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 2013 through 31 December 2013. During that time period, 1618 analyses were performed on 1223 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 2013.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 and crabs.Cesium-1 37 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. Cesium-1 37 was detected at low levels consistent with those detected in previous years. 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 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 11/4 miles east of the Garden State Parkway. The site property extends about 22 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), Landauer and Environmental Inc. (Midwest Labs) on samples collected during the period 01 January 2013 through 31 December 2013.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, 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 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 4 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 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 5 is well below the applicable levels set by the Nuclear Regulatory Commission (NRC) and the EPA.There were liquid radioactive effluent releases during 2013 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 361 days in 2013. The Continuous releases occurred from January 1, 2013 through December 27, 2013 with a total of 3.50E+07 gallons of groundwater pumped resulting in 2.28E-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 1.37E-06 mrem.Utilizing gaseous effluent data, the maximum hypothetical dose to any individual during 2013 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 4.93E-01 mrem (0.493mrem) which was approximately 3.29 percent of the annual limit of 15 mrem. 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 1.42E-03 mrem (0.00142 mrem) which was 2.84E-02 percent of the annual limit of 5 mrem.The total maximum organ dose (Bone) due to all radiological effluents of 4.97E-01 mrem (0.497 mrem) received by any individual from gaseous effluents from the Oyster Creek Generating Station for the reporting period is more than 603 times lower than the dose the average individual in the Oyster Creek area 6 received from background radiation, including that from radon, 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 2013, 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 5.39 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 2013. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-i, 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 (1N, 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: A site boundary 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 intermediate distance ring 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 8 population.

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 2013. 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 OCGS.C. Data Interpretation For trending purposes, the radiological and direct radiation data collected during 2013 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 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, 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, 10 Ba-140, and La-140 were reported.For fish eight nuclides:

K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, 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-137 were reported.For air iodine cartridges one nuclide: 1-131 was reported.For vegetation seven nuclides:

Be-7, 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 2013 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, 2013 through December 31, 2013. The station was off line for this time period.2. Station 1 N (On-site northern domestic well) Month of February sample is a composite of 2 weeks instead of 4 weeks. No sample for weeks of 2/17/13 and 2/24/13, station out of service.Due to limited volume sample was consumed for the 1-131 (Low Level) analysis, therefore, the gamma, gross beta and H-3 analyses could not be performed.

1. Station 66 (SE of site, east of Route 9 and south of the OCGS Discharge Canal) No samples for the month of July. The garden's growth was slower than the other gardens and there was not enough sample for the month.2. Station 66 (SE of site, east of Route 9 and south of the OCGS Discharge Canal) No cabbage was available for the month of October.3. Station 115 (East of Site, on Finninger Farm) No cabbage was available for the month of October.4. Station 66 (SE of site, east of Route 9 and south of the OCGS Discharge Canal) Kale was not available for the entire growing season.*NOTE: Per the Oyster Creek ODCM, if garden vegetation samples are unobtainable due to any legitimate reason, the missed sample will be documented in the annual report, with no further actions necessary.

Program exceptions are tracked and investigated to understand the 13 causes of the program exception.

Sampling and maintenance errors are 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 The Exelon procedure for orientation of REMP air sample stations was revised from "Ensure sampling devices are oriented towards the average prevailing wind" to "Ensure sampling devices are oriented in the centerline toward the power station".

This affected air sample stations 3, 66, 71, and 72.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). 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 14 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 2013 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, 1 N 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 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.

2013 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-I1.2, Appendix C). Gross beta was detected in 43 of 57 samples, and is expected due to natural sources and fallout residual from previous bomb 15 testing. The values ranged from 1.5 to 17.7 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 1N 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.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-I1.3, Appendix C). All results were less than the MDC.Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-I1.4, 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.16 Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-I11.2, Appendix C). All nuclides were less than the MDC.4. Fish Fish samples comprised of bottom feeder (black drum, red drum, summer flounder, and tautog) and predator (striped bass, bluefish, weakfish, and white perch) 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 3,207 to 5,429 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.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 1,356 to 2,199 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 17 600 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 1,983 to 2,718 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). Potassium-40 was found at all stations and ranged from 975 to 19,000 pCi/kg dry.Cesium-I137 was not detected in any of the samples. No fission or activation products were found. Figure C-3, Appendix C graphs Cs-137 concentrations in sediment from 1984 through 2013 and figure C-2, Appendix C graphs Co-60 concentrations in sediment from 1984 through 2013.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-1 70-1000, Radiological Environmental Monitoring Program and Meteorological Program Implementation, Attachment 1, Analytical Results Investigation Levels, includes sediment investigation level for Cs-137 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 2013 aquatic monitoring results for surface 18 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 2013 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:

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 7 to 39 E-3 pCi/m 3 with a mean of 15 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 7 to 32 E-3 pCi/m 3 with a mean of 15 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 the 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 19 ranged from 1.90E-2 to 2.77E-1 pCi/m3. 2013 gross beta activity values ranged from <6E-3 to 39E-3 pCi/m3. The 2013 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 30 to 77 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.20

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 18 of 40 samples.The values ranged from 3.5 to 23.3 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

(-,99%) is from weapons testing fallout. Approximately 16.8 million 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 21 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 2,124 to 6,601 pCi/kg wet. Naturally occurring Be-7 was detected in 21 of 40 samples and ranged from 131 to 1,265 pCi/kg wet.Cesium-137 was detected in nine of 40 samples and ranged from 37 to 130 pCi/kg wet. These results are consistent with historical operational data. 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-137 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-1 37 concentrations in soil were non-detectable.

Vegetation samples exhibited Cs-1 37 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.The level of Cs-137 in the REMP samples did not approach any regulatory limits or reporting levels, and is not unusual given the known environmental levels of this radionuclide 22 attributable to atmospheric nuclear weapons testing and the Chernobyl accident.In conclusion, terrestrial monitoring results for vegetation samples during 2013 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 15.9 to 29.4 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 23.6 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 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 2013 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 2013 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 23 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.Distance in Feet from the OCGS Reactor Building Sector Residence Garden*(ft) (if)1 N 5,655 8,224 2 NNE 3,239 6,015 3 NE 3,245 8,736 4 ENE 5,704 6,445 5 E 6,549 1,756 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 17,613 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: 24

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 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 TBE laboratory, 178 out of 185 analyses performed met the specified acceptance criteria.

Seven analyses (Sr-89 and Sr-90 in milk, Co-57, Zn-65 and Sr-90 in soil, Cs-1 34 in air particulate and Sr-90 in vegetation

[two low warning in a row]) did not meet the specified acceptance criteria or internal QA requirements for the following reason: 1 .Teledyne Brown Engineering's Analytics September 2013 Sr-89 in milk result of 63.9 pCi/L was lower than the known value of 96.0 pCi/L. The failure was a result of analyst error and was specific to the Analytics sample. Client samples for the associated time period were evaluated and no client samples were affected by this failure. NCR 13-15 25

2. Teledyne Brown Engineering's Analytics September 2013 Sr-90 in milk result of 8.88 pCi/L was lower than the known value of 13.2 pCi/L. The failure was a result of analyst error and was specific to the Analytics sample. Client samples for the associated time period were evaluated and no client samples were affected by this failure. NCR 13-15 3. & 4. Teledyne Brown Engineering's MAPEP September 2013 Co-57 and Zn-65 in soil were evaluated as failing the false positive test.While MAPEP evaluated the results as failures, the gamma software listed the results as non identified nuclides.

The two nuclides would never have been reported as detected nuclides to a client. MAPEP does not allow laboratories to put in qualifiers for the submitted data nor "less than" results. MAPEP evaluates results based on the relationship between the activity and the uncertainty.

MAPEP spiked the soil sample with an extremely large concentration of Eu-152, which was identified by the gamma software as an interfering nuclide, resulting in forced activity results that were evaluated by MAPEP as detected Co-57 and Zn-65. No client samples were affected by these failures.

NCR 13-14 5. Teledyne Brown Engineering's MAPEP September 2013 Sr-90 in soil result of 664 Bq/kg was higher than the known value of 460 Bq/kg, exceeding the upper control limit of 598 Bq/kg. An incorrect Sr-90 result was entered into the MAPEP database.

The correct Sr-90 activity of 322 Bq/kg would have been evaluated as acceptable with warning. No client samples were affected by this failure. NCR 13-14 6. Teledyne Brown Engineering's MAPEP September 2013 Cs-134 in air particulate activity of -0.570 Bq/sample was evaluated as a failed false positive test, based on MAPEP's evaluation of the result as a significant negative value at 3 standard deviations.

A negative number would never have been reported as a detected nuclide to a client, therefore no client samples were affected by this failure.NCR 13-14 7. Teledyne Brown Engineering's MAPEP September 2013 Sr-90 in vegetation result was investigated due to two low warnings in a row. It appears the September sample was double spiked with carrier, resulting in a low activity.

With a recovery of around 50%lower, the Sr-90 result would have fallen within the acceptance range. No client samples were affected by this issue. NCR 13-14 For the EIML laboratory, 89 of 92 analyses met the specified acceptance criteria.

Three analyses (AP -Gross Alpha, Soil -Sr-90 and Co-57) did not meet the specified acceptance criteria for the following reasons: 26

1. Environmental Inc., Midwest Laboratory's MAPEP February 2013 air particulate gross alpha result of 0.14 Bq/total sample was lower than the known value of 1.20 Bq/total sample, exceeding the lower control limit of 0.36 Bq/total sample. The filter was recounted overnight.

No significant activity could be detected.2. Environmental Inc., Midwest Laboratory's MAPEP February 2013 soil Co-57 result of 408.40 Bq/kg was lower than the known value of 628.0 Bq/kg, exceeding the lower control limit of 440.0 Bq/kg.The sample was reanalyzed using additional fuming nitric separations.

The reanalysis result of 574.4 fell within the control limits.Environmental Inc., Midwest Laboratory's MAPEP August 2013 soil Co-57 result of 699.60 Bq/kg was higher than the known value of 0.00 Bq/kg, exceeding the upper control limit of 5.00 Bq/kg.Interference from Eu-1 52 resulted in misidentification of Co-57.The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.V.

Errata A. Teledyne Brown Engineering (TBE) provides data results [activity, uncertainty and minimum detectable concentration

{MDC}]. We are required to calculate the MDC using a multiplier of 4.66.27 MDA = At 2.22 (v)(y) (a)(c)Where: At = counting time for sample (minutes)03 = background rate of instrument blank (cpm)2.22 = dpm/pCi or: 2.22 x 106 dpm/pCi v = volume or mass of sample analyzed y = chemical yield E = efficiency of the counter The formulas for calculating the activity, uncertainty and MDC are contained in the software of the counting equipment.

For the gamma system, when the new detector number 08 was added to the system in January 2012, the default value of 3.29 was used to calculated the MDCs on detector 08. The activity and uncertainty were not affected.

The multiplier has been changed from 3.29 to the required 4.66.When the MDCs are recalculated using 4.66, the MDC values will increase by 41.6%. The greatest impact will be on the short-lived nuclides which have an LLD requirement, e.g. 1-131, Ba-140 and La-140. Which means there could be some missed LLDs which will be identified in the Errata Data Appendix table of the 2013 annual report. This is not a reportable issue for the NRC. There is also the possibility that naturally produced nuclides that were detected would become a non-detect, e.g Th-228, Th-230, etc.B. Oyster Creek determines the direct radiation to the public by subtracting the average of the control stations from the measurements from the sample stations (sample station millirem -average of control station millirem = net millirem to the public). The graph (Appendix C, Figure C-7)displays the gross millirem readings from the dosimetry.

With the change from TLD to OSLD a high bias in the gross millirem was noted at all locations.

This bias was not seen after the net millirem was determined.

C. For the TBE laboratory, 180 out of 186 analyses performed met the specified acceptance criteria in 2012. Six analyses (Co-60, Gross Alpha, Gross Beta, Sr-89, Sr-90 and Zn-65) did not meet the specified acceptance criteria for the following reason: 28

1. Teledyne Brown Engineering's MAPEP March 2012 Co-60 in soil result of 7.61 Bq/kg was higher than the known value of 1.56 Bq/kg, resulting in a found to known ratio of 4.88 on a sensitivity evaluation.

NCR 12-08 was initiated to investigate this failure. Due to massive amount of Cs-1 34 (22400 pCi/kg), a minor Cs-1 34 gamma line at 1168 keV caused erroneous counts to show up in the 1173 keV peak of Co-60. The 1332 peak for Co-60 was unaffected by the interference.

The potential for this interference was noted for future reference.

TBE is monitoring the Co-60 in soil analyses on a case-to-case basis.2. Teledyne Brown Engineering's MAPEP March 2012 Zn-65 in AP result of 4.19 Bq/sample was higher than the known value of 2.99 Bq/sample, exceeding the upper control limit of 3.89 Bq/sample.

NCR 12-08 was initiated to investigate this failure. Co-60 has a gamma energy at 1172 keV which is very near to the Zn-65 1115 keV line. The Co-60 easily passed with a ratio of 1.20 found/known.

No cause could be found for the failure and is considered an anomaly specific to the MAPEP sample. The first and second quarter 2012 Analytics AP Zn-65 analyses were acceptable.

3. Teledyne Brown Engineering's MAPEP September 2012 Sr-90 in water result of 19.6 pCi/L was higher than the known value of 12.2 pCi/L, exceeding the upper control limit of 15.9 pCi/L. NCR 12-11 was initiated to investigate this failure. An incorrect aliquot was entered into LIMS. Using the correct aliquot, the result would have fallen within the acceptance range. Remedial training for the technician including a review of the procedure and discussion of the specific error was performed.

4. Teledyne Brown Engineering's ERA May 2012 Gross Alpha in water result of 82.4 pCi/L was higher than the known value of 62.9 pCi/L, which exceeded the upper control limit of 78.0 pCi/L. NCR 12-05 was initiated to investigate this failure. The G-1 detector is slightly biased high for Th-230 based measurements.

All power plant gross alpha measurements are based on an Am-241 efficiency which more accurately represents potential alpha contaminants from a nuclear power plant. Th-230 efficiency is used for gross alpha in EPA potable water measurements.

No nuclear power plant data was affected by this failure. The G-1 detector is used only for ERA samples. The detector was recalibrated.

5. Teledyne Brown Engineering's ERA November 2012 Gross Beta in water result of 59.3 pCi/L was higher than the known value of 39.2 29 pCi/L, which exceeded the upper control limit of 46.7 pCi/L. NCR 12-13 was initiated to investigate this failure. The rerun result of 44.8 fell within the control limits. It appears an incorrect aliquot was entered into LIMS. Remedial training for the technician including a review of the procedure and discussion of the specific error was performed.

6. Teledyne Brown Engineering's ERA November 2012 Sr-89 in water result of 46.5 pCi/L was higher than the known value of 39.1 pCi/L, which exceeded the upper control limit of 46.1 pCi/L. NCR 12-13 was initiated to investigate this failure. The found to known ratio was 1.19, which TBE considers acceptable with warning. TBE's internal QA program, the MAPEP program, and the Analytics program all allow for an acceptance range of 0.70 -1.30 for radioanalytical cross check samples. The Sr-89 ratio of 1.19 is well within this acceptance range.D. 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

(-,99%) is from weapons testing fallout. Approximately 16.8 million 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.30 APPENDIX A RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT

Panasonic Model 814 TLDs were used in the second, third, and fourth quarters of 200 1.*Oyster Creek's dosimetry changed from TLD to OSLD in 2012. Due to the dosimeter change, OSLD values appear higher.

Oyster Creek determines the direct radiation to the public by subtracting the average of the control stations from the measurements from the sample stations (sample station millirem -average of control station millirem = net millirem to the public). The graph (Appendix C, Figure C-7) displays the gross millirem readings from the dosimetry.

With the change from TLD to OSLD a high bias in the gross millirem was noted at all locations.

This bias was not seen after the net millirem was determined.

b Laboratory codes as follows: MAW (water), MAAP (air filter), MASO (soil), MAVE (vegetation).

c 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 filter was recounted overnight, no significant alpha activity could be detected.(2) The sample was reanalyzed using additional fuming nitric separations.

Result of reanalysis:

574.4 +/- 35.2 Bq/kg.(3) Interference from Eu-152 resulted in misidentification of Co-57.E-9 APPENDIX F ERRATA DATA Due to an incorrect setting on gamma detector 08, 3.29 rather than 4.66 was used in the MDC calculation.

Nonconformance 13-07 was initiated and corrective actions have been implemented to address this issue. All samples counted on detector 08 were reprocessed using the correct calculation.

As a result, all MDCs for these samples have increased by 41.6%. The previously reported activities and uncertainties were not affected.

In some cases, the increased MDC resulted in missed LLDs. All samples with MDCs affected by this issue are listed below. The samples with missed LLDs are shown in the table for 2011, 2012, and 2013.

The graph (Appendix C, Figure C-7) displays the gross millirem readings from the dosimetry.

With the change from TLD to OSLD a high bias in the gross millirem was noted at all locations.

This bias was not seen after the net millirem was determined.
