    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

    I. Background
    
    A. Summary of the Statutory Requirements of the 1984 Hazardous and 
    Solid Waste Amendments, and Requirements of the 1993 Consent Decree 
    With the Environmental Defense Fund
    
        The Hazardous and Solid Waste Amendments (HSWA) to the Resource 
    Conservation and Recovery Act (RCRA), enacted on November 8, 1984, 
    largely prohibit the land disposal of untreated hazardous wastes that 
    do not meet treatment standards established by EPA under section 
    3004(m). Once a hazardous waste is prohibited, the statute provides 
    only two options for legal land disposal: meet the treatment standard 
    for the waste prior to land disposal, or dispose of the waste in a land 
    disposal unit that has been found to satisfy the statutory no migration 
    test. A no migration unit is one from which there will be no migration 
    of hazardous constituents for as long as the waste remains hazardous. 
    RCRA sections 3004 (d), (e), (f), (g)(5).
        The amendments also require the Agency to set levels or methods of 
    treatment, if any, which substantially diminish the toxicity of the 
    waste or substantially reduce the likelihood of migration of hazardous 
    constituents from the waste so that short term and long term threats to 
    human health and the environment are minimized. RCRA section 
    3004(m)(1). To date, the Agency has implemented this provision by 
    establishing treatment standards for chemical constituents in hazardous 
    wastes based on the performance of the best demonstrated available 
    technology (BDAT) to treat the waste. EPA may establish treatment 
    standards as specified technologies, as constituent concentration 
    levels in treatment residuals, or both. When treatment standards are 
    set as levels, the regulated community may use any technology not 
    otherwise prohibited (such as impermissible dilution) to treat the 
    waste.
        It should be noted that the Agency has proposed risk-based exit 
    levels--levels at which wastes are no longer considered hazardous for 
    purposes of RCRA subtitle C--for the majority of hazardous constituents 
    found in listed hazardous wastes in the Hazardous Waste Identification 
    Rule (HWIR) (60 FR 66344, December 21, 1995). Wastes meeting these 
    levels either before or after treatment consequently could be disposed 
    in units not subject to RCRA hazardous waste management requirements 
    (e.g., landfills without subtitle C permits). A consent decree approved 
    by the U.S. District Court for the District of Columbia requires EPA to 
    finalize the HWIR exit levels by December 15, 1996. In the same notice, 
    the Agency proposed to allow the exit levels for some constituents to 
    serve as alternative, risk-based LDR treatment standards satisfying the 
    ``minimize threat'' standard of section 3004(m). Where these risk-based 
    levels are higher (less restrictive) than current BDAT treatment 
    standards, they will effectively supersede the BDAT requirements. See 
    Hazardous Waste Treatment Council v. EPA, 886 F.2d 355, 362-63 (D.C. 
    Cir. 1989).
        EPA was required to promulgate land disposal prohibitions and 
    treatment standards by May 8, 1990 for all wastes that were either 
    listed or identified as hazardous at the time of the 1984 amendments 
    (RCRA sections 3004 (d), (e), and (g)(5)), a task EPA completed within 
    the statutory timeframe. EPA was also required to promulgate 
    prohibitions and treatment standards for wastes identified or listed as 
    hazardous after the date of the 1984 amendments within six months after 
    the listing or identification takes effect (RCRA section 3004(g)(4)).
        The Agency did not meet this latter statutory deadline for all of 
    the wastes identified or listed after the 1984 amendments. As a result, 
    a suit was filed by the Environmental Defense Fund (EDF). EPA and EDF 
    signed a consent decree that establishes a schedule for adopting 
    prohibitions and treatment standards for newly identified and listed 
    wastes. (EDF v. Reilly, Cir. No. 89-0598, D.D.C.). EPA also entered 
    into a settlement agreement with the environmental petitioners in 
    Chemical Waste Management v. EPA, 976 F.2d 2 (D.C. Cir. 1992), cert. 
    denied 113 S. Ct. 1961 (1993) regarding the procedural effect of the 
    mandate entered in that case. This settlement calls for EPA to take 
    action to implement the portions of the opinion dealing with 
    centralized management of wastewaters that initially exhibit a 
    hazardous waste characteristic within specified timeframes.
        Today's rule fulfills several provisions of the settlement 
    agreement and proposed consent decree. First, the rule amends the 
    treatment standards for initially characteristic wastewaters managed in 
    centralized wastewater management systems containing land disposal 
    units. Three specific fact patterns are covered by the rule: (1) Where 
    the wastewaters are ultimately discharged and are subject to 
    limitations or standards established under the Clean Water Act (CWA) 
    and the treatment system preceding discharge includes a surface 
    impoundment; (2) where a facility with initially characteristic wastes 
    treats those wastes with CWA-equivalent treatment but ultimately uses a 
    form of land disposal (such as spray irrigation) that is not regulated 
    under the CWA as the final means of disposing of the treated 
    wastewaters; and (3) the initially characteristic wastes are injected 
    into Class 1 non-hazardous deep wells subject to regulation under the 
    Safe Drinking Water Act (SDWA). In all cases, the wastewaters no longer 
    exhibit a characteristic at the point of land disposal. The amended 
    treatment standards require treatment that destroys, immobilizes, or 
    removes the hazardous constituents present in the initially 
    characteristic wastewaters (referred to as ``underlying hazardous
    
    [[Page 15568]]
    constituents'' because these constituents are not typically the reason 
    the waste is classified as hazardous). Treatment of the underlying 
    hazardous constituents is nevertheless required in order to minimize 
    the long-term threats land disposal of these wastes can cause. 976 F.2d 
    at 16-17.
        EPA is fulfilling provisions of the consent decree by promulgating 
    prohibitions and treatment standards for two ``newly listed wastes'' 
    wastes from production of carbamate pesticides, and spent aluminum 
    potliners from primary aluminum production.
        That being said, the risks addressed by the portion of the rule 
    dealing with centralized wastewater management, particularly UIC wells, 
    are very small relative to the risks presented by other environmental 
    conditions or situations. In a time of limited resources, common sense 
    dictates that we deal with higher risk activities first, a principle on 
    which EPA, members of the regulated community, and the public can all 
    agree. For this reason, the Administration is supporting HR 2036, 
    legislation which passed the House of Representatives, that would 
    remove the mandate to automatically apply LDR treatment standards to 
    decharacterized wastes managed in centralized wastewater management 
    situations regulated by the CWA or the SDWA. If this legislation passes 
    in its current form, it would affect the regulations discussed in 
    sections III., IV., and VI.B. of the preamble. It would not affect the 
    other sections of the preamble and rule. The sections of preamble and 
    rule that are affected by the legislation have been granted 2-year 
    national capacity variance (see Secs. 148.18 (c) and (d) and 268.39 (c) 
    and (d)). The sections of preamble and rule not affected by the 
    legislation have more immediate effective dates. If the legislation 
    does pass into law, the Agency could issue an immediately effective 
    final rule remanding the affected portions.
        Nevertheless, the Agency is presently required to set treatment 
    standards for these relatively low risk wastes and disposal practices, 
    although there are other actions and projects with which the Agency 
    could provide greater protection of human health and the environment. 
    At the same time, however, EPA has sought to exercise the full extent 
    of its authority under current law to implement these mandates with 
    significantly lower cost while ensuring protectiveness, such as giving 
    credit for up-stream reductions in hazardous constituents, and crafting 
    limited exemptions for wastewaters containing de minimis amounts of 
    hazardous constituents.
    
    B. Treatment Standards for Hazardous Wastes That Exhibit a 
    Characteristic--The D.C. Circuit's Opinion in Chemical Waste Management 
    v. EPA
    
        In Chemical Waste Management v. EPA, 976 F.2d 2 (D.C. Cir. 1992) 
    cert. denied 113 S. Ct. 1961 (1993), the court made a number of far-
    reaching rulings pertaining to treatment standards for hazardous wastes 
    that are hazardous because they exhibit a characteristic. First, the 
    court held that land disposal restriction requirements can continue to 
    apply to characteristic hazardous wastes even after they no longer 
    exhibit a characteristic. 976 F.2d at 12-14. Second, to satisfy the 
    requirement in RCRA section 3004(m) that treatment address both short-
    term and long-term threats posed by a waste's land disposal, it is not 
    enough that characteristic hazardous wastes be treated to remove the 
    short-term property (viz. ignitability, corrosivity, or reactivity) 
    that makes them hazardous. Long-term threats, in the form of toxic 
    underlying hazardous constituents, also must be addressed. 976 F.2d at 
    16-17. Third (as EPA reads the opinion), the court held that dilution 
    was ordinarily not a permissible means of treating hazardous 
    constituents. Such constituents generally must be destroyed, 
    immobilized, or removed from the waste to satisfy the requirements of 
    section 3004(m), specifically, the requirement that long-term threats 
    be minimized. 976 F.2d at 23, 25 and n. 8; 60 FR at 11706-11708 (March 
    2, 1995). Fourth, centralized wastewater management systems whose 
    discharge is ultimately regulated under the Clean Water Act, and which 
    dilute characteristic hazardous wastes before treatment in surface 
    impoundments, may continue to do so provided the wastewater treatment 
    system destroys, immobilizes, or removes the same volume of hazardous 
    constituents as would be removed, immobilized, or destroyed if the 
    wastes were treated separately. 976 F.2d at 22-24. In other words, 
    notwithstanding that these wastes are disposed in impoundments without 
    being fully treated, the practice is permissible provided equivalent 
    treatment occurs before the waste is ultimately discharged. Fifth, this 
    option of demonstrating equivalent treatment across a treatment system 
    is not available for Class I nonhazardous deep well injection systems 
    because such units are permanent disposal rather than treatment units. 
    976 F.2d at 24-6.
        These portions of the opinion are addressed in various sections of 
    today's rule.
        The Agency is also addressing the issue of equivalent treatment by 
    Clean Water Act treatment systems managing de-characterized wastes in 
    impoundments by promulgating treatment standards and related 
    requirements that would be used to measure this so-called end-of-pipe 
    equivalence. Finally, EPA is implementing the court's mandate with 
    respect to Class I nonhazardous injection wells by requiring treatment 
    of underlying hazardous constituents in ignitable, and corrosive 
    characteristic wastes being injected into such wells, and prohibiting 
    dilution as a means of achieving those standards.
        Responses to the comments on EPA's reading of the court's opinion 
    are found in the Response to Comment Background Document which is part 
    of the administrative record for this rule. In general, however, the 
    Agency adheres to the reading set out in the proposed rule's preamble 
    at 60 FR 11706-11708.
        EPA is also amending the treatment standards for reactive wastes 
    (other than reactive sulfide and cyanide reactive wastes) so that 
    treatment addresses both the property of reactivity and the threat 
    posed by disposal of underlying hazardous constituents in these wastes 
    (with an exception for ordnance and other explosives which are the 
    subject of an emergency response, as explained in the next paragraph). 
    The Agency is taking this action despite the fact that the court found 
    reactive wastes did not contain sufficient concentrations of hazardous 
    constituents to require any treatment beyond that of removing the 
    characteristic. The Agency believes that it is as likely that reactive 
    wastes contain underlying hazardous constituents at levels that may 
    create a threat as do ignitable and corrosive wastes, and consequently, 
    proposed to regulate reactive wastes in the Phase III proposal. 
    Commenters submitted no data suggesting that reactive wastes do not 
    contain the same types and concentrations of underlying hazardous 
    constituents. Therefore, EPA is promulgating treatment standards for 
    reactive wastes (other than reactive sulfides and cyanides) in this 
    rule that require treatment of all underlying hazardous constituents 
    reasonably expected to be present in the reactive wastes at the point 
    of generation.
        EPA is, however, temporarily deferring application of these amended 
    LDR treatment standards for reactive wastes with respect to unexploded 
    ordnance and other explosive devices which are the subject of an 
    emergency response. An emergency response is an action taken to prevent 
    imminent risk of explosion. (See 40 CFR 264.1(g)(8)
    
    [[Page 15569]]
    setting out circumstances where such responses are exempt from RCRA 
    permitting requirements.) During the development of the proposed 
    Military Munitions Rule: Hazardous Waste Identification and Management; 
    Explosives Emergencies; Redefinition of On-site proposed rule (60 FR 
    56468, November 8, 1995), the Department of Defense, the military 
    services, and other Federal agencies raised concerns that LDR 
    requirements requiring treatment of underlying hazardous constituents 
    might impede the most effective emergency responses involving these 
    materials. If a responding team had to determine LDR applicability 
    before deactivating an explosive subject to an emergency response, the 
    response could be significantly delayed or complicated. Furthermore, 
    concern about LDR applicability might discourage the team from 
    responding at all. This discussion serves as EPA's initial response to 
    these comments.
        EPA agrees that the primary goal in emergency responses to 
    explosives is the safe and prompt elimination of immediate threats to 
    human life and property, and the Agency would be concerned if LDR or 
    other regulatory requirements complicated these responses. The issue is 
    too important and potentially complicated to resolve in today's rule. 
    Therefore, EPA is temporarily deferring final action while it considers 
    this issue further.
        In deferring action for this limited class of reactive wastes, EPA 
    notes that emergency responses present issues different from routine 
    management of reactive wastes, where there is no competing 
    consideration of need for immediate action to prevent an imminent 
    threat. In non-emergency response management situations, as discussed 
    earlier, the Agency believes these wastes can be fully treated to 
    minimize both short and long-term threats posed by land disposal of 
    wastes.1 EPA also is amending the treatment standards for wastes 
    exhibiting the toxicity characteristic to include standards for 
    underlying hazardous constituents.
    
        \1\ EPA also notes that it is not reopening the issue of open 
    burning/open detonation of reactive wastes. In 1986, EPA determined 
    that such activities are not a form of land disposal. See 51 FR at 
    40580 (Nov. 7, 1986).
    ---------------------------------------------------------------------------
    
        Toxic wastes can also contain underlying hazardous constituents in 
    the same potentially harmful concentrations as ICR wastes. 60 FR at 
    11706. Today's final rule consequently conforms standards for toxic 
    characteristic hazardous wastes to assure treatment of underlying 
    hazardous constituents as well, when such constituents are present at 
    levels exceeding the minimize threat level (as established either by 
    the current technology-based standards or, if risk-based levels are 
    established, exceeding a risk-based level.) Thus, the prohibitions and 
    standards in today's rule will apply to ignitable, corrosive, reactive 
    and toxic characteristic wastes, as just discussed.
    
    II. Miscellaneous Issues for Which EPA Is Not Finalizing an Approach in 
    This Final Rule
    
    A. Treatment Standards for Organobromine Wastes
    
        Organobromine wastes are not yet listed as hazardous. EPA 
    anticipates making a final listing determination in a future 
    rulemaking.
        Although EPA proposed treatment standards for organobromine wastes, 
    it clearly would be putting the cart before the horse to promulgate 
    treatment standards in advance of a determination of whether the wastes 
    are hazardous. The Agency intends to establish treatment standards for 
    organobromine wastes should these wastes are listed in the future.
    
    B. Potential Prohibition of Nonamenable Wastes From Land-Based 
    Biological Treatment Systems
    
        The proposed rule contained an extensive discussion of whether 
    certain wastes should be prohibited from placement in biological 
    treatment surface impoundments because they are not amenable to 
    biological treatment. To allow more time to gather comments, the Agency 
    has decided to address this issue in the LDR Phase IV rule, which was 
    proposed on August 22, 1995 (60 FR 43654) and is scheduled to be 
    finalized in June of 1996.
    
    C. Certain Sections of Completing Universal Treatment Standards
    
        The LDR Phase III proposed rule included a section on the 
    completion of universal treatment standards (60 FR at 11727, March 2, 
    1995). Possible nonwastewater universal treatment standards (UTS) for 
    eleven constituents were discussed in the proposal, and comments and 
    data were solicited. In general, commenters felt more data should be 
    gathered before EPA proposes nonwastewater standards for these 
    constituents, and EPA agrees. EPA had also solicited comment and data 
    on extending certain universal treatment standards to fill gaps in the 
    Sec. 268.40 table of universal treatment standards where ``NA'' 
    appeared for either the wastewater or nonwastewater form of a regulated 
    hazardous constituent. Commenters were opposed to this, stating that it 
    would be arbitrary to add a standard to a waste code where before there 
    was none without supporting data. The Agency again agrees. Therefore, 
    EPA is not taking final action at this time.
    
    D. Prohibition of Hazardous Waste as Fill Material
    
        EPA proposed to prohibit use of hazardous waste as fill material. 
    60 FR at 11732. Because issues raised in the proposal are related to 
    those in a number of other pending rulemakings, including the Hazardous 
    Waste Identification Rule, and the proposed rule relating to land-based 
    uses of hazardous waste K061 (59 FR 67256 (Dec. 29, 1994)), EPA is not 
    taking final action on the proposal at this time.
    
    E. Point of Generation
    
        The Agency discussed possible changes that could be made to the 
    ``point of generation''--or point at which LDR requirements attach to a 
    hazardous waste (see 60 FR 11717, March 2, 1995). The Agency is still 
    considering the options discussed in the proposal and potentially other 
    options not discussed. The Agency will reopen the point of generation 
    issue for further comment, and is intending to finalize an option in a 
    future rulemaking.
    
    F. Prohibition on Using Iron Filings to Stabilize Spent Foundry Sand
    
        The Agency proposed designating the practice of adding iron dust/
    filings to spent foundry sand as impermissible dilution (60 FR 11731, 
    March 2, 1995). The Agency is gathering data on the stability of the 
    chemical bond formed between the iron and lead in the spent foundry 
    sand. After the Agency analyzes these data, as well as further studies 
    the public comments on this issue, it may take final action on the 
    proposal.
    
    III. End-of-Pipe Equivalence: Treatment Standards for Clean Water Act 
    (CWA) and CWA-Equivalent Wastewater Treatment Systems
    
    A. Types of Facilities to Which Treatment Standards Apply
    
        As explained above, the D.C. Circuit established a standard of so-
    called end-of-pipe equivalence, allowing CWA treatment systems with 
    surface impoundments to dilute characteristic wastes before land 
    disposal in those impoundments without violating LDR requirements, 
    provided the treatment system destroys, immobilizes, or removes an 
    equivalent amount of hazardous constituent as if the characteristic 
    waste were treated separately to meet RCRA standards. EPA
    
    [[Page 15570]]
    is establishing in this rule the treatment standards that must be 
    satisfied in order to demonstrate that equivalent treatment is 
    occurring.
        These treatment standards apply to the following types of 
    facilities: (1) facilities treating formerly characteristic wastes in 
    surface impoundments whose ultimate discharge is subject to regulation 
    under either section 402 or 307 of the CWA. The rule thus encompasses 
    both direct dischargers (facilities discharging to navigable waters) 
    and indirect dischargers (those discharging to POTWs); and, (2) 
    permitted and unpermitted zero dischargers engaging in treatment that 
    is equivalent to that of the CWA-regulated facilities (see 40 CFR 
    268.37(a) defining CWA-equivalent treatment), including facilities 
    treating formerly characteristic wastes in tanks prior to release on 
    the land for such purposes as irrigation or land treatment.
        EPA also wishes to make clear the types of wastewater management 
    situations to which these standards do not apply. First, the standards 
    do not apply to facilities that discharge to navigable waters or POTWs 
    and that manage decharacterized wastes in treatment systems without 
    surface impoundments. Consequently, if a facility generates a 
    characteristic waste, dilutes it so that it no longer exhibits a 
    characteristic, and then treats the waste in tanks before ultimate 
    discharge to a navigable water or a POTW, this rule does not apply. 
    There is no land disposal of a prohibited waste occurring and 
    consequently no RCRA requirement that the characteristic waste be 
    pretreated. Applicable CWA limitations and standards would, of course, 
    continue to apply (as would a one-time recordkeeping requirement under 
    RCRA (see Sec. 268.9).
        Second, the standards do not apply in situations where RCRA 
    hazardous waste (subtitle C) impoundments are used. The statute already 
    sets out the requirements for subtitle C impoundments receiving wastes 
    which may not yet have met a treatment standard. RCRA section 
    3005(j)(11). These requirements are not altered by the Third Third 
    opinion. 976 F. 2d at 24 n. 10.
        Finally, in response to comment, EPA has determined that the end-
    of-pipe treatment standards should not apply to stormwater 
    impoundments. Stormwater impoundments are used by treatment facilities 
    to catch stormwater during rain events, because their biological 
    treatment systems cannot adequately handle such sudden, large volumes 
    of water. At some treatment facilities, however, because they have a 
    combined wastewater system, stormwater impoundments also receive 
    process water containing decharacterized wastes.
        The Agency agrees with commenters who stated that stormwater 
    impoundments are necessary to maintain the efficacy of biological 
    treatment units. In addition, such impoundments are empty most of the 
    time because they are designed for emergency rain events. In the Third 
    Third opinion, the court focused on wastewater treatment surface 
    impoundments. It seems likely that stormwater impoundments were outside 
    the court's consideration. Furthermore, imposing treatment standards on 
    such impoundments could require treatment of the stormwater/
    decharacterized waste before it could permissibly go into the 
    impoundment, not a practical alternative during a major storm event. 
    Alternatively, imposing LDR treatment standards might require the 
    facility to replace its combined wastewater system, which would be a 
    major disruption to most of these facilities and hardly seems justified 
    when stormwater impoundments are used only on an emergency basis. These 
    are the very types of disruptions that the integration clause in RCRA 
    1006(b) is intended to prevent. Consequently, EPA is indicating that 
    today's rule does not apply to stormwater impoundments.
    
