Section 668.40. Applicability of treatment standards.

 

(1)  A prohibited waste identified in the table "Treatment Standards for Hazardous Wastes" in this section may be land disposed only if it meets the requirements found in the table. For each waste, the table identifies one of the following three types of treatment standard requirements:

(a) All hazardous constituents in the waste or in the treatment residue shall be at or below the values found for that waste in the table under the heading "total waste standards".

(b) The hazardous constituents in the extract of the waste or in the extract of the treatment residue shall be at or below the values found in the table under the heading, "waste extract standards".

(c) The waste shall be treated using the technology specified in the table under the heading "technology standard", and described in detail in s. NR 668.42 , Table 1—Technology Codes and Description of Technology-Based Standards.

(2)  For wastewaters, compliance with concentration level standards is based on maximums for any one day, except for D004 through D011 wastes for which the previously promulgated treatment standards based on grab samples remain in effect. For all nonwastewaters, compliance with concentration level standards is based on grab sampling. For wastes covered by the waste extract standards, the test method 1311, the toxicity characteristic leaching procedure found in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", EPA SW-846, incorporated by reference in s. NR 660.11 shall be used to measure compliance. An exception is made for D004 and D008, for which either of two test methods may be used: Method 1311 or Method 1310, the extraction procedure toxicity test. For wastes covered by a technology standard, the wastes may be land disposed after being treated using that specified technology or an equivalent treatment technology approved by the EPA Administrator under the procedures set forth in 40 CFR 268.42 (b).

(3)  When wastes with differing treatment standards for a constituent of concern are combined for purposes of treatment, the treatment residue shall meet the lowest treatment standard for the constituent of concern.

(4)  Notwithstanding the prohibitions specified in sub. (1) , treatment and disposal facilities may demonstrate and certify pursuant to s. NR 668.07 (2) (e) compliance with the treatment standards for organic constituents specified by a footnote in the table "Treatment Standards for Hazardous Wastes" in this section, provided all of the following conditions are satisfied:

(a) The treatment standards for the organic constituents were established based on incineration in units operated in accordance with the technical requirements of subch. O of ch. NR 664 , or based on combustion in fuel substitution units operating in accordance with applicable technical requirements.

(b) The treatment or disposal facility has used the methods referenced in par. (a) to treat the organic constituents.

(c) The treatment or disposal facility may demonstrate compliance with organic constituents if good-faith analytical efforts achieve detection limits for the regulated organic constituents that do not exceed the treatment standards specified in this section by an order of magnitude.

(5)  For characteristic wastes (D001 to D043) that are subject to treatment standards in the table "Treatment Standards for Hazardous Wastes," and are not managed in a wastewater treatment system that is regulated under ch. 283 , Stats. , or that is CWA-equivalent, all underlying hazardous constituents as defined in s. NR 668.02 (9) must meet universal treatment standards, found in s. NR 668.48 , Table Universal Treatment Standards, prior to land disposal as defined in s. NR 668.02 (3) .

(6)  The treatment standards for F001 to F005 nonwastewater constituents carbon disulfide, cyclohexanone, and methanol apply to wastes which contain only one, 2, or 3 of these constituents. Compliance is measured for these constituents in the waste extract from test Method 1311, the Toxicity Characteristic Leaching Procedure found in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", EPA SW-846, incorporated by reference in s. NR 660.11 . If the waste contains any of these three constituents along with any of the other 25 constituents found in F001 to F005, then compliance with treatment standards for carbon disulfide, cyclohexanone, and methanol are not required.

(7)  Between August 26, 1996 and March 4, 1999 the treatment standards for the wastes specified in s. NR 661.32 as EPA hazardous waste numbers K156 to K161 and in s. NR 661.33 as EPA hazardous waste numbers P127, P128, P185, P188 to P192, P194, P196 to P199, P201 to P205, U271, U277 to U280, U364 to U367, U372, U373, U375 to U379, U381 to U387, U389 to U396, U400 to U404, U407, and U409 to U411; and soil contaminated with these wastes; shall be satisfied by either meeting the constituent concentrations presented in the table "Treatment Standards for Hazardous Wastes" in this section, or by treating the waste by the following technologies: combustion, as defined by the technology code CMBST at s. NR 668.42 , Table 1, 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 at s. NR 668.42 , Table 1, for wastewaters.

(8)  If prohibited D004 to D011 mixed radioactive wastes and mixed radioactive listed wastes containing metal constituents, have been previously treated by stabilization to the treatment standards in effect at that time and put into storage afterwards, then it is not necessary to re-treat the waste to meet treatment standards in this section prior to land disposal.

(10)  Effective September 4, 1998, the treatment standards for the wastes specified in s. NR 661.33 as EPA hazardous waste numbers P185, P191, P192, P197, U364, U394, and U395 shall be satisfied by either meeting the constituent concentrations presented in the table "Treatment Standards for Hazardous Wastes" in this section, or by treating the waste by the following technologies: combustion, as defined by the technology code CMBST at s. NR 668.42 , Table 1, for nonwastewaters; 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 at s. NR 668.42 , Table 1, for wastewaters.

CR 05-032 : cr. Register July 2006 No. 607 , eff. 8-1-06. Section NR 668.40 — Treatment Standards for Hazardous Wastes NA means not applicable. - See PDF for table 1 The waste descriptions provided in this table do not replace waste descriptions in ch. NR 661 . 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 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. 3 Concentration standards for wastewaters are expressed in mg/L and 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 s. NR 668.42 , 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 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. 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 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", 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. 8 These wastes, when rendered nonhazardous and then subsequently managed under ch. 283 , Stats., or CWA-equivalent systems are not subject to treatment standards (see s. NR 668.01 (3) (d) ). 9 These wastes, when rendered nonhazardous and then subsequently injected in a Class SDWA well, are not subject to treatment standards (see NR 665 subch. R). 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 at s. NR 668.42 , Table 1, 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 at s. NR 668.42 , Table 1, for wastewaters. 11 For these wastes, the definition of CMBST is limited to: (1) combustion units operating under ch. NR 666 , (2) combustion units licensed under subch. O of ch. NR 664 , or (3) combustion units licensed under subch. O of ch. NR 665 which have obtained a determination of equivalent treatment under 40 CFR 268.42 (b). 12 Disposal of K175 wastes that have complied with all applicable s. NR 668.40 treatment standards must also be macroencapsulated in accordance with s. NR 668.45 , Table 1 unless the waste is placed in one of the following: (1) A hazardous waste monofill containing only K175 wastes that meet all applicable s. NR 668.40 treatment standards. (2) A dedicated hazardous waste landfill cell in which all other wastes being co-disposed are at pH = 6.0. 13 "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", EPA SW-846, incorporated by reference in s.
