Treatment Standards for Hazardous Wastes

Note: NA means not applicable

(1) The waste descriptions provided in this table do not replace waste descriptions in Title 22, CCR, chapter 11. Descriptions of Treatment/Regulatory Subcategories are provided, as needed, to distinguish between applicability of different standards.

(2) CAS means Chemical Abstract Services. When the waste code and/or regulated constituents are described as a combination of a chemical with its salts and/or esters, the CAS number is given for the parent compound only.

(3) Concentration standards for wastewaters are expressed in mg/l are based on analysis of composite samples.

(4) All treatment standards expressed as a Technology Code or combination of Technology Codes are explained in detail in section 66268.42 Table 1 -- Technology Codes and Descriptions of Technology-Based Standards.

(5) 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.

(6) Where an alternate treatment standard or set of alternate standards has been indicated, a facility may comply with this alternate standard, but only for the Treatment/Regulatory Subcategory or physical form (i.e., wastewater and/or nonwastewater) specified for that alternate standard.

(7) 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.

(8) These wastes, when rendered nonhazardous and then subsequently managed in federal CWA, or federal CWA-equivalent systems, are not subject to treatment standards. (See section 66268.1(c)(3) and (4)).

(9) These wastes, when rendered nonhazardous and then subsequently injected in a Class I federal Safe Drinking Water Act (SDWA) well, are not subject to treatment standards.

(10) The treatment standard for this waste may be satisfied by either meeting the constituent concentrations in this table or by treating the waste by the specified technologies: combustion, as defined by the technology code CMBST in section 66268.42 Table 1 of this chapter, for nonwastewaters; and, biodegradation as defined by the technology code BIODG, carbon adsorption as defined by the technology code CARBN, chemical oxidation as defined by the technology code CHOXD, or combustion as defined as technology code CMBST in section 66268.42 Table 1 of this chapter, for wastewaters.

(11) For these wastes, the definition of CMBST is limited to:

(1) combustion units operating under CCR, Title 22, chapter 16,

(2) combustion units permitted under CCR, Title 22, chapter 14, article 15, or

(3) combustion units operating under CCR, Title 22, chapter 15, article 15, which have obtained a determination of equivalent treatment under section 66268.42(b).

(12) Disposal of K175 wastes that have complied with all applicable section 66268.40 treatment standards must also be macroencapsulated in accordance with 66268.45 Table 1 unless the waste is placed in:

(1) A RCRA Subtitle C monofill containing only K175 wastes that meet all applicable section 66268.40 treatment standards; or

(2) A dedicated RCRA Subtitle C landfill cell in which all other wastes being co-disposed are at pH[LESS THAN EQUAL TO]6.0.

NOTE: NA means not applicable.
