1.0 Introduction This report has been prepared in compliance with Parts 50 of Title 10 of the Code of Federal Regulations (CFR), specifically 10 CFR 50.36a(a)(2) and Columbia Generating Station (CGS) Technical Specification 5.6.2. It includes a summary of the quantities of radioactive liquid and gaseous effluents and solid radwaste released from Columbia Generating Station during calendar year 2013. Effluent data is summarized on a quarterly basis.

Throughout this report, units of activity and dose are as defined in 10 CFR 20.1004, 20.1005, and Nuclear Regulatory Commission (NRC) Regulatory Guide 1.109-1977.

The United States National Council on Radiation Protection published Report #160 in 2009 which can serve to put radiation dose into perspective for the reader of this report. It was determined that the average yearly dose to a person living in the United States is 620 mrem from all sources. Of this, -50% is attributed to natural sources (radiation from gaseous radon, cosmic or space radiation, natural radioactive material in the ground, and natural radioactive materials in our bodies).

About 48% is attributed to diagnostic and therapeutic medical exposure. Radiation dose from nuclear power was grouped into a category comprising <0.1% of the total.

2.0 Liquid Effluents No planned releases of contaminated liquids from the liquid radwaste processing system were discharged to the Columbia River from Columbia Generating Station during calendar year 2013. The last discharge to the river from liquid processing took place in 1998.

In 2013, there were no known leaks to the environment of radioactive liquids.

3.0 Gaseous Effluents Routine Releases Gaseous effluents from Columbia Generating Station are released from three (3) principal release points:

Main Plant Vent -- mixed mode release Turbine Building - mixed mode release Radwaste Building -- ground level release The gaseous source terms from each release point are listed in Tables 3-1, 3-2, and 3-3. The activation gas argon-41 is included in these tables under fission gases to allow a match with the fission and activation gas totals of Table 3-4. Table 3-4 provides a summation of the total activity released, the average release rate, gross alpha radioactivity, and the estimated total error associated with the measurements of radioactivity in the gaseous effluents.

Columbia Generating Station 1

2013 Radioactive Effluent Report

Radioactivity measurements for gaseous effluent releases are performed for fission and activation gases by collecting the samples in a Marinelli beaker and analyzing them using gamma spectroscopy. Air is analyzed for tritium by collection of water vapor on a desiccant with subsequent distillation and liquid scintillation counting.

Particulates and iodines are sampled continuously and the sample media (particulate filters and charcoal cartridges) are analyzed weekly using gamma spectroscopy. Each quarter a chemical separation process is used to isolate strontium from the composite particulate filters and quantification is accomplished with liquid scintillation detection. The average energy per disintegration of fission and activation gases is not included in this report as it is not required by Technical Specifications and is not used for gaseous effluent release rate limit calculations.

When a radioisotope is not positively identified at levels greater than the Minimum Detectable Activity (MDA) or Minimum Detectable Concentration (MDC), a value of zero is used for release concentrations and offsite dose assessments. Table 3-6 contains the Lower Limit of Detection (LLD) values corresponding to the sampling methods and analytical instruments used for each principal radioisotope except carbon-14 (C-14 or 14C) as C-14 releases are estimated only.

Dose calculations were performed for releases using the NRC XOQDOQ and NRC Regulatory Guide 1.109 methodology (manually or with the GASPAR II computer program) and parameter values as described in the Offsite Dose Calculation Manual (ODCM). This methodology was based on Publication 2 of the International Commission on Radiation Protection released in 1959. As dose calculation methodology for soil resuspension is not described in the previously described documents nor as yet in the ODCM, it is described in detail in this report.

Quarterly and annual doses to the potentially highest-exposed Member of the Public (MOP) at and beyond the site boundary were calculated. In addition, quarterly and annual doses were calculated at actual resident locations identified in the annual land use census. ODCM limits are based on 10 CFR 20 and Appendix I to 10 CFR 50. The threshold for air dose applies to fission and activation gases and is ten (10) mrad for beta and five (5) mrad for gamma quarterly and twenty (20) mrad for beta and ten (10) mrad for gamma annually. The threshold for organ dose applies to iodine, tritium, and particulates with half-lives greater than eight days and is seven and a half (7.5) mrem quarterly and fifteen (15) mrem annually. For fission and activation gases the dose rate limits are less than or equal to 500 mrem per year to the whole body and less than or equal to 3000 mrem per year to the skin.

For iodines, particulates, and tritium the dose rate limit is less than or equal to 1500 mrem/year to any organ.

Dose calculations were also conducted for Members of the Public within the site boundary. The results are discussed and tabulated in Section 6.0.

Heating Steam Vents and Reliefs Building heat during the winter months is provided by either Seal Steam Evaporator B or by the Auxiliary Boiler. Vents and reliefs of this system to the atmosphere are unmonitored for licensed materials but the water used for steam is sampled Columbia Generating Station 2

2013 Radioactive Effluent Report

routinely while in use. The Auxiliary Boiler was not used during the 2013 heating season. At the start of the heating season, analysis of water in Seal Steam Evaporator B indicated 5.81 E-1 0 Curies/ml of tritium and this activity decreased during the season due to dilution with non-tritiated makeup water. Assuming the entire initial inventory (1.14E+07 ml) was released, the total release would be 6.63E-03 Curies of tritium through unmonitored vents of the heating steam system within and outside the main power block (Turbine, Radwaste, Reactor, and General Services buildings). These vents are unmonitored as this is an insignificant release point as defined in Revision 2 of NRC Regulatory Guide 1.21 as this activity comprises 0.013% of the total tritium released during 2013.

Cooling System Sediment Disposal Cell - Diffuse Source Cooling Tower and Spray Pond sediment are periodically sampled and disposed of on the surface of the ground in a fenced area within the site boundary authorized by the Washington State Energy Facility Site Evaluation Council. No materials are permitted to be placed in the Cooling System Sediment Disposal Cell (Disposal Cell) with licensed activity greater than the following limitations in Table 3a:

Storm Drain Pond (SDP) - Diffuse Source Columbia Generating Station was designed with an evaporation basin (Storm Drain Pond) within the Owner Controlled Area and described in the CGS National Pollutant Discharge Elimination System (NPDES) permit as "Outfall 2". The SDP receives storm water runoff, wastewater from potable and demineralized water production, intake air wash unit blowdown, and water from non-radioactive equipment dewatering, leakage, cleaning, and flushing activities. Since discovery of residual licensed radioactive material in the soil of the SDP in 1993, the pond has been fenced and posted in accordance with 10 CFR 20 requirements.

In August and September of 2011, environmental sampling of soil downstream of the outfall to the Storm Drain Pond found low levels of Mn-54, Co-58, Co-60, Zn-65, Cs-134, and Cs -137. The measured activity values were reported in the 2011 Annual Radiological Environmental Operating Report. Fe-55, Ni-63, and Sr-90 results were less than the MDC values. Except for tritium, no activity greater than the Minimum Detectable Activity (MDA) was found in the flow-proportional outfall discharge samples in 2013. Soil sampling was performed in June, 2013.

The source of the low level activity was determined to be monitored and controlled gaseous effluent releases. The recapture of activity released is from a) the precipitation washout/rainout of released activity, b) cooling tower and spray pond plume drifting north to northwest over the gaseous release ducts and scavenging activity, and c) the re-condensation of water vapor in gaseous effluents.

For the purpose of evaluating the potential dose impact to Members of the Public, dose estimates were based on the maximum activity (shown in Table 3b) detected in 2013.

A review of the exhaust flow rate shows that the door was open from 0556 hr on 3/16/13 and continued to 4/3/13. The flow rate recorded in the upper portion of the duct showed a decrease from 73324 cfm to 64960 cfm when the door opened.

The reactor building Heating, Ventilation, and Air Conditioning (HVAC) System and the Offgas Post Treatment System both discharge into the middle of this vertically-oriented release duct. Normally, the path of least resistance is out the top of the duct. When this maintenance access door was open, approximately 11.4% of what would have gone out the designed (upper) exit of the stack was exiting horizontally out of the base of this vertical release duct.

This was a monitored release as a representative sample of the air in the exhaust duct during this time was being taken by a 32-nozzle sample array.

This duct is considered a mixed mode release point as defined by NRC Regulatory Guide 1.111, Revision 1, 1977. The NRC Computer code XOQDOQ is used by Columbia Generating Station to determine dispersion and deposition values.

Plume buoyancy is calculated with inputs of the heat emission rate (the same for both the door exit and the upper release point), the vertical exit velocity (different for the two exit points), and the horizontal wind speed (same for the two exit points).

XOQDOQ then determines the effective stack height at locations of interest. To demonstrate compliance with routine ODCM Requirements for Operability (release limitations), the exhaust flow rate measured by the flow elements in the upper portion of the vertical release duct was adjusted to reflect the actual release flow rate (corrected for loss at the door). As such, the activity released through the open door was accounted for.

Abnormal Release - Seal Steam Relief Valve On 9/22/13, an unmonitored, abnormal gaseous release (AR-CR 294265) occurred.

It was noted that a seal steam relief valve (SS-RV-9A) was lifting and not reseating due to leakby of pressure control valve BS-PCV-18A. The relief valve is on the shell side of Seal Steam Evaporator A (SS-EVAP-1 A) and exhausts at the roof of the building. Evaporator A is supplied by Feedwater from the Main Condensate system downstream of the 5th Stage Feedwater heaters (the water has passed through the condensate filter demineralizers and is preheated). The relief valve was open for approximately 12.76 hours8.796296e-4 days 0.0211 hours 1.256614e-4 weeks 2.8918e-5 months and water loss was estimated at 71.62 gallons per minute resulting in 54,832 gallons released. Samples of this system at the time of the release showed Co-60, Cs-137, and H-3. The activity present and the total curies released is shown in Table 3c.

From this, the dispersion and deposition values were derived. As winds were from the S to SSW, only Members of the Public in the N to ENE sectors were affected.

Carbon-14 Carbon-14, with a half-life of 5,730 years, is a naturally occurring isotope of carbon produced by cosmic ray interactions in the atmosphere. When C-14 decays it emits a beta particle of varying energies up to 0.156 MeV with an average energy of 0.049 MeV. As a result of this low energy, the air and inhalation doses are insignificant. Nuclear weapons testing in the 1950s and 1960s significantly increased the amount of C-14 in the atmosphere. C-14 is also produced in commercial nuclear reactors, but the amounts produced are much less than those produced naturally or from weapons testing.

Although 10 CFR 50.36a has always required reporting the principal nuclides released, carbon-14 had been exempted because of the large quantity that existed naturally in the environment. However, following release of Revision 2 of Regulatory Guide 1.21 (Measuring, Evaluating, and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste), the NRC recommended that U.S. nuclear power plants evaluate whether C-14 is a "principal radionuclide", and if so, report the amount of C-14 released.

A radionuclide is considered a principal radionuclide if it contributes either (1) greater than 1 percent of the 10 CFR Part 50, Appendix I, design objective dose, or (2) greater than 1 percent of the activity of all radionuclides in the type of effluent Columbia Generating Station 6

2013 Radioactive Effluent Report

being considered. This implementation of "primary radionuclides" ensures both (1) radionuclides that are present in relatively large amounts but that contribute very little to dose, and (2) radionuclides that are present in very small amounts but that have a relatively high contribution to dose are appropriately included in the annual effluent report.

At Columbia Generating Station, improvements over the years in effluent management practices and fuel performance have resulted in a significant decrease in radioactive gaseous emissions. As a result, C-14 has become a "principal radionuclide" for the gaseous effluent pathway at Columbia Generating Station. Columbia Generating Station's 2013 Annual Radioactive Effluent Release Report (ARERR) contains estimates of C-14 radioactivity released in 2013, and estimates of public dose resulting from the C-14 effluent.

Since there were no liquid tank releases to the river, there was no dose to a Member of the Public from liquid releases. The quantity of gaseous C-14 released to the environment is estimated by use of a C-14 source term scaling factor based on power generation. Electric Power Research Institute (EPRI) Technical Report 1021106 estimates the production of C-14 at approximately 5 CVGWth - yr or 17.8 Ci/yr at rated power. Based on Columbia Generating Station power production for 2013 and assuming that all C-14 generated is released in gaseous effluent, then the total C-1 4 emission is calculated to be 15.4 Ci.

C-14 releases in BWRs occur primarily as a mix of organic carbon and carbon dioxide released from the offgas system. Since Columbia operates with a reducing chemistry, most, if not all, of the C-14 species initially produced are organic (e.g.,

methane). As a general rule, C-14 in the primary coolant is essentially all organic with a large fraction as a gaseous species. When the reactor coolant or offgas is exposed to an oxidizing environment (e.g. in the offgas treatment system or during shutdowns or refueling), a transformation from the organic to an inorganic chemical form can occur.

Public dose estimates from airborne C-14 are performed using dose models from NRC Regulatory Guide 1.109, Revision 1, 1977. The estimated C-14 dose impact from Columbia Generating Station in 2013 was well below the 10 CFR 50, Appendix I, ALARA design objective (i.e., 15 mrem/yr per unit) as shown in Section 6 of this report.

Out-of-Service Effluent Monitors The ODCM requires submittal in this report of the reasons why any effluent monitors were not returned to a functional status within 30-days of failure. During 2013, there were no ODCM-related effluent monitors out of service longer than 30 days.

Calculated quarterly doses cannot be directly compared to the annual doses. Each above listed quarterly dose is the highest calculated dose based on a number of variables. Variables that make comparison difficult include location, meteorological data (quarterly joint frequency distribution (JFD) tables vs. annual JFD tables), receptor age, target organ, and characteristics of the emitted radionuclides.

This table shows the highest air dose or organ dose for either a hypothetical resident at the site boundary or an actual resident within a 5-mile radius.

The pathways of exposure considered at the site boundary are the plume exposure, ground exposure, and inhalation pathways only and does not include dose from non-depositing C-14. The highest organ dose received from all gaseous effluent releases (including C-14), for the full year of 2013, for residents identified in the Land Use Census, and for all pathways of exposure identified, was for a resident (child) at 4.26 miles ESE. The highest organ dose for the plume exposure, ground exposure, garden produce ingestion, and inhalation pathways was 2.13E-2 mrem which is 0.14% of the 15 mrem 10 CFR 50 Appendix I guideline.

Measurement errors are sample-specific. The values reported represent an approximate overall error. Some of the contributors of this error are measurements associated with estimating the sample volume, the exhaust duct flow rates, plateout factors, charcoal cartridge efficiencies, temperatures of sample lines, buildings, and ambient air, barometric pressure, sample line vacuum, run time estimates, anisokinetic correction factors where needed, and gravimetric, gamma spectroscopy, and liquid scintillation analysis errors.

MDA = Less than the "a posteriori" minimal detectable activity (microcuries per unit mass or volume).

ODCM release rate limits are based on dose rate. For fission and activation gases the dose rate limits are less than or equal to 500 mrem/year to the whole body and less than or equal to 3000 mrem/year to the skin. For 1-131, particulates, and tritium the dose rate limit is less than or equal to 1500 mrem/year to any organ.

The ODCM dose factors and the highest site boundary dispersion value for each period were used in the calculation.

