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

The Environmental Protection Agency (EPA) is approving, through a ``direct final'' procedure, a request for a program 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 (Act) of 1990. The State's mechanism of delegation involves the straight delegation of all existing and future Section 112 standards unchanged from the Federal standards. The actual delegation of authority of individual standards, except for standards addressed specifically in this action, will be in the form of a letter from EPA to the Michigan Department of Environmental Quality (MDEQ). This request for approval of a mechanism of delegation encompasses all sources not covered by the Part 70 program. In the proposed rules section of this Federal Register, the EPA is proposing approval of, and soliciting comments on, this approval. If adverse comments are received on this action, the EPA will withdraw this final rule. It will then address the comments received in response to this action in a final rule based on the related proposed rule being published in the ``Proposed Rules'' section of this Federal Register. A second public comment period will not be held. Parties interested in commenting on this action should do so at this time. This approval makes the State's rule federally enforceable.
