Small containers of hazardous waste in overpacked drums (lab packs) may be placed in a landfill if all of the following requirements are met: NR 664.0316(1)(1) Hazardous waste shall be packaged in non-leaking inside containers. The inside containers shall be of a design and constructed of a material that will not react dangerously with, be decomposed by or be ignited by the contained waste. Inside containers shall be tightly and securely sealed. The inside containers shall be of the size and type specified in the U.S. department of transportation (DOT) hazardous materials regulations (49 CFR parts 173, 178 and 179), if those regulations specify a particular inside container for the waste. NR 664.0316(2)(2) The inside containers shall be overpacked in an open head DOT-specification metal shipping container (49 CFR parts 178 and 179) of no more than 416-liter (110 gallon) capacity and surrounded by, at a minimum, a sufficient quantity of sorbent material, determined to be nonbiodegradable in accordance with s. NR 664.0314 (4), to completely sorb all of the liquid contents of the inside containers. The metal outer container shall be full after it has been packed with inside containers and sorbent material. NR 664.0316(3)(3) The sorbent material used may not be capable of reacting dangerously with, being decomposed by or being ignited by the contents of the inside containers, in accordance with s. NR 664.0017 (2). NR 664.0316(4)(4) Incompatible wastes, as defined in s. NR 660.10, may not be placed in the same outside container. NR 664.0316(5)(5) Reactive wastes, other than cyanide- or sulfide-bearing waste as defined in s. NR 661.0023 (1) (e), shall be treated or rendered non-reactive prior to packaging in accordance with subs. (1) to (4). Cyanide- and sulfide-bearing reactive waste may be packed in accordance with subs. (1) to (4) without first being treated or rendered non-reactive. NR 664.0316(6)(6) The disposal is in compliance with the requirements of ch. NR 668. Persons who incinerate lab packs according to the requirements in s. NR 668.42 (3) (a) may use fiber drums in place of metal outer containers. The fiber drums shall meet the DOT specifications in 49 CFR 173.12 and be overpacked according to the requirements in sub.

NR 664.0317(1)(1) Hazardous wastes F020, F021, F022, F023, F026 and F027 may not be placed in a landfill unless the owner or operator operates the landfill in accord with a management plan for these wastes that is approved by the department pursuant to the standards set out in this subsection, and in accord with all other applicable requirements of this chapter. All of the following factors shall be considered: NR 664.0317(1)(a)(a) The volume and physical and chemical characteristics of the wastes, including their potential to migrate through the soil or to volatilize or escape into the atmosphere. NR 664.0317(1)(b)(b) The attenuative properties of underlying and surrounding soils or other materials. NR 664.0317(1)(c)(c) The mobilizing properties of other materials co-disposed with these wastes. NR 664.0317(1)(d)(d) The effectiveness of additional treatment, design or monitoring requirements. NR 664.0317(2)(2) The department may determine that additional design, operating and monitoring requirements are necessary for landfills managing hazardous wastes F020, F021, F022, F023, F026 and F027 in order to reduce the possibility of migration of these wastes to groundwater, surface water or air so as to protect human health and the environment. NR 664.0317 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06. NR 664.0340(1)(1) This subchapter applies to owners and operators of hazardous waste incinerators (as defined in s. NR 660.10), except as s. NR 664.0001 provides otherwise. NR 664.0340(2)(a)(a) Except as provided by pars. (b) to (d), the standards of this subchapter do not apply to a new hazardous waste incineration unit that becomes subject to hazardous waste license requirements after October 12, 2005, and no longer apply when an owner or operator of an existing hazardous waste incineration unit demonstrates compliance with the maximum achievable control technology (MACT) requirements of 40 CFR part 63, subpart EEE, by conducting a comprehensive performance test and submitting proof of a postmarked notification of compliance to the department under 40 CFR 63.1207 (j) and 63.1210 (d) documenting compliance with 40 CFR part 63, subpart EEE. Nevertheless, even after this demonstration of compliance with the MACT standards, hazardous waste license conditions that were based on the standards of this chapter will continue to be in effect until the department removes them from the license or denies, suspends or revokes the license, unless the license expressly provides otherwise. NR 664.0340(2)(d)(d) All of the following requirements remain in effect for startup, shutdown and malfunction events if the owner or operator elects to comply with s. NR 670.235 (1) (a) 1. to minimize emissions of toxic compounds from these events: NR 664.0340(2)(d)2.2. Section NR 664.0345 (3) requiring compliance with the emission standards and operating requirements during startup and shutdown if hazardous waste is in the combustion chamber, except for particular hazardous wastes. NR 664.0340(3)(3) After consideration of the waste analysis included with the feasibility and plan of operation report, the department, in establishing the license conditions, shall exempt the applicant from this subchapter except ss. NR 664.0341 and 664.0351, if all of the following conditions are met: NR 664.0340(3)(a)(a) The department finds that the waste to be burned is one of the following: NR 664.0340(3)(a)2.2. Listed as a hazardous waste in subch. D of ch. NR 661 solely because it is reactive (hazard code R) for characteristics other than those in s. NR 661.0023 (1) (d) and (e), and will not be burned when other hazardous wastes are present in the combustion zone. NR 664.0340(3)(a)3.3. A hazardous waste solely because it possesses the characteristic of ignitability, corrosivity or both, as determined by the test for characteristics of hazardous wastes under subch. C of ch. NR 661. NR 664.0340(3)(b)(b) The waste analysis shows that the waste contains none of the hazardous constituents in ch. NR 661 Appendix VIII, which would reasonably be expected to be in the waste. NR 664.0340(4)(4) If the waste to be burned is one which is described by sub. (3) (a) 1., 2., 3. or 4. and contains insignificant concentrations of the hazardous constituents in ch. NR 661 Appendix VIII, then the department may, in establishing license conditions, exempt the applicant from all requirements of this subchapter, except ss. NR 664.0341 and 664.0351, after consideration of the waste analysis included with the feasibility and plan of operation report, unless the department finds that the waste will pose a threat to human health and the environment when burned in an incinerator.
