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. TLDs Sediment Vegetation Milk Air Fish Beaver Valley Monitoring Sites

13. Sample Analysis - State’s Radiation Measurements Laboratory Analytical Equipment 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

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
