Ch. NR 661 Note Note: Chapter NR 661 as it existed on August 31, 2020, is repealed and a new ch.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.

subch. A of ch. NR 661 Subchapter A — General

NR 661.0001 NR 661.0001 Purpose, scope and definitions.

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(1)(c) (c) Subchapter C identifies characteristics of hazardous waste.

NR 661.0001(1)(d) (d) Subchapter D lists particular hazardous wastes.

NR 661.0001(2) (2) 

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.
