons/yr in 2008). 
C-4 

2. Select/Calculate Emission Factors.

The EPA provides annual default emission factors based on characteristic operating cycles (‘duty 

cycles’) and the estimated nationwide fleet mix for both switcher and line-haul locomotives. 

However, switcher fleet mix is not uniform from company to company and, as can be seen in 

Figure 2, Class I railroad activity is highly regional. 

As an alternative approach, ERTAC Rail requested each Class I rail company to provide a 

description of their switcher fleet mix based on Tier rating, which each company provided under 

a confidentiality agreement. An engine’s Tier determines allowable emission limits based on the 

year the engine was built (Table 3). While engine emissions are variable within Tier categories, 

this estimate likely provides a better regional estimate than the nationwide average. The 

company-specific systemwide fleet mix was used to calculate weighted average emissions 

factors for switchers operated by each Class I railroad.

For locomotives, PM2.5 is assumed to be 97% of PM10

, and emission factors for SO2 and NH3

are 1.88 g/gal and 83.3 mg/gal respectively (add cites). Greenhouse gases are also estimated 

using emission factors shown in Table 4.

http://www.epa.gov/climatechange/emissions/usinventoryreport.html

These emission factors are based on a characteristic duty cycle for switchers which assumes 

operation over 24-hour per day 365 days per year. An evaluation of the effect of variability in 

railyards and switching duties on emissions would be useful for future inventories. 

3. Estimate Locomotive Activity.

Class I railroads report total annual switcher locomotive fuel use to the STB, which is reported in 

publicly available ‘R-1’ reports (Table 2). There may be inconsistencies between railroads in 

how fuel use is estimated to be apportioned between line-haul and switcher locomotive use, and 

possibly in the total locomotive fuel use, so these values may be adjusted in the future. 

However, the use of these values provides a starting point for estimating total U.S. Class I 

locomotive-related emissions segregated by Class I carrier. The R-1 report was used by ERTAC 

for both the line-haul and switcher locomotive emissions inventories. 

The next step for inventory development is to allocate switcher fuel use to each railyard. Two 

methods were applied, one that relies on publicly available line-haul activity (the ‘Dencode’ 

method), and the other using confidential line-haul activity (the ‘MGT’ method.) At this time, 

Norfolk Southern and Kansas City Southern have provided input for use of the MGT method and 

the Dencode method is applied for the other five railroads. 

The Dencode Method – Publicly available data 

Each link in both the publicly available BTS database and the confidential FRA database has a 

‘Federal Density Code’ (Dencode) ranging from 1 to 7 assigned based on the cumulative annual 

freight tonnage hauled on the link (track). Total Switcher Fuel Use in each railyard Y (SFUY) is 

estimated as follows: 

First the Switcher Activity Indicator per yard (SAIY) is estimated by multiplying the average 

dencode of the links identified as part of the same railyard by the sum of the length of the links 

for that railyard (Eqn 1). 

SAIY = ( * ) nY FDCnY ∑ l Equation 1 

SAIY = Switcher Activity Indicator in Railyard Y 
C-6 

nY = number of links identified as part of railyard Y 

lnY = length of link n in miles 

FDCn = Federal Density Code (1 to 7) of link n 

Next, this value is then weighted (SAIY’) based on an ownership factor (OF) set between 0 and 1. 

The OF depends on the number of owners listed for each railyard: if there is one owner the OF 

is set to 1, if there are two owners the primary owner is set to 0.8 and the secondary is 0.2, and if 

there are 3 owners the primary is 0.6, the secondary is 0.2, and the tertiary is 0.1. 

SAIY’ = OFY* SAIY Equation 2 

Next, the SAIY’ of all railyards belonging to a Class I railroad (RR) were summed, and the 

fraction of the railroads total SAI associated with each railyard was multiplied by the railroads 

total annual switcher fuel use reported in the R-1 (TFURR), resulting in the total Switcher Fuel 

Use for each railyard Y (Eqn 2). 

SFUY = RR

∑ Equation 3 

SFUY = Switcher Fuel Use at railyard Y 

Finally, the SFUY is multiplied by the emission factors described in the previous section to 

obtain annual switcher emissions at each railyard. 

The MGT Method – Confidential data 

Two railroads, Norfolk Southern and Kansas City Southern, provided confidential link-level 

tonnage information and weighting factors to correct skewed estimates to improve estimated 

switcher activity at important yards. Other railroads may also allow the use of this technique for 

their inventories in the future. 

The MGT Method also uses the FRA database for railyard identification and link lengths. 

However, rather than using the average dencode per link, confidential annual gross tonnage 

(MGT) hauled per link in the railyard was used to calculate the railyard switcher activity (SAIY). 

This is calculated by replacing FDCn in Equation 2 with link-specific tonnage MGTn (Equation 

4). 

