ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 141
[EPA-HQ-OW-2011-0413; FRL-9322-3]
Expedited Approval of Alternative Test Procedures for the
Analysis of Contaminants Under the Safe Drinking Water Act; Analysis
and Sampling Procedures
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This action announces the Environmental Protection Agency's
(EPA's) approval of alternative testing methods for use in measuring
the levels of contaminants in drinking water and determining compliance
with national primary drinking water regulations. The Safe Drinking
Water Act (SDWA) authorizes EPA to approve the use of alternative
testing methods through publication in the Federal Register. EPA is
using this streamlined authority to make 11 additional methods
available for analyzing drinking water samples required by regulation.
This expedited approach provides public water systems, laboratories,
and primacy agencies with more timely access to new measurement
techniques and greater flexibility in the selection of analytical
methods, thereby reducing monitoring costs while maintaining public
health protection.
DATES: This action is effective June 24, 2011.

SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this action apply to me?
Public water systems are the regulated entities required to measure
contaminants in drinking water samples. In addition, EPA Regions as
well as States and Tribal governments with authority to administer the
regulatory program for public water systems under SDWA may also measure
contaminants in water samples. When EPA sets a monitoring requirement
in its national primary drinking water regulations for a given
contaminant, the Agency also establishes in the regulations
standardized test procedures for analysis of the contaminant. This
action makes alternative testing methods available for particular
drinking water contaminants beyond the testing methods currently
established in the regulations. EPA is providing public water systems
required to test water samples with a choice of using either a test
procedure already established in the existing regulations or an
alternative test procedure that has been approved in this action or in
prior expedited approval actions. Categories and entities that may
ultimately be affected by this action include:
----------------------------------------------------------------------------------------------------------------

II. Background
A. What is the purpose of this action?
In this action, EPA is approving 11 analytical methods for
determining contaminant concentrations in samples collected under SDWA.
Regulated parties required to sample and monitor may use either the
testing methods already established in existing regulations or the
alternative testing methods being approved in this action or in prior
expedited approval actions. The new methods are listed in Appendix A to
Subpart C of Part 141 and on EPA's drinking water methods Web site at
http://water.epa.gov/scitech/drinkingwater/labcert/analyticalmethods_expedited.cfm.
This action also corrects the entry for dalapon in Appendix A to
Subpart C of Part 141. In an earlier expedited methods approval action,
Standard Methods 6640 B and 6640 B-01 were incorrectly listed under the
same analytical methodology as EPA Method 557 for the determination of
dalapon in drinking water. This action amends the dalapon entry to
specify the appropriate methodology for each of these methods.
This action also revised entries in Appendix A to Subpart C of Part
141 for arsenic, barium, beryllium, cadmium, calcium, chromium, copper,
lead, magnesium, nickel, selenium, silica, sodium, iron, manganese, and
silver to include the footnote citation for EPA Method 200.5, Revision
4.2.
B. What is the basis for this action?
When EPA determines that an alternative analytical method is
``equally effective'' (i.e., as effective as a method that has already
been promulgated in the regulations), SDWA allows EPA to approve the
use of the alternative method through publication in the Federal
Register. (See Section 1401(1) of SDWA.) EPA is using this streamlined
approval authority to make 11 additional methods available for
determining contaminant concentrations in samples collected under SDWA.
EPA has determined that, for each contaminant or group of contaminants
listed in Section III, the additional testing methods being approved in
this action are as effective as one or more of the testing methods
already approved in the regulations for those contaminants. Section
1401(1) of SDWA states that the newly approved methods ``shall be
treated as an alternative for public water systems to the quality
control and testing procedures listed in the regulation.'' Accordingly,
this action makes these additional (and optional) 11 analytical methods
legally available for meeting EPA's monitoring requirements.
This action does not add regulatory language, but does, for
informational purposes, update an appendix to the regulations at 40 CFR
Part 141 that lists all methods approved under Section 1401(1) of SDWA.
Accordingly, while this action is not a rule, it is updating CFR text
and therefore is being published in the ``Final Rules'' section of the
Federal Register.
III. Summary of Approvals
EPA is approving 11 methods that are equally effective relative to
methods previously promulgated in the regulations. By means of this
notice, these 11 methods are added to Appendix A to Subpart C of 40 CFR
Part 141.
A. Methods Developed by Voluntary Consensus Standard Bodies (VCSB)
1. Standard Methods for the Examination of Water and Wastewater
(Standard Methods). EPA compared the most recent versions of four
Standard Methods to earlier versions of those methods that are
currently approved in 40 CFR 141 and 143. Changes between the earlier
approved version and the most recent version of each method are
summarized in Smith (2011). The revisions primarily involve editorial
changes (i.e., corrections of errors, procedural clarifications, and
reorganization of text). The revised methods are the same as the
earlier approved versions with respect to the chemistry, sample
handling protocols, and method performance data. The new versions are
thus equally effective relative to those that are currently approved in
the regulations. Therefore, EPA is approving the use of the four
updated Standard Methods for the contaminants and their respective
regulations listed in the following table:
----------------------------------------------------------------------------------------------------------------

Two additional Standard Methods, 6640 B, published in the 21st
edition (APHA 2005), and its identical online version, 6640 B-01 (APHA
2001), were approved in a previous expedited methods approval action
for determining dalapon in drinking water (75 FR 32295, June 8, 2010)
(USEPA 2010). Standard Method 6640 B was developed directly from EPA
Method 515.4 (USEPA 2000), and thus entails the identical sample
collection/handling protocols, sample preparation and derivatization
steps, chromatographic conditions, and detection. The method
performance data (e.g., detection levels, accuracy and precision)
specified in Standard Method 6640 B and EPA Method 515.4 are identical.
In addition to addressing dalapon, EPA Method 515.4 is also an approved
method for analyzing drinking water compliance samples for 2,4-D,
2,4,5-TP (i.e., Silvex), dinoseb, pentachlorophenol, and picloram as
cited at 40 CFR 141.24(e)(1). Therefore, in this action EPA is
expanding approval of Standard Method 6640 B and Standard Method 6640
B-01 for determining 2,4-D, 2,4,5-TP (i.e., Silvex), dinoseb,
pentachlorophenol, and picloram in drinking water. The 21st edition can
be obtained from the American Public Health Association (APHA), 800 I
Street, NW., Washington, DC 20001-3710. Online versions of Standard
Methods are available at http://www.standardmethods.org.
2. ASTM International. EPA compared the most recent versions of
three ASTM International methods to the earlier versions of those
methods that are currently approved in 40 CFR 141. Changes between the
earlier approved version and the most recent version of each method are
summarized in Smith (2011). The revisions primarily involve editorial
changes (i.e., updated references, definitions, terminology, and
reorganization of text). The revised methods are the same as the
approved versions with respect to sample collection and handling
protocols, sample preparation, analytical methodology, and method
performance data. In addition, the revised version of the ASTM method
for the radiochemical determination of uranium (ASTM Method D3972-09)
expands the QC requirements beyond those required in the previous
version. EPA has thus determined that the new versions are equally
effective relative to those currently in the regulations. Therefore,
EPA is approving the use of the three updated ASTM methods for the
contaminants and their respective regulations listed in the following
table:
----------------------------------------------------------------------------------------------------------------

The ASTM methods are available from ASTM International, 100 Barr
Harbor Drive, West Conshohocken, PA 19428-2959 or http://www.astm.org.
B. Methods Developed by Vendors
1. Hach Company TNTplusTM 835/836 Nitrate Method 10206
(Hach Company 2011a). The Hach Company TNTplus 835/836 nitrate method
10206 uses spectrophotometric analysis to determine nitrate
concentrations in drinking water. The method involves the following
steps:
Electrophilic substitution of the dimethylphenol reagent
results in a colored nitro-dimethylphenol product, and
Colorimetric measurement of the absorbance at 345 nm is
directly proportional to the concentration of the nitrate in the
sample.
The currently approved methods for nitrate are listed at 40 CFR
141.23(k)(1). An inter-laboratory study was conducted by the vendor to
compare the method performance of the Hach Company TNTplus 835/836
nitrate method 10206 to the performance of three approved methods: EPA
Method 353.2 (USEPA 1993a), EPA Method 300.0 (USEPA 1993b), and
Standard Method 4500-NO3- E (APHA 1998). Three
laboratories analyzed a variety of matrices (e.g., low ionic strength,
high ionic strength, and drinking water samples derived from both
surface water and ground water sources). The samples were analyzed for
nitrate by running approved methods alongside the Hach Company TNTplus
835/836 nitrate method 10206. EPA has determined that the Hach Company
TNTplus 835/836 nitrate method 10206 is as effective as EPA Method
353.2, EPA Method 300.0, and Standard Method 4500-
NO3- E. The basis for this determination is
discussed in the validation study report (Hach Company 2010a) which
summarizes the results obtained from the inter-laboratory study. The
method is also a ``green'' alternative to approved nitrate methods that
use the toxic metal, cadmium. Therefore, EPA is approving the Hach
Company TNTplus 835/836 nitrate method 10206 for determining nitrate
concentrations in drinking water. The Hach Company TNTplus 835/836
nitrate method 10206 can be obtained from Hach Company, 5600 Lindbergh
Drive, P.O. Box 389, Loveland, Colorado 80539, phone: (970) 669-3050.
2. Hach Company SPADNS 2 (Arsenic-free) Fluoride Method 10225 (Hach
Company 2011b). The Hach Company SPADNS 2 (Arsenic-free) Fluoride
Method 10225 uses spectrophotometric analysis to determine fluoride
concentrations in drinking water. The currently approved method using
SPADNS chemistry for determining fluoride concentrations, Standard
Method 4500-F- D (APHA 1998), is listed at 40 CFR
141.23(k)(1). As described in the approved method,
[[Page 37017]]
the presence of residual chlorine in water is a known interferent and
the method specifies addition of sodium arsenite to quench the
chlorine. The Hach Company SPADNS 2 (Arsenic-free) Fluoride Method
10225 replaces sodium arsenite with a proprietary non-toxic, non-
hazardous chlorine scavenger. An inter-laboratory study was conducted
by the vendor to compare the method performance of the Hach Company
SPADNS 2 (Arsenic-free) Fluoride method 10225 to the performance of the
approved SPADNS method. Three laboratories analyzed a variety of
matrices (e.g., low ionic strength, high ionic strength, distilled and
undistilled chlorinated drinking water samples derived from both
surface water and ground water sources). The samples were analyzed for
fluoride by running the approved method alongside the Hach Company
SPADNS 2 (Arsenic-free) Fluoride Method 10225. EPA has determined that
the Hach Company SPADNS 2 (Arsenic-free) Fluoride Method 10225 is as
effective as Standard Method 4500-F- D. The basis for this
determination is discussed in the validation study report (Hach Company
2010b) which summarizes the results obtained from the inter-laboratory
study. Therefore, EPA is approving the Hach Company SPADNS 2 (Arsenic-
free) Fluoride Method 10225 for determining fluoride concentrations in
drinking water. The Hach Company SPADNS (Arsenic-free) Fluoride Method
10225 can be obtained from Hach Company, 5600 Lindbergh Drive, P.O. Box
389, Loveland, Colorado 80539, phone: (800) 227-4224.
IV. Statutory and Executive Order Reviews
As noted in Section II, under the terms of SDWA Section 1401(1),
this streamlined method approval action is not a rule. Accordingly, the
Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement Fairness Act of 1996, does not apply
because this action is not a rule for purposes of 5 U.S.C. 804(3).
Similarly, this action is not subject to the Regulatory Flexibility Act
because it is not subject to notice and comment requirements under the
Administrative Procedure Act or any other statute. In addition, because
this approval action is not a rule but simply makes alternative
(optional) testing methods available for monitoring under SDWA, EPA has
concluded that other statutes and executive orders generally applicable
to rulemaking do not apply to this approval action.
