PLANT HATCH 1 INTRODUCTION The Radiological Environmental Monitoring Program (REMP) was conducted in accordance with Chapter 4 of the Offsite Dose Calculation Manual (ODCM). The REMP activities for 2019 were reported herein in accordance with Technical Specification (TS) 5.6.2 and ODCM 7.1.

The objectives of the REMP were to:

1) Determine the levels of radiation and the concentrations of radioactivity in the environs and;

2) Assess the radiological impact (if any) to the environment due to the operation of the Edwin I.

Hatch Nuclear Plant (HNP).

The assessments included comparisons between the results of analyses of samples obtained at locations where radiological levels were not expected to be affected by plant operation (control stations), areas of higher population (community stations), and at locations where radiological levels were more likely to be affected by plant operation (indicator stations), as well as comparisons between preoperational and operational sample results.

HNP is owned by Georgia Power Company (GPC), Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia, and Dalton Utilities. The plant is located in Appling County, Georgia on the southwest side of the Altamaha River near Baxley, Georgia. Unit 1, a General Electric Company Boiling Water Reactor (BWR) with a licensed core thermal output of 924 Megawatts (MWt), began commercial operation on December 31, 1975. Unit 2, also a General Electric Company BWR rated for 924 MWt, began commercial operation on September 5, 1979.

The pre-operational stage of the REMP began with the establishment and activation of the environmental monitoring stations in January of 1972. The operational stage of the REMP began on September 12, 1974 with Unit 1 initial criticality.

A description of the REMP is provided in Section 2 of this report

Section 3 provides a Summary of the results, an assessment of any radiological impacts to the environment, and the results from the interlaboratory comparison

A summary of the land use census and the river survey are included in Section 4

Conclusions are included in Section 5 2019 HNP Annual Radiological Environmental Operating Report llPage

PLANT HATCH 2 REMP DESCRIPTION The following section provides a description of the sampling and laboratory protocols associated with the REMP. Table 2-1 provides a summary of the sample types to be collected and the analyses to be performed in order to monitor the airborne, direct radiation, waterborne and ingestion pathways, and also summarizes the collection and analysis frequencies (in accordance with ODCM Section 4.2). Table 2-2 provides specific information regarding the station locations, their proximity to the plant, and exposure pathways. Additionally, Appendix A of this report provides Maps A-1 through A-3 that depict the georeferenced location of sampling stations. Any Errata from previous reports are provided in Appendix B. All data points resulting from REMP sampling are provided in Appendix C.

Beginning in October 2017 and continuing through 2019, a contractor through Southern Nuclear Operating Company (SNC) provided services for the collection of most of the REMP samples, only fish samples were collected by the Alabama Power Company. All samples were analyzed by the Georgia Power Environmental Lab (GPCEL) in Atlanta, Georgia. The GPCEL analyzed all REMP samples.

,tation 172 was located approximately 3.0 river miles downstream of the discharge structure for river water, (Sediment and clams, and 1.7 river miles for fish.

rrhe locations from which river water and sediment may be taken can be sharply defined. However, the sampling locations for clams often have to be extended over a wide area to obtain a sufficient quantity. High water adds o the difficulty in obtaining clam samples and may also make an otherwise suitable location for sedimen1 sampling unavailable. A stretch of the river of a few miles or so was generally needed to obtain adequate fish samples. The mile locations given above represent approximations of the locations where samples were

~ollected.

PLANT HATCH 3 RESULTS

SUMMARY

Included in this section are statistical evaluations of the laboratory results, comparison of the results by media, and a summary of the anomalies and deviations. Overall, 877 analyses were performed across nine exposure pathways. Tables and figures are provided throughout this section to provide an enhanced presentation of the information.

In recent history, man-made nuclides have been released into the environment and have resulted in wide spread distribution of radionuclides across the globe. For example, atmospheric nuclear weapons tests from the mid-1940s through 1980 distributed man-made nuclides around the world. The most recent atmospheric tests in the 1970s and in 1980 have had a significant impact upon the radiological concentrations found in the environment prior to and during pre-operation, and through early operation. Some long-lived radionuclides, such as Cs-137, continue to be detected and a portion of these detections are believed to be attributed to the nuclear weapons tests.

Additionally, data associated with certain radiological effects created by off-site events have been removed from the historical evaluation, this includes: the nuclear atmospheric weapon test in the fall of 1980, the Chernobyl incident in the spring of 1986 and the Fukushima accident in the spring of 2011.

As indicated in ODCM 7.1.2.1, the results for naturally occurring radionuclides that are also found in plant effluents must be reported along with man-made radionuclides. Historically, the radionuclide Be-7, which occurs abundantly in nature, is often detected in REMP samples, and occasionally detected in the plant's liquid and gaseous effluents. When it is detected in effluents and REMP samples, it is also included in the REMP results. In 2019, Be-7 was not detected in plant effluents and therefore it was not included in this report. The Be-7 detected in select REMP samples likely represents naturally occurring and/or background conditions As part of the data evaluation process, SNC considered the impact of the non-plant associated nuclides along with a statistical evaluation of the REMP data. The statistical evaluations included within this report include the Minimum Detectable Concentration (MDC), the Minimum Detectable Difference (MOD), and Chauvenet's Criterion as described below.

Minimum Detectable Concentration The minimum detectable concentration is defined as an estimate of the true concentration of an analyte required to give a specified high probability that the measured response will be greater than the critical value.

Minimum Detectable Difference The Minimum Detectable Difference (MOD) compares the lowest significant difference (between the means) of a control station, versus an indicator station or a community 2019 HNP Annual Radiological Environmental Operating Report 7 1Page

PLANT HATCH station, that can be determined statistically at the 99% Confidence Level (CL). A difference in mean values which was less than the MDD was considered to be statistically indiscernible. The MDD is used to evaluate the statistical proximity between the indicator/community and control sample results, but generally, any results that are less than the MDC and/or Reporting Levels (RL) are considered to have minimal impact on the surrounding environs.

Chauvenet's Criterion All results were tested for conformance with Chauvenet's Criterion (G. D. Chase and J. L.

Rabinowitz, Principles of Radioisotope Methodology, Burgess Publishing Company, 1962, pages 87-90) to identify values which differed from the mean of a set by a statistically significant amount. Identified outliers were investigated to determine the reason(s) for the difference. If equipment malfunction or other valid physical reasons were identified as causing the variation, the anomalous result was excluded from the data set as non-representative.

Table 3-1 summarizes and evaluates the annual results for the indicator stations against the control and community stations (where applicable) and as appropriate, results were evaluated against the MDCs (listed in Table 3-1) and RLs (listed in Table 3-2). The required MDCs were achieved during laboratory sample analysis. The 2019 results were compared with previous results, including those obtained during pre-operation. No data points were excluded for violating Chauvenet's Criterion.

PLANT HATCH 3.1 Airborne Particulates As specified in Table 2-1, airborne particulate filters and charcoal canisters were collected weekly at four indicator stations (Stations 103, 107, 112 and 116) which encircle the plant at the site periphery and at two control stations (Station 304 and 309) which is approximately 10 miles from the main stack. At each sampling location containing a filter and cartridge series, air was continuously drawn through a glass fiber filter to retain airborne particulate and an activated charcoal canister was placed in series with the particulate filter in order to adsorb radioiodine.

3.1.1 Gross Beta As provided in Table 3-1, the 2019 annual average weekly gross beta activity was 19.7 fCi/m3 for the indicator stations. It was 0.2 fCi/m3 less than the control station average of 19.9 fCi/m3 for the year. No MOD was applied since the indicator average was less than the control.

Average Air Gross Beta historical data (Table 3-4) is graphed to show trends associated with a prevalent exposure pathway (Figure 3-1). In general, there was close agreement between the results for the indicator, control and community stations. This close agreement supports the position that the plant was not contributing significantly to the gross beta concentrations in air.

Airborne Radioiodine 131 was not detected in the air cartridges at either the indicator or control stations in 2019. Historically, gamma isotopes have been detected as a result of offsite events. On only one occasion since 1986, has a man-made radionuclide been detected in a quarterly composite. A small amount of Cs-137 (1.7 fCi/m3} was identified in the first quarter of 1991 at Station 304. The MDC and RL for Cs-137 in air are 60 and 20,000 fCi/m3, respectively.

PLANT HATCH 3.2 Direct Radiation In 2019, direct (external) radiation was measured with Optically Stimulated Luminescent (OSLO) dosimeters by placing two OSLO badges at each station. The gamma dose at each station was reported as the average reading of the two badges. The badges were analyzed on a quarterly basis. An inspection was performed near mid-quarter for offsite badges to ensure that the badges were on-station and to replace any missing or damaged badges.

Two direct radiation stations were established in each of the 16 compass sectors, to form two concentric rings. The inner ring (Stations 101 through 116) was located near the plant perimeter as shown in Map A-1 in Appendix A and the outer ring (Stations 201 through 216) was located at distances of four to five miles from the plant as shown in Map A-2 in Appendix A. The stations in the East sector were a few additional miles away with regards to the other stations in their respective rings due to large swamps making normal access extremely difficult. The 16 stations forming the inner ring were designated as the indicator stations. The two-ring configuration of stations was established in accordance with NRC Branch Technical Position "An Acceptable Radiological Environmental Monitoring Program", Revision 1, November 1979. The three control stations (Nos. 304, 309 and 416) were located at distances greater than 10 miles from the plant as shown in Map A-2. The mean and range values presented in the "Other" column in Table 3-1 includes the outer ring stations (stations 201 through 216) as well as stations 064 and 301, which monitor special interest areas. Station 064 was located at the onsite roadside park, while Station 301 was located near the Toombs Central School. Station 210, in the outer ring, was located near the Altamaha School (the only other nearby school).

As provided in Table 3-1, the 2019 average quarterly exposure at the indicator stations (inner ring) was 11.4 mR with a range of 8.6-18.6 mR. The indicator station average was 0.1 mR less than the control station average (11.5 mR with a range of 10.1-12.9 mR). No MOD was applied since the indicator average was less than the control.

The quarterly exposures acquired at the community/other (outer ring) stations during 2019 ranged from 7.3 to 17.3 mR with an average of 11.1 mR which was also less than control station average.

Average Direct Radiation historical data (Table 3-5) is graphed to show trends associated with a prevalent exposure pathway (Figure 3-2). The decrease between 1991 and 1992 values was attributed to a change in Thermoluminescent Dosimeters (TLDs) from Teledyne to Panasonic. It should be noted however that the differences between indicator and control and outer ring values did not change. The increase shown in 2010 reflected issues with the aging Panasonic TLD reader. The close agreement between the station groups has supported the position that the plant was not contributing significantly to direct radiation in the environment.

PLANT HATCH 3.3 Biological Media Cs-137 was the only radionuclide analyzed across all three biological mediums. As indicated in Figure 3-4, the Cs-137 activity levels were below the respective MDCs and well below that of the respective Rls for each sample media for both the indicator and control stations.

3.3.1 Milk In accordance with Tables 2-1 and 2-2, milk samples were collected semi-monthly from Station 304 {the state prison dairy) which was a control station located more than 10 miles from the plant. Since 1989, efforts to locate a reliable milk sample source within five miles of the plant have been unsuccessful and the 2019 land census did not identify a milk animal within five miles of the plant.

Gamma isotopic {including 1-131 and Cs-137) analyses were performed on each collected milk sample and there were no detectable results for gamma isotopes.

3.3.2 Vegetation In accordance with Tables 2-1 and 2-2, vegetation (forage) samples were collected monthly for gamma isotopic analyses at two indicator locations near the site boundary {Stations 106 and 112) and at one control station located about 21 miles from the plant {Station 416). Cs-137 was detected in both the indicator {average of 36.8 pCi/kg-wet) or control station samples {average of 7.5 pCi/kg-wet). This difference of 29.2 pCi/kg-wet is greater than the MDD of 16.9 pCi/kg-wet, which indicates a statistically discernible difference. However, the values are well below the MDC and RL for Cs-137 and are therefore not considered as an impact to the environment. The man-made radionuclide Cs-137 is periodically identified in vegetation samples and is generally attributed to offsite sources {such as weapons testing, Chernobyl, and Fukushima).

While Cs-137 and 1-131 were periodically found in vegetation samples during pre-operation, the historical trends and the relationship between the indicator and control stations demonstrate that plant operations were having no adverse impact to the environment. The sample results have consistently been below the MDC and the RL for Cs-137 {80 and 2000 pCi/kg-wet, respectively).

During 2019, outside of Cs-137, no man-made gamma isotopes were detected in any Hatch REMP vegetation samples.

3.3.3 Fish Fish samples were collected in accordance with the ODCM {as indicated in Table 2-1). For the semi-annual collections, the control location {Station 170) was located upriver of the plant intake 2019 HNP Annual Radiological Environmental Operating Report 19 I Page

P LANT HATCH structure, and the indicator location (Station 172) was located downriver of the plant discharge structure.

Laboratory analysis did not indicate any radionuclide activity in 2019.

3.3.4 Biological Media Summary There were no statistical differences, trends, or anomalies associated with the 2019 biological media samples when compared to historical data. Figure 3-4 below, details the 2019 Cs-137 concentration compared to the MDC.

3.4 Surface Water Composite river water samples were collected monthly at one upstream control location and at one downstream indicator location (shown on Map A-3 in Appendix A). The details of the sampling protocols are outlined in Tables 2-1 and Table 2-2. A gamma isotopic analysis was conducted on each monthly sample. The monthly aliquots were combined to form quarterly composite samples in order to be analyzed for tritium.

As provided in Table 3-1, there were no positive results during 2019 from the gamma isotopic analysis of the river water samples. Also indicated in Table 3-1, the average tritium concentration found at the indicator station was -80.2 pCi/I which was 6.9 pCi/I more than the average at the control station (-73.3 pCi/I). No MDD was calculated because both averages were negative.

3.5 Sediment Sediment was collected along the shoreline of the Altamaha River in the spring and fall at the upstream control station (No. 170) and the downstream indicator station (No. 172). A gamma isotopic analysis was performed on each sample. There were no man-made radionuclides detected in sediment samples, except for Cs-137, which is plotted along with biological media (Cs-137 across all detected mediums} in Section 3.3.4 and Figure 3-4. The Cs-137 average at the indicator stations was 43.60 pCi/kg which was 13.0 p/Ci/kg more than the control station average of 30.6 pCi/kg. No MOD was applied because the amount of samples are too small, however the values for Cs-137 in sediment were both below the MDC of 180 pCi/kg.

3.6 lnterlaboratory Comparison Program In accordance with ODCM 4.1.3, GPCEL participated in an lnterlaboratory Comparison Program (ICP} which satisfied the requirements of Regulatory Guide 4.15, Revision 1, "Quality Assurance for Radiological Monitoring Programs (Normal Operations} - Effluent Streams and the Environment", February 1979. The ICP included the required determinations (sample medium/radionuclide combinations} included in the REMP.

The ICP was conducted by Eckert & Ziegler Analytics, Inc. (EZA} of Atlanta, Georgia. EZA has a documented Quality Assurance (QA} program and the capability to prepare Quality Control (QC) materials traceable to the National Institute of Standards and Technology. The ICP is a third-party 2019 HNP Annual Radiological Environmental Operating Report 21 I Page

PLANT HATCH blind testing program which provided a means to ensure independent checks were performed on the accuracy and precision of the measurements of radioactive materials in environmental sample matrices. EZA supplied the crosscheck samples to GPCEL which performed routine laboratory analyses. Each of the specified analyses was performed three times.

The accuracy of each result was measured by the normalized deviation, which is the ratio of the reported average less the known value to the total error. An investigation was undertaken whenever the absolute value of the normalized deviation was greater than three or whenever the coefficient of variation was greater than 15% for all radionuclides other than Cr-51 and Fe-

59. For Cr-51 and Fe-59, an investigation was undertaken when the coefficient of variation exceeded the values shown on Table 3-6 below:

As required by ODCM 4.1.3.3 and 7.1.2.3, a summary of the results of the GPCEL's participation in the ICP is provided in Table 3-7 for:

gross beta and gamma isotopic analyses of an air filter

gamma isotopic analyses of milk samples

gross beta, tritium and gamma isotopic analyses of water samples The 2019 analyses included tritium, gross beta and gamma emitting radio-nuclides in different matrices. The attached results for all analyses were within acceptable limits for accuracy (less than 15% coefficient of variation and less than 3.0 normalized deviations, except for Cr-51 and Fe-59, which are outlined in Table 3-6).

PLANT HATCH 3.7 Groundwater To ensure compliance with NEI 07-07 (Industry Ground Water Protection Initiative - Final Guidance Document), Southern Nuclear developed the Nuclear Management Procedure, Radiological Groundwater Protection Program. The procedure contains detailed site-specific monitoring plans, program technical bases, and communications protocol (to ensure that radioactive leaks and spills are addressed and communicated appropriately). In an effort to prevent future leaks of radioactive material to groundwater, SNC plants have established buried piping and tanks inspection programs. No changes were made to the Groundwater Protection Program in 2019.

Plant Hatch maintained the following wells (Table 3-8), which were sampled at a frequency that satisfied the requirements of NEI 07-07. Table 3-9 contains the results of the Groundwater Protection Program for tritium (in pCi/L). See Map A-4 in Appendix A for well locations.

NDM - No Detectable Measurement Plant Hatch has had historic tritium leaks into the perched aquifer from around the Unit 1 Condensate Storage Tank (CST}, documented on 10 CFR 50.75{g} records. The tritium values in the wells that were found to be elevated above MDC were from previous CST and related piping leaks and were not considered present issues. In accordance with NEI 07-07 2.2.a, voluntary communication was made with State/local stakeholders on December 4, 2018 with regards to an identified release around the CST-2 area. This event is reflected in the tritium value of NW-10.

The source of the leak has been repaired and tritium values have turned asymptotic. Historic leaks and spills were reported in accordance with NEI 07-07.

PLANT HATCH 4 SURVEY SUMMARIES 4.1 Land Use Census In accordance with ODCM 4.1.2, a land use census was conducted on November 7, 2019 that circumscribed each of the 16 compass sectors within a five mile radius in order to verify the locations of the nearest radiological receptor. The land use census results are tabulated in Table 4-1. The 2019 land use census did not indicate any major changes from 2018, therefore, a revision to the ODCM will not be required. Residents were located in each sector as identified below; no resident was identified closer than the current closest resident.

2019 HNP Annual Radiological Environmental Operating Report 28 I Page

PLANT HATCH Correspondence from the Georgia Environmental Protection Division (EPD) on October 29, 2019, indicated that no new agricultural or drinking water withdrawal permits had been issued at that time.

4.3 Meteorological Report Summary The meteorological tower data collected throughout the year is analyzed and compared to previous results by a third-party consultant. For 2019, the meteorological tower data were comparable to previous years, as related to precipitation amounts (53.22") and wind direction (from south-southwest at 10m, from the northeast at 60m and 100m). Therefore, no changes to REMP monitoring locations are warranted.

PLANT HATCH 5 CONCLUSIONS This report has confirmed SNCs conformance with the requirements of Chapter 4 of the ODCM and the objectives were to:

1) Determine the levels of radiation and the concentrations of radioactivity in the environs and;

2) Assess the radiological impact (if any) to the environment due to the operation of the HNP.

Based on the 2019 activities associated with the REMP, SNC offers the following conclusions:

Samples were collected and there were no deviations or anomalies that negatively affected the quality of the REMP

Land use census and river survey did not reveal any changes

Analytical results were below reporting levels

These values were consistent with historical results which indicate no adverse radiological environmental impacts associated with the operation of HNP 2019 HNP Annual Radiological Environmental Operating Report 30I Page

PLANT f ARLEY 1 INTRODUCTION The Radiological Environmental Monitoring Program (REMP) was conducted in accordance with Chapter 4 of the Offsite Dose Calculation Manual (ODCM). The REMP activities for 2019 were reported herein in accordance with Technical Specification (TS} 5.6.2 and ODCM 7.1.

The objectives of the REMP were to:

1) Determine the levels of radiation and the concentrations of radioactivity in the environs and;

2) Assess the radiological impact (if any} to the environment due to the operation of the Joseph M. Farley Nuclear Plant {FNP).

The assessments included comparisons between results of analyses of samples obtained at locations where radiological levels were not expected to be affected by plant operation (control stations), areas of higher population {community stations), and at locations where radiological levels were more likely to be affected by plant operation (indicator stations), as well as comparisons between preoperational and operational sample results.

FNP is owned by Alabama Power Company (APC} and operated by Southern Nuclear Operating Company (SNC). The plant is located in Houston County, Alabama approximately fifteen miles east of Dothan, Alabama on the west bank of the Chattahoochee River. Unit 1, a Westinghouse Electric Corporation Pressurized Water Reactor (PWR) with a licensed core thermal power output of 2775 Megawatts thermal (MWt}, achieved initial criticality on Au~ust 9, 1977 and was declared 11 commercial" on December 1, 1977. Unit 2, also a 2775 MWt Westinghouse PWR, achieved initial criticality on May 8, 1981 and was declared "commercial" on July 30, 1981.

The preoperational stage of the REMP began with initial sample collections in January of 1975.

The transition from the preoperational to the operational stage of the REMP was marked by Unit 1 initial criticality.

A description of the REMP is provided in Section 2 of this report

Section 3 provides a summary of the results, an assessment of any radiological impacts to the environment, and the results from the lnterlaboratory Comparison

A summary of the land use census and the river survey are included in Section 4

Conclusions are included in Section 5 2019 FNP Annual Radiological Environmental Operating Report ljPage

PLANT FARLEY 2 REMP DESCRIPTION The following section provides a description of the sampling and laboratory protocols associated with the REMP. Table 2-1 provides a summary of the sample types to be collected and the analyses to be

\

performed in order to monitor the airborne, direct radiation, waterborne and ingestion pathways, and also summarizes the collection and analysis frequencies (in accordance with ODCM Section 4.2).

Notes:

Airborne particulate sample filters were analyzed for gross beta radioactivity 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or more after sampling to allow for radon and thoron daughter decay. If gross beta activity In air particulate samples was greater than 10 times the yearly mean of control samples, gamma Isotopic analysis was performed on the individual samples.

2Gamma Isotopic analysis means the Identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from he facility.

Upriver sample was taken at a distance beyond significant influence of the discharge. Downriver samples were taken beyond but near the mixing zone.

'Composite sample aliquots were collected at time intervals that were very short (e.g., hourly) relative to the compositing period (e.g., monthly) to ensure obtaining a representative sample.

5 A milking animal is a cow or goat producing milk for human consumption, no milk animals were found within five miles of the plant, a control sample not collected since 2009.

6 1f the gamma isotopic analysis Is not sensitive enough to meet the Minimum Detectable Concentration (MDC) for 1-131, a separate analysis for 1-131 may be performed.

'These collections were normally made at river mile 41.3 for the indicator station and river mile 47 .8 for the control station; however, due to river bottom sediment shifting caused by high flows, dredging, etc., collections may be made from river mile 40 to 42 for the indicator station and from river mile 47 to 49 for the control station.

8 Since several miles of river water may be needed to obtain adequate fish samples, these river mile positions represent the approximate locations from which the fish are taken. Collections for the indicator station should be from river mile 37.5 to 42.5 and for the control station from river mile 47 to 52.

PLANT FARLEY 3 RESULTS

SUMMARY

Included in this section are statistical evaluations of the laboratory results, comparison of the results by media, and a summary of the anomalies and deviations. Overall, 1,019 analyses were performed across nine exposure pathways. Tables and figures are provided throughout this section to provide an enhanced presentation of the information.

In recent history, man-made nuclides have been released into the environment and have resulted in wide spread distribution of radionuclides across the globe. For example, atmospheric nuclear weapons tests from the mid-1940s through 1980 distributed man-made nuclides around the world. The most recent atmospheric tests in the 1970s and in 1980 have had a significant impact upon the radiological concentrations found in the environment prior to and during pre-operation, and through early operation. Some long-lived radionuclides, such as Cs-137, continue to be detected and a portion of these detections are believed to be attributed to the nuclear weapons tests.

Additionally, data associated with certain radiological effects created by off-site events have been removed from the historical evaluation, this includes: the nuclear atmospheric weapon test in the fall of 1980, the Chernobyl incident in the spring of 1986 and the Fukushima accident in the spring of 2011.

As indicated in ODCM 7.1.2.1, the results for naturally occurring radionuclides that are also found in plant effluents must be reported along with man-made radionuclides. Historically, the radionuclide Be-7, which occurs abundantly in nature, is often detected in REMP samples, and occasionally detected in the plant's liquid and gaseous effluents. When it is detected in effluents and REMP samples, it is also included in the REMP results. In 2019, Be-7 was not detected in any plant effluents and therefore it was not included in this report. The Be-7 detected in select REMP samples likely represents naturally occurring and/or background conditions.

As part of the data evaluation process, SNC considered the impact of the non-plant associated nuclides along with a statistical evaluation of the REMP data. The statistical evaluations included within this report include the Minimum Detectable Concentration {MDC), the Minimum Detectable Difference {MDD), and Chauvenet's Criterion as described below.

Minimum Detectable Concentration The minimum detectable concentration is defined as an estimate of the true concentration of an analyte required to give a specified high probability that the measured response will be greater than the critical value.

2019 FNP Annual Radiological Environmental Operating Report SI Page

PLANT FARLEY Minimum Detectable Difference The Minimum Detectable Difference (MDD) compares the lowest significant difference (between the means) of a control station versus an indicator or a community station, that can be determined statistically at the 99% Confidence Level (CL). A difference in mean values which was less than the MOD was considered statistically indiscernible. The MOD is used to evaluate the statistical proximity between the indicator/community and control sample results, but generally, any results that are less than the MDC and/or Reporting Levels (RL) are considered to have minimal impact on the surrounding environs.

Chauvenet's Criterion All results were tested for conformance with Chauvenet's Criterion (G. D. Chase and J. L.

Rabinowitz, Principles of Radioisotope Methodology, Burgess Publishing Company, 1962, pages 87-90) to identify values which differed from the mean of a set by a statistically significant amount. Identified outliers were investigated to determine the reason(s) for the difference. If equipment malfunction or other valid physical reasons were identified as causing the variation, the anomalous result was excluded from the data set as non-representative.

Table 3-1 summarizes and evaluates the annual results for the indicator stations against the control and community stations (where applicable) and as appropriate, results were evaluated against the MDCs (listed in Table 3-1) and Rls (listed in Table 3-2). The required MDCs were achieved during laboratory sample analysis. The 2019 results were compared with previous results, including those obtained during pre-operation. No data points were excluded for violating Chauvenet's Criterion.

(a)The MDC is defined in ODCM 10.1. Except as noted otherwise, the values listed in this column are the detection capabilities required by ODCM Table 4-3. The values listed in this column are a priori (before the fact) MDCs. In practice, the a posteriori (after the fact) MDCs are generally lower than the values listed.

(b) Mean and range were based upon detectable measurements only. The fraction of all measurements at a specified location that are detectable is placed in parenthesis.

(c) No Detectable Measurement(s) (NDM).

(d) The Georgia Power Company Environmental Laboratory has determined that this value may be routinely attained under normal conditions. No value is provided in ODCM Table4-3.

(e) Item 3 of ODCM Table4-1 implies that an 1-131 analysis is not required to be performed on water samples when the dose calculated from the consumption of water is less than 1 mrem per year. However, 1-131 analyses have been performed on the finished drinking water samples.

(f) "Other" stations, as identified in the "Station Type* column of Table 2-2, are "Community" and/or "Special" stations.

PLANT FARLEY 3.1 Airborne Particulates As specified in Table 2-1, airborne particulate filters and charcoal canisters were collected weekly at three indicator stations (Stations 0701, 1101, and 1601) which encircle the plant at the site periphery, at three community station (0703, 1108, and 1605) approximately three to eight miles from the plant, and at two control stations (0215 and 1218) which range from approximately 15 to 18 miles from the plant. At each sampling location containing a filter and cartridge series, air was continuously drawn through a glass fiber filter to retain airborne particulate and an activated charcoal canister was also placed in series with the particulate filter in order to adsorb radioiodine at each indicator/control station and at community station 0703 in Cedar Springs, GA for comparison purposes with the Georgia Environmental Protection Division (EPD).

3.1.1 Gross Beta As provided in Table 3-1, the 2019 annual average weekly gross beta activity was 17.5 fCi/m3 for the indicator stations. It was less than the control station average of 17.7 fCi/m3 for the year, therefore no MDD was calculated.

The 2019 annual average weekly gross beta activity at the community stations was 18.1 fCi/m3 which was 0.4 fCi/m3 more than the control station average. The difference was less than the calculated MDD of 1.9 fCi/L, so the difference was not statistically discernible.

Average Air Gross Beta historical data (Table 3-4) is graphed to show trends associated with a prevalent exposure pathway (Figure 3-1). In general, there was a close agreement between the results for the indicator, control and community stations. This close agreement supports the position that the plant was not contributing significantly to the gross beta concentrations in air.

Indicator Control Community 3.1.2 Gamma Particulates and Airborne Radioiodine During 2019, no man-made radionuclides were detected from the gamma isotopic analysis of the quarterly composites of the air particulate filters other than Be-7, as discussed previously, Be-7 is a naturally occurring isotope and was not released from plant operations and is therefore not further evaluated here.

2019 FNP Annual Radiological Environmental Operating Report 17 I Page

PLANT FARLEY 1-131 was not detected in the air cartridges at either the indicator or control stations in 2019.

Historically, gamma isotopes have been detected as a result of offsite events. During pre-operation, Cs-137 was occasionally detected.

3.2 Direct Radiation In 2019, direct (external) radiation was measured with Optically Stimulated Luminescent (OSL) dosimeters by placing two OSL badges at each station. The gamma dose at each station was reported as the average reading of the two badges. The badges were analyzed on a quarterly basis. An inspection was performed near mid-quarter for offsite badges to ensure that the badges were on-station and to replace any missing or damaged badges.

Two direct radiation stations were established in each of the 16 compass sectors, to form two concentric rings. The inner ring (Stations 0101 through 1601) was located near the plant perimeter as shown in Map A-1 in Appendix A and the outer ring (Stations 0104 through 1605}

was located at approximately 5 miles (varying distances) from the plant as shown in Map A-2 in Appendix A. The 16 stations forming the inner ring were designated as the indicator stations. The two-ring configuration of stations was established in accordance with NRC Branch Technical Position "An Acceptable Radiological Environmental Monitoring Program", Revision 1, November 1979. The six control stations (Stations 0215, 0718, 1215, 1218, 1311 and 1612) were located at varying distances greater than 10 miles from the plant as shown in Map A-3 in Appendix A.

Monitored special interest areas consist of the following: Station 1001 which was the nearest residence to the plant, and Station 1108 in the town of Ashford, Alabama. The mean and range values presented in the "Other" column in Table 3-1 includes the outer ring stations (stations 0104 through 1605} as well as stations 1001 and 1108.

As provided in Table 3-1, the 2019 average quarterly exposure at the indicator stations (inner ring) was 15.2 mR with a range of 10.8 to 24.5 mR. The indicator station average was identical to the control station average (15.2 mR; range 10.8 mR to 21.7mR). The MDD was not calculated because the control average was identical to the indicator average. These values are consistent with historical readings, where the indicator and control are closely correlated.

The quarterly exposures acquired at the community/other (outer ring) stations during 2019 ranged from 9.0 -17.7 mR with an average of 12.8 mR which was 2.4 mR less than that of the control stations (15.2 mR). The MDD does not apply since the average is less than that of the control average.

Average Direct Radiation historical data (Table 3-5) is graphed to show trends associated with a prevalent exposure pathway (Figure 3-2). The decrease between 1991 and 1992 values was attributed to a change in Thermoluminescent Dosimeters (TLDs) from Teledyne to Panasonic. It should be noted however that the differences between indicator and control and outer ring values did not change. The increase shown in 2010 reflected issues with the aging Panasonic TLD 2019 FNP Annual Radiological Environmental Operating Report 18 I Page

PLANT FARLEY reader. The close agreement between the station groups has supported the position that the plant was not contributing significantly to direct radiation in the environment.

Figure 3-3 provides a more detailed view of the 2019 values. The values for the indicator and special interest areas detailed below indicate that Plant Farley did not significantly contribute to direct radiation at those areas.

PLANT FARLEY 3.3 Biological Media Cs-137 was the only radionuclide detected in one of the three biological media. As indicated in Figure 3-4, the Cs-137 activity levels were below the respective MDCs and well below that of the respective Rls for each sample media for both the indicator and control stations.

3.3.1 Milk Milk samples had been collected biweekly from a control location until the end of 2009 when the dairy would no longer provide samples. No indicator station (a location within five miles of the plant) has been available for milk sampling since 1987. As discussed in Section 4.0, no milk animals were found within five miles of the plant during the 2019 land use census and no milk sampling was performed during the reporting year (no available sources from control locations).

3.3.2 Vegetation In accordance with Table 2-1 and 2-2, forage (vegetation) samples were collected every four weeks at two indicator stations on the plant perimeter, and at one control station located approximately 18 miles west of the plant in Dothan, Alabama. The man-made radionuclide Cs-137 were periodically identified in vegetation samples and was generally attributed to offsite sources (such as weapons testing, Chernobyl, and Fukushima).

During 2019, Cs-137 was identified in one sample at the control station, FB-1218-Ml (Dothan, Alabama). The control station average (and single value) was 35.5 pCi/L (no range, with only one positive). This average was based only on the detectable values; all other results were below detection limits. No environmental concerns were noted since the results were well below the RL of 2,000 pCi/L for Cs-137 in vegetation.

Be-7 was also detected in vegetation during 2019, but was not released in plant effluents throughout the year. This further illustrates the abundance of naturally-occurring Be-7 present in the surrounding environment.

3.3.3 Fish In accordance with Table 2-1, two types of fish (bottom-feeding and game) were collected on a semiannually basis from the Chattahoochee River at a control station several miles upstream of the plant intake structure and at an indicator station a few miles downstream of the plant discharge structure. These locations are shown in Map A-3 in Appendix A.

3.3.3.1 Bottom Feeding Species No radionuclides were identified from the control or indicator samples in 2019.

2019 FNP Annual Radiological Environmental Operating Report 21 I Page

PLANT FARLEY 3.3.3.2 Game Species No radionuclides were identified from the control or indicator samples in 2019.

3.3.4 Biological Media Summary There were no statistical differences, trends, or anomalies associated with the 2019 biological media samples when compared to historical data. Cs-137 was occasionally present in biological media, as with previous sample results; however, the detections were consistently below both the MDC or RL. No other reportable radionuclides were found from the gamma isotopic analysis of biological media samples in 2019.

3.4 Off-site Groundwater There were no true indicator sources of offsite ground water near Plant Farley. A well, located approximately four miles south-southeast of the plant on the east bank of the Chattahoochee River, serves Georgia Pacific Paper Company as a source of potable water. This well was designated as the indicator station. A deep well located about 1.2 miles southwest of the plant supplies water to the Whatley residence. This well was designated as the control station.

Samples were collected quarterly and analyzed for gamma isotopic, 1-131 and tritium as specified in Table 2-1. In 2019, there were no radionuclides detected in any of the ground water samples from either sample station, apart from tritium.

Since 2004, tritium has been identified at very low concentrations (near the instrument detection level) and close to environmental background levels in off-site groundwater. In 2019, tritium was detected in indicator station WGl-07 at an average of-64.7 pCi/L (range of-169 to 38.2 pCi/L). It was also detected in the control station at an average of-36.8 pCi/L (range of-174 to 77.3 pCi/L).

These results were very close to the instrument detection limitations and were at concentrations well below the MDC and RL for tritium in drinking water (2,000 and 20,000 pCi/I, respectively).

These values represent background conditions for tritium in drinking water and were not attributable to plant activity. Also, note that negative values in radionuclide activity represent contamination factors (e.g. laboratory equipment) subtracted from the laboratory result.

3.5 River (Surface) Water Composite river water samples were collected monthly at one upstream control location and one downstream indicator location (shown on Map A-2). The details of the sampling protocols are outlined in Tables 2-1 and Table 2-2. A gamma isotopic analysis was conducted on each monthly sample. The monthly aliquots were combined in the lab to form quarterly composite samples in order to be analyzed for tritium.

2019 FNP Annual Radiological Environmental Operating Report 221 Page

l PLANT FARLEY As provided in Table 3-1, there were no positive results during 2019 from the gamma isotopic analysis of the river water samples. Tritium was detected in each of the quarterly composites at the indicator station, with an average of 142 pCi/L (range of 47-268). Tritium in the control station in each of the composites had an average value of 56.4 pCi/L (range -92 to 157 pCi/L). The positive tritium results for both the indicator and control were all less than the MDC and RL limits (2,000 pCi/1 and 20,000 pCi/1, respectively) for tritium in a drinking water supply source. No MDD was calculated because of the level of negative values. These values represent background conditions for tritium in drinking water and were not attributable to plant activity. Also, note that negative values in radionuclide activity represent contamination factors (e.g. laboratory equipment) subtracted from the laboratory result.

Figure 3-4 below details the 2019 average tritium concentrations across both water mediums.

A gamma isotopic analysis was performed on each sample. There were no reportable radionuclides detected in sediment samples in 2019.

3.7 lnterlaboratory Comparison Program In accordance with ODCM 4.1.3, GPCEL participated in an lnterlaboratory Comparison Program (ICP) which satisfied the requirements of Regulatory Guide 4.15, Revision 1, "Quality Assurance 2019 FNP Annual Radiological Environmental Operating Report 23 I Page

PLANT FARLEY for Radiological Monitoring Programs (Normal Operations) - Effluent Streams and the Environment", February 1979. The ICP included the required determinations (sample medium/radionuclide combinations) included in the REMP.

The ICP was conducted by Eckert & Ziegler Analytics, Inc. (EZA) of Atlanta, Georgia. EZA has a documented Quality Assurance (QA) program and the capability to prepare Quality Control (QC) materials traceable to the National Institute of Standards and Technology. The ICP is a third-party blind testing program which provided a means to ensure independent checks were performed on the accuracy and precision of the measurements of radioactive materials in environmental sample matrices. EZA supplied the crosscheck samples to GPCEL which performed routine laboratory analyses. Each of the specified analyses was performed three times.

The accuracy of each result was measured by the normalized deviation, which is the ratio of the reported average less the known value to the total error. An investigation was undertaken whenever the absolute value of the normalized deviation was greater than three or whenever the coefficient of variation was greater than 15% for all radionuclides other than Cr-51 and Fe-

59. For Cr-51 and Fe-59, an investigation was undertaken when the coefficient of variation exceeded the values shown on Table 3-6 below:

For air filters, concentration units are pCi/filter. For all other media, concentration units are pCi/liter (pCi/1).

As required by ODCM 4.1.3.3 and 7.1.2.3, a summary of the results of the GPCEL's participation in the ICP is provided in Table 3-7 for:

gross beta and gamma isotopic analyses of an air filter

gamma isotopic analyses of milk samples

gross beta, tritium and gamma isotopic analyses of water samples The 2019 analyses included tritium, gross beta and gamma emitting radio-nuclides in different matrices. The attached results for all analyses were within acceptable limits for accuracy (less than 15% coefficient of variation and less than 3.0 normalized deviations, except for Cr-51 and Fe-59, which are outlined in Table 3-6).

PLANT f ARLEY 3.8 Groundwater To ensure compliance with NEI 07-07 (Industry Ground Water Protection Initiative - Final Guidance Document), Southern Nuclear developed the Nuclear Management Procedure, Radiological Groundwater Protection Program. The procedure contains detailed site-specific monitoring plans, program technical bases, and communications protocol (to ensure that radioactive leaks and spills are addressed and communicated appropriately). In an effort to prevent future leaks of radioactive material to groundwater, SNC plants have established buried piping and tanks inspection programs. No changes were made to the Groundwater Protection Program in 2019.

Plant Farley maintained the following wells (Table 3-8), which were sampled at a frequency that satisfied the requirements of NEI 07-07. The analytical results for 2019 were all within regulatory limits specified within this report. Table 3-9 contains the results of the Groundwater Protection Program for tritium (in pCi/L).

PLANT FARLEY 4 SURVEY SUMMARIES 4.1 Land Use Census In accordance with ODCM 4.1.2, a land use census was conducted on December 21, 2019 that circumscribed each of the 16 compass sectors within a five mile radius in order to verify the locations of the nearest radiological receptor. A milk animal is a cow or goat producing milk for human consumption. The census results are tabulated in Table 4.1. The 2019 land use census indicated that there were no changes to the nearest location for any of the categories in any of the sectors when compared to the 2017 census, nor were any milk animals located within a five-mile radius.

In July 2013, the Georgia Department of Natural Resources issued a farm use permit to withdraw from the Chattahoochee River to the Nature Conservancy of Georgia. The Nature Conservancy of Georgia leases property along the river for agricultural and grazing purposes to a private farm family, and water from the river could potentially be used for crop irrigation. At the time of this report, no water has been withdrawn and used for crop irrigation by the landowners.

PLANT FARLEY In the fall of 2019, the Georgia Environmental Protection Division (EPD), Alabama Department of Environmental Management (ADEM) and Alabama Department of Economic and Community Affairs (ADECA) was contacted to request any information about river use permits that had been issued in the area near the plant. No additional withdrawal permits or intake locations had been added at the time of the survey.

4.3 Meteorological Report Summary The meteorological tower data collected throughout the year is analyzed and compared to previous results by a third-party consultant. For 2019, the meteorological tower data were comparable to previous years, as related to precipitation amounts (49.17") and wind direction (from northwest at 10m, from the southwest at 45m). Therefore, no changes to REMP monitoring locations are warranted.

PLANT FARLEY 5 CONCLUSIONS This report has confirmed SN Cs conformance with the requirements of Chapter 4 of the ODCM and the objectives were to:

1) Determine the levels of radiation and the concentrations of radioactivity in the environs; and

2) Assess the radiological impact {if any) to the environment due to the operation of the FNP.

Based on the 2019 activities associated with the REMP, SNC offers the following conclusions:

Samples were collected and there were no deviations or anomalies that negatively affected the quality of the REMP

Land use census and river survey did not reveal any changes

Analytical results were below reporting levels

These values were consistent with historical results which indicate no adverse radiological environmental impacts associated with the operation of FNP 2019 FNP Annual Radiological Environmental Operating Report 31 I Page

PLANT VOGTLE 1 INTRODUCTION The Radiological Environmental Monitoring Program (REMP) was conducted in accordance with Chapter 4 of the Offsite Dose Calculation Manual {ODCM). The REMP activities for 2019 were reported herein in accordance with Technical Specification (TS) 5.6.2 and ODCM 7.1.

The objectives of the REMP were to:

1) Determine the levels of radiation and the concentrations of radioactivity in the environs and;

2) Assess the radiological impact (if any) to the environment due to the operation of the Alvin W.

Vogtle Electric Generating Plant (VEGP).

The assessments included comparisons between results of analyses of samples obtained at locations where radiological levels were not expected to be affected by plant operation (control stations), areas of higher population (community stations), and at locations where radiological levels were more likely to be affected by plant operation (indicator stations), as well as comparisons between preoperational and operational sample results.

VEGP is owned by Georgia Power Company (GPC), Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia, and the City of Dalton, Georgia. It is located on the southwest side of the Savannah River approximately 23 river miles upstream from the intersection of the Savannah River and U.S. Highway 301. The site is in the eastern sector of Burke County, Georgia, across the river from Barnwell County, South Carolina. The VEGP site is directly across the Savannah River from the Department of Energy Savannah River Site (SRS). Unit 1, a Westinghouse Electric Corporation Pressurized Water Reactor {PWR), with a licensed core thermal power of 3,626 Megawatts (MWt), received its operating license on January 16, 1987 and commercial operation started on May 31, 1987. Unit 2, also a Westinghouse PWR rated for 3,626 MWt, received its operating license on February 9, 1989 and began commercial operation on May 19, 1989. Both units were relicensed on June 3, 2009.

The pre-operational stage of the REMP began with initial sample collections in August of 1981.

The transition from the pre-operational to the operational stage of the REMP occurred as Unit 1 reached initial criticality on March 9, 1987.

A description of the REMP is provided in Section 2 of this report

Section 3 provides a summary of the results, an assessment of any radiological impacts to the environment, and the results from the interlaboratory comparison

A summary of the land use census and the river survey are included in Section 4

Conclusions are included in Section 5 2019 VEGP Annual Radiological Environmental Operating Report lJPage

PLANT VOGTLE 2 REMP DESCRIPTION The following section provides a description of the sampling and laboratory protocols associated with the REMP. Table 2-1 provides a summary of the sample types to be collected and the analyses to be performed in order to monitor the airborne, direct radiation, waterborne and ingestion pathways, and also summarizes the collection and analysis frequencies (in accordance with ODCM Section 4.2). Table 2-2 provides specific information regarding the station locations, their proximity to the plant, and exposure pathways. Additionally, Appendix A of this report provides Maps A-1 through A-4 that depict the georeferenced location of sampling stations. Any Errata from previous reports are provided in Appendix B. All data points resulting from REMP sampling are provided in Appendix C.

During 2019 a contractor through Southern Nuclear Operating Company (SNC) provided services for the collection of all of the REMP samples. The Georgia Power Central Environmental Laboratory (GPCEL) analyzed all REMP samples.

'A 5-mile stretch of the river was generally needed to obtain adequate fish samples. Samples were normally gathered between RM 153 and 158 for upriver collections and between RM 144 and 149.4 for downriver collections.

'Sediment was collected at locations with existing or potential recreational value. Because high water, shifting of the river bottom, or other reasons ould cause a suitable location for sediment collections to become unavailable or unsu itable, a stretch of the river between RM 148.S and 150.5 was designated for downriver collections while a stretch between RM 153 and 154 was designated for upriver collections. In practice, collections were normally made at RM lS0.2 for downriver collections and RM 153.3 for upriver collections.

5 The intake for the Cherokee Hill Water Treatment Plant was located on Abercorn Creek which is about one and a quarter creek miles from its mouth on he Savannah River at RM 29.

6 The intake for the Purrysburg Water Treatment Plant was located on the same canal as the Beaufort-Jasper Water Treatment Plant. The Purrysburg intake was closer to the Savannah River at the beginning of the canal.

Girard Dairy was considered an indicator station since It is the closest dairy to the plant (-5.5 miles). Dixon Dairy went out of business in June 2009 and Seven Oaks Dairy C7.5 miles) was added as a replacement and was considered a control station even though a control station is typically 10 miles or greater. Milky Way Dairy was identified and added to the OOCM in 2015 to replace Seven Oaks since it is at 16.0 miles from the plant.

PLANT VOGTLE 3 RESULTS

SUMMARY

Included in this section are statistical evaluations of the laboratory results, comparison of the results by media, and a summary of the anomalies and deviations. Overall, 2,690 analyses were performed across nine exposure pathways. Tables and figures are provided throughout this section to provide an enhanced presentation of the information.

In recent history, man-made nuclides have been released into the environment and have resulted in wide spread distribution of radionuclides across the globe. For example, atmospheric nuclear weapons tests from the mid-1940s through 1980 distributed man-made nuclides around the world. The most recent atmospheric tests in the 1970s and in 1980 have had a significant impact upon the radiological concentrations found in the environment prior to and during pre-operation, and through early operation. Some long-lived radionuclides, such as Cs-137, continue to be detected and a portion of these detections are believed to be attributed to the nuclear weapons tests.

Additionally, data associated with certain radiological effects created by off-site events have been removed from the historical evaluation, this includes: the nuclear atmospheric weapon test in the fall of 1980; the Chernobyl incident in the spring of 1986; abnormal releases from the Savannah River Site (SRS) during 1987 and 1991; and the Fukushima event in the spring of 2011.

As indicated in ODCM 7.1.2.1, the results for naturally occurring radionuclides that are also found in plant effluents must be reported along with man-made radionuclides. Historically, the radionuclide Be-7, which occurs abundantly in nature, is often detected in REMP samples, and occasionally detected in the plant's liquid and gaseous effluents. When it is detected in effluents and REMP samples, it is also included in the REMP results. In 2019, Be-7 was not detected in any plant effluents and therefore it was not included in this report. The Be-7 detected in select REMP samples likely represents naturally occurring and/or background conditions.

As part of the data evaluation process, SNC considered the impact of the non-plant associated nuclides along with a statistical evaluation of the REMP data. The statistical evaluations included within this report include the Minimum Detectable Concentration (MDC), the Minimum Detectable Difference (MDD), and Chauvenet's Criterion as described below.

Minimum Detectable Concentration The minimum detectable concentration is defined as an estimate of the true concentration of an analyte required to give a specified high probability that the measured response will be greater than the critical value.

2019 VEGP Annual Radiological Environmental Operating Report 91 Page

PLANT VOGTLE Minimum Detectable Difference The Minimum Detectable Difference (MOD) compares the lowest significant difference (between the means) of a control station, versus an indicator station or a community station, that can be determined statistically at the 99% Confidence Level. A difference in mean values which was less than the MDD was considered to be statistically indiscernible.

The MOD is used to evaluate the statistical proximity between the indicator/community and control sample results, but generally, any results that are less than the MDC and/or Reporting Levels (RL) are considered to have minimal impact on the surrounding environs.

Chauvenet's Criterion All results were tested for conformance with Chauvenet's Criterion (G. D. Chase and J. L.

Rabinowitz, Principles of Radioisotope Methodology, Burgess Publishing Company, 1962, pages 87-90} to identify values which differed from the mean of a set by a statistically significant amount. Identified outliers were investigated to determine the reason(s) for the difference. If equipment malfunction or other valid physical reasons were identified as causing the variation, the anomalous result was excluded from the data set as non-representative.

Table 3-1 summarizes and evaluates the annual results for the indicator stations against the control and community stations (where applicable) and as appropriate, results were evaluated against the MDCs (listed in Table 3-1} and Rls (listed in Table 3-2). The required MDCs were achieved during laboratory sample analysis. The 2019 results were compared with previous results, including those obtained during pre-operation. No data points were excluded for violating Chauvenet's Criterion.

PLANT VOGTLE 3.1 Airborne Particulates As specified in Table 2-1, airborne particulate filters and charcoal canisters were collected weekly at five indicator stations (Stations 3, 7, 10, 12 and 16} which encircle the plant at the site periphery, at a nearby community station (Station 35) approximately seven miles from the plant, and at a control station (Station 36) approximately 14 miles from the plant. At each sampling location containing a filter and cartridge series, air was continuously drawn through a glass fiber filter to retain airborne particulate and an activated charcoal canister was placed in series with the particulate filter to adsorb radioiodine.

3.1.1 Gross Beta As provided in Table 3-1, the 2019 annual average weekly gross beta activity at the indicator stations was 24.3 fCi/m3. It was 0.5 fCi/m3 more than the control station average of 23.8 fCi/m3.

The calculated MDD was 0.9 fCi/m3, which indicated that there was no discernible statistical difference between the two data sets.

The 2019 annual average weekly gross beta activity at the Girard community station was 24.0 fCi/m3 which was 0.2 fCi/m3 more than the control station average (23.8 fCi/m3). The calculated MDD was 1.5 fCi/m3, which indicated that there was no discernible statistical difference between the two data sets.

Average Air Gross Beta historical data (Table 3-4) is graphed to show trends associated with a prevalent exposure pathway (Figure 3-1). In general, there was close agreement between the results for the indicator, control and community stations. This close agreement supports the position that the plant was not contributing significantly to the gross beta concentrations in air.

Historically, gamma isotopes were detected as a result of offsite events. During pre-operation, Cs-134, Cs-137 and 1-131 were occasionally detected. In 1987, Cs-137 was found in one indicator composite at a concentration of 1.7 fCi/m3.

Additionally, 1-131 was also detected after the Fukushima incident in 2011, the highest 1-131 result in 2011 was 93.8 fCi/m3, which was approximately 10% of the RL. During 2019, no 1-131 was detected in the air cartridges at either the indicator or control stations.

PLANT VOGTLE 3.2 Direct Radiation In 2019, direct (external) radiation was measured with Optically Stimulated Luminescent dosimeters (OSLO) by placing two OSLO badges at each station. The gamma dose at each station was reported as the average reading of the two badges. The badges were analyzed on a quarterly basis. An inspection was performed near mid-quarter for offsite badges to ensure that the badges were on-station and to replace any missing or damaged badges.

Two direct radiation stations were established in each of the 16 compass sectors, to form two concentric rings. The inner ring (Stations 1 through 16) was located near the plant perimeter as shown in Map A-1 in Appendix A and the outer ring (Stations 17 through 32) was located at a distance of approximately five miles from the plant as shown in Map A-2 in Appendix A. The 16 stations forming the inner ring were designated as the indicator stations. The two ring configuration of stations was established in accordance with NRC Branch Technical Position "An Acceptable Radiological Environmental Monitoring Program", Revision 1, November 1979. The six control stations (Stations 36, 37, 47, 48, 51 and 52) were located at distances greater than 10 miles from the plant as shown in Map A-3 in Appendix A. Monitored special interest areas include Station 35 at the town of Girard and Station 43 at the employee recreational area (Rec Center).

The mean and range values presented in the "Other column in Table 3-1 includes the outer ring stations (stations 17 through 32) as well as stations 35 and 43.

As provided in Table 3-1, the 2019 average quarterly exposure at the indicator stations (inner ring) was 10.0 mR with a range of 6.1 to 16.8 mR. The indicator station average was 0.3 mR less than the control station average. No MOD was applied because the indicator was less than the control. Over the operational history, the annual average quarterly exposures have shown little variation between the indicator and control stations.

The quarterly exposures acquired at the community/other (outer ring) stations during 2019 ranged from 6.2 to 17.7 mR with an average of 10.4 mR which was 0.1 mR higher than the control station average. The calculated MOD was 0.6 mR, which indicated that there was no discernible statistical difference between the two data sets.

Average Direct Radiation historical data (Table 3-5) is graphed to show trends associated with this exposure pathway (Figure 3-2). The decrease between 1991 and 1992 values is attributed to a change in Thermoluminescent Dosimeters (TLDs) from Teledyne to Panasonic. It should be noted however that the differences between indicator and control and outer ring values did not change. The increase shown in 2010 reflected issues with the aging Panasonic TLD reader. The close agreement between the station groups has supported the position that the plant was not contributing significantly to direct radiation in the environment.

Indicator Control Community/Other Girard (Station 35) Rec Center (Station 43) 3.3 Biological Media Cs-137 was the only radionuclide detected in two of the three biological media. As indicated in Figure 3-4, the Cs-137 activity levels were below the respective MDCs and well below that of the respective RLs for each sample media for both the indicator and control stations.

3.3.1 Milk In accordance with Tables 2-1 and 2-2, milk samples were collected semi-monthly from two locations (until Girard stopped milk production in the fourth quarter): the Girard Dairy (Station 101) which was considered an indicator station because it is approximately 5.5 miles from Vogtle (ideally, a milk indicator station would be less than 5 miles from the plant); and the Milky Way Dairy (Station 102, at 16.0 miles from the plant) is the control location. No milk animal was found within five miles of Plant Vogtle during the 2019 land use census.

Gamma isotopic (including 1-131 and Cs-137) analyses were performed on each collected milk sample and there were no detectable results for gamma isotopes other than Cs-137, which was detected in 16 of 20 indicator samples (1.3 pCi/I average) and 9 of 21 control samples (0.9 pCi/I average). The difference was greater than the MDD of 0.34 pCi/I, therefore, there was a 2019 VEGP Annual Radiological Environmental Operating Report 22 IPage

PLANT VOGTLE statistically significant difference between the indicator and control. Both the indicator and control values were well under the MDC of 18 pCi/L, and these results were consistent with past milk samples, so no further investigation was conducted. Figure 3-4 provides the 2019 Cs-137 concentration in milk.

3.3.2 Vegetation In accordance with Tables 2-1 and 2-2, vegetation samples were collected monthly for gamma isotopic analyses at two indicator locations near the site boundary (Stations 7 and 15) and at one control station located about 17 miles WSW from the plant (Station 37). The man-made radionuclide Cs-137 was periodically identified in vegetation samples, and was generally attributed to offsite sources (such as weapons testing, Chernobyl, and Fukushima). Cs-137 was not detected in any samples collected in 2019 (indicator or control).

While Cs-137 and 1-131 were periodically found and Co-60 was discovered once in vegetation samples during pre-operation, the historical trends and the relationship between the indicator and control stations have demonstrated that plant operations were having no adverse impact to the environment. The sample results were consistently well below the MDC and the RL for Cs-137 (80 and 2000 pCi/kg-wet, respectively).

During 2019, there were also no other gamma isotopes detected in any Vogtle REMP vegetation samples.

3.3.3 Fish Fish samples were collected in accordance with the ODCM (as indicated in Table 2-1). For the semiannual collections, the control location (Station 81) extends from approximately two to seven miles upriver of the plant intake structure, and the indicator location (Station 85) extends from about 1.4 to seven miles downriver of the plant discharge structure. Fish sample results in 2019 were consistent with historical values.

3.3.3.1 Anadromous Species In accordance with Table 2-1, for anadromous species, all fish sampled were considered indicator stations. Anadromous fish were sampled once during 2019, on March 26. No radionuclides were detected in the 2019 anadromous fish sample.

3.3.3.2 Commercially or Recreationally Important Species As provided in Table 3-1, Cs-137 was found in the semiannual collections of commercially or recreationally important species of fish (for both indicator and control). The indicator station averaged a Cs-137 concentration of 77.4 pCi/kg-wet (detected in each sample, with a range of 39.9 to 114.9 pCi/kg-wet), and 47.3 pCi/kg-wet at the control station (detected in each sample, 2019 VEGP Annual Radiological Environmental Operating Report 23 IPage

PLANT VOGTLE with a range of 40.2 to 54.4pCi/kg-wet). There was no statistically discernible difference between the two since the difference of 30.1 is less than the MOD of 114. All detected values were well below the MDC for Cs-137 in fish {150 pCi/kg-wet). No other gamma nuclides were discovered in 2019.

3.3.4 Biological Media Summary There were no statistical differences, trends, or anomalies associated with the 2019 biological media samples when compared to historical data (below the MDC). Figure 3-4 below, details the 2019 Cs-137 concentrations in the three media types.

Milk Vegetation Fish Indicator Control 3.4 Drinking Water Samples were collected at an upstream control location and at three downstream indicator locations (shown on Map A-3) and further described in Table 2-2.

Monthly water samples were taken near the intake of each water treatment plant (raw drinking water) using automatic composite samplers. Additionally, monthly grab samples of the processed water effluent from the treatment plants (finished drinking water) were collected. Monthly aliquots from the raw and processed drinking water were analyzed for gross beta and gamma isotopic activity. The monthly aliquots were also combined to form quarterly composites in order to be analyzed for tritium.

2019 VEGP Annual Radiological Environmental Operating Report 24 IPage

PLANT VOGTLE For 2019, the indicator station average gross beta concentration in the raw drinking water was 3.1 pCi/L which was greater than the average gross beta concentration at the control station (2.3 pCi/L), but less than the MDD of 2. 7 pCi/L, so there is no statistical difference between the locations. Historically, the close agreement between the gross beta values of the indicator stations and the control station has supported that there was no significant gross beta contribution from the plant effluents. The required MDC for gross beta in water was 4.0 pCi/L; there was no RL for gross beta in water.

