Energy Conservation Program: 

Decision and Order Granting a Waiver 

to Vinotemp International Corp. From 

the Department of Energy Walk-In 

Coolers and Walk-In Freezers Test 

Procedure 

AGENCY: Office of Energy Efficiency and 

Renewable Energy, Department of 

Energy. 

ACTION: Notification of decision and 

order. 

SUMMARY: The U.S. Department of 

Energy (‘‘DOE’’) gives notification of a 

Decision and Order (Case Number 

2020–005) that grants to Vinotemp 

International Corp. (‘‘Vinotemp’’) a 

waiver from specified portions of the 

DOE test procedure for determining the 

energy efficiency of specified walk-in 

cooler refrigeration systems. Due to the 

design of the specific basic models of 

walk-in refrigeration systems subject to 

this Decision and Order, the current test 

procedure evaluates such models in a 

manner that is unrepresentative of their 

energy use. Under the Decision and 

Order, Vinotemp is required to test and 

rate the specified basic models of its 

walk-in cooler refrigeration systems in 

accordance with the alternate test 

procedure set forth in the Decision and 

Order. 

DATES: The Decision and Order is 

effective on July 13, 2021. The Decision 

and Order will terminate upon the 

compliance date of any future 

amendment to the test procedure for 

walk-in coolers and walk-in freezers 

located at title 10 of the Code of Federal 

Regulations (‘‘CFR’’), part 431, subpart 

R, appendix C that addresses the issues 

presented in this waiver. At such time, 

Vinotemp must use the relevant test 

procedure for this equipment for any 

testing to demonstrate compliance with 

the applicable standards, and any other 

representations of energy use.

SUPPLEMENTARY INFORMATION: In 

accordance with § 431.401(f)(2) of title 

10 of the Code of Federal Regulations 

(‘‘CFR’’) (10 CFR 431.401(f)(2)), DOE 

gives notification of the issuance of its 

Decision and Order as set forth below. 

The Decision and Order grants 

Vinotemp a waiver from the applicable 

test procedure at 10 CFR part 431, 

subpart R, appendix C for specified 

basic models of walk-in cooler 

refrigeration systems, and provides that 

Vinotemp must test and rate such walkin cooler refrigeration systems using the 

alternate test procedure specified in the 

Decision and Order. Vinotemp’s 

representations concerning the energy 

efficiency of the specified basic models 

must be based on testing according to 

the provisions and restrictions in the 

alternate test procedure set forth in the 

Decision and Order, and the 

representations must fairly disclose the 

test results. Distributors, retailers, and 

private labelers are held to the same 

requirements when making 

representations regarding the energy 

efficiency of these products. (42 U.S.C. 

6314(d)) 

Manufacturers not currently 

distributing equipment in commerce in 

the United States that employ a 

technology or characteristic that results 

in the same need for a waiver from the 

applicable test procedure must petition 

for and be granted a waiver prior to the 

distribution in commerce of that 

equipment in the United States. 

Manufacturers may also submit a 

request for interim waiver pursuant to 

the requirements of 10 CFR 431.401. (10 

CFR 431.401(j)) 

Case # 2020–005 

Decision and Order 

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 C 2 of EPCA 

established the Energy Conservation 

Program for Certain Industrial 

Equipment, which sets forth a variety of 

provisions designed to improve the 

energy efficiency for certain types of 

industrial equipment. This equipment 

includes walk-in coolers and walk-in 

freezers (collectively, ‘‘walk-ins’’), the 

focus of this document. (42 U.S.C. 

6311(1)(G)) 

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. 

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. 6299). 

The Federal testing requirements 

consist of test procedures that 

manufacturers of covered equipment 

must use as the basis for: (1) Certifying 

to DOE that their equipment complies 

with the applicable energy conservation 

standards adopted pursuant to EPCA (42 

U.S.C. 6316(a); 42 U.S.C. 6295(s)), and 

(2) making representations about the 

efficiency of that equipment (42 U.S.C. 

6314(d)). Similarly, DOE must use these 

test procedures to determine whether 

the equipment complies with relevant 

standards promulgated under EPCA. (42 

U.S.C. 6316(a); 42 U.S.C. 6295(s)) 

Under 42 U.S.C. 6314, EPCA sets forth 

the criteria and procedures DOE is 

required to follow when prescribing or 

amending test procedures for covered 

walk-ins. EPCA requires that any test 

procedures prescribed or amended 

under this section must be reasonably 

designed to produce test results which 

reflect energy efficiency, energy use or 

estimated annual operating cost of walkins during a representative average use 

cycle and requires that test procedures 

not be unduly burdensome to conduct. 

(42 U.S.C.6314(a)(2)) The test procedure 

for walk-ins is set forth in the Code of 

Federal Regulations (‘‘CFR’’) at 10 CFR 

part 431, subpart R, appendix C, 

Uniform Test Method for the 

Measurement of Net Capacity and 

AWEF of Walk-in Cooler and Walk-in 

Freezer Refrigeration Systems 

(‘‘Appendix C’’). 

Any interested person may submit a 

petition for waiver from DOE’s test 

procedure requirements. 10 CFR 

431.401(a)(1). 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

4The waiver process under 10 CFR 431.401 

requires that a petition for interim waiver must

431.401(b)(2)) 

5The December 10, 2020 update was consistent 

with a letter from the Air-Conditioning, Heating, 

and Refrigeration Institute (‘‘AHRI’’) recommending 

that a 45 °F minimum temperature be used for 

testing wine cellar cooling systems, and that testing 

be conducted at an external static pressure (‘‘ESP’’) 

value equal to 50 percent of the maximum ESP to 

be specified by manufacturers for each basic model.

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 431.401(f)(2). 

DOE may grant the waiver subject to 

conditions, including adherence to 

alternate test procedures. Id. 

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 431.401(l). As soon thereafter as 

practicable, DOE will publish in the 

Federal Register a final rule to that 

effect. Id. 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 431.401(h)(3). 

II. Vinotemp’s Petition for Waiver: 

Assertions and Determinations 

DOE received correspondence from 

Vinotemp, docketed on June 29, 2020, 

seeking an interim waiver from the DOE 

test procedure applicable to walk-ins set 

forth in Appendix C for certain basic 

models Vinotemp characterized as 

‘‘wine cellar’’ systems. (Vinotemp, No. 

1 3) By letter docketed on December 10, 

2020, Vinotemp submitted a petition for 

waiver for certain basic models of walkin cooler refrigeration systems to 

supplement its original interim waiver 

request (Vinotemp, No. 3).4 The 

December 10, 2020 submission also 

explicitly stated that none of the basic 

models could operate below 45 °F and 

provided external static pressure 

(‘‘ESP’’) values for the subject basic 

models.5 Vinotemp included additional 

basic models and clarified the specified 

external static pressure values as 

maximum values (rather than tested 

values) for the specified basic models in 

an updated petition for interim waiver, 

received on March 11, 2021 (Vinotemp, 

No. 10). Vinotemp stated that the 

specified basic models of walk-in cooler 

refrigeration systems operate at a 

temperature range of 45 °F to 65 °F and 

50 to 70 percent relative humidity 

(‘‘RH’’), rather than the 35 °F with less 

than 50 percent RH test conditions 

prescribed by the test procedure for 

walk-in cooler applications. Vinotemp 

stated that the units operate at 

temperature and relative humidity 

ranges optimized for long-term storage 

of wine, reflecting conditions in natural 

caves, and that they are usually located 

in air-conditioned spaces. Vinotemp 

asserted that the specified units cannot 

operate at 35 °F. 

