Metropolitan Planning Organization Support

The Triangle region contains two Metropolitan Planning Organizations (MPOs) - the Capital Area MPO (NC CAMPO), which covers all of Wake County and portions of Granville, Franklin, Johnston, and Harnett counties, and the Durham-Chapel Hill-Carrboro MPO (DCHC MPO), which covers all of Durham County and portions of Orange and Chatham counties. These two MPOs are responsible for decision making about long-range transportation planning and transportation project funding within their respective areas. 

Focus of Work

Triangle J COG provides technical support to our region’s MPOs, particularly on regional issues that transcend MPO boundaries. The focus of our work is: 

Triangle Region Air Quality Conformity

The Triangle region is required by 40 CFR 51 and 93 to make a conformity determination on any newly adopted or amended fiscally constrained metropolitan transportation plan and TIP. In addition, the United States Department of Transportation (USDOT), specifically, the Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA), must make a conformity determination on MPO Plans in the Triangle region and the related TIPs in all non-attainment and maintenance areas.
