EXECUTIVE

SUMMARY

The H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP) is operated by Carolina Power &

Light Company; also known as Progress Energy Carolinas, Inc.; under a license granted by the Nuclear Regulatory Commission (NRC). The HBRSEP Technical Specifications and the HBRSEP Off-Site Dose Calculation Manual establish the requirements of the Radiological Environmental Monitoring Program. This report provides the results of the Radiological Environmental Monitoring program from January 1, 2007 through December 31, 2007.

The Radiological Environmental Monitoring program was established in 1973. Radiation and radioactivity in various environmental media have been monitored for more than 30 years.

Monitoring is also provided for control locations that would not be impacted by operation of the HBRSEP. Using these control locations and data collected prior to operation allows comparison of data collected at locations near HBRSEP that could potentially be impacted by its operation. The pre-operational monitoring program began in December 1968.

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 monitoring has not been conducted due to the unavailability of milk samples in the area since July 17, 1998 when the dairy ceased operation. Broadleaf sampling is conducted, since no milk animals are located within five miles of the plant in any sector. Milk sampling will resume if a new sample location is identified.

Terrestrial vegetation includes broadleaf vegetation and food products. Results indicate detectable concentrations of Cs-137 in both the indicator and control locations for broadleaf vegetation. No other gamma activity was detected in any samples, except for K-40 and other naturally occurring gamma activity. Sampling of miscellaneous food products (non-leafy) in the vicinity of the site is conducted when leafy vegetables are not being grown.

Refer to the Interpretations and Conclusions Section / Food Products.

> Aquatic organism monitoring includes fish and aquatic vegetation. Results indicate detectable concentrations of Cs- 137 and K-40 in both indicator and control locations for fish, while results also indicate other naturally occurring nuclides in both indicator and control samples. The aquatic vegetation indicator samples indicated the presence of Co-58 activity. A new aquatic vegetation location was added to the monitoring program in August of 2007. Refer to the Interpretations and Conclusions Section / Aquatic Vegetation.

Surface water results indicate that the surface water from Lake Robinson shows the presence of tritium, which is attributed to plant operation. A new surface water location was added to the monitoring program in August of 2007.

1

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

Sediment monitoring includes both shoreline and bottom sediment. During 2007, bottom sediment results indicated the presence of Cs-137 and Co-60. No other gamma activity was detected in any sediment samples, except for naturally occurring gamma activity. A new bottom sediment location was added to the monitoring program in August of 2007.

The continued operation of HBRSEP has not significantly contributed radiation or the presence of radioactivity in the environmental media monitored. The measured concentrations of radioactivity 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 radiological monitoring program is to measure accumulation of radioactivity in the environment, to determine whether this radioactivity is the result of operation of the HBRSEP, and to assess the potential dose to the off-site population based on the cumulative measurements of radioactivity of plant origin. Radiological environmental monitoring programs provide an additional verification of the containment and radiological controls of nuclear generating stations.

The radiological monitoring program was established in 1973 and has continued to collect and analyze samples since that time.

Requirements are established for the radiological monitoring program in the Technical Specifications and the Off-Site Dose Calculation Manual (ODCM).

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

Lake Robinson is adjacent to the plant and is the source of cooling water. The lake was impounded during the construction of Robinson Unit No.1 (coal fired). The lake is fed by Black Creek and is approximately 2,250 acres in area. The plant intake is at the southern portion of the lake near the dam. The discharge is to a canal which conveys the cooling water to a point 4.2 miles north of the plant, where it returns to Lake Robinson.

The local economy supports primarily industrial and agricultural contributions. Fishing, boating, and swimming are popular activities on Lake Robinson and other nearby lakes. These activities contribute to the radiological pathways by consumption of fish and immersion related to swimming and boating. Consumption of milk and food products contributes to the ingestion pathway. No milk animals are located within five miles of the plant in any sector at this time, so broadleaf sampling is conducted to simulate the milk ingestion pathway.

RADIOLOGICAL MONITORING PROGRAM QUALITY ASSURANCE A required component of the environmental radiological monitoring program is the Quality Assurance Program. The standards for the Quality Assurance Program are established in the 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 to "(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) 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." NRC Regulatory Guide 4.15 B, Pg. 4.15-2. 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 an Environmental Interlaboratory Comparison Program, which provides an independent assessment of the quality of laboratory results.

