Federal Register / Vol. 86, No. 203 / Monday, October 25, 2021 / Rules and Regulations Sections 6c3 and 7b of the Process Rule.
In sum, if DOE determines that a technology, or a combination of technologies, fails to meet one or more of the listed five criteria, it will be excluded from further consideration in the engineering analysis. The reasons for eliminating any technology are discussed in the following sections.
DOE evaluated of each the technology options against the screening analysis criteria and determined whether it should be excluded screened out based on the screening criteria. DOE did not receive comments on technology options screened out in the August 2020
NOPD and therefore screened out the same technology options in this final determination.
a. Screened-Out Technologies For magnetic ballasts, DOE screened out the technology option of using laminated sheets of amorphous steel.
DOE determined that using amorphous steel could have adverse impacts on consumer utility because increasing the size and weight of the ballast may limit the places a customer could use the ballast. 85 FR 47472, 47484.
b. Remaining Technologies

DOE concludes that all of the other identified technologies listed in section IV.B.4 met all five screening criteria to be examined further as design options in DOEs final determination. In summary, DOE did not screen out the following technology options:

b Magnetic Ballasts Improved Core Steel Copper Wiring Improved Steel Laminations Improved Windings Electronic Ballast b Electronic Ballasts Improved Components Improved Circuit Design 85 FR 47472, 47485.
DOE determined that these technology options are technologically feasible because they are being used or have previously been used in commercially-available products or working prototypes. DOE also finds that all of the remaining technology options meet the other screening criteria i.e., practicable to manufacture, install, and service; do not result in adverse impacts on consumer utility, product availability, health, or safety; and do not utilize proprietary technology. For additional details, see chapter 4 of the final determination TSD.
C. Engineering Analysis In the engineering analysis, DOE
develops cost-efficiency relationships characterizing the incremental costs of achieving increased ballast efficiency.
This relationship serves as the basis for cost-benefit calculations for individual consumers and the nation. The methodology for the engineering analysis consists of the following steps:
1 Selecting representative equipment classes; 2 selecting baseline metal halide ballasts; 3 identifying more efficient substitutes; 4 developing

efficiency levels; and 5 scaling efficiency levels to non-representative equipment classes. The details of the engineering analysis are discussed in chapter 5 of the final determination TSD.
1. Representative Equipment Classes DOE selects certain equipment classes as representative to focus its analysis.
DOE chooses equipment classes as representative primarily because of their high market volumes and/or unique characteristics. DOE established 24
equipment classes based on input voltage, rated lamp wattage, and indoor/
outdoor designation. DOE did not directly analyze the equipment classes containing only fixtures with ballasts tested at 480 V due to low shipment volumes. DOE selected all other equipment classes as representative, resulting in a total of 12 representative classes covering the full range of lamp wattages, as well as indoor and outdoor designations. 76 FR 47472, 47485
47486.
In the August 2020 NOPD DOE
directly analyzed the equipment classes shown in gray in Table IV.3 of this document. 76 FR 47472, 4748547486.
DOE did not receive any comments on the representative product classes presented in the August 2020 NOPD.
Therefore, DOE continues to analyze the representative product classes shown in gray in Table IV.3 in this final determination.