For 2019, the indicator station average gross beta concentration in the finished drinking water was 1.9 pCi/L which less than the average at the control station (2.1 pCi/L). Figure 3-5 shows the relationship between the average indicator station and average control station for 2019 in comparison to the MDC.

As provided in Table 3-1, there were no positive results during 2019 from the gamma isotopic analysis of the raw and finished drinking water samples.

Regarding tritium, the average raw drinking water indicator concentration was 273 pCi/L which was 99 pCi/L greater than the average concentration found at the control station (174 pCi/L). This difference does not exceed the MDD of 134 pCi/L, which would indicate a difference that is not statistically discernible, additionally all detected values were less than the MDC for drinking water of 2,000 pCi/L, and these values were consistent with past results.

The finished drinking water average tritium concentration at the indicator stations during 2019 was 245 pCi/L which was 149 pCi/L greater than the average concentration found at the control station (95 pCi/L). The MDD was calculated at 94. 7 pCi/L between the indicator and control stations, indicating a statistical difference. However, the averages were below the MDC for drinking water and the values were consistent with past results, coupled with the raw sample results, there does not appear to be an impact from plant operations. Figure 3-6 shows the tritium values in the drinking water compared to river water.

Raw Drinking Water Finished Drinking Water Indicator Control 3.5 River Water Composite river water samples were collected monthly at an upstream control location and at two downstream indicator locations (shown on Map A-3). The details of the sampling protocols are outlined in Tables 2-1 and Table 2-2. A gamma isotopic analysis was conducted on each monthly sample. The monthly aliquots were combined to form quarterly composite samples in order to be analyzed for tritium.

As provided in Table 3-1, there were no positive results during 2019 from the gamma isotopic analysis of the river water samples. Also indicated in Table 3-1, the average tritium concentration found at the indicator station was 711 pCi/L which was 636 pCi/L greater than the average at the control station (75 pCi/L). The river water tritium MDD was calculated to be 410 pCi/L, so the difference was statistically discernible. This increased tritium could likely be attributed to plant activity from Vogtle and other upstream dischargers (Plant Vogtle Unit 1 did have an abnormal tritium effluent value in 2019). Tritium was released regularly from the plant during normal operations, but always at levels that would not impact the MDC or RL.

At the "Other" river water sampling station (Station 84), the results ranged from 245 pCi/L to 503 pCi/L with an average of 358 pCi/L. The difference between the Station 84 and the control station was 283 pCi/L. The MDD was calculated to be 132 pCi/L, so the difference was statistically discernible. This increased tritium could likely be attributed to plant activity from Vogtle and other upstream dischargers. Tritium was released regularly from the plant during normal operations, but always at levels that would not impact the MDC or RL. Historically, the 2019 VEGP Annual Radiological Environmental Operating Report 26 IPage

PLANT VOGTLE relationship between the indicator/control stations and Station 84 has remained consistent.

Figure 3-6 below details the 2019 average tritium concentrations across the three water sample types.

River Water Raw Drinking Water Finished Drinking Water Special Indicator Control 3.6 Sediment Sediment was collected along the shoreline of the Savannah River in the spring and fall at Stations 81 and 83. Station 81 was a control station located about 2.5 miles upriver of the plant intake structure while Station 83 was an indicator station located about 0.6 miles downriver of the plant discharge structure. A gamma isotopic analysis was performed on each sample. The only radionuclide detected in 2019 samples was Be-7. Though Be-7 was detected in sediment, it will not be discussed within this report, because it was not detected in plant effluents and likely represents naturally occurring and/or background conditions.

There were no other radionuclides detected in the 2019 sediment samples.

3.7 lnterlaboratory Comparison Program In accordance with ODCM 4.1.3, GPCEL participated in an lnterlaboratory Comparison Program (ICP) which satisfied the requirements of Regulatory Guide 4.15, Revision 1, "Quality Assurance for Radiological Monitoring Programs {Normal Operations) - Effluent Streams and the 2019 VEGP Annual Radiological Environmental Operating Report 27 IPage

PLANT VOGTLE Environment", February 1979. The ICP included the required determinations (sample medium/radionuclide combinations) included in the REMP.

The ICP was conducted by Eckert & Ziegler Analytics, Inc. (EZA) of Atlanta, Georgia. EZA has a documented Quality Assurance (QA) program and the capability to prepare Quality Control (QC) materials traceable to the National Institute of Standards and Technology. The ICP is a third-party blind testing program which provided a means to ensure independent checks were performed on the accuracy and precision of the measurements of radioactive materials in environmental sample matrices. EZA supplied the crosscheck samples to GPCEL which performed routine laboratory analyses. Each of the specified analyses was performed three times.

The accuracy of each result was measured by the normalized deviation, which is the ratio of the reported average less the known value to the total error. An investigation was undertaken whenever the absolute value of the normalized deviation was greater than three or whenever the coefficient of variation was greater than 15% for all radionuclides other than Cr-51 and Fe-

59. For Cr-51 and Fe-59, an investigation was undertaken when the coefficient of variation exceeded the values shown on Table 3-6 below:

<300 NA 25 Cr-51 NA >1000 25

>300 <1000 15

<80 NA 25 Fe-59

>80 NA 15

For air filters, concentration units are pCi/filter. For all other media, concentration units are pCi/liter (pCi/1).

As required by ODCM 4.1.3.3 and 7.1.2.3, a summary of the results of the GPCEL's participation in the ICP is provided in Table 3-7 for:

gross beta and gamma isotopic analyses of an air filter

gamma isotopic analyses of milk samples

gross beta, tritium and gamma isotopic analyses of water samples The 2019 analyses included tritium, gross beta and gamma emitting radio-nuclides in different matrices. The attached results for all analyses were within acceptable limits for accuracy (less than 15% coefficient of variation and less than 3.0 normalized deviations, except for Cr-51 and Fe-59, which are outlined in Table 3-6).

PLANT VOGTLE 3.8 Groundwater To ensure compliance with NEI 07-07 (Industry Ground Water Protection Initiative - Final Guidance Document), Southern Nuclear developed the Nuclear Management Procedure, Radiological Groundwater Protection Program. The procedure contains detailed site-specific monitoring plans, program technical bases, and communications protocol (to ensure that radioactive leaks and spills are addressed and communicated appropriately). In an effort to prevent future leaks of radioactive material to groundwater, SNC plants have established buried piping and tanks inspection programs. No changes were made to the Groundwater Protection Program in 2019.

Plant Vogtle maintained the following wells (Table 3-8), which were sampled at a frequency that satisfied the requirements of NEI 07-07. The analytical results for 2019 were all within regulatory limits specified within this report. Table 3-9 contains the results of the Groundwater Protection Program tritium results (in pCi/L).

4.2 Savannah River Survey A desktop survey of the Savannah River downstream of the plant for approximately 100 miles (approximately river miles 44. 7 to 151.2} was conducted to identify any new withdrawal of water from the river for drinking, irrigation, or construction purposes. No new usage was identified in 2019 from databases maintained by Georgia or South Carolina. These results were verified with 2019 VEGP Annual Radiological Environmental Operating Report 33I Page

PLANT VOGTLE both the Georgia Department of Natural Resources and the South Carolina Department of Health and Environmental Control (SC DEHEC). Each of these agencies confirmed that no water withdrawal permits for drinking, irrigation, or construction purposes had been issued for this stretch of the Savannah River.

4.3 Meteorological Report Summary The meteorological tower data collected throughout the year is analyzed and compared to previous results by a third-party consultant. For 2019, the meteorological tower data were comparable to previous years, as related to precipitation amounts (44.95") and wind direction (from west-southwest at 10m, from the west at 60m). Therefore, no changes to REMP monitoring locations are warranted.

2019 VEGP Annual Radiological Environmental Operating Report 341 Page

PLANT VOGTLE 5 CONCLUSIONS This report has confirmed SN Cs conformance with the requirements of Chapter 4 of the ODCM and the objectives were to:

1) Determine the levels of radiation and the concentrations of radioactivity in the environs and;

2) Assess the radiological impact (if any) to the environment due to the operation of the VEGP.

Based on the 2019 activities associated with the REMP, SNC offers the following conclusions:

Samples were collected and there were no deviations or anomalies that negatively affected the quality of the REMP

Land use census and river survey did not reveal any significant changes

Analytical results were below reporting levels

These values were consistent with historical results, which indicate no adverse radiological environmental impacts associated with the operation of VEGP 2019 VEGP Annual Radiological Environmental Operating Report 35 I Page
