SUMMARY

January 1 -December 31, 2018 Docket Nos. 50-244 The Radiological Environmental Monitoring Program (REMP) is a comprehensive surveillance program, which is implemented to assess the impact of site operations on the environment and compliance with 10 CFR 50 Appendix I and 40 CFR 190. Samples are collected from the aquatic and terrestrial pathways applicable to the site. The aquatic pathways include Lake Ontario fish, surface waters, groundwater, and lakeshore sediment.

The terrestrial pathways include airborne particulate and radioiodine, milk, food products, and direct radiation.

Results of the monitoring program for the 2018 operational period for R.E. Ginna Nuclear Power Plant are included in this report. This report presents a synopsis of the REMP (Table 1), summary of the detectable activity analytical results (Table 2), sampling locations (Appendix A), compilation of the analytical data (Appendix B), results of the Quality Assurance Program (Appendix C), and results of the Land Use Survey (Appendix D). Interpretation of the data and conclusions are presented in the body of this report. The results of the REMP verify that the effluent releases did not impact the environment with a measurable concentration of radioactive materials and/or levels of radiation that are higher than expected.

The 2018 results for all pathways sampled were consistent with the previous five-year historical results and exhibited no adverse trends. The results of the REMP continue to demonstrate that the operation of the plant does not result in a measurable dose to a member of the general population, or adversely impact the environment as a result of radiological effluents.

The program continues to demonstrate that the dose to a member of the public, as a result of the operation of R.E. Ginna Nuclear Power Plant, remains significantly below the federally required dose limits specified in 10 CFR 20 and 40 CFR 190.

2.1 INTRODUCTION

Station Description January 1 -December 31, 2018 Docket Nos. 50-244 The R.E. Ginna Nuclear Power Plant (Ginna), owned by Exelon Generation, is an operating nuclear generating facility consisting of one pressurized water reactor. Ginna achieved criticality in September 1969 and commenced commercial operation in July 1970. The location of the plant in relation to local metropolitan areas is depicted in Appendix A, Figure A-1. 2.2 Program Description and Background The Annual Radiological Environmental Operating Report (AREOR) is published in accordance with Section 8.0 of the Offsite Dose Calculation Manual (ODCM, Ref. 1) and the Plant's Technical Specifications (Ref. 2). This report describes the REMP, and its implementation as required by the ODCM. The environmental surveillance data collected during this reporting period were compared with that generated in previous periods whenever possible to evaluate the environmental radiological impact of the R.E. Ginna Nuclear Power Plant. Results of the monitoring program for the pre-operational and previous operational periods through 2017 have been reported in a series of previously released documents.

The REMP is implemented to measure radioactivity in the aquatic and terrestrial pathways.

The aquatic pathways include Lake Ontario fish, surface waters, groundwater, and lakeshore sediment.

Measurement results of the samples representing these pathways contained only natural background radiation or low concentrations of Cs-137 resulting from past atmospheric nuclear weapons testing. Terrestrial pathways monitored included airborne particulate and radioiodine, milk, food products, and direct radiation.

2.3 Program Objectives The objectives of the REMP for the R.E. Ginna Nuclear Power Plant are: a. Measure and evaluate the effects of plant operation on the environment.

b. Monitor background radiation levels in the environs of the Ginna site. c. Demonstrate compliance with the environmental conditions and requirements of applicable state and federal regulations, including the ODCM and 40 CFR 190. d. Provide information by which the general public can evaluate environmental aspects of the operation of R.E. Ginna Nuclear Power Plant. 2 ___J

3. 3.1 PROGRAM DESCRIPTION Sample Collection and Analysis January 1 -December 31, 2018 Docket Nos. 50-244 The locations of the individual sampling stations are listed in Table A-1 and shown in Figures A-2 and A-3. All samples were collected and analyzed by Exelon personnel or its contractors in accordance with Ginna procedures (Ref. 3).

During 2018, 1348 samples were collected for analysis by gross beta counting, tritium, and/or gamma spectroscopy.

These included 89 surface water samples, 16 fish samples, 6 sediment samples, 624 air particulate samples, 312 air iodine samples, 28 vegetation samples, 38 milk samples, 71 groundwater samples, and 164 dosimeter measurements.

Deviations from the REMP sampling schedule are described in section 3.5. This monitoring program satisfied the minimum number of samples required by the ODCM for all pathways.

R.E. Ginna Nuclear Power Plant's Chemistry personnel collected all REMP samples. Analysis was performed at either Ginna's onsite laboratory (groundwater samples), Environmental Dosimetry Company in Sterling Massachusetts (direct radiation samples), or Exelon Industrial Services -Ft. Smallwood Environmental Laboratory in Baltimore, Maryland (surface and drinking water, aquatic organisms, shoreline sediment, air particulate filters, air iodine, and vegetation samples).

A summary of the content of the REMP and the results of the data collected for indicator and control locations are provided in Tables 1 and 2. 3.2 Data Interpretation Many results in environmental monitoring occur at or below the minimum detectable activity (MDA). In this report, all results below the relevant MDA are reported as being "not detected." Typical MDA values are listed in Appendix B, Table B-10. 3.3 Quality Assurance Program Appendix C provides a summary of Exelon Industrial Services (EIS) -Ft. Smallwood Environmental Laboratory's quality assurance program for 2018. It consists of Table C-1, which represents a compilation of the results of the EIS -Ft. Smallwood Environmental Laboratory's participation in an inter-comparison program with Environmental Resource Associates (ERA) located in Arvada, Colorado and Analytics, Inc. located in Atlanta, Georgia. Table C-2 compiles the results of the Exelon Industrial Services Ft. Smallwood Laboratory's participation in a split sample program with Teledyne Brown Engineering located in Knoxville, Tennessee.

Table C-3 identifies a list of typical MD As achieved by Teledyne Brown for Gamma Spectroscopy.

All the EIS -Ft. Smallwood Environmental Laboratory results contained in Table C-1 agree with the inter-comparison laboratory results within the range of +/-2 cr between the analytical values or are in agreement with the ranges established in the NRC Resolution Test Criteria.

3 January 1 -December 31, 2018 Docket Nos. 50-244 All the results contained in Table C-2 agree within the range of +/-2 cr of each other with their respective Ft. Smallwood Environmental Laboratory original, replicate and/or Teledyne Brown Engineering's split laboratory samples. 3.4 Land Use Survey In September 2018, Ginn a staff conducted a Land Use Survey to identify the location of the nearest milk animal, the nearest residence, and the nearest garden greater than 500 square feet in each of the nine sectors within a five-mile radius of the power plant. The Land Use Survey is conducted in accordance with Ginna procedures (Ref. 4). If changes are noted in the annual Land Use Survey, alterations to Ginna's REMP program would be made to ensure sampling practices cover these new areas of potential public exposure.

The position of the nearest residence and garden and animals producing milk for human consumption in each sector is provided in Appendix D, Table D-1. Over the past year, the following land use observations were made within a 5-mile radius of the power plant:

The nearest residence remains in the SSE sector, approximately 610 meters from the reactor.

Single-family home/ senior housing subdivision/

development construction was observed near the plant on LaFrank Drive (Ontario), and South of Route 104 near Tops Plaza (Ontario).

Lake Front Estates and Summer Lake subdivisions continue to expand along with the southeast corner of Lake Road and Slocum Road.

Other single-family home construction was observed sporadically within 5-miles of the plant.

A new 120-acre commercial hydroponic farm continues construction on the east-end of Timothy Lane (North of Route 104). During 2018, this facility did not become operational.

Commercial fishing information was collected from the New York State Department of Environmental Conservation (NYSDEC) which shows activity only in the Eastern basin of Lake Ontario. Commercial fishing operations have not changed in the last five-years and no commercial fishing takes place within 5-miles of Ginna.

No new agricultural land use was identified.

No new food producing facilities were identified as the commercial hydroponic farm is not currently growing produce. *

No new milk producing animals were identified.

4 3.5 Program Exceptions January 1 -December 31, 2018 Docket Nos. 50-244 The reportable items in the Annual Environmental Radiological Operating Report under procedure CHA-RETS-VARIATION are as follows:

On 4/6/18, Environmental Sample Station ES3 (Air Sample Station) was found to be out of service following a significant wind event. The volume collected during this time period was 86.5 m3, which does not meet the minimum required sample volume for the sample period.

On 4/19/18, TLD16 (SW Corner of orchard, approximately 3000' West of plant, approximately 200' North of Lake Road) was found on the ground during quarterly TLD changeout.

TLD 16 was changed out for the quarter. TLD64 (Westside of direct road, adjacent to orchard) which is near TLD16 did not experience any sampling anomalies.

The cause of TLD 16 being on the ground was the storm which brought high winds on 3/2/18.

On 4/19/18, TLD32 (Woodard Road at County Line Road, pole at Northwest corner) was found remounted on an incorrect pole facing the incorrect direction (away from reactor center-line) during quarterly TLD changeout.

This TLD is located between TLD3 l (Lake Road, pole 20' North of road, 500' East of Salt Road) and TLD33 (County Line Road at RR tracks, pole approximately 100' East along tracks). The cause of TLD32 being remounted on the wrong pole in the wrong direction was the storm which brought high winds on 3/2/18.

On 4/27/18, Environmental Sample Station ES3 (Air Sample Station) was relocated from GPS coordinates (43.27643, -77.30366) to GPS coordinates (43.27667, -77.30646) due to an ongoing power supply issue. Both*locations remain in the same meteorological sector. For the sampling period from 4/23/18 -4/27 /18, the sample collection station collected 41.9 m 3 of sample. After relocation where the sample period was from 4/27/18 to 4/30/18, 133.6 m 3 of sample was collected.

The same particulate filter was used for both sampling periods. This volume meets the minimum amount required, but the change in location has been noted as an exception.

On 12/3/18, Environmental Sample Station ES6 (Air Sample Station) was found to be out of service. The volume collected during this time was 69.0 m3, which does not meet the minimum required sample volume for the sample period. 3.6 Corrections to Previous Reports There are no corrections necessary to any previously submitted Annual Radiological Environmental Operating Report (AREOR). 5

4. RESULTS AND DISCUSSIONS January 1 -December 31, 2018 Docket Nos. 50-244 All environmental samples collected during the year were analyzed in accordance with Exelon analytical procedures (Ref. 5). The analytical results for this reporting period are presented in Appendix B and the detectable activity results are also summarized in Table 2. For discussion purposes, the analytical results are divided into five categories:

Aquatic Environment, the Atmospheric Environment, the Terrestrial Environment, Direct Radiation, and Groundwater.

4.1 Aquatic Environment The aquatic environment surrounding the plant was monitored by analyzing samples of surface and drinking water, Lake Ontario fish, and shoreline sediment.

These samples were obtained from various sampling locations near the plant. 4.1.a Surface and Drinking Water Monthly composite samples are collected from Lake Ontario at an upstream control location (Monroe County Water Authority

-Sho.remont) and a downstream indicator location (Ontario Water District Plant -OWD) and analyzed for gross beta activity (Table B-1). A grab sample of Deer Creek is collected and analyzed monthly for gross beta activity (Table B-1 ). Lake Ontario is a primary indicator for sampling due to the close proximity to the station as well as the Lake providing recreational activities which could be a means of public exposure.

Additionally, liquid releases from the station enter Lake Ontario waters, which leads to sampling of this environment, in all its forms, to be a priority.

In 2018, the gross beta averages for the upstream Lake Ontario monitoring locations (controls) and downstream Lake Ontario monitoring locations (indicators) were 2.89 pCi/Liter and 2.69 pCi/Liter, respectively.

Gross beta analysis of the monthly composite samples showed no statistically significant difference in activity between the control and indicator locations that would indicate plant related activity higher than background.

The average gross beta concentration seen in the Mill Creek samples (control) and the Deer Creek (indicator) samples were 3.96 pCi/Liter and 4.27 pCi/Liter, respectively.

Results from Deer Creek (indicator) and Mill Creek (control) are higher than other surface water samples within the REMP program due to naturally occurring radiological daughter products from radon within the soil being introduced into the samples. These naturally occurring radiological daughter products would exist in this environ at these same levels even if Ginna had never been built. Gross beta analysis of the samples showed no statistically significant difference in activity between the control and indicator locations that would indicate plant related activity higher than background.

Gamma isotopic analysis is performed on each monthly composite sample. These are listed in Table B-1 and are separated by source of sample. During 2018, no sample results indicated detection of gamma activity above MDA. 6 January 1 -December 31, 2018 Docket Nos. 50-244 Tritium analysis was performed on all water samples on a monthly basis. Composites are made from the weekly samples and a portion filtered to remove interferences for analysis by beta scintillation.

During 2018, no surface water or drinking water sample results indicated detectable tritium activity.

4.1.b Aquatic Organisms Indicator fish are caught in the vicinity of the Discharge Canal and analyzed for radioactivity from liquid effluent releases from the plant. The fish are filleted to represent that portion which would normally be eaten and represents the likely pathway for human exposure.

Additional fish are caught more than 15 miles away to be used as control samples and are prepared in the same manner. At a minimum, four different edible species of fish are analyzed during each half-year from the indicator and background locations.

Fish are caught by R;E. Ginna Nuclear Power Plant Chemistry personnel and are analyzed by gamma spectroscopy after being held for periods typically less than two weeks to keep the LLD value for the shorter half-life isotopes realistic.

Detection limits could also be affected by small mass samples, ( < 2000 grams), in some species. gamma isotopic concentrations (pCi/kilogram wet) are listed in Table B-2. During 2018, none of the indicator samples indicated activity other than naturally occurring radionuclides.

4.1.c Shoreline Sediment Samples of shoreline sediment are taken upstream (Town of Greece near Slater Creek) and downstream (Near the Ontario Water District) of R.E. Ginna Nuclear Power Plant. The control sample is typicaJ of the lake bottom, rich in mollusk shells and rocky particulate.

These samples are analyzed for radionuclides that a member of the public would be expected to encounter during swimming and wading activities.

Similarly, indicator samples are collected at the Bear Creek boat dock as this is another recreational area accessible to the public. Results of the gamma isotopic analysis for sediment are included in Table B-3. During 2018, all sediment samples indicated that gamma emitters were below detection limits. 4.2 Atmospheric Environment Radioactive particles in air are collected by drawing approximately one standard cubic foot per minute (SCFM) through a two-inch diameter particulate filter. The volume of air sampled is measured by a dry gas meter and corrected for the pressure drop across the filter. The filters are changed weekly and allowed to decay for three days prior to counting to eliminate most of the natural radioactivity such as the short half-life decay products of radon. The decay period is used to give a more sensitive measurement of long-lived man-made radioactivity.

7 January 1 -December 31, 2018 Docket Nos. 50-244 A ring of six sampling stations is located on the plant site from 180 to 440 meters from the reactor centerline near the point of the maximum annual average ground level concentration, one additional sampling location is located on-site at 770 meters, and two others offsite at approximately seven miles. In addition, there are three sampling stations located approximately seven to 16 miles from the site that serve as control stations.

The arrangement of air sampling stations in .concentric rings around the station would ensure the environment would be appropriately monitored if a radiological release were to occur. See Figure A-2 and Figure A-4. 4.2.a Air Iodine Radioiodine cartridges are placed at six locations.

These cartridges are changed and analyzed each week. No positive analytical results were found on any sample. A list of values for these cartridges is given in Table B-4. 4.2.b Air Particulate Filters The major airborne species released as gaseous effluents are noble gases and tritium. Most of this activity is released in a gaseous form; however, some radioiodine is released as airborne particulate and some of the particulate activity is due to short lived noble gas decay products.

Tables B-5 provides a list of gross beta analysis values for the on"'site sample stations.

Table B-6 is a list of gross beta analysis values for the off-site sample stations.

Based on the weekly comparisons, there was no statistical difference between the control and indicator radioactive particulate concentrations.

The average for the control samples (i.e., offsite sampling locations) was 0.023 pCi/m 3 and the averages for the indicator samples (i.e., onsite sampling locations) was 0.022 pCi/m 3 for the period of January to December 2018. Maximum weekly concentrations for all control stations and all indicator stations were 0.047 pCi/m 3 and 0.048 pCi/m 3 , respectively.

The particulate filters from each sampling location were saved and a 13-week composite was made. A gamma isotopic analysis was performed for each sampling location and corrected for decay. No positive analytical results were found on any sample. The results of these analyses are listed in Tables B-7. 4.3 Terrestrial Environment Crops are grown on the plant property in a location with a highest off-site meteorological deposition parameter, and samples of the produce are collected at harvest time for analysis.

Control samples are purchased from farms greater than 10 miles from the plant. 4.3.a Vegetation There was no indication in the vegetation samples contained activity greater than naturally occurring background levels. Both onsite (indicator) and offsite (control) vegetation samples are rinsed prior to sampling as this is the expected behavior to be exhibited by a member of the public prior to consuming any produce. Analyses revealed that there was no difference in the 8 January 1 -December 31, 2018 Docket Nos. 50-244 radiological activity observed in the indicator and control sampling locations.

Gamma isotopic data is provided in Table B-8. 4.3.b Milk Although there are no indicator dairy herds located within five miles from the plant, Ginna has elected to continue sampling the milk pathway as a supplemental sample to satisfy this potential exposure pathway to a member of the public. This pathway is specific to gaseous radiological releases from Ginna station that could deposit onto the grazing pastures of dairy farms. When. these grazing cows are milked, any potential radiological exposure received by the cow could enter the human pathway. In 2018, milk samples were collected monthly during November through May from the indicator farm and biweekly during June through October. Samples are collected twice as frequently in the summer as the likelihood of cows grazing and not consuming stored feed is higher during this time. A control farm sample is taken for each monthly sample and once during each biweekly period. The milk is analyzed for Iodine-131 and also analyzed by gamma spectroscopy.

During 2018, no samples indicated I-131 activity above detection levels. There was no difference in the radiological activity observed in the indicator and control sampling locations.

Table B-9 provides a listing of all samples collected and analytical results. 4.4 Direct Radiation Dosimeters are placed as part of the environmental monitoring program. 41 dosimeter badges are currently placed in four rings around the plant. These rings range from less than 1,000 feet to 15 miles and have been dispersed to give indications in each of the nine land-based sectors around the plant should an excessive release occur from the plant. Badges are changed and read after approximately three months exposure.

Each direct radiation sampling location is described in Table A-1 and identified in Figure A-2. Direct radiation readings at locations

7 and #13 are influenced by their close proximity to the site's Independent Spent Fuel Storage Installation (ISFSI) and will normally read slightly higher than other locations.

Environmental Station 13, the closest sampling location.to the ISFSI, received an average quarterly dose of 18.4 mRem during 2018. All onsite indicators averaged 12.2 mRern/qtr.

For the year of 2018, the average, minimum, and maximum exposure readings was as follows: Monitoring Groug Average Min. Max (rnrern/gtr) (rnrern/gtr) (rnrern/gtr)

Onsite Indicators 12.2 8.8 19.2 Site Boundary Indicators 12.1 9.2 15.1 Offsite Indicators 11.1 8.1 13.2 Control Locations 10.5 8.8 11.8 9 January! -December 31, 2018 Docket Nos. 50-244 40 CFR 190 requires that the annual dose equivalent not exceed 25 millirem to the whole body of any member of the public. The average quarterly exposure observed at the control monitoring stations was used to determine the background level (equivalent to 10.5 millirems monthly or 42.0 millirem annually), while the highest total annual dosimeter reading at an individual site boundary environmental monitoring location (55.2 millirem) was observed at Environmental Monitoring Station #64. The difference in these values determines the maximum possible direct radiation dose expo s ure to an offsite member of the public. Accordingly, the hypothetical maximum direct radiation dose exposure to the public for 2018 was determined to be 13.2 millirem by subtraction of average background from the maximum annual indicator site. Figure 1 represents the hypothetical maximum direct radiation dose exposure over the past fifteen years. As noted in the 2011 Annual Radiological Environmental Operating Report (AREOR), an apparent upward trend with the reported average annual direct radiation dose was identified.

It was noted that the average annual direct dose to an off site member of the public had increased 2-3 mRem since 2008 (Condition Report CR-2012-001275). Ginna staff evaluated this apparent trend and concluded the elevated dosimeter readings were likely the result of increased onsite hold time s after the do s imeter s had been collected.

In 2018, Ginna staff collected and analyzed samples collected from a total of 14 groundwater monitoring wells:

GWOl: Warehouse Access Road (Control)

GW03: Screenhouse West, South Well

GW04: Screenhouse West, North Well

GW05: Screenhouse East, South (15.5')

GW06: Screenhouse East, Middle (20.0')

GW07: Screenhouse East, North (24.0')

GW08: All Volatiles Treatment Building

GWlO: Technical Support Center, South

GWll: Contaminated Storage Building, SE (24.0')

GW12: West of Orchard Access Road

GW13: North of Independent Spent Fuel Storage Installation (ISFSI)

GW14: South of Canister Preparation Building

GW15: West of Manor House

GW16: Southeast of Manor House Tritium is sampled for at nuclear facilities due to it the migration capabilities of tritium. Essentially, tritium, when in an aqueous form, flows like water and can be found in surface water, groundwater, and atmospheric environs due to evaporative processes found in nature. Nuclear stations place a sensitivity on detecting tritium in the environment as it is an efficient marker to show if radioactivity has been introduced off-site.

Groundwater samples are analyzed for tritium to a detection limit of 500 pCi/L, and for gamma emitting radionuclides to the environmental LLDs. The analytical results for groundwater monitoring well samples collected during 2018 are presented in table B-13. No positive tritium results were identified in any of the groundwater monitoring wells during 2018. 4.6 Summary and Conclusion Operation of the R.E. Ginna Nuclear Power Plant produced radioactivity and ambient radiation levels significantly below the limits of the ODCM and 40 CFR 190. The analytical results from the Radiological Environmental Monitoring Program indicate the operation of the R.E. Ginna Nuclear Power Plant had no measurable radiological impact on the environment or measurable build-up of plant-related radionuclides in the environment.

The results also indicate operation of the plant did not result in a measurable radiation dose to the general population above natural background levels. Additionally, the 2018 results are consistent with data for the past seven years and exhibited no detectable increases or adverse trends. Further explanation on REMP data can be found in Appendix E. 11

< 397 < 7.lOE-09 1 Gamma analysis is performed on a quarterly basis for groundwater monitoring well results. Groundwater monitoring wells GW03 and GW08 are sampled monthly due to their location being important for early detection of any tritium within the environment.

Groundwater Monitoring Well GWl2 did not return a sample on 9/7/2018 as there was no groundwater in the monitoring well. 52 APPENDIXC Quality Assurance Program Summary of Appendix C Content: January I -December 31, 2018 Docket Nos. 50-244 Appendix C is a summary of Exelon Industrial Services (EIS) Laboratory's quality assurance program. Table C-1 is a compilation of results from the interlaboratory comparison program between EIS Laboratory, Environmental Resource Associates (ERA) located in Arvada, Colorado and Eckert and Ziegler Analytics Inc. located in Atlanta, Georgia. Table C-2, is a compilation of the results of the EIS laboratory's quality assurance analysis of laboratory duplicates and split samples with Teledyne Brown Engineering located in Knoxville, Tennessee.

Table C-3, is a list of typical MD As achieved by Teledyne Brown for Gamma Spectroscopy.

All the EIS Laboratory's results contained in Table C-1 generally agree with the intercomparison laboratory's results within the range of +/-2 cr of each other. In addition, all the sets of intercomparison results in the table are in full agreement when they were further evaluated using the NRC Resolution Test Criteria[!].

The uncertainties for the EIS laboratory's results and Analytics' results are +/-2cr while the ERA laboratory's uncertainty is based on USEPA guidelines[2].

All the results contained in Table C-2 agree within the range of +/-2cr of each other with their respective EIS Laboratory original, replicate and/or Teledyne Brown Engineering's split laboratory samples. The comparison of a soil sample SFS3 collected on 5/29/18 was in full agreement with the split laboratory sample positive for Cs-137 at 77.8+/-35.3 pCi/kg and 106+/-53.6 pCi/kg respectively.

The replicate analysis showed no Cs 137 observed however the MDA value of l lOpCi/kg was within the acceptable range of the positive results of the original and split sample in accordance with the NRC Radiochemical Acceptance Criteria for Split Samples [1]. Other samples whose nature generally preclude sample splitting are marked "**" in the Split Analysis column. * [1] NRC Inspection Manual, Inspection Procedure 84750, March 15, 1994 [2] National Standards for Water Proficiency Testing Studies Criteria Document, December 1998 53 Table January 1 -December 31, 2018 Docket Nos. 50-244 TABLE OF CONTENTS -ANALYTICAL RESULTS Title Page C-1 Results of Participation in Cross Check Program ............................................................................

A detailed description of the Land Use Survey is given in a separate attachment.

The position of the nearest residence and garden and animals producing milk for human consumption in each sector out to five miles is given in the above Table D-1. Changes from Previous Years: The nearest residence remains in the SSE sector, approximately 610 meters from the reactor. Single-family home/ senior housing subdivision/

d~velopment construction was observed near the plant on LaFrank Drive (Ontario), and South of Route 104 near Tops Plaza (Ontario).

Lake Front Estates and Summer Lake subdivisions continue to expand along with the southeast corner of Lake Road and Slocum Road. Other single-family home construction was observed sporadically within 5-miles of the plant. A new 120-acre commercial hydroponic farm continues construction on the east-end of Timothy Lane (North of Route 104). During 2018, the facility did not become operational.

Commercial fishing information was collected from the New York State Department of Environmental Conservation (NYSDEC) which shows activity only in the Eastern basin of Lake Ontario. Commercial fishing operations have not changed in the last five-years and no commercial fishing takes place within 5-miles of Ginna. No new agricultural land use was identified.

No new food producing facilities were identified as the commercial hydroponic farm is not currently growing produce. No new milk producing animals were identified.

Milk Animal Locations Schultz Farm -450 Boston Road, Ontario NY Field Craft Farm (supplemental sample)-6747 Salmon Creek Road, Williamson NY No new milk producing animals were identified in the 2018 survey. 68 APPENDIXE January 1 -December 31, 2018

Docket Nos. 50-244 Interpretations and Graphical Representations Summary of Appendix E Content: To better illustrate that the continued operation of the RE. Ginna Nuclear Power Plant (Ginna) has no statistically significant impact on the surrounding environment, Appendix E contains the results of the last seven years of Radiological Environment Monitoring Program (REMP) data. Where applicable (when analytical results produced a measured numerical value), trends have been produced to show values that have been observed in the various environs surrounding Ginna. A discussion of these results will accompany each series of trends to enhance understanding of the REMP program. 69 Table TABLE OF CONTENTS -January 1 -December 31, 2018 Docket Nos. 50-244 INTERPRETATIONS AND GRAPHICAL REPRESENTATIONS Title Page E-1 E-Series 1, Table B-1 (Gross Beta Values for Surface and Drinking Water) ....................

93 70 E-Series 1 January 1 -December 31, 2018 Docket Nos. 50-244 Table B-1 (Gross Beta Values for Surface and Drinking Water) Ginna's Offsite Dose Calculation Manual (ODCM) is written in accordance with specifications contained within 10 CFR 20 and the Branch Technical Position document published by the NRC in 1979. This document specifies Gross Beta in Surface Water samples to be detected to a Lower Limit of Detection (LLD) of 4 pCi/1. Since that time, detection capabilities have improved which allow values to be measured lower than the required 4 pCi/1. The trends below include the Gross Beta averages (from 2012-2018) for Ginna's surface water samples (Circ-In, Circ -Out, MCWA, Deer Creek, Mill Creek, OWD, and Webster).

An elevated Gross Beta result inconsistent with the trend would indicate radionuclides in the sample which would require further analysis.

From 2012 through 2018, no such results have been received from Ginna' s REMP program. Results from Deer Creek (indicator) and Mill Creek (control) are higher than other surface water samples within the REMP program due to naturally occurring radiological daughter products within the soil being introduced into the samples. It is worth noting that these naturally occurring radiological daughter products would exist in this environ at these same levels even if Ginna had never been built. These samples are obtained to evaluate the potential for public exposure due to the surface water (Mill Creek, Circ-In, Circ-Out, and Deer Creek) and drinking water pathway (Monroe County Water Authority, Webster Water, and Ontario Water District).

These locations are chosen as a member of the public is most likely to encounter water which has left Ginna property via these sample streams. Trend "B-1 Control and Indicator Averages (2012-2018) shows the relationship between the control samples (Mill Creek, MCWA, and Webster Water) and the indicator samples (Circ-In, Circ-Out, Deer Creek, and OWD). This trend illustrates that there is no statistically significant difference between control and indicator samples for Gross Beta in Surface water from 2012-2018. 71 January 1 -December 31 , 2018 Docket No s. 50-244 B-1 Control and Indicator Averages (2012-2018)

Ginna' s Off site Dose Calculation Manual (ODCM) is written in accordance with specifications contained within 10 CFR 20 and the Branch Technical Position document published by the NRC in 1979. This document specifies Gross Beta in Air Particulate samples to be detected to a Lower Limit of Detection (LLD) of 1.0 X 10-2 pCi/m 3. Accordingly, analyses performed as part of the REMP at Ginna satisfy this requirement.

The trends below include the Gross Beta averages (from 2012-2018) for Ginna's air particulate samples (Station-02 through Station-13).

An elevated Gross Beta result inconsistent with the trend would indicate radionuclides in the sample which would require further analysis.

From 2012 through 2018, no such results have been received from Ginna's REMP program. Sampling locations (Station-02 through Station-13) are noted below, and their classification as either a control or an indicator.

These locations were selected to show areas where breathable air, which has the potential to be in communication with air released from Ginna, could lead to public exposure.

Some locations (such as Station-08, Seabreeze and Station-12, Sodus Point) are sampled due to recreational activities in the area and their associated sensitivity.

E-Series 3 Table B-12 (Direct Radiation)

January 1 -December 31, 2018 Docket Nos. 50-244 40 CFR 190 requires that the annual dose equivalent not exceed 25 millirem to the whole body of any member of the public. The average quarterly exposure observed at the control monitoring stations was used to determine the background level (equivalent to 10.5 millirems monthly or 42.0 millirem annually), while the highest total annual dosimeter reading at an individual site boundary environmental monitoring location (55.2 millirem) was observed at Environmental Monitoring Station #64. The difference in these values determines the maximum possible direct radiation dose exposure to an offsite member of the public. Accordingly, the hypothetical maximum direct radiation dose exposure to the public for 2018 was determined to be 13.2 millirem by subtraction of average background from the maximum annual indicator site. The trends below include the average quarterly exposure (in millirem, mR) for Ginna's direct radiation monitoring locations.

This quarterly average is averaged for the year to facilitate trending.

Direct radiation is the measurement that a member of the public would experience due to being near a source of radioactivity, such as a nuclear power plant in addition to natural sources. These natural sources are present throughout the environment (examples include being near bedrock rich in granite, being in the presence of the sun, radon gas emerging from layers of earth, etc.) and the direct radiation measurement Ginna collects is to determine if there is any statistically significant additional exposure from the operations of the nuclear facility.

Trend "B-12 Control and Indicator Averages (2012-2018) shows the relationship between the control samples (TL-08, TL-10, TL-12, TL-25 -TL-30) and the indicator samples (TL-02-TL 07, TL-11, TL-13 -TL-24, TL-31 -TL-40, TL-63, and TL-64). This trend illustrates that there is no statistically significant difference between control and indicator samples for direct radiation exposure in millirem from 2012-2018.

Ginna's Offsite Dose Calculation Manual (ODCM) is written in accordance with specifications contained within 10 CFR 20 and the Branch Technical Position document published by the NRC in 1979. This document specifies Tritium and Gamma in Groundwater samples to be detected to a Lower Limit of Detection (LLD) of 2,000 pCi/1. Since that time, detection capabilities have improved which allow values to be measured lower than the required 2,000 pCi/1 and Ginna measures tritium concentration down to a LLD of 500 pCi/1. The trends below include the tritium averages (from 2012-2018) for Ginna's groundwater samples (GWO I, GW03 -GW08, GW-10 -GW 16). A tritium value of greater than 20,000 pCi/1 would indicate radionuclides in the sample which would require further analysis and offsite reporting.

From 2012 through 2018, no such results have been received from Ginna's REMP program. Tritium (H-3) is a radioactive form of Hydrogen and, when detected in the environment at levels (greater than 2,000 pCi/1, can be an indication that plant effluents may have been introduced into the environment.

Tritium is sampled for at nuclear facilities due to its exposure capabilities for members of the public. Essentially, Tritium, when in an aqueous form, flows like water and can be found in surface water, groundwater, and atmospheric environs due to evaporative processes found in nature. Nuclear stations place a sensitivity on detecting Tritium in the environment as it is an efficient marker to show if radioactivity has been introduced off-site. All results shown below are less-than values (<LLD) excluding the sample result for groundwater monitoring well GW04 from 1/30/2013, which the result was 2,520 pCi/1. This higher than normal value was the result of atmospheric recapture of gaseous tritium which accumulated in snow located around the facility.

As this snow melted during this sampling period, this recaptured tritium was introduced into the groundwater and captured via our groundwater sampling program. It is worth noting that this value of 2,520 pCi/1 is roughly 8-times lower than the reportable limit of 20,000 pCi/1. Additionally, groundwater monitoring well GW 14 on 3/11/2014 was counted to an LLD of 2,000 pCi/1 rather than the LLD of 500 pCi/1. Actual result was a less than value of< 1,950 pCi/1. Subsequent samples were collected to ensure there was no detectable tritium in the environment and these samples returned values of Jess than 500 pCi/1. Ginna classifies groundwater monitoring well GWOl (West of the station, "upstream" as the "control" location for sampling.

Due to the sampling frequencies of this program, it is difficult to graphically compare the control samples against the indicator samples. Since 2012, the average tritium concentration in control samples (Groundwater Monitoring Well GWOl) was< 452 pCi/1 whereas the average tritium concentration in indicator samples (Groundwater Monitoring Well GW-03 -GW08, GW 10-GW 16) was < 454 pCi/1. This result demonstrates that there is no statistically significant difference between control and indicator samples for Ginna's groundwater samples for the REMP. 93 2000 1800 1600 :::::. 1400 1200 C: *e 1000 :-e 800 600 400 2 00 ******* 0 1/1/2 01 2 2 000 1800 1600 :::::. 1400 1 2 00 C: *e 1000 *-5 800 'i: t-600 400 200 0 1/1/2012
