    -----------------------------------------------------------------------
    
    SUMMARY: The U.S. Environmental Protection Agency is providing notice 
    of, and invites comment on, its intent to reform implementation of 
    RCRA-related monitoring by formally adopting a performance-based 
    measurement system (PBMS), by improving public outreach and 
    communication, and by improving availability and distribution of the 
    EPA-approved test methods manual ``Test Methods for Evaluating Solid 
    Waste, Physical/Chemical Methods'', EPA Publication SW-846. 
    Implementation of PBMS will include a proposal to change certain RCRA 
    regulations so that the exclusive use of SW-846 methods will no longer 
    be required. EPA is also announcing the availability of, and requests 
    comment on, ``Draft Update IVA'' to the Third Edition of SW-846, which 
    contains new and revised methods. EPA also requests comment on deleting 
    several individual methods and integrating them into two comprehensive 
    methods, and removing Chapter Eleven from SW-846.

    I. Background
    
        The 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 monitoring conducted in support of 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, to satisfy 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 as updates to 
    support changes in the regulatory program and to improve method 
    performance and cost effectiveness. To date, EPA has finalized Updates 
    I, II, IIA, IIB, and III to the SW-846 manual, and the updated and 
    fully integrated manual contains approximately 3500 pages.
    
    II. Notice of Agency Intent to Reform Implementation of RCRA-
    Related Monitoring
    
        EPA is actively working to implement the President's program for 
    reinventing government and reforming regulatory policy. In order to 
    meet goals related to this important effort, EPA is considering reform 
    of the implementation of monitoring under the RCRA Program. The goals 
    include the timely and efficient promotion and approval of monitoring 
    technologies, increased flexibility regarding regulatory compliance 
    (i.e., flexibility in analytical method selection), and improvements in 
    public communication (e.g., to educate the public regarding new efforts 
    and to dispel any misconceptions regarding the use of SW-846).
        The following subsections provide notice of and describe actions to 
    be undertaken by EPA in an effort to meet the aforementioned goals.
    
    A. Adoption of PBMS in the RCRA Program
    
        On October 6, 1997, EPA published a Notice of Intent, notifying the 
    public of the Agency's plans to implement performance-based measurement 
    systems (PBMS) for environmental monitoring in all of its media 
    programs to the extent feasible (see 62 FR 52098). Some members of the 
    regulated community and Congress have suggested that EPA needs to 
    change the way it specifies monitoring requirements in regulations and 
    permits, in a manner which allows more flexibility and promotes the use 
    of new technologies. EPA supports this position and is committed to 
    incorporating the PBMS approach in media monitoring, to the extent 
    feasible, including monitoring conducted in support of RCRA.
        Basically, PBMS conveys ``what'' needs to be accomplished, but not 
    prescriptively ``how'' to do it. EPA 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 a 
    performance-based approach, the regulating entity will specify 
    questions to be answered by the monitoring process, the decisions to
    
    [[Page 25432]]
    
