Re: Indiana Infrastructure State Implementation 

Plan for Sulfur Dioxide (S02) 

The Indiana Department of Environmental Management (IDEM) submits the 

enclosed sulfur dioxide (S02) Infrastructure State Implementation Plan (SIP) for Indiana. 

This submittal demonstrates that the State of Indiana continues to retain the resources 

and authority necessary to implement the 2010 S02 National Ambient Air Quality 

Standard (NAAQS). IDEM requests that the United States Environmental Protection 

Agency (U.S. EPA) process this final submittal for approval as a revision to Indiana's 

State Implementation Plan. 

IDEM provided an opportunity for public hearing regarding the S02 Infrastructure 

SIP if a request for a public hearing was received by May 1, 2013. No request for a 

public hearing was received and the hearing was cancelled. In addition, IDEM received 

no comments during the public notice process, which closed on May 17, 2013. All 

documents related to the public participation process are included under Enclosure 2 of 

this submittal. 

The S02 Infrastructure SIP submittal demonstrates IDEM's authority and ability to 

evaluate ambient air quality through both monitoring and modeling, as well as maintain 

enforceable emissions limitations and compliance requirements. The S02 Infrastructure 

SIP also demonstrates IDEM's ability satisfactorily implement all other requirements 

under Section 11 0 of the federal Clean Air Act (CAA) with regards to the 2010 S02 

NAAQS. 

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 Doug Aburano, Chief of U.S. EPA Region 5's Attainment Planning and 

Maintenance Section.

2010 Sulfur Dioxide (S02) National Ambient Air 

. Quality Standards (NAAQS) 

May 2013 

IDEM 
S02 Infrastructure SIP 

State of Indiana 

Preface: The Indiana Department of Environmental Management's (IDEM) ability to 

confirm the required technical capacity in order to implement the 2010 Sulfur Dioxide 

(S02) National Ambient Air Quality Standard (NAAQS) is reliant on an implementation 

structure not yet put into place by U.S. EPA at the time of submittal. 

Indiana's Infrastructure State Implementation Plan (SIP) submittal was developed 

in consultation with United States Environmental Protection Agency (U.S. EPA) Region 

V and in accordance with 40 Code of Federal Regulations (CFR) 51, Appendix V, 

"Criteria for Determining the Completeness of Plan Submissions." The SIP elements 

listed below are required under Section 11 O(a)(2) of the federal Clean Air Act (CAA). 

Section 11 O(a)(1) provides the procedural and timing requirements for SIPs. Section 

11 O(a)(2) lists the basic or "infrastructure" elements that all SIPs must contain. 

Following each Section 110(a)(2) element is the Indiana Department of Environmental 

Management's (IDEM) discussion of the department's ability to fulfill the requirement. 

Indiana Infrastructure SIP Submittal: Section 11 0(a)(2) Elements 

Section 11 O(a)(2)(A) - Emission Limits and Other Control Measures: Section 

11 O(a)(2)(A) requires SIPs to include enforceable emission limits and other control 

measures, means or techniques, as well as schedules and timetables for compliance. 

IDEM continues to update and implement needed revisions to Indiana's SIP, as 

necessary, to meet the National Ambient Air Quality Standards (NAAQS). The 

authority to adopt emission standards and compliance schedules can be found at 

Indiana Code (IC) 13-13-8, IC 13-17-3-4, IC 13-17-3-11, and IC 13-17-3-14. 

In order to ensure attainment and maintenance of the 2010 S02 NAAQS, IDEM 

has established emission limitations for sulfur dioxide sources (326 Indiana 

Administrative Code (lAC) 7-1.1}, as well as compliance requirements (326 lAC 

7-2) and ambient monitoring requirements (326 lAC 7-3). In addition, emission 

limitations and requirements have been set specifically for Dearborn, Floyd, 

Gibson, Jefferson, LaPorte, Marion, Morgan, Porter, Sullivan, Vermillion, Vigo, 

Warrick, and Wayne counties (326 lAC 7-4), as well as Lake County (326 lAC 7-

4.1). 

