4 hearing before the Air Pollution Control Board of

5 the State of Indiana regarding preliminary

6 adoption of amendments, 326 IAC 2, Particulate

### Matter 2.5 Microns. This is NSR Rule No. 11-251.

We will now introduce Exhibit 7

-- thank

9 you, Ms. Pedersen

-- the draft rule, into the

10 record of this hearing. Chris, I've got your

11 name down as the person to speak to this.

12

13 MS. PEDERSEN: That is correct.

This rule addresses changes to the Federal

14 NSR Rules concerning Fine Particles, or PM 2 . 5 •



### 15 The NSR program is a preconstruction permitting

16 program that applies when a source is constructed

17 

### or modified. It requires state NSR programs to

18 address any pollutant and its precursors for

19 which there is National Ambient Air Quality

20 Standard.

21 There are four federal rulemakings that we

22 are incorporate

-- or that we're bringing

23 language in, into this rulemaking. On May 16th

### 86

1 of 2008, the PM 2

_5 

### New Source Review

2 

### Implementation Rule was established. It has

3 minimum requirements for state permitting

4 programs related to the 2006 PM 2

_5 

### standard.

5 On October 20th of 2010, the Prevention of

6 Significant Deterioration, or PSD, for PM 2

_5 

### on

7 Increments, Significant Impact Levels, and

8 Significant Monitoring Concentration was issued.

9 These are supplemental requirements to the PM 2

_5



### 10 NSR Implementation Rule.

11 

### Also, November 29th of 2005, there was a

12 Phase 2 Implementation Rule that includes

13 requirements related to NSR and PSD for PM 2

_5 .



### 14 U.S. EPA has revised the PSD regulations by

15 identifying nitrogen oxides as an ozone precursor

16 in attainment and unclassifiable areas, and we

17 needed to change our rules to incorporate that

18 back into our rules.

19 July 20th of 2011, the Deferral for Carbon

20 Dioxide Emissions from Bioenergy and Other

21 Biogenic Sources Under the PSD and Title V

22 

### Programs, that rulemaking was issued. It amends

23 the definition of •subject to regulation• to be

### 1 consistent with the federal regulatory term to

2 delay the effective date of carbon dioxide

3 emissions from these types of sources until

4 July 21st of 2014.

5 

### In addition, we've also made some minor

6 changes for clarification and consistency, which

7 were based on comments that we received during

8 the second comment period.

9 All changes are consistent with the

10 federal requirements and do not impose any

11 requirements beyond what is already in the

12 federal rules. 87

13 IDEM requests that the Board preliminarily

14 adopt this draft rule.

15 

### CHAIRMAN MINER: Thank you,

16 Christine.

SECTION 4. 326 lAC 2-2-1 IS AMENDED TO READ AS FOLLOWS:

326 lAC 2-2-1 Definitions Authority: IC 13-14-8; IC 13-17-3 Affected: IC 13-15; IC 13-17

Sec. I. (a) The defmiti0ns in this section apply throughout this rule.

(b) "Aetna! emissions" means the aetna! rate ofemissions ofa regulated new source review (NSR) pollutant from an emissions unit as determiued iu accordance with the followiug: (I) In general, aetna! emissions as ofa particular date shall equal the average rate, iu tons per year, at which theunit actually emittedthe pollutant duriug a consecutive twenty-four (24) month period precediug the particular date andrepresentative ofnormal source operation. The department shall allow the use ofa different time periodupon a determination that it is more representative ofnormal source operation. Aetna! emissions shall be calculated using the unit's actual operatiug hours, productionrates, and types of materials processed, stored, or combusted during the selected time period. (2) The department maypresume that source-specific allowable emissions for the unit are equivalent to the aetna! emissions ofthe unit. (3) For any emissions unit that has not begun normal operations onthe particular date, aetna! emissions shall equal the potential to emit ofthe unit on that date. (4) The term shall not apply for calculating a significant emissions iucrease under section 2(d) ofthis rule

or for establishiug a PAL under 326 lAC 2-2.4. Instead, subsections (e) and (pp) shall apply for those
purposes.

(c) "Adverse impact onvisibility" means visibility impairment that iuterferes with the management, protection, preservation, or enjoyment ofthe visitor's visual experience ofthe federal Class I area as defmed iu



### 15section 13 ofthis rule. This determination mustbe made on a case-by-case basis taking into account tbe geographic extent, intensity, duration, frequency, and time ofvisibility impairment, and how these factors correlate with: (I) times ofvisitor use ofthe federal Class I area; and (2) the frequency and timing ofnatural conditions that reduce visibility.

(d) "Allowable emissions" means the emissions rate ofa stationary source calculated using the maximum rated capacity ofthe source (unless a source is subject to enforceable permit limits that restrict the operating rate or hours ofoperation, or both) and the most stringent ofthe: (I) applicable standards as set forth in 40 CFRPart 60* and 40 CFRPart 61 *; (2) SIP emissions limitation, including those with a future compliance date; or (3) emissions rate specified as an enforceable permit condition, including those with a future compliance date.



### (e) "Baseline actual emissions" means the rate ofemissions, in 

### tons per year, ofa regulated NSRpollutant,

as determined in accordance with the following: (I) For any existing electric utility steam generating unit, the term means the average rate, in tons peryear, at which the unit actually emitted the pollutant during any consecutive twenty-four (24) monthperiod selected by the owner or operator within the five (5) year period immediately preceding whenthe owner or operator begins actual constmction ofthe project. The commissioner shall allow the use ofa different time period upon a deteJmination that it is more representative ofnormal source operation. The baseline actual emissions shall be determined in accordance with the following: (A) The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions to the extent they are affected bythe project. (B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive twenty-four (24) month period. 

### (C) For a regulated NSRpollutant, when a project involves multiple emissions units, only one (I) consecutive twenty-four (24) month period may be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive twenty-four (24) month period can be used for eachregulated NSRpollutant.

Sec. 

### 1. (a) The defmitions in this section apply throughout this rule.

(b) "Actual emissions" means the actual rate ofemissions ofa regulated NSRpollutant from an emissions nnit as determined in accordance with the following: (I) In general, actual emissions as ofa particular date shall equal the average rate, intons peryear, at which the nnit actually emitted the pollutant during a consecutive twenty-four (24) month period that: 

### 33(A) precedes the particular date; and (B) is representative ofnormal source operation. The connnissioner shall allow the use ofa different time period upon a determination that it is more representative ofnormal source operation. Actual emissions shall be calculated usiog the unit's actual operatiog hours, productionrates, and types ofmaterials processed, stored, or combusted duriog the selected time period. (2) The commissioner maypresume that source-specific allowable emissions for the unit are equivalent to the actual emissions ofthe unit. (3) For any emissions unit that has notbegun normal operations on the particular date, actual emissions shall equal the potential to emit ofthe unit on that date. (4) The term shall not apply for calculatiog a significant emissions iocrease under section 2(c) ofthis rule

or for establishing a PAL under 326 lAC 2-3.4. Instead, subsections (d) aud (kk) shall apply for those
purposes.

(c) "Allowable emissions" means the emissions rate ofa source calculated using the maximumrated capacity ofthe source unless a source is subject to enforceable permit limits thatrestrict the operating rate orhours ofoperation, or both, and the most striogent ofthe followiog: (I) The applicable standards as set forth io 40 CFRPart 60, New Source Performance Standards (NSPS)*, and 40 CFR Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAPS)*. (2) The emissions limitation imposedby any rule io this title, iocluding those with a future compliance date. (3) The emissions rate specified as an enforceable permit condition, iocluding those with a future compliance date.

