Company for the Palo Verde Nuclear Generating Station (PVNGS)during calendaryear2009in accordance with Aquifer Protection Permit (APP)No. P-100388. The PVNGS, located approximately45 miles west of Phoenix near Wintersburg,Arizona, (Figure1),is a standardizedtriple-unitnuclearpower facility.The site began operations in 1985and consists of an existing electricgeneratingbaseloadplant utilizingnuclearfission for generationof electricalpower. The facilityis situatedon 4,280 acres and consists of three separate, identicalgeneratingunits/reactors. Each reactor is equippedwith three coolingtowers and is capableof independent operation. Followingsteam generator replacementsand thermal uprates in Units 1, 2, and 3, eachunit now has a nominal net electricaloutput of approximately1,346megawatts(MW),for a total plant capacityof about 4,038 MW.

The originalAPP for the sitewasissued by the Arizona Department of EnvironmentalQuality(ADEQ) in December 2003and has undergone multiple revisions. Allreferencesin this report refer to the APP revision dated February 10, 2010 (the Permit).

Section14.0of the Permit provides reporting and recordkeepingrequirements. In addition to self monitoring report forms, operation inspection/log book recordkeeping, and permit violationand alert levelstatus reporting,elements of the annualmonitoring and compliancereport are specified. The followingannual monitoringand compliancereport outline is taken directlyfrom Section 14.4of the Permit:

1. GROUNDWATER MONITORING A.

SUMMARY

TABLES/SPREADSHEETS OF ANALYTICAL RESULTS In accordance with Section 12.4.2.3 of the Permit and the Compliance Schedule in the Permit, transducers have been installed in APP wells listed in Table 17.2-34. Wells containing transducers include piezometers, point of compliance (POC) wells, and alert wells. However, APP-1 and PV-191A do not contain transducers since these wells have been dry since installation. The location and aquifer monitored by each well listed in Table 17.2-34 is presented in Figure 1. It should be noted that PV-201A, PV-202A, PV-203A and PV-204A were abandoned in August 2008.

The sampling plan, approved by ADEQ, contains the following order for sampling monitoring wells at the PVNGS: APP-12, APP-10, APP-9, APP-8, PV-206A, PV-198AR, PV-Q8, APP-3, APP-4R, PV-193A, APP-5, PV-34H, APP-6, PV-14H, APP-13, APP-14, APP-15, PV-195A, PV-R2AR, and APP-7. Section 12.4 of the Permit requests that a description of deviations from the sampling order be included in the annual report.

The following deviations from the sampling order occurred in 2009:

• Groundwater samples from APP-9, APP-10 and APP-12 were collected out of order on January 15, 2009.

All three samples were collected on the same day, but the sample from APP-9 was collected before the samples from APP-10 and APP-12 and the sample from APP-10 was collected before the sample from APP-12.

• Firing range activity impacted the sampling schedules for PV-195A, PV-14H and APP-6. In June 2009, the sample from PV-195A was collected before the samples from PV-14H and APP-6 and the sample from PV-14H was collected before the sample from APP-6. In October 2009, the samples from APP-6 and PV-14H were collected before samples from APP-12, APP-10 and APP-9.

• Groundwater samples from PV-198AR and PV-193A were collected in July and August 2009, respectively. However, these groundwater samples were collected out of order as part of verification sampling.

• Groundwater samples from APP-3 and APP-13 were collected out of order in November 2009. The initial sample from APP-3 was collected on October 29, 2009. However, a second sample was collected from APP-3 on November 3, 2009, to be analyzed for gamma emitting radionuclides (Cesium-134, Cesium-137, Cobalt-60, Iodine-131). The second sample was collected out of order, after PV-193A. The groundwater sample from APP-13 was collected out of order, before PV-34H.

Although there were deviations in the sampling order, samples were collected at the frequency specified by the Permit and the sample order did not adversely affect the groundwater monitoring results.

At a minimum, transducers record groundwater elevations on a daily basis. A table summarizing selected groundwater levels for 2009 is provided in Table 1A-1. The table includes transducer data or manual readings recorded prior to sample collection.

In accordance with Table 17.2-10 of the Permit, POC wells and alert wells are required to be sampled on a quarterly basis for indicator parameters. Tritium is an indicator parameter at all of the POC and alert wells; however, boron and chloride are additional indicator parameters at the shallow alert wells. Analytical results for the indicator parameters are presented in Tables 1A-2 through 1A-21 of this report.

1. GroundwaterMonitoring 2009Annual Monitoring andComplianceReport APPNO.P-100388 Groundwater samples are also collected on a biennial basis (every two years) for the extended list of parameters listed in Tables 17.2-11 through 17.2-20 and Tables 17.2-24 through 17.2-30 of the Permit. In general for 2009, groundwater samples collected in May or June were analyzed for the extended list of parameters for data continuity (biennial sampling occurred in 2008). The associated water quality data for 2009 are presented in Tables 1A-2 through 1A-21 of this report.

The ambient monitoring periods for POC well APP-13 and alert wells APP-14 and APP-15 were completed in August 2009; groundwater samples collected from these wells during November 2009 were analyzed for the quarterly indicator parameters listed in Table 17.2-10. Samples to be collected in 2010 will be analyzed for the extended list of parameters in accordance with Tables 17.2-31 through 17.2-33 of the Permit.

Analytical results for the groundwater samples are compared to alert levels (ALs) and aquifer quality limits (AQLs) specified in the permit, as wellas AWQSs. Exceedances are discussed in Section 1.C of this report.

1. GROUNDWATER MONITORING QUARTERLY SHALLOW GROUNDWATER 'APS AND ANNUAL REGIONAL GROUNDWATER EQUlPOTENTtfAL rVIAPS Cont_urs of the shallow water level data have been completed for each quarter of 2()()9and are presented on Figures 4 through 7. Contours of water levels f(_r the Palo Verde Clay aquifer have also been completed fi)r each quarter of 2009 and are presented on Figures 8 through 11. The groundwater elevation c(mt(mrs wcrc developed using the computer program Surfer. Minor hand drawn edits have been made to certain areas based on historical water level data or interpretation. This approach is considered appropriate for the data set utilized, and the water level data also reflects the subsurface heterogeneity. In general, the shallow water level elevation maps fi)r 20I)9 remain consistent with historical shallow groundwater elevation maps.

In Section 14.4.1 A.ld of the Permit, the completion {_fa Regional Groundwater equip_tentiai map is als(_

requested. Based <)nthe number of wells, the water level complexities created from historical on-site pumping, current off-site pumping, and different well completion depths, contouring of the regi<malaquifer water level elevation data was n<_tcompleted, nor is it considered tcchnicalh' advisable. Historically, based (m regional aquifer water level data collected both on and off site, it has been shown that regional aquifer flow directions are to the south/southwest. This flow direction is similar t_)the natural pre Pk"NGS gr<mndwatcr flow direction with the current flow gradient largely controlled by pumping in the Centennial \\'ash area t()

the south/southwest, and pumping by Duke Energy to the south of the PVN(;S property. The water level elevation data collectcd for the regional aquifer wells (APP-3, APP-6, and PV-216R) has been pr<_videdin Table 1,\ 1 and p(_sted on Figure 12. As the data posted on Figure 12 indicates, the general gr<_undwater flow direction is t(_the south/southwest tit present.

H)-drographs f{)r the monitoring wells listed in Table 17.2 34 of the Permit are provided in Figures 13 thr_mgh 54 with the exception of the fi4lowing wells for the stated reasons:

,\PP-I was dry throughout 2009 and has been dry since 2004.

PV 191A was dr) through_ut 2009 and has been dry since 1985.

1. GROUNDWATER MONITORING PROVIDE TDS AND CHLORIDE CONCENTRATION CONTOUR MAPS FOR THE SHALLOW AQUIFER ON A BiENNiAL BASIS Section 14.4.1.:\. l.e of the Permit requests that annual reports include TDS and chloride concentration contour maps for the shallow aquifer on a biennial basis. Since the site is composed of multiple levels of saturation resulting from infiltration of excess irrigation water when the site was activeh farmed, and based on the heterogeneous nature of the site geology, there is a high degree of both spatial and temporal variahilitv in inor,_amc water quality. These characteristics result in localized water level and water quality conditions.

