Ms. Susan Hedman Regional Administrator U.S. Environmental Protection Agency Region 5 77 West Jackson Boulevard Chicago, IL 60604-3950 Dear Ms. Hedman: Re: Request to Parallel Process the Draft MOBILE6.2 to MOVES MVEB Replacement Update to the Indianapolis, Indiana 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 Indianapolis, Indiana Maintenance Area Underthe 1997 8-Hour Ozone Standard. The Indianapolis, Indiana maintenance area includes Boone, Hamilton, Hancock, Hendricks, Johnson, Madison, Marion, Morgan, and Shelby counties. IDEM requests that the United States Environmental Protection Agency (U.S. EPA) to 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 Indianapolis, Indiana maintenance area if a public hearing request is received by March 22, 2012. A hearing has been scheduled for March 29, 2012. If a request for a public hearing is not received by March 22, 2012, the hearing will be cancelled. The final submittal ofthe MVEB update for the Indianapolis, Indiana 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 Indianapolis, Indiana area's travel-demand model. MVEBs are being revised in anticipation ofthe mandatory use ofthe MOVES model in future transportation conformity determinations. Preliminary use of the new

### Ms. Hedman Page 2 model indicates that emission estimates can be considerably different than similar calculations using MOBILE6.2, which was used to create the MVEBs in the original ozone maintenance plan. Onroad 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 onroad 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 maintenance area of Indianapolis, Indiana 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. This submittal consists of one (1) hard copy of the required documentation. An electronic version of the submittal in PDF format that is identical to the hard copy has been sent to Pamela Blakley. IDEM respectfully requests that U.S. EPA proceed with final review of the MOBILE6.2 to MOVES MVEB replacement update and revised transportation conformity budgets and approval into Indiana's State Implementation Plan for the Indianapolis, Indiana Maintenance Area Under the 1997 8-Hour Ozone Standard. If you have any questions or need additional information, please contact Scott Deloney, Chief, Air Programs Branch, at (317) 233-5694. Sincerely,

# Onroad Emissions MOBILE6.2 to MOVES Replacement Submittal

Forthe Indianapolis, Indiana Maintenance Area Under the 1997 8-Hour Ozone Standard

### This page intentionally left blanl,

### Introduction On March 26, 2007, the Indiana Depaliment ofEnviromnental Management (IDEM) submitted a Request for Redesignation andMaintenance Planfor OzoneAttainmentin the 8-How' Ozone NonattainmentArea, Cenh'alIndianaArea. The United States Environmental Protection Agency (U.S. EPA) subsequently approved the Indiana redesignation ofthe Central Indiana Area to attainment for ozone on October 19,2007 (72 FR 59210). Onroad emissions for the March 26, 2007, 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 Central Indiana Area that incorporates MOYES-based onroad emissions. Emission InventOly
Table 4.1 was included without title in Appendix C ofthe original Redesignation Petition and Maintenance Plan. Table 4.1 - A (to be considered a replacement ofthe table included in Appendix C) has been revised to incorporate updated onroad emission estimates for the years 2005, 2010, 2015 and 2020; it results in a different overall safety margin for the area.

### Onroad emission estimates in Table 

### 4.1- A were calculated using U.S. EPA's MOVES modelproduced 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 differentthan similar calculations using MOBILE6.2, which was used to create the original MotorVehicle Emission Budgets (MVEBs) for the Central Indiana 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 2005, 2010,2015 and 2020 were developed before the down turn in the economy overthe 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 2005, 2010, 2015 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 overtime, 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 Central Indiana Area will continue to decline leading to local reductions between 2005 (base year) and 2020 (maintenance plan horizon).



### 2Tl"ansportation Conformity Bndgets Table 5.2 was included on Page 20 ofthe original Redesignation Petition and Maintenance Plan. Table 5.2 - A (to be considered a replacement ofTable 5.2) has been revised to incorporate MVEBs calculated using U.S. EPA's MOVES model-produced emission factors and data extracted ii'om the region's travel-demand model. Table 5.2 Motor Vehicle Emission Bndgets for the Central Indiana Area (MOBILE6.2-based Onroad Emissions) 2006 2020 NO, 106.19 35.69 VOC 54.32 29.52
Table5.2-A Motor Vehicle Emission Budgets for the Central Indiana Area (MOVES-based Onroad Emissions) 2006 2020 NOx 210.93 69.00 VOC 64.32 25.47 Through the interagency consultation process, it was determined that a maintenance plan horizon year budget of2020, would be appropriate. The interagency consultation group approved onroad margins ofsafety often percent (10%) for NOx and twelve percent (12%) for YOC onroad 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 onroad NOx and YOC emissions in the Central Indiana Area will continue to decline leading to local reductions between 2005 (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 onroad safety margin allocation is reasonable and appropriate. More specifically, even with the allocation ofan onroad safety margin to mobile sources, emissions will continue to remain well below the overall safety margin for all sources in the Central Indiana Area as detailed in Table 4.1

