EXECUTIVE SUMMARY

During the year 2006, a Radiological Environmental Monitoring Program (REMP) was

conducted for the Diablo Canyon Power Plant (DCPP) to assess the levels of radiation or radioactivity in

the environment. More than 1000 samples were collected (including TLDs) over the course of the

monitoring period, with over 2800 radionuclide or exposure rate analyses being performed.

This report contains results from the operational Radiological Environmental Monitoring

Program (REMP) for Diablo Canyon Power Plant (DCPP) compiled for the period January 1, 2006,

through December 31, 2006. This program is conducted in accordance with DCPP Program Directive

CY2, "Radiological Monitoring and Controls Program," and RP 1 .ID 11, "Environmental Radiological

Monitoring Procedure."

The types of samples (matrix ID) collected for this monitoring period are as follows;

Air Particulate (AP) Air Cartridges (AC) For Iodine Monitoring,

Direct Radiation (TLD's) Milk (MK) Meat (MT) Vegetation (VG)

Drinking Water (DW) Ground Water (GW) Surface Water (SW) Aquatic Vegetation (AV)

Fish (FH) Mussels (IM) Sediment (SD) Soil/Sand (SL)

The results of the 2006 REMP showed no unusual findings from plant operations. These results

were also compared to preoperational data and showed no unusual trends. The operation of DCPP had no

significant radiological impact on the environment.

The ambient direct radiation levels in the DCPP environs did not change and were within the

preoperational range.

Plant operations had no significant impact on airborne radioactivity in the environment.

No plant related radionuclides were detected in surface water samples except that Nickel-63 was

detected in one water sample collected at Diablo Cove (DCM) and Iron-55 was detected in one water

sample at the plant outfall (OUT). The plant had no significant impact on surface water.

Food crops, milk, meat, and drinking water samples detected only naturally occurring

radioactivity; and therefore, there was no impact from plant operation.

Marine samples contained only naturally occurring radionuclides.

Ground water monitoring data is collected in accordance with the nuclear industry NEI

Groundwater Protection Initiative. Concentrations of tritium were detected in three monitoring wells

Ibeneath the DCPP power block. These levels of tritium were all below the EPA drinking water standard Iof 20,000 pico curies per liter. DCPP is in the process of trending these monitoring wells to obtain data.

At the printing of this report, this tritium is most likely coming from the rain washout of gaseous tritium Iexiting the plant vent system. It should be noted that studies of the DCPP site indicate that any

groundwater (subsurface) flow beneath DCPP is not used as a source of drinking water. This groundwater

flow discharges into the Pacific Ocean.

Prior to 2006, DCPP utilized an "in-house" environmental lab for sample analysis. That 3environmental lab was Technical and Ecological Services (TES) located in San Ramon, California. At the

beginning of 2006, DCPP REMP changed it's environmental lab to General Engineering Labs (GEL) 3located in Charleston, South Carolina. All REMP sample analyses in 2006 were performed by GEL.

1.0 INTRODUCTION

Diablo Canyon Power Plant (DCPP) consists of two Westinghouse pressurized water reactors.

Unit 1 began commercial operation in 1985, and Unit 2 began commercial operation in 1986.

Radiological Environmental Monitoring Program (REMP) samples are collected by DCPP REMP

personnel and sent to General Engineering Labs in Charleston, South Carolina for analysis. Fish (except

market fish) and ocean sediment samples are collected by contract divers of Tenera Environmental and

given to DCPP REMP personnel for shipment to GEL. Market fish samples are collected by local

commercial fishermen and then purchased in one of two local fish markets by DCPP REMP personnel for

shipment to GEL. Direct radiation analyses were conducted by DCPP REMP personnel and the DCPP

Thermoluminescent Dosimeter (TLD) Lab.

DCPP sends replicate samples of milk (5F2), drinking water (DWI), outfall water (OUT), Diablo

Creek (5S2), vegetative crops (7G1), fish (DCM), sediment (DCM), and kelp (DCM) to the California

Department of Health Services (CDHS) lab as part of a State cross check program. Other pathways

monitored independently by the CDHS are direct radiation and air sampling

I2.0 PROGRAM DESIGN I

The Radiological Environmental Monitoring Program (REMP) for the Diablo Canyon Power Plant

(DCPP) was designed with the following specific objectives in mind. These objectives will continue to be

in force, to varying degrees, throughout facility operation.

To provide an early indication of the appearance or accumulation of any radioactivematerial in the environment caused by facility operation. Preoperational data is also usedin this comparison. ITo provide assurance to regulatory agencies and the public that the station'senvironmental impact is known and within anticipated limits.

To provide standby monitoring capability for rapid assessment of risk to the generalpublic in the event of unanticipated or accidental releases of radioactive material.

The environmental media selected were based on the critical dose pathways of the radionuclides 3from the environment to man. They included the following: direct radiation, air, water, fish, ocean

sediment, and invertebrates. Supplemental samples such as algae, kelp, local agricultural crops, recreational 3beach sand, groundwater, and milk were also collected. The sampling locations were determined by land

use, site meteorology, and local demographics. Guidance for this monitoring program is provided by the 3Radiological Assessment Branch Technical Position on Radiological Environmental Monitoring, Revision

1, November 1979 5The detailed sampling requirements of the REMP are given in Table 2.1 of this report. The

locations actually monitored for the period are shown in Appendix A of this report. Any deviations from 3the REMP sampling schedule / requirements are documented in section 4.0 of this report.

