## 1 **Introduction to the**  **M odeling**  **P latform**  This Technical Support Document (TSD) describes the development of the emissions inventories used as inputs to the air quality

modeling that th e 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 s ys tem (http://www.smoke

- model.org/index.cfm) v ersion 2. 7 processed into the form required b y 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. A s part of the anal ys is for this rulemaking, the modeling s ys tem was used to calculate daily and annual PM 2.5 concentrations, 8

- hr maximum ozone and visibility impairment. Model predictions of PM 2.5 and ozone are used in a relative sense to estimate scenari o - specific, future

- year design values of PM 2.5 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 ye ar 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 ye ar emissions and 2005 meteorology for modeling ozone and PM 2.5 with CMAQ. In support of this rule, EPA modeled the air quality in the Eastern and the Western United States using two separate model r uns, 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 informati on 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 P ollution 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 Independence2 and Security Act of 2007 (EI SA) and the Energy Policy Act of 2005 (EPAct) on mobile source fuels. **Table 1**  **- 1**  **.** Li st of cases run in support of the MATS air quality modeling for the RIA **Case Name Internal EPA**

. 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 amon g each of the cases run . In Section 4 , we describe the 20 17 Reference (i.e., future ye ar 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**  **I nv** **entories and Their P**  **reparation** 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, w e identify the differences between the data used for the MATS 2005v4.3 platform and that used for the 2005v4.2 platform. Section 2.1 provide s 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 2.6 5 provide differences for the nonpoint and nonpoint (area) inventories, respectivel y. 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#2005 ), also known as the CAP

- BAFM 2005

-based Version 4.2 P latform (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 contra st to wh at 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 (formerl y known as the “Transport Rule”)

. A base case approach uses3 average ye ar fires and EGU temporal profiles from three years of EGU data. We use a base case approach because we want to reduce ye ar- specific variability in some components of the inventory . For example, large fires vary

in location and day

of the ye ar 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 2005 v4.2 platform was used for the 2005 case, and also for both future

- year cases. The onl y significant data changes between the 2005 and the 2 017 future

- ye ar 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 (NEI) . Subsequent sub sections refer to these platform sectors to identify the emissions differences between the 2005 v4 .2 platform and the MATS 2005v4.3

-based platform.

+ Some data included in modeling sector has been revised beyond what is included in the 2005 NEI v 1 or v2. 

### 2.1 **Custom configuration for emissions modeling for MATS**  Unlike the 2005v4.2 platform, the configuration for MATS modeling included additional hazardous air pollutants (HAP s) 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 2005 v4 .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

- ye ar cases as compared to 2005. Section 3 provides a detailed account of these differences. The future

- ye ar ancillary data were largel y 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 SMO KE to MOVES processing can otherwise be found at the 2005

-based platform website (http://www.epa.gov/ttn/chief/emch/index.html#2005 ).5

modes, the MP “lite” version of CMAQ , and, to accept inventory Ethanol (ETOH). The 2005v4.2 platform data file is confi gured to support only the non - MP version. 

### 2.2 **Onroad m**  **obile s**  **ources (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 Tool s 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 repeatedl y 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 temporall y 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. Italso 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 20 05 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 thermody namic equations which govern atmospheric motions. The Meteorology

- Chemistry Interface Processor (MCIP) version 3.4 was used as the software for maintaining dy namic consistency

between the meteorological model and chemistry mechanisms

. The hourl y gridded meteorological data was post

processed b y m et4moves 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.

- 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 (NE I). This inventory

covers the 50 United States (U.S.), Washington DC, Puerto Rico and U.S. Virgin Islands. The NE I was created b y the EPA's Emissi on Inventory and Analysis Group (EIA G) 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 s ys tem 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 NE I "Documentation f or 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 ( TranS ys tems , Contract No. EP

- 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 availa

ble 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 c onsistent 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 specificall y 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 c**  **ounties** Although EPA compil es 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 perfor med 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 there fore would have similar emission rates. Then, we explicitly model onl y 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.8 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 us e 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 independentl y of fleet mix, speeds and temperature. This greatl y increases the number of counties that can be in each grouping, since temperature is a factor that varies among the counties 1

