Air Quality Conformity

You are here: Studies & Reports | Air Quality Conformity

The YMPO has the responsibility to ensure that the transportation plans and programs within the YMPO planning boundaries, generally the greater Yuma area, conform to the state and national air quality plans and standards. Specifically, the emissions generated from proposed projects in the YMPO’s five-year Transportation Improvement Program (TIP) for 2014-2018 and the twenty-three-year Regional Transportation Plan (RTP) for 2014-2037 must be consistent with and conform to National Ambient Air Quality Standards (NAAQS).

Air Quality Conformity Analysis

The YMPO is required to undertake an air quality conformity analysis for two specific reasons: (1) to ensure that transportation investments (projects), strategies and programs, taken as a whole, have air quality impacts consistent with and conforming to state and national air quality plans and standards; and (2) to ensure that neither the transportation system as a whole nor individual transportation projects cause new air quality violations or worsen existing conditions.

Interagency Consultation Meetings

Interagency Consultation Meeting on Air Quality coordinate and reviews air quality conformity issues and analyses. Emissions analyses are used to demonstrate that federally funded and/or regionally significant transportation plans and projects will not cause or contribute to violations of federal air quality standards. FHWA, EPA, ADEQ, ADOT and the Yuma Metropolitan Planning Organizations (YMPO) collaborate on air quality conformity issues for Yuma County.Interagency Meeting Agenda – February 12, 2014
