§ 52.776 Control strategy: Particulate matter.
(a) The requirements of subpart G of this chapter are not met since the plan does not provide for attainment and maintenance of the secondary standards for particulate matter in the Metropolitan Indianapolis Intrastate Region.
(b) APC 4-R of Indiana's “Air Pollution Control Regulations” (emission limitation for particulate matter from fuel combustion sources), which is part of the control strategy for the secondary standards for particulate matter, is disapproved for the Metropolitan Indianapolis Intrastate Region since it does not provide the degree of control needed to attain and maintain the secondary standards for particulate matter. APC 4-R is approved for attainment and maintenance of the primary standards for particulate matter in the Metropolitan Indianapolis Intrastate Region.
(c) APC-3 of Indiana's Air Pollution Control Regulations (visible emission limitation) is disapproved insofar as the phrase “for more than a cumulative total of 15 minutes in a 24-hour period” will interfere with attainment and maintenance of particulate standards.
(d) [Reserved]
(e) Part D—Conditional Approval—The complete Indiana plan for Clark, Dearborn, Dubois, Marion (except for coke batteries), St. Joseph, Vanderburgh, and Vigo Counties is approved provided that the following condition is satisfied:
(1) The Part D Plan must contain Industrial Fugitive Dust Regulations. The State must submit these by July 31, 1982.
(f) 325 IAC 11-3-2(f), (as amended on August 27, 1981) is not approved as it applies to Lake and Marion Counties, insofar as it does not meet the requirements of section 172(b)(3) of the Clean Air Act.
(g) 325 IAC 11-3-2(g) and 11-3-2(h) (as amended on August 27, 1981) are disapproved insofar as they do not meet the requirements of section 110(a)(2)(D) of the Clean Air Act.
(h) Equivalent Visible Emission Limits (EVEL). (1) A 20% 2-hour opacity limit for the underfire stack at Bethlehem Steel Corporation's Coke Battery No. 2 in Porter County is approved as an EVEL to determine compliance with the 325 IAC 6-2 SIP limit of 0.33 lbs/MMBTU. This EVEL is approved for as long as the SIP mass emission limit for this source remains the same as determined by 325 IAC 6-2 (October 6, 1980, submittal). See § 52.770(c)(6), (35), and (42).
(2) Revised opacity limits for the boilers at Olin Corporation in Warren County are approved at § 52.770(c)(51) as an EVEL to determine compliance with the 325 IAC 6-2 SIP limit of 0.80 lbs/MMBTU. This EVEL is approved for as long as the SIP mass emission limit for this source remains the same as determined by 325 IAC 6-2 (October 6, 1980 submittal). See § 52.770(c)(6) and (35).
(i) 325 IAC 6-2.1 is approved with the State's March 27, 1985, commitment that any “bubble” approved by the State under 325 IAC 6-2.1-2(b) and 3(b) will also be subject to the State's general “bubble” regulation, 325 IAC 2-4. The State additionally committed that until such time as 325 IAC 2-4 is approved as a part of the SIP, all such limits approved under the bubbling provisions of 325 IAC 6-2.1-2(b) and 3(b) will be submitted as site specific revisions to the SIP. Unless and until these emission point specific limits are approved as a portion of the SIP, the SIP limit for each individual emission point will remain the general limit calculated by means of the formulae in 325 IAC 6-2.1-2(a) and 3(a), even though a revised emission point specific limit has been adopted by Indiana under 325 IAC 6-2.1-2(b) and 3(b). See 52.770(c)(50).
