1. INTRODUCTION 

The attainment modeling for the Charlotte-Gastonia-Rock Hill, North Carolina-South Carolina 

8-hour ozone nonattainment area (referred to as the Metrolina area) was performed in 

conjunction with the regional haze modeling being done by the Southeast Regional Planning 

Organization, Visibility Improvement State and Tribal Association of the Southeast (VISTAS) 

and the fine particulate matter (PM2.5) and ozone modeling being done by the Association of 

Southeastern Integrated Planning (ASIP). VISTAS and ASIP are run by the ten Southeast states 

(Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, 

Virginia and West Virginia). Since the regional haze and PM2.5 modeling uses annual 

simulations and includes an intermediate year that is the attainment year required for the 

Metrolina nonattainment area, the North Carolina Division of Air Quality (NCDAQ) decided to 

use the this modeling for its attainment demonstration. 

Although the VISTAS/ASIP developed emission estimates for all pollutants of concern for 

regional haze, fine particulate matter and ozone, only the emissions inventory discussions 

relevant to ozone formation, i.e., nitrogen oxides (NOx) and volatile organic compounds 

(VOCs), will be discussed in this document. The other pollutants will be discussed in detail in 

the regional haze and fine particulate matter State Implementation Plans (SIPs). 

2. 2002 POINT SOURCE INVENTORY DEVELOPMENT 

This section details the development of the 2002 base year inventory for point sources. There 

were two major components to the development of the point source sector of the inventory. The 

first component was the incorporation of data submitted by State and Local (S/L) agencies to the 

United States Environmental Protection Agency (USEPA) as part of the Consolidated Emissions 

Reporting Rule (CERR) requirements. Work on incorporating the CERR data into the revised 

base year involved: 1) obtaining the data from the USEPA or the S/L agencies, 2) evaluating the 

emissions and pollutants reported in the CERR submittals, 3) augmenting CERR data with 

annual emission estimates for primary coarse particulate matter (PM10-PRI) and PM2.5-PRI; 

4) evaluating the emissions from electric generating units, 5) completing quality assurance 

reviews for each component of the point source inventory, and 6) updating the database with 

corrections or new information from S/L agencies based on their review of the 2002 inventory. 

This document will not address the augmenting of the particulate matter since these pollutants 

are not considered an ozone precursor. The remaining processes used to perform the emission 

inventory development are described in the first portion of this section. 
Point Source Documentation 2 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

The second component was the development of a “typical” year inventory for electric generating 

units (EGUs). The VISTAS/ASIP states determined that a typical year EGU inventory was 

necessary to smooth out any anomalies in emissions from the EGU sector due to meteorology, 

economic, and outage factors in 2002. This is consistent with the USEPA’s guidance for SIP 

modeling. The typical year EGU inventory is intended to represent the five-year (2000-2004) 

period that will be used for the attainment demonstration for the PM2.5 and ozone SIPs, and to 

determine the regional haze reasonable progress goals. The second part of this section discusses 

the development of the typical year EGU inventory. 

A list of sources located in the Metrolina nonattainment area, as well as the average daily peak 

ozone season emissions can be found in Appendix E. 

2.1 Development of 2002 Actual Point Source Inventory 

VISTAS/ASIP contracted with MACTEC to develop the 2002 emission inventory. NCDAQ

submitted the most updated statewide emission inventory to the contractor with the exception of 

the emissions from the three local programs. For the three local programs, Forsyth, 

Mecklenburg, and Buncombe Counties, the CERR submittal from the USEPA was used. Once 

all of the files were obtained, MACTEC ran the files through the USEPA’s Nationa Emissions 

Inventory (NEI) Input Format (NIF) Basic Format and Content checking tool to ensure that the 

files were submitted in standard NIF format and that there were no referential integrity issues 

with those files. 

The primary task in preparing the 2002 base year inventory was the incorporation of corrections 

and new information as submitted by the S/L agencies based on their review of the previous draft 

versions of the inventory. The following subsections document the data sources for the 

inventory, the checks made on the CERR submittals, the evaluation of EGU emissions, and other 

quality assurance/quality control (QA/QC) checks. The final subsection summarizes the 2002 

NOx and VOC inventory by sector (EGU and non-EGU). 

Throughout the development of the point source emissions inventory, the NCDAQ completed 

detailed reviews of the inventories prepared by the VISTAS/ASIP contractor and provided 

comments and data corrections when needed. 

2.1.1 Consolidated Emissions Reporting Rule 

The CERR was published in the Federal Register on Monday, June 10, 2002 (FR Volume 67, 

Number 111, pp 39602 - 39616). This brief summary is provided as a quick introduction to the 

CERR and covers the major items in the rule. 
Point Source Documentation 3 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

The purpose of the CERR is to simplify reporting, offer options for data collection and exchange, 

and unify reporting dates for various categories of criteria pollutant emission inventories. The 

rule applies to S/L agencies. Previous reporting requirements have, at times, forced reporting 

agencies into inefficient collecting and reporting activities. This rule consolidates the emission 

inventory reporting requirements found in various parts of the Clean Air Act (CAA). 

Consolidation of reporting requirements will enable S/L agencies to better explain to program 

managers and the public the necessity for a consistent inventory program, increases the 

efficiency of the emission inventory program, and provide more consistent and uniform data. 

States are required to prepare a comprehensive statewide inventory every three years. The first 

inventory was for the year 2002 and was due June 1, 2004. This CERR inventory was used for 

the VISTAS/ASIP 2002 base year.

2.1.2 EGU Analysis 

MACTEC made a comparison of the annual sulfur dioxide (SO2) and NOx emissions for EGUs 

as reported in the S/L agencies CERR submittals and the data from the USEPA’s Clean Air 

Markets Division (CAMD) continuous emission monitoring (CEM) database to identify any 

outstanding discrepancies. Facilities report hourly CEM data to the USEPA for units that are 

subject to CEM reporting requirements of the NOx SIP Call rule and Title IV of the CAA. The 

USEPA sums the hourly CEM emissions to the annual level, and MACTEC compared these 

annual CEM emissions to those in the S/L inventories. The 2002 CEM inventory containing 

NOx and SO2 emissions and heat input data were downloaded from the USEPA CAMD web site 

(www.epa.gov/airmarkets). The data were provided by quarter and emission unit. 

The first step in the EGU analysis involved preparing a crosswalk file to match facilities and 

units in the CAMD inventory to facilities and units in the S/L inventories. In the CAMD 

inventory, the Office of Regulatory Information Systems (ORIS) identification (ID) code 

identifies unique facilities and the unit ID identifies unique boilers and internal combustion 

engines (i.e., turbines and reciprocating engines). In the North Carolina point source emissions 

inventories, the State and county code (FIPS code) and State facility ID together identify unique 

facilities and the emission unit ID identifies unique boilers or internal combustion engines. In 

most cases, there is a one-to-one correspondence between the CAMD identifiers and the S/L 

identifiers. However, in some of the S/L inventories, the emissions for multiple emission units 

are summed and reported under one emission unit ID. MACTEC created an Excel spreadsheet 

that contained an initial crosswalk with the ORIS ID and unit ID in the CEM inventory matched 

to the State and county FIPS, State facility ID, and emission unit ID in the emissions inventories. 

The initial crosswalk contained both the annual emissions summed from the CAMD database, as 
Point Source Documentation 4 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

well as, the S/L emission estimate. The matching at the facility level was nearly complete. In 

some cases, however, S/L agencies or stakeholders’ assistance was needed to match some of the 

CEM units to emission units in the S/L inventories. 

The second step in the EGU analysis was to prepare an Excel spreadsheet that compared the 

annual emissions from the hourly CAMD inventory to the annual emissions reported in the S/L 

inventory. The facility-level comparison of CEM to emission inventory NOx and SO2 emissions 

found that for most facilities, the annual emissions from the S/L inventory equaled the CAMD 

CEM emissions. Minor differences could be explained because the facility in the S/L inventory 

contained additional small or emergency units that were not included in the CAMD database. 

The final step in the EGU analysis was to compare the SO2 and NOx emissions for select 

Southern Company units in the VISTAS/ASIP region. Southern Company is a super-regional 

company that owns EGUs in four VISTAS/ASIP States – Alabama, Florida, Georgia, and 

Mississippi – and participates in VISTAS as an industry stakeholder. Southern Company 

independently provided emission estimates for 2002 as part of the development of the 

preliminary VISTAS 2002 inventory. Emission estimates were reviewed by the States and 

incorporated into the States CERR submittal. There were no major inconsistencies between the 

Southern Company data, the CAMD data, and the S/L CERR data. 

The minor inconsistencies found included small differences in emission estimates (<2 percent 

difference), exclusion/inclusion of small gas-fired units in the different databases, and grouping 

of emission units in S/L CERR submittals where CAMD listed each unit individually. MACTEC 

compared SO2 and NOx emissions on a unit-by-unit basis and did not find any major 

inconsistencies. 

2.1.3 Summary of the 2002 Actual Inventory 

Tables 2.1.3-1 summarize the final 2002 actual base year inventory for North Carolina. All 

values are in tons per year. The EGU emissions include the emissions from all processes with a 

Source Classification Code (SCC) of either 1-01-xxx-xx (External Combustion Boilers – Electric 

Generation) or 2-01-xxx-xx (Internal Combustion Engines – Electric Generation). Emissions for 

all other SCCs are included in the non-EGU column.

2.2 Development of Typical Year EGU Inventory 

VISTAS/ASIP developed a typical year 2002 emission inventory for EGUs to avoid anomalies 

in emissions due to variability in meteorology, economic, and outage factors in 2002. The 

typical year inventory represents the five year (2000-2004) period, which are the years used to 

calculate the average design value. 

Data from the USEPA’s CAMD were used to develop normalization factors for producing a 

2002 typical year inventory for EGUs. The VISTAS/ASIP contractor used the ratio of the 

2000-2004 average heat input and the 2002 actual heat input to normalize the 2002 actual 

emissions. MACTEC obtained data from the USEPA CAMD for utilities regulated by the Acid 

Rain program. Annual data for the period 2000 to 2004 were obtained from the CAMD web site. 

The parameters available were the SO2 and NOx emission rates, heat input, and operating hours. 

MACTEC used the actual 2002 heat input and the average heat input for the 5-year period from 

2000-2004 as the normalization factor, as follows: 

Normalization Factor: 2000-2004 average heat input 

 2002 actual heat input

If the unit did not operate for all five years, then the 2000-2004 average heat input was calculated 

for the one or two years in which the unit did operate. The annual actual emissions were 

multiplied by the normalization factor to determine the typical emissions for 2002, as follows: 
Point Source Documentation 6 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

Typical Emissions = 2002 actual emissions x Normalization Factor 

After applying the normalization factor, some adjustments were needed for special 

circumstances. For example, a unit may not have operated in 2002 and thus have zero emissions. 

If the unit had been permanently retired prior to 2002, then MACTEC used zero emissions for 

the typical year. If the unit had not been permanently retired and would normally operate in a 

typical year, then MACTEC used the 2001 (or 2000) heat input and emission rate to calculate the 

typical year emissions. 

The final step was to replace the 2002 actual emissions with the 2002 typical year data described 

above. MACTEC provided the raw data and results of the typical year calculations in a 

spreadsheet for S/L agency to review and comment. Any comments made were incorporated into 

the typical 2002 inventory. 

Table 2.2-1 summarizes emissions by State and pollutant for the actual 2002 EGU inventory and 

the typical year EGU inventory. For the entire VISTAS region, actual 2002 NOx emissions were 

about 0.1 percent lower than the typical year emissions. North Carolina’s actual 2002 NOx 

emissions were 2.0 percent higher than the typical year emissions.

3. 2009 POINT SOURCE EMISSIONS INVENTORY DEVELOPMENT 

Different approaches were used for different sectors of the point source inventory. For the 

EGUs, VISTAS/ASIP relied primarily on the Integrated Planning Model® (IPM) to project future 

generation, as well as, to calculate the impact of future emission control programs. The IPM 

results were adjusted based on S/L agency knowledge of planned emission controls at specific 

EGUs. For non-EGUs, VISTAS/ASIP used recently updated growth and control data consistent 

with the data used in the USEPA’s Clean Air Interstate Rule (CAIR) analyses, and supplemented 

these data with available S/L agency input and updated fuel use forecast data for the United 

States Department of Energy. 

For both sectors, VISTAS/ASIP generated 2009 inventory with control scenarios that account for 

post-2002 emission reductions from promulgated and proposed federal, State, local, and sitespecific control programs as of July 1, 2004. Section 3.1 discusses the EGU projection inventory 

development, while Section 3.2 discusses the non-EGU projection inventory development. 

3.1 EGU Emission Projections 

The following subsections discuss the aspects of the development of the EGU projections. 

• A chronology of the EGU development process used by MACTEC and discuss key 

decisions in selecting the final methods for performing the emissions projections. 

• The development of the final set of IPM runs that are included in the VISTAS/ASIP 

2009 inventory. 

• The process of transforming the IPM parsed files into NIF format. 

• The process for ensuring that units accounted for in IPM were not double-counted in 

the non-EGU inventory. 

• The QA/QC checks that were made to ensure that the IPM results were properly 

incorporated into the VISTAS/ASIP inventory. 

• The changes to the IPM results that S/L agencies requested be included in the 

VISTAS/ASIP inventory based on new information that was not accounted for in the 

IPM runs. 

• Summary of 2002 and 2009 EGU emissions by state for NOx and VOC 

3.1.1 Chronology of the Development of EGU Projections 

Initially, VISTASASIP considered three options for developing the 2009 projection inventory for 

EGUs: 
Point Source Documentation 8 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

• Option 1 – Use the results of IPM modeling conducted in support of the proposed CAIR 

base and control case analyses as the starting point and refine the projections with readily 

available inputs from stakeholders; these IPM runs were conducted for 2010, which 

VISTAS would use to represent projected emissions in 2009. 

• Option 2 – Use the VISTAS/ASIP 2002 typical year as the starting point, apply growth 

factors from the Energy Information Administration, and refine future emission rates with 

stakeholder input regarding utilization rates, capacity, retirements, and new unit 

information. 

• Option 3 – Use the results of a new round of IPM modeling sponsored by VISTAS and 

the Midwest Regional Planning Organization (MRPO). These runs incorporated 

VISTAS specific unit and regulation modified parameters, and generate results for 2009 

explicitly. 

An additional consideration for each of the three options was the inclusion of emission 

projections developed by the Southern Company specifically for their units. Southern Company 

is a super-regional company that owns EGUs in Alabama, Florida, Georgia, and Mississippi and 

participates in VISTAS as an industry stakeholder. Southern Company used their energy budget 

forecast to project net generation and heat input for every existing and future Southern Company 

EGU for the year 2009. Further documentation of how Southern Company generated the 2009 

inventory for their units can be found in Developing Southern Company Emissions and Flue Gas 

Characteristics for VISTAS Regional Haze Modeling (April 2005, presented at 14th International 

Emission Inventory Conference). 

Each of these three options and the Southern Company projections were discussed in a series of 

conference calls with the VISTAS EGU Special Interest Work Group (SIWG) during the fall of 

2004. During a conference call on December 6, 2004, the VISTAS EGU SIWG approved the 

use of the latest VISTAS/MRPO sponsored IPM runs (Option 3) to represent 2009 EGU 

forecasts of emissions the future year cases. 

The Option 3 IPM modeling resulted from a joint agreement by VISTAS and MRPO to work 

together to develop future year utility emissions based on IPM modeling. The decision to use 

IPM modeling was based in part on a study of utility forecast methods by E.H. Pechan and 

Associates, Inc. (Pechan) for MRPO, which recommended IPM as a viable methodology (see 

Electricity Generating Unit {EGU} Growth Modeling Method Task 2 Evaluation, February 11, 

2004). Although the USEPA used IPM recently to support their rulemaking for the CAIR, 

VISTAS stakeholders felt that certain model inputs needed to be improved. Thus, VISTAS and 
Point Source Documentation 9 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

MRPO decided to hire contractors to conduct new IPM modeling and to post-process the IPM 

results. Southern Company projections in 2009 were roughly comparable with IPM. 

In August 2004, VISTAS/ASIP contracted with ICF to run IPM to provide utility forecasts for 

2009 under two future scenarios – Base Case and CAIR Case. The Base Case represents the 

current operation of the power system under currently known laws and regulations, including 

those that come into force in the study horizon. The CAIR Case is the Base Case with the 

proposed CAIR rule superimposed. The run results were parsed at the unit level for 2009. The 

IPM output files were delivered by ICF in November, and the post-processed data files were 

delivered by Pechan in December 2004. Only the CAIR case was used in the final 2009 

modeling. 

On March 10, 2005, the USEPA issued the final CAIR. VISTAS and MRPO, in conjunction 

with other RPOs, conducted another round of IPM modeling, which reflected changes to control 

assumptions based on the final CAIR as well as additional changes to model inputs based on S/L 

agency and stakeholder comments. Several conference calls were conducted in the 

spring/summer of 2005 to discuss and provide comments on IPM assumptions related to six main 

topics: power system operation, generating resources, emission control technologies, set-up 

parameters and rule, financial assumptions, and fuel assumptions. 

For the summer 2006 set of IPM runs, ICF generated two different parsed files. One file 

includes all fuel burning units (fossil, biomass, landfill gas), as well as, non-fuel burning units 

(hydro, wind, etc.). The second file contains just the fossil-fuel burning units (e.g., emissions 

from biomass and landfill gas are omitted). The RPOs decided to use the fossil-only file for 

modeling to be consistent with the USEPA, since the USEPA used the fossil only results for 

CAIR analyses. For the 10 VISTAS states, non-fossil fuels accounted for only 0.13 percent of 

the NOx emissions and 0.04 percent of the SO2 emissions in the 2009 IPM runs 

VISTAS/ASIP asked S/L agencies to review the results of the summer 2006 set of IPM runs, 

which were incorporated into the VISTAS inventory. The NCDAQ primarily reviewed and 

commented on the IPM results with respect to IPM decisions on NOx post-combustion controls 

and SO2 scrubbers. 

3.1.2 VISTAS/MRPO IPM runs for EGU sources 

The following summary of the VISTAS/MRPO IPM® modeling is based on ICF’s 

documentation Future Year Electricity Generating Sector Emission Inventory Development 

Using the IPM® in Support of Fine Particulate Mass and Visibility Modeling in the VISTAS and 
Point Source Documentation 10 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

Midwest RPO Regions, April 2005. The ICF documentation is to be used as an extension to 

EPA's proposed CAIR modeling runs documented in Documentation Supplement for EPA 

Modeling Applications (V.2.1.6) Using the IPM, EPA 430/R-03-007, July 2003. 

IPM provides “forecasts of least-cost capacity expansion, electricity dispatch, and emission 

control strategies for meeting energy demand and environmental, transmission, dispatch, and 

reliability constraints.” The underlying database in this modeling is USEPA’s National Electric 

Energy Data System (NEEDS) released with the CAIR Notice of Data Availability (NODA). 

The NEEDS database contains the existing and planned/committed unit data in the USEPA 

modeling applications of IPM. NEEDS includes basic geographic, operating, air emissions, and 

other data on these generating units. VISTAS States and stakeholders provided changes for: 

• NOx post-combustion control on existing units 

• SO2 scrubbers on existing units 

• SO2 emission limitations 

• PM controls on existing units 

• Summer net dependable capacity 

• Heat rate for existing units 

• SO2 and NOx control plans based on State rules or enforcement settlements 

The years 2009 and 2018 were explicitly modeled in this set of runs. 

