Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part V - Hazardous Wastes and Hazardous Materials › Subpart 1 - Department of Environmental Quality-Hazardous Waste › Chapter 43 - Interim Status › Subchapter F - Closure and Post-Closure › Section V-4381 - Closure Plan; Amendment of Plan

Current through Register Vol. 50, No. 6, June 20, 2024
A. Written Plan. By the effective dates of
					 these regulations, 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 LAC 33:V.4387, a copy of the most current plan
					 must be furnished to the administrative authority 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 administrative authority.
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 LAC 33:V.4379; and
2. a description of how final closure of the
					 facility will be conducted in accordance with LAC 33:V.4379. The description
					 must identify the maximum extent of the operation which will be unclosed during
					 the active life of the facility; and
3. the maximum inventory of hazardous wastes
					 ever on-site over the active life of the facility for a final closure, and/or
					 an estimate of the maximum inventory for a partial closure, and a detailed
					 description of the methods to be used during the partial and final closure,
					 including, but not limited to methods for removing, transporting, treating,
					 storing or disposing of all hazardous waste, identification of, and 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, 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 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
					 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 LAC 33:V.4403 or 4407 and whose
					 remaining operating life is less than 20 years, and for facilities without
					 approved closure plans; and
8. for
					 facilities where the administrative authority has applied alternative
					 requirements at a regulated unit under LAC 33:V.4367.E, 4377.D, and/or 4397.D,
					 either the alternative requirements applying to the regulated unit or a
					 reference to the enforceable document containing those alternative
					 requirements.
