NR 661.0021 HistoryHistory: CR 19-082: cr. Register August 2020 No. 776, eff. 9-1-20; correction in (1) (a) made under s. 35.17, Stats., Register August 2020 No. 776.

NR 661.0022(1)(1) A solid waste exhibits the characteristic of corrosivity if a representative sample of the waste has either of the following properties:

NR 661.0022(1)(a)(a) It is aqueous and has a pH less than or equal to 2 or greater than or equal to 12.5, as determined by a pH meter using Method 9040C in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW-846, as incorporated by reference in s. NR 660.11.

NR 661.0022(1)(b)(b) It is a liquid and corrodes SAE 1020 steel at a rate greater than 6.35 mm per year at a test temperature of 55°C as determined by Method 1110A in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW-846, and as incorporated by reference in s. NR 660.11.

NR 661.0022(2)(2) A solid waste that exhibits the characteristic of corrosivity has the EPA hazardous waste number of D002.

NR 661.0023(1)(1) A solid waste exhibits the characteristic of reactivity if a representative sample of the waste has any of the following properties:

NR 661.0023(1)(d)(d) When mixed with water, it generates toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment.

NR 661.0023(1)(e)(e) It is a cyanide or sulfide bearing waste which, when exposed to pH conditions between 2 and 12.5, can generate toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment.

NR 661.0023(1)(f)(f) It is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement.

NR 661.0023(1)(h)(h) It is a forbidden explosive as defined in 49 CFR 173.54, or is a Division 1.1, 1.2 or 1.3 explosive as defined in 49 CFR 173.50 and 173.53, incorporated by reference in s. Trans 326.01.

NR 661.0023(2)(2) A solid waste that exhibits the characteristic of reactivity has the EPA hazardous waste number of D003.

NR 661.0024(1)(1) A solid waste, except manufactured gas plant waste, exhibits the characteristic of toxicity if, using the Toxicity Characteristic leaching procedure, test Method 1311 in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW-846, as incorporated by reference in s. NR 660.11, the extract from a representative sample of the waste contains any of the contaminants listed in Table 2 at the concentration equal to or greater than the respective value given in that table. Where the waste contains less than 0.5 percent filterable solids, the waste itself, after filtering using the methodology outlined in Method 1311, is considered to be the extract for the purpose of this section.

NR 661.0024(2)(2) A solid waste that exhibits the characteristic of toxicity has the EPA hazardous waste number specified in Table 1 which corresponds to the toxic contaminant causing it to be hazardous.

3If o-, m-, and p-Cresol concentrations cannot be differentiated, the total cresol, D026, concentration is used. The regulatory level of total cresol is 200 mg/l.