5.0 Meteorological Data The meteorological data contained in Tables 5-1 through 5-11 was obtained from a meteorological tower located 762 meters (2500 feet) west of Columbia Generating Station. Data was recovered from two sets of redundant instruments on the tower at the 10 meter (33-foot) and 75 meter (245-foot) levels. The meteorological data is a composite file generated from the automated data recovery systems for the calendar year 2013. Data is archived on the Energy Northwest Local Area Network.

Meteorological data recovery for 2013 was 99.2% from the 33-foot level and 99.1%

from the 245-foot level. Redundant wind and temperature sensors are installed at both levels of the meteorological tower. Data from the two systems can be combined to permit maximum data recovery for defined date ranges.

The data in Tables 5-1 through 5-8 provide joint frequency distributions (JFD) at the 10-meter and 75-meter levels by quarter for 2013. These tables show the total hours at various wind speeds for each sector and stability class. The NRC stability classes A through G, eleven wind speed categories, and the 16 wind direction sectors were used to prepare each joint frequency table. Tables 5-9 and 5-10 provide the annual joint frequency distributions at the specified heights for 2013.

Table 5-11 provides a joint frequency distribution from the 10 meter wind instruments during daylight hours of the growing season. The threshold value for daylight was chosen at solar irradiance of greater than 5 watts/m 2. This JFD table was used for C-1 4 dose estimates from ingestion pathways.

Wind speed is measured in miles per hour in the tables and speeds below 1.0 MPH were recorded as calms.

There are a number of atmospheric factors which affect dispersivity, but are not modeled in the CGS estimates of dispersion and deposition. Those conditions which were measured or documented at the Hanford Meteorological Station during 2013 were: snow (2.0 inches total in January and December), total precipitation (5.38 inches), freezing rain (8 days), dust or blowing dust (4 days), fog (41 days),

and thunderstorms (13 days).

Rainfall as recorded at the Columbia Generating Station meteorological tower was 3.6 inches.

6.0 DOSE ASSESSMENT -- IMPACT ON MAN Liquid Effluents - There were no liquid discharges from the radwaste processing system to the Columbia River during calendar year 2013.

Gaseous Effluents - The NRC GASPAR II computer code was used to calculate doses at and beyond the site boundary using quarterly and annual meteorological data and site-specific variables as required and defined in the ODCM. Table 6-1 shows the highest calculated doses at the site boundary and beyond the site boundary. Table 6-1 also shows the quarterly and annual dose for the nearest and highest exposed resident identified in the land use census. Table 6-2 provides the population collective dose within a 50-mile radius. These values were obtained from the As Low As Reasonably Achievable (ALARA) annual integrated population dose summary (in person-rem) of the GASPAR computer code output file. Table 6-2 also provides the annual average individual doses associated with each pathway.

These values were obtained by dividing the ALARA integrated dose (person-rem) by the estimated year 2010 50-mile population (448,383) and converting to mrem.

During the growing season, Columbia Generating Station conducts a five-mile land use census to determine the locations of nearest residents, gardens, and milk animals or other livestock out to five miles in each sector. The 2013 Land Use Census did not identify broad leaf vegetable gardens or milk animals within the 5-mile radius. Cattle and horses were observed within 5-miles. As substantial commercial fruit orchards and corn crops were observed in all eastern sectors with residents, it was assumed that these crops were being consumed by the residents.

Outside the 5-mile radius, dose is estimated for residents at 7.33 miles ESE due to a cow-milk ingestion pathway. The GASPAR code consumption rates were revised to reflect these differences.

Carbon-14 Carbon-14 (in the form of 14CO 2) is a non-depositing, gaseous effluent, and enters the food chain through plant photosynthesis. Since Columbia Generating Station is a continuous release plant, normally, offsite dose is based on meteorological data throughout the year. For 14C dose analysis, however, a Joint Frequency Distribution (JFD) table of atmospheric data is developed based on daylight hours (solar irradiance > 5 watts per square meter) during the growing season of both garden produce and pasture grass for beef (April 15th through October 1 5 th). The JFD table was used as input into the NRC XOQDOQ computer code from which dispersion estimates were obtained. This method provides a more accurate method of determining the average air concentration of 14C02 at locations of interest during times of photosynthesis.

Both inhalation and ingestion pathways contribute to dose from 14C. The inhalation dose estimate assumes a full year 14C inhalation of both 14CH 4 and '4CO2. The ingestion pathway assumes 4C ingestion from 14CO 2 incorporation into vegetation, meat, and milk during daylight hours of the growing season.

Dose from carbon-14 is shown in Tables 6.0-C through 6.0-H. The highest dose from 14C calculated was for the resident at 4.26 miles in the ESE sector. The annual dose to the potential maximally exposed individual (child living at this Columbia Generating Station 53 2013 Radioactive Effluent Report

location) from gaseous releases of 14C is 2.02E-02 mrem to the critical organ (bone) and 4.01 E-03 mrem to the total body. The available dose pathways at this location from 14C were inhalation and the ingestion of garden produce (fruits, grains, and non-leafy vegetables). Dose from 14C is included in Tables 6.0-C through 6.OH of this section.

Disposal Cell - Diffuse Source As stated earlier in this report, Cooling Tower and Spray Pond sediment are periodically sampled and disposed at a location within the site boundary authorized by the Washington State Energy Facility Site Evaluation Council. Due to the arid and windy conditions at CGS, resuspension of soil in the atmosphere could contribute dose to a Member of the Public onsite or offsite.

