    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Agency is finalizing treatment standards for hazardous 
    wastes generated from wood preserving operations, and is making a 
    conforming amendment to the standard for wastes from production of 
    chlorinated aliphatics which carry the F024 hazardous waste code. These 
    treatment standards will minimize threats to human health and the 
    environment posed by these wastes. In addition, this final rule revises 
    the land disposal restrictions (LDR) program to significantly reduce 
    paperwork requirements by 1.6 million hours. This rule also finalizes 
    both the decision to employ polymerization as an alternative method of 
    treatment for certain ignitable wastes as well as the decision not to 
    ban certain wastes from biological treatment because there is no need 
    to classify these wastes as ``nonamenable.'' It also clarifies an 
    exception from LDR requirements for de minimis amounts of 
    characteristic wastewaters. Finally, this rule excludes processed 
    circuit boards and scrap metal from RCRA regulation which is intended 
    to promote the goal of safe recycling.
    
    EFFECTIVE DATE: This final rule is effective on August 11, 1997 except 
    Secs. 148.18(b) and 268.30(b), which are effective on May 12, 1999.

    I. Background
    
        In the 1984 Hazardous and Solid Waste Amendments (HSWA) of the 
    Resource Conservation and Recovery Act (RCRA), Congress specified that 
    land disposal of hazardous waste is prohibited unless the waste meets 
    treatment standards established by EPA. HSWA requires that treatment 
    standards must substantially diminish the toxicity or mobility of 
    hazardous waste, so that short and long term threats to human health 
    and the environment are minimized. The treatment standards are part of 
    the Land Disposal Restrictions Program.
        Today's final rule is one part of the collection of land disposal 
    restrictions (LDR) rules known as ``Phase IV.'' They are the latest in 
    a series of LDR rules that establish treatment standards for newly 
    listed and identified wastes, and that resolve other hazardous waste 
    matters.
        EPA proposed the Phase IV rule in two proposed rules (60 FR 43654, 
    August 22, 1995; and 61 FR 2338, January 25, 1996), and subsequently 
    issued a Notice of Data Availability on Phase IV issues (61 FR 21418, 
    May 10, 1996). The attached rule finalizes portions of those earlier 
    proposals. Other proposed revisions are in a second supplemental 
    proposed rule elsewhere in this Federal Register.
        EPA estimates that the directly measurable benefits associated with 
    the land disposal restrictions treatment standards in this rule are 
    limited relative to the costs that may be incurred. Therefore, the 
    relative priority of addressing these risks could be questioned. 
    However, we do not believe, for this specific action, that a simple 
    cost effectiveness measure alone provides a sufficient basis for 
    decision-making. As discussed below, the preference for permanent 
    treatment of hazardous wastes is part of the basic policy structure 
    which Congress enacted when it amended RCRA in 1984, and reflects 
    concern over the technological uncertainties regarding risks and long 
    term protectiveness of land disposal and the intent to assure that 
    waste management practices are protective for future generations.
        The whole premise of the LDR legislation is that risks posed by 
    land disposal of hazardous wastes are inherently uncertain to evaluate 
    and that land-based units are incapable of long term containment. Land 
    disposal units (such as landfills, surface impoundments, and waste 
    piles) are engineered units that can and have failed in the past with 
    significant consequences to human health and the environment. For this 
    reason, Congress required that hazardous wastes be pretreated before 
    disposal by ``treatment [which] should be the best that has been 
    demonstrated to be achievable.'' Congressional Record of July 25, 1984 
    (S9178). The technology-based approach of the land disposal 
    restrictions provides a measure of insurance against the potential for 
    failure in these land based units.
        Given these facts, and evident Congressional intent, EPA continues 
    to believe that the LDR prohibitions and treatment standards are 
    justified in many instances. EPA sets treatment standards that reduce 
    toxicity and mobility of hazardous constituents (or require recycling), 
    and EPA also requires that the treated wastes be placed in reasonably 
    secure land disposal units. However, EPA does believe that, in some 
    situations, the current LDR rules may not provide the optimum 
    regulatory approach. In those situations, EPA will look to other 
    mechanisms to address those relatively low risk scenarios.
    
    II. Potentially Regulated Entities
    
        Entities potentially regulated by this final rule vary according to 
    the section of the rule. The following table breaks down the categories 
    industries that may be regulated according to each major section. The 
    table is not intended to be exhaustive, but rather to provide a guide 
    for readers regarding entities likely to be regulated by this action. 
    This table lists the types of entities that EPA is now aware could 
    potentially be regulated by this action. Other types of entities not 
    listed in the table could also be regulated.

    Wood Preserving (Waste Codes F032, F034, and F035) and Revised 
    Treatment Standard for Chlorinated Aliphatics Waste (F024)
    
    A. Summary
    
        EPA is promulgating UTS limits as the treatment standards for the 
    hazardous constituents in wood preserving wastes F032, F034, and F035, 
    as proposed. (See 60 FR 43654, August 24, 1995; 60 FR 546451, October 
    25, 1995; and 61 FR 21417, May 10, 1996.) In addition, EPA is 
    establishing a compliance alternative for dioxin and furan (D/F) 
    constituents in nonwastewater and wastewater forms of F032, namely 
    allowing use of a method of treatment--combustion--for these 
    constituents. Thus, if this method of treatment is utilized, combustion 
    residues would not have to be analyzed for D/F constituents. The 
    alternative is only available for F032 residues from units subject to 
    the standards in Part 264 subpart O or Part 266 subpart H, or from 
    interim status incinerators which have made a specific demonstration 
    that they operate in a manner equivalent to a Part 264 or Part 266 
    combustion unit. EPA also is amending the treatment standard previously 
    established for F024 wastes. EPA is adopting the alternative compliance 
    standard for F032 as the standard for F024. The practical effect of 
    this change will be to limit somewhat the type of facilities that can 
    combust F024.
    
    B. Determination of BDAT
    
    1. General
        EPA has determined that combustion (CMBST) represents BDAT for 
    organics in nonwastewater forms of F032 and F034 (i.e., the treatment 
    standards are based on the performance of combustion technology). For 
    organics in wastewater forms of F032 and F034, EPA has determined that 
    a single treatment technology or a normal wastewater treatment train 
    can meet the treatment standards promulgated today. As explained in the 
    Final Best Demonstrated Available Technology Background Document for 
    Wood Preserving Wastes--F032, F034, and F035 (Wood Preserving 
    Background Document for this rule), EPA has determined that wastewater 
    treatment technologies such as biological treatment, steam stripping, 
    carbon adsorption, or combinations of these technologies can treat 
    organics regulated in F032 and F034 to the concentration levels 
    promulgated today. These wastewater treatment technologies are 
    available to, or in use at, existing wood preserving facilities.
        For metals in nonwastewater forms of F032, F034, and F035, EPA has 
    determined that the promulgated treatment standards can be based on 
    (slag) vitrification for arsenic and on stabilization for chromium 
    (total). The treatment standard for arsenic also can be achieved using 
    stabilization treatment (see the Wood Preserving Background Document). 
    For wastewater forms of F032, F034, and F035, EPA has determined that 
    treatment levels can be achieved by lime addition followed by 
    sedimentation and filtration for arsenic, and by chemical precipitation 
    followed by sedimentation for chromium. (Of course, since no method of 
    treatment is required to be used under the promulgated treatment 
    standards, any type of treatment other than impermissible dilution may 
    be used to achieve these concentration levels.)
    2. F032 Wastewaters
        Some commenters felt that the limits proposed for D/F in F032 
    wastewaters, namely the existing UTS limits, were not achievable. 
    Commenters felt that EPA's own wastewater characterization data showed 
    that the D/F concentrations in untreated F032 wastewaters were orders 
    of magnitude higher than the untreated concentrations in the wastewater 
    samples used in establishing the UTS limits. They also emphasized that 
    biological treatment normally removes D/F constituents in the order of 
    78% of influent pollutants and thus, may yield an effluent with higher 
    concentrations than those proposed by EPA.
        EPA has examined the available data on the characterization of 
    F032, prevailing management practices for wastewaters as difficult to 
    treat as F032, and for wastewaters managed by biological treatment 
    systems. EPA acknowledges that the concentrations of D/F in F032 
    wastewaters, as generated, are much higher than those treated by the 
    biological treatment system supporting the existing UTS limits for D/F. 
    However, based on the available data on wastewater treatment practices 
    at wood preserving facilities, EPA believes that prevailing wastewater 
    treatment practices can be optimized or upgraded to meet the D/F limits 
    promulgated for F032 wastewaters. As explained in the BDAT Background 
    Document, pretreatment steps can be, and are, used to reduce influent 
    concentrations to biotreatment units to levels comparable to those on 
    which the treatment standards are based, and EPA believes the same 
    level of performance is achievable for wood preservers. (See the wood 
    preserving background document and the BDAT response to comments 
    document for additional discussion on EPA's rationale and data review.)
        Another commenter asked EPA to withdraw its proposal for the 
    regulation of D/F constituents in F032 wastewaters. The commenter 
    believes that the regulation of PCP and polynuclear aromatic 
    hydrocarbons (PAH) can ensure the reduction of D/F in F032 wastewaters. 
    The commenter also submitted data with regard to concentrations of D/F, 
    PCP, and PAH analytes in two effluent F032 wastewaters treated by 
    activated carbon adsorption. These data appear to support the 
    commenter's statement that monitoring of PCP and PAHs may serve as a 
    surrogate candidate for the reduction of D/F levels in these particular 
    effluent wastewaters. However, EPA lacks data to determine if the 
    alternative surrogate constituents
    
    [[Page 26001]]
    
    proposed for regulation can also serve as surrogates for monitoring the 
    treatment of D/F in wastewater treatment effluents resulting from other 
    treatment technology trains that may achieve the proposed UTS, and has 
    therefore chosen not to adopt this suggestion.
    3. F034 Wastes
        Some commenters objected to EPA's proposed regulation of arsenic 
    and chromium in F034 wastes, but their arguments were not persuasive. 
    One argument was that F034 wastes typically do not contain arsenic and 
    chromium and that they should only be regulated if chromated copper 
    arsenate (CCA) is used at the facility generating F034 at 
    concentrations exceeding treatment standards. EPA's data supporting the 
    listing of F034 wastes in fact show that arsenic and chromium are 
    frequently present in F034. (See Background Document Supporting the 
    Final Listing for Wastes from Wood Preserving Processes, November, 
    1990.) Further, EPA determined that these two metal constituents are 
    toxic and that their concentrations in untreated F034 wastes also 
    supported the listing of these wastes as RCRA hazardous waste F034. 
    (See Background Document Supporting the Final Listing for Wood 
    Preserving Wastes from Wood Preserving, November, 1990; 55 FR 50458-59, 
    December 6, 1990; and 53 FR 53299-300, Table 13, December 30, 1988.) 
    Because treatment of organic constituents in F034 may not reduce the 
    mobility of these metals, EPA is promulgating treatment standards that 
    will assure that the mobility of these metal constituents is reduced 
    prior to disposal, consistent with a core LDR requirement to develop 
    treatment standards which ``substantially reduce the likelihood of 
    migration of hazardous constituents from the waste * * *''. RCRA 
    section 3004(m)(1). Furthermore, EPA points out that treaters of this 
    waste can address the monitoring of these metal constituents in their 
    permit Waste Analysis Plans (WAP). See 55 FR at 22669, June 1, 1990; 
    Chemical Waste Management v. EPA, 976 F.2d 2, 31 (D.C. Cir. 1992); 
    cert. denied 113 S.Ct. 1961 (1993).
    4. F035 Wastes
        Other commenters were concerned with the achievability of arsenic 
    limits in wastewater and nonwastewater forms of F035. One commenter was 
    concerned that EPA was mandating the use of vitrification as opposed to 
    setting a numerical limit. Other commenters felt that vitrification is 
    an inappropriate technology for setting arsenic treatment limits and 
    that EPA should set, instead, UTS limits that are based on the 
    performance of stabilization technologies.
        None of these commenters have submitted treatment performance data 
    supporting their inability to meet the proposed UTS limits, nor have 
    they documented that their waste will behave differently when treated 
    by stabilization or vitrification practices. The treatment technology 
    supporting numerical limits for arsenic in nonwastewater forms of F032 
    is vitrification. However, EPA believes that arsenic limits can also be 
    achieved via stabilization based on treatment data supporting the 
    promulgation of the UTS limit for arsenic (see Final Best Demonstrated 
    Available Technology (BDAT) Background Document for Universal Standards 
    Volume A: Universal Standards for Nonwastewater Forms of Listed 
    Hazardous Wastes). In addition, today's promulgated treatment levels do 
    not preclude the use of other treatment alternatives such as 
    stabilization, as long as such alternatives do not constitute land 
    disposal or impermissible dilution. As a result, EPA is promulgating 
    treatment limits for arsenic as proposed.
    
    C. Alternative Combustion Treatment Standard for Dioxins and Furans in 
    F032
    
    1. Today's Action
        This notice establishes combustion (defined at 40 CFR 268.42, Table 
    1, CMBST) as an alternative compliance treatment standard option for D/
    F in F032. Combustion is the basis for the D/F numerical limits, and 
    properly conducted combustion should effectively destroy D/F 
    constituents, If this method of treatment is used to treat F032 in 
    certain specified combustion devices, there is no need to monitor 
    compliance with the D/F numerical limits established for D/F 
    constituents. However, all other organic and metal constituents will 
    require monitoring prior to disposal. This approach is patterned after 
    EPA's promulgation of a similar alternative treatment standard for D/F 
    in F024 (wastes from production of chlorinated aliphatics). See 55 FR 
    22580-81, June 1, 1990. EPA discussed this approach in detail in a 
    Notice of Data Availability (NODA) that appeared in the Federal 
    Register on May 10, 1996 (61 FR 21418).
        In general, EPA is providing a method of treatment as an 
    alternative to actual D/F measurement that will be equally protective, 
    and will assure availability of effective treatment for these wastes. 
    The alternative, namely not providing the alternative treatment 
    standard, leaves open the real possibility of these wastes being 
    refused treatment, an environmentally worse result. EPA also notes that 
    its experience with F024 waste treatment, for which there is a parallel 
    treatment regime, has been satisfactory: these wastes are effectively 
    treated by combustion technology, and sufficient treatment capacity has 
    remained available once EPA promulgated the alternative treatment 
    standard which did not require analysis of D/F in treatment residues.
    2. Background
        EPA proposed numerical treatment standards for F032 constituents on 
    August 22, 1995. Several members of the regulated community expressed 
    concern that EPA's proposal to regulate D/F constituents in F032 may 
    result in problems finding treatment facilities willing to accept the 
    waste. D/F are very controversial hazardous waste constituents that 
    often trigger public opposition if documented at any concentrations 
    regardless of the estimated risks presented. D/F monitoring also adds 
    significantly to monitoring costs. See generally, 55 FR at 22580-81. 
    Commenters emphasized that owners and operators of combustion devices 
    had informed them that their combustion facilities will not accept F032 
    if EPA requires the monitoring of D/F in combustion residues. Further, 
    commenters noted that if combustion is conducted properly, analysis of 
    D/F is unnecessary.
        The American Wood Preservers Institute (AWPI) and the Penta Task 
    Force asked EPA to consider establishing an alternative treatment 
    standard that sets a method of treatment as an alternative to the 
    numerical limits for D/F in F032.
        The Penta Task Force submitted data to show that the concentrations 
    of D/F in F032 are substantially lower than those EPA reported in the 
    F032 Listing Background Document. They stated their belief, along with 
    AWPI, that D/F in F032 should be regulated like D/F in F024.
    3. Summary of Phase IV NODA for F032
        EPA examined these new data and concerns and proposed in the NODA 
    to codify combustion (CMBST) as an alternative method of treatment for 
    D/F in F032. EPA also requested comments on potential regulatory 
    controls on combustion devices to assure that D/F destruction is 
    conducted only in well-designed and well-operated combustion devices. 
    EPA proposed three regulatory suboptions for implementing a CMBST 
    standard. One suboption was to merely apply the existing F024 
    alternative
    
    [[Page 26002]]
    
    combustion treatment standard to F032 with applicable regulatory 
    controls in Part 264, 265, or 266. The second suboption was to revise 
    the alternative D/F standard for F024, and establish for F024 and F032, 
    a CMBST standard alternative, that would limit the combustion of F032 
    and F024 to RCRA permitted or interim status combustion devices which 
    have demonstrated the ability to achieve a dioxin toxicity equivalent 
    (TEQ) air emission discharge limit of 0.2 ng/dscm. The third suboption 
    was to revise the F024 standard, and to establish an alternative 
    standard for F024 and F032 that limits the combustion of F024 and F032 
    to RCRA permitted combustion devices. (In all of these options, and in 
    today's final rule, the restriction on types of devices applies only to 
    facilities opting to comply with the D/F standard without analyzing 
    treatment residues.)
    4. Review of Major Comments on Phase IV NODA and Promulgation of A 
    Modified Version of Suboption Three
        The majority of commenters supported the proposed compliance 
    alternative setting CMBST as a method of treatment for D/F. In 
    addition, the majority of commenters preferred suboption 1 (i.e., allow 
    combustion in a RCRA interim status or permitted device) to ensure that 
    combustion is conducted in well-designed and well-operated devices. A 
    significant number of commenters also were concerned that adoption of 
    suboption 3 may have excluded the use of well-designed and well-
    operated interim status combustion devices operated under the Part 266 
    rules applicable to boilers and industrial furnaces.
        The majority of commenters argued that it would be premature for 
    the Agency to adopt suboption 2 whereby a D/F emission limit of 0.2 ng/
    dscm TEQ would be established given that the Agency has only recently 
    proposed such an emission standard for hazardous waste burning 
    incinerators, cement, and lightweight aggregate kilns under the maximum 
    achievable control technology (MACT) rule. See 61 FR 17358 (April 19, 
    1996).1 The Agency believes that this concern is warranted 
    given that EPA has received substantial comments on whether that 
    standard is appropriate for those devices and has not made a final 
    decision as to an appropriate standard.
    ---------------------------------------------------------------------------

    cmbust.htm''.
    ---------------------------------------------------------------------------
    
        The Agency believes that suboption 3 (i.e., allow combustion of 
    FO24 and FO32 only in RCRA-permitted devices), as proposed, was too 
    restrictive. EPA agrees with the commenters that interim status boilers 
    and industrial furnaces operated under Part 266 should qualify for the 
    proposed alternative CMBST compliance standard as well. These devices 
    are subject to interim status combustion controls which limit carbon 
    monoxide (CO) or total hydrocarbon levels (THC) in combustion gases, 
    thus ensuring that the devices operate under good combustion 
    conditions. The standards also can include explicit control of D/F 
    under specified conditions (see section 266.103 (c)(1)). Although these 
    controls do not provide the explicit demonstration of destruction of 
    toxic organics in the waste feed that the DRE (Destruction and Removal 
    Efficiency) for permitted combustion devices standard provides, the 
    Agency believes that they establish good combustion, and may, in some 
    cases, provide even better assurance of operations under good 
    combustion conditions than the bare DRE standard.
        Accordingly, the Agency believes that it is not necessary to 
    restrict burning to RCRA-permitted devices because boilers and 
    industrial furnaces operating under interim status are required to 
    operate under good combustion conditions which should ensure 
    destruction of toxic organic compounds in the waste feed.
        The Agency acknowledges that ensuring that the combustion device 
    operates under good combustion conditions (i.e., either under a DRE 
    standard or by limiting carbon monoxide (CO) and total hydrocarbon 
    levels (THC) in stack gas) may not necessarily ensure control of D/F 
    emissions. This is because D/F can be formed in the post-combustion 
    zone of the device--in the duct work and particulate matter control 
    devices that operate at temperatures above 350 deg.F. Boilers and 
    industrial furnaces operating under these conditions must comply with 
    specific D/F emission standards. (See 40 CFR 266.103(c)(1) and 
    266.104(e).) In addition, under existing Omnibus permit authority, 
    permit writers have the authority, if the permitting authority 
    demonstrates that it is necessary to protect human health and the 
    environment (RCRA section 3005(c)(3)), to impose operating requirements 
    more stringent than those authorized by regulations. This authority 
    could be invoked (assuming the requisite showing is made) to justify 
    controls on permitted hazardous waste incinerators.
        EPA currently lacks similar Omnibus permit authorities for 
    incinerators regulated under Part 265, Subpart O. In addition, unlike 
    the standards for interim status boilers and industrial furnaces, the 
    interim status standards for hazardous waste incinerators do not 
    contain controls on good combustion (i.e., CO or THC controls), a DRE 
    requirement, or explicit standards for D/F. EPA is concerned, 
    therefore, that the combustion of F032 and F024 in Part 265 
    incinerators may not consistently achieve the treatment objectives 
    sought by the alternative combustion compliance treatment standard. As 
    a result, EPA cannot support the promulgation of suboption 1 for 
    incinerators operated under Part 265. (See also 265.352(a), forbidding 
    combustion of the acutely hazardous D/F-containing wastes in interim 
    status hazardous waste incinerators.)
        Although EPA's finding here is that the interim status incinerator 
    standards may be inadequate for qualifying for a CMBST treatment 
    standard for D/F, EPA believes that on an ad-hoc basis, a site-specific 
    determination can be made pursuant to 40 CFR Part 268.42(b) to extend 
    the availability of a ``CMBST'' treatment standard to an individual 
    interim status incinerator. The availability of a CMBST treatment 
    standard to a facility combusting F032 or F024 in a Part 265 
    incinerator will require the accomplishment of a two-step process. One 
    step is for the facility to demonstrate to a regional or state official 
    that the combustion of D/F in F032 (or F024, if applicable) at the 
    facility uses controls to assure good combustion and control of D/F. 
    These would typically be the CO/THC standards and D/F standards found 
    in Part 266. The second step is that the facility solicits from EPA's 
    Headquarters an equivalent treatment determination under Part 
    268.42(b). (EPA believes both steps are necessary because normally some 
    type of direct interaction with the Region or State with the facility 
    is needed to evaluate performance of the combustion process, and the 
    treatment equivalency administrative process remains an EPA 
    Headquarters task.)
    5. Revised Treatment Standard for F024 Wastes
        The current F024 treatment standard requires CMBST as a method of 
    treatment, which, under the definition at 268.42, Table 1, allows 
    combustion in Part 265 Subpart O interim status incinerator (along with 
    other types of combustion devices). Today's rule makes the treatment 
    standard for F024 identical to today's alternative combustion standard 
    for F032. The existing standard allows combustion in permitted units or 
    interim status incinerators (Part 265 subpart O). The new standard 
    would require that an interim status incinerator receive a
    
    [[Page 26003]]
    
    determination of equivalent treatment under 268.42(b), as described for 
    the F032 standard above. As described above, this restricts the burning 
    to facilities with combustion controls that ensure proper destruction 
    of D/F.
    
    D. Soil and Debris Contaminated With Wood Preserving Wastes
    
    1. Summary of Comments
        Several commenters asked EPA to revise its policy that media 
    contaminated with hazardous listed wastes is subject to the treatment 
    standard for the contaminated waste, and to set instead risk-based 
    treatment levels. They asked EPA to delay the applicability of the 
    Phase IV final rule until the Hazardous Waste Identification Rule for 
    contaminated hazardous media is promulgated in order to lessen 
    potential disruptions to ongoing remediation activities. In addition, 
    other commenters argued that the proposed treatment standards for 
    organics and D/F were unachievable by remediation technologies.
    2. LDR Requirements Do Apply to Contaminated Media
        Commenters stated that hazardous media should be exempt from LDR 
    requirements until EPA finalizes HWIR for contaminated media. This 
    issue was settled in the Phase II final rule (50 FR at 47986-7, 
    September 19, 1994) if not before, and it is not being reopened in this 
    final rule.
    3. Technology-versus Risk-based Treatment Limits
        The principal objection to the proposed treatment standards was 
    that the values do not reflect risk, that is, the standards are based 
    on performance of a treatment technology rather than on assessment of 
    risks to the human health and the environment posed by the waste. The 
    question of technology-versus risk-based treatment standards has been 
    raised throughout the development of the land disposal restrictions 
    program. The Agency is not reopening this issue in this final rule. 
    See, instead discussion in the Phase II final rule (59 FR at 47986, 
    September 19, 1994). EPA does specifically find, however, that the 
    treatment standards for these contaminated media are not established 
    below levels at which threats to human health and the environment are 
    minimized. In part, this finding turns on the Agency's present 
    inability to quantify this level. In addition, for these wastes, the 
    presence of extremely toxic hazardous constituents (arsenic, D/F, PCP), 
    plus the widespread contamination already caused by past land disposal 
    of these wastes (see, e.g. the background documents to the Listing 
    rules for F032, F034, and F035) warrant treatment which effectively 
    destroys, removes, or immobilizes hazardous constituents to the 
    promulgated levels.
    4. UTS Limits and the Performance of Remedial Treatment Technologies
        The third issue raised by the commenters is whether or not the UTS 
    limits promulgated for organics can be achieved by all remediation 
    technologies currently being used at wood preserving facilities. The 
    UTS limits promulgated for organics and D/F regulated in nonwastewater 
    forms of wood preserving wastes are based on the performance of (and 
    are routinely achievable by) combustion technologies. EPA does not have 
    to set treatment standards that are achievable by all, or even several, 
    treatment technologies. The treatment limits promulgated for D/F 
    constituents in nonwastewater forms of F032 are based on the combustion 
    of solids, liquids, and soils contaminated with D/F constituents, 
    namely acutely hazardous wastes F020, F022, F023, F026, and F027 (see 
    51 FR 1733, January 14, 1986). EPA's existing technical guidance 
    documents describing technological options for treating contaminants 
    found at wood preserving facilities often recommend incineration as a 
    viable technology for cleaning up ``hot spots'' of organics and D/F 
    contaminants. These guidance documents also emphasize that incineration 
    is usually able to treat below cleanup levels and LDR treatment limits. 
    (See Presumptive Remedies for Soils, Sediments, and Sludges at Wood 
    Treater Sites, Directive 9200.5-162, NTIS #PB-95-963410; Technology 
    Selection Guide for Wood Treater Sites, EPA 540-F-93-020 or Pub.9360.0-
    46FS; and Contaminants and Remedial Options at Wood Preserving Sites, 
    EPA/600/R-92/182.)
        Available data on the performance of noncombustion technologies 
    such as thermal desorption and chemical dehalogenation also do not 
    necessarily support the commenters' claim that other remedial 
    technologies will fail to meet the treatment limits promulgated today. 
    Based on the available information, EPA believes that chemical 
    dehalogenation (for D/F and chlorinated organic constituents) and 
    thermal desorption (for organics and D/F constituents) generally can be 
    optimized to meet the UTS limits promulgated today. (See Wood 
    Preserving Background Document and Technical Guidance documents cited 
    above.) Furthermore, it may be necessary to use two or more treatment 
    technologies to achieve the limits, as EPA's Technical Guidance 
    documents point out. This is, however, a site-specific determination, 
    and the ability of a treatment train to meet or fail UTS or cleanup 
    limits can only be assessed through the findings of a feasibility 
    study.
    
    IV. Improvements to the Land Disposal Restrictions Program
    
    A. Significant Reduction in LDR Paperwork
    
        Summary: The LDR regulations heretofore required hazardous waste 
    handlers to include LDR notifications with each shipment of waste sent 
    to treaters or disposers. Today EPA is amending the rule to require 
    only a one-time notification, rather than with each shipment of 
    hazardous waste. The one-time notification would apply to shipments of 
    all restricted hazardous wastes, and so would include lab packs. No new 
    notification would be required unless there were a change in the waste, 
    process, or receiving facility. This amendment will save approximately 
    1,630,000 hours spent by the private sector on paperwork. EPA is also 
    promulgating other paperwork reduction actions, as proposed.
    1. Background
        In January 1995, EPA announced a goal to reduce the reporting and 
    record keeping burden imposed by its regulations by 25 percent by June 
    30, 1996. This announcement initiated implementation of one of the 
    reinvention projects set forth in the President's March 16, 1995, 
    report, ``Reinventing Environmental Regulations.'' The baseline from 
    which the 25 percent reduction was to be calculated was the reporting 
    and record keeping burden hours as described in the Information 
    Collection Request (ICR) documentation as of January 1, 1995.
    2. Discussion of Specific Paperwork Changes
        The LDR program imposes a significant reporting and record keeping 
    burden that is being decreased significantly by changes being made in 
    today's rule. It is estimated that the changes being made today result 
    in a reduction of over 1.6 million hours per year of paperwork burden. 
    Furthermore, these changes are not likely to compromise the 
    protectiveness or enforceability of the LDR regulations.
        Most commenters on this issue supported the proposed paperwork 
    changes. Almost all commenters addressing this issue agreed that the 
    proposed changes made sense, and that
    
    [[Page 26004]]
    
    it would be beneficial to the regulated community to reduce the 
    paperwork burden. A few commenters expressed concern that the 
    reductions in LDR paperwork could be an incentive for mismanagement of 
    hazardous wastes. The Agency acknowledges that although the potential 
    for mismanagement is real, inspection and enforcement efforts have 
    been, and will continue to be, a disincentive to facilities to provide 
    false or misleading information about the hazardous wastes at their 
    sites. This disincentive is believed to be far more important than the 
    frequency with which the regulated community must create notification 
    and certifications. The Agency, therefore, is promulgating the 
    paperwork reductions despite this concern.
        Much of the language specifying what must be included on LDR 
    notifications has been rewritten to include reductions in paperwork 
    burden and to make it easier for the regulated community to understand 
    the requirements to which it must adhere. Rewriting this section has 
    resulted in the renumbering of the regulatory paragraphs. The new 
    numbering for this section is used in this discussion. Also, the 
    generator paperwork requirements are consolidated into a table at 
    Sec. 268.7(a)(4).
        Under the requirements of Sec. 268.7(a), generators managing 
    restricted hazardous wastes must determine whether their wastes meet 
    the applicable treatment standards at the point of generation, or are 
    otherwise exempt from those standards. Generators then must notify, in 
    writing, either the treatment or disposal facility about their waste. 
    The Agency is changing the notification requirement under 
    Sec. 268.7(a)(2) from one requiring a notice accompany each waste 
    shipment to one allowing an one-time notification that would accompany 
    the first waste shipment and would also be placed in the generator's 
    files. If a generator repeatedly generates wastes which do not meet the 
    applicable treatment standards, but the composition of these wastes, or 
    the process generating the wastes, or the treatment facility receiving 
    the wastes does not change, then the generator is only required to 
    submit a one-time notification to the receiving treatment facility and 
    to place a copy in their files. If the waste, process, or the receiving 
    treatment facility changes, the generator is required to send a new 
    notice to the receiving facility, and place a copy of this new notice 
    in their files. One commenter stated that the concept of what 
    constituted a change in one's waste was vague and should be clarified 
    so that a new notification would be required only when a change in the 
    waste affects the determination of which treatment standards apply. The 
    Agency agrees that only when a change in the waste affects the 
    determination of which treatment standards apply must the generator 
    create a new LDR notification.
        The Agency proposed that the one-time notification requirement 
    would not apply to lab packs. Under the LDR program, a generator of a 
    lab pack can either meet the treatment standards and paperwork 
    requirements for all the hazardous wastes included in the lab pack, or 
    meet the streamlined lab pack requirements of Sec. 268.42 and the 
    paperwork requirements of Sec. 268.7(a)(9) (old Sec. 268.7(a)(8)). 
    Several commenters disagreed with the proposed approach, stating that 
    while lab packs can be highly variable in hazardous waste content, 
    there are instances where routine and consistent lab packs are shipped 
    by generators on a regular basis. It was also pointed out that if the 
    lab pack generator decided to meet the treatment standards of each 
    waste in the lab pack rather than the Sec. 268.42 alternative lab pack 
    standards, it would be allowable to produce a one-time notification for 
    each waste the lab pack contained. Therefore, it did not seem equitable 
    to make a lab pack generator that chose to use the alternative lab pack 
    standards produce a notification for each shipment, while a lab pack 
    generator meeting the treatment standards for each hazardous waste in 
    the lab pack could produce one-time notifications for each waste, so 
    long as their waste, process or receiving facility did not change. 
    Therefore, EPA has decided to change its proposed approach, and is 
    including generators of lab packs in the one-time notification 
    provisions of this final rule.
        Furthermore, the lab pack notification requirements of 
    Sec. 268.7(a)(8) are streamlined in today's rule to include only the 
    requirements of Secs. 268.7(a)(2), 268.7(a)(6), and 268.7(a)(7). This 
    is possible because the alternative treatment standard for lab packs 
    specifies a method of treatment rather than concentration levels that 
    would have to be monitored after treatment. There is, therefore, no 
    need to know whether the wastes in the lab packs are wastewaters or 
    nonwastewaters or are hazardous debris (these are the data items being 
    deleted from the lab pack notification).
        In Sec. 268.7(a)(3), the Agency is changing the notification 
    requirement so that a generator whose waste meets the appropriate 
    treatment standards as generated is only required to submit a one-time 
    notification and certification to the receiving facility. The 
    requirements for this one-time notification and certification are much 
    the same as those discussed above.
        In Sec. 268.7(a)(5), EPA is removing the requirement that 
    generators treating on-site in tanks or containers have to submit waste 
    analysis plans to States and Regions. Instead, the plans must merely be 
    kept in their on-site files, as proposed.
        The Agency is changing the record retention time period in 
    Sec. 268.7(a)(8) from five to three years, in order to make LDR 
    requirements consistent with other RCRA record retention periods.
        Under Sec. 268.7(b)(4), the treatment facility is only required to 
    submit a one-time notification and certification to the receiving 
    facility, rather than submit one with each shipment of waste. A copy of 
    the notification and certification must be kept in the treatment 
    facility's files. If the waste, treatment system, or the receiving land 
    disposal facility changes, the treatment facility must send a new 
    notification and certification to the land disposal facility, and place 
    a copy of these records in their files. Furthermore, the treatment 
    facility notification requirements have been consolidated into a table 
    at Sec. 268.7(b)(4).
        Finally, the Agency wishes to clarify that any records kept in 
    connection with the LDR program may be stored electronically, 
    eliminating the need to actually maintain paper copies. EPA wants to 
    encourage electronic storage of LDR notifications. However, because of 
    the complex issues involved in electronic data interchange (EDI), EPA 
    cannot at this time include standards for electronic storage of LDR 
    notifications in this final rule. The Agency may develop those 
    standards at a future date. Until such general standards for allowing 
    electronic storage of information are developed, EPA would note that it 
    has, on one occasion, confirmed that the use of an image scanning 
    system developed by Safety Kleen Corporation was sufficient to meet 
    hazardous waste manifest recordkeeping requirements (see attachment to 
    the letter to Catherine A. McCord in the docket). This system was used 
    to scan, store, and retrieve images of original hazardous waste 
    manifests with handwritten signatures. Although the letter confirmed 
    only that Safety Kleen's system met these requirements, the Agency 
    noted that similar systems used by others might also be able to meet 
    RCRA requirements.
    
