Re: MOBILE6.2 to MOVES MVEB 

Replacement Update to the Request for 

Redesignation Petition and Maintenance 

Plan Under the Annual National Ambient 

Air Quality Standard for Fine Particles for 

the Central Indiana Nonattainment Area 

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 Request for Redesignation 

Petition and Maintenance Plan Under the Annual National Ambient Air Quality Standard 

for Fine Particles for the Central Indiana Nonattainment Area. The Central Indiana 

nonattainment area includes Hamilton, Hendricks, Johnson, Marion, and Morgan 

counties. This request for redesignation was submitted to the United States 

Environmental Protection Agency (U.S. EPA) on May 31, 2011, and has not yet been 

acted upon. IDEM requests that U.S. EPA process this final submittal for approval into 

Indiana's previously submitted request for redesignation under the annual fine particles 

standard. 

IDEM provided an opportunity for a public hearing on the MVEB replacement 

update to the Central Indiana nonattainment area if a public hearing request was 

received by January 2, 2013. A hearing was scheduled for January 9, 2013. No request 

for a public hearing was received and the hearing was cancelled. In addition, IDEM 

received no public comments during the public notice process. Documents related to the 

public participation process are included in Appendix C of this submittal.

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 Central Indiana 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 

calculations using MOBILE6.2, which was used to create the MVEBs in the original 

annual fine particle redesignation request. 

Onroad safety margins, established through the interagency consultation process, 

are included for fine particulate matter (PM2 5) and nitrogen oxides (NOx). These on road 

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 onroad safety margins applied to mobile sources, the Central Indiana area will 

continue to remain well below the overall safety margins for all sources. MVEBs are also 

constrained to ensure that total PM2.5 and NOx emissions (i.e., all source categories) do 

not exceed attainment year emissions, to ensure continued maintenance of the annual 

national ambient air quality standard for fine particles. 

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 review of the MOBILE6.2 

to MOVES MVEB replacement update and revised transportation conformity budgets and 

approval into Indiana's Request for Redesignation Petition and Maintenance Plan Under 

the Annual National Ambient Air Quality Standard for Fine Particles for the Central 

Indiana Nonattainment Area of May 31, 2011. If you have any questions or need 

additional information, please contact Scott Deloney, Chief, Air Programs Branch, at

Onroad Emissions MOBILE6.2 to 

MOVES Replacement Submittal 

For the Indianapolis, Indiana 

Maintenance Plan Under the Annual 

National Ambient Air Quality 

Standard for Fine Particles 

FINAL 

November 2012 
This page intentionally left blank 
Introduction 

On May 31, 2011, the Indiana Department ofEnviroumental Management (IDEM) submitted a 

Request for Redesignation and Maintenance Plan Under the Annual National Ambient Air 

Quality Standard for Fine Particles for the Central Indiana Area. The United States 

Environmental Protection Agency (U.S. EPA) has not yet approved the Indiana redesignation of 

the Central Indiana Area to attainment under the annual national ambient standard for fine 

pmticles. Onroad emissions for the May 31, 20 II, 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 Request 

for Redesignation and Maintenance Plan Under the Annual National Ambient Air Quality 

Standard for Fine Particles for the Central Indiana Area that incorporates MOVES-based onroad 

emiSSIOnS. 

Emission Inventory 

The tables titled, 2008 Central Indiana Area, 2015 Central Indiana Area, 2020 Central Indiana 

Area, and 2025 Central Indiana Area, were included in Appendix E ofthe original Redesignation 

Petition and Maintenance Plan. The consolidated table titled, 2008, 2015,2020, and 2025 Central 

Indiana Area All Anthropogenic Sources in Tons Per Year (to be considered a replacement of the 

existing separate 2008,2015, 2020, and 2025 tables included in Appendix E as detailed above) has 

been revised to incorporate updated omoad emission estimates for fine pmticulate matter (PM2.5) 

and nitrogen oxides (NOx) for the years 2008, 2015,2020, and 2025 and results in a different 

overall safety margin for the area. It should be noted that although sulfur dioxide (S02) emissions 

are included in the Appendix E tables, consistent with the federal implementation mle for fine 

particles, Indiana does not consider mobile source S02 to be a significant contributor to fine 

particles for this nonattainment area, as mobile source S02 constitutes less than 1.2% ofthe area's 

total anthropogenic emissions. As such, S02 emissions are not included in the table titled, 2008, 

2015, 2020, and 2025 Central Indiana Area All Anthropogenic Sources in Tons Per Year.

Omoad emission estimates in the table titled 2008, 2015, 2020, and 2025 Central Indiana Area 

All Anthropogenic Sources in Tons Per Year, 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 of the 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 Central Indiana 

Area. A general summary of the 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 2008, 2015, 2020, and 2025 were 

developed before the downtum in the economy over the last several years. Because of this, 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 2008, 2015, 2020, and 2025 continue to be valid and do not affect the overall 

conclusions of the plan. 

Onroad safety margins have been included for onroad emission estimates to accommodate the 

wide array of assumptions that are factored into the calculation process. Since assumptions 

change over time, it is necessary to have an omoad safety margin that will accommodate the 

impact of refined 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 PM2.5 

and NOx emissions in the Central Indiana Area will continue to decline leading to local 

reductions between 2008 (attainment/base year), 2015 (interim year), and 2025 (maintenance 

plan horizon year).

Transportation Conformity Budgets 

Table 5.2 was included on Page 26 of the original Redesignation Petition and Maintenance Plan. 

Table 5.2- A (to be considered a replacement of Table 5.2) has been revised to incorporate 

MVEBs calculated using U.S. EPA's MOVES model-produced emission factors and data extracted 

from the region's travel-demand model.

Through the interagency consultation process, it was determined that an interim budget year of 

2015 and a maintenance plan horizon budget year of2025, would be appropriate. The interagency 

consultation group approved a fifteen percent (15%) margin of safety for omoad PMz.s and NOx 

emission estimates for the years 2015 and 2025. A summary of this interagency consultation 

discussion can be found in Appendix B. These revised emission inventories clearly illustrate that 

omoad PM2.5 and NOx emissions in the Central Indiana Area will continue to decline leading to 

local reductions between 2008 (attainment/base year), 2015 (interim year), and 2025 (maintenance 

plan horizon year). 

Fmthermore, when compared to the overall safety margin as defined in the Code ofF ederal 

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 of an omoad 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 the table titled, 2008, 2015, 2020, and 2025 

Central Indiana Area All Anthropogenic Sources in Tons Per Year. MVEBs are constrained to 

ensure that the total emissions (i.e., all source categories) do not exceed the 2008 attainment/base 

year emissions of either PM2.5 or NOx, thereby ensuring continued maintenance of the annual 

national ambient standard for fine patticles. 

7 
Conclusion 

This MOBILE6.2 to MOVES replacement update to the previously submitted Request for 

Redesignation and Maintenance Plan Under the Annual National Ambient Air Quality Standard 

for Fine Particles for the Central Indiana Area incorporates onroad emission estimates and a 

revised MVEB using U.S. EPA's recently adopted MOVES model. MVEBs have been revised in 

anticipation of the mandatory use of the MOVES model in future transpmiation confmmity 

detetminations. The onroad emission estimates were calculated using the MOVES-based emission 

factors and data extracted from the area's travel-demand model. Onroad safety margins for PM2.s 

and NOx, established tiu·ough the interagency consultation process, are included in order to account 

for the wide anay of assumptions that are factored into the calculation process. MVEBs are also 

constrained to ensure that total PM2_5 and NOx emissions (i.e., all source categories) do not exceed 

attainment/base year (2008) emissions to ensure continued maintenance of the annual national 

ambient standard for fine particles. With the addition of MOVES-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 Request for Redesignation and 

Maintenance Plan Under the Annual National Ambient Air Quality Standardfor Fine Particles for 

the Central Indiana Area continues to meet all applicable CAA requirements.

Introduction 

State of Indiana 

The purpose of the air quality pre- and post-processor update was to transition 

from the current MOBILE6.2 based emissions module within the Indianapolis 

travel demand model (TDM) to MOVES2010a, the U.S. Environmental Protection 

Agency's (EPA) Motor Vehicle Emissions Simulator (MOVES) model. Further 

detail on the input data and planning assumptions used to run MOVES2010a, as 

well as the sh·ucture of the air quality pre- and post-processor (air quality 

module) within the TDM, are provided below. A user's guide to running the 

TDM air quality module is included as an appendix. 

