SUMMARY

This Annual Radiological Environmental Operating Report describes the Catawba Nuclear

Station Radiological Environmental Monitoring Program (REMP), and the program results for the calendar year 2012.

Included are the identification of sampling locations, descriptions of environmental sampling and analysis procedures, comparisons of present environmental radioactivity levels and pre-operational environmental data, comparisons of doses calculated from environmental 0measurements and effluent data, analysis of trends in environmental radiological data as 0potentially affected by station operations, and a summary of environmental radiological sampling results. Quality assurance practices, sampling deviations, unavailable samples, and program changes are also discussed.

0Sampling activities were conducted as prescribed by Selected Licensee Commitments

(SLCs). Required analyses were performed and detection capabilities were met for all

- collected samples as required by SLCs. Eight-hundred ninety samples were analyzed comprising 1,202 test results in order to compile data for the 2012 report. Based on the 0annual land use census, the current number of sampling sites for Catawba Nuclear Station is

sufficient.

Concentrations observed in the environment in 2012 for station related radionuclides were generally within the ranges of concentrations observed in the past. Inspection of data showed 0that radioactivity concentrations in surface water, drinking water, shoreline sediment, and

fish are higher than the activities reported for samples collected prior to the operation of the

station. Measured concentrations were not higher than expected and all positively identified measurements attributable to station operation were within limits as specified in SLCs.

Additionally, environmental radiological monitoring data is consistent with effluents

introduced into the environment by plant operations. The total body dose estimated to the maximum exposed member of the public as calculated by environmental sampling data, excluding TLD results, was 8.55E-02 mrem for 2012. Background radiation dose in the

United States is approximately 620 mrem per year (approximately half from naturally occurring sources such as radon and half from man-made sources such as medical processes)

(reference 6.13). It is therefore concluded that station operations has had no significant radiological impact on the health and safety of the public or the environment.

2.0 INTRODUCTION

2.1 SITE DESCRIPTION AND SAMPLE LOCATIONS Duke Energy Corporation's Catawba Nuclear Station is a two-unit facility located on the shore

of Lake Wylie in York County, South Carolina. Each of the two essentially identical units employs a pressurized water reactor nuclear steam supply system furnished by Westinghouse Electric Corporation. Each generating unit is designed to produce a net electrical output of approximately 1145 MWe. Units 1 and 2 achieved initial criticality on January 7, 1985, and 8, 1986, respectively.

0*May Condenser cooling is accomplished utilizing a closed system incorporating cooling towers, instead of using lake water directly. Liquid effluents are released into Lake Wylie via the station discharge canal and are not accompanied by the large additional dilution water flow 0associated with "once-through" condenser cooling. This design results in greater radionuclide concentrations in the discharge canal given comparable liquid effluent source terms.

Figures 2.1-1 and 2.1-2 are maps depicting the Thermoluminescent Dosimeter (TLD) 0 monitoring locations and the sampling locations. The location numbers shown on these maps

correspond to those listed in Tables 2.1-A and 2.1-B. Figure 2.1-1 comprises all sample

locations within a one mile radius of CNS. Figure 2.1-2 comprises all sample locations within a 10 mile radius of CNS.

2.2 SCOPE AND REQUIREMENTS OF THE REMP 0

0An environmental monitoring program has been in effect at Catawba Nuclear Station since

1981, four years prior to operation of Unit 1 in 1985. The preoperational program provides

data on the existing environmental radioactivity levels for the site and vicinity which may be used to determine whether increases in environmental levels are attributable to the station. The 0operational program provides surveillance and backup support of detailed effluent monitoring 0which is necessary to evaluate the significance, if any, of the contributions to the existing environmental radioactivity levels that result from station operation.

