# Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018, Em ission Inventories for VISTAS

Introduction

Base G2 document was delivered final in Aug (?) 2007. In fall 2007 states updated specific point source EGU and non-EGU fac ility record in Best and Final (B&F)
inventories for 2009 and 2018 to account for BART controls, consent decrees, corrections to Base G2, and source specific controls. Only EGU and non-EGU point source records were changed. Area, non-road, on-road remained the same as Base G2. In this report all records for area, non-road, and on-road were used in B&F modeling the same as Base G2. This report has been updated from the Base G2 report submitted in July 2007 just for B&F changes to EGU and non-EGU sources. A history of the development of the VISTAS inventory follows. Specific sections of the document detail the modifications made as the inventory progre ssed from Base F through B&F.

The Base G2 inventory included changes in 2018 controls on specifi c electric generating units in GA, FL, NC, and WV. There were no changes in 2009 controls for EGU and no changes between the Base G and Base G2 inventories for non-EGU point, on-road, nonroad, or area sources in 2009 or 2018. The Base G2 modeling run included changes for 2018 EGU controls plus corrections in 2002 typical, 2009, and 2018 for errors in emissions processing in Base G. These corr ections in emissions processing are not seen when comparing the Base G and G2 inventory files.

Base G and Base G2 inventories represent tw o separate model runs, as does the B&F. Since Base G2 supersedes Base G, VISTAS will maintain only the Base G2 and B&F model files since both were used in State Implementation Plan submittals.

History of VISTAS Base and Projection Year Emission Inventory Development

This section is provided to supply the hist ory behind the development of the base and projection year inventories pr ovided to the Visibility Im provement State and Tribal Association of the Southeast (VISTAS) and the Association for Southeast Integrated Planning (ASIP). Through the various itera tions, the inventories that have been developed have typically had version numbers provide d by the contractors who developed the inventories and to a certain extent these were also based on their purpose. Different components of th e 2002 base year inventories have been supplied by E.H. Pechan and Associates, Inc. (Pechan), MACTEC Engineering and Consulting, Inc.

# (MACTEC), and by Alpine Geophysics, Inc. ( AG). The projection year inventories were developed by MACTEC and AG.

The initial 2002 base year inventory was jointly developed by Pechan and MACTEC. Pechan developed the on-road and non-road mobile source components of the inventory while MACTEC developed the point and area source component of the inventory. This version of the inventory included updates to on-road mobile that incorporated information from the 1999 NEI Version 2 final along with updated information on VMT, fuel programs, and other input s to the MOBILE6 model to pr oduce a draft version of the 2002 inventory. For non-road sources, a sim ilar approach was used. Updated State information on temperatures and fuel characte ristics were obtained from VISTAS States
and used with the NONROAD 2002 model to calculate 2002 emissions for NONROAD model sources. These estimates were coupled with data for commercial marine vessels, locomotives and airplanes projected to 2002 us ing appropriate growth surrogates. A draft
version of these inventories wa s prepared in late 2003, with a final version in early 2004. An overview of the development of the on-road component can be found at: http://www.vistas-sesarm.org/documen ts/Pechan_drafton-roadinventory_082803.ppt
while an overview of the non-road component can be found at: http://www.vistas-sesarm.org/docum ents/Pechan_Non-roadInventory_082803.ppt

. Similarly, draft versions of the 2002 point a nd area source base year inventories were prepared by MACTEC in the same timeframe (late 2003 for the draf t, final in early 2004). The point source component was based on data submitted by the VISTAS States or on the 1999 NEI. The data submitted by the States ranged from 1999 to 2001 and was all projected to 2002 using appropriate gr owth surrogates from Economic Growth Analysis System (EGAS) version 4. Toxic Rel ease Inventory (TRI) data were used to augment the inventory for NH 3 

# . Continuous Emissions Monitor (CEM) data from the
U.S. EPA’s Clean Air Markets Division wa s used to supply emissions for electric generating utilities (EGUs). Particulate matte r emissions were augmented (when missing) by using emission factor ratios. Details on all these calculations are discussed in
Section 1.1.1.3 of this document.

The area source component of the 2002 draft base year emissions was prepared similarly to the point sources, using State submittals and the 1999 NEI Version 2 final as the basis for projecting emissions to 2002 using EGAS growth factors. For ammonia area sources the Carnegie Mellon University (CMU) ammoni a model was used to calculate emissions. Finally, data on acreage burned on a fire by fire basis was solicited from State forestry agencies in order to calculate fire emissions on a fire by fire basis. Virtually all VISTAS State forestry agencies provided data for these calculations at least for wild and

.

Three interim versions of th e 2002 base year inventory we re developed. The first was delivered in August of 2003, the second in Ap ril of 2004 and the final one in October of 2004. The August 2003 and April 2004 inventor ies were prepared by MACTEC and
Pechan. A draft version of the revised 2002 base year inventory was released in June of 2004, with a final version released in Oct ober 2004. That 2002 base year inventory was solely prepared by MACTEC. The Oct ober 2004 inventory incorporated 2002 Consolidated Emissions Reporting Rule (CERR) data into the inve ntory along with some updated data from the VISTAS States. This inve ntory is typically referred to as version 3.1 of the VISTAS inventory.

Closely following the version 3.1 2002 ba se year inventory, a “preliminary” 2018 projection inventory was devel oped. This “preliminary” 2018 inventory was developed in late 2004 (Oct/Nov) and was designed solely for use in modeling sensitivity runs to provide a quick and dirty assessment of what “on the books” and “ on the way” controls could be expected to provide in terms of improvements to visibility and regional haze impairment. A brief overview of the history of the three versions of the 2002 base year and the 2018 preliminary inventory use can be found at: http://www.vistassesarm.org/documents/STAD1204/2002and2018Emissions14Dec2004.ppt

. Following preparation of the final 3.1 versi on of the 2002 base year inventory, States were asked to review and provide comments on that inventory to MACTEC for update and revision. At the same time MACTEC pr epared a revised draf t version of the 2018 projection inventory (January 2005) and a dr aft version of a 2009 projection inventory (April 2005). All of these were known as vers ion 3.1 and were provided to the VISTAS
States for review and comment. Comments were received and updates to the inventories based on these comments were prepared. The revised inventories we re provided to the
VISTAS States. At that time to be consiste nt with the modeling nomenclature being used by AG in performing their modeling runs, th e inventory became the Base F VISTAS inventory. The Base F inventory was deliver ed for review and comment in August of 2005. In addition, MACTEC deliv ered a report entitled Documentation of the Revised 2002 Base Year, Revised 2018, and Initial 2009 Emission Inventories for VISTAS on August 2, 2005 that described the methods used to develop the Base F inventories. For the Electric Generating Utilities (EGU) different versions of the Integrated Planning Model were used between Base D and Base F, resulting in different projections of future
EGU emissions.

# Over the period from August 2005 until J une/July 2006 MACTEC received comments and updates to some categories from VISTAS States, particularly EGU. In addition, a new NONROAD model (NONROAD05) was released. Thus a dditional updates to the inventory were prepared based on the comm ents received along with revised NONROAD
emission estimates from NONROAD05. The resultant inventory became the Base G inventory.

Following release of the Base G inventory in early 2007, four States specified additional changes to reflect their best estimates of EGU emission leve ls and controls in 2018. The resulting 2018 EGU emission inventory is referr ed to as Base G2, which was released in July 2007.

The current version of the VISTAS inventory is referred to as the “Best and Final (B&F)” inventory. States specified additional change s to the point source inventory to reflect improved knowledge of EGU emission levels and controls in 2009 and 2018. States also specified changes to nonEGU sources reflectin g new information on anticipated controls and shutdowns. No changes to any other sour ce sector (e.g., area, fire, nonroad, onroad) were made for the B&F inventory. The 2018 B&F inventory was released in October 2007, and the 2009 B&F inventory was released in December 2007.

This document details the development of the Base G/G2/B&F inventories for 2002,
2009 and 2018. The information that follows de scribes the development of the VISTAS inventory by sector from Base F forward. Unless specific updates were made to an inventory sector, the methods used for Base F were retained. Table I-1 through Table I-3 indicate roughly which version of the inventor y is in use for each sector of the inventory as of the B&F inventory.

Under a separate contract, AG was asked to obtain and convert emission inventory data for the five states that make up the Midwest Regional Planning Organization (MRPO) for use by VISTAS/ASIP modelers. De tails of this effort are doc umented in an Appendix to this report.

# 1.0 2002 Base Year Inventory Development

1.1 Point Sources

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 the Visibility Improvement State and
Tribal Association of he Southeas t (VISTAS) States and local (S/L ) agencies to the United States Environmental Protection Agency (EPA) as part of the Consolidated Emissions Reporting Rule (CERR) requirements Work on incorporating the CE RR data into the revise d base year involved: 1) obtaining the data from EPA or the S/L agency, 2) evaluating the emissions and pollutants reported in the CERR submittals, 3) augmenting CERR data with annual emission estimates for
PM 10 

# -PRI and PM 2.5 

# -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 in formation from S/L agencies based on their review of the 2002 inventory. The processes used to perform those operati ons are described in the first portion of this section.

The second component was the development of a “typical” year inventory for electric generating units (EGUs). VISTAS determined that a typica l year electric generating units (EGU) inventory was necessary to smooth out any anomalies in emissions from the EGU sector due to meteorology, economic, and outage factors in 2002. The typical year EGU inventory is intended to represent the five year (2000-2004) period that will be used to determine the regional haze reasonable progress goals. The second part of this section discusses the development of the typical year EGU inventory.

1.1.1 Development of 2002 Point Source Inventory
MACTEC developed a draft 2002 em ission inventory in June 2004 ( Development of the Draft 2002 VISTAS Emission Inventory for Regi onal Haze Modeling – Point Sources , MACTEC, June 18, 2004). The starting point for the dr aft 2002 emission inventory was EPA’s 1999 National Emission Inventory (NEI), Version 2 Final (NEI99V2). Fo r several states, we replaced
the NEI99V2 data with more recent inventorie s for either calendar year 1999, 2000, or 2001 as submitted by the S/L agencies. We also performed several other updates, including updating emission estimates for selected large source of ammonia, incorpor ating 2002 Continuous Emissions Monitoring-(CEM)-based SO 2 

# and NO x 

# emissions for electric utilities, adding PM 10 

# and PM 2.5 

# emissions when they were missing from an S/L submittal, and performing a variety of additional Quality assurance/Quality control (QA/QC) checks.

# The next version of the 2002 inventory (referred to as Base F) was released in August 2005 ( Documentation of the Revised 2002 Base Year, Revised 2018, and Initial 2009 Emission Inventories for VISTAS , MACTEC, August 2, 2005). The primary task in preparing the Base F 2002 base year inventory was the replacement of NEI99V2 data with data submitted by the VISTAS S/L agencies as part of the CERR submittal and included in EPA’s 2002 NEI.

The next version of the 2002 inventory (referred to as Base G) was released in August 2006 and is documented in this report. The primary task in preparing the Base G 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 Base F inventory. Note that no changes to the Base G 2002 point source inventory were made during the Base G2 and B&F update cycles (in other words, for the 2002 actual and typical inventories, Base G = Base G2 = B&F).

The following subsections document the data sour ces for the Base G/B&F inventory, the checks made on the CERR submittals, the process for augmenting the inventory with PM 10 

# and PM 2.5 

# emissions, the evaluation of EGU emissions, ot her QA/QC checks, and other Base G updates.
The final subsection summarizes the Base G/B&F 2002 inventory by state, pollutant, and sector (EGU and non-EGU).

1.1.1.1 Data Sources
Several data sources were used to compile the Ba se F point source inventor y: 1) the inventories that the S/L submitted to EPA from May through July 2004 as required by the CERR; 2) supplemental data supplied by the S/L agencies that may have been revised or finalized after the CERR submittal to EPA, and 3) the draft VISTAS 2002 inventory in cases where S/L CERR
data were not available. For the Base G inve ntory, we replaced data from Hamilton County, Tennessee, using data from Hamilton County’s CERR submittal as contained in EPA’s 2002 NEI inventory (in Base F, the inventory for Hamilton County was based on the draft VISTAS 2002 inventory, which in turn wa s based on the 1999 NEI).

Table 1.1-1 summarizes the data used as the st arting point for the Base F 2002 inventory. Once all of the files were obtained, MACTEC ra n the files through the EPA National Emission Inventory 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. In a couple of cases small errors were found. For example, in one case non-standard pollutant designations were used for particul ate matter (PM) and ammo nia emissions. MACTEC contacted each VISTAS State poin t source contact person to resolve the issues with the files and
corrections were made. Once all corrections to the native files were made, MACTEC continued with the incorporation of the data into the VIST AS point source files. S/L agencies completed a detailed review of the Base F inventory. A dditional updates and corrections to the Base F

# 1.1.1.2 Initial Data Evaluation
For the Base F inventory, we conducted an ini tial review of the 2002 poi nt source CERR data in accordance with the QA procedures specified in th e Quality Assurance Proj ect Plan (QAPP) for this project. The following evaluations were co mpleted to identify potential data quality issues
associated with the CERR data:

 

# Compared the number of sites in the CERR su bmittal to the number of sites in the VISTAS draft 2002 inventory; for all States, the number of sites in the CERR submittal
was less than in the VISTAS draft 2002 inve ntory, since the CERR data was limited to major sources, while the VISTAS draft 2002 in ventory contained data for both major and minor sources; verified with S/L contacts th at minor sources not included in the CERR point source inventory were included in the CERR area source inventory.

# Checked for correct pollutant codes and co rrected to make them NIF-compliant; for example, some S/L agencies reported ammoni a emissions using the CAS Number or as “ammonia”, rather than the NIF-compliant “NH 3 

# ” code.

 

# Checked for types of particulate matter c odes reported (i.e., PM-FIL, PM-CON, PM-PRI,

PM 10 

# -PRI, PM10-FIL, PM 2.5 

# -PRI, PM 2.5 

# -FIL); corrected codes with obvious errors (i.e., changed PMPRI to PM-PRI). (The PM augmentation process for filling in missing PM pollutants is discussed later in Section 1.1.1.3)

 

# Converted all emission values that weren’t in tons to tons to allow for preparation of emission summaries using consistent units.

 

# Checked start and end dates in the PE and EM tables to confirm consistency with the 2002 base year.

 

# Compared annual and daily emissions when daily emissions were reported; in some cases, the daily value was non-zer o (but very small) but the annual value was zero. This was generally the result of rounding in an S/L agency’s submittal.

 

# Compared ammonia emissions as reported in the CERR submittals and the 2002 Toxics Release Inventory; worked with S/L agencies to resolve any outstan ding discrepancies.

 

# Compared SO 2 

# and NO x 

# emissions for EGUs to EPA’s Clean Air Markets Division CEM database to identify any outstanding discre pancies. (A full discussion of the EGU emissions analysis is discu ssed later in Section 1.1.1.4)

 

# Prepared State-level emission summaries by pollutant for both the EGU and non-EGU sectors to allow S/L agencies to compar e emissions as repo rted in the 1999 NEI Version 2, the VISTAS draft 2002 i nventory, and the CERR submittals.

 

# Prepared facility-level emissi on summaries by pollutant to al low S/L agencies to review facility level emissions for reasonableness and accuracy.

We communicated the results of these analyses through email/telephone exchanges with the S/L point source contacts as well as through Excel summary spreadsheets. S/L agencies submitted corrections and updates as necessary to reso lve any QA/QC issues from these checks.

S/L agencies did not report PM emissions in a consistent manner. The State/local inventories submitted for VISTAS included emissions data for either PM-FIL, PM-PRI, PM 10 

# -FIL,
PM 10 

# -PRI, PM 2.5 

# -FIL, PM 2.5 

# -PRI, and/or PM-CON. From any one of these pollutants, EPA has developed augmentation procedures to estimate PM 10 

# -PRI, PM 10 

# -FIL, PM 2.5 

# -PRI, PM 2.5 

# -FIL, and PM-CON. If not included in a State/local inventory, PM 10 

# -PRI and PM 2.5 

# -PRI were calculated by adding PM 10 

# -FIL and PM-CON or PM 2.5 

# -FIL and PM-CON, respectively.

The procedures for augmenting point source PM emissions are documented in detail in Appendix C of Documentation for the Final 1999 National Emissions Inventory {Version 3} for
Criteria Air Pollutants a nd Ammonia – Point Sources , January 31, 2004). Briefly, the PM data augmentation procedure include s the following five steps:

 

# Step 1: Prepare S/L/T PM and PM 10 

# Emissions for Input to the PM Calculator

 

# Step 2: Develop and Apply Sour ce-Specific Conversion Factors

 

# Step 3: Prepare Factor s from PM Calculator

 

# Step 4: Develop and Apply Algorithms to Esti mate Emissions from S/L/T Inventory Data

 

# Step 5: Review Results and Update the NEI with Emission Estimates and Control Information.

Please refer to the EPA documentation for a co mplete description of the PM augmentation procedures.

Table 1.1-2 compares the original PM emission estimates from the S/L CERR submittals and the
revised 2002 VISTAS emissions estimates calcula ted using the above methodology. This table is intended to show that we took whatever States pr ovided in the way of PM and filled in gaps to
add in PM-CON where emissions were missing in order to calculate PM 10 

# -PRI and PM 2.5 

# -PRI for all processes to get a complete set of pa rticulate data. We did not compare any other pollutants besides PM, since for other pollutant s CERR emissions equal VISTAS emissions. As noted in Table 1.1-2, we made si gnificant revisions to the PM emissions for Kentucky in the Base F inventory and for South Ca rolina in the Base G inventory.

Note 1: CERR refers to data as submitted by S/L agencies; VI STAS refers to data calculated by MACTEC using the PM augmentation methodologies described in this document.
Note 2: KY DEP’s initial CERR submittal reported particulate matter emissions using only PM-PRI pollutant code. MACTEC used this pollutant code during the initial PM augmentation routine. In February 2005, KY DEP indicated that data reported usin g the PM-PRI code should actually have been reported using the PM 10 

## -PRI code. MACTEC performed a subsequent PM augmentation in April 2005 using the PM 10 

## -PRI code. These changes were reflected in the Base F emission inventory.

# After the PM augmentation process was performed, we executed a series of checks to identify potential inconsistencies in the PM inventory. These checks included:

 

# PM-PRI less than PM 10 

# -PRI, PM 2.5 

# -PRI, PM 10 

# -FIL, PM 2.5 

# -FIL, or PM-CON;

 

# PM-FIL less than PM 10

# -FIL;

 

# PM 10 

# -PRI less than PM 2.5 

# -PRI, PM 10 

# -FIL, PM 2.5 

# -FIL or PM-CON;

 

# PM 10 

# -FIL less than PM 2.5 

# -FIL;

 

# PM25-PRI less than PM 2.5 

# -FIL or PM-CON;

 

# The sum of PM 10 

# -FIL and PM-CON not equal to PM 10 

# -PRI; and

 

# The sum of PM 2.5 

# -FIL and PM-CON not equal to PM 2.5 

# -PRI. S/L agencies were asked to review this in formation and provide corrections where the inconsistencies were significant. In general, co rrections (or general directions) were provided in the case of the potential inconsistency issues. In other cases, the ag ency provided specific process level pollutant corrections.

Note that for the Base G inventory, only the PM 10 

# -PRI and PM 2.5 

# -PRI emission estimates were retained since they are the only two PM species that are included in the air quality modeling. Other PM species were removed from the Base G inventory to facilita te emissions modeling.

1.1.1.4 EGU Analysis
We made a comparison of the annual SO 2 

# and NO x 

# emissions for EGUs as reported in the S/L agencies CERR submittals and EPA’s Clean Air Markets Division (CAMD) CEM database to identify any outstanding discrepanc ies. Facilities report hourly CE M data to EPA for units that are subject to CEM reporti ng requirements of the NO x 

# State Implementation Plan (SIP) Call rule and Title IV of the Clean Air Act (CAA). EPA sums the hourly CEM emissions to the annual level, and we compared these annual CEM emi ssions to those in the S/L inventories. The 2002 CEM inventory containing NO x 

# and SO 2 

# emissions and heat input data were downloaded from the EPA CAMD web site ( www.epa.gov/airmarkets ).

The first step in the EGU analysis involved prep aring a crosswalk file to match facilities and units in the CAMD inventory to facilities and units in the S/L invent ories. In the CAMD inventory, the Office of Regulat ory Information Systems (ORIS) identification (ID) code identifies unique facilities and the unit ID identifies unique boilers and internal combustion engines (i.e., turbines and reci procating engines). In the S/L inventories, the State and county FIPS and State facility ID togeth er identify unique facilities and the emission unit ID identifies unique boilers or internal co mbustion engines. In most cases, there is a one-to-one correspondence between the CAMD id entifiers 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. We created an Excel spreadsheet that contained an initial crosswalk with the
ORIS ID and unit ID in the CEM inventor y matched to the Stat e and county Federal

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 16 

# Implementation Plan (FIPS), State facility ID, and emission unit ID in the S/L inventory. The
initial crosswalk contained both the annual emissi ons summed from the CAMD database as well
as the S/L emission estimate. It should be noted that the initial matc hing of the IDs in both inventories was based on previ ous crosswalks that had been developed for the preliminary VISTAS 2002 inventory and in-house info rmation compiled by MACTEC and Alpine Geophysics. The matching at the facility level was nearly complete. In some cases, however, S/L agency or stakeholder 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 pr epare an Excel spreadsheet that compared the annual emissions from the hourly CAMD inventor y to the annual emissions reported in the S/L inventory. The facility-level compar ison of CEM to emission inventory NO x 

# and SO 2 

# emissions found that for most facilities, the annual emissi ons from the S/L inventory equaled the CAMD CEM emissions. Minor differences could be explai ned because the facility in the S/L inventory contained additional small or emergency units th at were not included in the CAMD database.

The final step was to compare the SO 2 

# and NO x 

# emissions for select Southern Company units in the VISTAS region. Southern Company is a super-regional company that owns EGUs in four VISTAS States – Alabama, Florid a, 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 preliminar y VISTAS 2002 inventory. In most cases, these estimates were reviewed by the States and incorporated into the States CERR submittal. The exception to this was a decision made by Georgia’s Department of Environmental Protection (GDEP) to utilize CEM-based emissions for th e actual 2002 emissions inventory for sources within the State when Southern Company also provided data. There were no major
inconsistencies between the S outhern Company data, the CAMD data, and the S/L CERR data.

The minor inconsistencies included small diffe rences (<2 percent) in emission estimates, 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 i ndividually. We compared SO 2 

# and
NO x 

# emissions on a unit by unit basis and di d not find any major inconsistencies.

1.1.1.5 QA Review of Base F Inventory
QA checks were run on the Base F point source invent ory data set to ensure that all corrections provided by the S/L agencies and stakeholders were correctly incorporated into the S/L
inventories and that there were no remaining QA issues. After exporting the inventory to ASCII text files in NIF 3.0, the EPA QA program wa s run on the ASCII files and the QA output was reviewed to verify that all QA issues that could be addressed were resolved.

# Throughout the inventory developm ent process, QA steps were pe rformed to ensure that no double counting of emissions occurred, and to en sure that a full and complete inventory was developed for VISTAS. QA was an important com ponent to the inventory development process and MACTEC performed the following QA steps on the point source component of the VISTAS revised 2002 base year inventory:

1. Facility level emission summaries were pr epared and evaluated to ensure that emissions were consistent and th at there were no missing sources.

2. State-level EGU and non-E GU comparisons (by pollutant ) were developed between the Base F 2002 base year inventory, the draft VISTAS 2002 inventory, and the 1999 NEI Version 2 inventory.

3. Data product summaries and raw NIF 3.0 data files were provided to the VISTAS Emission Inventory Technical Advisor and to the Point Source, EGU, and non-EGU Special Interest Work Group representative s for review and comment. Changes based on these comments were reviewed and approve d by the S/L point source contact prior to implementing the changes in the files.

4. Version numbering was used for all i nventory files developed. The version numbering process used a decimal system to track major and minor changes. For example, a major change would result in a version going from Base F1 to Base F2.

1.1.1.6 Additional Base G Updates and Corrections
S/L agencies completed a detailed review of th e Base F inventory. Table 1.1-3 summarizes the updates and corrections to the Base F inventor y that were requested by S/L agencies and incorporated into the Base G inventory.

There was a discrepancy between the ba se year 2002 and 2009/2018 emissions for PM 10 

# -PRI,
PM 2.5 

# -PRI, and NH 3 

# . The 2002 emissions were provided dire ctly by the S/L agencies and were estimated using a variety of techniques (i.e., EP A emission factors, S/L emission factors, sitespecific emission factors, and source test da ta). The 2009/2018 emissions, on the other hand, were estimated by Pechan (see Section 2.1.1.3) usi ng an emission factor file based solely on AP-42 emission factors. An adjustme nt was made for 2002 EGU PM and NH 3 

# emissions to reconcile these differences. The post- processed Integrated Planning Model ® ( 

# IPM ® 

# ) 2009/2018 output uses a set of PM and NH 3 

# emission factors that are “t he most recent EPA approved
uncontrolled emission factors” – these are most likely not the same emission factors used by States and emission inventory pr eparation contractors for estimating these emissions in 2002 for EGUs in the VISTAS domain. VISTAS performe d a set of modifications to replace 2002 base year PM and NH 3 

# emission estimates with estimates deri ved from the most recent EPA-approved
emission factors. For further details of the me thodology used to make this adjustment, see EGU Emission Factors and Emission Factor Assignment, memorandum from Greg Stella to VISTAS
State Point Source Contacts and VISTAS EG U Special Interest Workgroup, June 13, 2005.

# Table 1.1-3 Summary of Updates and Corrections to the Base F 2002 Inventory Incorporated into the 2002 Base G Inventory.

Affected State(s) Nature of Update/Correction

TN, WV The latitude and longitude values for TN (except the four local programs) and WV were truncated to two decimal places in the Base F inventory. MACTEC re-exported the NIF ER tables in a manner that so that the latitude and longitude were not truncated in the Base G inventory.
AL Corrected the latitude and longitude for two facilities: Ergon Terminalling (Site ID: 01-073-010730167) and Southern Power Franklin (Site ID: 01-081-0036).
Corrections to stack parameters at 10 facilities for stacks with parameters that do not appear to fall into the ranges typically termed "acceptable" for AQ modeling.
FL Corrected emission values for the Miami Dade RRF facility (Site ID: 12-086-0250348).
GA Hercules Incorporated (12-051-05100005) had an errone ous process id (#3) within emission unit id SB9 and was deleted. This removes about 6,000 tons of SO 2 

### from the 2002 inventory.
Provided a revised file of location coordinates at the stack level that was used to replace the location coordinated in the ER file.
NC Made several changes to Base F inventory to correct the following errors: 1. Corrected emissions at Hooker Furniture (S ite ID: 37-081-08100910), release point G-29, 9211.38 tons volatile organic compounds (VOC's) should be 212.2 tons, 529.58 tons PM 10 

### should be 17.02 tons, 529.58 tons PM2.5 should be 15.79 tons in 2002 inventory. 2. Identified many stack parameters in the ER file that were unrealistic. Several have zero for height, diameter, gas velocity, and flow rate. NC used th e procedures outlined in Section 8 of the document ""National Emission Inventory QA and Augmentation Report" to correct unrealistic stack parameters. 3. Identified truncated latitude and longitude values in Base F inventory. NC updated all Title V facility latitude and longitude that was submitted to EPA for those facilities in 2004. Smaller facilities with only two decimal places were not corrected. 4. Corrected emissions for International Paper (3709700045) Emission Unit ID, G-12, should be 1.8844 tons VOCs instead of 2819.19 tons in 2002
SC Corrected PM species emission values. SC DHEC’s initial CERR submittal reported particulate matter emissions using the PM-FIL, PM 10 

### -FIL, and PM25-FIL pollutant c odes. In August 2005, SC DHEC indicated that data reported using the PM-FIL, PM 10 

### -FIL, and PM25-FIL pollutant codes should actually have been reported using the PM-PRI, PM 10 

### -PRI, and PM25_PRI codes. MACTEC performed a subsequent PM augmentation in April 2006 using the revised pollutant codes. These changes were reflected in the Base G emission inventory.
TN Identified six facilities that closed in 2000/2001 but had non-zero emissions in the 2002 Base F inventory. MACTEC changed emissions to zero for all pollutants in the Base G 2002 inventory.
Supplied updated emission inventory for the Bowater facility (47-107-0012) based on the facility’s updated 2002 emission inventory update.
Replaced data from Hamilton County, Tennessee, us ing data from Hamilton County’s CERR submittal as contained in EPA’s 2002 NEI (in Base F, the inventory for Hamilton County was based on the draft VISTAS 2002 inventory, which in turn was based on the 1999 NEI).
Updated emissions for PCS Nitrogen Fertilizer LP (Site ID: 47-157-00146)
WV Updated emissions for Steel of West Virginia (Site ID: 54-011-0009)

Made changes to several Site ID names due to changes in ownership
Made corrections to latitude/longitude and stack parameters at a few facilities for stacks with parameters that do not appear to fall into the ranges typically termed "acceptable" for AQ modeling.

# 1.1.1.7 Summary of B&F 2002 Inventory
Tables 1.1-4 through 1.1-10 summarize the B&F 2002 base year inventory. All values are in tons. Note that no changes to the Base G 2002 poi nt source inventory were made during the Base G2 and B&F update cycles (in other words, Base G = Base G2 = B&F). Note also that Alabama suggested additional changes to the 2002 inventory resulting from their PM 2.5 

# modeling for the Birmingham area; however, these ch anges were identified too late to be incorporated in the VISTAS B&F inventory and ASIP modeling.

For the purposes of Tables 1.1-4 through 1.1-10, E GU emissions include the emissions from all processes with a Source Classifi cation 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 ar e included in the non-EGU column. Note that aggregating emissions into EGU and non-EGU s ectors based on the above SCCs causes a minor inconsistency with the EGU emissions reported in EPA’s CAMD database. The EGU emissions summarized in these tables may include emissions from some smaller electric generating units in the VISTAS inventory that are not in CAMD ’s 2002 CEM database or the IPM forecasted
emissions. The minor inconsistencies result in a less than 2 percent difference between the summary tables below and the da ta from CAMD’s CEM database.

# 1.1.2 Development of Typical Year EGU inventory
VISTAS developed a typical y ear 2002 emission inventory for EGUs to avoid anomalies in emissions due to variability in meteorology, eco nomic, and outage factors in 2002. The typical year inventory represents the five year ( 2000-2004) period and was used to determine the regional haze reasonable progress goals. Actual 2002 emissions were used when comparing the CMAQ modeling results to the 2002 measurements in the model performance evaluation. A
detailed discussion of how the actual and typical year EGU inve ntories were used for modeling
is contained in the Technical Support Document for VISTAS Emissions and Air Quality Modeling to Support Regional Haze State Implementation Plans located on the VISTAS web site ( http://www.vist as-sesarm.org )

Data from EPA’s CAMD were used to de velop normalization fact ors for producing a 2002 typical year inventory for EGUs . We used the ratio of the 2000-2004 average heat input and the 2002 actual heat input to normalize the 2002 actua l emissions. MACTEC obtained data from EPA’s CAMD for utilities regulated by the Acid Rain program. Annual data for the period 2000 to 2004 were obtained from the CAMD web site ( www.epa.gov/airmarkets ). The parameters
available were the SO 2 

# and NO x 

# emission rates, heat input, a nd operating hours. We used the actual 2002 heat input and the av erage 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 he at input was calculated for the one or two years in which the unit did operate. For example, if the unit operated only during 2002, then the normalization factor w ould be 1.0. The annual actual emissions were multiplied by the normalization factor to dete rmine the typical emissions for 2002, as follows:

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 prio r to 2002, then we used zero emissions for the typical year. If the unit had not been permanently retired and would normally operate in a typical year, then we used the 2001 (or 2000) heat input and emission rate to calculate th e typical year
emissions.