    be supported by the data, the level of uncertainty acceptable for 
    making the decisions, and the documentation to be generated to support 
    the PBMS approach in the RCRA Program. The criteria may be published in 
    regulations, technical guidance documents, permits, work plans, or 
    enforcement orders. Data producers will demonstrate that a proposed 
    sampling and analytical approach meets the monitoring criteria 
    specified in the Quality Assurance Project Plans or Sampling and 
    Analysis Plans for the individual projects or applications.
        EPA believes that the PBMS approach will provide many benefits to 
    both regulators and the regulated community when conducting monitoring 
    for compliance with the RCRA regulations or for general information 
    gathering. The benefits include flexibility in method selection, 
    expedited approval of new and emerging technologies to meet monitoring 
    requirements, and the development and use of cost-effective methods. 
    Where PBMS is implemented, the regulated community will be able to 
    select an appropriate analytical method for use in complying with EPA's 
    RCRA regulations, including any method not found in EPA-published 
    method manuals that is both cost-effective and meets the data quality 
    objectives of the particular project for which it is being used.
        It is EPA's intent that implementation of PBMS have the overall 
    effect of both improving data quality and encouraging the advancement 
    of analytical technologies. Therefore, EPA has been working at breaking 
    down barriers to using new and innovative monitoring techniques, 
    including requirements to use specific measurement methods or 
    technologies when complying with some of the RCRA regulations. As part 
    of EPA's efforts to implement PBMS, and thus reform monitoring under 
    the RCRA Program, the following actions are planned:
    --Incorporating the PBMS philosophy into new regulations.
    --Establishing data quality and performance requirements for RCRA-
    required monitoring and including the requirements in the RCRA 
    regulations, as necessary, to assist the regulated community in method 
    selection and help assure successful PBMS implementation.
    --Developing new sampling and testing methodologies which are 
    compatible with the PBMS approach and encouraging use of those methods.
    --Working with other regulating entities to help assure that the 
    regulated community benefits from the flexibility of the PBMS approach 
    at all regulating levels of the RCRA Program, when practical and 
    feasible.
    --Fostering training and guidance to educate regulators and the 
    regulated community regarding the flexibility of PBMS, the inherent 
    flexibility of SW-846, and application of PBMS during RCRA-related 
    monitoring.
    --Removing some of the required uses for SW-846 methods from the RCRA 
    regulations, where the Agency believes these requirements are not 
    necessary (in order to facilitate PBMS implementation), and thus 
    removing regulatory barriers to the use of new and innovative 
    technologies for RCRA-related monitoring.
        The Agency is interested in comments regarding PBMS implementation 
    within the RCRA Program. In particular, EPA is interested in receiving 
    public comment in response to the following questions:
        1. Will EPA's implementation of PBMS provide adequate flexibility 
    in method selection and facilitate the use of new technologies?
        2. What Agency actions during the process of changing to PBMS 
    within the RCRA Program would particularly assure a smooth transition 
    (including actions related to public notice and the training of 
    affected parties)?
        3. What are the perceived technical and programmatic barriers to 
    effective PBMS implementation in the RCRA Program and what Agency 
    actions might be effective in removing these barriers?
        4. What might be the economic impact (additional costs and cost 
    savings) on the regulated community and other entities (e.g., small 
    businesses) as a result of PBMS implementation in the RCRA Program?
        5. What concerns exist regarding establishment of the data quality 
    and performance requirements for RCRA-required monitoring that are 
    necessary to adequately assist the regulated community in method 
    selection and assure successful PBMS implementation?
        6. How might the Agency best work with other regulating entities 
    (e.g., states) to maximize the regulated community's benefits from the 
    flexibility provided by the PBMS approach?
        7. What concerns exist regarding the impact of PBMS implementation 
    on state programs?
        8. What concerns exist regarding the potential effect of PBMS on 
    compliance monitoring and enforcement of RCRA-related regulatory and 
    statutory requirements? What might be the positive or negative impacts 
    of PBMS on compliance monitoring and enforcement, including regarding 
    facility inspections?
        9. What might be the environmental benefits that may be achieved 
    through implementation of PBMS within the RCRA program?
    
    B. Removing the Required Uses of SW-846 Methods From the RCRA 
    Regulations
    
        As noted in the previous section, EPA intends to implement PBMS to 
    the extent feasible for RCRA-related monitoring. One barrier to 
    successful PBMS implementation is the current requirement to use 
    specific measurement methods or technologies in complying with 
    regulations. Some RCRA regulations require the use of specific SW-846 
    methods or SW-846 in general. As explained below, EPA believes that 
    some of these regulatory restrictions on methods may no longer be 
    necessary and run counter to EPA's intent to adopt PBMS for RCRA-
    related monitoring.
        Several of the regulations require the use of specific SW-846 
    methods for defining the particular regulatory parameters. Such 
    requirements are referred to as ``method-defined parameters.'' For 
    example, 40 CFR 261.24(a) requires the use of SW-846 Method 1311, the 
    Toxicity Characteristic Leaching Procedure, to determine if a waste 
    exhibits the toxicity characteristic. In those cases, the method itself 
    is the regulation and a method change or substitution cannot be 
    accomplished without undermining the substantive requirement 
    demonstrated by the method. These required uses of SW-846 methods are 
    necessary.
        Several other RCRA regulations require the use of SW-846 methods 
    where those methods do not define the particular regulatory parameter. 
    Most required uses of SW-846 methods fall under this category. An 
    example is 40 CFR 260.22(d)(1)(I), which currently requires the use of 
    only SW-846 methods in support of a petition to amend part 261 to 
    exclude (``delist'') a waste listed with code ``T'' in subpart D of 40 
    CFR part 261. EPA believes that these types of required uses of SW-846 
    methods may not be necessary.
        As a result of the requirements to use SW-846 methods, all final 
    SW-846 updates must be issued by rulemaking. This often delays the 
    availability of needed new or revised methods. In addition, requiring 
    the use of SW-846 methods discourages or impedes the use of new and 
    innovative methods which are both cost-effective and capable of meeting 
    data quality objectives.
        Therefore, EPA is considering publishing in the near future a 
    proposal in the Federal Register to remove
    
