Air Quality Conformity

About

The transportation system affects air quality. It is important to consider air quality when planning transportation projects because motorized vehicles emit pollutants. Projects that remove motorized vehicles from the road can reduce harmful emissions while projects that add capacity to roadways will often increase harmful emissions.

Federal transportation conformity (“conformity”) requirements ensure that federal funding and approval go to those transportation activities that are consistent with air quality goals. Conformity requirements apply 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. Regulations governing transportation conformity are found in Title 40 of the Code of Federal Regulations (40 CFR Parts 51 and 93).

Geographic areas that do not meet the federal air quality standards are designated as “nonattainment areas”. Geographic areas that at one time violated air quality standards, but no longer do, are designated as “maintenance areas”. FAMPO is designated as a maintenance area. Nonattainment and maintenance areas have special transportation planning requirements to help them conform to air quality standards. For example, new transportation plans must undergo an air quality conformity analysis.

Air Quality Conformity Analysis Report for FAMPO

The report linked below presents the air quality conformity assessment for FAMPO’s 2045 Long Range Transportation Plan (LRTP) and Fiscal Years 2021-2024 Transportation Improvement Program (TIP). The report indicates that the FAMPO 2045 LRTP and Fiscal Years 2021-2024 TIP demonstrate conformity with the Environmental Protection Agency’s transportation conformity rule and related guidance.