3.1.3 Post-Processing of IPM Parsed Files 

The following summary of the VISTAS/MRPO IPM modeling is based on Pechan’s 

documentation LADCO IPM Model Parsed File Post-Processing Methodology and File 

Preparation, February 8, 2005. The essence of the IPM model post-processing methodology is 

to take an initial IPM model output file and transform it into air quality model input files. ICF 

via VISTAS/MRPO provided an initial spreadsheet file containing unit-level records of both 

(1) “existing” units and (2) committed or new generic aggregates. 

All records have unit and fuel type data; existing, retrofit (for SO2 and NOx), and separate NOx 

control information; annual SO2 and NOx emissions and heat input; summer season (MaySeptember) NOx and heat input; July day NOx and heat input; coal heat input by coal type; 

nameplate capacity (MW), and State FIPS code. Existing units also have county FIPS code, a 

unique plant identifier (ORISPL) and unit ID (also called boiler ID) (BLRID); generic units do 
Point Source Documentation 11 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

not have these data. The processing includes estimating various types of emissions and adding in 

control efficiencies, stack parameters, latitude-longitude coordinates, and State identifiers (plant 

ID, point ID, stack ID, process ID). Additionally, the generic units are sited in a county and 

given appropriate IDs. This processing is described in more detail below. 

The data are prepared by transforming the generic aggregates into units similar to the existing 

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

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

and are given a county FIPS code based on an algorithm that sites each generic by assigning a 

sister plant that is in a county based on its attainment/nonattainment status. Within a State, 

plants (in county then ORIS plant code order) in attainment counties are used first as sister sites 

to generic units, followed by plants in PM2.5 nonattainment counties, followed by plants in 

8-hour ozone nonattainment counties. Note that no LADCO or VISTAS States provided 

blackout counties that would not be considered when siting generics, so this process is identical 

to the one used for the USEPA IPM post-processing. 

SCCs were assigned for all units; unit/fuel/firing/bottom type data were used for existing units’ 

assignments, while only unit and fuel type were used for generic units’ assignments. Latitudelongitude coordinates were assigned, first using the USEPA-provided data files, secondly using 

the September 17, 2004 Pechan in-house latitude-longitude file, and lastly using county 

centroids. These data were only used when the data were not provided in the 2002 NIF files. 

Stack parameters were attached, first using the USEPA-provided data files, secondly using a 

March 9, 2004 Pechan in-house stack parameter file based on previous EIA-767 data, and lastly 

using an USEPA June 2003 SCC-based default stack parameter file. These data were only used 

when the data were not provided in the 2002 NIF files. 

Additional data were required for estimating VOC, CO, filterable primary PM10 and PM2.5, PM 

condensable, and NH3 emissions for all units. Thus, ash and sulfur contents were assigned by 

first using 2002 EIA-767 values for existing units or SCC-based defaults; filterable PM10 and 

PM2.5 efficiencies were obtained from the 2002 EGU NEI that were based on 2002 EIA-767 

control data and the PM Calculator program (a default of 99.2 percent is used for coal units if 

necessary); fuel use was back calculated from the given heat input and a default SCC-based heat 

content; and emission factors were obtained from an USEPA-approved October 7, 2004 Pechan 

emission factor file based on AP-42 emission factors. Note that this updated file is not the one 

used for estimating emissions for previous USEPA post-processed IPM files. Emissions for 28 

temporal-pollutant combinations were estimated since there are seven pollutants (VOC, CO, 
Point Source Documentation 12

North Carolina Attainment Demonstration April 5, 2007 

primary PM10 and PM2.5, NH3, SO2 and NOx) and four temporal periods (annual, summer season, 

winter season, July day). 

The next step was to match the IPM unit IDs with the identifiers in VISTAS/ASIP 2002 

inventory. A crosswalk file was used to obtain FIPS State and county, plant ID (within State and 

county), and point ID. If the FIPS State and county, plant ID and point ID are in the 2002 

VISTAS NIF tables, then the process ID and stack ID are obtained from the NIF; otherwise, 

defaults, described above, were used. 

Pechan provided the post-processed files in NIF 3.0 format. Two sets of tables were developed: 

“NIF files” for IPM units that have a crosswalk match and are in the 2002 VISTAS inventory, 

and “NoNIF files” for IPM units that are not in the 2002 VISTAS inventory (which includes 

existing units with or without a crosswalk match as well as generic units). 

For the 2009 projections, VISTAS/ASIP states reviewed the PM and NH3 emissions from EGUs 

as provided by Pechan and identified significantly higher emissions in 2009 than in 2002. It was 

determined that Pechan used a set of PM and NH3 emission factors that are “the most recent 

USEPA approved uncontrolled emission factors” for estimating 2009 emissions. These factors 

are most likely not the same emission factors used by States for estimating these emissions in 

2002 for EGUs in the VISTAS/ASIP region. Thus, the emission increase from 2002 to 2009 was 

simply an artifact of the change in emission factor, not anything to do with changes in activity or 

control technology application. Also, VISTAS/ASIP states identified an inconsistent use of 

SCCs for determining emission factors between the base and future years. The resolution of the 

PM and NH3 problem is fully documented in EGU Emission Factors and Emission Factor 

Assignment, memorandum from Greg Stella to VISTAS State Point Source Contacts and 

VISTAS EGU Special Interest Workgroup, June 13, 2005 (attached in Appendix Q). The first 

step was the adjustment of the 2002 base year emissions inventory. Using the latest “USEPAapproved” uncontrolled emission factors by SCC, Alpine Geophysics utilized CERR or 

VISTAS/ASIP reported annual heat input, fuel throughput, heat, ash and sulfur content to 

estimate annual uncontrolled emissions for units identified as output by IPM. This step was 

conducted for non-CEM pollutants (CO, VOC, PM, and NH3) only. For PM emissions, the 

condensable component of emissions was calculated and added to the resulting PM primary 

estimations. The resulting emissions were then adjusted by any control efficiency factors 

reported in the CERR or VISTAS data collection effort. The second adjustment was to the 

future year inventories. Alpine Geophysics updated the SCCs in the future year inventory to 

assign the same base year SCC. Using the same methods as described for the 2002 revisions, 
Point Source Documentation 13 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

those non-IPM generated pollutants were estimated using IPM predicted fuel characteristics and 

base year 2002 SCC assignments.

3.1.4 S/L Adjustments to IPM Modeling Results 

After the S/L agency review of the final set of IPM runs, S/L agencies specified a number of 

changes to the IPM results to better reflect current information on when and where future 

controls would occur. These changes to the IPM results primarily involved S/L agency addition 

or subtraction of future emission controls based on the best available data from state rules, 

enforcement agreements, compliance plans, permits, and discussions/commitments from 

individual companies. 

For example,Duke Energy and Progress Energy have updated their plans for complying with 

North Carolina’s Clean Smokestack Act. The emissions outlined in the North Carolina’s Clean 

Smokestacks Act compliance plans varied substantially from the IPM results. As a result, 

NCDAQ requested that the IPM emission projections for 2009 be adjusted to correspond with 

the compliance plans submitted in 2006 from the Duke Energy and Progress Energy. 

Some S/L agencies specified changes to the controls assigned by IPM to reflect their best 

estimates of emission controls. The VISTAS/ASIP contractors used a scrubber control 

efficiency of 90 percent when adding or removing SO2 scrubber controls, used a control 

efficiency of 90 percent when adding or removing NOx SCR controls at coal-fired plants, 80 

percent when adding or removing NOx SCR controls at gas-fired plants, and 35 percent when 

adding or removing NOx SNCR controls. The specific changes from NCDAQ to the IPM results 

are also summarized in Table 3.1.4-1. 

S/L agencies provided information and/or comment on changes in stack parameters from the 

2002 inventory for the 2009 inventory. Changes to stack parameters were also made in cases 

where new controls are scheduled to be installed. In cases where an emission unit projected to 

have a SO2 scrubber in 2009, some states were able to provide revised stack parameters for some 

units based on design features for the new control system. Other units projected to install 

scrubbers by 2009 are not far enough along in the design process to have specific design details. 

For those units, the VISTAS EGU SIWG made the following assumptions: 1) the scrubber is a 

wet scrubber; 2) keep the current stack height the same; 3) keep the current flow rate the same, 

and 4) change the stack exit temperature to 169 degrees F (this is the virtual temperature derived 

from a wet temperature of 130 degrees F). VISTAS determined that exit temperature (wet) of 

130 degrees F +/- 5 degrees F is representative of different size units and wet scrubber 

technology.

3.2 Non-EGU Emission Projections 

The general approach for assembling future year data was to use recently updated growth and 

control data consistent with the data used in the USEPA’s CAIR analyses, supplement these data 

with available stakeholder input, and provide the results for stakeholder review to ensure 

credibility. The VISTAS/ASIP contractor used the 2002 VISTAS/ASIP base year inventory, 

based on the 2002 CERR submittals as the starting point for the non-EGU projection inventory. 

The 2002 VISTAS/ASIP point source emission inventory contains both EGUs and non-EGUs. 

Since this file contains both EGUs and nonEGU point sources, and EGU emissions are projected 

using the IPM, it was necessary to split the 2002 point source file into two components. The first 

component contains those emission units accounted for in the IPM forecasts. The second 

component contains all other point sources not accounted for in IPM and constitutes the nonEGU emissions inventory. 
Point Source Documentation 17 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

MACTEC performed the following activities to apply growth and control factors to the 2002 

non-EGU emissions inventory to generate the 2009 projection inventory: 

• Obtained, reviewed, and applied the most current growth factors developed by EPA, 

based on forecasts from an updated Regional Economic Models, Inc. (REMI) model 

(version 5.5) and the latest Annual Energy Outlook published by the Department of 

Energy (DOE); 

• Obtained, reviewed, and applied any State-specific or sector-specific growth factors 

submitted by stakeholders; 

• Obtained and incorporated information regarding sources that have shut down after 2002 

and set the emissions to zero in the projection inventories; 

• Obtained, reviewed, and applied control assumptions; 

• Provided data files in NIF3.0 format and emission summaries in EXCEL format for 

review and comment; and 

• Updated the database with corrections or new information from S/L agencies based on 

their review of the 2009 inventory. 

The following sections discuss each of these steps. 

3.2.1 Growth assumptions for non-EGU sources 

The growth factor data used in developing the emission inventory were consistent with the 

USEPA’s analyses for the CAIR rulemaking. These growth factors are fully documented in the 

reports entitled Development of Growth Factors for Future Year Modeling Inventories (dated 

April 30, 2004) and CAIR Emission Inventory Overview (dated July 23, 2004). Three sources of 

data were used in developing the growth factors for the 2009 emissions inventory: 

• State-specific growth rates from the Regional Economic Model, Inc. (REMI) Policy 

Insight® model, version 5.5 (being used in the development of the EGAS Version 5.0). 

The REMI socioeconomic data (output by industry sector, population, farm sector value 

added, and gasoline and oil expenditures) are available by 4-digit SIC code at the 

State level. 
Point Source Documentation 18 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

• Energy consumption data from the DOE’s Energy Information Administration’s (EIA) 

Annual Energy Outlook 2004, with Projections through 2025 for use in generating 

growth factors for non-EGU fuel combustion sources. These data include regional or 

national fuel-use forecast data that were mapped to specific SCCs for the non-EGU fuel 

use sectors (e.g., commercial coal, industrial natural gas). Growth factors for the 

residential natural gas combustion category, for example, are based on residential natural 

gas consumption forecasts that are reported at the Census division level. These Census 

divisions represent a group of States (e.g., the South Atlantic division includes eight 

southeastern States and the District of Columbia). Although one would expect different 

growth rates in each of these States due to unique demographic and socioeconomic 

trends, all States within each division received the same growth rate.

• Specific changes for sectors (e.g., plastics, synthetic rubber, carbon black, cement 

manufacturing, primary metals, fabricated metals, motor vehicles and equipment) where 

the REMI-based rates were unrealistic or highly uncertain. Growth projections for these 

sectors were based on industry group forecasts, Bureau of Labor Statistics (BLS) 

projections and Bureau of Economic Analysis (BEA) historical growth from 1987-2002. 

In addition to the growth data described above, VISTAS received two sets of growth projections 

from stakeholders. The American Forest and Paper Association (AF&PA) supplied growth 

projections for the pulp and paper sector, which were applied to SIC 26xx Paper and Allied 

Products, for growth from 2002 to 2009. The AF&PA projection factor (1.067) is for the United 

States industry and apply to all States equally. The number come from the 15-year forecast for 

world pulp and recovered paper prepared by Resource Information Systems Inc. (RISI). The 

VISTAS/ASIP contractor used the above AF&PA growth factors by SIC instead of the factors 

obtained from the USEPA’s CAIR analysis for the 2009 emission inventory. 

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. For the 2009 inventory, NCDAQ decided to use a growth 

factor of 1.0 for these SIC codes. Although NCDAQ has data that shows a steady decline in 

these industries in North Carolina, NCDAQ wanted to maintain the emission levels at 2002 

levels so the future emission reduction credits were available in the event that they are needed for 

nonattainment areas. 

For the 2009 inventory, the VISTAS/ASIP contractor made one additional change to the growth 

factors. The AEO2004 data was replaced with the more recent AEO2006 forecasts (released in 

February 2006) to reflect changes in the energy market and to improve the emissions growth 
Point Source Documentation 19 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

factors produced. The VISTAS/ASIP contractor obtained the corresponding AEO2006 

projection tables from DOE’s web site. VISTAS developed tables comparing the growth factors 

based on AEO2004 and AEO2006 and these comparison tables were reviewed by the S/L 

agencies. Based on this review, the VISTAS/ASIP states decided to use the AEO2006 growth 

factors for fuel burning SCCs. 

VISTAS used the USEPA’s EGAS model and updated the corresponding AEO2006 projection 

tables to create growth factors by SCC. VISTAS applied the updated growth factors to 2002 

actual emissions and replaced the 2009 emissions in NIF EM tables for the affected SCCs. 

3.2.2 Control Programs applied to non-EGU sources 

VISTAS developed two control scenarios: on-the-books (OTB) controls and on-the-way (OTW) 

controls. The OTB control scenario accounts for post-2002 emission reductions from recently 

promulgated federal, State, local, and site-specific control programs. The OTW control scenario 

accounts for proposed (but not final) control programs that are reasonably anticipated to result in 

post-2002 emission reductions. The methodologies used to account for the emission reductions 

associated with these emission control programs are discussed in the following sections. 

Table 3.2.2-1 Non-EGU Point Source Control Programs Included in 2009 Inventory. 

On-the-Books (Cut-off of July 1, 2004 for Base 1 adoption) 

• Atlanta / Northern Kentucky / Birmingham 1-hr SIPs 

• Industrial Boiler/Process Heater/RICE MACT 

• NOx RACT in 1-hr NAA SIPs 

• NOx SIP Call (Phase I- except where States have adopted II already e.g. NC) 

• RFP 3 percent Plans where in place for one hour plans 

• VOC 2-, 4-, 7-, and 10-year MACT Standards 

• Combustion Turbine MACT 

On-the-Way 

• NOx SIP Call (Phase II – remaining States & IC engines) 

3.2.2.1 OTB - NOx SIP Call (Phase I) 

Phase I of the NOx SIP call applies to certain large non-EGUs, including large industrial boilers 

and turbines, and cement kilns. States in the VISTAS region affected by the NOx SIP call have 

developed rules for the control of NOx emissions that have been approved by the USEPA. 

VISTAS reviewed the available State rules and guidance documents to determine the affected 
Point Source Documentation 20 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

sources and ozone season allowances. VISTAS also obtained and reviewed information in the 

EPA’s CAMD NOx Allowance Tracking System – Allowances Held Report. Since these 

controls are to be in effect by the year 2007, VISTAS capped the emissions for NOx SIP call 

affected sources at 2007 levels and carried forward the capped levels for the 2009 future year 

inventory. 

3.2.2.2 OTB - Industrial Boiler/Process Heater MACT 

The USEPA anticipates reductions in PM and SO2 as a result of the Industrial Boiler/Process 

Heater MACT standard. The methods used to account for these reductions are the same as those 

used for the CAIR analysis. Reductions were included for existing units firing solid fuel (coal, 

wood, waste, biomass), which had a design capacity greater than 10 mmBtu/hr. The USEPA 

prepared a list of SCCs for solid fuel industrial, commercial/ institutional boilers and process 

heaters. The VISTAS/ASIP contractor identified boilers greater than 10 mmBtu/hr using either 

the boiler capacity from the VISTAS 2002 inventory, or if the boiler capacity was missing, a 

default capacity based on a methodology developed by the USEPA for assigning default 

capacities based on SCC code. The applied MACT control efficiencies were 4 percent for SO2 

and 40 for percent for PM10 and PM2.5. 

3.2.2.3 OTB - 2, 4, 7, and 10-year MACT Standards 

Maximum achievable control technology (MACT) requirements were also applied, as 

documented in the report entitled Control Packet Development and Data Sources, dated July 14, 

2004. The point source MACTs and associated emission reductions were designed from Federal 

Register (FR) notices and discussions with the USEPA’s Emission Standards Division (ESD) 

staff. VISTAS did not apply reductions for MACT standards with an initial compliance date of 

2001 or earlier, assuming that the effects of these controls are already accounted for in the 2002 

inventories supplied by the States. Emission reductions were applied only for MACT standards 

with an initial compliance date of 2002 or greater. 

3.2.2.4 OTB Combustion Turbine MACT 

The projection inventory does not include the NOx co-benefit effects of the MACT regulations 

for Gas Turbines or stationary Reciprocating Internal Combustion Engines, which the USEPA 

estimates to be small compared to the overall inventory. 

3.2.2.5 OTW - NOx SIP Call (Phase II) 

The final Phase II NOx SIP call rule was finalized on April 21, 2004. States had until 

April 21, 2005, to submit SIPs meeting the Phase II NOx budget requirements. The Phase II rule 

applies to large IC engines, which are primarily used in pipeline transmission service at 
Point Source Documentation 21 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.1 

North Carolina Attainment Demonstration April 5, 2007 

compressor stations. VISTAS identified affected units using the same methodology as was used 

by the USEPA in the proposed Phase II rule (i.e., a large IC engine is one that emitted, on 

average, more than 1 ton per day during 2002). The final rule reflects a control level of 82 

percent for natural gas-fired IC engines and 90 percent for diesel or dual fuel categories. North 

Carolina provided more specific information on the anticipated controls at the compressor 

stations. This information was used in the 2009 inventory instead of the default approach used 

by the USEPA in the proposed Phase II rule. 

3.2.2.6 Clean Air Interstate Rule 

CAIR does not require or assume additional emission reductions from non-EGU boilers and 

turbines.

Tables 3.2.3-1 and 3.2.3-2 summarize the 2009 non-EGU point source inventory for NOx and

1. INTRODUCTION AND SCOPE 

The attainment modeling for the Charlotte-Gastonia-Rock Hill, NC-SC 8-hour ozone 

nonattainment area (referred to as the Metrolina area) was performed in conjunction with the 

regional haze modeling being done by the Southeast Regional Planning Organization, Visibility 

Improvement State and Tribal Association of the Southeast (VISTAS) and the fine particulate 

matter (PM2.5) and ozone modeling being done by the Association of Southeastern Integrated 

Planning (ASIP). VISTAS and ASIP are run by the ten Southeast states (Alabama, Florida, 

Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West 

Virginia. Since the regional haze and PM2.5 modeling uses annual simulations and includes an 

intermediate year that is the attainment year required for the Metrolina nonattainment area, the 

North Carolina Division of Air Quality (NCDAQ) decided to use the this modeling for its 

attainment demonstration. 

A portion of the emissions inventory was developed by the NCDAQ and the VISTAS/ASIP 

contractors developed a portion. In all cases, a statewide emissions inventory was developed for 

modeling purposes and the emission estimates were calculated in tons per year. Sections 3 

documents the portion of the 2002 base year area source annual emissions inventory that was 

developed by the NCDAQ. Section 4 documents the area source developed by VISTAS/ASIP 

and Section 5 addresses the development of the 2009 area source emissions inventory. Section 6 

and 7 document the nonroad mobile source emissions inventory for 2002 and 2009, respectively. 

A summary of the area source and nonroad mobile source peak ozone season daily emissions, by 

source category, can be found in Appendix E.

2. OVERALL METHODOLOGY 

2.1 SOURCE CATEGORY IDENTIFICATION 

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

(USEPA’s) guidance document EPA-450/4-91-016, Procedures for the Preparation of Emission 

Inventories of Carbon Monoxide and Precursors of Ozone, Vol. 1, from this point on this 

document will be referred to as the Procedures document; the Emissions Inventory Improvement 

Program (EIIP) Technical Reports, Volume 3, Area Sources as of December 2002 (the most 

current version at the time of the inventory development), from this point on this document will 

be referred to as EIIP Tech Report; and a report entitled, Documentation of the Base G 2002 

Base Year, 2009 and 2018, Emission Inventories for VISTAS and written by the VISTAS 

contractor company, MACTEC, Inc. 

Nonroad mobile sources were identified from the USEPA’s 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); and from the USEPA’s nonroad mobile model NONROAD2005c released 

March 21, 2006. 

2.2 AREA SOURCE 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 

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

factors used were obtained from the EIIP Tech Reports, the Procedures document or the 

USEPA’s AP-42 Compilation of Air Pollutant Emission Factors, Fifth Edition, referred to as 

AP-42. 
Area & Nonroad Mobile Sources Documentation 3 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.2 

North Carolina Attainment Demonstration June 15, 2007

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, using population or employment 

data. All of these methods were used to estimate area source emissions 

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 2002 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 

reports were organized by Standard Industrial Classification (SIC) code. 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. The tables from the US Census showing the NAICS-SIC crosswalk 

are reproduced in Section 8 – Additional Data. It should be noted that the crosswalk is based on 

national totals and is not specific to any particular state. In Section 8.2, the employment fraction 

of the NAICS codes used to create the SIC code employment data is tabulated. 

The employment numbers were obtained from the on-line 2002 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 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 
Area & Nonroad Mobile Sources Documentation 4 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.2 

North Carolina Attainment Demonstration June 15, 2007 

4

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 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. 

2.3 NONROAD MOBILE SOURCE EMISSION ESTIMATION APPROACH 

Non-highway mobile sources, sometimes referred to as off-road mobile, are those sources that 

can move but do not use the highway system. Off-road mobile sources are further divided into 

non-road mobile, railroad locomotives, aircraft engines, and commercial marine vessels (CMV). 

The estimation of emissions from mobile sources, like area sources, involves multiplying an 

activity level by an emission factor. 

The majority of the off-road mobile emissions were estimated by using the USEPA’s off-road 

mobile model NONROAD2005c. Direct emissions are generated with this model. For aircraft 

engine emissions, the Federal Aviation Administration (FAA) Emissions and Dispersion 
Area & Nonroad Mobile Sources Documentation 5

North Carolina Attainment Demonstration June 15, 2007 

5

Modeling System (EDMS) model was used. Aircraft operations were inputted into the model 

and the model predicts the engine emissions based on average landing and take-off practices for 

the aircraft type. For railroad locomotive emissions, emission factors were obtained from the 

Mobile Source Procedures document and the activity level was obtained from the various 

railroad companies.

3. NORTH CAROLINA-DEVELOPED 2002 AREA SOURCE 

INVENTORY 

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. 

Emissions are calculated on an annual basis in tons per year. 

3.1 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. 

3.1.1 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, 3) spillage and 4) truck transit losses. The 

emissions from vehicle refueling are captured in the mobile source inventory in the emission 

factors produced by the USEPA’s MOBILE6.2 model and therefore are not estimated as part of 

the area source 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 they meet the quality standards 

of the State. The NCDAQ has worked out an agreement with the Standards Division to also 
Area & Nonroad Mobile Sources Documentation 7

North Carolina Attainment Demonstration June 15, 2007 

7

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 not found to 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 assessed. From this information the rule effectiveness and 

rule penetration can be estimated. The rule effectiveness is the percentage of facilities with 

proper equipment maintenance and use and represents the actual degree of source compliance. 

Rule penetration is the percentage of facilities covered by the rule and thus require Stage I 

equipment. Control efficiency is the expected percent reduction from proper application of this 

control technology. 

The volatile organic compound (VOC) emission factor for underground storage tank filling was 

calculated by using an equation from AP-42, in Section 5.2, Transportation And Marketing Of 

Petroleum Liquids on page 5.2-4 (equation). 

 EF = 12.46 [SPM] x [1-(RE x CE x RP)] 

 [ T ] 

where EF = emission factor in pounds of VOC per 1000 gallons 

 S = Saturation factor 

 P = True vapor pressure (in pounds per square inch area) 

 M = Molecular weight of vapors (lb/lb-mole) 

 T = Temperature of bulk liquid (o Rankin) 

 RE = Rule Effectiveness 

 CE = Control Efficiency 

 RP = Rule Penetration 

The saturation factor was obtained from AP-42, Table 5.2-1 and the true vapor pressure and 

molecular weight of vapors were obtained from AP-42, Table 7.1-2. For the temperature an 

average of the June, July and August average monthly temperature for 2002 was used. A worst 

case temperature estimate was used year round in calculating annual emissions. These 

temperatures were obtained from the North Carolina Climatological Data, a publication of the 

National Oceanic and Atmospheric Administration. All of the factors used to calculate the 

emission factor for Stage I, i.e. balanced submerged filling, are listed in Table 3.1.1-1.

The emission factors for tank truck transit, breathing losses and spillage were obtained from the 

EIIP Tech Report, Chapter 11 Gasoline Marketing, Table 11.3-1 and are listed below in 

Table 3.1.1-2. The tank truck transit emission factor includes the emission rate for an empty 

tank plus a full tank and was adjusted by a factor of 1.25 as recommended by the EIIP Tech 

Report, pg. 11.5-3.

The activity data needed to calculate the emissions is number of gallons of fuel sold in each 

county per year. This was obtained from a report from the North Carolina Petroleum Marketers 

Association. A weighting factor was devised by producing the sum of county population 

(1000’s), county registered vehicles (1000’s), and county motor fuel outlets. The factors were 

summed for the 100 counties and a fractional part of the whole found for each county. This 

fraction was multiplied by the state total gallons of gasoline and diesel sold in 2002 to get an 

estimate of gallons of fuel per county. 

According to the EIIP Tech Report, the activity days per week for truck transit and underground 

storage tank filling are 6 and 7 days per week and for spillage and breathing losses, respectively. 

Note that diesel fuel used is combined with gasoline for the sake of simplification. This will 

result in some overestimation of VOC emissions because the volatility of gasoline is higher than 

diesel fuel. 

Annual VOC emissions for underground storage tank filling, tank truck transit, breathing losses 

and spillage were calculated and SMOKE modeling was later used to allocate annual emissions 

to a daily level. Underground storage tank annual VOC emissions for each county were 

calculated using the following equation. 
Area & Nonroad Mobile Sources Documentation 9

EM = FC x (1/1000) x EF x (1 ton/2000 lbs.) 

where EM = annual county VOC emissions in tons per year 

 FC = county fuel consumption of gasoline and diesel in gallons 

 EF = emission factor in pounds of VOC per 1000 gallons 

Tank truck transit, breathing losses, and spillage annual VOC emissions for each county were 

calculated individually, using the following equation. 

EM = FC x EF x (1 ton/2000 lbs.) 

where EM = annual county VOC emissions in tons per year for tank truck transit, breathing 

 losses, or spillage 

 FC = county fuel consumption of gasoline and diesel in gallons 

 EF = emission factor in pounds of VOC per gallon for tank truck transit, breathing 

 losses, or spillage 

3.1.2 Aircraft Refueling 

Like vehicle refueling, aircraft refueling results in VOC emissions from displacement of the 

vapor laden air in the aircraft’s fuel tank. This source category is generally estimated only for 

large commercial airports. There are a few small commuter and general aviation airports in the 

State; however, the amount of the emissions from these are typically negligible. 

The emissions from aircraft refueling were determined by using the number of gallons of fuel 

supplied to the airports and multiplying it by the appropriate emission factor. The businesses 

that supply the fuel to the airports were contacted to determine the amount and type of fuel 

supplied to each airport during 2002. The information obtained was for the two fuel types 

supplied, Jet A Kerosene and Aviation Gasoline. 

The emission factors used are 11.38 lb VOC/1000 gallons of aviation gasoline and 0.065 lb 

VOC/1000 gallons of Jet A kerosene. Airport refueling occurs on a daily basis, therefore the 

activity days per week are 7. 

The annual emissions for the base year were calculated using equation 3.1.2-1. 

 EMi = Gallons/year x EFi___

where EMi = emissions for source category (i) 

 EFi = emission factor for source category (i) 

 

3.2 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. 

3.2.1 Dry Cleaning 

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

the most part, dry cleaners (coin-operated and conventional commercial) are small business 

entities. As a result of their size, dry cleaning emissions are typically 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 cleaners are estimated by multiplying the number of employees at dry 

cleaners by a national per-employee emission factor, 1800 lbs. of VOC/employee/year, found in 

the EIIP Tech. Report. The guidance also stated that the number of employees can be found in 

the County Business Patterns for SIC code 7215 (coin-operated) and 7216 (commercial). In 

1997, the SIC code system was replaced with the NAICS. Thus, the number of employees was 

obtained for NAICS codes 812310 (coin-operated) and 812320 (commercial). The NAICS 

employment numbers were previously processed to exclude any facilities with 100 or more 

employees, which were deemed to be point sources. According to the SIC to NAICS crosswalk, 

80% of employment for NAICS 812320 represents the number of employees for commercial dry 

cleaners (SIC 7216). 

As reported in the EIIP Tech. Report, the activity days per week is 6 days. The emissions for 

2002 were calculated using equation 3.2.1-1. 

EM = Employees x EF 

 (2000 lb/tons) 3.2.1-1

where EM = emissions for source category tons/year 

 EF = emission factor for source category, 1800 lbs VOC/employee/yr 

3.2.2 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. Therefore, an employee per SIC code 

emission factor is not very reliable. The per-capita emission factor of 1.3 lbs VOC/person/year 

provided by the EIIP Tech. Report was used to calculate the VOC emissions. This emission 

factor estimates the emissions from facilities less than 100 tons VOC/year. It assumes that 

facilities greater than 100 tons VOC/year will be in the point source inventory. The population 

used to calculate the base year emissions was obtained from the North Carolina Office of State 

Budget and Management (OSBM). 

According to the Procedures document, Table 5.8-1, the activity days per week is 5. The annual 

emissions for the base year were calculated using equation 3.2.2-1. 

EM = ((EF)*(Population 2002)*(1 ton/2000 lb)) 3.2.2-1 

where EM = emissions for source category for county (a) ton/yr 

EF = emission factor for source category, 1.3 lbs VOC/person/yr 

3.2.3 Solvent Cleaning and Degreasing 

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 and therefore emit VOC emissions. 
Area & Nonroad Mobile Sources Documentation 12 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.2 

North Carolina Attainment Demonstration June 15, 2007 

12

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. These machines are batch loaded, and 

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 the per employee factors (from the 

EIIP Tech. Report, Chapter 6, Table 6.5-2) listed in Table 3.2.3-1 below:

Employment data was derived from the 2002 County Business Patterns provided by the U. S. 

Census Bureau. For each of these categories, employment in a number of SIC groups is needed. 

These employment numbers were generated from the NAICS employment numbers for each 

county and summed as needed. See SIC Codes from NAICS Codes for Employment Based 

Categories in Section 10 for the full listing of NAICS and SIC for each source category. 

Fractional employee numbers are a result of the NAICS to SIC conversion process.

The annual emissions for the base year were calculated using equation 3.2.3-1. 

EM = (Employment 2002) x EF 

 (2000 lb/tons) 3.2.3-1 

where EM = emissions for source category, tons per year 

EF = emission factor for source category 

3.2.4 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 solvent is typically 100% volatile and can constitute up to 6.5 pounds of VOC 

per gallon of cleaner or paint. 

The EIIP methodology for estimating emissions from this source category recommends 

apportioning a national VOC emission estimate to the county level by the number of employees 

reported for NAISC code 811121. The national estimate of 79,429.59 tons of VOC per year was 

based on 1997 data. In order to estimate the emissions for 2002, the 1997 national VOC estimate 

provided by the EIIP Tech. Report was divided by the 1997 national employment data to create a 

per employee emission factor. 

This emission factor was used with the 2002 employment data to estimate emissions from auto 

body refinishing. The employment data was obtained from the 2002 County Business Patterns. 

According to the EIIP Tech. Report the activity days per week is 5 days. The emissions for 2002 

were calculated using equation 3.2.4-1. 

EM = Employees x EF 3.2.4-1 

where EM = emissions for source category 

 EF = emission factor for source category, 0.387 tons VOC/employee/yr

3.2.5 Architectural Coatings 

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 

data by a usage factor for either water or solvent based coatings, and an emissions factor for 

either water or solvent based coatings. This method entails gathering national architectural paint 

usage from the County Business industrial report MA325F and generating per capita usage 

factors. It is important to be able to differentiate between the water based usage from the solvent 

based usage since the emission factor for solvent based paints is over 5 times higher than the 

factor for water based paints. 

Emissions Factor: Water based = 0.74 lb VOC/gallon; 

Solvent Based= 3.87 lb VOC/gallon 

VOCa = (POPa*UFb*EFb)/(2000lbs/ton) -- ton/year 

Where: VOCa = VOC emissions for county (a) 

 POPa = Population for county (a) 

 EFb = emission factor for paint type (b) 

 UFb = Usage factor for paint type (b) 

The usage factor is found by dividing the national total architectural surface coating quantities 

for either solvent or water-based coatings by the U.S. population for that year. For 2002, the 

usage factor for each paint type is estimated below: 

 UF solvent: (127,703,000 gallons of solvent based) / (287,973,924) = 0.443 gal./person 

 UF water : (589,527,000 gallons of water based) / (287,973,924) = 2.047 gal./person 

3.2.6 Traffic Markings 

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

VOC emissions during the drying process. The extent of emissions is largely a function of the 

paint being solvent or water based. The North Carolina Department of Transportation (NCDOT) 

utilizes three general types of paint, which can be classified as water based paint, epoxy paint 

containing organic solvents, and thermoplastic paint. The use of thermoplastic paint results in 

negligible VOC emissions and therefore is not included in the emissions inventory. 
Area & Nonroad Mobile Sources Documentation 15 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.2 

North Carolina Attainment Demonstration June 15, 2007 

15

Although the NCDOT utilizes both water and solvent based paints, there is uncertainty with 

respect to what percentage of the paint used is organic solvent based. To avoid under estimating 

the emissions from this source category, it is assumed that all paint, excluding thermoplastic, is 

organic solvent based. 

The NCDOT reported that 854,215 gallons of paint were used statewide in 2002. The gallons of 

paint by county were apportioned by number of lane miles in the county divided by the state total 

(equation 3.2.6-1) and the estimated gallons used. The emission factors were obtained from the 

EIIP Tech. Report, Table-14.4-1 and Table-14.5-2, which gave emission factors as a function of 

gallons of paint (3.64 lb VOC/gal.). 

Gallons PaintCounty = (Gallons PaintState) x (# Lane Miles)County 3.2.6-1 

 (# Lane Miles)State

The emissions for 2002 were calculated using equation 3.2.6-2. 

EM = Gallons Paint x EF 3.2.6-2 

 (2000 lb/ton) 

where EM = emissions for source category 

 EF = emission factor for source category 

 

3.2.7 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, three of the 

industrial surface coating subcategories, namely other product coatings, high-performance 

maintenance, and other special purpose coatings, only utilized per capita emission factors and 

have no NAICS associated with them. The emission factors, obtained from the EIIP Tech. 

Report, Table 8.5-2, for these surface coating subcategories are listed in the Table 3.2.7-1 below.

The EIIP Tech. Report also listed SIC codes for these industrial surface coating subcategories. 

As stated earlier, the SIC codes were replaced in 1997 with NAICS. The employment data was 

estimated using the method previously outlined in Subsection 3.2.1. 

According to the EIIP Tech. Report the activity days per week is 5 days. The annual emissions 

for population and employment based emission factors were calculated using equations 3.2.7-1 

and 3.2.7-2, respectively.

3.2.8 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. 

Cutback asphalt emissions are included in the asphalt paving category. Since the assembly of the 

final VISTAS 2002 inventory, it was found that 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 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. Although cutback asphalt emissions are included in the 2002 inventory, the 

93.04 tons of VOC per year represents a relatively small amount and does not significantly affect 

the accuracy of the inventory. 

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 districts and not on a county basis. District 

tonnage was allocated on a county basis by apportioning county paved mileage as reported in the 

NCDOT 2000 Highway Summary Report. However, the amount of emulsified asphalt used is 

not tracked by the NCDOT in any useable way. As a consequence, the NCDOT provided the 

following methodology to predict emulsified usage: 

Square Yd. of hot-mix = (Tons of Hot-mix) x (2000 lbs./Ton) 3.2.8-1 

 (220 lbs/ Square Yd. of Hot-mix) 
Area & Nonroad Mobile Sources Documentation 18

18

Gallons of Emulsified asphalt = (Sq. Yd. of hot-mix) x (0.08 gal./Sq. Yd. of hot-mix) 3.2.8-2 

The VOC emissions were calculated using the emissions factor for emulsified asphalt (9.2 lb 

VOC/barrel) and the number of gallons of emulsified asphalt per barrel (42 gal./barrel) from 

Table 17.5-2 of the EIIP Tech. Report. 

The emissions for the base year were calculated using equation 3.2.8-3. 

EM = (gallons Emulsified Asphalt) x EF 

 (42 gal/barrel) x (2000 lb/tons) 3.2.8-3 

where EM = emissions for source category 

 EF = emission factor for source category 

 

3.2.9 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 amount of asphalt roofing activity is 

estimated by summing the number of felt, cap, and flashing squares used in North Carolina 

during the year 2002. This information was ascertained from the Asphalt Roofing 

Manufacturing Association. The amount of asphalt used is given by the equation 3.2.9-1, which 

uses the default value of 20 lbs. of asphalt / square found in the EIIP Tech. Report. The 

emissions by county, shown in equation 3.2.9-2, were apportioned by roofing establishments in 

the county divided by the state total, using the number of establishments from NAISC code 

23561 from the 2000 County Business Patterns. The 2000 County Business Patterns was the 

latest available data at the time of the inventory development. 

