    SUMMARY: The Environmental Protection Agency (EPA or Agency) is 
    amending its hazardous waste regulations for testing and monitoring 
    activities. This amendment adds new and revised methods as Update III 
    to the Third Edition of the EPA-approved test methods manual ``Test 
    Methods for Evaluating Solid Waste, Physical/Chemical Methods,'' EPA 
    Publication SW-846 and deletes several obsolete methods from SW-846 and 
    the RCRA regulations. It also incorporates SW-846, Third Edition, as 
    amended by Updates I (July 1992), II (September 1994) and IIA (August 
    1993 as part of the wood surface protection rule), IIB (January 1995, 
    clarifying the temperature requirement for pH measurements of highly 
    alkaline wastes), and III (December 1996). The intent of this action is 
    to provide state-of-the-art analytical technologies for RCRA-related 
    testing, thus promoting cost effectiveness and flexibility in choosing 
    analytical test methods, as well as clarifying the RCRA Program's

    I. Legal Authority
    
        These regulations are being promulgated under the authority of 
    sections 1006, 2002(a), 3001-3007, 3010, 3013-3018, and 7004 of the 
    Solid Waste Disposal Act, as amended by the Resource Conservation and 
    Recovery
    
    [[Page 32453]]
    
    Act of 1976 (commonly known as RCRA), as amended (42 U.S.C. 6905, 
    6912(a), 6921-6927, 6930, 6934-6939, and 6974).
    
    II. Background Summary and Regulatory Framework
    
        EPA Publication SW-846, ``Test Methods for Evaluating Solid Waste, 
    Physical/Chemical Methods,'' contains the analytical and test methods 
    that EPA has evaluated and found to be among those acceptable for 
    testing under subtitle C of the Resource Conservation and Recovery Act 
    (RCRA), as amended. Use of some of these methods is required by some of 
    the hazardous waste regulations under subtitle C of RCRA. In other 
    situations, SW-846 functions as a guidance document setting forth 
    acceptable, although not required, methods to be implemented by the 
    user, as appropriate, in satisfying RCRA-related sampling and analysis 
    requirements. All of these methods are intended to promote accuracy, 
    sensitivity, specificity, precision, and comparability of analyses and 
    test results.
        SW-846 is a document that changes over time as new information and 
    data are developed. Advances in analytical instrumentation and 
    techniques are continually reviewed by the Agency's Office of Solid 
    Waste (OSW) and periodically incorporated into SW-846 to support 
    changes in the regulatory program and to improve method performance and 
    cost effectiveness. Update III represents such an incorporation.
        As a result of this final rule, SW-846 is being amended further to 
    include the new and revised methods contained in Update III, and to 
    delete those methods deemed obsolete.
    
    III. Overview of July 25, 1995 NPRM and Summary of Responses to Public 
    Comments
    
    A. Overview of Proposal
    
        On July 25, 1995 (60 FR 37974), the Agency proposed to amend its 
    hazardous waste testing and monitoring regulations under subtitle C of 
    RCRA by: (1) Adding revised methods and chapters and new methods as 
    Update III to SW-846 and incorporating the Third Edition of SW-846 as 
    amended by Updates I, II, IIA, IIB, and III, into 40 CFR 260.11(a) for 
    use in complying with the requirements of subtitle C of RCRA, (2) 
    deleting certain methods from SW-846 which are deemed obsolete, and (3) 
    deleting certain references to Method 8240, Volatile Organics by Gas 
    Chromatography/Mass Spectrometry (GC/MS), found in 40 CFR 264.1034, 
    264.1063, 265.1034, and 265.1063.
        The Agency solicited comments on each of these proposed changes. On 
    December 22, 1995 (60 FR 49239), the Agency extended the comment period 
    to allow resolution of problems involving the shipping of Proposed 
    Update III to many SW-846 subscribers. The extension allowed the 
    subscribers an opportunity to review the Proposed Update III package 
    and supply comments to the Agency.
        Items B through D of this section summarize the major comments 
    received and the actions taken by the Agency in response to those 
    comments.1
    ---------------------------------------------------------------------------
    