The Southern Company provided ty pical year data for their sour ces. Hourly emissions data for criteria pollutants were provide d. MACTEC aggregated the hourly emissions into annual values. Further documentation of how Southern Company created the typical year inventory for their

# -PRI. The Southern Company typical year data were used for Southern Company sources in Alabama, Florida, and Mississippi. Georgia EPD elected to use the typical year normalization factor
derived from the CAMD data instead of the Southe rn Company typical year data (as was used in the Base F inventory).

The final step was to replace the 2002 actual emi ssions with the 2002 typical year data described above. MACTEC provided the raw data and resu lts of the typical y ear calculations in a spreadsheet for S/L agency review and comment. Any comments made were incorporated into the Base G inventory.

# 1.2 Area Sources

This section details the development of the Ba se G 2002 base year inventory for area sources. There are three major components of the area source sector of the inventory. The first component is the “typical” year fire inve ntory. Version 3.1 of the VISTAS ba se year fire inventory provided
actual 2002 emissions estimates. Since fire emissions are not easily grown or projected, in order to effectively represent fires in both the base and future year inventories, VISTAS determined that a typical year fire inventory was necessary. Development of th e “typical” year fire inventory covered wildfire, prescribed burni ng, agricultural fires and land cl earing fires. The first part of this section of the report disc usses the development of the ty pical year fire inventory. The methodology provided in that sectio n is identical to the documentation provided for Base F since the “typical” year inventory was developed as part of the Base F development effort. The major change in Base G for the fire component of the inventory was the development of projection year inventories that represent alternatives to th e “typical” year inventory. These alternative projections incorporated projec ted changes in the acreage burned for prescribed fires on Federal lands. These projections are an augmen tation of the “typical” year inventory.

The second component of the area source inventor y was the incorporation of data submitted by
the VISTAS States to the United States Environm ental Protection Agency (EPA) as part of the CERR. Work on incorporating the CERR data into the revised base year involved: 1) obtaining the data from EPA, 2) evaluating the emissions and pollutants reported in order to avoid double counting and 3) backfilling from the existing VISTAS 2002 base year inventory for missing sources/pollutants. The processes used to perf orm those operations are described in the second portion of this section. That work was performed as part of the Base F inventory effort. In general no changes to that method were made as part of the Base G inventory updates. The methods used for the Base F inventory development effort using the CERR submittals have been maintained in this document. Where necessary, additional documentation has been added to 1) reflect changes that resulted from VISTAS St ates review of the Base F inventory and the incorporation of those changes into Base G, 2) changes made to how certain sources were estimated or 3) addition of new sources not found in Base F.

The final component of the area source invent ory was related to the development of NH 3 

# emission estimates for livestock and fertiliz ers and paved road PM emissions. For the NH 3 

# emission estimates for livestock and fertilizer s we used version 3.6 of the Carnegie Mellon University (CMU) NH 3 

# model. For the paved road PM emissions, we used the most recent estimates developed by EPA as part of the National Emission Inventory (NEI) development effort. EPA had developed an improved method ology for estimating paved road emissions so
those values were substituted dir ectly into the inventory after receiving consensus from all of the VISTAS States to perform the replacement. Deta ils on these methods are provided in the third

# portion of this section of the docum ent. That section is virtually identical to that from the Base F inventory document as there were only a c ouple of changes to the ammonia portion of the inventory and some updates to all fugitive dus t categories including paved roads on a global
basis between Base F and Base G.

Finally, quality assurance steps for each component of the area source inventory are discussed.

1.2.1 Development of a “typical” year fire inventory
Typical year fire emissions were developed st arting from the actual fire acreage data and
emission calculated for each VISTAS State. Th e table below shows the data submitted by each State in the VISTAS region indicating what data was received from each State for the purposes of calculating actua l fire emissions.

Ag Burning 9 9 9 9

In order to effectively characterize fire emissions in the VI STAS region, a typical (as opposed to strictly 2002 year based inventory) was required. Development of a typica l year fire inventory provided the capability of using a comparable data set for both the base year and future years.
Thus fire emissions would remain the same for air quality and visibili ty modeling in both the base and any future years. MACTEC originally proposed five different methods for developing the typical fire year to the VISTAS Fire Sp ecial Interest Work Group (SIWG) and requested their feedback and preference fo r developing the final typical y ear inventory. The method that was selected by SIWG members was to use a met hod similar to that used to develop an early version of a 2018 projection invent ory. For that early 2018 inventor y, 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. For Base F and G, the decision of th e VISTAS Fire SIWG was to base the ratio on county level data for States that supplied long term fire-by-fire acreage data rather than Statelevel ratios. Where States did not supply long term fire-by-fire acreage data, MACTEC reverted to using State-level ratios. With one broad ex ception (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

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 27 

# 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.

Thus if we had long term county prescribed fire data from a State, we developed a county acreage ratio of:

acreageRx levelcounty actual 2002 acresRx levelcounty average termLong

= 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 th e ratio was then used with the fuel loading and
emission factor values that we already had (and had been revi ewed by the SIWG) to calculate emissions using the same method used for th e 2002 actual values (whi ch were previously documented). The following lists indicate which c ounties used the State ratios by fire type.

# There were three exceptions to this method.

Exception 1: Use of State Ratios for Wildfires

The first exception was that wildfires estimates were developed using State ratios rather than county ratios. This change was made after initial quality assurance of the draft estimates revealed that some counties were showing unrealistic values created by very short term data records or missing data that created unrealistic ratios. In addition, exceptionally large and small fires were removed from the database since they were felt to be atypical. For example the Blackjack Complex fire in Georgia was removed from the dataset because the number of acres burned was “atypical” in that fire. We also removed all fires less than 0.1 acres from the dataset.

Exception 2: Correction for Blackened Acres on Forest Service Lands

Following discussions with the United States Fo rest Service (Forest Se rvice) (memo from Cindy Huber and Bill Jackson, dated August 13, 2004), it was determined that the acres submitted by the Forest Service for wildfires and prescribed fires represented perimeter acres rather than “blackened” acres. Thus for wildfires and prescr ibed fires on Forest Service lands, a further correction was implemented to correct the peri meter acre values to blackened acres. The
correction was made based on the size of the fire . For prescribed fires over 100 acres in size the acreage was adjusted to be 80 per cent of the initial re ported value. For pres cribed fires of 100 acres or less the acreage values were maintained as reported. For wildfire s, all reported acreage values were adjusted to be 66 percent of their initially reported values. These changes were made to all values reported for Fo rest Service managed lands.

Exception 3: Missi ng/Non-reported data

When we 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. For example, if no agricultural burning long te rm acreage data was reported for a particular State, MACTEC determined an overall VISTAS re gional average ratio that was used to multiply

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 29 

# times the 2002 values to produce th e “typical” values. This techni que was applied to all fire types when data was missing.

In addition, for wildfires and prescribed burning, ratios were developed for “northern” and “southern” tier States within the VISTAS region a nd those ratios were app lied to each State with missing data depending upon whether they were consid ered a “northern” or “southern” tier State. Development of “southern” and “nor thern” tier data was an attempt to account for a change from a predominantly pine/evergreen ecosystem (southern) to a pine/deciduous ecosystem (northern).
States classified as “southern” included: AL , FL, GA, MS, and SC. St ates classified as
“northern” included: KY , NC, TN, VA, and WV.

Finally for land clearing and agri cultural fires, there are no NH 3 

# and SO 2 

# emissions. This is due
to the lack of emission factors for th ese pollutants for these fire types.

Table 1.2-1 shows fire emissions from the orig inal base year emissi on inventory (VISTAS 3.1),
the actual 2002 emissions and th e typical year emissions for the entire VISTAS region. The actual 2002 and typical fire emissions represen t the Base F and Base G 2002 emissions. The typical emissions also represent the 2009 and 2018 emissions for all fire types with the exception of prescribed burning. Revisions made to the typi cal year prescribed fi re emissions for 2009 and 2018 are detailed in the projection section. Also, State level Base G emissions from fires for all years can be found in the tables in Appendix A. Values for fires in thos e tables are “typical” year values.

Figures 1.2-1 through 1.2-4 show the State by Stat e changes in emissions between the original 2002 base year fire inventorie s, the actual 2002 and the typical year inventories for carbon monoxide (CO) by fire type.

# 1.2.2 Development of non-fire inventory
The second task in preparing the area source co mponent of the Base F and Base G 2002 base year inventory was the incorporation of data submitted by the VISTAS States to the EPA as part of the CERR. With few exceptions, Base F and Ba se G inventories for this component of the inventory are identical. Modi fications to the Base F met hodology (described below) only
resulted from modifications from the VISTAS States during review of the Base F inventory. The changes made to the inventory based on these revi ews are described in the last portion of this section of the report. The information presented below describes the method used to incorporate CERR data as part of Base F.

Work on incorporating the CERR data into the 2 002 Base F inventory invo lved: 1) obtaining the data from EPA, 2) evaluating the emissions and pollutants reported in order to avoid double counting and 3) backfilling from the earlier vers ion of the VISTAS 2002 base year inventory for missing sources/pollutants. The processes used to perform those operations are described below. This work did not include any of the fire emi ssion estimates described above. In addition it did not include emission estimates for ammonia from ag ricultural and fertilizer sources. Finally it did not include PM emissions from paved roads. Each of those categories was estimated separately.

Data on the CERR submittals was obtained from EPA’s Draft NEI download file transfer protocol (FTP) site where the data are stored af ter they’ve been processed for review. The data submitted in National Emission Inventory Format (NIF) was downloaded from that site. Once all of the files were obtained, MACTEC ran the files through the EPA NIF Format and Content checking tool to ensure that the files were submi tted in standard NIF format and that there were no issues with those files. In a couple of cases small errors were found. Fo r example, in one case a county FIPs code that was no longer in us e was found. MACTEC contacted each VISTAS State area source contact person to resolve the issu es with the files and corrections were made.
Once all corrections to the native files we re completed, MACTEC continued with the incorporation of the data into the VISTAS area source files.

Our general assumption was that unless we determined otherwise, the CERR submittals represented full and complete inventories. Wh ere a State submitted a complete inventory, our plan was to simply delete the previous 2002 base year data and replace it with the CERR submittal. Prior to this replacement however, we stripped out the following emissions:

1. All wildfire, prescribed burning, land cl earing and agricultural burning emissions submitted to EPA by the States as part of the CERR process were removed since they were to be replaced with emissions estim ated using methods described earlier.
2. All fertilizer and agricult ural ammonia emission records submitted to EPA by the States as part of the CERR process were removed. These were replaced with the estimates developed using the CMU Ammonia model.

# 3. All emissions from paved roads submitted to EPA by the States as part of the CERR process were removed. These emissions were replaced with updated emissions developed by U.S. EPA as part of their 2002 NEI development effort.
This approach was used for most State and Local emission submittals to prepare the Base F inventory. There were a few cases where alternat ive data were used to prepare the Base F inventory. In general, these alternatives involved submittal of alternative files to the CERR data by S/L agencies. Table 1.2-2 below summarizes the data used to prepare the Base F inventory. In general the data were derived fr om one of the following sources:
1. CERR submittal obtained from EPA FTP s ite as directed by VISTAS States;
2. State submitted file (either revised from CERR submittal or separate format);
3. VISTAS original 2002 base year (VISTA S version 3.1 base year file); or
4. EPA’s preliminary 2002 NEI.

# In order to track the sources of data in the final Base F and Base G NIF files, a field was added to the NIF format files developed for VISTAS to track each data source. A field named Data_Source was added to the EM ta ble. A series of codes were a dded to this field to mark the
source of each emissions value in the Base F and Base G inventories. Valu es in this field are
detailed in Table 1.2-3.

# Most States submitted complete inventories for Ba se F. Virginia’s inventory required a two stage update. Virginia’s CERR submittal only containe d ozone precursor pollutants (including CO). For Virginia, MACTEC’s original plan was to maintain the previous 2002 VISTAS base year emissions for non-ozone pollutants and then do a simple replacement for ozone pollutants. However during the QA phase of the work, MACTEC discovered that there were categories that had ozone precursor or CO emissions in the subm ittal that weren’t in the original 2002 VISTAS base year inventory that should have PM or SO 2 

# emissions. For those records, MACTEC used an

# emissions ratio to build records for emissions of these pollutants. Data for Virginia PM and SO 2 

# emissions were generated by de veloping SCC level ratios to NO x 

# from the VISTAS 2002 base year inventory (version 3.1) or from emission f actors and then calculati ng the emissions based on
that ratio.

1.2.3 2002 Base G inventory updates
After the Base F inventory was submitted and us ed for modeling, VISTAS States were provided an opportunity for further review and comment on the Base F inventory. As a result of this review and comment period, several VISTAS States provided revisions to the Base F inventory.

In addition to and as an outgrowth of some of the comments provided by the States during the review process, some of the changes made to th e inventory were made globally across the entire VISTAS region. This section discusses the specif ic State changes followed by the global changes made to the area source component of the inventory for all VISTAS States.

1.2.3.1 Changes resulting from State review and comment

Alabama

Alabama suggested several changes and had questi ons concerning a few categories in the Base F inventory. The changes/questions were:

1. For Source Classification Code (SCC) 2102005000 (Industrial Boilers: Residual Oil) and SCC 2103007000 (Instit utional/Commercial Heating: Liquefied Petroleum Gas) the Alabam a noted that the Base F VISTAS inventory had values for NO x 

# , VOC and CO for the State, but no values for
SO 2 

# , PM 10 

# or PM 2.5


# . MACTEC evaluated this information and found that there were actually emissions for two
counties in AL for that SCC that had either SO 2 

# and/or PM emissions. The data used to develop the 2002 Base F inventory for AL came from th e preliminary 2002 CERR submittals (see above)
which should have included SO 2 

# and PM but did not except fo r two counties. According to MACTEC’s protocol for use of these files, the files received from EPA were to be used “as is” unless the States provided comments during th e Base F comment period to correct the CERR
submittal. No comments were received from AL on the CERR submittal used for Base F. For 2002 Base G, AL provided an updated database file for these SCCs for all counties in the State that provided revised values for emissions and included SO 2 

# and PM. The revised file was used to update the Base F data for Base G.

2. AL noted that the Base F inve ntory included SCC 2401002000 (Solvent Utilization, Surface Coating, Architectural Coatings - Solvent-based, Total: All Solvent Types) and 2401003000 (Solve nt Utilization, Surface Coating,

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 39 

# Architectural Coatings - Water-based, To tal: All Solvent Types) as well as SCC 2401001000 (Solvent Utilization, Surface Coating, Architectural Coatings, Total: All Solvent Types). This resulted in double counting of the emissions for this category. AL sugge sted removal of the breakdown SCCs
and use of the total SCC.

MACTEC deleted records for the breakdown SC Cs and retained the total all solvents
SCC emissions.

3. AL found the SCCs listed below missing from the Base F VISTAS inventory.

SCC VOC
Emissions SCC Description 2401025000 1139.91 Surface Coatings: Metal Furniture, all coating types 2401030000 425.27 Surface Coatings: Paper, all coating types 2401065000 344.08 Surface Coatings: Electronic a nd Other Electrical, all coating
types 2430000000 504.29 Solvent Utilization, Rubber/Plasti cs, All Processes, Total: All Solvent Types 2440020000 3043.78 Solvent Utilization, Miscellaneous Industrial, Adhesive (Industrial) Application, Total: All Solvent Types
Total for AL 5457.32

MACTEC found that the emissions for these SCCs were included in the Base F inventory, but with slightly different total emissions. AL pr ovided an updated county-level emissions file for use in updating the Base G inventory. That file was used to update the NIF records for AL for
those SCCs.

4. AL noted that emissions in the Ba se F inventory were found for SCC 2465000000 and SCCs 2465100000, 2465200000, 2465400000, 2465600000, and 2465800000. These last five SCCs represent a subset of the emissions in the 246500000 SCC resulting in potentia l double counting of emissions.

MACTEC deleted all emissions associated with the Total SCC 2465000000 and retained the subset SCCs for the Base G inventory.

Florida
Florida provided comments indicating that they felt that emissions from the following sources and counties were too high, especially fo r CO and PM and were likely zero:

## 40 

#  motor vehicle fire - Palm Beach County

 woodstoves - Miami Dade, Hillsborough, Orange , Polk, Ft Myers, Pasco and Sarasota
Counties

 fireplaces - Miami Dade and Hillsborough Counties

Emissions from these sources in the counties specified were se t to zero by MACTEC for the Base G inventory.

North Carolina
North Carolina provided corrected emission files for 2002 Base F. A text file with emission values was provided and used to update the Base F emissions to Base G. The updated emissions were applied directly to the Base F NIF file. The file provided was similar to the “EM” NIF table. An update query was used to update the data supplied in the text file to the Access
database NIF file. All ch anges were implemented.

South Carolina
South Carolina had two issues concerning the Ba se F inventory. These issues related to 1)
additional SCCs that were in BASE F 2009 and 2018, but not in 2002 Base F and 2) SCCs that were in the U.S. EPA 2002 NEI inventory, bu t not in the VISTAS 2002, 2009, or 2018 Base F inventory.

MACTEC investigated the additional SCCs f ound in 2009 and 2018 Base F and found that the SCCs actually were not missing in the 2002 Base F inventory but only had emissions for PM.
Thus the emissions were maintained as they were provided in Base F.

With respect to the SCCs that were found in the U.S. EPA 2002 NEI, MACTEC investigated and found that they were not included in the Base F in ventory because they were not included in the 2002 CERR submittal used to produce the Base F updates. The SCCs were apparently added by EPA later in the NEI development process. In addition, MACTEC also evaluated whether or not
the SCCs were found in other VISTAS States Base F inventories. MACTEC found that some States included them and some did not, there was no consistency betwee n the States. MACTEC also found that typically emissions for these SCCs were low in emissions, generally with emissions of only a few tons to tens of tons pe r year. The decision was made with South Carolina
concurrence not to add these SCCs to the Base G inventory. These SCCs were: 210205000, 2102011000, 2103007000, 2103011000, 2104007000, 2104011000, 2302002100, 2302002200, 2302003100, 2302003200, 2610000500, 2810001000, and 281001500.

# Virginia
Virginia provided an updated 2002 base year emissi ons file. The data in that file were used to update the Base F inventory emission values to t hose for Base G. In addition, Virginia provided information on several source catego ries that required controls fo r future year projections since
the sources were located in countie s/cities in northern Virginia a nd were subject to future year Ozone Transport Commission (OTC ) regulations. MACTEC added in the base year control levels to the Base G inventory file for these cate gories so that they coul d be estimated correctly in future years. The controls added were fo r mobile equipment repair/refinishing sources, architectural and industrial maintenance coating sources, consumer products sources, and solvent metal cleaning sources. Minor errors were found in some entries for the initial file provided and VA provided a revised file with corrections and minor additions.

Jefferson County, KY

In December 2007, KY Division of Air Quality st aff identified that Jefferson County, KY was showing zero area source SO 2 

# emissions. MACTEC was asked to investigate why there were zero emissions. MACTEC’s investigation show ed that some of the surrounding counties had
area source SO 2 

# emissions, but that Jeffe rson County’s were indeed zero. MACTEC determined that there were emissions in pre-Base F invent ories which would have originated from the 1999 NEI grown to 2002. However under our Base F update procedure, we obtained a CERR submittal from Jefferson County. That file contained only emissions for Jefferson County including a limited number of non-ozone polluta nt records. Thus under our procedure for processing CERR submittals (see above), the file wa s considered to be full and complete for purposes of inclusion in the Base F inventory and wa s processed as if it c ontained more than just ozone pollutant records (i.e., s upplemental pollutant records were not required). The file provided, however did not have any SO 2 

# records. The lack of area source SO 2 

# emissions was not discovered during the normal State/local revi ew process or during MACTEC’s QA process performed on the initial version of the Base F inventory and was thus carried forward into the Base G2 (and thus the Best and Final) inve ntory and modeling effort where it remained
undiscovered until December 2007.

After discovery of the lack of SO 2 

# records, MACTEC recovered the SO 2 

# (and some PM) records from the pre-Base F inventories and pr epared updated records for 2002, 2009 and 2018. However, because of the timing of the release of these data (December 2007) and the fact that
VISTAS could not rerun 2002 and 2009 in time for the final modeling needs with these data, these changes were not included in the final f iles (Base G2/Best and Final). Therefore, the summaries provided in this document do not reflec t those emissions, nor do the Best and Final inventory files include them.

# 1.2.4 Ammonia and paved road emissions
The final component of the Base F inve ntory development was estimation of NH 3 

# emission
estimates for livestock and fertilizers and paved road PM emissions. For the NH 3 

# emission
estimates for livestock and fertilizer s we used version 3.6 of the CMU NH 3 

# model ( http://www.cmu.edu/ammonia/ ). Results from this model were used for all VISTAS States. The
CMU model version 3.6 was used in large part because it had been just recently been updated to include the latest (2002) Census of Agriculture animal population st atistics. Prior to inclusion of the CMU model estimates, MACTEC removed any a mmonia records for agricultural livestock or
fertilizer emissions from the VISTAS 2002 initia l base year inventory. MACTEC also generated emissions from human perspiration and from wildlife using the CMU model and added those
emissions for each State.

For the Base G ammonia inventory, MACTEC removed all wildlife and human perspiration
emissions. VISTAS decided to remove these em issions from the inventory. Human perspiration was dropped due to a discrepancy in the units used for the emission factor that was not resolved prior to preparing the estimate s and wildlife was dropped because VISTAS felt the activity data
was too uncertain. Thus all emi ssions from these two categories were deleted in the Base G 2002 inventory.

For the paved road PM Base F emissions, we us ed the most recent estimates developed by EPA as part of the NEI development effort (Roy Huntley, U.S. EPA, email communication, 8/30/2004). EPA had developed an improved methodology for estima ting paved road emissions
for 2002 and had used that method to calculate emissions for that source category. MACTEC
obtained those emissions from EPA and those values were substituted directly into the inventory after receiving consensus from all of the VISTAS States to perform the replacement. These files
were obtained in March of 2005 in NIF format from the EPA FTP site.

For the Base G emissions, modifications were ma de to the emissions estimates based on changes suggested by work of the Western Regional Air Partnership and U.S. EPA. Details of these changes are provided below in the section on gl obal changes made as part of the Base G inventory updates.

1.2.5 Global Changes Made for Base G
There were three global changes made between the Base F and the Base G inventory (beyond the
removal of wildlife a nd human perspiration NH 3 

# emissions). These changes were:

1. Removal of Stage II emissions from the area s ource inventory and inclusion in the mobile sector of the inventory,

2. Adjustment of fugitive dust PM 2.5 

# emissions, and

MACTEC, Inc. 

## 43 

# 3. Addition of emissions from portable fuel containers.

As part of the Base F review process, several VISTAS States had expressed surprise that the Stage II refueling emission estimates were in the area source component of the inventory. This decision had been made with SIWG agreement early on in the inventory development process because 1) some States had included it in thei r CERR submittals and 2) because the non-road and on-road mobile estimates had differing activity f actor units and could not be easily combined. However for Base G, the VISTAS States all agreed, especially in light of the different ways in which the emissions were reported in the CERR, to remove the Stage II refueling emissions from the area source inventory and include them in the non-road and on-road sect ors. Thus all records related to Stage II refueling were removed from the area source component of the Base G inventory.

PM 2.5 

# emissions from several fugitive dust sources were also updated for Base G. The Western Regional Air Partnership (WRAP) and U.S. EPA had been investigating overestimation of the
PM 2.5 

# / PM 10 

# ratio in several fugitive dust categories a nd U.S. EPA was in the process of making
revisions to AP-42 for several categories during preparation of the Base G inventory. Based on data received from U.S. EPA, VISTAS decided to revise the PM 2.5 

# emissions from construction, paved roads and unpaved road sources. PM 2.5 

# emissions in Base F were multiplied by 0.67, 0.6, and 0.67 for construction, paved roads and unpave d roads respectively to produce the values found in Base G. No changes were made to PM 10 

# , only to PM 2.5


# . Finally, as part of Virginia’s comments on the Base F inventory, emissions from portable fuel containers were mentioned as being absent from the inventory. MACTEC was tasked with developing a methodology that could be used to a dd these emissions to the Base G area source inventory. In investigating options for a met hod of estimating emissions, MACTEC found that the U.S. EPA had prepared a national invent ory of emissions by St ate for portable fuel
containers. Data on emissions from this sour ce prepared by U.S. EPA were presented in, “Estimating Emissions Associated with Portable Fu el Containers (PFCs), Dr aft Report, Office of Transportation and Air Quality, United States Environmenta l Protection Agency, Report # EPA420-D-06-003, February 2006”.

State-level emission estimates for 2005 derive d from Appendix Table B-2 of the PFCs report were used as the starting point for developi ng 2002 county-level emi ssions estimates. State emissions were derived from that table by using al l of the emission estimates in that table with the exception of values for vapor displacement and spillage from refueling operations. Those components of the State emissions were left out of the State-level emissions to avoid double counting refueling emissions in the non-road se ctor. For the purposes of 2002 emission estimates for Base G, the 2005 values were assumed equal to 2002 values.

## 44 

# The 2005 State-level estimates minus the refuelin g component from Appendix Table B-2 of the report were summed for each State and then allo cated to the county-level. The county-level allocation was based on the fuel usage info rmation obtained from th e NONROAD 2005 model runs conducted as part of the Base G inventory development effort (see the 2002 base year Base G non-road section below). MACTEC used th e spillage file from the NONROAD model (normally located in the DATA\EMSFAC directory in a standard installation of NONROAD) to
determine the SCCs that used containers for refu eling. The spillage file contains information by SCC and horsepower indicating whet her or not the refueling occurs using a container or a pump. All SCC and horsepower classes using containers were extracted from the file and crossreferenced with the fuel usage by county for those SCC/horsepower combinations from the appropriate year model runs (2002, 2009 or 2018). Then the fuel usages by county from the NONROAD 2005 runs prepared for VISTAS we re summed for those SCCs by county. The county level fuel use was then divided by the State total fuel use for the sa me SCCs to determine the fraction of total State fuel usage and that fraction was used to allocate the State-level emissions to the county.

1.2.6 Quality Assurance steps
Throughout the inventory developm ent process, quality assuran ce steps were performed to ensure that no double counting of emissions occurred, and to ensu re that a full and complete inventory was developed for VISTAS. Quality assurance was an important component to the inventory development process and MACTEC performed the following QA steps on the area source component of the 2002 Base F inventory:

1. All CERR and NIF format State supplied data submittals were run through EPA’s Format and Content checking software.

2. SCC level emission summaries were prepared and evaluated to ensure that emissions
were consistent and that th ere were no missing sources.

3. Tier comparisons (by pollutant) were deve loped between the revised 2002 base year inventory and the previous (ver sion 3.1) base year inventory.

4. Fields were either added or used within each NIF data table to track the sources of
data for each emission record.

5. Data product summaries were provided to both the VISTAS Emission Inventory
Technical Advisor and to Area Source and Fi res SIWG representatives for review and comment. Changes based on these comments were implemented in the files.

6. Version numbering was used for all i nventory files developed. The version numbering process used a decimal system to track major and minor changes. For

# example, a major change would result in a version going from 1.0 to 2.0. A minor change would cause a version number to go from 1.0 to 1.1. Minor changes resulting from largely editorial changes would result in a change from 1.00 to 1.01.

In addition, for the fires invent ory, data related to fuel loading and fuel consumption was reviewed and approved by the VISTAS Fire SIWG to ensure that values used for each type of
fire and each individual fire were appropriate. Members of th e VISTAS Fire SIWG included representatives from most State Divisions of Forestry (or equiva lent) as well as U.S. Forest Service and National Park Service personnel.

For Base G, similar QA steps to those outlined above for Base F were undertaken. In addition, all final NIF files were checked using the EPA Form at and Content checking software and summary information by State and pollutant were prepared comparing the Base F and Base G inventories.

1.3 Mobile Sources

This section describes the revisions made to the initial 2002 VISTAS Base Year emission inventory on-road mobile source input files. For this work actual emission estimates were not made, rather data files consistent with Mobile Emissions Estimation Model Version 6 (MOBILE6) were developed and provided to the VISTAS modeling contract or. These input data files were then run during the VISTAS modeling to generate on-road mobile source emissions using episodic and meteorological specific conditions configured in the sparse matrix operator Kernel Emissions modeling system (SMOKE) emissions processor.

During initial discussions with the VISTAS Mobile Source SIWG, some States indicated a desire
to use CERR mobile source emissions data in place of the VISTAS 2002 inventories generated by E.H. Pechan and Associates, Inc. (the init ial VISTAS 2002 Base Year inventory files).

However, the CERR emissions data by itself were not sufficient for an inventory process that includes both base and future year inventories. MACTEC needed to be able to replicate the CERR data rather than simply obtain CERR emissions estimates. The reason for this is that only input files were being prepared to provide revised 2002 estimates during the VISTAS modeling process, rather than the actual emission estimat es and that the 2002 input data files would be used as a starting point for the projected emission estimates. This meant that the appropriate vehicle miles traveled (VMT), MOBILE6, and/ or NONROAD model input data needed to be provided. If these data were pr ovided with the CERR emissions estimates we used it as the starting point for revision of the 2002 Base Y ear inventory. However MACTEC did not have
access to the on-road mobile CERR submissions from EPA, so re-submittal of these data directly to MACTEC was requested in order to begi n compiling the appropria te input file data.

## 46 

# In those cases where States did not provide CE RR on-road mobile source input data files, our default approach was to maintain the data inpu t files and VMT estimates for the initial 2002 Base Year inventory prepared by Pechan.

1.3.1 Development of on-road mobile sour ce input files and VMT estimates
Development of the 2002 on-road input files and VMT was a multi-step process depending upon
what the State mobile source contacts instructed us to use as their data. Information provided below provides incremental revisions made to on -road mobile source inventories or inputs in series from one inventory version to the next. In general the pro cess involved one of three steps from the original 2002 on-road mobile source data.

Base F Revisions

1. The first step was to evaluate the init ial 2002 base year files and make any nonsubstantive changes (i.e., changes only to confirm that the files posted for 2002 by
Pechan were executable and that all the neces sary external files n eeded to run MOBILE6 were present). This approach was taken for AL, FL, GA, MS, SC, and WV. For these
States the determination was made that th e previous files would be okay to use as originally prepared. For SC, the VMT file was updated, but that did not affect the MOBILE6 input files.

2. For other States, modification to the input files was required. The information below indicates what changes were made fo r other States in the VISTAS region.

KY – For Kentucky, the Inspection and Maintenance (I/M) records in the i nput files for Jefferson County were updated in order to better reflect the actual I/M program in the Louisville metropolitan area.

NC - Substantial revisions were implemented to th ese input files based on input from the State. The modifications necessary to reflect the desires of the State led to comp lete replacement of the previous input files. Among the changes made were:

 The regrouping of counties (including the movement of some counties from one county group to another and the creation of new i nput files for previously grouped counties). There were originally 32 input files; after the ch anges there were 49. The pointer file was corrected to reflect these changes.

 Travel speeds were updated in over 3000 scenarios.

 All I/M records were updated.

 All registration distributions were updated.

MACTEC, Inc. 

## 47 

#  I/M VMT fractions were updated (which only affected the pointer file).

 VMT estimates were updated (which has no di rect effect on the MOBILE6 input files but does ultimately affect emissions).

3. VA and TN – For these States, new input files were provided due to substantive changes
that the State wanted to make relative to the 2002 initial base year i nput files. In addition, revised VMT data were developed for each State.

Base G Revisions
For the production of the VISTAS 2002 Base G i nventory, VISTAS states reviewed the Base F inputs, and provided corrections, updates and supplemental data.

For all states modeled, th e Base G updates include:

Adding Stage II refueling emissions cal culations to the SMOKE processing.

Revised the HDD compliance for all states. (REBUILD EFFECTS = .1)

In addition to the global changes, individual VISTAS states made the following updates:

KY – updated VMT and M6 input values for selected counties.

NC – revised VMT and re gistration distributions.

TN - revised VMT and vehicle registrati on distributions for selected counties.

VA – revised winter RFG calcula tions in Mobile 6 inputs.

WV – revised VMT input data.

AL, FL, and GA did not provide updates for Base G and therefore the Base F inputs were used
for these States.

1.3.1.1 Emissions from on-road mobile sources
The MOBILE6 module of the Sparse Matrix Op erator Kernel Emissions (SMOKE) model was used to develop the on-road mobile source emissions estimates for CO, NO X 

# , NH 3 

# , SO 2 

# , PM, and VOC emissions. The MOBILE6 parameters, vehicl e fleet descriptions, and VMT estimates are combined with gridded, episode-specific temperatur e data to calculate the gridded, temporalized
emission estimates. The MOBILE6 emissions fact ors 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;

#  Facility speeds;

 Locale-specific inspection/maintenance (I/M) control programs, if any;

 Adjustments for running losses;

 Splitting of evaporative and exhaust emi ssions into separate source categories;

 VMT, fleet turnover, and changes in fuel composition and Reid vapor pressure (RVP).

The primary input to MOBILE6 is the MOBILE shell file. The MOBILE shell contains the various options (e.g. type of inspection and maintenance program in effect, type of oxygenated fuel program in effect, alternative vehicle mix pr ofiles, RVP of in-use fuel, operating mode) that
direct the calculation of the MOBILE6 emissions factors. The shells used in these runs were based on VISTAS Base F modeling inputs as noted in the previous section.

For this analysis, the on-road mobile source emissions were produced using selected weeks (seven days) of each month and using these days as representative of the entire month. This selection criterion allows for the representation of day-of-the-week variability in the on-road motor vehicles, and models a representation of the meteorological variab ility in each month. The
modeled weeks were selected from mid-m onth, avoiding inclusion of major holidays.

The parameters for the SMOKE runs are as follows:

# 1.3.2 Development of non-road emission estimates

Emissions from non-road sources were estimated in two steps. First, emissions for non-road
sources that are included in the NONROAD model were deve loped. Second, emissions from
sources not included in the NONR OAD model were estimated. The sections below detail the procedures used for each group of sources.

1.3.2.1 Emissions from NONROAD model sources
An initial 2002 base year emissions inventory for non-road engines and equipment covered by
the EPA NONROAD model was prepared for VISTAS in early 2004. The methods and assumptions used to develop the inventor y are presented in a February 9, 2004 report

“ Development of the VISTAS Draft 2002 Mobi le Source Emission Inventory (February 2004 Version) ” as prepared by E.H. Pechan & Associates, Inc. Except as otherwise stated below, all aspects of the preparation met hodology documented in that repor t continue to apply to the
revised NONROAD mo deling discussed in this section.

Revisions to the initial 2002 NONROAD emissions inventory we re implemented to ensure that
the latest State and local data were considere d, as well as to more accu rately reflect gasoline
sulfur contents for 2002 and correct other State-specific discrepanc ies. Those revisions comprise the Base F VISTAS non-road inventory. This sec tion details the specific revisions made to the NONROAD model input files for the Base F and Base G VISTAS base year inventories, and provides insight into some key differences between the versions of the NONROAD model employed for the Base F and Ba se G inventories and the prev ious version employed for the initial 2002 base year inve ntory prepared by Pechan.

Revisions to the initial 2002 emissions inventory prepared by Pechan were actually implemented in two stages. An initial set of revisions was implemented in the fall of 2004. Those revisions
resulted in the Base F inventor y. These were followed by a second set of revisions in the spring

# of 2006. Those estimates produced the Base G base year inventory. To accurately document the combined effects of both sets of revisions, each set is discussed separately below. Unless otherwise indicated, all revisions implemented in Base F were carried directly into the Base G revision process without change. Thus, the invent ories that resulted from the Base F revisions served as the starting poin t for the Base G revisions.

For Base F, three VISTAS States provided de tailed data revisions for consideration in developing revised model i nputs. These States were:

1. North Carolina
2. Tennessee (including a separate su bmission for Davidson County), and
3. Virginia.
The remaining seven VISTAS States indicated th at the initial 2002 VISTAS input files prepared by Pechan continued to reflect the most re cent data available. These States were:

1. Alabama,
2. Florida,
3. Georgia,
4. Kentucky,
5. Mississippi,
6. South Carolina, and
7. West Virginia.
However, it should be recognized that the NONROAD input files for all ten VISTAS States were updated to reflect gasoline sulfur content revisions for the Base F 2002 base year inventory (as discussed below). The original files prepared by Pechan are available on their FTP site in the /pub/VISTAS/MOB_0104/ directory.

Before presenting the specific implemented revisi ons, it is important to note that the Base F 2002 base year inventory utilized a newer release of the NONROAD model than was used for the initial 2002 base year inventory (prepared by Pechan). The Base F 2002 base year inventory, as developed in spring 2004, was based on the Dr aft NONROAD2004 model, which was released by the EPA in May of 2004. This model is no lo nger available on EPA’s website. The initial 2002 base year inventory (prepared by Pech an) was based on the Draft NONROAD2002a version of the model (which is also no longe r available on EPA’s website). Key differences
between the models are as follows:

 Draft NONROAD2004 included the effects of th e Tier 4 non-road engine and equipment standards (this did not impact the Base F 2002 inventory estimates, but did affect Base F future year forecasts).

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 52 

#  Draft NONROAD2004 included the exhaust emission impacts of the large spark-ignition engine standards; the evaporativ e impacts of these standards are not incorporated (this does not impact 2002 inventory estimates, but does affect future year forecasts).

 Draft NONROAD2004 included revised equipment population estimates.

 The PM 2.5 

# fraction for diesel equipment in Draft NONROAD2004 had been updated from
0.92 to 0.97.

 Draft NONROAD2004 included revisi ons to recreational marine activity, useful life, and
emission rates.

To the extent that these revisions affect 2002 em issions estimates, they will be reflected as
differentials between the initial and Base F 2002 VI STAS base year invent ories. It is perhaps important to identify that, at the time of the Base F inventory revisions; the EPA recognized the
Draft NONROAD2004 model as an appropriate mechanism for SIP development. Although the model was designated as a draft update, it re flected the latest and most accurate NONROAD planning data at that time, as evidenced by th e EPA’s use of that version for the Tier 4 Final Rulemaking.

Prior to the Base G inventory revisions implemented in 2006, th e EPA released another updated version of the NONROAD model, designate d as Final NONROAD2005 (which can be downloaded from: http://www.epa.gov/OMSWWW/nonrdmdl.htm#model). This version ostensibly represents the final version of the model, although certain components of it have been updated since its first release in December 2005. For the Base G inventory developed in the first half of 2006, all updates of the Final NONROAD2005 model through March 2006 are included. Key differences between Final NONROAD 2005 and Draft NONROAD2004 are as follows:

 Final NONROAD2005 reflects the latest basic emission rate and deterioration data.

 Final NONROAD2005 includes emission estimates for a range of evaporative emissions categories not included in Draft NONROAD 2004 (tank and hose permeation, hot soak, and running loss emissions).

 Final NONROAD2005 includes a revise d diurnal emissions algorithm.

 Final NONROAD2005 includes a revised equipment scrappage algorithm.

 Final NONROAD2005 includes revised state and county equipment allocation data.

 Final NONROAD2005 allows separate sulfur content inputs for marine and land-based
diesel fuel.

 Final NONROAD2005 includes revised convers ion factors for hydrocarbon emissions.

#  Final NONROAD2005 includes the evapora tive emission impacts of the large spark-ignition engine standards (this does not impact 2002 inventory estimates, but does affect future year forecasts).

Unfortunately, due to the extensive revisions associated with Final NONROAD2005, input files created for use with Draft NONROAD2004 (e.g., Base F input files) and earlier versions of the model cannot be used directly with Final NONROAD2005 (used for Base G). This created a rather significant impact in that the VI STAS NONROAD modeling process involves the consideration of over 200 unique sets of input data. To avoid crea ting new input files for each of these datasets, a conversion process was undertaken wherein each of the Draft NONROAD2004 (Base F) input data files were converted into the proper format required for proper execution in Final NONROAD2005 (Base G). 1 

# This process consisted of the following steps:

 Revise the Draft NONROAD2004 (Base F) input files to include th e following two line EPA-developed comment at the end of the i nput file header (thi s is a nonsubstantive change implemented solely for consistency wi th input files produced directly using Final NONROAD2005):

# Note that the value 0.2638 (2638 parts per millio n by weight [ppmW]) is applicable only for 2002 modeling and was accordingly revised (as described below) for both the 2009
and 2018 Base G forecast inventories. The 2638 ppmW sulfur value for 2002 marine
diesel fuel was taken from the 48-State (excludes Alaska a nd Hawaii) tabulation presented in the April 27, 2004 EPA document “ Diesel Fuel Sulfur Inputs for the Draft

## The necessary conversions where deve loped by comparing substantively identical input files created using the

graphical user interfaces for both Draft NONROAD2004 and Final NONROAD2005. The di fferences between the input files indicated the specific revisions necessary to convert existing VISTAS input files into Final NONROAD2005 format.

# NONROAD2004 Model used in the 2004 Non-road Diesel Engine Final Rule .” It should
also be noted that this value differs by about 5 percent from the 2500 ppmW value previously used for the initial 2002 VISTAS modeling (performed by Pechan). Prior to Final NONROAD2005 (used for Base G), the NONROAD model allowed only a single diesel fuel sulfur input that was applied to both land-base d and marine equipment. As documented in the February 9, 2004 report “ Development of the VISTAS Draft 2002 Mobile Source Emission Inventory (February 2004 Version) ” as prepared by E.H. Pechan & Associates, Inc., a value of 2500 ppmWsulfur was used for all 2002 VISTAS NONROAD modeling. Given the ability of Final NONROAD2005 to distinguish a separate sulfur content for marine equi pment and the existing EPA guidance document suggesting an appropriate marine sulfur value of 2638 ppmW for 2002, the existing modeling value of 2500 ppmW was modifi ed (for marine equipment only).

The only additional revisions implemented to develop a Final NONRO AD2005-based inventory (Base G) involved elimination of non-default equipment allocation files for North Carolina and West Virginia. Due to concerns about imprope r equipment allocation acr oss counties under the Draft NONROAD2004 model (used for Base F), as well as for earlier versions of the NONROAD model, North Carolina had produced alte rnative allocation data files indicating the number of employees in air tr ansportation by county, the number of wholesale es tablishments by county, and the number of employees in landsca ping services by county. For the same reason, West Virginia had produced alternative equipm ent allocation files indicating the number of employees in air transportation by county, the tonnage of underg round coal production by county, the number of golf courses and count ry clubs by county, the number of wholesale establishments by county, the number of employ ees in logging operations by county, the number of employees in landscaping services by count y, the number of employees in manufacturing operations by county, the number of employees in oil and gas drilling and extraction operations by county, and the number of recreational ve hicle parks and campgrounds by county. These alternative equipment allocation files were us ed for all VISTAS inventory modeling conducted prior to the release of Fi nal NONROAD2005 (i.e., through Base F). However, both North Carolina and West Virginia determined that the de fault allocation file revisions associated with
the release of Final NONROAD2005 we re appropriate to address the concerns that led to the development of the alternative allocation files. As a result, all alternative allocation file
commands were removed from VISTAS N ONROAD2005 (Base G) input files for North Carolina and West Virginia, so that the entire region under the Base G i nventory is now modeled using the default allocation f iles provided with NONROAD2005.

# In addition to the alternativ e equipment allocation files, North Carolina had previously developed an alternative seasonal adjustment file that was used for the Base F inventory in place of the default file provided with Draft NONROAD2004 (and ear lier model versions). The alternative data file implemen ted a single change, namely reclassifying North Carolina as a
southeastern state rather than a mid-Atlantic state (as identified in the default data file). Since Final NONROAD2005 continues to identify North Carolina as a mid-A tlantic state, North Carolina requested that the southeastern re classification be con tinued for all NONROAD2005 modeling (Base G). To ensure that any other revi sions associated with the seasonal adjustment
file released with NONROAD2005 we re not overlooked, the previ ously developed alternative seasonal adjustment file for North Carolina was scrapped and a new altern ative file was created from the default seasonal adjustment file provided with Final NONROAD2005 for Base G inventory development. The alternative file, which was used for all North Carolina modeling,
reclassifies North Carolina from a mid-Atlantic to a southeastern state. This represents the only
non-default data file used for VIST AS NONROAD2005-based (Base G) modeling.

The remainder of this section documents all chan ges to the originally established VISTAS input file values as documented in the February 9, 2004 report “ Development of the VISTAS Draft 2002 Mobile Source Emission Inventory (February 2004 Version) ” as prepared by E.H. Pechan & Associates, Inc. Unless specifically stated belo w, all values from that report continue to be used without change in th e latest VISTAS modeling.

Base F Revisions:
For the initial 2002 base year inventory (devel oped by Pechan), all NONROAD modeling runs for VISTAS were performed utilizing a gasoline sulfur content of 339 ppmW and a diesel sulfur content of 2,500 ppmW. Although th e EPA-recommended non-road dies el fuel sulfur content for 2002 is 2,283 ppmW, the 2,500 ppmW sulfur content us ed for the initial 2002 base year VISTAS inventory was designed to remove the effect of lower non-road diesel fuel sulfur limits applicable only in California. (The EPA recommended inputs can be found in “ Diesel Fuel Sulfur Inputs for the Draft NONROAD2004 Mode l used in the 2004 Non-road Diesel Engine
Final Rule ,” EPA, April 27, 2004.) This correction is a ppropriate and was reta ined for the Base F 2002 inventory. Thus, the Base F inventory continued to assume a diesel fuel sulfur content of 2,500 ppmW across the VISTAS region.

However, 339 ppmW is not the EPA recomme nded 2002 gasoline sulfur content for either eastern conventional gasoline areas or Fede ral Reformulated Gasoline (RFG) areas. The
recommended sulfur content for eastern conv entional gasoline is 279 ppmW year-round, while
the recommended sulfur content for RFG areas is 129 ppmW during the summer season and 279 ppmW during the winter season. (Conventional gasoline and RFG sulfur contents for 2002 can
be found in “ User’s Guide to MOBILE6.1 and MOBILE6.2, Mobile Source Emission Factor

# Model ,” EPA420-R-03-010, U.S. EPA, August 2003 [pages 149-155] (available at link at http://www.epa.gov/otaq/m6.htm ) and in the source code for MOBILE6.2 at Block Data BD05.)
Given the differences in the EPA-recommended valu es and the value used to generate the initial 2002 base year inventory, the input files for Base F for all VISTAS areas were updated to reflect revised gasoline sulfur content assumptions.

Since the VISTAS NONROAD modeling is perfor med on a seasonal basis, and since gasoline
sulfur content in RFG areas varies with th e RFG season, seasonally-spe cific gasoline sulfur
content values were estimated for use in RFG area modeling. In addition, 25 counties in Georgia are subject to a summertime gasoline sulfur lim it of 150 ppmW, so that seasonal sulfur content
estimates were also estimated for these counties. The initial 2002 base year NONROAD inventory (prepared by Pechan) for these Georgia counties was based on a year-round 339 ppmW gasoline sulfur content, but that oversight was corrected in the Base F 2002 base year inventory. Based on the seasonal definitions empl oyed in the NONROAD m odel, monthly sulfur contents were averaged to estimate seasonal gasoline sulfur contents as follows:

# Note that the seasonal data are based on simple arithmetic averages and do not consider any monthly variation in activity (and fuel sales), a nd that the transition betw een summer and winter seasons is also not considered. Additionally, th e summer fuel control s eason is treated as though it applies from May through September, while the summer RFG season actually ends on September 15 and the Georgia fuel control season does not officially begin until June 1. This
treatment is consistent with the treatment of both fuel control programs in the VISTAS on-road vehicle modeling. Each of these influences will result in some error in the estimated sulfur content estimates, but it is expect ed that this error is small rela tive to the overall correction from a year-round sulfur content estimate of 339 ppmW.

All NONROAD modeling revisions made as part of the Base F inve ntory preparation process are presented in Table 1.3-2. Due to more involve d updates in several areas, the number of NONROAD input files as well as sequence numbers used to represent these files was also updated in a few instances (as compared to the files used to create the initial 2002 VISTAS nonroad inventory, as documented in the February 9, 2004 report “ Development of the VISTAS Draft 2002 Mobile Source Emission Inventory (February 2004 Version) ” as prepared by E.H.

# Base G Revisions:
As described above, the primary modeling revi sion implemented for the Base G 2002 inventory
was the use of the Final NONROAD2005 model (in place of the Base F use of Draft NONROAD2004). However, there we re other minor revisions implemented for 13 Georgia counties and somewhat more significant revisions implemented for Tennessee. In Georgia, Stage II refueling control was assume d for 13 counties that previous ly were modeled as having no refueling control under Base F. In addition, to accommodate th is Stage II change as well as forecast year changes in gasoline vapor pressu re, corresponding changes in the structure and sequence of Georgia NONROAD input files were made. With the exceptio n of the minor Stage II impacts, these structural and sequence cha nges have no impact on 2002 emission estimates, but allow for consistency between 2002 and forecas t year input file structure and sequence. In Tennessee, more significant changes were implem ented to gasoline vapor pressure assumptions, as well as similar minor changes in St age II refueling control assumptions.

In accordance with instructions from Georgia regulators, Stage II refueling control was assumed in the following 13 Georgia counties at a cont rol efficiency value of 81 percent for the Base G inventory:

Cherokee, Clayton, Cobb, Coweta, DeKa lb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale.

No Stage II control was assumed in th ese counties in pr ior inventories.

Tennessee regulators provided revi sed monthly values for gasoline vapor pressure. Based on the seasonal definitions employed in the NONROAD model, monthly va por pressures were averaged to estimate seasonal vapor pressures as follows:

# As with the Base F revisions, the seasonal data are based on simple arithmetic averages and do not consider any monthly varia tion in activity (and fuel sales) , nor is the transition between
summer and winter seasons considered. Additiona lly, a monthly average of the September 1-15 and September 16-30 data is cal culated prior to averaging th e September-November data to estimate a fall average vapor pressure, so that the month of September is we ighted identically to
the months of October and November.

Tennessee regulators also indicate d that Stage II vapor recovery was not in effect in Shelby County, so the Base F NONROAD input files for th e county (which assu med Stage II was in place) were revised accordingly.

All Base G NONROAD modeling re visions are presented in Tabl e 1.3-4. As indicated above, the differentiation of inputs across previously grouped counties also required revision to the overall number and sequence of VISTAS N ONROAD input files (as compared to the files used to create both the initial VISTAS non-road inventory, as documented in the February 9, 2004 report

# 1.3.2.2 Emissions from Commercial Marine Ve ssels, Locomotives, and Airplanes
An initial 2002 base year emissions inventory for aircraft, locomotives, and commercial marine vessels (CMV) was prepared for VISTAS in ear ly 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) ” as prepared by E.H. Pechan & Associates, Inc. A summary of the initial 2002 ba se year emissions inventory is presented in Table 1.3-6. Except as otherwise stated below, all aspects of the preparation methodology continue to apply to the Base F and Base G emission inventories.

Revisions to the initial 2002 emissions inventory (prepared by Pechan) were implemented to
ensure that the latest State and local data were incorporated as well as to correct an
overestimation of PM emissions from aircraft . Revisions were actually implemented in two stages. An initial set of revisions was implemente d in the fall of 2004. Those revisions constitute the Base F inventory. These were followed by a s econd set of revisions in 2006, which constitute the Base G inventory. To accurately document the combined effects of both sets of revisions, each set is discussed separately below. Unless ot herwise indicated, all re visions implemented for Base F were carried directly into the Base G revision pro cess without change. Thus, the
inventories that resulted from the Base F revisions served as the starting point for the Base G
revisions.

Base F Revisions:

Revisions to the initial 2002 base year emissions inventory we re implemented to ensure that the latest State and local data were incorporated as well as to correct an overestimation of PM
emissions from aircraft. Seven of the ten VISTAS States provided revised inventory data in the form of emissions reported to the EPA under the CERR. States provi ding CERR data were Alabama, Georgia, Mississippi, North Ca rolina, Tennessee (excluding Davidson, Hamilton, Knox, and Shelby Counties), Virginia, and West Virginia.

In many cases, the CERR data were only margina lly different than the initial 2002 base year inventory data, but there were several instances where signific ant updates were evident. The remaining three VISTAS States (Florida, Ke ntucky, and South Carolina), plus Davidson, Hamilton, Knox, and Shelby counties in Tennessee, indicated that the initial 2002 VISTAS inventory continued to reflect the most recent data available. Flor ida did provide updated aircraft emissions data for one county (Miami-Dade) and th ese data were incorpor ated into the Base F 2002 inventory as described below.

Since several States recommended re taining the initial 2002 base year inventory data for Base F, the initial step toward revising the 2002 inventory cons isted of modifying the estimated aircraft
PM emissions of the initial inve ntory. The overestimation of aircraft PM became evident shortly

# after the release of th e initial 2002 base year inventory, wh en it was determined that VISTAS region airports would constitute the top seven, and 11 of the top 15, PM sources in the nation. Moreover, PM emissions for one airport (Miami International) were a full order of magnitude larger than all other modeled elemental carbon PM em ission sources. In addition, unexpected relationships across airports we re also observed, with emissi ons for Atlanta’s Hartsfield International being substantially less than thos e of Miami International, even though Atlanta handles over twice as many aircraft operations annually. Given the pervasiveness of this problem, and since the CERR data submitted by St ates was based on the initial 2002 VISTAS inventory data, aircraft PM emissions for th e entire VISTAS regi on were recalculated.

# Aircraft do emit PM while operating. However, offi cial EPA inventory procedures for aircraft generally do not include PM emi ssion factors and, therefore, aircra ft PM is generally erroneously reported as zero. In an effort to overcome this deficiency, the developers of the initial VISTAS 2002 base year aircraft inventory (Pechan) estim ated PM emission rates for aircraft using
estimated NO x 

# emissions and an unreported PM-to-NO x 

# ratio (i.e., PM = NO x 

# times a
PM-to-NO x 

# ratio). According to the initial 2002 ba se year inventory documentation, this approach was applied only to commercial aircraft NO x 

# , but a review of that inventory indicates that the technique was also applied to military, ge neral aviation, and air taxi aircraft in many, but not all, instances. Although there is nothing inhere ntly incorrect with this approach, the accuracy and inconsistent applicati on of the assumed PM-to-NO x 

# ratio results in grossly overestimated
aircraft PM.

Through examination of the initial 2002 base year aircraft inve ntory (prepared by E.H. Pechan and Associates, Inc.), it is apparent that the commercial aircraft PM-to-NO x 

# ratio used to generate PM emission estimates was appr oximately equal to 3.95 (i.e., PM = NO x 

# times 3.95). While the majority of observed commercial aircraft PM-to-NO x 

# ratios in that inventory are equal to 3.95, a few range as low as 3.00. If all aircraft estimates are included (i.e., commercial plus military, general aviation, and air taxi), observed PM-to-NO x 

# ratios range from 0 to 123.0, and average 3.43 as illust rated in Table 1.3-7

# in the initial 2002 base year inve ntory dataset). Regardless, based on previous statistical analyses performed in support of aircraft emissions inve ntory development outside the VISTAS region, a
PM-to-NO x

In analyses performed for the Tucs on, Arizona planning area, PM-to-NO x 

# ratios for aircraft over a standard aircraft landing and takeoff (LTO) cycl e are shown in Table 1.3-8. Data for this table
is taken from “Emissions Inventories for th e Tucson Air Planning Ar ea, Volume I., Study Description and Results,” prepared for the Pi ma Association of Governments, Tucson, AZ, November 2001. Pages 4-40 through 4-42 of that report, which document the statistical derivation of these ratios, are include d in this report as Appendix E.

Note:
The PM and NO x emission estimates presented in the Tucson study are for lo cal aircraft operating mode ti mes. For this work, emission estimates for Tucson were recalculated for a standard LTO cycle, so that the ratios presented are applicable to the standard LT O cycle and not a Tucson-specific cycle. Thus, the ratios presented herein vary somewhat from thos e associated with the emission estimates presented in the Tucson study report.

# Aircraft PM-to-NO x 

# ratios vary with operating mode, so that aircraft at airports with mode times that differ from the standard cycle will exhibit varying ratios. However, conducting an airport-sp ecific analysis for all airports in the VISTAS region was beyond the scope of this work. While local PM-to-NO x 

# ratios could vary somewhat from the indicated standard cycle ratios, any error due to this variation will be significantly less than the order of magnitude error associat ed with the 3.95 commercial aircra ft ratio used for the initial 2002 base year inventory.

It should be recognized that wh ile the Tucson area is far removed from the VISTAS region, the data analyzed to generate the PM-to-NO x

# ratios in the Base F inventory, all aircraft PM records were
removed from the initial 2002 base year inventory (prepared by Pe chan). This includes records for which local planners may have estimated PM emissions. This approach was taken for two reasons. First, there is no way to distinguish which records may have been generated by local planners. Second, the data available to local planne rs may be no better than that used to generate the presented PM-to-NO x 

# ratio data, so the consistent app lication of these data to the entire VISTAS region was determined to be the most appropriate approach to generating consistent inventories throughout the region. In undertaking this removal, it became apparent that there was
an imbalance in the aircraft NO x 

# and PM records in the initial 2002 base year inventory. Whereas there were 1,531 NO x 

# records in the NIF emission data sets for this source category, there were only 1,212 PM records. The imbalance was distri buted between three States, South Carolina, Tennessee, and Virginia as follows:

no air taxi PM emissions without other combusti on-related emissions. Thus, the removal of the

PM 10 

# and PM 2.5 

# records for Hamilton County permanently reduced the overall size of the 2002 initial base year inventory database used as a starting point for Base F by two records.

## 72 

# Of the 320 unmatched NO x 

# records, 269 were records for whic h the reported emission rate was zero. Therefore, even though associated PM reco rds were missing, the overall inventory was not affected. However, the 51 missing records for which NO x 

# emissions were non-zero, did impact PM estimates for the overall inventory.

Replacement PM 10 

# records were calculated for all aircraft NO x 

# records using the PM-to-NO x 

# ratios presented above. Aircraft type-specific ratios were utilized in all cases, except for two counties where aircraft emissions were reported under the generic aircraft SCC 2275000000. For these counties (Palm Beach County, Florida a nd Davidson County, Tenne ssee), the commercial
aircraft PM-to-NO x 

# ratio was applied since both contain commercial airports (Palm Beach
International and Nashvi lle International).

Replacement aircraft PM 2.5 

# records were also developed. Th e initial 2002 base year inventory
assumed that aircraft PM 2.5 

# was 69 percent of aircraft PM 10 

# . The origin of this fraction is not clear, but it is very low for combustion related PM. The majority of internal combustion engine related PM is typically 1 micron or smaller (PM 1.0 

# ), so that typical inte rnal combustion engine

PM 2.5 

# fractions approach 100 percent. For ex ample, the EPA NONROAD model assumes 92 percent for gasoline engine pa rticulate and 97 percen t for diesel engine particulate. Based on recent correspondence from the EPA, it appears th at the agency is preparing to recommend a
PM 2.5 

# fraction of 98 percent for aircraft. (Augus t 12, 2004 e-mail correspondence from U.S. EPA to Gregory Stella of Alpine Geophys ics.) This is substant ially more consistent with expectations
based on emissions test data for other internal combustion engine sources and was used as the
basis for the recalculated aircraft PM 2.5 

# emission estimates in the Base F inventory.

Although a substantial portion of the initial 2002 base year inventory was ultimately replaced with data prepared by State and local planners under CERR requirements in developing the Base F inventory, it was necessary to first revise the initial 2002 base year aircraft inventory as
described so that records extr acted from the inventory for area s not supplying CERR data for the Base F update would be accurate. Therefore, in no case is the aggregated St ate data reported for the Base F inventory identical to that of the in itial 2002 base year inventory. Even areas relying on the initial 2002 base year inventory will reflect updates in Base F due to changes in emissions
of PM 10 

# and PM 2.5 

# from aircraft.

Table 1.3-10 presents the updated initial 2002 base year inventory estimates. These estimates do not reflect any changes related to modifications made to incorporate the CERR data, but instead indicate the impacts associated solely with the recalculation of aircraft PM emissions alone to apply the more appropriate PM to NO x 

# ratios. Table 1.3-11 presents a summary of the net impacts of these changes, where an over 90 percen t reduction in aircraft PM is observed for all VISTAS areas except South Carolina and Virginia. The reasons for the lesser changes in these
two States is that the overall aircraft NO x 

# inventories for both include a large share of military

# aircraft NO x 

# to which no (or very low) particulate estimates were assigned in the initial 2002 base year inventory. Since these operations are assigned non-zero PM emissions under the revised approach, the increase in military airc raft PM offsets a portion of the reduction in commercial aircraft PM. In Virgin ia, zero (or near zero) PM milita ry operations were responsible for about 35 percent of total aircraft NO x 

# , while the corresponding frac tion in South Carolina was almost 70 percent. As indicated, aggregate aircraft, locomotive, and commercial marine vessel PM is 70-75 percent lower in th e updated 2002 base year inventory.

# As indicated above, for the Base F 2002 base year inventory, data for al l or portions of seven VISTAS States were replaced with corresponding data from recent (as of the fall of 2004) CERR submissions for 2002. Before replacing these data, however, an analysis of the CERR data was performed to ensure consistency with VISTAS inventory methods. It should perhaps also be noted that three of the CERR datasets provi ded for the Base F 2002 base year inventory (specifically those for Tennessee, Virginia, a nd West Virginia) included both annual and daily emissions data. Only the annual data were used. Daily values were removed.

# Several important observations resu lted from this analysis. First, it was clear that all of the CERR data continued to rely on the inaccurate ai rcraft PM estimation approach employed for the initial 2002 base year inventory. Therefore, an id entical aircraft PM replacement procedure as described above for updating the initial 2002 ba se year inventory was undertaken for CERR supplied data. As a result, the CERR data for all VISTAS States has been modified for inclusion in the Base F 2002 VISTAS base year inve ntory due to PM replacement procedures.

As was the case with the initial VISTAS 2002 ba se year inventory, ther e were a substantial
number of aircraft NO x 

# records without corresponding PM records, so that the number of
recalculated PM records added to the CERR dataset is greater than the number of PM records removed. The aggregated CERR inventory data, reflecting data for all or parts of seven States, consisted of 13,656 records, of which 1,211 were aircraft NO x 

# records. However, the number of corresponding aircraft PM records was 662 (662 PM 10 

# records and 662 PM 2.5 

# records). This
imbalance was distributed as follows:

Table 1.3-12 CERR Aircraft NO x 

# Records with No Corresponding PM Record.

Aircraft Type Georgia Tennessee Virginia Total
Military Aircraft 136 136

Commercial Aircraft 4 136 140

General Aviation Aircraft 1 136 137

Air Taxi Aircraft 136 136
Aggregate 1 4 544 549



# From this tabulation, it is clear th at virtually the entire imbalance is associated with the Virginia CERR submission, with minor imbalances in Georgia and Tennessee. Of the 549 unmatched
NO x 

# records, 461 were records for which the repo rted emission rate was zero. Therefore, even though the associated PM records were missi ng, the overall inventory was not affected. However, the 88 missing records for which NO x 

# emissions were non-zero do impact PM emission estimates for the overall inventory.

Replacement aircraft PM records (both PM 10 

# and PM 2.5 

# ) were generated for the CERR dataset using procedures identical to those descri bed above for the upda ted initial 2002 base year inventory.

Further analysis revealed that the CERR da ta for Virginia incl uded only VOC, CO, and NO x 

# emissions for all aircraft, locomotives, a nd non-recreational marine vessels. Since SO 2 

# , PM 10 

# , and PM 2.5 

# records are included in the 2002 VISTAS inventory, an estimation method was developed for these emission species and appl ied to the Virginia CERR data. For PM, the

# developed methodology was only employed for locomo tive and marine vessel data since aircraft PM was estimated using the PM-to-NO x 

# ratio methodology described above.

Consideration was given to si mply adding the Virginia SO 2 

# and non-aircraft PM records from the initial 2002 VISTAS inventory datase t, but it is very unlikely that either the source distribution
or associated emission rates are identical across the CERR and initial VISTAS inventories. This was confirmed through a comparative analysis of dataset CO records. Therefore, an estimation methodology was developed using Virginia source-specific SO 2 

# /CO, PM 10 

# /CO, and PM 2.5 

# /PM 10 

# ratios from the initial 2002 base year VISTAS inventory. The calculated ra tios were then applied to the source-specific CERR CO emission estima tes to derive associated source-specific SO 2 

# , PM 10 

# , and PM 2.5 

# emissions for the Base F inventory.

Initially, the development of the emissions ratio s from the initial 2002 base year inventory was performed at the State (i.e., Vi rginia), county, and SCC level of detail. However, it readily
became clear that there were s ubstantial inconsistencies in ra tios for identical SCCs across counties. For example, in one county, the SO 2 

# /CO ratio might be 0.2, while in the next county it
would be 2.0. Since the sources in question are virtually identical (e.g., diesel locomotives) and since the fueling infrastructure for these large non-road equipmen t sources is regional as opposed to local in nature, such variations in emission rates are not realistic. Therefore, a more aggregated approach was employed in which SCC-specific emi ssion ratios were developed for the State as a whole. Through this approach county-to-county vari ation in emission ratios is eliminated, but the underlying variation in CO emissi ons does continue to influence the resulting aggregate emission estimates. The applied emission ratios are as follows:

# It is important to recognize that the inconsistenc y of emissions ratios ac ross Virginia counties for sources of virtually identical design, which utilize a regiona l rather than local fueling infrastructure, has potential im plications for other VISTAS States. There is no immediately
obvious reason to believe that such inconsis tencies would be isolated to Virginia.

One final revision to the CERR dataset was undertaken as part of the Base F effort, and that was the removal of two records for unpaved airs trip particulate (SCC 2275085000) in Alabama. Otherwise identical records for these emissions were reported both in terms of filterable and primary particulate. The filterable particulate records were removed as all other particulate
emissions in the VISTAS inventorie s are in terms of prim ary particulate. It is also perhaps worth noting that a series of aircraft refueling r ecords (SCC 2275900000) for Virginia were left in place, even through typically such emissions would be reported under SCC 2501080XXX in the area source inventory. If additiona l VISTAS aircraft refueling emissions are reported under SCC 2501080XXX, then it may be desirabl e to recode these records.

Finally, data for areas of the VISTAS region not represented in the CERR dataset were added to the CERR data by extracting the a ppropriate records from the initial 2002 base year inventory (with revisions for aircraft PM to NO x 

# ratios). Specifically, records applicable to the States of Florida, Kentucky, South Carolina, and the Te nnessee counties of Davidson, Hamilton, Knox, and Shelby were extracted from the revised initial 2002 inventory and added to the CERR dataset to establish the 2002 Base F inventory.

Following this aggregation, one last dataset revision was implemented to complete the development of the 2002 Base F inventory. As indicated in the introduction of this section, the initial 2002 base year emission estimates for Miami International Airport were determined to be excessive. Although the reason for this inaccuracy was not apparent, revised estimates for
aircraft emissions in Miami-Da de County were obtained from Florida planners and used to overwrite the erroneous estimates. (Aircraft emi ssion estimates were provided in an August 10,
2004 e-mail transmittal from Bruce Coward of Miam i-Dade County to Martin Costello of the Florida Department of Environmental Protection.)

Table 1.3-14 presents a summary of the resul ting Base F VISTAS 2002 base year inventory estimates for aircraft, locomotives, and non-recr eational marine vessels. Table 1.3-15 provides a comparison of the Base F 2002 base year inventor y estimates to those of the initial 2002 base year inventory. As indicated, total emissions for VOC, CO, NO x 

# , and SO 2 

# are generally within 10 percent, but final PM emissions are reduced by 70-80 percent due to the approximate 90 percent reductions in aircraft PM estimates. In addition, the significant changes in Georgia
aircraft emissions are due to the CERR correcti on of Atlanta Hartsfield International Airport emissions, which were significantly underestimated in the initial 2002 base year inventory. The

## 78 

# reduction in Florida aircraft emi ssions due to the correction of Miami International estimates is also apparent.

Lastly, Table 1.3-16 provides a direct comparison of emission estimates from the initial and Base F 2002 base year inventories for all 16 VISTAS region airports with es timated annual aircraft
NO x 

# emissions of 200 tons or greater (as identifie d at the conclusion of the Base F revisions). 3



# The table entries are sorted in order of decreasing NO x 

# and once again, the dramatic reduction in PM emissions is evident. However, in additi on, the appropriate reversal of the relationship
between Atlanta’s Hartsfield and Miami Intern ational Airport is also depicted. As a rough method of quality assurance, Table 1.3-15 also includes a gross estimate of expected airport NO x 

# emissions using detailed NO x 

# estimates developed for Tucson International Airport in conjunction with the ratio of local to Tucson LTOs. (The Tucson NO x 

# estimates are revised to reflect a standard LTO cycle rather than the Tu cson-specific LTO cycle. This should provide for a more realistic comparison to VISTAS estimates.) This is not meant to serve as anything other than a crude indicator of the propriety of the deve loped VISTAS estimates, and it is clear that the range of estimated-to-expected NO x 

# emissions has been substantia lly narrowed in the Base F 2002 base year inventory. Whereas estimated-to- expected ratios varied from about 0.2 to over 3.5 in the initial 2002 base year i nventory, the range of variation is tightened on both ends, from about 0.5 to 1.75 for the Base F 2002 base year inve ntory. In effect, all es timates are now within a factor of two of the expected estimates, which is quite reasonable given likely variation in local and standard LTO cycles a nd variations in aircraft fleet mix across airports.

It is perhaps important to note that some shifting in county emissions assignments is evident between the initial and Base F 2002 base year airc raft inventories. For example, for the initial 2002 base year inventory, Atlanta Hartsfield es timates were assigned to Fulton County (FIP 13121), while they are assigned to Clayton Count y (FIP 13063) for the Base F 2002 base year inventory. Similarly, Dulles Intern ational Airport emissions were assigned solely to Fairfax County, Virginia (FIP 51059) in the initial 2002 base year inve ntory, but are split between Fairfax and Loudoun County (FIP 51107) for Base F. Such shifts reflect local planner decision-making and are not an artifac t of the revisions described above.

## Subsequent revisions performed for Base G result in the addition of the Cincinnati/Northern Kentucky

International Airport to the group of airports with ai rcraft operations generating at least 200 tons of NO x 

## . These revisions are discussed below, including the addition of an appropriately modified version of the aircraft emissions table.

Note: For the Base F inventory, Dulles International Ai rport emissions are split betw een two Virginia counties. Predicted NO x is based on the ratio of airport LTOs to test airport (Tucson International Airport) LTOs and NO x . This is not a rigorous comparison, but rather an approximate indicator of expected magnitude.

# Base G Revisions:
Further revisions to the 2002 base year emission s inventory were implemented in response to additional state data submittals in the spring of 2006. The inventories developed through the Base F revision process (as described above) serv ed as the starting point for the 2006 revisions. Thus, unless otherwise indicated below, all documen ted Base F revisions con tinue to apply to the Base G-revised 2002 base year inventory.

As part of the Base G review and update pro cess, Virginia regulators provided 443 updated
emission records for aircraft. These records re flected revisions to ai rcraft VOC, CO, and NO x 

# , and in a few cases SO 2 

# , emissions records that were al ready in the Base F VISTAS 2002 inventory (as opposed to the addition of previ ously unreported data). The specific revisions
broke down as follows:

Commercial Aircraft 12 12 12 17 53

General Aviation Aircraft 65 66 66 0 197

Air Taxi Aircraft 56 56 53 0 165
Aggregate 142 143 140 18 443



# Emissions values for each of the 443 record s in the Base F 2002 VISTAS inventory were updated for Base G to reflect the revised data. However, as described above for the Base F revisions, all aircraft SO 2 

# , PM 10 

# , and PM 2.5 

# emissions in Virginia are estimated on the basis of CO (in the case of SO 2 

# ) and NO x 

# emissions (in the cases of PM 10 

# and PM 2.5 

# ). Therefore, since Virginia regulators did not provide updated SO 2 

# emissions for all updated CO emissions records, or updated PM 10 

# or PM 2.5 

# emissions for all updated NO x 

# emissions records, it was necessary to
re-estimate aircraft SO 2 

# , PM 10 

# , and PM 2.5 

# emissions in all cases where updated CO or NO x 

# emissions were provided for Base G (and explicit SO 2 

# and/or PM 10 

# and PM 2.5 

# emissions were not).

The procedure used to estimate the SO 2 

# , PM 10 

# , and PM 2.5 

# emissions revisions was identical to that described above for the Base F inventory revisions, except that revised SO 2 

# -to-CO emissions
ratios were calculated for commercial airc raft, where 12 pairs of revised CO and SO 2 

# emissions estimates were available. Although a single pair of revised CO and SO 2 

# emissions records was available for military aircraft, this was deemed an insufficient sample with which to replace the military aircraft SO 2 

# -to-CO emissions ratios previously calc ulated in Base F. However, it is worth noting that the SO 2 

# -to-CO emissions ratio for the revised military aircraft emissions pair

# was within 16 percent of the previously calculated ratio, so any error associ ated with retention of
the Base F ratio will be minor. Table 1.3-18 presents the emissions ratios.

# -to-PM 10 

# emissions ratios to the 140 revised aircraft PM 10 

# records resulted in an additional 140 aircraft PM 2.5 

# emission records updates for Virginia. Thus, in total, 853 (443+130+140+140) Virginia aircraft emissions records were updated for Base G.

Also as part of the Base G review and update process, Alabama regulators provided 178 updated PM emission records for aircraft (89 records for PM 10 

# and 89 records for PM 2.5 

# ), 42 additional emissions records for locomotives (14 records for VOC, 14 records for CO, and 14 records for
NO x 

# ), and 179 additional emission records for airc raft (30 records for VOC, 30 records for CO,
30 records for NO x 

# , 29 records for SO 2 

# , 30 records for PM 10 

# , and 30 records for PM 2.5 

# ). After review, it was determined that the 178 update d PM emission records for aircraft actually reflected the original (overestimated) aircraft PM data that was repla ced universally throughout the VISTAS region for Base F. Implementing thes e latest revisions would, in effect, “undo” the Base F aircraft PM revisions. Following discussions with Alabama regulators, it was determined
that the 178 aircraft PM records would not be updated for the Base G revisions.

The 42 additional emissions records for locomotiv es were determined to correspond exactly to existing SO 2 

# , PM 10 

# , and PM 2.5 

# emissions records already in the Base F VISTAS 2002 inventory. It is not clear why these existing records contained no corresponding data for VOC, CO, and
NO x 

# , but those data are now reflected through the additional 42 records that have now been added to the Base G 2002 VISTAS inventory for Alabama.

After examining the 179 additional aircraft em issions records in c onjunction with Alabama regulators, it was determined that 17 of the records (commercial aircraft records in Dale,

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 84 

# Limestone, and Talladega counties) were erroneous and should be excluded from the update. The remaining 162 records reflected additional general av iation, air taxi, and military aircraft activity in 20 counties and were specifically comp rised of 27 records each for VOC, CO, NO x 

# , SO 2 

# , PM 10 

# , and PM 2.5 

# . There were no further i ssues with the VOC, CO, NO x 

# , and SO 2 

# records and
these were added to the Base G 2002 VISTAS inventory without change. It was, however, apparent that the PM 10 

# and PM 2.5 

# records reflected an overestimation of aircraft PM similar to that which was previously corrected throughout the VISTAS region for Base F (as documented above). To overcome this overestimation, the additional aircraft PM 10 

# and PM 2.5 

# records provided by Alabama regulators were replaced with revised emission estimates developed on the
basis of the PM 10 

# -to-NO x 

# and PM 2.5 

# -to-PM 10 

# ratios documented under the Base F revisions above. So although 27 aircraft PM 10 

# records and 27 aircraft PM 2.5 

# records were added to the 2002 Alabama inventory, they reflected different em issions values than those provided directly by Alabama regulators.

In total, 204 additional emissions records (42 for locomotives and 162 for aircraft) were added to the Base G 2002 Alabama inventory.

Finally, as part of the Base G review and update process, Kentucky regulators provided 12 updated aircraft emission records for Boone Co unty, to correct previously underestimated
aircraft emissions associated with the Cincinna ti/Northern Kentucky Inte rnational Airport. VOC, CO, and NO x 

# emissions data were provided for military, commercial, general aviation, and air taxi aircraft. No associated updates for SO 2 

# , PM 10 

# , or PM 2.5 

# emissions were provided. Corresponding PM 10 

# emission estimates were developed by applying the PM 10 

# -to-NO x 

# ratios presented in Table 1.3-17 above to the updated NO x 

# emission estimates. PM 2.5 

# emission estimates were developed by applying the PM 2.5 

# -to-PM 10 

# ratios from that same table to the
estimated PM 10 

# emissions. SO 2 

# emission estimates were developed by applying the SO 2 

# -to-PM 10 

# ratios developed from the older data (i.e., the da ta being replaced) for Boone County aircraft to the updated PM 10 

# emissions. Thus, a total of 24 invent ory records for Kentucky were updated (VOC, CO, NO x 

# , SO 2 

# , PM 10 

# , and PM 2.5 

# for four aircraft types).

Upon implementation of the universe of updates, 877 existing emission records were revised (853 in Virginia and 24 in Kentucky) and 204 add itional emission records (all in Alabama) were added to the 2002 VISTAS inventory. The total nu mber of aircraft, locomotive, and commercial marine inventory records thus changed from 22,838 records in Base F to 23,042 records in
Base G.

Table 1.3-19 presents a summary of the resul ting Base G VISTAS 2002 base year inventory estimates for aircraft, locomotives, and non-recr eational marine vessels. Table 1.3-20 provides a comparison of the Base G 2002 base year inventor y estimates to those of the Base F 2002 base

# year inventory. As indicated, total emissions for VOC, CO, NO x 

# , and SO 2 

# are generally within about 5 percent, with changes restricted to the states of Alabama, Kentucky, and Virginia.

Lastly, Table 1.3-21 provides an updated comparis on of emission estimates from the Base F and Base G 2002 base year inventories for all 17 VI STAS region airports with estimated annual
aircraft NO x 

# emissions of 200 tons or greater. As comp ared to Table 1.3-16, the table reflects the Base G addition of the Cincinnati/Northern Kentucky International Airport. Aircraft emission estimates for the other 16 airports ar e unchanged from their Base F values.

Note: For the revised inventory, Dulles International Air port emissions are split between two Virginia counties. Predicted NO x is based on the ratio of airport LTOs to test airport (Tucson International Airport) LTOs and NO x . This is not a rigorous comparison, but rather an approximate indicator of expected magnitude.

## 1.3.2.3 Emissions from NONROAD Model Sources in Illinois, Indiana, and Ohio
As part of the Base G update process, VISTAS requested that emissions estimates for 2002 be produced for the states of Illinois, Indiana, and Ohio. These estimates were to be produced at the same spatial (i.e., county level by SCC) a nd temporal resolution as estimates for the VISTAS region.

The requested estimates were produced by extracti ng a complete set of c ounty-level input data applicable to each of the three states from th e latest version of th e EPA’s NMIM (National Mobile Inventory Model) model. This included appropriate consideration of all non-default NMIM input files generated by the Midwest Regional Planni ng Organization (MRPO), as described below. These input data were then asse mbled into appropriate i nput files for the Final
NONROAD2005 model and emission estimates we re produced using the same procedure employed for the VISTAS region as part of the Base G updates.

A complete set of monthly input data was deve loped for each county in Illinois, Indiana, and Ohio by extracting data from the following NM IM database files (using the NMIM MySQL query browser):

county, countrynrfile, countyyear, countyyearmonth, countyyearmonthhour, gasoline, diesel, and natural gas

The database files:

countrynrfile, countyyear, countyyearmonth, and gasoline

were non-default database files provided to VI STAS by the MRPO, and are intended to reflect the latest planning data bei ng used by MRPO modelers.

From these files, monthly data for gasoline va por pressure, gasoline oxygen content, gasoline sulfur content, diesel sulfur content for la nd-based equipment, diesel sulfur content for marine-based equipment, natural gas sulfur cont ent, minimum daily temperature, maximum daily temperature, and average daily temperature were developed. In addition, th e altitude and Stage II refueling control status of each county, as well as the identity of the associated equipment population, activity, growth, alloca tion, and seasonal distribution f iles, was determined. These
data were then assembled into Final NONRO AD2005 input files on a seasonal basis, with monthly data being arithmetically averaged to produce seasonal equivalents as follows:

Winter = Average of December, January, and February Spring = Average of March, April, and May Summer = Average of June, July, and August, Fall = Average of September, October, and November

## Unlike the VISTAS Base G approach, this appr oach results in the use of the following
non-default data files during the Final NONROAD 2005 modeling process:

Table 1.3-22 Non-Default Files Used for MRPO Modeling

Specific Fuel Consumption MRPO-specific file provided by MRPO modelers (arbitrarily named “mrpoBSFC.emf” for this work)

One compromise was made relative to the level of resolution that is available through the basic approach described above, that being the treatme nt of ambient temperature data. Because NMIM offers a unique temperature profile for ev ery U.S. county -- developed by aggregating temperature data from included and surrounding weat her stations on the basis of their distances from the county population centroid -- it is not possible to explicitly group counties with
otherwise identical i nput streams. Ungrouped however, th ere would be 1,128 distinct input streams to be processed (102 Illinois counties pl us 92 Indiana counties plus 88 Ohio counties at four seasons each), or over five times th e number of files processed for the entire VISTAS region.

To surmount this problem and allow counties with similar temperature profiles to be grouped an approach was employed wherein counties were considered groupable if all temperature inputs 4



## are within ± 2 oF of the corres ponding group average. This criteri on is quite stringent in that it results in less tolerant grouping than that employed for VISTAS modeling, which uses temperature data from the nearest meteorologica l station as opposed to "unique" meteorological

4 

### Non-road temperature inputs used for county grouping are: winter minimum, spring minimum, summer minimum,

fall minimum, winter maximum, spring maximum, summer maximum, fall maximum, winter average, spring average, summer average, and fall average.

## data for each county. Under this approach, th e actual deviation for grouped counties is much less that ± 2o F for the overwhelming major ity of the 12 grouped temperature inputs.

In addition to the required temperature consis tency, all other input data for counties to be grouped had to be identical for all four seasons . Using this criterion, Illinois emissions were modeled using 12 county groups, Indiana emissions were modeled using 9 county groups, and Ohio emissions were modeled using 10 count y groups. Thus, 31 iterations of NONROAD2002 were required per season, as compared to the 53 iterations per s eason required for the VISTAS region.

It should be noted that a pot ential quality assurance issue was noted in assembling the NONROAD2005 input data for a numb er of Indiana counties. Specifically, the gasoline vapor pressure for most Indiana counties reflects a value of 9.0 psi in all spring, summer, fall, and winter months. This is likely to indicate a problem with the accu racy of the NMIM databases for these counties, but these data were used as defined for this work.

1.3.3 Quality Assurance steps
Throughout the inventory developm ent process, quality assuran ce steps were performed to ensure that no double counting of emissions occurred, and to ensu re that a full and complete inventory was developed for VISTAS. Quality assurance was an important component to the inventory development process and MACTEC performed the following QA steps on the area source component of the 2002 base year revised:

1. All CERR and NIF format State supplied data submittals were run through EPA’s Format and Content checking software.

2. SCC level emission summaries were prepared and evaluated to ensure that emissions
were consistent and that th ere were no missing sources.

3. Tier comparisons (by pollutant) were deve loped between the revised 2002 base year inventory and the initial base year inventory.

4. Data product summaries were provided to both the VISTAS Emission Inventory
Technical Advisor and to Mobile Source SIWG representatives for review and comment. Changes based on these comments were implemented in the files.

5. Version numbering was used for all i nventory files developed. The version numbering process used a decimal system to track major and minor changes. For example, a major change would result in a version going from 1.0 to 2.0. A minor change would cause a version number to go from 1.0 to 1.1. Minor changes resulting from largely editorial changes would result in a change from 1.00 to 1.01.

# 2.0 Projection Inventory Development

2.1 Point Sources

We used different approaches for differen t sectors of the point source inventory:

 For the EGUs, VISTAS relied primar ily on the Integrated Planning Model ® 

## (IPM ® 

## ) to project future generation as well as to calcu late 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, we used recently updated growth and control data consistent with the data used in EPA’s CAIR analyses, and supplemented these data with available S/L agency knowledge of planned emission controls or other changes at specific non-EGUs and updated fuel use forecast data for the U.S. Department of Energy.

For both sectors, we generated 2009 and 2018 inve ntories for a combined on-the-books (OTB) and on-the-way (OTW) control scenario. The OTB/OTW control scenario accounts for post2002 emission reductions from promulgated and pr oposed non-EGU federal control programs as of July 1, 2004; the final Clean Ai r Interstate Rule (CAIR); and St ate, local, and site-specific control programs as of Oct ober 1, 2007. Section 2.1.1 discusses the EGU projection inventory development, while Section 2.1.2 discusses the non-EGU projection inventory development.

2.1.1 EGU Emission Projections
The following subsections discuss the following specific aspects of the development of the EGU projections. First, we present a chronology of the EGU development process and discuss key decisions in selecting the fina l methods for performing the em issions projecti ons. Next, we describe the development of the final set of IP M runs that are included in the VISTAS Base G inventory. Next, we describe the process of transforming the IPM parsed files into NIF format. Fourth, we discuss the process for ensuring th at units accounted for in IPM were not doublecounted in the non-EGU inventor y. Fifth, we describe the QA/Q C checks that were made to ensure that the IPM results were properly inco rporated into the VIST AS inventory. Sixth, we document the changes to the IPM results that S/L agencies specified they wanted included in the VISTAS inventory based on new information that were not accounted for in the IPM runs. Finally, we present summaries of the B&F pr ojected EGU emissions by year, state, and pollutant.

2.1.1.1 Chronology of the Development of EGU Projections
At the beginning of the EGU i nventory development process, VI STAS considered three options for developing the VISTAS 2009 and 2018 projection inventories for EGUs:

### Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

### 92 

##  Option 1 – Use the results of IPM modeling conducted in support of the proposed Clean Air Interstate Rule (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 and 2015, which VISTAS would use to represent projected emissions in 2009 and 2018 respectively.

 Option 2 – Use the VISTAS 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 (M RPO). These runs incorporated VISTAS specific unit and regulation modified parame ters, and generate results for 2009 and 2018 explicitly.

An additional consideration for each of the three options was the inclusion of emission projections developed by the S outhern Company specifically for their units. Southern Company is a super-regional company which owns EGUs in Alabama, Florida, Ge orgia, and Mississippi and participates in VISTAS as an industry st akeholder. Southern Company used their energy budget forecast to project net ge neration and heat input for ever y existing and future Southern Company EGU for the years 2009 and 2018. Furthe r documentation of how Southern Company generated the 2009/2018 inventory fo r their units can be found in Developing Southern Company Emissions and Flue Gas Characteristics fo r VISTAS Regional Haze Modeling (April 2005, presented at 14 th 

## 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 ru ns (Option 3) to re present the 2009 and 2018
EGU forecasts of emissions for the OTB and OT W cases. During the call, Alabama and Georgia specified that they did not wish to use Sout hern Company provided emissions forecasts of 2009 and 2018 to represent the sources in their States. Missi ssippi decided to u tilize the Southern Company projections to represent activity at Southern Company f acilities in Mississippi. After the call, Florida decided against using Southern Company provi ded emissions forecasts of 2009 and 2018 to represent the sources in their State. Thus, Southern Company data was used only for Southern Company units in Mississippi fo r both the Base F and Base G projections.

The Option 3 IPM modeling resulted from a jo int 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} Grow th Modeling Method Task 2 Evaluation , February 11, 2004). Although IPM results were available from EPA’s modeling to su pport their rulemaking for the Clean Air Interstate Rule (CAIR), VISTAS stakeholders felt that certain model inputs needed to be improved. Thus, VISTAS and MRPO decided to hire contractors to conduct new IPM modeling and to post-process the IPM results. Southern Co mpany projections in 2009 were roughly comparable with IPM. For 2018, Southe rn Company projections were generally less than IPM because of assumptions made by Southern Company on which units would be
economical to control and incorrect data in the NEEDS database which feeds IPM.

In August 2004, VISTAS contracted with ICF Intern ational, Inc., to run IPM to provide utility
forecasts for 2009 and 2018 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 (as known at the time the run was made), including those that come into force in the study horizon. The CAIR Case is the Base Case w ith the proposed CAIR rule superimposed. The run results were parsed at th e unit level for the 2009 and 2018 run years. Also in August 2004, MRPO contracted with E.H. Pechan to post-pr ocess the IPM outputs gene rated by ICF to provide model-ready emission files. The IPM output f iles were delivered by ICF to VISTAS in November ( Future Year Electricity Generating Sect or Emission Inventory Development Using the Integrated Planning Model (IPM ® 

## ) in Support of Fine Par ticulate Mass and Visibility Modeling in the VISTAS and Midwest RPO Regions , January 2005), and the post-processed data files were delivered by Pechan to the MRPO in December 2004 ( LADCO IPM Model Parsed File Post-Processing Methodol ogy and File Preparation , February 8, 2005).

On March 10, 2005, EPA issued the final Clean Air Interstate Rule. VISTAS and MRPO, in conjunction with other RPOs, conducted anot her 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 comme nts. Several conference calls were conducted in the spring of 2005 to discuss and provide co mments on IPM assumptions related to six main topics: power system operation, generating res ources, emission control technologies, set-up parameters and rule, financial assumptions, a nd fuel assumptions. Based on these discussions, VISTAS sponsored a new set of IPM runs to re flect the final CAIR requirements as well as certain changes to IPM assumptions that were ag reed to by the VISTAS states. This set of IPM
runs is documented in Future Year Electricity Genera ting Sector Emission Inventory Development Using the Integrated Planning Model (IPM ® 

## ) in Support of Fine Particulate Mass and Visibility Modeling in the VISTAS and Midwest RPO Regions , April 2005 (these runs are referred to as the VISTAS Phase I analysis).

## Further refinements to the IPM inputs and a ssumptions were made by the RPOs, and ICF performed the following four runs using IPM dur ing the summer of 2005 (t hese runs are referred to as the VISTAS/CENRAP Phase II analysis):

 Base Case with EPA 2.1.9 coal, gas and oil price assumptions.

 Base Case with EPA 2.1.9 coal and gas suppl y curves adjusted for AEO 2005 reference case price and volume relationships.

 Strategy Case with EPA 2.1.9 coal, gas and oil price assumptions.

 Strategy Case with EPA 2.1.9 coal and gas supply curves adjusted for AEO 2005 reference case price and volume relationships.

The above runs were parsed for 2009 and 2018 run years. The above four runs were based on VISTAS Phase I and the EPA 2.1.9 assumptions. Th e changes that were implemented in the
above four runs are summarized below:

 Unadjusted AEO 2005 electricity demand projec tions were incorpor ated in the above
four runs.

 The gas supply curves were adjusted fo r AEO 2005 reference case price and volume relationships. The EPA 2.1.9 gas supply curves were scaled such th at IPM will solve for AEO 2005 gas prices when the power sector ga s demand in IPM is consistent with AEO 2005 power sector gas demand projections.

 The coal supply curves used in EPA 2.1.9 were scaled in such a manner that the average mine mouth coal prices that the IPM is solv ing in aggregated coal supply regions are comparable to AEO 2005. Due to the fact that the coal grades and supply regions between AEO 2005 and the EPA 2.1.9 are not directly comparable, this was an approximate approach and had to be perf ormed in an iterative fashion. The coal transportation matrix was not updated with EIA assumptions due to significant
differences between the EPA 2.1.9 and EI A AEO 2005 coal supply and coal demand region configurations.

##  The extensive NEEDS comments provided by VISTAS, MRPO, CENRAP and MANEVU were incorporated into the VISTAS Phase I NEEDS.

 MANE-VU’s comments in regards to the st ate regulations in the northeast were incorporated.

 Renewable Portfolio Standards (RPS) in the northeast was modeled based on the Regional Greenhouse Gas Initiativ e analysis. A single RPS cap was modeled for MA, RI, NY, NJ, MD and CT. These states could buy credits from NY, PJM and New England model regions.

 The investments required under the Illin ois power, Mirant and First Energy NSR settlements were incorpor ated in the above runs.

For the VISTAS/CENRAP Phase II se t 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 s econd file contains just the fo ssil-fuel burning units (e.g., emissions from biomass and landfill gas are omit ted). The RPOs decided to use the fossil-only file for modeling to be consistent with EPA, since EPA used the fossil only results for CAIR analyses. For the 10 VISTAS states, non-fossil fu els accounted for only 0.13 percent of the NOx emissions and 0.04 percent of the SO 2 

## emissions in the 2009 IPM runs.

S/L agencies reviewed the results of the VIST AS/CENRAP Phase II set of IPM runs, which were incorporated into the VISTAS Base F inventory. S/L agen cies primarily reviewed and
commented on the IPM results with respect to IPM decisions on NO x 

## post-combustion controls
and SO 2 

## scrubbers. S/L agencies provided the late st information on when and where new SO 2 

## and NO x 

## controls are planned to come online. S/L agencies also reviewed the IPM results to verify that existing controls and emission rates were properly reflected in the IPM runs. As directed by the S/L agencies, adjustments to the IP M results were made to specific units with any new information they had as part of the permitting process or other contact with the industry that
indicates which units will instal l controls as a result of CAIR and when these new controls will come on-line. Mississippi decided to continue to use the Southern Company projections instead of the IPM projections to repres ent emissions at Southern Comp any facilities in Mississippi. The initial set of state-specified changes to the VI STAS/CENRAP Phase II set of IPM runs were used to create the Base G projec tion inventory (and are documente d later in Section 2.1.1.6). The second set of state specified changes were made only for the 2018 inventory, resulting in the Base G2 2018 inventory (documented later in Se ction 2.1.1.7). The final set of state specified changes applied to both the 2009 and 2018 invent ories and were used to create the B&F 2009 and 2018 inventories (documente d later in Section 2.1.1.8).

