(52) On February 23, 1984, the Indiana Air Pollution Control Board submitted a revision to Indiana's SO₂ SIP waiving the self-monitoring requirement for Public Service Indiana's Edwardsport Generating Station, as set forth in section 4(a) of Rule 325 IAC 7-1. See (c)(19). This revision becomes effective once the Edwardsport Station achieves an annual operating capacity of no greater than 10%.

(53) On October 6, 1980, Indiana submitted revised opacity regulation 325 IAC 5-1. It replaces 1972 APC 3 for process sources, approved at paragraph (b), and SIP 1974 APC 3 for combustion sources, approved in part at subparagraph (c)(14). Indiana does not intend 325 IAC 5-1 to regulate the emission points in Lake County listed in Table 2 of 325 IAC 6-1-110.2 (subparagraph (c)(57)). USEPA is disapproving 325 IAC 5-1 for these sources. Indiana does not intend 325 IAC 5-1 to regulate certain coke battery emission sources listed in 325 IAC 11-3 (subparagraph (c)(42)). USEPA is disapproving 325 IAC 5-1 as it applies to the provisions of 325 IAC 11-3 which USEPA disapproved at (c)(42), i.e., pushing and quenching sources throughout the State and coke oven doors in Lake and Marion Counties. Additionally, Indiana has modified 325 IAC 5-1 as it applies to the stack emission points in Porter County listed at 325 IAC 6-6-4. USEPA disapproved 325 IAC 5-1 as it applies to these Porter County sources on February 5, 1987 (52 FR 3640). For those source categories where USEPA is disapproving 325 IAC 5-1, they remain regulated by the previously approved opacity SIP which consists of SIP 1974 APC 3 for combustion sources and 1972 APC 3 for process sources. Additionally, as long as the Bethlehem Steel Corporation No. 2 Coke Oven Battery Underfire Stack EVEL (subparagraph (c)(49)) remains approved, it replaces 325 IAC 5-1.

(i) Incorporation by reference. (A) On January 13, 1984, Indiana issued to Richmond State Hospital an amendment to operating permit, 89-04-85-0153, which revised its TSP emission limitations for the four boilers to 0.60 lbs/MMBTU with an annual total limit of 452 tons/yr.

(55) On January 30, 1985, Indiana submitted revised VOC regulations 325 IAC 8-1.1, 8-2, 8-3, 8-4 and 8-5 to satisfy certain conditions of USEPA's approval. Those regulations amended those approved at (c)(33) and (c)(34). In addition, the applicability of the regulations was extended to cover St. Joseph and Elkhart Counties. USEPA is taking no action on changes to 325 IAC 8-1.1-2(f), Methods of Compliance, and the repeal of 325 IAC 8-5-6, Perchloroethylene Dry Cleaning, because these exempt the compound perchloroethylene from control without the State justifying that such exemption is consistent with the Part D reasonably available control technology (RACT) requirements.

(i) Incorporation by reference. (A) Indiana's Volatile Organic Compounds (VOC) RACT I and II regulations, Title 325 Air Pollution Control Board:

(1) 325 IAC 8-1.1, Establishes Volatile Organic Compound Emission Limitations. State promulgated on June 21, 1984, and amended November 7, 1984.

(66) On October 21, 1987, the State of Indiana submitted 325 IAC 7-1-3.1, Reporting Requirements and Methods to Determine Compliance, as a revision to its SO₂ plan. At paragraph (c)(19) of this section, USEPA approved/conditionally approved Indiana's SO₂ plan, 325 IAC 7-1, for most areas of the State. However, the emission limits in this plan were set aside by the Court of Appeals for the Seventh Circuit because USEPA took no action on the State's 30-day averaging compliance method in 325 IAC 7-1-3.
