==SUMMARY==
OF MONITORING RESULTS 5 39 SummaryTheAnnualRadiological Environmental Operating Report presentsdataobtained through analyses of environmental samplescollectedforGrandGulfNuclear Station's (GGNS)Radiological Environmental MonitoringProgram(REMP)fortheperiod January1,2015, through December31,2015.Thisreportfulfillsthe requirementsofGGNS Technical Specification 5.6.2.To supplementtheREMP,GGNSpersonnelinstalled duplicateTLDsand collected duplicate samplesduringthereportingperiod.
Radiological Environmental Monitoring Program GGNS establishedtheREMPin1978priortothestation becoming operational(1985)toprovidedataon backgroundradiationand radioactivity normallypresentinthearea.GGNShas continued to monitor the environmentbysamplingair,water,sediment,fishandfoodproducts,aswellas measuringradiationdirectly.GGNSalso samplesmilk,if commercial milk production occurswithinfivemilesoftheplant.TheREMPincludes sampling indicatorandcontrol locationswithinan18-mileradiusoftheplant.TheREMPutilizes indicator locationsnearthesitetoshowany increasesorbuildupof radioactivitythatmight occurduetostation operationandcontrol locations fartherawayfromthesitetoindicate naturally occurring backgroundradioactivity.GGNS personnel compare indicatorresultswithcontroland preoperationalresultstoassessany impact GGNS operationmighthaveonthe surrounding environment.In2015, GGNS.personnel collected environmental samplesforradiologicalanalysis.Themonitoringresultsfor indicator locations when comparedtocontrol locations and previousstudiesshowthatGGNShasno significant effectonthelocal environment.Thereviewof2015 monitoringdata,inmanycases,showed undetectableradiationlevelsinthe environment and near backgroundlevelsinpotentialexposurepathways associatedwithGGNS.Harmful Effects or Irreversible DamageTheREMP monitoringdidnot detectanyharmful effectsorevidenceof irreversible damage inthecurrentyear.

SpecificationsTable6.12.1-2;theanalyticalresultsdidnot trigger any Radiological MonitoringProgramSpecialReports.
Radioactivity Not Attributable to GGNSOverpreviousyears,theGGNSREMP detected radioactivity attributabletoothersources.Thesesourcesincludedthe Chinese nucleartestin1980andthe accidentattheChernobyl NuclearPowerPlantin1986.In2011,theGGNSREMP detected radioactivityreleasedfrom the Fukushima Dai-ichi NuclearPowerPlantfollowingtheMarch11,2011,Tohoku earthquake.In2015,theGGNSREMP detected no radioactivity attributabletoothersources.
Comparison to Federal and State Programs 6 GGNSpersonnel compareREMPdatatofederalandstate monitoring programs.Historically, the programsusedfor comparisonincludedtheU.S.
Nuclear Regulatory Commission (NRC)Thermoluminescent Dosimeter(TLD)DirectRadiationMonitoring NetworkandtheMississippi State DepartmentofHealth(MSDH),Divisionof Radiological Health monitoring program.AlthoughtheNRCTLD NetworkProgramwas discontinuedin1998,theseresults compared favorablytothosefromtheGGNSREMP.TheMSDHandtheGGNSREMPhave similar monitoring requirements.
These programs include co-located air samplingandsharing samplemediasuchaswater, sediment,fishandfoodproducts.Both programs have obtained similarresults.The2015resultsoftheMSDH monitoring program compared favorablywiththeGGNSREMPresults.
Sample Deviations*MilkTheGGNS aDCM requires collectionofmilk samplesifthereisa commerciallyavailablesourcewithin5miles(8km)oftheplant.In2015,theREMPdidnotinclude milk sampling because no commercial milk production occurredwithin5milesofGGNS.
GGNS personnelinsteadcollected vegetation samples to monitortheingestionpathway,as specified in aDCM SpecificationsTable6.12.1-1.

==2.0 Interpretation==
and Trends of Results 2.1 Air Particulate and Radioiodine Sample ResultsGGNSdidnot detectanyplantrelated gamma emitting radionuclidesinthe quarterly air particulate composites.TheREMPhad previously detected airborne radioactivity attributabletoother sources inthispathway.
These sourcesincludethe Chinese nucleartestin1980andthe accidentatthe Chernobyl NuclearPowerPlantin1986.TheGGNSREMP detected radioactivityreleasedfromthe Fukushima Dai-ichi NuclearPowerPlantfollowingtheMarch11, 2011, Tohoku earthquake.
No radioiodine was detectedin2015.Table3.1,whichalsoincludesgrossbetaactivity, provides a comparisonofthe indicatorandcontrolmeansandranges, further emphasizingthatthe airborne pathway remains at backgroundlevels.Inthe absence of plant-related gamma radionuclides,grossbetaactivityis attributed to naturally occurring radionuclides.Similartrendsare present forcontroland indicatorlocations,which support the presence of naturally occurring radioactivity.
 
===2.2 Thermoluminescent===
Dosimetry Sample Results GGNS calculatesdoseby subtracting shield readingsfromcontroland indicator locationreadingsandreports measureddoseasnetexposure, normalizedto92days.GGNSreliesonthe comparisonofthe indicator locationstothecontrollocationasanindicationofplantimpact.
Gammaradiationdoseinthereportingperiodis comparedtocontrol location readings for previousyearsasshowninFigure2-1.
The comparisonofthe indicatorresultstothecontrol,andto previous indicator results,asseeninFigure2-1andTable3.1, indicatesthatplant operationhashadno significantimpacton ambientradiationlevelsduringthereportingperiod.
In previousyears,TLD locationsM-21(SectorJ,0.4miles),M-98(SectorH,0.5miles),andM-99 (SectorK,0.4miles)wereabove background.Thedoseratesatthesethree locationsweretheresultof Nitrogen-16 (N-16)associatedwiththeinjectionofhydrogen and subsequent N-16 production.
Hydrogeninjectionintothe feedwater system provides protection against Intergranular Stress Corrosionofplant components.
Since November2010,the hydrogeninjectionratehasbeenreducedandthedoseratesatTLD locationsM-21,M-98,andM-99havereturnedtonear background levels.23 mRlqtr 20.0 16.0 8.0 4.0A o 0o x.0 Figure 2-12015TLD Readings 2010-2014 Control Location Maximum(+2Stdev)2010-2014 Control Location Minimum (-2 Stdev)0.0+1Q15 o2Q15 63Q15 x4Q15 2.3 Water Sample Results Surface water sampleswerecollectedfromthree indicator locations(Outfall007, MRDOWN, and MRDOWN During Discharge)andonecontrollocation(MRUP)andanalyzedfor gamma emitting radionuclidesandtritium.Plantrelated gamma emitting radionuclidesandtritiumremained undetectableintheupstreamand downstreamMississippiRiverlocations,whichis consistent with preoperational and previous operationalyears.Stormwaters contributetoOutfall007andcanincludetritiumasaresultof washout and entrainmentofnormal, previously monitored gaseous effluents.Asaresult,tritiumis occasionally observed.Tritiumwas measured during February (5280+/-961pCi/L),April(950
+/-554pCi/L), October (607+/-339pCi/L),and December (449+/-280pCi/L)attheOutfall007(indicator)location.
Duplicate samplesfromOutfall007during February (5090+/-950pCi/L)andApril(1200
+/-586pCi/L)showedsimilartritiumactivity.Tritiumwasnot observedintheremainingOutfall007 samples collectedduring2015.Inadditiontothetritium samplesrequiredbytheREMP,fourspecial surface watersamplesfor gamma emitting radionuclideswerecollectedattheOutfall007location(TableA8.1).Plantrelated gamma emitting radionuclides remained undetectable inthesesamples.Basedonreviewofresultsandhistoricaldata,plant operationshadno significant impactonthis pathwayduringthereportingperiod.
