NR 662.001 HistoryHistory: CR 19-082: cr. Register August 2020 No. 776, eff. 9-1-20. NR 662.010NR 662.010 Purpose, scope, and applicability. NR 662.010(1)(1) The regulations in this chapter establish the following standards for generators of hazardous waste: NR 662.010(1)(a)(a) A person who generates a hazardous waste as defined under ch. NR 661 is subject to all of the following applicable independent requirements in the subchapters and sections: NR 662.010(1)(a)2.d.d. Subchapter B—Manifest requirements applicable to small and large quantity generators. NR 662.010(1)(a)2.e.e. Subchapter C—Pre-transport requirements applicable to small and large quantity generators. NR 662.010(1)(a)3.d.d. Subchapter B—Manifest requirements applicable to small and large quantity generators. NR 662.010(1)(a)3.e.e. Subchapter C—Pre-transport requirements applicable to small and large quantity generators. NR 662.010(1)(b)(b) A generator that accumulates hazardous waste on-site is a person that stores hazardous waste. Such generator is subject to the applicable requirements of chs. NR 664 to 667 and 670, and s. NR 660.07, unless it is any of the following: NR 662.010(1)(c)(c) A generator may not transport, offer its hazardous waste for transport, or otherwise cause its hazardous waste to be sent to a facility that is not a designated facility, as defined in s. NR 660.10 (21), or not otherwise authorized to receive the generator’s hazardous waste. NR 662.010(2)(2) When determining a generator category, a generator shall use s. NR 662.013 to determine which provisions of this chapter are applicable to the generator based on the quantity of hazardous waste generated per calendar month. NR 662.010(5)(5) Any person who imports hazardous waste into the United States shall comply with the standards applicable to generators established in this chapter. NR 662.010(6)(6) A farmer who generates waste pesticides that are hazardous waste and who complies with all of the requirements under s. NR 662.070 is not required to comply with other standards in this chapter or ch. NR 670, 664, 665, 667, or 668 with respect to such pesticides. NR 662.010(7)(7) A person who generates a hazardous waste as defined under ch. NR 661 is subject to all of the following: NR 662.010(7)(a)(a) A generator’s violation of an independent requirement is subject to penalty and injunctive relief under ch. 291, Stats., and 42 USC 6928. NR 662.010(7)(b)(b) A generator’s noncompliance with a condition for exemption in this chapter is not subject to penalty or injunctive relief under ch. 291, Stats., or 42 USC 6928 as a violation of a ch. NR 662 condition for exemption. Noncompliance by any generator with an applicable condition for exemption from storage license and operations requirements means that the facility is a storage facility operating without an exemption from the license, interim status, and operations requirements under chs. NR 664 to 667 and 670, and the notification requirements under s. NR 660.07. Without an exemption, any violations of such storage requirements are subject to penalty and injunctive relief under ch. 291, Stats., or 42 USC 6928. NR 662.010(8)(8) An owner or operator who initiates a shipment of hazardous waste from a treatment, storage, or disposal facility shall comply with the generator standards established in this chapter. NR 662.010(12)(12) In this subsection, “eligible academic entity” has the meaning given in s. NR 662.200 (3) and “laboratory” has the meaning given in s. NR 662.200 (5). A laboratory owned by an eligible academic entity that chooses to be subject to the requirements of subch. K is not subject to any of the following: NR 662.010(12)(a)(a) The independent requirements under s. NR 662.011 or the regulations specified in s. NR 662.015 for large quantity generators and small quantity generators, except as provided in subch. K. NR 662.010 NoteNote: The provisions specified in s. NR 662.015 are applicable to the on-site accumulation of hazardous waste by generators. Therefore, the provisions specified in s. NR 662.015 only apply to owners or operators who are shipping hazardous waste generated at that facility. NR 662.010 NoteNote: A generator that treats, stores, or disposes of hazardous waste on-site is required to comply with the applicable standards and license requirements under chs. NR 664, 665, 666, 668, and 670. NR 662.010(14)(14) Each healthcare facility as defined in s. NR 666.500 shall determine whether it is subject to subch. P of ch. NR 666 for the management of hazardous waste pharmaceuticals, based on the total hazardous waste it generates per calendar month, including both hazardous waste pharmaceuticals and non-pharmaceutical hazardous waste. A healthcare facility that generates more than 100 kg of hazardous waste per calendar month, or more than 1 kg of acute hazardous waste per calendar month, or more than 100 kg per calendar month of any residue or contaminated soil, water, or other debris, resulting from the clean-up of a spill, into or on any land or water, of any acute hazardous wastes listed in s. NR 661.0031 or 661.0033 (5), is subject to subch. P of ch. NR 666 for the management of hazardous waste pharmaceuticals in lieu of this chapter. A healthcare facility that is a very small quantity generator when counting all of its hazardous waste, including both its hazardous waste