The water qualib results in particular are not amenable to contouring, nor would the results be technically meaningful. Therefore, rather than prepare contour maps of TDS and chloride concentrations, selected biennial data for TDS and chloride have been presented on l;igures 55 and ,3, respectively.

Biennial TDS data collected from the shallow aquifer wells in 2008 and discretionary TDS data collected fr(ma the shallow aquifer wells in 20il9 are shown on I:Jgure 55. Biennial TDS concentrations in the shalh)w aquifer wells ranged from 3,4()()mg/l_ at APP 12 up to 27 ()0() mg/L at PV-195A.

\s stated in Section 1.C of this report, a chloride concentration map is provided as Figure 3. The figure includes quarterly results for the shallow aquifer wells, Palo \"erde Clay aquifer wells and the regional aquifer wells. In 2()()0, chloride concentrations in the shallow aquifer wells ranged from 950 mg/l. at

\PP 1()up t(J 14,()()()mg/l. at APP 14.

2. IMPOUNDMENT MONITORING LCRS SUf41P MONlTOR)NG RESULTS The leak c(41ection and recoxcry systems (I,CRS) associated with the facility's impoundments are monitored on a daily basis fi)r the presence of fluid. Tile fidlowing I,CRS components are monitorcd in accordance with Tables 17.2 3, 17.2-5, 17.2 8 and 17.2-0 of the Permit:

Three _umps at the 85-acre WSR; Two sumps (north and south collection sumps) at the 45 acre WSR; Two sumps at Evaporation Pond 1; Two sumps at Evaporation Pond 2A and p,v(_sumps at Evaporation Pond 2B/2(I but these impoundments were under construction thr{mghout 2009; and Two sumps at Ewtporation Pond 3A and p,vo sumps at }'_vaporationPond 3B.

The t(_taldaih' volumes of water pumped by sumps at the 45-acre WSR and l-{vaporation P(md 1did not exceed the ,\1_specified in the Permit. However, there was one exceedance of an AI. based on the volume pumped by Sump 2 of the 85-acre WSR on November 24, 2(109. As stated in the five-day written n()tificati_,n letter, dated December 3, 2009, 32,617 gallons were pumped from Sump 2 on November 24, 2009, which exceeds tb,e i\IA of 17,66(/gallons per day. The volume pumped by Sump 2 did not exceed the i\12 of 577,655 gallons per day. More information on this exceedance is provided in Section 2D.

Evap(,rati, m P_md 2 was empty throughout 2009. Therefore, no water was pumped by the sumps associated with Evaporation Pond 2.

Dail) monit_)ring was conducted at both sumps at Evaporation Pond 3,\ throughout 200% daily m(mit(Jring

()f both sumps at Evaporation Pond 3B began on June 9, 20{)9,when the pond was put int{)service. The t{_taldaih' volume ()fwater pumps by Evaporation Pond 3A's and 3B's sumps did not exceed the \l_s specified in the Permit.

A summary tablc of daily sump monitoring activities conducted in 2009 is provided m Table 2A-1.

SUMMARY

OF THE RESULTS OF ALL LINER LEAKAGE In general, the sumps associated with the water storage reservoirs and evaporation ponds pumped intermittently throughout 2009. In 2009, none of the ,'\l_s were cxceeded at the 45-acre \\'SR, Evaporation Pond 1, and Evaporation Ponds 3A and 3B. However, therc was one exceedance of an AI_based on the volume pumped by Sump 2 of the 85-acre WSR on November 24, 2(109. As stated in the five-day written notification letter, dated December 3, 2009, 32,617 gallons were pumped from Sump 2 on Novembcr 24, 2()(!9,which exceeds the AIA _Jf17,660 gallons per day. Volumes pumped on subsequent days were below the :\lJ of 17, 66(! galhms per day. APS began dropping the water level in the 85-acre WSR _m N_vember 1, 2(){)9,prior to the AI,1 exceedance. The 85 acre \X'SRwas about 10 percent full on November 24 as water was transferred to the 45-acre WSR by means of pumps t-loating on barges. It is believed that one of the barges made contact with the liner, causing a tear that resulted in the increased flow to Sump 2. The v_>lumc purnped b\ Sump 2 did not exceed the AI,2 of 577,655 gallons per day.

