I. Introduction

    DOE established an early assessment review process to conduct a 
more focused analysis of a specific set of facts or circumstances that 
would allow DOE to determine that, based on statutory criteria, an 
amended test procedure is not warranted. The purpose of this review is 
to limit the resources, from both DOE and stakeholders, committed to 
rulemakings that will not satisfy the requirements in EPCA that an 
amended test procedure more accurately or fully comply with the 
requirement that the test procedure produces results that measure 
energy use during a representative average use cycle for equipment, and 
not be unduly burdensome to conduct. See 85 FR 8626, 8653-8654 (Feb. 
14, 2020).
    As part of the early assessment, DOE publishes an RFI in the 
Federal Register, announcing that DOE is initiating a rulemaking 
proceeding and soliciting comments, data, and information on whether an 
amended test procedure would more accurately measure energy use during 
a representative average use cycle or reduce testing burden. Based on 
the information received in response to the RFI and DOE's own analysis, 
DOE will determine whether to proceed with a rulemaking for an amended 
test procedure.
    If DOE makes an initial determination based upon available evidence 
that an amended test procedure would not meet the applicable statutory 
criteria, DOE would engage in notice and comment rulemaking before 
issuing a final determination that an amended test procedure is not 
warranted. If DOE reaches such a determination, the rulemaking would be 
concluded, which would satisfy the Department's 7-year-lookback test 
procedure review requirement under the statute (as discussed in section 
I.A of this document).
    Conversely, if DOE makes an initial determination that an amended 
test procedure would satisfy the applicable statutory criteria, 
including that adoption of a consensus-based test procedure as the DOE 
test procedure would more accurately or fully comply with statutory 
requirements, or DOE's analysis is inconclusive, DOE would undertake 
the preliminary stages of a rulemaking to issue an amended test 
procedure. Beginning such a rulemaking, however, would not preclude DOE 
from later making a determination that an amended test procedure would 
not satisfy the requirements in EPCA, based upon the full suite of 
DOE's analyses. Id. at 85 FR 8654.

A. Authority

    The Energy Policy and Conservation Act, as amended (``EPCA''),\1\ 
among other things, authorizes 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 C \2\ of EPCA, added by Public Law 
95-619, Title IV, Sec.  441(a) (42 U.S.C. 6311-6317 as codified), 
established the Energy Conservation Program for Certain Industrial 
Equipment, which sets forth a variety of provisions designed to improve 
energy efficiency. This equipment includes commercial and industrial 
pumps (``pumps''), the subject of this RFI. (42 U.S.C. 6311(1)(A))
---------------------------------------------------------------------------

    \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 (October 23, 2018).
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part C was redesignated Part A-1.
---------------------------------------------------------------------------

    Under EPCA, DOE's energy conservation program 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. 
6311), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 
6315), energy conservation standards (42 U.S.C. 6313), and the 
authority to require information and reports from manufacturers (42 
U.S.C. 6316; 42 U.S.C. 6296).
    Federal energy efficiency requirements for covered equipment 
established under EPCA generally supersede State laws and regulations 
concerning energy conservation testing, labeling, and standards. (42 
U.S.C. 6316(a) and (b); 42 U.S.C. 6297) DOE may, however, grant waivers 
of Federal preemption for particular State laws or regulations, in 
accordance with the procedures and other provisions of EPCA. (42 U.S.C. 
6316(a); 42 U.S.C. 6297(d))
    EPCA also requires that, at least once every 7 years, DOE evaluate 
test procedures for each type of covered equipment, including pumps, to 
determine whether amended test procedures would more accurately or 
fully comply with the requirements for the test procedures to not be 
unduly burdensome to conduct and be reasonably designed to produce test 
results that reflect energy efficiency, energy use, and estimated 
operating costs during a representative average use cycle. (42 U.S.C. 
6314(a)(1)) DOE is publishing this RFI to collect data and information 
to inform its decision, in

[[Page 60736]]

order to satisfy the 7-year review requirement.

B. Rulemaking History

    DOE's test procedure for measuring pump energy efficiency was 
established in a final rule published on January 25, 2016. 81 FR 4086 
(``January 2016 Final Rule'').\3\ The January 2016 Final Rule 
established definitions for the term pump, certain pump components, and 
several categories and configurations of pumps. The procedure 
incorporates by reference the Hydraulic Institute (``HI'') Standard 
40.6-2014, ``Methods for Rotodynamic Pump Efficiency Testing'' (``HI 
40.6-2014''), with several modifications related to measuring the 
hydraulic power, shaft power, and electric input power of pumps, 
inclusive of electric motors and any continuous or non-continuous 
controls.\4\
---------------------------------------------------------------------------

    \3\ On March 23, 2016, DOE published a correction to the January 
2016 Final Rule to correct the placement of the product-specific 
enforcement provisions related to pumps under 10 CFR 429.134(h). 81 
FR 15426.
    \4\ A ``continuous control'' is a control that adjusts the speed 
of the pump driver continuously over the driver operating speed 
range in response to incremental changes in the required pump flow, 
head, or power output. A ``non-continuous control'' is a control 
that adjusts the speed of a driver to one of a discrete number of 
non-continuous preset operating speeds, and does not respond to 
incremental reductions in the required pump flow, head, or power 
output. 10 CFR 431.462.
---------------------------------------------------------------------------

