Text: 57 Phoenix also argues that the interpretation of the CAA argued by Appellants and the EPA generates confusion because it forces a city to track the EPA's past actions to glean what the EPA deems to be currently enforceable measures. But Phoenix overstates the difficulty of its task. Under present EPA policy, the city need only look to the C.F.R., relevant portions of the Federal Register, and its state's own submissions to the EPA to discover the presently enforceable SIP. See also 42 U.S.C. Sec. 7410(h) (1994) (requiring the EPA to assemble and publish [by Nov. 15, 1995, and again every three years thereafter] a comprehensive document for each State setting forth all requirements of the applicable implementation plan for such State).
