Current through Register Vol. 24-14, July 15, 2024
Small containers of dangerous waste may be placed in overpacked
				drums (or labpacks) provided that the following conditions are met:
(1) Dangerous waste must be packaged in
			 nonleaking inside containers. The inside containers must be of a design and
			 constructed of a material that will not react dangerously with, be decomposed
			 by, or be ignited by the contained waste. Inside containers must be tightly and
			 securely sealed and, to the extent possible, should be full and have as little
			 air as possible in them to minimize voids. The inside containers must be of the
			 size and type specified in the Department of Transportation (DOT) hazardous
			 materials regulations (49 C.F.R. Parts 173, 178, and 179), if those regulations
			 specify a particular inside container for the waste;
(2) The inside containers must be overpacked
			 in an open head DOT-specification drum shipping container which meets all of
			 the requirements of 49 C.F.R. Parts 173, 178, and 179. The overpack container
			 must not exceed a capacity of 416-liter (110 gallon). The overpack container
			 must have a sufficient quantity of sorbent material to completely sorb all of
			 the liquid contents of the inside containers. The sorbent in overpack
			 containers to be placed in a landfill must be nonbiodegradable in accordance
			 with WAC 173-303-140(4)(b)(iv).
			 The outer container must be full after it has been packed with inside
			 containers and sorbent material;
(3) The sorbent material used must not be
			 capable of reacting dangerously with, being decomposed by, or being ignited by
			 the contents of the inside containers, in accordance with WAC
			 173-303-395(1)(b);
(4) Incompatible wastes, as defined in WAC
			 173-303-040, must not be placed
			 in the same outside container; and
(5) Reactive wastes, other than cyanide- or
			 sulfide-bearing waste as defined in WAC
			 173-303-090(7)(a)(v),
			 must be treated or rendered nonreactive prior to packaging in accordance with
			 subsections (1) through (4) of this section. Cyanide- and sulfide-bearing
			 reactive waste may be packed in accordance with subsections (1) through (4) of
			 this section without first being treated or rendered nonreactive.
(6) An itemized listing of the chemicals,
			 their concentrations and quantities per labpack must be kept by the generator
			 for five years and must be readily available in case of an emergency during
			 shipment, and for the purposes of preparing annual reports under WAC
			 173-303-220.
(7) Such disposal is in compliance with the
			 requirements of WAC
			 173-303-140(2)(a).
			 Persons who incinerate labpacks according to the requirements in
			 40 C.F.R.
			 268.42(c)(1) (incorporated
			 by reference at WAC
			 173-303-140(2)(a))  may use fiber drums in place of metal
			 outer containers. Such fiber drums must meet the DOT specifications in
			 49 C.F.R.
			 173.12 and be overpacked according to the
			 requirements in subsection (2) of this section.