> 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; also known 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 pathways monitored are 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.

Ingestion Broadleaf Vegetation Food Products Fish Ground Water Surface Water Inhalation Air Samples (Particulate & Radioiodine)

Sampling Locations Sampling locations are chosen based upon meteorological factors, pre-operational 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 and 3. A description of each sample location may be found in Table 2.

SUMMARY

OF RADIOLOGICAL MONITORING PROGRAM The Radiological Environmental Monitoring Program (REMP) was conducted in accordance with the HBRSEP Off-Site Dose Calculation Manual (ODCM) and approved procedures.

The purpose of the REMP is to measure accumulation of radioactivity in the environment, to determine whether this radioactivity is the result of the operation of the HBRSEP, Unit No. 2, and to assess the potential dose to the off-site population based on the cumulative measurements of radioactivity of plant origin. Approximately 1,409 samples were collected from indicator and control locations and 1,460 analyses and measurements were made during 2007. Detectable radioactivity resulting from plant operation was found in 28 out of 29 indicator samples of surface water (Table 4). Only the tritium activity in fish samples constituted a potential source of public exposure. Using the methodology of 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, Revision 1, dated October 1977," the greatest potential exposure to an individual of the public (being an adult) from the fish consumption of approximately 46 pounds (21 kg) of fish per year and assuming that tritium concentration is in equilibrium with the fish flesh is 0.004 millirem per year.

1. A statistical summary of all the data gathered in 2007 has been compiled in Table 3.

2. Radioactivity in environmental samples attributed to plant operations in 2007, for which there is a potential dose pathway to the public, is summarized in Table 4.

3. All detectable radionuclides in the environmental samples. for 2007 were less than reporting levels as defined in HBRSEP ODCM. Table 5 summarizes the reporting levels.

4. Environmental sampling and analyses performed during 2007 demonstrated that the HBRSEP, Unit No. 2 continues to operate with minimum impact on the environment and minimal dose to the general public.

FOOTNOTES TO TABLE 3

1. Lower Limit of Detection (LLD) is the smallest concentration of radioactive material in a sample that will yield a net count above system background that will be detected with 95 percent probability with only 5 percent probability of falsely concluding that a blank observation represents a "real" signal. Due to counting statistics and varying volumes, occasionally lower LLDs are achieved.

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. Three types of broadleaf vegetation samples are collected monthly when available from four locations for a possible total of 144 samples.

5. Bottom sediment and aquatic vegetation sampling are not required by plant Offsite Dose Calculation Manual (ODCM). Sampling and analysis is performed to monitor any radionuclide buildup in the lake.

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

7. In the past, the tritium LLD was lowered to 3.50E+2 pCi/L for samples that typically demonstrate activity less than the LLD (groundwater and surface water control). The LLD was lowered to be consistent with the LLD used by the state laboratory. Other samples that typically exhibit activity greater than the LLD have a tritium Lower Limit of Detection (LLD) of 1.OE+3 pCi/L.

INTERPRETATIONS AND CONCLUSIONS Air Sampling Air samples collected during 2007 had a mean gross beta activity of 2.37E-2 pCi/m 3 for the indicator stations versus an average concentration of 2.23E-2 pCi/m 3 for the control stations.

These data are essentially unchanged from 2006; they are consistent with pre-operational data obtained for the HBRSEP Unit No. 2 (1.40E- 1 pCi/ in 3), and reflect the occurrence of naturally occurring radionuclides of the region. The lower current value is primarily due to the reduction of worldwide fallout that was occurring during the pre-operational years. Figures 4 through 12 provide a graphic representation of the gross beta activity at the indicator locations compared to the control location for 2007. These figures confirm that the indicator stations show no significant increase over the control samples and hence no discernible impact from the plant operation is apparent in the data. Air samplers that experienced down time of greater than 30.

hours in a surveillance period are referred to as missed surveillances and discussions can be located in the Missed Surveillances Section of this report. The air samplers operated for a total of 99.6% availability for the 2007 year.

The quarterly composite gamma analyses for air particulate samples for all quarters revealed no radionuclides typical of plant effluents.

There was no Iodine-131 (1-131) detected in any of the 476 air cartridge (AC) samples from the indicator stations and 53 air cartridges from the control location in 2007.

Broadleaf Veuetation Broadleaf vegetation sampling is accomplished by collecting cherry, sassafras, and wax myrtle leaves in 2007. Three species of samples, when available, are collected monthly at four locations (one control and three indicator locations at the site boundary selected using historical meteorology with the highest calculated annual average ground level deposition). Broadleaf sampling is conducted since no milk animals are located within a radius of approximately five miles of the plant and is used to simulate dose to an individual via the milk pathway for compliance purposes.

20

During 2007, 17 of 48 samples taken from the indicator sites demonstrated detectable concentrations of Cs-137 for an average value of 4.14E-2 pCi/g (wet). The control samples had detectable concentrations of Cs-137 in 4 of 16 samples with a mean concentration of 3.25E-2 pCi/g (wet). Upon comparing these results, it is concluded that the indicator values reflect fallout Cs-137 contamination. Past sampling experience further supports this interpretation.

Fish Samples of free-swimming and bottom-feeding fish were taken from Lake Robinson and Prestwood Lake (the first downstream lake) and compared to similar fish from a control lake, which is unaffected by plant operation. During 2007, 3 out of 4 bottom-feeding fish and 4 out of 4 free-swimming fish (indicator sites) demonstrated detectable concentrations of Cs-137 for an average value of 3.39E-2 pCi/g (wet) and 4.62E-2 pCi/g (wet), respectively. The control samples had detectable concentrations of Cs-137 for 2 out of 2 bottom-feeding fish and 2 out of 2 free-swimming fish for an average concentration of 3.83E-2 pCi/g (wet) and 6.74E-2 pCi/g (wet), respectively. Upon comparing these results, it is concluded that the indicator values reflect fallout Cs-137 contamination. Past sampling experience further supports this interpretation.

Ground Water No gamma activity associated with plant operations or tritium activity was detected in the ten samples of ground water collected in 2007, which is consistent with the observations in previous years.

Milk Broadleaf sampling is conducted since no milk animals are located within a radius of approximately five miles of the plant in any sector and is used to simulate dose to an individual via the milk pathway for compliance purposes.

21

Food Products During 2007, since no gardens were irrigated with water influenced by the plant effluent, no food crops were required to be obtained. Nonetheless, some samples were obtained from control location (FP-49) and indicator location (FP-58) food products (collards and tomatoes). No gamma activity associated with plant operation was detected in any control or indicator samples in 2007.

Shoreline Sediment In 2007, no gamma activity associated with plant operation was detected in any sample in the semiannual shoreline sediment samples. Only naturally occurring gamma activity was detected.

Cs- 137 activity seen in past years was attributed to worldwide fallout and not the plant operation.

No Cs-137 activity was detected in 2007.

Bottom Sediment Cs-137 activity was detectable in 3 of the 3 indicator bottom sediment samples in 2007, with an average concentration of 3.96E-1 pCi/g (dry). The control sample indicated detectable Cs-137 activity with a concentration of 8.96E-2 pCi/g (dry). Cobalt-60 (Co-60) activity was detectable in 2 of the 3 indicator samples with an average concentration of 1.11E-1 pCi/g (dry). No other.

gamma activity, except for naturally occurring gamma activity, was detected in the annual bottom sediment samples in 2007. The bottom sedimentmonitoring program added a sample location (SD-66) in August of 2007 at the request of ANI (American Nuclear insurers) to monitor the effects of the plant on Prestwood Lake. The new location is not an ODCM requirement.

Aquatic Vegetation In 2007, there were three aquatic vegetation indicator samples collected and one aquatic vegetation control sample collected. The aquatic vegetation samples collected pose no dose consequence since this is not a dose pathway. No gamma activity, except for naturally occurring 22

gamma activity, was detected in the annual control aquatic vegetation sample; however, Co-58 activity was detectable in 3 of 3 indicator samples with an average concentration of 7.57E-2 pCi/g (wet) in 2007. The aquatic vegetation monitoring program added a sample location (AV-

66) in August of 2007 at the request of ANI (American Nuclear Insurers) to monitor the effects of the plant on Prestwood Lake. The new location is not an ODCM requirement.

Surface Water Surface waters of Lake Robinson indicated the presence of tritium which is attributed to plant operation. Figure 13 displays the tritium activity throughout 2007. These surface waters do not supply drinking water at any downstream location and are not used for irrigation. Therefore, radiological dose via this pathway is limited to the consumption of fish from Lake Robinson.

