Wisconsin Administrative Code › Department of Natural Resources › NR 600-699 - Environmental Protection - Hazardous Waste Management › Chapter NR 662 - Hazardous Waste Generator Standards › Subchapter A - General › Section NR 662.017 - Conditions for exemption for a large quantity generator that accumulates hazardous waste

Current through June 24, 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.
