Protest Activities The Coast Guard respects the First Amendment rights of protesters. Protesters are asked to contact the person listed in the FOR FURTHER INFORMATION CONTACT section to coordinate protest activities so that your message can be received without jeopardizing the safety or security of people, places or vessels. 7. Unfunded Mandates Reform Act The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531–1538) requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 (adjusted for inflation) or more in any one year. Though this rule will not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble. 8. Taking of Private Property This rule will not cause a taking of private property or otherwise have taking implications under Executive Order 12630, Governmental Actions and Interference with Constitutionally Protected Property Rights. 9. Civil Justice Reform This rule meets applicable standards in sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, eliminate ambiguity, and reduce burden. tkelley on DSK3SPTVN1PROD with RULES 10.

ACTION: Final rule. AGENCY: SUMMARY: This action announces the U.S. Environmental Protection Agency’s E:\FR\FM\31MYR1.SGM 31MYR1 Federal Register / Vol. 78, No. 105 / Friday, May 31, 2013 / Rules and Regulations (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 84 additional methods available for analyzing drinking water samples. 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.

SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: 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: Category Examples of potentially regulated entities State, Local, & Tribal Governments ............... States, local and Tribal governments that analyze water samples on behalf of public water systems required to conduct such analysis; States, local and Tribal governments that themselves operate community and non-transient non-community water systems required to monitor. Private operators of community and non-transient non-community water systems required to monitor. Municipal operators of community and non-transient non-community water systems required to monitor.

Background A. What is the purpose of this action? In this action, EPA is approving 84 analytical methods for determining contaminant concentrations in samples PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 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 along with other previously expedited methods in 40 CFR Part 141 Appendix A to Subpart C and on EPA’s drinking water methods Web site at https://water.epa.gov/scitech/ drinkingwater/labcert/ analyticalmethods_expedited.cfm. 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 84 additional methods available for determining contaminant concentrations in samples collected under the SDWA. EPA has determined that, for each contaminant or group of contaminants listed in Section III, the additional testing methods being E:\FR\FM\31MYR1.SGM 31MYR1 32560 Federal Register / Vol. 78, No. 105 / Friday, May 31, 2013 / Rules and Regulations 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 84 analytical methods legally available as options 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 84 methods that are equally effective relative to methods previously promulgated in the regulations. By means of this notice, these 84 methods are added to Appendix A to Subpart C of 40 CFR Part 141. A. Methods Developed by EPA 1. EPA Method 524.4 (USEPA 2013) is a gas chromatography/mass spectrometry (GC/MS) method for the determination of 21 purgeable organic compounds, which are regulated in drinking water as specified at 40 CFR 141.61(a)(1) through (21), and total trihalomethanes (TTHM), which are regulated in drinking water as specified at 40 CFR 141.64(b)(1) and (2). The method analytes are purged from the water sample using nitrogen and trapped on a sorbent material. After purging, the sorbent trap is heated and back flushed with GC carrier gas and the analytes are transferred to a capillary GC column. The analytes eluting from the GC column are directed into a mass spectrometer for detection and quantitation. The analytes are identified by comparing the acquired mass spectra Standard method, 22nd edition (APHA 2012) 2120 B .......................... tkelley on DSK3SPTVN1PROD with RULES 2130 B .......................... 2150 B .......................... 2320 B .......................... 2510 B .......................... VerDate Mar<15>2010 and retention times for calibration standards acquired under identical GC/ MS conditions. The concentration of each analyte is calculated using the internal standard technique and response curves are generated using procedural calibration standards. EPA Method 524.4 is an extension of EPA Method 524.3 (USEPA 2009a) which was approved in an earlier expedited methods approval action (74 FR 38348, August 3, 2009) (USEPA 2009b). Both EPA Methods 524.4 and 524.3 are updated versions of EPA Method 524.2, Revision 4.1 (USEPA 1995), which is currently approved at 40 CFR 141.24(e)(1) for the analysis of benzene; carbon tetrachloride; chlorobenzene; 1,2-dichlorobenzene; 1,4dichlorobenzene; 1,2-dichloroethane; cis-dichloroethylene; transdichloroethylene; dichloromethane; 1,2dichloropropane; ethylbenzene; styrene; tetrachloroethylene; 1,1,1trichloroethane; trichloroethylene; toluene; 1,2,4-trichlorobenzene; 1,1dichloroethylene; 1,1,2-trichloroethane; vinyl chloride; total xylenes (sum of oxylene, m-xylene, and p-xylene) and total trihalomethanes (TTHM; sum of chloroform, bromodichloromethane, dibromochloromethane, and bromoform). EPA Method 524.2, Revision 4.1 is also approved at 40 CFR 141.131(b)(1) for TTHM. The primary difference between EPA Method 524.4 and EPA Method 524.3 lies in the purge gas. The cost of helium continues to rise and EPA Method 524.4 was developed using less expensive nitrogen gas to purge the analytes from drinking water samples instead of helium. For each of the purgeable organic compounds and TTHM contaminants, the method performance characteristics of EPA Method 524.4 were compared to those of the approved method, EPA Method 524.2, Revision 4.1. EPA has determined EPA Method 524.4 is equally as effective as the approved method for determining the concentrations of each of the regulated purgeable organic compounds and TTHM contaminants in drinking water.

Therefore, EPA is approving the use of EPA Method 524.4 for each of the above named contaminants when analyzing drinking water compliance samples. A copy of EPA Method 524.4 can be accessed and downloaded directly online at https://water.epa.gov/scitech/ drinkingwater/labcert/ analyticalmethods.cfm. B. Methods Developed by Voluntary Consensus Standard Bodies (VCSB) 1. Standard Methods for the Examination of Water and Wastewater (Standard Methods). The 22nd edition of Standard Methods for the Examination of Water and Wastewater (APHA 2012) was published earlier this year. EPA compared 79 methods in the 22nd edition to earlier versions of those methods that are currently approved in 40 CFR Part 141. Changes between the approved version and the version of each method published in the 22nd edition are summarized in Smith and Wendelken (2012b) and Best (2013). The revisions primarily involve editorial changes (e.g., corrections of errors, procedural clarifications, and reorganization of text); in addition, most of the chemistry methods in the 22nd edition contain an editorial change that directs analysts to the appropriate Quality Control (QC) section that contains the QC criteria and practices that are to be followed as part of the method. The methods in the 22nd edition listed in the following table are the same as the earlier approved versions with respect to the chemistry, sample handling protocols, and method performance data. For all of these reasons, EPA has concluded that the versions in the 22nd edition are thus equally effective relative to those that are currently approved in the regulations. Therefore, EPA is approving the use of 79 updated Standard Methods in the 22nd edition for the contaminants and their respective regulations listed in the following table: Contaminant Regulation online version (APHA Color ................................................... 40 CFR 143.4(b) online version (APHA Turbidity .............................................. 40 CFR 141.74(a)(1) online version (APHA Odor .................................................... 40 CFR 143.4(b) online version (APHA Alkalinity ............................................. 40 CFR 141.23(k)(1) online version (APHA Conductivity ........................................ 40 CFR 141.23(k)(1) Jkt 229001 PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 E:\FR\FM\31MYR1.SGM 31MYR1 Federal Register / Vol. 78, No. 105 / Friday, May 31, 2013 / Rules and Regulations 32561 Standard method, 22nd edition (APHA 2012) Approved method Contaminant 2540 C .......................... 2540 C–97, online version (APHA 1997d). 2550–00, online version (APHA 2000a). 3111 B–99, online version (APHA 1999a).

