### Re: Request to Parallel Process the Draft MOBILE6.2 to MOVES MVEB Replacement Update to the South BendElkhart Maintenance Area under the 1997 8-Hour Ozone Standard The Indiana Department of Environmental Management (IDEM) submits the enclosed MOBILE6.2 to Motor Vehicle Emissions Simulator (MOVES) Motor Vehicle Emissions Budget (MVEB) replacement update for the South Bend-Elkhart Maintenance Area under the 1997 8-hour ozone standard. The South Bend-Elkhart maintenance area includes St. Joseph and Elkhart counties. IDEM requests that the United States Environmental Protection Agency (U.S. EPA) parallel process this draft submittal for approval into Indiana's State Implementation Plan. IDEM is providing an opportunity for a public hearing on the MVEB replacement update to the South Bend-Elkhart maintenance area if a public hearing request is received by July 11, 2012. A hearing has been scheduled for July 18, 2012. If a request for a public hearing is not received by July 11, 2012, the hearing will be cancelled. The final submittal of the MVEB update for the South Bend-Elkhart maintenance area will document the public review process, including a detailed summary of and response to substantive comments. This MOBILE6.2 to MOVES MVEB replacement update incorporates onroad emission estimates and revised MVEBs using U
.S. EPA's recently adopted MOVES model. The onroad emission estimates were calculated using the MOVES-based emission factors and data extracted from the South Bend-Elkhart area's travel-demand model. MVEBs are being revised in anticipation of the mandatory use of the MOVES model in future transportation conformity determinations. Preliminary use of the new model indicates that emission estimates can be considerably different than similar RecycledPaper

### Ms. Hedman Page 2 calculations using MOBILE6.2, which was used to create the MVEBs in the original ozone maintenance plan. On road safety margins, established through the interagency consultation process, are included for nitrogen oxides (NOx) and volatile organic compounds (VOCs). These onroad safety margins are allocated to on road emission estimates in order to account for the wide array of assumptions that are factored into the calculation process. With the addition of on road safety margins applied to mobile sources, the South Bend-Elkhart maintenance area will continue to remain well below the overall safety margins for all sources. MVEBs are also constrained to ensure that total NOx and VOC emissions (i.e., all source categories) do not exceed attainment year emissions, to ensure continued maintenance of the 1997 8-hour ozone standard.

# Onroad Emissions MOBILE6.2 to MOVES Replacement Submittal

For the South Bend-Elkhart, Indiana Maintenance Area under the 1997 8-Hour Ozone Standard

DRAFT June 2012

### This page intentionally left blank

### Introduction On May 30,2006, the Indiana Department ofEnvironmental Management (IDEM) submitted a Request for Redesignation andMaintenance Planfor Ozone Attainment in the 8-Hour Ozone NonattainmentArea, St. Joseph-Elkhart Counties, Indiana. The United States Environmental Protection Agency (U.S. EPA) subsequently approved the Indiana redesignation ofthe South BendElkhart Area (including St. Joseph and Elkhart counties) to attainment for ozone on April18, 2007 (72 FR 19413). Omoad emissions for the May 30, 2006, submittal were calculated using MOBILE6.2. U.S. EPA has encouraged mobile source stakeholders to transition to the new Motor Vehicle Emissions Simulator (MOVES) model as expeditiously as possible. Therefore, IDEM is providing this MOBILE6.2 to MOVES replacement update to the previously submitted 8-hour ozone maintenance plan for the South Bend-Elkhart Area that incorporates MOVES-based omoad em1sswns. 

### Emission Inventory The table, "2010 and 2020 Projected Emission Inventory", was included in Appendix C ofthe original Redesignation Petition and Maintenance Plan. This table also included the year 2004 (the middle year ofthe area's attainment design value). The table, "2010 and 2020 Projected Emission Inventory- A", (to be considered a replacement ofthe table included in Appendix C) has been revised to incorporate updated omoad emission estimates for nitrogen oxides (NOx) and volatile organic compounds (VOCs) for the years 2004, 2010, and 2020; it results in a different overall safety margin for the area.

