1   Introduction to the Modeling Platform
This Technical Support Document (TSD) describes the development of the emissions inventories used as
inputs to the air quality modeling that the U.S. Environmental Protection Agency (EPA) performed to assess
the impact of the Mercury and Air Toxics Standards (MATS). This document provides the details of
emissions modeling done to support the development of the Regulatory Impact Assessment (RIA) for the
MATS.  The emissions processing described herein and the corresponding air quality modeling were used to
develop benefit-per-ton scaling factors for the benefits calculation as described in the RIA. More
information on this approach can be found in Appendix 5C of the RIA and in the Air Quality Modeling
Technical Support Document (TSD). The emissions inventories were using the Sparse Matrix Operator
Kernel Emissions (SMOKE) modeling system (http://www.smoke-model.org/index.cfm) version 2.7
processed into the form required by the Community Multi-scale Air Quality (CMAQ) model.  CMAQ
simulates the numerous physical and chemical processes involved in the formation, transport, and destruction
of ozone, particulate matter and air toxics.

As part of the analysis for this rulemaking, the modeling system was used to calculate daily and annual PM2.5
concentrations, 8-hr maximum ozone and visibility impairment. Model predictions of PM2.5 and ozone are
used in a relative sense to  estimate scenario-specific, future-year design values of PM2.5 and ozone. These are
combined with monitoring data to estimate population-level exposures to changes in ambient concentrations
for use in estimating health and welfare effects. In this document, we provide an overview of (1) the
emissions components of the modeling platform, (2) the development of the 2005 base year emissions, (3)
the development of the future year baseline emissions, and (4) the development of the future year control
case emissions.

A modeling platform is the collection of the inputs to an air quality model, including the settings and data
used for the model, including emissions data, meteorology, initial conditions, and boundary conditions.  The
2005-based air quality modeling platform used for the proposed utility NESHAP RIA includes 2005 base
year emissions and 2005 meteorology for modeling ozone and PM2.5 with CMAQ. In support of this rule,
EPA modeled the air quality in the Eastern and the Western United States using two separate model runs,
each with a horizontal grid resolution of 12 km x 12 km. These 12 km modeling domains were "nested"
within a modeling domain covering the remainder of the lower 48 states and surrounding areas using a grid
resolution of 36 x 36 km.  The results from the 36-km modeling were used to provide incoming "boundary"
for the 12km grids. Additional details on the non-emissions portion of the 2005v4.3  modeling platform used
for the RIA are described in the air quality modeling TSD.

The 2005-based air quality modeling platform used in support of the RIA is version 4.3 and is referred to as
the 2005v4.3 platform. It  is an update to the 2005-based platform, version 4.1 (i.e., 2005v4.1) used for the
proposal modeling and for the appropriate and necessary finding. The Technical Support Document
"Preparation of Emissions Inventories for the Version 4.1, 2005-based Platform" (see
http://www.epa.gov/ttn/chief/emch/index.html#toxics) provides information on the platform used for the
proposed version of this rule and for the appropriate and necessary finding.  The 2005v4.3 platform builds
upon the 2005-based platform, version 4.2, which was the version of the platform used for the final Cross-
State Air Pollution Rule and incorporated changes made in response to public comments on the proposed
version of that rule.

Table 1-1 provides a high-level summary of the three emissions cases that were modeled in support of the
final rule RIA. The form of the fuel used for mobile sources is a key discriminator between the cases.
Therefore, the mobile source emissions are described with respect to the impacts of the Energy Independence

-------
and Security Act of 2007 (EISA) and the Energy Policy Act of 2005 (EPAct) on mobile source fuels.

In the remainder of this document, we provide a description of the approaches taken for the emissions in
support of air quality modeling for the MATS. In Section 2, we describe the 2005v4.3 platform custom
configurations, ancillary data and 2005 inventory differences from the v4.2 platform. In Section 3, we
describe the speciation differences among each of the cases run. In Section 4, we describe the 2017
Reference (i.e., future year baseline) case as compared to the 2005 base case.  Appendix A provides a
comparison of the ancillary datasets and parameters used for the various MATS emissions cases, and
Appendix B compares the emissions inventory and other input data files used for each of the MATS cases.

2  2005 Emission  Inventories and Their Preparation
As mentioned previously, the 2005  emissions modeling approach for MATS used much of the same data and
approaches as the 2005v4.2 platform. In this section, we identify the differences between the data used for
the MATS 2005v4.3 platform and that used for the 2005v4.2 platform. Section 2.1 provides ancillary data
differences that impact multiple sectors. Section 2.2 discusses the new approach used for emissions
preprocessing and processing for all onroad mobile sources. Section 2.3  discusses the updated nonroad
mobile components.  Sections 2.2 and 2.65  provide differences for the nonpoint and nonpoint (area)
inventories, respectively.

The data used in the 2005 emissions case is often the same as those described in the Final Cross-State Air
Pollution Rule TSD (http://www.epa.gov/ttn/chief/emch/index.html#2005X also known as the CAP-BAFM
2005-based Version 4.2 Platform (i.e., 2005v4.2).  However, some different emissions data are used for this
rulemaking.  All of the documentation provided here describes what was done differently and specifically for
the MATS in contrast to what was done for the 2005v4.2 platform.
In MATS, we used a 2005 base case approach for the year 2005 emissions scenario. This approach is very
similar to that CSAPR Final Rule (formerly known as the "Transport Rule").  A base case approach uses

-------
average year fires and EGU temporal profiles from three years of EGU data.  We use a base case approach
because we want to reduce year-specific variability in some components of the inventory. For example,
large fires vary in location and day of the year each year, and EGU shutdowns and high use on high energy
demand days also vary by year. By using a base case approach, these two aspects of the inventory are
maintained into the future year modeling and therefore do not introduce potentially spurious year-specific
artifacts into the air quality modeling estimates. For MATS, the same biogenic emissions data as the
2005v4.2 platform was used for the 2005 case,  and also for both future-year cases. The only significant data
changes between the 2005 and the 2017 future-year MATS case are the emission inventories and speciation
approaches.

Table 2-1 below lists the platform sectors used for the MATS modeling platform. It also indicates which
platform sectors include HAP emissions and the associated sectors from the National Emission Inventory

2.1  Custom configuration for emissions modeling for MA TS
Unlike the 2005v4.2 platform, the configuration for MATS modeling included additional hazardous air
pollutants (HAPs) and used slightly revised ancillary speciation data.  Both of these differences are described
in this section.

Table 2-2 lists the additional HAP pollutants processed for the MATS 2005v4.3 platform, which were not
included in the 2005v4.2 platform. A "lite" version of the multi-pollutant  CMAQ (Version 4.7) was used
that required emissions only for the species listed in the footnote of Table  2-2. In addition to the model
species differences, the MATS platform had a few additional custom aspects in the 2005 cases. Table 2-3
lists the datasets used by the 2005v4.3 platform that are different from the  2005v4.2 platform.

Another consideration is the speciation across the MATS future-year cases as compared to 2005.  Section 3
provides a detailed account of these differences.  The future-year ancillary data were largely the same as
those in 2005, with no substantial differences for most modeling sectors.  The exception to this is onroad
mobile, which in MATS processing, required several new ancillary input files to support the SMOKE to
MOVES modules; these are discussed in detail in Section 2.4.  All other ancillary data files not required for
SMOKE to MOVES processing can otherwise be found at the 2005-based platform website
(http ://www. epa. gov/ttn/chief/emch/index.html#2005 ).

The MATS 2005v4.3 data files are configured to support the multi-pollutant
(MP) version of CMAQ, whereas the 2005v4.2 platform data file is configured
to support only the non-MP version. Therefore, the MATS data files include
profiles for additional VOC HAP species.

The MATS data file was updated to support SMOKE to MOVES pollutants and
modes, the MP "lite" version of CMAQ, and, to accept inventory Ethanol
(ETOH). The 2005v4.2 platform data file is configured to support only the
non-MP version.
2.2  Onroad mobile sources (onroad)
For each scenario, emissions from cars, trucks and motorcycles were estimated by using the EPA's Motor
Vehicle Emission Simulator (MOVES) to create emission factors that were then input to the Sparse Matrix
Operator Kernel Emissions system (SMOKE). The SMOKE-MOVES Integration Tools combined the county
and temperature-specific emission factors with the activity data to compute the actual emissions. In brief,
our approach was to use the met4moves program to identify a set of temperatures that needed emission rates.
For each scenario, we then ran MOVES repeatedly to produce emission rates by temperature, Source
Classification Code (SCC), speed bin, and representing county.  The moves2smk tool then reformatted the
MOVES rates and selected the appropriate rates for each county and month. Movesmrg then multiplies the
emission rates by county VMT or vehicle population, applies Speciation profiles to develop inventories for
pollutants not included in MOVES and temporally and spatially allocates emissions to individual grid cells
for CMAQ input.

2.2.1  MOVES
For MATS, EPA used a version of the MOVES  2010a model that was enhanced for the proposed Tier 3 rule.
This model included updated information on how fuel parameters impact vehicle emissions and updates on
our understanding of evaporative emissions. It also included some minor updates to emission rates and some
changes designed to make the model run more efficiently. All updates are described in detail in a
memorandum to the docket (U.S. EPA 2012, Memorandum to Docket: Updates to MOVES for the Tier 3
NPRM). The following sections describe inputs to the MOVES model that were specific to this analysis.

The gridded  meteorological input data for the entire year of 2005 were derived from simulations of the
Pennsylvania State University / National Center for Atmospheric Research Mesoscale Model (MM5), a
limited-area, nonhydrostatic, terrain-following system that solves for the full set of physical and
thermodynamic equations which govern atmospheric motions.  The Meteorology-Chemistry Interface
Processor (MCIP) version 3.4 was used as the software for maintaining dynamic consistency between the
meteorological model and chemistry mechanisms.  The hourly gridded meteorological data was post-
processed by met4moves to create maximum temperature ranges, average relative humidity, and a series of
diurnal temperature profiles. MOVES was  run for each temperature bin and diurnal profile. See Sections
2.2.4.1 and 2.2.4.3 for details.

Vehicle population data is a required input for MOVES when modeling on a county basis. Using the
technical guidance provided to states by EPA, the contractor generated appropriate estimates for vehicle
populations for use in the MOVES databases using the county specific VMT and national average ratios of

-------
vehicle populations versus vehicle VMT from the MOVES application.  This method is described in Section
3.3 of the document, "Technical Guidance on the Use of MOVES2010 for Emission Inventory Preparation in
State Implementation Plans and Transportation Conformity" (EPA-420-B-10-023, April 2010), which is
available on the EPA web site at: http://www.epa.gov/otaq/models/moves/index.htm

The county inputs used for the rule were derived from the inputs used for the 2005 National Emissions
Inventory (NEI). This inventory covers the 50 United States (U.S.), Washington DC, Puerto Rico and U.S.
Virgin Islands.  The NEI was created by the EPA's Emission Inventory and Analysis Group (EIAG) in
Research Triangle Park, North Carolina, in cooperation with the Office of Transportation and Air Quality
(OTAQ) in Ann Arbor, Michigan.

OTAQ has developed a consolidated modeling system known as the National Mobile Inventory Model
(NMIM) for calculation of emissions from onroad highway mobile source and nonroad mobile sources.
NMIM documentation is available at http://www.epa.gov/otaq/models/nmim/420r05024.pdf  NMIM
includes a county-level database with the important input parameters specific to each county.  The data in the
NMIM county database (NCD) are used to develop MOBILE6.2 and NONROAD model input files within
NMIM. The basis for the 2005 default vehicle miles traveled (VMT) is data supplied by the Federal
Highway Administration (FHWA), as well as publicly available data from FHWA's Highway Statistics
series.  Details of how the NCD was developed are documented for the NEI "Documentation for the 2005
Mobile National Emissions Inventory, Version 2 (December 2008)",  which can be obtained on EPA web
site: http://www.epa.gov/ttn/chief/net/2005inventory.html

For the onroad portion of the inventory estimates for the rule, including all base and control scenarios, the
current EPA highway mobile source emission model (MOVES) was used. This required conversion of the
NCD database parameters to a format consistent with MOVES.  A contractor was given the assignment
(TranSystems, Contract No. EP-D-06-001, WA 4-65) to convert the NCD database to MOVES formatted
input databases.  This was accomplished with the  assistance of converters designed for this purpose. These
converters are available on the EPA web site at: http://www.epa.gov/otaq/models/moves/tools.htm

All of the county specific onroad data available in the NCD was converted to MOVES format for use at the
county scale consistent with the databases created using the MOVES County Data Manager (CDM), except
for the information regarding fuel properties.  The fuel properties were updated using more recent
information and methods specifically for this rule  and described elsewhere in this document. Any table
entries in the NCD that contained national average default information from the MOBILE6 model were
replaced with the more recent national average default information used by MOVES.

2.2.2  Representing counties
Although EPA compiles county specific databases for all counties in the nation, many of the states can
provide little or no county specific information for most counties. Rather than explicitly model every county
in the nation (there are over 3,000 counties), we have performed detailed modeling for some counties and
less detailed estimates for the other counties.  This has been accomplished in this  rule using a concept called
"representing  counties".

In this approach, we group counties that have similar properties and therefore would have similar emission
rates.  Then, we explicitly model only one county  in the group (the "representing" county) to determine the
rates.  These representative rates are then used, in  combination with county specific activity and meteorology
data to generate emissions estimates for all of the  counties in the group.  This approach dramatically reduces
the number of modeling runs required to generate inventories and still takes into account differences between
counties.

                                                7

-------
As described in Section 2.2.4, in order to generate onroad mobile emissions, MOVES was run in conjunction
with the EPA SMOKE model to generate "grid" level inventories for use in air quality modeling. SMOKE
uses emission rates (not inventories) to generate inventory estimates within each grid. Since SMOKE
handles the differences in the fleet mix, temperatures, speeds and VMT versus location and time, MOVES
can be run in the "emission rate" mode.  As a result, when counties are grouped, they can be grouped
independently of fleet mix, speeds and temperature.  This greatly increases the number of counties that can
be in each grouping, since temperature is a factor that varies among the counties1.  For this analysis, we
grouped counties with similar fuel, emission standards, altitude, and inspection and maintenance (I/M)
programs.

The information used to group the counties was derived from the NMIM inputs used for the 2005 NEI
onroad and nonroad mobile sectors. For the onroad portion of the inventory estimates for the rule, including
all base and control scenarios, the current EPA highway mobile source emission model (MOVES) was used.
This required conversion of the NCD database parameters to a format consistent with MOVES.

The NCD also does not contain county specific information regarding vehicle populations and there are no
default values. Vehicle population data is a required input for MOVES when modeling on a county basis.
Using the technical guidance provided to states by EPA, the contractor generated appropriate estimates for
vehicle populations for use in the MOVES databases using the county specific VMT and national average
ratios of vehicle populations versus  vehicle VMT from the MOVES application. This method is described in
Section 3.3 of the document,  "Technical Guidance on the Use of MOVES2010 for Emission Inventory
Preparation in State Implementation Plans and Transportation Conformity" (EPA-420-B-10-023, April
2010), which is available on the EPA web site at: http://www.epa.gov/otaq/models/moves/index.htm

The grouping of counties uses a tree algorithm, which is conceptually simple. In the tree algorithm, all
counties are assigned to various categories.  Then by grouping counties within the same categories, you get
groups of counties that have the similar parameters.  Counties were sorted into their Petroleum
Administration for Defense Districts (PADDs).  PADD 1 is divided into three sub-PADD groupings and
each sub-group is treated as a separate PADD (la, Ib and Ic). Each state belongs to a PADD and all
counties in any state are within the same PADD.  Table 2-4 below shows the PADDs and the states within
each PADD.

The counties in each PADD were sorted into fuel groups using the January fuel properties and the July fuel
properties.  The fuel supply and fuel formulation data were taken from the 2005 fuels developed for the rule.
The fuel parameters used for grouping and the ranges of values used for the bins are described in Table 2-5.

Some states have adopted California highway vehicle emission standards or plan to adopt them. Since the
emission rates in these states will be different than in neighboring states, they must be modeled separately.
Also, because the implementation of California standards varies between these states, each state with
California standards must be modeled independently from the other states with California standards as well.
Each state with California standards will be treated separately when choosing representing counties.  Table
2-6 shows the states with California emission standards.

The counties in each PADD-fuel group were sorted into groups with and without I/M vehicle inspection
programs. I/M programs were determined using the 2005 calendar year entries in the IMCoverage table of
the MOVES database. The I/M category is the state in which the county resides.  All I/M programs within a
state were considered as a single program, even though each county may be administered separately and
have a different program design.

Altitude was also added as its own category. Altitude is a field in the County table of the
MOVESDB20101006 database. Counties are  either high (H) or low (L)  altitude based on the criteria set
                                                 10

-------
forth by EPA certification procedures (4,000 feet above sea level).  The result is a set of county groups with
similar fuel, emission standards, altitude and I/M program.  Then the county in with the highest VMT in each
group is chosen as the representing county. The categories are summarized below in Table 2-7.

Description
Petroleum Administration for Defense Districts (PADDs).
PADD 1 is divided into three sub-PADD groupings and
each sub-group is treated as a separate PADD (la, Ib and
Ic). Each state belongs to a PADD and all counties in any
state are within the same PADD.
Average gasoline fuel properties for January and July
2005, including RVP, sulfur level, ethanol fraction and
percent benzene.
Some states have adopted California highway vehicle
emission standards or plan to adopt them. Since
implementation of the standards varies, each state with
California standards is treated separately.
Counties were grouped within a state according to whether
or not they had an I/M program. All I/M programs within
a state were considered as a single program, even though
each county may be administered separately and have a
different program design.
Counties are either high or low altitude based on the
criteria set forth by EPA certification procedures (4,000
feet above sea level).
Using these criteria, a set of 106 counties were selected to represent the nation. Of these, only 103 were
needed to model the 48 states included in the air quality analysis inventory.  If MOVES runs were performed
for all U.S. counties and months, there would be 3141 counties (excluding AK and HI) times 12 months =
37,692 county-months. The MOVES runs for each representative county and fuel month were performed
independently of one another on different computer processors each accessing a MySQL database specific to
that run.

2.2.3  SMOKE-MOVES inputs
Both MOVES and SMOKE require meteorological data. The program met4moves takes gridded  hourly
meteorological data, the representative counties, and the representative fuel months and produces separate
meteorological products for MOVES and SMOKE. Met4moves uses the representative counties and fuel
months to determine the full range of meteorology in that county group.  For each representative county and
fuel month, it determines all the grid cells that fall within the corresponding counties in that county group for
the number of months that correspond to the fuel month2. The temperature range is then determined by
looking at the minimum and maximum temperature across all these grid cells for  all hours in that time
period. Relative humidity is calculated by taking an average over these same grid cells.
2 Spatial surrogates are used in determining which grid cells to pull in calculating the various meteorological statistics. These
spatial surrogates both map counties to grid cells. The spatial surrogates further limit the grid cells by determining whether some
of the grid cells should not be included in the calculation of temperature range. For example, if some of the county has no roads or
population, e.g. high mountains, then there is no reason to include it in the temperature range for onroad emissions.
                                                  11

-------
For rate-per-profile (RPP), SMOKE-MOVES uses the change in temperature over the day, the diurnal
profile, instead of the temperature at the hour of processing. Met4moves create a series of diurnal profiles
based on the extent of the temperature range and the size of the temperature bins. For MOVES, these diurnal
profiles will span the full range of temperatures for that representative county and fuel month.  For SMOKE
processing of RPP, met4moves creates a minimum and maximum temperature range for each county in the
domain. Note that these temperature ranges are county specific,  not based on the representative county or
county group. Met4moves can be run in daily or monthly mode for producing SMOKE input.  In monthly
mode, the temperature range is determined by looking at the range of temperatures over the whole month for
that specific county.  Therefore, there is one temperature range per county per month. While in daily mode,
the temperature range is determined by evaluating the range of temperatures in that county for that day. The
output for the daily mode is one temperature  range per county per day.  Typically, the SMOKE input
produced in monthly mode will have larger temperature ranges for each county than when it is run in daily
mode. For the MATS runs, met4moves was run in daily mode.

In addition to the lookup tables of emission rates produced by MOVES, SMOKE requires county VMT,
population,  and average speed by road type to calculate the necessary emissions for air quality modeling.
VMT by county and Source Classification Code (SCC) was developed using MOVES2010a and the National
County Database.  The National County Database (NCD20101201) has our most recent estimates of 2005
VMT and our best estimates of allocation of VMT from national to the county level.  Accordingly, for the
2005 base year, our estimates of VMT by county and SCC were taken directly from the NCD.

The average speeds provided to SMOKE for  each county were derived from the default national average
speed distributions found in the default MOVES2010a database AvgSpeedDistribution table. These average
speeds are the average speeds developed for the previous EPA highway vehicle emission factor model,
MOBILE6.  The same speed data was used for the base and future year cases.

In MOVES, there is a distribution of average speeds for each hour of the day for each road type.  The
average speeds in these distributions were used to calculate an overall average speed for each hour of the
day.  These hourly average speeds were weighted together using the default national average hourly vehicle
miles traveled (VMT) distribution found in the MOVES  default database HourlyVMTFraction table, to
calculate an average speed for each road type. This average speed by road type was provided to SMOKE for
each county.

2.2.4  Generating emission factors for SMOKE
After representative counties and fuel months were chosen, the met4moves script was executed to produce
the set of MOVES RunSpecs and meteorology tables that would ultimately generate a set of SMOKE lookup
tables encompassing the full range of temperatures for all the counties and months in  each group.  OTAQ
also provided VMT, population, and average speed tables for every county.

The onroad model-ready emissions were produced by running SMOKE-MOVES using  103 representative
counties and two fuel months. SMOKE-MOVES is a series of scripts and programs that 1) produce
meteorological data for MOVES (Met4Moves), 2) construct a set of MOVES RunSpecs that produce lookup
tables by temperature and average speed (runspec_generator), 3) process the MOVES lookup tables into a
SMOKE-ready format (moves2smkEF), and 4) runs SMOKE. The way that OTAQ used SMOKE-MOVES
differs somewhat from the way that SMOKE-MOVES was initially designed to be run.  The full  sequence of
events was the following:

   1)  OAQPS ran met4moves for a nation-wide 12 km grid. This generated the temperatures needed for the
       emission factor lookup tables and an average humidity for each county and month. The inputs to

                                               12

-------
       met4moves are the hourly gridded temperature and humidity generated by the meteorological model
       used for CMAQ along with the list of representative counties and fuel months. For each
       representative county and fuel-month, met4moves queries all the grid cells in all the represented
       county-months to find the full range of temperatures and profiles needed and averages the relative
       humidity.

   2)  OTAQ ran the runSpec_generator Perl script, (runspec_generator_v0.3_04Nov2010.plx).  The inputs
       to this process include the representative county list, fuel month list, temperature bin size (=10
       degrees here), and the outputs from met4moves. The runspec_generator script produced MOVES
       run-specifications that control how the MOVES run is configured, along zonemonthhour tables in
       CSV format.  Specifications were generated for the three types of MOVES processes: rate-per-
       distance (RPD), rate-per-profile (RPP), and rate-per-vehicle (RPV). Run specifications were
       generated as needed to simulate the range of conditions reflected in the meteorological inputs. For
       RPD and RPV, a series of run specifications were created for each representative county, one for
       each temperature bin covering the temperature ranges provided by the met4moves output. For RPP, a
       second series of run specifications were created for each representative county, one for each diurnal
       profile provided by the met4moves output.  The input data specific to each county were loaded into
       databases called "scaleinputdatabases", and the zonemonthhour tables were also loaded into
       databases.

   3)  OTAQ ran a tool to read the county databases,  the zonemonthhour databases, other user-supplied
       databases, and the run specifications. The tool implemented LEV programs into the specifications as
       appropriate and also modified the pollutant-process associations in the run specifications to meet the
       needs  of MATS. The tool then packaged the information into a form that could be used by the
       compute server.

   4)  OTAQ issued the command to kick off the required MOVES runs for each county and fuel month on
       the compute server.

   5)  Once the MOVES runs were complete, OTAQ ran the moves2smkEF postprocessor to reformat the
       MySQL tables into the emission factor tables in CSV format that is readable by the SMOKE
       movesmrg program. The postprocessor also performed additional calculations to  support SMOKE
       processing of CMAQ ready model emissions:  speciating HONO from NO and NO2, speciating the
       AE5 PM species (PEC, POC, PNO3, PSO4, PMFINE, and PMC for break and tire wear), and
       aggregating the detailed MOVES modes into 5 broader modes  (exhaust, evaporative, permeation,
       break wear, and tire wear)3

   6)  OAQPS downloaded the emission factors from the server and executed SMOKE programs to produce
       gridded, hourly, speciated emissions for CMAQ. See the next  section for details.

