Dear Ms. Hedman: July 23, 2014



### Re: State Implementation Plan Submittal for Indiana Regarding 326 lAC 26-2-2, Alcoa Best Available Retrofit Technology; LSA #13-503

Pursuant to Section 110 ofthe Clean Air Act and Title 13 ofthe Indiana Code, the Indiana Department ofEnvironmental Management (IDEM) submits an amendment to the Indiana state implementation plan. This amendment consists ofrevisions to 326 lAC 26-2-2 accomplished through one rulemaking. IDEM requests that the United States Environmental Protection Agency (U.S. EPA) approve 326 lAC 26-2-2. This rule makes a conectionto rule language for Wanick Power Station at Alcoa Power Generating Inc., located inNewburgh, Indiana, in the Best Available Retrofit Technology (BART) provisions in 326 lAC 26-2-2. Alcoa submitted an engineering analysis as part ofthe original BART rulemaking that included recommended limits for patiiculate matter (PM), sulfur dioxide (S02) 

### and nitrogen oxides (NOx). For Boilers 2 and 3, the averaging period for the NOx limit was inadvertently submitted as a rolling average instead ofa daily average. All other BART emission limits are in the fmm ofa 24-hour daily average, and the 24-hour rolling average for NOx cunently in this section ofthe rule is incmTect. The BART analysis is independent ofaveraging. On April30, 201.3, Alcoarequested that IDEM revise the rule to correct the mistake in 326 lAC 26-2-2(2)(C)(i). · This submittal consists ofone (1) hard copy ofthe required documentation. An electronic vei'sion ofthe submittal in PDF fmmat that is identical to the hard copy has been sent to Chris Panos at the U.S. EPA Region 5 office. In order to assist with your review ofthis state implementation plan submission, a list ofsuppmiing documents is attached. Throughout the development ofthese amendments to the existing rule, staffofthe Office ofAir Quality worked closely with your staffto ensure that any potential problems that might exist with this requested state implementation planrevision would be resolved. I request that

### KksIndiana Register TITLE 326 AIR POLLUTION CONTROL DIVISION FINDINGS AND DETERMINATION OF THE COMMISSIONER PURSUANT TO IC 13-14-9-8 AND DRAFT RULE LSA Document #13-503 ALCOA BEST AVAILABLE RETROFIT TECHNOLOGY CORRECTION PURPOSE OF NOTICE The Indiana Department of Environmental Management (IDEM) has developed draft rule language for amendments to 326 lAC 26-2-2 concerning a correction to the Best Available Retrofit Technology (BART) requirements for Alcoa Power Generating Inc. (APGI), Warrick Power Station. Additionally, administrative corrections are proposed. IDEM is soliciting written comment on the draft rule language and will schedule a public hearing before the Environmental Rules Board for consideration of adoption ofthese rules. CITATIONS AFFECTED: 326 lAC 26-2-2. AUTHORITY: IC 13-14-8; IC 13-14-9; IC 13-17-3-4; IC 13-17-3-11. STATUTORY REQUIREMENTS IC 13-14-9-8 recognizes that, under certain circumstances, it may be appropriate to reduce the number of public comment periods and public hearings usually provided for underthe IC 13-14-9 environmental rulemaking process. In cases where the commissioner determines that there is no reasonably anticipated benefit from a second public comment period and first public hearing to either the environment or persons regulated or otherwise affected by the proposed rule, IDEM may forgo these comment periods and proceed directly to the public hearing and board meeting at which the draft rule is considered for adoption. Two opportunities for public comment (with this notice and at the public hearing prior to adoption ofthe rule) remain under this procedure. If the commissioner makes the determination of no anticipated benefit required by IC 13-14-9-8, the commissioner shall prepare written findings and publish those findings in the Indiana Register prior to the board meeting at which the draft rule is to be considered for adoption and include them in the board packet prepared for that meeting. This document constitutes the commissioner's written findings pursuant to IC 13-14-9-8. The statute provides for this shortened rulemaking process ifthe commissioner determines that: (1) the rule constitutes:

(A) an adoption or incorporation by reference of a federal law, regulation, or rule that: (i) is orwill be applicable to Indiana; and (ii) contains no amendments that have a substantive effect on the scope or intended application ofthe federal law or rule; (B) a technical amendment with no substantive effect on an existing Indiana rule; or (C) an amendment to an existing Indiana rule, the primary and intended purpose ofwhich is to clarify the existing ruie; and (2) the rule is ofsuch nature and scope that there is no reasonably anticipated benefit to the environment or the persons referred to in IC 13-14-9-7(a)(2) from: (A) exposing the rule to diverse public comment under IC 13-14-9-3 or IC 13-14-9-4; (B) affording interested or affected parties the opportunity to be heard under IC 13-14-9-3 or IC 13-14-9-4; and (C) affording interested or affected parties the opportunity to develop evidence in the record collected under IC 13-14-9-3 and IC 13-14-9-4. BACKGROUND Warrick Power Plant, located in Newburgh, Indiana, is a generating facility located along the Ohio Riverjust east of Evansville that provides power to Alcoa Warrick Operations, and is one ofAlcoa's largest manufacturing facilities. The power plant includes four boilers feeding steam-powered turbines generating a combined capacity of 791 megawatts. Currently, 326 lAC 26-2-2(2)(C)(i) limits the emissions of nitrogen oxides (NO ) by APGI to 0.38 pound per million British thermal units (lb/MMBtu) for boilers two and three. Th·e NO emissiofl limit, along with the other limits in 326 lAC 26-2, was established as best available retrofit technology (BART). On April 30, 2013, APGI- Warrick Power Plant requested that IDEM initiate a state implementation plan (SIP) revision that would make a technical correction to 326 lAC 26-2-2(2)(C)(i). The current particulate matter (PM), sulfur dioxide (S02), and NO emission limitations for Unit 1 specified in 326 lAC 26-2-2(1) are in the form of a 24-hour daily average basis; h8wever, the NO emission limit for units two and three, as indicated in 326 lAC 26-2-2(2)(C)(i) is on a 24-hour rolling average

### basi~. Date: Jul14,2014 2:23:22PM EDT DIN: 20131120-IR-326130503FDA Page 1Indiana Register The BART analysis provides for an NO emission limit independent ofthe averaging period. The 24-hour rolling· average is an error carried over from'the BART analysis to the rule language, and increases the opportunity for exceedances of the standard compared to a 24-hour daily average since a new average is calculated every hour. APGI has stated that compliance with the NO emission limit on a 24-hour rolling average would present an "undue hardship or burden" and was granted a valiance from the requirement at 326 lAC 26-2-2(2)(C)(i) in accordance with IC 13-14-8-8. All other BART emission limits at 326 lAC 26-2-2 are in the form ofa 24-hour daily average, and the 24-hour rolling average currently in this section ofthe rule is incorrect. In this rulemaking, IDEM is proposing to correct the language in 326 lAC 26-2-2(2)(C)(i) as well as proposing administrative corrections. IC 13-14-9-4 Identification of Restrictions and Requirements Not Imposed under Federal Law No element ofthe draft rule imposes either a restriction or a requirement on persons to whom the draft rule applies that is not imposed under federal law. This draft rule imposes no restrictions or requirements because it is a technical amendment with no substantive effect on an existing Indiana rule. Potential Fiscal Impact Because this is a technical amendment with no substantive effect on existing Indiana rule, no impact beyond that already imposed by current Indiana rule is imposed by this rulemaking. Therefore, there will be no fiscal impact from the implementation ofthis rulemaking. Public Participation and Work Group Information At this time, no work group is planned for the rulemaking. Ifyou feel that a work group or other informal discussion on the rule is appropriate, please contact Zachary Ruzycki, Rules Development Branch, Office of Legal Counsel at (317) 232-8229 or (800) 451-6027 (in Indiana). Small Business Assistance Information IDEM established a compliance and technical assistance program (CTAP) under IC 13-28-3. The program provides assistance to small businesses and information regarding compliance with environmental regulations. In accordance with IC 13-28-3 and IC 13-28-5, there is a small business assistance program ombudsman to provide a point of contact for small businesses affected by environmental regulations. Information on the CTAP program, the monthly CT AP newsletter, and other resources available can be found at: www.in.gov/idem/ctap For purposes of IC 4-22-2-28.1, small businesses affected by this rulemaking may conta.ct the Small Business Regulatory Coordinator: Jessica Faust-Hamblin IDEM Small Business Regulatory Coordinator MC 60-04 IGCS W041 402 West Washington Street Indianapolis, IN 46204-2251

