**ACTION :**  Final rule.

**SUMMARY :**  On May 30, 2012, the U.S. Department of Energy (DOE) issued a notice of proposed rulemaking (NOPR) to amend the test procedures for showerheads, faucets, water closets, urinals, and prerinse spray valves. Following consideration of comments received in response to the NOPR, DOE issued a supplemental notice of proposed rulemaking (SNOPR) on April 8, 2013. The SNOPR included revisions
to the definitions of showerhead and hand-held showerhead; removal of body sprays from the proposed showerhead definition; requirements pertaining to testing of showerheads that are components of shower towers; a
standardized test method to be used when verifying the mechanical retention of a showerhead flow control insert when subject to 8 pounds force (lbf); clarification of permissible trim adjustments for tank-type water closets; amendments to the required static test pressures to be used when testing flushometer valve siphonic and blowout water closets; and clarifications of the definition of basic model with respect to
flushometer valve water closets and urinals, as well as associated changes to certification reporting requirements for both of these products. These proposed rulemakings serve as the basis for this

action.

1 Because of the placement of prerinse spray valves in Part B of Title III of EPCA, the provisions of Part B apply to the rulemaking for commercial prerinse spray valves. The location of the provisions within the CFR does not affect either their substance or applicable procedure; DOE is placing them in the commercial portion of the CFR part as a matter of administrative convenience based on their nature or type. 2 The term ‘‘ANSI’’ is no longer included in the
title of the current versions of either standard. However, ASME, the organization that publishes these standards, is accredited by ANSI as a Standards Development Organization and the standards were approved by ANSI prior to publication. 3. Showerhead Leakage

I. Authority and Background

Title III of the Energy Policy and Conservation Act of 1975 (42 U.S.C.

6291, et seq.; ‘‘EPCA’’ or ‘‘the Act’’) sets forth a variety of provisions designed to improve energy efficiency. (All
references to EPCA refer to the statute as amended through the American Energy Manufacturing Technical Corrections Act (AEMTCA), Public Law 112–210 (Dec. 18, 2012).) Part B of Title III, which for editorial reasons was redesignated as Part A upon incorporation into the U.S. Code (42 U.S.C. 6291–6309, as codified), establishes the ‘‘Energy Conservation Program for Consumer Products Other Than Automobiles,’’ which includes showerheads, faucets, water closets, urinals and prerinse spray valves, the subjects of this notice. (42 U.S.C. 6292(a)(15)–(18) and 42 U.S.C. 6295(dd)) Because prerinse spray valves are generally viewed as commercial equipment, in a final rule published October 18, 2005, DOE placed the regulatory provisions for prerinse spray
valves in Title 10 of the Code of Federal Regulations (CFR), part 431, ‘‘Energy Efficiency Program for Certain
Commercial and Industrial Equipment.’’ 1 70 FR 60407, 60409.

Under EPCA, the energy conservation program consists essentially of four parts: (1) Testing, (2) labeling, (3) Federal energy conservation standards, and (4) certification and enforcement procedures. The testing requirements consist of test procedures that manufacturers of covered products must use as the basis for (1) certifying to DOE that their products comply with the applicable energy and water conservation standards adopted under EPCA, and (2) making representations about the efficiency of those products. Similarly, DOE must use these test procedures to determine whether the products comply with any relevant standards promulgated under EPCA.

EPCA states that the procedures for testing and measuring the water use of
faucets and showerheads shall be
ASME/ANSI standard A112.18.1M– 1989, ‘‘Plumbing Fixture Fittings,’’ for faucets and showerheads, and ASME/ ANSI standard A112.19.6–1990, ‘‘Hydraulic Requirements for Water Closets and Urinals,’’ for water closets and urinals; EPCA further specifies that
if ASME/ANSI revises these requirements, the Secretary shall adopt such revisions if they conform to the basic statutory requirements for test procedures. (42 U.S.C. 6293(b)(7)–(8))

EPCA states that the test procedure for measuring the flow rate for commercial prerinse spray valves ‘‘shall be based on [the] American Society for Testing and Materials (ASTM) standard F2324,
entitled ‘Standard Test Method for PreRinse Spray Valves.’ ’’ (U.S.C. 6293(b)(14)) In a final rule published on December 8, 2006, DOE incorporated by
reference the 2003 version of ASTM standard F2324 at 10 CFR 431.263, and
established it as the uniform test
method for the measurement of flow rate of commercial prerinse spray valves

at 10 CFR 431.264. 71 FR 71340.

DOE last amended test procedures for showerheads, faucets, water closets, and urinals in a final rule published in March 1998 (Mar. 1998 final rule), which incorporated by reference ASME/ ANSI standard A112.18.1M–1996, ‘‘Plumbing Fixture Fittings,’’ for showerheads and faucets, and ASME/ ANSI standard A112.19.6–1995, ‘‘Hydraulic Performance Requirements for Water Closets and Urinals,’’ for
water closets and urinals. 63 FR 13308 (March 18, 1998). Since publication of the March 1998 final rule, ASME has revised both procedures and issued the most recent versions as A112.18.1–2012, ‘‘Plumbing Supply Fittings,’’ for
showerheads and faucets in December 2012, and A112.19.2–2008, ‘‘Ceramic Plumbing Fixtures,’’ for water closets and urinals in August 2008. 2

DOE published the proposed amendments to the test procedures for showerheads, faucets, water closets, urinals, and prerinse spray valves in a test procedure NOPR in the Federal Register on May 30, 2012 (May 2012 NOPR). The NOPR proposed generally to incorporate the revised versions of
the ASME standards discussed in the previous paragraph, as well as an updated version of the test standard for commercial prerinse spray valves and
certain revisions and additions to the definitions of covered plumbing products in 10 CFR 430.2. On July 24, 2012, DOE held a public meeting to discuss amendments proposed in the May 2012 NOPR and provided an opportunity for interested parties to
comment. DOE also received written comments from interested parties regarding the proposed amendments to the test procedures.

Upon review of the comments received in response to the May 2012 NOPR, several issues emerged that required additional clarification or information before publishing a final rule. In response to those comments, a supplemental notice of proposed rulemaking (SNOPR) was published in
the Federal Register on April 8, 2013 (April 2013 SNOPR). The issues addressed in the April 2013 SNOPR
included revisions to the definitions of showerhead and hand-held showerhead; clarification of the requirements pertaining to testing of shower towers;
a standardized test method to be used when verifying the mechanical retention
of a showerhead flow control insert when subjected to 8 pounds force (lbf); clarification of permissible trim adjustments for tank-type water closets; and amendments to the required static test pressures to be used when testing

4 A notation in the form ‘‘Kohler, No. 9 at p. 4’’
identifies a written comment that DOE has received and included in the docket of this rulemaking. This particular notation refers to a comment: (1) Submitted by Kohler; (2) in document number 9 of the docket; and (3) on page 4 of that document.

5 A notation in the form ‘‘NRDC, Public Meeting Transcript, No. 11 at pp. 54–55’’ identifies a
comment that DOE has received and included in the docket of this rulemaking. This particular notation refers to a comment: (1) Submitted by NRDC during the public meeting; (2) in the transcript of that public meeting, document number 11 in the docket of this rulemaking; and (3) appearing on pages 54 and 55 of the transcript. flushometer valve siphonic and blowout water closets. DOE also proposed
further clarification of the definition of basic model with respect to flushometer valve water closets and urinals, as well as associated changes to certification reporting requirements for these products. DOE received written comments from interested parties regarding the amended proposals.

On July 30, 2013, DOE held an additional public meeting to receive
additional comments on DOE’s proposed test to verify mechanical
retention of a showerhead flow control insert when subjected to 8 lbf. DOE also accepted written comments for 10 days following the public meeting, with the comment period closing on August 9, 2013. 78 FR 42719 (July 17, 2013). Because DOE has not yet been able to
consider all comments raised at this meeting and during the additional comment period, DOE has not finalized this proposal and will address this issue in a separate notice.

General Test Procedure Rulemaking

Process

Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures DOE must follow when prescribing or amending test procedures for covered products. EPCA provides that any test procedures prescribed or amended under this section shall be reasonably designed to produce test results which measure energy efficiency, energy use, water use (in the case of showerheads, faucets, water closets and urinals), or estimated annual operating cost of a covered product during a representative average use cycle or period of use and shall not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))

In addition, if DOE determines that a test procedure amendment is warranted, it must publish proposed test procedures and offer the public an opportunity to present oral and written comments on them. (42 U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test procedure, DOE must determine to what extent, if any, the proposed test procedure would alter the measured energy efficiency or energy use, or, in this case, water use, of any covered product as determined under the existing test procedure. (42 U.S.C. 6293(e)(1)) If DOE determines that the amended test procedure would alter the
measured water use of a covered product, DOE must amend the applicable water conservation standard accordingly. (42 U.S.C. 6293(e)(2))

Effective 180 days after an amended test procedure applicable to a covered product is prescribed, no manufacturer may make any representation with respect to water usage of such product unless such product has been tested in
accordance with such amended test procedure and such representation fairly discloses the results of such testing. (42 U.S.C. 6293(c)(2)) However, the 180-day period may be extended for an additional 180 days if the Secretary determines that this requirement would impose an undue burden. (42 U.S.C. 6293(c)(3))

II. Summary of the Final Rule

The final rule amends the current DOE test procedures for showerheads, faucets, water closets, urinals, and prerinse spray valves. DOE has concluded that these changes will not
affect measured water use of these products. Instead, they will primarily clarify the manner in which to test for compliance with the current water
conservation standards. As indicated in greater detail in the ‘‘Discussion’’ section of this notice, these amendments apply to the current test procedures in 10 CFR part 430, appendices S and T to subpart B; to the definitions set forth in 10 CFR 430.2; and to 10 CFR part 431, subpart O. DOE is making these amendments to eliminate any potential ambiguity contained in these test procedures and clarify the regulatory text so that regulated entities fully understand the intended application and implementation of the test procedures. DOE also notes that this rule also fulfills its obligation to periodically review its test procedures under 42 U.S.C. 6293(b)(1)(A).

III. Discussion

This section discusses the test procedures incorporated into this final rule. This section also presents the
written and oral comments received in response to the May 2012 NOPR, the
written and oral comments received in response to the April 2013 SNOPR, and DOE’s responses to these comments. Responses to the comments address the following subject areas:

1. Showerheads and Faucets
2. Water Closets and Urinals 3. Commercial Prerinse Spray Valves 4. Incorporation by Reference of
Standards
5. Basic Models 6. Statistical Sampling Plans
7. Information To Be Provided in Certification Reports

A. Showerheads and Faucets

1. Definitions

To address certain provisions of the
revised ASME A112.18.1 that were not contemplated in the versions referenced by the existing DOE test procedures, and to establish greater clarity with respect to product coverage, DOE proposed in the May 2012 NOPR to adopt new definitions for the terms ‘‘accessory,’’ ‘‘body spray,’’ ‘‘hand-held shower,’’ and ‘‘fitting’’ based on the definitions for these components in the most recent ASME standard. 77 FR 31747–48 (May 30, 2012)

In the May 2012 NOPR, DOE proposed to define a showerhead as ‘‘an accessory, or set of accessories, to a supply fitting distributed in commerce for attachment to a single supply fitting, for spraying water onto a bather, typically from the overhead position, including body sprays and hand-held showerheads, but excluding safety
shower showerheads.’’ 77 FR at 31755 (May 30, 2013). DOE proposed a
modification to the definition of the
term ‘‘showerhead’’ based on a
definition included in ASME

A112.18.1. 3 With the proposed modification, DOE intended to reflect that safety shower showerheads are not covered products, while hand-held showerheads are covered. The proposed
definition also clarified that DOE would consider a body spray to be a showerhead for the purposes of regulatory coverage.

Kohler and Sloan Valve Company (Sloan Valve) recommended that, for consistency, DOE should use the
showerhead definition found in ASME A112.18.1: ‘‘An accessory to a supply fitting for spraying water onto a bather, typically from the overhead position.’’ (Kohler, No. 9 at p. 4; Sloan Valve, No. 12 at p. 3) 4

The National Resources Defense Council (NRDC) commented that a
showerhead should not be defined as an accessory. (NRDC, Public Meeting Transcript, No. 11 at pp. 54–55) 5 Plumbing Manufacturers International (PMI), Moen Incorporated (Moen), and Kohler commented that body sprays are not considered accessories since they cannot be readily added or removed by the user, and thus should not be
included in the showerhead definition.


### 62973 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

(PMI, No. 8 at p. 4; Moen, No. 4 at p. 3; Kohler, No. 9 at p. 4) NRDC supported the incorporation of body sprays in the showerhead definition. (NRDC, Public Meeting Transcript, No. 11 at pp. 57–58) The International Code Council (ICC) recommended that the term ‘‘showerhead’’ be incorporated into the definition of body spray to clearly indicate that a body spray is considered a form of showerhead. (ICC, Public Meeting Transcript, No. 11 at pp. 55–56)

Based on these comments, DOE withdrew the proposal to include body sprays in the April 2013 SNOPR, citing a need to further study the issue. 78 FR at 20834 (Apr. 8, 2013). DOE also stated in the April 2013 SNOPR that the
current ASME showerhead definition was not specific enough to address DOE’s regulatory coverage of showerheads by not specifically including hand-held showerheads or excluding safety shower showerheads. 78 FR at 20834 (Apr. 8, 2013). DOE also proposed in the April 2013 SNOPR to remove the term ‘‘accessory’’ from the definition of showerhead in light of
comments received. 78 FR at 20834 (Apr. 8, 2013). The April 2013 SNOPR proposed the following definition for the term ‘‘showerhead’’: ‘‘A component of a supply fitting, or set of components
distributed in commerce for attachment to a single supply fitting, for spraying water onto a bather, typically from an overhead position, including hand-held showerheads, but excluding safety showerheads.’’ 78 FR at 20841 (Apr. 8, 2013). DOE notes that the term used in EPCA is ‘‘safety shower showerhead,’’
and DOE intended for the term in the proposed definition to refer to the same type of product. Accordingly, the
finalized definition of ‘‘showerhead’’ in this rule uses the term ‘‘safety shower
showerhead.’’

DOE received additional comments in response to the revised definition of showerhead proposed in the April 2013 SNOPR. Kohler reiterated its previous comment in support of adopting the
definition of showerhead contained in ASME A112.18.1. (Kohler, No. 27 at p. 1) Comments were also received from PMI, NSF International (NSF), and the International Association of Plumbing and Mechanical Officials (IAPMO), Chicago Faucets, and Moen that supported use of the definition in ASME A112.18.1. (NSF, No. 22 at pp. 1–2; PMI, No. 23 at pp. 2–3; IAPMO, No. 25 at p. 2; Chicago Faucets, No. 27 at p. 1; Moen, No. 30 at p. 1)

Additionally, a number of comments were received regarding DOE’s proposal to adopt a definition of ‘‘showerhead’’ that would not include the term ‘‘body spray’’ and, therefore, exclude body sprays from the current standard. NSF, PMI, IAPMO, Chicago Faucet, and Moen made comments in support of the adoption of the definition of showerhead currently contained in ASME A112.18.1 without edits, with all commenters, except Chicago Faucets, explicitly supporting the decision to exclude body sprays from the definition. (NSF, No. 22 at p. 2; PMI, No. 23 at pp. 2–3; IAPMO, No. 25 at p. 2; Chicago Faucets, No. 28 at p. 1; Moen, No. 30 at p. 1) On the other hand, a joint written comment submitted by NRDC and the Appliance Standards Awareness Project (ASAP) expressed regret regarding the Department’s proposal to remove body sprays from the definition of showerhead, and from regulatory coverage, and further stated that the proposal presented in the SNOPR was ‘‘muddled by the inconsistent and ambiguous use of the term ‘fitting.’ ’’ (NRDC/ASAP, No. 26 at p. 1) Maximum Performance Testing (MaP) noted that removing the term ‘‘body spray’’ from
the definition of showerhead is inconsistent with the general concept of a showerhead since both products serve the same basic purpose, and specifically supported coverage of body sprays as showerheads. (MaP, No. 29 at p. 1) Finally, the California Energy Commission (CEC) stated that DOE’s exclusion of the term ‘‘body spray’’ from
the showerhead definition ‘‘created an exemption from the test procedure so broad that it encompasses showerheads as well.’’ CEC went on to clarify that use of the term ‘‘typically’’ (in the part of the proposed definition that provides that a showerhead sprays water ‘‘typically from an overhead position’’) is ambiguous and ‘‘could lead to a discretionary judgment on what products can be considered not a showerhead’’ because any showerhead that could be placed other than overhead or positioned at lower than usual height could be called a body spray. (CEC, No. 31 at pp. 3–4)

Based on careful consideration of these comments, DOE is excluding the term ‘‘accessory’’ from the showerhead definition and revising the definition to accurately use the term ‘‘supply fitting’’
as it is defined in ASME A112.18.1. The following definition is being adopted in this final rule: ‘‘A component or set of components distributed in commerce for attachment to a single supply fitting, for spraying water onto a bather, typically from an overhead position, including hand-held showerheads, but excluding safety shower showerheads.’’ This final rule is not adopting a definition of body spray. Because the term ‘‘accessory’’ is not used in the definition of showerhead, DOE is not adopting a definition for accessory.

During the July 24, 2012 public meeting, PMI commented that it supported incorporating the definition of hand-held showerhead being developed by ASME: ‘‘An accessory to a supply fitting, that can be hand-held or fixed in place for the purpose of spraying water onto a bather, and which is connected to a flexible hose.’’ (PMI, Public Meeting Transcript, No. 11 at p. 54) Written comments from Moen, PMI, Kohler, and Sloan Valve also supported adoption of ASME’s draft definition of hand-held showerhead. (Moen, No. 4 at p. 3; PMI, No. 8 at p. 4; Kohler, No. 9 at pp. 3–4; Sloan Valve, No. 12 at p. 3) In the April 2013 SNOPR, DOE proposed the following definition for
‘‘hand-held showerhead’’: ‘‘A
showerhead that can be hand-held or fixed in place for the purpose of spraying water onto a bather.’’ 78 FR at
20841. This definition removed the phrase ‘‘and which is connected to a
flexible hose’’ from the ASME handheld showerhead definition because
DOE believed the ASME definition might not encompass all hand-held showerhead configurations in the marketplace.

Following publication of the SNOPR, DOE again received comments that expressed support for the adoption of
the ASME draft definition of hand-held showerhead from NSF, PMI, IAPMO, Kohler and Moen. (NSF, No. 22 at pp. 1–2; PMI, No. 23 at pp. 2–3; IAPMO, No. 25 at p. 2; Kohler, No. 27 at p. 1; Moen, No. 30 at pp. 1–2) In response to DOE’s assertion that the ASME phrase ‘‘and
which is connected to a flexible hose’’ is restrictive and may not cover all configurations, Moen commented that the ASME definition was developed by the ANSI consensus process and that Moen was ‘‘unaware of any hand-held
shower that is connected via some means other than a hose.’’ (Moen, No. 30 at p. 1) No other comments were received in response to the proposed
definition of hand-held showerhead.

DOE also has not identified any products that appear to be intended for
use as a handheld showerhead that do not have a flexible hose, and notes that any product that otherwise meets the
definition of a showerhead would be subject to the 2.5 gpm water consumption standard regardless of
whether it has a flexible hose. Therefore, the definition for hand-held showerhead adopted in this final rule is:
‘‘A showerhead that can be hand-held or fixed in place for the purpose of spraying water onto a bather and that is
connected to a flexible hose.’’

Finally, in the April 2013 SNOPR,
DOE noted that neither EPCA nor 10 CFR 430.2 defines the term ‘‘safety shower showerhead,’’ which is a type of showerhead specifically excluded from coverage by EPCA. 42 U.S.C. 6291(31)(D). DOE noted that lack of a
definition could cause confusion as to which products qualify for exclusion from coverage. 78 FR at 20835. DOE notes that the current Occupational Safety and Health Administration (OSHA) regulation addressing safety showers, which is located at 29 CFR 1910.151(c), does not define the term or specify required characteristics of a safety shower showerhead. However, certain State regulatory requirements that address safety showers use ANSI standard Z358.1, ‘‘Emergency Eyewash and Shower Equipment,’’ as a
reference. 6 This standard contains specific design and performance criteria that safety showers must meet, such as flow rate and accessibility. The ANSI standard defines an emergency shower as ‘‘a device specifically designed and intended to deliver a flushing fluid in
sufficient volume to cause that fluid to cascade over the entire body.’’ DOE requested comments on whether a definition of safety shower showerhead is needed and, if so, whether it is appropriate to define a safety shower
showerhead as ‘‘a showerhead that is designed to meet the requirements of
ANSI standard Z358.1.’’ DOE received comments on the incorporation of a definition of safety shower showerhead consistent with the requirements of
ANSI standard Z358.1 from NSF and PMI, which expressed support for inclusion of a definition of safety shower showerhead. (NSF, No. 22 at p. 2; PMI, No. 23 at p. 3) Kohler indicated it had no comments on adding a definition for safety shower showerhead. (Kohler, No. 27 at p. 1)

After considering the comments received on the NOPR in regard to this proposal, and reviewing potential definitions for ‘‘safety shower showerhead,’’ DOE was unable to identify a definition that would clearly distinguish these products from the
showerheads covered under EPCA.
Because of the additional confusion that may be caused by adoption of an unclear definition, DOE is declining to adopt a definition for the term ‘‘safety
shower showerhead’’ in this final rule. DOE may consider adopting a definition for this term in a future rulemaking. 2. Test Procedure for Showerhead Flow
Control Insert

In addition to setting forth water
conservation standards for showerheads, EPCA also provides that showerheads must comply with the design requirement of section 7.4.3(a) of
ASME/ANSI standard A112.18.1M– 1989 (42 U.S.C. 6295(j)(1)), which requires that if a flow control insert is used as a component of a showerhead,
the showerhead must be manufactured such that a pushing or pulling force of 8 lbf or more is required to remove the

insert.

The current text of 10 CFR 430.32(p) requires that all showerheads manufactured after January 1, 1994, meet the requirements of ASME/ANSI Standard A112.18.1M–1996, 7.4.4(a) (the updated version of the ASME/ANSI provision referenced by EPCA, section 7.4.3(a) of ASME/ANSI A112.18.1M– 1989). As part of this final rule, DOE is incorporating this requirement directly into the text of 10 CFR 430.32(p) in place of a reference to the section 4.11.1 of ASME A112.18.1–2012, which is the updated version of the same provision in section 7.4.4(a) of ASME/ANSI A112.18.1M–1996. However, DOE has
not established a test method to
determine whether showerheads meet the flow control insert retention design requirement. In the May 2012 NOPR, DOE did not propose changes to the showerhead design requirement but
noted that no version of ASME A112.18.1 provides a specific test procedure for verifying that a flow control insert remains mechanically retained when subjected to 8 lbf. DOE requested comments and information on prospective methods of verifying that the design requirement applicable to the flow restrictor has been met, as well as
comments and information on showerhead designs that may complicate verification of the 8 lbf requirement or make verification of the design requirement unnecessary. 77 FR at 31747 (May 30, 2012).

