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.

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: 

ASTM revised version ASTM approved version Contaminant Regulation

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, 


jlentini on DSK4TPTVN1PROD with RULES
Federal Register / Vol. 76, No. 122 / Friday, June 24, 2011 / Rules and Regulations 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 (Arsenicfree) Fluoride Method 10225 replaces 

sodium arsenite with a proprietary nontoxic, non-hazardous chlorine 

scavenger. An inter-laboratory study 

was conducted by the vendor to 

compare the method performance of the 

Hach Company SPADNS 2 (Arsenicfree) 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 (Arsenicfree) 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 interlaboratory 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.

Louisiana: Final Authorization of State 

Hazardous Waste Management 

Program Revision 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Immediate final rule. 

SUMMARY: Louisiana has applied to the 

EPA for final authorization of the 

changes to its hazardous waste program 

under the Resource Conservation and 

Recovery Act (RCRA). The EPA has 

determined that these changes satisfy all 

requirements needed to qualify for final 

authorization, and is authorizing the 

State’s changes through this immediate 

final action. The EPA is publishing this 

rule to authorize the changes without a 

prior proposal because we believe this 

action is not controversial and do not 

expect comments that oppose it. Unless 

we receive written comments which 

oppose this authorization during the 

comment period, the decision to 

authorize Louisiana’s changes to its 

hazardous waste program will take 

effect. If we receive comments that 

oppose this action, we will publish a 

document in the Federal Register 

withdrawing this rule before it takes 

effect, and a separate document in the 

proposed rules section of this Federal 

Register will serve as a proposal to 

authorize the changes. 

DATES: This final authorization will 

become effective on August 23, 2011 

unless the EPA receives adverse written 

comment by July 25, 2011. If the EPA 

receives such comment, it will publish 

a timely withdrawal of this immediate 

final rule in the Federal Register and 

inform the public that this authorization 

will not take effect. 

ADDRESSES: Submit your comments by 

one of the following methods: 

1. Federal eRulemaking Portal: 

http://www.regulations.gov. Follow the 

on-line instructions for submitting 

comments. 

2. E-mail: patterson.alima@epa.gov.
