Additionally, UOCAVA requires that ‘‘not later than 90 days after the date of each regularly scheduled general election for Federal office, each state and unit of local government which administered the election shall (through the state, in the case of a unit of local government) submit a report to the EAC on the combined number of absentee ballots transmitted to absent uniformed services voters and overseas voters for the election and the combined number of such ballots which were returned by such voters and cast in the election, and shall make such a report available to the general public.’ States that complete and timely submit the UOCAVA section of the survey to the EAC will fulfill their UOCAVA reporting requirement under 52 U.S.C. 20302. In order to fulfill the above requirements, the EAC is seeking information relating to the period from the Federal general election day 2018 +1 through the November 2020 Federal general election. The EAC will provide the data regarding UOCAVA voting to FVAP after data collection is completed. This data sharing reduces burden on local election offices because FVAP does not have to conduct its own data collection to meet its reporting requirements.

ACTION: Notice of petition for waiver and grant of an interim waiver, and request for comments. AGENCY: This document announces receipt of and publishes a petition for waiver from Bradford White Corporation (‘‘BWC’’), which seeks a waiver for a specified consumer water heater basic model from the U.S. Department of Energy (‘‘DOE’’) test procedure used for determining the efficiency of consumer water heaters. BWC asserts that for that identified basic model, application of the calculation specified in the DOE test procedure to determine recovery efficiency yields an ‘‘artificially high’’ value that in turn results in a lower overall uniform energy factor value. Consequently, BWC seeks to use an alternate test procedure to address issues involved in testing the basic model identified in its petition. More specifically, BWC has requested that DOE waive the equation for calculating recovery efficiency of the consumer gasfired storage water heater basic model for which the first occurrence of the main burner cutting out (‘‘cut-out’’) occurs during a draw. Instead, BWC requests that the recovery efficiency for this water heater be calculated using a revised recovery efficiency equation that accounts for the first cut-out occurring during a draw. For the reasons discussed in this document, DOE grants BWC an interim waiver from the DOE’s consumer water heater test procedure for the basic model listed in the interim waiver, subject to use of the alternate test procedure as set forth in the Interim Waiver Order. DOE solicits comments, data, and information concerning BWC’s petition, its suggested alternate test procedure, and the alternate test procedure in the Interim Waiver Order so as to inform its final decision on BWC’s waiver request. DATES: Written comments and information will be accepted on or before November 7, 2019.