This monitoring program is based on NRC guidance as reflected in the Selected Licensee 0Commitments Manual, with regard to sample media, sampling locations, sampling frequency and analytical sensitivity requirements. Indicator and control locations were established for comparison purposes to distinguish radioactivity of station origin from natural or other "man-made" environmental radioactivity. The environmental monitoring program also verifies 0projected and anticipated radionuclide concentrations in the environment and related exposures 0from releases of radionuclides from Catawba Nuclear Station. This program satisfies the

requirements of Section IV.B.2 of Appendix I to 10CFR50 and provides surveillance of all appropriate critical exposure pathways to man and protects vital interests of the company, public and state and federal agencies concerned with the environment. Reporting levels for

activity found in environmental samples are listed in Table 2.2-A.

Table 2.2-B lists the REMP analysis and frequency schedule.

The Annual Land Use Census, required by Selected Licensee Commitments, is performed to 0 ensure that changes in the use of areas at or beyond the site boundary are identified and that modifications to the REMP are made if required by changes in land use. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR50. Results are shown in Table 3.11.

Participation in an interlaboratory comparison program as required by Selected Licensee Commitments provides for independent checks on the precision and accuracy of measurements of radioactive material in REMP sample matrices. Such checks are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results 0 are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR50. A summary of the results obtained as part of this comparison program are in Section 5 of this annual report.

2.3 STATISTICAL AND CALCULATIONAL METHODOLOGY 2.3.1 ESTIMATION OF THE MEAN VALUE 0

There was one (1) basic statistical calculation performed on the raw data resulting from 0 the environmental sample analysis program. The calculation involved the determination of the mean value for the indicator and the control samples for each sample medium. The mean is a widely used statistic. This value was used in the 0 reduction of the data generated by the sampling and analysis of the various media in the Radiological Environmental Monitoring Program. "Net activity (or concentration)" is the activity (or concentration) determined to be present in the sample. No "Minimum Detectable Activity", "Lower Limit of Detection", "Less Than Level", or negative activities or concentrations are included in the calculation of the mean. The following 0 equation was used to estimate the mean (reference 6.8):

N 0 X - ilN Where: 0 0

x = estimate of the mean, i = individual sample, N = total number of samples with a net activity (or concentration), O Xi = net activity (or concentration) for sample i. 0 0

O 2.3.2 LOWER LEVEL OF DETECTION AND MINIMUM O DETECTABLE ACTIVITY O The Lower Level of Detection (LLD), and Minimum Detectable Activity (MDA) are O used throughout the REMP.

- LLD - The LLD, as defined in the Selected Licensee Commitments Manual is the 0 smallest concentration of radioactive material in a sample that will yield a net count,

above the system background, that will be detected with 95% probability with only 5%

probability of falsely concluding that a blank observation represents a "real" signal.

The LLD is an a priorilower limit of detection. The actual LLD is dependent upon the standard deviation of the background counting rate, the counting efficiency, the sample size (mass or volume), the radiochemical yield and the radioactive decay of the sample between sample collection and counting. The "required" LLD's for each sample medium and selected radionuclides are given in the Selected Licensee Commitments 0 and are listed in Table 2.2-C.

O MDA - The MDA is the net counting rate (sample after subtraction of background) that must be surpassed before a sample is considered to contain a scientifically measurable amount of a radioactive material exceeding background amounts. The MDA is calculated using a sample background and may be thought of as an "actual" LLD for a particular sample measurement.

2.3.3 TREND IDENTIFICATION O One of the purposes of an environmental monitoring program is to determine if there is a buildup of radionuclides in the environment due to the operation of the nuclear station. Visual inspection of tabular or graphical presentations of data (including preoperational) is used to determine if a trend exists. A decrease in a particular 0 radionuclide's concentration in an environmental medium does not indicate that reactor O operations are removing radioactivity from the environment but that reactor operations are not adding that radionuclide to the environment in quantities exceeding the preoperational level and that the normal removal processes (radioactive decay, deposition, resuspension, etc.) are influencing the concentration.

