ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[MI75-7284b; FRL-6907-2]


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 Allegan County, Michigan and is 
proposing on a determination that this area has 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 area has 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 Allegan County.
    EPA is also proposing to approve the State of Michigan's request to 
redesignate Allegan County to attainment for the 1-hour ozone NAAQS. 
Michigan submitted the redesignation request for these areas on 
September 1 and October 13, 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 
this 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 Allegan 
County 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 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 26, 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.