Asphalt (Ton/yr) = (# squares) x (20 lbs. of asphalt/square) 3.2.9-1 

 (2000 lbs./ton) 

AsphaltCounty = (Tons AsphaltState) x (# Roofing Establishments)County 3.2.9-2 

 (# Roofing Establishments)State

Asphalt roofing activities are assumed to have uniform operations throughout the year with a 5-

day work week per the EIIP Tech. Report. Additionally, the EIIP Tech. Report reported the 

emissions factor as 6.2 lbs. VOC/ton asphalt for roofing operations.

3.2.10 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 occur 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 Cooperative Extension office. 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 North Carolina Cooperative Extension office, 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 North Carolina Cooperative Extension office. 

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 reports 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 per year 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 3.2.10-1 and an 

example calculation for soybeans follows. Table 3.2.10-1 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 3.2.10-1

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

Report, p 9.5-4, which relates active ingredients to VOC emissions. According to the EIIP Tech. 

Report, for every pound of active ingredient there are 2.45 pounds of VOC, of this 90% is 

evaporated. The emission factors for each crop were calculated using Equation 3.2.10-2, with an 

example calculation for soybean following. 

 EFCROP = (lb AICROP/acre) x (2.45 lb. VOC/lb. of AI) x (0.90) 3.2.10-2 

Where EFCROP = Emission factor in lbs. VOC/active ingredient for each crop 

 AICROP = Active ingredient for each crop 

For soybeans the emission factor is: 

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

 EFSOYBEAN = (0.844 lb active ingredient/acre) x (2.45 lb VOC/active ingredient) x (0.90) 

 = 1.861 lbs. VOC/acre 

An exception to the above calculation was for the usage of the 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 pounds/acre for 

chloropicrin and 89.5 pounds/acre for 1,3 dichloropropene. Table 3.2.10-2 list the pounds of 

active ingredients per acre and the calculated emission factor for each crop.

3.2.11 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. 

There are seven categories. They are named and their emission factors listed in Table 3.2.11-1 

below.

factors. The county population values are used to estimate the emissions from this source 

category.

3.3 BIOPROCESS EMISSION SOURCES 

Bioprocess emission sources include those sources whose emissions result from biological 

processes (e.g., fermentations). Source categories include bakeries, breweries, wineries and 

distilleries. 

3.3.1 Bakeries 

Ethanol, a VOC, is a by-product of fermentation of bread dough. The ethanol emissions from 

large commercial bakeries are accounted for as point sources; however, ethanol emissions occur 

from grocery store bakery departments and small business bakeries not accounted for under the 

point source inventory. 

The EIIP Tech. Report prescribes accounting for these emissions by the use of a per capita 

consumption factor of 70 pounds of bread per person per year and an emission factor of 0.5 

pounds of VOC per 1000 pounds of baked bread. The county populations obtained from the 

North Carolina Office of State Budget and Management were used to estimate the emissions 

from this source category. 

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

year. The emissions for the base year inventory were calculated using equation 3.3.1-1. 

EM = (Population) b x CF x EF 

 (2000 lb/tons) 3.3.1-1

 Populationb = Population in base year 

 CF = Consumption factor, 70 lb bread/person/year

3.4 OTHER MAN MADE AREA SOURCES 

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

agricultural burning, structure fires, and orchard heaters. The methodology used to calculate the 

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

3.4.1 Structure Fires 

Burning fires can produce short term emissions of organic compounds and nitrogen oxides 

(NOx). The U.S. Fire Administration (USFA) of the Department of Homeland Security 

maintains statistics on the number of fires per county. The number of fires per county for 2002 

was derived from 2001 and 2002 population statistics and 2001 USFA fire statistics. The USFA 

fire statistics were obtained from the USFA website at http://www.usfa.fema.gov/safety/. As 

2002 fire statistics were not available, a fires per person factor for 2001 was calculated and found 

to be equal to 0.00184 fires/person. The 2001 county population values were obtained from the 

North Carolina State Demographics website at http://demog.state.nc.us/. The 2001 population 

values were the latest data available. The 0.00184 fires per person was applied to the 2002 

population for each county to determine the number of fires in each county for 2002. 

The emission factors and fuel loading factors were obtained from the EIIP Tech. Report, 

Table 18.4-1 and Table 18.4-2, respectively. The emission factors are 11 pounds of VOC per ton 

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

burned per structural fire. 

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

year. 

The emissions for the base year 2002 inventory were calculated using Equation 3.4.1-1. 

EMP = (2002 County population) x (FPP) x (CF) x (EFP) 

 (2000 lb/tons) 3.4.1-1 

where EMP = emissions for structure fires for pollutant (P) 

 FPP = fires per person in 2001, 0.00184 fires/person 

 CF = Conversion factor, 1.15 tons burned/structure fire 

 EFP = emission factor for pollutant (P) 

3.4.2 Charbroiling 

The commercial charbroiling of ground beef emits 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 ascertain the number of restaurants in each county in 2002 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. 

According to the EIIP Tech. Report, the average throughput of meat per restaurant with a 

charbroiler is 1160 pounds per week and the emissions factor is 3.94 pounds of VOC per 1000 

pounds of meat. Emissions from this source category occur 365 days per year. 

The emissions for the base year inventory were calculated using Equations 3.4.2-1. 

EMa = (# Restaurants) x (% Charbroiling) x (CF) x (EF)

 (2000 lb/tons) x (1 yr/52 wks) 3.4.2-1 

where EMa = emissions for source category in county (a), tons/yr 

 CF = conversion factor, 1160 lb meat charbroiled/week 

 EF = emission factor, lbs. pollutant/1000 lb meat charbroiled 

3.4.3 Open Burning – Municipal Solid Waste and Yard Trimmings 

This Subsection describes the combined emission inventory methodology for source 

classification code (SCC) 2610030000 Residential Open Burning – Household and SCC 

2610000100 Open Burning – Yard Trimmings. Open burning is treated as a means of waste 

disposal in rural areas. Materials burned generally include agricultural refuse, landscaping 

refuse, or scrap wood. Local authorities could not provide assistance with estimating the tons of 

refuse burned or the amount burned. According to local authorities, burning permits are issued 

year round without requiring a notation for the amount burned. 

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 pounds of MSW is generated per person per 

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

burn within the corporate limits, the rural population was estimated by using the same percentage 

of rural population in each county as what was reported in the 2000 census. The 2000 total and 

rural populations for each county was obtained from the North Carolina Office of State Budget 

and Management, State Data Center. The 2000 total and rural populations was the latest data 

available.

VOC and NOx emission factors for open burning of MSW were obtained from EIIP Tech. 

Report, Table 16.4-1, Open Burning of Municipal Refuse. The emission factors are 6.676 

pounds VOC per ton MSW burned and 6 pounds NOx per ton MSW burned. 

The VOC emission factor for open burning of yard trimmings was obtained from EIIP Chapter 

16, Table 16.4-7. The factor is 28 pounds VOC per ton yard trimmings. The rural percent of the 

populations for the statewide counties were obtained from the 2000 census data. Since burning 

permits are issued year round, the activity days per year was 365. These values were used to 

calculate the tons per year emissions for the base year. The emissions from the burning of MSW 

for the base year 2002 inventory were calculated using equation 3.4.3-1. The emissions from the 

burning of yard trimmings for the base year 2002 inventory were calculated using equation 

3.4.3-2. 

EMP,MSW = (Rural Population in 2002) x (CFMSW) x (EFP) x (365 days/yr)

 (2000 lb/tons) 3.4.3-1 

EMP,YT = (Rural Population in 2002) x (CFYT) x (EFP) x (365 days/yr)

 (2000 lb/tons) 3.4.3-2 

where EMP,MSW = emissions from burning MSW for pollutant (P) 

 EMP,YT = emissions from burning yard trimmings for pollutant (P) 

 CFMSW = conversion factor, 3.77 lb MSW/person/day 

 = 0.001885 ton MSW/person/day 

 CFYT = conversion factor, 0.64 lb yard trimmings/person/day 

 = 0.00032 ton yard trimmings/person/day 

 EFP = emission factor for pollutant (P) 

3.4.4 Small Stationary Source Fossil Fuel Use 

In general, fossil fuels are burned for space and hot water heating. This source category covers 

VOC and NOx emissions from natural gas (NG) and liquid petroleum gas (LPG), oil, coal, and 

wood combustion in the residential, commercial/institutional (called commercial), and industrial 

sectors. 

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

Carolina was taken from NC Energy Outlook 2003 by Global Insight, Inc for the base year 2002. 

The following table shows the data used.

3.4.4.1 Fuel Oil Combustion

Fuel oil consumption covers the use of kerosene, distillate oil and residual oil. Distillate oil 

includes fuel oil grades 1, 2, and 4; residual oil includes fuel grades 5 and 6. In most areas, 

residual oil is not used by residential sources. Kerosene and distillate oils are primarily used for 

space heating in domestic and small commercial buildings, while residual oils are used primarily 

for industrial and large commercial applications. It was assumed that residential fuel oils are 

normally used only for heating and therefore, no residential fuel oil emissions were calculated 

for summer months.

The base year statewide annual fuel oil demand for energy, obtained from the NC Energy 

Outlook 2003, was converted British Thermal Units (BTUs) to gallons of fuel used for each 

heating classification (i.e., residential, commercial, and industrial). The conversion factors used 

were obtained from the NC Energy Outlook 2003 and are 135,000 BTU per gallon of kerosene, 

138,690 BTU per gallon of distillate oil, and 149,690 BTU per gallon of residual oil. 

Once converted to gallons of fuel, the statewide fuel use was then apportioned to the county 

level. This was accomplished by multiplying the number of gallons of fuel used in the state by 

the fraction of housing units heated by fuel oils in the county compared to that of the whole state 

(see the equation below). 

# gal. fuel for County X = (# gal. fuel oil for State) x (# housing units heated by fuel oil in County X)

 (# housing units heated by fuel oil in State)

The fraction of housing units was used to distribute the fuel on a county level for the residential 

heating classifications. The number of housing units heated by fuel oils was obtained from the 

2000 Census. 

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

establishments in the State and counties. The numbers were taken from 1997 (last year of SIC 

based statistics) County Business Patterns. Establishments with SICs from 50xx through 99xx

were summed. Industrial sources were calculated in a manner similar to commercial sources 

burning oil or coal. 

For residential, commercial and industrial consumption, NOx and VOC emission factors were 

obtained from AP-42, Table 1.3-1 and Table 1.3-3, respectively. The residential emission factors 

were 0.018 pounds of NOx per gallon of fuel burned and 0.000713 pounds of VOC per gallon of 

fuel burned. The commercial emission factors were 0.037 pounds of NOx per gallon of fuel 

burned and 0.000735 pounds of VOC per gallon of fuel burned. The commercial emission 

factors were 0.039 pounds of NOx per gallon of fuel burned and 0.00024 pounds of VOC per 

gallon of fuel burned. 

According to the Procedures document, Table 5.8-1, the activity days per week is 7 for 

residential heating and 6 for commercial and industrial heating. These values were used to 

calculate the emissions in tons per year for the base year. 

Point source emissions with SCC 1-03-004-xx and 1-03-005-xx identified commercial residual 

oil and distillate oil emissions, respectively; while source emissions with SCC 1-02-004-xx and 
Area & Nonroad Mobile Sources Documentation 31

North Carolina Attainment Demonstration June 15, 2007 

31

1-02-005-xx identified industrial residual and distillate oil emissions, respectively. The point 

source emissions in tons per year were subtracted from the area source emissions. 

3.4.4.2 Coal Combustion

There are three types of coal used for space heating: anthracite, bituminous and lignite. 

According to AP-42, anthracite, or hard coal, is mined almost exclusively in Pennsylvania and is 

consumed in Pennsylvania and in states that are within easy shipping distance. In addition, 

lignite coal is mined in North Dakota and Texas and is consumed near where it mined. Since the 

incidence of anthracite and lignite coal burning is low in North Carolina, the emissions from coal 

combustion were calculated utilizing only the emission factors for bituminous coal. 

It was assumed that residential coal is normally used only for heating and therefore, no 

residential coal emissions were calculated for summer months. 

The base year statewide annual coal demand for energy, obtained from the NC Energy Outlook 

2003, were converted from BTU to tons of coal used for each heating classification (i.e., 

residential, commercial, and industrial). The conversion factor used was 21,100,000 BTU per 

ton of coal. 

Once converted to tons of coal, the statewide coal use was then apportioned to the county level. 

This was calculated by multiplying the number of tons of coal used in the state by the fraction of 

housing units heated by coal in the county, compared to that of the whole state (see the equation 

below). 

# ton of coal for County X = (# ton of coal for State) x (# housing units heated by coal in County X)

 (# housing units heated by coal in State) 

The fraction of housing units was used to distribute the coal on a county level for both heating 

classifications. The number of housing units heated by coal was obtained from the Federal 

Bureau of the Census and the 2003 NC State Energy Plan 

(http://www.doa.state.nc.us/doa/energy). 

There were several emission factors for bituminous coal combustion listed in AP-42, 

Table 1.1-3. For the purpose of estimating the emissions from coal combustion, the equipment 

listed in AP-42, Table 1.1-3 were grouped into industrial, commercial/institutional and 

residential type equipment. The emission factors were averaged for each type and the averaged 

emission factors were used to calculate the emissions. Table 3.4.4.2-1 lists the averaged 

emission factors used in the calculations. It should be noted that fluidized bed combustors (FBC)

North Carolina Attainment Demonstration June 15, 2007 

32

were not included in the averaged emission factors because FBC does not constitute a significant 

percentage of the total boiler population, according to AP-42, Section 1.1. The Procedures

document, Table 5.8-1, lists the activity days per week as 7 for residential heating and 6 for 

commercial and industrial heating. Point source emissions with SCC 1-03-002-xxidentified 

commercial coal combustion emissions. The point source annual emissions in tons per year were 

subtracted from the area source emissions.

3.4.4.3 Natural Gas Combustion

Currently in the United States, natural gas is one of the major types of fuels used for heating. It 

is mainly used for industrial process stream and heat production, commercial and residential 
Area & Nonroad Mobile Sources Documentation 33

North Carolina Attainment Demonstration June 15, 2007 

33

space heating and for electric power generation. Although natural gas is a relatively clean 

burning fuel, some emissions can result from its combustion. 

The base year statewide annual demand for natural gas energy, obtained from the NC Energy 

Outlook 2003, was converted from BTU to 106 cubic feet of natural gas used for each heating 

classification (i.e., residential, commercial, and industrial). The conversion factor used was 

1,000 BTU per cubic foot of natural gas. 

Once converted to cubic feet of natural gas, the statewide natural gas use was then apportioned to 

the county level. This was calculated by multiplying the number of cubic feet of natural gas used 

in the state by the fraction of housing units heated by natural gas in the county, in comparison to 

the state (see the equation below). 

# ft3 nat gas for County X = (# ft3 nat gas for State) x (# housing units heated by nat gas in County X)

 (# housing units heated by nat gas in State) 

The fraction of housing units was used to distribute the natural gas usage on a county level for 

each heating classification. The number of housing units heated by natural gas was obtained 

from the 2000 Census. 

The North Carolina Utilities Commission provided data from the U.S. Department of Energy, 

Energy Information Administration giving monthly usage of natural gas by residential and 

commercial customers in North Carolina for 2002. 

There were several emission factors listed for industrial and commercial natural gas boilers in 

AP-42, Table 1.4-1. For the purpose of estimating the emissions from natural gas combustion, 

an average of the emission factors were used. Table 3.4.4.3-1 lists averaged emission factors 

used in the calculations. According to the Procedures document, Table 5.8-1, the activity days 

per week is 7 for residential heating and 6 for commercial and industrial heating. These values 

were used to calculate the annual emissions in tons per year for the base year. 

Point source emissions with SCC 1-03-006-xxx and 1-02-006-xxx, identified commercial and 

industrial natural gas combustion emissions, respectively. Where point source emissions were 

indicated, these were deducted from the 2002 annual emission estimates.

3.4.4.4 Liquefied Petroleum Gas Combustion

Liquefied petroleum gas (LPG) consists of propane, propylene, butane, and butylenes. The 

largest market for LPG is the domestic/commercial market, followed by the chemical industry 

and agricultural markets. LPG is also used as a stand-by fuel for facilities that have natural gas 

service contracts that can be interrupted. The form of LPG used primarily for domestic heating 

is propane. Liquefied petroleum gas is considered a clean fuel because it does not produce 

visible emissions. However, gaseous pollutants such as VOC do occur.

35

The base year statewide annual LPG demand for energy, obtained from the NC Energy Outlook 

2003, was converted from BTU to 103 gallons of LPG used for each heating classification (i.e., 

residential, commercial, and industrial). The conversion factor was 95,475 BTU per gallon of 

LPG. 

Once converted to gallons of LPG, the statewide LPG use was then apportioned to the county 

level. This was accomplished by multiplying the number of gallons of LPG used in the state by 

the fraction of housing units heated by LPG in the county compared to that of the whole state 

(see the equation below). 

# gal LPG for County X = (# gal LPG for State) x (# housing units heated by LPG in County X)

 (# housing units heated by LPG in State) 

The fraction of housing units was used to distribute the LPG usage on a county level for each 

heating classification. The number of housing units heated by LPG was obtained from the 2000 

Census. 

The North Carolina Utilities Commission provided data from the U.S. Department of Energy, 

Energy Information Administration giving monthly usage of LPG by residential and commercial 

customers in North Carolina for 2002. 

The emission factors listed in AP-42, Table 1.5-1 were averaged for industrial and commercial 

sources. There is no residential LPG emission factor listed in AP-42. Since the form of LPG 

used primarily for domestic heating is propane, the commercial propane emission factor was 

used for residential LPG combustion. The emission factors listed in AP-42, as well as the 

average emission factors used for estimating the emissions from LPG combustion are listed in 

Table 3.4.4.4-1. According to the Procedures document, Table 5.8-1, the activity days per week 

is 7 for residential heating and 6 for commercial and industrial heating. Point source emissions 

with SCC 1-03-006-xxx and 1-02-006-xxx, identified commercial and industrial natural gas 

combustion emissions, respectively. Where point source emissions were indicated, these were 

deducted from the 2002 annual emission estimate.

3.4.4.5 Wood Combustion

The use of wood as a source of heat occurs in the residential and industrial sectors. It was 

assumed that residential wood is normally used only for heating and therefore, no residential 

wood emissions were calculated for summer months. The burning of wood waste in boilers is 

mostly confined to those industries where the wood is available as a byproduct. Most often this 

is in the lumber, furniture and plywood industries. These types of industries are included in the 

point source inventory, therefore, no area source emissions will be calculated for industrial wood 

combustion. Wood stoves, commonly used in residences as space heaters, are used both as the 

primary source of heat and as a supplement to conventional heating systems. 

The base year statewide annual wood demand for energy, obtained from the NC Energy Outlook 

2003, was converted from BTU to tons of wood used for residential heating. The conversion 

factor was 4,500 BTU per pound of wood, which is the mid-point of the range (4,000 to 5,000 

BTU per pound of wood) given in AP-42, Section 1.6. 

Once converted to tons of wood, the statewide wood use was then apportioned to the county 

level. This was accomplished by multiplying the number of tons of wood use in the state by the 
Area & Nonroad Mobile Sources Documentation 37

fraction of housing units heated by wood in the county compared to that of the whole state (see 

the equation below). 