0 Substantial increases or decreases in the amount of a particular radionuclide's release from the nuclear plant will greatly affect the resulting environmental levels; therefore, a 5 knowledge of the release of a radionuclide from the nuclear plant is necessary to 0 completely interpret the trends, or lack of trends, determined from the environmental 0 data. Factors that may affect environmental levels of radionuclides include prevailing weather conditions (periods of drought, solar cycles or heavier than normal precipitation), construction in or around either the nuclear plant or the sampling 0 location, and addition or deletion of other sources of radioactive materials (such as the 0 Chernobyl accident). Some of these factors may be obvious while others are sometimes 50 unknown. Therefore, how trends are identified will include some judgment by plant personnel.

3.0 INTERPRETATION OF RESULTS

Review of all 2012 REMP analysis results was performed to identify changes in environmental levels as a result of station operations. The following section depicts and explains the review of these results. Sample data for 2012 was compared to preoperational 0and historical data. Over the years of operation, analysis and collection changes have taken place that do not allow direct comparisons for some data collected from 1984 (preoperational) through 2012. Summary tables containing 2012 information required by Technical Specification Administrative Control 5.6.2 are located in Appendix B.

0Evaluation for significant trends was performed for radionuclides that are listed as required

within Selected Licensee Commitments 16.11-13. The radionuclides include: H-3, Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Cs-134, Cs-137, Ba-140 and La-140.

0Gross beta analysis results were trended for drinking water and gross beta trending for air

particulates was initiated in 1996. Other radionuclides detected that are the result of plant operation, but not required for reporting, are trended.

0A comparison of annual mean concentrations of effluent-based detected radionuclides to 0historical results provided trending bases. Frequency of detection and concentrations related

to SLC reporting levels (Table 2.2-A) were used as criteria for trending conclusions. All 2012

maximum percentages of reporting levels attributed to CNS operation were well below the 100% action level. The highest value reached during 2012 due to CNS operation was 8.00%

0*for H-3 in drinking water sample collected from location 214.

Selected Licensee Commitment section 16.11-13 addresses actions to be taken if radionuclides other than those required are detected in samples collected. The occurrences of these radionuclides are the result of CNS liquid effluents which contained the radionuclides.

0

During 1984-1986, all net activity results (sample minus background), both positive and

negative were included in calculation of sample mean. A change in the EnRad gamma spectroscopy system on September 1, 1987, decreased the number of measurements yielding

detectable low-level activity for indicator and control location samples. It was thought that 10 the method used by the previous system was vulnerable to false-positive results.

0 All 2012 sample analysis results were reviewed to detect and identify any significant trends.

Tables and graphs are used throughout this section to display data from effluent-based

radionuclides identified since the system change in late 1987. All negative concentration values were replaced with zero for calculation purposes. Any zero concentrations used in tables or graphs represent activity measurements less than detectable levels.

0Review of all 2012 data presented in this section supports the conclusion that there were no 0significant changes in environmental sample radionuclide concentrations of samples collected and analyzed from CNS site and surrounding areas that were attributable to plant operations.

3.1 AIRBORNE RADIOIODINE AND PARTICULATES 0 In 2012, 260 radioiodine and particulate samples were analyzed, 208 from four indicator 0

locations and 52 at the control location. Particulate samples were analyzed weekly for gamma and gross beta. Radioiodine samples received a weekly gamma analysis.

0 Figure 3.1 shows individual sample gross beta results for the indicator location with highest 0 annual mean and the control location samples during 2012. The two sample locations' results are similar in concentration and have varied negligibly since preoperational periods.

There were no detectable gamma emitters identified for particulate filters analyzed during 0 2012. Table 3.1-A shows the highest indicator annual mean and control location annual mean for gross beta in air particulate.

0 There was no detectable 1-131 in air radioiodine samples analyzed in 2012. Table 3.1-B shows the highest indicator annual mean and control location annual mean for 1-131 since 1984 (preoperational period). The table shows similar concentrations for both the indicator 0 and control locations and the activities decreasing from early in the operational history of the 0 plant. No 1-131 activity due to CNS plant operations has been detected since 1987.

