3. www.energy.gov/EM 3 Regulatory Framework  DOE Radiological Regulatory Authority Authority under Atomic Energy Act DOE Order 435.1 Change 1, Radioactive Waste Management Low-Level Radioactive Wastes (LLW) and Transuranic (TRU) Wastes  New Mexico Environment Department Authority Hazardous waste regulations implement EPA Resource Conservation and recovery Act (RCRA) requirements Hazardous Waste Facility Permit addressing treatment, storage, and disposal of hazardous wastes  Waste Disposal LLW disposal operations in Area-G is under DOE authority under the National Nuclear Security Administration (NNSA) TRU wastes in Area G include newly-generated TRU from NNSA operating facilities and Legacy TRU (EM responsibility) DOE authority over TRU handling, processing, shipment, and disposal NMED authority over treatment, storage, and disposal of hazardous materials under permits

4. www.energy.gov/EM 4 Facilities  3 Hazard Category II Nuclear Facilities  TA-54 Area G – used for storage, certification, venting, and processing  TA-54 Radioassay and Nondestructive Testing (RANT) – used for staging and shipping  TA-50 Waste Characterization Reduction and Repackaging Facility (WCRRF) – used for drum repackaging

5. www.energy.gov/EM 5 TA 54 Area G  63 Acre Site  10 Large Storage Domes  Central Characterization Project (CCP), Assay, Real-Time Radiography (RTR), Gas Analysis, In-Situ Object Counting System (ISOCS)  Drum Venting  3 Repackaging Lines (412, 375, 231)

6. www.energy.gov/EM 6 TA-54 RANT  10,000 square foot facility  TRUPACT II Loading Facility  Second 5 Ton Crane Added in 2013 to eliminate single point failure  Capability for average of 5 shipments a week, with surge to 12  Department of Transportation (DOT) compliant shipping using DOE's national treatment and disposal contracts

7. www.energy.gov/EM 7 TA-50 WCRRF  Hazard Category II Nuclear Facility  Operation consists of outside transportainer storage and one operating glovebox  Facility maintains cascading ventilation though two ventilation systems  High Material at Risk (MAR) Drums
