32558 Federal Register / Vol. 78, No. 105 / Friday, May 31, 2013 / Rules and Regulations 

determined that this rule does not have 

implications for federalism. 

6. 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. 

10. Protection of Children 

We have analyzed this rule under 

Executive Order 13045, Protection of 

Children from Environmental Health 

Risks and Safety Risks. This rule is not 

an economically significant rule and 

does not create an environmental risk to 

health or risk to safety that may 

disproportionately affect children. 

11. Indian Tribal Governments 

This rule does not have tribal 

implications under Executive Order 

13175, Consultation and Coordination 

with Indian Tribal Governments, 

because it does not have a substantial 

direct effect on one or more Indian 

tribes, on the relationship between the 

Federal Government and Indian tribes, 

or on the distribution of power and 

responsibilities between the Federal 

Government and Indian tribes. 

12. Energy Effects 

This action is not a ‘‘significant 

energy action’’ under Executive Order 

13211, Actions Concerning Regulations 

That Significantly Affect Energy Supply, 

Distribution, or Use. 

13. Technical Standards 

This rule does not use technical 

standards. Therefore, we did not 

consider the use of voluntary consensus 

standards. 

14. Environment 

We have analyzed this rule under 

Department of Homeland Security 

Management Directive 023–01 and 

Commandant Instruction M16475.lD, 

which guide the Coast Guard in 

complying with the National 

Environmental Policy Act of 1969 

(NEPA) (42 U.S.C. 4321–4370f), and 

have determined that this action is one 

of a category of actions that do not 

individually or cumulatively have a 

significant effect on the human 

environment. This rule involves the 

establishment of a safety zone on the 

navigable waters of the Atlantic Ocean 

in Ocean City, MD in order to restrict 

vessel traffic movement to protect 

mariners from the hazards associated 

with air show events. This rule is 

categorically excluded from further 

review under paragraph 34(g) of Figure 

2–1 of the Commandant Instruction. An 

environmental analysis checklist 

supporting this determination and a 

Categorical Exclusion Determination 

will be available in the docket where 

indicated under ADDRESSES.

Federal Register / Vol. 78, No. 105 / Friday, May 31, 2013 / Rules and Regulations 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.

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: 

Category Examples of potentially regulated entities NAICS1

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

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 http://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 


tkelley on DSK3SPTVN1PROD with RULES
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 

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; transdichloroethylene; 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 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. 

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.

accessed and downloaded directly online at http://water.epa.gov/scitech/

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 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 78, No. 105 / Friday, May 31, 2013 / Rules and Regulations 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 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 

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.
