EXECUTIVE

SUMMARY

During the year 2013, 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 261 environmental samples, 780 air samples, and 1134 thermo luminescent dosimeter (TLD) phosphors were collected over the course of the 2013 REMP monitoring period. Approximately 1694 radionuclide analyses were performed on the environmental and air samples.

This report contains results from the operational Radiological Environmental Monitoring Program for Diablo Canyon Power Plant compiled for the period January 1,2013 through December 31, 2013. This program was conducted in accordance with DCPP Program Directive CY2, "Radiological Monitoring and Controls Program," and RPI .IDI 1, "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 Carbon-14 (AC 14)

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

Drinking Water (DW) Ground Water (GW) Monitor Well (GW) Surface Water (SW)

Aquatic Vegetation (AV) Fish (FH) Mussels (IM) Sediment (SD)

In 2013, DCPP added routine voluntary supplemental vegetation sampling at Avila Valley Barn (station 7E 1). DCPP also added routine voluntary supplemental airborne Carbon-14 sampling within the southeast sector.

Diablo Canyon REMP collected environmental samples and shipped them to General Engineering Labs (GEL) located in Charleston, South Carolina. All 2013 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 pre-operational range. Beginning in June 2009, DCPP began loading of the onsite dry cask Independent Spent Fuel Storage Installation (ISFSI). ISFSI dry cask loading Campaign #4 occurred from August through September of 2013 within the site boundary. 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. The ISFSI had no significant impact on the REMP Environmental TLD station readings within the vicinity of the site boundary (approximately 800 yards from U-I Containment) and beyond.

On March 11'h, 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 Daiichi 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. The DCPP REMP periodically detected cesium (Cs-137) within market fish and cow meat due to deposition of Cs-137 from that event and the approximate 30 year half-life of Cs-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 four monitoring wells (stations OWl, DY1, GW1, 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. Cesium (Cs-137) was also detected in one shallow monitoring well (DYI). 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 rain concentrations of 2.4 to 25.4 pCi/Liter. This Fukushima Cs-137 was detected within one sample of monitoring well DYI at a concentration of 2.22 pCi/L in 2013 due to the approximate 30 year half-life of Cs-137. 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 2R14), four DCPP Unit Two (U-2) Steam Generators

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

• November 2009 (outage 2R1 5), one DCPP Unit Two (U-2) Reactor (Rx) Head

" October 2010 (outage 1R16), one DCPP Unit One (U-i) Rx Head

This OSGSF did not cause any changes to the ambient direct radiation levels within the DCPP environs during 2013. The OSGSF sumps were inspected quarterly by REMP personnel. These OSGSF sumps have remained empty and dry during 2013.

The results of the 2013 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 (PWR).

Unit I 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.

This AREOR summarizes the findings of the Radiological Environmental Monitoring Program (REMP) conducted by Diablo Canyon Power Plant. The remainder of this AREOR 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.

DCPP REMP sent replicate split samples of stations 7G1 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 split sampling program.

These split samples were independently analyzed by the CDPH-RHB.

Other pathways independently monitored by the CDPH-RIHB were quarterly direct radiation TLD stations (MTI, IAI, ICI, 4D1, 5F3, 5S1, 7D1, 7C1, 7F1, and 8S2) and weekly air sampling particulate and 1-131 (at stations 5F3 and 7D13).

The general public can access these CDPH-RHB split sampling data results via the internet at http://www.cdph.ca.gov/programs/Pages/RHB-RadReport.aspx.

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 (NUREG- 1301).

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.

Individual REMP sample isotopic results are shown in Appendix C of this report. Detected concentrations

( > MDC) of nuclear power plant related isotopes have been highlighted with yellow background and bold font for quick identification by the reader. Naturally occurring isotopes were not highlighted (including gross beta, Be-7, K-40, thorium, radium, radon, lead, etc).

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 "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 32 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 TLD badges were placed at each station and each badge contained 3 phosphors for a total of 9 phosphors at each station. The 9 phosphors were analyzed and averaged to provide a single station reading. The net exposure was reported over a standard 90 day 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 (ISFSI) 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 TLD badges were placed at each station and each badge contained 3 phosphors for a total of 9 phosphors at each station. The 9 phosphors were analyzed and averaged to provide a single station reading. The net exposure was reported over a standard 90 day 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: MT1, 0S2, ISI, 7D1, 8Sl and 8S2. Air particulate and radioiodine sampling was performed weekly at one control station: 5F1.

Constant flow air samplers (F&J model DF-1) 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, REMIP air samplers were converted to read out in units of cubic meters per hour in order to correlate with AREOR cubic meter reporting criteria. From August to December, the air samplers were set to a flow rate of 2.55 cubic meters per hour (which is equivalent to 1.5 standard cubic feet per minute). The air samplers were located approximately seven feet above the ground. The sample volumes were determined by F&J Corporation model DF-I 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 particulate filter and TEDA charcoal cartridge were collected. All necessary data regarding the air volume readings, flowrate, sampler time on / off, date of collection, and sampler station location were recorded and submitted to GEL along with the samples for isotopic analysis.