2.2.5  Running SMOKE for onroad mobile
Running SMOKE using emission factors (EF) from MOVES required  the development of a new set of
functionality.  The central SMOKE program that performs this new analysis is movesmrg which takes
activity data, meteorological data, and the EF to produce gridded emissions. SMOKE is run independently
for each of the three processes: rate-per-distance (RPD), rate-per-vehicle (RPV) and rate-per-profile (RPP).
3 The moves2smk postprocessor also corrects the extended idle emissions for RPV by merging in data from a separate national
extended idle run and replaces missing EF from RPD due to missing SCCroadtypes in some reference counties.
                                                13

-------
The emissions process RPD is for modeling the on-network emissions.  This includes the following modes:
vehicle exhaust, evaporation, permeation, break wear, and tire wear. For RPD, the activity data is monthly
VMT, monthly speed (SPEED), and hourly speed profiles for weekday versus weekend (SPDPRO)4. The
SMOKE program temporal takes vehicle and roadtype specific temporal profiles and distributes the monthly
VMT to day of the week and hour.  Movesmrg reads the speed data for that county and SCC and the
temperature from the gridded hourly data and uses these values to look-up the appropriate EF from the
representative county's EF table. It then multiplies this EF by temporalized VMT to calculate the emissions
for that grid cell and hour. This is repeated for each pollutant and SCC in that grid cell.

The emission process RPV is for modeling the off-network emissions.  This includes the following modes:
vehicle exhaust, evaporative, and permeation (????). For RPV, the activity data is vehicle population
(VPOP). Movesmrg reads the temperature from the gridded hourly data and uses the temperature plus SCC
and the hour of the day to  look up the appropriate EF from the representative county's EF table.  It then
multiplies this EF by the VPOP for that SCC and FIPS to calculate the emissions for that grid cell and hour.
This repeats for each pollutant and SCC in that grid cell.

The emission process RPP is for modeling the off-network emissions for parked vehicles. This includes the
mode vehicle evaporative  (fuel vapor venting).  For RPP, the activity data is VPOP. Movesmrg reads the
county based diurnal temperature range from met4moves output for SMOKE. It uses this temperature range
to determine the most similar idealized diurnal profile from the EF table using the temperature min and max,
SCC, and hour of the day.  It then multiplies this EF by the VPOP for that SCC and FIPS to calculate the
emissions for that grid cell and hour.  This repeats for each pollutant and SCC within the county. For more
details on processing RPD, RPV, and RPP in SMOKE, see:
http://www.smoke-model.Org/version3.0/html/ch02s08s04.html.

MOVES was run for a series of representative counties and fuel months. For each representative county and
fuel month, three EF tables were created: RPD, RPV, and RPP. SMOKE was run so that for each model day
it would read in a single EF table (based on the appropriate fuel month), process all the counties that are part
of the county group (i.e. are represented by that representative county), then read the next representative
county EF table, etc. After all days in the model year were looped over, SMOKE has generated a separate
set of daily  intermediate files for each of the emissions processes (RPD, RPV, and RPP). Post-processing
scripts were developed to integrate the process specific intermediate files into model-ready intermediate files
for the onroad sector. These files were on national 12km domain, to support the CMAQ runs they were
further processed to create an aggregated 36km sector specific model-ready file and 2  12km domains
(12EUS1 and 12WUS1).

2.3  Nonroad mobile sources (nonroad, alm_no_c3, seca_c3)
The nonroad sectors include a wide-range of mobile emission sources ranging from locomotives, marine
vessels,  construction and farming equipment to hand-held lawn tools. As discussed in Section 5, nonroad
upstream impacts also impact the post-EPAct/EISA/RFS2/reference case (anti-backsliding) reflecting
increased ethanol production resulting in fuel volume increases for locomotives and C1/C2 CMV emissions.

2.3.1 Emissions generated with the NONROAD model (nonroad)
Most nonroad emissions are were estimated using the EPA's NONROAD model, as run by the EPA's
NMIM.  NONROAD is EPA's model for calculating emissions from nonroad equipment, except for aircraft,
4 If the SPDPRO is available, the hourly speed takes precedence over the average speed in the SPEED inventory. Due to an
oversight, SPDPRO was not used in the base and future-years modeling. A later sensitivity was run including the SPDPRO input
for the base year which found that the use of hourly speed slightly increased the emissions for most pollutants (e.g. nationally NOX
showed a 0.8% increase, VOC showed a 1% increase, and PM25 showed a 3% increase).
                                               14

locomotives, and commercial marine vessels. The NONROAD Model and extensive documentation can be
found at http://www.epa.gov/otaq/nonrdmdl.htm.  NMEVI is a program that references a national database of
county-month data, writes county-month input files for NONROAD based on that data, runs NONROAD
once for every county and month requested by the user, and collects the results in an output database.
Information and downloads for NMIM can be found at http://www.epa.gov/otaq/nmim.htm. Rather than
running every county, NMIM is designed to run NONROAD for "representative counties" and to use
individual county activity to develop national inventories.  Inputs for NMIM runs were stored in the NMIM
County Database (NCD).  The NCD version is NCD20101201Tier3. This NCD is based on NCD20101201,
which is the version of the NCD that includes all updates from the 2008 National Emission Inventory
process: http://www.epa.gov/ttn/chief/net/2008inventory.html.

In particular, for this analysis, we made updates to the underlying fuel supply for the post EISA/EPAct
reference case. The NCD20101201Tier3 contained special versions of countyyearmonth, gasoline, and
diesel, which were copied into the standard versions of these tables in order to run the model.  The fuels in
NCD2010201Tier3 were developed from the fuels used for onroad vehicles, as described in Section 2.2.1.

Similarly, a special countymonthhour table that contained 2005 meteorology was copied into the standard
countymonthhour table. The use of the countymonthhour table for meteorology was selected by the RunSpec
setting use Yearly WeatherDataSelected="false." We also made a minor change for snowmobiles: the SCC
toxics table in the NMIM County Database (NCD) was updated to correct 1,3-butadiene exhaust emissions
for 2-stroke snowmobiles (SCC 2260001020), as shown in Table 2-8 below.  This correction addressed an
issue identified in air quality modeling for the RFS2 rule, where unexpected increases in ambient
concentrations were observed in rural areas during winter due to snowmobile emissions, available at:
http://www.epa.gov/otaq/renewablefuels/420rl0006.pdf  The increases were based on data from only three
engines, which showed unusually high 1,3-butadiene emissions with 10%  ethanol (Eth oxygenate). Other
data suggests that this increase is highly unlikely to be representative of the in-use fleet as a whole; thus
results were corrected to those in the "NCD20101201Tier3" column. In Table 2-but, Base Gasoline
represents cases where the fuel type is not Eth, MTBE or RFG.  Eth gas is used where the fuel contains
ethanol which is greater than or equal to 5% by volume or Ethyl Tertiary Butyl Ether (ETBE) is greater than
or equal to 5% by volume. MTBE gas is used where the fuel contains MTBE which is greater than or equal
to 12% by volume or Tertiary Amine Methyl Ether (TAME) is greater than or equal to 13% by volume.
Finally, RFG gas is used where the fuel is RFG and where the fuel contains oxygenate greater than 5% by
volume and where the fuel contains MTBE which is less than 12% by volume or TAME is less than  13% by
volume.

In addition, a special countymap table was developed to use representing counties in the NMIM runs.  The
algorithm for producing representing counties for NMIM was identical to that used for MOVES except that
ten degree temperature bins were added to the criteria.  The result was 293 representing counties.  Finally,
NMIM does not estimate ethanol emissions, so the inventory for this pollutant was from the chemical
speciation that is obtained by post-processing using SMOKE
                                                15

-------
2.3.1.1  Representing counties for NONROAD
"Representing counties" is a way of saving NMIM run time by grouping together similar counties and
generating emission factors by running the NONROAD Model for only one of those counties and then using
those emission factors for all the counties in the group. For this analysis, 293 county groups were developed.
The counties in each group were in the same state, had similar fuels in both summer and winter, and had
similar I/M programs. Since there are winter fuels and summer fuels, January was chosen as the fuel-month
to represent the seven months  October through April, and July was chosen to represent the five months May-
September. The total number of county-months for which NMIM runs needed to be performed was thus 293
times 12 months = 3,516 county-months for each scenario-year.  If NMIM runs were performed for all U.S.
counties and months, there would be 3141 counties (excluding AK and HI) times 12 months = 37,692
county-months.  Representing counties were chosen for NONROAD-Model NMIM runs by grouping
counties based on the characteristics  listed in Table 2-9.

District (PADD)

Grouping Criteria
All counties in a group must be in the same PADD.
Fuel bins were created for RVP, sulfur, benzene, and
ethanol. All counties in each group had all of these fuel
properties in the same bins for all twelve months.
Counties with I/M programs were grouped with other
counties with I/M programs in the same state.
All counties in the group must be in the same altitude
category (high or low).
All counties in the group must have similar temperatures, as
detailed below.
Nonroad inventories are not calculated on a grid basis, as the highway mobile sources were, so when running
NMIM for nonroad emissions, the representing counties must also account for temperatures. The
temperatures are taken from the 2005 calendar year values in the County YearMonthHour table of the
NCD20100602 NMIM database.  As shown in
                                               16

-------
Table 2-10, ten degree Fahrenheit (F) bins were created for min and max temperatures for each month.  All
counties in each group had all min and max temperatures for all twelve months in the same bins.  The lowest
interval includes all temperatures below -10 degrees F. The highest interval includes all temperatures above
100 degrees F.

Once counties were grouped, the representing county was chosen as the one with the highest VMT. The
same set of 293 county groups and representing counties was used for all years and scenarios.

2.3.1.2 Fuel inputs for NONROAD runs
For the nonroad mobile portion of the inventory estimate for the rule, the NMIM county database (NCD)
developed for the 2005 NEI, with one exception of the county-specific fuel properties, was used to calculate
nonroad emissions. Fuels were developed for MOVES (onroad mobile) for the MATS Rule (see Section
2.2) and were converted to NMIM fuels.  Practically, this means converting the fuelsupply and
fuelformulation tables from MOVES into the countyyearmonth, gasoline, and diesel tables in the NCD.
In 2005, onroad and nonroad gasoline formulations are assumed to be identical.

While MOVES allows  for multiple gasoline fuels, each with a market share, for a single county-month.  The
market shares always sum to one.  The NCD allows only one fuel per county month, but, for each of the four
oxygenates (ETOH, MTBE, TAME, and ETBE),  the NCD has columns for both volume percent and market
share. The sum of these market shares is less than or equal to one. If less than one, the remainder of the
market is non-oxygenated (conventional) gasoline.  When there are multiple MOVES gasoline fuels for a
single county-month, non-oxygenate MOVES fuel properties are multiplied by market share and summed to
produce the fuel property in the gasoline table. Individual non-ethanol oxygenates and California ethanol
occur in only one fuel per county-month in MOVES, so the volume and market share are transferred to the
appropriate columns for that oxygenate in NMIM. In states other than California, for multiple ethanol
volumes with volume percents less than 10, the product of market share and volume percent is averaged and
then divided by 10, resulting in a market share of E10.

2.3.1.3 NMIM runs
Table 2-11 shows the NMIM runs that were performed to generate the NONROAD Model county-month
results for both national inventories and air quality modeling inventories.

assumed that nonroad equipment would use only E10. The details of the fuels conversion from MOVES to

Description
This is identical to the official NONROAD2008,
(available at
http ://www. epa. sov/otaq/nonrdmdl . htm#model)
except it was modified to allow modeling of
emissions on El 5 fuels. The existing fuel effects
algorithm was retained.
This is the same as the official NMIM2008a
software, (available at
http://www.epa.sov/otaq/nmim.htm) except the
NONROAD model was updated to NROSb.
This is based on NCD20101201, which was
developed for the 2008 NEI. It was adapted to
model the desired scenarios.
Historical data for calendar year 2005 from the
National Climatic Data Center. County temperatures
were determined by weighting nearby temperature
stations by their distance from the population-based
centroid of each county.
2.3.2  Locomotives and commercial marine vessels (alm_no_c3, seca_c3)
The year 2005 emissions from these sources used for this rule are the same as they were for the Final
Rulemaking: Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-
Duty Engines and Vehicles signed on August 9, 2011 and available at
http://www.epa.gov/oms/climate/regulations.htm# 1 -2. and the Final Cross-State Air Pollution (CSAPR)
Rule:  ftp://ftp.epa.gov/EmisInventory/2005v4_2/transportrulefmal_eitsd_28jun2011.pdf. The procedures
for calculating emissions from locomotives and C1/C2 commercial marine were developed for the
Locomotive Marine Rule (2008) and are detailed in the RIA "Final Rule: Control of Emissions of Air
Pollution from Locomotives and Marine Compression-Ignition Engines Less Than 30 Liters per Cylinder",
published May 6, 2008 and republished June 30, 2008, and available at:
http://www.epa.gov/oms/locomotives.htmtf2008final.  The procedures used for calculating C3 commercial
marine emissions are those developed in the recent C3 "Final Rule: Control of Emissions from New Marine
Compression-Ignition Engines at or Above 30 Liters per Cylinder", published April 30, 2010 and available
at: http://www.epa.gov/oms/oceanvessels.htmtfcar-ems.