    [[Page 25433]]
    
    required uses of SW-846 methods from the RCRA subtitle C regulations 
    for all purposes other than the determination of method-defined 
    parameters. The Agency would take this action as part of its efforts to 
    implement PBMS for RCRA-related monitoring. This action would also 
    remove the need to engage in rulemaking for every SW-846 update and 
    would allow the updates to be issued as revisions to a guidance 
    document, which was what SW-846 was originally intended to be. This 
    action should promote the timely incorporation of new and innovative 
    technologies into the RCRA Program.
        The Agency is interested in receiving comments at this time 
    regarding its plan to remove certain required uses of SW-846 methods 
    from the RCRA regulations, as described above. In particular, EPA is 
    interested in public comment in response to the following questions:
        1. Are any of the required uses of SW-846 methods in the RCRA 
    regulations for other than method-defined parameters necessary?
        2. What might be the economic impact on the regulated community and 
    other entities (e.g., small businesses) as a direct result of the 
    removal of certain required uses of SW-846 methods?
        3. What concerns exist regarding implementation and enforcement of 
    the allowed use of ``other appropriate methods'' in lieu of a specific 
    SW-846 method for RCRA-related monitoring?
        4. What concerns exist regarding the impact on state RCRA programs 
    of the removal of certain required uses of SW-846 methods from the 
    Federal RCRA regulations?
    
    C. Changing the Approach for Releasing SW-846 Updates and Changing the 
    Method Evaluation Process
    
        Assuming that the rule to remove the required use of most SW-846 
    methods is finalized, as described in the previous section, EPA is 
    considering the use of rulemaking only for those updates to SW-846 
    which include methods used for method-defined parameters. Rulemakings 
    for those method updates will remain necessary because the required 
    uses of those methods will remain in the RCRA regulations. All other 
    SW-846 updates will be finalized more efficiently as guidance, such as 
    by releasing a draft SW-846 update in conjunction with publication of a 
    Federal Register document with an invitation for public comment before 
    finalizing the update. The Agency may also use other means of update 
    release and public notification to assure that reliable, innovative 
    methods are provided to the regulated community in a timely and cost-
    effective manner.
        At a minimum, future procedures for releasing new SW-846 methods 
    will include a critical method evaluation process, in order to continue 
    to assure the publication of reliable methods for the RCRA Program. 
    Peer input and review, internal and external, are already in place 
    within the RCRA monitoring program to ensure that its products (e.g., 
    new SW-846 methods) are based upon the best current knowledge from 
    science and judged credible by those who deal with the products. 
    Currently, the Agency receives peer input regarding any method 
    considered for inclusion in SW-846 from an internal technical work 
    group composed of national expert-level chemists and sometimes external 
    experts, as required based on the necessary expertise. To augment this 
    process, the Agency is considering an approach whereby additional 
    relevant experts from outside the program are invited to evaluate new 
    methods, through peer review or another advisory process. Such 
    reviewers or advisors might include both internal (from within EPA) or 
    external (outside EPA) peers of the program staff. The new process is 
    expected to include a critical evaluation of a final new method, before 
    its release, whereby formal comments are submitted and a review record 
    created and maintained.
        The Agency is interested in comments regarding possible alternative 
    approaches to SW-846 update releases, if, as mentioned above, the rule 
    to remove certain required uses of SW-846 methods is finalized. 
    Specifically:
        1. Should EPA continue to solicit public comments on SW-846 
    methods? Should the Agency use more timely means of releasing updates 
    other than Federal Register documents and under what circumstances 
    would such procedures be preferred or necessary?
        2. What future mechanism should be used to assure adequate and 
    quality review of methods? How could EPA best make use of peer review 
    or another advisory process in the development of guidance and methods 
    for RCRA-related monitoring?
    
