## II. Discussion

On December 17, 2020, the NRC solicited comments on DG-1361. The public comment period closed on February 16, 2021. DG-1361 is proposed revision 2 of regulatory guide (RG) 1.89 of the same name. The proposed revision describes an approach that is acceptable to the staff of the NRC to meet regulatory requirements for environmental qualification of certain electric equipment important to safety for nuclear power plants. The previous revision of RG 1.89 was issued in June 1984 and endorsed the use of Institute of Electrical and Electronic Engineers (IEEE) Standard (Std.) 323-1974. This proposed revision incorporates additional information regarding the dual logo International Electrotechnical Commission (IEC)/IEEE Std. 60780-323, “Nuclear Facilities—Electrical Equipment Important to Safety—Qualification,” Edition 1, 2016-02. The NRC received two requests to extend the public comment period (ADAMS Accession Nos. ML20142A003 and ML21041A128), but the agency was unable to extend the comment period before the close of the comment period. The NRC has decided to reopen the public comment period for an additional 60 days to allow more time for members of the public to develop and submit their comments.
