Final Rule Making Findings of Failure To Submit Required State Implementation Plan: Oregon

EPA is taking final action in making a finding, pursuant to sections 179(a)(1) and 110(k) of the Clean Air Act (CAA or Act), as amended in 1990 (Pub. L. No. 101-549, November 15, 1990), 42 U.S.C. 7509(a)(1) and 7410, for the state of Oregon. The EPA has determined that Oregon has failed to submit a state implementation plan (SIP) for particulate matter less than or equal to 10 microns (PM-10) as required under the provisions in the Act for the Medford-Ashland nonattainment area. This rule addresses the requirement under section 189(a)(2)(A) of the Act that each state shall submit the SIP required under section 189(a)(1) within one year of the date of the enactment of the Clean Air Act Amendments of 1990 (i.e., by November 15, 1991) for areas designated nonattainment for PM-10 under section 107(d)(4). Other provisions required under section 189(a)(1)(A) were due at a later date (i.e., provisions relating to new source review). This action triggers the 18-month time clock for mandatory application of sanctions in the Medford-Ashland PM-10 nonattainment area under the Act. This action is consistent with the CAA mechanism for assuring SIP submission.
