Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Oyster Creek Generating Station (OCGS) by AmerGen Energy Company covers the period 01 January 2006 through 31 December 2006. During that time period, 1180 analyses were performed on 1021 samples. In assessing all the data gathered for this report and comparing these results with historical data, it was concluded that the operation of OCGS had no adverse radiological impact on the environment.

Surface and well water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No fission or activation products were detected. No tritium activity was detected above the LLD of 200 pCi/L in any ground or surface water indicator sample. Tritium was detected at a very low level in one surface water control sample that is outside the influence of the facility. Data from previous years indicates that the yearly average tritium concentration is not significantly different from previous years and is due to nuclear weapons testing and Chernobyl.

Fish (predator and bottom feeder), clams, crabs, and sediment samples were analyzed for concentrations of gamma emitting nuclides. No fission or activation products were detected in fish, clams, crabs, or sediment.

Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. Cosmogenic Be-7 was detected at levels consistent with those detected in previous years. No fission or activation products were detected.

High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity.

Strontium-89 and strontium-90 and gamma analyses were performed on quarterly composites of air particulate samples. All strontium-89 and strontium-90 results were below the minimum detectable activity.

Vegetation samples were analyzed for gamma emitting nuclides, strontium-89, and strontium-90. Concentrations of naturally occurring K-40 were consistent with those detected in previous years. All strontium-89 results were below the minimum detectable activity. Strontium-90 activity was detected at low levels in both control and indicator stations, consistent with previous values. During December 2006, AmerGen initiated an evaluation of cesium-1 37 (Cs-1 37) in environmental samples from the Finninger Farm property adjacent to the Oyster Creek Generating Station (OCGS), which is entirely owned by AmerGen Energy Company. The evaluation was prompted by analytical detection of a Cs-137 concentration in a sample of leaves from a sassafras tree that was higher than that typically observed in vegetables normally collected as part of the OCGS Radiological Environmental Monitoring Program (REMP). Although sassafras 1

leaves had never been sampled as part of the REMP, they were sampled in the fall of 2006 as an alternative to vegetables from a garden maintained by the OCGS. Deer had consumed the vegetables in that garden during August.

Through extensive sampling and analysis it was determined that the Cs-1 37 concentrations found in the environmental samples taken on AmerGen property are the result of atmospheric nuclear weapons testing and the Chernobyl accident. The results of these samples are documented and discussed in the AmerGen document, "Evaluation of Cesium-137 in Environmental Samples from the AmerGen Property East of the Oyster Creek Generating Station, Final Report". These alternative samples were not included as part of the routine REMP. Tree leaves are from perennial plants, not annual broadleaf vegetation (i.e., cabbage, lettuce) which is required for the program.

Environmental gamma radiation measurements were performed quarterly using thermoluminescent dosimeters. Levels detected were consistent with those observed in previous years.

II.

Introduction The Oyster Creek Generating Station (OCGS), consisting of one boiling water reactor owned and operated by AmerGen Energy Company, is located on the Atlantic Coastal Plain Physiographic Province in Ocean County, New Jersey, about 60 miles south of Newark, 9 miles south of Toms River, and 35 miles north of Atlantic City. It lies approximately 2 miles inland from Barnegat Bay. The site, covering approximately 781 acres, is situated partly in Lacey Township and, to a lesser extent, in Ocean Township. Access is provided by U.S. Route 9, passing through the site and separating a 637-acre eastern portion from the balance of the property west of the highway. The station is about 1/4 mile west of the highway and 11/4 miles east of the Garden State Parkway. The site property extends about 21/2 miles inland from the bay; the maximum width in the north-south direction is almost 1 mile. The site location is part of the New Jersey shore area with its relatively flat topography and extensive freshwater and saltwater marshlands. The South Branch of Forked River runs across the northern side of the site and Oyster Creek partly borders the southern side.

A preoperational Radiological Environmental Monitoring Program (REMP) for OCGS was established in 1966, and continued for two years prior to the plant becoming operational in 1969. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Global Dosimetry, and Environmental Inc.

(Midwest Labs) on samples collected during the period 01 January 2006 through 31 December 2006.

A.

Objectives of the REMP The objectives of the REMP are to:

1.

Determine whether any significant increase occurs in the concentration of radionuclides in major pathways.

2.

Identify and evaluate the buildup, if any, of radionuclides in the local environment, or any changes in normal background radiation levels.

3.

Verify the adequacy of the plant's controls for the release of radioactive materials.

4.

Fulfill the obligations of the radiological surveillance sections of Oyster Creek's Offsite Dose Calculation Manual (ODCM).

B.

Implementation of the Objectives The implementation of the objectives is accomplished by:

3

1.

Identifying significant exposure pathways.

2.

Establishing baseline radiological data of media within those pathways.

3.

Continuously monitoring those media before and during Station operation to assess Station radiological effects (if any) on man and the environment.

C.

Discussion 1.

General Program The Radiological Environmental Monitoring Program (REMP) was established in 1966, three years before the plant became operational. This preoperational surveillance program was established to describe and quantify the radioactivity, and its variability, in the area prior to the operation of Oyster Creek Generating Station (OCGS). After OCGS became operational in 1969, the operational surveillance program continued to measure radiation and radioactivity in the surrounding areas.

A variety of environmental samples are collected as part of the REMP at OCGS. The selection of sample types is based on the established pathways for the transfer of radionuclides through the environment to humans. The selection of sampling locations is based on sample availability, local meteorological and hydrological characteristics, local population characteristics, and land usage in the area of interest. The selection of sampling frequencies for the various environmental media is based on the radionuclides of interest, their respective half-lives, and their behavior in both the biological and physical environment.

2.

Preoperational Surveillance Program The federal government requires nuclear facilities to conduct radiological environmental monitoring prior to constructing the facility. This preoperational surveillance program is aimed at collecting the data needed to identify pathways, including selection of the radioisotope and sample media combinations to be included in the environmental surveillance program conducted after facility operation begins. Radiochemical analyses performed on the environmental samples should include not only those nuclides expected to be released during facility operation, but should also 4

include typical radionuclides from nuclear weapons testing and natural background radioactivity. All environmental media with a potential to be affected by facility operation as well as those media directly in the major pathways, should be sampled on at least an annual basis during the preoperational phase of the environmental surveillance program.

The preoperational surveillance design, including nuclide/media combinations, sampling frequencies and locations, collection techniques, and radioanalyses performed, should be carefully considered and incorporated in the design of the operational surveillance program. In this manner, data can be compared in a variety of ways (for example, from year to year, location to location, etc.) in order to detect any radiological impact the facility has on the surrounding environment. Data collection during the preoperational phase should be planned to provide a comprehensive database for evaluating any future changes in the environment surrounding the nuclear facility.

OCGS began its preoperational environmental surveillance program three years before the plant began operating in 1969.

Data accumulated during those early years provide an extensive database from which environmental monitoring personnel are able to identify trends in the radiological characteristics of the local environment. The environmental surveillance program at OCGS will continue after the plant has reached the end of its economically useful life and decommissioning has begun.

3.

Consideration of Plant Effluents Effluents are strictly monitored to ensure that radioactivity released to the environment is as low as reasonably achievable and does not exceed regulatory limits. Effluent control includes the operation of monitoring systems, in-plant and environmental sampling and analyses programs, quality assurance programs for effluent and environmental programs, and procedures covering all aspects of effluent and environmental monitoring.

Both radiological environmental and effluent monitoring indicate that the operation of OCGS does not result in significant radiation exposure of people or the environment surrounding OCGS and is well below the applicable levels set by the Nuclear Regulatory Commission (NRC) and the Environmental Protection Agency (EPA).

5

The highest 2006 potential dose due to any plant effluent was calculated to be 0.02 mRem, to the thyroid, which is 0.1% of the applicable limit found in 10 CFR 50, Appendix I. Also during 2006, there was no measurable direct radiation dose due to OCGS beyond the site boundary as shown by offsite thermoluminescent dosimeter (TLD) readings. The offsite dose due to effluents is an extremely low fraction of the 40 CFR 190 limits. Therefore, the combined direct radiation and effluent dose due to OCGS was in compliance with 40 CFR 190, as well as 10 CFR 50, in 2006.

Additionally, comparison of environmental sampling results to iodine and particulate gaseous effluents released, showed no radioactivity attributable to the operation of OCGS. Both elevated and ground-level release paths were considered in this review, with total iodines released of 4.61 mCi and total particulates with half-lives greater than 8 days released of 5.46 mCi. (1 mCi is one/one-thousandth of a Ci.)

Ill.

Program Description A.

Sample Collection Samples for the OCGS REMP were collected for AmerGen Energy Company by on-site personnel and Normandeau Associates, RMC Environmental Services Division (RMC). This section describes the general collection methods used to obtain environmental samples for the OCGS REMP in 2006. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-1 and B-2, Appendix B. The collection procedures are listed in Table B-3.

Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, well water, fish, clams, crabs, and sediment. One gallon water samples were collected monthly from two surface locations (33 and 94), semiannually at two surface water locations (23 and 24), and quarterly from three well water locations (1, 37, and 38).

Control locations were 94 and 37. All samples were collected in plastic bottles, which were rinsed at least twice with source water prior to collection. Fish samples comprising the flesh of two groups, bottom feeder and predator, were collected semiannually at three locations (33, 93 and 94 (control). Clams were collected semiannually from three locations (23, 24, and 94 (control). One annual crab sample was collected from one location (93). Sediment samples were collected at four locations 6

semiannually (23, 24, 33, and 94 (control).

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate and airborne iodine. Airborne iodine and particulate samples were collected and analyzed weekly at seven locations (C, 3, 20, 66, 71, 72, and 73). The control location was C.

Airborne iodine and particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The filters were replaced weekly and sent to the laboratory for analysis.

Terrestrial Environment The terrestrial environment was evaluated by performing radiological analyses on samples of garden vegetation.

No commercial dairy operations and no dairy animals producing milk for human consumption are located within a 5 mile radius of the plant.

Therefore, vegetation samples were collected in lieu of milk. Vegetation samples were collected, when available, at three locations (35, 36, and 66). Station 36 was the control location. All samples were collected in 18" x 24" new unused plastic bags and shipped promptly to the laboratory.

Ambient Gamma Radiation Direct radiation measurements were made using Panasonic Model 814 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLDs were placed on and around the OCGS site and were categorized as follows:

A site boundary, ring consisting of 16 locations (1,51, 52, 53, 54, 55, 56, 57, 58, 59, 61,62, 63, 64, 65 and 66) near the boundary.

An intermediate distance ring consisting of 16 locations (4, 5, 22, 47, 48, 68, 73, 74, 75, 79, 82, 84, 85, 86, 98, and 99) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.

Special interest stations consisting of 15 locations (3, 6, 8, 9, 11, 46, 71, 72, 78, 81, 88, 89, 90, 92, and T1) representing special interest areas such as population centers, state parks, etc.

7

Background (Control) stations consisting of two locations (C and 14) greater than 20 miles distant from the site.

Indicator TLDs were placed systematically, with at least one station in each of 16 meteorological compass sectors in the general area of the site boundary. TLDs were also placed in each meteorological sector in the 3 % to 5 mile range, where reasonable highway access would permit, in areas of public interest and population centers. Background locations were located greater than twenty miles distant from the OCGS and generally in an upwind direction from the OCGS.

Two TLDs - each comprised of three CaSO4 thermoluminescent phosphors enclosed in plastic - were placed at each location approximately three to eight feet above ground level. The TLDs were exchanged quarterly and sent to Global Dosimetry for analysis.

B.

Sample Analysis This section describes the general analytical methodologies used by TBE and Environmental Inc. (Midwest Labs) to analyze the environmental samples for radioactivity for the OCGS REMP in 2006. The analytical procedures used by the laboratories are listed in Table B-3.

In order to achieve the stated objectives, the current program includes the following analyses:

1.

Concentrations of beta emitters in air particulates.

2.

Concentrations of gamma emitters in surface and well water, fish, clams, crabs, sediment, air particulates, and vegetation.

3.

Concentrations of tritium in surface and well water.

4.

Concentrations of 1-131 in air iodine cartridges.

5.

Concentrations of strontium in air particulates and vegetation.

6.

Ambient gamma radiation levels at various locations around the OCGS.

C.

Data Interpretation For trending purposes, the radiological and direct radiation data collected during 2006 were compared with data from past years. The results of environmental sampling show that radioactivity levels have not increased 8

from the background radioactivity detected prior to the operation of OCGS.

The operation of OCGS continues to have no measurable radiological impact upon the environment.

Several factors were important in the interpretation of the data:

1.

Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD is intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criterion for the presence of activity. All analyses were designed to achieve the required OCGS detection capabilities for environmental sample analysis.

The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

2.

Net Activity Calculation and Reporting of Results Net activity for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations may result in sample activity being lower than the background activity, which results in a negative number.

An MDC was reported in all cases where positive activity was not detected.

Gamma spectroscopy results for each type of sample were grouped as follows:

For surface and well water 12 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Cs-134, Cs-137, Ba-140, and La-140 were reported.

For fish eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-134, and Cs-1 37 were reported.

For clams eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, and Cs-1 37 were reported.

9

For crabs eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, and Cs-1 37 were reported.

For sediment seven nuclides, Be-7, K-40, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-1 37 were reported.

For air particulate six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-134, and Cs-137 were reported.

For air cartridges one nuclide, 1-131 was reported.

For vegetation six nuclides, K-40, 1-131, Cs-134, Cs-137, Ba-140, and La-140 were reported.

Means and standard deviations of the results were calculated. The standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.

D.

Program Exceptions For 2006 the OCGS REMP had a sample recovery rate in excess of 99%.

Exceptions are listed below:

1.

Air particulate and air iodine samples had low volume for the following period and location, due to a blown fuse:

05/10/06 - 05/17/06 (week 9), Location 73 05/17/06 - 05/23/06 (week 21), Location 71 05/17/06 - 05/23/06 (week 21), Location 73 This resulted in specified LLDs not being met.

2.

Air particulate and air iodine samples were not available for the following period and location, due to the State of New Jersey being shut down due to the state budget crisis:

06/28/2006 - 07/05/2006 (week 27), Location 3

3.

Air particulate sample Sr-89 LLD was missed for the following period and location, due to low chemical recovery:

012/28/2005 - 03/28/2006, Location 3

4.

Vegetation samples 1-131 LLDs were missed for the following periods and locations, due to the discontinuation and poor performance of two types of filter paper used in the 1-131 analysis. Although sample aliquots were increased (up to 8 liters, when possible) and count times extended (up to 64 hours7.407407e-4 days <br />0.0178 hours <br />1.058201e-4 weeks <br />2.4352e-5 months <br />, in some cases), LLD requirements were missed due to low chemical yield 10

and decay of the iodine during the investigation. TBE initiated NCR 06-13 to investigate and document this event.

07/19/2006 - Location 66

5.

August - September 2006, Location 35: Program vegetation samples were unavailable due to deer eating the garden. During December 2006, AmerGen initiated an evaluation of cesium-1 37 (Cs-1 37) in sassafras leaf samples from REMP sampling location

1. 35 on the Finninger Farm property adjacent to the Oyster Creek Generating Station (OCGS). The evaluation was prompted by analytical detection of a Cs-137 concentration in a sample of leaves that was higher than that typically observed in vegetables normally collected as part of the OCGS Radiological Environmental Monitoring Program (REMP). Although sassafras leaves had never been sampled as part of the REMP, they were sampled in the fall of 2006 as an alternative to vegetables from a garden maintained by the OCGS. Deer had consumed the vegetables in that garden during August.

Through extensive sampling and analysis it was determined the Cs-1 37 concentrations found in the environmental samples taken on AmerGen property are the result of atmospheric nuclear weapons testing and the Chernobyl accident. The results of these samples are documented and discussed in the AmerGen document, "Evaluation of Cesium-137 in Environmental Samples from the AmerGen Property East of the Oyster Creek Generating Station, Final Report".

6.

Vegetation samples Sr-89/90 analyses were not performed for the following period and location, due to limited sample volume:

08/16/2006, Location 66

7.

TLD samples were lost for the following periods and locations, due to vandalism:

01 /10/2006 - 04/20/2006, Location 4 01 /10/2006 - 04/20/2006, Location 5 01 /10/2006 - 04/20/2006, Location 46 01/10/2006 - 04/20/2006, Location 47 01/10/2006 - 04/20/2006, Location 48 04/20/2006 - 07/13/2006, Location 4 04/20/2006 - 07/13/2006, Location 5 04/20/2006 - 07/13/2006, Location 46 04/20/2006 - 07/13/2006, Location 47 04/20/2006 - 07/13/2006, Location 48 07/13/2006 - 10/09/2006, Location 72*

07/13/2006 - 10/09/2006, Location 73 07/13/2006 - 10/09/2006, Location 75 11

10/20/2006 - 01/13/2007, Location 6

• Additionally, one of the two TLDs at Location 72 was missing during collection of third quarter TLDs. This did not result in a missed sample point.

8.

Minimum amount of 250 grams of soft tissue for crab sample was not obtained. This did not affect any sample results.

Each program exception was captured under the corrective action process, which resulted in an investigation to understand the causes of the program exception. Sampling and maintenance errors were reviewed with the personnel involved to prevent recurrence.

The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program implementation.

E.

Program Changes There were no changes to the routine REMP program in 2006. A separate program was instituted to monitor groundwater in the surrounding environs, during 2006. This program and any sampling and analysis results are discussed in Appendix F, Annual Radiological Groundwater Protection Program Report.

IV.

Results and Discussion A.

Aquatic Environment

1.

Surface Water Samples were taken via grab sample methodology at two locations (33 and 94) on a monthly schedule. In addition, grab samples were collected semi-annually at two locations (23 and 24). Of these locations 23, 24, and 33, located downstream, could be affected by Oyster Creek's effluent releases. The following analyses were performed:

Tritium Samples from all locations were analyzed for tritium activity (Table C-1.1, Appendix C). Tritium activities were consistent with those detected in previous years, with only one sample result greater than 12

the MDC of 200 pCi/liter.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-1.2, Appendix C). All nuclides were less than the MDC.

Surface water sampling began in 1966, and the samples were analyzed for tritium as well as other radioactivity. During this preoperational program, tritium was detected at an average concentration of 1.05E+3 pCi/liter. At that time, counting instrumentation was not as sensitive as it now, and the minimum detectable concentration was 1 E+3 pC/liter versus 2E+2 pCi/liter used today. By decay correcting this average concentration to 1.11 E+2 pCi/liter, and comparing it to 2006 sampling results, it can be seen that the inventory of tritium in the environment is due to fallout from past atmospheric nuclear weapons testing and Chernobyl, and is decreasing with time.

2.

Well Water Quarterly samples were composited from monthly grab samples at three locations (1, 37, and 38). Two locations (1 and 38) could be affected by Oyster Creek's effluent releases. The following analyses were performed:

Quarterly samples from all locations were analyzed for tritium activity (Table C-I1.1, Appendix C). No tritium activity was detected.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-11.2, Appendix C). All nuclides were less than the MDC.

Well water was sampled during the preoperational program and throughout the 37 years of the plant's operational program. Tritium sampling results during the preoperational years, yielded results all less than the minimum detectable concentration of 1 E+3 pCi/liter.

2006 results are all less than the current MDC of 200 pCi/liter.

3.

Fish Fish samples comprised of American eel and flounder (bottom feeder) and weakfish, striped bass, bluefish, sea trout, perch, kingfish, and. sea bass (predator) were collected at three locations (33, 93, and 94) semiannually. Locations 93 and 33 could be affected by Oyster Creek's effluent releases. The following analysis was performed:

Gamma Spectrometry.

The edible portions of fish samples from three locations were analyzed for gamma emitting nuclides (Table C-111.1, Appendix C).

Naturally occurring potassium-40 was found at all stations and ranged from 2,360 to 5,120 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.

No fish were sampled during the preoperational sampling program for OCGS.

4.

Clams and Crabs Clams were collected at three locations (23, 24, and 94) semiannually. Crabs were collected at one location (93) annually.

Locations 23, 24, and 93 could be affected by Oyster Creek's effluent releases. The following analysis was performed:

Gamma Spectrometry The edible portions of clam samples from all three locations were analyzed for gamma emitting nuclides (Table C-111.2, Appendix C).

Naturally occurring potassium-40 was found at all stations and ranged from 1,150 to 2,160 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found. Historical levels of Co-60 in clams are shown in Figure C-1, Appendix C.

Preoperational clam sample results for potassium-40 ranged from 600 to 9,800 pCi/kg wet, which are consistent with current sample results. Decay corrected values for positive cesium-1 37 results during the preoperational years (<8 to 168 pCi/kg) are consistent with 2006 cesium-1 37 sample results of <29 to <66 pCi/kg.

The edible portions of crab samples from one location were 14

analyzed for gamma emitting nuclides (Table C-111.2, Appendix C).

Naturally occurring potassium-40 was found at a concentration of 1,770 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.

Crabs were not sampled during the preoperational years of the OCGS environmental monitoring program.

5.

Sediment Aquatic sediment samples were collected at four locations (23, 24, 33, and 94) semiannually. Of these locations, stations 23, 24, and 33 located downstream, could be affected by Oyster Creek's effluent releases. The following analysis was performed:

Gamma Spectrometry Sediment samples from all four locations were analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C). Nuclides detected were naturally occurring Be-7 and K-40.

Potassium-40 was found at all stations and ranged from 794 to 16,500 pCi/kg dry. No fission or activation products were found.

Figure C-3, Appendix C graphs Cs-137 concentrations in sediment from 1984 through 2006 and figure C-2, Appendix C graphs Co-60 concentrations in sediment from 1981 through 2006.

While aquatic sediment sampling was part of the preoperational program, samples were not analyzed for gamma emitting nuclides until 1981.

In conclusion, aquatic monitoring results for 2006 of surface water, well water, fish, clams and crabs, and aquatic sediment showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing and Chernobyl and were consistent with levels measured prior to the operation of OCGS, and with levels measured in past years. No radioactivity attributable to activities at OCGS was detected in any aquatic samples during 2006 and no adverse long-term trends are shown in the aquatic monitoring data.

B.

Atmospheric Environment

1.

Airborne

a.

Air Particulates Continuous air particulate samples were collected from seven locations on a weekly basis. The seven locations were separated into three groups: Group I represents locations near the OCGS site boundary (20 and 66), Group II represents the locations at an intermediate distance from the OCGS site (71, 72, and 73), and Group III represents the control and locations at a remote distance from OCGS (C and 3). The following analyses were performed:

Gros Beta Weekly samples were analyzed for concentrations of beta emitters (Table C-V.1 and C-V.2, Appendix C).

Detectable gross beta activity was observed at all locations.

Comparison of results among the three groups aid in determining the effects, if any, resulting from the operation of OCGS. The results from the Site Boundary locations (Group I) ranged from <6 to 30 E-3 pCi/m 3 with a mean of 15 E-3 pCi/m. The results from the Intermediate Distance locations (Group II) rancied from <6 to 157 E-3 pCi/m 3 with a mean of 17 E-3 pCi/in. The results from the Distant locations (Group Ill) ranged from <5 to 29 E-3 pCi/m 3 with a mean of 15 E-3 pCi/m 3. Comparison of the 2006 air particulate data with previous years data indicate no effects from the operation of OCGS (Figure C-5, Appendix C). In addition a comparison of the weekly mean values for 2006 indicate no notable differences among the three groups (Figure C-4, Appendix C). (The 157 E-3 pCi/m 3 result in Group II was due to low sample volume.)

Strontium-89 and Strontium-90 Weekly samples were composited quarterly and analyzed for strontium-89 and strontium-90 (Table C-V.3, Appendix C).

No strontium was detected.

Gamma Spectrometry.

Weekly samples were composited quarterly and analyzed for 16

gamma emitting nuclides (Table C-V.4, Appendix C).

Naturally occurring Be-7 due to cosmic ray activity was detected in most samples. The values ranged from 38 to

<112 E-3 pCi/mi3. All other nuclides were less than the MDC.

Air sample filters have been analyzed for gross beta activity since the inception of the preoperational environmental monitoring program in 1966. The preojPerational data values ranged from 1.90E-2 to 2.77E-1 pCi/m. 2006 gross beta activity values ranged from <5E-3 to 1.57E-1 pCi/m 3, with the higher value due to low sample volume. 2006 data values are consistent with historical operational data.

b.

Airborne Iodine Continuous air samples were collected from seven (C, 3, 20, 66, 71, 72, and 73) locations and analyzed weekly for 1-131 (Table C-VI.1, Appendix C). All results were less than the MDC.

The preoperational environmental monitoring program for OCGS did not include analysis of air media for iodine-131.

In conclusion, the atmospheric monitoring data are consistent with preoperational and prior operational data and show no long-term trends in the environment attributable to the operation of OCGS.

2.

Terrestrial

a.

Vegetation Samples were collected from three locations (35, 36, and 66) when available. The following analyses were performed:

Strontium-89 and Strontium-90 Vegetation samples from all locations were analyzed for concentrations of strontium-89 and strontium-90 (Table C-VII.1, Appendix C). All strontium-89 results were less than the MDC. Strontium-90 was detected in eight of twenty samples. The values ranged from <2 to 124 pCi/kg wet, which is consistent with historical data.

17

Gamma Spectrometry Vegetation samples from locations 35, 36, and 66 were analyzed for concentrations of gamma emitting nuclides (Table C-VII.1, Appendix C). Naturally occurring K-40 activity was found in all samples and ranged from 1,930 to 8,480 pCi/I. No Cs-137 activity was detected in any routine REMP samples. (See Section III.D.4.) All other nuclides were less than the MDC.

Preoperational vegetation sample analyses did not include strontium-89, strontium-90, or gamma spectroscopy.

In conclusion, terrestrial monitoring results for 2006 of vegetation samples, showed only naturally occurring radioactivity and radioactivity associated with fallout from past atmospheric nuclear weapons testing and Chernobyl.

The radioactivity levels detected were consistent with levels measured in past years, and no radioactivity attributable to activities at OCGS was detected in any terrestrial samples.

The terrestrial monitoring data show no adverse long-term trends in the terrestrial environment.

C.

Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic Model 814 (CaSO4) thermoluminescent dosimeters. Forty-nine TLD locations were monitored around the site. Results of TLD measurements are listed in Tables C-VIII.1 to C-VIII.3, Appendix C.

All TLD measurements were below 20 mR/standard quarter, with a range of 9.3 to 22.4 mR/standard quarter. 2006 gamma radiation data from the control location were plotted along with similar data from the Site, Intermediate Distance, and Outer Ring Locations (Figure C-6, Appendix C). Historical ambient gamma radiation data from the control location was plotted along with similar data from the Site, Intermediate Distance and Outer Ring Locations (Figure C-7, Appendix C). In conclusion, the 2006 TLD results are consistent with preoperational and past operational measurements of direct radiation.

D.

Land Use Survey A Land Use Survey, conducted during 2006 around the Oyster Creek Generating Station (OCGS), was performed by Normandeau Associates, RMC Environmental Services Division for Exelon Nuclear. The purpose of 18

the survey was, in part, to determine the location of animals producing milk for human consumption in each of the sixteen meteorological sectors out to a distance of 5 miles from the OCGS. None were observed.

Another purpose of the survey was to determine the location of gardens greater than 500 square feet in size producing broad leaf vegetation, as well as the closest residence within each of the sixteen meteorological sectors. The distance and direction of all locations from the OCGS Reactor Building were positioned using Global Positioning System (GPS) technology. There were no changes required to the OCGS REMP, as a result of this survey. In conclusion, the results of this survey are summarized below.

Summary of Results - Inter-laboratory Comparison Program The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation and water matrices (Appendix E). The PE samples, supplied by Analytics Inc.,

Environmental Resource Associates (ERA) and DOE's Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria:

19

1.

Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of TBE's result and Analytics' known value. Since flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.

2.

ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, state specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.

3.

DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.

The MAPEP defines three levels of performance: Acceptable (flag =

"A"), Acceptable with Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value.

Performance is acceptable with warning when a mean result falls in the range from +/-20% to +/-30% of the reference value (i.e., 20% <

bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.

For the primary laboratory, 24 out of 28 analytes met the specified acceptance criteria. Four samples did not meet the specified acceptance criteria for the following reasons:

1. Teledyne Brown Engineering's MAPEP Series 15 January 2006 soil Cs-1 34 was evaluated as a false positive, although TBE considered the result a non-detect due to the peak not being identified by the gamma software. MAPEP suggests the Bi-214 is not being differentiated from the Cs-1 34 peak. When the ratio of activity to uncertainty exceeds 3, TBE will use a key line analysis rather than a weighted mean analysis when evaluating MAPEP non-detects.

2. Teledyne Brown Engineering's MAPEP Series 15 January 2006 20

Sr-90 in vegetation result of 2.22 Bq/kg exceeded the upper acceptance range of 2.029 Bq/kg. The samples were analyzed in triplicate and the results averaged. One high result of 2.43 Bq/kg biased the submitted results on the high side. TBE was unable to determine the cause for the higher result. The Sr-90 in vegetation results for MAPEP Series 14 and MAPEP Series 16 were acceptable. No client samples were analyzed during the MAPEP Series 14 time period.

3. Teledyne Brown Engineering's MAPEP Series 15 January 2006 Pu-238 and Pu-239/240 in vegetation result of 2.22 Bq/kg failed the required acceptance ranges. TBE was evaluating the current preparation method for vegetation samples, which proved insufficient for the analyses. TBE does not perform isotopic Pu on client's vegetation samples.

For the secondary laboratory, 20 out of 25 analytes met the specified acceptance criteria. Seven samples did not meet the specified acceptance criteria for the following reasons:

1.

Environmental Inc.'s ERA November 2006 water 1-131 result of 28.4 pCi/liter exceeded the upper control limit of 27.3 pCi/liter. The reported result was an average of three analyses, results ranged from 25.36 pCi/liter to 29.23 pCi/liter. A fourth analysis was performed, with a result of 24.89 pCi/liter.

2.

Environmental Inc.'s MAPEP January 2006 vegetation Pu-238 result of 0.08 Bq/sample exceeded the lower control limit of 0.10 Bq/sample due to incomplete dissolution of the sample.

3.

Environmental Inc.'s MAPEP January 2006 air particulate Pu-238 result of 0.03 Bq/sample exceeded the lower control limit of 0.05 Bq/sample due to incomplete dissolution of the sample.

4.

Environmental Inc.'s MAPEP January 2006 soil Pu-238, Pu-239/240, U-233/234 and U-238 results of 14.6, 14.6, 13.5 and 15.4 Bq/kg, respectively, exceeded the lower control limits of 42.81, 32.09, 25.9 and 27.2 Bq/kg, respectively, due to incomplete dissolution of the sample.

In conclusion, the Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

For Cs-134, MAPEP suggests the Bi-214 is not being differentiated from the Cs-134 peak. See email attached with MAPEP results in Appendix A. NCR 06-07.

(3)

Sr samples analyzed in triplicate and one high result of 2.43 pCi/kg biased the submitted results on the high side.

We were unable to determine the cause for the higher result. Since we do not analyze vegetation for isotpic Pu, no NCR was initiated for the Pu failure. MAPEP suggest pyrosulfate fusion preparation prior to analysis for isotopic Pu in vegetation samples.

(4) Not detected, reported a statistically zero result. (False positive test)

(a) Teledyne Brown Engineering reported result.

(b) The MAPEP known value is equal to 100% of the parameter present in the standard as determined by gravimetric and/or volumetric measurements made during standard preparation.

(c) DOE/MAPEP evaluation: A=acceptable, W=acceptable with warning, N=not acceptable.

0 Summary and Conclusions This report on the Radiological Groundwater Protection Program (RGPP) conducted for the Oyster Creek Generating Station (OCGS) by AmerGen Energy Company covers the period 01 January 2006 through 31 December 2006.

In 2006, Exelon instituted a comprehensive program to evaluate the impact of station operations on groundwater and surface water in the vicinity of Oyster Creek Generating Station. This evaluation involved numerous station personnel and contractor support personnel.

This is the first in a series of annual reports on the status of the Radiological Groundwater Protection Program (RGPP) conducted at Oyster Creek Generating Station. This report covers groundwater and surface water samples collected from the environment, both on and off station property in 2006. At Oyster Creek Generating Station, 62 existing groundwater monitoring wells and three surface water locations were measured for ground water levels in early 2006. Following that, 252 analyses were performed on 86 samples from 44 locations. The monitoring was conducted in two phases. Phase 1 of the monitoring was part of a comprehensive study initiated by Exelon to determine whether groundwater or surface water at and in the vicinity of Oyster Creek Generating Station had been adversely impacted by any releases of radionuclides.

Phase 1 was conducted by Connestoga Rovers and Associates (CRA) and the conclusions were made available to state and federal regulators as well as the public on an Exelon web site:

http:/Iwww.exeloncorp.com/ourcompanies/powergen/nuclear/Tritium.htm.

Phase 2 of the RGPP was conducted by Exelon corporate and station personnel to begin long-term monitoring at groundwater and surface water locations selected during Phase 1. All analytical results from both the Phase 1 and Phase 2 monitoring are reported herein.

In assessing all the data gathered for this report, it was concluded that the operation of Oyster Creek Generating Station had no adverse radiological impact on the environment, and there are no known active releases into the groundwater at Oyster Creek Generating Station.

Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective Lower Limits of Detection (LLDs) as specified in the Offsite Dose Calculation Manual (ODCM) in any of the groundwater or surface water samples. In the case of tritium, Exelon specified that it's laboratories achieve a lower limit of detection 100 times lower than that required by federal regulation (200 pCi/liter versus 20,000 pCi/liter).

Strontium-89/90 was not detected in any of the groundwater or surface water samples tested.

Tritium was not detected in any of the groundwater or surface water samples at concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission Reporting Limit) of 20,000 pCi/liter. Tritium was detected in a single groundwater sample from a monitoring well onsite at an activity level of 211 +/- 115 pCi/liter, which is slightly above the LLD of 200 pCi/liter. This detection is consistent with low-level historical tritium detections in groundwater and is considered background.

II.

Introduction The Oyster Creek Generating Station (OCGS), consisting of one boiling water reactor owned and operated by AmerGen Energy Company, is located on the Atlantic Coastal Plain Physiographic Province in Ocean County, New Jersey, about 60 miles south of Newark, 9 miles south of Toms River, and 35 miles north of Atlantic City. It lies approximately 2 miles inland from Barnegat Bay. The site, covering approximately 781 acres, is situated partly in Lacey Township and, to a lesser extent, in Ocean Township. Access is provided by U.S. Route 9, passing through the site and separating a 637-acre eastern portion from the balance of the property west of the highway. The station is about 1/4 mile west of the highway and 1 1/4miles east of the Garden State Parkway. The site property extends about 21/2 miles inland from the bay; the maximum width in the north-south direction is almost 1 mile. The site location is part of the New Jersey shore area with its relatively flat topography and extensive freshwater and saltwater marshlands. The South Branch of Forked River runs across the northern side of the site and Oyster Creek partly borders the southern side.

This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Environmental Inc. (Midwest Labs) on samples collected in 2006.

A.

Objectives of the RGPP The long-term objectives of the RGPP are as follows:

1. Identify suitable locations to monitor and evaluate potential impacts from station operations before significant radiological impact to the environment and potential drinking water sources.

2. Understand the local hydrogeologic regime in the vicinity of the station and maintain up-to-date knowledge of flow patterns on the surface and shallow subsurface.

3. Perform routine water sampling and radiological analysis of water from selected locations.

4. Report new leaks, spills, or other detections with potential radiological significance to stakeholders in a timely manner.

5. Regularly assess analytical results to identify adverse trends.

6. Take necessary corrective actions to protect groundwater resources.

B.

Implementation of the Objectives The objectives identified have been implemented at Oyster Creek Generating Station as discussed below:

1.

Exelon and its consultant identified locations as described in the Phase 1 study. Phase 1 studies were conducted by Connestoga Rovers and Associates (CRA) and the results and conclusions were made available to state and federal regulators as well as the public on an Exelon web site in station specific reports.

http://www.exeloncorp.com/ourcompanies/powergen/nuclear/Tritiu m.htm

2.

The Oyster Creek Generating Station report describes the local hydrogeologic regime. Periodically, the flow patterns on the surface and shallow subsurface are updated based on ongoing measurements.

3.

Oyster Creek Generating Station will continue to perform routine sampling and radiological analysis of water from selected locations.

4.

Oyster Creek Generating Station has implemented new procedures to identify and report new leaks, spills, or other detections with potential radiological significance in a timely manner.

5.

Oyster Creek Generating Station staff and independent consults, including a hydrogeologist, assess analytical results on an ongoing basis to identify adverse trends.

C.

Program Description Samples for the OCGS RGPP Phase 1 were collected for AmerGen Energy Company by Connestoga Rovers and Associates (CRA) and samples for Phase 2 were collected by on-site personnel and Normandeau Associates, RMC Environmental Services Division (RMC).

This section describes the general collection methods used to obtain environmental samples for the OCGS RGPP in 2006. Sample locations can be found in Table A-I, Appendix A.

1.

Sample Collection Groundwater and Surface Water Samples of water are collected, managed, transported and analyzed in accordance with approved procedures following EPA methods. Both groundwater and surface water are collected.

Sample locations, sample collection frequencies and analytical frequencies are controlled in accordance with approved station procedures. Contractor and/or station personnel are trained in the collection, preservation management, and shipment of samples, as well as in documentation of sampling events. Analytical laboratories are subject to internal quality assurance programs, industry cross-check programs, as well as nuclear industry audits.

Station personnel review and evaluate all analytical data deliverables as data are received.

Analytical data results are reviewed by both station personnel and independent consultants, including a hydrogeologist for adverse trends or changes to hydrogeologic conditions.

D.

Characteristics of Tritium (H-3)

Tritium (chemical symbol H-3) is a radioactive isotope of hydrogen. The most common form of tritium is tritium oxide, which is also called "tritiated water." The chemical properties of tritium are essentially those of ordinary hydrogen.

Tritiated water behaves the same as ordinary water in both the environment and the body. Tritium can be taken into the body by drinking water, breathing air, eating food, or absorption through skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Tritium is excreted primarily through urine with a clearance rate characterized by an effective biological half-life of about 14 days. Within one month or so after ingestion, essentially all tritium is cleared. Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period. Tritium atoms can exchange with any hydrogen atom. If the hydrogen atom is part of an organic molecule, the tritium becomes 'organically bound' and is transported with the molecule rather than moving freely like water.

Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity, and in special production reactors, where the isotopes lithium-7 and/or boron-10 are activated to produce tritium. Also, tritium was released into the atmosphere from Chernobyl in 1986. Like normal water, tritiated water is colorless and odorless. Tritiated water behaves chemically and physically like non-tritiated water in the subsurface, and therefore tritiated water will travel at the same velocity as the average groundwater velocity.

Tritium has a half-life of approximately 12.3 years. It decays spontaneously to helium-3 (He-3). This radioactive decay releases a beta particle (low-energy electron). The radioactive decay of tritium is the source of the health risk from exposure to tritium. Tritium is one of the least dangerous radionuclides because it emits very weak radiation and leaves the body relatively quickly. Since tritium is almost always found as water, it goes directly into soft tissues and organs. The associated dose to these tissues is generally uniform and is dependent on the water content of the specific tissue.

Program Description A.

Sample Analysis This section describes the general analytical methodologies used by TBE and EIML to analyze the environmental samples for radioactivity for the Oyster Creek Generating Station RGPP in 2006.

In order to achieve the stated objectives, the current program includes the following analyses:

1.

Concentrations of gamma emitters in groundwater and surface water.

2.

Concentrations of strontium in groundwater and surface water.

3.

Concentrations of tritium in groundwater and surface water.

B.

Data Interpretation The radiological data collected prior to Oyster Creek Generating Station becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, Oyster Creek Generating Station was considered operational at initial criticality.

Several factors were important in the interpretation of the data:

1.

Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is defined as the smallest concentration of radioactive material in a sample that would yield a net count (above background) that would be detected with only a 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD is intended as a before the fact estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criterion for the presence of activity. All analyses were designed to achieve the required OCGS detection capabilities for environmental sample analysis.

The minimum detectable concentration (MDC) is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

2.

Laboratory. Measurements Uncertainty The estimated uncertainty in measurement of tritium in environmental samples is frequently on the order of 50% of the measurement value.

Statistically, the exact value of a measurement is expressed as a range with a stated level of confidence. The convention is to report results with a 95% level of confidence. The uncertainty comes from calibration standards, sample volume or weight measurements, sampling uncertainty and other factors. Exelon reports the uncertainty of a measurement created by statistical process (counting error) as well as all sources of error (Total Propagated Uncertainty or TPU). Each result has two values calculated.

Exelon reports the TPU by following the result with plus or minus

(+/-) the estimated sample standard deviation, as TPU, that is obtained by propagating all sources of analytical uncertainty in measurements.

Analytical uncertainties are reported at the 95% confidence level in this report for reporting consistency with the AREOR.

C.

Background Analysis A pre-operational radiological environmental monitoring program (pre-operational REMP) was conducted to establish background radioactivity levels prior to operation of the station. The environmental media sampled and analyzed during the pre-operational REMP were atmospheric radiation, fall-out, domestic water, surface water, marine life, and foodstuffs. The results of the monitoring were detailed in the report entitled, Pre-Operational Environmental Radiation Survey, Oyster Creek Nuclear Electric Generating Station, Jersey Central Power & Light Company, dated March 1968.

This report contains analytical results from samples collected from both surface water and groundwater.

Monthly surface water sampling began in 1966, and the samples were analyzed for tritium as well as other radioactivity. During the preoperational program, tritium was detected at an average concentration of 1.05E+3 pCi/liter, indicating that these preoperational results were from nuclear weapons testing and are radioactively decaying as predicted. At that time, counting instrumentation was not as sensitive as it is now, and the minimum detectable concentration was 1 E+3 pCi/liter versus 2E+2 pCi/liter used today. Gamma isotopic and radio strontium analyses results average concentrations were all greater than radioisotope analyses results from operational data.

1.

Background Concentrations of Tritium The purpose of the following discussion is to summarize background measurements of tritium in various media performed by others. Additional detail may be found by consulting references.

a.

Tritium Production Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., man-made) sources. In the upper atmosphere, "cosmogenic" tritium is produced from the bombardment of stable nuclides and combines with oxygen to form tritiated water, which will then enter the hydrologic cycle. Below ground, "lithogenic" tritium is produced by the bombardment of natural lithium present in crystalline rocks by neutrons produced by the radioactive decay of naturally abundant uranium and thorium. Lithogenic production of tritium is usually negligible compared to other sources due to the limited abundance of lithium in rock. The lithogenic tritium is introduced directly to groundwater.

A major anthropogenic source of tritium and strontium-90 comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium in precipitation increased significantly during the 1950s and early 1960s, and later with additional testing, resulting in the release of significant amounts of tritium to the atmosphere. The Canadian heavy water nuclear power reactors, other commercial power reactors, nuclear research and weapons production continue to influence tritium concentrations in the environment. Also, tritium was released into the atmosphere from Chernobyl, 1986.

b.

Precipitation Data Precipitation samples are routinely collected at stations around the world for the analysis of tritium and other radionuclides. Two publicly available databases that provide tritium concentrations in precipitation are Global Network of Isotopes in Precipitation (GNIP) and USEPA's RadNet database. GNIP provides tritium precipitation concentration data for samples collected world wide from 1960 to 2006.

RadNet provides tritium precipitation concentration data for samples collected at stations through out the U.S. from 1960 up to and including 2006. Based on GNIP data for sample stations located in the U.S. Midwest, tritium concentrations peaked around 1963. This peak, which approached 10,000 pCi/liter for some stations, coincided with the atmospheric testing of thermonuclear weapons. Tritium concentrations in surface water showed a sharp decline up until 1975 followed by a gradual decline since that time. Tritium concentrations in precipitation in New Jersey have typically been below 100 pCi/liter since around 1980. Tritium concentrations in wells may still be above the 200 pCi/liter detection limit from the external causes described above. Water from previous years and decades is naturally captured in groundwater, so some well water sources today are affected by the surface water from the 1960s that was elevated in tritium.

c.

Surface Water Data Tritium concentrations are routinely measured in large surface water bodies, including Forked River and Barnegat Bay. New Jersey surface water data were typically less than 100 pCi/liter.

The USEPA RadNet surface water data typically has a reported 'Combined Standard Uncertainty' of 35 to 50 pCi/liter. According to USEPA, this corresponds to a +/-70 to 100 pCi/liter 95% confidence bound on each given measurement. Therefore, the typical background data provided may be subject to measurement uncertainty of approximately +/- 70 to 100 pCi/liter.

The radio-analytical laboratory is counting tritium results to an Exelon specified LLD of 200 pCi/liter. Typically, the lowest positive measurement will be reported within a range of 40 - 240 pCi/liter or 140 +/- 100 pCi/liter. Clearly, these sample results cannot be distinguished as different from background at this concentration.

IV.

Results and Discussion Gamma spectroscopy results for each type of sample were grouped as follows:

For groundwater and surface water 11 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, Cs-134, Cs-137, Ba-140 and La-140 were reported.

A.

Groundwater Results Groundwater Samples were collected from on and off-site wells throughout the year in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.

TritUm Samples from 41 locations were analyzed for tritium activity (Table B-1.1 and B-1.2, Appendix B). Tritium was detected in a single groundwater sample from a monitoring well onsite at an activity level of 211 +/- 115 pCi/liter which is slightly above the LLD of 200 pCI/liter. This detection is consistent with low-level historical tritium detections in groundwater and is considered background.

Concentrations of tritium in shallow groundwater reached a maximum of 211 pCi/liter. Tritium concentrations ranged from 149 to 211 pCi/liter. Samples from the location most representative of potential offsite user of drinking water were all less than the LLD of 200 pCi/liter.

Concentrations detected were consistent with those detected in REMP samples.

Strontium No Sr-90 activity was detected in the 82 samples analyzed. (Table B-1.3 and B-1.4, Appendix B).

Gamma Emitters and Strontium Naturally occurring potassium-40 was detected in 15 of 84 samples. The concentrations ranged from 24 pCi/liter to 263 pCi/liter. No other gamma emitting nuclides were detected. (Table B-1.5 and B-1.6, Appendix B).

B.

Drinking Water Well Survey A drinking water well survey was conducted during the summer 2006 by CRA (CRA 2006) around the Oyster Creek Generating Station. CRA reviewed the New Jersey Geological Survey Bureau of Water Allocation Database Search included in the report entitled "Remedial Action Work Plan - Non-Radiological GPU Nuclear, Inc.; Oyster Creek Nuclear Generating Station U.S. Route 9 Forked River New Jersey" (URS GWC, 2000). The database provides a list of permitted wells within a 5-mile radius of the station and includes private, public, and industrial water supply wells and monitoring wells. The database indicates no public water supply well permits exist within a 0.5-mile radius of the center of the station (i.e., Reactor Building).

In addition to the two domestic water supply wells located on the OCGS site, the database indicated that there were three individually owned locations permitted for a water supply well within a 0.5-mile radius of the station.

In addition to the water supply wells identified in the database, there are seven wells located on the property to the west of the station (i.e.,

combustion turbine facility). These seven wells supply water for fire protection (4 wells), process water for the combustion turbine system (2 wells) and one domestic water supply well.

C.

Summary of Results - Inter-Laboratory Comparison Program Inter-Laboratory Comparison Program results for TBE and Environmental Inc. (Midwest Labs) are presented in the 2006 Oyster Creek AREOR.

D.

Leaks, Spills, and Releases The OCGS records inadvertent release of radioactive liquids in accordance with 10 CFR 50.75(g). As part of the fleet wide assessment, a third party environmental engineering firm was contracted to evaluate historic releases, if any, and determine if a potential pathway to the environment existed. Those releases that were determined to have potentially impacted groundwater were subsequently investigated as part of the fleet wide assessment.

The hydrogeologic investigation determined that there are currently no radiological impacts to groundwater at the Oyster Creek Generating Station.

E.

Trends No trends have been identified.

F.

Investigations Conclusions from the Phase 1 report have been made available to state and federal regulators as well as the public on an Exelon web site:

http://www.exeloncorp.com/ourcompanies/powergen/nuclear/Tritium.htm.

G.

Actions Taken

1. Compensatory Actions There have been no station events requiring compensatory actions at the Oyster Creek Generating Station.

2. Installation of Monitoring Wells No new wells were required to be installed.

3. Actions to Recover/Reverse Plumes There have been no station events requiring actions to recover/reverse any plumes.