II. Request for Information

    DOE is publishing this RFI to collect data and information during 
the early assessment review to inform its decision, consistent with its 
obligations under EPCA, as to whether the Department should proceed 
with a test procedure rulemaking. Accordingly, in the following 
sections, DOE has identified specific issues on which it seeks input to 
aid its analysis of whether an amended test procedure for pumps would 
more accurately or fully comply with the requirement that the test 
procedure produce results that measure energy use during a 
representative average use cycle for the equipment, and not be unduly 
burdensome to conduct. In particular, DOE is interested in: (1) Any 
information indicating that there has not been sufficient technological 
or other changes since DOE last conducted a test procedure rulemaking 
analysis for pumps to suggest an amended test procedure could satisfy 
these criteria; or (2) whether adopting a consensus-based test 
procedure, without modification, as the DOE test procedure would more 
accurately or fully comply with the statutory requirement. DOE also 
welcomes comments on other issues relevant to its early assessment that 
may not specifically be identified in this document.

A. Energy Use Measurements

    DOE's current test procedure for pumps can be found at 10 CFR part 
431, subpart Y, appendix A, ``Uniform Test Method for the Measurement 
of Energy Consumption of Pumps'' (``Appendix A''). It measures energy 
use by determining the constant load pump energy index 
(``PEICL'')--used for pumps sold without continuous or non-
continuous controls--and the variable load pump energy index 
(``PEIVL'')--used for pumps sold with continuous or non-
continuous controls. 10 CFR 431.464(a)(2). The PEICL and 
PEIVL metrics both describe the weighted average performance 
of the rated pump at specific load points (i.e., pump energy rating, or 
``PER''), normalized with respect to the performance of a minimally 
compliant pump without controls (``PERSTD''). The PER 
represents an average of driver power input to the motor at three load 
points (for pumps sold without continuous or non-continuous controls) 
or an average of driver power input to the continuous or non-continuous 
controls at four load points (for pumps sold with such controls).
    The test procedure contains methods to determine the appropriate 
index for all equipment to which this test procedure applies either by 
(a) measuring the bare pump shaft input power and calculating 
efficiency, or losses, of the motor and any continuous control (i.e., 
calculation-based method) or (b) measuring the input power to the 
driver, or motor, and any continuous or non-continuous controls for a 
given pump directly (i.e., testing-based method). See 10 CFR part 431, 
subpart Y, appendix A, Table 1. The test procedure also prescribes the 
specific categories and configurations of pumps to which the 
calculation-based and testing-based methods apply. Id. DOE seeks 
comment on whether existing test procedure requirements (e.g., 
measurement equipment, test conditions, data collection, specific 
testing-based and calculation-based approaches) accurately measure 
energy use without adding undue burden to the test procedure. DOE is 
particularly interested in whether changes in equipment testing 
methodology or new equipment on the market since the test procedure was 
established may necessitate amending the procedure.

B. Representative Average Use Cycle

    The current DOE test procedure for pumps measures energy use during 
a representative average use cycle. Pumps are used in a variety of 
situations where there is a need to move liquids from one location to 
another. As currently defined, a pump is a type of equipment designed 
to move liquids (including entrained gases, free solids, and totally 
dissolved solids) by physical or mechanical action. It includes both 
the bare pump itself and the mechanical equipment, driver, and controls 
that a manufacturer includes with the bare pump at the time of sale. 
See 10 CFR 431.462. DOE seeks comment on what constitutes a 
representative average use cycle for pumps.

C. Test Burden Reductions

    In the January 2016 Final Rule, DOE estimated a cost of $2.9 
million to the industry to test pump basic models in accordance with 
the test procedure adopted in the Final Rule. 81 FR 4368 (January 26, 
2016).\5\ This estimate included setup, testing, and takedown, with the 
final industry cost calculation assuming two tests per basic model. 
DOE's test procedure for pumps allows manufacturers the option of 
rating pumps sold with single-phase motors as bare pumps (using a 
calculation-based method) or as pumps with motors using the testing-
based methods.\6\ DOE's calculations of testing costs assumed that the 
majority of pump basic models would be certified based on the bare pump 
configuration and subsequent ratings for the same bare pump sold with 
any number of applicable motors and continuous controls could be 
generated using the calculation-based approach. DOE seeks comment on 
whether any modifications to the test procedure could reduce these 
costs while still allowing for accurate determinations of energy use 
during a representative average use cycle.
---------------------------------------------------------------------------

