This action makes several changes to the current regulation requiring transportation plans, programs, and projects to conform to state air quality implementation plans. This action allows any transportation control measure from an approved state implementation plan (SIP) to proceed during a conformity lapse; aligns the date of conformity lapses with the date of application of Clean Air Act highway sanctions for any failure to submit or submission of an incomplete control strategy SIP; extends the grace period before which areas must determine conformity to a submitted control strategy implementation plan; establishes a grace period before which transportation plan and program conformity must be determined in newly designated nonattainment areas; and corrects the nitrogen oxides provisions of the transportation conformity rule consistent with the Clean Air Act and previous commitments made by EPA. A transportation conformity SIP revision consistent with these amendments must be submitted to EPA by 12 months from November 14, 1995.