### Onroad emission estimates in the table, "2010 and 2020 Projected Emission Inventory- A", were calculated using U
.S. EPA's MOVES model-produced emission factors and data extracted from the area's travel-demand model. The MOVES model implements a significantly different approach to emissions estimation than the previous model (MOBILE6.2). Preliminary use ofthe MOVES model indicates that emission estimates can be considerably different than similar calculations using MOBILE6.2, which was used to create the original Motor Vehicle Emission Budgets (MVEBs) for the South Bend-Elkhart Area. A general summary ofthe MOVES methodology used in this area can be found in Appendix A. In addition, MOVES input and output files are being provided electronically with this submittal. Growth and control strategy assumptions for non-mobile sources (i.e. area, nonroad, and point) from the original submittal for the years 2004, 2010, and 2020 were developed before the economic challenges ofthe last several years. Because ofthis, the factors included in the original submittal may project more growth than will actually occur in the future. As a result, the growth and control strategy assumptions for the non-mobile sources for the years 2004, 2010, and 2020 continue to be valid and do not affect the overall conclusions ofthe plan. Onroad safety margins have been included for onroad emission estimates to accommodate the wide array ofassumptions that are factored into the calculation process. Since assumptions change over time, it is necessary to have an onroad safety margin that will accommodate the impact ofrefined assumptions in the process. The plan continues to meet all applicable Clean Air Act (CAA) requirements as the revised emission inventories clearly illustrate that total NOx and VOC emissions in the South Bend-Elkhart Area will continue to decline leading to local reductions between 2004 (base year) and 2020 (maintenance plan horizon).

### Through the interagency consultation process, it was determined that a maintenance plan horizon year budget of2020, would be appropriate. The interagency consultation group approved omoad margins ofsafety offifteen percent (15%) for both VOC and NOx omoad emission estimates for the year 2020. A summary ofthis interagency consultation discussion can be found in Appendix B. These revised emission inventories clearly illustrate that omoad VOC and NOx emissions in the South Bend-Elkhart Area will continue to decline leading to local reductions between 2004 (base year) and 2020 (maintenance plan horizon). Furthermore, when compared to the overall safety margin as defined in the Code ofFederal Regulations (CFR) at 40 CFR 93.101, it is evident the omoad safety margin allocation is reasonable and appropriate. More specifically, even with the allocation ofan omoad safety margin to mobile sources, emissions will continue to remain well below the overall safety margin for all sources in the South Bend-Elkhart Area as detailed in the table, "2010 and 2020 Projected Emission Inventory- A." 

### MVEBs are constrained to ensure that the total emissions (i.e., all source categories) do not exceed the 2004 attainment year emissions ofeither VOC or NOx, thereby ensuring continued maintenance ofthe 1997 8-hour ozone standard. Conclusion This MOBILE6.2 to MOVES replacement update to the previously submitted 8-hour ozone maintenance plan for the South Bend-Elkhart Area incorporates omoad emission estimates and a revised MVEB using U.S. EPA's recently adopted MOVES model. MVEBs have been revised in anticipation ofthe mandatory use ofthe MOVES model in future transportation conformity determinations. The omoad emission estimates were calculated using the MOVES-based emission factors and data extracted from the area's travel-demand model. Omoad safety margins for VOCs and NOx, established through the interagency consultation process, are included in order to account for the wide array ofassumptions that are factored into the calculation process. MVEBs are also constrained to ensure that total VOC and NOx emissions (i.e., all source categories) do not exceed attainment year (2004) emissions to ensure continued maintenance ofthe 1997 8-hour ozone standard. With the addition ofMOVES-based omoad safety margins applied to mobile sources, the South Bend-Elkhart Area will continue to remain well below the overall safety margins for all sources into the future. As such, the 8-hour ozone maintenance plan for the South Bend-Elkhart Area continues to meet all applicable CAA requirements.

## General Parameter Inputs The gene ral parameter inputs are the runspec parameters used to process emissions in MOVES. One runspec is generated for each county in the MACOG 8-Hour Ozone maintenance area and for each model year resulting in ten (10) to sixteen (16) run specifications for the model. Using a multiple runspec creator in MOVES2010, a batch file was created for running each runspec file (*.mrs) in succession without user intervention. When initially setting up a MOVES specification, it is best to proceed down the list oftabs

## Description A simple, general description of the various model runs detailing the horizon year, run type (inventory vs. rate), and the county being modeled by that run specification
.

A-3

## Scale Domain 

## I Scale A county scale was selected, and two model runs are made for each horizon year; one for Elkhart and one for St. Joseph County. This scale is intended for development ofthe State Implementation Plan (SIP) and the regional conformity analysis required for 8-hour ozone non-attainment and maintenance areas. 

### Calculation Type The emission rate calculation type was chosen over the inventory calculation type in order to provide rates for CMAQ modeling and project level modeling when necessary. A naming convention was established for flagging the numerous emissions rates generated for each county and model year. Using the MOVESScenarioiD field in the MOVES model, the county abbreviation followed by the model year was used, for example, Elk_2004 or SJC_2035. 