2.4  2005 point sources (ptipm and ptnonipm sectors)
Point sources are sources of emissions for which specific geographic coordinates (e.g., latitude/longitude) are
specified, as  in the case of an individual facility.  A facility may have multiple emission points, which may
be characterized as units such as boilers, reactors, spray booths, kilns, etc.  A unit may have multiple
processes (e.g., a boiler that sometimes burns residual oil and sometimes burns natural gas).  Note that this
section describes only NEI point sources within the contiguous United States.  The offshore oil platform
(othpt sector) and category 3 CMV emissions (seca_c3 sector) are also point source formatted inventories but
are unchanged for MATS modeling.  Discussion of the seca_c3  and othpt sector emissions can be found in
the Final CSAPR TSD referenced in Section 2.3.2.
                                               19

-------
After removing offshore oil platforms (othpt sector), we created two platform sectors from the remaining
2005v2 NEI point sources for input into SMOKE: the EGU sector - also called the Integrated Planning
Model (IPM) sector (i.e., ptipm) and the non-EGU sector - also called the non-IPM sector (i.e., ptnonipm).
This split facilitates the use of different SMOKE temporal processing and future-year projection techniques
for each of these sectors. The inventory pollutants processed through SMOKE for both ptipm and ptnonipm
sectors were: CO, NOX, VOC,  SO2, NH3, PMio, and PM2.5 and the following HAPs: HC1 (pollutant code =
7647010), and CL2 (code = 7782505). We did not utilize BAFM from these sectors as we chose to speciate
VOC without any use (i.e., integration) of VOC HAP pollutants from the inventory (integration is discussed
in detail in Section 3).

The ptnonipm emissions were provided to SMOKE as annual emissions. The ptipm emissions for the base
case were input to SMOKE as daily emissions. The ptipm emissions are unchanged  from those in the
2005v4.2 (basis for the Final CSAPR and Heavy Duty Greenhouse Gas (HDGHG) FRM) emission modeling
platform.  However, for the ptnonipm sector for all MATS scenarios, including year  2005 emissions, we
included additional known ethanol plants that were not previously included in 2005v4.2.  We also removed
all onroad refueling emissions as these were replaced with MOVES-based onroad refueling emissions
(discussed in Section 2.5.2).

2.4.1  Ethanol plants (ptnonipm)
We replaced all ethanol plants that OTAQ had supplied from the RFS2 rule -see Section 2.1.2 in the CSAPR
Final TSD- with those recently compiled for the 2005 case for MATS.  These plants represent a "Low
Ethanol" scenario needed to produce only 4 billion gallons of ethanol, essentially a scenario without a future
year RFS2 mandate (or MATS). All ethanol plants were assigned or corrected (after quality assurance
analyses) coordinates based on analysis using searches  of company web sites and Google Earth verification
for many sites. Emissions were calculated based on plant design capacity and emission factors based on fuel
type (e.g., coal, natural gas). Finally, because  benzene, acetaldehyde and formaldehyde (BAF) emissions
were directly computed for these sources, unlike the rest of the ptnonipm sector, we treated these ethanol
plants as VOC integrate sources. A summary of the ethanol plant emissions used in the 2005 scenario is
provided in Table 2-13.

2.5 2005 nonpoint sources (afdust, ag, avefire, nonpt)
The year 2005 area-source fugitive dust (afdust), agricultural animal and fertilizer NHs (ag), and average
(typical)-year fires (avefire) emissions are the same as those used in the CSAPR Final (2005v4.2) emission
modeling platform. Nonpoint sources that were not subdivided into the afdust, ag, or avefire sectors were
assigned to the "nonpt" sector, and most of these sources are also unchanged for MATS modeling.  The 2005
nonpoint sources that change are limited to portable fuel containers (PFCs) and onroad refueling.

2.5.1  Portable fuel containers
Year 2005 PFC emissions are unchanged from the CSAPR Final inventory except for the addition of ethanol.
Ethanol emissions were not provided for 2005, but were supplied for future year scenarios.  Therefore, we
scaled year 2017 reference case ethanol emissions by the ratio of 2005 to 2017 base total VOC emissions to
compute year 2005 ethanol emissions:

Ethanol_2005 = Ethanol_2017reference * (VOC_2005 / VOC_2017reference)

2.5.2  Onroad refueling
As mentioned in  Section 2.2, NEI-based onroad refueling emissions were replaced with estimates from the
revised version of EPA's Motor Vehicle Emissions Simulator (MOVES2010a) at the county level for all
twelve months.  This section describes how the emission inventories for refueling from on-road vehicles in
calendar years 2005 and 2017 for MATS reference and control cases were generated for air quality
modeling.  The refueling inventory includes emissions from spillage loss and displacement vapor loss. For
this analysis, the  refueling emissions were estimated using the revised version of EPA's Motor Vehicle
Emissions Simulator (MOVES2010a) at the county level for all twelve months.

In an effort to reduce MOVES runtime,  the "representing counties" approach was used instead of running
every single county in the lower 48 states. As described in Section 2.2 for onroad counties, we selected
representing counties  by grouping counties based on Petroleum Administration for Defense Districts
(PADD), fuel parameters, usage of California emission standards, Inspection/Maintenance programs, and
altitude. One additional parameter included in developing the representing counties for refueling was
temperature.

Temperature bins with increments often degrees F were created for the minimum and maximum
temperatures for  each month using the temperatures from the 2005 calendar year values in the
County YearMonthHour table of the NMIM County Database (NCD) NCD20100602 NMEVI database. All
counties in each group had min and max temperatures for all twelve months in the same temperature bins.

Once counties were grouped, the representing county was chosen as the one with the highest VMT, resulting
in total of 238 counties. The  same set of county groups and representing counties was used for all years and
scenarios.

MOVES was run in inventory mode for only the representing counties using the county-specific on-road
data, such  as vehicle miles travelled, fleet age distribution, speed distribution, and meteorology, available
from the NCD. The customized fuel inputs, discussed in Section 2.2.2.1, were used for each of the
representing counties.

The resulting refueling emission inventories for 238 representing counties in U.S. short tons were converted
to emission factors by dividing the inventory by the corresponding activity in each representing county.
Then, the calculated emission factors from the representing counties were applied to the represented counties
and multiplied by the  county-specific activity to generate the inventories for all counties.

2.6  Other sources (biogenics, othpt, othar, and othon)
All emissions from Canada, Mexico, and Offshore Drilling platforms (othpt, othar, and othon), and all non-
anthropogenic inventories (biogenics and ocean chlorine) are unchanged from the 2005v4.2 (used for the
Final CSAPR and HDGHG FRM) emissions modeling platform. The same emissions are used for all MATS
scenarios and years.

2.7  Emissions summaries for 2005 base case
Once developed, the emissions inventories were processed to provide the hourly, gridded emissions for the
model-species needed by CMAQ. Table 2-14 provides summaries of the 2005 U.S. emissions inventories
modeled for this rule by sector.  Table 2-15 and Table 2-16 provide state-level  summaries of SO2, and PM2.5
by sector. Note that the nonroad columns include emissions from traditional nonroad sources that are found
"on-land", along with commercial marine sources. The nonpoint columns include area fugitive dust,
agriculture, and other nonpoint emissions.

3    VOC Speciation Changes that Represent Fuel  Changes
A significant detail that is different in each of the MATS modeling cases than in the 2005v4.2 emissions
modeling is the VOC speciation profiles used to split total VOC emissions into the VOC model species
needed for CMAQ. In this section, we summarize the various speciation profile information used in
configuring the various cases.

A major change between the 2005v4.2 platform and the MATS base and future modeling is the integration of
ethanol for key sectors and specific inventories. In the previous platform, the inventories for specific sources
had benzene, acetaldehyde, formaldehyde and/or methanol (BAFM). These emissions would be integrated,
namely their emissions would come from the inventory not from speciating VOC. To prevent double
counting, BAFM would be removed from VOC, leaving the remainder (NONHAPVOC) to be speciated to
other components (i.e. non-BAFM species).  See section 3.1.2.1 of the 2005v4 platform for more details
                                             24

ftp://ftp.epa.gov/EtnisInventorv/2005v4/2005  emissions tsd __07jul2010.pdf.  In the MATS modeling, if
ethanol was present in the inventories, it would also be integrated.  To differentiate when a source was
integrating BAFM versus EBAFM (ethanol in addition to BAFM), the speciation profiles is referred to as an
"E-profile", for example pre-Tier 2 vehicles E10 gasoline exhaust speciation profile 8751 versus 875 IE. For
the onroad sector, ethanol is integrated for all emissions from gasoline vehicles. For the nonpt sector,
ethanol is integrated for refueling and portable fuel containers (PFCs).  In the future-year case, the nonpt
sector includes a cellulosic corn ethanol and biodiesel inventory (SCC 30125010) in which ethanol is
integrated. For fuel distribution operations associated with the bulk-plant-to-pump (btp) distribution, ethanol
is speciated from VOC because the nonpoint inventories do not include ethanol specifically.

The onroad sector has some additional changes to VOC speciation.  Instead of speciating VOC, SMOKE-
MOVES uses TOG instead of VOC.  Therefore, SMOKE does not need to convert VOC to TOG before
creating NONHAPTOG and performing additional speciation. A second change in VOC speciation is the
differentiation of a new mode. In previous platforms, onroad mobile emissions were divided into exhaust
and evaporative modes.  For the MATS base and future years, gasoline vehicle's evaporative mode is further
divided into permeation specific emissions and evaporative. Similar to evaporative and exhaust profiles,
these profiles change between the base and future year cases. Additional updates include headspace vapor
speciation utilizes a combination of the E10 headspace vapor profile and EO headspace vapor profile as
opposed to using solely EO for 20055, and a new Heavy  Duty Diesel vehicle exhaust mode profile for pre-
2007 model year (MY) vehicles that  replaces an older 2004-vintage medium-duty diesel profile.  See Table
3-1 for more details.

The VOC speciation approach is customized to account for the impact of fuel changes in the future year case.
These changes affect the onroad sector,  the nonroad sector, and parts of the nonpt and ptnonipm sectors.
These fuel changes and vehicle changes are implemented by using different VOC  profiles and combination
of profiles between the base and future cases.  The speciation changes from fuels in the nonpt sector are for
refueling, portable fuel containers (PFCs), and fuel distribution operations associated with the bulk-plant-to-
pump (btp) distribution.  The speciation changes from fuels in the ptnonipm sector include btp distribution
operations inventoried as point sources6. Refinery to bulk terminal (rbt) fuel distribution speciation does not
change across the modeling cases because this is considered upstream from the introduction of ethanol into
the fuel7.  Mapping of fuel distribution SCCs to btp and rbt emissions categories can be found in Appendix A
of the revised annual Renewable Fuel Standard (RFS2) Emissions Inventory for Air Quality Modeling
Technical Support Document (EPA Report No. 420-R-10-005, January 2010,
http://www.epa.gov/otaq/renewablefuels/420rl0005.pdf).

Table 3-1 summarizes the different profiles utilized for the fuel-related sources in each of the sectors for
2005 and the future year cases.  A comparison of the 2005v4.2 platform with the MATS 2005 case is also
included. Appendix A lists ancillary  input data set names used for MATS emissions.
5 This was an oversight in the 2005v4.2 platform corrected for this modeling effort.
6 VOC speciation is customized by using different speciation profiles in the base versus future year cases. For some sources
related to the mobile sector and fuel distribution, a combination of profiles are specified by county, month and mode (e.g. exhaust,
evaporative, permeation). SMOKE calculates a resultant profile by calculating the fraction of each profile by month, county, and
mode. The GSPRO_COMBO ancillary file controls this feature in SMOKE. The GSPRO_COMBO file represents the county
specific mixture of fuels, for example the mixture of E10 and EO.  For the nonpt sector, a further complication in developing the
GSPRO_COMBO is differentiating the sources that integrate ethanol (i.e. use E-profiles) and those that do not integrate ethanol.
By using the mode for refueling (RFL	VOC) and PFC (EVP	VOC), these ethanol integrated sectors can be differentiated from
btp (VOC).
7 We also identified bulk plant storage (bps) as an upstream source that is pre-addition of ethanol and uses the same speciation
profile as rbt.

4   2017  Reference Case
The 2017 reference case represents the future, including the implementation of emissions impacts of the fuel
volumes mandated by the 2005 EPAct and 2007 EISA and finalized in the RFS2 program. The reference
case includes MSAT2 and LDGHG but does not include HDGHG impacts.  The 2017 reference case
assumes 21.6 billion gallons of renewable fuels (24 billion ethanol-equivalent gallons due to volume
increases of ethanol), with 17.8 billion gallons of E10 and E15, 1.5 billion gallons of biodiesel, 0.2 billion
gallons of renewable diesel, and 2.2 billion gallons of cellulosic diesel. The fuel changes required upstream
emissions estimates and adjustments in addition to the downstream changes to onroad and nonroad mobile
source emissions.  For nonroad mobile sources, onroad mobile including refueling sources, OTAQ-generated
emissions were provided to reflect the reference case fuels.

The 2017 reference case uses many of the same growth and control assumptions as those  for the Final Cross-
State Air Pollution Rule (CSAPR), because other than onroad mobile, nonroad mobile, onroad refueling,
PFC, and ethanol plant sources, both MATS and CSAPR use the same 2005v4.2-based emissions
inventories. There are some differences between the 2012 and 2014 base case projections in CSAPR and the
2017 reference case for MATS:

    1) 2017 includes some additional controls that were promulgated after 2014, (e.g., post-2014 consent
      decrees and fuel sulfur rules in a couple of states).
   2) Growth factors for several sources are year-specific; so while the methodology is the same as
      CSAPR, the future year emissions estimates differ (e.g., oil and gas in a couple states, residential
      wood combustion).
   3) Onroad refueling uses year and scenario-specific (i.e., reference) MOVES emissions for all MATS
      modeling, rather than NEI emissions.
   4) There is a new dataset of ethanol plants that replace a limited set of NEI ethanol plants in 2005v4.2-
      based CSAPR 2012 and 2014 projections.  These MATS reference case emissions are the same for
      the 2005 and 2017 base case.
   5) Minor errors identified after CSAPR modeling was complete were fixed (e.g, we include agricultural
      dust projections for the couple of states that provided point source farms).

The remainder of Section 4 is very similar to Section 4 in the CSAPR emissions modeling TSD, available
from ftp://ftp.epa.gov/EmisInventory/2005v4_2/transportrulefinal_eitsd_28jun2011.pdf. but with the updates
described above.

The future case projection methodologies vary by sector.  For EGU emissions (ptipm sector), the emissions
reflect state rules and federal consent decrees through December 1, 2010. For onroad mobile sources, all
national measures for which data were available at the time of modeling have been included. The future case
scenarios reflect projected economic changes and  fuel usage for EGU and mobile sectors. For nonEGU
point (ptnonipm sector) and nonpoint stationary sources (nonpt, ag, and afdust sectors), local control
programs that might have been necessary for areas to attain the 1997 PM2.5 NAAQS annual standard, 2006
PM NAAQS (24-hour) standard, and the 1997 ozone NAAQS are generally not included  in the future base-
case projections for most states. One exception are some NOx and VOC reductions associated with the New
York, Virginia, and Connecticut State Implementation Plans (SIP), which were added as part of the
comments received from the CSAPR and a larger  effort to start including more local control information on
stationary non-EGU sources; this is described further in Section 4.2.  The following bullets summarize the
                                               28

-------
projection methods used for sources in the various sectors, while additional details and data sources are given
in Table 4-1.

   •   IPM sector (ptipm):  Unit-specific estimates from IPM, version 4.10.
   •   Non-IPM sector (ptnonipm):  Projection factors and percent reductions reflect CSAPR (Transport
       Rule) comments and emission reductions due to control programs, plant closures, consent decrees
       and settlements, and 1997 and 2001 ozone State Implementation Plans in NY, CT, and VA. We also
       used projection approaches for point-source livestock, and aircraft that are consistent with projections
       used for the sectors that contain the bulk of these emissions.  Terminal area forecast (TAP) data
       aggregated to the national level were used for aircraft to account for projected changes in
       landing/takeoff activity. Year-specific speciation was applied to some portions of this sector and was
       discussed in Section 3.
   •   Average fires sector (avefire): No growth or control.
   •   Agricultural sector (ag): Projection factors for livestock estimates based on expected changes in
       animal population from 2005 Department of Agriculture data; no growth or control for NH3
       emissions from fertilizer application.
   •   Area fugitive dust sector (afdust): Projection factors for dust categories related to livestock estimates
       based on expected changes in animal population; no growth or control for other categories in this
       sector.
   •   Remaining Nonpoint sector (nonpt): Projection factors that implement CSAPR Proposal comments
       and reflect emission reductions due to control programs.  Residential wood combustion projections
       based on growth in lower-emitting stoves and a reduction in higher emitting stoves.  PFC projection
       factors reflecting impact of the final Mobile Source Air Toxics (MSAT2) rule and include ethanol
       emissions. Gasoline stage II onroad refueling emissions obtained directly from MOVES. Oil and gas
       projection estimates are provided for the non-California Western Regional Air Partnership (WRAP)
       states as well as Oklahoma and Texas. Year-specific speciation was applied to some portions of this
       sector and was discussed in Section 3.
   •   Nonroad mobile sector (nonroad): Same version of the NONROAD2008a, including same set of 293
       county groups and representing counties as the 2005 base case. Future-year equipment  population
       estimates and control programs (final locomotive-marine and small spark ignition) to 2017 are
       included. The only differences between the MATS future case runs are the fuels used, specifically,
       the ratio of E10 and E15 fuels. Year-specific speciation was applied to some  portions of this sector
       and is discussed in Section 3.
   •   Locomotive, and non-Class 3 commercial marine sector (alm_no_c3): Projection factors for Class 1
       and Class 2 commercial marine and locomotives which reflect CSAPR Proposal comments and
       activity growth and final locomotive-marine controls.
   •   Class 3 commercial marine vessel sector (seca_c3): Base-year 2005 emissions grown and controlled
       to 2017, incorporating CSAPR Proposal comments and controls based on Emissions Control Area
       (EGA) and International Marine Organization (IMO) global NOx and SO2 controls.
   •   Onroad mobile sector uses a version MOVES developed for the Tier 3 Proposal that incorporates new
       car and light truck greenhouse gas emissions standards (LDGHG) affecting model years 2012 and
       later (published May 7, 2010). These emissions also include RFS2 fuels. VOC speciation uses
       different future-year values to take into account both the increase in ethanol use, and the existence of
       Tier 2 vehicles that use a different speciation profile. This sector includes all  non-refueling onroad
       mobile emissions (exhaust, evaporative, brake wear and tire wear modes).  SMOKE-MOVES was
       used in a similar configuration as the 2005 base case to apportion MOVES  emissions factors into
       hourly gridded temperature-adjusted emissions.

                                                29

Other nonroad/nonpoint (othar): No growth or control.
Other onroad sector (othon): No growth or control.
Other nonroad/nonpoint (othar): No growth or control.
Other point (othpt): No growth or control.
Biogenic: 2005 emissions used for all future-year scenarios.
                                          30

-------
Table 4-1 summarizes the control strategies and growth assumptions by source type that were used to create
the 2017 reference-case emissions from the 2005v4.2 base-case inventories.  These future year base case
projections and controls are also included in the MATS reference and control cases. All Mexico, Canada,
and offshore oil emissions are unchanged in all future cases from those in the 2005 base case.

Lists of the control, closures, projection packets (datasets) used to create the MATS 2017 future case
inventories from the 2005 MATS base case are provided in Appendix C.

The remainder of this section is organized either by source sector or by specific emissions category within a
source sector for which a distinct set of data were used or developed for the purpose of projections for the
MATS Rule.  This organization allows consolidation of the discussion of the emissions categories that are
contained in multiple sectors, because the data and approaches used across the sectors are consistent and do
not need to be repeated. Sector names associated with the emissions categories are provided in parentheses.

4.1  Stationary source projections:  EGU sector (ptipm)
The future-year data for the ptipm sector used in the air quality modeling were created using version 4.10
Final of the Integrated Planning Model (IPM) (http://www.epa.gov/airmarkt/progsregs/epa-ipm/index.html).
The IPM is a multiregional, dynamic, deterministic linear programming model of the U.S. electric power
sector. Version 4.10 Final reflects federal and state rules and binding, enforceable consent decrees through
December of 2010. The 2017 IPM emissions reflect the CSAPR as finalized in July 2011.  The reference
case, also known as the future year baseline, emissions do not reflect the final Mercury and Air Toxics
(MATS)  rule, but the control case emissions do reflect the rule.  Neither case reflects the Boiler MACT
regulatory assumptions.

Version 4.10 Final reflects state rules and consent decrees through December 1, 2010, information obtained
from the  2010 Information Collection Request (ICR), and information from comments received on the IPM-
related Notice of Data Availability (NOD A) published on September 1, 2010. Notably, IPM 4.1 Final
included  the addition of over 20 GW of existing Activated Carbon Injection (ACI) for coal-fired EGUs
reported to EPA via the ICR. Additional unit-level updates that identified existing pollution controls (such as
scrubbers) were also made based  on the ICR and  on comments from the IPM NOD A. Units with SO2 or
NOX advanced controls (e.g., scrubber, SCR) that were not required to run for compliance with Title IV,
New Source Review (NSR), state settlements, or  state-specific rules were modeled by IPM to either operate
those controls or not based on economic efficiency parameters. The IPM run for the reference case modeled
with CMAQ assumed that 100% of the HC1 found in the coal was emitted into the  atmosphere. However, in
the  final IPM results for the rule,  neutralization of 75% of the available HC1 was included based on recent
findings.

Further details on the reference case EGU emissions inventory used for this rule can be found in the IPM
v.4.10 Documentation, available at http://www.epa.gov/airmarkets/progsregs/epa-ipm/transport.html. The
reference case modeled in IPM for this rule includes estimates of emissions reductions that will result from
the  Cross-State Air Pollution Rule. However, reductions from the Boiler MACT rule were not represented
this modeling because the rule was stayed at the time the modeling was performed. A complete list of state
regulations, NSR settlements, and state settlements included in the IPM modeling is given in Appendices 3 -
2, 3-3, and 3-4 beginning  on p. 68 of http://www.epa.gov/airmarkets/progsregs/epa-
ipm/CSAPR/docs/DocSuppv410_FTransport.pdf For the 2017 reference case EGU emissions, the IPM
outputs for 2020, which are also representative of the year 2017,  were used. These emissions were very
similar to the year 2015 emissions output from the same IPM modeling case.

Directly emitted PM emissions (i.e., PM2.5 and PMio) from the EGU sector are computed via a post
processing routine which  applies  emission factors to the IPM-estimated fuel throughput based on fuel,
configuration and controls to compute the filterable and condensable components of PM. This methodology
is documented in the IPM CSAPR TSD.

4.2 Stationary source projections: non-EGU sectors (ptnonipm, nonpt, ag,
     afdust)
To project U.S. stationary sources other than the ptipm sector, we applied growth factors and/or controls to
certain categories within the ptnonipm, nonpt, ag and afdust platform sectors. This subsection provides
details  on the data and projection methods used for these sectors. The MATS future year scenarios also
required obtaining and preprocessing numerous other inputs that we received directly from OTAQ.

In estimating future-year emissions, we assumed that emissions  growth does not track with economic growth
for many stationary non-IPM sources. This "no-growth" assumption is based on an examination of historical
emissions and economic data. More details on the rationale for this approach can be found in Appendix D of
the Regulatory Impact Assessment for the PM NAAQS rule (EPA, 2006).

The starting point for projecting the 2005 MATS emissions was to use similar emission projection
methodologies as used for the 2005v4.2 platform for the Final CSAPR, which incorporated responses to
public comments on the modeling inventories. The 2012 and 2014 projection factors developed for the
CSAPR (see http://www.epa.gov/ttn/chief/emch/index.html#final) were updated to reflect year 2017.

Year-specific projection factors for years 2017 were created. Growth factors (and control factors) are
provided  in the following sections where feasible. However, some sectors used growth or control factors
that varied geographically and their contents could not be provided in the following sections (e.g., gasoline
distribution varies by state and pollutant and has hundreds of records).