24 Groundwater sampleswerecollectedfromtwo locations (indicatorandcontrol)andanalyzedfor gamma emitting radionuclidesandtritium(TablesA4.1andA4.2).Inadditiontothe samplesrequiredbytheREMP,anextrasamplefromthelocationswasanalyzedforlodine-131(TableA4.3).GGNSdidnot detectanyplantrelatedgamma emitting radionuclidesortritiumin groundwater samplesduringthereportingperiod.Basedonreviewofresultsandhistoricaldata,plant operationshadno significant impactonthis pathwayduringthereportingperiod.
2.4 Sediment Sample Results Sediment sampleswerecollectedfromtwo locations (indicatorandcontrol)andanalyzedfor gamma emitting radionuclides.GGNSdidnot detectanyplantrelatedgammaemitting radionuclidesortritiumin sediment samplesduringthereporting period.Basedonreviewofresultsandhistoricaldata,plant operationshadno significant impactonthis pathwayduringthereportingperiod.
2.5 Milk Sample Results Milk sampleswerenotcollectedwithinfivemilesofthesiteinthereportingperioddueto the absenceofmilkinganimals.SincetherearenodairieswithinfivemilesofGGNS,andbasedon non-detectableradioiodineand gamma radionuclidesinairand vegetationsamples,plant operationshadno impactonthis pathwayduringthereportingperiod.2.6Fish Sample Results Fish sampleswerecollectedfromtwo locations (indicatorandcontrol)andanalyzedforgammaemitting radionuclides.GGNSdidnot detectanyplantrelated gamma emitting radionuclidesinfish samples(edibleportions)duringthereportingperiod,ashasbeenthecasein preoperationalandprevious operationalyears.Theseresultsindicatethat this pathwayhasnotbeen affectedbyplant operations.2.7Food Product (Vegetation)
Sample ResultsFoodproduct sampleswerecollectedfromtwo locations (indicatorandcontrol)andanalyzedforlodine-131and gamma emitting radionuclides.GGNSdidnot detect anyplantrelatedlodine-131or gamma emitting radionuclides in vegetation samples duringthereportingperiod.Theseresultsindicatethatthis pathwayhasnotbeen affected by plant operations.2.8LandUse Census ResultsResultsfromthemostrecentLandUse Census performedin2014 areincludedinthisreport.MethodsutilizedtoperformtheLandUseCensusinclude:visualsurveys,doortodoorsurveys, telephoneinterviews,GlobalPositioningSystem(GPS),AerialPhotography,and consultationwiththelocal county agent concerning dairy production in Claiborne County.Duringthesurveythefollowing informationwasobtained:
1)nearestlocationof occupied and unoccupied residences 25 2)nearest location of dairy production 3)nearest location of gardens Changes from the previousLandUse Census were evaluated in accordance with GGNS surveillance"Land Use Census",06-EN-SOOO-O-0002.The differences were comparedtothe locations and assumptionsusedin calculations for compliance with the ODCM Limiting Condition for Operation 6.11.6 and 6.12.2.The locations and assumptions currently used in ODCM were determined more conservative than any of the changes.Determinationsfromthe most recentLandUse Census results are:*Because of downwind location and/or distancefromthesite,inno casewillthe occupancyofan existing unoccupied residence cause any existing ODCM critical receptor calculation resultstobeless conservative.*No additional sampling locations are requiredasthe onsite vegetation sampling location (SectorJ,0.4 miles)is more conservative than changes identifiedinthelanduse census.*Cattle are raised forhumanconsumption (most notably in SectorsF,H,J,and K).GGNS uses the Grass/Cow/Meat pathway.*The milk pathway does not needtobe activated because no commercial dairy production is occurring within 5 miles, as referenced by ODCM Table 6.12.1-1.*SectorsM,N,P,andQare remote areasinwhichthe primaryuseis hunting.Areas were surveyed by vehicle, aerial photographs, and interviews.
*Gardens, regardlessofsize, were includedinthe census data Although not procedurally required,itis recommended thatthenext ODCM revision include an update to Table 2.2-3 to reflect the latestLandUse Census results.26 Table 2.1 2014 Land Use Census Parameter Sector A*Sector B Sector C*Sector 0*I.Nearest Occupieda.Distance(mile) 1.76 1.51 0.70 2.60 Residence b.Degreesfromtruenorth 351.6 23.7 42.3 60.8 II.Nearest Unoccupieda.Distance(mile) 0.94 0.83 None None Residence (closerb.Degreesfromtruenorth 8.0 15.1 than occupied residence)

==SUMMARY==
Routine quality control (QC)testing was performed for dosimeters issuedbythe Environmental Dosimetry Company (EDC).Duringthis annualperiod,100
%(72/72)ofthe individual dosimeters, evaluated againsttheEDC internal performance acceptance criteria (high-energy photonsonly),metthe criterion for accuracyand100%(72/72)metthe criterion for precision (Table1).In addition, 100%(12/12)ofthe dosimeter sets evaluated against the internal tolerancelimitsmetEDC acceptance criteria(Table2)and 100%(6/6)of independent testing passed the performance criteria (Table 3).Trending graphs, which evaluate performance statistic for high-energy photon irradiations and co-located stationsaregivenin Appendix A.One internal assessment was performedin2015.Therewereno findings.-iv-I.INTRODUCTIONTheTLD systemsatthe Environmental Dosimetry Company(EDC)are calibrated andoperatedto ensure consistent andaccurateevaluationofTLDs.The qualityofthe dosimetricresultsreportedtoEDCclientsis ensured by in-house performance testing and independent performancetestingbyEDC clients,andbothinternalandclient directed program assessments.
The purposeofthe dosimetry quality assuranceprogramistoprovide performance documentationoftheroutine processingofEDC dosimeters.
Performance testingprovidesa statistical measure ofthebiasandprecisionof dosimetry processing againstareliablestandard,whichinturnpointsoutany trends or performancechanges.Two programsareused:A.QC Program Dosimetry qualitycontroltestsare performedonEDC Panasonic 814 Environmental dosimeters.
Thesetestsinclude:
(1)the in-housetestingprogram coordinatedbytheEDCQA Officer and (2)independenttestperformbyEDC clients.In-housetestare performedusingsixpairsof814 dosimeters,apairisreportedasanindividualresultandsixpairsarereportedasthemeanresult.Resultsofthesetestsare describedinthisreport.Excludedfromthisreportare instrumentation checks.Although instrumentation checks represent an important aspectofthe quality assuranceprogram,theyare not included as process checksinthisreport.
Instrumentation checks represent between 5-10%oftheTLDs processed.