# tons Wood for County X = (# ton Wood for State) x (# housing units heated by Wood in County X)

 (# housing units heated by Wood in State) 

The fraction of housing units was used to distribute the wood usage on a county level. The 

number of housing units heated by wood was obtained from the 2000 Census. 

Wood combustion emission factors are 229 lb/ton burned and 2.6 lb/ton burned for VOC and 

NOx, respectively. The residential wood combustion emission factors were obtained from the 

Table 2.4-1 of the EIIP Tech. Report, Volume III, Chapter II. According to the Procedures

document, Table 5.8-1, the activity days per week is 7 for residential heating.

3.4.4.6 Small Electric Utility Boilers

This source subcategory has been treated as a point source since the information was available 

for each facility. 

3.4.5 Vehicle Fires 

Vehicle fire emissions within the State demonstration area are estimated by considering the 

estimated number vehicles burned in the State, 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 of the Department of Homeland Security maintains national-level fire 

statistics. The number of fires nationwide in 2002 was 1,734,500 and was available from the 

USFA website at http://www.usfa.fema.gov/statistics/national/. The percentage of vehicle fires 

was applied to the national-level total number of fires. The number of national-level vehicle 

fires was then apportioned to a state-level. The ratio of North Carolina vehicle miles traveled 

(VMT) to U.S. VMT (92,894,000,000 VMT / 2,855,756,000,000 VMT) was applied to the

number of national-level vehicle fires to obtain the number of North Carolina vehicle fires. The 

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

Administration website at http://www.fhwa.dot.gov/policy/ohim/hs02/vm2.htm. The number of 

state-level vehicle fires was then apportioned to a county level based on paved mile per county in 

2002. Paved mile per county data was obtained from the NCDOT. Using the above method, 

2002 vehicle fire emissions were calculated. 

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

assuming that an average vehicle has 500 pounds of components (0.25 tons) that can burn in a 

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

The emission factors were obtained from Table 2.5-1, Emission Factors for Open Burning of 

Municipal Refuse, of the USEPA’s AP-42, Section 2.5 Open Burning. The emission factors are 

32 pounds of VOC per ton burned and 4 pounds of NOx per ton burned. 

The emissions for the base inventory were calculated using equation 3.4.5-1. 

EMP = (# of Vehicle Fires per year) x (CF) x (EFP) 

 (2000 lb/tons) 3.4.5-1 

where EMP = annual emissions for structure fires for pollutant (P) 

 CF = Conversion factor, 0.25 tons burned/vehicle fire 

 EFP = emission factor for pollutant (P) 

3.4.6 Agricultural Burning 

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

These operations include stubble burning, burning of 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, one 

fourth 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 VOC for burning wheat stubble was obtained from

yield of VOC 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 percent of the time. The yield of VOC used, 11 pounds 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 lb VOC/ton burned) 

 = 20.9 lb 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. 

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

Agriculture, Agriculture Statistics Division. The emissions for the 2002 base year inventory 

were calculated using equation 3.4.6-1. 

EM = (1⁄4 x (wheat acreage)) x EF 

 (2000 lb/ton) 3.4.6-1 

where EM = emissions for source category for VOC 

 EF = emission factor for VOC 

3.4.7 On Site Incineration 

On-site incineration is the confined burning of waste leaves, landscape refuse and other refuse or 

rubbish. In North Carolina, commercial/institutional and industrial incinerators are required to 

have an Air Quality Permit in order to operate. Therefore, all industrial incinerators are 

identified in the point source inventory. There may be small commercial/institutional 

incinerators that have not been identified in the point source inventory and as a result emissions 

were calculated for commercial on-site incinerators. 

No data was available to determine the amount of waste burned in on-site incinerators. 

Therefore, the amount of solid waste burned was estimated with the fuel loading factor (L) given 

in Table 4.6-1 of the Procedures document. The commercial fuel loading factor is 23 tons of 

refuse/1,000 population/year. The yield for commercial incineration was obtained from several 

sources. The yield of NOx (P) was obtained from AP-42, Table 2.1-12 and is listed in 

Table 3.4.7-1. The yield value used for NOx was the average of the yield values listed in AP-42.

The yield of VOC is 8.556 lb/ton of refuse and was obtained from EIIP Technical Report, Open 

Burning, Table 16.4-1.

To calculate the per capita pollutant emission factor (EF) for on-site commercial incinerators, the 

fuel loading factor was multiplied by the yield of the pollutant, as shown in the following 

equation. 

 EFP = LCOMMERCIAL x PINCINERATION

 = (23 tons of refuse/1000 population/year) x (2.5 lb NOx/ton of refuse burned) 

 = 57.5 lb NOx/1000 population/year 

The emissions from commercial on-site incineration for the base year 2002 inventory were 

calculated using equation 3.4.7-1. 

EMP = (Rural Population in 2002) x (EFP)

 (2000 lb/tons) 3.4.7-1 

where EMP = emissions from on-site incineration for pollutant (P) in 

 tons/year 

 EFP = emission factor for pollutant (P) 

The population was obtained from the 2000 census data. The 2000 census data was the latest 

data available. According to the Procedures document, on-site incineration occurs uniformly 

year round and operates 7 days per week. Point source emissions with SCC 5-xx-xxx-xx 

identified waste incineration emissions. The point source emissions in tons per year were 

subtracted from the area source emissions.

4. VISTAS DEVELOPED 2002 AREA SOURCE INVENTORY 

Section 4.0 details the portion of the 2002 base year area source inventory, which was developed 

for VISTAS/ASIP by the VISTAS contractor, MACTEC, Inc. This information was obtained 

from the report entitled Documentation of the Base G 2002 Base Year, 2009, and 2018, Emission 

Inventories for VISTAS prepared for VISTAS by MACTEC, Inc. This report is included in 

Appendix Q. 

Several major components of the area source sector of the inventory, which were developed by 

VISTAS, are discussed in Sections 4.1 through 4.3. Stage II emissions are discussed in Section 

4.1 and were removed from the area source inventory and included in the mobile sector of the 

inventory. Also, emissions from portable fuel containers were added and are discussed in 

Section 4.2. Section 4.3 describes the development of the fires emissions inventory and 

distinguishes the difference between an actual versus typical inventory with regards to fires. 

The following Sections are based on excerpts, with some editing, taken from a document 

entitled, Documentation of the Base G 2002 Base Year, 2009 and 2018 Emission Inventories for 

VISTAS and prepared by MACTEC, Inc. 

4.1 Vehicle Refueling (Stage II) emissions 

For the 2002 inventory, the VISTAS/ASIP States all agreed to remove the Stage II refueling 

emissions from the area source inventory and include them in the non-road and on-road sectors. 

4.2 Portable Fuel Containers 

Portable fuel containers (PFCs), SCC 2501060300, covers emissions from residential and 

commercial sector portable gasoline containers. Permeation, diurnal, transport, spillage, and 

vapor displacement emissions are typically accounted for in this category. Spillage from 

refueling operations and vapor displacement emissions were not included in the inventory to 

avoid double counting refueling in the non-road sector. 

MACTEC found that the USEPA had prepared a national inventory of emissions by State for 

portable fuel containers. Data on emissions from this source prepared by the USEPA were 

presented in the report, Estimating Emissions Associated with Portable Fuel Containers (PFCs), 

Draft Report, Office of Transportation and Air Quality, USEPA, Report # EPA420-D-06-003, 

February 2006.

42

The 2002 county-level emission estimates were obtained through an allocation method based on 

fuel usage. Initially, 2005 emission estimates, except those from vapor displacement and 

spillage from refueling operations, were obtained from the USEPA’s report and assumed to be 

equal to 2002 values. Permeation, diurnal, and transport emission estimates were summed and 

allocated to the county-level, based on the fuel usage information obtained from the 

NONROAD2005 model. The SCCs that use containers for refueling were acquired from the 

spillage file of the NONROAD model. Then the fuel usages by county from the NONROAD 

2005 runs prepared for VISTAS/ASIP were summed for those SCCs by county. The county level 

fuel use was then divided by the State total fuel use for the same SCCs to determine the fraction 

of total State fuel usage and that fraction was used to allocate the State-level emissions to the 

county. 

4.3 Forest Fires 

The fires source category includes wildfire, prescribed burning, and land clearing fires. These 

fires can be intermittent in nature, but many of these can produce large quantities of air pollutant 

emissions. Wildfires in certain rural areas can produce large, short-term organic emissions. 

Prescribed burning is used a as a forest management practice to establish favorable seedbeds, 

remove competing underbrush, accelerate nutrient cycling, control tree pests and contribute other 

ecological benefits. Agricultural burning covers agricultural burning practices used to clear 

and/or prepare land for planting. In land clearing fires, waste from logging operations is often 

burned under controlled conditions to reduce the potential fire hazards in forests and to remove 

brush that can serve as a host for destructive insects. 

The total wildfire acreage burned was obtained from the NCDFR for each county in the State. 

These numbers however are replaced with the 2002 “typical” year for the purpose of modeling. 

Fire emissions are not easily grown or projected. Thus, the replacement was done so that the 

fires represented in the area source inventory are considered typical and do not reflect an 

abnormally low or high year as far as fires. The typical year forest fire inventories were 

developed by MACTEC, Inc. with input from state and federal forest resource staff. The typical 

year covered wildfire, prescribed burning, agricultural fires and land clearing fires. The 

development of the typical year inventory is described below. 

State level ratios of acres over a longer-term record (three or more years) developed for each fire 

type relative to 2002. The 2002 acreage was then scaled up or down based on these ratios to 

develop a typical year inventory. VISTAS Fire Special Interest Work Group based the ratio on 

county-level data for States that supplied long-term fire-by-fire acreage data rather than State-
Area & Nonroad Mobile Sources Documentation 43

North Carolina Attainment Demonstration June 15, 2007 

43

level ratios. Where States did not supply long-term fire-by-fire acreage data, MACTEC reverted 

to using State-level ratios. With one broad exception (wildfires) this method was implemented 

for all fires. MACTEC solicited long term fire-by-fire acreage data by fire type from each 

VISTAS State. A minimum of three or more years of data were used to develop the ratios. 

Those data were then used to develop a ratio for each county based on the number of acres 

burned in each county for each fire type relative to 2002. 

If VISTAS had long term county prescribed fire data from a State, a county acreage ratio, 

described below, was developed. 

2002 actual county levelRx acreage

Long term average county levelRx acres Ratio =

This ratio was then multiplied times the actual 2002 acreage to get a typical value (basically the 

long term average county level acres). Wherever possible this calculation was performed on a 

fire-by-fire basis. The acreage calculated using the ratio was then used with the fuel loading and 

emission factor values to calculate emissions. 

There were three exceptions to this method. 

Exception 1: Use of State Ratios for Wildfires

Wildfires estimates were developed using State ratios rather than county ratios because some 

counties were showing unrealistic ratios, which were created by very short term data records or 

missing data. In addition, exceptionally large and small fires were removed from the database. 

VISTAS also removed all fires less than 0.1 acres from the dataset. 

Exception 2: Correction for Blackened Acres on Forest Service Lands

Acres, submitted by the U.S. Forest Service (USFS) for wildfires and prescribed fires on USFS 

lands, represented perimeter acres rather than “blackened” acres. Therefore, for prescribed fires 

greater than 100 acres in size, the acreage was adjusted to be 80 percent of the initial reported 

value. For prescribed fires of 100 acres or less, the acreage values were maintained as reported. 

All reported acreage values for wildfires were adjusted to be 66 percent of their values, as 

initially reported.

Exception 3: Missing/Non-reported data

When VISTAS did not receive data from a VISTAS State for a particular fire type, a composite 

average for the entire VISTAS region was used to determine the typical value for that type fire. 

This technique was applied to all fire types when data was missing. 

For wildfires and prescribed burning, ratios were also developed for “northern” and “southern” 

tier States within the VISTAS region and those ratios were applied to each State with missing 

data depending upon whether they were considered a “northern” or “southern” tier State. 

Development of “southern” and “northern” tier data was an attempt to account for a change from 

a predominantly pine/evergreen ecosystem (southern) to a pine/deciduous ecosystem (northern). 

Table 4.3-1 below presents a comparison in tons per year of the 2002 actual fire emissions and 

the 2002 typical fire emissions for NOx and VOC for wildfires, prescribed burning, agricultural 

fires and land clearing fires in North Carolina.

5. 2009 AREA SOURCE EMISSION INVENTORY DEVELOPMENT 

This Section describes the methodology used to develop the 2009 area source inventory. 

Separate methods for projecting emissions were used for non-agricultural (stationary area), 

agricultural area sources and forest fire area sources. The agricultural area sources method are 

for ammonia emissions and are not related to ozone formation, therefore it will not be discussed 

in this documentation. Since ammonia is important for regional haze and fine particulate matter, 

the method for projecting agricultural area sources will be detailed in the respective State 

Implementation Plans. 

The following Sections are based on excerpts, with some editing, taken from a document 

entitled, Documentation of the Base G 2002 Base Year, 2009 and 2018 Emission Inventories for 

VISTAS and prepared by MACTEC, Inc. 

 5.1 Projection of Stationary Area Sources 

VISTAS 2002 base year inventory emissions were used as a starting point for calculating 2009 

emissions. MACTEC, Inc. first back calculated uncontrolled emissions from the 2002 base year 

inventory. Growth and control factors were then applied based on controls initially identified for 

the Clean Air Interstate Rule (CAIR) and growth factors identified for the CAIR projections. In 

some cases, Economic Growth Analysis System version 5.0 (EGAS 5.0) growth factors were 

used if no growth factor was available from the CAIR growth factor files. 

The 2009 growth factors were obtained from the USEPA growth factors and indirectly from 

2010 and 2015 CAIR growth factors. Using a 2001 base year, interpolation of 2010 and 2015 

CAIR growth factors yielded 2009 growth factors. MACTEC used the TREND function of 

Microsoft Excel for interpolation. Interpolated growth factors were calculated at the State and 

SCC level. 

In a few cases, additional growth factors had to be added for sources that had not initially been 

included in a draft 2002 inventory. These growth factors were obtained from EGAS 5.0. Finally 

updates to growth factors from EGAS 5.0 were made for fuel fired emission sources. The 

updated growth factors reflected the most recent data from the Department of Energy’s Annual 

Energy Outlook (AEO). These data were used to reflect changes in energy efficiency resulting 

from new or updated fuel firing technologies. 
Area & Nonroad Mobile Sources Documentation 46

46

North Carolina provided 2009 updated emission files used to update the emissions for each year 

for several source categories. However not all sources in the inventory were included in these 

North Carolina updates. As a consequence, the final 2009 inventory for North Carolina included 

emissions updated using the North Carolina supplied files and emissions developed using growth 

and control factors as outlined above. 

5.2 Projection of Forest Fires Area Sources 

Several Federal agencies indicated that they had plans for increased prescribed fire burning in 

future years and that the “typical” fire inventory would likely not adequately capture those 

increases. Thus, MACTEC acquired the data necessary to provide 2009 specific projections for 

the prescribed fire component of the fire inventory. 

The U.S. Fish and Wildlife Service (USFWS) submitted annual acreage data by National 

Wildlife Refuge (NWR) and by county with estimates of acres burned per day for each NWR. 

USFS provided fire-by-fire acreage estimates based on mapping projected burning acreage to 

current 2002 modeling days. However, USFWS did not submit data for VISTAS original base 

year preparation process, thus there was no known USFWS data in the 2002 actual or typical 

inventories. MACTEC therefore developed a method that could use the county-level data 

submitted by USFWS. 

Several VISTAS/ASIP States run a prescribed fire-permitting program. To avoid double 

counting, only State data and not USFWS or USFS data was used in those States for the 2002 

actual inventory. 

The method used by MACTEC to include the USFS data applied a county level data approach 

for USFS data where a State had a prescribed fire permitting program and a fire-by-fire 

replacement for USFS data in States without permit programs. MACTEC used a county level 

approach for all of the USFWS data. The approach used for each data set is discussed below. 

For USFWS data, 2002 annual county acres burned was subtracted from the USFWS projected 

acreage. A 0.8 factor was applied to the difference to account for blackened acres instead of the 

total perimeter acres that were reported. The revised total additional USFWS acreage was then 

added to the total county “typical” acreage to determine future acreage burned for 2009. 

MACTEC then allocated the increased acreage to current modeling days. The average daily acres 

burned data provided by USFWS per NWR/county was used to allocate the acreage to the 
Area & Nonroad Mobile Sources Documentation 47 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.2 

North Carolina Attainment Demonstration June 15, 2007 

47

correct number of days required to burn all of the acres. Guidance supplied by USFWS indicated 

that up to three times the average daily acres burned could potentially be allocated to any one 

day. 

For the USFS fire-by-fire acreage estimates, MACTEC summed the USFS data at a county-level 

for States that had permit programs, then added the sum to the typical acreage and allocated the 

acres to current modeling days. For States that do not have a State prescribed fire permit 

program, MACTEC simply replaced the current fire-by-fire records in the database with fire-byfire records from the USFS and recalculated emissions based on fuel model and fuel loading. 

VISTAS also applied the same 0.8 correction for blackened acres applied to all USFS supplied 

acreage as the supplied values represented perimeter acres. 

An additional problem with developing year-specific prescribed fire projections was how to 

adequately capture the temporal profile for those fires. In the 2002 actual fire inventory, fires 

occur on same days as state/FLM records. In the 2002 “typical” year inventory, fire acreage 

increased or decreased from acreage on the same fire days as were in the 2002 actual inventory, 

since the acres were simply increased for each day based on a multiplier used to convert from 

actual to typical. 

When prescribed fires acreage was added to a future year, MACTEC added acreage to individual 

fire days proportional to the annual increase (if acreage on a day is 10 percent of annual, add 10 

percent of projected increase to that same day).

6. VISTAS DEVELOPED 2002 NONROAD MOBILE SOURCE 

INVENTORY 

Development of emission estimates for nonroad mobile sources is documented in the MACTEC, 

Inc. document titled Documentation of the Base G 2002 Base Year, 2009 and 2018, Emission 

Inventories for VISTAS. 

Nonroad mobile sources are those sources that can move but do not use the highway system. 

Examples include lawn mowers, agricultural equipment, construction equipment, aircraft 

engines, railroad locomotives, powerboats, and commercial marine (ships). All but the aircraft 

engine, railroad locomotive emissions and commercial marine activity were estimated using the 

USEPA’s off-road mobile model NONROAD2005c, which was released March 21, 2006. 

Direct emissions are generated with this model. This version incorporates all the USEPA final 

nonroad mobile engine emission standards, including the recreational and large spark-ignition 

engines rules that were published in the Federal Register in November 2002. Although this 

model is considered to be a final model, an updated version is planned that may incorporate 

revised inputs for the small spark-ignition (SI) (<19 kW) and recreational marine SI categories in 

conjunction with additional promulgated nonroad mobile engine standards. 

Nonroad mobile sources calculated through the NONROAD model are discussed in Section 6.1 

Aircraft, railroad and commercial marine emissions are discussed in Sections 6.2 through 6.4. 