U.S. EPA issued preliminary designations for Veale Township in Daviess County, 

Center, Perry, and Wayne Townships in Marion County, Clay and Washington 

Townships in Morgan County, Washington Township in Pike County, Fayette, 

Harrison, and Otter Creek Townships in Vigo County, and Wayne Township in 

Wayne County as "nonattainment" for the 2010 SOz 1-hour standard on February 

6, 2013. IDEM provided U.S. EPA with a response to the proposed designations 

on March 11 and March 28, 2013 and expect final designations to be issued in 

June 2013 (after this submittal is expected to be made). Under the previous 

1971 standard, five counties (Lake, LaPorte, Marion, Vigo, and Wayne) were 

designated as nonattainment and subsequently redesignated to attainment. 

1 
S02 Infrastructure SIP 

State of Indiana 

IDEM notes that, consistent with U.S. EPA's historical guidance for infrastructure 

SIPs such as the 2006 PM2.s NAAQS and the 2008 Lead NAAQS, the emissions 

limitations and other control measures needed to attain the NAAQS in areas 

designated as non attainment for the 2010 S02 1-hour standard will be due on a 

different schedule from the requirements of this infrastructure SIP and will be 

reviewed and acted upon with regard to approvability for the specific purposes of 

such an attainment plan under Part D of the federal CAA through a separate 

process at a later time. 

Section 110(a)(2)(B)- Ambient Air Quality Monitoring/Data System: Section 

11 O(a)(2)(B) requires SIPs to include provisions that provide for the establishment and 

operation of appropriate devices, methods, systems, and procedures necessary to 

monitor, compile, and analyze data on ambient air quality, and upon request, make 

such data available to U.S. EPA. 

U.S. EPA requires states to submit an annual monitoring network plan. This 

network plan is required to provide the framework for the establishment and 

maintenance of an air quality surveillance system and to list any changes that are 

proposed to take place to the current network. 

In accordance with its SIP, IDEM operates an ambient air monitoring network. 

The data is used to determine compliance with U.S. EPA's NAAQS. IDEM's 

approved 2013 Ambient Air Monitoring Network Plan documents the framework 

for the establishment and maintenance of Indiana's air quality surveillance 

system and lists any changes that are proposed to take place to the current 

network during 2013. In accordance with 40 CFR 58, IDEM submits monitored 

data to U.S. EPA's Air Quality System (AQS) in a timely manner. 

IDEM maintains the resources needed to implement both the monitoring and 

modeling of sources with respect to the NAAQS. However, with no 

implementation rule in place at the time of this submittal, IDEM cannot identify 

the tools and resources necessary to adequately address the implementation 

requirements. IDEM is committed to working with U.S. EPA in order to address 

any necessary changes in monitoring requirements once the necessary 

implementation rules have been issued. Currently, IDEM's rules regarding 

monitoring can be found at 326 lAC 3, and rules relating to modeling are found at 

326 lAC 2-2-4, 326 lAC 2-2-5, 326 lAC 2-2-6, and 326 lAC 2-2-7. 

Section 11 O(a)(2)(C)- Programs for Enforcement of Control Measures, Prevention 

of Significant Deterioration (PSD), and New Source Review (NSR): Section 

11 O(a)(2)(C) requires SIPs to include a program to provide for the enforcement of 

emission limits and other control measures, and regulation of the modification and 

construction of any stationary source within areas covered by the plan, as necessary, to 

assure that the NAAQS are achieved, including a permit program. 

2 
S02 Infrastructure SIP 

State of Indiana 

IDEM maintains an enforcement program in order to ensure compliance with SIP 

requirements. IC 13-14-1-12 provides the Commissioner with the authority to 

enforce rules "consistent with the purposes of the air pollution control laws." The 

commissioner also has the authority, under IC 13-14-2-6, 13-14-2-7, IC 13-17-3-

3, and 13-30-3 to assess civil penalties and obtain compliance with any 

applicable rule a board has adopted in order to enforce air pollution control laws. 

