Cal. Pub. Res. Code § 43214

(a) The board shall develop performance standards for evaluating certified local enforcement agencies and shall periodically review each certified enforcement agency and its implementation of the permit, inspection, and enforcement program. The board’s review shall include periodic inspections of solid waste facilities and disposal sites within the jurisdiction of each enforcement agency for the purpose of evaluating whether the enforcement agency is appropriately applying and enforcing state minimum standards within its jurisdiction.
(b) Following initial certification of an enforcement agency by the board, the board shall conduct a performance review of the enforcement agency every three years, or more frequently as determined by the board.
(c) In conducting performance reviews of enforcement agencies, the board shall, based on the performance standards developed pursuant to subdivision (a), determine whether each enforcement agency is in compliance with the requirements of this article and the regulations adopted to implement this article. If the board finds that an enforcement agency is not fulfilling its responsibilities pursuant to this article and if the board also finds that this lack of compliance has contributed to significant noncompliance with state minimum standards at solid waste facilities or disposal sites within the jurisdiction of the enforcement agency, the board shall withdraw its approval of designation pursuant to Sections 43215 and 43216. Notwithstanding Sections 43215 and 43216, if the board finds that conditions at solid waste facilities or disposal sites within the jurisdiction of the enforcement agency threaten public health and safety or the environment, the board shall, within 10 days of notifying the enforcement agency, become the enforcement agency until another enforcement agency is designated locally and certified by the board.
(d) The board shall find that an enforcement agency is not fulfilling its responsibilities pursuant to this article, and may take action as prescribed by subdivision (c), if the board, in conducting its performance review, makes one or more of the following findings with regard to compliance with this part and Part 5 (commencing with Section 45000):
1. (1) The enforcement agency has failed to exercise due diligence in the inspection of solid waste facilities and disposal sites.
2. (2) The enforcement agency has intentionally misrepresented the results of inspections.
3. (3) The enforcement agency has failed to prepare, or cause to be prepared, permits, permit revisions, or closure and postclosure maintenance plans.
4. (4) The enforcement agency has approved permits, permit revisions, or closure and postclosure maintenance plans that are not consistent with this part and Part 5 (commencing with Section 45000).
5. (5) The enforcement agency has failed to take appropriate enforcement actions.
6. (6) The enforcement agency has failed to comply with, or has taken actions that are inconsistent with, or that are not authorized by, this division or the regulations adopted by the board pursuant to this division. However, nothing in this paragraph is intended to affect the authority of enforcement agencies pursuant to subdivision (e) of Section 43209.
