AREA SOURCE DEFINITION 

For emission inventory development purposes, the term “area sources” traditionally refers to stationary air pollutant emission sources 

that are not inventoried at the facility-level. While point sources are inventoried individually, area sources are typically inventoried at 

the county level (Introduction to Area Source Emission Inventory Development Volume III: Chapter 1)

1

. Sources such as gasoline 

stations and dry cleaning establishments are often treated as both point and area sources. The main reason they are not exclusively 

treated as point sources is that the effort required to gather data and estimate emissions for each individual facility is very great, while 

emissions per facility are generally small. For these sources, a cut-off point, typically based on annual emissions, usually defines the 

distinction between point and area. The Consolidated Emissions Reporting Rule (CERR) specifies reporting criteria air pollutant 

(CAP) thresholds for point and area sources, which vary depending on the pollutant and the attainment status of a county (see

http://www.epa.gov/ttn/chief/cerr/index.html).

Individual emissions sources are grouped with other like sources into source categories. These source categories are grouped in such a 

way that they can be estimated collectively using one methodology. Most area source categories do not have an analogue in the point 

source inventory. Commercial/consumer product use is such an example. The boundaries of the individual activities associated with 

these sources are often hard to determine or are, at best, arbitrary. Even within a point source facility, some activities occur that are 

more easily treated as area source emissions. Some emissions associated with surface coating operations such as equipment cleaning, 

for example, can be more practically estimated using area source methods even though other surface coating operations may be 

reported as part of the point source inventory.

METHODS FOR ESTIMATING AREA SOURCE ACTIVITY AND EMISSIONS 

Area source emissions are generally estimated by multiplying an emission factor by some known indicator or collective activity for 

each area source category at the county level. Several methodologies are available for estimating area source activity levels and 

emissions. For this 2007 area source inventory, estimates were derived by (1) treating area sources as point sources, (2) obtaining

county-level activity data, (3) apportioning national or statewide activity data to counties, (4) use of per capita emission factors, and 

(5) use of per employee emission factors. Each approach has distinct advantages and disadvantages as discussed below.

Small sources that would normally be treated as area sources may be handled as point sources for several reasons. First, county level 

activity data may not be readily determinable for certain source categories. Municipal landfills provide an example of this situation.

For some source categories, county activity estimates were available. For example, monthly wine production data for 2007 were

available by county from the Alcohol & Tobacco Tax and Trade Bureau, Department of Treasury. If county activity data were not 

available, Commonwealth totals were apportioned to counties using data for a surrogate of the emissions activity. For example, the 

quantity of highway gasoline consumed in the Commonwealth was apportioned to the county level on the basis of vehicle miles 

traveled per county. Residential, commercial, and industrial fuel combustion were other categories that were handled in this manner. 

The major drawbacks of this approach are that additional data and resources are needed to apportion activity levels to the local level, 

and accuracy is lost in the process. If Commonwealth level data were not available, then national data were used in a similar manner.

Sources in certain area source categories were not only numerous and diffuse, but were too difficult to inventory by any of the above 

procedures. As an example, solvent evaporation from consumer and commercial products such as waxes, aerosol products and 

window cleaners cannot be routinely determined by DEP. In addition, it would be resource-intensive to develop and implement a 

survey that would yield such information. Per capita or per employee emission factors are used to estimate emissions for these source 

categories. The use of per capita emission factors is based on the assumption that, for a given source category, emission activity can be 

reasonably associated with population. This assumption is valid over broad areas for certain categories such as Architectural Surface 

Coating and solvent evaporation from Consumer and Commercial Products.

For categories that rely on a per capita emission factor, county population estimates for 2007 were obtained from the U.S. Bureau of 

the Census. When emissions are calculated from per employee emission factors, county-level employment data for 2006 were 

obtained. Because county employment data for 2007 was not be available from the Bureau of the Census’ County Business Patterns

(CBP) until July 2009, data for the appropriate North American Industrial Classification System (NAICS) codes were obtained by E. 

H. Pechan & Associates from the 2006 CBP1. The Commonwealth-level employment data were obtained at the NAICS code level 

from the U.S. Bureau of Labor Statistics.2

In some cases, the Census does not report the employment value for a particular NAICS code/county combination because of 

confidentiality concerns. In these cases, the Census provides employment data as a range (e.g., between 20 and 99 employees). When 

a precise number of employees was not available from CBP, an initial estimate was developed based on the mid-point of the reported 

range (e.g., 60 employees was used for the 20 to 99 employment range). For a given NAICS code, the mid-point estimates were then 

adjusted up or down to yield the Commonwealth-level employment for that NAICS code as reported in the CBP. The adjustments 

were computed by first calculating the difference between the Commonwealth-level CBP employment and the total of the 

employment values for counties for which actual employment values were reported in the CBP. The resulting value represents 

employment for the counties for which the CBP reports an employment range value. This value was then divided by the sum of the 

mid-point employment estimates for the counties for which employment was reported as a range. The resulting ratio was multiplied by 

the mid-point estimates to yield the final county employment estimates. The calculation spreadsheets provide each of the steps used in 

this estimation procedure. National, State and County level employment data downloaded from US Census Bureau, mapping of 

employment flag letters reported by County Business Patterns to the range and midpoints of the range, and calculated final activity 

data using the employment midpoint and adjustment factor was performed by E.H. Pechan & Associates.

Control Efficiency (CE)

Control efficiency is the emission reduction percentage associated with a control device, process change or reformulation. Control 

efficiencies can vary widely by source within an area source category. Area source control efficiency values represent the weighted 

average control for the category.

Rule Penetration (RP) 

Because lower-emitting sources within a source category may not be covered by a regulation, it is important to reflect the extent to 

which total source category emissions are affected. Rule penetration represents the percentage of total source category emissions that 

are affected by a regulation.

 
8

Rule Effectiveness (RE)

Rule effectiveness is a factor used to adjust the control efficiency to account for failures and uncertainties that affect the actual 

performance of the control. For example, control equipment performance may be adversely affected by age of the equipment, lack of 

maintenance, or improper use. With the exception of Federal regulations, a default RE value of 80 percent was applied when 

information was not available to substantiate the true RE value1. An RE of 100 percent was applied to all Federal regulations that 

require national compliance.

