The U.S. Department of Energy (DOE) proposes to revise its test procedures and certification reporting requirements for commercial clothes washers established under the Energy Policy and Conservation Act. The proposed amendments provide numerical equations for translating modified energy factor and water factor values as measured using DOE's new clothes washer test procedure into their equivalent values as measured using the current test procedure. The proposed amendments also clarify the dates for which the current and new test procedures can be used to determine compliance with existing energy conservation standards and any future revised energy conservation standards for commercial clothes washers.
DOE will accept comments, data, and information regarding this notice of proposed rulemaking (NOPR) no later than April 28, 2014 See section V, “Public Participation,” for details. DOE will hold a public meeting on this proposed test procedure if one is requested by February 26, 2014.

Title III of the Energy Policy and Conservation Act of 1975 (42 U.S.C. 6291, et seq; “EPCA”), Public Law 94-163, 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, Pub. L. 112-210 (Dec. 18, 2012)). Part C of title III, which for editorial reasons was re-designated as Part A-1 upon incorporation into the U.S. Code (42 U.S.C. 6311-6317, as codified), establishes the “Energy Conservation Program for Certain Industrial Equipment.” The program includes commercial clothes washers, the subject Start Printed Page 8113of today's proposed rulemaking. (42 U.S.C. 6311(1)(H))
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 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.
The Energy Policy Act of 2005 (EPACT) established the first energy conservation standards for commercial clothes washers. (42 U.S.C. 6313(e)(1)) EPACT directed DOE to conduct two rulemakings to determine whether the established standards should be amended. DOE published its first final rule amending commercial clothes washer standards on January 8, 2010 (“January 2010 final rule”), which applies to commercial clothes washers manufactured on or after January 8, 2013. EPACT required the second final rule to be published by January 1, 2015. Any amended standards would apply to commercial clothes washers manufactured three years after the date on which the final amended standard is published. (42 U.S.C. 6313(e)(2)(B)) DOE is currently conducting its second standards rulemaking to satisfy this requirement.[1]
The commercial clothes washer standards established by the January 2010 final rule are based on energy and water metrics as measured using the DOE test procedure for both residential and commercial clothes washers at 10 CFR part 430, subpart B, appendix J1 (“appendix J1”). On March 7, 2012, DOE published a final rule amending its test procedures for clothes washers (“March 2012 final rule”). (77 FR 13888) The March 2012 final rule included minor amendments to appendix J1 and also established a new test procedure at 10 CFR part 430, subpart B, appendix J2 (“appendix J2”). Beginning March 7, 2015, manufacturers of residential clothes washers will be required to use appendix J2 to demonstrate compliance with standards. Beginning March 7, 2015, manufacturers of commercial clothes washers may use either appendix J1 or appendix J2 to demonstrate compliance with the current standards established by the January 2010 final rule. Manufacturers using appendix J2 would be required to use the conversion equations proposed in this NOPR to translate the measured efficiency metrics into equivalent appendix J1 values. The use of appendix J2 would be required to demonstrate compliance with any amended energy conservation standards to be published in a final rule by January 1, 2015, and the conversion equations would no longer be used at that time.
In today's proposed rule, DOE proposes to amend its test procedure and certification reporting requirements for commercial clothes washers as described in section II. Under 42 U.S.C. 6314, 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 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. 6314(a)(2))
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. 6314(b)(2))
In this NOPR, DOE proposes amending its test procedure and certification reporting requirements for commercial clothes washers by adding equations for translating modified energy factor (MEF) and water factor (WF) values as measured using appendix J2 into their equivalent values as measured using appendix J1. This translation would be required for manufacturers that make representations of energy efficiency (including representations in certification reports) based on testing conducted in accordance with appendix J2 before the effective date of any amended standards to be published in a final rule by January 1, 2015.
DOE also proposes to amend the definitions for commercial clothes washers in 10 CFR 430.152 to clarify the nomenclature used to differentiate the energy and water efficiency metrics in appendix J1 and appendix J2, as applicable to commercial clothes washers.
Finally, DOE also responds to comments from interested parties regarding the commercial clothes washer test procedure that DOE received in response to the framework document and public meeting for the energy conservation standards rulemaking for commercial clothes washers.[2]
As described in section I, the March 2012 final rule established a new test procedure at appendix J2, which is required to be used for residential clothes washers beginning March 7, 2015, to demonstrate compliance with amended energy conservation standards for residential clothes washers. Beginning March 7, 2015, manufacturers of commercial clothes washers may also use appendix J2 to demonstrate compliance with current energy conservation standards for commercial clothes washers.
Both appendix J1 and appendix J2 contain provisions for calculating MEF and WF. In today's rule, DOE proposes to provide numerical equations for translating the MEF and WF values calculated using appendix J2 into their equivalent appendix J1 values. Manufacturers would be required to use these equations when testing pursuant to the appendix J2 test procedure to demonstrate compliance with the current commercial clothes washer standards, which are based on MEF and WF values as measured using appendix J1. DOE also proposes new designations for the appendix J2 metrics: (1) MEFJ2, defined as the modified energy factor value calculated in section 4.5 of appendix J2, and (2) WFJ2, defined as the water factor value calculated in section 4.2.12 of appendix J2. These new metric designations would be codified at 10 CFR 431.152. The translation equations would be codified within the certification requirements at 10 CFR 429.46(b). DOE also proposes to amend section 429.46 to clarify that beginning March 7, 2015, manufacturers may use either appendix J1 or, alternatively, appendix J2 in conjunction with the proposed translation equations, to demonstrate compliance with existing energy Start Printed Page 8114conservation standards for commercial clothes washers. Appendix J2 would be required to demonstrate compliance with any amended standards based on appendix J2 efficiency metrics, and the conversion equations would not be used at that time.
The proposed equations for translating MEF and WF values measured under appendix J2 to equivalent appendix J1 values were obtained as described in the discussion that follows.
DOE tested a representative sample of top-loading commercial clothes washers currently on the market to determine the MEF and WF equations. Data from DOE's tests are shown in Figure 1 and Figure 2 below. DOE's test sample included baseline models that minimally comply with the existing standards as well as higher-efficiency models that span the available range of efficiencies on the market. Due to the relatively small number of models currently available on the market, DOE supplemented its test sample with models manufactured before the amended standards became effective on January 8, 2013.[3] DOE observed that the MEF translations for top-loading commercial clothes washers are closely correlated with the type of water fill control system.[4] Therefore, DOE proposes separate MEF equations for each water fill control system type. DOE proposes a single WF equation for all top-loading commercial clothes washers because DOE has not observed any significant difference in WF translation between manual and automatic [5] water fill control system types. Figure 1 and Figure 2 show the MEF and WF translation curves, respectively. The proposed equations are as follows, where MEFJ2 and WFJ2 are the values of modified energy factor and water factor, respectively, obtained using appendix J2:
(i) MEF for top-loading commercial clothes washers with manual water fill: MEF = (MEFJ2 × 1.53) − 0.14
(ii) MEF for top-loading commercial clothes washers with automatic water fill: MEF = (MEFJ2 × 1.09) + 0.15
(iii) WF for all top-loading commercial clothes washers: WF = (WFJ2 × 0.81) +1.33
Start Printed Page 8115
DOE tested a representative sample of front-loading commercial clothes washers currently on the market to determine the MEF and WF equations. Data from DOE's tests are shown in Figure 3 and Figure 4 below. DOE's test sample included baseline models that minimally comply with the existing standard as well as higher-efficiency models that span the available range of efficiencies on the market. As with the top-loading commercial clothes washers, due to the relatively small number of models currently available on the market, DOE supplemented its front-loading test sample with models manufactured before the amended standards became effective on January 8, 2013. DOE proposes a single equation for both MEF and WF for all front-loading commercial clothes washers because all front-loading commercial clothes washers on the market use automatic water fill controls. Figure 3 and Figure 4 show the MEF and WF translation curves, respectively. The crosswalk equations are as follows:
(i) MEF = (MEFJ2 × 1.13) + 0.14
(ii) WF = WFJ2

In response to the framework document and public meeting for the energy conservation standards rulemaking for commercial clothes washers, DOE received comments from interested parties regarding the test procedure. DOE responds to those comments in the discussion that follows.
The Association of Home Appliance Manufacturers (AHAM) proposed that DOE not require the use of appendix J2 for compliance with commercial clothes washer standards until such time as DOE requires compliance with amended standards. AHAM stated that it understands the stated reasoning for requiring manufacturers to transition to appendix J2 in March 2015 but questioned whether it is necessary to require that transition prior to amended standards for commercial clothes washers. (AHAM, No. 6 at p. 2) [6]
Alliance Laundry Systems (ALS) supports allowing the continued use of appendix J1 from March 7, 2015, until the effective date of any amended 2018 standards. ALS asserted that that any Start Printed Page 8117existing basic model currently in production must still be valid after any test procedure change. (ALS, Public Meeting Transcript, No. 12 at pp. 25-26; ALS, No. 16 at p. 1).
Pacific Gas and Electric Company, Southern California Gas Company, and San Diego Gas and Electric Company (collectively, the “California Utilities”) support DOE's proposal to develop correction factors that would become effective for current standards on March 7, 2015, when the new appendix J2 test procedure takes effect, because the new test procedure is different than the previous appendix J1 test procedure. (California Utilities, No. 8 at pp. 1-2)
DOE has established both appendix J1 and appendix J2 as test procedures for clothes washers. Manufacturers of residential clothes washers must use appendix J2 to demonstrate compliance with the amended standards for residential clothes washers, which were developed using appendix J2, on March 7, 2015. Consistent with EPCA requirements at 42 U.S.C. 6314(a)(8), DOE proposes to allow manufacturers of commercial clothes washers to use either appendix J1 or, alternatively, appendix J2 in conjunction with the proposed translation equations, to demonstrate compliance with existing energy conservation standards, which are based on appendix J1. The use of appendix J2 would be required to demonstrate compliance with any amended standards for commercial clothes washers to be published in a final rule by January 1, 2015, which would be based on appendix J2 metrics.
The Appliance Standards Awareness Project (ASAP) suggested that the residential clothes washer test procedure could contain a separate section containing procedures applicable only to commercial clothes washers. (ASAP, Public Meeting Transcript, No. 12 at p. 37)
The Northwest Energy Efficiency Alliance (NEEA) commented that DOE should consider further investigation and possible modification of the test procedure to accurately reflect commercial clothes washer typical usage patterns. NEEA stated that commercial clothes washers are often used in a different manner than residential clothes washers; for example, commercial clothes washers are often subject to larger load sizes and are not generally used to wash small loads due to fixed costs to wash a load. NEEA believes that by reflecting accurate appliance usage in the test procedure, the standards would achieve greater energy savings in the field. (NEEA, No. 10 at p. 2)
DOE received more specific comments on these issues, and responds to them in the paragraphs that follow.
Section 4.3 of appendix J2 provides the calculation of per-cycle energy consumption for removal of moisture from the test load (i.e., the drying energy), which is one of the energy components used to calculate MEF. The drying energy is calculated as the product of: (1) the weighted average load size; (2) the remaining moisture content minus 4%; (3) the dryer usage factor of 0.91; and (4) the DEF, the nominal energy required for a clothes dryer to remove moisture from clothing, defined as 0.5 kWh/lb.
Southern Company commented that the test procedure should incorporate a variable DEF, stating that the energy used for drying clothes in a dryer is not an automated process, and is highly dependent on consumer behavior. Southern Company believes that the current DEF factor of 0.5 kWh/lb appears to assume perfect operation and efficiency of drying, and suggests that DOE should determine reasonable values for the clothes dryer energy for both residential and commercial clothes dryers, which are likely to be different, and then use a weighted average value for variable DEF and any other relevant energy factors. (Southern Company, No. 9 at pp.1-2). Furthermore, Southern Company commented that the Electric Power Research Institute has performed metering of residential clothes washers and dryers in real-life situations, and preliminary findings indicate very little dryer energy savings from reduced moisture content in the clothes washers. (Southern Company, Public Meeting Transcript, No. 12 at p. 24) Southern Company suggests that DOE make assumptions about the percentage in the market of features such as dryer moisture sensors and incorporate those into the test procedure. (Southern Company, Public Meeting Transcript, No. 12 at p. 36)
The National Resources Defense Council and Appliance Standards Awareness Project (NRDC and ASAP) jointly commented that DOE should consider the prevalence of timer-activated termination controls in commercial dryers. The commenters stated that the energy savings in commercial clothes washers achieved by reducing the remaining moisture content of clothing at the end of the wash cycle is largely dependent on moisture-sensing termination controls in commercial dryers. NRDC and ASAP cited a 2009 report on residential clothes dryers that found that termination control strategies can vary in effectiveness and that actual dryer energy varied by 20-30 percent for the same load, largely because energy use at the end of cycle is not being captured in the current dryer test procedure. (NRDC and ASAP, No. 11 at p. 2) NRDC also commented that it is more common for commercial dryers to be operated on a time-dry basis rather than a moisture sensing basis. NRDC believes DOE should collect data on the existing stock of dryers in the commercial setting, and the availability of a sensor dry feature in today's stock of commercial dryers. (NRDC, Public Meeting Transcript, No. 12 at pp. 26-27)
The calculation of drying energy in the clothes washer test procedure is intended to provide a nominal estimate of associated drying energy that can be used to distinguish among clothes washer models that provide varying degrees of remaining moisture in the clothing load, to provide a consistent basis of comparison applied across all types of clothes washers. In addition, DOE does not have consumer usage data that would indicate how consumer usage of commercial clothes dryers might differ from residential clothes dryers. DOE also does not have data indicating the prevalence of features in commercial clothes dryers such as moisture sensors that would affect the drying times. Such data would be required to support any changes in the test procedure calculations.
Section 4.1.3 of appendix J2 provides the calculation of total weighted per-cycle hot water energy consumption (i.e., the water heating energy), which is one of the energy components used to calculate MEF. The water heating energy calculations assume a 100% efficient electric water heater that provides a water heating value of 0.00240 kWh/gal/°F. Section 4.1.4 of the test procedure also provides a conversion for gas water heating, assuming a gas water heater efficiency of 75%. However, the gas water heating calculation is not used in the calculation of MEF or WF.
Southern Company commented that these water heater efficiencies are reasonable assumptions, but should be updated as the weighted efficiency of installed water heaters changes over time, as electric heat pump water heaters and gas condensing water heaters gain market share. Southern Company further noted that these assumptions are reasonable because water heater energy usage is not Start Printed Page 8118dependent on consumer behavior, but is an automatic process. (Southern Company, No. 9 at pp. 1-2)
DOE recognizes that the household water heater market includes a wide variety of water heater types at different efficiency levels and using different fuel sources. DOE notes, however, that the calculation of water heating energy in the clothes washer test procedure is intended to provide a nominal estimate of associated water heating energy that can be used to distinguish among clothes washer models that use different amounts of hot water to provide a consistent basis of comparison applied across all types of clothes washers.
Table 4.1.1 of appendix J2 provides the Temperature Use Factors (TUF), which represent the percentage of wash cycles performed by end-users at each available wash/rinse temperature. For a clothes washer with cold, warm, and hot wash cycles (all with cold rinse), which DOE testing indicates is the most common combination found on commercial clothes washers, the TUFs are assigned as follows: cold wash 37%; warm wash 49%; and hot wash 14%.
NRDC and ASAP commented that the cold temperature usage factor of 37% should be corroborated for the commercial environment. (NRDC and ASAP, No. 11 at p. 2)
DOE does not have consumer usage data indicating the prevalence of cold wash cycles performed on commercial clothes washers. Such data would be required to consider any changes in the test procedure calculations.
DOE reviewed today's proposed rule under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. DOE has concluded that the rule would not have a significant impact on a substantial number of small entities. The factual basis for this certification is as follows:
The Small Business Administration (SBA) considers a business entity to be a small business, if, together with its affiliates, it employs less than a threshold number of workers specified in 13 CFR part 121. These size standards and codes are established by the 2007 North American Industry Classification System (NAICS). The threshold number for NAICS classification code 333312—which applies to commercial laundry, dry cleaning, and pressing machine manufacturers—is 500 employees. Searches of the SBA Web site [7] to identify commercial clothes washer manufacturers within these NAICS codes did not identify any small businesses that manufacture commercial clothes washers. Additionally, DOE checked its own publicly available Compliance Certification Database [8] to identify manufacturers of commercial clothes washers. During its research, DOE did not identify any manufacturer of commercial clothes washers that qualify as small businesses as specified by the SBA employee limits. In addition, the rule proposes only the use of equations for translating modified energy factor and water factor values as measured using DOE's new clothes washer test procedure into their equivalent values as measured using the current test procedure. No change to the test method is proposed.
For these reasons, DOE concludes and certifies that today's proposed rule, if adopted, would not have a significant economic impact on a substantial number of small entities. Accordingly, DOE has not prepared a regulatory flexibility analysis for this rulemaking. DOE will transmit the certification and supporting statement of factual basis to the Chief Counsel for Advocacy of the SBA for review under 5 U.S.C. 605(b).
Manufacturers of commercial clothes washers must certify to DOE that their products comply with any applicable energy conservation standards. In certifying compliance, manufacturers must test their products according to the DOE test procedures for commercial clothes washers, 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 commercial clothes washers. (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.
In this proposed rule, DOE proposes test procedure amendments that it expects will be used to develop and implement future energy conservation standards for commercial clothes washers. 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 proposed rule would amend the existing test procedures without affecting the amount, quality or distribution of energy usage, and, therefore, would not result in any environmental impacts. Thus, this Start Printed Page 8119rulemaking 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.
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. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). 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 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://energy.gov/​gc/​office-general-counsel. DOE examined today's proposed 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.
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 proposed 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 proposed Start Printed Page 8120significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use should the proposal be implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use.
Today's regulatory action to amend the test procedure for measuring the energy efficiency of commercial clothes washers 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.
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, 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. DOE is not requiring the use of any commercial standards in this rulemaking, so these requirements do not apply.
DOE will accept comments, data, and information regarding this proposed rule no later than the date provided in the DATES section at the beginning of this proposed rule. Interested parties may submit comments using any of the methods described in the ADDRESSES section at the beginning of this proposed rule.
It is DOE's policy that all comments may be included in the public docket, without change and as received, including any personal information provided in the comments (except information deemed to be exempt from public disclosure).Start Printed Page 8121
For the reasons stated in the preamble, DOE is proposing to amend parts 429 and 431 of Chapter II of Title 10, Code of Federal Regulations as set forth below:
2. Section 429.46 is amended by revising paragraph (b)(2) to read as follows:
§ 429.46
(i) When testing was conducted using Appendix J1 to subpart B of 10 CFR Part 430 for units manufactured on or after January 8, 2013: The modified energy factor (MEF) in cubic feet per kilowatt hour per cycle (cu ft/kWh/cycle); and the water factor (WF) in gallons per cubic feet per cycle (gal/cu ft/cycle);
(ii) When testing was conducted using Appendix J2 to subpart B of 10 CFR Part 430 for units manufactured on or after January 8, 2013: The modified energy factor (MEF) in cu ft/kWh/cycle, as calculated pursuant to paragraph (b)(2)(ii)(A) of this section after applying the sampling provisions of paragraph (a) of this section; and the water factor (WF) in gal/cu ft/cycle, as calculated pursuant to paragraph (b)(2)(ii)(B) of this section after applying the sampling provisions of paragraph (a) of this section.
(A) Calculate MEF as:
MEF = (MEFJ2 × AMEF) + BMEF
where MEFJ2 is defined as the modified energy factor as calculated in section 4.5 of Appendix J2, and AMEF and BMEF are defined in Table 1:

Front-Loading 1.00 1.00
(iii) When using Appendix J2 to subpart B of 10 CFR Part 430 for units manufactured on or after the effective date of any amended standards for commercial clothes washers based on Appendix J2 efficiency metrics: The modified energy factor (MEF) in cu ft/kWh/cycle, as determined in section 4.5 of Appendix J2; and the integrated water factor (IWF) in gal/cu ft/cycle, as determined in section 4.2.13 of Appendix J2.
4. Section 431.152 is amended by adding in alphabetical order the definitions for “IWF,” “MEF,” “MEF J2,” “WF,” and “WFJ2,” to read as follows:
§ 431.152
Definitions concerning commercial clothes washers.
MEF means modified energy factor, in cubic feet per kilowatt hour per cycle (cu ft/kWh/cycle), as determined in section 4.4 of Appendix J1 to subpart B of 10 CFR Part 430.
MEFJ2 means modified energy factor, in cu ft/kWh/cycle, as determined in section 4.5 of Appendix J2 to subpart B of 10 CFR Part 430.
WF means water factor, in gal/cu ft/cycle, as determined in section 4.2.3 of Appendix J1 to subpart B of 10 CFR Part 430.
WFJ2 means water factor, in gal/cu ft/cycle, as determined in section 4.2.12 of Appendix J2 to subpart B of 10 CFR Part 430.
5. Section 431.154 is revised to read as follows:
§ 431.154
The test procedures for clothes washers in either Appendix J1 or Appendix J2 to subpart B of part 430 of this chapter must be used to test Start Printed Page 8122commercial clothes washers before the effective date of any amended standards based on Appendix J2 efficiency metrics. The test procedures for clothes washers in Appendix J2 to subpart B of part 430 of this chapter must be used to test commercial clothes washers manufactured on or after the effective date of any amended standards based on Appendix J2 efficiency metrics.
1. Docket number EERE-2012-BT-STD-0020. For more information, see DOE's commercial clothes washer rulemaking Web page at http://www1.eere.energy.gov/​buildings/​appliance_​standards/​product.aspx/​productid/​46.
2. The framework document for the energy conservation standards rulemaking for commercial clothes washers is available at DOE's rulemaking Web page: http://www1.eere.energy.gov/​buildings/​appliance_​standards/​rulemaking.aspx/​ruleid/​56. All rulemaking documents, including comments from interested parties, are also available at www.regulations.gov, under Docket #EERE-2012-BT-STD-0020.
3. For top-loading commercial clothes washers, differences between MEF and MEFJ2 for the same model are largely due to differences in the capacity measurement in section 3.1 of both appendices and the equation in section 4.3 of both appendices for calculating per-cycle energy consumption for removal of moisture from the test load (i.e., the “drying energy”). DOE has tested products manufactured both before and after January 8, 2013 and observed that, for a given model, the differences in capacity and drying energy according to appendix J1 and appendix J2 are independent of the unit's efficiency level. Therefore, for each product type, a single linear translation curve can be used that includes models manufactured both before and after the compliance date of the recently amended standards.
4. This correlation is largely due to the revised formula in section 4.3 of appendix J2 for calculating the drying energy. In appendix J1, the drying energy calculation includes a load size adjustment factor of 0.52 for all clothes washer types; whereas, in appendix J2, the drying energy calculation is based on the load usage factors listed in Table 4.1.3 of appendix J2, which differ according to the type of water fill control system available on the clothes washer. The amended drying energy calculation in appendix J2 provides greater consistency with the calculations for determining machine electrical energy and hot water heating energy. For a full description of this amendment, see the residential clothes washer test procedure final rule published in the Federal Register on March 7, 2012. 77 FR 13888, 13914.
5. The term “automatic” water fill used here refers to water fill control systems that determine the water fill level without requiring user intervention or actions. This includes “adaptive” water fill control systems and “fixed” water fill control systems, available on some commercial clothes washers, that provide a fixed water level for all load sizes and no water fill selector or water fill control settings available to the user. Clothes washers with fixed water fill control systems are tested in the same manner as clothes washers with adaptive water fill control systems.
