Wisconsin Administrative Code › Department of Natural Resources › NR 600-699 - Environmental Protection - Hazardous Waste Management › Chapter NR 668 - Hazardous Waste Land Disposal Restrictions › Subchapter A - General › Section NR 668.02 - Definitions applicable in this chapter

Current through June 24, 2024
When used in this chapter the following terms have the
					 meanings given below:
(1) "Halogenated
				  organic compounds" or "HOCs" means those compounds having a carbon-halogen bond
				  which are listed under ch. NR 668 Appendix III.
(2) "Hazardous constituent" or "hazardous
				  constituents" means those constituents listed in ch. NR 661 Appendix
				  VIII.
(3) "Land disposal" means
				  placement in or on the land, except in a corrective action management unit or
				  staging pile, and includes, but is not limited to, placement in a landfill,
				  surface impoundment, waste pile, injection well, salt dome formation, salt bed
				  formation, underground mine or cave, or placement in a concrete vault, or
				  bunker intended for disposal purposes.
(4) "Nonwastewaters" means wastes that do not
				  meet the criteria for wastewaters in s. NR 668.02(6).
(5) "Polychlorinated biphenyls" or "PCBs"
				  means halogenated organic compounds defined in accordance with
				  40
				  CFR 761.3.
(6) "Wastewaters" means wastes that contain
				  less than one % by weight total organic carbon (TOC) and less than one% by
				  weight total suspended solids (TSS).
(7) "Debris" means solid material exceeding a
				  60 mm particle size that is intended for disposal and that is a manufactured
				  object; or plant or animal matter; or natural geologic material. However, the
				  following materials are not debris: any material for which a specific treatment
				  standard is provided in subch. D, namely lead acid batteries, cadmium
				  batteries, and radioactive lead solids; process residuals such as smelter slag
				  and residues from the treatment of waste, wastewater, sludges, or air emission
				  residues; and intact containers of hazardous waste that are not ruptured and
				  that retain at least 75% of their original volume. A mixture of debris that has
				  not been treated to the standards provided by s.
				  NR
				  668.45 and other material is regulated as debris if
				  the mixture is comprised primarily of debris, by volume, based on visual
				  inspection.
(8) "Hazardous debris"
				  means debris that contains a hazardous waste listed in subch. D of ch. NR 661,
				  or that exhibits a characteristic of hazardous waste identified in subch. C of
				  ch. NR 661. Any deliberate mixing of prohibited hazardous waste with debris
				  that changes its treatment classification, for example, from waste to hazardous
				  debris, is not allowed under the dilution prohibition in s.
				  NR
				  668.03.
(9) "Underlying hazardous constituent" means
				  any constituent listed in s.
				  NR
				  668.48, Table UTS-Universal Treatment Standards,
				  except fluoride, selenium, sulfides, vanadium, and zinc, which can reasonably
				  be expected to be present at the point of generation of the hazardous waste at
				  a concentration above the constituent-specific UTS treatment
				  standards.
(10) "Inorganic
				  metal-bearing waste" means waste for which EPA has established treatment
				  standards for metal hazardous constituents, and which does not otherwise
				  contain significant organic or cyanide content as described in s.
				  NR
				  668.03(3) (a), and is specifically
				  listed in ch. NR 668 Appendix XI.
(11) "Soil" means unconsolidated earth
				  material composing the superficial geologic strata (material overlying
				  bedrock), consisting of clay, silt, sand, or gravel size particles as
				  classified by the U.S. natural resources conservation service, or a mixture of
				  such materials with liquids, sludges or solids which is inseparable by simple
				  mechanical removal processes and is made up primarily of soil by volume based
				  on visual inspection. Any deliberate mixing of prohibited hazardous waste with
				  soil that changes its treatment classification, for example, from waste to
				  contaminated soil, is not allowed under the dilution prohibition in s.
				  NR
				  668.03.