The RE factor is applied to the estimated control efficiency in the calculation of emissions from a source. The formula for the 

application of CE, RP, and RE is displayed below:

Uncontrolled Emissions = 50 pounds per day

Control Efficiency = 90 percent

Rule Penetration = 60 percent

Rule Effectiveness = 80 percent

Controlled Emissions = Uncontrolled Emissions × (1 – CE/100 × RP/100 × RE/100)

Controlled Emissions = 50 × (1 – 0.9 × 0.6 × 0.8) = 50 × (1 – 0.432) = 28.4 pounds per day

An RE and/or RP value can substantially increase emission estimates when high control efficiencies are involved. For example, if RP 

was not applied in the above example (equivalent to a 100 percent RP assumption), then estimated emissions are:

Controlled Emissions = 50 × (1 – 0.9 × 0.8) = 50 × (1 – 0.72) = 14 pounds per day.

Point Source Subtractions 

Source categories can appear in both the area source and point source inventory. For example, emissions from large dry cleaning 

establishments may be included in the point source inventory, while emissions from smaller dry cleaners (below some specified 

cutoff) are included in the area source inventory. When a point source inventory and an area source inventory include emissions from 

the same process, the area source emission estimates are adjusted to avoid double counting. Although many area source categories 

(e.g., Architectural Surface Coating) do not have companion point source categories, there are many source categories in the area 

source inventory for which emissions are reported in the Pennsylvania point source inventory (see Table 1). For these source 

categories, point source emissions are subtracted from total emission estimates to yield area source emissions.

Ideally, this adjustment would occur in the area source emission calculation by subtracting point source emission activity 

(throughput) from total emission activity as shown below.

Area Source Activity  Total Activity  Point Source Activity 

However, the Pennsylvania point source inventory does not report throughput for most sources. Therefore, it was necessary to

calculate the point source subtractions using total and point source emission estimates as identified below.

Area Emissionsp  Total Emissionsp Point Source Emissionsp

where:

p = pollutant

Separate point source inventories were developed for Allegheny and Philadelphia counties and for all other counties. Except for 

ammonia and lead, the Allegheny inventory reports annual emissions for all pollutants included in the area source inventory. These 

pollutants are also missing from the Philadelphia County annual inventory. Unlike the Allegheny inventory, the Philadelphia County 

inventory does not report PM emissions on a filterable and condensable basis, but rather on a primary basis. The inventory for the 

remaining counties reports annual emissions for the same pollutants as the Philadelphia County inventory, with the exception of 

primary PM2.5 (PM25-PRI), which is not reported for the remaining counties. Given the different ways in which PM emissions are 

reported in the 2002 Pennsylvania point source inventory, it was necessary to develop PM emissions on a consistent basis to facilitate 

the point source subtractions. Therefore, for Allegheny County, Pechan summed the condensable and the filterable PM emissions to 

obtain PM10-PRI and PM25-PRI emission values for use in the point source subtractions.
10

To facilitate the point source subtractions, the annual emission records for all point SCCs associated with an area source category were 

summed to the county level. The county-level point source annual emissions were then subtracted from the area source category 

annual emissions using an area source category-to-point source category crosswalk developed for this project. Note that in keeping 

with EIIP guidance, when the resulting area source emission estimate was negative, the area source emission value was set to zero. 

The following presents an example of point source NOx emission subtraction calculations for the Commercial/Institutional 

Bituminous/Sub-bituminous Coal Combustion category (SCC 2103002000).

ADHESIVES AND SEALANTS (SCC 2460600000) 

Adhesives are formulated organic polymer compounds that adhere to, or form a bond between, one or more substrates. 

They are commonly referred to as cements, glues and pastes. Adhesives can be classified as water-based, solventbased, hot melts, or radiation curable. Sealants and caulking compounds are organic polymers used to fill or seal gaps 

between surfaces. The primary solvents used in formulating adhesives and sealants are aliphatic hydrocarbons and 

keytones.

County-level emissions were calculated using a per capita emission factor which was obtained from the Emission 

Inventory Improvement Program (EIIP)1and U.S. Bureau of the Census 2007 population data2. The emission factor 

represents pre-control emission rates. A CE of 8.3 percent3and an RP of 48.6 percent4 were applied to reflect the 

Federal Rule for consumer products. There are no point sources associated with this category.

Each county’s emissions are estimated per the sample calculations listed below.

AIRCRAFT COATING (SCC 2401075000) 

This source category includes aircraft building and repairing. The emissions were calculated using an employmentbased emission factor1

and employee data from NAICS code 3364XX. The number of employees in each county for 

2006 was collected by E.H. Pechan and Associates, who calculated the midpoints from any given ranges2. Each 

county’s emissions were estimated per the following sample calculations below. Point source emissions, where present, 

were subtracted from these emission estimates.

APPLIANCES (SCC 2401060000) 

The VOC emissions from this source category result from the evaporation of the solvent used in the coating process in 

the manufacture of electrical appliances such as refrigerators, freezers, laundry equipment, and electric house wares. 

Emissions for each county were estimated per the sample calculations below using an employment-based emission 

factor1and the number of 2006 employees in the NAICS codes 3352XX. . The number of Appliance employees was 

collected from U.S. Census Bureau’s County Business Patterns2by E. H. Pechan and Associates who calculated

ARCHITECTURAL SURFACE COATINGS (SCC 2401001000)

Architectural surface coatings are used by homeowners and painting contractors to coat the interior and exterior of 

buildings and other structures. The coatings are applied by spray, brush, or roller and dry or cure at ambient conditions. 

The VOC emissions from this source category result from the evaporation of the paint and cleanup solvents. 

Each county’s emissions were calculated using a per capita emission factor1and U.S. Bureau of the Census 2007 

county population data2. The Federal architectural surface coating regulations call for a 20 percent reduction in the 

solvent content of architectural surface coatings manufactured after September 1999, which reduction was accounted 

for in the development of the new per capita emission factor for states with AC rules (2.41 lbs VOC/person/year)1.

ASPHALT PAVING (2 SCCs)

SCC category’s emissions for 2461021000 (Cutback Asphalt) and 2461022000 (Emulsified Asphalt) were calculated 

by E.H. Pechan and Associates. The following documentation was prepared by E.H. Pechan and Associates with 

footnotes located at the end of this section:

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

a. Emulsified Asphalt

Asphalt cements thinned with water and an emulsifying agent are known as cutback 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.1Emissions 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. 

b. Cutback Asphalt

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. Cutback 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 
21

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 these source categories, the following SCCs were assigned:

The general approach to calculating emissions from emulsified asphalt and cutback asphalt paving is to multiply the 

estimated county-level emulsified asphalt usage by emission factors for VOCs. 

