110(a)(1) Maintenance Plan for 8-hour Ozone April 13, 2011 

1.0 INTRODUCTION AND SCOPE 

As a requirement of the 1997 8-hour ozone standard implementation rule, areas that were 

maintenance for the 1-hour ozone standard and designated as attainment for the 1997 8-hour 

ozone standard have to submit a 110(a)(1) maintenance plan within 3 years from being 

designated as attainment. The Triad area falls into this requirement. The 1-hour nonattainment 

area consisted of Davidson, Forsyth and Guilford Counties and a small portion of Davie County. 

The point source inventory consists of emissions from individual facilities. Primarily, these are 

industrial or commercial facilities that must have permits issued by the North Carolina Division 

of Air Quality (NCDAQ) and the Forsyth County Environmental Affairs Department. 

Although both the State and County agencies inventory all the criteria pollutants and a large 

number of toxic pollutants, only the nitrogen oxides (NOx) and Volatile organic compounds 

(VOCs) are reported here since they are the precursor pollutants for ozone formation. The years 

used for the comparison must include a base year (2007), at least one interim year (2011), and a 

future year (2018). The emissions comparison will be done for a typical ozone season day. 

2.0 OVERALL METHODOLOGY 

All large permitted sources are required to report emissions annually and every five years in the 

case of smaller sources to the NCDAQ. Additionally, the U.S. Environmental Protection 

Agency (USEPA) requires the NCDAQ to submit annually this data for large stationary point 

sources to them. The NCDAQ used the 2007 point source inventory as the base year emission 

inventory. For the smaller sources that report emissions every five years, the most recent 

emissions inventory available was used. This data was projected to 2011 and 2018. The 

emissions data upon which this document is based were from files maintained by the NCDAQ 

and Forsyth County Environmental Affairs Department.. 

2.1 Source Identification 

All facilities that have a potential to emit more than five tons per year of any criteria pollutant are 

required to have an air permit to operate. These sources are required to submit emission 

inventories to the NCDAQ. The local program in Forsyth County provided their county specific 

point source emissions inventory for 2007 to the NCDAQ.

110(a)(1) Maintenance Plan for 8-hour Ozone April 13, 2011 

2.2 Emission Estimation Approach 

The emission inventory information reported to the NCDAQ was transferred to a state developed 

emissions inventory program that helps ensure required data elements are not omitted. It also 

performs some calculations, thereby minimizing the occurrence of errors. Depending on the 

particular process and facility, emissions may be calculated by various means. In many cases, 

emissions are estimated using emission factors published in the USEPA’s AP-42, Compilation of 

Air Pollutant Emission Factors. In a relatively few cases, locally produced emission factors may 

be used. Sometimes, a mass balance calculation can be employed. In some cases, there is direct 

continuous monitoring (CEM) of emissions that are reported. 

Annual emissions are reported in the National Emission Inventory and maintained by the 

NCDAQ and Forsyth County Environmental Affairs Department. There is also data for seasonal 

percentage of emissions occurring in the summer quarter. Using this information, a typical 

summer daily emissions were calculated in tons per day. 

2.3 Emission Projection 

The most recently available emissions data was used as the baseline for the projected emissions 

in this report. Where available, the 2007 data was used (i.e., from major sources that are 

required to report emissions annually). The NCDAQ calculated linear regressions of future 

emissions by using the past five years (2003 -2007) of emissions data from North Carolina 

Criteria and Toxic Air Pollutant Point Source Emissions Report. The values were used to 

calculate growth factors to project point source emissions inventory to 2011, 2018. 

The NCDAQ considered recent projections for three key sectors in North Carolina where 

declining production was anticipated – SIC 22xx Textile Mill Products, 23xx Apparel and Other 

Fabrics, and 25xx Furniture and Fixtures. Figure 1 represents quarterly (seasonally adjusted) 

furniture manufacturing SIC 25 employment in the State of North Carolina. A predicted 

employment linear trend is estimated and an emission growth factor is calculated, where the 

predicted employment in 1999 is indexed to equal one. This declining growth slope represents a 

1.4% annual reduction. Although the NCDAQ has data that shows a steady decline in these 

industries in North Carolina, for the future year emission inventory projection the NCDAQ 

decided to use a growth factor of 1.0 for these SIC codes. The NCDAQ decided to maintain the 

emissions at 2007 levels as a conservative estimation of the future year emissions. The Triad 

areas have many of the three industries and the NCDAQ decided to hold emission at the 2007 

emission.

2.4 Future Emission Reductions 

The North Carolina Clean Smokestacks Act requires coal-fired power plants achieve a 77 

percent reduction of NOx emissions by 2009 and more than 70 percent reduction of SO2

emissions by 2013. The public utilities have committed to install scrubbers to reduce SO2 and 

selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) to reduce NOx. 

SCR can achieve control efficiency of 90 percent when removing NOx at coal-fired plants, 80 

percent when removing NOx at gas-fired plants. SNCR can achieve reductions of 35 percent 

when used for NOx controls. Although There is no affected source within the nonattainment 

areas, The Triad areas will also benefit from NOx reductions required at other large electrical 

generation facilities subject to the Clean Smokestacks Act that are located nearby but not in the 

nonattainment areas. 

3.0 QUALITY ASSURANCE 

The emission inventory has undergone a number of quality assurance checks so that it meets the 

standards for submitting the annual inventory to the USEPA. The state emissions inventory 

database program helps insure that important data elements are present. Where the program 

performs calculations, it helps avoid calculation errors. In addition, since the State began 
Point Source Emissions Inventory Documentation 4 

Greensboro-Winston-Salem, High Point area Appendix B.1 

110(a)(1) Maintenance Plan for 8-hour Ozone April 13, 2011 

collecting annual fees for emissions from Title V sources, both the State and the sources are 

careful that the tons-per-year emissions reported are accurate. 

4.0 POINT SOURCES EMISSIONS FOR TRIAD NONATTAINMENT AREA 

In the following sections the emissions for the Triad maintenance area are totaled, as well as, the 

estimated facility emissions for each county in the maintenance area are identified for the base 

year (2007) and the future maintenance years (2011, 2018). 

Emission summary tables for Triad maintenance counties are as follow:

5.0 DISCUSSION OF POINT SOURCE CATEGORIES 

Industrial processes in the inventory are identified with 8-digit numbers known as the Source 

Classification Codes (SCC). These are grouped numerically into a number of categories for 

convenience. The following is the inventories reported by SCC by county. In general, the first 

three digits of the SCC code describe the process and the last five digits give more detail as to 

the fuel used, size of source, etc. 

It should be remembered that the SCC in any particular instance was selected by an individual 

entering inventory data into a computer maintained record. It may be that in some cases, other 

individuals would have selected other codes. In some cases, there are two or three parallel codes 

that describe the same sort of equipment, the difference being size. In other cases, one is able to 

select a general code for an overall process or use several more specific codes that together 

would be covered by the more general one. If, upon consideration, it appears that a more 
Point Source Emissions Inventory Documentation 5 

Greensboro-Winston-Salem, High Point area Appendix B.1 

110(a)(1) Maintenance Plan for 8-hour Ozone April 13, 2011 

appropriate code could have been selected, that does not mean that the reported emissions are 

inaccurate. 

A listing of SCC with descriptions may be found in FIRE Version 5.0 Source Classification 

Codes and Emission Factor Listing for Criteria Air Pollutants, EPA-454/R-95-012. 

Occasionally, new SCC is defined so it may be useful to search the EPA’s website for new 

entries. 

5.1 External Combustion Boilers 

Table 5.1-1 tabulates the emissions for the SCC codes 1-01-xxx-xx, boilers for electrical 

generation. The emissions for SCC codes 1-02-xxx-xx, industrial boilers, are tabulated in 

Table 5.1-2. The emissions from commercial and institutional boilers, SCC codes 1-03-xxx-xx, 

are tabulated in Table 5.1-3.

5.3 Industrial Processes 

There are a large number of SCC codes under the heading of industrial processes. The 

emissions from chemical manufacturing, SCC 3-01-xxx-xx, are tabulated in Table 5.3-1. The 

emissions from food and agriculture, SCC 3-02-xxx-xx, are summarized in Table 5.3-2. 

Secondary metal production processes, SCC 3-04-xxx-xx, emit NOx and VOC from fuel 

combustion in order to melt or heat metals for forming into various items. The emissions from 

these SCCs are summarized in Table 5.3-3. Mineral products processes, SCC 3-05-xxx-xx, 

generate NOx and VOC emissions typically from fuel combustion in order to operate kilns. The 

emissions from these SCCs are compiled in Table 5.3-4. Final Textile Products, SCC 3-30-xxxxx, generate VOC emission from Industrial Processes are summarized in Table 5.3-5.

1.0 INTRODUCTION AND SCOPE 

Area sources represent a collection of many small, unidentified points of air pollution emissions 

within a specified geographical area, emitting less than the minimum level prescribed for point 

sources. Because these sources are too small and/or too numerous to be surveyed and 

characterized individually, all area source activities are collectively estimated. The county is the 

geographic area for which emissions from area sources are compiled, primarily because counties 

are the smallest areas for which data used for estimating emissions is readily available. 

The area sources emissions inventory has been developed in order to meet the requirement of the 

1997 8-hour ozone standard implementation rule, which states that areas that were maintenance 

for the 1-hour ozone standard have to submit a 110(a)(1) maintenance plan within 3-years of 

being designated as attainment. The Greensboro/Winston-Salem/High Point, North Carolina 

1-hour maintenance area, referred to as the Triad area, meets the conditions that require a 

110(a)(1) maintenance plan. The Triad area includes Davidson, Forsyth, and Guilford Counties 

and part of Davie County. For the purpose of this maintenance plan, emissions are estimated for 

all of Davie County. All emissions are calculated on a ton per summer day basis. 

2.0 OVERALL METHODOLOGY 

2.1 SOURCE CATEGORY IDENTIFICATION 

The area source categories were identified from two U. S. Environmental Protection Agency 

(USEPA) guidance documents: EPA-450/4-91-016, Procedures for the Preparation of Emission 

Inventories of Carbon Monoxide and Precursors of Ozone, Vol. 1, hereafter Procedures, and the 

Emissions Inventory Improvement Program (EIIP) Technical Reports, Vol. 3, Area Sources1

 as 

of December 2002 (the most current version at the time of the inventory development), hereafter 

EIIP Tech. Report. 

2.2 EMISSION ESTIMATION APPROACH 

Area source emissions are estimated by multiplying an emission factor by some known indicator 

of collective activity for each source category within the inventory area. An indicator is any 

parameter associated with the activity level of a source that can be correlated with the air 

pollutant emissions from that source, such as production, number of employees, or population. 

In general, one of the following emissions estimation approaches is used to calculate the area 

source emissions: per capita emission factors, employment-related emission factors, commodity 
Area Source Emissions Inventory Documentation 

Greensboro-Winston-Salem, High Point area Appendix B.2 

110(a)(1) Maintenance Plan for 8-hour Ozone April 13, 2011

consumption-related emission factors, and level of activity based emission factors. The emission 

factors used were obtained from the EIIP Tech. Report, the USEPA’s AP-42 Compilation of Air 

Pollutant Emission Factors, 5th Edition, referred to as AP-42 or the methodologies outlined by 

E.H. Pechan & Associates, Inc. based on the ongoing emission factor development work 

conducted by the Eastern Regional Technical Advisory Group (ERTAC) in conjunction with the 

USEPA. 

There are several methods for estimating the activity level for a specific area source category. 

These are: treating area sources as point sources, surveying local activity levels, apportioning 

national or statewide activity totals to local inventory areas, or using population and employment 

data. All of these methods were used to estimate the area source emissions. The base year for 

the emissions inventory is 2007, the interim year is 2011 and the future year is 2018. 

Many of the categories for the area source emissions use population and employment for the 

activity data. The 2007 population data was obtained from the North Carolina Office of State 

and Budget Management. The projected population for the interim year, 2011, and the future 

year, 2018, was also obtained from the North Carolina Office of State and Budget Management. 

Table 2.2-1 contains the 2007 population for the Triad maintenance area for 2007, 2011 and 

2018.

Guilford 459,199 490,771 542,623 

For creating projected future year emissions for many source categories, the emissions 

estimations are based on population. The population growth factors are developed based on the 

ratio of the base year (2007) population to the future years (2011 and 2018) population, see 

equation 2.2-1. 

Population Growth Factors = FYpop 2.2-1

where: 

BYpop = 2007 population per county 

 FYpop = future year population per county 

These growth factors are listed in Table 2.2-2.

Certain emission categories were adjusted for such things as season or rule effectiveness and rule 

penetration. These are discussed in the particular source categories descriptions. 

For certain categories, there can be overlap between the point source emissions and the area 

source emissions calculated with emission factors. The 2007 point source emissions in these 

categories were identified so that they could be subtracted where appropriate. 

There are a number of categories where emissions were calculated with emission factors based 

on employment. These emission factors were developed by the USEPA when employment 

statistics were organized by Standard Industrial Classification (SIC) code. However, since 1997, 

employment statistics are organized by the North American Industry Classification System 

(NAICS). For the solvent cleaning industries, the SIC codes do not directly correspond to single 

NAICS code. Sometimes several partial NAICS employment values will relate to a SIC code. A 

crosswalk was used to determine what percentage of a NAICS employment value would 

correspond to the SIC codes. It should be noted that the crosswalk is based on national totals and 

is not specific to any particular state. 

