tions 3.2.1, 3.2.2, 3.3.1, 3.3.2, 3.5.3, 3.7.1 through 3.7.4, 3.8.4, and 3.8.5 will be used to evaluate exceptions. 6. The LWMS is reviewed to ensure that the design includes provisions to prevent and collect leakage resulting from overflows and spillage from indoor and outdoor storage tanks containing liquids and liquid wastes, and meets the requirements of 10 CFR 20.1406. The review will confirm that: A. Adequate design features exist, supplemented with operating programs, processes and procedures (as necessary), and these provide reasonable assurance that spills, leaks, and inadvertent discharges of radioactive liquid waste or effluents will be prevented or minimized. B. In the event that a spill, leak, or inadvertent discharge does occur, the staff should 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 11.2-24 Draft Revision 5 – August 2014 observation, leak detection capability, to the extent practical, should allow for the identification and measurement of relatively small leak rates (e.g., several gallons per week), depending on the concentration of radioactive materials and leak/spill rates. C. Design features are supplemented, as necessary, by operating programs, processes, and procedures to monitor spills and leaks and evaluate their impact to the environment and prevent uncontrolled and unmonitored radioactive releases to underlying soils, surface water bodies, and groundwater. D. The site has been adequately characterized and conceptual site models have been developed which define the site hydrogeological settings, including subsurface and surface migration pathways under both pre-construction and post-construction conditions. These models are needed to assist with the design of surface and groundwater monitoring and procedures, design of protective measures, carrying out remediation, and the planning of decommissioning activities.
