verify that there is reasonable assurance that it will be detected in a timely manner. For those SSCs that are typically inaccessible for routine inspection or observation, leak detection capability, to the extent practical, should allow for the identification and measurement of relatively small leak rates, depending on the concentration (e.g. several gallons per week). • Design features should be supplemented, as necessary, by operating programs, processes and procedures to monitor spills and leaks and evaluate their impact to the environment. • The site has been adequately characterized and conceptual site models have been developed which define the site hydro geological setting including subsurface and surface migration pathways under both pre-construction and post-construction A-3 conditions. These models are needed to assist with designing monitoring components and procedures, designing protective measures, carrying out remediation, and designing decommissioning activities. • Design features that facilitate decommissioning (such as modular components and adequate space for equipment removal) should be described, and their role in the decommissioning process should be described. Operating procedures to minimize the amount of residual radioactivity that will require remediation at the time of decommissioning should also be described. • The site has been designed and will be operated to minimize the generation and volume of radioactive waste, both during operation and during decommissioning. The NRC staff’s safety evaluation report (SER) related to NEI technical report NEI 08-08A “Guidance for Life Cycle Minimization of Contamination” (ADAMS Accession Number ML093220530) provides the bases for the use of the template to describe an acceptable operational Ground Water Protection program which conforms to the guidance of RG 4.21. For those licensees that elect to demonstrate compliance with the programmatic requirements of 10 CFR 20.1406 via alternate