Approximately 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after sampling (to allow for radon and thoron daughter decay), the 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 Airborne Carbon-14 Air Carbon-14 sampling was performed weekly at station 8S 1.

General Engineering Labs (GEL) and DCPP REMP worked together to develop a method for sampling environmental airborne inorganic C-14. Inorganic C-14 (as CO2) is the primary exposure pathway to man via photosynthesis in plants (vegetation and meat). This method development began during the fourth quarter of 2012 and the LLD capability was improved into 2013. C-14 data from the 2012 experimental process development is also included in Appendix C for reference. A constant flow air sampler was used to draw air through a solid phase carbon sensitive sorbent cartridge. The air sampler was set at a flow rate of 1.0 standard liter per minute. The air sample cartridge head was located approximately seven feet above the ground. At the end of the weekly sampling

period, the filter cartridge was collected. All necessary data regarding the air volume reading, flowrate, sampler time on / off, date of collection, and sampler station location were recorded and submitted to GEL along with the sample for Carbon-14 analysis. At GEL, a suitable portion of the solid sorbent material was processed through a method utilizing wet oxidation to remove volatile CO 2 from the media in a closed distillation system. Once removed from the media, C-14 as carbon dioxide was sparged through a dilute acid solution for trapping any tritiated water present in the sample. After sparging through dilute acid, the CO 2 was trapped in a sorbing solution which was added to liquid scintillation cocktail and finally counted in a liquid scintillation counter. It should be noted that C-14 results in Appendix C are reported in uCi/cubic meter. This method met the following specifications:

" Validated to retain 99.9% of inorganic C-14 in air

• Validated at collection rates of approximately 1.0 liter per minute

• Validated for total collection capacity over a I week sampling interval

• Accurate analysis of C-14 over a wide range of concentrations

• Methodology free from interference by other radionuclides

" Detection limits of approximately I pCi per cubic meter 2.3.4 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 1A2), and from the DCPP drinking water system (station DWI). Drinking water was also collected from a control station located at 4325 South Higuera Street, Offsite Emergency Lab (station OEL) in San Luis Obispo.

Supplemental groundwater samples were collected from Water Well 02 (WW2)

and DCSF96-1 (8S3).

Supplemental on-site monitoring well samples were collected from french drain systems labeled Observation Well 01 (OWl), Observation Well 02 (OW2), and Drywell 115 (DY 1). 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 as part of the industry Groundwater Protection Initiative (GPI). Isotopic sampling of these wells was initiated in 2012. These two new onsite wells were downgradient of the power block and located along the western side of the power block. These two new monitoring wells were labeled Groundwater 1 (GWI) 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.

2.3.5 Marine Biological, Beach Sand, and Ocean Sediment The REMP required sampling of rockfish (genus Sebastes), perch (family Embiotocidae), mussels (genus 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-2F 1).

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

2.3.6 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 5 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 IS 1) sectors.

Additional representative samples of food crops (in season) were collected monthly from supplemental stations: Cal Poly Farm (5F2), Kawaoka Farm in Arroyo Grande (7G 1), Mello Farm (7C 1) along the DCPP site access road, and quarterly gardens (3C1, 6C1, and 7El).

The samples at 5F2, 7G1, 7C1, 3C1, and 7El were collected by DCPP personnel and sealed immediately in plastic bags. The quarterly garden sample at 6C1 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).

2.3.7 Milk There were no animals within the 5 mile 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 (5F2) which was approximately 13 miles from DCPP.

Two 1-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.

2.3.8 Meat A rancher routinely grazed (free range, grass fed) cattle, goats, and sheep within three miles of the site boundary between the northwest to east sectors (clockwise). 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, this meat sampling was included in the REMP.

REMP personnel obtained commercially packaged meat samples of each species directly from the land owner. Gamma spec and total strontium 89/90 analyses were performed on the meat.

Control station free range, grass fed meat sampling was conducted of ranches outside the influence of DCPP. At the beginning of 2013, this meat was sampled from Hearst Ranch meat which is located approximately 37 miles north of the DCPP site. This REMP station code was HCM (Hearst Cow Meat) and provided a control location far from the site. During the fourth quarter of 2013, local grocery stores discontinued the sale of Hearst Ranch meat due to drought conditions in San Luis Obispo County. These grocery stores switched suppliers to Sun Fed Ranch which raises cattle in the foothills of Sacramento Valley and the rangeland of the Klamath Basin between Mt Shasta and Crater Lake. Sun Fed Ranch beef is free range, grass fed beef. The REMP control station HCM will remain as designated with the understanding that HCM represents a control beef station and not a specific ranch location. REMP personnel purchased HCM 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 could not obtain deer meat samples from these property owners (voluntary participation) in 2013. Gamma spec and strontium analyses were performed on the deer meat if provided.

