Categorical Exclusion Determination
Office of NEPA Policy and Compliance
November 20, 2015In 2014, CH2M-WG Idaho, LLC (CWI) erected a temporary tension fabric structure at INTEC on the south side of building Chemical Processing Plant (CPP)-666. The structure was used by CWI as a temporary containment to facilitate replacement of the CPP-666 IX Column Resin (Davis Bacon Case Record No. Idaho Cleanup Project [ICP]-14-26). The Radiological Control organization from CWI has surveyed the tent and free released the equipment inside. The structure is no longer necessary for CWI and needs to be demolished or transferred to another entity. Battelle Energy Alliance, LLC (BEA) has identified a need for the structure at the Materials and Fuels Complex (MFC). Under the proposed action, CWI would transfer ownership to BEA, and BEA will disassemble the structure at INTEC, transfer the components to MFC, and re-erect the tension fabric structure. A 5-ton gantry crane, chain hoists, and other miscellaneous equipment would also be transferred from CWI and used within the tent. The tent is equipped with ceiling lights, floor stand heaters, and a manual chain drive roll-up door. Power would need to be supplied to the tent after erection, and this EC will be revised to capture the scope, aspects, and work activities associated with supplying power to the facility. Balance of plant equipment and supplies (including sanding trucks, supplies, and sweeper attachments) would be stored in the facility at MFC. Empty casks could be parked in the structure when they are not in use. Changes to this scope will require revision of this EC.
