SUMMARY

1.0 EXECUTIVE

SUMMARY

The primary 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 (NEI) guidelines or as an Energy Northwest initiative. The program also serves to validate CGS effluent measurements and exposure pathway models and to provide a documented, historical record of CGS impact on the environment. This report serves to document and communicate the program results and findings for calendar year 2013.

A variety of environmental samples are routinely collected and analyzed by the REMP. The types of samples collected include air, water, soil, sediment, milk, fish, and garden produce. Additionally, the program continuously monitors direct radiation at numerous locations surrounding CGS. 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 in 2013 had minimal radiological impact on the environment. The only identified radiological impact to areas outside the CGS controlled area consisted of low level tritium in one plant discharge water sample that is attributed to recapture of CGS gaseous effluent tritium. All other identified radiological impact was limited to areas within the CGS controlled area. 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.

With the exception of the one tritium sample result, all radioactive material identified outside the CGS controlled area was of natural origin or known to be present in the environment around CGS in the quantities identified. The results are consistent with and verify CGS effluent measurements and modeling of the exposure pathways.

Below is a summary of the 2013 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 due to CGS operation was identified. The radionuclide activity identified in soil samples were consistent with activity levels known to exist in Hanford area soils.

Waterborne - No significant impact was identified. Low level tritium was identified in storm drain water and radionuclides related to CGS operation were identified in storm drain soil and cooling system sediment. Low level tritium was identified in one plant discharge water sample. All activity identified at these locations is attributed to recapture of CGS effluents. The 2013 data supports the longer term observation that storm drain tritium may be influencing groundwater tritium at locations near the storm drain pond. Tritium identified in sanitary waste water is attributed to discharges made from facilities operated by the Department of Energy. Tritium activity identified in groundwater was 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

3.1 Site Description The Columbia Generating Station (CGS) is a 1230 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) 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 potassium-40, beryllium-7, actinium-228 (present as a decay product of radium-228), and radium-226. Additionally, some relatively long lived anthropogenic radioisotopes, such as strontium-90 and cesium-137, are also seen in some REMP samples; these radionuclides exist in measurable quantities 12 throughout the world as a result of fallout from atmospheric nuclear weapons testing. ' 3)

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) 4.8,(5) and the Radiological Assessment Branch Technical Position. 61 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(71 and 4.13.(8) The REMP also adheres to the requirements of the Washington Energy Facility Site Evaluation Council,(9 ) the Columbia Generating Station Technical Specifications,(10 .)and the Offsite Dose Calculation Manual"1 1 ) 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 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.

I The Energy Northwest Environmental Services Laboratory performed all routine REMP sampling and analyses in 2013. Thermoluminescent dosimeters (TLDs) used in the REMP were processed by U

the Hanford External Dosimetry Program (HEDP) operated by Mission Support Alliance (MSA).

In addition to evaluating the environmental concentrations against regulatory limits, the REMP may I

also compare results to state standards.1 12. 13) The results may also be evaluated by comparing them 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 I

The REMP provides an independent mechanism for determining the levels of radioactivity in the plant environs in order to empirically quantify and qualify any radiological effect plant operation may be making on the environment. The program serves to ensure that any accumulation of I radionuclides in the environment resulting from station operation will be identified promptly and before they become significant or exceed established limits.

While in-plant monitoring programs are used to ensure that 10 CFR 20(14) and 10 CFR 50(15) criteria I

for releases of radioactive effluents are met, the REMP further verifies that the measured concentrations of radioactive material and levels of radiation observed in the environment are not higher than expected based on CGS effluent measurements and modeling of the exposure pathways.

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 ten 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 one 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 four 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. Three security fences surround the ISFSI facility.

Direct radiation monitoring of the ISFSI is performed using TLDs placed at 10 different locations on the second of three security fences that surround the facility. The TLDs are exchanged quarterly. 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.

I 4.3: Land Use Census I A land use census covering the areas within a five mile radius of CGS is performed annually. The objective of the land 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 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 I

results of the 2013 five miles land use census are presented in Table 4-3. No significant changes from the 2012 land use census were observed.

4.4 Sampling Methods 3 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. All routine REMP samples collected in 2013 were prepared for analysis at the Energy Northwest Environmental Services Laboratory located in Richland, WA. The section 4.4 subsections I

below give a general overview of the sampling methods used in the REMP. Generic descriptions of the REMP sample analysis methods are given in section 4.5. I 4.4.1 Direct Radiation Direct radiation dose levels are monitored with Harshaw Model 8807 thermoluminescent dosimeters (TLDs). The TLDs are placed in the field between three and five feet above the ground. TLDs are wrapped in aluminum foil and sealed in plastic bags to prevent damage. TLDs are exchanged on a quarterly basis.

The locations of the TLD stations are listed in Table 4-2 and are shown in Figures 4-1 through 4-4.

Station 9A near Sunnyside, WA serves as the environmental TLD control location. Station 11 9C serves as the control for Station 119B (the cooling system sediment disposal basin). The remaining TLDs deployed in the field serve as indicator TLDs. U The TLDs are arranged in a series of rings that encircle CGS. The innermost ring of TLD stations, referred to as the "S" stations, are located inside the CGS site boundary at distances that range from 0.3-0.8 miles from the reactor building centerline. The second ring of TLDs, referred to as the "near plant" I 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 ten miles. A MicroRem dose rate meter is available as a backup device and to take real time readings as needed.

4.4.2 Airborne - Particulate/Iodine Weekly air particulate and radioiodine (Iodine -131) samples are obtained through the use of low volume (1.5 cfm), constant flow-rate sampling units located at 1.2 locations. The samples collected at Station 9A (Figure 4-3) serve as controls, the samples collected at all other locations (Figures 4-1, 4-2, and 4-3) are indicators. Air particulate samples are collected using 47mm diameter glass fiber filters, air iodine 3

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 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 4-2 U

2013 Annual Radiological Environmental Operating Report Energy Northwest/Columbia Generating Station

additional air sample monitor locations are available to monitor work at the DOE 618-11 burial site if needed.

4.4.3 Water Water sampling is performed to meet ODCM and State of Washington EFSEC requirements, comply with NEI guidelines, or as 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; ten locations (MW-3, 5, 6 and MW-8 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 City of 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 on Energy Northwest property are used to provide deep groundwater samples. These wells are greater than 400 feet deep and provide samples from the confined aquifer.

under CGS. Station 52 is a deep well located 0.1 mile north of the CGS reactor building. Station 31 and 32 are deep wells at the IDC (ENW Industrial Development Complex) 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 sources of water to the pond are discharges from the potable water and plant makeup water demineralizer treatment systems. Storm water runoff from the CGS site is also directed to this location. Water discharges from CGS that have been verified to meet radiological environmental discharge limits are another potential source of water to the storm drain pond. Water is collected monthly using a flow-proportional composite sampler and analyzed for gross beta, gamma emitting radionuclides, and tritium.

The Sanitary Waste Treatment Facility (SWTF) receives sanitary waste water from CGS, the IDC (ENW I Industrial Development Complex), the Kootenai Building, and the DOE 400 area. Discharge standards and monitoring requirements for the SWTF are established in EFSEC ResolutionNo. 300. (16) Station 102A is a flow meter and composite sampler located on the DOE 400 area sewer line before it ties into the sewer lines coming from Energy Northwest facilities. Water used at the DOE 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 concentrations normally around 1500-3 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. Monthly samples are collected at both 3

Stations 102A and 102B and analyzed for gross alpha, gross beta, tritium, and gamma emitting radionuclides.

Routine quarterly grab samples are taken as part of the REMP from 10 shallow groundwater monitoring wells surrounding CGS. The monitoring well locations are shown in Figure 4-1. The shallow groundwater wells are all less than 100 feet deep and allow samples to be obtained from the unconfined I

aquifer under CGS. None of the wells are used for drinking water. Sampling from these locations is performed to meet NEI 07-07 guidelines (17) and requirements in the CGS NPDES permit.

4.4.4 Soil I Annual soil samples are a requirement of EFSEC Resolution No. 332.(9) For 2013, two soil samples were collected from locations near CGS, two samples from farmland in Franklin County east of CGS, and one sample from a control location near Sunnyside, WA. Each sample was collected from an area of I approximately one square foot to a depth of approximately one inch. About two kilograms of soil was collected for each sample. Soil samples are analyzed for gamma activity on a dry weight basis.

4.4.5 Sediment River sediment samples are collected semiannually as required by the ODCM and EFSEC Resolution No. 332.(9) 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 shallow surface sediment scooped from areas known to be underwater during high water periods and where the potential for sediment accumulation is likely. Sediment samples are dried in an oven and then analyzed for gamma emitting radionuclides on a dry weight basis.

Cooling system sediment samples are collected and analyzed whenever cooling system sediment is added to the disposal cells (Station 1 19B, Figure 4-1). Disposal of cooling system sediment is made in accordance with EFSEC Resolution No. 299.(18) Pre-disposal samples are collected and analyzed prior to ,

transfer to ensure the material will be within the limits specified in the EFSEC resolution. Following transfer, the material is allowed to dry and a post-disposal sample is collected and analyzed. 3 4.4.6 Fish Annual fish sampling is usually performed in the fall. Fish samples collected from the Columbia River (Station 30) serve as indicator samples, whereas fish collected on the Snake River (Station 38) serve as 3

control samples. Only edible portions of the fish are used to prepare the samples for analysis. Fish 2013 Annual Radiological Environmental Operating Report 4-4 Energy Northwest/Columbia Generating Station I

