REQUEST FOR REDESIGNATIONAND

MAINTENANCE PLAN FOR OZONE ATTAINMENT

IN THE 8-HOUR OZONE BASIC

NONATTAINMENT AREA

CLARK AND FLOYD COUNTIES, INDIANA

1.0 INTRODUCTION

This document supports Indiana's request that Clark and Floyd Counties, which are part ofthe

Louisville basic ozone nonattainment area, be redesignated from nonattainment to attainment of

the 8-hour ozone standard. In addition, the State ofKentucky also intends to submit a request

for the Kentucky portion Qfthe Louisville basic ozo~e nonattainrnent area to be redesignated

from nonattainment to attainment ofthe 8-hour ozone" standard. The Louisville area has recorded

three years of co~plete, quality assured ambient air quality monitoring data for 2003 - 2005

demonstrating attainment with the 8-"hour standard.

Section 1"07 ofthe Clean Air Act (CAA) establishes specific requirementsl<> beme.t'inorderfor '

Can. area t<,>be considered for redesigriation including:

fa) •A detennination that the area has attain~d the i8-hour ozone standard~ "

(b) Anapproved State ImplementatiollPlail(SIP) for the area wider Seqtlon lrO(k).

(c) A determination that the improvement in air quality is due to permarient and

enforceable reductions in emissions resulting from implementation ofthe SIP and

other federal requirements.

(d)" A fully approved maintenance plan under Section 175{A).

(e) A determination that all Section 110 and Part D requirements have beenmet.

This document addresses each ofthose requirements. It also provides additional information to

support continued compliance with the 8-hour ozone standard.

1.1 Background

The Clean Air Act Amendments of 1990 (CAAA) required areas failing to meet the National

Ambient Air Quality Standard (NAAQS) for ozone to develop SIPs to expeditiously attain and

maintain the standard. In 1997 the United States Environmental Protection Agency (U.S. EPA)

revised the air quality standards for ozone replacing the"1979 I-hour standard with an 8-hour

ozone standard set at 0.08 parts per million (ppm). The standard was challenged legally and

upheld by the U.S. Supreme Court in February of2001. The U.S. EPA designated areas under

the 8-hour ozone standard on April 15, 2004 as attainment, nonattainment, or unclassifiable.

I
Historically two (2) monitors have been operated by the IDEM's Office ofAir Quality in Clark

and Floyd Counties. In Clark County, the Charlestown monitor (Airs ID 18-019-0003) has

operated continuously since prior to 1980. In Floyd County, theNew Albany monitor (Airs ID

18-043-1004) has been operated continuously since 1995. On April 15, 2004, U.S. EPA

designated Clark and Floyd Counties Basic nonattainment and subject to the new 8-hour ozone .

requirements, including development ofa plan to reduce volatile organic compound (VOC) and

oxides of nitrogen (NOl{) emissions and a demonstration that the area will meet the 8-hour ozone

standard for ozone by June 15,2009.

1.2 Geographical Description

FolloWing is a briefdescription ofthe Louisville basic nonattainment area.

Jefferson, Bullitt and Oldham Counties located in north central Kentucky and Clark and Floyd

Counties located in southeastern Indiana are part ofthe Louisville metropolitan statistical area.

This area is surrounded by the Kentucky counties of Hardin, Henry, Nelson, Shelby, Spencer, and

Trimble and the Indiana counties ofHarrison, Jefferson, Scott, and Washington. The Ohio River

·flows along the border between Kentucky and Indiana and the area lies within the Ohio River

Valley. The Louisville Basic Nonattainment Area is shown in Figure 3.1 .

.• lhe Indiana Department ofEnvironmental Management (IDEM), on behalfofthe Stateof

Indiana, isrequesting redesignation for Clark and FloydCoiintiesin Indiana. TheAirPQllution·

Control District ofJefferson County (APCD) is rel)ponsiblefor JeffersonCounty.(Lpwsville) in

north central I<.entucky. The Kentucky Department ofEnvironmental ProtectiQIl(KDEP}is

responsible for Bullitt and Oldham Counties in Kentucky. the KentuckyDepartment of

Environmental Protection is reque$ting redesignation of Kentucky's portion ofthe

nonattainment area, including Bullitt, Oldham and Jefferson Counties, from U.S. EPA Region

IV, concurrently.

1.3 Status ofAir Quality

Ozone monitoring data for the most recent three (3) years, 2003 through 2005, demonstrates that

air quality has met the NAAQS for ozone in this Basic nonattainment area. This fact,

accompanied by the permanent and enforcea~le reductions in emission levels discussed in

Section 4.0, justifies a redesignation to· attainment for the subject area based on Section 107(d)

.(3) (E) ofthe CAAA.

..
2.0 REQUIREMENTS FOR REDESIGNATION

2.1 General

Section 110 and Part. D ofthe CAAA lists the requirements that must be metby nonattainment

areas prior to consideration for redesignation to attainment. In addition, U.S. EPA has published

detailed guidance in a document entitled ··Proceduresfor Processing Requests to Redesignate

Areas to Attainment", issued September 4. 1992. to Regional Air Directors. This document is

hereafter referred to as "Redesignation Guidance". This Request for Redesignation and

Maintenance Plan is based on the Redesignation Guidance, supplemented with additional

guidance received from staffofthe Regulatory Development Section of U.S: EPA Region V.

3.0 OZONE MONITORING

3.1 Ozone Monitoring Network

There are two (2) monitors measuring ozone concentrations in Clark and Floyd·Counties. These

monitors are currently operated by IDEM's Office ofAir Quality (OAQ). A listing ofthe

existing monitors' four (4) highest readings from 2003 through 2005 is shown in Table 3.1 and

was retrieved from the U~S. EPA's Air Quality System (AQS). The locations ofthe monitoring

sites for Clark and Floyd Counties.are shown on Figure 3.1.

3.2 Ambient Ozone Monitoring Data

The following infonnation is taken from U.S. EPA's "Guideline on Data Handling Conventions

for the 8-hour Ozone National Ambient Air Quality Standard (NAAQS),"U.S. EPA-454/R-98-

017, December 1998.

Three (3) complete years ofozone monitoring data are required to demonstrate attainment at a

monitoring site. The 8-hour primary and secondary ozone ambient air quality standards are met

at an ambient air quality monitoring site when the three (3) year average ofthe annual fourthhighest daily maximum 8-hour average ozone concentration is less than or equal to 0.08 ppm.

When this occurs, the site is said to be in attainment. Three (3) significant digits must be earned

in the computations. Because the third decimal digit, in ppm, is rounded, 0.084 ppm is the

largest concentration that is less than, or equal to 0.08 ppm. Therefore, for the purposes ofthis

request, the 8-hour.standard is considered to be 0.085 ppm. Values below 0.085 ppm meet the

s~dard, values equal to or greater than 0.085 ppm exceed the standard. These data handling

procedures are applied on an individual basis at each monitor in the area. An area is in

compliance with the 8-hour ozone NAAQS if, and only if, every monitoring site in the area meets

the NAAQS. An· individual site's three (3) year average ofthe annual fourth· highest daily

maximum.8-hour average.ozone concentration is also called: the site's design value.. The air

quality design value fodheareais the highest design.value among aU monitoringcsites in the ar~fi: . . '..

···lislot'the sites' desIgn va11:les it in Appendix A. The area's design value hastiended dowpward·

as emissions have declined·due to such programs as the Acid Rain program and cleaner

automobiles and fuels both regionally and locally. U.S. EPA's rule to control nitrogen oxides

from specific source categories (40 CFR Parts 51, 72, 75 and 96, published on October 17, 1998

and referred to as the "NOxSIP Call") has significantly reduced emissions from large electric

generating units (EGUs),industrial boilers, and cement lOIns. Indiana's NOxRule was adopted

on June 6, 2001 (326 lAC 10-3 and 10-4). An analysis ofmeteorological conditions and

monitoring values is in Section 7.0 and supports the conclusion that attainment ofthe standard as

of2005 is not the result ofunusually favorable meteorologi~al conditions. It is expected that this

downward trend will continue as the above·programs continue and the U.S"EPA Clean Air

Interstate Rule is implemented.

3.3' Quality Assurance

IDEM has quality assured all data shown in Appendix A. in accordance with 40 CFR 58.10 and

the Indiana Quality Assurance Manual. IDEM has recorded the data in the AQS database and,

thus, they are available to the public.

8
3.4 Continued Monitoring

Indiana commits to continue monitoring ozone levels at or near the sites indicated in Table 3.1

and Appendix A. IDEM will consult with U.S. EPA Region V staffprior to making changes to

the existing monitoring network, ·should changes be necessary in the future. IDEM will continue

to quality assure the monitoring data to meet the requirements of40 CFR 58. Connection to a

central station and updates to the IDEM websiteI will provide real time availability ofthe data

and knowledge ofany exceedances. IDEM will enter all data into AQS on a timely basis in

accordance with federal guidelines.

4.0 EMISSION INVENTORY

Clark and Floyd Counties are part ofthe Louisville metropolitan area but account for a relatively

small portion ofthe overall emissions inventory. The impact ofthe NOx SIP call on monitor

values in Clark and Floyd Counties demonstrate the area is affected by transport. Thert?fore,

regional emission reductions affect ozone levels in Clark and Floyd Countie~ far more so than

emission reductions within the counties themselves. Graphs 4.2 and 4.7 demonstrate .the most

relevant regional reduction in NOx that is attributable to the lowered ozone cqncentrations in

(Jll:lrkand Floyd C<;>unties. B~causeof the significance ofregional emissionsr~duetions,.Section

4:00summarizes both regional and local emissions information. . 0 •

U.S.EPA's Rede~ignation Gllldance requires the submittal ofa comprehensiv~inventory of

ozone prt?cursor emissions (VOC and NOx) representative oftheyear when the ·area·achieves"O .

attainment ofthe ozone air quality standard;.Indiarla must also demonstrate tHat the o improvement

in air quality between the year that vio.lations occurred and the year that attainment was achieved

is based on permanent and enforceable emtssion reductions. Other emissions inventory related

requirements include a pI:ojection ofthe emission inventory to a year at least ten (l0) years

following redesignation, a demonstration that the projected level ofemissions is sufficient to

maintain the ozone standard, and a commitment t.o provide future updates ofthe inventory to

enable tracking ofemission levels during the ten (lO) year maintenance. period.

The following subsections address each ofthese requirements.

4.1 Emission Trends·

Graphs 4.1 and 4.2 show the trend in point source emissions ofVOC and NOx respectively that

generally correspond to the years ofmonitored values referenced in this petition. The point

source data are taken from Indiana's ~ual emissions reporting program.

EGUSources

Graph 4.3 depicts the trends in statewide NOxemissions from EGUs. While ozone and its

precursors are transported into this region from outside the area, this information does provide

some indication ofthe' impact that Indiana sources may have on the nonattainment area. The

emissions are decreasing substantially in response to national programs affecting all EGUs such

as the Acid Rain program and the NOxSIP Call. Other se~tors ofthe inventory also impact

ozone formation, but large regional sources such as EGUs have a substantial impac~ on the

formation ofozone. .

These data were taken from U.S. EPA's Clean Air Markets database2

• Data are available sooner

for these units than other point sources in the inventory because ofthe NOxSIP Call budget and

trading requiremen~s. Information from 2003 is significant because some EGUs started operation

oftheir NOxSIP Call controls in order to generate Early Reduction Credits ror their future year

NOx'budgets. The first season ofthe SIP CaU budget period began May 31, 2004.

As part ofthe NOxSIP Call, the states were required to adopt into their rules a budget for all

large EGUs. Indiana's budget is referenced in ~26 lAC 10-4. The budget represents a statewide

cap on NOx emission~. Although each unit is allocated emissions based upon historic heatiinput~ i

4.2 Base Year Inventory

IDEM prepared a comprehensive inventory for Clark and Floyd Counties, including Area,

Mobile, and Point sources for precursors ofozone (volatile organic compounds and nitrogen

oxides) for base year 2003.

• Area source emissions for the 1996 and 1999 inventories were generated by U.S. EPA and

are part ofthe National Emissions Inventory (NEI). The 2003 area sources were projected

from the Indiana 2002 periodic inventory submitted to U.S. EPA. These projections were

derived by applying growth factors developed under contract for LADCO modeling.

• .Mobile source emissions for 1996 and 1999 were generated by U.S. EPA and are part ofthe

National Emissions Inventory (NEI). The 2003 mobile source emissions were calculated from

MOBILE6 produced emission factors.

• Point source infonnation for 1996 and 1999 was compiled from IDEM's 1996

and 1999 annual emissions statement database. Point source information for the 2003

analysis was compiled from IDEM's 2003 annual emissions statement database and the 2Q03

U.S. EPA Air Markets acid rain database3 .

allocation for agricultural sources was also updated. One ofthe contractors also estimated

emissions for two (2) non-road categories not included in U.S. EPA's Non-road model.

Appendix B contains data tables and graphs ofall these emissions.

4.3 Emission Projections

In consultation with the U.S. EPA and other stakeholders, IDEM selected the year 2020 as the

maintenance year for this redesignation request. This document contains projected emission

inventories for 2011 and 2020. . .

14
IDEM performed emission projections'for Clark and Floyd Counties using the following'

approaches:

• Mobile source emission projections are based on the U.S. EPA MOBILE6 model. The

'analysis is described in more detail in Section 5.0. All projections were made in accordance

with "Procedures for Preparing Emissions Projections"; U.S. EPA-45/4-91-019.

• Mobile source emission projections for 2011 and 2020 exclude reductions associated with the

State ofIndiana's vehicle inspection and maintenance program currently in place in Clark and

Floyd Counties, indiana.

• Emission inventories are required to be projected to future dates to assess the influence

growth and future controls will have. The Midwest Regional Planning Organization

(Midwest RPO) has developed growth and control files for Point, Area, and Non-road

categories. These files were used to develop the future year emissions estimates used in this

document. This was done so that the inventories used for redesignation are consistent with

modeling performed in the future.

The detailed inventory information for Clark and Floyd Counties for 2011 and 2020 is in

Appendix B. Emission trends are an important gauge for continued compliance ofthe ozone

stapdard. Therefore, IDEM performed an initialcomparison ofthe inventoriesfor the base year

(2003), interimyear (2011), and maintenance year (2020) for Clark and Floyd Counties, 9S.well

Note: Kentucky,emissions data is preliminary and subject to possible change.

VOC emissions within Clark and Floyd Counties are projected to decline by nearly 5% between

2003 and 2020. VOC emissions within the entire nonattainment area are projected to decrease

by over 16%. Areas source emissions, and, to a lesser extent, point sources show an increase due

to expectations that population will grow considerably in Clark and Floyd Counties.

17
NOx emissions within Clark and Floyd Comities are projected to decrease by over 26% between

2003 and 2020. NOx emissions within the entire nonattainrnent area are projected to decrease by

over 47%. In 2003, mobile sources comprised over 58% ofthe inventory. Emjssion reduction

benefits from U.S. EPA rules covering the NOx SIP Call, Tier 2 Motor Vehicle Emissions

S.tandards and Gasoline Sulfur Control Requirements\ Highway Heavy-Duty Engine Rules and

Non-Road Diesel Engine Rule6 are factored into the changes. Further, due to implementation of

the NOx SIP Call across the eastern United States, NOx and ozone levels entering this area will

also decrease. The Clean Air Interstate Rule (CAIR), issued in March 2005·and to be

implemented in ·Iate 2006, will reduce regional EGU NOx emissions by approximately another

15% in 2015. Since CAIR is a regional cap and trade program, it cannot be predicted at this time

what effect this will have on EGU units located in Floyd County or other upwind counties.

Therefore, potential reductions are not included in Graph 4.6 or Table 4.1.

4.4 Demonstration ofMaintenance

Ambient air quality data from all monitoring sites indicate that air quality in Clark arid Floyd

Counties met the NAAQS for ozone in 2005. Furthennore,ambient air quality data from aU

monitoring sites within the entire nonattainrnent'area iridicatethat air quality met the NAAQSfor

ozonein 2005. U.S.EPA'sRedesi~natidnGuidance(p:age 9) states, "A state'may generally .

.demonstrate maintenance ofthe NAAQS byei~er$hQml1gthat.fi!~ureemissionsofap<:)llutant

Qf its precursots will.not exceed the level ~ftheattaimli~nt inveritoiy, or by lllodelingio show'

that the future mixofsourqes andemiss'ionsrat¢s wilhnot cause a viqlation ofthe NAAQS." ...•.....

Emissions projections outlined in Section4.0ofthisdocum~ntclearly illustrate.that.VOCand .',

NOx emissions will continue to decline between the years of2003 (base year) and 2020. The

NOx SIP rule will result in major reductions ofEGU emissions (see Section 6.3). Section 7.0

further discusses the implications ofthese emissions trends and provides an analysis to support

these conclusions. Therefore, air quality should meet the ozone NAAQS through the projected

yearof2011 and 2020.

. In Indiana, major point sources in all counties are required to submit air emissions infonnation

once every three (3) years or annually, ifVOC potential to emit is greater than 250 tons or NOx

greater than 2500 tons, in accordance with the Emission Statement Rule, 326 lAC 2-6. IDEM

.prepares.a new periodic inventory for all ozone precursor emission sectors every three (3) years.

