California Code, Health and Safety Code - HSC § 78885

(a) The department may prequalify bidders for remedial or removal actions taken pursuant to Section 78870 or 78875. The department may reject the bid of any prospective bidder that has not been prequalified.

(b) To prequalify bidders, the department shall adopt and apply a uniform system of rating bidders. In order to obtain information for that rating, the department may require from prospective bidders answers to questions, including, but not limited to, questions about the bidder's financial ability, the bidder's experience in removal and remedial action involving hazardous substances, the bidder's past safety record, and the bidder's past performance on federal, state, or local government projects. The department may also require prospective bidders to submit financial statements.

(c) The department shall utilize the business financial data and information submitted by a bidder pursuant to subdivision (b) only for the purposes of prequalifying bidders pursuant to this section and shall not otherwise disseminate this data or information.

(d) The system of rating bidders may be adopted by the department as emergency regulations in accordance with Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code, and for purposes of that chapter, when these regulations are adopted as emergency regulations pursuant to Section 11349.6 of the Government Code, the regulations shall be deemed to be necessary for the immediate preservation of the public peace, health and safety, and general welfare. It is the intent of the Legislature that emergency regulations adopted pursuant to this subdivision shall remain in effect until the regulations are adopted as final regulations, pursuant to Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code.
