ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[MI42-7823; FRL-6851-4]


Approval and Promulgation of State Implementation Plans; Michigan

AGENCY: Environmental Protection Agency.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: The United States Environmental Protection Agency (EPA) is 
proposing to adjust the applicability date for the reinstating the 1-
hour ozone National Ambient Air Quality Standard (NAAQS) in Muskegon 
County, Michigan and is proposing to determine that the area has 
attained the 1-hour ozone NAAQS. This proposal is based on 3 
consecutive years of complete,

[[Page 52691]]

quality-assured, ambient air monitoring data for the 1997-1999 ozone 
seasons that demonstrate that the ozone NAAQS has been attained in the 
area. 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 the Muskegon area.
    EPA is also proposing to approve the State of Michigan's request to 
redesignate Muskegon County to attainment for the 1-hour ozone NAAQS. 
Michigan submitted the redesignation request for the Muskegon area on 
March 9, 1995, and submitted two updates to the request on June 14 and 
July 5, 2000. As part of this proposal, 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 this proposal and corresponding direct final rule, EPA 
is also notifying the public that we believe the motor vehicle 
emissions budgets for volatile organic compounds (VOC) and oxides of 
nitrogen (NOX) in the Muskegon, MI submitted maintenance 
plan are adequate for conformity purposes and approvable as part of the 
maintenance plan.
    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 we 
receive adverse comment, we will publish a document informing the 
public that the direct final rule will not take effect and that we will 
address adverse comments in a subsequent final rule based on this 
proposed rule. If we do 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. We do 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 September 29, 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.