## 2.1.1.2 VISTAS IPM runs for EGU sources
The following general summary of the VISTAS 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 Midwest RPO Regions , April 2005. The ICF documentation is to be used as an extension to EPA's proposed CAIR mode ling 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, el ectricity dispatch, and emission control strategies for meeting energy demand and environmental, transmission, dispatch, and reliability constraints.” The underlying database in this modeling is U.S. EPA’s National Electric Energy Data System (NEEDS) released with th e CAIR Notice of Data Availability (NODA). The NEEDS database contains the existing a nd planned/committed unit data in EPA modeling applications of IPM. NEEDS includes basic geog raphic, operating, air em issions, and other data on these generating units. VISTAS States and stakeholders provided changes for:

 NO x 

## post-combustion cont rol on existing units

 SO 2 

## scrubbers on existing units

 SO 2 

## emission limitations

 PM controls on existing units

 Summer net dependable capacity

 Heat rate for existing units

 SO 2 

## and NO x 

## control plans based on State ru les or enforcement settlements

The years 2009 and 2018 were explicitly modeled.

2.1.1.3 Post-Processing of IPM Parsed Files
The following summary of the VISTAS/Midwest Regional Planning Organization (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 postprocessing methodology is to take an initial IP M model output file and transform it into air quality model input files. ICF via VISTAS/MRPO provides an initial spre adsheet file containing
unit-level records of both

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

All records have unit an d fuel type data; exis ting, retrofit (for SO 2 

## and NO x 

## ), and separate NO x 

## control information; annual SO 2 

## and NO x 

## emissions and heat input; summer season (MaySeptember) NO x

## nameplate capacity megawatt (MW), and State FIPS code. Existing units al so have county FIPS code, a unique plant identifier (ORISPL) and unit ID (also called boiler ID) (BLRID); generic
units do not have these data. Th e processing includes estimating va rious types of emissions and adding in control efficiencies, stack paramete rs, latitude-longitude co ordinates, and State identifiers (plant ID, point ID, st ack ID, process ID). Additionally, the generic units are sited in a county and given appropriate IDs. This proce ssing is described in more detail below.

The data are prepared by transforming the generi c 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 cap acity, are provided a dummy OR IS 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 atta inment/nonattainment status. Within a State, plants (in county then ORIS plant code order) in attain ment counties are used first as sister sites to generic units, followed by plants in PM nonattain ment counties, followed by plants in 8-hour
ozone nonattainment counties. Note that no LADCO or VISTAS Stat es provided blackout counties that would not be considered when siting generics, so this process is identical to the one used for EPA 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 assi gned, first using the EPA-provided data files, secondly using the September 17, 2004 Pechan in-house la titude-longitude file, and la stly using county centroids. These data were only used when the data we re not provided in the 2002 NIF files. Stack parameters were attached, first using the EPA- 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 EPA 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 PM 10 

## and PM2.5, PM condensable, and NH 3 

## emissions for all units. Thus, ash a nd 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 obtai ned from the 2002 EGU NEI that were based on 2002 EIA-767
control data and the PM Calculat or program (a default of 99.2 percent is used for coal units if necessary); fuel use was back calculated from th e given heat input and a default SCC-based heat content; and emission factors were obtained from an EPA-approved October 7, 2004 Pechan
emission factor file based on AP-42 emission factor s. Note that this update d file is not the one used for estimating emissions for previous EP A post-processed IPM files. Emissions for 28 temporal-pollutant combinations were estimate d since there are seven pollutants (VOC, CO, primary PM 10 

## and PM 2.5 

## , NH 3 

## , SO 2 

## and NO x 

## ) and four temporal periods (annual, summer season, winter season, July day).

# The next step was to match the IPM unit IDs wi th the identifiers in VISTAS 2002 inventory. A
crosswalk file was used to obtain FIPS State an d 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-processe d files in NIF 3.0 format. Two sets of tables were developed :
“NIF files” for IPM units that have a crosswalk match and ar e 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 crossw alk match as well as generic units).

For Base F and Base G projections , VISTAS reviewed the PM and NH 3 

# emissions from EGUs as provided by Pechan and identified significan tly higher emissions in 2009/2018 than in 2002.
VISTAS determined that Pechan used a set of PM and NH 3 

# emission factors that are “the most recent EPA approved uncontrolled emission fact ors” for estimating 2009/2018 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 doma in. Thus, the emission increase from 2002 to 2009/2018 was simply an artifact of the change in emission factor, not anything to do with changes in activity or control technology application. Also, VIST AS identified an inconsistent use of SCCs for determining emission fact ors between the base and future years.

VISTAS resolution of the PM and NH 3 

# 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. The first step was the adjustment of the 2002 base year emissions inventory. Using the latest “EPA-approved” uncontrolled emission factors by SCC, Alpine Geophysics utilized CERR or VISTAS 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 NH 3 

# ) only. For PM emissions, the cond ensable component of emissions was calculated and added to the resulting PM pr imary 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. Alpi ne Geophysics updated the SCCs in the future year inventor y to assign the same base year SCC. Using the same methods as described for the 2002 revisions, those non-IPM ge nerated pollutants were estimated using IPM predicted fuel characteristics a nd base year 2002 SCC assignments.

2.1.1.4 Eliminating Double Counting of EGU Units
The following procedures were used to avoi d double counting of EGU emissions in the 2009/2018 point source inventory. The 2002 VISTAS poi nt source emission inventory contains
both EGUs and non-EGUs. Since this file cont ains both EGUs and non-EGU point sources, and

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

## 99 

# EGU emissions are projected using the IPM, it wa s necessary to split the 2002 point source file into two components. The first component cont ains those emission units accounted for in the IPM forecasts. The second component contains all other point sources not accounted for in IPM.

As described in the previous section, Pechan developed 2009/2018 NIF files for EGUs from the IPM parsed files. All IPM matched units were initially removed from the 2009/2018 point source inventory to create the non- EGU inventory (which was projected to 2009/2018 using the nonEGU growth and control factors described in Section 2.1.2). This was done on a unit-by-unit
basis based on a cross-reference table that matc hes IPM emission unit identifiers (ORISPL plant code and BLRID emission unit code) to VISTAS NIF emission unit identifiers (FIPSST state code, FIPSCNTY county code, State Plant ID, Stat e Point ID). When there was a match between
the IPM ORISPL/BLRID and the VISTAS emissi on unit ID, the unit was assigned to the EGU inventory; all other emission units we re assigned to the non-EGU inventory.

If an emission unit was contained in the NIF f iles created by Pechan fr om the IPM output, the corresponding unit was removed from the in itial 2009/2018 point source inventory. The NIF 2009/2018 EGU files from the IPM parsed files were then merged with the non-EGU 2009/2018
files to create the 2009/2018 Ba se F point source files.

Next, we prepared several ad-hoc QA/QC queries to verify that there was no double-counting of
emissions in the EGU a nd non-EGU inventories:

 We reviewed the IPM parsed files {VIS TASII_PC_1f_AllUnits_2009 (To Client).xls and VISTASII_PC_1f_AllUnits_2018 (To Client).xls} to identify EGUs accounted for in IPM. We compared this list of emission units to the non-EGU inventory derived from the VISTAS cross-reference table to verify thatunits accounted for in IPM were not doublecounted in the non-EGU invent ory. As a result of this comparison, we made a few adjustments in the cross-reference table to a dd emission units for four plants to ensure these units accounted for in IPM were moved to the EGU inventory.

 We reviewed the non-EGU inventory to identify remaining emission units with an Standard Industrial Classification (SIC) code of “4911 Electrical Services” or Source Classification Code of “1-01-xxx-xx External Combustion Boiler, Electric Generation”. We compared the list of sources meeting these selection criteria to the IPM parsed file to
ensure that these units were not double-counted.

S/L agencies also reviewed the 2009/2018 point source inventory to verify whether there was any double counting of EGU emissions. In two in stances, S/L agencies provided corrections
where an emission unit was double counted.

# 2.1.1.5 Quality Assurance Steps
Quality assurance was an important component to the inventory development process. The following QA steps on the EGU component of th e VISTAS revised 2009/2018 EGU inventory:

1. Provided parsed files (i.e., Excel spreadsheets that provide un it-level results derived from the model plant projections obtained by the IP M) to the VISTAS EGU SIWG for review.

2. Provided facility level emission summar ies for 2009/2018 for both the base case and
CAIR case to the VISTAS EGU SIWG to ensure that emissions were consistent and that there were no missing sources.

3. Compared, at the State-level, emissions from the IPM parsed files and the post-processed NIF files to verify that the post-processed NIF files were consistent with the IPM parsed
file results.
VISTAS requested S/L review of th ese files – the changes specified by states as a result of this review are documented in the following subsection.

2.1.1.6 S/L Adjustments to IPM Modeling Results for Base G Projections
After S/L agency review of the final set of IPM ru ns (as incorporated into the Base F inventory), 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 subtrac tion future emission cont rols based on the best available data from state rules, enforcemen t agreements, compliance plans, permits, and discussions/commitments from individual companies.

For example, Dominion Virginia Power released their company-wide plan to reduce emission to meet the requirements of CAIR and other programs . This plan varies substantially from the IPM
results both in terms current and future controls and timing of these controls. As a result, VA DEQ developed their best estimates of future c ontrols on EGUs in Virginia. Also, Duke Energy and Progress Energy have updated their plans for complying with North Carolina’s Clean Smokestack Act. These plans vary substantially from the IPM results both in terms current and future controls and timing of these controls. As a result, NC DENR replaced the IPM emission projections for 2009 with projec tions from the Duke Energy and Progress Energy compliance plan. NC DENR elected to use the IPM results for 2018.

Some S/L agencies specified changes to the c ontrols assigned by IPM to reflect their best estimates of emission controls. These changes involved either 1) addi ng selective catalytic reduction (SCR) or scrubber controls to units where IPM did not predict SCR or scrubber controls, or 2) removing IPM-assi gned SCR or scrubber controls at units where the S/L agency indicated their were no firm plans for controls at those units. We generally used a control

# efficiency of 90 percent when adding or removing SO 2 

# scrubber controls (unless a different control efficiency was provided by the State). We generally used a control efficiency of 90 percent when adding or removing NO x 

# SCR controls at coal-fired plants, 80 percent when adding or removing NO x 

# SCR controls at gas-fired plants, a nd 35 percent when adding or removing NO x 

# SNCR controls (unless a different control efficiency was provid ed by the State). The changes specified by the S/L agencies are summarized in Table 2.1-1. A comparison of the IPM and VISTAS control assumptions fo r all coal-fired EGUs in the Base G/G2 inventories are summarized in Appendix H. In addition to the changes to the IPM-assi gned controls, the S/L agencies also specified other types of changes to the IPM results. These ot her specific changes to
the IPM results are summarized in Table 2.1-2.

S/L agencies provided informati on and/or comment on changes in stack parameters from the 2002 inventory for 2009/2018 inventory. Changes to st ack parameters were also made in cases
where new controls are scheduled to be installed. In cases wher e an emission unit projected to
have a SO 2 

# scrubber in either 2009 or 2018, 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 or 2018 ar e 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 th e stack exit temperature to 169 degrees F (this is the virtual temperature derived from a wet temp erature 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.

2.1.1.7 S/L Adjustments to IPM Modeling Resu lts for Base G2 2018 Projections
Following release of the Base G inventory, four States specified additional changes to reflect
their best estimates of emission controls in 2018. These additional changes are marked with an “*” in Tables 2.1-1 and 2.1-2. The following cha nges were requested and implemented in the
VISTAS 2018 Base G2 EGU emissi ons and modeling inventories:

 

# Florida - Removed scrubbers from Smith units 1 & 2. Added scrubbers to Crist units 4, 5, & 6. Forecast emissions (from 2002 base) using growth factors for Northside units 1A and 2A. These units were estimated to be non operational in the IPM base case run.

 

# Georgia - Added scrubbers to Plant Sc herer (Units 1-4) and Pl ant Yates (Units 6 & 7).

 

# North Carolina - Remove scrubber from F Lee unit 3.

 

# West Virginia - Pleasants Units 1 and 2 had SO2 em issions reduced to account for the facility's inclusion of previously bypassed 15% effluent stream to the scrubber and the control efficiency and emissions will refl ect a change from 79.9% to 95% control.Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission InventoriesMACTEC, Inc.102Table 2.1-1 Adjustments to IPM Control Determinations Specified by S/L Agenciesfor the Base G/G2 2009/2018 EGU Inventories.NOxRetrofit Emission ControlsSO2Retrofit Emission ControlsStatePlant Name and IDUnit2009201820092018IPMStateIPMStateIPMStateIPMStateAL James H.

# 2.1.1.8 S/L Adjustments to IPM Modeling Results for B&F Projections
For the B&F inventory, the S/L agencies were asked to review the Base G2 inventory with respect to the following items:

 Identify any updates needed to better reflect current information on when and where
future controls would occur based on the best available data from state rules, enforcement agreements, compliance plans, permits, and discussions/commitments from individual companies;

 Identify any updates needed to change the IPM determination that most oil/gas steam units would either retire early or have no operation in 2009 or 2018; and

 Identify any updates needed to change the IPM assignment and VISTAS post-processing of generic units with specif ic information on new capacity.
The changes specified by the S/L agencies are summarized in Table 2.1- 3. A comparison of the IPM and VISTAS control assumptions for all co al-fired EGUs in the B&F inventories are summarized in Appendix I.

# 2.1.2 Non-EGU Emission Projections
The general approach for assembling future year data was to use growth and control data
consistent with the data used in EPA’s Clean Ai r Interstate Rule analyses, supplement these data with available stakeholder input, and provide the results for stakeholder review to ensure credibility. We used the revised 2002 VISTAS base year inventory, based on the 2002 CERR submittals as the starting point for the non-EGU pr ojection inventories. As described in Section 2.1.1.4, we split the point source inventory in to EGU and non-EGU components. MACTEC performed the following activitie s to apply growth and control factors to the 2002 inventory to generate the 2009 and 2018 pr ojection inventories:

 Obtained, reviewed, and applied the most current growth factors developed by EPA, based on forecasts from an updated Regi onal 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-sp ecific or sector-specific growth factors submitted by stakeholders;

 Obtained and incorporated information regard ing sources that have shut down after 2002 and set the emissions to zero in the projection inventories;

 Obtained, reviewed, and applied control assumptions for programs “on-the-books” and “on-the-way”;

 Provided data files in NIF3.0 format and emission summaries in EXCEL format for review and comment; and

 Updated the database with corrections or ne w information from S/L agencies based on their review of the Base F 2009/2018 inventories.
The following sections discu ss each of these steps.

2.1.2.1 Growth assumptions for non-EGU sources
This section describes the growth factor data used in develo ping the Base F inventory for 2009 and 2018, as well as the changes to the growth factor data made for the Base G inventory.

The growth factor data used in developing the Base F inventory were consistent with EPA’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). Thre e sources of data were used in developing the growth f actors for the Base F inventory:

 State-specific growth rates from the Re gional 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 indus try sector, population, farm sector value

# added, and gasoline and oil expenditures) ar e available by 4-digit SIC code at the
State level.

 Energy consumption data from the DOE’s Energy Information Administration’s (EIA) Annual Energy Outlook 2004, w ith 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 ma pped to specific SCCs for the non-EGU fuel use sectors (e.g., commercial coal, industria l natural gas). Growth factors for the residential natural gas combustion category, fo r 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 Atla ntic division includes eight
southeastern States and the District of Columbia). Alt hough one would expect different growth rates in each of these States due to unique demographic and socioeconomic trends, EIA’s projects all States within each division using the same growth rate.

 Specific changes for sectors (e.g., plastics, synthetic rubber, carbon black, cement manufacturing, primary metals, fabricated me tals, motor vehicles and equipment) where
the REMI-based rates were unrealistic or hi ghly uncertain. Growth projections for these sectors were based on industry group forecas ts, Bureau of Labor Statistics (BLS) projections and Bureau of Ec onomic Analysis (BEA) histor ical growth from 1987-2002.

In addition to the growth data described above, we received two sets of growth projections from
VISTAS stakeholders.

The American Forest and Paper Association (A F&PA) supplied growth projections for the pulp and paper sector, which were applied to SIC 26xx Paper and Allied Products. The AF&PA projection factors are for the U.S. industry and apply to all States equally. The numbers come from the 15-year forecast for world pulp and recovered paper prepared by Resource Information Systems Inc. (RISI).

AF&PA Growth Factor SIC Code Sector 2002 to 2009 2002 to 2018

2611 Pulp Mills 1.067 1.169
2621 Paper Mills 1.067 1.169
2631 Paperboard Mills 1.067 1.169



# For both the Base F and Base G inventories, we used the above AF&PA growth factors by SIC
instead of the factors obtained from EPA’s CAIR analysis.

# For the Base F inventory, the NCDENR supplie d recent projections for three key sectors in North Carolina where declining production wa s anticipated – SIC 22xx Textile Mill Products, 23xx Apparel and Other Fabrics, and 25xx Furniture and Fixtures. For th e Base G inventory, NCDENR decided to use a gr owth factor of 1.0 for thes e SIC codes for both 2009 and 2018. Although NCDENR has data that shows a steady decline in these industries in NC, NCDENR
wanted to maintain the emission levels at 2002 le vels so the future emission reduction credits were available in the event that they are need ed for nonattainment areas. The specific growth
factors for these industrial se ctors in North Carolina were:

NCDENR Growth Factors for Specific Industrial Sectors

2009 2018 SIC Code Industrial Sector Base F Base G Base F Base G

22xx Textile Mill Products 0.6239 1.00 0.2792 1.00

23xx Apparel and Other Fabrics 0.5867 1.00 0.2247 1.00

25xx Furniture and Fixtures 0.8970 1.00 0.7647 1.00



# For the Base G inventory, we ma de one additional change to th e growth factors. The Base F inventory relied on DOE’s AEO2004 forecasts for projecting emissions fo r fuel-burning SCCs (applies mainly to ICI boilers 1-02-xxx-xx and 1- 03-xxx-xx, as well as in-process fuel use). We replaced the AEO2004 data with the more recent AEO2006 forecas ts (released in February 2006) to reflect changes in the energy market and to improve the emissions growth factors produced. We obtained the corresponding AEO 2006 projection tables from DOE’s web site
located at http://www.eia.doe.gov/oiaf/aeo/supplement/supref.html 

# . We developed tables comparing the growth factors based on AEO2004 and AEO2 006. These comparison tables were reviewed by the S/L agencies. Based on this review, VIST AS decided to use the AEO2006 growth factors for fuel burning SCCs.

We used the EPA’s EGAS model and updated th e corresponding AEO2006 projection tables to create growth factors by SCC. We applied the updated growth factors to 2002 actual emissions and replaced the 2009 and 2018 emissions in NIF EM tables for the affected SCCs.

# 2.1.2.3 Control Programs applied to non-EGU sources
We used the same control programs for bot h the 2009 and 2018 non-EGU point inventory. Two control scenarios were develope d: on-the-books (OTB) controls and on-the-way (OTW) controls. The OTB control scenario accounts for post-2002 em ission reductions from promulgated federal, State, local, and site-specific control programs. The OTW contro l scenario accounts for proposed (but not final) control programs that are reas onably anticipated to re sult 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.

# September), we calculated annual emissions by mu ltiplying the 5-month allowances by a factor of 12 divided by 5.

2.1.2.3.2 OTB - Industrial Boiler/Process Heater MACT



# EPA anticipates reductions in PM and SO 2 

# as a result of the Industr ial 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 grea ter than 10 mmBtu/hr. EPA prepared a list of
SCCs for solid fuel industrial and commercial/ institutional boilers and process heaters. We identified boilers greater than 10 mmBtu/hr usin g 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 EPA for assigning default capaciti es based on SCC. The applied MACT control efficiencies were 4 percent for SO 2 

# and 40 for percent for PM 10 

# and PM2.5 to account for the cobenefit from installati on of acid gas scrubbers and other co ntrol equipment to reduce HAPs. On June 8, 2007, the U.S. Court of Appeals for the District of Columbia Circuit vacated and remanded the NESHAP for Industrial, Commercial and Institutional Boilers and Process Heaters.
VISTAS States decided to leave the emission re ductions in place since they envision using a 112(j) strategy (e.g., the “MACT hammer”) to obtain similar levels of control)

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



# Maximum achievable control technology (MACT) requirement s 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 em ission reductions were designed from Federal Register (FR) notices and discussions with EP A’s Emission Standards Division (ESD) staff. We did not apply reductions for MACT standards with an initial comp liance 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.

2.1.2.3.4 OTB Combustion Turbine MACT



# The projection inventories do not include the NO x 

# co-benefit effects of the MACT regulations for Gas Turbines or stationary Reciprocating In ternal Combustion Engines, which EPA estimates to be small compared to the overall inventory.

2.1.2.3.5 OTB - Petroleum Refinery Initiative (MS and WV)



# Three refineries in the VISTAS region ar e affected by two October 2003 Clean Air Act settlements under the EPA Petroleum Refinery Initi ative. The refineries are: (1) the Chevron

# refinery in Pascagoula, MS; (2) the Ergon refinery in Vicksburg, MS; and (3) the Ergon refinery in Newell, WV.

The first consent decree pertained to Chevr on refineries in Rich mond and El Segundo, CA; Pascagoula, MS; Salt Lake City, UT; and Kapol ei, HI. Actions required under the Consent
Decree will reduce annual emissions of NO x 

# by 3,300 tons and SO 2 

# by 6,300 tons. The consent decree requires a pr ogram to reduce NO x 

# emissions from refinery heaters and boilers through the
installation of NO x 

# controls that meet at least an SNCR le vel of control. The refineries are to eliminate fuel oil burning in any combustion unit. The consent decree also requires reductions of
NO x 

# and SO 2 

# from the fluid catalytic cracking unit and control of acid gas flaring incidents. The consent decree does not provide sufficient inform ation to calculate emission reductions for the FCCU or flaring at the Pascagoula refinery. Ther efore, we calculated a general percent reduction
for NO x 

# and SO 2 

# by dividing the expected emission reducti ons at the five Chevron refineries by
the total emissions from these five refineries (as reported in the 1999 NE I). This resulted in applying percent reductions of 45 percent for SO 2 

# and 28 percent for NO x 

# to FCCU and flaring emissions at the Chevron Pascagoula refinery.

The second consent decree pertained to the Erg on-West Virginia refinery in Newell, WV; and the Ergon Refining facility in Vi cksburg, MS. The consen t decree requires the two facilities to implement a 6-year program to reduce NO x 

# emission from all heaters and boilers greater than 40 mmBtu/hr, and to eliminate fuel oil burning in any combustion unit (except during periods of natural gas curtailment). Specifically, ultra low NO x 

# burners are required on Boilers A and B at Newell, a low NO x 

# -equivalent level of control for heat er H-101 at Newell and heaters H-1 and H-3 at Vicksburg, and an ultra low NO x 

# burner level of control fo r heater H-451 at Vicksburg.

2.1.2.3.6 OTW - NO x 

## SIP Call (Phase II)



# The final Phase II NO x 

# SIP call rule was finalized on Ap ril 21, 2004. States had until April 21, 2005, to submit SIPs meeting the Phase II NO x 

# budget requirements. The Phase II rule applies to large IC engines, which are primarily used in pipeline transmission service at compressor
stations. We identified affect ed units using the same methodol ogy as was used by EPA 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 contro l level of 82 percent for natural gas-fired IC engines and 90 percent for diesel or dual fuel categories. As show n later in Table 2.1-12, several S/L agencies provided move specific information on the anticipated controls at the compressor
stations. This information was used in the Base G inventory instead of the default approach used by EPA in the proposed Phase II rule.

2.1.2.4 Quality Assurance steps
Final QA checks were run on the revised projecti on inventory data set to ensure that all corrections provided by the S/L agencies and stake holders were correctly incorporated into the
S/L inventories and that there we re no remaining QA issues that could be addressed during the duration of the project. After e xporting the inventory to ASCII te xt files in NIF 3.0, the EPA QA program was run on the ASCII files and the QA output was reviewed to verify that all QA issues
that could be addressed were resolved

Throughout the inventory developm ent process, quality assuran ce steps were performed to ensure that no double counting of emissions occurred, and to ensu re that a full and complete inventory was developed for VISTAS. Quality assurance was an important component to the inventory development process and MACTEC performed the following QA steps on the point source component of the VISTAS re vised 2002 base year inventory:

Facility level emission summaries were prepar ed and evaluated to ensure that emissions were consistent and reasonable. The su mmaries included base year 2002 emissions, 2009/2018 projected emissions accounting only for growth, 2009/2018 projected emissions accounting for both growth a nd emission reductions from OTB and OTW controls.
State-level non-EGU comparisons (by pollutant ) were developed for the base year 2002 emissions, 2009/2018 projected emissions accounting only for growth, 2009/2018 projected emissions accounting for both gr owth and emission reductions from OTB and OTW controls.
Data product summaries and raw NIF 3.0 data files were provided to the VISTAS Emission Inventory Technical Advisor and to the Point Source, EGU, and non-EGU Special Interest Work Group representati ves for review and comment. Changes based on these comments were reviewed and approved by the S/L point source contact prior to implementing the changes in the files.
Version numbering was used for all invent ory files developed. The version numbering process used a decimal system to track major and minor changes. For example, a major change would result in a versio n going from Base F1 to Base F2.

2.1.2.5 Additional Base G Updates and Corrections
Table 2.1-13 summarizes the updates and corrections to the Base F inventory that were requested by S/L agencies and incorporated in to the Base G 2009/2018 inventories.

# Table 2.1-13 Summary of Updates and Corrections Incorporated into the
Base G 2009/2018 Non-EGU Inventories.

State Nature of Update/Correction
AL Corrected the latitude and longitude for two facilities: Ergon Terminalling (Site ID: 01-073- 010730167) and Southern Power Franklin (Site ID: 01-081-0036).
Corrections to stack parameters at 10 facilities for stacks with parameters that do not appear to fall into the ranges typically termed "acceptable" for AQ modeling.

FL Corrected 2009/2018 emission values for the Miami Dade RRF facility (Site ID: 12-086-0250348) based on revised 2002 emissions and application of growth control factors for 2009/2018.
GA Hercules Incorporated (12-051-05100005) had an erroneous process id (#3) within emission unit id SB9 and was deleted. This removes about 6,000 tons of SO 2 

## from the 2009/2018 inventories.

Provided a revised file of location coordinates at the stack level that was used to replace the location coordinated in the ER file.
There are several sources that have updated their emissions from their BART eligible units. most of these changes were for fairly small (<50 tpy) sources.
NC Made several changes to Base F inve ntory to correct the following errors: 1. Corrected emissions at Hooker Furniture (Site ID: 37-081-3708100910), release point G-29, to use the corrected values in 2002 and carry those same numbers through to 2009 and 2018 since NCDENR assumes zero growth for furniture industry. 2. Identified many stack parameters in the ER file that were unrealistic. Several have zero for height, diameter, gas velocity, and flow rate. NC used the procedures outlined in Section 8 of the document ""National Emission Inventory QA and Augmentation Report" to correct unrealistic stack parameters. 3. Identified truncated latitude and longitude values in Base F inventory. NC updated all Title V facility latitude and longitude that was submitted to EPA for those facilities in 2004. Smaller facilities with only two decimal places were not corrected. 4. Corrected 2018 VOC emissions for International Paper (3709700045) Emission Unit ID, G-12, to reflect changes to the 2002 inventory.

There are three Transcontinental Natural Gas Pipeline facilities in NC that are subject to the NO x 

## SIP call. NCDENR took 2004 emissions and grew them to 2009 & 2018 and capped those units that are subject to the NO x 

## SIP Call Rule. These facility IDs are 37-057-3705700300, 37-097-3709700225, and 37-157-3715700131.
NCDENR applied NO x 

## RACT to a two facilities located in the Charlotte nonattainment area. NCDENR provided 2009 & 2018 emissions for Philip Morris USA (37-025-3702500048) and Norandal USA (37-159-3715900057).
SC Corrected PM species emission values. SC DHEC’s initial CERR submittal reported particulate matter emissions using the PM-FIL, PM 10 

## -FIL, and PM 2.5 

## -FIL pollutant codes. In August 2005, SC DHEC indicated that data reported using the PM-FIL, PM 10 

## -FIL, and PM 2.5 

## -FIL pollutant codes should actually have been reported using the PM-PRI, PM 10 

## -PRI, and PM 2.5 

## _PRI codes. MACTEC performed a subsequent PM augmentation in April 2006 using the revised pollutant codes. These changes were reflected in the Base G 2009/2018 emission inventory.
Specified that the Bowater Inc. facility (45-091-2440-0005) in York County conducted an expansion in 2003/2004 and plans a future expansion. SC provided updated emissions for 2009 and 2018 for this facility.

# Table 2.1-13. Continued.

State Nature of Update/Correction
TN Updated 2009/2018 emissions for Eastman Chemical (47-163-0003) based on final (Feb. 2005) BART rule.
Updated 2009/2018 emission inventory for the Bowater facility (47-107-0012) based on the facility’s updated 2002 emission inventory update.
Replaced 2009/2018 data from Hamilton County, Tennessee, usin g data from Hamilton County’s CERR submittal as contained in EPA’s 2002 NEI (in Base F, the inventory for Hamilton County was based on the draft VISTAS 2002 inventory, which in turn was based on the 1999 NEI); applied growth and control factors to revised 2002 inventory to generate emission projections for 2009/2018.
Updated 2009/2018 emissions for PCS Nitrogen Fe rtilizer LP (Site ID: 47- 157-00146) based on the facility’s updated 2002 emission inventory update.
The 2002 NEI correctly repor ts the actual emissions for CEMEX (47-093-0008) after the NO x 

## SIP call. There is no reason to suspect that that rate would change in 2008, 2009, or 2018. Emissions for 2009/2018 were set equal to 2002 emissions.
In the Base F 2009/2018 inventories, NO x 

## controls were applied for two units at Columbia Gulf Transmission (47-111-0004). There are no plans for controls at these units, EO3 and EO4. The assumed control efficiency of 82 percent was backed out in the 2009/2018 inventories.
VA VADEQ provided 2009/2018 NO x 

## emission estimates for NO x 

## Phase II gas transmission sources at three Transco facilities (51-011-00 011, 51-137-00027, 51-1 43-00120) which were used to replace the default NO x 

## Phase II control assumptions for these facilities.
VADEQ provided updated 2009/2018 NO x 

## and SO 2 

## emissions based on new controls required by a November 2005 permit modification and netting exercise. The entire power plant facility is limited to 213 tons of NO x 

## and 107 tons of SO 2 

## per year. The permit also allowed the installation of 3 new boilers, also under the 213 tons of NO x 

## /year cap.
WV Updated 2009/2018 emissions for Steel of West Virginia (Site ID: 54-011-0009) based on the facility’s updated 2002 emission inventory update.
Made changes to several Site ID names due to changes in ownership
Base F emissions were much too high for Weirton Steel (54-021-0029). WV believes that the source is very unlikely to emit the NO x 

## SIP Call budgeted amounts in 2009 or 2018. WV provided revised emission estimates based on EGAS for 2009/2018.
Made corrections to latitude/longitude and stack parameters at a few facilities for stacks with parameters that do not appear to fall into the ra nges typically termed "accep table" for AQ modeling.

