ences are determined. It provides specific interim guidance on implementing Sections 2.4.12, 2.4.13, 11.2, and BTP 11-6 of NUREG-0800. • DC/COL-ISG-014, “Assessing the Radiological Consequences of Accidental Releases of Radioactive Materials from Liquid Waste Tanks in Ground and Surface Waters for Combined License Applications” (Ref. 12), provides interim guidance to licensees and NRC staff on analyzing the accidental releases of radioactivity in ground and surface water. It emphasizes the consideration of hydrogeologic conditions that control the transport of radioactive materials and provides specific interim guidance on implementing Sections 2.4.12, 2.4.13, 11.2, and BTP 11-6 of NUREG-0800. • NUREG/CR-6948, Volume 1, “Integrated Ground-Water Monitoring Strategy for NRC Licensed Facilities and Sites: Logic, Strategic Approach and Discussion” (Ref. 13), presents a framework for assessing what, how, where and when to monitor ground water to ensure that a licensed nuclear site or facility is within regulatory limits. Purpose of Regulatory Guides The NRC issues RGs to describe to the public methods that the staff considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific problems or postulated events, and to provide guidance to applicants. Regulatory guides are not substitutes for regulations and compliance with them is not required. Methods and solutions that differ from those set forth in RGs will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission.
