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 EMS – Implementation of Environmental Policy 5

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: 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) mrem (0.044% of DOE 100 mrem Standard) 6

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

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 Ambient Air Monitoring Update 11

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 Ambient Monitoring Program 12