These ozone precursor inventories will be prepared for 2005,2008, and 2011, as necessary, to

comply with the inventory reporting requirements established in the CAM. Emissions

information will be 'compared to the 2003 base year and the 2020 projected maintenance year

inventories to assess emission trends, as necessary, to assure continued compliance with the

ozone standard.

4.5 Pennanent and Enforceable Emissions Reductions

Permanent and enforceable reductions of volatile organic compounds and oxides ofnitrogen '

have contributed to the attainment ofthe 8-hour ozone standard. Some ofthese reductions were

due to the application ofRACT rules and some were due to the application oftighter federal

standards on new vehicles. Also, Title IV ofthe Clean Air Act and the NOx SIP Call required the

reduction ofoxides of nitrogen from affected sources. Section 6.0 identifies the emission control

measures specific to Clark and Floyd Counties, as well as the implementation status of each

measure.

4.6 Provisions for Future Updates

As required by Section 175A(b) ofthe CAAA, Indiana commits to submit to the Administrator,

eight (8) years after redesignation, an additional revision ofthis SIP. The revision will contain

Indiana's plan for maintaining the national primary ozone air quality standard for ten (10) yea:-s

beyond the firSt ten (l0) year period after redesignation.

5.0 TRANSPORTATION CONFORMITY BUDGETS

Th~foJI()wing isa summary ofthe detailed mobile input and outputcalculationfiles located in

Appepgi?,E. ',. .

5.1 Overview

The Kentuckiana Regional Planning and Development Agency (KIPDA) is the Metropolitan

Planning Organization (MPO) for Clark and Floyd Counties in Indiana as well as Jefferson,

BuIIitt and Oldham Counties in Kentucky. This organization has a travel demand forecasting

model that is used to simulate the traffic in the area and is used to predict what that traffic would

be like in future years given growth' expectations. The model is used mostly to identifY where

travel capacity will be needed and to determine the infrastructure requirements necessary to meet

th~t need. It is also used to support the caicuiation'ofmobile source emissions. The travel

demand forecasting model is use~ to predict the total daily Vehicle Miles Traveled (VMT) and

an EPA software program called MOBILE6 is used to calculate the emissions per ~ile. The

product ofthese two outputs, once combined, is the total amount ofpollution emitted by the onroad vehicles for the particular analyzed area. ' ,

For the Louisville nonattainment area, a number ofagencies are involved in the emissions '

analysis. The Louisville Metro Air Pollution Control District (APCD) is the local air quality

agency. Staffat this agency create the MqBILE6 input'files used to detennine the emission

factors for the nonattainment area other than Bullitt and Oldham Counties. KIPDA determines

the average summer weekday VMT using output from the travel model and the APCD emission

factors are used to calculate the emissions for Clark, Floyd and Jefferson (KY) Counties. The

Kentucky Division for Air Quality (KYDAQ) determines the emission factors and the final

emission totals for Bulli~ and Oldham Counties using VMT and speed estim~tes develop¢ by

the Kentucky Transportation Cabinet (KYTC).

19
5.2 Emission Estimations

Table 5.1 outlines the on-road emission estimates for the entire nonattainment area for the years

2003,2011, and 2020. The 2003 emission estimates are based on the actual travel demand model

network for the year 2003. The 2020 emission estimates are based on the travel demand model

network projected to exist for 2020 under the 2030 Transportation Plan. The 2011 emission

estimates are interpolated values based on the travel demand model network projected to exist for

2009 and 2012 under the 2030 Transportation Pian. The emission estimates for Bullitt and

Oldham Counties have been developed by KYDAQ using VMT and speed data from the KYTC.

This document creates a single motor vehicle emissions budget for 2003 for the entire

,nonattainment area that 4escribes the maximum on-road emissions that cannot be exceeded,

between the years 2003 and 2020. This budget is equal to the on-road emissions calculated for

2003 and is consist~nt with the methodology and assumptions' used for the 2020 budget described

below. '

This document also creates a 'single motor vehicle emissions budget for 2020 for the entire

nonattainment area. This budget can not be exceeded in conformity analyses for the year 2020 or

later conformity-analysis years. This budget includes the emission estimates calculated for 2020' . ,

and an additional margin ofsafety. The safety margins include 6.03 tons/day for VOC and 9.84

tons/day for NOx. These correspond to approximately a 36% arid 50% increase from the 2020

on-road emissions, respectively. Margin~ of-safety are used to accomniodate the wide array of

assumptions that are factored into the calculation process. Since assumptions change over time, it

,20

.... -_ _-_.._------~---_.
is necessary to have a margin ofsafety that will accommodate the impact ofrefined assumptions

in the process. This budget ensures that the 2020 emissions for both VOC and NOx will be below

the nonattainment area's base year emissions shown in Table 4.2.

All methodologies, latest planning assumptions and the safety margins were detennined through

the interagency consultation process.

6.0 CONTROL MEASURES AND REGULATIONS

This section provides specific infonnation on the control measures implemented in Clark and

Floyd Counties, including CAAA requirements and additional state or local measures

implemented beyond CAAA requirements. .

6.1 Reasonably Available Control Technology (RACT)

As required by Section 172 ofthe CAAA, Indiana in the mid~ 1990s promulgated rules requiring

RACT for VOC emission sources. Local and statewide RACT rules have applied to new/existing'

sourceslocating in Clark and Floyd Counties since that time. The Illdiana rules are. found in 326

~AC 8. The. following is a listing of applicable statewide rulys: .

326 lAC 8-4 Petroleum Sources

326 lAC 8-5 Miscellaneous Operation

326 lAC 8-6 Organic Solvent Emission Limitations

RACT rules specific to Clark and Floyd Counties are summarized in Section 6.2.

