Agency Response Pending the update of the Enforcement Policy and Dated April 24, 2024: Enforcement Manual, ensure the periodically updated NMSS supplemental guidance is readily accessible and is available to all staff responsible for Part 37 enforcement activities. NRC staff uses the informal guidance in the nonpublic NMSS memo issued January 5, 2018, to support determining the severity level of Part 37 violations. A link to the memo has been placed in the Material Security Toolbox to ensure it is readily accessible and available to NRC staff responsible for Part 37 inspection and enforcement activities. NMSS/Division of Materials Safety, Security, State, and Tribal Programs (MSST) staff provides access to the protected, non-public information in the Material Security Toolbox. The NMSS memo was also placed in the Repository of Communication with Regions hosted in the MSST/Materials Safety Licensing Branch SharePoint site. Target Completion Date: The NRC staff recommends closure of this item. OIG Analysis: The OIG reviewed the memo’s location on the NMSS SharePoint site and the Materials Security Toolbox. We understand that this is a temporary measure to make Part 37 information more available to relevant staff until to the Enforcement Policy and Enforcement Manual revisions are completed. This recommendation is now closed. https://adamsxt.nrc.gov/navigator/AdamsXT/content/downloadContent.faces?objectStoreName=MainLibrary&vsId=%7bACB33374-17F1-C1B5-97D5-8FAADA300000%7d&ForceBrowserDownloadMgrPrompt=false