    \5\ See Final Rule ``Technical Support Document: Energy 
Efficiency Program for Consumer Products and Commercial and 
Industrial Equipment: Pumps'', Section 12.4.9, ``Compliance, 
Certification and Enforcement Testing Expense'', December 2015. 
EERE-2011-BT-STD-0031.
    \6\ In the case of the calculation-based method, only the bare 
pump performance is physically measured--the performance of the 
motor and any continuous or non-continuous controls would be 
addressed through a series of calculations. In the case of the 
testing-based method, the input power to the pump at the motor or at 
the continuous or non-continuous control, if any, is directly 
measured and used to calculate PEICL or PEIVL. 
81 FR 4127-4131 (January 25, 2016).
---------------------------------------------------------------------------

D. Consensus-Based Test Procedures

    The current DOE test procedure for pumps generally incorporates by 
reference HI 40.6-2014, with minor modifications to ensure repeatable 
and reproducible test results and additional provisions related to 
measuring the hydraulic power, shaft power, and

[[Page 60737]]

electric input power of pumps, inclusive of electric motors and any 
continuous or non-continuous controls, which are not included in HI 
40.6-2014. DOE seeks comment on the availability of consensus-based 
test procedures for measuring the energy use of pumps that could be 
adopted without modification and more accurately or fully comply with 
the requirement that the test procedure produce results that measure 
energy use during a representative average use cycle for the equipment, 
and not be unduly burdensome to conduct. With respect to consensus-
based test procedures, DOE describes recent developments in this area 
since the publication of the January 2016 Final Rule below.
a. HI Standard 40.6
    As stated, DOE's test procedure for pumps generally incorporates HI 
40.6-2014. Since publication of the January 2016 Final Rule, the 
Hydraulics Institute updated HI 40.6-2014 with the publication of HI 
Standard 40.6-2016, ``Methods for Rotodynamic Pump Efficiency Testing'' 
(``HI 40.6-2016''). This update aligned the definitions and procedures 
specified in HI Standard 40.6 with the DOE test procedure for pumps.
    DOE requests comments on the updated standard HI 40.6-2016 and on 
whether DOE should incorporate HI 40.6-2016 by reference as the DOE 
test procedure for pumps. Specifically, DOE requests information on 
whether the updates in HI 40.6-2016 impact the measured values, and if 
so, to what extent. DOE also requests information on the impact of the 
updates in HI 40.6-2016 to the test burden and the representativeness 
of the test results.
b. IEC 61800-9-2:2017 (Adjustable Speed Electrical Power Drive Systems)
    While DOE's test procedure for pumps incorporates by reference HI 
40.6-2014, as noted previously, DOE also includes additional provisions 
related to measuring the hydraulic power, shaft power, and electric 
input power of pumps, inclusive of electric motors and any continuous 
or non-continuous controls--these provisions are not included in HI 
40.6-2014, and at the time of finalization of DOE's test procedure, 
similar provisions were not available in any other industry test 
standard. Since publication of the January 2016 Final Rule, the 
International Electrotechnical Commission (``IEC'') published standard 
IEC 61800-9-2:2017 ``Adjustable speed electrical power drive systems--
Part 9-2: Ecodesign for power drive systems, motor starters, power 
electronics and their driven applications--Energy efficiency indicators 
for power drive systems and motor starters'' (``IEC 61800-9-2:2017''), 
which addresses test methods and reference losses for motor and 
controls combinations (i.e., ``power drive systems''). Specifically, 
Annex A of IEC 61800-9-2:2017 describes reference losses for complete 
drive modules (i.e., controls) and power drive systems at different 
operating points, comparable to the approach already presented in 
section VII.E.1.2 of appendix A to subpart Y of part 431. A second 
edition of this standard is projected to be published in November 2021 
to address further the test method and evaluate the reference losses 
based on test results.\7\
---------------------------------------------------------------------------

    \7\ Electric Motors Systems Annex (EMSA). (March 2019) Round 
Robin of Converter Losses, Report of Results of Phase 1. Available 
at: https://www.motorsystems.org/files/otherfiles/0000/0206/RR_C_report_phase_1_final_1_d_20190322.pdf.
---------------------------------------------------------------------------

    DOE requests comments on the approach presented in Annex A of IEC 
61800-9-2:2017 to represent reference losses for complete drive modules 
(i.e., controls) and power drive systems (i.e., motor and controls 
combinations) and on whether DOE should incorporate by reference this 
approach in lieu of the calculations in section VII of Appendix A, or 
if any considerations for updates should be postponed until the second 
edition of IEC 61800-9-2 is published.
c. Adoption of Other Consensus-Based Test Procedures
    DOE requests comment on whether another consensus-based test 
procedure could be adopted, with or without modification, and meet the 
criteria in EPCA related to representativeness and test burden. If so, 
DOE requests comment on the benefits and burdens of adopting any such 
industry/voluntary consensus-based or other appropriate test procedure, 
with or without modification.

III. Submission of Comments

    DOE invites all interested parties to submit in writing by December 
14, 2020, comments and information on matters addressed in this notice 
and on other matters relevant to DOE's early assessment of whether 
amendments to the test procedure for pumps would more accurately or 
fully comply with the requirement that the test procedure produces 
results that measure energy use during a representative average use 
cycle for the equipment, and not be unduly burdensome to conduct.