(d) "Baseline actual emissions" means the rate ofemissions, io tons peryear, ofa regulated NSRpollutant,

as determined as follows: (I) For any existing electric utility steam generatiog unit, the term means the average rate, io tons peryear, at which the unit actually emitted the pollutant duriog any consecutive twenty-four (24) monthperiod selected bythe owner or operator withio the five (5) yearperiod immediately precediog whenthe owner or operatorbegios actual construction ofthe project. The commissioner may allow the use ofa different time periodupon a determioation that it is more representative ofnormal source operation. The baselioe actual emissions shall be determioed io accordance with the following: (A) The average rate shall ioclude fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions to the extent they are affected bythe project. (B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable duriog the consecutive twenty-four (24) monthperiod. (C) For a regulated NSRpollutant, when a project involves multiple emissions units, only one (I) consecutive twenty-four (24) month period may be used to determioe the baselioe actual emissions for the emissions units being changed. A different consecutive twenty-four (24) month period can be used for eachregulated NSRpollutant. (D) The average rate shall notbe based on any consecutive twenty-four (24) month period for 

### which there is inadequate information available for determining annual emissions, in 

### tons per year, aud for adjustiog this amount ifrequired by clause (B). (2) For au existiog emissions unit, other than an electric utility steam generatiog unit, the term means the
average rate, io tons per year, at which the emissions unit actually emitted the pollutant during any consecutive twenty-four (24) month period selected by the owner or operator within the ten (1 0) year period immediately preceding either the date the owner or operator begios actual construction ofthe project

or the date a complete permit application is received by the department for a permit required under 326 lAC 2-3, except that the ten (10) year period shall not ioclude any period earlier than November 15, 1990. The baseline actual emissions shall be determioed io accordance with the following: (A) The average rate shall ioclude fugitive emissions to the extent quantifiable and emissions



### 34associated with start-ups, shutdowns, and malfunctions and to the extent they are affected by the project. (B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive twenty-four (24) month period. (C) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply had the major stationary source beenrequired to comply with the limitations during the consecutive twenty-four (24) monthperiod. However, ifan emission limitation is part ofa maximum achievable control technology standard that the U.S. EPA proposed or promulgated under 40 CFRPart 63*, the baseline actual emissions need only be adjusted ifthe state has applied 

### the emissions reduction to an attainment demonstration or maintenance plan consistent with the requirements ofsection 3(b)(l2) ofthis rule. (D) For a regulated NSRpollutant, when a project involves multiple emissions units, only one (I) consecutive twenty-four (24) monthperiodmustbe used to determine the baseline actual emissions for the emissions units being changed.

Sec. 2. (a) This rule applies to new major stationary sources ormajor modifications constructed in an area designated, as ofthe date ofsubmittal ofa complete application, as nonattainment in 326 lAC 1-4, for a pollutant for which the stationary source or modification is major.

(b) This rule applies to modifications ofmajor stationary sources ofVOC or

### (unless aNOx waiver is in 

### effect) in 

### serious and severe ozone nonattainment areas as follows: (1) A modification ofa major stationary source with a de minimis increase in emissions shall be exempt



### 42from section 3 ofthis rule. (2) A modification having an increase in emissions that is not de minimis to an existing major stationary

sonrce that does not have the potential to emit one hundred (100) tons or more ofVOC or 

### eJ<ides ef nitrogen oxides (unless a NOx waiver is in effect) peryear will notbe subject to section 3(a) ofthis rule if the owner or operator ofthe sonrce elects to internal offset the increase by a ratio ofone and three-tenths (1.3) to one (1). Ifthe owner or operator does not make the election or is unable to, section 3(a) ofthis rule applies, except that BACT shall be substituted for LAERrequired by section 3(a)(2) ofthis rule. (3) A modification having an increase in emissions that is not de minimis to an existing major stationary

sonrce emitting orhaving the potential to emit one hundred (100) tons ofVOC or

### eJ<ides efnitrogen oxides (unless a NOx waiver is in effect) or more peryear will be subject to the requirements ofsection 3(a) of this rule, except that the owner or operator may elect to internal offset the increase at a ratio ofone and three-tenths 

### (1.3) to one 

### (1) as a substitute for LAERrequiredby section 3(a)(2) ofthis rule.

(c) The requirements ofthis rule will be applied in accordance with the following: 

### (1) Except as otherwise provided in subsection (k) and consistent withthe definition ofmajor modification in section l(y) ofthis rule, a project is a major modification for a regulated NSRpollutant ifit causes a 

### significant emissions increase and a significant net emissions increase except for VOC emissions in a

severe or serious nonattainment area for ozone. The project is not a major modification 

### if

### it does not cause

a significant emissions increase. If

### the project causes a significant emissions increase, then the project is a major modification only 

### if

### it also results in 

### a significant net emissions increase. (2) Prior to beginning actual construction, the procedure for calculating whether a sigoificant emissions increase will occnr depends uponthe type ofemissions units being modified, in accordance with this 

### subsection, except for VOC emissions in 

### a severe or serious nonattainment area for ozone. The procedure for calculating, before beginning actual construction, whether a sigoificant net emissions increase will

occur at the major stationary sonrce is contained in section I( cc) ofthis rule. Regardless ofany 

### preconstruction projections, amajor modification results if

### the project causes a significant emissions increase and a significant net emissions increase. (3) For an actual-to-projected-actual applicability test for projects that only involve existing emissions units, a significant emissions increase ofa regulatedNSRpollutant is projected to occnr ifthe sum ofthe difference between the projected actual emissions and the baseline actual emissions for each existing emissions unit equals or exceeds the sigoificant amount for thatpollutant. (4) For an actual-to-potential applicability test for projects that only involve construction ofnew emissions units, a significant emissions increase ofa regulated NSRpollutant is projected to occnr ifthe sum ofthe difference between the potential to emit from each new emissions unit following completion ofthe project and the baseline actual emissions ofthese units before the project equals or exceeds the sigoificant amount for that pollutant. (5) Forprojects that involve a combination ofemission units using the tests in subdivisions (3) and (4), a significant emissions increase ofa regulated NSRpollutant is projected to occur ifthe sum ofthe emissions increases for each emissions unit, using the method specified in subdivisions (3) and (4), as applicable, with 

### respect to each emissions unit, for each type ofemissions unit equals or exceeds the significant amount for
that pollutant.

(d) Atthe time that a particular source ormodification becomes a major stationary somce ormajor modification solely byvirtue ofa relaxation in any enforceable limitation that was established after August 7, 1980,

onthe capacity ofthe source or modification otherwise to emit a pollutant, such as a restriction onhonrs of operation, then this rule applies to the sonrce or modification as though constmction had not yet commenced on the



### source or modification.

(e) Inthe case ofan area that has beenredesigoated nonattainment, any source that would not have been required to submit a permit application under 326 lAC 2-2 concerning the prevention of significant deterioration will notbe subject to this rule ifconstruction commences within eighteen (18) months ofthe area's redesignation.

or 112 ofthe CAA.

(h) For purposes ofthis rule, secondary emissions from a source need notbe considered io determining whether the source would quality as a major source. Ifa source is subject to this rule on the basis ofthe direct


## 44emissions from the source, the applicable conditions must also be met for secondary emissions. The secondary emissions may be exempt fi·om the requirements specified in section 3(a)(2) through 3(a)(3) ofthis rule.

(i) HAPs listed in andregulated by 326 lAC 14-1 are not exempt from this rule.



### G) The installation, operation, cessation, or removal oftemporary clean coal technology demonstration projects fimded under the Department ofEnergy-Clean Coal Technology Appropriations maybe exempt from the requirements ofsection 3 ofthis rule. To qualifY for this exemption, the project must: (I) be at an existing facility; (2) operate for not more than five (5) years; and (3) comply with all other applicable rules for the area.

(k) For any major stationary source operating under a PAL for a regulated NSRpollutant, the major stationary source shall comply with requirements under 326 lAC 2-3 .4.