        \1\ All comments received are in the docket for the proposed 
    rule (Docket No. F-95-WT3P-FFFFF). Summaries of the comments 
    together with the Agency's responses are in ``Response to Public 
    Comments Background Document, Promulgation of the Third Update to 
    SW-846, Third Edition'' which is in the docket for this final rule 
    (Docket No. F-97-WT3F-FFFFF).
    ---------------------------------------------------------------------------
    
    B. Responses to Comments Regarding the Addition of Update III Methods 
    and Chapters to SW-846
    
        The Agency proposed, as part of Update III to SW-846, to revise 37 
    methods and 6 chapters already contained in the Third Edition of SW-
    846, as amended by Updates I, II, IIA, and IIB, incorporated by 
    reference in 40 CR 260.11. The revisions were proposed to improve the 
    methods and provide additional performance information for these 
    methods. As part of Update III, the Agency also proposed to add 61 new 
    methods to SW-846.
        The Agency received very few negative comments on the proposal to 
    add the new methods and revised methods and chapters of Update III to 
    SW-846. The comments received by the Agency on the addition of new 
    methods and the revision of existing methods and chapters were minor 
    editorial changes. Details on these comments and the Agency's responses 
    may be found in the background document to this rulemaking. The Agency 
    has incorporated several of the suggested changes into the Update III 
    package, as described in the background document.
    
    C. Deletion of Obsolete Methods
    
        The Agency proposed, as part of Update III to SW-846, to delete 
    sixteen obsolete methods from the Third Edition of SW-846, for the 
    reasons delineated in the sections to follow. Table 1 (Method Deletion/
    Replacement Table) lists the methods being deleted and identifies the 
    appropriate replacement methods currently found in SW-846, Third 
    Edition, as amended by Updates I, II, IIA, IIB, and III. The 
    replacement methods are approved for analyses previously conducted by 
    the deleted methods. Regarding the deletion of packed-column methods 
    from SW-846, the Agency notes that packed columns can still be used in 
    the replacement capillary column methods for required purposes, 
    provided that method performance is appropriate for the intended 
    application.

    \1\ The Agency notes that packed columns can still be used in the replacement capillary column methods for      
      required purposes, provided that method performance is appropriate for the intended application. The analysts 
      should also see the Preface and Overview and Chapter Two of SW-846, as well as Method 8000 before beginning   
      any GC analysis (Note: A more detailed discussion on this issue can be found in Section III. C.1 of the       
      preamble).                                                                                                    
    
        Note: A suffix of ``A'' in the method number indicates revision 
    one (the method has been revised once). A suffix of ``B'' in the 
    method number indicates revision two (the method has been revised 
    twice). A suffix of ``C'' in the method number indicates revision 
    three (the method has been revised three times).
    1. Deletion of Packed Column Gas Chromatographic Methods
        Fourteen packed column gas chromatographic (GC) methods were 
    proposed for deletion from SW-846 because they have been superseded by 
    capillary column methods or other method techniques that provide better 
    resolution, selectivity and sensitivity. Most of the commenters did not 
    comment on the proposal to remove the packed column methods from SW-
    846. Of those that did, four commenters were in favor of the removal of 
    the packed column methods, while thirteen opposed the action. In 
    general, both sets of commenters agreed with the Agency that most 
    laboratories use capillary columns, and that capillary columns are a 
    better technology and generate more reliable data than the packed 
    columns. However, all of those opposing the action preferred that the 
    Agency retain the packed column methods as approved for RCRA-related 
    testing and considered their deletion from SW-846 to be either 
    arbitrary or unnecessary. These commenters noted that the capillary 
    columns can be and are used in the packed column methods. The 
    commenters stated that, since SW-846 is a guidance document, the 
    regulated community should have the option of using the packed column 
    methods as long as the generated data are adequate for regulatory 
    purposes. Some commenters in particular desired this option regarding 
    the use of Method 8080, ``Organochlorine Pesticides and Polychlorinated 
    Biphenyls by Gas Chromatography''.
        First, the Agency disagrees with comments that removal of the 
    packed column methods is arbitrary or unnecessary. It is the Agency's 
    responsibility to maintain SW-846 as a manual of standardized methods 
    which EPA believes will provide adequate data for compliance 
    determinations and other RCRA-related analyses. As noted in the 
    proposal (and also observed by the commenters), capillary columns have 
    an inherently greater ability to separate analytes than packed columns. 
    No commenters refuted this finding. In addition, a survey performed in 
    1991 found that few analysts actually use packed columns in their 
    laboratories anymore (Environmental Science and Technology, 26, 1285-
    1287, 1992).
        The packed column GC methods of SW-846 were also proposed for 
    deletion to be consistent with other Agency program offices, e.g., the 
    Office of Water, which has withdrawn packed column methods from its 
    list of approved drinking water methods (see 59 FR 62456, December 5, 
    1994). The Agency is also considering a similar action regarding the 
    methods approved for wastewater analyses. Cross-program consistency 
    regarding the use and approval of packed column methods is important 
    and cost-effective for both the Agency and the regulated community.
        In addition, as shown by Table 1, the Agency is not proposing to 
    delete a packed column method unless at least one other method which 
    uses a commercially available and adequate technology is in SW-846 to 
    replace it.
        Regarding the continued use of any of the packed column methods by 
    the regulated community, the Agency notes that packed columns can still 
    be used in the replacement capillary column methods for required 
    purposes, provided that method performance is
    
    [[Page 32455]]
    
