Air Quality Conformity
Transportation conformity (“conformity”) is a way to ensure that federal funding and approval goes to those transportation activities that are consistent with air quality goals.
Conformity applies to transportation plans, transportation improvement programs (TIPs), and projects funded or approved by the Federal Highway Administration (FHWA) or the Federal Transit Administration (FTA) in areas that do not meet, or previously have not met, air quality standards for ozone, carbon monoxide, particulate matter, or nitrogen dioxide.
These areas are known as “nonattainment areas” or “maintenance areas,” respectively. Regulations governing transportation conformity are found in Title 40 of the Code of Federal Regulations (40 CFR Parts 51 and 93).