State-level emulsified asphalt and 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 

VMTST,y = total VMT (million miles) in entire State for roadway class y
22

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 on-road national emissions inventory.

c. Emission Factors

Emission factors for emulsified asphalt and 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 = emulsified 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.
23

e. Sample Calculation

VOC emissions from emulsified asphalt usage in Allegheny County, Pennsylvania:

From the 2008 Asphalt Usage Survey, the state of Pennsylvania used 69,671 tons of emulsified asphalt in 2008. The 

fraction of paved road VMT traveled in Allegheny County is 10,516.10 million miles divided by 104,400.2 million miles 

which equals 0.10073.

Asphalt Usage Allegheny = ((69,671 tons * 2000 lbs / 8.34 lbs/gal) / 42 gal/barrel) * 0.10073

Asphalt Usage Allegheny = 40,070.571 barrels

VOC Emissions Allegheny = (40,070.571 barrels * 9.2 lbs/barrel) / 2000 lbs/ton

VOC Emissions = 184.32 tons

AUTOMOTIVE AFTERMARKET PRODUCTS (SCC 2460400000) 

The EPA has divided automotive consumer products into two different major categories: (1) detailing products, and (2) 

maintenance and repair products. It is often difficult to distinguish the automotive aftermarket product subcategories 

and formulations for distinct product types because category descriptions and designations may overlap. In some cases 

varying formulations may be due to the product form. There are a large number of individual VOCs in these products, 

including HAPs.

County-level emissions were calculated using a per capita emission factor which was obtained from the Emission 

Inventory Improvement Program (EIIP)1and U.S. Bureau of the Census 2007 population data2. The emission factor 

represents pre-control emission rates. A CE of 8.97 percent3and an RP of 48.6 percent4 were applied to reflect the 

Federal Rule for consumer products. There are no point sources associated with this category.

Each county’s emissions are estimated per the sample calculations listed below.

AUTOMOTIVE REFINISHING (SCC 2401005000) 

Automotive refinishing is the painting of worn or damaged automobiles, light trucks, and other vehicles. The coating of 

new cars, however, is considered in the point source inventory, and therefore not included in this inventory. Countylevel emissions were calculated using a per capita emission factor which was obtained from the ERTAC Area 

Inventory Comparability Project solvent working group1and U.S. Bureau of the Census 2007 population data2. The 

automotive refinishing VOC emission factor is 0.5 lb/person.

BAKERIES (SCC 2302050000) 

Bakery emissions, primarily ethanol, result from yeast fermentation during the baking process of bread and bakery 

products. Ethanol is emitted through a vent with any combustion product gases. Relevant NAICS codes for bakeries 

are 311811 and 311812.

County-level VOC emissions were calculated using an employment-based emission factor and the number of NAICS 

code 311811 and 311812 employees in each county. The number of employees in each county for 2007 was obtained 

from County Business Patterns1 The Bakeries emission factor is 0.11 tons VOC/employee/year2. Point source 

emissions, where present, were subtracted from these emission estimates.

COATINGS AND RELATED PRODUCTS (SCC 2460500000) 

Aerosol spray paints and related products such as paint removers make up this consumer and commercial solvent 

product group. Other forms of coatings (besides aerosols) are not included in this group, but are included under 

architectural or industrial coatings, or auto body refinishing. Aerosols spray paints contain VOCs that function as both 

solvents and propellants. The most commonly used propellants in aerosol paints are propane, butane and isobutane. 

Paint removers are classified as either application removers or immersion removers. Solvents such as methanol, ethanol 

and isopropanol are also used to enhance the action of the paint remover. Methylene chloride (53 percent) and 

methanol (41 percent) account for the majority of paint-removing solvents consumed (Frost & Sulllivan, Inc., 1990).

County-level emissions were calculated using a per capita emission factor which was obtained from the Emission 

Inventory Improvement Program (EIIP)1and U.S. Bureau of the Census 2007 population data2. The emission factor 

represents pre-control emission rates. A CE of 0 percent3and an RP of 48.6 percent4 were applied to reflect the Federal 

Rule for consumer products. There are no point sources associated with this category.

Activity Data

Activity data was collected from the US Census Bureau’s county level population estimates for July 1, 2007.

1

Control Factors

No controls were assumed for this category. 

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. 

Sample Calculations

Emissions are calculated for each county using emission factors and activity as:

Ex,p = Ax × EFx,p

 

1 U.S. Department of Commerce, Bureau of the Census, “Population Estimates Program,” T1. Population Estimates 

[10] data Set: 2007 Population Estimates, available from http://www.census.gov/popest/counties/CO-EST2007-

01.html, accessed March 2009.
35

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, 2007 is 1,219,210

The emission factor for VOC is 0.01205 lb/person

EVOC= 1,219,210 people × 0.012056 lb VOC/ person

= 14,698.81 lb VOC or 7.3494 ton VOC

CONSTRUCTION DUST (3 SCCs: SCC 2311010000, SCC 2311020000, SCC 2311030000)

RESIDENTIAL CONSTRUCTION

Emissions from residential construction activity are a function of the acreage disturbed and volume of soil excavated 

for residential construction. Residential construction activity is developed from data obtained from the U.S. 

Department of Commerce (DOC)’s Bureau of the Census. The following documentation was prepared by E.H. Pechan 

and Associates with footnotes located at the end of this section:

Activity data:

There are two activity calculations performed 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. 
42

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 Units2gives 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 Permit3has 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. 

Basement soil removal

To calculate basement soil removal, 2007 Characteristics of New Houses4is 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 16,000 ft3per basement). An additional 10% is added for peripheral dirt bringing the total to 17,600 ft3per 

basement. 
43

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 

Construction

Apartments 0.11 tons PM10/acre-month 12 months

2-Unit Structures 0.032 tons PM10/acre-month 6 months

1-unit Structures with 

Basements

0.011 tons PM10/acre-month 6 months

0.059 tons PM10/1000 cubic 

yards

Regional variances in construction emissions are corrected using soil moisture level and silt content. 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 30-year average 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. 
44

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.5

The equation for PM10 emissions corrected for soil moisture and silt content 

is:

Corrected E Initial

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

Example Calculation: 

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

Emissions from non-residential construction activity are a function of the acreage disturbed for non-residential 

construction. The following documentation was prepared by E.H. Pechan and Associates with footnotes located at the

Activity Data: 

Annual Value of Construction Put in Place in the U.S1has the 2008 National Value of Non-residential 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:

1. 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.

