Proposed Amendment to the CMPO Regional Transportation Plan (RTP) 2040

The Cache Metropolitan Planning Organization (CMPO) is seeking public review and comment on a proposed amendment to its Regional Transportation Plan (RTP). The RTP serves as the template for transportation development for highways, bicycle and pedestrian improvements and public transit in the Logan Urbanized region through the year 2040.

The amendment removes project II-5 that would realign and improve SR 30 from approximately 1200 West to Main Street in Logan Utah.

The CMPO is required to establish that all regionally significant highway and transit projects in air quality non-attainment areas are derived from a “conforming” Regional Transportation Plan (RTP).  A conforming Plan or Program is one that has been analyzed for emissions of controlled air pollutants and found to be within emission limits established in the State Implementation Plan (SIP) or approved Motor Vehicle Emission Budget. A conformity analysis has been prepared by the CMPO for this RTP amendment where the amended plan was found to conform to the approved motor vehicle emission budget and will be submitted to the Federal Highway Administration and the Federal Transit Administration for their concurrence.

Based on the analysis the amended CMPO 2040 RTP conforms to mobile source budget in the PM 2.5 Moderate Area State Implementation Plan for the Logan, UT-ID Nonattainment area. This mobile source budget was given an “adequacy determination” by EPA with an effective date of September 28, 2015.

Comments will be received for the proposed RTP amendment and Draft Air Quality Conformity Memorandum (2040RTP-2) until July 18, 2017.
