Dear Ms. Hedman: 

Re: Request to Parallel Process the Draft 

MOBILE6.2 to MOVES MVEB 

Replacement Update to the Maintenance 

Plan for the 1997 8-Hour Ozone Standard 

for Lake and Porter Counties, Indiana 

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 to the maintenance plan for the 1997 8-

hour ozone standard for Lake and Porter counties, Indiana. The United States 

Environmental Protection Agency (U.S. EPA) approved the Request for Redesignation 

and Maintenance Plan for Ozone Attainment in the 8-Hour Ozone Nonattainment Area, 

Lake and Porter Counties, Indiana submitted by IDEM on June, 5, 2009, with an effective 

date of May 11 , 2010. IDEM requests that U.S. EPA parallel process this draft MVEB 

replacement 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 maintenance plan for the 1997 8-hour ozone standard for Lake and Porter 

counties, Indiana, if a public hearing request is received by January 14, 2012. A hearing 

has been scheduled for January 23, 2013. If a request for a public hearing is not 

received by January 14, 2012, the hearing will be cancelled. IDEM is providing a 36 day 

comment period on this update, with the public comment period ending on January 25, 

2013. The final submittal of the MVEB update for the maintenance plan for the 1997 8-

hour ozone standard for Lake and Porter counties, Indiana 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 Lake and Porter counties, 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 1997 

8-hour 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 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 Lake and Porter 

counties, Indiana, ozone 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. 

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, Chief of U.S. EPA Region 5's Control Strategies Section. 

IDEM respectfully requests that U.S. EPA proceed with preliminary 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 Lake and Porter 

counties, 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.

Introduction 

On June 5, 2009, the Indiana Department of Environmental Management (IDEM) submitted a 

Request for Redesignation and Maintenance Plan for Ozone Attainment in the 8-Hour Ozone 

Nonallainment Area, Lake and Porter Counties, Indiana. The United States Environmental 

Protection Agency (U.S. EPA) subsequently approved the Indiana redesignation of Lake and Porter 

counties, Indiana, to attainment for the 1997 8-hour ozone standard on May 11,2010 (75 FR 

26113). Onroad emissions for the June 5, 2009, 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. Therefq~lJ:,IDEM is providing this 

MOBILE6.2 to MOVES replacement update to the previously_s!i!imlhed 1997 8-hour ozone 

maintenance plan for the Lake and Porter counties, Indiana,,,g~~~~''inaintenance area that

This report is being written to document the input parameters for a set of MOVES201 Oa 

runs for the Lake and Porter Counties 8-hour Ozone Maintenance Area and the Lake 

and Porter Counties PM 2.5 non-attainment area. This report contains a discussion on 

the intended input settings used in MOVES201 Oa and the development of the input 

datasets. These MOVES2010a runs are intended to develop a default set of emission 

rates that can be used for conformity determination and is part of a statewide effort being 

conducted by the Indiana Department of Transportation (IN DOT). 

Throughout this report references are made to MOVES 201 Oa codes for two types of 

data. The values for the source type codes are shown in Table 1. The values for the 

road type codes are shown in Table 2. MOVES2010a input settings and assumptions for 

this effort are shown in Appendix A.

The vehicle age distributions for MOVES source types 21, 31, and 32 (cars, passenger 

trucks, and light commercial vehicles respectively) were developed through an analysis 

of Indiana's 2009 vehicle registration data. The analysis was performed by Eastern 

Research Group (ERG) under contract to the Lake Michigan Air Directors Consortium 

(LADCO). ERG was provided with vehicle identification numbers (VIN) for vehicles in 

Indiana. 

I 
There were approximately 6.37 million VINs in the statewide data set. Out of these, 

approximately 1.3 million returned errors. Of these, approximately 200,000 errors were 

deemed non-critical. This means that the model year and vehicle type assigned to the 

records were most likely correct despite there being an error in the VIN decoding. These 

records were included in ERG's analysis. The remaining errors were considered critical 

enough to call into question the accuracy of the model year and vehicle types. These 

critical errors were excluded from ERG's analysis. 

