Cal. Health and Safety Code § 39915

On or before July 1, 2002, the state board, in consultation with air quality management districts, air pollution control districts, and the Independent System Operator, shall establish a schedule for the retrofit of electric generation facilities pursuant to retrofit criteria and procedures established under the federal Clean Air Act (42 U.S.C. Section 7401 et seq.) or this division. The schedule shall require completion of any mandated retrofits by December 31, 2004, or such later date as the state board, in consultation with the Independent System Operator, air pollution control districts, air quality management districts, and the owners and operators of electrical generating facilities determines is necessary to maintain electric system reliability. Nothing in this section is intended to require the retrofit of a generation facility that could not be required to be retrofitted by an air quality management district or air pollution control district under the law in effect on the effective date of the act adding this chapter during the 2001-02 First Extraordinary Session. The state board shall suspend the deadline for the completion of a retrofit of an electrical generation unit scheduled pursuant to this section if it determines all of the following: (a) The owner of the generation unit proposes to replace or repower the generation unit in a manner that complies with all applicable laws and regulations. (b) The owner has filed the necessary applications for permits for such replacement or repower prior to the suspension of the deadline for the completion of the required retrofits. (c) The owner is diligently proceeding with the replacement or repower of the unit and the state board determines that the replacement or repower will be completed.
