1. The NEW Federal Waste Facility – WCSSeptember 24, 2013

2. WCS Safety and Quality Focus • WCS maintains strong, overarching commitment to safety and quality • WCS worked over 6 years without a lost time accident. Including over 1.6 million safe work hours. • WCS promotes a safety culture consistent with best nuclear utilities: • Trust-based organization • Open communication free from concerns over reprisal • All workers have right and obligation to report safety and quality concerns • Management practices conservative decision-making

3. WCS Services WCS provides the most comprehensive, full service, and complete Radioactive and Hazardous Waste Services in the Nation. Disposal • Low-level radioactive waste (LLRW)/Mixed LLRW (MLLRW) • RCRA/TSCA Regulated Waste (Hazardous waste) • Texas Exempt Waste • Byproduct Material Storage • Radioactive Waste, incl. GTCC LLRW, Transuranic Waste, Sealed Sources, and Byproduct Material • RCRA/TSCA Waste Treatment/Processing • Mixed LLRW (MLLW) • RCRA/TSCA Waste • TRU • Exemption to treat and store Special Nuclear Material (SNM) below certain concentration limits based on criticality – U.S. NRC in November 2001

5. License Status

6. Radioactive Waste Disposal License • LLRW and Mixed LLRW Disposal • Final LLRW license received ─ September 2009 • CWF - First LLW disposed ─ April 2012 • FWF – Ready for operations – September 2012 • Disposed of first FWF waste shipment – June 6, 2013 • FWF also has RCRA Permit and TSCA/CERCLA authorizations • Includes Federal and Compact Landfills • DOE signed Agreement to take ownership of the Federal Landfill after post-closure • TCEQ has taken ownership of Texas Compact Landfill and WCS leases it back for operations

7. Federal Waste Facility Disposal Facility Basics (cont’d) • FWF Disposal Capacity - 26,000,000 cubic feet • Accepts Class A, B, and C Low-Level Radioactive waste for disposal (as defined in both 10 CFR 61.55 and 30 TAC 336.362 Tables 1 & 2) • Accepts Class A, B, and C Mixed LDR-compliant waste for disposal (excludes F020, F021, F022, F023, F026 and F027; Dioxins & Furans) • Up to 100 nCi/g transuranic isotopes • Disposal is just one aspect of WCS’ comprehensive waste services, including storage, treatment, and processing 7

8. Current Capabilities • Special Nuclear Materials • –Allow WCS to take possession of USDOT limits of SNM on a conveyance prior to disposal • Co-disposal Concept • – Allow for WCS to dispose of Class A soil/debris waste and large components outside of an MCC, with limited size restriction. • Receipt by Rail • Containerized LLW and MLLW acceptable • Irradiated Hardware Transfers • Typically 10,000 to 30,000 Rem/hr. • Resin Dewatering

9. Upcoming Capabilities • Type B Cask Services • Expected in Late Fall 2013 • Depleted Uranium Disposal • Submitted a major amendment to revise the performance assessment to take ~400,000 m3 of DU (large quantities) as well as other LLW near the Class C limits. Amendment is expected to be approved May 2014. • Facility Clearance • Other Capabilities • As needed by customers

10. WCS Design

11. WCS Compact Landfill – Native Clay Compact Disposal Facility