Additionally, IC 13-14-10-2 allows for an emergency restraining order that will 

require "any person causing or contributing to the alleged pollution to stop the 

introduction of contaminants causing or contributing to the pollution." 

IDEM's SIP-approved PSD rules are found in 326 lAC 2-2 and it is IDEM's 

intention that these rules satisfy the requirements of Section 11 O(a)(2)(C) and the 

applicable requirements of Section 11 O(a)(2)(D), as well as the applicable 

requirements of Section 110(a)(2)(D). IDEM has adopted a rule change titled 

"2012 NAAQS Update" (LSA #12-51 0), which updates PMzs, NOz, and SOz 

NAAQS to match federal NAAQS. This rule became effective on February 15, 

2013 and ensures that IDEM's SIP-approved PSD program addresses the most 

current NAAQS, including the 2010 SOz NAAQS. 

IDEM implements its PSD permit program while ensuring that the construction 

and modification of major stationary sources do not cause or contribute to a 

violation of the S02 NAAQS, or any other standard, in accordance with the rules 

found in 326 lAC 2-2. 

Furthermore, IDEM's EPA-approved PSD SIP includes provisions that satisfy 

EPA's requirements set forth in 40 CFR 52.21 and analogous sections of 40 CFR 

51.166. As a result, the applicable infrastructure SIP requirements related to 

PSD are met and include the provisions required by the 2008 PM2.5 NSR Rule, 

and the 2010 PM2.5 NSR Rule. Final approval of the requirements related to the 

2008 NSR Rule was published in the Federal Register on October 29, 2012 (77 

FR 65478). On December 10, 2012, IDEM submitted to U.S. EPA a letter 

requesting approval of mandated portions of the 2010 NSR Rule, including the 

PM2.5 increments. As noted above, IDEM requests that approval of these 

submissions satisfies the requirements contained in 40 CFR 52.21 and 40 CFR 

51.166, as well as the applicable infrastructure SIP requirements related to PSD, 

contained in Section 11 O(a)(2)(C), Section 11 O(a)(2)(D), and Section 

11 O(a)(2)(J). IDEM ensures that new or modified sources will apply the Best 

Available Control Technology (BACT) to reduce S02 emissions in accordance 

with the rules found in 326 lAC 2-2-3. 

With respect to the permitting of greenhouse gas (GHG) emitting sources, U.S. 

EPA finalized approval of revisions to Indiana's PSD SIP on September 28, 2011 

(76 FR 59899). These revisions include the adoption of the Federal thresholds 

for PSD permitting of GHG-emitting sources. Indiana has therefore satisfied the 

3 
S02 Infrastructure SIP 

State of Indiana 

GHG permitting requirements for Section 11 O(a)(2)(C), Section 11 O(a)(2)(D), and 

Section 11 O(a)(2)(J). IDEM also observes that with the adoption of the Federal 

thresholds for PSD permitting of GHG-emitting sources, the requirements of 

Section 11 O(a)(2)(E) have been met, specifically as they relate to the necessary 

resources and personnel for such permitting purposes. 

IDEM observes that there is some degree of ambiguity in the draft guidance for 

the 2010 SOz NAAQS as it relates to the evaluation of our minor source NSR 

program. Consistent with an earlier U.S. EPA proposed action for the 1997 

Ozone and PM2.5 NAAQS (76 FR 23757), IDEM's minor source NSR program 

was most recently approved by U.S. EPA on October 7, 1994 (59 FR 51108) and 

covers the applicable NAAQS, i.e., S02, and this approval adequately addresses 

SOz emissions. 