1-1 
1.0 MOVES Input Data and 

Planning Assumptions 

In order to automate the calculation of ozone and PM2.semissions within the TDM 

post-processor, MOVES2010a was run in emission rate mode providing emission 

rates that were used as input files into the TDM post-processor and then applied to 

pre-processed travel activity data within the TDM to calculate emissions. Unless 

inputs into MOVES change, fm example, fuel formulation data or a new inspection 

and maintenance (I/M) program in the Indianapolis area, it should not be 

necessary to run MOVES again until the next full update of the Indianapolis LongRange Transportation Plan (LRTP) or every five years at a minimum. 

1.1 AIR QUALITY ANALYSIS YEARS 

State of Indiana 

Since the base validation year of the Indianapolis TDM is 2010, MOVES2010a 

was run for 2015, 2020, and 2025 representing future year runs necessary to 

created MOVES-based emissions for input into the PM2.s and Ozone Motor 

Vehicle Emissions Budgets (MVEB) as part of the State Implementation Plans 

(SIP). MOVES-based emissions for air quality years required prior to the base 

year of the model (i.e., 2002, 2005, 2006, and 2008) will be calculated off-model by 

the Indianapolis MPO. Figure 1.1 illustrates why each of the air quality analysis 

years were chosen. It should be noted that year 2035 is the current LRTP horizon 

year and as such, the Indianapolis MPO will be required to run MOVES at a later 

time fm the purpose of the regional emissions analysis to complete their 

conformity determination.

1 It should be noted that while emission rate mode was chosen early in the course of the project, the project 

team later became aware of some bugs in EPA's MOVES emission rate calculations associated with the VOC 

refueling process and PM2.5 tirewear process. While these calculation errors internal to MOVES are believed 

to result in only slightly different emissions results than if MOVES were run in Inventory mode, the exact size 

of the differences are unknovvn at this point.

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 the TDM pre- and post-processor can be run from the MPO model interface 

by checking the "Air Quality" option in the "Assigmnent" stage of the TDM's 

user interface. The entire process takes approximately 10 to 15 minutes to run 

depending on the computer system's specifications. 

The TDM pre-processor provides some inputs to MOVES, such as VMT and road 

type distribution. Once emission factors are generated from MOVES, the 

emission factors are reformatted within the TDM in order to streamline the 

reading of the factors within the GISDK script and to get them in the format 

needed to apply to the travel activity data. The TDM pre-processor prepares the 

travel activity data on the model links in order to apply these factors and then 

the TDM post-processor calculates and summarizes both the running and nonrunning ermsswns. Figure 2.1 illustrates the overall emissions calculation 

process, while Figure 2.2 illustrates additional detail within each step.

wil be calculated sepa<ately from the Indy MPO travel demand model. However, VMT from the Anderson MPO travel demand model are input into MOVES to calculate emissions factors that will be 

applied to the Madison MPO model travel activity data It is anticipated that Madison County emissions will be added back in to the regional emissions outside the Indy air quality postprocessor.

vehicle types are then aggregated to the 6 HPMS vehicle type categories by applying the weighted average to the rate. Total VMT from the Indy model is disaggregated to the 6 HPMS vehicle type 

categories by using the percent of VMT by vehicle type from HPMS data for the County. The weighted average emissions factor at the HPMS level is then applied to the disaggregated model VMT by 

HPMS vehicle type.

2.1 INCLUDED COUNTIES 

The TDM air quality model generates daily running emissions at the county level and at the Highway 

Performance Monitoring System (HPMS) functional class level. It generates the non-running daily emissions 

at the regional level based on vehicle population data. The counties included within 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 by the Anderson MPO using MOBILE6.2 emission rates 

provided by the Indianapolis MPO. Similarly with MOVES, the Indianapolis MPO will provide the Anderson 

MPO with MOVES emission rates for the Anderson MPO to calculate Madison County running emissions and 

provide back to the Indianapolis MPO for inclusion in the overall Conformity Determination Report (CDR) for 

the entire Indianapolis nonattainment areas. The Indianapolis MPO will calculate non-running emissions for 