In all, approximately 5.2 million VINs from around the state were used in the analysis. 

Each VIN was associated to a specific county. ERG then developed age distributions for 

each county in the state along with seven combination areas comprised of two or more 

counties each. Additional information on the methodology used to develop the vehicle 

age distributions can be found in a May 28, 2010 report written by ERG for LADCO titled 

MOBILE6 and MOVES Registration Distribution Calculations for Indiana Registration 

Data. Each set of age distributions was provided in both MOBILE6 and MOVES formats. 

The MOVES formatted data will be used for these MOVES2010a runs. 

Due to limitations in ERG's VIN decoder, it was not possible to develop vehicle age 

distributions for any source types other than 21, 31, and 32 from the vehicle registration 

data. For all other source types, MOVES201 Oa default vehicle age distributions specific 

to each source types were used. This includes motorcycles and all heavy vehicles. 

Vehicle age distributions for all source types were kept constant for all future years. The 

vehicle age distributions for Lake and Porter Counties as a combined area are shown in 

Appendix B of this report. 

Vehicle Population: 

The vehicle populations for source types 21, 31, and 32 were developed directly from 

the vehicle registration data. All valid records that were identified from the vehicle 

registration data set were used to determine the number of vehicles for each of these 

three source types. The VIN decoded data provided to INDOT contained vehicle types 

according to MOBILE6.2 vehicle categories. There is a direct correlation between 

MOVES source type 21 (cars) and the MOBILE6.2 vehicle type LDV. All valid LDV 

records (those records not excluded from the vehicle age distribution analysis due to 

errors as was described in the section on Vehicle Age Distribution in this report) were 

counted in the vehicle population. 

There is not a direct correlation between MOVES source types 31 (passenger trucks) 

and 32 (light commercial vehicles) and the MOBILE6.2 light truck vehicle types (LDT1, 

LDT2, LDT3, and LOT 4). All valid records from the vehicle registration data set for 

MOBILE6.2 light duty trucks were counted in the vehicle populations. The light duty 

trucks were distributed between MOVES source types 31 and 32 as per the 

Environmental Protection Agency's (EPA) guidance documented in Table A.1 of the 

appendix of the Technical Guidance on the Use of MOVES2010 for Emission Inventory 

Preparation in State Implementation Plans and Transportation Conformity. The guidance 

provides two sets of factors for distributing MOBILE6.2 light trucks between MOVES 

source types 31 and 32. These are based on fuel type and are shown in Table 3. 

2 
Table 3: Distribution of MOBILES 2 Light Duty Trucks into MOVES Source Types 

Source Types 

Fuel 31 32 

Gas 78% 22% 

Diesel 42% 58% 

As per ERG's assumption documented in MOBILE6 and MOVES Registration 

Distribution Calculations for Indiana Registration Data, all light duty trucks that did not 

have a fuel type identified were counted as diesel trucks. This was to prevent an 

underestimation of diesel trucks and their related emissions. 

Since only valid records from the vehicle registration data were used to calculate vehicle 

populations for source types 21, 31, and 32, it is reasonable to assume that some of the 

erroneous records that were discarded from the analysis actually belonged to these 

source types. The nature of these errors is not that the vehicle does not exist. Rather, it 

is that the vehicle could not be properly identified with any sense of certainty. It was 

therefore necessary to adjust the vehicle populations calculated from vehicle registration 

data to compensate for these discarded records. Based on an analysis of the error rate 

reported by ERG, vehicle populations for source types 21, 31, and 32 were increased by 

5.8 percent. 

