Final Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Ventura County Air Pollution District

EPA is finalizing limited approval and limited disapproval of revisions to the California State Implementation Plan (SIP) proposed in the Federal Register on March 9, 2000. This limited approval and limited disapproval action will incorporate Rules 10-15, 15.1, 16, 23- 24, 26, 26.1-26.10, 29 and 30 of Ventura County Air Pollution District (District) into the federally approved State Implementation Plan (SIP). The intended effect of finalizing this limited approval is to strengthen the federally approved SIP by incorporating these rules and by satisfying Federal requirements for an approvable nonattainment area new source review (NSR) SIP for the District. While strengthening the SIP, however, this SIP revision contains deficiencies which the District must address before EPA can grant full approval under section 110(k)(3). Thus, EPA is finalizing simultaneous limited approval and limited disapproval as a revision to the California SIP under provisions of the Act regarding EPA action on SIP submittals, and general rulemaking authority. In addition to the above action, we are removing District Rules 18, 21, and 25 from the SIP, and deleting the conditions identified by us in 1981 for the District's 1981 NSR rule.
