Conformity

Last modified Tuesday, July 08, 2008 15:45

Mobile (transportation-related) emissions, as estimated by the ARC, must conform to established limits or Motor Vehicle Emissions Budgets (MVEB) for nonattainment pollutants and/or their precursors. MVEB are set by the State Air Agency, the Georgia Environmental Protection Division (EPD), in the SIP and are approved by the US EPA as adequate for use in the transportation conformity process.  For more information on transportation conformity, visit FHWA.

A positive conformity determination must be made for transportation plans and programs within air quality nonattainment areas in order for federal transportation funding to be allocated, without restriction, to the region.  This determination is provided by the US DOT with concurrence provided by US EPA.

The most recent conformity determination was provided as part of the Envision6 Regional Transportation Plan (RTP) and FY 2008-2013 Transportation Improvement Program (TIP).  A positive conformity determination was provided for both the ozone and particulate matter standards on October 10, 2007.  For more information on the conformity analysis reference Volume III (PDF) of Envision6 Plan Documentation.