B.QA ProgramAninternal assessment of dosimetry activities is conducted annuallybythe Quality Assurance Officer (Reference 1).Thepurposeofthe assessmentisto review procedures, results, materials or components to identify opportunities to improve or enhance processes and/or services.II.PERFORMANCE EVALUATION CRITERIA A.AcceptanceCriteriaforInternal Evaluations1.BiasForeach dosimetertested,the measureofbiasisthe percent deviation ofthereportedresultrelativetothe delivered exposure.Thepercent deviationrelativetothe delivered exposure is calculatedasfollows:
where: H;=the corresponding reported exposureforthe l" dosimeter(i.e.,thereported exposure)Hi=the exposure deliveredtothe l" irradiated dosimeter(i.e.,the delivered exposure)1of6 2.MeanBiasForeach groupoftest dosimeters,themeanbiasisthe average percent deviationofthereportedresultrelativetothe deliveredexposure.The mean percent deviationrelativetothedelivered exposure is calculated as follows: where: H;=the corresponding reported exposurefortheith dosimeter(i.e.,thereported exposure)Hi=the exposuredeliveredtothe l" irradiated test dosimeter(i.e.,the delivered exposure)n=the number of dosimetersinthetestgroup 3.PrecisionFora groupoftest dosimeters irradiatedtoagiven exposure, the measure ofprecisionisthe percentdeviationof individualresultsrelativetothemeanreportedexposure.Atleasttwovaluesarerequiredforthe determinationofprecision.The measureofprecisionfortheith dosimeter is: where: H;=thereported exposurefortheith dosimeter(i.e.,the reported exposure)R=themeanreported exposure;i.e., R=

==SUMMARY==
OF MONITORING RESULTS 5 39 SummaryTheAnnualRadiological Environmental Operating Report presentsdataobtained through analyses of environmental samplescollectedforGrandGulfNuclear Station's (GGNS)Radiological Environmental MonitoringProgram(REMP)fortheperiod January1,2015, through December31,2015.Thisreportfulfillsthe requirementsofGGNS Technical Specification 5.6.2.To supplementtheREMP,GGNSpersonnelinstalled duplicateTLDsand collected duplicate samplesduringthereportingperiod.
Radiological Environmental Monitoring Program GGNS establishedtheREMPin1978priortothestation becoming operational(1985)toprovidedataon backgroundradiationand radioactivity normallypresentinthearea.GGNShas continued to monitor the environmentbysamplingair,water,sediment,fishandfoodproducts,aswellas measuringradiationdirectly.GGNSalso samplesmilk,if commercial milk production occurswithinfivemilesoftheplant.TheREMPincludes sampling indicatorandcontrol locationswithinan18-mileradiusoftheplant.TheREMPutilizes indicator locationsnearthesitetoshowany increasesorbuildupof radioactivitythatmight occurduetostation operationandcontrol locations fartherawayfromthesitetoindicate naturally occurring backgroundradioactivity.GGNS personnel compare indicatorresultswithcontroland preoperationalresultstoassessany impact GGNS operationmighthaveonthe surrounding environment.In2015, GGNS.personnel collected environmental samplesforradiologicalanalysis.Themonitoringresultsfor indicator locations when comparedtocontrol locations and previousstudiesshowthatGGNShasno significant effectonthelocal environment.Thereviewof2015 monitoringdata,inmanycases,showed undetectableradiationlevelsinthe environment and near backgroundlevelsinpotentialexposurepathways associatedwithGGNS.Harmful Effects or Irreversible DamageTheREMP monitoringdidnot detectanyharmful effectsorevidenceof irreversible damage inthecurrentyear.
Reporting LevelsWhenaveragedoverany calendarquarter,no environmentalsamplesequaledorexceededreportinglevelsfor radioactivityasoutlinedin Offsite Dose CalculationManual(ODCM)
SpecificationsTable6.12.1-2;theanalyticalresultsdidnot trigger any Radiological MonitoringProgramSpecialReports.
Radioactivity Not Attributable to GGNSOverpreviousyears,theGGNSREMP detected radioactivity attributabletoothersources.Thesesourcesincludedthe Chinese nucleartestin1980andthe accidentattheChernobyl NuclearPowerPlantin1986.In2011,theGGNSREMP detected radioactivityreleasedfrom the Fukushima Dai-ichi NuclearPowerPlantfollowingtheMarch11,2011,Tohoku earthquake.In2015,theGGNSREMP detected no radioactivity attributabletoothersources.
Comparison to Federal and State Programs 6 GGNSpersonnel compareREMPdatatofederalandstate monitoring programs.Historically, the programsusedfor comparisonincludedtheU.S.
Nuclear Regulatory Commission (NRC)Thermoluminescent Dosimeter(TLD)DirectRadiationMonitoring NetworkandtheMississippi State DepartmentofHealth(MSDH),Divisionof Radiological Health monitoring program.AlthoughtheNRCTLD NetworkProgramwas discontinuedin1998,theseresults compared favorablytothosefromtheGGNSREMP.TheMSDHandtheGGNSREMPhave similar monitoring requirements.