Table 4-2 lists the stationary non-EGU inputs and projection factors that were applied to account for the year
2017 RFS2 mandate impacts on emissions to the reference case. These inputs are  discussed  in more detail in
Section 4.2.1 through Section 4.2.9. All other stationary non-EGU projections, controls and plant closure
information not related to the RFS2 impacts are  discussed in Section 4.2.10 through Section 4.2.13.  All
stationary non-EGU emissions in the 2017 reference case are unchanged in the 2017 control case (see
Section 5); therefore, we will simply note that these emissions are "year 2017" rather than the more
cumbersome "year 2017 reference  case".

4.2.1  Ethanol plants (ptnonipm)
As discussed in Section 2.4.1, we replaced all corn ethanol plants that OTAQ had supplied from the RFS2
rule -see Section 2.1.2 in the CSAPR Final TSD- with those recently compiled for 2005 and a year 2017
without the RFS2 mandate (not separately modeled for this rule). Additional ethanol plants cited for
development in support of increased ethanol production for RFS2 are the cause for the increased number of
facilities and emissions in the reference case. Table 4-3 provides the summaries for the corn ethanol plants
in the 2017 reference case.

4.2.2  Biodiesel plants (ptnonipm)
OTAQ developed an inventory of existing biodiesel plants for 2017 that were sited at existing plant locations
in support of producing biodiesel fuels for the RFS2 mandate. The RFS2 calls for 1.45 billion gallons per
year (Bgal) of biodiesel fuel production by year 2017. Only plants with current production capacities were
assumed to be operating in 2017.  Total plant capacity at these existing facilities is limited to just over 1
Bgal.  There was no attempt to site future year plants to account for the need to match biodiesel production
needed for RFS2. Therefore, OTAQ applied a scalar adjustment (of 1.41) to each individual biodiesel plant
to match the 2017 production target of 1.45 Bgal. Once facility-level production capacities were scaled,
emission factors were applied based on an assumed natural gas combustion process.  Inventories were
                                                37

4.2.3  Portable fuel containers (nonpt)
OTAQ provided year 2017 PFC emissions that include estimated Reid Vapor Pressure (RVP) and oxygenate
impacts on VOC emissions, and more importantly, large increases in ethanol emissions from RFS2. These
emission estimates also include refueling from the NONROAD model for gas can vapor displacement,
changes in tank permeation and diurnal emissions from evaporation. Because these PFC inventories contain
ethanol, we developed  a VOC E-profile that integrated ethanol, see Section 3 for more details. Emissions for
2017 are provided in Table 4-5.

4.2.4  Cellulosic fuel production (nonpt)
OTAQ developed county-level inventories for cellulosic diesel and cellulosic ethanol production for 2017 to
satisfy RFS2 production. The methodology for building cellulosic plant emissions inventories is fairly
similar conceptually to that for building the biodiesel plant inventories. First, we assume that cellulosic
diesel and cellulosic ethanol are produced in the same counties where current production capacity exists,
based on RFS2 FRM inventories.  Total county production capacities was over 16 Bgal; therefore, OTAQ
applied a scalar adjustment (of 0.246) to each counties production capacity to match the 2017 production
target of 3.93 Bgal (2.2 Bgal diesel and 1.69Bgal ethanol).  Once county-level cellulosic production
capacities were scaled down to match the 2017 target, emission factors were applied based on an assumed
natural gas combustion process.

We had no refined information on potential VOC speciation differences between cellulosic diesel and
cellulosic ethanol sources.  Therefore, we summed up cellulosic diesel and cellulosic ethanol sources and
used the same SCC (30125010: Industrial Chemical Manufacturing, Ethanol by Fermentation production) for
VOC speciation as was used for corn ethanol plants.  However, these cellulosic inventories contain ethanol;
therefore we developed a VOC E-profile that integrated ethanol, see Section 3 for more details.

4.2.5  Ethanol transport and distribution (nonpt)
OTAQ developed county-level inventories for ethanol transport and distribution for 2017 to account for
losses for the processes such as truck, rail and waterways loading/unloading and intermodal transfers such as
highway-to-rail, highways-to-waterways, and all other possible combinations of transfers. Emission rates
were applied based on June 2008 AP-42 factors and ethanol versus gasoline vapor mass equations. These
emissions  are entirely evaporative and therefore limited to VOC and are summarized in Table 4-7. The
leading descriptions are "Industrial Processes; Food and Agriculture; Ethanol Production" for each SCC.

4.2.6  Onroad refueling (nonpt)
As discussed in Section 2.5.2, the refueling inventory includes gasoline and diesel fuel emissions from
spillage loss and displacement vapor loss. For this analysis, the refueling emissions were estimated using the
revised version of EPA's Motor Vehicle Emissions Simulator (MOVES2010a) at the county level for all
twelve months. The same set of representative counties and temperatures were used for all MATS scenarios.
VMT, fleet age distribution and speed distribution were developed for 2017. Because these refueling
inventories contain ethanol, we developed a VOC E-profile that integrated ethanol, see Section 3 for more
details.  A summary of the 2017 onroad mobile refueling emissions is provided in
                                                42

4.2.7  Refinery adjustments (ptnonipm)
Refinery emissions were adjusted for changes in fuels due to the RFS2 mandate.  These adjustments were
provided by OTAQ and impact processes such as process heaters, catalytic cracking units, blowdown
systems, wastewater treatment, condensers, cooling towers, flares and fugitive emissions. The impact of the
RFS2-based reductions is shown in Table 4-9.

Emissions changes in the transport of changing fuels from the RFS2 mandate impact several processes
including bulk plant storage (BPS), refinery to bulk terminal (RBT) and bulk terminal to pump (BTP). These
impacts, provided by OTAQ, result in approximately 15,000 tons of VOC reductions in 2017 for these
processes.

4.2.9  Upstream agricultural adjustments (afdust, ag, nonpt, ptnonipm)
Changes in domestic biofuel volumes, resulting from the RFS2 fuels mandate, impact upstream agricultural-
related source categories in several emissions modeling sectors. These source categories include fertilizer
application, pesticide application and livestock waste (NHs only), agricultural tilling, unloading and livestock
dust (PM only) and fertilizer production mixing and blending, pesticide production and agricultural burning
(all pollutants). As seen in Table 4-10, the cumulative impact of these source-specific changes is a net
increase in emissions for upstream agricultural sources.

4.2.10       Livestock emissions growth (ag, afdust)
Growth in ammonia (NH3) and dust (PMio and PM2.5) emissions from livestock in the ag, afdust and
ptnonipm sectors was based on projections of growth in animal population. Table 4-1 liable 4-11 provides
the growth factors from the 2005 base-case emissions to all MATS year 2017 scenarios for animal categories
applied to the ag, afdust, and ptnonipm sectors for livestock-related SCCs.

Except for dairy cows and turkey production, the animal projection factors are derived from national-level
animal population projections from the U.S.  Department of Agriculture (USD A) and the Food and
Agriculture Policy and Research Institute (FAPRI). For dairy cows and turkeys, we assumed that there
would be no growth in emissions. This assumption was based on an analysis of historical trends in the
number of such animals compared to production rates.  Although productions rates have increased, the
number of animals has declined.  Thus, we do not believe that production forecasts provide representative
estimates of the future number of cows and turkeys; therefore, we did not use these forecasts for estimating
future-year emissions from these animals.  In particular, the dairy cow population is projected to decrease in
the future as it has for the past few decades; however, milk production will be increasing over the same
period. Note that the ammonia emissions from dairies are not directly related to animal population but also
nitrogen excretion.  With the cow numbers going down  and the production going up we suspect the excretion
value will be changing, but we assumed no change because we did not  have a quantitative estimate.

The inventory for livestock emissions used 2002 emissions values therefore, our projection method projected
from 2002 rather than from 2005.

Appendix E in the 2002v3 platform documentation provides the animal population data and regression
curves used to derive the growth factors:

sectors to the animal categories in Table 4-11 Table 4-11.

4.2.11       Residential wood combustion growth (nonpt)
We projected residential wood combustion (RWC) emissions based on the expected increase in the number
of low-emitting wood stoves and the corresponding decrease in other types of wood stoves. As newer,
cleaner woodstoves replace older, higher-polluting wood stoves, there will be an overall reduction of the
emissions from these sources.  The approach cited here was developed as part of a modeling exercise to
estimate the expected benefits of the woodstoves change-out program (http://www.epa.gov/burnwise).
Details of this approach can be found in Section 2.3.3 of the PM NAAQS Regulatory Impact Analysis (EPA,
2006).
The specific assumptions we made were:
                                               45

-------
    •   Fireplaces, source category code (SCC)=2104008001: increase 1%/year
    •   Old woodstoves,  SCC=2104008002, 2104008010, or 2104008051: decrease 2%/year
    •   New woodstoves, SCC=2104008003, 2104008004, 2104008030, 2104008050, 2104008052 or
       2104008053: increase 2%/year

For the general woodstoves and fireplaces category (SCC 2104008000) we computed a weighted average
distribution based on 19.4% fireplaces,  71.6% old woodstoves, 9.1% new woodstoves using 2002v3
Platform missions for PM2.5.  These fractions are based on the fraction of emissions from these processes in
the states that did not have the "general woodstoves and fireplaces" SCC in the 2002v3 NEI. This approach
results in an overall decrease of 1.056% per year for this source category.

We discovered an interpolation error in the year 2017 projection factors for RWC after air quality modeling.
Table 4-12 presents the projection factors used to project the 2005 base case (2002  emissions) for RWC,
including these 2017 errors. Table 4-13shows the national impact (tons) of the 2017 projection factor error.

4.2.12      Aircraft growth (ptnonipm)
These 2005 point-source emissions are projected to future years by applying activity growth using data on
itinerant (ITN) operations at airports. The ITN operations are defined as aircraft take-offs whereby the
aircraft leaves the airport vicinity and lands at another airport, or aircraft landings whereby the aircraft has
arrived from outside the airport vicinity.  We used projected ITN information available from the Federal
Aviation Administration's (FAA) Terminal Area Forecast (TAP) System:
http://www.apo.data.faa.gov/main/taf.asp (publication date January 2010).  This information is available for
approximately 3,300 individual airports, for all years up to 2030. We aggregated and applied this
information at the national level by summing the airport-specific (U.S. airports only) ITN operations to
                                                46

-------
national totals by year and by aircraft operation, for each of the four available operation types: commercial,
general, air taxi and military.  We computed growth factors for each operation type by dividing future-year
ITN by 2005-year ITN.  We assigned factors to inventory SCCs based on the operation type.

The methods that the FAA used for developing the ITN data in the TAP are documented in:
http://www.faa.gov/data_research/aviation/aerospace_forecasts/2009-
2025/media/2009%20Forecast%20Doc.pdf

Table 4-14 provides the national growth factors for aircraft; all factors are applied to year 2005 emissions.
For example, year 2017 commercial aircraft emissions are 12.88% higher than year 2005 emissions.  The
same aircraft factors were used for each of the year-specific scenarios: low-ethanol, reference and control.

We did not apply growth factors to any point sources with SCC 27602011 (Internal Combustion Engines;
Rotary Wing Aircraft L & TO Exhaust; Commercial; Jet Engine: Jet A) because the facility names
associated with these point sources appeared to represent industrial facilities rather than airports. This SCC
is only in one county, Santa Barbara, California (State/County FIPS 06083).

None of our aircraft emission projections account for any control programs. We considered the NOx
standard adopted by the International Civil Aviation Organization's (ICAO) Committee on Aviation
Environmental Protection (CAEP) in February 2004, which is expected to reduce NOx by approximately 2%
in 2015 and 3% in 2020. However, this rule, signed July 2011 (see http://www.epa.gov/otaq/aviation.htm).
was not adopted as an EPA (or U.S.) rule prior to MATS modeling; therefore, the effects of this rule were
not included in the future-year emissions projections.

4.2.13       Stationary  source control programs, consent decrees & settlements, and
       plant closures (ptnonipm,  nonpt)
We applied emissions reduction factors to the 2005 emissions for particular sources in the ptnonipm and
nonpt sectors to reflect the impact of stationary-source control programs including consent decrees,
settlements, and plant closures.  Some of the controls described in this section were obtained from comments
on the CSAPR proposal. Detailed summaries of the impacts of the control programs are provided in
                                               47

Appendix D of the CSAPR TSD:
ftp://ftp.epa.gov/EmisInventory/2005v4 2/transportrulefmal eitsd appendices 28jun2011.pdf.
Controls from the NOx SIP call were assumed to have been implemented by 2005 and captured in the 2005
base case (2005v2 point inventory). This assumption was confirmed by review of the 2005 NEI that showed
reductions from Large Boiler/Turbines and Large Internal Combustion Engines in the Northeast states
covered by the NOx SIP call. The future-year base controls consist of the following:

    •   We did not include MACT rules where compliance dates were prior to 2005, because we assumed
       these were already reflected in the 2005 inventory.  The EPA OAQPS Sector Policies and Programs
       Division (SPPD) provided all controls information related to the MACT rules, and this information is
       as consistent as possible with the preamble emissions reduction percentages for these rules.

