What is conformity?
Conformity is the process of assessing the compliance of any transportation plan, program or project with air quality implementation plans. It is a way to ensure that Federal funding and approval are given to those transportation plans that are consistent with air quality goals. According to the Clean Air Act of 1991, transportation plans cannot:
- Create new violations of the Federal air quality standards.
- Increase the frequency or severity of existing violation of the standards.
- Delay attainment of standards

Because driving is so closely linked to air pollution, federal law requires the High Point Urban Area's Long Range Transportation Plan to support the goals of North Carolina's air quality plans. Without this "conformity", the urban area risks losing its federal transportation funds.