Normally the Offsite Dose Calculation Manual (ODCM) is used to determined dose to a Member of the Public in the unrestricted area. It contains the methodology and parameters needed to assess the offsite dose to a Member of the Public resulting from liquid and gaseous effluents. Regulatory Guide 1.109 (RG109) details the methodology for those exposure pathways that are expected to have the highest impact to a member of public.

Resuspension of particulate matter and the resultant dose is not addressed in RG109. It was therefore necessary to develop the appropriate equations for estimation of dose due to particulate resuspension. The exposure mechanisms examined were:

" Inhalation

" Indirect and direct ingestion

" Ground Plane

" Vegetation Consumption

" Beef Consumption Conservative assessment of the above exposure pathways reveals that the resuspension of soil is not a significant contributor to the dose received by a Member of the Public, either onsite or offsite.

Details of the assumptions, equations and parameters used are discussed in the following sections.

Soil Resuspension Model There are several approaches to dealing with the issues of soil resuspension.

Resuspension factor in units of 1/m which is the ratio of the air concentration to the surface deposition.

Columbia Generating Station 54 2013 Radioactive Effluent Report

" Resuspension rate in units of 1/sec describing the fraction of deposited material resuspended per unit time.

Resuspension velocity (m/sec) which is a parallel to the deposition velocity used in determining ground plane deposition.

" Mass loading factor in units of kg-soil/m 3-air.

The resuspension factor, resuspension rate and resuspension velocity are dependent on two parameters (theoretical or empirical) which vary over a wide range. The mass loading factor approach is the methodology used in RESRAD as it uses a single parameter that can be easily measured directly should the need arise.

The dose models of this report reflect the RESRAD approach for resuspension of particulates which assume the mass loading factor remains constant over time.

This implies a continuous resuspension process and therefore the airborne release concentration remains constant at the source. RESRAD uses a default mass loading value of 100 PIg/m 3. This is a conservative value to account for short periods of high mass loading such as might occur during dust storms at CGS. It also takes into account sustained periods of soil resuspension resulting from excavation or farming activities.

Depletion of the source activity due to weathering and radiological decay processes is ignored. Also the dilution of redeposited soil by local soil is not considered.

These simplifications are justified based on wide variation in reported and observed values of the parameters associated with the aforementioned physical processes.

The necessary site specific values could be determined for more sophisticated modeling purposes. However the estimated doses are sufficiently conservative and low enough to make such an effort unnecessary.

Dose From Inhalation of Resuspended Soil The dose due to inhalation of resuspended soil is given by:

DINaij = x/Q C, pair Rair BRa DFAaij Where DINaij Is the dose due to inhalation of resuspended soil in mrem for age group "a",

nuclide "i" and organ "j". The inhalation dose factors are taken from Tables E-7 to E-10 of Reg Guide 1.109.

x/Q Is the atmospheric dispersion for ground level releases at the location of interest in sec/m 3.

Ci Is the concentration in soil of radionuclide "i" in pCi/kg-soil at the Disposal Cell area. Values are listed in Table 6a.

Columbia Generating Station 55 2013 Radioactive Effluent Report

pair Is the mass loading or concentration of particulate matter in air in kg-soil per m3-air. Both NCRP Report No. 76 and the RESRAD User Manual recommend a value of 100 pg/m3. The RESRAD documentation recommends this as a conservative default value that takes into account short periods of high mass load and sustained periods of normal activity as on a typical farm or excavation site.

Rair Is the hypothetical release rate in m3-air/sec. It is based on considering the Disposal Cell as a continuous release source. (1.0 m3-air/sec)

BRa Is the breathing rate for age group "a" in m3/yr taken from Table E-5 of Reg Guide 1.109.

DFAaij Is the inhalation dose factor for age group "a", nuclide "i" and organ "j" in units of mrem/pCi. These dose factors are taken from Tables E-7 to E-1 0 of Reg Guide 1.109.

Dose Due to Ingestion of Resuspended Soils Ingestion of resuspended soil can take place indirectly or directly.

Indirect ingestion occurs when suspended particles are inhaled, trapped in mucous and subsequently transported from the respiratory track to the gastrointestinal track.

Direct ingestion refers to soil that is orally consumed deliberately or accidentally.

Indirect Ingestion Indirect ingestion (inhalation-ingestion) readily occurs in environments of high airborne soil concentration resulting from natural or anthropomorphic processes.

Examples include dust storms, agricultural tillage and soil excavation.

Estimates of indirect soil ingestion rates vary widely. The EPA Exposure Factor Handbook published in 1997 suggested a soil intake rate for adults engaged in outdoor yard work of 480 mg/da. The 2011 EPA Exposure Factor Handbook suggests a general population upper percentile ingestion rate of 200 mg/da. The former value (480 mg/da) considers unintentional consumption during periods of high airborne concentrations of resuspended soil. Such cases may occur during mechanical excavation or dust storms at the Columbia Generating Station site.