Madison County using vehicle populations from IN DOT and the same non-running emissions rates used for 

the other counties. As a result, the TDM air quality 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 PM2.5 nonattainment area includes 

Hamilton, Hendricks, Johnson, Marion, and Morgan Counties. Therefore, PM2.5 emissions output from 

the TDM air quality module for the other four 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 air quality 

module script is embedded in the macro titled "AQ" within the overall model 

sh·eam script. It calls the following macros: 

• Set_HPMS: Sets the HPMS functional class code in the line layer of the 

model network based on specified Facility Type and Area Type combinations 

on each link. 

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

• Calculate_NonRunning_Emissions: Calculates the daily non-running 

emissions based on emission rates generated by MOVES and the vehicle 

population within the MPO model boundary. 

• Create_MOVES_RD_TYPE: Populates each network link with 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 intrazonal trips. The 

intrazonal VMT includes all travel activity that begin and end within the 

State of Indiana 2-3 
State of Indiana 

same traffic analysis zone and it is calculated for each time period and for 

both AB and BA directions. 

• Calculatejlpms_adj_factor: Calculates adjustment factors based on the ratio of 

HPMS VMT to the model VMT. The adjustment factors are calculated for each 

of the HPMS functional class codes and for each of the nine counties. Based on 

previous interagency consultation discussions, HPMS adjustment factors are not 

currently used by the Indianapolis MPO and as such, these factors are set to 1.0. 

• Calculate_Speed_Bin: Sets the 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 network links. 

• Calculate_Running_Emissions: This macro calculates the daily running emissions 

by applying the emission rates generated by MOVES to the weighted VMT. 

• Summary: Summarizes the daily emissions by functional class and county.

Setting the HPMS Functional Classification 

The air quality module sets the HPMS functional class code for each network link 

based on its area type and facility type combination. Table 2.1lists each of these 

combinations and their assigned HPMS functional classification code.

State of Indiana 

1. An equivalency ath·ibute 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 arrays. 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-running emissions by pollutant = emission from rate per vehicle by 

pollutant + emission from rate per profile by pollutant 

emission from rate per vehicle by pollutant = L,hourL,source2)rocess 

ratepervehicle* vehicle population 

emission from rate per profile by pollutant = L,lwurL,source rateperprofile* 

vehicle population 

In order to calculate Ozone emission which includes NOx and VOC, it uses the 

total vehicle population in all nine counties. PM2.s rates are applied to the vehicle 

population of five counties. The non-running emissions are stored in the array 

variable, NREmissions[pollutant index]. 

Create MOVES Road Type 

The MOVES road type is set based on the functional class. Below is the script 

that provides the criteria for assigning MOVES road type codes: 

2-7 
State of Indiana 

IfHPMS = 11 or HPMS= 12 then MOVES_TYPE = 4 where MOVES_TYPE 

= 4 for urban restricted access 

If HPMS = 1 or (HPMS= 2 and facilih; h;pe =2) then MOVES_TYPE = 2 

where MOVES_TYPE = 2for rural resb·icted access 

If HPMS > 12 then MOVES_TYPE = 5 where MOVES_TYPE = 5 for urban 

unrestricted access 

If (HPMS >2 and HPMS <=9) or (HPMS = 2 and FACILTY_TYPE<>2) where 

MOVES_TYPE = 3 for rural unrestricted access 

It was noticed in the model network that the roadways with an HPMS 

functional class code = 2 can be both restricted-access and unrestricted-access 

roadways. Therefore, the attribute "facility type" is used to differentiate 

between the roadways with restricted-access and the roadways with 

um·estricted-access.

Type equivalency table.

Calculate Intrazonal VMT 

The air 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 demonstrates the time 

spans of each time period. 

