Re: MOBILE6.2 to MOVES MVEB 

Replacement Update to the Maintenance 

Plan for the Annual Fine Particles 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 annual 

fine particles standard for Lake and Porter counties, Indiana. The United States 

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

and Maintenance Plan Under the Annual National Ambient Air Quality Standard for Fine 

Particles for the Indiana Portion of the Chicago-Gary-Lake County, /L-IN Nonattainment 

Area submitted by IDEM on May 26, 2011 , with an effective date of February 6, 2012. 

IDEM requests that U.S. EPA process this final submittal for approval into Indiana's State 

Implementation Plan. 

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

update to the maintenance plan for the annual fine particles standard for Lake and Porter 

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

hearing was scheduled for January 23, 2013. No request for a public hearing was 

received and the hearing was cancelled. In addition, IDEM received no 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 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 

annual fine particles maintenance plan. 

Onroad safety margins, established through the interagency consultation process, 

are included for nitrogen oxides (NOx) and fine particulate matter (PM2 5). 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 Lake and Porter 

counties, Indiana, annual fine particles 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 PM2 5 emissions (i.e., all source categories) do not exceed attainment 

year emissions to ensure continued maintenance of the annual fine particles 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 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 annual fine particles standard. If you have any 

questions or need additional information, please contact Scott Deloney, Chief, Air 

Programs Branch, at (317) 233-5694.

Introduction 

On May 26,2011, the Indiana Depmiment ofEnviromnental Management (IDEM) submitted a 

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

Standardfor Fine Particles for the Indiana portion of the Chicago-Gary-Lake County, IL-IN 

nonattaimnent area. The United States Enviromnental Protection Agency (U.S. EPA) subsequently 

approved the Indiana redesignation of Lake and Porter counties, Indiana, to attaimnent for the 

annual standard for fine particles with an effective date of February 6, 2012 (76 FR 76302). 

Onroad emissions for the May 26,2011, 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 redesignation and 

maintenance plan for the Lake and Porter counties, Indiana, annual fine pmiicles standard 

maintenance area that incorporates MOVES-based onroad emissions. 

Emission Inventory 

The tables titled, 2008-Lake and Porter Counties, IN Totals (Tons per Year), 2015-Lake and Pmier 

Counties, IN Totals (Tons per Year), 2020-Lake and Pmier Counties, IN Totals (Tons per Year), 

and 2025-Lake and Porter Counties, IN Totals (Tons per Year), were included in Appendix E of the 

original Redesignation Petition and Maintenance Plan. The consolidated table titled, 2008, 2015, 

2020, and 2025 Lake and Potier Counties, 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 onroad emission 

estimates for nitrogen oxides (NOx) and fine particulate matter (PM25) for the yem·s 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 rule for fine particles, Indiana does not consider mobile source SOz to be a 

significant contributor to fine pmiicles for this maintenance area, as mobile source SOz constitutes 

less than 1.2% of the area's total antluopogenic emissions. As such, S02 emissions are not 

included in the table titled, 2008,2015,2020, and 2025 Lake and Porter Counties, Indiana, AreaAll Anthropogenic Sources in Tons Per Year.

Onroad emission estimates in the table titled, 2008, 2015, 2020, and 2025 Lake and Porter 

Counties, Indiana, Area - All Anthropogenic Sources in Tons Per Year were calculated using 

U.S. EPA's MOVES model-produced emission factors and data extracted from the area's traveldemand 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 MVEBs for the Lake and Pmter counties, 

Indiana, mmual fine patticles standard maintenance 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, nomoad, and point) from the original submittal for 

the years 2008, 2015, 2020, and 2025 were developed before the economic challenges ofthe 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 

2 
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 NOx 

and PM2.5 emissions in the Lake and Pmier counties, Indiana, annual fine particles standard 

maintenance area will continue to decline leading to local reductions between 2008 (base year) 

and 2015 (maintenance plan interim budget year), as well as 2008 (base year) and 2025 

(maintenance plan horizon budget year).

Table 5.1 was included on Page 34 of the original Redesignation Petition and Maintenance Plan 

for the Lake and Pmier counties, Indiana, aruma! fine particles standard maintenance area. Table 

5.1-A (to be considered a replacement ofTable 5.1) has been revised to incorporate 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 including Chicago 

Area emissions in this replacement submittal was not necessary due to U.S. EPA's designation of 

attainment separately for Lake and Pmier counties, Indiana effective February 6, 2012.

consultation process, it was determined that substituting the previous interim budget year of 2015 

with a revised interim budget year of2015 was both reasonable and appropriate for transportation 

conformity demonstrations moving forward.

Tlu·ough the interagency consultation process, it was determined that a revised maintenance plan 

interim budget year of2015 and a horizon budget year of2025, would be appropriate. The 

interagency consultation group approved onroad margins of safety of fifteen percent ( 15%) for 

both NOx and PM2.5 onroad 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 onroad NOx and PMz.s emissions in the Lake and Porter counties, 

Indiana, annual fine particles standard maintenance area will continue to decline leading to local 

reductions between 2008 (base year) and 2015 (revised maintenance plan interim budget year), as 

well as 2008 (base year) and 2025 (maintenance plan horizon budget year). 

4 
Fmihermore, when compared to the overall safety margin as defined in the Code of Federal 

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 of an onroad safety margin 

to mobile sources, emissions will continue to remain well below the overall safety margin for all 

sources as detailed in the table titled, 2008, 2015, 2020, and 2025 Lake and Porter Counties, 

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 year 

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

particles standard. 

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 Indiana pmiion of the Chicago-Gary-Lake County, IL-IN nonattainment 

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 conformity determinations. 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 NO, and PM2.5, established through the 

interagency consultation process, are included in order to account for the wide mmy of 

assumptions that are factored into the calculation process. MVEBs are also constrained to ensure 

that total NOx and PM2.s emissions (i.e., all source categories) do not exceed attainment year 

(2008) emissions to ensure continued maintenance of the mmual fine pmiicles standard. With the 

addition of MOVES-based onroad safety margins applied to mobile sources, the Lake and Pmier 

counties, Indiana, aruma] fine particles standard maintenance area will continue to remain well 

below the overall safety margins for all sources into the future. As such, the mmual fine patiicles 

maintenance plan for Lake and Pmier counties, Indiana, continues to meet all applicable CAA 

requirements.

Overview: 

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 MOVES201 Oa 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 (INDOT). 

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. 
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 LDT4). 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 MOVES201 0 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 MOVES2010 for Emission Inventory 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.
