Approval and Promulgation of Air Quality Implementation Plans; 
Michigan; PSD Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA proposes to convert a conditional approval of revisions to 
the Michigan State Implementation Plan (SIP) to a full approval under 
the Federal Clean Air Act (CAA). The revisions consist of requirements 
of the prevention of significant deterioration (PSD) construction 
permit program in Michigan. As required by the conditional approval, 
Michigan has submitted a SIP revision pertaining to the ``potential to 
emit'' and ``emission unit'' definitions and EPA has found the 
revisions acceptable.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the State's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no adverse comments are received in response to this rule, no 
further activity is contemplated. If EPA receives adverse comments, the 
direct final rule will be withdrawn and all public comments received 
will be addressed in a subsequent final rule based on this proposed 
rule. EPA will not institute a second comment period. Any parties 
interested in commenting on this action should do so at this time. 
Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment. For 
additional information, see the direct final rule which is located in 
the Rules section of this Federal Register.