SAIY = ( * ) nY MGTnY ∑ l Equation 4 

SAIY = Switcher Activity Indicator in Railyard Y 

nY = number of links identified as part of railyard Y 
C-7 

lnY = length of link n in miles 

MGTnY = million gross tons on link n 

This method provides a more refined comparison between railyards than the use of the 7-

category dencodes; however, is more susceptible to errors for yards where tonnage is not 

correlated to switching activity. For example, a yard with large coal trains pulling through used 

for crews to change over would be assigned an overly high level of emissions for switching 

activity. To account for this, a discretionary Switching Activity Factor (SAF) was introduced to 

allow railroads to roughly weight yards with clearly higher or lower levels of switching activity 

than what results from the mathematical allocation. Therefore, SAIY is weighted based on both 

the ownership factor (OF) as well as the SAF (Equation 5). For example, a yard used for crew 

changes and not switching may have an SAF of 0, while a yard at a major interchange between 

cities may have an SAF of 3. 

SAIY’ = OFY*SAFY* SAIY Equation 5 

Again, the SAIY’ of all railyards belonging to a Class I railroad (RR) are summed, and the 

fraction of the railroads total SAI associated with each railyard was multiplied by the railroads 

total annual switcher fuel use reported in the R-1 (TFURR), resulting in the total Switcher Fuel 

Use for each railyard Y (Eqn 6). 

SFUY = RR

∑ Equation 6 

While the SAF allows estimates of yard-specfic emissions to be adjusted, the total level of 

emissions for each railroad, which is based on systemwide fuel use and systemwide emission 

factors, remains unchanged. The MGT method SFUY is also later multiplied by the emission 

factors described in the previous section to obtain annual switcher emissions at each railyard. 

4. Improve estimates.

In addition to the Switching Activity Factor described above, direct input was also used to 

improve emission estimates for important railyards. Each Class I railroad provided an estimate 

of annual average switcher fuel use (generally much lower than the EPA default of 82,490 

gal/yr) as well as the name, location, and number of operating switchers for railyards with 8 or 

more switchers operating in ozone or PM2.5 nonattainment areas. This data was used to 

overwrite the dencode or MGT derived emissions estimates for those railyards. 

The difference in estimated fuel use for those railyards was re-allocated (added or removed) 

between the remaining railyards belonging to that Class I railroad. It is important to note that 

there are some discrepancies in how this data was reported for the large railyards by each 

railroad. For example, some railroads reported all switchers located at a railyard while others 

reported ‘full time equivalent’ switchers, meaning the number of switchers normalized to a full 

working cycle (24-hours per day year-round.) This process should be standardized for future 

inventory versions. 
C-8 

States also have the option of updating specific railyard emissions estimates. Because this 

inventory is derived ‘top-down’, local studies and familiarity with specific railyards is expected 

to provide better estimates, which can be used to adjust this inventory. Care must be taken to 

ensure the other railyard estimates are adjusted to account for increases or decreases in estimated 

fuel use per yard. 

Limitations, Conclusions, and Future Work 

What this ERTAC Rail railyard inventory does well is provide a comprehensive overview of 

where railyards are, who owns them, and gives a geographical allocation of switcher emissions 

bounded by what is reported as nationwide switcher fuel usage by the Class I railroads. These 

sources can be important for air quality management in nonattainment areas, as well as in 

regional analysis and for future transportation planning. This inventory will be useful for 

regional and some local modeling, helps identify where railyards need to be better characterized, 

and provides a strong foundation for future development of a meaningful nationwide Class I 

switcher emissions inventory. 

There are important uncertainties associated with estimates from this method, including, but not 

limited to, the use of tonnage hauled as an indicator of the amount of switching activity, and, for 

a few of the railroads, how the amount of switcher fuel use was determined to be reported in the 

R-1. The R-1 reported values are currently under examination. 

There is also likely significant variability in actual switching duty-cycles and, potentially, in the 

number of switchers operating at some railyards at different times of the year. ‘Road-switching’, 

or the use of what are considered switching locomotives to move between nearby yards, should 

be addressed in either this or the ERTAC line-haul inventory. 

It must be noted that freight-related rail activity is not always routine and no annual emissions 

inventory will ever be able to capture the innate variability of the source. However, as other 

large emission sources are reduced, and if rail activity increases as expected, it is important to 

include our best estimates of these sources in air quality analysis. In the future, on-line data 

loggers and other tracking technologies, combined with ambient studies and detailed modeling, 

will hopefully provide more insight to the emissions of locomotives and other railyard sources.

A. INTRODUCTION 

The objective of this project is to estimate area source emissions from Industrial and 

Commercial/Institutional (ICI) fuel combustion for the CENRAP region, which encompasses the 

States and tribal areas of Arkansas, Iowa, Kansas, Louisiana, Minnesota, Missouri, Nebraska, 

Oklahoma, and Texas. This project will result in the development of a set of revised 2002 ICI 

area source emission inventories for sulfur dioxide (SO2), nitrogen oxides (NOx), non-methane 

volatile organic compounds (VOCs), particulate matter (specifically, PM10 and primary/direct 

PM2.5), ammonia (NH3), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The 

emission inventories will be developed at the county level and will provide emissions for the 

following time periods: annual; monthly; and average weekly, weekday, and weekend day 

emissions for each month. 

This technical memorandum is one of two components for documenting the methodology that 

E.H. Pechan & Associates, Inc. (Pechan) will follow in preparing CENRAP’s 2002 ICI area 

source emissions inventory. The second component is a set of Microsoft® Excel workbook 

templates that Pechan will use to implement the methodology described in this document. This 

memorandum is organized into four sections: this section (Introduction), Section B 

(Methodology) , which describes the emission estimation methodology, Section C (Calculation 

Templates), which summarizes the content of the calculation templates, and Section D 

(References), which identifies the information sources that were consulted in preparing this 

document. 

