subd. 2. or
sub. (7) or
(8), any solid waste generated from the treatment, storage or disposal of a hazardous waste, including any sludge, spill residue, ash, emission control dust or leachate (but not including precipitation run-off) is a hazardous waste. (However, materials that are reclaimed from solid wastes and that are used beneficially are not solid wastes and hence are not hazardous wastes under this subdivision unless the reclaimed material is burned for energy recovery or used in a manner constituting disposal.)
NR 661.03(3)(b)2.
2. All of the following solid wastes are not hazardous even though they are generated from the treatment, storage or disposal of a hazardous waste, unless they exhibit one or more of the characteristics of hazardous waste:
NR 661.03(3)(b)2.a.
a. Waste pickle liquor sludge generated by lime stabilization of spent pickle liquor from the iron and steel industry (standard industrial classification (SIC) codes 331 and 332).

c. 1) Nonwastewater residues, such as slag, resulting from high temperature metals recovery (HTMR) processing of K061, K062 or F006 waste, in units identified as rotary kilns, flame reactors, electric furnaces, plasma arc furnaces, slag reactors, rotary hearth furnace or electric furnace combinations or industrial furnaces (as defined in the definition for industrial furnace in
s. NR 660.10 (60) (f),
(g) and
(m)), that are disposed in approved solid waste disposal facilities, if these residues meet the generic exclusion levels identified in the following tables for all constituents, and exhibit no characteristics of hazardous waste. Testing requirements shall be incorporated in a facility's waste analysis plan or a generator's self-implementing waste analysis plan; at a minimum, composite samples of residues shall be collected and analyzed quarterly or when the process or operation generating the waste changes. Persons claiming this exclusion in an enforcement action will have the burden of proving by clear and convincing evidence that the material meets all of the exclusion requirements.

3. Except as provided in
subd. 4., the spent material is stored in tanks, containers or buildings meeting the following minimum integrity standards: a building shall be an engineered structure with a floor, walls and a roof all of which are made of non-earthen materials providing structural support (except smelter buildings may have partially earthen floors provided the spent material is stored on the non-earthen portion), and have a roof suitable for diverting rainwater away from the foundation; a tank shall be free standing, not be a surface impoundment (as defined in
s. NR 660.10), and be manufactured of a material suitable for containment of its contents; a container shall be free standing and be manufactured of a material suitable for containment of its contents. If tanks or containers contain any particulate which may be subject to wind dispersal, the owner or operator shall operate these units in a manner which controls fugitive dust. Tanks, containers and buildings shall be designed, constructed and operated to prevent significant releases to the environment of these materials.
NR 661.04(1)(q)4.
4. The department may make a site-specific determination, after public review and comment, that only solid mineral processing spent material may be placed on pads, rather than in tanks, containers or buildings. Solid mineral processing spent materials do not contain any free liquid. The department shall affirm that pads are designed, constructed and operated to prevent significant releases of the spent material into the environment. Pads shall provide the same degree of containment as tanks, containers and buildings that meet the design, construction and operating requirements in
subd. 3.
NR 661.04(1)(q)4.a.
a. The department shall also consider if storage on pads poses the potential for significant releases via groundwater, surface water and air exposure pathways. Factors to be considered for assessing the groundwater, surface water and air exposure pathways are: the volume and physical and chemical properties of the spent material, including its potential for migration off the pad; the potential for human or environmental exposure to hazardous constituents migrating from the pad via each exposure pathway, and the possibility and extent of harm to human and environmental receptors via each exposure pathway.
NR 661.04(1)(q)4.b.
b. Pads shall meet the following minimum standards: be designed of non-earthen material that is compatible with the chemical nature of the mineral processing spent material, capable of withstanding physical stresses associated with placement and removal, have run on and runoff controls, be operated in a manner which controls fugitive dust and have integrity assurance through inspections and maintenance programs.
NR 661.04(1)(q)4.c.

5. The owner or operator provides notice to the department providing the following information: the types of materials to be recycled, the type and location of the storage units and recycling processes and the annual quantities expected to be placed in land-based units. This notification shall be updated when there is a change in the type of materials recycled or the location of the recycling process.
NR 661.04(1)(q)6.
6. For purposes of
sub. (2) (g), mineral processing spent materials shall be the result of mineral processing and may not include any listed hazardous wastes. Listed hazardous wastes and characteristic hazardous wastes generated by non-mineral processing industries are not eligible for this conditional exclusion from the definition of solid waste.