samples are analyzed for gamma emitting radionuclides on a wet weight basis. Three species of fish are collected; an anadromous species (salmon or steelhead), and two other species generally considered edible or potentially edible (typically carp, catfish, sucker, or whitefish). The same species are collected at each location. Electroshock techniques have historically been used for 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 more 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 2013 from two locations. Station 36 in Franklin County serves as the indicator location and is the only known dairy within a ten mile radius of CGS. Station 9B near Sunnyside, WA 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. Three types of garden produce are typically collected; root crops, fruits, and leafy vegetables. Control samples (Station 9C) are usually obtained from the lower Yakima Valley. Indicator samples (Station 37) are primarily collected from areas downstream of the CGS discharge where crops are irrigated with Columbia River water. The Riverview area of Pasco is the principle collection location for fruit and root crops. Collection of leafy vegetables is primarly made from locations that could potentially be influenced by CGS gaseous emissions. Vegetation samples may also be collected from locations closer to CGS; however none were collected in 2013. Garden and vegetable samples are typically purded 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. All REMP TLDs in 2013 were processed by Mission Support Alliance (MSA) at the Hanford External Dosimetry Program (HEDP) facility located in Richland, WA. All routine REMP field samples were collected and analyzed by Energy Northwest Environmental Services personnel. 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 lists the ODCM required LLDs and the nominal target LLD used in the Energy Northwest REMP program.

4.5.1 Analysis of TLDs REMP TLDs are analyzed 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 cesium- 137 source. Each group of environmental TLDs is processed with blank (freshly annealed) TLDs 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.

2013 Annual Radiological Environmental Operating Report 4-5 Energy Northwest/Columbia Generating Station

I Another set of TLDs, the building controls, are used to determine~the exposure of the TLDs at the storage I location. The TLD exposure during transport to and from the field was determined from the difference between the building control results and the trip control results. i 4.5.2 Gross Beta Activity on Air Particulate Filters 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 significantly above the mean of the control, gamma isotopic analysis is performed on the individual samples.

I 4.5.3 Measurement of Gamma Emitting Radionuclides 3 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 j 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 I Marinelli beakers or plastic canisters. Sample results are corrected for decay during the collection period if applicable. Results are reported in pCi/liter. I

" 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. Sample aliquots are placed in tared containers and weighed. Results 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 count and side count positions. If radioiodines are 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 I

reported in pCi/m 3 . 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/m 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. I 4.5.4 Gross Alpha and Gross Beta Activity in Water g A measured aliquot of each sample is evaporated to a small volume then quantitatively transferred to a ribbed, stainless steel planchet. Final evaporation is normally done under a heat lamp. Residue mass is determined by weighing the planchet before and after mounting the sample. The planchet is counted for gross alpha and beta activity using a Protean WPC-9550 automatic gas flow proportional 3

counter which allows automated sample counting and simultaneous alpha/beta determination. Results 2013 Annual Radiological Environmental Operating Report 4-6 Energy Northwest/Columbia Generating Station l

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 8.0mL 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 Strontium-89/90, Iron-55, and Nickel-63 These "hard to detect" analytes are not routinely analyzed as part of the CGS REMP. When needed, these analyses are performed under contract by Teledyne- Brown Environmental Services Laboratory located in Knoxville, TN using the vendor's standard analysis procedures.

4.5.7 Low Level Radioiodine in Milk and Water Four liters of sample are first equilibrated with stable iodide carrier. Anion exchange resin is then added and mixed for a period sufficient to allow any iodine present in the sample to be captured by the resin.

The resin is then isolated from the liquid sample and transferred to a small counting container. The radioiodine content is 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. for these samples can be positive or negative values. Though most REMP analytical results are belowthe 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 the preferred practice for low level environmental analyses 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 aposterioriMDA values. Anuclide is flagged as positively identified if its calculated value is greater than the MDA. A listing of the Energy Northwest nominal target LLDs (apriori)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 better 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 both units of mR/day and mR/standard quarter.

TLD results in mR/day are calculated by taking the total exposure (in mR) determined for each TLD, correcting for storage background and any transit (or trip) exposure received during distribution and retrieval, then dividing by the number of days the TLD was in the field. The mR/standard quarter values are calculated by multiplying the mR/day value by 91.25 days (365/4). All TLD results are reported in units of exposure (Roentgen) and not in units of dose (Rem).

I 4.7 Changes to the Sampling Program in 2013 i

There were no major changes made to ODCM or EFSEC Resolution No. 332(9) mandated sampling in 2013. Sampling and analysis of shallow groundwater wells around CGS was continued as a routine I

part of the REMP. No samples were obtained from one of the shallow groundwater wells (MW-7) in 2013 due to lack of water. The last sample obtained from this location was in the third quarter 2012.

Sampling -from Station 102A was terminated at the end of December. This station consisted of a i

composite water sampler that sampled the sanitary effluent line coming from the DOE 400 area. The effluent line was plugged in mid-December and ENW is no longer accepting sanitary waste from this location. One TLD location, Station 73, was moved in October to a new location due to construction activities. The new location is in the same geographical sector and approximately 175 feet from the old location. I i

I TABLE 4-1 FOOTNOTES:

(a) -The fraction in parentheses for each sample type indicates the ratio of ODCM-required sample locations tothe total number of sample locations currently being monitored in the surveillance program. Additional sampling is perforimed to meet EFSEC Resolution 332 requirements or as an ENW initiative.

(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 permitted if samples are unobtainable due to hazardous 5

conditions, seasonal availability, malfunction of automatic sampling equipment, or other legitimate reasons.

(d) The ODCM specifies six air sample locations and EFSEC Resolution 332 specifies nine. Two of the air sample stations are maintained at CGS initiative and are not requirements of either the ODCM or EFSEC Resolution 332. I (e) Sampling is performed to meet NEI 07-07 guidelines and NPDES requirements.

(t) Soil samples are collected from five locations to satisfy EFSEC Resolution 332 requirements. Two samples are collected from locations near CGS, two from locations in Franklin County, and one collected from a control location. Sample locations listed in 3

Table 4-1 are the location sampled in 2013. EFSEC 332 requires strontium-90 analysis be performed if gamma analysis results (g) are greater than a specified threshold.

TLD Stations 71-86 are not included among the 34 TLD stations required by the ODCM. Alternate designations for these

£ stations are I S-I 6S. EFSEC Resolution 332 requires 25 or more TLD stations to be located within a 10-mile radius of CGS.

Other instruments, such as a pressurized ion chamber (PlC), may be used in place of or in addition to TLDs as per ODCM table 6.3.1-1 (b). CGS REMP maintains a uRem meter for this purpose.

(h) 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 location. The Station 27 sample, which is drawn from the plant discharge 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 332 requires samples from at least one downstream I

drinking water location and samples from the plant intake and discharge water systems.

(i) Composite samples are collected using automatic sampling equipment that collects samples based on a flow proportional or timed interval basis. If timed interval sampling is used, the interval period is short (e.g. hourly) relative to the compositing period 3

(e.g. monthly).

When the dose calculated via ODCM methodology for consumption of water exceeds I mrem per year, low level iodine-I 31 analyses are performed on the drinking water samples.

(k) Sampling from these locations fulfills ODCM table 6.3.1-1 3b requirements. EFSEC Resolution 332 requires sampling from at least one deep well used for fire protection and/or as a backup drinking water sources.

(I) Downstream sampling fulfills ODCM table 6.3.1-1 3d requirements. EFSEC Resolution 332 requires annual sediment samples upstream and downstream of the plant discharge.

(m) ODCM table 6.3.1-1 4a milk collection requirements cannot strictly be met due to the lack of milking animals near CGS. Milk samples are collected from the nearest dairy potentially impacted by CGS operation and also from a control location at the I

frequency specified in the ODCM. EFSEC Resolution 332 specifies sampling from at least one milk location within the 10-mile radius of CGS and also from a control location. Broadleaf vegetation can be sampled in lieu of milk if a representative milk sample is not available.

(n) ODCM table 6.3. 1-1 (k) requires that if cesium-134 or cesium-137 is measured in an individual milk sample in excess of 30 pCi/l iter, then a strontium-90 analysis will also be performed.

(o) 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 (i). There are no species fished commercially in the Hanford Reach of the Columbia I

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.

(p) 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 typically collected each sample period, when available. EFSEC Resolution 332 further specifies fruit and vegetable sampling from locations potentially impacted by CGS gaseous emissions.

(d) Though no gardens > 500 fi2 were identified, commercial agriculture is extensively practiced in some parts of the sectors identified in Table 4-3. Agricultural activities observed were primarily apple and soft fruit orchards, corn, alfalfa, and grape vineyards.

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 the Hanford External Dosimetry Program (HEDP) operated by Mission Support Alliance (MSA). All other CGS REMP samples were collected and 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 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 shows the 2013 "S"station mean quarterly TLD results separated into 16 geographical sectors around the plant. Figure 5-1 also shows the pre-operational mean and the high, low, and mean results in each sector for the 1984 - 2012 operational period for comparison. The 2013 "S" station TLD results were lower than the pre-operational mean in 11 of the 16 sectors and lower than the operational mean in 13 of the 16 sectors. TLD results from the N, NNE, and NNW sectors are slightly higher than the other "S" station locations as a result of being physically closer to the ISFSI and the CGS turbine building. Excluding the NNW sector, the average deviation relative to the pre-operational period was -1.40%; in 2012 the average deviation was -1.65%. The NNW sector is the closest "S" station to the ISFSI and the higher result here is attributed to the stations close proximity to this facility.

The 22 TLD locations designated as remote locations are located between 2.83 and 28.35 miles from the CGS reactor building; see Figure 4-3 for station locations. Figure 5-3 shows the exposure rates for the remote TLD locations separated into geographical sectors around the plant. Figure 5-3 also shows the pre-operational mean and the high, low, and mean results by sector for the 1984-2012 operational period for comparison. The 2013 remote TLD results were lower than the pre-operational mean in 9 of the 13 sectors and lower than the operational mean in 11 of 13 sectors. Station 46 in the Wahluke Reserve (NE sector) remained the remote location with the highest exposure rate. This has been the case since the pre-operational measurement phase and is attributed to differences in the underlying rock and soil composition in this area. The 2013 average deviation relative to the pre-operational period was -3.7%; the average deviation in 2012 was -3.5%.

Offsite direct radiation monitoring results are consistent with previous years. The 2013 results indicate no observable dose contributions 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 2013, the pre-operational period, and the long term operational period are summarized in Tables 5-3. See also Appendix A, Tables A-1.1 and B-1.1 for the 2013 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 radioiodines on a weekly basis. Air filters are also composited and analyzed for gamma emitting nuclides quarterly.

The 2013 mean weekly particulate filter gross beta results for the five stations 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 near plant stations are similar to results from the remote locations and closely follow the trend of the control location.

Figure 5-5 is a plot of the 2013 mean weekly particulate filter gross beta results for the 6 sample stations located between 3 and 9.6 miles from CGS (See also Appendix A, Tables A-2. 1, A-2.2). Results for these remote stations are similar to results from the near plant stations and closely follow the trend of the control location. No correlation between air gross beta activity and proximity to CGS was observed.

For both near and remote air station locations, higher results and greater variability in air gross beta activity have historically been observed during fall and winter months due to weather induced background fluctuations. Gross beta levels typically increase during periods of inversion due to natural decay products being frapped near the earth surface. Gross beta results plotted over a period of several years typically show a cyclical pattern with higher results observed in the fall and winter compared to the spring and summer. Gross beta results above the normal trend range were observed in January, October, November, and December. The increases were observed at all sample locations including the control and are attributed to weather phenomena and not the result of CGS operation. The results for weeks 48-50 were among the highest gross beta air results observed by the CGS REMP. Weather conditions for this period were typical. of an inversion with below normal temperatures, overcast skies, and little to no winds. The smaller spike observed in week 43 occurred during a period when fog and blowing dust was noted.

The 2013 air particulate and iodine sample results show no evidence of measurable environmental radiological air quality impact that can be attributed to CGS plant 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 2013 gross beta results for the plant intake, plant discharge, and river/drinking water stations are shown in Figure 5-6.

Figure 5-6 Gross Beta in River/Drinking ( Stations 26 & 29) and Plant Discharge Water (Station 27) for2013 All drinking and river water (Stations 26 and 29) gross beta results were below the analysis detection limits (See Appendix A, Tables A-5. 1, A-5.2). Gross beta levels in the plant discharge water (Station 27) were above the detection limits in ten of the twelve samples. Positive results for this location are expected due to the scrubbing action of the cooling towers which incorporates atmospheric particulate material into the discharge water and the concentration of natural radioactivity in the water by evaporative loss. Historically, higher gross beta results at Station 27 have been observed during periods when CGS circulating water was maintained at higher levels of concentration. The lower gross beta values for Station 27 during the summer months corresponds to a time period during and immediately after an outage. The Station 27 sample results are representative of the radioactivity present in plant discharge water before any mixing with river water occurs.

Monthly tritium results for all plant intake, plant discharge, and river/drinking water samples were below the analysis method a prioriLLD except for one plant discharge water sample. Tritium results for the three sample locations are plotted in Figure 5-7, quarterly averages for the locations are listed in Appendix A, Tables A-6. 1, A-6.2. The cause of the positive tritium activity in the March plant discharge water sample could not be identified; it is suspected that the activity was from recapture of CGS effluent tritium in the cooling water system.

Analysis results for the plant intake, plant discharge, and river/drinking water samples showed only negligible impact to the environment due to CGS plant operations in 2013. Composite water samples are I 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.

I 5.3.2 Ground Water Samples from 3 deep wells were collected quarterly to meet ODCM and EFSEC Resolution No. 332(9) requirements. Quarterly samples were also collected from ten shallow groundwater monitoring wells I

located near CGS as part of the CGS groundwater monitoring program. All well samples were analyzed for tritium and gamma emitting radionuclides. Well locations sampled are shown in Figures 4-1 and 4-2. U Analytical results for the three deep water wells were consistent with results seen in previous years.

Tritium results were below detection limits and no gamma emitting radionuclides related to CGS operation were identified in any of the samples (See Appendix A, Tables A-6.1, A-6.2, A-7.1, and A-I 7.2).

The CGS ground water monitoring program is conducted to meet the Nuclear Energy Institute (NEI)

I Groundwater Protection Initiative (NEI 07-07) (17)guidelines and to support NPDES requirements.

Ten shallow wells are routinely used to sample water 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 I

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.(19) The CGS groundwater program is intended to assess any contribution CGS may be making to I

the known groundwater contamination issue.

I 5-6 Energy Northwest/Columbia Generating Station I

2013 Annual Radiological Environmental Operating Report

Gamma Spectroscopy results for the ten shallow monitoring wells did not identify any gamma emitting radionuclides of interest(See Appendix A, Tables B- 10.1, and B- 10.2). Tritium concentrations at these locations ranged from < LLD to 15,400 pCi/liter (See Appendix A, Table B-11.1). Tritium results from each well were consistent during the year and within the trend range observed in previous years. The highest tritium concentrations were consistently measured at MW-5 which is hydraulically up-gradient of CGS. No samples were obtained from MW-7 in 2013 due to lack of water in the well. In 2011, ENW identified a possible correlation between tritium levels at the CGS storm drain pond and tritium levels at two nearby well locations (MW-7 and MW-8). Tritium results for 2013 showed a similar trend. Tritium activity in the storm drain pond is attributed to recapture of CGS effluents, see section 5.9.1 for more discussion. No other correlations between groundwater tritium and CGS operation weire identified. With the exception of the MW-8 tritium.

results, there is no evidence that CGS operation made a measurable radiological impact on groundwater.

5.4 Soil Gamma spectroscopy analysis was performed on soil samples from 5 different locations in 2013 (See Appendix A, Tables A-8. 1, A-8.2). Two of the samples were from locations near CGS, two were from locations east of CGS in Franklin County, and one was from a control location. Naturally occurring radionuclides (potassium- 40 and bismuth- 214) were identified in all samples. Cesium-137 was identified in one of the samples near CGS. The level of cesium-137 identified was within the range historically observed in local soil samples and within the range considered normal background in Hanford area soils.(20' 21,22) The cesium-137 level was well below the level that would require strontium-90 analysis to be performedi 91 The soil sample results indicate no measurable impact from CGS plant operation.

5.5 River Sediment Gamma spectroscopy results of river sediment identified naturally occurring radionuclides (potassium-40, bismuth- 214) and cesium-137 (See Appendix A, Tables A-9.1, 9.2). Relative to the circulating water discharge point, cesium-137 was detected in one of the upstream samples (Station 33) and both of the downstream samples (Station 34). The downstream cesium- 137 activity levels were similar to the levels identified in previous years and within the range known to be present in Hanford area sediment and soil.(21) Cesium-137 was not identified in any samples of plant cooling water discharged to the Columbia River. CGS has not made a radioactive discharge to the Columbia River since 1998. The sediment sample results indicate no measurable impact from CGS plant operation.

5.6 Fish The gamma spectroscopy results of fish samples identified low level cesium -137 in the anadromous fish collected from the Columbia River. The level identified was just above the analysis detection limit and substantially below the ODCM specified lower level of detection. Cesium -137 is occasionally identified in this media and has been identified at low levels in Columbia River fish by the CGS REMP and in other studies (23) in past years. The cesium -137 is not believed to represent an impact from CGS operation. Results of the other fish samples collected in 2013 identified only the presence of naturally occurring radionuclides (See Appendix A, Tables A-10.1, 10.2). Only two of the three ODCM required fish species were collected from both the control and indicator locations in 2013, see section 5.10 for further discussion.

I 5.7 Milk . - . I No radioiodine activity was identified in any of the milk samples collected in 2013 (See Appendix A, Tables A- 11.1, A- 11.2). Gamma spectroscopy results of milk radionuclides other than radioiodine did not identify the presence of any radionuclides of interest. (See Appendix A, Tables A- 12.19 A- 12.2).

Naturally occurring potassium-40 was identified in all milk samples.

5.8 Garden Produce Garnma analysis was performed on ten different types of fruits and vegetables in 2013 (See Appendix A, Tables A-15.1, A-15.2, A-16.1, A-16.2, A-17.1, A-17.2). No radionuclides of interest were identified in any of the samples. Naturally occurring potassium-40 was identified in all samples.

5.9 Special Interest Stations i 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, 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 I Installation (ISFSI) was first performed in 1998 to collect background data and TLD monitoring was established on the ISFSI fence line after construction was completed in 2002. Additional air monitoring and TLDs stations were established in 2008/2009 to monitor remediation work at the DOE 618-11 burial ground west of CGS. Discussions of the results from each of the locations are given in the following I

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. i 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 not positively identified in any of the monthly samples (See Appendix A, Tables B-3.1, B-3.2). Tritium was detected in eight of the twelve samples (See Appendix A, Tables B-4. 1, B-4.2). The samples with higher tritium levels were all from colder, wetter months which is consistentwith results seen in previous years. The source of the tritium in storm drain pond water is attributed to recapture of tritium from CGS gaseous effluents which is more likely to occur during cooler, rainier periods.

Four soil samples were collected from the CGS storm drain pond in 2013 and analyzed for gamma emitting radionuclides. The samples were collected from surface soil locations that were identified as having higher levels of activity in a 2011 storm drain pond soil characterization study. (24) Analysis of the 2013 samples identified many of the same radionuclides identified in the 2011 study but at levels generally lower than observed in 2011 (See Appendix A, Tables B- 12.1).

