. **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:

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:

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 toperform 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 theresults 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–ClO 2 

### 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–ClO 2 

### 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–ClO 2 

### 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 Palintest Ltd, 1455 Jamike Avenue (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 inoculatedwith 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 in drinking water. Tecta EC/TC is an automated and self-contained method, but is subject to the requirements for certified laboratories described in CFR
141.28.

A copy of the Tecta EC/TC method is available from Veolia Water Solutions

and Technologies, Suite 4697, Biosciences Complex, 116 Barrie Street, Kingston, Ontario, Canada K7L 3N6. 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**

**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