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.
47

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 Index3lists costs of the 

construction industry from 1999-2007. 

2007 acres per $106= 1999 acres per $106x (1999 PPI / 2007 PPI) 

=2 acres/$106(132.9 / 204.3)

= 1.301 acres per $106

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.

To account for the soil moisture level, the PM10 emissions are weighted using the 30-year average 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.

ROAD CONSTRUCTION

Emissions from road construction activity are a function of the acreage disturbed for road construction. Road 

construction activity is developed from data obtained from the Federal Highway Administration (FHWA). 

The following documentation was prepared by E.H. Pechan and Associates with footnotes located at the end of this 

section:

Activity Data:

The Federal Highway Administration has Highway Statistics, Section IV - Highway Finance, Table SF-12A, State 

Highway Agency Capital Outlay1for 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
50

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 are 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:

Urban Areas, Collectors 1900 9.8

Rural Areas, Collectors 1900 7.9
51

Residential building starts2are 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.

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 and silt content. These correction 

parameters are applied to initial PM10 emissions from road construction to develop the final emissions inventory.

To account for the soil moisture level, the PM10 emissions are weighted using the 30-year average 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.

The equation for PM10 emissions corrected for soil moisture and silt content is:

where: Corrected EPM10 = PM10 emissions corrected for soil moisture and silt content,

DEGREASING (4 SCCs: SCC 2415360000, SCC 2415300000, SCC 2415230000, SCC 2415200000)

(Auto Repair (Cold Cleaning) SCC 2415360000, Manufacturing (Cold Cleaning) SCC 2415300000, Electronics 

(Vapor/In-Line) SCC 2415230000, Other (Vapor/In-Line) SCC 2415200000)

Surface cleaning, also known as “degreasing”, includes the solvent cleaning or conditioning of metal surfaces and parts, 

fabricated plastics, electronic and electrical components and other nonporous substrates. These cleaning processes are 

designed to remove foreign material, such as oils, grease, waxes and moisture, usually in the preparation for further 

treatment, such as painting, electroplating, galvanizing, anodizing or applying conversion coatings. Three basic types of 

surface cleaning operations are currently used: cold cleaning, vapor cleaning, and in-line or conveyorized cleaning, which 

can be either a cold or vapor cleaning process. VOC emission results from the evaporation of solvents used in these 

processes.

Cold cleaning is a batch process in which solvents are applied at room temperature or slightly heated. Parts are immersed 

in a solvent, usually mineral spirits. Parts too large for immersion may be sprayed or wiped with a solvent. The primary 

cold cleaning application is cleaning of tools or metal parts at service and automotive repair stations and manufacturing 

facilities. Cold cleaning may incorporate covers or freeboards to limit the evaporative loss of solvents.

In-line cleaners use automated load systems (typically conveyors) to maintain a continuous feed to the cleaning unit. 

These units use both cold and vapor-cleaning methods as described above, with the majority being halogenated solvent 

cleaning systems. These units are used for large-scale operations and are usually enclosed except to the conveyor inlet or 

exit. A common application of in-line cleaners is cleaning printed circuit boards for the electronic and electrical 

component industries.

The Emission Inventory Improvement Program (EIIP) developed the following population-based methods for estimating 

degreasing emissions.
54

Activity data was collected from the US Census Bureau’s county level population estimates for July 1, 2007.1Point 

source emissions, where present, were subtracted from these emission estimates.

FACTORY FINISHED WOOD (SCC 2401015000) 

The VOC emissions from this source category result from the evaporation of the solvent used in the gluing and coating 

process. The emissions for each county were calculated using an employment-based emission factor 1and employees 

numbers in NAICS codes 321XX2. The number of employees in each county was collected from County Business 

patterns and the adjusted employee numbers were prepared by Pechan & Associates using employment midpoint and 

adjustment factors for any ranges obtained. Point source emissions, where present, were subtracted from these emission 

estimates.

FIFRA-REGULATED PRODUCTS (SCC 2460800000) 

Pesticides defined by FIFRA include substances or mixtures that are used to prevent, destroy, repel, or mitigate pests, 

as well as substances used as plant regulators, defoliators, and desiccants. Consumer pesticides are used in the home 

and garden, as well as in commercial and governmental applications. Disinfectants and antimicrobial products are 

included. Household uses include pet care products, disinfectants and insecticides. All consumer and commercial 

pesticides contain VOCs. Aerosol and liquid sprays contain VOCs as solvents, usually ethanol and isobutane. 

Pesticides products can be grouped according to their target pest, but should also be grouped according to their form 

(solid, liquid or aerosol) when considering control measures.

County-level emissions were calculated using a per capita emission factor which was obtained from the Emission 

Inventory Improvement Program (EIIP)1and U.S. Bureau of the Census 2007 population data2. The emission factor 

represents pre-control emission rates. A CE of 20 percent3and an RP of 48.6 percent4 were applied to reflect the 

Federal Rule for consumer products. There are no point sources associated with this category.

FUEL COMBUSTION – COMMERCIAL/INSTITUTIONAL (7 SCCs: SCC 2103001000, SCC 2103002000,

SCC 2103004000, SCC 2103005000, SCC 2103006000, SCC 2103007000, SCC 2103011000)

Source Description and Classification

This sub-sector covers emissions from fuel combustion at stationary non-point sources within the 

commercial/institutional sector. These documentation and fuel combustion emissions were calculated by E. H. Pechan 

and Associates. References are listed at the end of the Fuel Combustion – Commercial/Institutional section. The 

following are the fuel types that will be included in the inventory for the commercial/institutional non-point source subsector: anthracite coal, bituminous/sub-bituminous coal, distillate oil, residual oil, natural gas, LPG, wood, and 

kerosene. Motor gasoline is not included as a non-point source because it is expected that all non-point gasoline 

combustion in this sector is included in the non-road inventory.

The approach to be used in calculating emissions for commercial/institutional fuel combustion is to first develop statelevel fuel consumption estimates, then to allocate these to the county-level, and then to multiply the resulting countylevel consumption estimates by appropriate emission factors.

