SUMMARY

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 2016 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 ofradiation that are higher than expected. The 2016 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 did not result in a significant 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 ofR.E. Ginna Nuclear Power Plant, remains significantly below the federally required dose limits specified in 10 CFR 20 and 40 CFR 190.

2. INTRODUCTION 2.1 Station Description 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 is published in accordance with Section 5.0 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 2015 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-13 7 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.

3. PROGRAM DESCRIPTION 3.1 Sample Collection and Analysis 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 2016, 1360 samples were collected for analysis by gross beta counting and/or gamma spectroscopy. These included 88 surface water samples, 17 fish samples, 5 sediment samples, 636 air particulate samples, 317 air iodine samples, 26 vegetation samples, 38 milk samples, 69 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 2016. 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 MDA's 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.

January 1 - December 31, 2016 Docket Nos. 50-244 All the results contained in Table C-2 agree within the range of +/-2 a 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 2016, Ginna 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). 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.

The Monroe County Water Authority (MCWA) completed construction of a new municipal water facility which began operation in 2014 and remains operational.

Single-family home construction was observed south of the plant on Ontario Center Road between Brick Church Road and Kenyon Road, Shoreline Subdivision, Summer Lake Subdivision, Morely Way, Lincoln Road, and Boston Road.

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

A new commercial plaza was constructed on the north side of Route 104 between Ontario Center Road and Knickerbocker Road.

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.

No new agricultural land use was identified.

. No new food producing facilities were identified.

No new milk producing animals were identified.

January 1 - December 31, 2016 Docket Nos. 50-244 3.5 Program Exceptions The reportable items in the Annual Environmental Radiological Operating Report under procedure CHA-RETS-VARIATION are as follows:

Maintenance was performed on the hour meter at Environmental Sample Station # 4 on 6/20/16 at which time they discovered the ground fault interrupter (GFI) had tripped.

Ginna staff reset the GFI once maintenance on the sample station was complete. For the sample period of 6/13/16-6/20/16, the unit collected 81.5 m 3 . The hour meter was out of service during this sampling period.

On 6/28/16, a compensatory grab sample was taken at the Monroe County Water Authority (MCWA) low lift station (Greece, New York) due to the loss of water supply to the sampler. The grab sample represents the sample period from 6/20/16-6/28/16.

On 11/14/16, The Monroe County Water Authority (MCWA) composite sampler was turned off by the municipality owners until the end of December 2016 due to chemical treatment operations. Compensatory weekly grab samples were taken at Slater Creek from 11/14/16-1/9/17.

3.6 Corrections to Previous Reports The 2015 AREOR did not include a reportable deviation from REMP sampling that occurred in February, 2015:

Due to hazardous environmental conditions and seasonal unavailability, Ginna personnel were not able to obtain the Deer Creek and Mill Creek supplemental surface water samples during February 2015. Sub-freezing conditions during the entire month of February did not allow for sampling to occur.

January 1 - December 31, 2016 Docket Nos. 50-244

4. RESULTS AND DISCUSSIONS 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 Band 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 - Shoremont) 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 ).

In 2016, the gross beta averages for the upstream Lake Ontario monitoring locations (controls) and downstream Lake Ontario monitoring locations (indicators) were 2.05 pCi/Liter and 1.87 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 4.16 pCi/Liter and 3.80 pCi/Liter, respectively.

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 2016, no sample results indicated detection of Gamma activity.

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 2016, no surface water or drinking water sample results indicated detectable tritium activity.

6

January 1 - December 31, 2016 Docket Nos. 50-244 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. 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 offish 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 2016, none of the indicator samples indicated activity other than naturally occurring radionuclides. There was no significant difference in the radiological activity in the indicator and control sampling locations.

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.

Results of the gamma isotopic analysis for sediment are included in Table B-3. During 2016, all sediment samples indicated that gamma emitters were below detection limits. There was no difference in the radiological activity observed in the indicator and control sampling locations.

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 oflong-lived man-made radioactivity.

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. See Figure A-2 and Figure A-4.

7

January 1 - December 31, 2016 Docket Nos. 50-244 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 from the plant 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 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 0.021 pCi/m3 and the averages for the indicator samples (i.e., onsite sampling locations) was 0.021 pCi/m3 for the period of January to December 2016. Maximum weekly concentrations for all control stations and all indicator stations were 0.037 pCi/m3 and 0.045 pCi/m3, 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. There was no difference in the radiological activity observed in the indicator and control sampling locations. Gamma isotopic data is provided in Table B-8.

8

January 1 - December 31, 2016 Docket Nos. 50-244 4.3.b Milk There was one indicator dairy herd located within five miles from the plant in 2016. Milk samples are collected monthly during November through May from the indicator farm and biweekly during June through October. 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 2016, 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 2016. All onsite indicators averaged 12.9 mRem/qtr.

For the year of2016, the average, minimum, and maximum exposure readings was as follows:

Monitoring Groug Average Min. Max (mrem/qtr) (mrem/qtr) (mrem/qtr)

Onsite Indicators 12.9 8.4 20.5 Site Boundary Indicators 12.8 9.4 15.9 Offsite Indicators 11.9 8.9 15.4 Control Locations 11.1 8.6 14.1 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 11.1 millirems monthly or 44.4 millirem annually), while the highest total annual dosimeter reading at an individual site boundary environmental monitoring location (57.2 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 2016 was determined to be 12.8 millirem by subtraction of average background from the maximum annual indicator site.

Building

GW16: Southeast of Manor House GW15: West of Manor House Groundwater samples are analyzed for tritium to a detection limit of 500 pCi/L, and for gamma emitting radionuclides to the environmental LLDs. Due to dry summer conditions, samples were not collected from GW-12, GW-13, and GW-16 during the third quarter sampling period. The analytical results for groundwater monitoring well samples collected during 2016 are. presented in table B-13.

No positive tritium results were identified in any of the groundwater monitoring wells during 2016.

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 significant 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 2016 results are consistent with data for the past five years and exhibited no detectable increases or adverse trends.

January 1 - December 31, 2016 Docket Nos. 50-244 APPENDIXC Quality Assurance Program Summary of Appendix C Content:

Appendix C is a summary of Exelon Industrial Services (EIS) Laboratory's quality assurance program.

Table C-1 is a compilation ofresults from the inter-laboratory 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 oflaboratory duplicates and split samples with Teledyne Brown Engineering located in Knoxville, Tennessee. Table C-3, is a list of typical MDAs achieved by Teledyne Brown for Gamma Spectroscopy.

All the EIS Laboratory's results contained in Table C-1 generally agree with the inter-comparison laboratory's results within the range of +/-2 cr of each other. In addition, all the sets of inter-comparison results in the table are in full agreement when they were further evaluated using the NRC Resolution Test Criteria [1]. The uncertainties for the Constellation Energy 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 comparisons of two samples involving Cs-137 results: bottom sediment sample at WBS4 collected on 6/14/16 and soil at SFS5 collected on 9/26/16 were in full agreement. The original and replicate analysis of the bottom sediment sample at WBS4 collected on 6/14/16 agrees within +/-2 cr of each other.

Low level Cs-137 was observed in the comparison set for SFS5 collected on 9/26/16 in the original, duplicate and split lab sample. Results are in agreement within +/-2 cr of each other. Other samples whose nature generally preclude sample splitting are marked"**" in the Split Analysis column.
