2012-12919. Energy Conservation Program for Consumer Products and Certain Commercial and Industrial Equipment: Test Procedures for Showerheads, Faucets, Water Closets, Urinals, and Commercial Prerinse Spray Valves

AGENCY:

Office of Energy Efficiency and Renewable Energy, Department of Energy.

ACTION:

Notice of proposed rulemaking and public hearing.

SUMMARY:

In this notice of proposed rulemaking (NOPR), the U.S. Department of Energy (DOE) proposes to update its test procedures for showerheads, faucets, water closets, and urinals. Specifically, DOE proposes to incorporate by reference the American Society of Mechanical Engineers/American National Standards Institute (ASME/ANSI) Standard A112.18.1-2011 test procedure for faucets and showerheads, which would replace the 1996 version currently referenced by DOE in its test procedure. DOE also proposes to incorporate by reference ASME/ANSI Standard A112.19.2-2008 procedure for water closets and urinals, which would replace the 1995 version currently referenced by DOE in its test procedure. These updates fulfill DOE's obligation under the Energy Policy and Conservation Act (EPCA) to review its test procedures for covered products at least once every 7 years and either amend the applicable test procedures or publish a determination in the Federal Register not to amend them. DOE also expects that incorporation of the updated procedures will bring DOE's testing requirements more closely in line with current industry practices, reduce the burden associated with testing and reporting test results for these products, and improve the accuracy of test results.

For commercial prerinse spray valves, DOE has preliminarily determined that no changes are needed to the existing DOE test procedure in order to accurately measure the water consumption of these products, and proposes to retain the existing procedure without change. However, since the American Society for Testing and Materials (ASTM) reapproved this standard in 2009 as F2324-03 (2009), DOE is proposing to incorporate by reference this most recent version. This action would also satisfy the EPCA requirement for DOE to review the test procedures for these products at least once every 7 years.

This notice also announces a public meeting to receive comments on these proposed amendments to the test procedures.

DATES:

DOE will hold a public meeting on July 24, 2012, from 9 a.m. to 4 p.m., in Washington, DC. The meeting will also be broadcast as a webinar.

I. Background and Authority

Title III, Part B of the Energy Policy and Conservation Act of 1975 (EPCA), Public Law 94-163 (42 U.S.C. 6291-6309, as codified), established the Energy Conservation Program for Consumer Products Other Than Automobiles, which includes the showerheads, faucets, water closets, and urinals that are the subjects of today's notice.^[1]

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

EPCA also includes a water conservation standard and test procedure for commercial prerinse spray valves, which are also addressed in this notice. While commercial prerinse spray valves were originally referenced in Part B of EPCA, DOE noted in a final rule published October 18, 2005, that placement of commercial prerinse spray valves in Part B rather than part C of EPCA, which established the Energy Conservation Program for Certain Commercial and Industrial Equipment,^[2] was the result of a legislative drafting error, and subsequently adopted the provisions for commercial prerinse spray valves into 10 CFR part 431. 70 FR 60407, 60409.

General Test Procedure Rulemaking Process

In 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, in relevant part, 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 of Energy (Secretary) determines that this requirement would impose an undue burden. (42 U.S.C. 6293(c)(3))

II. Summary of the Notice of Proposed Rulemaking

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)) DOE last amended test procedures for these products in a final rule published in March 1998 (March 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/ANSI has revised both procedures and issued the most recent versions as A112.18.1-2011, “Plumbing Supply Fittings,” for showerheads and faucets in June 2011, and A112.19.2-2008, “Ceramic Plumbing Fixtures,” for water closets and urinals in August 2008.

In today's notice, DOE proposes to amend its existing test procedures for showerheads, faucets, water closets, and urinals by adopting, with the exception of certain provisions regarding rounding of measured values, the most recent versions of the corresponding ASME/ANSI procedures for measuring the water consumption of these products. DOE has evaluated these industry procedures and has preliminarily determined that the revised ASME/ANSI test procedures for showerheads, faucets, water, closets, and urinals would (1) produce test results that more accurately measure water use during a representative average use cycle or period of use; and (2) not be unduly burdensome to conduct. 42 U.S.C. 6293(b)(1), (3). DOE has also determined that the adoption of these revised procedures would not alter the measured water use of these products. DOE's determination that the measured water use of showerheads, faucets, water closets, and urinals is not altered is based on an evaluation of the changes to the procedures described in Section III.A for each of the covered products.

Section 135(b)(1) of EPACT 2005 amended section 323(b) of EPCA (42 U.S.C. 6293(b)) to add subsection (14), which states that test procedures 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 Pre-Rinse Spray Valves.' ” In a final rule published on December 8, 2006, DOE incorporated by reference the 2003 version of ASTM Standard F2324 in 10 CFR 431.263, and established it as the uniform test method for measurement of the flow rate of commercial prerinse spray valves in section 431.264. 71 FR 71340.

While commercial prerinse spray valves are included in Part B of EPCA as consumer products rather than in Part C, which addresses commercial and industrial equipment, DOE notes that Part C also contains the same provision regarding periodic review of test procedures for covered equipment at least once every seven years. 42 U.S.C. 6314(a)(1)(A). To fulfill this statutory requirement, DOE initiated this rulemaking and proposes in this NOPR to amend its test procedures for commercial prerinse spray valves. Specifically, DOE proposes to update its references in DOE's current test procedures to the latest version of the ASTM Standard by incorporating by reference ASTM Standard F2324-03 (2009), “Standard Test Method for Prerinse Spray Valves.”

The two statutory provisions that address representative test results and test burden for consumer products, which are discussed in the previous paragraph, also apply to DOE review of the test procedures for commercial and industrial equipment. 42 U.S.C. 6314(a)(2). In this light, DOE has evaluated ASTM F2324-03(2009), “Standard Test Method for Prerinse Spray Valves,” and has preliminarily determined that these two provisions are met. ASTM F2324-03(2009) does not involve any substantive amendment to the current DOE test procedure for commercial prerinse spray valves, which is based on ASTM F2324-03. However, to reflect the reapproval of the F2324-03 standard by ASME in 2009, DOE is proposing to incorporate by reference the reapproved version in 10 CFR 431.264.

DOE also proposes to retain the existing descriptors for measures of maximum permissible water use for water closets, urinals, faucets, and showerheads currently found in 10 CFR 430.23(s) through 430.23(v) (gallons or liters per minute or cycle, and gallons or liters per flush), and to retain the existing water use descriptors (gallons or liters per minute) for commercial prerinse spray valves in 10 CFR 431.264.

DOE considers the activity initiated by this proposed rule sufficient to satisfy the statutory requirement that DOE must review its test procedures for all covered products, including plumbing products, at least once every 7 years and either amend the applicable test procedures or publish a determination in the Federal Register not to amend them. (42 U.S.C. 6293(b)(1)(A) and 42 U.S.C. 6314(a)(1))

III. Discussion

A. Statutory Plumbing Requirements

1. Test Procedures for Showerheads and Faucets

The current test procedures for showerheads and faucets are found in appendix S of 10 CFR part 430, subpart B, (Appendix S) and require that tests be conducted in accordance with the test procedure requirements specified in section 6.5, “Flow Capacity Test,” of ASME/ANSI Standard A112.18.1M-1996. In the revised ASME/ANSI Standard A112.18.1-2011, the flow capacity test has been moved to section 5.4 of that standard, titled “Flow Rate.” Minor substantive changes to the flow capacity test include (1) a requirement that the pressure differential measurement be within ±1 pound per square inch (psi) for faucets and ±2 psi for showerheads (not previously specified for either product), (2) a change in the test procedure temperature range to 5 to 71 °C for faucets (previously 4 to 66 °C) and to 32 to 44 °C for showerheads (previously 4 to 66 °C), (3) a requirement that a container large enough to hold water collected over a minimum of 1 minute be used when using the time/volume test procedure method for faucets and showerheads (not previously specified), and (4) a requirement that flow be maintained during testing for at least 1 minute for showerheads (not previously specified). DOE sees no evidence that the changes identified in this paragraph will result in a change in the measured water use of faucets or showerheads, and therefore proposes to incorporate by reference the applicable section of ASME/ANSI Standard A112.18.1-2011 for testing showerheads and faucets at Appendix S.

The existing test procedure language in Appendix S of 10 CFR part 430 also requires, for all faucets and showerheads, that measurements be recorded at the resolution of the test instrumentation and that calculations be rounded off to the same number of significant digits as the previous step. It also requires that the final water consumption value be rounded to one decimal place for non-metered faucets and for showerheads, and to two decimal places for metered faucets. DOE originally introduced these provisions as part of its 1998 final rule in order to establish uniformity in the calculated results reported in certifications of compliance. 63 FR at 13310. DOE has not received any information since that time indicating that these rounding provisions should be modified, and proposes to retain them without change.

DOE requests comment on these proposed amendments to the existing test procedures for showerheads and faucets, including provisions pertaining to representations of water consumption and calculations of those values.

2. Test Procedures for Water Closets and Urinals

The current test procedure for water closets and urinals is found in appendix T of 10 CFR part 430, subpart B, (Appendix T) and incorporates by reference ASME/ANSI Standard A112.19.6-1995. The test procedure in Appendix T is divided into two sections: “Test Apparatus and General Instructions,” and “Test Measurement,” both of which reference corresponding provisions in A112.19.6-1995. When ASME merged ASME/ANSI Standard A112.19.6-1995 with ASME/ANSI Standard A112.19.2-2003 “Vitreous China Plumbing Fixtures” to produce ASME/ANSI Standard A112.19.2-2008, several sections of the water consumption tests for water closets and urinals that DOE refers to in Appendix T were renumbered and no longer correspond to the same sections DOE references.

a. Test Procedure for Water Closets

DOE proposes to amend its regulations to correspond to the changes that ASME made in the 2008 version of its procedures for water closets. Specifically, the existing DOE test procedure in Appendix T requires that the test apparatus and instructions for testing water closets conform to the requirements specified in section 7.1.2, “Test Apparatus and General Instructions,” subsections 7.1.2.1, 7.1.2.2, and 7.1.2.3, of ASME/ANSI Standard A112.19.6-1995, whereas DOE now proposes that its test procedure reference ASME/ANSI Standard A112.19.2-2008, and in particular the sections that specify the requirements for test apparatus instructions and instructions for testing water closets in 7.1.1, 7.1.2, 7.1.3, and 7.1.4. These sections include minor changes to the test setup, which are described in the next paragraph.

The existing DOE test procedure requires that the measurement of the water flush volume of water closets be conducted in accordance with the test requirements specified in ASME/ANSI Standard A112.19.6-1995, section 7.1.6, “Water Consumption and Hydraulic Characteristics.” In the updated ASME/ANSI A112.19.2-2008, the test procedure for measuring the water flush volume of water closets is found in section 7.4, “Water Consumption Test.” Dual-flush water closets, which are not addressed in the 1995 ASME/ANSI procedure or in DOE's current test procedure, are required under ASME/ANSI A112.19.2-2008 ^[3] to meet the flush volume requirement for low consumption water closets of 1.6 gallons per flush when the full flush volume is activated. Additional minor updates found in ASME/ANSI A112.19.2-2008 include (1) a required filter in the apparatus set-up (not previously required), (2) required receiving vessel calibration in increments of 0.25 liters (0.07 gallons) (decreased from 0.1 gallons), (3) required use of an electric timer with increments that are accurate within a tenth of a second to verify that the actuator is held for a maximum of 1 second (not previously specified), (4) revised static pressure requirements for flushometer valves with siphonic bowls to 80 psi for one round of tests and 35 psi for the second two rounds (previously one round of tests at each of three pressures: 80, 50, and 15 psi) and a similar provision for flushometer valves with blowout bowls, but at 80 and 45 psi (previously 80, 50, and 35 psi), and (5) required rounding of the total flush volume down to the nearest 0.25 liters (0.07 gallons) (not previously specified). DOE sees no evidence that the changes identified in this paragraph will result in a change in the measured water use of water closets, would produce test results that less accurately measure the water use of water closets during a representative average use cycle, or would be more burdensome to conduct, and therefore proposes to incorporate by reference the applicable sections of ASME/ANSI Standard A112.19.2-2008 for testing water closets into Appendix T, except the rounding provisions, as discussed in section III.A.2.c.

b. Test Procedure for Urinals

The current DOE test procedure for urinals is also found in Appendix T and incorporates by reference ASME/ANSI Standard A112.19.6-1995. The existing DOE test procedure requires that the test apparatus and instructions for testing urinals conform to the requirements specified in ASME/ANSI Standard A112.19.6-1995, section 8.2, “Test Apparatus and General Instructions,” subsections 8.2.1, 8.2.2, and 8.2.3. In updated ASME/ANSI Standard A112.19.2-2008, the section that specifies the requirements for test apparatus instructions and instructions for testing urinals is 8.2, “Test Apparatus and General Instructions,” which includes subsections 8.2.1, 8.2.2, and 8.2.3. The existing DOE test procedure requires that the measurement of the water flush volume of urinals be conducted in accordance with the test requirements specified in ASME/ANSI A112.19.6-1995, section 8.5, “Water Consumption.” In the 2008 version of A112.19.2, these requirements have been moved to section 8.6, “Water Consumption Test.” Additionally, minor updates to the water consumption test found in ASME/ANSI A112.19.2-2008 include (1) a required filter in the apparatus set-up (not previously specified), (2) required receiving vessel calibration of 0.25 liters (0.07 gallons) (decreased from 0.1 gallons), and (3) required rounding of the total flush volume down to the nearest 0.25 liters (0.07 gallons) (not previously specified). DOE sees no evidence that the changes identified in this paragraph will result in a change in the measured water use of urinals, produce test results that less accurately measure the water use of urinals during a representative average use cycle, or would be more burdensome to conduct, and therefore proposes to incorporate by reference the applicable sections from ASME/ANSI Standard A112.19.2-2008 for testing urinals into Appendix T, except for the rounding provision, as discussed in section III.A.2.c.

c. Rounding of Test Results for Water Closets and Urinals

For both urinals and water closets, the existing DOE test procedure language in Appendix T requires that measurements be recorded at the resolution of the test instrumentation; that calculations be rounded off to the same number of significant digits as the previous step; and that the final water consumption value be rounded to one decimal place for water closets and for urinals. DOE added these provisions in its 1998 final rule (63 FR 13310-11) and has not received any information since that time indicating that these rounding provisions should be modified. However, in order to maintain consistency with the measurement and calculation methods in the ASME/ANSI A112.19.2-2008 procedure, DOE proposes to amend the rounding provisions in Appendix T to require that the final value of water consumption for each tested unit retain the number of significant digits present in the measured test value. Because EPCA uses gallons as the primary unit of measurement for assessing compliance with the standards for these products, the test values for each model would be converted to gallons after applying the applicable sample statistics in 10 CFR 429.30 or 429.31, and the rated value of water consumption rounded to the nearest 0.01 gallon per flush (or nearest 0.01 liter per flush).

d. Dual-Flush Water Closets

As previously discussed, DOE is proposing to require that dual-flush water closets be tested according to ANSI/ASME Standard A112.19.2-2008 to determine their maximum flush volume, as observed in full flush mode. However, DOE is aware that other testing and reporting metrics have been developed for these products in order to reflect the reduction in average water consumption that results from use of the reduced flow mode. In particular, the Environmental Protection Agency (EPA) WaterSense program's ^[4] specifications for water closets permit the overall water consumption of dual-flush water closets to be represented as a weighted average of the flush volumes, in which it is assumed that two thirds of all flushes will be the reduced flow (see EPA WaterSense Specification for Tank-Type Toilets version 1.1, section 3.2, available at http://www.epa.gov/​WaterSense/​docs/​revised_​het_​specification_​v1.1_​050611_​final508.pdf,, or DOE Docket Number EERE-2011-BT-TP-0061, No. 1, p. 1).

DOE is proposing a test procedure to measure the water use of a dual-flush water closet over a representative average period of consumer use (“average representative water use”). DOE may, in a future rulemaking, consider amendments to the certification provisions for water closets that could account for the impact of the reduced flush on the water consumption of dual-flush water closets.

Under the proposed test procedure, the flush volume of the reduced flush would be measured using section 7.4 of ASME/ANSI Standard A112.19.2-2008 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.

In order to ensure that DOE has considered all relevant aspects of this approach, DOE requests comments on (1) its proposal to develop a test procedure to measure the average representative water use of dual-flush water closets in general, (2) whether the use of a composite average of the flush volumes of a dual-flush water closet is representative of the average water use of these products, and (3) whether the specific ratio of flush volumes proposed in this notice (i.e., two reduced flushes and one full flush) is an appropriate measure of the representative average water use of dual-flush water closets.

DOE requests comment on these proposed amendments to the existing test procedures for water closets and urinals, including provisions pertaining to representations of water consumption and calculations of those values, and the appropriate means of determining the representative average water use of dual-flush water closets.

3. Test Procedure for Commercial Prerinse Spray Valves

The current DOE test procedure for commercial prerinse spray valves is found in section 431.264 of 10 CFR part 431, subpart O, and requires that the test procedure to determine the water consumption flow rate of commercial prerinse spray valves be conducted in accordance with the test requirements specified in sections 4.1 and 4.2 (Summary of Test Method), 5.1 (Significance and Use), 6.1 through 6.9 (Apparatus) except 6.5, 9.1 through 9.5 (Preparation of Apparatus), 10.1 through 10.2.5 (Procedure), and calculations in accordance with sections 11.1 through 11.3.2 (Calculation and Report) of ASTM F2324-03, “Standard Test Method for Prerinse Spray Valves.” ASTM has not updated the portions of this ASTM standard that are referenced in the DOE test procedure since DOE incorporated this standard by reference in the December 2008 final rule. 71 FR 71340. After considering that ASTM reapproved this standard in 2009 without making any substantive changes, DOE proposes in this NOPR to amend its current test procedure by incorporating by reference the most recent version of this standard as ASTM Standard F2324-03 (2009), “Standard Test Method for Prerinse Spray Valves.”

The existing DOE test procedure for commercial prerinse spray valves found at 10 CFR 431.264 requires that measurements be recorded at the resolution of the test instrumentation; that calculations be rounded off to the same number of significant digits as in the previous step; and that the final water consumption value be rounded off to one decimal place as follows: (1) a fractional number at or above the midpoint between two consecutive decimal places shall be rounded up to the higher of the two decimal places, or (2) a fractional number below the midpoint between two consecutive decimal places shall be rounded down to the lower of the two decimal places. DOE proposes to retain these provisions without change.

DOE invites comments on its proposal to retain the existing test procedure for commercial prerinse spray valves, with incorporation by reference of the most recent version of the ASTM standard, and is interested in any views on the suitability of this procedure for meeting the requirements of EPCA with respect to representativeness of measurements and test burden.

4. Design Requirements for Showerheads

In addition to the water consumption standards that were promulgated by EPCA for showerheads, the statute includes a provision that showerheads must also meet the requirements of section 7.4.3(a) of ASME/ANSI A112.18.1M-1989, 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 pounds (8 lbf.) or more is required to remove the insert. DOE subsequently adopted this provision in 10 CFR 430.32(p).

In the March 1998 final rule that adopted ASME/ANSI A112.18.1M-1996 as the test procedure for showerheads and faucets, DOE amended the text in section 430.32(p) to reflect that the aforementioned provision of the ASME/ANSI standard had been moved to section 7.4.4(a). 63 FR 13309-10. This provision was retained in the updated A112.18.1-2011, but has been moved to section 4.11.1 of that standard. Additionally, the language for this provision in the 2011 version of the ASME standard has changed slightly from the 1996 version in that the force required to remove the flow-restricting insert is no longer referred to specifically as a “pushing or pulling” force, but rather, is described only as a force of 36 Newtons (N) (8.0 lbf) or more, where the Newton measurement represents a conversion of the original lbf measurement to the International System of Units (SI, or metric units) after rounding to a whole number. Since the amount of force expressed in inch/pound units has not changed, DOE does not view this as a substantive change in the industry requirement and proposes to incorporate the text of this provision from ASME/ANSI Standard A112.18.2-2011 at section 430.32(p) of 10 CFR part 430 as a direct replacement of the existing provision. However, for the purposes of compliance with Federal standards, DOE proposes to retain the 8 lbf metric as the applicable standard in order to maintain consistency with the original statutory provision in 42 U.S.C. 6295(j), which references the 8 lbf requirement as described in the first paragraph of this section. Thus, the proposed text lists 8 lbf as the primary measure, with the equivalent 36 N included as a secondary metric for reference purposes.

While DOE is not proposing any change to this design requirement, DOE notes that no specific test procedure exists in ASME Standard A112.18.1-2011, or in any previous version of that standard, for verifying that a flow-restricting insert remains mechanically retained when subjected to a force of 8 lbs. DOE searched for a more general test method for assessing a pulling or pushing force of this type and was unable to identify any standardized method for this purpose. One of the testing organizations DOE contacted did provide information about the types of test configurations and equipment it typically uses for assessing compliance with this requirement during the compliance tests for showerheads, which generally apply either a pushing or pulling force that is measured using a calibrated force meter. However, since the design configuration of flow-restricting inserts varies among models, a standardized method based upon the setups currently used by test laboratories may not be useful in all cases, particularly if a flow-restricting insert is a threaded screw-in type, wherein a torque would be required to remove it as opposed to a pulling or pushing force. Other flow-restricting inserts are secured to the inlet of the showerhead with a retainer or plastic plate that requires the testing laboratory to adapt its test depending on the specific location of the flow-restricting insert and retainer.

In the absence of any publicly available standard test method, and with limited information about how variation in the designs of flow-restricting inserts may complicate the development of a standardized method, DOE is unable at this time to propose, for inclusion in the test procedure for showerheads, a specific method of verifying the force required to remove a flow-restricting insert. However, since the adoption of a standardized approach would enable manufacturers to more effectively demonstrate compliance with this provision in the case of a challenge and would enable DOE or others to independently verify compliance in a standardized manner, DOE is interested in receiving comments and information on prospective methods for verifying that the 8 lbf requirement in section 4.11.1 of ASME/ANSI Standard A112.18.1-2011 has been met. DOE is also interested in comments and information on showerhead designs that may complicate verification of this provision or make it unnecessary. Based upon information received, DOE may consider proposing a test method as part of a supplemental notice of proposed rulemaking.

5. Definitions

To address certain provisions of the revised ASME/ANSI procedures that were not contemplated in the versions referenced by the existing DOE test procedure, and to establish greater clarity with respect to product coverage, DOE proposes to adopt new definitions for the terms “accessory,” “body spray,” and “fitting,” based on the definitions for these components in ASME/ANSI Standard A112.18.1-2011, and a definition for “dual-flush water closet” from ASME/ANSI Standard A112.19.2-2008, all of which would be incorporated into 10 CFR part 430, section 430.2. DOE also proposes a definition for “hand-held showerhead,” which is not found in ASME/ANSI A112.18.1-2011, but was derived from the description of these products found in the WaterSense Specification for Showerheads, Version 1.0, developed by the EPA (See http://www.epa.gov/​WaterSense/​docs/​showerheads_​finalspec508.pdf,, or DOE Docket Number EERE-2011-BT-TP-0061, No. 2, p. 1). Finally, DOE proposes an amendment to the existing definition of “showerhead” currently found in 10 CFR 430.2. The proposed definition is based upon the definition for showerhead included in ASME/ANSI A112.18.1-2011, but has been modified to more clearly define the extent of DOE's coverage of these products, and to specifically state that safety shower showerheads are not covered products, that hand-held showerheads are covered, and that DOE considers a body spray to be a showerhead for the purposes of regulatory coverage.

DOE also notes that the proposed application of the terms “fitting” and “accessory” to showerheads, specifically within the context of their coverage under DOE standards, may diverge slightly from previous use of these terms in other DOE documents addressing these products. DOE is proposing to adopt definitions for fitting and accessory, and a definition of showerhead that uses these terms, in order to more closely align the regulatory terminology with that of the industry standards upon which the DOE test procedure and water conservation standards are based, and to ensure that the meanings of these terms are consistent as applied to the products covered by DOE standards.

All components that are defined as an “accessory” (or a combined set of accessories) to a supply fitting represent a single covered product that must meet the DOE standard. Any components that are part of the “fitting” that is supplying water to an accessory, such as a valve (or valves) and connected piping, are not part of the covered product. Because the applicable water conservation standard applies to a basic model of a covered product as distributed in commerce, individual basic models that are packaged and sold, or otherwise distributed in commerce, separately and installed into a system by the purchaser would be subject to the standard individually, not as an installed system. In contrast, a system of spraying components that is packaged and/or distributed in commerce as a single “accessory” or a single set of “accessories,” designed to be attached to a single fitting, would be defined as a single showerhead and would be subject to the 2.5 gallon per minute (gpm) standard assigned to these products under 42 U.S.C. 6295(j).

DOE invites comments on its proposal to adopt definitions for “accessory,” “body spray,” “hand-held showerhead,” “fitting,” and “dual-flush water closet,” and to amend the definition of “showerhead” as shown in the proposed regulatory text at the end of this notice.

B. Supplementary Plumbing Requirements

1. Definition of a Basic Model

DOE defines a “basic model” as it applies to showerheads, faucets, water closets, and urinals in 10 CFR 430.2, and it defines “basic model” as it applies to commercial prerinse spray valves in section 431.262. With respect to the definitions of “basic model” as they apply to showerheads, faucets, and commercial prerinse spray valves, DOE has received no information since the adoption of these definitions indicating that a revision is necessary, and does not propose any revisions to these definitions in this proposed rule.

With respect to water closets and urinals, DOE has received information indicating that confusion may exist among manufacturers regarding how to properly apply the concept of a basic model to certain types of water closets and urinals. More specifically, in the case of flushometer valve water closets and urinals,^[5] and certain gravity tank water closets in which the tank and flushing device are concealed within the wall rather than attached directly to the bowl, DOE has been made aware that the water consumption of a given model of bowl for a water closet or urinal can be directly affected by the specific flushometer valve or tank-type flushing device that is paired with that bowl. This has complicated the process of testing, reporting, and labeling water closets and urinals under the existing DOE compliance, certification, and enforcement provisions due to the various combinations of valves and/or tanks from different manufacturers that could be paired with a given bowl.

DOE proposes to retain the existing definitions of a basic model of water closet and basic model of urinal, but emphasizes that the manner in which individual models may be grouped together as basic models for the purposes of reporting water consumption in accordance with 10 CFR 429.12 should be based upon the maximum flow for a given bowl (or urinal body) and the valve or tank with which it is designed to operate. In other words, by certifying a given pairing of water closet bowl and valve (or tank) or urinal body and valve as a basic model under the existing certification and compliance framework, the manufacturer would be certifying that the pairing on which that basic model's rating is based is the maximum flush volume that model of water closet bowl or urinal body is designed to provide, and that it could not be paired with a flushing device or tank that would provide a higher flush volume and still function properly.

Under the compliance certification framework described in the previous paragraph, a manufacturer would be permitted to represent the rated flush volume of a particular model of water closet bowl or urinal body using a representative model of flushometer valve or gravity tank that provides a flush volume at this maximum level, regardless of any other such pairings that may be possible using valves or tanks from other manufacturers. Since, by design, none of the individual models of that basic model of water closet or urinal could operate using a flushing device providing a higher volume, the pairing upon which the certification is based, as well as all other pairings, would be compliant with the applicable water consumption standard. In addition, manufacturers are permitted under the certification provisions of 10 CFR part 429 to rate products conservatively at the maximum flush volume, even if certain combinations of bowls and flushing devices consume less water per flush than the maximum volume permitted by the relevant water consumption standard. Note, however, that if a manufacturer wishes to make representations of the water consumption of a given pairing that provides a lower volume flush than the maximum design volume, such as on product labels or in advertising or marketing materials, that particular pairing must be certified as a separate basic model and rated at the specific flush volume that the manufacturer intends to use in representations.

As a theoretical example of this method, a manufacturer wishes to certify a particular model of flushometer water closet, referred to here as “model A.” This model is designed to operate using flushometer valves that provide a volume as high as 1.6 gallons per flush (the Federal standard), and as low as 1.28 gallons per flush (the EPA WaterSense standard). There are many available flushometer valves that meet these requirements, but the manufacturer has tested model A with two flushometer valves: model 1, which operates at 1.6 gallons per flush, and model 2, which operates at 1.28 gallons per flush. The individual model pairings are identified as models A1 and A2, respectively. If the manufacturer is not concerned about labeling this model at any rating less than the Federal standard, then it is permissible to rate the model using valve model 1, and certify model A at 1.6 gallons per flush. To indicate that the basic model can use multiple flush valves, under this model numbering convention it could be certified as basic model A*, with the asterisk as a placeholder value to allow for other valve models. However, if the manufacturer wishes to label a version of model A as meeting the 1.28 gallon per flush standard, the combination that provides that rating must be certified separately as basic model A2.

DOE invites comments on this interpretation of the current definition of a basic model of water closet and urinal, and any other factors that DOE should consider in clarifying the definition of basic model and how manufacturers may group models and rate their water consumption.

2. Statistical Sampling Plans for Certification

The statistical sampling plans required for determining the rated values of water consumption for faucets, showerheads, water closets, urinals, and commercial prerinse spray valves are specified in sections 429.28, 429.29, 429.30, 429.31, and 429.51, respectively, of 10 CFR part 429. While DOE is not proposing to change these provisions in today's NOPR, DOE is interested in receiving comments on all elements of these provisions, including the confidence limits and potential revisions to the respective sampling plans that might better reflect the level of repeatability and reproducibility that is achievable for each test, and the variability in measured water consumption that is inherent for each product.

3. Information To Be Provided in Certification Reports

10 CFR part 429 describes the information that manufacturers are required to supply to DOE to certify that covered products comply with energy and water conservation standards. Section 429.12 lists the information that manufacturers are required to report for all products, and specific requirements for plumbing products are identified in section 429.28 (for faucets), section 429.29 (for showerheads), section 429.30 (for water closets), section 429.31 (for urinals), and section 429.51 (for commercial prerinse spray valves). DOE proposes to retain the existing reporting requirements for all five product types. DOE proposes to move the rounding provision for the rated value of water consumption for all five product types from the applicable test procedures to 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.

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Order 12866

The Office of Management and Budget (OMB) 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 proposed action was not subject to review under the Executive Order by the Office of Information and Regulatory Affairs (OIRA) in the 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 proposed rule, 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, so that the potential impacts of its rules on small entities are properly considered during the rulemaking process. 68 FR 7990 (February 12, 2003). DOE has made its procedures and policies available on the Office of the General Counsel's Web site at http://www.gc.doe.gov/​gc/​office-general-counsel.

DOE reviewed the proposed rule to amend 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 proposed rule, if adopted, would not result in significant economic impacts on small entities. The factual basis for this certification is set forth in the following paragraphs.

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

Total	48

As noted in the Summary and Background sections of this NOPR, EPCA requires that DOE review its test procedures for covered products at least once every seven 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. (See 42 U.S.C. 6293(b)(1)) To comply with EPCA, this rule proposes to incorporate amendments to ASME/ANSI 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 proposing to update its testing procedures for showerheads and faucets by incorporating by reference AMSE/ANSI Standard A112.18.1-2011. These proposed 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 procedures, calculation methodology or certification requirements associated with this proposal, DOE has tentatively determined there would be no incremental cost burden to small entities associated with this change.

Water Closets and Urinals

DOE is proposing to update its water closet and urinal test procedures from those set forth in ASME/ANSI A112.19.6-1995 to comply with ASME/ANSI A112.19.6-2008. The proposed 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 testing procedures or requirements for these products, DOE proposes to incorporate this change by reference. The changes proposed in this rule would not alter current testing procedures, calculation methodologies or enforcement. Therefore, DOE has tentatively concluded there would be no incremental cost burden to small manufacturers associated with the non-substantive changes in this proposed 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 proposed rule would not make any alterations to this test, as it has not been updated since the 2003 version that DOE incorporated in the Code of Federal Regulations. 70 FR 60407 (October 18, 2005). Thus, DOE determines there would be no incremental cost burden to manufacturers of commercial prerinse spray valves associated with this proposed rule.

As indicated previously, 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 would be no incremental costs to any entity due to its implementation. In the absence of potential cost impacts, the proposed rule by definition would not have disproportionate effects on small businesses.

Based on the criteria outlined in the preceding paragraph, DOE has tentatively concluded 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).

DOE seeks comment on its tentative conclusion that the proposed test procedure changes will not have a significant impact on a substantial number of small entities.

C. Review Under the Paperwork Reduction Act of 1995

Manufacturers of showerheads, faucets, water closets, urinals, and commercial prerinse spray valves must certify to DOE that their products comply with any applicable water conservation standards. In certifying compliance, manufacturers must test their products 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-of-information requirement for the certification and recordkeeping is subject to review and approval by OMB under the Paperwork Reduction Act (PRA). This requirement has been approved by OMB under OMB control number 1910-1400. 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.

D. Review Under the National Environmental Policy Act of 1969

In this notice, DOE proposes to amend 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 changing its environmental effect, and, therefore, is covered by the Categorical Exclusion in 10 CFR part 1021, subpart D, paragraph A5. The exclusion applies because this rule would establish revisions to existing test procedures that would not affect the amount, quality, or distribution of energy usage, and, therefore, would not result in any environmental impacts. Accordingly, neither an environmental assessment nor an environmental impact statement is required.

E. Review Under Executive Order 13132

Executive Order 13132, “Federalism,” imposes certain requirements on agencies formulating and implementing policies or regulations that preempt State law or that have Federalism implications. 64 FR 43255 (August 10, 1999). 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 that it will follow in developing such regulations. 65 FR 13735. DOE examined this proposed rule and determined that it would 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 proposed rule. States can petition DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. (42 U.S.C. 6297) 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,” 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. 61 FR 4729 (Feb. 7, 1996). Section 3(b) of Executive Order 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation specifies the following: (1) the preemptive effect, if any; (2) any effect on existing Federal law or regulation; (3) a clear legal standard for affected conduct while promoting simplification and burden reduction; (4) the retroactive effect, if any; (5) definitions of key terms; and (6) 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 whether 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 proposed 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) (Pub. L. 104-4; 2 U.S.C. 1501 et seq.) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments and the private sector. For a proposed regulatory action likely to result 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 estimates of the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a)-(b)) 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 such governments. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA. 62 FR 12820. (The policy is also available at http://www.gc.doe.gov/​gc/​office-general-counsel.) This proposed rule contains neither an intergovernmental mandate nor a mandate that may result in an 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 Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well-being. This proposed rule would 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 proposed regulation would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution.

J. Review Under the 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 proposed rule under 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 the Office of Information and Regulatory Affairs (OIRA) a Statement of Energy Effects for any proposed significant energy action. A “significant energy action” is defined as any action by an agency that promulgates 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 proposed significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use if the proposal is implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use.

This proposed regulatory action to amend the test procedures for measuring the water consumption of showerheads, faucets, water closets, and urinals is not a significant regulatory action under Executive Order 12866. It has likewise not been designated as a significant energy action by the Administrator of OIRA. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy. 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 DOE Organization Act (Pub. L. 95-91; 42 U.S.C. 7101 et seq.), DOE must comply with section 32 of the Federal Energy Administration Act of 1974, as amended by the Federal Energy Administration Authorization Act of 1977 (FEAA). (15 U.S.C. 788) Section 32 essentially provides in part that, where a proposed rule authorizes or requires use of commercial standards, the rulemaking must inform the public of the use and background of such standards. In addition, section 32(c) requires DOE to consult with the U.S. Attorney General (Attorney General) and the Chairman of the Federal Trade Commission (FTC) concerning the impact of the commercial or industry standards on competition.

The proposed modifications to the test procedures addressed by this proposed action incorporate testing methods contained in section 5.4 of commercial standard ASME/ANSI Standard A112.18.1-2011 and sections 7.1.1, 7.1.2, 7.1.3, 7.1.4, 7.4, 8.2.1, 8.2.2, 8.2.3, and 8.6 of commercial standard ASME/ANSI Standard A112.19.2-2008. DOE has evaluated 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 will consult with the Attorney General and the Chairman of the FTC about the impact on competition of using the methods contained in these standards, before prescribing a final rule.

E. Issues on Which DOE Seeks Comment

Although DOE welcomes comments on any aspect of this proposal, DOE is particularly interested in receiving comments and views of interested parties concerning the following issues:

1. DOE requests comment on its proposal to incorporate by reference ASME/ANSI Standard A112.18.1-2011, “Plumbing Supply Fittings,” specifically regarding the following substantive changes to the current DOE test procedures for showerheads and faucets: (1) A requirement that the pressure differential measurement be within +/^ 1 pound per square inch (psi) for faucets and +/^ 2 psi for showerheads (not previously specified for either product), (2) a change in the test procedure temperature range to 5 to 71 °C for faucets (previously 4 to 66 °C) and to 32 to 44 °C for showerheads (previously 4 to 66 °C), (3) required use of a container large enough to hold water collected over a minimum of 1 minute when using the time/volume test procedure method (not previously specified), and (4) a requirement that flow be maintained for at least 1 minute for showerheads (not previously specified).

2. DOE requests comment on the proposed incorporation by reference of the ASME/ANSI Standard A112.19.2-2008, “Ceramic Plumbing Fixtures,” specifically regarding the following substantive changes to the current test procedures for water closets and urinals: (1) A required filter in the apparatus set-up (not previously required), (2) receiving vessel calibration of 0.25 liters (0.07 gallons) (decreased from 0.1 gallons), (3) required use of an electric timer with increments that are accurate to within a tenth of a second to verify the actuator is held for a maximum of 1 second (not previously specified), (4) change in the static pressure requirements for a flushometer valve with a siphonic bowl to 80 and 35 psi (previously 80, 50, and 15 psi) and with blowout bowl to 80 and 45 psi (previously 80, 50, and 35 psi), and (5) requiring rounding of the calculated value for each tested unit to the number of significant digits resulting from the test in place of the 0.25 liter increment in the revised ANSI/ASME standard.

3. DOE requests comments on (1) its proposal to develop a test procedure to measure the average representative water use of dual-flush water closets in general, (2) whether the use of a composite average of the flush volumes of a dual-flush water closet is representative of the average water use of these products, and (3) whether the specific ratio of flush volumes proposed in this notice (i.e., two reduced flushes and one full flush) is an appropriate measure of the representative average water use of dual-flush water closets.

4. DOE requests comment on its proposal to retain the existing test procedure for commercial prerinse spray valves and incorporate by reference the most recent version of ASTM F2324-03. DOE is also interested in any views on the suitability of this procedure for meeting the requirements of EPCA with respect to representativeness of measurements and test burden.

5. DOE requests comments and information on prospective methods for verifying that the 8 lb. force requirement in section 4.11.1 of ASME/ANSI Standard A112.18.1-2011 has been met, and any showerhead designs that may complicate verification of the 8 lb. force provision or make it unnecessary.

6. DOE requests comment on its proposed definitions of the terms “accessory,” “body spray,” “fitting,” “hand-held showerhead,” and “dual-flush water closet,” and its proposed amendment to the existing definition of “showerhead.”

7. DOE requests comment on the current definition of a basic model of water closet and urinal and any other factors that DOE should consider in determining the appropriate means by which to group various combinations of water closet or urinal bowls with flushing devices as basic models and rate their water consumption.

8. DOE requests comment on all elements of the provisions for the calculation of test results, including the confidence limits; revisions to the sampling plans that might better reflect the level of precision that is achievable for each respective test; and variability in measured water consumption that is expected for each respective product.

9. DOE seeks comment on its tentative conclusion that the proposed test procedure changes will not have a significant impact on a substantial number of small entities.
