Section 110(h) of the Clean Air Act, as amended in 1990 (the "Act"), requires EPA by November 15, 1995, and every three years thereafter, to assemble the requirements of the federally-enforceable State Implementation Plans (SIPs) in each State and to publish notice in the Federal Register of the availability of such documents. This notice of availability fulfills the three-year requirement of making these SIP compilations for each State available to the public.