Source Classification. The non-point SCCs associated with commercial/institutional fuel combustion are displayed in

Activity Data

Table 2 summarizes this sector’s non-point source activity data, units, and data source. Total state-level commercial 

sector energy consumption data are available from the Energy Information Administration (EIA)’s State Energy Data 

System (SEDS), and were used for most source categories (EIA, 2007a). However, as documented below, a number of 

adjustments were made to the SEDS data, and a separate EIA data source was used for distillate oil. Year 2006 SEDS 

data were used to estimate 2007 emissions because these were the latest year consumption data available at the time 

this work was performed in 2009.

Fuel-Specific Activity Data Adjustments

Coal - for commercial/institutional coal combustion, the SEDS data do not provide coal consumption estimates by type 

of coal (i.e., anthracite versus bituminous/sub-bituminous) and in some cases, CAP emission factors differ between the 

two. Because anthracite is mined in the eastern half of the Commonwealth, while bituminous is mined in the western 

half, the emission calculations assume that eastern counties burn anthracite coal while western counties burn 

bituminous coal.

Distillate Oil and LPG – the SEDS commercial/institutional sector distillate oil and LPG consumption data include 

consumption estimates for equipment that EPA includes in the non-road sector inventory. To avoid double-counting of 

LPG consumption, EPA ran the National Mobile Inventory Model (NMIM) for 2006 and calculated the national 

volume of non-road LPG consumption from commercial sector source categories. This estimate was then divided into 

the SEDS total industrial sector LPG consumption estimate to yield the proportion of total commercial/institutional 

sector LPG consumption attributable to the non-road sector in that year (approximately 18 percent). To estimate the 

volume of commercial/institutional sector LPG consumption that should not be included in the non-point source inventory EPA subtracted 18 percent from each state’s commercial sector LPG consumption estimate reported in SEDS.

To avoid double-counting of distillate oil consumption between the non-point and non-road sector emission 

inventories, EPA relied on a source other than SEDS to estimate consumption. The approach uses more detailed 

distillate oil consumption estimates reported in EIA’s Fuel Oil and Kerosene Sales, and assumptions from the 

regulatory impact analysis (RIA) for EPA’s non-road diesel emissions rulemaking (EIA, 2008b; EPA, 2003). Table 4 

displays the assumptions that were applied to the state-level distillate oil consumption estimates reported in Fuel Oil 

and Kerosene Sales to estimate total stationary source commercial/institutional sector consumption.

Point Source Energy Adjustment

Because the point source inventory also includes commercial/institutional fuel combustion source categories, it is 

necessary to subtract point source inventory fuel use from the SEDS fuel consumption estimates. Table 5 displays the 

crosswalk between commercial/institutional fuel combustion non-point SCCs and associated point SCCs that EPA 

plans to use in the subtraction procedure. The subtractions will be performed after summing the point source 

throughput estimates to the state-level.

County Allocation of State Activity Data

Year 2007 county-level activity estimates will be developed by allocating the state-level activity resulting from the adjustments to the 

SEDS data described above. The EPA compiled 2006 estimates of commercial sector (NAICS codes 42 through 81) employment 

from the Bureau of Census’ County Business Patterns 2006 for use in this procedure (Census, 2009a). A separate document describes 

how withheld County Business Patterns employment data were estimated (Divita, 2008). The EPA also developed 2006 county-level 

estimates of institutional sector (NAICS code 92) employment from 2007 local government employment data in the 2007 Census of 

Governments and adjustments reflecting each state’s 2006/2007 local government 

employment ratio (Census, 2009b).1 State-level commercial/institutional fuel combustion by fuel type was allocated to each county 

using the ratio of the number of commercial/institutional sector employees in each county to the total number of

The EPA has compiled criteria and hazardous air pollutant emission factors for non-point source commercial/institutional fuel 

combustion categories (Huntley, 2009). These emission factors, which are too numerous to list here, are included in a spreadsheet 

within the ICI fuel combustion workbook. In most cases, these are the same emission factors that were used in preparing the 2002 

non-point source NEI (Pechan, 2006). Commercial/institutional wood combustion emission factors were obtained from an ICI fuel 

combustion study being performed for the Central Regional Air Planning Association (CENRAP) (Pechan, 2009a).

Potential Improvements 

States may wish to incorporate the following improvements in developing non-point source commercial/institutional fuel combustion 

emission estimates: Update SO2 emission factors to reflect coal sulfur content estimates for coal used in the industrial sector in 2006--

a recent review of industrial and commercial coal sulfur content values for the Central Regional Air Planning Association concluded 

that the 2002 NEI values are based on unrepresentative data (Pechan, 2009b).1

Source Category Description

This sub-sector covers emissions from fuel combustion at stationary non-point sources within the industrial sector (i.e., sources that 

are not reported in the point source inventory because their emissions are too small). These documentation and fuel combustion 

emissions were calculated by E. H. Pechan and Associates. References are listed at the end of the Fuel Combustion – Industrial 

section. Industrial fuel combustion emissions will be computed for the following fuel types: coal, distillate oil, residual oil, natural 

gas, liquefied petroleum gas (LPG), kerosene, and wood.

There are additional types of energy that are consumed in the industrial sector: asphalt and road oil; feedstocks, naphtha (less than 

401°F); feedstocks, other oils (greater than 401°F); lubricants; motor gasoline; miscellaneous petroleum products; pentanes plus; 

special naphthas; and waxes. With the exception of motor gasoline, all of these additional fossil fuels are not actually combusted 

(oxidized) but are used as chemical feedstocks, construction materials, lubricants, solvents, or reducing agents. Therefore, there are no 

industrial sector combustion emissions from these fuel types. As described in more detail later, most of the fuel types that are 

included in the industrial combustion sector, also have a non-fuel use component. Therefore, it is necessary to exclude this component 

in calculating non-point source industrial fuel combustion activity/emissions. Motor gasoline is not inventoried as a non-point source 

because it is expected that gasoline combustion in this sector is included in the non-road inventory.

The approach to be used in calculating emissions for industrial fuel combustion is to first develop state-level fuel consumption 

estimates, then to allocate these to the county-level, and then to multiply the resulting county-level consumption estimates by 

appropriate emission factors.

Activity Data

Table 2 summarizes this sector’s non-point source activity data, units, and data source. Total state-level industrial sector energy 

consumption data are available from the Energy Information Administration (EIA)’s State Energy Data System (SEDS), and were 

used for most source categories (EIA, 2008a). However, as documented below, a number of adjustments were made to the SEDS 

data, and a separate EIA data source was used for distillate oil. Year 2006 SEDS data were used to estimate 2007 emissions because 

these were the latest year consumption data available at the time this work was performed in 2009

Fuel-Specific Activity Data Adjustments

Coal - for industrial coal combustion, it was necessary to compile data representing a sub-set of total sector coal consumption. Data 

representing non-coke plant consumption were compiled from EIA because coal consumed by coke plants is accounted for in the point 

source inventory. The SEDS data do not provide coal consumption estimates by type of coal (i.e., anthracite versus bituminous/subbituminous) and in some cases, CAP emission factors differ between the two. Because anthracite is mined in the eastern half of the 

Commonwealth, while bituminous is mined in the western half, the emission calculations assume that eastern counties burn anthracite 

coal while western counties burn bituminous coal.

Distillate Oil and LPG – the SEDS industrial sector distillate oil and LPG consumption data include consumption estimates for 

equipment that EPA includes in the non-road sector inventory. In particular, SEDS considers the following non-road source category 

activities to be part of the industrial sector: farming, logging, mining, and construction. To avoid double-counting of LPG 

consumption, EPA ran the National Mobile Inventory Model (NMIM) for 2006 and calculated the national volume of non-road LPG 

consumption from agriculture, logging, mining, and construction source categories. 

This estimate was then divided into the SEDS total industrial sector LPG consumption estimate to yield the proportion of total 

industrial sector LPG consumption attributable to the non-road sector in that year (approximately 9 percent). 

To estimate the volume of industrial sector LPG consumption that should not be included in the non-point source industrial fuel 

combustion category, EPA subtracted 9 percent from each state’s industrial sector LPG consumption estimate reported in SEDS.

To avoid double-counting of distillate oil consumption between the non-point and non-road sector emission inventories, EPA relied on 

a source other than SEDS to estimate consumption. The approach uses more detailed distillate oil consumption estimates reported in 

EIA’s Fuel Oil and Kerosene Sales, and assumptions used in the regulatory impact analysis (RIA) for EPA’s non-road diesel 

emissions rulemaking (EIA, 2008b; EPA, 2003). 

Table 4 displays the assumptions that were applied to the state-level distillate oil consumption estimates reported in Fuel Oil and 

Kerosene Sales to estimate total stationary source industrial sector consumption.

This value differs from the 0% assumption adopted in EPA’s non-road diesel emissions rulemaking because it is known that some diesel fuel is 

used by stationary sources (a 15 percent value was selected for use as an approximate mid-point of a potential range of 8 to 24% stationary 

source use computed from a review of data from the EIA’s Manufacturing Energy Consumption Survey and Fuel Oil and Kerosene Sales).

Non-Fuel Use Energy Adjustment

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 industrial 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 Greenhouse Gas Inventory Tool (SIT) provides 

national defaults representing the percentage of total industrial fuel consumption from non-energy uses. These default values have an 

additional limitation beyond their lack of geographic detail - they represent the EIA’s definition of the industrial sector, which 

includes fuel consumption from industrial, farm, mining, and construction sectors that is accounted for in the non-road inventory. 
92

Furthermore, a review of the SIT default data indicates that all residual oil is consumed as a fuel source. However, the EIA’s 2002 

Manufacturing Energy Consumption Survey (MECS) indicates significant non-fuel use of residual oil in the manufacturing sector 

(EIA, 2007a). In discussions about this issue, EIA noted that the non-fuel use data in the SIT appeared to be incorrect, and that the 

MECS data were representative of 2002 non-fuel use (Lorenz, 2009). Given this concern, a review was conducted of the non-fuel use 

assumptions incorporated into the EIA’s GHG emissions inventory for 2005 (EIA, 2007b). For each type of industrial sector energy 

consumed in 2006, Table 5 summarizes EIA’s non-fuel use assumptions.

Table 5. Non-Fuel Use Information from EIA’s 2005 GHG Inventory

Fuel Non-Fuel Use 

Assumption

Asphalt and Road Oil 100%

Coal (non-coke) Yes (<100%)

Distillate Oil Yes (<100%)

Feedstocks, Naphtha <401°F 100%

Motor Gasoline None

Natural Gas Yes (<100%)

Special Naphthas 100%

Waxes 100%

In calculating the emission activity for industrial fuel combustion, EPA excluded all SEDS fuel types for which EIA assumes 100 

percent of consumption is non-fuel use. 
93

For fuel types for which non-fuel use occurs, but is less than 100 percent, Pechan reviewed two information sources to identify the 

non-fuel use percentage to apply in the NEI. The first source was that listed by EIA in its 2005 national GHG inventory; the second 

was the EIA’s 2002 MECS. The MECS data has the advantage of providing region-specific estimates as well as values that exclude 

fuel consumption that is already accounted for in the non-road inventory. For distillate and residual fuel and natural gas, the EIA GHG 

inventory source was MECS. For LPG, it was not possible to use the EIA GHG inventory source for non-fuel consumption as it is a 

proprietary source published by the American Petroleum Institute. For non-coke coal, EIA extrapolated data from 1994. 

The MECS non-fuel consumption data treat coal that is used to produce coke as a feedstock, and therefore, MECS can not be used to 

represent non-coke coal consumption. The 2002 MECS data treat “synthetic coal” that is ultimately combusted as regular coal, as a 

non-fuel (feedstock) use. Because of the limitations of the MECS data, EPA obtained from EIA a rough estimate of the percentage of 

non-coking coal that is used for non-fuel purposes (while also treating “synthetic coal” as a fuel use). 

Based on the EIA’s estimate that 5-10 percent of non-coke coal is used for non-fuel purposes, EPA assumed that 7 percent of noncoke plant industrial sector coal consumption is for non-fuel purposes (Lorenz, 2009). Table 6 presents the non-fuel use percentages 

that were applied to estimate industrial fuel combustion activity.

Source Energy Adjustment

Because the point source inventory also includes industrial fuel combustion categories, it is necessary to subtract point source 

inventory fuel use from the SEDS fuel consumption estimates. 

Table 7 displays a crosswalk between industrial fuel combustion non-point SCCs and associated point SCCs that EPA plans to use in 

the subtraction procedure.1 The subtractions will be performed after summing the point source throughput estimates to the state-level.