2.1 MONITORING ZONES

The REMP is designed to allow comparison of levels of radioactivity in samples from thearea possibly influenced by DCPP to levels found in areas not influenced by the facilityoperations. Areas with the potential to be influenced by facility operations are called"indicator" stations, and areas with sufficient distance from the plant that are not likely to beinfluenced by facility operations are called the "control" locations. The distinction betweenthe two zones is based on relative direction from the plant and distance. Analysis of surveydata from the two zones aids in determining if there is a significant difference between thetwo areas. It can also help in differentiating between radioactive releases and seasonalvariations in the natural environmental background.

2.3 DESCRIPTIONS OF REMP MONITORING

2.3.1 Direct Radiation

Direct ambient radiation was measured at 31 stations in the vicinity of DCPP usingPanasonic UD814 TLD badges. The TLD badges had valid element correctionfactors (ECF), were calibrated using a NIST-traceable cesium-137 source, wereannealed prior to placement, and were sealed in watertight packaging. Thesebadges were replaced on a quarterly basis.

The field TLD badge packets were prepared and processed by DCPP personnel andthe DCPP TLD Lab. Control badges were carried with the field badges to measureany dose received during transit. The location, date, and time of exchange wererecorded on a log sheet which accompanied the field badges. The net exposure wasreported over a standard 90 day quarter

2.3.2 Airborne Radioactivity

Air particulate and radioiodine sampling were performed weekly at six indicatorstationsý MT1, 0S2, 1SI, 7D1, 8S1 and 8S2. Air particulate and radioiodinesampling was performed weekly at one control station: 5F1.

Constant flow air samplers were used to draw air through paper filters to collectair particulates and through triethylenediamine (TEDA) impregnated charcoalcartridges to collect radioiodine. The air samplers were set at a flow rate of 1.5standard cubic feet per minute. The air samplers were located approximately onemeter above the ground. The sample volumes were determined by F&JCorporation model DF-l flowmeters (corrected to standard temperature and

Ipressure, STP) which are installed downstream of the sample head. At the end of Ithe sampling period (weekly), the filter and cartridge were collected. Allnecessary data regarding the air volume readings, flowrate, sampler time on andoff, date of collection, and sampler location were recorded and submitted to GEL Ialong with the samples for analysis.

Approximately 72 hours after sampling (to allow for radon and thoron daughter 3decay), the filter papers collected from the field were placed on individualplanchets and counted for gross beta activity in a low background, thin windowgas proportional counter. Gamma isotopic analysis was then performed on Iquarterly composites of the filters (by location) to determine the activityconcentration of gamma emitting isotopes.

The TEDA impregnated charcoal cartridges were counted for each weekly Isampling period at each location for gamma isotopic analyses to determine theradioiodine concentration. 3

2.3.3 Waterborne

Water samples (drinking water, surface water, and groundwater) were collectedat the frequencies shown in Table 2.1 IOcean surface water samples were collected at Diablo Cove (station DCM),Rattlesnake Canyon (station 7C2), and at the plant Outfall (station OUT). IDrinking water samples were collected from Diablo Creek Weir (station 5S2),Diablo Creek Outlet (station WN2), Blanchard Spring (station 1A2), and fromthe DCPP drinking water system (station DWI). Drinking water was alsocollected from a control station located in San Luis Obispo at the OffsiteEmergency Lab (station OEL).

Supplemental groundwater samples were collected from Water Well 02.

Supplemental monitoring well samples were collected from Observation Wells01 & 02, and a french drain system labeled Drywell 115. These wells are locatedin close proximity to the facility power block structures. 3After collection, the samples were securely sealed and labeled with sample type,location, date, time of collection, and the person performing the collection andsent to GEL for analysis.

2.3.4 Marine Biological, Beach Sand, and Ocean Sediment

The REMP requires only one sample of rockfish (family Sebastes ), one sample ofperch (family Embiotocidae), and one sample of mussels (family Mytilus) fromindicator station DCM and control station 7C2. All other marine samples collectedare considered supplemental. These supplemental marine samples included, butwere not limited to, the following: intertidal algae, kelp, and market fish. Theintertidal samples (algae and mussels) were collected by DCPP personnel duringlow tidal conditions. Kelp was collected quarterly by DCPP personnel from the Ioffshore kelp bed in the vicinity of the plant. Quarterly samples of fish and anannual sample of ocean bottom sediment were collected from the plant environs by

9

contracted divers (TENERA Environmental). The Tenera divers fillet the fish andleave a small portion of skin for identification. Beach sand was collected by DCPPpersonnel between the high and low tide boundaries at nearby recreational beaches.Fish caught locally by commercial fishermen were purchased from two local fishmarkets (Avila Beach Pier and Morro Bay).

All samples were subject to unavailability due to seasonal fluctuations orunfavorable sampling conditions. The above samples were sealed in plastic bagsimmediately upon collection. Mussels are sent to GEL in-shell where GELpersonnel remove the meat & internal organs for analysis. Only edible portionsof the fish were analyzed (fish fillets). The samples were labeled with sampletype, location, date, time of collection, and individual performing the collection.The samples were then frozen (to prevent spoilage odor) before they were sent toGEL for analysis.

2.3.5 Food Crops

The REMP requires broadleaf vegetation to be collected in the nearest off-sitelocations of the highest calculated annual average ground level D/Q (dispersionparameter). There is no broadleaf vegetation available that satisfies thisrequirement. However, representative samples of food crops in season werecollected monthly from supplemental stations: Cal Poly Farm (5F2), KawaokaFarm in Arroyo Grande (7G 1), Mello Farm (7C1) along the site access road, anda quarterly household garden (6C 1).

The monthly samples were collected by DCPP personnel and sealed immediatelyin plastic bags. The quarterly household garden sample (6C 1) is provided toDCPP personnel by the land occupant (due to access difficulty and privacy). Thesamples were labeled with sample type, location, collection date, collection time,and the individual performing the collection. The samples were normally frozenbefore they were sent to GEL for analysis (to prevent spoilage odor).

2.3.6 Milk

There are no animals within the vicinity of the plant that are utilized for milkconsumption by humans. However, supplemental samples of cow milk werecollected monthly from Cal Poly Farm (5F2) which is approximately 13 milesfrom DCPP. Two 1-gallon plastic containers of milk were collected eachsampling period by DCPP personnel. Forty grams of sodium bio-sulfitepreservative were added to each gallon of milk sample. The containers weresealed and shaken thoroughly to distribute the preservative. The containers werelabeled with sample type, location, collection date, collection time, and theindividual performing the collection. The samples were then sent overnightexpress to GEL for analysis

TABLE 2.3 (Continued)

Table NotationsFor a particular measurement system, which may include radiochemical separation:

LLD =4.66Sb

E x V x 2.22 x Y x exp(-Xt)

Where:LLD = the "a priori" the lower limit of detection as defined above (as pCi per unit mass or

volume)Sb = the standard deviation of the background counting rate or of the counting rate of a blank

sample as appropriate (as counts per minute)E = the counting efficiency (as counts per transformation)V = the sample size (in units of mass or volume)

2.22 = the number of transformations per minute per pico-curieY = the fractional radiochemical yield (when applicable)k = the radioactive decay constant for the particular radionuclidet = the elapsed time between sample collection (or end of the sample collection period) and

time of counting

The value of Sb used in the calculation of the LLD for a detection system will be based on the actualobserved variance of the background counting rate or of the counting rate of the blank samples (asappropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for aradionuclide determined by gamma-ray spectrometry, the background will include the typicalcontributions of other radionuclides normally present in the samples (e.g., potassium-40 in milk samples).Analyses will be performed in such a manner that the stated LLDs will be achieved under routineconditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence ofinterfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In suchcases, the contributing factors will be identified and described in the Annual Environmental RadiologicalOperating Report.

Typical values of E, V, Y and t should be used in the calculation. It should be recognized that the LLD isdefined as a prori (before the fact) limit representing the capability of a measurement system and not as aposteriori (after the fact) limit for a particular measurement.

3.0 RADIOLOGICAL DATA- SUMMARY OF TABLES

This section summarizes the analytical results of the environmental samples, which were collected duringthe monitoring period. The results, shown in Appendix A, are presented in a format similar to thatprescribed in the NRC's Radiological Assessment Branch Technical Position on Environmental Monitoring.The results are ordered by sample media type and then by radionuclide, and are displayed separately.

Each table is nuclide specific, and the total number of analyses for that radionuclide during the monitoringperiod, are provided. Additionally, the number of measurements which exceeded the Reporting Levels(NRC Notification Level) found in Table 2.4 of this report are provided. The first column lists the mediumor pathway sampled during the period. The second column lists the nuclides analyzed and number ofsamples performed. The third column provides the required Lower Limit of Detection (LLD) forradionuclides that have detection capability requirements as specified in Table 2.3 of this report. The sixthand seventh columns contain the mean and average results for locations. The eighth column contains thenumber for reportable occurrences for the location pathway. Occasionally, the required LLD is not met. Anexample of this occurrence might be due to hold times between sampling and analysis. Such cases, if any,are addressed in Section 4.0 of this report

Additionally, the tables of Appendix A provide the mean of all sample results analyzed for the specifiedradionuclide/ media type, the range, and the number of samples that were considered to have detectableactivity of all the samples counted.

" The filter code "U" indicates that no detectable activity was identified in the sample for the nuclideanalyzed, "UI" indicates an uncertainty in nuclide identification during gamma isotopic analysis,"UUI" indicates a combination of the U & UI. A filter code of "H" means that the analyticalholding time was exceeded.

" The mean and range (minimum detectable and maximum detectable concentrations) valuesconsist of detectable concentrations only.

* The number of detectable measurements and the total number of measurements. For example,(4/20) would indicate that 4 of the 20 samples collected, for that sample type and thatradionuclide, contained detectable radioactivity.

A sample is considered to yield a "detectable measurement" when the concentration exceeds three times itsassociated standard deviation.

The radionuclides reported in this section represent those that: 1) had an LLD requirement in Table 2.3 ofthis report, or a Reporting Level listed in Table 2.4, or 2) were of specific interest for any other reason. Theradionuclides routinely analyzed and reported for a gamma spectroscopy analysis are: Ac-228, Ag-10 lOn,Be-7, Ce-144, Co-57, Co-58, Co-60, Cr-51, 1-131, Cs-134, Cs-137, Ba-140, La-140, Fe-59, K-40, Mn-54,Nb-95, Ru-103, Rh-106, Sb-124, Sb-125, Zn-65 and Zr-95.

Data from direct radiation measurements made by TLD are also provided in Appendix A in a similar formatdescribed above. Actual quarterly TLD results are listed in Appendix B.

4.0 ANALYSIS OF ENVIRONMENTAL RESULTS

4.1 REMP SAMPLING VARIANCE / DEVIATIONS HIThe DCPP Radiological Environmental Monitoring Program allows for deviations in the REMP samplingschedule "if samples are unobtainable due to hazardous conditions, to seasonal unavailability, or tomalfunction of sampling equipment." Such deviations do not compromise the program's effectiveness andare normally anticipated for any radiological environmental monitoring program.

The DCPP REMP includes both required and supplemental samples. This section describes the variances iwith the required samples and describes some of the supplemental sampling during the year.

During 2006, the DCPP REMP "a-priori" LLD for tritium in water was reduced from 2,000 pico-curiesper liter to 400 pico-curies per liter. This change was incorporated into the Offsite Dose CalculationManual (ODCM). Tritium, Strontium-89, Strontium/Yitrium-90, Iron-55, and Nickle-63 were added tomany sample pathway analyses.

SAMPLES LOST IN SHIPMENT FROM DCPP TO GEL IREMP samples are shipped from DCPP Avila Beach, California to GEL in Charleston, South Carolina.Sampling was conducted in accordance with Table 2.1 and provided to FedEx for shipment to GEL. Thefollowing samples did not arrive at their final destination (GEL) and were lost during shipment.

Mussels were collected from DCM, 7C2, and POS on 7-11-06. These mussels were provided to FedEx forshipment on 7-12-06. The mussels were lost by the carrier in Charlotte, North Carolina on 7-18-06 (see IFedEx tracking # 035699710004901).

Vegetation was collected from 7C 1 on 12-5-06. The vegetation was provided to FedEx for shipment on12-5-06. The vegetation was lost by the carrier in Los Angeles, California on 12-7-06 (see FedEx tracking# 035699710006592).

It should be noted that mussel and vegetation sampling at these locations prior to and after these Uoccasions listed above in 2006 have not detected any radionuclides related to DCPP. Additionalreplacement sampling was not conducted due to the event discovery exceeding the 25% variance forreplacement sampling.

AIRBORNE RADIOACTIVITYThe mean percent availability for all on-site and off-site air samplers was 99.8 percent. This means, onaverage, all air samplers were up and running 99.8 percent of the time. The remaining 0.2 percent can beattributed to filter changeout and calibration processes.

MARINE AND TERRESTRIAL SAMPLESAll marine samples were collected as scheduled (including allowable variation) except for musselsamples from Station PON. Mussels were not collected from PON during the second, third, and fourthiquarters due to small size and small numbers of mussels available during these sampling periods. This hasbeen an ongoing issue for Station PON. It should be noted that PON mussel sampling is supplemental.

In August of 2006, the ODCM was revised to reduce the sampling frequency for mussels at Station PONfrom quarterly to annually. This change will allow continued monitoring of this species with reducedimpact on the mussel population at that location.

Page 30: Diablo Canyon, Units 1 and 2 - 2006 Annual Radiological ... · Diablo Canyon Power Plant, Units 1 and 2, submitted in accordance with Technical Specification 5.6.2. The enclosure

All terrestrial samples were collected as scheduled (including allowable variation).

The California Department of Fish and Game has issued regulations prohibiting the collection of abalonealong the central and southern coast of California. PG&E considers is unlikely that collection of abalonewill be allowed in the DCPP environs in the near future. Note that the sampling of abalone was previouslyperformed and is supplemental to the REMP.

OCEAN SURFACE WATERThe July ocean surface water samples from DCM, OUT, and 7C2 were damaged in shipment. Additionalsamples at these locations were taken on 8-2-06 to meet the July timeframe. A twenty five percentvariance is allowed to meet sampling timeframes.

REPLICATE SAMPLESReplicate sampling was added to the REMP for program strength. Replicate samples were taken fromMontana de Oro beach sand (6-30-06), Cambria beach sand (6-30-06), Cambria beach sand (9-1-06), andDiablo Creek 5S2 water (12-20-06). The results of the analyses were within expected correlation.

4.2 COMPARISON OF ACHIEVED LLDS WITH REQUIREMENTS

Table 2.3 of this report gives the required "a priori" Lower Limits of Detection (LLDs) forenvironmental sample analyses required by the DCPP Radiological Environmental Monitoring IProgram. Occasionally an LLD is not achievable due to situations, such as hold times betweensampling and analysis. In such a case, a discussion of the situation is provided.

For each analysis having an LLD requirement, criteria for the calculated "a priori" (before thefact) LLD were met during the sampling and analysis process. Meeting these process criteriasatisfies the "a priori" LLD requirements. The "a posteriori" (after the fact) LLD for that analysis Iwas also compared with the required "a priori" (before the fact) LLD. This comparison was alsosatisfied. It should be noted that the "a posteriori" (after the fact) LLD is normally referred to asthe Minimal Detectable Concentration (MDC) on the GEL analysis reports.

On one occasion, a milk sample (9-5-06) 1-131 LLD was not met due to exceeding the holdingtime for sample analysis. The 9-5-06 sample 1-131 MDC was 1.06 pCi/1 while the LLD was 1.00pCi/I. Milk was re-sampled on 10-3-06 and sent to GEL for analysis. This additional sample met Ithe 1-131 LLD and satisfied the September monthly timeframe due to the 25% variance allowedin REMP sampling.

All samples analyzed met the specific "a priori" LLD requirements during this monitoring period.

4.3 COMPARISON OF RESULTS AGAINST REPORTING LEVELS

Notification is required (report to the NRC within 30 days) whenever a Reporting Level in Table2.4 of this document is exceeded. Reporting Levels are the environmental concentrations that relateto the ALARA design dose objectives of 10 CFR 50, Appendix I. It should be noted that Ienvironmental concentrations are averaged over calendar quarters for the purposes of thiscomparison, and that Reporting Levels apply only to measured levels of radioactivity due toeffluents.

No Reporting Levels were exceeded during this monitoring period. I4.4 DATA ANALYSIS BY MEDIA TYPE

The REMP data for each media type is discussed below. Whenever a specific measurement resultis presented, it is given as the concentration at the 95% confidence level. A sample is considered toyield a "detectable measurement" when the concentration exceeds three times its associatedstandard deviation. 34.4.1 Direct Radiation

Direct radiation is continuously measured at 31 locations surrounding DCPP usingthermoluminescent dosimeters (TLDs). These 31 locations are made up of 29 indicator stations &2 control stations. These dosimeters are collected every calendar quarter for readout at the DCPPTLD Lab. The results are trended with preoperational and historical operating values for adversetrends. No adverse trends were noted in 2006 as indicated by the graph that follows.

4.4.2 Airborne Radioactivity

Air particulate and radioiodine samples were collected weekly from six indicator stations (MT I,OS2, IS1, 7D1, 8S1, and 8S2) in the DCPP environs and one control station (5F1). A total of364 air particulate filters and 364 iodine cartridges were collected and analyzed. The datacollected for the air-sampling program is summarized in Appendix A.

Gross beta activity was detected in almost every weekly air particulate sample collected from allindicator and control stations. Comparison of the data showed that the mean values of gross betaactivities for the indicator stations were consistent with those obtained for the control station andhistorical trending. The gross beta activities detected at the air sampling stations are tabulated inAppendix A.

Gamma isotopic analyses were performed on quarterly composites of the air particulate filtersfrom each station. All samples collected during the monitoring period contained only naturallyoccurring radioactivity.

A total of 364 iodine cartridges were analyzed for iodine- 131. No Iodine- 131 was detected in anyof the iodine cartridges.

4.4.3 Drinking Water, Ocean Surface Water, and Groundwater

Drinking WaterDrinking water samples are collected from stations DWl, 5S2, WN2, 1A2, and at OEL (OEL is acontrol location). The samples are analyzed for gamma emitters, gross beta, tritium, Sr-89, Sr/Y-90, Iron-55, and Nickle-63. Iodine-131 is analyzed by ion exchange procedures.

Additional water sources were added to the REMP in 2006. Diablo Creek Outlet (WN2) wasadded to detect radionuclides from any possible source of subsurface flow from the DCPP powerblock into the creek before discharging into the ocean. It should be noted that the WN2 samplepoint is downstream of the 5S2 sample point for Diablo Creek. One sample collected at WN2 on5/19/06 indicated the presence of Strontium-90 at a concentration of 0.887 pCi/L. This result wasslightly above the detection limit, within environmental background levels, and within thestatistical error for analysis. It should also be noted that Strontium-90 has not routinely beendetected in the power block monitoring wells which supports environmental or statisticalprobabilities. No other plant related isotopes were detected at WN2.Blanchard Spring (1A2) is located approximately 1.5 miles NNW of the plant and suppliesdomestic water to a permanent residence. No plant related isotopes were detected at 1A2.

Of the samples collected during the monitoring period, no plant related radionuclides weredetected in any of the samples.

Ocean Surface WaterOcean surface water samples are collected monthly from stations OUT, DCM, and at 7C2 (7C2 isa control location). The samples are analyzed for gamma emitters, gross beta, tritium, Sr-89,Sr/Y-90, Iron-55, and Nickle-63.

One sample from Diablo Cove (DCM) collected on 8-11-06 detected Nickle-63 at 38.6 picocuries per liter with an error of 16.6 pico curies per liter. The MDC for this sample was 26.3 picocuries per liter.

One sample from the plant outfall (OUT) collected on 11-2-06 detected Iron-55 at 152 pico curiesper liter with an error of 99.7 pico curies per liter. The MDC for this sample was 137 pico curiesper liter.

No other plant related radionuclides were detected in any of the samples.

The results of the water samples collected from both the indicator and control stations aresummarized in Appendix A.

Ground WaterAs part of the nuclear industry NEI Groundwater Protection Initiative, DCPP began samplingvarious water sources in 2006. These sources included onsite monitoring wells, aquifer wells,creeks, ponds, and a water spring.

Various water bodies were sampled in the surrounding county to establish background levels.These additional samples were: Morro Creek, Coon Creek, Mello Pond, and Northwest Pond.Only naturally occurring isotopes were detected in the samples analyzed.

ITwo groundwater aquifer wells are available within the plant site; Water Well 01 and Water Well I02. These wells are located about 115' above and to the east of the power block. Water Well 01is abandoned and the well pump is inoperable. Water Well 02 was sampled and only naturallyoccurring isotopes were detected.

Three subsurface monitoring wells are located within the plant protected area and in proximity tothe containment structures, spent fuel pools, and auxiliary building (plant power block). These Imonitoring wells are labeled Observation Well 01, Observation Well 02, and Drywell 115. These

monitoring wells contained low levels of tritium and are currently in trending processes toestablish well characteristics. This tritium is most likely coming from the rain washout of gaseous Itritium exiting the plant vent system. All of these three monitoring wells were below themaximum concentration level (MCL) established by the U.S. Environmental Protection Agency(EPA) for tritium (20,000 pico curies per liter). Further discussion of radionuclides detected inthese monitoring wells is provided in Section 5.2 of this report.

4.4.4 Ingestion IMarine Biological Samples

Fish samples are collected quarterly from stations DCM, 7C2 (control), PON, POS, and 7D3 or2F 1. Mussels are collected quarterly from stations DCM, 7C2, and POS. Mussels are collectedannually from station PON. A summary of these samples (required and supplemental) are describedin Table 2.1. A summary of the sample results are provided in Appendix A.

The results for these samples did not detect any plant related radionuclides during sample analysis. 3Marine Aquatic Vegetation

Supplemental marine aquatic kelp sampling is performed quarterly at REMP sample stationsDCM, PON, POS, and 7C2 (control).

Supplemental intertidal algae sampling is performed quarterly at REMP sample stations DCMand 7C2 (control).

Each sample was analyzed for gamma emitting radionuclides. A summary of the sample results areprovided in Appendix A.

The results for these samples did not detect any plant related radionuclides during sample analysis.

Ocean Sediment and Recreational Beach Sampling

Ocean sediment samples are collected annually from stations DCM and 7C2. Strontium-89,StrontiumlYitrium-90, Iron-55, and Nickle-63 were added to the ocean sediment analyses suite. Theresults for these samples did not detect any plant related radionuclides during sample analysis.However, an ocean sediment sample collected on 2/24/06 at station 7C2 detected the presence ofcesium-137 at a concentration of 12.7 pCi/Kg. This cesium is within environmental concentrations Iand can be attributed to worldwide fallout of this isotope from past atmospheric nuclear weaponstesting.

Supplemental recreational beach sand samples were collected from stations Avila Beach (AVA),Montana de Oro (MDO), Pismo Beach (PMO), Cayucos Beach (CYA), and Cambria Beach(CBA). This beach sampling was incorporated into the Offsite Dose Calculation Manual 5

31 3

Page 36: Diablo Canyon, Units 1 and 2 - 2006 Annual Radiological ... · Diablo Canyon Power Plant, Units 1 and 2, submitted in accordance with Technical Specification 5.6.2. The enclosure

(ODCM) as supplemental sampling on a semi-annual frequency. These beach sands werecollected in June and September of 2006. Each sample was analyzed for gamma emittingradionuclides. Strontium-89, Strontium/Yitrium-90, Iron-55, and Nickle-63 were also added tothe sediment analyses suite. Of the recreational beach sand samples collected, only naturallyoccurring isotopes where detected.

Sediment was also collected from the proposed sites of the Independent Spent Fuel StorageInstallation (ISFSI) in June 06 and the Old Steam Generator Storage Facility (OSGSF) inSeptember 06. These samples were collected for preconstruction background analyses.Of these two sediment samples collected, only naturally occurring isotopes where detected.

Vegetation

Samples of broad leaf vegetation are collected monthly (when available) from two indicator stations(7C 1 and 7G1), and one control location (5F2). Samples are collected quarterly from a residencegarden at station 6C 1. The samples are analyzed for gamma emitting radionuclides and for iodine-131 on edible portions.

The results for these samples did not detect any plant related radionuclides during sample analysis.A summary of the sample results are provided in Appendix A.

Milk

There are no milking animals in the vicinity of the plant. In cases where milk sampling is notavailable, the REMP program permits the collection of broad leaf vegetation from three samplelocations in place of milk. Since broadleaf sampling is also noi available in the DCPP environs, theDCPP REMP requires additional air sampling at stations 8S2 and IS1.

Supplemental samples of milk were collected monthly from Cal Poly Farm (station 5F2). Thesamples are analyzed for gamma emitting radionuclides and iodine- 131. Strontium-89 andStrontium/Yitrium-90 analyses were also added to the milk analysis suite in 2006. Milk samples arecollected monthly from station 5F2 regardless of other milking stations being available.

On one occasion, a milk sample (9-5-06) 1-131 LLD was not met due to exceeding the holdingtime for sample analysis. The 9-5-06 sample 1-131 MDC was 1.06 pCi/1 while the LLD was 1.00pCi/l. Milk was re-sampled on 10-3-06 and sent to GEL for analysis. This additional sample metthe 1-131 LLD and satisfied the September monthly timeframe due to the 25% variance allowedin REMP sampling..

One milk sample collected on 5/16/06 indicated the presence of Strontium!Yitrium-90 at aconcentration of 0.453 pCi/L. This result was slightly above the detection limit of 0.451 pCi/I,within environmental background levels, and within the statistical error for analysis.

The results of the milk sampling did not detect any plant related radionuclides. A summary of thesample results are provided in Appendix A.

5.0 GROUND WATER MONITORING

Diablo Canyon is committed to improving management of situations involving inadvertentradiological releases that get into onsite groundwater that is or may be used as a source of drinking water.This commitment reflects the nuclear industry's high standard of public radiation safety and protection ofthe environment. Trust and confidence on the part of local communities, States, the NRC, and the publicis paramount to this commitment.

Studies of the DCPP ISFSI site and a general assessment of sub-regional hydro-geologic conditionsindicates that groundwater (subsurface) flow beneath Diablo Canyon power block site is toward thePacific Ocean and Diablo Creek. It should be noted that Diablo Creek discharges into the Pacific Ocean.

NEI GROUNDWATER PROTECTION INITIATIVE VOLUNTARY REPORTING RESULTS

5.1.1) Reporting Requirement: Document all onsite groundwater sample results and a descriptionof any significant onsite leaks/spills into groundwater for each calendar year in the AREOR.

DCPP Response to # 5.1.1:

Onsite groundwater monitoring points are described and reported in this Annual RadiologicalEnvironmental Operating Report (AREOR) as follows:

WW-02 (Water Well 02), Obs-01 (Observation Well 01), Obs-02 (Observation Well 02), Drywell 115,and WN2 (Diablo Creek Outlet). WW2, OWl, OW2, DY1, and WN2 were used for data reportingrespectively in this report. A summary of the sample results are provided in Appendix A and Appendix B.

Although the NEI Initiative specifies groundwater that is, or could be used as a source of drinking water;DCPP REMP samples all available groundwater regardless of present or future use.

There were no significant onsite leaks/spills into groundwater in 2006.Note: the term "significant" is defined by the NEI Initiative as greater than 100 gallons.

5.2 ADDITIONAL GROUNDWATER SAMPLING OVERVIEW:

Ground water monitoring is reported in accordance with the nuclear industry NEI GroundwaterProtection Initiative. Concentrations of tritium were detected in three monitoring wells beneath the DCPPpower block. These levels of tritium detected were all below the EPA drinking water standard of 20,000pico curies per liter. DCPP is in the process of trending these monitoring wells to obtain data. At theprinting of this report, this tritium is most likely coming from the rain washout of gaseous tritium exitingthe plant vent system. It should be noted that studies of the DCPP site indicate that any groundwater I(subsurface) flow beneath DCPP is not used as a source of drinking water. This groundwater flowdischarges into the Pacific Ocean

The specific ranges of tritium detected in these monitoring well samples for 2006 are as follows:Observation Well 01 ( 464 - 835 pCi/1 ) of eight samples collected for tritium analysisObservation Well 02 ( 2,460 - 2,830 pCi/I ) of seven samples collected for tritium analysisDrywell 115 ( 3,860 - 16,800 pCi/l ) of eight samples collected for tritium analysis

Strontium/Yitrium-90 was detected in one of eight samples at Observation Well 01. This samplewas taken on 2-23-06 and the result was 0.645 pCi/l . The MDC for this sample was 0.414 pCi/l.

Nickel-63 was detected in one of five samples at Observation Well 01. This sample was taken on8-22-06 and the result was 40.9 pCi/1 . The MDC for this sample was 40.5 pCi/I.

StrontiumlYitrium-90 was detected in one of one sample at Observation Well 02. This samplewas taken on 2-23-06 and the result was 1.09 pCi/l. The MDC for this sample was 0.3 89 pCi/1.Observation Well 02 has been dry most of 2006 and therefore unable to provide more water for isotopicanalysis other than tritium sampling.

Cobalt-60 was detected in one of eight samples at Drywell 115. This sample was taken on 8-22-06 and the result was 4.54 pCi/l . The MDC for this sample was 0.76 pCi/l.

All other samples of groundwater aquifers, ponds, creeks, and springs did not indicate thepresence of tritium or any other plant related isotopes (only naturally occurring radionuclides wereobserved). 3

6.0 QUALITY CONTROL

Routine quality control was performed throughout the year to ensure the accuracy of equipment and

procedures used in determining the results. The GEL radiological laboratory also participates in an

external lab Cross-Check Program.

The Nuclear Regulatory Commission (NRC) Branch Technical Position on Radiological Environmental

Monitoring Programs and the DCPP Interdepartmental Administrative Procedure, RP 1 .ID 11,

Environmental Radiological Monitoring Procedure, requires that the GEL laboratory participate in the

Environmental Protection Agency's Environmental Radioactivity Laboratory Inter-comparison Study or

equivalent program. At the end of 1998, the EPA ceased to operate their Inter-comparison Study.

However, GEL has participated in an equivalent program operated by Environmental Resource

Associates of Arvada, Colorado. The GEL participation has included all determinations (sample

medium-radionuclide combination) offered by Analytics which match those as part of the REMIP.

* The results of GEL participation in Environmental Resource Associates Cross CheckProgram for this year are shown in Appendix A, Table A-14.

All of the GEL results of these blind samples were acceptable using the NRC criteria for determining

agreement of confirmatory radiochemical measurements (See Table A-14).

7.0 DCPP ANNUAL LAND USE CENSUS 3Diablo Canyon Power Plant (DCPP) radiation protection personnel conducted a Land Use Census in thevicinity of DCPP for 2006. The land use census is based on Nuclear Regulatory Commission (NRC)

Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear Power Plants" and 10 CFR50 Appendix I section IV. B. 3. DCPP Program Directive CY2, "Radiological Monitoring and ControlsProgram" requires performance of a land use census. 3DCPP IDAP RP 1.ID 11, "Environmental Radiological Monitoring Procedure", requires identification ofthe nearest milk animal, nearest residence, and the nearest broadleaf producing garden greater 3than 50 square meters (500 square feet) in each of the landward meteorological sectors within a distanceof 8 kilometers (5 miles) of the plant. The land use census is conducted at least once per year during thegrowing season (between Feb 15 and Dec 1) for the Diablo Canyon environs. 3The 2006 Land Use Census was conducted via a helicopter over flight on February 21st 2006 along with

personal interviews throughout the year. Thirteen individual landowners or tenants were contacted ibetween July 6 th and November 3 0th, 2006.

No milk animals were identified within the first 8 kilometers (5 miles) of any sector. 3The nearest residence, relative to all sectors, is a small trailer located in the NW sector about 1.93

kilometers (1.2 miles) from the plant. Ranch workers occupy this BLANCHARD residence Iapproximately I month per year during cattle round-ups.

The nearest residence in each sector is summarized in Table 1. 3The land use census identified two household gardens greater than 50 square meters (500 square

feet) that produce broadleaf vegetation. The READ garden is approximately '/4 acre and located in theNNE sector at 7.08 kilometers (4.41 miles). The KOONZE garden is approximately 500 square feet andlocated in the E sector at 7.24 kilometers (4.5 miles). 3

MELLO manages a farm on the coastal plateau, along the site access road, in the ESE sector.The farm starts at approximately 4.8 km and extends to 7.2 km (3 to 4.5 miles) from the plant. This

commercial farm produces no broadleaf vegetation. The farm area is about 100 acres of land with 6 to 10rotational plantings per year (not all 100 acres planted at any one time). Commercial crops consist of

about 25% legumes (sugar peas) and 75% cereal grass (oat hay). Less than 10 farm workers periodically

occupy this area during the growing season.

Much of the area outside the plant site-boundary is used for rotational cattle grazing by five 3separate cattle operations. For purposes of this census, the five cattle ranches are called BLANCHARD,

SINSHEIMER, READ, ANDRE, and MELLO.

BLANCHARD has about 120 cattle outside the plant site-boundary and utilizes the NW, NNW,N, and NNE sectors. About 80 yearling cattle were sold to mass market in 2006. BLANCHARD

37

Page 42: Diablo Canyon, Units 1 and 2 - 2006 Annual Radiological ... · Diablo Canyon Power Plant, Units 1 and 2, submitted in accordance with Technical Specification 5.6.2. The enclosure

slaughtered two cattle in 2006 for personal consumption. Additionally, BLANCHARD managed about200 goats that were used for weed abatement in all landward sectors within the plant site-boundary.During 2006, approximately 100 baby goats were born and then taken to Santa Margarita Californiawhere they are grass fed for 1 year. After one year, the 100 yearling goats are then to be sold to mass-market. BLANCHARD slaughtered one goat in 2006 for personal consumption. BLANCHARD alsomanaged about 100 sheep outside the plant site-boundary in the NW and NNW sectors. These sheep wereallowed to breed and the yearlings were sold to mass market. BLANCHARD slaughtered one sheep in2006 for personal consumption.

SINSHEIMER has about 100 cattle outside the plant site-boundary in the NNE sector. Thesecattle were allowed to breed and about 90 calves were sold to mass market in 2006. SINSHEIMER didnot slaughter any cattle for personal consumption in 2006.

READ has about 150 cattle outside the plant site-boundary in the NNE sector. None of thesecattle were slaughtered for food.

ANDRE has about 80 cattle outside the plant site-boundary in the ENE sector. About 80 calveswere sold to mass market in 2006. ANDRE did not slaughter any cattle in 2006 for personal consumption.

MELLO manages about 1000 cattle outside the plant site-boundary in the E, ESE, and SEsectors. Harris Ranch Beef Corporation owned these cattle and sold all of them to mass market in 2006.MELLO did not slaughter any cattle in 2006 for personal consumption.

Two landowners (JOHE and ANDRE) take wild game for personal consumption outside the plantsite-boundary in the NNE, NE, and ENE sectors. This wild game consists of approximately 2 deer and 4wild pigs per landowner.

There is a California State Park Ranger Office in the NNW sector at 7.483 kilometers (4.65miles) from the plant. Approximately 3 people occupy this office from 1000 to 1500 each day per week.

There is a public campground located in the NNW sector at Montana de Oro State Park at 7.387kilometers (4.59 miles). This campground is near Spooner's Cove.

A total of 14 residences were identified within the 8-kilometer (5-mile) radius of the plant, whichwere confirmed or appear to be occupied during 2006. Two abandoned structures are located in each ofthe NNW and NNE sectors.

Table 1 summarizes the nearest residence location in each meteorological sector.Figure 3 shows the location of the residences and gardens in the vicinity of DCPP.