Dose due to indirect ingestion (inhalation-ingestion) of resuspended soil is given by:

Dlail = x/Q Ci (pair/ pSOS) Rair Usoila DFlaij Where:

D"aij Is the dose due to ingestion of resuspended soil in mrem for age group "a",

nuclide "i" and organ "j". The ingestion dose factors are taken from Tables E-11 to E-14 of Reg Guide 1.109.

Columbia Generating Station 56 2013 Radioactive Effluent Report

x/Q Is the atmospheric dispersion for ground level releases at the location of interest in units of sec/m3.

Ci Is the concentration in soil of radionuclide "i" in pCVkg-soil at the SDP area.

Values are listed in Table 6a.

pair Is the mass loading or concentration of particulate matter in air in kg-soil per m3-air. Both NCRP Report No. 76 and the RESRAD User Manual recommend a value of 100 pg/m3. The RESRAD documentation recommends this as a conservative default value that takes into account short periods of high mass load and sustained periods of normal activity on a typical farm.

p so Is the bulk soil density in kg-soil/m 3-soil (1.5 gm/cc - Health Physics Handbook)

Rair Is the hypothetical release rate in m3-air/sec. It is based on considering the Disposal Cell as a continuous release source. (1.0 m3-air/sec)

Uso" Soil intake rate in kg-soil/yr. There is a wide range of values suggested for soil ingestion rates. A value of 480 mg-soil/da is the suggested ingestion rate for an adult engaged in outdoor activity. Taken from the EPA Exposure Factor Handbook, 1997.

DFlaij Ingestion dose factor for for age group "a", nuclide "i" and organ "j" in units of mrem/pCi. These dose factors are taken from Tables E-11 to E-14 of Reg Guide 1.109.

Direct Ingestion Direct ingestion considers the intentional or unintentional oral consumption of soil.

Unintentional ingestion can occur from the adherence of soil to fruits, vegetables, etc. Deliberate ingestion - known as soil pica - is a common occurrence among children with consumption reaching as high as 1,000 to 5,000 mg/da for short periods of time.

Very high soil ingestion or geophagy is usually associated with cultural practices resulting in ingestion rates as high as 50,000 mg/da. However such high consumption rates are brief and surface soils are not usually the primary source of the ingested material.

Potential dose due to soil-pica and geophagy is likely to be higher than that of the inhalation-ingestion mechanism as these behaviors involve the direct ingestion of soil. Any resuspended particulates transported into the area will be mixed with and subsequently diluted by clean local soil. Nevertheless this dilution mechanism is not taken into account in this assessment thus providing an additional level of conservatism.

Columbia Generating Station 57 2013 Radioactive Effluent Report

For purposes of this assessment doses have been estimated for soil consumption rates of 5,000 mg/da. This value is taken from the EPA Exposure Factor Handbook, 2011 and represents the upper limit of observed soil pica in children. This rate of ingestion is assumed to be sustained through the year.

Geophagy is not considered as the periods of high soil intake are short in duration.

The annual soil consumption would not approach that of the consumption for child pica which assumes a continual 5,000 mg/da (- 1.8 kg/yr) ingestion rate.

In considering oral soil ingestion it is assumed that source of the ingested material is the ground itself. Thus deposition and buildup of transported resuspended soil onto the ground plane must be taken into account.

The dose due to direct soil ingestion is given by:

D =D /Q air P

airi(Il-exp(- 'i t)]

psoil Is the bulk soil density in kg-soil/m 3-soil (1.5 gm/cc - Health Physics Handbook)

Tr°'o Is the thickness or depth in meters of the top layer of soil available for ingestion in meters (1.5 cm - RESRAD).

DFlaij Ingestion dose factor for age group "a", nuclide "i" and organ "j" in units of mrem/pCi. These dose factors are taken from Tables E-1 1 to E-14 of Reg Guide 1.109.

Other Dose Pathways The methodologies for calculating dose from ground plane, vegetation ingestion and meat ingestion are those of Regulatory Guide 1.109, Appendix C, Equations C-5, C-12 and C-13. The source term is taken from Table 6a.

Dose Summary Source Term The limit of activity authorized to be deposited at the Disposal Cell was presumed to be homogenously distributed over the entire area. This was considered to be a continuous release source with resuspended soil airborne concentrations described by the mass loading factor. The assumption of continuous conditions is consistent with the approach used by RESRAD.

The release rate of Table 6a is based upon the hypothetical release rate of 1 m3/sec and the RESRAD suggested mass loading factor of 100 pg-air/kg-soil.

The infant and child age groups were excluded from consideration as they would not be expected to be present on site. Estimates were based on the teen age group as the most radiosensitive group.

For offsite locations, dose estimates were evaluated for Members of the Public at locations identified in the most recent land use census with the highest dispersion and deposition values as well as for those with more ingestion pathways than others. Higher dose values resulted for residences located at 4.95 miles ENE and at 4.26 miles ESE. Vegetation and cattle meat pathways were considered present at 4.95 miles ENE and the vegetation pathway at 4.26 miles ESE.

For onsite locations where actual Members of the Public are known to have been located, the highest organ dose was found to be 1.66E-09 mrem to the liver. The highest total body and thyroid doses were 1.46E-09 mrem and 1.34E-09 mrem respectively. This is a result of an estimated occupational exposure time of 2080 hours0.0241 days 0.578 hours 0.00344 weeks 7.9144e-4 months at the Ashe Substation.