. For this anal ys is, we grouped counties with similar fuel, emission standards, altitude , and inspection and maintenance ( I/M ) program s. 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 al l 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 b y EPA, the contractor generated appropriate estimates for v ehicle 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

- 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 conceptuall y simple. In the tree algorithm, all counties are assigned to various categories. Then by grouping counties within the same categories, yo u 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 (1a, 1b and 1c). 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 fuel supp ly 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

Since the emission rates in these states will be different than in neighboring states, they must be modeled separatel y. Also, because the implementation of Cali fornia 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. **Table 2**  **- 6**

- 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 separatel y 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 set11 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

- PADD groupings and each sub

- group is treated as a separate PADD (1a, 1b and 1c). Each state belongs to a PADD and all counties in any state are within the same PADD. Fuel Parameters Average gasoline fuel properties for January and July 2005, including RVP, sulfur level, ethanol fraction and percent benzene. Emission Standards. Some states have adopted California highway vehicle emission standards or plan to adopt th em. Since implementation of the standards varies, each state with California standards is treated separately

. Inspection/Maintenance Programs 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 separatel y and have a different program design. Altitude Counties are either high or low altitude based on the criteria set forth b y EPA certific ation procedures (4,000 feet above sea level). Using these criteria, a set of 106 counties were selected to represent the nation. Of these, onl y 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 mo nths = 37,692 county

- months. The MOVES runs for each representative county and fuel month were performed independentl y of one another on different computer processors each accessing a M yS QL database specific to that run. 

### 2.2.3 **SMOKE -**  **MOVES i**  **nputs** Both MOVES and SMOKE re quire 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 wheth er 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 emission s.12 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 dail y or monthly mode for producing SMOKE input. In monthly mode, the temperature range is determined b y 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 b y 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. Ty pically, th e 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 b y MOVES, SMOKE requires county VMT, population, and average speed b y road typ e 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. Accordingl y, for the 2005 base year, our estimates of VMT b y 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 typ e. 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 hourl y vehicle miles traveled (VMT) distribution found in the MOVES default database Hourly VMTFraction table, to calculate an average speed for each road typ e. This average speed b y road ty pe was provided to SMOKE for each county

. 

### 2.2.4 **Generating e**  **mission f** **actors 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 meteorol ogical 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 wa s the following : 1) OAQPS ran m et4 m oves 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 to13

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, met4m oves 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, (runspe c_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 run spec_generator script produc e d MOVES run - spec ifications that control how the MOVES run is configured, along zonemonthhour table s in CSV format . Specifications were generated for the three types of MOVES processes: rate

-perdistance (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 b y 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 b y 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 My SQL tables into the emission factor tables in CSV format that is readable by the SMOKE moves mrg program. The postprocessor also performed additional calculations to support SMOKE processing of CMAQ ready model emissions: speciating HONO from NO and NO 2 , speciating the AE5 PM species (PE C, 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, hourl y, speciated emissions for CMAQ. See the next section for details. 

### 2.2.5 **Running SMOKE for o**  **nroad mobile**  Running SMOKE using emission factors (EF) from MO VES required the development of a new set of functionality . The central SMOKE program that performs this new anal ys is 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.14 The emissions process RPD is for modeling the on

- network emissions. This includes the following modes: vehicle exhaust, evaporation, permeation, break we ar, and tire wear. For RPD, the activity data is monthly VMT, monthly

speed (SPEED), and hourl y 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 hourl y 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 hourl y 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 u ses 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 b y 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 m**  **obile s**  **ources (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 u pstream 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 g**  **enerated with the NONR**  **OA D**  **m o**  **del (**  **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 NO x showed a 0.8% increase, VOC showed a 1% increase, and PM 2.5 showed a 3% increase).15 locomotives, and commercial marine vessels

. The NONROAD Model and extensive documentation can be found at http://www.epa.gov/otaq/nonrdmdl.htm

. NMIM 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 b y the user, and collects the results in an output database

. In formation 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 NM IM 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 20 08 National Emission Inventory process : http://www.epa.gov/ttn/chief/net/2008inventory .html

. In particular, for this analysis, we made updates to the underl ying fue l supply for the post EIS A/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 county monthhour table that contained 2005 meteorology was copied into the standard county monthhour table. The use of the county monthhour table for meteorology was selecte d by

the RunSpec setting useYearl yW eatherDataSelected="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 226000 1020), 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 co ncentrations were observed in rural areas during winter due to snowmobile emissions , available at: http://www.epa.gov/otaq/renewablefuels/420r10006.pdf