    B. Clean-up of LDR Requirements in 40 CFR 268
    
        EPA is rewriting portions of the LDR regulations to help the 
    regulated community understand better what they
    
    [[Page 26005]]
    
    are required to do to comply with today's rule. Clean-up tasks such as 
    removing extraneous cross references, eliminating unneeded language, 
    removing unneeded appendices, and other similar actions have been taken 
    to eliminate confusion for the regulated community. A noteworthy change 
    is the elimination of the California List requirements that were 
    promulgated in 1987, because they have been superseded by more specific 
    treatment standards. In addition, a clarification has been made at 40 
    CFR 268.1(e) that the de minimis provision applies to characteristic 
    wastes as well as commercial chemical products and intermediates.
    1. Section 268.1
        Section 268.1(e)(4) is clarified so that the de minimis provision 
    applies to minor losses of characteristic wastes as well as to minor 
    releases of commercial chemical products and intermediates. EPA 
    actually made this clarification already in the Phase III final rule 
    (see 61 FR at 15597), but inadvertently omitted it from the Phase III 
    withdrawal notice (see 61 FR 15662). The withdrawal notice should have 
    removed paragraph 268.1(e)(4)(ii) only, because it dealt with the 
    special de minimis provisions for characteristic wastes being injected 
    into Class I injection wells (and thus, subject to the Land Disposal 
    Program Flexibility Act of 1996, the impetus for the withdrawal notice. 
    See 61 FR 15661). A typographical error made it appear that the entire 
    paragraph (e) was being withdrawn, which was not the intention of the 
    Agency. Therefore, today's regulatory language contains the text of 
    268.1(e) in its entirety, and clarifies that the de minimis provision 
    applies to characteristic wastes.
    2. Section 268.4
        Section 268.4(a)(2)(iv) is changed to read, ``Recordkeeping. The 
    sampling, analysis, and recordkeeping provisions of Secs. 264.13 and 
    265.13 apply.'' Referencing the Secs. 264.13 and 265.13 requirements in 
    Sec. 268.4 clarifies that there are no additional recordkeeping 
    requirements at Sec. 268.4; the general facility recordkeeping 
    requirements apply, thus the LDR program does not add additional 
    burden.
    3. Section 268.5
        The Agency proposed to amend Sec. 268.5(e) so that an applicant 
    could apply for and be granted additional time (up to one year) when 
    first applying for a case-by-case extension of the effective date. 
    Commenters argued, however, that it would be inappropriate for EPA to 
    grant what would be, in effect, a ``two-year'' case-by-case capacity 
    variance. Some commenters stated that the proposed change would hinder 
    necessary treatment capacity from being brought on-line expeditiously, 
    and that requiring a renewal application for a second-year extension 
    allows the Agency to evaluate whether the applicant has made a good-
    faith effort to develop or locate hazardous waste treatment capacity. 
    The Agency is persuaded by the commenter's concerns and is, therefore, 
    not making the proposed change to Sec. 268.5. As has always been the 
    case in the LDR program, case-by-case extension applicants must make a 
    separate application for a renewal of their case-by-case extension if 
    the initial one-year period is not sufficient to develop treatment 
    capacity.
    4. Section 268.7
        In section 268.7(c)(2), the sentence, ``* * * test method described 
    in appendix I of this part or using any methods required by generators 
    under Sec. 268.32 of this part * * *'' is changed to read, ``* * * test 
    method described in `Test Methods for Evaluating Solid Waste, Physical/
    Chemical Methods,' EPA Publication SW-846.'' Specific reference to EPA 
    Publication SW-846 for the Toxicity Characteristic Leaching Procedure 
    gives the regulated community a more direct reference for details of 
    the test method.
    5. Section 268.9
        In Sec. 268.9, paragraph (a) has been clarified to better describe 
    how wastes should be identified for purposes of the LDR program when 
    they are both listed and characteristic hazardous wastes.
        In Sec. 268.9(d)(1)(ii), the language has been edited to clarify 
    that if all underlying hazardous constituents reasonably expected to be 
    present in a characteristic waste will be monitored, then the generator 
    need not list any of them on the LDR notification. If, on the other 
    hand, a subset of all underlying hazardous constituents will be 
    monitored, they must be included on the LDR notification.
    6. References to Section 268.32
        References to Sec. 268.32 and RCRA 3004(d), California List wastes, 
    are removed, because the treatment standards for the these wastes have 
    been superseded by subsequent treatment standards. See generally 55 FR 
    at 22675 (June 1, 1990) noting the general principle that California 
    list prohibitions no longer apply once a more specific treatment 
    standard applies, and noting the handful of situations where California 
    list prohibitions would continue to apply. With the advent of the 
    requirement to treat for underlying hazardous constituents reasonably 
    expected to be present in characteristic wastes, there no longer are 
    any situations where California list prohibitions could create an 
    exclusive treatment standard. Consequently, there is no need to retain 
    any reference to California list prohibitions in the regulations.
    7. Sections 268.34-268.37
        The information about the dates of waste prohibition provided in 
    Secs. 268.34-268.37 is removed because the treatment standards for the 
    wastes are all now in effect, eliminating any need to retain the dates.
    8. References to Sections 268.41-268.43
        References in Part 268 to LDR treatment standards that have 
    previously been found in tables in Secs. 268.41, 268.42, and 268.43, 
    are changed to refer to the consolidated table in 268.40.
    9. Appendices
        Appendix I is removed and reserved because the TCLP test method 
    reference to SW-846 will be incorporated into the text of the 
    regulatory language.
        Appendix II to Part 268 is also removed and reserved because it 
    incorrectly refers to treatment standards in Secs. 268.41, 268.42, and 
    268.43 (they are now in Sec. 268.40); furthermore, there is no longer a 
    need for a reference to the solvent treatment standards.
        Appendix III is removed and reserved because the California List 
    treatment standards have been superseded by Universal Treatment 
    Standards plus the requirement to treat underlying hazardous 
    constituents in characteristic hazardous wastes. Thus, there is no need 
    for a listing of halogenated organic compounds under the California 
    List.
        Appendix VI is amended to clarify that land disposed characteristic 
    wastes that also contain underlying hazardous constituents must be 
    treated not only by a ``deactivating'' technology to remove the 
    characteristic, but also treated to achieve the Universal Treatment 
    Standard for underlying hazardous constituents.
        Appendix VII has been updated to include all the effective dates of 
    all surface disposed hazardous wastes for which there are treatment 
    standards. Likewise, Appendix VIII has been updated.
        Appendix X is removed and reserved because it summarized paperwork 
    requirements that are clarified in tables in today's rule at sections 
    268.7(a) and (b).
    
    [[Page 26006]]
    
        The Agency is committed to identifying new ways the LDR program can 
    be simplified, and will continue to seek additional opportunities for 
    such streamlining efforts in the future.
    
    C. Clarifications of Point of Generation
    
        Summary: EPA is identifying the point of generation of wastes from 
    boiler cleanout and for certain ignitable wastes treated in tanks. The 
    significance of this action is to define the point at which a 
    determination is made as to whether or not the LDR prohibitions attach 
    to the wastes generated from these activities. In some cases, the 
    broader question of whether a hazardous waste is even generated also 
    can be presented. A waste which is not identified or listed as 
    hazardous at the point LDR prohibitions would attach, the so-called 
    ``point of generation'' is not prohibited from land disposal. 
    Conversely, if a waste is hazardous (i.e. identified or listed) at that 
    point, LDR prohibitions typically do attach notwithstanding that the 
    waste may no longer be ``hazardous'' at the point it is land disposed. 
    EPA is not finalizing options discussed in the Phase III LDR rule (60 
    FR 11715, March 2, 1995) which discussed more far-reaching alternatives 
    for defining the point at which LDR prohibitions can attach, but is 
    issuing interpretations applicable to several discrete fact situations 
    involving questions implicating this issue.
    1. General Discussion
        Since November 1986, EPA has required determinations as to whether 
    LDR prohibitions attach to be made at the point when hazardous wastes 
    are generated (51 FR 40620). This issue took on critical import in the 
    so-called Third Third rule when EPA addressed the issue of treatment 
    standards for wastes that exhibit a hazardous waste characteristic, and 
    whether LDR prohibitions could apply to wastes that initially exhibit a 
    characteristic but no longer do so (i.e. are ``non-hazardous'' in that 
    they are no longer identified or listed as hazardous) at the point they 
    are land disposed. By adhering to the principle that LDR prohibitions 
    attach at the point of waste generation, EPA maintained that these de-
    characterized wastes must still be treated to satisfy EPA-established 
    treatment standards, notwithstanding that the wastes are no longer 
    identified as hazardous. 55 FR at 22651-52. The D.C. Circuit sustained 
    this interpretation as permissible in Chemical Waste Management v. EPA, 
    976 F.2d 2, 13-14 (D.C. Cir. 1992) cert. denied 113 S. Ct. 1961 (1993).
        In the Phase III LDR rule, EPA solicited comment on the issue of 
    possibly redefining the point at which LDR prohibitions attach. EPA 
    presented three options: (1) when there are similar wastewater streams 
    generated by similar processes; (2) when there are waste streams from a 
    single process; and (3) at a point of aggregation called ``battery 
    limits.'' 60 FR 11715-717.
        EPA considered these options because of the potential reach of the 
    Chemical Waste Management opinion on generally successful wastewater 
    management operations carried out pursuant to the Clean Water Act (i.e. 
    treatment of aggregated wastewaters, some of which at one time 
    exhibited a hazardous waste characteristic, pursuant to the National 
    Pollutant Discharge Elimination System regulations for direct 
    dischargers and pretreatment regulations for indirect dischargers) and 
    the Safe Drinking Water Act (injection of decharacterized wastewaters 
    into Class I non-hazardous injection wells under the Underground 
    Injection Control program). However, on March 26, 1996, President 
    Clinton signed into law the Land Disposal Program Flexibility Act of 
    1996. This Act provided, among other things, that decharacterized 
    wastes managed in the types of wastewater management systems described 
    above are no longer prohibited from land disposal so long as they are 
    not hazardous wastes at the point they are land disposed. See generally 
    61 FR 61660 (April 8, 1996). As a result, EPA no longer believes there 
    is any need to fundamentally reexamine the issue of where LDR 
    prohibitions attach, and is not acting on these parts of the Phase III 
    proposal.
        However, the Agency has identified specific issues which may be 
    considered ``point of generation'' issues, and which were not addressed 
    by the Land Disposal Program Flexibility Act of 1996. In today's rule, 
    EPA is addressing these specific issues. In each case discussed below, 
    the Agency believes that the existing regulatory language is adequate, 
    but clarification is necessary to prevent inappropriate 
    interpretations. In making these interpretations, EPA is in some cases 
    clarifying not only LDR applicability, but also generally where the 
    determination as to whether a waste is hazardous must be made.
    2. Boiler Cleanout
        Power plant boilers are generally taken out of service and cleaned 
    out once every 3 years (an average of one unit every year per 
    facility). The cleaning process generally consists of an initial rinse 
    of an acid cleaning solution and one or two rinses of water, generating 
    an average of several hundred thousand gallons of acid wash/rinse water 
    during each cleaning. The initial rinsate stream frequently is 
    characteristically hazardous, exhibiting the TC for lead and chromium 
    plus the characteristic of corrosivity.
        The rinsate from this process is combined in a tank (or 
    potentially, several tanks), usually temporary tanks brought on-site 
    for the cleaning process, and then either discharged to surface 
    impoundments prior to NPDES discharge (which commingled wastes would 
    normally be exempt from RCRA Subtitle C by virtue of the Bevill 
    Amendment) or directly fed to the boilers (a practice typically raising 
    no issues of LDR applicability since no land disposal is involved). The 
    issue in question is whether waste is considered generated after each 
    rinse (acid and water) or at the end of the cleaning of the boiler when 
    the rinsates have been combined; in other words, whether a 
    determination is made for each rinse or for combined rinses. If the 
    latter, then the rinsate would be hazardous waste (and as one 
    consequence, potentially prohibited from land disposal) only if the 
    combined rinsates exhibit a characteristic. Note that this is not 
    strictly an LDR issue but presents the issue of whether a unit is 
    regulated, in this case the tank that receives the rinsate.
        The Agency is today clarifying that, specific to power plant boiler 
    cleanout (and potentially, to other sporadic cleaning activities 
    involving multiple rinses), generation is at the completion of the 
    entire cleanout process. EPA believes that the mass loading of 
    hazardous constituents from the process to the environment will not be 
    affected by this determination, since a given amount of cleanout fluid 
    and water is needed to complete the task in every case. Cf. 60 FR at 
    11716 noting that in such situations the underlying policy of the 
    prohibition on dilution is not implicated. The agency views the 
    cleanout of the boilers as one process and therefore does not consider 
    the mixing of acid rinse and water rinse as impermissible dilution but 
    as a single waste rinsate resulting from the single cleanout process. 
    This waste is subject to regulation if it exhibits a characteristic, 
    and subject to LDR prohibitions if it exhibits a characteristic and is 
    going to be land disposed.
        Today's clarification of the point of generation for boiler 
    cleanout is limited to the situation in which the entire quantity of 
    boiler cleanout rinses are contained in a single container so that 
    hazardous waste and LDR determinations can be made based upon the 
    commingling of all the rinses
    
