Pub. Resources Code, § 43040

(a) The board shall adopt standards and regulations requiring that, as a condition for the issuance, modification, revision, or review of a solid waste facilities permit for a disposal facility, the operator of the disposal facility shall provide assurance of adequate financial ability to respond to personal injury claims and public or private property damage claims resulting from the operations of the disposal facility which occur before closure.

(b) To the extent practicable and consistent with federal law and regulations, the board and the state water board shall, on or before January 1, 1994, develop a work plan for combining financial assurance requirements for operating liability with financial assurance requirements for corrective actions into one mechanism which provides appropriate coverage for both purposes.