### projects at existing emissions units at amajor stationary source, other than projects at a source with a PAL, in circumstances where there is a reasonable possibility, within the meaning ofthis subsection, that a projectthat is not

a part ofa major modification may result in a significant emissions increase ofa regulated NSRpollutant, andthe

owner or operator elects to use the method specified in section l(kk)(2)(A) ofthis rule for calculating projected 

### actual emissions: (I) Before beginning actual construction ofthe project, the owner or operator shall document and maintain

a record ofthe following information: (A) A description ofthe project. (B) Identification ofthe emissions units whose emissions ofa regulated NSRpollutant couldbe affected by the project. (C) A description ofthe applicability test used to determine that the project is not a major modification for any regulated NSRpollutant, including the following: (i) The baseline actual emissions.

(iv) Any netting calculations, ifapplicable. (2) lfthe emissions unit is an existing electric utility steam generating unit, before beginning actual construction, the owner or operator shall provide a copy ofthe information set out in subdivision (I) to the department. Nothing in this subdivision shall be construed to require the owner or operator ofthe unit to obtain any determination from the department before beginning actual construction. (3) The owner or operator shall: (A) monitor the emissions ofany regulated NSRpollutant that could increase as a result ofthe project and that is emittedby any emissions units identified in subdivision (l)(B); and (B) calculate and maintain a record ofthe armual emissions, in tons peryear on a calendar year basis, for a period offive (5) years following resumption ofregular operations after the change, or for a period often (I0) years following resumption ofregular operations after the change ifthe project increases the design capacity or potential to emit ofthat regulated NSRpollutant at the 

### emissions unit. (4) Ifthe unit is an existing electric utility steam generating unit, the owner or operator shall submit a report
to the department within sixty (60) days after the end ofeachyear during whichrecords mustbe generated under subdivision (3) setting out the unit's annual emissions during the year that preceded submission ofthe report. (5) Ifthe unit is an existing unit other than an electric utility steam generating unit, the owner or operator shall submit a report to the department ifthe annual emissions, in tons per year, from the project identified in subdivision (1), exceed the baseline actual emissions, as documented and maintained under subdivision (I)(C), by a significant amount for that regulated NSRpollutant, and ifthe emissions differ from the



### 45preconstruction projection as documented and maintained under subdivision (I)(C). The report shall be submitted to the department within sixty (60) days after the end ofthe year. The repmt shall contain the following: (A) The name, address, and telephone number ofthe major stationary source. (B) The annual emissions as calculated under subdivision (3). (C) The emissions calculated under the actual to projected actual test stated in subsection ( c)(3). (D) Any other information that the owner or operator wishes to include inthe report.

to result in either: (A) a projected actual emissions increase ofat least fifty percent (50%) ofthe amount that is a significant emissions increase, as defined in section I(qq) ofthis rule, without reference to the

amount that is a significant net emissions increase, for the regulated NSRpollutant; or (B) a projected actual emissions increase that, added to the amount ofemissions excluded under section 1(kk)(2)(A)(iii), sums to at least fifty percent (50%) ofthe amount that is a significant emissions increase, as defined in section l(qq) ofthis rule, without reference to the amount that is

a significant net emissions increase, for the regulated NSRpollutant. For a project for which a reasonable possibility occurs only within the meaning ofthis clause, and not also within the meaning ofclause (A), then subdivisions (2) through (5) do not apply to the project. (7) The owner or operator ofthe source shall make the information required to be documented and maintained under subdivisions (I) tlu·ough (5) available for review upon a request for inspection by the department. The general public may request this information from the department under 326 lAC 17.1.

326 lAC 2-3-3 Applicable requirements Authority: IC 13-14-8; IC 13-17-3 Affected: IC 13-15; IC 13-17

Sec. 3. (a) Prior to the issuance ofa construction permit to a source subject to this rule, the applicant shall comply withthe following requirements: (I) The proposed major new source ormajor modification shall demonstrate that the source will meet all applicable requirements ofthis title, any applicable new source performance standard in 40 CFRPart 60*,

or any national emission standard for HAPs in 40 CFRPart 61 *. Ifthe commissioner determines that the proposed major new source cannot meet the applicable emission requirements, the permitto construct will be denied. (2) The applicant will apply emission limitation devices or techniques to the proposed construction or modification suchthat the LAERfor the applicable pollutant will be achieved. (3) The applicant shall either demonstrate that: (A) all existing major sources owned or operated by the applicant in the state are in compliance with all applicable emission limitations and standards contained in the CAA and in this title; or (B) they are in compliance with a federally enforceable compliance schedule requiring compliance

as expeditiously as practicable. (4) The applicant shall submit an analysis ofalternative sites, sizes, production processes, and enviromnental control techniques for the proposed source that demonstrates that benefits ofthe proposed

source significantly outweigh the enviromnental and social costs imposed as a result ofits location,



### 46

### constmction, or modification. (5) Emissions resulting from the proposed construction or modification shall be offset by a reduction in actual emissions ofthe same pollutant from an existing source or combination ofexisting sources. The emission offset shall be such that there will be reasonable further progress toward attainment ofthe applicable ambient air quality standards as follows: (A) Greater than one-for-one unless otherwise specified. (B) For ozone nonattainment areas, the following table shall determine the minimum offset ratio requirements for major stationary sources ofVOC or

### eJ<ides efnitrogen oxides (unless a NOx waiver is in effect):

Ozone Classification Marginal Minimum Offset Requirements 

### 1.1 to 

### I
Moderate 1.15 to I 

### Serious 1.2 to 

### I
Severe 

### 1.3 to I

(6) The total tonnage ofincreased emissions, in tons peryear, resulting from a major modification that must be offset in accordance with Section 173 ofthe CAA shall be determined by summingthe difference betweenthe allowable emissions after the modification and the actual emissions before the modification for 

### each emissions unit. (7) The applicant shall obtain the necessary preconstruction approvals and shall meet all the permit requirements specified in 3261AC 2-5.1 or 3261AC 2-7, as applicable. (8) Approval to construct shall notrelieve any owner or operator ofthe responsibility to comply fully with

an applicable provision ofthe SIP and any other requirements under local, state, or federal law.

(b) The following provisions shall apply to all emission offset evaluations: (I) Emission offsets shall be determined on a tons per year and, whenever possible, a pounds perhour basis when all facilities requiring offset involved in the emission offset calculations are operating attheir maximum potential or allowed production rate. When offsets are calculated on a tons peryearbasis, the baseline emissions for existing sources providing the offsets shallbe calculatedusing the allowed or actual annual operating hours, whichever is less. (2) The baseline for determining credit for emission offsets willbe the emission limitations or actual emissions, whichever is lower, in effect atthe time the application to construct or modify a source is filed. Credit for emission offsetpurposes may be allowable for existing control that goes beyondthat required by 

### source-specific emission limitations contained in 

### this title. (3) in cases where the applicable rule under this title does not contain an emissionlimitation for a source or

source category, the emission offset baseline involving the sources shallbe the actual emissions determined

at their maximum expected or allowable productionrate. (4) In cases where emission limitations for existing sources allow greater emissions than the potential to emit ofthe source, emission offset credit shall only be allowed for emissions controlledbelow the potential

to emit. (5) A source may receive offset credit fi·om emission reductions achieved by shutting down an existing

source or permanently curtailing production or operating hours belowbaseline levels ifthe reductions are permanent, quantifiable, and federally enforceable, as follows: (A) Ifthe area has an attainment plan approved by the U.S. EPA, the shutdown or curtailment is creditable only ifit occurred on or after the date ofthe most recent emissions inventory or attainment demonstration. However, inno event may credit be given for shutdowns that occurred prior to August 7, 1977. For purposes ofthis clause, the department may choose to consider a prior shutdown or curtailment to have occurred after the date ofits mostrecent emissions inventory ifthe inventory explicitly includes, as current existing emissions, the emissions from the previously shutdown or curtailed sources. (B) The reductions maybe credited in the absence ofan approved attainment demonstration only ifthe:



## 47(i) shutdown or curtailment occurred on or after the date the new source pennit application is filed; or (ii) applicant can establish that the proposed new source is a replacement for the shutdown or curtailed source and the cutoffdate provisions in clause (A) are observed. (6) Emission offset credit involving an existing fuel combustion source will be based on the allowable emissions under other mles ofthis title for the type offuel being burned at the time tbe new source application is filed. Ifthe existing source commits to switch to a cleaner fuel at some future date, emission offset credit based on the allowable emissions for the fuels involved is acceptable, providedthe permit is conditioned to require the use ofa specific alternative control measure that would achieve the same degree ofemission reduction should the source switch back to a dirtier fuel at some later date. The commissioner will grant emission offset credit for fuel switching only after ensuring that adequate supplies ofthe new fuel are available at least for the next ten 

### (10) years. (7) In the case ofVOC emissions, no emission offset credit maybe allowed for replacing one (1) hydrocarbon compound with another oflesser reactivity, except for those compounds defmed as nonphotochemically reactive hydrocarbons in 326 lAC 1-2-48. (8) No emission reduction may be approved to offset emissions that cannot be federally enforced. Offsetting emissions shall be considered federally enforceable 

### ifthe reduction is included as a condition in the applicable permit as specified in 326 lAC 2-5.1 or 326 lAC 2-7 ifissued nuder a federally-approved air permitprogram. (9) Emission reductions required under any other rule adopted by the board shallnotbe creditable as emission reductions and therefore cannotbe used for emission offsets. (1 0) Incidental emission reductions that are not otherwise required by any otherrule adopted bythe board shall be creditable as emission reductions for emission offsets ifthe emissionreductions meet all ofthe other requirements for offsets. (II) A source may offset by alternative or innovative means emission increases from rocket engine or
motor firing and cleaningrelated to the frring at an existing ormodifred major source that tests rocket engines ormotors nuder the following conditions: (A) Any modification proposed is solely for the purpose ofexpanding the testing ofrocket engines

or motors at an existing source that is permittedto testthe engines onNovember 15, 1990. (B) The source demonstrates to the satisfaction ofthe department that: (i) ithas used allreasonable means to obtain and utilize offsets, as determined on an 

### annual basis, for the emissions increases beyond allowable levels; (ii) all available offsets are being used; and (iii) sufficient offsets are not available to the source. (C) The source has obtained a written frnding from: (i) the Department ofDefense; (ii) the Department ofTransportation; (iii) the National Aeronautics and SpaceAdministration; or (iv) another appropriate federal agency; that the testing ofrocket motors or engines atthe facility is required for a program essential to the 

### national security. (D) The source will comply with an alternative measure, imposed by the department, designed to offset any emission increases beyond permitted levels not directly offset by the source. (12) Credit for an emissions reduction canbe claimed to the extent that the department has notrelied on the 

### emission reduction credit 

### in: (A) issuing any permit nuder regulations approved pursuant to 40 CFR Part 51 Subpart 

### I*; or (B) a demonstration for attaimnent orreasonable further progress.

HISTORY First Notice of Comment Period: May 4, 2011, Indiana Register (DIN: 20110504-IR-326110251FNA). Continuation of First Notice of Comment Period: September 7, 2011, Indiana Register (DIN: 20110907-IR-326110251FCA). Second Notice of Comment Period: December 14, 2011, Indiana Register (DIN: 20111214-IR-326110251SNA). Notice of First Hearing: December 14, 2011, Indiana Register (DIN: 20111214-IR-326110251PHA). Date of First Hearing: February 1, 2012.

PUBLIC COMMENTS UNDER IC 13-14-9-4.5 IC 13-14-9-4.5 states that a board may not adopt a rule under IC 13-14-9 that is substantively different from the draft rule published under IC 13-14-9-4 until the board has conducted a third comment period that is at least 21 days long. Because this proposed rule is not substantively different from the draft rule published on December 14, 2011, at DIN: 20111214-IR-326110251SNA, the Indiana Department of Environmental Management (IDEM) is not requesting additional comment on this proposed rule.

SUMMARY/RESPONSE TO COMMENTS FROM THE SECOND COMMENT PERIOD The Indiana Department of Environmental Management (IDEM) requested public comment from December 14, 2011, through January 13, 2012, on IDEM's draft rule language. IDEM received comments from the following parties: United States Environmental Protection Agency (EPA) Bingham Greenebaum Doll, LLP on behalf of CASE Coalition (CASE) Following is a summary of the comments received and IDEM's responses thereto: Comment: In IDEM's draft rules, the definition of "major source baseline date" (326 IAC 2-2-1 (ee)(1)) says "in the case of PM and sulfur dioxide, January 6, 1975" and the definition of "minor source baseline date" (326 IAC 2- 2-1 (gg)(1)(A)) says "in case of PM and sulfur dioxide, August 7, 1977." However, the Environmental Protection Agency's October 20, 2010 PM2.5 

### PSD final rule (75 FR 64864) made revisions to these definitions in the federal rule. The definition of "major source baseline date" in 40 CFR 51.166(b)(14)(i)(a) was revised to say "in case of PM 10 

### and sulfur dioxide, January 6, 1975." Likewise, the definition of "minor source baseline date" in 40 CFR 51.166(b)(14)(ii)) was revised to say "in case of PM 10 

### and sulfur dioxide, August 7, 1977." We recommend that IDEM revise these definitions to be consistent with the changes to the federal rule. (EPA) Response: IDEM concurs and has made the suggested changes. Comment: A lawsuit has been filed challenging the PM2.5 

### significant impact levels (SILs) and significant monitoring concentration (SMC) that EPA promulgated as part of the October 20, 2010, PM2.5 

### PSD final rule. While Region 5 has no adverse comments on IDEM's adoption of the PM2.5 

### SILs and SMC from the federal rule, the legal challenge may result in a court decision or agency action that could affect the approvability of state submittals such as Indiana's that include the current PM2.5 

### SILs and SMC. Response: IDEM appreciates the information concerning the legal challenge. IDEM proposes to continue forward with the addition of the SILs and SMC to be consistent with the current federal rules. If the legal challenge results in changes to these requirements, IDEM will reconsider the rules and may make changes in a future rulemaking. Comment: The provision at 326 IAC 2-2-1 (ss)(1)(C) should be amended to expressly exclude ammonia as a precursor to PM2.5

### . As proposed, the definition of "regulated NSR pollutant" in 326 IAC 2-3-1 (mm)(3)(C) includes the statement: "VOC and ammonia are not precursors to PM2.5 

### in any PM2.5 

### nonattainment area." However, the definition of "regulated NSR pollutant" in 326 IAC 2-2-1 (ss) only expressly excludes VOC as a precursor to PM2.5

### . Indiana Register

Date: Jul 11,2012 10:45:30AM EDT DIN: 20120229-IR-326110251PRA Page 1

### Expressly excluding both VOC and ammonia as precursors to PM2.5 

### in 326 IAC 2-3, but only expressly excluding

VOC in 326 IAC 2-2 creates an inconsistency that could be misinterpreted. Therefore, 326 IAC 2-2-1 (ss)(1)(C) should be amended to expressly exclude both VOC and ammonia as follows: "VOC and ammonia are not precursors to PM2.5

### ." (CASE) Response: IDEM concurs and has made the suggested change. Comment: CASE Coalition understands that IDEM is considering whether 326 IAC 26-1-6 actually needs to be amended given the scope of the current rule language. However, if 326 IAC 26-1-6(d)(2) is amended, the language should be replaced with "PM 10 

### and direct PM2.5

### " rather than "PM 10 

### and PM2.5

### ." Response: Upon consideration, IDEM recognizes that because PM2.5 is a subset of PM10, it is already included in the calculation for determining whether or not a BART analysis is required. IDEM has determined that no changes are necessary in 326 IAC 26-1-6 and is removing this section from the rulemaking.

