    Clarification of Standards for Hazardous Waste Land Disposal 
    Restriction Treatment Variances
    
    AGENCY: Environmental Protection Agency.
    
    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: EPA is today finalizing clarifying amendments to the rule 
    authorizing treatment variances from the national Land Disposal 
    Restrictions (LDR) treatment standards. The clarifying changes adopt 
    EPA's longstanding interpretation that a treatment variance may be 
    granted when treatment of any given waste to the level or by the method 
    specified in the regulations is not appropriate, whether or not it is 
    technically possible to treat the waste to that level or by that 
    method. In response to comment, the Agency is indicating in the rule 
    the circumstances when application of the national treatment standard 
    could be found to be ``inappropriate'', specifically where the national 
    treatment standard is unsuitable from a technical standpoint or where 
    the national treatment standard could lead to environmentally 
    counterproductive results by discouraging needed remediation.
        In addition, EPA proposed to reissue the treatment variance granted 
    to Citgo Petroleum under the clarified standard. The Agency is not 
    taking further action on this part of the proposal because, due to 
    changes in Citgo's remediation plans for its Lake Charles Louisiana 
    facility, this particular variance has become moot. The Agency is 
    consequently withdrawing the Citgo variance.
    
    EFFECTIVE DATE: These final regulations are effective December 5, 1997.

    I. Background
    
        The essential requirement of the Land Disposal Restrictions (LDR) 
    statutory provisions is that hazardous wastes must not be land disposed 
    until hazardous constituent concentrations in the wastes are at levels 
    at which threats to human health and the environment are minimized, and 
    land disposal is otherwise protective of human health and the 
    environment. RCRA sections 3004 (d), (e), (g) and (m); 56 FR at 41168, 
    August 19, 1991; 62 FR at 26062, May 12, 1997. These requirements 
    normally are satisfied by prohibiting disposal of hazardous wastes 
    until the wastes' hazardous constituent concentrations reflect the 
    performance achievable by the Best Demonstrated Available Treatment 
    technology (BDAT). 62 FR at 26062, May 12, 1997.
        EPA recognized from the inception of the LDR program, however, that 
    there would be circumstances when these technology-based treatment 
    standards might not be either achievable or appropriate. Accordingly, 
    EPA adopted a treatment variance provision (codified in 40 CFR 268.44; 
    51 FR at 40605-40606, Nov. 7, 1986) providing that:
    
        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 the 
    wastes analyzed in developing the treatment standard, the waste 
    cannot be treated to [the] specified levels or by the specified 
    methods.
    
        A treatment variance takes the form of an alternative LDR treatment 
    standard. Nationally applicable variances and site-specific variances 
    that are approved using rulemaking procedures are codified in the Table 
    to Sec. 268.44, 40 CFR 268. 44(o). Site-specific variances that are 
    approved using non-rulemaking procedures are not codified.
        As set out in more detail in the May 12 notice, EPA has interpreted 
    the first sentence of the treatment variance provision as creating two 
    independent tests under which treatment variance applications can be 
    considered: first, where the waste in question cannot be treated to 
    levels or by the methods established in the rules; and second, where 
    such treatment may be possible but is nevertheless ``not appropriate''. 
    62 FR at 26059, May 12, 1997. EPA has further viewed the second 
    sentence of the treatment variance provision--which refers to a 
    demonstration that the waste differs chemically or physically from 
    those the Agency analyzed in developing the standard--as applying only 
    to the technical infeasibility part of the standard. 62 FR at 26059, 
    May 12,
    
    [[Page 64505]]
    
    1997. However, EPA now recognizes that the existing rule, as drafted, 
    might be read to require a demonstration that a waste is physically or 
    chemically different along with a showing that it cannot be treated to 
    a specified level or by a particular method whenever a treatment 
    variance is sought, including situations where the otherwise applicable 
    treatment standard is technically possible but, nonetheless, 
    inappropriate. This was not EPA's intent, and EPA initiated this 
    rulemaking to remove any drafting ambiguity in the rule.
    
    II. Clarified Standard for Granting Treatment Variances
    
        EPA is finalizing the proposed amendment to the rule, with two 
    changes. First, EPA is clarifying the situations under which treatment 
    variances may be approved because the otherwise applicable LDR 
    treatment standard is ``inappropriate.'' Second, the Agency is adding 
    language that explicitly requires alternative LDR treatment standards 
    approved through the treatment variance process to satisfy the 
    requirement that treatment standards result in substantial treatment of 
    hazardous constituents in the waste so that threats posed by the 
    waste's land disposal are minimized, and also indicates that special 
    considerations may arise in satisfying this standard if the waste is to 
    be used in a manner constituting disposal.1
    ---------------------------------------------------------------------------
    
        \1\ EPA is also restoring language to 40 CFR 268.44(a) and (h) 
    that was inadvertently deleted when EPA proposed this clarification 
    and redrafting the introductions to both provisions. These changes 
    are made to restore the inadvertently deleted text and to make the 
    difference between national and site-specific variances more clear, 
    as follows. The 40 CFR 268.44(a) national variance is waste-
    specific--it could apply to the same type of waste at numerous 
    sites. National variances are obtained by petitioning the 
    Administrator and, as set out in 40 CFR 268.44(b), petitions are 
    processed using the procedures set out in 40 CFR 260.20. The 40 CFR 
    268.44(h) variance is site-specific--it applies only to a certain 
    waste generated at a particular site. Site-specific variances are 
    obtained by petitioning the Administrator, or the Administrator's 
    delegated representative, or an authorized state. Petitions for 
    site-specific variances are processed on a site-by-site basis and 
    are not required to be processed using the procedures set out in 40 
    CFR 260.20. Further explanation on this issue is included in the 
    Response to Comments Document for today's action in the response to 
    comments submitted by the Department of Energy. EPA regards the 
    restoration of inadvertently deleted language and the associated 
    clarifications as a technical correction and may, thus, make the 
    changes immediately in this final rule.
    ---------------------------------------------------------------------------
    
    A. Clarification of ``Inappropriate'' Standard
    
        The Agency proposed amended language simply stating that a 
    treatment variance could be granted if it is ``inappropriate'' to 
    require treatment to the level or by the method set out in the rules. 
    62 FR at 26081, May 12, 1997. In the preamble to the proposal, the 
    Agency provided examples as to the situations when application of the 
    otherwise applicable standard could be inappropriate. 62 FR at 26059-
    26060, May 12, 1997. In response to comment maintaining that the rule 
    language was impermissibly open-ended, EPA has decided to include 
    language codifying more particularly when a standard could be 
    ``inappropriate''. These circumstances are drawn from EPA's practice in 
    applying the existing rule and are consistent with the examples 
    discussed in the preambles to the proposal and the HWIR-Media proposal. 
    61 FR at 18810, April 29, 1996.
        The first circumstance is when imposition of BDAT treatment, while 
    technically possible, remains unsuitable or impractical from a 
    technical standpoint. The chief example is when a treatment standard 
    would result in combustion of large amounts of mildly contaminated soil 
    or wastewater. 55 FR at 8760 and 8761, March 8, 1990; 61 FR at 18806-
    18808, April 29, 1996 and other sources cited therein. The same 
    reasoning could apply when media is contaminated with metal 
    contaminants and also contains low levels of organic contaminants. In 
    such a case, it may be inappropriate to require combustion treatment of 
    the organic contaminants both because it may be inappropriate to 
    combust media generally and because it may be inappropriate to combust 
    wastes where metals are the chief hazardous constituent.2 
    Another potential example of where treatment for organic contaminants 
    may be technically inappropriate is when a waste contains low 
    concentrations of non-volatile organic contaminants (for example, 
    concentrations slightly exceeding a Universal Treatment Standard) and 
    the waste, for legitimate reasons, has been stabilized. If the mobility 
    of the non-volatile organic contaminants has been reduced, it might be 
    inappropriate to require further treatment of the non-volatile organic 
    contaminants. Cf. 61 FR at 55724, Oct. 28, 1996 where EPA made a 
    similar finding. Still another example of a situation where the 
    otherwise applicable LDR treatment standard is technically 
    inappropriate could be a case where BDAT treatment could expose site 
    workers to acute risks of fire or explosion and an alternative 
    technology would not. 62 FR at 26060, May 12, 1997. In all these types 
    of circumstances, notwithstanding that it is technically possible to 
    achieve the standard by using the best demonstrated available 
    technology, it could be inappropriate to do so.
    ---------------------------------------------------------------------------
    
        \2\ Although it should also be noted that it is often routine 
    and obviously appropriate to combust organic-contaminated hazardous 
    wastes and to stabilize the combustion residues to reduce metal 
    mobility; see, e.g. treatment standards for F024 wastes in 40 CFR 
    268.40.
    ---------------------------------------------------------------------------
    
        The second set of circumstances where treatment to the limit of 
    best demonstrated available technology might be inappropriate involves 
    cases where imposition of the otherwise applicable treatment standard 
    could result in a net environmental detriment by discouraging 
    aggressive remediation. The example EPA and authorized states have 
    encountered most often to date is where federal rules allow the option 
    of leaving wastes in place,3 and a facility then has the 
    choice of pursuing the legal option of leaving the wastes in place or 
    opting to excavate thereby triggering treatment to standards based on 
    the performance of best demonstrated available technology, which can be 
    very expensive. 62 FR at 26059, May 12, 1997, and other sources there 
    cited.4 In these circumstances, a treatment variance can 
    provide an intermediate option of more aggressive remediation, which 
    may include substantial treatment of the removed waste before disposal 
    of that treatment residue--a net environmental benefit over leaving 
    untreated waste in place. 61 FR at 55720-22, May 12, 1997. In EPA's 
    experience, this situation often occurs when BDAT treatment would 
    require that wastes be treated to achieve constituent concentrations 
    that fall below protective site-specific cleanup levels, thus 
    increasing remediation costs for treatment of excavated wastes. In 
    these instances, EPA has indicated that consideration of a treatment 
    variance is typically warranted (because imposition of the otherwise 
    applicable treatment standard would discourage aggressive remediation 
    and is, therefore, inappropriate) and that, if a variance is approved, 
    protective, site-specific cleanup levels may be used as
    
    [[Page 64506]]
    
    alternative LDR treatment standards. See recent EPA guidance on LDR 
    treatment variances: Jan 8, 1997 memorandum, ``Use of Site-Specific 
    Land Disposal Restriction Treatability Variances Under 40 CFR 268.44(h) 
    During Cleanups'' from Michael Shapiro, Director EPA Office of Solid 
    Waste and Steve Luftig, Director EPA Office of Emergency and Remedial 
    Response and information on compliance with statutory provisions for 
    LDR treatment, below. In addition, see ``Hazardous Waste: Remediation 
    Waste Requirements Can Increase the Time and Cost of Cleanups'' U.S. 
    General Accounting Office, GAO/RCED-98-4, October 1997.
    ---------------------------------------------------------------------------
    
        \3\ Examples are where wastes can remain within an ``area of 
    contamination'', where remedy selection requirements allow a 
    balancing of treatment and containment strategies and where RCRA 
    regulations allow the option of closing a regulated unit with wastes 
    left in place.
        \4\ Another recent example of such a treatment variance was 
    granted to Dow Chemical Co. by EPA Region V. In this case, the 
    company could legally leave wastes within an area of contamination 
    but requested instead that the wastes be exhumed for more secure 
    disposal in a subtitle C landfill. Viewing this as a net 
    environmental benefit, and further finding that no other treatment 
    but combustion was available to reduce the relatively low levels of 
    hazardous constituents (chlorinated dibenzo-dioxins and furans), the 
    Region found the existing treatment requirement inappropriate and 
    granted the variance. Treatment Variance for Dow Chemical Co., June 
    10, 1997, Response to Comment Document pp. 15-17.
    ---------------------------------------------------------------------------
    
        EPA is accordingly codifying qualifying language stating that 
    treatment variances can be granted where the underlying standard is not 
    appropriate either because it is technically inappropriate or because 
    requiring LDR treatment is environmentally inappropriate in that it 
    could discourage aggressive remediation.
        Finally, it must be remembered that this amended rule does not 
    command issuance of treatment variances any more than the existing rule 
    does. Like the existing rules, the amended rules set out circumstances 
    when treatment variances may be considered. The actual determination of 
    whether an otherwise applicable LDR treatment standard is 
    ``unachieveable'' or technically or environmentally ``inappropriate'' 
    is a fact-specific determination depending largely on site-and waste-
    specific circumstances.
    
    B. Compliance With Statutory Provisions for LDR Treatment
    
        As stated in the proposal all treatment variances must be 
    consistent with the root requirement of RCRA section 3004 (m): that 
    treatment be sufficient to minimize threats to human health and the 
    environment posed by land disposal of the waste. See 62 FR at 26060/1, 
    May 12, 1997 (``alternative treatment standards [established by a 
    treatment variance] must comply with the statutory standard of RCRA 
    section 3004(m) by minimizing threats to human health and the 
    environment''). In order to ensure that there is no ambiguity over 
    application of this requirement in the context of alternative LDR 
    treatment standards developed through the treatment variance process, 
    EPA is adding regulatory language that explicitly requires the 
    decision-maker to determine that a revised treatment standard is 
    sufficient to minimize threats posed by land disposal. Cf. 61 FR at 
    55721, October 23, 1996 (finding that alternate standard in treatment 
    variance does minimize threats posed by land disposal). In making this 
    determination, however, EPA (or authorized State) may consider risks 
    posed by land disposal not only of the treated residue, but also the 
    risks posed by the continuation of any existing land disposal of the 
    untreated waste, that is, the risks posed by leaving previously land 
    disposed waste in place. Thus, for example, in a remediation setting, 
    it is appropriate (and likely necessary) to consider risks posed by 
    leaving previously land disposed waste in place as well as risks posed 
    by land disposal of the waste after it is removed and treated. Cf. 61 
    FR at 55721, October 28, 1996 (fact-specific determination that threats 
    posed by land disposal are adequately minimized when treatment variance 
    will lead to clean closure of large surface impoundment, substantial 
    treatment of removed waste, and disposal of treatment residue in a 
    subtitle C landfill) and 61 FR at 18808, April 29, 1996, and other 
    sources cited therein (determination that the policy considerations 
    which argue for BDAT as the basis for technology-based standards for 
    as-generated wastes do not always support a BDAT approach in the 
    remediation context).
        In addition, when making a determination as to whether the 
    statutory provisions for LDR treatment have been satisfied, EPA may, of 
    course, condition any particular variance to apply only in certain 
    circumstances if the facts warrant. There is, at least, one potentially 
    recurring circumstance when such conditioning may be warranted for 
    treatment variances. Under current regulation, hazardous waste-derived 
    products can be used in a manner constituting disposal provided the 
    waste meets the LDR treatment standards. 40 CFR 266.23. The exemption 
    was premised on findings that hazardous wastes would meet requirements 
    reflecting rigorous treatment which typically destroys, removes, or 
    immobilizes hazardous constituents to the limit of available 
    technology. 53 FR at 31198, August 17, 1988. In order to ascertain 
    whether this exemption is still justifiable for wastes which receive 
    treatment variances on the ground that the treatment standard is 
    inappropriate, EPA is noting that as part of a determination of whether 
    threats are minimized under the circumstances, consideration should be 
    given to whether this exemption should continue to apply.5 
    This would entail a fact-specific determination, and notice as to how 
    the determination might be made would have to accompany each such 
    treatment variance. For example, in situations where the decision-maker 
    determines that use of a product derived from hazardous waste in a 
    manner constituting disposal would likely not be adequately protective 
    even if that hazardous waste derived product complied with an 
    alternative land disposal treatment standard established through a 
    treatment variance, the treatment variance approval could include a 
    condition that restricted use of the treated hazardous waste in a 
    manner constituting disposal.
    ---------------------------------------------------------------------------
    
        \5\ As EPA explained in the May 12, 1997, Federal Register 
    notice, however, remediation activities involving replacement of 
    treated soils or other wastes onto the land is not a type of use 
    constituting disposal. The activity is a type of supervised 
    remediation, and is not the type of unsupervised recycling activity 
    covered by the use constituting disposal provisions. 62 FR at 26063, 
    May 12, 1997.
    ---------------------------------------------------------------------------
    
        EPA also notes that the Subpart CC rules, relating to control of 
    air emissions from tanks, containers, and surface impoundments managing 
    hazardous waste, state that if a waste has met the LDR treatment 
    standard set out in 40 CFR 268.40 (the generally-applicable treatment 
    standards, normally the Universal Treatment Standards), the waste is 
    not subject to further Subpart CC controls.6 See 40 CFR 
    264.1082 (c) (4) and 265.1082 (c) (4)) and 61 FR at 59941, November 25, 
    1996. The limitation to wastes that have achieved the generally-
    applicable treatment standard in fact means that the exemption is 
    unavailable to wastes receiving treatment variances that alter the 
    generally-applicable standards for organic hazardous constituents. EPA 
    is confirming here that this literal reading is intentional.
    ---------------------------------------------------------------------------
    
        \6\ It should be noted that the Subpart CC standards do not 
    apply to waste management units used solely for on-site treatment or 
    storage of hazardous waste that is generated as the result of 
    remedial activities required by RCRA corrective action authorities, 
    CERCLA authorities, or similar Federal or State authorities. See 40 
    CFR 264.1080 (b) (5) and 265.1080 (b) (5).
    ---------------------------------------------------------------------------
    
    III. Responses to Comment
    
        Most comments supported the Agency's proposal, or suggested that 
    there was no need to clarify the standard in the existing rule. The 
    main negative comment came from the Environmental Defense Fund, raising 
    a number of points.
        First, the commenter argued that the Agency's own closure rules for 
    impoundments create the environmentally adverse incentive to leave 
    wastes in place and thus create the dilemma to adopt alternative 
    treatment standards. The comment urges
    
    [[Page 64507]]
    
    amendment of the closure standards for impoundments.
        While it is correct that the closure rules for surface impoundments 
    (and landfills) create more opportunities to close with wastes left in 
    place than do closure standards for tanks, piles, containment 
    buildings, and drip pads, EPA did not, and is not, reopening any of the 
    closure standards in this proceeding.7 In developing the 
    standards for closure of surface impoundments, EPA allowed the option 
    of leaving wastes in place because of the practical difficulties of 
    removing large volumes of waste from impoundments, many of which had 
    been operating over long periods of time, and the recognition that, 
    when properly capped, some former surface impoundments can safely 
    contain wastes during and after post-closure care. 47 FR at 32320 and 
    32321, July 26, 1982. EPA also required, in the closure performance 
    standards, that releases must be minimized or controlled at units where 
    waste is left in place. 47 FR at 32320 and 32321, July 26, 1982. In 
    situations where such minimization or control is not achievable, the 
    closure performance standard would not be met and closure with waste in 
    place would not be available under the regulations. In these respects, 
    EPA's closure regulations for surface impoundments are identical to 
    those for landfills, where waste is purposefully disposed of in the 
    land-based units. EPA is re-evaluating the relationship between 
    requirements for closure of regulated units, including surface 
    impoundments, and requirements for RCRA corrective action and will take 
    this comment under consideration during the re-evaluation. In the 
    meantime, the Agency nevertheless intends to act now in order to assure 
    that the treatment variance option continues to provide a potential 
    intermediate alternative between full removal of waste followed by 
    treatment to the extent of best demonstrated technology on the one hand 
    and no waste removal at all on the other.
    ---------------------------------------------------------------------------
    
        \7\ The rules for most regulated units in essence require clean 
    closure, with wastes being allowed to be left in place only after a 
    showing that wastes remaining after initial removal and 
    decontamination cannot be practically removed or decontaminated. See 
    e.g., closure standards for piles in 40 CFR 265.258. The closure 
    rules for impoundments and landfills do not contain these 
    provisions, but rather provide alternative standards for closing 
    with wastes in place or for clean closure. See, e.g., 40 CFR 
    265.228.
    ---------------------------------------------------------------------------
    
        Second, the commenter argued that the circumstances under which 
    treatment variances could be approved based on the ``inappropriate'' 
    standard were not adequately defined. The commenter then went on to 
    note that most of the situations in which the Agency contemplated using 
    the ``inappropriate'' standard occurred in the remediation setting and 
    suggested that the Agency either wait until completion of the ongoing 
    rulemaking relating to management of contaminated environmental media, 
    or limit the scope of the variance to remediation 
    situations.8
    ---------------------------------------------------------------------------
    
        \8\ EPA proposed regulations addressing contaminated media at 61 
    FR 18780, April 29, 1996 and has not yet taken final action on this 
    proposal.
    ---------------------------------------------------------------------------
    
        EPA has addressed the comments regarding the specificity of the 
    ``inappropriate'' standard by adding clarifying language, based on 
    discussion in May 12, 1997 proposal, to the final regulations as 
    discussed above. Regarding the second part of this comment, EPA does 
    not believe it should await the outcome of the HWIR-Media proceeding to 
    finalize the clarifying amendment to the treatment variance rules. EPA 
    also notes that nothing in this rule forecloses any of the actions 
    proposed in the HWIR Media proposal, including further definition of 
    situations where treatment variances are appropriate--for example, 
    codification of the type of ``minimize threat'' variance determination 
    discussed in the HWIR-Media proposal. 61 FR at 18810-18812, April 29, 
    1996. The Agency is continuing to evaluate and review comments on this 
    part of the HWIR-Media proposal.
        The Agency is persuaded by the commenter's observation regarding 
    use of treatment variances in the context of remediation. Accordingly, 
    in response to this comment, EPA has chosen to expressly limit approval 
    of treatment variances using the ``environmentally inappropriate'' test 
    to remediation wastes. In this context, remediation waste includes all 
    solid and hazardous wastes and all media (including groundwater, 
    surface water, soils and sediments) and debris, which contain listed 
    hazardous waste or which themselves exhibit a hazardous waste 
    characteristic when such wastes are generated during remediation, such 
    as RCRA corrective action, CERCLA cleanup, and cleanup under a state 
    program. This definition is consistent with the existing definition of 
    remediation waste in 40 CFR 260.10 except that it is not limited to 
    wastes generated for purposes of corrective action under 40 CFR 264.101 
    or RCRA Section 3008(h). Since site-specific land disposal restriction 
    treatment variances will undergo review and approval by either EPA or 
    an authorized state, EPA does not believe it is necessary to limit the 
    eligible wastes to corrective action cleanups.
        Finally, the commenter went on to argue that the open-ended 
    proposal effectively reopened the question of whether site-specific 
    treatment variances (40 CFR 268.44 (h)) could be issued without going 
    through notice-and-comment rulemaking, the argument being that each 
    such variance would establish a new criterion for what ``not 
    appropriate'' means.
        Site-specific treatment variances can be granted without using 
    rulemaking procedures. 53 FR at 31199-31200, August 17, 1988. EPA did 
    not reopen this issue in this proceeding, which just is adopting 
    clarifying amendments which reflect EPA's longstanding practice and 
    interpretation of the treatment variance rules. 62 FR at 26059, May 12, 
    1997. However, to ensure there is no ambiguity over the application of 
    treatment variances, EPA is restoring language to 268.44(h) indicating 
    that the alternative LDR treatment standards established through the 
    treatment variance process are site-specific. This language has always 
    been part of 268.44(h) and was inadvertently omitted in the proposal of 
    this clarifying rule. In any case, the amendment adopted today contains 
    explicit qualifying language so that whatever basis, if any, existed 
    for the commenter's argument is no longer present.
        The same commenter, in oral conversations with Agency officials as 
    well as in public comments, maintained the importance of allowing 
    opportunity for public participation whenever a site-specific treatment 
    variance is being considered. These opportunities are already provided. 
    The Agency stated in 1988, when adopting 40 CFR 268. 44(h), ``[t]he 
    Agency agrees as a matter of policy to allow opportunity for public 
    notice and comment prior to granting a nonrulemaking variance from the 
    treatment standard. Because circumstances under which one might apply 
    for a site-specific variance vary, vehicles for public comment will be 
    specified on a case-by-case basis.'' 53 FR at 31200, August 17, 1988. 
    In response to this commenter's concerns, however, EPA has decided to 
    indicate in the rule that opportunity for public participation must be 
    provided when granting or denying any site-specific treatment variance. 
    In doing so, the Agency is simply repeating in the rule what it wrote 
    in the August 1988 preamble. The Agency does not view this step as 
    creating a new regulatory requirement or altering existing practice 
    and, by adding the August 1988 preamble language to the rule, is not 
    intending to
    
    [[Page 64508]]
    
    reopen the issue (settled in 1988) of whether site-specific treatment 
    variances can be approved or denied without going through rulemaking 
    procedures.
    
    IV. Withdrawal of Citgo Treatment Variance
    
        EPA granted a treatment variance to Citgo Petroleum on October 28, 
    1996 for wastes presently disposed in a large surface impoundment 
    awaiting closure. 61 FR 55718, October 28, 1996. Because the company 
    had the legal option of closing the impoundment with waste in place 
    (assuming the technical standards for such closure could be justified), 
    and was virtually certain to pursue that option if treatment of the 
    waste to the limit of best demonstrated technology was required, EPA 
    found that it was an environmentally superior result to assure clean 
    closure and partial treatment. Id. at 55721. The variance was in 
    essence used as an incentive to assure aggressive clean closure and the 
    associated waste treatment. EPA, as part of the May 12 notice, proposed 
    to reissue the variance under the clarified regulatory standard. 62 FR 
    at 26062-26061, May 12, 1997.
        Since the variance was granted, Citgo has chosen to pursue the 
    legal option of seeking to close the impoundment with waste left in 
    place. Because of Citgo's decision, EPA believes there is no longer any 
    basis for the Citgo treatment variance. If the company's application 
    for closure in place is granted, the variance is moot. If the 
    application is not granted, then the company will have to clean close 
    the impoundment and it will not be necessary to use the variance to 
    create a voluntary incentive for them to do so. Thus, in either case, 
    the basis for granting the variance no longer exists. Accordingly, EPA 
    is withdrawing the Citgo treatment variance in today's Notice. Citgo is 
    aware of the Agency's thinking, has discussed the issue with EPA, and 
    agrees not to oppose withdrawal of the variance.
    
    V. State Authorization
    
        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.
        Today's rule is being promulgated pursuant to section 3004(m) of 
    RCRA (42 U.S.C. 6924(m)), a provision added by HSWA. 9 
    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.
    ---------------------------------------------------------------------------
    
        \9\  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 all states, including the issuance of permits, 
    until the state is granted authorization to do so.
    ---------------------------------------------------------------------------
    
        EPA originally indicated that states could not be authorized to 
    review and approve national treatment variances pursuant to 40 CFR 
    268.44(a) because such variances could result in nationally-applicable 
    standards for a new waste treatability group. 52 FR at 25783, July 8, 
    1987. In the HWIR-Media proposal, EPA clarified that states could seek 
    authorization to review and approve site-specific treatment variances 
    pursuant to 40 CFR 268.44(h). 61 FR at 18828, April 29, 1996.
        The site-specific variance provision is less stringent than the 
    generally applicable LDR program (i.e., the underlying treatment 
    standard from which a variance is sought). Since today's final rule 
    clarifies the existing regulations, for authorization purposes it is 
    considered as stringent as, but no more stringent than the existing 
    site-specific variance regulations. Thus, states are not required to 
    adopt regulations equivalent to 268.44(h) either in its current form or 
    in the clarified form promulgated today. Although States are not 
    required to adopt regulations for site-specific LDR treatment 
    variances, EPA strongly encourages States to adopt and become 
    authorized for the clarified standards established today and is 
    committed to expediting the state authorization process for this rule. 
    In the meantime, EPA will continue to review and approve (as 
    appropriate) treatment variance applications in all States.
    
    VI. 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 considers today's final rule to be nonsignificant as 
    defined by the Executive Order and therefore not subject to the 
    requirement that a regulatory impact analysis has to be prepared. 
    Today's rule clarifies and codifies, in regulatory language, existing 
    EPA standards for the application of a treatability variance where the 
    treatment standard is not appropriate for the restricted waste subject 
    to the standard. Thus, because today's rule clarifies and codifies 
    existing EPA interpretation of the treatability variance provision, no 
    incremental costs are associated with this rulemaking.
    
    B. Regulatory Flexibility Analysis
    
        Pursuant to the Regulatory Flexibility Act (5 U.S.C. 601 et seq., 
    as amended by the Small Business Regulatory Enforcement Fairness Act of 
    1996 [SBREFA]) whenever an agency is required to publish a notice of 
    rulemaking for any proposed or final rule, it must prepare and make 
    available for public comment a regulatory flexibility analysis that 
    describes the effect of the rule on small entities (i.e., small 
    businesses, small organizations, and small governmental jurisdictions). 
    However, no regulatory flexibility analysis is required if the head of 
    an agency certifies the rule will not have a significant adverse 
    economic impact on a substantial number of small entities.
        SBREFA amended the Regulatory Flexibility Act to require Federal 
    agencies to provide a statement of the factual basis for certifying 
    that a rule will not have a significant economic impact on a 
    substantial number of small entities. The following discussion explains 
    EPA's determination.
        EPA has codified regulatory language in today's rule that 
    petitioners of restricted wastes that wish to obtain a treatment 
    variance do not have to show technical infeasibility when the treatment 
    technology is not appropriate to the waste. This regulatory language 
    clarifies long standing and current Agency interpretation of the 268.44 
    that the two tests of technical infeasibility and inappropriateness are 
    independent.
    
    [[Page 64509]]
    
    (See above discussion and 61 FR 55718 at 55720-21, October 28, 1996; 53 
    FR at 31200, August 17, 1988; 55 FR 8666 and 8760, March 8, 1990; 61 FR 
    18780 and 18811, April 29, 1996.) Because this regulatory language 
    codifies existing EPA interpretation of current regulations, it imposes 
    no costs or economic impacts on small entities applying for 
    treatability variances.
        Because this clarification does not impose an adverse economic 
    impact to any small entity that is either generator of restricted waste 
    or an owner/operator of a treatment, storage or disposal facility 
    managing such waste that is petitioning the Agency for a variance from 
    the treatment standard, I hereby certify that this rule will not have a 
    significant adverse economic impact on a substantial number of small 
    entities. This rule, therefore, does not require a regulatory 
    flexibility analysis.
    
    C. 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 the 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.
        Because this regulatory language codifies current EPA 
    interpretation of existing treatability variance language and thus 
    imposes no costs, EPA 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 is not expected to incur costs 
    exceeding $100 million. EPA has fulfilled the requirement for analysis 
    under the Unfunded Mandates Reform Act.
    
    D. Submission to Congress and the General Accounting Office
    
        Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
    Regulatory Enforcement Fairness Act of 1996, EPA submitted a report 
    containing this rule and other required information to the U.S. Senate, 
    the U.S. House of Representatives and the Comptroller General of the 
    General Accounting Office prior to publication of the rule in today's 
    Federal Register. This rule is not a ``major rule'' as defined by 5 
    U.S.C. 804(2).
    
    List of Subjects in 40 CFR Part 268
    
        Environmental protection, Hazardous waste, Reporting and 
    recordkeeping requirements.
    
        Dated: December 1, 1997.
    Carol M. Browner,
    Administrator.
    
        For the reasons set out in the preamble, title 40, chapter 1 of the 
    Code of Federal Regulations is amended as follows:
    
    PART 268--LAND DISPOSAL RESTRICTIONS
    
        1. The authority citation for part 268 continues to read as 
    follows:
    
        Authority: 42 U.S.C. 6905, 6912(a), 6921, and 6924.
    
        2. Section 268.44 is amended to revise paragraphs (a) and (h), add 
    paragraph (m), and remove paragraph (p) as follows:
    
    
    Sec. 268.44  Variance from a treatment standard.
    
        (a) Based on a petition filed by a generator or treater of 
    hazardous waste, the Administrator may approve a variance from an 
    applicable treatment standard if:
        (1) It is not physically possible to treat the waste to the level 
    specified in the treatment standard, or by the method specified as the 
    treatment standard. To show that this is the case, the petitioner must 
    demonstrate that because the physical or chemical properties of the 
    waste differ significantly from waste analyzed in developing the 
    treatment standard, the waste cannot be treated to the specified level 
    or by the specified method; or
        (2) It is inappropriate to require the waste to be treated to the 
    level specified in the treatment standard or by the method specified as 
    the treatment standard, even though such treatment is technically 
    possible. To show that this is the case, the petitioner must either 
    demonstrate that:
        (i) Treatment to the specified level or by the specified method is 
    technically inappropriate (for example, resulting in combustion of 
    large amounts of mildly contaminated environmental media); or
        (ii) For remediation waste only, treatment to the specified level 
    or by the specified method is environmentally inappropriate because it 
    would likely discourage aggressive remediation.
    * * * * *
        (h) Based on a petition filed by a generator or treater of 
    hazardous waste, the Administrator or his or her delegated 
    representative may approve a site-specific variance from an applicable 
    treatment standard if:
        (1) It is not physically possible to treat the waste to the level 
    specified in the treatment standard, or by the method specified as the 
    treatment standard. To show that this is the case, the petitioner must 
    demonstrate that because the physical or chemical properties of the 
    waste differ significantly from waste analyzed in developing the 
    treatment standard, the waste cannot be treated to the specified level 
    or by the specified method; or
        (2) It is inappropriate to require the waste to be treated to the 
    level specified in the treatment standard or by the method specified as 
    the treatment standard, even though such treatment is technically 
    possible. To show that this is the case, the petitioner must either 
    demonstrate that:
        (i) Treatment to the specified level or by the specified method is 
    technically inappropriate (for example, resulting in combustion of 
    large amounts of mildly contaminated environmental media where the 
    treatment standard is not based on combustion of such media); or
        (ii) For remediation waste only, treatment to the specified level 
    or by the specified method is environmentally inappropriate because it 
    would likely discourage aggressive remediation.
        (3) Public notice and a reasonable opportunity for public comment 
    must be provided before granting or denying a petition.
    * * * * *
        (m) For all variances, the petitioner must also demonstrate that 
    compliance with any given treatment variance is sufficient to minimize 
    threats to human health and the environment posed by land disposal of 
    the waste. In evaluating this demonstration, EPA may take into account 
    whether a treatment variance should be approved if the subject waste is 
    to be used in a manner constituting disposal pursuant to 40 CFR 266.20 
    through 266.23.