Background and Authority The Energy Policy and Conservation Act, as amended (‘‘EPCA’’),1 authorizes the U.S. Department of Energy (‘‘DOE’’) to regulate the energy efficiency of a number of consumer products and certain industrial equipment. (42 U.S.C. 6291–6317) Title III, Part B 2 of EPCA established the Energy Conservation Program for Consumer Products Other Than Automobiles, which sets forth a variety of provisions designed to improve energy efficiency for certain types of consumer products. These products include consumer water heaters, the focus of this document. (42 U.S.C. 6292(a)(4)) The energy conservation program under EPCA consists essentially of four parts: (1) Testing, (2) labeling, (3) Federal energy conservation standards, and (4) certification and enforcement procedures. Relevant provisions of EPCA include definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C. 6294), energy conservation standards (42 U.S.C. 6295), and the authority to require information and reports from manufacturers (42 U.S.C. 6296). The Federal 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 pursuant to EPCA (42 U.S.C. 6295(s)), and (2) making representations about the efficiency of that product (42 U.S.C. 6293(c)). Similarly, DOE must use these test procedures to determine whether the product complies with relevant standards promulgated under EPCA. (42 U.S.C. 6295(s)) Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures DOE is required to follow when prescribing or amending test procedures for covered products. EPCA requires that any test procedures prescribed or amended under this section must be reasonably designed to produce test results which reflect the energy efficiency, energy use, 1 All references to EPCA in this document refer to the statute as amended through America’s Water Infrastructure Act of 2018, Public Law 115–270 (Oct. 23, 2018). 2 For editorial reasons, upon codification in the U.S. Code, Part B was redesignated as Part A. VerDate Sep<11>2014 21:50 Oct 07, 2019 Jkt 250001 or estimated annual operating cost of a covered product during a representative average use cycle or period of use and requires that test procedures not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3)) The test procedure for consumer water heaters is contained in the Code of Federal Regulations (‘‘CFR’’) at 10 CFR part 430, subpart B, appendix E, Uniform Test Method for Measuring the Energy Consumption of Water Heaters. Under 10 CFR 430.27, any interested person may submit a petition for waiver from DOE’s test procedure requirements. DOE will grant a waiver from the test procedure requirements if DOE determines either that the basic model for which the waiver was requested contains a design characteristic that prevents testing of the basic model according to the prescribed test procedures, or that the prescribed test procedures evaluate the basic model in a manner so unrepresentative of its true energy consumption characteristics as to provide materially inaccurate comparative data. 10 CFR 430.27(f)(2). A petitioner must include in its petition any alternate test procedures known to the petitioner to evaluate the basic model in a manner representative of its energy consumption characteristics. 10 CFR 430.27(b)(1)(iii). DOE may grant the waiver subject to conditions, including adherence to alternate test procedures. 10 CFR 430.27(f)(2). As soon as practicable after the granting of any waiver, DOE will publish in the Federal Register a notice of proposed rulemaking to amend its regulations so as to eliminate any need for the continuation of such waiver. 10 CFR 430.27(l). As soon thereafter as practicable, DOE will publish in the Federal Register a final rule to that effect. Id. The waiver process also provides that DOE may grant an interim waiver if it appears likely that the underlying petition for waiver will be granted and/ or if DOE determines that it would be desirable for public policy reasons to grant immediate relief pending a determination on the underlying petition for waiver. 10 CFR 430.27(e)(2). Within one year of issuance of an interim waiver, DOE will either: (i) Publish in the Federal Register a determination on the petition for waiver; or (ii) publish in the Federal Register a new or amended test procedure that addresses the issues presented in the waiver. 10 CFR 430.27(h)(1). When DOE amends the test procedure to address the issues presented in a waiver, the waiver will automatically terminate on the date on which use of PO 00000 Frm 00040 Fmt 4703 Sfmt 4703 53711 that test procedure is required to demonstrate compliance. 10 CFR 430.27(h)(2). II. Bradford White Corporation’s Petition for Waiver and Application for Interim Waiver On July 3, 2019, BWC filed a petition for waiver and a petition for interim waiver from the test procedure for consumer water heaters set forth at 10 CFR part 430, subpart B, appendix E.3 The test procedure for water heaters includes a 24-hour Simulated Use Test (SUT) which consists of a series of hot water draws and standby periods during which the energy consumption of the water heater is measured. For storagetype water heaters, as the stored hot water loses heat through hot water draws and standby losses, the heat source (e.g., the burner, heat pump, electric heating element) will turn on or ‘‘cut-in’’ to heat water within the tank as needed to maintain the setpoint temperature of the thermostat. Once the thermostat is satisfied, the heat source will turn off or ‘‘cut-out.’’ The time during which the heat source is on is referred to as a ‘‘recovery period’’ because the water heater is recovering the heat lost from the stored water. The first recovery period of the 24-hour SUT is used to calculate the ‘‘recovery efficiency’’ of the water heater, which impacts the overall measure of efficiency (i.e., the uniform energy factor (UEF)). BWC stated that for gas and heat pump storage-type consumer water heaters for which the first cut-out of the 24-hour SUT occurs in the middle of one of the draws, the use of average water temperatures in the DOE test procedure calculation for recovery efficiency artificially inflates the calculated energy delivered from the system. BWC asserted that this yields an artificially higher recovery efficiency and results in a lower overall UEF. In support of its waiver request, BWC submitted test data for an individual model based on the platform of the basic model for which BWC seeks a waiver. BWC also requests an interim waiver from the existing DOE test procedure. DOE will grant an interim waiver if it appears likely that the petition for waiver will be granted and/or if DOE determines that it would be desirable for public policy reasons to grant 3 The specific basic model for which the petition applies is the consumer water heater basic model RG2PV50S*N. Although BWC initially included 50 consumer water heater basic models in its July 3, 2019 petition for waiver, BWC later limited the request to include only the RG2PV50S*N basic model via email correspondence on July 30, 2019. This email correspondence is included in the docket at: https://www.regulations.gov/ docket?D=EERE-2019-BT-WAV-0020. E:\FR\FM\08OCN1.SGM 08OCN1 Federal Register / Vol. 84, No. 195 / Tuesday, October 8, 2019 / Notices immediate relief pending a determination of the petition for waiver. See 10 CFR 430.27(e)(2). Based on the assertions made in support of the petition, absent an interim waiver, DOE has initially determined that the DOE test procedure yields unrepresentative results for a consumer water heater that completes the first recovery in the middle of a draw. Specifically, calculating the energy delivered during the first recovery period by using the total mass and average water temperatures across multiple draws to determine the energy delivered yields a higher recovery efficiency for those units for which the first cut-out of the 24-hour SUT occurs during a hot water draw. This in turn would result in a lower overall UEF that is not representative of its true energy efficiency. III. Requested Alternate Test Procedure EPCA requires that manufacturers use DOE test procedures when making representations about the energy consumption and energy consumption costs of covered products. (42 U.S.C. 6293(c)) Consistency is important when making representations about the energy efficiency of products, including when demonstrating compliance with applicable DOE energy conservation standards. Pursuant to its regulations at 10 CFR 430.27, and after consideration of public comments on the petition, DOE may establish in a subsequent Decision and Order an alternate test procedure for the basic model addressed by the interim waiver. BWC seeks to use an alternate test procedure to test and rate one consumer water heater basic model. Specifically, BWC seeks to test the affected consumer water heater basic model according to the DOE test procedure at 10 CFR part 430, subpart B, appendix E, except that the recovery efficiency equation in section 6.3.2 would be replaced with an alternate equation as shown below. Instead of calculating the recovery efficiency using the total mass of hot water drawn and average water temperature rise across all draws that occur until the end of the first recovery period as is done in the DOE test procedure, the requested alternate recovery efficiency equation computes the energy delivered during the first recovery using the mass of hot water drawn and water temperature rise for each draw individually and sums them. As submitted by BWC, the alternative test procedure would replace the equation in section 6.3.2 of Appendix E with the following equation for determining recovery efficiency, hr: Where: Nr = number of draws that the first recovery period occurred during. First Recovery Period: is defined by when the main burner of a storage water heater is lit and raising the temperature of the stored water until cut-out; in the case the cut-out* occurs during a subsequent draw, the first recovery period is to include the time until the draw of water from the tank stops. mi = Mass of draw i. Cpi = Average Specific heat of draw i. *If after the first cut-out occurs during a subsequent draw, a subsequent cut-in occurs prior to the draw completion, the first recovery period is to include the time until the subsequent cut-out occurs, prior to another draw. hour simulated-use test, °F (°C). Qr = Energy consumption of water heater from the beginning of the test to the end of the first recovery period. allow for the accurate measurement of efficiency of the specified basic model, while alleviating the testing problems associated with BWC’s implementation of water heating testing for this basic model. Consequently, DOE has determined that BWC’s petition for waiver will likely be granted. Furthermore, DOE has determined that it is desirable for public policy reasons to grant BWC immediate relief pending a determination of the petition for waiver. For the reasons stated, DOE has granted an interim waiver to BWC for the specified consumer water heater basic model in BWC’s petition. Therefore, DOE has issued an Order stating: (1) BWC must test and rate the following consumer water heater basic model with the alternate test procedure set forth in paragraph (2). jbell on DSK3GLQ082PROD with NOTICES Based on the Federal test procedure DOE understands the remaining variables in the equation submitted by BWC to be as follows: Tdel,i = average water outlet temperature measured during ith draw of the first recovery period, °F (°C). Tin,i = average water inlet temperature measured during the ith draw of the first recovery period, °F (°C).

Grant of an Interim Waiver DOE has reviewed BWC’s application for an interim waiver, the alternate test procedure requested by BWC, and confidential test data submitted by BWC, as well as test data from prior DOE testing of consumer water heaters. For the specified consumer water heater basic model, BWC’s suggested calculation for recovery efficiency, which uses a summation of measurements for each individual draw rather than average values to determine the energy in the delivered hot water during the first recovery period, results in a more accurate calculation of recovery efficiency when the first cutout occurs during a draw, and avoids artificial inflating of the recovery efficiency (resulting in a lower UEF value) that occurs under the calculation in DOE’s current test procedure. BWC’s petition for waiver suggests that this issue may not occur for every individual model within a basic model designation. DOE has modified the suggested alternate test procedure to specify that the alternate calculation applies only if during testing the first cut-out of the 24-hour SUT occurs during a hot water draw.

July 3, 2019 U.S. Department of Energy, Building Technologies Program, MS EE–2J Test Procedure Waivers, 1000 Independence Ave. SW, Washington, DC 20585–0121 Re: Waiver for Test Procedure for Residential Water Heaters To Whom It May Concern: Pursuant to the provisions of 10 CFR 430.27(m), Bradford White Corporation (BWC) is hereby applying for a waiver of the test procedure for calculating the recovery efficiency of residential gas and heat pump storage-type water heaters with a rated storage volume greater than or equal to two gallons, 10 CFR 430, Subpart B, Appendix E, Section 6.3.2. The calculation of the recovery efficiency is used as part of the 24-hour Simulated Use Test (SUT) used to calculate the efficiency, in terms of Uniform Energy Factor (UEF), for residential water heaters. Basic Models for This Waiver Petition The basic models that BWC is respectfully requesting a waiver, including in the interim are listed in E:\FR\FM\08OCN1.SGM 08OCN1 53715 Federal Register / Vol. 84, No. 195 / Tuesday, October 8, 2019 / Notices Attachment 1. This is for both the ‘‘BRADFORD WHITE’’ and ‘‘JETGLAS’’ brand names. Basis for Requested Waiver When the first cut-out during the SUT occurs in the middle of one of the draws, the averaging of these temperatures artificially inflates the calculated energy delivered from the system, which yields an artificially higher calculated recovery efficiency. With an artificially higher recovery efficiency, the resulting UEF is lower. This means that a manufacturer that has a product, as an unintended result of its design, that completes its recovery in the middle of a draw would be disadvantaged versus a competitor that has a similarly designed product but completes its first cut-out between draws, which will result in less units sold. The manner in which a product initiates a recovery and completes its recovery is dependent on a multitude of factors including but not limited to: Storage volume; input; diptube length; diptube design; tank construction/ geometry; thermostat placement; and thermostat differential. It is difficult to ascertain which one or more of these design characteristics would result in the product completing its recovery while a draw is occurring. Regardless, the resulting manner that a product recovers from a water draw should not penalize one product over another. jbell on DSK3GLQ082PROD with NOTICES List of Manufacturers The list of manufacturers of all other basic models of residential gas, oil, and heat pump storage- type water heaters with a rated storage volume greater than or equal to two gallons marketed in the United States known to BWC is included as Attachment 2. Proposed Alternative Test Procedure BWC has reviewed the alternate equation, included as Attachment 3, for calculating recovery efficiency of residential gas, oil, and heat pump storage-type water heaters with a rated storage volume greater than or equal to two gallons with the Air-Conditioning, Heating, & Refrigeration Institute (AHRI), and other interested parties, and believes it provides a more accurate calculation of recovery efficiency. The proposed equation accounts for a recovery that could end in the middle of any draw or in between draws. Furthermore, ASHRAE Standard Project Committee 118.2 has reviewed this equation and included it in the most recent draft of their standard, Method of Testing for Rating Residential Water Heaters. This draft will shortly be VerDate Sep<11>2014 21:50 Oct 07, 2019 Jkt 250001 sent out for public review and comment. We respectfully request DOE grant a waiver to use this alternative equation in lieu of the procedure specified in the current DOE efficiency test procedure. Interim Waiver Request Bradford White Corporation also petitions for an interim waiver to allow us to use the equation shown in Attachment 3 to calculate the recovery efficiency of the identified basic models. We believe it is in both our interest and DOE’s interest to have an interim test procedure, which provides a more accurate calculation of the recovery efficiency of the identified basic models. If BWC is not granted an interim waiver, BWC will continue to be put at a competitive advantage where the resulting UEF will be lower (for the reasons highlighted above) than a similarly designed competitive model, which will result in less units sold.

Energy Conservation Program: Petition for Waiver of Bradford 
White Corporation From the Department of Energy Consumer Water Heaters 
Test Procedure and Grant of Interim Waiver

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

ACTION: Notice of petition for waiver and grant of an interim waiver, 
and request for comments.

-----------------------------------------------------------------------

SUMMARY: This document announces receipt of and publishes a petition 
for waiver from Bradford White Corporation (``BWC''), which seeks a 
waiver for a specified consumer water heater basic model from the U.S. 
Department of Energy (``DOE'') test procedure used for determining the 
efficiency of consumer water heaters. BWC asserts that for that 
identified basic model, application of the calculation specified in the 
DOE test procedure to determine recovery efficiency yields an 
``artificially high'' value that in turn results in a lower overall 
uniform energy factor value. Consequently, BWC seeks to use an 
alternate test procedure to address issues involved in testing the 
basic model identified in its petition. More specifically, BWC has 
requested that DOE waive the equation for calculating recovery 
efficiency of the consumer gas-fired storage water heater basic model 
for which the first occurrence of the main burner cutting out (``cut-
out'') occurs during a draw. Instead, BWC requests that the recovery 
efficiency for this water heater be calculated using a revised recovery 
efficiency equation that accounts for the first cut-out occurring 
during a draw. For the reasons discussed in this document, DOE grants 
BWC an interim waiver from the DOE's consumer water heater test 
procedure for the basic model listed in the interim waiver, subject to 
use of the alternate test procedure as set forth in the Interim Waiver 
Order. DOE solicits comments, data, and information concerning BWC's 
petition, its suggested alternate test procedure, and the alternate 
test procedure in the Interim Waiver Order so as to inform its final 
decision on BWC's waiver request.

SUPPLEMENTARY INFORMATION: 

I. Background and Authority

    The Energy Policy and Conservation Act, as amended (``EPCA''),\1\ 
authorizes the U.S. Department of Energy (``DOE'') to regulate the 
energy efficiency of a number of consumer products and certain 
industrial equipment. (42 U.S.C. 6291-6317) Title III, Part B \2\ of 
EPCA established the Energy Conservation Program for Consumer Products 
Other Than Automobiles, which sets forth a variety of provisions 
designed to improve energy efficiency for certain types of consumer 
products. These products include consumer water heaters, the focus of 
this document. (42 U.S.C. 6292(a)(4))
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through America's Water Infrastructure Act of 2018, 
Public Law 115-270 (Oct. 23, 2018).
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated as Part A.
---------------------------------------------------------------------------

    The energy conservation program under EPCA consists essentially of 
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation 
standards, and (4) certification and enforcement procedures. Relevant 
provisions of EPCA include definitions (42 U.S.C. 6291), test 
procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C. 6294), 
energy conservation standards (42 U.S.C. 6295), and the authority to 
require information and reports from manufacturers (42 U.S.C. 6296).
    The Federal 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 pursuant to EPCA (42 U.S.C. 6295(s)), 
and (2) making representations about the efficiency of that product (42 
U.S.C. 6293(c)). Similarly, DOE must use these test procedures to 
determine whether the product complies with relevant standards 
promulgated under EPCA. (42 U.S.C. 6295(s))
    Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures 
DOE is required to follow when prescribing or amending test procedures 
for covered products. EPCA requires that any test procedures prescribed 
or amended under this section must be reasonably designed to produce 
test results which reflect the energy efficiency, energy use, or 
estimated annual operating cost of a covered product during a 
representative average use cycle or period of use and requires that 
test procedures not be unduly burdensome to conduct. (42 U.S.C. 
6293(b)(3)) The test procedure for consumer water heaters is contained 
in the Code of Federal Regulations (``CFR'') at 10 CFR part 430, 
subpart B, appendix E, Uniform Test Method for Measuring the Energy 
Consumption of Water Heaters.
    Under 10 CFR 430.27, any interested person may submit a petition 
for waiver from DOE's test procedure requirements. DOE will grant a 
waiver from the test procedure requirements if DOE determines either 
that the basic model for which the waiver was requested contains a 
design characteristic that prevents testing of the basic model 
according to the prescribed test procedures, or that the prescribed 
test procedures evaluate the basic model in a manner so 
unrepresentative of its true energy consumption characteristics as to 
provide materially inaccurate comparative data. 10 CFR 430.27(f)(2). A 
petitioner must include in its petition any alternate test procedures 
known to the petitioner to evaluate the basic model in a manner 
representative of its energy consumption characteristics. 10 CFR 
430.27(b)(1)(iii). DOE may grant the waiver subject to conditions, 
including adherence to alternate test procedures. 10 CFR 430.27(f)(2).
    As soon as practicable after the granting of any waiver, DOE will 
publish in the Federal Register a notice of proposed rulemaking to 
amend its regulations so as to eliminate any need for the continuation 
of such waiver. 10 CFR 430.27(l). As soon thereafter as practicable, 
DOE will publish in the Federal Register a final rule to that effect. 
Id.
    The waiver process also provides that DOE may grant an interim 
waiver if it appears likely that the underlying petition for waiver 
will be granted and/or if DOE determines that it would be desirable for 
public policy reasons to grant immediate relief pending a determination 
on the underlying petition for waiver. 10 CFR 430.27(e)(2). Within one 
year of issuance of an interim waiver, DOE will either: (i) Publish in 
the Federal Register a determination on the petition for waiver; or 
(ii) publish in the Federal Register a new or amended test procedure 
that addresses the issues presented in the waiver. 10 CFR 430.27(h)(1).
    When DOE amends the test procedure to address the issues presented 
in a waiver, the waiver will automatically terminate on the date on 
which use of that test procedure is required to demonstrate compliance. 
10 CFR 430.27(h)(2).

II. Bradford White Corporation's Petition for Waiver and Application 
for Interim Waiver

    On July 3, 2019, BWC filed a petition for waiver and a petition for 
interim waiver from the test procedure for consumer water heaters set 
forth at 10 CFR part 430, subpart B, appendix E.\3\ The test procedure 
for water heaters includes a 24-hour Simulated Use Test (SUT) which 
consists of a series of hot water draws and standby periods during 
which the energy consumption of the water heater is measured. For 
storage-type water heaters, as the stored hot water loses heat through 
hot water draws and standby losses, the heat source (e.g., the burner, 
heat pump, electric heating element) will turn on or ``cut-in'' to heat 
water within the tank as needed to maintain the setpoint temperature of 
the thermostat. Once the thermostat is satisfied, the heat source will 
turn off or ``cut-out.'' The time during which the heat source is on is 
referred to as a ``recovery period'' because the water heater is 
recovering the heat lost from the stored water. The first recovery 
period of the 24-hour SUT is used to calculate the ``recovery 
efficiency'' of the water heater, which impacts the overall measure of 
efficiency (i.e., the uniform energy factor (UEF)). BWC stated that for 
gas and heat pump storage-type consumer water heaters for which the 
first cut-out of the 24-hour SUT occurs in the middle of one of the 
draws, the use of average water temperatures in the DOE test procedure 
calculation for recovery efficiency artificially inflates the 
calculated energy delivered from the system. BWC asserted that this 
yields an artificially higher recovery efficiency and results in a 
lower overall UEF. In support of its waiver request, BWC submitted test 
data for an individual model based on the platform of the basic model 
for which BWC seeks a waiver.
---------------------------------------------------------------------------

    \3\ The specific basic model for which the petition applies is 
the consumer water heater basic model RG2PV50S*N. Although BWC 
initially included 50 consumer water heater basic models in its July 
3, 2019 petition for waiver, BWC later limited the request to 
include only the RG2PV50S*N basic model via email correspondence on 
July 30, 2019. This email correspondence is included in the docket 
at: https://www.regulations.gov/docket?D=EERE-2019-BT-WAV-0020.
---------------------------------------------------------------------------

    BWC also requests an interim waiver from the existing DOE test 
procedure. DOE will grant an interim waiver if it appears likely that 
the petition for waiver will be granted and/or if DOE determines that 
it would be desirable for public policy reasons to grant

[[Page 53712]]

immediate relief pending a determination of the petition for waiver. 
See 10 CFR 430.27(e)(2).
    Based on the assertions made in support of the petition, absent an 
interim waiver, DOE has initially determined that the DOE test 
procedure yields unrepresentative results for a consumer water heater 
that completes the first recovery in the middle of a draw. 
Specifically, calculating the energy delivered during the first 
recovery period by using the total mass and average water temperatures 
across multiple draws to determine the energy delivered yields a higher 
recovery efficiency for those units for which the first cut-out of the 
24-hour SUT occurs during a hot water draw. This in turn would result 
in a lower overall UEF that is not representative of its true energy 
efficiency.

III. Requested Alternate Test Procedure

    EPCA requires that manufacturers use DOE test procedures when 
making representations about the energy consumption and energy 
consumption costs of covered products. (42 U.S.C. 6293(c)) Consistency 
is important when making representations about the energy efficiency of 
products, including when demonstrating compliance with applicable DOE 
energy conservation standards. Pursuant to its regulations at 10 CFR 
430.27, and after consideration of public comments on the petition, DOE 
may establish in a subsequent Decision and Order an alternate test 
procedure for the basic model addressed by the interim waiver.
    BWC seeks to use an alternate test procedure to test and rate one 
consumer water heater basic model. Specifically, BWC seeks to test the 
affected consumer water heater basic model according to the DOE test 
procedure at 10 CFR part 430, subpart B, appendix E, except that the 
recovery efficiency equation in section 6.3.2 would be replaced with an 
alternate equation as shown below. Instead of calculating the recovery 
efficiency using the total mass of hot water drawn and average water 
temperature rise across all draws that occur until the end of the first 
recovery period as is done in the DOE test procedure, the requested 
alternate recovery efficiency equation computes the energy delivered 
during the first recovery using the mass of hot water drawn and water 
temperature rise for each draw individually and sums them. As submitted 
by BWC, the alternative test procedure would replace the equation in 
section 6.3.2 of Appendix E with the following equation for determining 
recovery efficiency, [eta]r:
[GRAPHIC] [TIFF OMITTED] TN08OC19.031

Where:

Nr = number of draws that the first recovery period 
occurred during.

    First Recovery Period: is defined by when the main burner of a 
storage water heater is lit and raising the temperature of the 
stored water until cut-out; in the case the cut-out* occurs during a 
subsequent draw, the first recovery period is to include the time 
until the draw of water from the tank stops.

mi = Mass of draw i.
Cpi = Average Specific heat of draw i.

    *If after the first cut-out occurs during a subsequent draw, a 
subsequent cut-in occurs prior to the draw completion, the first 
recovery period is to include the time until the subsequent cut-out 
occurs, prior to another draw.

    Based on the Federal test procedure DOE understands the remaining 
variables in the equation submitted by BWC to be as follows:

Tdel,i = average water outlet temperature measured during 
ith draw of the first recovery period, [deg]F ([deg]C).
Tin,i = average water inlet temperature measured during 
the ith draw of the first recovery period, [deg]F ([deg]C).
Vst = as defined in section 6.3.1.
[rho]2 = density of stored hot water evaluated at 
(Tmax,1 + To)/2, lb/gal (kg/L).
Cp2 = specific heat of stored hot water evaluated at 
(Tmax,1 + To)/2, Btu/(lb[middot][deg]F) (kJ/
(kg[middot][deg]C).
Tmax,1 = maximum mean tank temperature recorded after 
cut-out following the first recovery of the 24-hour simulated use 
test, [deg]F ([deg]C).
To = maximum mean tank temperature recorded prior to the 
first draw of the 24-hour simulated-use test, [deg]F ([deg]C).
Qr = Energy consumption of water heater from the 
beginning of the test to the end of the first recovery period.

IV. Grant of an Interim Waiver

    DOE has reviewed BWC's application for an interim waiver, the 
alternate test procedure requested by BWC, and confidential test data 
submitted by BWC, as well as test data from prior DOE testing of 
consumer water heaters. For the specified consumer water heater basic 
model, BWC's suggested calculation for recovery efficiency, which uses 
a summation of measurements for each individual draw rather than 
average values to determine the energy in the delivered hot water 
during the first recovery period, results in a more accurate 
calculation of recovery efficiency when the first cut-out occurs during 
a draw, and avoids artificial inflating of the recovery efficiency 
(resulting in a lower UEF value) that occurs under the calculation in 
DOE's current test procedure.
    BWC's petition for waiver suggests that this issue may not occur 
for every individual model within a basic model designation. DOE has 
modified the suggested alternate test procedure to specify that the 
alternate calculation applies only if during testing the first cut-out 
of the 24-hour SUT occurs during a hot water draw.
    Based on DOE's review of the alternate test procedure suggested by 
BWC, as modified by DOE, it appears to allow for the accurate 
measurement of efficiency of the specified basic model, while 
alleviating the testing problems associated with BWC's implementation 
of water heating testing for this basic model. Consequently, DOE has 
determined that BWC's petition for waiver will likely be granted. 
Furthermore, DOE has determined that it is desirable for public policy 
reasons to grant BWC immediate relief pending a determination of the 
petition for waiver.
    For the reasons stated, DOE has granted an interim waiver to BWC 
for the specified consumer water heater basic model in BWC's petition. 
Therefore, DOE has issued an Order stating:
    (1) BWC must test and rate the following consumer water heater 
basic model with the alternate test procedure set forth in paragraph 
(2).

------------------------------------------------------------------------
                         Brand                             Basic model
------------------------------------------------------------------------
BRADFORD WHITE, JETGLAS...............................       RG2PV50S*N
------------------------------------------------------------------------

    (2) The alternate test procedure for the BWC basic model referenced 
in paragraph (1) of this Order is the test procedure for consumer water 
heaters prescribed by DOE at 10 CFR part 430, subpart B, appendix E, 
except for equation 6.3.2, as detailed below. All other requirements of 
appendix E and DOE's regulations remain applicable.

[[Page 53713]]

The changes to section 6.3.2 of Appendix E read as follows:

    6.3.2 Recovery Efficiency.
    6.3.2.1 Except as provided in section 6.3.2.2 of this Appendix, 
the recovery efficiency for gas storage-type water heaters, 
[eta]r, is computed as:
[GRAPHIC] [TIFF OMITTED] TN08OC19.032

Where:

M1 = total mass removed from the start of the 24-hour 
simulated-use test to the end of the first recovery period, lb (kg), 
or, if the volume of water is being measured,
M1 = V1[rho]1

Where:

V1 = total volume removed from the start of the 24-hour 
simulated-use test to the end of the first recovery period, gal (L).
[rho]1 = density of the water at the water temperature 
measured at the point where the flow volume is measured, lb/gal (kg/
L).
Cp1 = specific heat of the withdrawn water evaluated at 
(Tdel,1 + Tin,1)/2, Btu/(lb[middot][deg]F) 
(kJ/(kg[middot][deg]C))
Tdel,1 = average water outlet temperature measured during 
the draws from the start of the 24-hour simulated-use test to the 
end of the first recovery period, [deg]F ([deg]C).
Tin,1 = average water inlet temperature measured during 
the draws from the start of the 24-hour simulated-use test to the 
end of the first recovery period, [deg]F ([deg]C).
Vst = as defined in section 6.3.1.
[rho]2 = density of stored hot water evaluated at 
(Tmax,1 + To)/2, lb/gal (kg/L).
Cp2 = specific heat of stored hot water evaluated at 
(Tmax,1 + To)/2, Btu/(lb[middot][deg]F) (kJ/
(kg[middot][deg]C).
Tmax,1 = maximum mean tank temperature recorded after 
cut-out following the first recovery of the 24-hour simulated use 
test, [deg]F ([deg]C).
To = maximum mean tank temperature recorded prior to the 
first draw of the 24-hour simulated-use test, [deg]F ([deg]C).
Qr = the total energy used by the water heater between 
cut-out prior to the first draw and cut-out following the first 
recovery period, including auxiliary energy such as pilot lights, 
pumps, fans, etc., Btu (kJ). (Electrical auxiliary energy shall be 
converted to thermal energy using the following conversion: 1 kWh = 
3412 Btu.)

6.3.2.2 For gas storage-type water heaters, if the first cut-out 
occurs during a draw, the recovery efficiency, [eta]r, is 
computed as:
[GRAPHIC] [TIFF OMITTED] TN08OC19.033

Where:

Nr = number of draws occurring during the first recovery 
period. The first recovery period is defined by the time when the 
main burner of a storage water heater is lit (``cut-in'') and 
continues during the temperature rise of the stored water until the 
main burner cuts-off (``cut-out''); if the cut-out occurs during a 
subsequent draw, the first recovery period includes the time until 
the draw of water from the tank stops. If, after the first cut-out 
occurs but during a subsequent draw, a subsequent cut-in occurs 
prior to the draw completion, the first recovery period includes the 
time until the subsequent cut-out occurs, prior to another draw.
mi = mass of draw i.
Cpi = average specific heat of draw i.
Tdel,i = average water outlet temperature measured during 
ith draw of the first recovery period, [deg]F ([deg]C).
Tin,i = average water inlet temperature measured during 
the ith draw of the first recovery period, [deg]F ([deg]C).
Vst = as defined in section 6.3.1.
[rho]2 = density of stored hot water evaluated at 
(Tmax,1 + To)/2, lb/gal (kg/L).
Cp2 = specific heat of stored hot water evaluated at 
(Tmax,1 + To)/2, Btu/(lb[middot][deg]F) (kJ/
(kg[middot][deg]C).
Tmax,1 = maximum mean tank temperature recorded after 
cut-out following the first recovery of the 24-hour simulated use 
test, [deg]F ([deg]C).
To = maximum mean tank temperature recorded prior to the 
first draw of the 24-hour simulated-use test, [deg]F ([deg]C).
Qr = energy consumption of water heater from the 
beginning of the test to the end of the first recovery period.

