(a) With the exceptions set forth in this section, the Administrator approves the New York State Implementation Plan (SIP) for the attainment and maintenance of the national standards under section 110(a)(2) of the Clean Air Act. Furthermore, the Administrator finds that the plan satisfies all requirements of Part D, Title I of the Clean Air Act, as amended in 1977. In addition, continued satisfaction of the requirements of Part D for the ozone element of the SIP depends on the adoption and submittal of requirements for reasonable available control technology (RACT) by January 1985 and adoption and submittal by each subsequent January of additional RACT requirements for sources covered by Control Techniques Guidelines (CTGs) issued by the previous January.
