1. lntr~duction Results of the Radiological Environmental Monitoring Program for the Comanche Peak Nuclear Power Plant (CPNPP) for the year 2012 are contained within this report. This report covers the period from January 1, 2012 through December 31, 2012 and summarizes the results of measurements and analysis of data obtained from environmental samples collected during this same timeframe.

CPNPP consists of two pressurized water reactor units, each designed to operate at a power level of about 1250 megawatts (electrical).

The Station is located on Squaw Creek reservoir in Somervell and Hood counties, about forty miles southwest of Fort Worth, Texas. Unit I received a low power operating license February 8, 1990 and achieved initial criticality on April 3, 1990. A full power license for Unit I was issued on April 17, 1990 and commercial operation was declared on August 13, 1990. Unit 2 achieved initial criticality on March 24, 1993 and commercial operation was declared on August 3,1993.The United States Nuclear Regulatory Commission (USNRC) regulations require that nuclear power plants be designed, constructed, and operated to keep levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA). To assure that these criteria are met, each license authorizing reactor operation includes technical specifications governing the release of radioactive effluents.

In-plant monitoring is used to assure that thes predetermined release limits are not exceeded.

However, as a precaution against unexpected and undefined processes that might allow undue accumulation of radioactivity in any sector of the environment, a program for monitoring the plant environs is also included.Sampling locations were selected on the basis of local ecology, meteorology, physical characteristics of the region, and demographic and land use features of the site vicinity.

The radiological environmental monitoring program was designed on the basis of the USNRC Branch Technical Position "& Aglable RAdtoogga Envj tAM Monitoring Program" on radiological environmental monitoring issued by the Radiological Assessment Branch, Revision 1 (November 1979), the CPNPP Technical Specification "Te i S~ifigagos oCognhe Peak Nuclear Power PMWnt Units 1 and 2" and the XPSES Offsite Dose Calculation Manual" (ODCM).5 In 2012, the Radiological Environmental Monitoring Program included the following: " The measument of ambient gamma radiation by Optically Stimulated Luminescent dosimetry;" The determination of airborne gross beta, gamma emitters, and lodine-131;" The determination of tritium and gamma emitters in surface water;" The determination of gross beta, tritium. Iodine- 131, and gamma emitters in drinking water," The determination of tritium and gamma emitters in ground water;" The determination of gamma emitters in sediment and fish;" The determination of gamma emitters in food products and;" The determination of gamma emitters and Iodine- 131 in broadleaf vegetation.

The regulations governing the quantities of radioactivity in reactor effluents allow nuclear power plants to contribute, at most, only a small percentage increase above normal background radioactivity.

Background

levels at any one location are not constant but vary with time as they are influenced by external events such as cosmic ray bombardment; weapons test fallout, and seasonal variations.

Thes levels also can vary spatially within relatively short distances reflecting variations in geological composition.

To differentiate between background radiation levels and increases resulting from operation of CPNPP, the radiological surveys of the plant environs were divided into pre-operational and operational phases.The pre-operational phase of the program provided a general characterization of the radiation levels and concentrations prevalent in these areas prior to plant operation along with an indication of the degree of natural variation to be expected.

The operational phase of the program obtains data which, when considered along with the data obtained in the pre-operational phase, assists in the evaluation of the radiological impact of plant operation.

Pre-operational measurements were conducted at CPNPP from 1981 to 1989. These pre-operational measurements were performed to: " Evaluate procedures, equipment, and techniques;" Identify potentially important pathways to be monitored afte plant operation;" Measure background levels and the variations along potentially important pathways;" Provide baseline data for statistical comparisons with future operational analytical results.6 The operational Radiological Environmental Monitoring Program is conducted to: " Verify that measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways;" Verify the effectiveness of in-plant measures used for controlling the release of radioactive materials;" Identify changes in the areas at and beyond the site boundary that may impact the principal pathways of exposure.This report documents the twenty-second year of operational measurements and is submitted in accordance with the requirements of the CPSES Offsite Dose Calculation Manual, Pan I, Administrative Control 6.9.1.3.II. Program Descriptions and Results Within a radius of twenty miles of the CPNPP site there are seventy-three (73) sample locations included in the monitoring program for the year 2012. The number of sample points and the specific locations for the sample points were determined by considering locations where the highest off-site environmental concentrations have been predicted from plant effluent source terms, site hydrology, and site meteorological conditions.

Other factors considered were applicable regulations, population distribution, and ease of access to sampling stations, availability of samples at desired locations, security and future program Integrity.

Additionally an annual land use census is conducted to identify changes in the areas surrounding the plant. If changes are identified that impact the principle pathways of exposure, appropriate changes to the radiological environmental monitoring program are implemented.

A copy of the report"Comanche Peak Nulear Power Plant Land Use Census 2012" is provided in Appendix A to this report.Table 1 -Comanche Peak Nuclear Power Plant Radiblo" &U nvirontnntal Monitrigf.n g Proam f&212 contains a brief outline of the current program. This table specifies the sample media type, the number of locations for each media type, the sector and distance identifier for each sample location, the sample frequency, the type of analysis required and the analytical frequency required.7 Table 2 -Key to Environmental SaSnfine Locations provides a reference that links the sampling point designations used in procedures and forms to the appropriate physical sample location (sector and distance) and to the correct sample type. This cross-reference enhances the ability to review data and tie the data to the correct sample points and to ensure all samples are collected and analyzed as specified.

Currently there are no milk sample locations within ten miles of the CPNPP site and there are no milk sample locations within twenty miles that will participate in the environmental program. CPNPP already samples extra broadleaf locations as required due to no milk locations within the ten-mile radius therefore, no changes to the program are necessary.

Milk sampling will be resumed if any future annual land use census determines a dairy has been established within the specified area.S Table 1 -Comanche Peak Nuclm Power Plant Radiological Environmental Mont tit 2 ogrami, M2 Number of Identification by Sector and Distance (miles) gAnalysal Locations Frequency (a) Frequency (ay-N-1.45; N-4.4; N-6.5; N-9.4; NNE-1.1; NNE-5.65;NE-1.7; NE-4.8; ENE-2.5; ENE-5.0; E-0.5; E-1.9;E-3.5; E-4.2; ESE-1.4; ESE-4.7; SE-1.3;Gamma SE-3.85; SE-4.6; SSE-1.3; SSE-4.4; SSE-4.5; A c y 0, A Expoure43 S-1.5; S-4.2; SSW-I.1; SSW4.4; SW-0.9; 0, A 0.ial tkuaWQ A Exposure SW-4.8; SW-12.3; WSW-1.0; WSW-5.35; Luminescent Dosimesry WSW-7.0; W-1.0; W-2.0; W-5.6; WNW-1.0;WNW-5.0; WNW-6.7; NW-1.0; NW-5.7; NW-9.9;NNW-1.35; NNW-4.6 Ar Grom Bet% ...Air Pautle N-9.4; E-3.5; SSE-4.5; SW-123; NW-1.0; W Gamm Isotopic Fiter Air Iodin N-1.45; SW/WSW-0.95; SISSW-1.2 Gamma IsotopicoW Surface Water 4 N-19.3; ESE-1.4; N-1.5; NE-7.4 M(b) Gamma IsCoto M Tritium 0 Gros Bete M Surface Gamma lsotopc M W r2 NN.O.1; N--.9 M(c) kxcline-131 M Trium 0C Brodllz 3N-145 W-3, MGamlma Isotopic Q Ground Wat 5 SSE-4.,;W-1;WSW4 1;N-98;1-1.45 Tittiau 0 Sediment 4 U- 9;9 NNE-1.O; NE-7A; SE-5.3 SA Gamma Isoop SA Fish 2 NNE-8.0; ENE-2.0 SA GaXmm wsow*p SA Food Ptoducts 2 ENE-O.0, E-4.2 104xlne-131c MH Bodif3 N-1.46; SW-I.0; SW-13.5 14 Gamma fstopic 14 (a) Freqnecy codes am: W-Weekltr, WkotI CQwly, QC-weuMt Composite; MH4kM y at Harvest SA-Smwu A-Annual (b) Surface water swa m from Squaw Creek are motly composites of weeldy grab sampl.

The monitoring locations were chosen according to the criteria given in the USNRC Branch Technical Position on Radiation Monitoring (Revision 1, November 1979). The area around the station was divided into 16 radial sectors of 22-1/2 degrees each, corresponding to the cardinal points of the compass. OSLs were placed in each of these sectors. The Optically Stimulated Luminescent dosimeters were placed in two rings around the station. An inner ring was located as close as possible to the site boundary and an outer ring was located at a distance of 4 to 6 miles from the station. Eleven additional OSLs were located at points of special interest, including two control locations.

For routine direct radiation measurements, two sets of the Optically Stimulated Luminescent dosimeters (OSLs) were used at each of the 43 monitoring locations.

One set of OSLs was exchanged on a quarterly basis and a second set of OSLs was exchanged on a yearly basis. Additional sets of in-transit OSLA were used as control OSLs for the quarterly and annual OSLs.From years 2001 to 2008 thermoluminescent dosimeters TLDs were processed on-site by CPNPP National Voluntary Laboratory Accreditation Program (NVLAP) certified dosimetry personnel.

Individual dosimeters were calibrated by exposure to an accurately known radiation field from a certified Cs-137 source. The year 2001 was the first year that CPNPP used the Panasonic TLD System to supply all the required direct radiation (ambient) monitoring.

In 2009 CPNPP contracted the services of Landauer Inc. to provide and process Optically Stimulated Luminescent dosimeters (OSLs.) The OSLs are used to determine the direct (ambient) radiation levels in designated monitoring locations.

Landauer Inc. is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP.)D. C. Oakley's report "National Radiation Exposure in the United States", published in 1972, calculated a background radiation dose rate equivalent of 0.22 mr/day for the area surrounding Fort Worth, Texas. This calculated value varies widely with changes in location but represents an appropriate reference value to compare with actual measured OSL doses.Using data from the pre-operational program for the two years prior to the startup of Unit 1, the quarterly TLDs averaged a calculated dose rate of 0.14 mr/day while the yearly TLDs averaged a calculated dose rate of 0.16 mr/day. The range of measured values from this same two-year period varied from a minimum of 0.11 mr/day to a maximum of 0.22 mr/day.11 Table 3 -2012 EnIm tal Direct Radiation Results contains the measured dose (mr) for each quarterly OSL from each of the 43 monitoring locations.

The corresponding quarterly calculated dose rate (mr/day) values are listed as well. The statistical average doses (mr) and dose rate (mr/day) values for each set of quarterly OSLs is also displayed.

Additionally, the table includes the total dose (mr) of all four quarters for each specific location.

The table also includes the measured dose (mr) for each annual OSL from each of the 43 monitoring locations.

The* corresponding annual calculated dose rate (mr/day) values are listed as well. The statistical annual average dose (mr) for the entire set of annual OSLA is reported along with the average dose rate (mr/day) for the entire set of annual OSLs.For the year 2012, the measured dose rates of all the quarterly OSLs ranged from a minimum of 0.158 mr/day to a maximum of 0.378 mr/day with an average dose rate of 0.297 mr/day. This resulted in an average quarterly dose of 24.5 mr and a total annual dose of 98 mr for all of the forty three monitoring stations.The measured dose rates of all the annual OSL's ranged from a minimum of 0.130 mr/day to a maximum of 0.X8 mr/day with an average dose rate of U,175 mr/day. This resulted in an average quarterly dose of 16.25 mr and an average annual dose of 65 mr for all of the forty three monitoring stations.Comparing the pre-oeational data and operational data collected through the year 2012 did not produce any anomalies.

