SUPPLEMENTARY INFORMATION:

I. What Action Is EPA Taking Today?

EPA is notifying the public that delegation of the authority to implement and enforce the MACT standards for polyurethane foam, portland cement, hazardous waste combustion, oil and natural gas production, natural gas transmission and storage, publically owned treatment works, pulp and paper—non-combustion, phosphoric acid manufacturing, phosphate fertilizer production, tanks—level 1, containers, surface impoundments, individual drain systems, closed vent systems, equipment leaks—level 1, equipment leaks—level 2, oil-water separators, storage vessels—level 2, generic MACT, pesticide active ingredient production, mineral wool production, and wool fiberglass manufacturing was approved in a letter from EPA to IDEM dated December 29, 2003.

All notifications, reports and other correspondence required under section 112 standards should be sent to the State of Indiana rather than to the EPA, Region 5, in Chicago. Affected sources should send this information to: Indiana Department of Environmental Management, Office of Air Management, 100 North Senate Avenue, P.O. Box 6015, Indianapolis, Indiana 46206-6015.

II. EPA Approved the Delegation Under What Authority?

Section 112(l) of the CAA enables the EPA to approve State air toxics programs or rules to operate in place of the Federal air toxics program. The Federal air toxics program implements the requirements found in section 112 of the CAA pertaining to the regulation of hazardous air pollutants. Approval of an air toxics program is granted by the EPA if the Agency finds that the State program: (1) Is “no less stringent” than the corresponding Federal program or rule, (2) the State has adequate authority and resources to implement the program, (3) the schedule for implementation and compliance is sufficiently expeditious, and (4) the program is otherwise in compliance with Federal guidance. Once approval is granted, the air toxics program can be implemented and enforced by State or local agencies, as well as EPA.

On November 14, 1995, EPA approved Indiana's program of delegation for part 70 sources (Federal Register (60 FR 57118)). On July 8, 1997, EPA approved Indiana's program of delegation for non-part 70 sources (Federal Register (62 FR 36460)).

III. Which Standards Has IDEM Submitted to EPA for Approval Under Indiana's Air Toxics Program Delegation Mechanism?

On June 30, 2003, IDEM requested delegation of implementation and enforcement authority of the MACT standards for polyurethane foam, portland cement, hazardous waste combustion, oil and natural gas production, natural gas transmission and storage, publically owned treatment works, pulp and paper—non-combustion, phosphoric acid manufacturing, phosphate fertilizer production, tanks—level 1, containers, surface impoundments, individual drain systems, closed vent systems, equipment leaks—level 1, equipment leaks—level 2, oil-water separators, storage vessels—level 2, generic MACT, pesticide active ingredient production, mineral wool production, and wool fiberglass manufacturing (i.e., 40 CFR part 63, subpart III, LLL, EEE, HH, HHH, VVV, S, AA, BB, OO, PP, QQ, RR, SS, TT, UU, VV, WW, YY, MMM, DDD, and NNN respectively).