. The increases were based on data from only three engines, which showed unusually high1,3

-butadiene emissions with 10% ethanol (Eth oxygenate) . Other data suggests that this increase is highl y 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% b y volume or Ethyl Tertiary Butyl Ether (ETBE) is greater than or equal to 5% b y volume. MTBE gas is used where the fuel contains MTBE which is greater than or equal to 12% by

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 SMOKE16 **2.3.1.1 Representing**  **c ounties for**  **NONROA D**  “Representin g counties” is a way of saving NM IM run time by grouping together similar counties and generating emission factors by running the NONROAD Model for onl y one of those counties and then using those emission factors for all the counties in the group. For thi s anal ys is, 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 NM IM 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

.

**Table 2**  **- 9**  **.** Criteria for grouping representative c ounties for nonroad mobile anal ys is **Characteristic Grouping Criteria**  Petroleum Administration for Defense District (PADD) All counties in a group must be in the same PADD. Gasoline parameters 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. Inspection/Maintenance Programs Counties with I/M programs were grouped with other counties with I/M programs in the same state. Altitude All counties in the group must be in the same altitude category (high or low). Temperatures Al l 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 ye ar values in the CountyY earMonthHour table of the NCD20100602 NMIM database. As shown in17 Table 2

- 10 , ten degree F ahrenheit (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

The same set of 293 county groups and representing counties was used for all years and scenarios. **2.3.1.2 Fuel inputs for NONROA**  **D r uns**  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 w ere 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 oxygen ates and California ethanol occur in onl y 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, th e 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**  **r uns**  Table 2

However, for 2017, EPA **Case Year**  **Run Name** Base 2005 Tier3Base2005Nr Reference 2017 Tier3Ref2017e10Nr19 assumed that nonroad equipment would use only E10.

### 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 onl y NEIpoint 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

.20 After removing offshore oil platforms (othpt sector), we created two platform sectors from the remaining 2005v2 NEI point sources for input into SMOKE: th e EGU sector

– also called the Integrated Planning Model (IPM) sector (i.e., ptipm) and the non

- EGU sector

– also called the non

- IP M sector (i.e., ptnonipm). This split facilitates the use of different SMOKE temporal processing and future

- ye ar projection techniques for each of these sectors. The inventory pollutants processed through SMOKE for both ptipm and ptnonipm sectors were: CO, NO X , VOC, SO 2 , NH 3 , PM 10 , and PM 2.5 and the following HAPs: HCl (pollutant code = 7647010 ), and CL2 (code = 7782505 ). W e 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 dail y 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 ye ar 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

-b ased 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 onl y 4 billion gallons of ethanol, essentially a scenario without a future ye ar RFS2 mandate (or MATS ). All ethanol plants were assigned or corrected (after quality assurance anal ys es) coordinates based on anal ys is 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 ty p e (e.g., coal, natural gas) . Finall y, because benzene, acetaldehyde and formaldehyde (BAF) emissions were directl y 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

### 2.5 **2005 n onpoint**  **s ources**  **(afdust, ag, avefire, nonpt)** The year 2005 area- source fugitive dust (afdust), agricultural animal and fertilizer NH 3 (ag), and average (ty pical)

- ye ar 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 **P ortable 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 ye ar 2017 ref

erence 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 r efueling**  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 f or 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 S ection 2. 2 for onroad counties, w e selected representing counties b y 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 of ten degrees F were created for the minimum and max imum temperatures for each month using the temperatures from the 2005 calendar year values in the County YearMonthHour table of the NM IMCounty Database (NCD) NCD20100602 NMIM database. All counties in each group had min and max temperatures for all twelve months in the same temperature bins. Once counties were groupe d, 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 onl y the repres enting counties using the county

- specific on

- road data, such as vehicle miles travelled, fleet age distribution, speed distribution, and meteorology , available fro m 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.22 

### 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 ye ars.

## 3 **VOC S**  **peciation C**  **hanges that Represent Fuel C**  **hanges** 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 v arious cases

