Closure Plan for the E-Area Low-Level Waste Facility
To comply with the applicable requirements of the U.S. Department of Energy (US DOE), this closure plan has been developed for the E-Area Low-Level Waste Facility(LLWF). The plan is organized according to the specifications of the Format and Content Guide for U.S. Department of Energy Low-Level Waste Disposal Facility Closure Plans. Section 2 provides a brief overview of the general facility description, closure approach, closure schedule, related activities, and key assumptions. Sections 3 and 4 provide specific details of facility characteristics and the technical approach to closure, respectively, as well as supporting information. Additional schedule details are provided in Section 5. Section 6 provides a list of recommended items for consideration in association with future revisions to the E-Area LLWF Closure Plan and Performance Assessment (PA). Operation of the E-Area LLWF began with placement of the first low-level waste box within the Low Activity Waste (LAW) Vault. It is anticipated that operations will continue for at least 25 years, and that a 100-year institutional control period will follow cessation of operations. It is further anticipated that closure will be conducted in the following three phases: operational closure, interim closure, and final closure. Operational closure will be conducted during the 25 year operational period as disposal units are filled, is specific to each type of disposal unit, and it is primarily intended to minimize infiltration, facilitate operations, promote worker safety, and prepare the facility for interim closure. Interim closure will be conducted after disposal operations have ceased, it is specific to each type of disposal unit, and it is primarily intended to minimize infiltration during the 100-year institutional control period and prepare the facility for final closure. Final closure of the entire E-Area LLWF will occur at the end of the 100-year institutional control period. Final closure will consist of site preparation and construction of an integrated closure system composed of one or more closure caps installed over all the disposal units and a drainage system. The final closure will thus be essentially the same for each disposal unit. Final closure is primarily intended to minimize infiltration during the post institutional control period and provide an intruder deterrent.
