ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[MI74-7282b; FRL-6896-4]

 
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 
adjust the applicability date for reinstating the 1-hour ozone National 
Ambient Air Quality Standard (NAAQS) in Genesee, Bay, Midland, and 
Saginaw Counties, Michigan and is proposing on a determination that 
these areas have attained the 1-hour ozone NAAQS. This determination is 
based on 3 consecutive years of complete, quality-assured, ambient air 
monitoring data for the 1997-1999 ozone seasons that demonstrate that 
the areas have attained the ozone NAAQS. On the basis of this 
determination, EPA is also proposing that certain attainment 
demonstration requirements, and certain related requirements of part D 
of subchapter I of the Clean Air Act (CAA), do not apply to Genesee, 
Bay, Midland, and Saginaw Counties.
    EPA is also proposing to approve the State of Michigan's request to 
redesignate Genesee, Bay, Midland, and Saginaw Counties to attainment 
for the 1-hour ozone NAAQS. Michigan submitted the redesignation 
request for these areas on May 9, 2000. EPA is also proposing to 
approve the State's plan for maintaining the 1-hour ozone standard for 
the next 10 years as a revision to the Michigan State Implementation 
Plan (SIP).
    In the final rules section of this Federal Register, EPA is 
approving the State's request as a direct final rule without prior 
proposal because EPA views this action as noncontroversial and 
anticipates no adverse comments. A detailed rationale for approving and 
disapproving portions of the State's request is set forth in the direct 
final rule. The direct final rule will become effective without further 
notice unless the Agency receives relevant adverse written comment on 
this proposed rule within 30 days of this publication. Should EPA 
receive adverse comment, it will publish a document informing the 
public that the direct final rule will not take effect and that EPA 
will address adverse comments in a subsequent final rule based on this 
proposed rule. If EPA does not receive adverse comments, the direct 
final rule will take effect on the date stated in that document and EPA 
will not take further action on this proposed rule. EPA does not plan 
to institute a second comment period on this action. Any parties 
interested in commenting on this document should do so at this time.

DATES: EPA must receive written comments by December 13, 2000.

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.