. A maj or 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, formaldehyd e 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 details25 ftp://ftp.epa.gov/EmisInventory /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 8751 E. 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

- ye ar 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 case s. Additional updates include headspace vapor speciation utilizes a combination of the E10 headspace vapor profile and E0 headspace vapor profile as opposed to using solel y E0 for 2005 5 , and a new Heavy Duty Diesel vehicle exhaust mode profile for pre

200 7 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 chang es 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 sources 6

. 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 fuel 7 . Mapping of fuel dis tribution 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/420r10005.pdf ). Table 3

- 1 summarizes the different profiles utilized for the fuel

- related sources in each of the sectors for 2005 and the future ye ar 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 mo de (e.g. exhaust, evaporative, permeation). SMOKE calculates a resultant profile by calculating the fraction of each profile by month, county, and mo de. 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 E0. 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.26 **Table 3**  **- 1**  **.** Summary

## 4 **20 17**  **Reference Case**  The 2017 reference case represents the future, including the implementation of emissions impacts of the fuel volumes mandated b y the 2005 EPAct and 2007 EI SA 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 g allons 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 source s, onroad mobile including refueling sources, OTAQ

- generated emissions were provided to reflect the reference case fuels. The 20 17 reference case use s 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 20 17 reference case for MATS : 1) 20 17 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 ye ar - specific; so while the methodology is the same as CSAPR, the future year emissions estimates differ (e.g., o il and gas in a couple states, residential wood combustion). 3) Onroad refueling uses ye ar 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 emission s 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 De cember 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 PM 2.5 NAAQS annual standard, 2006 PM NAAQS (24

- hour) standard, and the 1997 ozone NAAQS are generall y not included in the future base

case projections for most states. One exception are some NO X 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 the29 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 e stimates from IPM, version 4.10.
 Non
- IP M 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 (TAF) 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 NH 3 emissions fro m 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 stove s. 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 wa s discussed in Section 3
.  Nonroad mobile sector (nonroad): Same version of the NONRO AD2008a , including same set of 293 county groups and representing counties as the 2005 base case . Future
- ye ar equipment population estimates and control programs (final locomotive

- marine and small spark ignition) to 2017 are included

. The onl y differences between the MATS future case runs are the fuels used, specificall y, 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
- ye ar 2005 emissions grown and controlled to 20 17 , incorporating CSAPR Proposal comments and controls based on Emissions Control Area (ECA) and International Marine Organization (IMO) global NO X and SO 2 controls.
 Onroad mobile sector uses a version M OVES developed for the Tier 3 Proposal that incorporates new car and light truck greenhouse gas emissions standards (LDGHG) affecting model ye ars 2012 and later (published May

7, 2010). These emissions also include RFS2 fuels. VOC speciation uses different future

- ye ar 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.30

 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 p oint (othpt): No growth or control.
 Biogenic: 2005 emissions used for all future

- ye ar scenarios.31 Table 4

- 1 summarizes the control strategies and growth assumptions by source type that were used to create the 20 17 reference

- case emissions from the 2005v4.2 base

- case inventories. These future year base case proj ections 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 (datas ets) 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 b y 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 categorie s are provided in parentheses.32

### 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, dy namic, deterministic linear programming model of the U.S. electric power sector. V ersion 4.1 0 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 c ase, also known as the future year baseline, emissions do not reflect the final Mercury and Air Toxics (MATS) r ule , but the control case emissions do reflect the r ule. 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 (NODA) publ ished 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 IC R and on comments from the IPM NODA. 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 s tate
- 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 HCl found in the coal was emitted into the atmosphere. However, in the final IPM results for the rule, neutralization of 75% of the available HCl 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 B oiler 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 emi ssions were very similar to the year 2015 emissions output from the same IPM modeling case. Directl y emitted PM emissions (i.e., PM 2.5 and PM 10 ) from the EGU sector are computed via a post processing routine which applies emission factors to the IPM
- estim ated 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.36 

### 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 directl y from OTAQ. In estimating future

- ye ar 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 f

or 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 respons es 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 recentl y compiled for 2005 and a ye ar 2017 without the RFS2 mandate (not separatel y 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

### 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 ye ar (Bgal) of biodiesel fuel productio n 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 nee d 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 were38 modeled as point sources with Google Earth and web searching validating facility coordinates and correcting state

