Final Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, Bay Area Air Quality Management District

EPA is finalizing limited approval and limited disapproval of revisions to the California State Implementation Plan (SIP) proposed in the Federal Register on November 6, 1998. This limited approval and limited disapproval action will incorporate portions of Rules 1, 2 and 4 of Regulation 2--Permits, for the Bay Area Air Quality Management District (BAAQMD or the ``District'') into the federally approved State Implementation Plan (SIP). The intended effect of finalizing this limited approval and limited disapproval of these rules is to strengthen the federally approved SIP by incorporating these updated provisions and to satisfy Federal requirements for an approvable nonattainment area NSR SIP for the District. Thus, EPA is finalizing simultaneous limited approval and limited disapproval as a revision into the California SIP under provisions of the Act regarding EPA action on SIP submittals, and general rulemaking authority. While strengthening the SIP, this revision contains deficiencies which the BAAQMD must address before EPA can grant full approval under Section 110(k)(3).
