## Clean AirAct Section 110(1) Demonstration To Support Discontinuation ofthe Vehicle Inspection and Maintenance Program in Clark and Floyd counties, Indiana

Overview The Indiana Department ofEnvironmental Management (IDEM) has prepared a revision to the Redesignation Petition and MaintenancePlanfor Clark and Floyd counties in conjunction with the 8-hourozone standard. This revision is to accommodate the discontinuation ofthe vehicle inspection and maintenanceprogram for Clark and Floyd counties. Section 110(1) ofthe Clean AirAct states that the Administrator (ofthe United States Environmental Protection Agency) shall not approve arevision ofa plan (State Implementation Plan or SIP) ifthe revision would interfere with any applicable requirement concerning attainment orreasonable furtherprogress (ofaNational Ambient Air**Qu~lity** 

### Standard). Therefore, IDEM has also prepared a demonsu.-ation that shows that the discontinuation ofthe vehicle emissions testingpr()gram will not interfere with the applicable requirements ofthe National AmbientAirQuality Standards for 8-hourozone and fine particles.

Indiana also committed to maintain all emission control measures necessaryto ensure continued compliance with the standard following redesignation. The vehicle inspection and maintenanceprogram was firSt initiated in 1984 in 

### accordance with the Clean 

### AirAct (CAA). This program was augmented in 

### 1997 to a fully enhanced vehicleinspection**~d**

ozone State Implementation Plan in 1996. Although the U.S. EPA revoked the I-hourozone standard onJune 15,2005, Clark and Floyd counties were**designat~** 

### nonattainment for the eight-hour ozone standard effectiveJune 15,2004. Therefore, the program is required to be inplace until all applicable CleanAirActrequirements are met. The vehicle inspection and maintenanceprogram is authorized by state statute, 

### Ie 13-17-5, paid forbythe general fund, and implementedthrough roles promulgatedbytheAirPollution Control Boardat 326 lAC.----------------_.

13-1.1. This program tests approximately 7% ofthe registered automobiles in the Greater Louisville Basic Ozone Nonattainment Area and costs the State ofIndiana approximately
one million dollars peryear to operate and maintain. The program yields less than a 1% reduction in total NOx and VOC emissions for the nonattainment area.

On July 1,2003, an amendment to IC 13-17-5 became effective that tenninates Indiana's vehicle inspection and maintenance rule for Clark and Floyd counties afterDecember 31, 2006, and directs the Air Pollution Control Boardto amend 326 lAC 13-1.1 to reflectthis change. IDEM is in the process ofamending the staterule to accommodate the discontinuation ofthe vehicle inspection and maintenance program in Clark and Floyd counties. IDEM has also revised the 8- HourRedesignation Petition and Maintenance Plan for Clark and Floyd counties in orderto move the vehicle inspection and maintenance program from Section 6.2 where it was listed as 

### a measure to remain in place overthe course ofthe maintenanceplan,-to Section 8.0 where it is listed as a contingencymeasure. IDEM has also revised Section 6.0 to clarifythat Indiana in the mid-1990s promulgated rules specific to Clarkand Floyd counties that require RACT for new/existing emission sources ofVOCs lo_eating in these counties.

In orderto supportthe revision to the 8-Hour Redesignation Petition and Maintenance Plan for Clark and Floyd counties, IDEM has prepared a demonstration themeets the requirements of Section 110(1) ofthe Clean AirAct, hereinafterreferred to as the Section 110(1) demonstration. This demonstration is supportedbyphotochemicalmodeling and an emissions analysis,

_ Photochemical modelingshows thatNOx"emissions will increaseby 0.78 tons persUlllJI).erd.ay

### incr~ase by0.79 tons perswnmerday

### and .1.49. tons per winterday. Despite this fact 2007 total emissions are projected to be less than the tota12002 emission levels (base year for PM 2.5), 2003 total emission levels (base year for the ozone maintenance plan), and 2009 total emission levels (deadline formonitoring attainmentunderthe PM 2.5 standard). The 2010 and 2020 total emission levels referenced in the ozone maintenance plan are also projected to be less than the total 2003 emissions levels. Therefore,"the discontinuation ofthe vehicle emissions testing program will not interferewith attainment ofthe 8-hourozone standard in Clark and Floyd counties, orelsewhere within the nonattainment area. Furthennore, this demonstration shows that the discontin1;1ation ofthe vehicle emissions testing program will not interfere with the area's reasonable progress towards attainment oftheNational AmbientAir Quality Standard for fine particles (PM 2.5)
The vehicle inspection and maintenance program was implemented as a volatile organic compound (VOC) emission control measure specificallyin association with the I-hourozone standard (revoked effectiveJune 15,2005). The program does not fail motorvehicles for exceedingtailpipe standards for oxides ofnitrogen (NOx) emissions. However, since VOC and NOx areprecursors for ozone, IDEM's 110(1) demonstration**~sesses** thepotential impact of bothprecursors on future ozone concentrations. "Although the vehicle inspection and maintenanceprogram was not implemented as a control mechanism forparticulate matteror fine particles, IDEM's 110(1) demonstration assesses thepotenlial impact that the discontinuation ofthe programmayhave onthe area's abilityto attain the annual standard for fine particles. However,since VOC is not considered a precursor for fine particles, NOx is the onlyprecursorincluded in the assessment, even though the vehicle inspection and maintenance program does not serve as a NOx control measure.

