Project-Level PM2.5 Conformity Analysis
The project is in the San Francisco Bay Area, which is in nonattainment for the Federal standard for particulate matter less than or equal to 2.5 microns in diameter (PM2.5). The U.S. Environmental Protection Agency (EPA) requires certain projects in nonattainment areas to engage in interagency consultation and complete PM2.5 analyses as part of the project-level conformity determination process.
In the San Francisco Bay Area, interagency consultation is conducted through the Metropolitan Transportation Commission’s (MTC’s) Air Quality Conformity Task Force. The consultation process begins when a project sponsor submits a Project Assessment Form for PM2.5 Interagency Consultation to the MTC. The Air Quality Conformity Task Force reviews each form and determines whether each project is of air quality concern, as defined in 40 CFR 93.123(b)(1). Projects of air quality concern require a PM2.5 hot-spot analysis.
Alameda CTC submitted a Project Assessment Form for PM2.5 Interagency Consultation to MTC in October 2013 and met with the Air Quality Conformity Task Force on October 24, 2013. Click here to review the Project Assessment Form. On October 31, 2013, the Air Quality Conformity Task Force informed Alameda CTC that the project does not fit the description of a project of air quality concern regarding PM2.5 as defined in 40 CFR 93.123(b)(1).
Comment is requested regarding the project-level PM2.5 conformity analysis presented in the Project Assessment Form. Project-level conformity analysis was previously performed and approved for other pollutants for which the project area is designated nonattainment or maintenance, and is not the subject of this request for comment.