    D. Improving SW-846 Availability to the Public
    
        In order to further promote the availability of RCRA-related 
    monitoring technologies, EPA is considering an SW-846 distribution 
    approach which offers more choices to the public for obtaining SW-846 
    methods. For most of the history of SW-846, the public received paper 
    copies of SW-846 through a subscription service with the Government 
    Printing Office (GPO), or the public purchased paper copies of any 
    portion of the manual at any time through the National Technical 
    Information Service (NTIS).
        In response to requests for electronic versions of the SW-846 
    methods, EPA published in 1996 a CD-ROM version of the manual for sale 
    from NTIS. EPA and NTIS recently completed Version 2 of the SW-846 CD-
    ROM, which includes the manual as revised through Update III. The SW-
    846 CD uses Adobe Acrobat Reader with Search, supplied with the CD, to 
    view the SW-846 methods and chapters. As explained below, EPA is also 
    planning to offer all of the SW-846 methods and chapters on the 
    Internet, without the Adobe Acrobat search feature.
        The Internet is another means used today by EPA to distribute 
    documents electronically to the general public. EPA has established a 
    policy of placing official rulemakings and related background documents 
    in support of the rulemakings on the Internet. The public has expressed 
    an interest in receiving SW-846 documents for free on the Internet, and 
    in response EPA has decided to make SW-846 available on the Internet in 
    the near future. SW-846 is very large, both in number of documents and 
    electronic file size (several methods contain many imported diagrams 
    and flow charts). EPA is interested in determining whether the 
    downloading of the entire manual from the Internet will be too timely 
    or otherwise impractical or difficult for most Internet users. If the 
    Agency determines that having the current SW-846 on the Internet 
    provides a valuable service to the public, then EPA will make 
    subsequent SW-846 updates, and other relevant testing protocols and 
    documents, available on the Internet.
        EPA is requesting comment on the effectiveness of the above means 
    to distribute SW-846. The Agency is also interested in other ideas for 
    making SW-846 methods more available. The Agency understands that 
    making SW-846 available on the Internet without cost may alleviate the 
    need to purchase paper versions of the manual.
    
    E. Improving Public Outreach and Communication Regarding SW-846 and 
    RCRA-Related Monitoring
    
        The Agency currently uses many different means (e.g., Federal 
    Register documents, training, and symposia) to inform the public of 
    important activities within its programs. EPA is considering an 
    approach which both maintains and supplements these means of public 
    communication in a manner that
    
    [[Page 25434]]
    