### Section 110(1) Technical Support Document

Introduction for Photochemical Modeling for Ozone and PM2.5 Assessment
IDEM's Office ofAir Quality conducted photochemical modeling to determine whether the discontinuationofthe vehicle-inspection and maintenance program in Clark and Floyd counties would adversely affect the area's ability to attain or maintain compliance with applicable National Ambient Air Quality Standards. The discontinuation ofthe vehicle inspection and maintenance program does result in the loss ofNOx and VOC emission reductions; and thus could affect ozone and fine particle concentrations. This potential increase 

### in emissions was determined using local travel demand model data and emission factors deriving from MOBILE6. The increased emissions were added to the existing emission profiles for Clark and Floyd counties and were modeled and compared to the previous modeling results that included the vehicle inspection and maintenance program in Clark and Floyd counties. Any difference between the two model runs represents the impact on future year design values for ozone or PM2.5 monitors located in Clark and Floyd counties.


### Emissions Estimation and Photochemical Modeling Methodologies

. IDEM is a memberofthe Midwest**Region~l** Planning()rganization (MRPO), which uses

photochemical modeling to determine emission,control strategies for attainment State ;:.AmplementationPlans{SIPs) for Indiana, Illinois, Michigan, Wisconsin and Ohio. The Lake -,.Michigan AirDirectoi$ Consortium (LADCD) supports the MRPO and supplied emissions, ''''i''meteorological and**~hemistry** files as well as photochemiCal'model source codes used in this analysis. Indiana followed the U.S. EPA guidance in all modeling and attainment demonstration**metho~s** for this analysis.
Emissions Estimation Methodology IDEM's Office ofAir Quality adjusted the emissions in orderto determine the·impact ofthe**disc~ntinuation** ofthe vehicle inspection and maintenance program in Clark and Floyd counties. LADCO provided the 2002 base case**e~issions** and future year, emissions for.2009 as well as the weighting factors'to interpolate 2007.emissions betweenthe 2002 and 2009 emissions. Future year2009 emissions were created to account for economic growth and emission control strategies that will be inplace by 2009 for all emissions sectors. Modeling results show the. downward trend for each modeled year and validates this analysis.
LADCO provided a computer softwarepatchto calculate 2007 emissions for all emissions sectors. The emissions adjustments for 2007 were an estImation ofall emission sectors between the known (2002) and calculated (2009) future emission levels. The weighting factor consists of the fraction of-the number ofyears from eachtime period. The**wei~ting** fadors used for

. determining the 2007 emissions are 0.285 

### (217t1Js ofthe emissions from 2002) for 2002 emissions and 0.714 (517lhs ofthe emissions from 2009) for 2009 emissions. The weighting factors were applied to the D;1otorvehicle, low-level point, area sources (marine-air-rail, nonroad and other) and ammoniaemissions. The weighting fact0!S were not applied to the elevated Point source·

emissions because no significantemission changes are expected to thatparticular source sector between 2007 and 2009. Therefore, 2009 elevated point source emissions were used. Each emission sector file was quality assured to determine specific pollutantemissions in gram- 'moles/day, kilograms/day and tons/day. Once emission adjustments were made, all emissions sectorswere merged to create 2007 emissions.
LADCO has

# a computerprogram that adjusts emissions for a specific county and emission sector. Forthe pUI]Jose ofthis analysis, the**disc~ntinuation** ofthe vehicle inspectionand maintenance program in Clark and Floyd counties only affected mobile emissions; therefore the mobile emissions were the only emission sectoranalyzed. The difference between the total 2007 emissions and the total 2007 emissions with Clark and Floyd counties emissions zeroed-out, representthe mobile emissions for Clark and Floyd counties. Table 1.1 shows the modeled mobile source emissions for Clark and Floyd counties for the years 2002,2007 and 2009. All emissions data include the vehicle inspection and maintenance program in Clark and Floyd counties. The quality assured results ofthese emissions adjustments can be found in Appendix A. Also referenced in Appendix A are the total 2007 emissions, 2007 emissions minus the Clark County emissions and the 2007 emissions minus the Floyd County emissions.