### Authority: IC 13-14-8; IC 13-17-3

Affected: IC 13-15; IC 13-17

Sec. 1. (a) The definitions in this section apply throughout this rule.

(b) "Actual emissions" means the actual rate of emissions of a regulated new source review (NSR) pollutant from an emissions unit as determined in accordance with the following: (1) In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a consecutive twenty-four (24) month period preceding the particular date and representative of normal source operation. The department shall allow the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period. (2) The department may presume that source-specific allowable emissions for the unit are equivalent to the actual emissions of the unit. (3) For any emissions unit that has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the unit on that date. (4) The term shall not apply for calculating a significant emissions increase under section 2(d) of this rule or for establishing a PAL under 326 IAC 2-2.4. Instead, subsections (e) and (pp) shall apply for those purposes.

(c) "Adverse impact on visibility" means visibility impairment that interferes with the management, protection, preservation, or enjoyment of the visitor's visual experience of the federal Class I area as defined in section 13 of this rule. This determination must be made on a case-by-case basis taking into account the geographic extent, intensity, duration, frequency, and time of visibility impairment, and how these factors correlate with: (1) times of visitor use of the federal Class I area; and (2) the frequency and timing of natural conditions that reduce visibility.

(d) "Allowable emissions" means the emissions rate of a stationary source calculated using the maximum rated capacity of the source (unless a source is subject to enforceable permit limits that restrict the operating rate or hours of operation, or both) and the most stringent of the: (1) applicable standards as set forth in 40 CFR Part 60* and 40 CFR Part 61*; (2) SIP emissions limitation, including those with a future compliance date; or (3) emissions rate specified as an enforceable permit condition, including those with a future compliance date.

(e) "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with the following: (1) For any existing electric utility steam generating unit, the term means the average rate, in tons per year, at which the unit actually emitted the pollutant during any consecutive twenty-four (24) month period selected by the owner or operator within the five (5) year period immediately preceding when the owner or operator begins actual construction of the project. The commissioner shall allow the use of a different time period upon a determination that it is more representative of normal source operation. The baseline actual emissions shall be determined in accordance with the following: (A) The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions to the extent they are affected by the project. (B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive twenty-four (24) month period. (C) For a regulated NSR pollutant, when a project involves multiple emissions units, only one (1) consecutive twenty-four (24) month period may be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive twenty-four (24) month period can be used for each regulated NSR pollutant. (D) The average rate shall not be based on any consecutive twenty-four (24) month period for which there is inadequate information available for determining annual emissions, in tons per year, and for adjusting this amount if required by clause (B). (2) For an existing emissions unit other than an electric utility steam generating unit, the term means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive twenty-four (24) month period selected by the owner or operator within the ten (10) year period immediately preceding either the date the owner or operator begins actual construction of the project or the Indiana Register

### date a complete permit application is received by the department for a permit required by this rule, except that

the ten (10) year period shall not include any period earlier than November 15, 1990. The baseline actual emissions shall be determined in accordance with the following: (A) The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions to the extent they are affected by the project. (B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive twenty-four (24) month period. (C) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply had the major stationary source been required to comply with the limitations during the consecutive twenty-four (24) month period. However, if an emission limitation is part of a maximum achievable control technology standard that the U.S. EPA proposed or promulgated under 40 CFR Part 63*, the baseline actual emissions need only be adjusted if the department has applied the emissions reductions to an attainment demonstration or maintenance plan consistent with the requirements of 326 IAC 2-3-3(b)(12). (D) For a regulated NSR pollutant, when a project involves multiple emissions units, only one (1) consecutive twenty-four (24) month period may be used to determine the baseline actual emissions for all the emissions units being changed. A different consecutive twenty-four (24) month period can be used for each regulated NSR pollutant. (E) The average rate shall not be based on any consecutive twenty-four (24) month period for which there is inadequate information available for determining annual emissions, in tons per year, and for adjusting this amount if required by clauses (B) and (C). (3) For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of the unit shall equal zero (0) and thereafter, for all other purposes, shall equal the unit's potential to emit. (4) For a PAL for a stationary source, the baseline actual emissions shall be calculated as follows: (A) For an existing electric utility steam generating unit, in accordance with subdivision (1). (B) For an existing emissions unit except an existing electric utility steam generating unit, in accordance with subdivision (2). (C) For a new emissions unit, in accordance with subdivision (3).

(f) "Baseline area" means the following: (1) Any intrastate area (and every part thereof) designated as attainment or unclassifiable in accordance with 326 IAC 1-4 in which the major stationary source or major modification establishing the minor source baseline date would construct or would have an air quality impact for the pollutant for which the baseline date is established: (A) equal to or greater than one (1) microgram per cubic meter (μg/m3

In no event shall application of BACT result in emissions of any pollutant that would exceed the emissions allowed by any applicable standard under 40 CFR Part 60* and 40 CFR Part 61*. If the commissioner determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard not feasible, a design, equipment, work practice, operational standard, or combination thereof may be prescribed instead to satisfy the requirements for the application of BACT. The standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of the design, equipment, work practice, or operation and shall provide for compliance by means that achieve equivalent results.

326 IAC 2-2-14 Sources impacting federal Class I areas: additional requirements Authority: IC 13-14-8; IC 13-17-3 Affected: IC 13-15; IC 13-17

Sec. 14. (a) The department shall provide written notice of any permit application for a proposed major stationary source or major modification, the emissions from which may affect a Class I area, to the federal land manager and the federal official charged with direct responsibility for management of any lands within any such the Class I area. Such The notification shall be given within thirty (30) days of receipt of a permit application and at least sixty (60) days prior to any public hearing on the application for a permit to construct and shall include the following: (1) A copy of all information relevant to the permit application. (2) An analysis of the proposed source's anticipated impacts on visibility in the federal Class I area. The department shall also provide the federal land manager and such the federal officials with a copy of the preliminary determination required under this section, and shall make available to them any materials used in making that determination, promptly after the department makes the determination. The department shall also notify all affected federal land managers within thirty (30) days of receipt of any advance notification of any such permit application that may affect a Class I area

.

(b) The federal land manager and the federal official charged with direct responsibility for management of the Class I area have an affirmative responsibility to protect the air quality related values, including visibility, of the Class I area and to consider, in consultation with U.S. EPA, whether a proposed source or modification will have an adverse impact on such the values.

(c) The department shall consider any analysis performed by the federal land manager, provided to the department within thirty (30) days of the notification required by subsection (a), that shows that a proposed new major stationary source or major modification may have an adverse impact on visibility in any federal Class I area. Where the department finds that the analysis does not demonstrate to the satisfaction of the department that an adverse impact on visibility will result in the federal Class I area, the department must, in the notice of public hearing on the permit application, either explain the decision or give notice as to where the explanation may be obtained.

