Rule 3745-205-102 | Closure and post-closure care of containment buildings.
(A) At closure of a containment building, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components (liners, etc.), contaminated subsoils, and structures and equipment contaminated with waste and leachate, and must manage them as hazardous waste unless paragraph (D) of rule 3745-51-03 of the Administrative Code applies. The closure plan, closure activities, cost estimate for closure, and financial responsibility for containment buildings must meet all of the requirements specified in rules 3745-55-10 to 3745-55-20 and 3745-55-40 to 3745-55-51 of the Administrative Code.
(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 practicably removed or decontaminated, he must close the facility and perform post-closure care in accordance with the closure and post-closure requirements that apply to landfills (see rule 3745-57-10 of the Administrative Code). In addition, for the purposes of closure, post-closure, and financial responsibility, such a containment building is considered to be a landfill, and the owner or operator must meet all of the requirements for landfills specified in rules 3745-55-10 to 3745-55-20 and 3745-55-40 to 3745-55-51 of the Administrative Code.
