Air Quality Conformity  

Air Quality Conformity

Transportation-related pollutants in the region are measured regularly to insure that new projects do not increase ozone depletion.

The Greater Bridgeport Planning Region is located in an area of Connecticut designated by the US Environmental Protection Agency (EPA) as non-attainment for two transportation-related pollutants – Eight Hour Ozone and Very Fine Particulate Matter.

Federal legislation requires that the plans, projects and programs developed by the region do not adversely impact air quality and include actions to reduce emissions. To demonstrate that the regional plans and program conform to this requirement, an air quality emissions analysis is performed that estimates the amount of pollution that would be generated from the transportation system. The total amount is then compared to the allowable emissions, referred to as “budgets,” as approved by EPA.


Air Quality Public Outreach 2016

October 6, 2016 - November 7, 2016

The Greater Bridgeport and Valley Metropolitan Planning Organization (GBVMPO) is opening the public involvement process, for a 30 day period, to receive comments on the air quality conformity evaluation of the current 2015 Regional Transportation Plans for the Greater Bridgeport and Valley planning regions and the 2015-2018 Transportation Improvement Program, as amended, with respect to the eight-hour ozone standard for the Connecticut portion of the New York-Northern New Jersey-Long Island, NY-NJ-CT Ozone Nonattainment Area and the annual fine particulate matter (PM2.5) standard for the Connecticut portion of the New York-New Jersey-Connecticut, NY-NJ-CT PM2.5 Nonattainment Area.

Support documents are below in PDF format and include the September 2016 Ozone Air Quality Determination and the September 2016 PM2.5 Air Quality Conformity Determination. Comments may be submitted through Monday, November 7, 2016.

Air Quality Reports

The region’s plans, projects and programs conform to the air quality goals when the estimated emissions are less than the allowed “budgets.” The analysis is performed for a base year and several future years. The most recent air quality analyses indicate that the region’s plans, projects and program are in conformity with EPA air quality goals:
