1. 1 X UCOR Oak Ridge Sample Management Office 2015 Site Status Report Presented by Dr. William Rogers

2. UCOR Scope of Work on the Oak Ridge Reservation 2

3. UCOR Scope of Work Perform D&D and remediation activities across the Oak Ridge Reservation (ORR) Manage the ORR Landfill and the Environmental Management Waste Management Facility (EMWMF) Manage the Water Resource Recovery Program (WRRP) Manage the Liquid Gaseous Waste Operations (LGWO) facility Perform Environmental Compliance Monitoring Waste management and disposition Design of the Mercury Treatment Facility at Y-12 Construct new DOE Environmental Management Disposal Facility (EMDF) 3

4. D&D Activities at ETTP Current ETTP D&D Activities –K-27 (Entire Facility) –Poplar Creek Facilities –Multiple small facilities Planned Activities –Centrifuge Facilities –Central Neutralization Facility –Toxic Substances Control Act (TSCA) Incinerator –Balance of Facilities 4

5. w w w. e m. do e. go v 5 D&D Sampling and Analysis Analytical support for characterization of facility contents and construction debris K-25 slab and K-31 characterizations were completed in FY15 K-27 characterization is largely complete and transite removal has begun Poplar Creek High Risk Facility work has begun Other facilities are being shifted to UCOR scope as current projects are completed 8000 analyses performed in FY15 Total cost for analytical services ~$850K

6. Landfill Operations Environmental Management Waste Management Facility (EMWMF) –CERCLA waste associated with the ORR –Must meet WAC requirements Oak Ridge Reservation (ORR) Landfill – (formerly the Y-12 Sanitary Landfill) –Disposal of sanitary, industrial, construction, and demolition waste 6

7. w w w. e m. do e. go v 7 EMWMF and ORR Landfill Sampling and Analysis Sample Locations –Monitoring wells –Contact Water –Leachate –Air Sampling Number of analyses per year is relatively constant –Weekly, Quarterly, Semi-annual, Rainfall event driven (EMWMF) –Dynamic analytical suite for the EMWMF 6800 analyses performed in FY15 Total cost for analytical services $1M

8. Water Quality and Environmental Compliance 8

9. Water Quality and Environmental Compliance Sampling and Analysis 9 Samples –Groundwater –Surface Water –Outfalls –Runoff –Air Monitoring Annual sampling for Water Quality is relatively constant Environmental Compliance varies some, but overall is constant 15,000 analyses performed in FY15 Total cost for analytical services $1.1M

10. Waste Management and Disposition 10 UCOR has taken a proactive approach –characterize and ship as soon as practical The majority of legacy waste has been dispositioned 600 analyses performed on waste materials in FY15 Total cost for analytical services $60K

11. Site Remediation Expected increase in soil samples from the ETTP site Characterization is associated with land transfers and footprint reduction Will require very low reporting levels in some cases depending on final disposition of parcel FY14 ~$10K spent on remediation FY15 ~$55K spent on remediation FY16 projected to double 11

12. Bioassay and Industrial Hygiene Bioassay Program –600 analyses –$60K –FY 2016 is expected to remain constant Industrial Hygiene Program –3500 analyses –$250K –Expected to remain relatively constant through 2016 12

15. Analytical Support Summary Analytical laboratories performed over 39,000 analyses in support of UCOR projects in FY 2015. The total cost for analytical services in FY 2015 was ~$3.7M FY 2016 analytical support is expected to remain largely unchanged –New D&D characterization projects are expected to be added to the current scope as K-27 and Poplar Creek facilities near completion –Landfill, Water Quality, and Environmental Compliance Program needs are expected to remain constant –Analytical needs for waste characterization associated with the Waste Disposition Program are expected to decrease an additional 15-20% –Bioassay requirements are expected to stabilize at FY15 levels –Industrial Hygiene sampling is expected to remain constant 15