6.1 NONROAD Model Sources 

The nonroad mobile source category includes a diverse collection of equipment such as lawn 

mowers, chain saws, tractors, all terrain vehicles, fork lifts and construction equipment. The 

USEPA NONROAD2005c model generates emissions directly and includes more than 80 

different types of equipment. To facilitate analysis and reporting, the USEPA grouped the 

equipment types into ten equipment categories. These include: 

Agricultural equipment Lawn and garden equipment 

Airport ground support equipment Logging equipment 

Commercial equipment Railroad maintenance equipment 

Construction equipment Recreational marine equipment 

Industrial equipment Recreational equipment 
Area & Nonroad Mobile Sources Documentation 49 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.2 

North Carolina Attainment Demonstration June 15, 2007 

49

Additionally, the emissions are broken out by five different engine types. These include: 

2-stroke and 4-stroke spark engines, diesel engines, liquid petroleum gas (LPG) and compressed 

natural gas (CNG) fueled engines. 

One of the default input files was edited to reflect North Carolina specific information. In the 

“SEASON.DAT” file, the region representative of North Carolina was changed from MidAtlantic to Southeast. This was done after an evaluation of the meteorological data in the two 

files and comparing it to that of Charlotte. Default data was used for the remaining input files 

used in the NONROAD model. 

6.2 Aircraft Engines 

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 has little or no effect on ground 

level ozone. 

The aircraft operations of interest are termed 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 climbout as it heads back to cruising altitudes, above the 

mixing layer. 

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 and/or freight. Air taxis, or 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. General aviation include 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. The military aircraft are treated as a separate classification 

since the LTO operations reported at the airports group all military aircraft together. 

Emission factors are available for the many aircraft and engine combinations that exist. Factors 

for each aircraft exist for four operating modes in the LTO cycle. Emissions are calculated by 

obtaining data for the number of LTO cycles of the various aircraft at each airport in question, 

multiplying by the appropriate factors, and summing the results for the year under consideration.

Development of the 2002 aircraft emissions are described in the MACTEC document titled 

Documentation of the Base G 2002 Base Year, 2009 and 2018 Emission Inventories for VISTAS . 

This document refers back to a document titled “Development of the VISTAS Draft 2002 Mobile 

Source Emission Inventory (February 2004 Version)” prepared by E.H. Pechan & Associates, 

Inc. Both of these documents are included in Appendix Q. 

The starting point for development of aircraft emissions estimates is the 1999 National Emission 

Inventory (1999 NEI) prepared by the USEPA. These emissions were grown to appropriate 

values for 2002 and 2009 using growth factors developed by the USEPA for the CAIR. Along 

the way there was input by the various States including North Carolina to arrive at more accurate 

emission estimates. 

6.3 Railroad Locomotives 

Railroads are categorized by size (Class I, Class 2) and passenger service (Amtrak and North 

Carolina Department of Transportation (NCDOT) Rail Division). Class I railroads are long haul 

operations, consisting of Norfolk Southern Corporation and CSX Corporation in North Carolina. 

Class II and Class III railroads are short lines, serving localized markets. Passenger service is 

provided by Amtrak and the NCDOT Rail Division in North Carolina. These entities lease 

trackage from Class I railroads. 

Development of railroad emissions is described in the MACTEC document titled Documentation 

of the Base G 2002 Base Year, 2009 and 2018 Emission Inventories for VISTAS. The 

VISTAS/ASIP railroad emission estimates started with 1999 emission estimates developed for 

the USEPA’s 1999 NEI Version 2 as base year estimates for the VISTAS region. Additional 

information is provided in “Development of the VISTAS Draft 2002 Mobile Source Emission 

Inventory (February 2004 Version)” prepared by E.H. Pechan & Associates, Inc. 

Projected emissions for 2002 were developed in two steps as described below. For 1999 to 2001, 

State-level rail fuel consumption was obtained from the Department of Energy, Energy 

Information Administration’s (EIA’s) Fuel Oil and Kerosene Sales. For 2001 to 2002, VISTAS 

applied national growth factors developed from fuel consumption projections in EIA’s Annual 

Energy Outlook. A growth factor of 1.4 was used for locomotives and applied to 1999 emissions 

to first develop 2001 emissions. Table 6.3-1 lists the growth factors used to generate 2002 

emissions.

6.4 Commercial Marine Vessel (CMV) 

The following description of development of commercial marine emission estimates is based on 

excerpts, with some editing, taken from the MACTEC document titled Documentation of the 

Base G 2002 Base Year, 2009 and 2018 Emission Inventories for VISTAS and a document titled 

“Development of the VISTAS Draft 2002 Mobile Source Emission Inventory (February 2004 

Version)” prepared by E.H. Pechan & Associates, Inc 

An initial 2002 base year emissions inventory for commercial marine vessels (CMV) was 

prepared for VISTAS in early 2004. The methods and data used to develop the inventory are 

presented in a February 9, 2004 report “Development of the VISTAS Draft 2002 Mobile Source 

Emission Inventory (February 2004 Version)” prepared by E.H. Pechan & Associates, Inc. 

Revisions to the initial 2002 emissions inventory (prepared by Pechan) were implemented to 

ensure that the latest State and local data were incorporated. For CMV, North Carolina provided 

no revised data.

For 2002 commercial marine vessels (CMVs), Pechan used 1999 emission estimates developed 

for the USEPA’s 1999 NEI Version 2 as base year estimates for the VISTAS region. Pechan 

then improved the spatial distribution of CMV emission estimates for the VISTAS region. 

Ideally, CMV emission estimates would be developed using local activity data that account for 

vessel type, engine type and mode of operation (cruise, maneuvering, and hotelling). Creating 

this type of “bottom-up” emission inventory requires a large amount of effort. Therefore, Pechan 

utilized port-specific emission estimates developed for the 1999 NEI, distributed using a revised 

allocation methodology, which incorporates information on the number of port facilities in each 

county. 

The 2002 VISTAS commercial marine inventory is based on the USEPA’s 1999 NEI Version 

2.0, projected to 2002 using appropriate growth factors. The 1999 NEI estimated emissions for 

these categories according to the following SCCs: 

SCC Descriptor 1 Descriptor 3 Descriptor 6 Descriptor 8 

2280002100 Mobile Sources Marine Vessels, Commercial Diesel Port emissions 

2280002200 Mobile Sources Marine Vessels, Commercial Diesel Underway emissions 

2280003100 Mobile Sources Marine Vessels, Commercial Residual Port emissions 

2280003200 Mobile Sources Marine Vessels, Commercial Residual Underway emissions 

For the 1999 NEI, commercial marine diesel emissions were developed by obtaining 2000 

emission estimates for all pollutants except SO2 from the USEPA’s Office of Transportation and 

Air Quality (OTAQ) marine diesel regulatory background documentation (Draft Regulatory 

Impact Analysis - Control of Emissions from Compression-Ignition Marine Engines). To 

estimate emissions for 1999, 2000 estimates were backcast using growth factors obtained from 

the draft Regulatory Impact Analysis (RIA) cited above. Steam-powered residual CMV 

emission estimates were developed by obtaining fuel usage data from OTAQ and applying fuelbased emission factors. A similar method was used for diesel SO2 emissions. National diesel 

usage was estimated assuming a sulfur content of 0.25 percent and USEPA emission factors. 

In apportioning, distillate and residual fuels are considered separately. National diesel emissions 

were disaggregated into port and underway emissions estimates based on the assumption that 75 

percent of distillate fuel is consumed within the port, while the remaining fuel is consumed while 

underway, consistent with USEPA guidance. National residual emissions were disaggregated 

into port and underway emissions estimates based on the assumption that 25 percent of residual 

fuel is consumed within the port, while the remaining fuel is consumed while underway.

To allocate to counties, port emissions were assigned to the 150 largest U.S. ports based on 

activity obtained from the U.S. Army Corps of Engineers (USACE). The percentage of total 

traffic for each port was calculated by dividing the port-level traffic by the total traffic. 

Emissions for each port were then assigned to a single county. 

Underway emissions are assigned to counties based on a county’s shipping lane traffic. The 

Bureau of Transportation Statistics’ (BTS) National Transportation Atlas Databases-1999 

contains data on the thousand tons per mile traveled for each shipping lane link in the United 

States (BTS-CD26). Where navigable rivers form a county or State boundary, the shipping lane 

traffic is proportioned to individual counties based on the length of shoreline that is shared. For 

example, if two counties share a navigable river, and both counties have the same length of 

shoreline, the shipping traffic is split evenly between the two counties. Shipping lanes that are 

not within counties, for example in the ocean, are associated to States based on BTS 

assignments. These waterway weights are then evenly distributed among the counties within 

these States that have navigable waterways. All shipping activity is summed at the county-level 

and compared with national shipping activity to determine what portion of activity can be 

attributed to individual counties. These proportions were used in disaggregating the national 

CMV emission estimates to the county level. 

States that share borders with non-VISTAS States along the Mississippi and Ohio Rivers have 

expressed concern about the representativeness of port emission estimates at a county-level. 

Revising the county-level emissions estimates would allow more accurate modeling of emissions 

in the VISTAS states. 

For underway emissions, Pechan believes that the allocation procedure results in a reasonable 

distribution of county-level emissions. However, the methodology to allocate port emissions 

results in all the emissions being assigned to a single county. 

Port areas encompass multiple States and counties and in some cases, multiple waterways. 

Therefore, the emissions allocation process must incorporate all counties in the vicinity of the 

port where activity is occurring. This is especially true for inland rivers where activity takes 

place on both riverbanks and for ten river miles or more outside the port city. The revised 

methodology allocates port emissions based on a surrogate for port-related activity in each 

county, rather than using a single county to define the port. 

The report, Waterborne Commerce of the United States, Calendar Year 1999, hereafter referred 

to as Waterborne Commerce, presents the cargo tonnage and number of vessel trips in major 

waterways of the United States. The report defines port areas, which USACE uses to develop 
Area & Nonroad Mobile Sources Documentation 54

54

the Top 150 Ports in the United States by amount of cargo tonnage. As discussed previously, the 

1999 NEI allocates all the port emissions to these 150 ports based on the cargo tonnage handled 

by the port. Pechan uses this allocation of emissions to each port area as the starting point of its 

revised allocation process. Morehead City Harbor and the Port of Wilmington are the two main 

ports in North Carolina. 

The next step was to develop a list of counties that make up the port area. Port area definitions 

were obtained from Waterborne Commerce. The port area definition for Morehead City Harbor 

port was “Morehead City Harbor, NC”. The port area definition for Wilmington City port was 

“Both banks of the Cape Fear River extending from a point about 18 miles below the foot of 

Castle St. in Wilmington to a point about 2 miles above the Railroad Bridge at Navassa, and both 

banks of Northeast (Cape Fear) River from its mouth to a point about 1.67 miles above the 

Hilton Railroad Bridge”. Using the port definitions by river mile, Pechan established which 

counties are included in each port area. The Port of Wilmington is included in the counties of 

Hanover and New Brunswick. The Morehead City Harbor is included in Carteret county. 

The next step in allocating emissions is to develop a surrogate for the amount of CMV activity in 

each county of the port area. Pechan assumed that the activity of vessels in each county is 

related to the number of port facilities operating in a given county. Port facilities include 

terminals, piers, wharves, and docks that are involved in all types of commercial activity and 

support services. Pechan obtained the number of port facilities in each county from USACE 

reports, The Port Series Reports. The USACE periodically surveys the commercial marine 

industry to obtain information on port facilities and publishes it in The Port Series Reports. The 

reports give the name, location, operations, and describe the physical and inter-modal 

characteristics of the facilities. The data includes the location of the facility by river mile, State, 

and county. 

For each port area, Pechan calculated the ratio between the number of port facilities in each 

county to the total number of facilities in all counties that make up the port area. This ratio was 

used to allocate emissions for each port area to the county-level. The ratio for Morehead City 

Harbor was 1.0 in Carteret county and the ratios for the Port of Wilmington were 0.8974 in New 

Hanover county and 0.1026 in Brunswick county. Pechan was directed to perform the 

reallocation for all VISTAS ports.

7. 2009 NONROAD MOBILE SOURCE EMISSION INVENTORY 

DEVELOPMENT 

The subsections that follow describe the projection process used to develop 2009 nonroad mobile 

source projection estimates for sources found in the NONROAD model and those sources 

estimated outside of the model (locomotives, airplanes, and commercial marine vessels). 

7.1 Projection of NONROAD Model Sources 

NONROAD model input files were prepared based on the 2002 base year inventory input files 

with appropriate updates for the projection years. Other specific updates for the projection years 

for NONROAD model sources consist of: 

1. Revise the emission inventory year in the model (as well as various output file naming 

commands) to be reflective of the projection year. 

2. Revise the fuel sulfur content for gasoline and diesel powered equipment. 

3. Implement a limited number of local control program changes (national control 

program changes are handled internally within the NONROAD model, so explicit input 

file changes are not required). 

All equipment population growth and fleet turnover impacts are handled internally within the 

NONROAD model, so that explicit input file changes are not required. 

The final NONROAD2005c that was used for inventory development is capable of handling 

separate diesel fuel sulfur inputs for land-based and marine-based nonroad mobile source 

equipment in a single model execution. The following diesel fuel sulfur values were used: 

 Diesel S (ppm) 2002 2009 

 Land-Based 2500 348 

 Marine-Based 2638 408 

7.2 Projection of Non-NONROAD Model Sources 

Using the 2002 base year emissions inventory for aircraft, locomotives, and CMV prepared as 

described earlier in this document, corresponding emission projections for 2009 were developed. 

The following description is largely taken from the MACTEC document titled Documentation of 
Area & Nonroad Mobile Sources Documentation 56

North Carolina Attainment Demonstration June 15, 2007

the Base G 2002 Base Year, 2009 and 2018 Emission Inventories for VISTAS. Briefly, the 

methodology relies on growth and control factors developed from inventories used in support of 

recent USEPA rulemakings, and consists of the following steps: 

(a) Begin with the 2002 base year emission estimates for aircraft, locomotive, and CMV. 

(b) Detailed inventory data (both before and after controls) for these same emission sources 

for 1996, 2010, 2015, and 2020 were obtained from the USEPA's CAIR Technical 

Support Document. Using these data, combined growth and control factors for the period 

2002-2009 were estimated using straight line interpolation between 1996 and 2010 (for 

2009). This is done at the State-county-SCC-pollutant level of detail. 

(c) The USEPA growth and control data are matched against the 2002 VISTAS base year 

data using State-county-SCC-pollutant as the match key. Ideally, there would be a 

one-to-one match and the process would end at this point. Unfortunately, actual match 

results were not always ideal, so additional matching criteria were required. For 

subsequent reference, this initial (highest resolution) matching criterion is denoted as the 

“CAIR-Primary” criterion. 

(d) A second matching criterion is applied that utilizes a similar, but higher-level SCC (lower 

resolution) matching approach. For example, SCC 2275020000 (commercial aircraft) in 

the 2002 base year inventory data would be matched with SCC 2275000000 (all aircraft) 

in the CAIR data. This criterion is applied to records in the 2002 base year emissions file 

that are not matched using the “CAIR-Primary” criterion, and is also performed at the 

State-county-SCC-pollutant level of detail. For subsequent reference, this is denoted as 

the “CAIR-Secondary” criterion. At the end of this process, a number of unmatched 

records continued to remain, so a third level matching criterion was required. 

(e) In the third matching step, the most frequently used SCC in the USEPA CAIR files for 

each of the aircraft, locomotive, and commercial marine sectors is averaged at the State 

level to produce a “default” State and pollutant-specific growth and control factor for the 

sector. The resulting factor is used as a “default” growth factor for all unmatched 

county-SCC-pollutant level data in each State. In effect, State-specific growth data are 

applied to county level data for which an explicit match between the VISTAS 2002 base 

year data and the USEPA CAIR data could not be developed. The default growth and 

control SCCs are 2275020000 (commercial aircraft) for the aircraft sector, 2280002000 

(commercial marine diesel total) for the CMV sector, and 2285002000 (railroad

57

equipment diesel total) for the locomotive sector. Matches made using this criterion are 

denoted as “CAIR-Tertiary” matches. 

(f) According to USEPA documentation, the CAIR baseline emissions include the impacts 

of the (then proposed) Tier 4 (T4) nonroad mobile diesel rulemaking, which implements 

a low sulfur fuel requirement that affects both future CMV and locomotive emissions. 

However, the impacts of this rule were originally intended to be excluded from the initial 

VISTAS 2018 forecast, which was to include only “on-the-books” controls. (The T4 rule 

was finalized subsequent to the development of the preliminary 2018 inventory in March 

of 2004.) Given its final status, T4 impacts have now been moved into the “on the 

books” inventory for nonroad mobile source equipment. In addition, since there are no 

other proposed rules affecting the nonroad mobile source sector between 2002 and 2018, 

there is no difference between the 2018 “on the books” and 2018 “on the way” 

inventories for the sector; so that only a single forecast inventory (for each evaluation 

year) was developed. Nevertheless, since the algorithms developed to produce the 

VISTAS forecasts were developed when there was a distinction between the “on the 

books” and “on the way” inventories, the distinct algorithms used to produce the two 

inventories have been maintained even though the conceptual distinctions have been lost. 

This approach was taken for two reasons. First, it allowed the previously developed 

algorithms to be utilized without change. Second, it allowed for separate treatment of the 

T4 emissions impact which was important as those impacts have changed between the 

proposed and final T4 rules. Thus, previous USEPA inventories that include the proposed 

T4 impacts would not be accurate. Therefore, the procedural discussion continues to 

reflect the distinctions between non-T4 and T4 emissions, as these distinctions continue 

to be intrinsically important to the forecasting process. Therefore, a second set of USEPA 

CAIR files that excluded the Tier 4 diesel impacts was obtained and the same matching 

exercise described above in steps (b) through (e) was performed using these “No T4” 

files. It is important to note that the matching exercise described in steps (b) through (e) 

cannot simply be replaced because the “No T4” files obtained from the USEPA include 

only those SCCs specifically affected by the T4 rule (i.e., diesel CMV and locomotives). 

So in effect, the matching exercise was augmented (rather than replaced) with an 

additional three criteria analogous to those described in steps (c) through (e), and these 

are denoted as the “No T4-Primary,” “No T4-Secondary,” and “No T4-Tertiary” criteria. 

Because they exclude the impacts of the proposed T4 rule, matches using the “No T4” 

criteria supersede matches made using the basic CAIR criteria (as described in steps (c) 

through (e) above).

(g) The CAIR matching criteria were overridden for any record for which States provided 

local growth data. Only North Carolina provided these forecasts, as North Carolina has 

provided specific growth factors for airport emissions in four counties. Because the 

provided data were based on forecasted changes in landings and takeoffs at major North 

Carolina airports, the factors were applied only to commercial (SCC 2275020000) and air 

taxi (SCC 2275060000) emissions. Emissions forecasts for military and general aviation 

aircraft operations, as well as all aircraft operations in counties other than the four 

identified in the North Carolina growth factor submission, continued to utilize the growth 

factors developed according to steps (b) through (f) above. The locally generated growth 

factor (2002 to 2009) applied in Mecklenburg County was 1.15. 

(h) Using this approach, each State-county-SCC-pollutant was assigned a combined growth 

and control factor using the USEPA CAIR forecast or locally provided data. The 22,838 

data records for aircraft, locomotives, and CMV in the 2002 base year emissions file were 

assigned growth factors in accordance with the following breakdown: 

 48 records matched State-provided growth factors, 

 4,179 records matched using the CAIR-Primary criterion, 

 240 records matched using the CAIR-Secondary criterion, 

 7,463 records matched using the CAIR-Tertiary criterion, 

 720 records matched using the No T4-Primary criterion, 

 3,858 records matched using the No T4-Secondary criterion, and 

 6,330 records matched using the No T4-Tertiary criterion. 

(i) Finally, the impacts of the T4 rule as adopted were applied to the grown “non T4” 

emission estimates. The actual T4 emission standards do not affect aircraft, locomotive, 

or CMV directly, but associated diesel fuel sulfur requirements do affect locomotives and 

CMV. Lower fuel sulfur content affects both SO2 and PM emissions. Expected fuel 

sulfur content was obtained for 2009 from the USEPA technical support document for the 

final T4 rule (Final Regulatory Analysis: Control of Emissions from Nonroad Diesel 

Engines, EPA420-R-04-007, May 2004). According to that document, the average diesel 

fuel sulfur content for locomotives and CMV is expected to be 408 parts per million by 

weight (ppmW) in 2009. This compares to expected non-T4 fuel sulfur levels of 

2599 ppmW in 2009. Table 7.2-1 uses calculated emissions estimates for base and T4 

control scenarios to estimate emission reduction impacts.

Table 7.2-1 Estimated Emission Reduction Impacts based on T-4 Rule 

2009

CMV SO2 = Non-T4 SO2 × 0.1569

Locomotive SO2 = Non-T4 SO2 × 0.1569 

CMV PM = Non-T4 PM × 0.8962 

Locomotive PM = Non-T4 PM × 0.8117 

However, since the diesel fuel sulfur content assumed for the 2002 VISTAS base year 

inventory, upon which the 2009 inventory was based, is 2500 ppmW, a small adjustment 

to the emission reduction multiplier calculated from the T4 rule is appropriate since they 

are measured relative to modestly different sulfur contents (2599 ppmW for 2009). 

Correcting for these modest differences produces the emission reduction impact estimates 

relative to forecasts based on the VISTAS 2002 inventory shown in Table 7.2-2. 

Table 7.2-2 Estimated Emission Reduction Impacts Relative to VISTAS 2002 Base 

Year Values 

2009

CMV SO2 = Non-T4 SO2 × 0.1632 

Locomotive SO2 = Non-T4 SO2 × 0.1632 

CMV PM = Non-T4 PM × 0.9004 

Locomotive PM = Non-T4 PM × 0.8187 

These factors were applied directly to the non-T4 emission forecasts to produce the final 

VISTAS 2009 emissions inventories for aircraft, locomotive, and CMV. 

During the development of the preliminary 2018 VISTAS inventory in March 2004, this process 

yielded reasonable results and exhibited no particular systematic concerns. However, when the 

2009 Base F inventory was developed, significant concerns related to SO2 and PM were 

encountered. Essentially, what was revealed by the Base F 2009 forecast was a series of apparent 

inconsistencies in the CAIR 2010 and 2015 emission inventories (as compared to the 1996 and 

2020 CAIR inventories) that were masked during the construction of the “longer-term” 

2018 inventory. 

For the most part, the issue seems to be centered on SO2 and PM records, which are those 

records primarily affected by the T4 rule. But, as noted above, there does not seem to be any 

pattern of consistency that would indicate that either inclusion or exclusion of T4 rule impacts is 

the underlying cause. Moreover, where they occur, the observed growth extremes generally 

affect both SO2 and PM equally, while one would expect PM effects to be buffered if the T4 rule

North Carolina Attainment Demonstration June 15, 2007 

60

was the underlying cause, since changes in diesel fuel sulfur content will only affect a fraction of 

PM (i.e., sulfate), while directly reducing SO2. 

While forecast inventories for aircraft, locomotives, and CMV were developed for 2009 and 

2018 using both growth methods, it was ultimately decided to utilize the 1996-2020 growth basis 

since it provided more reasonable growth rates for 2009.

1. INTRODUCTION 

The attainment modeling for the Charlotte-Gastonia-Rock Hill, North Carolina-South Carolina 

nonattainment area (referred to as the Metrolina area) was performed in conjunction with the 

regional haze modeling being done by the Southeast Regional Planning Organization, Visibility 

Improvement State and Tribal Association of the Southeast (VISTAS) and the fine particulate 

matter (PM2.5) and ozone modeling being done by the Association of Southeastern Integrated 

Planning (ASIP). VISTAS and ASIP are run by the ten Southeast states (Alabama, Florida, 

Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West 

Virginia. Since the regional haze and PM2.5 modeling uses annual simulations and includes an 

intermediate year that is the attainment year required for the Metrolina nonattainment area, the 

North Carolina Division of Air Quality (NCDAQ) decided to use the this modeling for its 

attainment demonstration 

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

mobile sources emissions comprise over 50 percent of the emissions of NOx for most of North 

Carolina. 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. In its 

simplest terms, emissions from on-road mobile sources are calculated by multiplying an activity 

level, in this case daily vehicle miles traveled (VMT) as provided by the North Carolina 

Department of Transportation (NCDOT) and Metropolitan Planning Organization (MPOs), by an 

emission factor. 

The US Environmental Protection Agency (USEPA) developed the MOBILE model to estimate 

emission factors based on information on the way vehicles are driven in a particular area. The 

newest version of the MOBILE model, MOBILE6.2, was used. In 2004, MOBILE6.2 was 

incorporated into SMOKEv2.1 which was used in the VISTAS/ASIP modeling. Key inputs for 

MOBILE6.2 include information on the age of vehicles on the roads, the average speed of those 

vehicles, what types of roads those vehicles are traveling on, any control technologies in place in 

an area to reduce emissions for motor vehicles (e.g., emissions inspection programs) and ambient 

temperature. 

A very important component of the on-road mobile emissions estimation process is interagency 

consultation. The Metrolina transportation partners involved in attainment demonstration State 

Implementation Plan (SIP) and motor vehicle emission budget development included: USEPA, 

NCDOT, Federal Highway Administration (FHWA), Gaston Urban Area MPO (GUAMPO), 

Mecklenburg Union MPO (MUMPO), and Cabarrus Rowan MPO. Specifically the NCDOT, 
On-Road Mobile Sources Documentation 2 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

Charlotte Department of Transportation (CDOT) and MPOs were consulted on input data such 

as speeds and VMT derived from the Metrolina travel demand model (TDM). 

The documentation for the on-road mobile sources is broken out into two components: 1) how 

the inventory was developed for the ozone modeling used for the attainment demonstration and 

2) how the motor vehicle emission budgets were developed for the North Carolina counties in 

the Metrolina nonattainment area.

2. MOBILE6.2 INPUT ASSUMPTIONS FOR VISTAS/ASIP 

The MOBILE6 module of SMOKE was used to develop the 2002 and 2009 on-road mobile 

source emissions estimates for carbon monoxide, ammonia, fine particulate matter, nitrogen 

oxides (NOx) and volatile organic compounds (VOCs). The MOBILE6 parameters, vehicle fleet 

descriptions, and VMT estimates were combined with gridded, episode-specific temperature data 

to calculate the gridded, temporalized emission estimates. Of note, whereas the on-network 

emissions estimates are spatially allocated based on link location and subsequently summed to 

the grid cell level, the off-network emissions estimates are spatially allocated based on a 

combination of the FHWA Version 2.0 highway networks and population. For the 

VISTAS/ASIP 36/12 km modeling, no link based data was used. The MOBILE6 emissions 

factors are based on episode-specific temperatures predicted by the meteorological model. 

Further, the MOBILE6 emissions factors model accounts for the following: 

• Hourly and daily minimum/maximum temperatures, relative humidity and barometric 

pressure; 

• Facility speeds; 

• Locale-specific inspection/maintenance (I/M) control programs, if any; 

• Adjustments for running losses; 

• Splitting of evaporative and exhaust emissions into separate source categories; 

• VMT, fleet turnover, and changes in fuel composition and Reid vapor pressure 

(RVP). 

2.1 Speed Assumptions 

Emissions from motor vehicles vary with the manner in which the vehicle is operated. Vehicles 

traveling at 65 miles per hour (mph) emit a very different mix of pollutants than the car that is 

idling at a stoplight. In order to estimate emissions from vehicles for a typical day, NCDOT and 

the MPOs provided speeds for their respective counties. 

The speeds for several urban counties covered by the MPOs were generated from their latest 

travel demand models and are differentiated into the morning rush hours (AM), the evening rush 

hours (PM) and off-peak (OP) speeds. NCDOT recommended using Wake County off-peak 

speeds for all remaining counties in North Carolina. 
On-Road Mobile Sources Documentation 4 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

Interstates are modeled as “non-ramp” instead of “freeways” because both the speed and VMT 

for ramps are included in the functional classification for the major facility it is connected to in 

the travel demand model. This is consistent with the USEPA guidance. 

2.2 Vehicle Age Distribution 

The vehicle age distribution is based on annual registration data for North Carolina and is 

provided by NCDOT. For this analysis the age distribution was generated based on 2004 data, 

representing the latest quality assured information available. The NCDOT provided vehicle 

count data for each vehicle classification from years 1974 through 2004. 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). This vehicle distribution convention corresponds to 

the old MOBILE5 format and does not correlate to the USEPA MOBILE6.2 model vehicle 

types. In order to convert the data provided by the NCDOT into the MOBILE6.2 model format, 

the NCDAQ used a utility developed by the USEPA that disaggregates the 8 MOBILE5 model 

vehicle types into the 16 MOBILE6.2 vehicle types. The count data provided by the NCDOT is 

converted to fractions by dividing each count per vehicle type per year by the total number of 

vehicles in that classification for all years. For example, the number of 2004 light duty vehicles 

divided by the total number of light duty vehicles for all years. The fractions are arranged into 

MOBILE5 format for conversion to the 16 vehicle types required by the MOBILE6.2 model 

using the USEPA conversion utility. 

2.3 Vehicle Mix Assumptions 

2.3.1 North Carolina Statewide Vehicle Mix Development 

The vehicle mix refers to the percentage of different vehicle types on each of the 12 FHWA road 

types. These road types are listed below in Table 2.3.1-1. It is critical for estimating mobile 

emissions in an area to use data that accurately reflects the vehicles types traveling on each of 

these different road types.

On-Road Mobile Sources Documentation 6 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

The NCDAQ created a statewide mix based on the methodology outlined in the August 2004 

USEPA guidance document EPA420-R-04-013, Technical Guidance on the Use of MOBILE6.2 

for Emission Inventory Preparation. Below is the methodology used to convert the 13 Highway 

Performance Monitoring System (HPMS) vehicle types count data reported to FHWA and 

generate a state specific vehicle mix. 

The North Carolina HPMS data that was used to generate the statewide vehicle mix was based 

on 1999 through 2001 data counts. This was the latest available statewide count information at 

the time of the emissions modeling. Table 2.3.1-1 shows the percent of vehicles per vehicle type 

for each of the 12 road classes. 

Disaggregating State Specific Information 

The Technical Guidance on the Use of MOBILE6.2 for Emission Inventory Preparation, Section 

4.1.5, illustrates how to map the HPMS statewide vehicle data to general vehicle categories. 

This mapping is outlined below: 

HPMS Category General Category 

Motorcycle Motorcycle (MC) 

Passenger Car Passenger Car (LDV) 

Other 2-Axel, 4-Tire Vehicles Light Truck (LDT) 

Buses Bus (HDB) 

All Other Trucks: 

 Single unit, 2-axel, 6-tire 

 Single unit, 3-axel 

 Single unit, 4 or more axel 

 Single trailer, 4 or fewer axel 

 Single trailer, 5-axel 

 Single trailer, 6 or more axel 

 Multi-trailer, 5 or fewer axel 

 Multi-trailer, 6-axel 

 Multi-trailer, 7 or more axel 

Heavy Duty Truck (HDV) 

The HPMS data in Table 2.3.1-1 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 2000 fractions were 

used since the state specific data is from 1999 through 2001. The national average data was 
On-Road Mobile Sources Documentation 7 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

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 2.3.1-1 above: 

 Passenger Cars = 56.93% 5 axel Trailer = 19.23% 

 Pickup Trucks = 10.80% 6 axel Trailer = 0.48% 

 Buses = 1.06% 5 axel Multi Trailer = 0.73% 

 2 axel Trucks = 2.50% 6 axel Multi Trailer = 0.24% 

 3 axel Trucks = 1.56% 7 axel Multi Trailer = 0.11% 

 4 axel Trucks = 1.09% Motorcycles = 0.49% 

 4 axel Trailer = 4.79% 

Therefore, the five general categories are: 

Motorcycles = 0.49% 

Light Duty Vehicles = 56.93% 

Light Duty Trucks = 10.80% 

Heavy Duty Buses = 1.06% 

Heavy Duty Vehicles = 30.73% 

From Table 4.1.2 in Technical Guidance on the Use of MOBILE6.2 for Emission Inventory 

Preparation, the 2000 national average vehicle mix for light duty trucks, buses and heavy duty 

trucks are:

2002 NC Statewide Vehicle Mix 

Once the 2000 vehicle mix was generated, the other years were created using the methodology 

described in Technical Guidance on the Use of MOBILE6.2 for Emission Inventory Preparation, 

Section 4.1.4. 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 = 68.22% 

 Heavy Duty Vehicles = 31.78% 

The MOBILE6.2 vehicle mix fractions for the year being developed were obtained from Table 

4.1.2 in Technical Guidance on the Use of MOBILE6.2 for Emission Inventory Preparation. The 

MOBILE6.2 vehicle fractions for 2002 are listed below.

The North Carolina transportation partners recommended the use of the statewide vehicle mix 

for all counties in North Carolina with the exception of the Metrolina area where local vehicle 

count data was incorporated. The development of the Metrolina area vehicle mix is discussed 

below. 

2.3.2 Metrolina Vehicle Mix Development 

Based upon vehicle count data provided by CDOT, a vehicle mix for the Metrolina 

nonattainment area was developed. Vehicle classification counts in the Metrolina nonattainment 

area were gathered using NC-97 (Hi-Star) count machines. The raw counts from the Hi-Star 

count machines are categorized into eight vehicle lengths: less than 20 feet, 20 – 27 feet, 28 – 39 

feet, 40 – 49 feet, 50 – 59 feet, 60 – 69 feet, 70 – 79 feet, 80 feet and greater. In MOBILE6.2, 

vehicles are categorized by weight rather than length. To correlate the vehicle lengths from the 

count data to the vehicle weight used in MOBILE6.2, a methodology employed by the Illinois

Department of Transportation (IDOT) and best engineering judgment was utilized. Table 2.3.2-1 

illustrates the mapping between the count data and the 16 MOBILE6.2 vehicle classifications.

The three vehicle bins, based on vehicle lengths, were grouped into the following general 

categories: Bin 1-Passenger Cars, Light Duty Trucks and Motorcycles, Bin2-Medium Trucks and

The count data collected by CDOT did not include counts on interstates, freeways and local 

roads; therefore, for rural interstates, urban interstates and urban freeways/expressways, the 

statewide vehicle mix was used and collectors were used for local roads. The percentage of each

2.4 Temperature, Relative Humidity and Barometric Pressure Assumptions 

MOBILE6.2 emission factors used by SMOKE are significantly influenced by temperature and 

to a lesser extent, humidity. The most desirable approach from an accuracy standpoint is to 

model on-road mobile emissions using gridded, temporalized data from the meteorological 

model. The VISTAS on-road mobile inventories were developed using this approach. 
On-Road Mobile Sources Documentation 13

North Carolina Attainment Demonstration June 15, 2007 

2.5 Vehicle Inspection and Maintenance Program Assumptions 

In the early 1990’s, North Carolina adopted emissions inspection requirements for vehicles in 9 

urban counties. This program tested emissions at idle for 1975 and newer gasoline powered light 

duty vehicles. This “idle test” was assumed to have a compliance rate of 95 percent and covered 

Gaston, Mecklenburg, Union, Cabarrus Forsyth, Guilford, Orange, Durham and Wake Counties. 

In addition, the inspection stations are required to administer an anti-tampering check to ensure 

that emissions control equipment on any vehicle 35 years old and newer has not been altered. 

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 the 9 counties that 

originally had the “idle test” and was expanded to include a total of 48 counties between July 

2002 and January 2006. Because the OBDII program did not begin until midway through 2002, 

the 2002 annual on-road mobile inventory to support VISTAS/ASIP modeling was developed 

with an “idle test” in the 9 counties listed above plus the anti-tampering in all counties. 

2.6 Reid Vapor Pressure Assumptions 

The RVP is a measure of gasoline’s volatility. The following reflects the RVP settings used in 

the development of the North Carolina on-road mobile inventory to support the VISTAS/ASIP 

regional modeling. An RVP of 7.8 pounds per square inch (psi) is required during May through 

September in the former 1-hour ozone nonattainment areas. The remainder of North Carolina is 

required to have an RVP of 9.0 psi during May through September. 

2.7 Vehicle Miles Traveled Assumptions 

In order to calculate emissions from on-road mobile sources, emission factors are developed as 

discussed throughout this document. The emission factors are then multiplied by an activity 

level, which for on-road mobile sources is VMT. 

For most counties in North Carolina, the 2002 VMT was derived from the 2002 Highway 

Performance Maintenance System (HPMS) data provided by NCDOT and the 2009 was grown 

based on a linear interpolation of the most recent 10 years (1995-2004) of HPMS data. Like with 

the speed data explained above, VMT from several urban counties travel demand models were 

used instead of HPMS VMT. Where this travel demand model data was available, it was the 

recommendation of the North Carolina transportation partners to use it instead of the HPMS 

data.
On-Road Mobile Sources Documentation 14 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

In situations where certain North Carolina counties are partially covered by a travel demand 

model, and the North Carolina transportation partners anticipate future versions of the travel 

models to cover the entire county, an adjusted HPMS VMT number was used. This upward 

adjustment (30%) of the countywide HPMS VMT data is based on an analysis by NCDAQ that 

shows that travel demand model VMT can be as much as 30% higher than the HPMS VMT. In 

some counties that the transportation partners felt were in high growth areas that may not be 

captured in the HPMS VMT growth process, an additional 10% growth was added to the 2009 

projected HPMS VMT. 

In the Metrolina area, all of the counties, with the exception of Iredell County, was fully covered 

by a TDM and TDM VMT was used in the attainment demonstration modeling. For Iredell 

County, only part of the county was covered by the regional TDM and therefore HPMS data was 

used. At the request of the transportation partners, during the interagency consultation process, 

the VMT used in the attainment demonstration for Iredell County was increased by 40%.

3. MOBILE6.2 INPUT ASSUMPTIONS FOR MOTOR VEHICLE 

EMISSION BUDGETS 

The purpose of transportation conformity is to ensure that Federal transportation actions 

occurring in a nonattainment areas does not hinder the area from maintaining the 8-hour ozone 

standard. This means that the level of emissions estimated by the NCDOT or the MPOs for the 

Transportation Implementation Plan and Long Range Transportation Plan must not exceed the 

motor vehicle emission budgets (MVEBs) as defined in this attainment demonstration SIP. 

The sections below describe the MOBILE6.2 input assumptions used to calculate the MVEBs. 

The MOBILE6.2 input files and output files used in the development of the on-road mobile 

source emissions for the attainment demonstration are compiled in Section 5. 

As stated in the introduction, a very important component of the on-road mobile emissions 

estimation process is interagency consultation. The Metrolina transportation partners involved in 

attainment demonstration State Implementation Plan (SIP) and motor vehicle emission budget 

development included: USEPA, NCDOT, Federal Highway Administration (FHWA), Gaston 

Urban Area MPO (GUAMPO), Mecklenburg Union MPO (MUMPO), and Cabarrus Rowan 

MPO. Specifically the NCDOT, Charlotte Department of Transportation (CDOT) and MPOs 

were consulted on input data such as speeds and VMT derived from the Metrolina travel demand 

model (TDM), as well the other input parameters discussed below. 