County Allocation of State Activity Data

Year 2005 county-level activity estimates will be developed by allocating the state-level activity resulting from the adjustments to the 

EIA data described above. The EPA compiled 2006 estimates of manufacturing sector employment from the Bureau of Census’ 

County Business Patterns 2006 for use in this procedure (Census, 2009). State-level industrial fuel combustion by fuel type will be 

allocated to each county using the ratio of the number of manufacturing sector (NAICS codes 31-33) employees in each county to the 

total number of manufacturing sector employees in the state.

a Note that EIA’s SEDS includes natural gas used as pipeline fuel (e.g., for use in compressor engines) in the Transportation sector rather than the Industrial sector Therefore, such 

pipeline use should not be included in the point source subtraction procedure.

d. Emission Factors 

The EPA has compiled criteria and hazardous air pollutant emission factors for non-point source industrial fuel combustion categories 

(Huntley, 2009). These emission factors, which are too numerous to list here, are included in a spreadsheet within the ICI fuel 

combustion workbook. In most cases, these are the same emission factors that were used in preparing the 2002 non-point source NEI 

(Pechan, 2006). Industrial LPG and wood combustion emission factors were obtained from an ICI fuel combustion study being 

performed for the Central Regional Air Planning Association (CENRAP) (Pechan, 2009a).
100

Potential Improvements 

The following are potential improvements that states may wish to incorporate in developing non-point source industrial fuel 

combustion emission estimates:

 Investigate the availability of more geographic and year-specific estimates of non-fuel use consumption of industrial energy 

(e.g., MECS is planning to release 2006 year data in the coming months);

 Consider implementing a county allocation procedure that Pechan developed for the Central Regional Air Planning 

Association (CENRAP) that reflects the energy-intensity of each industrial sector--current methods only reflect number of 

employees in each industry sector (Pechan, 2009a); and

 Update SO2 emission factors to reflect coal sulfur content estimates for coal used in the industrial sector in 2006--a recent 

review of industrial coal sulfur content values for CENRAP concluded that the 2002 NEI values are based on unrepresentative 

data (Pechan, 2009b).

GASOLINE MARKETING (5 SCCs) 

(Stage I SCC 2501060053, Stage II Uncontrolled SCC 2501060101, Stage II Controlled SCC 2501060102, Underground Storage 

Tank Breathing and Emptying SCC 2501060201, Truck Transit SCC 2505030120)

Gasoline marketing involves the operations typically associated with transporting gasoline from refineries to final consumption in 

gasoline-powered vehicles. Evaporative emissions of VOCs occur at all points in the distribution process. The operations that were 

inventoried as area sources are gasoline dispensing outlets and gasoline tank trucks in transit. Bulk terminals and outlets are 

inventoried as point sources. VOC emissions result from the following sources: 1) Stage I (tank truck unloading into underground 

storage tanks), 2) Stage II (vehicle fueling), 3) Underground Storage Tank Breathing and Emptying, and 4) Truck Transit.

Each category’s emission factors were obtained from AP-42 Fire factors1. Throughputs were calculated from monthly data obtained 

from the Pennsylvania Department of Revenue Bureau of Motor Fuel Taxes2. County and state populations3 were used to apportion 

the gasoline throughput to each county. Control efficiency (CE)4,

Stage II:

Vehicle refueling VOC emissions were estimated using AP-42 factors, monthly gasoline sales estimates and county populations. 

These are the same gasoline sales figures that are used to estimate Stage I emissions.

Stage II control program information was included for the counties with controls based on program information regarding control 

efficiency from Pennsylvania. The Pennsylvania counties with Stage II controls are Allegheny, Armstrong, Beaver, Bucks, Butler, 

Chester, Delaware, Fayette, Montgomery, Philadelphia, Washington, and Westmoreland.

Population data were used to allocate monthly Pennsylvania gasoline sales to each county.

HOUSEHOLD PRODUCTS (SCC 2460200000) 

Household products consist primarily of cleaning products for hard surfaces, clothing, carpet, dishes waxes and polishes. Other 

products include air fresheners and charcoal lighter fluids. These products have air emissions such as special napthas, alcohols, 

carbonyls and other organics that contain VOCs. The amount of VOCs emitted primarily depends on the VOC content of the product 

and the amount of product used.

County-level emissions were calculated using a per capita emission factor which was obtained from the Emission Inventory 

Improvement Program (EIIP)

1

and U.S. Bureau of the Census 2007 population data2. The emission factor represents pre-control 

emission rates. A CE of 10.94 percent3and an RP of 48.6 percent4 were applied to reflect the Federal Rule for consumer products. 

There are no point sources associated with this category.

OPEN BURNING (3 CCs)

(Residential Household Waste SCC 2610030000; Residential Yard Waste – Leaves, SCC 2610000100; Residential Yard Waste -

Brush SCC 2610000400)

Open burning can be done in open drums or baskets, in fields and yards, and in large open dumps or pits. Materials commonly 

disposed of in this manner include household waste, landscape refuse, agricultural field refuse, wood refuse, and leaves. For emission 

inventory purposes, Open Burning is divided into four categories: Residential Household Waste; Residential Leaf; Residential Brush;

Land Clearing.

County-level emissions were calculated for Residential Household Waste using an emission factor which was obtained from the 

Emission Inventory Improvement Program (EIIP)1and U.S. Bureau of the Census 20002and 20073population data. There are no point 

sources associated with this category.

Throughput data was obtained from the percent Rural 2000 county population numbers applied to the 2007 county populations. The 

average household size4 was considered to be 2.5 residents and the average amount of waste produced per household4 was considered

Yard Wastes

Yard waste burning is the open burning of materials such as grass clippings, leaves, and trimmings from trees and shrubs. Yard waste 

burning takes place where the waste is generated (i.e., residences, parks, institutions such as universities or hospitals, office complexes 

or other areas where grounds maintenance generates this type of waste) or waste disposal sites where wastes have been collected. 

Many municipalities, who provide leaf removal and composting, prohibit or restrict the burning of yard wastes. 

County-level emissions were calculated for the Open Burning categories of Residential Yard Waste - Leaves and Residential Yard 

Waste - Brush using emission factors obtained from AP-42 factors1, 1995.

Throughput data was obtained by applying the percent Rural 2000 county population2to the 2007 county populations3. The average 

amount of leaf waste produced per person1 was considered to be 0.64 lbs/day or 0.00728 tpy calculated for the months of September,

Activity data for the 2002 and 2010 inventories were developed using EPA’s Non-road Model which uses a variety of variables like 

equipment size, equipment population, equipment age, RVP, and air temperature to estimate activity. 

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. 

Section 2.2 of the EPA PFC report details emission factors used for each of the activities associated with PFCs. 

