1. U.S. Department of Energy Consolidated Audit Program (DOECAP) Labs and Treatment, Storage, and Disposal Facilities Kevin Cabble U.S. Department of Energy (DOE), Nevada Site Office (NSO) Analytical Services Program (ASP) – DOECAP Workshop September 19-23, 2011 / Pleasanton, California

2. Nevada National Security Site (NNSS) • U.S. DOE, National Nuclear Security Administration (NNSA) NSO responsible for oversight • Located 65 miles northwest of Las Vegas, NV • Approximately 1,360 sq. miles of federally owned and controlledland surrounded by 4,500 sq. miles of federally owned and controlled Nevada Test and Training Range (NTTR)

3. Historic Mission • From 1951 to 1992, the primary mission of the NNSS, formerly known as the Nevada Test Site, was to conduct nuclear and conventional explosives tests in connection with research and development of nuclear weapons • Environmental restoration activities began in 1989 to address environmental liabilities associated with nuclear weapons production and testing

4. Environmental Management (EM) • Characterization and clean-up activities at radioactive and non-radioactive contaminated sites (Environmental Restoration) • Activities focus on groundwater, soil, and on-site infrastructure contamination from historic nuclear testing • Radioactive andhazardous waste management and disposal • Environmental planning, compliance, and monitoring

5. NSO EM Prime Contractors • National Security Technologies, LLC (NSTec) • Remediation • Waste management • Non-EM work • Defense experimentation and Stockpile Stewardship • Homeland Security and defense applications • Navarro-Intera, LLC (N-I) • Corrective action investigations • Remediation • Groundwater modeling

6. Environmental Restoration (ER) • Comprised of three operations • Industrial Sites • Soils • Underground Test Area (UGTA) • Cleanup sites (referred to as Corrective Action Sites [CASs]) are grouped into Corrective Action Units (CAUs) based on contamination,location, and other technical characteristics • State of Nevada oversight provided under the Federal Facility Agreement and Consent Order (FFACO) K:\Public-Affairs\Public Affairs Common Web\Photos\54491 - CAU 484 Looking south - excavation, digging in south wall.jpg

7. Industrial Sites • Investigation, characterization, and remediation of 1,710 sites on the NNSS and NTTR (including the Tonopah Test Range [TTR]) at facilities used in support of nuclear testing • Remediation of contaminated sites includes leach fields, sumps, disposal wells, tanks, landfills, ordnance sites, and decontamination and decommissioning (D&D) of buildings • Contaminants of concern includes hazardous chemicals, unexploded ordnance, and low-level radionuclides K:\Public-Affairs\Public Affairs Common Web\Photos\56118 - CAU 117 Pluto Demolition 09-28-2010.jpg

8. Soils • Investigation, characterization, and corrective actions of 126 historic surface soil contamination sites • Atmospheric nuclear weapons tests • Nuclear safety experiments • Evaluation tests for peaceful uses of nuclear explosives (i.e., Plowshare Program) 41700.jpg = Soils CASs

9. UGTA PIRDy15-CRATER2.mpg • 828 underground nuclear tests conducted at the NNSS (1951-1992); one-third occurred near, below, or in the water table • Complex geology and hydrology of NNSS presents unusual challenges in understanding velocity, volume, direction of groundwater flow • Activities involve drilling, well sampling, characterization, and computer model development K:\Public-Affairs\Public Affairs Common Web\Photos\54336.jpg

10. FY 2011 ER Activities • Industrial Sites  • Completed demolition activities at CAU 116, Area 25 Test Cell C Facility • Completed Corrective Action Decision Document/Corrective Action Plan (CADD/CAP) for CAU 547, Miscellaneous Contaminated Waste Sites • Completed planning, remediation and Closure Report for CAU 566, Engine Maintenance, Assembly, and Disassembly (EMAD) Compound K:\Public-Affairs\Public Affairs Common Web\Photos\31689 CAU 566, EMAD Compound

11. FY 2011 ER Activities(continued) • Industrial Sites • Completed demolition activities at CAU 113, Reactor Maintenance, Assembly, and Disassembly (R-MAD) Facility • Conducted planning and demolition activities at CAU 117, Area 26 Pluto Disassembly Facility • Completed closure of CAU 539, Areas 25 and 26 Railroad Tracks K:\Public-Affairs\Public Affairs Common Web\Photos\54540.jpg R-MAD facility prior to (left) and after (right) demolition

12. FY 2011 ER Activities(continued) • Soils • Completed investigation and closure of seven CAUs • CAU 372, Area 20 Cabriolet and Palanquin Craters • CAU 106, Areas 5 and 11Frenchman Flat Atmospheric Sites • CAU 365, Baneberry Contamination Area • CAU 367, Area 10 Sedan, Ess, and Uncle Unit Craters • CAU 374, Area 20 Schooner Unit Crater • CAU 375, Area 30 Buggy Unit Craters • CAU 574, Neptune

13. FY 2011 ER Activities(continued) • UGTA • Groundwater characterization of wells drilled in FY 2010 • Data from new wells are used to support the NSO effort to study the complex geology and subsurface water systems of the NNSS • Objective is to provide a better understanding of the extent and future movement of radiological contamination in the groundwater so that Institutional controls and monitoring systems can be put in place to protect the public • Completion of the Corrective Action Investigation stage for CAU 98 Frenchman Flat

14. NNSS FY 2012 Planned ER Activities • Soils site investigations • Plutonium Valley unit dispersion sites • Yucca Flat atmospheric test sites • Hydronuclear sites • Industrial Sites • Close the miscellaneous contaminated waste sites • UGTA • Well testing, development, and monitoring • Groundwater modeling • Drilling