    •   Various emissions reductions from the CSAPR comments, including but not limited to: fuel
       switching at units, shutdowns, future-year emission limits, ozone SIP VOC controls for some sources
       in Virginia and Connecticut, and state and local control programs.

    •   Evolutionary information gathering of plant closures (i.e., emissions were zeroed out for future years)
       were also included where information indicated that the plant was actually closed after the 2005 base
       year and prior to CSAPR and MATS modeling that began in the spring of 2011. We also applied unit
       and plant closures received from the CSAPR comments.  However, plants projected to close in the
       future (post-2010) were not removed in the future years because these projections can be inaccurate
       due to economic improvements.  We also applied cement kiln (unit) and cement plant closures
       discussed later in Section 4.2.6.1. More detailed information on the overall state-level impacts of all
       control programs and projection datasets, including units and plants closed in the 2017 reference case
       ptnonipm inventories are provided in Appendix D of the Final CSAPR TSD:
       ftp://ftp.epa.gov/EmisInventory/2005v4_2/transportrulefinal_eitsd_appendices_28jun2011.pdf.  The
       magnitude of all unit and plant closures on the non-EGU point (ptnonipm) sector 2005 base-case
       emissions is shown in Table 4-15 below. These same reductions are seen in all MATS future year
       scenarios.

       In addition to plant closures, we included the effects of the Department of Justice Settlements and
       Consent Decrees on the non-EGU (ptnonipm) sector emissions. We also included estimated impacts
       of HAP standards per Section 112, 129 of the Clean Air Act on the non-EGU (ptnonipm) and
       nonpoint (nonpt) sector emissions, based on expected CAP co-benefits to sources in these sectors.

       Numerous controls have compliance dates beyond 2008; these include refinery and the Office of
       Compliance and Enforcement (OECA) consent decrees, Department of Justice (DOJ) settlements, as
       well as most national VOC MACT controls. Additional OECA consent decree information is
       provided in Appendix B of the Proposed Toxics Rule TSD:

   •   Criteria air pollutant (cap) reductions a cobenefit to RICE NESHAP controls, including SC>2 RICE
       cobenefit controls.

   •   We applied New York State Implementation Plan available controls for the 1997 8-hour Ozone
       standard for non-EGU point and nonpoint NOx and VOC sources based on NY State Department of
       Environmental Conservation February 2008 guidance. These reductions are found in Appendix J in:
       http://www.dec.nv.gov/docs/air_pdf/NYMASIP7fmal.pdf See Section 3.2.6 in the CSAPRTSD:
       ftp://ftp.epa.gov/EmisInventory/2005v4_2/transportrulefinal_eitsd_28jun2011.pdf.

Most of the control programs were applied as replacement controls, which means that any existing percent
reductions ("baseline control efficiency") reported in the NEI were removed prior to the addition of the
percent reductions due to these control programs. Exceptions to replacement controls are "additional"
controls, which ensure that the controlled emissions match desired reductions regardless of the baseline
control efficiencies in the NEI.  We used the "additional controls" approach for many permit limits,
settlements and consent decrees where specific plant and multiple-plant-level reductions/targets were desired
and at municipal waste landfills where VOC was reduced 75% via a MACT control using projection factors
ofO.25.

4.2.13.1      Reductions from the Portland  Cement NESHAP (ptnonipm)
As indicated in Table 4-1, the Industrial Sectors  Integrated Solutions (ISIS) model (EPA, 2010) was used to
project the cement industry component of the ptnonipm emissions modeling sector to 2013. There were no
future year estimates for 2017, so 2013 estimates were used for all future year MATS modeling scenarios.
This approach provided reductions of criteria and hazardous air pollutants, including mercury.  The ISIS
cement emissions were developed in support for the Portland Cement NESHAPs and the NSPS for the
Portland cement manufacturing industry.

The ISIS model produced a Portland Cement NESHAP policy case  of multi-pollutant emissions for
individual cement kilns  (emission inventory units)  that were relevant for years 2013 through 2017. These
ISIS-based emissions included information on new cement kilns, facility and unit-level closures, and updated
policy case emissions at existing cement kilns. The units that opened or closed before 2010 were included in
the projections as were the ISIS-based policy case predictions of emissions reductions and activity growth.

The ISIS model results for the future  show a continuation of the recent trend in the cement  sector of the
replacement of lower capacity, inefficient wet and long dry kilns with bigger and more efficient preheater
and precalciner kilns. Multiple regulatory requirements such as the NESHAP and NSPS currently apply to
the cement industry to reduce CAP and HAP emissions. Additionally, state and local regulatory
requirements might apply to individual cement facilities depending  on their locations relative to ozone and
PM2.5 nonattainment areas. The ISIS model provides the emission reduction strategy that balances: 1)
optimal (least cost) industry operation, 2) cost-effective controls to meet the demand for cement, and 3)
emission reduction requirements over the time period of interest.

The Boiler MACT ICR collected data on existing controls. We used an early version of a data base

0788) which is posted under the Technical Information for the Boiler MACT major source rule
(http ://www.epa.gov/ttn/atw/boiler/boilerpg.html). We extracted all  non-EGU stationary (ptnonipm)
controls that were installed after 2005, determined a percent reduction, and verified with source owners that
these controls were actively in use. In many situations we learned that the controls were on site but were not
in use. A summary of the plant-unit specific reductions that were verified to be actively in use are
summarized in Table 4-17. All reductions are promulgated by the present day, and therefore these
reductions are the same for all MATS future year scenarios.

4.2.13.3     RICE NESHAP (ptnonipm and nonpt)
There are three rulemakings for National Emission Standards for Hazardous Air Pollutants (NESHAP) for
Reciprocating Internal Combustion Engines (RICE).  These rules reduce HAPs from existing and new RICE
sources. In order to meet the standards, existing sources with certain types of engines will need to install
controls.  In addition to reducing HAPs, these controls also reduce CAPs, specifically, CO, NOx, VOC, PM,
and SO2.  In 2014 and beyond, compliance dates have passed for all three rules; thus all three rules are
included in the 2017 reference case emissions projection.

The rules can be found at http://www.epa.gov/ttn/atw/rice/ricepg.html and are listed below:

   •   National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion
       Engines; Final Rule (69 FR 33473) published 06/15/04

   •   National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion
       Engines; Final Rule (FR 9648 ) published 03/03/10

   •   National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion
       Engines; Final Rule (75 FR 51570) published 08/20/2010
                                                52

-------
The difference among these three rules is that they focus on different types of engines, different facility types
(major for HAPs, versus area for HAPs) and different engine sizes based on horsepower (HP).  In addition,
they have different compliance dates.  We project CAPs from the 2005 NEI RICE sources, based on the
requirements of the rule for existing sources only because the inventory includes only existing sources and
the current projection approach does not estimate emissions from new sources.

A complete discussion on the methodology to estimate RICE controls is provided in Appendix F in the
Proposed MATS Rule TSD:
http://www.epa.gov/ttn/chief/emch/toxics/proposed_toxics_rule_appendices.pdf. Impacts of the RICE
controls on stationary non-EGU emissions (nonpt and ptnonipm sectors), excluding WRAP, Texas, and
Oklahoma oil and gas emissions (see Section 4.2.7) are provided in Table 4-18. These reductions are
promulgated before year 2017, and therefore these reductions are the same for all MATS future year
scenarios.

4.2.13.4      Fuel sulfur rules (ptnonipm and nonpt)
Fuel sulfur rules that were signed (enforceable) at the time of the emissions processing are limited to Maine,
New Jersey and New York.  Several other states have fuel sulfur rules that were in development but not
finalized prior to the final CSAPR and proposed MATS emissions processing:
http://www.ilta.org/LegislativeandRegulatoiYMVNRLM/NEUSASulfur%20Rules  09.2010.pdf.

The fuel sulfur content for all home heating oil SCCs in 2005 is assumed to by 3000 part per million (ppm).
Effective July 1, 2012, New York requires all heating oil sold in New York to contain no more than 15ppm
of sulfur, thus reducing SC>2 emissions by 99.5% for post-2012 projections. These New York sulfur content
reductions are further discussed here:
http ://switchboard.nrdc. org/blogs/rkassel/governor_paterson_signs_new_la. html.

The New Jersey year 2017 standard of 15ppm (assuming SOOppm baseline for Kerosene) sulfur content
yields a 96.25% SC>2 emissions reduction for kerosene (fuel #1). The New Jersey sulfur  content reductions
are discussed here: http://njtoday.net/2010/09/01/nj-adopts-rule-limiting-sulfur-content-in-fuel-oil/.

For MATS year 2017 projections, the Maine fuel sulfur rule, effective in year 2016, reduces sulfur to50 ppm
from 3,000 ppm in 2005, resulting in a 98.3% reduction for the 2017 scenario. The impact of these fuel
sulfur content reductions on 862 is shown in Table 4-19. These year-specific reductions are the same for all
MATS scenarios:  low-ethanol, reference and control.

4.2.14       Oil and gas projections in TX, OK, and non-California WRAP states
      (nonpt)
For the 2005v4.2 platform, we incorporated updated 2005 oil and gas emissions from Texas and Oklahoma.
For Texas oil and gas production, we used year 2017 estimates from the Texas Commission of
Environmental Quality (TCEQ) and used them as described in:
http://www.tceq.state.tx.us/assets/public/implementation/air/am/contracts/reports/ei/5820783985FY0901-
20090715-ergi-Drilling  Rig_EI.pdf.

We also received 2008 data for Oklahoma that we used as the best available data to represent 2017. We
utilized the latest available future year, year 2018, Phase II WRAP oil and gas emissions data for the non-
California Western Regional Air Partnership (WRAP) states to represent 2017.  RICE NESHAP reductions,
discussed earlier in this section, which are effective by year 2014, were applied to the year 2008 Oklahoma
oil and gas inventory but not applied to the 2017 TCEQ oil and gas estimates or 2018 WRAP Phase II oil and
gas inventory.

For Oklahoma, we applied CO, NOx, SO2 and VOC emissions reductions from the RICE NESHAP, which
we assumed has some applicability to this industry (see Appendix F in the Proposed Toxics Rule TSD:
http://www.epa.gov/ttn/chief/emch/toxics/proposed_toxics_rule_appendices.pdf).  All these year-specific oil
and gas projection estimates are the same for all MATS scenarios:  low-ethanol, reference and control. Table
4-20 shows the 2005 and 2017 NOx and SO2 emissions including RICE reductions for Oklahoma.

4.3  Onroad mobile source projections (onroad)
The same version of MOVES and SMOKE-MOVES Integration Tool was used to create all MATS onroad
emission scenarios. Section 2.2 describes these components in support of year 2005 processing. This
section will only address the differences related to creating and processing year 2017 reference case
emissions.  Speciation changes  for all scenarios are discussed in Section 3.

configurations (Section 2.2.4) were previously discussed and were the same for all MATS scenarios.
However, year-specific MOVES inputs were obtained for fuels and California LEV standards, and SMOKE
inputs of VMT and vehicle populations were year-specific and are described below.

For the 2017 VMT inventory, MOVES2010a was run with default inputs to generate total national VMT by
SCC.  But, because MOVES uses a static (1999) default allocation of VMT to county, MOVES was not used
for these allocations. Instead, the 2017 county VMT was created by interpolating between the NCD VMT
values for 2015 and those for 2020 and computing the NCD fraction for each county, then multiplying these
fractions by the MOVES VMT.  The VMT was also adjusted to account for increased onroad transportation
of ethanol fuels and the resulting increase in travel by large tanker trucks.

Vehicle populations by county and SCC were developed similarly to the VMT, using MOVES to generate
national totals for each year and using the NCD to allocate to county. However, the NCD does not include
population estimates, so we used MOVES to generate the 2005 national population and we assumed that, for
each calendar year (2005 and 2017) and for each SCC, the allocation of national vehicle population to
county was proportional to the allocation of VMT (summed across road types).

The MOVES 2017 emissions used for MATS reflect onroad mobile control programs including the Light-
Duty Vehicle Tier 2 Rule and the Mobile Source Air Toxics (MSAT2) final rule.

