ConnDOT: NOTICE OF AVAILABILITY-Air Quality Conformity Determination – PM 2.5





Air Quality Conformity Determination – PM 2.5



In July 1997, the U. S. Environmental Protection Agency (EPA) issued National Ambient Air Quality Standards (NAAQS) for fine particles designed to protect the public from exposure to PM 2.5 at levels that may cause health problems. Areas not meeting the PM 2.5 NAAQS are called PM 2.5 nonattainment areas. EPA designated The New York-Northern New Jersey-Long Island, NY-NJ-CT as a PM 2.5 nonattainment area. Connecticut portions include the Fairfield County and New Haven County areas.


These areas have had, or have contributed to, PM 2.5 levels higher than allowed under EPA's national air quality standards. Nonattainment areas are subject to a measure known as “transportation conformity,” which requires local transportation and air quality officials to coordinate planning efforts to ensure that transportation projects, such as road construction, do not affect an area's ability to reach its clean air goals.


By April 5, 2006, all PM 2.5 nonattainment areas must meet the transportation conformity requirements.   Failure to meet these requirements may result in withholding of federal funds for new transportation projects.


In accordance to this ruling, a PM2.5 Air Quality Conformity Determination of the 2004 Regional Transportation Plans and the FFY 2005-2009 Transportation Improvement Programs for the Connecticut portion of NY-NJ-CT PM2.5 Nonattainment area has been prepared.


The Air Quality Conformity Determination will be available for review for a thirty-day public comment period between February 1, 2006 and March 3, 2006 at the following Metropolitan Planning Organizations:
