How Do I Obtain Electronic Access to this Notice

The docket index and the notice are available on the Internet at: WWW: http://www.epa.gov/​epaoswer/​hazwaste/​test/​up4ba.htm.

How Is This Notice Organized?

We list below the order of the major sections of this notice.

I. What Is the Subject and Purpose of this Notice?

II. How Does This Notice Relate to EPA's Future Methods Development Efforts?

III. How Can I Use the Methods of Draft Update IVB?

IV. What Does Draft Update IVB Contain?

I. What Is the Subject and Purpose of this Notice?

We are announcing the availability of, and requesting public comment on, Draft Update IVB to “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW-846. SW-846 contains the analytical and test methods that we have 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.

We change the content of SW-846 over time as new information and data are developed. We continually review advances in analytical instrumentation and techniques and periodically incorporate such advances into SW-846 as method updates. These updates support changes in the regulatory program and improve method performance and cost effectiveness. We add new SW-846 methods to the manual, and replace existing methods with revised versions of the same methods to reflect the advances and new techniques. To date, we have finalized Updates I, II, IIA, IIB, III, and IIIA to the SW-846 manual. We proposed and finalized these updates as part of a rulemaking.

We are now developing the next update to SW-846. On May 8, 1998, we published a notice of availability for Draft Update IVA in the Federal Register (see 63 FR 25430-25438). We then began developing Draft Update IVB to the manual. As we finished the methods, we posted them on our Internet site at http://www.epa.gov/​SW-846. Today, with this notice, and as requested in the Senate Committee Report No. 106-410 regarding EPA's 2001 appropriations bill, we are publishing and requesting comment on Draft Update IVB, as published on the Internet and found in the docket to this notice.

II. How Does This Notice Relate to EPA's Future Methods Development Efforts?

We are releasing Draft Update IVB in a notice of availability for informational purposes. We are making these EPA-reviewed methods and revised chapters available to the public early, for guidance purposes. 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. We believe that Draft Update IVB will be valuable to the public as guidance because it makes new analytical technologies and improved procedures available for use. This approach will allow the regulated community and others an opportunity to participate early in the method review process with the submittal of comments on the draft methods. As we also explained regarding the release of Draft Update IVA in its notice of availability, we are not at this time formally proposing to revise SW-846 by adding Update IVB, or to incorporate the update in the RCRA regulations for required uses.

In addition, we expect to change our approach to releasing most SW-846 updates in the future. The notice for Draft Update IVA (see 63 FR 25430-25438) explains in detail the reasons for this change. To summarize, we continue to implement a performance-based measurement system (PBMS) in the RCRA program. As part of this effort, we are developing a proposed rule to remove unnecessary required uses of SW-846 methods from the RCRA regulations. If this rule is finalized, we will generally only require the use of a particular method when it is referenced specifically in a regulation. Examples of such a requirement include the SW-846 methods specified in the RCRA regulations to determine whether a waste exhibits a hazardous waste characteristic (see 40 CFR part 261, subpart C). Several other RCRA regulations generally require the use of only SW-846 methods, but do not define regulatory parameters. In these cases, we plan to propose revisions to those regulations whereby another acceptable method may be used, provided it uses reliable techniques that are accepted as such by the scientific community and provided that it can be demonstrated to be appropriate for its intended use, i.e., it meets the data quality objectives (DQOs) or measurement quality objectives (MQOs) of the specific project.

If the future proposed rule to remove unnecessary required uses is finalized, we will use rulemaking for only those updates to SW-846 which include methods that are specifically required by our regulations. Rulemaking to revise or add required methods will remain necessary because the required use of those specific methods will continue. We will publish all other future SW-846 updates as guidance. In this manner, we will make most new and revised methods for RCRA-related monitoring available to the public in a faster and more efficient manner. We will still follow Agency guidelines to ensure that SW-846 methods are scientifically sound, including the peer review of method documents as necessary. We will also continue to request public comment on methods through Federal Register notices prior to their incorporation into SW-846.

III. How Can I Use the Methods of Draft Update IVB?

Although the Draft Update IVB methods passed our Technical Workgroup review, you cannot use the methods of Draft Update IVB for compliance with the regulations that require the use of SW-846 methods. However, there are other sampling and analysis requirements in 40 CFR parts 260 through 270 that do not specify the use of SW-846 methods and in those cases you may use any reliable analytical method, including the methods found in Draft Updates IVA and IVB. We recommend that you consult with the appropriate regulating entity before using these methods to comply with a regulation. Start Printed Page 70680

IV. What Does Draft Update IVB Contain?

Draft Update IVB contains revised and new documents for SW-846, each of which is dated “November 2000” in its footer. Tables 1 through 3 list the documents found in Draft Update IVB.

Table 1 provides a listing of the fifteen revised SW-846 methods and seven revised chapters or other SW-846 documents found in Draft Update IVB. We request public comment on all revised sections identified by Table 1. We are interested in comments from the public on the identified sections and chapters because some or all of their text represents significant revisions from the promulgated version of the document currently in the Third Edition of SW-846, as amended by Updates I through IIIA. (Note: Unless otherwise indicated as former sections, the section numbers in Table 1 refer to the section numbers in the Draft Update IVB 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. We will, however, consider comments on the reordering of otherwise unchanged information in future revisions of Draft Update IVB.

As indicated in Table 1, some of the revised methods were also in Draft Update IVA (documents dated January 1998). Based on further review, we revised those documents and are releasing them again as part of Draft Update IVB. You should replace your Draft Update IVA versions with the Draft Update IVB versions. These documents include the Table of Contents, Chapters Two through Five, and Methods 3535A, 3545A, 8081B, 8082A, 8141B, and 8321B (see Table 1 for the titles of these methods).

Table 2 provides a listing of the twelve new SW-846 methods found in Draft Update IVB. EPA is interested in comments on the content of all sections or parts of the new methods. Finally, Table 3 identifies the four air methods for which we are providing references in SW-846 as part of Draft Update IVB. These one-page references for each method indicate how one may obtain a copy of the method. We want to provide this information in SW-846, for the convenience of the user, because the methods are referred to by the RCRA regulations.
