California Code, Government Code - GOV § 15150

(a) It is the intent of the Legislature that the Department of Justice shall commence to operate under this chapter as soon as feasible, but until such time, the department shall continue to operate under Article 8 (commencing with Section 13240) of Chapter 2, Part 3, Division 3, Title 2 of this code, and Chapter 2 (commencing with Section 15100) of this part.  Accordingly, the department shall not discontinue service to any connection point to which it is required to furnish services at state expense until it has made the determination, has given notice, and the notice period has elapsed, as provided in subdivision (b).

(b) At such time as the Attorney General concludes that he can furnish service to one location in any county in compliance with the requirements of Section 15161, he shall so certify and shall send notice of such certification to each agency in the county connected with the state system.  Thirty days after the sending of such notice, service to any connection point in the county other than the one location selected pursuant to Section 15161 shall no longer be at state expense.
