The applicable requirements of articles 27, 28, and 28.5 of chapter 15 of this division;(B) Condition of containers. If a container holding hazardous waste is not in good condition, or if it begins to leak, the large quantity generator shall immediately transfer the hazardous waste from this container to a container that is in good condition, or immediately manage the waste in some other way that complies with the conditions for exemption of this section;(C) Compatibility of waste with container. The large quantity generator shall use a container made of or lined with materials that will not react with, and are otherwise compatible with, the hazardous waste to be stored, so that the ability of the container to contain the waste is not impaired;(D) Management of containers.1. A container holding hazardous waste shall always be closed during accumulation, except when it is necessary to add or remove waste.2. A container holding hazardous waste shall not be opened, handled, or stored in a manner which may rupture the container or cause it to leak.

At closure, the generator shall close the waste accumulation unit or facility in a manner that: a. Minimizes the need for further maintenance by controlling, minimizing, or eliminating, 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; andb. Removes or decontaminates all contaminated equipment, structures, and soil and any remaining hazardous waste residues from waste accumulation units including containment system components (e.g., pads, liners), contaminated soils and subsoils, bases, and structures and equipment contaminated with waste, unless section 66261.3(d) of this division applies.c. Any hazardous waste generated in the process of closing either the generator's facility or unit(s) accumulating hazardous waste shall be managed in accordance with all applicable standards of chapters 12, 13, 15 and 18 of this division, including removing any hazardous waste contained in these units within 90 days of generating it and managing these wastes in a hazardous waste permitted transfer, treatment, storage, and disposal facility or interim status facility.d. If the generator demonstrates that any contaminated soils and wastes cannot be practicably removed or decontaminated as required in subsection (a)(8)(B)1.b of this section, then the waste accumulation unit is considered to be a landfill and the generator shall close the waste accumulation unit and perform post-closure care in accordance with the closure and post-closure care requirements that apply to landfills (section 66265.310 of this division). In addition, for the purposes of closure, post-closure, and financial responsibility, such a waste accumulation unit is then considered to be a landfill, and the generator shall meet all of the requirements for landfills specified in articles 7 and 8 of chapter 15 of this division.(D) Closure performance standards for drip pad waste accumulation units. At closure, the generator shall comply with the closure requirements of subsections (a)(8)(B) and (a)(8)(C)1.a and c of this section, and subsections 66265.445(a) and (b) of this division.(E) The closure requirements of subsection (a)(8) of this section do not apply to satellite accumulation areas.(9) Land disposal restrictions. The large quantity generator shall comply with all applicable requirements under chapter 18 of this division.(b) Accumulation time limit extension. A large quantity generator that accumulates hazardous waste for more than 90 days is subject to the requirements of chapters 14, 15, 16, 18, and 20 of this division, or the notification requirements pursuant to Health and Safety Code section 25153.6, unless the generator has been granted an extension to the 90-day period. An extension may be granted by the Department if hazardous wastes must remain on site for longer than 90 days due to unforeseeable, temporary, and uncontrollable circumstances. An extension of up to 30 days may be granted at the discretion of the Department on a case-by-case basis. An extension may be granted pursuant to section 66262.35 if non-RCRA or RCRA-exempt hazardous wastes must remain on site for longer than 90 days.(c) Rejected load. A large quantity generator that sends a shipment of hazardous waste to a designated facility, with the understanding that the designated facility can accept and manage the waste and later receives that shipment back as a rejected load or residue in accordance with the manifest discrepancy provisions of sections 66264.72 or 66265.72 of this division, may accumulate the returned waste onsite in accordance with subsections (a) and (b) of this section. Upon receipt of the returned shipment, the generator shall: (1) Sign Item 18c of the manifest, if the transporter returned the shipment using the original manifest; or(2) Sign Item 20 of the manifest, if the transporter returned the shipment using a new manifest.(3) Submit a copy of the signed manifest to the Department within 30 days of receipt. Mail the legible manifest copy, specifically the Designated Facility-to-Destination State manifest copy (Page 1 of the manifest as provided in section 66262.21, subsection (d)) to: DTSC FACILITY MANIFESTS
P.O. BOX 3000, SACRAMENTO, CA
95812-3000
(d) The large quantity generator of the rejected hazardous waste shall label or mark the hazardous waste in a manner that indicates that it is rejected hazardous waste and shall include the date it was received by the generator. If the generator of the rejected hazardous waste commingles it with other hazardous wastes, the shorter of any applicable accumulation time limits shall apply to the commingled hazardous waste.(e) The 90-day accumulation time period, for purposes of subsections (a) or (b) of this section, begins when any amount of hazardous waste first begins to accumulate in that month.Cal.