The employment numbers were obtained from the on-line 2007 County Business Patterns for the 

various NAICS codes at the county level for North Carolina. In addition to having employment 

values (or employment ranges due to confidentiality rules) by NAICS, the County Business 

Patterns breaks down the number of facilities by employment categories. The employment

categories are 1 – 4, 5 – 9, 10 – 19, 20 – 49, 50 – 99, 100 – 249, 250 – 499, 500 – 999, >1000 

employees. To account for point sources, it was assumed that facilities with 100 employees or 

greater were point sources and were not considered in the calculations. 

When a NAICS category gave a number of employees and there were no establishments with 

100 employees or greater, then the value was used, however, in most cases the US Census 

Bureau, County Business Patterns gave a range of total employees in the county instead of the 

actual number. When this occurred, facility sizes were considered and the mid-range of 

employees was assumed, in accordance with the EIIP Tech. Report. For example, a NAICS 

category for a county had a range of employment of 100-249 with two establishments with 1-4 

employees, one with 20-49 employees, and one with 100-249 employees. Assuming 3 to be the 

mid-range of 1-4 and 35 to be the mid-range of 20-49, the employment used for the area source 

calculation was estimated as: 

(2 x 3) + (1 x 35) = 41 employees 

The larger establishment was assumed to be a point source and not taken into consideration for 

the area source calculation. 

If a total number of employees was provided and there were establishments with 100 employees 

or greater, then the mid-range of the smaller facilities were used as described above. The 

estimated employment was compared to the value given to ensure that the remainder would 

account for the large establishment. In cases where the remainder would not be enough 

employment to account for the larger establishment, the area source employment was adjusted 

down. For example, a NAICS category had 250 employees with one establishment with 20–49 

employees (mid-range 35), two establishments with 50–99 employees (mid-range 75), and one 

establishment with 100–249 employees. The employment estimated for the area source and the 

remainder employment was estimated as: 

 (1 x 35) + (2 x 75) = 185 employees 

 250 – 185 = 65 employees 

The remainder of 65 employees is not enough to account for an establishment of 100–249 

employees. Therefore, the area source employment was adjusted down by 35 so that there were 

100 employees remaining to account for the large establishment.

3.0 QUALITY ASSURANCE MEASURES 

The first step in the quality assurance process is to develop a list of area sources applicable to the 

maintenance area. The Procedures document and the EIIP Tech. Report were the primary 

references used in preparing this list for the emissions inventory. Next, measures to ensure valid 

emission estimates were employed were verified using the guidance provided by the document 

EPA-450/4-88-023, the EPA Quality Assurance Document for Post-1987 SIP Emission 

Inventories. Since many of the emission estimates are based on the emission factors provided in 

the AP-42, the Procedures document or the EIIP Tech. Report, sources of error would primarily 

be associated with the emission factors and the accuracy of the emission calculations. 

Under the direction of the quality assurance coordinator, emission sources whose contribution 

was either at the high or low end of the range of estimates were scrutinized more closely for 

reasonableness. The accuracy was addressed by performing independent checks of the emissions 

calculations, verifying the activity data and emission factors as well as plotting all of the area 

source categories vs. pollutants. 

4.0 DISCUSSION OF AREA SOURCE CATEGORIES 

There are five major area source categories comprised of a number of individual types of area 

sources. Sections 4.1 through 4.5 addresses each of these categories and include a number of 

subsections that correspond to the corresponding category. The objective of each subsection is 

to describe each category and the emission estimation and/or projection procedures. 

4.1 GASOLINE DISTRIBUTION 

The area source emissions attributed to this category are associated with various operations 

related to gasoline and aircraft fuel handling and distribution. Since tank farms and bulk plants 

are specifically addressed in the point source inventory, the area source category is limited to 

fuel handling, storage, and distribution operations associated with the service stations and in the 

refueling of aircrafts. 

4.1.1 Gasoline Dispensing Facilities 

Since service stations are so numerous, they are collectively considered as an area source. The 

area source emissions that are derived for this subsection involve determining the estimated 

emissions that occur at each of the following operations: 1) losses during storage tank filling, 

2) storage tank breathing and working losses and 3) truck transit losses. The emissions from

vehicle refueling are captured in the on-road mobile source emissions inventory and therefore are 

not estimated as part of the area sources inventory. 

As part of the air toxics program, Stage I controls for gasoline dispensing facilities was adopted 

by the State, effective May 1990 with final compliance by January 1, 1994. Stage I is the vapor 

recovery technology on the underground storage tanks and reduces the emissions during the tank 

filling operations at service stations. 

The North Carolina Department of Agriculture, Standards Division is responsible for going to all 

gasoline dispensing facilities and testing the fuels to ensure that it meets the quality standards of 

the State. The North Carolina Division of Air Quality (NCDAQ) has worked out an agreement 

with the Standards Division to also check for Stage I controls. A notice is sent to the NCDAQ 

for every facility checked by the Standards Division verifying if a facility has properly 

maintained control equipment. If a facility is found to not be properly maintaining the control 

equipment, then the NCDAQ sends a notice of violation informing the facility that the controls 

are required and gives the facility time to correct the violation before fines are accessed. From 

this information the rule effectiveness and rule penetration can be estimated. The rule 

effectiveness is the percentage of facilities complying with the rule and the rule penetration is the 

percentage of facilities requiring Stage I controls. Control efficiency is the expected percent 

reduction from this control technology. The compliance and rule effectiveness rates for Stage I 

controls for the Triad maintenance area were obtained from the Winston-Salem region Stage I 

vapor recovery reports supplied by the Mobile Sources Compliance Branch, North Carolina 

Division of Air Quality. The control efficiency rate, 0.95, is a conservative estimate used for the 

entire State. The Stage I compliance factors are listed in Table 4.1.1-1.

Delivery to Outlets-Underground Storage Tanks-Stage I Balanced Submerged Filling Stage I 

controls capture the displacement of gasoline vapors from the storage tanks during the transfer of 

gasoline from tank trucks to storage tanks at the service station. The emissions calculation was 

obtained from EIIP Tech. Report, Chapter 11-Gasoline Marketing, equation 11.3-5. The 

emission factor was also obtained from EIIP Tech. Report, Table 11.3-1. According to the EIIP 

Tech. Report, Table 11.3-5, the daily allocation for the delivery to outlets is 6 days/week.

The FORECAST function in Microsoft EXCEL was used to develop the future year gasoline 

consumption for 2011 and 2018 based on the past consumption for 2003 through 2008. The 

FORECAST tool uses linear interpolation to project future values based on historic data. By 

applying this methodology, the 2011 and 2018 growth factors were determined. The 2003 

through 2008 gasoline consumption was obtained from the United State’s Federal Highway 

Administration. The growth factors are shown in Table 4.1.1-2.

4.1.2 Aircraft Refueling 

Like vehicle refueling, aircraft refueling results in VOC. There are two processes that generate 

VOC emissions. Stage I is the displacement of vapors during the transfer of gasoline from tank 

trucks to storage tanks and vice versa. The other process is Stage II that involves the transfer of 

fuel from the tanker trucks into general aviation aircraft. The methodology employed for this 

category was developed by E.H. Pechan & Associates, Inc. utilizing the emission factors 

developed by the ERTAC workgroup. 

For Stage I and Stage II, the national-level emissions were calculated by multiplying the 

nationwide aviation gasoline (AvGas) consumption by the VOC emission factors and summing 

the emissions. 

Once the national-level emissions were calculated, they were allocated to the Petroleum 

Administration for Defense (PAD) Districts based on the amount of gasoline reported for each 

PAD. The PAD for North Carolina is PAD 1, which comprises 17 states along the Atlantic 

Coast. The emissions were then allocated to the county-level based on the number of landingoffs (LTOs) for general aviation flights per county. The amount of aviation gasoline consumed 

nationally and for PAD 1 was obtained from the US Department of Energy, Energy Information 
Area Source Emissions Inventory Documentation

Administration. The number of LTOs was obtained from the US Federal Aviation 

Administration. The 2008 LTOs were used for PAD 1 District and the counties because that is 

the only data that was available, therefore, it is assumed the LTOs remain constant between 2007 

and 2008. The VOC emission factors are shown in Table 4.1.2-1.

The following equation shows the emission estimate for the nationwide aviation gasoline 

consumption. 

US AvGas Consumption = amt of nationwide AvGas consumed * 42 gal/barrel * VOC EF 

For Stage I, the US aviation gasoline consumed is generated for each VOC emission factor and 

the total consumption is calculated by summing the emissions. The emission estimate for the 

county-level is shown in equation 4.1.2-1. 

EM = US VOC Emissions * (PAD 1 consumption/ US AvGas Consumption) * 

(County LTOs/PAD 1 LTOs) * (1 ton/2,000 lbs/year) * (1 year/365 days) 4.1.2-1

gasoline consumption. The growth factors for the Triad area are listed in Table 4.1.2-2.

4.1.3 Portable Fuel Containers 

Portable fuel containers (PFCs, or gas cans) are consumer products used to refuel a wide variety 

of gasoline-powered equipment. 

The general approach, developed by the USEPA, to calculate emissions for portable fuel 

containers is to take the inventories already prepared by the USEPA for 2002 and 2010 and apply 

linear interpolation using Microsoft EXCEL FORECAST to generate the 2007 emissions. The 

activity data for the 2002 and 2010 emission inventories were developed using the USEPA’s 

Nonroad Model, which uses a variety of variables like equipment size, equipment population, 

equipment age, RVP and air temperature to estimate activity. 

The base year emissions are calculated using equation 4.1.3-1 

EM = (m * 2007) + EM2002 * (1 year/365 days) 4.1.3-1 

where: 

 EM = total daily emissions in tons/day 

 m = (EM2010 – 2007) / (2010 – 2002) 

 EM2010 = PFC emissions per county for 2002, tons/year 

 EM2010 = PFC emissions per county for 2010, tons/year 

For future year emissions, values were also calculated using linear interpolation. The emissions 

for 2011 and 2018 emissions were determined by applying the Microsoft EXCEL FORECAST 

tool to the 2002 and 2010 portable fuel emissions supplied by the USEPA. The growth factors 

were determined by the formula FYemiss/BYemiss. The growth factors are shown in Table 4.1.3-1.

4.2 STATIONARY SOURCE SOLVENT EVAPORATION 

There are eleven subcategories that involve stationary source solvent evaporative emissions. 

They include: dry cleaning, graphic arts, solvent cleaning, automotive refinishing, architectural 

coatings, traffic markings, industrial surface coating, asphalt paving, roofing operations, 

pesticide application and consumer/commercial solvent use. The methodology used to calculate 

the emissions from these sources are described in detail in each subsection. 

4.2.1 Dry Cleaning 

The VOC emissions from dry cleaning vary with the type of process and the solvent used. For 

the most part, dry cleaning (coin-operated and conventional) are small business entities. As a 

result of their size, dry cleaning emissions are not captured as point sources. However, dry 

cleaning operations can be a significant emission source for VOC emissions, when taken 

collectively. 

The emissions from dry cleaning are estimated by multiplying the number of employees at dry 

cleaning by a national per-employee emission factor, 467 lbs of VOC/employee/year. The 

emissions estimation and emission factor used for dry cleaning were obtained from ERTAC.

The number of employees was obtained from the US Census Bureau, County Business Patterns. 

Any facilities with 100 or more employees were deemed to be point sources and not included in 

the area source emissions inventory. Table 4.2.1-1 below shows employment numbers used in 

the emissions estimation.

in Microsoft EXCEL was used to determine the future year dry cleaning employment data for 

2011 and 2018 based on the past employment data for 2003 - 2008. The FORECAST tool uses 

linear interpolation to project future values based on historic data. The dry cleaning growth

4.2.2 Graphic Arts/Printing 

Graphic arts include operations that are involved in printing of newspapers, magazines, books, 

and other printed materials, which can be divided into several subsets based upon printing 

technology. Over the last decade ink-jet and offset lithography have emerged as the dominant 

technologies. The use of oils as ink solvents and the reduction of alcohols in the fountain 

solution and in the cleanup solutions have resulted in notable reductions in emissions for offset 

lithography. Ink-jet printing results in essentially no VOC emissions. 

A number of establishments that generate emissions in this source category are in-house graphic 

arts operations at plants that are in non-printing industries. The per-capita emission factor of 

1,482 lbs VOC/employee/year provided by ERTAC was used to calculate the VOC emissions. 

The emissions are from facilities that emit less than 100 tons VOC/year. It assumes that 

facilities greater than 100 tons VOC/year will be included in the point source emissions 

inventory. The employment, obtained from the US Census Bureau, County Business Patterns, is 

based on the methodology outlined by E.H. Pechan & Associates, Inc. The base year 

employment for 2007 is in Table 4.2.2-1.

According to the Procedures document, Table 5.8-1, the activity days per week is 5 and there is 

no seasonal adjustment needed. There were no graphic arts point sources in the Triad 

maintenance area. 

The interim year and future year emissions were also calculated using the FORECAST function 

in Microsoft EXCEL to linear interpolate the graphic arts printing operations employment. The 

growth factors were determined by using historical employment data from 2003-2008. The 

growth factor in Davie County remains constant because the fluctuations in employment between 

2003 and 2008 caused the linear interpolation to be skewed. The growth factors are shown in

Solvent cleaning operations are integral to many businesses and industries, and are conducted for 

the purpose of removing grease, oils, waxes, carbon deposits, etc. from metals, plastic, or glass 

surfaces. Solvent cleaning is usually performed prior to painting, plating, inspection, repair, 

assembly, etc. The solvents used in the cleaning operations can be either in a liquid or vapor 

phase. Generally, these solvents have high vapor pressures that emit VOC emissions. 

There are two basic types of solvent cleaning techniques, cold cleaning and vapor cleaning. 

Cold cleaning machines use solvents in the liquid phase to clean and remove foreign material 

such as oils and grease from the surface of materials. Cleaning operations include 

spraying/flushing solvent or parts agitation, wipe cleaning, brushing, and immersion. 

The vapor cleaning technique can be further divided into open top degreasing and in-line 

cleaning. The open top degreasing machines are tanks designed to generate and contain solvent 

vapor. The tank is equipped with a heating system that boils the liquid solvent. As the solvent 

boils, dense solvent vapors rise and displace the air in the tank. Coolant is circulated in 

condensing coils on the top of the tank to create a controlled vapor zone within the tank. 

Condensing solvent vapors dissolve the contaminants on the surface of the workload and flush 

both the dissolved and undissolved contaminants from the workload. 

In-line cleaning machines employ automated loading on a continuous basis. These machines are 

often custom made for large-scale operations. A continuous or multiple-batch loading system

greatly reduces or even eliminates the manual parts handling associated with batch cleaning. Inline cleaning machines are enclosed to prevent solvent losses; however, entry and exit openings 

cannot be sealed. 

The VOC emissions for this category are estimated by using per employee factors obtained from 

the EIIP Tech. Report, Chapter 6, Table 6.5-2. The emission factors for these subcategories are 

listed in Table 4.2.3-1.

Federal rules are expected to reduce the VOC emission from solvent cleaning in the future years. 

The USEPA estimates (EPA420-R-00-020) that the federal rules will reduce the emissions from 

this source category by approximately 31% for open top processes and about 43% from cold 

cleaning processes. This reduction was applied to the base year emissions.

The work week is 6 days for this category. The growth factors were developed using linear 

interpolation of 2003-2008 employment data. The manufacturing employment was used for the 

electronic & other electrical: open top degreasing and miscellaneous manufacturing: cold cleaning 

subcategories. Employment for retail trade, transportation and warehousing and other services 

(except public administration) was used for the auto repair services: cold cleaning subcategory. 

Lastly, all of the employment categories were used for the miscellaneous manufacturing: open 

top degreasing subcategory. The employment categories used for the growth factors were 

determined based on the employment SIC codes used for each subcategory emissions 

calculation. The growth factors are shown in Tables 4.2.3-3-4.2.3-6.

4.2.4 Auto Body Refinishing 

Auto body refinishing operations consist of vehicle preparation, primer application, topcoat 

application and spray equipment cleaning. These operations result in significant VOC emissions. 

The solvents are typically 100% volatile and can constitute up to 6.5 lbs of VOC per gallon of 

cleaner or paint. 

The methodology outlined in E.H. Pechan & Associates based on the emission factor 

development work from ERTAC was used for estimating emissions for this category. The 

emissions calculation is based on a per employee emission factor, 89 lbs/VOC/employee. The 

number of employees for 2007 was obtained from the US Census Bureau, County Business 

Patterns, and are listed in Table 4.2.4-1.

This category includes the application of paint, primer, varnish or lacquer to architectural 

surfaces, and the use of solvents as thinners and for cleanup. 

The VOC emissions for this source category were estimated by multiplying county population in 

Table 2.2-1 by a per capita emission factor as shown in equation 4.2.5-1. The future emissions 

were determined using equation 4.2.5-2. The population growth factors in Table 2.2-2 were used 

to calculate the interim and future years’ emissions.

4.2.6 Traffic Markings 

The paint used in traffic markings operations (the painting of center lines, shoulders, etc.) emits 

VOC emissions during the drying process. 

The emission estimation used to calculate the traffic marking emissions is based upon the 

number of lane miles for each county as specified in the methodology outlined by E.H. Pechan & 

Associates, Inc. The number of lane miles was obtained from the North Carolina Department of 

Transportation (NCDOT) for 2007 as shown in the table below.

For the future years’ emissions, the growth factors were developed using linear interpolation 

with Microsoft EXCEL FORECAST function. The statewide lane miles for 2003-2008 were 

used to determine the number of lane miles for 2011 and 2018. Statewide lane miles were used 

in lieu of county lane miles because the statewide information was readily available from the US 

Federal Highway Administration.

Additionally, federal rules are expected to reduce the VOC emission from traffic markings in the 

future years. The USEPA estimates that the federal rules will reduce the emissions from this 

source category by approximately 25%. This reduction was applied to the emissions for the base 

year and the interim and future years. According to the EIIP Tech. Report, the activity is 5 days 

per week and the SAF is 1.3. 

The emissions for the base year and future years were calculated using equations 4.2.6-2 and

4.2.7 Industrial Surface Coating 

Surface coating operations involve applying a thin layer of coating (e.g. paint, lacquer, enamel, 

varnish, etc.) to the surface of an object for decorative or protective purposes. The coating 

products, which are solvent based, emit VOC emissions as the result of solvent evaporation 

during the drying or curing process. 

Ideally, the VOC emissions from industrial surface coating activities should be captured as point 

sources. From a practical standpoint, this is not always accomplished. For example, two of the 

industrial surface coating subcategories, industrial maintenance coatings and other special 

purpose coatings, utilize per capita emission factors instead of per employment emission factors. 

For industrial maintenance coatings and other special purpose coating emissions calculation, the 

population used is shown in Table 2.2-1. The employment used for the remaining subcategories 

is shown in Table 4.2.7-1.

4.2.8 Asphalt Paving 

Two types of asphalt paving are used for road paving and repair; emulsified asphalt and cutback 

asphalt. Emulsified asphalt is a type of liquefied road surfacing material made from a blend of 

water with an emulsifier. Cutback asphalt is a type of liquefied road surface that is prepared by 

blending or "cutting back" asphalt cement with various kinds of petroleum distillates. VOC 

emissions occur as the asphalt cures. 

The NCDOT specification for asphalt in 2002 was hot mix and emulsified asphalt with hot mix 

but not cutback asphalt. Surrounding states have precluded the use of cut back by statutory 
Area Source Emissions Inventory Documentation

34

provisions; which has driven asphalt manufactures to discontinue cutback production throughout 

the region. The absence of the use of cutback has resulted in substantial reductions in emissions 

from asphalt paving operations in North Carolina. 

Hot-mix is composed of high molecular weight organics with minimal vapor pressures; 

consequently, VOC emissions are negligible. The use of emulsified asphalt does result in VOC 

emissions; but the emissions are significantly less than cutback. New formulations of emulsified 

asphalt, such as cationic, continue to result in reduced emissions. The use of emulsified asphalt 

is primarily for tack coating, which is a surface preparation for the hot-mix layer. The tonnage 

of hot-mix asphalt is accounted for by the NCDOT based on districts and not on a county level 

basis. A usage factor was developed because the number of hot-mix asphalt could not be 

obtained for 2007 hot-mix asphalt amount. The amount of hot-mix asphalt for 2005 was used to 

generate the usage factor for 2007. The data from 2005 is from the 2005 Consolidated 

Emissions Reporting Rule emissions inventory. The 2005 statewide paved roads miles was 

obtained from the 2005 Highway and Road Mileage Report from NCDOT. The usage factor is 

shown in equation 4.2.8-1. 

Usage Factor = (2005 tons hot-mix asphalt) * (2,000 lbs/ton) * (0.08 gallons/sq yds)

= 617.6 gallons hot-mix asphalt/paved miles 4.2.8-1 

The 2007 county paved miles is from the 2007 Highway and Road Mileage Report from 

NCDOT. The number of paved miles per county for 2007 is listed in Table 4.2.8-1.

The VOC emissions were calculated using the emissions factor for emulsified asphalt is 9.2 lbs 

VOC/barrel and the number of gallons of emulsified asphalt per barrel 42 gallon/barrel from 

Table 17.5-2 of the EIIP Tech. Report. A SAF of 1.33 was applied to correct for the majority of 

paving operations occurring between March and November, as reported by the NCDOT. 

The growth factors were developed using linear interpolation of historic data for 2003-2008 for 

the number of paved miles per county. The growth factors are shown in Table 2.2.8-2.

4.2.9 Roofing Operations 

This category covers the installation and repair of asphalt roofs on commercial and industrial 

buildings. This category includes only hot-applied asphalt roofing, for which the only significant 

emissions source is the kettle used to heat the asphalt. The 2007 base year emissions were 

determined from E-GAS 5.0 because the number of felt, cap, and flashing squares used in North 

Carolina for 2007 was unavailable. The 2007 emissions were projected from the 2005 emissions 

submitted to the USEPA to meet the requirement of the Consolidated Emissions Requirement 

Rule. The interim and future years were also determined by using E-GAS 5.0. The growth 

factors for the Triad maintenance area are listed in Table 4.2.9-1. 

For future year emissions, the base year emissions were grown using growth factors from the EGAS 5.0 model and are listed in Table 4.2.9-2.

4.2.10 Pesticide Application 

Pesticides broadly include any substance used to kill or retard the growth of insects, rodents, 

fungi, weeds or microorganisms. Formulations of organic pesticides are commonly made by 

combining synthetic materials with various petroleum products. The petroleum products, or inert 

ingredients, act as a carrier of the active component and usually evaporate into the atmosphere. 

Agricultural Pesticides

Agricultural pesticides are applied in various manners, which directly affect the possible 

emissions associated with the application, regardless of the amount of solvent contained in the 

pesticide. There are basically three types of pesticide/herbicide application methods. One is the 

"incorporated" type, in which the product is applied and immediately incorporated into the soil. 

It is expected that little, if any, evaporation of solvent occurs in this type of application. The 

next type, "pre-emergence", is where the product is put on the ground immediately after the crop 

is planted. This provides a protective layer. Some evaporation of solvent would be expected 

with this type of application. The largest emissions would occur from "over the top" application 

of pesticides. These pesticides are sprayed directly on the foliage to kill weeds or insects. This 

application would provide an opportunity for a great deal of solvent to evaporate. 

The overall pesticide usage associated with agricultural crop production continues to slowly 

decrease in North Carolina driven by conservative pest management practices and the cost of 

pesticides as reported by the North Carolina State University (NCSU) Extension Center. The 

large majority of pesticide usage is confined to the production of tobacco and cotton crops. 

Because of the small crop size and high cash value, significant tobacco acreage is found in North 

Carolina. 

The planted crop acreage from the North Carolina Agricultural Statistic Division and crop profile 

reports prepared by the NCSU Extension Center, and other university extension services, for the

US Department of Agriculture Pest Management Center were used to estimate agricultural 

pesticide usage. Crop acreage from the North Carolina Agricultural Statistic Division was 

obtained from http://www.ncagr.com/stats/. Crop profile reports conducted by NCSU are based 

on surveys; where participation is reported to be as high as 90 percent for the more important 

cash crops. Crop profile reports for grains and soybeans do not exist for North Carolina, 

therefore, data for these crops were obtained from other state profiles and from discussions with 

representatives of the NCSU Extension Center. 

The individual crop profiles outline the current agricultural pesticide practices, i.e., the pesticide 

agents (insecticides, herbicides, fungicides), the percentage of acres treated and the pounds of 

active ingredient pesticide applied per acre. The crop profiles often report the application of the 

active ingredient (pounds of active ingredient per acre) as a range of values. For the worst case 

scenario, the highest reported value was used. The number of applications of a single pesticide 

was usually one for all pesticides. The few exceptions to one application are more than 

accounted for by the conservative practice of using the highest value of application rate. 

The pounds of active ingredients for each crop were calculated by using Equation 4.2.10-1 and 

an example calculation for soybeans follows. Table 4.2.10-1 presents the pesticides associated 

with a particular crop, the % of treated acres, and the lbs. of active pesticide ingredient per year. 

(lbs. AI/acre)CROP = ∑ (% acres treated) x (lb AI/acre)pesticide 4.2.10-1 

where AI = active ingredient. 

For soybeans, the pounds of active ingredients for the crop is:

The emission factors for each crop were calculated utilizing information from the EIIP Tech. 

Report, which relates active ingredients to VOC emissions. According to the EIIP Tech. Report, 

for every pound of active ingredient there are 2.45 lbs of VOC emitted and 90% of the emissions 

are evaporated. The emission factors for each crop were calculated using equation 4.2.10-2, with 

an example calculation for soybean following. 

EFcrop = (lb AIcrop/acre) * (2.45 lb. VOC/lbs of AI) * (0.90) 4.2.10-2 

where: 

EFcrop = emission factor in lbs VOC/active ingredient for each crop 

 AIcrop = active ingredient for each crop. 

The emission factor for soybeans is 

 lbs AI/acre for soybean = 0.844 lbs. AI/acre 

EFsoybean = (0.844 lbs active ingredient/acre) * (2.45 lbs VOC/active ingredient) * (0.90) 

 = 1.861 lbs VOC/acre. 

An exception to the above calculation was for the usage of the following pesticides: chloropicrin 

and 1,3 dichloropropene. These fumigants are widely used for treating tobacco beds for 

nematodes and constitute a major portion of the pesticide inventory. They have a moderate 

vapor pressure of 18.3 and 34 millimeters of mercury (at 77° F), respectively, and their 

formulation is approximately 96% to 98% of the active ingredient. In light of these properties, 

the VOC emissions are assumed to be equal to the application per acre, which are 79 lbs/acre for 

chloropicrin and 89.5 lbs/acre for 1,3 dichloropropene. Table 4.2.10-2 list the pounds of active 

ingredients per acre and the calculated emission factor for each crop. The number of crops 

planted for 2007 in each county was obtained from the National Agricultural Statistics Service 

website. The number of acres of each crop planted in each county is listed in Table 4.2.10-3.

