Staff representatives of both the Southern California Association of Governments and the South Coast Air Quality Management District were contacted to determine how the new AQMP applies to this project. Their response was that the AQMP addresses only transportation projects of state- wide or region -wide significance, such as freeway and highway projects, new transportation corridors, mass transit proposals, etc. Local roadway improvements, such as the proposed Bristol Street widening, are not specifically addressed in the AQMP. Conformity criteria for local highway projects, such as the Bristol Street widening project, have not yet been developed. On November 3, 1987, the Ninth Circuit Court of Appeals issued an opinion vacating and ordering disapproval of the Environmental Protection Agency's (EPA's) previous approval of ozone and carbon monoxide (CO) control measures for the South Coast Air Basin (SCAB). The State Implementation Plan (SIP) for ozone and CO in SCAB was disapproved by EPA on January 22, 1988. The project is in an area where there is not an approved SIP currently containing any enforceable Transportation Control Measures (TCM's) for ozone and CO. Therefore, the conformity procedures of 23 CFR 770 do not apply to this project. A SIP revision has been developed for this area by the local air quality and transportation planning agencies, but that SIP revision has not been approved by EPA (Summer 1990). A Federal Improvement Plan (FIP) for the project area was approved by the. EPA on July 30, 1990. Roadway widening projects that do not specifically address existing TCM's have not been included in the FIP. However, the mobile emission analysis of the area's air quality management plan included in the proposed SIP revision is based on a Regional Transportation Plan (and Program) that includes this project. Therefore, it is expected that the project would conform to the FIP and the SIP revision, when it is approved for the project area. Mitigation Measures Measures selected for incorporation in the project include: SCAQMD Rule 403 will be adhered to, insuring the clean-up of construction - related dirt on approach routes to the site. 2. Adequate watering techniques will be employed to partially mitigate the impact of construction- generated dust particulates. 3. Construction equipment will be properly maintained and serviced to minimi .e exhaust emissions. IV -19