- A. MYEBs are constrained to ensure that the total emissions (i.e., all source categories) do not exceed the 2005 attainment year emissions ofeitherNOx or YOC, thereby ensuring continued maintenance ofthe 1997 8-hour ozone standards. Conclusion This MOBILE6.2 to MOYES replacement update to the previously submitted 8-hour ozone maintenance plan for the Central Indiana Area incorporates onroad emission estimates and a revised MYEB using U.S. EPA's recently adopted MOVES model. MYEBs have been revised in anticipation ofthe mandatory use ofthe MOVES model in future transpOliation conformity

Onroad safety margins for NOx and VOCs, established through the interagency consultation process, are included in orderto account for the wide array ofassumptions that are factored into the calculation process. MVEBs are also constrained to ensure that total NOx and VOC emissions (i.e., all source categories) do not exceed attainment year (2005) emissions to ensure continued maintenance ofthe 1997 8-hour ozone standard. With the addition ofMOVES-based onroad safety margins applied to mobile sources, the Central Indiana Area will continue to remain well below the overall safety margins for all sources into the future. As such, the 8-holll' ozone maintenance plan for the Central Indiana Area continues to meet all applicable CAA requirements.

# Introduction

The purpose of the ail' quality pre- and post-processor update was to transition from the current MOBILE6.2 based emissions module within the Indianapolis travel demand model (TOM) to MOVES201Oa, the U.s. Environmental Protection Agency's (EPA) Motor Vehicle Emissions Simulator (MOVES) model. FtI1'ther detail on the input data and planning assumptions used to I'tIn MOVES2010a, as well as the structure of the ail' quality pre- and post-processor (ail' quality module) within the TOM, are provided below. A user's guide to running the TOM ail' quality module is included as an appendix.

# 1.0 MOVES Input Data and Planning Assumptions

In order to automate the calculation ofozone and PM,.5emissions within the TDM post-processor, MOVES201Oa was run in emission rate mode providing emission rates thatwere used as inputfiles into theTDM post-processor and then applied to pre-processed h'avel activity data within the TDM to calculate emissions. Unless inputs into MOVES change, for example, fuel formulation data 01' a new inspection and maintenance 

## (IfM) program in the Indianapolis area, it should not be necessalY to run MOVES again until the nextfull update ofthe Indianapolis LongRangeTransportationPlan (LRTP) 01' evelY five years ata minimum. 

# 1.1 AIR QUALITY ANALYSIS YEARS Since the base validation year of the Indianapolis TDM is 2010, MOVES201Oa was run for 2015, 2020, and 2025 representing future year runs necessary to created MOVES-based emissions for input into the PM,.5 and Ozone Motor Vehicle Emissions Budgets (MVEB) as part of the State Implementation Plans (SIP). MOVES-based emissions for ail' quality years required prior to the base year ofthe model (Le., 2002, 2005, 2006, and 2008) will be calculated off-model by the Indianapolis MPO. Figure 1.1 illush'ates why each ofthe ail' quality analysis years were chosen. It should be noted thatyear 2035 is the CUl'l'entLRTP horizon year and as such, the Indianapolis

# TOM Pre- and Post-Processor

Emission rates generated by MOVES are used as inputs to the TDM postprocessor. The TDM air quality model, or emissions module, which contains both t1,e TOM pre- and post-processor can be run from t1,e MPO model interface by checking the "Air Quality" option in the "Assignment" stage of t1,e TDM's user interface. The entire process takes approximately 10 to 15 minutes to run depending on t1,e computer system's specifications. The TOM pre-processorprovides some inputs to MOVES, such as VMT and road type distribution. Once emission factors are generated from MOVES, the emission factors are reformatted wit1,in t1,e TOM in order to sh'eamline t1,e reading of the factors within the GISOK script and to get them in the format needed to apply to the travel activity data. The TOM pre-processor prepares the travel activity data on t1,e model links in order to apply these factors and then the TOM post-processor calculates and summarizes both the running and nonrunning emissions. Figure 2.1 illush'ates the overall emissions calculation process, while Figure 2.2 illustrates additional detail within each step.

