Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Mojave Desert Air Quality Management District, San Luis Obispo County Air Pollution Control District

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern rules from the following districts: Mojave Desert Air Quality Management District (MDAQMD) and San Luis Obispo County Air Pollution Control District (SLOCAPCD). The rules control volatile organic compounds (VOC) emissions from components at pipeline transfer stations and petroleum- related industrial sources; oil-water separators; and petroleum pits, ponds, sumps, and well cellars. This approval action will incorporate these rules into the federally approved SIP. The intended effect of approving these rules is to regulate emissions of VOCs in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). In addition, the final action on MDAQMD Rules 464 and 1102 serves as a final determination that the findings of nonsubmittal for these rules have been corrected and that on the effective date of this action, any Federal Implementation Plan (FIP) clocks associated with such submittals are stopped. Thus, EPA is finalizing the approval of these rules into the California SIP under provisions of the CAA regarding EPA action on SIP submittals, SIPs for national primary and secondary ambient air quality standards and plan requirements for nonattainment areas.