Vehicle populations were not able to be developed directly from the vehicle registration 

data for some source types. This was due to the limitations in the VIN decoder used by 

ERG to process the vehicle registration data. Vehicle populations for all other source 

types (motorcycles and heavy vehicles) were derived by applying the Mileage 

Accumulation Rate (MAR) method documented in EPA's Technical Guidance on the Use 

of MOVES201 0 for Emission lnventorv Preparation in State Implementation Plans and 

Transportation Conformity, Section 3.3 Source Type Population. 

The default MARs were extracted from MOVES by running MOVES for a single pollutant 

and a single year for all vehicles, fuels, months, days, and hours. The activity output was 

set to report both distance and population. A ratio of population to vehicle-miles-traveled 

(VMT) was calculated from these outputs. The ratios were calculated for each source 

type. 

The Northwestern Indiana Regional Planning Commission (NIRPC), which is the 

metropolitan planning organization (MPO) for Lake and Porter Counties, provided VMT 

by MOVES road types extracted from their travel demand model's base year. Since the 

default MARs in MOVES vary by year (but not by location), the MOVES run that was 

executed to extract the MARs was run for a year consistent with the travel demand 

model's base year. This resulted in MARs that could be applied directly to the validated 

VMTs reported by the travel demand model. The travel demand model VMTs were 

converted into annual VMT and distributed by vehicle types using statewide default VMT 

distribution factors documented in this report in the section on Default VMT Distributions. 

The MARs were then applied to the annual vehicle type VMTs. The result was an 

estimated vehicle population for each source type for the travel demand model's base 

year. Since the vehicle populations for source types 21, 31, and 32 were developed 

directly from the vehicle registration data, the population estimates derived for those 

3 
source types using the MAR method were discarded and the observed data were used 

instead. 

Future year vehicle populations were developed base on socioeconomic growth rates for 

the maintenance area. The MPO provided base year and horizon year population and 

employment data for the area. Annual growth rates were calculated for population 

growth and employment growth individually. Population growth rates were then used to 

grow the light vehicle populations (source types 11, 21, 31, and 32). Employment growth 

rates were used to grow the heavy vehicle populations (source types 41, 42, 43, 51, 52, 

53, 54, 61, and 62). Vehicle populations were calculated for every year from 2008 to 

2040. These vehicle populations for Lake and Porter Counties as a combined area are 

shown in Appendix C. 

Meteorological Data: 

The default set of hourly temperatures and hourly relative humidity was developed using 

EPA's data converters for changing MOBILE6.2 minimum I maximum temperatures and 

absolute humidity to the MOVES equivalent formats. The values for the MOBILE6.2 

inputs were taken from the Air Quality Conformity Determination Between the 2040 

Regional Transportation Plan, the Fiscal Year 2012 to 2015 Transportation Improvement 

Program, and the Indiana State Implementation Plan for Air Quality, Appendix E, 

developed by NIRPC in June, 2011. 

Meteorological data reflect average annual conditions for the PM 2.5 runs. The 

MOBILE6.2 meteorological input data for each of the twelve months of the years were 

averaged together to create average annual temperatures and humidity. These were 

then passed through the data converters. The data reflect summer conditions for ozone 

using MOBILE6.2 inputs for July. The MOVES formatted meteorological data for Lake 

and Porter Counties as a combined area are presented in Appendix D of this report. 

Default VMT Distributions: 

As part of this effort, INDOT developed a default set of VMT distribution factors by 

Highway Performance Monitoring System (HPMS) vehicle type and by MOVES road 

type. These distribution factors were developed by analyzing four consecutive years of 

continuous traffic count data ending in 2010 for twenty permanent traffic count stations 

throughout Indiana. The stations were selected to provide a spread of locations 

corresponding to each of the four MOVES road types. Furthermore, these stations were 

selected from among sites that were concentrated in nonattainment and maintenance 

areas. In some cases, data from the requested site were either partially or completely 

unavailable. An inventory of the sites used to develop the distributions is shown in Table 

4. 

