1. Annual Site Environmental Report (ASER)Calendar Year 2011 Presented by: John Rendall, Regulatory Strategy Manager November 14, 2012 West Valley Demonstration Project

2. Information in the ASER • Background Information • Environmental Compliance Summary • Review of Regulatory Programs • Accomplishments • Environmental Management System (EMS) Information • Environmental Monitoring • Monitoring Program • Groundwater Protection Program • Dose Assessment • Appendices • Environmental Monitoring Data Tables • Other Useful Information • Definitions 2

3. Environmental Compliance Zero Regulatory Notice of Violations • EPA RCRA Inspection • Regular NYSDEC Site Visits • Cattaraugus County Health Department Monthly Potable Water Sample Collection • NYSDEC SPDES Inspection • NYSDEC RCRA Inspection One SPDES permit limit exceedance last Fall (October 2011) • Mercury Limit (346 ng/l vs 200 ng/l standard) • Reported at previous QPM/CTF Meetings 3

4. EMS Registration Received 4

5. EMS – Implementation of Environmental Policy • Comply with environmental requirements • Minimize generation of wastes without path for disposition • Protect and conserve WVDP natural resources • Establish environmental targets and objectives • Regulatory Closures (RCRA, SPDES, NESHAPs) • Conservation (e.g., “green” purchases, energy usage reductions) • Consider Stakeholder Input (e.g., CTF, QPM participation) • Monitor potential environmental impacts • Commitment to continuous EMS improvement • Communicate Environmental Policy • EMS performance verified through independent third party audits 5

6. Environmental Monitoring • Environmental monitoring data summarized in Annual Site Environmental Report (ASER) • Approximately 8,000 Samples/Year collected from over 200 locations • Surface water, air, sediment, soil, food/biota (e.g., fish, deer, milk), onsite drinking water • Ensures worker and public safety • Uploaded to DOE website October 2012 (for Calendar Year 2011) DOE WVDP internet site: http://www.wv.doe.gov/ • Radiological and non-radiological analytical scope documented in ASER Appendix A • Total effective dose equivalency (EDE) from waterborne and air pathways (2011 ASER): Maximum Exposed Off-Site Individual (MEOSI) 0.044 mrem (0.044% of DOE 100 mrem Standard) 6

8. Environmental Monitoring Monitoring Types • Air: Stack monitoring and ambient air (Great Valley background sample) • Groundwater (208 onsite routine groundwater monitoring locations) • Surface Water: onsite (e.g., Franks Creek, Erdman Brook) and offsite sampling points (e.g., Buttermilk Creek, Cattaraugus Creek) • Sediment and Soil: Onsite and offsite samples • Food/Biota (e.g., fish, deer, milk) • Onsite Drinking Water (monthly Drinking Water Report) • Radiological and non-radiological analytical scope documented in ASER Appendix A No Issues Identified from environmental surveillance samples 8

9. Environmental Monitoring Liquid Effluent Site Sewage Treatment Plant (STP) Non-radiological discharge Primarily discharges Mon - Thu Low-Level Waste Treatment Facility (from Lagoon 3) Batch discharges (~ six discharges/year) Monthly reporting to NYSDEC Stormwater Discharges 19 Stormwater discharge outfalls Site Drainage Points Natural drainage from northeast swamp Upgradient Permeable Treatment Wall installed in 2010 Plant Ventilation Stacks 7 Stacks and up to 15 portable ventilation units Extremely low emissions (less than 0.02% of standard) 0.0017 mrem/yrvs 10 mrem/yr standard (for Maximum Exposed Offsite Individual, MEOSI) RHWF Stack Monitoring System 9

10. Ambient Air Monitoring Program Presented by: John Rendall, Regulatory Strategy Manager November 14, 2012 West Valley Demonstration Project

11. Ambient Air Monitoring Update Ambient air network operating • Monitoring program initiated October 1, 2012 Background and 16 stations on NYSERDA and private properties • Small units (2’x3’x7’) • Located approximately 1 mile or less from site Objective of Ambient Monitoring Program • Monitor diffuse source emissions • Collect ambient air data in proximity to nearest receptors • Augment existing monitor and model approach 11

12. Ambient Monitoring Program Monitoring Program • Biweekly gross alpha and beta • Quarterly isotopic for key WVDP isotopes • Glass fiber filters – typical particle retention – 99.98% • Charcoal cartridge for I-129 • Minimum of 80% continuous monitoring • Continue meteorological monitoring and monitor and model of emissions • Compare ambient to monitor and model approach 12