The direct radiation dose data for 2012 was consistent with previous years of data during both the pre-operational program and the previous years of the operational program except as noted on Table 14.. Table 14- OSL Trnd Ouartey Average contains the average quarterly OSLJTD for the five most current years from each of the 43 monitoring locations.

The implementation of the Landauer OSL system, the algorithms and type of holders for the OSL's used to process the data from the OSL badge (implemented in 2009)accounts for the lower values.No abnormal quarterly results were obtained by either CPNPP or by the State of Texas, Bureau of Radiation Control.During the year 2012, there were no em mptIons to the Direct Radiation Program.12 T 3 -2112 Envhwnaw W* Radalan ats (Unit of mr dow and mr/dsy don rn)I1ST OK61.......____ QTP A ..t C A"E A!raE.

The F422 annual OSL reading was consistent with all other monrt locations.

LeISdM Air particulate and air iodine samples were collected each week from the eight monitoring locations described in Table I. Comanche Peak Nuclear Power Plant I EM far 2012, Each air ,i1 particulate sample was collected by drawing air through a 47 millimeter-diameter glass-fiber filter. Air iodine was collected by drawing air through a TEDA impregnated charcoal cartridge which was connected in series behind the air particulate filter. Shipped to an independent laboratory, air particulate filters were analyzed weekly for gross beta activity and were composited quarterly for gamma spectrometry analysis.Charcoal cartridges were analyzed weekly for lodine-131.

For the yar 2012, a total of 415 air particulate filters were collected and analyzed for gross beta activity.

The reported gross beta activity ranged from a minimum value of 1ME-02 pCl/m° to a maximum value of 1.01E.1 pCII 3.Table 4 -2012 Envial Air e Particulate Gross Bet Re contains the reported values of all samples. There were no anomalies noted in the data reported for 2012 when compared to pre-operational and previous operational datam Graph 1-2012 Environmeutal Air Sample Gross Beta eult -U M- ximumand Minimum trends the weekly high and low gross beta values to show the seasonal variation of the results as well as providing indication of consistency between the individual monitoring locations.

A total of 416 charcoal cartridges were analyzed for arbome Iodine-131.

Table 5 -2011 Environmenl Ar SAM&e ,131 U MU contains the reported values of each Iodine-131 analysis, all of which are less than the required lower limit of detection (LLD).All air particulate filters were collected and composited quarterly and then analyzed by gamma spectrometry.

The gamma isotopic data is presented in Tale 6 -2012 Environmental Air Particulate C i Gamm Isotopi Results. Typical of pre-operational and previous operational data results, the only radioactive nuclide identified in all the samples was cosmogenic Beryllium-7, a naturally occurring isotope. Several Air Particulate Composite results were positive for Potassium.-4.

However, results indicate both were below the reporting levels, A review of all the State of Texas air sample data indicated no anomalies.

However, on 6/19/12 State I Sampler had no particulate filter and no Beta analysis was determined for that period. CR 2012-006195 was written to document this event.During the year 2012 there was me txmpd to the Airbore Program. A deficiency occurred on 7/24/12. Air Sampling Station A-7 was missing a particulate filter, therefore, no Beta analysis was available for the period 7/17/12 through 7/24112. CR 2012-007374 was written to document this deficiency.

Location N- 1.5 provides samples representative of Squaw Creek reservoir surface water at a location beyond significant influence of the plant discharge.

Location ESE-1.4 provides samples representative of discharges from Squaw Creek reservoir downstream to Squaw Creek and to Lake Granbury via an installed return line. [NOTE: The installed return line to Lake Granbuwy has never been used to send water back to Lake Granbury.]

