Metropolitan Planning Organizations (MPOs) and the NCDOT are required under federal law by 23 CFR 134 and 40 CFR Parts 51 and 93 to make a conformity determination on any newly adopted or amended fiscally-constrained LRTPs and TIPs. The purpose of this web site is to share the working files and associated reports to all citizens to document 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.
This conformity determination for the 2012–2018 Transportation Improvement Program (TIP) is being coordinated through the Piedmont Authority for Regional Transportation (PART) on behalf of the Triad MPOs and the NCDOT. The determination of Air Quality conformity is based primarily on a regional emissions analysis that utilized the transportation networks in adopted and conforming 2035 Long Range Transportation Plans (LRTPs) and the emissions factors developed by the North Carolina Department of Environment and Natural Resources (NCDENR).
You will find various documents to assist in your understanding of Transportation Conformity on this page. For any question related to a specific project that you have feel free to contact your local transportation professional from the Metropolitan Planning Organization of your jurisdiction.
