NR 661 NoteNote: Chapter NR 661 as it existed on August 31, 2020, is repealed and a new ch. NR 661 is created by CR 19-082, eff. 9-1-20. NR 661.0001(1)(1) This chapter identifies solid wastes subject to regulation as hazardous wastes under chs. NR 662 to 665, 668, and 670, and subject to the notification requirements under s. NR 660.07. In this chapter: NR 661.0001(1)(a)(a) Subchapter A defines the terms “solid waste” and “hazardous waste,” identifies wastes that are excluded from regulation under chs. NR 662 to 666, 668, and 670, and establishes special management requirements for hazardous waste produced by very small quantity generators and hazardous waste that is recycled. NR 661.0001(1)(b)(b) Subchapter B sets forth the criteria used by the department to identify characteristics of hazardous waste and to list particular hazardous wastes. NR 661.0001(2)(a)(a) The definition of solid waste contained in this chapter applies only to wastes that also are hazardous for the 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 661.0001(2)(b)(b) This chapter identifies only some of the materials that are solid wastes and hazardous wastes for the purposes of ss. 291.15, 291.85, 291.91, and 291.93, Stats., and 42 USC 6927, 6934, and 6973 (a). A material that 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 the purposes of those provisions if any of the following are met: NR 661.0001(2)(b)1.1. In the case of ss. 291.15, 291.91, and 291.93, Stats., or 42 USC 6927 and 6934, the department or EPA has reason to believe that the material may be a solid waste within the meaning of s. 289.01 (33), Stats., and section 1004 (27) of RCRA, or a hazardous waste within the meaning of s. 291.01 (7), Stats., and section 1004 (5) of RCRA.
