Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Written Plan. Within 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
				725.215,
				a copy of the most current plan must be furnished to the Agency 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 Agency.
b) Content of Plan. The plan must identify
				the steps necessary to perform partial or final closure of the facility at any
				point during its active life. The closure plan must include the following
				minimal information:
1) A description of how
				each hazardous waste management unit at the facility will be closed in
				accordance with Section
				725.211;
2) A description of how final closure of the
				facility will be conducted in accordance with Section 725.211. The description
				must identify the maximum extent of the operation that will be unclosed during
				the active life of the facility;
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, and identification of and the types of off-site hazardous waste
				management units to be used, if applicable;
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;
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, groundwater monitoring, leachate collection, and
				run-on and run-off control;
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 that 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.);
7) An estimate of the
				expected year of final closure for facilities that use trust funds to
				demonstrate financial assurance under Section
				725.243
				or
				725.245
				and whose remaining operating life is less than twenty years, and for
				facilities without approved closure plans; and
8) For a facility where alternative
				requirements are established at a regulated unit under Section
				725.190(f),
				725.210(d),
				or
				725.240(d),
				as provided under 35 Ill. Adm. Code
				703.161,
				either the alternative requirements applying to the regulated unit or a
				reference to the enforceable document containing those alternative
				requirements.