### 4.2.3 **Portable fuel containers (nonpt)** OTAQ provided ye ar 2017 PFC emis sions that include estimated Rei d 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 per

meation 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
. **Table 4**  **- 5**  **.** PFC emissions for 2017 **Pollutant Tons**  VOC 123,186 Benzene 1,368 Ethanol 11,565 

### 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 conceptuall y to that for building th e 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.41 Table 4

- 6 provides the ye ar 2017 cellulosic plant emissions estimates.42 **Table 4**  **- 6**  **.** 2017 c ellulosic plant emissions **Pollutant Tons**  Acrolein 21 Formaldehyd e 58 Benzene 27 Acetaldehyd e 786 CO 42,839 Ethanol 1,875 NH 3 0.5 NO X 64,062 PM 10 7,533 PM 2.5 3,796 SO 2 4,973 VOC 5,336 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: Ind ustrial 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 entirel y evap orative and therefore limited to VOC and are summarized in Table 4

- 7 . The leading descriptions are “Industrial Processes; Food and Agriculture; Ethanol Production” f or each SCC. **Table 4**  **- 7**  **.** VOC losses (Emissions) due to ethanol transport and distribution **SCC Description**  **Tons** 30205031 Denatured Ethanol Storage Working Loss 27,763 30205052 Ethanol Loadout to Truck 19,069 30205053 Ethanol Loadout to Railcar 9,610 

### 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 anal ys is, 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 ag e 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 emissi ons is provided in43 Table 4

### 4.2.7 **Refinery**

**adjustments (ptnonipm)** Refinery emissions were adjusted for changes in fuels due to the RFS2 mandate. These adjustments were provided b y OTAQ and impact processes such as process heaters, catal ytic cracking units, blowdo wn systems, wastewater treatment, condensers, cooling towers, flares and fugitive emissions. The impact of the RFS2

-based reductio ns is shown in Table 4

- 9
.

**Table 4**  **- 9**  **.** Impact of refinery adjustments on 2017 emissions **Pollutant Reductions**  **(tons)** CO 12,674 NO X 20,183 PM 10 4,367 PM 2.5 2,525 SO 2 13,846 VOC 3,693 

### 4.2.8 **Ethanol transport gasoline and blends (ptnonipm, nonpt)** Emission s 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 b y 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 (NH 3 only), agricultural tilling, unloading and livestock dust (PM only) and fertilizer production mixing and blending, pestic ide 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 emission s for upstream agricultural sources.

**Table 4**  **- 10**  **.** Upstream agricultural emission increases due to RFS2 fuels in 2017 **Pollutant Increases**  **(tons)** CO 302 NH 3 45,272 NO X 363 PM 10 42,934 PM 2.5 6,500 SO 2 69 VOC 1645 

### 4.2.10 **Livestock emissions growth (ag, afdust)** Growth in ammonia (NH 3 ) and dust (PM 10 and PM 2.5 ) emissions from livestock in the ag , afdust and ptnonipm sectors was based on projections of growth in animal population. Table 4

- 11 Table 4

- 11 provides the growth factors from the 2005 base

- case emissions to all MATS year 2017 s cenarios for animal categories applied to the ag , afdust , and ptnonipm secto rs 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 (USDA) 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 anal ysis of historical trends in th e 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 turkey s; therefore, we did not use these forecasts for estimating future

- ye ar 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 directl y 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: http://www.epa.gov/scram001/reports/Emissions%20TSD %20Vol2_Appendices_01

### 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 typ es 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 Anal ys is (EPA, 2006). The spe cific assumptions we made were:46

 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 Platfor m missions for PM 2.5 . 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 2002 v3 NEI. This approach results in an overall decrease of 1.056% per ye ar for this source category

. We discovered an interpolation error in the ye ar 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

### 4.2.12 **Ai rcraft growth (ptnonipm)**  These 2005 point

- source emissions are projected to future years by appl ying 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 (TAF) 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 ye ars up to 20 30 . We aggregated and applied this information at the national level b y summing the airport

- specific (U.S. airports o nly) ITN operations to47 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 ty pe b y dividing future

- year ITN b y 2005

- ye ar 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 TAF 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 emiss ions

. The same airc raft factors were used for each of the ye ar- specific scenarios: low

- ethanol, reference and control.

