Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision; Kern County Air Pollution Control District, Sacramento Metropolitan Air Quality Management District

EPA is taking direct final action to approve revisions to the California State Implementation Plan (SIP). The revisions concern rules from the following districts: the Kern County Air Pollution Control District (KCAPCD) and the Sacramento Metropolitan Air Management Control District (SMAQMD). This approval action will incorporate two rules into the federally approved SIP and remove one rule from the SIP. The two rules control oxides of nitrogen (NO<INF>x) emissions from the operations of stationary gas turbines and the rule to be removed controls NO<INF>x emissions from steam generators used in the oil production operations. The intended effect of approving these rules is to regulate emissions of NO<INF>x in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). In addition, the final action on these rules 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) 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.