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

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

3. Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 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 I11) 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.

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

LLD = 4.66Sb E x V x 2.22 x Y x exp(-4t)

Where:

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

Sb = the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)

E = the counting efficiency (as counts per transformation)

V = the sample size (in units of mass or volume) 2.22 = the number of transformations per minute per pico-curie Y = the fractional radiochemical yield (when applicable)

X = 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 adetection 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 of E, V, Y and t should be used in the calculation. It should be recognized that the LLD is defined as a-priori (before the fact) limit representing the capability of a measurement system and not as a-posteriori (after the fact) limit for a particular measurement.

3.0 RADIOLOGICAL DATA-

SUMMARY

OF TABLES This section summarizes the analytical results of the environmental samples 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 (NUREG-130 1). 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 range of results for locations. The seventh column contains the number of 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 radionuclide/ media type, the range, and the number of samples that were considered to have detectable activity of all the samples counted:

• The mean value consisted of the average of detectable concentrations

• The lowest and highest detected concentration values were listed as the range

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

The radionuclides reported in this section represent those that:

" had an LLD requirement in Table 2.3, 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-108m, Ag-110m, Ba-140, Be-7, Bi-212, Bi-214, Ce-141, Ce-144, Co-57, Co-58, Co-60, Cr-51, Cs-134, Cs-137, Fe-59, 1-131, K-40, La-140, Mn-54, Nb-95, Pb-210, Pb-212, Pb-214, Ra-224, Ra-226, Ru-103, Ru-106, Sb-124, Sb-125, Th-234, TI-208, Zn-65, and Zr-95.

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

4.0 ANALYSIS OF ENVIRONMENTAL RESULTS 4.1 REMP SAMPLING VARIANCE / DEVIATIONS The DCPP Radiological Environmental Monitoring Program (REMP) 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/deviations with sampling and describes some of the supplemental sampling conducted during the year.

4.1.1 DIRECT RADIATION There were no abnormal effects to the 2013 environmental TLD results.

REMP environmental TLD station 2F2 (Morro Bay Power Plant) was reinitiated on 8/28/13.

Station 2F2 was originally part of the DCPP REMP since the 1980's. In 2001, PG&E faced deregulation bankruptcy proceedings and a Plan of Reorganization (POR). During that POR, Morro Bay Power Plant was sold to another electric energy company (Duke Energy). The 212 TLD station was removed from that location in 2001 due to the sale of the PG&E property. In 2013, DCPP REMP retained permission from the current Morro Bay Power Plant site owner (Dynegy) to reinstall the 2F2 TLD station. Ongoing environmental TLD monitoring at station 2F2 began on 8/28/13.

ISFSI projects conducted dry cask loading campaign #4 at ISFSI from August to October of 2013. This dry cask loading campaign affected some of the ISFSI TLD (IS-I through IS-8) measured exposures due to proximity of transport casks during ISFSI placement operations.

4.1.2 AIRBORNE RADIOACTIVITY The 2013 mean percent availability for all on-site and off-site air samplers was 99.6 percent.

In other words, all air samplers were up and running 99.6 percent of the time. Less than 0.4 percent of run time could be attributed to equipment problems, filter exchange, or calibration processes. Specific 2013 air sampling run time deviations were as follows:

• 163 hours0.00189 days <br />0.0453 hours <br />2.695106e-4 weeks <br />6.20215e-5 months <br /> of lost run time occurred at station IS1 during the week of 3/6/13 due to technician human error of not restarting the air sampling pump after filter exchange

Actual 2013 percent availabilities for each station were as follows:

0S2 = 99.8 %

1S1 = 98.0%

5F1 = 100%

7D1 = 99.9%

8S1= 99.8%

Airborne Carbon-14 supplemental sampling was performed weekly at station 8S 1 (SE Sector).

General Engineering Labs (GEL) and DCPP REMP worked together to develop a method for sampling inorganic environmental airborne C-14 (as CO 2 ). This method development began during the fourth quarter of 2012 and the process LLD capability was improved throughout 2013.

C-14 data from the 2012 experimental process development is also included in Appendix C for reference. It should be noted that C-14 lab data is reported in units of uCi/m 3 (not pCi/m 3) within Appendix C.

4.1.3 MARINE SAMPLES All 2013 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 2013 terrestrial samples were collected as scheduled (including allowable variation) with the following exceptions:

Blanchard Sheep Meat (BSM) and Blanchard Goat Meat (BGM) were not available and were not provided by the rancher during the first quarter of 2013. These animals were not slaughtered. These samples were supplemental.

4.1.5 OCEAN SURFACE WATER, DRINKING WATER, AND GROUNDWATER All 2013 water samples were collected as scheduled (including allowable variation) with the following exceptions:

• Observation Well 02 (OW2) was dry during all four quarters of 2013. No OW2 monitoring well water samples could be obtained in 2013.

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

Replicate samples were taken from:

• WW2 - Groundwater (2/7/13)

• 7C2 - Seawater (3/11/13) 0 WW2 - Groundwater (6/26/13) 0 5F2 - Vegetation (9/3/13) 0 7G1 - Vegetation (12/16/13)

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 2013.

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 enviromnental concentrations that relate to the ALARA design dose objectives of 10 CFR 50, Appendix 1.

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 2013 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 32 locations surrounding DCPP using Panasonic UD-814 thermo-luminescent dosimeters (TLDs). These 32 locations are made up of 29 indicator stations & 3 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 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. Technically, these TLDs read out in units of milli-roentgen. Because gamma and beta radiation have quality factors of 1, the environmental TLD unit of reporting was converted to milli-rem for consistency of unit reporting.

The unrestricted area surrounding DCPP was sparsely inhabited out to five miles from the site (ref 2013 Land Use Census in Section 8).

The ambient direct radiation levels within the DCPP plant site boundary (approximately 800 meter radius from U-1 CTMT structure) were elevated at some locations (IS-I thru IS-8) due to dry cask used fuel storage and an ISFSI loading campaign. ISFSI projects conducted the 2013 dry cask loading campaign at ISFSI from August to October. 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: OSI, 0S2, WN1, 1S1, 2S1, 3S1, 4S1, 5S1, 5S3, 6S1, 7S1, 8S1, 8S2, 9S1, MTl, and IS]. 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 OS , 0S2, OB 1). 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 (2F2, 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 low/high ranges from 1987 to 2012 for comparison of the 2013 data.

No adverse trends were noted in 2013 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 ISFSI stations 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 dry cask 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 dry cask canisters.

• In May 2010, DCPP began the second ISFSI loading of spent fuel dry cask canisters.

• A third ISFSI loading campaign occurred during the first quarter of 2012 and ended on 3/17/2012.

• A fourth ISFSI loading campaign occurred from August to October of 2013.

The ambient direct radiation levels within the DCPP plant site boundary and directly adjacent to the ISFSI pad 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 (10CFR20.1301) were conservatively met. No adverse trends were noted at the DCPP inner ring stations due to ISFSI for 2013 as indicated by the previous page 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.

The following page contains a picture of the ISFSI pad along with a trend graph of ISFSI pad TLD results (IS-I through IS-8). ISFSI pad TLD stations IS-I through IS-8 were located adjacent to the ISFSI pad fencing (see map in Figure 2.2 of this report).

4.4.2 Airborne Air particulate and radioiodine samples were collected weekly from six indicator stations (MTI, 0S2, 1S1, 7D1, 8S1, and 8S2) in the DCPP environs and one control station (5F1). A total of 364 air particulate filters and 364 iodine cartridges were collected and analyzed 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 7.1 E-3 to I.2E-1 pCi/m 3. The gross beta activities detected at the air sampling stations were tabulated in Appendix A.

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 of 364 normal REMP weekly charcoal cartridges were analyzed for 1-131.

1-131 was not detected in 2013.

Appendix A summarizes overall REMP air sampling results.

Appendix C contains individual air sampling station data results.

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 89/90, Iron-55, and Nickle-63.

No plant related radionuclides were detected in any of the 2013 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 gammna emitters, gross beta, tritium, total strontium 89/90, Iron-55, and Nickle-63.

No DCPP related radionuclides were detected in any of the 2013 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 (1A2).

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 first quarter of 2013 due to rainwater washout of gaseous tritium exiting the plant vent system (via an approved discharge path).

Stations 5S2, WN2, and IA2 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 Drywell 115 (DY1).

Observation Well 02 (OW2) was not sampled in 2013 due to no water present in the well during the entire 2013 timeframe. There has been an ongoing seasonal drought in San Luis Obispo County which contributed to this well being dry.

Monitoring wells OWl and DY1 contained low levels of tritium throughout 2013 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 one sample of the DY1 monitoring well due to rainwater washout of Fukushima isotopes (Cs-137) during March of 2011 (ref 2011 DCPP AREOR). This 2011 Fukushima Cs-137 deposition and 30 year half-life was eventually detected in this well. The 2013 DY1 Cs-137 concentration 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 GW 1 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 of 2012.

Tritium was detected in one quarterly sample of GWl monitoring well during 2013 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). Market fish samples were locally caught fish.

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 of market fish (station 2F1 and 7D3) most likely due to rainwater washout of Fukushima Cs-137 isotopes during March of 2011 (ref 2011 DCPP AREOR). For reference, the March 2011 Central Coast rainwater Cs-137 concentrations ranged from 2.4 pCi/Liter to 25.4 pCi/Liter due to Fukushima event fallout. This 2011 Cs-137 deposition and 30 year half-life was eventually detected in fish.

As previously stated, another source of Cs-137 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 2013 fish concentrations were within this historical range. 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 2013.

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 2013.

Supplemental intertidal algae sampling was performed quarterly at REMP sample stations DCM and 7C2 (control). No DCPP related isotopes were detected in 2013.

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 2013.

4.4.5 Food Crops (Vegetation)

Samples of broad leaf vegetation were collected monthly (when available) from two indicator stations (7C1 and 7G1), and one control location (5F2). Samples were also collected quarterly from residence gardens at stations 3C 1 and 6C 1. The samples were analyzed for gamma emitting radionuclides and for Iodine-I 31 on edible portions.

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 5 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 ISI.

Supplemental samples of milk were collected monthly from Cal Poly Farm (station 5F2). The samples were analyzed for gamma emitting radionuclides, Iodine- 131, and total strontium 89/90.

Milk samples were collected monthly from station 5F2 regardless of the availability of milk stations within 5 miles of the plant.

No DCPP related radionuclides were detected in station 5F2 milk samples during 2013.

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 2013. These samples were Blanchard cow meat (BCM), Blanchard sheep meat (BSM), and Blanchard goat meat (BGM).

An additional control meat sampling station was added to REMP to provide a meat sampling location outside the influence of DCPP. This additional 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 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 one of these 2013 meat samples due to the Fukushima Japan nuclear accidents. This detection occurred in one of the HCM samples in October. The 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 (ref 2011 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"h, 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 (ref 2011 DCPP AREOR). Fukushima related isotopes were first detected by the DCPP REMP beginning on March 17th, 2011. Airborne isotopic concentrations were detected from March 17'h thru April 20th of 2011. Various concentrations of 1-131, 1-132, Te-132, Cs-134, and Cs-137 were identified as Fukushima fallout along the Central Coast in March-April 2011. Due to the relatively short half-life of the previously mentioned isotopes; they are no longer detected in 2013 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 (ref 2011 DCPP AREOR).

• Additional 201 lair sampling at stations 0S2, 5F1, 7D1, and 8S1. 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 2011 DCPP AREOR)

• Additional 2011 milk and vegetation sampling was conducted at station 5F2 (ref 2011 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 ATAS) to establish additional control vegetation samples (ref 2011 DCPP AREOR).

• Additional 2011 thru 2013 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 (Ift by 3ft) were placed at 0S2 and 5F1 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 2011 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 but were attributed to the Fukushima event as the source.

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 2013 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 2013 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 of DCPP operation (e.g. 1-131, 1-132, Te-132, Cs-134). '

3. The 2013 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 2013 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 2013 due to it's half-life of approximately 30 years.

5.0 GROUND WATER MONITORING Diablo Canyon is committed to improving management of situations involving inadvertent radiological releases that get into onsite groundwater. 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 both discharge into the Pacific Ocean.

5.1 NEI 07-07 GROUNDWATER PROTECTION INITIATIVE - 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 2013 Annual Radiological Environmental Operating Report (AREOR) as follows:

Observation Well 01 (OWl), Observation Well 02 (OW2), Drywell 115 (DYI), DCSF96-1 (8S3),

Water Well 02 (WW2), Groundwater Well I (GWI), Groundwater Well 2 (GW2), and Diablo Creek Outlet (WN2) were used for Groundwater Protection Initiative (GPI) data reporting and were described in 2013 DCPP AREOR Table 2.1.

A summary of the 2013 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 (GPI) and the REMP. Concentrations of tritium were detected in two 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 DYI). 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.

DYl 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 dry throughout 2013. An ongoing seasonal extreme drought throughout San Luis Obispo County contributed to this well not containing any water in 2013.

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 2013 were as follows:

• OWl - Observation Well 01 ( 1,280 to 1,330 pCi/L ) 4 of 4 samples collected for tritium analysis.

" OW2 - Observation Well 02 ; no samples collected

" DYI - Drywell 115 ( 8,710 to 13,700 pCi/L ) 4 of 4 samples collected for tritium analysis.

• Cs-137 was detected in I of 4 DY1 samples but was attributed to 2011 Fukushima fall-out.

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

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

Groundwater Well 1 (GWI) 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 GW1/GW2 monitoring wells for 2013 were as follows:

GW1 - Groundwater Well 1 ( 316 pCi/L ) I 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 discharge route.

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

No other DCPP related isotopes were detected in GW1 or GW2.

Monitoring Well 8S3 was sampled quarterly in 2013.

Tritium was detected once out of four samples (314 pCi/L) 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.

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 2R14), four DCPP Unit Two (U-2) Steam Generators 0 2/14/09 (outage 1R15), four DCPP Unit One (U-l) Steam Generators

• 11/6/09 (outage 2R15), one DCPP Unit Two (U-2) Reactor (Rx) Head

• 10/23/10 (outage 1R16), one DCPP Unit One (U-l) Rx Head As of 10/23/10, 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 2013 by REMP personnel.

No water was found in any OSGSF sumps during. 2013 inspections.

1. Introduction GEL Laboratories, LLC (GEL) is a privately owned environmental laboratory dedicated to providing personalized client services of the highest quality. GEL was established as an analytical testing laboratory in 1981. Now a full service lab, our analytical divisions use state of the art equipment and methods to provide a comprehensive array of organic, inorganic, and radiochernical analyses to meet the needs of our clients.

At GEL, quality is emphasized at every level of personnel throughout the company.

Management's ongoing commitment to good professional practice and to the quality of our testing services to our customers is demonstrated by their dedication of personnel and resources to develop, implement, assess, and improve our technical and management operations.

The purpose of GEL's quality assurance program is to establish policies, procedures, and processes to meet or exceed the expectations of our clients. To achieve this, all personnel that support these services to our clients are introduced to the program and policies during their initial orientation, and annually thereafter during company-wide training sessions.

GEL's primary goals are to ensure that all measurement data generated are scientifically and legally defensible, of known and acceptable quality per the data quality objectives (DQOs), and thoroughly documented to provide sound support for environmental decisions. In addition, GEL continues to ensure compliance with all contractual requirements, environmental standards, and regulations established by local, state and federal authorities.

GEL administers the QA program in accordance with the Quality Assurance Plan, GL-QS-B-001.

Our Quality Systems include all quality assurance (QA) policies and quality control (QC) procedures necessary to plan, implement, and assess the work we perform. GEL's QA Program establishes a quality management system (QMS) that governs all of the activities of our organization.

This report entails the quality assurance program for the proficiency testing and environmental monitoring aspects of GEL for 2013. GEL's QA Program is designed to monitor the quality of analytical processing associated with environmental, radiobioassay, effluent (10 CFR Part 50),

and waste (10 CFR Part 61) sample analysis.

This report covers the category of Radiological Environmental Monitoring Program (REMP) and includes:

• Intra-laboratory QC results analyzed during 2013.

• Inter-laboratory QC results analyzed during 2013 where known values were available.

Laboratories LLC P.O. Box 30712, Charleston, SC 29417 2013 ANNUAL QUALITY ASSURANCE REPORT Page 6 of 58

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 Utah/Primary NELAP), gamma emitters, Gross Alpha/Beta, Iodine-131, naturally occurring radioactive isotopes, Strontium-89/90, and Tritium.

MLaboratories LLC P.O. Box 30712, Charleston, SC 29417 2013 ANNUAL QUALITY ASSURANCE REPORT Page 7 of 58

" 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. 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 may or 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.

• NELAC, National Environmental Laboratory Accreditation Program

• DOECAP, U.S. Department of Energy Consolidated Audit Program

• DOELAP, U.S. Department of Energy Laboratory Accreditation Program

• DOE QSAS, U.S. Department of Energy, Quality Systems for Analytical Services

• ISO/IEC 17025:2005

• A2LA, American Association for Laboratory Accreditation

• DOD ELAP, US Department of Defense Environmental Accreditation Program

• NUPIC, Nuclear Procurement Issues Committee

• South Carolina Department of Heath and Environmental Control (SC DHEC)

The annual radiochemistry laboratory internal audit (13-RAD-001) was conducted in August 2013. Three (3) findings, two (2) observations, and one (1) recommendations resulted from this

MR Laboratories LLC P.O. Box 30712, Charleston, SC 29417 2013 ANNUAL QUALITY ASSURANCE REPORT Page 8 of 58 assessment. By October, 2013, each finding was closed and appropriate laboratory staff addressed each observation and recommendation.

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 (i.e., 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 any one 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 AlphaLIMS. 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 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

MLaboratories LLC P.O. Box 30712, Charleston, SC 29417 2013 ANNUAL QUALITY ASSURANCE REPORT Page 9 of 58 radiochemical analyses is 75 - 125%. 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 (%) = (observed concentration)

• 100 %

(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 (DUP or LCSD) 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 (RPD). The RPD must be 20 percent or less, if both samples are greater than 5 times the MDC. If both results are less than 5 times MDC, then the RPD must be equal to or less than 100%. If one result is above the MDC and the other is below the MDC, then the RPD can be calculated using the MDC for the result of the one below the MDC. The RPD must be 100% or less. In the situation where both results are above the MDC but one result is greater than 5 times the MDC and the other is less than 5 times the MDC, the RPD must be less than or equal to 20%. If both results are below MDC, then the limits on % RPE) are not applicable.

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

8. Summary of Participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program Eckert & Ziegler Analytics provided samples for eighty-nine (89) individual environmental analyses. The accuracy of each result reported to Eckert & Ziegler Analytics, Inc. is measured by the ratio of GEL's result to the known value. All results fell within GEL's acceptance criteria (100%).

9. Summary of Participation in the MAPEP Monitoring Program MAPEP Series 27, 28 and 29 were analyzed by the laboratory. Of the one hundred thirty-eight (138) analyses, 96% (133 out of 138) of all results fell within the PT provider's acceptance criteria. Five analytical failures occurred: Uranium-238/235 and Total Uranium in vegetation by ICP/MS, and Uranium-234/233, and Urabuyn-238 by Alpha Spectroscopy.

For the corrective actions associated with MAPEP Series 28, refer to CARR130513-789 which is detailed in Table 8.

10. Summary of Participation in the ERA MRaD PT Program The ERA MRad program provided samples (MRAD-18 and MRAD-19) for one hundred fifty (150) individual environmental analyses. One hundred forty-five (145) of the 150 analyses fell within the PT provider's acceptance criteria (97%). Five analytical failures occurred: Cesium-134, Cesium-137 and Zinc-65 in soil, and Uranium-234 and Total Uranium in vegetation.

For the corrective actions associated with MRAD-18 and MRAD-19, refer to CARR130522-791 and CARR131205-845 which are detailed in Table 8.

11. Summary of Participation in the ERA PT Program The ERA program provided samples (RAD-92 and RAD-94) for forty-six (46) individual environmental analyses. Of the 44 analyses, 93% (43 out of 44) of all results fell within the PT provider's acceptance criteria. Two analytical failures occurred: Gross Alpha and Strontium-89 in water.

For the corrective actions associated with RAD-92 refer to corrective actions CARR130826-810 (Table 8).

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

Laboratories LLC P.O. Box 30712, Charleston, SC 29417 2013 ANNUAL QUALITY ASSURANCE REPORT Page 11 of 58 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 2013. It has been determined that causes of the failures did not impact any data reported to our clients.

CORRECTIVE ACTION ID#

& DISPOSITION PE FAILURE CARR130513-789 Root Cause Analysis of MAPEP-13-RdV28 Uranium-234/233, Uranium-235, Uranium-238 and Total ISO Documentation of PT Failures in Uranium MAPEP-1 3-RdV28 for Uranium in Vegetation by ICP/MS and Alpha Following reviews of our process and data and conversations Spec with personnel from the affected laboratories, it was determined that all failures were due to an analyst error during sample preparation. Glass instead of Teflon beakers were used during the sample digestion which contained Hydrofluoric (HF) acid. Per Standard Operating Procedure (

SOP) GL-RAD-A-015 section 11.2.4, the sample should have been transferred to a Teflon beaker. In this instance, this step was omitted. The digestion was performed in glass beakers so trace amounts of Uranium were leached from the glass into the sample, resulting in high bias in the results. Normal procedure dictates that glass is not used when using HF in the digestion process due to the presence of natural Uranium in the glassware.

In order to prove that this was an isolated incident and that our overall process is in control a series of digestions were performed in the glass beakers to confirm our conclusion.

• HCL /HNO 3 only digestion - Uranium was not detected.

• HCL, HNO 3 , and HF digestion - Enough Uranium activity was detected to account for the high bias (as many as 70 counts in a 16 hour1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> and 40 minute count).

• HF only digestion - Results similar to HCL, HNO 3 , and HF were observed A second PT was successfully analyzed for this matrix.

CARR130522-791 Following a review of our processes, the data and conversations with personnel from the affected laboratories, it ISO Documentation of PT Failures in was determined that our normal procedure for preparing soil

-MRAD-1 8 for Cesium-1 34, Cesium- samples is not sufficient for this soil matrix. Per the Standard 137 and Zinc-65 in Soil Operating Procedure (SOP) GL-RAD-A-021, the sample was

Laboratories LLC P.O. Box 30712, Charleston, SC 29417 2013 ANNUAL QUALITY ASSURANCE REPORT Page 55 of 58 dried, homogenized, and passed through a 28 mesh sieve.

However, approximately 20-30% of the sample consists of particles greater than the 28 mesh sieve size. These larger particles were not affected by our normal homogenization process. In accordance with the SOP, the larger particles were removed prior to preparing the container for gamma counting.

Upon receipt of the graded report, the following steps were taken to prove that this was an isolated incident and that our overall process is in control.

1. A recount of the initially prepared sample performed and confirmed the originally reported results.

2. A new container was then prepared from the original sample but omitting the preparation step and counted.

This produced acceptable results.

3. A second sample was prepared per the SOP; however, only a portion of the sample was removed during the sieving steps. This sample produced similar high biased results.

An aliquot of the sample was then pulverized prior to gamma counting. This approach also produced acceptable results.

Permanent Corrective/Preventive Actions or Improvements:

In the future, these samples will be pulverized to ensure that all the material passes through the 28 mesh sieve; thus, eliminating the need to remove any of the original sample. A comment has been added to the set-up for the solid matrix.

A second PT was successfully analyzed for this matrix.

The following steps were taken to prove that this high bias was an isolated occurrence and that our overall process is within control.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 110%. While the recovery is slightly elevated, it is well within the 80%-120% acceptance range.

2. Laboratory control data were also reviewed for trends. None were noted.

3. The instrument calibrations were reviewed for positive biases that could have attributed to this failure. None were noted.

4. Two sample duplicates were also prepared and counted along with the reported result. Both results fell within the method's acceptance range for duplicate. One of the results also fell within the acceptance range of the study.

5. The original sample was also recounted and the results fell within the acceptance range.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 98.1%.

2. Laboratory control data were also reviewed for trends. None were noted.

3. The instrument calibrations were reviewed for positive biases that could have attributed to this failure. None were noted.

4. Sample duplicates were also prepared and counted along with the reported result. Duplicate results fell within the acceptance range of the study.

EPA 905.0 After a review of the data, an apparent reason for this discrepancy could not be determined. The following steps were taken to prove that this hiqh bias was an isolated

MLaboratories LLC P.O. Box 30712, Charleston, SC 29417 2013 ANNUAL QUALITY ASSURANCE REPORT Page 57 of 58 occurrence and that our overall process is within control.

1. The batch quality control samples were reviewed and found to be compliant. The LCS recovered at 102%.

2. Laboratory control data were also reviewed for trends. None was noted.

3. The instrument calibrations were reviewed for positive biases that could have attributed to this failure. None were noted.

4. Sample duplicates were also prepared and counted along with the reported result. All results fell within the method's acceptance range for duplicates.

Permanent Corrective/Preventive Actions or Improvements:

Gross Alpha 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.

Strontium-89 (Sr-89)

LAB PBMS A-004 and EPA 905.0 To summarize our efforts (including the initial result), the laboratory had 3 analysts, two different methods, processed with 2 calibrations and two separate Y carriers used in the analysis of this sample and only one acceptable result for Sr-

89. All LCS results have met acceptance criteria. This leads the laboratory to conclude that there is possibly an error in the original make-up of the PT sample. The instructions list stable Sr and Y as being included but they are not at levels greater than are normally listed so we suspect that the make up of the sample was the cause. The laboratory will continue to monitor the recoveries from these two methods to ensure that there are no issues.

The reported result for U-234 was less than the 234 and Total Uranium in Vegetation MDA and had a elevated uncertainty. This high U-234 result also attributed to the high Total-U result.

Upon receipt of the graded report, the following steps were taken to prove that this was an isolated incident and that our overall process is in control.

• A recount, of the initially prepared sample performed and confirmed the originally reported results.

8.0 DCPP LAND USE CENSUS 2013 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 2013. The land use census is based on Nuclear Regulatory Commission (NRC) Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear Power Plants" and 10 CFR 50 Appendix I section IV. B. 3.

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

DCPP IDAP RP1 .ID1 1, "Environmental Radiological Monitoring Procedure", requires identification of the nearest milk animal, nearest residence, and the nearest broadleaf producing garden greater than 50 square meters (500 square feet) in each of the landward meteorological sectors within a distance of 8 kilometers (5 miles) of the plant. The land use census is conducted at least once per year during the growing season (between Feb 15 and Dec 1) for the Diablo Canyon environs.

The 2013 Land Use Census was conducted via a helicopter over-flight and landowner telephone interviews. The helicopter over-flight was conducted on October 3 1 st, 2013. The telephone interviews were conducted November 2 1 st through November 2 2 nd, 2013. Seven individual landowners or tenants were contacted.

Milk:

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

Residences:

The nearest residence, relative to all sectors, 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 8-kilometer (5-mile) radius of the plant, which were confirmed or appear to have been occupied in 2013. One additional residence was not occupied in 2013. 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 broadleaf vegetation. The READ garden (REMP 3C1) was approximately 1/4 acre and located in the NNE sector at 7.08 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 4.8 km and extended to 7.2 km (3 to 4.5 miles) from the plant. This commercial farm produced no broadleaf vegetation. The farm area was about 100 acres of land with rotational planting. Commercial crops consisted of about 100% 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 2013.

Additionally, BLANCHARD managed about 150 goats that were used for weed abatement in all landward sectors within the plant site-boundary. During 2013, 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 2013.

BLANCHARD also managed about 150 sheep outside the plant site-boundary in the NW and 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 2013.

The BLANCHARD's consumed about 75 pounds of these various meats during 2013.

"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 2013.

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 2013.

ANDRE had about 80 cattle outside the plant site-boundary in the ENE sector. About 80 calves were sold to mass market in 2013. ANDRE did not slaughter any cattle in 2013 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 2013. MELLO did not slaughter any cattle in 2013 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 2013.

The Point Buchon Trail was located at the north end of PG&E property and had about 18,000 visitors in 2013. The trail traversed about 3.5 miles of coastline from Coon Creek to Crowbar Canyon. The trail was open to the public for day hikes Thursday thru Monday from approximately 0700-1700. Two to three people from California Land Management occupied the trail head booth near Coon Creek 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 3,000 visitors in 2013. The trail was approximately 3.7 miles long and led from the Avila Beach DCPP Entrance Gate to the Point San Luis Lighthouse property. 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 2013.

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 2013.

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. An ISFSI loading campaign occurred in 2013.
