Register August 2020 No. 776, eff. 9-1-20; correction in (Table) made under s. 35.17, Stats., Register August 2020 No. 776. NR 661.0032NR 661.0032 Hazardous wastes from specific sources. NR 661.0032(1)(1) Listed hazardous wastes from specific sources. The following solid wastes are listed hazardous wastes from specific sources unless they are excluded under ss. NR 660.20 and 660.22 and listed in 40 CFR part 261, Appendix IX: NR 661.0032(2)(2) Listing specific definitions. For the purposes of the K181 listing under sub. (3), dyes or pigments production is defined to include manufacture of the following product classes: dyes, pigments, or FDA certified colors that are classified as azo, triarylmethane, perylene or anthraquinone classes. Azo products include azo, monoazo, diazo, triazo, polyazo, azoic, benzidine, and pyrazolone products. Triarylmethane products include both triarylmethane and triphenylmethane products. Wastes that are not generated at a dyes or pigments manufacturing site, such as wastes from the off-site use, formulation, and packaging of dyes or pigments, are not included in the K181 listing. NR 661.0032(3)(3) K181 listing levels. Nonwastewaters containing constituents in amounts equal to or exceeding the following levels during any calendar year are subject to the K181 listing, unless the conditions in the K181 listing are met. NR 661.0032(4)(4) Procedures for demonstrating that dyes or pigment nonwastewaters are not K181. The procedures described in pars. (a) to (c) and (e) establish when nonwastewaters from the production of dyes or pigments would not be hazardous. These procedures apply to wastes that are not disposed in landfill units or treated in combustion units as specified in sub. (1). If the nonwastewaters are disposed in landfill units or treated in combustion units as described in sub. (1), then the nonwastewaters are not hazardous. In order to demonstrate that it is meeting the landfill disposal or combustion conditions contained in the K181 listing description, the generator shall maintain documentation as described in par. (d). NR 661.0032(4)(a)(a) Determination based on no K181 constituents. A generator that has knowledge, such as knowledge of constituents in wastes based on prior sampling and analysis data or information about raw materials used, production processes used, and reaction and degradation products formed, that its wastes contain none of the K181 constituents listed in sub. (3) can use its knowledge to determine that its waste is not K181. The generator shall document the basis for all such determinations on an annual basis and keep each annual documentation for 3 years. NR 661.0032(4)(b)(b) Determination for generated quantities of 1,000 metric tons a year or less for wastes that contain K181 constituents. If the total annual quantity of dyes or pigment nonwastewaters generated is 1,000 metric tons or less, the generator can use knowledge of the wastes, such as knowledge of constituents in wastes based on prior analytical data or information about raw materials used, production processes used, and reaction and degradation products formed, to conclude that annual mass loadings for the K181 constituents are below the listing levels of sub. (3). To make this determination, the generator shall do all of the following: NR 661.0032(4)(b)1.1. Each year document the basis for determining that the annual quantity of nonwastewaters expected to be generated will be less than 1,000 metric tons. NR 661.0032(4)(b)2.2. Track the actual quantity of nonwastewaters generated from January 1 through December 31 of each year. If, at any time within the year, the actual waste quantity exceeds 1,000 metric tons, the generator shall comply with the requirements under par. (c) for the remainder of the year. NR 661.0032(4)(b)3.3. Keep a running total of the K181 constituent mass loadings over the course of the calendar year. NR 661.0032(4)(b)4.4. Keep all of the following records on-site for the 3 most recent calendar years in which the hazardous waste determinations are made: NR 661.0032(4)(b)4.c.c. The calculations performed to determine annual total mass loadings for each K181 constituent in the nonwastewaters during the year. NR 661.0032(4)(c)(c) Determination for generated quantities greater than 1,000 metric tons a year for wastes that contain K181 constituents. If the total annual quantity of dyes or pigment nonwastewaters generated is greater than 1,000 metric tons, the generator shall perform all of the following steps in order to make a determination that its waste is not K181: NR 661.0032(4)(c)1.1. Determine which K181 constituents listed in sub. (3) are reasonably expected to be present in the wastes based on knowledge of the wastes, such as based on prior sampling and analysis data or information about raw materials used, production processes used, and reaction and degradation products formed. NR 661.0032(4)(c)2.2. If 1,2-phenylenediamine is present in the wastes, the generator can use either knowledge or sampling and analysis procedures to determine the level of this constituent in the wastes. For determinations based on use of knowledge, the generator shall comply with the procedures for using knowledge described in par. (b) and keep the records described in par. (b) 4. For determinations based on sampling and analysis, the generator shall comply with all of the sampling and analysis and recordkeeping requirements in subds. 3. to 11. NR 661.0032(4)(c)3.3. Develop a waste sampling and analysis plan or modify an existing plan to collect and analyze representative waste samples for the K181 constituents reasonably expected to be present in the wastes. At a minimum, the plan shall include all of the following: NR 661.0032(4)(c)3.c.c. A discussion of how the sampling plan accounts for potential temporal and spatial variability of the wastes. NR 661.0032(4)(c)3.d.d. A detailed description of the test methods to be used, including sample preparation, clean up, if necessary, and determinative methods. NR 661.0032(4)(c)4.4. Collect and analyze samples in accordance with the waste sampling and analysis plan. NR 661.0032(4)(c)4.a.a. The sampling and analysis shall be unbiased, precise, and representative of the wastes. NR 661.0032(4)(c)4.b.b. The analytical measurements shall be sufficiently sensitive, accurate and precise to support any claim that the constituent mass loadings are below the listing levels of sub. (3). NR 661.0032(4)(c)6.6. Record the waste quantity represented by the sampling and analysis results. NR 661.0032(4)(c)7.7. Calculate constituent-specific mass loadings, product of concentrations and waste quantity. NR 661.0032(4)(c)8.8. Keep a running total of the K181 constituent mass loadings over the course of the calendar year. NR 661.0032(4)(c)9.9. Determine whether the mass of any of the K181 constituents listed in sub. (3) generated between January 1 and December 31 of any year is below the K181 listing levels. NR 661.0032(4)(c)10.10. Keep all of the following records on site for the 3 most recent calendar years in which the hazardous waste determinations are made: NR 661.0032(4)(c)11.11. Nonhazardous waste determinations shall be conducted annually to verify that the wastes remain nonhazardous. NR 661.0032(4)(c)11.a.a. The annual testing requirements are suspended after 3 consecutive successful annual demonstrations that the wastes are nonhazardous. The generator can then use knowledge of the wastes to support subsequent annual determinations. NR 661.0032(4)(c)11.b.b. The annual testing requirements are reinstated if the manufacturing or waste treatment processes generating the wastes are significantly altered, resulting in an increase of the potential for the wastes to exceed the listing levels. NR 661.0032(4)(c)11.c.c. If the annual testing requirements are suspended, the generator shall keep records of the process knowledge information used to support a nonhazardous determination. If testing is reinstated, a description of the process change shall be retained. NR 661.0032(4)(d)(d) Recordkeeping for the landfill disposal and combustion exemptions. For the purposes of meeting the landfill disposal and combustion condition set out in the K181 listing description, the generator shall maintain on site for 3 years documentation demonstrating that each shipment of waste was received by a landfill unit that is subject to or meets the landfill design standards set out in the listing description, or was treated in combustion units as specified in the listing description. NR 661.0032(4)(e)(e) Waste holding and handling. During the interim period, from the point of generation to completion of the hazardous waste determination, the generator is responsible for storing the wastes appropriately. If the wastes are determined to be hazardous and the generator has not complied with the hazardous waste requirements during the interim period, the generator may be subject to an enforcement action for improper management.