For hypothetical situations, should the National Guard be stationed at 0.5 miles North of the site, the highest organ dose was found to be 6.98E-09 mrem to the liver. The highest total body and thyroid doses were 6.15E-09 mrem and 5.66E-09 mrem respectively. This is a result of the hypothetical exposure time of 1 year (8760 hours0.101 days 2.433 hours 0.0145 weeks 0.00333 months ) of continuous residence.

The highest offsite dose to a Member of the Public was found to be at 4.26 miles ESE and was well below the 10 CFR 50 Appendix I limits. The highest organ dose was 1.24-011 mrem to the liver. The highest total body and thyroid doses were 1.04E-1 2 mrem and 1.01 E-1 1 mrem. The highest exposure pathways are ground plane and direct consumption of soil. Dose due to the consumption of produce and animal products was on the order of 1.1OE-1 1 mrem or less.

Use of published default values and maximizing assumptions has resulted in a very conservative dose assessment. The lack of site specific empirical data and considering the parameter uncertainty associated with sophisticated models justifies this conservative approach. It provides a bounding estimate of exposure to a Member of the Public. The actual doses to a Member of the Public are most likely 2-3 orders of magnitude less than the doses of Tables 6c, 6d, and 6e.

Storm Drain Pond (SDP) - Diffuse Source As the Storm Drain Pond is both within the Controlled Area and is fenced and posted, external exposure from activity in the ground or internal exposure from ingestion of food grown in the soil of the Storm Drain Pond is prevented.

The remaining potential routes to a Member of the Public.

" External exposure from standing on the ground above areas contaminated from resuspended activity.

" Ingestion of contaminated ground or river water as a result of vertical migration to the unconfined aquifer followed by horizontal movement toward the closest surface water (Columbia River).

" Inhalation and ingestion of resuspended radioactivity.

Ingestion of Potentially Contaminated Water Relative to the potential ingestion of contaminated ground water, generally, the radionuclides of concern are H-3, Sr-90, and Cs-137. These three radionuclides are fairly representative in terms of sorption characteristics of those found in probable plant effluents. Tritium does not sorb onto soil particles at all, strontium is an intermediate sorber, and cesium strongly sorbs to soil particles. It was observed from previously-measured Storm Drain Pond activity that Co-60 sorption to soil is similar to that of Cs-137.

The CGS Final Safety Analysis Report calculates the transport time for these nuclides to the river for a ground release assuming no holdup or migration time through the soil to groundwater. This is a large assumption as sorption in soil has been observed to be quite high. The transport time from the unconfined aquifer to the river takes into account decay, dispersion, and sorption on the aquifer media.

The transport time to the river for H-3 is 5.2 years, Sr-90 is 230 years, and Cs-1 37 is 2300 years. The concentration reduction factors are 7.7E5, 1.8E8, and 5.8E28 respectively based on dispersion, sorption, decay, and dilution.

By the time it would take to reach the river, the nuclide concentrations in Table 6f would not be detectable.

Based on the 2013 Radiological Environmental Monitoring Program (REMP) sampling of the water entering the SDP, Table 6g was constructed to project the concentration of tritium (H-3) reaching the Columbia River should the tritium reach the groundwater instantaneously without any reduction in concentration.

Table 6g - Tritium Concentration Reduction At SDP Concentration At Columbia Outfall reduction River (pCi/liter) factor (pCi/liter)

Maximum H-3 Concentration 4.95E+03 7.70E+05 6.43E-03 Average H-3 Concentration 9.87E+02 7.70E+05 1.28E-03 Tritium is a naturally-occurring radionuclide produced from cosmic radiation interactions with gases in the upper atmosphere. The worldwide inventory of natural tritium is estimated at 2.6E+1 9 pCi (National Council on Radiation Protection and Measurements Report #62). Levels of tritium in the Columbia River are monitored by the CGS REMP and documented in the Annual Radiological Environmental Operating Report (AREOR). The 2013 AREOR notes that tritium results for plant intake and river/drinking samples were below the analysis method a priori LLD (300 pCi/liter). The projected values in Table 6g are 10,000 to 100,000 times lower than both the REMP LLD and the EPA standard for drinking water (<

20,000 pCi/liter). With further dilution of the SDP tritium with Columbia River water, there would be insignificant dose above background values from drinking water taken from the Columbia River. There are currently no wells used for drinking water in the shallow (unconfined) aquifer. Use of water from future wells in this aquifer would be restricted due to the tritium contamination from DOE activities which are currently greater than drinking water standards.

Resuspension of SDP activity The dose estimates in this section for the Storm Drain Pond follow the methodology described above for the Disposal Cell. The SDP soil is normally moist due to Columbia Generating Station 64 2013 Radioactive Effluent Report

routine water intrusion. This along with the vegetation cover reduces the resuspension of activity. To be conservative, the ground plane, inhalation, indirect ingestion and direct ingestion exposure pathways from resuspension were considered to be present at all locations. The infant and child age groups were excluded from onsite consideration as they would not be expected to be present.

