LLW Policy & Goals DOE Order 435.1 defines policy and allows DOE sites to use on-site and off-site disposal paths, as well as commercial treatment and disposal facilities. DOE closely monitors potential changes in the commercial market – treatment and disposal waste volumes are considerably lower since legacy wastes are largely gone. Low-level Waste Disposal Facility Federal Review group (LFRG) Goals: Confirm that the disposal of LLW at DOE facilities is conducted in a manner that is protective of public health and safety and the environment, by providing regulatory oversight. Ensure consistency in approach and application with the design, construction, operation, and closure of LLW disposal facilities. Ensure compliance with DOE 435.1 requirements.  

Waste Highlights In February 2017, the Idaho site marked the completion of a 15-year effort to retrieve 65,000 cubic meters of TRU waste at the Advanced Mixed Waste Treatment Project for eventual off-site shipment. Los Alamos National Laboratory have completed two-thirds of treatment of the remediated nitrate salt drums. The estimated completion date for treatment is November 2017.  In July 2017, workers completed the construction of the 33-million gallon Saltstone Disposal Unit 6 at Savannah River Site. In September 2017, demolition began on the vitrification facility at West Valley Demonstration Project.

Complex-wide LLW/MLLW Disposal Rates by Disposal Location

Status on GTCC LLRW & GTCC-Like Waste Disposal In February 2016, DOE published the Final Environmental Impact Statement for the Disposal of Greater-Than-Class C (GTCC) Low-Level Radioactive Waste and GTCC-Like Waste GTCC LLW has radionuclide concentrations that exceed the limits for Class C LLW. GTCC LLW currently does not have a defined disposal path. GTCC-like waste is DOE owned or generated LLW or TRU waste with characteristics similar to GTCC LLW, and with no identified disposal path. Preferred alternative: land disposal at generic commercial facilities and/or WIPP geologic repository. The Final EIS has the potential to enable disposal of the entire GTCC LLW and GTCC-like waste inventory of approximately 12,000 cubic meters (m3). Presently there is no preference among the three land disposal technologies (intermediate- depth borehole, enhanced near-surface trench, and above-grade vault) at generic commercial facilities. In accordance with the Energy Policy Act of 2005, before the Secretary of Energy makes a final decision on the disposal alternative(s) to be implemented, a Report to Congress must be submitted. The Report to Congress has been drafted and is in concurrence.

Status on GTCC LLW & GTCC-Like Waste Disposal Cont. Issue Record of Decision Await Congressional Action Submit Report to Congress The Report to Congress will: Describe alternatives under consideration Identify waste volume, concentration, and other relevant characteristics Identify the Federal and non-Federal options for disposal Describe actions to ensure safe disposal of identified radioactive wastes Describe projected costs Identify options for ensuring that the beneficiaries of the activities resulting from the generation of GTCC LLW bear all reasonable costs of disposing of such wastes Identify statutory authority required for disposal of GTCC LLW

Overview of Waste Disposition Activities Spring 2017 LLW Forum Meeting Update on TRU Waste Shipments to WIPP WIPP shipments resumed in April 2017 Overview of Waste Disposition Activities Spring 2017 LLW Forum Meeting Doug Tonkay Director of Waste Disposal Office of Environmental Management April 25, 2017

Update on TRU Waste Shipments to WIPP cont. Current emplacement rates support 3-4 shipments per week. Emplacement and shipping rates will increase progressively with operational experience, lessened contamination, and equipment upgrades. Panel 7 expected to take 3-4 years to fill. Significant efficiencies are expected with new ventilation system and movement into Panel 8.

Update on TRU Waste Shipments to WIPP cont. Sites currently shipping (shipments received through 9/20/17): Idaho National Laboratory (40) Savannah River Site (9) Waste Control Specialists (11) Oak Ridge National Laboratory (3) Los Alamos National Laboratory expected to ship later this year. Sites estimated to ship in the next few years: Argonne National Laboratory Lawrence Livermore National Laboratory Sandia National Laboratory
