52.2473—Approval status.
With the exceptions set forth in this subpart, the Administrator approves Washington's plan for the attainment and maintenance of National Standards under section 110 of the Clean Air Act. The regulations included in the SIP (See Table 52.2479) are applicable statewide unless otherwise noted in the regulation itself. Furthermore, the Administrator finds that the plan as identified in § 52.2470 satisfies requirements of Part D, Title 1, of the Clean Air act as amended in 1977, except as noted in the following sections. Continued satisfaction of the requirements of Part D for the ozone portion of the SIP depends on the adoption and submittal of RACT requirements by July 1, 1980 for the sources covered by CTGs issued between January 1978 and January 1979 and adoption and submittal by each subsequent January of additional RACT requirements for sources covered by CTGs issued by the previous January. New source review permits pursuant to section 173 of CAA will not be deemed valid by EPA unless the provisions of Section V of the emission offset interpretive rule published on January 16, 1979 ( 44 FR 3274) are met.
