Procedures 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This action announces the 

U.S. 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 21 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 June 19, 

2014.

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 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 21 

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 methods similarly approved 

through previous expedited actions 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 

21 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 21 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 21 methods that are 

equally effective relative to methods 

previously promulgated in the 

regulations. By means of this rule, these 

21 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 online versions of 14 

Standard Methods to earlier versions of 

those methods that are currently 

approved in 40 CFR parts 141 and 143. 

Changes between the approved version 

and the most recent version of each 

method are summarized in Smith and 

Wendelken (2013a). The revisions 

primarily involve editorial changes (e.g., 

corrections of errors, procedural 

clarifications, and reorganization of 

text). The updated online versions listed 

in the following table are the same as 

the earlier approved versions with 

respect to the chemistry and 

microbiology, sample handling 

protocols, and method performance 

data. For all of these reasons, EPA has 

concluded that the updated online 

versions are equally effective relative to 

those that are currently approved in the 

regulations. Therefore, EPA is approving 

the use of the 14 updated Standard 

Methods for the contaminants and their 

respective regulations listed in the 

following table:

The 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 

(ASTM Methods D512–12 B, D3223–12, 

and D4327–11) to the 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 

(2013). The revisions primarily involve 

editorial changes (e.g., updated 

references, definitions, terminology, 

procedural clarifications, 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; 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: 

ASTM Revised version Approved method Contaminant Regulation

B. Methods Developed by Vendors 

1. IDEXX Laboratories, Inc. Colilert18®. Colilert-18® is an approved 

commercial medium capable of 

simultaneous detection of total coliform 

and Escherichia coli bacteria. The use of 

this medium is described in Standard 

Method 9223 B, 21st edition of 

Standard Methods for the Examination 

of Water and Wastewater (APHA 

2005b). Standard Method 9223 B is 

approved for determination of total 

coliform bacteria and E. coli under the 

Revisions to the Total Coliform Rule 

(RTCR) (USEPA 2013) as cited at 40 CFR 

141.852(a)(5). Colilert-18® is a minor 

variation of an already approved 

medium, and was determined to be 

applicable to the Total Coliform Rule 

(TCR) (Dougherty 1996). EPA is using 

today’s action to clarify that Colilert-18®

is itself an approved medium when 

used as described in Standard Method 

9223 B for determining total coliform 

bacteria and E. coli in drinking water 

under the RTCR. Accordingly, EPA is 

adding the Colilert-18® medium and 

methodology as described in Standard 

Method 9223 B to the list of alternative 

testing methods in Appendix A to 

Subpart C of Part 141. Colilert-18® is

2. Hach Company Method 10260— 

Determination of Chlorinated Oxidants 

(Free and Total) in Water using 

Disposable Planar Reagent-Filled 

Cuvettes and Mesofluidic Channel 

Colorimetry (Hach Company 2013a). 

The Hach Company Method 10260 uses 

disposable planar reagent-filled cuvettes 

(PRFC) to measure free, total and 

combined chlorine as an optional 

alternate test procedure to Standard 

Method 4500–Cl G (APHA 1998) which 

is approved in the drinking water 

regulations at 40 CFR 141.74(a)(2) for 

determination of free and total chlorine, 

and at 40 CFR 141.131(c)(1) for 

determination of free, total and 

combined chlorine. In this method, a 

mesofluidic pump system draws a water 

sample through a cuvette that is 

prefilled with the reagents required to 

perform DPD (N,N-diethyl-pphenylenediamine) colorimetric 

chlorine tests. The sample is then drawn 

to an optical channel where the chlorine 

level is measured at a wavelength 

between 490 and 530 nm. Automation 

of the DPD determination relative to the 

manual procedure described in the 

approved method reduces errors 

associated with reagent addition, mixing 

and color development. Three 

laboratories analyzed a variety of 

drinking water matrices (e.g., low ionic 

strength, high ionic strength, and tap 

water samples derived from both surface 

water and ground water sources). The 

performance characteristics of the Hach 

Method 10260 were compared to the 

performance characteristics of the 

approved method. The validation study 

report (Hach 2013b) summarizes the 

results obtained from the multilaboratory study and indicates that Hach 

Method 10260 is equally as effective as 

Standard Method 4500–Cl G for the 

colorimetric determination of free and 

total chlorine in drinking water. The 

basis for this determination is discussed 

in Smith and Wendelken (2013b). EPA 

is thus approving Hach Method 10260 

as an alternate method to Standard 

Method 4500–Cl G for the analysis of 

free and total chlorine in drinking 

water. Hach Method 10260 is available 

from Hach Company, 5600 Lindbergh 

Drive, P.O. Box 389, Loveland, CO 

80539, and also at www.hach.com. 

3. Palintest Ltd ChlordioX Plus 

Method—Chlorine Dioxide and Chlorite 

in Drinking Water by Amperometry 

using Disposable Sensors (Palintest Ltd 

2013). The Palintest Ltd ChlordioX Plus 

uses recyclable disposable sensors for 

amperometric detection of chlorine 

dioxide and the disinfection byproduct, 

chlorite, in drinking water. Standard 

Method 4500–ClO2 E (APHA 1998) is an 

amperometric titration method that is 

currently approved in the regulations at 

40 CFR 141.74(a)(2) and 40 CFR 

141.131(c)(1) for determination of 

chlorine dioxide in drinking water; it is 

also cited in the regulations at 40 CFR 

141.131(b)(1) for routine daily 

monitoring of chlorite. The approved 

method requires experienced analysts 

and is not portable, which limits 

options for field and site testing. The 

ChlordioX Plus method is associated 

with a portable sensor driven 

instrument and chlorine dioxide 

standards are available, which can be 

used with the instrument. Chlorine 

dioxide is reduced at the surface of the 

sensor and the current produced is 

directly proportional to the chlorine 

dioxide level in the sample. The chlorite 

level can be determined from a sample 

duplicate by oxidation of iodide to 

iodine. The method performance of the 

ChlordioX Plus method was compared 

to the performance of Standard Method 

4500–ClO2 E at three public drinking 

water utilities that use chlorine dioxide 

for primary disinfection. A variety of 

samples, including drinking water 

samples from both surface and ground 

water sources, were fortified with 

known chlorine dioxide and chlorite 

concentrations and then analyzed by 

each method. The results of the 

validation study are summarized in 

Smith and Wendelken (2013c). EPA has 

determined that the ChlordioX Plus 

method is equally as effective as the 

approved method, Standard Method 

4500–ClO2 E. The basis for this 

determination is discussed in Smith and 

Wendelken (2013c). Therefore, EPA is 

approving the ChlordioX Plus method 

for determining chlorine dioxide and 

chlorite in drinking water. A copy of the 

method can be obtained by contacting

(Suite 100), Erlanger, KY 41018. 

4. Veolia Water Solutions and 

Technologies Tecta EC/TC Method— 

Presence/Absence Method for the 

Simultaneous Detection of Total 

Coliforms and Escherichia coli (E. coli) 

in Drinking Water (Veolia 2014a). Tecta 

EC/TC is a microbiological method for 

the simultaneous detection of total 

coliforms and E. coli in drinking water 

by broth enrichment of samples. Total 

coliforms and E. coli are detected as 

being present or absent in 100 mL 

samples of drinking water by enzymatic 

cleavage of fluorogenic substances with 

the formation of fluorescent compounds 

after incubation. Approved drinking 

water methods for total coliforms are 

listed at 40 CFR 141.21(f)(3) under the 

Total Coliform Rule (TCR) and at 40 

CFR 141.852(a)(5) under the Revisions 

to the Total Coliform Rule (RTCR). 

Methods approved for E. coli in 

drinking water are listed at 40 CFR 

141.21(f)(6) under the TCR, at 40 CFR 

141.402(c)(2) under the Ground Water 

Rule (GWR), and at 40 CFR 

141.852(a)(5) under the RTCR. Tecta EC/ 

TC is similar to other approved drinking 

water methods except that it uses 

hydrophobic fluorogens for total 

coliforms and E. coli which adhere to a 

hydrophobic plastic stub. These 

fluorogens emit fluorescent light into 

the interior of the stub when 

illuminated by ultraviolet light. The 

fluorescence from the fluorogens is 

detected by a photometer adjacent to the 

stub. The incubation temperature 

maintenance, incubation timing, and 

fluorescence detection and results 

recording are all performed by an 

automated instrument. Tecta EC/TC is 

able to detect total coliforms and E. coli 

in 18 hours. Reagents and sample 

incubation containers are available, 

which can be used with the Tecta EC/ 

TC incubator/detector. An Alternative 

Test Procedure (ATP) study was 

conducted to compare the method 

performance of Tecta EC/TC to the 

performance of the approved methods 

Standard Methods 9221 B (LTB/BGLB 

for total coliforms) and 9221 F (LTB/

EC–MUG for E. coli) (APHA 1998). The 

comparison study involved analyses of 

200 drinking water samples—20 

replicate samples that were inoculated 

with very low densities of chlorinestressed total coliforms or E. coli 

obtained from 10 geographically 

dispersed waste waters. Method 

specificity was evaluated using 

approximately 100 positive and 100 

negative cultures as determined from 

analyses by the reference methods. The 

ATP validation study report (Veolia 

2014b) details the study design and 

method data evaluation. EPA has 

determined that Tecta EC/TC is equally 

effective relative to the approved 

Standard Method 9221 B for total 

coliforms under the TCR and RTCR, and 

Standard Method 9221 F for E. coli 

under the TCR, GWR, and RTCR. The 

basis for this determination is discussed 

in Sinclair (2014). Therefore, EPA is 

approving the Tecta EC/TC method for 

determining total coliforms and E. coli

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.

Partial Exemption of Certain Chemical 

Substances From Reporting Additional 

Chemical Data 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Direct final rule. 

SUMMARY: EPA is amending the list of 

chemical substances that are partially 

exempt from reporting additional 

information under the Chemical Data 

Reporting (CDR) rule. EPA has 

determined that, based on the totality of 

information on the chemical substances 

listed in this document, the Agency has 

low current interest in their CDR 

processing and use information. EPA 

reached this conclusion after 

considering a number of factors, 

including: The risk of adverse human 

health or environmental effects, 

information needs for CDR processing 

and use information, and the 

availability of other sources of 

comparable processing and use 

information. 

DATES: This direct final rule is effective 

August 18, 2014 without further notice, 

unless EPA receives adverse comment 

on or before July 21, 2014. If EPA 

receives written adverse comments, EPA 

will withdraw the applicable partial 

exemption in this direct final rule before 

its effective date. See also Unit II. of the 

SUPPLEMENTARY INFORMATION. 

ADDRESSES: Submit your comments, 

identified by docket identification (ID) 

number EPA–HQ–OPPT–2012–0221, by 

one of the following methods:

SUPPLEMENTARY INFORMATION: 

I. Executive Summary 

A. What action is the agency taking? 

This partial exemption eliminates an 

existing reporting requirement under 40 

CFR 711.6(b)(2). With this direct final 

rule, the following chemical substances 

are being exempted from reporting of 

the information described in 40 CFR 

711.15(b)(4): 1,3-Propanediol (Chemical 

Abstracts Service Registry Number 

(CASRN) 504–63–2); oils, palm kernel 

(CASRN 8023–79–8); and bentonite, 

acid-leached (CASRN 70131–50–9). 

However, by existing terms at 40 CFR 

711.6, this partial exemption will 

become inapplicable to a subject 

chemical substance in the event that the 

chemical substance later becomes the 

subject of a rule proposed or 

promulgated under TSCA section 4, 

5(a)(2), 5(b)(4), or 6, an enforceable 

consent agreement (ECA) developed 

under the procedures of 40 CFR part 

790, an order issued under TSCA 

section 5(e) or 5(f), or relief that has 

been granted under a civil action under 

TSCA section 5 or 7. EPA is also making 

non-substantive technical amendments 

to 40 CFR 711.6(b)(2) to reflect that 

while prior information collections may 

have been styled as either ‘‘IUR 

collections’’ or ‘‘CDR collections,’’ 

prospective obligations are styled as 

‘‘under the CDR.’’ 

B. Why is the agency taking this action? 

This amendment is in response to a 

petition request (Ref. 1) submitted under 

40 CFR 711.6(b)(2)(iii)(A). EPA 

reviewed the information put forward in 

the petition and additional information 

against the considerations listed at 40 

CFR 711.6(b)(2)(ii). EPA’s chemical 

substance-specific analysis is detailed in 

supplementary documents available in 

the docket under docket ID number 

EPA–HQ–OPPT–2012–0221 (Refs. 2, 3, 

and 4). The Agency is adding these 

three chemical substances to the 

partially exempt chemical substances 

list because it has concluded that, based 

on the totality of information available, 

the CDR processing and use information 

for these chemical substances is of low 

current interest. 

C. What is the Agency’s authority for 

taking this action? 

This action is issued under the 

authority of the Toxic Substances 

Control Act (TSCA), 15 U.S.C. 2600 et 

seq., to carry out the provisions of TCSA 

section 8(a), 15 U.S.C. 2607(a). Section 

8(a) of TSCA authorizes EPA to 

promulgate rules under which 

manufacturers of chemical substances 

and mixtures must submit such 

information as the Agency may 

reasonably require. The partial 

exemption list was established in 2003 

(Ref. 5) and can be found in 40 CFR 

711.6. 

D. What are the impacts of this action? 

There are no costs associated with 

this action and the benefits provided are 

related to avoiding potential costs. This 

partial exemption eliminates an existing 

reporting requirement without imposing 

any new requirements. See also the 

discussion in Unit V. 

E. Does this action apply to me? 

You may be potentially affected by 

this action if you manufacture (defined 

by statute at 15 U.S.C. 2602(7) to 

include import) the chemical substances 

contained in this direct final rule. The 

North American Industrial 

Classification System (NAICS) codes 

provided here are not intended to be 

exhaustive, but rather provide a guide to 

help readers determine whether this 

document applies to them. Potentially 

affected entities may include chemical 

manufacturers subject to CDR reporting 

of one or more subject chemical 

substances (NAICS codes 325 and 

324110), e.g., chemical manufacturing 

and petroleum refineries. 

F. What should I consider as I prepare 

my comments for EPA? 

Do not submit Confidential Business 

Information (CBI) to EPA through 

regulations.gov or email. Clearly mark 

the part or all of the information that 

you claim to be CBI. For CBI 

information in a disk or CD–ROM that 

you mail to EPA, mark the outside of the 

disk or CD–ROM as CBI and then 

identify electronically within the disk or 

CD–ROM the specific information that 

is claimed as CBI. In addition to one 

complete version of the comment that 

includes information claimed as CBI, a 

copy of the comment that does not 

contain the information claimed as CBI