EPA compared the most recent versions of three ASTM International methods (ASTM Methods D516–11, D1067–11 B, Regulation and D1293–12) to the earlier versions of those methods that are currently approved in 40 CFR part 141. Changes between the earlier approved version and the most recent version of each method are summarized in Smith (2012). The revisions primarily involve editorial changes (e.g., updated references, definitions, terminology, and reorganization of text). The revised methods are the same as the approved 40 CFR 141.25(a) versions with respect to sample collection and handling protocols, sample preparation, analytical methodology, and method performance data, and thus, EPA finds they are equally effective relative to the approved methods. EPA is thus approving the use of the following ASTM methods for the contaminants and their respective regulations listed in the following table: Approved method Contaminant D516–11 (ASTM 2011a) ................................. D1067–11 B (ASTM 2011b) ............................

Fast Phage (2012a) is a microbiological method for the detection of male-specific (F+) and VerDate Mar<15>2010 16:51 May 30, 2013 Jkt 229001 somatic coliphages in ground water by a two-step enrichment procedure. Coliphages are detected as being present or absent in 100 mL samples of ground water by the formation of plaques on agar plates containing the host bacterium. Fast Phage includes a presumptive rapid fluorescence step PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 Regulation 40 CFR 143.4(b) 40 CFR 141.23(k)(1) 40 CFR 141.23(k)(1) that can predict coliphage positive samples in less than eight hours. EPA Method 1601 (USEPA 2001b) is currently approved under the Ground Water Rule (GWR) at 40 CFR 141.402(c)(2) for the detection of coliphages in ground water source waters. Fast Phage is similar to EPA Method 1601 but has modifications to E:\FR\FM\31MYR1.SGM 31MYR1 Federal Register / Vol. 78, No. 105 / Friday, May 31, 2013 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES the medium and incubation temperature, which make the method more rapid. Fast Phage is able to detect coliphages in 16 to 30 hours compared to 40 to 60 hours for EPA Method 1601. Additionally, Fast Phage includes kits, which supply the medium, antibiotics and freeze-dried host bacteria in a prepackaged and standardized form for easier use. A multi-laboratory study was conducted to compare the method performance of Fast Phage to the performance of the approved method, EPA Method 1601. Three geographically diverse wastewaters were used as sources of somatic and male-specific coliphages for the study. In four different laboratories, Fast Phage was compared side by side with EPA Method 1601 for somatic and malespecific coliphage detection in local ground waters that were inoculated with low level coliphages from each of the test wastewaters. Ten replicates of inoculated ground waters were evaluated for both Fast Phage and EPA Method 1601, and each test wastewater was evaluated as an inoculant. The study report (Charm Sciences Inc. 2012b) details the study design and implementation along with the validation data obtained from the multilaboratory evaluation. The results of the multi-laboratory studies indicate that Fast Phage is equally as effective as EPA Method 1601 in method performance for detecting male-specific and somatic coliphages in ground water. The basis for this determination is discussed in Sinclair (2013). EPA is thus approving Fast Phage as an alternate method to EPA Method 1601 for the detection of male-specific and somatic coliphages in ground water under the Ground Water Rule. The Fast Phage method is available from Charm Sciences, Inc., 659 Andover Street, Lawrence, MA 01843, and also at www.charmsciences.com. 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 VerDate Mar<15>2010 16:51 May 30, 2013 Jkt 229001 makes alternative testing methods available as options for monitoring under SDWA, EPA has concluded that other statutes and executive orders generally applicable to rulemaking do not apply to this approval action.

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 U.S. Environmental Protection 
Agency's

[[Page 32559]]

(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 84 additional methods 
available for analyzing drinking water samples. 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 May 31, 2013.

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 84 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 along with other 
previously expedited methods in 40 CFR Part 141 Appendix A to Subpart C 
and on EPA's drinking water methods Web site at https://water.epa.gov/scitech/drinkingwater/labcert/analyticalmethods_expedited.cfm.