4.3.1  California LEV
The list of States which have implemented programs to require the sale of vehicles in their state certified for
sale in California began with the information stored in the modeling inputs used for the 2008 National
Emission Inventory (NET) stored in the National Mobile Inventory Model (NMIM) County database.  This
information was reviewed and updated by states during the process of developing the national inventory for
calendar year 2008. This information was supplemented with information from a "Dear Manufacturer"
letter, "Sales of California-certified 2008-2010 Model Year Vehicles (Cross-Border Sales Policy)" (October
29,2007) produced by the Compliance and Innovative Strategies Division of the US Environmental
Protection Agency which describes the areas that have recently implemented  a California standards program.
This information was used to generate emission rate table inputs for the MOVES model for each of these
areas using the guidance provided in the document, "Instructions for Using LEV and NLEV Inputs for
MOVES" (EPA-420-B-10-003, January 2010) provided to States with the MOVES model. For calendar year
2017, areas that had implemented California standards would still have these  programs in place in calendar
year 2017. More information on the states that have implemented California  LEV standards can be found at:
http://www.dieselnet.com/standards/us/tfcal.

4.4 Nonroad mobile source projections (nonroad, alm_no_c3,  seca_c3)
The components of the nonroad mobile sectors are discussed in Section 2.3. Nonroad mobile emissions
reductions for MATS include year-specific regulations affecting locomotives, various nonroad engines
including diesel engines and various marine engine types, fuel  sulfur content, and evaporative emissions.
This section discusses the changes due to the NONROAD/NMIM system (nonroad sector) and additional
C1/C2 CMV and locomotive emissions from volume increases resulting from incorporation of larger
amounts in renewable fuels  in the 2017 reference case.

4.4.1  Emissions generated with the NONROAD model (nonroad)
As discussed in Section 2.3.1, most nonroad emissions are were estimated using the EPA's NONROAD
model, as run by the EPA's  consolidated modeling system known as the National Mobile Inventory Model
(NMIM). NONROAD is EPA's model for calculating emissions from nonroad equipment, except for
aircraft, locomotives, and commercial marine vessels. Like the onroad emissions, the NONROAD/NMIM

                                               55

-------
system provides nonroad emissions for VOC by three emission modes: exhaust, evaporative and refueling.
Unlike the onroad sector, nonroad refueling emissions for nonroad sources are not included in the nonpoint
(nonpt) sector and so are retained in this sector.

The same temperatures and representative counties were used for all NONROAD model-generated MATS
scenarios. For 2017, El0 and El5 are available in every county, but nonroad equipment is assumed to burn
only E10. To generate the  NMEVI fuels, the E10 fuel was copied from MOVES to NMIM, and the E10
oxygenate was assigned a market share of 1.  Highway diesel fuel sulfur levels are copied directly from
MOVES to NMIM.  Nonroad diesel fuel sulfur levels are retained from NMIM.

Section 2.3.1.3 provides a cross-walk of the nonroad mobile NMIM emission scenarios used in MATS; as
previously discussed, the only difference between these scenarios are the increases in activity (based on
NONROAD model default growth estimates of future-year equipment population) and changes in fuels and
engines that reflect implementation of national regulations and local control programs that impact each year
differently due to engine turnover. For year 2017, EPA assumed that nonroad equipment would use only
E10. Although the NONROAD Model estimates changes in VOC production from E15, NMIM calculates
toxics as if the fuel were E10. Emission estimates for ethanol come from speciation of VOC in the SMOKE
model. These ethanol adjustments for nonroad engines running on El5 came from the EPAct Phase 1 data.

We have not included voluntary programs in our projections such as programs encouraging either no
refueling or evening refueling on Ozone Action Days and diesel retrofit programs. The national regulations
incorporated in all MATS future year scenarios are those promulgated prior to December 2009, and
beginning about 1990.  Recent rules include:
   •   "Clean Air Nonroad Diesel Final Rule - Tier 4": (http://www.epa.gov/nonroaddiesel/2004fr.htm ),
       published June 29, 2004, and,

   •   Control of Emissions  from Nonroad Large Spark-Ignition Engines, and Recreational Engines (Marine
       and Land-Based), November 8, 2002 ("Pentathalon Rule").

   •   OTAQ' s Locomotive Marine Rule, March 2008:
       (http ://www. epa. gov/otaq/regs/nonroad/420f08004 .htm)

   •   OTAQ's Small Engine Spark Ignition ("Bond") Rule, November 2008:
       (http ://www. epa. gov/otaq/equip-ld. htm)

All future year nonroad emissions used NMIM data that are based on AEO2009 fuels  and the same NMIM
county database NCD20101201Tier3. We converted emissions from monthly totals to monthly average-day
values based the on number of days in each month. Only criteria and select HAPs (benzene, acetaldehyde,
butadiene, acrolein, and formaldehyde) were retained when creating SMOKE one record per line (ORL)
files.

4.4.2  Locomotives and Class 1 & 2 commercial marine vessels (alm_no_c3)

 Aircraft emissions reside in the nonEGU point inventory (ptnonipm), and the projection factors used to create year 2017
  create year 2017 estimates, are discussed in Section 4.2.  The remaining 2005 NEI emissions for locomotives and Class 1
 and Class 1 and Class 2 commercial marine vessel (C1/C2 CMV) use year-specific projection estimates. Base future year
Base future year locomotive and C1/C2 CMV emissions were calculated using projection factors that were computed based
   computed based on national, annual summaries of emissions in 2002 and 2017. Some additional emissions were then
were then factored in due to changes in fuels. These national summaries were used to create national by-pollutant, by-SCC
  pollutant, by-SCC projection factors; these factors include final locomotive-marine controls and are provided in Table
 in Table 4-21. Modest additive Class I railroad and C1/C2 CMV emissions that account for RFS2 volume increases in

the MATS reference scenario were then added into the reference case due to the volume differences in corn, cellulosic and
              imported ethanol and cellulosic diesel fuels.  These additional emissions are summarized in

The future-year locomotive emissions account for increased fuel consumption based on Energy Information
Administration (EIA) fuel consumption projections for freight rail, and emissions reductions resulting from
emissions standards from the Final Locomotive-Marine rule (EPA, 2009). This rule lowered diesel sulfur
content and tightened emission standards for existing and new locomotives and marine diesel emissions to
lower future-year PM, 862, and NOx, and is documented at:
http://www.epa.gov/otaq/regs/nonroad/420f08004.htm.  Voluntary retrofits under the National Clean Diesel
Campaign (http://www.epa.gov/otaq/diesel/index.htm) are not included in our projections.

We applied HAP factors for VOC HAPs by using the VOC projection factors to obtain  1,3-butadiene,
acetaldehyde, acrolein, benzene, and formaldehyde.

Class 1 and 2 CMV gasoline emissions (SCC = 2280004000) were not changed for future-year processing.
C1/C2 diesel emissions (SCC = 2280002100 and 2280002200) were projected based on the Final
Locomotive Marine rule national-level factors provided in Table 4-21. Similar to locomotives, VOC HAPs
were projected based on the VOC factor.

Delaware provided updated future-year NOx, SO2, and PM emission estimates for C1/C2 CMV as part of the
Transport Rule comments.  These updated emissions were applied to the 2017 inventory and override the
C1/C2 projection factors in Table 4-21.

4.4.3 Class 3 commercial marine vessels (seca_c3)
The seca_c3 sector emissions data were provided by OTAQ in an  ASCII raster format used since the SO2
Emissions Control Area-International Marine Organization (ECA-IMO) project began in 2005. The (S)ECA
Category 3 (C3) commercial marine vessel 2002 base-case emissions were projected to year 2005 for the
2005 base case and to 2017, which includes ECA-IMO controls. An overview of the ECA-IMO project and
future-year goals for reduction of NOx, SO2, and PM C3 emissions can be found at:
http ://www. epa. gov/oms/regs/nonroad/marine/ci/420f09015 .htm

The resulting coordinated strategy, including emission standards under the Clean Air Act for new marine
diesel engines with per-cylinder displacement at or above 30 liters, and the establishment of Emission
Control Areas is at: http://www.epa.gov/oms/oceanvessels.htm
                                               59

-------
These projection factors vary depending on geographic region and pollutant; where VOC HAPs are assigned
the same growth rates as VOC. The projection factors used to create the 2017 seca_c3 sector emissions are
provided in Table 4-23. Note that these factors are relative to 2002. Factors relative to 2005 can be
computed from the 2002-2005 factors.

The geographic regions are described in the EGA Proposal technical support document:
http://www.epa.gov/oms/regs/nonroad/marine/ci/420r09007-chap2.pdf These regions extend up to 200
nautical miles offshore, though less at international boundaries.  North and South Pacific regions are divided
by the Oregon-Washington border, and East Coast and Gulf Coast regions are divided east-west by roughly
the upper Florida Keys just southwest of Miami.

The factors to compute HAP emission are based  on emissions ratios discussed in the 2005v4 documentation
(ftp://ftp.epa.gov/EmisInventory/2005v4/2005_emissions_tsd_07jul2010.pdf). As with the 2005 base case,
this sector uses CAP-HAP VOC integration.

4.5 Canada, Mexico, and offshore sources (othar, othon, and othpt)
Emissions for Canada, Mexico, and offshore sources were not projected to future years, and are therefore the
same as those used in the 2005 base case for all MATS scenarios. Therefore, the Mexico emissions are
based on year 1999, offshore oil is based on year 2005, and Canada is based on year 2006. For both Mexico
and Canada, their responsible agencies did not provide future-year emissions that were consistent with the
base year emissions.

5  MATS Control Case
For the future year control case (i.e., policy case) air quality modeling, the emissions for all sectors were
unchanged from the base case modeling except for those from EGUs.  The IPM model was used to prepare
the future year policy case for EGU emissions. The air quality modeling for MATS relied on EGU emission
projections from an interim IPM platform based on the Cross-state Air Pollution Rule version
4.10_FTransport, and was subsequently updated during the rulemaking process. The updates made include:
updated assumptions regarding the removal of HC1 by alkaline fly ash in subbituminous and lignite coals; an
update to the fuel-based mercury emission factor for petroleum coke, which was corrected based on re-
examination of the 1999 ICR data; updated capital cost for new nuclear capacity and nuclear life extension
costs; corrected variable operating and maintenance cost (VOM) for ACT retrofits; adjusted coal rank
availability for some units, consistent with EIA From 923  (2008);  updated  state rules in Washington and
Colorado; and numerous unit-level revisions based on comments received through the notice and comment
process. Additional details on the version of IPM used to  develop the control case are available in Chapter 3.

The changes in EGU 862, and PM2.5 emissions as a result of the policy case for the lower 48 states are
summarized in Table 5-1.  Table 5-2 shows the CAP emissions for the modeled MATS control case by State.
State-specific difference summaries of EGU SC>2 and PM2.5 for the sum of the lower 48 states are shown in
Table 5-3 and Table 5-4 respectively.

The ancillary data files used for the MATS cases are shown in Table A-l. The Input name column gives a brief designator for the dataset.  The
Environment Variable column gives the name of the environment variable that is used by SMOKE to specify the input.  The Sector column
specifies the modeling sector for the dataset. The remaining columns show the data set name and version used in the 2005 base case and 2017
reference case.

To match the Datasets and Versions listed in this table to actual data files, combine the Dataset name and the version number in the following
pattern: __.txt, where  is the last date of change for that version and will have a unique value
for the combination of Dataset Name and Version number.

Table A-2 shows the parameters used for the MATS modeling cases. The columns are the same as in Table A-l except that the Program is not
shown. Many of the parameters apply to all programs, or all programs for the specified processing sector. The values for the control case are
not shown, but they are the same as those used for the 2017 reference case.

                           Table A-l.  List of ancillary data sets associated with the MATS modeling cases.

                  Inventory Data Files Used for Each MATS Modeling Case - SMOKE Input Inventory Datasets

The emissions inventory data files used for the MATS cases are shown in Table B-l. The Input name column gives a brief designator for the
inventory. The Sector column specifies the modeling sector for the inventory. The remaining columns show the data set name and version
used in the 2005 base case and 2017 reference cases. The datasets used for the 2017 control case are identical to the 2017 reference case,
except for the following replacements:

   •   Inventory ptipm CAP used PTINV_EPA41 OFINAL_BC_226_summer_2015_01SEP2011_ORL [vO],
   •   Inventory ptipm daily data (CEM sources) used ptday_ptipm_cem_2017ct_ref_mats_05b [vO], and
   •   Inventory ptipm daily data (nonCEM sources) used ptday_ptipm_noncem_2017ct_ref_mats_05b [vO].

To match the Datasets and Versions listed in this table to actual data files, combine the Dataset name and the version number in the following
pattern: __.txt, where  is the last date of change for that version and will have a unique value
for the combination of Dataset Name and Version number.

                           Table B-l.  List of inventory data sets associated with the MATS modeling cases.