Based'on the MOBILE6 emission modeling conducted to determine the impacton NOx and VOC emissions from the discontinuation ofthe vehicle inspection and maintenance program.in Clark and Floyd counties, for.the year 2007, the increase**i~** NOx emissions was 0.78 tons per summerday ana 0.82 tons ofNOx perwinterday. VOC emissions were calculatedto increase by 0.79 tons per summerday and 1.49 tons perwinterday. This change inthe NOx and VOC emissions was th.en used to determine multipliers in orderto adjustthe mobile inventory in the mode1mg files. The multipliers were for both Clarkand Floyd counties: NOx

- 1.047 for
summerand 

### 1.048 for winter; VOC 

### -1.125 for summer and 

### 1.134 for winter. The emission estimates were calculated for the six wintermonths ofOctober, November, December, January, February and March and the six summermonths ofApril, May, June, July, August and September. The emission adjustments were then made to the 2007 mobile modeling files with

2Clark County NOx and VOC emissions adjusted first and the Floyd County NOx and VOC emissions adjusted second to account for the discontinuation ofthe vehicle inspection and maintenance program in those counties. This created the new 2007 mobile emission files which
were quality assured and pre-processed with the other emission source categories for use in**C~.** 

### . Photochemical Modeling Methodology The Comprehensive Air Quality Model with extensions (CAMx) was the photochemical model used; this model is accepted by the U.S. EPA. The meteorology used was the summer of2002 for ozone and the entire year of2002 for PM2.5. Three separate modeling runs were conducted;
one model run to detennine base year (2002) concentrations, one future year (2007) model run included additional NOx and VOC emissions from the discontinuation ofthe vehicle inspection. and maintenance program (without 11M), and one future year (2007) model run with the NOx and VOC emission reductions associated with the vehicle inspection and maintenance program (with VM). The 2007 ozone and PM2
.5modeled results were post-processed and evaluated using the U.S. EPA's attainment test guidelines. Future year design values were calculated from the modeling runs with and without the vehicle inspection and maintenance program being in place. The impact on the future year design values for ozone and PM2.5 monitors in Clark and Floyd counties was detennined.

. design value for ozone of+0.0001 ppm at the Charlestown ozone monitor. No difference in the future year design value forthe New Albany site orother sites within the nonattainment area was detennined. 

### All design values are projected to be below the standard of0.085 ppm. Table 1.2 lists the modeled results from the ozone attainment test and the difference in future yeardesign values as a result ofthe discontinuation ofthe vehicle inspection and maintenance program for Clark and Floyd counties. Since only the third significant digit is used in computation and the modeled difference for the Charlestown site affects the fourth significant digit, there is virtually
no difference in the modeled design values for any monitoring site. IDEM used the average of three design values (2000-2002, 2001-2003, and 2002-2004) for this assessment. The period of time associated with the average design value encompasses the design value that was used in designating the area nonattainment (2001-2003) and the design value used to support IDEM's redesignation petition for Clark and Floyd counties (2003-2005, 

### with 2003 representing the base year).

Conclusions
iDEM's Office ofAir Quality conducted an. ozone and PM2.5 assessment to determine ifthere would be impacts from**~dditional** 

### mobile source

## voe and NOx emissions as a result ofthe discontinuation ofthe vehicle inspection and maintenance program for Clark and Floyd counties. Photochemical modeling was conducted for the summerof2002 for ozone and the entire year of 2002 for PM2 .5. CAMx is the U.S. EPA accepted photochemical mod'el used in conjunction with emissions and chemistry files obtained from the MRPO. Emission adjustments were made to the 2002/2009

### emission files in orderto create a 2007 emissions profile. The motor vehicle emissions for Clark and Floyd counties were determined and the anticipated increase in NOx and 

## voe emissions were added to the 2007 emissions inventory. Modeling results were used in the U.S. EPA attainment tests for 8-hourozone and annual PM2

. 5 

### to determine ifadditional 

## voe and NOx emissions associated with the discontinuation ofthe vehicle inspection and maintenance program would impactthe ozone and PM2.5 monitors in the

. nonattainment area. Based on the attainment tests, there was an increase of+0.000I ppm for the

future yearozone design value at the Charlestown ozone monitor. Since only the third significant digit is used in computation and the modeled difference for the Charlestown site affects the fourth significant digit (.0001), there is virtually no difference in the modeled design valuesforeither siteinClarkand Floyd counties. The projected design valuefor 2007(.084 ppm) .'is below the**8.-ho~**

A difference of-0.1 ug/m3 ofthe annual future yeardesign values for several monitors within the**no~attainmeilt** 

### area was found, with the difference coming from nitrate concentrations. Thoughthis reflects. a potential benefit, a one-tenth ofa microgram per cubic meter impact is negligible. More importantly; an emissions analysis demonstrates that total NOx emissions for the years 2007 and 2009, with the reductions associated with the vehicle emissions testing program excluded, are less than the total NOx emissions in 2002 (the base year for the standard) when the program was inplace. Therefore, the discontinuation ofthe vehicle inspection and' maintenance program for Clark and Floyd counties will not interfere with the area's ability to achieve reasonable progress towards attainmentofstandard by its assigned deadline (April 5, 2010).

