--- kind: "range" citation: "40 C.F.R. §§ 267.111–267.115" title: "40" from: "267.111" to: "267.115" count: 5 url: "https://uscodex.org/cfr/40/267.111..267.115" --- # §267.111. What general standards must I meet when I stop operating the unit? You must close the storage and treatment units in a manner that: - (a) Minimizes the need for further maintenance; and - (b) Controls, minimizes, or eliminates, to the extent necessary to protect human health and the environment, post-closure escape of hazardous waste, hazardous constituents, leachate, contaminated run-off, or hazardous waste decomposition products to the ground or surface waters or to the atmosphere; and - (c) Meets the closure requirements of this subpart and the requirements of §§ [267.176](/cfr/40/267.176.md), [267.201](/cfr/40/267.201.md), and [267.1108](/cfr/40/267.1108.md). If you determine that, when applicable, the closure requirements of [§ 267.201(tanks)](/cfr/40/267.201.md?p=tanks) or [§ 267.1108](/cfr/40/267.1108.md) (containment buildings) cannot be met, then you must close the unit in accordance with the requirements that apply to landfills ([§ 264.310](/cfr/40/264.310.md)). In addition, for the purposes of post-closure and financial responsibility, such a tank system or containment building is then considered to be a landfill, and you must apply for a post-closure care permit in accordance with [40 CFR part 270](/cfr/40/part270.md). # §267.112. What procedures must I follow? - (a) To close a facility, you must follow your approved closure plan, and follow notification requirements. - (1) Your closure plan must be submitted at the time you submitted your Notice of Intent to operate under a standardized permit. Final issuance of the standardized permit constitutes approval of the closure plan, and the plan becomes a condition of the RCRA standardized permit. - (2) The Director's approval of the plan must ensure that the approved plan is consistent with §§ [267.111 through 267.115](/cfr/40/267.111..267.115.md), [267.176](/cfr/40/267.176.md), [267.201](/cfr/40/267.201.md), and [267.1108](/cfr/40/267.1108.md). - (b) **Satisfy the requirements for content of closure plan.** The closure plan must identify steps necessary to perform partial and/or final closure of the facility. The closure plan must include, at least: - (1) A description of how each hazardous waste management unit at the facility subject to this subpart will be closed following [§ 267.111](/cfr/40/267.111.md). - (2) A description of how final closure of the facility will be conducted in accordance with [§ 267.111](/cfr/40/267.111.md). The description must identify the maximum extent of the operations which will be unclosed during the active life of the facility. - (3) An estimate of the maximum inventory of hazardous wastes ever on site during the active life of the facility and a detailed description of the methods you will use during partial and/or final closure, such as methods for removing, transporting, treating, storing, or disposing of all hazardous wastes, and identification of the type(s) 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 or final closure. These might include procedures for cleaning equipment and removing contaminated soils, methods for sampling and testing surrounding soils, and criteria for determining the extent of decontamination required to satisfy the closure performance standard; - (5) A detailed description of other activities necessary during the closure period to ensure that partial or final closure satisfies the closure performance standards. - (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 allow tracking of progress of partial or final closure. - (7) For facilities that use trust funds to establish financial assurance under [§ 267.143](/cfr/40/267.143.md) and that are expected to close prior to the expiration of the permit, an estimate of the expected year of final closure. - (c) You may submit a written notification to the Director for a permit modification to amend the closure plan at any time prior to the notification of partial or final closure of the facility, following the applicable procedures in [40 CFR 124.211](/cfr/40/124.211.md). - (1) Events leading to a change in the closure plan, and therefore requiring a modification, may include: - (i) A change in the operating plan or facility design; - (ii) A change in the expected year of closure, if applicable; or - (iii) In conducting partial or final closure activities, an unexpected event requiring a modification of the approved closure plan. - (2) The written notification or request must include a copy of the amended closure plan for review or approval by the Director. The Director will approve, disapprove, or modify this amended plan in accordance with the procedures in 40 CFR [124.211](/cfr/40/124.211.md) and [270.320](/cfr/40/270.320.md). - (d) **Notification before final closure.** - (1) You must notify the Director in writing at least 45 days before the date that you expect to begin final closure of a treatment or storage tank, container storage area, or containment building. - (2) The date when you “expect to begin closure” must be no later than 30 days after the date that any hazardous waste management unit receives the known final volume of hazardous wastes. - (3) If your facility's permit is terminated, or if you are otherwise ordered, by judicial decree or final order under [section 3008](/cfr/40/3008.md) of RCRA, to cease receiving hazardous wastes or to close, then the requirements of this [paragraph (d)](#d) do not apply. However, you must close the facility following the deadlines established in [§ 267.115](/cfr/40/267.115.md). # §267.113. Will the public have the opportunity to comment on the plan? - (a) The Director will provide you and the public, when the draft standardized permit is public noticed, the opportunity to submit written comments on the plan and to the draft permit as allowed by [40 CFR 124.208](/cfr/40/124.208.md). The Director will also, in response to a request or at his/her own discretion, hold a public hearing whenever such a hearing might clarify one or more issues concerning the closure plan, and the permit. - (b) The Director will give public notice of the hearing 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. # §267.114. Reserved # §267.115. After I stop operating, how long until I must close? - (a) Within 90 days after the final volume of hazardous waste is sent to a unit, you must treat or remove from the unit all hazardous wastes following the approved closure plan. - (b) You must complete final closure activities in accordance with the approved closure plan within 180 days after the final volume of hazardous wastes is sent to the unit. The Director may approve an extension of 180 days to the closure period if you comply with all applicable requirements for requesting a modification to the permit and demonstrate that: - (1) The final closure activities will take longer than 180 days to complete due to circumstances beyond your control, excluding ground water contamination; and - (2) You have taken and will continue to take all steps to prevent threats to human health and the environment from the unclosed, but not operating hazardous waste management unit or facility, including compliance with all applicable permit requirements. - (3) The demonstration must be made at least 30 days prior to the expiration of the initial 180-day period. - (c) Nothing in this section precludes you from removing hazardous wastes and decontaminating or dismantling equipment in accordance with the approved final closure plan at any time before or after notification of final closure.
