1. DOE Office of Environmental Management – Oak Ridge Office • ASP 2011 Workshop • September 19 – 23, 2011 • Pleasanton, California • Presented by: Peggy Wilson, DOE ORO EM

2. PRESENTATION TOPICS • Oak Ridge Reservation • ORO EM Mission Focus • EM Rank Order Priorities • Historical Cleanup Challenge • ETTP 20 Years of Progress • ORNL 20 Years of Progress • Y-12 20 Years of Progress • Commercial Laboratories Usage • Treatment Storage and Disposal Facilities Usage • American Recovery and Reinvestment Act (ARRA) • Challenges of Today • Looking to the Future

3. Oak Ridge Reservation Y-12 Three Sites with Unique Legacies Oak Ridge’s missions and capabilities are vital for our nation.

4. Mission Focus D & D Completed Resolving the legacy of the nuclear weapons program and making the site available for future use: • Complete Transformation of ETTP as part of Oak Ridge Energy Corridor • Complete TRU Waste Processing • Resolve U-233 Inventory Enabling vital DOE missions and protecting national assets: • Address legacy facilities and contamination in midst of new facilities and ongoing missions

5. EM Mission and Rank Order Priorities Safe, secure, and compliant posture High-level waste disposition Spent nuclear fuel storage and disposition Special nuclear material consolidation, processing, and disposition High priority groundwater remediation Transuranic and mixed/low-level waste disposition Soil and groundwater remediation Excess facilities deactivation and decommissioning (D&D) “Complete the safe cleanup of the environmental legacy brought about from five decades of nuclear weapons development, production, and Government-sponsored nuclear energy research.”

6. The Formidable Cleanup Challenge (Circa 1990) • Threats of off-site surface water and • groundwater contamination • Close proximity between Reservation and City of Oak Ridge Experimental reactors Weapon component production facilities Massive inventory of legacy waste and excess materials Hundreds of contaminated facilities Numerous burial grounds

7. Seepage pond waste 5M gal sludge - DISPOSED Legacy materials 7000 DUF6 cylinders - REMOVED Contaminated media 35,000 cubic yards - DISPOSED Gaseous Diffusion Buildings (D&D) 5 Buildings with 100 acres of footprint K29 -- DISPOSED K31/K-33 -- DEACTIVED K25 and 27 -- UNDERWAY 250 other facilities - DISPOSED TSCA Incinerator (1991-2010) 35M pounds waste - DISPOSED RCRA closure - UNDERWAY ETTP: Twenty Years of Progress

8. Aging underground waste tanks 42 LLW tanks -- REMEDIATED 8 Gunite Tanks -- REMEDIATED Shallow land burial grounds 140 acres – CAPPED Offsite releases – MITIGATED Corehole 8 groundwater plume treatment system TRU Waste Processing Center 429,000 gal supernatant – PROCESSED >400cy Con-Han debris – PROCESSED >27cy Rem-Han debris – PROCESSED ORNL: Twenty Years of Progress

9. Mercury releases -- MITIGATED Big Spring Water Treatment System Burial grounds -- REMEDIATED 65,000 cy waste and soil removed Facility D&D Alpha 4 deactivation - COMPLETE Alpha 5 cleanout - COMPLETE Biology Complex – UNDERWAY CERCLA disposal cells Fifth expansion cell – OPERATIONAL Sixth expansion cell – UNDERWAY Y-12: Twenty Years of Progress –

10. The Enabled Future State TRANSFORMED MODERNIZED REINDUSTRIALIZED

11. Commercial laboratories • ORO-EM currently contracts with the following laboratories • ALS Paragon – Ft. Collins, CO • Eberline - Oak Ridge, TN • GEL-South Carolina • Lionville Laboratory Inc. – Lionville, PA • Test America – Knoxville, TN • Test America – St. Louis, MO • Southwest Research – San Antonio, TX • Cebam- Washington State • Materials & Chemistry Lab - Oak Ridge, TN • RMAL- Oak Ridge, TN • BWXT Services – Lynchburg, VA • Y-12 (Analytical Chemistry Organization) – Oak Ridge, TN

12. Total dollar amounts awarded for analytical work under the oak ridge sample management office • FY 2010 $10.5 million with 97% going to commercial laboratories • FY 2011 $7.5 million through July business month with 98% going to commercial laboratories • Future Analytical Needs • FY 2011 to remain steady (includes ARRA work) • Slight decrease FY 2012

13. Special analytical needs • Unusual matrices (Brine analysis) • Mercury • Hi Level Rad Samples • No-Rad Added Determination

14. Treatment Storage and Disposal Facilities (TSDF’s) • ORO-EM currently contracts with the following TSDF’s • Diversified Scientific Services, Inc. (PermaFix) – Kingston, TN • Energy Solutions – Clive, Utah • Energy Solutions –Kingston, TN • PermaFix-Gainesville, FL • PermaFix-Richland, WA • Materials and Energy Corporation – Kingston, TN • Clean Harbor

15. Total dollar amounts awarded for waste storage and disposal • FY 2011 projected $15 million going to contracted Treatment Storage and Disposal Facilities

16. ARRA Success -- Essential Elements • Comprehensive advanced planning • Approved CD-1 package for reservation-wide clean-up scope • Front-end facility characterization and surveys • Waste acceptance criteria for debris disposal • Capitalized on local assets • Trained and experienced work force • Vibrant subcontracting community • Use of specialty small businesses • Improved project management • Established manageable projects (discrete and well defined) • Projects fully funded • Appropriate contingency values assigned

17. High potential – high volume contaminant releases could impact co-located personnel and ongoing missions National Lab priorities, new facilities and third-party ventures are at risk Offsite ground water impacts Devalues and discourages investments in modernization and new missions Impeding large-scale growth of future commercialization and reindustrialization Legacy Facilities Threaten Vital Missions and Modernization • Our clean-up work is not done!

18. Looking to the Future: Building on Success Collaborative approach between EM, NNSA and Science Outstanding Safety Record Close engagement with our Regulators High return on clean-up investments Efficient and experienced workforce

19. At ORO, we are excited about the next decade in Oak Ridge
