5. UMTRA Title I and Title II Disposal and Processing Sites • There are 36 Uranium Mill Tailings Radiation Control Act (UMTRCA) Title I and Title II processing or disposal sites managed LM. • Twenty-two inactive uranium ore-processing sites were remediated resulting in the creation of 19 disposal cells. • Active ground water remediation is ongoing at Monument Valley, AZ, Shiprock, NM, and Tuba City, AZ.

6. UMTRA Current and Anticipated Sites

7. Riverton, Wyoming, Processing Site • The groundwater compliance strategy for the Riverton site is natural flushing in conjunction with institutional controls and monitoring. • Groundwater modeling conducted in the 1990s predicted that site-related molybdenumand uranium in the surficial aquifer would flush naturally to levels below their maximum concentration limits within the 100-year time frame allowed in 40 CFR 192.

8. Riverton, Wyoming, Processing Site In June 2010, record flows caused the Little Wind River to overflow and flood a large area downgradient of the former mill site. Groundwater sampling conducted two weeks after the flood showed significant increases in contaminant concentrations in nearby monitoring wells.

9. Riverton, Wyoming, Processing Site • The 2010 flood of the Little Wind River demonstrated a direct correlation between high discharge in the Little Wind River and increased contaminant concentrations in the surficial aquifer. • An enhanced characterization of the surficial aquifer was conducted in 2012, which included installation of 103 boreholes along 9 transects, collection of 103 water samples and 65 soil samples, laboratory tests on the soil samples, and additional groundwater modeling.

10. FUSRAP Sites • There are 29 Formerly Utilized Sites Remedial Action Program (FUSRAP) managed by LM. • These are sites where radioactive contamination remained from Manhattan Project and early U.S. Atomic Energy Commission (AEC) operations • When required, remediation is performed either by the DOE or the U.S. Army Corps of Engineers. • FUSRAP sites transfer to LM for long-term care once remediation is completed

11. CERCLA/RCRASites • There are 8 sites managed LM where remediation was conducted in accordance with Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and/or Resource Conservation and Recovery Act (RCRA) regulations. • These sites were radiologically and/or chemically contaminated by federal milling, processing, research, and/or weapons manufacturing operations.

12. CERCLA/RCRA sites account for about 70% of the samples per year collected for LM. CERCLA/RCRASamples

13. CERCLA/RCRAMonitoring • Fernald – • Groundwater treatment system • On-site disposal facility • NPDES • Groundwater • Surface water • Pinellas – • Groundwater • Monticello – • Groundwater treatment system • Groundwater • Surface water • Rocky Flats – • Four groundwater treatment systems • Groundwater • Surface water • Mound – • NPDES • Groundwater • Surface water • Weldon Spring – • Groundwater • Surface water

14. Nevada OffsitesSites • There are 9 sites where underground nuclear tests and experiments were performed outside of the Nevada Test Site (Nevada Offsites). • Long-term monitoring activities consist primarily of ensuring that use restrictions remain in force and maintaining site integrity to protect public health and the environment.

15. DOE Defense Decontamination and Decommissioning (D&D) Program Sites • The D&D Program was responsible for the surveillance and maintenance of surplus DOE facilities, including any decontamination and decommissioning activities. • With the exception of the Grand Junction Site, these are decommissioned reactor sites.

16. Legacy Management Sites Current Sites There are 91 site managed by LM. There are 44 sites that have analytical support requirements. There are 40 sites identified for transfer to Legacy Management over the next 10 years.

17. Number of Samples per Year

18. Analytical Services Contracts • Analytical services were procured utilizing the ICPT Basic Ordering Agreement along with an LM-specific requirements document. • Contracts with GEL Laboratories, ALS Laboratory Group, and TestAmerica were awarded March 2008. • The total dollar amount of the contracts for FY2012 was 859K. FY2013 estimated total is 770K. • Other contracts for special analytical services and site-specific requirements are established as needed.

19. DOECAP Participation Legacy Management has three DOECAP auditors, one lead auditor. • Quality Assurance Management Systems and General Laboratory Practices • Data Quality for Organic Analyses • Data Quality for Inorganic and Wet Chemistry Analyses • Data Quality for Radiochemistry Analyses • Laboratory Information Management Systems/Electronic Data Deliverables • Hazardous and Radioactive Materials Management

20. Legacy Management Status Summary • The number of samples is averaging 7000 samples per year. • Additional sampling may be needed at select UMTRA sites to support enhanced site characterization. • Legacy Management will rely on DOECAP as the primary provider of laboratory audits.
