NR 600-699 - Environmental Protection - Hazardous Waste Management
Chapter NR 668 - Hazardous Waste Land Disposal Restrictions
Subchapter D - Treatment Standards
Section NR 668.48 - Universal treatment standards
Current through August 26, 2024
(1) Table UTS identifies the hazardous constituents, along with the nonwastewater and wastewater treatment standard levels, that are used to regulate most prohibited hazardous wastes with numerical limits. For determining compliance with treatment standards for underlying hazardous constituents as defined in s. NR 668.02(9), these treatment standards may not be exceeded. Compliance with these treatment standards is measured by an analysis of grab samples, unless otherwise noted in the following Table UTS.

1 CAS means Chemical Abstract Services. When the waste code or regulated constituents are described as a combination of a chemical with its salts or esters, the CAS number is given for the parent compound only.
2 Concentration standards for wastewaters are expressed in mg/L and are based on analysis of composite samples.
3 Except for metals (EP or TCLP) and cyanides (total and amenable) the nonwastewater treatment standards expressed as a concentration were established, in part, based upon incineration in units operated according to the technical requirements of subch. O of ch. NR 664 or subch. O of ch. NR 665, or based upon combustion in fuel substitution units operating according to applicable technical requirements. A facility may comply with these treatment standards according to s. NR 668.40(4). All concentration standards for nonwastewaters are based on analysis of grab samples.
4 Both cyanides (total) and cyanides (amenable) for nonwastewaters are to be analyzed using Method 9010C or 9012B, found in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA SW-846, incorporated by reference in s. NR 660.11, with a sample size of 10 grams and a distillation time of one hour and 15 minutes.
5 These constituents are not "underlying hazardous constituents" in characteristic wastes, according to the definition at s. NR 668.02(9).
7 This constituent is not an underlying hazardous constituent as defined at s. NR 668.02(9) because its UTS level is greater than its TC level, thus a treatment selenium waste would always be characteristically hazardous, unless it is treated to below its characteristic level.
8 This standard is temporarily deferred for soil exhibiting a hazardous characteristic due to D004 to D011 only.
