door. The 120-cycle estimate is consistent with the value relied on by DOE in its evaluation of potential test procedure provisions to address door opening infiltration in the test procedure supplemental notice of proposed rulemaking published September 9, 2010. 75 FR 55068, 55085.6
The first example provided by Hercules was the Single Slide Electric Horizontal Sliding Door, which has a maximum opening of 288 inches operating at a speed of 10 inches per second IPS in both directions.
Hercules, No. 2 at p. 2 For this example, the normal daily use cycle estimate and cycle time estimate result in a total motor run time of 115.2
minutes 1.92 hours per day, leaving the door motor out of operation for 22.08 hours per day, or 92 PTO. Id.
The second example provided by Hercules was the Bi-Parting Electric Horizontal Sliding Door, which has a maximum opening of 288 inches operating at a speed of 10 IPS in both directions for each door. Id. Because the motor operator controls the movement of two doors at once, the cycle time is half of what it was for the Single Slide Electric Horizontal Sliding Door example. This results in an estimated total motor run time of 57.6 minutes 0.96 hours per day, leaving the door motor out of operation for 23.04 hours per day, or 96 PTO. Id.
The third example provided by Hercules was the Electric Vertical Lift door, which has a maximum vertical opening of 288 inches operating at a speed of 12 IPS in both directions.
Hercules, No. 2 at p. 3. For this example, the normal daily use cycle estimate and cycle time estimate result in a total run time of 96 minutes 1.6
hours per day, leaving the door motor out of operation for 22.4 hours per day, or 93.3 PTO.
Based on these calculations, Hercules petitioned DOE to apply a PTO value of 92 percent for the specified basic models of their walk-in doors that use electric door motors. Id.
Hercules also requested 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 immediate relief pending a 6 DOE did not adopt test procedure provisions addressing door opening infiltration, having determined that a typical door manufacturer has very few direct means for reducing the door infiltration on its own. 73 FR 21580, 21595 Apr.

determination of the petition for waiver.
See 10 CFR 431.401e2.
Based on the assertions in the petition, absent an interim waiver, the walk-in door basic models with electric door motors identified in Herculess October 2020 petition for a waiver cannot be tested and rated for energy consumption on a basis representative of their actual energy consumption characteristics.
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 equipment. 42 U.S.C.
6314d Consistency is important when making representations about the energy efficiency of covered equipment, including when demonstrating compliance with applicable DOE energy conservation standards. Pursuant to its regulations at 10 CFR 430.401, 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 models addressed by the Interim Waiver Order.
Hercules seeks to use an alternate test procedure to test and rate specific walkin door basic models. Instead of using the PTO value of 25 percent established in section 4.5.2a3 of Appendix A for electricity-consuming devices other than lighting and anti-sweat heaters, Hercules requests using the minimum calculated PTO value in their petition, 92 percent, for all of their specified models.
VI. Interim Waiver Order DOE has reviewed Herculess application for an interim waiver, the alternate test procedure requested by Hercules, and the data provided by Hercules in both its original July 2020
petition and the October 2020 petition, along with material on its website. As part of DOEs review, DOE considered the potential range of parameters affecting door motor operating time, including door opening width or height, speed of door closing/opening, and cycles per day.
DOE examined the operating conditions specified in Herculess petition and compared them with the values mentioned in the product literature. Specifically, DOE compared the minimum operating speed of the motor and maximum length or height of the door opening to assess if the most energy consumptive scenario was captured in the PTO value requested.
Based on DOEs review of the manufacturer materials, the examples

provided by Hercules in the October 2020 petition and the associated calculations are the most energy consumptive scenarios for the basic models specified by Hercules i.e., the single-slide electric horizontal sliding door basic models beginning with EHS
D, the bi-parting electric horizontal sliding door basic models beginning with EBPD, and the electric vertical lifting door basic models beginning with EVLD. DOE then validated these calculations.
Based on DOEs review, Herculess suggested alternate test procedure that applies a PTO value of 92 percent appears to allow for the accurate measurement of the energy consumption of the specified basic models, while alleviating the testing issues associated with Herculess implementation of walk-in door testing for these basic models. The required use of a PTO value of 92 percent is consistent with waivers previously granted in response to petitions that presented the same issue as in Herculess petition.7 Consequently, DOE
has determined that Herculess petition for waiver will likely be granted.
Furthermore, DOE has determined that it is desirable for public policy reasons to grant Hercules immediate relief pending a determination of the petition for waiver.
For the reasons stated, it is ordered that:
1 Hercules must test and rate the Hercules brand basic models listed in Appendix I of its October 14, 2020
petition as provided in Docket Number EERE2020BTWAV0027 8 with the alternate test procedure set forth in paragraph 2.
2 The alternate test procedure for the Hercules basic models identified in paragraph 1 of this Interim Waiver Order is the test procedure for walk-in doors prescribed by DOE at 10 CFR part 431, subpart R, appendix A, except that the percent time off PTO value specified in section 4.5.2 Direct Energy Consumption of Electrical Components of Non-Display Doors shall be 92
percent for door motors. All other requirements of 10 CFR part 431, subpart R, appendix A and DOEs regulations remain applicable.
