Register August 2020 No. 776
The treatment standard for many characteristic wastes is stated in the s.
NR 668.40 Table of Treatment Standards as “Deactivation and meet UTS." The department has determined that many technologies, when used alone or in combination, can achieve the deactivation portion of the treatment standard. Characteristic wastes that are not managed in a facility regulated by ch.
283, Stats., or in a CWA-equivalent facility, and that also contain underlying hazardous constituents (see s.
NR 668.02 (9)) shall be treated not only by a “deactivating" technology to remove the characteristic, but also to achieve the universal treatment standards (UTS) for underlying hazardous constituents. The following appendix presents a partial list of technologies, utilizing the 5 letter technology codes established in s.
NR 668.42, Table 1, that may be useful in meeting the treatment standard. Use of these specific technologies is not mandatory and does not preclude direct reuse, recovery or the use of other pretreatment technologies, provided deactivation is achieved and underlying hazardous constituents are treated to achieve the UTS.
