Clean Air Act Section 112 Major and Area Source Standards
EPA's final delegation approval of Section 112 NESHAP standards for Ohio constitutes a program of straight delegation of all existing and future air toxic standards regardless of a source's Part 70 (Title V) applicability with the exception of the Coke Oven standard (40 CFR part 63 subpart L).
In 1994, EPA gave approval to Ohio EPA for its Title V program. Under this approval, a mechanism was established by which Ohio EPA was granted authority to implement and enforce present and future Section 112 NESHAP standards. Ohio EPA will have the authority to implement each Section 112 standard as promulgated unless Ohio EPA notifies EPA differently.
Ohio EPA will enforce Section 112 NESHAP standards through the Title V permit, federally enforceable state operating permit and the new source review permit programs. Pursuant to Ohio Revised Code §3704.036(A), Ohio EPA has the authority to include Section 112 requirements in Title V permits. Therefore, delegation will be implemented on a source by source basis.
