Office of Air Management

Dear Mr. Dubenetzky:

This letter is in response to your February 14, 2005, and September 19, 2005, letters to the Acting Regional Administrator concerning the Clean Air Act, Section 112(l) delegation for Indiana. Under Indiana’s approved program for receiving delegation of Part 63 Maximum Achievable Control Technology (MACT) standards through the Section 112(l) delegation process (See 62 FR 36460 (July 8, 1997)), you requested delegation of implementation and enforcement authority of additional MACT standards. Further, you also requested delegation of Category I authorities under the general provisions for previously delegated MACT standards and for those standards being delegated by this letter.

You have requested the “straight” delegation of the MACT standards listed in Enclosure 1. We find that the following State of Indiana rules have incorporated the corresponding federal MACT standards unchanged from the federal standards: 326 Indiana Administrative Code (IAC) 20-49, 326 IAC 20-50, 326 IAC 20-51, 326 IAC 20-52, 326 IAC 20-53, 326 IAC 20-54, 326 IAC 20-55, 326 IAC 20-57, 326 IAC 20-58, 326 IAC 20-59, 326 IAC 20-60, 326 IAC 20-61, 326 IAC 20-62, 326 IAC 20-63, 326 IAC 20-64, 326 IAC 20-65, 326 IAC 20-66, 326 IAC 20-67, 326 IAC 20-68, 326 IAC 20-69, 326 IAC 20-70, 326 IAC 20-71, 326 IAC 20-72, 326 IAC 20-73, 326 IAC 20-74, 326 IAC 20-75, 326 IAC 20-76, 326 IAC 20-77, 326 IAC 20-78, 326 IAC 20-79, 326 IAC 20-82, 326 IAC 20-83, 326 IAC 20-84, 326 IAC 20-85, 326 IAC 20-86, 326 IAC 20-87, 326 IAC 20-88, 326 IAC 20-90, 326 IAC 20-91, 326 IAC 20-92, 326 IAC 20-93, and 326 IAC 20-94. Based on the above, the United States Environmental Protection Agency (U.S. EPA) hereby delegates to Indiana the implementation and enforcement authority for the 40 C.F.R. Part 63, Subparts: MM, UUU, CCCC, HHHH, TTTT, UUUU, XXXX, GGG, OOO, PPP, GGGG, BBBBB, SSSSS, NNNN, SSSS, JJJJ, MMMMM, AAAA, QQQQQ, J, RRR, LLLLL, JJJJJ, KKKKK, CCCCC, PPPPP, NNNNN, OOOO, RRRR, QQQQ, ZZZZ, EEEE, FFFF, IIII, KKKK, GGGGG, HHHHH, YYYY, AAAAA, EEEEE, FFFFF, and IIIII.

Further, U.S. EPA hereby delegates the applicable Category I authorities under the general provisions as set forth in 40 C.F.R. 63.91(g) to Indiana for all preciously delegated MACT standards as well as those MACT standards being delegated pursuant to this letter. (See also, 65 FR 55810 (September 14, 2000) and 68 FR 37334 (June 23, 2003)). Please note in the event that Indiana modifies any MACT standard pursuant to the Category I authorities, 40 C.F.R. 63.91(g)(1)(ii) requires that Indiana report such modifications to Region 5 in a semi-annual report.

This letter amends the delegation of Section 112 standards for Part 70 and non-Part 70 sources already delegated to the State. The existing delegated standards are listed in Enclosure 2.

Pursuant to Section 112(l)(7) of the Clean Air Act, nothing in this delegation prohibits U.S. EPA from enforcing any applicable emission standard or requirement.

A notice announcing these delegations will be published in the Federal Register in the near future. If you have any questions or comments, please feel free to contact me or Sam Portanova, of my staff, at (312) 353-2212 and (312) 886-3189 respectively.

Sincerely yours,

/s/
