C. How Is the Rest of This Notice Organized?

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

II. What is the Subject and Purpose of this Notice?

III. Why is this Update to SW-846 Being Announced in a Notice Instead of Being Promulgated as a Final Rule?

IV. What Does Final Update IV Contain?

II. What Is the Subject and Purpose of This Notice?

We are announcing the availability of Final Update IV to “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW-846. Final Update IV of SW-846 contains analytical methods that we have evaluated and determined to be appropriate and may be used for monitoring or complying with the RCRA hazardous waste regulations.

The Agency revises 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 by adding new methods to the manual, and replacing existing methods with revised versions of the same method. These updates improve analytical method performance and cost effectiveness. To date, we have finalized Updates I, II, IIA, IIB, III, IIIA, and IIIB to the SW-846 manual, which can be found on the Internet at: http://www.epa.gov/​epaoswer/​hazwaste/​test/​sw846.htm.

On May 8, 1998, we published a notice of availability for Draft Update IVA in the Federal Register (see 63 FR 25430-25438, Docket No. F-98-4TMA-FFFF) and, on November 27, 2000, we published a notice of availability for Draft Update IVB in the Federal Register (see 65 FR 70678-70681, Docket No. F-2000-4BTA-FFFF). In today's notice, we are announcing the availability of Final Update IV, which combines Draft Updates IVA, IVB, and subsequent revisions made to these Updates based on public comments received.

III. Why Is This Update to SW-846 Being Announced in a Notice Instead of Being Promulgated as a Final Rule?

In the past, EPA proposed and finalized updates to SW-846 as part of a rulemaking. On June 14, 2005, however, EPA published a final rule, referred to as the Methods Innovation Rule (MIR), which removed from the RCRA hazardous waste regulations any requirement to use an analytical method found in SW-846, unless that method is the only one capable of measuring a method-defined parameter (MDP) (70 FR 34538-34592). See the preamble of that rule regarding the Agency's basis for that rulemaking. In addition, the MIR allows the Agency to issue final updates to SW-846 as guidance, provided the analytical methods contained in the update are not required by the RCRA hazardous waste regulations. The Agency will continue to follow Agency guidelines to ensure that methods incorporated into SW-846 are scientifically sound, including the peer review of method documents, as appropriate. We will also continue to request public comment on methods we update through Federal Register notices prior to their incorporation into SW-846.

As the analytical methods contained in Final Update IV are not required by the RCRA hazardous waste regulations, EPA is issuing this update as guidance. EPA solicited public comments on the analytical methods found in Final Update IV in two Federal Register notices (see notice of availability for Draft Update IVA of SW 846 (63 FR 25430) and Draft Update IVB of SW-846 (65 FR 70678)). The docket to Final Update IV (EPA-RCRA-2006-0833) contains a background document with our response to public comments.

IV. What Does Final Update IV Contain?

Final Update IV contains new and revised analytical methods, each dated “February 2007” in its footer. The new and revised analytical methods can be found at: http://www.epa.gov/​epaoswer/​hazwaste/​test/​main.htm. Tables 2 through 4 list the documents found in Final Update IV. Table 5 lists those methods that have been deleted.

Table 2 provides a listing of the twenty-four revised SW-846 analytical methods, seven revised chapters and the table of contents and title page. Chapter Eleven (“Ground Water Monitoring”) is included in this listing because, as described in the Draft Update IVA notice, EPA has removed the outdated text of Chapter Eleven of SW-846 and replaced the text with a note to refer the reader to the most current version of the ground-water monitoring guidance originally issued by EPA's Office of Solid Waste (OSW) in 1992.

Table 3 provides a listing of twenty-three new analytical methods found in Update IV. It should be noted that two of the analytical methods (Methods 4500 and 9058) on which the Agency solicited public comment in Draft Updates IVA and IVB are not included in Final Update IV. Specifically, Method 4500, “Mercury in Soil by Immunoassay,” a method in Draft Update IVA, is not included because the method kit is no longer available from its original source. Method 9058, “Determination of Perchlorate Using Ion Chromatography with Chemical Suppression Conductivity Detection,” a method in Draft Update IVB, is not included because EPA determined, based on public comment and other source information, that this version of the analytical method is subject to biased results due to matrix interferences. However, the Agency developed two new and improved analytical methods for perchlorate analyses, SW-846 Methods 6850 and Start Printed Page 4886860. These methods are not part of the Final Update IV package, but have been validated and are available for use at the EPA Methods Web site, under the heading “New Methods,” http://www.epa.gov/​SW-846. Given the development and availability of Methods 6850 and 6860, EPA recommends that Method 9058 only be used for screening or long-term monitoring purposes. Confirmation of perchlorate detection is recommended when analyzing unfamiliar samples using an additional technique. EPA currently plans to include a final version of Method 9058 in the Fourth Edition of SW-846 after additional validation. The final version will also be posted on the EPA Methods Web site if the method is completed prior to official publication of the Fourth Edition.

Table 4 identifies three air sampling methods for which we are providing references in SW-846 as part of Final Update IV. These one page references indicate how one may obtain a copy of each method. We are providing this information in SW-846, for the convenience of the reader.

Finally, Table 5 identifies the forty-four analytical methods to be integrated or deleted from SW-846 as part of Final Update IV. All but one of these analytical methods is an individual flame or graphite furnace atomic absorption method. The exception is Method 3810, “Headspace,” an obsolete headspace screening method which was replaced by Method 5021, “Volatile Organic Compounds in Soils and Other Solid Matrices Using Equilibrium Headspace Analysis.” The Agency is deleting Method 3810 because Method 5021, added to SW-846 as part of Final Update III, can be used for screening applications (in addition to quantitative uses), and can be expected to perform better than Method 3810 as a screening method. The 43 individual atomic absorption methods are being deleted because their inclusion is redundant given that their procedures and target analytes are fully integrated into revised Method 7000B (see Table 2) or new Method 7010 (see Table 3), the general methods for the atomic absorption techniques.
