Land Disposal Restrictions Phase III--Decharacterized Wastewaters, Carbamate Wastes, and Spent Potliners  

AGENCY: Environmental Protection Agency (EPA).  

ACTION: Final rule.

SUMMARY: EPA is promulgating treatment standards for hazardous wastes from the production of carbamate pesticides and from primary aluminum production under its Land Disposal Restrictions (LDR) program. The purpose of the LDR program, authorized by the Resource Conservation and Recovery Act (RCRA), is to minimize short- and long-term threats to human health and the environment due to land disposal of hazardous wastes. 

	The Agency is also amending the treatment standards for hazardous wastes that exhibit the characteristic of reactivity. The rule also begins the process of amending existing treatment standards for wastewaters which are hazardous because they display the characteristic of ignitability, corrosivity, reactivity, or toxicity. These wastes are sometimes treated in lagoons whose ultimate discharge is regulated under the Clean Water Act, and sometimes injected into deepwells which are regulated under the Safe Drinking Water Act. Prior to today's rule, the treatment standard for these wastes required only removal of the characteristic property. Today's revised treatment standards require treatment, not only to remove the characteristic, but also to treat any underlying hazardous constituents which may be present in the wastes. Therefore, these revised treatment standards will minimize threats from exposure to hazardous constituents which may potentially migrate from these lagoons or wells. Finally, EPA is codifying as a rule its existing Enforcement Policy that combustion of inorganic wastes is an impermissible form of treatment because hazardous constituents are being diluted rather than effectively treated.  

EFFECTIVE DATE: This final rule is effective on April 8, 1996, except: Sections 148.18(a), 268.39(a), (b), and (f), which are effective on July 1, 1996; and Sections 148.18(b) and 268.39(c), which are effective on January 8, 1997; and Sections 148.1 (a), (b), and (d), 148.3, 148.4, 148.18 (c) and (d), 148.20(a), 268.1(e), 268.2 (k) and (l), 268.3 (a) and (b), 268.9 (d), (e), (f), and (g), 268.39 (d) and (e), 268.44(a), and 403.5 (c) and (d), which are effective on April 8, 1998.

Subpart A--General  

	8. Section 268.1 is amended in paragraph (e)(3) by removing the period at the end of the paragraph and adding ``; or'' in its place, by revising paragraph (e)(4) and by removing paragraph (e)(5) to read as follows:  

§ 268.1 Purpose, scope and applicability. 
*   *   *   *   *
	 (e) * * *
	 (4) De minimis losses of characteristic wastes to wastewaters are not considered to be prohibited wastes and are defined as: 
	(i) Losses from normal material handling operations (e.g. spills from the unloading or transfer of materials from bins or other containers, leaks from pipes, valves or other devices used to transfer materials); minor leaks of process equipment, storage tanks or containers; leaks from well-maintained pump packings and seals; sample purgings; and relief device discharges; discharges from safety showers and rinsing and cleaning of personal safety equipment; rinsate from empty containers or from containers that are rendered empty by that rinsing; and laboratory wastes not exceeding one per cent of the total flow of wastewater into the facility's headworks on an annual basis, or with a combined annualized average concentration not exceeding one part per million in the headworks of the facility's wastewater treatment or pretreatment facility; or 
	(ii) Decharacterized wastes which are injected into Class I nonhazardous wells which wastes combined volume is less than one per cent of the total flow at the wellhead on an annualized basis, is no greater than 10,000 gallons per day, and in which any underlying hazardous constituents in the characteristic wastes are present at the point of generation at levels less than ten times the treatment standards found at § 268.48.

*   *   *   *   *
	9.  Section 268.2 is amended by revising paragraphs (f) and (i), and by adding paragraphs (j), (k), and (l) to read as follows:

*   *   *   *   * 
	(i) "Underlying hazardous constituent" means any constituent listed in § 268.48, Table UTS--Universal Treatment Standards, except fluoride, vanadium, and zinc, which can reasonably be expected to be present at the point of generation of the hazardous waste, at a concentration above the constituent-specific UTS treatment standards. 
	(j) "Inorganic metal-bearing waste" is one for which EPA has established treatment standards for metal hazardous constituents, and which does not otherwise contain significant organic or cyanide content as described in § 268.3(b)(1), and is specifically listed in appendix XI of this part.
	(k) "End-of-pipe" refers to the point where effluent is discharged to the environment. 
	(l) "Stormwater impoundments" are surface impoundments which receive wet weather flow, and only receive process waste during wet weather events. 