pharmaceuticals and its non-pharmaceutical hazardous waste, remains subject to s. NR 662.014 and is not subject to subch. P of ch. NR 666, except for ss. NR 666.505 and 666.507 and the optional provisions under s. NR 666.504. NR 662.010 HistoryHistory: CR 19-082: cr. Register August 2020 No. 776, eff. 9-1-20; correction in (1) (a) 2. d., e., h., 3. d. to g., (4), (9), (14) made under s. 35.17, Stats., Register August 2020 No. 776. NR 662.011NR 662.011 Hazardous waste determination and recordkeeping. A person who generates a solid waste, as defined in s. NR 661.0002, shall make an accurate determination as to whether that waste is a hazardous waste in order to ensure wastes are properly managed according to chs. NR 660 to 679. A hazardous waste determination is made using all of the following steps: NR 662.011(1)(1) The hazardous waste determination for each solid waste shall be made at the point of waste generation, before any dilution, mixing, or other alteration of the waste occurs, and at any time in the course of its management that it has, or may have, changed its properties as a result of exposure to the environment or other factors that may change the properties of the waste such that the RCRA classification of the waste may change. NR 662.011(3)(3) If the waste is not excluded under s. NR 661.0004, the person shall use knowledge of the waste to determine whether the waste meets any of the listing descriptions under subch. D of ch. NR 661. Acceptable knowledge that may be used in making an accurate determination as to whether the waste is listed may include waste origin, composition, the process producing the waste, feedstock, and other reliable and relevant information. If the waste is listed, the person may file a delisting petition under 40 CFR 260.20 and 260.22 to demonstrate to the EPA administrator that the waste from this particular site or operation is not a hazardous waste. The department shall recognize an EPA granted delisting unless the department clearly establishes that a delisting would threaten human health or the environment. NR 662.011(4)(4) The person shall also determine whether the waste exhibits one or more hazardous characteristics as identified in subch. C of ch. NR 661 by following all of the following procedures: NR 662.011(4)(a)(a) The person shall apply knowledge of the hazard characteristic of the waste in light of the materials or the processes used to generate the waste. Acceptable knowledge may include any of the following: process knowledge, which describes information about chemical feedstocks and other inputs to the production process; knowledge of products, by-products, and intermediates produced by the manufacturing process; chemical or physical characterization of wastes; information on the chemical and physical properties of the chemicals used or produced by the process or otherwise contained in the waste; testing that illustrates the properties of the waste; or other reliable and relevant information about the properties of the waste or its constituents. A test other than a test method set forth in subch. C of ch. NR 661, or an equivalent test method approved by the department under s. NR 660.21, may be used as evidence of a person’s knowledge to determine whether a solid waste exhibits a characteristic of hazardous waste. However, such tests do not, by themselves, provide definitive results. A person testing the waste shall obtain a representative sample of the waste for the testing, as defined in s. NR 660.10 (101). NR 662.011(4)(b)(b) When available knowledge is inadequate to make an accurate determination, the person shall test the solid waste according to the applicable methods set forth in subch. C of ch. NR 661 or according to an equivalent method approved by the department under s. NR 660.21 and in accordance with all of the following: NR 662.011(4)(b)2.2. When a test method is specified in subch. C of ch. NR 661, the results of the regulatory test, when properly performed, are definitive for determining the regulatory status of the waste. NR 662.011 NoteNote: Wisconsin hazardous waste treatment, storage and disposal facility standard s. NR 664.0013 (1) (a) 1. requires that chemical and physical samples are analyzed by a laboratory certified or registered under ch. NR 149, except for field analyses for pH, specific conductance, and temperature. NR 662.011(5)(5) If the waste is determined to be hazardous, the generator shall refer to chs. NR 661, 664 to 668, and 673 for other possible exclusions or restrictions pertaining to management of the specific waste. NR 662.011(6)(6) A small or large quantity generator shall maintain records supporting its hazardous waste determinations, including records that identify whether a solid waste is a hazardous waste, as defined in s. NR 661.0003. Records shall be maintained for at least 3 years from the date that the waste was last sent to on-site or off-site treatment, storage, or disposal. These records shall comprise the generator’s knowledge of the waste and support the generator’s determination, as described in pars. (3) and (4). The records shall include the following types of information: the results of any tests, sampling, waste analyses, or other determinations made in accordance with this section; records documenting the tests, sampling, and analytical methods used to demonstrate the validity