EXECUTIVE

SUMMARY

During the year 2008, 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 500 samples were collected (including TLDs) over the course of the monitoring period, with over 1000 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, 2008 through December 31, 2008. This program is conducted in accordance with DCPP Prograrn Directive CY2, "Radiological Monitoring and Controls Program," and RP .ID1 1, "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)

Diablo Canyon REMP collects environmental samples and ships them to General Engineering Labs (GEL) located in Charleston, South Carolina. All REMP lab sample analyses in 2008 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 Diablo Cove surface water samples and are discussed in Section 4. The site had no significant impact on surface water.

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

One fish sample from station PON detected Cesium-137 slightly above the MDC. All other marine samples contained only naturally occurring radionuclides.

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 2

monitoring wells beneath the DCPP power block (OWl, OW2, and DYI). In February of 2008, one of the monitoring wells (DYl) was cross contaminated with roof drain rain-washout of gaseous tritium. From Feb 2008 until Nov 2008, the tritium concentration in that monitoring, well exceeded the EPA drinking water standard of 20,000 picocuries per liter. These three wells are now tracking tritium values between 700 to 7,000 picocuries per liter. This tritium is attributed to rain-washout of gaseous tritium exiting the plant vent system (approved discharge path). It should be noted that studies of the DCPP site indicate that any groundwater(subsurface) flow beneath the DCPP power block is not used as a source of drinking water. Due to topography and site characteristics, this subsurface flow discharges into the Pacific Ocean.

Since DCPP site operation began in 1985, a local university (Cal Poly of San Luis Obispo) had conducted independent radioanalytical environmental sampling at their campus radioanalytical lab. Those sample results were shared semi-annually with California Stdite Dept of Public Health (Rad Health Branch). Beginning in January of 2008, the Cal Poly radioanalytical lab ceased environmental sampling.

This activity previously performed by Cal Poly has no affect on the DCPP REMP.

Beginning in February 2008, the DCPP Unit Two (U-2) steam generators were replaced and the old U-2 steam generators (4 total) were stored onsite within the Old Steam Generator Storage Facility (OSGSF) mausoleum. This OSGSF did not cause any changes to the ambient direct radiation levels in.the DCPP environs during 2008. The OSGSF building sumps were inspected quarterly by the REMP with no water observed during each inspection and therefore no OSGSF effluent monitoring to report.

On May 21, 2008 the site primary meteorological tower (MET) was damaged by crane operations. This primary MET tower had to be replaced during the third quarter of 2008. Due to this event, there is a higher frequency of west-northwest wind direction in 2008 when compared to previous periods (see MET data in 2008 DCPP Annual Radioactive Effluents Release Report). This is due to substitution of data from the backup MET tower 10-meter level for the summer months when the primary tower was out-of-service.

The results of the 2008 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

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

Unit I 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.

DCPP 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.

This report summarizes the quarterly findings of the Radiological Environmental Monitoring Program (REMP) conducted by the Diablo Canyon Power Plant. The remainder of this report is organized as follows:

Section 2: Provides a description of the overall REMP design. Included is a summary of the requirements for REMP sampling and tables listing routine sampling and TLD monitoring locations with distances from the plant. Tables listing Lower Limit of Detection requirements and Reporting Levels (NRC notification if levels are exceeded) also included.

Section 3: Consists of the summarized data as required by the Radiological Environmental Monitoring Program. The summaries are provided similar to that specifiedby the NRC Branch Technical Position on Environmental Monitoring.

Section 4: Provides a summary of the results for the samples collected. The performance of the program in meeting the requirements is discussed, and the data acquired during the monitoring period is analyzed. Also included is environmental TLD preoperational data trending.

Section 5: Provides a summary of groundwater monitoring in accordance with the nuclear industry NEI 07-07 Groundwater Protection Initiative (August 2007).

2.0 PROGRAM DESIGN 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 radioactive material in the environment caused by facility operation. Preoperational data is also used in this comparison.

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

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.

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 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 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 The REMP is designed to allow comparison of levels of radioactivity in samples from the area 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 betwee6 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.

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: MTl, 0S2, I11, 7D1, 8S1 and 8S2. Air particulate and radioiodine sampling was performed weekly at one control station:5F 1.

Constant flow air samplers were used to draw air through paper filters to collect 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 8

Corporation model DF-I 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.

Approximately 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> 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.

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 Water samples (drinking water, surface water, and groundwater) were collected at the frequencies shown inTable 2.1 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 DWI). 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).

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.

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.

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 9

the plant. Quarterly samples of fish and an annual sample of ocean sediment were collected from the plant environs by contracted divers (TENERA Environmental)..

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 and Morro Bay).

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 IS 1) sectors. Additional representative samples of food crops in season were collected monthly from supplemental stations: Cal Poly Farm (5F2), Kawaoka Farm in Arroyo Grande (7G]), Mello Farm (7C1) along the site access road, and a quarterly household garden (6C 1).

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).

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 sealed and shaken thoroughly to distribute the preservative. The containers were labeled with sample type, location, collection date, collection time, and the individual performing the collection. The samples were then express shipped to GEL for analysis.

10

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.

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 2008.

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.

Table Notations

1. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to circumstances such as hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons.

If specimens are unobtainable due to sampling equipment malfunction, effort shall be made to complete corrective action prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report. It is recognized that, at times, it may not be possible or practicable to continue to obtain samples of the media of choice at the most desired location or time. In these instances, suitable specific alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the Radiological Environmental Monitoring Program, and submitted in the next Annual Radioactive Effluent Release Report, including a revised figure(s) and table for the ERMP reflecting the new location(s) with supporting information identifying the cause of the unavailability of samples for that pathway and justifying the section of the new location(s) for obtaining samples.

2. For the purposes of this table, a thermoluminescent dosimeter (TLD) is considered to be one phosphor. There are normally three calcium sulfate phosphors in an environmental TLD BADGE. Film badges shall not be used as dosimeters for measuring direct radiation.

3: Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24.hours or more after sampling to allow for radon and thoron daughter decay. If gross beta activity in air particulate samples is greater than 10 times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

4. Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from the facility.
5. If food products are unavailable, additional air sampling as specified in Table 2.1, Parts 2 & 3 will be don e in the SE (Station 8S2) and NNW (station 1S1) sectors.
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.

TABLE 2.3 (Continued)

Table Notations For 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-curie Y = the fractional radiochemical yield (when applicable)

= the radioactive decay constant for the particular radionuclide t = 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 actual observed variance of the background counting rate or of the counting rate of theblank samples (as appropriate) rather than on an unverified theoretically predicted variance. 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 period, 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 "not detectable".

" 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.

A sample is considered to yield a "detectable measurement" when the concentration exceeds three times its 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-I 10m, 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 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.

On May 21, 2008 the site primary meteorological tower (MET) was damaged by crane operations. This primary MET tower had to be replaced during the third quarter of 2008. Due to this event, there was a higher frequency of west-northwest wind direction in 2008 when compared to previous periods (see MET data in the 2008 DCPP Annual Radioactive Effluents Release Report). This was due to substitution of data from the backup MET tower 10-meter level for the summer months when the primary tower was out-of-service.

The DCPPREMP 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.

AIRBORNE RADIOACTIVITY The mean percent availability for all on-site and off-site air samplers was 99.2 percent. This means, on average, all air samplers were up and running 99.2 percent of the time. The remaining 0.8 percent can be attributed~to equipment problems, filter exchange, and calibration processes.

Approximately i 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> of air sampler lost run time occurred at station 7DI from 1-4-08 to 1-9-08 due to electrical storms which caused loss of power at this location.

Approximately 130 hours0.0015 days <br />0.0361 hours <br />2.149471e-4 weeks <br />4.9465e-5 months <br /> of air sampler lost run time occurred at station 5F1 from 1-30-08 to 2-6-08 due to equipment malfunction.

During the week of 2-27-08 to 3-5-08, the charcoal cartridges for stations 8S1 and MTI were not labeled by REMP personnel due to human error. The lab counted both charcoal cartridges and the two results were arbitrarily assigned to the two station codes (at the direction of the DCPP REMP Engineer). Both of the station filter Iodine- 131 results were below minimum detectable concentration (MDC).

Approximately 74 hours8.564815e-4 days <br />0.0206 hours <br />1.223545e-4 weeks <br />2.8157e-5 months <br /> of air sampler lost run time occurred at station 7D1 from 6-11-08 to 6-18-08 due to equipment malfunction.

Approximately 144 hours0.00167 days <br />0.04 hours <br />2.380952e-4 weeks <br />5.4792e-5 months <br /> of air sampler lost run time occurred at station 7DI from 7-17-08 to 7-23-08 due to equipment malfunction.

The REMP investigated the above air sampler equipment malfunction issues. It was found that some station power supply voltages vary which cause the air sampler electronics to shut off. Power conditioners were installed at all air sampler locations and the equipment malfunctions have ceased.

26

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

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.

TERRESTRIAL SAMPLES All terrestrial samples were collected as scheduled (including allowable variation) with the exception of third and fourth quarter vegetation samples from REMP station 7C1. No vegetation was available at 7C1 during the third and fourth quarters of 2008. It should be noted that this vegetation sample is supplemental to the REMP.

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 7G1 Vegetation (3-6-08), 2F1 Market Fish (4-7-08), CBA Cambria beach sand (8-4-08), and WW2 Groundwater. (12-2-08). The results of the analyses were within expected correlation.

27

4.2 COMPARISON OF ACHIEVED 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.

Iodine-131 LLDs were not initially met for 3 drinking water samples taken in April 2008. The reason for this problem was due to detector efficiencies of a new detector at the lab. Additional samples of these locations were taken on April 2 3rd and the Iodine-131 LLDs were met for that month.

All other samples analyzed met the specific "a-priori" LLD requirements in 2008.

4.3 COMPARISON OF RESULTS AGAINST REMP REPORTING LEVELS 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 2008 as indicated by the graph that follows.

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.

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- 131. No Iodine-131 was detected in any of the iodine cartridges.

29

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.

Of the 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 (control location). The samples were analyzed for gamma emitters, gross beta, tritium, Total Strontium, lron-55, and Nickle-63.

Iron-55 was detected at REMP station DCM seawater (surface water) on 1-30-08. 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 2-19-08. 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 8-20-08. 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 9-16-08. 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.

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

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 aquifer well, a creek, and a water spring.

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 (OWl), Observation Well 02 (OW2), and Drywell 115 (DYI).

Due to rainwater washout of gaseous tritium exiting the plant vent system (approved discharge path), these monitoring wells contained low levels of tritium throughout 2008.

30

Routine tritium sampling from REMP station DYI (Drywell 115) indicated tritium results in excess of 20,000 pCi/L starting on 2-18-08. Investigation of this event revealed a cross-contamination issue from building roof drains into the well. The building roof drains contain rain-washout tritium concentrations. Sampling was conducted during a February rain storm which allowed rainwater from the drain to enter the well. The well tritium values tracked consistent with rain events and sampling during the rest of 2008. At the end of 2008, the DY I was pumped down and the water processed via the plant radwaste system. The DYI tritium concentration at the end of 2008 was less than 7,000 pCi/L and continues to track less than this value.

One sample from Drywell 115 (DY1) collected on 11-20-08 detected the presence of Co-60 at 24.9 pCi per liter with an error of 3.32 pCi per liter. The MDC for this sample was 1.77 pCi per liter. This cobalt could be attributed to the large amount of construction activity in the immediate area for Steam Generator Replacement Outages. Subsequent sampling has not identified Co-60.

At the end of 2008, 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..

4.4.4 Ingestion Marine Biological Samples Fish samples were collected quarterly from stations DCM, 7C2 (control), PON, POS, and a local market (7D3 or 2F1). Mussels were collected quarterly from stations DCM, 7C2, and POS. Mussels were collected annually from station PON. A summary of these samples (required and supplemental) is described in Table 2.1. A summary of the sample results is provided in App A.

Cesium- 137 was detected at REMP station 7D3 (market fish) on 7-28-08. The sample was statistically proven to be a false positive.

Cesium-137 was detected at REMP station PON (perch fish) on.9-12-08. The sample was statistically proven to be a false positive.

Cesium-137 was detected at REMP station 7C2 (rockfish) on 9-12-08. The sample was statistically proven to be a false positive.

All other samples did not detect any plant related radionuclides during sample analysis.

Marine Aquatic Vegetation Supplemental marine aquatic kelp sampling was performed quarterly at REMP sample stations DCM, PON, POS, and 7C2 (control).

Supplemental intertidal algae sampling was performed quarterly at REMP sample stations DCM and 7C2 (control).

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

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

31

Ocean Sediment and Recreational Beach Sampling Ocean sediment samples were collected annually from stations DCM and 7C2. Gamma Spec, Total Strontium, Iron-55, and Nickle-63 were analyzed.

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). Each sample was analyzed for gamma emitting radionuclides. Total Strontium, Iron-55, and Nickle-63.

Only naturally occurring isotopes where detected in the ocean sediment and recreational beach sand samples collected for 2008.

4.4.5 Food Crops (Vegetation)

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 6C1. The samples were 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.

4.4.6 Milk 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 1S1.

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.

The results of the milk sampling did not detect any plant related radionuclides.

A summary 6f the sample results are provided in Appendix A.

4.4.7 Meat Products Meat products are collected quarterly (when available and provided) from landowners.

Samples of livestock meat were collected from the Blanchard Ranch in 2008. These samples were Blanchard cow meat (BCM), Blanchard sheep meat (BSM), and Blanchard goat meat (BGM).

Sample results are listed in Appendix C. Only naturally occurring Potassium-40 was detected in these samples, no plant related radionuclides were detected.

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 toward the Pacific Ocean or Diablo Creek. It should be noted that Diablo Creek also discharges into the Pacific Ocean.

5.1 NEI 07-07 GROUNDWATER PROTECTION INITIATIVE VOLUNTARY REPORTING 5.1.1 NEI 07-07 Objective 2.4, Annual Reporting:

Document all on-site ground water sample results and a description of any significant on-site leaks/spills into ground water for each calendar year in the AREOR.

DCPP Response to NEI 07-07 Objective 2.4 Onsite groundwater monitoring points are described and reported in this Annual Radiological Environmental Operating Report (AREOR) as follows:

Observation Well 01 (OWl), Observation Well 02 (OW2), Drywell 115 (DY1), Water Well 02 (WW2), and Diablo Creek Outlet (WN2) were used for data reporting. A summary of the. sample results are provided in Appendix A and Appendix C.

DCPP REMP sampled all available groundwater regardless of present or future use. The ground water beneath the DCPP protected area is not and will not be used as a source of drinking water.

There were no significant onsite leaks/spills into groundwater in 2008.

Note: the term "significant" is defined by the NEI Initiative as an item or incident that is of interest to the public or stakeholders. It does not imply or refer to regulatory terminology noris it intended to indicate that the leak or spill has public health and safety or environmental protection consequences. This term also has a volume component of greater than 100 gallons.

33

5.1.2 NEI 07-07 Objective 2.2, Voluntary Communication:

Make informal notification as soon as practicable to appropriate State/Local officials, with follow-up notification to the NRC, as appropriate, regarding significant on-site leaks/spills into groundwater and on-site or off-site water sample results exceeding the criteria in the REMP ODCM reporting/notification levels.

DCPP Response to NEI 07-07 Objective 2.2 Routine tritium sampling from REMP station DYI (Drywell 115) indicated tritium results in excess of 20,000 pCi/L starting on 2-18-08. Investigation of this event revealed a cross-contamination issue from building roof drains into the well. The building roof drains contain high rain-washout tritium concentrations. High levels of DY1 cross contamination occurred when sampling was conducted during a February rain storm which allowed rainwater from the roof drain to enter the well. The DYI tritium concentrations increased from 8,000 pCi/L to 41,000 pCi/L. 1The DYI maximum tritium concentration observed was 44,500 pCi/L and the DY1 tritium values tracked consistent with rain events and sampling during the rest of 2008. At the end of 2008, the DYI was pumped down and the water processed via the plant radwaste system. The DYI tritium concentration at the end of 2008 was approximately 7,000 pCi/L and continues to track less than this value.

This event was tracked in the site corrective action process.

An informal communication was made by the Radiation Protection Manager (RPM) to a local government official. No further actions were requested by the government official.

This information was also presented to the resident NRC inspector at DCPP with no further actions requested.

Additionally, the RPM presented this material at a public NRC meeting with no comment from the public or NRC officials.

5.1.3 NEI Objective 2.3, Thirty -Day Reports:

Submit a 30-day report to the NRC for any water sample result for on-site ground water that is or may be used as a source of drinking water that exceeds any of the criteria in the licensee's existing REMP as described in the ODCM for 30-day reporting of off-site water sample results. Copies of the written 30-day reports for both on-site and off-site water samples shall also be provided to the appropriate State/Local officials.

DCPP Response to NEI 07-07 Objective 2.3 There were no reports generated in 2008 for groundwater results exceeding reporting/notification levels.

5.2 ADDITIONAL GROUNDWATER SAMPLING OVERVIEW:

Ground water monitoring is reported in accordance with the nuclear industry NEI 07-07 Groundwater Protection Initiative. Concentrations of tritium were detected in three monitoring wells beneath the DCPP power block. This tritium is most likely coming from the rain-washout of gaseous tritium exiting the plant vent system via an approved discharge route. 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 The specific ranges of tritium detected in these monitoring well samples for 2008 are as follows:

Observation Well 01 ( 667 - 1,290 pCi/L ) of 21 samples collected for tritium analysis.

Observation Well 02 ( 977 - 1,500 pCi/I ) of 21 samples collected for tritium analysis.

Drywell 115 ( 6,980 - 44,5010 pCi/l ) 6f 44 samples collected for tritium analysis.

One sample from Drywell 115 (DYI) collected on 11-20-08 detected the presence of Co-60 at 24.9 pCi per liter with an error of 3.32 pCi per liter. The MDC for this sample was 1.77 pCi per liter. This cobalt could be attributed to the large amount of construction activity in the immediate area for Steam Generator Replacement Outages. Subsequent sampling has not identified Co-60.

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

6.0 OLD STEAM GENERATOR STORAGE FACILITY MONITORING 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.

The Unit Two Steam Generators (4 total) were placed in the OSGSF Vault 30 at the end of February 2008. Vault 30 was sealed and locked. The OSGSF solely contained the U-2 old Steam Generators for the remainder of 2008.

The sump for Vault 30 was inspected quarterly during all four quarters in 2008 and no water was found in the sump.

7.0 QUALITY CONTROL 1NTERLABORATORY COMPARISON PROGRAM In accordance with US Nuclear Regulatory Commission requirements, GEL Laboratories, LLC participates in an Interlaboratory Comparison Programs (ICP) that satisfies the requirements of Regulatory Guide 4.15, Revision 1, "Quality Assurance for Radiological Monitoring Programs (Normal Operations) - Effluent Streams and the Environment", February 1979. The guide indicates 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.

Samples were obtained from Analytics, Inc. of Atlanta, Georgia, 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 Laboratory, LLC. 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, and vegetation, Sr-89/90 in Milk and 1-131 in air. 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 for each of the media/analysis combinations are: the specific radionuclide; analytical dates; the known values with their uncertainties supplied by the providers; results with their standard deviations; the ratio and the acceptance range.

36

GEL analyzed 15 samples for 77 parameters in 2008. All results except twelve met the acceptance criteria and are discussed below.

  • The first quarter Sr-89 in milk result fell below the acceptance criteria. All data were reviewed with no errors apparent. A batch duplicate was also analyzed with this sample and it's result fell within the acceptance criteria. All other quality control criteria were met. No further investigation was performed.
  • The root cause of the Sr-90 failure was determined to be method inaccuracies when using a small sample volume. The Sr-90 data over the past 2.5 years was evaluated using average relative bias and relative precision statistics as outlined in ANSI N 13.30. The average relative bias over this period is 0.0230 which is an excellent average relative bias. The relative precision was within the recommended 0.40 range at 0.2325. This indicated the method was in control. The normal procedure utilized 500 - 800 mL of sample for analysis resulting in a lower defection limit and a lower uncertainty when compared to the analysis of the cross check samples normally utilizing 200 mL of sample due to limited sample volume

" The root cause of the Gamma Emitter (Ba-133, Cs-134, Cs-137, Co-60, Zn-65) failures were attributed to an incorrect dilution. The samples were received as concentrates and must be diluted prior to preparation. Per the instructions, the samples should have been diluted to a final volume of 2 liters but instead were diluted to 4 liters. All instructions are now scanned by the Quality Assurance Officer and emailed to the laboratory Group Leader when the samples are logged. The instructions are also stored in a location. accessible to all laboratory personnel.

The Cs-137 result fell just above the acceptance criteria. All data- were reviewed with no apparent errors. A batch duplicate was also analyzed with this sample and its results fell within the acceptance criteria. All other quality control criteria were also met. A remedial sample was performed and the results fell within the acceptance range.

  • The root cause of the Americium-241 and Cesium-134 failures is thought to be matrix interference and the potential for volatilization. Two containers (1O0g and lOg) of this sample were received and logged for all parameters., All results were reported from the 100g. The Quality Assurance Officer (QAO) was later informed by the group leader that the gamma results should have been reported from the f Og container due to matrix interference and the, potential for volatilization of some of the compounds.
  • The Nickel-63 failure was attributed an unusually low gravimetric yield.

The cause of the Fe-55 failure was determined to be interference from Co-60. The Standard Operating Procedure (SOP) has been modified to include additional rinses and Cobalt carrier to help eliminate Cobalt as an interferent. The sample was also re-analyzed after the SOP modification and acceptable results were obtained.

Routine lab quality control was also performed throughout the year to ensure the accuracy of equipment and procedures used in determining the results. These internal lab practices included blind spikes, QC samples, replicates, blanks, and other lab "good practice" protocols.

8.0 DCPP 2008 ANNUAL LAND USE CENSUS Diablo Canyon Power Plant (DCPP) Radiological Environmental Monitoring Program (REMP) personnel conducted a Land Use Census in the vicinity of DCPP for 2008. 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 2008 Land Use Census was conducted via a helicopter over-flight.and landowner telephone interviews. The helicopter over-flight was conducted on September 3 ,rd, 2008. The telephone interviews were conducted November 12th through November 2 0 th, 2008. 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 I month per year during cattle round-ups.

A total of 16 residences were identified within the 8-kilometer (5-mile) radius of the plant, which were confirmed or appear to be occupied during 2008. Two abandoned structures are located in each of the NNW and NNE sectors.

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

Gardens:

The land use census identified two household gardens greiter than 50 square meters (500 square feet) that produce broadleaf vegetation. The READ garden is approximately 11/4 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).

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 10 rotational plantings per year (not all 100 acres planted at any one time). Commercial crops consist of about 10% squash and 90% cereal grass (oat hay),. Less than 10 farm workers periodically occupy this area during the growing season.

46

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 2008. BLANCHARD slaughtered two cattle in 2008 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 2008, 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 2008 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 2008 for personal consumption.

BLANCHARD meats were sampled by REMP personnel.

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 2008. SINSHEIMER did not slaughter any cattle for personal consumption in 2008.

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 2008. ANDRE did not slaughter any cattle in 2008 for personal consumption.

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 2008.

MELLO did not slaughter any cattle in 2008 for personal consumption.

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 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.

Groundwater. Impacts:

On November 17th, 2008 Diablo Canyon ceased make-up water usage from Diablo Creek (REMP station 5S2). The lower dam was breached due to Coastal Commission requirements for the Old Steam Generator Storage Facility building permit. Prior to November 17 th, DCPP used approximately 80 gpm of creekwater as a makeup source to the 100K tank which provided water to the plant makeup reservoir and the 30K tank which provided water to the plant fire suppression system.

To replace the creek makeup water source, DCPP refurbished Water Well 02 (REMP station WW2). Prior to November 2008, this WW2 provided aquifer water at approximately 10 gpm to DCPP makeup systems. After November 2008, WW2 is expected to supply approximately 100 gpm to the IOOK and 30K tanks.

WW2 was refurbished to be a production well 350 ft deep with a 10 inch casing. Test results verified the well could sustain more than 150 gpm even during drought conditions. Drawdown test data show the WW2 pump ground elevation at 333 ft above sea level with the maximum drawdown of the well during normal operation at 133 ft above sea level. Therefore, this aquifer resides at an elevation of approximately 133 ft above sea level. With the DCPP power block located at approximately 115 ft to 50 ft above sea level, there is little chance 'f plant power block communication with the WW2 aquifer.

In support of this WW2 refurbishment, two additional exploration wells were drilled and permitted for testing only. One well is Water Well 04 which is 506 ft deep and is located southwest of WW2. Another test Well is Water Well 05 which is 409 ft deep and is located northeast of WW2 in the paved area behind the document storage building (near the maintenance garage). Both wells are over 1/2V2 mile to the east of the plant power block. Water Well 04 and Water Well 05 have been capped and are no longer available.

An old 13K water tank is located directly east of the 500 kV switchyard and near Water Well 01 (WW1). This old 13K water tank historically received water from the pre-Nov08 WW2. During these makeup water construction changes, a new 13K water tank was constructed near the actual physical location of WW2. The old 13K was abandoned. The makeup water flow from WW2 is now to this new 13K tank (acting as a surge tank) which then feeds into the lOOK tank.

Aquifer testing was conducted by Environmental and Natural Resource Management Consultants (ENTRIX) and the final report submitted to DCPP (dated 8-22-08).

Table I summarizes the nearest residence location in each meteorological sector.

Figure 3 shows the location of the residences and gardens in the vicinity of DCPP.
