Current through June, 2024
(a) Written plan.
					 By May 19, 1981, or by six months after the effective date of the rule that
					 first subjects a facility to provisions of this section, the owner or operator
					 of a hazardous waste management facility must have a written closure plan.
					 Until final closure is completed and certified in accordance with §
					 265.115, a copy of the most current plan must be furnished to the director upon
					 request, including request by mail. In addition, for facilities without
					 approved plans, it must also be provided during site inspections, on the day of
					 inspection, to any officer, employee, or representative of the state department
					 of health who is duly designated by the director.
(b) Content of plan. The plan must identify
					 steps necessary to perform partial and/or final closure of the facility at any
					 point during its active life. The closure plan must include, at least:
(1) A description of how each hazardous waste
					 management unit at the facility will be closed in accordance with §
					 265.111; and
(2) A description of
					 how final closure of the facility will be conducted in accordance with §
					 265.111. The description must 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 type(s) of off-site hazardous waste management unit(s) 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 must
					 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 must be included.); and
(7) An estimate of the expected year of final
					 closure for facilities that use trust funds to demonstrate financial assurance
					 under § 265.143 or § 265.145 and whose 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
					 §§ 265.90(f), 265.110(d), and/or 265.140(d), either the alternative
					 requirements applying to the regulated unit, or a reference to the enforceable
					 document containing those alternative requirements.