K-40 and Be-7 that occur naturally were routinely detected in charcoal cartridges collected 0 during the year.

0 0 3.2 DRINKING WATER 0 Gross beta and gamma spectroscopy were performed on 26 drinking water samples. The samples were composited to create 8 quarterly samples that were analyzed for tritium. One indicator location was sampled, along with one control location.

0 0 No gamma emitting radionuclides were identified in 2012 drinking water samples. There have been no gamma emitting radionuclides identified in drinking water samples since 1988.

0 Table 3.2 shows highest annual mean gross beta concentrations for the indicator location and 0 control location since preoperation. The indicator location (downstream of the plant effluent release point) average concentration was 1.89 pCi/l in 2012 and the control location 0 concentration was 1.84 pCi/1. The 2011 indicator mean was 2.01 pCi/l. The table shows that 0 current gross beta levels are not statistically different from preoperational concentrations.

Tritium was detected in the four indicator samples and the four control samples during 2012.

0 The mean indicator tritium concentration for 2012 was 954 pCi/l, 4.77% of reporting level.

0 The mean control tritium concentration for 2012 was 502 pCi/I, 2.51% of reporting level.

Figure 3.2 and Table 3.2 display the highest indicator and control location annual mean concentrations for tritium since 1984.

0 The concentration of tritium in drinking water is affected by releases from the Catawba plant 0 and the McGuire Nuclear Station, located approximately 40 miles upstream of the Catawba plant on the Catawba River.

0 The dose for consumption of water was less than one mrem per year, historically and for 0 2012; therefore low-level iodine analysis is not required.

3.3 SURFACE WATER 0

0 A total of 39 monthly surface water samples were analyzed for gamma emitting radionuclides. The samples were composited to create 12 quarterly samples for tritium 0 analysis. Two indicator locations and one control location were sampled. One indicator location (208) is located near the liquid effluent discharge point.

All 2012 indicator location samples contained tritium with an average concentration of 6,510 pCil. Indicator Location 208 (Discharge Canal) showed a range of activities from 3,650 to 0 33,000 pCi/1 which had the highest mean concentration of 12,100 pCi/l. Tritium was detected in all four control samples during 2012 with an average concentration of 371 pCi/l. Tritium in 0 surface water was higher in 2012 than in the past several years due to dual unit shut down that 0 occurred in December of 2011. A larger than normal amount of water was released from the plant to support the shutdown. This activity is addressed in reference 6.15.

No gamma emitting radionuclides were identified in 2012 surface water samples. Gamma 0 spectroscopy analysis detected Co-58 and Co-60 in one indicator sample during 2011. Table 3.3 summarizes the indicator annual means of radionuclides detected since the change in the 0 gamma spectroscopy analysis system in 1987. Visual inspection of the tabular data did not reveal any increasing trends.

0 S Figure 3.3 displays the highest indicator and control annual means for tritium since 1984.

Table 3.3 lists the highest indicator annual means.

0 The concentration of tritium in surface water is affected by releases from the Catawba plant and the McGuire Nuclear Station, located approximately 40 miles upstream of the Catawba plant on the Catawba River.

0 Co-58 and Co-60 were identified in two samples collected from indicator location 208, S which is closest to the plant's liquid effluent release point. Cs- 137 was identified in one sample collected from location 208. Naturally occurring K-40 was identified in many of S the indicator and control locations. Activity released in plant effluents has decreased since 1996 and as a result decreased activity has been measured in the environment.

0 The shoreline sediment location with the highest annual mean for all detectable 0 radionuclides was location 208. Radionuclides identified at location 208 consist of Co-58 with an annual mean concentration of 55.9 pCi/kg, Co-60 with an annual mean concentration of 170 pCi/kg, and Cs-137 with an annual mean concentration of 31.5 pCi/kg. Naturally occurring K-40 and Be-7 were also identified in samples from this location.

