Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision; South Coast Air Quality Management District; Ventura County Air Pollution Control District; Mojave Desert Air Quality Management District

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern rules from the South Coast Air Quality Management District (SCAQMD), Ventura County Air Pollution Control District (VCAPCD), and Mojave Desert Air Quality Management District (MDAQMD). This approval action will incorporate two rules into the federally approved SIP and remove two rules from the SIP. The intended effect of approving these rules is to regulate emissions of volatile organic compounds (VOCs) in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). The two rules control VOC emissions from storage tank cleaning and degassing operations and from components at crude oil and natural gas production and processing facilities. The two rules to be removed control VOC emissions from pumps, compressors, and relief valves. Thus, EPA is finalizing the approval of these revisions of 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.