6.2 Implementation oCPast SIP Revisions

Clark and Floyd Counties were previously nonattainment under the I-hour ozone standard. The

area met all ofits I-hour SIP obligations, and was redesignated to attainment in September of

2001. All ofthe control measures outlined within the 15% rate ofprogress (ROP) plan have been

fully implemented. Since the area was designated nonattainment for ozone under the 8-hour

standard in 2004 and its attainment plan is not due until 2007, now that the area has attained the

standard, no further SIP revisions are required.

The following outlines the measures implemented in association with previous SIP submittals

that have resulted in permanent and enforceable emission reductions in Clark and Floyd

Counties:

21
Fifteen Percent Rate ofProgress (ROP) Plan

Indiana's final 15% ROP plan was approved by U.S. EPA onMay 7, 1997. The measures included a mix

ofpoint, area, and mobile source control measures:

Mandatory Measures: The CAAA mandates certain control measures that may be included in

a state's 15% plan. These measures include tighter controls on a number of categories ofindustrial and

area sources. The mandatory measures that apply to Clark and Floyd Counties and were included in the

15% plan are:

• controls on automobile refinishing operations,

• wood furniture coatings,

• shipbuilding and ship repair operations,

• architectural and industrial maintenance coatings, and

• volatile organic liquids storage facilities.

All ofthese measures have b«m fully adopted and are effective within Clark and Floyd Counties, with the

exception ofthe architectural and industrial maintenance coatings rule. US EPA indicated in a September

10, 1993 memo from John Seitz, Director of Air Quality Planning and Standais, to Regional US EPA

Offices, that states may take credit for this federal rule without conducting state rulemaking. The

administrative code citations for the state rules are as follows; .

AdditionalMeasures: In order to achieve the necessary emission reductions, additional measuresvere

selected by Indiana for impementation in Clark and Floyd Counties. The additional measures were:

•

. • a ban on residential open burning,

• installation ofgas collection and combustion equipment at municipal solid waste landfills,

• a ridesharing program, and'

• the installation oftherIilal 'incinerators at a printing facility.in Girk County:

6.3 Nitrogen Oxides (N01f) Rule

The U.S. EPA NOx SIP Call required twenty-two (22) states to adopt rules that would result in

significant emission reductions from large EGUs, industrial boilers, and cement kilns in the

eastern United States. Indiana adopted this rule in 200 I. Beginning in 2004, this rule will

account for a reduction of approximately thirty-one percent (31 %) of all NOx emissions statewide

compared to previous uncontrolled years.

Twenty-one other states have also adopted these rules. The result is that significant reductions

will occur upwind and within the nonattainment area because ofthe number oflarge electric

utilities located in southern Indiana, Illinois, Kentucky, and Tennessee. U.S. EPA and IDEM

performed modeling that indicates this area will attain the 8-hour ozone standard with the

implementation ofthe NOx SIP Call. Controls for EGUs formally commenced May 31, 2004.

From Graph 4.3, "Statewide NOx Emissions from Electric Generating Units" it can be seen that

emissions'covered by this program have been generally trending downWard since 1998 with

larger reduction occurring in 2002 and 2003.' Table 6.1, compiled from data taken from the U.S.

EPA Clean Air, Markets website, quantifies the gradual NOx reductions that have occurred in

Indiana as a result ofTitle IV ofthe Clean Air Act Amendments and the beginning ofthe NOx

SIP Call Rule. This cap will stay in place through 2008, at which time the CAIR program Will

6.4 Measures Beyond Cle<l? Air Act "Requirements

Reductions in ozone precursor emissions have occurred, or are anticipated to occur, as a result of

federal control programs. These additional control measures' include: .

Tier II Emission Standards for Vehicles and Gasoline Sulfur Standards

In February 2000, U.S. EPA finalized a federal rule to significantly reduce emissions

from cars and light trucks, including sport utility vehicles (SUVs). Under this proposal,

automakers will be required to sell cleaner cars, and refineries will be required to make

cleaner, lower sulfur gasoline. This rule will apply' nationwide. The federal rules will

phase in between 2004 and 2009. U.S. EPA has estimated that NOx emission reductions

will be approximately seventy·seven percent (77%) for passenger cars, eighty-six percent

(86%) for smaller SUVs, light trucks, and minivans, and sixty-five to ninety-five percent

(65-95%)reductions for larger SUVs, vans, and heavier trucks. VOC emission .

reductions will be approximately twelve percent (12%) for passenger cars, eighteen

percent (18%) for smaller SUVs, light trucks, and minivans, and fifteen percent (15%) for

larger SUVs, vans, and heavier trucks.

Clean Air Non-Road Diesel Rule

In May 2004, U.S. EPA issued the Clean Air Non-Road Diesel Rule. This rule applies to

diesel engines used in industries such as construction, agriculture, and mining. It also

contains acleaner fuel standard, similar to the highway diesel program. The new

standards will cut emissions from non-road diesel engines by over ninety percent (90%).

Non-road diesel equipment, as described in this rule, currently accounts for forty·seven

percent (47%) ofdiesel particwate matter (PM) and twenty-five percent (25%) of

nitrogen ~xides (NO,,) from mobile sources' nationwide. Sulfur levels will be reduced in

non-road diesel fuel by ninety-nine percent (99%) from current levels, from

approximately three-thousand (3,000) parts per million (ppm) now to (fifteen) 15 ppm in

20IO. New engine standards take effect, based on engine horsepower, starting in 2008.

Together, these rules will substantially reduce local and regional sources ofozone precursors.

The modeling analyses discussed in Section 7 include these rules and show the ozone

concentrations expected to result from the imple~entation ofthese rules.

24
6.5 Controls to Remain in Effect

Indiana·commits to maintain the control measures necessary to maintain attainment ofthe2lJl)ne standard

6.6 New Source Review Provisions

Indiana has a longstanding and fully implemented New Source Review (NSR) progranthat is outlined in

rule 326 lAC 2. The rule includes provisions for the Prevention of Significant Deterioration (PSD)

permitting program in 326 lAC J.2. Indiana's PSD program was conditionally approved on March 3, 2003

(68 FR 9892) and received approval on May20, 2004 (69 FR 29071) by U.S. EPA as part ofthe SIP.