(d) The federal land manager of any Class I area may demonstrate to the department that the emissions from a proposed major stationary source or major modification would have an adverse impact on the air quality-related values, including visibility, of a Class I area, notwithstanding that the change in air quality resulting from emissions from the major stationary source or major modification would not cause or contribute to concentrations that would exceed the maximum allowable increases for a Class I area. If the department concurs with the demonstration, then the department shall not issue the permit. Indiana Register

### (e) The owner or operator of a proposed major stationary source or major modification may demonstrate to the

federal land manager that the emissions from the source or modification would have no adverse impact on the air quality related values of any Class I areas, including visibility, notwithstanding that the change in air quality resulting from emissions from the major stationary source or major modification would cause or contribute to concentrations that would exceed the maximum allowable increases for a Class I area. If the federal land manager concurs with the demonstration and the federal land manager so certifies, the department may issue the permit provided that the applicable requirements of this section are otherwise met, to issue the permit with emission limitations as may be necessary to assure that emissions of sulfur dioxide, particulate matter, PM, and nitrogen oxides shall not exceed the following maximum allowable increases over minor source baseline concentration for such pollutants:

(f) The owner or operator of a proposed major stationary source or major modification that cannot be approved under subsection (e) may demonstrate to the department that the source cannot be constructed by reason of any maximum allowable increase for sulfur dioxide for a period of twenty-four (24) hours or less applicable to any Class I area and, in the case of federal mandatory Class I areas, that an exemption under this subsection would not adversely affect the air quality related values of the area, including visibility. The department, after consideration of the federal land manager's recommendation, if any, and subject to the federal land manager's concurrence, may, after notice and public hearing, grant an exemption from such the maximum allowable increase. If such the exemption is granted, the department shall issue a permit to such the major stationary source or major modification pursuant to the requirements under subsection (h) provided that the applicable requirements of this section are otherwise met.

(g) In any case where the department recommends an exemption in which the federal land manager does not concur, the recommendations of the department and the federal land manager shall be transmitted to the President. The President may approve the department's recommendation if the President finds that the exemption is in the national interest. If the exemption is approved, the department shall issue a permit pursuant to the requirements under subsection (h) provided that the applicable requirements of this section are otherwise met.

(h) In the case of a permit issued pursuant to under subsection (f) or (g), the major stationary source or major modification shall comply with such the emission limitations as may be necessary to assure that emissions of sulfur dioxide from the major stationary source or major modification would not, during any day on which the otherwise applicable maximum allowable increases are exceeded, cause or contribute to concentrations that would exceed the following maximum allowable increases over the baseline concentration and to assure that such the emissions would not cause or contribute to concentrations that exceed the otherwise applicable maximum allowable increases for periods of exposure of twenty-four (24) hours or less for more than eighteen (18) days, not necessarily consecutive, during any annual period:

SECTION 8. 326 IAC 2-3-1 IS AMENDED TO READ AS FOLLOWS:

326 IAC 2-3-1 Definitions Authority: IC 13-14-8; IC 13-17-3 Affected: IC 13-15; IC 13-17

Sec. 1. (a) The definitions in this section apply throughout this rule.

(b) "Actual emissions" means the actual rate of emissions of a regulated NSR pollutant from an emissions unit as determined in accordance with the following: (1) In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a consecutive twenty-four (24) month period that: (A) precedes the particular date; and (B) is representative of normal source operation. The commissioner shall allow the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period. (2) The commissioner may presume that source-specific allowable emissions for the unit are equivalent to the actual emissions of the unit. (3) For any emissions unit that has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the unit on that date. (4) The term shall not apply for calculating a significant emissions increase under section 2(c) of this rule or for establishing a PAL under 326 IAC 2-3.4. Instead, subsections (d) and (kk) shall apply for those purposes.

(c) "Allowable emissions" means the emissions rate of a source calculated using the maximum rated capacity of the source unless a source is subject to enforceable permit limits that restrict the operating rate or hours of operation, or both, and the most stringent of the following: (1) The applicable standards as set forth in 40 CFR Part 60, New Source Performance Standards (NSPS)*, and 40 CFR Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAPS)*. (2) The emissions limitation imposed by any rule in this title, including those with a future compliance date. (3) The emissions rate specified as an enforceable permit condition, including those with a future compliance date.

(d) "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined as follows: (1) For any existing electric utility steam generating unit, the term means the average rate, in tons per year, at which the unit actually emitted the pollutant during any consecutive twenty-four (24) month period selected by Indiana Register

Date: Jul 11,2012 10:45:30AM EDT DIN: 20120229-IR-326110251PRA Page 30

### the owner or operator within the five (5) year period immediately preceding when the owner or operator begins

actual construction of the project. The commissioner may allow the use of a different time period upon a determination that it is more representative of normal source operation. The baseline actual emissions shall be determined in accordance with the following: (A) The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions to the extent they are affected by the project. (B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive twenty-four (24) month period. (C) For a regulated NSR pollutant, when a project involves multiple emissions units, only one (1) consecutive twenty-four (24) month period may be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive twenty-four (24) month period can be used for each regulated NSR pollutant. (D) The average rate shall not be based on any consecutive twenty-four (24) month period for which there is inadequate information available for determining annual emissions, in tons per year, and for adjusting this amount if required by clause (B). (2) For an existing emissions unit, other than an electric utility steam generating unit, the term means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive twenty-four (24) month period selected by the owner or operator within the ten (10) year period immediately preceding either the date the owner or operator begins actual construction of the project or the date a complete permit application is received by the department for a permit required under 326 IAC 2-3

, except that the ten (10) year period shall not include any period earlier than November 15, 1990. The baseline actual emissions shall be determined in accordance with the following: (A) The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions and to the extent they are affected by the project. (B) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive twenty-four (24) month period. (C) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply had the major stationary source been required to comply with the limitations during the consecutive twenty-four (24) month period. However, if an emission limitation is part of a maximum achievable control technology standard that the U.S. EPA proposed or promulgated under 40 CFR Part 63*, the baseline actual emissions need only be adjusted if the state has applied the emissions reduction to an attainment demonstration or maintenance plan consistent with the requirements of section 3(b)(12) of this rule. (D) For a regulated NSR pollutant, when a project involves multiple emissions units, only one (1) consecutive twenty-four (24) month period must be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive twenty-four (24) month period can be used for each regulated NSR pollutant. (E) The average rate shall not be based on any consecutive twenty-four (24) month period for which there is inadequate information available for determining annual emissions, in tons per year, and for adjusting this amount if required by clauses (B) and (C). (3) For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of the unit shall equal zero (0) and thereafter, for all other purposes, shall equal the unit's potential to emit. (4) For a PAL for a major stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in subdivision (1), for other existing emissions units in accordance with the procedures contained in subdivision (2), and for a new emissions unit in accordance with the procedures contained in subdivision (3).

(e) "Begin actual construction" means, in general, initiation of physical on-site construction activities on an emissions unit that are of a permanent nature. These activities include, but are not limited to, the following: (1) Installation of building supports and foundations. (2) Laying underground pipework. (3) Construction of permanent storage structures. With respect to a change in method of operations, the term refers to those on-site activities, other than preparatory activities, that mark the initiation of the change.

(f) "Best available control technology" or "BACT" means an emissions limitation, including a visible emission standard, based on the maximum degree of reduction for each regulated NSR pollutant that would be emitted Indiana Register

### from any proposed major stationary source or major modification that the commissioner, on a case-by-case basis,

taking into account energy, environmental, and economic impacts and other costs, determines is achievable for the source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of the pollutant. In no event shall application of BACT result in emissions of any pollutant that would exceed the emissions allowed by any applicable standard under 40 CFR Part 60* or 40 CFR Part 61*. If the commissioner determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard, or combination thereof may be prescribed instead to satisfy the requirement for the application of BACT. The standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of the design, equipment, work practice, or operation and shall provide for compliance by means that achieve equivalent results.

The federal contribution for a qualifying project shall be at least twenty percent (20%) of the total cost of the demonstration project.