On May 4, 2021, DOE published a 

notification announcing its receipt of 

the petition for waiver and granted 

Vinotemp an interim waiver. 86 FR 

23692 (‘‘Notification of Petition for 

Waiver’’). In the Notification of Petition 

for Waiver, DOE noted that the ‘‘Selfcontained’’ and ‘‘Self-packaged’’ basic 

models of walk-in refrigeration systems 

identified by Vinotemp in its petition 

are self-contained, single-package 

systems. Although not specifically 

addressed in Vinotemp’s request for 

waiver, DOE notes that operating a wine 

cellar at the 35 °F condition would 

adversely mechanically alter the 

intended performance of the system, 

which would include icing of the 

evaporator coil that could potentially 

damage the compressor, and would not 

result in an accurate representation of 

the performance of the cooling unit. 86 

FR 23692, 23695. Additionally, 

although not explicitly identified by 

Vinotemp, DOE recognized that because 

of their single-package design, these 

basic models have insufficient space 

within the units and insufficient lengths 

of liquid line and evaporator outlet line 

for the dual mass flow meters (i.e., two 

independent meters) and the dual 

temperature and pressure measurements 

(i.e., two independent sets of measuring 

equipment) required by the test 

procedure’s refrigerant enthalpy 

method. Id. AHRI 1250–2009 

(‘‘Standard for Performance Rating of 

Walk-in Coolers and Freezers’’ 6)—the 

industry testing standard on which 

DOE’s test procedure is based—does not 

include specific provisions for testing 

single-package systems, and testing 

these basic models using the refrigerant 

enthalpy method as required by 

Appendix C would require extensive 

additional piping to route the pipes out 

of the system—where the components 

could be installed—and then back in. 

This additional piping would impact 

unit performance, would likely be 

inconsistent between test labs, and 

would result in unrepresentative test 

values for the unit under test. AHRI has 

published a revised version of the test 

standard that provides provisions for 

single-package systems without 

requiring extensive additional piping 

(AHRI 1250–2020, 2020 Standard for 

Performance Rating of Walk-in Coolers 

and Freezers). 

In the Notification of Petition for 

Waiver, DOE established an alternate 

test procedure that was a modified 

version of the alternate test procedure 

suggested by Vinotemp. 86 FR 23692, 

23698–23700. The alternate test 

procedure prescribed in the Notification 

of Petition for Waiver is the same as the 

alternate test procedure established in 

other waivers and interim waivers 

granted by DOE for similarly situated 

equipment.7 Specifically, the required 

alternate test procedure establishes unit 

cooler air inlet conditions of 55 °F and 

55 percent RH, specifies primary and 

secondary capacity measurement 

methods for single-package systems, 

requires testing at 50 percent of 

maximum external static pressure for 

ducted units, and defines wine cellar 

box load and evaporator cycle periods 

for calculation of Annual Walk-in 

Energy Factor (‘‘AWEF’’) for the 

specified basic models of walk-in cooler 

refrigeration systems. Id. DOE solicited 

comments from interested parties on all 

aspects of the petition and the modified 

alternate test procedure. Id. 

DOE received one comment, which 

was submitted by the Pacific Gas and 

Electric Company, San Diego Gas and 

Electric, and Southern California Edison 

(collectively, ‘‘the CA IOUs’’).8 The CA 

IOUs stated their agreement with DOE 

that since the subject basic models are 

unable to operate below 45 °F, there is 

limited opportunity for market 

confusion from labeling the products 

tested according to the test procedure 

waivers as walk-in coolers. (CA IOUs, 

No. 12) 

For the reasons explained here and in 

the Notification of Petition for Waiver, 

absent a waiver the basic models 

identified by Vinotemp in its petition 


jbell on DSKJLSW7X2PROD with NOTICES
36734 Federal Register / Vol. 86, No. 131 / Tuesday, July 13, 2021 / Notices 

cannot be tested and rated for energy 

consumption on a basis representative 

of their true energy consumption 

characteristics. As noted previously, the 

alternate test procedure prescribed in 

the Interim Waiver modified Vinotemp’s 

suggested alternate test procedure by 

including ESP provisions for certain 

systems that can be installed with (1) 

ducted evaporator air, (2) with or 

without ducted evaporator air, (3) 

ducted condenser air, or (4) with or 

without ducted condenser air. For such 

systems, testing is conducted at 50 

percent of the maximum ESP specified 

by the manufacturer, subject to a 

tolerance of ¥0.00/+0.05 inches of 

water column (‘‘in. wc.’’). (Vinotemp, 

No. 2) 

Selection of a representative ESP 

equal to half the maximum ESP is based 

on the expectation that most 

installations will require less than the 

maximum allowable duct length. In the 

absence of field data, DOE expects that 

a range of duct lengths from the 

minimal length to the maximum 

allowable length would be used; thus, 

half of the maximum ESP would be 

representative of most installations. 

