SUMMARY

1.1 Radiological Environmental Monitoring Program The Annual Radiological Environmental Operating Report (AREOR) presents data obtained through analyses of environmental samples collected for Palisades Radiological Environmental Monitoring Program (REMP). The reporting period for this report is from January 1 through December 31, 2019. This report fulfills the requirements of Palisades Technical Specification 5.6.2.

No measurable levels of radiation above baseline levels attributable to Palisades operation were detected in the environment. The 2019 REMP thus substantiated the adequacy of source control and effluent-monitoring at Palisades with no detectable

impact of plant operations on the environment.

Palisades established the REMP prior to the station becoming operational to provide data on background radiation and radioactivity normally present in the area.

Palisades has continued to monitor the environment by sampling air, water, sediment, broad leaf vegetation, fish, and food products, as well as measuring direct radiation.

Palisades also samples milk if milk-producing animals used for human consumption are present within five miles (8 km) of the plant. The requirements of the REMP are formally described in the offsite dose calculation manual (ODCM), a site specific regulatory document.

The REMP includes sampling indicator and control locations. The REMP utilizes indicator locations near Palisades to identify buildup of radioactivity and control locations to provide a comparison for indicator locations. Indicator, control, and pre-operational results are used to assess any impact Palisades operation might have had on the surro1:Jnding environment. _

All 2019 REMP results support the conclusion that the surrounding environment is minimally affected by Palisades' effluents. No activity in any REMP sample from 2019 was attributed to Palisades' effluents.

1.2 Reporting Levels No samples equaled or exceeded reporting levels.

1.3 Sample Deviations During 2019, environmental sampling was performed for eight media types (airborne, surface water, drinking water, offsite groundwater, sediment, broad leaf vegetation, fish, and food products) and for direct radiation. All REMP samples were obtained as required by the ODCM in 2019 with the exception of six instances of sample deviations which are further discussed in Attachment 1 Table 8.

Plant: Palisades I Year: 2019 I Page 4 of 57 Annual Radiological Environmental Operating Report 1.4 Program Modifications

1. There was one program modification as a result of the 2019 land use census.

This modification was for a new, identified critical goat location and will be used in offsite dose modeling calculations. Goat milk sampling will be performed in accordance with Palisades ODCM assuming the goat milk is available to be sampled. Broad leaf vegetation samples will continue to be collected in accordance with Palisades ODCM. There is no expected impact to trending of REMP data due to this change.

2.0 INTRODUCTION

2.1 Radiological Environmental Monitoring Program Palisades established the REMP as defined in the ODCM to fulfill 10 CFR Part 50 Appendix I Section IV.8.2. The REMP supplements the radiological effluent monitoring program by verifying that the concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.

2.2 Pathways Monitored The airborne, direct radiation, waterborne, and ingestion pathways are monitored as required by Table 1 through Table 4.

Section 4.0 of this report provides a discussion of 2019 sampling results and Section 5.0 provides a summary of results for the monitored exposure pathways.

2.3* Land Use Census Palisades conducts a land use census annually to identify changes in uses of land within five miles of the site that would require modifications to the REMP and the ODCM. The purpose of this census is to identify critical receptor pathways for the purpose of effluent modeling and REMP sampling.

The locations in Figure 3 correspond to the TLD and Air Sampler locations in Table 1 and Table 2.

4.0 INTERPRETATION AND TRENDS OF RESULTS 4.1 Air Particulate and Radioiodine Sample Results There were 312 air samples collected and analyzed for gross beta and 1-131 during 2019. Air iodine and particulate samples are collected weekly from six air-sampling locations. Air is metered into the sampling unit through a 47-mm air filter (for particulate) and an air iodine cartridge. The filters are in series with one another and housed within the same filter holder. An "as found" and "as left" leak test is performed at each station during each sample collection. Weekly samples were sent to Teledyne Brown Engineering Environmental Services for analysis.

Plant: Palisades I Year: 2019 I Page 13 of 57 Annual Radiological Environmental Operating Report Analysis of the airborne particulate sample data, between the five near-site indicator locations and the control location, indicate no difference between indicator and control locations. The average concentration of gross beta activity among all indicator locations was 2.16E-02 pCi/m 3 and was 2.07E-02 pCi/m 3 for the control location. All I-131 activity results, for both indicator and control locations, were below the minimum detectable activity (MDA). Gamma isotopic analysis is performed quarterly on a quarterly composite of the filter papers. All radionuclides detected (Be-7) were naturally occurring radionuclides which are not attributed to plant effluents.

Palisades' pre-operational environmental study showed naturally occurring gross beta radiation between 0.03 and 3.0 pCi/m 3 with a similar trend between stations onsite, in the surrounding community, and control stations. The activity results from 2019 indicate there is no measureable change between pre-operational airborne gross beta activity and present day airborne gross beta activity.

There was one REMP deviation in 2019 involving air sampling. This instance is discussed in Attachment 1 Table 8.

In the absence of plant-related gamma radionuclides, gross beta activity is attributed to naturally occurring radionuclides. The air sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2019. This

~onclusion is that the surrounding environment is minimally affected :by Palisades' effluents. No REMP air samples from 2019 contained measurable radiological materials attributed to Palisades' effluents.

Plant: Palisades I Year: 2019 I Page 14 of 57 Annual Radiological Environmental Operating Report 4.2 Thermoluminescent Dosimetry CTLD) Sample Results Palisades reports measured dose as net exposure (subtracting transit reading) normalized to 92 days. TLDs are oriented in an inner ring, outer ring, and control locations. The inner ring consists of 11 TLDs, the outer ring consists of 9 TLDs, and there are 3 control locations. This orientation allows for monitoring all 9 overland compass sectors surrounding Palisades. To assess the effect of direct and shine radiation from Palisades to the environment the inner ring, outer ring, and control TLDs are compared to one another. Additionally, each individual TLD location is compared to a baseline of data which was created from a comprehensive review of data from 2011 through 2016. The high and low values for the baseline are based upon two standard deviations for each data point from 2011 through 2016,. If a value is measured outside the baseline additional follow-up investigation is performed to evaluate the cause. During 2019 all TLDs trended normal and no TLDs were outside the baseline. This evaluation identified no noticeable trend that would indicate that the ambient radiation levels are being affected by plant operations. During 2019 there was one instance of a REMP deviations involving one TLD. This instance is discussed in Attachment 1 Table 8. Table 5 shows the consistent trend of average inner ring, outer ring, and control TLDs.

TLD measurements taken as part of Palisades' pre-operational environmental study used ~ifferent instrumentation which had difficulty ir:, achieving desired sensitivity and accuracy. A more sensitive type of TLD was implemented in 1971 and the present day TLD device used is the industry standard. TLD data has trended consistently throughout the several most recent independent spent fuel storage installation (ISFSI) loading campaigns which indicates these loading campaigns have had no measurable effect on the environment.

Activity from TLD measurements in the environment is attributed to naturally occurring background radiation and not from Palisades' direct or shine radiation.

Plant: Palisades I Year: 2019 I Page 15 of 57 Annual Radiological Environmental Operating Report 4.3 Waterborne Sample Results During 2019 Palisades implemented the REMP in accordance with the ODCM for collection of surface, drinking, and groundwater. For all surface, drinking, and groundwater indicator samples, the same control sample is used as a baseline for comparison. That control sample is referred to as the "Ludington Control" and is collected 201 km north of Palisades. The Ludington Control sample is analyzed monthly and is a composite of daily samples. The Ludington Control sample is analyzed for gamma radionuclide, tritium, and gross beta activity. In 2019 the only radionuclide activity detected in Ludington Control water was naturally occurring isotopes (K-40). Of the twelve Ludington Control samples collected in 2019, four contained detectable gross beta with an average va.lue of 2.81 pCi/L. The. gross beta activity is a result of naturally occurring radionuclide and is not attributed to Palisades' effluents.

4.3.1 Surface Water The indicator surface water samples collected and analyzed for the REMP include "Lake In" water. This sample is Lake Michigan water after it has traveled through the Palisades' intake structure and traveling screens. This sample is collected daily and composited into a monthly sample which is analyzed .for gamma radionuclide and tritium onsite. This sample is also analyzed by Teledyne Brown Engineering Environmental Services for gamma, tritium, and gross beta activity. All radionuclide detected (K-40, Ra-226, and Th-228) were naturally occurring and are not attributed to Palisades' effluents. Three out of the twelve monthly samples contained measurable gross beta with the average detectable gross beta activity at 2.88 pCi/L.

Palisades' pre-operational environmental study established a baseline of gross beta activity for the site before Palisades was operational. The study results for surface water showed consistently measurable results for gross beta activity between 11 - 18

(+/- 5) pCi/L.

The surface water sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2019. This conclusion is that the surrounding environment is minimally affected by Palisades' effluents. No REMP surface water samples from 2019 contained measurable radiological materials

.attributed to Palisades' effluents.

i i 4.3.2 Drinking Water The indicator drinking water samples collected and analyzed for the REMP include "Domestic Water, "South Haven Drinking Water", and "Palisades Park Community Water". All samples are analyzed for gamma, tritium, and gross beta by Teledyne Brown Engineering Environmental Services.

Plant: Palisades I Year: 2019 I Page 16 of 57 Annual Radioloaical Environmental Operating Report Domestic Water is collected onsite from a potable water system, typically an eyewash station. This sample is collected daily and composited into a monthly sample which is analyzed for gamma radionuclide and tritium onsite. All radionuclide detected (K-40, Ra-226, and Th-228) were naturally occurring and are not attributed to Palisades' effluents. Four out of the twelve monthly samples contained measurable gross beta activity with the average detectable gross beta activity at 2.56 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide. Domestic water is not required by the ODCM for the REMP. This sample is collected as part of the NRC bulletin 80-10 commitments and is included in this report because the data strengthens the REMP.

South Haven Drinking Wat~r is collected from the.. City of South Haven Water Treatment facility located in South Haven. All radionuclide detected (K-40 and Th-228) were naturally occurring and are not attributed to Palisades' effluents. Four out of the twelve monthly samples contained measurable gross beta with the average detectable gross beta activity at 2. 78 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide.

Palisades Park Community Water is collected once per month as a grab sample from a community just south of Palisades while the facility is operational (summer months).

This sample is analyzed for gamma, tritium, and gross beta activity. No radionuclides were detected via gamma !Spectroscopy and no tr_ itium was detected in any samples.

Three out of the six monthly samples contained measurable gross beta activity with the average detectable gross beta activity at 3.27 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide. Gross beta activity is not required by the ODCM for this sample but is performed for trending purposes and to strengthen the REMP.

Palisades' pre-operational environmental study established a baseline of gross beta activity for the site before Palisades was operational. The study results relied upon as a baseline for drinking water analysis are the same results as with surface water, that being consistent gross beta activity between 11 - 18 (+/- 5) pCi/L.

The drinking water sample results collected, in accordance with the REMP, support the conclusions of the effluents monitoring program for 2019. This conclusion is that the surrounding environment is minimally affected by Palisades' effluents. No REMP drinking water samples from 2019 contained measurable radiological materials attributed to Palisades' effluents. ; ;

Plant: Palisades I Year: 2019 I Page 17 of 57 Annual Radiological Environmental Operating Report 4.3.3 Groundwater Palisades implements an extensive groundwater monitoring program in accordance with NEl-0707, "Industry Ground Water Protection Initiative - Final Guidance Document". This program is designed to identify onsite leaks to groundwater to allow for prompt repair or isolation of the leak. The results of the onsite groundwater program are described in the Annual Radioactive Effluent Release Report (ARERR).

Palisades samples one offsite groundwater location. This sample is not required by Palisades ODCM but is procedurally implemented to strengthen the program overall.

The REMP groundwater sample is the "Palisades Park Commercial Well Water" sample. This sample is collected once per month as a grab sample from a community just south of Palisades.,while the facility is operational (summer months).

This sample is analyzed for gamma, tritium, and gross beta activity by Teledyne Brown Engineering Environmental Services. No radionuclides were detected via gamma spectroscopy and no tritium was detected in any samples. Four out of the six monthly samples contained measurable gross beta with the average detectable gross beta activity at 4.41 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide.

Palisades' pre-operational environmental study established a baseline of gross beta activity for the site before Palisades was operational. The study results were that five well water samples from Palisades contained gross beta activity above 5 pCi/L with the highest value being 16 pCi/L. Two samples from Covert Park well water contained gross beta activity at 6 and 7 pCi/L.

The groundwater sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2019. This conclusion is that the surrounding environment is minimally affected by Palisades' effluents. No REMP groundwater samples from 2019 contained measurable radiological materials attributed to Palisades' effluents.

Plant: Palisades I Year: 2019 I Page 18 of 57 Annual Radiological Environmental Operating Report 4.4 Soil Sample Results Sediment samples are collected two times per year north and south of the plant from the beach on Lake Michigan. One sample is collected at the southern edge of the property and a second sample is collected approximately 0.5 miles north of the plant.

The sample south of the plant is not required by the ODCM but is collected and analyzed to strengthen the REMP. Both the north and south sediment samples are analyzed for gamma radionuclide. In 2019, the only radionuclides detected were naturally occurring (Ac-228, K-40, Th-228, Th-232, and Ra-226) isotopes which are not attributed to Palisades' effluents. In accordance with the ODCM, no control sample is collected for this sample type.

'I *~ ,;.

Soil samples were not specifically part of the Palisades' pre-operational environmental study however a study of Cs-137 found in soil (due to global events such as historical atomic testing and fallout) was performed by Palisades in 2011.

Analysis was performed of soil in the surrounding area (Southwest Michigan) which showed Cs-137 concentrations between 1.41 E-08 uCi/g and 5.68E-07 uCi/g with an average of 2.68E-07 uCi/g. Considering similar studies performed by other utilities, a conservative (low) background of 1.BE-07 uCi/g Cs-137 in soil is assumed to be due to global fallout.

The sediment sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2019: This conclusion is that the surrounding environment is minimally affected by Palisades' effluents. No REMP sediment samples from 2019 contained measurable radiological materials attributed to Palisades' effluents.

4.5 Ingestion Sample Results 4.5.1 Milk Sample Results Indicator milk samples were not available to be collected during 2019. The control milk samples were collected for three months to establish a baseline of data if the indicator samples were to become available. All radionuclide detected in these samples (K-40) were naturally occurring and are not attributed to Palisades' effluents.

4.5.2 Broad leaf Sample Results In accordance with Palisades ODCM three different kinds of broad leaf vegetation is sampled from two onsite (indicator) locations and one offsite (control) location due to the fact that milk sampling is not performed. Broad leaf samples are collected once per month during the growing season and analyzed for gamma radionuclides including iodine-131. Naturally occurring radionuclide detected in broad leaf vegetation (Be-7, K-40, and Th-228) are not attributed to Palisades' effluents. Cs-137 detected in broad leaf vegetation was attributed to historical global atomic testing and biological uptake. Cs-137 was detected at location BV1 (0.4 miles SSE) for two out of the five monthly samples. The average concentration of Cs-137 was 87.9 pCi/kg.

It is not abnormal to detect Cs-137 in broad leaf samples. Palisades procedurally implements a conservative administrative action value to perform additional reviews if the activity of broad leaf samples exceeds 146 pCi/kg Cs-137. The absence of Cs-134 and the absence of other radionuclides measured in the plant effluent and coolant systems further support that the Cs-137 detected in broadleaf is not a result of Palisades activity.

Plant: Palisades I Year: 2019 I Page 19 of 57 Annual Radiological Environmental Operating Report The pre-operational environmental study consisted in part of Cs-137 and Sr-90 analysis for crops and milk. These (and broadleaf) sample results are a result of historical global atomic testing and biological uptake. The pre-operational study identified Cs-137 in milk samples ranging from 2 to 70 pCi/L and Sr-90 ranging from 5 to 15 pCi/L. For crop samples, gross gamma activity was generally between 0.11 and 0.22 pCi/g and gross beta activity was generally between 0.72 to 3.31 pCi/g.

The broad leaf sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2019. This conclusion is that the surrounding environment is minimally affected by Palisades' effluents. No REMP broadleaf samples from 2019 contained measurable radiological materials attributed to Palisade.s' effluents.

4.5.3 Fish Sample Results Indicator and Control fish samples are collected and analyzed twice per year. The filet of the fish is analyzed for gamma radionuclide. The indicator fish are collected near Palisades lake-out discharge point. At least 2 species of commercial or recreational importance are collected and analyzed. At least one sample of the same species is collected as a control sample. The control fish are collected 201 km north of Palisades near Ludington, Ml. In 2019, the only radionuclides detected among .all fish samples were naturally occurring radionuclides (K-40 and Th-228) which were not attributed to Palisades' effluents. . .

Palisades' pre-operational environmental study established a baseline for radiological material in fish. The study established that gross beta activity is generally between 2 and 4 pCi/g and gross gamma activity is generally between 0.04 and 0.4 pCi/g in fish.

Cs-137 and Sr-90 were measured in the pre-operational study and were expected to be measured due to known worldwide contamination from historical global atomic testing. Cs-137 detected was generally between 0.10 and 0.25 pCi/g and Sr-90 detected was generally between 0.01 to 0.04 pCi/g in the pre-operational environmental study.

The fish sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2019. This conclusion is that the surrounding environment is minimally affected by Palisades' effluents.

4.5.4 Food Product Sample Results Two principal fruit crops are collected once per year and analyzed for gamma radionuclides including lodine-131 in accordance with the REMP. The two crops sampled in 2019 were blueberries and apples. The results of all sample analysis show that only naturally occurring radionuclides (K-40 and Be-7) were present. In accordance with the ODCM, no control sample is collected for this sample type.

Palisades' pre-operational environmental study performed radiological analysis on a variety of crop samples. Gross gamma activity was generally between 0.11 and 0.22 pCi/g and gross beta activity was generally between 0.72 to 3.31 pCi/g.

Plant: Palisades I Year: 2019 I Page 20 of 57 Annual Radiological Environmental Operating Report The fruit sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2019. This conclusion is that the surrounding environment is minimally affected by Palisades' effluents. No REMP fruit samples from 2019 contained measurable radiological materials attributed to Palisades' effluents.

4.6 Land Use Census Results The 2019 land use census results are tabulated in Table 6. The results of the census yielded a new critical receptor (goat in ESE sector) for dose modeling purposes.

Goat milk sampling will be performed as available (seasonally) in 2020.

Plant: Palisades I Year: 2019 I Page 54 of 57 Annual Radiological Environmental Operating Report Attachment 3 Page 1 of 3 lnterlaboratory Comparison Program Results 1.0 Summary Summary of Results - Inter-laboratory Comparison Program (ICP)

The Teledyne Brown Engineering (TBE) Laboratory analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation, and water matrices for various analytes. The PE samples supplied by Analytics Inc.,

Environmental Re~ource Associates (E~A) and Department .of Energy (DOE)

Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria:

A. Analytics Evaluation Criteria Analytics evaluation report provides a ratio of TBE's result and Analytics known value. Since flag values are not assigned by Analytics, TBE evaluates the reported ratios based on internal Quality control (QC) requirements based on the DOE MAPEP criteria.

B. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the United States Environmental Protection Agency (USEPA), National Environmental Laboratory Accreditation Conference (NELAC), state-specific Performance Testing (PT) program requirements .

or ERA's Standard Operating Procedure (SOP) for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.

C. DOE Evaluation Criteria MAPEP's e,valuation report provjdes an acceptance rj:lnge with associate~

flag values. MAPEP defines three levels of performance:

Acceptable (flag = "A") - result within +/- 20% of the reference value

Acceptable with Warning (flag = "W') - result falls in the +/- 20% to +/- 30% of the reference value

Not Acceptable (flag = "N") - bias is greater than 30% of the reference value Note: The Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which do not resemble typical environmental samples obtained at commercial nuclear power facilities.

Plant: Palisades I Year: 2019 I Page 55 of 57 Annual Radiological Environmental Operating Report Attachment 3 Page 2 of 3 lnterlaboratory Comparison Program Results A non-conformance report (NCR) is generated for conditions adverse or potentially adverse to quality.

lnterlaboratory Cross-Check Program (1) Analytics Environmental Cross Check Program Thirteen nuclides in milk, air particulate, air iodine (charcoal), soil, and water samples were evaluated. All of the environmental analyses performed were evaluated as within the acceptable/acceptable with warning range except for one Cr-51 in soil sample. NCR 19-27 was initiated to address the failure and Corrective Actions were issued. All raw data and associated QC data were reviewed and fell within acceptance limits. No client data was affected by the failure.

(2) DOE's MAPEP Quality Assessment Program Sixteen nuclides in water, air particulate, soil, and vegetation samples were evaluated. All of the environmental analyses performed were evaluated as within the acceptable/acceptable with warning criteria except for the following: one Sr-90 in soil sample, one Sr-90 in vegetation sample (statistical failure for false positive), Ni-63 in soil sample, and two Am-241 in water samples. NCRs 19-12, 19-13, 19-14, 19-25 and 19-26 were initiated to address the failures and Corrective Actions were issued. All raw data and associated QC data-were reviewed and fell within acceptance limits. No client data was affected by the failures.

(3) ERA Environmental Cross Check Program Twelve nuclides were evaluated in water samples. All analyses performed were within the acceptable criteria except for the following: Cs-134, Sr-89, Sr-90 and Gross Alpha in water samples (one each). NCRs 19-'.10, 19-11, 19.:23 and .19-24 were initiated to address the failures and Corrective Actions were issued. All raw data and associated QC data were reviewed and fell within acceptance limits. No client data was affected by the failures.

lntralaboratory Cross-Check Program During this reporting period, 37 nuclides in various matrices, including air particulate, charcoal, vegetation, fish, milk, soil/solid, and water were analyzed by means of the laboratory's internal process control program. The TBE-ES laboratory's internal process control program evaluated 6755 analyses during this period.

(1) Blanks - During this reporting period, 1587/1588 environmental blanks analyzed were less than the MDC. One QC blank was positive, but the sample results were greater than 10 times the level of activity in the blank. A case narrative was included with the sample results.

Plant: Palisades I Year: 2019 I Page 56 of 57 Annual Radiological Environmental Operating Report Attachment 3 Page 3 of 3 lnterlaboratory Comparison Program Results (2) Spikes .:. During this reporting period, all 1573 environmental spikes and matrix spikes analyzed were within the acceptance criteria.

(3) Duplicates - All of the 3594 duplicate sets analyzed were within acceptance criteria.

The interlaboratory and intra laboratory comparison program provides evidence of "in control" counting systems and methods,. and that the laboratqries are producing a9curate and reliable .,

data.

Thermoluminescent dosimeters (TLDs) are analyzed by an offsite vendor, "Environmental Dosimetry Company" (EDC). The TLDs used are Panasonic 814 Environmental dosimeters.

EDC implements an internal quality assurance program and audits the program annually.

Some of EDC's vendors also perform independent testing on the TLDs accuracy and precision. During 2019 100% (72/72) of the individual dosimeters met the criterion for accuracy (plus or minus 15%) and 100% (72/72) met the criterion for precision (plus or minus 12.8%). Also, 100% (12/12) of the dosimeter sets evaiuated met EDC acceptance criteria for .

mean bias *and precision and 100% (6/6) of independent testing passed the performance criteria. One internal assessment was performed in 2019.There were no findings identified.

Plant: Palisades I Year: 2019 I Page 57 of 57 Annual Radiological Environmental Operating Report Attachment 4 Previous AREOR ERRATA There were five errors identified in the 2018 AREOR . All five errors were considered "small errors" in accordance with the guidance given in Regulatory Guide 1.21 Revision 2 (a guidance document published by the NRC for annual effluent reporting). More specifically the errors do not impede the NRC's ability to adequately assess the information and the errors do not alter the intent of the report.

Following this page there are five corrected pages from the 2018 AREOR showing the errors and the corrected information.

(1) In Table 7 the fraction of detectable results for the indicator and control column was listed as "(O I 30)" for all analyses. The fraction of detectable results for the indicator and control column should have been "(O / 6)" for all analyses.

(2) Page 21 of 54 through 31 of 54 should have listed "Palisades" and "2018" in the header instead of "Enter Plant Name" and "YEAR". Page 22 of 54 was included in the ERRATA section of this report to show this error. Other pages affected are not included in the ERRATA section of this report.

(3) In Table 15 the required LLD for Zr-95 was listed as "30" and should have been listed as "15" (4) In Table 21 the collection data for blueberries and apples was incorrect. The date "06/28/2016" should have been "07/09/2018" and the date "06/28/2016" should have been "09/24/2018".

(5) In Table 24 there were two columns for K-40 results. The left most K-40 column should have been deleted.