State Nature of Update/Correction
AL Alabama suggest additional changes to the 2009 inventory resulting from their PM 2.5 

## modeling for the Birmingham area; however, these changes were identified too late to be incorporated in the VISTAS B&F inventory and ASIP modeling.
For 2018, incorporated emission changes due to BART controls at Exxon Mobil (Site ID: 01-053- 0007), International Paper (Site ID: 01-079-0001), and Solutia (Site ID: 01-103-0010). International Paper (Site ID: 01-079-0001) Unit 004 to be shutdown in the 2018 inventory.
FL For both 2009 and 2018, incorporated emission changes due to BART controls at Georgia Pacific (Site ID: 12-107-1070005) Unit 15.
MS For 2018 only, changed SO2 emission estimate for Pursue Energy (Site ID: 28-121-00036) based on the facility’s estimates of the gas reserve at the site.
For 2018 only, changed emission estimates for all po llutants at several emission units at the Chevron Pascagoula Refinery (Site ID: 28-059-00058) to reflect BART source reductions.
SC For both 2009 and 2018, identified 15 facilities that have permanently closed. Emissions from these facilities set to zero for all pollutants.
TN For both 2009 and 2018, identified seven facilities that have permanently closed. Emissions from these facilities were set to zero for all pollutants.
For both 2009 and 2018, identified three emission units that have permanently closed. Emissions from these units were set to zero for all pollutants. 47-009-0130-002 (APAC – TN, Inc.-Harrison Construction – Asphalt plant), 47-009-0130-003 (APAC – TN, Inc.-Harrison Construction – Asphalt crusher), and 47-139-0004-001 (Intertrade - Number 6 acid plant)
The following individual source will be shut down in 2010: 47-001-0020-002 (DOE, Y-12 – Boilers 1-4). For the 2018 inventory only, emissions from this unit were set to zero for all pollutants.
A portion of 47-163-0003-020101 (Eastman, B-83-1 Stoker Boilers). This source previously consisted of 14 boilers (Boilers 11-24). Boilers 11-17 have been removed from service. Emissions for both 2009 and 2018 were reduced by 26.64%, based on the portion of the heat input capacity that is being removed from service.
SO2 emissions in 2018 from 47-163-0003-021520 (Eastman, B-253-1 Tangential PC Boilers) were reduced by 90% to reflect anticipated BART controls.
Reduced SO2 emissions at 47-157-00475 (Lucite International) in Shelby County as a result of a consent decree w ith U.S. EPA.
VA Changed SO2 emissions in 2009 and 2018 for thir teen facilities to reflect updated information from VADEQ regarding projected SO2 controls.
WV Weirton Steel (54-029-00001) and Wheeling Pittsburgh Steel (54-009-00002) have undergone significant, permanent process changes since 2002. WV DEP staff have consulted with facility staff and determined that calendar year 2004 emissions re present a better basis for future year emissions estimates. Therefore, W VDEP compiled emissions data from the 2004 inventory for these sources and applied the most current VISTAS growth f actors to estimate emissions in 2009 and 2018.

# 2.2 Area Sources

This section describes the methodology used to develop the 2009 and 2018 projection Base F and Base G projection inventories. This section describes two a pproaches to these projections. Separate methods for projecting emissions were used for non-agricultural (stationary area) and agricultural area sources (predominantly NH 3 

# emissions). The two methods used for these
sectors are described in the sections that follow.

2.2.1 Stationary area sources
The general approach used to calculate Base F projected emissions for stationary area sources
was as follows:

1. Use the VISTAS Base F 2002 base year invent ory as the starting point for projections.

2. MACTEC then worked with the VISTAS Stat es (via the Stationary Area Source SIWG) to obtain any State specific growth factors and/or future controls from the States to use in developing the projections.

3. MACTEC then back calculated uncontrolled emissions from the Base F 2002 base year inventory based on existing controls reporte d in the 2002 Base F ba se year inventory.

4. Controls (including control efficiency, rule e ffectiveness and rule pe netration) provided by the States or originally developed for us e in estimating projected emissions for U.S. EPA’s Heavy Duty Diesel (HDD) rulemaking em ission projections and used in the Clean Air Interstate Rule (CAIR) projections were th en used to calculate controlled emissions. State submitted controls had precedence ove r the U.S. EPA developed controls.

5. Growth factors supplied from the States or the U.S. EPA’s CAIR emission projections were then applied to project the controlled emissions to th e appropriate year. In some cases EGAS Version 5 growth factors were us ed if no growth factor was available from either the States or the CAIR growth factor files. The use of E GAS Version 5 growth factors was on a case-by-case basis wherever State-supplied or CAIR factors were not
available for SCCs found in the 2002 Base F inventory. Use of the EGAS factors was
necessitated due to the CERR submittals used in constructing the Base F 2002 inventory.
Use of the CERR data resulted in SCCs that were not found in the CAIR inventory and if no State-supplied growth factor was provided required the use of an EGAS growth factor.

6. MACTEC then provided the final draft Base F projection inventory for review and comment by the VISTAS States.

For Base F stationary area sources, no State-s upplied growth or contro l factors were provided.
Thus for all of the sources in this sector of th e inventory, growth and controls for Base F were

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 134 

# applied based on controls initially identified for the CAIR and growth factors identified for the CAIR projections.

For the Base G projections, the Base G 2002 base year inventory (see section 1.2.3) was used as a starting point. States provided some updated fu ture controls but growth factors used were
identical to those used for Base F. The revised controls for Base G were largely for new sources added as part of the 2002 Base F comments. The calculation of Base G pr ojections was identical to the six steps outlined above with the exception of revisions made to prescribed fire for 2009
and 2018 and for the State of North Carolina. North Carolina provided 2009 and 2018 updated emission files used to update the emissions for each year for several s ource categories. However not all sources in the inventory were included in these NC updates. As a consequence, the final Base G 2009 and 2018 inventory for NC included em issions updated using the NC supplied files and emissions developed using growth and control factors as outlined above.

In a few cases, additional growth factors had to be added for source ca tegories that had not initially been included in the Base F inventory. These growth factors were obtained from EGAS 5.0. Finally updates to growth fact ors 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 us ed to reflect changes in energy efficiency resulting from new or updated fuel firing technologies.

2.2.1.1 Stationary area source controls
The controls obtained by MAC TEC for the HDD rulemaking were controls for the years 2007, 2020, and 2030. Since MACTEC was preparing 2009 and 2018 projections, control values for intermediate years were prepared using a straight lin e interpolation of c ontrol level between 2007 and 2020. The equation used to calculat e the control level was as follows:

CE = (((2020 CE – 2007 CE)/13)*YRS) + 2007 CE

Where:

CE = Control Efficiency for either 2009 or 2018

2020 CE = HDD Control Efficiency value for 2020

2007 CE = HDD Control Efficiency value for 2007

13 = Number of years between 2020 and 2007

YRS = Number of years beyond 2007 to VISTAS Projection year

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 135 

# For 2009 the value of YRS would be two (2) and for 2018 the value would be eleven (11). Control efficiency values were determined for VOC, CO and PM. Rule penetration values for each year in the HDD controls tables obtained by MACTEC were always 100 percent so those values were maintained for the VISTAS projections.

Prior to performing the linear interpolation of the controls, MACTEC evaluated controls from the CAIR projections (NOTE: Initially the cont rols came from the IAQTR projections, however the controls used in CAIR were virtually identi cal to those in IAQTR). Those controls appeared
to be identical to those used for the HDD rulemaking. In addition, MACTEC received some
additional information on some controls for ar ea source solvents (email from Jim Wilson, E.H. Pechan and Associates, Inc. to Gregory Stella , VISTAS Emission Inventory Technical Advisor, 3/5/04) that were used to check against the controls in the HDD rulemaking files. Where those controls proved to be more stringent than th e HDD values, MACTEC updated the control file with those values (which were then used in the interpolation to develop 2009 and 2018 values). Finally, for VOC the HDD controls were initia lly provided at the State-county-SCC level. However, upon direction from the VISTAS Emi ssion Inventory Technical advisor, the VOC
controls were consolidated at the SCC level a nd applied across all counties within the VISTAS region (email from Gregory Stella, Alpine Geophysic s, 3/3/2004) to ensure that no controls were missed due to changes in county FIPS codes and/or SCC designations between the time the HDD controls were developed and 2002.

The equation below indicates how VOC emissions we re projected for stationary area sources.

# In the pre-Base F 2018 emission estimates, an en ergy efficiency factor was applied to energy related stationary area sources. The energy effici ency factor was applied along with the growth factor to account for both growth and changes in energy efficiency. That factor was not applied to the Base F projections since information s upplied by U.S. EPA related to the CAIR growth factors indicated that growth values for those ca tegories were derived from U.S. Department of Energy (DOE) and were felt to account for change s in growth and projected energy efficiency. For the Base G inventory, these energy effici ency factors were re-instituted and used in conjunction with EGAS 5.0 growth f actors in a manner identical to that used for the pre-Base F inventories. The energy effici ency factors were derived from U.S. DOE’s Annual Energy Outlook report.

One significant difference between the Base F a nd Base G control factors was for counties and independent cities in northern Virginia. Several counties and i ndependent cities in northern Virginia are subject to Ozone Transport Commis sion rules. For these counties and independent cities, controls for portable fuel containers, mobile equipment repair /refinishing, consumer products, solvent metal cleaning, and the archit ectural and industrial maintenance rules were added. The counties/independent cities (FI PS code) included in the changes for Base G were: Alexandria City (51510), Arlington (51013), Fairfax City (51600), Fairfax (51059), Falls Church City (51610), Fredericksburg City (51630), Loudoun (51107), Manassas City (51683), Manassas Park City (51685), Prince Willia m County (51153), Spotsylvania (51177), and Stafford (51179). Not all OTC rules applied to all counties/cities.

2.2.1.2 Stationary area source growth
As indicated above, growth factors for the Ba se F and Base G 2009 and 2018 inventories were
obtained from the U.S. EPA and ar e linear interpolations of the growth factors used for the Clean Air Interstate Rule (CAIR) projections. The gr owth factors for the CAIR obtained by MACTEC were developed using a base year of 2001 and provided growth factors for 2010 and 2015.
MACTEC used the TREND function in Micr osoft ExcelTM to calcu late 2002, 2009 and 2018 values from the 2001, 2010 and 2015 values. The TREND function provides a linear interpolation of intermediate values from a know n series of data points (in this case the 2001, 2010 and 2015 values) based on the equation for a strai ght line. These values were calculated at the State and SCC level with the excepti on of paved road emissions (SCC = 2294000000). The growth factors for paved roads were available in the CAIR data set at the State, county and SCC level so they were applied at that level.

Prior to utilizing the growth factors from th e CAIR projections, MACTEC confirmed that all SCCs found in the VISTAS 2002 base year inventor y were in the CAIR file (for Base F the starting point was the version 3.1 2002 base year inventory, for Base G the starting point was the Base F 2002 base year inventory). Some SCCs were not found in the CAIR file. For those SCCs,

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 137 

# the growth factors used were derived in one of five ways. First where po ssible, they were taken from a beta version of EGAS 5.0. In other cases, the growth factor wa s set to one (i.e., no growth). In other cases, a similar SCC that had a CAIR growth factor was used. In a few cases a growth factor based on an average CAIR growth at the 6 digit SCC level was calculated. Finally a number of records used populati on as the growth surrogate. For the Base G inventory, CAIR growth factors for fuel fired area sources were replaced with EGAS 5.0 gr owth factors (used in conjunction with AEO fuel efficien cy factors). A comment field in the growth factor file was
used to mark those records that were not taken di rectly from the CAIR pr ojection growth factors.

2.2.1.3 Differences between 2009/2018
Methodologically, there was no difference in the way that 2009 and 2018 emissions were calculated for stationary area sources. The indivi dual control and growth factors were different (due to the linear interpolation used to calculate th e values) but the calculation methods were identical. This applies to both Base F and Base G.

The only exception to this is for the State of North Carolina for Base G. North Carolina provided an emissions update file used to override calcu lated projections for a number of area source categories. The values in thes e files (provided for both 2009 and 2018) were used to overwrite the calculated projected emi ssions in the final NIF file.

2.2.2 Agricultural area sources
The general approach used to calculate project ed emissions for agricu ltural area sources (predominantly NH 3 

# emission sources) was as follows:

1. MACTEC used the version 3.1 2002 base year inventory data (which was based on the CMU ammonia model version 3.6).

2. MACTEC worked with the VISTAS States (via the Agricultural Sources SIWG) to obtain any State specific growth and/or future controls from the States for agricultural

sources.

3. Since the base year emissions were unc ontrolled, and no future controls for these sources were identified, MACTEC projecte d the agricultural em issions using Statespecific growth if available, otherwise the U.S. EPA’s Interstate Air Quality Transport Rule (IAQTR)/Ammonia inventory wa s used to develop the growth factors used to project the revised 2002 base y ear inventory to 2009 or 2018. Since the IAQTR inventory was only used to construc t growth factors rather than using the emissions directly, no updated growth f actors were prepared from the CAIR inventory values.

# 4. MACTEC then provided the final draft inventory for review and comment by the
VISTAS States.

No change in the agricultural area source emi ssion projections were made between Base F and
Base G other than the removal of wild animal a nd human perspiration as a result of their removal from the 2002 base year file for Base G.

2.2.2.1 Control assumptions for agricultural area sources
No controls were identified either by the indi vidual VISTAS States or in the information provided in the EPA’s IAQTR or CAIR Ammoni a inventory documents. Thus all projected emissions for agricultural area sources represent simple growth with no controls.

2.2.2.2 Growth assumptions for agr icultural area sources
Growth for several agricultural area source live stock categories was developed using the actual emission estimates developed by the EPA as part of the NEI. That work included projections for the years 2002, 2010, 2015, 2020, and 2030. The actual emissions themselves were not used other than to develop growth factors since th e 2002 NEI upon which the growth projections were based was prepared prior to th e release of the 2002 Census of Agriculture data which was included in the CMU model (version 3.6) used to develop the Base F 2002 VISTAS base year inventory. Thus VISTAS Agricultural Sources SI WG decided to use the NEI ammonia inventory projected emissions to develop the 2009 and re vised 2018 growth factors used to project
emission for VISTAS. Details on the NEI i nventory and projections can be found at:

http://www.epa.gov/ttn/chief/ap42/c h09/related/nh3inventorydraft_jan2004.pdf . The actual data files for the projected emissions can be found at:

http://www.epa.gov/ttn/chief/ap42/ch09/related/nh3output01_23_04.zip

. In order to use the NEI projected emissions as gr owth factors, several st eps were required. These steps were as follows:

1. NEI projected emissions were only available for the years 2002, 2010, 2015, 2020, and 2030, thus the first task was to calculat e intermediate year emissions for 2009 and 2018. These values were calculated based on linear interpolation of the existing data.

2. Once the intermediate emissions were calculated, MACTEC developed emission ratios to provide growth factors fo r 2009 and 2018. Ratios of emissions were
established relative to the 2002 NEI emissions.

3. Once the growth factors were established, MACTEC then evaluated whether or not all agricultural SCCs within the revised 2002 base year inventory had corresponding

## 139 

# growth factors. MACTEC established that not all SCCs within the base year inventory had growth factors. These S CCs fell into one of two categories:

b. SCCs that had multiple entries in th e NEI but only a single SCC in the 2002 VISTAS base year inventory. The NEI was established using a process model and for some categories of animals, em issions were calculated for several aspects of the process. The CMU mode l version 3.6 which was the basis for the VISTAS 2002 Base F inventory di d not use a process model. As a consequence a mapping of SCCs in th e NEI projections and corresponding SCCs in the CMU inventory was made and for those SCCs an average growth factor was calculated from the NEI pr ojections for use w ith the corresponding SCC in the CMU based 2002 Base F inventory.

c. There were also State, county, SCC trios in the 2002 VISTAS Base F inventory which had no corresponding emi ssions in the NEI files. For these instances, MACTEC first developed Stat e level average growth factors from the NEI projections for use in growing these records. Even after developing State level average growth factors there were still some State/SCC pairs that did not have matching growth. For these records, MACTEC developed VISTAS regional average growth factors at the SCC level from the NEI data.

1. Once all of the growth factors were deve loped, they were used to project the
emissions to 2009 and 2018. Growth factors we re first applied at the State, county and SCC level. Then remaining records we re grown with the State/SCC specific growth factors. Finally, any remaining ungr own records were projected at the SCC level using the VISTAS regional growth factor.

For the livestock categories, the NEI emission project ions only had data for beef and dairy cattle, poultry and swine. Thus for other livestock cate gories and for fertilizers alternative growth factors were required.

The growth factors for other livestock categorie s and fertilizers were obtained from growth factors used for the IAQTR projections made by the U.S. EPA. The methodology for these categories was identical to that used for dairy, beef, poultry and swine with the exception that State/SCC and VISTAS/SCC growth factors were not required for these categories since the IAQTR data contained State, c ounty and SCC level growth fact ors. The IAQTR data provided growth factors for 1996, 2007, 2010, 2015 and 2020. Linear interpolation was used to develop the growth factors for th e intermediate years 2009 and 2018 required for the VISTAS projections.

MACTEC, Inc. 

## 140 

# There were a few exceptions to the methods used for projecting agricultural sources for the VISTAS projections. These exceptions were:

1. All swine emissions for North Carolina were maintained at 2002 levels for each projection year to capture a moratori um on swine production in that State.

2. Ammonia growth factors for a few categories (mainly feedlots) were assigned to be the same as growth factors for PM emissions from the NEI projections. This assignment was made because the CMU model showed emissions from these categories but the NEI projections did not show ammonia emissions but did show PM
emissions.

3. No growth factors were found for horse and pony emissions. These emissions were
held constant at 2002 levels.

There was no change in this method between Ba se F and Base G. Thus Base F and Base G agricultural emissions are the same in each invent ory. Future efforts on the agricultural emissions category should look at any changes made to the CMU model to reflect the model farm approach used by EPA in their inventory plus any updated gr owth factors that may be more recent than the EPA inventory used to develop gr owth estimates for Base F/G.

2.2.2.2.1 Differences between 2009/2018



# Methodologically, there was no difference in the way that 2009 and 2018 emissions were calculated for agricultural area sources. The grow th factors were differe nt (due to the linear interpolation used to calculate the values) but the calculation met hods were identical. In addition
there was no difference between Base F and Base G for this category. Thus Base F and Base G agricultural emissions are the same in each inventory.

Tables 2.2-1 show the differences between Base F and Base G emissions for all area sources (including agricultural sources but excluding fires) for the 2 002 base year and 2009 and 2018 by State and pollutant.

# 2.2.3 Changes to Prescribed Fire for 2009/2018 Base G
Just prior to release of versi on 3.1 of the VISTAS inventory seve ral 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 (memo from Bill Jackson and Cindy Huber, August 13, 2004). However data were not readily available to incorporate those changes up through the Base F inventory. As a consequence MACTEC wo rked with Federal Land Managers to acquire the data necessary to provide 2009 and 2018 specific projections for the prescribed fire component of the Base G fire invent ory. The 2009 and 2018 projections developed using the method described below ar e being used by VISTAS as the 2009 and 2018

# base case inventories for all States except FL. For FL the supplied data from the FLMs is not being used as FL felt that their data adequately reflected current and fu ture prescribed burning practices. The “typical” fire projection is the 2002 base prescribed fire projection.

One of the biggest issues in preparing the proj ection was how best to incorporate the data. Two agencies submitted data: Fish and Wildlife Service (FWS) and Forest Service (FS). FWS submitted annual acreage data by National Wildlife Refuge (NWR) and county with estimates of acres burned per day for each NWR. FS provi ded fire-by-fire acreage estimates based on mapping projected burning acreage to current 2002 modeling days. However, FWS did not submit data for VISTAS original base year pr eparation process, thus there was no known FWS data in the 2002 actual or typi cal inventories. Thus MACTEC had to develop a method that could use the county level data submitted by FWS.

In addition, despite the fact that the FS submitte d fire-by-fire data for the 2002 actual inventory and had mapped the projections to current bu rn days in the 2002 act ual inventory, MACTEC could not do a simple replacement of thos e records with the 2009/2018 projections. This
situation was created because several VISTAS St ates run a prescribed fire permitting program. To avoid double counting, only State data was used in those States for the 2002 actual inventory.
Thus there were no Federal data in those States since the Federal data could have potentially duplicated State-supplied prescribed fire data. In VISTAS States without permit programs, the FS supplied data for 2002 was used and those reco rds were marked in database. Thus for those States, the FS supplied 2009/2018 data could be directly substituted for the 2002 data.

The method used by MACTEC to include the FS da ta applied a county level data approach for FS data where a State had a prescribed fire pe rmitting program and a fire-by-fire replacement for FS data in States without permit programs. MACTEC used a county level approach for all of the FWS data. The approach used for eac h data set is discussed below.

For the FWS data MACTEC summed the annual acres burned supplied by the FWS across all NWRs in a county. We then subtracted out 2002 acreage for that county from the FWS projected acreage annual total to avoid double counting. Th e remaining acreage was then multiplied by 0.8
to account for blackened acres instead of the total perimeter acres that were reported. The revised total additional FWS acreage was then added to th e total county “typical” acreage to determine future acreage burned for either 2009 or 2018. MA CTEC then allocated the increased acreage to current modeling days. The average daily acre s burned data provided by FWS per NWR/county was used to allocate the acreage to the correct nu mber of days required to burn all of the acres. Guidance supplied by FWS indicated that up to thr ee times the average daily acres burned could potentially be allocated to any one day. Thus if the estimated acreage per day were 100 acres then up to 300 acres could actually be allocated to a particular day. This approach (use of up to three times the average daily acres burned) was us ed if there were an insufficient number of 2002

# modeling days available to account for all of the acreage increase. MACTEC used an incremental approach to using the increase above the base average daily acres. First we used twice the average daily acreage if that was suffici ent to completely allocate the increased acreage over the total number of days avai lable. If that wasn’t sufficient then we used three times the average daily acres burned to allocate the acreag e. We applied the highest increases to days in the database that already had the highest acr eage burned since we felt those days were most likely to represent days with representative conditions for conducti ng prescribed burns.

The approach used by MACTEC for the FS was s lightly different. For States that had permit programs, we used similar approach to the FW S county level approach. First we summed the FS data at county level, we then added that value to the typical acreage and then we allocated the acres to current modeling days. The mapping to current modeling days was performed by Bill Jackson of the USFS and provided to MACTEC. For States that do not have a prescribed fire permit program, MACTEC simply re placed the current fire-by-fire records in the database with fire-by-fire records from the FS and recalculated emissions based on fuel model and fuel loading. We also applied the same 0.8 corr ection for blackened acres applied to all FS 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 i nventory, fire acreage increased or decreased from acreag e on the same fire days as we re 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 fu ture 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 incr ease to that same day).

The table below shows how the FWS data for Okefenokee NWR were allocated for 2009 for Clinch County (Okefenokee NWR is located in f our different counties). You can see that the
total additional acres for the Clinch County portion of Okef enokee NWR was 1,956 acres. Two hundred eighty (280) acres were the estimated average daily acres burned for that NWR/county combination. Thus to allocate the entire 1,956 acres would require al most 7 burn days (1,956 divided by 280). However only 5 burn days were found for Clinch County in the 2002 actual fire database. Thus we allocated twice the average acreage to the burn day with the most acres
burned in the 2002 actual fire da tabase (since our me thod allowed us to increase the average daily acres burned up to three times the recomm ended level). Thus the first burn day received 560 acres and all others received 280 except the fina l day which received 276 to make the total equal to the required 1,956 acres. The table also indicates that the increased acres burned

# The figure below shows the increases for prescrib ed burning in the four counties that comprise the Okefenokee NWR area (which also includes FS land). In this figure you can see the additional acreage added for the burn days from FWS and the individual day increases caused by projected increases in prescrib ed burning based on FS data. It should be noted that while the emissions represent 2009, all fire event dates list ed are for 2002 to match up with the base year meteorology used in modeling exercises.

Table 2.2-4 shows the percentage difference be tween the 2009 and 2018 projections developed
for Base F and Base G. Base G includes the revised prescribed burning estimates described above. Values are calculated using Base F as the basis for change, thus negative values imply an
increase in emissions for Base G.

# 2.2.4 Quality Assurance steps
Throughout the inventory developm ent process, quality assuran ce steps were performed to ensure that no double counting of emissions o ccurred, to ensure that a full and complete inventory was developed for VISTAS, and to ma ke sure that projecti on calculations were working correctly. Quality assurance was an impo rtant component to the inventory development process and MACTEC performed the following QA st eps on the stationary and agricultural area source components of the 2009 and re vised 2018 projection inventories:

1. All final files were run through EPA’s Format and Content checking software.

2. SCC level emission summaries were prepared and evaluated to ensure that emissions
were consistent and that th ere were no missing sources.

3. Tier comparisons (by pollutant) were developed between the 2002 base year inventory and the 2009 and 2018 projection i nventories. In addition, total VISTAS pollutant summaries were prepared to co mpare total emissions by pollutant between versions of the inventory (e.g., between Base F and Base G).

4. Data product summaries were provided to both the VISTAS Emission Inventory Technical Advisor and to the SIWG repr esentatives for review and comment. Changes based on these comments were implemented in the files.

5. Version numbering was used for all i nventory files developed. The version numbering process used a decimal system to track major and minor changes. For example, a major change would result in a version going from 1.0 to 2.0. A minor change would cause a version number to go from 1.0 to 1.1. Minor changes resulting from largely editorial changes would result in a change from 1.00 to 1.01.

2.3 Mobile Sources

Our general approach for assembling data was to use as much existing data from the pre-Base F preliminary projections as possibl e for these inventories, supple ment these data with easily available stakeholder input, and provide the results for stakeholder review to ensure credibility. To develop the “base case” projections, MACTEC originally assembled data to develop two 2009 and 2018 base case inventories: 1) an inventory that incl uded all “on-the-books” control programs and 2) an “on-the-way” in ventory that included controls th at were likely to be “on-theway”. For the Base F and Base G emission forecas ts to the mobile source sector, “on-the-books” and “on-the-way” are defined w ith the same strategies and th erefore only a single projection scenario was developed for each forecast year.

To ensure consistency across evaluation years, the 2009 and 2018 base case inventories were developed, to the maximum extent practical, usin g methodologies identical to those employed in

# developing the 2002 on-road portion of the revi sed 2002 VISTAS base year inventory. All modifications to the 2002 inventory methods were developed in consulta tion with the Mobile Source Special Interest Workgroup (MSSIWG). Ge nerally, modifications were only made to properly account for actual change s expected in the interveni ng period (i.e., between 2002 and 2009 and between 2002 and 2018), but the underlyi ng inventory development methodology was identical, except to the extent re quested by VISTAS or the MSSIWG.

MACTEC developed a preliminary 2018 inventory in early 2004. That inventory was designed to 1) be used for modeling sensitivity evaluations and 2) help establish the methods that would be used for the final 2018 inventory and the in itial 2009 inventory. Since that work took place prior to the revision of the 2002 ba se year inventory data files, MACTEC provided a review of the data and methods used to develop on-road mo bile source input files for the initial 2002 base year inventory prior to developing the prel iminary 2018 inventory. Through this review, MACTEC determined the following:

 

# On-road VMT. Most States provided local da ta for 2002 (or a neighboring year that was converted to 2002 using appropr iate VMT growth surrogates such as population). Since these data were not applicable to 2018 due to intervening growth, input for 2018 was
solicited from the MSSIWG. At the same time we researched county-specific growth rate data utilized for recent national rulemakings as a backstop approach to State supplied VMT projections.

 

# Modeling Temperatures. Actual 2002 temperat ures were used for the initial 2002 base year inventory.

 

# Vehicle Registration Mix (age fractions by type of vehicle) . A mix of State, local, and
MOBILE6 default data were used for the 2002 in itial base year inventory. Forecast data were solicited from the States, with a fallback position that we hold th e fractions constant
at their 2002 values.

 

# Vehicle Speed by Roadway Type. For the 2002 initial base year inventory, speeds varying by vehicle and road type were used.

 

# VMT Mixes (fraction of VMT by vehicle t ype). A mix of State, local, and quasi MOBILE6 default (i.e., MOBILE6 defaults normalized to better reflect local conditions) data were used for the 2002 initial base year inventory. Forecast data were solicited from
the States.

 

# Diesel Sales Fractions. As with the VMT mix data, the diesel sales fraction data employed for the 2002 initial base year inventory represents a mix of State, local, and quasi MOBILE6 default data. The issues rela ted to updating these da ta to 2018 are also

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

# similar, but are complicated by the fact that MOBILE6 treats diesel sales fraction on a model year, rather than age specific basis. Therefore, diesel sales fractions generally cannot be held constant across time. Once ag ain, we solicited any lo cal projections, with a fallback position that we would keep the da ta for 2002 and earlier model years constant for the forecast inventory, supplemented w ith MOBILE6 default data for 2003 and newer model years.

 

# State/Local Fuel Standards. For the 2002 init ial base year inventory, these data were based on appropriate local requirements a nd updated data for 2018 was only required if changes were expected between 2002 and 2018. There are some national changes in required fuel quality for both on-road and non -road fuels that are expected to occur
between 2002 and 2018 and these would be reflec ted in the 2018 invent ory in the absence of more stringent local fuel controls. Expect ed changes in local fuel control programs
were solicited.

 

# Vehicle Standards. The 2002 initial base ye ar inventory assumed NLEV applicability. This was altered to reflect Tier 2 for 2018, unl ess a State indicated a specific plan to adopt the California LEV II program. If so, we made the required changes to implement those plans for the preliminary 2018 inventory.

 

# Other Local Controls. This includes vehicle emissions inspection (i.e., I/M) programs, Stage II vapor recovery programs, anti ta mpering programs, etc. By nature, the assumptions used for the 2002 initial base ye ar inventory vary acr oss the VISTAS region, but our presumption is that these data accura tely reflected each State’s situation as it existed in 2002. If a State had no plans to change program requirements between 2002 and 2018, we proposed to maintain the 2002 program descriptions without change. However, if a State planned changes, we re quested information on those plans. In the final implementation of the Base F and ear lier inventories, Stag e II controls were exercised in the area source component of the inventory, since the units used to develop Stage II refueling estimates are differe nt between MOBILE6 and the NONROAD models. However, in the Base G inventories, Stage II refueling was moved to the on-road
and non-road sectors.

Once the preliminary 2018 (pre-Base F) base cas e projection inventor y data were compiled, MACTEC applied the data and methods selected and proceeded to develop the preliminary (prebase F) base case 2018 projection inventories. Th e resulting inventories were provided to the MSSIWG in a user-friendly format for review. After stakeholder review and comment, the final preliminary 2018 base case inventories and input files were provided to VISTAS in formats identified by the VISTAS Technical Advisor (in this case, MOBILE input files and VMT, NONROAD input files and annual inventory fi les for NONROAD in NIF 3.0 format). Annual

# inventory files for MOBILE were not developed as part of this work, only input files and VMT forecasts. MOBILE emissions were calculated by VISTAS air quality modeling contractor using the provided files.

2.3.1 Development of on-road mobile source input files
As indicated above, MACTEC prepared a pre liminary version of the 2018 base case mobile inventory input data files. These files were then updated to provide a fina l set of 2018 base case inventory input data files as well as a set of i nput files for 2009. The info rmation below describes the updates performed on the preliminary 2018 files and the development of the 2009 input
data files for Base F emission estimation.

Our default approach to prepar ing the revised 2018 and initial 2009 projection inventories for onroad mobile sources was to estimate the emissions by using either:

1. the revised 2002 data provided by each St ate coupled with the projection methods employed for the preliminary 2018 inventory, or

2. the same data and methods used to generate the preliminary 2018 inventory.

We also investigated whether or not there wa s more recent VMT forecasting data available (e.g., from the CAIR and if appropria te revised the default VMT grow th rates accordingly. This did not affect any State that pr ovided local VMT forecasting data, but would alter the VMT
estimates used for other areas.