Location NE-7.4 provides samples of Lake Granbury surface water downstream of the discharge from the return line from Squaw Creek reservoir.

A control sample is obtained from the Brazos River, upstream of Lake Granbury at location N-19.3. Surface water samples from Squaw Creek reservoir locations were collected weekly and composited for monthly gamma isotopic analysis.

Samples from Lake Granb"'y locations were collected monthly and analyzed by gamma spectrometry.

All surface water samples were also composited quarterly by location for tritium analysis.For the year 2012 all surface water samples were collected as required.

Table 7- 2012 EnviAm Surace Water Tritium and Gamma IsoW R=&lt contains the reported values. Forty-eight samples were analyzed by gamma spectromery.

All results for the required radionuclides were reported as less than the required LLDs. Sixteen quarterly composited samples were analyzed for tritium. The results of the reported tritium values for Squaw Creek reservoir were in line with expected concentrations.

The tritium values ranged from a high of 1.69E*44 pCi/l to a low of 1.49E+04 pCi/l. The results from Lake Granbury were all less than the required LLDs as expected.

The tritium concentration reported in Squaw Creek is below the action level of 3,,44 pCi/A and is following the expected concentration variations based on fuel cycles, power histories and reservoir makeup due to rain and pump transfers from Lake Granbury.

2Q- a Environmental Surface Water Tritium HS indicates the current results and the short-term trend of the tritium concentration in Squaw Creek reservoir.

mtbkIl-Copiatch Peak Nuclea Power Plant Rwdwlgical Envionmen Moitoring B=m= for 2012 details the location and types of analysis required.

Samples of water from Squaw Creek reservoir were collected at the monitoring location NNW-0.1 and analyzed at detection levels required for drinking water standards even though the water is not allowed to be used as potable water. There is not a surface water drinking source within a mile of CPNPP. Monitoring location N-9.9 was used as a surface drinking water location based on the proximity of the City of Granbury intake to the Granbury potable water system. All suwace drinking water samples were collected weekly and then composed for Iodine-I 31 analysis, gamma isotopic analysis, and gross beta analysis on a monthly basis. Tritium analysis was performed on a quarterly basis.For the year 2012, all samples were analyzed for gamma emitting radionuclides.

The results are reported in Table 8 -EnviromUental Surac 2Dinking Wate Tritium. gaos WeA nd Gamm lsMtoW There were no gamma emitting radionuclides identified in any of the twenty-four composite samples. Tritium reported in Squaw Creek reservoir ranged from 1ASE+04 pCI/ to 1XE404 pCH and averaged 1.63E.04 p Tritium reported from all Lake Granbury water samples indicated less than the required LLiD as expected.

Groundwater supplies in the site area are not affected by plant effluents and are sampled only to provide confirmation that groundwater is not affected by plant discharges.

Groundwater samples were collected quarterly and analyzed for gamma isotopes and tritium at each location.For the year 2012 a total of twenty groundwater samples were collected from the five different monitoring locations.

There were no radionuclides identified in any of the samples. All required LIJs were met for each required gamma emitting radionuclide.

Tritium analysis was performed on twenty samples, all indicated less than the required LLD. Results for all the groundwater analyses ar reported in ITble 9,2I12 nvXironal Qmwif TIiman= SGaQma ls=Rki BMW. Mis results confirm that plant discharges are having no effect on groundwater in the area surrounding Comanche Peak.The 2012 samples of perched groundwater were taken quarterly in accordance with ENV-323, "TRITIUM GROUNDWATER MONITORING PROGRAM" and STA-654, GROUNDWATER PROTECTION PROGRAM. A sample from the Drainage Flow Catch Basin had a positive value of 4550 picocuries/liter) for Tritium. The 2012 sample from the Drainage Flow Catch Basin had Values ranging from 2210 to 4550 picocuries/liter for Tritium. The sample from the Water Production plant leachate pond A had a positive value ranging from <7.68E-07 picocuries/fiter to 17900 picocuries/liter.

Variations in the tritium values from the Pond A Leachate are thought to come from pockets of water trapped in between the inner and outer liner by many inches of lake sediment resting on top of the liner. These pockets of water are from basin water previously transferred to the space between the liners to test for liner repair work effectiveness.

Work is in progress to remove this sediment from the pond. As the sediment is removed, pockets of residual basin water are reintroduced into the Leachate sample. No further evaluation is necessary.

These had been previously documented in CR-2011-003303, CR 2011-009873 and CR-2011-010251.

One sample location is along the shore of Squaw Creek Reservoir, one sample location is on Squaw Creek down stream of the dam discharge and two locations are along Lake Granbury's shores. Each sample is collected on a six-month frequency and sent to the contract laboratory for analysis by gamma spectrometry.

The process of shoreline sedimentation is a complex evolution whereby potential radionuclides and stable elements may concentrate in the bottom sediment of particular bodies of water. The concentrations are effected by such things as colloidal particles combining with chelating agents and biological action of bacteria and other benthic organisms.

Monitoring of the area shorelines provides one of the first and best indicators of radlonuclide deposition.

For the year 2012 results from the gamma isotopic analysis of shoreline sediments is reported in Table 10- 2012 Environmental Sediment.Gamma JjgM* Resdft. As expected and in agreement with previous results from both the pre-operational and operational programs, naturally occurring Potassium-40 was detected in all eight samples and Beryillum-7 was detected in one sample. All required radionuclide results were reported as less than the required LLDs. During previous years, both pre-operational and operational, positive indications occasionally had been noted for Cesium-137 and during 2012 there were no positive Cesium.137 results reported.

As expected, there were no results in any sediment sample that indicated any direct influence from CPNPP discharges to the local environment.

One monitoring location is an area approximately two miles east-northeast of the site on Squaw Creek Reservoir.

The second location is on Lake Granbury approximately eight miles north-northeast of the site. Fish sampling is scheduled for the months of April and October. The collected fish are frozen and shipped to the independent laboratory where the edible portions are analyzed for gamma emitting radlo-nuclides.

For the year 2012, the results of the analysis performed on the collected fish samples are reported in Table I 1 -- 2012 Environmental Fish GMm Iotoi"c Bm1&b. Catfish and Bass samples were analyzed as indicated in the table. There were no positive results reported except for the expected Potassium-40, which is naturally occurring in all living organisms.

All required radionuclide results were reported as less than the required LLDs. As a result of the fish-sampling program, there were no anomalies noted and no indication of any influence on the surrounding environment from Comanche Peak plant discharges.

No abnormal results were reported by CPNPP or by the State of Texas. As expected, Potassium-40 was the only positive isotope found.During the year 2012 there were no eseeptions to the Fbh Program.34 Table 11 -2012 Environmental Fish Gamma Isotopic Results (Unfts of pCftk wet)DW-140 TOM C04O C*43 UThF F.U T-13 !-4 E M44 04-17-12 SQuw CrF* <9.2E-02 <6.IOE-0 <4.581i-.3

The only hndxcakit directly atrbadblfe to Comumch PeaNk Is the tridum detectled in Squaw Creek reservoir.

Gross beta trend indications concerning Squaw Creek Reservoir are generally consistent, but some seasonal differences are observable.

The general Gross Beta trend does not indicate any increase due to influence from Comanche Peak. Future data will be evaluated as it is received and changes will be addressed as necessary.

The atmospheric environment was sampled for airborne partmulate matter, radioiodine and direct radiation.

The terrestrial environment was sampled using groundwater, surface drinking water, food products and broadleaf vegetation.

The aquatic environment was sampled using surface water, fish and shoreline sediments, All other analyses of provided results were below the measurement detection limits, or were indicative of expected natural terrestrial and cosmogenic levels, except for the tritium in the water samplesof Squaw Creek reservoir.

The tridumn la Squaw Creek reservoir showed some inrase, but is expected to remain well below the reportable level.There were no values reported during the year 2012 that excesded any NRC reportable UmIt.L.

For the corrective actions associated with RAD-88, and RAD-90, refer to corrective actions CARRI20306-667 and CARRI20831-715 (Table 8) in the GEL Laboratories LLC 2012 Annual Quality Assurance Report..Corrective Action Request and Report (CARR)There are two categories of corrective action at GEL, One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002.

A formal coriective action is initiated when a nonconformance reoccurs or is so significant that permanent elimination or prevention of the problem is required.

GEL includes quality requirements in most analytical standard operating procedures to ensure that data are reported only if the quality control criteria are met or the quality control measures that did not meet the acceptance criteria are documented.

A formal corrective action is implemented according to GL-QS-EOO2 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement.

Recording and documentation is -performed following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.

Any employee.at GEL can identify and report a nonconformance and request that corrective action be taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002.

In the event that correctness or validity of the laboratory's test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of the discovery.

Quality Assurance Program for Internal and External Audits During each annual reporting period, at least one internal assessment is conducted in accordance with the pre-established schedule from Standard Operating Procedure for the Conduct of Quality Audits, GL-QS-E001.

The annual internal audit plan is reviewed for adequacy and includes the scheduled frequency and scope of quality control actions necessary to GEL's QA program. Internal audits are-conducted at least annually in accordance with a schedule approved by the Quality Systems Director.Supplier audits are contingent upon the categorization of the supplier, and may or may not be conducted prior to the use of a supplier 42 or subcontractor.

Type I suppliers and subcontractors, regardless of how they were initially qualified, are re-evaluated at least once every three years. In addition, proqatlivc ustonis audit GEL during pre-contract audits. GEL hosts several external audits each year for both our clients and other programs.

These programs include environmental monitoring, waste characterization, and radiobioassay.

43 Appendix A Comanche Peak Nuclear Power Pht Land Use Census 2012 COMANCHE PEAK NUCLEAR POWER PLANT LAND USE CENSUS 2012 The Land Use Census identified receptors within a five (5) mile radius of the plant in each of the sixteen (16) meteorological sectors. The Land Use Census was conducted July 23 -27, 2012 and includes the following items: 1. Evaluation of the 2012 Land Use Census 2. Nearest Resident by Sector, Distance, X/Q and D/Q 3. Nearest Garden by Sector, Distance and D/Q 4. Nearest Milk Animal by Sector, Distance and D/Q 5. Population by Sector and Distance 6. Environmental Sample Locations Table 7. Environmental Monitoring Locations Map- 2 Mile Radius*8. 5 Mile Sector and Road Map with Field Data*9. Environmental Monitoring Locations Map -all sample locations*These maps are vaulted along with this census. Copies of this census will not contain a copy of these maps unless specifically requested.

44 L. K: ri of ~2 ~a U U~e ~The results of the 2012 Land Use Census were reviewed for impact on the Radiological Environmental Monitoring Program (REMP). The specific areas reviewed, that could be affected by changes found in the land use census, were the sampling requirements for milk, broadleaf vegetation and food products.Reviewing the milk sampling requirements from the ODCM Table 3.12-1 requires that samples are to be obtained from milking animals in three locations within a 5 km distance having the highest potential dose. If none are available, samples are acceptable from milking animals in locations 5 to 8 kmn distance where doses are calculated to be greater than I mrem per year. A sample is also required at a control location.

There are currently no identified commercial milking animals (cow or goat) within the specified distances therefore; there are no current milk samples during the year 2012. NOTE: A Control milk location was identified at 12.3 Miles SW, Deridder Dairy, but operator did not wish to participate.

CR-2011-0013802.

If no milk samples are available, the broadleaf vegetation sampling specified in ODCM Table 3.12-1 will be performed.