(j) "Commence", as applied to construction of a major stationary source or major modification, means that the owner or operator has all necessary preconstruction approvals or permits and either has: (1) begun, or caused to begin, a continuous program of actual on-site construction of the source to be completed within a reasonable time; or (2) entered into binding agreements or contractual obligations, which cannot be canceled or modified without substantial loss to the owner or operator, to undertake a program of actual construction of the source to be completed within a reasonable time.

(k) "Complete", in reference to an application for a permit, means that the application contains all of the information necessary for processing the application. Designating an application complete for purposes of permit processing does not preclude the commissioner from requesting or accepting additional information.

(l) "Construction" means any physical change or change in the method of operation, including: (1) fabrication; (2) erection; (3) installation; (4) demolition; or (5) modification; of an emissions unit, that would result in a change in actual emissions.

SECTION 9. 326 IAC 2-3-2 IS AMENDED TO READ AS FOLLOWS:

326 IAC 2-3-2 Applicability Authority: IC 13-14-8; IC 13-17-3 Affected: IC 13-15; IC 13-17

Sec. 2. (a) This rule applies to new major stationary sources or major modifications constructed in an area designated, as of the date of submittal of a complete application, as nonattainment in 326 IAC 1-4, for a pollutant for which the stationary source or modification is major.

(b) This rule applies to modifications of major stationary sources of VOC or oxides of nitrogen oxides (unless a NOX 

### waiver is in effect) in serious and severe ozone nonattainment areas as follows: (1) A modification of a major stationary source with a de minimis increase in emissions shall be exempt from section 3 of this rule. (2) A modification having an increase in emissions that is not de minimis to an existing major stationary source that does not have the potential to emit one hundred (100) tons or more of VOC or oxides of nitrogen oxides (unless a NOX 

### waiver is in effect) per year will not be subject to section 3(a) of this rule if the owner or operator of the source elects to internal offset the increase by a ratio of one and three-tenths (1.3) to one (1). If the owner or operator does not make the election or is unable to, section 3(a) of this rule applies, except that BACT shall be substituted for LAER required by section 3(a)(2) of this rule. (3) A modification having an increase in emissions that is not de minimis to an existing major stationary source emitting or having the potential to emit one hundred (100) tons of VOC or oxides of nitrogen oxides (unless a NOX 

### waiver is in effect) or more per year will be subject to the requirements of section 3(a) of this rule, except that the owner or operator may elect to internal offset the increase at a ratio of one and three-tenths (1.3) to one (1) as a substitute for LAER required by section 3(a)(2) of this rule.

(c) The requirements of this rule will be applied in accordance with the following: (1) Except as otherwise provided in subsection (k) and consistent with the definition of major modification in section 1(y) of this rule, a project is a major modification for a regulated NSR pollutant if it causes a significant emissions increase and a significant net emissions increase except for VOC emissions in a severe or serious nonattainment area for ozone. The project is not a major modification if it does not cause a significant emissions increase. If the project causes a significant emissions increase, then the project is a major Indiana Register

Date: Jul 11,2012 10:45:30AM EDT DIN: 20120229-IR-326110251PRA Page 38

### modification only if it also results in a significant net emissions increase.

(2) Prior to beginning actual construction, the procedure for calculating whether a significant emissions increase will occur depends upon the type of emissions units being modified, in accordance with this subsection, except for VOC emissions in a severe or serious nonattainment area for ozone. The procedure for calculating, before beginning actual construction, whether a significant net emissions increase will occur at the major stationary source is contained in section 1(cc) of this rule. Regardless of any preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase. (3) For an actual-to-projected-actual applicability test for projects that only involve existing emissions units, a significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the projected actual emissions and the baseline actual emissions for each existing emissions unit equals or exceeds the significant amount for that pollutant. (4) For an actual-to-potential applicability test for projects that only involve construction of new emissions units, a significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the potential to emit from each new emissions unit following completion of the project and the baseline actual emissions of these units before the project equals or exceeds the significant amount for that pollutant. (5) For projects that involve a combination of emission units using the tests in subdivisions (3) and (4), a significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the emissions increases for each emissions unit, using the method specified in subdivisions (3) and (4), as applicable, with respect to each emissions unit, for each type of emissions unit equals or exceeds the significant amount for that pollutant.

(d) At the time that a particular source or modification becomes a major stationary source or major modification solely by virtue of a relaxation in any enforceable limitation that was established after August 7, 1980, on the capacity of the source or modification otherwise to emit a pollutant, such as a restriction on hours of operation, then this rule applies to the source or modification as though construction had not yet commenced on the source or modification.

(e) In the case of an area that has been redesignated nonattainment, any source that would not have been required to submit a permit application under 326 IAC 2-2 concerning the prevention of significant deterioration will not be subject to this rule if construction commences within eighteen (18) months of the area's redesignation.

(f) Major stationary sources or major modifications that would locate in any area designated as attainment or unclassifiable in the state and would exceed the following significant impact levels at any locality, for any pollutant that is designated as nonattainment, must meet the requirements specified in section 3(a)(1) through 3(a)(3) of this rule.

(27) Any other stationary source category that, as of August 7, 1980, is being regulated under Section 111 or 112 of the CAA.

(h) For purposes of this rule, secondary emissions from a source need not be considered in determining whether the source would qualify as a major source. If a source is subject to this rule on the basis of the direct emissions from the source, the applicable conditions must also be met for secondary emissions. The secondary emissions may be exempt from the requirements specified in section 3(a)(2) through 3(a)(3) of this rule.

(i) HAPs listed in and regulated by 326 IAC 14-1 are not exempt from this rule.

(j) The installation, operation, cessation, or removal of temporary clean coal technology demonstration projects funded under the Department of Energy-Clean Coal Technology Appropriations may be exempt from the requirements of section 3 of this rule. To qualify for this exemption, the project must: (1) be at an existing facility; (2) operate for not more than five (5) years; and (3) comply with all other applicable rules for the area.

(3) The owner or operator shall: (A) monitor the emissions of any regulated NSR pollutant that could increase as a result of the project and that is emitted by any emissions units identified in subdivision (1)(B); and (B) calculate and maintain a record of the annual emissions, in tons per year on a calendar year basis, for a period of five (5) years following resumption of regular operations after the change, or for a period of ten (10) years following resumption of regular operations after the change if the project increases the design capacity or potential to emit of that regulated NSR pollutant at the emissions unit. (4) If the unit is an existing electric utility steam generating unit, the owner or operator shall submit a report to the department within sixty (60) days after the end of each year during which records must be generated under subdivision (3) setting out the unit's annual emissions during the year that preceded submission of the report. (5) If the unit is an existing unit other than an electric utility steam generating unit, the owner or operator shall submit a report to the department if the annual emissions, in tons per year, from the project identified in subdivision (1), exceed the baseline actual emissions, as documented and maintained under subdivision (1)(C), by a significant amount for that regulated NSR pollutant, and if the emissions differ from the preconstruction projection as documented and maintained under subdivision (1)(C). The report shall be submitted to the department within sixty (60) days after the end of the year. The report shall contain the following: (A) The name, address, and telephone number of the major stationary source. (B) The annual emissions as calculated under subdivision (3). (C) The emissions calculated under the actual to projected actual test stated in subsection (c)(3). (D) Any other information that the owner or operator wishes to include in the report.