The onsite age group was assumed to be teen as this would be the most radiosensitive group. Based on this, the dose to a Member of the Public due to onsite activity was well below the Appendix I limits. Since no soil samples were taken in 2013 and the input was determined to be due to recapture of released activity during routine operations, the concentration of nuclides is assumed to have not changed significantly. Dispersion and deposition values used in the previous analysis were 5-year (2008 - 2012) averages. Potential dose to actual and hypothetical Members of the Public both onsite and off site was calculated using the most recent land use census and shown below in Table 6h.

In this case, the highest organ dose was found to be 6.05E-07 mrem to the skin. The highest total body and thyroid doses were 5.20E-07 mrem and 5.15E-07 mrem respectively.

Offsite dose to a Member of the Public was evaluated and shown in Table 6i and 6j.

In addition to the pathways considered for onsite exposure, ingestion pathways of garden produce and beef meat were considered based on the 2013 land use census. The offsite dose to a Member of the Public was found to be well below the Appendix I guidelines. The Total Dose listed in the following two tables is the addition of the highest organ dose from each pathway although the highest dose from each pathway is age specific. As a result, the Total Dose does not represent a real person. For example, an infant does not consume the same quantity of beef as an adult. The highest organ dose was found to be 1.08E-09 mrem to the skin.

The highest total body and thyroid doses were both 9.22E-1 0 mrem. The highest exposure pathways are ground plane and inhalation. Dose due to the consumption of produce and animal products was on the order of 1.29E-1 0 mrem or less.

From this, the dispersion and deposition values were derived. As winds were from the S to WSW, only Members of the Public in the N to ENE sectors would have been affected. As this release occurred after normal business hours, it is unlikely that a Member of the Public would have been in the N to ENE sectors of the site.

Estimates of dose from Seal Steam is shown in Tables 6.0-C through 6.0-E.

Dose to Onsite Members of the Public The term "Member of the Public" includes all persons who are not occupationally associated with the plant. This category does not include employees of the utility, its contractors or vendors. Also excluded from this category are persons who enter the site to service equipment or to make deliveries. This category does include persons who use portions of the site for recreational, occupational or other purposes not associated with the plant.

Columbia Generating Station 66 2013 Radioactive Effluent Report Columbia Generating Station 66 2013 Radioactive Effluent Report

Dose was evaluated to Members of the Public within the owner controlled area as well as beyond the site boundary. For those within the site boundary, the estimates included visitors to either the plant or the firing range as well as those that worked at the Industrial Development area in the E and ESE sectors and at the DOE 618-11 burial site in the W and WNW sectors. The maximum dose from gaseous effluents to these individuals was estimated assuming exposure to the plume, inhalation, and ground deposition pathways.

The following table (6.0-A) shows estimated dose to Members of the Public from gaseous effluents and direct radiation exposure within the site boundary of Columbia Generating Station for the total indicated hours spent at each location.

Table 6-1 Summary of Doses from Gaseous Effluents The information contained in Table 6-1 is provided consistent with all previous effluent release reports from Columbia Generating Station. Dose from carbon-14 is not included in these summary tables. Dose to Members of the Public from C-14 is detailed in the previous section. C-14 does not contribute to air dose, inhalation dose from C-14 is so small that it is not calculated by the NRC GASPAR computer code, and there are no ingestion pathways for hypothetical Members of the Public at the site boundary. Quarterly and annual dose estimates in this table are made with joint frequency distribution and dispersion and deposition values derived from meteorological data specific to each time period, whereas C-14 dose estimates provided earlier are made with joint frequency distribution and dispersion and deposition values derived from meteorological data during periods of photosynthesis in the defined growing season.

The first six tables in this section show maximum estimated exposure and dose at and beyond the site boundary. No residents were observed at the site boundary.

The maximum exposure and dose beyond the site boundary is estimated for locations with actual residents.

For each time period, the dose estimate uses the radionuclide mix and release rate for that period along with an estimate of the dispersion in air and deposition on ground and vegetation calculated by the NRC computer code XOQDOQ using actual meteorological conditions during the respective quarters. The dose estimate of the NRC computer code GASPAR uses, as base methodology, NRC Regulatory Guide 1.109 (1977) which includes the prospective dose component arising from retention in the body beyond the period of environmental exposure.

These values are derived by dividing the 50-mile population collective doses by the population within 50 miles of Columbia Generating Station (448,383). The population estimate is based on the 2010 census conducted by the United States Census Bureau tabulated/compiled by the Washington State Office of Financial Management, Small Area Estimate Program. The Maximum Organ was the skin.

8.0 REVISIONS TO THE PROCESS CONTROL PROGRAM (PCP)

There were no revisions to the Process Control Program, SWP-RMP-02 in 2013.

9.0 NEW OR DELETED LOCATIONS FOR DOSE ASSESSMENTS AND/OR ENVIRONMENTAL MONITORING LOCATIONS 9.1 There were no major changes observed in the 2013 Five-Mile Land Use Census (LUC). No broad leaf vegetation was observed in any gardens or fields within the 5-mile radius. However, because of the fruit, corn, and other crops being commercially grown in the area, the garden produce pathway is assumed for all residents. Dose from the cow-milk pathway was estimated for a resident at 7.33 miles ESE even though outside of the five-mile radius and as a result, estimates of gaseous effluent dispersion and deposition based on a straight-line Gaussian plume model will have significant error due to intervening topographic features.