    [[Page 26007]]
    
    together. If, for example, a temporary tank is brought on-site but does 
    not have sufficient capacity to handle the estimated several hundred 
    thousand gallons of rinsate at once, the waste will likely have to be 
    managed in separate loads. In such instances, the generator will still 
    be required to make hazardous waste and LDR determinations for each 
    separate load.
        In adopting today's interpretation, EPA emphasizes that this type 
    of cleaning is a batch operation occurring at widely-spaced intervals 
    and involving temporary storage units (i.e. units that are removed from 
    the premises after receiving the rinsate). Thus, the interpretation 
    does not ever apply where a surface impoundment receives rinsate (see, 
    e.g., Chemical Waste Management v. EPA, 976 F. 2d at 20 n. 4 (placement 
    of any amount of characteristic waste in a surface impoundment makes 
    the unit a regulated unit even if diluted to non-characteristic levels 
    afterwards)). The interpretation also does not apply where there are 
    permanent storage units involved. EPA also notes the evident point that 
    if commingled rinses still exhibit a hazardous waste characteristic, 
    the receiving tank is a regulated unit. Persons owning or operating 
    such tanks have the same obligations as other generators to determine 
    whether the waste exhibits a characteristic. See 262.11.
    3. Sludge From High TOC (Total Organic Carbon) D001 Treated in Tank 
    Based Systems
        Many generators introduce waste into tank-based wastewater 
    treatment systems where the resulting effluent is discharged to a POTW 
    or to navigable waters, and the resulting wastewater treatment sludge 
    is land disposed. At times, the waste that is placed in the tank-based 
    system exhibits the ignitable characteristic. If the organic content of 
    the wastewater is sufficiently high, the liquid waste--when first 
    released--can meet the definition of nonwastewater found in 40 CFR Part 
    268.2(d).
        The fact situation of concern can involve releases of high TOC 
    ignitable wastes (which have a designated method of treatment), raising 
    a question of whether that treatment standard for high TOC waste still 
    applies to sludge generated from the wastewater treatment, even if the 
    sludge is not itself high TOC ignitable waste.
        It is EPA's view that the sludge in this situation should be viewed 
    as a new treatability group. Put another way, the change of 
    treatability group principle applies to situations where liquid wastes 
    which are technically nonwastewaters are inadvertently placed in 
    wastewater treatment systems in small quantities, for legitimate 
    wastewater treatment, thereupon becoming wastewaters (as defined in 
    268.2(f) of the rules), and subsequently generating a sludge. See 58 FR 
    29871, May 24, 1993 (``In the Third Third final rule, EPA stated that 
    for characteristic wastes, each change of treatability group in a 
    treatment train marked a new point of generation for determining if a 
    characteristic waste was prohibited from land disposal''). 
    Consequently, because the sludge generated from the tank-based 
    wastewater treatment system is a different treatability group from the 
    wastewater from which it is generated, it would be considered to be a 
    newly generated waste that should be evaluated at its point of 
    generation to determine if it is hazardous, and if so, to then 
    determine the appropriate LDR standard. (Also, please note that 
    elsewhere in today's notice the Agency clarifies that the LDR de 
    minimis exemption applies to small, inadvertent, releases of 
    characteristic waste into wastewater treatment systems. As a practical 
    matter, the de minimis exemption probably makes the question moot, 
    because larger releases would not typically occur since they would 
    likely interfere with wastewater treatment systems operation.)
    4. Tank Rinsate
        An issue arises when high-TOC ignitable wastes are stored in tanks, 
    and some residue from these wastes remains in the tanks after the tanks 
    are emptied and rinsed. The initial high-TOC ignitable waste is 
    considered a nonwastewater with the treatment standard of CMBST 
    (combustion) or RORG (recovery of organics). However, it is EPA's view 
    that the rinsate from an empty tank (see 47 FR 1250, January 11, 1982, 
    for guidance on empty waste tanks) is a newly generated wastewater and 
    the high-TOC ignitable waste treatment standards do not attach. The 
    rinsate must be evaluated at its point of generation, i.e., after the 
    complete rinsing of the empty tank, and, if it exhibits a 
    characteristic (or for some reason is listed independently) it is 
    subject to treatment standards for that characteristic (or listed 
    waste), rather than to the form of the waste from which it originated. 
    This determination also applies to tanks that are used to collect 
    wastewaters that are listed solely because they exhibit a 
    characteristic (i.e., ignitability, corrosivity, or reactivity). EPA 
    has stated that the existing rule, which provides that the dilution 
    prohibition does not apply to wastewaters listed solely because they 
    exhibit a characteristic, remains in effect. See 61 FR 15662.
    
    D. POLYM Method of Treatment for High-TOC (Total Organic Carbon) 
    Ignitable D001 Wastes
    
        Summary: Today's rule establishes an alternative treatment standard 
    of POLYM (polymerization) for high-TOC D001 wastes originally intended 
    as chemical components in the commercial manufacture of plastics. In 
    the polymerization treatment process (POLYM), the wastes are reacted to 
    produce a chemically stable plastic in the same manner that commercial 
    plastics are formed.
        Discussion: The National Marine Manufacturer's Association 
    contacted EPA with concerns that the May 1993 Interim Final Rule 
    prohibited the practice of polymerizing excess polyester/styrene waste 
    left over from the manufacture of modular shower stalls and 
    recreational boats, among other things. EPA proposed to add 
    polymerization (POLYM) to the set of required methods of treatment 
    designated as BDAT for high-TOC ignitable (D001) wastes resulting from 
    commercial polymerization processes. (60 FR 43679, August 22, 1995.) In 
    these manufacturing processes, polyester/styrene reacts with methyl 
    ethyl ketone (MEK) peroxide in a mold to form fiberglass. The ignitable 
    waste polyester/styrene and MEK peroxide are the wastes of concern.
        Small quantities of polyester/styrene monomers and MEK peroxide 
    wastes can be reacted together to create fiberglass scraps. The scraps 
    are inert and do not exhibit the hazardous waste characteristics of 
    toxicity, ignitability, corrosivity, or reactivity. It is this practice 
    that is referred to as polymerization for the purposes of this rule. 
    The waste polyester/styrene monomers and MEK peroxide are currently 
    regulated as high-TOC ignitable wastes (40 CFR 268.9) for which the 
    current standard is treatment by CMBST (combustion) or by RORGS 
    (recovery of organics) before land disposal. Neither CMBST nor RORGS 
    allows for polymerization (as an exclusive treatment method) of high-
    TOC ignitable wastes. The Agency believes that the practice of 
    polymerizing high-TOC ignitable waste polymers and monomers which are 
    chemical components in the manufacture of plastics to a 
    noncharacteristic inert mass adequately minimizes threats posed by 
    disposal of the waste.
        Today EPA is establishing POLYM as an alternative to CMBST or RORGS 
    only for those high-TOC D001 wastes
    
    [[Page 26008]]
    
    originally intended as chemical components in the commercial 
    manufacture of plastics. POLYM requires the addition of the same 
    polymerizing component or catalyst to the deactivated high-TOC D001 
    monomer stream intended for land disposal. POLYM is defined as 
    ``formation of complex high-molecular weight solids through 
    polymerization of monomers with high-TOC D001 nonwastewaters which are 
    chemical components in the manufacture of plastics.''
        EPA acknowledges that POLYM is not as effective at destroying all 
    of the hazardous constituents of the materials as CMBST, the specified 
    treatment standard for high-TOC D001 nonwastewaters. However, as 
    defined, POLYM is the same process that is used in the actual 
    manufacturing of plastic products such as water pipe and watercraft. To 
    allow materials and a process to be used to construct water pipe and 
    boat hulls, but prohibit the same process to be used to treat excess 
    materials from those same processes does not make sense. In addition, 
    the treatment of these chemical components using POLYM does convert an 
    ignitable waste into a non-ignitable solid prior to disposal. Treatment 
    occurs as the organic materials react to form a hard, inert material. 
    Data submitted by the Composites Institute (see CI Memo 20 DEC 96) show 
    that of the Appendix VIII constituents that are present in scrap 
    uncured polyester resins, greater than 50% of the constituents are 
    chemically converted by the polymerization process to form a part of 
    the solid polymer. The remaining constituents are physically bound in 
    the solid polymer matrix. The Agency believes that the low quantities 
    of Appendix VIII constituents are sufficiently bound in the polymer 
    matrix so as to minimize the threats posed by disposal of the 
    noncharacteristic inert mass of scrap material. Below is a table 
    showing the Appendix VIII constituents typically found in scrap uncured 
    polyester resins:

    Of the constituents listed in the table above, methyl methacrylate (a 
    monomer) and methyl ethyl ketone peroxide (a catalyst), are chemically 
    converted by the polymerization process and form part of the solid 
    polymer.
        EPA has decided to promulgate POLYM as a treatment standard rather 
    than dealing with this issue on an individual basis via Determination 
    of Equivalent Treatment (DET) petitions. As defined, equivalency need 
    not remove every single molecule of constituents as the comparison 
    technology to be considered equivalent. A similar issue involving high-
    TOC ignitable waste was addressed in a Determination of Equivalent 
    Treatment (see DET IBM Essex Junction, VT). In that determination, the 
    high-TOC waste was being treated to a slightly lower level than 
    combustion. EPA did so, in part, because the treatment process was 
    achieving very substantial destruction of hazardous constituents, and 
    otherwise assuring that the special concerns regarding treatment of 
    high-TOC ignitable wastes, such as interference with wastewater 
    treatment systems, were not present. Similarly, in this instance, POLYM 
    will destroy most of the hazardous constituents present and 
    substantially immobilize those that remain. In addition, there is no 
    possibility that this treatment method will interfere with wastewater 
    treatment. Finally, EPA notes that the POLYM process appears to be as 
    efficient as the other type of allowable treatment method for high-TOC 
    ignitable wastes, namely RORGS (recovery of organics). Thus, EPA 
    believes that the POLYM process evaluated here, along with CMBST and 
    REORG, satisfies the section 3004(m) requirement that threats be 
    minimized by treatment, and also could satisfy the equivalency standard 
    in 268.42(b).
        A number of commenters have solicited EPA to expand the definition 
    of POLYM to include other types of polymerization processes. EPA 
    appreciates the suggestions of the commenters. However, the Agency does 
    not currently have enough data to evaluate the effects of expanding the 
    definition. The Agency will consider the idea of expanding the 
    definition of POLYM and solicits any data that commenters may have 
    regarding additional methods of polymerization. Further, under 
    268.42(b), persons may petition the Agency for a determination of 
    equivalent treatment for their specific polymerization process, if it 
    is not included in today's rule.
        Finally, in response to inquiries, EPA notes that POLYM treatment 
    (or for that matter, most types of treatment) can occur at the site of 
    generation without having to obtain a RCRA permit, provided treatment 
    occurs in tanks, containers or containment buildings and these units 
    comply with the substantive standards set out in 40 CFR 262.34 
    (standards for so-called 90-day generator tanks, containers, and 
    containment buildings). See 51 FR at 10168 (March 24, 1986). EPA notes 
    further that these standards for 90-day units may include compliance 
    with the RCRA air emission standards set out in subparts AA, BB, and CC 
    of part 265 (assuming the waste satisfies the applicability criteria 
    set out in these rules). See generally, 61 FR at 59934-35 (Nov. 25, 
    1996) and 59 FR 62896 (Dec. 6, 1994). In addition, POLYM treatment 
    occurring in units requiring a permit could be subject to the 
    corresponding standards for air emissions found in Part 264 subparts 
    AA, BB and CC.
    
    E. Decision To Retain Current Treatment Standard for Multi-Source 
    Leachate (Waste Code F039)
    
        In the Phase IV proposed rule, EPA suggested that with the 
    promulgation of the Universal Treatment Standards (UTS), there was no 
    longer a need for the separate list of constituents for multisource 
    leachate (F039) in the Treatment Standards for Hazardous Wastes table 
    at 40 CFR 268.40. EPA proposed that F039 would be treated to meet all 
    the UTS for the constituents at Sec. 268.48, with the exceptions of 
    fluoride, vanadium, and zinc, which are not underlying hazardous 
    constituents.
        Several commenters, however, pointed out that such an action would 
    be more than a simplification of existing treatment standards. Rather, 
    it would add several constituents to those for which EPA has set 
    treatment standards in F039, without notice and an opportunity for 
    comment. The Agency has reexamined the F039 list of constituents and 
    agrees with commenters that changing F039 to cross reference the UTS 
    constituents at Sec. 268.48 would add regulated constituents to F039. 
    This was not the intent of the proposed change. Therefore, the Agency 
    is not promulgating any change to F039 in this final rule. The 
    treatment standard levels for the hazardous constituents in F039 are 
    identical to the UTS for those constituents, so retaining the current
    
    [[Page 26009]]
    
    treatment standard constituent list for F039 does not decrease 
    environmental protection in comparison with changing the standard.
    
    V. Status of Proposed Provisions on Leaks, Sludges, and Air Emissions 
    From RCRA-Equivalent Treatment of Decharacterized Wastewaters in Clean 
    Water Act Surface Impoundments
    
        In the August 22, 1995 Phase IV proposal, EPA discussed three 
    options for ensuring that underlying hazardous constituents in 
    decharacterized wastes were not released to the environment via leaks, 
    sludges, and air emissions from surface impoundments in systems 
    regulated by the Clean Water Act or Safe Drinking Water Act (60 FR 
    43655). (Decharacterized wastes are wastes which initially exhibited a 
    hazardous characteristic of ignitability, corrosivity, reactivity, or 
    toxicity when generated but are no longer characteristic). On March 16, 
    1996, the President signed the Land Disposal Program Flexibility Act of 
    1996, which provides that the wastes in question are no longer 
    prohibited from land disposal once rendered nonhazardous. As a result, 
    on April 8, 1996, EPA withdrew its treatment standards for these wastes 
    (61 FR 15660). Today EPA announces that it will not finalize, at this 
    time, the provisions for leaks, sludges, and air emissions that EPA 
    proposed on August 22, 1995 (60 FR 43655-43677). Furthermore, the 
    treatment standards for TC metal wastes discussed in the proposal 
    accompanying today's rule do not apply to TC metal wastes if the 
    characteristic is removed and the wastes are subsequently treated in a 
    unit whose discharge is regulated by the Clean Water Act or, for 
    underground injection wells, the Safe Drinking Water Act.
        However, the Land Disposal Flexibility Act does mandate EPA to 
    undertake a study to determine any potential risks posed by cross-media 
    transfer of hazardous constituents from these surface impoundments. The 
    findings of this study, begun by the Agency in April, 1996, may result 
    in proposed regulations for these units, if risks are in fact found 
    that would warrant such regulation.
    
    VI. Decision Not To Ban Nonamenable Wastes From Biological 
    Treatment
    
        EPA is not prohibiting certain decharacterized wastes from land-
    based wastewater treatment systems on the basis of whether the 
    constituents in those wastes are ``amenable'' to biological treatment. 
    As is discussed in the April 8, 1996 partial withdrawal notice to the 
    LDR Phase III final rule (61 FR 15660), the Land Disposal Program 
    Flexibility Act of 1996, signed by the President on March 26, 1996, 
    provides that the wastes in question are no longer prohibited from land 
    disposal once rendered nonhazardous. Because they are decharacterized 
    before they enter the impoundment, these wastes are no longer 
    prohibited wastes under RCRA.
    
    VII. Capacity Determinations for Wood Preserving Wastes
    
    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 details of the capacity analysis for each 
    group of wastes covered in this rule, see ``Background Document for 
    Capacity Analysis for Land Disposal Restrictions, Phase IV--Wood 
    Preserving Wastes (Final Rule).''
        In general, EPA's capacity analysis focuses 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., wastewater managed only in RCRA exempt tanks, with direct 
    discharge to a Publicly Owned Treatment Works (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 as a 
    result of the LDRs. EPA attempts to subtract from the required capacity 
    estimates the 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).
    
    B. Available Capacity
    
        Available capacity was estimated for the three treatment technology 
    categories: combustion, stabilization, and wastewater treatment that 
    are expected to be used for the wastes in today's rule. (Numerous other 
    types of treatment also can meet the treatment standards for much of 
    these wastes, although the Agency did not find it necessary to estimate 
    the available capacity of these treatments. See the Background Document 
    for further information.)
    1. Thermal Treatment
        EPA estimates that there are less than 50,000 tons per year of soil 
    combustion capacity, approximately 144,000 tons per year of commercial 
    sludge/solid combustion capacity, and 886,000 tons per year of 
    commercial liquid combustion capacity available for Phase IV Wood 
    Preserving Wastes. This accounts for treatment facilities without 
    updated permits for the newly listed wastes or that likely will not 
    wish to accept the wastes for other reasons (e.g. dioxin/furan 
    monitoring requirements, low BTU, or other undesirable waste 
    characteristics).
    2. Stabilization
        EPA estimates that there are approximately 1.1 million tons of 
    available stabilization capacity, with most of it able to meet the 
    treatment requirements for the newly listed wood preserving wastes.
    3. Wastewater Treatment
        EPA estimates that there are approximately 37 to 47 million tons 
    per year of available wastewater treatment capacity. The various 
    treatment technologies that form the basis of this capacity are 
    routinely able to meet the treatment standards of the wood preserving 
    wastewaters.
    