As summarized on Table 2C-1, maintenance and repair activities occurred at the 85-acre reservoir and Kwlporation Pond 1 during the reporting period. Repairs wcre made t<_all indicated and _bscrved liner defects.

,COOLING TOWER SLUDGE ANALYTICAL RESULTS Cooling tower sludge is required to be characterized prior to disposal in the Sludge Disposal Landfill, on a per disposal event basis. Four cooling tower sludge samples (canal and each of the three towers) were collected from each unit in 2009:

' Samples from Unit 1were collected in February 2009. In 2009, an estimated 216 cubic yards of cooling tower sludge from Unit 1 was disposed.

Samples from Unit 3 were collected in August 2009. In 2009, an estimated 326 cubic yards of cooling tower sludge from Unit 3 was disposed.

Samples from Unit 2 were collected in December 2009. Cooling tower sludge from Unit 2 was disposed in 2010; therefore, the estimated volume will be provided in the 2010 Annual Monitoring and Compliance Report.

All cooling tower sludge samples were analyzed for the parameters listed in Table 17.2-4 of the Permit.

years. :\Is{,, the nitratc-nitritc as N concentrations at APP-3 and PV-14H and fluoride concentrations at PV 195A in 2(1[19are similar to concentrations reported fi_rthese wells in 2008.

These ,\I, exceedances were not associated with discharges from the permitted facilities. Elevated concentrations of boron, chloride, fluoride, nitrate nitrite as N, potassium, and total dissolved solids max bc attributed to previous agricultural land use and/or changing site conditions (such as a decrease in water levels). For cxample, for many shallow aquifer wells, water levels have decreased. Many of th(_sewells arc screened in a silty clay unit and the increase in potassium (a metal commonly found in clay minerals) may again be attributable to the clayey zones that may be intersected as water levels decrease.

In addition, APS has noticed variation in concentrations for some parameters (such as potassium) that c(_rrelate with the laboratory used and/(_r meth(_d used. I_'(_rexample, EPA Meth(_d 20{I.7,a method using inductively-coupled plasma, is greatly affected b} high sodium and total dissolved solids concentrations.

Potassium and sodium are both easily ionizable and this may be contributing to the variability in the results.

EP,\ Meth(Jd 258.1 which is an atomic absorption method was used historically; however, currently, there arc no Ariz(ma-certified laboratories for this method. Alternative appropriate methods for potassium are being investigated with our contract laboratory. It is uncertain whether or not the potassium exceedances in may be within the inherent variability of EPA Method 20{I.7.

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 2009, the following categories of samples were collected by APS:

• Broad leaf vegetation
• Ground water
• Drinking water
• Surface water
• Airborne particulate and radioiodine
• Goat and cow 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. Low level tritium was discovered in subsurface water onsite (not considered potable) in February 2006 at Units 2 and 3. A significant investigation was initiated to determine the source of the water, the extent of the condition, and corrective actions to protect ground water. See Section 2.4 for further discussion.

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. The REMP is performed in accordance with the federal requirements to provide a complete environmental monitoring program for nuclear reactors, and with concern for maintaining the quality of the local environment. The program complies with the requirements of 10 CFR 50, Appendix I, PVNGS Technical Specifications, and with the guidance 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).

This report contains the measurements and findings for 2009. All references are specifically identified in Section 12. The objectives of the REMP are as follows: 1) to determine baseline radiation levels in the environs prior to plant operation and to compare the findings with measurements obtained during reactor operations: 2) to monitor potential radiological exposure pathways to the public; and 3) to determine radiological impacts on the environment caused by the operation of PVNGS. 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). Results of the PVNGS pre-operational environmental monitoring program are presented m 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. P\ ._J(iS ANNUAL RADIOLOGICAL ENVIRONMENTAL ()PERATING REPORT - 2009 2

2. Description of the Monitoring Program APS and vendor organizations performed the pre-operational radiological environmental monitoring program, which began in 1979. APS and vendors continued the program into the operational phase.