Section 11 O(a)(2)(D)(i) - Interstate Transport- Significant Contribution and 

Interference with Maintenance: Section 11 O(a)(2)(D)(i) requires SIPs to include 

provisions prohibiting any source or other type of emissions activity within the state from 

emitting any air pollutant in amounts which will contribute significantly to nonattainment 

in, or interfere with maintenance by, any other state with respect to any national primary 

or secondary ambient air quality standard. 

In response to the Clean Air Interstate Rule (CAIR), IDEM adopted 326 lAC 24-2. 

IDEM's rule included an SOz emissions budget and trading program. In 2008, 

the District of Columbia (D.C.) Circuit Court issued a remand without vacatur of 

CAIR. U.S. EPA replaced CAIR with the Cross-State Air Pollution Rule 

(CSAPR), which was vacated in 2012. The D.C. Circuit Court directed U.S. EPA 

to continue administering CAIR until a valid replacement is found. Thus, IDEM 

continues to enforce 326 lAC 24-2. 

In order to ensure the attainment and maintenance of the 2010 S02 NAAQS, 

IDEM has established emission limitations for sulfur dioxide sources (326 lAC 7-

1.1), as well as compliance requirements (326 lAC 7-2) and ambient monitoring 

requirements (326 lAC 7-3). In addition, emission limitations and requirements 

have been set specifically for Dearborn, Floyd, Gibson, Jefferson, LaPorte, 

Marion, Morgan, Porter, Sullivan, Vermillion, Vigo, Warrick, and Wayne counties 

(326 lAC 7-4), as well as Lake County (326 lAC 7-4.1). 

U.S. EPA issued preliminary designations for Veale Township in Daviess County, 

Center, Perry, and Wayne Townships in Marion County, Clay and Washington 

Townships in Morgan County, Washington Township in Pike County, Fayette, 

Harrison, and Otter Creek Townships in Vigo County, and Wayne Township in 

Wayne County as "nonattainment" for the 2010 SOz 1-hour standard on February 

6, 2013. IDEM provided U.S. EPA with a response to the proposed designations 

on March 11 and March 28, 2013 and expect final designations to be issued in 

June 2013 (after this submittal is expected to be made). Under the previous 

4 
S02 Infrastructure SIP 

State of Indiana 

1971 standard, five counties (Lake, LaPorte, Marion, Vigo, and Wayne) were 

designated as nonattainment and subsequently redesignated to attainment. 

Section 11 O(a)(2)(D)(i) - Interstate Transport- Prevention of Significant 

Deterioration and Protect Visibility: Section 11 O(a)(2)(D)(i) requires SIPs to include 

provisions prohibiting any source or other type of emissions activity within the state from 

emitting any air pollutant in amounts which will interfere with applicable implementation 

measures used by another state to protect visibility or to prevent significant deterioration 

of air quality. 

IDEM's SIP-approved PSD rules are found in 326 lAC 2-2 and it is IDEM's 

intention that these rules satisfy the requirements of Section 11 O(a)(2)(C), as well 

as the applicable requirements of Section 11 O(a)(2)(D). U.S. EPA issued 

preliminary designations for Veale Township in Daviess County, Center, Perry, 

and Wayne Townships in Marion County, Clay and Washington Townships in 

Morgan County, Washington Township in Pike County, Fayette, Harrison, and 

Otter Creek townships in Vigo County, and Wayne Township in Wayne County 

as "nonattainment" for the 2010 S02 1-hour standard on February 6, 2013. 

IDEM provided U.S. EPA with a response to the proposed designations on March 

11 and March 28, 2013 and expect final designations to be issued in June 2013 

(after this submittal is expected to be made). Under the previous 1971 standard, 

five counties (Lake, LaPorte, Marion, Vigo, and Wayne) were designated as 

nonattainment and subsequently redesignated to attainment. U.S. EPA's 

distinction of "interference with PSD" in this instance is not an issue in Indiana, as 

there are no areas currently designated as nonattainment. As noted above, the 

timeframe for submitting attainment demonstrations for newly designated 

nonattainment areas under the 2010 S02 NAAQS are independent of the timing 

requirements of submitting this infrastructure SIP. 

Indiana is also subject to the regional haze program that addresses visibilityimpairing pollutants, and has implemented regional haze rules at 326 lAC 26. In 

conjunction with Indiana's EPA-approved PSD program and EPA-approved 

nonattainment NSR program (October 7, 1994), IDEM believes that it has met 

the visibility protection requirements of Section 11 O(a)(2)(D)(i). 

Section 110(a)(2)(D)(ii) -Interstate and International Pollution Abatement: Section 

11 O(a)(2)(D)(ii) requires states to insure compliance with applicable requirements of 

Sections 126 and 115 (relating to interstate and international pollution abatement). 

Indiana's SIP meets the requirements of Section 11 O(a)(2)(D)(ii), which relates to 

Section 115 and Section 126 of the CAA. With respect to Section 115, Indiana 

has no pending obligations related to international pollution abatement. IDEM's 

SIP-approved PSD rules require that neighboring states be notified of new or 

modified sources, consistent with the requirements of Section 126(a). Finally, 

Indiana has no pending obligations under Section 126(b), which pertains to 

5 
S02 Infrastructure SIP 

State of Indiana 

petitions for finding that major sources emit or would emit prohibited air 

pollutants. 

U.S. EPA issued preliminary designations for Veale Township in Daviess County, 

Center, Perry, and Wayne Townships in Marion County, Clay and Washington 

Townships in Morgan County, Washington Township in Pike County, Fayette, 

Harrison, and Otter Creek Townships in Vigo County, and Wayne Township in 

Wayne County as "nonattainment" for the 2010 S02 1-hour standard on February 

6, 2013. IDEM provided U.S. EPA with a response to the proposed designations 

on March 11 and March 28, 2013 and expect final designations to be issued in 

June 2013 (after this submittal is expected to be made). Under the previous 

1971 standard, five counties (Lake, LaPorte, Marion, Vigo, and Wayne) were 

designated as nonattainment and subsequently redesignated to attainment. 

Section 11 O(a)(2)(E)- Adequate Authority and Resources: Section 11 O(a)(2)(E) 

requires SIPs to provide necessary assurances that the state will have adequate 

personnel, funding, and legal authority under state law to carry out each implementation 

plan, and to provide necessary assurances that the state retains responsibility for 

ensuring adequate implementation of the SIP where the state relies on a local or 

regional government for implementation of any SIP provision. 

IDEM continues to update and implement needed revisions to Indiana's SIP, as 

necessary to meet the NAAQS. The authority to adopt emission standards and 

compliance schedules is found in IC 13-13-8, IC 13-17-3-4, IC 13-17-3-11, and 

IC 13-17-3-14. 

In order to ensure the attainment and maintenance of the 2010 S02 NAAQS, 

IDEM has established emission limitations for sulfur dioxide sources (326 lAC 7-

1.1), as well as compliance requirements (326 lAC 7-2) and ambient monitoring 

requirements (326 lAC 7-3). In addition, emission limitations and requirements 

have been set specifically for Dearborn, Floyd, Gibson, Jefferson, LaPorte, 

Marion, Morgan, Porter, Sullivan, Vermillion, Vigo, Warrick, and Wayne counties 

(326 lAC 7-4), as well as Lake County (326 lAC 7-4.1). 

The budget and personnel plans for IDEM are documented in IDEM's biennial 

budget and the Performance Partnership Grant (PPG) agreement. IDEM does 

not rely on local or regional governments for implementation of SIP provisions. 

In order to satisfy the requirements of Section 11 O(a)(2)(E)(ii), the Indiana 

legislature passed IC 13-13-8 to reflect the formation of a single environmental 

rules board. On November 29, 2012 IDEM submitted an amendment to Indiana's 

SIP requesting U.S. EPA to approve the statutory changes as part of the SIP. 

