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 11 0 of the Clean Air Act and Title 13 of the Indiana Code, the 

Indiana Department of Environmental Management (IDEM) submits an amendment to the 

Indiana state implementation plan. This amendment consists of revisions 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 conection to rule language for Wanick Power Station at Alcoa Power 

Generating Inc., located in Newburgh, Indiana, in the Best Available Retrofit Technology 

(BART) provisions in 326 lAC 26-2-2. Alcoa submitted an engineering analysis as part of the 

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 of a daily average. All other 

BART emission limits are in the fmm of a 24-hour daily average, and the 24-hour rolling 

average for NOx cunently in this section of the rule is incmTect. The BART analysis is 

independent of averaging. On April30, 201.3, Alcoa requested that IDEM revise the rule to 

correct the mistake in 326 lAC 26-2-2(2)(C)(i). · 

This submittal consists of one (1) hard copy of the required documentation. An 

electronic vei'sion of the 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 of this state 

implementation plan submission, a list of suppmiing documents is attached. 

Throughout the development of these amendments to the existing rule, staff of the Office 

of Air Quality worked closely with your staff to ensure that any potential problems that might 

exist with this requested state implementation plan revision would be resolved. I request that 

An Equal Opportunity Employer 0 @ Recycled Paper A State that~ 
U.S. EPA approve this modification of Indiana's state implementation plan. If you have any 

questions regarding this submittal, please contact Mike Dalton, Rule Support Section Chief,

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 of these 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 under the 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 of the 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 if the commissioner determines that: 

(1) the rule constitutes: 

(A) an adoption or incorporation by reference of a federal law, regulation, or rule that: 

(i) is or will 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 of which is to clarify the 

existing ruie; and 

(2) the rule is of such 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 River just 

east of Evansville that provides power to Alcoa Warrick Operations, and is one of Alcoa'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 1 
Indiana Register 

The BART analysis provides for an NO emission limit independent of the 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 of a 24-hour daily 

average, and the 24-hour rolling average currently in this section of the 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 of the 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 of this rulemaking. 

Public Participation and Work Group Information 

At this time, no work group is planned for the rulemaking. If you 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:

8 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 D1 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.

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~ in permit 

fees. 

MR. RULON:· So, there's some 

COMM. EASTERLY: So, it's not that 

they don't pay anything.