    (3) Representations. BWC must make representations about the 
efficiency of the basic model listed in paragraph (1) for compliance, 
marketing, or other purposes only to the extent that the basic model 
has been tested in accordance with the provisions in this alternate 
test procedure and such representations fairly disclose the results of 
such testing.
    (4) This interim waiver shall remain in effect according to the 
provisions of 10 CFR 430.27.
    (5) This interim waiver is issued to BWC on the condition that 
information and test data provided by BWC are valid. DOE may rescind or 
modify this waiver at any time if it determines the factual basis 
underlying the petition for waiver is incorrect, or the results from 
the alternate test procedure are unrepresentative of a basic model's 
true energy consumption characteristics. 10 CFR 430.27(k)(1). Likewise, 
BWC may request that DOE rescind or modify the interim waiver if BWC 
discovers an error in the information provided to DOE as part of its 
petition, determines that the interim waiver is no longer needed, or 
for other appropriate reasons. 10 CFR 430.27(k)(2).
    (6) BWC remains obligated to fulfill any certification requirements 
set forth at 10 CFR part 429.
    DOE makes decisions on waivers and interim waivers for only those 
basic models specifically set out in the petition, not future models 
that may be manufactured by the petitioner. BWC may submit a new or 
amended petition for waiver and application for an interim waiver, as 
appropriate, for additional basic models of consumer water heaters. 
Alternatively, if appropriate, BWC may request that DOE extend the 
scope of a waiver or an interim waiver to include additional basic 
models employing the same technology as the basic model(s) set forth in 
the original petition consistent with 10 CFR 430.27(g).

V. Request for Comments

    DOE is publishing BWC's petition for waiver in its entirety as 
originally submitted, pursuant to 10 CFR 430.27(b)(1)(iv), absent any 
confidential business information.\4\ The petition includes a suggested 
alternate test procedure, as specified in section III of this document, 
to determine the

Re: Waiver for Test Procedure for Residential Water Heaters

    To Whom It May Concern:

    Pursuant to the provisions of 10 CFR 430.27(m), Bradford White 
Corporation (BWC) is hereby applying for a waiver of the test procedure 
for calculating the recovery efficiency of residential gas and heat 
pump storage-type water heaters with a rated storage volume greater 
than or equal to two gallons, 10 CFR 430, Subpart B, Appendix E, 
Section 6.3.2. The calculation of the recovery efficiency is used as 
part of the 24-hour Simulated Use Test (SUT) used to calculate the 
efficiency, in terms of Uniform Energy Factor (UEF), for residential 
water heaters.

Basic Models for This Waiver Petition

    The basic models that BWC is respectfully requesting a waiver, 
including in the interim are listed in

[[Page 53715]]

Attachment 1. This is for both the ``BRADFORD WHITE'' and ``JETGLAS'' 
brand names.

Basis for Requested Waiver

    When the first cut-out during the SUT occurs in the middle of one 
of the draws, the averaging of these temperatures artificially inflates 
the calculated energy delivered from the system, which yields an 
artificially higher calculated recovery efficiency. With an 
artificially higher recovery efficiency, the resulting UEF is lower. 
This means that a manufacturer that has a product, as an unintended 
result of its design, that completes its recovery in the middle of a 
draw would be disadvantaged versus a competitor that has a similarly 
designed product but completes its first cut-out between draws, which 
will result in less units sold.
    The manner in which a product initiates a recovery and completes 
its recovery is dependent on a multitude of factors including but not 
limited to: Storage volume; input; diptube length; diptube design; tank 
construction/geometry; thermostat placement; and thermostat 
differential. It is difficult to ascertain which one or more of these 
design characteristics would result in the product completing its 
recovery while a draw is occurring. Regardless, the resulting manner 
that a product recovers from a water draw should not penalize one 
product over another.

List of Manufacturers

    The list of manufacturers of all other basic models of residential 
gas, oil, and heat pump storage- type water heaters with a rated 
storage volume greater than or equal to two gallons marketed in the 
United States known to BWC is included as Attachment 2.

Proposed Alternative Test Procedure

    BWC has reviewed the alternate equation, included as Attachment 3, 
for calculating recovery efficiency of residential gas, oil, and heat 
pump storage-type water heaters with a rated storage volume greater 
than or equal to two gallons with the Air-Conditioning, Heating, & 
Refrigeration Institute (AHRI), and other interested parties, and 
believes it provides a more accurate calculation of recovery 
efficiency. The proposed equation accounts for a recovery that could 
end in the middle of any draw or in between draws.
    Furthermore, ASHRAE Standard Project Committee 118.2 has reviewed 
this equation and included it in the most recent draft of their 
standard, Method of Testing for Rating Residential Water Heaters. This 
draft will shortly be sent out for public review and comment. We 
respectfully request DOE grant a waiver to use this alternative 
equation in lieu of the procedure specified in the current DOE 
efficiency test procedure.

Interim Waiver Request

    Bradford White Corporation also petitions for an interim waiver to 
allow us to use the equation shown in Attachment 3 to calculate the 
recovery efficiency of the identified basic models. We believe it is in 
both our interest and DOE's interest to have an interim test procedure, 
which provides a more accurate calculation of the recovery efficiency 
of the identified basic models.
    If BWC is not granted an interim waiver, BWC will continue to be 
put at a competitive advantage where the resulting UEF will be lower 
(for the reasons highlighted above) than a similarly designed 
competitive model, which will result in less units sold.

Respectfully submitted,

Bradford White Corporation
