## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve elements of a state implementation plan (SIP) submittal from the State of California to meet Clean Air Act (CAA) Extreme area requirements for the 1997 8-hour ozone national ambient air quality standards (NAAQS) in the Riverside Co. (Coachella Valley), CA nonattainment area ("Coachella Valley"). We are specifically approving the reasonably available control measures (RACM) demonstration and attainment demonstration and finding the State has satisfied the clean fuels for boilers requirement. The EPA previously proposed to approve these elements in conjunction with a proposal to approve the vehicle miles traveled (VMT) offset demonstration and the reasonable further progress (RFP) demonstration for the Coachella Valley. The EPA intends to take final action on the area's VMT offset demonstration and RFP demonstration in a future rulemaking.