    improves public outreach and communication regarding SW-846 and RCRA-
    related monitoring. EPA believes that improving public outreach will 
    promote public preparedness and understanding regarding the reforms 
    discussed in sections II.A through II.C. The Agency also believes that 
    improved outreach efforts will help dispel any misconceptions regarding 
    SW-846 and RCRA-related monitoring. The paragraphs to follow describe 
    some of the communication and outreach efforts which the Agency is 
    considering maintaining or expanding. EPA is interested in public 
    comment regarding these efforts and suggestions for other means to 
    improve public outreach and education.
        The Agency remains open to the needs and interests of environmental 
    laboratories and the regulated community and is interested in receiving 
    comment on those needs and interests. Specifically, EPA wants to 
    facilitate communication and work directly with the laboratories and 
    the regulated community regarding the application of SW-846 methods. 
    The Agency hopes that this increase in communication will both assure 
    the correct interpretation of SW-846 methods and facilitate the 
    resolution of any problems with method application. For example, EPA is 
    currently working with the International Association of Environmental 
    Testing Laboratories (IAETL) Section of the American Council of 
    Independent Laboratories (ACIL) regarding the application of certain 
    SW-846, Update III methods.
        EPA also intends to continue to work with outside organizations or 
    individuals in developing new methods for inclusion in SW-846. EPA 
    developed and currently maintains a variety of partnerships with many 
    sectors of the environmental analytical community (such as other 
    Federal Agencies, private industry, State agencies, Consensus Standard 
    Organizations, and academic institutions) to develop various analytical 
    techniques for SW-846 such as microwave digestion, immunoassay, and 
    field portable XRF methods, to name a few. For example, EPA is 
    currently working with the private sector in the development of 
    additional SW-846 screening methods for organic analytes.
        As part of its efforts to increase the role of the scientific 
    community in the implementation of monitoring under the RCRA and 
    Comprehensive Environmental Response, Compensation, and Liability Act 
    (CERCLA) Programs, EPA joined in a partnership with the American 
    Chemical Society to annually sponsor the Waste Testing and Quality 
    Assurance (WTQA) Symposium. The symposium was initiated in 1985 as part 
    of EPA's efforts to foster a partnership among EPA, the regulated 
    community, the public, State regulatory agencies, and other members of 
    the RCRA and CERCLA monitoring community. Attendees have an opportunity 
    at the symposium to share new monitoring approaches and technologies 
    and to contribute to discussions regarding regulatory issues and 
    initiatives. The WTQA currently has three goals: (1) to serve as a 
    forum for all interested parties to work together to solve RCRA and 
    CERCLA environmental monitoring and waste characterization problems in 
    a cost-effective manner, (2) to give State regulatory agencies and the 
    public timely information about EPA activities that might affect their 
    programs, and (3) to permit the members of the monitoring community an 
    opportunity to exchange information and experiences in using both 
    existing and new monitoring methods and approaches. Thus, the WTQA 
    Symposium has always served as an effective means to educate the public 
    and regulators regarding the inherent flexibility of SW-846 methods and 
    to foster new technology development. It has also always served as an 
    effective forum for feedback regarding successes and failures during 
    monitoring and to disseminate knowledge regarding new and modified 
    approaches and their performance in the real-world.
        The Agency will continue to annually sponsor the WTQA Symposium. 
    The WTQA Symposium will be held this year (1998) on July 13 through 15 
    at the Marriott Crystal Gateway in Arlington, Virginia. This year's 
    symposium will focus on PBMS implementation and its potential impact on 
    the regulated community and testing laboratories. EPA plans to hold 
    issue workshops on PBMS and perhaps regarding other reforms to RCRA-
    related monitoring. Attendees will also learn about the newest 
    laboratory methods associated with environmental monitoring and quality 
    assurance/quality control (QA/QC), and about how changes regarding 
    monitoring conducted in support of EPA's programs will affect their 
    operations.
        The Methods Information Communication Exchange (MICE) Service, or 
    ``Hotline,'' is another existing means that the Agency uses to 
    communicate with the public regarding RCRA-related monitoring. The MICE 
    Service provides timely answers to method-related questions and takes 
    comments via the telephone, fax, or e-mail. Chemists, ground-water 
    specialists, and sampling experts who are knowledgeable in SW-846 
    procedures are directly available through the MICE Service to the 
    public and regulators involved in RCRA-related monitoring. People 
    interested in using the MICE Service call a voice mail answering 
    service that is available 24 hours per day, 7 days a week. The caller 
    can listen to several recorded messages on common SW-846 topics and 
    subsequently leave a message containing a question regarding an SW-846 
    method or related topic. The messages are retrieved each working day 
    and, after a review of the questions and any necessary research, the 
    MICE Service provides a response.
        The MICE Service also acts as an effective means to educate members 
    of the public directly regarding inherent method flexibility and to 
    clarify whether a method is required by a RCRA regulation. The service 
    therefore can be used in the future to help assure the proper 
    application of SW-846 methods from a PBMS standpoint. The MICE Service 
    also documents existing misconceptions or issues regarding SW-846 
    methods, and thus serves as a first step in identification and 
    resolution of some issues. Because of its unique and immediate means of 
    public outreach and education, EPA will continue to sponsor the MICE 
    Service. Instructions regarding contacting the MICE Service can be 
    found under the section of this document entitled FOR FURTHER 
    INFORMATION CONTACT.
        The Agency also authors articles for publication in professional 
    periodicals as a means to educate the public and regulators regarding 
    news-worthy topics. The staff of EPA's Office of Solid Waste (OSW) 
    frequently contribute articles to environmental magazines and journals 
    regarding SW-846 and other topics related to monitoring in support of 
    RCRA regulations. The articles educate and inform the public regarding 
    new analytical or sampling methodologies, SW-846 and the regulatory 
    process, the inherent flexibility of SW-846 methods, and the status of 
    various updates to SW-846.
        EPA will continue to use magazine and journal articles as a means 
    to help dispel misconceptions by regulators and the regulated community 
    regarding SW-846 flexibility and to clarify EPA's policy on method 
    flexibility and PBMS. OSW has submitted articles which educate the 
    public regarding the implementation of PBMS. Specifically, an article 
    in ``Environmental Lab'' by two staff members of the Methods Team of 
    OSW included two PBMS-related sections entitled ``Method Flexibility
    
    [[Page 25435]]
    
    and the Performance-Based Measurement System (PBMS)'' and ``Method 
    Flexibility and PBMS Initiatives.'' Other publications to which OSW 
    submits articles include the bi-monthly ``Environmental Testing and 
    Analysis,'' which includes a new EPA-OSW Methods Update feature, and 
    the bi-weekly ``Environmental Laboratory Washington Report.''
        As another means to provide timely communications to interested 
    parties, EPA presently lectures and conducts presentations in both this 
    country and abroad regarding innovative analytical technologies, new 
    analytical strategies and issues regarding RCRA-related monitoring. EPA 
    also provides training courses regarding monitoring under the RCRA 
    Program. The training course entitled ``Analytical Strategy for the 
    RCRA Program: A Performance-Based Approach'' is currently taught by OSW 
    staff to Regional, State and symposium (e.g., WTQA) audiences with the 
    intent to clarify the monitoring flexibility allowed by SW-846 methods 
    and the RCRA regulations and to promote and explain PBMS. Basically, 
    the training course explains: (1) the regulatory aspects of RCRA 
    analyses; (2) the role of SW-846, its organization and method format, 
    and its correct application for RCRA-related monitoring; and (3) the 
    factors to be considered in the selection of appropriate analytical 
    methods, especially within the context of a PBMS approach.
        EPA is considering increasing the availability of Agency-sponsored 
    training, lectures, and presentations to the public, Regions, and 
    States regarding SW-846 and other topics, such as PBMS, related to 
    monitoring conducted in support of RCRA regulations. EPA is also 
    planning to provide training regarding the implementation of PBMS to 
    the Regions and other affected entities. In the future, EPA hopes to 
    provide RCRA-related training to the regulated community both in person 
    and via video or satellite broadcast.
        Finally, EPA intends to use press releases and/or memoranda to 
    announce time-sensitive milestones related to SW-846 and monitoring 
    under the RCRA Program. For example, EPA is issuing a press release to 
    announce the availability of Draft Update IVA of SW-846, referring the 
    readers to this document. In addition, assuming the rule to remove 
    certain required uses of SW-846 methods from the RCRA regulations is 
    finalized (see section II.B above), the Agency is considering the use 
    of workshops, peer review panels, and/or public meetings as mechanisms 
    for disseminating information regarding new and revised SW-846 methods 
    and chapters.
        The Agency is interested in comments from the public on all of the 
    above means (e.g, the WTQA Symposium, MICE Service, the use of journal 
    articles, and training courses) for improving public outreach and 
    communication regarding RCRA-related methods and monitoring. For 
    example, the Agency is interested in whether the public believes the 
    WTQA Symposium would benefit from merging with other EPA programs, and 
    is also interested in suggestions for improving the WTQA Symposium. EPA 
    would like comments regarding increasing the effectiveness and 
    availability of RCRA-related information and training for the public, 
    such as through video or satellite broadcast as mentioned above.
    