    C. Required Capacity and Comparison With Available Capacity
    
        EPA estimates that very small quantities of wood preserving 
    wastewater (approximately 440 tons of organic wastewater and 13,000 
    tons of inorganic wastewater) will require alternative treatment 
    capacity in order to comply with the LDRs. EPA estimates that less than 
    10,000 tons of nonwastewaters (8,700 tons of organic nonwastewaters and 
    1,300 tons of inorganic nonwastewaters) will require alternative 
    treatment as a result of the LDRs.
        EPA believes that combustion, combustion followed by stabilization, 
    or stabilization will meet the treatment standards for nonwastewaters 
    of wood preserving wastes. For wastes with arsenic, although the basis 
    of the treatment for arsenic is vitrification, EPA believes that the 
    standard can also be met by stabilization. Also, in general, chemical 
    precipitation will meet the treatment standards for the inorganic 
    wastewater. EPA identified specific wastewater treatment technologies 
    that support UTS for these wastes and concluded that the wastewater
    
    [[Page 26010]]
    
    treatment practices at the wood preserving facilities can be optimized 
    to meet the proposed limits. (Please see BDAT Background Document for 
    details.) There is sufficient liquid and sludge/solid combustion 
    capacity for both the organic wood preserving wastewaters and 
    nonwastewaters. In addition, EPA believes that there is sufficient 
    chemical precipitation capacity for the inorganic wastewater. Finally, 
    ample stabilization capacity exists for the inorganic nonwastewaters. 
    Therefore, EPA is not granting a variance for the newly listed wood 
    preserving wastes.
        Some commenters provided data on soil and debris contaminated with 
    wood preserving wastes. The regulated communities are quite concerned 
    about the availability of treatment capacity using established 
    technologies as well as the potential for innovative technologies to 
    provide additional treatment capacity. EPA has examined the available 
    data and information submitted by commenters and from other sources 
    such as Superfund Record of Decisions. The Agency estimated that 
    combustion capacity available to treat soils and debris contaminated 
    with newly listed wood preserving wastes is less than 50,000 tons per 
    year. In contrast, EPA estimates that well over 100,000 tons per year 
    of soil and debris may require additional combustion capacity. 
    Furthermore, logistics issues may severely hamper the ability of site 
    managers to obtain adequate alternative treatment in the near term. 
    Therefore, given the lack of available capacity and other issues 
    associated with soil and debris contaminated with F032, F034, and F035 
    wood preserving wastes, EPA is granting a two-year extension of the 
    effective date for these wastes.
    
    D. Mixed Radioactive Wastes
    
        Despite the uncertainty about quantities of mixed radioactive 
    wastes that will require treatment as a result of today's rule, any new 
    commercial capacity that becomes available will be needed for mixed 
    radioactive wastes that were regulated in previous LDR rulemakings and 
    whose capacity extensions have already expired. Thus, EPA has 
    determined that sufficient alternative treatment capacity is not 
    available, and is granting a two-year national capacity extension of 
    the effective date for radioactive wastes mixed with RCRA wastes for 
    which standards are being promulgated today, including soil and debris.
    
    E. Phase IV Wood Preserving Wastes Injected Into Underground Injection 
    Control (UIC) Class I Wells Injected Into Class I Wells
    
        EPA estimated the volume of waste regulated in today's rule that is 
    currently injected into UIC wells. This volume is a conservative 
    estimate based on highly complex non-segregable waste stream mixtures, 
    and it may be that the actual volume injected is less. A very small 
    volume of newly listed wood preserving wastes (F032, F034 and F035) may 
    be injected into Class I Wells. These wastes are either injected at 
    wells located at the site of generation, or are sent off-site for 
    injection in commercial Class I wells.
        These wells have existing no-migration determinations. However, 
    even if an injection well has received a no-migration petition, it can 
    inject a newly prohibited waste only if the waste is similar to wastes 
    included in the initial no-migration petition. The new wastes must 
    behave hydraulically and chemically in a similar manner to those 
    already included in the initial petition demonstration such that they 
    will not interfere with the containment capability of the injection 
    zone and the location of the waste plume will not significantly differ 
    from the initial demonstration. (See 40 CFR 148.20 (f) , and UIC 
    Guidance No. 74.) Based on these principles, EPA has investigated 
    whether the no-migration determination for the wells injecting these 
    wood preserving wastes allow continued injection. If injection is not 
    presently allowed due to the need to amend a petition, the well would 
    not be providing any capacity, because none of these facilities operate 
    treatment processes capable of achieving the treatment standard for 
    these wastes.
        EPA has determined that at least six commercial injection well 
    facilities with no-migration petitions would be allowed to inject wood 
    preserving wastewaters without needing to amend their petitions. The 
    rationale for this determination is located in the RCRA docket. EPA has 
    further determined that these wells have unused injection capacity 
    exceeding the amount of wood preserving waste generated annually (EPA 
    Regional communications in the RCRA docket). Thus, even if all wood 
    preserving wastewaters presently injected would have to find new 
    capacity, sufficient capacity exists. In addition, there is commercial 
    wastewater treatment capacity that could accommodate some of this 
    volume.
        Based on this information, the Agency has reassessed its position 
    since the proposed rule and decided not to grant a two-year national 
    capacity extension of the effective date for wood preserving waste 
    being injected at Class I facilities. As discussed above, there appears 
    to be sufficient protective disposal capacity (i.e. approved no-
    migration disposal capacity) which can accommodate all of the 
    currently-injected wood preserving wastewaters, even if all this 
    wastewater will be diverted from injection wells currently used.
        EPA notes further that commenters did not claim that there was 
    insufficient capacity to manage these wastes. However, it should be 
    noted that RCRA section 3004(h)(3) provides individual facilities 
    opportunity to demonstrate that inadequate protective treatment or 
    disposal capacity is available. Substantive standards are set out in 40 
    CFR Sec. 268.5 and in UIC Guidance No. 69.
    
    F. Summary of Variance Determinations
    
        Table 1 lists each category of RCRA wastes for which EPA is today 
    setting LDR standards. For each category, this table indicates whether 
    EPA is granting a national capacity extension of the effective date for 
    land-disposed wastes or injected wastes managed by UIC Class I 
    injection wells.

    VIII. Changes to Definition of Solid Waste to Exclude Processed Scrap 
    Metal and Shredded Circuit Boards From RCRA Jurisdiction
    
        Summary: As proposed on January 25, 1995 (FR 61 2338), EPA is today 
    amending the definition of solid waste to exclude from RCRA 
    jurisdiction two types of materials: processed scrap metal and 
    containerized shredded circuit boards.
    
    A. Processed Scrap Metal
    
    1. Summary of Proposal
        The Agency proposed the exclusion of processed scrap metal and 
    shredded circuit boards being recycled from the Definition of Solid 
    Waste in the January 25, 1996 proposed Phase IV LDR supplemental 
    rulemaking. Currently, scrap metal being reclaimed is a solid waste, 
    but completely exempt from RCRA Subtitle C regulations. The proposal 
    would have amended the definition of solid waste to exclude processed 
    scrap metal and containerized shredded circuit boards that are being 
    recycled from RCRA jurisdiction. In the proposal, the Agency did not 
    propose to make changes to the current definition of scrap metal: 
    ``bits and pieces of metal parts (e.g., bars, turnings, rods, sheets, 
    wire) or metal pieces that are combined together with bolts and 
    soldering (e.g., radiators, scrap automobiles, railroad box cars), 
    which when worn or superfluous can be recycled.''
        The proposal defined processed scrap metal as ``scrap metal which 
    has been manually or mechanically altered to either separate it into 
    distinct materials to enhance economic value or to improve the handling 
    of materials. Processed scrap metal includes but is not limited to 
    scrap metal which has been bailed, shredded, sheared, melted, 
    agglomerated (for fines, drosses and related materials which are not 
    scrap metal prior to agglomeration) or separated by metal type.'' The 
    Agency believes that processed scrap metal being recycled is distinct 
    from other secondary materials defined as wastes when recycled due to 
    established markets for the material's utilization, inherent positive 
    economic value of the material, the physical form of the material, and 
    absence of damage incidents attributable to the material, and is 
    therefore sufficiently product-like that maintaining RCRA regulatory 
    jurisdiction over this material is not necessary. A summary of the 
    proposed exclusion from the definition of solid waste for shredded 
    circuit boards being recycled follows the discussion of the exclusion 
    from the definition of solid waste for processed scrap metal being 
    recycled.
    2. Modifications to the Proposal
        The Agency received approximately twenty-five comments concerning 
    the proposed scrap metal and shredded circuit board exclusions. The 
    comments were generally supportive of the exclusions. A background 
    document, the major comments received, and Agency responses on the 
    proposed processed scrap metal exclusion can be found in the docket for 
    this rulemaking. Comments on the shredded circuit board exclusion can 
    also be found in this background document.
        In response to comment on the proposed exclusion to the definition 
    of solid waste for processed scrap metal being recycled, the Agency has 
    made several modifications to the exclusion in the final rule. First, 
    the Agency has expanded the exclusion to cover unprocessed home and 
    unprocessed prompt scrap metal being recycled. Home scrap is scrap 
    metal generated by steel mills, foundries, and refineries such as 
    turnings, cuttings, punchings, and borings. Prompt scrap, also known as 
    industrial or new scrap metal, is generated by the metal working/
    fabrication industries and includes such scrap metal as turnings, 
    cuttings, punchings, and borings. These categories of scrap metal do 
    not fit the definition of processed scrap metal found in the proposal 
    because they often do not require a processing step before being sent 
    for recycling. The Agency evaluated unprocessed home scrap and prompt 
    scrap metal and found that these categories of scrap metal are 
    substantially similar to processed scrap metal due to established 
    markets for the material's utilization, inherent positive economic 
    value of the material, the physical form of the material, and absence 
    of damage incidents attributable to the material. Based on this 
    analysis, the Agency has expanded scope of the exclusion to include 
    both unprocessed home and unprocessed prompt scrap metal. In the final 
    rule, the term ``excluded scrap metal'' will be used to reflect this 
    decision. Commenters also suggested the Agency evaluate obsolete scrap 
    metal (scrap which is composed of worn out metal or a metal product 
    that has outlived it original use, such as automobile hulks, railroad 
    cars, aluminum beverage cans, steel beams from torn down buildings, and 
    household appliances) using the same factors. The Agency has not found 
    sufficient data to fully evaluate unprocessed obsolete scrap metal. 
    Therefore, in today's final rule the Agency is not expanding the scope 
    of the exclusion from the definition of solid waste to include obsolete 
    scrap metal. Providing an exclusion from the definition of solid waste 
    for obsolete scrap metal at this time would be premature and is better 
    addressed in the Definition of Solid Waste rulemaking, due to be 
    proposed in the near future.
        Second, the Agency clarifies that the exclusion for processed scrap 
    metal being recycled applies to scrap metal that has undergone a 
    processing step (as defined in the preamble to the proposed rule) 
    regardless of who does the processing. In other words, a processing 
    step may be performed by the generator, an intermediate scrap handler 
    (e.g. broker, scrap processor), or a scrap recycler. Once the scrap 
    metal has undergone a processing step, it may qualify for today's 
    exclusion.
        Third, the Agency has added chopping, crushing, flattening, cutting 
    and sorting, processes typically used in the processing of scrap metal 
    for recycling, to the definition of processed scrap metal in today's 
    final rule. In today's final rule, the definition of processing reads: 
    ``manually or physically altered to either separate it into distinct 
    materials to enhance economic value or to improve the handling of 
    materials. Additionally, to avoid confusion, the definition of 
    processed scrap metal has been reworded to clarify the status of 
    agglomerated fines, drosses and other related materials. Therefore, in 
    today's final rule, the category of processed scrap metal now includes 
    but is not limited to scrap metal which has been baled, shredded, 
    sheared, chopped, crushed, flattened, cut, melted, or separated by 
    metal type (i.e., sorted), and, fines, drosses and related materials 
    which have been agglomerated.'' Note that circuit boards that are 
    shredded and being sent for recycling are covered under the exclusion 
    from the definition of solid waste for shredded circuit boards being 
    recycled (261.4(a)(13)) see discussion following) and are not covered 
    under the definition of excluded scrap metal.
    
    B. Shredded Circuit Boards
    
    1. The Proposal
        In the proposed rule, EPA proposed to exclude shredded circuit 
    boards being reclaimed from the definition of solid waste in order to 
    facilitate their recovery. 61 F.R. 2339, 2361. The proposed exclusion 
    was conditioned on the storage of the shredded circuit boards in 
    containers prior to recovery that would be adequate to prevent a 
    release of the boards to the environment. This condition was
    
    [[Page 26012]]
    
    specified as a performance standard rather than a design standard to 
    allow the handler maximum flexibility in selecting the method of 
    containment. Today, EPA is finalizing this exclusion as proposed with 
    an additional limitation that shredded circuit boards excluded from 
    RCRA jurisdiction be free of mercury switches, mercury relays, nickel-
    cadmium batteries and lithium batteries.
    2. Exclusion for Shredded Circuit Boards Conditioned on Containerized 
    Storage Prior to Recovery
        EPA explained in the proposal that shredded circuit boards merit 
    exclusion from RCRA regulation in order to facilitate their recovery 
    when they are properly stored in containers to prevent their release to 
    the environment. As presented in the proposal, the necessity for the 
    proposed exclusion for shredded circuit boards is that the process of 
    shredding the circuit boards causes the boards to lose the scrap metal 
    exemption (see 40 CFR Sec. 261.6(a)(3)(ii)) that currently applies to 
    used whole circuit boards. This scrap metal exemption allows used whole 
    circuit boards being recycled to be shipped in commerce without being 
    subject to RCRA regulation including generator manifesting and export 
    requirements. The process of shredding the boards produces small fines 
    from the whole board which are dispersible and do not meet the RCRA 
    regulatory definition of scrap metal. The application of RCRA 
    regulatory provisions to shredded boards may present serious 
    disincentives to their recovery. As explained in the proposal, 
    generator manifesting and export requirements may result in significant 
    delays in shipments of shredded boards to recovery operations such as 
    smelters. Many intermediate precious metal reclaimers, e.g. shredders, 
    operate on a short cash flow and depend on prompt payment for shipments 
    of shredded circuit boards in order to pay the generators of the used 
    circuit boards for supplying them to the intermediate reclaimers.
        For the following reasons, EPA believes that shredded circuit 
    boards destined for reclamation when properly containerized and free of 
    mercury switches, mercury relays, nickel-cadmium batteries and lithium 
    batteries are an appropriate secondary material to be excluded from 
    RCRA regulation. As discussed in the proposal, shredding is beneficial 
    to the recovery process. Shredding improves the recovery of the boards 
    by improving handling of shredded boards through increasing the bulk 
    density of the boards in the container during shipment. Shredding also 
    improves the assaying of the shipment for base metal and precious metal 
    content by homogenizing the load thus assuring a representative sample 
    is taken for the assay. Shredding also destroys proprietary information 
    from generators or manufacturers of the boards thus better assuring 
    confidentiality to the generator or manufacturer when making a decision 
    to recycle. Some generators may be concerned about proprietary 
    information contained in used whole circuit boards being transferred to 
    competitors once the boards are out of the generator's control.
        Second, shredded boards have qualities which are similar to primary 
    materials such as virgin mineral concentrates that are processed and 
    refined for base metal and precious metal values. These qualities 
    satisfy the criteria EPA considers when evaluating whether a partially-
    reclaimed solid waste is commodity-like and is not part of the waste 
    management problem and thus is appropriate to exclude from RCRA 
    subtitle C jurisdiction through issuance of a variance. EPA believes 
    that these criteria are relevant in determining whether a general 
    exclusion is justified. See 40 CFR 261.30(c)& 261.31(c). These criteria 
    are: (1) The degree of processing the material has undergone and the 
    degree of further processing that is required, (2) the value of the 
    material after it has been reclaimed, (3) the degree to which the 
    reclaimed material is like an analogous raw material, (4) the extent to 
    which an end market for the reclaimed material is guaranteed, (5) the 
    extent to which a material is managed to minimize loss and (6) other 
    relevant factors (such as the presence of cyanide or other foreign 
    materials).
        Regarding the first criterion, shredded circuit boards have been 
    processed through shredders, hammer mills and similar devices to 
    decrease their size. Value is added to the boards, as indicated above, 
    because the boards are easier to handle, assay and ship without 
    concerns of generator confidentiality that might exist if the boards 
    were shipped to the smelters as whole boards. Further processing for 
    the shredded boards includes both smelting and refining to extract base 
    metals such as copper and precious metals such as gold, silver and 
    platinum group metals. And while a substantial amount of further 
    processing remains, EPA believes that shredded circuit boards can be 
    thought of as secondary feedstocks similar to primary ore concentrates 
    that have undergone beneficiation and are destined for primary mineral 
    processing and refining.
        Regarding the second criterion of the value of the material after 
    it has been reclaimed, shredded circuit boards generally have positive 
    economic value (i.e., the smelter pays the shredder for the assayed 
    base and precious metal value of the shipment). The typical price range 
    for shredded circuit boards is between a negative $0.25 per lb. and $5 
    per lb. One recycling company reported an annual average price of 
    shredded circuit boards of $1.50 per pound which is greater than the 
    current market price for refined copper metal.
        Regarding the third criterion of how the partially reclaimed 
    material compares to the analogous raw material, recyclers have 
    indicated that shredded circuit boards typically have assays of that 
    average 10 percent copper, between one-half and one-third that of 
    primary copper concentrates. Shredded circuit board copper assays 
    reported in literature evaluated in completion of this rule ranged 
    between 11 percent and 18 percent copper. Shredded circuit boards also 
    frequently contain precious metal values such as gold, silver or 
    platinum that enhance the economic value of the material. Moreover, the 
    reported recycling efficiency for copper, gold, silver and platinum 
    exceeds 90 percent for this type of material.
        Although toxic metal content for primary copper concentrates is 
    variable depending on the ore body it comes from, reported assays for 
    circuit boards are comparable in lead and lower in arsenic content than 
    reported primary copper concentrate assays. Although shredded circuit 
    boards are comparatively dispersible in comparison to primary copper 
    concentrates, the conditional requirement for the exclusion stipulates 
    that the shredded circuit boards must be stored in containers 
    sufficient to prevent a release to the environment prior to recovery 
    reduces any greater likelihood of release from shredded boards in 
    comparison to primary copper concentrates.
        The fourth criterion EPA uses to evaluate partially-reclaimed 
    secondary materials is the extent to which an end market is guaranteed 
    for the material. Continuous demand from primary smelters for base 
    metals and precious metals from shredded circuit boards should result 
    from the positive economic value of the boards, the relative ease of 
    handling and assaying of the boards and the diminishing quantities of 
    primary copper ore concentrates. According to the Bureau of Mines 
    Mineral Commodity Summaries 1994, reported and apparent
    