The vehicle counts reported at each station were provided by vehicle class. These were 

aggregated into the six basic HPMS vehicle types: motorcycle, passenger car, light 

truck, bus, single-unit heavy truck, and combination heavy truck. The distribution of VMT 

by vehicle type was calculated for each road type by taking each vehicle type's 

percentage of total traffic. These default statewide factors are shown in Appendix E.

Default Hourly Distributions: 

The same set of twenty permanent traffic count locations discussed in the section on 

Default VMT Distributions was analyzed to develop a set of hourly distribution factors. 

These factors were calculated by road type, by HPMS vehicle type. Hourly factors were 

only calculated for the average weekday. The hourly distribution pattern for each traffic 

count location was reviewed. Any data that appeared to reflect either an error in the data 

or an outlier of behavior were removed to prevent bias in the data. The following data 

were excluded from the analysis: 

• Bus data from count stations 0105 and 0603 were excluded due to abnormal 

midnight peaks in the data; 

• An abnormal relationship between passenger cars and light duty trucks at count 

station 4500 prompted the exclusion of all data from this location due to 

questions of reliability; 

• Peak spreading behavior observed at count station 4000 from traffic related to 

Chicago was considered to be too unique to be included in a default statewide 

data set; and, 

• Combination truck traffic from station 3200 was excluded due to too much 

overnight traffic when compared to other vehicles and other stations. 

5 
Furthermore, traffic patterns reported by those count stations corresponding to road type 

3 (3000, 4500, 0105, 0201, 0502, 0602, and 0603) had a tendency to over represent 

long distance travel. This was most likely the result of statewide permanent count 

stations focusing primarily on higher order facilities. Rural collectors and local streets are 

less likely to reflect long distance travel. The hourly distributions for road type 3 (rural 

unrestricted access) were adjusted to better account for traffic behavior on lower order 

facilities in rural areas. A sample of traffic count data from Morgan County, IN was used 

to introduce more local traffic behavior in the road type 3 hourly distributions. An analysis 

of the Morgan County data showed a pattern more consistent with AM and PM peaking 

characteristics reflecting local commuting traffic on collectors and local streets for 

passenger cars and light duty trucks. The Morgan County data for passenger cars and 

light duty trucks on collectors and local streets were weighted and added to the road 

type 3 data set. This analysis assumed that rural collectors and local streets accounted 

for 20 percent of all VMT for road type 3. 

The statewide default hourly distribution factors are presented in Appendix F. 

Default Daily and Monthly Distributions: 

Default daily and monthly distribution factors were calculated from IN DOT's official count 

adjustment factors which are more commonly used to develop AADT from raw traffic 

counts. These factors are based on the set of daily traffic counts collected from all 

permanent count stations throughout the state. The daily distribution factors determine 

what percentage of VMT is occurring on weekdays and what percentage is occurring on 

weekends. The monthly distribution factors determine what percentage of annual VMT is 

occurring in each month of the year. The statewide default daily distribution factors are 

shown in Appendix G. The statewide default monthly distribution factors are shown in 

Appendix H. 

Ramp Fractions: 

The ramp fractions represent the percentage of vehicle-hours-traveled (VHT} for road 

types 2 (rural restricted access) and 4 (urban restricted access) occurring on the ramps 

associated with those road types. These fractions were calculated based on the 

percentage of VHT occurring on ramps reported by the base year travel demand model. 

These ramp fractions are reported in Appendix I.

ICG Discussion Topics and Conclusions 

I. For the Ozone MVEB Replacement submittal, various mobile source margins of 

safety were discussed. 

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

mobile source margin of safety for VOC and NOx emissions does not result in 

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

appropriate for inclusion in MVEB replacement submittal. 

2. For the PMz.s MVEB Replacement submittal, various mobile source margins of 

safety were discussed. 

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

mobile source margin of safety for NOx and PM2.5 emissions does not result in 

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

appropriate for inclusion in MVEB replacement submittal.
