1. Summary and Conclusions This report on the Radiological Environmental Monitoring Program (REMP)conducted for the Oyster Creek Generating Station (OCGS) by Exelon Nuclear covers the period 01 January 2014 through 31 December 2014. During that time period, 1716 analyses were performed on 1248 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.

REMP designated surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides.

No tritium, fission or activation products were detected in any of the surface water samples collected as part of the Radiological Environmental Monitoring Program during 2014.REMP designated drinking water samples were analyzed for concentrations of gross beta, tritium, 1-131, and gamma emitting nuclides.

The preoperational environmental monitoring program did not include analysis of drinking water for gross beta. No tritium, 1-131, or fission or activation products were detected in any of the drinking water samples collected.

REMP designated groundwater samples were analyzed for concentrations of tritium and gamma emitting nuclides.

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

No OCGS-produced fission or activation products were detected in fish, clams or crabs. Cesium-137 was not detected in any sediment samples.Air particulate samples were analyzed for concentrations of gross beta, gamma emitting nuclides, Strontium-89, and Strontium-90.

Gross beta and cosmogenic Be-7 were detected at levels consistent with those detected in previous years.No fission or activation products were detected.

Strontium-89 and Strontium-90 analyses were performed on quarterly composites of air particulate samples. All Strontium-89 and Strontium-90 results were below the minimum detectable activity.High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable concentration.

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. No fission or activation products were detected.

All Strontium-89 results were below the minimum detectable activity.Strontium-90 activity was detected at levels consistent with those detected in previous years at both control and indicator stations, and can be attributed to historical nuclear weapons testing and the Chernobyl accident.1 Environmental gamma radiation measurements were performed quarterly using Optically Stimulated Luminescence Dosimeters (OSLD). Exelon changed the dosimetry used for environmental monitoring.

Beginning in calendar year 2012, Exelon began using OSLDs and discontinued the use of Thermo Luminescent Dosimetry (TLD). There were two main reasons for this change. First, OSLDs are not subject to "fade". Fade is where the dose on the dosimeter drifts lower over time. Second, OSLDs may be re-read if necessary.

TLDs are reset to zero after they are read. Levels detected were consistent with those observed in previous years. The maximum dose to any member of the public attributable to radioactive effluents and direct radiation from the OCGS was less than the 25 mrem/year limit established by the United Stated Environmental Protection Agency (EPA).2 II. Introduction The Oyster Creek Generating Station (OCGS), consisting of one boiling water reactor owned and operated by Exelon, 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 the 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 % mile west of the highway and 1 / 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 prior to the plant becoming operational in 1969. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Landauer and Environmental Inc. (Midwest Labs) on samples collected during the period 01 January 2014 through 31 December 2014.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).3 B. Implementation of the Objectives The implementation of the objectives is accomplished by: 1 .Identifying significant exposure pathways.2. Establishing baseline radiological data for 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, 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 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 4 environmental samples should include not only those nuclides expected to be released during facility operation, but should also 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 the people or the environment surrounding OCGS and is well below the applicable levels set by the Nuclear Regulatory Commission (NRC) and the EPA.5 There were liquid radioactive effluent releases during 2014 of concentrations of tritium too low to detect at an LLD of 200 picocuries per liter (pCi/L) at the New Jersey Pollution Discharge Elimination System (NJPDES) permitted main condenser outfall.The releases were part of nearly continuous pumping of groundwater at approximately 70 gpm containing low levels of tritium and no detectable gamma. Exelon and the State of New Jersey Department of Environmental Protection (NJDEP) agreed to this remediation action instead of natural attenuation to address concentrations of tritium in groundwater.

Well 73 and supporting equipment and piping were installed to pump groundwater to the intake structure at the inlet of the main circulating water pumps.Provisions were established for both batch and continuous releases of groundwater.

Continuous releases occurred approximately 230 days in 2014. The nearly continuous releases occurred from March 12, 2014 through December 31, 2014 with a total of 2.31 E+07 gallons of groundwater pumped resulting in 1.74E-01 Ci of tritium released to the discharge canal. The dose to the most limiting member of the public due to the release of groundwater was 8.28E-07 mrem.Utilizing gaseous effluent data, the maximum hypothetical dose to any individual during 2014 was calculated using a mathematical model, which is based on the methods defined by the U.S. Nuclear Regulatory Commission.

These methods accurately determine the types and quantities of radioactive materials being released to the environment.

The maximum calculated organ dose (Bone) from iodines, tritium, carbon-14 (C-14), and particulates to any individual due to gaseous effluents was 4.78E-01 mrem, which was approximately 3.19E+00 percent of the annual limit of 15 mrem. The maximum calculated gamma air dose in the UNRESTRICTED AREA due to noble gas effluents was 1.62E-02 mrad, which was 1.62E-01 percent of the annual 10 CFR 50 Appendix I, As Low As Reasonably Acheivable (ALARA) limit of 10mrad. The majority of organ dose from gaseous effluents was due to C-14. The maximum hypothetical calculated whole body dose to any individual due to noble gas effluents was 2.18E-03 mrem (0.00218 mrem) which was 4.36E-02 percent of the annual limit of 5 mrem.The total maximum organ dose (Bone) due to all radiological effluents of 4.94E-01 mrem (0.494 mrem) received by any individual from gaseous effluents from the Oyster CreekGenerating Station for the reporting period is more than 607 times lower than 6 the dose the average individual in the Oyster Creek area during the same time period. The background radiation dose averages approximately 300 mrem per year in the Central New Jersey area, which includes approximately 200 mrem/year from naturally occurring radon gas.During 2014, the maximum direct radiation dose to the most likely exposed MEMBER OF THE PUBLIC potentially attributable to the operation of Oyster Creek beyond the site boundary in the west sector, as shown by offsite OSLD readings at station 55 was 5.09 mrem. The nearest member of the public is considered a part-time resident that works 2,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> per year at a warehouse located west of the plant.Environmental sampling of airborne iodine and particulates showed no radioactivity attributable to the operation of OCGS.Ill. Program Description A. Sample Collection Samples for the OCGS REMP were collected for Exelon by on-site personnel and Normandeau Associates, Incorporated.

This section describes the general collection methods used to obtain environmental samples for the OCGS REMP in 2014. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-1, B-2, and B-3, 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, drinking water, groundwater, 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), monthly from six drinking water wells (1 N, 1S, 37, 38, 39, and 114) and quarterly from 2 groundwater stations (MW-24-3A and W-3C). 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)).

Two annual crab samples were collected from two locations (33 and 93). Sediment samples were collected at four locations semiannually (23, 24, 33, and 94 (control)).

7 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 eight locations (C, 3, 20, 66, 71, 72, 73, and 111). 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 four locations (35, 36, 66, and 115). 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 A1 2 0 3:C Optically Stimulated Luminescence Dosimetry (OSLD). Exelon changed the dosimetry used for environmental monitoring.

Beginning in calendar year 2012, Exelon began using OSLDs and discontinued the use of Thermoluminescent Dosimetry (TLD). There were two main reasons for this change. First, OSLDs are not subject to "fade". Fade is where the dose on the dosimeter drifts lower over time. Second, OSLDs may be re-read if necessary.

TLDs are reset to zero after they are read. The OSLDs were placed on and around the OCGS site and were categorized as follows: An inner ring consisting of 19 locations (1, T1, 51, 52, 53, 54, 55, 56, 57, 58, 59, 61, 62, 63, 64, 65, 66, 112, and 113) near the site boundary.An outer rinq consisting of 31 locations (4, 5, 6, 8, 9, 22, 46, 47, 48, 68, 73, 74, 75, 78, 79, 82, 84, 85, 86, 98, 99,100,101,102,103,104,105, 106, 107, 109, and 110) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.

8 Special interest stations consisting of 9 locations (3, 11, 71, 72, 81, 88, 89, 90, and 92) representing special interest areas such as population centers, state parks, etc.Background (Control) stations consisting of two locations (C and 14)greater than 20 miles distant from the site.Indicator OSLDs were placed systematically, with at least one station in each of 16 meteorological compass sectors in the general area of the site boundary.

OSLDs were also placed in each meteorological sector in the 1 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 OSLDs were placed at each location approximately three to eight feet above ground level. The OSLDs were exchanged quarterly and sent to Landauer 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 2014. 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 and drinking water.2. Concentrations of gamma emitters in surface, drinking water, groundwater, fish, clams, crabs, sediment, air particulates and vegetation.

3. Concentrations of tritium in REMP designated surface, drinking water and groundwater.

4. Concentrations of 1-131 in air iodine cartridges and drinking water.5. Concentrations of strontium in air particulates and vegetation.

6. Ambient gamma radiation levels at various locations around the 9 OCGS.C. Data Interpretation For trending purposes, the radiological and direct radiation data collected during 2014 were compared with data from past years. The results of environmental sampling show that radioactivity levels have not increased 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 Reportingq 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, drinking water, and groundwater

-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.10 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.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-1 34, and Cs-1 37 were reported.For air iodine cartridges

-one nuclide: 1-131 was reported.For vegetation

-seven nuclides:

Be-7, K-40, 1-131, Cs-1 34, 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 2014 the OCGS REMP had a sample recovery rate in excess of 99%.Exceptions are listed below: Drinking Water 1. Station 39 (Lacey Twp., MUA Pump Station) was not collected January 1, 2014 through December 31, 2014. The station was off line for this time period.2.

In addition, grab samples were 12 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). No tritium activity was detected.

Data from this year indicates that surface water tritium concentrations remain very low and not significantly different from recent previous years.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 pCi/liter versus 2E+2 pCi/liter used today. By comparing the 2014 sampling results to the decay corrected average preoperational concentration reported in the 2007 Annual Radiological Environmental Operating Report (1.11 E+2 pCi/liter), 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. Drinking water Monthly samples were composited from monthly grab samples from six drinking water wells (1N, 1S, 37, 38, 39, and 114). Station 1, because it is located on the OCGS site, could potentially be affected by radioactive releases from the plant. Station 1 was split into two separate locations, 1N and 1S. Station 38, the Ocean Township Municipal Utility Authority Well, could potentially be affected by effluent releases from the OCGS. Given its distance from the facility (1.6 miles) and depth (approximately 360 feet), however, the probability of any OCGS related impacts is very small.Stations 37 and 39, Lacey Township Municipal Utility Authority wells, are not likely to be impacted by effluents from the OCGS.These wells are located generally up-gradient of the regional 13 groundwater flow direction (southeast).

In addition, because of their depth (> 200 feet) and distance from the site (2.2 and 3.5 miles respectively), they are unlikely to be affected by OCGS operations.

The following analyses were performed:

Tritium Monthly samples from all locations were analyzed for tritium activity (Table C-11.1, Appendix C). No tritium activity was detected.Drinking water was sampled during the preoperational program and throughout the 43 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.

2014 results are all less than the current MDC of 2E+2 pCi/liter.

Gross Beta Monthly samples from all locations were analyzed for concentrations of total gross beta activity (Tables C-11.2, Appendix C). Gross beta was detected in 41 of 51 samples, and is expected due to natural sources and fallout residual from previous bomb testing. The values ranged from 1.8 to 21.1 pCi/I.The investigation level for gross beta in water is 15 pCi/I. Drinking water sample 1 N result for gross beta exceeded the investigation level beginning in January 2012.The initial result for gross beta was 15.1 pCi/I in 2012. This issue was entered into our Corrective Action Program (CAP) and an investigation initiated.

The 1 N water sample was analyzed for known beta emitters Sr-89, Sr-90, Fe-55 and Ni-63. These analyses results were all <MDC. It was also identified that the 1 N well treatment system was upgraded the previous month and a potassium chloride softener system was added as part of the upgrade. Samples were obtained pre and post treatment.

The pre-treatment result for gross beta was 3.6 pCi/I, which is a value that has been seen previously in drinking water samples. The post-treatment sample result for gross beta was 22.2 pCi/I.Based on the fact that there were no typical plant produced beta emitters detected and that natural potassium is a known beta emitter along with the results of the pre and post sampling, the gross beta values obtained for 1 N can be attributed to the addition of the water softener system installed during the system upgrade in December of 2011.14 Iodine Monthly samples from all locations were analyzed for 1-131 by the low level method to detect down to 1 pCi/L (Table C-11.3, Appendix C). All results were less than the MDC.Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-11.4, Appendix C). All nuclides were less than the MDC.3. Groundwater The following analyses were performed:

Tritium Samples from all locations were analyzed for tritium activity (Table C-I11.1, Appendix C). No tritium activity was detected.Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-111.2, Appendix C). All nuclides were less than the MDC.4. Fish Fish samples comprised of bottom feeder (silver perch, white perch, and summer flounder) and predator (American Eel, striped bass, and bluefish) 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-IV.1, Appendix C).Naturally occurring potassium-40 was found at all stations and ranged from 3,219 to 5,340 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.15 No fish were sampled during the preoperational sampling program for OCGS.5. Clams and Crabs Clams were collected at three locations (23, 24, and 94)semiannually.

Crabs were collected at two locations (33 and 93)annually.

Locations 23, 24, 33, 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-IV.2, Appendix C).Naturally occurring potassium-40 was found at all stations and ranged from 1,235 to 1,944 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 naturally occurring Potassium-40 ranged from 600 to 9,800 pCi/kg wet, which are consistent with current sample results.The edible portions of crab samples from two locations were analyzed for gamma emitting nuclides (Table C-IV.2, Appendix C).Naturally occurring potassium-40 was found at both stations and ranged from 1,950 to 2,186 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.6. 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-V.1, Appendix C). Naturally occurring 16 Potassium-40 was found at all stations and ranged from 783 to 14,800 pCi/kg dry. Cesium-137 was not detected in any of the samples. No fission or activation products were found. Figure C-3, Appendix C graphs Cs-1 37 concentrations in sediment from 1984 through 2014 and figure C-2, Appendix C graphs Co-60 concentrations in sediment from 1984 through 2014.The requirement for sampling sediment is a requirement of ODCM 3.12.1, Table 3.12.1-1.d.

ODCM Table 3.12.1-2, Reporting Levels for Radioactive Concentrations in Environmental samples Reporting Levels does not include requirements for sediment.CY-AA-170-1000, Radiological Environmental Monitoring Program and Meteorological Program Implementation, Attachment 1, Analytical Results Investigation Levels, includes sediment investigation level for Cs-1 37 of 1000 pCi/kg, dry.While aquatic sediment sampling was part of the preoperational program, samples were not analyzed for gamma emitting nuclides until 1981.In conclusion, the 2014 aquatic monitoring results for surface water, drinking water, fish, clams and crabs showed only naturally occurring radioactivity 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 2014 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 eight locations on a weekly basis. The eight locations were separated into three groups: Group I represents locations near the OCGS site boundary (20, 66 and 111), 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:

17 Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Table C-VI.1 and C-VI.2, Appendix C).Detectable gross beta activity was observed at all locations.

Comparison of results among the three groups aids 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 39 E-3 pCi/m 3 with a mean of 14 E-3 pCi/m 3.The results from the Intermediate Distance locations (Group II) ranged from 6 to 34 E-3 pCi/m 3 with a mean of 14 E-3 pCi/m 3.The results from the Distant locations (Group Ill) ranged from 6 to 27 E-3 pCi/m 3 with a mean of 13 E-3 pCi/m 3.The similarity of the results from the three groups indicates that there is no relationship between gross beta activity and distance from OCGS. These results are consistent with data from previous years and indicate no effects from the operation of OCGS (Figures C-4 and C-5, Appendix C).Air sample filters have been analyzed for gross beta activity since the inception of the preoperational environmental monitoring program in 1966. The preoperational data values ranged from 1.90E-2 to 2.77E-1 pCi/m3. 2014 gross beta activity values ranged from <6E-3 to 39E-3 pCi/m3. The 2014 results are consistent with historical operational data (Figure C-5, Appendix C) and fall within the range of results observed during the preoperational period.Strontium-89 and Strontium-90 Weekly samples were composited quarterly and analyzed for strontium-89 and strontium-90 (Table C-VI.3, Appendix C). No strontium was detected in any of the samples. These results are consistent with historical operational data. The preoperational environmental monitoring program did not include analysis of air samples for strontium-89 and strontium-90.

Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C-VI.4, Appendix C).Naturally occurring Be-7 due to cosmic ray activity was detected in all samples. The values ranged from 35 to 106 18 E-3 pCi/m 3.All other nuclides were less than the MDC.These results are consistent with historical operational data.The preoperational environmental monitoring program did not include analysis of air samples for gamma emitting nuclides.b. Airborne Iodine Continuous air samples were collected from eight (C, 3, 20, 66, 71, 72, 73, 111) locations and analyzed weekly for 1-131 (Table C-VII.1, Appendix C). Consistent with historical operational data, all results were less than the MDC for 1-131.The preoperational environmental monitoring program for OCGS did not include analysis of air media for iodine-1 31.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 four locations (35, 36, 66, and 115) 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-VIII.1, Appendix C). All strontium-89 results were less than the MDC. Strontium-90 was detected in 24 of 60 samples.The values ranged from 1.3 to 9.5 pCi/kg wet, which is consistent with historical data.The following information on Strontium 90 is available on the NRC web page under "Backgrounder Radiation Protection and the "Tooth Fairy" Issue" published in December of 2004.The largest source of Sr-90 in the environment

(,-, 9 9%) is from weapons testing fallout. Approximately 16.8 million 19 curies of strontium-90 were produced and globally dispersed in atmospheric nuclear weapons testing until 1980. As a result of the Chernobyl accident, approximately 216,000 curies of Sr-90 were released into the atmosphere.

With a 28 year half-life, Sr-90 still remains in the environment at nominal levels.The total annual release of strontium-90 into the atmosphere from all 103 commercial nuclear power plants operating in the United States is typically 1/1000th of a curie. (NUREG/CR-2907 Vol.12). At an individual nuclear power plant, the amount of Sr-90 is so low that it is usually at or below the minimum detectable activity of sensitive detection equipment.

Oyster Creek did not report any Sr-90 released in the Annual Radioactive Effluent Release Report as all analyses for Sr-90 performed were less than the minimum detectable activity.Gamma Spectrometry Vegetation samples from locations 35, 36, 66, and 115 were analyzed for concentrations of gamma emitting nuclides (Table C-VIII.1, Appendix C). Naturally occurring K-40 activity was found in all samples and ranged from 2,313 to 10,020 pCi/kg wet. Naturally occurring Be-7 was detected in 18 of 60 samples and ranged from 105 to 1,982 pCi/kg wet.All other nuclides were less than the MDC.Preoperational vegetation sample analyses did not include strontium analyses or gamma spectroscopy.

Oyster Creek conducted a Cs-1 37 study in 2006/2007.

A report was generated titled "Evaluation of Cesium-1 37 in Environmental Samples from the Amergen Property East of the Oyster Creek Generating Station".

Below is an excerpt from that report: The levels of Cs-1 37 observed in the soil and vegetation samples are consistent with environmental concentrations known to be attributable to fallout from historic nuclear weapons testing and the Chernobyl accident.

In addition, the variability of Cs-1 37 concentrations in soil and vegetation on the farm property appears to be driven by a number of environmental factors. Cs-137 concentrations in soil were non-detectable.

Vegetation samples exhibited Cs-137 20 concentrations from non-detectable to 0.130 pCi/g, with a mean concentration of 0.078 pCi/g. For comparison, in the year 2000, as part of the confirmatory release survey for the adjacent Forked River site to the west of OCGS, the NRC reported that the maximum observed soil concentration of 0.53 pCi/g was not distinguishable from the variation in Cs-137 in the environment due to these fallout sources. The NRC also reported background Cs-1 37 concentrations in New Jersey coastal plain soils as high as 1.5 and 2.8 pCi/g.In addition, decay-corrected historic REMP data from a predominantly upwind location, nearly four miles from the OCGS, yields present-day Cs-1 37 concentrations ranging from 0.862 to 1.68 pCi/g.There was no Cs-1 37 identified in REMP soil and vegetation samples in 2014, but it is not unusual for Cs-1 37 to be identified given the known environmental levels of this radionuclide attributable to atmospheric nuclear weapons testing and the Chernobyl accident.In conclusion, terrestrial monitoring results for vegetation samples during 2014 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 using Optically Stimulated Luminenscence Dosimeters (OSLD). Sixty-one OSLD locations were monitored around the site. Results of non-background corrected OSLD measurements are summarized in Tables C-IX.1 to C-IX.3 and Figures C-6 and C-7.The non-background corrected OSLD measurements ranged from 4.9 to 16.0 mR/standard quarter. In order to correct these results for background radiation, the mean of the dose rates measured at the background OSLD stations (C and 14) was subtracted from the dose measured at each indicator station. The maximum annual background corrected dose was 22.3 mR/year at Station 55, located near the site boundary, 0.3 miles west of the OCGS. This OSLD is located in an area where public access is 21 restricted but the nearest member of the public for direct radiation is considered an individual that works in the warehouse west of the site.The individual is assumed to work 2,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> per year at this location.The preoperational environmental monitoring program utilized film badges, the results of which are not comparable with the doses measured using thermoluminescent dosimeters or optically stimulated dosimeters during the operational REMP. In conclusion, the 2014 OSLD results are consistent with past operational measurements of direct radiation, and demonstrate that the OCGS continues to be in compliance with the 40 CFR 190 limit on maximum dose to the public.D. Land Use Survey A Land Use Survey, conducted in August 2014 around the Oyster Creek Generating Station (OCGS), was performed by Normandeau Associates, Inc. for Exelon Nuclear. The purpose of the survey is to identify within a distance of 5 miles the location in each of the 16 meteorological sectors of the nearest milk animal, the nearest residence and the nearest garden of greater than 500 ft2 producing broad leaf vegetation.

The census shall also identify within a distance of 3 miles the location in each of the 16 meteorological sectors all milk animal and all gardens greater than 500 square feet producing broadleaf vegetation.

For 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.

The distance and direction of all locations from the OCGS Reactor Building were determined using Global Positioning System (GPS) technology.

There were no changes required to the OCGS REMP, as a result of this survey. The results of this survey are summarized below.22 Distance in Feet from the OCGS Reactor Building Sector Residence Garden*(ft) (ft)1 N 5,655 8,224 2 NNE 3,240 3,541 3 NE 3,245 5,115 4 ENE 5,704 6,445 5 E 6,549 1,758 6 ESE 3,189 2,081 7 SE 3,073 2,321 8 SSE 4,666 8,341 9 S 7,971 9,011 10 SSW 8,344 20,130 11 SW 9,285 9,776 12 WSW 10,713 14,802 13 W 22,191 None 14 WNW None None 15 NW 27,985 None 16 NNW 7,506 14,487*Greater than 500 ft2 in size producing broad leaf vegetation E. 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 F). 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: 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, the National Environmental Laboratory Accreditation Conference (NELAC), state specific performance testing (PT) program requirements or ERA's SOP for 23 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.

In reviewing our environmental inter-laboratory crosscheck programs, we identified

1) duplication of efforts on some matrices and isotopes and 2)that we are performing crosscheck samples on some matrices and isotopes that we do not perform for clients. Since the DOE MAPEP is designed to evaluate the ability of analytical facilities to correctly analyze for radiological constituents representative of those at DOE sites, the needed changes were made to the MAPEP program. Therefore, the following isotopes were removed from the MAPEP program: Soil -gamma -will be provided by Analytics twice per year, starting in 2015. For 2014, one soil gamma is provided by MAPEP, the 2nd soil gamma is provided by Analytics.

AP -gamma -is currently provided by Analytics.

Water -gamma, H-3, Sr-90, uranium, gross alpha and gross beta currently provided by ERA.MAPEP evaluates non-reported (NR) analyses as failed if they were reported in the previous series.For the TBE laboratory, 163 out of 169 analyses performed met the specified acceptance criteria.

Six analyses (Ni-63, K-40 and 1-131 in water, and two Sr-90s and one Gross Alpha in AP samples) did not meet the specified acceptance criteria for the following reasons: 1. Teledyne Brown Engineering's MAPEP March 2014 Ni-63 in water result of 32.7 +/- 1.69 Bq/L was overlooked when reporting the data 24 but would have passed the acceptance range of 23.9 -44.2 Bq/L.NCR 14-04 2. Teledyne Brown Engineering's MAPEP March 2014 K-40 in water result of 1.63 +/- 2.49 Bq/L was overlooked when reporting the data but would have passed the false positive test. NCR 14-04 3. Teledyne Brown Engineering's ERA November 2014 1-131 in water result of 15.8 pCi/L was lower than the known value of 20.3 pCi/L, falling below the lower acceptance limit of 16.8. The result was evaluated as failed with a found to known ratio of 0.778. No cause could be found for the slightly low result. All previous ERA 1-131 evaluations since 2004 have been acceptable.

NCR 14-08 4. Teledyne Brown Engineering's MAPEP March 2014 Sr-90 in AP result of 0.822 Bq/sample was lower than the known value of 1.18 Bq/sample, failing below the lower acceptance limit of 0.83 Bq/sample.

The reanalysis result was still low, but fell within the lower acceptance range of 0.836. The reanalysis result was statistically the same number as the original result. No cause could be found for the slightly low results. NCR 14-04 5. Teledyne Brown Engineering's MAPEP September 2014 Sr-90 in AP result of 0.310 Bq/sample was lower than the known value of 0.703 Bq/sample.

The gravimetric yield of 117% was very high (we normally see yields of 60% to 70%) and could account for the low activity.

The reanalysis result of 0.508 was still low, but fell within the lower acceptance range of 0.492. No cause could be found for the slightly low results. NCR 14-09 6. Teledyne Brown Engineering's MAPEP September 2014 Gr-Alpha in AP result of 0.153 Bq/sample was lower than the known value of 0.53 Bq/sample.

The AP sample was counted on the wrong side.The AP was flipped over and recounted with acceptable results.TBE does not perform the gross alpha analysis in support of REMP programs.

All effluent AP samples are digested and analyzed as a portion of the total volume (typically 10%). In conclusion, this error could not be duplicated on client effluent APs, because the MAPEP AP is counted as a whole and the client effluent AP sample is digested.

TBE routinely performs Analytics AP gross alpha blind sample analysis with no issues. NCR 14-09 For the EIML laboratory, 85 of 90 analyses met the specified acceptance criteria.

Five analyses (Water -Pu-238, Pu-239, Fe-55; AP -Co-57; Soil-Cs1 34) did not meet the specified acceptance criteria for the following reasons: 25

1. Environmental Inc., Midwest Laboratory's MAPEP February 2014 water Pu-238 result of 1.28 Bq/L was higher than the known value of 0.83 Bq/L, exceeding the upper control limit of 1.08 Bq/L. The high bias on the plutonium was traced to contamination from a newly purchased standard.

The result of the reanalysis with the new tracer was 0.68, which fell within the acceptance criteria.2. Environmental Inc., Midwest Laboratory's MAPEP February 2014 water Pu-239/240 result of 0.91 Bq/L was higher than the known value of 0.68 Bq/L, exceeding the upper control limit of 0.88 Bq/L.The high bias on the plutonium was traced to contamination from a newly purchased standard.

The result of reanalysis with the new tracer was 0.66 Bq/L, which fell within the acceptance criteria.3. Environmental Inc., Midwest Laboratory's MAPEP February 2014 AP Co-57 result of 1.60 +/- 0.05 Bq/total sample failed the false positive test. Interference from the Eu-152 resulted in the misidentification of Co-57.4. Environmental Inc., Midwest Laboratory's MAPEP February 2014 soil Cs-1 34 result of 6.10 +/- 1.80 Bq/kg failed the false positive test.Long sample counting time lead to interference from naturally occurring Bi-214 in the sample matrix with a close spectral energy.5. Environmental Inc., Midwest Laboratory's MAPEP August 2014 water Fe-55 result of 55.10 +/- 14.80 Bq/L was higher than the known value of 31.50 Bq/L, exceeding the upper control limit of 41.00 Bq/L. The result of the reanalysis of Fe-55 was 32.63 +16.30 Bq/L, which fell within the acceptance criteria.V. References 1 .Exelon Nuclear.

MAPEP results are presented as the known values and expected laboratory precision (1 sigma, 1 determination) and control limits as defined by the MAPEP. A known value of "zero" indicates an analysis was included in the testing series as a "false positive".

MAPEP does not provide control limits.(1) The high bias on the plutonium crosscheck samples was traced to contamination from a newly purchased standard.The results of reanalysis with replacement tracer purchased from NIST: MAW-1184 Pu-238 0.68 +/- 0.10 Bq / L MAW-1184 Pu-239/240 0.66 + 0.10 Bq / L (2) Interference from Eu-1 52 resulted in misidentification of Co-57.(3) Provided in the series for "sensitivity evaluation".

MAPEP does not provide control limits.(4) False positive test. Long sample counting time lead to interference from naturally occuring Bi-214 in sample matrix with a close spectral energy.(5) Result of reanalysis Fe-55 32.63 +/- 16.30 Bq/L E-9 APPENDIX F ERRATA DATA Corrections to the 2012 AREOR The value for direct radiation at station 113 for the second quarter is listed in the report as 0.0 millirem/standard quarter since the dosimeters were attached to a telephone pole that was removed due to road construction.

The value of 0.0 millirem/standard quarter is correct, the error is that the 0.0 millirem/standard quarter value was used to determine the mean values in the following areas of the report: F-I Docket No: 50-219 OYSTER CREEK GENERATING STATION UNIT 1 Annual Radiological Environmental Operating Report 1 January Through 31 December 2012 Prepared By Teledyne Brown Engineering Environmental Services~ Exelon Generation, Oyster Creek Generating Station Forked River, NJ 08731 April 2013 F-2 Original Page -Oyster Creek 2012 Annual Radiological Environmental Operating Report TABLE A-i RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM ANNUAL

In 2014, 1,275 analyses were performed on 498 samples from 63 locations.

There were three inadvertent releases of contaminated water into the groundwater during 2009. There is a plume located west of the turbine building and is monitored via a series of monitoring wells.Gamma-emitting radionuclide K-40 was detected in nine of the 54 groundwater well samples. The concentrations ranged from 35 to 248 pCi/L. Potassium-40 was detected in 264 of 266 surface water samples. The concentrations ranged from 89 to 580 pCi/L.In the case of tritium, Exelon specified that its laboratories achieve a lower limit of detection 100 times lower than the drinking water limit specified by the United States Environmental Protection Agency (USEPA) (200 pCi/I versus 20,000 pCi/I).As expected, tritium was detected in groundwater samples. The 2014 Tritium concentrations varied from <200 to 26,835 pCi/I. The well with the highest concentration was MW-561. The flow of groundwater is in the direction of the intake and discharge canals.No detectable tritium (greater than the MDC) was found in surface water or precipitation samples collected from onsite and offsite monitoring locations during 2014.Strontium-89 and strontium-90 were not detected in any groundwater samples during 2014.Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the second quarter sampling in 2014.There were 48 samples taken from 43 groundwater well locations.

Gross Alpha (dissolved) was detected in 11 samples and ranged from 0.4 to 4.7 pCi/L. Gross Alpha (suspended) was detected in 20 samples and ranged from 1.4 to 29.1 pCi/L. Gross Beta (dissolved) was detected in 41 samples and ranged from 1.6 to 29.4 pCi/L. Gross Beta (suspended) was detected in 22 samples and ranged from 1.8 to 215 pCi/L."Hard-To-Detect" analyses were performed on a select group of groundwater locations.

The analyses for groundwater included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-234, U-235, and U-238. U-234 and U-238 were detected in three of eight samples. The concentrations of U-234 and U-238 ranged from 0.27 to 0.81 pCi/L and 0.13 to 1.30 pCi/L, respectively.

All other Hard-To-Detect analyses were less than the MDC.Occasionally the isotopes of U-234 and U-238 are detected and are considered background.

II. Introduction The Oyster Creek Nuclear Generating Station consists of a single boiling water reactor (BWR) and turbine generator capable of producing 650 megawatts of electricity.

The Station operates under Nuclear Regulatory Commission (NRC)renewed facility operating license number DPR-16. Brackish water from Barnegat Bay is supplied to the circulating water system. The circulating water system is designed to supply a continuous flow of water from Barnegat Bay through the plant to remove the waste heat released by the power cycle in the Main Condenser.

The circulating water system is comprised of the intake canal from Barnegat Bay to the plant, the Main Condenser Circulating Water System, the dilution plant, and the discharge canal to Barnegat Bay. The dilution plant portion of the system minimizes the adverse effects of hot discharge water on aquatic life in the discharge canal and Barnegat Bay to meet the conditions of the Oyster Creek New Jersey Pollutant Discharge Elimination system (NJPDES)Permit No. NJ0005550.

Approximately 1 million gallons per minute of water are withdrawn from the intake canal for dilution and station use and returned to the discharge canal.The Station is located in the Atlantic Coastal Plain physiographic province.Topography in the region of the Station is a slightly undulating coastal plain having low relief. The land surface gradually rises from sea level at Barnegat Bay, which is located east of the Station, to approximately 50 feet above mean sea level (AMSL) 2 miles inland. This region of the coastal plain has numerous tidal marshes and is incised by easterly flowing streams and creeks. Elevations at the Station property west of Route 9 range from approximately 0 to 15 feet AMSL immediately adjacent to the intake and discharge canals to slightly more than 30 feet AMSL in the northwest portion of the Station property.

The 132-acre developed portion of the Site located within the "horseshoe" formed by the intake and discharge canals west of Route 9 has an approximate average elevation of 20 feet AMSL. In the immediate vicinity of the intake and discharge canals, the Station property slopes steeply down to the canal. The average elevation of the surface water level in the intake and discharge canals is approximately 1-foot AMSL. The remaining 637-acre portion of the Station located east of Route 9 is primarily vegetated and undeveloped.

The ground surface is relatively level except for the steep slopes at areas adjacent to the intake and discharge canals.The three shallowest stratigraphic units in the vicinity of the Oyster Creek area in descending order are the Cape May Formation, the Cohansey Formation, and the Kirkwood Formation.

Some of the Station structures are constructed to depths of approximately 50 feet below ground surface (bgs). Excavations were completed from grade, through the fill, Cape May Formation, Upper Clay, and into the Cohansey Formation during construction.

Consequently, the bottoms of some Station structures are completed within the Cohansey Formation and some structures breach the Upper Clay.The Cape May Formation regionally has an average thickness of 40 feet and at OCGS, the Cape May is described as a light gray to tan, medium- to fine-grained sand, with trace to some silt and occasional coarse sand. It is generally poorly compacted.

The Cape May Formation varies from 0 to 21 feet in thickness based on historical boring logs. The variation principally is due to the varying amount of material excavated and replaced by fill during Station construction.

When present, the thickness of the Cape May generally ranges from 15 to 20 feet thick. The base of the Cape May generally is defined by the presence of a dark clay unit referred to as the Upper Clay unit. The Upper Clay is a stiff to hard, gray, plastic organic clay containing inclusions (also described as lenses or partings) of dense fine sand with trace to some organic silt. The deposits of fine sand within the Upper Clay layer have high relative densities and occur as lenses or inclusions.

The Cohansey Formation is primarily composed of a light-colored, fine- to very coarse-grained quartzose sand with lenses of silt and clay. Although most borings at the Station do not penetrate the entire Cohansey Formation, this formation appears to be approximately 60 to 80 feet thick at OCGS. A clay sequence, referred to at the Station as the "Lower Clay", marks the base of the Cohansey, which generally is present to approximately 90 to 100 feet bgs. The lower clay is a dense gray medium- to fine-grained sand containing trace to some organic silt and layers or inclusions of very stiff to hard gray organic clay.The thickness of the lower clay is estimated to be approximately 10 to 20 feet in the vicinity of OCGS.The Cohansey Formation is underlain by the Kirkwood Formation which consists of several stratigraphic units. The Kirkwood Formation is described as a medium- to fine-grained sand with trace silt. The thickness of this formation beneath the Station is unknown. The south domestic supply well terminates in the Kirkwood at a depth of 310 feet bgs. The Kirkwood thickness in Ocean County ranges from approximately 300 to 400 feet.This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Environmental Inc. (Midwest Labs) on samples collected in 2014.A. Objectives of the RGPP The long-term objectives of the RGPP are as follows:* Ensure that the site characterization of geology and hydrology provides an understanding of predominant ground water gradients based upon current site conditions.

" Identify site risk based on plant design and work practices." Evaluate all SSCs that contain or could contain licensed material and for which there is a credible mechanism for the licensed material to reach groundwater." Evaluate work practices that involve licensed material and for which there is a credible mechanism for the licensed material to reach groundwater." Perform on-site monitoring to ensure timely detection of inadvertent radiological releases to ground water." Understand background concentrations of radioactive analytes outside of the REMP, as required." Evaluate return/re-use of previously discharged radioactive effluents in gaseous or liquid effluents that are returned from the environment to the operating nuclear power facility." Ensure controls are established for the selection, installation and retirement of monitoring wells." Perform remediation protocols to prevent migration of licensed material off-site and to minimize decommissioning impacts." Ensure that records of leaks, spills, remediation efforts are retained and retrievable to meet the requirements of 10 CFR 50.75(g)." Ensure periodic communications are held on the RGPP with the designated State/Local officials." Ensure timely verbal and written reporting occurs if there is an inadvertent release of licensed materials to the soil, groundwater or surface water." Document and report all applicable RGPP data." Identify and resolve deficiencies via the Corrective Action Process as delineated in PI-AA-120 "Issue Identification and Screening Process"." Perform program oversight to ensure effective implementation of the voluntary RGPP.

B. Implementation of the Objectives The objectives identified have been implemented at the Oyster Creek Generating Station through compliance with approved procedures EN-AA-408-4000, Radiological Groundwater Protection Program Implementation and site specific procedure EN-OC-408-4160, RGPP Reference Material for Oyster Creek Generating Station.C. Program Description Samples for the OCGS site were collected for Exelon by on-site personnel and Normandeau Associates, Inc. This section describes the general collection methods used to obtain environmental samples for the OCGS RGPP in 2014. Sample locations can be found in Table A-i, Appendix A.1. Sample Collection Samples of water are collected, managed, transported and analyzed in accordance with approved procedures.

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.2. Sample Analysis Samples are analyzed in accordance with approved procedures that are based on industry standards.

3. Quality Control Analytical laboratories are subject to internal quality assurance programs, industry cross-check programs, nuclear industry audits, as well as being certified by the State of New Jersey.4. Data Interpretation Station personnel review and evaluate all analytical data deliverables as data is 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 the 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 10 days.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.

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 (18.6 keV 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.Ill. Program Description A. Sample Analysis This section describes the general analytical methodologies used by TBE to analyze the environmental samples for radioactivity for the Oyster Creek Generating Station RGPP in 2014. The sampling frequencies are increased if activity is detected.

In order to achieve the stated objectives, the current program includes the following analyses for groundwater, surface water, and precipitation water: 1. Gamma emitters 2. Strontium-89 and Strontium-90

3. Tritium 4. Gross Alpha, Dissolved and Suspended and Gross Beta, Dissolved and Suspended 5. Selected transuranics

6. Fe-55 7. Ni-63 B. Data Interpretation The radiological data collected prior to Oyster Creek Generating Station becoming operational, as well as background data from publicly available databases, 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 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 as 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.C. Background Analysis 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 peaked in 1963 with the signing of the limited test ban treaty. 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 in 1986.b. Precipitation Data Precipitation samples are routinely collected at stations around the world for the analysis of tritium and other radionuclides.

One publicly available database that provides tritium concentrations in precipitation is the USEPA's RadNet database.

RadNet provides tritium precipitation concentration data for samples collected at stations throughout the U.S. from 1978 up to and including 1996.Tritium concentrations in precipitation in New Jersey from 1978 through 1996 have ranged from 600 pCi/I in 1979 to 0 pCi/I in 1996, with an average of 185 pCi/I. Tritium concentrations in wells may still be above the 200 pCi/I 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 surface water bodies, including Oyster Creek and the Delaware River. New Jersey surface water data between 1978 and 1998 averaged 185 pCi/I.The USEPA RadNet surface water data typically has a reported 'Combined Standard Uncertainty' of 2 standard deviations.

This corresponds to a +/- 36 to +/-100 pCi/I confidence bound on each given reported measurement so that the typical surface water background data provided by RadNet may be subject to measurement uncertainty of up to 100 pCi/I.

The radio-analytical laboratory counts tritium results to an Exelon specified LLD of 200 pCi/I with a typical uncertainty of +/-100 pCi/I. Therefore, sample results reported by TBE near this LLD can not be distinguished from natural background concentrations in surface water.IV. Results and Discussion A. Program Exceptions

1. Sample Anomalies There are no sample anomalies in 2014.2. Missed Samples Exelon maintains a Radiological Groundwater Protection Program (RGPP) as part of the nuclear industry's voluntary groundwater protection initiative as described in NEI 07-07. As part of this program, samples are obtained routinely from monitoring wells and surface waters at Oyster Creek based on the frequencies outlined in station procedures.

The following samples were not obtained as required by procedure:

MW-51-Tritium, monthly-Gamma, semi-annually

-Gross alpha, annually-Gross beta, annually-Select transuranics, annually-Iron-55, annually-Nickel-63, annually-Strontium-89, annually-Strontium-90, annually Immediate actions taken: MW-51 was dry 12 out of 12 months during sampling events. MW-51 is checked for water each sampling event and no additional actions are required.

3. LLDs Not Met Required LLDs for Surface and Groundwater Isotope pCi/liter H-3 200 Mn-54 15 Co-58 15 Fe-59 30 Co-60 15 Zn-65 30 Nb-95 15 Zr-95 30 1-131 15 Cs-134 15 Cs-137 18 Ba-140 60 La-140 15 Pu-241 50 Fe-55 200 Ni-63 5 Sr-89 10 Sr-90 1 Gross Alpha (diss) 3 Gross Alpha (susp) 10 Gross Beta (diss) 4 Gross Beta (susp) 4 Transuranics 0.2 Indicated LLDs for shorter lived radionuclides were not met due to a time lag between taking the samples and analyzing the samples as indicated on table B-1.2 and B-11.2.B. Groundwater Results Samples were collected from on-site locations in accordance with the station radiological groundwater protection program. As reported in CRA's 2011 Hydrogeologic Investigation Report, groundwater flow in the vicinity of the Torus Water Storage Tank and the Condensate Storage Tank is towards the intake and discharge canals.Tritium Samples from 54 locations were analyzed for tritium activity (Table B-1.1, Appendix B). Tritium was detected in 29 of 209 samples.The values ranged from < 200 to 26,835 pCi/I. The well with the highest concentration was MW-561 (Table B-1.1, Appendix B).Strontium Strontium-89 and strontium-90 were not detected in any location sampled in 2014. (Table B-1.1, Appendix B)Gross Alpha and Gross Beta (dissolved and suspended)

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the second sampling in 2014.There were 48 samples taken from 43 groundwater well locations.

Gross Alpha (dissolved) was detected in 11 samples and ranged from 0.4 to 4.7 pCi/L. Gross Alpha (suspended) was detected in 20 samples and ranged from 1.4 to 29.1 pCi/L. Gross Beta (dissolved) was detected in 41 samples and ranged from 1.6 to 29.4 pCi/L. Gross Beta (suspended) was detected in 22 samples and ranged from 1.8 to 215 pCi/L.Gamma Emitters Gamma emitting nuclide K-40 was detected in nine of 54 samples analyzed during 2014. The concentrations ranged from 35 to 248 pCi/L. (Table B-1.2, Appendix B)."Hard-To-Detect""Hard-To-Detect" analyses were performed on a select group of groundwater locations.

The analyses for groundwater included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-234, U-235, and U-238. U-234 and U-238 were detected in three of eight samples. The concentrations of U-234 and U-238 ranged from 0.27 to 0.81 pCi/L and 0.13 to 1.30 pCi/L, respectively.

All other Hard-To-Detect analyses were less than the MDC.Occasionally the isotopes of U-234 and U-238 are detected and are considered background (Table B-1.3, Appendix B).C. Surface Water Results Samples were collected from on-site locations in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.Tritium Samples from 4 locations were analyzed for tritium activity (Table B-11.1, Appendix B). No detectable tritium (greater than the LLD)was found in any surface water samples collected from onsite and offsite monitoring locations.

Gross Alpha and Gross Beta (dissolved and suspended)

Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions are not required on a routine basis and were not analyzed in 2014.Gamma Emitters Gamma emitting nuclide, naturally occurring potassium-40, was detected in 264 of 266 samples analyzed.

The concentrations ranged from 89 to 580 pCi/L. (Table B-11.2, Appendix B)"Hard-To-Detect""Hard-To-Detect" analyses are not required on a routine basis and were not analyzed in 2014.D. Precipitation Water Results Precipitation samples were collected from onsite and offsite locations in accordance with the station radiological groundwater protection program. Analytical results and anomalies are discussed below.Tritium Samples from five locations were analyzed for tritium activity (Table B-Ill.1, Appendix B). No detectable tritium (greater than the LLD)was found in any precipitation water samples collected from onsite and offsite monitoring locations.

E. Summary of Results -Inter-Laboratory Comparison Program Inter-Laboratory Comparison Program results for TBE and Environmental Inc. (Midwest Labs) are presented in the 2014 Oyster Creek AREOR.

This report is part of the AREOR.F. Leaks, Spills, and Releases There were no abnormal liquid releases during 2014.G. Trends Active remediation of tritium in groundwater due to the spills that occurred in 2009 was initiated in October 2010. Trending of the data due to active remediation is on-going.

Overall, the station has seen a decreasing trend in tritium values.H. Investigations Conestoga Rovers and Associates performed an independent assessment of the tritium plume.