    III. Availability of Draft Update IVA and Invitation for Public 
    Comment
    
        This document also announces the availability of Draft Update IVA 
    to SW-846 and invites public comment on its content. EPA is publishing 
    this document for informational purposes only, and is not at this time 
    formally proposing to revise SW-846 by adding Update IVA or to 
    incorporate the update in the RCRA regulations for required uses. 
    Therefore, this document will not be used as a basis for a final rule 
    to update SW-846 or revise any regulation. EPA is attempting to make 
    these Agency-reviewed methods available to the public early, for 
    guidance purposes (i.e., the methods can be used in all applications 
    for which the use of SW-846 methods is not mandatory and for which they 
    are effective). In addition, as noted in section II above and explained 
    further at the end of this section, if the rule to remove certain 
    requirements to use SW-846 methods is finalized, the Agency will not 
    have to finalize certain SW-846 updates (including Draft Update IVA) 
    through the rulemaking process.
        The Draft Update IVA methods have passed EPA's Technical Workgroup 
    review, but have not been promulgated for inclusion in SW-846 and the 
    RCRA regulations. As noted in section II of this document, several 
    regulations under subtitle C of RCRA currently require that certain SW-
    846 methods be employed. Any reliable analytical method may be used to 
    meet other requirements in 40 CFR parts 260 through 270. The methods 
    listed in Draft Update IVA fall in the category of ``any reliable 
    method.'' They may currently be used in all applications for which the 
    use of SW-846 methods is not mandatory. The methods of Draft Update 
    IVA, however, cannot be used for compliance with required uses of SW-
    846 methods. The Agency also cautions the regulated community to obtain 
    permission from the appropriate regulating entity, if required under 
    State or local regulations, before using these methods for non-
    mandatory applications.
        Table 1 provides a listing of the fifteen revised SW-846 methods 
    and five revised chapters or other SW-846 documents found in Draft 
    Update IVA. Table 1 also identifies those parts of each method or 
    chapters on which the Agency is interested in receiving public comment. 
    EPA is interested in comments from the public on the identified parts 
    because some or all of their text represents significant revisions from 
    the promulgated version of the document currently in SW-846, as amended 
    by Updates I through III.
    
    (Note: Unless otherwise indicated as former sections, the section 
    numbers in Table 1 refer to the section numbers in the Draft Update 
    IVA version of the method.)
    
         Significant revisions include text deletions, additions, or other 
    revisions that change a method's procedure or the intent or meaning of 
    the text. Significant revisions do not include typographical or 
    grammatical corrections, table reformatting (where the information is 
    not changed), logical outgrowths of other revisions (e.g., the 
    renumbering of sections to account for the addition of a new section), 
    or other edits that are not substantive changes to text intent or the 
    analytical procedure (e.g., the replacement of ``Teflon''' with 
    ``PTFE''). Nonsignificant revisions also include the movement of 
    otherwise unchanged information to another appropriate location in the 
    method. For example, the order of some of the equipment listed in 
    section 4.0 of Method 8321B is different from that found in section 4.0 
    of Method 8321A; however, much of the equipment itself has not changed. 
    Therefore, Table 1 lists only those parts of section 4.0 of Method 
    8321B which have been significantly revised (e.g., new equipment 
    specifications). The Agency will, however, consider comments on the 
    reordering of otherwise unchanged information in the revised methods of 
    Update IVA.
        Table 2 provides a listing of the thirteen new SW-846 methods found 
    in Draft Update IVA. Since these are new methods, EPA is interested in 
    comments on the content of all sections or parts of the new methods.
        Finally, Table 3 identifies the forty-four methods to be integrated 
    or deleted from SW-846 as part of Draft Update IVA. All but one of 
    these methods are individual flame or graphite furnace
    
    [[Page 25436]]
    
    atomic absorption methods. The exception is Method 3810, ``Headspace'', 
    an obsolete headspace screening method which has been replaced by 
    Method 5021, ``Volatile Organic Compounds in Soils and Other Solid 
    Matrices Using Equilibrium Headspace Analysis.'' The Agency expects to 
    delete Method 3810 because it is no longer needed in SW-846 because 
    Method 5021 was recently added to SW-846 as part of Final Update III. 
    Method 5021 can be used for both quantitative analysis and screening 
    applications.
        The individual atomic absorption methods are being deleted as part 
    of Draft Update IVA because their inclusion is redundant given that 
    their procedures and target analytes have been fully integrated into 
    revised Method 7000B (see Table 1) or new Method 7010 (see Table 2), 
    the general methods for the techniques. The Agency is interested in 
    comments on these method integrations and deletions. As mentioned 
    earlier in section II of this notice, several regulations under 
    subtitle C of RCRA currently require that certain SW-846 methods be 
    employed. Therefore, the methods contained in Draft Update IVA, cannot 
    be used for compliance with required uses of SW-846 methods and remain 
    in effect until the rule to remove the required use of SW-846 methods 
    has been promulgated.