An SAF of 2.4 is applied to correct for the almost exclusive use of agricultural pesticides from 

April to August. For interim year and future year emissions, the growth factors were developed 

using Microsoft EXCEL FORECAST to linear interpolate the crops acreage for 2011 and 2018 

from 2003-2008 historic data. Statewide acreage was used because the 2003-2008 acreage data 

was readily available via the NC Department of Agriculture. The acreage used in the calculation 

for 2011 and 2018 does not include oaks, barley and sorghum because the acreage for 2003-2008

4.2.11 Commercial/Consumer Solvent Use 

This category includes only non-industrial solvents that are used in commercial or consumer 

applications. The solvent containing products consist of a diverse grouping, e.g. personal care 

products, household products, automotive aftermarket products, adhesives and sealants, 

pesticides, some coatings and other commercial and consumer products that may emit VOC 

emissions. 

The VOC emissions are estimated based on per capita emissions factors. The county population 

values listed in Table 2.2-1. The population growth factors listed in Table 2.2-2 were used to 

estimate the projected future year emissions. There are seven subcategories within the 

commercial/consumer solvent use category. They are listed in Table 4.2.11-1 with their 

respective emission factor.

According to the EIIP Tech. Report, emissions from this source category occur 365 days per year 

and there is no seasonal adjustment required. Federal rules are expected to reduce the VOC 

emissions from consumer solvents in the future years. The USEPA estimates that the federal 

rules will reduce the emissions from this source category by approximately 25%. This reduction 

was applied starting with 2007 estimated emissions. The emissions for the base year and future 

year inventories were calculated using Equations 4.2.11-1 and 4.2.11-2, respectively.

4.4 OTHER MAN MADE AREA SOURCES 

Other man made area sources include forest fires, slash burning and prescribed burning, 

agricultural burning, structure fires and vehicle fires. Some of these sources, such as orchard 

heaters and certain kinds of agricultural burning, are not active during the ozone season. The 

methodology used to calculate the emissions from these sources are described in detail in each 

subsection.

4.4.1 Forest Fires 

There are two types of forest fires; wild fires, which are accidental or felonious fires and 

prescribed burns, which are intentionally set for the purpose of forest and/or grassland 

management practice. The number of acres burned in 2007 for each of these categories was 

obtained from the North Carolina Division of Forest Resources (NCDFR) and are listed in Table 

4.4.1-1. As shown in Table 4.4.1-1, there are no prescribed fires in the Triad maintenance area.

The makeup of the plant life burned in each fire can vary from woodland to brush to grassland. 

The emission factors for the southern region of the United States from AP-42, Table 13.1-2, were 

used to estimate the emissions from forest burns. The emission factors are 0.108 tons VOC per 

acre burned and 0.018 tons of NOx per acre burned. 

The NCDFR was not able to provide seasonal numbers, so the daily emissions are estimated by 

dividing by 365 days per year. For the base year 2007 and future year inventories, it is assumed 

that the number of acres burned remains relatively constant; therefore, the emissions between the 

base year and future years remain constant. The emissions were calculated using 

equation 4.4.1-1. 

EM = no. acres burned * EF * (1 year/365 days) 4.4.1-1 

where: 

EM = total daily emissions in tons/day 

EF = emission factors, VOC = 0.108 tons/acre and NOx = 0.018 tons/acre 

The VOC and NOx emission estimates, in tons/day, from forest fires for the Triad maintenance 

area are listed in Table 4.4.1-2.

4.4.2 Structure Fires 

The U.S. Fire Administration (USFA) maintains statistics on the number of fires per county. The 

number of fires per county for 2007 was derived from the USFA fire statistics. The 2007 USFA 

fire statistics were obtained from the USFA website. The structure fires category is based on 

both residential and non-residential structures. A fires per person factor was calculated for the 

residential structures based on the national number of residential fires divided by the national 

population for 2007. The fires per person factor for residential structures 0.0014 fires/person. A 

fires per person factor was also calculated for the non-residential structures based on the national 

number of non-residential fires divided by the national employment for 2007. The fires per 

employee factor for non-residential structures 0.00086 fires/employee. The 2007 county 

population was obtained from the North Carolina State Demographics and the 2007 county 

employment was obtained from the US Census Bureau, County Business Patterns. The fires per 

person factor was applied to the 2007 population for each county to determine the number of 

residential structure fires in each county. The fires per employee factor was applied to the 2007 

county employment to determine the non-residential structure fires emissions for each county. 

To determine the total emissions from structure fires, the sum of the residential and nonresidential structure fires emissions were totaled for each county. The population values are 

listed in Table 2.2-1 and the county employment is shown in Table 4.4.2-1.

burned and 1.4 lbs of NOx per ton burned. The loading factor, which is 1.15 tons of material 

burned per structural fire, was also obtained from the EIIP Tech. Report. 

According to the EIIP Tech. Report, emissions from this source category occur 365 days per year 

and there is no seasonal adjustment required. 

For future year inventories, the base year emissions were grown using the percent growth in 

population for each county. The population growth factors were used because they are more 

conservative than the employment growth factors. The population growth factors are in 

Table 2.2-2. The structure fires emissions for the 2007 base year were calculated using 

equation 4.4.2-1. The projected future year inventories were calculated using equation 4.4.2-2.

4.4.3 Vehicle Fires 

Vehicle fire emissions within the maintenance area are estimated by considering the estimated 

number vehicles burned in the Triad area counties, the amount of material burned (the fuel 

loading) in a vehicle fire, and the emission factors for the open burning of automobile 

components. The assumptions for amount of material burned and the emission factors were 

based on the USEPA’s AP-42, Section 2.5 - Open Burning. 

The estimated number of vehicle fires was determined by apportioning a national fire statistic to 

a county level. The USFA maintains national-level fire statistics. The number of vehicle fires 

nationwide in 2007 was 258,000. The number of national vehicle fires was apportioned to a 

state-level using ratio of North Carolina vehicle miles traveled (VMT) to U.S. VMT 

(249,698,650 miles/3,029,822 x 106

 miles). The number of statewide vehicle fires was then 

apportioned to a county level based on VMT in each county. The nationwide VMT statistics 

were obtained from the U.S. Department of Transportation, Federal Highway Administration 

website. The statewide and county VMT is Highway Performance Monitoring System data that 

was received from the NCDOT. 

The above methodology was employed to calculate the vehicle fire emissions per county. For 

2007, the VMT for the Triad maintenance area counties is listed in Table 4.4.6-1.

The amount of vehicle material burned (the fuel loading) in a vehicle fire was estimated by 

assuming that an average vehicle has 500 lbs. of components (0.25 tons) that can burn in a fire, 

based on a 3,700 lbs. average vehicle weight (CARB, 1995). 

The emission factors were obtained from AP-42, Table 2.5-1. The emission factors are 32 lbs. of 

VOC per ton burned and 4 lbs. of NOx per ton burned.

The projected future year emissions were developed by linear interpolation of the number of 

vehicle miles traveled for each county. The vehicle miles traveled was obtained from the NC 

DOT Highway Performance Management System. As with previous categories, the historic data 

used if for the linear interpolation is for 2003-2008. These growth factors are listed in 

Table 4.4.6-2 below.

4.4.4 Charbroiling 

Commercial charbroiling produces VOC emissions. According to the methodology in the EIIP 

Tech. Report, county Health Departments should be able to provide the number of restaurants in 

a county as well as the percentage of those restaurants that charbroil meat. The NCDAQ was 

able to obtain the number of restaurants in each county for 2007 from the North Carolina 

Division of Environmental Services, Inspection, Statistics and Fee Branch. To determine the 

percentage of charbroiling restaurants, the county Health Departments of several counties were 

surveyed. Three of the seven counties responded. The average percentage of the three 

responding counties was used as a surrogate for the number of charbroiling restaurants for all 

counties statewide. The three counties that supplied data were Durham County – 8%, Guilford 

County – 13% and Wake County 19%. The average between the three equates to 13%. Table 

4.4.4-1 is the number of restaurants in 2007 in each county.

meat. Emissions from this source category occur 365 days per year that results in no seasonal 

adjustment requirement. For projected future year emissions, growth factors were calculated

4.4.5 Open Burning – Municipal Solid Waste and Yard Trimmings 

It was assumed that all municipal solid waste (MSW) and yard trimmings were burned in the 

open for solid waste generated outside the municipal corporate limits. According to the EIIP 

Tech. Report, Table 16.5-1, it is estimated that 3.77 lbs. of MSW is generated per person per day 

and 0.64 lbs. of yard trimmings are generated per person per day. Since it is illegal to burn 

within the corporate limits, the rural population for 2007 for each county was determined. The 

rural population was calculated by applying the 2000 census rural population percentage to the 

total 2007 county population. The 2007 total population for each county was obtained from the 

North Carolina Office of State Budget and Management, State Data Center. Table 4.4.5-1 shows 

the rural population percentage and the total rural population for each county.

Guilford 1.6 7,347 

The emission factors for open burning of MSW were obtained from EIIP Tech. Report, 

Table 16.4-1. The emission factor for VOC is 6.676 lbs. per ton MSW burned and 6 lbs. NOx per 

ton MSW burned. The emission factor for VOC is the total VOC – Acetone = 8.556 - 1.88 = 

6.676 pounds VOC/ton burned/year. 

The emission factors for open burning of yard trimmings, from the EIIP Tech. Report, 

Section 4.1.3, Table 16.4-7, are 28 lbs. VOC per ton yard trimmings burned per year and 6 lbs. 

NOx per ton yard trimmings burned per year. Emissions from these source categories occur 365 

days per year, therefore, no seasonal adjustment is required. The projected future year growth 

factors are in Table 2.2-2. 

The base year emissions were calculated using equation 4.4.4-1 and the projected future year 

emissions were calculated using equation 4.4.4-2.

PJEM = projected future emissions in tons/day 

 GFa = growth factor (a) for projected future years 

Since the NCDAQ has an open burning regulation that prohibits the burning of man-made 

materials, the emissions estimated for MSW were reduced to account for this rule. The control 

efficiency is 100% since no burning yields no emissions. The rule penetration is also 100% 

since the regulation prohibits the burning of man-made materials statewide. Finally the rule 

effectiveness was set to a conservative 50% for the base year since the NCDAQ knows that 

burning of man-made materials does occur. The NCDAQ has started an aggressive campaign to 

make the public aware that it is illegal to burn man-made materials. The NCDAQ has sponsored 

radio ads as well as billboard signs in an effort to educate the public. Additionally, the NCDAQ 

has developed an educational video discussing open burning and the State’s regulation. This 

video has been distributed to the fire departments across the State. Finally, at the 2009 North 

Carolina State Fair, the NCDAQ had a booth that allowed staff to talk with the general public 

about the open burning regulations and provide hand outs that discussed what was legal to burn. 

The NCDAQ expects that as the public becomes more aware of the open burning regulations, the 

rule effective will increase to 67% by 2018. A gradual increase in the rule effectiveness for the 

interim years was applied. The table below displays the rule effective numbers used in 

calculating the emissions.

The “demand for energy” for these fuel types is known as fuel usage. The 2007 fuel usage data 

for North Carolina was obtained from the U.S. Department of Energy, Energy Information 

Administration (EIA) website for fuel consumption. 

The following tables show the 2007 fuel usage for the residential, commercial and industrial 

source sectors in North Carolina.

The emission factors used to estimate the emissions, except residential wood, were obtained 

from E.H. Pechan & Associates, Inc. based on the ongoing emission factor development work 

conducted by the Eastern Regional Technical Advisory Group (ERTAC) in conjunction with the 

USEPA. The residential wood emission factors were obtained from a tool developed by the 

USEPA to calculate the emissions generated from residential wood combustion.

Residential Combustion Sources

The residential category for the fuel oil, coal, NG and LPG sources fuel usage for the Triad 

nonattainment area was calculated by apportioning the State total fuel usage to a county level. 

Fuel usage was apportioned by applying the ratio of the number of households heated with the 

appropriate fuel type in a county to the total households in the State heated with the appropriate 

fuel type, see equation 4.4.6-1 below. 

no. gal. fuel per cnty = (no. gal. fuel for state) * (no. housing units heated by fuel per cnty)

 (no. housing units heated by fuel in state) 4.4.6-1 

The number of households heated with fuel oil, coal, NG and LPG was obtained from the U.S. 

Census Bureau based on the latest census data which is 2000. The number of households heated 

per fuel type is shown in Table 4.4.6-4.

For the residential wood combustion emissions, the USEPA developed a tool to generate the 

emissions for this subcategory. The emissions for this subcategory are for housing units with 

fireplaces as their main source of heating. The activity data used in the calculation was also 

obtained from the tool the USEPA developed to calculate residential wood combustion 

emissions. The emissions calculation is shown in equation 4.4.6-2 below. 

EM = activity data * EF * (1 year/365 days) 4.4.6-2 

 2,000 lbs/ton 

where: 

EM = total daily emissions in tons/day 

EF = emission factors for VOC = 18.9 lbs/ton burned/year and 

 NOx = 2.6 lbs/ton burned/year

Commercial and Industrial Combustion Sources

Commercial and industrial fuel usage was apportioned according to the number of employees in 

the commercial/industrial business establishments in the State and the Triad nonattainment 

counties. The commercial employment data was obtained from the County Business Patterns for 

NAICS codes 42(wholesale trade) through 81(other services - except public administration). For 

industrial combustion, the employment data was also obtained from the County Business 

Patterns for NAICS codes 31-33(manufacturing). Fuel usage was apportioned to the county 

level by applying the ratio of county employment to the total State employment, see 

equation 4.4.6-3.

