2. Reporting Currently, for grid-enabled consumer water heater basic models, manufacturers are required to report the uniform energy factor UEF, the rated storage volume in gallons, the first-hour rating in gallons, the recovery efficiency in percent, a declaration that the model is a grid-enabled water heater, whether it is equipped at the point of manufacture with an activation lock, and whether it bears a permanent label applied by the manufacturer that advises purchasers and end-users of the intended and appropriate use of the product. 10 CFR 429.17b2iii.
EPCA, as amended, requires manufacturers to report the quantity of grid-enabled water heaters that the manufacturer ships each year and requires DOE to keep the shipment data reported by manufacturers as confidential business information.13 42
U.S.C. 6295e6Ciiii As stated in section I.B.5 of this document, the August 2015 final rule, which established definitions and energy conservation standards for grid-enabled water heaters, did not establish provisions to require the reporting of shipments by manufacturers. 80 FR
48004, 4800948010 August 11, 2015.
Therefore, DOE is proposing to add reporting requirements to 10 CFR 429.17
that would require manufacturers to report the total number of grid-enabled water heaters shipped each year for sale in the U.S., along with the calendar year that the shipments cover, in accordance with the aforementioned requirement of EPCA. DOE also proposes to clarify that the annual shipments of grid-enabled water heaters reported by manufacturers will be treated as confidential business information by the Department. Because the annual shipments of grid-enabled water heaters would be treated differently than other water heater reporting requirements i.e., the shipments would be reported on an annual basis rather than ongoing based on model availability; and the reported shipments will be treated as confidential business information, DOE
is proposing that the annual shipments be reported separately from the other certification reporting requirements for water heaters in 10 CFR 429.17b.
13 EPCA also requires that utilities and other demand response and thermal storage program operators report annually the quantity of gridenabled water heaters activated for their programs.

3. Reporting Costs and Impacts The addition of reporting requirements for annual shipments of grid-enabled consumer water heaters would newly require manufacturers to report this information. DOE discusses reporting cost impacts corresponding to this proposal in section IV.C of this document. DOE requests comment on its proposal to add new reporting requirements for the number of annual shipments of grid-enabled consumer water heaters, and on its proposal that this information be reported separately from the information that is currently required to be reported under 10 CFR
429.17b.
F. Dishwashers 1. Scope of Applicability This NOPR applies to dishwashers, which are cabinet-like appliances which with the aid of water and detergent, wash, rinse, and dries when a drying process is included dishware, glassware, eating utensils, and most cooking utensils by chemical, mechanical and/or electrical means and discharge to the plumbing drainage system. 10 CFR 430.2.
2. Reporting Under the existing requirements in 10
CFR 429.19b, a certification report must include the following public product-specific information: The estimated annual energy use in kilowatt hours per year kWh/yr and the water consumption in gallons per cycle. 10
CFR 429.19b2. In addition, a certification report must include the following additional product-specific information: The capacity in number of place settings as specified in ANSI/
AHAM DW12010; presence of a soil sensor if yes, the number of cycles required to reach calibration; the water inlet temperature used for testing in degrees Fahrenheit F; the cycle selected for energy testing and whether that cycle is soil-sensing; the options selected for the energy test; and presence of a built-in water softening system if yes, the energy use in kilowatt-hours and the water use in gallons required for each regeneration of the water softening system, the number of regeneration cycles per year, and data and calculations used to derive these values. 10 CFR 429.19b3.
In conducting testing according to DOEs test procedure, section 2.10 of appendix C1 specifies using Cascade with the Grease Fighting Power of Dawn powder as the detergent formulation, at half the quantity specified according to section 4.1 of the industry standard ANSI/Association of

Home Appliance Manufacturers AHAM DW12010 ANSI/AHAM
DW12010. During AHAM task group meetings in 2020 to establish an updated version of the industry standard, in which DOE participated, AHAM informed DOE that Cascade with the Grease Fighting Power of Dawn has been discontinued and has been replaced with Cascade Complete.
AHAM has updated its industry standard to specify the use of Cascade Complete for testing.14 Given that the currently specified detergent is no longer available on the market, DOE
expects that manufacturers may need to or have already had to switch to the new detergent formulation to conduct testing according to appendix C1.
DOE seeks to ensure that any assessment or enforcement testing conducted pursuant to 10 CFR 429.104
and 429.110, respectively, would be performed using the same detergent used by the manufacturer for certifying compliance with the applicable energy conservation standard. Therefore, DOE
is proposing to require manufacturers to indicate in the certification report whether Cascade Complete powder was used as the detergent formulation in lieu of Cascade with the Grease Fighting Power of Dawn. DOE
proposes to add this requirement to the list of additional product-specific information specified at 10 CFR
429.19b3.
DOE also proposes to reorganize the requirements specified at 10 CFR
429.19b3 as a numbered list for easier readability.
3. Reporting Costs and Impacts In this NOPR, DOE proposes to add one additional reported value for dishwashers tested using the new detergent formulation that replaces the currently specified detergent formulation. DOE has tentatively determined that the proposed amendment would not impose additional costs for manufacturers because manufacturers of dishwashers are already submitting certification reports to DOE and should have readily available the information that DOE is proposing to collect as part of this rulemaking i.e., whether a dishwasher model was tested using Cascade Complete powder as the detergent formulation in lieu of Cascade with the Grease Fighting Power of Dawn. DOE
does not believe the revised reporting requirements would cause any measurable change in reporting burden or hours as compared to what 14 See AHAM DW12020 and AHAM DW2
2020, available at www.aham.org.