B. METHODOLOGY 

This section documents the emission inventory development methodology that Pechan will use 

to prepare an ICI combustion area source emission inventory for the CENRAP States. Table 1 

identifies the source classification codes (SCCs) for which Pechan plans to prepare ICI 

combustion area source emission estimates. It is important to note that some of these SCCs may 

not ultimately appear in each CENRAP State’s inventory. If it is determined that all of an 

individual State’s consumption of a particular fuel is already accounted for in the State’s nonroad 

and/or point source inventory, then the SCC for that fuel will not be included in the area source 

inventory for that State. 

The key data inputs in the emissions estimation methodology are: 

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

CENRAP State for the year 2002; 

2. Industrial energy consumption used for non-fuel purposes by fuel type and State in 2002; 

3. ICI distillate fuel and liquefied petroleum gas (LPG) consumption for nonroad sources by 

State in year 2002; 

4. ICI energy consumption by fuel type for point sources by CENRAP State in year 2002; 

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

the ICI sectors;

7. County-level employment in the ICI sectors by State for the year 2002; and 

8. Temporal allocation data for estimating the proportion of annual fuel combusted by 

month, as well as data for estimating the volume of fuel combusted in each month for the 

following time-frames: average week, average week day; and average weekend day. 

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

data inputs. The following identifies the planned source(s) of information for each of these data 

elements. In selecting the information sources for each of these data elements, Pechan evaluated 

the representativeness and level of confidence 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 are less specific. 

1. Total ICI Energy Consumption 

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

Pechan will use the same source that EPA uses in developing ICI combustion emission estimates 

for the National Emissions Inventory (NEI) – the Energy Information Administration (EIA)’s 

State Energy Data System (SEDS) (EIA, 2009a). The SEDS reports total energy consumption 

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

GHG emission factors, Pechan will compile the SEDS energy consumption data in both sets of 

units provided by the SEDS: physical units and British thermal units (Btus). 

2. 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.1

 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. In 

particular, the EIA Industrial sector includes fuel consumption from Farm, Mining, Construction, 

and Commercial sectors that is accounted for in the nonroad inventory. Because of these 

limitations, Pechan plans to use regional non-fuel use percentages computed from energy 

consumption data from the EIA’s 2002 Manufacturing Energy Consumption Survey (MECS) for 

all fuel types except coal (EIA, 2007). There are two reasons why MECS provides a more 

representative data set for use in this study: (1) MECS provides data specific to the regions 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

 Although the SIT also develops CO2 emission estimates associated with non-fuel energy use, such estimates are 

not developed here because they are not associated with industrial fuel combustion.

coal that is used to produce coke as a feedstock. However, available data indicate that none of 

the CENRAP States produce coke (Pechan, 2006). In addition, the 2002 MECS data treat 

“synthetic coal” that is ultimately combusted as regular coal, as a non-fuel (feedstock) use. 

Because of these data limitations, Pechan contacted EIA for assistance in obtaining a reasonable 

estimate of the percentage of non-coking coal that is used for non-fuel purposes (treating 

“synthetic coal” as a fuel use). Based on the EIA’s estimate that 5-10 percent of 2002 non-coke 

coal was used for non-fuel purposes, Pechan plans to assume that 7 percent of CENRAP 

Industrial sector coal consumption is for non-fuel purposes (Lorenz, 2009). 

Table 2 presents the available non-fuel use percentages by type of energy. It was not possible to 

develop percentages by region for each fuel type because some regional MECS data are 

withheld. For this study, Pechan plans to use the most geographic-specific data reported in Table 

2. States are encouraged to provide available State-specific estimates to replace the defaults 

below.

South region includes Arkansas, Louisiana, Oklahoma, and Texas. 

3. Nonroad Source Energy Consumption 

To avoid double-counting with the nonroad inventory, it is necessary to subtract 2002 year diesel 

and LPG consumption estimates for Industrial, Farm, Logging, Mining, and Construction sector 

nonroad equipment. For the Commercial sector SEDS data, it is necessary to subtract 2002 year 

diesel and LPG consumption for Commercial sector nonroad equipment. Pechan plans to run the 

NONROAD model for 2002 for the CENRAP States to obtain State-level diesel and LPG 

consumption estimates to perform these subtractions. Table 3 identifies the SCCs for which 

Pechan will compile NONROAD fuel consumption estimates.

4. Point Source Energy Consumption 

To ensure that energy consumption is not double-counted in the point source inventory, it will 

also be necessary to subtract point source inventory fuel use from the fuel consumption estimates 

developed from the aforementioned data sources. To assist in the point source subtractions, 

Pechan has developed two crosswalks: one between each Industrial fuel combustion area SCC 

and associated point SCCs (Table 4), and an analogous crosswalk for Commercial/Institutional 

fuel combustion (Table 5). Pechan requests CENRAP comments on the point SCCs included in 

these crosswalks. 