Emissions are calculated in the formula:

EmisCounty, Pollutant = m x yeardiff + Emis2002

where:

m = (Emis2010 – Emis2002) / (2010 – 2002)
137

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

RESIDENTIAL COAL FOSSIL FUEL COMBUSTION (2 SCCs: SCC 2104001000, SCC 2104002000)

Residential Coal Combustion is coal that is burned to heat residential housing. 

These documentation and fuel combustion emissions were calculated by E. H. Pechan and Associates. References are listed at the end 

of the Residential Coal Fossil Fuel Combustion section. The general approach to calculating emissions for these two SCCs is to take 

state coal consumption values 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:

Types

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 2007 emissions because year 2006 data were the latest data available when this 

inventory was prepared.

Fuel-Specific Activity Data Adjustments

Coal - for residential coal combustion, the EIA data do not distinguish between anthracite and bituminous coal consumption estimates.

(i.e., anthracite versus bituminous/sub-bituminous) Because anthracite is mined in the eastern half of the Commonwealth, while 
143

bituminous is mined in the western half, the emission calculations assume that eastern counties burn anthracite coal while western 

counties burn bituminous coal.

State-level coal consumption was allocated to each county using the US Census Bureau’s 2000 Census Detailed Housing 

Information.3These 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 Anthracite or Bituminous coalburning county to the total number of Anthracite or Bituminous coal-burning housing units in the State.

No controls were assumed for this category

Emission Factors

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.4This 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 Pennsylvania.

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-42.5Table 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).

Sample Calculations

Annual emissions are calculated for each county using emission factors and activity as:

Ex,p = FCx × EFx,p
144

where:

Ex,p = annual emissions for fuel type x and pollutant p (lbs/year),

FCx = annual fuel consumption for fuel type x,

EFx,p = emission factor for fuel type x and pollutant p.

County level fuel consumption is calculated using:

FCx = AState x RatioCounty houses

where: 

AState = total tons of coal reported by the EIA, 

RatioCounty houses = county allocation ratio based on number of houses burning coal per Anthracite coal-burning counties or per 

Bituminous coal-burning counties. 

Example:

Using Allegheny County, PA as an example:

Allegheny County, PA, labeled a Bituminous coal-burning county, had 183 houses out of the state total of 19,921 Bituminous coalburning houses that use coal as the primary heating fuel. This equates to a share of 0.9186 % of the 9,687.54 tons of coal used for 

residential heating in the state.

The emission factor for PM2.5-FIL Bituminous (See Table 2) is 3.8 lb/ton of coal burnt 

FCAllegheny, anth = 9,687.54 × 0.9186% = 88.9897 tons Bituminous coal

EmisAllegheny, anth, PM2.5-FIL = 88.9897 tons Bituminous coal × 3.8 lbs PM2.5-FIL per ton coal

= 338.1610 lbs PM2.5-FIL

RESIDENTIAL FUEL OIL/KEROSENE COMBUSTION (2 SCCs: SCC 2104004000, SCC 2104011000) 

Distillate oil and kerosene combustion sources emit VOC, NOx, CO, SO2, Pb, and PM. Fuel oil and kerosene emissions were 

calculated for each county using fuel use estimates derived by allocating Commonwealth consumption estimates from the Energy 

Information Administration to individual counties. The county allocations were performed using data obtained from the American 

Community Survey and the U.S. Census Bureau. 

 

SAMPLE CALCULATIONS:

Residential Distillate Fuel Oil/Kerosene:

Residential fuel oil and kerosene usage was determined by allocating the residential fuel oil and kerosene use to each county. The 

residential fuel consumption was allocated by the ratio of dwelling units (DU) using distillate fuel oil/kerosene in a county to the 

number of dwelling units burning distillate fuel oil/kerosene in the Commonwealth. The following is the general equation for the 

calculation of usage for residential sources of fuel oil and kerosene combustion.

Since the 2005-2007 American Community Survey did not include the six small populated counties in Pennsylvania (namely 

Cameron, Forest, Fulton, Montour, Potter and Sullivan counties) in their estimations of Occupied House Heating Fuel Units, these 

omissions were accounted for by taking the ratio of 2005-7 Averaged Total County Fuel Oil/Kerosene Heated Housing Units (not 

including the 6 Small Counties) to the 2007 Total State Housing Units (minus the 6 Small Counties' Housing Units) and by that

TRAFFIC LINE PAINTING (SCC 2401008000) 

Traffic paints are used to mark pavement in applications such as dividing lines for traffic lanes, parking space markings, crosswalks, 

and arrows. The markings are usually applied by Commonwealth or local highway maintenance crews. VOC emissions result from the 

evaporation of organic solvents during and shortly after application of the marking paint.

Each county’s emissions were calculated by using county-level lane miles totals1and a lbs VOC/lane mile emission factor2. 

There are no point sources associated with this category.

WINERIES (SCC 2302070005)

Winery emissions result from the entrainment of ethanol by carbon dioxide during wine fermentation. Factors affecting ethanol

emissions are handling techniques, temperature, process equipment design, and fermenting parameters. Other sources of emissions 

from the wine making process are blending, transferring, racking and storing of the wine.

Emissions were determined using 2007 county-level wine production data provided by the U.S. Department of the Treasury, Alcohol 

and Tobacco Tax and Trade Bureau.1 Because monthly production data were available, these data were used to develop the seasonal 

allocation factors for this category. The emission factors for both red and white wines were obtained from AP-42.2

Since the emission factors for the two types of wines are different, but wine type production data are not available, wine production in 

the Commonwealth was assumed to be 60 percent white wine and 40 percent red wine. Point source emissions, where present, were 

subtracted from these emission estimates. Each county’s emissions were estimated per the following sample calculations.

SAMPLE VOC EMISSION CALCULATIONS:

Annual VOC Emissions = (0.6  White Wine Emission Factor + 0.4  Red Wine Emission Factor)  (2007 Total Wine Production)

WOOD FURNITURE AND FIXTURES (SCC 2401020000) 

This source category includes establishments engaged in the manufacture of wood home or office furniture. VOC emissions result 

from the evaporation of solvents used in the finish coats and cleanup procedures. Point source emissions, where present, were

subtracted from these emission estimates. Each county’s emissions were calculated according to the sample calculations below using a 

per employee emission factor1and the number of employees in NAICS codes 337110, 337121, 337122, 337219, 337211, 337212 and
