2008 Transportation Fact Book The Atlanta Regional Commission has varying levels of planning responsibilities for five geographic areas. Please refer to the map and the matrix below to learn what counties are included in each of these planning boundaries and how ARC addresses each area in the transportation planning and air quality conformity process. What is ARC’s Planning Boundary? Boundary Color Boundary Name Regional Development Center (RDC) Previous Ozone Non-Attainment Area (1 hour standard) Metropolitan Planning Organization (MPO) Ozone Non-Attainment Area (8 hour standard) Particulate Matter (PM 2.5) Non-Attainment Area Number of Counties Included 10 Counties 13 Counties All of 13 counties; parts of 5 counties 20 counties All of 20 counties; part of 2 counties Planning Responsibilities ARC as the State designated Area Planning & Development Commission (APDC), is assigned the responsibilities of an RDC, one of 15 in the State. Every county in the state must be a member of an RDC and pay membership dues. RDCs facilitate intergovernment coordination and provide comprehensive planning assistance and other services to constituent jurisdictions. Prior to April 2004, this boundary was also the Atlanta MPO boundary. The Clean Air Act requires that regional transportation plans help non-attainment areas achieve clean air standards. The ten counties within the RDC area, as well as three others, were designated as an 1 hour ozone non-attainment area. On 6/14/05, EPA determined that attainment had been reached; on 6/15/05, EPA officially withdrew the 1-hour regulations. The 2000 census identified an expansion of the Atlanta urbanized area that encompassed portions of 19 counties (red). MPOs develop transportation plans for the current and future urbanized areas. ARC serves as the MPO for all or part of these 18 counties. A small portion of the Atlanta urbanized area falls within Hall County. By agreement, planning for that area is conducted by the Gainesville-Hall MPO. In April 2004, EPA implemented a new 8-hour standard for ozone. ARC has coordinated since that time with GHMPO’s planning efforts to demonstrate conformity for the entire non-attainment area. USDOT, in consultation with USEPA, made an initial conformity determination for this non-attainment area on 12/21/04, a second determination on 3/30/06, and a third on 10/10/07. EPA designated this non-attainment area in December 2004. In early 2006, ARC performed a technical analysis for the 20+ county non- attainment area which demonstrates conformity to PM 2.5 requirements. USDOT, in consultation with USEPA, made an initial conformity determination for this non-attainment area on 3/30/06, and a second determination on 10/10/07.
