Public Notice on a Proposed Amendment to the FY 2022-2025 MAG Transportation Improvement Program, Momentum 2050 MAG Regional Transportation Plan, and Conformity Analysis

The Maricopa Association of Governments is notifying the public of a proposed amendment to the FY 2022-2025 MAG Transportation Improvement Program (TIP) and MOMENTUM 2050 MAG Regional Transportation Plan (RTP). The proposed amendment requires a new conformity determination. A conformity analysis has been conducted for the proposed amendment to the TIP and RTP. Both the proposed amendment and conformity analysis are being provided for review and comment through the MAG Conformity Consultation Process with comments requested by 5:00 p.m. on December 29, 2022.

The proposed amendment to the FY 2022-2025 TIP and MOMENTUM 2050 MAG RTP includes changes to highway projects and transit projects. The conformity analysis includes a regional emissions analysis to support a finding that the amendment to the TIP and RTP meet transportation conformity requirements for carbon monoxide, eight-hour ozone, and particulate matter PM-10 in the Maricopa nonattainment and maintenance areas, and PM-10 and PM-2.5 in the Pinal County nonattainment areas. The results of the conformity analysis indicate that the proposed amendment, when considered together with the TIP and RTP as a whole, will not contribute to violations of federal air quality standards.