If the basic model provides multiple 

condenser or unit cooler fan speed 

settings, the speed setting used is as 

instructed in the unit’s installation 

instructions. However, if the installation 

instructions do not specify a fan speed 

setting for ducted installation, systems 

that can be installed with ducts would 

be tested with the highest available fan 

speed. The ESP is set for testing either 

by symmetrically restricting the outlet 

duct or, if using the indoor air enthalpy 

method, by adjusting the airflow 

measurement apparatus blower. 

The alternate test procedure also 

specifies the requirements for measuring 

ESP consistent with the provisions 

provided in AHRI 1250–2020 when 

using the indoor air enthalpy method 

with unit coolers. 

Additionally, the alternate test 

procedure requires that specified basic 

models that are split systems must be 

tested as matched pairs. According to 

Vinotemp’s petition, the walk-in 

refrigeration system basic models that 

are split-systems are sold as full systems 

(i.e., matched pairs) rather than as 

individual unit cooler and condensing 

unit components. This Order provides 

no direction regarding refrigerant line 

connection operating conditions, and as 

such is inapplicable to testing the basic 

models as individual components. 

Consequently, this Order addresses only 

matched-pair testing of the specified 

basic models that are split-systems. 

Contrary to Vinotemp’s request, the 

Order does not modify the condenser air 

entering dry bulb temperature for 

outdoor condensers. 86 FR 23692, 

23697. Vinotemp had suggested a 90 °F 

condenser air entering dry bulb 

temperature in its waiver request; 

however, the company did not provide 

technical justification for this request, 

and DOE has determined that outdoor 

wine cellar refrigeration units must be 

tested at 95 °F, 59 °F, and 35 °F, 

consistent with the current DOE test 

procedure. 

For the reasons explained in the 

Notification of Petition for Waiver, the 

Order does not include a 0.55 correction 

factor in the alternate test procedure as 

suggested by Vinotemp. 86 FR 23692, 

23697–23698. The company had 

observed that the test procedure in 

appendix A to subpart B of 10 CFR part 

430 (‘‘Appendix A’’), which applies to 

miscellaneous refrigeration products, 

includes such a factor to adjust for 

average use, and sought to include such 

a factor as part of its petition. As 

explained in the Notice of Petition for 

Waiver, the closed-door conditions on 

which the miscellaneous refrigeration 

correction factor is based are not present 

in the test procedure for walk-in cooler 

refrigeration systems, and the referenced 

AHRI 1250–2009 provisions assume a 

load factor of 50 percent, consistent 

with Appendix C. Id. As a result, 

applying the 0.55 correction factor as 

suggested by Vinotemp is not 

appropriate for the specified basic 

models. 

DOE is requiring that Vinotemp test 

and rate specified wine cellar walk-in 

refrigeration system basic models 

according to the alternate test procedure 

specified in this Decision and Order. 

This alternate procedure is a modified 

version of the one suggested by 

Vinotemp. The alternate test procedure 

required under this Order is the same 

alternate test procedure prescribed in 

the Interim Waiver Order. 

This Decision and Order applies only 

to the basic models listed and does not 

extend to any other basic models. DOE 

evaluates and grants waivers for only 

those basic models specifically set out 

in the petition, not future models that 

may be manufactured by the petitioner. 

Vinotemp may request that DOE extend 

the scope of this waiver to include 

additional basic models that employ the 

same technology as those listed in this 

waiver. 10 CFR 431.401(g). Vinotemp 

may also submit another petition for 

waiver from the test procedure for 

additional basic models that employ a 

different technology and meet the 

criteria for test procedure waivers. 10 

CFR 431.401(a)(1). 

DOE notes that it may modify or 

rescind the waiver at any time upon 

DOE’s determination that the factual 

basis underlying the petition for waiver 

is incorrect, or upon a determination 

that the results from the alternate test 

procedure are unrepresentative of the 

basic models’ true energy consumption 

characteristics. 10 CFR 431.401(k)(1). 

Likewise, Vinotemp may request that 

DOE rescind or modify the waiver if the 

company discovers an error in the 

information provided to DOE as part of 

its petition, determines that the waiver 

is no longer needed, or for other 

appropriate reasons. 10 CFR 

431.401(k)(2). 