    [[Page 26013]]
    
    consumption for copper, silver and platinum group metals has either 
    remained constant or increased between 1989 and 1993. Reported 
    consumption of gold decreased slightly between 1989 and 1993 from 115 
    metric tons and 100 metric tons. Secondary gold production decreased 
    slightly over the same period from 158 metric tons to 130 metric tons. 
    The price of gold declined over the same period from $382 per troy 
    ounce to $355 per troy ounce. By 1996, the price of gold has increased 
    to over $380 per troy ounce.
        The fifth criterion EPA uses to evaluate partially-reclaimed 
    materials is the extent to which the material is managed to minimize 
    loss. The proposed exclusion is conditioned on the proper storage of 
    shredded circuit boards in containers prior to recovery. As mentioned 
    in the proposal, the shredded boards are usually stored in super sacks 
    (sacks that are reinforced woven resin and designed to accommodate bulk 
    shipments), gaylord containers (also known as tri-wall boxes composed 
    of three layers of cardboard with two layers of corrugation) and 55 
    gallon drums. Open bulk shipments of board by rail, truck or barge are 
    not within the scope of this exclusion. In addition to the storage 
    requirement, the economic value of the boards also provides an 
    incentive for handlers to prevent releases to the environment. At an 
    average market value of $1.50 per pound for one recycler, the incentive 
    to prevent releases is substantial. The Agency notes that 
    containerization in and of itself was not the only reason the Agency 
    concluded that shredded circuit boards should be excluded from the 
    definition of solid waste. The other five factors supported this 
    determination as well.
        Finally, EPA considers other relevant factors when evaluating the 
    exclusion of partially-reclaimed materials from RCRA jurisdiction 
    through the variance. In the context of shredded circuit boards, other 
    relevant factors include: (1) The presence of both materials possibly 
    attached to printed circuit boards that are ordinarily outside of the 
    definition of scrap metal such as mercury switches, mercury relays, 
    nickel-cadmium batteries and lithium batteries, and (2) the frequency 
    of foreign materials mixed with but not part of the circuit board 
    itself. EPA's concern about these materials is discussed below.
    3. Limitation on Mercury Switches, Mercury Relays, Nickel-Cadmium 
    Batteries and Lithium Batteries
        Printed circuit boards may contain or be incorporated into 
    electronic products which contain mercury switches, mercury relays, 
    nickel-cadmium batteries, and lithium batteries. EPA is concerned about 
    the potential environmental impact of these materials that are 
    associated with printed circuit board production and management after 
    the boards are spent. Ordinarily, commercial printed circuit board 
    recyclers, both intermediate processors (e.g. shredders) and smelters, 
    do not want mercury switches, mercury relays, nickel-cadmium batteries 
    and lithium batteries in shipments of shredded boards sent from the 
    intermediate processor to the smelter. However, because these items may 
    be very small, they may, on occasion, escape visual inspection and 
    become shredded along with printed circuit boards. When this happens, 
    EPA is concerned about the potential release of mercury or cadmium to 
    the environment. For this reason, EPA is limiting the scope of the 
    exclusion for shredded boards to shipments that are free of mercury 
    switches, mercury relays, nickel-cadmium batteries or lithium 
    batteries. Free of these materials means that mercury switches, mercury 
    relays, nickel-cadmium batteries and lithium batteries are not or have 
    not been part of the batch of circuit boards shredded to add value. In 
    addition, EPA reiterates that in enforcement actions that it is the 
    respondent in the action who bears the burden of proof in documenting 
    that a material for which an exclusion is claimed from the definition 
    of solid waste meets the appropriate regulatory definition or 
    exclusion. 40 CFR 261.2(f). Shredded circuit boards that are not free 
    of mercury switches, mercury relays, nickel-cadmium batteries, and 
    lithium batteries when reclaimed are solid wastes. This is so because 
    these used shredded circuit boards are spent materials. Spent materials 
    being reclaimed are solid wastes that, when they exhibit a 
    characteristic or are listed, are also hazardous wastes. 40 CFR 
    261.1(b)(1), 261.2(c)(3). As stated in the proposal, EPA established in 
    1992 that whole used circuit boards could be considered scrap metal. 
    The whole used circuit boards are therefore exempt from RCRA 
    regulation. See 40 CFR 261.6(a)(3)(ii) stating scrap metal being 
    recycled is exempt from RCRA regulation. (Please note that whole used 
    circuit boards which contain mercury switches, mercury relays, nickel-
    cadmium batteries, or lithium batteries also do not meet the definition 
    of scrap metal because mercury (being a liquid metal) and batteries are 
    not within the scope of the definition of scrap metal. See 50 F.R. 614, 
    624 (January 4, 1985).) As stated in the proposal shredded circuit 
    boards do not meet the definition of scrap metal because the shredded 
    material contains fines which are too small to qualify as scrap metal. 
    Shredded circuit boards that are not free of mercury switches, mercury 
    relays, nickel-cadmium batteries, and lithium batteries would be 
    subject to applicable parts of RCRA regulation, 40 CFR Parts 260 
    through 266, Part 268, Part 270, Part 273 and Part 124. Shredded 
    circuit boards with economically recoverable quantities of precious 
    metals are still eligible for conditional exemption from regulation 
    under 40 CFR Part 266 Subpart F. This provision allows recyclable 
    materials containing an economically recoverable amount of precious 
    metals to be exempt from many RCRA regulatory provisions. However, 
    these materials are still subject to manifesting, export and 
    speculative accumulation requirements. 40 CFR 266.70.
    4. Clarification of Regulatory Status of Secondary Materials Associated 
    With the Generation or Management of Circuit Boards
        Several commenters requested clarification in today's rule about 
    the current regulatory status of secondary materials associated with 
    the generation or management of printed circuit boards. These materials 
    include: spent solder baths (pot dumps), sweeps, baghouse dust, and 
    solder dross. These commenters also requested exclusion of these 
    materials from RCRA jurisdiction in today's rule.
        Spent solder baths, also known as pot dumps, are solidified pieces 
    of tin-lead solder baths used in the production of printed circuit 
    boards. Prior to 1993, EPA had classified spent solder baths as spent 
    materials, which, absent the scrap metal designation, would be fully 
    regulated under RCRA hazardous waste regulation. In 1993, EPA issued a 
    letter to the Lead Industries Association stating that spent solder 
    baths meet the definition of scrap metal and are therefore exempt from 
    RCRA regulation under the regulatory exemption for scrap metal being 
    recycled. This interpretation continues to be the Agency view.
        Sweeps refer alternatively to a powdered material that is a residue 
    of thermal recovery of precious metal-bearing secondary material (often 
    ash that is crushed into particulate form in a ball mill or similar 
    device) or particulate material that is collected from firms handling 
    precious metals such as jewelers and metal finishers. Sweeps have been 
    previously classified
    
    [[Page 26014]]
    
    by EPA as a by-product. 2 As such, when sent for 
    reclamation, sweeps are not solid waste and are excluded from RCRA 
    jurisdiction regulation when considered hazardous solely by exhibiting 
    a characteristic. Characteristic by-products are not solid wastes when 
    reclaimed. 40 CFR 261.2(c)(3). In contrast, when sweeps are derived 
    from source material that meets the description of a listed hazardous 
    waste, the sweeps are solid wastes that are also hazardous wastes and 
    are regulated under the appropriate RCRA regulation provisions. 40 CFR 
    261.2(c)(3). For example, often combustible material such as a rag, 
    filter or paper is used to clean up a secondary material such as a 
    spent solvent that may: (1) contain precious metals and (2) meets one 
    of the F001 through F005 listing descriptions for solvents. The rag, 
    filter or paper will be burned to an ash that it homogenized in order 
    to assay its precious metal content. The ash when crushed is turned 
    into a sweep. The sweep carries the F-listed hazardous waste code that 
    was associated with the original source material (i.e., solvent). 
    Listed by-products, in contrast to characteristic by-products, are 
    solid and hazardous wastes when reclaimed.
    ---------------------------------------------------------------------------
    
        \2\ August 26, 1992 memorandum from Sylvia K. Lowrance, 
    Director, U.S.E.P.A., Office of Solid Waste to Waste Management 
    Division Directors U.S.E.P.A., Regions I-X on the Regulatory Status 
    of Printed Circuit Boards.
    ---------------------------------------------------------------------------
    
        EPA has classified baghouse dust from precious metal recovery 
    furnaces as a sludge. 3 As with the by-product 
    classification for sweeps, baghouse dust is not a solid and hazardous 
    waste when it would be considered hazardous only for exhibiting a 
    characteristic such as toxicity. However, if the source material to the 
    furnace contained a listed hazardous waste, then the baghouse dust 
    would be considered a solid and hazardous waste due to its 
    classification as a listed sludge being reclaimed. Also as with the 
    sweeps, even if the baghouse dust is a listed sludge, it may still be 
    conditionally exempt from RCRA regulation under 40 CFR Part 266 Subpart 
    F if it contains economically recoverable levels of precious metals.

        \3\ Ibid.
    ---------------------------------------------------------------------------
    
        Finally, EPA currently classifies solder dross as a characteristic 
    by-product when reclaimed. As such, this material is already excluded 
    from the definition of solid waste and not regulated under the RCRA 
    regulations. Therefore, including solder dross in today's final rule 
    would be duplicative.
    
    IX. 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 treatment standards for wood preserving wastes are 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
    
        In the August 22, 1995, LDR Phase IV proposed rule, EPA proposed a 
    set of streamlined authorization procedures that would apply to new 
    rules that were minor or routine in nature. This procedure was 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). In the HWIR-Media proposed rule, EPA proposed 
    another set of abbreviated authorization procedures for more 
    significant rulemakings, called Category 2 (see 61 FR 18780, April 29, 
    1996). In this latter proposal, EPA designated the procedures outlined 
    in the Phase IV proposal as Category 1. In that proposal, EPA also 
    presented an expanded discussion on the need for and the intent of the 
    streamlined procedures. EPA also proposed a set of modified Category 1 
    procedures for the authorization of a proposed rule for mineral 
    processing wastes on January 25, 1996 (see 62 FR 2338).
        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 in today's notice. EPA 
    believes that public comments from the August 22, 1995, and January 25, 
    1996, proposals and comments submitted for the recent HWIR-contaminated 
    media proposal should all 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 address all significant public comments for 
    all three notices and finalize streamlined authorization procedures 
    when the HWIR-Media rule is promulgated.
    
    C. Effect on State Authorization
    
        Because today's Phase IV 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 listed wood preserving 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. These new treatment standards also 
    result in a more stringent Federal program than before. Therefore 
    States are required to adopt them in accordance with the requirements 
    below.
        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
    
    [[Page 26015]]
    
    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 section 271.21(e). This deadline can be 
    extended in certain cases (see section 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 may, 
    but 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.
    
    D. Less Stringent Requirements
    
        Section 3009 of RCRA allows States to impose standards that are 
    more stringent than the Federal program (see 40 CFR 270.1(i)). Thus, 
    for those Federal changes that are less stringent or reduce the scope 
    of the Federal program, States are not required to modify their 
    programs. EPA views the parts of today's rule other than the new 
    treatment standards for newly listed wood preserving wastes to be less 
    stringent. However, since these other parts of today's final rule make 
    significant improvements to the LDR program, EPA strongly encourages 
    States to adopt and become authorized for them.
    