Broadleaf sample requirements are such that samples of broadleaf vegetation are to be collected from each of two offsite locations of the highest predicted annual average DIQ if milk sampling is not performed at all the required locations.

Currently, broadleaf vegetation samples are collected at two indicator locations (N -1.45 and SW -1.0) and one control location (SW -13.5). These indicator locations are near the site boundary in sectors where broadleaf vegetation is available and D/Q is high. Therefore, no change to the broadleaf sampling program is required.Food product sample requirements of ODCM Table 3.12-1 requires that one sample of each principal class of food product be collected from any area that is irrigated with water in which liquid plant waste has been discharged.

Of the gardens identified in the land use census, no gardens are located in any area that irrigates with water in which liquid plant wastes are discharged.

Currently, food products are sampled from one indicator location (ENE -9.0) when in season. The indicator location for ENE-9.0 for pecans at time of harvest will be continued since it is a major source of food products sold to the public.The 2012 Land Use Census did identify one location within 5 miles with a garden of greater than 500 ft 2 producing broadleaf vegetation as outlined in CPNPP procedures and Comanche Peak Steam Electric Station Offsite Dose Calculation Manual. Condition Report 2012-007544 was written to evaluate, determine if sampling/analysis is required, and initiate sample collection at this location, based on the results of the evaluation.

The sampling is based on identified locations that would yield a calculated dose or dose commitment 20% greater than established when initial control sampling was performed.

45 Calculated values for the associated X/Q and D/Q values for each controlling receptor location and pathway are included along with the receptor distances in the data tables of this land use census. The values used to determtine potential dose due to radioactive effluent discharges are the highest calculated values based on annual average values. The annual average X/Q used for dose calculations is 3.30E-6, tritium X/Q is 4.36E-6, and the D/Q value is 3.34 E-8. All these values are conservative based on the 2012 Land Use Census data and therefore no changes are required in the dose calculation parameters as verified by the field data.* X/Q units ar Sac/cubic tnter

The number of residents per house is 2.57 and 2.74, respectively.

Note: 2011 and 2012 Land Use Census was performed with the use of maps and information provided by Somervell County/Hood County 9-1-1 addressing/

geographic information system. Changes were noted during the 2011 Land Use Census in sector population which attributed to use of 911 (Hood and Somervell counties) dispatchers maps. The most notable Distance/Sector change was 1-2 miles in sector WSW which was estimated at 349 people in 2010 and 63 people in 2011. A 9-1-1 map is vaulted under RPI-714-1.

These samples arýno required for compliance with Radiological Effluent Control 3/4.12.1, Table 3.12-1, because they are not affected by plant discharges.

2) This sample (location SW6) 19 representative of discharges from Squaw Creek Reservoir both down Squaw Creek and to Lake Granbury via the return line to Lake Granbury if used.3) Plant potable water could be supplied by surface water fromSquaw Creek Reservoir (location SW6) or ground water from onsite wells (location GW2)but is normally supplied by the Somerville County Water District from the Wheeler Branch Reservoir.

Each of these possible sources of water are sampled.4) Ground water supplies in the plant site area are not affected by plant liquid effluents as discussed in CPSES FSAR Section 2.4.13 and are therefore not required to be monitored for radioactivity to meet the requirements of the Radiological Effluent Control 3/4.12.1, Table 3.12-1.5) Broadleaf sampling will be performed at the specified locations if milk samples are unavailable from any location.6) Plant Potable Water (GW2) and Glen Rose (GW3) are supplied from surface water by the Somerville Water District from the Wheeler Branch Reservoir.

7) CPNPP Security Rifle Range (GWI) is supplied by a local Well.54 Em~ ironmenral Sxnple Loc~ations )vap -2 ieRadiu.s 55 The following Drawing specifically Reference Environmental Sample Location Map 20 Mile Radius DOI
