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. The program monitors direct radiation levels as well as airborne, waterborne, and ingestion pathways most likely to be affected by CGS operation. 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). Sampling and analysis is performed by the Energy Northwest Environmental Services group with analysis performed at the APEL facility located in Richland, Washington. Direct radiation services are provided by Battelle PNNL.

Direct radiation levels are monitored continuously with thermoluminescent dosimeters (TLDs) that are collected on a quarterly and annual basis. Offsite direct radiation monitoring results are consistent with previous years and indicate that there was no measurable dose contribution from plant operations. No measurable increase in exposure rates was seen inside the CGS controlled area relative to previous years. Radiation exposure levels at the Independent Spent Fuel Storage Installation (ISFSI) were similar to previous years with exposure rates trending gradually down. No new spent fuel was moved to the ISFSI during 2007.

The inhalation pathway was monitored by collecting and analyzing air particulate and air iodine samples weekly from twelve different locations. Results in most all case were consistent with background levels and within the range seen in the historical trend. No radionuclides related to CGS operation were identified in any of the samples.

The ingestion pathway was monitored by collecting samples of water, milk, soil, sediment, fish, and garden produce throughout the year. Results indicate no radiological impact that could be attributed to CGS operation in any of these sample media. Activity that was identified in these samples was predominately of natural origin. Small amounts of Cs- 137 were identified in some samples, however, the presence of this radionuclide in the environment is expected at low levels. Tritium was identified in some samples, but only in those where historically this isotope has been identified. The Cs-137 and tritium concentrations identified are consistent with levels known to exist in the surrounding environment. CGS did not make a radioactive discharge to the Columbia river in 2007 and has not done so since 1998.

No significant trends or changes in the environmental radiological levels in the vicinity of CGS were observed in 2007. The results seen in the 2007 samples are consistent with the results obtained in previous operational and preoperational years. No significant radiological impact to the environment due to CGS operation was identified.

3.0 INTRODUCTION

3.1 Site Description The Columbia Generating Station (CGS) 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.( 17) 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 periodically seen in some REMP samples; these radionuclides exist in measurable quantities throughout the world as a result of fallout from atmospheric nuclear weapons testing.(18)

Due to the location of CGS on the Hanford Site, there are other sources of reactor produced radionuclides in close proximity to the plant. Hanford related radionuclides, which are sometimes measured in CGS REMP samples, are distinguishable from those that may be present as a result of CGS activities by the absence of several characteristic shorter-lived radionuclides. The DOE has an active REMP program for the Hanford Site.

3.2 Program Background The CGS REMP is designed to conform to the Nuclear Regulatory Commission (NRC) Regulatory Guides 4.1 ,(Q)4.8,(2) and the Radiological Assessment Branch Technical Position.(3 ) In addition, the REMP also meets the requirements of IOCFR72.44(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. The variability in the background levels of radioactivity is due to differences in geologic composition, meteorological conditions, and seasonal changes.

2007 Annual Radiological Environmental Operating Report 3-1 Energy Northwest/Columbia Generating Station

a The Energy Northwest Environmental Services Laboratory performed the analysis of REMP I samples for 2007. The Pacific Northwest National Laboratory processed the thermoluminescent dosimeters used for the REMP in 2007.

1 In addition to evaluating the environmental concentrations against regulatory limits, the REMP also compares the results to state standards. ( 1 , 12,13) The results are also evaluated by comparing them to similar measurements made during the preoperational and previous operational periods and U to the detection capabilities associated with the current methods of analysis.

3.3 Program Objectives I The REMP provides a mechanism for determining whether the levels of radioactivity in the plant environs are within established limits and to ensure that the accumulation of radionuclides in the environment will not become significant as a result of station operations.

1 While in-plant monitoring programs are used to ensure that 10 CFR 20(') and 10 CFR 50(0) criteria for releases of radioactive effluents are met, the REMP provides verification of the effectiveness of 1

these programs and confirms that the concentrations of radionuclides in the environment are not greater than anticipated. I I

4.0 PROGRAM DESCRIPTION 4.0 PROGRAM DESCRIPTION The CGS ODCM defines the requirements for the REMP. The sampling plan presented in Table 4-1 shows which samples are required by the ODCM and the Site Certification Agreement (SCA). The table also provides a summary of the sample locations, collection frequency, and types of analyses performed. The methods of sampling and sampling frequencies utilized in the program have been determined by such factors as the half-lives and major exposure pathways for the radionuclides potentially released from the plant to the surrounding environment.

4.1 Sample Locations Ninety-five sampling locations (referred to as 'stations') are included in the monitoring program.

Eighty-five indicator and three control stations are located within a 10-mile radius of CGS. Three additional control stations and four indicator stations are located outside of a 10-mile radius from the plant. Sample stations are listed in Table 4-2.

The locations of most of the stations used for sampling 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. Additional samples are collected at locations as specified by EFSEC Resolution 260(6). Samples for the REMP collected from stations in areas that are likely to be influenced by CGS are used as indicators. Other samples collected from stations in areas that are not likely to be influenced by CGS serve as controls.

The results from the indicator stations are compared to the results at the control stations, and also to the results obtained during the previous operational and preoperational years of the program.

The REMP sampling locations listed in Tables 4-1 and 4-2 are shown in Figures 4-1 through 4-5.

Figure 4-3 shows the relative locations of the storm drain outfall and pond (Station 101) and the Sanitary Waste Treatment Facility (Station 102). Also shown are the cooling tower sediment disposal area (Station 1 19B and Station 119-Control) and the spray pond drainfield (Station 120), which are special interest stations.

4.2 Independent Spent Fuel Storage Installation (ISFSI)

The Independent Spent Fuel Storage Installation (ISFSI) was constructed to provide additional storage capacity for spent fuel. The spent fuel is stored in HI-STORM dry storage casks, which are placed on one of two concrete pads, each measuring 30-feet wide by 135-feet long. The ISFSI is located approximately 500 meters north-northwest of the reactor building.

REMP monitoring of the ISFSI is performed with a set of quarterly and annual TLDs located at 10 stations on the isolation fence surrounding the pads. In addition, two other stations are located on other fence lines. Station 121 is located on a fence line approximately 200 meters north of the turbine building and Station 122 is located on the fence approximately 100 meters north of the ISFSI.

Figure 4-4 shows the ISFSI location in relation to CGS. Figure 4-5 shows the location of the 10 TLD stations located around the ISFSI. This arrangement of TLDs in conjunction with the other monitoring activities that are conducted in support of CGS REMP, satisfies the monitoring requirements listed in 10 CFR 72.44(d)(2) for the ISFSI.

2007 Annual Radiological Environmental Operating Report 4-1 Energy Northwest/Columbia Generating Station

I 4.3 Land Use Census 3 A land use census for areas within five miles of CGS is performr.ed annually. The objectives of the land use census are to identify the locations of the nearest milk animal, residence, and garden greater than 50 m2 (approximately 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 were found, routine sampling of that dose pathway would be initiated at that new site.

The results of the 2007 land use census within five miles of CGS are presented in Table 4-3. No significant changes from the 2006 land use census were observed.

4.4 Sampling Methods 3 Energy Northwest personnel collect environmental ,samples in accordance with the program plan in Table 4-1. Procedures for sample collection and TLD handling are contained in the department instructionrmanual. 'Samples that were collected for the REMP in 2007 wereItransported to the EnergyI Northwest Environmental Services Laboratory shortly after collection. Generic descriptions of the sample analysis methods that are'employed for the analysis of CGS REMP samples are described in section 4.5. This section describes the sampling methods and sample locations. I 4.4.1 Direct Radiation Direct radiation dose levels are monitored with Harsha'w Model 8807 thermoluminescent dosimeters I (TLDs). Two sets of TLDs are placed in the field approximately three feet above thie 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 4:5.

Station 9A in Sunnyside, serves as a control for CGS TLDs. Station 119-Control serves as the control 1 for Station 119B (the cooling tower/system sediment dis*osal basin). The remaining TLDs deployed in the field serve as indicator TLDs. ' . " 3 The TLIDs are arranged in a series of rings that encircle CGS. The innermost ring of TLD stations,'

which are located inside the fence line at 'distances that range from 0.3-0.8 miles fromthe reactor building centerline, arereferred to as the 'S stations.' The next ring of TLDs, referred to as the '-near plant" stations, are located at distances ranging from 1-2 miles from the reactor building. The outer ring of TLDs are located at distances that range from a little under three (3) miles out to around ten (10) miles' A Thermo MicroRem doserate meter is available as a backup device and to take real time' readings as needed. *' '*

4.4.2 :Airborne!- Particulate/Iodine '.

Air particulate and air radioiodine (1-131) samples are obtained through the use of low volume (1.5 cfm), constant flow-rate sampling units at 12 locations. The samples drawn at Station 9A (Figure 4-2) are considered controls, the samples drawn at the other locations (Figure 4-1) are indicators. Air particulate samples are collected by drawing air through a 47-mm diameter glass fiber filter. Air iodine samples are collected by drawing air through 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 2007 Annual Radiological Environmental Operating Report 4-2 Energy Northwest/Columbia Generating Station

ventilated metal weatherproof housings mounted on elevated platforms at each air sample location.

The filter media are changed weekly.

4.4.3: Water' There are nine locations where water sampling is performed for the REMP. They are categorized as follows:

0 Intake-River/Drinking Water; two locations (Stations 26, and 29)

• 'Groundwater; three'locations (Stations 52, 31, and 32)

• 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-drawn from the plant intake water which comes from 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 located at the Richland Water Treatment Pl ant,* 1 milesdownstream from the discharge and is the indicator station for both river and drinking water.

The ODCM requirement for a downstream water sample "near but beyond the mixing zone" is conseryatively met by.sampling-water from Station 27, the cooling tower discharge line to the Columbia River. This, sample reflects the radioactivity.present in the plant discharge prior to any river dilution, rather than the, concentrations that.0wo Ild be found after dilution in the mixing zone.

The Station 27 sample is an indicator. Composite samplers are, used, to collect samples at.Stations 26, 27, and 29. The samplers collect 25-ml aliquots of water at regular intervals. Samples are collected monthly at eachoof these stations andare analyzedfor gamma,, gross beta, and tritium.

Threewells within the. vicinity of C.GS.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-downgradient from CGS&. Water from the CGS well 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 of these wells and are analyzed for gamma emitting radionuclides and tritium.

Water samples are collected monthly from the storm draip outfall (Station 101) using a flow-proportional composite sampler. These samples are analyzed for gross beta, gamma, and tritium.

The 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 No. 300(")*. A flow meter and composite sampler is located on the 400 Areasewer line justabove the 400 Area/Plant Support Facility (PSF) intertie (Station 102A). The sampler collects aliquots of the effluent on a timed basis, the composite sarnple that is produced is analyzed monthly as required by EFSEC Resolution No. 300.(15)

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 2007 Annual Radiological Environmental Operating Report 4-3 Energy Northwest/Columbia Generating Station

I Station 102A has tritium concentrations normally above 2000 pCi/liter. Another automatic water sampler is located at the headworks of the SWTF (Station 102B) where a monthly composite sample is 3

taken.'Both sample locations are analyzed for gross, .alpha,,gross beta, tritium, and gammaemitting radionuclides.I 4.4.4,. Soil Annual soil samples are collected at the indicator Stations 1, 7, 21, and'23 as required by EFSEC Resolution 260,( A sample is also collected at the control location, Station 9A (Figure 4-2). 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, If the Cs-I137 level in an indicator sample exceeds ten (10) times the level in the conftrol sample, strontium analysis is required(6).

4.4.5 Sediment 3 River sediment samples are collected semiannually as required by the ODCM. 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. 1 Coolirig tower sediment samples are collected and analyzed whenever additional cooling tower sediment is added to the disposal cells (Statqionn1 19B, Figure 43).' Disprsal in the Station l19B dcells is made in accordance with EFSEC Resolution No.: 299(16) ' I Wastewater sludge/sediment samples are collected annually at Station 102D (the SWTF). All sediment samples are analyzed for gamma activity. i

4.4.6 Fish Annual fish sampling is usually performed in late summer or fall. Fish samples collected from the Columbia River (Station 30 in Figure 4-1) are indicator;samples, whereas fish collected on the'Snike River (Stations 38 and 38A in Figure 4-2) serve as control samples. 3 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 fish collection, except for the samples of the anadromous species, which are collected at the fish hatcheries.

4.4.7 Milk Milk samples are collected m6nthly during the fall and w~inter months' (October through 'December).

During the spring and summer months when cows are likely to be grazing or on fresh feed, milk samples are collected twice each month. Enough raw milk is collected from each sampling location to obtain a one-gallon sample after the cream has been skimmed off. The milk samples are normally processed and analyzed within four days of the collection date.

Milk samples were Icollected in 2007 from two locations, Station 36, and Station 9B. Station 36 is in Franklin County and is'theonly dairy within a ten mile iadius~of CGS. Station 9B is in the Sunnyside/Grandview area (Figure 4-2). The Station 9B dairy location changed in 2006,'wiih the Meeker dairy replaced by the Scheenstra dairy. The new location is only a short distance from the old location and serves as a better control as the dairy cows feed exclusively on material grown in the control location.

4.4.8 Garden Produce Samples of local garden produce are collected monthly during theigrowing season when the produce is readily available. When possible, three types of produce samples (a root crop, fruit, and a leafy vegetable) are collected at each location. Tihe indicatoiI samples are collected from a region in the predominantly downwind direction (Station"37) where crops are irrigated with Columbia Rixvr water.

The control samples are obtained from produce stands in the Sunnyside area (Station 9C in Figure 4-2),

the direction least likely to be affected by plant effluents. Apples are collected in late summeror early

.fall from Station 91, the Rio VistaFarms orchard, which is irrigated with Columbia River water. A small garden is maintained by ENW REMP personnel next.to the SWTF and has been designated as Station 102G. The garden supplied broadleaf samples for analysis in 2007.

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). The REMP field samples were analyzed~by Energy NorthwestEnvironmental Services.,

Sample holding times prior to analysis are kept as short as possible in order to ensure that the .LLD requirements for shorter lived radionuclides are met with reasonable counting times. In samples where very long lived isotopes are the only isotopes of concern, longer sample holding times are permitted.

Sample countftimes were conservativelycalculated to insure required a prioriLLDs were achieyed.

4.5.1 Analysis of TLDs.

The REMP TLDs are measured at the Pacific Northwest National Laboratory (PNNL) 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 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 and the trip control results.

£ 4.5.2 Gross Beta Activity on Air Particulate Filters 3 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. I 4.5.3 Measurement of Gamma Emitting Radionuclides Shielded, high purity germanium (HPGe) detectors are used to assay environmental samples to I quantitatively determineconcentrations of 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. - g

• Solids Soil, sludge, and sediment'samples are drned and if needed ground. Foodstuff, biota (fish), and vegetation, are chopped finely or puieed'and then analyzed wet (no drying is done). For foodstuff (including fish), only the edible portion of the sample is used.

Measured aliquots Of the solid samples (0.5 or 1.0"liter depending on, Sample type and sample U

quantity) are placed into tared containers and weighed. Results are reported in pCi/kg.

