(a)
On November 13, 1992, California submitted a commitment to prepare a revision to the California State Implementation Plan (SIP) for the California ozone nonattainment areas to address the requirement in section 182(c)(4)(B) of the 1990 Clean Air Act Amendments that requires the States to develop a SIP revision for all ozone nonattainment areas classified as serious and above to opt-out of the Clean-Fuel Fleet Program by submitting for EPA approval a substitute program(s) resulting in as much or greater long-term reductions in ozone-producing and toxic air emissions. The State submittal contained an interim milestone to supply more accurate emission reduction data demonstrating equivalence no later than one year after the publication date of the Federal Register notice approving the State's committal SIP revision. California is required to submit the final SIP revision by May 15, 1994. The State held a public meeting on this committal SIP on March 17, 1992. The California SIP revisions are met automatically when the SIP revision concerns a regulation previously adopted by the Board.
