data to make a determination of the long- term representativeness of meteorological conditions in the facility’s site. With respect to this determination, other NRC documents include more up-to-date guidance. Such documents include: 1) NUREG-1567, “Standard Review Plan for Spent Fuel Dry Storage Facilities,” issued in 2000, 2) NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,” Section 2.3.2, Local Meteorology, Revision 3, and Section 2.3.3, Onsite Meteorological Measurements Program, Revision 3, 2007, and 4) RG 1.23, “Meteorological Monitoring Programs for Nuclear Power Plants,” Revision 1, 2007. These documents list industry standards to address the representativeness of short-term meteorological records such as: 1) the American National Standards Institute/American Nuclear Society (ANSI/ANS)-2.15-2013, “Criteria for Modeling and Calculating Atmospheric Dispersion of Routine Radiological Releases From Nuclear Facilities,” and 2) ANSI/ANS-3.11-2015, “Determining Meteorological Information at Nuclear Facilities,” using a minimum period of record instead of a statistical analysis of the meteorological data.” 2. What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years? RG 3.63 has no impact on licensing and inspection activities since the NRC staff is not expecting any new or renewal applications in the next several years. 5 3. What is an estimate of the level of effort needed to address identified issues in terms of full-time equivalent (FTE) and contractor resources? An estimate of the effort needed to correct the identified issues is between 1-and2 FTE. 4. Based on the answers to the questions above, what is the NRC staff action for this guide (Reviewed with no issues identified, Reviewed with issues identified for future consideration, Revise, or