    X. 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 final rule to determine 
    if it is a significant regulation as defined by the Executive Order. 
    The analysis considered compliance cost and economic impacts for newly 
    listed and identified wastes affected by this rule. This rule covers 
    three wood preserving wastes (F032, F034, and F035). EPA has determined 
    that this rule is significant according to the definition in Executive 
    Order 12866. Accordingly, this rule has been reviewed by the Office of 
    Management and Budget.
        Detailed discussions of the methodology used for estimating the 
    costs, economic impacts and the benefits attributable to today's final 
    rule, followed by a presentation of the cost, economic impact and 
    benefit results may be found in the background document, ``Regulatory 
    Impact Analysis of the Final Phase IV Land Disposal Restrictions 
    Rule,'' which was placed in the docket for today's final rule.
    1. Methodology Section
        The Agency estimated the volumes of waste affected by today's rule 
    to determine the national level incremental costs (for both the 
    baseline and post-regulatory scenarios), economic impacts (defined as 
    the difference between the industrial activity under post-regulatory 
    conditions and the industrial activity in the absence of regulation), 
    and benefits (including estimation of pollutant loadings reductions, 
    estimation of reductions in exceedences of health-based levels, and 
    qualitative description of the potential benefits.) The procedure for 
    estimating the volumes of newly listed wood preserving wastes affected 
    by today's final rule is detailed in the background document 
    ``Regulatory Impact Analysis of the Final Phase IV Land Disposal 
    Restrictions Rule for Wood Preserving Wastes, F032, F034 and F035,'' 
    which was placed in the docket for today's final rule.
    2. Volume Results
        The Agency has estimated that 469 active facilities generate an 
    estimated range of 3,860 tons to 18,808 tons annually of newly listed 
    wood preserving wastes including F032, F034, and F035 nonwastewaters. 
    The Agency has estimated that active 469 facilities generate an 
    estimated range of 3,860 tons to 18,808 tons annually of newly listed 
    wood preserving wastes including F032, F034, and F035 nonwastewaters. 
    In addition the Agency has estimated that there are approximately 1000 
    inactive or abandoned wood preserving sites that have contaminated soil 
    and debris that may require some type of remediation. One Agency 
    estimate for the total volume of wood preserving contaminated soil and 
    debris requiring either in-situ or ex-situ treatment is 37 million tons 
    based on an extrapolation of the average quantity of excavated soils 
    from wood preserving Superfund sites. For purposes of the capacity 
    analysis in today's rule, the Agency is using an alternate estimate of 
    over 100,000 tons as the basis of setting the national capacity 
    variance for wood preserving soil and debris.
    3. Cost Results
        EPA estimated the incremental treatment cost attributable to Phase 
    IV LDRs to total between $3.1 million and $17.7 million per year for 
    generators of newly listed wood preserving wastes. In addition, EPA has 
    estimated that administrative requirements for reporting and record 
    keeping from today's rule will result in a cost of $0.2 million per 
    year for owners and
    
    [[Page 26016]]
    
    operators of inactive and abandoned wood preserving sites. This 
    estimate is based on the costs of thermal destruction and stabilization 
    of F032 and F034 non-wastewaters; the costs of stabilization of F035 
    non-wastewaters; and the incremental cost of disposing of the residuals 
    from the treatment of the 3,860-18,808 tons of waste.
        Today's final rule provides a two year capacity variance during 
    which cleanups of these sites may continue without being affected by 
    the Land Disposal Restriction treatment standards promulgated in 
    today's rule. This provision will reduce the costs of managing media 
    contaminated by these listed wastes to the extent that facility 
    operators and site managers take advantage of it. Also, many sites are 
    using in-situ remedies where no soil is excavated at the site. This 
    type of remediation does not trigger any of the requirements 
    promulgated in today's rule.
        Prospectively, future rulemakings such as the Hazardous Waste 
    Indentification Final Rule for contaminated media may result in 
    quantities of contaminated soil being removed from RCRA jurisdiction or 
    subject to less rigorous cleanup levels than the current universal 
    treatment standards. Inactive and abandoned wood preserving sites may 
    avail themselves of exemptions from today's promulgated treatment 
    standards such as a no-migration petition (40 CFR Part 268.6) or site 
    specific treatability variances (40 CFR Part 268.44(h)). Further 
    reductions in treatment cost will accrue to the extent that (1) EPA 
    acts to remove media contaminated with these listed wastes from RCRA 
    jurisdiction and (2) facility operators and site managers petition for, 
    and EPA grants, these no-migration petitions and treatability 
    variances. For the foregoing reasons, EPA does not believe that 
    incremental treatment costs will accrue to contaminated media cleanups 
    at inactive or abandoned wood preserving sites. Accordingly, EPA has 
    not estimated incremental treatment costs that would result from the 
    selection of a more expensive remedy in order to avoid triggering LDR 
    treatment requirements. Although EPA believes that this scenario is 
    unlikely, such costs are possible.
        With respect to media contaminated with listed wood preserving 
    wastes, EPA's estimate of the costs of today's final rule includes only 
    the administrative costs of applying for treatability variances which 
    the Agency has the discretion to grant subsequent to this action. EPA 
    estimates that there are 35 million tons of such contaminated media 
    that incur administrative costs for treatability variances, waste 
    analysis plans, and other RCRA activities. The Agency will estimate the 
    volume and cost of remediating contaminated media as affected by the 
    HWIR Contaminated Media final rule. This will include the evaluation of 
    all soils and sludges that would otherwise have been treated in-situ 
    whose management and treatment costs could change, either because of 
    provisions of the HWIR Contaminated Media final rule; changes in 
    relative prices for alternative treatment technologies; or increases in 
    market prices of treatment resulting from such shifts in demand. EPA 
    will use the same baseline for estimating these costs that the Agency 
    uses to estimate cost savings.
    4. Economic Impact Results
        The Agency has estimated the economic impacts of today's final rule 
    to be small. EPA conducted an initial screening analysis of the impacts 
    of the Phase IV LDR rule on small wood preserving facilities. Results 
    of the initial screening analysis indicate that the cost of compliance 
    for the majority of active wood preserving facilities that use 
    inorganic wood preservatives and generate F035 wastes is less than one 
    percent of total their estimated revenues. In contrast, active wood 
    preserving facilities that use creosote and pentachlorophenol as a 
    preservatives and generated F032 and F034 wastes have been estimated to 
    incur upper bound compliance costs that may exceed one percent of this 
    subsector's revenues.
        Some active wood preserving facilities that use creosote and 
    pentachlorophenol as preservatives may incur upper bound compliance 
    costs that will exceed one percent of their estimated revenues. EPA 
    believes, however, that in looking at the affected universe of active 
    wood preserving facilities, today's final rule will not constitute a 
    significant impact to a substantial number of them. First, only 18 or 
    roughly 4 percent of over 469 wood preserving facilities are expected 
    to incur compliance costs that exceed 2 percent of their revenues or 
    more than 25 percent of their long run profits. Of the remaining 49 
    facilities or 10 percent with upper bound estimated compliance costs 
    exceeding 1 percent of their revenue, none are expected to incur 
    compliance costs exceeding 2 percent of firm revenues or 25 percent of 
    long term profits. Second, industry information suggests that there is 
    a trend within the wood preserving industry away from using 
    pentachlorophenol as a preservative. Product substitution to other 
    nontoxic or toxic preservatives resulting in less expensive treatment 
    of wastes may result in lower costs to these wood preserving 
    facilities. Finally, data collected to estimate the upper bound 
    quantity of F032 generated at these facilities included values for 
    mixed F032/F034/F035 wastes (meaning that the generator reported 
    combined volumes for F032 and other wood preserving wastes) such that 
    the total volume of F032 is probably much lower than the data suggests.
        For inactive and abandoned wood preserving sites that require 
    remediation, EPA believes that there should not be a significant 
    economic impact resulting from today's rule. Of the estimated 1000 
    sites, based on the frequency of wood preserving Superfund cleanups, 
    EPA projects that over 200 inactive and abandoned sites will use in-
    situ remedies and thus not incur any costs under today's rule. In 
    addition, EPA projects that the remaining 800 sites will incur only 
    administrative costs associated with recordkeeping and reporting 
    requirements that average $240 in annualized cost per site. Given that 
    the reported average cost of cleaning up wood preserving Superfund 
    sites is $9.3 million,4 EPA believes that these 
    administrative costs should not significantly affect remedial 
    activities at inactive and abandoned wood preserving sites.

    5. Benefit Estimate Results
        EPA has not performed analysis sufficient to estimate risks to 
    actual individuals or populations exposed to these listed wastes under 
    conditions of Subtitle C management without LDRs. However, EPA has 
    completed a qualitative benefits analysis of the types of benefits that 
    may result from today's rule. This analysis is described in greater 
    detail in the regulatory impact analysis for newly identified listed 
    wood preserving hazardous waste placed in today's docket. Benefits for 
    this final rule as measured by individual or population risk reduction 
    require substantially more information than the Agency has available 
    now. Further, site specific information on waste characterization, 
    hydrogeological parameters, meteorological conditions and demographic 
    patterns would be needed for a representative number of facilities 
    before national estimates of
    
    [[Page 26017]]
    
    population risk could be calculated. The Agency does not have 
    sufficient information to complete a quantitative individual or 
    population risk estimate.
        While waste management rules to protect ground water have been 
    promulgated in the past to control otherwise unacceptable individual 
    risks, it is unusual to predict high `population risks' unless there is 
    an unusually large water supply well impacted by the facility, simply 
    because ground water contamination generally moves slowly and locally. 
    It has been the agency's experience that regulations with land disposal 
    restrictions have been found to produce relatively small, quantifiable 
    population risk reductions to individuals exposed to contaminated 
    groundwater via private wells. For example, in the analysis of Land 
    Disposal Restrictions Phase II (40 CFR Parts 148, et al.) for organic 
    toxicity wastes, some of the individual risk were in the range of 
    10-4, the population risk reductions were found to be only 
    about 0.22 cases of cancer per year.
        If population densities and prevalence of private ground water 
    wells around wood preserving facilities are similar to other waste 
    management facilities, it is the Agency's expectation that land 
    disposal restrictions for hazardous wood preserving wastes would also 
    achieve relatively small, quantifiable population risk reductions. For 
    these reasons and the data limitations cited above, the Agency has not 
    attempted to address the quantification of population risk reduction 
    for this final rule.
        Nevertheless, the Agency has concluded that LDR rules like today's 
    rule may produce benefits in the area of ecological risk reduction and 
    reduced natural resource damage. EPA has not developed a quantitative 
    assessment of these benefits categories because of budgetary and data 
    limitations.
    
    B. 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).
        In assessing the regulatory approach for dealing with small 
    entities in today's proposed rule, the Agency had to consider that 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 this statutory constraint, 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. For the reasons stated above 
    in the economic impact discussion of section X.A, I hereby certify that 
    today's final rule will not have a significant impact on a substantial 
    number of small entities in the wood preserving sector.
    
    C. Unfunded Mandates Reform Act
    
        Title II of the Unfunded Mandates Reform Act of 1995 (UMBRA), 
    Public Law 104-4, establishes requirements for Federal agencies to 
    assess the effects of their regulatory actions on State, Tribal, and 
    local governments and the private sector. Under section 202 of the 
    UMRA, EPA generally must prepare a written statement, including a cost-
    benefit analysis, for proposed and final rules with ``Federal 
    mandates'' that may result in expenditures to State, local, and Tribal 
    governments, in the aggregate, or to the private sector, of $100 
    million or more in any one year. When a written statement is needed for 
    an EPA rule, section 205 of the UMRA generally requires EPA to identify 
    and consider a reasonable number of regulatory alternatives and adopt 
    the least costly, most cost-effective, or least burdensome alternative 
    that achieves the objectives of the rule. The provisions of section 205 
    do not apply when they are inconsistent with applicable law. Moreover, 
    section 205 allows EPA to adopt an alternative other than the least 
    costly, most cost-effective or least burdensome alternative if the 
    Administrator publishes with the final rule an explanation why that 
    alternative was not adopted. Before EPA establishes any regulatory 
    requirements that may significantly or uniquely affect small 
    governments, including Tribal governments, it must have developed under 
    section 203 of the UMRA a small government agency plan. The plan must 
    provide for notifying potentially affected small governments, giving 
    them meaningful and timely input in the development of EPA regulatory 
    proposals with significant Federal intergovernmental mandates, and 
    informing, educating, and advising them on compliance with the 
    regulatory requirements.
        EPA has determined that this rule does not contain a Federal 
    mandate that may result in expenditures of $100 million or more for 
    State, local, and Tribal governments, in the aggregate, or the private 
    sector in any one year. EPA has estimated that the total potential cost 
    to State, local, and Tribal governments would not exceed approximately 
    $200,000 per year over ten years. Thus, today's rule is not subject to 
    the requirements of sections 202 and 205 of the UMRA.
    
    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. An 
    Information Collection Request (ICR) document has been prepared by EPA: 
    OSWER ICR No. 1442.14 would amend the existing ICR approved under OMB 
    Control No. 2050-0085. This ICR has not been approved by OMB and the 
    information collection requirements, although they are less stringent 
    than those previously required by the EPA, are not enforceable until 
    OMB approves the ICR. EPA will publish a document in the Federal 
    Register when OMB approves the information collection requirements 
    showing the valid OMB control number. Until then, persons are not 
    required to respond to collections of information in this ICR.
        Copies of this ICR 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 number in any request.
        The annual public reporting and recordkeeping burden for this 
    collection of information is estimated to be reduced by 8 hours per 
    response. 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 
    comply with any previously applicable instructions and requirements, 
    train personnel to be able to respond to a
    
    [[Page 26018]]
    
    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. The OMB control numbers for EPA's 
    regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15.
        Send comments on the Agency's burden reduction, 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.

    XI. Environmental Justice
    
    A. Applicability of Executive Order 12898
    
        EPA is committed to address environmental justice concerns and is 
    assuming a leadership role in environmental justice initiatives to 
    enhance environmental quality for all residents of the United States. 
    The Agencies goals are to ensure that no segment of the population, 
    regardless of race, color, national origin, or income bears 
    disproportionately high and adverse human health and environmental 
    effects as a result of EPA's policies, programs, and activities, and 
    all people live in clean and sustainable communities.
    
    B. Potential Effects
    
        Today's rule is intended to reduce risks of disposing hazardous 
    wastes, and to benefit all populations. This rule is not expected to 
    cause any disproportionate impacts to minority or low income 
    communities versus affluent or non-minority communities.
    
    XII. Submission to Congress and 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).

    Sec. 261.1  Purpose and scope.
    
    * * * * *
        (c) * * *
        (9) ``Excluded scrap metal'' is processed scrap metal, unprocessed 
    home scrap metal, and unprocessed prompt scrap metal.
        (10) ``Processed scrap metal'' is scrap metal which has been 
    manually or physically altered to either separate it into distinct 
    materials to enhance economic value or to improve the handling of 
    materials. Processed scrap metal includes, but is not limited to scrap 
    metal which has been baled, shredded, sheared, chopped, crushed, 
    flattened, cut, melted, or separated by metal type (i.e., sorted), and, 
    fines, drosses and related materials which have been agglomerated. 
    (Note: shredded circuit boards being sent for recycling are not 
    considered processed scrap metal. They are covered under the exclusion 
    from the definition of solid waste for shredded circuit boards being 
    recycled (Sec. 261.4(a)(13)).
        (11) ``Home scrap metal'' is scrap metal as generated by steel 
    mills, foundries, and refineries such as turnings, cuttings, punchings, 
    and borings.
        (12) ``Prompt scrap metal'' is scrap metal as generated by the 
    metal working/fabrication industries and includes such scrap metal as 
    turnings, cuttings, punchings, and borings. Prompt scrap is also known 
    as industrial or new scrap metal.
        5. Section 261.2(c) is amended by revising table 1 to read as 
    follows:

    revising paragraph (a); by removing paragraph (b)(2) and redesignating 
    paragraphs (b)(3) through (b)(7) as (b)(2) through (b)(6) respectively; 
    and by revising the introductory text of paragraph (b), and revising 
    paragraphs (b)(1), newly designated paragraphs (b)(2) through (b)(4), 
    (c)(1), and (c)(2) to read as follows:
    
    
    Sec. 268.7  Testing, tracking, and recordkeeping requirements for 
    generators, treaters, and disposal facilities.
    
        (a) Requirements for generators: (1) Determine if the waste has to 
    be treated before being land disposed, as follows: A generator of a 
    hazardous waste must determine if the waste has to be treated before it 
    can be land disposed. This is done by determining if the hazardous 
    waste meets the treatment standards in Sec. 268.40 or Sec. 268.45. This 
    determination can be made in either of two ways: testing the waste or 
    using knowledge of the waste. If the generator tests the waste, testing 
    would normally determine the total concentration of hazardous 
    constituents, or the concentration of hazardous constituents in an 
    extract of the waste obtained using test method 1311 in ``Test Methods 
    for Evaluating Solid Waste, Physical/Chemical Methods,'' EPA 
    Publication SW-846, as referenced in Sec. 260.11 of this chapter, 
    depending on whether the treatment standard for the waste is expressed 
    as a total concentration or concentration of hazardous constituent in 
    the waste's extract. In addition, some hazardous wastes must be treated 
    by particular treatment methods before they can be land disposed. These 
    treatment standards are also found in Sec. 268.40, and are described in 
    detail in Sec. 268.42, Table 1. These wastes do not need to be tested 
    (however, if they are
    
    [[Page 26020]]
    
    in a waste mixture, other wastes with concentration level treatment 
    standards would have to be tested). If a generator determines they are 
    managing a waste that displays a hazardous characteristic of 
    ignitability, corrosivity, reactivity, or toxicity, they must comply 
    with the special requirements of Sec. 268.9 of this part in addition to 
    any applicable requirements in this section.
        (2) If the waste does not meet the treatment standard: With the 
    initial shipment of waste to each treatment or storage facility, the 
    generator must send a one-time written notice to each treatment or 
    storage facility receiving the waste, and place a copy in the file. The 
    notice must include the information in column ``268.7(a)(2)'' of the 
    Generator Paperwork Requirements Table in Sec. 268.7(a)(4). No further 
    notification is necessary until such time that the waste or facility 
    change, in which case a new notification must be sent and a copy placed 
    in the generator's file.
        (3) If the waste meets the treatment standard at the original point 
    of generation:
        (i) With the initial shipment of waste to each treatment, storage, 
    or disposal facility, the generator must send a one-time written notice 
    to each treatment, storage, or disposal facility receiving the waste, 
    and place a copy in the file. The notice must include the information 
    indicated in column ``268.7(a)(3)'' of the Generator Paperwork 
    Requirements Table in Sec. 268.7(a)(4) and the following certification 
    statement, signed by an authorized representative:
    
        I certify under penalty of law that I personally have examined 
    and am familiar with the waste through analysis and testing or 
    through knowledge of the waste to support this certification that 
    the waste complies with the treatment standards specified in 40 CFR 
    part 268 subpart D. I believe that the information I submitted is 
    true, accurate, and complete. I am aware that there are significant 
    penalties for submitting a false certification, including the 
    possibility of a fine and imprisonment.
    
