Adequacy Status of the Milwaukee-Racine, Door County, Manitowoc 
County, and Sheboygan County, Wisconsin Areas Submitted 8-Hour Ozone 
Redesignation and Maintenance Plans for Transportation Conformity 
Purposes

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of adequacy.

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

SUMMARY: In this notice, EPA is notifying the public that we have found 
that the motor vehicle emissions budgets (MVEBs) for volatile organic 
compounds (VOCs) and oxides of nitrogen (NOx) in the 
Milwaukee-Racine area, Door County, Manitowoc County, and Sheboygan 
County, Wisconsin ozone nonattainment areas are adequate for use in 
transportation conformity determinations. Wisconsin submitted a 
redesignation request and maintenance plan for the Milwaukee-Racine 
area, Door County, Manitowoc County, and Sheboygan County, Wisconsin on 
September 11, 2009. As a result of our finding, these Wisconsin areas 
must use the MVEBs from the submitted ozone maintenance plan for future 
transportation conformity determinations.

DATES: This finding is effective May 21, 2010.

Engineer, Criteria Pollutant Section (AR-18J), Air Programs Branch, Air

SUPPLEMENTARY INFORMATION: Throughout this document, whenever ``we'', 
``us'' or ``our'' is used, we mean EPA.

Background

    Today's notice is simply an announcement of a finding that we have 
already made. On April 7, 2010, EPA Region 5 sent a letter to the 
Wisconsin Department of Natural Resources stating that the 2012 and 
2020 MVEBs for the Milwaukee-Racine area, Door County, Manitowoc 
County, and Sheboygan County, Wisconsin 8-hour ozone areas are 
adequate. Receipt of these MVEBs was announced on EPA's transportation 
conformity Web site, and no comments were submitted. The finding is 
available at EPA's conformity Web site: http://www.epa.gov/otaq/
stateresources/transconf/adequacy.htm.
    The adequate 2012 and 2020 MVEBs, in tons per day (tpd), for VOCs 
and NOx for the Wisconsin areas are as follows:

     Transportation conformity is required by section 176(c) of the 
Clean Air Act. EPA's conformity rule requires that transportation 
plans, programs, and projects conform to state air quality 
implementation plans and establishes

[[Page 24945]]

the criteria and procedures for determining whether or not they do 
conform. Conformity to a State Implementation Plan (SIP) means that 
transportation activities will not produce new air quality violations, 
worsen existing violations, or delay timely attainment of the national 
ambient air quality standards.
    The criteria by which we determine whether a SIP's MVEBs are 
adequate for transportation conformity purposes are outlined in 40 CFR 
93.118(e)(4). We have described our process for determining the 
adequacy of submitted SIP budgets in our July 1, 2004, preamble 
starting at 69 FR 40038, and we used the information in these resources 
while making our adequacy determination. Please note that an adequacy 
review is separate from EPA's completeness review, and it also should 
not be used to prejudge EPA's ultimate approval of the SIP. Even if we 
find a budget adequate, the SIP could later be disapproved.
    The finding and the response to comments are available at EPA's 
transportation conformity Web site: http://www.epa.gov/otaq/
stateresources/transconf/adequacy.htm.
