Dear Mr. Beyreis: This is in response to your letter dated March 5, 2002, which addresses recognition of the Underwriters Laboratories Inc. (UL) Energy Verification Service (EVS) for electric motor efficiency as a nationally recognized certification program under the provisions of section 431.27 of Title 10 Code of Federal Regulations Part 431 (10 CFR 431), and your concern about completion of the recognition process. I understand your concern and I can assure you that the Department of Energy (the Department) has been diligent in properly handling all documents and information provided by UL to ensure the integrity of the process. In general, the Department has been supportive of the UL EVS for motor efficiency and hks been working with UL in the mutual hope of a satisfactory determination. Notwithstanding, the evidence provided by UL to support its petition for national recognition has been weak and has contained defects. Also, public comments received as a result of publication of the UL Petition in the Federal Register (66 FR 50355 (October 3, 2001)) were critical of the UL EVS for motor efficiency. The Department pointed out to UL these defects in an effort to correct them. Examples are as follows: • Section 431.27(b)(1) of 10 CFR 431 requires "satisfactory standards and procedures for conducting and administering a certification system." Initial EVS motor efficiency guides and manuals submitted by UL contained inaccurate information concerning compliance with the energy efficiency levels contained in 10 CFR 431 and cited an obsolete test .procedure. • Section 431(b)(3) of 10 CFR 431 requires a certification system to "operate in a highly competent manner." On September 20, 20002, UL submitted to the Department an automated spreadsheet program as an example of its ability to take test data and enter it into a software program that would be used to calculate energy efficiency, and thereby "avoid errors common to data-intensive calculations." The Department examined the spreadsheet and found that the data sheet failed to correctly report a number of critical data points required to properly determine the efficiency of a motor. UL acknowledged the errors, made corrections and resubmitted its spreadsheet. Again, the Department found errors. This problem with the data sheet has caused concern as to whether UL has :satisfactory standards and procedures in place for conducting and administering its EVS for motors. Further, we would expect technical staff familiar with the IEEE Standard
