SUMMARY

During the year 2009, a Radiological Environmental Monitoring Program (REMP) was conducted for the Diablo Canyon Power Plant (DCPP) to assess the levels of radiation or radioactivity in 0

the environment. More than 1100 samples were collected (including TLDs) over the course of the monitoring period, with approximately 2300 radionuclide or exposure rate analyses being performed.

This report contains results from the operational Radiological Environmental Monitoring 0 Program (REMP) for Diablo Canyon Power Plant (DCPP) compiled for the period January 1, 2009 0 through December 31, 2009. This program is conducted in accordance with DCPP Program Directive CY2, "Radiological Monitoring and Controls Program," and RP 1.ID 11, "Environmental Radiological S Monitoring Procedure."

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

S

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

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

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

S

Fish (FH) Mussels (IM) Sediment (SD)

Diablo Canyon REMP collects environmental samples and ships them to General Engineering S

Labs (GEL) located in Charleston, South Carolina. All REMP lab sample analyses in 2009 were performed by GEL.

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

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

Site related radionuclides were detected in four ocean surface water samples and are discussed in Section 4. The site had no significant impact on surface water radioactivity.

One drinking water sample detected tritium slightly above the minimum detectable concentration

(MDC) capability and is discussed in Section 4. The site had no significant impact on drinking water radioactivity.

Food crops, milk, and meat samples detected only naturally occurring radioactivity; and therefore S had no impact from site operation.

S S

0 0

0 Five fish samples detected Cesium-137 (Cs-137) slightly above the MDC and are discussed in Section 4. This concentration of Cs-137 is routinely seen in fish due to atmospheric nuclear bomb testing in the 1980's. The site had no significant impact on fish radioactivity.

Two aquatic vegetation (algae and kelp) samples detected Cobalt-58 (Co-58) in the discharge cove and are discussed in Section 4. The site had no significant impact on aquatic vegetation radioactivity.

Ground water monitoring data is collected in accordance with the nuclear industry NEI 07-07 Groundwater Protection Initiative (August 2007). Concentrations of tritium were detected in three monitoring wells beneath the DCPP power block (OWl, OW2, and DY1). This tritium is attributed to 0 rain-washout of gaseous tritium exiting the plant vent system (approved discharge path). It should be 0 noted that studies of the DCPP site indicate that any groundwater (subsurface) flow beneath the DCPP 0 power block is not currently used as a source of drinking water. Due to topography and site 0 characteristics, this subsurface flow discharges into the Pacific Ocean which is approximately 100 yards from the power block.

Beginning in February 2009, the DCPP Unit One (U-i) Steam Generators were replaced and the 0

old U-1 Steam Generators (4 total) were stored onsite within the Old Steam Generator Storage Facility (OSGSF) mausoleum. Beginning in October 2009, the DCPP Unit Two (U-2) Reactor (Rx) Head was replaced and the old U-2 Rx Head was stored onsite within the OSGSF mausoleum. As of 12-31-09, the OSGSF contains eight old Steam Generators and one old Rx Head. This OSGSF did not cause any changes to the ambient direct radiation levels in the DCPP environs during 2009.

The OSGSF building sumps were inspected quarterly by the REMP. Rainwater was found in the U-2 Old Steam Generator vault # 30 sump during the fourth quarter inspection due to rain events in October. This rainwater had tritium concentrations consistent with rainwater washout concentrations. As a conservative measure, the rainwater from the sump was removed and processed via an approved radwaste 0 discharge pathway. 0 Beginning in June 2009, DCPP began loading of the Independent Spent Fuel Storage Installation 0 (ISFSI) and is discussed in Section 4. The ISFSI had no significant impact to the inner ring REMP TLD 0 station readings. 0 The results of the 2009 REMP showed no unusual findings from site 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.

1.0 INTRODUCTION

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

0 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 by DCPP REMP personnel in one of two local fish markets for

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

Thermoluminescent Dosimeter (TLD) Lab.

0DCPP sends replicate samples of milk (5F2), drinking water (DW1), outfall water (OUT), Diablo

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

Department of Public Health (CDPH) Radiological Health Branch as part of a State cross check program.

Other pathways monitored independently by the CDPH are direct radiation and air sampling.

0 2.0 PROGRAM DESIGN 0

The Radiological Environmental Monitoring Program (REMP) for the Diablo Canyon Power Plant 0 (DCPP) was designed with the following specific objectives in mind. These objectives will continue to be in force, to varying degrees, throughout facility operation.

0 To provide an early indication of the appearance or accumulation of any radioactive material in the environment caused by facility operation. Preoperational data is also used in this comparison.

0 To provide assurance to regulatory agencies and the public that the station's environmental impact is known and within anticipated limits.

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

0 0

The environmental media selected were based on the critical dose pathways of the radionuclides from 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 beach sand, groundwater, meat, 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 Radiological Assessment Branch Technical Position on Radiological Environmental Monitoring, Revision 1, November 1979 O0 The detailed sampling requirements of the REMP are given in Table 2.1 of this report. Summaries of REMP sampling for the period are shown in Appendix A of this report. Direct dose (environmental TLDs) results are shown in Appendix B of this report. The REMP sample isotopic results (including 2 sigma total propagated error) are shown in Appendix C of this report. Any deviations from the REMP sampling schedule requirements are documented in section 4.0 of this report.

2.1 MONITORING ZONES 0 The REMP is designed to allow comparison of levels of radioactivity in samples from the areas possibly influenced by DCPP to levels found in areas not influenced by the facility operations. Areas with the potential to be influenced by facility operations are called "indicator" stations. Areas with sufficient distance from the plant that are not likely to be influenced by facility operations are called the "control" stations. The distinction between the two zones is based on relative direction from the plant and distance. Analysis of survey data from the two zones aids in determining if there is a significant difference between the two areas. It can also help in differentiating between radioactive releases and seasonal variations in the natural environmental background.

2.3 DESCRIPTION

S OF REMP MONITORING 2.3.1 Direct Radiation Direct ambient radiation was measured at 31 stations in the vicinity of DCPP using

Panasonic UD814 TLD badges. The TLD badges had valid element correction

factors (ECF), were calibrated using a NIST-traceable cesium-137 source, were annealed prior to placement, and were sealed in watertight packaging. These badges were replaced on a quarterly basis.

0

Direct ambient radiation was measured at 8 stations in the vicinity of the ISFSI using Panasonic UD814 TLD badges. The TLD badges had valid element

correction factors (ECF), were calibrated using a NIST-traceable cesium-137

source, were annealed prior to placement, and were sealed in watertight packaging.

These badges were replaced on a quarterly basis.

The field TLD badge packets were prepared and processed by DCPP personnel and the DCPP TLD Lab. Control badges were carried with the field badges to measure any dose received during transit. The location, date, and time of exchange were

recorded on a log sheet which accompanied the field badges. The net exposure was

, reported over a standard 90 day quarter.

2.3.2 Airborne Radioactivity

Air particulate and radioiodine sampling were performed weekly at six indicator

stations: MT1, 0S2, IS1, 7D1, 8S1 and 8S2. Air particulate and radioiodine

sampling was performed weekly at one control station: 5F1.

Constant flow air samplers were used to draw air through paper filters to collect 0 air particulates and through triethylenediamine (TEDA) impregnated charcoal cartridges to collect radioiodine. The air samplers were set at a flow rate of 1.5 standard cubic feet per minute. The air samplers were located approximately one meter above the ground. The sample volumes were determined by F&J Corporation model DF-1 flowmeters (corrected to standard temperature and pressure, STP) which are installed downstream.of the sample head. At the end of the sampling period (weekly), the filter and cartridge were collected. All necessary data regarding the air volume readings, flowrate, sampler time on and off, date of collection, and sampler location were recorded and submitted to GEL along with the samples for analysis.

0 Approximately 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months after sampling (to allow for radon and thoron daughter decay), the filter papers collected from the field were placed on individual planchets and counted for gross beta activity in a low background, thin window gas proportional counter. Gamma isotopic analysis was then performed on quarterly composites of the filters (by location) to determine the activity concentration of gamma emitting isotopes.

0 The TEDA impregnated charcoal cartridges were counted for each weekly sampling period at each location for gamma isotopic analyses to determine the radioiodine concentration.

2.3.3 Waterborne 0 Water samples (drinking water, surface water, monitor wells, and groundwater) were collected at the frequencies shown in Table 2.1 0

Ocean surface water samples were collected at Diablo Cove (station DCM),

Rattlesnake Canyon (station 7C2), and at the plant Outfall (station OUT).

Drinking water samples were collected from Diablo Creek Weir (station 5S2),

Diablo Creek Outlet (station WN2), Blanchard Spring (station 1A2), and from the DCPP drinking water system (station DW1). Drinking water was also collected from a control station located in San Luis Obispo at the Offsite Emergency Lab (station OEL).

Supplemental groundwater samples were collected from Water Well 02 (WW2) and DCSF96-1 (8S3).

Supplemental onsite monitoring well samples were collected from Observation Well 01 (OWl), Observation Well 02 (OW2), and a french drain system labeled Drywell 115 (DYI). These wells are located in close proximity to the facility power block structures and within the protected area.

0 After collection, the samples were securely sealed and labeled with sample type, location, date, time of collection, and the person performing the collection and sent to GEL for analysis.

0 2.3.4 Marine Biological, Beach Sand, and Ocean Sediment The REMP requires sampling of rockfish (family Sebastes), perch (family

Embiotocidae), mussels(family Mytilus), and ocean sediment from indicator

station DCM and control station 7C2. All other marine samples collected are considered supplemental. These supplemental marine samples included the following: intertidal algae, intertidal mussels, kelp, and market fish. The intertidal

samples were collected by DCPP personnel during low tidal conditions. Kelp was

collected quarterly by DCPP personnel from the offshore kelp bed in the vicinity of the plant. Quarterly samples of fish and an annual sample of ocean sediments were

collected from the plant environs by contracted divers (TENERA Environmental)..

0 The Tenera divers fillet the fish and leave a small portion of skin for identification.

Beach sand was collected by DCPP personnel between the high and low tide boundaries at nearby recreational beaches. Fish caught locally by commercial

fishermen were purchased from two local fish markets (Avila Beach Pier-7D3 and

Morro Bay-2F 1).

All samples were subject to unavailability due to seasonal fluctuations or unfavorable sampling conditions. The above samples were sealed in plastic bags immediately upon collection. Mussels are sent to GEL in-shell where GEL

personnel remove the meat & internal organs for analysis. Only edible portions

of the fish were analyzed (fish fillets). The samples were labeled with sample type, location, date, time of collection, and individual performing the collection.

The samples were then frozen (to prevent spoilage odor) before they were sent to

GEL for analysis.

2.3.5 Food Crops The REMP requires broadleaf food vegetation to be collected in the nearest off-

site locations of the highest calculated annual average ground level D/Q

(dispersion parameter) within 5 miles. There is no broadleaf food vegetation

available that satisfies this requirement. Because these food products are unavailable, the DCPP REMP conducts additional air sampling in the SE (station 8S2) and NNW (station 1S1) sectors. Additional representative samples of food

crops in season were collected monthly from supplemental stations: Cal Poly Farm (5F2), Kawaoka Farm in Arroyo Grande (7G1), Mello Farm (7C1) along the site access road, and a quarterly household garden (6C 1).

0 The monthly samples were collected by DCPP personnel and sealed immediately in plastic bags. The quarterly household garden sample (6C1) is provided to

DCPP personnel by the land occupant (due to access difficulty and privacy). The

samples were labeled with sample type, location, collection date, collection time, and the individual performing the collection. The samples were normally frozen

before they were sent to GEL for analysis (to prevent spoilage odor).

0 2.3.6 Milk There are no animals within the vicinity of the plant that are utilized for milk consumption by humans. However, supplemental samples of cow milk were

collected monthly from Cal Poly Farm (5F2) which is approximately 13 miles

from DCPP. Two 1-gallon plastic containers of milk were collected each sampling period by DCPP personnel. Forty grams of sodium bio-sulfite

preservative were added to each gallon of milk sample. The containers were S

2.3.7 Meat A rancher routinely grazes cattle, goats, and sheep within three miles of the site boundary. These livestock meats were offered at local farmer's markets and private distribution. This meat commodity began at the end of 2007. REMP personnel obtained meat samples of each species directly from the land owner.

Gamma spec and strontium analyses were performed on the meat.

0 Property owners could hunt deer and wild pig (in season) within 5 miles of the site boundary. The REMP attempted to get meat samples from these property owners when available. Gamma spec and strontium analyses were performed on the meat (when provided). No deer or pig meat were provided in 2009.

The meat was initially packaged by the livestock owners and turned over to REMP personnel. The packages were then separated by species and placed in large zip-lock bags. Each bag was labeled with sample type, location, collection date, collection time, and the individual performing the collection. The samples were then frozen and sent to GEL for analysis.

5. If food products are unavailable, additional air sampling as specified in Table 2.1, Parts 2 & 3 will be done in the SE S (Station 8S2) and NNW (station 1S l) sectors.

0 6. The Branch Technical Position (Nov 79) states, "Any location from which milk can'no longer be obtained may be dropped from the surveillance program after notifying the NRC in writing that they are no longer obtainable at that location".

Although milk sampling performed at 5F2 is outside the 5-mile radius and is supplemental to the REMP, this notification should take place if 5F2 milk sampling ceases.

In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background will include the typical contributions 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 routine, conditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Environmental Radiological Operating Report.

Typical values of E, V, Y and t should be used in the calculation. It should be recognized that the LLD is defined as a priori (before the fact) limit representing the capability of a measurement system and not as a posteriori (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 during the monitoring period. The results, shown in Appendix A, are presented in a format similar to that prescribed in the NRC's Radiological Assessment Branch Technical Position on Environmental Monitoring.

The results are ordered by sample media type and then by radionuclide.

Each table is nuclide specific, and the total number of analyses for that radionuclide during the monitoring 0period, 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 matrix or pathway sampled during the period. The second column lists the nuclides analyzed and number of samples

performed. The third column provides the required Lower Limit of Detection (LLD) for radionuclides that

have detection capability requirements as specified in Table 2.3 of this report. The sixth and seventh columns contain the mean and average results for locations. The eighth column contains the number for reportable occurrences for the location pathway. Occasionally, the required LLD is not met. An example 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 specified radionuclide/ media type, the range, and the number of samples that were considered to have detectable activity of all the samples counted.

The mean value consists of all concentrations, including negative values and values considered "rnot detectable".

0 The lowest and highest concentration values.

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 that radionuclide, contained detectable radioactivity.

0 A sample is considered to yield a "detectable measurement" when the concentration exceeds three times its 0 associated standard deviation.

The radionuclides reported in this section represent those that:

1) had an LLD requirement in Table 2.3 of this report, or a Reporting Level listed in Table 2.4

2) were of specific interest for any other reason The radionuclides routinely analyzed and reported for a gamma spectroscopy analysis are: Ac-228, Ag-

ll0m, Be-7, K-40, Ce-144, Co-57, Co-58, Co-60, Cr-51, 1-131, Cs-134, Cs-137, Ba-140, La-140, Fe-59,

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 format

described above. Actual quarterly TLD results are listed in Appendix B.

4.0 ANALYSIS OF ENVIRONMENTAL RESULTS 4.1 REMP Sampling Variance / Deviations The DCPP Radiological Environmental Monitoring Program allows for deviations in the REMP sampling schedule "if samples are unobtainable due to hazardous conditions, seasonal unavailability, or malfunction of sampling equipment." Such deviations do not compromise the program's effectiveness and are normally anticipated for any radiological environmental monitoring program.

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

DIRECT RADIATION The environmental TLD holder for 0S2 was found damaged on 12-30-09 (broken and laying on ground) due to cattle grazing. It was determined this condition existed for approximately one day and this station was repaired immediately. There were no abnormal affects to the station readout.

0 AIRBORNE RADIOACTIVITY The mean percent availability for all on-site and off-site air samplers was 99.7 percent. This means, on average, all air samplers were up and running 99.7 percent of the time. The remaining 0.3 percent can be attributed to equipment problems, filter exchange, and calibration processes.

Approximately 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of air sampler lost run time occurred at stations 5F1 and 7D1 from 4-8-09 to 0 4-15-09 due to electrical storms which caused loss of power at these locations.

Approximately 33.7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months of air sampler lost run time occurred at station MT1 from 4-29-09 to 5-6-09 due to power source maintenance.

Approximately 106.25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months of air sampler lost run time occurred at station 8SS1 from 9-23-09 to 9-30-09 due to equipment malfunction.

0 Approximately 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months of air sampler lost run time occurred at station MT1 from 11-11-09 to 11-18-09 due to equipment malfunction.

0 MARINE SAMPLES All marine samples were collected as scheduled (including allowable variation).

0 One set of DCM & POS kelp samples for third quarter 2009 were sent to GEL instead of to the State of California for split sampling. Additional kelp sampling was conducted within the same month (July) and sent to the State of California to meet the third quarter kelp sample requirement.

0 The California Department of Fish and Game has issued regulations prohibiting the collection of abalone along the central and southern coast of California. PG&E considers is unlikely that collection of abalone will be allowed in the DCPP environs in the near future. The REMP has therefore ceased routine abalone sampling. Note that the sampling of abalone was previously performed and was supplemental to the REMP.

0 TERRESTRIAL SAMPLES All terrestrial samples were collected as scheduled (including allowable variation) with the exception of

July, August, September, and October vegetation samples from REMP station 7C 1. No vegetation was available at 7C1 during those months of 2009. It should be noted that this vegetation sample is

supplemental to the REMP.

0 3C1 vegetation samples were not provided by the landowner in 2009.

OCEAN SURFACE WATER, DRINKING WATER, AND GROUNDWATER SAMPLES All water samples were collected as scheduled (including allowable variation).

REPLICATE SAMPLES Replicate sampling is conducted within the REMP for program strength and correlation.

Replicate samples were taken from OWl Monitor Well (1-22-09 & 3-19-09),5 F2 Vegetation (3-18-09),

CYA Cayucos beach sand (5-26-09), 7C2 Seawater (5-27-09), DCM Seawater (5-27-09), OUT Seawater

(5-27-09), and 5F2 Milk (9-8-09). The results of the analyses were within expected correlation.

4.2 COMPARISON OFACHIEVED LLDS WITH REQUIREMENTS For each analysis having an LLD requirement, criteria for. the calculated "a priori" (before the fact) LLD were met during the sampling and analysis process. Meeting these process criteria satisfies the "a priori" LLD requirements. The "a posteriori" (after the fact) Minimum Detectable Concentration (MDC) for that analysis was also compared with the required "a priori" (before

the fact) LLD.

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

All samples analyzed met the specific "a-priori" LLD requirements in 2009.

0

4.3 COMPARISON OF RESULTS AGAINST REMP REPORTING LEVELS 0* Notification is required whenever a Reporting Level in Table 2.4 of this document is exceeded.

Reporting Levels are the environmental concentrations that relate to the ALARA design dose objectives of 10 CFR 50, Appendix I. It should be noted that environmental concentrations are averaged over calendar quarters for the purposes of this comparison, and that Reporting Levels apply only to measured levels of radioactivity due to effluents.

No REMP Reporting Levels were exceeded during this monitoring period.

4.4 DATA ANALYSIS BY MEDIA TYPE-The REMP data for each media type is discussed below. A sample is considered to yield a "detectable measurement" when the concentration exceeds three times its associated standard deviation.

4.4.1 Direct Radiation Direct radiation is continuously measured at 31 locations surrounding DCPP using thermoluminescent 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 DCPP TLD Lab. The results are trended with preoperational and historical operating values for adverse trends. No adverse trends were noted in 2009 as indicated by the graph that follows.

LO 0

Direct radiation is also continuously measured at 8 locations surrounding the Independent Spent Fuel Storage Installation (ISFSI) using thermoluminescent dosimeters (TLDs). These 8 locations are located directly adjacent to the ISFSI protected area, with 2 stations on each of the four sides of the ISFSI pad. It should be noted that these stations and the ISFSI are well within the site boundary. These dosimeters are collected every calendar quarter for readout at the DCPP TLD Lab. The first spent fuel canister was loaded onto the ISFSI pad in June 2009. The small increase in radiation levels at the ISFSI pad prior to spent fuel canister load was due to storage of Radioactive Material (RAM) at the ISFSI pad prior to an outage. The Radioactive Material was outage equipment stored in seatrains at the ISFSI pad. These seatrains of RAM were removed prior to the first load of spent fuel canisters. No adverse trends were noted at the DCPP inner ring stations due to ISFSI for 2009 as indicated by the graphs that follow. It should be noted that the DCPP inner ring TLD results actually tracked downward in correlation with normal Environmental TLD flucuations.

0 4.4.2 Airborne Air particulate and radioiodine samples were collected weekly from six indicator stations (MT 1, 0S2, 1S1, 7D1, 8S1, and 8S2) in the DCPP environs and one control station (5F1). A total of 364 air particulate filters and 364 iodine cartridges were collected and analyzed. The data collected for the air-sampling program is summarized in Appendix A.

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

0 Gamma isotopic analyses were performed on quarterly composites of the air particulate filters from each station. All samples collected during the monitoring period contained only naturally occurring radioactivity.

A total of 364 iodine cartridges were analyzed for iodine-13 1. No Iodine-13 1 was detected in any 0 of the iodine cartridges.

4.4.3 Drinking Water, Ocean Surface Water, and Groundwater Drinking Water Drinking water samples were collected from stations DW1, 5S2, WN2, 1A2, and OEL (control location). The samples were analyzed for gamma emitters, gross beta, tritium, Total Strontium, Iron-55, and Nickle-63. Iodine-131 was analyzed by ion exchange procedures.

O0 One sample from 5S2 indicated tritium (279 pCi/L) slightly above the MDC (255 pCi/L).

Of all other samples collected during the monitoring period, no plant related radionuclides were detected in any of the samples.

Ocean Surface Water Ocean surface water samples were collected monthly from stations OUT, DCM, and at 7C2 5 (control location). The samples were analyzed for gamma emitters, gross beta, tritium, Total Strontium, Iron-55, and Nickle-63.

Ni-63 was detected at REMP station DCM seawater (surface water) on 1-21-09. The result was 30.4 pCi/L and the MDC was 30.3 pCi/L.

Tritium was detected at REMP station OUT seawater (surface water) on 5-27-09. This result can be attributed to a plant discharge via the approved discharge path (outfall).

Tritium was detected at REMP station DCM seawater (surface water) on 11-5-09. This result can be attributed to a plant discharge via the approved discharge path (outfall).

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

0 Groundwater

As part of the nuclear industry NEI 07-07 Groundwater Protection Initiative, DCPP began sampling various water sources in'2006. These sources included onsite monitoring wells, an 0aquifer well, a creek, and a water spring.

0 Two groundwater aquifer wells are available within the plant site boundary; Water Well 01 and Water Well 02. These wells are located about 115' above and to the east of the power block.

Water Well 01 is abandoned and the well pump is inoperable. Water Well 02 was sampled and only naturally occurring isotopes were detected.

Three shallow (approximately 37 to 73 feet deep) subsurface monitoring wells are located within the plant protected area and in close proximity to the containment structures, spent fuel pools, and auxiliary building (plant power block). These monitoring wells are labeled Observation Well 01 (OW 1), Observation Well 02 (OW2), and Drywell 115 (DY1).

Due to rainwater washout of gaseous tritium exiting the plant vent system (approved discharge path), these monitoring wells contained low levels of tritium throughout 2009.

All three of these monitoring wells were below the maximum concentration level (MCL) established by the U.S. Environmental Protection Agency (EPA) for tritium (20,000 picocuries per liter). Further reporting of these monitoring wells is provided in Section 5.2 of this report.

4.4.5 Food Crops (Vegetation) 0 Samples of broad leaf vegetation were collected monthly (when available) from two indicator stations (7C1 and 7G1), and one control location (5F2). Samples were collected quarterly from a residence garden at station 6C 1. The samples were analyzed for gamma emitting radionuclides and for Iodine- 131 on edible portions.

No broad leaf vegetation samples were provided by the landowner for 3C1 in 2009.

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.

4.4.6 Milk 0

There are no milking animals in the vicinity of the plant. In cases where milk sampling is not available, the REMP program permits the collection of broad leaf vegetation from three sample locations in place of milk. Since broadleaf sampling is also not available in the DCPP environs, the DCPP REMP requires additional air sampling at stations 8S2 and 1iS 0.

Supplemental samples of milk were collected monthly from Cal Poly Farm (station 5F2). The samples were analyzed for gamma emitting radionuclides, Iodine- 131, and Total Strontium. Milk samples were collected monthly from station 5F2 regardless of the availability of milk stations within 5 miles of the plant.

0 5.0 GROUND WATER MONITORING Diablo Canyon is committed to improving management of situations involving inadvertent radiological 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 of the environment. Trust and confidence on the part of local communities, States, the NRC, and the public is paramount to this commitment.

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

5.2 ADDITIONAL GROUNDWATER SAMPLING OVERVIEW:

Ground water monitoring is reported in accordance with the nuclear industry NEI 07-07 0Groundwater Protection Initiative. Concentrations of tritium were detected in three monitoring wells

beneath the DCPP power block. This tritium is coming from the rain-washout of gaseous tritium exiting the plant vent system via an approved discharge route. It should be noted that hydro geological studies of

the DCPP site indicate that any groundwater (subsurface) flow beneath DCPP would flow toward the

Pacific Ocean.

0The specific ranges of tritium detected in these monitoring well samples for 2009 are as follows:

Observation Well 01 ( 1,050 - 2,440 pCi/L ) of 9 samples collected for tritium analysis.

Observation Well 02 ( 1,070 - 1,850 pCi/L ) of 9 samples collected for tritium analysis.

Drywell 115 ( 4,210 - 10,000 pCi/L ) of 9 samples collected for tritium analysis.

0 All other samples of groundwater at WW2, 8S3, and WN2 did not indicate the presence of tritium or any other plant related isotopes (only naturally occurring radionuclides were observed).

S 6.0 OLD STEAM GENERATOR STORAGE FACILITY MONITORING O In accordance with the DCPP Offsite Dose Calculation Manual (ODCM), the Old Steam Generator Storage Facility (OSGSF) sumps were inspected quarterly. If water was found in the sump of a vault containing plant equipment, the expectation was to sample that sump water and dispose of the water per plant protocols.

Beginning in February 2009, the DCPP Unit One (U-i) Steam Generators were replaced and the O old U-I Steam Generators (4 total) were stored onsite within the Old Steam Generator Storage Facility (OSGSF) mausoleum.

Beginning in October 2009, the DCPPUnit Two (U-2) Reactor (Rx) Head was replaced and the O old U-2 Rx Head was stored onsite within the OSGSF mausoleum.

As of 12-31-09, the OSGSF contains eight old Steam Generators and one old Rx Head. This OSGSF did not cause any changes to the ambient direct radiation levels in the DCPP environs during O 2009. O The OSGSF building sumps were inspected quarterly by the REMP. Rainwater was found in the U-2 Old Steam Generator vault # 30 sump during the fourth quarter inspection due to rain events in October. This rainwater had tritium concentrations consistent with rainwater washout concentrations. As a 0 conservative measure, the rainwater from the sump was removed and processed via an approved radwaste discharge pathway.

2009 INTERLABORATORY COMPARISON PROGRAM REPORT 0In accordance with US Nuclear Regulatory Commission requirements, GEL Laboratories, LLC (GEL)

participates in an Interlaboratory Comparison Programs (ICP) that satisfies the requirements of both

Regulatory Guide 4.15, Revision 1, "Quality Assurance for Radiological Monitoring Programs (Normal

Operations) - Effluent Streams and the Environment", February 1979 and -Regulatory Guide 4.15, Revision 2, "Quality Assurance for Radiological Monitoring Programs (Inception through Normal

Operations to License Termination) - Effluent Streams and the Environment", July, 2007. Both guides

indicate the ICP is to be conducted with the Environmental Protection Agency (EPA) Environmental

Radioactivity Laboratory Intercomparison Studies (Cross-check) Program or an equivalent program, and the ICP should include all sample medium/radionuclide combinations that are offered by the EPA and included in the REMP.

0

Intercomparison samples were obtained from Eckert & Zeigler Analytics of Atlanta, Environmental Resource Associates of Arvada, Colorado and the Mixed Analyte Performance Evaluation Program (MAPEP). Each provider has a documented Quality Assurance (QA) program and the capability to

prepare Quality Control (QC) materials traceable to the National Institute of Standards and Technology.

The ICP is a third party blind testing program which provides a means to ensure independent checks

are performed on the accuracy and precision of the measurements of radioactive materials in environmental sample matrices. The providers supply the crosscheck samples to GEL. Upon receipt,

the laboratory performs the analyses in a normal manner. The results are then reported to the provider

for evaluation.

The samples offered by ICP providers and included in GEL's analyses are gamma isotopic analyses of an air filter, milk, water, soil and vegetation, Sr-89/90 in Milk and water and 1-131 in cartridges. The

accuracy of each result reported to Analytics, Inc is measured by the ratio of GEL's result to the known

value. Accuracy~for all other results is based on statistically derived acceptance ranges calculated by

the providers. An investigation is undertaken whenever the ratio or reported result fell outside of the acceptance range.

A summary of GEL's results is provided in the tables below for the required sample matrix types and

isotopic distribution. Delineated in the table are: the Sample Number or Study ID; Analysis quarter and year; sample media; specific radionuclide; its unit; its result; the known values supplied by the providers; GEL's ratio to the known value or acceptance criteria provided by the provider; evaluation

criteria.

0 GEL analyzed 31 samples for 151 parameters in 2009. All results except one met the acceptance 0 criteria and are discussed below.

The root cause of the Sr-90 failures was determined to be a batch quality control issue. The

carrier yield for the second separation was greater than 100%. The elevated yield caused the Sr-90 result to be biased low. Even though the yield fell within its acceptance range, if 0 problem solved 0

8.0 DCPP 2009 ANNUAL LAND USE CENSUS S Diablo Canyon Power Plant (DCPP) Radiological Environmental Monitoring Program (REMP) personnel conducted a land use census in the vicinity of DCPP for 2009. The land use census is based on Nuclear Regulatory Commission (NRC) Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear Power Plants" and 10 CFR 50 Appendix I section IV. B. 3.

DCPP Program Directive CY2, "Radiological Monitoring and Controls Program" requires performance of a land use census.

DCPP IDAP RP1.ID1 1, "Environmental Radiological Monitoring Procedure", requires identification of the nearest milk animal, nearest residence, and the nearest broadleaf producing garden

.greater than 50 square meters (500 square feet) in each of the landward meteorological sectors within a distance of 8 kilometers (5 miles) of the plant. The land use census is conducted at least once per year during the growing season (between Feb 15 and Dec 1) for the Diablo Canyon environs.

The 2009 Land Use Census was conducted via a helicopter over-flight and landowner telephone interviews. The helicopter over-flight was conducted on March 2 7th, 2009. The telephone interviews were conducted October 2 1S' through November 3 rd, 2009. Thirteen individual landowners or tenants were contacted.

Milk:

No milk animals were identified within the first 8 kilometers (5 miles) of any sector.

Residences:

The 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 approximately 1 month per year during cattle round-ups.

A total of 17 residences were identified within the 8-kilometer (5-mile) radius of the plant, which were confirmed or appear to be occupied during 2009. Two abandoned structures are located in each of the NNW and NNE sectors.

A new structure (with miscellaneous equipment) was located during the over-flight at GPS coordinates N35* 13.203 , W120* 46.414. This structure is abandoned (not used).

The nearest residence in each sector is summarized in Table 1.

0 Gardens:

The land use census identified two household gardens greater than 50 square meters (500 square feet) that produce broadleaf vegetation. The READ garden is approximately 1/4 acre and located in the NNE sector at 7.08 kilometers (4.41 miles). The KOONZE garden is approximately 500 square feet and located in the E sector at 7.24 kilometers (4.5 miles).

S 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 S commercial farm produces no broadleaf vegetation. The farm area is about 100 acres of land with 6 to 10 rotational plantings per year (not all 100 acres planted at any one time). Commercial crops consist of about 100% cereal grass (oat hay). Less than 10 farm workers periodically occupy this area during the growing season.

0 Additional Land Use:

Much of the area outside the plant site-boundary is used for rotational cattle grazing by five separate 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 2009. BLANCHARD slaughtered two cattle in 2009 for personal consumption.

Additionally, BLANCHARD managed about 200 goats that were used for weed abatement in all landward sectors within the plant site-boundary. During 2009, approximately 100 baby goats were born and then taken to Santa Margarita California where 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 2009 for personal consumption.

BLANCHARD also managed about 100 sheep outside the plant site-boundary in the NW and NNW sectors. These sheep were allowed to breed and the yearlings were sold to mass market.

BLANCHARD slaughtered one sheep in 2009 for personal consumption.

BLANCHARD meats were sampled by REMP personnel.

0 SINSHEIMER has about 100 cattle outside the plant site-boundary in the NNE sector. These cattle were allowed to breed and about 90 calves were sold to mass market in 2009. SINSHEIMER did S not slaughter any cattle for personal consumption in 2009.

R A

READ has about 150 cattle outside the plant site-boundary in the NNE sector.

ANDRE has about 80 cattle outside the plant site-boundary in the ENE sector. About 80 calves

were sold to mass market in 2009. ANDRE did not slaughter any cattle in 2009 for personal consumption.

0 MELLO manages about 1000 cattle outside the plant site-boundary in the E, ESE, and SE sectors. Harris Ranch Beef Corporation owned these cattle and sold all of them to mass market in 2009.

MELLO did not slaughter any cattle in 2009 for personal consumption.

S

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

There is a California State Park Ranger Office in the NNW sector at 7.483 kilometers (4.65

miles) from the plant. Approximately 3 people occupy this office from 1000 to 1500 each day per week.

There is a public campground (Islay Creek Campground) located in the NNW sector at Montana

de Oro State Park at 7.387 kilometers (4.59 miles). This campground is near Spooner's Cove.

Approximately 712,645 people visited Montana de Oro State Park via day use permit.

Approximately 22,073 people spent the night at Islay Creek Campground.

There is public access to hiking trails at the north and south ends of the plant property. S S

The Point Buchon Trail is located at the north end of PG&E property and has about 20,000 visitors annually. It traverses about 3.5 miles of coastline from Coon Creek to Crowbar Canyon. The trail is open for day hikes Thursday thru Monday from approximately 0800-1600. Two to three people from California Land Management occupy the trail head booth during operating hours. This trail was opened to the public on July 13, 2007.

The Pecho Coast Trail is located at the south end of PG&E property and has about 2,500 visitors annually. The trail is approximately 3.7 miles long and leads to the Point San Luis Lighthouse near Avila Beach. Access is controlled (by permission only) and conducted by docents. This trail is just slightly outside the 5 mile radius of the plant. Pecho Coast Trail hikes are only available on Wednesdays (about 20 people) and Saturdays (about 40 people). 30-40 Lighthouse keepers occupy the Lighthouse grounds on Tuesdays, Thursdays, and Saturdays from 0800-1600. The Lighthouse property is owned by the Harbor District.