	10. Section 268.3 is revised to read as follows:  
§ 268.3 Dilution prohibited as a substitute for treatment.  	(a) No generator, transporter, handler, or owner or operator of a treatment, storage, or disposal facility shall in any way dilute a restricted waste or the residual from treatment of a restricted waste as a substitute for adequate treatment to achieve compliance with subpart D of this part, to circumvent the effective date of a prohibition in subpart C of this part, to otherwise avoid a prohibition in subpart C of this part, or to circumvent a land disposal prohibition imposed by RCRA section 3004. 
	(b) Dilution of wastes that are hazardous only because they exhibit a hazardous characteristic in a treatment system which treats wastes subsequently discharged to a water of the United States pursuant to a permit issued under section 402 of the Clean Water Act (CWA), or which treats wastes for the purposes of pretreatment requirements under section 307 of the CWA, or zero discharge systems with wastewater treatment equivalent to these systems, is not impermissible dilution, so long as the § 268.48 universal treatment standards are met at the point of discharge, or at a prior point of compliance specified under a CWA permit, for all underlying hazardous constituents reasonably expected to be present at the point of generation of the hazardous waste. 
	(c) Combustion of the hazardous waste codes listed in Appendix XI of this part is prohibited, unless the waste, at the point of generation, or after any bona fide treatment such as cyanide destruction prior to combustion, can be demonstrated to comply with one or more of the following criteria (unless otherwise specifically prohibited from combustion): 
	(1) the waste contains hazardous organic constituents or cyanide at levels exceeding the constituent-specific treatment standard found in § 268.48; 
	(2) The waste consists of organic, debris-like materials (e.g., wood, paper, plastic, or cloth) contaminated with an inorganic metal-bearing hazardous waste;

§ 268.8 [Removed and reserved]  
	12. Section 268.8 is removed and reserved. 
	13. Section 268.9 is amended by revising paragraphs (a), (d) introductory text, (d)(1)(i), and (d)(1)(ii), and by adding paragraphs (d)(3), (e), (f), and (g) to read as follows:  

§ 268.9 Special rules regarding wastes that exhibit a characteristic.  
	(a) The initial generator of a solid waste must determine each EPA Hazardous Waste Number (waste code) applicable to the waste in order to determine the applicable treatment standards under subpart D of this part. For purposes of this part 268, the waste will carry the waste code for any applicable listing under 40 CFR part 261, subpart D. In addition, the waste will carry one or more of the waste codes under 40 CFR part 261, subpart C, where the waste exhibits a characteristic, except in the case when the treatment standard for the waste code listed in 40 CFR part 261, subpart D operates in lieu of the standard for the waste code under 40 CFR part 261, subpart C, as specified in paragraph (b) of this section. If the generator determines that his waste displays a hazardous characteristic (and the waste is not a D004--D011 waste, a High TOC D001, or is not treated by CMBST, or RORGS of § 268.42, Table 1), the generator must determine what underlying hazardous constituents (as defined in § 268.2), are reasonably expected to be present above the universal treatment standards found in § 268.48. 
*   *   *   *   * 
	(d) Wastes that exhibit a characteristic are also subject to § 268.7 requirements, except that once the waste is no longer hazardous, a one-time notification and certification must be placed in the generators or treaters files and sent to the EPA region or authorized state, except for those facilities discussed in paragraph (f) of this section. The notification and certification that is placed in the generators or treaters files must be updated if the process or operation generating the waste changes and/or if the Subtitle D facility receiving the waste changes. However, the generator or treater need only notify the EPA region or an authorized state on an annual basis if such changes occur. Such notification and certification should be sent to the EPA region or authorized state by the end of the calendar year, but no later than December 31. 
	(1) * * * 
	(i) For characteristic wastes other than those managed on site in a wastewater treatment system subject to the Clean Water Act (CWA), zero-dischargers engaged in CWA-equivalent treatment, or Class I nonhazardous injection wells, the name and address of the Subtitle D facility receiving the waste shipment; and 
	(ii) For all characteristic wastes, a description of the waste as initially generated, including the applicable EPA Hazardous Waste Number(s), treatability group(s), and underlying hazardous constituents.
*   *   *   *   * 
	(3) For characteristic wastes whose ultimate disposal will be into a Class I nonhazardous injection well, and compliance with the treatment standards found in § 268.48 for underlying hazardous constituents is achieved through pollution prevention that meets the criteria set out at 40 CFR 148.1(d), the following information must also be included: 
	(i) A description of the pollution prevention mechanism and when it was implemented if already complete; 
	(ii) The mass of each underlying hazardous constituent before pollution prevention; 
	(iii) The mass of each underlying hazardous constituent that must be removed, adjusted to reflect variations in mass due to normal operating conditions; and 
	(iv) The mass reduction of each underlying hazardous constituent that is achieved. 
	(e) For decharacterized wastes managed on-site in a wastewater treatment system subject to the Clean Water Act (CWA) or zero-dischargers engaged in CWA-equivalent treatment, compliance with the treatment standards found at § 268.48 must be monitored quarterly, unless the treatment is aggressive biological treatment, in which case compliance must be monitored annually. Monitoring results must be kept in on-site files for 5 years. 
	(f) For decharacterized wastes managed on-site in a wastewater treatment system subject to the Clean Water Act (CWA) for which all underlying hazardous constituents (as defined in § 268.2), are addressed by a CWA permit, this compliance must be documented and this documentation must be kept in on-site files. 
	(g) For characteristic wastes whose ultimate disposal will be into a Class I nonhazardous injection well which qualifies for the de minimis exclusion described in § 268.1, information supporting that qualification must be kept in on-site files.  