In addition, a summary analysis was performed on the throughput data reported in the 2002 point 

source inventory compiled for CENRAP (Pechan/CEP, 2005). The Attachment to this 

memorandum provides a summary of the 2002 annual point source throughput data associated 

with the ICI area source categories (reflecting use of the Table 4 and 5 crosswalks). As indicated 

by this summary, there appear to be numerous potential reporting errors in the CENRAP point 

source inventory throughput information. These errors include throughput reported using 

inappropriate units (e.g., reporting natural gas throughput in tons and distillate fuel throughput in 

million cubic feet), and throughput reported using an inappropriate material code (e.g., reporting 

a distillate fuel combustion category’s throughput as water). There are also records with 

emissions that report throughput as zero and throughput data reported without any unit 

identifiers. Pechan requests guidance from CENRAP States as to revisions to the throughput 

information to ensure the validity of the data that are used in the point source subtractions. For 

States/source categories with suspect values for which revisions are not available, Pechan will 

estimate throughput by dividing point source emissions by the carbon monoxide (CO) emission 

factors listed in the next section. The CO-based approach will also be used for all States that do 

not report any throughput data for ICI point source fuel combustion categories (i.e., Louisiana 

and Texas). 

To ensure that the methodology results in accurate estimates of point source throughput, Pechan 

will supply States with the SEDS energy consumption estimates by fuel type and the point 

source energy consumption by fuel type computed using the throughput or CO emissions-based 

approach. Pechan will wait for State approval of these estimates before final use in the point 

source subtraction procedure.

5. Emission Factors 

Table 6 presents the criteria pollutant emission factors that will be applied to fuel consumption 

estimates to calculate ICI combustion area source emissions. Except as noted below, all criteria 

air pollutant emission factors were from an EPA database of emission factors that will be used in 

preparing the 2008 nonpoint source NEI (Huntley, 2009).2 Wood combustion emission factors 

were compiled from AP-42 (EPA, 2003). 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 will use emission factors reported in an NH3 emissions Emission Inventory Improvement 

Program (EIIP) guidance document (Pechan, 2004). Pechan compared the 2008 NEI emission 

factors with those used to develop the last area source NEI (2002), as well as those listed by the 

Eastern Regional Technical Advisory Committee (ERTAC) for potential use by States in 

developing their area source inventories (ERTAC, 2009). With a few notable exceptions, the 

2008 NEI emission factors are the same as those used for the 2002 NEI.3 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 SCC-specific adjustment factors to apply to the 

2002 NEI to better reflect PM emissions from these fuels.4

 In preparation for the 2008 NEI, EPA 

developed revised natural gas and LPG PM emission factors by applying these adjustment 

factors to the 2002 NEI emission factors. 

Pechan does not plan to use the ERTAC emission factors that differ from the 2008 NEI factors 

because of the lack of documentation as to the source of the ERTAC factors. For PM emissions 

from ICI bituminous coal combustion, ERTAC specifically notes that their proposed emission 

factors reflect combustion in an uncontrolled overfeed stoker. The EPA PM emission factors for 

these categories, which were obtained from AP-42, reflect coal-fired boilers with controls 

(specifically, multiple cyclones with or without fly ash reinjection). Because an analysis of an 

EPA boiler database indicates that most small coal-fired boilers have PM controls (with cyclones 

as the most common type of control), EPA’s PM emission factors will be used in preparing the 

CENRAP emission inventory (ERG, 2002). 

For greenhouse gases (GHGs), Pechan will use the emission factors from EPA’s State 

Greenhouse Gas Inventory Tool, which incorporates the EIIP’s GHG emissions inventory 

guidelines for States (EPA, 2009). Table 7 displays the State-specific CO2 emission factors for 

each ICI combustion area source category, and Table 8 presents the N2O and CH4 emission 

factors by source category. Because SIT assumes that CO2 emissions from U.S. biomass 

combustion need not be inventoried, the SIT does not provide CO2 emission factors for ICI wood 

combustion.5 Therefore, Pechan will use the wood combustion CO2 emission factors reported in 

AP-42 (EPA, 2003).

 

2

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

3

 The 2002 NEI documentation provides citations to the AP-42 source for each emission factor (Pechan, 2006). 

4

 These factors reduce PM emissions by more than 90 percent. 

5

 As stated in the EIIP fossil fuel combustion CO2 emissions guidance: “...biomass fuels are generally grown on a 

sustainable basis. ... In cases where biomass fuels are not grown sustainably, GHG emissions are captured as a land 

use change.”

6. Coal Sulfur Content 

Under a forthcoming task (Task 4), Pechan will evaluate the reliability of various data sources 

for coal sulfur content before identifying the source(s) that will be used to estimate emissions in 

this project. Pechan will review potential coal sulfur content data sources, including: 
26 of 53

(1) information reported in the point source inventories of each State;6

 (2) the USGS’ U.S. Coal 

Quality Database (this is the ICI coal sulfur content source used in the 2002 NEI); (3) plant-level 

data from the Federal Energy Regulatory Commission’s (FERC) Form 423;7

 and (4) State-level 

data reported in EIA’s “Monthly Report of Cost and Quality of Fuels for Electric Plants.” 