    IV. Basis for Making Draft Update IVA Available and Agency Plans 
    for Finalizing the Update
    
        For previous updates to SW-846, EPA published a notice of proposed 
    rulemaking in the Federal Register, requested public comment, and 
    subsequently published a notice of final rulemaking. This process was 
    necessary because, as noted above, the use of some of these methods is 
    required by some of the hazardous waste regulations under subtitle C of 
    RCRA. However, for Draft Update IVA, EPA is initially publishing a 
    document of its availability and inviting public comment on the Agency-
    reviewed methods and chapters.
        EPA believes that Draft Update IVA will be valuable to the public 
    as guidance, and thus has taken today's action to expedite its 
    availability, instead of delaying distribution of this update to 
    coincide with publication of a notice of proposed rulemaking. EPA 
    believes this approach will allow introduction of Draft Update IVA 
    methods to the public in a more timely manner than the proposal 
    process, without compromising the method review and approval process. 
    EPA also believes this approach will allow greater flexibility in the 
    use of guidance methods, for Regional, State, and local agencies as 
    well as industry; and will allow the regulated community an opportunity 
    to participate early in the method review process with the submittal of 
    comments on the draft methods. The Agency will consider all comments 
    received on Draft Update IVA.
        As noted in section II of this document, the methods in SW-846 are 
    currently required by some of the RCRA regulations. As also explained 
    in section II, EPA is planning to formally propose in the Federal 
    Register the removal from the RCRA regulations certain requirements to 
    use SW-846 methods. The Agency notes that none of the methods in Draft 
    Update IVA are required for use in defining the hazardous waste 
    characteristics. EPA expects that the methods and chapters of Draft 
    Update IVA will remain in their current Agency-reviewed form until the 
    SW-846 deregulatory rule is finalized. EPA hopes to then revise Draft 
    Update IVA, as appropriate, in response to public comment and plans to 
    publish a document of availability in the Federal Register for the 
    final update. The publication of a proposed and final rule in the 
    Federal Register for Update IVA will not be necessary once the 
    deregulatory rule has been finalized. Should the SW-846 deregulatory 
    rule be proposed but not finalized in a timely
    
    [[Page 25438]]
    
    manner and should EPA determine that promulgated versions of the Update 
    IVA methods are needed for compliance purposes, EPA will publish a 
    notice of proposed rulemaking and a final rulemaking for the update.
    
    V. Request for Comment on the Removal of Chapter Eleven From SW-846
    
        The hazardous waste management regulations for permitted facilities 
    (40 CFR 264) were promulgated in July 1982 under subtitle C of the 
    Solid Waste Disposal Act, as amended by the Resource Conservation and 
    Recovery Act (RCRA) of 1976, and the Hazardous and Solid Waste 
    Amendments of 1984 (HSWA). Subpart F under these regulations, Releases 
    From Solid Waste Management Units, sets forth performance standards for 
    ground-water monitoring systems at permitted hazardous waste land 
    disposal facilities. A manual was prepared by the Office of Solid Waste 
    to provide guidance for implementing the ground-water monitoring 
    regulations for regulated units contained in 40 CFR 264, subpart F, and 
    the permitting standards of 40 CFR 270. In 1986, EPA released two 
    documents relating to RCRA ground-water monitoring, specifically the 
    ``RCRA Groundwater Monitoring Technical Enforcement Guidance'' (TEG) 
    and Chapter Eleven of SW-846, entitled ``Groundwater Monitoring.'' In 
    November 1992, the Agency's Groundwater Monitoring Program revised the 
    technical procedures for TSDF compliance with ground-water monitoring 
    requirements and documented the procedures in a 1992 document entitled 
    ``RCRA Groundwater Monitoring Draft Technical Guidance.'' However, the 
    1986 version of Chapter Eleven of SW-846 was not updated at that time 
    in conjunction with the 1992 ground-water monitoring guidance, and thus 
    the chapter remains out of date. At the present time, most of the 
    regulated community is using the ground-water monitoring guidance 
    issued in 1992 as the standard for RCRA ground-water monitoring 
    compliance. Therefore, EPA would like to remove the outdated Chapter 
    Eleven of SW-846, and replace it with a referral to the most current 
    version of the ground-water monitoring guidance originally issued by 
    the Office of Solid Waste in 1992. The Agency is requesting comment on 
    this approach. EPA is currently updating the November 1992 ground-water 
    monitoring guidance. However, Chapter 11 will remain in SW-846 until 
    the rule to remove the required use of SW-846 has been finalized.
    
        Dated: April 24, 1998.
    Matthew Hale,
    Acting Director, Office of Solid Waste.
