NR 664.0312NR 664.0312Special requirements for ignitable or reactive waste.
NR 664.0312(1)(1)Except as provided in sub. (2), and in s. NR 664.0316, ignitable or reactive waste may not be placed in a landfill, unless the waste and landfill meet all applicable requirements of ch. NR 668 and both of the following:
NR 664.0312(1)(a)(a) The resulting waste, mixture or dissolution of material no longer meets the definition of ignitable or reactive waste under s. NR 661.0021 or 661.0023.
NR 664.0312(1)(b)(b) Section NR 664.0017 (2) is complied with.
NR 664.0312(2)(2)Except for prohibited wastes which remain subject to treatment standards in subch. D of ch. NR 668, ignitable wastes in containers may be landfilled without meeting the requirements of sub. (1), provided that the wastes are disposed of in such a way that they are protected from any material or conditions which may cause them to ignite. At a minimum, ignitable wastes shall be disposed of in non-leaking containers which are carefully handled and placed so as to avoid heat, sparks, rupture or any other condition that might cause ignition of the wastes; shall be covered daily with soil or other non-combustible material to minimize the potential for ignition of the wastes and may not be disposed of in cells that contain or will contain other wastes which may generate heat sufficient to cause ignition of the waste.

NR 664.0314NR 664.0314Special requirements for bulk and containerized liquids.
NR 664.0314(1)(1)The placement of bulk or non-containerized liquid hazardous waste or hazardous waste containing free liquids (whether or not sorbents have been added) in any landfill is prohibited.
NR 664.0314(2)(2)To demonstrate the absence or presence of free liquids in either a containerized or a bulk waste, the following test shall be used: Method 9095B (paint filter liquids test) as described in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA SW-846, incorporated by reference in s. NR 660.11.
NR 664.0314(3)(3)Containers holding free liquids may not be placed in a landfill unless par. (a), (b), (c) or (d) applies:
NR 664.0314(3)(a)(a) All free-standing liquid is handled in one of the following ways:
NR 664.0314(3)(a)1.1. It has been removed by decanting, or other methods.
NR 664.0314(3)(a)2.2. It has been mixed with sorbent or solidified so that free-standing liquid is no longer observed.
NR 664.0314(3)(a)3.3. It has been otherwise eliminated.
NR 664.0314(3)(b)(b) The container is very small, such as an ampule.
NR 664.0314(3)(c)(c) The container is designed to hold free liquids for use other than storage, such as a battery or capacitor.
NR 664.0314(3)(d)(d) The container is a lab pack as defined in s. NR 664.0316 and is disposed of in accordance with s. NR 664.0316.
NR 664.0314(4)(4)Sorbents used to treat free liquids to be disposed of in landfills shall be nonbiodegradable. Nonbiodegradable sorbents are materials listed or described in par. (a); materials that pass one of the tests in par. (b) or materials that are determined by EPA to be nonbiodegradable through the 40 CFR part 260 petition process.
NR 664.0314(4)(a)(a) Nonbiodegradable sorbents are any of the following:
NR 664.0314(4)(a)1.1. Inorganic minerals, other inorganic materials and elemental carbon (for example, aluminosilicates, clays, smectites, Fuller’s earth, bentonite, calcium bentonite, montmorillonite, calcined montmorillonite, kaolinite, micas (illite), vermiculites, zeolites; calcium carbonate (organic free limestone); oxides or hydroxides, alumina, lime, silica (sand), diatomaceous earth; perlite (volcanic glass); expanded volcanic rock; volcanic ash; cement kiln dust; fly ash; rice hull ash; activated charcoal or activated carbon).
NR 664.0314(4)(a)2.2. High molecular weight synthetic polymers (for example, polyethylene, high density polyethylene (HDPE), polypropylene, polystyrene, polyurethane, polyacrylate, polynorborene, polyisobutylene, ground synthetic rubber, cross-linked allylstyrene and tertiary butyl copolymers). This does not include polymers derived from biological material or polymers specifically designed to be degradable.
NR 664.0314(4)(a)3.3. Mixtures of these nonbiodegradable materials.
NR 664.0314(4)(b)(b) The sorbent material may be determined to be nonbiodegradable using any of the following tests:
NR 664.0314(4)(b)1.1. ASTM Method G21-70 (1984a)—Standard Practice for Determining Resistance of Synthetic Polymer Materials to Fungi, incorporated by reference in s. NR 660.11.
NR 664.0314(4)(b)2.2. ASTM Method G22-76 (1984b)—Standard Practice for Determining Resistance of Plastics to Bacteria, incorporated by reference in s. NR 660.11.
