40 CFR Part 52

[WI116-01-7346b; FRL-7515-6]


Approval and Promulgation of Implementation Plans; Wisconsin; 
Revised Motor Vehicle Emissions Inventories and Motor Vehicle Emissions 
Budgets Using MOBILE6

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing approval of a revision to the Wisconsin State 
Implementation Plan (SIP) for the attainment and maintenance of the 
one-hour national ambient air quality standard (NAAQS) for ozone. 
Specifically, EPA is approving Wisconsin's revised 2007 motor vehicle 
emission inventories and 2007 Motor Vehicle Emissions Budgets (MVEB) 
recalculated using MOBILE6 for the Milwaukee severe ozone area and the 
Sheboygan ozone maintenance area. EPA is also proposing approval of a 
new

2012 projected MVEB for the Sheboygan ozone maintenance area.
    In the ``Rules and Regulations'' 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. The rationale for approval is set 
forth in the direct final rule. If EPA receives no written adverse 
comments, EPA will take no further action on this proposed rule. If EPA 
receives written adverse comment, we will publish a timely withdrawal 
of the direct final rule in the Federal Register and inform the public 
that the rule will not take effect. In that event, EPA will address all 
relevant public comments in a subsequent final rule based on this 
proposed rule. In either event, EPA will not institute a second comment 
period on this action. Any parties interested in commenting must do so 
at this time.

DATES: Comments on this action must be received by July 21, 2003.

ADDRESSES: Written comments should be mailed to: Carlton Nash, Chief, 
Regulation Development Section, Air Programs Branch (AR-18J), USEPA, 
Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604.
    A copy of the plan revision request is available for inspection at 
the Environmental Protection Agency, Region 5, Air and Radiation 
Division, 77 West Jackson Boulevard, Chicago, Illinois 60604. (Please 
telephone Michael Leslie at (312) 353-6680 before visiting the Region 5 
Office.)
