EXECUTIVE

SUMMARY

The Brunswick Steam Electric Plant (BSEP), Unit Nos. 1 and 2, is operated by Carolina Power &

Light Company, now doing business as Progress Energy Carolinas, Inc., under licenses granted by the Nuclear Regulatory Commission (NRC). BSEP Technical Specification 5.6.2 and the BSEP Offsite Dose Calculation Manual (ODCM) establish the requirements of the Radiological Environmental Monitoring Program (REMP). This report provides the results of the REMP from January 1, 2009 through December 31, 2009.

The REMP was established in 1973. Radiation and radioactivity in various environmental media have been monitored for more than 35 years, including monitoring in excess of a year prior to commencing operation. Monitoring is also provided for control locations which would not be impacted by operations of BSEP. Using the data from the control locations and the historical data collected prior to operation, analyses of data from locations which could potentially be impacted by the operations of BSEP were performed. Radiation levels show no measurable change from pre-operational radiation levels.

Monitoring results for environmental media are summarized as follows:

Air-monitoring results are similar or less than the concentrations of radioactivity from pre-operation monitoring. These observations are also consistent with past operational data.

" Milk was unavailable due to no milk (milch) animals (goat or cow) currently identified within the environs of the plant; therefore, no exposure pathway exists.

Terrestrial vegetation includes broadleaf vegetation from indicator and control locations.

Results indicate that Cobalt (Co)-60 and Cesium (Cs)- 137 activity was detected in indicator and control samples respectively, but no other gamma activity was detected in any sample except for K-40 (potassium-40) and other naturally occurring gamma activity.

Aquatic organism monitoring includes fish (free swimmers and bottom feeders),

invertebrates (shellfish (SH)), and Benthic organisms (organisms that live on the bottom of the ocean (BO)). Results indicated no detectable plant - related activity.

" Surface water results indicate that some surface water samples detect the presence of tritium, which is attributed to plant operations. Refer to the Interpretations and Conclusions Section / Surface Water and Figure 16.

" Shoreline Sediment results indicate that some shoreline sediment indicator and background samples detected the presence of Cs- 137 activity. No other gamma activity was detected in any sample (indicator or background) except for K-40 (potassium-40) and other naturally occurring gamma activity. Therefore, results indicated no detectable plant-related activity.

,

External radiation dose showed no measurable change from pre-operational data.

The continued operation of BSEP has not significantly contributed radiation or the presence of radioactivity in the environmental media monitored. The measured concentrations of radioactivity and radiation are well within applicable regulatory limits.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM PURPOSE AND REQUIREMENTS FOR THE RADIOLOGICAL MONITORING PROGRAM Although the operation of a nuclear generating station results in the raising of background radiation only a small amount, it is important to measure these emissions of radioactivity and radiation to assess their impact on the surrounding populations. The purpose of the REMP is to measure accumulation of radioactivity in the environments, to determine whether this radioactivity is the result of operations of BSEP and to assess the potential dose to the off-site population based on the cumulative measurements of radioactivity of plant origin. Radiological monitoring programs provide an additional verification of the containment and radiological controls of nuclear generating stations.

The REMP was established in 1973 and continues to collect samples and evaluate them.

Requirements are established for the radiological monitoring program as follows:

> Technical Specifications

> Off-Site Dose Calculation Manual (ODCM)

> Various procedures Additional guidance regarding the radiological monitoring program may be found in the following:

> NRC Regulatory Guide 1.109, "Calculation of Annual-Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I"

> NRC Regulatory Guide 4.13, "Performance, Testing, and Procedural Specifications for Thermoluminescence Dosimetry: Environmental Applications"

> NRC Regulatory Guide 4.15, "Quality Assurance for Radiological Monitoring Programs (Normal Operations) - Effluent Streams and the Environment" 3

General Site Description BSEP consists of two boiling water reactors with a design rating of 2923 megawatts thermal. Commercial production was initiated by Unit 2 on November 3, 1975 and by Unit 1 on March 18, 1977. BSEP is located in Brunswick County, North Carolina. The SC~p. F..

site is along state route 87 approximately 17 '

c..-h*U

.455Cn two and a half miles north of Southport and is displayed on the map of southeastern North Carolina (Figure 1).

The community of Boiling Spring Lakes is about three miles northwest of the site.

The towns of Caswell Beach and Oak Island are on a barrier island south of the Figure 1: Location of Brunswick Steami Electric Plant

.plant. The site is also approximately 16 miles south of Wilmington, North Carolina.

The Cape Fear River is east of the plant, and cooling water is drawn from the river through a canal. The cooling water is discharged to the Atlantic Ocean through a canal, pumping station, and piping. The discharge point is south of the town of Caswell Beach.

The plant site varies in elevation from sea level to 30 feet above mean sea level (MSL). It is surrounded by extensive marshes. The lower Cape Fear River is an important nursery area for shellfish, and other marine species.

The local economy supports significant recreational, industrial, agricultural, and government contributions. There is well-developed recreational use of the barrier islands south and east of the site. Fishing and boating are popular activities. Commercial fishing is also an important industry in the community. Agriculture utilizes some of the landwithin50 miles of the site; such as small truck farms, cattle, poultry, and row crops including corn, soybeans and tobacco.

Industrial activity includes the Archer-Daniels-Midland Chemical (ADM) Company, a manufacturer of citric acid, located one and a half miles southeast of the plant. In conjunction with the citric acid plant is a small electrical generating station operated by Primary Energy. This coal-fired station is composed of two units rated at 55 MWe each.

Transportation is a significant industry in the local economy, with the Port of Wilmington north of the site. The shipping channel is just east of the site in the Cape Fear River. Also, the Sunny Point Military Ocean Terminal (MOT) is located approximately three miles north of the plant site on the Cape Fear River.

RADIOLOGICAL MONITORING PROGRAM QUALITY ASSURANCE A required component of the REMP is the Quality Assurance Program. The standards for the quality assurance program are established in NRC Regulatory Guide (R.G.) 4.15, "Quality Assurance for Radiological Monitoring Programs." According to R.G. 4.15, the purpose of the quality assurance program is "(1) to identify deficiencies in the sampling and measurement processes to those responsible for these operations so that corrective action can be taken, and (2)ý to obtain some measure of confidence in the results of the monitoring programs in order to assure the regulatory agencies and the public that the results are valid." This provides the opportunity to implement corrective actions that address possible deficiencies. Examples of the activities of the quality assurance program include:

> regular review of sample collection and records,

> regular review of laboratory procedures and methods,

> participation in the Eckert & Ziegler Analytics Environmental Cross-Check Program, which provides an independent assessment of the quality of laboratory results,

> BSEP participates in the Eckert & Ziegler Analytics Radiochemistry Cross-Check Program,

> GEL Laboratories, LLC (GEL) participates in an Intercomparison sample program from Eckert & Ziegler Analytics of Atlanta, Environmental Resource Associates of Arvada, Colorado; and the Mixed Analyte Performance Evaluation Program (MAPEP), and

> the use of known concentrations of radioactivity in test samples by the laboratory to ensure consistent quality results on an ongoing basis.

RADIOLOGICAL MONITORING PROGRAM GENERAL DESCRIPTION Although the contribution to background radiation is small, Carolina Power & Light Company, now doing business as Progress Energy Carolinas, Inc. has established this program to measure the exposure pathways to man. An exposure pathway describes the source of the radiological exposure. The primary forms of potential radiological emissions from the plant are airborne and liquid discharge. The following pathways are monitored: external dose, ingestion of radioactive materials, and the inhalation of radioactive material. Specific methods and different environmental media are required to assess each pathway. Table 1 provides a list of the media used to assess each of these pathways.

Table -1 Media Used to Assess Exposure Pathways to Man Pathway of Exposure to Man Media Sampled External Dose Thermoluminescent Dosimetry (TLD)

Shoreline Sediment Ingestion Broadleaf Vegetation Fish and Invertebrates Surface Water Inhalation Air Samples (Particulate and Radioiodine)

Sampling Locations Sampling locations are chosen based upon meteorological factors, preoperational monitoring, and results of the land use surveys. A number of locations are selected as controls. Control stations are selected because they are very unlikely to be affected by operation of the plant.

Sample locations may be seen in Figures 2 thru 9. A description of each sample location may be found in Table 2.

SUMMARY

OF RADIOLOGICAL MONITORING PROGRAM This report presents the results of the Radiological Environmental Monitoring Program conducted during 2009 for BSEP. The program was conducted in accordance with the ODCM, and applicable procedures.

The 2009 Annual Radiological Environmental Operating Report (REOR) has been prepared and submitted in accordance with Technical Specification 5.6.2 and ODCM 7.4.1. The report applies to both BSEP Unit Nos. 1 and 2 (License Nos. DPR-71 and DPR-62, respectively).

A total of 1921 sample measurements were performed on 1818 collected samples from indicator and control locations from eight environmental media types during the year. No detectable radioactivity (or radioactivity that differed significantly from the-corresponding control) was observed in any of the 1700 measurements performed on the 1621 indicator location samples in 2009, except for Co-60 in broadleaf vegetation samples, and tritium in ground water and surface water samples. No gamma activity was detected in any of the ground water or surface water samples, except for K-40 and other naturally occurring gamma activity. All samples analyzed met the Lower Limit of Detection (LLD) requirements as established by ODCM Table 7.3.15-3.

The radiological environmental data indicates that BSEP operations in 2009 had no significant impact on the environment or public health and safety. No measurable radiation exposure is attributed to any off-site member of the public due to the operations of BSEP.

A statistical summary of all the data gathered in 2009 has been compiled in Table 3.

Comparison of the current data with preoperational (1973, 1974) information (Tables 4 and 5) indicates that air particulate filter gross beta activity and ambient gamma radiation levels were lower for gross beta and about the same for gamma in 2009.

FOOTNOTES TO TABLE 3

1. LLD is calculated based on 4.66 standard deviations above background using typical sample sizes and counting times. Due to counting statistics and varying volumes, occasionally lower LLDs are achieved. See Table 6.

2. Mean and range are based on detectable measurements only. The fractions of detectable measurements at specific locations are indicated in parentheses.

3. Missing samples are discussed in Missed Surveillances.

4. Summary of gamma analysis results in this report does not include the following naturally occurring isotopes since most environmental samples contained some or all of these: Be-7, K-40, T1-208, Pb-212, Bi-214, Pb-214, and Ra-226.

5. TLD dose is reported in milliroentgen (mR) per 90-day period (quarter) beginning in 1995.

This is the exposure standard used to compare data to the NRC.

6. The tritium LLD was approximately 2.50E+2 pCi/L. The LLD was lowered at the request of Carolina Power & Light Company, now doing business as Progress Energy Carolinas, Inc. in order to maintain comparable LLD values with the North Carolina Division of Radiation Protection (NCDRP) laboratory.

INTERPRETATIONS AND CONCLUSIONS Air Monitoring The average gross beta concentration measured in 298 air particulate (AP) samples collected at indicator stations during 2009 was 1.89E-2 picocuries per cubic meter (pCi/m3) and the average gross beta concentration measured in 52 AP samples collected at control stations during 2009 was 1.83E-2 pCi/m 3. The preoperational (1973-1974) average concentration was 8.2E-2 pCi/m 3, while the average activity in the recent past (2004-2008) was 1.86E-2 pCi/m 3 (Table 4). The airborne concentrations of gross beta activity in 2009 are indicative of natural background and do not indicate any abnormal activities originating from the nuclear operations at BSEP. Figures 10 through 15 depict the monthly variations of these values. In April of 2009, a new air sampler (APAC-206) was placed in service at the Brunswick Government Complex in Bolivia, N.C.;

which is approximately 11.3 miles NW of the plant site. This air sampler is not an ODCM required location. The air samplers operated for a total of greater than 99% availability for the 2009 year.

Gamma analyses of the composite air particulate filters indicated that all of the radionuclides indicative of plant effluents were at concentrations less than their respective LLDs. All radionuclides positively identified by the radionuclide analyses were typical of naturally occurring materials.

Analyses of 298 indicator and 52 control air cartridges (AC) for the collection of radioiodines indicated that concentrations of those radionuclides, and particularly 1-131, were less than the LLD. No 1-131 activity was identified in any indicator or control samples in 2009.

Milk No milk (milch) sampling locations are currently identified in BSEP environs; therefore, no sampling of this media was available.