Notably, the Environmental Rules Board does not act on permit or enforcement 

orders; therefore, only the requirements of Section 128(a)(2) apply. IDEM's 

6 
S02 Infrastructure SIP 

State of Indiana 

Environmental Rules Board is required to fully disclose any potential conflicts of 

interest relating to permits or enforcement orders under the CAA, as found in IC 

13-13-8-11. IDEM requests that the SIP revision submitted on November 29, 

2012, satisfy the applicable requirements of Section 128 of the federal CAA (as 

delineated in that submission) in addition to the applicable infrastructure SIP 

requirements of Section 11 O(a)(2)(E) for the 2010 S02 NAAQS. Lastly, IDEM 

requests that the November 29, 2012, submission satisfy the applicable state 

board requirements of Section 110(a)(2)(E) for any infrastructure SIP for which 

U.S. EPA has not finalized action for this section, e.g., the 2006 PM2.5 NAAQS, 

the 2008 Ozone NAAQS, the 2008 Lead NAAQS, and the 2010 N02 NAAQS. 

Section 11 O(a)(2)(F)- Stationary Source Monitoring System: Section 11 O(a)(2)(F) 

provides that SIPs are to require the installation, maintenance, and replacement of 

equipment and the implementation of other necessary steps by owners or operators of 

stationary sources to monitor emissions from stationary sources. Section 11 O(a)(2)(F) 

also provides that SIPs are to require periodic reports on the nature and amounts of 

emissions and emission-related data from the stationary source, and correlation of the 

reports by the state agency with any emission limitations or standards established; the 

reports shall be available at reasonable times for public inspection. 

IDEM's rules for monitoring requirements are contained in 326 lAC 3 and include 

rules specific to the continuous monitoring of emissions, minimum performance 

and operating specifications, quality assurance requirements, record keeping 

requirements, source sampling procedures, and fuel sampling and analysis 

procedures. Additional emission reporting requirements can be found in 326 lAC 

2-6. Emission reports are available upon request by U.S. EPA or other 

interested parties. 

Section 110(a)(2)(G)- Emergency Power: Section 11 O(a)(2)(G) requires SIPs to 

provide authority to address activities causing imminent and substantial endangerment 

to public health, welfare, or the environment, and to provide for adequate contingency 

plans to implement the emergency episode provisions. 

IDEM's rule in 326 lAC 1-5 establishes air pollution episode levels based on 

concentrations of criteria pollutants. The rule requires that emergency reduction 

plans (ERPs) be submitted to the Commissioner by major air pollution sources. 

The ERPs shall state those actions that will be taken to reduce or eliminate 

emissions of the appropriate air pollutants when each episode level is declared. 

Under IC 13-17-4, IDEM also has the ability to declare an air pollution emergency 

and order all persons causing or contributing to the conditions warranting the air 

pollution emergency to immediately reduce or discontinue the emission of air 

pollutants. 

7 
S02 Infrastructure SIP 

State of Indiana 

Section 11 O(a)(2)(H)- Future SIP Revisions: Section 11 O(a)(2)(H) requires SIPs to 

provide for the revision of the plan from time to time as may be necessary to take 

account of revisions of a national primary or secondary ambient air quality standard or 

the availability of improved or more expeditious methods of attaining the standard, and 

whenever U.S. EPA finds that the plan is substantially inadequate to attain the NAAQS 

which it implements. 

IDEM continues to update and implement needed revisions to Indiana's SIP, as 

necessary, to meet the NAAQS. Authority to adopt emissions standards and 

compliance schedules is found in IC 13-13-8, IC 13-17-3-4, IC 13-17-3-11, and 

IC 13-17-3-14. 

Section 110(a)(2)(J)- Consultation with Government Officials, Public Notification, 

PSD, and Visibility Protection: Section 11 O(a)(2)(J) requires SIPs to provide a 

process for consultation with local governments and Federal Land Managers carrying 

out NAAQS implementation requirements, a process for States to notify the public if 

NAAQS are exceeded in an area, and a process to enhance public awareness of 

measures that can be taken to prevent exceedances. In addition, SIPs are to meet 

applicable requirements of Part C of the CAA related to PSD and visibility. 