    appropriate for the intended application. The performance data included 
    in SW-846 methods are not intended to be used as absolute QC acceptance 
    criteria for method performance. The data are intended as guidance 
    providing typical method performance in typical matrices, to assist the 
    analyst in the selection of an appropriate method for the intended 
    application. It is the analyst's responsibility to establish the 
    analytical operating parameters and acceptance criteria that are 
    appropriate for that intended application. In addition, the public may 
    continue to use packed column methods, including Method 8080, for 
    applications for which the methods are appropriate.
        Some commenters opposed the deletion of the packed column methods 
    because many of the methods are included in formally approved documents 
    such as permits, EPA-approved Quality Assurance Project Plans, and 
    Consent Decrees. This should not be a cause for concern. Permits and 
    other plans formally approved by regulatory authorities that specify 
    the use of packed column methods for required analyses continue in 
    effect unless they are changed, for example, by amending a consent 
    decree or modifying a permit. In addition, when the permits, etc., are 
    revised, the performance data contained in the packed column methods 
    are not intended to be used as absolute QC acceptance criteria. As with 
    any other methods in SW-846, they are typical performance data expected 
    for typical matrices. The replacement capillary column methods provide 
    superior performance with regard to sensitivity, chromatographic 
    separation, etc., and therefore, the Agency does not believe that 
    amending a permit will be a problem or expense because equivalent 
    methods are already included in SW-846 to meet the analytical 
    requirements stated in permits. Further, the Agency believes that 
    laboratories have been using capillary column methods for these RCRA 
    applications.
        The removal of the packed column methods is a direct example of the 
    Agency's interpretation of PBMS. Capillary column methods represent 
    state-of-the-art in Gas Chromatography technology. Under the PBMS 
    approach, the Agency requires that the generator/analyst be able to 
    demonstrate the ability to meet the Data Quality Objectives (DQOs) for 
    any particular application. For those isolated instances for which the 
    analyst wishes to use a packed column method and can demonstrate the 
    ability to meet project specific DQOs for a particular RCRA 
    application, packed column methods may continue to be used. It is the 
    Agency's policy under the Performance-Based Measurement System (PBMS), 
    that the analytical performance criteria established in the RCRA permit 
    be achieved. The Environmental Monitoring Management Council (EMMC) 
    defines PBMS as ``a set of processes wherein the data quality needs, 
    mandates or limitations of a program or project are specified, and 
    serve as criteria for selecting appropriate methods to meet those needs 
    in a cost-effective manner.'' Under such a system, EPA would specify 
    performance criteria and data producers that would show that their 
    proposed methods meet these specific performance standards. Data 
    producers would be required to document method performance and certify 
    the use of appropriate quality assurance and quality control 
    procedures. The system would apply to those physical, chemical, and 
    biological methods used both in laboratories and in the field. PBMS is 
    a system for specifying monitoring requirements that imposes legal 
    accountability for the achievement of specific data or measurement 
    quality objectives, without prescribing the particular procedures, 
    techniques, or instrumentation that is to be used for achieving such 
    objectives. These performance criteria are defined by the permit, not 
    by a specified method number.
    2. Deletion of Methods 9200 and 9252A
        The Agency also proposed to delete Method 9200 (the brucine-
    sulfanilamide method for nitrate determination), because it generated 
    unreliable results, and Method 9252A (``Chloride, Titrimetric, Mercuric 
    Nitrate), because it generates a mercury-containing RCRA hazardous 
    waste. The Agency did not receive any comments regarding the deletion 
    of these two methods. Therefore, Methods 9200 and 9252 have been 
    deleted and are no longer part of the Third Edition of SW-846 as 
    revised by Final Update III.
    3. Replacing References to Method 8240 With References to Method 8260 
    in Secs. 264.1034(d)(1)(iii) and (f), 264.1063(d)(2), 
    265.1034(d)(1)(iii) and (f), and 265.1063(d)(2)
        The Agency proposed to delete all references to Method 8240 
    (Volatile Organic Compounds by Gas Chromatography/Mass Spectrometry) of 
    SW-846 found in Secs. 264.1034(d)(1)(iii) and (f), 264.1063(d)(2), 
    265.1034(d)(1)(iii) and (f), and 265.1063(d)(2). The Agency did not 
    propose to replace the references to Method 8240 with references to 
    Method 8260 of SW-846, the capillary column replacement method for 
    Method 8240. There were no significant comments objecting to the 
    removal of references to Method 8240 in those sections. However, there 
    was comment that the compound-specific methodology should not be 
    discontinued, leaving only a method that measures total organic 
    concentration. Rather, the preferred capillary column technology should 
    be used in place of the former packed column technology in the analysis 
    of volatile organic compounds by Gas Chromatography/Mass Spectrometry; 
    i.e., Method 8240 should be replaced by Method 8260 in the subject 
    regulations. The Agency agrees with this comment and therefore has 
    replaced references to Method 8240 with references to Method 8260 in 40 
    CFR 264.1034(d)(1)(iii) and (f), 264.1063(d)(2), 265.1034(d)(1)(iii), 
    and 265.1063(d)(2) and (f) of the RCRA regulations. As stated in method 
    8000B, ``Determinative Chromatographic Separations'', the method which 
    provides the Agency's guidance on analytical chromatography, other 
    columns may be substituted in SW-846 methods to improve performance 
    provided that (1) the requirements of Secs. 8.3 (Instrument QC 
    Requirements) and 8.4 (Initial Demonstration of proficiency) of Method 
    8000B are satisfied, and (2) Target analytes are sufficiently resolved 
    from one another, and from co-extracted interferences.
    
        (Note: A method reference found within the RCRA regulations 
    refers to the latest promulgated revision of the method, even though 
    the method number does not include the appropriate letter suffix. 
    For example, in the regulatory sections discussed above, the 
    referenced Method 8260 refers to the last promulgated version of 
    that method, which is Method 8260B of Update III to SW-846.)
    
    IV. Additional Editorial Changes
    
        The Agency is taking this opportunity to make several additional 
    editorial changes resulting from the promulgation of Update III to SW-
    846, Third Edition. These changes include:
    
    --Revising Methods 9010A and 9030A to create new modular format Methods 
    9010B, 9030B, 9014, and 9034, and Editorial Changes to Chapter Seven.
    --Removing section 3.0, ``Sampling and Analytical Methods'', from 
    appendix IX to 40 CFR part 266 because all of the methods can now be 
    found in SW-846.
    --Revising footnote 5 of appendix IX to 40 CFR part 264 to address the 
    status of packed column methods in SW-846.
    --Revising the Disclaimer and Chapter Two of SW-846 to include 
    clarifying
    
    [[Page 32456]]
    
    editorial changes regarding flexibility allowed during the use of SW-
    846 methods.
    
        Since these are technical changes that do not affect the 
    implementation of the regulations, the Agency is simply providing 
    notice of the changes without opportunity for public 
    comment.2 These changes are discussed in detail below.

    inclusive Methods 9010A (Total and Amenable Cyanide) and 9030A (Acid-
    Soluble and Acid-Insoluble Sulfides) of SW-846. The modular versions 
    were created by dividing the preparative and determinative steps of 
    Methods 9010A and 9030A into four separate methodologies. Specifically, 
    revised Method 9010B contains the preparative distillation steps of 
    Method 9010A, and revised Method 9030B contains the preparative 
    distillation steps of Method 9030A. New Method 9014 contains the 
    determinative steps of Method 9010A, and new method 9034 contains the 
    determinative steps of Method 9030A. This modular approach is common to 
    SW-846, and increases flexibility by allowing the selection of 
    preparative and determinative steps that are appropriate to the sample 
    matrix and data end use. (Inclusive methods are desirable, when 
    practicable, i.e., for a specific application in a specific medium or 
    matrix. However, modular methods are more appropriate and practicable 
    when dealing with analyses involving multiple media, as is the case 
    with these two methods.) The text and technical content of Methods 
    9010A and 9030A were not changed when the methods were divided into 
    Methods 9010B, 9014, 9030B, and 9034.
        As a result of dividing Methods 9010 and 9030 into two new methods, 
    the Agency is also correcting those method references in Chapter Seven, 
    steps 2.1, 7.6, and 8.1 of section 7.3.3.2 (Test Method to Determine 
    Hydrogen Cyanide Released from Wastes) and steps 2.1, 7.6, 7.7 and 9.1 
    of section 7.3.4.2 (Test Method to Determine Hydrogen Sulfide Released 
    from Wastes). Specifically, certain incorrect references to ``Method 
    9010'' and ``Method 9030'' have been replaced with correct references 
    to ``Method 9014'' and ``Method 9034''.
    
    B. Revision of Section 3.0 (Sampling and Analytical Methods) of 
    Appendix IX to 40 CFR Part 266
    
        The Agency has revised appendix IX of 40 CFR part 266 whereby the 
    text of section 3.0, Sampling and Analytical Methods, has been removed, 
    and a note has been added referencing SW-846. With the promulgation of 
    Update III, all of the methods in section 3.0 of part 266, appendix IX, 
    are now available in SW-846. Table 2 (BIF/EPA Methods) identifies the 
    methods in section 3.0 of part 266, appendix IX, and the equivalent SW-
    846 method. (Note: The method number has changed for some of the 
    methods to reflect the SW-846 method numbering system.) This technical 
    change was necessary to eliminate redundancy and to remove the 
    possibility that a discrepancy might exist between two versions of the 
    same method. This technical change only revises where the methods are 
    found; it does not change required or intended uses of the methods.
        Since these methods have been removed from appendix IX of part 266 
    and replaced with a note referencing SW-846, and since 
    Secs. 266.104(e)(1), 266.106(g) (1) and (2), and 266.107(f) refer 
    (directly or indirectly) to the methods in that appendix, the Agency 
    has also revised Secs. 266.104(e)(1), 266.106(g) (1) and (2), and 
    266.107(f) to refer to the equivalent methods of SW-846.