Table 2.4 Hours Within Each Time Period 

The intrazonal VMT at each TAZ is calculated from the time of day trip tables 

and the inh·azonal distance skim. The intrazonal distance skim is generated from 

the shortest path based on congested travel time. In order to get the intrazonal 

skim, the average distance to the three nearest neighboring zones were 

multiplied by a factor of 0.5. The intrazonal VMT at each TAZ is distributed to 

the cenh·oid connectors based on their share of the assigned VMT. The 

intrazonal VMT on each link connector is calculated from the following 

equations: 

ABjBA InmzonalVMT for centroid connector i= IntrazonalVMT at TAZ *share 

of assigned VMT at i 

share of assigned VMT at i = (AB/BA assigned flow)j(sum of the assigned flow 

at each centroid connectors of the TAZ) 

2-9 
T11e calculated intrazonal VMT at each link are then added to the assigned VMT 

of that link. The daily VMT on each link is being calculated by adding the VMTs 

of three time of day periods. 

Calculate HPMS Adjustment Factor 

The model VMT gets adjusted by the HPMS VMT. The HPMS VMTs are 

pmvided by INDOT. The HPMS 

VMTs are available by counties 

and by HPMS functional classes. 

The air quality module sets the 

HPMS adjustment 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 

adjustment factor is 1. HPMS 

adjustment factor is calculated by 

using the following equation:

6 

HPMS_ADJ_FACT for county c and HPMS functional class h ~ (HPMS VMT 

for c and h)/( sum of model VMT for c and h) 

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 travel 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 of flow. Therefore, speed bin is determined for 

each time of day periods and for each of AB and BA direction. The speed bin for 

each link is being set by using the following criteria identified in Table 2.5. 

Table2.5 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 

attributes. It uses the following equation to calculate running emission for each 

of the network link: 

Daily running emission by pollutant ~ "LJwuri,HPMS Veh Class (hourly 

adjusted vmt * I,process rateperdistance) 

Where rate per distance depends on speed bins and MOVES road h;pe

In order to facilitate the calculation pwcess, the air quality module creates a 

database titled EMIS_daily.bin. Each record in this file can be identified by 

network link Ids. Table 2.6 describes the fields in the database EMIS_Daily.bin.

for each of the 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 of VMT by MOVES road type and MOVES source (vehicle) type. As 

a result, the weighting factor varies with MOVES road types and MOVES vehicle 

types. The factor is calculated by using the following equation: 

The weighting factor ~ MOVES_Fmc[road h;pe index4][HPMS vehicle class 

index6][2nd digit of source h;pe]fLMOVES_Frac[road h;pe 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 of calculating daily emissions by pollutant by HPMS vehicle classes. 

The air quality module populates three new fields in the network's line layer: 

Daily_NOx_per _mile, Daily_ VOC_per _mile, and DAILY _PM25_per _mile. These 

fields show the running emissions per mile for each link.

Step 3: 

The air quality module script includes the code to calculate HPMS adjustment 

factors based on HPMS_ VMT_ *.csv. Currently, this block of code is commented 

out in the script since the Indianapolis MPO currently does not use HPMS 

adjustment factors based on previous interagency consultation. Since the model 

table will look for these files, the user needs to create a dummy set of csv files 

(HPMS_ VMT_*.csv) for each of the counties in the following format:

Interagency Consultation Group (ICG) Conference Call Minutes 

For the MOBILE6.2 to MOVES MVEB Replacement Update 

Related to the Indianapolis, Indiana Maintenance Area under the 1997 8-Hour Ozone 

Standard 

ICG Conference Call Date and Time 

• January 18,2012 at lpm Eastern 

ICG Attendees 

• Shawn Seals (IDEM), Gale Ferris (IDEM), Patricia Morris (EPA), Steve Smith 

(INDOT), Laurence Brown (INDOT), LatTy Heil (FHWA), Stephanie Belch (Indy 

MPO), Catherine Schoenherr (Indy MPO), Philip Roth (Indy MPO), Steve 

Cum1ingham (Indy MPO) and Vince Bernardin (BLA) 

ICG Discussion Topics and Conclusions 

I. The question of whether or not non-rulliling emissions should be included in 

MVEBs as we move forward was raised. 

A. It was determined by consensus of the ICG 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 of totals with both running and non-running emissions that 

are included as the baseline for the mobile source margins of safety and the all 

source margin of safety discussions. 

2. The question of using one allilual run, or four seasonal runs was raised. 

A. After discussion of the I CG, the consensus was the one allilualtun was 

reasonable and appropriate for MOVES runs. 

