Current through June 24, 2024
(1) WRITTEN PLAN.
				  By February 1, 1982, or by 6 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 shall have a written closure plan.
				  Until final closure is completed and certified in accordance with s.
				  NR
				  665.0115, a copy of the most current plan shall be
				  furnished to the department upon request, including request by mail. In
				  addition, for facilities without approved plans, it shall also be provided
				  during site inspections, on the day of inspection, to any officer, employee or
				  representative of the department.
(2) CONTENT OF PLAN. The plan shall identify
				  steps necessary to perform partial or final closure of the facility, or both,
				  at any point during its active life. The closure plan shall include, at least
				  all of the following:
(a) A description of
				  how each hazardous waste management unit at the facility will be closed in
				  accordance with s.
				  NR
				  665.0111.
(b) A description of how final closure of the
				  facility will be conducted in accordance with s.
				  NR
				  665.0111. The description shall identify the maximum
				  extent of the operation which will be unclosed during the active life of the
				  facility.
(c) 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.
(d) 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.
(e) A
				  detailed description of other activities necessary during the partial and final
				  closure period to ensure that all partial closures and final closure satisfy
				  the closure performance standards, including, but not limited to, groundwater
				  monitoring, leachate collection and run-on and run-off control.
(f) 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.).
(g) An estimate of the expected year of final
				  closure for facilities that use trust funds to demonstrate financial assurance
				  under s.
				  NR
				  665.0143 or 665.0145 and whose remaining operating
				  life is less than 20 years, and for facilities without approved closure
				  plans.
(h) For facilities where the
				  department has applied alternative requirements at a regulated unit under s.
				  NR
				  665.0090(6), 665.0110(4) or
				  665.0140(4), either the alternative requirements applying to the regulated
				  unit, or a reference to the enforceable document containing those alternative
				  requirements.