Since no preliminary 2009 inventory was developed there did not exist an option (2) above for 2009. As a consequence, MACTEC crafted the 2009 initial inventory for on-road mobile sources using methods identical to those employed for th e 2018 preliminary inventor ies coupled with any changes/revisions provided by the States during the review of th e revised 2002 base year and the 2018 preliminary inventories. Therefore, as was the case for 2018, we obtained from the States any input data revisions, met hodological revisions, and local cont rol program specifications (to the extent that they differed from 2002/2018).

2.3.1.1 Preparation of revised 2018 input data files
Preparation of the revised 2018 inventor ies required the following updates:

1. The evaluation year was update d to 2018 in all files.

2. The diesel fuel sulfur content was revised from 500 ppm to 11 ppm, consistent with
EPA data for 2018 in all files.

3. Since the input data is model year, rather than age, specifi c for diesel sales fractions (with data for the newest 25 model years re quired), we updated all files that included

# diesel sales fractions. In the revised 2002 base year files, the data included applied to model years 1978-2002. For 2018, the data incl uded would reflect model years 1994- 2018. To forecast the 2002 data, MACTEC took the data for 1994-2002 from the 2002 files and added data for 2003-2018. To estimate the data for these years, we employed the assumption employed by "default" in MOBILE6 -- namely that diesel
sales fractions for 1996 and later are consta nt. Therefore, we se t the diesel sales
fractions for 2003-2018 at the same value as 2002.

4. VMT mix fractions must be updated to refl ect expected change s in sales patterns between 2002 and 2018. If explicit VMT mi x fractions are not provided, these changes are handled internally by MOBILE6 or externally through absolute VMT distributions. However, files that include explicit VMT mix fractions override the default MOBILE6 update and may or may not be consistent with external VMT distributions. MACTEC upda ted the VMT mix in such files as follows:

First, we calculated the VMT fractio ns for LDV, LDT1, LDT2, HDV, and MC
from the external VMT files for 2018 . This calculation was performed in
accordance with section 5.3.2 of the MOBILE6 Users Guide which indicates:

LDV = LDGV + LDDV

LDT1 = LDGT1 + LDDT

LDT2 = LDGT2

HDV = HDGV + HDDV

MC = MC
The resulting five VMT fractions were then split into the 16 fractions required by MOBILE6 using the distributions fo r 2018 provided in Appendix D of the MOBILE6 Users Guide. This approach ensures that explic it input file VMT
fractions are consistent with the absolute VMT di stributions prepared by MACTEC. These changes were made to all files that included VMT mixes.

5. All other input data were re tained at 2002 values, except as otherwise instructed by the States. This includes all control pr ogram descriptions (I/M, Anti-Tampering Program [ATP], Stage II, etc.), all other fu el qualities (RVP, oxy content, etc.), all other vehicle descriptive data (registrations age distributions, etc.), and all scenario descriptive data. The Stat e-specific updates performe d are described below.

Kentucky: MACTEC revised the 2018 input files for the Lo uisville, Kentucky area (Louisville Air Pollution Control District [APCD]) based on comments received relative to several components of

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 153 

# MOBILE input data. Based on these comments, the input files for Jefferson County, Kentucky were updated accordingly as follows:

a) I/M and tampering program definitions were removed since the program was
discontinued at the end of 2003.

b) The "Speed VMT", "Facility VM T" and "Registration Age Di stribution" file pointers were updated to reflect revised 2002 file s provided by the Louisville APCD.

c) The "VMT Mix" data, which was previous ly based on the default approach of "growing" 2002 data, was replaced by 2018-sp ecific data provided by the Louisville
APCD.

North Carolina:
North Carolina provided a wide range of revise d input data, including co mplete MOBILE6 input files for July modeling. MACTEC did not use the provided input files dir ectly as they did not match the 2002 NC input files for critical elem ents such as temperat ure distributions and gasoline RVP (while they were close, they were slightly different). To maintain continuity between 2002 and 2018 modeling, MA CTEC instead elected to revise the 2002 input files to reflect all control program a nd vehicle-related changes imp lied by the new 2018 files, while retaining the basic temperature and gasoline RVP assumptions at their 2002 values. Under this approach, the following changes were made:

a) NC provided a county cross reference file specific to 2018 that differed from that
used for 2002. We removed files that were referenced in the 2002 input data and replaced those files with t hose referenced in the 2018 data . In addition, since NC only provided 2018 input files for July, we estima ted the basic data for these new files for the other months by cross referencing the target files for 2002 by county against the target files for 2018 by county.

b) We then revised the 2002 version of each i nput file to reflect the 2018 "header" data included in the NC-provided 2018 files. Thes e data are exclusivel y limited to I/M and ATP program descriptions, so that the 2002 I/M and ATP da ta were replaced with
2018 I/M and ATP data.

c) We retained the registration age fractions at their 2002 "value s" (external file pointers) as per NC instructions.

d) We retained all scenario-specific data (i.e ., temperatures, RVP, etc.) at 2002 values, which (as indicated above), we re slightly different in most cases from data included in the 2018 files provided by NC. We believe these differences were due to small
deviations between the data assembled to support VISTAS 2002 and the process used to generate the 2018 files provided by NC, and that revising the VISTAS 2002 data to

# reflect these variations was not appropriate given the resu lting inconsistencies that
would be reflected between VISTAS 2002 and VISTAS 2018.

e) NC also provided non-I/M versions of the 2018 input files that would generally be used to model the non-I/M portion of VMT. Wh ile these files were retained they were not used for the 2018 input data preparation.
Finally, NC also provided a speed profile file and a speed prof ile cross reference file for 2018. We did not use these in our updates as they ha ve no bearing on the MOBILE6 input files, but they were maintained in case they needed to be included in SMOKE control files for a future year control strategy scenario.

Virginia:

In accordance with instructions from VA, the i nput files that referenced an external I/M descriptive program file (VAIM02.I M) were revised to reference an alternative external file (VAIM05.IM). This change was to make the I/ M program more relevant to the year 2018.

One additional important difference was made with respect to the revised 2018 and initial 2009 on-road mobile source input data files for all States. MACTEC developed updated SMOKE ready input files rather than MOBILE6 files so th at the input data could be used directly by the VISTAS modeling contractor to estimate on-road mobile source emissions during modeling runs.

2.3.1.2 Preparation of initial 2009 input data files

The methodology used to develop the 2009 on-ro ad input files was based on forecasting the previously developed revised 2002 base year input files and is identical to that previously
described for the revised 2018 me thodology except as follows:

1. The evaluation year was updated to 2009.

2. Diesel fuel sulfur content was revised from 500 ppm to 29 ppm. The 29 ppm value was derived from an EPA report entitled "Summary and Analysis of the Highway Diesel Fuel 2003 Pre-compliance Re ports" (EPA420-R-03-013, October 2003), which includes the Agency's estimates for the year-to-year fuel volumes associated with the transition from 500 ppm to 15 ppm di esel fuel. According to Table 2 of the report, there will be 2,922,284 barrels per da y of 15 ppm diesel distributed in 2009 along with 110,488 barrels per day of 500 ppm diesel. Treating the 15 ppm diesel as 11 ppm on average (consistent with EPA a ssumptions and assumptions employed for the 2018 input files) and sales weighting the two sulfur content fuels results in an average 2009 diesel fuel sulfur content estimate of 29 ppm.

# 3. Diesel sales fractions were updated identic ally to 2018 except that the diesel sales
fractions for 2003-2009 were set at the same value as those for 2002 (rather than 2003-2018).

4. VMT mix fractions were updated to 2009 using an identical method to that described
for 2018.

5. All other input data were re tained at 2002 values, except as otherwise instructed by individual States (see below). This incl udes all control program descriptions (I/M, ATP, Stage II, etc.), all other fuel qualities (RVP, oxy conten t, etc.), all other vehicle descriptive data (registration age distributions, etc.), and a ll scenario descriptive data.
In addition to the updates described above that were applied to all VISTAS-region inputs, the following additional State-specific updates were performed:

KY – Identical changes to those made for 2018 ( but specific to 2009) were made for the 2009 input files.

NC – Identical changes to those made for 2018 ( but specific to 2009) were made for the 2009 input files.

VA – Identical changes to those made for 2018 were made for 2009.

2.3.2 VMT Data
The basic methodology used to generate the 200 9 and 2018 VMT for use in estimating on-road
mobile source emissions was as follows:

1. All estimates start from the final VMT estim ates used for the 2002 revised base year inventory.

2. Initial 2009 and 2018 VMT estimates were based on linear growth rates for each State, county, and vehicle t ype as derived from the VMT data assembled by the U.S. EPA for their most recent HDD (heavy duty diesel) rulemaking. The methodology used to derive the growth factors is iden tical to that employed for the preliminary 2018 VMT estimates (which is desc ribed in the next section).

3. For States that provided no independent for ecast data, the estimates derived in step 2
are also the final estimates. These States are: Alabama, Florid a, Georgia, Kentucky, Mississippi, and West Virginia. For States that provided forecast data, the provided data were used to either replace or augm ent the forecast data based on the HDD rule. These States, and the specific approaches employed, are detailed following the growth method description.
The steps involved in performing the grow th estimates for VMT were as follows:

# 1. Linear growth estimates were used (alt hough MACTEC investigated the potential use of nonlinear factors and pres ented that information to the MSSIWG, the decision was made to use linear growth factors instead of nonlinear).

2. Estimates were developed at the vehicl e class (i.e., LDGV, LDGT1, LDGT2, etc.)
level of detail since the base year 2002 estimates were pr esented at that level of resolution. In effect, the count y and vehicle class specific gr owth factors were applied
to the 2002 VMT estimates for each vehicle and road class.

3. Overall county-specific VMT estimates fo r each year (developed by summing the vehicle and road class specific forecasts) were then compared to overall countyspecific growth. Since overall county growth is a more appropriate controlling factor as it includes the combined impacts of all vehicle classes, the initial year-specific vehicle and road class VMT forecasts were normalized so that they matched the overall county VMT growth. Mathemati cally, this process is as follows:

(Est_rv_f) = (Est_rv_i) * (C_20XX / Sum(Est_rv_i))

where: Est_rv_f = the final road/vehicle class-specific estimates, Est_rv_i = the initial road/vehicle class-specific estimates, and C_20XX = the county-specific growth target for year 20XX. Table 2.3-1 presents a basic summary of the fo recasts for the preliminary 2018 inventory for illustrative purposes:

# The following States provided some types of forecast data for VMT. The information presented below indicates how those data were processed by MACTEC for use in the VISTAS projection
inventories.

Kentucky:
Revised 2009 and 2018 VMT mix data were provid ed by the Louisville APCD. Therefore, the distribution of Jefferson County VMT by vehicle type within th e KY VMT file was revised to reflect the provided mix. This did not affect the total forecasted VMT for either Jefferson County or the State, but does alter th e fraction of that VMT accumulate d by each of the eight vehicle types reflected in the VMT file. The follo wing procedure was employed to make the VMT estimates consistent with the provided 2009/2018 VMT mix:

a) The 16 MOBILE6 VMT mix fractions were aggr egated into the following five vehicle types: LDV, LDT1, LDT2, HDV, and MC.

b) The 8 VMT mileage classes were aggregated into the same five vehicle types (across all roadway types) and converted to fractions by normalizing against the total Jefferson County VMT.

c) The ratio of the "desired" VMT fraction (i.e ., that provided in th e Louisville APCD VMT mix) to the "forecasted" VMT fraction (i.e., that calculated on the basis of the forecasted VMT data) was calculated for each of the five vehicle classes.

d) All forecasted VMT data for Jefferson County were multiplied by the applicable ratio from step c as follows:

new LDGV = old LDGV * LDV ratio
new LDGT1 = old LDGT1 * LDT1 ratio
new LDGT2 = old LDGT2 * LDT2 ratio
new HDGV = old HDGV * HDV ratio
new LDDV = old LDDV * LDV ratio
new LDDT = old LDDT * LDT1 ratio
new HDDV = old HDDV * HDV ratio
new MC = old MC * MC ratio

The total forecasted VMT for Jefferson County was then checked to ensure that it was unchanged.

North Carolina:

North Carolina provided both VMT and VMT mix data by county and roadway type for 2018. Therefore, these data replaced the data deve loped for North Carolina using HDD rule growth

# rates in their entirety. Similar data were s ubmitted for 2009. Table 2.3-2 presents the resulting
VMT estimates which differ from the "default" HDD rule estimates as follows:

Table 2.3-2 VMT and HDD Rule Estimates for North Carolina (million miles per year)

North Carolina
2002 106,795

State Data HDD Data
2009 123,396 124,626
2018 129,552 146,989


# As indicated, there are substantial reductions in the State-provided forecast data relative to that derived from the HDD rule. The growth rates for both 2009 and 2018 are only about half that implied by the HDD data (1.15 versus 1.17 for 2009 and 1.21 versus 1.38 for 2018). The resulting growth rates are the lowest in the VISTAS region.

NC did not provide VMT mix data for 2009. Theref ore, the VMT mix fractions estimated using the "default" HDD rule growth rates were appl ied to the State-provided VMT estimates to generate vehicle-specific VMT. Essentially, the default HDD methodology produces VMT estimates at the county-road type -vehicle type level of detail, and these data can be converted
into VMT fractions at that same level of deta il. Note that these are not HDD VMT fractions, but VMT fractions developed from 2002 NC data us ing HDD vehicle-specific growth rates. In effect, they are 2002 NC VMT fractions "grown" to 2009.

The default VMT mix fraction was applied to th e State-provided VMT data at the county and road type level of detail to ge nerate VMT data at the county-ro ad type-vehicle type level of detail. The one exception was for county 063, road 110, for which no VMT data were included in the HDD rule. For this single county/road comb ination, State-aggregate VMT mix fractions (using the HDD growth methodology) were applied to the county/road VMT data. The difference
between road 110 VMT fractions across all NC c ounties is minimal, so there is no effective difference in utilizing this more aggregate appr oach vis-à-vis the more resolved county/road approach.

South Carolina:
South Carolina provided county and roadway type-specific VMT data for several future years. Data for 2018 was included and was used directly. Data for 2009 was not included, but was linearly interpolated from data provided for 2007 and 2010. The data were disaggregated into vehicle type-specific VMT using the VMT mixe s developed for South Carolina using the HDD rule VMT growth rates. Table 2.3-3 presents th e resulting VMT estimates which differ from the
"default" HDD rule estimates as follows:

# Tennessee:
In general, Tennessee estimates are based on the HDD rule growth rate as described in step two. However, Knox County provided independent VMT estimates for 2018 and these were used in place of the HDD rule-derived estimates. The Knox County estimates were total county VMT data only, so these were disaggregated into roadway and vehicle-type VMT using the distributions developed for Knox County in step two using the HDD rule VMT growth rates. No data for Knox County were provided for 2009, so the estimates derived using the HDD rule growth factors were adjust ed by the ratio of "Knox County provided 2018 VMT" to "Knox County HDD Rule-derived 2018 VMT." Table 2.3-4 presents the resulting VMT estimates which
differ from the "default" HDD rule estimates as follows:

# Virginia:
Virginia provided county and roadway type-spe cific annual VMT growth rates and these data were applied to Virginia -provided VMT da ta for 2002 to estimate VMT in both 2009 and 2018. Virginia provided VMT mix data for 2002, but not 2009 or 2018. Therefore, the estimated VMT data for both 2009 and 2018 were disaggregated into vehicle type-specific VMT using the VMT mixes developed for VA using the HDD rule VM T growth rates. Table 2.3-5 presents the resulting VMT estimates which differ from the "default" HDD rule estimates as follows:

# 2.3.3 Base G Revisions
For the development of the VISTAS 2009 and 2018 Ba se G inventories and input files, VISTAS states reviewed the Base F inputs, and provide d corrections, updates and supplemental data as
noted below.

For all states modeled, th e Base G updates include:

 

# Adding Stage II refueling emissions cal culations to the SMOKE processing.

 

# Revised the HDD compliance. (REBUILD EFFECTS = .1)

 

# Revised Diesel sulfur values in 2009 to 43 ppm and 2018 to 11 ppm

In addition to the global changes, individual VISTAS states made the following updates:

KY – updated VMT and M6 input values for selected counties

NC – revised VMT estimates, speeds and ve hicle distributions and updated registration
distributions for Mobile 6.

TN - revised VMT and vehicle registrati on distributions for selected counties.

WV – revised VMT input data

AL, FL, and GA and VA did not provide update s for 2009/2018 Base G, and the Base F inputs
were used for these States.

2.3.4 Development of non-road emission estimates

The sections that follow descri be the projection process used to develop 2009 and 2018 non-road projection estimates, as revised through the sp ring of 2006, for sources found in the NONROAD
model and those sources estimated outside of th e model (locomotives, ai rplanes and commercial marine vessels).

2.3.4.1 NONROAD model sources
NONROAD model input files were prepared in both the fall of 2004 (Base F) and the spring of 2006 (Base G) based on the corresponding 2002 base ye ar inventory input f iles available at the

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

# time the forecasts were developed, with appropria te updates for the projection years. Generally, this means that the Base F 2002 base year inpu t files (as updated through the fall of 2004) were used as the basis for Base F projection year i nput file development and Base G 2002 base year input files as updated through the spring of 2006 were used as the basis for Base G projection year input file development. Thus , all base year revisions are i nherently incorporated into the associated projection year re visions. Other specific updates for the projection years for
NONROAD model sources consist of:

1. Revise the emission inventory year in th e model (as well as various output file naming commands) to be reflec tive of the projection year.

2. Revise the fuel sulfur content for ga soline and diesel powered equipment.

3. Implement a limited number of local cont rol program charges (national control program changes are handled internally within the NONROAD model, so explicit input file changes are not required).

All equipment population growth an d fleet turnover impacts are al so handled internally within the NONROAD model, so that explicit chan ges input file changes are not required.

Base F Input File Changes:

To correctly account for diesel fuel sulfur cont ent differences between the base and projection years, two sets of input and out put files were prepared for each forecast year, one set for landbased equipment and one set for marine equipm ent. This two-step projection process was required for Base F, because diesel fuel sulf ur contents varied between land-based and marine-based non-road equipment and the Dr aft NONROAD2004 used for Base F allowed only a single diesel fuel sulfur input. Thus, the m odel was executed separately for land-based and marine-based equipment for Base F, and the a ssociated outputs subsequently combined. The specific diesel fuel sulfur cont ents modeled were as follows:
Diesel S (ppm) 2002 2009 2018

Land-Based 2500 348 11

Marine-Based 2500 408 56

As indicated, the Draft NONROAD2004 model was run with both sets of input files and the output file results were then combined to produce a single NONROAD output set.

To correctly account for the national reduction in gasoline sulfur content (a national control not explicitly handled by the NONROAD model) , all NONROAD input files for both 2009 and 2018 were revised to reflect a gasoline fuel sulfur content of 30 ppmW.

# Base G Input File Changes:

With the release of Final NONROAD2005 that was used for the Base G projection year inventory development, the NONROAD model is capab le of handling separate diesel fuel sulfur inputs for land-based and marine-based non-ro ad equipment in a single model execution. Therefore, the two step modeling process desc ribed above for Base F updates was no longer required. Instead, the differential diesel fuel sulfur values are assembled into a single NONROAD input file as follows:
Diesel S (ppm) 2002 2009 2018

Land-Based 2500 348 11

Marine-Based 2638 408 56
Additionally, revised gasoline vapo r pressure data were provided by Georgia regulators for 20
counties 5 

# where reduced volatility requirements were established in 2003. Since this requirement began after the 2002 base year, the vapor pressure values in the base year input files for these
counties are not correct for ei ther the 2009 or 2018 forecast year s. Therefore, to correctly forecast emissions in these counties, the forecast year gasoline vapor pressure inputs were
revised to:
Gasoline RVP (psi) 2002 2009 2018 Spring 9.87 9.2 9.2

Summer 9.0 7.0 7.0

Fall 9.87 9.2 9.2

Winter 12.5 12.5 12.5
The summer vapor pressure was simply set equal to the 2003 control value, while the spring and fall vapor pressures were adjusted to reflect a single month of the reduced volatility limit. The winter volatility was assumed to be unaff ected by the summertime control requirement.

2.3.4.1.1 Differences between 2009/2018



# Other than diesel fuel sulfur content and the ye ar of the projections, th ere are no differences in the methodology used to estimate emissions fr om NONROAD model sources. As indicated above, however the Base F 2009/2018 projections were developed us ing Draft NONROAD2004, while the Base G 2009/2018 projections were made using Final NONROAD2005.

# 2.3.4.2 Non-NONROAD model sources
Using the 2002 base year emissions inventory fo r aircraft, locomotives, and commercial marine vessels (CMV) prepared as de scribed earlier in this doc ument, corresponding emission projections for 2009 and 2018 were de veloped in both the fall of 2004 (Base F) and the spring of 2006 (Base G). This section describes the procedur es employed in developing those inventories. The information presented is intended to build off of that presented in th e section describing the 2002 Base F base year inventory. It should be r ecognized that for both the Base F and Base G inventories, the base year inventory used to develop the emission forecasts was the latest available at the time of forecast development. Generally, this means that the 2002 base year inventory as updated through the fall of 2004 was used as the basis for the Base F projection year inventory development, and the Base F 2002 base y ear inventory was used as the basis for Base G projection year inventory development. Thus, a ll base year revisions (a s described earlier in this document) are inherently incorporated in to the associated proj ection year revisions.

Base F Revisions:

# Although some of the data utilized was updated, the methodology used to develop the Base F 2009 and 2018 emissions forecasts for aircraft, loco motives, and CMV is identical to that used earlier to develop preliminar y 2018 Base 1 (“On the Books”) and 2018 Base 2 (“On the Way”) inventories. Briefly, the met hodology relies on growth and cont rol factors developed from inventories used in support of recent EPA rule makings, and consists of the following steps:

(a) Begin with the 2002 base year emission estimates for aircraft, locomotive, and CMV as described above (at the State-county- SCC-pollutant level of detail).

(b) Detailed inventory data (both before and after controls) for these same emission sources for 1996, 2010, 2015, and 2020 were obtained from the EPA's Clean Air Interstate Rule (CAIR) Technical Support Document (which can be found at http://www.epa.gov/cair/pdfs/finaltech01.pdf). Using these data, combined growth and control factors for the period 2002-2009 a nd 2002-2018 were estimated using straight line interpolation betwee n 1996 and 2010 (for 2009) and 2015 and 2020 (for 2018). This is done at the State-county-S CC-pollutant level of detail.

(c) The EPA growth and control data are matc hed 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 poin t. Unfortunately, actual match results were not always ideal, so additional matching criteri a were required. For s ubsequent reference, this initial (highest resolution) matching cr iterion is denoted as the “CAIR-Primary”
criterion.

(d) A second matching criterion is applied that utilizes a simila r, but higher-level SCC (lower resolution) matching approach. For exam ple, SCC 2275020000 (commercial aircraft) in the 2002 base year inventory data would be matched with SCC 2275000000 (all aircraft)
in the CAIR data. This criteri on 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 remained, so a third leve l matching criterion was required.

(e) In the third matching step, the most frequent ly used SCC in the EPA CAIR files for each of the aircraft, locomotive, and commercial ma rine sectors was averaged at the State level to produce a “default” State and pollutant-sp ecific growth and c ontrol factor for the sector. The resulting factor is used as a “default” grow th factor for all unmatched county-SCC-pollutant level data in each State. In effect, St ate-specific growth data are applied to county level data for which an explicit match between the VISTAS 2002 base year data and EPA CAIR data could not be developed. The default growth and control

## Documentation of the Base G2 and Best & Final 2002 Base Year, 2009 and 2018 Emission Inventories

MACTEC, Inc. 

## 166 

# SCCs are 2275020000 (commercial aircraft) for the aircraft sector, 2280002000 (commercial marine diesel total) for the CMV sector, and 2285002000 (railroad equipment diesel total) for the locomotive s ector. Matches made usi ng this criterion are denoted as “CAIR-Tertiary” matches.

(f) According to EPA documentation, the CAIR baseline emissions include the impacts of the (then proposed) Tier 4 (T4) non-road diesel rulemaking, which implements a low sulfur fuel requirement that affects bo th future CMV and locomotive emissions. However, the impacts of this rule were origin ally intended to be excluded from the initial VISTAS 2018 forecast, which was to include on ly “on-the-books” controls. (The T4 rule was finalized subsequent to the developmen t of the preliminary 2018 inventory in March of 2004.) Given its final status , T4 impacts were moved into the “on the books” inventory for non-road equipment. In addition, since th ere are no other proposed rules affecting the non-road sector between 2002 and 2018, there is no difference between the 2018 “on the books” and 2018 “on the way” inventories for th e sector; so that only a single forecast inventory (for each evaluation year) was de veloped. Nevertheless, since the algorithms developed to produce the VISTAS forecasts we re developed when there was a distinction between the “on the books” and “on the way” inve ntories, the distinct algorithms used to produce the two inventories have been ma intained 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 changed between the proposed and final T4 ru les. Thus, previous EPA inventories that include the proposed T4 impacts would not be accurate. Therefore, the procedural
discussion continues to reflect the distinc tions between non-T4 and T4 emissions, as
these distinctions continue to be intrinsi cally important to the forecasting process. Therefore, a second set of EPA CAIR files th at excluded the Tier 4 diesel impacts was obtained and the same matching exercise de scribed above in step s (b) through (e) was performed using these “No T4” files. It is im portant to note that the matching exercise described in steps (b) through (e) cannot si mply be replaced because the “No T4” files
obtained from the EPA include only those SCCs specifically a ffected by the T4 rule (i.e., diesel CMV and locomotives). So in effect, the matching exercise was augmented (rather than replaced) with an additio nal three criteria analogous to those described in steps (c) through (e), and these are denot ed 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 matche s 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 pr ovided these forecasts, as that State 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 factor s were applied only to commercial (SCC 2275020000) and air taxi (SCC 2275060000) emissions. Emissions for ecasts 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. Table 2.3-7 presents the locally generated growth factor s applied in North Carolina.

37081 0.97 0.89

37119 1.15 1.01

37183 0.88 0.81

Note:
Growth factor = Year Emissions/2002 Emissions. Under CAIR approach, 2009 = 1.16 to 1.17 for all 4 counties. Under CAIR approach, 2018 = 1.36 to 1.37 for all 4 counties.



# (h) Using this approach, each State-county-SCC-pollutant was assigned a combined growth and control factor using the EPA CAIR for ecast or locally provided data. The 22,838 data records for aircraft, locomotives, and CMV in the 2002 revised base year emissions file were assigned growth factors in acco rdance 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 th e 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 st andards 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 SO 2 

# and PM emissions. Expected fuel sulfur

# contents were obtained for each evaluati on year from the EPA technical support document for the final T4 rule ( Final Regulatory Analysis: C ontrol of Emissions from Non-road 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 ppmW in 2009 and 56 ppmW in 2018. These co mpare to expected non-T4 fuel sulfur levels of 2599 ppmW in 2009 and 2336 ppmW in 2018. Table 2.3-8 uses calculated
emissions estimates for base and T4 c ontrol scenarios to estimate emission reduction impacts.

# However, since the diesel fuel sulfur c ontent assumed for the 2002 VISTAS base year inventory, upon which both the 2009 and 2018 inventories were ba sed, is 2500 ppmW, a small adjustment to the emission reduction mu ltipliers calculated from the T4 rule is appropriate since they are measured relative to modestly different sulfur contents (2599 ppmW for 2009 and 2336 ppmW for 2018). Correcting for these modest differences produces the emission reduction impact estim ates relative to forecasts based on the VISTAS 2002 inventory shown in Table 2.3-9.

The only exception is for Palm Beach C ounty, Florida, where CMV emissions are reported as “all fuels” rather than separately by residual and diesel fuel components. To estimate T4 impacts in Palm Beach County, th e ratio of diesel CMV emissions to total

# Utilizing this approach, emission inventory fo recasts for both 2009 and 2018 were developed. As indicated in step (b) above, basic growth factor s were developed using EP A CAIR inventory data for 1996, 2010, 2015, and 2020. From these data, equiva lent EPA CAIR inventories for 2002 and 2009 were developed through linear interpolati on of the 1996 and 2010 inventories, while an equivalent CAIR inventory for 2018 was develope d through linear interp olation of the 2015 and
2020 inventories. Growth factors for 2009 and 2018 we re then estimated as the ratios of the
CAIR 2009 and 2018 inventories to the CAIR 2002 inventory.

During the development of the preliminary 2018 VI STAS inventory in Ma rch 2004, this process yielded reasonable results and exhibited no partic ular systematic concerns. However, when the 2009 Base F inventory was developed, significant concerns related to SO 2 

# and PM were encountered. Essentially, what was revealed by the Base F 2009 forecast was a series of apparent

## 170 

# inconsistencies in the CAIR 2010 and 2015 emissi on inventories (as compared to the 1996 and 2020 CAIR inventories) that were masked during the construction of the “longer-term” 2018 inventory.

The apparent inconsistencies are best illustrated by looking at the actual da ta extracted from the CAIR inventory files. Note th at although a limited example is be ing presented, the same general issue applies throughout the CAIR files. Fo r FIP 01001 (Autauga County, Alabama) and SCC 2285002000 (Diesel Rail), the CAIR inventories indicate SO 2 

# emission estimates as shown in
Table 2.3-12.

# Clearly, there is a major drop in emissions between 1996 and 2010, followed by a major increase
in emissions between 2015 and 2020. Several ob servations regarding these changes are important. First, the CAIR data were reported to exclude the T4 rule, so that the drop in emissions should be related to something other than simply a change in diesel fuel sulfur content. Second, if the T4 rule impacts we re “accidentally” included in th e estimates, there should be a resultant 90 percent drop in di esel sulfur between 2010 and 2015; so such inclusion is unlikely. Third, the rate of growth be tween 2015 and 2020 (43 percent per year compound or 97 percent

per year linear) is well beyond any reasonable expecta tions for rail service; and fuel sulfur content during this period is constant both with a nd without T4. In short, there appeared to be no rational explanation for the data, yet the same ba sic relations are observed for thousands of CAIR inventory records.

For the most part, the issue seems to be centered on SO 2 

# 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 eith er inclusion or exclusion of T4 rule impacts is the underlying cause. Moreover, where they occu r, the observed growth extremes generally
affect both SO 2 

# and PM equally, while one would expect PM effects to be buffered if the T4 rule was the underlying cause, since changes in diesel fu el sulfur content will only affect a fraction of PM (i.e., sulfate), while directly reducing SO 2

# The data presented in Figure 2.3-1 illustrates what this meant to the VISTAS forecasting process. Figure 2.3-1 depicts the same data presente d above for Autauga County, Alabama, but normalized so that the interpolated 2002 CAIR em issions estimate equals unity. The “raw” CAIR data is depicted by the markers labeled A, B, C, and D. Interpolated data for 2002 and 2009, based on 1996 and 2010 CAIR data, is depicted by the markers labeled “i” and “ii.” Interpolated data for 2018, based on 2015 and 2020 CAIR data is depicted by the marker labeled “iii.” The relationship between marker “iii” and marker “i” is exactly the relationship used to construct the preliminary (e.g., pre-Base F) 2018 VISTAS invent ory (i.e., a linear growth rate equal to 0.7 percent per year). Thus, it is eas y to see that although there is a major “dip and rise” between 2002 and 2018, it is essentially masked unless data for intervening years are examined. Since no intervening year was examined for the preliminary 2018 inventor y, the “dip and rise” was not discovered. However, upon the development of the 2009 inventory forecast, the issue became obvious, as the marker labeled “ii” readily illustrates. In effect, the 2009 inventory reflected very low negative “growth rates” for some SCCs and pollutants relative to the 2002 inventory, while the 2018 inventory reflected very high and posi tive growth rates for those same SCCs and pollutants. In effect, the path between 2002 and 2018 that previously looked like the dotted line connecting markers “i” and “iii,” now looks like the solid line c onnecting markers “i”, “ii,” and “iii.” For reference purposes, this path is hereafter referred to as the 1996, 2010, 2015, and 2020 growth basis, since all interpolated data is based on CAIR data for those four years.