## Time Spans Time Aggregation Level Hour was selected following the parameters used by the Indianapolis MPO and agreed upon during an interagency consultation group {ICG) meeting. Statewide data is used to disaggregate the daily VMT from the MACOG travel demand model to hourly VMT as part ofthe post processing analysis. 

### Year A model run is generated for each year of emissions analysis with one (1) year being modeled in each run specification. The 2004 and 2010 model years are included for SIP development purposes. The 2004 model year represents the recorded pollutants in the air from the 2002-2004 time period used to designate the Elkhart and St. Joseph County area as a basic non-attainment area for the 8-hour ozone standard. The 2010 model year was used in the preparation of the SIP to meet the area's 2009 attainment year. Future years are modeled in 5 year increments from 2015 to 2035. 

### Months Only July is modeled in the emissions analysis, representing a typical summer day during the ozone season . July 1st was used for Mobile 6.2a modeling. 

### Days Weekdays are selected following the lead ofthe Indianapolis MPO. 

### Hours Emissions rates are generated for all hours ofthe day. 

## Geographic Bounds Elkhart County, Indiana and St. Joseph County, Indiana are individually selected for the region being modeled. A domain input database was selected for each county and horizon year, using the MOVESScenarioiD (lowercase) with an input suffix (i.e. elk_2004_input) to name the database.

A-4NOTE: The domain input database should be set after all other values in the run specification have been configured. The database is then generated under the Manage Input Data Set tab, the domain input database name under the Geographic Bounds tab is pointed to the database, and the County Data Manager under the Pre Processing menu is used to populate the database from the template files. 

## Vehicles/Equipment 

# I On Road Vehicles All valid gas and diesel combinations were included in the emissions modeling
. Any non-existent combinations (i.e. diesel motorcycles) were removed to eliminate the MOVES warning messages from the interface. 

## Road Type All road types were modeled. However, no off-road types are included in the travel demand model and are not a part of the resulting emissions. The MOVES Rural Restricted Access (2) road types include rural interstates and principal arterials as travel patterns of rural principal arterials should more closely resemble the travel patterns of a restricted access roadway
. Urban Restricted Access (4) road types include interstates, freeways, and expressways, but not primary arterials. Rural Unrestricted Access (3) and Urban Unrestricted Access (5) road types include all other arterials, collectors, and local roads
. 

## Pollutants 

# I Processes All processes were selected for total gaseous hydrocarbons, non-methane hydrocarbons, volatile organic compounds, carbon monoxide (CO), oxides of nitrogen (NOx), and total energy consumption
. Only the emissions for volatile organic compounds (VOC) and oxides of nitrogen (NOx) are required in the final analysis and calculated by the INDOT Air Quality Post-Processor. Total energy consumption and CO emissions are for informational purposes. 

## Strategies 

# IAlternative Vehicle Fuels & 

## Technology The MACOG region does not support any compressed natural gas (CNG) vehicles in the areas transit fleet. However, MOVES does consider a mix of CNG and gasoline engines in the transit mix, which can impact final emissions rates. To compensate, all bus sou rce types were adjusted to 100% diesel engines in the database. 

## Output 

# I General Output Database Name All output is stored in the macog_output database, which is deleted from MySQL and recreated in MOVES before generating a new set of emissions rates. Each run is flagged by a county abbreviation and the model year (Eik_2004, SJC_2035, etc) in order to identify and keep the individual model runs within the database separate. 

### Units The output units are in grams (mass units), joules (energy), and miles (distance) to prevent rounding errors from using larger units of measurement. Grams are later converted to short tons for reporting. A- 5

### Activity Only the grayed out defaults of d istance traveled and population are selected

### Analysis Year The analysis year drop down list is populated from a comma delimited file, yearlist.csv, with a column for each county and pollutant type. The list was recreated for St. Joseph (Sain_oz) and Elkhart's (Eikh_oz) ozone analysis years, which were not included in the default file from the State. 

### PeakSpreading Peak spreading was enabled in the interface. This allows for the INDOT Air Quality Post-Processor to spread the assigned VMT during the peak hour before and after the peak when it exceeds the hourly capacity ofthe roadway. 

### Scenario File

·The naming convention for the scenario files included the 4-character county abbreviation, analysis year being calculated, and the pollutant type (i.e. Elkh_2004_0zone). 

