PENNSYLVANIA’S ENVIRONMENTAL MONITORING PROGRAM AROUND NUCLEAR FACILITIES

1. PENNSYLVANIA’S ENVIRONMENTAL MONITORING PROGRAM AROUND NUCLEAR FACILITIES Tonda Lewis

2. Radiation Protection Act (1984-147) • Maintain comprehensive environmental radiation monitoring program around nuclear power plants and other locations throughout the Commonwealth • Accomplish efficiently and effectively

3. DEPARTMENT OF ENVIRONMENTAL PROTECTION BUREAU OF RADIATION PROTECTION Environmental Surveillance Section

4. Environmental Monitoring Program Includes • Split and independent sampling around PA’s five nuclear power plants • Sampling at decommissioning sites • Background Sampling – non-source oriented

5. PA’s Nuclear Power Plants • Beaver Valley Power Station • Limerick Generating Station • Peach Bottom Atomic Power Station • Susquehanna Steam Electric Station • Three Mile Island Nuclear Station

7. Within 15 mile radius of each facility • 30 – 36 environmental dosimeters • Majority within 5 miles • Changed quarterly • Many collocated with the facilities’ • Currently still operate our own system but doing comparison study with a service

8. Within 5 miles of each facility • 4 air sampler units – several collocated with each utility’s • Continuously collecting air particulates and radioiodines • Filters are analyzed weekly for gross activity and composited quarterly for gamma spec analysis • Charcoal canisters are analyzed weekly by gamma spec for I-131

9. Water Sampling Upstream & Downstream of Discharge • 2 – 3 Water samples • One is upstream control • Monthly composites collected by utility’s contractor and split with state • Gross beta, H-3, gamma Holtwood Dam – Peach Bottom sample source

10. Milk Collected At Area Farms • 2 Farms sampled monthly • One farm is chosen for nearest proximity in most prevalent wind direction • One farm chosen for least prevalent wind direction • Samples are all collocated with utility’s collections • Contractor splits with Peach Bottom, Susquehanna and Limerick

11. Flora, Fauna and Sediment • Vegetation annually Leafy - for deposition Root crop - irrigation • Fish - annual or biannual contractor split collections • Sediment below discharge annually or biannual contractor split collections

12. Beaver Valley Monitoring Sites Fish TLDs Vegetation Sediment Milk Air

13. Alpha Beta Proportional Counters (3 Autoquads 1 Single) 2 Liquid Scintillation Counters 8 Ludlum Scaler Alpha detectors 2 Quad Alpha Beta Proportional Counters 1 Uranium Analyzer U-A3 12 Alpha Spec detectors 10 Intrinsic Germanium detectors 1 XRF Spectrace 5000 for metal analysis Sample Analysis -State’s Radiation Measurements Laboratory Analytical Equipment

14. What Do We Do With Results • Results are reviewed upon receipt • When anomalies are detected, utilities are contacted • At the end of the year (sometimes quarterly) data is exchanged with utility • Bureau publishes our own data in annual report • Our data must be available to the public

16. Environmental Tlds

17. Exchange of Utility and State Water Analysis Results Uti

18. Routine sampling around remediation sites • Molycorp ( produced ferro-columbian alloy concentrating thorium): air sampler and tlds • Quehanna (home to variety of research & manufacturing-reactor, SNAP generators using sr-90, currently co-60 irradiation of wood products): 5 air samplers and tlds • Waltz Mills (Westinghouse site, home of failed 1960 test reactor): 2 air samplers

19. Assist with Non- routine sampling at other projects • Safety Light in Bloomsburg PA • Babcock & Wilcox in Parks Township PA • Molycorp in York PA

20. Background Monitoring • PMN: PA Milk Network Processed milk - 4 cities • Water Quality Network Surface water from 11 sites • Philadelphia Drinking Water – 3 treatment plants • Harrisburg Precipitation • Rooftop Air monitor
