Pub. Resources Code, § 25372.4

(a) Information provided to the division shall presumptively be confidential and not subject to public disclosure. The division shall not divulge or make known in any manner any information provided to it unless it determines both of the following:

(1) Public disclosure of the specific information would not result in unfair competitive disadvantage to the person supplying the information.

(2) Public disclosure of the specific information would not adversely affect market competition.

(b) Notwithstanding any other law, the division may disclose information deemed confidential under this subdivision to members of the commission, other divisions of the commission, the Attorney General, or the California Department of Tax and Fee Administration if the receiving entity agrees to keep the information confidential, except that the Attorney General may present the information to a court to support an enforcement action but shall submit confidential information under seal where permissible. If the Attorney General requests the assistance of the division in connection with any investigation, the division shall provide information to the Attorney General under this subdivision and any other assistance that is feasible.

(c) For purposes of the division’s annual reports under Section 25372.2, the division shall aggregate data or otherwise anonymize and generalize information as needed to mitigate the risk that public disclosure of the specific information would result in unfair competitive disadvantage to the person supplying the information or would adversely affect market competition.