2.1. 2009 PVNGS Radiological Environmental Monitoring Program The assessment program consists of routine measurements of environmental gamma radiation and of radionuclide concentrations in media such as air, ground water, 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. Sample analyses were performed by APS at the PVNGS Central Chemistry Laboratory. This laboratory is licensed by the Arizona Department of Health Services (ADHS) to perform radiological analyses. 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 2009 Annual sampling of Evaporation Pond sediment was discontinued based on historical data and the potential to damage the new liners. This sample was not ODCM required and an evaluation of the risk vs benefit to continued sampling was documented in the Corrective Action Program by CRDR #3363010. The Land Use Census identified a new cow milk location within 5 miles and this location was added to the monitoring program. Evaporation Pond #3 (divided into sections 3A and 3B) was built and placed into service. Water from Evaporation Pond #2 was pumped into this pond. Evaporation Pond

              #2 is empty and is undergoing a complete liner replacement.

PV_'NGSANNI _AL IL&DIOLOGI('AL ENVIRONMENTAL OPERATING REPORT - 2o09 3

The following changes implement ODCM Revision 24 and were made as a result of the annual Land Use Census (reference CRDR #3337879);

1. Replaced the Lahti (ODCM Site #47), and Wright (ODCM Site #52), vegetation sample locations with the Batdorf location. Designated Batdorf as Site #47.

     > 2. Added the Rodriguez (cow and goat) and Davis (goat) milk sample locations.

Designated Rodriguez as Site #51 and Davis as Site #52.

3. Retained the Hernandez goat milk location as Site #54, but changed status to supplemental.

Refer to Table 2.1 for a description of all current sample locations (except TLDs). 2.3. REMP Deviations/Abnormal Events Summary During calendaryear 2009, therewere six (6) deviations/abnormalevents with regard to the monitoring program. Refer to Table 2.3 for more detail and any corrective actions taken.

• The air samples at Site #7A were invalid from 9/15 through 9/22
• The air samples at Site #14A were invalid from 11/9 through 11/17
• Evaporation Pond #2 was empty the entire year for liner replacement
• The 1-131 concentration in water exceeded the action level in Evaporation Pond #1 and both Reservoirs
• TLDs at Site #36 were missing in the 3 rd quarter
• The 4mquarter TLD results were delayed for more than 60 days 2.4. Significant Investigation Regarding Ground Water Protection (Follow-up from past reports)

NOTE: Althoughnot part of the REMP, this informationis being provided due to the identificationof low level tritium in the onsite environs (within the Radiological ControlledArea) and heightenedsensitivityto communicatethe potentialto affect ground water. On February 15, 2006 Palo Verde personnel observed water leakage into the Unit 2 Essential Pipe Density Tunnel through the 'B' Spray Pond (SP) supply line penetration seal (documented on Significant CRDR No. 2869959). Low level tritium was identified in this water. It has been determined that the water was not the result of leakage from a plant system, but more likely due to previous operating conditions combined with precipitation. The investigation revealed that Unit 3 had a similar situation. PVNGS initiated OE22651 and follow-up OE24237 to describe the incident of low level tritium at Unit 3 since the concentration exceeded a reporting threshold. P\ ._GS ANNUALRADIOLOGICALENVIRONNIENTA[OPERATINGREPORT- 2O09 4

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 are reported in the PVNGS Annual Radioactive Effluent Release Report (ARERR). PVNGS has implemented a ground water protection program initiated by the Nuclear Energy Institute (NEI). This initiative, NEI 07-07 (Industry Ground Water Protection Initiative - Final Guidance Document, August 2007), provides added assurance that ground water will not be adversely affected by PVNGS operations. The State of Arizona APP provides specific regulatory criteria for ground water protection. P\LN(iS ANNUAL RADIOLOGI('AL ENVIR()NMENTAL ()PERATING REPORT - 2009 5

TABLE 2.3 SUMMARIES OF REMP DEVIATIONS/ABNORMAL EVENTS Deviation/Abnormal Event Actions taken

1. The air samples at Site #7A were invalid from 1. The air sample pump failed during the 9/15 through 9/22 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.

