Content:
efore the selection of a remediation strategy. w. When deemed appropriate, ground-water capture zones surrounding SSCs should be designed and operated to provide effective means to isolate and collect liquid contaminants escaping to the subsurface. Groundwater and/or soil remediation will not be necessary for every detection of contamination. A risk-informed approach may be implemented to assess the applicable site- specific parameters (e.g., kind of facility, materials, and hazards involved) for consideration in decommissioning activities. x. In general, onsite disposal of radioactive material [i.e., disposal of waste under Title 10, Section 20.2002, “Method for Obtaining Approval of Proposed Disposal Procedures,” of the Code of Federal Regulations (10 CFR 20.2002)], should be avoided or minimized as described in a license application. Such disposals should be located in areas not susceptible to surface-water flooding or occasional water-table rise creating local saturation of the waste, and they must have proper monitoring to detect potential radionuclide migration. If the applicant chooses to pursue waste disposal under 10 CFR 20.2002, all the required documentation relating to onsite disposal should be maintained in the facility records until the license is terminated. A-3. Facilitating Decommissioning To facilitate decommissioning, 10 CFR 20.1406 applicants should consider the following specific measures (or a combination thereof): a. To facilitate decommissioning, all information relating to the facility design, facility construction, facility design changes, site conditions before and after construction, onsite waste disposal, onsite contamination, and results of monitoring and radiological surveys should be centrally located and readily recoverable. Appendix A to RG 4.21, Page A-6 b. Applicants should establish procedures to ensure adequate and complete documentation of corporate knowledge of instances of facility and environmental contamination and
