At the May 4, 2017 MPC meeting, the AQCD for the Federal Fiscal Year 2018-2021 Metropolitan Transportation Improvement Program (FY18-21 MTIP) and 2040 Regional Transportation Plan (RTP) will be presented for adoption.
An air quality conformity determination is required under Federal and State regulations whenever the Regional Transportation Plan or Metropolitan Transportation Improvement Program is updated for other than administrative amendments.
The Eugene and Springfield urban growth boundaries (UGBs) form an air quality maintenance area for coarse particulate matter (PM10). Under the State’s maintenance plan for this area, transportation projects within the two UGBs must be shown to not cause or contribute to local air quality violations. Project sponsors are required to address this verification at the time projects are designed just prior to construction (reviewing and potentially undertaking “hot spot” analyses). Within the draft MTIP, the “Air Quality Status” of each listed project indicates those projects that are likely to undergo review and possible analysis prior to release of funds by USDOT. This listing will be reviewed and possibly altered during the required interagency consultation with regulators prior to the MTIP adoption and approval.
Measurements show that the PM10 levels within the Eugene and Springfield UGBs remain below the National Ambient Air Quality Standards (NAAQS). With this demonstration and adequate response to the transportation conformity regulations, it is certain that the FY18-21 MTIP and 2040 RTP air quality conformity determination will be found to be in conformity.
