Cal. Health & Safety Code § 79055

(a) Except as provided in Sections 79060 and 79065, no money shall be expended from the state account for removal or remedial actions on any site selected for inclusion on the list established pursuant to Article 5 (commencing with Section 78760) of Chapter 4, unless the department first takes both of the following actions:
1. (1) The department issues one of the following orders or enters into the following agreement:
  1. (A) The department issues an order specifying a schedule for compliance or correction pursuant to Section 25187.
  2. (B) The department issues an order establishing a schedule for removing or remedying the release of a hazardous substance at the site, or for correcting the conditions that threaten the release of a hazardous substance. The order shall include, but is not limited to, requiring specific dates by which necessary corrective actions shall be taken to remove the threat of a release, or dates by which the nature and extent of a release shall be determined and the site adequately characterized, a remedial action plan shall be prepared, the remedial action plan shall be submitted to the department for approval, and a removal or remedial action shall be completed.
  3. (C) The department enters into an enforceable agreement with a potentially responsible party for the site that requires the party to take necessary corrective action to remove the threat of the release, or to determine the nature and extent of the release and adequately characterize the site, prepare a remedial action plan, and complete the necessary removal or remedial actions, as required in the approved remedial action plan.
2. (2) The department determines, in writing, that the potentially responsible party or parties for the hazardous substance release site have not complied with all of the terms of an order issued pursuant to subparagraph (A) or (B) of paragraph (1) or an agreement entered into pursuant to subparagraph (C) of paragraph (1). Before the department determines that a potentially responsible party is not in compliance with the order or agreement, the department shall give the potentially responsible party written notice of the proposed determination and an opportunity to correct the noncompliance or show why the order should be modified. After the department has made the final determination that a potentially responsible party is not in compliance with the order or agreement, the department may expend money from the state account for a removal or remedial action.
(b) Any enforceable agreement entered into pursuant to this section may provide for the execution and recording of a written instrument that imposes an easement, covenant, restriction, or servitude, or combination thereof, as appropriate, upon the present and future uses of the site. The instrument shall provide that the easement, covenant, restriction, or servitude, or combination thereof, as appropriate, is subject to the variance or removal procedures specified in Sections 25223 and 25224. Notwithstanding any other provision of law, an easement, covenant, restriction, or servitude, or any combination thereof, as appropriate, executed pursuant to this section and recorded so as to provide constructive notice runs with the land from the date of recordation, is binding upon all of the owners of the land, their heirs, successors, and assignees, and the agents, employees, or lessees of the owners, heirs, successors, and assignees, and is enforceable by the department pursuant to Article 8 (commencing with Section 25180) of Chapter 6.5 of Division 20.