### Link Table The link tables are generated for both counties for each analysis year and consists of a subset of the street segment attributes joined with the trip assignments from the travel demand model. The link table consists ofthe following attributes:
• Lin kiD- The unique segment identifier assigned by TransCAD. • Dir- Identifies the link as a two-way segment (0), one-way segment (1), or a one-way segment that travels the opposite direction (-1) that the link was drawn in (BA rather than AB). • Length- The TransCAD calculated length ofthe segment. • County- The county code the link is found in (20 or 71), which is then converted into a name. • HPMS_FC- The FHWA functional classification of the segment. • ROAD_TYPE- The road type is based on the functional class of the corridor. Rural Restricted Access (2) road types include rural interstates and principal arterials as travel patterns of rural principal arterials should more closely resemble the travel patterns of a restricted access roadway
. Urban Restricted Access (4) road types include interstates, freeways, and expressways, but not primary arterials. Rural Unrestricted Access (3) and Urban Unrestricted Access (5) road types include all other arterials, collectors, and local roads. • AB_Aipha 

## I BA_Aipha- The alpha values were based on the hard coded values used in the travel demand model. • AB_Beta 

## I BA_Beta -The beta values were based on the hard coded values used in the travel demand model. • AB_FF_Time 

## I BA_FF_Time- • AB_CAP 

## I BA_CAP- The hourly capacity ofthe link is 1110th ofthe daily capacity of the segment. • AB_Veh_Fiow 

## I BA_Veh_Fiow- The daily flow ofvehicles on the link in the given direction. 

### Intrazonal Table The intrazonal tables are generated for both counties for each analysis year. The intrazonal table consists ofthe following attributes:

A-10• TAZ_ID- The unique identifier ofthe traffic analysis zone . • County- The county where the traffic analysis zone is located
. • Area_Type- Whether the TAZ is in an urban or rural area of the county. • Distance - The average length of intrazonal trips in the TAZ
. Calculated by determining the radius of a circle with an area equal to the area of the TAZ
. • Dly_lntrazonai_Trips- The daily intrazonal t rips generated by the TAZ but that do not leave the TAZ
. Calculated by finding the diagonal va lues ofthe 0-D matrix generated by the travel demand model. 

## Master Inputs Rate perDistance, Rate perProfile, Rate per Vehicle The emission rates for each county and analysis year are each queried out of the MOVES output database (macog_output) individually by em ission rate and saved as a comma delimited file using the 4- character county abbreviation, analysis year, emission type, and pollutant type to name the file in the Master Inputs folder (i.e. Elkh_2004_ratesperdistance_oz
.csv)
. 

### Source Type Population The source type population used as an input to the MOVES run specification is exported out of the template file as a comma delimited file using the 4-character county abbreviation, analysis year, and SourceTypePopulation (i.e
. Elkh_2004_SourceTypePopulation.csv). 

### Hourly VMTFraction The hou rly VMT fraction table was provided by INDOT and breaks down the fraction of VMT for each hour ofthe day by MOVES source type and road type. 

### HPMS Fractions The HPMS fraction table was provided by IN DOT and breaks down the distribution of the HPMS vehicle types by the FHWA functional classification of the road segment
. 

### Vehicle Class Distribution The vehicle class distribution table was provided by INDOT and breaks down the distribution of HPMS vehicle types by MOVES road types.

### Interagency Consultation Group (ICG) Conference Call Minutes
For the MOBILE6.2 to MOVES MVEB Replacement Update Related to the South Bend-Elkhart Maintenance Area under the 1997 8-Hour Ozone Standard ICG Conference Call Date and Time • May 10,2012 at 1pm Eastern ICG Attendees • Shawn Seals (IDEM), Patricia Morris (EPA), Steve Smith (INDOT), Larry Heil (FHWA), Vince Bernardin (BLA), Greg Katter (INDOT), Sandra Seanor (MACOG), John-Paul Hopman (MACOG), and Joyce Newland (FHWA) ICG Discussion Topics and Conclusions 1. For the Ozone MVEB Replacement submittal, various mobile source margins of safety were discussed. A. After discussion, the consensus ofthe ICG was that as long as the a 15% mobile source margin ofsafety for VOC and NOx emissions does not result in an exceedance ofthe all sources margins ofsafety, it was reasonable and appropriate for inclusion in MVEB Replacement submittal. The attached spreadsheet demonstrates that a 15% mobile source margin ofsafety for VOC and NOx emissions fall well below the all sources margins ofsafety and, as such, will be reflected in the Ozone MVEB Replacement submittal.
