appendix D1 and section 1.19 of appendix D2 provided a definition for temperature sensing control. 51 Both of these definitions were obsolete, having been incorporated into a broader term automatic termination control 52
in section 1.4 of both appendices as part of the January 2011 Final Rule. 76 FR
972, 978 Jan. 6, 2011. In addition, the terms moisture sensing control and temperature sensing control were not referenced anywhere else within appendix D1 or appendix D2. DOE is removing these definitions from both appendices and renumbering the subsequent sections of the test procedure accordingly.
Section 3.5 of appendix D2 described the application of a field use factor for clothes dryers with automatic termination controls. In the August 2013
Final Rule, DOE eliminated the field use factor in appendix D2 for automatic termination control clothes dryers, in conjunction with new procedures that directly measure any over-drying energy consumption of automatic termination control clothes dryers. 78 FR 49608, 49611 Aug. 14, 2013. In the August 2013 Final Rule, DOE erroneously retained the obsolete section 3.5 of appendix D2. DOE therefore is removing section 3.5 of appendix D2 and adjusting the numbering of subsequent sections accordingly.
Section 4.7 of both appendix D1 and appendix D2 provided the equation for calculating EF. DOEs energy conservation standards for clothes dryers were based on energy factor EF for clothes dryers manufactured on or after May 14, 1994 and before January 1, 2015. However, as of January 1, 2015, clothes dryer energy conservation standards are based on the CEF metric. Similarly, DOEs certification reporting requirements for clothes dryers at 10 CFR 429.21b2
required reporting CEF when using appendix D1 or appendix D2; EF was required only when using appendix D, which is obsolete and is removed in this final rule. Furthermore, ENERGY STAR

51 Temperature sensing control is defined as a system which monitors dryer exhaust air temperature and automatically terminates the dryer cycle.
52 Automatic termination control is defined as a dryer control system with a sensor which monitors either the dryer load temperature or its moisture content and with a controller which automatically terminates the drying process. A
mark, detent, or other visual indicator or detent which indicates a preferred automatic termination control setting must be present if the dryer is to be classified as having an automatic termination control. A mark is a visible single control setting on one or more dryer controls.

qualification is based on the CEF metric.
DOE is not aware of any current regulatory programs or criteria that use the EF metric. Therefore, DOE is removing the obsolete calculation of EF
in section 4.7 of both appendix D1 and appendix D2, renumbering the subsequent sections of the test procedures accordingly, and removing EF as a measure of energy consumption described at 10 CFR 430.23d2.
F. Removing Obsolete Appendix D
In the July 2019 NOPR, DOE proposed to remove appendix D from 10 CFR part 430, since this version of the test procedure is no longer used. DOE also proposed to remove the references to appendix D from 10 CFR 430.23d, as well as in the clothes dryer certification reporting requirements in 10 CFR
429.21b2.
AHAM stated that it did not oppose DOEs proposal to remove appendix D, because this appendix is no longer mandatory. AHAM, No. 33 at p. 11 No other comments were received on the removal of appendix D.
Given that appendix D is no longer in use, DOE is removing appendix D and all associated references throughout 10
CFR 429.21 and 10 CFR 430.23d.
G. Test Procedure Costs and Impact EPCA requires that test procedures adopted by DOE not be unduly burdensome to conduct. In this document, DOE amends the existing test procedure for residential clothes dryers.
DOE has determined that the test procedure as amended by this final rule will not be unduly burdensome for manufacturers to conduct.
In this final rule, DOE adopts a number of amendments to both appendix D1 and appendix D2. The current energy conservation standards for clothes dryers were developed based on results obtained using appendix D1.
As discussed in the following sections, neither the amendments to appendix D1
or appendix D2 will impact the current costs of the test procedures.
None of the amendments to appendix D1 or appendix D2 will impact the scope of the test procedure i.e., the amendments will not require manufacturers to test clothes dryers that are not already required to be tested.
Additionally, DOE has determined that none of the amendments will require manufacturers to re-test or re-certify any existing models on the market that have been tested and certified using appendix D1 or appendix D2.
Based on the discussion that follows, DOE has determined that these amendments to the clothes dryer test procedure in appendix D1 and appendix

D2 will not be unduly burdensome for manufacturers to conduct.
1. Maintaining Hourly Btu Rating for Gas Clothes Dryers DOE specifies the order of adjustment, from least burdensome to most burdensome, for the three types of adjustments that can be made to maintain the required heat input rate for natural gas and propane clothes dryers.
As described, this amendment is generally consistent with industry practice. To the extent that any deviations from this order may occur in practice, the additional direction provided by these amendments will not require any manufacturers to retest or re-certify any basic models currently on the market because the net result of maintaining the hourly Btu rating within 5 percent of the rated value will not change. Therefore, drying performance will not be impacted in comparison to results obtained under the previous test procedures.
2. Final Moisture Content Requirement DOE explicitly specifies that any second test run using the highest dryness level setting must result in an FMC of 2 percent or less for the test to be considered valid. This amendment impacts only appendix D2, and therefore has no impact on testing under appendix D1. As described, this amendment reflects the current practice of manufacturers and test laboratories, and therefore does not impact the cost of testing.
3. Additional Amendments DOE has determined that the remainder of the amendments adopted in this final rule will not impact test costs.
DOE provides direction regarding the required settings for network capabilities during testing under both appendix D1 and appendix D2. This direction will not impact test costs as it provides further direction to the prior test procedure and does not require conducting an additional test. The amendment will not change the measured energy use of basic models for which the consumer is required to turn on the network capability, as the prior test procedure provided no direction to do so. To the extent that there are basic models with the network capability enabled in the as shipped condition, the energy use attributable to the network function would have been captured under the prior test procedure. For any such basic models, the direction regarding the network capabilities adopted in this document will result in lower measured energy use as compared