### Sec. 3. (a) Prior to the issuance of a construction permit to a source subject to this rule, the applicant shall

comply with the following requirements: (1) The proposed major new source or major modification shall demonstrate that the source will meet all applicable requirements of this title, any applicable new source performance standard in 40 CFR Part 60*, or any national emission standard for HAPs in 40 CFR Part 61*. If the commissioner determines that the proposed major new source cannot meet the applicable emission requirements, the permit to construct will be denied. (2) The applicant will apply emission limitation devices or techniques to the proposed construction or modification such that the LAER for the applicable pollutant will be achieved. (3) The applicant shall either demonstrate that: (A) all existing major sources owned or operated by the applicant in the state are in compliance with all applicable emission limitations and standards contained in the CAA and in this title; or (B) they are in compliance with a federally enforceable compliance schedule requiring compliance as expeditiously as practicable. (4) The applicant shall submit an analysis of alternative sites, sizes, production processes, and environmental control techniques for the proposed source that demonstrates that benefits of the proposed source significantly outweigh the environmental and social costs imposed as a result of its location, construction, or modification. (5) Emissions resulting from the proposed construction or modification shall be offset by a reduction in actual emissions of the same pollutant from an existing source or combination of existing sources. The emission offset shall be such that there will be reasonable further progress toward attainment of the applicable ambient air quality standards as follows: (A) Greater than one-for-one unless otherwise specified. (B) For ozone nonattainment areas, the following table shall determine the minimum offset ratio requirements for major stationary sources of VOC or oxides of nitrogen oxides (unless a NOX 

### waiver is in effect): Ozone Classification Minimum Offset Requirements

Marginal 1.1 to 1 Moderate 1.15 to 1 Serious 1.2 to 1 Severe 1.3 to 1 (6) The total tonnage of increased emissions, in tons per year, resulting from a major modification that must be offset in accordance with Section 173 of the CAA shall be determined by summing the difference between the allowable emissions after the modification and the actual emissions before the modification for each emissions unit. (7) The applicant shall obtain the necessary preconstruction approvals and shall meet all the permit requirements specified in 326 IAC 2-5.1 or 326 IAC 2-7, as applicable. (8) Approval to construct shall not relieve any owner or operator of the responsibility to comply fully with an applicable provision of the SIP and any other requirements under local, state, or federal law.

(b) The following provisions shall apply to all emission offset evaluations: (1) Emission offsets shall be determined on a tons per year and, whenever possible, a pounds per hour basis when all facilities requiring offset involved in the emission offset calculations are operating at their maximum potential or allowed production rate. When offsets are calculated on a tons per year basis, the baseline emissions for existing sources providing the offsets shall be calculated using the allowed or actual annual operating hours, whichever is less. (2) The baseline for determining credit for emission offsets will be the emission limitations or actual emissions, whichever is lower, in effect at the time the application to construct or modify a source is filed. Credit for emission offset purposes may be allowable for existing control that goes beyond that required by source-specific emission limitations contained in this title. (3) In cases where the applicable rule under this title does not contain an emission limitation for a source or source category, the emission offset baseline involving the sources shall be the actual emissions determined at their maximum expected or allowable production rate. (4) In cases where emission limitations for existing sources allow greater emissions than the potential to emit of the source, emission offset credit shall only be allowed for emissions controlled below the potential to emit. (5) A source may receive offset credit from emission reductions achieved by shutting down an existing source or permanently curtailing production or operating hours below baseline levels if the reductions are permanent, quantifiable, and federally enforceable, as follows: (A) If the area has an attainment plan approved by the U.S. EPA, the shutdown or curtailment is creditable Indiana Register

Date: Jul 11,2012 10:45:30AM EDT DIN: 20120229-IR-326110251PRA Page 42

### only if it occurred on or after the date of the most recent emissions inventory or attainment demonstration.

However, in no event may credit be given for shutdowns that occurred prior to August 7, 1977. For purposes of this clause, the department may choose to consider a prior shutdown or curtailment to have occurred after the date of its most recent emissions inventory if the inventory explicitly includes, as current existing emissions, the emissions from the previously shutdown or curtailed sources. (B) The reductions may be credited in the absence of an approved attainment demonstration only if the: (i) shutdown or curtailment occurred on or after the date the new source permit application is filed; or (ii) applicant can establish that the proposed new source is a replacement for the shutdown or curtailed source and the cutoff date provisions in clause (A) are observed. (6) Emission offset credit involving an existing fuel combustion source will be based on the allowable emissions under other rules of this title for the type of fuel being burned at the time the new source application is filed. If the existing source commits to switch to a cleaner fuel at some future date, emission offset credit based on the allowable emissions for the fuels involved is acceptable, provided the permit is conditioned to require the use of a specific alternative control measure that would achieve the same degree of emission reduction should the source switch back to a dirtier fuel at some later date. The commissioner will grant emission offset credit for fuel switching only after ensuring that adequate supplies of the new fuel are available at least for the next ten (10) years. (7) In the case of VOC emissions, no emission offset credit may be allowed for replacing one (1) hydrocarbon compound with another of lesser reactivity, except for those compounds defined as nonphotochemically reactive hydrocarbons in 326 IAC 1-2-48

. (8) No emission reduction may be approved to offset emissions that cannot be federally enforced. Offsetting emissions shall be considered federally enforceable if the reduction is included as a condition in the applicable permit as specified in 326 IAC 2-5.1 or 326 IAC 2-7 if issued under a federally-approved air permit program. (9) Emission reductions required under any other rule adopted by the board shall not be creditable as emission reductions and therefore cannot be used for emission offsets. (10) Incidental emission reductions that are not otherwise required by any other rule adopted by the board shall be creditable as emission reductions for emission offsets if the emission reductions meet all of the other requirements for offsets.

. (2) The alternative opacity limit shall be based upon a series of three (3) complete mass emission tests (nine (9) sample runs) conducted according to the procedures specified in 326 IAC 3 and three (3) opacity tests conducted simultaneously, according to section 4 of this rule. Where the commissioner determines there is no acceptable test method available, a request for an alternative opacity limit shall be denied. (3) The performance tests must be witnessed by the commissioner, U.S. EPA, the local air pollution control agency, or their authorized representatives unless other arrangements are made in advance of the start of the testing that will allow the testing to proceed without agency staff present to observe the tests. (4) The owner or operator must demonstrate that the following conditions were met during the performance test: (A) The source or emissions unit was operated according to its permitted conditions and under normal or representative operating conditions. (B) The associated air pollution control system was installed and was being operated as specified in any applicable permit condition or conditions. (C) The air pollution control equipment was: (i) properly maintained and in good operating condition; and was (ii) operated according to the manufacturer's recommended operating conditions to minimize emissions and opacity. (D) The affected emissions unit and associated air pollution control equipment were incapable of being adjusted or operated to meet the applicable opacity limit, except during: (i) periods when the control equipment is not operating properly; or (ii) other exempt periods under section 3 of this rule. (E) Each test was conducted under reasonably similar operating conditions. (F) Any other conditions as required by the commissioner or the U.S. EPA.

. (B) Monitoring sufficient to demonstrate compliance with the alternative opacity limit. (C) Regular reporting to verify compliance with the alternative opacity limit. (6) The alternative opacity limit shall only apply to the emissions unit for which the alternative opacity limit was originally established and shall not be extended to any other unit or units. (7) For multiple units or processes with a common stack, all units must be in operation during the entire test series unless operational limitations are specified in the operation permit or simultaneous operation does not conform with the source's operating procedures. (8) The alternative opacity limit shall be determined based on the results of the performance tests. (9) The particulate matter test results for each sample run must demonstrate compliance with all applicable particulate matter limits or standards. If noncompliance is demonstrated during any sample run, the test series is not valid for an alternative opacity limit determination. (10) The alternative opacity limit established for a source shall be incorporated by amendment into the source's operating permit and submitted to the U.S. EPA in accordance with section 7 of this rule. (11) If the alternative opacity limit exceeds an applicable new source performance standard (NSPS) opacity limit, the provisions in 40 CFR 60.11* must be satisfied in addition to the procedures in this rule. The procedures shall be approved by the U.S. EPA, the commissioner, and the local air pollution control agency as appropriate.

(c) Nothing in this rule shall be construed as allowing an exception or exemption from a requirement in a state or federal new source performance standard without approval by the U.S. EPA.
