Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Mojave Desert Air Quality Management District

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern negative declarations from the Mojave Desert Air Quality Management District (MDAQMD) for two source categories that emit volatile organic compounds (VOC): Asphalt Air Blowing and Vacuum Producing Devices or Systems. The MDAQMD has certified that these source categories are not present in the District and this information is being added to the federally approved State Implementation Plan. The intended effect of approving these negative declarations is to meet the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). In addition, the final action on these negative declarations serves as a final determination that the finding of nonsubmittal for these source categories 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.
