ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[MI73-7281b; FRL-6366-4]


Approval and Promulgation of State Implementation Plans; Michigan

AGENCY: Environmental Protection Agency.

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve the State's request to redesignate the Detroit area, which 
includes portions of Wayne, Oakland, and Macomb Counties, to attainment 
for carbon monoxide (CO). The EPA is also proposing to approve the 
corresponding 175A maintenance plan associated with the redesignation 
request as a revision to the Michigan State Implementation Plan (SIP) 
for attaining and maintaining the National Ambient Air Quality Standard 
for CO.
    In the final rules section of the Federal Register, EPA is 
approving the State's submittal as a direct final rule without prior 
proposal because EPA views this action as a noncontroversial action and 
anticipates no relevant adverse comments. A detailed rationale for the 
approval is set forth in the direct final rule. If no relevant adverse 
comments are received in response to this rule, no further activity is 
contemplated, and the direct final rule will become effective. If EPA 
receives relevant adverse comments, the direct final rule will be 
withdrawn, and all public comments received during the 30-day comment 
period set forth below will be addressed in a subsequent final rule 
based on this proposed rule. The EPA will not institute a second 
comment period on this action. Any parties interested in commenting on 
this action should do so at this time.

DATES: EPA must receive written comments by July 30, 1999.

ADDRESSES: Send written comments to: Carlton T. Nash, Chief, Regulation 
Development Section, Air Programs Branch (AR-18J), United States 
Environmental Protection Agency, 77 West Jackson Boulevard, Chicago, 
Illinois 60604.

FOR FURTHER INFORMATION CONTACT: John Mooney at (312) 886-6043.

SUPPLEMENTARY INFORMATION: For additional information see the direct 
final rule published in the rules section of this Federal Register. 
Copies of the documents relevant to this action are available for 
public inspection during normal business hours at the above address.