Table 3.9 lists highest indicator location annual mean since 1984. Included in the table are radionuclides that have been identified in shoreline sediment samples since 1988.

Figures 3.9-1, 3.9-2, and 3.9-3 are graphs displaying annual mean concentrations for Co-58, Co-60, and Cs-137.

3.10 DIRECT GAMMA RADIATION 3.10.1 ENVIRONMENTAL TLD 0 In 2012, 164 TLDs were analyzed, 152 at indicator locations and 12 at control locations. TLDs are collected and analyzed quarterly. A transit background for environmental TLDs is determined based on ANSI N545. The highest annual mean exposure for an indicator location was 96.0 milliroentgen. The annual mean exposure for the control locations was 61.3 milliroentgen.

Figure 3.10-1 and Table 3.10-A show TLD inner ring (site boundary),

outerRing (4-5 miles), and control location annual averages in milliroentgen per year. Preoperational data and rolling ten year operational data averages are also given. As shown in the graph, inner ring, outer ring, and control data averages historically compare closely. Inner and outer ring averages comprise a number of data points with control averages representing only three locations.

Figures 3.10-2 and 3.10-3 show the TLD mean for each inner and outer ring TLD location from 1986 through 2012.

The calculated total body dose (from gaseous effluents) for 2012 was 1.93E0 mrem, which is 2.41% of the average inner ring TLD values. Therefore, it can be concluded that discharges from the plant had very little impact upon the measured TLD values.

A TLD intercomparison program is conducted as part of the quality assurance program. Results of this program are included in section 5.10.

3.10.2 ISFSI 0 The Catawba Independent Spent Fuel Storage Installation (ISFSI) is a secured area constructed to provide dry storage for spent nuclear fuel. The principal components of the ISFSI are concrete vertical storage modules that hold stainless steel dry storage canisters containing irradiated fuel assemblies. 0 The ISFSI is located approximately 300 meters north of the Unit 2 reactor building. TLD results are evaluated quarterly to identify trends and demonstrate compliance with dose and dose rate limits at the ISFSI boundaries, the Owner Control fence north of ISFSI and at the Exclusion Area Boundary in the west sector. Catawba began storage of spent fuel at the ISFSI in 2007.

0 Doses measured by environmental TLDs show little or no change since the current TLD system was implemented.

0 S 3.11 LAND USE CENSUS The 2012 Annual Land Use Census was conducted July 9, and July 10, 2012 as required by SLC 16.11-14. Table 3.11 summarizes census results. A map indicating identified locations is shown in Figure 3.11.

During the 2012 census no irrigated gardens (superior to existing gardens) or milk locations were identified. The nearest residence is located in the NE sector at 0.56 miles.

No environmental program changes were required as a result of the 2012 land use census.

4.0 EVALUATION OF DOSE

4.1 DOSE FROM ENVIRONMENTAL MEASUREMENTS 0Annual doses to maximum exposed individuals were estimated based on measured

concentrations of radionuclides in 2012 CNS REMP samples. The primary purpose of estimating doses based on sample results is to allow comparison to effluent program dose estimates.

0Doses based on sample results were calculated using the methodology and data

presented in NRC Regulatory Guide 1.109. Measured radionuclide concentrations, averaged over the entire year for a specific radionuclide, indicator location and sample type, were used to calculate REMP-based doses. Where applicable, average background concentration at the corresponding control location was subtracted. Regulatory Guide 01.109 consumption rates for the maximum exposed individual were used in the

calculations. When the guide listed "NO DATA" as the dose factor for a given radionuclide and organ, a dose factor of zero was assumed.

Maximum dose estimates (Highest Annual Mean Concentration) based on broadleaf vegetation, drinking water, fish, and shoreline sediment sample results are reported in

- Table 4.1-A. The individual critical population and pathway dose calculations are reported in Table 4.1-B.

REMP-based dose estimates are not reported for airborne radioiodine, airborne

particulate, milk, or ground water sample types because no radionuclides attributable to CNS operations were detected. Naturally occurring K-40 and Be-7 were detected in some samples but were not included in any REMP-based dose estimates. Dose 0estimates are not reported for surface water because sampled surface water is not considered to be a potable drinking water source although surface water tritium concentrations are used in calculating doses from fish. Exposure estimates based upon 0 REMP TLD results are discussed in Section 3.10.

0The maximum environmental organ dose estimate for any single sample type (excluding

TLD results) collected during 2012 was 6.54E-2 mrem to the adult liver from consuming fish.

4.2 ESTIMATED DOSE FROM RELEASES 0

Throughout the year, dose estimates were calculated based on actual 2012 liquid and gaseous effluent release data. Effluent-based dose estimates were calculated using the

RETDAS computer program which employs methodology and data presented in NRC

Regulatory Guide 1.109. These doses are shown in Table 4.1-A along with the

corresponding REMP-based dose estimates. Summaries of RETDAS dose calculations are reported in the Annual Radioactive Effluent Release Report (reference 6.6).

~Section 4 -Page 1 0

The effluent-based liquid release doses are summations of the dose contributions from the drinking water, fish, and shoreline pathways. For iodine, particulate, and tritium exposure the effluent-based gaseous release doses are summations of the dose 0 contributors from ground/plane, inhalation, milk and vegetation pathways.

4.3 COMPARISON OF DOSES The environmental and effluent dose estimates given in Table 4.1-A agree reasonably well. The similarity of the doses indicate that the radioactivity levels in the environment do not differ significantly from those expected based on effluent measurements and modeling of the environmental exposure pathways. This indicates that effluent program dose estimates are both valid and reasonably conservative.

There are some differences in how effluent and environmental doses are calculated that affect the comparison. Doses calculated from environmental data are conservative because they are based on a mean that includes only samples with a net positive activity versus a mean that includes all sample results (i.e. zero results are not included in the mean). Also, airborne tritium is not measured in environmental samples but is used to calculate effluent doses.

Additionally, in 2010 Catawba began reporting estimated dose from effluent Carbon 14 (C-14). This change came about with the issuing of Regulatory Guide 1.21, Revision 2, Measuring, Evaluating and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste. A description of this change is found in the 2010 Annual Radiological Effluent Release Report. C-14 is not measured in the environment and therefore, environmental and effluent doses from C-14 cannot be compared directly.

In calculations based on liquid release pathways, drinking water, fish, and shoreline sediment were the predominant dose pathways based on environmental and effluent data. The maximum total organ dose based on 2012 environmental sample results was 1.O1E-1 mrem to the child liver. The maximum total organ dose of 7.68E-2 mrem for liquid effluent-based estimates was to child liver.

In calculations based on gaseous release pathways, vegetation was the predominant dose pathway for effluent samples. The maximum total organ dose for gaseous effluent estimates was 4.49E0 mrem to the child bone. No radioactivity was detected from gaseous pathways in environmental samples; therefore, there is no calculated dose. 0 The doses calculated do not exceed 40CFR190 or 10CFR50 dose commitment limits for members of the public. Doses to members of the public attributable to the operation of CNS are being maintained well within regulatory limits.

0 ENVIRONMENTAL SAMPLING AND 0 ANALYSIS PROCEDURES 0 0

Adherence to established procedures for sampling and analysis of all environmental media at Catawba Nuclear Station was required to ensure compliance with Station Selected Licensee Commitments. Analytical procedures were employed to ensure that Selected Licensee Commitments detection capabilities were achieved.

Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, Fisheries and Aquatic Ecology.

This appendix describes the environmental sampling frequencies and analysis procedures by media type.

