 Title 22. Social Security
 Division 4.5. Environmental Health Standards for the Management of Hazardous Waste
 Chapter 18. Land Disposal Restrictions
 Article 4. Treatment Standards

  § 66268.48. Universal Treatment Standards.  

Latest version.
  • (a) 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 section 66260.10, 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 and/or regulated constituents are described as a combination of a chemical with it's salts and/or esters, the CAS number is given for the parent compound only.
    (2) Concentration standards for wastewaters are expressed in mg/l 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 in accordance with the technical requirements of Title 22, CCR, chapter 14, article 15 or chapter 15, article 15, or based upon combustion in fuel substitution units operating in accordance with applicable technical requirements. A facility may comply with these treatment standards according to provisions in section 66268.40(d). 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 9010 or 9012, found in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” USEPA Publication SW-846, as incorporated by reference in section 66260.11, 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 in section 66260.10.
    (7) This constituent is not an underlying hazardous constituent as defined in section 66260.10 of this division because its UTS level is greater than its TC level, thus a treated 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-D011 only.
    NOTE: NA means not applicable.
