Approval of Section 112(l) Program of Delegation; Wisconsin

EPA is approving, through a ``direct final'' procedure, Wisconsin's request for delegation of the Federal air toxics program contained within 40 CFR Parts 61 and 63 pursuant to Section 112(l) of the Clean Air Act (CAA) as amended. The State's requested mechanism of delegation involves either the delegation of all existing and future Section 112 standards as federally promulgated, for promulgation as State standards (or rules), or to incorporate Federal standards into State air pollution control permits, reserving the right to promulgate the standards as a State rule at a later time. The actual delegation of authority will occur through a memorandum of agreement (MOA) between the Wisconsin Department of Natural Resources (WDNR) and EPA. This request for approval of the mechanism of delegation encompasses all sources not covered by the 40 CFR Part 70 operating permit program.
