Approval and Promulgation of Implementation Plans; State of California; Coachella Valley; Attainment Plan for 1997 8-Hour Ozone Standards

The Environmental Protection Agency (EPA) is approving state implementation plan (SIP) revisions submitted by the State of California to provide for attainment of the 1997 8-hour ozone national ambient air quality standards (NAAQS or "standards") in the Coachella Valley nonattainment area. The EPA finds the emissions inventories to be acceptable and is approving the reasonably available control measures, transportation control strategies and measures, rate of progress and reasonable further progress demonstrations, attainment demonstration, and vehicle miles traveled offset demonstration. We have determined that motor vehicle emissions budgets are not required for the 1997 8-hour ozone standards so we are not taking final action on this portion of the plan.
