(1) Applicability. The regulations in this
			 section apply to owners and operators of all dangerous waste facilities that
			 store dangerous waste in containers.
(2) Condition of containers. If a container
			 holding dangerous waste is not in good condition (e.g., severe corroding or
			 rusting or flaking or scaling, and/or apparent structural defects) or if it
			 begins to leak, the owner or operator must transfer the dangerous waste from
			 the container to a container that is in good condition or manage the waste in
			 some other way that complies with the requirements of chapter 173-303 WAC. In
			 addition, the owner or operator must address leaks and spills in accordance
			 with the applicable provisions of WAC
			 173-303-145
			 and
			 173-303-360.
(3) Identification of containers. The owner
			 or operator storing dangerous waste in containers must do the following:
(a) Clearly label or mark containers with the
			 words "Dangerous Waste" or "Hazardous Waste." Except for containers one gallon
			 (or four liters) and under, the lettering must be legible from a distance of
			 twenty-five feet or the lettering size is a minimum of one-half inch in
			 height.
(b) Clearly label or mark
			 containers with an indication of the hazards of the contents (examples include,
			 but are not limited to, the applicable dangerous waste characteristic(s) and
			 criteria of ignitable, corrosive, reactive and toxic and the applicable
			 hazard(s) identified for listed dangerous wastes). The label or marking must
			 be:
(i) Legible and/or recognizable from a
			 distance of twenty-five feet or the lettering size is a minimum of one-half
			 inch in height; and
(ii) Include
			 descriptive word(s) and/or pictogram(s) that identifies the hazards associated
			 with the contents of the containers for employees, emergency response
			 personnel, waste handlers, and the public; for containers one gallon (or four
			 liters) and under the label, marking or lettering can be appropriate for the
			 size of the container.
(c) Affix labels upon transfer of dangerous
			 wastes from one container to another. The owner or operator must destroy or
			 otherwise remove labels from the emptied container, unless the container will
			 continue to be used for storing dangerous waste at the facility.
(d) Ensure that labels are not obscured,
			 removed, or otherwise unreadable in the course of inspection required under WAC
			 173-303-320.

			 designate an area at a facility as a corrective action management unit for the
			 purpose of treating, storing or disposing of CAMU-eligible waste that
			 originates at the same facility in order to implement remedies under this
			 section or to implement other cleanup actions. Corrective action management
			 unit means an area within a facility that is used only for managing
			 CAMU-eligible wastes for implementing corrective action or cleanup at the
			 facility. A CAMU must be located within the contiguous property under the
			 control of the owner or operator where the wastes to be managed in the CAMU
			 originated. One or more CAMUs may be designated at a facility.
(a) CAMU-eligible waste means:
(i) All solid and dangerous wastes, and all
			 media (including groundwater, surface water, soils, and sediments) and debris,
			 that are managed for implementing cleanup. As-generated wastes (either
			 dangerous or nondangerous) from ongoing industrial operations at a site are not
			 CAMU-eligible wastes.
(ii) Wastes
			 that would otherwise meet the description in (a)(i) of this subsection are not
			 "CAMU-Eligible Wastes" where:
(A) The wastes
			 are dangerous wastes found during cleanup in intact or substantially intact
			 containers, tanks, or other nonland-based units found above ground, unless the
			 wastes are first placed in the tanks, containers or nonland-based units as part
			 of cleanup, or the containers or tanks are excavated during the course of
			 cleanup; or
(B) The department
			 exercises the discretion in (b) of this subsection to prohibit the wastes from
			 management in a CAMU.
(iii) Notwithstanding (a)(i) of this
			 subsection, where appropriate, as-generated nondangerous waste may be placed in
			 a CAMU where such waste is being used to facilitate treatment or the
			 performance of the CAMU.

			 remedies;
(b) Waste management
			 activities associated with the CAMU will not create unacceptable risks to
			 humans or the environment resulting from exposure to dangerous wastes or
			 dangerous constituents;
(c) The
			 CAMU will include uncontaminated areas of the facility only if including such
			 areas for the purposes of managing CAMU-eligible wastes is more protective than
			 management of such wastes at contaminated areas of the facility;
(d) Areas within the CAMU where wastes remain
			 in place after closure of the CAMU, will be managed and contained so as to
			 minimize future releases of dangerous wastes and dangerous constituents to the
			 extent practicable;
