Current through Register Vol. 48, No. 6, June 28, 2024
A large quantity generator may accumulate hazardous waste
					 on site without a permit or interim status, and without complying with the
					 requirements of R.61-79.124, 264, and 270, or the notification requirements of
					 the SC Hazardous Waste Management Act Section
					 44-56-120
					 and section 3010 of RCRA, provided that all of the following conditions for
					 exemption are met:
(a) Accumulation. A
				  large quantity generator accumulates hazardous waste on site for no more than
				  ninety (90) days, unless in compliance with the accumulation time limit
				  extension or F006 accumulation conditions for exemption in paragraphs (b)
				  through (e) of this section. The following accumulation conditions also apply:
(1) Accumulation of hazardous waste in
				  containers. If the hazardous waste is placed in containers, the large quantity
				  generator must comply with the following:
(i)
				  Air emission standards. The applicable requirements of subparts AA, BB, and CC
				  of R.61-79.265;
(ii) Condition of
				  containers. If a container holding hazardous waste is not in good condition, or
				  if it begins to leak, the large quantity generator must 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;
(iii) Compatibility of waste with container.
				  The large quantity generator must 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;
(iv)
				  Management of containers.
(A) A container
				  holding hazardous waste must always be closed during accumulation, except when
				  it is necessary to add or remove waste.
(B) A container holding hazardous waste must
				  not be opened, handled, or stored in a manner that may rupture the container or
				  cause it to leak.
(v)
				  Inspections. At least weekly, the large quantity generator must inspect central
				  accumulation areas. The large quantity generator must look for leaking
				  containers and for deterioration of containers caused by corrosion or other
				  factors. See paragraph (a)(1)(ii) of this section for remedial action required
				  if deterioration or leaks are detected.
(vi) Special conditions for accumulation of
				  ignitable and reactive wastes.
(A) Containers
				  holding ignitable or reactive waste must be located at least fifteen (15)
				  meters (50 feet) 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 must be maintained as long as ignitable or
				  reactive hazardous waste is accumulated in this area.
(B) The large quantity generator must take
				  precautions to prevent accidental ignition or reaction of ignitable or reactive
				  waste. This waste must be separated and protected from sources of ignition or
				  reaction including but not limited to the following: Open flames, smoking,
				  cutting and welding, hot surfaces, frictional heat, sparks (static, electrical,
				  or mechanical), spontaneous ignition (e.g., from heat-producing chemical
				  reactions), and radiant heat. While ignitable or reactive waste is being
				  handled, the large quantity generator must confine smoking and open flame to
				  specially designated locations. "No Smoking" signs must be conspicuously placed
				  wherever there is a hazard from ignitable or reactive waste.
(vii) Special conditions for
				  accumulation of incompatible wastes.
(A)
				  Incompatible wastes, or incompatible wastes and materials, (see appendix V of
				  R.61-79.265 for examples) must not be placed in the same container, unless
				  R.61-79.265.17(b) is complied with.
(B) Hazardous waste must not be placed in an
				  unwashed container that previously held an incompatible waste or material (see
				  appendix V of R.61-79.265 for examples), unless 265.17(b) is complied
				  with.
(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 must be separated from the other materials or protected from them
				  by means of a dike, berm, wall, or other device.