2. The air samples at Site #14A were invalid 2. The air sample pump failed during the from l l/9through 11/17 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.

3. Evaporation Pond #2 was empty the entire 3. The liner is being replaced. Evaporation year for liner replacement Pond #2 was empty all year. When water is added to the pond routine sampling will start.

No action required.

4. The 1-131 concentration in water exceeded the 4. Corrective Action Program document CRDR action level in Evaporation Pond #1 and both #3309449 provides the evaluation conclusion Reservoirs that radiopharmaceutical 1-131 is the cause of the elevated 1-131 concentrations.

Because the 1-131 is not the result of plant effluents, n.__o_o Special Reporting was required. Providing the information in this report meets the requirements of ODCM Section 6.1, Action b. and CRAI #3312804. No further actions are required.

5. TLDs at Site #36 were missing in the 3ra 5. The TLDs at this location were moved across quarter the road as it was determined a school bus stop was now at this location. The TLDs were not missing in the 4_h quarter.

Therefore, moving them across the road has corrected the problem. Relocation of these TLDs will be considered if the problem recurs. No further actions are required at this time. P'_LNGSANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2009 8

The mixture is dark adapted and counted for tritium activity using a liquid scintillation counting system. P'vLNGSANNUAL IL_.DIOLOGICAI. ENVIR()NMENTAL OPERATING REPOR [ - 2009 14

4.6.3. Gross Beta A 200-250 milliliter sample is placed in a beaker. Five (5) milliliters of concentrated nitric (HNO3) acid is added and the sample is evaporated down to about twenty (20) milliliters. The remaining sample is transferred to a stainless steel planchet. The sample is heated to dryness and counted for gross beta in a gas flow proportional counter. 4.7. Soil 4.7.1. Gamma Spectroscopy The samples are sieved, placed in a one-liter plastic marinelli beaker, and weighed. The samples are then counted on a multichannel analyzer equipped with an HPGe detector. The resulting spectrum is analyzed by a computer for specific radionuclides.

5. Nuclear Instrumentation 5.1. Gamma Spectrometer The Canberra Gamma Spectrometer consists of a Canberra System equipped with HPGe detectors having resolutions of 1.73 keV and 1.88 keV (as determined by full width half max with an energy of 0.5 keV per channel) and respective efficiencies of 21.5% and 38.4% (as determined by the manufacturer with Co-60). The Canberra System is used for all gamma counting. The system uses Canberra developed software to search, identify, and quantify the peaks of interest.

5.2. Liquid Scintillation Spectrometer A Beckman LS-6500 Liquid Scintillation Counter is used for tritium determinations. The system background averages approximately 15-17 cpm with a counting efficiency of approximately 40% using a quenched standard. 5.3. Gas Flow Proportional Counter The Tennelec S5E is a low background gas flow proportional counter for gross beta analysis. The system contains an automatic sample changer capable of counting 50 samples in succession. Average beta background count rate is about 1-2 cpm with a beta efficiency of approximately 30% for Cs- 137. P'_.'NGS AN_NUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT - 2009 15

6. 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 2_ 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.

P'_.N(IS ANNUAI.RADIOLOGICALENVIRONMENTALOPERATINGREPORT- 20O9 16

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 LED calculation. P'_.'NGS ANNUAL RADIOLOGIC,_,L ENVIRONMENTAL OPERATING REPORT - 2009 17

The factors governingthe calculation of the LLD and MDAvalues are discussedbelow: I. Sample Size

2. Counting Efficiency The fundamentalquantity in the nleasurementof a radioactivesubstance is the number of disintegrationsper unit time. As with most physical measurementsin analytical chemistry, an absolute measurementof the disintegrationrate 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 disintegrationsper 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 surroundingmaterials, 2) cosmic radiation, and 3) the natural radioactivity in the counter material itself. The background countingrate will depend on the amounts of these types of radiation and the sensitivityof the counterto 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 disintegrationconstant is one of the basic characteristics of a specific radionuclideand 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 duringtransit time and sampleprocessing.