• Charcoal Cartridges - As manY as five charcoal cartridges may be counted simultaneously with one positioned on the face of the detector and up'to four on the sides of the detector in a cartridge holder. Detector calibration files are maintafined for both face mount and side mount positions. Sample volume for each group, cartrdge count is conservatively set to the lowest cCartridge sample volume in the group. If 1-131 is identified in the assay of a group, each charcoal cartridge in the groupis :assayed sep aaely. Resultar 3.

are decay corrected to the mid point of the sample collection period. 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 3

is determined by weighing the planchet before and after mounting the sample. The planchet is counted for alpha and/or beta activity using an ,autpmatic gas flow proportional counter. Results I are corrected for sample self-absorption using the sample residue mass values. Results are reported in pCi/liter. . , I 4.5.5 Tritium in Water The sample is distilled then 8.OmL of distillate is mixed with 12.OmL of scintillation cocktail. The mixture is counted in an automatic liquid scintillation analyzer. Results are reported in pCi/liter.

4.5.7 Low Level Iodine-131 in Milk and Water Four liters of saimple arehfirst eqUilib'at'edwith stable iodide' carriest. A batch treatment with an anion exchange resin is used to remove iodine from the' sample. The resin is then removed' froimi.the liquid sample and loaded into a small container and counted directly by gamma spectroscopy. Results are reported in pCi/liter.

4.6 Data Analysis Methods Since mid-1984, the results of the REMP analyses have been presented as net results calculated frdm gross or total counts minus the observed background counts of the detection method. Counting results for low level samples ar ofien Within the counting error of the' backgr6und determination, con-sequently results can range from negative to positive values in these samples: Though most of the REMP analytical results 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'"(<) ,alues. This is a normal practice in radiological environmental reporting. A listing of the Energy Northwest nominal target LLDs (a priori)for each sample type is prdvided in Table 4-4; the ODCM required LLDs are also included for a comparison. The actual,.observed LLDs (a posteriori)may vary due to' sample hold time's and available sample volumes.

Plots of the sample results. versus time*are used'to represent the results for analyses such as gross beta on air particulate filterS,"whfiere the resilts are n6rmally above the detection limit. ..in Such cases, the indicator station results 'are plotted 'with the cofntrol' stationi 6sults for easy comparison. Other data analysis techniques are also used to"evaluate whether' trends' that could be attributed to CGS operations arebevident. REMPproam1ata t*endfing has been identified as an area for improvement.

Thermoluminescent dosimeter (TLD) data' is-presented'int'erms f the net mR/day exposure rate.

These results are determined from the total exposure (in mR).calculated for each TLD minus the TLD Sbackground dan any trAnsit (or trii) exp~slire reeived dutring di'stribution and retrieval, and divided by the number of days the TLD. was in the'field. 'Th6btotal*'mR/s'tandard quarter and mR/year values are alsoieidrted (See Tables 5-3, 5-4).

The quarterly TLD results are compared with the annual TLD results and expressed as a ratio by dividing the sum of the quarterly results over the annual results (see Table 5-5). The agreement between the two sets is usually withinpl~us or minus ten percent (10%); occasionally fade can be more significant than expected in the annual'set and the results maybe lower than the sum of the quarterly data.

4.7 Changes to the Sampling Program in 2007 There were no changes made to the sampling program in 2007. Sampling of shallow wells atound CGS was performed in 2007 as an Energy Northwest initiative and may continue in the future.

FOOTNOTES (cont):

(d) EFSEC Resolution 260 requires nine or mrre air samplingsta'tions.

(e) If gross beta activity is greater than 10 times the mean of the result for the control, Station 9A, gamma isotopic analysis shall be performed on the individual sample.

(f) Gamma isotopic means identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents of CGS.

(g) Soil sarmples are collected to satisfy the requirements of the SCA for CGS. EFSEC Resolution 260 requires that soil samples be collected at five air-sampling locations.

(h) Sr-90 analysis shall be performed on any indicator soil sample having cesium results greater than ten times the result for the control location.

(i) TLD an abbreviation for thermoluminescent dosimeter.

(j) TLD Stations 71-86 are not included among the 34 routine TLD stations required by the ODCM Table 6.3.1-1. Their alternate designations are IS-16S. EFSEC Resolution 260 requires 25 or more TLD stations to be located within a 10-mile radius of the plant.

(k) Pressurized ion chambers (PICs) or similar are required by ODCM Table 6.3.1 - llb to be maintained as a supplemental or backup system.

(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 line, is taken in place of a d'ownstream" water sample near but beyond the mixing zone. It reflects the radioactivity present in the plant discharge prior to any river dilution. EFSEC Resolution 26 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.

(m) Composite samples are collected with equipment that collects an aliquot at time intervals that are short relative to the compositing period.

(n) When the gross beta activity in drinking water exceeds 8 pCi'iter, a Sr-90 analysis is performed.

(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.

(p) tFSEC 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 animaIs that are located in the most prevalent wind directions from CGS. EFSEC Resolution 260 requires at least three milk locations within the I0-mile radius of the plant and one in a control location, however, Energy Northw,'est currently has access to only one dairy within a I0-rfiik radius of the plant (Station 36) and one control location at 30 miiles. Broadleaf vegetation can be sampled in lieu of milk if a representative milk sample is not available.

(s) Footnote removed.

(t) If Cs-134 or Cs-137 is measured in an individual milk sample in excess of 30 pCi/liter, then the Sr-90 analysis will be performed.

(u) There are no species fished commercially in the HanfordReach 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.

(v) If an impact is indicated, sampling will be conducted semiannually.... .......-

(w) 'Garden produce will routinely be obtained from farms or gbdensusing Columbia River water for irrigation when available. One sample of a root crop, leafy vegetable, and a fruit is collected each sample period, if available. The variety of the produce obtained will be dependent on seasonal availability.

(x) Station 91 is an apple orchard irrigated with Columbia River water. The apple crop from Station 91 is sampled annually.

(y) Station 102G was used to collectione sample. This station does hot meet the ODCM criteria for a garden which requires sampling; it was used to provide a broadleaf sample that was grown inside the 5-mnile radius from the plant.

5.0 RESULTS AND DISCUSSION 5.0 RESULTS AND DISCUSSION REMP samples were analyzed by the Energy Northwest Environmental Services Laboratory in 2007. The environmental TLDs were analyzed by Battelle at the Pacific Northwest National Laboratory (PNNL). Table 5-2 provides a summary of the REMP results for 2007; the 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 or EFSEC required detection limits and are not the method detection limits listed in Table 4-4. The data tables for the 2007 report are presented in Appendix A of this volume and summarize the analytical results in greater detail.

The analytical results for the REMP sampling locations during 2007 are very similar to the results reported for previous years. No significant trends indicating an environmental impact, unexpected changes in the environmental concentrations, or exposure levels at REMP monitoring stations were observed.

5.1 Direct Radiation The environmental radiation exposure rates measured near the plant and at remote stations were consistent with exposure rates seen in previous years. Figure 5-1 presents a plot of the 2007 mean quarterly TLD results for each of the sixteen meteorological sectors nearest the plant. These "S" station locations are located 0.3-0.8 miles from the reactor and are all inside the property boundary.

Figure 5-1 also shows the high, low, and mean result in each sector for 1984 through 2006. The TLDs in the N, NNE, and NNW sectors show higher exposures rates than other "S" stations as a result of being physically closer to the plant turbine building and the ISFSI. Results for the NNW sector were again above the long term average; this has been the case ever since spent fuel was moved to the ISFSI. TLDs in all other sectors show results below the preoperational and long term operational mean. A similar pattern has been observed since 2004.

Environmental radiation exposure rates for 2007, the preoperational phase, and'the long term operational phase are'summarized in Tables 5-3 and 5-4. Table 5-5 list a comparison of the 2007 annual and'summed quarterly TLD results.

5.2 Airborne Particulate/Iodine The 2007 mean weekly particulate filter gross beta results for the inner ring indicator stations (those within three miles of CGS) are plotted in Figure 5-4. With the exception of the week 3 results, results are within the ranges observed during the previous operational periods. Figure 5-5 is a plot of 2007 mean weekly particulate filter gross beta results for the remote stations (those beyond 3 miles of CGS). A similar trend to that seen with the near plant results is observed The control location (Station 9A) trend follow a nearly identical pattern to the remote and near-plant locations.

I A two times increase above the historic grossbeta mean was seen in weeks 3, 4, 5, 22, and 47 for I both the near plant and remote stations. The increases were seen across the board, being observed at all indicator locations as well as the control location. Only the week 3 mean was noticeably above the control value. This discrepancy is believed to be due to climatic difference between the indicator and control locations that occurred that week. 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 of several years show a cyclical pattern of fall and winter increases. The week 22 (ending 6/5/07) increase is associated with unstable weather conditions with very hot conditions mid week followed by thunderstorms. There is no indication that any of the increases were due to CGS activities or effluents.

The quarterly particulate filter gamma isotopic results indicated only the presence of naturally occurring radionuclides (See Appendix A, Tables A-3.1, A-3.2). Be-7 was positively identified in all samples at both the indicator and control locations.

The 2007*weekly iodine partridge isotopic results showed no indication of 1-131 in any of the samples with resultxin all rases1being below- the 1-131 lower level of detection ( See Appendix A, Tables A-3.1, A-3.2).

Based on these results, there is no evidence of any measurable impact from plant operations on the environment in the air particulate filter and chaicoal cartridge results for 2007. U 5.3 Water Gross beta results for the plant intake and river/drinking water were within the normally observed ranges (See Appendix A, Tables A-5.1, A-5.2). All drinking and river water (Stations 26 and 29) gross beta results were less than 8 pCi/liter. State drinking water standard for Sr-90 (") require a strontium analysis be performed when gross beta results are above the 8 pCi/liter level. The gross I

beta levels in the plant discharge water (Station 27) were on average 9.3 times higher than the levels seen in the intake water (Station 26). Higher activity is expected in the discharge water as natural radioactivity is concentrated due to evaporative loss and the scrubbing action of the cooling towers I

which incorporates atmospheric particulhte material into the water. The Circulating Water cycles of concentration for the 2007 operation period was9- 10 which is in good agreement with the discharge/intake gross beta ratio. The discharge sample results are representative of the I

radioactivitypresent in plant discharges before any mixing with river water occurs. Gross beta results areplotted in figure 5-6.

Tritium levels in all river/drinking, plant discharge, and deep groundwater well samples were below the detection limit (See Appendix A, Tables A-6.1, A-6.2). This is consistent with the results seen in previous years. Tritium results are plotted in Figure 5.7 I

Gamma spectroscopy results of river/drinking, plant discharge water, and deep groundwater well samples showed no indication of radionuclides of interest being present in any of samples. Some 3

naturally occurring radionuclides were identified as was expected. (See Appendix A, Tables A-7.1, A-7.2). I 2007 Annual Radiological Environmental Operating Report 5-4 Energy Northwest/Columbia Generating Station U

A number of shallow groundwater samples were collected in 2007, see Section 5.9.6 for results and discussion. There is no evidence of any measurable impact on the environment due to CGS plant operations in the river/drinking, plant discharge, or deep groundwater sample results for 2007.

I 5.4 Soil U Gamma spectroscopy analysis was performed on soil samples from 5 different locations in 2007 (See App;endix A, Tables A-8. 1, A-8.2). Results indicated the presence of'naturally occurring radionuclides (Be-7, K-40, Bi-214, and Ra-226) and Cs-137 in almost all samples. Cs-I137 concentrations' in all indicator locations were less than that observed the previous year; however, the control Cs- 137 concentration was slightly higher. The Cs-I137 concentrations identified are within the range considered normal backgroundlevels and consistent with Cs-I 37 concentrations found inHanford site soils.1 9'21 ) No indicator location had Cs-137 concentrafions high enough above the control location to trigger a Sr-90 analysis as required by the ODCM. (8)The soil sample results did not indicate a measurable impact from CGS plant operation.

5.5 River Sediment,.

Gamma assays of river sediment identified several naturally occurring radionuclides (Be-7, K-40, Ra-226, and Bi-214) and Cs-137 (See Appendix A, Tables A-9.1, 9.2)' Cs-137 was detected in both the upstream (Station 33) and downstream (Station 34) samples (relative to the cooling tower dischargepoint). Both the upstream and downstream results are consistent with results seen in previous years: Cs- 137 activity in the ranges identified has beenprevidusly identified as a component of the Columbia River sediment originatingfrom Hanford'site activities , weapons I

testing fallout, and natural background. 3 5.6 Fish The gamma spectroscopy results of fish samples collected in the Columbia River identified the I presence of Cs- 137 in two of the samples. Both sample results were',< 10 pCi/kg Cs-I 37: and just'r above the detection limit (See Appendix A, Tables A-10.1, 10.2). These levels are substantially, below the ODCM required detection and repori-tig -imitui.-CI 137 has not b6en' ideritified iniREMP fish samples for at least the last five years, however,Ahis -isoto9.pe has been identified iniColumbia' river fish by other studies.(z2 ) No'radionuclides were psitively identified in fish samples collected from the control location on the Snake River.:

5.7. Milk There was no detectable 1-131 activity identified in anyof'the milk-samples collected in 2007 (See Appendix, A,. Tables A- 11.1, A- 1.2). Gamma sliectroscopy results of milk radionuclides other than 1-131 did not identify the presence of any radionuclides of interest above detection limits (See Appendix A, Tables A- 12. 1; A- 12.2). Naturally occurring, K-40 was .identified in all milk samples.

5.8 Garden Produce Gamma analysisiwas performed on nine different fruit and vegetable crops in 2007 (See Appendix A, Tables A715.1, A- 15.2, A716.1, A- 16.2, A- 17. 1, A- 17.2). Results were below the detection.

limits for all radionuclides of interest with the exception of two positive Cs- 137 results obtained on vegetables obtained from a small garden grown on Energy Northwest property (Station. 102G). A vegetable: sample from this site had a positive Cs- 137 result in 2006 also. Investigation found the vegetables were grown in artub using a commercial soil mix purchased from a local garden supply center. Analysis of the tub soilshowed Cs-,137 levels of 203, pCi/kg where a, ground soil sample taken from the 102G site showed only,28.pCi/kg Cs-. 37. This indicates that.the source of~the.Cs-137 is most probably from the commercial soil mix and not CGS operation. The site 102G garden tubs are to be filled with a new soil mix in 2008 that will be analyzed prior touse, Naturally occurring K-40 was identified in all samples as expected.

5.9 Special Interest Stations 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 thespray pond drainfield (Station 120) in June 1995. TLDs were hung in the vicinity of the planned Independent Spent Fuel Storage Installation (ISFSI) duringthe first quarter of 1998 to collect background data and an additional ten TLDs were hung on the ISFSI fence after construction was completed in 2002. Discussions of the results from each of the locations are given in the following sections.

5.9.1 Storm Drain Pond (Station, 101)

The. storm drain pond is located appr ximatly 1500 feet northeast of CGS. Water is sent to.the pord*it ough an I 8-inch diameterpipe.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 uising a flow proportional automatic sampler tocollect monthly composite samples.

Monthly Samples were analyzed for tritium, gross beta, and gamma emitting radionuclides. Only natural occurring radionuclides were identified ,in the gamma. spectroscopy results (See Appendix A Tables. B-2. 1, B-2.2). The August composite. K-40 result was: unusual as it was exceptipnally, high (1680 pCi/liter). Two of the samples: had gross beta results above the detection,limit; the February result was j ustabove the detection limit and the August result almost 10 Itimes -higher.,:

than the detection limit (See Appendix A, Tables B-3.1, B-3.2). The high level of K-40 identified in the August sample would account for a higher gross beta result. Tritium was detected in one half of the ST 101 water samples with higher activity identified during the colder, wetter months (See Appendix A, Tables B-4. 1, B-4.2). The source of the tritium in these samples is believed to be capture and condensation of tritium from CGS effluents during cooler, rainy periods. Tritium concentrations were consistent with levels seen in previous years.

