Current through Register 2024 Notice Reg. No. 28, July 12, 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 shall
				  have a written closure plan. Until final closure is completed and certified in
				  accordance with section
				  66265.115, a copy of the most
				  current plan shall be kept at the facility and 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 who
				  is duly designated by the Director.
(b) Content of plan. The plan shall identify
				  steps necessary to perform partial or final closure of the facility at any
				  point during its active life and to perform final closure of the facility at
				  the end of its active life. The closure plan shall include, at least:
(1) a description of how and when each
				  hazardous waste management unit at the facility will be closed in accordance
				  with section
				  66265.111; and
(2) a description of how and when final
				  closure of the facility will be conducted in accordance with section
				  66265.111. 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 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, groundwater 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.
(8) all information
				  necessary to enable the Department to prepare an Initial Study for the closure
				  plan, which meets the requirements of Title 14, CCR section
				  15063, unless the Department has
				  determined that the closure plan is exempt from the requirements of the
				  California Environmental Quality Act pursuant to Title 14, CCR section
				  15061.