The total number of employees for these establishments was used to allocate emissions to the 

county level. The 2007 commercial and industrial employment for each county are shown in

For the residential source sectors, the growth factors are based on the population for each county. 

The population growth factors are in Table 2.2-2. 

The manufacturing (NAICS 31), wholesale trade (NAICS 42) and retail trade (NAICS 44) 

establishments were used to represent the employment data for the commercial and industrial 

source sectors. The FORECAST function in Microsoft EXCEL was used to determine the future 

year employment data for 2011 and 2018 based on the past employment data for 2003 - 2008. 

The FORECAST tool uses linear interpolation to project future values based on historic data.

The growth factors were developed based on the ratio of the base year (2007) employment to the 

future years (2011 and 2018) employment, see equation 4.4.6-4 below. 

Commercial/Industrial Growth Factors = FYemp 4.4.6-4

where: 

BYemp = 2007 employment per county 

 FYemp = future year employment per county 

Based on the manufacturing employment data in Table 4.4.6-5 above, the commercial and 

industrial growth factors for each county are shown in Table 4.4.6-7 below.

where: 

 EMcoal = daily total coal emissions in tons/day 

 EMNG = daily total Ng emissions in tons/day 

 EMLPG = daily total LPG emissions in tons/day 

 EMfuel oil = daily total fuel oil emissions in tons/day 

 EMwood = daily total wood emissions in tons/day 

 EFcoal = emission factor for coal combustion per pollutant 

 EFNG = emission factor for NG combustion per pollutant 

 EFLPG = emission factor for LPG combustion per pollutant 

 EFoil = emission factor for fuel oil combustion per pollutant 

 EFwood = emission factor for wood combustion per pollutant 

The emissions for the projected future years for all of the small stationary combustion sources 

were calculated using equation 4.4.6-10 

PJEM = EM * GFa 4.4.6-10 

where: 

 PJEM = projected future year emissions in tons/day 

 GFa = growth factor (a) for projected future years. 

The NOx and VOC emissions estimates for each fuel combustion source, in tons/day, for the 

residential source sector are listed in Tables 4.4.6-8 through 4.4.6-12. Based on U.S. Census 

Bureau data, Davie County does not use coal as a means of residential heating, therefore, there 

are no emissions estimates for coal combustion in Davie County.

The NOx and VOC emissions estimates for each fuel combustion source, in tons/day, for the 

commercial and industrial source sectors are listed in Tables 4.4.6-13 through 4.4.6-19. There 

are no wood combustion emissions estimates for the commercial and industrial source sectors 

because the only emission factors for wood combustion is residential furnaces which are 

captured in the residential source sector. Additionally, there are no coal combustion emissions 

for the industrial source sector because the emissions generated from coal are accounted for in 

the point sources inventory.

Point sources are those stationary sources that require an air permit to operate. In general, these 

sources have a potential to emit more than 5 tons per year of CO, NOx, PM, SO2 and/or VOC 

from a single facility. Point sources that meet this criterion are accounted for in the point source 

emissions inventory. They are subtracted from the area source emissions inventory to prevent 

double counting of emissions. The 2007 point source emissions data was subtracted from the 

overall area source emissions calculation. 

Tables 4.4.6-20 – 4.4.6-23 illustrates the point source emissions that were subtracted from the 

commercial fuel oil and commercial NG sources as well as the industrial fuel oil and industrial 

NG sources. The remaining commercial and industrial combustion sources do not have point 

source emissions for the Triad nonattainment counties.

4.4.7 Agricultural Burning 

This source subcategory covers burning practices used to clear and/or prepare land for planting. 

These operations include stubble burning, burning or agricultural crop residues, and the burning 

of stand field crops as part of harvesting (e.g., sugar cane). According to the North Carolina 

Department of Agriculture, when soybeans are double cropped with wheat, the wheat stubble is 

usually burned back after harvest about one fourth of the time. According to Dr. J. Dunphy, a 

soybean specialist at North Carolina State University, the acres of soybean double cropped with 

wheat in North Carolina is approximately equal to the acres of wheat planted. Therefore, 1⁄4 of 

the acreage of wheat planted in 2002 was used to calculate the emissions from agricultural 

burning practices in North Carolina. 

The fuel loading factor and the yield of pollutant for burning wheat stubble was obtained from 

AP-42, Table 2.4.2. The fuel loading factor is 1.9 tons of fuel consumed per acre burned. The 

yield of pollutant was dependent upon whether the field was head-fire burned or back-fire 

burned. The percentage of each burning type used was not available, therefore, the assumption 

was made that each type was used 50% of the time. The yield of pollutant used, 11 lbs. of VOC 

per ton of fuel consumed, is an average of the two types of burning. To calculate the emission 

factor for VOC emissions, the fuel loading factor is multiplied by the yield of pollutant.

 EFVOC = (1.9 tons/acre) (11 lbs VOC/ton burned) 

 = 20.9 lbs VOC/acre burned 

The annual emissions were calculated using the number of acres burned and the per acre 

emission factor. According to the North Carolina Department of Agriculture, field burning 

occurs only during June and July, therefore, the daily emissions for agricultural burning were 

calculated by dividing the annual emissions by 61 days. No seasonal adjustment is needed since 

all of the burning occurs during the ozone season. 

The number of acres of wheat planted was obtained from the North Carolina Agriculture Statistic 

Division and is tabulated in Table 4.4.7-1 below.

The projected future year emissions were grown using growth factors that were linear 

interpolated using Microsoft EXCEL FORECAST. The historic data for the total number of 

wheat acres planted for 2003-2008 were used for the linear interpolation. Statewide wheat 

acreage was used because it was available for 2003-2008. The growth factors are shown in 

Table 4.4.7-2.

4.4.8 On-Site Incineration 

On-site incineration occurs at industrial and commercial facilities. Typically, these facilities are 

captured in the point source inventory. Emissions from this source category have been included 

to account for any smaller facilities that are not included in the point source emissions inventory. 

Emissions are calculated and projected based on county population (Table 2.2-1 and 

Table 2.2-2). The emission factors are 8.556 lbs VOC/ton waste and 2.5 lbs NOx/ton waste. 

Waste fuel loading factor is 0.023 tons refuse per person per year. Industrial and commercial 

facilities have the same emission factors. The emissions for 2007 were calculated using equation 

4.4.8-1 and the emissions for the base year and the projected future years were calculated using 

equation 4.4.8-2.

4.5 BIOGENIC EMISSIONS 

Biogenic emissions are primarily VOC emissions from vegetation and are kept constant through 

all years when modeling ozone. Since the redesignation plan is a comparison of future year to 

base year emissions and the biogenic emissions are kept constant, the biogenic emissions do not 

play a part in the redesignation demonstration. Upon discussions with the USEPA Region 4, it 

was agreed that the biogenic emissions did not need to be estimated for the redesignation 

demonstration and maintenance plan.

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

1.0 INTRODUCTION AND SCOPE 

As a requirement of the 1997 8-hour ozone standard implementation rule, areas that were 

maintenance for the 1-hour ozone standard and designated as attainment for the 1997 8-hour 

ozone standard have to submit a 110(a)(1) maintenance plan within 3 years of being designated 

as attainment. The Greensboro/Winston-Salem/High Point (referred to as the Triad area) 1-hour 

ozone maintenance area falls into this category and is required to have a 110(a)(1) maintenance 

plan. The 1-hour ozone maintenance area includes Davidson, Forsyth and Guilford Counties and 

a small portion of Davie County. For the purpose of this maintenance plan, emissions will be 

estimated for all of Davie County. 

The scope of this appendix covers only the procedures associated with on-road mobile sources. 

On-road mobile sources produce nitrogen oxides (NOx), volatile organic compounds (VOCs), 

along with a host of other pollutants. An emissions inventory comparison is necessary to 

determine maintenance. The years used for the comparison must include a base year (2007), at 

least one interim year (2011), and a future year (2018). The emissions comparison will be done 

for a typical ozone season day. 

2.0 OVERALL METHODOLOGY 

2.1 EMISSION ESTIMATION APPROACH 

Mobile source emissions are estimated by the methodologies suggested in the United States 

Environmental Protection Agency (USEPA) documents Emissions Inventory Guidance for 

Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards 

(NAAQS) and Regional Haze Regulations, Policy Guidance on the Use of MOVES2010 for 

State Implementation Plan Development, Transportation Conformity, and Other Purposes (EPA420-B-09-046, December 2009), and Technical Guidance on the Use of MOVES2010 for 

Emission Inventory Preparation in State Implementation Plans and Transportation Conformity 

(EPA-420-B-10-023, April 2010). 

In December 2009, the USEPA released a new model for mobile sources. MOVES (MOtor 

Vehicle Emissions Simulator) is a computer program designed by the USEPA to estimate air 

pollution emissions from mobile sources. MOVES2010a (hereafter referred to as MOVES) 

replaces the USEPA’s previous emissions model for on-road mobile sources, MOBILE6.2. 

MOVES can be used to estimate exhaust and evaporative emissions as well as brake and tire 

wear emissions from all types of on-road vehicles. 
On-road Mobile Sources Documentation 2 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

Compared to MOBILE6.2, MOVES incorporates substantially newer emissions test data and 

accounts for changes in vehicle technology and regulations as well as improved understanding of 

in-use emission levels and the factors that influence them. Also, MOVES has a completely new 

database-centered software framework. 

The estimation of emissions from mobile sources involves multiplying an activity level by an 

emission factor. Previously this was done using MOBILE6.2 to calculate an emissions factor 

and multiplying it by the vehicle miles travelled (VMT). One important new feature of MOVES 

is the option to calculate emissions either as inventory estimates (total emissions in units of 

mass) or, emission rates (emissions per unit of distance for running emissions or per vehicle for 

starts, extended idle and resting evaporative emissions) in a look-up table format. 

Use of the inventory option simplifies the post-processing of MOVES output, but it requires 

VMT and vehicle population data as an input to MOVES. When using the emission rates option, 

VMT and vehicle population are applied during post-processing external to MOVES. Either 

approach can be used to develop emissions estimates for state implementation plans (SIPs) and 

regional conformity analyses. If inventory option is selected, MOVES provides emissions 

estimates as mass, using VMT and vehicle population entered by the user. If emission rate option 

is selected, MOVES provides emission rates as mass per unit of activity. The emission rates 

option produces a look-up table of emission rates that must be post-processed to produce an 

inventory. The NCDAQ is electing to run the model in the inventory mode due to faster model 

run times and fewer post-processing requirements. 

3.0 QUALITY ASSURANCE MEASURES 

The quality assurance (QA) for the highway mobile source category can be broken into two 

components: 1) input files and 2) MOVES outputs/summaries. Each of these components is 

detailed in the paragraphs below. 

After the speed and VMT information is acquired from the North Carolina Department of 

Transportation (NCDOT), the speed information is checked for reasonableness against previous 

sets of speeds for the areas. Once the speeds are deemed reasonable, the NCDAQ enters the 

speed information into MOVES input files. In addition to the speed information, the user enters 

data to characterize local meteorology, fleet and activity information. All input files are checked 

against a “key” with the original source of the information. This QA step is always performed 

by a person other than the one who generated the files. If any discrepancies are found, they are 

noted back to the person who generated the input files for correction. Additionally, a report is 

kept that identifies the person who produced the input file, the person that QA’d the file, and 
On-road Mobile Sources Documentation 3 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

where the data originated. Once the input files have passed through the QA procedure, MOVES 

is run to generate emissions. 

4.0 DISCUSSION OF ON-ROAD MOBILE SOURCES 

On-road mobile sources produce NOx, and VOC, along with a host of other pollutants. 

Emissions of these two pollutants are estimated in the on-road mobile source inventory for the 

maintenance plan. The objective of the following section is to describe the source category, the 

input files, and the emissions estimation procedures. This section also includes tables 

summarizing the estimated emissions for the projection years by county. 

4.1 Introduction and Scope 

On-road highway mobile sources are considered as those vehicles that travel on the roadways. 

On-road mobile sources are a major contributor to NOx emissions in North Carolina and a less 

significant contributor to VOC. Emissions from motor vehicles occur throughout the day while 

the vehicle is in motion, at idle, parked, and during refueling. All of these emissions processes 

need to be estimated in order to properly reflect the total emissions from this source category. 

A very important component of the highway mobile emission estimation process is interagency 

consultation. The primary transportation partners involved in the Triad interagency consultation 

process included: NCDOT, USEPA, Federal Highway Administration (FHWA), Greensboro 

municipal planning organization (MPO), High Point MPO, Piedmont Triad regional planning 

organization (RPO), Winston-Salem Forsyth MPO, the Northwest Piedmont RPO, and the 

Piedmont Authority for Regional Transportation (PART). Specifically, PART runs the travel 

demand model (TDM) for the urban areas and provides speeds and VMT; the NCDOT was 

consulted for speeds and VMT for the rural counties where the Triad urban TDM did not extend. 

The NCDAQ had recently consulted with the transportation partners and developed MOVES 

input data for all counties in North Carolina for the year 2007 in conjunction with modeling 

being undertaken for the Southeastern Modeling, Analysis, and Planning (SEMAP) Project. 

