California Code, Revenue and Taxation Code - RTC § 2209

(a) By the Governor, or

(b) By any officer or official serving at the pleasure of the Governor, or

(c) By any agency, department, board or commission of state government; provided that the term “executive order” shall not include any order, plan, requirement, rule or regulation issued by the State Water Resources Control Board or by any regional water quality control board pursuant to Division 7 (commencing with Section 13000) of the Water Code.

It is the intent of the Legislature that the State Water Resources Control Board and regional water quality control boards will not adopt enforcement orders against publicly owned dischargers which mandate major waste water treatment facility construction costs unless federal financial assistance and state financial assistance pursuant to the Clean Water Bond Act of 1970 and 1974, is simultaneously made available.

“Major” means either a new treatment facility or an addition to an existing facility, the cost of which is in excess of 20 percent of the cost of replacing the facility.