## Okay. The next is a public hearing before 9 the**Environm~ntai** 

## Rules Board concerning final 10 adoption of amendments to rules in 11 326 

## IAC 26-2-2 1 

## the Alcoa Best Available Retrofit 12 Technology/ BART 1 

## Revisions.- I will now 13 introduce Exhibit D 1 

## the draft rules 1 

## into the 14 record of the hearing. 15 chris? 16 

## MS. PEDERSEN: This rule makes a 17 correction to rule language for Warrick Power 18 Station for Alcoa Power Generating 1**Incorpor~ted** 

## 19 in the best available retrofit 1 

## or BARTr ·20 

## provisions in 326 

## IAC 26-2-2. 

## 21 The BART provisions are source specific 22 

## emission limits that are required by the Regional 23 

## Haze Rule that addresses**vis~bility** 

## in federal

### 1 

## class I areas. Federal class I areas are 2 basically national parks, wildlife areas, 3 national monuments, that type of thing. 34

4 Alcoa submitted an engineering analysis as 5 part of the original rulemaking that irtcluded 6 recommended limits for particu+ate matter, sulfur 7 

## dioxide and nitrogen oxides. For their Boilers 2 8 and 3, the averaging period for the NOx limit was 9 inadvertently submitted as a rolling average 10 instead of a daily average. All of the other 11 BART emission limits are in the form of a 24-hour 12 daily average, and the 24-hour rolling average 13 for NOx currently in this section of the rule is 14 incorrect. 15 On April 30th of 2013, Alcoa requested 16 that IDEM revise the rule to correct the mistake 17 

## in 326 IAC 26-2-2 (2) (C) (i). Alcoa has stated 18 that compliance with the NOx emission limit on a 19 24-hour rolling average would present an undue 20 hardship or burden, and was granted a variance 21 from the requirement in accordance with 22 IC 13-14-8-8. 23 This draft rule corrects existing rule

### 35



## 1 language by replacing "rolling" average with 2 ''daily" average, and makes a minor administrative 3 correction to an internal agency reference. 4 IDEM recommends adoption of this rule. 5 

## CHAIRMAN GARD: Are there any 6 

## questions or discussion for ChrisJ 7 Yes. 8 

## MS. ALEXANDROVICH: Yeah, I do have a 9**que~tion.** 

## Has this rule, as it stands today, 10 already been approved by EPA? Has it been 11 approved, or is that kind of pending on that list 12 of

-- 13 

## MS. PEDERSEN: No, this one's already 14 been approved. 15 16 

### 17 18 19 

## 20 21 22 23 

## MS. ALEXANDROVICH: other question is: Did IDEM the nature of the hardship? Okay. And my did Alcoa mention

MS. PEDERSEN: I believe it

-- I don't know the details, but with the 24 daily average, they would be looking at one value per day, whereas with the 24-hour rolling average, they're looking at one value each hour, so it's much more burdensome as far as how often they

have to look at it 1 

## and since it was deemed unnecessary and incorrect, they just wanted to have that changed so they were in compliance. CHAIRMAN**~ARD:** 

## Any further questions? Yes, Mr.· Rulon. MR: 

## RULON:. I'm just**wondering~** 

## in a situation like this where basically an Alcoa mistake was translated into the rule, does.Alcoa pay a fee or a penalty or some compensation for you guys fixing a rule that:they helped you write 1 

## or not? Just curious. MS. PEDERSEN: Not· that I'm aware. COMM. EASTERLY: No, but they do pay permit fees. Alcoa is a major source, so they would pay 1 

## I think 1 . 

## $187,500 a**yea~**