Any facility that is not listed in the 2002 emission inventory, or for the closing ofwhich credit was tamn

demonstrating attainment, will not be allowed to construct, reopen, modify, or reconstruct without meeting

'all applicabl~ permit rule requirement. The review process will be identical to that used for new sources.

Once the area is redesignated, OAQwill implement NSR through the PSD prograJt) which requires an air

quality analysis to evaluate whether the new source will threaten the N~AQS. '

7.0 MODELING

Although U.S. EPA's redesignation guidance does riot require modeling for ozone nonattainmentareas

seeking redesignation, extensive modeling has been performed coverin~outhem Indiana to determine the

effect of national emission control strategies on ozone levels. These modeling analysdiave determined

that Clark and Floyd Counties are significantly iqoacted by ozone and ozone precursor transport, and

regional NO. reductions are an effective way to attain the 8hour standard in this area. Future year

modeled ozone concentrations are expected to be reduced by 10% to 20% from baseline design values.

Examples ofthese modeling analyses are listed below.

7.1 Summary ofModeling- Results for National Emission Control Strategies in Final Rulemakings

u.S. EPA Modeling Analysis for HDE Final Rulemaking

U.S. EPA conducted modeling for Tier II vehicles and low-sulfur fuels. This analysis was

performed in 2000 to support final rulemaking for the Heavy D'uty Engine (HOE) and Vehicle

Standards and Highway Diesel Fuel and its expected impact on ozone levels. "Technical Support

Document for the Heavy Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur

Control Requirements: Air Quality Modeling Analyses" (EPA42o-R-00-028) was referenced in

support ofthis ozone redesignation for the two counties. Base year emissions from 1996 were

modeled for three ozone episodes: June 12-24, 1995; July 5-15, 1995; and August 7-21, 1995.

Results ofthis modeling show that ozone impacts from these fuel emission control measures"as

well as the NOx SIP call, would be substantial in Clark and Floyd County. Relative Red1.£tion

Factors (RRF) were calculated for each monitor in Clark and Floyd County for future years 2007

and 2020. These RRFs were applied to the three-year (2001-2003) design valuC?s of92.0 ppb in

Clark CountY and 86.3 ppb in Floyd County. The resulting future year design values for 2007

and 2020 were calculated and shown below in Table 7.1. The modeled future year design values

for all monitors in Clark and Floyd Counties were reduced by 11%to 13% ofthe 2001-2003

design values and will attain the 8-hour ozone NAAQS of 8~ ppb.

LADCO Modeling Analysis for 8-Hour Ozone Standard Assessment

The Lake Michigan Air Directors Consortium (LADCO) performed modeling to evaluate the

effect ofthe NOx SIP Call and Tier II I Low Sulfur rule for future-year 2007 ozone, which

included Clark and Floyd Counties. This modeling was originally designed to assess the I-hour

ozone standard. Further analysis was conducted and documented in LADCO's White Paper "8-

Hour Ozone Assessment," dated May 2, 2001. Base year design values used were the average of

the design values for the three 3-year periods(1994-1996, 1995-1997, and 1996-1998). Base

year emissions·were taken from 1996 and four ozone episodes were evaluated: June 22-28, 1991;

July 14-21, 1991; June 13-25, 1995; and July 7-18, 1995. Results are shown in Table 7.2.

The resulting future year design values were calculated at 84 ppb for Clark County and Floyd

County, respectively. The modeled future year design values will attain the 8-hour ozone

NAAQS of85 ppb with future year concentrations decreasing by 8% to 10%. Base-year av~rage

design values (1994-1996, 1995-1997, 1996-1998) used in the LADCO modeling were 6 to 8

ppb greater than current base-year average design values (2001-2003, 2002-2004, 2003-2005)'for

most monitors. Therefore, the modeling results would be even lower ifthe current base year

average design values were used. The trend for the design values at both monitors has trended

downward over this time period.

It should be noted, that thisniodelingwas conducted in the year 2000 and used 1996 emission

inventories. More recentmodeling uses updated emission inventories from 2002 with revised

7.2 Summary ofModelirig Results to Support Rulemakings

u.s. EPA Modeling for Clean Air Interstate Rule (CAIR), 2005

. , ,

On March 10,2005, the U.S. EPA finalized the Clean Air Interstate Rule (CAIR). NO" emissions

from power plants will be cut by 1.7 million tons by 2009 and emissions will be reduced by 1.3

million tons in 2015 in 28 eastern states and the District ofColumbia. Compared to a 2003 '

baseline, Indiana will reduce NOx emissions by 113,000 tons by 2009 and 149,000 tons by 2015.

U.s. EPA performed modeling to support the associated emission reductions. The modeling was

based on 1999 - 2003 design values. Future year modeling was conducted, including Clark and

Floyd Counties, and the future year design values for 2010 and 2015 were evaluated for

attainment ofthe 8-hour ozone NAAQS, as shown below in Table 7.3. This future year

modeling excluded reductions associated with the State ofIndiana's vehicle ins~ction and

maintenance program currently in place in Clark and Floyd Counties, Indiana Results ofthe

CAIR modeling show that both counties will attain the 8-hour ozone NAAQS in 2010 with

modeled concentrations'reduced by.10 % to 12% and remain below 85 ppb. With further

reductions projected in CAIR for 2015, all design values continue to decrease by 16% to 18%

and continue to attain the 8-hour ozone NAAQS.

will be 8% lower than baseline ozone design values and 12% lower in 2012. Ozone

concentrations are predicted to continue to decrease and remain in attainment ofthe 8-hour ozone

NAAQS of85 ppb.

7.3 Summary ofExisting Modeling Results

U.S. EPA and LADCO modeling for future year design values have consistently shown that

existing national emission control measures will bring Clark and Floyd Counties into attainment

ofthe 8-hour ozone NAAQS. Rulemakings to be implemented in the next several years will

provide even greater assurance that air quality will continue to meet the standard into the future.