Pechan will evaluate these and any other identified alternative data sources for use in this project 

to ensure that the data are as representative as possible with respect to consuming sector, 

geography, and time-frame. Any data sets that are deemed equally representative will next be 

evaluated with respect to level of confidence (i.e., a data source for which estimated coal content 

is based on more data points than other data sources will be deemed to have higher confidence, 

and therefore, the preferred data source). Pechan will prepare a memorandum identifying the 

coal content data sources that were reviewed and a priority ranking of preferred sources based on 

an evaluation of the aforementioned criteria. The memorandum will identify the preferred 

approach for characterizing the sulfur content of coal consumption for each ICI area source 

combustion source category, which will be incorporated into the Excel calculation templates. 

7. County Allocation Data 

After computing State-level emissions using the data described above, the project requires 

allocating these emissions to individual counties. There are two allocation approaches that 

CENRAP is evaluating for this step. The first, which has been used in past inventory efforts 

including the 2002 NEI, is based on each county’s proportion of total State employment for the 

energy-consuming sectors for each source category. The second is based on estimates of total 

energy consumption for each sector. For both approaches, the initial step is to identify the 

economic sectors associated with Industrial fuel combustion, and the economic sectors 

associated with Commercial/Institutional fuel combustion. 

Commercial/Institutional 

For area source Commercial/Institutional fuel combustion, the 2002 NEI used employment data 

in North American Industrial Classification System (NAICS) codes 42, 44-45, 51-54, 56, 61-62, 

71-72, and 81 to allocate EIA State Commercial sector energy consumption data to counties.8

 

These NAICS codes suggest that fuel combustion emissions for the following sectors are 

covered elsewhere in the NEI: Agriculture, Forestry, Fishing and Hunting; Mining; 

Construction; Manufacturing; Transportation and Warehousing; Management of Companies and 

Enterprises; and Public Administration. Meanwhile the EIIP area source method abstracts for 

Commercial/Institutional fuel combustion categories identify Standard Industrial Classification 

(SIC) codes 50-99 as representing the Commercial/Institutional sector. These SIC codes indicate 

that the following is the comprehensive list of non-Commercial sectors: Agriculture, Forestry, 

Fishing and Hunting; Mining; Construction; Manufacturing; and Transportation, 

Communications, Electric, Gas, and Sanitary Services. 

 

6

 Iowa has stated that they did not report coal sulfur content information in their 2002 point source inventory. 

7

 Note that these data include Commercial and Industrial combined heat and power producers whose total fossilfueled nameplate generating capacity is 50 or more megawatts. 

8

 These NAICS codes are also listed in ERTAC’s area source methodology worksheet (ERTAC, 2009). 
27 of 53

Documentation for the SEDS is not entirely clear on the NAICS codes associated with the 

Commercial sector, defining the Commercial sector as “an energy-consuming sector that consists 

of service-providing facilities and equipment of: businesses; Federal, State, and local 

governments; and other private and public organizations, such as religious, social, or fraternal 

groups. The Commercial sector includes institutional living quarters. It also includes sewage 

treatment facilities.” In an attempt to further clarify the NAICS codes associated with this 

sector, Pechan performed additional research into the original data sources that are used to create 

the SEDS. 

Because data for the SEDS originates with data collected from EIA fuel sector-specific surveys 

of energy suppliers,9

 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, suggesting that both the EIIP 

guidance and NEI definitions of the Commercial fuel combustion source category are missing 

some sectors, while also including one sector that should not be included (Private Households). 

In lieu of additional information, data for the CBECS-identified NAICS codes (42 though 92 

with exception of 814) will be used to allocate SEDS energy consumption data to individual 

counties. 

Industrial 

Although there are no EIIP guidance documents for area source Industrial fuel combustion, the 

2002 NEI used the Manufacturing sector NAICS codes (31-33) to represent this category. 

Unlike the Commercial sector, the SEDS 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, this indicates that a 

portion of Industrial sector consumption is already accounted for in other emission inventory 

sectors. It is expected that non-Manufacturing sector Industrial fuel consumption will largely be 

eliminated via the nonroad subtractions described earlier. Therefore, Pechan will 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). 

Standard Employment-Based Approach 

 

9

 For natural gas, for example – EIA-176 “Annual Report of Natural and Supplemental Gas Supply and 

Disposition.” 
28 of 53

In keeping with EIIP guidance and past EPA practice, employment data can be used to allocate 

State-level emission estimates to counties. Each year the Census Bureau releases County 

Business Patterns (CBP), a county level data set of employment by NAICS code (Census, 2009). 

The CBP county-level employment estimates for 2002 can be compiled for the appropriate 

NAICS codes noted above. 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. To estimate data for withheld counties/NAICS 

codes, Pechan used the following procedure. 

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.

1. The total of employees not including counties 015 and 023 is 52,801. 

2. The State-level CBP reports 59,322 employees in NAICS 31----the difference is 6,521. 

3. County 015 is given a midpoint of 1,750 (since range code F is 1,000-2,499) and County 023 

is given a midpoint of 17,500. 
29 of 53

4. State total for these two counties is 19,250. 

5. 6,521/19,250 = 0.33875. 

6. The final employment estimate for county 015 is 1,750 * 0.33875 = 593. The county 023 

final employment estimate is computed as 17,500 * 0.33875 = 5,928. 