As set forth previously, the test 

procedure specified in this Decision and 

Order is not the same as the test 

procedure suggested by Vinotemp. If 

Vinotemp believes that the alternate test 

method it suggested provides 

representative results and is less 

burdensome than the test method 

required by this Decision and Order, 

Vinotemp may submit a request for 

modification under 10 CFR 

431.401(k)(2) that addresses the 

concerns that DOE has specified with 

that procedure. Vinotemp may also 

submit another less burdensome 

alternative test procedure not expressly 

considered in this notification under the 

same provision. 

III. Order 

After careful consideration of all the 

material that was submitted by 

Vinotemp, the various public-facing 

materials (e.g., marketing materials, 

product specification sheets, and 

installation manuals) for the units 

identified in the petition, information 

provided by Vinotemp and other wine 

cellar walk-in refrigeration system 

manufacturers in meetings with DOE, 

and the comment received, in this 

matter, it is ordered that: 

(1) Vinotemp must, as of the date of 

publication of this Order in the Federal 

Register, test and rate the following 

Wine Mate-branded wine cellar walk-in 

cooler refrigeration system basic models 

with the alternate test procedure as set 

forth in paragraph (2):

Federal Register / Vol. 86, No. 131 / Tuesday, July 13, 2021 / Notices 36737 

Section C3.5 of AHRI 1250–2009 is revised 

to read: 

Unit Cooler Fan Power Measurement. The 

following shall be measured and recorded 

during a fan power test. 

EFcomp,on Total electrical power input to fan 

motor(s) of Unit Cooler, W 

FS Fan speed (s), rpm 

N Number of motors 

Pb Barometric pressure, in. Hg 

Tdb Dry-bulb temperature of air at inlet, °F 

Twb Wet-bulb temperature of air at inlet, °F 

V Voltage of each phase, V 

For a given motor winding configuration, 

the total power input shall be measured at 

the highest nameplated voltage. For threephase power, voltage imbalance shall be no 

more than 2%. 

3.3.3.2 Evaporator fan power for the offcycle is equal to the on-cycle evaporator fan 

power with a run time of ten percent of the 

off-cycle time. 

EFcomp,off = 0.1 × EFcomp,on

In Appendix C to Subpart R, 

following section 3.3.7.2, add new 

sections 3.3.8, 3.3.9, and 3.3.10 to read: 

3.3.8. Measure power and capacity of 

single-packaged dedicated systems as 

described in sections C4.1.2 and C9 of AHRI 

1250–2020. The third and fourth sentences of 

Section C9.1.1.1 of AHRI 1250–2020 

(‘‘Entering air is to be sufficiently dry as to 

not produce frost on the Unit Cooler coil. 

Therefore, only sensible capacity measured 

by dry bulb change shall be used to calculate 

capacity.’’) shall not apply. 

3.3.9. For systems with ducted evaporator 

air, or that can be installed with or without 

ducted evaporator air: Connect ductwork on 

both the inlet and outlet connections and 

determine external static pressure as 

described in ASHRAE 37–2009, sections 6.4 

and 6.5. Use pressure measurement 

instrumentation as described in ASHRAE 37– 

2009 section 5.3.2. Test at the fan speed 

specified in manufacturer installation 

instructions—if there is more than one fan 

speed setting and the installation instructions 

do not specify which speed to use, test at the 

highest speed. Conduct tests with the 

external static pressure equal to 50 percent of 

the maximum external static pressure 

allowed by the manufacturer for system 

installation within a tolerance of –0.00/+0.05 

in. wc. If testing with the indoor air enthalpy 

method, adjust the airflow measurement 

apparatus fan to set the external static 

pressure—otherwise, set the external static 

pressure by symmetrically restricting the 

outlet of the test duct. In case of conflict, 

these requirements for setting evaporator 

airflow take precedence over airflow values 

specified in manufacturer installation 

instructions or product literature. 

3.3.10. For systems with ducted 

condenser air, or that can be installed with 

or without ducted condenser air: Connect 

ductwork on both the inlet and outlet 

connections and determine external static 

pressure as described in ASHRAE 37–2009, 

sections 6.4 and 6.5. Use pressure 

measurement instrumentation as described in 

ASHRAE 37–2009 section 5.3.2. Test at the 

fan speed specified in manufacturer 

installation instructions—if there is more 

than one fan speed setting and the 

installation instructions do not specify which 

speed to use, test at the highest speed. 

