endix 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 operational events over the lifetime of the facility, in accordance with applicable information collection requirements such as 10 CFR 70.50, “Reporting Requirements”; and Subpart D, “Records, Reports, Inspections, and Enforcement,” of 10 CFR Part 72, “Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste, and Reactor- Related Greater than Class C Waste.” In addition, 10 CFR 30.35(g), 10 CFR 40.36(f), 10 CFR 50.75(g), 10 CFR 70.25(g), and 10 CFR 72.30(d) have recordkeeping requirements important to decommissioning. This program can provide information that will be important in preparing an historical assessment of a nuclear facility, which can save time and effort during decommissioning planning. c. Decommissioning activities in the past have been complicated by radioactivity that was not adequately documented before decommissioning began. Applicants covered by 10 CFR 20.1406 are encouraged to consider maintaining records of instances of facility and environmental contamination events that result in residual contamination that may complicate the decommissioning process. d. Plans and procedures to facilitate decommissioning should include (1) comprehensive video records of the equipment layout in areas where radiation fields are expected to be high following operations, and (2) as-built drawings of the facility. Furthermore, the records should include global positioning system readings that pinpoint all buried component locations, particularly components in the site environs. However, it is recognized that obtaining reliable ground positioning system readings within certain SSCs is not practical because of structural interference with signal quality. e. Facility designs should minimize the use of embedded
