**II. Discussion**
On February 21, 2023, the NRC published a document in the *Federal Register* (88 FR 10481) soliciting comments on DG-5065, “Perimeter Intrusion Alarm Systems” (ADAMS Accession No. ML22194A912). This DG provides implementing guidance acceptable to the NRC staff for meeting requirements in NRC regulations related to the functions of perimeter intrusion detection sensors and detection methods. The DG provides guidance on sensors and methods that can be integrated to form an effective perimeter intrusion detection system. In addition, the DG provides guidance on selecting perimeter intrusion detection systems and on applications for nuclear power reactors, independent spent fuel storage installations, and certain special nuclear material processing facilities. The comment period was originally scheduled to close on March 23, 2023. Upon the request of the Nuclear Energy Institute, the NRC has decided to extend the public comment period on this document until May 22, 2023, to allow more time for members of the public to submit their comments.
As noted in the *Federal Register* on December 9, 2022 (87 FR 75671), this document is being published in the “Proposed Rules” section of the *Federal Register* to comply with publication requirements under chapter 1 of title I of the *Code of Federal Regulations.*
