§ 66264.575. Closure.

(a) At closure, the owner or operator shall remove or decontaminate all waste residues, contaminated containment system components (pad, liners, etc.), contaminated subsoils, and structures and equipment contaminated with waste and leakage, and manage them as hazardous waste.

(b) If, after removing or decontaminating all residues and making all reasonable efforts to effect removal or decontamination of contaminated components, subsoils, structures, and equipment as required in subsection (a) of this section, the owner or operator finds that not all contaminated subsoils can be practically removed or decontaminated, the owner or operator shall close the facility and perform post-closure care in accordance with closure and post-closure care requirements that apply to landfills (section 66264.310). For permitted units, the requirement to have a permit continues throughout the post-closure period. In addition, for the purposes of closure, post-closure, and financial responsibility, such a drip pad is then considered to be a landfill, and the owner or operator shall meet all of the requirements for landfills specified in articles 7 and 8 of this chapter.

(c)(1) The owner or operator of an existing drip pad, as defined in section 66264.570, that does not comply with the liner requirements of section 66264.573(b)(1) shall:

(A) include in the closure plan for the drip pad under section 66264.112 both a plan for complying with subsection (a) of this section and a contingent plan for complying with subsection (b) of this section in case not all contaminated subsoils can be practicably removed at closure; and

(B) prepare a contingent post-closure plan under section 66264.118 for complying with subsection (b) of this section in case not all contaminated subsoils can be practicably removed at closure;

(2) the cost estimates calculated under sections 66264.112 and 66264.144 for closure and post-closure care of a drip pad subject to this chapter shall include the cost of complying with the contingent closure plan and the contingent post-closure plan, but are not required to include the cost of expected closure under subsection (a) of this section.