IDEM actively participates in the regional planning efforts that include state rule 

developers, representatives from the Federal Land Managers, and other affected 

stakeholders. Additionally, IDEM is an active member of the Lake Michigan Air 

Directors Consortium (LADCO). 

IDEM monitors air quality daily and reports the daily air quality index to the 

interested public and media when necessary. IDEM participates and submits 

information to U.S. EPA's AIRNOW program. Additionally, IDEM maintains 

SmogWatch, an informational tool created by IDEM to share air quality forecasts 

each day. SmogWatch provides daily information about ground-level ozone and 

particulate matter concentration levels, as well as health information and 

monitoring data for seven regions in Indiana. 

As discussed in the section addressing Section 11 O(a)(2)(C), Indiana has a U.S. 

EPA-approved PSD program that is consistent with U.S. EPA's own regulations 

contained in 40 CFR 52.21 and 40 CFR 51.166. 

While there is a visibility protection requirement contained in Section 

11 O(a)(2)(J), consultation with U.S. EPA indicates that these requirements are 

different from the ones set forth in Section 11 O(a)(2)(D)(i)(ll) in that the visibility 

protection requirements of Section 11 O(a)(2)(J) are not "triggered" by the 

promulgation of a new or revised NAAQS. Therefore, the visibility protection 

requirements of Section 11 O(a)(2)(J) are not germane to infrastructure SIPs for 

the 2010 S02 NAAQS. 

8 
S02 Infrastructure SIP 

State of Indiana 

Section 110(a)(2)(K)- Air Quality Modeling/Data: Section 11 O(a)(2)(K) requires SIPs 

to provide for the performance of air quality modeling that U.S. EPA may prescribe for 

the purpose of predicting the effect on ambient air quality of any emissions of any air 

pollutant for which U.S. EPA has established a NAAQS, and, upon request, the 

submission of data related to the air quality modeling to U.S. EPA. 

IDEM reviews the potential impact of major and some minor new sources. 

IDEM's rules regarding air quality modeling are contained in 326 lAC 2-2-4, 326 

lAC 2-2-5, 326 lAC 2-2-6, and 326 lAC 2-2-7. Modeling data are available upon 

request by U.S. EPA or other interested parties. 

Section 110(a)(2)(L)- Permitting Fees: Section 11 O(a)(2)(L) requires the owner or 

operator of each major stationary source to pay to the permitting authority a fee 

sufficient to cover the reasonable costs of reviewing and acting upon any application for 

a permit and, if the owner or operator received a permit for a source, the reasonable 

costs of implementing and enforcing the terms and conditions of any permit, until the fee 

requirement is superseded with respect to the source by U.S. EPA's approval of a fee 

program under Title V of the CAA. 

IDEM continues to implement the approved Title V program, including the 

requirement that major sources pay permit fees. The authority to establish Title 

V permit fees can be found in IC 13-17-8. The requirement to pay fees for Title V 

is found in 326 lAC 2-7-19. All fees that may apply to Title V sources are found 

in 326 lAC 2-1.1-7, which was amended in LSA #07-286 and became effective in 

December 2011. In addition, IDEM is able to collect permitting fees through 326 

lAC 2-1.1-7. Lastly, as ascertained in the discussion surrounding Section 

11 O(a)(2)(E), IDEM retains all the necessary resources and funding to administer 

an air quality management program, including the ability to collect permitting 

fees. 

Section 110(a)(2)(M)- Consultation/Participation by Affected Local Entities: 

Section 110(a)(2)(M) requires SIPs to provide for consultation and participation by local 

political subdivisions affected by the SIP. 

IDEM rulemaking procedures in IC 13-14-9 allow for public participation in the 

SIP development process. IDEM also ensures that the requirements of 40 CFR 

51.102 are satisfied during the SIP development process.
