ed to possess. Licensees can meet the financial assurance requirements either by the methods specified in those regulations, or by a site-specific estimate. If a licensee’s possession limit does not require it to have financial assurance, the DPR does not require the licensee to perform any further action because the potential for significant residual radioactivity is low. These licensees should continue executing the existing ALARA and health and safety programs as discussed in Figure 3b. If, however, regulations do require financial assurance, either by formula or by site-specific estimate, the licensee must determine if there have been previous spills or leaks during the operating history of the site. Also, the licensee must identify the potential for such events to occur in the future. Staff experience (Ref. 9) shows that the presence of liquid or gaseous processes presents the possibility of unplanned or unmonitored releases. Further, after planned discharges within regulatory limits, fluids can concentrate in various locations to greater than release limits. Therefore, if fluids are part of the operations at the site, licensees should conduct a more detailed review of monitoring and survey plans to ensure that they will identify the sources and extent of future leaks or spills. The outflow of hoods, which can move particulates beyond the facility, should also be considered. The amount of review depends on the complexity of the process and facility, and on the potential release. If there are no fluids in the site processes, no further review is required by the DPR, and licensees should continue implementing existing plans as illustrated in Figure 3b. NO YES Appendix A-1 to DG-4014, Page A-1-4 Discussion of Figure 3a. What does the DPR require me to do? Licensees should review existing plans and procedures related to identification and management of leaks, spills, aerosols, dispersible solids, and other unplanned releases. Licensees should pay particular