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 84 additional methods available for 
determining contaminant concentrations in samples collected under the 
SDWA. EPA has determined that, for each contaminant or group of 
contaminants listed in Section III, the additional testing methods 
being

[[Page 32560]]

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 84 analytical methods legally 
available as options 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 84 methods that are equally effective relative to 
methods previously promulgated in the regulations. By means of this 
notice, these 84 methods are added to Appendix A to Subpart C of 40 CFR 
Part 141.

A. Methods Developed by EPA

    1. EPA Method 524.4 (USEPA 2013) is a gas chromatography/mass 
spectrometry (GC/MS) method for the determination of 21 purgeable 
organic compounds, which are regulated in drinking water as specified 
at 40 CFR 141.61(a)(1) through (21), and total trihalomethanes (TTHM), 
which are regulated in drinking water as specified at 40 CFR 
141.64(b)(1) and (2). The method analytes are purged from the water 
sample using nitrogen and trapped on a sorbent material. After purging, 
the sorbent trap is heated and back flushed with GC carrier gas and the 
analytes are transferred to a capillary GC column. The analytes eluting 
from the GC column are directed into a mass spectrometer for detection 
and quantitation. The analytes are identified by comparing the acquired 
mass spectra and retention times for calibration standards acquired 
under identical GC/MS conditions. The concentration of each analyte is 
calculated using the internal standard technique and response curves 
are generated using procedural calibration standards. EPA Method 524.4 
is an extension of EPA Method 524.3 (USEPA 2009a) which was approved in 
an earlier expedited methods approval action (74 FR 38348, August 3, 
2009) (USEPA 2009b). Both EPA Methods 524.4 and 524.3 are updated 
versions of EPA Method 524.2, Revision 4.1 (USEPA 1995), which is 
currently approved at 40 CFR 141.24(e)(1) for the analysis of benzene; 
carbon tetrachloride; chlorobenzene; 1,2-dichlorobenzene; 1,4-
dichlorobenzene; 1,2-dichloroethane; cis-dichloroethylene; trans-
dichloroethylene; dichloromethane; 1,2-dichloropropane; ethylbenzene; 
styrene; tetrachloroethylene; 1,1,1-trichloroethane; trichloroethylene; 
toluene; 1,2,4-trichlorobenzene; 1,1-dichloroethylene; 1,1,2-
trichloroethane; vinyl chloride; total xylenes (sum of o-xylene, m-
xylene, and p-xylene) and total trihalomethanes (TTHM; sum of 
chloroform, bromodichloromethane, dibromochloromethane, and bromoform). 
EPA Method 524.2, Revision 4.1 is also approved at 40 CFR 141.131(b)(1) 
for TTHM. The primary difference between EPA Method 524.4 and EPA 
Method 524.3 lies in the purge gas. The cost of helium continues to 
rise and EPA Method 524.4 was developed using less expensive nitrogen 
gas to purge the analytes from drinking water samples instead of 
helium.
    For each of the purgeable organic compounds and TTHM contaminants, 
the method performance characteristics of EPA Method 524.4 were 
compared to those of the approved method, EPA Method 524.2, Revision 
4.1. EPA has determined EPA Method 524.4 is equally as effective as the 
approved method for determining the concentrations of each of the 
regulated purgeable organic compounds and TTHM contaminants in drinking 
water. The basis for this determination is discussed in detail in Smith 
and Wendelken (2012a). Therefore, EPA is approving the use of EPA 
Method 524.4 for each of the above named contaminants when analyzing 
drinking water compliance samples.

on-line at https://water.epa.gov/scitech/drinkingwater/labcert/analyticalmethods.cfm.

