Section 66265.112 - Closure Plan; Amendment of Plan(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.(c) Amendment of plan. The owner or operator may amend the closure plan at any time prior to the notification of partial or final closure of the facility. An owner or operator with an approved closure plan shall submit a written request to the Department to authorize a change to the approved closure plan. The written request shall include a copy of the amended closure plan for approval by the Department. (1) The owner or operator shall amend the closure plan whenever:(A) changes in operating plans or facility design affect the closure plan, or(B) there is a change in the expected year of closure, or(C) in conducting partial or final closure activities, unexpected events require a modification of the closure plan.(2) The owner or operator shall amend the closure plan at least 60 days prior to the proposed change in facility design or operation, or no later than 60 days after an unexpected event has occurred which has affected the closure plan. If an unexpected event occurs during the partial or final closure period, the owner or operator shall amend the closure plan no later than 30 days after the unexpected event. These provisions also apply to owners or operators of surface impoundments and waste piles who intended to remove all hazardous wastes at closure, but are required to close as landfills in accordance with section 66265.310.(3) An owner or operator with an approved closure plan shall submit the modified plan to the Department at least 60 days prior to the proposed change in facility design or operation, or no later than 60 days after an unexpected event has occurred which has affected the closure plan. If an unexpected event occurs during the partial or final closure period, the owner or operator shall submit the modified plan no later than 30 days after the unexpected event. These provisions also apply to owners or operators of surface impoundments and waste piles who intended to remove all hazardous wastes at closure but are required to close as landfills in accordance with section 66265.310. If the amendment to the plan is a Class 2 or 3 modification according to the criteria in section 66270.42, the modification to the plan will be approved according to the procedures in section 66265.112(d)(4).(4) The Department may request modifications to the plan under the conditions described in subsection (c)(1) of this section. An owner or operator with an approved closure plan shall submit the modified plan within 60 days of the request from the Department, or within 30 days if the unexpected event occurs during partial or final closure. If the amendment is considered a Class 2 or 3 modification according to the criteria in section 66270.42, the modification to the plan will be approved in accordance with the procedures in section 66265.112(d)(4).(d) Notification of partial closure and final closure. (1) The owner or operator shall submit the closure plan to the Department at least 180 days prior to the date on which the owner or operator expects to begin closure of the first surface impoundment, waste pile, land treatment, or landfill unit, or final closure if it involves such a unit, whichever is earlier. The owner or operator shall submit the closure plan to the Department at least 180 days prior to the date on which the owner or operator expects to begin partial or final closure of a boiler or industrial furnace. The owner or operator shall submit the closure plan to the Department at least 180 days prior to the date on which the owner or operator expects to begin final closure of a facility with only tanks or containers used for transfer, treatment or storage, or incinerator units. An owner or operator with an approved closure plan shall notify the Department in writing at least 60 days prior to the date on which the owner or operator expects to begin closure of a surface impoundment, waste pile, landfill, or land treatment unit, or final closure of a facility involving such a unit. Owners or operators with approved closure plans shall notify the Department in writing at least 45 days prior to the date on which the owner or operator expects to begin partial or final closure of a boiler or industrial furnace. An owner or operator with an approved closure plan shall notify the Department in writing at least 45 days prior to the date on which the owner or operator expects to begin final closure of a facility with only tanks or containers used for transfer, treatment or storage, or incinerator units.(2) The date when the owner or operator "expects to begin closure" shall be either no later than the date on which any hazardous waste management unit receives the known final volume of hazardous wastes or, if there is a reasonable possibility that the hazardous waste management unit will receive additional hazardous wastes, no later than one year after the date on which the unit received the most recent volume of hazardous waste. The Department may approve an extension to this one-year limit if the owner or operator of a hazardous waste management unit demonstrates to the satisfaction of the Department that the hazardous waste management unit or facility has the capacity to receive additional hazardous wastes, the owner or operator has taken, and will continue to take, all steps necessary to comply with all interim status requirements, and the extension will not pose a threat to human health and the environment.(3) For units meeting the requirements of section 66265.113(d), the date when the owner or operator "expects to begin closure" shall be no later than the date on which the hazardous waste management unit receives the known final volume of non-hazardous wastes, or if there is a reasonable possibility that the hazardous waste management unit will receive additional non-hazardous wastes, no later than one year after the date on which the unit received the most recent volume of non-hazardous wastes. If the owner or operator can demonstrate to the Department that the hazardous waste management unit has the capacity to receive additional non-hazardous wastes and the owner or operator has taken, and will continue to take, all steps to prevent threats to human health and threats to the environment, including compliance with all applicable interim status requirements, the Department may approve an extension to this one-year limit. A facility operating under the requirements of section 66265.113(d) shall continue to be subject to the facility fee specified in Health and Safety Code, Division 20, section 25205.2(d), until the facility has complied with the requirements of section 66265.113(a). Health and Safety Code, Division 20, section 25205.2(d)(4) shall not apply to a facility operating pursuant to section 66265.113(d).(4) The owner or operator shall submit the closure plan to the Department no later than 15 days after: (A) termination of interim status except when a permit is issued simultaneously with termination of interim status; or(B) issuance of a judicial decree or final order under Health and Safety Code section 25358.3 or article 8 of chapter 6.5 of division 20 of the Health and Safety Code to cease receiving hazardous wastes or close.(5) The Department will provide the owner or operator and the public, through a newspaper notice, the opportunity to submit written comments on the plan and request modifications to the plan no later than 30 days from the date of the notice. The Department will also, in response to a request or at the Department's own discretion, hold a public hearing whenever such a hearing might clarify one or more issues concerning a closure plan. The Department will give public notice of the hearing at least 30 days before it occurs. Public notice of the hearing may be given at the same time as notice of the opportunity for the public to submit written comments, and the two notices may be combined. The Department will approve, modify, or disapprove the plan within 90 days of its receipt. If the Department does not approve the plan the Department shall provide the owner or operator with a detailed written statement of reasons for the refusal and the owner or operator shall modify the plan or submit a new plan for approval within 30 days after receiving such written statement. The Department will approve or modify this plan in writing within 60 days. If the Department modifies the plan, this modified plan becomes the approved closure plan. The Department shall assure that the approved plan is consistent with sections 66265.111 through 66265.115 and the applicable requirements of article 6 of this chapter and sections 66265.197, 66265.228, 66265.258, 66265.280, 66265.310, 66265.351, 66265.381, 66265.404, and 66265.1102. A copy of the modified plan with a detailed statement of reasons for the modifications shall be mailed to the owner or operator.Cal. Code Regs. Tit. 22, § 66265.112
