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

[[Page 488]]

6860. 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.