These programs include co-located air samplingandsharing samplemediasuchaswater, sediment,fishandfoodproducts.Both programs have obtained similarresults.The2015resultsoftheMSDH monitoring program compared favorablywiththeGGNSREMPresults.
Sample Deviations*MilkTheGGNS aDCM requires collectionofmilk samplesifthereisa commerciallyavailablesourcewithin5miles(8km)oftheplant.In2015,theREMPdidnotinclude milk sampling because no commercial milk production occurredwithin5milesofGGNS.
GGNS personnelinsteadcollected vegetation samples to monitortheingestionpathway,as specified in aDCM SpecificationsTable6.12.1-1.
*Required Lower Limit of Detection (LLD)ValuesAnalyticallowerlimitof detection (LLD)valuesrequiredbythe aDCM specificationsachievedin2015werewithinthelimitsforallsamples.
*Thermoluminescent DosimetersTherewereno deviationsin2015.*Air SamplesThefollowingair sample locationshadreducedruntimesdueto weather-related power outages or mechanical problems.As described in aDCM SpecificationTable6.12.1-1, footnote (a), deviationsfromtherequired sampling schedule are permitteddueto malfunction of sampling equipmentandother legitimate reasons.7 Table1.1Air Sampling Deviationsin2014RunTime Out-of-ServiceSampleLocationDateInDateOut(Hours)(Hours)

==2.0 Interpretation==
and Trends of Results 2.1 Air Particulate and Radioiodine Sample ResultsGGNSdidnot detectanyplantrelated gamma emitting radionuclidesinthe quarterly air particulate composites.TheREMPhad previously detected airborne radioactivity attributabletoother sources inthispathway.
These sourcesincludethe Chinese nucleartestin1980andthe accidentatthe Chernobyl NuclearPowerPlantin1986.TheGGNSREMP detected radioactivityreleasedfromthe Fukushima Dai-ichi NuclearPowerPlantfollowingtheMarch11, 2011, Tohoku earthquake.
No radioiodine was detectedin2015.Table3.1,whichalsoincludesgrossbetaactivity, provides a comparisonofthe indicatorandcontrolmeansandranges, further emphasizingthatthe airborne pathway remains at backgroundlevels.Inthe absence of plant-related gamma radionuclides,grossbetaactivityis attributed to naturally occurring radionuclides.Similartrendsare present forcontroland indicatorlocations,which support the presence of naturally occurring radioactivity.

The comparisonofthe indicatorresultstothecontrol,andto previous indicator results,asseeninFigure2-1andTable3.1, indicatesthatplant operationhashadno significantimpacton ambientradiationlevelsduringthereportingperiod.
In previousyears,TLD locationsM-21(SectorJ,0.4miles),M-98(SectorH,0.5miles),andM-99 (SectorK,0.4miles)wereabove background.Thedoseratesatthesethree locationsweretheresultof Nitrogen-16 (N-16)associatedwiththeinjectionofhydrogen and subsequent N-16 production.
Hydrogeninjectionintothe feedwater system provides protection against Intergranular Stress Corrosionofplant components.
Since November2010,the hydrogeninjectionratehasbeenreducedandthedoseratesatTLD locationsM-21,M-98,andM-99havereturnedtonear background levels.23 mRlqtr 20.0 16.0 8.0 4.0A o 0o x.0 Figure 2-12015TLD Readings 2010-2014 Control Location Maximum(+2Stdev)2010-2014 Control Location Minimum (-2 Stdev)0.0+1Q15 o2Q15 63Q15 x4Q15 2.3 Water Sample Results Surface water sampleswerecollectedfromthree indicator locations(Outfall007, MRDOWN, and MRDOWN During Discharge)andonecontrollocation(MRUP)andanalyzedfor gamma emitting radionuclidesandtritium.Plantrelated gamma emitting radionuclidesandtritiumremained undetectableintheupstreamand downstreamMississippiRiverlocations,whichis consistent with preoperational and previous operationalyears.Stormwaters contributetoOutfall007andcanincludetritiumasaresultof washout and entrainmentofnormal, previously monitored gaseous effluents.Asaresult,tritiumis occasionally observed.Tritiumwas measured during February (5280+/-961pCi/L),April(950
+/-554pCi/L), October (607+/-339pCi/L),and December (449+/-280pCi/L)attheOutfall007(indicator)location.