Since this was the base year of analysis for the Triad 110(a)(1) Maintenance Plan, this data was 

suitable for use for the base year 2007. 

For the year 2011, MOVES inputs were available from the recent update to the fine particulate 

matter redesignation demonstration and maintenance plan. The transportation partners agreed 

that the activity data we used for Davidson and Guilford Counties in the fine particulate matter 

plan update was the latest and should be used as inputs to the MOVES model. For Forsyth 

County, the transportation partners reviewed the most recent data the NCDAQ possessed from 
On-road Mobile Sources Documentation 4 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

the latest conformity determination and also agreed that the files were the most up to date and 

accurate representation for the emissions comparison. For the year 2018, no year-specific data 

had been collected for recent modeling or conformity exercises for Davidson, Guilford, or 

Forsyth Counties. However, it was possible to interpolate to the year 2018 from the latest data 

provided and the transportation partners agreed on that approach. 

Since only a small portion of Davie County is covered by the TDM, the NCDAQ determined that 

the speeds and VMT provided by PART were not adequate for the analyzing the county as a 

whole. Therefore, for Davie County the off-peak Wake County speeds, along with Highway 

Performance Maintenance System (HPMS) VMT were used for all three years.

4.2 MOVES Input Assumptions 

Due to the size and the complexity of the MOVES input and output files, the MOVES input files 

and output files will be provided electronically. 

4.2.1 Speed Assumptions 

Vehicle power, speed, and acceleration have a significant effect on vehicle emissions. MOVES 

models those emission effects by assigning activity to specific drive cycles or operating mode 

distributions. The distribution of vehicle hours traveled (VHT) by average speed was used to 

determine an appropriate operating mode distribution. The Average Speed Distribution importer 

in MOVES calls for a speed distribution in VHT in 16 speed bins, by each road type, source 

type, and hour of the day included in the analysis. The methodology used to develop the 

average speed distribution inputs is documented below. 

The speeds for the urban areas covered by the MPOs were generated from the region’s TDM. 

The speeds for the urban, modeled areas of Forsyth, Guilford, and Davidson counties were 

provided by PART. Speeds for rural, non-modeled areas in Davidson Counties were generated 

by NCDOT. Since only a small area of Davie County is covered by a TDM, off-peak Wake 

County speeds were used for Davie County. The NCDAQ believes that the off-peak speed 

assumptions are a better representation of average speeds in North Carolina then the default 

speed assumptions in the MOVES model or the modeled speed for the small portion of Davie 

County covered by the TDM. Tables 4.2.1-1 through 4.2.1-5 provide a summary of the speeds in 

miles per hour (mph).

MOVES uses four different roadway type categories that are affected by the average speed 

distribution input: rural restricted access, rural unrestricted access, urban restricted access, and 

urban unrestricted access (these road types are discussed in more detail in Section 4.2.6). In 

MOVES, local roadways are included with arterials and collectors in the urban and rural 

unrestricted access roads category. In MOVES, the USEPA recommends that the average speed 

distribution for local roadway activity be included as part of a weighted distribution of average 

speed across all unrestricted roads along with the distribution of average speeds for arterials and 

connectors. 

When only a single average speed is available for a specific road type and that average speed is 

not identical to the average speed in a particular speed bin, MOVES guidance stipulates that 

users should apply the following formula for creating the appropriate speed distribution among 

two adjacent speed bins. 

The general formula is: 

VHT Fraction A in Speed Bin with closest average speed lower than observed average speed + 

VHT Fraction B in Speed Bin with closest average speed higher that observed average speed = 1 
On-road Mobile Sources Documentation 8 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

VHT Fraction A(low bin) = 1 – [(observed average speed – average speed of lower speed bin) / 

(average speed of higher speed bin – average speed of lower speed bin)] 

VHT Fraction B(high bin) = 1- [(average speed of higher speed bin – observed average speed) / 

(average speed of higher speed bin – average speed of lower speed bin)] 

Or more simply: VHT Fraction B = 1 – VHT fraction A 

The following is an example of applying the above equations. If the single average speed for a 

roadway is 58 miles per hour, the average speed distribution will be split between the 55 and 60 

mph speed bins. The appropriate VHT fractions are found with the following equations: 

VHT fraction A(low bin) = 1 – [(58 mph Avg. Speed – 55 mph (Bin Speed)) / (60 mph (Bin Speed) 

– 55 mph (Bin Speed)] = 0.4 

VHT fraction B(high bin) = 1 – [(60 mph (Bin Speed) – 58 mph Avg. Speed) / (60 mph (Bin Speed) 

– 55 mph (Bin Speed)] = 0.6 

VHT Fraction A(low bin) + VHT Fraction B(high bin) = 1 

 0.4 + 0.6 = 1 

As stated above, MOVES uses only four different roadway types: rural restricted access, rural 

unrestricted access, urban restricted access and urban unrestricted access. This means that the 

speeds for multiple roadway types need to be combined into the appropriate speed bins. To 

create the speed bin fractions for combined roadways the VMT for each road way is used to 

weight the speed bin fraction. For example, below are speeds and VMT for urban restricted 

access road types: 

Road type Speed 

(miles/hour) 

VMT 

(hourly miles) 

Urban Interstate 63 250,000 

Urban Freeway 56 100,000 

The first step is to determine the speed bin fractions for each road type separately. For the urban 

interstate road type, the speed 63 is split between the MOVES speed bins of 60 and 65 as 

described above, which results in the VHT fractions of 0.4 and 0.6 for speed bins 60 and 65, 
On-road Mobile Sources Documentation 9 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

respectively. Similarly, the speed for the urban freeway road type (56 miles/hour) is split 

between the MOVES speed bins of 55 and 60 and results in the VHT fractions of 0.8 and 0.2, 

respectively. 

The next step requires road type VMT to weigh the VHT Fractions so that the final MOVES 

speed bin fractions can be developed. The VHT Fraction, specific to the road type and speed 

bin, are multiplied by the corresponding hourly VMT. These hourly totals are divided by the 

total VMT for that hour for the road type category (in this example, urban restricted access 

includes urban interstate and urban freeway). The following equation is used to calculate the 

combined speed bin fractions: 

Where: 

RT = the HPMS road type 

In this example, the HPMS road types are urban interstate (UI) and urban freeway (UF) and the 

speed bins are 55, 60 and 65. The table below summarizes the speed bin fractions for this 

example. 

HPMS Road Type Speed Bin 55 Speed Bin 60 Speed Bin 65 

Urban Interstate 0.0 0.4 0.6 

Urban Freeway 0.8 0.2 0.0 

Using the equation below, the final MOVES speed bin fractions are calculated for the urban 

restricted access road type. 

VHT(Speed Bin X) = 

[(VHT Fraction(UI) * hourly VMT(UI)) + (VHT Fraction(UF) * hourly VMT(UF))]

(hourly VMT(UI) + hourly VMT(UF)) 

VHT(Speed Bin 55) = 

 [(0.0 * 250,000) + (0.8 * 100,000)]

(250,000 + 100,000) 

VHT(Speed Bin 55) = 0.2286 

 

VHT(Speed Bin 60) = 

 [(0.4 * 250,000) + (0.2 * 100,000)]

(250,000 + 100,000) 
On-road Mobile Sources Documentation 10 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

VHT(Speed Bin 60) = 0.3428 

VHT(Speed Bin 65) = 

 [(0.6 * 250,000) + (0.0 * 100,000)]

(250,000 + 100,000) 

VHT(Speed Bin 65) = 0.4286 

The sum of the VHT fractions for all speed bins within a road type category must add up to 1.0. 

The hourly VHT fractions by speed bin and road type are then processed through a MOVES 

supplied converter to develop the speed distribution file by hour and road type. 

4.2.2 Vehicle Age Distribution 

The age distribution of vehicle fleets can vary significantly from area to area. Fleets with a higher 

percentage of older vehicles will have higher emissions for two reasons. Older vehicles have 

typically been driven more miles and have experienced more deterioration in emission control 

systems. Additionally, a higher percentage of older vehicles also implies that there are more vehicles 

in the fleet that do not meet newer, more stringent emissions standards. Surveys of registration data 

indicate considerable local variability in vehicle age distributions. 

For SIP and conformity purposes, the USEPA recommends and encourages states to develop local 

age distributions. The MOVES model categorizes the vehicle fleet into different vehicle classes and 

more model years than MOBILE6.2. A typical vehicle fleet includes a mix of vehicles of different 

ages. MOVES covers a 31 year range of vehicle ages, with vehicles 30 years and older grouped 

together. MOVES allows the user to specify the fraction of vehicles in each of 30 vehicle ages for 

each of the 13 source types in the model. 

Local age distributions can be estimated from local vehicle registration data. The vehicle age 

distribution comes from annual registration data for North Carolina from the NCDOT. For this 

analysis, the age distribution was generated based on 2007 data for the year 2007 and the 2008 

data for 2011 and 2018. The NCDOT provided the data based on the number of vehicle types 

per year from 1974 through 2007(8). Vehicles greater than 25 years old were combined and 

included as the 25th model year. The vehicle count information is provided for nine vehicle 

types; light duty gas vehicles (LDGV), light duty diesel vehicles (LDDV), light duty gas trucks 1 

(LDGT1), light duty gas trucks 2 (LDGT2), light duty diesel trucks 1 (LDDT1), light duty diesel 

trucks 2 (LDDT2), heavy duty gas vehicles (HDGV), heavy duty diesel vehicles (HDDV) and 

motorcycles (MC). LDDT1 and LDDT2 are combined and labeled as light duty diesel trucks 

(LDDT). Since MOVES categorizes the vehicle fleet into different vehicle classes and more model 

years, EPA has created data converters that take registration distribution input files created for 

MOBILE6.2 and converts them to the appropriate age distribution input tables for MOVES.

4.2.3 Vehicle Mix Assumptions 

Vehicle mix or VMT mix is used by MOVES to convert annual VMT to VMT by HPMS class, 

VMT fractions by hour, and VMT by road type distribution. The vehicle mix is developed by the 

same method used in MOBILE6.2, as outlined below. The resulting file is then used in a 

MOVES supplied converter to develop the VMT by HPMS class, VMT fractions by hour, and 

VMT by road type distribution. 

The vehicle mix refers to the percentage of different vehicle types on each of the 12 FHWA road 

types. These road types are listed above in the speed assumptions section. It is critical for 

estimating on-road mobile emissions in an area to use data that accurately reflects the vehicles 

types traveling on each of these different road types. 

In August 2004, the USEPA released the guidance document EPA420-R-04-013, Technical 

Guidance on the Use of MOBILE6.2 for Emission Inventory Preparation, which outlines how to 

convert the Highway Performance Monitoring System (HPMS) traffic count data to MOBILE6.2 

vehicle mix data. Outlined below is the methodology used to convert the 13 HPMS vehicle 

types count data reported to FHWA and generate a state specific vehicle mix. 

The North Carolina HPMS data used to generate the statewide vehicle mix was based on 2007 

for the 2007 base year and the 2008 data counts for the 2011 interim year and the 2018 future 

year. The use of the 2008 data for the year 2011 and 2018 is described below. Table 4.2.3-1 

shows the percent of vehicles per vehicle type for each of the 12 road classes. 

Table 4.2.3-1 2008 North Carolina HPMS Data 

4.2.4 Disaggregating State Specific Information 

Section 4.1.5 of Technical Guidance on the Use of MOBILE6.2 for Emission Inventory 

Preparation, illustrates how to map the HPMS statewide vehicle data to general MOBILE6.2 

vehicle categories. This mapping is outlined below:

The HPMS data in Table 4.2.3-1 was grouped into these five general categories for each road 

type. In order to expand the five general categories to the 16 vehicle types used in MOBILE6.2, 

the national average VMT fractions by each vehicle class were used. The 2008 fractions were 

used since the state specific data is from 2008. The national average data was obtained from 

Table 4.1.2 in Technical Guidance on the Use of MOBILE6.2 for Emission Inventory 

Preparation. An example for rural interstates is illustrated below: 

From Table 4.2.3-1 above: 

 Passenger Cars = 60.13% 5 axel Trailer = 17.65% 

 Pickup Trucks = 13.72% 6 axel Trailer = 0.66% 

 Bus = 1.04% 5 axel Multi Trailer = 0.51% 

 2 axel Trucks = 2.86% 6 axel Multi Trailer = 0.23% 

 3 axel Trucks = 0.75% 7 axel Multi Trailer = 0.15% 

 4 axel Trucks = 0.05% Motorcycles = 0.38% 

 4 axel Trailer = 1.86% 
On-road Mobile Sources Documentation 13

Therefore, the five general categories are: 

Motorcycles = 0.38% 

Light Duty Vehicles = 60.13% 

Light Duty Trucks = 13.72% 

Heavy Duty Buses = 1.04% 

Heavy Duty Vehicles = 24.73%

trucks are:

Using the methodology described in Section 4.1.5 in Technical Guidance on the Use of 

MOBILE6.2 for Emission Inventory Preparation the new 2008 North Carolina statewide mix 

was developed. The basic formula for developing the mix is shown below, 

 Vehicle Type = (2008 M6.2 fraction for vehicle) X (2008 State total for group) .

2011 and 2018 Statewide Vehicle Mix

Once the 2008 new vehicle mix was generated, the other years were created using the 

methodology described in Section 4.1.4 in Technical Guidance on the Use of MOBILE6.2 for 

Emission Inventory Preparation. This method grouped light duty vehicles, light duty trucks and 

motorcycles together and heavy duty buses, heavy duty trucks and heavy duty vehicles together. 

