SUPPLEMENTAL INFORMATION

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

Background

Today's action is simply an announcement of a finding that we have already made. EPA Region 5 sent a letter to the Wisconsin Department of Natural Resources on November 6, 2007, stating that the 2012 and 2018 MVEBs in Kewaunee County are adequate. Wisconsin submitted the budgets as part of the 8hour ozone redesignation request and maintenance plan for this area. This submittal was announced on EPA's conformity website, and received no comments: http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm , (once there, click on ``What SIP

submissions are currently under EPA adequacy review?'').

The 2012 and 2018 MVEBs, in tons per day (tpd), for volatile organic compounds (VOC) and oxides of nitrogen (NOX) for Kewaunee County are as follows:
2012 MVEB 2018 MVEB (tpd) (tpd) VOC........................................... 0.43 0.32 NOX........................................... 0.80 0.47

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 the criteria and procedures for determining whether or not they do. 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 motor vehicle emission budgets are adequate for 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 conformity Web site: http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm .
