SUMMARY

The purpose of the Energy Northwest Radiological Environmental Monitoring Program (REMP) is to evaluate the radiological impact that Columbia Generating Station (CGS) operation may have on the environment. Sampling is performed as specified in the Offsite Dose Calculation Manual (ODCM) and agreements made with the State of Washington Energy Facility Site Evaluation Council (EFSEC). Additional sampling is also performed to meet Nuclear Energy Institute (NED guidelines or an Energy Northwest initiative. Sampling and analysis is performed by the Energy Northwest Environmental Services group with analysis performed at the Applied Process Engineering Laboratory (APEL) facility located in Richland, Washington. Direct radiation services are provided by Pacific Northwest National Laboratory (PNNL). Specialized analyses may be contracted to other outside vendors as needed. A variety of environmental samples are routinely collected and analyzed by the REMP. Most samples are collected from locations that could potentially be affected by CGS operation. Some samples are also collected as controls from areas that could not reasonably be affected by CGS operation. The types of samples collected include air, water, soil, sediment, milk, fish, and garden produce. Additionally, the program monitors direct radiation at 79 different locations. Analysis results are trended and compared to results from control locations, results obtained in previous operational and pre-operational periods, and regulatory limits. The results contained in this report indicate that CGS operation had no significant radiological impact on the environment during 2009. The sample results are consistent with the results obtained from control locations, results from the preoperational period, and historical results collected since CGS began commercial operation. No unusual finding or adverse trends were observed. Most radioactive material identified in this report is of natural origin or known to be present in the environment around CGS in the quantities identified. Below is a summary of the 2009 results by exposure pathway: Direct Radiation - No impact was identified at locations beyond the CGS controlled area. Within the controlled area, the only impact identified was at locations known to be influenced by the Independent Spent Fuel Storage Installation (ISFSI) or radiation from the turbine building during operation. Airborne- No impact was identified. Waterborne- For surface/drinking water locations, the only impact identified was low level tritium in storm drain water attributed to recapture of CGS effluent tritium. Tritium identified in sanitary waste water is attributed to discharges made from facilities operated by the Department of Energy. For ground water, tritium activity identified is at levels consistent with levels known to exist in Hanford groundwater. Radionuclide activity identified in river sediment is consistent with activity levels known to exist in Hanford area sediment and soils. Ingestion- No impact was identified in any of the food sample results.

3.0 INTRODUCTION

3.0 - INTRODUCTION 3.1 Site Description The Columbia Generating Station is a 1200 MWe commercial nuclear power plant that achieved initial criticality on January 19, 1984. The plant is located in a sparsely populated shrub-steppe region within the Department of Energy (DOE) Hanford Site in southeastern Washington. The plant is approximately three miles west of the Columbia River and is surrounded on all sides by uninhabited desert land. The nearest large population centers are Richland, Pasco and Kennewick, which are 12 miles south, 18 miles southeast, and 21 miles southeast, respectively. The nearest privately owned lands are located approximately four miles east-northeast of the plant, across the Columbia River. The site has a bimodal wind pattern with winds primarily from the northwest and south.!1 7) The primary region of focus for REMP sampling is the farming region east of the plant. Naturally occurring radionuclides exist in detectable quantities throughout the world and are seen in many of the samples collected for the REMP. Some examples of naturally occurring radionuclides that are frequently seen in samples are K-40, Be-7, Ac-228 (present as a decay product of Ra-228), and Ra-226. Additionally, some relatively long lived anthropogenic radioisotopes, such as Sr-90 and Cs-137, are also seen in some REMP samples; these radionuclides exist in measurable quantities throughout the world as a result of fallout from atmospheric nuclear weapons testing. Due to the location of CGS on the Hanford Site, there are other sources of reactor produced radionuclides in close proximity to the plant. CGS is unique in the U.S. commercial nuclear power industry in this respect. Hanford related radionuclides, most notably tritium, are identified in some CGS REMP samples. Though the presence of these radionuclides in the vicinity of CGS are not necessarily reflective of CGS activity, changes in the levels of these radionuclides are monitored to assess any contribution that CGS may be making to the established background. The DOE has an active REMP program for the Hanford Site that overlaps the CGS REMP. 3.2 Program Background The CGS REMP is designed to conform to the Nuclear Regulatory Commission (NRC) Regulatory Guides 4.1,(') 4.8,'(2) and the Radiological Assessment Branch Technical Position. 3 ) In addition, the REMP also meets the requirements of 10 CFR 72.44(d)(2) for coverage of the ISFSI. The quality assurance aspects of the sampling program and the thermoluminescent dosimetry are conducted in accordance with Regulatory Guides 4.15(4) and 4.13.(5) The REMP also adheres to the requirements of the Washington Energy Facility Site Evaluation Council (EFSEC),(6" the Columbia Generating Station Technical Specifications(7) and the Offsite Dose Calculation Manual (ODCM).(8 ) These requirements cover the environmental sampling and sample analysis aspects of the program, and also the reporting and quality assurance requirements. The preoperational phase of the program, which lasted from March 1978 until initial criticality in January 1984, provided a baseline of background environmental data. Variability in the background levels of radioactivity over time is due to differences in geologic composition, meteorological 2009 Annual Radiological Environmental Operating Report 3-1 Energy Northwest/Columbia Generating Station

I conditions, decay of nuclear testing fallout material in the environment, and seasonal changes. Variability in results may also have been introduced by changing analytical contractors and the use of different correction factors over the years. The Energy Northwest Environmental Services Laboratory performed most REMP sample analyses in 2009. The Pacific Northwest National Laboratory processed the thermoluminescent dosimeters used for the REMP in 2009. N In addition to evaluating the environmental concentrations against regulatory limits, the REMP may also compare results to state standards.* 12, 13) The results may also be evaluated by comparing them I to similar measurements made during the preoperational and previous operational periods and to the detection capabilities associated with the current methods of analysis. I 3.3 Program Objectives The REMP provides an independent mechanism for determining the levels of radioactivity in the plant environs to ensure that any accumulation of radionuclides in the environment will not become a significant as a result of station operations or exceed established limits. While in-plant monitoring programs are used to ensure that 10 CFR 20(9) and 10 CFR 50(10) criteria for releases of radioactive effluents are met, the REMP provides direct verification of any environmental impact that may I result from plant effluents.

4.0 PROGRAM DESCRIPTION 4.0 PROGRAM DESCRIPTION The ODCM contains the CGS licensing based sampling requirements for the REMP. Additional sampling requirements are specified in resolutions with the Washington State Energy Facility Site Evaluation Council (EFSEC) or are self initiated in response to site specific or industry wide concerns. The sampling plan presented in Table 4-1 gives an overview of the REMP sampling routine, a summary of the sample locations, the specified collection frequency, and the types of analyses to be performed. The methods of sampling and sampling frequencies utilized in the program are mostly dictated by regulatory requirements. Factors such as nuclide half-lives and the major exposure pathways for the radionuclides potentially released from the plant have been taken into account in' determining the sampling methodology. 4.1 Sample Locations One hundred and thirteen sampling locations (referred to as 'stations') are included in the monitoring program. More than one sample type may be collected at a sample station. One hundred and four indicator and three control stations are located within a 10-mile radius of CGS. Six additional stations are located beyond the ten mile radius of the plant, two are indicator locations and 4 are control locations. Sample stations are listed in Tables 4-1 and 4-2. Most station locations are shown in Figures 4-1 to 4-4. The locations of most sample stations have been selected on the basis of an exposure pathway analysis. The exposure pathway analysis was based on factors such as weather patterns, anticipated emissions, likely receptors, and land use in the surrounding areas. Samples collected from stations located in areas that potentially could be influenced by CGS operation are used as indicators. Samples collected from locations that are not likely to be influenced by CGS operation serve as controls. Results from indicator stations are compared to the results from control stations and results obtained during the previous operational and preoperational years of the program in order to assess the impact CGS operation may be having on the environment. 4.2 Independent Spent Fuel Storage Installation (ISFSI) The Independent Spent Fuel Storage Installation (ISFSI) is a fenced, secured area constructed to provide a storage location for spent nuclear fuel. The spent fuel is stored in HI-STORM dry storage casks which are placed on concrete pads inside the facility. The pads are 30-feet wide by 135-feet long and each pad can hold up to 18 casks. The ISFSI is located approximately 500 meters north-northwest of the reactor building. REMP monitoring of the ISFSI is performed using quarterly and annual TLDs placed at 10 different locations on the outer security fence of the facility. In addition, two other TLD stations, Station 121 located approximately 200 meters north of the turbine building and Station 122 located approximately 100 meters north of the ISFSI, were installed to monitor ISFSI direct radiation. Figure 4-1 shows the ISFSI location in relation to CGS and the position of the 2 additional TLD locations. Figure 4-4 shows the location of the 10 TLD stations located around the ISFSI. This arrangement of TLDs in conjunction with the radiological surveys conducted by the CGS Radiation Protection Department serve as the radiological monitoring program for the ISFSI. 2009 Annual Radiological Environmental Operating Report 4-1 Energy North west/Columbi a Generating Station

I U 4.3 Land Use Census A land use census for areas within five miles of CGS is performed annually. The objective of the land m use census is to identify the locations of the nearest milk animal, residence, and garden greater than 500 ft2 producing broadleaf vegetation. This information is used to determine whether any site located during the census has a calculated dose or dose commitment greater than the sites currently monitored 5 for the same exposure pathway. If a new location with a higher dose commitment was found, routine sampling of that dose pathway would be initiated at that new site. The results of the 2009 land use census within five miles of CGS are presented in Table 4-3. No significant changes from the 2008 landI use census were observed. 4.4 Sampling Methods I Energy Northwest personnel collect environmental samples in accordance with the program plan outlined in Table 4-1. Methods of sample collection and TLD handling are specified in REMP specific procedures. Most REMP samples collected in 2009 were prepared and analyzed at the Energy a Northwest Environmental Services Laboratory located at the APEL facility in Richland, WA. The section 4.4 subsections below give a general overview of the sampling methods used in the REMP. I Generic descriptions of the REMP sample analysis methods are given in section 4.5. 4.4.1 Direct Radiation Direct radiation dose levels are monitored with Harshaw Model 8807 thermoluminescent dosimeters (TLDs). Two sets of TLDs are placed in the field approximately three feet above the ground at each monitoring station. One set of TLDs is exchanged on a quarterly basis (Quarterly TLDs); the other is exchanged on an annual basis (Annual TLDs). The locations of the TLD stations are listed in Table 4-2 and are shown in Figures 4-1 through 4.4. Station 9A in Sunnyside, serves as a control for CGS TLDs. Station 1 19C serves as the control for Station II 9B (the cooling tower sediment disposal basin). The remaining TLDs deployed in the field serve as indicator TLDs. The TLDs are arranged in a series of rings that encircle CGS. The innermost ring of TLD stations, which are located inside the CGS site boundary at distances that range from 0.3-0.8 miles from the u reactor building centerline, are referred to as the 'S stations.' The next ring of TLDs, referred to as the "near plant" stations, are located at distances ranging from 0.9 to 2.1 miles from the reactor building. The outer ring of TLDs are located at distances that range from a little under three miles to around tenl miles. A Thermo MicroRem dose rate meter is available as a backup device and to take real time readings as needed. 3 4.4.2 Airborne - Particulate/Iodine Weekly air particulate and air radioiodine (1-131) samples are obtained through the use of low volume (1.5 cfm), constant flow-rate sampling units located at 12 locations. The samples collected at station 9A 3 (Figure 4-3) are considered controls, the samples collected at the other locations (Figures 4-1, 4-2, and 4-3) are indicators. Air particulate samples are collected using 47mm diameter glass fiber filters, air1 iodine samples are collected using Radeco CP-100 TEDA impregnated charcoal cartridges. The air particulate filter and charcoal cartridge are placed in tandem, particulate filter first, in a holder that 2009 Annual Radiological Environmental Operating Report 4-2 Energy Northwest/Columbia Generating Station ii

attaches to the air inlet of the sampler unit. The sampler units are placed in ventilated metal weatherproof housings mounted on elevated platforms at each air sample location. The filter media are changed weekly. Four additional air sample locations established to monitor remediation work at the DOE 618-11 burial site utilize similar equipment. 4.4.3 Water Water sampling is performed to meet the requirements in the ODCM and State of Washington EFSEC requirements, comply with NEI guidelines, or a CGS initiative. REMP water sampling can be categorized as follows:

  • Intake-River/Drinking Water; two locations (Stations 26, and 29)
  • Deep Groundwater; three locations (Stations 52, 31, and 32)
  • Shallow Groundwater; eleven locations (MW-3 and MW-5 through MW-14)
    " Plant Discharge Water; one location (Station 27)
  • Storm Drain Water; one location (Station 101)
    " Sanitary Wastewater; two locations (Stations 102A, and 102B)

The sample at Station 26 is obtained using a composite sampler that draws water from the plant intake water system (TMU). The source of this water is the Columbia River. The station serves as a control location, as it is upstream of the plant discharge location, and also as a drinking water location as drinking water for CGS comes from this source. Station 29 is a composite sampler located at the Richland Water Treatment Plant located 11 miles downstream of the plant discharge. Station 29 is an indicator station for both river and drinking water. The ODCM requirement for a downstream water sample "near but beyond the mixing zone" is conservatively met by Station 27, a composite sampler that collects water from the cooling tower discharge line just prior to final discharge into the Columbia River. This sample reflects the radioactivity present in the plant discharge prior to any river dilution, rather than the concentrations that would be found after dilution in the mixing zone. Composite samples from Stations 26, 27, and 29 are collected monthly and analyzed for gamma emitting radionuclides, gross beta, and tritium. Three drinking water wells within the vicinity of CGS are used as groundwater sampling locations. These include a deep well on the CGS site, Station 52 located 0.1 mile north of the reactor building, and two deep wells at the IDC (ENW Industrial Development Complex), Station 31 and Station 32 located 1.2 miles down gradient from CGS. Water from Station 52 can be used as a backup source for drinking water and fire protection. The IDC wells supply water for drinking and fire protection at the IDC site. All of these wells are considered indicator locations. Quarterly grab samples are collected from each well and analyzed for gamma emitting radionuclides and tritium. Station 101 is a composite sampler that collects a representative sample of water flowing into the storm drain pond located east of CGS. The main source of this water is storm water runoff and discharges from the potable water and the plant makeup water demineralizer treatment systems. Additional discharges from CGS that have been verified to meet radiological environmental discharge limits may also be made to this location. Water is collected monthly using a flow-proportional composite sampler and analyzed for gross beta, gamma emitting radionuclides , and tritium. 2009 Annual Radiological Environmental Operating Report 4-3 Energy Northwest/Columbia Generating Station

I The Sanitary Waste Treatment Facility (SWTF) receives sanitary waste water from CGS, the IDC (ENW Industrial Development Complex), the Kootenai Building, and the DOE 400 Area. Discharge standards and monitoring requirements for the SWTF are established in EFSEC Resolution 300(15). Station 102A is a flow meter and composite sampler located on the DOE 400 Area sewer line before it I ties into the sewer lines coming from Energy Northwest facilities. A portion of the water used in the 400 Area is drawn from aquifers that are known to be contaminated with tritium as a result of past DOE activities on the Hanford Site, consequently, the water sampled at Station 102A has tritium I concentrations normally above 2000 pCi/liter. Station 102B is a composite sampler that collects a representative sample of water flowing into the head works at the SWTF. The sample obtained here contains water from all the Energy Northwest facilities mentioned above and the DOE 400 area. I Monthly samples are collected at both Stations 102A and 102B and analyzed for gross alpha, gross beta, tritium, and gamma emitting radionuclides. 3 Beginning in 2009, routine quarterly grab samples were taken as part of the REMP from a number of groundwater monitoring wells surrounding CGS. The monitoring well locations are shown in Figure 4-

1. All are shallow wells that allow sampling from the unconfined aquifer under CGS. None of the wells are used for drinking water. Sampling from these locations is performed to meet NEI 07-07 guidelines(2 1) and requirements in the CGS NPDES permit. 3 4.4.4 Soil Annual soil samples are collected at the indicator Stations 1,7, 21, and 23 as required by EFSEC I Resolution 260(b). A sample is also collected at a control location, Station 9A (Figure 4-3). Each sample is collected from an area of approximately one square foot to a depth of approximately one inch. About two kilograms of soil are collected for each sample. Soil samples are analyzed for gamma activity on a dry weight basis.

I 4.4.5 Sediment River sediment samples are collected semiannually as required by the ODCM and EFSEC Resolution 260(6). The upstream sediment sample location (Station 33) is approximately two miles upriver from the plant discharge. The downstream sample (Station 34) is collected approximately one mile downstream from the plant discharge. Each sample consists of approximately two kilograms of the shallow surface sediment scooped from below the waterline. Sediment samples are dried in an oven and then analyzed for gamma emitting radionuclides on a dry weight basis. Cooling tower sediment samples are collected and analyzed whenever cooling tower sediment is added to the disposal cells (Station I 19B, Figure 4-1). Disposal in the Station 1 19B cells is made in accordance with EFSEC Resolution No. 299(6). Wet cooling tower sediment samples are collected and analyzed prior to transfer to the disposal cells. Following transfer, the material is allowed to dry then an additional sample is collected within 30 days of the disposal date and analyzed. 4.4.6 Fish Annual fish sampling is usually performed in late fall. Fish samples collected from the Columbia River (Station 30) serve as indicator samples, whereas fish collected on the Snake River (Stations 38) serve as control samples. Only edible portions of the fish are used to prepare the sample for analysis. Fish samples are analyzed for gamma emitting radionuclides on a wet weight basis. 2009 Annual Radiological Environmental Operating Report 4-4 Energy Northwest/Columbia Generating Station a

Three categories of fish samples are collected; an anadromous species (either a salmon or steelhead), and two other species generally considered edible or potentially edible (such as carp, catfish, sucker, and whitefish) are collected at each location. Electro-shocking and netting is used for most fish collection. Anadromous species are usually collected at fish hatcheries. 4.4.7 Milk Milk samples are collected monthly during the fall and winter months (October through March). During the spring and summer months when cows are likely to be grazing or on fresh feed, milk samples are collected twice per month. Raw milk samples are collected within a few hours of milking and the samples are normally prepared and analyzed within four days. Milk samples were collected in 2009 from two locations. Station 36 in Franklin County serves as the indicator location and is the only dairy within a ten mile radius of CGS. Station 9B is in the Sunnyside/Grandview area and serves as the control location. 4.4.8 Garden Produce Samples of local garden produce are collected monthly during the growing season when the produce is readily available. When possible, three types of produce samples are collected; a root crop, a fruit, and a leafy vegetable. Control samples are usually obtained from the lower Yakima Valley. Indicator samples may be collected from any areas downstream of the CGS discharge where crops are irrigated with Columbia River water. These samples are designated as Station 37 and usually are collected in the Riverview area of Pasco. Additionally, apples are normally collected in late summer or early fall from Station 91, Rio Vista Farms, an orchard located on the Columbia River 4.3 miles ESE of CGS. A small garden/vegetation area supplying broadleaf samples is maintained by the Environmental Service personnel next to the SWTF and has been designated as Station 102G. A vegetation sample was also taken from a small park area near CGS (Station 103A) in 2009. Garden and vegetation samples are typically pur6ed in a food processor and then analyzed for gamma emitting radionuclides on a wet weight basis. Only edible portions are used for analysis. 4.5 Sample Analyses General descriptions of the procedures used to analyze REMP samples are provided in the following sections. The REMP TLDs were processed by Battelle at the Pacific Northwest National Laboratory (PNNL). Most REMP field samples were analyzed by Energy Northwest Environmental Services. Samples are normally collected and analyzed within a short time period to ensure required detection sensitivities are met and to provide timely results. Sample count times are conservatively calculated to ensure required a priori LLDs are achieved. Table 4-4 list the ODCM required LLDs and the nominal target LLD used in the Energy Northwest REMP program during 2009. 4.5.1 Analysis of TLDs The REMP TLDs are measured at the Pacific Northwest National Laboratory on a Harshaw Model 8800 hot gas reader. The reader is calibrated weekly and immediately prior to processing the environmental TLDs. The reader is calibrated with TLDs that have been given a known exposure from a Cs- 137 source. Each group of environmental TLDs is processed with blank (freshly annealed) TLDs 2009 Annual Radiological Environmental Operating Report 4-5 Energy Northwest/Columbia Generating Station

I and spiked TLDs that have been given a known exposure. Exposure received by the field TLDs during transport is monitored with a set of 'trip' control dosimeters that accompany the field dosimeters to and from the field locations and while they are in storage. Another set of TLDs, the building controls, are used to determine the exposure of the TLDs at the storage location. The TLD exposure during transport to and from the field was determined from the difference between the building control results 3 and the trip control results. 4.5.2 Gross Beta Activity on Air Particulate Filters 1 Air particulate filters are counted directly in a gas flow proportional counter after a delay of several days to allow for the decay of radon and its progeny. Samples were counted using a Protean WPC-9550 instrument which allows automated sample counting and simultaneous alpha/beta determination. If gross beta activity is identified at greater than 10 times the yearly mean of the control samples, gamma isotopic analysis is performed on the individual samples as required by ODCM Table 6.3.1-1 2c. 4.5.3 Measurement of Gamma Emitting Radionuclidesn Gamma isotopic analysis allows identification and quantification of gamma-emitting radionuclides that may be attributable to CGS effluents. Shielded, high purity germanium (HPGe) detectors are used to assay environmental samples for gamma emitting radionuclides. All samples are counted in' standardized, calibrated geometries.

  • Liquids - Measured aliquots of the liquid samples are poured into appropriately sized Marinelli beakers. Results are reported in pCi/liter.
    " Solids - Soil, sludge, and sediment samples are dried and if needed ground. Foodstuff, biota (fish), and vegetation, are chopped finely or pureed and then analyzed wet (no drying is done). For foodstuff (including fish), only the edible portion of the sample is used.

I Measured aliquots of the solid samples are placed into tared containers and weighed. Results i are reported in pCi/kg.

    " Charcoal Cartridges - Typically four charcoal cartridges are counted simultaneously using a cartridge holding jig that positions the cartridges in a standardized geometry to the side of the detector. Detector calibration files are maintained for both face mount and side count positions.

Sample volume for each cartridge group count is conservatively set to the lowest cartridge

  • sample volume in the group. If 1-131 is identified in the assay of a group, each charcoal cartridge in the group is assayed separately. Results are corrected for decay during the sample collection period. Results are reported in pCi/m 3.
  • Air Particulate Filters - At the end of each quarter, air particulate filters are composited on a station by station basis. The filters are stacked in a Petri dish and analyzed by gamma spectroscopy. Results are reported in pCi/mn 3 and represent the total quarterly gamma activity collected at each station. Results are decay corrected to the midpoint of the sample collection I

period. If a radionuclide related to CGS operation is positively identified, the filters are separated and counted individually. 2009 Annual Radiological Environmental Operating Report 4-6 Energy Northwest/Columbia Generating Station

                                                                                                                           ,I

4.5.4 Gross Alpha and Gross Beta Activity in Water A measured aliquot of each sample is evaporated to a small volume then quantitatively transferred to a ribbed, stainless steel planchet. Final evaporation is done under a heat lamp. Residue mass is determined by weighing the planchet before and after mounting the sample. The planchet is counted for alpha/beta activity using a Protean WPC-9550 automatic gas flow proportional counter which allows automated sample counting and simultaneous alpha/beta determination. Results are corrected for sample self-absorption using the sample residue mass values. Results are reported in pCi/liter. 4.5.5 Tritium in Water The sample is distilled, then 8.OmL of the distillate is mixed with 12.OmL of scintillation cocktail. The sample mixture is analyzed on a Packard Tri-Carb 2900TR automatic liquid scintillation counter. Results are reported in pCi/liter. 4.5.6 Sr-90, Fe-55 and Ni-63 in Water Shallow well water samples from the 1 st and 2 nd quarters were analyzed for these constituents by Teledyne Brown Radiological Laboratory Services using standard procedures developed by this vendor for these analyses. 4.5.7 Low Level Iodine-131 in Milk and Water Four liters of sample are first equilibrated with stable iodide carrier. Anion exchange resin is added to remove any iodine from the sample. The resin is isolated from the liquid sample and transferred to a small counting container. The iodine content is then determined by gamma spectroscopy analysis. Results are reported in pCi/liter. 4.6 Data Analysis Methods Counting results for low level samples are often within the counting error of the background determination; consequently results can range from negative to positive values in these samples. Though most REMP analytical results are below the detection limit, an actual calculated value has been reported. In some cases the reported value is zero or a negative number. Reporting results in this manner is a common practice in environmental analysis as it gives an indication of positive or negative biases that may be present and prevents loss of individual results inherent in the use of "less than" (<) values. Also reported in most cases are the a posterioriMDA values. A nuclide is flagged as positively identified if its calculated value is greater than the MDA. A listing of the Energy Northwest nominal target LLDs (a priori)for each sample type is provided in Table 4-4; the ODCM required LLDs are also included for a comparison. Data is trended following analysis for many of the sample types analyzed. For analyses such as gross beta on air particulate filters where results are normally above the detection limit, indicator results are plotted with the control results for easy comparison. Analysis results that are normally below detection limits are plotted against historical data to monitor if trends may be evident. Thermoluminescent dosimeter (TLD) data is presented in terms of the net mR/day exposure rate. These results are determined from the total exposure (in mR) calculated for each TLD minus the TLD background and any transit (or trip) exposure received during distribution and retrieval, and divided by the number of days the TLD was in the field. The total mR/standard quarter and mR/year values are 2009 Annual Radiological Environmental Operating Report 4-7 Energy Northwest/Columbia Generating Station

I also reported (see Tables 5-3, 5-4). All TLD results are reported in units of exposure (Roentgen) and I not in units of dose (Rem). The quarterly TLD results are compared with the annual TLD results and expressed as a ratio by I dividing the sum of the quarterly results over the annual results (See Appendix A, Table A- 1.1). The agreement between the two sets is usually within plus or minus ten percent (10%); occasionally fade can be more significant than expected in the annual set and the results may be lower than the sum of the 1 quarterly data. 4.7 Changes to the Sampling Program in 2009 I There were no major changes made to ODCM or EFSEC Resolution 260 mandated sampling in 2009. Sampling and analysis of shallow groundwater wells around CGS was made a routine part of the REMP. A new sample location near CGS was established (Station 103A) to provide vegetation i samples at CGS Chemistry Effluents request. A TLD location (Station 58) was added as part of the CGS effort to monitor remediation work at the DOE 618-11 burial ground. An annual sediment/sludge sample from the SWTF was not taken in 2009. The sample is not required by I EFSEC Resolution 300 and obtaining the sample presented health and safety concerns.

I TABLE 4-1 FOOTNOTES: (a) The fraction in parentheses for each sample type indicates the ratio of ODCM-required sample locations to the total number of sample locations currently being monitored in the surveillance program. Additional sampling is performed to meet EFSEC Resolution 260 requirements and at ENW initiative. I (b) The underlined sample location designates a control station. (c) Sample collection is performed at a frequency specified in the ODCM and EFSEC resolutions. Some sampling referenced in Table 4-1 is performed at CGS initiative. Sample deviations are permnitted if samples are unobtainable due to hazardous conditions, seasonal availability, malfunction of automatic sampling equipment, or other legitimate reasons. I (d) The ODCM specifies six air sample locations and EFSEC Resolution 260 specifies nine. Not listed in Table 4-1 are four other air sample locations established to monitor remediation work at the DOE 618-11 burial ground. See Section 5.9.6 for details. I (f) Sampling is performed to meet NEI 07-07 guidelines and NPDES requirements. (g) Soil samples are collected at five air-sampling locations to satisfy EFSEC Resolution 260 requirements. This resolution also requires Sr-90 analysis be performed on any indicator soil sample having gamma results greater than ten times the resultI for the control location. Cs-137 activity has historically been used as the gamma results parameter. (j) TLD Stations 71-86 are not included among the 34 TLD stations required by the ODCM. Alternate designations for these stations are IS- 16S. EFSEC Resolution 260 requires 25 or more TLD stations to be located within a 10-mile radius of CGS. (k) Pressurized ion chambers (PICs) may be used in place of or in addition to TLDs as per ODCM Table 6.3.1 -1 lb. (1) The term "river/drinking water" is used throughout this report because the drinking water is taken from the Columbia River. Station 26, CGS makeup water intake from the Columbia River is both an upstream water sample and the drinking water sample location. Station 29 is a downstream drinking water sample. The Station 27 sample, which is drawn from the plant discharge U line, is taken in place of a "downstream" water sample near but beyond the mixing zone. It reflects the radioactivity present in the plant discharge prior to any river dilution. EFSEC Resolution 260 requires two drinking water locations downstream from the plant discharge and requires sampling from the plant intake and discharge water. Only one drinking water station is now sampled after DOE closed the intake at the 300 Area (Station 28) in 1998. I (in) Composite samples are collected using automatic sampling equipment that collects an aliquot at time intervals that are short relative to the compositing period. I (n) A sediment sample from the SWTF has historically been taken annually, however there is no ODCM or EFSEC requirement to perform this sampling. No sediment was removed from the SWTW in 2009 and no sediment sample was collected or analyzed. (o) When the dose calculated via ODCM methodology for consumption of water exceeds I mrem per year, low level 1-131 analyses are performed on the drinking water samples. 3 (p) EFSEC Resolution 260 requires sampling from wells used for fire protection and as backup drinking water sources. (q) EFSEC Resolution 260 requires sediment sample collection upstream and downstream of the plant discharge. (r) Milk samples will be obtained from farms or individual milk animals that are located in the most prevalent wind directions from CGS. EFSEC Resolution 260 requires at least three milk locations within the 10-mile radius of the plant and one in a control location, however, ENW currently has access to only one dairy within a 10-mile radius of the plant (Station 36) and one control location at 30 miles. Broadleaf vegetation can be sampled in lieu of milk if a representative milk sample is not available. I (s) ODCM Table 6.3.1-1 4k requires that if Cs-i 34 or Cs- 137 is measured in an individual milk sample in excess of 30 pCi/I iter, then a Sr-90 analysis will also be performed. (t) Station 30 is the Columbia River and station 38 is the Snake River. If an impact is indicated, sampling will be conducted semiannually per ODCM Table 6.3.1-1 4i. There are no species fished commercially in the Hanford Reach of the Columbia River. The most recreationally important species in the area are anadromous, which ascend rivers from the ocean for breeding. Anadromous fish species are normally obtained from hatcheries; Snake River samples are obtained from the Lyons Ferry Fish Hatchery, and Columbia River samples are obtained at the Ringold Fish Hatchery. I (u) Garden produce is obtained from farms or gardens that use Columbia River water for irrigation. One sample of a root crop, leafy vegetable, and a fruit is collected each sample period, when available. The variety of the produce obtained will be dependent on seasonal availability. I (v) Station 91 is an apple orchard irrigated with Columbia River water that is normally sampled at harvest. Station 102G is a small garden/vegetation area located by the SWTF. Station 103A is a small park area located by the Kootanai building (EOF). Station 102G is maintained by REMP personnel and used to provide broad leaf vegetation samples, sampling at station 103A involves collection of broadleaf vegetation from trees and shrubs. Both stations are sampled at the request of CGS Chemistry effluents, neither station meets the ODCM criteria for a garden requiring sampling. 2009 Annual Radiological Environmental Operating Report 4-10 Energy Northwest/Columbia Generating Station I

5.0 RESULTS AND DISCUSSION 5.0 RESULTS AND DISCUSSION The Columbia Generating Station environmental TLDs were collected by Energy Northwest Environmental Services personnel and analyzed by Battelle at the Pacific Northwest National Laboratory (PNNL). Sr-90, Fe-55 and Ni-63 analysis were performed by Teledyne-Brown in Knoxville, TN. All other CGS REMP samples were analyzed by the Energy Northwest Environmental Services Laboratory located in Richland, WA. Table 5-2 provides a summary of the ODCM required REMP sample and CGS groundwater monitoring analysis results in the format specified in Regulatory Guide 4.8. Results for naturally occurring radionuclides that are not related to CGS operations have not been included in the summary table. The lower limits of detection (LLDs) listed in Table 5-2 are the ODCM required detection limits and are not the method detection limits listed in Table 4-4. Analytical results for all REMP samples are presented in Appendix A of this volume and summarize the results in greater detail. 5.1 Direct Radiation Direct radiation is monitored at 79 TLD locations surrounding CGS. TLDs are exchanged on a quarterly and annual frequency at all locations. The 16 locations designated as "S" stations are located between 0.3 and 0.8 miles from the CGS reactor building and all are inside the property boundary, see Figure 4-1 for station locations. Figure 5-1 presents the 2009 "S" station mean quarterly TLD results separated into sixteen geographical sectors around the plant. Figure 5-1 also shows the high, low, and mean result in each sector for 1984 through 2008 for comparison. The results in the N, NNE, and NNW sectors show higher exposure rates than most other "S" stations as a result of being physically closer to the ISFSI and the plant turbine building. The highest results were found in the NNW sector with this sector being the only one with results above the sector long term average. The NNW location is the closest "S" station to the ISFSI and higher results here are attributed to the stations close proximity to this facility. 0.36 _S-Stations 0.33 0.30 TTT E 0.27 E 0.24  :...O- - . . . ... .. ...

Exposure rates for 22 remote TLD locations are presented in Figure 5-3, see also Figure 4-3 for station locations. Station 46 in the Wahluke Reserve (NE sector) remained the remote location with the highest exposure rate. This has been the case since the preoperational measurement phase and is attributed to differences in the underlying rock and soil composition in this area. Remote location results for all sectors were below the preoperational and long term operational means. A similar pattern has been observed since 2003. The average deviation relative to the preoperational period was -5.3%. Offsite direct radiation monitoring results are consistent with previous years. The 2009 results indicate no measurable dose contribution due to plant operations at locations outside the CGS controlled area. Dose contributions inside the CGS controlled area are limited to those locations known to be influenced by the Independent Spent Fuel Storage Installation (ISFSI) and/or radiation from the turbine building during operation. Environmental radiation exposure rates for 2009, the preoperational phase, and the long term operational phase are summarized in Tables 5-3 and 5-4. See also Appendix A, Tables A-1.1 and B-1.1 for comparisons of the 2009 annual and summed quarterly TLD results. TLD results for special interest locations are discussed in further detail in Section 5.9. 5.2 Airborne Particulate/Iodine Air samples are collected weekly from 11 sample stations located around CGS. Additionally, an air sample station located 28 miles WSW of CGS is used as a control for comparison. Air particulate filters are analyzed for gross beta and iodine cartridges for radioactive iodines on a weekly basis. Air filters are also composited and analyzed for gamma emitting nuclides quarterly. The 2009 average particulate filter gross beta results for the five stations sampled weekly and located within three miles of CGS are plotted in Figure 5-4 (See also Appendix A, Tables A-2. 1, A-2.2). Results for these locations are within the range observed in previous years and closely follow the trend observed for the control location.

I Figure 5-5 is a plot of the 2009 mean weekly particulate filter gross beta results for the 6 sample I stations located between 3 and 9.6 miles from CGS (See also Appendix A, Tables A-2. 1, A-2.2). A similar trend to that seen with the near plant station was observed with all results trending closely to the control. A noticeable increase above the historic gross beta mean was observed in weeks 4, 8, I 11, and 50 at all locations including the control. These increases are attributed to weather induced background fluctuations. As noted in previously reports, gross beta levels typically increase during periods of inversion occurring in the fall and winter months. Gross beta results plotted over a period I of several years show a cyclical pattern of fall and winter increases. As the increases were seen at the control location also, the increases observed are due to background fluctuations and are not attributable to CGS operation.

5.3 Water 5.3.1 Surface Water Composite water samples are collected from 6 surface water locations monthly and analyzed for tritium, gross beta, and gamma emitters. A plot of the 2009 gross beta results for the plant intake, plant discharge, and river/drinking water are shown in Figure 5-6. All drinking and river water (Stations 26 and 29) gross beta results were below the analysis method a priori LLD (See Appendix A, Tables A-5. 1, A-5.2). Gross beta levels in the plant discharge water (Station 27) were higher than the levels seen in the intake water (Station 26). This is the normal observation as natural radioactivity is concentrated in the discharge water due to evaporative loss and the scrubbing action of the cooling towers which incorporates atmospheric particulate material into the water. The relatively low gross beta results for Station 27 during the summer months reflects periods when CGS was shut down for outages and discharge water was at a low level of concentration. The discharge sample results are representative of the radioactivity present in plant discharge water before any mixing with river water occurs.

(See Appendix A, Tables A-6. 1, A-6.2). This is consistent with results seen in previous years. Tritium results for the three sample locations are plotted in Figure 5-7. Gamma spectroscopy results for all plant intake, plant discharge, and river/drinking samples showed no indication of any gamma-emitting radionuclides of interest being present (See Appendix A, Tables A-7. 1, A-7.2). There is no evidence of significant impact to the environment due to CGS plant operations in the plant intake, plant discharge, or river/drinking water results analyzed in 2009. Composite water samples are also taken from two sanitary waste sample locations and one storm drain location. Analysis results for these samples are discussed in further detail in Section 5.9.

Routine quarterly sample collection from eleven shallow groundwater monitoring 3 wells located near CGS was also performed in 2009 as part of the CGS groundwater monitoring program. During the 1 st and 2 nd quarters of 2009, the shallow ground water samples were analyzed for tritium, gross alpha/beta, gamma emitters, Sr-90, Fe-55 and Ni-63. During the 3rd and 4th quarters, these samples were analyzed for tritium and gamma emitters. Locations of the ground water wells are shown in Figures 4-1 and 4-2. Analytical results for the three deep water wells were consistent with results seen in previous years. No gamma emitting radionuclides of interest or tritium was identified in any of these samples (See Appendix A, Tables A-6.1, A-6.2, A-7.1, and A-7.2). 3 Analytical results for the eleven shallow monitoring wells are presented in Table 5-2 and Appendix A. Gamma Spectroscopy results for these samples did not identify any gamma emitting radionuclides of interest (See Appendix A, Tables B-10.1, and B-10.2). Results of the Sr-90, Fe-55 and Ni-63 analyses conducted during the 1 st and 2 nd quarters were all below the analysis methods minimum detectable concentration (See Appendix A, Table B-9. 1). Results from the gross alpha/ beta analysis conducted during the 1st and 2 nd quarter showed the presence of small quantities of gross alpha and beta present in most of these samples (See Appendix A, I Table B-12.1). Tritium concentrations in these samples ranged from < LLD to 17,000 pCi/liter (See Appendix A, Table B- 11.1). Tritium results from each well were consistent during the year with the exception of well 7 results in the 2nd quarter and well 8 results during the 3d quarter which were noticeably above the trend.

The eleven shallow wells allow water to be sampled from the unconfined aquifer around the CGS site. None of these monitoring wells are used as a source of drinking water. CGS is unique in the commercial nuclear power industry in that it is located in an area where the unconfined aquifer under the site is known to be contaminated with tritium as a result of past DOE activities on the Hanford Site(20 ). The CGS groundwater program is intended to assess any contribution CGS may be making to the known groundwater contamination issue. 5.4 Soil Gamma spectroscopy analysis was performed on soil samples from 5 different locations in 2009 (See Appendix A, Tables A-8. 1, A-8.2). Naturally occurring radionuclides ( K-40 and Bi-214) were identified in all samples and Cs- 137 was identified in two of the samples, one being a sample from the control location. The level of Cs-137 identified was similar to that seen in the past and within the concentration range that is considered normal background levels for Hanford site soils.!.') No indicator location had Cs-137 concentrations high enough above the control location to require Sr-90 analysis. The soil sample results do not indicate any measurable impact from CGS plant operation. 5.5 River Sediment Gamma assays of river sediment identified naturally occurring radionuclides (K-40, Ra-226, Bi-214) and Cs- 137 (See Appendix A, Tables A-9.1, 9.2). Cs- 137 was detected in one upstream (Station 33) and both downstream (Station 34) samples (relative to the cooling tower discharge point). As observed in previous years, Cs-137 downstream activity was slightly higher than the activity identified upstream. Both the upstream and downstream Cs- 137 activity levels identified are within the range quantified in previous years and consistent with known Cs- 137 background levels in Hanford area sediment and soil] 19). The sediment sample results do not indicate any measurable impact from CGS plant operation. CGS has not made a radioactive discharge to the Columbia River since 1998. 5.6 Fish The gamma spectroscopy results of fish samples collected at both the indicator location (Columbia River) and the control location (Snake River) identified the presence of only naturally occurring radionuclides. (See Appendix A, Tables A-10.1, 10.2). These results are consistent with results seen from past years. 2009 Annual Radiological Environmental Operating Report 5-7 Energy Northwest/Columbia Generating Station

I I 5.7 Milk There was no 1-131 activity identified in any of the milk samples collected in 2009 (See Appendix A, Tables A- 11.1, A- 11.2). Gamma spectroscopy results of milk radionuclides other than 1-131 did not identify the presence of any radionuclides of interest above detection limits (See Appendix A, i Tables A-12.1, A-12.2). Naturally occurring K-40 was identified in all milk samples. I 5.8 Garden Produce Gamma analysis was performed on twelve different fruit and vegetable crops in 2009 (See I Appendix A, Tables A- 15.1, A- 15.2, A- 16. l, A- 16.2, A- 17.1, A- 17.2). No radionuclides of interest were identified in any of the samples. Naturally occurring K-40 was identified in all samples. 3 5.9 Special Interest Stations 3 Sampling and analysis is performed at the locations covered in this section to comply with EFSEC requirements or is performed at CGS initiative. The storm drain pond and the Sanitary Waste Treatment Facility (SWTF) were incorporated into the routine sampling schedule in 1992. In 1995, I the cooling tower sediment disposal area was added. TLDs were placed around the spray pond drain field (Station 120) in June 1995. TLD monitoring in the vicinity of the planned Independent Spent Fuel Storage Installation (ISFSI) was first performed in 1998 to collect background data and I TLD monitoring was established on the ISFSI fence line after construction was completed in 2002. Discussions of the results from each of the locations are given in the following sections. I 5.9.1 Storm Drain Pond (Station 101) The storm drain pond (NPDES Outfall 002) is located approximately 1500 feet northeast of CGS. Water is sent to the pond through an 18-inch diameter pipe that discharges into a 300-foot long earthen channel that leads to a 100-foot diameter pond. The pond is a shallow, unlined percolation/evaporation basin. Water at the storm drain outfall is sampled using a flow proportional automatic sampler to collect monthly composite samples. The storm drain pond area is fenced and access is restricted. Monthly water samples were analyzed for gamma emitting radionuclides, tritium, and gross beta. Gamma spectroscopy results did not identify the presence of any gamma emitting radionuclides of interest (See Appendix A Tables B-2.1, B-2.2). Gross beta was positively identified in only one of the twelve samples; the level identified was just above the detection limit and within the range observed in previous years. (See Appendix A, Tables B-3.1, B-3.2). Tritium was detected in six of the twelve samples (See Appendix A, Tables B-4.1, B-4.2). The samples with the highest tritium activity were from colder, wetter months which is consistent with results seen in previous years. The source of the tritium in these samples is believed to be from recapture of tritium from CGS effluents which is more likely to occur during cooler, rainier periods. Multiple Station 101 2009 Annual Radiological Environmental Operating Report 5-8 Energy Northwest/Columbia Generating Station i I

composite samples were analyzed in July. Emergent condenser repair work resulted in CGS discharging large amounts of water via this pathway during this time frame. 5.9.2 Sanitary Waste Treatment Facility (Station 102) The Sanitary Waste Treatment Facility (SWTF) is located approximately 0.5 miles south-southeast of the CGS. The facility processes sanitary waste water from CGS, the ENW Industrial Development Complex (formerly referred to as WNP-1 and WNP-4), the Kootenai Building, and the DOE 400 Area. Station 102B receives water from all these locations, Station 102A receives water only from the DOE 400 Area. Discharge standards and monitoring requirements for the SWTF are established in EFSEC Resolution No. 300(5). The monthly composite gross alpha and beta results for the DOE 400 Area effluent (Station 102A) and the SWTF head works (Station 102B) were consistent with results seen in previous years. Low level gross beta was identified in all samples, gross alpha was not identified above the LLD in any of the samples. (See Appendix A, Tables B-5.1, B-5.2, B-6.1, B-6.2). Gamma spectroscopy results of the monthly SWTF water samples identified 1-131 in the January Station 102B composite sample. AR/CR 192102 was written to document the finding. As no additional radioisotopes were identified in the sample, the determination was made that the source of the radioiodine was from a medically administered treatment. No other gamma emitting radionuclides of interest were detected in any of the other samples analyzed in 2009 (See Appendix A, Tables B-7.1, B-7.2). A Station 102D sediment sample (collected from the lined north stabilization pond) was not collected in 2009. Tritium activity was identified in most all of the SWTF Station 102A and 102B samples (See Appendix A, Tables B-8. 1, B-8.2). The tritium levels identified are consistent with levels identified in previous years. Station 102A results remain elevated as the source of this sample is partly from an unconfined aquifer that is known to be contaminated with tritium as a result of past DOE activities on the Hanford site(20 ). Tritium activity coming from the DOE 400 area is the main source of the tritium identified in the station 102B samples. 5.9.3 Cooling Tower Sediment Disposal Area (Station 119) EFSEC Resolution No. 299(16) authorizes the onsite disposal of sediments from plant cooling systems containing low levels of radionuclides. The disposal area for these sediments is located just south of the cooling towers. Resolution No. 299(16) requires direct radiation monitoring using quarterly and annual TLDs in the vicinity of the disposal cells and the collection and analysis of a dry composite sediment sample from the disposal cell within thirty days following each cleaning to confirm that the disposal criteria outlined in the resolution have not been exceeded. Cleaning of the cooling towers was performed in May 2009. Disposal of the material removed resulted in an estimated 131.6 cubic meters of dry sediment being placed into the 2007 disposal cell. In April, an estimated 4 cubic meters of dry material removed from Valve boxes 9 and 12 was placed into the 2005 disposal cell. Approval for this disposal was given by EFSEC. Figure 5-8 summarizes the estimated quantity of radionuclides that were placed in the disposal area in 2009. For those isotopes listed in the table that were not positively identified, the MDA value obtained 2009 Annual Radiological Environmental Operating Report 5-9 Energy Northwest/Columbia Generating Station

I from the sample analysis was used in the table calculations. As such, the total activity reported I should be considered a conservative estimate. All results are well below the disposal concentration limits specified in EFSEC resolution 299(16). I Cs-137 is routinely identified in the sediment disposal samples and the CS-137 level identified in the 2009 samples were within the range seen in previous years and only slightly higher that the Cs-137 levels identified in Columbia River sediment (See Appendix A, Tables A-9.1 for comparison). I Co-60 was not positively identified in any 2009 sample.

3.88E-05 Figure 5-8 Cooling Tower Sediment Activity Levels For Disposals Made In 2009 I Measurements of direct radiation at the disposal basin was taken using TLDs. Two locations were used, an indicator location next to the collection area (Station 119B) and a control location I approximately 100 yards to the east (Station 119C). The mean quarterly and annual TLD results agree well with results from previous operational years. The negligible difference between the indicator and the control TLDs indicate that there was no measureable dose contribution above I background due to material in the disposal cells. (See Tables 5.3, 5.4 and Appendix A, Tables B-

1. 1, 13-1.2). I 5.9.4 Spray Pond Drain Field (Station 120)

There were no discharges to the Spray Pond Drain Field (NPDES Outfall 003) in 2009. The TLD I results at Station 120 in 2009 are in agreement with those seen in previous operational years (See Table 5-3, 5-4 and Appendix A, Tables B- 1.1, B- 1.2). I 5.9.5 Independent Spent Fuel Storage Installation The Independent Spent Fuel Storage Installation (ISFSI) is a fenced, secured area north northwest i of CGS. Ten TLD stations, stations 123,-129 and stations 136A-138A are located on the outer security fence surrounding the ISFSI. TLD station 122 is just north of the ISFSI between the ISFSI and the plant access road. TLD station 121 is located approximately 0.1 mile north of the I plant between the Transformer Yard and the ISFSI. Refer to Figure 4-4 for ISFSI TLD locations. I 2009 Annual Radiological Environmental Operating Report 5-10 Energy Northwest/Columbia Generating Station I

Radiological exposure rates at the ISFSI security fence are elevated and access to the area directly outside the fence requires radiological dosimetry and security notification to enter. In addition to the TLD monitoring program, quarterly radiological surveys of the ISFSI are conducted by the CGS Radiation Protection Department. No spent fuel storage casks were added to the ISFSI during 2009. As shown in Figure 5-9, exposure rates at the ISFSI fence line followed a leveling to downward trend during the year. Station 122 TLD results showed a similar pattern with the trend for this location correlating to the overall ISFSI TLD trend but at a lower level. The Station 121 TLD results showed a marked drop in the second and third quarters reflecting plant operational status. As noted in previous reports, the trend for this location is more influenced by turbine building radiation levels than by the ISFSI.

5.9.6 Additional Air Sample and TLD Locations Four additional air sample locations (Stations 87-90) and 5 TLD stations (Stations 58, 87-90) were established in 2008/2009 in order to monitor air quality and direct radiation during remediation work at the DOE 618-11 burial ground located just west of CGS (See Figure 4-1). Air samples were collected and TLDs were exchanged at these locations in 2009 though no remediation work took place at the burial ground during the year. Air particulate data from the four locations show no indication of any effects from CGS effluents (See Appendix A, Tables B-13.1 and B-14.1). Three of the TLD stations had results slightly higher than background due to the stations close proximity to the turbine building and the ISFSI (See Appendix A, Table B-I. 1).

6.0 QUALITY ASSURANCE AND QUALITY CONTROL 6.0 OUALITY ASSURANCE AND OUALITY CONTROL The REMP is designed to meet the quality assurance (QA) and quality control (QC) criteria of the NRC Regulatory Guide 4.15(4) and 10 CFR 50 Appendix B(10 ). The contractors used for sample analysis, Energy Northwest Environmental Services and Battelle PNNL, maintain quality control programs to ensure that analytical results are accurate, precise, and defensible. The following sections summarize the quality assurance and quality control aspects of the TLD, sample collection, and sample analysis components of the REMP. 6.1 Quality Control for the Energy Northwest Environmental TLD Program The Quality Control program for the Energy Northwest REMP TLDs covers the preparation, transportation, deployment, collection, storage, processing, and evaluation. From the time the TLDs are annealed to the time they are placed in the field, they are stored and transported with control TLDs. Two sets of control TLDs are used, the building controls and the transportation (trip) controls. The building controls monitor the exposure that the TLDs receive while being transported to and from the TLD vendor and while in storage awaiting deployment and analysis. The trip controls accompany the field TLD set while they are being transported to and from the vendor and also while they are being deployed and collected in the field. The building controls and trip controls are stored in a low background lead shield while the field TLDs are deployed, If the trip control results are greater than the building control results, the difference between the two is subtracted from the field dosimeters to account for exposure during transit. Reader QC dosimeters are prepared by Battelle at the Pacific Northwest National Laboratory and serve as indicators that the reader calibration is satisfactory and that the TLDs were processed correctly.. These TLDs are annealed and then given a known exposure (typically 100 mR) to a cesium-137 source. The number of QC dosimeters used during each processing is generally 10% of the number of field dosimeters. Evaluation of the 2009 reader QC dosimeter results indicated satisfactory agreement for all periods. The average reader QC results are presented in Table 6-1. TLDs designated as spikes are prepared by the Energy Northwest Radiation Protection Department by exposing the TLDs to a calibrated source to produce a known exposure. The spiked dosimeters are submitted and processed with the field dosimeters to further verify the accuracy and precision of the environmental TLD results. Quarterly spikes receive a target exposure of 22 mR and annual spikes receive a target exposure of 88 mR. Additional spiked TLDs were prepared in the I1t and 2 nd quarters to test the calibrated source mechanism at different exposure times and distances. Evaluation of the 2009 spiked dosimeter results indicated satisfactory agreement for all periods. Spiked TLD results are presented in Table 6-1. 6.2 Quality Control for the Environmental Sample Program Quality control for the environmental sample program encompasses both the sample collection and sample analysis processes. Results are reviewed for correctness, reasonableness, and data entry errors. Sample results that are suspect are normally investigated. A crosscheck program utilizing blind samples supplied by an outside vendor is maintained for all the sample media routinely analyzed. 2009 Annual Radiological Environmental Operating Report 6-1 Energy Northwest/Columbia Generating Station

I I 6.2.1 Sample Collection Quality Control Duplicate samples are collected and submitted for analysis when practical. The duplicate samples i are used to assess the repeatability of the sample collection process and the precision of the analytical method. 6.2.2 Laboratory Instruments Quality Control Analytical Balances - Analytical balances used in the laboratory for sample preparations are calibrated every six months. Performance checks are performed prior to use and span the range of intended use. Performance check results are documented on the sample preparation forms and I are kept with the analytical results. i Analytical Instruments - Analytical instruments used for determining radioactive emissions in samples are calibrated for efficiency annually using standard reference material traceable to the National Institute of Standards and Technology (NIST). Below is a summary of the routine QC B practices for the different analytical instruments.

  • Gas-flow Proportional Counter: QC and background checks are performed daily when in use. Control charts are maintained with two and three-sigma limits specified; the checks 3

must fall within the two-sigma warning limits prior to use. Mid batch and end of batch performance checks are normally performed. Gamma Spectrometers: Checked daily for efficiency, energy per channel relationship, I peak resolution, and background when in use. The checks are performed and plotted for both a low and high energy peak. Efficiency checks are held within two-sigma control limits. Long duration background checks are performed periodically.

  • Liquid Scintillation Counter: Background and performance checks are performed daily when in use. A QC check in the same matrix as the samples is performed and trended. A low level check standard is analyzed with each batch of samples analyzed.

I 6.2.3 Sample Batch Quality Control I Sample batch analysis is normally performed with sample blanks and known-addition samples (or spiked samples) included. The type of known addition sample used is dictated by the sample media being analyzed, the primary analytes of interest, and the method being used. The following is a summary of sample batch QC activities. i Iodine-131 Cartridges - At least one known-addition sample was analyzed with each batch. In most cases, a charcoal cartridge of the same type used for sample collection but spiked with Ba-133 is used. The 356 keV peak of Ba- 133 serves as a proxy for the 364 keV peak of 1-131. Gross Beta Filters - At least one unused blank air particulate filter and at least one known-addition air particulate filter was analyzed with each batch. i Aqueous Samples - In most cases, samples collected from the control locations were analyzed as blanks. A known-addition sample was analyzed with each batch of samples. 3 2009 Annual Radiological Environmental Operating Report 6-2 Energy Northwest/Coiu mbia Generating Station I

Gross Alpha/Beta in Water - Blank Samples were prepared from reagent grade water and analyzed with each batch of samples. One known addition sample and one replicate sample is normally analyzed with each batch. Tritium in Water - A blank and a low level known addition sample are typically analyzed with each batch. A replicate sample was prepared and analyzed inside of each batch in most cases. 6.3 Laboratory Intercomparison Program Participation and Results Participation in cross check intercomparison studies is mandatory for laboratories performing analyses of CGS REMP samples. Intercomparison studies provide a consistent and effective means to evaluate the accuracy and precision of analyses performed by a laboratory. Study results should fall within specified control limits, results that fall outside the control limits should be investigated and corrective action taken. The Energy Northwest Environmental Services Laboratory participated in both RAD and MRAD proficiency testing studies provided by Environmental Resource Associates (ERA) during 2009. The Laboratories intercomparision program was further supplemented by additional cross check media provided by Analytics, Inc. The Laboratories intercomparison program results for 2009 are shown in Table 6-2; results for all media and analytes tested were acceptable. Participation in the ERA and Analytics studies serves to meet the intercomparision program requirements specified in the ODCM. The Laboratory did not participate in a MAPEP study during 2009. In addition to the studies noted above, the CGS REMP maintains a split sample program with the State of Washington Department of Health. Split samples are sent to a State of Washington Lab on a scheduled frequency where they are independently analyzed. This program provides an additional check on the accuracy and precision of the results reported in this document. 2009 Annual Radiological Environmental Operating Report 6-3 Energy Northwest/Columbia Generating Station

FORWARD Since mid-1984, the results of the REMP analyses have been presented as net results calculated from total counts minus the observed background counts of the detection method. Counting results for low level samples are often within the counting error of the background determination; consequently results can range from negative to positive values in these samples. Though most of the analytical results presented in this Appendix are below the detection limit, listing the actual calculated value, even when it is negative or below the detection limit, prevents positive biases and loss of individual results inherent in the use of "less than" (<) values. It is standard practice to report radiological environmental data in this manner. Most results listed in this Appendix are accompanied by a plus or minus (+/-) error value. In most cases the error value represents the two sigma counting uncertainty determined for that particular analysis. These error values are in the same units as the listed activity values. The two sigma error value represents the range that a recount of the same sample would be expect to fall within 95% of the time, based on the statistics encountered in the original count. Also included in most case are the analysis specific, minimum detectable activity (MDA) values. Though similar in concept to the LLD, these values are based on the statistics encountered in the specific sample count itself and not a blank determination. As such, they are a a posteriori (after the fact) determination where the LLD is a a priori(before the fact) determination. These values were included as they represent the level of activity that would have needed to be present in the sample for a positive identification to be made. iii