Energy Intensity-Adjusted Approach 

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. Therefore, Pechan recommended that CENRAP 

consider utilizing energy use per employee values by NAICS code to refine the employmentbased county allocation approach. Because State/NAICS code-level energy use data are not 

available, this approach relies on 2002 national energy consumption data by NAICS code as 

reported by EIA in Annual Energy Outlook (EIA, 2005). Energy intensity values are computed 

by dividing these Btu-based energy consumption estimates by 2002 national employment data by 

NAICS code. The resulting intensity values are then multiplied by county/NAICS code-level 

employment estimates to estimate total county energy consumption by NAICS code. These 

values are then summed for the appropriate Industrial and Commercial/Institutional fuel 

combustion NAICS codes. The resulting county-level total Industrial and total 

Commercial/Institutional energy consumption estimates can then be used to apportion State-level 

Industrial fuel combustion emissions and State-level Commercial/Institutional fuel combustion 

emissions to each county. 

Table 9 displays a comparison of the county-level allocation percentages computed for Missouri 

from the two methods. This table is sorted in descending order based on each county’s Industrial 

fuel combustion employment-based allocation percentage. The cells shaded in green indicate 

that the energy intensity-adjusted approach reflects a greater than 50 percent higher allocation of 

activity/emissions to the given county versus the employment-based approach. Similarly, cells 

shaded in tan indicate that the energy-based approach reflects an allocation that is more than 50 

percent lower than that resulting from the employment-based approach. The table shows that the 

Industrial sector allocations differ more substantially between the two methods in Missouri. 

Focusing on the Industrial sector allocation percentages for Jackson county, for example, overall 

Manufacturing sector employment is approximately 10 percent of the Missouri total. However, a 

much higher percentage of Missouri total Industrial sector energy consumption is estimated for 

this county (~17 percent). A closer look at the underlying data indicates that this county has a 

relatively high proportion of total State employment in the Chemicals and Paper industries that 

are the third and fifth highest energy-intensive manufacturing sector industries. Pechan will 

provide the information in Table 9 for all CENRAP States when it submits the Task 3 State-level 

fuel consumption estimates, which are due by April 17.

8. Temporal Allocation Data 

The EPA provides national default temporal allocation data via the “temporal allocation” section 

of their Emissions Modeling Clearinghouse (EMCH). For all Industrial sector fuel types, the 

EPA default is for an equal distribution of annual activity across months. For the Commercial 

sector, the EPA default is for an equal distribution of annual activity across months for LPG and 

kerosene, but the EPA default distribution for all other fuel types is as displayed in Table 10.

distribution assumed throughout year). 

Pechan researched the availability of more representative (sector, geographic, and/or timespecific) energy consumption data than that used to develop the EMCH’s temporal allocation 

factors. The following summarizes the available information: 

 Natural Gas – State-level volume delivered data are available by month and sector 

(Industrial versus Commercial) for 2002; 

 Coal – national consumption data are available by month and sector (Industrial versus 

Commercial) for 2002; and 

 Petroleum products (i.e., distillate, residual, LPG, kerosene) – regional level product 

supplied data are available by month for 2002. 

Pechan was unable to identify a source reporting sub-annual consumption estimates for wood. 

Pechan plans to use EIA’s State-level natural gas deliveries data for 2002 to allocate the annual 

SEDS data to each month (EIA, 2009b). Given the limitations of the available coal and 

petroleum product data, and the lack of data for wood, Pechan plans to apply EPA’s monthly 

default profiles to allocate annual activity/emissions for these fuel types. Because Pechan was 

unable to identify any source of sub-monthly estimates of ICI energy consumption, the EPA 

default allocation profiles will be used to develop average weekday, average weekend day, and 

average weekly emission estimates for each month.

C. CALCULATION TEMPLATES 

This section summarizes the draft templates that Pechan has produced to develop the ICI 

combustion area source emission estimates for CENRAP. CENRAP should not review the 

actual data in these draft templates at this time because some entries are currently missing or 

represent “dummy” placeholder values. Pechan will provide completed templates for CENRAP 

review by April 17 as required under Task 5. 

Template 1 – Adjust SEDS Fuel Consumption – this workbook, which reflects the discussion in 

sections B.1 through B.4, performs the following tasks: 

 Computes Industrial sector State-level non-fuel energy consumption estimates by fuel 

type by applying MECS-based non-fuel percentages to the SEDS total Industrial sector 

energy consumption estimates; 

 Subtracts Industrial and Commercial sector State-level distillate and LPG consumption 

estimates from a (forthcoming) NONROAD model run for 2002. 

 Converts the result of the steps above from their original units to the emission factor 

units; 

 Performs the point source subtractions using 2002 CENRAP point source inventory data 

and the ICI area source combustion SCC to point source SCC crosswalk; 

Template 2 – Apply Emission Factors – this workbook accompanies the discussion in Sections 

B.5 and B.6 of criteria pollutant and GHG emission factors and associated coal sulfur content 

assumptions. Reflecting the fact that some emission factors differ by type of coal, this template 

also estimates the proportion of Industrial and Commercial/Institutional coal that is anthracite 

versus bituminous/subbituminous in each State. This template will ultimately report the 

estimated sulfur content of coal consumed in each State. 

Template 3 – County Allocations – this workbook, which reflects the Section B.7 discussion, 

contains the data used to compute both sets of county allocation data (i.e., the county 

employment data and the total county energy consumption data). This template currently 

develops actual allocation data for Missouri counties. Ultimately, this template will only include 

county data for the allocation method that CENRAP chooses to implement in this project. This 

template also calculates county-level emissions from the Template 2 State-level emission 

estimates. 