    C. Revision of Footnote 5 of Appendix IX to 40 CFR Part 264
    
        Appendix IX to 40 CFR part 264 contains the ground-water monitoring 
    list of analytes and suggested methods for analyte determination. 
    Footnote 5 to the appendix notes that the listing of suggested methods 
    refers to analytical procedure numbers used in SW-846. However, the 
    listing of suggested methods includes packed column GC methods, which 
    have been removed from SW-846 with the addition of Update III. The 
    Agency, therefore, has revised footnote 5 of appendix IX to 40 CFR part 
    264 to also note that the packed column methods were promulgated 
    methods through Update IIB of SW-846 and that, as of Update III, the 
    Agency has replaced the methods with capillary column GC methods.
    
    D. Removing the 47 Analytical Test Methods Incorporated by Reference in 
    Sec. 260.11(a)
    
        The Agency is today removing the list of 47 methods found at the 
    end of
    
    [[Page 32457]]
    
    Sec. 260.11(a). This action is being taken since the 47 methods are 
    contained in the Third Edition of SW-846, which is being incorporated 
    by reference today in its entirety. Therefore, specific reference to 
    the 47 methods in Sec. 260.11, Incorporation by Reference, is redundant 
    and unnecessary. It was the intent of the Agency to finalize this 
    action in a previous rulemaking (August 31, 1993, 58 FR 46040). 
    However, due to an error in the regulatory language contained in that 
    rule, the 47 methods were not removed from Sec. 260.11(a) at that time.
    
    E. Revising the Disclaimer and Chapter Two of SW-846 to Include 
    Clarifying Editorial Changes Regarding Flexibility Allowed During the 
    Use of SW-846 Methods
    
        The Agency believes that language in SW-846 which clarifies the 
    flexibility inherent to SW-846 methods is useful to the regulated 
    community. SW-846 methods are written so that they may be used as 
    quantitative trace analytical methods to demonstrate that a waste 
    ``does not contain'' constituents that require it to be managed as a 
    hazardous waste. If particular RCRA applications do not require this 
    rigor, looser analytical criteria may be applied, provided that they 
    satisfy the data quality requirements for the particular application. 
    Therefore, the Agency has revised the Disclaimer and Chapter Two of SW-
    846 to include editorial changes which explain that glassware, 
    reagents, supplies, equipment and settings other than those specified 
    in SW-846 may be employed, provided that method performance appropriate 
    for the intended RCRA application is documented. Such performance 
    includes consideration of precision, accuracy (or bias), recovery, 
    representativeness, comparability, and sensitivity (detection, 
    quantitation, or reporting limits) relative to the data quality 
    objectives for the intended use of the analytical results. In other 
    words, the Agency is following a Performance-Based Measurement System 
    (PBMS) approach where the analyst must be able to demonstrate the 
    ability to determine the analytes of concern in the matrix(ces) of 
    concern at the level (concentration) of concern for any particular RCRA 
    application. RCRA regulations basically specify ``what'' needs to be 
    determined and leaves the ``how'' up to the analyst. ``Any reliable 
    analytical method'' may be used for this demonstration. If in response 
    to this inherent flexibility an alternative analytical procedure is 
    employed, the laboratory should demonstrate and document that the 
    procedure is capable of providing the appropriate performance. The 
    Disclaimer and Chapter Two explain that the performance data included 
    in the SW-846 methods are not intended to be used as absolute QC 
    acceptance criteria for method performance. The data are intended to 
    only be guidance, by providing typical method performance in certain 
    representative matrices to assist the analyst in the selection of an 
    appropriate method for an intended RCRA application.
        The flexibility described in the Disclaimer and Chapter Two of SW-
    846 is applicable when any regulating entity (e.g., State Government) 
    specifies the use of methods found in SW-846. The following language 
    from the Preface and Overview should help clarify the flexibility 
    inherent in the SW-846 manual:
    
        The procedures described in this manual are meant to be 
    comprehensive and detailed, coupled with the realization that the 
    problems encountered in sampling and analytical situations require a 
    certain amount of flexibility. The solutions to these problems will 
    depend, in part, on the skill, training, and experience of the 
    analyst. For some situations, it is possible to use this manual in 
    rote fashion. In other situations, it will require a combination of 
    technical abilities, using the manual as guidance rather than in a 
    step-by-step, word-by-word fashion. Although this puts an extra 
    burden on the user, it is unavoidable because of the variety of 
    sampling and analytical conditions found with hazardous wastes.
    