- 5 1.0229 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 NO X standard adopted b y the International Civil Aviation Organization’s (ICAO) Committee on Aviation Environmental Protection (CAEP) in February 2004, which is expected to reduce NO X 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

- ye ar emissions projections. 

### 4.2.13 **Stationary s**  **ource control programs, consent decrees & settlements, and plant closures (ptnonipm, nonpt)**  We applied emissions reduction factors to the 200 5 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 in48 Appendix D of the CSAPR TSD: ftp://ftp.epa.gov/EmisInventory /2005v4_2/transportrulefinal_eitsd_appendices_28jun2011.pdf

. Controls from the NO X SIP call were assumed to have been imp lemented 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 b y the NO X SIP call. The future

- ye ar 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

- ye ar 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 ye ars) were also included where information indicated that the plant was actually closed after the 2005 base ye ar and prior to CSAPR and MATS modeling that began in the spring of 201 1
. We also applied unit and p lant 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 201 7 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. **Table 4**  **- 15**  **.** Summary

 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 s ectors.
 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: http://www.epa.gov/ttn/chief/emch/toxics/proposed_toxics_rule_appendices.pdf

. The detailed data used are available at the website listed in Section 1.
 Refinery

consent decrees controls at the facility and SCC level (collected through internal coordination on refineries by the EPA).
 Fuel sulfur fuel limits were enforceable for Maine , New Jer sey and New York.49

 Criteria air pollutant (cap) reductions a cobenefit to RICE NESHAP controls , including SO 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 NO X 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.ny .gov/docs/air _pdf/NYMASIP7final.pdf

. See Section 3.2.6 in the CSAPR TSD: 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 limit s, 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 of 0.25. **4.2.13.1 R** **eductions from the Portland Ce ment NESHA**  **P (ptnonipm)**  As indicated in Table 4

- 1 , the Industrial Sectors Integrated Solutions (I SI S) model (EPA, 2010) was used to project the cement industry component of the ptnonipm emissions modeling sector to 20 13. There were no future ye ar 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 I SI S 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 IS IS

-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 I SI S

-based policy case predictions of emissions reductions and activity growth. The I SI S 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 PM 2.5 nonattainment areas. The I SI S 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.50 Table 4

- 1651 Table shows the magnitude of the ISIS

-based cement industry reductions in the future

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

. All reductions are promulgated b y the present day, and therefore these reductions are the same for all MATS future ye ar scenarios.

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, specificall y, CO, NO X , VOC, PM, and SO 2 . 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 08/20/201053 The difference among these three rules is that they focus on different types of engines, different facility typ es (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 onl y because the inventory includes only

existing sources and the current projection approach does not estimate emiss ions 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.g ov/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 ye ar 2017, and therefore these reductions are the same for all MATS future ye ar scenarios. **Table 4**  **- 18**  **.** National impact of RICE c ontrols on non - EGU p rojections **CO NO**  **X PM**  **10 PM**  **2.5 SO**  **2 VOC**  **Reductions** 116,434 111,749 1,595 1,368 21,957 14,669 **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/LegislativeandRegulatory /MVNRLM/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 SO 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 500ppm baseline for Kerosene ) sulfur content yi elds a 96.25% SO 2 emissions reduction for kero s ene (fuel #1). The New Jersey sulfur content reductions are discussed here: http://njtoday .net/2010/09/01/nj

. The impact of these fuel sulfur content reductions on SO 2 is shown in Table 4

California Western Regional Air Partnership (WRAP) states to represent 2017 . RICE NESHAP reductions , discussed earlier in this section , which are effective by ye ar 2014, were applied to the year 2008 Oklahoma oil and gas inventory

but not applied to the 20 17 TCEQ oil and gas estimates or 2018 WRAP Phase II oil and gas inventory

. For Oklahoma, we applied CO, NO X , SO 2 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_toxi cs_rule_appendices.pdf )

. All these ye ar- specific oil and gas projection estimates are the same for all MATS scenarios: low

- ethanol, reference and control. Table 4

### 4.3 **Onroad m obile**  **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. Inputs for temperatures (Section 2.2.1) , the representative counties and fuel months (Section 2.2.2), the overall parallel processing procedures (Section 2.2.3), speed data (Section 2.2.4 ), and SMOKE

- MOVES55 configurations ( Section 2.2.4) were previousl y 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 ye ar - specific and are describ ed 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 b y interpolating between the NCD VMT values for 2015 and those for 2020 and computing the NCD fraction for each county, then multiplying these fractions b y 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 b y 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 ye ar (2005 and 2017) and for each SCC, the allocation of national vehicle population to county w as proportional to the allocation of VMT (summed across road ty pes). The MOVES 2017 emissions used for MATS reflect onroad mobile control programs including the Li ght

Duty Vehicle Tier 2 Rule and the Mobile Source Air Toxics (MSAT2) final rule. 

### 4.3.1 **Californ ia 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

(NEI) stored in the National Mobile Inventory Model (NMIM) County

database. This information was reviewed and updated b y states during the process of developing the national inventory for calendar year 2008. This information was supplemented with information from a "De ar Manufacturer" letter, "Sales of California

- certified 2008

- 2010 Model Year Vehicles (Cross

- Border Sales Policy)" (October 29,2007) produced b y the Compliance and Innovative Strategies Division of the US Environmental Protection Agency

which describes the areas that have recentl y 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 ye ar 2017. More information on the states that have implemented California LEV standards can be found at: http://www.dieselnet.com/standards/us/#cal

### 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 ty p es, fuel sulfur content, and evaporative emissions. This section discusses the changes due to the NONROAD/NMIM s ys tem (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 NONROA D model (nonroad)**  As discussed in Section 2.3.1, most nonroad emissions are were estimated using the EPA’s NONROAD model, as run b y the EPA’s consolidated modeling s ys tem 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/ NMIM56 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, E10 and E15 are available in every county, but nonroad equipment is assumed to burn only E10. To generate the NMIM fuels, the E10 fuel was copied from MO VES 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

- ye ar equipment population) and changes in fuels and engines that reflect implementation of national regulations and local control programs that impact each year differentl y due to engine turnover

. For year 2017, EPA assumed that nonroad equipment would use only E10. Although the NONROAD Model estimates ch anges 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 E15 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 200 9 , 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 L arge 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.

### 4.4.3 **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 SO 2 Emissions Control Area

- International Marine Organization (ECA

- IM O ) 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 include s ECA

- IMO controls. An overview of the ECA

- IMO project and future

- ye ar goals for reduction of NO X , SO 2 , and PM C3 emissions can be found at: http://www.epa.gov/oms/regs/nonroad/marine/ci/420 f09015.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.htm60 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 ECA Proposal technical suppo rt 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 b y roughl y the upper Florida Keys just southwest of Miami. The factors to compute HAP emission are based on emissio ns 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 C AP

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

## 5 **MA TS Control Case**  For the future ye ar 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 ye ar 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 HCl by alkaline fl y ash in subbituminous and lignite coals; an update to the fue l

-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 ACI 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 SO 2 , and PM 2.5 emissions as a result of the policy case for the lower 48 states are summarized in Table 5

. Table 5

## APPENDIX **A Ancillary Datasets**  **and Parameters Used for Each MATS Modeling Case**  The ancillary

data files used for the MATS cases are shown in Table A

- 1. 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 ba se 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: <Dataset Name>_<Date>_<Version number>.txt, where <Date> is the last date of change for that version and will have a unique value for the combination of Dataset Name and Version numb er. Table A

- 2 shows the parameters used for the MATS modeling cases. The columns are the same as in Table A

- 1 except that the Program is not shown. Many

of the parameters appl y 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.

## APPENDIX **B Inventory Data F**  **iles 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

- 1. 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:

 Inv entory

ptipm CAP used PTINV_EPA410FINAL _BC_226_summer_2015_01SEP2011_ORL[v0] ,  Inventory

ptipm daily

data (CEM sources) used ptday _ptipm_cem_2017ct_ref_mats_05b [v0] , and  Inventory

ptipm daily

data (nonCEM sources) used ptday _ptipm_noncem_2017ct_ref_mats_05b [v0]

. 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: <Dataset Name>_<Date>_<Version number>.txt, where <Date> is the last date of change for that version and will have a unique value for the combination of Dataset Name and Version number