2007 Annual Radiological Environmental.Operating Report 5-7. Energy Northwest/Columbia Generating Station

I 5.9.2 Sanitary Waste Treatment Facility (Station 102) i The Sanitary Waste Treatment Facility (SWTF) is located .approximately 0.5 mileS south-southeast of the CGS. The facility processes the sanitary waste water from CGS, the.ENWIndustrial Development Complex (formerly referred to as WNP- I and. WNP-4), the Kootenai Building, and the DOE 400 Area (since April ,1997). Discharge standards and monitoring requirements for the SWTF are established in EFSEC Resolution No. 300(15).

The monthly composite gross-alpha and beta results for the 400 Areaeffluent (Station 102A) and the SWTF headworks (Station 102B) were lower than levels seen the previous year (See Appendix A, Tables B-5. i, B-5.2, B-6.1, B-6.2). The lower values mostly reflect a change in the I

background method used to calculate results. Low level gross beta was identified in all samplesi and gross alpha was not, this is the normal observation for these samples,.-

Gamma spectroscopy results of the monthly SWTF samples showed no radionuclides of interest were detected in any of the samples, though some naturally occurring radionuclides were identified (See Appendix A, Tables B-7.1, B-7.2).' This is consistent with results from previous U

years. The annual sediment sample -collected from the north stabilization pond (Station 102D) contained Cs- 137 and Co-60 at concentrations that W~ere'similar to results seen in p.revious years (See Appendix A, Table B-9.1).

Tritium activity was identified in all SWTF Station, 102A and 102B samples with the levels.

identified consistent with levels seen in:previous years (See Appendix A, Tables B-8.1 B-8.2).

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 l Hanford site. Tritium activity coming from the DOE 400 area i§ the main 'source of theltritium identified in the station 102B sarmples,' as this. location'contains water from all locations noted above, including the DOE 400 area,' ' ... . r 5.9.3 Cooling Tower Sediment Disposal Area (Station 119)

EFSEC Resolution No. 299('6) authorized the onsite disposal of sediments from plant cooling systems containing very low levels of radionuclides: The disposal area for these sediments is 3

located just south of the cooling:towers., Resolution No. 299 requires the REMP to monitor the' direct radiation dose using quarterly and annual TLDs in the vicinity of the disposal cells.

Resolution 299 also requires the collection 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 done twice in 2007. An estimated 49.7 cubic meters of dry sediment was placed in the disposal area in June and an additional 3.5 cubic meters was added in' Noverniber. Using analysis MDA values for those isotopes that were not positively identified, the following table summarizes the estimated quantity of radionuclide that were placed in the disposal area in 2007. Theresults are belowthe disposal concentration limits specified in EFSEC resolution 299.

detection limits. The Cs-137 activity levels are in. a range similar to that seen in Columbia River sediment samples. The source: ofQthe Co-60, activity is, most likely from capture and concentration from plant air emissions or from concentration of activity in Columbia River water. As the results for the other radionuclides are less than the detection limit, the reported quantities in the table for these radionuclides; are conservative.estimates; 'A more accurate method for determining the sample density, was used in 2007 resulting in' lower estimated activity per volume than that reported in,:

previous, years. r Measur.ements of direct radiation at the disposal basin. were taken using TLDs. Two locations, were used, an indicator location next topthe, collection area :(Station I1!9B.) and a control location approximately 100 yards to the east (Station 119-Control). The mean quarterly and annual TLD.

results agree well with results from previous operational years. The negligible difference between the indicator and the control TLD indicate that there was no significant measureable dose above background. (See Tables 5.3, 5.4 and Appendix A, Tables B-1.1, B-1.2) 5.9.4 Spray Pond Drain Field (Station 120)

There were no discharges to the Spray PondDrain Field in, 2007., The TLD results at Station 120 in 2007 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).,

5.9.5 Independent Spent Fuel Storage Installation The Independent Spent Fuel Storage Installation (ISFSI) is in an area immediately north of the CGS.. TLD station 121 is located approximately 0.1 mile north, of the plant and is between the plant and the.ISFSI. TLD station 122 .is on the fence line approximately 0.3 mile north of.the plant.. Ten. more T.LD. stations are located on the security fence surrounding the ISFSI., These stations areStations 123-129 and Stations, 136A-138A. Though the dose rate at the ISFS.

security fence is elevated, access to the area directly outside the fence is restricted and requires radiological dosimetry and security notification to enter.

2007 Annual Radiological Environmental Operating Report 5-9 Energy Northwest/Columbia Generating Station

I No new spent fuel storage casks were added to the ISFSI in 2007. The last spent fuel transfer was made in 2004 and most ISFSI security fence TLDs show a decreasing trend since that time (See Table 5-3, 5-4-and Appendix A, Tables B-1. 1, B1-12). The station 121 TED result for the second quarter showed a sharpdrop followed by a sharp rise in the third quateri. Station] 21 "is located between the ISFSI and the turbine building, a similar trend has been observed in pr'evious outage years. This behavior appears to be due to changing turbine building radiation levels; during the second quarter CGS was shut'down for,the R-18 outage and during the third quarter it was operating at 100% power.