# 2.1 INCLUDED COUNTIES TheTDM airquality model generates daily running emissions atthe county level and atthe Highway Performance Monitoring System (HPMS) functional class level. Itgenerates the non-running daily emissions atthe regional level based on vehicle popuiation data. The counties includedwithin the Indianapolis MPO boundary are: Marion, Hamilton, Johnson, Hendricks, Hancock, Shelby, Boone, Morgan, and Madison. The Anderson MPO TDM generates daily running emissions for Madison County. Historically, running emissions for Madison County have been calculated off-model bythe Anderson MPO using MOBILE6.2 emission rates provided by the Indianapolis MPO. Similarly with MOVES, the Indianapolis MPO will providethe Anderson MPO with MOVES emission rates fortheAnderson MPO to calculate Madison County running emissions and provide backto the Indianapolis MPO for inclusion in the overall Conformity Determination Report (CDR) for the entire Indianapolis nonattainmentareas. The Indianapolis MPO will calculate non-running emissions for Madison County usingvehicle populations from INDOTand the same non-running emissions rates used for the othercounties. As a result, the TDM airquality module does not output running emissions for Madison County, but does output non-running emissions for Madison County. The Ozone nonattainment area includes all nine counties and the PM,., nonattainment area includes Hamilton, Hendricks, Johnson, Marion, and Morgan Counties. Therefore, PM,., emissions output from the TDM air quality module for the otherfour counties (Hancock, Shelby, Boone, and Madison Counties) are set to zero. 

# 2.2 AIR QUALITY MODULE SCRIPT STRUCTURE (MACROS) The air quality post-processing script was written in GISDK to make it compatible with the other components of the TransCAD model. The ail' quality module script is embedded in the macro titled "AQ" within the overall model stream script. Itcalls tile following macros:

• Set_HPMS: Sets tile HPMS functional class code in tile line layer of the model network based on specified Facility Type and Area Type combinations on each link.

• ReadFiles: Reads the inputfiles and stores the input data in arrays.

•**Calculate_NonRunnin~Emissions:** Calculates the daily non-running emissions based on emission rates generated by MOVES and the vehicle population within tile MPO model boundary.

• Create_MOVES_RD_TYPE: Populates eacll network link Witll a MOVES road type code based on an HPMS functional class code equivalency table.

• CalculateIntrazonalVMT: Calculates inh'azonal Vehicle Miles Traveled (VMT) based on intrazonal travel distance and inh'azonal trips, The intrazonal VMT includes all h'avel activity tllat begin and end within tile

State ojIndia/w same traffic analysis zone and it is calculated for each time period and for both AB and BA directions.
• . Calculate_hpms_adjjactor: Calculates adjustmentfactors based on the ratio of HPMS VMT to the model VMT. The adjustmentfactors are calculated for each ofthe HPMS hUlctionai class codes and for each ofthe nine counties. Based on previous interagency consultation discussions, HPMS adjustmentfactors are not currentlyusedby tile Indianapolis MPO and as such, tllesefactors are setto 1.0.

• Calculate_Speed_Bin: Sets tile speed bins for each network link based on congested model speeds for different times of day. It uses the five mile per hour (mph) speed bin ranges defined in MOVES to determine the speed bins for the networklinks.

•**Caiculate_Runnin~Emissions:** TItis macro calculates the daily rwlning emissions by applying theentissionrates generated byMOVES to the weightedVMT.

• Summaty: Summarizes the daily emissions by functional class and county. Figure 2.3 illustrates tile flow diagram ofGISDK scriptfor the air quality module.

The following subsections provide further detail on eachmacro, or subroutine. 

### Setting the HPMS Functional Classification The air quality module sets the HPMS functional class code for eachnetwork link based on its area type and facility type combination. Table 2.1 lists each ofthese combinations and their assigned HPMS functional classification code.

State of Indiana 2-5

### Table 2.1 HPMS Functional Class Codes Assigned Based on Area Type and Facility Type Combinations HPMS Functional Class Area Type FacilityType 5 1,7,8,9,10,11,12 2 5 2,4,6 6 5 3 9 5 5 11 1,2,3,4 1,7,8,9,10,11,12 12 1,2,3,4 2 14 1,2,3,4 4,6 16 1,2,3,4 3 19 1,2,3,4 5
The assignment ofHPMS Functional Class codes to each link in the network provides: 1. An equivalency attribute for MOVES road type codes, and 2. The ability to calculate HPMS adjustment factors by HPMS functional class if desired. 