Using the methodology of Regulatory Guide 1.109, Equation A-1, (below) a dose of 0.004 millirem/year to the maximum exposed individual could be assigned to this pathway.

Equation A- I Raipj = Cip Uap Daipj where:

Raipj = total body dose in mrem/yr due to H-3 Cip = concentration of nuclide (H-3) in pCi/kg = pCi/l Uap = maximum exposed individual's consumption (Reg. Guide 1.109, Table E-5) (46 lbs. of fish per year = 21 kg of fish/yr.)

Daipj ingestion dose factor for total body of individual (adult) in Uap in mrem/pCi (Reg. Guide 1.109 Table E- 11)

The monthly composite gamma analyses for surface water samples revealed no radionuclides typical of plant effluents. The surface water monitoring program added a sample location (SW-

66) in August of 2007 at the request of ANI (American Nuclear Insurers) to monitor the effects of the plant on Prestwood Lake. The new location is not an ODCM requirement.

23

External Radiation Direct radiation exposure in the HBRSEP environs was measured by the placement of thermoluminescent 'dosimeters (TLDs) around the plant forming an inner ring at approximately 1 mile and an outer ring at approximately 5 miles. The average of inner versus outer ring dose measurements is shown on Figure 14.

Asiatic Clams Benthic samples from Lake Robinson during 2007 continue to confirm the absence of any substantial populations of Asiatic clams (Corbiculafluminia). The natural chemistry of the lake (i.e., low alkalinity and hardness) inhibits their proliferation.

MISSED SURVEILLANCES Air Cartridge and Air Particulates Any REMP weekly air samples (Air Cartridge - AC or Air Particulate - AP (APAC)) that exceed 30 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months of down time in a surveillance period will be reported as a "missed surveillance". However, this sample will still be counted and the data reported; whereas a "missed sample" indicates that no sample was available and no data was reported.

All AP and AC samples were available for counting in 2007; however, one set of APAC samples was an outlier. The outlier was deemed to not be a representative result; therefore, it will be reported as a Missed Sample.

Missed Samples:

APAC-55 May 7, 2007 - Total run time was 42.3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months . Down time of 101.7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months was due to the unit tripping due to an under voltage. The air sampler was found not running and the fuse was replaced, but still no response. Telemetry history was reviewed and notification items were updated to also include under voltage (NCR # 232234).

Missed Surveillances:

" APAC-55, April 9 - Total run time was 98.4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months . The air sampler was found not running and the fuse was blown. Replaced the fuse and the unit was returned to service (NCR #228925).

APAC-5, April 24 - Total run time was 118.1 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . The air sampler was found running.

No known cause for the down time was noted. This missed surveillance was determined during the annual review (NCR # 271436).

" APAC-6, July 16 - Total run time was 76.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months . The air sampler was found not running. The sampler had been struck by lighting on 6/23/07, the fuse was replaced but the sampler was not running continuously. It would stop running and restart itself. The telemetric modual was replaced and the sampler is running continuously (NCR #

239619).

25

Broadleaf Vegetation Broadleaf vegetation (BL) samples were not available during the months of January, February, March, April, November, and December of 2007 due to the seasonal nature of broadleaf vegetation (NCR # 218932, 222671, 226124, 229470, 255614, and 259247). Only one type of broadleaf vegetation was available in October of 2007 for sampling due to the seasonal unavailability of the vegetation (NCR # 251829).

Thermoluminescent Dosimeters (TLDs)

Four of a possible 172 TLD samples were missing during 2007.

First Quarter: TLD # 26 was missing in the field from the power pole on which it was located. A search of the area did not locate the missing TLD (NCR #

228930).

Third Quarter: TLD # 11 was missing in the field due to the power pole it was located on was cut down. The area was searched, but the TLD could not be located (NCR # 249867).

TLD # 18 was missing in the field from a tree located near remnants of Black Creek Railroad trestle. The TLD could not be located (NCR #

249867).

Fourth Quarter: TLD # 30 was determined to be missing after TLD results were processed.

A search of the HE & EC TLD Lab was conducted, but the TLD was not located. The cause of the missing TLD cannot be definitely determined, but two probable causes are: (1) package came in without a TLD in it or (2) the TLD was inadvertently disposed with the plastic bag from the HE &

EC TLD Lab location. Improved handling and accountability of the TLDs upon receipt were discussed with personnel (NCR # 266130).

ANALYTICAL PROCEDURES Gross Beta Gross beta radioactivity measurements are made using a Tennelec Low-Background Alpha/Beta 3

Counting System. The LLD for air particulates is approximately 2.2E-3 pCi/m .

Air particulate samples are mounted in 2-inch stainless steel planchets and 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. Five milliliters of the distillate are mixed with thirteen milliliters of liquid scintillation cocktail and counted in a liquid scintillation counter typically for 200 minutes. The lower LLD (3.50E+2 pCi/L) was established for consistency with the state laboratory for valid comparisons.

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 is typically counted for 900 seconds individually with an approximate LLD of 6.3E-2 pCi/m3 .

Gamma Spectrometry Gamma spectrum analysis uses intrinsic germanium detectors with thin aluminum windows housed in steel and lead shields. The analyzer system is the Canberra Nuclear 9900 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).

27

Air particulate quarterly composite filters are placed in a Petri dish and analyzed directly for a typical count time of 2,000 seconds.

Liquid samples are boiled down to reduce the volume, transferred to a PB-50 beaker, and are typically analyzed directly for 8,400 seconds for groundwater and 40,000 seconds for surface water samples.

Shoreline and bottom sediments are dried, ground, weighed, and then analyzed in a 1-liter Marinelli beaker typically for 1,500 seconds.

Broadleaf and aquatic vegetation and food product samples are weighed wet and analyzed in a Marinelli beaker for typically 7,500 seconds.

Fish samples are prepared by stuffing small raw, edible portions of the fish in a 1-liter Marinelli beaker for gamma analysis and are typically counted for 3,200 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.

28

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 Analytics Environmental Cross Check Program and 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. From these individual measurements, average results are calculated for each sample medium. During 2007, 66 average analyses were completed on 16 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 66 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.

All of the 66 average analyses were within the acceptance criteria, except for one Gross Beta on Filter for Cs-137 result which fell outside the acceptable criteria (NCR # 267497). During 2007, each individual measurement (691 analyses) was evaluated; with all but twenty-five (25) of the individual measurements falling within the acceptable criteria (NCR # 273324). Any results that lie outside the ratio criteria have had an evaluation performed to identify any recommended remedial actions and to reduce anomalous errors. Complete documentation of any evaluation will be available and provided to the NRC upon request.

Lower Limits of Detection The samples analyzed met the "a priori" LLD required by the ODCM. Typical "a priori" LLD values for the samples analyzed are listed in Table 6.

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 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 once per 24 months during the growing season. 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 asprovide data for the calculation of estimated radiation exposure.

The pathways that are evaluated are:

" Ingestion Pathway - Results from eating food products that may have radioactive materials deposited on them, incorporated radioactive materials from the soil or atmosphere. Another pathway is through drinking milk from local cows or goats if 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.

32

Methodology The following must be identified within the five (5) mile radius of the plant for each of the sixteen meteorological sectors (compass direction the winds may blow, for example NNE [North North East]):

The nearest resident

" The nearest garden of greater that 500 square feet, producing broadleaf vegetables

The nearest milk animal

" The nearest meat/egg producing animal The primary method is visual inspection from roadside within the five (5) mile radius. This information is supplemented with data from aerial photographs, information from county extension agents, farm supply businesses, and knowledge of the area.

Land Use Census Results There was no Land Use Census performed in 2007 per RNP's ODCM 4.4.1, which states that the land use census shall be conducted once per 24 months during the growing season. The last RNP land use census was performed in June 2006. The 2006 and 2004 results of the survey for the nearest resident, garden, milk producing animal, and meat/egg producing animal for each meteorological sector are compared in Table 7.

No milk producing animals were identified within five-mile radius of the site in any sector.

Also, no garden (at the time of the census) is currently growing leafy vegetables. Vegetables like tomatoes, squash, okra, cucumbers, watermelons, etc. are examples of the vegetables of choice for this area and are what is typically grown and sampled in the past. Sampling of these vegetables (non-leafy) will continue until leafy vegetables can be identified. Milk sampling will resume if a new sample location is identified.

Radiological Environmental Monitoring Analysis Report Comments

" Efficiency values are not included for AC samples requiring radioiodine analysis (1-13 1), because gamma software does not report these values.

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