        However, as explained in the Disclaimer and Chapter Two, this 
    flexibility does not apply to method-defined parameters where the 
    analytical result is wholly dependant on the measurement process, such 
    as during the use of the Toxicity Characteristic Leaching Procedure 
    (Method 1311) and other characteristic tests. In these instances, 
    changes to the specific methods may change the end result and 
    incorrectly identify a waste as non-hazardous. Therefore, when the 
    measurement of such method-defined parameters is required by 
    regulation, those methods are not subject to the flexibility afforded 
    to other methods.
    
    V. Overview of Final Rule
    
        This rule makes final the Agency's proposal to remove certain 
    methods and add revised methods and chapters and new methods as Update 
    III to SW-846 and to incorporate the Third Edition as amended by 
    Updates I, II, IIA, IIB, and III in 40 CFR 260.11(a) for use in 
    complying with the requirements of subtitle C of RCRA.
        Table 3, Final Update III of SW-846, Third Edition lists all of the 
    revised methods and chapters and new methods that are approved by the 
    Agency for inclusion in Final Update III to SW-846. The table lists the 
    chapters and methods of Update III in the order of their relative 
    location in SW-846. The vertical ``* * *'' notation indicates portions 
    of SW-846, Third Edition (as amended by Updates I, IIA, and IIB) which 
    are unchanged by Final Update III.

    VI. State Authority
    
        For these Regulatory cases where SW-846 is required, today's rule 
    provides standards that are not immediately effective in authorized 
    States since the requirements are being imposed pursuant to pre-HSWA 
    authority. See RCRA section 3006. The requirements will be applicable 
    only in those States that do not have final authorization. In 
    authorized States, the requirements will not be applicable until the 
    State revises its program to adopt equivalent requirements under State 
    law. Procedures and deadlines for State program revisions are set forth 
    in 40 CFR 271.21. 40 CFR 271.3 sets forth the requirements a State must 
    meet when submitting its final authorization application.
    
    VII. Effective Date
    
        Section 3010 of RCRA provides that regulations promulgated pursuant 
    to subtitle C of RCRA shall take effect six months after the date of 
    promulgation. However, HSWA-amended section 3010 of RCRA allows rules 
    to become effective in less than six months when, among other things, 
    the Agency finds that the regulated community does not need six months 
    to come into compliance. SW-846, as revised by Update III, inclusively 
    provides greater flexibility to the regulated community in testing and 
    monitoring solid waste by offering a greater selection of approved 
    methods and by promoting more flexibility in method application. In 
    addition, no method was deleted as part of Update III unless at least 
    one other approved replacement method was also readily available in SW-
    846. Therefore, the Agency believes that the regulated community does 
    not need six months to
    
    [[Page 32461]]
    
    come into compliance. For the same reasons, the Agency believes that 
    good cause exists under the Administrative Procedures Act, 5 U.S.C 
    section 553(d), for not delaying the effective date of this rule. 
    Therefore, this rule is effective June 13, 1997.
    
    VIII. Regulatory Analyses
    
    A. Executive Order 12866
    
        The Agency has determined that this rule is not a ``significant 
    regulatory action'' under the terms of Executive Order 12866 because 
    this rule does not create any new regulatory requirements and it does 
    not require any new reports beyond those now required. Therefore, this 
    rule is not subject to OMB review and the requirements of the Executive 
    Order.
    