    B. End-of-Pipe Treatment Standards
    
        The treatment standards that EPA is promulgating for characteristic 
    wastewaters are found in the table of LDR treatment standards at 40 CFR 
    268.40 and 268.48. As explained more fully in the following section, 
    these treatment standards generally adopt the limitations or standards 
    that apply to the facility's discharge as the RCRA treatment standards. 
    The reason EPA is taking this approach is that the CWA industry 
    category or case-by-case industrial POTW limitations and standards 
    represent specific determinations of what Best Available Treatment 
    (BAT) technology is capable of achieving for that plant's wastewater, 
    or, in the case of Water Quality Criteria-based limitations, what an 
    appropriate limit is based on BAT treatment plus risk-based 
    considerations. In the event a hazardous constituent present in the 
    wastewater at point of generation of the original characteristic 
    hazardous waste is not already regulated pursuant to a CWA limitation 
    or standard, the RCRA Universal Treatment Standard for that constituent 
    would apply.
        These treatment standards may be met at the CWA point of 
    compliance, typically the point the wastewater is discharged to a 
    navigable water or a POTW. For CWA-equivalent facilities, the treatment 
    standards must be met at the point where the wastewater is sprayed onto 
    the land in irrigation (or similar) activities, or injected into a non-
    Class I injection well. This accords with the equivalence standard 
    established by the court: ``hazardous constituents are [to be] removed 
    from the waste before it enters the environment.'' 976 F. 2d at 24; see 
    also id. at 23 and n. 8. Most commenters likewise agreed with an end-
    of-pipe measuring point. Indeed, requiring full treatment before 
    ultimate discharge could destroy the very accommodation with the CWA 
    regime that the court thought critical. See 60 FR at 13677 (Aug. 22, 
    1995).
        However, EPA also agrees with commenters that there is no reason to 
    impede individual facilities from choosing an alternative point of 
    compliance (i.e. other than end-of-pipe) provided the facility can 
    demonstrate that the prohibited waste (the decharacterized portion of 
    the combined effluent) has been treated by means other than dilution to 
    remove an equivalent mass of hazardous constituents. This is 
    specifically consistent with the principle announced in the 
    Administration's report on ``Reinventing Environmental Regulation'' to 
    ``provid[e] maximum flexibility in the means of achieving our 
    environmental goals, but requiring accountability for the results''. 
    Consequently, the Agency is allowing a facility to designate any 
    compliance point downstream of treatment that destroys, immobilizes, or 
    removes hazardous constituents as the point for demonstrating that 
    equivalent treatment occurs. This point can, but need not be, the NPDES 
    or pretreatment point of compliance. Examples of alternative points of 
    compliance that would be permissible (assuming the treatment standard 
    is being satisfied) would be prior to initial placement in an 
    impoundment, or after treatment in an impoundment but before final 
    discharge.
        The Agency also agrees with commenters that there can be 
    alternative points of compliance for different underlying hazardous 
    constituents. Again, the reason is to allow flexibility of compliance 
    alternatives when a facility can demonstrate that it is destroying, 
    immobilizing, or removing an equivalent mass of hazardous constituents 
    through wastewater treatment as would be achieved by segregating the 
    characteristic wastestream for separate RCRA treatment. Thus, if a 
    facility generated a
    
    [[Page 15571]]
    characteristic waste containing metal and organic underlying hazardous 
    constituents and the waste was treated sequentially by means not 
    involving impermissible dilution, there could be different compliance 
    points for the metal and organic hazardous constituents.
        EPA notes, however, that if alternative points of compliance are 
    utilized, enforcement would normally be pursuant to RCRA, not the Clean 
    Water Act. This is by necessity, since CWA permits (or, for indirect 
    dischargers, control mechanisms) would not normally apply to effluent 
    quality before final discharge. See further discussion on means of 
    implementing today's standards below in this preamble.
    
    C. Why CWA Limitations and Standards Can Also Be RCRA Treatment 
    Standards
    
        As explained above, when a hazardous constituent is already subject 
    to a CWA industry category or Water Quality Criteria-based limitation, 
    or a case-by-case industrial POTW limitation or standard, the Agency 
    believes (and the final rule provides) that the CWA limitations and 
    standards satisfy RCRA section 3004(m) requirements and consequently 
    become the RCRA treatment standard for purposes of demonstrating 
    equivalent treatment. EPA believes that this is an obvious and 
    effective means of integrating CWA and RCRA requirements, in accord 
    with the court's objective. 976 F. 2d at 22; RCRA section 1006(b). This 
    approach was generally supported by commenters as a reasonable means of 
    satisfying the court's mandate and the underlying policy of integration 
    of the two statutes.
        Several commenters, however, argued that CWA limitations and 
    standards could not be equivalent to RCRA because such standards can 
    reflect (among other things) ``the cost of achieving such effluent 
    reduction'', and ``the age of equipment and facilities involved''. CWA 
    section 304(b)(2)(B) (factors to be considered in determining Best 
    Available Technology). EPA disagrees. While it is true that technology-
    based standards developed to address toxic pollutants from various 
    industrial categories are developed after consideration of levels that 
    can be achieved through application of the best available technology 
    economically achievable, the CWA limitations and standards nevertheless 
    represent the best evaluation of what technically advanced wastewater 
    treatment is capable of achieving for a particular industry's (or, in 
    some cases, particular plant's) wastewater. Although there is no 
    requirement that a particular treatment technology must be used to 
    achieve the facility's limits, it is expected that plants utilizing BAT 
    will have treated their effluent so that there are substantial 
    reductions in concentration and mass of hazardous constituents. As the 
    Agency has stated many times, EPA believes that section 3004(m) is 
    satisfied by treatment that substantially destroys, immobilizes, and 
    removes the hazardous constituents that are present in the waste, 
    notwithstanding that minor amounts of hazardous constituents remain 
    after treatment. Put another way, the statute does not require that 
    every conceivable threat posed by land disposal be eliminated by 
    treatment. 55 FR at 6641 and n. 1 (Feb. 26, 1990); 56 FR at 12355 
    (March 25, 1991); 57 FR 37259 (August 18, 1992); 55 FR at 22596 (June 
    1, 1990). In fact, the legislative history states explicitly that the 
    treatment standards are not to be technology forcing, but rather are to 
    utilize the available effective treatment technologies. 130 Cong. Rec. 
    S. 1978 (daily ed. July 25, 1984) (statement of Sen. Chaffee); 56 FR at 
    12355. That is precisely what EPA has done here.
        Second, with specific regard to use of CWA limitations, EPA notes 
    that virtually all of the current LDR treatment standards for 
    wastewaters are already drawn from CWA limitations and standards. See 
    55 FR at 22601 (wastewater standards for U and P wastes and F039, which 
    essentially became the universal treatment standards, were transferred 
    from treatment data from CWA programs), and see also the Final BDAT 
    Background Document for U and P Wastes and Multi-Source Leachate (F039) 
    Volume C (documenting that most of existing RCRA wastewater standards 
    were transferred from CWA limitations and standards). Moreover, the 
    technologies that are often used to achieve CWA limitations and 
    standards are, in most cases, the same technologies upon which the RCRA 
    Universal Treatment Standards are based. As EPA has already stated, 
    ``because most treatment technologies cannot be so precisely calibrated 
    as to achieve, for example, 3.5 ppm rather than 2.7 ppm, the likely 
    result is that the same amount of treatment will occur.'' 59 FR at 
    47989 (Sept. 19, 1994). Since frequently the same technologies are used 
    to treat wastewaters, EPA expects the degree of treatment to be 
    comparable.
        EPA also emphasizes that RCRA section 1006(b) requires EPA (among 
    other things) to integrate provisions of RCRA and the CWA when 
    implementing RCRA, and to avoid duplication to the maximum extent 
    possible with CWA requirements. The Agency feels it is accomplishing 
    this requirement by allowing a constituent-specific, CWA treatment 
    standard to satisfy RCRA 3004(m). The Agency reiterates that a 
    technology-based CWA limitation or standard for a hazardous constituent 
    satisfies RCRA because such a limitation or standard directly reflects 
    the capability of BAT technologies to treat a specific industry's or 
    facility's wastewater, whereas the RCRA UTS for wastewaters were 
    developed by transferring performance data from various industries, and 
    thus EPA need not make that same transfer when industry-specific (or 
    plant-specific) wastewater treatment data is available.
        A water-quality based limitation would also satisfy RCRA section 
    3004(m). A CWA water quality-based limitation must be at least as 
    stringent as the limitations required to implement an existing 
    technology-based standard. (See CWA section 301(b)(1)(c).) Even where 
    there is no existing BAT limitation for a toxic or nonconventional 
    pollutant, a permit writer must determine whether BAT would be more 
    stringent than the applicable water quality-based limitation, and 
    again, must apply the more stringent of the two potential limitations. 
    (40 CFR 125.3(c)(2).)
        If a facility has received a Fundamentally Different Factors (FDF) 
    variance, the limitations established by that variance also satisfy 
    RCRA requirements. Limitations established by the FDF variance process 
    are technology-based standards reflecting facility-specific 
    circumstances, and hence can appropriately be viewed as BDAT as well, 
    just as with RCRA treatability variance standards. See 51 FR at 40605 
    (Nov. 7, 1986).
        EPA also believes that there are adequate constraints in the CWA 
    implementing rules to prevent these end-of-pipe standards from being 
    achieved by means of simple dilution. First, many of the effluent 
    limitation guidelines and standards regulate the mass of pollutants 
    discharged, and thus directly regulate not only the concentration of 
    pollutant discharged but the degree of wastewater flow as well. Even 
    where rules are concentration-based, NPDES permit writers can set 
    requirements which preclude excessive water use, and EPA has so 
    instructed permit writers. (See 58 FR 66151, December 17, 1993, 
    encouraging permit writers to estimate reasonable rate of flow per 
    facility and factor that flow limit into the permit.) These permit 
    conditions can take the form of best management practices,
    
    [[Page 15572]]
    explicit mass limitations, and conditions on internal waste streams. 40 
    CFR 122.44(k); 122.45 (f), (g) and (h).
        Indirect dischargers are also subject to specific CWA dilution 
    rules in both the general pretreatment rules and the Combined 
    Wastestream Formula (as well as through many of the categorical 
    standards). 40 CFR 403.6 (d) and (e). Many of the guidelines and 
    standards also preclude addition of stormwater runoff to process 
    wastewater to preclude achieving treatment requirements by means of 
    dilution. The Agency is accordingly of the view that end-of-pipe 
    equivalence would be achieved by treatment that removes, immobilizes, 
    or destroys hazardous constituents, and therefore we have determined 
    the treatment satisfies the requirements of RCRA section 3004(m).
        EPA emphasizes, however, that it is not addressing the issue of 
    whether cross-media transfers of hazardous constituents become so 
    extensive as to invalidate the wastewater treatment function of a land-
    based unit. This is the subject of the pending Phase IV proposed rule 
    (60 FR at 43654 (August 22, 1995)), and will be addressed as part of 
    that proceeding.
    
    D. When CWA Limitations and Standards Become the RCRA Standards
    
        Today's rule establishes the following principles:
    1. Direct Dischargers
        A CWA limitation becomes the RCRA treatment standard as well in the 
    following situations: (a) where there is a categorical BAT or NSPS 
    limitation for the underlying hazardous constituent; (b) where there is 
    a facility-specific limitation for the underlying hazardous constituent 
    pursuant to 40 CFR 125.3 (c)(2) and (d)(3); (c) where there is a Water 
    Quality-based limitation established pursuant to 40 CFR 122.44(d); or 
    (d) where the facility has received a Fundamentally Different Factors 
    variance establishing an alternative limitation pursuant to 40 CFR Part 
    125 subpart D.
    2. Indirect Dischargers
        A Clean Water Act pretreatment standard becomes the RCRA treatment 
    standard as well in the following circumstances: (a) where there is a 
    categorical PSES or PSNS for a particular hazardous constituent; and, 
    (b) where POTWs have developed local limits, in addition to categorical 
    standards, to prevent pass through and interference and apply them to 
    indirect dischargers.
        EPA proposed that if pretreatment standards reflected a finding 
    that a particular hazardous constituent will not pass through to 
    navigable waters because of efficacious treatment by the POTW, that 
    standard would also satisfy RCRA. The reason is that there will be 
    full-scale treatment of the hazardous constituent before its final 
    release into the environment. Such full-scale treatment satisfies the 
    court's equivalency test. 60 FR at 11711. EPA is adopting this 
    provision in today's rule for these reasons.
        The Agency also proposed that pretreatment standards based on 
    interference with POTW operations would not be considered to satisfy 
    RCRA. Id. EPA is adopting this position in the final rule. The reason 
    is that interference findings reflect the effect the pollutant may have 
    on overall POTW treatment, not necessarily treatment of the particular 
    constituent. Because the relationship of an interference-based standard 
    with treatment of a particular hazardous constituent is tenuous, EPA 
    does not believe that such a standard can be said to be equivalent to 
    RCRA treatment. Several commenters disagreed with this reasoning, but 
    provided no empirical information calling the Agency's conclusion into 
    question. EPA is consequently adopting this provision as proposed.
    3. Zero Dischargers Performing CWA-Equivalent Treatment
        In the May 24, 1993 emergency rule, EPA established the principle 
    that zero discharge facilities performing CWA-equivalent treatment on 
    decharacterized wastewaters would be subject to the rules for direct 
    dischargers, and thus would retain the ability to use surface 
    impoundments as part of the treatment process for decharacterized 
    wastes provided equivalent treatment occurs. 58 FR at 29863-29864. The 
    reason is that these facilities can be performing wastewater treatment 
    identical to, or more stringent than, that required of direct 
    dischargers, and thus the same policy of integrating RCRA and the CWA 
    should apply to such facilities. Id. 
        EPA is consequently also applying today's rules on equivalency to 
    zero dischargers performing CWA-equivalent treatment, including tank-
    based systems that ultimately land dispose rather than discharge 
    treated effluent. ``CWA-equivalent treatment'' is defined in 268.37(a) 
    to mean ``biological treatment for organics, alkaline chlorination or 
    ferrous sulfate precipitation/sedimentation for metals, reduction of 
    hexavalent chromium, or other treatment technology that can be 
    demonstrated to perform equally or greater than these technologies''.
    
    E. Implementation
    
    1. Where Permits Contain Standards for Hazardous Constituents
        If a direct discharger subject to the rule (i.e. generating a 
    characteristic waste containing underlying hazardous constituents at 
    concentrations exceeding the treatment standard at the point the waste 
    is generated, and is treating those decharacterized wastes in surface 
    impoundments) has an NPDES permit containing a limitation for that 
    hazardous constituent based on BAT, NSPS, BPJ, or a water quality 
    standard, then there are no independent RCRA requirements beyond 
    documenting in the facility's records that this is the facility's mode 
    of compliance.
        EPA notes further that if the Agency (or authorized State), as part 
    of the CWA decisionmaking process for setting the limitations, 
    affirmatively decided that such hazardous constituents need not be 
    regulated due to low toxicity, low bioavailability or other 
    environmental factors and that fact is reflected in the rulemaking 
    record, permit or permit record, no additional RCRA standards would 
    apply. If the rulemaking or permit and permit record do not contain 
    such a finding, the permitting authority should reexamine the NPDES 
    permit upon reissuance in order to clarify whether such hazardous 
    constituents need not be regulated. During the time between the date 
    this rule becomes effective and the date the permit is reissued, 
    however, the RCRA Universal Treatment Standards for those constituents 
    must be met.
        In addition, if EPA (or an authorized State) affirmatively decided 
    either in the rulemaking or in the permitting process that a particular 
    hazardous constituent is controlled through controls on an indicator 
    pollutant, then again, no additional RCRA standards would apply. For 
    this purpose, however, the Agency would only accept as a valid 
    indicator situations where a toxic pollutant parameter is used as an 
    indicator for another toxic pollutant. The Agency does not believe that 
    use of conventional pollutants (such as BOD or COD) as indicators for 
    toxic constituents guarantees the type of equivalent treatment of 
    hazardous constituents, which EPA feels is necessary to implement the 
    equivalence requirement. 976 F. 2d at 23 n. 8.2
    
        \2\ In making this statement, EPA is of course not calling into 
    question the use of conventional pollutants as valid indicators to 
    satisfy Clean Water Act requirements. The language in the text is 
    directed solely at implementing the court's mandate for purposes of 
    RCRA.

    2. Where Permits Do Not Contain a Limitation for a Hazardous 
    Constituent
        If the CWA permit either does not contain a limitation for the 
    pollutant or does not regulate the pollutant through an indicator, or 
    in cases when this rule becomes effective before the reissuance of a 
    facility's permit, the RCRA universal treatment standards would apply 
    as they do for any other RCRA hazardous wastestream. In this situation, 
    the owner or operator of a facility has several choices. The owner/
    operator could do nothing, in which case the hazardous constituent 
    would be subject to the UTS. These standards would be implemented by 
    rule, and thus would not be embodied in a CWA permit. Enforcement 
    consequently would be solely under RCRA. As noted earlier, the point of 
    compliance could, but need not be, at the end-of-pipe point of 
    discharge.
        In the alternative, a facility could seek amendment of its NPDES 
    permit pursuant to Sec. 122.62(a)(3), requesting that the applicable 
    permitting authority modify the permit at reissuance, or sooner, to add 
    limits for the underlying hazardous constituents reflecting BAT for 
    that pollutant at the facility.\3\ Assuming proper design and operation 
    of the wastewater treatment technology, a permit writer in such a case 
    could modify the permit to add a limitation for the pollutant based on 
    Best Professional Judgement reflecting actual BAT treatment (40 CFR 
    125.3(c)). Modification requests would be processed pursuant to the 
    procedures found at Sec. 124.5. The modified permit limitation would be 
    a CWA requirement and enforceable solely under that statute, but would 
    be deemed by the Agency to satisfy RCRA 3004(m), so that meeting UTS 
    per se would not be required.
    
        \3\ EPA is interpreting the language in Sec. 122.62(a)(2) to 
    indicate that the D.C. Circuit's opinion in the Third Third case is 
    new information warranting reopening a permit.
    ---------------------------------------------------------------------------
    
        A final alternative is for the facility to seek a RCRA treatability 
    variance. EPA is amending the grounds for granting such a variance to 
    include situations where a facility is treating decharacterized wastes 
    by treatment identified as BAT or NSPS (New Source Performance 
    Standards), the technology is designed and operated properly, but is 
    not achieving the UTS (see Sec. 268.44(a)).
    3. Indirect Dischargers
        The same alternatives exist for indirect dischargers. If an 
    underlying hazardous constituent is regulated by a categorical PSES, 
    PSNS, or by a local limit in a control mechanism reflecting PSES or 
    PSNS--level treatment, then that standard satisfies both RCRA and the 
    CWA. In addition, if there is no pretreatment standard (i.e., PSES/
    PSNS) for an underlying hazardous constituent, because the Agency 
    determined that there was no pass through, then section 3004(m) is 
    satisfied and the RCRA standard for that underlying hazardous 
    constituents does not apply.
        If an underlying hazardous constituent is not regulated nationally 
    by a PSES or PSNS, or by a local limit, it becomes subject to the UTS 
    for that constituent. That UTS would be enforced as a RCRA standard. 
    However, in cases where an underlying hazardous constituent is not 
    already subject to categorical PSES, categorical PSNS, or to a local 
    limit in a control mechanism reflecting PSES or PSNS-level treatment, 
    water quality, or pass through, the control mechanism between the 
    indirect discharger and the applicable control authority would have to 
    be modified in order to avoid application of the UTS by rule. EPA is 
    amending Sec. 403.5(c)(1) and Sec. 403.5(c)(2) of the pretreatment 
    rules to specifically authorize control authorities to make such 
    determinations.
        The final option is for a facility to obtain a RCRA treatability 
    variance. Thus, the amendment to the treatability variance rules also 
    applies to indirect dischargers properly operating technology 
    identified as the basis for their PSES or their PSNS standard.
    4. Zero Dischargers Performing CWA-Equivalent Treatment
        The implementation options for zero dischargers performing CWA-
    equivalent treatment are similar. Some of these facilities may have CWA 
    permits authorizing specified levels of discharge. If these permit 
    limitations apply to underlying hazardous constituents present in the 
    RCRA-prohibited portion of the discharge, the CWA permit limit 
    satisfies RCRA as well. The facility also could seek to amend the CWA 
    permit to add limitations for the hazardous constituent. Enforcement 
    then would be exclusively pursuant to the CWA.
        If the zero discharger has no CWA permit, or the permit does not 
    contain limitations for underlying hazardous constituents and is not 
    amended to do so, then the facility would have to meet the RCRA UTS or 
    an alternative standard established by treatability variance either at 
    the point of discharge 4 or at an earlier point of its choosing 
    (assuming, of course, that a valid demonstration of bona fide treatment 
    can be made at an earlier point).
    
        \4\ The point of compliance for a zero discharger choosing the 
    point of discharge as a compliance point would be at the point of 
    ultimate disposal. For those zero dischargers who discharge to a dry 
    river bed (common in the western U.S.) not considered a ``water of 
    the U.S.'' under the CWA, the point of compliance would be at the 
    end-of-pipe. For those zero dischargers who spray irrigate, or 
    otherwise place the wastewaters on the land after treatment in the 
    surface impoundment, the point of compliance would be at the point 
    just prior to the land placement. Furthermore, zero dischargers 
    treating wastewaters in a tank system followed by spray irrigation 
    or another form of land placement are also subject to this rule. For 
    those zero dischargers who use evaporation ponds, the point of 
    compliance is before the wastewater enters the surface impoundment, 
    as this is the ultimate disposal point.
    ---------------------------------------------------------------------------
    
    5. Implementation When CWA Standards and Limitations Will Not Be the 
    Exclusive Standard
        If the facility treats to UTS and does not modify its CWA permit or 
    control mechanism to include a CWA standard/limitation for an 
    underlying hazardous constituent, EPA is finalizing minimal 
    recordkeeping requirements, under RCRA authority. Generators can use 
    their knowledge to identify the underlying hazardous constituents 
    reasonably expected to be present at the point of generation of the 
    ICRT wastes which are not covered by a CWA limitation or standard and 
    hence must be treated to meet UTS (assuming no permit modification). 
    EPA is requiring that this information be kept on-site in files at the 
    facility. The facility will then monitor compliance with the UTS 
    standard for each of these constituents at the point of ultimate 
    discharge or alternative compliance point, on a quarterly basis, and 
    results of this monitoring must be kept in the facility's on-site 
    files. An exceedence of the RCRA UTS standard must be documented in the 
    facility's on site records.
        These same requirements apply to facilities without NPDES permits 
    documenting compliance as zero dischargers with CWA-equivalent 
    treatment who are affected by this rule. The absence of a permit 
    necessitates some alternative means of documenting compliance, and the 
    scheme outlined above seems to be the least burdensome scheme which 
    would still provide a reasonable means of enforcing this rule.
    6. RCRA Controls Over Point Source Discharges and Domestic Sewage
        Both RCRA and the implementing regulations provide that point 
    source discharges and domestic sewage (including mixtures of domestic 
    sewage with other wastes) are not subject to
    
    [[Page 15574]]
    RCRA subtitle C jurisdiction. RCRA section 1004(27) and Sec. 261.4(a) 
    (1) and (2). Some commenters questioned whether by allowing CWA 
    limitations and standards to satisfy the RCRA treatment standard 
    requirement, EPA were somehow imposing RCRA controls where it lacks 
    authority to do so.
        This is not the case. EPA is creating here a mechanism for 
    evaluating whether RCRA-equivalent treatment has occurred for purposes 
    of determining whether surface impoundments (i.e. RCRA land disposal 
    units) can permissibly be used as part of that treatment process. 976 
    F. 2d at 22-24. The effect, for RCRA purposes, of failing to satisfy 
    the limitations or standards is that the facility has engaged in 
    illegal land disposal by virtue of not performing equivalent treatment. 
    Id. Thus, the effect of the rule is on activity upstream of the 
    discharge point, and these activities are within RCRA's jurisdictional 
    purview.
    7. Applicability to the Pulp and Paper Industry
        The concerns about integration of CWA and RCRA standards are 
    particularly acute with respect to the pulp and paper industry. EPA is 
    at a critical stage in developing comprehensive multi-media rules for 
    this industry (to control both hazardous air emissions and wastewater 
    discharges). These rules were proposed at 58 FR 66078 (Dec. 17, 1993) 
    and are slated for promulgation by mid-1996. The rules should 
    fundamentally affect (for the better) the types of wastewaters managed 
    at pulp and paper facilities and the potential releases of hazardous 
    constituents from such wastes. The Agency believes that it would be 
    putting the cart before the horse, and would fail to properly 
    integrating RCRA with the CWA (and potentially CAA in this case) by 
    proceeding with implementation of the court's decision for this 
    industry in advance of completion of this rulemaking. Cf. Edison 
    Electric Inst. v. EPA, 2 F. 3d 438, 453 (D.C. Cir. 1993) noting when 
    temporary deferrals of action to allow better integration of 
    overlapping statutes is permissible. The Agency will revisit the 
    question of how to implement the court's decision for the pulp and 
    paper industry upon completion of the existing multi-media rulemaking.
    
    IV. Treatment Standards for Class I Nonhazardous Injection Wells and 
    Response to Comments
    
    A. Introduction
    
        Generally, Class I nonhazardous injection well owners/operators 
    injecting decharacterized ICRT wastes do not substantially treat their 
    waste beyond removing the characteristic by aggregating and diluting 
    wastestreams, plus filtering of solids in order to facilitate 
    injection. There are as many as 100 such nonhazardous facilities in 
    addition to the approximately 54 hazardous facilities injecting ICRT 
    wastes. As discussed in the Phase III proposed rule, EPA estimates that 
    the average flow of a ``typical'' Class I nonhazardous well is 107,000 
    gallons/day. Typically, the volume of hazardous wastes comprises 25% or 
    less of the aggregated injected wastestream.
        In the Third rule, EPA proposed that characteristic wastes were not 
    prohibited from injection into these deep wells provided they no longer 
    exhibited a characteristic at the point they are injected.e. land 
    disposed. 60 JR at 11704-11705. The D.C. Circuit rejected this portion 
    of the rule, holding, in EPA's reading of the opinion, that the 
    statutory requirements could not be satisfied absent treatment that 
    addressed both short term and long term threats posed by land disposal 
    of the waste, and hence that hazardous constituents in the waste had to 
    be destroyed, removed or immobilized before injection, not merely 
    diluted. 60 JR at 11706-11708. EPA is implementing that mandate in this 
    rule. (However, EPA reiterates, as it did at proposal, that EPA is 
    taking this action to implement the court's mandate, not because it is 
    an environmental priority, or prudent use of the Agency's or the 
    regulated community's resources. The Administration is in fact pursuing 
    a legislative change which would restore EPA's original policy 
    determination reflected in the 1990 Third rule.)
        The effect of today's final rule is to prohibit the land disposal 
    of characteristic waste streams at the point they are generated. If 
    those wastes contain underlying hazardous constituents at levels 
    exceeding the Universal Treatment Standards and (as explained further 
    below) at levels and volumes greater than designated de minims amounts, 
    those constituents would have to be destroyed, removed, or immobilized 
    before the waste is injected. This could be accomplished either by 
    segregating the characteristic portion of the injectate for treatment, 
    or by treating the commingled injectate before disposal (i.e. before 
    injection). The rule further provides that if a facility removes an 
    equivalent mass of the hazardous constituent through source reduction, 
    or waste treatment, that the treatment standard is satisfied. The 
    final, alternative means of compliance is for the unit to have received 
    a no-migration determination.
        A number of commenters believed that aggregation or dilution of 
    wastes to remove the hazardous characteristic of the waste stream prior 
    to injection was sufficient and that the requirement to treat 
    underlying constituents was legally unnecessary and onerous. EPA's 
    reading of the Third Third opinion and section 3004(m) is that 
    treatment that destroys, immobilizes, or removes hazardous constituents 
    is required, and that this requirement is not satisfied merely by 
    dilution. The statutory findings of the inherent uncertainty of land 
    disposal of hazardous wastes, the propensity to bioaccumulate these 
    same constituents, the statutory goals of waste minimization and proper 
    waste management, plus the legislative history documenting 
    Congressional intent not to permit treatment by dilution supports the 
    Agency in rejecting these comments. 60 FR at 11706-708. Therefore, the 
    Agency has decided not to allow Class I nonhazardous wells to dilute or 
    aggregate their waste streams in order to fulfill, substitute, or avoid 
    treatment levels or methods established in the LDRs. See the dilution 
    prohibition added in Sec. 148.3 of today's final rule.
        Furthermore, the Agency, as proposed, is expanding the 
    applicability of 40 CFR Part 148 to now require owners/operators of 
    Class I nonhazardous wells to determine whether LDRs apply to their 
    facilities.
        Commenters likewise sharply questioned the Agency's determinations 
    as to when land disposal prohibitions should attach, and state, 
    correctly in the Agency's view, that the opinion did not compel a 
    determination that prohibitions must attach at the initial point of 
    waste generation or when underlying hazardous constituents are present 
    at that point in concentrations exceeding the UTS. EPA is in fact 
    pursuing alternatives on both of these fronts. The Agency proposed 
    alternatives to the strictest point of generation approach, 60 FR at 
    11715-716, and expects to take final action on this proposal well 
    before the effective date of the Phase III prohibitions for Class I 
    non-hazardous UIC wells. The source reduction compliance option in this 
    rule is a related means of dealing with this issue, since it can be 
    conceptualized as allowing the requisite hazardous constituent 
    reductions to be achieved by means other than downstream treatment 
    notwithstanding presence of hazardous constituents above UTS at what is 
    technically point of waste generation.
        With regard to whether presence of hazardous constituents above UTS
    
    [[Page 15575]]
    would be the trigger level for the LDR prohibition, EPA has recently 
    proposed risk-based hazardous constituent concentration levels which 
    would implement the ``minimize threat'' requirement in section 3004(m), 
    and would cap the technology-based treatment standards whenever the 
    technology-based standards are lower (60 FR 66344, December 21, 1995). 
    The de minimis feature of today's rule further addresses situations 
    where EPA believes that prohibitions need not apply due to the low 
    concentrations and volumes of hazardous constituents in the 
    decharacterized portion of the injectate.
    
    B. Compliance Options for Class I Nonhazardous Wells
    
        In the proposed rule, the Agency indicated that facilities could 
    segregate their hazardous wastes, and treat just that volume of the 
    total waste stream to UTS levels in order to conform to the treatment 
    requirement. A number of commenters maintained that the Agency 
    oversimplified this approach and that such segregation was impractical 
    from both a technical and economic standpoint. EPA acknowledges that 
    many facilities may not practically be able to segregate streams. These 
    facilities may utilize of other LDR compliance options as discussed 
    below.
        One option would be to apply for an exemption from treatment 
    standards via the no-migration petition variance. EPA is promulgating a 
    clarifying revision to 40 CFR 148.20 which allows facilities to seek a 
    no-migration variance for their Class I nonhazardous wells, and has 
    long indicated that this compliance option is available (see pp. 25-27, 
    Supplemental Information Report prepared for the Notice of Data 
    Availability, January 19, 1993, 58 FR 4972). If these facilities 
    demonstrate to EPA that their formerly characteristic wastes (including 
    any hazardous constituents) will not migrate out of the injection zone 
    for 10,000 years, or no longer pose a threat to human health and the 
    environment because the wastes are attenuated, transformed, or 
    immobilized by natural processes, then they may continue to inject 
    without further treatment.
        A significant number of commenters responded to the proposed rule's 
    discussion on the Agency's position on granting no-migration petitions. 
    Comments included that petitions were a too costly option, took too 
    much time to be processed, generic petitions for Class I non-hazardous 
    wells should be granted, and existing no-migration exemptions should 
    not require modification to include Phase III wastes. These comments, 
    among others, will be discussed in detail in the ``Response to 
    Comments'' background document for this rule, but basically many had 
    partial merit.
        First, although the Agency has estimated earlier that the average 
    petition costs an operator $343,000, several individual petition 
    reviews have far exceeded that amount. The Agency will examine the 
    possibility of revising petition cost data in future LDR rules. Second, 
    although a petition may take up to 3 years to process, the Agency (as 
    noted above) indicated as early as 1992 (after the Third Third opinion) 
    that it would begin review of Class I nonhazardous injection well no-
    migration petitions if submitted (58 FR 4972, January 19, 1993). 
    Although time and resource restraints on the Agency are real, the 
    Agency will continue to work with affected Class I operators in order 
    to facilitate the no-migration petition review process. Third, although 
    EPA has established a reasonable knowledge base on the review process 
    for Class I hazardous facilities, it cannot automatically infer that 
    all Class I nonhazardous facilities will successfully make a no-
    migration demonstration. Well site geology, hydrogeology, abandoned 
    well area of review, and the specific characteristics of the injectate 
    and receiving formation are site specific factors which, as a factual 
    matter, must be evaluated individually in order to demonstrate ``to a 
    reasonable degree of certainty'' (RCRA section 3004(g)(5)) that the no 
    migration standard has been satisfied. See Supplemental Report to 
    Notice of Data Availability, January 19, 1993, at 25-26 9. It must be 
    remembered that not every Class I injection well applying for the 
    variance has been able to make the demonstration, and that one salutary 
    effect of the no migration process has been to identify certain (albeit 
    a limited number of) wells that would not be capable of adequately 
    containing injectate over the long term.
        EPA agrees completely with commenters, however, that wells that 
    already have approved no migration exemptions are not affected by the 
    Third Third opinion and thus are not affected by land disposal 
    restrictions affecting decharacterized wastes. (In fact, EPA does not 
    read the proposal to suggest otherwise.) Absent a change in the waste 
    being injected, there is no reason to reopen no migration 
    determinations that have already evaluated the entire injected waste 
    stream. 57 FR at 31963 (July 20, 1992).
        EPA is also promulgating additional means for Class I nonhazardous 
    facilities to comply with the LDR requirements. Revisions to 40 CFR 
    148.1(c)(1) and 148.4 will allow Class I nonhazardous owners and 
    operators to apply for a case-by-case extension of the capacity 
    variance for up to one year (renewable for up to an additional year) in 
    order to acquire or construct alternative treatment capacity. Based on 
    experience, EPA believes that the availability of the case-by-case 
    extension coupled with national capacity variance(s) should allow 
    operators more than adequate time to acquire alternative treatment or 
    complete the no-migration petition process. Two other options include 
    the pollution prevention option and the de minimis volume exclusion.
    
    C. Pollution Prevention Compliance Option
    
        The final rule provides an alternative means of obtaining the 
    reductions in mass loadings of hazardous constituents mandated by the 
    Third Third opinion. Under this alternative, mass reductions can be 
    achieved by removing hazardous constituents from any of the 
    wastestreams that are going to be injected, and these reductions in 
    mass loadings can be accomplished by means of source reduction (i.e. 
    equipment or technology modifications, process or procedure 
    modifications, reformulation or redesign of products, substitution of 
    raw materials, and improvements in housekeeping, maintenance, training, 
    or inventory control), recycling, or conventional treatment. As an 
    example, if a facility can make process changes that reduce the mass of 
    cadmium by the same amount that would be removed if the prohibited 
    wastestream was treated to satisfy UTS, the facility would satisfy LDR 
    requirements. The facility could also remove cadmium from any of the 
    streams (prohibited or non-prohibited) which are going to be injected, 
    or could find a means of recycling some portion of the injectate to 
    reduce injected mass loadings of cadmium. In all cases, the result 
    would be that the mass loading of hazardous constituents into the 
    injection unit would be reduced by the same amount as it would be 
    reduced by treatment of the prohibited, characteristic portion of the 
    injectate. 976 F. 2d at 23 n. 8; see also Specialty Steel Inst. v. EPA, 
    27 F. 3d 642, 649 (D.C. Cir. 1994) (treatment standards that result in 
    lower volume of waste to be disposed--precisely what the alternative 
    standard here can achieve--are a permissible means of complying with 
    RCRA section 3004 (m)).
        Commenters further requested that this alternative be available on 
    a hazardous constituent by hazardous constituent basis. EPA agrees that 
    this is
    
    [[Page 15576]]
    reasonable since it still results in the requisite reduction of 
    hazardous constituent mass loading and provides desirable compliance 
    flexibility. Of course, if the pollution prevention alternative is used 
    partially, there must still be compliance by some alternative means for 
    the remaining hazardous constituents subject to the prohibition.
        The Agency is not, however, adopting any type of hazardous 
    constituent trading provision as part of this rule. It first is not 
    clear that such a provision would satisfy the equivalency test 
    enunciated by the court. In addition, given the narrow time frame 
    available to the Agency to develop this rule, the Agency lacks the time 
    and resources to properly evaluate the ramifications of the idea in 
    this proceeding.
        As a means of implementing this alternative, EPA is adopting the 
    method proposed. The mass/day reduction of a particular underlying 
    hazardous constituents is to be calculated by comparing the injected 
    baseline with the allowance. The injected baseline is determined by 
    multiplying the volume/day of prohibited hazardous waste generated and 
    subsequently injected times the concentration of hazardous constituents 
    before the pollution prevention measure. The allowance is determined by 
    multiplying the volume/day of a hazardous constituent generated/
    injected times the UTS for that constituent. The difference between the 
    injected baseline and the allowance is the required mass/day reduction.
        EPA proposed, and is adopting the requirement that after successful 
    employment of a pollution prevention measure, the facility must 
    demonstrate that the injected mass achieves the required mass/day 
    reduction. Because the amount of an underlying hazardous constituent in 
    the injectate is dependent upon the level of production, a correction 
    factor for production is needed. In the example given in the proposal 
    (60 FR 11714), the calculation for the injected baseline was corrected 
    by a production variability factor based on volume. The Agency had 
    solicited comment on whether there are production parameters other than 
    volume (e.g., mass, square footage, etc.). One commenter gave a 
    specific example where square footage would be a more appropriate 
    parameter. Therefore, the Agency is promulgating today that any 
    appropriate parameter may be used to calculate the production 
    variability factor. Another commenter was concerned that in the example 
    the baseline used after pollution prevention seemed to be based on the 
    production rate, whereas the baseline before pollution prevention was 
    not. The commenter misunderstood the purpose of the production 
    variability factor. In the example the post-pollution prevention 
    injectate was adjusted by the production variability factor; however, 
    the example could have been reorganized such that the initial baseline 
    was adjusted for production variability. It was not necessary to adjust 
    both the pre- and post-pollution prevention baselines for production 
    variabilty; in fact, doing so would cause the variability factor to 
    cancel out.
        Several commenters were concerned that there are other factors 
    besides rate of production which could cause variability in the level 
    of an underlying hazardous constituent. One commenter mentioned 
    variations in operation of specific source unit operations such as 
    distillation and/or stripping trains feeding the injection unit. 
    Another commenter stated that since they do not actually produce 
    anything, they have no production rates to use, and suggested basing 
    production on man-hours worked or total water consumed by a facility. 
    The Agency agrees with all these suggestions. The mass/day of an 
    underlying hazardous constituent after pollution prevention is based on 
    the flowrate multiplied by the concentration of the constituent, and 
    must be less than or equal to the calculated mass/day allowance for 
    that underlying hazardous constituent. Beyond this basic formula, the 
    facility can adjust for any factors which would cause a variation in 
    the concentration of the underlying hazardous constituent, provided the 
    variation(s) are part of a normal operating procedure.
        Under this approach, a facility would make a one-time change in 
    operating practice. Because the mass loading reductions resulting from 
    the practice are obtained from the time of the change forward, it 
    obviously is not necessary (and neither practical or likely feasible) 
    for the facility to make on-going (potentially daily) changes to 
    qualify under the provision.
        A number of commenters, although supporting the Agency's proposal, 
    argued that it should apply to facilities that already have implemented 
    source reduction or other pollution prevention practices before the 
    effective date of the rule, not just those making the change 
    prospectively (as EPA proposed). Their point is that facilities that 
    have already implemented source reduction, and as a result may now have 
    fewer opportunities to do so, should not be on a worse footing than 
    facilities who have been laxer and thus now have a wider range of 
    possible means of reduction. This argument certainly has equitable 
    force. At the same time, however, there has to be some objectively 
    defined baseline period for the rule to be enforceable, and for there 
    to be some nexus between the pollution prevention measure and the 
    reduced mass loadings in current injectate. Balancing these 
    considerations, the Agency is establishing 1990 as the base year for 
    establishing a baseline. This was the year EPA adopted (per 
    Congressional schedule) the prohibitions for characteristic hazardous 
    waste and (coincidentally) the year of the Pollution Prevention Act.
        EPA is sensitive to other comments regarding the need for this 
    alternative to be objectively verifiable. The Agency is therefore 
    requiring that facilities must monitor the underlying hazardous 
    constituent concentration and the volume of the prohibited hazardous 
    waste stream (i.e. all characteristic streams subject to LDR treatment 
    standard requirements that will be decharacterized before injection), 
    both on the day before and the day after successful implementation of 
    pollution prevention. Results of this monitoring must be reported to 
    the EPA Region or authorized State on a one-time basis. The Agency had 
    solicited comment on whether more than one day is needed for 
    monitoring. Several commenters were concerned that certain pollution 
    prevention methods would take several weeks, not one day, to show 
    results. It should be noted that the Agency did not intend for the 
    pollution prevention method to show results in one day. Results should 
    be achieved by the effective date of the rule for the facility to be in 
    compliance, and the pollution prevention method should have been 
    employed no earlier than 1990. The facility must also include a 
    description of the pollution prevention method used (including any 
    recycling alternative). In addition, the facility will monitor and keep 
    on-site records of the results on a quarterly basis (this time period 
    is selected to match the quarterly monitoring already required under 
    SDWA regulations at 40 CFR 146.13 (b)). If the facility changes its 
    means of complying with this alternative, it must renotify the EPA 
    Region or authorized State, and again document the basis for its 
    compliance by monitoring.
    
    D. De Minimis Volume Exemption
    
        EPA is finalizing the de minimis exemption proposed. 60 FR at 
    11714-11715. The terms of the exemption are that if decharacterized 
    wastewaters comprise no more than 1% of the total injectate, if the 
    total volume of the characteristic streams do not exceed 10,000 gallons 
    per day, and if underlying hazardous constituents are
    
    [[Page 15577]]
    present in the characteristic wastes at concentrations less than 10 
    times UTS at the point of generation, then the wastes are not 
    prohibited from injection in a Class I non-hazardous deepwell (assuming 
    the injectate is not hazardous at the point of injection). The Agency 
    continues to believe that under these circumstances, the relatively 
    small decharacterized hazardous waste streams would not appreciably 
    alter the risks posed by the injection practice.
        Generally, the proposed approach was well received. Some commenters 
    stated, however, that the de minimis volume exemption, as proposed, 
    would allow excessively large volumes of routinely generated 
    characteristic wastes to go untreated to disposal in deep wells, while 
    others believe that the specific quantifying parameters are overly 
    restrictive. The Agency analyzed potential risks associated with 
    concentrations of 5 contaminants detected in Class I facility waste 
    streams at 10, 20, and 50 times UTS. (This analysis was conducted in 
    conjunction with revising the Regulatory Impact Analysis For 
    Underground Injected Wastes for this rule. See 60 FR 11715.) In brief, 
    risk estimates for 4 geologic settings and 2 well malfunction scenarios 
    were found to be below levels of regulatory concern at 10 and 20 times 
    UTS. However, at 50 times UTS, risk estimates for cancer and hazard 
    index were above regulatory concern for a waste stream containing 
    carbon tetrachloride, assuming an abandoned borehole failure within 500 
    feet of the injection well. Taking into account the statutorily 
    enumerated ``long-term uncertainties associated with land disposal'' 
    (RCRA section 3004(d)(1)(A)), EPA believes the 10  x  UTS level to be 
    well within the zone of reasonable values it could select as de 
    minimis. The one percent volumetric requirement is consistent with 
    other longstanding de minimis exemptions for wastewater management 
    systems in the subtitle C rules (see Sec. 261.3(a)(2)(iv) (A) and (E)), 
    and would normally cap the total volume of characteristic injectate at 
    approximately 1100 gallons per day, given average Class I UIC non-
    hazardous injection rates.
        At a rate of 1100 gallons per day, 10 x UTS for carbon 
    tetrachloride would mean a mass loading of approximately 165 mg of the 
    constituents being injected each day. Mass loadings for the other 
    hazardous constituents would similarly be modest. EPA again believes 
    that these small mass loadings would have de minimis effect on the risk 
    potential posed by the injection practice and consequently should be 
    exempted from the prohibition.

        EPA is promulgating the treatment standards that were proposed for 
    wastes from the carbamate industry specified above.
        The preamble of the proposed rule described the basis for these 
    treatment standards in greater detail (60 FR 11720). For background 
    information on waste characterization data, data gathering efforts, and 
    applicable technologies, see the Best Demonstrated Available Technology 
    (BDAT) Background Document for Newly Listed or Identified Wastes from 
    the Production of Carbamates.
        The concentration-based treatment standards being promulgated today 
    for carbamate wastewaters and nonwastewaters are at UTS levels for 
    certain constituents, and at newly-established levels for other 
    constituents that are today being added to the UTS list. The UTS 
    standards have already been promulgated for 21 of the constituents of 
    concern (16 organic constituents and 5 metals). The Agency is 
    promulgating new UTS for 42 constituents associated with carbamate 
    wastes. Forty of these constituents are chemicals produced by the 
    carbamate industry which may be grouped into the following categories: 
    carbamates and carbamate intermediates, carbamoyl oximes, 
    thiocarbamates, and dithiocarbamates. Please refer to the Background 
    Document for definitions of these chemical groups and the 
    categorization of these 40 chemicals. The other 2 constituents for 
    which new UTS are being promulgated (triethylamine, and o-phenylene 
    diamine) are not carbamate products, but are hazardous constituents 
    present at levels of regulatory concern in carbamate wastes.
        One commenter requested clarification on the applicability of the 
    carbamate treatment standards, stating that the summary section of the 
    proposed treatment standards said that treatment standards were being 
    proposed for certain hazardous wastes ``including those from the 
    production of carbamate pesticides'', whereas the section of the rule 
    that directly addressed carbamate wastes referred to carbamates without 
    the pesticide limitation. EPA points out in response that the final 
    listing rule which defined the new waste codes does not limit the 
    definition to pesticides only. The treatment standards being 
    promulgated apply to all wastes which fit the definitions of the waste 
    codes established in the final listing rule.
        One commenter stated that EPA exceeded its authority under RCRA 
    section 3004 and violated the Administrative Procedure Act by preparing 
    the proposed treatment standards and sending this rule to OMB well 
    before the final listing had been promulgated. EPA points out that the 
    proposed treatment standards were actually published after publication 
    of the final listing rule. The proposed treatment standards were 
    modified to conform with the changes that appeared in the final 
    listing; thus, treatment standards were only proposed for those 
    carbamate wastes whose listing had been promulgated in final form. 
    Proposed standards for wastes whose listings were not finalized were 
    eliminated from the proposed treatment standards rule. Given the 
    statutory requirement described above (i.e., the requirement to 
    finalize LDR treatment standards six months after the listing is 
    finalized), Congress must have envisioned that the two rulemaking 
    activities would occur in close proximity.
        One commenter had several objections to the proposed standards for 
    thiocarbamate wastes, stating that 1) nonwastewater standards should 
    not have been based on detection limits compiled from sampling and 
    analysis performed as part of the listing process
    
    [[Page 15584]]
    because the Agency made errors in the sampling and analysis; 2) that 
    EPA has no data to support the assertion that the proposed UTS limits 
    can be met by thermal destruction technologies and that the source of 
    the detection limit used to develop the nonwastewater standard was not 
    clearly identified; and, 3) that no document was found in the record to 
    support the proposed wastewater limit of 0.003 mg/l for thiocarbamate 
    constituents (A2213, Butylate, Cycloate, EPTC, Molinate, Pebulate, 
    Prosulfocarb, Triallate, Vernolate), based on granular activated carbon 
    absorption, giving the commenter no basis to evaluate the achievability 
    of this treatment standard.
        To respond, the nonwastewater limit for thiocarbamate wastes was 
    actually based on a detection limit of 0.5 mg/kg by GC/NPD, identified 
    in a general characterization report addressing the newly regulated 
    constituents, rather than on the limit of 0.125 mg/kg by SW-846 8270B, 
    identified in the sampling and analysis reports. The commenter has not 
    yet provided any data to indicate that the proposed treatment standards 
    for nonwastewaters cannot be met.
        The Agency has decided to promulgate a treatment standard of 0.042 
    mg/l in wastewaters for the thiocarbamate constituents identified 
    above. This standard is based on an analytical detection limit of 0.015 
    mg/l for Butylate, identified in an activated carbon isotherm test 
    performed by the Office of Water to support development of effluent 
    guideline limitations. The Agency had proposed a wastewater limit of 
    0.003 mg/l, based on data taken from the PEST (Pesticide Treatability 
    Database) database containing treatability data for pesticides, 
    prepared and maintained by RREL (Risk Reduction Engineering Laboratory) 
    in Cincinnati, Ohio. However, upon review of the available data, the 
    Agency has decided that the Office of Water data is more accurately 
    representative of available wastewater treatment than the pilot-scale 
    data from the PEST database, and has decided to change the final 
    treatment standard accordingly.
        EPA is today clarifying that the LDRs do not apply to waste streams 
    which were specifically exempted from the definition of hazardous waste 
    in the final listing rule for carbamates. These waste streams include 
    sludges from the biological treatment of K156 and K157 and streams 
    which satisfy the concentration-based exemption from the definition of 
    K156 and K157 codified at Sec. 261.3(a)(2)(iv)(G).
        The promulgation of treatment standards for carbamate wastes has 
    greatly expanded the number of constituents covered by the Universal 
    Treatment Standards at Section 268.48. The Agency wishes to clarify 
    that only a very limited number of generators or treaters, such as 
    manufacturers or users of carbamate products, are expected to have 
    these new constituents present in their wastes. Therefore, affected 
    parties may rely on process knowledge to determine if it is necessary 
    to analyze for these constituents.
        The commenter has not yet provided any data to indicate that the 
    proposed treatment standards cannot be met. The commenter did indicate 
    an intention to submit biological treatment data for thiocarbamate 
    wastes. This commenter was instructed to submit this data quickly (by 
    the end of August) to allow the Agency time to give consideration to 
    this data prior to issuing the final rule.
    
    B. Spent Aluminum Potliners (K088)
    
    K088--Spent potliners from primary aluminum reduction.
    
        EPA proposed to establish treatment standards for K088 expressed as 
    numerical concentration limits (see 60 FR 11722) for the following 
    constituents: acenapthene, anthracene, benz(a)anthracene, 
    benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, 
    benzo(g,h,i)perylene, chrysene, dibenz(a,h)-anthracene, fluoranthene, 
    indeno(1,2,3-cd)pyrene, phenanthrene, pyrene, antimony, arsenic, 
    barium, beryllium, cadmium, chromium, lead, mercury, nickel, selenium, 
    silver, cyanide and fluoride. Today, EPA is promulgating these 
    treatment standards as proposed. The nonwastewater treatment standards 
    for cyanide, and the organic constituents, are based on a total 
    composition concentration analysis. The nonwastewater treatment 
    standards for fluoride, and the metal constituents, are based on 
    analysis using the TCLP. All wastewater treatment standards are based 
    on total composition concentration analysis.
    1. Comments Received on the ``Inherently Waste-Like'' Determination
        The majority of the comments received on the issue of declaring 
    K088 ``inherently waste-like'' opposed such a determination. As 
    discussed in the proposal, declaring K088 inherently waste-like would 
    require that all K088 treaters/recyclers obtain a RCRA Part B permit 
    regardless of whether the K088 is recycled, reused, used as a feedstock 
    in a process, or conventionally treated. The commenters asserted that 
    this designation would discourage recycling/reuse and development of 
    innovative technologies, and would be overly burdensome for many of the 
    small companies pursuing recycling technologies.
        The Agency was persuaded by commenters that a determination of 
    ``inherently waste-like'' is unnecessary at this time. Instead, any 
    determination of whether a particular K088 processing technology is a 
    type of excluded recycling activity would need to be made on a case-by-
    case basis by EPA Regions or authorized states. EPA was persuaded by 
    commenters that allowing individual flexibility in making such a 
    determination is desirable here.
        Criteria that are typically relevant in making any such 
    determinations are set out (among other places) at 50 FR at 638 (Jan. 
    4, 1985); 53 FR at 522 (Jan. 8, 1988); and 56 FR at 7159 and 7185 (Feb. 
    21, 1991). EPA also repeats the concerns voiced in the proposed rule 
    that spent aluminum potliners contain high concentrations of cyanides 
    and polyaromatic hydrocarbons which may be conventionally treated by 
    thermal recovery processes, and that these and other hazardous 
    constituents are present in the potliners in concentrations well 
    exceeding those found in the raw materials or products for which the 
    spent potliners would be substituting. 60 FR at 11723 n. 11. Other 
    concerns are that the thermal recovery processes appear to pose the 
    same potential risks of harmful air emissions as processing hazardous 
    wastes in industrial furnaces, that the residues of recovery processes 
    may not be adequately treated, and that storage of spent potliners can 
    (and indeed has) posed significant risk. Id. at 11723-24. EPA also 
    repeats that many of these units may already be subject to the rules 
    for industrial furnaces burning hazardous wastes, since those rules 
    apply to industrial furnaces that burn hazardous wastes for energy 
    recovery, material recovery, or destruction. Id. at 11722 and n. 10; 56 
    FR at 7142; 50 FR at 49171-49174 (Nov. 29, 1985); 40 CFR 266.100.
        A consequence of EPA's decision to allow for individualized 
    determinations is that it is also unnecessary (and indeed, not 
    factually justified) to make a general determination of ``substantial 
    confusion'' pursuant to 270.10(e)(2) which could establish an 
    opportunity for interim status eligibility. That finding would have 
    been premised on the generic inherently wastelike determination (see 60 
    FR at 11723), which the Agency is not making. EPA is also not pursuing 
    in this proceeding the idea of toxic air emission standards under 
    section 112(d)(1) of the Clean Air Act for these sources. These sources 
    could be subject to these standards if they are major (or, in some 
    cases, area)
    
    [[Page 15585]]
    sources under section 112, but that determination need not be part of 
    the present rulemaking.
    2. Comments Received on Regulated Constituents
        EPA requested comment on regulating the phthalates: bis (2-
    ethylhexyl) phthalate, di-n-butyl phthalate and di-n-octyl phthalate. 
    These constituents have seemingly been detected in the untreated 
    potliner and the treated residue; however, EPA believes that their 
    presence may simply be due to lab contamination. Commenters 
    overwhelmingly requested that these phthalates not be regulated. The 
    Agency agrees and is not including any phthalates in the list of 
    regulated constituents for K088.
        A number of commenters requested that benzo(a)pyrene be used as a 
    surrogate for analyzing organics. The commenters were concerned that 
    analytical costs for other PAHs would be excessive. EPA is not 
    convinced that analyzing benzo(a)pyrene would be sufficient for 
    determining proper treatment of all organics. The concentration of one 
    constituent does not always reflect the concentration of similar 
    constituents in a waste. Surrogate analyses assume that all PAHs are 
    present at similar concentrations which may or may not be true. Because 
    of the variability of concentrations found in K088 wastes, 
    benzo(a)pyrene may not be present while other PAHs may be present. 
    Analyzing only for benzo(a)pyrene or any other potential surrogate does 
    not ensure the treatment to UTS concentrations of other PAHs. In 
    addition, the Agency believes that since all of the PAHs are analyzed 
    by a single method the cost increase for additional PAHs should not be 
    significant. Therefore, the Agency does not believe the organic 
    constituents monitored in K088 wastes should be limited to a surrogate 
    indicator. EPA is allowing, however, flexibility in the waste analysis 
    plans developed by the companies with their permit writers to analyze 
    only for those constituents expected to be present in the generated 
    K088.
        The Agency proposed to regulate fluoride in K088. While fluoride is 
    not a ``hazardous constituent'', i.e., listed in Appendix VIII of part 
    261, it is present in very high concentrations in K088 and is capable 
    of causing substantial harm in the form of groundwater degradation, 
    adverse ecological effects and potential adverse human health effects. 
    The Agency's view thus is that, unless fluoride in this waste is 
    treated, the legal standard in section 3004(m) would not be satisfied. 
    That is, treatment would not ``substantially diminish the toxicity of 
    the waste * * * so that short-term and long-term threats to human 
    health and the environment are minimized.'' RCRA section 3004(m)(1). In 
    addition, as discussed in the proposed rule, EPA reads the language in 
    section 3004 (d)(1), (e)(1), and (g)(5) to require that land disposal 
    may still be prohibited after treatment of hazardous constituents if 
    the waste might still pose substantial hazards due to presence of other 
    constituents or properties. 56 FR at 41168 (August 19, 1991); NRDC v. 
    EPA, 907 F. 2d 1146, 1171-72 (D.C. Cir. 1990) (dissenting opinion). 
    These hazards could be posed due to lack of treatment of other 
    constituents in the waste, in this case, fluoride.
        The Agency requested comment on whether fluoride should be added to 
    Appendix VIII, as well. The overwhelming response of the commenters is 
    that fluoride should not be added to Appendix VIII. The Agency agrees 
    that fluoride does not pose the same risks in other wastes because it 
    does not occur in such high concentrations. Furthermore, adding 
    fluoride to Appendix VIII has associated potential analytical costs 
    which would be unwarranted. Therefore, even though the Agency is 
    regulating fluoride in K088, it is not adding it to Appendix VIII at 
    this time.
    3. Comments Received on Data
        Several comments were received regarding EPA's use of data on K088. 
    One comment in particular suggested that EPA ignored relevant data 
    gathered by the Aluminum Association. The Agency did not ignore these 
    data. They were submitted after the proposal and are currently in the 
    docket for this final rule. The Agency has reviewed these data and 
    found that they do not support any changes to the proposed treatment 
    standards that are being finalized in this rule. This issue is 
    discussed in greater detail in the Response to Comments background 
    document.
    4. Comments Received on Technical Basis for BDAT
        There were a number of comments submitted on the technical basis 
    for the numerical treatment standards. As described in the preamble to 
    the proposed rule, most of the treatment standards are taken from the 
    universal treatment standards (UTS) (59 FR 47988, September 19, 1994) 
    which were developed for each constituent by evaluating all existing 
    Agency data from various technologies. The exception to the UTS for 
    K088 constituents is the fluoride treatment standard, which was taken 
    from the Reynolds delisting petition. While K088 is a unique waste, 
    available data indicate that these UTS levels can be routinely 
    achieved.
        There seemed to be some confusion in that some commenters believed 
    that EPA was proposing a required technology for the treatment of K088. 
    This is not the case. The longstanding position of the Agency is when 
    numerical treatment levels are established under the LDR program, any 
    treatment technology (other than impermissible dilution) can be used to 
    achieve those levels.
        Additional K088 comments along with EPA's responses are provided in 
    the Response to Comments Background Document located in the docket for 
    this rule.
    
    VI. Improvements to the Existing Land Disposal Restrictions Program
    
    A. Completion of Universal Treatment Standards
    
    1. Addition of Constituents to Table 268.48
        As discussed in the section on carbamate wastes, EPA is today 
    adding 42 new constituents to the table of universal treatment 
    standards (Table 268.48), for which treatment standards are being 
    promulgated today.
    2. Wastewater Standard for 1,4-Dioxane
        EPA proposed on March 2, 1995 (60 FR 11702), to establish a 
    wastewater treatment standard for 1,4-dioxane. 1,4-Dioxane was the only 
    UTS constituent for which EPA had promulgated a nonwastewater treatment 
    standard but not a wastewater standard. At that time, the Agency 
    proposed a wastewater UTS for 1,4-dioxane of 0.22 mg/l. This proposed 
    standard was based on the maximum daily limit for 1,4-dioxane that had 
    been developed as part of the proposed effluent guidelines for the 
    pharmaceutical industry (60 FR 21592, May 2, 1995). This standard was 
    based on a transfer of distillation performance data from methanol to 
    1,4-dioxane.
        Today, the Agency is promulgating a revised treatment standard for 
    wastewater forms of 1,4-dioxane based on 5 data points. This data was 
    submitted by one of the commenters and represents actual treatment of 
    wastewaters containing 1,4-dioxane. The Agency prefers to use actual 
    treatment data in lieu of a data transfer whenever possible. These data 
    show that wastewaters containing between 2265-7365 mg/l of 1,4-dioxane 
    can be treated by distillation to levels between 3-7 mg/l, representing 
    a 99.9% removal rate for the dioxane. As a result of this data 
    submittal, the Agency is today promulgating a UTS of 12.0 mg/l for 1,4-
    
    [[Page 15586]]
    dioxane wastewaters based on the performance of distillation. The 
    standard was calculated following the standard methodology employed by 
    EPA in developing all BDAT treatment standards.
        Comments received on the wastewater treatment standard for 1,4-
    dioxane focused on three major points: (1) The unavailability, at the 
    time of proposal, of data from the effluent guidelines proposed rule 
    for the pharmaceutical industry, from which the proposed standard had 
    been derived; (2) the inappropriateness of transferring distillation 
    data from methanol to 1,4-dioxane (based on the effluent guidelines 
    data); and (3) analytical difficulties inherent in analyzing for 1,4 
    dioxane in wastewater.
        In the proposed rule, EPA referenced effluent guidelines data that 
    would be made available to support the proposed wastewater treatment 
    standard for 1,4-dioxane (60 FR 11727, footnote 13). Although the 
    Agency believed that these data would be available for public 
    inspection shortly after signature of the proposed rule, this was not 
    the case. The data were available one day following the close of the 
    comment period on the Phase III proposed rule. As a result, many 
    comments were received that criticized the Agency for not providing 
    appropriate pubic review of data that was used to develop a treatment 
    standard.
        In light of the delayed release of the effluent guidelines data, 
    the Agency decided to accept comments on these data and the proposed 
    1,4-dioxane treatment standard for 30 additional days. In addition, the 
    Agency provided notice of this extension to all commenters of the 
    proposed rule. Several comments were received in response to this memo. 
    Most of the commenters who had raised issue with the proposed standard 
    commented on the EPA memo.
        In response to the second concern raised by commenters, the Agency 
    has received actual wastewater treatment data on 1,4-dioxane and as 
    such has developed a UTS based on that data. As stated earlier, the 
    Agency prefers to use actual constituency data from available treatment 
    technology in lieu of transferred data from other constituents whenever 
    feasible.
        Finally, several commenters raised concerns regarding the 
    analytical difficulties of reliably detecting and quantifying 1,4-
    dioxane in wastewater. CMA, in particular, stated that any UTS under 20 
    mg/l for 1,4-dioxane would be impractical. Other commenters noted 
    extreme variability and difficulty in testing for the presence of 1,4-
    dioxane in wastewaters. While the analytical results provided by one of 
    the commenters did show some irregularities, a comprehensive analytical 
    protocol was not provided by the any of the comments which would be 
    needed to fully assess their concerns regarding 1,4-dioxane. As such, 
    the Agency believes that there should be no difficulty in analyzing for 
    1,4-dioxane in wastewater. Analysis can be accomplished by either 
    direct injection into a GCFID (SW 846, Method 8015B) or a more 
    sensitive analysis involving the injection of an azeotropic distillate 
    preparation into a GCFID (SW-846, Method 5031).
    3. Revision to the Acetonitrile Standard
        EPA proposed to raise the UTS for the nonwastewater form of 
    acetonitrile from 1.8 mg/kg to 38 mg/kg. Commenters generally supported 
    this revision for the reasons given in the proposed rule. Therefore the 
    Agency is promulgating this revised treatment standard in this rule for 
    the reasons stated at 60 FR 11729.
        Related to this, EPA also proposed revoking the special wastewater/
    nonwastewater definition for acrylonitrile wastes (K011/13/14), 
    recognizing that these nonwastewaters could consist of over 90% water, 
    and that wastewater treatment is an appropriate means of treating these 
    wastes. Commenters agreed with this, and the Agency is finalizing this 
    today.
    
    B. Aggressive Biological Treatment as BDAT for Petroleum Refinery 
    Wastes
    
        EPA had solicited comment on whether to specify aggressive 
    biological treatment (ABT) as the treatment standard for 
    decharacterized petroleum refining wastewaters. The Agency is not 
    establishing such a treatment standard in this final rule, but is 
    instead promulgating a reduction in the frequency of monitoring 
    required for those facilities using ABT to treat their wastes. The 
    reasons for this are discussed below.
        This issue was raised by the American Petroleum Institute (API), 
    which had submitted data to the Agency on ten of its facilities that 
    used aggressive biological treatment. Along with the data, API 
    requested that EPA specify aggressive biological treatment as the 
    treatment standard for their wastes. Such a standard, which would 
    operate in lieu of UTS, would, in API's view, provide adequate 
    treatment and could reduce their monitoring burden. In a similar vein, 
    CMA commented that EPA should specify an optional treatment method 
    (biological treatment) as an alternative to meeting UTS for underlying 
    hazardous constituents reasonably expected to be present in 
    characteristic wastes.
        The Environmental Technology Council (ETC) opposed setting ABT as a 
    new technology-specific treatment standard. They argued that biological 
    treatment only partially destroys underlying hazardous constituents. 
    They also felt that reducing the monitoring burden is inadequate 
    justification for creating a new technology-specific standard.
        As discussed in the preamble to the proposed rule (60 FR at 11719), 
    biotreatment systems vary in performance both in general and as to 
    specific constituents; the Agency is therefore reluctant to designate 
    ABT as BDAT based on data from only ten facilities. The main reason 
    given by both API and CMA for having a treatment method as the 
    treatment standard was the elimination of the compliance monitoring 
    burden. Although we agree with ETC that reducing monitoring burden is 
    not an adequate justification for creating a new technology-specific 
    treatment standard, EPA is certainly willing to consider more efficient 
    means of ensuring compliance with LDR requirements.
        Therefore, EPA is not designating ABT as BDAT, but is, however, 
    requiring that decharacterized wastes affected by today's rule, which 
    are managed in a wastewater treatment system involving ABT, must be 
    monitored annually to ensure compliance with the treatment standards 
    for underlying hazardous constituents. Other decharacterized wastes 
    affected by today's rule must be monitored quarterly. EPA has been 
    reviewing the paperwork burden posed by the LDR program; this was 
    discussed in the supplemental notice to the LDR Phase IV proposed rule 
    (61 FR 2338, January 25, 1996). As part of this paperwork burden 
    reduction effort, the Agency is considering reducing the monitoring 
    burden for all facilities complying with LDRs. The Agency considers 
    reducing the monitoring burden for facilities treating wastewater with 
    ABT to be a positive step towards this goal, and therefore believes it 
    is justified. Reductions of this type for other types of treatment will 
    be explored in future rulemakings.
    
    C. Dilution Prohibition
    
        Under the existing LDR dilution prohibition (40 CFR 268.3), burning 
    inorganic metal-bearing hazardous wastes can be a form of impermissible 
    dilution. On May 27, 1994, the Assistant Administrator for the Office 
    of Solid Waste and Emergency Response issued
    
    [[Page 15587]]
    a Statement of Policy which clarified this point (59 FR 27546-27547). 
    Today the Agency is codifying and quantifying these principles.
        As discussed in the proposed rule, impermissible dilution may occur 
    when wastes not amenable to treatment by a certain method (i.e., 
    treated very ineffectively by that treatment method) are nevertheless 
    `treated' by that method (55 FR 22666, June 1, 1990; 52 FR at 25778-
    25779, July 8, 1987). Today's rule provides a general distinction 
    between ``adequate treatment'' and potential violations of the dilution 
    prohibition.
    1. Inorganic Metal-Bearing Wastes
        The Agency has evaluated the hazardous wastes and has determined 
    that 43 of the RCRA listed wastes (as set forth in 40 CFR part 261) 
    typically appear to be inorganic hazardous wastes that do not contain 
    organics, or contain only insignificant amounts of organics, and are 
    not regulated for organics. BDAT for these inorganic, metal-bearing 
    listed wastes is metal recovery or stabilization. Thus, impermissible 
    dilution may result when these wastes are combusted. When an inorganic 
    metal-bearing hazardous waste with insignificant concentrations of 
    organics is placed in a combustion unit, legitimate treatment for 
    purposes of LDR ordinarily is not occurring. No treatment of the 
    inorganic component occurs during combustion, and therefore, metals are 
    not destroyed, removed, or immobilized. Since there are no significant 
    concentrations of organic compounds in inorganic metal-bearing 
    hazardous wastes, it cannot be maintained that the waste is being 
    properly or effectively treated via combustion (i.e., thermally treated 
    or otherwise destroyed, removed, or immobilized). For this reason, 
    combustion of inorganic wastes is not a ``metho[d] of treatment * * * 
    which substantially diminish[es] the toxicity of the waste or 
    substantially reduce[s] the likelihood of migration of hazardous 
    constituents from the waste * * *'' (RCRA Sec. 3004(m)) and so is not a 
    permissible method of treatment under that provision.
        In terms of the dilution prohibition, if combustion is allowed as a 
    method to achieve a treatment standard for these wastes, metals in 
    these wastes will be dispersed to the ambient air and will be diluted 
    by being mixed in with combustion ash from other waste streams. 
    Adequate treatment (stabilization or metal recovery to meet LDR 
    treatment standards) has not been performed and dilution has occurred. 
    It is also inappropriate to regard eventual stabilizing of such 
    combustion ash as providing adequate treatment for purposes of the 
    LDRs. Simply meeting the numerical BDAT standards for the ash fails to 
    account for metals in the original waste stream that were emitted to 
    the air and for reductions achieved by dilution with other materials in 
    the ash. (In most cases, of course, the metal-bearing wastes will have 
    been mixed with other wastes before combustion, which mixing itself 
    could be viewed as impermissible dilution).
        These inorganic, metal-bearing hazardous wastes should be--and are 
    usually--treated by metal recovery or stabilization technologies. These 
    technologies remove hazardous constituents through recovery in 
    products, or through immobilization, and are therefore permissible BDAT 
    treatment methods.
        There are eight characteristic metal wastes; however, only wastes 
    that exhibit the TC as measured by both the TCLP and the EP for D004-
    D011 are presently prohibited (see 55 FR 22660-22662, June 1, 1990). 
    EPA recently proposed prohibition and treatment standards for wastes 
    identified as hazardous solely because they exhibit the TC (60 FR at 
    43682, August, 22, 1995). Characteristic wastes, of course, cannot be 
    generically characterized as easily as listed wastes because they can 
    be generated from many different types of processes. For example, 
    although some characteristic metal wastes do not contain organics or 
    cyanide or contain only insignificant amounts, others may have organics 
    or cyanide present which justify combustion, such as a used oil 
    exhibiting the TC characteristic for a metal. Thus, it is difficult to 
    say which D004-D011 wastes would be impermissibly diluted when 
    combusted, beyond stating that as a general matter, impermissible 
    dilution would occur if the D004-D011 waste does not have significant 
    organic or cyanide content but is nevertheless combusted.
        An ``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. The table being promulgated in 40 CFR part 268, Appendix XI is 
    the list of waste codes for which EPA regulates only metals that are 
    affected by this rule.
    2. Inorganic Metal-Bearing Wastes Not Prohibited Under the LDR Dilution 
    Prohibition
        Combustion of the following inorganic metal-bearing wastes is not 
    prohibited under the LDR dilution prohibition: (1) wastes that, at the 
    point of generation, or after any bona fide treatment such as cyanide 
    destruction prior to combustion, contain hazardous organic constituents 
    or cyanide at levels exceeding the constituent-specific treatment 
    standard for UTS; (2) organic, debris-like materials (e.g., wood, 
    paper, plastic, or cloth) contaminated with an inorganic metal-bearing 
    hazardous waste; (3) wastes that, at point of generation, have 
    reasonable heating value such as greater than or equal to 5000 Btu/lb 
    (see 48 FR 11157, March 16, 1983); (4) wastes co-generated with wastes 
    that specify combustion as a required method of treatment; (5) wastes, 
    including soil, subject to Federal and/or State requirements 
    necessitating reduction of organics (including biological agents); and 
    (6) wastes with greater than 1% Total Organic Carbon (TOC).
        Several commenters want EPA to add additional criteria. One 
    commenter recommended adding a seventh criterion, i.e., combustion that 
    results in a significant reduction in volume. Several commenters 
    recommended adding a seventh criterion to allow combustion of lab 
    packs. The Agency is not persuaded that a seventh criterion is 
    necessary. It has determined that volume reduction is not a sufficient 
    reason to allow the combustion of inorganic metal-bearing wastes 
    because metals are neither destroyed nor immobilized, and it is 
    possible that a significant amount of metal is being transferred to 
    another media. As for lab packs, in the Phase II final rule (59 FR 
    47982, September 19, 1994), the Agency specifically addressed lab pack 
    issues when it revised 268 Appendix IV to specify those wastes that are 
    prohibited from inclusion in lab packs destined for combustion. Today's 
    dilution prohibition does not supersede the streamlined treatment 
    standards promulgated in the Phase II final rule. Therefore, metal-
    bearing inorganic wastes may be included in a lab pack unless it is 
    prohibited under the list of wastes in 268 Appendix IV.
    3. Cyanide-Bearing Wastes
        A commenter questioned why EPA allows the presence of cyanide to 
    justify combustion when there are adequate alternative treatment 
    methods for that waste constituent. This approach was adopted because 
    cyanide is destroyed--i.e., effectively treated and not diluted--by 
    combustion. Existing LDR rules, in many cases, identify combustion as 
    an appropriate BDAT for destruction of cyanide-bearing wastes. See, 
    e.g., treatment standards for F009, F010, and F011. The LDR Phase III 
    proposal solicited comments on whether the
    
    [[Page 15588]]
    cyanide criterion should be dropped. Several commenters strongly 
    supported the continued use of combustion as a treatment method for 
    cyanide-bearing wastes, stating that combustion is the most efficient 
    and effective method for treating cyanide wastes. One commenter, ETC, 
    supported dropping the cyanide criterion because of the existence of 
    alternative non-combustion technologies to treat inorganic cyanide-
    bearing wastes without dispersing metals. The Agency disagrees; 
    combustion, when properly conducted, can effectively destroy all the 
    cyanide in a waste. In the Agency's view, this indicates that cyanide 
    wastes which are treated by combustion are not being diluted 
    impermissibly. This issue of whether metals are being dispersed would 
    be addressed through substantive controls on the combustion unit.
    4. Table of Inorganic Metal Bearing Wastes
        The table being promulgated in 40 CFR part 268, Appendix XI today 
    indicates the list of waste codes for which EPA regulates only metals 
    and/or cyanides that would be affected by this proposed rule. Except 
    for P122, this list is identical to the list originally published in 
    the aforementioned Policy Statement on this subject. The Agency is 
    removing P122 (Zinc Phosphide greater than 10%) from the list of 
    restricted inorganic metal-bearing wastes, because the Agency has 
    previously promulgated a treatment standard of INCIN for the 
    nonwastewater forms of this waste. See 40 CFR 268.40. The policy memo 
    was in error on this point. EPA wishes to clarify that this dilution 
    prohibition is limited to the 51 waste codes in this table. In 
    addition, if an Appendix IX waste meets any of the six criteria 
    discussed above, it would be permissible to combust the waste despite 
    the fact that it is an Appendix IX waste.
    
    D. Expansion of Treatment Options That Will Meet the LDR Treatment 
    Standard ``CMBST''
    
        EPA is modifying the treatment standard expressed as INCIN, which 
    specifies hazardous waste incineration, to CMBST, which allows 
    combustion in incinerators, boilers and industrial furnaces. EPA also 
    solicited comment on whether the Catalytic Extraction Process, for 
    which Molten Metal Technology received a determination of equivalent 
    treatment under Sec. 268.42(b), should also be allowed for all wastes 
    which have a treatment standard of CMBST, and whether there are other 
    technologies which are equivalent to CMBST. Commenters supported the 
    inclusion of the Catalytic Extraction Process (CEP), and since the 
    Agency has determined that (properly operated) it performs in a manner 
    equivalent to other combustion technologies, is adding it to the CMBST 
    standard. Molten Metal Technology commented that the CEP is not in fact 
    a combustion technology, and the Agency has attempted to reflect this 
    in the definition. One commenter, Exide Corporation, requested that 
    their plasma arc process for the recovery of lead also be added to the 
    definition of CMBST. The Exide plasma arc process is in fact an 
    industrial furnace under Sec. 260.10, and is therefore already 
    considered part of the definition of CMBST.
        EPA also notes that the new CMBST standard requires that wastes be 
    thermally treated in units that either are subject to subtitle C 
    standards, or, in cases where non-hazardous but prohibited wastes are 
    being thermally treated, in accordance with applicable technical 
    operating requirements. This situation could arise, for example, if a 
    decharacterized waste were then being thermally treated. Such a waste 
    need not be managed in a hazardous waste combustion unit. The 
    regulatory language makes clear that non-hazardous waste combustion 
    units can be utilized. In fact, the predecessor to the CMBST standard--
    INCIN--allowed nonhazardous incinerators to be an eligible type of unit 
    because the INCIN standard allowed burning in units subject to 
    applicable emissions standards, which standards did not necessarily 
    have to include subtitle C standards (59 FR 48002, Sept. 19, 1994, and 
    60 FR 242, June 3, 1995). This language was omitted inadvertently from 
    the CMBST standard, and is being restored in today's rule.
    
    E. Clean Up of 40 CFR Part 268
    
        EPA is finalizing changes to the LDR program to achieve the goal of 
    simplified regulations.
    1. Section 268.8
        Because treatment standards for all scheduled wastes were 
    promulgated in the Third Third rule in 1990, the Sec. 268.8 ``soft 
    hammer'' requirements are no longer necessary. Therefore, Sec. 268.8 is 
    removed from part 268.
    2. Sections 268.10-268.12
        The purpose of Subpart B of 268 was to set out a schedule for 
    hazardous wastes by the date when treatment standards were to be 
    established. Deadlines in all three of these sections were met on time, 
    and the wastes are subject to treatment standards. Therefore, these 
    three sections are no longer necessary, and are removed.
    3. Section 268.2(f)
        With the promulgation of UTS in the LDR Phase II final rule (59 FR 
    47982, September 19, 1994), distinctions in the definitions of 
    wastewaters are unnecessary. The Agency is therefore removing 
    paragraphs (1)-(3) from Sec. 268.2(f).
    4. Corrections to Proposed Rule Language
        A number of commenters pointed out properly that EPA had proposed 
    an amendment to Sec. 268.9 of the rules which would have the effect of 
    subjecting all listed wastes which also exhibit a characteristic of 
    hazardous waste to evaluate whether the waste contains underlying 
    hazardous constituents not covered by the treatment standard for the 
    listed waste, and if so, to treat for them. See 60 FR at 11741. EPA 
    agrees with the commenters that this provision is unnecessary and is 
    not adopting it. (In fact, the Agency did not intend any far-reaching 
    change in proposing the revised language.) The provision is unnecessary 
    because EPA already evaluated which hazardous constituents are present 
    in listed wastes at the time of developing the treatment standards (any 
    of the Background Documents supporting the treatment standards 
    indicates the sampling done, and that the sampling encompassed the 
    whole range of hazardous constituents potentially present). There is no 
    need to duplicate this effort. Consequently, the Agency is not amending 
    Sec. 268.9(b).
        Other commenters pointed out that the proposed changes to the de 
    minimis exemption in Sec. 268.1(e)(4)(i) (see 60 FR 11740) 
    inadvertently omitted the language which states that de minimis losses 
    are not prohibited. That language has been put back into the final rule 
    language.
    
    VII. Capacity Determinations
    
    A. Introduction
    
        This section summarizes the results of the capacity analysis for 
    the wastes covered by this rule. For background information on data 
    sources, methodology, and a summary of each analysis, see the 
    Background Document for Capacity Analysis for Land Disposal 
    Restrictions, Phase III--Decharacterized Wastewaters, Carbamate Wastes, 
    and Spent Potliners, found in the docket for today's rule. For EPA's 
    responses to capacity-related comments, see the Response to Capacity-
    Related Comments Received on the Phase III
    
    [[Page 15589]]
    Land Disposal Restrictions Rulemaking, also found in the docket for 
    today's rule.
        In general, EPA's capacity analysis methodologies focus on the 
    amount of waste to be restricted from land disposal that is currently 
    managed in land-based units and that will require alternative treatment 
    as a result of the LDRs. The quantity of wastes that are not managed in 
    land-based units (e.g., wastewaters managed only in RCRA exempt tanks, 
    with direct discharge to a POTW) is not included in the quantities 
    requiring alternative treatment as a result of the LDRs. Also, wastes 
    that do not require alternative treatment (e.g., those that are 
    currently treated using an appropriate treatment technology) are not 
    included in these quantity estimates.
        EPA's decisions on whether to grant a national capacity variance 
    are based on the availability of alternative treatment or recovery 
    technologies. Consequently, the methodology focuses on deriving 
    estimates of the quantities of waste that will require either 
    commercial treatment or the construction of new on-site treatment 
    systems as a result of the LDRs--quantities of waste that will be 
    treated adequately either on site in existing systems or off site by 
    facilities owned by the same company as the generator (i.e., captive 
    facilities) are omitted from the required capacity estimates.
    
    B. Capacity Analysis Results Summary
    
        For the decharacterized ICR and TC wastes managed in CWA, CWA-
    equivalent, and Class I injection well systems, EPA estimates that 
    between 85 and 500 million tons per year (estimated at end-of-pipe) 
    will be affected as a result of today's rule. EPA believes that many 
    affected facilities need time to build treatment capacity for these 
    wastes, as wastewater volumes generally make off-site treatment 
    impractical. Thus, EPA has determined that sufficient alternative 
    treatment capacity is not available, and today is granting a two-year 
    national capacity variance for decharacterized wastewaters.
        Commenters to the rule generally supported EPA's decision to grant 
    a national capacity variance for decharacterized wastes managed in CWA, 
    CWA-equivalent, and Class I injection well systems. Numerous other 
    comments were received on issues such as those associated with the 
    definition of point of generation for ICR and TC wastewaters and the 
    applicability of today's rule to wastewater management units other than 
    surface impoundments, such as stormwater impoundments, sumps, sewers, 
    and trenches. The Response to Capacity-Related Comments Received on the 
    Phase III Land Disposal Restrictions Rulemaking background document 
    provides a detailed discussion of the capacity-related comments on 
    decharacterized wastewaters and EPA's response to them.
        To assess the quantity of D003 wastes that could be affected by the 
    rule other than those wastes managed in CWA and CWA-equivalent systems, 
    EPA extracted information from the 1993 Biennial Reporting System (BRS) 
    on the generation and management of D003 wastes. According to the BRS, 
    approximately 2.2 million tons of D003 wastewaters are currently 
    deepwell injected, 650 tons of D003 nonwastewaters are managed through 
    land application, and 17,600 tons of D003 nonwastewaters are managed in 
    ``other'' disposal units (not specified in the BRS). These wastes may 
    require additional treatment in order to meet the LDRs. In addition, 
    some D003 waste that may be affected by the rule may not be reported in 
    the BRS, because these wastes may not be considered hazardous by the 
    generator once they have been decharacterized. Although EPA believes 
    that in general there is adequate treatment capacity for these wastes, 
    such capacity may not be immediately available. Therefore, EPA is 
    granting a 90-day capacity variance for D003 wastes that are impacted 
    by the rule and are not managed in CWA and CWA-equivalent systems in 
    order to allow facilities time to determine whether their wastes are 
    affected by this rule, and identify and locate alternative treatment 
    capacity if necessary.
        EPA estimates that approximately 105,000--130,000 tons of newly 
    listed wastes included in today's rule will require alternative 
    treatment. In particular, approximately 4,500 tons of carbamate wastes 
    (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, U407, U409-U411) will require alternative treatment. 
    In addition, 100,000--125,000 tons (not including contaminated media) 
    of spent aluminum potliners (K088) will require alternative treatment 
    capacity.
        EPA received a number of comments on its capacity analysis for K088 
    wastes. Most commenters disagreed with EPA's proposal not to grant a 
    capacity variance for K088 wastes. Specifically, these commenters 
    believe that EPA overestimated the quantity of available capacity and 
    underestimated the quantity of required capacity. In performing the 
    capacity analysis for the final rule, EPA considered all of the issues 
    raised by the commenters and reexamined its estimates of both available 
    and required capacity. EPA found that adequate treatment capacity does 
    exist for K088 wastes, although the amount of treatment capacity 
    appears to be just adequate to accommodate demand. However, some of the 
    facilities capable of treating these wastes may require pretreatment 
    such as grinding or crushing prior to accepting the waste. In order to 
    allow facilities generating K088 adequate time to work out logistics 
    such as transportation, pretreatment capacity, and contracting for 
    treatment capacity, EPA has decided to grant a nine-month national 
    capacity variance for these wastes--the time at which EPA estimates 
    existing treatment capacity will be available as a practical matter. A 
    detailed discussion of the final capacity analysis is provided in the 
    Background Document for Capacity Analysis for Land Disposal 
    Restrictions, Phase III--Decharacterized Wastewaters, Carbamate Wastes, 
    and Spent Potliners and EPA's responses to the individual comments on 
    the K088 capacity analysis are provided in the Response to Capacity-
    Related Comments Received on the Phase III Land Disposal Restrictions 
    Rulemaking, both of which are in the docket for today's rule.
        EPA has determined that there is adequate alternative treatment 
    capacity available for the 4,500 tons of carbamate wastes generated 
    each year and is therefore not granting a national capacity variance 
    for these wastes.
        The quantities of radioactive wastes mixed with wastes included in 
    today's rule are generated primarily by the U.S. Department of Energy 
    (DOE). EPA estimates that 820 tons of high-level waste and 360 tons of 
    mixed low-level waste that may be affected by this proposal will be 
    generated annually by DOE. In addition, there are currently 7,000 tons 
    of high-level waste, 10 tons of mixed transuranic waste, and 2,700 tons 
    of mixed low-level waste in storage that may be affected by this rule. 
    DOE currently faces treatment capacity shortfalls for high-level wastes 
    and mixed transuranic wastes. Although DOE does have some available 
    treatment capacity for mixed low-level wastes, most of this capacity is 
    limited to treatment of wastewaters with less than one percent total 
    suspended solids and is not readily adaptable for other waste forms. 
    DOE has indicated that it will generally give treatment priority to 
    mixed wastes that are already restricted under previous LDR rules. 
    Therefore, EPA is granting a two-year national capacity variance to 
    radioactive wastes mixed with the hazardous wastes affected by today's 
    rule. Commenters to the proposed rule supported EPA's
    
    [[Page 15590]]
    decision to grant a national capacity variance for these wastes.
        Table 1 lists each RCRA hazardous waste code for which EPA is today 
    promulgating LDR standards. For each code, this table indicates whether 
    EPA is granting a national capacity variance for land-disposed wastes. 
    Also, EPA is granting a three-month national capacity variance for all 
    wastes in this rule to handle logistical problems associated with 
    complying with the new standards.

    VIII. State Authority
    
    A. Applicability of Rules in Authorized States
    
        Under section 3006 of RCRA, EPA may authorize qualified States to 
    administer and enforce the RCRA program within the State. Following 
    authorization, EPA retains enforcement authority under sections 3008, 
    3013, and 7003 of RCRA, although authorized States have primary 
    enforcement responsibility. The standards and requirements for 
    authorization are found in 40 CFR Part 271.
        Prior to HSWA, a State with final authorization administered its 
    hazardous waste program in lieu of EPA administering the Federal 
    program in that State. The Federal requirements no longer applied in 
    the authorized State, and EPA could not issue permits for any 
    facilities that the State was authorized to permit. When new, more 
    stringent Federal requirements were promulgated or enacted, the State 
    was obliged to enact equivalent authority within specified time frames. 
    New Federal requirements did not take effect in an authorized State 
    until the State adopted the requirements as State law.
        In contrast, under RCRA section 3006(g) (42 U.S.C. 6926(g)), new 
    requirements and prohibitions imposed by HSWA take effect in authorized 
    States at the same time that they take effect in unauthorized States. 
    EPA is directed to carry out these requirements and prohibitions in 
    authorized States, including the issuance of permits, until the State 
    is granted authorization to do so.
        Today's rule is being promulgated pursuant to sections 3004(d) 
    through (k), and 3004(m), of RCRA (42 U.S.C. 6924(d) through (k), and 
    6924(m)). Therefore, the Agency is adding today's rule to Table 1 in 40 
    CFR 271.1(j), which identifies the Federal program requirements that 
    are promulgated pursuant to HSWA. States may apply for final 
    authorization for the HSWA provisions in Table 1, as discussed in the 
    following section of this preamble. Table 2 in 40 CFR 271.1(j) is also 
    modified to indicate that this rule is a self-implementing provision of 
    HSWA.
    
    B. Abbreviated Authorization Procedures for Specified Portions of 
    Today's Rule
    
        On August 22, 1995, EPA proposed in the Phase IV LDR notice an 
    abbreviated authorization procedure that would also be used for certain 
    parts of the Phase III LDR rule that are minor in nature (EPA also 
    proposed to use this procedure for the Universal Treatment Standards 
    (UTS) in the Phase II rule). This procedure is designed to expedite the 
    authorization process by reducing the scope of a State's submittal, for 
    authorization to a State certification and copies of applicable 
    regulations and statutes. EPA would then conduct a short review of the 
    State's request, primarily consisting of a completeness check (see 60 
    FR 43686 for a full description of the proposed procedures). The parts 
    of the Phase III rule to which the streamlined authorization procedures 
    would be applicable are: (1) treatment standards for newly listed 
    wastes, (2) improvements to the existing land disposal restrictions 
    program, and (3) revisions and corrections to the treatment standards 
    in Secs. 268.40 and 268.48. (Further discussion of this issue also is 
    found in the supplemental proposal to the LDR Phase IV rule (61 FR 
    2358, 2365, January 25, 1996)).
        Although EPA is firmly committed to streamlining the RCRA State 
    authorization procedures, the Agency has decided not to finalize the 
    proposed Category 1 authorization procedures for parts of the Phase III 
    rule today's notice. EPA believes that public comments from both the 
    August 22 proposal and comments submitted for the recent HWIR-
    contaminated media proposal should be considered before finalizing new 
    procedures for authorization. This full consideration will enable EPA 
    to make the best decision regarding how the authorization process 
    should work. EPA intends to finalize both the Category 1 and Category 2 
    procedures at the same time.
    
    C. Effect on State Authorization
    
        Because today's Phase III LDR rule is being promulgated under HSWA 
    authority, those sections of today's rule that expand the coverage of 
    the LDR program (e.g., to newly identified wastes) would be implemented 
    by EPA on the effective date of today's rule in authorized States until 
    their programs are modified to adopt these rules and the modification 
    is approved by EPA.
        However, some of today's regulatory amendments are neither more or 
    less stringent than the existing Federal requirements. EPA clarified in 
    a December 19, 1994, memorandum (which is in the docket for today's 
    rule) that EPA would not implement the Universal Treatment Standards 
    (promulgated under HSWA authority in the Phase II LDR rule) separately 
    for those States for which the State has received LDR authorization. 
    EPA views any changes from the existing limits to
    
    [[Page 15591]]
    be neither more or less stringent since the technology basis of the 
    standards has not changed. Accordingly, EPA will not implement the 
    amendments to the UTS in today's LDR Phase III rule for those states 
    with LDR authorization.
        Because today's rule is promulgated pursuant to HSWA, a State 
    submitting a program modification may apply to receive interim or final 
    authorization under RCRA section 3006(g)(2) or 3006(b), respectively, 
    on the basis of requirements that are substantially equivalent or 
    equivalent to EPA's. The procedures and schedule for State program 
    modifications for final authorization are described in 40 CFR 271.21. 
    It should be noted that all HSWA interim authorizations will expire 
    January 1, 2003. (See Sec. 271.24 and 57 FR 60132, December 18, 1992.)
        Section 271.21(e)(2) requires that States with final authorization 
    must modify their programs to reflect Federal program changes and to 
    subsequently submit the modification to EPA for approval. The deadline 
    by which the State would have to modify its program to adopt these 
    regulations is specified in Sec. 271.21(e). This deadline can be 
    extended in certain cases (see Sec. 271.21(e)(3)). Once EPA approves 
    the modification, the State requirements become Subtitle C RCRA 
    requirements.
        States with authorized RCRA programs may already have requirements 
    similar to those in today's rule. These State regulations have not been 
    assessed against the Federal regulations being proposed today to 
    determine whether they meet the tests for authorization. Thus, a State 
    is not authorized to implement these requirements in lieu of EPA until 
    the State program modifications are approved. Of course, states with 
    existing standards could continue to administer and enforce their 
    standards as a matter of State law. In implementing the Federal 
    program, EPA will work with States under agreements to minimize 
    duplication of efforts. In most cases, EPA expects that it will be able 
    to defer to the States in their efforts to implement their programs 
    rather than take separate actions under Federal authority.
        States that submit official applications for final authorization 
    less than 12 months after the effective date of these regulations are 
    not required to include standards equivalent to these regulations in 
    their application. However, the State must modify its program by the 
    deadline set forth in Sec. 271.21(e). States that submit official 
    applications for final authorization 12 months after the effective date 
    of these regulations must include standards equivalent to these 
    regulations in their application. The requirements a State must meet 
    when submitting its final authorization application are set forth in 40 
    CFR 271.3.
    
    IX. Regulatory Requirements
    
    A. Regulatory Impact Analysis Pursuant to Executive Order 12866
    
        Executive Order No. 12866 requires agencies to determine whether a 
    regulatory action is ``significant.'' The Order defines a 
    ``significant'' regulatory action as one that ``is likely to result in 
    a rule that may: (1) have an annual effect on the economy of $100 
    million or more or adversely affect, in a material way, the economy, a 
    sector of the economy, productivity, competition, jobs, the 
    environment, public health or safety, or State, local, or tribal 
    governments or communities; (2) create serious inconsistency or 
    otherwise interfere with an action taken or planned by another agency; 
    (3) materially alter the budgetary impact of entitlements, grants, user 
    fees, or loan programs or the rights and obligations of recipients; or 
    (4) raise novel legal or policy issues arising out of legal mandates, 
    the President's priorities, or the principles set forth in the 
    Executive Order.''
        The Agency estimated the costs of today's rule to determine if it 
    is a significant regulation as defined by the Executive Order. The 
    analysis considers compliance cost and economic impacts for both 
    characteristic wastes and newly listed wastes affected by this rule. 
    For characteristic wastes, the potential cost impacts of this rule 
    depend on whether facilities' current wastewater treatment systems will 
    meet the UTS levels or if additional treatment will be required. If 
    current treatments are adequate, facilities will only incur 
    administrative costs to have their permits revised as well as on-going 
    monitoring costs. In general, the Agency expects that facilities will 
    seek permit modifications, treatability variances, or certification of 
    adequate POTW treatment because these compliance options can be 
    implemented at much lower cost than the option requiring treatment to 
    UTS levels. EPA estimates the total annualized costs of the rule for 
    these wastes would range from approximately $197,000 to $598,000, of 
    which $154,000 to $425,000 would be incurred at the 28 to 73 
    potentially affected facilities in the organic chemical industry, and 
    approximately $43,000 to $173,000 would be incurred at the 8 to 30 
    potentially affected facilities in the petroleum refining industry. 
    However, at the high end, if current wastewater treatment systems need 
    to be augmented with additional treatment steps, the incremental 
    compliance costs for today's rule could be as high as $1 million per 
    affected facility. The Agency does not have adequate data to estimate 
    how many, if any, facilities may require modification to their 
    treatment facilities. The Agency did conduct a sensitivity analysis, 
    considering the costs of the rule under two scenarios: (1) Assuming 
    that 80 percent of the facilities comply with the rule by obtaining 
    permit modifications and 20 percent comply by treating their wastes, 
    and, (2) assuming that 60 percent comply by obtaining permit 
    modifications and 40 percent comply by treating their wastes. Based on 
    the first scenario, the estimated annualized costs of the rule would 
    range from $6.6 million to $18.2 million. Based on the second scenario, 
    the estimated annualized costs would range from $12.9 million to $35.7 
    million. For newly listed wastes, the costs are substantially higher 
    and will be incurred each year. These costs range from approximately 
    $11.9 million to $47.3 million and are attributable to thermal 
    treatment of aluminum potliner wastes (K088). Therefore, today's rule 
    may be considered an economically significant rule. Because today's 
    rule is significant, the Agency analyzed the costs, economic impacts, 
    and benefits.
        This section of the preamble for today's rule provides a discussion 
    of the methodology used for estimating the costs, economic impacts and 
    the benefits attributable to today's rule, followed by a presentation 
    of the cost, economic impact and benefit results. More detailed 
    discussions of the methodology and results may be found in the 
    background document, ``Regulatory Impact Analysis of the Land Disposal 
    Restrictions Final Rule for the LDR Phase III Newly Listed and 
    Identified Wastes,'' which has been placed in the docket for today's 
    rule.
    1. Methodology Section
        In today's rule, the Agency is establishing treatment standards for 
    the following wastes: end-of-pipe standards for ignitable, corrosive, 
    and reactive (ICR) wastewaters managed in CWA, CWA-equivalent systems, 
    and UIC wells; Toxicity Characteristic pesticide (D012-17) and organic 
    (D018-43) wastewaters managed in CWA, CWA-equivalent systems, and UIC 
    wells; and newly listed wastes from two industries--spent aluminum 
    potliners and carbamates.
        a. Methodology for Estimating the Affected Universe. In determining 
    the costs, economic impacts, and benefits associated with today's rule, 
    the Agency
    
    [[Page 15592]]
    estimated the volumes of waste affected by today's rule. The procedure 
    for estimating the volumes of ICR waste and TC organic and pesticide 
    waste, and newly listed wastes affected by today's rule is summarized 
    below.
        First, the Agency examined all industries which might be likely to 
    produce wastes covered under today's standards. Through reviewing 
    comments to the Supplemental Notice of Data Availability published by 
    the Agency in 1993, reviewing runs from the Biennial Reporting System 
    (BRS) of volumes generated from particular industry sectors, as well as 
    discussions with industry, and discussions with the Office of Water at 
    EPA HQ, the Agency narrowed it down to 16 industries which would 
    potentially have significant volumes of wastewater affected by today's 
    rule.
        Using a host of databases and/or sources, the Agency collected data 
    on the quantities, constituents, and concentrations of the volumes 
    affected from each of the 16 industries. In addition, the Agency 
    gathered any data on current management practices, plant design, etc. 
    The following sources were used: Toxic Release Inventory (TRI), Section 
    308 data from the Office of Water, Industrial Studies Database (ISDB), 
    1991 Biennial Reporting System (BRS), primary summary and development 
    documents data from effluent guidelines, TCRIA documents, data gathered 
    in the capacity analysis performed for today's rule, as well as 
    comments from potentially affected industries.
        The Agency obtained volume information for the newly listed 
    wastes--spent aluminum potliners (K088) and carbamate wastes (K156-
    161)--from the listing documents prepared for these wastes during the 
    listing procedure.
        b. Cost Methodology. The cost analysis estimates the national level 
    incremental costs which will be incurred as a result of today's rule. 
    The cost estimates for both the baseline and post-regulatory scenarios 
    are calculated employing: (i) the facility wastestream volume, (ii) the 
    management practice (baseline or post-regulatory) assigned to that 
    wastestream, and (iii) the unit cost associated with that practice. 
    Summing the costs for all facilities produces the total costs for the 
    given waste and scenario. Subtracting the baseline cost from the post-
    regulatory cost produces the national incremental cost associated with 
    today's rule for the given waste.
        The cost methodology section includes three sub-sections: (i) ICR 
    and TC Pesticide and Organic Wastes Managed in CWA and CWA-Equivalent 
    Systems, (ii) Newly Listed Wastes, (iii) Testing and Recordkeeping 
    Costs.
        i. ICR and TC Pesticide and Organic Wastes Managed in CWA and CWA-
    Equivalent Systems. The Agency employed the following approach to 
    estimate the incremental costs for the ICR and TC wastes. First, using 
    information available on the affected industries, the Agency created 
    average-sized model facilities for each industry. Second, for a given 
    model facility in an affected industry, the Agency used available unit 
    cost data to develop costs for the baseline management practices 
    (usually treatment in surface impoundments followed by discharge into 
    receiving waters through a NPDES permit). Third, the Agency used data 
    on the constituents and waste quantities for each industry, where 
    applicable, to determine the necessary treatment required to reduce to 
    UTS levels the constituents present. Fourth, the Agency used unit costs 
    to develop costs for the post-regulatory management practices for the 
    treatment requirements determined in the third step. Fifth, subtracting 
    the baseline from the post-regulatory costs for an average facility in 
    an industry sector and using the data available on the number of 
    facilities affected within each industry, the Agency was able calculate 
    the incremental cost for a given industry. Sixth, summing costs across 
    affected industries, the Agency determined the incremental cost for the 
    rule for the end-of-pipe treatment standards.
        ii. Newly Listed Wastes. The costs for treatment of spent aluminum 
    potliners (K088) and carbamate wastes (K156-161) will be determined 
    using data from the listings on baseline management practices, judgment 
    on the technology(s) required to meet the UTS standards for these 
    wastes, and available unit cost data.
        iii. Testing and Recordkeeping Costs. Testing and recordkeeping 
    costs, including costs that facilities will incur for ensuring that 
    hazardous constituents in characteristic waste are meeting new 
    treatment standards and costs associated with permit modifications will 
    be based upon an average, one-time testing cost, on-going monitoring 
    costs, and an Information Collection Request, respectively.
        c. Economic Impact Methodology. The economic effects of today's 
    rule are defined as the difference between the industrial activity 
    under post-regulatory conditions and the industrial activity in the 
    absence of regulation (i.e., baseline conditions).
        The Agency used (1) historic average capital expenditures for each 
    industry, (2) historic average operating expenditures for each 
    industry, (3) historic revenues, and (4) historic average pollution 
    abatement and control expenditures (PACE) to determine the economic 
    impacts. However, the Agency was unable to examine the impacts on a 
    facility-specific basis due to lack of data. Therefore, the impacts are 
    assessed on an industry-specific basis.
        d. Benefits Methodology. The approach for estimating benefits 
    associated with today's rule involves three components: (i) estimation 
    of pollutant loadings reductions, (ii) estimation of reductions in 
    exceedances of health-based levels, and, (iii) qualitative description 
    of the potential benefits. The benefits assessment is based upon the 
    waste quantity and concentration data collected for the cost analysis. 
    This incremental assessment focuses upon reductions in toxic 
    concentrations at the point of discharge and does not consider any 
    potential benefits resulting from reductions in air emissions or 
    impacts on impoundment leaks and sludges which may occur as part of 
    treating wastes to comply with the LDRs. It is expected that additional 
    treatment to comply with the LDRs may result in risk reductions from 
    air emissions, leaks, and sludges.
        EPA has conducted an assessment of the benefits related to the 
    effects of the rule on newly listed spent aluminum potliners. These 
    benefits depend on the incremental risk reductions that may result from 
    treatment of the wastes. In conducting the risk assessment for spent 
    aluminum potliners, EPA improved upon the fate and transport modeling 
    approach used in the RIA. Specifically, in the RIA, EPA applied generic 
    dilution/attenuation factors (DAFs) (which did not reflect constituent-
    specific fate and transport processes, site-specific hydrogeological 
    conditions, or waste characterization data) to relate the concentration 
    of contaminants in the leachate to their concentration in a down-
    gradient well. Instead, EPA used its Composite Model for Leachate 
    Migration and Transformation Products (EPACMTP) to perform constituent-
    specific fate and transport modeling. A summary of the analysis can be 
    found in the Addendum to the RIA placed in the docket for this rule. 
    EPA data indicate that approximately 120,000 metric tons of spent 
    aluminum potliners are generated annually. EPA has not conducted an 
    assessment of the benefits related to the effects of the rule on newly 
    listed carbamate wastes. Because the Agency expects facilities to 
    comply with LDRs through permit modifications, and because the quantity 
    of waste is very small, benefits for
    
    [[Page 15593]]
    newly listed carbamate wastes are expected to be minimal.
        i. Estimation of Pollutant Loadings Reductions. An incremental 
    approach was used to estimate reductions in pollutant loadings. For the 
    baseline scenario, contaminant concentrations were based upon data or 
    estimates of current effluent discharge concentration levels. For the 
    post-regulatory scenario, concentration levels were assumed to equal 
    UTS levels.
        ii. Estimation of Reductions in Exceedances of Health-Based Levels. 
    The methods used for evaluating the benefits associated with cancer and 
    noncancer risk reductions resulting from the rule entail comparing 
    constituent concentration levels to health-based standards to evaluate 
    whether implementation of the rule reduces concentration levels below 
    levels that pose risk to human health.
        To estimate benefits from cancer risk reductions resulting from the 
    rule, a simple screening analysis was performed. This analysis compared 
    contaminant concentrations for the baseline and post-regulatory 
    scenario to health-based levels for carcinogens. Further analysis may 
    be undertaken to quantify benefits associated with facility/ 
    wastestream combinations identified in the contaminant concentration 
    comparisons.
        Benefits associated with reductions in non-cancer exceedances are 
    estimated based upon comparisons of contaminant concentration levels in 
    effluent discharges of the affected wastestreams to the reference 
    health levels. These benefits are expressed in terms of the number of 
    exceedances of health-based levels under the baseline scenario compared 
    to the number of exceedances under the rule.
        iii. Qualitative Description of the Potential Benefits. A 
    qualitative assessment of potential benefits likely to result from the 
    rule is used where data are limited. The Agency acknowledges limited 
    data availability in developing waste volumes affected, constituents, 
    concentrations, cost estimates, economic impacts, and benefits 
    estimates for the LDR Phase III rulemaking. The Agency continues to 
    request comment from industry regarding constituents, concentrations, 
    waste volumes, and current management practices.
    2. Results
        a. Volume Results. The Agency has estimated the volumes of formerly 
    characteristic wastes potentially affected by today's rule to total in 
    the range of 33.5 to 500 million metric tons. The Agency requests 
    comment on waste volumes affected by the LDR Phase III rule. For newly 
    listed wastes, the analyses supporting the listing determination showed 
    about 4,500 metric tons of carbamate wastes and 118,000 metric tons of 
    spent aluminum potliners are potentially affected by this rule.
        b. Cost Results. For characteristic wastes, the potential cost 
    impacts of this rule depend on whether facilities' current wastewater 
    treatment systems will meet the UTS levels or if additional treatment 
    will be required. If current treatments are adequate, facilities will 
    only incur administrative costs to have their permits revised. EPA 
    estimates the total annualized costs of the rule for these wastes would 
    range from approximately $197,000 to $598,000, of which $154,000 to 
    $425,000 would be incurred at the 28 to 73 potentially affected 
    facilities in the organic chemical industry, and approximately $43,000 
    to $173,000 would be incurred at the 8 to 30 potentially affected 
    facilities in the petroleum refining industry. However, at the high 
    end, if current wastewater treatment systems need to be augmented with 
    additional treatment steps, the incremental compliance costs could be 
    as high as $1 million per affected facility. The Agency does not have 
    adequate data to estimate how many, if any, facilities may require 
    modification to their treatment facilities. The Agency continues to 
    request comment and data on how often additional treatment may be 
    required.
        For newly listed wastes, the costs are substantially higher and 
    will be incurred each year. These costs range from approximately $11.9 
    million to $47.3 million and are attributable to thermal treatment of 
    aluminum potliner wastes (K088). The Agency requests comment on where 
    industry falls within this range.
        c. Economic Impact Results. The Agency has estimated the economic 
    impacts of today's rule to represent less than one percent of historic 
    pollution control and operating costs for the organic chemical and 
    petroleum refining industries. However, for those facilities that may 
    need to treat to UTS to comply with today's rule, costs could be more 
    significant. The estimated compliance costs for treating newly listed 
    spent aluminum potliners represents 40 percent of pollution control 
    operating costs for aluminum reducers; however, treatment costs 
    represent only one percent of total historic operating costs.
        d. Benefit Estimate Results. The Agency expects facilities to 
    comply with the LDRs through permit modifications. As a result, the 
    Agency has estimated the benefits associated with today's rule to be 
    small. Assuming facilities comply with the rule by treating their 
    affected wastestreams, loadings reductions estimates range between 
    1,527 to 21,322 metric tons per year at 129 to 291 facilities (direct 
    and indirect dischargers) involving 175 to 647 constituent/wastestream 
    combinations. Ninety-eight percent of the reductions occur at organic 
    chemicals facilities, with the remainder occurring at petroleum 
    refiners. Estimated loadings reductions for direct dischargers range 
    between 36 and 267 tons per year, representing between 0.03 and 0.2 
    percent of total Toxic Release Inventory (TRI) chemical loadings to 
    surface waters. For indirect dischargers, estimated loadings reductions 
    range between 1,491 and 21,055 metric tons per year, representing 
    between 0.8 and 11.0 percent of total TRI chemical loadings transferred 
    to POTWs. Based upon the results of the screening and more detailed 
    risk assessments, the estimated baseline risks associated with nine to 
    twenty wastestreams (out of the 155 to 404 constituent/wastestream 
    combinations potentially affected by the rule) exceed 10-6 under 
    baseline conditions and three to six wastestreams with noncancer risk 
    levels exceeding reference doses. These 12 to 26 wastestreams contain 
    one of five constituents: aniline (9 to 19 wastestreams), acrylamide (0 
    to 1 wastestream), pyridine (2 waststreams), barium compounds (1 
    wastestream), and acetonitrile (0 to 2 wastestreams). For these 12 to 
    26 wastestreams, EPA conducted a more detailed risk assessment, using 
    site-specific data. Results of the more detailed risk assessment 
    indicate that the benefits from the rule are small. EPA identified four 
    wastestreams potentially posing cancer risk exceeding the threshold 
    risk levels. Three wastestreams pose baseline cancer risk ranging from 
    1  x  10-5 to 1  x  10-4 (due to exposure to aniline) which 
    potentially would be reduced to between 8  x  10-8 and 3  x  
    10-6 under the LDR Phase III rule. A fourth wastestream containing 
    acrylamide poses baseline cancer risk at a level of 2  x  10-3. 
    The rule is estimated to reduce this risk to between 2  x  10-4 
    and 4  x  10-36. All four of these wastestreams are discharged to 
    POTWs; if POTW treatment removes these constituents from the wastewater 
    prior to discharge to surface water and/or if no drinking water intake 
    is located downstream from the POTW's outfall, baseline risks will be 
    lower. The Agency expects facilities to comply with the LDRs through 
    permit modifications;
    
    [[Page 15594]]
    however, additional treatment may result in potentially significant 
    risk reduction.
        EPA performed constituent-specific fate and transport modeling 
    using its EPACMTP to further assess cancer and noncancer risks of spent 
    aluminum potliners. Using these additional data, EPA assessment of 
    baseline risks indicates that individual lifetime cancer risks increase 
    to about 10-6 under central tendency assumptions and 10-3 
    under high-end assumptions. In addition, the new estimates suggest that 
    under high-end assumptions, baseline concentrations in drinking water 
    may be high enough to present noncancer risks; previously, noncancer 
    risks were estimated to be negligible. Consequently, the benefits of 
    regulating spent aluminum potliners are higher than previously 
    estimated. Under central tendency assumptions, individual lifetime 
    cancer risks resulting from current waste management practices are 
    slightly higher than post-regulatory risks (10-6 versus less than 
    10-6); some incremental benefits may therefore be realized as a 
    result of the LDRs. Under high-end assumptions, however, the regulation 
    could reduce cancer risks by one or two order of magnitude, while 
    noncancer risks could be eliminated. Although population risks would 
    also be reduced correspondingly, EPA is unable to specify the magnitude 
    of the exposed population.
    
    B. Regulatory Impact Analysis for Underground Injected Wastes
    
        The Agency has completed a separate regulatory impact analysis for 
    underground injected wastes affected by the LDR Phase III final rule. 
    This analysis describes the regulatory impacts only to the Class I 
    injection well universe. The new Phase III LDRs cover decharacterized 
    ICR and TC organic wastes, and other newly-identified hazardous wastes 
    that are distinctly industrial wastes injected by owners and operators 
    of only Class I hazardous and non-hazardous injection wells.
        According to the available data outlined in the RIA, our best 
    estimate indicates that of the 223 Class I injection facilities in the 
    nation, up to 154 facilities will be affected by the new Phase III 
    LDRs. Of these facilities, 100 inject nonhazardous waste and 54 inject 
    hazardous waste. Combined, these facilities inject approximately 18 
    billion gallons of waste annually into Class I wells. These Class I 
    injection wells will now be required to either treat wastes onsite, 
    segregate and ship affected wastes offsite for treatment and disposal, 
    or file no migration petitions as outlined in the UIC regulations in 40 
    CFR Part 148 (See 53 FR 28118, July 26, 1988, preamble for a mote 
    thorough discussion of the no migration petition review process). 
    Additional options for compliance with the final Phase III LDRs, 
    including a de minimis exemption and a pollution prevention option 
    discussed in detail elsewhere in this rule and in the final UIC RIA.
        Of the newly affected Class I facilities, 38 already have no 
    migration exemptions approved by EPA, but they may be required to 
    submit a petition modification to EPA due to the Phase III rule unless 
    their original petition already addressed affected Phase III wastes, 
    including underlying hazardous constituents in decharacterized wastes. 
    In the cases where the petition already covers all hazardous wastes and 
    underlying hazardous constituents in the injected waste stream (i.e., 
    the injectate that was evaluated during the no migration petition 
    process has not changed), no further Agency review of these petitions 
    is necessary. For the facilities which do not have approved no 
    migration exemptions, the rule will add compliance costs to those 
    incurred as a result of previous rulemakings. The Agency analyzed costs 
    and benefits for the final Phase III rule using the same approach and 
    methodology developed in the Regulatory Impact Analysis of the 
    Underground Injection Control Program: Proposed Hazardous Waste 
    Disposal Injection Restriction (53 FR 28118) and subsequent LDR 
    rulemaking. An analysis was performed to assess the economic effect of 
    associated compliance costs for the additional volumes of injected 
    wastes attributable to this rule.
        In general, Class I injection facilities affected by the LDR Phase 
    III rule have several options. As previously outlined, some facilities 
    will modify existing no migration petitions already approved by the 
    Agency, others may submit entirely new petitions, and still others may 
    accept the prohibitions and either continue to inject treated wastes or 
    cease injection operations altogether. And some facilities with 
    approved petitions already addressing Phase III wastes will have no or 
    little additional compliance costs. EPA assessed compliance costs for 
    Class I facilities submitting no migration petitions, employing 
    alternative treatment, and/or implementing pollution prevention 
    measures. Although facilities using pollution prevention/waste 
    minimization to comply with the Phase III LDRs will likely lower 
    overall regulatory compliance costs, these situations are site-specific 
    and, therefore, EPA cannot estimate these costs savings at this time.
        For Class I facilities opting to use alternative treatment, the 
    Agency derived costs for both treating wastes on-site, and/or shipping 
    wastes and treating them off-site at a commercial facility. However, 
    EPA believes that the segregation and transportation of large volumes 
    of liquid wastes off-site is not very practical or cost-effective. This 
    makes the off-site treatment scenario, at best, a highly conservative 
    analysis and in actuality, a least likely and therefore discountable 
    scenario. EPA expects that all injection facilities will opt for the 
    most cost-effective approach in complying with the Phase III final rule 
    and they will either submit a no migration petition or treat their 
    wastes on-site. EPA also assumes that non-commercial facilities will 
    segregate wastes for treatment on-site, whereas commercial facilities 
    will find it more cost effective to not segregate LDR Phase III wastes. 
    For the final rule, EPA estimates that the total annual compliance cost 
    for petitions and alternative on-site treatment to industry affected by 
    the new LDR Phase III prohibitions will range between $32.91 million to 
    $34.08 million per year. The average annual compliance costs per 
    affected facility employing on-site alternative treatment were 
    $217,500. The range of costs for alternative treatment is the result of 
    applying a sensitivity analysis. Only the incremental treatment costs 
    for the new waste listings are calculated in this RIA. All of these 
    costs will be incurred by Class I injection well owners and operators. 
    The average annual compliance costs per affected facility employing on-
    site alternative treatment were $217,500. The total annual compliance 
    costs for the 154 potentially affected facilities would therefore be 
    $33.4 million. These figures were derived by applying the probability 
    of certain outcomes occurring, via the decision tree methodology 
    described in the RIA, to the costs associated with those outcomes for 
    each affected facility.
        Additionally, as part of the RIA analysis, the costs associated 
    with three differing scenarios also were derived. These scenarios are 
    represented by (1) a minimum case, where all facilities incur only 
    petition costs, (2) a mid-line case, where all facilities incur 
    treatment costs (commercial facilities treat on-site with no waste 
    segregation while non-commercial facilities chose the least cost 
    treatment option), and a maximum case, where all facilities incur both 
    petition and treatment costs. Costs associated with these scenarios 
    range
    
    [[Page 15595]]
    from $3.67 million per year for all facilities incurring only petition 
    costs to $132.62 million per year for all facilities incurring both 
    petition and treatment costs. Based on past EPA experience, there is 
    little probability that all facilities will arrive at each of these 
    possible outcomes. However, this indicated range provides an extreme 
    lower and upper bound estimate for national compliance costs purposes.
        The benefits to human health and the environment in the RIA are 
    generally defined as reduced human health risk resulting from fewer 
    instances of ground water contamination. In general, potential health 
    risks from Class I injection wells are extremely low.
        EPA conducted a quantitative assessment of the potential human 
    health risks associated with two well malfunction scenarios. EPA 
    developed a methodology described in the RIA to measure health risks of 
    five Phase III contaminants: benzene, carbon tetrachloride, chloroform, 
    phenol, and toluene. The results of these analyses show that most of 
    the cancer risks calculated are below the 1  x  10-4 to 1  x  
    10-6 risk range generally used by EPA to regulate exposure to 
    carcinogens. Virtually all of the non-cancer risks are below a hazard 
    index (HI) of 1, which represents a ratio used to compare the relative 
    health risks posed by contaminants. Therefore, these cancer and non-
    cancer risks calculated are below any levels of regulatory concern. 
    Only two cancer risk estimates in the high end scenarios, those 
    calculated for benzene and carbon tetrachloride, slightly exceeded the 
    risk range to regulate exposure to carcinogens. Only one hazard index 
    calculated for carbon tetrachloride exceeded EPA's level of concern of 
    a ratio greater than 1. However, these results were derived from a 
    scenario where an abandoned borehole (i.e. the ``failure pathway'') was 
    in very close proximity to the injection well, substantial pumping of a 
    drinking water well was occurring, and the local geology was typical of 
    the highly transmissive East Gulf Coast Region. The assumptions used in 
    deriving these results were based on conservative, upper-bound 
    estimates, therefore the cancer and non-cancer risks represent worst-
    case estimates. Considering the limitations imposed by the failure 
    scenarios, and the documented low probability of Class I failures, the 
    overall risks from failure of Class I injection wells would be below 
    regulatory concern.
        There also is a potential qualitative benefit to the no-migration 
    process for Class I nonhazardous wells. It is possible that the process 
    would uncover certain wells that cannot satisfy the no-migration 
    standard and indeed may not be suitable for Class I injection in any 
    case. This proved to be true for Class I hazardous wells. However, 
    notwithstanding this potential benefit, as noted in the early part of 
    this preamble, the Agency does not regard this regulatory effort as 
    deserving of the priority afforded it, due to the litigation-driven 
    schedule and the D.C. Circuit's mandate, and would not be undertaking 
    the effort at this time were it not for that mandate and schedule.
        The economic analysis of LDR Phase III compliance costs suggests 
    that publicly traded companies probably will not be significantly 
    affected. The limited data available for privately-held companies 
    suggests, however, that they may face significant costs due to the 
    proportionally larger expenses they may face due to the LDR Phase III 
    rule.
    