Template 4 – Temporal Allocation – this workbook, which reflects the discussion in Section 

B.8, provides the data that will be used to allocate annual county emissions to monthly, average 

weekly, average weekday, and average weekend day time periods. It will ultimately perform the 

necessary calculations to estimate emissions in each period.

Appendix C-7 

Temporal Profile Documentation and Table 
Temporal Allocation of Annual Emissions to Ozone Season Day The procedures summarized in this appendix are based on the April 29, 2002 memorandum from Gregory Stella, U.S. EPA, “Temp

Emissions using EMCH Temporal Profiles.” Nonpoint emissions are calculated on an annual basis. They are then allocated to an a

season day emissions through the following calculation steps: The first step is to allocate annual emissions to a particular month. A monthly profile is selected based on the nonpoint Source Clasannual emissions are multiplied by the monthly weight factor from the profile divided by the total weight factor as follows: 

Monthly Emissions = Annual Emissions * (July Profile / Total Monthly Factor) 

Next, emissions for an average monthly day are estimated from the monthly total. Because the monthly profiles are not weighted fo

each month, an average day per year is used in the calculation as shown below: 

Average Day Emissions = Monthly Emissions/ (Days per Year/ Months per Year) 

Average Day Emissions = Monthly Emissions/ (365/12) 

The average day’s emissions value is then converted to a specific day of the week. A weekly profile is selected based on a SCC. Us

factor from the profile, emissions for this day are calculated with the following equation: 

Average Wednesday Emissions = Average Day Emissions * [(Tuesday Profile/ Total Weekly Factor) / (Average Day/Numb

Average Wednesday Emissions = Average Day Emissions * [(Tuesday Profile/ Total Weekly Factor) / (1/7)] 

Example: St. Louis City (29510) Area Source Fuel Combustion – Industrial Bituminous/Subbituminous Coal Combustion 

Annual Emissions of CO: 218.7 tons per year July Profile: Profile Number 262 includes July Profile 83 and Monthly factor 996 

Monthly emissions: 218.7 tons/year * (83/996) = 18.2 tons/ month 

Average July Day Emissions: 18.2 tons/month / (365/12) = 0.59 tons/average day Wednesday Profile: Profile Number 8 includes Tuesday Profile 147 and Weekly factor 1000 

Average July Wednesday emissions: 0.59 tons /avg day * (147/1000) / (1/7) = 0.59 * 1.029 = 0.61 tons/day

and assigns and upon all persons, contractors, and consultants acting under or for either 

the Department or MEMC or both. 

8. The parties agree to undertake all actions required of them by the terms and conditions of 

this Agreement. 

9 . Notwithstanding the terms of any contract, MEMC is responsible for compliance with 

this Agreement and for insuring that its contractors and agents comply with this

EPA and Department deadlines for compliance with the RACT regulations and other 

unforeseen requirements. Neither the State of Missouri nor any agency thereof shall be 

held out as a party of any contract entered into by MEMC in carrying out activities 

pursuant to this Agreement. 

FINDINGS OF FACT 

12. The Department's Air Pollution Control Program has made the following findings 

regarding the State's obligation to develop RACT regulations as part of the oxides of 

nitrogen (NOx) precursor fine particle (PM2.5) planning efforts for the St. Louis 

Nonattainment Area: 

The Department identified that MEMC plans to continue to operate the nitric acid etching 

stations with the current scrubbing systems collectively identified as Point 7/Point 7L, 

(Emission Unit 7 and 7L). In reviewing the information provided by MEMC, the 

Department has concluded that there are no additional cost effective control technologies 

for NOx because costs for these additional.controls ranged from $8,048 to $13,078 per 

ton reduction. 

2 
AGREEMENT AND COMPLIANCE PLAN 

13. The Department has detennined that the continued operation of the nitric acid etching 

stations small scrubbers identified by MEMC as Unit 7, N-120-2 for the first stage and N120-3 and N-120-4 in parallel as the second stage, (so all three operate); and identified by 

MEMC as Unit 7L with K-45-1 (or K-45-2) as the first stage and K-45-3 (or K-45-4) as 

. the second stage, (so both operate) meets the definition of RACT for the ~ual PM2.5 

effort at MEMC. If the nitric acid etching stations are shut down, the scrubbers are not 

required to be operated. This Department's consent agreement with MEMC will make 

this plan legally enforceable. The Department is going to include this agreement in 

Missouri's fonnal submittal to the U.S. Environmental Protection Agency (EPA) as part 

of Missouri's State Implementation Plan (SIP). 

CONCLUSIONS OF LAW 

14. MEMC is a person within the meaning of section 643.020 of the Revised St~tutes of 

Missouri (RSMo) .. 

15. Section 643.060.4, RSMo, provides that the Director of the Department is responsible fqr 

administering and enforcing the Missouri' Air Conservation Law, investigating 

complaints, issuing orders and taking all actions necessary to implement the Missouri Air 

Conservation Law. Section 643.06().2, RSMo. RSMo, provides that the Director is 

authorized to enter into contracts as he deems necessary for carrying out the provisions of· 

the Missouri Air ConserVation Law. In addition, the Missouri Air Conservation 

. Commission.is granted the legal authority under section 643.050, RSMo, to develop and 

implement regulations and enter into agreements to control air pollution. 

BEST PROFESSIONAL JUDGMENT 

16. The requirements of this Agreement represent the best professional judgment of the 

Department based on infonnation available as of the effective date of this Agreement. If 

circumstances change. significantly so that data related to the commitments of this 

Agreement indicates an imminent threat of danger to the public health, safety or the 

environment or if the Department detennines there is a significantly different threat other 

than the issues addressed herein, then the Department reserves the right to modify dates 

or requirements herein as it deems reasonably necessary to comply with the RACT 

regulations, provided that the Department gives MEMC at least 90 days notice and an 

opportunity to submit a compliance schedule after the 90 day notice period or submit 

written objections to the Department's detennination of a significantly different threat . 

.. MEMC shall submit either a compliance schedule or written objections to the Department 

within 30 days of its receipt of the Department's notice. MEMC further reserves the right 

to appeal any such modifications or additional requirements in accordance with 

paragraph 30. 

3 
FORCE MAJEURE, EXCUSABLE DELAY, MODIFICATION 

17. The following shall constitute the goveming terms for force majeure, excusable delay, 

and modification of the Agreement: 

A. MEMC shall perform the requirements under this Agreement within the time 

limits set forth herein unless the performance is prevented or delayed solely by 

events which constitute a force majeure. For purposes of this Agreement a force 

majeure is defined as any event beyond the control of MEMC which could not be 

overcome by due diligence and which delays or prevents performance by a date 

required by this Agreement. Such events do not include increased costs of 

performance. Any delay caused in whole or in part by action or inaction by 

municipal, state, or federal regulatory authorities or third parties unrelated to 

MEMC shall be considered a force majeure and shall not be deemed a violation of 

any obligation required by this Agreement. 

B. MEMC shall have the burden of proving all claims of force majeure. Failure to 

comply by reason of force majeure shall not be construed as a violation of this 

Agreement. 

C. MEMC shall notify the Department in writing within ten (10) days after becoming 

aware of an event which MEMC. knew or reasonably should have known 

constituted force majeure. Such notice shall estimate the anticipated length of 

delay, its cause, measures to be taken to minimize the delay, and an estimated 

timetable for implementation of these measures. Failure to comply with the· 

notice provision of this section may constitute a waiver of MEMC's right to assert 

a force majeure claim and may be grounds for the Department, at its sole 

discretion, to deny MEMC an extension of time for performance. 

D. Within ten (10) days of the receipt of written notice from MEMC of a force 

majeure event, the Department shall notify MEMC of the extent to which 

modifications to this Agreement are necessary. In the event that the Department 

and MEMC cannot agree that a force majeure event has occurred or if there is no 

agreement on the length of the extension, the dispute shall be resolved as set forth 

in paragraph 18. 

E. Any modifications to any provision of this Agreement shall not alter the schedule 

for performance or completion of other tasks required by this Agreement, unless 

specifically agreed to by the parties in writing and incorporated into this 

Agreement. 

F. This Agreement may be amended by mutual agreement of the Department and 

MEMC. Such amendments shall be in writing, shall have as their effective date 

the date on which they are signed by both parties and shall be incorporated into 

this Agreement. 

4 
DISPUTE RESOLUTION 

18. The parties recognize that a dispute may arise between them regarding implementation of 

the action to be taken as herein set forth or other terms or provisions of this Agreement. 

A. If such dispute arises, the parties will endeavor to settle it by informal 

negotiations between themselves. If the parties cannot resolve the issue 

informally within a reasonable period of time, either of the parties may notify the 

other in writing stating its position with regard to the dispute and the reasons 

therefore. A party re.ceivingsuch a. notice of dispute will respond in writing 

within ten (10) days stating its position. The Department or MEMe shall then 

have an additional ten (10) day period or such longer time as the parties agree to 

respond. If the parties are still unable to reach an agreement, the matter shall be 

referred to the Director of the Division of Environmental Quality, who shall 

decide the matter and provide a written statement of his decision which shall be 

incorporated into the Agreement 

B. This dispute resolution procedure shall not preclude any party from having direct 

recourse to court if otherwise available under Missouri law. 

OTHER CLAIMS AND PARTIES 

19. Nothing in this Agreement shall constitute or be construed as a release for any claim, 

cause of action or demand in law or equity against any person, firm, partnership, or 

corporation not a signatory to this Agreement for any liability it may have arising out of 

or relating in any way to this Agreement. 

EFFECTIVE DATE, TERMINATION 

20. This Agreement shall become effective when signed by the Director of the Department or 

his designee. . 

21. This Agreement will be terminated at such time that it is superseded by a future 

agreement, regulation, or other enforceable document that contains equivalent or more 

stringent emission limits. The Department will provide written notice to MEMe of said 

termination. Such notice shall not be unreasonably withheld. Nothing in this Agreement 

shall preclude MEMe from challenging the applicability of a future regulation or other 

enforceable document to which MEMe is not signatory. 

5 
VOID OR VOIDABLE PROVISIONS 

22. If a cOUli of competent jurisdiction finds that any part of this Agreement is void, 

voidable, illegal or unenforceable, then that part shall be severed from this Agreement but