3.1 Speed Assumptions 

The MOBILE6.2 command “AVEAGE SPEED” was used to enter the speeds. This command 

requires the average speed on a given roadway scenario. Interstates are modeled as “non-ramp” 

instead of “freeways” because both the speed and VMT for ramps are included in the functional 

classification for the major facility it is connected to in the travel demand model. This is 

consistent with the USEPA guidance. 

In order to estimate emissions from vehicles for a typical day, CDOT and the MPOs provided 

speeds for their respective counties. The speeds were generated from their latest travel demand 

model at the time of the VISTAS/ASIP modeling. These speeds were provided based on a daily 

average. 

As part of the public comment process, the NCDOT requested that four times a day speeds be 

used instead of average daily speeds since this would be consistent with how future 

transportation conformity regional emissions analyses will be performed. CDOT and MUMPO 

both commented on this inconsistency as well, especially for the motor vehicle emission budgets 
On-Road Mobile Sources Documentation 16

for Iredell, Mecklenburg and Union Counties. It did not appear that the other transportation 

partners were consulted about this request, therefore, the NCDAQ has decided to not to use the 

new data for setting the MVEBs. The NCDAQ will share this data with the transportation 

partners in an interagency consultation meeting, to be set at a later date. Additionally, there were 

a number of questions and concerns in the NCDAQ’s initial review of the data. If the questions 

and concerns the NCDAQ have with the data are resolved and all transportation partners agree 

that the new data should be used in setting the MVEBs, then the NCDAQ will determine the 

effects of the new data on emissions, as well as on the attainment demonstration modeling. If the 

new data does not jeopardize the attainment demonstration modeling, the NCDAQ may start a 

SIP revision process, if deemed appropriate, to incorporate the new data into the MVEBs 

calculations. 

Table 3.1-1 below provides a summary of the speeds used for the development of the MVEBs. 

These same speeds were used in the 2009 VISTAS/ASIP modeling for all counties except Iredell 

County. Only a small portion of Iredell County was designated nonattainment (Coddle Creek 

and Davidson Townships). For the VISTAS/ASIP modeling, average county-wide speeds were 

used, for the setting of the MVEBs, average speeds based on just the nonattainment area are 

used. The column headings in Table 3.1-1 represent the 12 FHWA road types used in the 

modeling and are listed below. The 12 FHWA road types are:

3.2 Vehicle Age Distribution 

The vehicle age distribution used in developing the MVEBs is the same as what was used in the 

VISTAS/ASIP modeling and is discussed in Section 2.2. A copy of this vehicle age distribution 

can be found in Section 5 of this document. 

As part of the public comment process, the NCDOT requested that new vehicle age distribution 

data be used instead of the data used in the 2009 VISTAS/ASIP modeling. It did not appear that 

the other transportation partners were consulted about this request, therefore, the NCDAQ has 

decided to not to use the new data for setting the MVEBs. The NCDAQ will share this data with 

the transportation partners in an interagency consultation meeting, to be set at a later date. If all 

transportation partners agree that the new data should be used in setting the MVEBs, then the 

NCDAQ will determine the effects of the new data on emissions, as well as on the attainment 

demonstration modeling. If the new data does not jeopardize the attainment demonstration 

modeling, the NCDAQ may start a SIP revision process, if deemed appropriate, to incorporate 

the new data into the MVEBs calculations. 

3.3 Development of Vehicle Mix 

The vehicle mix used in the developing of the MVEBs is the Metrolina area vehicle mix 

discussed in Section 2.3.2. 

As part of the public comment process, the NCDOT requested that new vehicle mix data be used 

instead of the data used in the 2009 VISTAS/ASIP modeling. It did not appear that the other 

transportation partners were consulted about this request, therefore, NCDAQ has decided to not 

to use the new data for setting the MVEBs. The NCDAQ will share this data with the 

transportation partners in an interagency consultation meeting, to be set at a later date. If all 

transportation partners agree that the new data should be used in setting the MVEBs, then the 

NCDAQ will determine the effects on the emissions as well as on the attainment demonstration 

modeling. If the new data does not jeopardize the attainment demonstration modeling, the 

NCDAQ may start a SIP revision process, if deemed appropriate, to incorporate the new data 

into the MVEBs calculations. 

The Metrolina vehicle mix data used in setting the MVEBs can be found in Section 5 of this 

document.

3.4 Temperature, Relative Humidity and Barometric Pressure Assumptions 

The MOBILE6.2 command “HOURLY TEMPERATURES” was used to enter temperatures to 

estimate mobile source emissions. This command requires the command name followed by the 

hourly temperatures in the data field in the RUN SECTION of the MOBILE6.2 input files. The 

relative humidity command used in MOBILE6.2 is “RELATIVE HUMIDITY” followed by the 

hourly relative humidity data. The “RELATIVE HUMIDITY” command is placed in each 

SCENARIO SECTION in the input files. For the Metrolina nonattainment area, the NCDAQ 

used an average July 2002 hourly temperature profile and relative humidity profile from the 

Charlotte-Douglas International Airport Meteorological Station. The hourly temperatures and 

relative humidity are shown in Tables 3.4-1.

3.5 Vehicle Inspection and Maintenance Program Assumptions 

The ODBII program is administered in all of the counties in the Metrolina nonattainment area. 

Mecklenburg, Gaston, Union and Cabarrus Counties were four of the original nine counties that 

implemented the OBDII program. Iredell and Rowan Counties were phased-in in July 2003 and 

Lincoln County was phased-in in January 2004. All counties in North Carolina have a vehicle 

safety inspection program. Inspection stations are required to administer an anti-tampering 

check to ensure that emissions control equipment on any vehicle, less than 35 model years old, 

has not been altered. 

3.6 Reid Vapor Pressure Assumptions 

As discussed in Section 2.6, the RVP is required to be 7.8 psi during May through September in 

areas that were nonattainment for the 1-hour ozone standard, which includes Gaston and 

Mecklenburg Counties. The remaining counties in the Metrolina nonattainment area are required 

to have an RVP of 9.0 psi during May through September. These values were used in 

calculating the MVEBs for the Metrolina nonattainment area. 

3.7 Vehicle Miles Traveled Assumptions 

In order to calculate emissions from on-road mobile sources, emission factors are developed as 

discussed throughout this document. The emission factors are then multiplied by an activity 

level, which for on-road mobile sources is daily VMT. 

The daily VMT for the Metrolina nonattainment area was provided by CDOT on February 18, 

2005. The 2009 VMT data used to calculate the MVEBs is the same data that was used in the 

Metrolina attainment demonstration SIP with the exception of Iredell County. The VMT used 

for Iredell County in the attainment demonstration was an adjusted HPMS, where the HPMS 

data was increased by 40% at the request of the transportation partners. Thirty percent was to 

make the VMT TDM-like and ten percent to account for the high growth in this area. As stated 

earlier, only part of Iredell County was designated nonattainment, so the VMT used to estimate 

the MVEB reflects TDM VMT associated with the nonattainment area only. This VMT was 

then increased by 10% to account for the high growth in this area per the interagency 

consultation process. 

As part of the public comment process, the NCDOT requested that four times a day VMT be 

used instead of daily VMT since this would be consistent with how future transportation 

conformity regional emissions analyses will be performed. CDOT and MUMPO both

commented on this inconsistency as well, especially for the motor vehicle emission budgets for 

Iredell, Mecklenburg and Union Counties. It did not appear that the other transportation partners 

were consulted about this request, therefore, the NCDAQ has decided to not to use the new data 

for setting the MVEBs. The NCDAQ will share this data with the transportation partners in an 

interagency consultation meeting, to be set at a later date. Additionally, there were a number of 

questions and concerns in the NCDAQ’s initial review of the data. If the questions and concerns 

the NCDAQ have with the data are resolved and all transportation partners agree that the new 

data should be used in setting the MVEBs, then the NCDAQ will determine the effects of the 

new data on emissions, as well as on the attainment demonstration modeling. If the new data 

does not jeopardize the attainment demonstration modeling, the NCDAQ may start a SIP 

revision process, if deemed appropriate, to incorporate the new data into the MVEBs 

calculations.

4. MOTOR VEHICLE EMISSIONS BUDGETS FOR CONFORMITY 

4.1 Transportation Conformity 

As mentioned earlier, the purpose of transportation conformity is to ensure that Federal 

transportation actions occurring in a nonattainment areas does not hinder the area from 

maintaining the 8-hour ozone standard. This means that the level of emissions estimated by the 

NCDOT or the MPOs for the Transportation Implementation Plan and Long Range 

Transportation Plan must not exceed the MVEBs as defined in this attainment demonstration 

SIP. 

One of the requirements is that the NCDAQ needs to consult with the transportation partners in 

the development of the SIP. The NCDAQ consulted the partners for the data used in the 

development of the MVEBs, as well as the data used in the VISTAS/ASIP modeling. 

Additionally, the NCDAQ sent out a request for comment on setting the geographic extent of the 

MVEBs to all of the transportation partners. A copy of the letter can be found in Appendix B. 

In the letter, NCDAQ expressed its preference for setting county level budgets and some of the 

reasons why NCDAQ believed county level budgets were appropriate. 

The NCDAQ received comments from several of the transportation partners regarding the 

geographic extent of the MVEBs. Some of the partners wanted county-by-county budgets; 

others wanted regional budgets. Copies of the letters received can be found in Appendix B. 

Upon careful consideration of all arguments, the NCDAQ decided to move forward with setting 

county level MVEBs. The NCDAQ believes that since mobile source NOx emissions play a 

significant role in the ozone formation in the Metrolina nonattainment area, it is important that 

the larger, more urbanized counties in the area meet the county level NOx MVEBs that closely 

represents the emissions that were modeled for the attainment demonstration. 

4.2 Highway Mobile Source VOC Insignificance 

Section 93.109(k) in the Transportation Conformity Rule Amendments for the new 8-hour ozone 

and fine particulate matter NAAQS addresses areas with insignificant motor vehicle emissions. 

It reads: 

Notwithstanding the other paragraphs in this section, an area is not required to satisfy a 

regional emissions analysis for §93.118 and/or §93.119 for a given pollutant/precursor 

and NAAQS, if EPA finds through the adequacy or approval process that a SIP 

demonstrates that regional motor vehicle emissions are an insignificant contributor to 

the air quality problem for that pollutant/precursor and NAAQS. The SIP would have to 

demonstrate that it would be unreasonable to expect that such an area would experience 
On-Road Mobile Sources Documentation 22 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

enough motor vehicle emissions growth in that pollutant/precursor for a NAAQS 

violation to occur. 

The rule suggests that such a finding would be based on a number of factors, including the 

percentage of motor vehicle emissions in the context of the total SIP inventory, the current state 

of air quality as determined by monitoring data for that NAAQS, the absence of SIP motor 

vehicle control measures, and historical trends and future projections of the growth of motor 

vehicle emissions. Although there is a vehicle control measure in place in the Metrolina area, an 

inspection and maintenance program, the current program was established for additional 

reductions in NOx emissions. There are incidental VOC emission reductions as a result of this 

program (~ 8%), however, it is not believed the reduction of VOC emissions results in decreased 

ozone levels. 

The NCDAQ has examined the sources of VOC emissions and their contribution to ozone 

formation in North Carolina. Due to the generally warm and moist climate of North Carolina, 

vegetation abounds in many forms, and forested lands naturally cover much of the state. The 

biogenic sector is the most abundant source of VOC emissions in North Carolina and accounts 

for approximately 90% of the total VOC emissions statewide. The overwhelming abundance of 

biogenic VOC emissions makes the majority of North Carolina a NOx limited environment for 

the formation of ozone. This holds true for the Metrolina nonattainment area counties. 

Summaries from the VISTAS/ASIP 2002 and 2009 regional modeling effort were used to 

illustrate the abundance of the biogenic VOC emissions. Figures 4.2-1 and 4.2-2 provides the 

percent contributions from point, on-road mobile, off-road mobile, area, and biogenic sources to 

the total VOC emissions in the Metrolina nonattainment area in 2002 and 2009, respectively. 

For the two partial counties in the Metrolina nonattainment area, Iredell and York Counties, the 

whole county emissions were used since the modeling inventories are for whole counties.

Figure 4.2-2 Metrolina Area 2009 Daily Summertime VOC Emissions 

In the Metrolina nonattainment area, on-road mobile sources contribute only 15 and 9 percent of 

the 2002 and 2009 total VOC inventories, respectively. 

Also noteworthy are the projected decreases in on-road mobile VOC emissions, notwithstanding 

VMT increases. These reductions are due mainly to the retirement of older vehicles and the 

growing fleet of Tier 2 vehicles on the roads in future years. Some additional reductions are 

attributable to North Carolina’s I/M program in the Metrolina area. 

A recent modeling sensitivity test was performed by ASIP that allows an analysis of VOC 

contributions to ozone concentrations in the Southeastern United States. One of the analyses 

conducted by ASIP is a series of emissions sensitivity modeling runs to quantify the 

contributions of various emission sources to ozone and fine particles. The modeling system used 

in this analysis consisted of 3 components: 1) the Penn State University/National Center for 

Atmospheric Research Mesoscale Model (MM5 version 3.6.1+), 2) the Sparse Matrix Operator 

Kernel Emissions Modeling System (SMOKE version 2.1), and 3) the Community Multiscale 

Air Quality (CMAQ version 4.4) model. Model configurations, input data, and modeling 

methods are consistent with those suggested by the USEPA in Guidance on the Use of Models 

and Other Analyses in Attainment Demonstrations for the 8-hour Ozone NAAQS.

North Carolina Attainment Demonstration June 15, 2007 

The emissions sensitivities are calculated by taking the difference between two air quality model 

simulations: one with base case emissions and another with reduced emissions inputs. The 

emissions sensitivity discussed here reduces all anthropogenic VOCs in the modeling domain by 

30% from 2009 emission levels. Translating this to the Metrolina nonattainment area emissions, 

this 30% anthropogenic VOC reduction is equivalent to about a 70% reduction of all on-road 

mobile VOC emissions in the Metrolina nonattainment area in 2009. This emissions sensitivity 

was run for a 39 day period (June 1-July 9). In all 39 days of the modeling simulation, the 8-

hour ozone maximum concentrations were unchanged in the Metrolina nonattainment area – a 

clear indicator that on-road mobile VOC is an insignificant contributor to ozone formation in that 

area. In fact, there was not an 8-hour ozone response as high as 1 ppb anywhere in North 

Carolina during the sensitivity simulation. Figure 4.2-3 provides an example from the 30% 

anthropogenic VOC reduction modeling illustrating the lack of ozone response North Carolina. 

Figure 4.2-3 8-hour Ozone response to 30% anthropogenic VOC reductions in 2009 

Additional mobile source sensitivity simulations have been conducted by the NCDAQ. These 

modeling runs focused specifically on the impact of mobile source VOC emissions on ozone. 

The sensitivity reduced mobile source VOC by 50% in the North Carolina counties in the 

Metrolina ozone nonattainment area (Cabarrus, Gaston, Iredell, Lincoln, Mecklenburg, Rowan 

and Union Counties) in the year 2008. This emissions sensitivity was run for a 7 day period 
On-Road Mobile Sources Documentation 25 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

(July 13-19). In all 7 days of the modeling simulation, the 8-hour ozone maximum 

concentrations were unchanged in the Metrolina nonattainment area (and all of North Carolina), 

a clear indicator that on-road mobile VOC is an insignificant contributor to ozone formation in 

that area. Figure 4.2-4 provides an example of the lack of an 8-hour ozone response from the 

50% mobile VOC reduction sensitivity modeling. 

Figure 4.2-4 8-hour Ozone Response to 50% mobile VOC decrease in 2008 

Based on the information discussed above, the NCDAQ steadfastly believes on-road mobile 

VOCs are insignificant contributors to ozone formation in the Metrolina nonattainment area. 

Emission estimates indicate on-road mobile VOC is a small percentage of the total VOC 

emissions inventory. On-road mobile VOC emissions are projected to decrease into the future 

notwithstanding VMT increases. The area is currently below the NAAQS and emission 

sensitivity modeling performed by ASIP and the NCDAQ indicates no change in future ozone 

concentrations when VOC emissions are significantly changed. Further, the NCDAQ considers 
On-Road Mobile Sources Documentation 26 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

it unreasonable to expect that the Metrolina nonattainment area will experience enough motor 

vehicle VOC emissions growth for a future ozone violation to occur. For these reasons, the 

NCDAQ presented the VOC insignificance concept to the transportation partners and all agreed 

through the interagency consultation process that mobile source VOC emissions were 

insignificant. Therefore, the NCDAQ will not be setting MVEB for VOC for the Metrolina 

nonattainment area. 

An affirmative insignificance finding from the USEPA only relieves the transportation partners 

from a regional emissions analysis for VOC emissions for this area and does not relieve them of 

the other transportation conformity requirements. The transportation partners will need to note 

the VOC insignificance finding (if found adequate and approved by the USEPA) in future 

conformity determinations. 

4.3 Motor Vehicle Emission Budgets 

As part of the consultation process on setting MVEBs, the NCDAQ sent out a request for 

comment on setting the geographic extent of the MVEBs to all of the transportation partners. A 

copy of the letter can be found in Appendix B. In the letter, the NCDAQ expressed its 

preference for setting county level budgets and some of the reasons why the NCDAQ believed 

county level budgets were appropriate. 

The NCDAQ received comments from several of the transportation partners regarding the 

geographic extent of the MVEBs. Some of the partners wanted county-by-county budgets; 

others wanted regional budgets. Copies of the letters received can be found in Appendix B. 

Upon careful consideration of all arguments, the NCDAQ decided to move forward with setting 

county level MVEBs. The NCDAQ believes that since mobile source NOx emissions play a 

significant role in the ozone formation in the Metrolina area, it is important that the large 

counties in the area meet the county level NOx MVEBs that closely represents the emissions that 

were modeled for the attainment demonstration. 

The MVEBs will be set for the attainment year 2009. By the time the MVEBs are found 

adequate or approved by the USEPA, the next transportation conformity regional emissions 

analysis should be for years 2009 and beyond. Therefore, MVEBs will not be set for the 

baseline year 2002. 

Although the emissions are usually expressed in terms of tons per day, the MVEBs will be set in 

terms of kilograms (kg) per day. The reason for the change is because the MOBILE model 

generates the emissions factors in grams per mile. In past conformity exercises, there have been 
On-Road Mobile Sources Documentation 27 

The Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Appendix F.3 

North Carolina Attainment Demonstration June 15, 2007 

some issues with conversion to tons per day, as well as concerns with how the MVEBs were 

rounded to the hundredth place. Setting MVEBs in kilograms per day will avoid these issues in 

future conformity determinations. 

The table below shows the North Carolina counties with their on-road mobile NOx emissions 

expressed in tons per day and the corresponding kilograms per day values for 2009.

the Metrolina nonattainment area for 2009. Tables 4.3-2 below list out the NOx MVEBs in 

kilograms per day, for transportation conformity purposes, by county. Upon the USEPA’s 

affirmative adequacy finding for these county level sub-area MVEBs, these MVEBs will become 

the applicable MVEBs for each county.