8. 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 (2_) 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 report. Results and interpretation of the data for all of the samples analyzed during 2009 are presented in the following sections. Assessment ofpre-operational and operational data revealed no changes to environmental radiation levels. The only nwasurable impact on the en_qronment in 2009 was the low level tritium discovered in subsurface water onsite in the RCA in 2006. See Section 2.4 fi_r specific infi_rmation. 8.1. Air Particulates Weekly gross beta results, in quarterly fonnat, are presented in Tables 8.1 and 8.2. Gross beta activity at indicator locations ranged from 0.013 to 0.080 pCi/m 3. The associated counting error ranged from 0.001 to 0.004 pCi/m 3. 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. The gross beta activity is attributable to natural (background) radioactive materials. The findings are consistent with pre-operational baseline and previous operational results. The results are summarized in Table 11.1. Table 8.3 displays the results of gamma spectroscopy on the quarterly composites. No Cs-134 or Cs-137 was observed.

8.2. Airborne Radioiodine Tables8.4 and8.5 presentthe quarterlyradioiodineresults.Noairborneradioiodinewas observedin anyofthe samples. 8.3. Vegetation Table 8.6 presents gamma isotopic data for the vegetation samples. No gamma emitting radionuclideswere observed in any of the samples. 8.4. Milk Table 8.7 presents gamma isotopic data for the goat milk samples. No gamma emitting radionuclideswere 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 5.5 pCi/liter (Gavette residence, August composite). The gross beta activity is attributable to natural (background) radioactive materials. 8.6. Ground Water Ground water samples were analyzed for tritium and gamma emitting radionuclides. Results obtainedfrom 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. Evaporation Pond #3 was constructed in 2008 to allow for re-lining of the older ponds. Evaporation Pond #2 was pumped into Evaporation Pond

     #3 (sections 3A and 3B) and will be relined first. Results are presented in Table 8.10. 1-131 was observed in the Evaporation Ponds in two (2) samples (15 to 20 pCi/liter) and four (4) of the Reservoir samples (13 to 32 pCi/liter). 1-131 in these surface water locations is a result of radiopharmaceutical I-131 in the Phoenix sewage effluent.

Tritium was routinely observed in the Evaporation Ponds. The highest concentration in Evaporation Pond #1 was 1224 pCi/liter and the highest concentration in Evaporation P\LNGSANNUALRADIOLOGICALENVIRONMENTALOPERATINGREPORT- 20O9 26

Pond #3 was 991 pCi/liter. Evaporation Pond #2 was empty the entire year due to liner replacement. 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. WRF Influent (Phoenix sewage effluent containing radiopharmaceutical1-131) 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 highest 1-131concentrationwas 74 pCi!liter.None of the samples analyzed indicatedthe presenceof tritium. Table 8.10 also presents gamma spectroscopy and tritimn measurements of samples collected from SedimentationBasin #2. This basin collects rain water from site runoff and was dry for most of the year. No tritium or gamma emittingradionuclides 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. 1-131 activity in the sludge is consistent with historical values and, as previously discussed, is due to radiopharmaceuticals in the WRF Influent. 1-131 was present in all forty-nine (49) samples ranging from 387 to 1670 pCi/kg. In-Ill was also identified in the sludge in 3 of the 49 salnples. The highest concentration was 97 pCiikg. It was previously established that In-I 11 is also used in the Phoenix area as a radiopharmaceutical. Resultsfor WRFcentrifugewastesludgecanbe foundinTable8.11. 8.8.2. Cooling Tower sludge Sludge/sediment originating from the Unit 3 Cooling Towers and/or Circulating Water canals was disposed of in the WRF sludge landfill during 2009. Sample results can be found in Table 8.11. 8.9. Data Trends Figures 8.1-8.5present data in graphicalformat. Historicaldata are displayedfor comparison wherepractical.

