ABSTRACT The Radiological Environmental Monitoring Program (REMP) is an ongoing program conducted by Arizona Public Service Company (APS) for the Palo Verde Nuclear Generating Station (PVNGS).

Various types of environmental samples are collected near PVNGS and analyzed for plant related radionuclide concentrations.

During 2013, the following categories of samples were collected by APS:

Broad leaf vegetation

" Ground water Drinking water Surface water

Airborne particulate and radioiodine Goat milk

Sludge and sediment Thermoluminescent dosimeters (TLDs) were used to measure environmental gamma radiation. The Environmental TLD program is also conducted by APS.

The Arizona Radiation Regulatory Agency (ARRA) performs radiochemistry analyses on various duplicate samples provided to them by APS. Samples analyzed by ARRA include onsite samples from the Reservoirs, Evaporation Ponds, and two (2) deep wells. Offsite samples analyzed by ARRA include two (2) local resident wells. ARRA also performs air sampling at seven (7) offsite locations identical to APS and maintains approximately fifty (50) environmental TLD monitoring locations, eighteen (18) of which are duplicates of APS locations.

A comparison of pre-operational and operational data indicates no changes to environmental radiation levels.

(NOTE: Reference to APS throughout this report refers to PVNGS personnel)

PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2013 1

OPERATIONAL RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM

1.

Introduction This report presents the results of the operational radiological environmental monitoring program conducted by Arizona Public Service Company (APS). The Radiological Environmental Monitoring Program (REMP) was established for the Palo Verde Nuclear Generating Station (PVNGS) by APS in 1979.

This report contains the measurements and findings for 2013. All references are specifically identified in Section 12.

The Radiological Environmental Monitoring Program provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of members of the public resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 and thereby supplements the radiological effluent monitoring program by verifying that the measurable 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. Guidance for this monitoring program is provided by the US Nuclear Regulatory Commission (USNRC) in their Radiological Assessment Branch Technical Position on Environmental Monitoring, Revision 1, November 1979 (incorporated into NUREG 1301).

Results from the REMP help to evaluate sources of elevated levels of radioactivity in the environment (e.g., atmospheric nuclear detonations or abnormal plant releases).

The Land Use Census ensures that changes in the use of areas at and beyond the site boundary are identified and that modifications to the REMP are made if required by the results of this census.

This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50.

The Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive material in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10 CFR Part 50.

Results of the PVNGS pre-operational environmental monitoring program are presented in Reference 1.

The initial criticality of Unit 1 occurred May 25, 1985. Initial criticality for Units 2 and 3 were April 18, 1986, and October 25, 1987, respectively. PVNGS operational findings (historical) are presented in Reference 2.

PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2013 2

2.

Description of the Monitoring Program APS and vendor organizations performed the pre-operational radiological environmental monitoring program between 1979 and 1985. APS and vendors continued the program into the operational phase.

2.1.

Radiological Environmental Monitoring Program The assessment program consists of routine measurements of environmental gamma radiation and of radionuclide concentrations in media such as air, groundwater, drinking water, surface water, vegetation, milk, sludge, and sediment.

Samples were collected by APS at the monitoring sites shown in Figures 2.1 and 2.2. The specific sample types, sampling locations, and sampling frequencies, as set forth in the PVNGS Offsite Dose Calculation Manual (ODCM), Reference 4, are presented in Tables 2.1, 2.2 and 9.1. Additional onsite sampling (outside the scope of the ODCM) is performed to supplement the REMP. All results are included in this report. Routine sample analyses were performed at the onsite Central Chemistry Laboratory and Operating Unit laboratories. Analyses for hard-to-detect radionuclides were performed by GEL Laboratories LLC.

Environmental gamma radiation measurements were performed by APS using TLDs at fifty (50) locations near PVNGS. The PVNGS Dosimetry Department is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) to perform ionizing radiation dosimeter analyses.

In addition to monitoring environmental media, a land use census is performed annually to identify the nearest milk animals, residents, and gardens. This information is used to evaluate the potential dose to members of the public for those exposure pathways that are indicated.

2.2.

Radiological Environmental Monitoring Program Changes for 2013 There were no changes to the Radiological Environmental Monitoring Program that impacted the Off-site Dose Calculation Manual (ODCM) Revision 26.

PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2013 3

It 2.3.

REMP Deviations/Abnormal Events Summary During calendar year 2013, there were seven (7) deviations/abnormal events with regard to the monitoring program. Refer to Table 2.3 for more detail and any corrective actions taken.

The first six (1-6) deviations were exceedances of the quarterly 1-131 reporting level of 20 pCi/L. This occurred at the following locations: 45 acre reservoir first and second calendar quarters, 85 acre reservoir second quarter, Evaporation Pond lB first and third quarters, Evaporation Pond 2B second quarter. The source is radiopharmaceutical 1-131 that originates in the Phoenix sewage effluent that supplies makeup to the Reservoirs and Circulating Water system. This water is wasted to the Evaporation Ponds. This is not a plant effluent.

The seventh (7) deviation was a mass air flowmeter found to be out of tolerance. This mass air flowmeter was used to calibrate air sample stations. The flowmeter failed in the conservative direction and there was no adverse impact to sample data.

The eighth (8) and final deviation for 2013 was an air sample pump failure at site #4.

This resulted in not being able to collect a sample for that location.

This is a supplemental site, not required per the ODCM.

In July of 2013, the REMP air samplers were moved to a lower height. This is recorded with Letter 218-03709-JLM. These sample stations were lowered for industrial safety concerns.

2.4.

Ground Water Protection PVNGS has implemented a groundwater protection initiative developed by the Nuclear Energy Institute (NEI). The implementation of this initiative, NEI 07-07 (Industry Ground Water Protection Initiative - Final Guidance Document, August 2007), provides added assurance that groundwater will not be adversely affected by PVNGS operations.

Several monitoring wells have been installed to monitor the subsurface water and shallow aquifer at Units 1, 2, and 3. These wells are sampled monthly and quarterly for chemical and radiological parameters. The State of Arizona Aquifer Protection Permit (Area-Wide)

No. P-100388 (APP) provides agreed upon monitoring parameters and reporting thresholds. Sample results for the shallow aquifer wells are reported in the PVNGS Annual Radioactive Effluent Release Report (ARERR). The State of Arizona APP provides specific regulatory criteria for ground water protection.

Three subsurface samples were obtained, one each from Units 2 and 3 tritium monitoring wells, and one from the shallow aquifer outside of the Unit I radiological controlled area (RCA). These samples were analyzed for hard-to-detect radionuclides (e.g. C-14, Fe-55, Ni-63, Sr-90) as a verification that there are no underground leaks from plant systems that may affect groundwater. All results were <MDA. Refer to Table 8.12 for sample results.

2. The 45 acre Reservoir the second quarter 1-131 level of 20 pCi/liter.

3. The 85 acre Reservoir the second quarter 1-131 level of 20 pCi/liter.

4. Evaporation Pond IB the first quarter 1-131 level of 20 pCi/liter.

6. Evaporation Pond 2B the second quarter 1-131 level of 20 pCi/liter exceeded reporting exceeded reporting exceeded reporting exceeded reporting exceeded reporting exceeded reporting Actions taken 1-6. Initial sample results exceeding 20 pCi/liter are validated when seen in surface water. The verification analysis results also showed levels > 20 pCi/liter. The elevated 1-131 concentration is due to radiopharmaceutical 1-131 that is present in the reclaimed sewage water that supplies Circulating Water and is not the result of plant effluents.

The source is radiopharmaceutical 1-131 that originates in the Phoenix sewage effluent that supplies makeup to the Reservoirs and Circulating Water system. This water is wasted to the Evaporation Ponds via Circulating Water blowdown.

Because the 1-131 is not the result of plant effluents, no Special Report is required. This information is provided in this report as required by the ODCM. Refer to Corrective Action Program documents CRDR 4405324, CRDR 4343153, and 4442148 for the evaluation of exceeding the ODCM Reporting Level. No additional actions are necessary.

7. The air flowmeter used for calibration of air sampling stations was found to be out of tolerance, having failed in the conservative direction. CRDR 4442150 provides evaluations for impact to REMP data. No impacts were identified. No additional actions are necessary.

8. The air sample pump failed during the sample period, resulting in the inability to determine the actual sample volume. The pump was replaced and the sample for the next week was valid. No further actions required. The last pump failure occurred in 2009.

7. Mass air flowmeter EG7057 was found to be out of tolerance during normal calibrations.

8. Air sample site #4 sample pump failed between 12/10/2013 and 12/17/2013.

Sample Collection Program APS personnel using PVNGS procedures collected all samples.

3.1.

Water Weekly samples were collected from four (4) residence wells for monthly and quarterly composites. Samples were collected in one-gallon containers and 500 mL glass bottles. The samples were analyzed for gross beta, gamma emitting radionuclides and tritium.

Quarterly grab samples were collected from the 45 and 85 acre Reservoirs, Evaporation Ponds lA/B/C, 2A/B, and 3A/B, and onsite wells 34abb and 27ddc. Samples were collected in one-gallon containers and 500 mL glass bottles. Samples were analyzed for gamma emitting radionuclides and tritium.

Treated sewage effluent from the City of Phoenix was sampled as a weekly composite at the onsite Water Reclamation Facility (WRF), and analyzed for gamma emitting radionuclides. A monthly composite was analyzed for tritium.

3.2.

Vegetation Vegetation samples were collected monthly, as available, and were analyzed for gamma emitting radionuclides.

3.3.

Milk Goat milk samples were collected monthly, as available, and were analyzed for gamma emitting radionuclides, including low level 1-131.

3.4.

Air Air particulate filters and charcoal cartridges were collected at ten (10) sites on a weekly basis.

Particulate filters were analyzed for gross beta. Charcoal cartridges were analyzed for 1-131.

Particulate filters were composited quarterly, by location, and analyzed for gamma emitting radionuclides.

3.5.

Sludge and Sediment Sludge samples were obtained weekly from the WRF waste centrifuge (whenever the plant was operational) and analyzed for gamma emitting radionuclides. Cooling tower sludge was analyzed for gamma emitting radionuclides prior to disposal in the WRF sludge landfill.

Isotopic Detection Limits and Reporting Criteria 6.1.

Lower Limits of Detection The lower limits of detection (LLD) and the method for calculation are specified in the PVNGS ODCM, Reference 4. The ODCM required a priori LLDs are presented in Table 6.1. For reference, a priori LLDs are indicated at the top of data tables for samples having required LLD values.

6.2.

Data Reporting Criteria All results that are greater than the Minimum Detectable Activity (MDA) (a posteriori LLD) are reported as positive activity with its associated 2a counting error. All results that are less than the MDA are reported as less than values at the associated MDA. For example, if the MDA is 12 pCi/liter, the value is reported as <12.

Typical MDA values are presented in Table 6.3.

Occasionally, the PVNGS ODCM a priori LLDs may not be achieved as a result of:

Background fluctuations Unavoidably small sample sizes The presence of interfering radionuclides Self absorption corrections Decay corrections for short half-life radionuclides Other uncontrollable circumstances In these instances, the contributing factors will be noted in the table where the data are presented.

A summary of deviations/abnormal events is presented in Table 2.3 and includes a description of any sample results that did not meet a priori LLD requirements.

6.3.

LLD and Reporting Criteria Overview Making a reasonable estimate of the limits of detection for a counting procedure or a radiochemical method is usually complicated by the presence of significant background. It must be considered that the background or blank is not a fixed value but that a series of replicates would be normally distributed. The desired net activity is the difference between the gross and background activity distributions. The interpretation of this difference becomes a problem if the two distributions intersect as indicated in the diagram.

BACKGROUND GROSS If a sufficient number of replicate analyses are run, it is expected that the results would fall in a normal Gaussian distribution. Standard statistics allow an estimate of the probability of any particular deviation from the mean value. It is common practice to report the mean +/- one or two standard deviations as the result. In routine analysis, such replication is not carried out, and it is not possible to report a Gaussian standard deviation. With counting procedures, however, it is possible to estimate a Poisson standard deviation directly from the count. Data are commonly reported as the measured value +/- one or two Poisson standard deviations. The reported values are then considered to give some indication of the range in which the true value might be expected to occur.

A LLD is the smallest amount of sample activity that will yield a net count for which there is confidence at a predetermined level that activity is present. LLDs are calculated values for individual radionuclides based on a number of different factors including sample size, counting efficiency and background count rate of the instrument, the background and sample counting time, the decay time, and the chemical recovery of the analytical procedures. A minimum detectable activity value (MDA) is the smallest amount of activity that can be detected in an actual sample and uses the values obtained from the instrument and outcome of the analytical process. Therefore, the MDA values may differ from the calculated LLD values if the sample size and chemical recovery, decay values, or the instrument efficiency, background, or count time differed from those used in the LLD calculation.

PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2013 15

The factors governing the calculation of the LLD and MDA values are discussed below:

1. Sample Size

2. Counting Efficiency The fundamental quantity in the measurement of a radioactive substance is the number of disintegrations per unit time. As with most physical measurements in analytical chemistry, an absolute measurement of the disintegration rate is seldom possible, rather it is necessary to compare the sample with one or more standards. The standards determine the counter efficiency that may then be used to convert sample counts per minute (cpm) to disintegrations per minute (dpm).

3. Background Count Rate Any counter will show a certain counting rate without a sample in position. This background counting rate comes from several sources: 1) natural environmental radiation from the surrounding materials, 2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. The background counting rate will depend on the amounts of these types of radiation and the sensitivity of the counter to the radiation.

4. Background and Sample Counting Time The amount of time devoted to the counting of the background depends on the level of activity being measured. In general, with low level samples, this time should be about equal to that devoted to counting a sample.

5. Time Interval between Sample Collection and Counting Decay measurements are useful in identifying certain short-lived nuclides. The disintegration constant is one of the basic characteristics of a specific radionuclide and is readily determined, if the half-life is sufficiently short. To ensure the required LLDs are achieved, appropriate decay correction values are used to account for radioactive decay during transit time and sample processing.

Data Interpretations and Conclusions Associated with the analytical process are potential random and systematic errors. Systematic errors can be caused by instrument malfunctions, incomplete precipitation, back scattering, and self-absorption. Random errors are beyond the control of the analyst.

Efforts are made to minimize both systematic and random errors in the data reported. Systematic errors are minimized by performing reviews throughout the analysis. For example, instruments are checked routinely with radioactive sources, and recovery and self-absorption factors based on individual sample analyses are incorporated into the calculation equations where necessary. Random errors are reduced by comparing all data to historical data for the same site and performing comparisons between analytical results when available. In addition, when data do not appear to match historical results, analyses may be rerun on a separate aliquot of the sample to verify the presence of the activity. The acceptance of data is dependent upon the results of quality control samples and is part of the data review process for all analytical results.

The "plus or minus value" reported with each analytical result represents the counting error associated with the result and gives the 95% confidence (2a) interval around the data.

Most samples contain radioactivity associated with natural background/cosmic radioactivity (e.g. K-40, Th-234, and Be-7). Gross beta results for drinking water and air are due to natural background. Gamma emitting radionuclides, which can be attributed to natural background sources, are not indicated in this reort.

Results and interpretation of the data for all of the samples analyzed during 2013 are presented in the following sections.

8.1.

Air Particulates Weekly gross beta results, in quarterly format, are presented in Tables 8.1 and 8.2. Gross beta activity at indicator locations ranged from 0.013 to 0.077 pCi/m3. The associated counting error ranged from 0.001 to 0.006 pCi/m3. Mean quarterly activity is normally calculated using weekly activity over a thirteen (13) week period. Also presented in the tables are the weekly mean values of all the sites as well as the percent relative standard deviation (RSD %) for the data.

Tables 8.3 displays the results of gamma spectroscopy on the quarterly composites of the weekly samples.

PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2013 24

8.2.

Airborne Radioiodine Tables 8.4 and 8.5 present the quarterly radioiodine results. Radioiodine was not observed in any samples.

8.3.

Vegetation Table 8.6 presents gamma isotopic data for the vegetation samples.

No gamma emitting radionuclides were observed in any of the samples.

8.4.

Milk Table 8.7 presents gamma isotopic data for the goat milk samples. No gamma emitting radionuclides were observed in any of the samples.

8.5.

Drinking Water Samples were analyzed for gross beta, tritium, and gamma emitting radionuclides. Results of these analyses are presented in Table 8.8. No tritium or gamma emitting radionuclides were detected in any samples. Gross beta activity ranged from less than detectable to a high of 10.0 pCi/liter. The gross beta activity is attributable to natural (background) radioactive materials.

8.6.

Ground Water Ground water samples were analyzed from two onsite wells (regional aquifer) for tritium and gamma emitting radionuclides. Results obtained from the analysis of the samples are presented in Table 8.9.

No tritium or gamma emitting radionuclides were observed in any of the samples.

8.7.

Surface Water Surface water samples from the Reservoirs and Evaporation Ponds were analyzed for tritium and gamma emitting radionuclides. The two Reservoirs contain processed sewage water from the City of Phoenix and are approximately 45 and 85 acres in size. The three Evaporation Ponds receive mostly circulating water from main turbine condenser cooling and are about 200-250 acres each.

Sample results are presented in Table 8.10.

1-131 was observed in both reservoirs and Evaporation Ponds lB and 2B. The 1-131 levels ranged from 20 pCi/L - 43 pCi/L. 1-131 in these surface water locations is a result of radiopharmaceutical 1-131 in the Phoenix sewage effluent and is not attributable to plant effluents.

Tritium was routinely observed in the Evaporation Ponds. The highest concentration was 1290 pCi/liter. Tritium was not detected in the Reservoirs. The tritium identified in the Evaporation Ponds has been attributed to permitted plant gaseous effluent releases and secondary plant liquid discharges (e.g. condensate overboard discharge, secondary side steam generator drains, secondary plant sumps, demineralizer regeneration waste). The tritium concentrations were compared to historical values and are considered typical for the Evaporation Ponds.

PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2013 25

WRF Influent (Phoenix sewage effluent containing radiopharmaceutical 1-131) samples collected by the WRF were analyzed for gamma emitting radionuclides and tritium. The results, presented in Table 8.10, demonstrate that 1-131 was observed routinely. The 1-131 concentration ranged from less than detectable to 62 pCi/liter. None of the samples analyzed indicated the presence of tritium.

Table 8.10 also presents gamma spectroscopy and tritium measurements of samples collected from Sedimentation Basin 2. This basin collects rain water from site runoff and was dry for most of the year. Low concentrations of tritium were identified in four (4) of ten (10) samples ranging from 341 to 595 pCi/liter. The tritium was attributed to rain washout of plant gaseous effluent releases.

No gamma emitting radionuclides were observed in the samples.

8.8.

Sludge and Sediment 8.8.1.

WRF Centrifuge waste sludge Sludge samples were obtained from the WRF centrifuge and analyzed by gamma spectroscopy. I-131 activity in the sludge is consistent with historical values and, as previously discussed, is due to radiopharmaceuticals in the WRF Influent. The concentration of 1-131 ranged from 123 to 931 pCi/kg.

In-Ill was also identified in the sludge in one sample at 48 pCi/kg. It was previously established that In-Ill is also used in the Phoenix area as a radiopharmaceutical.

Results for WRF centrifuge waste sludge can be found in Table 8.11.

8.8.2.

Cooling Tower sludge Sludge/sediment originating from the Unit 1 and Unit 2 Cooling Towers and Circulating Water canals was disposed of in the WRF sludge landfill during 2013. Sample results can be found in Table 8.11.

8.9.

Data Trends Figures 8.1-8.8 present data in graphical format. Historical data are displayed for comparison where practical.

8.10.

Hard-to-Detect Radionuclide Results Table 8.12 shows the results of the three subsurface samples obtained from 3 tritium monitoring points. These samples were analyzed for hard-to-detect radionuclides (e.g. C-14, Fe-55, Ni-63, Sr-

90) and all results were <MDA. These results indicate that no leaks from plant systems have affected groundwater.

Thermoluminescent Dosimeter (TLD) Results and Data The environmental TLD used at PVNGS is the Panasonic Model 812 Dosimeter. The Model 812 is a multi-element dosimeter combining two elements of lithium borate and two elements of calcium sulfate under various filters.

TLDs were placed in fifty locations from one to thirty-five miles from the PVNGS. TLD locations are shown in Figures 2.1 and 2.2 and are described in Table 9.1. TLD results for 2013 are presented in Table 9.2. Historical environmental gamma radiation results for 1985 through 2013 are presented in graphical form on Figure 9.1 (excluding transit control TLD #45).

Figure 9.2 depicts the environmental TLD results from 2013 as compared to the pre-operational TLD results (excluding sites #41 and #43, as they were deleted and later assigned to a new location, and #46-50, as they had no pre-op TLD at the location for comparison). The site to site comparisons indicate a direct correlation with respect to pre-operational results. It is evident that the offsite dose, as measured by TLDs, has not changed since Palo Verde became operational.

Land Use Census 10.1.

Introduction In accordance with the PVNGS ODCM, Section 6.2, the annual Land Use Census was performed in April 2013.

Observations were made in each of the 16 meteorological sectors to determine the nearest milking animals, residences, and gardens of greater than 500 square feet. This census was completed by driving the roads and speaking with residents.

The results of the Land Use Census are presented in Table 10.1 and discussed below.

The directions and distances listed are in sectors and miles from the Unit 2 containment.

10.2.

Census Results Nearest Resident There was no change in nearest resident status from the previous year. Dose calculations indicated the highest dose to be 0.215 mRem.

Milk Animal There was no change in milk animal status from the previous year. Dose calculations indicated the highest dose to be 0.456 mRem.

Vegetable Gardens There was no change in nearest garden status. Dose calculations indicated the highest dose to be 0.855 mRem.

See Table 10.1 for a summary of the specific results and Table 2.1 for current sample locations.

Figures 10.1 through 10.3 provide graphs depicting historical calculated doses for nearest residents, nearest milk receptor, and nearest garden receptor locations in each sector.

Differences in calculated doses are the result of many variables, including;

" Changes in receptor locations from year to year (proximity to the power plant)

" Changes in local meteorology (wind direction, wind speed, precipitation, temperature)

" Concurrent meteorology at the time of effluent releases

" Exposure pathways PVNGS ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT-2013 60

In 2002 and 2004 the combination of meteorology, milk animal proximity to the plant, and gaseous effluent releases resulted in higher calculated doses in the NNE and NE sectors.

No milk samples have indicated any plant related radionuclides. Additionally, milk animals in the desert environment are normally fed stored feed and are not on pasture. The calculated doses are conservative since they include pastured feed as part of the calculation.

Summary and Conclusions The conclusions are based on a review of the radio assay results and environmental gamma radiation measurements for the 2013 calendar year. Where possible, the data were compared to pre-operational sample data.

All sample results for 2013 are presented in Tables 8.1-8.12 and do not include observations of naturally occurring radionuclides, with the exception of gross beta in air and gross beta in drinking water. Table 11.1 summarizes the ODCM required samples and is in the format required by the NRC BTP on Environmental Monitoring.

1-131 identified in the Evaporation Ponds, WRF Influent, WRF Centrifuge sludge, and Reservoirs is the result of offsite sources and appears in the effluent sewage from Phoenix. The levels of 1-131 detected in these locations are consistent with levels identified in previous years.

Tritium concentrations identified in surface water onsite have been attributed to PVNGS permitted gaseous effluent releases and secondary plant releases. These concentrations are consistent with historical values.

Environmental radiation levels are consistent with measurements reported in previous Pre-operational and Operational Radiological Environmental annual reports, References 1 and 2.

There was no measurable radiological impact on the environment in 2013 resulting from the operation of PVNGS.