    B. Unfunded Mandates Reform Act
    
        Title II of the Unfunded Mandates Reform Act of 1995 (UMRA or the 
    Act), Pub. L. 104-4, establishes requirements for Federal agencies to 
    assess the effects of their regulatory actions on State, local, and 
    tribal governments and the private sector. Under section 202 of UMRA, 
    EPA generally must prepare a written statement for rules with Federal 
    mandates that may result in estimated costs to State, local, and tribal 
    governments in the aggregate, or to the private sector, of $100 million 
    or more in any one year. When such a statement is required for EPA 
    rules, under section 205 of the Act, EPA must identify and consider 
    alternatives, including the least costly, most cost-effective or least 
    burdensome alternative that achieves the objectives of the rule. EPA 
    must select that alternative, unless the Administrator explains in the 
    final rule why it was not selected or it is inconsistent with law. 
    Before EPA establishes regulatory requirements that may significantly 
    or uniquely affect small governments, including tribal governments, it 
    must develop under section 203 of the Act 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 include a Federal 
    mandate that may result in estimated costs of $100 million or more to 
    State, local, and tribal governments in the aggregate, or to the 
    private sector, in any one year. This is due to the fact that this rule 
    simply revises available test methods for complying with existing 
    regulatory requirements, and in most cases, the SW-846 test methods are 
    provided as guidance, not requirements. Even where the use of a 
    specific test method is required, the Agency does not believe that the 
    revised methods will result in significant cost increases and indeed, 
    most of the revised methods are expected to result in reduced costs. 
    For example, new immunoassay methods can be run in the field, replacing 
    expensive gas chromatographic laboratory work; this will allow for more 
    and faster sampling, helping to reduce the cost of cleanups. Thus, 
    today's notice is not subject to the written statement requirements in 
    sections 202 and 205 of the Act.
        As for section 203 of the Act, today's rule is not expected to have 
    any ``unique'' effects on small governments; the only expected effects 
    on a small government would be where that government is itself managing 
    hazardous wastes, and is using one or more test methods for complying 
    with RCRA regulations. Further, for the reasons set out in the prior 
    paragraph, the revised test methods would not be expected to have a 
    ``significant'' effect on small governments (or other users of test 
    methods). Thus, today's notice is not subject to the requirements of 
    section 203 of the Act.
    
    C. Certification Under the Regulatory Flexibility Act
    
        Pursuant to the Regulatory Flexibility Act, 5 U.S.C. 601-6012, 
    whenever an Agency is required to publish a general notice of 
    rulemaking for any proposed or final rule, it must prepare and make 
    available for public comment a regulatory flexibility analysis that 
    describes the impact of the rule on small entities (i.e., small 
    businesses, small organizations, and small governmental jurisdictions).
        The EPA has determined that this rule will not have a significant 
    economic impact on a substantial number of small entities. This rule 
    does not create any new regulatory requirements and it does not require 
    any new reports beyond those now required. Some of the methods found in 
    Update III to SW-846, Third Edition, are required by some of the 
    regulations under subtitle C of RCRA. Based on an evaluation of each of 
    those methods and the regulatory requirements, the Agency determined 
    that this update will not impose significant additional costs on any 
    member of the regulated community. In addition, SW-846 functions in 
    other situations as a guidance document and the net effect of an update 
    to the document is to provide greater flexibility and utility to all of 
    the regulated community, including small entities, by providing an 
    increased choice of appropriate analytical methods for RCRA 
    applications. Therefore, the EPA provides the following certification 
    under the Regulatory Flexibility Act, as amended by the Small Business 
    Regulatory Enforcement Flexibility Act. Pursuant to the provision at 5 
    U.S.C. 605(b), I hereby certify that this rule will not have a 
    significant economic impact on a substantial number of small entities. 
    Thus the rule, does not require an RFA.
    
    D. Submission to Congress and the General Accounting Office
    
        Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
    Regulatory Enforcement Fairness Act of 1996, EPA submitted a report 
    containing this rule and other required information to the U.S. Senate, 
    the U.S. House of Representatives and the Comptroller General of the 
    General Accounting Office prior to publication of the rule in today's 
    Federal Register. This rule is not a ``major rule'' as defined by 5 
    U.S.C. 804(2).
    
    E. Paperwork Reduction Act
    
        There are no additional reporting, notification, or recordkeeping 
    provisions associated with today's rule. Such provisions, were they 
    included, would be submitted for approval to the Office of Management 
    and Budget (OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et 
    seq.
