Emergency Revision of the Land Disposal Restrictions (LDR) Phase III Treatment Standards for Listed Hazardous Wastes From Carbamate Production

AGENCY: Environmental Protection Agency (EPA, the Agency).

ACTION: Immediate final rule.  

SUMMARY: On April 8, 1996, EPA published treatment standards (the "Phase III" final rule) for a number of hazardous wastes associated with the production of carbamate pesticides ("carbamate wastes") (61 FR 15566, April 8, 1996). The treatment standards were expressed as levels of chemical constituents that had to be measured in treatment residues before land disposal. They became effective July 8, 1996.
	The Agency recently has become aware, however, of a serious analytic monitoring problem associated with the carbamate constituent treatment standards. Laboratory standards (chemicals used to calibrate laboratory instruments) do not exist for every carbamate constituent.  Since commercial laboratories currently are unable to analyze all of the carbamate waste constituents, treatment facilities cannot certify that the LDR treatment standards have been achieved. Today's final rule revises the carbamate waste treatment standards for one year from the date of publication by allowing carbamate wastes to be treated either by any technology which achieves the constituent concentration levels promulgated in the Phase III rule, or by treatment technologies specified in this final rule as alternative treatment standards. This rule also suspends the requirement to treat carbamate waste constituents when they are expected to be present in ignitable, corrosive, reactive or toxic hazardous wastes as "underlying hazardous constituents."  
	The Agency believes that these temporary alternative treatment standards will assure that carbamate wastes are adequately treated prior to land disposal, while providing time for analytic chemical standards to be developed. At the end of the year EPA expects that laboratories will be able to perform the analyses necessary to measure compliance with treatment levels. At that time, therefore, the LDR treatment standards for carbamate wastes will revert to those originally promulgated in the Phase III rule.

EFFECTIVE DATE: August 26, 1996.

Notes to the Table: 

1 The waste descriptions provided in this table do not replace waste descriptions in 40 CFR part 261. 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 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 40 CFR 268.42 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 40 CFR Part 264, Subpart O, or Part 265, Subpart O, 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 40 CFR 268.40(d). All concentration standards for nonwastewaters are based on analysis of grab samples.

       *          *          *          *          *          *          *

10 Between August 26, 1996 and August 27, 1997, the treatment standard for this waste may be satisfied by either meeting the constituent concentrations if this table or by treating the waste by the specified technologies: combustion, as defined by the technology code CMBST at § 268.42 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 § 268.42 Table 1, for wastewaters.

    4. In § 268.48, the table in paragraph (a) is amended by adding footnote number "6" in column one, under the heading Regulated Constituents/Common Name, under I. Organic constituents, after the following chemical names: "2213"; "Aldicarb sulfone"; "Barban"; "Bendiocarb"; "Bendiocarb phenol"; "Benomyl"; "Butylate"; "Carbaryl"; "Carbenzadim"; "Carbofuran"; "Carbofuran phenol"; "Carbosulfan"; "m_Cumenyl methylcarbamate"; "Cycloate"; "Diethylene glycol, dicarbamate"; "Dimetilan"; "Dithiocarbamates (total)"; "EPTC"; "Formetanate hydrochloride"; "Formparanate"; "3_Iodo_2_propynyl n_butylcarbamate"; "Isolan"; "Methiocarb"; "Methomyl"; "Metolcarb"; "Mexacarbate"; "Molinate"; "Oxamyl"; "Pebulate"; "o_Phenylenediamine"; "Physostigmine"; "Physostigmine salicylate"; "Promecarb"; "Propham"; "Propoxur"; "Prosulfocarb"; "Thiodicarb"; "Thiophanate_methyl"; "Tirpate"; "Triallate"; "Triethylamine"; and, "Vernolate"; and adding footnote 6 at the end of the table to read as follows:
