Air Quality

We can’t see it. We can’t smell it. But air quality can have a significant impact on the transportation planning process. 

The Air Quality Conformity Determination Report documents compliance with the provisions of the Clean Air Act Amendments of 1990 (CAAA) and the Safe Accountable Efficient Transportation Equity Act: a Legacy for Users - 2005. The conformity determination for the current Transportation Improvement Program (TIP) is based primarily on a regional emissions analysis that utilized the transportation networks in the current adopted and conforming long-range Metropolitan Transportation Plans (MTPs) and the emissions factors developed by the North Carolina Division of Air Quality (NCDAQ).