§§ 268.10-268.12 [Removed and Reserved]

In addition, soil and debris contaminated with these wastes are prohibited from land disposal.
 	(b) On July 8, 1996 the wastes identified in 40 CFR 261.23 as D003 that are managed in systems other than those whose discharge is regulated under the Clean Water Act (CWA), or that inject in Class I deep wells regulated under the Safe Drinking Water Act (SDWA), or that are zero dischargers that engage in CWA-equivalent treatment before ultimate land disposal, are prohibited from land disposal. This prohibition does not apply to unexploded ordnance and other explosive devices which have been the subject of an emergency response (such D003 wastes are prohibited unless they meet the treatment standard of DEACT before land disposal (see § 268.40)). 
	(c) On July 8, 1996, the wastes specified in 40 CFR 261.32 as EPA Hazardous Waste number K088 are prohibited from land disposal. In addition, soil and debris contaminated with these wastes are prohibited from land disposal. 
	(d) On April 8, 1998, decharacterized wastes managed in surface impoundments whose discharge is regulated under the Clean Water Act (CWA), or decharacterized wastes managed by zero dischargers in surface impoundments or tanks that engage in CWA-equivalent treatment before ultimate land disposal are prohibited from land disposal. The following are exceptions to this requirement: 
	(1) Surface impoundments which are permitted under subtitle C of RCRA; 
	(2) Storm water impoundments as defined in § 268.2;
	(3) Surface impoundments which are part of facilities in the pulp, paper, and paperboard industrial category.
	(e) On April 8, 1998, Radioactive wastes mixed with K088, K156-K161, P127, P128, P185, P188-P192, P194, P196-P199, P201-P205, U271, U277-U280, U364-U367, U372, U373, U375-U379, U381-U387, U389-U396, U400-U404, and U407, U409-U411 are also prohibited from land disposal. In addition, soil and debris contaminated with these radioactive mixed wastes are prohibited from land disposal.
	(f) Between July 8, 1996 and April 8, 1998, the wastes included in paragraphs (a), (b), (c), and (e) of this section may be disposed in a landfill or surface impoundment, only if such unit is in compliance with the requirements specified in § 268.5(h)(2). 
	(g) The requirements of paragraphs (a), (b), (c), (d), and (e) of this section do not apply if: 
	(1) The wastes meet the applicable treatment standards specified in Subpart D of this part; 
	(2) Persons have been granted an exemption from a prohibition pursuant to a petition under § 268.6, with respect to those wastes and units covered by the petition; 
	(3) The wastes meet the applicable alternate treatment standards established pursuant to a petition granted under § 268.44; 
	(4) Persons have been granted an extension to the effective date of a prohibition pursuant to § 268.5, with respect to these wastes covered by the extension. 
	(h) To determine whether a hazardous waste identified in this section exceeds the applicable treatment standards specified in § 268.40, the initial generator must test a sample of the waste extract or the entire waste, depending on whether the treatment standards are expressed as concentrations in the waste extract or the waste, or the generator may use knowledge of the waste. If the waste contains constituents in excess of the applicable Subpart D levels, the waste is prohibited from land disposal, and all requirements of this part 268 are applicable, except as otherwise specified. 

	16. Section 268.40 is amended by revising paragraph (e) and the table at the end of § 268.40 to read as follows:  

§ 268.40 Applicability of treatment standards. 
*   *   *   *   * 
	(e) For characteristic wastes (D001-D043) that are subject to treatment standards in the following table ``Treatment Standards for Hazardous Wastes,'' all underlying hazardous constituents (as defined in § 268.2(i)) must meet Universal Treatment Standards, found in § 268.48, ``Table UTS,'' prior to land disposal. 
	(1) When these wastes are managed in wastewater treatment systems regulated by the Clean Water Act (CWA), compliance with the treatment standards must be achieved no later than ``end-of-pipe'' as defined in § 268.2(k); or 
	(2) When these wastes are managed in CWA-equivalent treatment systems and tank-based systems that discharge onto the land, compliance with the treatment standards must be achieved no later than the point the wastewater is released to the land (e.g., spray irrigation, discharge to dry river beds, placed into evaporation ponds); or

§ 268.44 Variance from a treatment standard.  
	(a) Where the treatment standard is expressed as a concentration in a waste or waste extract and a waste cannot be treated to the specified level, or where the treatment technology is not appropriate to the waste, the generator or treatment facility may petition the Administrator for a variance from the treatment standard. The petitioner must demonstrate that because the physical or chemical properties of the waste differs significantly from wastes analyzed in developing the treatment standard, the waste cannot be treated to specified levels or by the specified methods. The petitioner may also demonstrate that it is treating underlying hazardous constituents in characteristically hazardous wastewaters by sending the waste to a properly designed and operated BAT/PSES system, which may not be achieving the treatment standards found in § 268.48.