9. Thermoluminescent Dosimeter (TLD) Results and Data The environlnental TLD used at PVNGS is the Panasonic Model 812 Dosimeter. The Model 812 is a multi-element dosimeter Colnbining two elements of lithiuna borate and two elements of calcimn sulfate under various filters.

TLDs were placed in forty-nine 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 2009 are presented in Table 9.2. Historical environmental galmna radiation results for 1985 through 2009 are presented in graphical form on Figure 9.1 (excluding transit control TLD #45). Figure 9.2 depicts the environmental TLD results from 2009 as compared to the pre-operational TLD results (excluding sites #41, #43, and #46-50 as they were deleted (and later assigned to a new location) or 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. P'v,'NGSANNUALRADIOLOGICALENVIRONMENTALOPERATINGREPORT - 2009 49

10. Land Use Census 10.1. Introduction In accordance with the PVNGS ODCM, Section 6.2, the annual Land Use Census was performed within five miles of Unit 2 containment in April 2009.

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 were _ro (2) changes in nearest resident status. Dose calculations indicated the highest dose to be 0.229 mrem. Milk Animal There were five (5) changes in milk animal status. Dose calculations indicated the highest dose to be 0.872 mrem. Vegetable Gardens There were four (4) changes in nearest garden status. Dose calculations indicated the highest dose to be 0.332 mrem. See Table 10.1for a sunmaaryof the specificresults and Table 2.1 for current sample locations. P\ .'NGS ANNUAL RAD1OLOGI(2AL ENVIRONMENTAL OPERATING REPORT - 2009 55

11. Summary and Conclusions The conclusions are based on a review of the radio assay results and environmental gamma radiation measurements for the 2009 calendar year. Where possible, the data were compared to pre-operational sample data.

All sample results for 2009 are presented in Tables 8.1-8.11 and do not include observations of naturally occurring radionuclides, with the exception of gross beta in air and gross beta in drinkin¢ water. Table 11.1 summarizes the ODCM required samples and is in the format required by the NRC BTP on Environmemal Monitoring. 1-131 concentrations identified on occasion 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 I-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. The only measurable impact on the environment in 2009 was the low level tritium discovered hi subsurfiwe water onsite in tile Radiologieal Controlled Area hi 2006.

2009Annual Monitoring andComplianceReport APPNO.P-100388 C1 - VERTICAL TREND ANALYSIS Section 14.4.1 A.1 of the Permit states "Using cross-sections of 3-D models, the report shall assess downward concentration trends for indicator parameters and AWQS constituents, if any, and shall consider such trends in combination with topography of the uppermost surface of the aquitard." In previous versions of the Permit, indicator parameter analytical results from shallow aquifer A column wells such as PV-14H, were compared with the analytical results from nearby shallow aquifer deep B column wells such as PV-14HB. (Typically, the A column wells have a longer screened interval than the B column wells. The depth of the bottom of the A and B column wells are generally the same, but the B column wells have a shorter screened interval across the same portion of the aquifer.) The reported B column indicator parameter values were then compared with A column well indicator parameter values as part of the vertical trend analysis. Later modifications of the Perrmt eliminated the requirement to sample the shallow aquifer deep B column wells. As such, for 2009 there were no A and B column well pairs sampled where vertical differences in groundwater quality could be evaluated, therefore a similar downward concentration trend analysis for indicator parameters could not be conducted. However, there were shallow aquifer and nearby Palo Verde Clay aquifer monitoring wells sampled in three locations at the PVNGS site. The three well pairs, the screened intervals monitored and the boron and chloride indicator parameter results are presented in Table C-1. As can be seen in the results, it is evident that chloride concentrations in the shallow and Palo Verde Clay aquifers differ by at least one order of magnitude, and are much higher in the shallow aquifer. Boron concentrations for the two aquifers are significantly different, also generally much higher in the shallow aquifer. This data helps demonstrate that due to the vetT heterogeneous, low permeability, free-grained material represented by the Middle Fine-Grained Unit, vertical migration of groundwater at the site is very limited.