3. For the 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 of safety that was inflated for the purpose of accommodating the 

uncertainties of the transition from 2004 to 2009 Indiana vehicle fleet mix. 

B. After discussion, the consensus of the ICG was that as long as a 15% for 

PM2.5 and NOx mobile source margin of safety did not result in an 

exceedance of the all sources margin of safety, it was reasonable and 

appropriate for inclusion in MVEB Replacement submittal. The subsequent 

spreadsheet mentioned above demonstrated that a 15% mobile source margin 

of safety falls well below the all sources margin of safety 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 of safety for VOC, with a 10% margin of safety for NOx. 

B. After discussion, the consensus of the ICG was that as long as the existing 

12% for VOC and 10% for NOx mobile source margins of safety do not result 

in an exceedance of the all sources margins of safety, it was reasonable and 

appropriate for inclusion in MVEB Replacement submittal. The attached 

spreadsheet demonstrates that a 12% for VOC and 10% for NOx mobile 

source margins of safety fall well below the all sources margins of safety and, 

as such, will be reflected in the Ozone MVEB Replacement submittal. 

C. After further study, Indy MPO requested additional time to conduct a 2035 

MOVES-based emissions projection to confirm that the recommended mobile 

source margins of safety for the Ozone SIP submittal will be adequate farther 

into the future. After the 2035 projection was complete, it was confirmed that 

the recommended mobile source margins of safety for the submittal would be 

adequate.

LEGAL NOTICE OF PUBLIC HEARING 

Motor Vehicle Emission Budgets Replacement Update to the Request for 

Redesignation Petition and Maintenance Plan Under the Annual National Ambient 

Air Quality Standard for Fine Particles for the Central Indiana Nonattainment 

Area 

Note: After December 1, 2012, legal notices for public hearings shall no longer be 

published in newspapers, but will be found on the Indiana Department of 

Environmental Management web site at: http://www.in.gov/idem/5474.htm. 

Notice is hereby given under 40 CFR 51.102 that the Indiana Department of 

Environmental Management (IDEM) is accepting written comment and providing an 

opportunity for public hearing regarding the Motor Vehicle Emission Budget (MVEB) 

replacement update to the Request for Redesignation Petition and Maintenance Plan 

Under the Annual National Ambient Air Quality Standard for Fine Particles for the 

Central Indiana Nonattainment Area. Onroad emissions for the original submittal were 

calculated using the MOBILE6.2 mobile model and are now being replaced with the 

United States Environmental Protection Agency's (U.S. EPA's) recently adopted Motor 

Vehicle Emissions Simulator (MOVES) mobile model. All interested persons are invited 

and will be given reasonable opportunity to express their views concerning the submittal 

of the proposed MVEB replacement update to the Indianapolis, Indiana nonattainment 

area for the annual national ambient air quality standard for fine particles. 

The purpose of this notice is to solicit public comment on Indiana's proposed 

MVEB replacement update. The Indianapolis, Indiana nonattainment area includes 

Hamilton, Hendricks, Johnson, Marion, and Morgan counties. The Indianapolis, Indiana 

area was designated as nonattainment for the annual national ambient air quality standard 

for fine particles and is subject to the requirements of Section 172 of the Clean Air Act 

(CAA). One of the compliance requirements mandated by Section 175A(b) of the CAA, 

is the development of a plan demonstrating that maintenance areas will continue to meet 

the annual fine particles standard for the next ten years, which includes MVEBs for 

onroad sources, beyond the cunent maintenance period. This submittal of the proposed 

MVEB replacement update to the Request for Redesignation Petition and Maintenance 

Plan Under the Annual National Ambient Air Quality Standard for Fine Particles for the 

Central Indiana Nonattaimnent Area that was originally submitted on May 31, 2011, is 

being drafted and submitted consistent with U.S. EPA guidance. Upon completion ofthis 

public notice process, the MOBILE6.2-based to MOVES-based MVEB replacement 

update will be submitted to U.S. EPA for approval into the State Implementation Plan. 

Copies of the draft documents will be available on or before December 5, 2012, to 

any person upon request and at the following locations: 

• Indiana Department of Environmental Management, Office of Air Quality, 

Indiana Government Center North, 100 N011h Senate Avenue, Room N1 003, 

Indianapolis, Indiana
