Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision; San Joaquin Valley Unified Air Pollution Control District

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern a rule from the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). The revised rule controls emissions of volatile organic compounds (VOCs) from in-situ combustion well vents. This approval action will incorporate this rule into the Federally approved SIP. The intended effect of approving this rule is to regulate VOC emissions in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). In addition, the final action on this rule serves as a final determination that the finding of nonsubmittal for this rule has been corrected and that on the effective date of this action, any Federal Implementation Plan (FIP) clock is stopped. Thus, EPA is finalizing the approval of these revisions 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.