Based on the comments received in response to the May 2012 NOPR and subsequent research, DOE proposed in the April 2013 SNOPR a test method for validating that a given showerhead meets the flow control insert design requirement. DOE received a number of comments in response to the SNOPR expressing concerns about DOE’s proposed test method. (NSF, No. 22 at p. 2, PMI, No. 23 at p. 3, Kohler, No. 27 at p. 2, Chicago Faucet, No. 28 at p. 2, and Moen, No. 30 at p. 2) On July 30, 2013, DOE held a public meeting to explain the proposal in greater detail and to gather additional comments and information about the concerns of stakeholders and the practices currently used by manufacturers to verify compliance with the retention requirement. Because of the comments received during the NOPR and SNOPR comment periods and at the subsequent public meeting, DOE believes further investigation of this issue is necessary to understand clearly any prospective impacts of the proposed test procedure prior to finalizing a test method. Therefore, DOE has decided to address this proposal as part of a subsequent

notice.

3. Showerhead Leakage

During the July 2012 public meeting,
NRDC commented that the showerhead test procedure should clearly state that ball joint leakage from showerheads should be accounted for either by separately measuring and adding leakage to the flow rate determined per
section 5.4 of ASME A112.18.1–2011 (since incorporated into the same section of ASME A112.18.1–2012), or by capturing leakage during the flow rate test itself. (NRDC, Public Meeting Transcript, No. 11 at p. 23) Joint written comments submitted by NRDC and ASAP echoed this comment. (NRDC/ ASAP, No. 14 at pp. 1–2) DOE recognizes that there can be leakage in plumbing systems and agrees that leakage from a ball joint integral to a showerhead should be captured in the overall; flow rate

In addition, DOE believes that proposed amendments to the DOE test procedure, which reference ASME A112.18.1, adequately capture ball joint leakage. ASME A112.18.1 has two optional discharge capacity test schematics allowed for testing flow rate: (1) A metered test set up that measures the flow rate through the specimen, as provided in section 5.4.2.2(c) or; (2) a time-volume test set up, which collects showerhead flow in a receiving container over a given period of time to calculate flow rate, as provided in section 5.4.2.2(d). The metered test set up measures all of the flow through the specimen and therefore will capture ball joint leakage. The time-volume test set up will account for ball joint leakage as long as the container is placed in such a way as to capture all of the flow from the showerhead. Also, DOE notes that ASME A112.18.1, section 5.3.5, sets a maximum leakage rate of 0.01 gallons per minute (gpm) from showerhead ball joints. While DOE does not require compliance with this provision, it
serves as an indication that the amount of leakage expected for products that comply with current industry standards is relatively small. Based on this


### 62975 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

7 WaterSense is a voluntary partnership program administered by the EPA that, among other activities, promotes water conservation by providing certification and labeling for water consuming products, including water closets, that
meet certain water conservation standards. Further
information is available at www.epa.gov/
WaterSense/index.html

. information, DOE will not require a separate test procedure to measure ball joint leakage, but considers ball joint leakage a part of the total flow rate of
a showerhead and has included an
instruction in the showerhead test procedure in Appendix S that if the time/volume method is used, the container must be positioned as to collect all water flowing from the showerhead, including any leakage from the ball joint.

4. Showerhead Test Pressure

At the July 24, 2012 public meeting, NRDC stated that the requirement in
ASME A112.18.1–2011 that showerheads be tested at 80 pounds per square inch (psi) is not representative of pressures experienced in an installation and, in fact, is excessive. (NRDC, Public Meeting Transcript, No. 11 at pp. 22–23) ICC agreed with NRDC that the 80 psi test pressure is excessive and urged DOE to ‘‘correct this obviously excessive number.’’ (ICC, Public Meeting Transcript, No. 11 at pp. 24–25) Although ICC presented anecdotal data at the public meeting, no one provided technical information to DOE as part of the written comments regarding pressures experienced in actual showerhead installations. Additionally, in the public meeting ICC stated that the pressure experienced by a showerhead ‘‘depends on the supply pressure and that varies significantly as you move across the country, and depends significantly on the shower valve and the plumbing system.’’ (ICC, Public Meeting Transcript, No. 11 at p. 26)

Currently DOE does not have sufficient data to provide a basis for revising the showerhead test pressure specified in ASME A112.18.1. Therefore, this final rule does not amend the test pressure for showerheads, but retains the 80 psi requirement present in ASME

A112.18.1.

5. Use of Time-Volume Test Method

During the public meeting, NRDCquestioned the efficacy of the timevolume test method for showerheads in
ASME A112.18.1 and indicated that this test method may increase the amount of error in measured flow rates compared with tests using a flow meter, particularly due to leakage in the fixture and water splashing out of the receiving vessel during testing. (NRDC, Public Meeting Transcript, No. 11 at pp. 22–24) In their joint written comments, NRDC and ASAP stated that Figure 3 in the ASME A112–18.1 test procedure has shortcomings, including the following: (1) It cannot ensure that water will not splatter out of the container during the test; (2) it lacks instructions for measuring the volume of water collected; (3) it does not specify the incremental resolution of the receiving vessel; (4) it does not provide specifics for timing the test; (5) it does not state how many times the test must be repeated; and (6) it does not provide a method for weighting or averaging the results of multiple tests. NRDC and
ASAP concluded that the time-volume
test method set forth in ASME A112.18.1 ‘‘is not specified in sufficient detail to ensure accurate and repeatable results, and should not be part of the federal test method.’’ (NRDC/ASAP, No. 14 at p. 2) DOE understands the concerns of NRDC and ASAP regarding these issues. However, DOE’s review of the updated test procedure for showerheads provided no evidence that
the time-volume test method in ASME A112.18.1 does not meet the statutory requirement for DOE to prescribe test procedures that are reasonably designed to produce test results that measure water use during a representative average use cycle or period of use. (42 U.S.C. 6293(b)(3)) Thus, this final ruleretains the option to use the timevolume test method as specified in

ASME A112.18.1.

6. Testing of Shower Tower Assemblies

In the April 2013 SNOPR, DOE sought to clarify how the requirements of the DOE test procedure apply to shower tower (also known as ‘‘shower panel’’) assemblies. DOE provided context by explaining that ‘‘the term shower tower is typically used in reference to single supply fittings that are designed for
attachment to one or more hot and cold
water connections in a shower or bath and that are composed of at least one showerhead and one or more body sprays, but that may also include a
hand-held showerhead and either a valve for selecting spraying components, a thermostatic mixing valve, or both.’’ 78 FR at 20835 (Apr. 8, 2013). Because DOE had proposed in
the SNOPR a definition of the term ‘‘showerhead’’ that did not include body sprays, DOE also proposed in the SNOPR requiring parties to turn off the body spray component(s) of shower towers during testing of the integral showerhead. 78 FR 20835 (Apr. 8, 2013).

NRDC and ASAP and MaP submitted comments disagreeing with DOE’s proposal to require that body sprays be turned off when testing a shower tower.
NRDC and ASAP stated that the ‘‘approach will yield test results that are not indicative of the water consumption in actual practice . . .’’ (NRDC/ASAP, No. 26 at p. 2) MaP stated that ‘‘there is no reason to ‘turn off’ a portion of a water using system simply because it is
not considered to be included within
the strict definition of a showerhead.’’ (MaP, No. 29 at p. 2) Conversely, Kohler and Moen agreed with DOE’s proposal to turn off body spray components of shower towers for testing. (Kohler, No. 27 at p. 1; Moen, No. 30 at p. 2)

Based on the comments received and
further research into shower towers/ shower panels, DOE concluded that these products contain components that are currently subject to water conservation standards, namely
showerheads and hand-held showerheads. Therefore, in the final rule DOE requires that when testing shower towers/shower panels, the showerhead portion that is subject to
standards must be tested in accordance with the DOE test procedure. When testing a covered product for maximum flow in accordance with Appendix S, which incorporates by reference ASME A112.18.1 section 5.4, the full flow shall be diverted to the covered component being tested. Where it is not possible to isolate the portion of the shower tower subject to the water consumption standard, all components shall be flowing at the maximum rate and the showerhead measured separately.

B. Water Closets and Urinals

1. Dual-Flush Water Closets

In the May 2012 NOPR, DOE proposed a test method to account forthe reduced average water use of dualflush water closets, which are capable of being flushed in either a full-volumeflush mode (full flush) or in a reducedvolume mode (reduced flush). Under the proposed test procedure, the flush
volume of the reduced flush would be measured using section 7.4 of ASME
A112.19.2 in the same manner as the full flush, and the average representative water use would be calculated using the composite average
of two reduced flushes and one full flush. 77 FR at 31746 (May 30, 2012). This proposed method was based upon the test method used by the Environmental Protection Agency (EPA) WaterSense program 7 for measuring the
flush volume of dual-flush water closets and used a weighted average of the full
and reduced flush volumes.

However, since the Federal water consumption standard is based upon the


### 62976 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

maximum water use, DOE did not propose to make this test method the required means for testing dual-flush water closets for the purposes of
certification in accordance with 10 CFR part 429. Rather, the intent in including this test method was to provide manufacturers with a potential means to evaluate the representative water use of these products under conditions of expected consumer use for the purposes of labeling and other representations. For products that do not have dual-flush capability, the method required for
certification would remain the standard full-flush volume test procedure.

In response to the NOPR, DOE received several comments that opposed incorporation of the proposed test method for dual-flush products. The Alliance for Water Efficiency (AWE), Kohler, Moen, and Sloan Valve
commented that because of DOE’s statutory authority, which addresses only the maximum water use of water closets, dual-flush water closets should only be tested in full-flush mode in
accordance with ASME A112.19.2. (AWE, No. 13 at p. 2; Kohler, No. 9 at pp. 2–3; Moen, No. 4, p. 2; Sloan Valve, No. 12, p. 2). Also, AWE, ICC, Kohler, MaP, Moen, NRDC and ASAP, andSloan Valve stated that the weightedaverage approach was unproven and that the particular ratio required further
evaluation to confirm its representativeness. (AWE, No. 13 at p. 2; ICC, Public Meeting Transcript No. 11 at pp. 36–37; Kohler, No. 9 at pp. 2– 3; MaP, No. 10 at pp. 3–4; Moen, No. 4 p. 2; NRDC/ASAP, No. 14 at pp. 3–4; Sloan Valve, Public Meeting Transcript, No. 11 at pp. 38–39) In addition, Kohler, Moen, and Sloan Valve stated that confusion in the marketplace might
result if DOE were to issue a method
different from the WaterSense method to determine the representative average
flush volume for dual-flush water closets. (Kohler, No. 9 at pp. 2–3; Moen, No. 4 at p. 2; Sloan Valve, No. 12 at p. 2) As a result of these comments, DOE proposed in the April 2013 SNOPR to
not include a dual-flush test method in appendix T to subpart B of 10 CFR part 430, and instead to indicate specifically in § 429.30 of 10 CFR part 429 that the flush volume to be reported to DOE in certifications of compliance for water
closets is the full-flush volume. The California Investor Owned Utilities (CA IOUs) subsequently submitted multiple
comments that revolved around the issue of adopting test procedures to accurately estimate flush volume of dual-flush water closets. Specifically, the CA IOUs commented that: (1) DOE should establish an appropriate ratio of full-volume to reduced-volume flushes that is to be used in determining arepresentative flush volume for dualflush water closets; (2) there is evidence that a 2:1 ratio is too high and is variable, depending on the application; (3) DOE should conduct research to determine the appropriate ratio; (4) a nationally established representative
flush volume would resolve conflicts between different test procedures adopted by states and lessen the burden on manufacturers; (5) the definition of a
water closet needs to be modified toincorporate the ratio of reduced- to fullvolume flushes; (6) if DOE intends to
establish a standard based on effective flush volume, DOE should use this rulemaking to develop a test procedure; and (7) manufacturers should be required to certify dual-flush water closets for both flush rates. (CA IOUs, No. 24 at pp. 2–3) NRDC and ASAP stated that they believe DOE should establish a procedure for representative average flush rate for dual-flush water closets, but recommended that this be done in another rulemaking. (NRDC/ ASAP, No. 26 at p. 3)

In contrast with these comments, Chicago Faucets submitted a comment that stated, ‘‘We believe that the DOE
mandate is to enforce the maximum flush volume of 1.6 gallons per flush (gpf).

The best method to achieve this is to
maintain the references to the test protocols of the ANSI accredited
standard ASME A112.19.2/CSA B45.1. There is no justification for DOE to create a new standard.’’ Chicago Faucets
added that it believes a 2:1 ratio of
reduced- to full-volume flush is conservative, and that 3:1 or 4:1 is likely more representative of actual water use in dual-flush water closets. (Chicago Faucets, No. 28 at p. 2)

For clarification, DOE did not intend to establish through its proposal a separate standard for dual-flush products or to require separate certification requirements for these products, and emphasizes that manufacturers of any type of covered water closet are only required to certify maximum water use ( see 10 CFR 429.30(b)(2)). DOE also notes that the
manufacturer would not have been required under the NOPR proposal to
test dual-flush toilets in both the fullflush modes and the reduced-flush
modes if the manufacturer did not intend to make representationsregarding average water use of dualflush water closets.

However, based on the comments submitted, DOE has determined that it
does not have sufficient evidence on which to base a test procedure for average representative water use for dual-flush water closets. Therefore, DOE is not adopting a test procedure to calculate average representative water
use for dual-flush water closets.

Regardless, DOE emphasizes that because DOE is not adopting a test procedure to calculate average representative water use for dual-flush water closets, manufacturers, distributors, retailers, and private labelers are not permitted to make any representations of water use ( e.g., average representative water use reflecting an average of the full and reduced flush modes) for dual-flush
water closets other than the maximum
flush volume. Under 42 U.S.C. 6293(c)(1) and (2), none of these regulated parties may make any representation with respect to the water
use of a water closet unless that representation is based on testing
conducted in accordance with the relevant DOE test procedure. In this case, because DOE is not adopting a test procedure to calculate average representative water use, parties may not state, in writing or in any broadcast advertisement, a specific value for the average representative water use of a dual-flush water closet. Reported flush volumes may only represent the flush
volume of the full-flush mode in
accordance with the DOE testprocedure. Parties may state that a dualflush water closet complies with the requirements of EPA’s WaterSense program, either in writing or through use of the appropriate WaterSense label, as long as such representations are made in accordance with EPA specifications and such representations do not include a specific value of average representative water use.

During the July 24, 2012 NOPR public meeting, ASAP inquired whether WaterSense would be required to use the same test procedure proposed by DOE in the NOPR for representative average water use for dual-flush water closets. (ASAP, Public Meeting Transcript, No. 11 at p. 33) This rule is not adding a test procedure for representative average water use of dual
flush water closets and therefore will
have no effect on the WaterSense specification. In addition, since WaterSense is a voluntary program, the specifications for labeling WaterSense products may include additional requirements that are beyond the requirements of the DOE test procedure as long as the DOE test procedure is the basis for measuring water consumption.

At the July 24, 2012 NOPR publicmeeting, ICC inquired whether dualflush devices intended to retrofit single flush flushometer-style water closets are


### 62977 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

8 At the time of this final rule, ASME A112.19.2– 2013 had just been published. Because DOE did not
have sufficient time in which to review the revised version, DOE was unable to incorporate the revised version by reference in this rule. DOE will consider adoption of the 2013 version of A112.19.2 in a future rulemaking. required to meet the appropriate flush volume standards. (ICC, Public Meeting Transcript, No. 11 at p. 38) (See 10 CFR 430.32(q).) Retrofit devices are not covered products because they do not
meet the definition of a water closet in
10 CFR 430.2 and therefore are not required to be tested under the DOE test procedures for maximum flush volume.

2. Static Test Pressure for Flushometer Valve Siphonic and Blowout Water
Closets

In written comments submitted to DOE following publication of the May 2012 NOPR, NRDC and ASAP
recommended that DOE evaluate the effect of averaging test results that have been obtained at different test pressures of siphonic flushometer style water closets, which is the general method
used in both ASME/ANSI A112.19.6–
1995 referenced in the DOE test procedure for water closets and in the newer ASME A112.19.2–2008. (NRDC/ ASAP, No. 14 at p. 2) NRDC and ASAP further suggested that DOE should require reporting of the higher water consumption value obtained by (1) averaging three tests at 80 psi and (2) averaging three tests at 35 psi for siphonic flushometer water closets and, at a minimum, should discard the 2:1 ratio of test results at the lower pressure. (NRDC/ASAP, No. 14 at p. 2) Although not specifically mentioned by NRDC and ASAP in their comments, DOE also proposed in the May 2012 NOPR to require an additional low pressure test at 45 psi for blowout flushometer water
closets that would result in a 2:1 ratio
of results. 77 FR at 31745.

In the April 2013 SNOPR, DOE agreed that the use of a 2:1 ratio for averaging water consumption of flushometer siphonic and blowout water closets at the pressures currently indicated in
Table 5 of ASME A112.19.2–2008 could
lead to results that are not representative across a range of pressures. For this reason, DOE proposed that the test pressures for
flushometer valve water closets with a siphonic bowl be 80 psi and 35 psi. For
flushometer valve water closets with a blowout bowl, DOE proposed that the test pressures be 80 psi and 45 psi. According to this proposal, the test shall be run three times at each pressure as specified in section 7.4.3, ‘‘Procedure,’’
of ASME A112.19.2–2008. 78 FR at

20842.

In comments on the April 2013 SNOPR, NSF, PMI, IAPMO, Kohler, and Chicago Faucet stated that the requirements in Table 5 of ASME A112.19.2–2008 were published incorrectly. (NSF, No. 22 at p. 3; PMI, No. 23 at pp. 5–6; IAPMO, No. 25 at p. 2; Kohler, No. 27 at pp. 2–3; Chicago Faucet, No. 28 at p. 2) The commenters
stated that the ASME A112 committee
has addressed the error and in 2013 will publish a revision to the standard mirroring DOE’s April 2013 SNOPR proposal. 8

NRDC and ASAP re-stated their recommendation that, in order to ensure that test reporting does not obscure efficiency actually experienced by building owners, DOE ‘‘should require reporting of the higher water consumption value obtained by the average of three tests at 80 psi and the average of three tests at 35 psi. At a minimum, these values should be reported separately even if averaging is permitted to demonstrate compliance.’’ (NRDC/ASAP, No. 26 at p. 3)

Based on the comments received in response to the SNOPR, DOE, in this final rule, adopts the requirement that water consumption tests be conducted at two static pressures, with three tests at each pressure ( i.e., six total tests, rather than nine). For flushometer valve water closets with a siphonic bowl, DOE requires that the test pressures be 80 psi and 35 psi. For flushometer valve water closets with a blowout bowl, DOE requires that the test pressures be 80 psi and 45 psi. According to this amendment, the water consumption test shall be run three times at each pressure as specified in section 7.4.3, ‘‘Procedure,’’ of ASME A112.19.2–2008.
The recorded flush volume for each tested unit shall be the average of the
total flush volumes obtained over the range of pressures specified above.

3. Water Closet and Urinal SensorActivated Flush Testing

NRDC and ASAP commented that
water closet and urinal flush valves that are activated automatically by a sensor are not adequately tested under the ASME test procedures. NRDC and ASAPclaimed that these types of sensoractivated flush valves can cause ‘‘phantom flushing’’ ( i.e., unintended flushing by the sensored-valve) and lead
to excessive water use. NRDC and ASAP requested that DOE develop test procedures to address this issue. (NRDC/ASAP, No. 14 at p. 3) While DOE understands that such phantom flushing may be a concern, the DOE water consumption standards for water closets and urinals, found at 10 CFR sections 430.32(q) and 430.32(r), respectively, are measured in gallons per flush and do not include annual water consumption. While phantom
flushes affect the annual water consumption of these products, they do not affect the water use of a single flush. The test procedures for flush valves for water closets and urinals are only
intended to measure the flush volume of a single flush. The purpose of this rulemaking is to update the DOE test procedures. Introduction of a new test procedure for sensor-activated flush valves is outside of the scope of this rulemaking.

4. Test Procedure Amendments for Gravity Flush Tank Water Closet Trim Adjustments

In written comments submitted to DOE and in oral comments made during the July 24, 2012 NOPR public meeting, NRDC and ASAP urged DOE to consider requiring manufacturers to adjust the tank trim components to the maximum flush volume setting during testing. (NRDC, Public Meeting Transcript, No. 11 at pp. 70–71; NRDC/ASAP, No. 14 at p. 3) The term ‘‘tank trim’’ refers to the components in the tank that can be adjusted by the consumer such as the water level, fill valve timing, and related components. While DOE’s current test procedure does not address this issue, ASME A112.19.2–2008, section 7.1.2, specifies that for gravity flush tank water closets, the water level in the tank and fill time shall be adjusted in
accordance with the manufacturer’s instructions and specifications at each test pressure. Table 5 in ASME A112.19.2–2008 specifies that ‘‘[a]djustments to tank trim components shall be permitted only when changes to test pressures are indicated’’ and that ‘‘[n]o adjustments shall be allowed between tests employing like pressures.’’ These provisions ensure that
once the trim is set to the manufacturer’s specifications, the water level and fill time adjustments remain
the same for tests that use like pressures, which simulates how water
closets are used in real-world application.

After receiving comments from NRDC and ASAP, DOE investigated water
closet manufacturers’ instructions on gravity flush tank trim adjustments. Based upon a review of installation instructions for representative models from eight separate manufacturers, which represent a significant sampling of major manufacturers of tank-type water closets currently on the market, DOE believes it to be likely that the majority of manufacturers’ installation instruction manuals for gravity flush tank water closets specify the tank water


### 62978 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

level and also provide directions on adjusting the tank’s water level. However, DOE found that few manufacturers provide information on the recommended adjustment of other trim components, such as the flapper
valve or fill valve. Section 7.1.2 of ASME A112.19.2–2008 only specifies adjustments made to the tank water level and fill time and does not specify adjustments made to other trim components such as the flapper valve. Taking into account the variety of water closet designs on the market, it is unclear whether the impact on flush volume of trim adjustments that are not specified in manufacturer’s instructions

or in ASME A112.19.2–2008 is significant.

Based on these findings, in the April 2013 SNOPR, DOE proposed to amend the test procedures for gravity flush tank toilets to require that, at each test pressure specified in Table 5 of ASME A112.19.2–2008, trim components of gravity flush tank water closets that can be adjusted to cause an increase in flush volume, including (but not limited to) the flapper valve, fill valve, and tank water level, be set in accordance with the printed installation instructions supplied by the manufacturer. For products with instructions that do not specify trim setting adjustments, DOE proposed to require that these trim components be adjusted to the maximum water use setting so that the maximum flush volume is produced without causing the water closet to malfunction or leak. In this context, DOE interprets ‘‘malfunction or leak’’ to mean that the product is otherwise unable to meet the requirements of the
ASME A112.19.2 standard for basic functionality. In addition, the water
level in the tank would be set to the maximum level indicated in the printed installation instructions supplied by the
manufacturer or the water line indicated on the tank itself, whichever is higher. DOE also proposed to require that if the product’s installation instructions or the
water closet tank do not indicate a water level, the water level must be adjusted

to 1 ± 0.1 inches below the top of the
overflow tube or 1 ± 0.1 inches below the top rim of the water-containing vessel (for gravity flush tank water
closets that do not contain an overflow tube) for each designated pressure specified in Table 5 of ASME

A112.19.2–2008.

In response to this proposal in the SNOPR, American Standard, NSF, PMI, and Chicago Faucets submitted comments stating that trim adjustments to gravity tank water closets are already covered in ASME A112.19.2–2008, and
that there is no need to deviate from this national standard. These comments also stated that any adoption of changes to trim adjustments should be managed by ASME through a consensus process. (American Standard, No. 21 at p. 1; NSF, No. 22 at p. 3; PMI, No. 23 at p. 5; Chicago Faucets, No. 28 at p. 2) American Standard argued that
consumers would be less satisfied with the proposed adjustments because of the reduced water pressure brought about by a lower water level. (American Standard, No. 21 at p. 1)

Chicago Faucets specifically commented that proposed trim adjustments will not reduce water consumption in water closets and ‘‘adjusting the time of the fill valve in a wash down gravity flush water closet
does not affect the flush volume . . . . If the valves are not adjustable then the instructions are not relevant.’’ (Chicago Faucets, No. 28 at p. 2)

Comments received from Kohler and IAPMO agreed with DOE’s proposed gravity tank water closet trim adjustments and states that a majority of manufacturers provide adequate instructions pertaining to proper tank component settings at the intended flush volumes. (Kohler, No. 27 at pp. 2– 3; IAPMO, No. 25 at p. 2)

Based on comments received and research conducted, DOE has concluded the specifications in ASME A112.19.2– 2008 may not be adequate to ensure that manufacturers test gravity tank water
closets at the maximum flush volume.
DOE does not believe that trim adjustments will cause consumers to be
less satisfied with the water closet performance. The water closet design should provide a proper flush performance that does not exceed the maximum flush volume, and the tank water level and other component settings (such as the flapper valve) should be adequate in meeting this requirement. Therefore, in this final rule, DOE is establishing a requirement that at each test pressure specified in Table 5 of ASME A112.19.2–2008, trim components of gravity flush tank water closets that can be adjusted to cause an increase in flush volume, including (but not limited to) the flapper valve, fill valve, and water tank level, shall be set in accordance with the printed installation instructions supplied by the manufacturer. For products with instructions that do not specify trim setting adjustments, trim components shall be adjusted to the maximum water use setting so that the maximum flush volume is produced without causing the
water closet to malfunction or leak. In this context, DOE interprets
‘‘malfunction or leak’’ to mean that the product is otherwise unable to meet the requirements of the ASME A112.19.2– 2008 standard for basic functionality. In addition, the water level in the tank
shall be set to the maximum level indicated in the printed installation instructions supplied by the
manufacturer or the water line indicated on the tank itself, whichever is higher. If the product’s installation instructions
or the water closet tank do not indicate a water level, the water level shall be adjusted to 1 ± 0.1 inches below the top
of the overflow tube or 1 ± 0.1 inchesbelow the top rim of the watercontaining vessel (for gravity flush tank
water closets that do not contain an overflow tube) for each designated pressure specified in Table 5 of ASME

A112.19.2–2008.

MaP, NRDC and ASAP, and PMI
recommended that DOE follow the WaterSense specification for gravity tank water closet trim adjustments and stated that the WaterSense specification is a validated procedure that has been used on thousands of products. (MaP, No. 29 at p. 2; NRDC/ASAP, No. 26 at pp. 2–3; PMI, No. 23 at p. 5) Specifically, NRDC and ASAP stated, ‘‘field adjustability is a significant cause of excessive water consumption by nominally compliant tank-type water closets at the point of use and the USEPA WaterSense specification for tanktype toilets incorporates specific language on field adjustability, and limits the effects of adjustability to 0.4 gallons per flush in additional consumption.’’ NRDC and ASAP went on to state, ‘‘Although the specific allowance of 0.4 gpf used by
WaterSense should be examined further by DOE before incorporation into the federal test procedure, the frame developed by WaterSense is one that the Department should consider in this rule-making.’’ (NRDC/ASAP, No. 26 at pp. 2–3)

After consideration of these comments, DOE will not adopt the WaterSense specifications for gravity tank water closet trim adjustments. The WaterSense specification provides a special allowance to address field adjustments to trim settings, which are outside the scope of the water consumption test required by DOE and which may add confusion to compliance with Federal requirements if added to the regulations. Specifically, the WaterSense specification permits
the maximum volume of water that can be discharged by the water closet when field adjustment of the tank trim is set at the maximum use setting to be as high as the following values: 1.68 gpf for single-flush water closets and 2.00 gpf
for dual-flush water closets in the fullflush mode. ( See EPA WaterSense

DOE views the water level and trim settings identified by the manufacturer through the printed instructions supplied with the water closet and marked on the tank as the settings for expected consumer use, and would require use of the maximum settings only in cases where the manufacturer has provided no instructions or markings regarding these settings.
Because the allowances in the WaterSense specification address water consumption under conditions outside of those which DOE has previously determined to be representative of expected consumer use, DOE declines to adopt these specifications. DOE notes that any basic model that, under the DOE test procedure, must be tested using the maximum trim setting must meet the applicable Federal standard when tested using that maximum trim setting.

5. Annual Water Consumption Metric

During the July 24, 2012 NOPR public meeting and in written comments, NRDC and ASAP proposed that DOE
consider the use of an annual water consumption metric and associated test procedure for water closets, reasoning
that ‘‘if all new water closets were required to certify an annual consumption rate that incorporated a
reasonable limitation on losses due to leakage, the federal efficiency standard would more effectively encourage the use of designs and materials that eliminate leakage altogether.’’ (NRDC, Public Meeting Transcript, No. 11 at pp. 72–73; NRDC/ASAP, No. 14 at p. 4) More specifically, NRDC and ASAP recommended the incorporation by reference of ASME A112.19.5–2011, ‘‘Flush valves and spuds for water closets, urinals, and tanks,’’ which addresses leakage for those products. (NRDC/ASAP, No. 14 at p. 4)

DOE notes that the purpose of the current rulemaking is to update the existing DOE test procedures, which are prescribed primarily for measuring the
maximum flush volume of water closets and for verifying compliance with the applicable Federal water consumption
standards. The Federal standard does not include a limit on annual water use, nor do DOE’s test procedures include a
measurement of annual water use. Further, in accordance with EPCA, DOE is required to consider the most current version of industry standards, which do
not address annual water use of these products. 42 U.S.C. 6293(b)(8) Finally, DOE does not currently have enough data to develop a test procedure for quantifying annual water use of water closets. Development of such a metric would likely require consideration of issues such as usage patterns for theproducts, flushing patterns of sensoroperated valves, and leakage. Thus,
introduction of an annual water use metric is outside of the scope of the current rulemaking.

6. Trough Urinal Reporting Requirements

In the April 2013 SNOPR, DOE noted that the reporting requirement for trough urinals in § 429.31(b)(2) requires reporting of water consumption for these products in gallons per minute (gpm). DOE stated that the appropriate unit of measurement for reporting water consumption of trough-type urinals should be gpf in accordance with the
Federal standard contained in 10 CFR 430.32(r) and proposed to update the requirement in § 429.31(b)(2) to reflect that the water consumption of urinals be reported in gpf. 78 FR at 20841.

In response, three interested parties provided feedback on the proposal. PMI, IAPMO, and Kohler all commented that trough-type urinals are not equipped with a flushing mechanism and therefore water consumption cannot be measured using gpf. (PMI, No. 23 at p. 6; IAPMO, No. 25 at p. 2; Kohler, No. 27 at p. 3)

Based on these comments, DOE reviewed the requirements of 10 CFR sections 429.31(b)(2) and 430.32(r) and found that it was in error in the April

2013 SNOPR. DOE water conservation standards for trough urinals are based on maximum flow rate ( i.e., gallons per minute, not gallons per flush). Therefore, DOE withdraws the proposal set forth in the April 2013 SNOPR torequire water consumption for troughtype urinals to be reported in gallons per flush. The language currently contained in 10 CFR 429.31(b)(2) regarding the reporting of water consumption of trough-type urinals will remain unchanged.

C. Commercial Prerinse Spray Valves

In the May 2012 NOPR, DOE proposed to update its test procedures to adopt the industry standard for prerinse spray valve testing to ASTM
standard F2324–2009. DOE noted in the NOPR that no changes had been made to the standard, and that only the date had been updated from 2003 to 2009. 77 FR 31746 (May 30, 2012). MaP, NRDC, and Chicago Faucets commented that test procedures for prerinse spray valves in ASTM standard F2324–09 were being updated to reflect new performance
tests that correlate with user satisfaction. (MaP, No. 10 at p. 5; NRDC, Public Meeting Transcript, No. 11 at pp. 43–44; Chicago Faucets, Public Meeting Transcript, No. 11 at pp. 44–45) DOE notes that it has statutory authority only
as it relates to maximum flow rate of prerinse spray valves and does not have statutory authority over product performance as it relates to user
satisfaction. DOE also notes that the revised test procedure does not change the maximum flow rate for prerinse spray valves. The new version of ASTM
standard F2324 has not been finalized at the time of this final rule, and DOE cannot incorporate by reference a draft test procedure. Thus, this final rule incorporates by reference ASTM standard F2324–09 for testing of commercial prerinse spray valves.

D. Incorporation by Reference of
Standards

1. ASME Standards

In the May 2012 NOPR, DOE proposed to adopt the updated ASME standard (ASME A112.18.1M–2011) to align the DOE test procedures for faucets and showerheads with industry practice. 77 FR 31746 (May 30, 2012).
DOE received comments from Moen and Kohler supporting the incorporation of the updated ASME standard (Moen, No. 4 at p. 1; Kohler, No. 9 at p. 1). PMI, Sloan Valve, and AWE also commented in favor of DOE adopting the updated reference to ASME A112.18.1, but
included a statement that the standard should be incorporated in its entirety without edits, modifications, or exceptions. (PMI, No. 8 at p. 2; Sloan Valve, No. 12 at p. 1; AWE, No. 13 at p. 1) NSF and PMI submitted similar comments following publication of the April 2013 SNOPR. (NSF, No. 22 at pp. 2–3; PMI, No. 23 at pp. 2–3) DOE did not receive any comments objecting to the proposal.

Subsequently, ASME A112.18.1– 2012, which is identical to ASME
A112.18.1–2011 in the sections referenced by DOE, has been reviewed by the American National Standards Institute (ANSI) and was approved in December 2012. Furthermore, ASME A112.18.1–2012 has been adopted by
the Canadian Standards Association (CSA) as CSA B125.1. DOE has
reviewed ASME A112.18.1–2012 and finds that it meets the requirements of 42 U.S.C. 6293(b)(7)(B). In response to
the comment that the entire standard should be incorporated, DOE is only incorporating those sections relevant to
measurement of the flow rate of these covered products. Therefore, this final


### 62980 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

rule incorporates by reference section 5.4, Flow Rate, of ASME A112.18.1– 2012, ‘‘Plumbing Supply Fittings,’’ for
faucets and showerheads.

In the May 2012 NOPR, DOE also proposed to adopt the updated ASME standard (ASME A112.19.2–2008) to align the DOE test procedures for water closets and urinals with industry practice. 77 FR 31746 (May 30, 2012).
ASME A112.19.2–2008 has been reviewed by ANSI and was approved on August 1, 2008. Furthermore, ASME A112.19.2–2008 has been adopted by
CSA as CSA B45.1–08. Moen and Kohler submitted comments supporting the incorporation of the updated standard (Moen, No. 4 at p. 2; Kohler, No. 9 at p. 2). PMI, Sloan Valve, and
AWE also commented in favor of DOE adopting the updated reference to ASME A112.19.2–2008, but included a
statement that the standard should be incorporated in its entirety without edits, modifications, or exceptions. (PMI, No. 8 at p. 3; Sloan Valve, No. 12 at p. 2; AWE, No. 13 at p. 2) NSF and
PMI submitted similar comments following publication of the April 2013 SNOPR (NSF, No. 22 at p. 3; PMI, No. 23 at p. 5). In response to the comment
that the entire standard should be incorporated, DOE is only incorporating
those sections relevant to measurement of the water consumption of these covered products. DOE has reviewed
ASME A112.19.2–2008 and finds it meets the requirements of 42 U.S.C. 6293(b)(7)(B).

Therefore, this final rule incorporates by reference section 7.1, ‘‘General,’’ and subsections 7.1.1, 7.1.2, 7.1.3, 7.1.4, and 7.1.5 as well as section 7.4, ‘‘Water Consumption Test,’’ of ASME A112.119.2–2008, ‘‘Ceramic Plumbing Fixtures,’’ for water closets. For the testing of urinals, this final rule incorporates by reference section 8.2, ‘‘Test Apparatus and General Instructions,’’ subsections 8.2.1, 8.2.2, and 8.2.3 as well as section 8.6, ‘‘Water Consumption Test,’’ of ASME A112.19.2–2008, ‘‘Ceramic Plumbing

Fixtures.’’

2. Automatic Incorporation of Standards

Moen and Kohler recommended that DOE eliminate a reference to a specific
version of the ASME standards and instead incorporate language in the CFR that requires compliance with the latest revision of the applicable ASME standard within two years after its publication by ASME. (Moen, No. 4 at pp. 1–2; Kohler, No. 9 at pp. 1–2) EPCA specifies that if the test procedure requirements of ASME/ANSI standard
A112.18.1M–1989 and ASME/ANSI
standard A112.19.6–1995 are revised at any time and approved by ANSI, the Secretary shall amend the test procedures to conform to such revised ASME/ANSI requirements unless the Secretary determines by rule that to do so would not meet the requirements of paragraph 42 U.S.C. 6293(b)(3). 42 U.S.C. 6293(b)(7)(B)–(8)(B) EPCA directs that any test procedure prescribed or amended by DOE shall be reasonably designed to produce test results that
measure water use or estimated annual operating cost of a covered product during a representative average use cycle or period of use, as determined by the Secretary, and shall not be unduly
burdensome to conduct. 42 U.S.C. 6293(b)(3)(B) Automatically updating the Code of Federal Regulations (CFR) to the latest published version of the
ASME standard does not allow DOE to review the changes made to ensure that the revisions meet the requirements in 42 U.S.C. 6293(b)(3) regarding representativeness of measurements and
the associated test burden of the procedure. It also would not address the requirement in EPCA for DOE to review test procedures for all covered products every 7 years. 42 U.S.C. 6293(b)(1)(A). Further, the Administrative Procedure Act requires that any substantive amendment to an existing rule be subject to prior notice and an opportunity for public comment. Therefore, DOE is not adopting the
recommendation from Moen and
Kohler.

3. ASTM Standard

In the May 2012 NOPR, DOE proposed to adopt the updated ASTM standard F2324–09 to align the DOE test procedures for prerinse spray valve
maximum flow rate measurement with industry practice. 77 FR 31746 (May 30, 2012). Moen, PMI, MaP, and AWE all commented in favor of DOE adopting the updated reference to ASTM standard F2324–09. (Moen, No. 4 at p. 2; PMI, No. 8 at p. 3; PMI, Public Meeting Transcript, No. 11 at pp. 42–43; MaP, No. 10 at p. 5; AWE, No. 13 at p. 2) DOE has reviewed ASTM standard
F2324–09 and finds that it meets the requirements of 42 U.S.C. 6293(b)(7)(B). Therefore, this final rule incorporates by reference ASTM standard F2324–09,
‘‘Standard Test Method for Prerinse Spray Valves.’’

E. Definition of Basic Model

In the May 2012 NOPR, DOE provided
information on the water closet and
urinal basic model definition and requested comments on the interpretation of the current definition
of a basic model and factors that DOE should consider in clarifying the definition of basic model. DOE
considered evaluation of this issue to be of importance since the water consumption of some types of water closets and urinals, particularly those that use a flushometer valve, must be measured by combining a flushing
mechanism and bowl that are distributed in commerce separately, which could complicate the
identification of basic models for the purposes of testing and certification. During the July 24, 2012 public meeting,
NRDC commented that it is unclear how DOE expects the valve/bowl pairing combination to work in practice with respect to the basic model definition. To illustrate the lack of clarity, NRDC pointed to DOE’s own language indicating that different valve and bowl
combinations could result in different flush volumes. (NRDC, Public Meeting Transcript, No. 11 at pp. 60–61) In follow-up written comments submitted jointly, NRDC and ASAP stated that DOE’s explanation in the NOPR of how the compliance certification accounts for all possible combinations of a valve and bowl failed to ‘‘clarify how a fixture
manufacturer can establish that its bowl cannot be paired with a flushing device that would provide a higher flush volume and still function properly.’’ (NRDC/ASAP, No. 14 at p. 6) NRDC
stated that because DOE is aware of the variability of flush volume based on the valve/bowl combination, it must find a way to verify that products shipped to commerce can reliably meet the standard. Finally, NRDC and ASAP suggested that DOE consider expanding
the definition of ‘‘tested combination’’
in 10 CFR 430.2 to include information specific to water closets and urinals along with their associated flushing devices. (NRDC/ASAP, No. 14 at p. 6) NRDC and ASAP also inquired as to whether new valves shipped into commerce that are not paired with a bowl are covered products and require certification. (NRDC, Public Meeting Transcript, No. 11 at p. 62; ASAP, Public Meeting Transcript, No. 11 at p. 64)

Based on the comments received, DOE further investigated the issues revolving around the basic model
definition and certification of water closets and urinals. In the April 2013 SNOPR, DOE provided information on
the definitions of water closet and
urinal contained in ASME A112.19.2 and 10 CFR 430.2, which both state that these products are receiving vessels that, upon actuation, convey waste through a trap to a drainage system. The flushing device, such as a flushometer valve, does not meet the definition of a


### 62981 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

water closet or urinal, and therefore is not itself a covered produce under DOE’s regulations. 78 FR at 20838 (Apr. 8, 2013). DOE noted that manufacturers are only required to certify the water closet bowl or urinal body, but for proper operation, the receiving vessel must be paired with a valve during testing and operation. 78 FR at 20839 (Apr. 8, 2013). Additionally, water
closet bowls and urinal bodies are designed for specified flush volumes and must be paired with a valve designed to deliver that volume to ensure proper operation.

In order to clarify the requirement for pairing a valve and bowl together for testing, DOE proposed to incorporate by
reference section 7.1.5.2 of ASME A112.19.2–2008, which clearly states
that a flushometer valve must be connected to the test bowl, and specifies that while conducting the water consumption test the valve is required to maintain a peak flow rate. 78 FR at 20839 (Apr. 8, 2013). A similar provision for flushometer urinals was proposed to be incorporated in the May 2012 NOPR. 77 FR at 31745 (May 30, 2012). DOE further proposed to modify the certification requirements in 10 CFR 429.30(b)(2) for water closets and 429.31(b)(2) for urinals to require manufacturers to identify the flushometer valve that was used during the water consumption test.

Following the April 2013 SNOPR, NRDC and ASAP again commented on
the definition of basic model and certification requirements. NRDC and ASAP stated that the proposal fails to require the valve that is actually shipped to be tested and certified and also points out that there is no way to establish that the flush volume rating of the valve used in the test represents the valve flush volume that will be paired with the covered product because other valves are not subject to federally recognized testing and certification. The comment lists other key attributes that
NRDC and ASAP believe DOE’s proposal fails to account for, which include the following: (1) The product category for flushometer water closets and urinals should encompass the valve
and the china because neither alone would meet the product definition; (2) flushometer valves are commonly shipped separately from the china; (3)
water closet bowls and urinal bodies are often shipped without a valve; and (4) ASME A112.19.2–2008 is essentially a test of the valve. (NRDC/ASAP, No. 26 at pp. 3–4). NRDC and ASAP restated their previous proposal that DOE include language in 10 CFR 430.2,
‘‘Tested Combination’’ to include language and procedures specific to water closets and urinals and their associated flushing devices.

DOE also received comments from NSF, PMI and IAPMO that supported the definition of basic model proposed by DOE in the April 2013 SNOPR as well as the incorporation of ASME A112.19.2–2008, Section 7.1.5.2. (NSF, No. 22 at p. 4; PMI, No. 23 at p. 6; IAPMO, No. 25 at p. 2) Kohler requested
clarification that the ‘‘valve’’ is meant to
refer to a flushometer valve and not a
flush valve housed in a toilet tank.
Kohler further stated that standard industry practice ‘‘is such that if a specific flushing device is required to be used with a fixture, this requirement is indicated on the fixture specification
sheet. In the event the fixture specification sheet does not indicate a specific flushing device, any flushing device that operates at the rated marking on the fixture can be used.’’ (Kohler, No. 27 at p. 3)

In response to these comments, DOE notes that the purpose of the information presented in both the May 30, 2012 NOPR and April 8, 2013 SNOPR was not to change the existing
definition of a basic model of a water closet or urinal, but to clarify for
manufacturers how individual models could be grouped together as a single basic model for the purposes of testing and reporting water consumption in
accordance with 10 CFR 429.12. Reported consumption must be based on the maximum flow for a given valve/
china combination. When a manufacturer certifies a given pairing as a basic model, an assurance is provided to DOE that the rating, based on the basic model pair, represents the
maximum flush volume that the basic model pair is designed to provide.

Therefore, in this final rule, DOE retains the existing definition of basic model for water closets and urinals, and incorporates by reference section 7.1.5.2 of ASME A112.19.2–2008, which clearly
states that a flushometer valve must be connected to the test bowl and specifies that while conducting the water consumption test for water closets, the valve is required to maintain a peak flow rate. However, because the addition of new items to the existing reporting requirements requires separate review that is not being conducted as part of this rulemaking, DOE declines to adopt the requirement that the flushometer valve used during the water consumption testing of water closets
and urinals be included on the certification report, and will address that proposal as part of a separate rulemaking. F. Statistical Sampling Plans

In the May 2012 NOPR, DOE requested comment on the provisions of the statistical sampling plans for faucets, showerheads, water closets, urinals, and commercial prerinse spray valves specified in 10 CFR sections 429.28, 429.29, 429.30, 429.31, and 429.51, including the confidence limits and potential revisions to the respective sampling plans that might better reflect the level of repeatability that is
achievable for each test. 77 FR 31746 (May 30, 2012). Moen, PMI, Kohler, Sloan Valve, and AWE all supported retaining the existing statistical sampling plans and no dissenting comments were received. (Moen, No. 4 at p. 4; PMI, No. 8 at pp. 4–5; Kohler, No. 9 at p. 4; Sloan Valve, No. 12 at p. 3; AWE, No. 13 at p. 3) Therefore, in this final rule DOE retains the existing statistical sampling plans without change.

G. Information To Be Provided in Certification Reports

In the May 2012 NOPR, DOE proposed to retain the existing general reporting requirements as they are listedin 10 CFR 429.12, as well as productspecific requirements in 10 CFR 429.28 (for faucets), 429.29 (for showerheads), 429.30 (for water closets), 429.31 (for urinals), and 429.51 (for commercial prerinse spray valves). DOE also proposed to move the rounding provisions for all five products to 10 CFR part 429 to clarify that rounding of
the final rated value of water consumption for a basic model should occur after application of the sampling

statistics. 77 FR 31749. No comments were received in response to this proposal.

In the April 2013 SNOPR, DOE proposed to change the certification requirements in 10 CFR 429.30(b)(2) for water closets and 429.31(b)(2) for urinals to require manufacturers to identify in their certification reports the flushometer valve used during the water consumption test. 78 FR 20839. Under this proposal, the flushometer valve listed on the certification report must represent the flush volume of the water closet and urinal if used with any other valve with the same flush volume rating or less, and must represent the maximum design flush volume of the
water closet or urinal.

PMI and IAPMO commented that there was no objection to the reporting of the flushometer valve used during testing provided there was no implication that only the test valve
listed could be used with each tested water closet bowl or urinal body. (PMI,


### 62982 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

No. 23 at p. 6; IAPMO, No. 25 at p. 2) No comments were received opposing the proposal to require reporting of the flushometer valve used during testing in certification reports.

Based on the comments received, DOE intends to adopt a requirement for the flushometer valve used during the water consumption testing of water
closets and urinals to be included on the certification report. However, because the addition of new items to the existing reporting requirements requires separate review that is not being conducted as part of this rulemaking, DOE is not adopting this requirement in this final rule and will revisit this proposal as part of a future rulemaking.

H. Changes in Measured Water Use

In any rulemaking to amend a test procedure, DOE must determine to what extent, if any, the proposed test procedure would alter the measured energy efficiency or energy use, or, in the case of this rulemaking, water use, of any covered product as determined under the existing test procedure. (42 U.S.C. 6293(e)(1)) If DOE determines that the amended test procedure would
alter the measured water use of a covered product, DOE must amend the applicable water conservation standard accordingly. (42 U.S.C. 6293(e)(2))

In this final rule, DOE incorporates by reference updated versions of ASME A112.18.1–2012, test procedure for faucets and showerheads; ASME A112.19.2–2008, test procedure for water closets and urinals; and ASTM F2324–09, test procedure for prerinse spray valves. The updated industry standards incorporate minor adjustments in test methodology, such as changes in temperatures and
inclusion of instrument tolerances that were not previously specified and, DOE has determined, do not alter the measured water consumption.

In addition, the final rule adds rounding instructions for certification reporting requirements for measures of water use for these products. Similarly, the addition of the rounding instructions for certification reporting
does not affect the measured water consumption.

Therefore, based on a consideration of the above, DOE determines that the amended test procedure would not alter
the measured water use of a covered product and that revisions to the water
conservation standards due to the amended test procedure are not warranted under 42 U.S.C. 6293(e)(2). IV. Procedural Issues and Regulatory

Review

A. Review Under Executive Order 12866

The Office of Management and Budget has determined that test procedure rulemakings do not constitute ‘‘significant regulatory actions’’ under section 3(f) of Executive Order 12866, ‘‘Regulatory Planning and Review.’’ 58 FR 51735 (Oct. 4, 1993). Accordingly, this action was not subject to review under the Executive Order by the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget (OMB).

B. Review Under the Regulatory Flexibility Act

The Regulatory Flexibility Act (5

U.S.C. 601 et seq. ) requires preparation of an initial regulatory flexibility analysis (IRFA) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a
substantial number of small entities. As required by Executive Order 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ 67 FR 53461 (August 16, 2002), DOE published procedures and policies on February 19, 2003 to ensure that the potential impacts of its rules on small entities are properly considered during the DOE rulemaking process. 68 FR at 7990. DOE has made its procedures and policies
available on the Office of the General

DOE reviewed the amendments to the test procedures for plumbing equipment including showerheads, faucets, water closets, urinals and commercial prerinse spray valves under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. DOE certifies that the
amendments would not result in significant economic impacts on small
entities. The factual basis for this
certification is set forth in this rulemaking.

For the plumbing equipment manufacturing industry, the Small Business Administration (SBA) has set a size threshold, which defines those
entities classified as ‘‘small businesses’’ for the purpose of the statute. DOE used
the SBA’s size standards to determine whether any small entities would be required to comply with the rule. The
size standards are codified at 13 CFR part 121. The standards are listed by North American Industry Classification System (NAICS) code and industry description and are available at www.sba.gov/idc/groups/public/
documents/sba

_homepage/serv

_ sstd

_ tablepdf.pdf . Plumbing equipment
manufacturers are classified under NAICS 332913, ‘‘Plumbing Fixture Fitting and Trim Manufacturing,’’ and NAICS 327111, ‘‘Vitreous China Plumbing Fixture and China and
Earthenware Bathroom Accessories Manufacturing.’’ The SBA sets a threshold of 500 employees or less for NAICS 332913, and 750 employees or less for NAICS 327111, for an entity to
be considered a small business within these categories.

DOE conducted a focused inquiry into
small business manufacturers of products covered by this rulemaking. During its market survey, DOE used all available public information to identify potential small manufacturers. DOE’s research involved the review of industry trade association membership directories (including the American Society of Plumbing Engineers), product databases ( e.g., Federal Trade Commission (FTC), the Thomas Register ® , California Energy Commission (CEC), and ENERGY STAR databases), individual company Web sites, and marketing research tools ( e.g., Dun and Bradstreet reports, and Manta) to create a list of companies that manufacture or sell plumbing products covered by this rulemaking. Using these sources, DOE identified 83 manufacturers of showerheads, faucets, water closets, urinals, and commercial prerinse spray valves.

DOE then reviewed this data to
determine whether the entities met the
SBA’s definition of a small business manufacturer of covered plumbing products and screened out companies that do not offer products covered by this rulemaking, do not meet the definition of a ‘‘small business,’’ or are foreign owned and operated. Based on this review, DOE has identified 48
manufacturers that would be considered
small businesses that would be affected by this rulemaking. Through this analysis, DOE determined the expected impacts of the rule on affected small
businesses and whether an IRFA was needed ( i.e., whether DOE could certify that this rulemaking would not have a significant economic impact on a substantial number of small entities).

Table IV.1 stratifies the small businesses according to their number of employees. The smallest company has 4 employees and the largest company 375 employees. The majority of the small businesses affected by this rulemaking (88 percent) have fewer than 100 employees. Annual revenues associated
with these small manufacturers were estimated at $492.5 million ($10.3


### 62983 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

million average annual sales per small manufacturer). According to DOE’s analysis, small entities constitute 58 percent of the entire plumbing equipment manufacturing industry covered by the rule.

As noted in the Background and Summary sections (I and II) of this rule, EPCA requires that DOE review its test procedures for covered products at least once every 7 years and to amend them if the Secretary determines that to do so would provide test procedures that would more accurately or completely
measure water use and that are not unduly burdensome to conduct. (42 U.S.C. 6293(b)(1)) To comply with EPCA, this rule incorporates amendments to ASME test procedures, which have been updated for faucets, showerheads, water closets and urinals. Additionally, EPCA prescribes use of
the ASTM standard F2324 for commercial prerinse spray valves, which is a product that is also covered in this rulemaking.

Showerheads and Faucets

DOE is updating its test procedures for showerheads and faucets by incorporating by reference AMSE
standard A112.18.1–2012. These incorporated changes involve minor adjustments in test methodology, such as changes in temperatures and
inclusion of instrument tolerances that were not previously specified, none of which would require any additional equipment and are not expected to lengthen the time required to complete the test. Because there are no major changes in testing the test procedures, calculation methodology or certification requirements associated with these amendments, DOE has determined there is no incremental cost burden to small entities associated with this change.

Water Closets and Urinals

DOE is updating its water closet and urinal test procedures from those set
forth in ASME/ANSI standard
A112.19.6–1995 to ASME standard A112.19.6–2008. The changes involve minor adjustments in test setup, the specification of certain instrumentation tolerances, and minor adjustment to test pressures, none of which would require additional equipment or lengthen the time required to complete the test. Because there are no major changes in the test procedures or requirements for these products, DOE incorporates this change by reference. The changes adopted in this rule will not alter current testing procedures, calculation methodologies, or enforcement. Therefore, DOE has concluded there is
no incremental cost burden to small
manufacturers associated with the nonsubstantive changes in this rule.

Commercial Prerinse Spray Valves

DOE currently requires that commercial prerinse spray valves be tested according to the ASTM ‘‘Standard Test Method for Prerinse Spray Valves’’ (ASTM F2324–03). This rule does not make any alterations to this test, as it has not been updated since the 2003 version that DOE incorporated in the CFR. 70 FR 60407 (Oct. 18, 2005). Thus,
DOE determines there is no incremental
cost burden to manufacturers of commercial prerinse spray valves
associated with this rule.

As indicated in the discussion
associated with small business listed in Table IV.1, DOE has analyzed the manufacturing industry for showerheads, faucets, water closets, urinals, and commercial prerinse spray
valves and has determined that 58 percent of all plumbing equipment
manufacturers could be classified as small entities according to the SBA classification. Although 58 percent of the market is a significant portion of the overall industry, these manufacturers would not be significantly affected by
this rule because there are no incremental costs to any entity due to its implementation. In the absence of potential cost impacts, the rule by
definition would not have disproportionate effects on small
businesses.

Based on the criteria outlined above, DOE has determined that the proposed testing procedure amendments would not have a ‘‘significant economic impact
on a substantial number of small entities,’’ and the preparation of an
IRFA is not warranted. DOE will transmit the certification and supporting
statement of factual basis to the Chief Counsel for Advocacy of the Small
Business Administration for review under 5 U.S.C. 605(b).

C. Review Under the Paperwork Reduction Act of 1995

Manufacturers of showerheads, faucets, water closets, urinals, and


### 62984 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

commercial prerinse spray valves must certify to DOE that their products comply with any applicable water conservation standards. In certifying compliance, products must be tested according to the DOE test procedures for showerheads, faucets, water closets, urinals, and commercial prerinse spray valves, including any amendments adopted for those test procedures. DOE has established regulations for the certification and recordkeeping requirements for all covered consumer products and commercial equipment, including showerheads, faucets, water closets, urinals, and commercial prerinse spray valves. 76 FR 12422(March 7, 2011). The collection-ofinformation requirement for the certification and recordkeeping is subject to review and approval by OMB under the Paperwork Reduction Act (PRA). Public reporting burden for the certification is estimated to average 20 hours per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection
of information.

Notwithstanding any other provision of the law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the PRA, unless that collection of information displays a currently valid OMB Control Number. This requirement has been approved by
OMB under OMB control number 1910–

1400.

D. Review Under the National Environmental Policy Act of 1969

In this final rule, DOE amends its test procedure for showerheads, faucets, water closets and urinals to improve the ability of DOE’s procedures to more accurately account for the water consumption of these products. DOE
has determined that this rule falls into a class of actions that are categorically
excluded from review under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq. ) and DOE’s implementing regulations at 10 CFR part 1021. Specifically, this rule amends an existing rule without affecting the amount, quality, or distribution of water usage, and, therefore, will not result in any environmental impacts. Thus, this rulemaking is covered by Categorical Exclusion A5 under 10 CFR part 1021, subpart D, which applies to any rulemaking that interprets or amends an existing rule without changing the
environmental effect of that rule. Accordingly, neither an environmental assessment nor an environmental impact statement is required.

E. Review Under Executive Order 13132

Executive Order 13132, ‘‘Federalism,’’ 64 FR 43255 (August 4, 1999) imposes certain requirements on agencies formulating and implementing policies or regulations that preempt State law or that have Federalism implications. The Executive Order requires agencies to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and to carefully assess the necessity for such actions. The Executive Order also requires agencies to have an accountable process to ensure meaningful and timely input by
State and local officials in the development of regulatory policies that have Federalism implications. On March 14, 2000, DOE published a statement of policy describing the intergovernmental consultation process it will follow in the development of such regulations. 65 FR at 13735. DOE
examined this final rule and determined
that it will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. EPCA governs and prescribes Federal preemption of State regulations as to energy conservation for the products that are the subject of this final rule. States can petition DOE for exemption from such preemption to the extent and according to criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further action is required by Executive Order 13132.

F. Review Under Executive Order 12988

Regarding the review of existing regulations and the promulgation of new regulations, section 3(a) of Executive Order 12988, ‘‘Civil Justice Reform,’’ 61 FR 4729 (Feb. 7, 1996), imposes on Federal agencies the general duty to adhere to the following requirements: (1) Eliminate drafting errors and ambiguity; (2) write regulations to minimize litigation; (3) provide a clear legal standard for affected conduct rather than a general standard; and (4) promote simplification and burden reduction. Section 3(b) of Executive Order 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation: (1) Clearly specifies the preemptive effect, if any; (2) clearly specifies any effect on existing Federal law or regulation; (3) provides a clear legal standard for affected conduct while promoting simplification and burden reduction; (4) specifies the retroactive effect, if any; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under any guidelines issued by the Attorney General. Section 3(c) of Executive Order 12988 requires Executive agencies to review regulations in light of applicable standards in sections 3(a) and 3(b) to determine whether they are met or it is
unreasonable to meet one or more of them. DOE has completed the required review and determined that, to the extent permitted by law, this final rule
meets the relevant standards of
Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments and the private sector. Pub. L. 104–4, 201 (codified at 2 U.S.C. 1531). For a regulatory action resulting in a rule that may cause the expenditure by State, local, and Tribal governments, in the aggregate, or by the private sector of $100 million or more in any one year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish a written statement that estimates the resulting costs, benefits,
and other effects on the national economy. (2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to develop an effective process to permit timely input by elected officers of State, local, and Tribal governments on a proposed ‘‘significant intergovernmental mandate,’’ and requires an agency plan for giving notice and opportunity for timely input to potentially affected small governments before establishing any requirements that might significantly or uniquely affect small governments. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental
consultation under UMRA. 62 FR 12820; also available at http://www.gc.doe.gov/gc/office-generalcounsel . DOE examined this final rule according to UMRA and its statement of policy and determined that the rule contains neither an intergovernmental mandate, nor a mandate that may result in the expenditure of $100 million or more in any year, so these requirements do not apply.

H. Review Under the Treasury and General Government Appropriations
Act, 1999

Section 654 of the Treasury and General Government Appropriations Act, 1999 (Pub. L. 105–277) requires


### 62985 Federal Register / Vol. 78, No. 205 / Wednesday, October 23, 2013 / Rules and Regulations

Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well-being. This final rule will not have any impact on the autonomy or integrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking

Assessment.

I. Review Under Executive Order 12630

DOE has determined, under Executive Order 12630, ‘‘Governmental Actions and Interference with Constitutionally Protected Property Rights,’’ 53 FR 8859 (March 18, 1988), that this regulation will not result in any takings that might require compensation under the Fifth
Amendment to the U.S. Constitution.

J. Review Under Treasury and General Government Appropriations Act, 2001

Section 515 of the Treasury and General Government Appropriations Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines established by each agency pursuant to general guidelines issued by OMB. OMB’s guidelines were published at 67 FR 8452 (Feb. 22, 2002), and DOE’s guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has reviewed
this final rule under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines.

K. Review Under Executive Order 13211

Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use,’’ 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to OMB, a Statement of Energy Effects for any significant energy action. A ‘‘significant energy action’’ is defined as any action by an agency that promulgated or is expected to lead to promulgation of a final rule, and that: (1) Is a significant regulatory action under Executive Order 12866, or any successor order; and (2) is likely to have a significant adverse effect on the supply, distribution, or use of energy; or (3) is designated by the Administrator of OIRA as a significant energy action. For any significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use if the regulation is implemented, and of
reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use.

This regulatory action is not a significant regulatory action under Executive Order 12866. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy, nor has it been designated as a significant energy action by the Administrator of OIRA. Therefore, it is not a significant energy action, and, accordingly, DOE has not prepared a Statement of Energy Effects.

L. Review Under Section 32 of the Federal Energy Administration Act of

1974

Under section 301 of the Department of Energy Organization Act (Pub. L. 95– 91; 42 U.S.C. 7101), DOE must comply with section 32 of the Federal Energy Administration Act of 1974 (FEAA), as amended by the Federal Energy
Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA) Section 32 essentially provides in relevant part that, where a proposed rule authorizes or requires use of commercial standards, the notice of proposed rulemaking must inform the public of the use and background of such standards. In addition, section 32(c) requires DOE to consult with the Attorney General and
the Chairman of the Federal Trade Commission (FTC) concerning the impact of the commercial or industry standards on competition.

The modifications to the test procedures addressed by this action incorporate testing methods contained
in section 5.4 of commercial standard ASME A112.18.1–2012 and sections 7.1,

7.1.1, 7.1.2, 7.1.3, 7.1.4, 7.4, 8.2, 8.2.1, 8.2.2, 8.2.3, 8.6, Table 5, and Table 6 of
commercial standard ASME A112.19.2–
2008. DOE has evaluated these two
versions of these standards and is unable to conclude whether they fully comply with the requirements of section 32(b) of the FEAA ( i.e., whether they were developed in a manner that fully provides for public participation, comment, and review.) DOE has consulted with both the Attorney
General and the Chairman of the FTC about the impact on competition of using the methods contained in these
standards and has received no comments objecting to their use.

M. Congressional Notification

As required by 5 U.S.C. 801, DOE will report to Congress on the promulgation
of this rule before its effective date. The report will state that it has been determined that the rule is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

■ 11. Appendix T to subpart B of part 430 is amended by adding a note after the appendix heading; and revising section 2, ‘‘Test Apparatus and General Instructions,’’ and section 3, ‘‘Test Measurement,’’ to read as follows:

Appendix T to Subpart B of Part 430— Uniform Test Method for Measuring the Water Consumption of Water Closets
and Urinals

Note: After April 21, 2014, any representations made with respect to the water consumption of water closets or urinals
must be made in accordance with the results of testing pursuant to this appendix.

Manufacturers conducting tests of water closets or urinals after November 22, 2013 and prior to April 21, 2014, must conduct

a. The test apparatus and instructions for testing water closets shall conform to the requirements specified in section 7.1, General, subsections 7.1.1, 7.1.2, 7.1.3, 7.1.4,
and 7.1.5 of ASME A112.19.2–2008 (incorporated by reference, see § 430.3). The
flushometer valve used in the water consumption test shall represent the maximum design flush volume of the water
closet. Measurements shall be recorded at the
resolution of the test instrumentation. Calculations of water consumption for each
tested unit shall be rounded off to the same number of significant digits as the previous step.

b. The test apparatus and instructions for testing urinals shall conform to the requirements specified in section 8.2, Test Apparatus and General Instructions, subsections 8.2.1, 8.2.2, and 8.2.3 of ASME A112.19.2–2008 (incorporated by reference,

see § 430.3). The flushometer valve used in the water consumption test shall represent the maximum design flush volume of the
urinal. Measurements shall be recorded at the
resolution of the test instrumentation. Calculations of water consumption for each
tested unit shall be rounded off to the same number of significant digits as the previous step.

3. Test Measurement

a. Water closets: (i) The measurement of the water flush volume for water closets, expressed in gallons per flush (gpf) and liters per flush (Lpf), shall be conducted in accordance with the test requirements specified in section 7.4, Water Consumption Test, of ASME A112.19.2–2008 (incorporated by reference,

see § 430.3). For dual-flush water closets, the
measurement of the water flush volume shall be conducted separately for the full-flush and
reduced-flush modes and in accordance with the test requirements specified section 7.4, Water Consumption Test, of ASME

A112.19.2–2008.

(ii) Static pressure requirements: The water consumption tests of siphonic and blowout
water closets shall be conducted at two static pressures. For flushometer valve water closets with a siphonic bowl, the test pressures shall be 80 psi and 35 psi. For
flushometer valve water closets with a blowout bowl, the test pressures shall be 80 psi and 45 psi. The test shall be run three times at each pressure as specified in section 7.4.3 ‘‘Procedure,’’ of ASME A112.19.2–2008 (incorporated by reference, see § 430.3). The
final measured flush volume for each tested unit shall be the average of the total flush volumes recorded at each test pressure as specified in section 7.4.5 ‘‘Performance,’’ of

ASME A112.19.2–2008.

(iii) Flush volume and tank trim component adjustments: For gravity flush tank water closets, trim components that can be adjusted to cause an increase in flush volume, including (but not limited to) the flapper valve, fill valve, and tank water level, shall be set in accordance with the printed installation instructions supplied by the
manufacturer. If the installation instructions for the model to be tested do not specify trim setting adjustments, these trim components shall be adjusted to the maximum water use setting so that the maximum flush volume is produced without causing the water closet to
malfunction or leak. The water level in the
tank shall be set to the maximum water line designated in the printed installation instructions supplied by the manufacturer or the designated water line on the tank itself, whichever is higher. If the printed
installation instructions or the water closet tank do not indicate a water level, the water level shall be adjusted to 1 ± 0.1 inches below the top of the overflow tube or 1 ± 0.1 inches below the top rim of the water-containing vessel (for gravity flush tank water closets that do not contain an overflow tube) for each designated pressure specified in Table 5 of ASME A112.19.2–2008 (incorporated by reference, see § 430.3).

b. Urinals—The measurement of water flush volume for urinals, expressed in gallons per flush (gpf) and liters per flush (Lpf), shall
be conducted in accordance with the test requirements specified in section 8.6, Water Consumption Test, of ASME A112.19.2–2008 (incorporated by reference, see § 430.3). The
final measured flush volume for each tested unit shall be the average of the total flush volumes recorded at each test pressure as specified in section 8.6.4 ‘‘Performance,’’ of

ASME A112.19.2–2008.

■ 12. Section 430.32 is amended by revising paragraph (p) to read as
follows:

**§ 430.32 Energy and water conservation**
**standards and their effective dates.**

* * * * * (p) Showerheads. The maximum water use allowed for any showerheads manufactured after January 1, 1994, shall be 2.5 gallons per minute (9.5 liters per minute) when measured at a flowing pressure of 80 pounds per square inch gage (552 kilopascals). When used as a component of any such showerhead, the flow-restricting insert shall be mechanically retained at the point of manufacture such that a force of 8.0 pounds force (36 Newtons) ormore is required to remove the flowrestricting insert, except that this requirement shall not apply to
showerheads for which removal of the flow-restricting insert would cause water to leak significantly from areas other than the spray face.

I. Background

The American Energy Manufacturing Technical Corrections Act (AEMTCA; H.R. 6582), Public Law 112–210, was signed into law on December 18, 2012. Among its provisions are amendments

to Part B 1 of Title III of the Energy Policy and Conservation Act of 1975 (EPCA or ‘‘the Act’’) (42 U.S.C. 6291– 6309, as codified), which provides for an energy conservation program for consumer products other than automobiles, and to Part C 2 of Title III of EPCA (42 U.S.C. 6311–6317, as codified), which provides for an energy conservation program for certain commercial and industrial equipment,
similar to the one in Part B for consumer products. 3 Some of the AEMTCA
amendments to EPCA establish or modify certain energy conservation standards and related definitions, and make technical changes to the Act.
Other AEMTCA amendments to EPCA prescribe criteria for the conduct of rulemakings to promulgate energy
conservation standards for various consumer products and commercial and industrial equipment, or direct the Department of Energy (DOE) to undertake rulemakings under EPCA.

By this action, DOE is including in the Code of Federal Regulations (CFR)
the new and modified standards and definitions, and certain of the technical changes, prescribed by the AEMTCA. DOE is also making additional changes to the language of its regulations that are necessitated by certain statutory language contained in AEMTCA’s new
and revised standards and definitions. This is a purely technical amendment, and at this time DOE is not exercising