    C. Regulatory Flexibility Analysis
    
        Pursuant to the Regulatory Flexibility Act of 1980, 5 U.S.C. 601 et 
    seq., when an agency publishes a notice of rulemaking, for a rule that 
    will have a significant effect on a substantial number of small 
    entities, the agency must prepare and make available for public comment 
    a regulatory flexibility analysis that considers the effect of the rule 
    on small entities (i.e.: small businesses, small organizations, and 
    small governmental jurisdictions). Under the Agency's Revised 
    Guidelines for Implementing The Regulatory Flexibility Act, dated May 
    4, 1992, the Agency committed to considering regulatory alternatives in 
    rulemakings when there were any economic impacts estimated on any small 
    entities. (See RCRA sections 3004 (d), (e), and (g)(5), which apply 
    uniformly to all hazardous wastes.) Previous guidance required 
    regulatory alternatives to be examined only when significant economic 
    effects were estimated on a substantial number of small entities.
        In assessing the regulatory approach for dealing with small 
    entities in today's rule, for both surface disposal of wastes, the 
    Agency considered two factors. First, data on potentially affected 
    small entities are unavailable. Second, due to the statutory 
    requirements of the RCRA LDR program, no legal avenues exist for the 
    Agency to provide relief from the LDR's for small entities. The only 
    relief available for small entities is the existing small quantity 
    generator provisions and conditionally exempt small quantity generator 
    exemptions found in 40 CFR 262.11-12, and 261.5, respectively. These 
    exemptions basically prescribe 100 kilograms (kg) per calendar month 
    generation of hazardous waste as the limit below which one is exempted 
    from complying with the RCRA standards.
        Given these two factors, the Agency was unable to frame a series of 
    small entity options from which to select the lowest cost approach; 
    rather, the Agency was legally bound to regulate the land disposal of 
    the hazardous wastes covered in today's rule without regard to the size 
    of the entity being regulated.
        The Agency has, however, included an exemption covering injection 
    facilities where the decharacterized portion of the injectate is 
    minimal in absolute terms, as a percentage of the total injectate, and 
    in hazardous constituent mass loadings. This de minimis exemption 
    provides a measure of relief to both small and larger entities 
    satisfying its terms.
    
    D. Paperwork Reduction Act
    
        The information collection requirements in this rule have been 
    submitted for approval to the Office of Management and Budget (OMB) 
    under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. Four 
    Information Collection Request (ICR) documents have been prepared by 
    EPA, as follows. OSWER ICR No. 1442.12 would amend the existing ICR 
    approved under OMB Control No. 2050-0085. The additional information 
    requirements for the Underground Injection Control (UIC) Program were 
    submitted to OMB under ICR No. 0370.14; this will amend the existing 
    UIC approval under OMB Control No. 2040-0042. OSWER ICR No. 1442.12 and 
    UIC ICR No. 0370.14 have not been approved by OMB and the information 
    collection requirements in those ICRs are not enforceable until OMB 
    approves them. EPA will publish a document in the Federal Register when 
    OMB approves the information collection requirements. Until EPA 
    publishes a document displaying the valid OMB control number, persons 
    are not required to respond to collections of information in these two 
    ICRs. Two amendments to National Pollutant Discharge Elimination System 
    (NPDES) ICRs were approved at proposal. These are ICR 0229.10 for the 
    Discharge Monitoring Report, approved under OMB Control No. 2040-0004, 
    and ICR 0226.11 for NPDES Applications, approved under OMB Control No. 
    2040-0086.
        Copies of these ICRs may be obtained from Sandy Farmer, OPPE 
    Regulatory Information Division; U.S. Environmental Protection Agency 
    (2136); 401 M St., S.W.; Washington, D.C. 20460 or by calling (202) 
    260-2740. Include the ICR numbers in any request. The information 
    requirements for the
    
    [[Page 15596]]
    OSWER ICR and the UIC ICR are not effective until OMB approves them.
        The additional burden associated with the OSWER ICR 1442.12 is as 
    follows. The overall annual burden for the recordkeeping and reporting 
    requirements is 4,202 hours. It is expected that approximately 125 
    respondents will be affected, therefore, the annual recordkeeping and 
    reporting burden averages 33 hours per respondent. This time is 
    necessary to collect data, submit notifications and certifications to 
    waste treaters and disposers, and to maintain records of this 
    information. The annual cost burden for this rule is approximately 
    $177,045. Of this amount, it is estimated that facilities will incur 
    annual operation and maintainence capital costs of approximately 
    $8,375.
        The additional burden associated with the UIC Program, explained in 
    ICR 0370.14, is as follows. The estimated annual reporting burden 
    averages 3845 hours per respondent (i.e., inclusive of incremental 
    reporting burdens associated with all affected Class I facilities and 
    Primacy States). The average incremental annual reporting and 
    recordkeeping burdens are about 4,442 hours per each affected Class I 
    nonhazardous facility and about 2,700 hours per each affected Class I 
    hazardous facility. For efforts associated with implementing the rule 
    amendments, the annual incremental State burden equals about 22 hours 
    for each Class I respondent.
        Burden means the total time, effort, or financial resources 
    expended by persons to generate, maintain, retain, or disclose or 
    provide information to or for a Federal agency. This includes the time 
    needed to review instructions; develop, acquire, install, and utilize 
    technology and systems for the purposes of collecting, validating, and 
    verifying information, processing and maintaining information, and 
    disclosing and providing information; adjust the existing ways to 
    comply with any previously applicable instructions and requirements; 
    train personnel to be able to respond to a collection of information; 
    search data sources; complete and review the collection of information; 
    and transmit or otherwise disclose the information.
        An Agency may not conduct or sponsor, and a person is not required 
    to respond to a collection of information unless it displays a 
    currently valid OMB control number.
        Send comments on the Agency's need for this information, the 
    accuracy of the provided burden estimates, and any suggested methods 
    for minimizing respondent burden, including through the use of 
    automated collection of techniques to the Director, OPPE Regulatory 
    Information Division; U.S. Environmental Protection Agency (2136); 401 
    M St., S.W.; Washington, DC 20460; and to the Office of Information and 
    Regulatory Affairs, Office of Management and Budget, 725 17th St.,

    X. Unfunded Mandates Reform Act
    
        Under Section 202 of the Unfunded Mandates Reform Act of 1995, 
    signed into law on March 22, 1995, EPA must prepare a statement to 
    accompany any rule where the estimated costs to State, local, or tribal 
    governments in the aggregate, or to the private sector, will be $100 
    million or more in any one year. Under Section 205, EPA must select the 
    most cost-effective and least burdensome alternative that achieves the 
    objective of the rule and is consistent with statutory requirements. 
    Section 203 requires EPA to establish a plan for informing and advising 
    any small governments that may be significantly impacted by the rule.
        EPA has completed an analysis of the costs and benefits from the 
    LDR Phase III rule and has determined that this rule does not include a 
    Federal mandate that may result in estimated costs of $100 million or 
    more to either State, local or tribal governments in the aggregate. As 
    stated above, the private sector may incur costs exceeding $100 million 
    per year depending upon the option chosen in the final rulemaking. EPA 
    has fulfilled the requirement for analysis under the Unfunded Mandates 
    Reform Act, and results of this analysis have been included in the 
    background document ``Regulatory Impact Analysis of the Final Phase III 
    Land Disposal Restrictions Rule,'' which was placed in the docket for 
    today's rule.

        For the reasons set out in the preamble, title 40, chapter I of the 
    Code of Federal Regulations is amended as follows:
    
    PART 148--HAZARDOUS WASTE INJECTION RESTRICTIONS
    
        1. The authority citation for part 148 continues to read as 
    follows:
    
        Authority: Secs. 3004, Resource Conservation and Recovery Act, 
    42 U.S.C. 6901 et seq.
    
        2. Section 148.1 is amended by revising paragraphs (a), (b) and (d) 
    to read as follows:
    
    
    Sec. 148.1  Purpose, scope and applicability.
    
        (a) This part identifies wastes that are restricted from disposal 
    into Class I wells and defines those circumstances under which a waste, 
    otherwise prohibited from injection, may be injected.
        (b) The requirements of this part apply to owners or operators of 
    Class I hazardous waste injection wells used to inject hazardous waste; 
    and, owners or operators of Class I injection wells used to inject 
    wastes which once exhibited a prohibited characteristic of hazardous 
    waste identified in 40 CFR part 261, subpart C, at the point of 
    generation, and no longer exhibit the characteristic at the point of 
    injection.
    * * * * *
        (d) Wastes that are only hazardous because they display a 
    characteristic of ignitability, corrosivity, reactivity, or toxicity 
    that are otherwise prohibited, are not prohibited:
        (1) If the wastes are disposed into a nonhazardous waste injection 
    well defined under 40 CFR 144.6(a); and
        (2) Do not exhibit any prohibited characteristic of hazardous waste 
    identified in 40 CFR part 261, subpart C, and either:
        (i) Do not contain any hazardous constituents identified in 40 CFR 
    268.48 at levels greater than the 40 CFR 268.48 Universal Treatment 
    Standard levels at the point of generation;
        (ii) Are de minimis in volume and hazardous constituent 
    concentration levels, as defined in 40 CFR 268.1(e)(4)(ii). 
    (Recordkeeping requirements for this alternative are found at 40 CFR 
    268.9(d)(4).); or
        (iii)(A) The facility removes an equivalent mass of hazardous
    
    [[Page 15597]]
    constituents as would be removed by treating the characteristic 
    hazardous wastestream pursuant to the treatment standards in 40 CFR 
    268.48. This mass reduction can come from:
        (1) Treating nonhazardous portions of the injectate;
        (2) Recycling before ultimate injection; or
        (3) Engaging in pollution prevention practices (such as equipment 
    or technology modifications, substitution of raw materials, and 
    improvements in housekeeping, maintenance, training, or inventory 
    control).
        (B) The compliance alternative in paragraph (d)(2)(iii)(A) of this 
    section is demonstrated by comparing the injected baseline (determined 
    by multiplying the volume/day of characteristically hazardous waste 
    generated and injected) times the concentration of hazardous 
    constituents before the treatment/recycling/pollution prevention 
    measure, with the mass allowance obtained by multiplying the volume/day 
    of a hazardous constituent generated and injected times the universal 
    treatment standard for that constituent. The baseline cannot include 
    practices initiated before the year 1990. (Recordkeeping requirements 
    for this alternative are found at 40 CFR 268.9(d)(3).)
        3. Section 148.3 is revised to read as follows:
    
    
    Sec. 148.3  Dilution prohibited as a substitute for treatment.
    
        (a) The provisions of 40 CFR 268.3 shall apply to owners or 
    operators of Class I wells used to inject a waste which is hazardous at 
    the point of generation whether or not the waste is hazardous at the 
    point of injection.
        (b) Owners or operators of Class I nonhazardous waste injection 
    wells which inject waste formerly exhibiting a hazardous characteristic 
    which has been removed by dilution, may address underlying hazardous 
    constituents by treating the hazardous waste, obtaining an exemption 
    pursuant to a petition filed under Sec. 148.20, or complying with the 
    provisions set forth in 40 CFR 268.9.
        4. Section 148.4 is revised to read as follows:
    
    
    Sec. 148.4  Procedures for case-by-case extensions to an effective 
    date.
    
        The owner or operator of a Class I hazardous or nonhazardous waste 
    injection well may submit an application to the Administrator for an 
    extension of the effective date of any applicable prohibition 
    established under subpart B of this part according to the procedures of 
    40 CFR 268.5.
        5. Section 148.18 is added to subpart B to read as follows:
    
    
    Sec. 148.18  Waste specific prohibitions--Newly Identified Wastes.
    
        (a) On July 8, 1996, the wastes specified in 40 CFR 261.32 as EPA 
    Hazardous waste numbers K156-K161, P127, P128, P185, P188-P192, P194, 
    P196-P199, P201-P205, U271, U277-U280, U364-U367, U372, U373, U375-
    U379, U381-387, U389-U396, U400-U404, U407, and U409-U411 are 
    prohibited from underground injection.
        (b) On January 8, 1997, the wastes specified in 40 CFR 261.32 as 
    EPA Hazardous waste number K088 is prohibited from underground 
    injection.
        (c) On April 8, 1998, the wastes specified in 40 CFR part 261 as 
    EPA Hazardous waste numbers D018-043, and Mixed TC/Radioactive wastes, 
    are prohibited from underground injection.
        (d) On April 8, 1998, the wastes specified in 40 CFR part 261 as 
    EPA Hazardous waste numbers D001-D003 are prohibited from underground 
    injection.
        6. Section 148.20 is amended by revising paragraph (a) introductory 
    text to read as follows:
    
    
    Sec. 148.20  Petitions to allow injection of a waste prohibited under 
    subpart B.
    
        (a) Any person seeking an exemption from a prohibition under 
    subpart B of this part for the injection of a restricted hazardous 
    waste, including a hazardous waste exhibiting a characteristic and 
    containing underlying hazardous constituents at the point of 
    generation, but no longer exhibiting a characteristic when injected 
    into a Class I injection well or wells, shall submit a petition to the 
    Director demonstrating that, to a reasonable degree of certainty, there 
    will be no migration of hazardous constituents from the injection zone 
    for as long as the waste remains hazardous. This demonstration requires 
    a showing that:

        (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 Sec. 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:
    
    
    Sec. 268.2  Definitions applicable in this part.
    
    * * * * *
        (f) Wastewaters are wastes that contain less than 1% by weight 
    total organic carbon (TOC) and less than 1% by weight total suspended 
    solids (TSS).
    * * * * *
        (i) Underlying hazardous constituent means any constituent listed 
    in Sec. 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 Sec. 268.3(b)(1), and is specifically listed in 
    appendix XI of this part.
    
    [[Page 15598]]
    
        (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:
    
    
    Sec. 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 Sec. 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 
    Sec. 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;
        (3) The waste, at point of generation, has reasonable heating value 
    such as greater than or equal to 5000 BTU per pound;
        (4) The waste is co-generated with wastes for which combustion is a 
    required method of treatment;
        (5) The waste is subject to Federal and/or State requirements 
    necessitating reduction of organics (including biological agents); or
        (6) The waste contains greater than 1% Total Organic Carbon (TOC).
        11. Section 268.7 is amended by revising the last sentence of 
    paragraph (a) introductory text, paragraphs (a)(1)(ii), (a)(2)(i)(B), 
    (a)(3)(ii), (b)(4)(ii), (b)(5)(iv), by removing ``268.45';'' at the end 
    of paragraph (a)(1)(iv) and adding ``268.45'; and'' in its place, by 
    removing ``; and,'' at the end of paragraph (a)(1)(v) and adding a 
    period in its place, by removing paragraph (a)(1)(vi), and by adding 
    paragraph (b)(5)(v) to read as follows:

    characteristic of ignitability (D001) (and is not in the High TOC 
    Ignitable Liquids Subcategory or is not treated by CMBST or RORGS of 
    Sec. 268.42, Table 1), and/or the characteristic of corrosivity (D002), 
    and/or reactivity (D003), and/or the characteristic of organic toxicity 
    (D012-D043), and is prohibited under Sec. 268.37, Sec. 268.38, and 
    Sec. 268.39, the generator must determine the underlying hazardous

    are: subject to the treatment standards in Sec. 268.40 (other than 
    those expressed as a required method of treatment); that are reasonably 
    expected to contain underlying hazardous constituents as defined in 
    Sec. 268.2(i); are treated on-site to remove the hazardous 
    characteristic; and are then sent off-site for treatment of underlying 
    hazardous constituents, the certification must state the following:
    
        I certify under penalty of law that the waste has been treated 
    in accordance with the requirements of 40 CFR 268.40 to remove the 
    hazardous characteristic. This decharacterized waste contains 
    underlying hazardous constituents that require further treatment to 
    meet universal treatment standards. I am aware that there are 
    significant penalties for submitting a false certification, 
    including the possibility of fine and imprisonment.
    
        (v) For characteristic wastes D001, D002, D003 and D012-D043 that

    Universal Treatment Standards, the certification must state the 
    following:
    
        I certify under penalty of law that the waste has been treated 
    in accordance with the requirements of 40 CFR 268.40 to remove the 
    hazardous characteristic, and that underlying hazardous 
    constituents, as defined in Sec. 268.2, have been treated on-site to 
    meet the Sec. 268.48 Universal Treatment Standards. I am aware that

    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 Sec. 268.42, Table 1), the generator must determine what underlying 
    hazardous constituents (as defined in Sec. 268.2), are reasonably 
    expected to be present above the universal treatment standards found in 
    Sec. 268.48.
    * * * * *
        (d) Wastes that exhibit a characteristic are also subject to 
    Sec. 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 Sec. 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 Sec. 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 Sec. 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 Sec. 268.1, information supporting that 
    qualification must be kept in on-site files.
    
    
    Secs. 268.10-268.12  [Removed and Reserved]
    
        14. Sections 268.10 through 268.12 are removed and reserved.
        15. Section 268.39 is added to subpart C to read as follows:
    
    
    Sec. 268.39  Waste specific prohibitions--End-of-pipe CWA, CWA-
    equivalent, and Class I nonhazardous injection well treatment 
    standards; spent aluminum potliners; and carbamate wastes.
    
        (a) On July 8, 1996, the wastes specified in 40 CFR 261.32 as EPA 
    Hazardous Waste numbers K156-K161; and in 40 CFR 261.33 as EPA 
    Hazardous Waste numbers 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, U407, and U409-U411 are prohibited from 
    land disposal. 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 Sec. 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 Sec. 268.2;
        
    [[Page 15600]]
    
        (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 Sec. 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 Sec. 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 Sec. 268.44;
        (4) Persons have been granted an extension to the effective date of 
    a prohibition pursuant to Sec. 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 
    Sec. 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 Sec. 268.40 to read as follows:
    
    
    Sec. 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 Sec. 268.2(i)) must meet Universal Treatment Standards, found in 
    Sec. 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 
    Sec. 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
        (3) When these wastes are managed in Class I nonhazardous injection 
    wells, compliance with the treatment standards must be achieved no 
    later than the well head; or
        (4) For all other, compliance with the treatment standard must be 
    met prior to land disposal as defined in Sec. 268.2(c).

    Notes to 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
      betweenapplicability 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 it's 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.                                                                                                                                         
    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'', EPA Publication SW-846, as incorporated by reference in 40 CFR 260.11, with a sample size of 10 grams and a distillation time of one hour and 15 minutes.                          
    8 As an alternative to these standards, the underlying hazardous constituents in the waste must meet a CWA limitation, which can include a toxic pollutant indicator for the constituent;       
      Pretreatment Standards for Existing Sources; Pretreatment Standards for New Sources; local limitations based upon a pass-through determination; or a Fundamentally Different Factors variance 
      under 40 CFR 125.30-125.32.

        18. Section 268.44 is amended by revising paragraph (a) to read as 
    follows:
    
    
    Sec. 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 Sec. 268.48.

    \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 and 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 40 CFR part 264, subpart O, or 40 CFR 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.              
    \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'', EPA Publication SW-846,
      as incorporated by reference in 40 CFR 260.11, 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 at Sec.  268.2(i).
