Air Quality Study Report v Mount Vernon Avenue Bridge Project Table of Contents This page intentionally left blank. Air Quality Study Report vi Mount Vernon Avenue Bridge Project Executive Summary The San Bernardino County Transportation Authority (SBCTA), in cooperation with the California Department of Transportation (Caltrans), is proposing to replace the existing Mount Vernon Avenue Bridge (Bridge Number 54C-066) over the Burlington Northern Santa Fe (BNSF) rail yard in the City of San Bernardino, San Bernardino County, California. The project involves a road/railroad grade separation and is statutorily exempt from the California Environmental Quality Act (CEQA). A National Environmental Policy Act (NEPA) Finding of No Significant Impact (FONSI) was adopted for the project in June 2011. Since the NEPA document was adopted, it has been noted that additional