Vezetation Food crops were not grown in the vicinity of the plant in 2009, and this media was represented by indigenous vegetation samples consisting primarily of wax myrtle leaves, along with cherry and sweetgum leaves. Fifty-four (54) samples were collected from indicator locations and 15 samples from the control location. No detectable activities relating to plant effluents were detected in this sampling media in 2009, except for three broadleaf (BL) wax myrtle samples sampled February 2, 2009 (BL-803), and May 1, 2009 (BL-801), which indicated Co-60 (cobalt-

60) activity (2.63E 7.57E-2 pCi/gram wet). Broadleaf- 803 (BL-803) was resampled on February 5, 2009, and the results did not indicate any Co-60 activity (NCR # 319178). However, BL - 801 was resampled on May 6, 2009, and indicated Co-60 activity of 2.3 1E-2 pCi/gram wet) 22

(NCR # 335156). There have been no subsequent environmental vegetation samples which indicated the presence of Co-60. Cesium (Cs)-137 (1.60E 1.78E-2 pCi/gram wet) activity was detected in two (wax myrtle broadleaf samples) out of fifteen control samples. No other gamma activity was detected in any sample, except for K-40 (potassium-40) and other naturally occurring gamma activity.

Fish and Invertebrates Fish (free swimmers and bottom feeders), invertebrate (SH), and benthic organism (BO) samples are collected semiannually from two locations: (1) near the Atlantic Ocean discharge pipe at Caswell Beach and (2) a control location in the Atlantic Ocean not influenced by plant operations and annually from three locations on Nancy's Creek (Figure 4). In all 15 samples (indicator and control), no detectable activities relating to plant effluents were detected in 2009. All radionuclides positively identified by the radionuclide analyses were naturally occurring nuclides.

The fish locations on Nancy's Creek sampled in 2009 were also analyzed for tritium, with all the tritium results being less than LLD.

Groundwater Groundwater is sampled semiannually and quarterly from 40 indicator sample sites. These samples are analyzed for gamma-emitting radionuclides (at least semiannually) and for tritium (at least quarterly). The analyses indicated that no detectable concentrations of gamma emitting radionuclides relating to plant effluents appeared in any of the indicator samples. Analyses indicated detectable concentrations of tritium in 185 out of 403 samples analyzed in 2009. No groundwater samples exceeded reportable concentrations, and there is no indication that the tritium is migrating beyond the Progress Energy owned property through the groundwater.

Shoreline Sediments Two shoreline sediments in 2009 were drawn from the beach area near the pumping station location at Caswell Beach. In both samples, all of the radionuclides indicative of plant effluents were determined to be less than the respective LLDs for gamma-emitting -radionuclides. Three shoreline sediments in 2009 were drawn from Nancy's Creek adjacent to WP-55 near the Storm Drain Stabilization Pond (SDSP), where all three indicator samples contained Cesium (Cs)-137 activity (1.44E 2.03E-1 pCi/gm dry). The samples were analyzed for Iron (Fe)-55, Strontium (Sr)-89, and Strontium (Sr)-90 by GEL, all were less than the respective LLDs. A Shoreline Sediment background sample was collected December 21, 2009 (19 miles N from the plant at Belville Park). The Shoreline Sediment background sample indicated the presence of Cs-137 activity (2.55E-2 pCi/gram - dry single value) along with other naturally occurring gamma activity.

23

Surface Water Surface water (SW) is sampled monthly from the intake and discharge canal and Nancy's Creek is sampled weekly. These samples are analyzed for gamma-emitting radionuclides and for tritium. Tritium analysis is performed weekly on the Nancy Creek samples. Sampling and compositing for gamma emitters is weekly and the gamma analysis is performed monthly on the samples composited weekly. The analyses indicated that no detectable concentrations of gamma emitting radionuclides relating to plant effluents appeared in any of the indicator and control samples. None of the control samples indicated the presence of tritium. However, forty-eight (48) out of 272 indicator samples indicated the presence of tritium in 2009. The predominate location(s) indicating tritium were at Nancy's Creek and the discharge canal indicator locations.

One (1) of the twelve samples from the historical discharge canal indicated the presence of tritium, while forty-seven (47) out of 260 samples from Nancy's Creek indicated the presence of tritium. The tritium activity detected in SW-401 (the discharge canal composite sample) had a single tritium concentration of 5.75E+2 pCi/L, which was expected due to plant operations at the time of sampling. The indicator samples from Nancy's Creek had a maximum concentration of 1.1 OE+3 pCi/L of tritium activity. The reporting limit for tritium in environmental samples is 30,000 pCi/L; therefore, the detected values are well below the reportable limit. Figure 16 depicts the observed tritium concentrations for SW-400 (control) and SW-401 -(indicator) in 2009.

External Radiation Exposure The environmental data on external radiation exposure for 2009 was essentially unchanged from 1989-2008 with an average exposure for all of 2009 indicator locations of 10.0 mR per quarter.

The average exposure observed over the preoperational period was 1.02 mR per week observed from the fourth quarter of 1972 through the second quarter of 1975. Table 5 provides a comparison of recent data with the preoperational and historical data...

The highest average exposure occurred at one TLD location at 619 miles WSW. The exposure was 12.0 mR per quarter. Figure 17 depicts average inner and outerring TLD data for each quarter of 2009. This depiction does not indicate a significant higher exposure rate for the inner versus the outer ring. This is interpreted as demonstrating that no discernible off-site exposure has occurred from plant operations.

However, this sample will still be counted and the data reported; whereas a "missed sample" will have no data reported. The air samplers operated for a total of greater than 99% availability for the 2009 year.

All AP and AC samples were available for counting in 2009.

Food Crops / Vegetation No food crops were grown in the vicinity of the plant in 2009; therefore, none were collected.

The media were represented by indigenous vegetation samples (broadleaf vegetation) consisting primarily of wax myrtle leaves, along with a few cherry and sweetgum leaves.

Thermoluminescent Dosimeters (TLDs)

One out of a possible 180 TLD samples was missing during 2009. The missing TLD occurred:

Fourth Quarter TLD # 8 was missing in the field due to the power pole it was stationed on being replaced, which resulted in the loss of the TLD. A new TLD and holder were installed on the-new power pole in the same location-(NCR #

374236).

ANALYTICAL PROCEDURES Gross Beta Gross beta radioactivity measurements are made utilizing a Tennelec Low-Background Alpha/Beta Counting System. The LLD for air particulates is approximately 5.0E-3 pCi/m3.

AP samples are mounted in two-inch stainless steel planchets and are typically counted directly for 50 minutes.

Tritium Liquid samples requiring tritium analysis are treated with a small amount of sodium hydroxide, potassium permanganate crystals, and then distilled. The distillate is mixed with a liquid scintillation cocktail and counted for the appropriate time to reach the desired LLD. The desired LLD was approximately 2.50E+2 pCi/L. This lower LLD was established to compare BSEP tritium LLDs and North Carolina Department of Radiation Protection's reportable concentrations, in the Split Sample Program's Annual Report. The fish samples requiring tritium analysis are analyzed by a vendor laboratory. The ground water samples and most of the surface water samples requiring tritium analysis are analyzed by the BSEP laboratory.

Iodine-131 Iodine- 131 airborne concentrations are analyzed by the intrinsic germanium (Ge) gamma spectrometry. systems. The cartridges are placed on the detector and each charcoal cartridge 3is typically counted individually for 2,500 seconds with an approximate LLD of 5i0E-2 pCi/m .

Gamma Spectrometry Gamma spectrum analysis utilizes intrinsic germanium detectors with thin aluminum windows housed in steel and lead shields. The analyzer system is the Canberra APEX Gamma Spectroscopy System. Table 6 summarizes LLD values derived from using the instrument with the worst sensitivity, typical sample volumes, typical count times, typical worst background count, and worst case on decay (from collection to counting).

AP filter quarterly composites are placed in a Petri dish and analyzed directly for a typical count time of 7,000 seconds.

Liquid samples are transferred to Marinelli beakers and analyzed by gamma counting. One-liter SW samples are gamma scanned directly in a 1-Liter Marinelli beaker for 60,000 seconds.

28

Shoreline sediments are dried, ground, weighed, and then analyzed in a Marinelli beaker for.a typical count time of 1,500 seconds.

Broadleaf vegetation is weighed wet and analyzed in a Marinelli beaker for a typical count time of 7,500 seconds.

Fish samples are prepared by stuffing small raw, edible portions of the fish in a one liter Marinelli beaker and edible portions of invertebrate organisms are cleanedand placed in a one liter Marinelli beaker for analysis for a typical count time of 1,800 seconds.

Thermoluminescent Dosimetry Each area monitoring station includes a TLD packet, which is a polyethylene bag containing three calcium sulfate phosphors contained in a Panasonic UD-814 badge. The TLD is light tight and the bag is weather-resistant.

Dosimeters are machine annealed before field placement. Following exposure in the field, each dosimeter is read utilizing a Panasonic TLD reader. This instrument integrates the light photons emitted from traps as the dosimeter is heated. Calibration is calculated using dosimeters irradiated to known doses for each set of dosimeters measured. Prior to the measurement of each dosimeter, the instrument is checked through use of an internal constant light source as a secondary standard. The exposure reported is corrected for exposure received in transit and during storage through the use of control dosimeters.

Interlaboratory Comparison Program, The Radiochemistry Laboratory at the Harris Energy & Environmental Center in New Hill, North Carolina, provides radioanalytical services for Progress Energy Carolinas, Inc.'s nuclear plant radiological environmental surveillance programs. In fulfillment of ODCM Operational Requirements, the laboratory is a participant in the Eckert,& Ziegler AnalyticsEnvironmental Cross-Check Programrand uses its performance in this program as a major determinant of the accuracy and precision of its analytical results. .

The Interlaboratory Comparison Program entails measurements on each instrument that is used to determine concentrations of radioactive material in the various media that are analyzed as part of the REMP. During 2009, 94 average analyses were completed on 18 samples representing seven major environmental media (i.e., water, milk, air filters, air filters composite, soil, air cartridges, and simulated vegetation). Data on the known activities, the uncertainties, and the ratios to the known for the 94 average analyses have been received from Eckert & Ziegler Analytics. The results were compared to the criteria established in the NRC Inspection Manual (Procedure ' .

84750) for Radioactive Waste Treatment, Effluent, and Environmental monitoring (see below results).

'29

All of the 94 average analyses were within the acceptance criteria. During 2009, the individual measurements were evaluated and results falling outside the acceptable ratio criteria will have an evaluation performed to identify any recommended remedial actions and to reduce anomalous errors (NCR # 334599, 360485, and 376364). Complete documentation of any evaluation will be available and provided to the NRC upon request.

Also, included at the end on the report in the Appendix is a summary of General Engineering Laboratories' (GEL's) Interlaboratory Comparison Program results for 2009. Delineated in the results are: the Sample Number or Study ID; Analysis quarter and year; sample media; specific radionuclide; its unit; its result; the known values supplied by the providers; GEL's ratio to the known value or acceptance criteria provided by the provider; evaluation criteria.

LAND USE CENSUS PURPOSE OF THE LAND USE CENSUS The land use census identifies the pathways (or routes) that radioactive material may reach the general populations near commercial nuclear generating stations. This is accomplished by completing studies each year that identify how the surrounding lands are used by the population.

A comprehensive census of the use of the land within a five-mile distance of the plant is completed during the growing season each year. This information is used for dose assessment and to identify changes to the stations sampled and the type of samples. These results ensure that the Radiological Environmental Monitoring Program (REMP) is based upon current data regarding human activity in the vicinity of the plant. Therefore, the purpose of the land use census is both to ensure the monitoring program is current as well as to provide data for the calculation of estimated radiation exposure.

The pathways that are evaluated are:

> Ingestion Pathway - Results from eating food crops that may have radioactive materials deposited on them from the atmosphere or contain radioactive materials from the soil.

Another pathway is through drinking milk from local cows or goats if these are present.

The grass used to feed these animals may have incorporated or had deposited on it radioactive materials that can be transferred to the milk.

> Direct Radiation Exposure Pathway - Results from deposition of radioactive materials on the ground or from passage of these radioactive materials in the air.

>' Inhalation Pathway - Results from breathing radioactive materials transported in the air.

36

Methodology The following must be identified within the five-mile radius of the plant for each of the 16 meteorological sectors (compass direction from which the winds may blow, for example NNE

[North North East]):

> The nearest resident

)> The nearest garden of greater than 500 square feet, producing broadleaf vegetation

) The nearest milk animal The following must also be identified (for elevated releases) within the three-mile radius of the plant for each of the 16 meteorological sectors:

> The location of all milk animals

> The location of all gardens of greater than 500 square feet, producing broadleaf vegetation The primary method is visual inspection from roadside within the five-mile radius, with the exception of the Sunny Point Military Ocean Terminal. This information may be supplemented with data from aerial photographs and a Global Positioning System (GPS) to determine distance and direction from the plant.

2009 Land Use Census Results The 2008 and 2009 results of the survey for the nearest resident, garden, milk and meat animals in each sector are compared in Table 7.

The resident portion of the census conducted in June of 2009 did not identify changes in the identity of the nearest resident from plant center from 2008. The garden portion of the census identified changes in the distances, locations, and existence of the nearest garden in seven sectors during the 2009 census.

The nearest garden location changed in the North (N) sector from a garden at 1.0 miles to no garden, the South (S) sector from 1.8 miles to 2.0 miles, the South Southwest-(SSW) sector from 1.9 miles to 2.0 miles, the Southwest (SW) sector from 3.0 miles to 1.6 miles, the West (W) sector from 1.0 mile to 0.9 miles, the Northwest (NW) sector from 4.9 miles to 1.0 mile, and the North Northwest (NNW) from 0.9 miles to 0.9 miles (different location). No milk animals-were located within 5 miles of the plant in 2009.

The 2009 Garden Census was conducted within 3 miles of BSEP and identifies all gardens of greater than 500 square feet that were found in the survey area. Results of the garden census are located in Table 8.

Results of the 2009 Land Use and Garden Census indicate stable use of land, confirming that current control locations are appropriate, and no changes are needed for dose assessment and environmental motoring.

-1843.056.8171F 843.766.1178 Www.gol.com 2009 INTERLABORATORY COMPARISON PROGRAM REPORT In accordance with US Nuclear Regulatory Commission requirements, GEL Laboratories, LLC (GEL) participates in an Interdaboratory Comparison Programs (ICP) that satisfies the requirements of both Regulatory Guide 4.15, Revision 1, "Quality Assurance for Radiological Monitoring Programs (Normal Operations) - Effluent Streams and the Environment", February 1979 and Regulatory Guide 4.15, Revision 2, "Quality Assurance for Radiological Monitoring Programs (Inception through Normal Operations to License Termination) - Effluent Streams and the Environment", July, 2007. Both guides indicate the ICP is to be conducted with the Environmental Protection Agency (EPA) Environmental Radioactivity Laboratory Intercomparison Studies (Cross-check) Program or an equivalent program, and the ICP should include all sample medium/radionuclide combinations that are offered by the EPA and included in the REMP.

Intefcomparison samples, were obtained from Eckert & Zeigler Analytics of Atlanta, Environmental Resource Associates of Arvada, Colorado and the Mixed Analyte Performance Evaluation Program (MAPEP). Each provider has a documented Quality Assurance (QA) program and the capability to prepare Quality Control (QC) materials traceable to the National Institute of.Standards andTechnology.

The ICP is a third party blind testing program which provides a means to ensure independent checks are performed on the accuracy and precision of the measurements of radioactive materials in environmental sample matrices. The providers supply the crosscheck samples to GEL. Upon receipt, the laboratory performs the analyses in a normal manner. The results are then reported to the provider for evaluation.

The samples offered by ICP providers and included in GEL's analyses are gamma isotopic analyses of an air filter, milk, water, soil and vegetation, Sr-89/90 in Milk and water and 1-131 in cartridges. The accuracy of each result reported to Analytics, Inc is measured by the ratio of GEL's result to the known value. Accuracy for all other results is based on statistically derived acceptance ranges calculated by the providers. An investigation is undertaken whenever the ratio or reported result fell outside of the acceptance range.

A summary of GEL's results is provided in the tables below for the required sample matrix types and isotopic distribution. Delineated in the table are: the Sample Number or Study ID; Analysis quarter and year; sample media; specific radionuclide; its unit; its result; the known values supplied by the providers; GEL's ratio to the known value or acceptance criteria provided by the provider; evaluation criteria.

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

The root cause of the Sr-90 failures was determined to be a batch quality control issue. The carrier yield for the second separation was greater than 100%. The elevated yield caused the Sr-90 result to be biased low. Even though the yield fell within its acceptance range, if problem solved 49

GEL Laboratories, LLC 2009 Interlaboratory Comparison Study February 2, 2010 Page 2 of 5 adjusted to reflect recoveries typically observed inthis procedure, the sample results would be within the acceptance range.

2009 BSEP Radiological Environmental Monitoring Analysis Report Comments 0 Efficiency values are not included for AC samples requiring radioiodine analysis (1-131), because gamma software does not report these values.

The Less than LLD (<LLD) represents that no activity was present, but lists the LLD values.

There are no 2 sigma error values reported when activity is <LLD.

Tritium samples that exhibit activity will not indicate LLD values for the following samples:

Groundwater samples (402 - 440 and 447)

Surface Water samples (494 - 499)
