Current through all regulations passed and filed through July 1, 2024
(A)
			 Written closure plan. On April 15, 1981, the owner or operator of a hazardous
			 waste management facility shall have a written closure plan. Until final
			 closure is completed and certified in accordance with rule
			 3745-66-15
			 of the Administrative Code, a copy of the most current closure plan shall be
			 furnished to the director upon request, including request by mail. In addition,
			 for facilities without approved closure plans, a copy of the most current
			 closure plan shall be provided during site inspections, on the day of
			 inspection, to any officer, employee, or representative of Ohio EPA who is duly
			 designated by the director.
(B)
			 Content of closure plan. The closure plan shall identify steps necessary to
			 perform partial or final closure of the facility at any point during the active
			 life of the facility. The closure plan shall include at least
			 :
(1) A description of how each hazardous waste
			 management unit at the facility will be closed in accordance with rule
			 3745-66-11
			 of the Administrative Code; and
(2) A description of how final closure of the
			 facility will be conducted in accordance with rule
			 3745-66-11
			 of the Administrative Code. The description shall identify the maximum extent
			 of the operation which will be unclosed during the active life of the
			 facility;
			 and
(3) An estimate of the
			 maximum inventory of hazardous wastes ever on-site over the active life of the
			 facility and a detailed description of the methods to be used during partial
			 and final closure, including, but not limited to, methods for removing,
			 transporting, treating, storing, or disposing of all hazardous waste,
			 identification of and the types of off-site hazardous waste management units to
			 be used, if applicable; and
(4)
			 A detailed description of the steps needed to remove or decontaminate all
			 hazardous waste residues and contaminated containment system components,
			 equipment, structures, and soils during partial and final closure including,
			 but not limited to, procedures for cleaning equipment and removing contaminated
			 soils, methods for sampling and testing surrounding soils, and criteria for
			 determining the extent of decontamination necessary to satisfy the closure
			 performance standard; and
(5)
			 A detailed description of other activities necessary during the partial and
			 final closure periods to ensure that all partial closures and final closure
			 satisfy the closure performance standards, including, but not limited to,
			 ground water monitoring, leachate collection, and run-on and run-off
			 control;
			 and
(6) A schedule for
			 closure of each hazardous waste management unit and for final closure of the
			 facility. The schedule shall include, at a minimum, the total time required to
			 close each hazardous waste management unit and the time required for
			 intervening closure activities which will allow tracking of the progress of
			 partial and final closure (for example, in the case of a landfill unit,
			 estimates of the time required to treat or dispose of all hazardous waste
			 inventory and of the time required to place a final cover shall be
			 included);
			 and
(7) An estimate of the
			 expected year of final closure for facilities that use trust funds to
			 demonstrate financial assurance under rule
			 3745-66-43
			 or
			 3745-66-45
			 of the Administrative Code and for which the remaining operating life is less
			 than twenty years, and for facilities without approved closure plans.
(8) For facilities where the director has
			 applied alternative requirements at a regulated unit under paragraph (F) of
			 rule
			 3745-54-90,
			 paragraph (D) of rule
			 3745-66-10,
			 or paragraph (D) of rule
			 3745-66-40
			 of the Administrative Code, either the alternative requirements that apply to
			 the regulated unit, or a reference to the enforceable document that contains
			 those alternative requirements.
