Transportation plans, programs, and projects in maintenance areas must conform with Federal or State Implementation Plans for maintaining the national ambient air quality standards (NAAQS). Maintenance areas, as defined by the 1990 Clean Air Act Amendments, are geographic regions of the country that have achieved the national ambient air quality standards (NAAQS) for a given pollutant and must now maintain that achievement. State or Federal Implementation plans identify the strategies and programs maintenance areas will continue to provide for the continuation of their attainment status. In Ohio, the Ohio Environmental Protection Agency (OEPA) is the lead agency for coordinating development of the State Implementation Plan (SIP) and redesignation requests. The Ohio Department of Transportation, the area Metropolitan Planning Organizations (MPOs), and the Local Air Agencies participated in the development of the SIP, the redesignation requests and transportation plans and Transportation Improvement Programs (TIP)s. |
