Universal Citation: WI Admin Code § NR 662.017

Current through August 26, 2024

A large quantity generator may accumulate hazardous waste on-site without a license or interim status, and without complying with the requirements of chs. NR 664 to 667 and 670, or from any requirement for notification under s. NR 660.07, provided that all of the following conditions for exemption are met:

(1) ACCUMULATION. A large quantity generator accumulates hazardous waste on-site for no more than 90 days, unless in compliance with the accumulation time limit extension or accumulation conditions for exemption in subs. (2) to (5). All of the following accumulation conditions also apply:

(a) Accumulation of hazardous waste in containers. If the hazardous waste is placed in containers, the large quantity generator shall comply with the following:

1. 'Air emission standards.' The applicable requirements of subchs. AA, BB, and CC of ch. NR 665.

2. '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 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.

3. '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.

4. 'Management of containers.'

a. A container holding hazardous waste shall always be closed during accumulation, except when it is necessary to add or remove waste.

b. A container holding hazardous waste may not be opened, handled, or stored in a manner that may rupture the container or cause it to leak.

5. 'Inspections.' At least weekly, the large quantity generator shall inspect central accumulation areas. The large quantity generator shall look for leaking containers and for deterioration of containers caused by corrosion or other factors. See subd. 2. for remedial action required if deterioration or leaks are detected.

6. 'Special conditions for accumulation of ignitable and reactive wastes.'

a. A container holding ignitable or reactive waste shall be located at least 15 meters from the facility's property line unless a written approval is obtained from the authority having jurisdiction over the local fire code allowing hazardous waste accumulation to occur within this restricted area. A record of the written approval shall be maintained as long as ignitable or reactive hazardous waste is accumulated in this area.

b. The large quantity generator shall take precautions to prevent accidental ignition or reaction of ignitable or reactive waste. This waste shall be separated and protected from sources of ignition or reaction including the following: open flames, smoking, cutting, welding, hot surfaces, frictional heat, static sparks, electrical sparks, mechanical sparks, spontaneous ignition, and radiant heat. While ignitable or reactive waste is being handled, the large quantity generator shall confine smoking and open flame to specially designated locations. "No Smoking" signs shall be conspicuously placed wherever there is a hazard from ignitable or reactive waste.

7. 'Special conditions for accumulation of incompatible wastes.'

a. The generator may not place incompatible wastes, or incompatible wastes and materials, in the same container unless the generator complies with the requirements specified in s. NR 665.0017(2).

b. The generator may not place hazardous waste in an unwashed container that previously held an incompatible waste or material unless the generator complies with the requirements specified in s. NR 665.0017(2).

c. A container holding a hazardous waste that is incompatible with any waste or other materials accumulated or stored nearby in other containers, piles, open tanks, or surface impoundments shall be separated from the other materials or protected from them by means of a dike, berm, wall, or other device.

(b) Accumulation of hazardous waste in tanks. If the waste is placed in tanks, the large quantity generator shall comply with the applicable requirements of subch. J of ch. NR 665, except s. NR 665.0197(3) for closure and post-closure care, and s. NR 665.0200 as well as the applicable requirements of subchs. AA, BB, and CC of ch. NR 665.

1. Subchapter W of ch. NR 665.

2. The large quantity generator shall remove all wastes from the drip pad at least once every 90 days. Any hazardous wastes that are removed from the drip pad are subject to the 90 day accumulation limit specified in sub. (1) and s. NR 662.015, if the hazardous wastes are being managed in satellite accumulation areas prior to being moved to a central accumulation area.

3. The large quantity generator shall maintain on-site at the facility and readily available for inspection all of the following records:

a. A written description of procedures that are followed to ensure that all wastes are removed from the drip pad and associated collection system at least once every 90 days.

b. Documentation of each waste removal, including the quantity of waste removed from the drip pad and the sump or collection system and the date and time of removal.

(d) Accumulation of hazardous waste in containment buildings.If the waste is placed in containment buildings, the large quantity generator shall comply with subch. DD of ch. NR 665. The generator shall label its containment building with the words "Hazardous Waste" in a conspicuous place easily visible to employees, visitors, emergency responders, waste handlers, or other persons on-site, and also in a conspicuous place provide an indication of the hazards of the contents.

(6) CONSOLIDATION OF HAZARDOUS WASTE RECEIVED FROM VERY SMALL QUANTITY GENERATORS. In this subsection "control" means the power to direct the policies of the generator, whether by the ownership of stock, voting rights, or otherwise, except that a contractor who operates generator facilities on behalf of a different person may not be deemed to "control" such generators. Large quantity generators may accumulate on-site hazardous waste received from very small quantity generators under control of the same person as defined in s. NR 660.10(90), without a storage license or interim status and without complying with the requirements under chs. NR 664 to 668 and 670, and the notification requirements under s. NR 660.07, provided they comply with all of the following:

2. Submit an updated Site ID form using EPA Form 8700-12 within 30 days after a change in the name or site address for the very small quantity generator.

(b) The large quantity generator maintains records of shipments for 3 years from the date the hazardous waste was received from the very small quantity generator. These records shall identify the name, site address, and contact information for the very small quantity generator and include a description of the hazardous waste received, including the quantity and the date the waste was received.

(c) The large quantity generator complies with the independent requirements identified in s. NR 662.010(1) (a) 3. and the conditions for exemption in this section for all hazardous waste received from a very small quantity generator. For purposes of the labeling and marking regulations under sub. (1)

(e), the large quantity generator shall label the container or unit with the date the hazardous waste was received from the very small quantity generator. If the large quantity generator is consolidating incoming hazardous waste from a very small quantity generator with either its own hazardous waste or with hazardous waste from other very small quantity generators, the large quantity generator shall label each container or unit with the earliest date any hazardous waste in the container was accumulated on-site.

(7) REJECTED LOAD. A large quantity generator who 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 under s. NR 664.0072 or 665.0072 may accumulate the returned waste on-site in accordance with subs. (1) and (2). Upon receipt of the returned shipment, the generator shall do one of the following:
