SUMMARY

During the year 2012, 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 1400 samples were collected (including TLDs) over the course of the 2012 monitoring period, with approximately 2100 radionuclide or exposure rate analyses performed.

This report contains results from the operational Radiological Environmental Monitoring Program for Diablo Canyon Power Plant compiled for the period January 1,2012 through December 31,2012. This program was conducted in accordance with DCPP Program Directive CY2, "Radiological Monitoring and Controls Program," and RP1.IDll, "Environmental Radiological Monitoring Procedure." This report was submitted per DCPP License Technical Specification 5.6.2.

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

Air Particulate (AP) Air Cartridges (AC) for iodide monitoring, Direct Radiation (TLD's) Milk (MK) Meat (MT) Vegetation (VG)

Drinking Water (DW) Ground Water (GW) Surface Water (SW) Aquatic Vegetation (A V)

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

Diablo Canyon REMP collected environmental samples and shipped them to General Engineering Labs (GEL) located in Charleston, South Carolina. All 2012 REMP environmental lab isotopic sample analyses were performed by GEL.

The ambient direct radiation levels in the DCPP offsite environs did not change and were within the preoperational range. Beginning in June 2009, DCPP began loading of the onsite Independent Spent Fuel Storage Installation (ISFSI). The ISFSI had no significant impact on the REMP TLD station readings in the vicinity of the site boundary and beyond. The ambient direct radiation levels within the DCPP plant site boundary near the ISFSI were elevated due to dry cask spent fuel storage. An evaluation of direct radiation measurements and member of public occupancy times surrounding the ISFSI indicated all federal criteria for member of public dose limits were conservatively met.

On March 11 th , 2011 the Tohoku-Oki earthquake (magnitude 9.0 Mw) and tsunami struck the east coast of Japan. The tsunami associated with this event caused nuclear accidents at the Dai-Ichi Nuclear Power Station in Fukushima Prefecture, Japan. Isotopic releases occurred in Japan and were carried by the jet stream to the west coast of the United States during March 2011. Throughout 2012, the DCPP REMP continued to detect cesium (Cs-137) within milk, vegetation, monitoring wells, fish, and meat due to deposition ofCs-137 from that event and the approximate 30 year half-life ofCs-137. Additional discussion on Fukushima related Cs-137 is found within Section 4.5 of this report.

Groundwater isotopic monitoring was conducted in accordance with the nuclear industry NEI 07-07 Groundwater Protection Initiative (GPI). Concentrations of tritium were detected in five monitoring wells (stations OWl, OW2, DYl, GWl, and 8S3) near the power block. This tritium was evaluated and attributed to rain-washout of gaseous tritium exiting the plant vent system (via an approved isotopic-effluents discharge path). No groundwater tritium has been attributed to DCPP system leaks or spills.

Concentrations of cesium (Cs-137) were also detected in two shallow monitoring wells (DYI and 8S3).

This cesium was evaluated and attributed to rain-washout of Fukushima fallout isotopes during March 2011 rain events along the Central Coast of California (ref. 2011 DCPP AREOR). During these 2011 rain events, Fukushima related Cs-137 was deposited into the Central Coast environs in concentrations of2.4 to 25.4 pCilLiter. This Fukushima Cs-I37 was detected locally in 2012 environmental samples due to the approximate 30 year half-life of Cs-13 7. It should also be noted that studies of the DCPP site groundwater gradient indicated that any groundwater (subsurface) flow beneath the DCPP power block was not used as a source of drinking water. Due to topography and site characteristics, this groundwater gradient flow discharged into the Pacific Ocean which is approximately 100 yards from the power block.

An Old Steam Generator Storage Facility (OSGSF) long term storage mausoleum was constructed within the DCPP site boundary in 2007 for storage of eight retired DCPP steam generators and two retired DCPP reactor heads. This equipment was placed into this OSGSF on the following dates:

March 2008 (outage 2RI4), four DCPP Unit Two (U-2) Steam Generators

February 2009 (outage IRI5), four DCPP Unit One (U-I) Steam Generators

November 2009 (outage 2RI5), one DCPP Unit Two (U-2) Reactor (Rx) Head

October 2010 (outage lRI6), one DCPP Unit One (U-l) Rx Head This OSGSF did not cause any changes to the ambient direct radiation levels within the DCPP environs during 2012.

The OSGSF sumps were inspected quarterly by REMP personnel. Construction repairs made in 2011 to the OSGSF have prevented rainwater from entering the OSGSF throughout 2012. These OSGSF sumps have re~ained empty and dry during 2012.

The results of the 2012 REMP showed no unusual environmental isotopic findings from DCPP site operations.

These results were compared to DCPP preoperational isotopic data and showed no unusual trends.

Diablo Canyon site operations had no significant environmental radiological impact on airborne, surface water, drinking water, marine life, aquatic vegetation, terrestrial vegetation, sediment, milk, or meat radioactivity.

1.0 INTRODUCTION

Diablo Canyon Power Plant (DCPP) consists of two Westinghouse pressurized water reactors. Unit 1 began commercial operation in 1985, and Unit 2 began commercial operation in 1986.

Radiological Environmental Monitoring Program (REMP) samples were collected by DCPP REMP personnel and sent to General Engineering Labs (GEL) in Charleston, South Carolina for isotopic analysis.

Fish (except market fish) and ocean sediment samples were collected by contract divers of Tenera Environmental and given to DCPP REMP personnel for shipment to GEL. Market fish samples were 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 analyzed by the DCPP Thermo-luminescent Dosimeter (TLD) Lab.

DCPP REMP sent replicate samples of stations 7Gl vegetation (quarterly), 5F2 milk (monthly), 5S2 drinking water (monthly), DWI drinking water (monthly), OUT seawater (monthly), DCM kelp (quarterly), DCM perch (quarterly), DCM rockfish (quarterly), and DCM ocean sediment (annually) to the California Department of Public Health - Radiologic Health Branch (CDPH-RHB) Laboratory as part of a California State cross-check program. These cross-check samples were independently analyzed by the CDPH-RHB. Other pathways monitored independently by the CDPH-RHB were quarterly direct radiation TLD stations (MTl, lAl, lCl, 4D1, 5F3, 5S1, 7Dl, 7Cl, 7Fl, and 8S2) and weekly air sampling particulate and I-131 (at stations 5F3 and 7D 1). The general public should contact the CDPH-RHB for those results.

This report summarizes the findings of the Radiological Environmental Monitoring Program (REMP) conducted by 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 exceeded) are also included.

Section 3: Consists of the summarized data as required by the Radiological Environmental Monitoring Program. The summaries are provided similar to that specified by 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.

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 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.

Any deviations from the REMP sampling schedule / requirements are documented in section 4.0 of this report.

Data summary tables 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 individual isotopic results are shown in Appendix C of this report. Detected concentrations of nuclear power plant related isotopes (not naturally occurring isotopes including gross beta) have been highlighted with yellow for quick identification by the reader.

2.1 MONITORING ZONES The REMP was 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 distance and relative direction from the plant. Analysis of survey data from the two zones aided in determination of site environmental influence. Analysis from the two zones helped in differentiation between radioactive releases and seasonal variations in the natural environmental background. It also helped with differentiation of Fukushima related isotopes found within the environment since March 2011.

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 caesium-137 source, were annealed prior to placement, and were sealed in watertight packaging. Three badges were placed at each station each quarter. These badges were replaced on a quarterly basis.

Direct ambient radiation was measured at 8 stations in the vicinity of the Independent Spent Fuel Storage Installation (lSFSI) using Panasonic UD814TLD badges. The TLD badges had valid element correction factors (ECF), were calibrated using a NIST-traceable caesium-137 source, were annealed prior to placement, and were sealed in watertight packaging. Three badges were placed at each station each quarter. 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.

DCPP Environmental TLD standard quarter results are measurements of all environmental gamma radiation sources (cosmic, terrestrial, radon, etc) at each station during the deployment period. Transient and lab storage background dose contributions were subtracted prior to reporting.

2.3.2 Airborne Radioactivity Air particulate and radioiodine sampling were performed weekly at six indicator stations: MTl, OS2, lSI, 7Dl, 8S1 and 8S2. Air particulate and radioiodine sampling was performed weekly at one control station: 5F1.

Constant flow air samplers (F&J model DF-l) were used to draw air through paper filters to collect air particulates and through triethylenediamine (TEDA) impregnated charcoal cartridges to collect radioiodine. From January to August, the air samplers were set at a flow rate of 1.5 standard cubic feet per minute. In August, REMP air samplers were converted to read out in units of cubic meters per hour in order to correlate with cubic meter reporting criteria. From August to December, the air samplers were set to a flow rate of2.55 cubic meters per hour (which is equivalent to 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-l flowmeters (corrected to standard temperature and pressure, STP) which were installed downstream of the sample head. At the end of the weekly sampling period, the filter and cartridge were

collected. All necessary data regarding the air volume readings, flowrate, sampler time on / off, date of collection, and sampler location were recorded and submitted to GEL along with the samples for isotopic analysis.

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 particulate 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.

Quarterly gamma spectroscopy isotopic analysis was performed on composites of the filters (by station) to determine the activity concentration of gamma emitting isotopes. The quarterly composite is reported at the midpoint of the quarter monitored.

Each station weekly TEDA impregnated charcoal cartridge was counted for gamma spectroscopy isotopic analysis to determine the radioiodine concentration.

2.3.3 Waterborne Water samples (drinking water, surface water, monitor wells, and groundwater) were collected at the frequencies shown in Table 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 lA2), and from the DCPP drinking water system (station DWl). 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-l (8S3).

Supplemental on-site monitoring well samples were collected from Observation Well 01 (OWl), Observation Well 02 (OW2), and a french drain system labeled Drywell 115 (DYl). These shallow wells were located in close proximity to the

facility power block structures and within the protected area.

Two new on-site monitoring wells were installed in December 2011 and isotopic sampling began at the beginning of2012. These two new onsite wells are downgradientofthe power block and located along the western side of the power block. These two new monitoring wells are l<tbeled Groundwater 1 (GW1) and Groundwater 2 (GW2).

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

2.3.4 Marine Biological, Beach Sand, and Ocean Sediment The REMP required 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 were 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). 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-2F1).

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 were sent to GEL in-shell where GEL

personnel removed the meat & internal organs for analysis. Only edible portions of the fish were analyzed (fish fillets). The samples were labeled with sample type, station ID, date, time of collection, and the individual who performed 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 required 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 S miles. There was no broadleaf food vegetation available that satisfied this requirement. Because these food products were unavailable, the DCPP REMP conducted additional air sampling in the SE (station 8S2) and NNW (station lSI) sectors.

Additional representative samples of food crops in season were collected monthly from supplemental stations: Cal Poly Farm (SF2), Kawaoka Farm in Arroyo Grande (7G 1), Mello Farm (7Cl) along the site access road, and quarterly household gardens (3C 1 and 6C 1).

The monthly samples (including 3Cl) were collected by DCPP personnel and sealed immediately in plastic bags. The quarterly household garden sample (6Cl) was provided to DCPP personnel by the land occupant (due to property access difficulty and privacy).

The samples were labeled with sample type, station ID, collection date, collection time, and the individual who performed collection. The samples were normally frozen before they were sent to GEL for analysis (to prevent spoilage odor).

2.3.6 Milk There were no animals within the vicinity of the plant that were utilized for milk consumption by humans. However, supplemental samples of cow milk were collected monthly from Cal Poly Farm (SF2) which was approximately 13 miles from DCPP.

Two I-gallon plastic containers of milk were collected each sampling period by DCPP personnel. Forty grams of sodium bisulfite 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, station ID, collection date, collection time, and the individual who performed collection.

The samples were then express shipped to GEL for analysis.

2.3.7 Meat A rancher routinely grazed cattle, goats, and sheep within three miles of the site boundary (free range, grass fed). These livestock meats were offered at local farmer's markets and private distribution. This meat distribution commodity began at the end of 2007. Because it was possible for this vendor to provide an individual's sole-source of annual meat consumption, it was included in the REMP. REMP personnel obtained commercially packaged meat samples of each species directly from the land owner. Gamma spec and strontium analyses were performed on the meat.

Additional meat sampling was conducted of Hearst Ranch meat which is located approximately 37 miles north of the DCPP site. This Hearst Ranch meat is free range, grass fed beef. This REMP station code was HCM and provided a control location far from the site to help differentiate Fukushima related isotopes. REMP personnel purchased this Hearst Ranch meat directly from local public grocery stores.

Property owners could hunt deer and wild pig (in season) within 5 miles of the site boundary. The REMP obtained one deer meat sample from these property owners (voluntary participation). Gamma spec and strontium analyses were performed on the deer meat.

The meat was initially packaged by the livestock owners or commercial processes. The meat was purchased at local grocery stores or turned over to REMP personnel. The unopened packages were then separated by species and placed into large over-pack zip-lock bags. Each bag was labeled with sample type, station ID, collection date, collection time, and the individual who performed the collection. The samples were then frozen and sent to GEL.

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 ofthe 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 thermo luminescent 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 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months 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 broadleaf vegetation food products are unavailable, additional air sampling as specified in Table 2.1, Parts 2 & 3 will be done in the NNW (station lSI) and SE (Station 8S2) 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.

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)

'A 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 the blank 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 ofE, 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.

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 a-priori Lower Limit of Detection (LLD) for radionuclides that have detection capability requirements as specified in Table 2.3 of this report. The fourth, fifth, and sixth columns contain the mean and average results for locations. The seventh 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 4.2 of this report.

The a-posteriori Minimum Detectable Concentration (MDC) listed for each analysis in Appendix C was used as the detection evaluation point for each sample collected in the calendar year. The MDC was calculated by the laboratory with each analysis (a-posteriori) and incorporates conditions observed at the laboratory during the analysis. This MDC value mathematically represents the lowest concentration of activity that can be detected by the laboratory with a 95% confidence level.

The MDC is also understood as the concentration where there is only a 5% probability of falsely reporting a positive detection in a true blank sample. Note that the a-posteriori MDC equation used by the environmental lab is the same as the a-priori Lower Limit of Detection (LLD) equation specified in NUREG 1301.

For this report, a sample is considered to yield a "detectable measurement" when the "result" concentration exceeds the associated a-posteriori MDC value for that analysis.

Additionally, the tables of Appendix A provide the mean of all sample results analyzed for the specified radionuclidel 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 the average of detectable concentrations.

The lowest and highest detected concentration values were listed

The number of detectable measurements and the total number of measurements were listed. For example, (4120) would indicate that 4 of the 20 samples collected, for that sample type and that radionuclide, contained detectable radioactivity.

The radionuclides reported in this section represent those that:

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

were of specific interest for any other reason The radionuclides routinely analyzed and reported for a gamma spectroscopy analysis are: Ac-228, Ag-llOm, Be-7, K-40, Ce-144, Co-57, Co-58, Co-60, Cr-5l, 1-131, Cs-134, Cs-137, Ba-140, La-140, Fe-59, Mn-54, Nb-95, Ru-l03, Rh-l06, 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 1 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.

4.1.1 DIRECT RADIATION There were no abnormal effects to the 2012 station environmental TLD results.

ISFSI projects completed the 2012 spent fuel loading campaign at ISFSI on 3-17-12.

4.1.2 AIRBORNE RADIOACTIVITY The mean percent availability for all on-site and off-site air samplers was 100 percent. This means, on average, all air samplers were up and running 100 percent of the time. Less than 0.1 percent could be attributed to equipment problems, filter exchange, and calibration processes.

Actual annual percent availability for each station was as follows:

OS2= 100%

lSI = 100 %

SF1 = 99.9 %

7D1 = 99.9 %

8S1 = 100 %

8S2= 100%

MT1 = 100%

No air sampling lost run-time events occurred in 2012.

4.1.3 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.

4.1.4 TERRESTRIAL SAMPLES All terrestrial samples were collected as scheduled (including allowable variation) with the following exceptions:

A vegetation sample taken on 11115/12 from Station 3Cl was lost in shipment to the environmental lab. Station 3Cl was resampled on 12/12112 and sent to the lab which met the fourth quarter supplemental sampling requirement for this station.

Blanchard Sheep Meat (BSM) and Blanchard Goat Meat (BGM) were not available and were not provided by the rancher during the fourth quarter of 2012. These animals were not slaughtered. The REMP did obtain Blanchard Cow Meat (BCM) during this timeframe. These samples were supplemental.

4.1.5 OCEAN SURFACE WATER, DRINKING WATER, AND GROUNDWATER All water samples were collected as scheduled (including allowable variation) with the following exceptions:

Observation Well 02 (OW2) was dry during fourth quarter 2012. No monitoring well water sample could be obtained.

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

Replicate samples were taken from:

AVA - Avila Beach sand (3/22112)

7C2 - Seawater (6111112)

5F2- Milk (8/21112)

8S3 - Groundwater Well (12/20112)

The results of the analyses were within expected correlation.

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.

All analyzed REMP samples met the specified "a-priori" LLD requirements in 2012.

4.3 COMPARISON OF RESULTS AGAINST REMP REPORTING LEVELS NRC notification was required whenever a Reporting Level listed in Table 2.4 of this document was 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 isotopic concentrations were averaged over the calendar quarter for the purposes of this comparison, and that Reporting Levels applied only to DCPP plant related effluent radioactivity. Fukushima Japan event related isotopes were not DCPP plant related effluents and therefore did not apply to those reporting levels.

No REMP Reporting Levels were exceeded during this 2012 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 result concentration exceeds the MDC for that analysis.

4.4.1 Direct Radiation (Environmental TLDs)

Direct radiation is continuously measured at 31 locations surrounding DCPP using Panasonic UD-814 thermo-luminescent dosimeters (TLDs). These 31 locations are made up of29 indicator stations & 2 control stations. These dosimeters were collected every calendar quarter for processing. The preoperational and historical operating values were evaluated for adverse trends.

DCPP Environmental TLD standard quarter results were measurements of all environmental gamma radiation sources (cosmic, terrestrial, radon, etc) at each station during the deployment period. Transient and lab storage background dose contributions were subtracted prior to reporting.

The unrestricted area surrounding DCPP was sparsely inhabited out to five miles from the site (ref 2012 Land Use Census in Section 8).

The ambient direct radiation levels within the DCPP plant site boundary (approximately 800 meter radius from U-l CTMT structure) were elevated at some locations (1S-1 thru IS-8) due to dry cask used fuel storage and an ISFSI loading campaign. ISFSI projects completed the 2012 spent fuel loading campaign at ISFSI on 3-17-12. An evaluation of direct radiation measurements and member of public occupancy times within the site boundary indicated all federal criteria for member of public dose limits (IOCFR20.1301) were conservatively met. It should be noted that the following Environmental TLD locations were all within the DCPP site boundary and were not located within the unrestricted area: OSl, OS2, WN1, lSI, 2Sl, 3S1, 4S1, 5S1, 5S3, 6S1, 7S1, 8S1, 8S2, 9S1, MTl, and lSI through IS8.

The first graph (provided next page) illustrated overall trending of environmental TLDs with regard to distance from the DCPP plant site. Inner ring, outer ring, special interest, and control stations were combined and averaged to obtain a single standard quarter value for each represented plot line.

It should be noted that inner and outer ring TLD averages remained within and trended with pre-operational ranges. It should also be noted that ISFSI loading and the Fukushima Japan nuclear accidents had not affected these inner and outer ring trending results.

The second graph (provided next page) illustrated averaged environmental TLD results from the southeast sector (stations 8S1, 8S2) and northwest sector (stations OSl, OS2, OBI). These sectors were chosen for graphical trending due to historical wind rose results for the site. The southeast and northwest sectors have contained the highest historically averaged wind directions and therefore would have the most impact on environmental TLD results.

Averaged control stations (4D1, 5F1) were provided for natural background reference.

Appendix B provides individual station environmental TLD standard quarter dose results.

Appendix B also provides an individual station historical average along with lowlhigh ranges from 1987 to 2011 for comparison of the 2012 data.

No adverse trends were noted in 2012 Environmental TLD monitoring.

Direct radiation was continuously measured at 8 stations surrounding the Independent Spent Fuel Storage Installation (ISFSI) using Panasonic UD-814 thermo-luminescent dosimeters (TLDs).

These 8 stations were located directly adjacent and exterior to the ISFSI protected area, with 2 stations on each of the four sides of the ISFSI. It should be noted that these stations and the ISFSI were well within the DCPP site boundary and were not located within the unrestricted area. These dosimeters were 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) equipment in seatrains at the ISFSI pad prior to an outage. These seatrains of RAM were removed prior to the first load of spent fuel canisters. In May 20 I 0, DCPP began the second ISFSI loading of spent fuel canisters. A third ISFSI loading campaign occurred during the first quarter of 20 12 and ended on 3117/2012. The ambient direct radiation levels within the DCPP plant site boundary near the ISFSI were elevated due to dry cask used fuel storage. An evaluation of direct radiation measurements and member of public occupancy times surrounding the ISFSI indicated all federal criteria for member of public dose limits (1 OCFR20.130 1) were conservatively met. No adverse trends were noted at the DCPP inner ring stations due to ISFSI for 2012 as indicated by the previous graphs. It should be noted that the DCPP inner ring TLD results tracked in correlation with normal Environmental TLD outer ring, special interest, and control station fluctuations. It should also be noted that DCPP inner ring TLD results remain within pre-operational ranges.

4.4.2 Airborne Air particulate and radioiodine samples were collected weekly from six indicator stations (MT1, OS2, lSI, 7D1, 8Sl, and 8S2) in the DCPP environs and one control station (5Fl). A total of364 air particulate filters and 364 iodine cartridges were collected and analyzed as part of the normal REMP.

Natural occurring gross beta activity was detected in 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. Normal background gross beta values ranged from 4.8E-3 3

to 9.5E-2 pCi/m

The gross beta activities detected at the air sampling stations were tabulated in AppendixA.

Gamma isotopic analyses were performed on quarterly composites of the air particulate filters from each of the REMP air stations. The midpoint date of the quarter was used to label the composite. Appendix A summarized those results.

A total of364 normal REMP weekly charcoal cartridges were analyzed for 1-131. No 1-131 was detected in 2012.

Appendix A summarizes overall REMP air sampling results.

Appendix C contains each air sampling station data result.

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 89190, Iron-55, and Nickle-63.

No plant related radionuc1ides were detected in any of the 2012 drinking water samples.

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

Ocean Surface Water Ocean surface water samples were collected monthly from stations OUT, DCM, and control station 7C2. The samples were analyzed for gamma emitters, gross beta, tritium, Total Strontium 89/90, Iron-55, and Nickle-63.

No DCPP related radionuclides were detected in any of the 2012 surface water samples.

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

Groundwater As part of the nuclear industry NEI 07-07 Groundwater Protection Initiative (GPI); DCPP began sampling various water sources in 2006. These sources included onsite monitoring wells (OWl, OW2, DY1, & 8S3), an aquifer well (WW2), a creek (5S2 & WN2), and a groundwater spring (lA2).

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

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

One shallow (approximately 70 feet deep) subsurface monitoring well was located southeast at approximately 0.3 miles from the power block. This monitoring well was labeled DCSF96-1 (station 8S3).

Tritium was detected in one sample of 8S3 monitoring well during fourth quarter of 20 12 due to rainwater washout of gaseous tritium exiting the plant vent system (via an approved discharge path).

Cs-137 was detected in one sample of 8S3 monitoring well during fourth quarter of 20 12 due to rainwater washout of Fukushima isotopes (Cs-13 7) during March of 20 11 (ref 2011 DCPP AREOR). This 2011 Fukushima Cs-137 deposition and 30 year half-life was eventually detected in this well. The 2012 8S3 Cs-137 concentrations correlated with sampling of rain events during the March 2011 fallout event.

Stations 5S2, WN2, and 1A2 were discussed in the previous Drinking Water paragraphs.

Three shallow (approximately 37 to 73 feet deep) subsurface monitoring wells were 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 were labeled Observation Well 01 (OWl), Observation Well 02 (OW2), and Drywelll15 (DY1).

These monitoring wells contained low levels of tritium throughout 2012 due to rainwater washout of gaseous tritium exiting the plant vent system (via an approved effluents discharge path). These tritium concentrations were evaluated and were not due to a plant system leak or spill.

Cs-137 was detected in two samples of the DY1 monitoring well due to rainwater washout of Fukushima isotopes (Cs-137) during March of2011 (ref2011 DCPP AREOR). This 2011 Fukushima Cs-137 deposition and 30 year half-life was eventually detected in this well. The 2012 DY1 Cs-137 concentrations correlated with sampling of rain events during the March 2011 Fukushima fallout event.

Further reporting of these monitoring wells was provided in Section 5.2 of this report.

Two additional groundwater monitoring wells (stations GW1 and GW2) were installed along the western side of the DCPP site on December 14, 2011. DCPP REMP began sampling these new wells during the first quarter of2012.

Tritium was detected in two quarterly samples ofGWl monitoring well during 2012 due to rainwater washout of gaseous tritium exiting the plant vent system (via an approved effluents discharge path). These tritium concentrations were evaluated and were not due to a plant system leak or spill.

Further reporting of these monitoring wells was provided in Section 5.2 of this report.

4.4.4 Ingestion Marine Biological Samples Fish samples were collected quarterly from stations DCM, PON, POS, 7C2 (control), and a local market (7D3 or 2F1).

Mussels were collected quarterly from stations DCM, 7C2, and POS. Mussels were collected annually from station PON (due to small mussel bed / availability at station PON).

A summary of these samples (required and supplemental) is described in Table 2.1. 'A summary of sample results is provided in Appendix A and individually listed in Appendix C.

Cs-137 was detected in three samples offish (station 2F1, PON, and 7D3) most likely due to rainwater washout of Fukushima Cs-137 isotopes during March of2011 (ref2011 DCPP AREOR).

For reference, the March 2011 Central Coast rainwater Cs-137 concentrations ranged from 2.4 pCi/Liter to 25.4 pCilLiter due to Fukushima event fallout. This 2011 Cs-137 deposition and 30 year half-life was eventually detected in fish. The 2F1 market fish albacore tuna sample correlated with Cs-137 concentrations in albacore tuna samples obtained during the same time period in San Diego California which were scientifically attributed to the Fukushima event. Station 2F 1 and PON fish samples were taken during second quarter of2012. The station 7D3 fish sample was taken during fourth quarter 2012 and also correlated with Fukushima event or historical nuclear weapons testing fish Cs-13 7 concentrations.

As previously stated, another source of Cs-13 7 fish concentrations in San Luis Obispo County has historically been due to fallout from national atmospheric nuclear weapons testing prior to DCPP operation. DCPP REMP sampling has routinely detected Cs-137 in local fish every year or two.

Those Cs-137 fish concentrations ranged from 3 pCi/kg to 14 pCi/kg historically. Considering the Cs-137 isotopic half-life of approximately 30 years, these 2012 fish concentrations were within this historical range. Many fish samples taken from locations outside the influence of DCPP also indicate Cs-137 concentrations. Therefore, the REMP attributes the fish Cs-137 concentrations to either Fukushima related or pre-1990's nuclear weapons testing fallout.

All other marine fish and mussel samples did not detect any DCPP related radionuclides during 2012.

Marine Aquatic Vegetation Supplemental marine aquatic kelp sampling was performed quarterly at REMP sample stations DCM, PON, POS, and 7C2 (control). No DCPP related isotopes were detected in 2012.

Supplemental intertidal algae sampling was performed quarterly at REMP sample stations DCM and 7C2 (control). No DCPP related isotopes were detected in 2012.

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

Ocean Sediment and Recreational Beach Sampling Ocean sediment samples were collected annually from stations DCM and 7C2. Gamma Spec, Total Strontium 89/90, Iron-55, and Nickle-63 were analyzed.

Supplemental recreational beach sand samples were collected semi-annually from stations Avila Beach (AVA), Montana de Oro Spooner's Cove (MDO), Pismo Beach near pier (PMO), Cayucos Morro Strand State Beach (CYA), and Cambria Moonstone Beach (CBA). Each sample was analyzed for gamma emitting radionuclides, Total Strontium 89/90, Iron-55, and Nickle-63.

Only natural occurring isotopes where detected in the ocean sediment and recreational beach sand samples collected for 2012.

4.4.5 Food Crops (Vegetation)

Samples of broad leaf vegetation were collected monthly (when available) from two indicator stations (7Cl and 7Gl), and one control location (5F2). Samples were also collected quarterly from residence gardens at stations 3Cl and 6C1. The samples were analyzed for gamma emitting radionuclides and for Iodine-131 on edible portions.

Cs-137 was detected in 2012 vegetation samples from 3Cl, 6Cl, and 7Gl due to rainwater washout of Fukushima Cs-137 isotopes during March of2011 (ref2011 DCPP AREOR). These Cs-137 isotopes were transported to the west coast of the United States via the jet stream in March 2011.

This 2011 Cs-137 deposition (along with 30 year half-life) was absorbed by plant life and the soil.

DCPP REMP has routinely detected Cs-137 in plant life since March of2011 due to this Fukushima event. Stations 3Cl, 6Cl, and 7G 1 are not in close proximity to the plant site.

Additional 2011 Fukushima event control sampling was conducted in Atascadero, California (20 miles north of DCPP) and reported in the 2011 DCPP AREOR. Fukushima related 1-131 and Cs-137 isotopes were detected in various Atascadero vegetation samples in 2011 to confirm Fukushima contribution.

A summary of the vegetation sample results are provided in Appendix A and individual results listed in Appendix C. DCPP related isotopes were not detected in vegetation.

4.4.6 Milk There are no milking animals within S miles of the plant site. In cases where milk sampling is not available, the REMP permits 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 1S 1.

Supplemental samples of milk were collected monthly from Cal Poly Farm (station SF2). The samples were analyzed for gamma emitting radionuclides, Iodine-131, and Total Strontium 89/90.

Milk samples were collected monthly from station SF2 regardless of the availability of milk stations within S miles of the plant.

No DCPP related radionuclides were detected in station SF2 milk samples during 2012.

A summary of the sample results are provided in Appendix A and individual results listed in Appendix C.

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

Samples of livestock meat were collected from the Blanchard Ranch in 2012. These samples were Blanchard cow meat (BCM), Blanchard sheep meat (BSM), and Blanchard goat meat (BGM).

One wild deer meat sample (station IDM) was supplied by a landowner in 2012.

Additional Fukushima event meat sampling was conducted of Hearst Ranch meat which was located approximately 37 miles north of the DCPP site. This Hearst Ranch meat was free range, grass fed beef. This new REMP station code was HCM and provided a control location far from the DCPP site (approximately 37 miles from the site).

Cs-137 was detected in these 2012 meat samples due to the Fukushima Japan nuclear accidents.

These Cs-137 isotopes were transported to the west coast of the United States via the jet stream in March 2011. Vegetation uptake and subsequent digestion by the animals were the source of these Cs-137 isotopes into the meat (ref2011 DCPP AREOR). A summary of the sample results are provided in Appendix A and individual results listed in Appendix C.

4.5 CS-137 ISOTOPIC DETECTION DUE TO THE FUKUSHIMA PREFECTURE JAPAN, DAI-ICHI NUCLEAR POWER STATION ACCIDENTS.

On March 11 th, 2011 the Tohoku-Oki earthquake (magnitude 9.0 Mw ) and tsunami struck the east coast of Japan. The tsunami associated with this event caused nuclear accidents at the Dai-Ichi Nuclear Power Station in Fukushima Prefecture, Japan. Isotopic releases occurred in Japan and were carried by the jet stream to the west coast of the United States in March 2011.

The DCPP REMP initiated numerous supplemental sampling in 2011 to establish Fukushima contributions to DCPP isotopic background concentrations (ref2011 DCPP AREOR). Fukushima related isotopes were first detected by the DCPP REMP beginning on March 17th , 2011. Airborne isotopic concentrations were detected from March 17th thru April 20th of 20 11. Various concentrations ofl-131, 1-132, Te-132, Cs-134, and Cs-137 were identified as Fukushima fallout along the Central Coast in March-ApriI2011.Due to the relatively short half-life of the previously mentioned isotopes; they are no longer detected in 2012 DCPP REMP sampling except for Cs-137 which has an approximate 30 year half-life.

Supplemental 2011 DCPP environmental sampling included the following (for reference):

Capture of rain in March and April 2011 for isotopic analysis (ref2011 DCPP AREOR).

Additional 2011 air sampling at stations OS2, SF 1, 7D 1, and 8S 1. This air sampling was conducted with additional air samplers at an increased flow rate (2.0 scfm) and increased volumes. The station samples were analyzed each week for gamma isotopic and strontium which is different than normal REMP sampling protocols (ref 20 11 DCPP AREOR)

Additional 2011 milk and vegetation sampling was conducted at station SF2 (ref2011 DCPP AREOR).

Additional 2011 vegetation sampling was conducted outside the possible influence of DCPP within Atascadero, California (20 miles north of DCPP). Fescue grass, milk thistle, miner's lettuce, and acorns were sampled in Atascadero (station A TAS) to establish additional control vegetation samples (ref 20 11 DCPP AREOR).

Additional 2011 & 2012 meat control sampling was conducted outside the possible influence of DCPP at Hearst Ranch which is located 37 miles north of DCPP near San Simeon, California. Publically offered Hearst Ranch meat (station HCM) was free range, grass fed beef and provided a control for Blanchard meat (stations BCM, BSM, and BGM).

Sticky pads (1ft by 3ft) were placed at OS2 and 5Fl in 2011 to monitor ground deposition of Fukushima isotopes. These sticky pads were pulled weekly from 3-23-11 until 5-4-11 for isotopic analysis (ref 20 11 DCPP AREOR).

The above supplemental REMP environmental air, rain, vegetation, milk, meat, and sticky pad samples were obtained during 2011. These samples identified detectable concentrations of isotopes that could be related to operation of Diablo Canyon NPS.

The DCPP REMP detected cesium within milk, vegetation, and meat throughout 2011.

The DCPP REMP continued to detect cesium within groundwater, fish, vegetation, and meat throughout 2012.

Given the following facts, the 2012 detectable Cs-137 isotopic concentrations were not a result of Diablo Canyon Nuclear Power Station operation:

1. The quantities of radioactive airborne effluents from Diablo Canyon NPS during 2012 did not increase significantly compared to year 2010 (prior to Fukushima).

2. Prior to 2011, REMP sample results had not detected the presence of short half-life 2011 isotopes at these concentrations over the last ten years ofDCPP operation (e.g. 1-131, 1-132, Te-132, Cs-134).

3. The 2012 Cs-137 isotopes detected correspond to timelines related to the Fukushima Prefecture Japan nuclear accidents and the jet stream deposition of those isotopes to the west coast of the United States in March 2011.

4. The 2012 Cs-137 concentrations detected within the indicator samples were also identified in the normal REMP control samples and supplemental Fukushima event 2011 sampling far from Diablo Canyon NPS.

5. These 2011 Fukushima related isotopes were also detected by other Government Agencies, Nuclear Power Sites, and Colleges across the United States in 2011.

As such, the atypical Cs-137 radionuclide detection in both indicator and control samples is credibly attributed to the trans-Pacific transport of airborne releases from Dai-Ichi, Fukushima following the March 11,2011 Tohoku-Oki earthquake or national atmospheric nuclear weapons testing pre-1990's fallout. Cs-137 concentrations were not related to the operations of Diablo Canyon NPS. Cs-137 continues to be detected in the Central Coast environment during 2012 due to it's half-life of approximately 30 years.

5.0 GROUNDWATER 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.

Groundwater gradient 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 is west toward the Pacific Ocean or northwest toward Diablo Creek. Any groundwater present beneath the DCPP power block is not used as a source of drinking water. It should be noted that this DCPP power block groundwater gradient and Diablo Creek discharge into the Pacific Ocean.

5.1 NEI 07-07 GROUNDWATER PROTECTION INITIATNE- VOLUNTARY REPORTING 5.1.1 NEI 07-07 Objective 2.4 (b), Annual Reporting:

Document in the AREOR all on-site ground water sample results that are included in the REMP as described in the DCPP Offsite Dose Calculation Manual (ODCM).

Onsite groundwater monitoring points are described in the REMP and reported in this 2012 Annual Radiological Environmental Operating Report (ARE OR) as follows:

Observation Well 01 (OWl), Observation Well 02 (OW2), Drywelll15 (DY1), DCSF96-1 (8S3),

Water Well 02 (WW2), Groundwater Well 1 (GW1), Groundwater Well 2 (GW2), and Diablo Creek Outlet (WN2) were used for Groundwater Protection Initiative (GPI) data reporting and were described in 2012 DCPP ARE OR Table 2.1.

A summary of the 2012 GPI monitor well sample results are summarized in Appendix A and individual results listed Appendix C.

DCPP REMP sampled all available groundwater regardless of present or future use.

The ground water beneath the DCPP power block is not used as a source of drinking water.

5.2 ADDITIONAL GROUNDWATER SAMPLING OVERVIEW:

Ground water monitoring was reported in accordance with the nuclear industry NEI 07-07 Groundwater Protection Initiative and the REMP. Concentrations of tritium were detected in three monitoring wells beneath the DCPP power block. This tritium was coming from the rain-washout of gaseous tritium exiting the plant vent system via an approved effluent discharge route.

DCPP has conducted rain-washout studies to document this phenomenon. These monitoring wells consisted of French drain systems that discharge into the associated monitoring well (OWl, OW2, or DY1). Rain communicated with these French drain systems via building structure to ground interfaces. Once rain water entered the monitoring wells, the water remained stagnant until another rain event caused transport. Subsequent quarterly sampling routinely indicated consistent tritium values due to monitoring well stagnation.

DYI routinely experienced the highest tritium rain-washout concentrations due to its close proximity to the plant vent discharge points.

OWl was connected to subsurface groundwater flow fissures and routinely trends with rain fall.

OW2 was routinely dry or stagnant. Very little groundwater was detected in OW2.

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.

The specific ranges of tritium detected in these power block monitoring wells for 2012 were as follows:

OWl - Observation Well 01 ( 886 to 1,320 pCiIL ) 4 of 4 samples collected for tritium analysis.

OW2 - Observation Well 02 ( 1,340 to 1,510 pCi/L ) 4 of 4 samples collected for tritium analysis.

DY1 - Drywelll15 ( 18,000 to 19,100 pCiIL) 4 of 4 samples collected for tritium analysis.

Cs-137 was detected in 2 of 4 DYI samples but was attributed to 2011 Fukushima fall-out due to Cs-137 detection also in we1l8S3 (outside power block influence).

No other DCPP related isotopes were detected in OWl, OW2, or DYI.

Two new down-gradient monitoring wells were added to the REMP in 2012.

Groundwater Well 1 (GW1) is located between the DCPP protected area and the cliff boundary of the Pacific Ocean. It is down gradient of Unit One power block. This well opening is located at approximately 85' above sea level and is approximately 85' deep to prevent sea water intrusion.

Groundwater Well 2 (GW2) is located between the DCPP protected area and the cliff boundary of the Pacific Ocean. It is down gradient of Unit Two power block. This well opening is located at approximately 85' above sea level and is approximately 85' deep to prevent sea water intrusion.

The specific ranges of tritium detected in GWlIGW2 monitoring wells for 2012 were as follows:

GW1 - Groundwater WeIll ( 334 to 400 pCilL ) 2 of 4 samples collected for tritium analysis. This tritium was evaluated and attributed to the rain-washout of gaseous tritium exiting the plant vent system via an approved effluent dischatge route.

GW2 - Groundwater Well 2 (non-detected) 4 of 4 samples collected for tritium analysis.

No other DCPP related isotopes were detected in GWI or OW2.

Monitoring We1l8S3 was sampled 5 times in 2012.

Tritium was detected once out of five samples (322 pCilL) at 8S3. This tritium was evaluated and attributed to the rain-washout of gaseous tritium exiting the plant vent system via an approved effluent discharge route.

Cs-137 was detected once out of five samples (2.76 pCilL) at 8S3. This Cs-137 was attributed to 2011 Fukushima fall-out.

No other DCPP related isotopes were detected in 8S3.

All other samples of groundwater at 1A2, WW2, and WN2 did not indicate the presence of tritium or any other DCPP 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 via an approved discharge pathway.

For reference, the following equipment was placed into this OSGSF on the following dates:

3/2/08 (outage 2RI4), four DCPP Unit Two (U-2) Steam Generators

2/14/09 (outage IRIS), four DCPP Unit One (U-I) Steam Generators

11/6/09 (outage 2RlS), one DCPP Unit Two (U-2) Reactor (Rx) Head

10/23/10 (outage lRI6), one DCPP Unit One (U-l) Rx Head As of 10/23/1 0, the OSGSF contains eight old Steam Generators and two old Rx Heads.

Construction repairs were made to the OSGSF in 2011 to prevent rainwater from entering the OSGSF. Specific repairs involved OSGSF vertical wall crack repairs and installation of roof gutters around the east and south side of the OSGSF. These repairs have been successful for prevention of rainwater intrusion into the OSGSF.

The OSGSF sumps were inspected quarterly in 2012 by REMP personnel.

No water was found in any OSGSF sumps during 2012 inspections.

2. Quality Assurance Programs for Inter-laboratory, Intra-laboratory and Third Party Cross-Check In addition to internal and client audits, our laboratory participates in annual performance evaluation studies conducted by independent providers. We routinely participate in the following types of performance audits:

Proficiency testing and other inter-laboratory comparisons

Performance requirements necessary to retain Certifications

Evaluation of recoveries of certified reference and in-house secondary reference materials using statistical process control data.

Evaluation of relative percent difference between measurements through SPC data.

We also participate in a number of proficiency testing programs for federal and state agencies and as required by contracts. It is our policy that no proficiency evaluation samples be analyzed in any special manner. Our annual performance evaluation participation generally includes a combination of studies that support the following:

US Environmental Protection Agency Discharge Monitoring Report, Quality Assurance Program (DMR-QA). Annual national program sponsored by EPA for laboratories engaged in the analysis of samples associated with the NPDES monitoring program.

Participation is mandatory for all holders of NPDES permits. The permit holder must analyze for all of the parameters listed on the discharge permit. Parameters include general chemistry, metals, BOD/COD, oil and grease, ammonia, nitrates, etc.

Department of Energy Mixed Analyte Performance Evaluation Program (MAPEP). A semiannual program developed by DOE in support of DOE contractors performing waste analyses. Participation is required for all laboratories that perform environmental analytical measurements in support of environmental management activities. This program includes radioactive isotopes in water, soil, vegetation and air filters.

ERA's MRAD-Multimedia Radiochemistry Proficiency test program. This program is for labs seeking certification for radionuclides in wastewater and solid waste. The program is conducted in strict compliance with USEPA National Standards for Water Proficiency study.

ERA's InterLaB RadCheM Proficiency Testing Program for radiological analyses. This program completes the process of replacing the USEPA EMSL-LV Nuclear Radiation Assessment Division program discontinued in 1998. Laboratories seeking certification for radionuclide analysis in drinking water also use the study. This program is conducted in strict compliance with the USEPA National Standards for Water Proficiency Testing Studies. This program encompasses Uranium by EPA method 200.8 (for drinking water certification in Florida/Primary NELAP), gamma emitters, Gross Alpha/Beta, lodine-131, naturally occurring radioactive isotopes, Strontium-89/90, and Tritium.

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 7 of60

ERA's Water Pollution (WP) biannual program for waste methodologies includes parameters for both organic and inorganic analytes.

ERA's Water Supply (WS) biannual program for drinking water methodologies includes parameters for organic and inorganic analytes.

Environmental Cross-Check Program administered by Eckert & Ziegler Analytics, Inc.

This program encompasses radionuclides in water, soil, milk, naturally occurring radioactive isotopes in soil and air filters.

GEL procures single-blind performance evaluation samples from Eckert & Ziegler Analytics to verify the analysis of sample matrices processed at GEL. Samples are received on a quarterly basis. GEL's Third-Party Cross-Check Program provides environmental matrices encountered in a typical nuclear utility REMP. The Third-Party Cross-Check Program is intended to meet or exceed the inter-laboratory comparison program requirements discussed in NRC Regulatory Guide 4.15, revision 1. Once performance evaluation samples have been prepared in accordance with the instructions provided by the PT provider, samples are managed and analyzed in the same manner as environmental samples from GEL's clients.

3. Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessment of each area of the laboratory is conducted in accordance with the pre-established schedule from Standard Operating Procedure for the Conduct of Quality Audits, GL-QS-E-001. The annual internal audit plan is reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GEL's QA program. Internal audits are conducted at least annually in accordance with a schedule approved by the Quality Systems Director. Supplier audits are contingent upon the categorization of the supplier, and mayor may not be conducted prior to the use of a supplier or subcontractor. Type I suppliers and subcontractors, regardless of how they were initially qualified, are re-evaluated at least once every three years.

In addition, prospective customers audit GEL during pre-contract audits. GEL hosts several external audits each year for both our clients and other programs. These programs include environmental monitoring, waste characterization, and radiobioassay. The following list of programs may audit GEL at least annually or up to every three years depending on the program.

The annual radiochemistry laboratory internal audit (12-RAD-001) was conducted in March 2012.

Two (2) findings, three (3) observations, and three (3) recommendations resulted from this

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 8 of60 assessment. In May, 2012, each finding was closed and appropriate laboratory staff addressed each observation and recommendation.

The Nuclear Procurement Issues Committee (NUPIC) follow up verification audit was conducted on October 16, 2012 through October 17, 2012. This Duke Energy/NUPIC QA audit was performed to verify that the six audit findings identified in the 2011 NUPIC audit had been successfully implemented.

The audit confirmed that the actions taken to the six findings have been adequately addressed by GEL. The Audit Report # 22837-A for Supplier Number 5644 has been posted on the NUPIC website.

4. Performance Evaluation Acceptance Criteria for Environmental Sample Analysis GEL utilized an acceptance protocol based upon two performance models. For those inter-laboratory programs that already have established performance criteria for bias (Le., MAPEP, and ERA/ELAP) , GEL will utilize the criteria for the specific program. For intra-laboratory or third party quality control programs that do not have a specific acceptance criteria (i.e. the Eckert-Ziegler Analytics Environmental Cross-check Program), results will be evaluated in accordance with GEL's internal acceptance criteria.

5. Performance Evaluation Samples Performance Evaluation (PE) results and internal quality control sample results are evaluated in accordance with GEL acceptance criteria. The first criterion concerns bias, which is defined as the deviation of anyone result from the known value. The second criterion concerns precision, which deals with the ability of the measurement to be replicated by comparison of an individual result with the mean of all results for a given sample set.

At GEL, we also evaluate our analytical performance on a regular basis through statistical process control (SPC) acceptance criteria. Where feasible, this criterion is applied to both measures of precision and accuracy and is specific to sample matrix. We establish environmental process control limits at least annually.

For Radiochemistry analysis, quality control evaluation is based on static limits rather than those that are statistically derived. Our current process control limits are maintained in GEL's AlphaUMS. We also measure precision with matrix duplicates and/or matrix spike duplicates.

The upper and lower control limits (UCL and LCL respectively) for precision are plus or minus three times the standard deviation from the mean of a series of relative percent differences. The static precision criteria for radiochemical analyses are 0 - 20%, for activity levels exceeding the contract required detection limit (CRDL).

6. Quality Control Program for Environmental Sample Analysis GEL's internal QA Program is designed to include QC functions such as instrumentation calibration checks (to insure proper instrument response), blank samples, instrumentation backgrounds, duplicates, as well as overall staff qualification analyses and statistical process controls. Both quality control and qualification analyses samples are used to be as similar as the matrix type of those samples submitted for analysis by the various laboratory clients. These performance test samples (or performance evaluation samples) are either actual sample

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 9 of60 submitted in duplicate in order to evaluate the precision of laboratory measurements, or fortified blank samples, which have been given a known quantity of a radioisotope that is in the interest to GEL's clients.

Accuracy (or Bias) is measured through laboratory control samples and/or matrix spikes, as well as surrogates and internal standards. The UCLs and LCLs for accuracy are plus or minus three times the standard deviation from the mean of a series of recoveries. The static limit for radiochemical analyses is 75 - 1250/0. Specific instructions for out-of-control situations are provided in the applicable analytical SOP.

GEL's Laboratory Control Standard (LCS) is an aliquot of reagent water or other blank matrix to which known quantities of the method analytes are added in the laboratory. The LCS is analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements. Some methods may refer to these samples as Laboratory Fortified Blanks (LFB). The requirement for recovery is between 75 and 125% for radiological analyses excluding drinking water matrix.

Bias (0/0) = (observed concentration)

100 0/0 (known concentration)

Precision is a data quality indicator of the agreement between measurements of the same property, obtained under similar conditions, and how well they conform to themselves. Precision is usually expressed as standard deviation, variance or range in either absolute or relative (percentage) terms.

GEL's laboratory duplicate (OUP or LCSO) is an aliquot of a sample taken from the same container and processed in the same manner under identical laboratory conditions. The aliquot is .

analyzed independently from the parent sample and the results are compared to measure precision and accuracy.

If a sample duplicate is analyzed, it will be reported as Relative Percent Difference (RPO). The RPO must be 20 percent or less, if both samples are greater than 5 times the MOC. If both results are less than 5 times MOC, then the RPO must be equal to or less than 100%. If one result is above the MOC and the other is below the MOC, then the RPO can be calculated using the MOC for the result of the one below the MOC. The RPO must be 1000/0 or less. In the situation where both results are above the MOC but one result is greater than 5 times the MOC and the other is less than 5 times the MOC, the RPO must be less than or equal to 20%. If both results are below MOC, then the limits on % RPO are not applicable.

Difference (%) = (high duplicate result - low duplicate result)

100 0/0 (average of results)

7. Summary of Data Results During 2012, forty-three (43) radioisotopes associated with seven (7) matrix types were analyzed under GEL's Performance Evaluation program in participation with ERA, MAPEP, and Eckert &

Ziegler Analytics. Matrix types were representative of client analyses performed during 2012. Of the four hundred forty-four (444) total results reported, 980/0 (433 of 444) were found to be acceptable. The list below contains the type of matrix evaluated by GEL.

12. Corrective Action Request and Report (CARR)

There are two categories of corrective action at GEL. One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002. A formal corrective action is initiated when a nonconformance reoccurs or is so significant that permanent elimination or prevention of the problem is required. Formal corrective action investigations include root cause analysis.

GEL includes quality requirements in most analytical standard operating procedures to ensure that data are reported only if the quality control criteria are met or the quality control measures that did not meet the acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement. Recording and documentation is performed following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.

Any employee at GEL can identify and report a nonconformance and request that corrective action be taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002. In the event that correctness or validity of the laboratory's test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of the discovery.

Table 8 provides the status of CARRs for radiological performance testing during 2012. It has been determined that causes of the failures did not impact any data reported to our clients.

& DISPOSITION PE FAILURE CARR 120306-667 The low bias associated with the tritium result for RAD-88 initiated an investigation of the liquid scintillation detector ISO Documentation of PT Failures in used for the original reported result after the original vials RAD-88 Study - Tritium in Water were recou,nted on a different detector and met acceptance criteria. The tritium efficiency for the detector was reviewed and a slight low bias was observed. A service call was initiated.

Tritium and carbon-14 efficiencies were calculated on all liquid scintillation detectors to ensure that service was not required.

No other deficiencies were noted. The data reported using this detector was also reviewed and were deemed acceptable as originally reported In the future, the efficiency of each detector will be monitored monthly in order to rapidly identify any change that may require service.

A second PT was successfully analyzed for this matrix.

CARR120831-715 Barium-133 All data were reviewed and it appears that the cause of the ISO Documentation of PT Failures in high bias was due to the calibration standard.

RAD-90 Study - Barium-133 and The reported result was counted on a detector that omitted Radium-226 the Hg-203 nuclide from the efficiency calibration due to its short half-life and an inability to accumulate 10,000 counts in a reasonable amount of time. The duplicate sample in the batch counted on a detector that had the Hg-203 point included in its efficiency calibration and generated a result of 64.83 pCi/L. This result compares well with the assigned value of 65 pCi/L.

Radium-226 After a review of the data, an apparent reason for this discrepancy could not be determined. Multiple steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within control.

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 56 of 60 Two sample duplicates were also prepared and counted along with the reported result. Both results fell well within the acceptance range Actions to Prevent Potential Occurrence or Recurrence:

Barium-133 In the future additional points will be included in the efficiency curve to better estimate the efficiencies across the entire energy spectrum.

Radium-226 The laboratory must assume an unidentified random error caused the high bias because all quality control criteria were met for the batch. The lab will continue to monitor the recoveries of this radionuclide to ensure that there are no issues.

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 57 of60 CARR 120711-694 and 698 For Failures of MAPEP 26 Study for MAPEP-12-RdF26 Uranium 234/233 in Filters and Uranium-234/233 Vegitation After a thorough review of the data, the root cause of the low bias on the reported values was due to a high counting uncertainty. The counting uncertainty achieved for the U-233/4 results was approximately 100% of the reported results.

Since the Relative Error Ratio between the result and the true value was 1.72, this indicates that the measured result is within the uncertainty of the measurement.

Update January 2013 Originally, it was suspected that the failure of the low bias on the reported values was due to a high counting uncertainty.

The counting uncertainty achieved for the U-233/4 results was approximately 100% of the reported results. However, after the receipt of a similar failure in MAPEP 27 and a conversation with Mr. David Sill of the RESL Laboratory, it is certain that the aliquot used to analyze the sample was insufficient to detect the Uranium-234/233 spiked onto the filter (which is directly related to the high counting uncertainty).

MAPEP-12-RdV26 Uranium-234/233 After a thorough review of the data, the root cause of the low bias on the reported values was due to a high counting uncertainty. The counting uncertainty achieved for the U-233/4 results was approximately 60% of the reported results.'

Since the Relative Error Ratio between the result and the true value was 1.14, this indicates that the measured result is within the uncertainty of the measurement.

Permanent Corrective/Preventive Actions or Improvements:

Since guidance on acceptable uncertainties or Action Levels are not provided, to avoid potential warnings and failures due to high counting uncertainty in the future, our internal review process has been adjusted.

If the result has measurable activity but a low count rate, the count time will be extended and the sample re-analyzed with a larger aliquot to achieve better counting statistics.

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 58 of60 Root Cause Analysis of MAPEP-12-MaS27 CARR121127-742 Selenium MAPEP 27 Unacceptable and After a review of the data, a definitive reason for this Warning - Selinium, Gross Alpha discrepancy could not be determined. However, it is suspected that something occurred during the digestion of the batch to produce the lower recovery. The following steps were taken to ensure that this was an isolated occurrence and that our overall process is within control.

Actions Taken: MAPEP-12-MaS27 Selenium The laboratory must assume an unidentified random error caused the lower result. However, closer attention must be paid to the matrix QC failures. In the future, the samples should be re-extracted to confirm results prior to reporting.

MAPEP-12-GrF27 Gross Alpha Prior to counting, this filter was taken through the opening and labeling procedures specified in CARR120118-659. It is not suspected that previous Gross Alpha MAPEP issues contributed to this failure. While reviewing results from previous studies, a low bias was observed. It was suspected that this bias was due to a difference in instrument efficiency due to the filter media. To investigate further, a previous MAPEP filter containing activity was counted and used to establish an efficiency. When applied to the counts of MAPEP 27, the result were acceptable but the low bias was still observed. Source standards were then created using blank filter media from previous MAPEP studies. The blank filters were spiked with Th-230 and counted to determine an average efficiency. When this efficiency was applied to the MAPEP 27 count, the result fell well within the acceptance range. Using the blank filter to create an instrument efficiency is part of the study instructions as an option. This efficiency is much more accurate than what was used and will be used for future MAPEP studies.

Actions taken: MAPEP-12-GrF27 Gross Alpha Since using the blank filter to create an instrument efficiency is part of the study instructions, it will be used for future MAPEP studies. GEL found that this efficiency is much more accurate than the one previously used.

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 59 of60 CARR 121127-743 MAPEP-12-RdF27 MAPEP 27 Study Unacceptable and Uranium-234/233 Warning ratings for U234/233 in Filter Upon notification of the failures, the data were reviewed again for accuracy. Investigations on quality control checks and trending were preformed to ensure that the low bias was isolated to the MAPEP sample procedure and not indicative of a systematic failure.

Also, an additional MAPEP-12-RdF27 filter was obtained and prepared per standard protocol. Based on the recommendations from Mr. David Sill of the RESL laboratory, the entire filter was used for analysis. The U-233/234 and U-238 results for this analysis were 98% of the known values.

The cause of the failure was the limited sample amount used to prepare the initial sample. Multiple aliquots had been removed from the digested filter for other analyses, the RESL Laboratory had had prepared this sample as a single analysis.

Action Taken: MAPEP-12-RdF26 and MAPEP-12-RdF27 Uranium-234/233 Since guidance on acceptable uncertainties or Action Levels are not provided, to avoid potential warnings and failures due to high counting uncertainty in the future, our internal review process has been adjusted.

If the result has measurable activity but a low count rate, the count time will be extended and/or the sample re-analyzed using a larger sample aliquot to achieve better counting statistics. Although the MAPEP instructions are written such that the laboratory should have confidence in using smaller aliquots and still attain sufficiently low counting uncertainties, it is now our understanding that the design of the MAPEP filter program requires the analysis of a complete filter aliquot for each parameter analyzed.

GEL will procure from MAPEP a filter for each parameter, analyze the entire filter for each parameter, and no longer perform batch duplicates for filter analysis of MAPEP samples.

CARR121109-744 MAPEP-12-MaS26 & MAPEP-12-MaS27 Co-57 MAPEP 27 Study for biased high GEL received warnings for Co-57 results in the soil matrix in trends of Cobalt-57 the past two testing rounds of the MAPEP. While Co-57 received warning flags all other gamma emitting isotopes in the soil matrix had acceptable results. Due to a potential trend, a corrective action was opened.

After receiving the results from MAPEP-27 and a second biased high result for Co-57, a thorough review of our process

P.O. Box 30712, Charleston, SC 29417 2012 ANNUAL QUALITY ASSURANCE REPORT Page 60 of60 was conducted. This review indicated an issue associated with the calibration correction factors (absorption factors or density corrections) applied to results due to differing densities between the sample and the calibration standard. A potential 20% positive bias for Co-57 (122 keV) was observed. Note: This bias was within the acceptable uncertainty of the method (+/- 25%) for duplicate results.

Results for Am-241 (59.5 keV) were also reviewed to ensure that biases were not observed.

Action Taken: MAPEP-12-MaS26 & MAPEP-12-MaS27 Co-57 The reported results compared very well to the reference values for both MAPEP-26 and MAPEP-27 (-97% and 1010/0, respectively). Since absorption factors (or density corrections) are only applied to our 100 ml aluminum can geometry for soils, no other matrices were impacted. A review of the annual analytical data for this isotope indicated that the reported data to clients were not impacted by this bias.

8.0 DCPP LAND USE CENSUS This page intentionally left blank 2012 DCPP 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 2012. The land use census is based on Nuclear Regulatory Commission (NRC) Regulatory Guide 4.B, "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.ID11, "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 B 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 2012 Land Use Census was conducted via a helicopter over-flight and landowner telephone I personal interviews. The helicopter over-flight was conducted on November 5th ,

2012. The telephone I personal interviews were conducted November 2th through November 29th , 2012. Eight individual landowners or tenants were contacted.

Milk:

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

Residences:

The nearest residence, relative to all sectors, was a small trailer located in the NW sector about 1.93 kilometers (1.2 miles) from the plant. Ranch workers occupied this BLANCHARD residence approximately 1 month (per year) during cattle round-ups.

A total of fifteen residences were identified within the B-kilometer (5-mile) radius of the plant, which were confirmed or appear to have been occupied in 2012. One home was unoccupied during 2012. Six abandoned structures were also identified.

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

Gardens:

The land use census identified two household gardens greater than 50 square meters (500 square feet) that produced broadleafvegetation. The READ garden (REMP 3C1) was approximately % acre and located in the NNE sector at 7.0B kilometers (4.41 miles). The KOONZE garden (REMP 6C1) was approximately 500 square feet and located in the E sector at 7.24 kilometers (4.5 miles).

MELLO managed a farm in the ESE sector along the site access road coastal plateau.

The farm started at approximately 4.B km and extended to 7.2 km (3 to 4.5 miles) from the plant. This commercial farm produced no broad leaf vegetation. The farm area was about 100 acres of land with rotational planting. Commercial crops consisted of about 1000/0 cereal grass (oat hay) and straw grass. Less than 10 farm workers periodically occupied this area during the growing season.

Additional Land Use:

Much of the area outside the plant site-boundary was used for rotational cattle grazing by five separate cattle operations. For purposes of this census, the five cattle ranches were called BLANCHARD, SINSHEIMER, READ, ANDRE, and MELLO.

BLANCHARD had about 100 cattle outside the plant site-boundary and utilized the NW, NNW, N, and NNE sectors. About 80 yearling cattle were sold under the "Old Creek Ranch" label at local farmer's markets in 2012.

Additionally, BLANCHARD managed about 150 goats that were used for weed abatement in all landward sectors within the plant site-boundary. During 2012, approximately 100 baby goats were born and taken to Santa Margarita California where they were grass fed for one year. After one year, the 100 yearling goats were sold under the "Old Creek Ranch" label at local farmer's markets in 2012.

BLANCHARD also managed about 150 sheep outside the plant site-boundary in the NWand NNW sectors. These sheep were allowed to breed and the yearlings were sold under the "Old Creek Ranch" label at local farmer's markets in 2012.

The BLANCHARD's consumed about 75 pounds of these various meats during 2012.

"Old Creek Ranch" labeled meats were sampled quarterly by REMP personnel.

SINSHEIMER had 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 2012.

READ had about 110 adult cattle and 110 calves outside the plant site-boundary in the NNE sector. About 110 yearling cattle were sold under the "Old Creek Ranch" label at local farmer's markets in 2012.

ANDRE had about 80 cattle outside the plant site-boundary in the ENE sector. About 80 calves were sold to mass market in 2012. ANDRE did not slaughter any cattle in 2012 for personal consumption.

MELLO managed about 800 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 2012. MELLO did not slaughter any cattle in 2012 for personal consumption.

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

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

There was 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 was near Spooner's Cove.

Approximately 713,000 people visited Montana de Oro State Park via day use permit.

Approximately 22,000 people spent the night at Islay Creek Campground.

There was public access to hiking trails at the north and south ends of the PG&E property in 2012.

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

The Pecho Coast Trail was located at the south end of PG&E property and had about 2,500 visitors. The trail was approximately 3.7 miles long and led to the Point San Luis Lighthouse near Avila Beach. Access was controlled (by permission only) and conducted by docents. This trail was just slightly outside the 5 mile radius of the plant. Pecho Coast Trail hikes were only available on Wednesdays (about 20 people) and Saturdays (about 40 people).

30-40 Lighthouse keepers occupied the Lighthouse grounds on Tuesdays, Thursdays, and Saturdays from 0800-1600. The Lighthouse property was owned by the Harbor District.

Groundwater Protection Initiative (GPI) Review:

There were no site construction activities or spills that warranted changes to GPI monitoring frequencies, monitoring locations, contract lab analytical capabilities, or detection thresholds in 2012.

There were no changes in on-site or near site water usage that would result in potential unusual use of site ground water used as drinking !irrigation water in 2012.

Two new GPI monitoring wells (to the west of the site) were completed in December of 2011. These two new monitoring wells (station codes GW1 and GW2) were down gradient of the power block site along the Pacific Ocean boundary. Isotopic sampling of these new wells was conducted in 2012.

An updated Groundwater Gradient Analysis report was conducted by Cardno/Entrix Corporation in June 2012 with no abnormal findings reported.

Additional Onsite Information:

The following plant equipment was placed into the Old Steam Generator Storage Facility (OSGSF) for the duration of the plant operating license on the dates indicated below. It should be noted that the Old Steam Generator Storage Facility is located within the site boundary.

Unit One old steam generators (4 total) : 2-14-09 Unit Two old steam generators (4 total) : 3-2-08 Unit One old reactor head (1 total) : 10-23-10 Unit Two old reactor head (1 total) : 11-6-09 DCPP began loading of the on-site Independent Spent Fuel Storage Installation (ISFSI) pad on 6-23-09. This process was ongoing.