# In light of the apparent discrepancies i nherent in the 1996, 2010, 2015, and 2020 growth basis data and the inconsistencies its use would impa rt into the 2009 and 2018 VISTAS inventories, a secondary forecasting method was developed. This second method relies on the apparent consistency between the 1996 and 2020 non-T4 CAIR inventories, interpol ating equivalent 2002, 2009, and 2018 inventories solely from these two invent ories. In effect, the CAIR inventories for 2010 and 2015 are ignored. In Figure 2.3-1, this sec ondary approach is depicted by the data points that lie along the lines connecting markers A and D. Markers A and D represent the 1996 and 2020 CAIR inventories, and the markers labe led 1, 2, and 3 represen t the interpolated 2002, 2009, and 2018 CAIR equivalent inventories. The growth rate between 2009 and 2002 is then equal to the ratio of the 2009 and 2002 CAIR i nventories, while that between 2018 and 2002 is equal to the ratio of the 2018 and 2002 CAIR inve ntories. For the exampl e data, the resulting linear growth estimate is 0.3 per cent per year. For reference pur poses, this path is hereafter referred to as the 1996-2020 growth basis, since a ll interpolated data are based on CAIR data for only those two years.

It is perhaps worth noting that the only elemen ts of Figure 2.3-1 that have any bearing on the VISTAS inventories are the growth rates. The ab solute CAIR data are of importance only in determining those rates, as all VISTAS inventor ies were developed on the basis of the VISTAS 2002 base year inventory, not any of the CAIR i nventories. So referring to Figure 2.3-1, the two growth options are summarized in Table 2.3-13.

Table 2.3-13 Growth Options based on CAIR Data

GROWTH BASIS PERCENT PER YEAR 1996, 2010, 2015, 2020 Growth Basis: -9.1% per year (linear) between 2002 and 2009

1996-2020 Growth Basis: +0.3% per year (linear) between 2002 and 2009 1996, 2010, 2015, 2020 Growth Basis: +22.9% per year (linear) between 2009 and 2018

1996-2020 Growth Basis: +0.3% per year (linear) between 2009 and 2018 1996, 2010, 2015, 2020 Growth Basis: +0.7% per year (linear) between 2002 and 2018

1996-2020 Growth Basis: +0.3% per year (linear) between 2002 and 2018


# Of course, these specific rates are applicable only to the example case (i.e., diesel rail SO 2 

# in Autauga County, Alabama), but there are thousands of additional CAIR records that are virtually identical from a growth viewpoint.

While forecast inventories for aircraft, lo comotives, and CMV were developed for 2009 and 2018 using both growth methods, it was ultimately decided to utilize the 1996-2020 growth basis for Base F since it provided more reasonable growth rates for 2009. Tables 2.3-14 and 2.3-15 present a summary of each Base F inventor y, while Tables 2.3-16 and 2.3-17 present the associated change in emissions for each Base F forecast inventory relative to the Base F 2002 base year VISTAS inventory.

# (relative to 2002) for Virginia and West Virginia is notable relative to the other VISTAS States,
but this has been checked and is attributable to a high diesel cont ribution to total CMV SO 2 

# in
the 2002 inventories for these two States.

Figures 2.3-2 through 2.3-13 graphi cally depict the relationships between the various Base F inventories and preliminary 2002 an d 2018 projections prepared prio r to Base F. There are two figures for each pollutant, the first of which presents a comparison of total VISTAS regional emission estimates for aircraft, locomotives, and CMV, and the second of which presents total VISTAS region emission estimates for locomotives only. This two figure approach is intended to provide a more robust illustration of the differences between the various inventories, as some of
the differences are less distinct when viewed th rough overall aggregate em issions totals. All of the figures include the following emissions estimates:

 

# The 2002 Base F base year VISTAS emissi ons inventory (labeled as “2002”),

 

# The 2002 pre-Base F base year VISTAS emissions inventory (labeled as “2002 Prelim”),

 

# The Base F 2009 VISTAS emissions inventor y developed using gr owth rates derived from 1996 and 2020 EPA CAIR data (labeled as “2009”),

 

# The Base F 2018 VISTAS emissions inventor y developed using gr owth rates derived from 1996 and 2020 EPA CAIR data (labeled as “2018”), and

 

# The pre-Base F 2018 VISTAS emissions i nventory estimates as developed using growth rates derived from 1996, 2010, 2015, and 2020 EPA CAIR data (labeled as “2018 Prelim”).

All 12 figures generally illustrate a reduction in emissions estimates between the 2002 pre-Base F emission estimates published in February 2004 (t he initial 2002 VISTAS inventory) and the 2002 Base F emission estimates. This reduction gene rally results from emission updates reflected
in the State 2002 CERR submittals used to de velop the Base F 2002 base year inventory, although the major differences in ag gregate PM emission estimates are driven to a greater extent by modifications in the methodology used to estima te aircraft PM in the Base F 2002 base year inventory (as documented under the base ye ar inventory section of this report).

# Base G Revisions:

Table 2.3-18 shows the Base G 2002 base year em issions for each State in the VISTAS region for aircraft, locomotives and CMV. Although some of these data are updated relative to those
used as the basis of the Base F emissions fo recasts, the methodology used to develop 2009 and 2018 emissions forecasts for aircraft, locomotives, and CMV for Base G is identical to that used for Base F (as documented above). The only exceptions are as follows:

(a) As indicated in the discussion of the Base F forecasts, the CAIR (growth rate) matching criteria were overridden for any record for which States provided local growth data. For Base F, only North Carolina provided su ch data. However, for Base G, Kentucky regulators provided growth data for aircraft emissions associated with Cincinnati/Northern Kentucky Internati onal Airport (located in Boone County, Kentucky). These data were applied to all po llutants and all aircraft types (i.e., military aircraft (SCC 2275001000), commercial ai rcraft (SCC 2275020000), general aviation aircraft (SCC 2275050000), and air taxi airc raft (SCC 2275060000)). Emissions forecasts for all aircraft operations in counties other than Boone con tinued to utilize the growth factors developed according to the CAIR ma tching criteria. Table 2.3-19 presents the locally generated growth factors applied in Kentucky. It should be recognized that although the locally provided gr owth factors presented in the table are significantly greater than those that would apply under the CAIR matching criteria, this is to be expected as local regulators noted a very significant decline in activity at the Cincinnati/Northern Kentucky International Airport in 2002 (relati ve to activity in preceding years). Moreover, this downward spike seems to have been alleviated since 2002, so that the provided growth factors re present not only “routine” growth expected between 2002 and the two forecast years, but growth required to offset the temporary
decline observed in 2002.

# (b) Because of the additional emissions records added in Alabama, as discussed in the Base G 2002 base year inventory section of this re port, the total number of emissions records
in the Base G 2009 and 2018 forecasts incr eased to 23,042 (as compared to 22,838 for Base F). The 23,042 data records for aircra ft, locomotives, and CMV were assigned growth factors in accordance with the following breakdown:

72 records matched State-provided growth factors, 4,287 records matched using the CAIR-Primary criterion, 240 records matched using the CAIR-Secondary criterion, 7,511 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 6,354 records matched using th e No T4-Tertiary criterion.

Tables 2.3-20 and 2.3-21 present a summary of the resulting Base G 2009 and 2018 inventories, while Tables 2.3-22 and 2.3-23 present the associ ated change in emissions for each forecast inventory relative to the Base G 2002 base year VISTAS. As was th e case with Base F, the larger
reduction in CMV SO 2 

# emissions in 2009 and 2018 (relative to 2002) for Virginia and West Virginia is notable relative to the other VISTAS States, but is attribut able to a high diesel
contribution to total CMV SO 2 

# in the 2002 inventories for these two States.

Figures 2.3-14 through 2.3-25 graphically depict the relationships between the various inventories, as revised through Base G. There are two figures for each pollutant, the first of which presents a comparison of total VISTAS regional emission estimates for aircraft, locomotives, and CMV, and the second of wh ich presents total VISTAS region emission estimates for locomotives only. This two figure a pproach is intended to provide a more robust illustration of the differences between the various inventories, as some of the differences are less distinct when viewed through overall aggregate em issions totals. All of the figures include the following emissions estimates:

# The pre-Base F 2002 base year VISTAS emissions inventory (labeled as “2002 Prelim”),

# The pre-Base F 2018 VISTAS emissions inve ntory estimates developed using growth rates derived from 1996, 2010, 2015, and 2020 EPA CAIR data (labeled as “2018 Prelim”).

All 12 figures generally illustrate a reduction in emissions estimates between the pre-Base F 2002 emission estimates published in February 2004 and the Base G 2002 base year emission estimates. This reduction generally results from emission updates reflected in the Base F State CERR submittals, although the major differences in aggregate PM emission estimates are driven to a greater extent by modifications in the me thodology used to estimate aircraft PM in the Base F revisions to the 2002 Base F base year inventory (as documented under the base year inventory section of this report).

# 2.3.4.3 Emissions from NONROAD Model Sources in Illinois, Indiana, and Ohio
Base G projection inventories for 2009 and 2018 for NONROAD model sources in the states of Illinois, Indiana, and Ohio were produced us ing a methodology identical to that employed to develop a Base G 2002 base year inventory for th e same states (as documented earlier in this report). This method consists of the extraction of a complete set of county-level input data applicable to each of the three st ates (in each of the two projection years) from the latest version of the EPA’s NMIM model. This includes appr opriate consideration of all non-default NMIM input files generated by the Midw est Regional Planning Organizati on as documented earlier in the discussion of the Base G 2002 base year inve ntory. These input data were then assembled into appropriate input files for the Final NONROAD2005 model and emission estimates were produced using the same procedure employed for the VISTAS region.

Changes noted between the base year (2002) and forecast year (2009 and 2018) input data extracted from NMIM include differences in gaso line vapor pressure, gaso line sulfur content,
and diesel sulfur content in most counties. All temperature data (minimum, maximum, and average daily temperatures) was constant across years.

As described in the discussion of the Base G 2002 base year inventory, counties in the three states were grouped for modeling purposes using a temperature aggregation scheme that allowed for county-specific temperature vari ations of no more that 2 oF fr om group average temperatures (for all temperature inputs). The same grouping scheme was applied to projection year modeling, so that Illinois emissions were modeled using 12 county groups, Indiana emissions were modeled using 9 county groups, and Ohio emissions were modeled using 10 county groups. Thus, 31
iterations of NONROAD2002 were re quired per season per projection year, as compared to the 53 iterations per season pe r projection year required for the VISTAS region.

As was also described in th e discussion of the Base G 2002 base year inventory, several non-default equipment population, growth, activit y, seasonal distribution, and county allocation files are assigned by NMIM model inputs for these counties. As was the case for the base year inventory development, these same non-default assignments were retained for both projection inventories.

2.3.4.4 Differences between 2009/2018
Methodologically, there was no difference in the way that 2009 and 2018 emissions were
calculated for non-road mobile sources. The actual value of the growth fact ors were different for each type of mobile source considered, but the calculation methods were identical.

# 2.3.5 Quality Assurance steps
Throughout the inventory developm ent process, quality assuran ce steps were performed to ensure that no double counting of emissions o ccurred, to ensure that a full and complete inventory was developed for VISTAS, and to ma ke sure that projecti on calculations were working correctly. Quality assurance was an impo rtant component to the inventory development process and MACTEC performed the following QA steps on mobile source components of the 2009 and revised 2018 projection inventories:

1. All final files (NONROAD only) were run through EPA’s Format and Content checking software. Input data files for MOBILE and VMT growth estimates were reviewed by the corresponding SIWG and by the VISTAS Emission Inventory
Technical Advisor.

2. SCC level emission summaries were prepared and evaluated to ensure that emissions
were consistent and that there we re no missing sour ces (NONROAD only).

3. Tier comparisons (by pollutant) were developed between the 2002 base year inventory and the 2009 and 2018 projecti on inventories (NONR OAD only). Total VISTAS level summaries by pollutant were developed for these sources to compare
Base F and Base G emission levels.

4. Data product summaries were provided to both the VISTAS Emission Inventory Technical Advisor and to the SIWG repr esentatives for review and comment. Changes based on these comments were implemented in the files.

5. Version numbering was used for all i nventory files developed. The version numbering process used a decimal system to track major and minor changes. For example, a major change would result in a version going from 1.0 to 2.0. A minor change would cause a version number to go from 1.0 to 1.1. Minor changes resulting from largely editorial changes would result in a change from 1.00 to 1.01.

# 4-40 Final Report – November 2001 

# (Prior material unrelated to VISTAS modeling is intentionally omitted)

While emission rates for HC, CO, and NO x 

# are routinely measured from (new) commercial air
carrier engines under the emissions certification component of International Civil Aviation
Organization (ICAO) regulations, measurement of PM emissions is not required. As a result,
almost all aircraft engine PM emission rate data have been collected under special studies.
Currently, such data exists for only about 20 aircraft engines, with a considerable portion of these
data collected by the U.S. Air Force for military aircraft engines. While emission factors for
these engines are included in the AP-42 database upon which the FAEED and EDMS emission
inventory models were developed, they have not been included in either model due to their
limited applicability. To date, it has been standard EPA practice not to estimate PM emissions
for aircraft engines. However, since the emissions models maintain a placekeeper for PM
emission rates and include PM emission estimates for GSE, it can appear to the uninformed user
that aircraft PM emission rates are zero. As a result, aircraft are often incorrectly considered to be
insignificant PM sources even though those engines tested for PM have demonstrated significant
emission rates. This policy of exclusion by omission is not appropriate in developing an accurate
modeling inventory, even in the absence of a large emissions database. While a precise
emissions estimate cannot be made with available data, it is clear that a zero emission rate is far

from accurate.

As an alternative for this study, measured emissions data for aircraft engines that have been
tested for PM were statistically analyzed to determine whether or not a relationship to other
measured emissions parameters could be established. Intuitively, it was hoped that an inverse
relationship with NO x 

# might be demonstrated, as such a relationship is theoretically attractive.
While the level of sophistication of the statistical analysis is constrained by the quantity of data
available, simple direct and indirect linear relationships can be examined. Because data are not
available for each test engine in each of the four LTO cycle modes and because relationships
might be expected to vary by operating mode (due to significant changes in engine and
combustion efficiency), all statistical analysis was performed for each operating mode
individually.

# 4-41 Final Report – November 2001 

# Statistically significant relationships were found for the direct linear analysis for three of the four
LTO cycle modes. Significant in this context means that coefficient t-statistics for one or more
of the other measured pollutants (HC, CO, or NO x 

# ) indicated a direct relationship with measured
PM (at a confidence level exceeding 95 percent). In all cases, correlation coefficients were poor
(as expected), suggesting a high level of variability and poor predictability of PM emissions for
any given engine. Nevertheless, statistics were unbiased and should provide an accurate
mechanism to initially assess PM emissions on a aggregate basis (i.e., over a range of aircraft
engine models such as those associated with an analysis for an entire set of airport operations).
Only at idle was no significant relation found, which is not surprising given relative engine
inefficiency in this mode.

The indirect linear analysis revealed a consistent and significant inverse relationship between PM

and NO x 

# based on calculated t-statistics. Correlation coefficients continue to be poor, but
t-statistics are generally improved over those of the direct linear analysis (all developed inverse
relations, including idle, were significant at the 99 percent confidence level). In selecting the
most appropriate relationship for estimation of PM emission rates for non-tested aircraft engines,
the statistical analysis that produced the best combination of a significant t-statistic, a relatively
low root mean square error, and an intuitive engineering basis was identified. This was the

inverse NO x 

# relationship for the takeoff (i.e., full throttle) mode of operation. Figure 4-1
illustrates the selected statistical relationship.

With this relationship established, PM emission rate data for the other aircraft operating modes
(i.e., the approach, taxi, and climbout modes) was statistically analyzed against observed PM
emission rate data for the takeoff mode. Statistically significant relations were developed for all
three modes. Table 4-23 presents the coefficients developed for these PM-to-PM regressions as

well as the statistics for the PM-to-NO x 

# regression developed for the takeoff mode. These four
relations were used to develop a set of fleetwide PM emission factors based on measured takeoff

NO x 

# emission rates. These emission factors were then input into the EEA aircraft emissions
model and used to generate PM emission estimates for TIA aircraft operations.

CONVERSION OF MRPO BaseM
POINT SOURCE DATA
TO SMOKE INPUT FORMAT

# MEMORANDUM

To: Pat Brewer, VISTAS From: Gregory Stella, Alpine Geophysics, LLC Re: Conversion of MRPO BaseM Point Source Data to SMOKE Input Format Date: 13 February 2008

The Midwest Regional Planning Organization (MRPO) periodically produces a five State emission inventory for Illinois, Indiana, Michigan, Wisconsin, and Ohio. These data are used as the basis for various MRPO modeling and regulatory analyses. These data are prepared with the he lp of each State’s emission inventory divisions and are felt to be the most representative account for emissi ons activities for those States at any one time.

The most recent version prepared and distributed by MRPO is currently called BaseM. Associated with this 2005 base year inventory release is a set of growth and control factors that are used to additionally simulate future year conditions under “On-The-Books” (base cas e or known control programs requirements to be implemented in future years) or incremental control situations to test sensitivity or strategies which would be implemented in whole or in part during the same future years.

The purpose of this document is to detail the technical steps that were made as part of the conversion of the MRPO BaseM point sources files (electric generating unit [EGU] and non-EGU) into IDA format for ASIP PM-2.5 CAMx modeling of the future year 2009. B ecause of the timing and complications relative to converting multiple and various emission files for all source types, it was determined that only point source emissions would be converted for processing at this time.

Data Sources and Description

A series of data files and associated documentation was obtained from MRPO staff in 2007. These files were the input data sets for base year 2005 and growth and control factors related to MRPO’s BaseM and Round 5 inventories 6 

## . Because of the emission processing tools that MRPO currently executes for its analyses, these files are in formats that are not read by the SMOKE emissions processor currently in use by VISTAS/ASIP modelers (contract teams and participating states). Alpine Geophysics, under the Emissions Inventory Technical Advisor contract, was asked to obtain and convert these data into the formats that could be used by these modeling agencies.

Through additional contact with MRPO staff, the base year 2005 non-EGU point source fi les and associated growth and control factors necessary to forecast the data to 2009 base case conditions were identified and extracted from the originally provided data. EGU sources were identified to be already prepared for the future year (2010 substituted for 2009) and were based on recent IPM 3.0 model runs with incremental adjustment made by MRPO states to best reflect expected emission controls and operating conditions . The “will do” simulation series for EGUs was identified as “egu5b_2010.”

The main purpose of the SMOKE conversion task was to prepare five state emission inventories provided in National Input Format (NIF) format into the IDA format required by the SMOKE model for the criteria pollutants VOC, NOx, CO, SO2, PM-10, PM-2.5, and NH3. Annual emissions were taken directly from the NIF structured inventories with no alternate temporal calculations perfo rmed (e.g., estimate seasonal emissions from annual or annual from seasonal). The temporal allocation module of the SMOKE emissions processor was intended to be used to further define temporal distribution of these emissions.

## No quality assurance (QA) related to the reported valu es in the MRPO was conducted (e.g., it was assumed that reported emission levels were correct) and therefore the QA focus of these tasks was to maintain the integrity of the mass files in the conversion to IDA.

Each set of NIF structured data had a unique set of relatio nal tables necessary to maintain the information required in each source sector based on its repo rting requirements. Alpine had previo usly developed scripts to read the information from each of these relational data sets and co nvert them to the IDA struct ures required by this task. Prior to and after each major source sector was converte d from NIF to IDA, we developed a list of emission summary reports to check that the emissions input into the conversion process were the same as output into the IDA formatted files.

Non-EGU Point Source Conversion

Non-EGU point source emissions from 2005 BaseM were converted to future year 2009 IDA format using the annual emission records directly from th e NIF structured data sets and asso ciated SCC growth factors and unit, facility, county, state, or nationally applied controls 7 

## . These controls were applied in a hierarchical fashion starting with the most defined (unit-segment-pollutant level) th rough least defined (national-SCC-pollutant) and when a match was found during the implementation, no additional cont rols were sought or applied to that emission record. In other words, if a match were found at the unit-segment leve l of control, no additional controls were applied to that segment/pollutant combination again in the forecast process. This prevented multiple control programs from being implemented when the intent of the originally provided cont rol files were to assign a single applicable reduction.

The Round 5 factors for point sources provided by MRPO were in the RPO Data Exchange Format (RPODx) and had growth and control factors available at the State, county , plant, unit, segment, stack, and SCC level of detail. In order to apply these factors in a fashio n consistent with that of the MRPO utilized processing system and duplicative of how MRPO would have generated its BaseM forecasts, a hierarchical approach was ut ilized to match and assign growth and control values.

Growth Factor Application

Using the 2005 EM table from the BaseM inventory files in NIF format, we first selected each emissions record for forecasting. In this conversion case, th ese EM records were limited to those em issions identified as annual using the NIF coding convention. As noted in the limitations sectio n below, there oftentimes were emissions provided by MRPO in a summer season convention.

We next selected the base year for application as the RPODx for growth rates allows for the flexibility of input growth factors for multiple base year inventories. In this assignment, the base year was always 2005, as that was the base year provided by MRPO and the future year was 2009, as selected by ASIP.

The next step was to determine the growth basis for each individual emission record of the file. This “growth basis” is the key with which the growth factor is associated. For point sources, this key is based on a combination of FIPS, SCC, and pollutant codes. Multiple keys are calculated fo r each individual emission reco rd and that key with the highest resolution of matching to the growth factor file using the hierarchy identified in Table 1 below is the one chosen to assign a growth rate to the base year emissions.

## Table 1. Point Source Growth Fact or Application Hierarchy.

Order Key or “Growth/Control Basis” 1 state/county code, 10-digit SCC, pollutant 2 state/county code, 10-digit SCC 3 state code, 10-digit SCC, pollutant 4 state code, 10-digit SCC 5 state/county code, pollutant 6 state/county code 7 state code, pollutant 8 state code 9 10-digit SCC, pollutant 10 10-digit SCC 11 Pollutant

Using the hierarchical application, growth basis, and date s (base year and alternate year ), we matched each emission record to the growth table to obtain a growth factor. The factors are defined in the growth table as a multiplier for the base year period that calculates the alternate year of interest. In other words, multiplying the base year emissions value by the growth factor provides you with the emissions for the alternate year of interest.

When no match from any of the hierarchical keys was identified, a growth rate of 1.00 (no growth) was assigned. This maintained the 2005 emission level in the future year inventory.

Control Factor Application

Similar to the process identified above for the assignment and application of growth f actors, the control factor assignment was based on a hierarchical key, this time, however, using FIPS, plantid, pointid, stackid, segment, SCC, and pollutant codes applied in a parallel pr ocess to the growth factor assignment.

Using the 2005 EM table from the BaseM inventory files in NIF format, we selected each annual emissions record for forecasting. We next select ed the base year for application, and again, the base year was always 2005, as that was the base year provided by MRPO.

Once the base year was identified, we determined the alternate y ear for our forecast. Depend ing on the specific year used in each conversion, gr owth rates were limited to those with a base year of 2005 and a future year less than or equal to that of our forecast. This variation in method is in tended to allow us to identify all controls implemented prior to or during the year of interest and will consider them as viable options at the latest provided level of control.

In other words, since we selected 2009 as the future year of choice, we limit the control factor table to control strategies implemented during or prior to 2009. If in our matching to the control factor table we find that for a certain control basis key there is no match because a program may have been fully implemented in a prior year (say 2007), then we do not want to exclude this reduction fr om our forecast. Additionally, if we find that there are multiple entries in the control factor table because of incr emental implementation of a rule , we select the closest year to that of our intended forecast. So if a particular rule was incrementally implemented from 2005 through 2009 and there were control records available for each year in between, we would select the record with the latest year to apply in our forecast.

The next step was to determine the control basis for each individual emission record of the file. This “control basis” is the key with which the control strategy or technology is associated. Although we developed code to support the hierarchical application of control f actors for the BaseM emissions, all contro l factors provided by MRPO in the Round 5 files were segment-SCC-pollutant specific. This el iminated the need for a sear ch on the key that has the greatest resolution as all matches were at the segment-SCC-pollutant level.

## Using the control basis and dates (base year and alternate year), we matched each emissi on record to the control table to obtain a control factor. The fact ors are defined in the control table as a group of values (control efficiency, rule effectiveness, and rule penetration) for the future year period that gets assigned to an uncontrolled future year emission value. In other words, we first “backed out” existing base year controls from our future year emissions estimate and then multiplied this uncontrolled value by the control factors for the alternate year of interest. These calculations are defined in Equations 1 and 2 below.

Equation 1. Uncontrolled emissions calculation.

Emiss Unc 

## = Emiss Base 

## / (1-((CE Base 

## /100)*(RE Base 

## /100)*(RP Base 

## /100)))

Where,

Emiss Unc 

## = Uncontrolled emissions

Emiss Base 

## = Base year emissions

CE Base 

## = Base year control efficiency

RE Base 

## = Base year rule effectiveness

RP Base 

## = Base year rule penetration

Equation 2. Application of new control calculation.

Emiss New 

## = Emiss Unc 

## *(1-((CE New 

## /100)*(RE New 

## /100)*(RP New 

## /100)))

Where,

Emiss New 

## = Future year emissions

Emiss Unc 

## = Uncontrolled emissions

CE New 

## = Future year control efficiency

RE New 

## = Future year rule effectiveness

RP New 

## = Future year rule penetration
When no match from any of the hierarchical keys was iden tified, the same control effi ciency, rule efficiency, and rule penetration values from the base year inventory were used in the calculation and the only change in emissions would have been the result of growth factor application. In instances where PM-10 annual emissions were found to be less than PM-2.5 annual emission values, the PM-2.5 emission values were changed to equal that of PM-10.

EGU Point Source Conversion

EGU point source emissions from the egu5b_2010 scenario (2010 IPM 3.0 run with modifications) were converted to year 2009 IDA format using the annual emission records directly from the NIF struct ured data sets. Since these emissions already accounted for growth and control appli cation, no additional modifi cations were required.

One ASIP requested modification for its PM-2.5 CAMx m odeling was to adjust the 2009 file to match W. H. Sammis facility’s planned response to the control requireme nts from the consent decree USA vs. Ohio Edison; Civil Action No: 2:99-CV-1181; March 18, 2005. These changes were not implemented in the ASIP 2009 CMAQ runs. These adjustments for SO2 are noted in Table 2 below.

## Conversion Limitations

As noted above, Alpine limited our conversion to all record s in the MRPO point source f iles that were identified as
annual. In some cases the MRPO NIF files had additiona l non-annual summer season emission records configured as a higher percentage than the annual average that was used in our emissions comparison.

In other words, the MRPO file sometimes had two emission record types that it uses for its modeling; one for the summer period and one for the rest of the year. Since SMOKE uses temporal allocation factors to make this summer/winter split, our converted values do not match MR PO's summertime reports. We see a high percentage difference in the Alpine converted data compared to the MR PO output reports in these two States for the July 12 example for this reason.

Since we confirmed this difference and reason for this difference in the 2005 data sets with MRPO, our objective for QA on the projections also included delta emissions from the projection year to the base year. Although the absolute daily emission values (in tpd) were found to be different as noted above, in all cases, the difference between 2005 and the projection year calculations as made by Alpine was within confidence ranges of the ratio of future year to base year as posted by MRPO. See Table 3 below. For this reason, we were convi nced that our projection methodology is capturing the growth and control factors that MRPO applied in its emissions modeling.Atmospheric Sciences GroupAppendix G248Table 3.Emissions Comparison of ASIP Converted and MRPO Non-EGU Emissions.Comparison of ASIP Converted and MRPO Non-EGU EmissionsFIPSST StateVOC NOX CO SO2 PM-10 PM-2.5 NH317 Illinois 61,760 85,142 71,725 150,506 20,315 6,256 1,05918 Indiana 48,287 65,132 339,642 82,040 22,118 12,774 78226 Michigan 36,753 85,014 67,564 55,435 13,235 6,567 78839 Ohio31,530 67,275 212,626 116,942 15,930 10,443 3,23955 Wisconsin 31,377 36,827 43,014 60,955 456 43 346MRPO 209,707 339,390 734,570 465,878 72,054 36,082 6,214FIPSST StateVOC NOX CO SO2 PM-10 PM-2.5 NH3 FIPSST StateVOC NOX CO SO2 PM-10 PM-2.5 NH317 Illinois222.3 315.1 250.9 412.3 55.6 17.1 2.9 17 Illinois218.1 217.8 255.7 335.0 56.0 16.8 2.818 Indiana 132.3 178.4 930.5 224.8 60.6 35.0 2.1 18 Indiana 137.2 175.2 888.8 216.2 60.7 36.5 2.326 Michigan 115.8 232.4 193.6 144.9 40.8 19.3 2.4 26 Michigan 119.1 242.0 206.5 148.6 43.6 20.3 2.439 Ohio86.4 184.3 582.5 320.4 43.6 28.6 8.9 39 Ohio87.1 166.3 540.7 288.0 43.0 27.6 8.355 Wisconsin 86.0 100.9 117.8 167.0 1.3 0.1 0.9 55 Wisconsin 87.7 92.9 120.0 152.1 23.2 0.1 1.0MRPO 642.7 1,011.1 2,075.4 1,269.4 202.0 100.2 17.2MRPO 649.2 894.2 2,011.7 1,139.9 226.5 101.3 16.8FIPSST StateVOC NOX CO SO2 PM-10 PM-2.5 NH3 FIPSST StateVOC NOX CO SO2 PM-10 PM-2.5 NH317 Illinois 29.5% 25.1% 9.8% 32.3% 28.2% 17.3% 17.0% 17 Illinois 33.6% 24.4% 12.7% 29.4% 24.7% 16.6% 16.7%18 Indiana 23.0% 19.2% 46.2% 17.6% 30.7% 35.4% 12.6% 18 Indiana 21.1% 19.6% 44.2% 19.0% 26.8% 36.0% 13.7%26 Michigan 17.5% 25.0% 9.2% 11.9% 18.4% 18.2% 12.7% 26 Michigan 18.3% 27.1% 10.3% 13.0% 19.2% 20.0% 14.3%39 Ohio15.0% 19.8% 28.9% 25.1% 22.1% 28.9% 52.1% 39 Ohio13.4% 18.6% 26.9% 25.3% 19.0% 27.2% 49.4%55 Wisconsin 15.0% 10.9% 5.9% 13.1% 0.6% 0.1% 5.6% 55 Wisconsin 13.5% 10.4% 6.0% 13.3% 10.2% 0.1% 6.0%MRPO 100% 100% 100% 100% 100% 100% 100%MRPO 100.0% 100.0% 100.0% 100.0% 100.0% 100.0% 100.0%ASIP 2009 July 12 Summer Daily Emissions (% of MRPO Total)2009 July 12 Summer Daily Emissions (% of MRPO Total)ASIP 2009 Annual Emissions (Tons/Year)ASIP 2009 July 12 Summer Daily Emissions (Tons/Day)2009 July 12 Summer Daily Emissions (Tons/Day)