        (ii) If the waste changes, the generator must send a new notice and 
    certification to the receiving facility, and place a copy in their 
    files. Generators of hazardous debris excluded from the definition of 
    hazardous waste under Sec. 261.3(f) of this chapter are not subject to 
    these requirements.
        (4) For reporting, tracking and recordkeeping when exceptions allow 
    certain wastes that do not meet the treatment standards to be land 
    disposed: There are certain exemptions from the requirement that 
    hazardous wastes meet treatment standards before they can be land 
    disposed. These include, but are not limited to case-by-case extensions 
    under Sec. 268.5, disposal in a no-migration unit under Sec. 268.6, or 
    a national capacity variance or case-by-case capacity variance under 
    subpart C of this part. If a generator's waste is so exempt, then with 
    the initial shipment of waste, the generator must send a one-time 
    written notice to each land disposal facility receiving the waste. The 
    notice must include the information indicated in column ``268.7(a)(4)'' 
    of the Generator Paperwork Requirements Table below. If the waste 
    changes, the generator must send a new notice to the receiving 
    facility, and place a copy in their files.

        (5) If a generator is managing and treating prohibited waste in 
    tanks, containers, or containment buildings regulated under 40 CFR 
    262.34 to meet applicable LDR treatment standards found at Sec. 268.40, 
    the generator must develop and follow a written waste analysis plan 
    which describes the procedures they will carry out to comply with the 
    treatment standards. (Generators treating hazardous debris under the 
    alternative treatment standards of Table 1, Sec. 268.45, however, are 
    not subject to these waste analysis requirements.) The plan must be 
    kept on site in the generator's records, and the following requirements 
    must be met:
        (i) The waste analysis plan must be based on a detailed chemical 
    and physical analysis of a representative sample of the prohibited 
    waste(s) being treated, and contain all information necessary to treat 
    the waste(s) in accordance with the requirements of this part, 
    including the selected testing frequency.
        (ii) Such plan must be kept in the facility's on-site files and 
    made available to inspectors.
        (iii) Wastes shipped off-site pursuant to this paragraph must 
    comply with the notification requirements of Sec. 268.7(a)(3).
        (6) If a generator determines that the waste is restricted based 
    solely on his knowledge of the waste, all supporting data used to make 
    this determination must be retained on-site in the generator's files. 
    If a generator determines that the waste is restricted based on testing 
    this waste or an extract developed using the test method 1311 in ``Test 
    Methods for Evaluating Solid Waste, Physical/Chemical Methods,'' EPA 
    Publication SW-846, as referenced in Sec. 260.11 of this chapter, and 
    all waste analysis data must be retained on-site in the generator's 
    files.
        (7) If a generator determines that he is managing a restricted 
    waste that is
    
    [[Page 26021]]
    
    excluded from the definition of hazardous or solid waste or exempt from 
    Subtitle C regulation, under 40 CFR 261.2 through 261.6 subsequent to 
    the point of generation (including deactivated characteristic hazardous 
    wastes managed in wastewater treatment systems subject to the Clean 
    Water Act (CWA) as specified at 40 CFR 261.4(a)(2), or are CWA-
    equivalent), he must place a one-time notice stating such generation, 
    subsequent exclusion from the definition of hazardous or solid waste or 
    exemption from RCRA Subtitle C regulation, and the disposition of the 
    waste, in the facility's file.
        (8) Generators must retain on-site a copy of all notices, 
    certifications, waste analysis data, and other documentation produced 
    pursuant to this section for at least three years from the date that 
    the waste that is the subject of such documentation was last sent to 
    on-site or off-site treatment, storage, or disposal. The three year 
    record retention period is automatically extended during the course of 
    any unresolved enforcement action regarding the regulated activity or 
    as requested by the Administrator. The requirements of this paragraph 
    apply to solid wastes even when the hazardous characteristic is removed 
    prior to disposal, or when the waste is excluded from the definition of 
    hazardous or solid waste under 40 CFR 261.2 through 261.6, or exempted 
    from Subtitle C regulation, subsequent to the point of generation.
        (9) If a generator is managing a lab pack containing hazardous 
    wastes and wishes to use the alternative treatment standard for lab 
    packs found at Sec. 268.42(c):
        (i) With the initial shipment of waste to a treatment facility, the 
    generator must submit a notice that provides the information in column 
    ``Sec. 268.7(a)(9)'' in the Generator Paperwork Requirements Table of 
    paragraph (a)(4) of this section, and the following certification. The 
    certification, which must be signed by an authorized representative and 
    must be placed in the generator's files, must say the following:
    
        I certify under penalty of law that I personally have examined 
    and am familiar with the waste and that the lab pack contains only 
    wastes that have not been excluded under appendix IV to 40 CFR part 
    268 and that this lab pack will be sent to a combustion facility in 
    compliance with the alternative treatment standards for lab packs at 
    40 CFR 268.42(c). I am aware that there are significant penalties 
    for submitting a false certification, including the possibility of 
    fine or imprisonment.
    
        (ii) No further notification is necessary until such time that the 
    wastes in the lab pack change, or the receiving facility changes, in 
    which case a new notice and certification must be sent and a copy 
    placed in the generator's file.
        (iii) If the lab pack contains characteristic hazardous wastes 
    (D001-D043), underlying hazardous constituents (as defined in 
    Sec. 268.2(i)) need not be determined.
        (iv) The generator must also comply with the requirements in 
    paragraphs (a)(6) and (a)(7) of this section.
        (10) Small quantity generators with tolling agreements pursuant to 
    40 CFR 262.20(e) must comply with the applicable notification and 
    certification requirements of paragraph (a) of this section for the 
    initial shipment of the waste subject to the agreement. Such generators 
    must retain on-site a copy of the notification and certification, 
    together with the tolling agreement, for at least three years after 
    termination or expiration of the agreement. The three-year record 
    retention period is automatically extended during the course of any 
    unresolved enforcement action regarding the regulated activity or as 
    requested by the Administrator.
        (b) Treatment facilities must test their wastes according to the 
    frequency specified in their waste analysis plans as required by 40 CFR 
    264.13 (for permitted TSDs) or 40 CFR 265.13 (for interim status 
    facilities). Such testing must be performed as provided in paragraphs 
    (b)(1), (b)(2) and (b)(3) of this section.
        (1) For wastes with treatment standards expressed as concentrations 
    in the waste extract (TCLP), the owner or operator of the treatment 
    facility must test an extract of the treatment residues, using test 
    method 1311 (the Toxicity Characteristic Leaching Procedure, described 
    in ``Test Methods for Evaluating Solid Waste, Physical/Chemical 
    Methods,'' EPA Publication SW-846 as incorporated by reference in 
    Sec. 260.11 of this chapter), to assure that the treatment residues 
    extract meet the applicable treatment standards.
        (2) For wastes with treatment standards expressed as concentrations 
    in the waste, the owner or operator of the treatment facility must test 
    the treatment residues (not an extract of such residues) to assure that 
    they meet the applicable treatment standards.
        (3) A one-time notice must be sent with the initial shipment of 
    waste to the land disposal facility. A copy of the notice must be 
    placed in the treatment facility's file.
        (i) No further notification is necessary until such time that the 
    waste or receiving facility change, in which case a new notice must be 
    sent and a copy placed in the treatment facility's file.
        (ii) The one-time notice must include these requirements:

     hazardous constituents (for wastes that are not managed                
     in a Clean Water Act (CWA) or CWA-equivalent facility),                
     unless the waste will be treated and monitored for all                 
     constituents. If all constituents will be treated and                  
     monitored, there is no need to put them all on the LDR                 
     notice..................................................        
    3. The notice must include the applicable wastewater/                   
     nonwastewater category (see Secs.  268.2(d) and (f)) and

     section for exact wording)..............................        
    ------------------------------------------------------------------------
    
        (4) The treatment facility must submit a one-time certification 
    signed by an authorized representative with the initial shipment of 
    waste or treatment residue of a restricted waste to the land disposal 
    facility. The certification must state:
    
        I certify under penalty of law that I have personally examined 
    and am familiar with the treatment technology and operation of the 
    treatment process used to support this certification. Based on my 
    inquiry of those individuals immediately responsible for obtaining 
    this information, I believe that the treatment process has been 
    operated and maintained properly so as to comply with the treatment 
    standards specified in 40 CFR 268.40 without impermissible dilution 
    of the
    
    [[Page 26022]]
    
    prohibited waste. I am aware there are significant penalties for 
    submitting a false certification, including the possibility of fine 
    and imprisonment.
    
        (i) A copy of the certification must be placed in the treatment 
    facility's on-site files. If the waste or treatment residue changes, or 
    the receiving facility changes, a new certification must be sent to the 
    receiving facility, and a copy placed in the file.
        (ii) Debris excluded from the definition of hazardous waste under 
    Sec. 261.3(e) of this chapter (i.e., debris treated by an extraction or 
    destruction technology provided by Table 1, Sec. 268.45, and debris 
    that the Director has determined does not contain hazardous waste), 
    however, is subject to the notification and certification requirements 
    of paragraph (d) of this section rather than the certification 
    requirements of this paragraph.
        (iii) For wastes with organic constituents having treatment 
    standards expressed as concentration levels, if compliance with the 
    treatment standards is based in whole or in part on the analytical 
    detection limit alternative specified in Sec. 268.40(d), the 
    certification, signed by an authorized representative, must state the 
    following:
    
        I certify under penalty of law that I have personally examined 
    and am familiar with the treatment technology and operation of the 
    treatment process used to support this certification. Based on my 
    inquiry of those individuals immediately responsible for obtaining 
    this information, I believe that the nonwastewater organic 
    constituents have been treated by combustion units as specified in 
    268.42, Table 1. I have been unable to detect the nonwastewater 
    organic constituents, despite having used best good-faith efforts to 
    analyze for such constituents. I am aware there are significant 
    penalties for submitting a false certification, including the 
    possibility of fine and imprisonment.

        (1) Have copies of the notice and certifications specified in 
    paragraph (a) or (b) of this section.
        (2) Test the waste, or an extract of the waste or treatment residue 
    developed using test method 1311 (the Toxicity Characteristic Leaching 
    Procedure), described in ``Test Methods for Evaluating Solid Waste, 
    Physical/Chemical Methods,'' EPA Publication SW-846 as incorporated by 
    reference in Sec. 260.11 of this chapter), to assure that the wastes or 
    treatment residues are in compliance with the applicable treatment 
    standards set forth in subpart D of this part. Such testing must be 
    performed according to the frequency specified in the facility's waste 
    analysis plan as required by Sec. 264.13 or Sec. 265.13 of this 
    chapter.

        12. Section 268.9 is amended by revising paragraph (a) and 
    (d)(1)(ii) to read as follows:
    
    
    Sec. 268.9  Special rules regarding wastes that exhibit a 
    characteristic.
    
        (a) The initial generator of a solid waste must determine each EPA 
    Hazardous Waste Number (waste code) applicable to the waste in order to 
    determine the applicable treatment standards under subpart D of this 
    part. For purposes of part 268, the waste will carry the waste code for 
    any applicable listed waste (Part 261, Subpart D). In addition, where 
    the waste exhibits a characteristic, the waste will carry one or more 
    of the characteristic waste codes (Part 261, Subpart C), except when 
    the treatment standard for the listed waste operates in lieu of the 
    treatment standard for the characteristic waste, as specified in 
    paragraph (b) of this section. If the generator determines that their 
    waste displays a hazardous characteristic (and is not D001 
    nonwastewaters treated by CMBST, RORGS, OR POLYM of Sec. 268.42, Table 
    1), the generator must determine the underlying hazardous constituents 
    (as defined at Sec. 268.2(i)) in the characteristic waste.
    * * * * *
        (d) * * *
        (1) * * *
        (ii) A description of the waste as initially generated, including 
    the applicable EPA hazardous waste code(s), treatability group(s), and 
    underlying hazardous constituents (as defined in Sec. 268.2(i)), unless 
    the waste will be treated and monitored for all underlying hazardous 
    constituents. If all underlying hazardous constituents will be treated 
    and monitored, there is no requirement to list any of the underlying 
    hazardous constituents on the notice.

    Subpart C--Prohibitions on Land Disposal
    
        13. Section 268.30 is revised to read as follows:
    
    
    Sec. 268.30  Waste specific prohibitions--wood preserving wastes.
    
        (a) Effective August 11, 1997, the following wastes are prohibited 
    from land disposal: the wastes specified in 40 CFR part 261 as EPA 
    Hazardous Waste numbers F032, F034, and F035.
        (b) Effective May 12, 1999, the following wastes are prohibited 
    from land disposal: soil and debris contaminated with F032, F034, F035; 
    and radioactive wastes mixed with EPA Hazardous waste numbers F032, 
    F034, and F035.
        (c) Between May 12, 1997 and May 12, 1999, soil and debris 
    contaminated with F032, F034, F035; and radioactive waste mixed with 
    F032, F034, and F035 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) of this part.
        (d) The requirements of paragraphs (a) and (b) 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; or
        (4) Persons have been granted an extension to the effective date of 
    a prohibition pursuant to Sec. 268.5, with respect to those wastes 
    covered by the extension.
        (e) 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 Universal Treatment 
    Standard levels of Sec. 268.48 of this part, the waste is prohibited 
    from land disposal, and all requirements of part 268 are applicable, 
    except as otherwise specified.

    \1\ The waste descriptions provided in this table do not replace waste descriptions in 40 CFR part 261. Descriptions of Treatment/Regulatory            
      Subcategories are provided, as needed, to distinguish between applicability of different standards.                                                   
    \2\ CAS means Chemical Abstract Services. When the waste code and/or regulated constituents are described as a combination of a chemical with its salts 
      and/or esters, the CAS number is given for the parent compound only.                                                                                  
    \3\ Concentration standards for wastewaters are expressed in mg/l and are based on analysis of composite samples.                                       
    \4\ All treatment standards expressed as a Technology Code or combination of Technology Codes are explained in detail in Sec.  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 Sec.  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

        17. Section 268.44 is amended by revising both entries in the ``see 
    also'' column of the table in paragraph (o) to read ``Sec. 268.40'' and 
    by revising the introductory language of paragraph (o) and the heading

        18. Appendices I, II, III, and X to part 268 are removed and 
    reserved.
        19. The introductory language of appendix VI to part 268 is revised 
    to read as follows:
    
    Appendix VI to Part 268--Recommended Technologies to Achieve 
    Deactivation of Characteristics in Section 268.42
    
        The treatment standard for many characteristic wastes is stated 
    in the Sec. 268.40 Table of Treatment Standards as ``Deactivation 
    and meet UTS.'' EPA has determined that many technologies, when used 
    alone or in combination, can achieve the deactivation portion of the 
    treatment standard. Characteristic wastes that are not managed in a 
    facility regulated by the Clean Water Act (CWA) or in a CWA-
    equivalent facility, and that also contain underlying hazardous 
    constituents (see Sec. 268.2(i)) must be treated not only by a 
    ``deactivating'' technology to remove the characteristic, but also 
    to achieve the universal treatment standards (UTS) for underlying 
    hazardous constituents. The following appendix presents a partial 
    list of technologies, utilizing the five letter technology codes 
    established in 40 CFR 268.42 Table 1, that may be useful in meeting 
    the treatment standard. Use of these specific technologies is not 
    mandatory and does not preclude direct reuse, recovery, and/or the 
    use of other pretreatment technologies, provided deactivation is 
    achieved and underlying hazardous constituents are treated to 
    achieve the UTS.