The combined percentages for these groupings are listed below. 

 Light Duty Vehicles = 74.23% 

 Heavy Duty Vehicles = 25.77%

This method was used to generate the future year, 2018, vehicle mix as well. The North Carolina 

transportation partners consider the statewide vehicle mix to be the best representation of the 

vehicle population in the Triad nonattainment area. The vehicle mixes for all years can be found 

in Section 5.1 of this appendix. 

As stated earlier in this section, vehicle mix or VMT mix is used in MOVES converters to 

develop VMT by HPMS class, VMT fractions by hour, and VMT by road type distribution, 

which are inputs to the model. 

4.2.5 Vehicles/Equipment: On-Road Vehicle Equipment 

The Vehicles/Equipment menu item and panel is used to specify the vehicle types that are 

included in the MOVES run. MOVES allows the user to select from among 13 “source use 
On-road Mobile Sources Documentation 17 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

types” (the terminology that MOVES uses to describe vehicle types), and four different fuel 

types (gasoline, diesel, compressed natural gas (CNG), and electricity). 

For SIP and regional conformity analyses, users must select the appropriate fuel and vehicle type 

combinations in the On Road Vehicle Equipment panel to reflect the full range of vehicles that 

will operate in the county. In general, users should simply select all valid diesel, gasoline, and 

CNG (only transit buses) vehicle and fuel combinations, unless data is available showing that 

some vehicles or fuels are not used in the area of analysis. 

4.2.6 Road Type 

The Road Type Panel is used to define the types of roads that are included in the run. MOVES 

defines five different Road Types: 

• Off-Network (roadtype 1) – all locations where the predominant activity is vehicle starts, 

parking and idling (parking lots, truck stops, rest areas, freight or bus terminals) 

• Rural Restricted Access (2) – rural highways that can only be accessed by an on-ramp 

• Rural Unrestricted Access (3) – all other rural roads (arterials, connectors, and local 

streets) 

• Urban Restricted Access (4) – urban highways or freeways that can only be accessed by 

an on-ramp 

• Urban Unrestricted Access (5) – all other urban roads (arterials, connectors, and local 

streets) 

Users should select the road types present in the area being analyzed. The determination of rural 

or urban road types should be based on the HPMS classification of the roads in the county being 

analyzed. 

The NCDAQ followed the USEPA guidance that states that all SIP and regional conformity 

analyses must include the Off-Network road type in order to account for emissions from vehicle 

starts, extended idle activity, and evaporative emissions (for VOCs). The Off-Network road type 

is automatically selected when start or extended idle pollutant processes are chosen and must be 

selected for all evaporative emissions to be quantified. Off-Network activity in MOVES is 

primarily determined by the Source Type Population input, which is described in Section 4.2.9 of 

this document. Some evaporative emissions are estimated on roadways (i.e., roadtypes 2, 3, 4, 

and 5) to account for evaporative emissions that occur when vehicles are driving. All roads 

types are automatically selected when Refueling emission processes are selected. 
On-road Mobile Sources Documentation 18 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

MOVES uses Road Type to assign default drive cycles to activity on road types 2, 3, 4, and 5. 

For example, for unrestricted access road types, MOVES uses drive cycles that assume stop and 

go driving, including multiple accelerations, decelerations, and short periods of idling. For 

restricted access road types, MOVES uses drive cycles that include a higher fraction of cruise 

activity with less time spent accelerating or idling, although some ramp activity is also included. 

4.2.7 Pollutants and Processes 

In MOVES, pollutant refers to particular types of pollutants or precursors of the pollutant, such as 

NOx or VOCs, while process refers to the mechanism by which emissions are created, such as 

running exhaust or start exhaust. Users must select all processes associated with a particular 

pollutant in order to account for all emissions of that pollutant. For example, there are 11 separate 

pollutant processes in MOVES for VOC, or hydrocarbon, emissions; all 11 must be selected when 

estimating VOC emissions for SIPs or regional conformity analyses. For this maintenance plan the 

pollutants under consideration were NOx and VOC. 

4.2.8 Temperature, Relative Humidity and Barometric Pressure Assumptions 

Local temperature and humidity data are required inputs for SIP and regional conformity analyses 

with MOVES. Ambient temperature is a key factor in estimating emission rates for on-road vehicles 

with substantial effects on most pollutant processes. Relative humidity is also important for 

estimating NOx emissions from motor vehicles. MOVES requires a temperature (in degrees 

Fahrenheit) and relative humidity (in percent – 0 to 100 scale) for each hour selected in the Run 

Spec. For example, MOVES requires a 24-hour temperature and humidity profile to model a full day 

of emissions on an hourly basis. For mobile source emission estimates, the NCDAQ used 2007 

July monthly averages for the 24-hour temperature and relative humidity profiles from the Triad 

Regional Airport (GSO) for Davidson, Davie, Forsyth, and Guilford Counties. Data were 

obtained North Carolina State Climate Retrieval and Observations Network of the Southeast 

Database (CRONOS). The temperature and relative humidity profiles as presented in the 

MOVES input files are listed in section 5.2. 

4.2.9 Source Type Population 

Source type (i.e., vehicle type) population is used by MOVES to calculate start and evaporative 

emissions. In MOVES, start and resting evaporative emissions are related to the population of 

vehicles in an area. Since vehicle type population directly determines start and evaporative 

emission, users must develop local data for this input. 

MOVES uses a vehicle classification system based on the way vehicles are classified in the Federal 

Highway Administration’s HPMS rather than on the way they are classified in EPA emissions 
On-road Mobile Sources Documentation 19 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

regulations; thus making it easier for users to develop local data for MOVES. MOVES categorizes 

vehicles into 13 source types, which are subsets of 6 HPMS vehicle types in MOVES, as shown 

in the crosswalk in Table 4.2.9-1. The USEPA believes that states should be able to develop 

population data for many of these source type categories from state motor vehicle registration 

data (e.g., motorcycles, passenger cars, passenger trucks, light commercial trucks) and from local 

transit agencies, school districts, bus companies, and refuse haulers (intercity, transit, and school 

buses, and refuse trucks). The NCDOT supplied the NCDAQ with source population data as 

described in the following section.

Source Type Population – Local Data

MOVES uses allocation factors to distribute emissions and activity (such as vehicle type 

populations) to individual counties. The NCDAQ is committed to using representative local data 

which will over ride MOVES default values through the County Data Manager. This decision 

was based on the fact that default allocation factors used in MOVES are derived from the VMT. 

Since the allocations are based on VMT, the vehicle populations allocated to counties are 

proportional to the VMT being allocated to that county. The NCDAQ corresponded with 

USEPA Office of Transportation and Air Quality (OTAQ) to arrive at an acceptable method to 
On-road Mobile Sources Documentation 20 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

allocate current year as well as to project future year vehicle populations to source type 

populations. The NCDAQ believes that using MOVES default vehicle population to estimate a 

fraction is the best method of taking state specific vehicle registration data and allocating county 

total vehicles to specific vehicle source types. 

MOVES categorize vehicles into 13 source types, which are subsets of 6 HPMS vehicle types. 

Presently NCDAQ is unable to develop county source type population data for many of these 

source type categories based on how NCDOT collect vehicle registration data. The latest vehicle 

registration data broken down by county and towns is available by January of each year. Since 

the vehicle types database available from NCDOT differs from what MOVES2010a expects, the 

NCDAQ relies on MOVES default fractions and applies these fractions to county total vehicle 

population, minus trailers. It is assumed that trailers do not have engines and do not generate 

VMT. 

For future year MOVES runs, the NCDAQ needed to be able to grow the vehicle population 

reflective of the county of interest. From FHWA Highway Statistics graph of Licensed Drivers, 

Vehicle Registrations, and Resident Population, the NCDAQ has determined that growth in 

human population is a better indicator of growth in vehicle ownership as compared to VMT 

growth. 

Figure 4.2.9-1 Federal Highway Association Statistics Graph 

In order to forecast future year vehicle population and disaggregate to the appropriate source 

type, a reliable source of county population is needed. The North Carolina Office of State 

Budget and Management (OSBM) coordinates with the Census in the Federal State Cooperative 
On-road Mobile Sources Documentation 21 

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

Program for population estimates for all state government data, with special emphasis on a 

consistent set of population projections. On OSBM website are annual certified county 

population estimates which account for births, deaths and natural growth representing a net 

migration populous at the county level. 

Population data is updated annually in May and certified by September for the previous year’s 

data. Projected annual county population estimates are available to adjust future year county 

vehicle populations as needed. The USEPA has indicated that using human population growth as 

a surrogate to project vehicle population growth is an acceptable option. An example of how a 

2008 vehicle population would be grown to 2011 based on this surrogate of projected county 

population follows: 

Vehicle Pop 2011 = Vehicle Pop 2008 * (Human Pop 2011/ Human Pop 2008)

4.2.10 Vehicle Inspection and Maintenance Program Assumptions 

In 2002, North Carolina implemented a new vehicle emissions inspection program referred to as 

onboard diagnostics (OBDII). This program covers all light duty gasoline powered vehicles that 

are model year 1996 and newer. The program was initially implemented in 9 counties and was 

expanded to include a total of 48 counties between July 2002 and January 2006. Forsyth and 

Guilford Counties were phased in July 2002. Davidson was phased-in July 1, 2003. 

Inspection and maintenance programs continue to be important local control programs in many 

nonattainment areas. MOVES includes the capability of modeling all the aspects of an I/M 

program that have a significant impact on vehicle emissions. The USEPA recommends that 

users modeling an existing I/M program in MOVES begin by examining the default I/M program 

description included in MOVES for the particular county in question. The NCDAQ modified the 

default data in MOVES to reflect county specific compliance factors. 

4.2.11 Reid Vapor Pressure Assumptions 

The Reid Vapor Pressure (RVP) reflects a gasoline’s volatility. An RVP of 7.8 pounds per 

square inch is required in July for the Triad 1-hour maintenance counties. 

4.2.12 Diesel Sulfur Content Assumptions 

The diesel fuel sulfur content is required in MOVES to generate fine particulate matter emission 

factors because the amount of sulfur in diesel fuel directly correlates to sulfate particulate

Greensboro/Winston-Salem/High Point area Appendix B.3 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

emissions. The USEPA recommends a diesel fuel sulfur content of 43 parts per million (ppm) 

for the period June 2006-May 2010 and 11 ppm for June 2010 -2015. 

4.2.13 Fuel (Formulation and Supply) 

In general, users should first review the MOVES default fuel formulation and fuel supply data, 

and then make changes only where local volumetric fuel property information is available. The 

lone exception to this guidance is in the case of RVP where a user should change the value to 

reflect the regulatory requirements and differences between ethanol- and non-ethanol blended 

gasolines. The current version of MOVES does not allow the user to create new fuel 

identification numbers. Thus, per current the USEPA guidance, the NCDAQ edited the default 

fuel supply tables for the individual counties to reflect the county-specific RVP data.

4.2.14 VMT Assumptions 

As input, MOVES requires annual VMT by HPMS vehicle class. The USEPA has created a tool 

that allows users to input average annual daily VMT as well as monthly and weekend day 

adjustment factors to create the annual VMT by HPMS class and appropriate monthly and daily 

adjustments needed by MOVES. The USEPA has also created a set of software tools that can 

import VMT tables by MOBILE6.2 vehicle types (either 8, 12, 16, or 28 MOBILE6.2 vehicle 

types) and facility types, as well as MOBILE6.2 hourly VMT fractions, VMT mix, and ramp 

fractions and convert these to the equivalent MOVES tables of VMT by HPMS class, VMT 

fractions by hour, and road type distribution. Mapping MOBILE6.2 vehicle types to their 

equivalent MOVES source types is a complex process. The USEPA strongly encourages states 

to use the converter tools to create the appropriate MOVES input tables from MOBILE6.2 data 

to avoid errors. 

The VMT for Davidson, Forsyth, and Guilford Counties was provided by PART. The NCDAQ 

used HPMS VMT, provided by NCDOT, for Davie County. Tables 4.3-1 through 4.3-5 list the 

daily VMT used in the emissions calculations.

1.0 INTRODUCTION AND SCOPE 

Nonroad mobile sources are equipment that can move but are not licensed to use the public roads 

and highways. The nonroad mobile source category includes a diverse collection of equipment 

such as lawn mowers, chain saws, tractors, all terrain vehicles, forklifts and construction 

equipment. Emissions from this equipment are calculated using the NONROAD model 

developed by the United States Environmental Protection Agency (USEPA). This category also 

includes aircraft, railroad locomotives, and commercial marine vessels. No commercial marine 

vessels operate in Davidson, Davie, Forsyth, or Guilford counties so there are no emissions 

reported for this category. 

For this maintenance demonstration, emissions of oxides of nitrogen (NOx) and volatile organic 

compounds (VOC) were estimated for the base year of 2007 and future years of 2011 and 2018. 

2.0 OVERALL METHODOLOGY 

2.1 SOURCE CATEGORY IDENTIFICATION 

Nonroad mobile sources were identified using the USEPA guidance document EPA-450/4-91-

016, Procedures for the Preparation of Emissions Inventories for Carbon Monoxide and 

Precursors of Ozone (Procedures document). Nonroad mobile source emissions are estimated by 

the methodologies suggested in the USEPA document, EPA-454/R-05-001, Emissions Inventory 

Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality 

Standards (NAAQS) and Regional Haze Regulations; EPA-450/4-81-026d (Revised) Procedures 

for Emission Inventory Preparation, Volume IV; Mobile Sources (Mobile Source Procedures); 

from the USEPA’s nonroad mobile model NONROAD2008a released July 6, 2009; and from the 

EDMS5.0 model developed by the USEPA and the Federal Aviation Administration (FAA). 

2.2 EMISSION ESTIMATION APPROACH 

For the majority of nonroad categories, emissions were estimated using the USEPA’s 

NONROAD2008a model. Model runs were performed for each of the four counties for each of 

the three years. The model runs were developed for a typical July weekday. 

Aircraft emissions for 2007 were obtained from E.H. Pechan & Associates, Inc. (Pechan) work 

to develop a modeling inventory for the Southeastern States Air Resource Managers, Inc. 

(SESARM). Pechan started with the 2008 aircraft emission inventory developed by the EPA for 

the National Emissions Inventory (NEI) and backcast it with growth factors derived from activity 

data in the Federal Aviation Administration’s (FAA) Air Traffic Activity Data System 

(ATADS). Pechan also incorporated emissions for military aircraft developed by the North 

Carolina Division of Air Quality (NCDAQ) to replace the USEPA estimates for military aircraft 

at civilian airports. 
Nonroad Mobile Sources Documentation 2 

Greensboro/Winston-Salem/High Point area Appendix B.4 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

Growth factors to estimate emissions for 2011 and 2018 were developed by the NCDAQ using 

operations counts from the FAA’s Terminal Area Forecast (TAF). 

Railroad emissions for 2007 (Class I, II, III, and railyards) were produced by Pechan by growing 

an inventory developed by the Eastern Regional Technical Advisory Committee (ERTAC) for 

the 2008 NEI. Passenger railroad emissions were developed by the NCDAQ for 2007. Growth 

factors were based on projected railroad fuel use. Future emission reductions due to emission 

control measures were calculated based on future emission factors published in the USEPA 

document Emission Factors for Locomotives, EPA-420-F-09-025. 

3.0 QUALITY ASSURANCE MEASURES 

For the NONROAD model runs, the options files (files that display the variables used to setup a 

model run) were reviewed by a second person who did not perform the actual runs. The model 

results were also evaluated by comparing one county to another to see that the results were 

reasonable after taking into consideration the differences between the counties. 

Information about the quality assurance measures taken by the USEPA in developing the 2008 

aircraft inventory may be found in USEPA documentation. E.H. Pechan provides information 

about their quality assurance measures in their document for SESARM titled Area and Nonroad 

2007 Base Year Inventories Final Report, contract No. S-2009-06-01 (Appendix C). 

The 2008 emission estimates for aircraft were developed under quality assurance procedures 

required by the USEPA for the NEI. For military aircraft at civilian airports, the NCDAQ 

developed emission factors based on surveys of military aircraft operations at military airports in 

the State. These factors were derived from operations counts and emissions calculated using the 

Emission and Dispersion Modeling System version 5.1.2 (EDMS) was carefully reviewed. 

Growth factors were calculated using data provided by the Federal Aviation Administration. 

4.0 EMISSIONS AND DETAILED METHODOLOGY 

4.1 CATEGORIES FROM THE NONROAD MODEL 

The USEPA included more than 80 different types of equipment in the NONROAD model. To 

facilitate analysis and reporting, the USEPA grouped the equipment types into eleven equipment 

categories. These include: 

Agricultural equipment Lawn and garden equipment, commercial 

Commercial equipment Logging equipment 

Construction and mining equipment Pleasure craft (recreational marine) 

Industrial equipment Railroad maintenance equipment 

Lawn and garden equipment, residential Recreational equipment 
Nonroad Mobile Sources Documentation 3 

Greensboro/Winston-Salem/High Point area Appendix B.4 

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

The eleventh category, aircraft ground support equipment, was not calculated with the 

NONROAD model because the method of calculation performed by the EDMS model was 

judged to be superior. Additionally, the emissions are estimated for five different engine types. 

These include: 2-stroke and 4-stroke spark ignition engines, diesel engines, liquid propane gas 

and compressed natural gas fueled engines. 

The NONROAD2008a model version was used to estimate emissions for the maintenance plan. 

This latest version of the model was released to the public on July 6, 2009. 

NONROAD2008a is the latest release of the USEPA NONROAD model that was first released 

in June 2000, and incorporates many revisions to improve the model’s predictive ability. 

Compared to NONROAD2005c, this model revision accounts for emission reductions from the 

Diesel Recreational Marine standards in the Loco/Marine final rule published in the Federal 

Register (FR) (73FR 25098) and the Small Spark Ignition and Spark Ignition Recreational 

Marine final rule (FR 59034). There are a number of additional improvements including the 

ability to model the effects of ethanol blends on fuel tank and hose permeation losses. 

The options files (wherein all the modeling variables are set) used in the NONROAD2008a 

model were tailored to reflect North Carolina specific information. Copies of the options input 

files are in Section 6.0 of this document. The model was run for a typical July weekday for the 

years 2007, 2011, and 2018. The seasonal file for the model was modified to place North 

Carolina in the Southeast states group rather than the Mid-Atlantic group. This change was 

made because the NCDAQ had reviewed temperature data of North Carolina compared to states 

in the Southeast and the Mid-Atlantic. The results of this comparison indicated that North 

Carolina temperatures are more in-line with the Southeast States. Future year estimates of fuel 

oxygen (due to Federal ethanol mandates) and fuel sulfur (due to the USEPA requirements) were 

incorporated. Default data was used for the remaining input files used in the NONROAD model. 

For reporting purposes, the resulting emissions from the NONROAD2008a model were totaled 

for each equipment category by county. The results for most of the equipment categories by 

county indicate a reduction in emissions with time into the future years. These reduced emission 

projections are influenced by several factors, including expected future changes in engine 

standards, fuel specifications, scrappage of old equipment, and activity levels. These future 

engine standards and activity levels are accounted for in the model. 

The summary of the model results expressed in tons emitted per typical July weekday are 

tabulated in Table 4-1 through Table 4-10.

4.2 AIRCRAFT ENGINES AND AIRPORT GROUND SUPPORT 

Aircraft engines, like other engines, emit pollutants whenever the engines are in operation. 

However, the only emissions that are of concern for this inventory are the portion of the 

operation that occurs below the mixing layer. This is because the emissions tend to disperse 

whenever the aircraft is above the mixing layer and therefore have little or no effect on ground 

level air pollutant concentrations. 

The aircraft emissions of interest are produced during the landing and takeoff (LTO) cycle. The 

cycle begins when the aircraft approaches the airport, descending below the mixing layer, lands 

and taxis to the gate. It continues as the aircraft idles at the gate and then taxis back out to the 

runway for the subsequent takeoff and climb out as it heads back to cruising altitudes, above the 

mixing layer. Associated with these emissions are emissions from ground support equipment 

(GSE) and auxiliary power units (APU). 

Aircraft can be categorized by use into four classifications: commercial, air taxis, general 

aviation and military. Commercial aircraft include those used for scheduled service transporting 

passengers, freight or both. Air taxis and commuter aircraft also fly scheduled service carrying 

passengers and/or freight but usually are smaller aircraft and operate on a more limited basis than 

commercial carriers. Air taxis may also be used for unscheduled on-demand flights. General 

aviation includes all other non-military aircraft used for recreational flying, personal 

transportation, and various other activities. Military aircraft cover a wide range of sizes, uses, 

and operating missions. Military operations at civilian airports (as in the Triad) are often 

associated with National Guard, Army Reserve, and Air Force Reserve training.

110(a)(1) Maintenance Plan for 8-hour ozone April 13, 2011 

Emission estimates were developed by the USEPA for year 2008 for all airports in North 

Carolina as part of the National Emission Inventory. Emission calculations for commercial 

aircraft were made using the EDMS 5.1 model developed by the USEPA and the Federal 

Aviation Administration (FAA). Emissions for air taxi and general aviation (both subgrouped 

into piston engine and turbine engine categories) were made using emission factors developed by 

the EPA working with the FAA. More detail about this process is found in Documentation for 

Aircraft Component of the National Emissions Inventory Methodology, ERG No.: 

0245.02.302.001, Contract No.: EP-D-07-097 prepared by Eastern Research Group under 

contract to E.H. Pechan for the EPA. For military operations at civilian airports, emissions were 

calculated using emission factors developed by NCDAQ from surveys of military airports in 

North Carolina. 

Emissions for aircraft operations in Davidson, Davie, Guilford, and Forsyth counties were 

projected from 2008 to the maintenance plan year 2007 by Pechan using backcasting factors 

developed from the FAA’s ATADS data. Factors to project to 2011 and 2018 were developed 

by the NCDAQ using activity projections from the FAA’s Terminal Area Forecast (TAF) for 

North Carolina. The TAF estimates future activity at three airports in the four county area. 

Growth factors specific to these airports were developed. Composite factors were developed 

from these three airports’ estimates and applied to the other small airports in the four Triad 

counties. The EDMS model calculates emissions from ground support equipment and emissions 

from auxiliary power units (APU) both associated with certain aircraft. Ground support 

equipment consists of equipment such as tractors used to tow airplanes to the gate or catering 

trucks that bring food to large airliners. APUs are typically smaller engines on aircraft that 

provide power for electricity or air conditioning when the main engines are shut off.

4.3 RAILROAD LOCOMOTIVES 

Railroad companies are categorized by size (Class I, Class II, or Class III) and passenger service 

(Amtrak and NCDOT Rail Division). Class I railroad companies are long haul operations, 

consisting of Norfolk Southern Corporation and CSX Corporation. Class II and Class III 

railroad companies are short lines serving localized markets. Amtrak and the NCDOT Rail 

Division provide passenger service. 

Railroad locomotive emissions for classes I, II, and III plus rail yards were calculated for all of 

North Carolina for 2007 by E.H.Pechan as part of the 2007 base year inventory prepared for 

SESARM. The Pechan inventory was prepared based on the ERTAC inventory developed for the 

2008 National Emission Inventory. Some of the details of the ERTAC work are based on 

proprietary information provided by the railroad companies. The calculation methodologies 

followed procedures acceptable to the EPA. Additional detail can be found in the SESARM 

document Area and Nonroad 2007 Base Year Inventories Final Report, contract No. S-2009-06-

01. 

Passenger railroad emissions were developed by NCDAQ for 2007. This was done using 

information supplied by the North Carolina Department of Transportation and emission factors 

from Emission Factors for Locomotives, EPA-420-F-09-025. Railroad emissions are shown in 

Table 4- 13 below:

5.0 PROJECTION AND CONTROL FACTORS 

5.1 AIRCRAFT EMISSIONS GROWTH 

Factors to grow aircraft emissions were produced by running the FAA’s Terminal Area Forecast 

model to produce estimates of aircraft operations for 2007, 2011, and 2018 as described above. 

For the three airports in the four counties that appear in the TAF, growth factors unique to each 

of these airports were produced. For the rest of the airports in the four counties composite growth 

factors were produced from the three. The projection factors are shown in Table 5- 1 below.

Control factors shown in the following table were calculated by using recommended emission 

factors for NOX and hydrocarbons (virtually the same as VOC) from Emission Factors for 

Locomotives, EPA-420-F-09-025. The control factors were calculated by dividing base year 

emission factors by the future year emission factors. Improving control factors are due to 

requirements for reduced emissions from new and rebuilt locomotive diesel engines. Future 

emissions were calculated by multiplying the base year emissions by the associated growth 

factor and by the associated control factor.

This is the options file for the NONROAD program. 

The data is sperated into "packets" bases on common 

information. Each packet is specified by an 

identifier and a terminator. Any notes or descriptions 

can be placed between the data packets.

 PERIOD PACKET 

This is the packet that defines the period for 

which emissions are to be estimated. The order of the 

records matter. The selection of certain parameters 

will cause some of the record that follow to be ignored. 

The order of the records is as follows: 

1 - Char 10 - Period type for this simulation. 

 Valid responses are: ANNUAL, SEASONAL, and MONTHLY 

2 - Char 10 - Type of inventory produced. 

 Valid responses are: TYPICAL DAY and PERIOD TOTAL 

3 - Integer - year of episode (4 digit year) 

4 - Char 10 - Month of episode (use complete name of month) 

5 - Char 10 - Type of day 

 Valid responses are: WEEKDAY and WEEKEND

The first record tells the type of region and 

allocation to perform. 

Valid responses are: 

US TOTAL - emissions are for entire USA without state 

 breakout. 

50STATE - emissions are for all 50 states 

 and Washington D.C., by state. 

STATE - emissions are for a select group of states 

 and are state-level estimates 

COUNTY - emissions are for a select group of counties 

 and are county level estimates. If necessary, 

 allocation from state to county will be performed. 

SUBCOUNTY - emissions are for the specified sub counties 

 and are subcounty level estimates. If necessary, 

 county to subcounty allocation will be performed. 

The remaining records define the regions to be included. 

The type of data which must be specified depends on the 

region level. 

US TOTAL - Nothing needs to be specified. The FIPS 

 code 00000 is used automatically. 

50STATE - Nothing needs to be specified. The FIPS 

 code 00000 is used automatically. 

STATE - state FIPS codes 

COUNTY - state or county FIPS codes. State FIPS 

 code means include all counties in the

 SOURCE CATEGORY PACKET 

This packet is used to tell the model which source 

categories are to be processed. It is optional. 

If used, only those source categories list will 

appear in the output data file. If the packet is 

not found, the model will process all source 

categories in the population files.