5.9.6 Miscellaneous Environmental Sample Results I As part ofCGS response to the NEI groundwater initiative, water samples from six shallow wells around-CGS were.collected and analyzed for gamma emitters and tritium in 2007. No gamma emitting radionuclides of interest were identified in any of the samples (See Appendix A, Table B-10.1). Tritium results ranged-from <LLD to 16800 pCi/liter (See-Appendix A, Table B-10.2).

The shallow aquifer directly below CGS is known to be contaminated with tritium asa result of past DOE activities on the Hanford site.(20 ) None-of these wells are used as a drinking water source.

There were no significant (> 100-gallons)on site leaks or spills of contaminated water in 2007.

On 4/13/07, an estimated one million gallons of non-contaminated 'secondary plant cooling water escaped out of the cooling tower overflow weirs and flooded an area to the south and southeast of the cooling towers. The incident is documented in CR 2-07*03391 'Because of the I potential to leach contamination from-onsite radioactive matefial storage locations, water and soil samples were taken the day after the incident and analyzed for radionuclide content. No radionuclides of interest were identified in the samples.

5.10 2007 Sample Deviations' Three sample deviations were encountered in 2007, all:were the result of electrical problems'.

connected with air sampling. For comparison, there were two deviations reported in 2006 and 12 in 2005. A summary of the sample deviations from-2007. are listed in Table 5-1. Only those incidences 1 that resulted in a loss of a planned sample have beenincluded.

6.0 QUALITY ASSURANCE AND QUALITY CONTROL 6.0 QUALITY ASSURANCE AND QUALITY CONTROL The REMP is designed to meet the quality assurance and quality control criteria of the NRC Regulatory Guide 4.1514' and 10CFR50 Appendix B"1°'. 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 Energy Northwest Quality Department performs audits of the REMP records and activities bi-annually. 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 2006 reader QC dosimeter results indicated satisfactory agreement for all four quarters and the annual processing results.

Spiked TLDs are submitted by Energy Northwest for processing along with the environmental TLDs. The processing results from these QA TLDs are used to demonstrate reader performance during environmental TLD processing. Quarterly spikes receive a target exposure of 22 mR and annual spikes receive a target exposure of 88 mR. The spiked dosimeters are processed with the field dosimeters to verify the accuracy and consistency of the environmental TLD evaluations.

Results were on average +0.29% above the known exposure rate. Results are listed 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. All 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.

2007 Annual Radiological Environmental Operating Report 6-1 Energy Northwest/Columbia Generating Station

I 6.2.1 Quality Control Activities for Sample Collection U Duplicate samples are routinely collected and submitted for'analysis. The duplicate samples- are in some cases blind, and in others they may be of a known origin. Duplicate samples are used to assess the repeatability of the sainple collection process and the precision of the analytical method.

U Chain of custody forms are kept through out the sampling and analysis proceiss to maintain sample control and traceability... -

6.2.2 Energy Northwest Environmental Services Quality Control Laboratory Sample Preparations Analytical balances used in the laboratory for sample preparations are calibrated every six months. Daily checks are performed prior to use on all analytical balances; these checks are documented on sample preparation forms and should span the range of intended use when checked. Devices used for volumetric measurements. of samples I

are periodically verified for accuracy with reagent grade water. I Analytical Instruments - Analytical instruments used for d6termining 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' practices for the different analytical instruments.

6.3 Sample Batch Quality Control . '.

Sample batches are analyzed along with sample blanks and known-addition samples (or spiked samples) as appropriate, and as dictated by the sample type. primary analytes of interest, anda method being used. The following is a summary of sample. batch QC activities..

Iodine-131.Cartridges - At least one blank charcoal cartridge was analyzed with each batch of samples assayed. At least one known-addition sample was analyzed with each batch. For the.

known-addition samples, the 356 keV peak of Ba- 133 was evaluated as a proxy for 1-131.

Gross Beta Filters - One or more blank filters were measured with each set of filters assayed. At least one unused blank AP filter and at least one known-addition AP filter (or spiked laboratory control sample) was analyzed with each batch. 3 2007 Annual Radiological Environmental Operating Report 6-2 Energy Northwest/Columbia Generating Station I

Aqueous Samples - In most cases, samples collected from the control locations were aiialyzed as blanks.: A known-addition sample was anajyzed with each batch of samples.

Gross Beta in Water - Blank. samples were prepared from reagent grade water and. analyzed with each batch of samples. At least one known addition sample was analyzed with each batch of gross alpha and gross beta samples. At least one replicate sample is prepared and analyzed inside of each batch..

Tritium in Water - Blank and low level known addition samples were measured with each batch. At least one replicate Sample was prepared and, analyzed inside'of each'batch.

6.4 Laboratory Intercomparison)Program Participation Participation in laboratory intercomparison studies is mandatory for all laboratories perfoirming analyses of CGS REMP samples. Intercomparison studies provide a consistent and effective means to, evaluate laboratoryperformance on sample analyses. Results from studies should fall within. the control limits specified'foi the study or corrective actions should. be performed.

Energy Northwest participated in the following intercomparison programs in 2007:

Since mid-1984, the results of the REMP analyses have beenpresepted as net results calculated from gross or total counts minus the observed background counts of the detection method.

Counting resIltsý for lowlevel 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.

Included for the first time in the 2007 report are also the analysis specific,. minimum detectable activity (MDA) values. Though similar in concept to the LLD, these value 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 ihi the sample foi'a positive identification ;to be made.