### Reading Input Data The air quality module reads the input files and stores the input data in multidimensional anays. Table 2.2 provides a description of the input data.

### Calculate Non-Running Emissions The non-running emissions are produced by

- vehicles when they are not in motion. The calculation process uses [ratepervehicle], [rateperprofile] and the vehicle population as input. It calculates the emission based on the following equations: 

### Daily non-TUnning emissions 

### by pollutant 

### = emissionfrom rate per vehicle by pollutant+

### emissionfl'Om rateperprofile bypollutant emission fl'Om rate per vehicle by pollutant = 

### Ihoul'IsourceIprocess rateperuehicle*vehiclepopulation emission fl'Om rate per pl'Ofile by pollutaHt 

### = IhourIsource rateperprofile* vehiclepopulation In order to calculate Ozone emission which includes NO, and VOC, it uses the total vehicle population in all nine counties. PM'.5 rates are applied to the vehicle population of five counties. The non-rurming emissions are stored in the array variable, NREmissions[pollutantindex]. 

### Create MOVES Road Type The MOVES road type is set based on the functional class. Below is the script thatprovides the criteria for assigning MOVES road type codes:

### IfHPMS 

### = 11 

### orHPMS= 12 

### tllen MOVES_TYPE

### where MOVES_TYPE

### or (HPMS= 2 

### andfacility type =2) 

### then MOVES3YPE = 2 

### where MOVES_TYPE = 2 

### for rural restrictedaccess IfHPMS > 12 

### then MOVES_TYPE 

### = 5

### =5

### for urban unrestrictedaccess If(HPMS >2 

### andHPMS <=9) 

### or (HPMS = 2 

### and FACILTY_TYPE<>2) where MOVES_TYPE = 3

### for rural unrestrictedaccess It was noticed in the model network that the roadways with an HPMS functional class code 

### = 2 can be both restricted-access and unresh'icted-access roadways, Therefore, the ath'ibute "facility type" is used to differentiate between the roadways with restricted-access and the roadways with unresh'icted-access, Table 2,3 illush'ates the HPMS Functional Class to MOVES Road Type equivalency table,

### Calculate Intrazonal VMT The ail' quality module calculates the model VMT by using assigned flow and the length of the network links. The model generates assigned flow table for three different time periods: a.m., p.m. and off-peak. Table 2.4 demonsu'ates the time spans ofeach time period. 

### Table 2.4 Hours Within Each Time Period

State of 1l1dimw The intrazonal VMT at each TAZ is calculated from the time of day u'ip tables and the intrazonal distance skim. The inu'azonal distance skimis generated from the shortest path based on congested u'avel time. In order to get the intrazonal skim, the average distance to the tlu'ee nearest neighboring zones were multiplied by a factor of 0.5. The intrazonal VMT at each TAZ is distributed to the cenu'oid connectors based on their share of the assigned VMT, The inu'azonal VMT on each link connector is calculated from the following equations: 

### AB/BA InrazonalVMT for centroidconnectori= 

### IntrazonalVMTat TAZ *

### share of assigned VMTali 

### share ofassigned VMTat i = 

### (AB/BA assignedflaw)/(sum ofthe assignedflow ateach centroidconnectors oftile TAZ)

2-9The calculated inh'azonal VMT at each link are then added to the assigned VMT ofthat link. The daily VMT on each link is being calculated by adding the VMTs ofthree time ofday periods.

### Calculate HPMS Adjustment Factor The model VMT gets adjusted by the HPMS VMT. provided by INDOT. The HPMS VMTs are available by counties and by HPMS functional classes. The air quality module sets the HPMS adjushnent factors for each of the network links by using the county and the HPMS functional class attribute of that link. The default value of HPMS adjushnent factor is 1. HPMS adjushnent factor is calculated by using the following equation: 

### HPMS_ADIJACT for counn) c

### andHPMSfunctional class h 

### = (HPMS VMT for c

### andh)/(sum of model VMT for c

### andh) 

### Calculate Speed Bin The air quality module sets the speed for each network link based their congested speeds. The congested speed for each link is calculated from the link length and the congested h'avel time. The congested travel time is generated by the highway assignment component of the model. The speed varies by time of day periods and by the direction offlow. Therefore, speed bin is determined for each time ofday periods and for each ofAB and BA direction. The speed bin for each link is being setby using the following criteria identified in Table 2.5. 

