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 Under the 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 of the 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 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

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 onroad 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.

Onroad Emissions MOBILE6.2 to

MOVES Replacement Submittal

For the Indianapolis, Indiana

Maintenance Area Under the 1997

8-Hour Ozone Standard
This page intentionally left blanl,
Introduction

On March 26, 2007, the Indiana Depaliment of Enviromnental Management (IDEM) submitted a

Requestfor Redesignation and Maintenance Plan for Ozone Attainment in the 8-How' Ozone

Nonattainment Area, Cenh'al Indiana Area. 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 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 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 over the 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 of assumptions that are factored into the calculation process. Since assumptions

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

impact 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 VOC emissions in the Central Indiana Area will continue to decline leading to local

reductions between 2005 (base year) and 2020 (maintenance plan horizon).

Tl"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 of Table 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.

VOC 64.32 25.47

Through the interagency consultation process, it was determined that a maintenance plan horizon

year budget of 2020, 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 of this 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 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 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 of either NOx or YOC, thereby ensuring continued maintenance of the 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 of the MOVES model in future transpOliation conformity

3
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 NOx

and VOCs, established through the interagency consultation process, are included in order to

account for the wide array of assumptions 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 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 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 of ozone and PM,.5 emissions within the TDM

post-processor, MOVES201Oa 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 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 next full update of the Indianapolis LongRange Transportation Plan (LRTP) 01' evelY five years at a 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 of the model (Le., 2002, 2005, 2006, and 2008) will be calculated off-model by

the Indianapolis MPO. Figure 1.1 illush'ates why each of the ail' quality analysis

years were chosen. Itshould be noted that year 2035 is the CUl'l'ent LRTP horizon

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

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

conformity determination.

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

refueling process and PM1.5 tirewear process. While these calculation errors internal to MOVES arc believed

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

of the differences arc unknown 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 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-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 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

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 popuiation 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 INDOT 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 non attainment 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 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 ail' quality

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

stream script. It calls 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 input files 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 ofIndiana 2-3

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 adjustment factors based on the ratio of

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

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

previous interagency consultation discussions, HPMS adjustment factors are not

currently used by tile Indianapolis MPO and as such, tllese factors are set to 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 network links.

• Caiculate_Runnin~Emissions: TItis macro calculates the daily rwlning emissions

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

• Summaty: 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 2.1 lists each of these

combinations and their assigned HPMS functional classification code.

State ofIndiana 2-5
Table 2.1 HPMS Functional Class Codes Assigned Based on Area

The assignment of HPMS 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 = emission from rate per vehicle by

pollutant + emission fl'Om rate per profile by pollutant

emission fl'Om rate per vehicle by pollutant = Ihoul'IsourceIprocess

rateperuehicle* vehicle population

emission fl'Om rate per pl'Ofile by pollutaHt = IhourIsource rateperprofile*

vehicle population

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[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
Stnte ofIndinnn

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

= 4for urban restricted access

If HPMS = 1 or (HPMS= 2 and facility type =2) then MOVES3YPE = 2

where MOVES_TYPE = 2for rural restricted 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 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,

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 of each time period.

Table 2.4 Hours Within Each Time Period

State of1l1dimw

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 skim is 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 InrazonalVMTfor centroid connector i= IntrazonalVMT at TAZ * share

ofassigned VMT ali

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

at each centroid connectors oftile TAZ)

2-9
The calculated inh'azonal 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.

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_ADIJACTfor counn) c and HPMS functional class h = (HPMS VMT

for c and h)/(sum ofmodel 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 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 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.

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

of the network link:

Daily rUllI1ing emission by pollutant = I,llOurI,HPMS Veh Class (hourly

adjusted vmt * I,process rateperdistance)

Where rate pel' distance depends on speed bins and MOVES road n)pe

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

The running emission is calculated

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, tile 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 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 of calculating daily emissions by pollutant by 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.

The air quality module stores the emission summaries in two separate files:

1. Emission_by_HPMS_Functinal_Class_by_County.csv

2. Emission_by_County.csv

The first file reports the daily rmming emissions by HPMS functional class and

County. The second file reports the daily rmming emissions by County. Both of

the files report daily non-rurming emissions for the region. Sample output is

ICG Discussion Topics and Conclnsions

I. The question of whether 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 of using 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. 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 ofsafety that was inflated for the purpose of accommodating 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 of safety did not result in an

exceedance ofthe all sources margin ofsafety, it was reasonable and

appropriate for inclusion in MVEB Replacement submittal. The subsequent

spreadsheet mentioned 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 of the 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

spreadsheet demonstrates 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 that the recommended mobile

source margins ofsafety 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 ofsafety for the submittal would be

adequate.