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- I 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.(16)

Gross beta results for Station' 102B (SWTF head works) were consistent with results seen in previous years. Gross beta results for Station 102A (DOE 400 Area effluent ) showed an increase over the course of the year rising from a level of less than 10 pCi/l in'the first half of the year to greater than 20 pCi/l in November and December. The increase is attributed to changes in the waste stream composition coming from the DOE 400 area and corresponds to decreasing discharge volumes from that facility. The sanitary sewer line from the DOE 400 area was plugged in mid-December 2013 and ENW is no longer accepting sanitary waste from this location. Gross alpha was not positively identified in any of the 102A or 102B 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 iodine- 131 in the January Station 102B composite sample. CR 278601 was written to document the finding. As no additional radioisotopes were identified in the sample, the source of the radioiodine was attributed to a medically administered treatment and not the result of CGS operation. No other gamma emitting radionuclides of interest were detected in any of the other SWTF samples analyzed in' 2013 (See Appendix A, Tables B-7.1, B-7.2).

Tritium activity was identified in all twelve 102A and five of the twelve 102B samples (See Appendix A, Tables B-8. 1, B-8.2). Tritium levels in the 102A samples were similar to the levels seen in previous years. The potable water used at the DOE 400 area is obtained from a groundwater well that is known to be contaminated with tritium as a result of past DOE activities on the Hanford site.(17)

Tritium concentrations in the 102B sampleswere no more than 2 times the LLD of the analysis.

Tritium activity in the station 102B samples is attributed to DOE 400 area discharges; 102B tritium values trending below the LLD during the second half of the year correspond to smaller discharge volumes from the DOE 400 area. Tritium levels in all sanitary waste samples remained well below the 20,000 pCi/liter action limits of EFSEC Resolution No. 300.16)

SWTF water from stabilization pond B was discharged to ground in March 2013. Grab samples were taken at CGS initiative during discharge and used to create a composite sample that was analyzed for gamma isotopic and tritium content. Gamma isotopic analyses of the composite sample did not identify any radioisotopes related to CGS operation. Tritium activity of the composite sample was determined to be 529 pCi/l. A total of 1.4 million gallons of SWTF water was discharged to ground in March 2013.

I 5.9.3 Cooling System Sediment Disposal Area (Station 119)

EFSEC Resolution No. 299(18) authorizes the onsite disposal of asdime nts from plant cooling systems I

containing low levels of radionuclides. The disposal area for these sediments is located just south of the CGS cooling towers. EFSEC Resolution No. 299( 8)requires direct radiation monitoring using quarterly TLDs in the vicinity of the disposal cells and the collection and analysis of a dry composite sediment I

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. I Cleaning of the CGS cooling towers was performed in May and October 2013. Disposal of the material removed resulted in an estimated 51.5 cubic meters of dry sediment being placed in the disposal cell.

Figure 5-8 summarizes theestimated mass and radionuclide content of cooling tower sediment that was I

placed in the disposal area in 2013. For those isotopes listed in the table that were not positively identified, the MDA value obtained from the sample analysis was used in the table calculations. As such, the total activity reported is a conservative estimate.

I In addition to cooling tower sediment, ENW performed cleaning operations of the Standby Service Water (SSW) ponds in 2013. Material removed from the SSW ponds was temporarily Stored in bags in a lined basin south of the SSW ponds. Initial characterization of the material identified cobalt -60 in the I

400-3000 pCi /kg range. Transfer of the SSW sediment to the established cooling system disposal area was initiated in December 2013 and completed in January 2014. Final determination of the volume, density and radionuclide content of this material will be reported in the 2014 annual report.

I Figure 5-8 shows that the cooling tower sediment results were well below the disposal concentration limits specified in EFSEC Resolution No. 299."1" Cesium -137 levels identified in 2013 were similar to I

levels identified in previous years and within the range normally seen in Hanford area soils. Positive identification of cobalt -60 has been made in this media in past years and at level similar to those shown in Figure 5-8. I I

Measurements of direct radiation at the disposal pit area was taken using TLDs. Two locations were used, an indicator location next to the collection area (Station 1199B) and a control location approximately 100 yards to the east (Station 119C). The mean quarterly 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 background due to material in the disposal cells.

(See Tables 5.3 and Appendix A, Tables B-1.1).

5.9.4 Spray Pond Drain Field (Station 120)

There were no discharges to the Spray Pond Drain Field (NPDES Outfall 003) in 2013. The TLD results at Station 120 in 2013 are in agreement with those seen in previous operational years (See Table 5-3 and Appendix A, Tables B- 1.1).

5.9.5 Independent Spent Fuel Storage Installation The Independent Spent Fuel Storage Installation (ISFSI) is a fenced, secured area north northwest of CGS. Ten TLD stations, stations 123-129 and stations 136A-138A, are located on the second of three security fences that surround 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 plant between the Transformer Yard and the ISFSI. Refer to Figure 4-4 for ISFSI TLD locations.

Radiological exposure rates inside the ISFSI security fence line are elevated and access to the area requires radiological dosimetry and security notification. In addition to the TLD monitoring program, quarterly radiological surveys of the ISFSI are conducted by the CGS Radiation Protection Department.

I No new spent fuel or additional storage casks. were added to::the ISFSI during 2013. As shown in I Figure 5-9, exposure rates at the ISFSI fence line have followed a downward trend since 2008.

Station 122 TLD results show a similar pattern with the long term trend for this location correlating to the overall ISFSI TLD trend but at a lower level. Station 12 1 TLD trend results show large I decreases during periods when CGS was shut down; this location has historically been influenced more by. turbine building radiation levels than by the ISFSI (See Table 5-3 and Appendix A, Tables B-

1. 1, 13-1.2). I 5.9.6 Additional Air Sample and TLD Locations Four air sample locations (Stations 87-90) and 5 TLD stations (Stations 58, 87-90) were established in I

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). No air samples were taken from these locations in 2013 as no work was performed at the 618-11 site that had the potential of impacting CGS.

I Quarterly TLDs were exchanged at all five locations in 2013. Three of the TLD stations (stations 87-89) had results higher than background due to the stations close proximity to the turbine building (See Appendix A, Table B- 1.1).

I 5.10 2013 Sample Deviations I A summary of REMP sample deviations encountered during 2013 is listed below in Table 5-1 a. All known deviations from the sampling schedule (i.e. sample was not obtained) or analyses where the ODCM specified lower limit of detection was not achieved are included.

6.0 QUALITY ASSURANCE AND QUALITY CONTROL 6.0 QUALITY ASSURANCE AND QUALITY CONTROL The REMP is designed to meet the quality assurance (QA) and quality control (QC) criteria of the NRC Regulatory Guide 4.15 7)and 10 CFR 50 Appendix B1 15). The contractors used for sample analysis, Energy Northwest Environmental Services, and Mission Support Alliance, 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 environmental TLD program covers the preparation, transportation, deployment, collection, storage, processing, and evaluation of the environmental TLDs and is designed to meet the requirements of NRC Regulatory Guides 4.13(8) and 4.15. (7 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 TLDs when transported to and from the vendor and also during deployment and collection 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 serve as checks that the dosimeter 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 2013 reader QC dosimeter results indicated satisfactory agreement for all periods. The quarterly 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. Evaluation of the 2013 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 sample media routinely analyzed.

2013 Annual Radiological Environmental Operating Report 6-1 Energy Northwest/Columbia Generating Station

I 6.2.1 Sample Collection Quality Control I Duplicate samples are collected and submitted for analysis when practical. The duplicate samples are used to assess the repeatability of the sample collection process and the precision of the analytical method.

I 6.2.2 Laboratory Instruments Quality Control 3 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 kept with the analytical results.

Analytical Instruments - Analytical instruments used for determining radioactive emissions in samples are calibrated for efficiency annually using standard reference material traceable to the I

National Institute of Standards and Technology (NIST). Below is a summary of the routine QC practices for the different analytical instruments.

• Gas-flow Proportional Counter: Background and performance checks are performed daily when in use. Control charts are maintained with two and three-sigma limits specified; the checks must fall within the two-sigma warning limits prior to use. Mid-batch QC and end of batch performance checks are typically performed.

• Gamma Spectrometers: Performance checked daily for efficiency, energy per channel relationship, 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 quarterly. A low level batch QC check is typically analyzed with each set of samples.

• Liquid Scintillation Counter: Background and performance checks are performed daily when in use. A performance check standard of the same matrix as the samples is analyzed and results trended. A control chart with acceptance limits specified is maintained. A low level batch QC check is typically analyzed with each set of samples.

6.2.3 Sample Batch Quality Control Sample batch analysis is normally performed with sample blanks and known-addition samples (or i 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.

Iodine-131 Cartridges - At least one known-addition sample is analyzed with each batch. A charcoal cartridge of the same type used for sample collection but spiked with barium-133 is used.

The 356 keV peak of barium-133 serves as a proxy for the 364 keV peak of iodine-131. Samples from the control location serve as blanks. i Gross Beta Filters - At least one unused blank air particulate filter and at least one known-addition air particulate filter is analyzed with each batch. 3 Aqueous Samples - In most cases, samples collected from the control locations are analyzed as blanks. A known-addition sample is typically analyzed with each batch of samples. i 2013 Annual Radiological Environmental Operating Report 6-2 Energy Northwest/Columbia 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 is typically analyzed with each batch. A replicate sample is 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 performinig 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 are investigated and corrective action taken.

The Energy Northwest Environmental Services Laboratory participated in three proficiency testing studies involving radioactive measurements provided by Environmental Resource Associates (ERA) during 2013. The Laboratory's intercomparison program was further supplemented by additional cross check media provided by ERA. The Laboratory's intercomparison program results for 2013 are shown in Table 6-2. All 2013 Laboratory intercomparison program results were within acceptable limits. Participation in the ERA studies serves to meet the intercomparison program requirements specified in the ODCM.

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.

6.4 Laboratory Quality Control Program Problems and Improvements No issues with REMP sampling and analyses were identified by the QC and intercomparison programs in 2013.

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 recommended 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 expected to fall within 95%.of the time, based on the statistics encountered in the original count.

Also included in most cases 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 aposteriori(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. .