and relevance of such tests; records consulted in order to determine the process by which the waste was generated, the composition of the waste, and the properties of the waste; and records which explain the knowledge basis for the generator’s determination, as described in sub. (4) (a). The periods of record retention referred in this section are extended automatically during the course of any unresolved enforcement action regarding the regulated activity or as requested by the department. NR 662.011(7)(7) If the waste is determined to be hazardous, small quantity generators and large quantity generators shall identify all applicable EPA hazardous waste numbers (EPA hazardous waste codes) in subchs. C and D of ch. NR 661. Prior to shipping the waste off-site, the generator also shall mark its containers with all applicable EPA hazardous waste numbers, or EPA hazardous waste codes, as specified in s. NR 662.032. NR 662.011 HistoryHistory: CR 19-082: cr. Register August 2020 No. 776, eff. 9-1-20; correction in (4) (intro.), (b) 1., (5) made under s. 35.17, Stats., Register August 2020 No. 776. NR 662.013NR 662.013 Generator category determination. A generator shall determine its generator category. A generator’s category is based on the amount of hazardous waste generated each month and may change from month to month. This section sets forth procedures to determine whether a generator is a “very small quantity generator,” a “small quantity generator,” or a “large quantity generator” for a particular month, as each of those terms is defined in s. NR 660.10, by applying any of the following, as applicable: NR 662.013(1)(1) Generators of either acute hazardous waste or non-acute hazardous waste. A generator who either generates acute hazardous waste or non-acute hazardous waste in a calendar month shall determine its generator category for that month by doing all of the following: NR 662.013(1)(a)(a) Counting the total amount of hazardous waste generated in the calendar month. NR 662.013(1)(b)(b) Subtracting from the total any amounts of waste exempt from counting as described in subs. (3) and (4). NR 662.013(1)(c)(c) Determining the resulting generator category for the hazardous waste generated using Table 1. NR 662.013(2)(2) Generators of both acute and non-acute hazardous wastes. A generator who generates both acute hazardous waste and non-acute hazardous waste in the same calendar month shall determine its generator category for that month by doing all of the following: NR 662.013(2)(a)(a) Counting separately the total amount of acute hazardous waste and the total amount of non-acute hazardous waste generated in the calendar month. NR 662.013(2)(b)(b) Subtracting from each total any amounts of waste exempt from counting as described in subs. (3) and (4). NR 662.013(2)(c)(c) Determining separately the resulting generator categories for the quantities of acute and non-acute hazardous waste generated using Table 1. NR 662.013(2)(d)(d) Comparing the resulting generator categories from par. (c) and applying the more stringent generator category to the accumulation and management of both non-acute hazardous waste and acute hazardous waste generated for that month. Table 1
Generator Categories Based on Quantity of Waste Generated in a Calendar Month
NR 662.013(3)(3) Monthly quantity-based determinations. When making the monthly quantity-based determinations required under this chapter, the generator shall include all hazardous waste that it generates, except hazardous waste that is any of the following: NR 662.013(3)(b)(b) Managed immediately upon generation in on-site elementary neutralization units, wastewater treatment units, or totally enclosed treatment facilities as defined in s. NR 660.10. NR 662.013(3)(h)(h) Managed as part of an episodic event in compliance with the conditions under subch. L. NR 662.013(3)(i)(i) A hazardous waste pharmaceutical, as defined in s. NR 666.500, that is subject to or managed in accordance with subch. P of ch. NR 666 or is a hazardous waste pharmaceutical that is also a drug enforcement administration controlled substance and is conditionally exempt under s. NR 666.506. NR 662.013(4)(4) Determining the quantity of hazardous waste generated in a calendar month. In determining the quantity of hazardous waste generated in a calendar month, a generator need not include any of the following: NR 662.013(4)(a)(a) Hazardous waste when it is removed from on-site accumulation, so long as the hazardous waste was previously counted once. NR 662.013(4)(b)(b) Hazardous waste generated by on-site treatment, including reclamation, of the generator’s hazardous waste, so long as the hazardous waste that is treated was previously counted once. NR 662.013(4)(c)(c) Hazardous waste spent materials that are generated, reclaimed, and subsequently reused on-site, so long as the spent materials were previously counted once. NR 662.013(5)(5) Generator category. Based on the generator category as determined under this section, the generator shall meet the applicable independent requirements listed in s. NR 662.010. A generator’s category also determines which of the provisions specified in s. NR 662.014, 662.015, 662.016, or 662.017 shall be met to obtain an exemption from the storage facility license, interim status, and operating requirements when accumulating hazardous waste.
