(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 paragraph (A) of this rule, 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 (rule 3745-68-10 of the Administrative Code).

(a) Include in the closure plan for the drip pad under rule 3745-66-12 of the Administrative Code both a plan for complying with paragraph (A) of this rule and a contingent plan for complying with paragraph (B) of this rule in case not all contaminated subsoils can be practicably removed at closure; and
(b) Prepare a contingent post-closure plan under rule 3745-66-18 of the Administrative Code for complying with paragraph (B) of this rule in case not all contaminated subsoils can be practicably removed at closure.