B. Methods Developed by Voluntary Consensus Standard Bodies (VCSB)

    1. Standard Methods for the Examination of Water and Wastewater 
(Standard Methods). The 22nd edition of Standard Methods for the 
Examination of Water and Wastewater (APHA 2012) was published earlier 
this year. EPA compared 79 methods in the 22nd edition to earlier 
versions of those methods that are currently approved in 40 CFR Part 
141. Changes between the approved version and the version of each 
method published in the 22nd edition are summarized in Smith and 
Wendelken (2012b) and Best (2013). The revisions primarily involve 
editorial changes (e.g., corrections of errors, procedural 
clarifications, and reorganization of text); in addition, most of the 
chemistry methods in the 22nd edition contain an editorial change that 
directs analysts to the appropriate Quality Control (QC) section that 
contains the QC criteria and practices that are to be followed as part 
of the method. The methods in the 22nd edition listed in the following 
table are the same as the earlier approved versions with respect to the 
chemistry, sample handling protocols, and method performance data. For 
all of these reasons, EPA has concluded that the versions in the 22nd 
edition are thus equally effective relative to those that are currently 
approved in the regulations. Therefore, EPA is approving the use of 79 
updated Standard Methods in the 22nd edition for the contaminants and 
their respective regulations listed in the following table:

    2. ASTM International. EPA compared the most recent versions of 
three ASTM International methods (ASTM Methods D516-11, D1067-11 B, and 
D1293-12) to the earlier versions of those methods that are currently 
approved in 40 CFR part 141. Changes between the earlier approved 
version and the most recent version of each method are summarized in 
Smith (2012). The revisions primarily involve editorial changes (e.g., 
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, and 
thus, EPA finds they are equally effective relative to the approved 
methods.
    EPA is thus approving the use of the following ASTM methods for the 
contaminants and their respective regulations listed in the following 
table:

C. Methods Developed by Vendors

    1. Charm Sciences, Inc. Fast Phage (2012a) is a microbiological 
method for the detection of male-specific (F+) and somatic coliphages 
in ground water by a two-step enrichment procedure. Coliphages are 
detected as being present or absent in 100 mL samples of ground water 
by the formation of plaques on agar plates containing the host 
bacterium. Fast Phage includes a presumptive rapid fluorescence step 
that can predict coliphage positive samples in less than eight hours.
    EPA Method 1601 (USEPA 2001b) is currently approved under the 
Ground Water Rule (GWR) at 40 CFR 141.402(c)(2) for the detection of 
coliphages in ground water source waters. Fast Phage is similar to EPA 
Method 1601 but has modifications to

[[Page 32563]]

the medium and incubation temperature, which make the method more 
rapid. Fast Phage is able to detect coliphages in 16 to 30 hours 
compared to 40 to 60 hours for EPA Method 1601. Additionally, Fast 
Phage includes kits, which supply the medium, antibiotics and freeze-
dried host bacteria in a pre-packaged and standardized form for easier 
use.
    A multi-laboratory study was conducted to compare the method 
performance of Fast Phage to the performance of the approved method, 
EPA Method 1601. Three geographically diverse wastewaters were used as 
sources of somatic and male-specific coliphages for the study. In four 
different laboratories, Fast Phage was compared side by side with EPA 
Method 1601 for somatic and male-specific coliphage detection in local 
ground waters that were inoculated with low level coliphages from each 
of the test wastewaters. Ten replicates of inoculated ground waters 
were evaluated for both Fast Phage and EPA Method 1601, and each test 
wastewater was evaluated as an inoculant. The study report (Charm 
Sciences Inc. 2012b) details the study design and implementation along 
with the validation data obtained from the multi-laboratory evaluation. 
The results of the multi-laboratory studies indicate that Fast Phage is 
equally as effective as EPA Method 1601 in method performance for 
detecting male-specific and somatic coliphages in ground water. The 
basis for this determination is discussed in Sinclair (2013). EPA is 
thus approving Fast Phage as an alternate method to EPA Method 1601 for 
the detection of male-specific and somatic coliphages in ground water 
under the Ground Water Rule.
    The Fast Phage method is available from Charm Sciences, Inc., 659 
Andover Street, Lawrence, MA 01843, and also at www.charmsciences.com.

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 testing 
methods available as options for monitoring under SDWA, EPA has 
concluded that other statutes and executive orders generally applicable 
to rulemaking do not apply to this approval action.
