NR 661.01(2)(a)(a) The definition of solid waste contained in this chapter applies only to wastes that also are hazardous for purposes of
chs. NR 660 to
673. For example, it does not apply to materials (such as non-hazardous scrap, paper, textiles or rubber) that are not otherwise hazardous wastes and that are recycled.
NR 661.01(2)(b)
(b) This chapter identifies only some of the materials which are solid wastes and hazardous wastes under ss.
291.15,
291.85,
291.91, and
291.93, Stats. A material which is not defined as a solid waste in this chapter, or is not a hazardous waste identified or listed in this chapter, is still a solid waste and a hazardous waste for purposes of these sections if any of the following are met:
NR 661.01(3)(a)
(a) A "spent material" is any material that has been used and as a result of contamination can no longer serve the purpose for which it was produced without processing.
NR 661.01(3)(c)
(c) A "by-product" is a material that is not one of the primary products of a production process and is not solely or separately produced by the production process. Examples are process residues such as slags or distillation column bottoms. The term does not include a co-product that is produced for the general public's use and is ordinarily used in the form it is produced by the process.
NR 661.01(3)(d)
(d) A material is "reclaimed" if it is processed to recover a usable product, or if it is regenerated. Examples are recovery of lead values from spent batteries and regeneration of spent solvents.
NR 661.01(3)(e)
(e) A material is "used or reused" if it is one of the following:
NR 661.01(3)(e)1.
1. Employed as an ingredient (including use as an intermediate) in an industrial process to make a product (for example, distillation bottoms from one process used as feedstock in another process). However, a material will not satisfy this condition if distinct components of the material are recovered as separate end products (as when metals are recovered from metal-containing secondary materials).
NR 661.01(3)(e)2.
2. Employed in a particular function or application as an effective substitute for a commercial product (for example, spent pickle liquor used as phosphorous precipitant and sludge conditioner in wastewater treatment).
NR 661.01(3)(f)
(f) "Scrap metal" is bits and pieces of metal parts (e.g., bars, turnings, rods, sheets, wire) or metal pieces that may be combined together with bolts or soldering (e.g., radiators, scrap automobiles, railroad box cars), which when worn or superfluous can be recycled.
NR 661.01(3)(g)
(g) A material is "recycled" if it is used, reused or reclaimed.
NR 661.01(3)(h)
(h) A material is "accumulated speculatively" if it is accumulated before being recycled. A material is not accumulated speculatively, however, if the person accumulating it can show that the material is potentially recyclable and has a feasible means of being recycled; and that during the calendar year (commencing on January 1) the amount of material that is recycled, or transferred to a different site for recycling, equals at least 75% by weight or volume of the amount of that material accumulated at the beginning of the period. In calculating the percentage of turnover, the 75% requirement is to be applied to each material of the same type (e.g., slags from a single smelting process) that is recycled in the same way (i.e., from which the same material is recovered or that is used in the same way). Materials accumulating in units that would be exempt from regulation under
s. NR 661.04 (3) are not to be included in making the calculation. (Materials that are already defined as solid wastes also are not to be included in making the calculation.) Materials are no longer in this category once they are removed from accumulation for recycling, however.
NR 661.01(3)(i)
(i) "Excluded scrap metal" is processed scrap metal, unprocessed home scrap metal and unprocessed prompt scrap metal.
NR 661.01(3)(j)
(j) "Processed scrap metal" is scrap metal which has been manually or physically altered to either separate it into distinct materials to enhance economic value or to improve the handling of materials. Processed scrap metal includes, but is not limited to scrap metal which has been baled, shredded, sheared, chopped, crushed, flattened, cut, melted or separated by metal type (i.e., sorted), and, fines, drosses and related materials which have been agglomerated. (Shredded circuit boards being sent for recycling are not processed scrap metal. They are covered under the exclusion from the definition of solid waste for shredded circuit boards being recycled
(s. NR 661.04 (1) (n)).
NR 661.01(3)(k)
(k) "Home scrap metal" is scrap metal as generated by steel mills, foundries and refineries such as turnings, cuttings, punchings and borings.
NR 661.01(3)(L)
(L) "Prompt scrap metal" is scrap metal as generated by the metal working or fabrication industries and includes scrap metal such as turnings, cuttings, punchings and borings. Prompt scrap is also known as industrial or new scrap metal.

Definition of hazardous waste. NR 661.03(1)
(1) A solid waste, as defined in
s. NR 661.02, is a hazardous waste if all of the following apply:
NR 661.03(1)(b)1.
1. It exhibits any of the characteristics of hazardous waste identified in subch.
C. However, any mixture of a waste from the extraction, beneficiation and processing of ores and minerals excluded under
s. NR 661.04 (2) (g) and any other solid waste exhibiting a characteristic of hazardous waste under subch.
C is a hazardous waste only if it exhibits a characteristic that would not have been exhibited by the excluded waste alone if the mixture had not occurred, or if it continues to exhibit any of the characteristics exhibited by the non-excluded wastes prior to mixture. Further, for the purposes of applying the toxicity characteristic to these mixtures, the mixture is also a hazardous waste if it exceeds the maximum concentration for any contaminant listed in table 2 that would not have been exceeded by the excluded waste alone if the mixture had not occurred or if it continues to exceed the maximum concentration for any contaminant exceeded by the nonexempt waste prior to mixture.
NR 661.03(1)(b)4.
4. It is a mixture of solid waste and one or more hazardous wastes listed in subch.
D and has not been excluded from this paragraph under
ss. NR 660.20 and
660.22, or
sub. (7) or
(8); however, the following mixtures of solid wastes and hazardous wastes listed in subch.
D are not hazardous wastes (except by application of
subd. 1. or
2.) if the generator can demonstrate that the mixture consists of wastewater the discharge of which is subject to regulation under s.
283.21 (2),
283.31 or
283.33, Stats., (including wastewater at facilities which have eliminated the discharge of wastewater) and one of the following:
NR 661.03(1)(b)4.a.
a. One or more of the following solvents listed in
s. NR 661.31: carbon tetrachloride, tetrachloroethylene, trichloroethylene; if the maximum total weekly usage of these solvents (other than the amounts that can be demonstrated not to be discharged to wastewater) divided by the average weekly flow of wastewater into the headworks of the facility's wastewater treatment or pretreatment system does not exceed one part per million.
NR 661.03(1)(b)4.b.
b. One or more of the following spent solvents listed in
s. NR 661.31: methylene chloride, 1,1,1-trichloroethane, chlorobenzene, o-dichlorobenzene, cresols, cresylic acid, nitrobenzene, toluene, methyl ethyl ketone, carbon disulfide, isobutanol, pyridine, spent chlorofluorocarbon solvents; if the maximum total weekly usage of these solvents (other than the amounts that can be demonstrated not to be discharged to wastewater) divided by the average weekly flow of wastewater into the headworks of the facility's wastewater treatment or pretreatment system does not exceed 25 parts per million.
NR 661.03(1)(b)4.c.
c. One of the following wastes listed in
s. NR 661.32, if the wastes are discharged to the refinery oil recovery sewer before primary oil, water or solids separation: heat exchanger bundle cleaning sludge from the petroleum refining industry (EPA hazardous waste number K050), crude oil storage tank sediment from petroleum refining operations (EPA hazardous waste number K169), clarified slurry oil tank sediment or in-line filter or separation solids from petroleum refining operations (EPA hazardous waste number K170), spent hydrotreating catalyst (EPA hazardous waste number K171) and spent hydrorefining catalyst (EPA hazardous waste number K172).
NR 661.03(1)(b)4.d.
d. A discarded commercial chemical product, or chemical intermediate listed in
s. NR 661.33, arising from de minimis losses of these materials from manufacturing operations in which these materials are used as raw materials or are produced in the manufacturing process. For purposes of this subdivision, de minimis losses include those from normal material handling operations (e.g., spills from the unloading or transfer of materials from bins or other containers, leaks from pipes, valves or other devices used to transfer materials); minor leaks of process equipment, storage tanks or containers; leaks from well maintained pump packings and seals; sample purgings; relief device discharges; discharges from safety showers and rinsing and cleaning of personal safety equipment; and rinsate from empty containers or from containers that are rendered empty by that rinsing.
NR 661.03(1)(b)4.e.
e. Wastewater resulting from laboratory operations containing toxic (T) wastes listed in subch.
D if the annualized average flow of laboratory wastewater does not exceed one percent of total wastewater flow into the headworks of the facility's wastewater treatment or pre-treatment system, or if the waste's combined annualized average concentration does not exceed one part per million in the headworks of the facility's wastewater treatment or pre-treatment facility. Toxic (T) wastes used in laboratories that are demonstrated not to be discharged to wastewater are not to be included in this calculation.
NR 661.03(1)(b)4.f.
f. One or more of the following wastes listed in
s. NR 661.32: wastewaters from the production of carbamates and carbamoyl oximes (EPA hazardous waste number K157), if the maximum weekly usage of formaldehyde, methyl chloride, methylene chloride and triethylamine (including all amounts that can not be demonstrated to be reacted in the process, destroyed through treatment, or is recovered, i.e., what is discharged or volatilized) divided by the average weekly flow of process wastewater prior to any dilutions into the headworks of the facility's wastewater treatment system does not exceed a total of 5 parts per million by weight.
NR 661.03(1)(b)4.g.
g. Wastewaters derived from the treatment of one or more of the following wastes listed in
s. NR 661.32: organic waste (including heavy ends, still bottoms, light ends, spent solvents, filtrates and decantates) from the production of carbamates and carbamoyl oximes (EPA hazardous waste number K156), if the maximum concentration of formaldehyde, methyl chloride, methylene chloride and triethylamine prior to any dilutions into the headworks of the facility's wastewater treatment system does not exceed a total of 5 milligrams per liter.
NR 661.03(1)(b)5.
5. Used oil containing more than 1000 ppm total halogens is presumed to be a hazardous waste because it has been mixed with halogenated hazardous waste listed in subch.
D. Persons may rebut this presumption by demonstrating that the used oil does not contain hazardous waste (for example, by using an analytical method from EPA SW-846, incorporated by reference in
s. NR 660.11, to show that the used oil does not contain significant concentrations of halogenated hazardous constituents listed in
ch. NR 661 Appendix VIII).
NR 661.03(1)(b)5.a.
a. The rebuttable presumption does not apply to metalworking oils or fluids containing chlorinated paraffins, if they are processed, through a tolling agreement, to reclaim metalworking oils or fluids. The presumption does apply to metalworking oils or fluids if the oils or fluids are recycled in any other manner, or disposed.
NR 661.03(1)(b)5.b.
b. The rebuttable presumption does not apply to used oils contaminated with chlorofluorocarbons (CFCs) removed from refrigeration units where the CFCs are destined for reclamation. The rebuttable presumption does apply to used oils contaminated with CFCs that have been mixed with used oil from sources other than refrigeration units.
NR 661.03(2)
(2) A solid waste which is not excluded from regulation under
sub. (1) (a) becomes a hazardous waste when any of the following events occur:
NR 661.03(2)(a)
(a) In the case of a waste listed in subch.
D, when the waste first meets the listing description set forth in subch.
D.