Duplicate samplesfromOutfall007during February (5090+/-950pCi/L)andApril(1200
+/-586pCi/L)showedsimilartritiumactivity.Tritiumwasnot observedintheremainingOutfall007 samples collectedduring2015.Inadditiontothetritium samplesrequiredbytheREMP,fourspecial surface watersamplesfor gamma emitting radionuclideswerecollectedattheOutfall007location(TableA8.1).Plantrelated gamma emitting radionuclides remained undetectable inthesesamples.Basedonreviewofresultsandhistoricaldata,plant operationshadno significant impactonthis pathwayduringthereportingperiod.
24 Groundwater sampleswerecollectedfromtwo locations (indicatorandcontrol)andanalyzedfor gamma emitting radionuclidesandtritium(TablesA4.1andA4.2).Inadditiontothe samplesrequiredbytheREMP,anextrasamplefromthelocationswasanalyzedforlodine-131(TableA4.3).GGNSdidnot detectanyplantrelatedgamma emitting radionuclidesortritiumin groundwater samplesduringthereportingperiod.Basedonreviewofresultsandhistoricaldata,plant operationshadno significant impactonthis pathwayduringthereportingperiod.

1)nearestlocationof occupied and unoccupied residences 25 2)nearest location of dairy production 3)nearest location of gardens Changes from the previousLandUse Census were evaluated in accordance with GGNS surveillance"Land Use Census",06-EN-SOOO-O-0002.The differences were comparedtothe locations and assumptionsusedin calculations for compliance with the ODCM Limiting Condition for Operation 6.11.6 and 6.12.2.The locations and assumptions currently used in ODCM were determined more conservative than any of the changes.Determinationsfromthe most recentLandUse Census results are:*Because of downwind location and/or distancefromthesite,inno casewillthe occupancyofan existing unoccupied residence cause any existing ODCM critical receptor calculation resultstobeless conservative.*No additional sampling locations are requiredasthe onsite vegetation sampling location (SectorJ,0.4 miles)is more conservative than changes identifiedinthelanduse census.*Cattle are raised forhumanconsumption (most notably in SectorsF,H,J,and K).GGNS uses the Grass/Cow/Meat pathway.*The milk pathway does not needtobe activated because no commercial dairy production is occurring within 5 miles, as referenced by ODCM Table 6.12.1-1.*SectorsM,N,P,andQare remote areasinwhichthe primaryuseis hunting.Areas were surveyed by vehicle, aerial photographs, and interviews.
*Gardens, regardlessofsize, were includedinthe census data Although not procedurally required,itis recommended thatthenext ODCM revision include an update to Table 2.2-3 to reflect the latestLandUse Census results.26 Table 2.1 2014 Land Use Census Parameter Sector A*Sector B Sector C*Sector 0*I.Nearest Occupieda.Distance(mile) 1.76 1.51 0.70 2.60 Residence b.Degreesfromtruenorth 351.6 23.7 42.3 60.8 II.Nearest Unoccupieda.Distance(mile) 0.94 0.83 None None Residence (closerb.Degreesfromtruenorth 8.0 15.1 than occupied residence)

==SUMMARY==
Routine quality control (QC)testing was performed for dosimeters issuedbythe Environmental Dosimetry Company (EDC).Duringthis annualperiod,100
%(72/72)ofthe individual dosimeters, evaluated againsttheEDC internal performance acceptance criteria (high-energy photonsonly),metthe criterion for accuracyand100%(72/72)metthe criterion for precision (Table1).In addition, 100%(12/12)ofthe dosimeter sets evaluated against the internal tolerancelimitsmetEDC acceptance criteria(Table2)and 100%(6/6)of independent testing passed the performance criteria (Table 3).Trending graphs, which evaluate performance statistic for high-energy photon irradiations and co-located stationsaregivenin Appendix A.One internal assessment was performedin2015.Therewereno findings.-iv-I.INTRODUCTIONTheTLD systemsatthe Environmental Dosimetry Company(EDC)are calibrated andoperatedto ensure consistent andaccurateevaluationofTLDs.The qualityofthe dosimetricresultsreportedtoEDCclientsis ensured by in-house performance testing and independent performancetestingbyEDC clients,andbothinternalandclient directed program assessments.
The purposeofthe dosimetry quality assuranceprogramistoprovide performance documentationoftheroutine processingofEDC dosimeters.
Performance testingprovidesa statistical measure ofthebiasandprecisionof dosimetry processing againstareliablestandard,whichinturnpointsoutany trends or performancechanges.Two programsareused:A.QC Program Dosimetry qualitycontroltestsare performedonEDC Panasonic 814 Environmental dosimeters.
Thesetestsinclude:
(1)the in-housetestingprogram coordinatedbytheEDCQA Officer and (2)independenttestperformbyEDC clients.In-housetestare performedusingsixpairsof814 dosimeters,apairisreportedasanindividualresultandsixpairsarereportedasthemeanresult.Resultsofthesetestsare describedinthisreport.Excludedfromthisreportare instrumentation checks.Although instrumentation checks represent an important aspectofthe quality assuranceprogram,theyare not included as process checksinthisreport.
Instrumentation checks represent between 5-10%oftheTLDs processed.
B.QA ProgramAninternal assessment of dosimetry activities is conducted annuallybythe Quality Assurance Officer (Reference 1).Thepurposeofthe assessmentisto review procedures, results, materials or components to identify opportunities to improve or enhance processes and/or services.II.PERFORMANCE EVALUATION CRITERIA A.AcceptanceCriteriaforInternal Evaluations1.BiasForeach dosimetertested,the measureofbiasisthe percent deviation ofthereportedresultrelativetothe delivered exposure.Thepercent deviationrelativetothe delivered exposure is calculatedasfollows:
where: H;=the corresponding reported exposureforthe l" dosimeter(i.e.,thereported exposure)Hi=the exposure deliveredtothe l" irradiated dosimeter(i.e.,the delivered exposure)1of6 2.MeanBiasForeach groupoftest dosimeters,themeanbiasisthe average percent deviationofthereportedresultrelativetothe deliveredexposure.The mean percent deviationrelativetothedelivered exposure is calculated as follows: where: H;=the corresponding reported exposurefortheith dosimeter(i.e.,thereported exposure)Hi=the exposuredeliveredtothe l" irradiated test dosimeter(i.e.,the delivered exposure)n=the number of dosimetersinthetestgroup 3.PrecisionFora groupoftest dosimeters irradiatedtoagiven exposure, the measure ofprecisionisthe percentdeviationof individualresultsrelativetothemeanreportedexposure.Atleasttwovaluesarerequiredforthe determinationofprecision.The measureofprecisionfortheith dosimeter is: where: H;=thereported exposurefortheith dosimeter(i.e.,the reported exposure)R=themeanreported exposure;i.e., R=
n=the number of dosimetersinthetest group 4.EDCInternal Tolerance Limits All evaluationcriteriaaretakenfromthe"EDCQualitySystemManual," (Reference 2).Thesecriteriaareonlyappliedto individual test dosimetersirradiatedwith high-energy photons (Cs-137)andareas follows for Panasonic Environmental dosimeters:
