Air Quality Conformity

The State of Connecticut and each of the state's planning regions is required to demonstrate that transportation programs and long range transportation plans do not violate the federal Clean Air Act of 1990 (1990 CAAA). The Connecticut Department of Transportation (CTDOT) performs transportation and air quality modeling for the entire state. CTDOT's compliance assessment has determined that all elements of CTDOT's transportation program and the regional long range transportation plans conform to applicable State Implementation Plan and 1990 CAAA Conformity Guidance criteria as well as the revised transportation conformity budgets approved by U.S. EPA effective February 4, 2004. Links to the latest CTDOT Air Quality Conformity Report and the South Western Region MPO's Air Quality Conformity Statement are provided.

CTDOT Air Quality Conformity

The CTDOT has update the Air Quality Conformity reports  for Ozone and PM2.5 originally dated January 2011 to include the 2011 Regional Transportation Plans.

The emissions analysis demonstrated conformity for the Connecticut portion of the New York-New Jersey-Connecticut non-attainment area for both Ozone and PM_2.5. Results indicated that the projects and recommendations included in the plan will assist with improving air quality in the non-attainment area and move towards meeting all NAAQS.

The South Western Metropolitan Planning Organization (MPO) is opening the public involvement process for a two week period, to receive comments on the air quality conformity evaluation of our current 2011-2040 Long Range Transportation Plan and current 2012-2015 Transportation Improvement Program with respect to the new 2008 eight-hour ozone standard. The two week period is effective from June 13 through June 26, 2013.