Conduct tests with the external static 

pressure equal to 50 percent of the maximum 

external static pressure allowed by the 

manufacturer for system installation within a 

tolerance of –0.00/+0.05 in. wc. If testing 

with the outdoor enthalpy method, adjust the 

airflow measurement apparatus fan to set the 

external static pressure—otherwise, set the 

external static pressure by symmetrically 

restricting the outlet of the test duct. In case 

of conflict, these requirements for setting 

condenser airflow take precedence over 

airflow values specified in manufacturer 

installation instructions or product literature. 

If testing using the outdoor air enthalpy 

method, the requirements of section 8.6 of 

ASHRAE 37–2009 are not applicable. 

In Appendix C to Subpart R, revise 

section 3.3.6 (which specifies 

modifications to AHRI 1250–2009) to 

read: 

3.3.6. AWEF is calculated on the basis that 

walk-in box load is equal to half of the 

system net capacity, without variation 

according to high and low load periods and 

without variation with outdoor air 

temperature for outdoor refrigeration 

systems, and the test must be done as a 

matched or single-package refrigeration 

system, as follows:

(3) Representations. Vinotemp may 

not make representations about the 

efficiency of a basic model listed in 

paragraph (1) of this Order for 

compliance, marketing, or other 

purposes unless the basic model has 

been tested in accordance with the 

provisions set forth above and such 

representations fairly disclose the 

results of such testing. 

(4) This waiver shall remain in effect 

according to the provisions of 10 CFR 

431.401. 

(5) This Order is issued on the 

condition that the statements, 

representations, and information 

provided by Vinotemp are valid. If 

Vinotemp makes any modifications to 

the controls or configurations of a basic 

model subject to this Order, such 

modifications will render the waiver 

invalid with respect to that basic model, 

and Vinotemp will either be required to 

use the current Federal test method or 

submit a new application for a test 

procedure waiver. 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 431.401(k)(1). 

Likewise, Vinotemp may request that 

DOE rescind or modify the waiver if 

Vinotemp discovers an error in the 

information provided to DOE as part of 

its petition, determines that the waiver 

is no longer needed, or for other 

appropriate reasons. 10 CFR 

431.401(k)(2). 

(6) Vinotemp remains obligated to 

fulfill any applicable 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. 

Vinotemp may submit a new or 

amended petition for waiver and request 

for grant of interim waiver, as 

appropriate, for additional basic models 

of walk-in cooler refrigeration systems. 

Alternatively, if appropriate, Vinotemp 

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 

431.401(g).

[Docket No. CP18–103–000] 

Rockies Express Pipeline LLC; Notice 

of Extension of Time Request 

Take notice that on June 23, 2021, 

Rockies Express Pipeline LLC (Rockies 

Express) requested that the Federal 

Energy Regulatory Commission 

(Commission) grant an extension of 

time, until September 20, 2023, to 

complete the construction of six new 

5,350 horsepower (hp) natural gas 

reciprocating compressor units (32,100 

hp total) at its existing Cheyenne 

Compressor Station (Cheyenne Hub 

Enhancement Project) in Weld County, 

Colorado, as authorized as part of the 

Cheyenne Hub Enhancement Project in 

the September 20, 2019 Order Issuing 

Certificates 1 (September 20 Order). The 

September 20 Order required Rockies 

Express to complete construction and 

make the facilities available for service 

within two years of the Order date. 

Rockies Express has since completed 

construction of four of the six 

authorized compressor units, placing 

units 1–3 into service on July 26, 2020,2

and unit 4 into service on December 17, 

2020.3 Compressor units 5 and 6 remain 

unconstructed. 

Rockies Express states it has been 

delayed in reaching full 

commercialization for compressor units 

5 and 6, with the economic slowdown 

and fallout from the COVID–19 

pandemic. The final two compressor 

units that have not yet been constructed 

will be installed at the existing 

Cheyenne Compressor Station on land 

already owned by Rockies Express 

under the terms and conditions of the 

existing certificate. Rockies Express 

states that the extension of time will not 

result in any environmental impacts not 

already examined on the record in the 

certificate proceeding and will provide 

Rockies Express with the time necessary 

to install these remaining two units. 

This notice establishes a 15-calendar 

day intervention and comment period 

deadline. Any person wishing to 

comment on Rockies Express’ request 

for an extension of time may do so. No
