NR 662.017(1)(h)1.1. ‘Notification for closure of a waste accumulation unit.’ A large quantity generator shall perform one of the following actions when closing a waste accumulation unit: NR 662.017(1)(h)1.a.a. Place a notice in the operating record within 30 days after closure identifying the location of the unit within the facility. NR 662.017(1)(h)1.b.b. Meet the closure performance standards of subd. 3. for container, tank, and containment building waste accumulation units or subd. 4. for drip pads and notify the department following the procedures in subd. 2. b. for the waste accumulation unit. If the waste accumulation unit is subsequently reopened, the generator may remove the notice from the operating record. NR 662.017(1)(h)2.a.a. Notify the department using form 8700-12 no later than 30 days prior to closing the facility. NR 662.017(1)(h)2.b.b. Notify the department using form 8700-12 within 90 days after closing the facility that it has complied with the closure performance standards of subd. 3. or 4. If the facility cannot meet the closure performance standards of subd. 3. or 4., notify the department using form 8700-12 that it will close as a landfill under s. NR 665.0310 in the case of a container, tank or containment building unit, or for a facility with drip pads, notify the department using form 8700-12 that it will close under the standards specified in s. NR 665.0445 (2). NR 662.017(1)(h)2.c.c. A large quantity generator may request additional time to clean close, but it shall notify the department using form 8700-12 within 75 days after the date provided in subd. 2. a. to request an extension and provide an explanation as to why the additional time is required. NR 662.017(1)(h)3.3. ‘Closure performance standards for container, tank systems, and containment building waste accumulation units.’ At closure, the generator shall close the waste accumulation unit or facility in a manner that meets all of the following: NR 662.017(1)(h)3.a.a. Minimizes the need for further maintenance by controlling, minimizing, or eliminating, to the extent necessary to protect human health and the environment, the 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. NR 662.017(1)(h)3.b.b. Removes or decontaminates all contaminated equipment, structures and soil and any remaining hazardous waste residues from waste accumulation units including containment system components, contaminated soils and subsoils, bases, and structures and equipment contaminated with waste, unless s. NR 661.0003 (4) applies. NR 662.017(1)(h)3.c.c. Any hazardous waste generated in the process of closing either the generator’s facility or units accumulating hazardous waste shall be managed in accordance with all applicable standards under chs. NR 662, 663, 665 and 668, including removing any hazardous waste contained in these units within 90 days of generating it and managing these wastes in a RCRA Subtitle C hazardous waste permitted treatment, storage and disposal facility or interim status facility. NR 662.017(1)(h)3.d.d. If the generator demonstrates that any contaminated soils and wastes cannot be practicably removed or decontaminated as required in subd. 3. b., 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 under s. NR 665.0310. In addition, for the purposes of closure, post-closure, and financial responsibility, the waste accumulation unit is then considered to be a landfill, and the generator shall meet all of the requirements for landfills specified in subchs. G and H of ch. NR 665. NR 662.017(1)(h)4.4. ‘Closure performance standards for drip pad waste accumulation units.’ At closure, the generator shall comply with the closure requirements of subds. 2. and 3.a. and c. and s. NR 665.0445 (1) and (2). NR 662.017(1)(h)5.5. ‘Applicability of closure performance standards to satellite accumulation areas.’ The closure requirements of this paragraph do not apply to satellite accumulation areas. NR 662.017(1)(i)(i) Land disposal restrictions. The large quantity generator complies with all applicable requirements under ch. NR 668. NR 662.017(2)(2) Accumulation time limit extension. A large quantity generator who accumulates hazardous waste for more than 90 days is subject to the requirements under chs. NR 664 to 668 and 670, and the notification requirements under s. NR 660.07, unless it 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 unforeseen, temporary, and uncontrollable circumstances. A one-time extension of up to 30 days, per occurrence, may be granted at the discretion of the department on a case-by-case basis. NR 662.017(3)(3) Accumulation of f006 waste. A large quantity generator that also generates wastewater treatment sludges from electroplating operations that meet the listing description for the EPA hazardous waste number F006, may accumulate F006 waste on-site for more than 90 days, but not more than 180 days without being subject to chs. NR 664 to 667 and 670, and the notification requirements under s. NR 660.07, provided that it complies with all of the following additional conditions for exemption: NR 662.017(3)(a)(a) The large quantity generator has implemented pollution prevention practices that reduce the amount of any hazardous substances, pollutants, or contaminants entering F006 or otherwise released to the environment prior to its recycling. NR 662.017(3)(b)(b) The F006 waste is legitimately recycled through metals recovery. NR 662.017(3)(c)(c) No more than 20,000 kilograms of F006 waste is accumulated on-site at any one time. NR 662.017(3)(d)(d) The F006 waste is managed in accordance with all of the following: NR 662.017(3)(d)1.a.a. If the F006 waste is placed in containers, the large quantity generator shall comply with the applicable conditions for exemption under sub. (1) (a). NR 662.017(3)(d)1.b.b. If the F006 is placed in tanks, the large quantity generator shall comply with the applicable conditions for exemption under sub. (1) (b). NR 662.017(3)(d)1.c.c. If the F006 is placed in containment buildings, the large quantity generator shall comply with subch. DD of ch. NR 665, and shall place its professional engineer certification that the building complies with the design standards specified in s. NR 665.1101 in the facility’s files prior to operation of the unit. One of the following records shall be maintained and readily available for inspection: 1) A written description of procedures to ensure that the F006 waste remains in the unit for no more than 180 days, a written description of the waste generation, and management practices for the facility showing that they are consistent with the 180-day limit, and documentation that the large quantity generator is complying with the procedures.
2) Documentation that the unit is emptied at least once every 180 days.
NR 662.017(3)(d)3.3. The date upon which each period of accumulation begins is clearly marked and shall be clearly visible for inspection on each container.