## Clean AirAct Section 110(1) Demonstration To' Support Discontinuation ofthe Vehicle Inspection and Maintenance Program in Clark and Floyd counties, Indiana

Overview The Indiana Depart:ment ofEnvironmental Management (IDEM) has prepared a revision to the Redesignation Petition and Maintenance Plan for Clark and Floyd counties in conjunction with the 8-hourozone standard. This revision is to accommodate the discontinuation ofthe vehicle inspection and maintenance program for Clark and Floyd counties. Section 110(1) ofthe Clean AirAct states that the Administrator (ofthe United States Environmental Protection Agency) shallnot approve a revision ofa plan (State Implementation Plan or SIP) ifthe revision would interfere with any applicable requirement concerning attainment orreasonable further progress (ofa National Ambient Air Quality Standard). Therefore; IDEM has also prepared a demonstration that shows that the discontinuation ofthe vehicle emissions testing program will not interfere with the applicable requirements ofthe National Ambient Air Quality Standards for 8-hourozone and fine particles. " Background IDEM recently submitted an 8-Hour Ozone Redesignation Petition and Maintenance Planfor Clarkand Floyd counties (dated July 2006) to the U.S. EPArequesting thatthese coUntiesbe redesignated to attainment ofthe standard. Clark and Floyd counties, along with the remaining portion ofthe Louisville nonattainment area, have attained the NAAQS standard for ozone. Indiana has performed.an analysis that shows the air quality improvements are due to permanent and enforceable measures and that significantregional NOxreductions following implementation ofPhase II ofthe NOx SIP Call and the Clean Air Interstate Rule will enS'!1fe continued compliance (maintenance) with the standard. Indiana's petition includes a long-term maintenance plan that will be implemented to ensure that the areacontinues to meet the 8-hour standard for ground-level ozone through the year 2020. Indiana also committed to maintain all emission control measures necessary to ensure continued compliance with the standard following redesignation. The vehicle inspection.and maintenance program was one ofthose emission control measures. The vehicle inspection and maintenance program was first initiated in 1984 in accordance with the Clean AirAct (CM). This program was augmented in 1997 to a fully enhanced vehicle inspection and maintenance program and was incorporated within Indiana's I-hour
ozone State Implementatiqn Planin 1996. Although the U.S. EPA revoked the I-hour ozone standard onJune 15, 2005, Clark and Floyd counties were designated nonattainment forthe eight-hour.ozone standard effective June 15,2004. Therefore, the program is required to be



### . in place until all applicable Clean AirActrequirements are met. The vehicle inspection and maintenance program is authorized by state statu,te, IC 13-17-5, paid for by the general fund,'

### ..... .... .

OnJuly 1,2003, an amendmenHo IC 13-17-5 became effective that terminates Indiana's vehicle inspection and

### maint~nance rule for Clark and Floyd counties after December 31 2006, and directs the Air Pollution Control Board to amend 326 lAC 13-1.1 to reflect this change. IDEM is in the pro"Cess ofamending the state rule to accommodate the discontinuation ofthe vehicle inspection and'maintenance program in Clark and.Floyd counties. IDEM has also revised the 8-

. HourRedesignation Petition and Maintenance Plan for Clark and Floyd counties in orderto
move the vehicle inspection and maintenance program from Section 6.2 where it was listed as a measure to remain in place overthe course ofthe maintenance plan, to Section 8.0 where it is listed as a contingency measure. IPEM has also revised Section 6.0 to clarifythat Indianain the mid-1990s promulgated rules specific to**Clar~** and Floyd counties that require RACT for new/existing emission sources ofVOCs locating in these counties. and implemented through rules promulgated by the Air Pollution Control Board at 326 lAC 13-1.1. This programtests approximately 7% ofthe registered automobiles in the Greater Louisville Basic Ozone Nonattainment Area and costs the State ofIndiana approximately
one million dollars per yearto operate and maIntain. The program yields less than a 1% reduction in total NOx and VOC emissions for the nonattainment area.
