Hawaii Administrative Rules › Title 11 - DEPARTMENT OF HEALTH › Subtitle 1 - GENERAL DEPARTMENTAL PROVISIONS › Chapter 265 - HAZARDOUS WASTE MANAGEMENT INTERIM STATUS STANDARDS FOR OWNERS OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE AND DISPOSAL FACILITIES › Subchapter G - CLOSURE AND POST-CLOSURE › Section 11-265-112 - Closure plan; amendment of plan

Current through June, 2024
(a) Written plan.
				  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 section 11-265-115, 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 department 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 section 11-265-111; and
(2) A description of how final closure of the
				  facility will be conducted in accordance with section 11-265-111. 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 period 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 section 11-265-143 or section 11-265-145 and whose remaining operating
				  life is less than twenty years, and for facilities without approved closure
				  plans.
