Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of adequacy.

SUMMARY:

In this notice, EPA is notifying the public that EPA has found that the motor vehicle emissions budgets in the Lake and Porter Counties, Indiana (Northwest Indiana) ozone attainment demonstration and post 1999 Rate of Progress (ROP) plan are adequate for conformity purposes. These documents contain motor vehicle emission budgets for VOC for 2002, 2005, and 2007 and for NOX for 2007. On March 2, 1999, the D.C. Circuit Court ruled that submitted State Implementation Plans (SIPs) cannot be used for conformity determinations until EPA has affirmatively found them adequate. As a result of our finding, Northwest Indiana can use the motor vehicle emissions budgets from the submitted ozone attainment demonstration and the submitted post 1999 ROP plan for future conformity determinations. These budgets are effective June 13, 2001.

Background

Throughout this document, whenever “we,” “us” or “our” is used, we mean EPA. Today's notice is simply an announcement of a finding that we have already made. EPA Region 5 sent a letter to the Indiana Department of Environmental Management on May 9, 2001, stating that the motor vehicle emissions budgets in the Northwest Indiana submitted ozone attainment demonstration and ROP plan for 2002, Start Printed Page 291272005 and 2007 are adequate. This finding will also be announced on EPA's conformity website: http://www.epa.gov/​otaq/​transp/​, (once there, click on the “Conformity” button, then look for “Adequacy Review of SIP Submissions for Conformity”).

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. Transportation conformity to a 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). 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 EPA may later be disapprove the SIP.

We've described our process for determining the adequacy of submitted SIP budgets in guidance (May 14, 1999 memo titled “Conformity Guidance on Implementation of March 2, 1999 Conformity Court Decision”). We followed the guidance in making our adequacy determination.