Modeling support for the NOx SIP Call, Heavy Duty Engine and Highway Diesel Fuel and Tier

IIlLow Sulfur Fuel and Clean Air Interstate Rule has shown that future year design values for

Clark and Floyd Counties will attain the ozone standard with modeled future year design values

below 85 ppb. U.S. EPA has modeled base case future years with existing emission controls

only ~d shown that Clark and Floyd Counti~s.will attain the 8-hour ozone NAAQS without

addit~onal national emission control strategies. Future natigl1al and local emission control

strategies will ensure that each county's attainment will be maintained with an increasing margin

ofsafety over time. .

7.5 Summary ofMeteorological Conditions

The analysis ofthe departure·from normal ofthe maximum temperatures during the summer

months shows variation in the number of90° F days per year as illustrated in Table 7.6. The

analysis shows that 30 or more days with temperatures of9(f F and higher occurred in 1995,

1999, 2002 and 2005. The number of8-hour ozone exceedance days for those years shows a

greater correlation to the number ofhigher temperature days. Howev~r, the years with a lesser

number of90° F days still yielded 8-hour ozone exceedance days. Ozone formation in the future

will be influenced less by meteorological conditions. Lower ozone values correspond to lowered

local and regional ozone precursor emissions. This is why U.S. EPA developed the 8-hour

standard as a 4th high ozone value averaged over 3 years to account for variations in temperanrre.

Despite such variations, ozone values in Clark and Floyd counties have steadily decreased since

1995..

8.0 CORRECTIVE ACTIONS

8.1 Commitment to Revise Plan

As noted ~n Section 4.6 above, Indiana hereby commits to review its Maintenance Plan eight (8)

years after redesignation, as required by Section 175(A) ofthe CAAA.

8.2 Comrilitment for Contingency Measures

Indiana hereby commits to adopt and implement expeditiously necessary corrective actions in the

following circumstances:

Warning Level Response

A Warning Level Response shall be prompted whenever an annual (I-year) fourth high

monitored value of.089 ppm occurs in a single ozone season, or a two (2)-year average

fourth high monitored value 0t085 p~s per million (ppm) or greater occurs within

Indiana's portion ofthe maintenaricearea.A Warning Level Response will consist of a

Should it be detennined through the Warning L.evel study that action is necessary to

reverse the noted trend, the procedures for control selectio~ and implementation outlined

under "Action Level Rel)ponse" shall be followed.

Action Level Response

An Action Level Response shall be prompted whenever a violation ofthe standard (three

(3)-year average fourth high monitored value of.085 parts per million (ppm) or greater)

occurs within the maintenance area. In the event that the Action Level is triggered and is

not found to be due to an exceptional event, malfunction, or noncompli~cewith a pennit

condition or rule requirement, IDEM willdetennine additional control measures needed

,to assure future attainment ofNAAQS for ozone. In this case, measures that can be

implemented in a short time will be selected in order to be in place within eighteen (18)

months from the close ofthe ozone season that prompted the Action Level.

32
Control Measure Selection and Implementation

Adoption of any additional control measures is subject tcthe necessary administrative and legal

process. This process will include publication ofnotices, an opportunity fopublic hearing, and

other measures required by Indiana law for rulemaking by state·environmental boards.

.If a new measure/control isalready promulgated and scheduled tobe implemented at the federalor

state level, and that measure/control is determind to be sufficient to addressthe upward trend in

air quality, additional local measures may be unnecessary.Furthermore, Indiana will submit to

U.S. EPA an analysis to demonstratethe proposed measures are adequate to return the area to

attainment.

8.3 Contingency Measures

Contingency measures to be considered will be selected from a comprehensive list ofmeasures deemed

appropriate and effective at the time the selection is made. Listed below arexample measuresthat may.be

considered. The selection cfmeasures will be based upon costeffectiveness, emission reduction potential,

economic and social considerations or other factors that IDEM deems appropriate. IDEM will solicit input

from all interested and affected persons in the maintenance area prioto selecting appropriate contingency

measures. All ofthe listed coritingencymeasures are potentially effective or proven methods ofobtaining

significant reductions ofozone precursor emissions.. Because it is not possible at this time to determine

wha,t control measure. will be appropriate~t an llnspecified time in the future, the listofcontingency

3) Tighten RACT on existing sources covered by U.S. EPA Contol Technique Guidelines issued in

response to the 1990 CAAA.

4). Apply RACT to smaller existing sources.

5) One or more transportation control measures sufficient to achieve at least halfa percent (0.5%)

reduction in actual area wide VOC emissions. TranspaJtation measures will be selected from the

following based upon the factors listed above after consultation with affected local governments:

a) Trip reduction programs, including, but not limited to, employed>ased transportation

management plans, area widerideshare programs, work schedule changes, and telecommuting.

b) Transit improvements.

10.0 CONCLUSIONS

Clark and Floyd Counties, along with the remaining portion ofthe Louisville basic ozone

nonattainment area, have attained theNAAQS' standard for ozone. This petition demon~trates

that Clark and Floyd CoUnties have complied with the applicable provisions ofthe 1990

34
Amendments to the Clean Air Act regarding redesignation ofbasic ozone nonattainment areas.

IDEM has prepared a State Implementation and Maintenance Plan that meets the requirement of

Section 110 (a) (I)ofthe 1990 Clean Air Act.

Indiana has performed an analysis that shows the air quality improvements are due to permanent

and enforceable measures~ In addition, significant regional NOx reductions will ensure continued

compliance (maintenance) with the standard and that all CAAA requirements necessary for

redesignation have been met.

Indiana has performed an analysis that shows the air quality improvements are due to permanent

and enforceable measures and that significant regional NOx reductions following implementation

ofPhase II NOx and CAIR will ensure continued compliance (maintenance) with the standard.

Based on this presentation, Indiana's portion ofthe nonattainment area (Clark and Floyd .

Counties) meets the requirements for redesignation under the CAA (Section 107 (d)(3» and U.S.

EPA guidance. Furthermore, because this area is subject to significant transport ofpollutants,

significant regional NOx reductions will ensure continued compliance (maintenance) with the

standards with an increasing margin ofsafety.

Consistent with the authority granted to the U.S. EPA, the State ofIndiana hereby requests that

Clark and Floyd .counties be redesignated to attaillll1ent simultaneously with U.s. EPA approval·

: ofthe Illdiana Statt:JmplementationandryIaintenance Plan provisions con~ed herein.' .

IDEM

1 share the results of the technical evaluation that

2 supports this revision.

3 IDEM recently submitted an 8-Hour

4 Ozone Redesignation Petition and Maintenance Plan

5 for Clark and Floyd Counties dated July, 2006, t6

6 the u.s. EPA requesting that these Counties be

4

7 redesignated to attainment of the standard. Clark

8 and Floyd Counties, along with the remaining portion

9 of the Louisville nonattainment area, have attained

10 the National Ambient Air Quality standard for ozone.

11 Indiana has performed an analysis

12 that shows the air quality improvements are due to

13 permanent and enforceable measures and that

14 significant regional reductions of oxides of

15 nitrogen following implementation of Phase II of the

16 NOxSIP Call and the Clean Air Interstate Rule will

17 ensure continued compliance or maintenance with the

18 standard.

19 Indiana's petition includes a long20 term maintenance plan that will be implemented to

21 ensure that the area continues to meet the 8-hour

22 standard for ground-level ozone through the year

23 2020. Indiana also committed to maintain all

24 emission control measures necessary to maintain

25 continued compliance with the standard following

1 redesignation.

2 The vehicle inspection and

3 maintenance program was first initiated in 1984 in

4 accordance with the Clean Air Act. This program was

5 augmented in 1997 to a fully enhanced vehicle

6 inspection and maintenance program and was

7 incorporated within Indiana's I-hour ozone State

8 Implementation Plan in 1996. Although the U.S. EPA

9 revoked the I-hour ozone standard on June 15th,

10 2005, Clark and Floyd Counties were designated

11 nonattainment for the 8-hour ozone standard

12 effective June 15th, 2004. Therefore, the program

13 is required to be in place until all applicable

14 Clean Air Act requirements are met.

15 The vehicle inspection and

16 maintenance program is authorized by state statute,

17 IC 13-17-5, paid for by the state general fund and

18 implemented through rules promulgated by the Air

19 Pollution Control Board at 326 lAC 13-1.1. The

20 program tests approximately 7 percent of the

21 registered automobiles in the Greater Louisville

22 Basic Ozone Nonattainment Area and costs the State

23 of Indiana approximately one million dollars per

24 year to operate and maintain. The program yields

25 less than a one percent reduction in total oxides of

1 nitrogen and volatile organic compound emissions for

2 the nonattainment area.

3 On July 1, 2003, an amendment to

4 IC 13-17-5 became effective that terminates

5 Indiana's vehicle inspection and maintenance rule

6 for Clark and Floyd Counties after December 31st,

7 2006, and directs the Air Pollution Control Board to

6

8 amend 326 lAC 13-1.1 to reflect this change~ IDEM

9 is in the process of amending the state rule to

10 accommodate the discontinuation of the vehicle

11 inspection and maintenance program in Clark and

12 Floyd Counties. IDEM has also revised the 8-hour

13 Redesignation Petition and Maintenance Plan for

14 Clark and Floyd Counties in order to move the

15 vehicle inspection and maintenance program from

16 Section 6.2, where it was listed as a measure to

17 remain in place over the course of the maintenance

18 plan, to 'Section 8.0, where it is listed as a

19 contingency measure.

20 IDEM has also revised Section 6.0 to

21 clarify that Indiana in the mid-1990s promulgated

22 rules specific to Clark and Floyd Counties that

23 require RACT (Reasonably Available Control

24 Technology) for new and existing sources of volatile

25 organic compounds locating in these counties.

IDEM

In order to support the revision to

7

2 the 8-hour Redesignation P~tition and Maintenance

3 Plan for Clark and Floyd Counties, IDEM has prepared

4 a demonstration that meets the requirements of

5 Section 110(1) of the Clean Air Act, hereinafter

6 referred to as the Section 110(1) demonstration.

7 This demonstration is supported by photochemical

8 modeling and an emissions analysis. Photochemical

9 modeling shows that NOx emissions will increase by

10 .78 tons per summer day and .82 tons per winter day

11 with a discontinuation of the vehicle inspection and

12 maintenance program. Volatile organic compound

13 emissions will also increase by .79 tons per summer

14 day and 1.49 tons per winter day.

15 Despite this fact, 2007 total

16 emissions are projected to be less than the total

17 2002 emission levels, which is the base year for the

18 PM 2.5 standard, 2003 total emissions, the base year

19 for the ozone maintenance plan, and 2009 total

20 emissions, which is the deadline for monitoring

21 attainment under the new PM 2.5 standard.

22 The 2010 and 2020 total emission

23 levels referenced In the ozone maintenance plan are

24 also projected to be less than the total 2003

25 emission levels. Therefore, the discontinuation of

IDEM

1 the vehicle emlSSlons testing program will not

2 interfere with attainment of the 8-hour ozone

3 standard in Clark and Floyd Counties or elsewhere

4 within the nonattainment area.

8

5 Furthermore, this demonstration shows

6 that the discontinuation of the vehicle emissions

7 testing program will not interfere with the area's

8 reasonable progress tow~rds attainment of the

9 National Ambient Air Quality Standard for fine

10 particles or PM 2.5.

11 This concludes my remarks concernlng

12 this matter. This hearing is now open for public

13 comment. Any public comment? I have not received

14 any appearance blanks.
