Final Rule Making a Finding of Failure to Submit a Required State Implementation Plan for Particulate Matter, CaliforniaOwens Valley

EPA is taking final action in making a finding, under the Clean Air Act (CAA or Act), that California failed to make a particulate matter (PM-10) nonattainment area state implementation plan (SIP) submittal required for the Owens Valley Planning Area under the Act. Under certain provisions of the Act, states are required to submit SIPs providing for, among other things, reasonable further progress and attainment of the PM-10 national ambient air quality standards (NAAQS) in areas classified as serious. The deadline for submittal of this plan for the Owens Valley Planning Area was February 8, 1997. This action triggers the 18-month time clock for mandatory application of sanctions and 2-year time clock for a federal implementation plan (FIP) under the Act. This action is consistent with the CAA mechanism for assuring SIP submissions.
