Pub. Util. Code, § 8325

(a) Each electrical corporation owning, in whole or in part, or operating nuclear facilities, located in California or elsewhere, shall establish an externally managed, segregated fund for the purposes of this chapter. In addition, each electrical corporation may establish other funds, as appropriate, for payment of decommissioning costs of nuclear facilities.

(b) The externally managed, segregated fund established pursuant to subdivision (a) shall be a fund which qualifies for a tax deduction pursuant to Section 468A of the United States Internal Revenue Code, and applicable regulations of the Internal Revenue Service adopted pursuant thereto, if that tax treatment is determined by the commission to be in the best long-term interests of the customers of the electrical utility.

(c) The commission shall authorize an electrical corporation to collect sufficient revenues in rates to make the maximum contributions to the fund established pursuant to Section 468A of the United States Internal Revenue Code and applicable regulations, that are deductible for federal and state income tax purposes, and to otherwise recover the revenue requirements associated with reasonable and prudent decommissioning costs of the nuclear facilities for purposes of making contributions into other funds established pursuant to subdivision (a).

(d) Notwithstanding any other provision of this section, an electrical utility, which is a publicly owned public utility subject to the jurisdiction and control of its board, shall establish and may manage a separate fund for purposes of this chapter. The board shall provide that the amounts of all payments into this fund are recoverable through the utility’s electric rates.