I. CHANGE OF SAMPLING PROCEDURES 0 No changes were made to the sampling procedure during 2012.

II. DESCRIPTION OF ANALYSIS PROCEDURES Gamma spectroscopy analyses are performed using high purity germanium gamma detectors and Canberra analytical software. Designated sample volumes are transferred to appropriate counting geometries and analyzed by gamma spectroscopy. Perishable samples such as fish and broadleaf vegetation are ground to achieve a homogeneous mixture. Soils and sediments are dried, sifted to remove foreign objects (rocks, clams, glass, etc.) then transferred to appropriate counting geometry.

Low-level iodine analyses are performed by passing a designated sample aliquot through a pre-weighed amount of ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk). The resin is then dried, mixed thoroughly, and a net resin weight determined before being transferred to appropriate counting geometry and analyzed by gamma spectroscopy.

Tritium analyses are performed quarterly by using low-level environmental liquid scintillation analysis technique on a Packard 2550 liquid scintillation system or Perkin-Elmer 2900TR liquid scintillation system. Tritium samples are distilled and batch processed with a tritium spike and blank to verify instrument performance and sample preparation technique are acceptable.

Gross beta analysis is performed by concentrating a designated aliquot of sample precipitate and analyzing by Tennelec XLB Series 5 gas-flow proportional counters.

0 S

Appendix A - Page 2 5 S

Samples are batch processed with a blank to ensure sample contamination has not occurred.

III. CHANGE OF ANALYSIS PROCEDURES

No analysis procedures were changed during 2012.

IV. SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE PARTICULATE AND RADIOIODINE 0

Airborne particulate and radioiodine samples at each of five locations were

composited continuously by means of continuous air samplers. Air particulates were collected on a particulate filter and radioiodines were collected in a

charcoal cartridge positioned behind the filter in the sampler. The samplers are

designed to operate at a constant flow rate (in order to compensate for any filter

loading) and are set to sample approximately 2 cubic feet per minute. Filters and cartridges were collected weekly. A separate weekly gamma analysis was

performed on each charcoal cartridge and air particulate. A weekly gross beta

analysis was performed on each filter. The continuous composite samples were

collected from the locations listed below.

Location 200 Site Boundary (0.63 mi. NNE)

Location 201 = Site Boundary (0.53 mi. NE)

Location 205 = Site Boundary (0.25 mi. SW)

Location 212 = Tega Cay (3.32 mi. E)

Location 258 = Fairhope Road (9.84 mi. W)

A.2 DRINKING WATER Monthly composite drinking water samples were collected at each of two

locations. A gross beta and gamma analysis was performed on monthly

composites. Tritium analysis was performed on the quarterly composites. The

composites were collected monthly from the locations listed below.

Location 214 = Rock Hill Water Supply (7.30 mi. SSE)

Location 218 = Belmont Water Supply (13.5 mi. NNE)

A.3 SURFACE WATER Monthly composite samples were collected at each of three locations. A gamma Sanalysis was performed on the monthly composites. Tritium analysis was performed on the quarterly composites. The composites were collected monthly from the locations listed below.

Thermoluminescent dosimeters (TLD) were collected quarterly at forty-one 0 locations. A gamma exposure rate was determined for each TLD. TLD locations 0 are listed in Table 2.1-B. The TLDs were placed as indicated below.

S An inner ring of 16 TLDs, one in each meteorological sector in the general area of the site boundary.

0 An outer ring of 16 TLDs, one in each meteorological sector in the 6 to 8 0 kilometer range.

The remaining TLDs were placed in special interest areas such as population centers, residential areas, schools, and at three control locations.

A.11 ANNUAL LAND USE CENSUS An Annual Land Use Census was conducted to identify within a distance of 8 kilometers (5.0 miles) from the station, the nearest location from the site boundary in each of the sixteen meteorological sectors, the following:

The Nearest Residence

The Nearest Garden greater than 50 square meters or 500 square feet 0

The Nearest Milk-giving Animal (cow, goat, etc.)

0 0 The census was conducted during the growing season from 7/9 - 7/10/2012.

Results are shown in Table 3.11. No changes were made to the sampling 0 procedures during 2012 as a result of the 2012 census.
