3 Executive Summary EXECUTIVE SUMMARY The North Carolina Radiation Protection Section (NCNCRPS) conducts a radiological environmental surveillance program in the surrounding environment of major nuclear facilities and the statewide environment. From 1986 through 2009, NCNCRPS has monitored the offsite environment around the facilities listed below. Previously this monitoring was performed under a contract with the U.S. Nuclear Regulatory Commission (NRC), until that program was terminated by the NRC for budgetary reasons in During the 2009 calendar year, the NCNCRPS environmental monitoring program continued at Progress Energy s Brunswick Nuclear Plant (BNP), Shearon Harris Nuclear Plant (HNP), Duke Energy s McGuire Nuclear Station (MNS) and Global Nuclear Fuels Uranium Fuel Fabrication Plant (GE) in Castle Hayne. Cooperation between the NCNCRPS and the nuclear facilities continued during An overview for each plant is discussed in the individual plant summaries. Statewide environmental monitoring results, results of monitoring around other facilities, and a series of technical appendices are included in this report. These appendices list applicable minimum detectable activity (MDA) values for the program and sample analysis procedures at the N.C. State Laboratory for Public Health. No significant amounts of man-made radionuclides were discovered in samples collected by NCNCRPS in For a brief summary of sample analysis results and trends for the major components of the NCNCRPS environmental surveillance program please see the section below.

4 Executive Summary Brunswick: No man-made radionuclides found in air, surface water, ground water, terrestrial vegetation, food crop, sediment, or fish samples collected in No appreciable trend increase in man-made radionuclides in Brunswick samples from 2008 to McGuire: No man-made radionuclides found in air, surface water, milk, sediment, or food crop samples collected in Small amounts of fission products (Cs-137) found in fish at location MG-FL-129. Slight trend decrease in man-made radionuclides in McGuire samples from 2008 to Statewide: No man-made radionuclides in air, surface water, finished water, shellfish, precipitation, milk samples collected at statewide sites in No appreciable trend increase in man-made radionuclides in statewide samples from 2008 to Trace amounts of Iodine-131 found in twenty out of thirty six sewage effluent samples collected in This can be compared to 2008, when seventeen out of thirty four sewage effluent samples tested positive for trace amounts of I-131. These detections of I-131 are attributable to medical patient waste entering the sewage effluent stream, and do not represent a significant risk to public health. The overall NCRPS monitoring program continues to be adjusted in light of state funding restrictions. In 2009, the environmental monitoring programs at the PCS Phosphate and the B-52 Crash Site in Faro, NC were placed on hiatus due to NCRPS staff reductions and budgetary concerns. In the face of these staffing and funding issues, NCRPS management made the decision to concentrate future monitoring efforts on fixed nuclear facilities. It is hoped that if funding and staffing return to pre-2009 levels, monitoring at these facilities can resume in the future. Finally, NCRPS revised its ambient gamma monitoring program in The thermoluminescent dosimeters (TLDs) used to monitor for ambient gamma radioactivity were replaced with optically stimulated luminescent dosimeters provided under contract by Landauer, Inc. The ambient gamma sampling frequency was also reduced from a quarterly to an annual basis. Appendices Appendix A lists the regulatory limits, investigation levels, average NC background levels, and estimated lower limits of detection for the State Radiochemistry Laboratory. Appendix B lists the basic procedures for radiological analysis used by the State Radiochemistry Laboratory in analyzing environmental samples for nuclear facilities, statewide monitoring, and special projects. Appendix C lists the requirements for monitoring around the nuclear power plants and the Global Nuclear Fuels Facility. ACKNOWLEDGEMENTS and ATTRIBUTION: The NCRPS recognized contributions made by the various county city and other public agencies who assist in sample collection. Others giving their assistance in the collection of samples 1-2

5 Executive Summary include Progress Energy, Duke Energy, and PCS Phosphate. With the exception of thermoluminescent dosimetry, all other samples were prepared and analyzed by the following staff members of the State Public Health Radiochemistry Laboratory: Roger Brown (Supervisor), Brenda Nichols, Brenda Beasley, Zhong Zhang, and Teresa Bryant. Sample collection and report compilation were performed by the following Radiation Protection staff: Patrick Cox (Brunswick & GNF), William Jeffries (Statewide), and Chris Fidalgo (Harris, McGuire, Catawba, and PCS). NOTES ON RADIATION TERMINOLOGY: Throughout the Environmental Radiation Surveillance Report, several basic distinctions regarding radioactive isotopes (alternatively termed radionuclides) have been made. Natural vs. Man-Made: Simply put, the terms natural and man-made radioactivity mean just that: Natural radioactivity arises from processes of natural origin, such as the decay of Naturally Occurring Radioactive Materials. Man-made radioactivity originates from processes associated with human activity, such as nuclear power generation, nuclear fuel enrichment, research, medical procedures, etc. Man-Made Radioactivity: For the purposes of this report, several broad categories of manmade radioactivity can be defined as the following: Fission Products: Radionuclides generated from the process of nuclear fission; i.e., splitting the atom. The detection of nuclear fission products indicates the occurrence of fission-related activities, primarily as a result of nuclear power generation or nuclear weapons testing. Activation Products: Radionuclides generated from neutron activation, i.e., the bombardment of atomic nuclei with neutrons. Activation products are typically generated as a secondary process in nuclear power generation, research activities, or nuclear weapons testing. Enriched Uranium: Uranium is a naturally occurring radioactive material. However, if the ratios of uranium isotopes detected in a given sample are different than that occurring in natural uranium, the uranium is considered to be enriched. Enriched uranium is commonly encountered at nuclear fuel production/fabrication facilities, such as Global Nuclear Fuels. 1-3

6 BRUNSWICK STEAM ELECTRIC PLANT

7 BSEP - Summary BRUNSWICK STEAM ELECTRIC PLANT SOUTHPORT, BRUNSWICK COUNTY Progress Energy operates the Brunswick Steam Electric Plant (BSEP) located approximately 2.5 miles north of Southport, North Carolina. The plant consists of two boiling water reactors each with a net design rating of 821 Megawatts-electric and uses the Cape Fear River as its source for condenser cooling water. Commercial production was initiated by Unit 2 on November 3, 1975, and by Unit 1 on March 18, Air Particulate - Gross Beta The average gross beta concentration measured in 520 air particulate samples collected during the 2009 environmental surveillance year was 1.87 E-2 picocuries per cubic meter (pci/m 3. The analyses of the NCRPS air particulate samples collected show gross beta activity levels, which are within the levels of indicative of normal background and do not indicate any unusual activity. Air Particulate Gamma Analyses Gamma isotopic composite results identified only naturally occurring radioactive material, commonly referred to as NORM, at or below normal background levels. Air Particulate Air Radioiodine All air canisters analyzed for Iodine 131 (I-131) were found to have results below the lowest level detectable (LLD). Surface Water Gross Alpha/Beta, Tritium, Low Level Iodine & Gamma Analyses Results for the monthly surface water composites collected during 2009 show that Tritium (H-3) levels are below the investigation level of 1000 pci/l (See Appendix A). Naturally occurring Potassium 40 (K-40) was evident in samples collected. The highest levels detected were less than 700 pci/l for both the indicator and control sites. Low level iodine (LLI) was only identified in the indicator sites samples at trace levels less than 1.0 pci/l. Three independent surface water surveillance samples were collected in All radionuclides detected are background. Fish and Invertebrates Gamma Analyses Fish and invertebrate samples are collected on a semi-annual basis, and were collected in May and September of Gamma Isotopic results for the Indicator location show no results for Cs-137, and K-40 with maximum levels less than 3.00 pci/g-wet for all samples collected. 2-2

8 BSEP - Summary Vegetation Gross Alpha, Gross Beta, & Gamma Analyses Vegetation samples were collected on a bi-annual basis and indicated the presence of typical annual occurrences of K-40 and the cosmogenic product Be-7. No man-made radionuclides were found in vegetation samples collected at Brunswick in Sediment Gamma Analyses Soil sediment is also collected twice per year, and a gamma analysis performed on each sample. For sediment samples collected in 2009, no presence of abnormal activity was detected. Thermoluminescent Dosimetry (TLD) Thermoluminescent dosimetry results for 2009 produced a yearly average exposure of 42.8 mr for all sites. This is less than the statewide average of 75 mr/year. Due to travel restrictions in 2009, TLD s were placed at Brunswick for only the first quarter of the year. This travel restriction prevented NCRPS staff from placing or retrieving TLDs for the second through fourth quarters of To reduce the possibility of a recurrence of this environmental monitoring gap, NCRPShas implemented a new ambient gamma monitoring regime. The new ambient monitoring regime will replace TLDs with optically stimulated luminescent dosimeters, which will be placed/retrieved on an annual basis starting in

31 Harris - Summary SHEARON HARRIS NUCLEAR PLANT NEW HILL, WAKE/CHATHAM COUNTY Progress Energy operates the Shearon Harris Nuclear Plant, located about 16 miles southeast of Raleigh, N.C. The plant consists of one pressurized water reactor with a design rating of approximately 900 megawatts - electrical. Carolina Power and Light, which became Progress Energy, created an approximately 4,000-acre reservoir (Harris Lake), which is used for cooling tower makeup. Commercial production began in early The monitoring program continued around the Harris Plant through all of calendar year A summary of the results for the air monitoring performed around the Harris Plant during this year is presented below. The mean gross beta activities in air for the co-located sites for 2009 are presented in the table below. Location NCRPS HNP % Difference (pci/m 3 ) (pci/m 3 ) SH-APLV-04 (Indicator) 1.32 E E SH-APLV-9261 (Control) 1.45 E E SH-APLV E E SH-APLV E-02 NA NA SH-APLV E E Air Particulate and Radioiodine The trends for the results of RPS and Progress Energy at the control and indicator sites are generally in agreement for The monthly air filter composites collected at sites 04 (indicator site) and 9261 (control site) did not provide any evidence of fission products during This finding was reinforced by the results of weekly gross beta analyses of low volume air particulate samples, with no gross beta analyses exceeding the investigation level of 0.5 pci/m 3. There were no iodine detections at either the control (SH-APLV-9261) or indicator (SH-APLV- 04) locations during Surface Water Surface water samples collected from the indicator site (SH-SW-45) did not contain detectable levels of fission or activation products during Tritium levels at sites SH-SW-44 and SH- SW-45 are at or near natural levels (250 pci/l). Tritium levels in Harris Lake averaged 4,170 pci/l and 5,500 pci/l for NCRPS and Progress Energy, respectively. Surface water low level iodine values were significantly less than 1 pci/l and there was general agreement between RPS and Progress Energy. 3-2

32 Harris - Summary Milk During 2009, there was no indication of fission or activation products in milk samples based on gamma isotopic results. The low-level radioiodine results were generally in agreement and were below 1 pci/l. Groundwater Groundwater wells around the plant did not indicate the presence of plant-related radionuclides during The tritium results at all ground water sites were near or below detection limits ( pci/l) and do not indicate any activity resulting from plant operations. Fish Fish collected during 2009 do not indicate the presence of fission or activation products. The Progress Energy and NCRPS results generally show good agreement. Food crop samples collected in 2009 also showed no presence of plant-related radionuclides. Sediment Sediment samples collected at Harris Nuclear Plant in 2009 showed no evidence of plant-related radionuclides with two exceptions: trace amounts of Cobalt-58, Cobalt-60, Cesium-137, and Antimony-125 were detected in two samples collected at location SH-SD-54 on Feburary 12, 2009, and July 21, 2009, respectively. These small amounts of man-made radionuclides are possibly due to releases of material from the plant waste treatment system into Harris Lake, which are then concentrated in the sediment. Thermoluminescent Dosimetry Thermoluminescent dosimetry results from around the Harris Plant during 2009 do not indicate the presence of elevated ambient gamma radiation. The yearly average for all TLD sites at Harris in 2009 is 57.8 milliroentgen, which is below the statewide average of 75 mr/year. Due travel restrictions in 2009, TLD s were placed at Harris for only the first quarter of the year. This travel restriction prevented NCRPS staff from placing or retrieving TLD s for the second through fourth quarters of To reduce the possibility of a recurrence of this environmental monitoring gap, NCRPS has implemented a new ambient gamma monitoring regime. The new ambient monitoring regime will replace TLDs with optically stimulated luminescent dosimeters, which will be placed/retrieved on an annual basis starting in

65 MCGUIRE NUCLEAR STATION

66 McGuire - Summary MCGUIRE NUCLEAR STATION HUNTERSVILLE, MECKLENBURG COUNTY Duke Power Company (Duke), a subsidiary of Duke Energy Corporation (DEC), operates the McGuire Nuclear Station (MNS) located about 17 miles northwest of Charlotte, NC, on Lake Norman. The plant consists of two pressurized water reactors with a net design rating of 1180 MW(e) each. Commercial power production was initiated by Unit 1 on December 1, 1981, and Unit 2 on March 1, The North Carolina Radiation Protection Section (NCRPS) has conducted an environmental radiation monitoring program around MNS since This environmental monitoring consists of sampling the following media: air particulate, surface water, milk, fish, crops/vegetation, soil/sediment, and thermoluminescent dosimetry (TLD). For a map of sampling locations around MNS, please see pages 4-4 and 4-5. Air Particulate and Air Radioiodine For 2009, all gross beta results for NCRPS air samples were below NCRPS's investigation level of 0.5 pci/m 3 and no appreciable upward trend was noted when compared with results from years past. MNS and NCRPS results are in general agreement as can be seen in the gross beta activity averages for air particulate samples collected in 2009: BETA AVERAGES FOR MCGUIRE AIR SAMPLING LOCATIONS, 2009 Location NCRPS Average (pci/m 3 ) MNS Average (pci/m 3 ) % Difference * MG-APLV-120 (Indicator) 2.09 E E MG-APLV-102 (Control) 2.39 E E MG-APLV E E MG-APLV E E MG-APLV-119 (not co-located with MNS) 1.98 E-2 *Please note that in this case "percent difference" refers to the difference from the average of the two measurements. Radioiodine was not detected in air samples collected at the control and indicator locations in No occurrences of radioiodine in air were detected in samples collected from co-located MNS air samplers. Additionally, no man-made activity was detected in gamma isotopic analyses of air samples collected around McGuire in

67 McGuire - Summary Surface Water Significant amounts of radioiodine were not detected in surface water samples collected at the indicator location (MG-SW-128) in Average tritium levels were low in 2009, with an indicator site (MG-SW-128) average of 1060 pci/l and a control site (MG-SW-135) average of 118 pci/l for No man-made radionuclides were detected in surface water samples collected in Milk For milk samples collected in 2009, no significant amount (above the investigation level of 10 pci/l) of radioiodine was detected. No man-made radionuclides were detected in surface water samples collected in Fish For fish samples collected in 2009, several samples were found to have small amounts of cesium-137. Cs-137 is commonly seen in small amounts in fish and its presence is probably due to past atmospheric nuclear weapons testing. The detected levels of these radionuclides were very low in all instances. Sediment For sediment samples and food crop collected in 2009, no man-made radionuclides were found. Thermoluminescent Dosimetry TLD results for 2009 produced a yearly average exposure of 65.0 mr for all sites. This is less than the statewide average of 75 mr/year. Due to travel restrictions in 2009, TLD s were placed at McGuire for only the first quarter of the year. This travel restriction prevented NCRPS employees from placing or retrieving TLD s for the second through fourth quarters of To reduce the possibility of a recurrence of this environmental monitoring gap, NCRPS has implemented a new ambient gamma monitoring regime. The new ambient monitoring regime will replace TLDs with optically stimulated luminescent dosimeters, which will be placed/retrieved on an annual basis starting in

93 GE / HITACHI URANIUM FUEL FABRICATION PLANT

94 GE - Summary GE / HITACHI FUEL FABRICATION PLANT CASTLE HAYNE, NC General Electric (GE) operates a nuclear fuel fabrication facility approximately six miles north of Wilmington in Castle Hayne, North Carolina. This facility was licensed in January 1969 by the U.S. Nuclear Regulatory Commission (NRC) to fabricate uranium fuel for commercial reactors. The results of monitoring activities surrounding the GE facility for 2009 are presented in the following section. Samples of air particulates, surface water, groundwater, sediment, TLDs and treated waste water were collected around GE during this period. Analysis for all samples began with a gross alpha and gross beta determination. Further analyses using inductively coupled plasma mass spectrometry (ICP-MS) to detect uranium were then performed if the gross alpha results exceeded the screening levels listed in Appendix C of this report. Air Filters There are two NCRPS air samplers located on the GE site. The indicator location is at Site 20, at the fence near the southern boundary of the site. The control air sampling location, Site 03, is located at the Site Dock on the Cape Fear River. The mean results for the gross alpha analysis in pci/m 3 are shown below along with the percent difference between NCRPS and GE results. Alpha Activity in Air for GE and NCRPS Control and Indicator Locations Location NCRPS GE Percent Difference GE-APLV E E % GE-APLV E E % GE-APLV E The mean air activities at NCRPS Sites 03 and 20 are both slightly higher than those at GE samplers. When the actual NCRPS results in the data set are examined they were alternately greater and then less than the GE results. The mean value for NCRPS sample results was calculated by averaging all filters collected during Monitoring continued at Site GE- APLV-11 at the Horticultural Crops Research Station. The maximum gross alpha value at this site was 9.20 ± 0.51 E-03 pci/m 3. This maximum value was slightly above the NCRPS screening level for gross alpha in air (0.01 pci/m 3 ) as listed in Appendix A. Surface Water Surface water samples collected at Sites 03 and 04 were all indicative of no evidence of elevated uranium levels at these sites. The gross alpha and beta results from NCRPS and GE were generally within two standard deviations at both of these sites during

95 GE - Summary Groundwater Groundwater samples collected near the process lagoons at Site PL3A and WT-6 during 2009, in most instances, were well below the 5 pci/l gross alpha screening level. NCRPS results were generally in agreement with those from General Electric. However in a few instances there were elevated numbers which are hard to substantiate due to the age, low flow rate and other properties of the well site that make it difficult to discern the difference in analysis results by each lab. Therefore general deductions were taken into account while looking at results that were deemed to be an anomaly at the time and in comparison to GE s results. Furthermore, NCRPS results for samples from well F-3 near the former fluoride area were well below the 5 pci/l screening level at 2.17 ± 0.91 E+00 pci/l and 2.92 ± 1.43 E+00. These were consistent with GE results for the samples as well. Waste Water Samples of wastewater collected at Site GE-WW-02 were all above the 5 pci/l screening level. NCRPS results were higher than the GE results only on most occasions. However, several sample collections were not analyzed for various reasons, which further makes it difficult to ascertain why these elevated levels occurred. The higher results for the NCRPS samples are suspected to be the result of different sampling and analytical techniques. The NCRPS results include the dissolved and suspended activity. Furthermore, the N.C. State Laboratory for Public Health (SLPH) uses natural uranium as its calibration source for gross alpha in water analyses. The GE contract laboratory, in contrast, uses Am-241 as its calibration isotope. The difference in calibration isotopes can potentially cause a difference in the activity results. Alpha spectroscopy results are unavailable for these samples due to equipment integration problems and personnel turnover in the laboratory analyst position at the State Lab. Soil and Vegetation All of the soil samples collected at Site 05 (Tinga Farm) and Site 06 (Marathon Road) were below the 15 pci/g-dry screening level according to NCRPS or GE results. The SLPH completely ashes the samples and uses the ash weight to calculate the activity. NCRPS gross alpha values for vegetation are higher in some cases than the GE results. This is due to differences in the analysis procedures employed by the SLPH and the contract analysis laboratory used by GE. General Electric uses the dry weight value, which is calculated by multiplying the ash weight by the dry to ash weight ratio. The higher mass calculated for the dry weight would produce the differences in the GE and NCRPS values. Sediment All sediment samples collected at Sites 03 (Site Boat Dock) and 04 (Public Boat Dock) were below the 15 pci/g screening level for gross alpha. For this reason, no uranium analyses were done. Sediment samples collected at site 02D, the process lagoon outfall, were above the screening level on two occasions. 5-3

96 GE - Summary TLD s The maximum exposure rate during the first quarter was 39.3 mr/year. There is no evidence of elevated ambient gamma readings in the GE environment, since this result was well below the statewide average of 75 mr/year. Due to travel restrictions in 2009, TLDs were placed at GNF for only the first quarter of the year. This travel restriction prevented NCRPS staff from placing or retrieving TLD s for the second through fourth quarters of To reduce the possibility of a recurrence of this environmental monitoring gap, NCRPS has implemented a new ambient gamma monitoring regime. The new ambient monitoring regime will replace TLDs with optically stimulated luminescent dosimeters, which will be placed/retrieved on an annual basis starting in

114 NORTH CAROLINA ENVIRONMENTAL SURVEILLANCE NETWORK

115 Statewide - Summary NORTH CAROLINA ENVIRONMENTAL RADIATION SURVEILLANCE NETWORK In the interest of public health, the North Carolina Radiation Protection Section (NCRPS) monitors ambient radiological levels in the environment statewide. This monitoring is accomplished via a statewide network of sampling sites. The 2009 results associated with each sample medium are discussed below. Air Particulate Statewide air particulate is collected monthly from four separate locations using a 24-hour grab sample procedure. This involves using a high volume air sampler with an 8 inch X 10 inch glass fiber filter. The average gross beta concentration measured in 27 air particulate samples collected from four different locations during the year was 2.30 x 10-3 picocuries per cubic meter (pci/m 3 ). The airborne concentrations of gross beta activity for the year are indicative of natural background and do not indicate any abnormal activities. Milk Milk is sampled monthly from seven different locations statewide. These samples are analyzed for gamma emitting radionuclides. Average concentrations of Potassium-40 (K-40) measured in 81 samples for 2009 was 1, picocuries per liter (pci/l), which is indicative of background levels. No analyzed samples contained measurements above investigation levels. Precipitation Statewide precipitation is collected monthly, depending on the amount of rainfall, from three different sites using a composite sampling procedure. The average gross beta concentrations measured in 21 samples collected in 2009 was 0.95 nanocuries per square meter (nci/m 2). Background levels for gross beta in precipitation have not been established. Sewage Treated sewage effluent water is sampled monthly from three different locations. In 2009, 34 samples were analyzed. Gross alpha, beta and gamma analyses are performed on the samples. The average concentrations were 0.95 pci/l for gross alpha and pci/l for gross beta. The alpha and beta concentrations were indicative of background radiation levels. The average gamma concentrations were 68.1 pci/l for Iodine-131 (I-131) and pci/l for Potassium 40 (K-40). The I-131 concentration was above the background level due to two elevated measurements of 437 and 238 pci/l at the Mecklenburg County site in May and September respectively. These two measurements were above the investigation level but below the 6-2

116 Statewide - Summary regulatory limit for I-131 in sewage effluent, and subsequent analyses did not show any ongoing elevated measurements. Surface Finished Water Statewide finished water is collected monthly from nine locations. Gross alpha and gross beta analyses are routinely performed on samples. The average gross alpha and beta concentrations measured in 16 samples analyzed in 2009 were 0.11 pci/l and 2.79 pci/l respectively. These concentrations were indicative of background radiation levels. Surface Raw Water Raw surface water is sampled monthly from seven locations. Routinely, gross alpha and beta analyses are performed on surface water samples. The average gross alpha and beta concentrations measured in 13 samples analyzed in 2009 were 0.29 pci/l and 3.08 pci/l respectively. Average gross alpha and beta activity levels are below the average background levels for the state. Shellfish Oysters are collected four times per year routinely. The average concentration for Potassium-40 was 1.7 pci per gram (pci/g), which is slightly above the average background concentration and well below the investigation limit for fish life in the state. Note: Blanks in the tabulated data below indicate the data was not available. 6-3

127 CATAWBA NUCLEAR STATION

128 Catawba - Summary CATAWBA NUCLEAR STATION LAKE WYLIE, SOUTH CAROLINA Duke Power Company (Duke), a subsidiary of Duke Energy Corporation (DEC), operates the Catawba Nuclear Station (CNS) located one mile from the North Carolina border and about 19 miles southwest of Charlotte on Lake Wylie. The plant consists of two pressurized water reactors with a net design rating of 1129, megawatts-electrical each. Commercial power production was initiated by Unit 1 on June 29, 1985, and Unit 2 on Aug. 19, NCRPS conducts a limited air particulate and thermoluminescent dosimeter (TLD) monitoring program of CNS for the region of North Carolina in close proximity (less than 10 miles from CNS) to the plant. NCRPS collects and analyzes low volume air particulate samples from two locations on a weekly basis and TLD s from five locations on a quarterly basis for Catawba. None of these locations are co-located with Duke sampling sites. For 2009, all gross beta results for NCRPS air samples were below the NCRPS investigation level of 0.5 pci/m 3, and no appreciable upward trend was noted when compared with results from years past. For 2009, the average gross beta activity was 1.83 E-2 pci/m 3 at location CT- APLV-01 and 1.88 E-2 pci/m 3 at location CT-APLV-09. Composite gamma analyses of Catawba air particulate samples were not performed in 2009 by the State Radiochemistry Laboratory. Thermoluminescent dosimetry results for 2009 produced a yearly average exposure of 67.0 milliroentgens (mr) for all sites. This is less than the statewide average of 75 mr/year. Due to travel restrictions in 2009, TLD s were placed at Catawba for only the first quarter of the year. This travel restriction prevented NCRPS staff from placing or retrieving TLD s for the second through fourth quarters of To reduce the possibility of a recurrence of this environmental monitoring gap, NCRPS has implemented a new ambient gamma monitoring regime. The new ambient monitoring regime will replace TLDs dosimeters with optically stimulated luminescent dosimeters, which will be placed/retrieved on an annual basis starting in

133 PCS PHOSPHATE

134 PCS Phosphate - Summar y PCS PHOSPHATE AURORA, BEAUFORT COUNTY It has long been recognized that mining operations can redistribute natural radionuclides found in ore bodies. In the case of phosphate ore, this process can bring uranium and radium into contact with man and his environment. For this reason, the North Carolina Radiation Protection Section conducts a monitoring program around the Potash Corporation of Saskatchewan Phosphate (PCS Phosphate) mining facility near Aurora, in Beaufort County. In 1995, PCS purchased the Aurora phosphate operations. This was part of the purchase of Texasgulf; a Texas-based sulfur-mining company which had operated the site up to that point. This purchase included land previously owned by the North Carolina Phosphate Corporation. The PCS Phosphate site is located in Beaufort County near Aurora, North Carolina. Operations include the phosphate mine, up-grading facilities, and several fertilizing materials plants. Mining of phosphate ore is accomplished by removing approximately 40 feet of overburden using bucket wheel excavators. The ore is then removed from the mine area by dredge or dragline. To keep the mine area dewatered, ground water is continuously withdrawn from the Castle Hayne aquifer. This water is then used in the phosphoric acid plant and plant cooling systems. The milling process begins by transporting a slurry of sandy ore and water to the mill by use of a conveyor belt. The material is then washed and screened. Quartz sand is separated from the phosphate rich material by means of floatation, and the phosphate materials are then dried or calcined. Calcined phosphate rock can be shipped to customers as is, or it can be processed further onsite. Fertilizer is made by reacting phosphate rock with sulfuric acid, forming a weak phosphoric acid with gypsum as a by-product. The weak phosphoric acid is further processed to make different grades of phosphoric acid for sale to industry and agriculture sectors. Other products such as ammonium polyphosphate solution, and dry phosphate rock and diammonium phosphate are made from the ore material after processing. Some of the gypsum can be used for agricultural purposes by peanut farmers. Products are shipped from the site by truck, rail, and barge for distribution. A comprehensive special study of radioactivity in the environment was done around the site and on land owned by the NCPC in Periodic monitoring has still been maintained since then. In 2009, four air samples were collected at the site. None of these samples showed activity above the investigation levels. In 2009, the environmental monitoring program at PCS Phosphate was placed on hiatus due to staff reductions and budgetary concerns. In the face of these staffing and funding issues, RPS management made the decision to concentrate future monitoring efforts on fixed nuclear 8-2

137 B-52 CRASH SITE FARO, NC

138 B-52 - Summary B-52 CRASH SITE FARO, WAYNE COUNTY On January 24, 1961, a U.S. Air Force B-52 aircraft carrying two nuclear weapons crashed near Faro, North Carolina. The weapons were never detonated, according to information supplied by the U.S. Department of Defense. One piece of radioactive uranium from one of the weapons penetrated to a depth greater than 50 feet in the swamp area and was never recovered. For the purpose of finding possible radioactive contamination in groundwater supplies near the site, an extensive study of groundwater around the crash site was implemented on November 8, 1983, by NCRPS with the assistance of the Wayne County Health Department. Follow up sampling has been performed at an annual frequency overall since then. To this point, there has been no detection of any nuclides other than those expected from natural sources in the environment. On March 11, 2009, four groundwater and one surface water samples were collected from locations near the crash site. Residential wells sampled were chosen based on whether the owners were at home when sampling personnel arrived and whether the owner was using groundwater. All owners were very cooperative in providing samples from their wells. In some cases, groundwater wells used for watering livestock were used even if the homeowner used county water for drinking. All samples were analyzed for radioactivity at the N.C. State Laboratory of Public Health using established radioanalytical procedures. The samples were analyzed for alpha and beta activity. There is no indication of the presence of elevated levels of radioactivity, such as from the disintegration of nuclear weapons components in these samples. On the contrary, these levels are fully consistent with naturally occurring radioactivity in groundwater samples. The results of the groundwater sampling done to this point indicate that there is no evidence of contamination at this time. In 2009, the environmental monitoring program at the Faro Site was placed on hiatus due to NCRPS staff reductions and budgetary concerns. It is hoped that if funding and staffing return to pre-2009 levels, monitoring at the Faro Site can resume in the future. 9-2
