Appendix VI.  


Recommended Technologies to Achieve Deactivation of
Characteristics in Section 66268.42
The treatment standard for many characteristic wastes is stated in the section 66268.40 Table of Treatment Standards as “Deactivation and meet UTS.” USEPA 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 the federal Clean Water Act (CWA) or in a federal CWA-equivalent facility, and that also contain underlying hazardous constituents (see section 66260.10) 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 five letter technology codes established in section 66268.42 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, and/or the use of other pretreatment technologies, provided deactivation is achieved and underlying hazardous constituents are treated to achieve the UTS.