### Table 2.5 Speed Ranges Within Each Speed Bin 

### Calculate Running Emissions The running emissions are generated from the moving vehicles. The running emission is calculated from rate per distance, travel data and the network ath·ibutes. It uses the following equation to calculate running emission for each ofthe network link: 

### Daily rUllI1ing emission by pollutant = 

### I,llOurI,HPMS Veh Class (hourly adjustedvmt * 

### I,process rateperdistance) Where ratepel'distance depends on speedbins andMOVES roadn)pe

State aflndiana 2-10In order to facilitate the calculation process, the air quality module creates a database titIed EMIS_daily.bin. Each record in this me can be identified by network linkIds. Table 2.6 describes the fields in the database EMIS_Daily.bin.

State aflndiana The running emission is calculated for each ofthe network links from rate per distance and the adjusted VMT. The rate per distance varies with hours of day, MOVES source type, MOVES road types, speed bins, emission processes and pollutants. The emission rate is calculated for each of the HPMS vehicle type categories. In order to do that, the program aggregates the rates by 13 MOVES source types to the rates by 6 HPMS vehicle classes be using a weighting factor. The factor is calculated from the array variable, MOVES_Frac, as described earlier in Table 2.2. This array stores the fraction ofVMT by MOVES road type and MOVES source (vehicle) type. As a result, tile weighting factor varies with MOVES road types and MOVES vehicle types. The factor is calculated by using the following equation: 

### The weightingfactor = 

### MOVES_Fmc[road type index4][HPMS vehicle class index6][2nd digit of source type]/2,MOVESJrac[road type index4][HPMS vehicle class index6] For each link of the network, the air quality module looks up the emission rates from the array variable, rateperdistance, by using the attributes such as the speed bins and road types for each MOVES source (vehicle) type, emission process, pollutant and hour of the day. The following flow chart (Figure 2.4) describes the process ofcalculating daily emissions by pollutantby HPMS vehicle classes. The air quality module populates tIu'ee new fields in the network's line layer: 

### Daily_NOx_peUl1ile, Daily_VOC,...peUl1i1e, and 

### DAlLY_PM25,...peuni1e. These fields show tile rUlUling emissions per mile for each link.

ICG Discussion Topics and Conclnsions I. The question ofwhether or not non-running emissions should be included in MVEBs as we move forward was raised. A. It was determined by consensus ofthe lCG that both running and non-running emissions were appropriate for inclusion in the MVEBs. B. A revised ICG discussion spreadsheet was subsequently developed to include an additional line oftotals with both running and non-running emissions that are included as the baseline for the mobile source margins ofsafety and the all source margin ofsafety discussions. 2. The question ofusing one annual run, or four seasonal runs was raised. A. After discussion ofthe lCG, the consensus was the one annual run was reasonable and appropriate for MOVES runs. 3. Forthe PM2.5 MVEB Replacement submittal, various mobile source margins of safety were discussed. A. The originally submitted PM2.5 SIP submittal included a 22% mobile source margin ofsafety that was inflated for the purpose ofaccommodating the uncertainties ofthe transition from 2004 to 2009 Indiana vehicle fleet mix. B. After discussion, the consensus ofthe ICG was that as long as a 15% for PM2.5 and NOx mobile source margin ofsafety did not result in an exceedance ofthe all sources margin ofsafety, it was reasonable and appropriate for inclusion in MVEB Replacement submittal. The subsequent spreadsheetmentioned above demonstrated that a 15% mobile source margin ofsafety falls well below the all sources margin ofsafety and, as such, will be reflected in the PM2.5 MVEB Replacement submittal. 4. For the Ozone MVEB Replacement submittal, various mobile source margins of safety were discussed.



### B-1

### A. The originally submitted Ozone SIP submittal included a 12% mobile source margin ofsafety for YOC, with a 10% margin ofsafety for NOx. B. After discussion, the consensus ofthe ICG was that as long as the existing 12% for YOC and 10% for NOx mobile source margins ofsafety do not result in an exceedance ofthe all sources margins ofsafety, it was reasonable and appropriate for inclusion in MVEB Replacement submittal. The attached spreadsheetdemonstrates that a 12% for YOC and 10% for NOx mobile source margins ofsafety fall well below the all sources margins ofsafety and, as such, will be reflected in the Ozone MYEB Replacement submittal. C. After further study, Indy MPO requested additional time to conduct a 2035 MOYES-based emissions projection to confirm thatthe recommended mobile source margins ofsafety for the Ozone SIP submittal will be adequate farther into the future. Afterthe 2035 projection was complete, itwas confirmed that the recommended mobile source margins ofsafety for the submittal would be adequate.
