FOREWORDOnAugust22,1969,'iagaraMohawkPowerCorporation(NiagaraMohawk)receiveditsprovisionaloperatinglicense(DPRNo.17)fromtheUnitedStatesAtomicEnergyCommission(Commission)tooperateNineMilePointNuclearStationUnit1at1,538MWt(500MWe).OnApril14,1971thepowerratingforthislicensewasincreasedbytheCommissionto1,850MWt(610MWe).PursuanttoSectionAofrevisedAppendixDto10CFRPart50,thisenvironmentalreportaccompaniesNiagraraMohawk'sapplica-tiontoconverttheprovisionaloperatinglicenseforNineMilePointUnit1toafull-termlicense.Thecontentsofthisreportgenerallyconformtothe<<DraftGuidetothePreparationofEnvironmentalReportsforNuclearPowerPlants"issuedbytheCommissionFebruary1971,asamended,includingthesubstanceoftheinformationrequiredbytheMay1972<<GuidetothePreparationofBenefit-CostAnalyses<<,ThoseotherpointsatwhichthisreportdeviatesfromtheaboveguidelinesarenotedinthisForeword.SinceUnit1isanoperatingfacility,thereportdescribingitsenvironmentalimpactmustnecessarilydifferinbothscopeandcontentfromthatappropriatetotheconstructionpermitstage.Theprimaryconcernattheoperatinglicensestageiswhethertherehasbeenanyadverseimpacttodatefromtheoperationofthefacilityorwhetheranyadverseimpactcanbepredictedfromitscontinuedoperation.Considerationofalternativesmustofnecessitybelimitedtothosewhichhaveabearingoneitherofthesetwoimpacts.ThebenefitofthepossibleadoptionofanyofthesealternativesmustbebalancedagainstthecosttoNiagaraMohawkoftheirimplementationandtothepublicfrom.theinterruptionofservice.Afurtherdifferenceisthatthisreportfocusessolelyontheinteractionofanoperatingfacilityuponitsenvironment.Accordingly,analysisofthefacilitysimpactontheenvironmentbeginswithstart-upin1969untilthepresent.Referencestopreconstructionsiteenvironmentaremadeonlyforcomparisontothesiteatpresent.Thediscussionofconstructioneffectsislimitedtocontemplatedmodificationsofthefacility.ThisreportdescribesindetailthestepstakenbyNiagaraMohawkinthedesignandoperationofthestationtoavoidadverseenvironmentaleffects.AlsodiscussedaretheeffortsbyNiagaraMohawktoenhancethesiteandthenearbyenvironment.Someoftheinterpretationschoseninpreparingthisdocument,whicharesupportedbythelegislativehistoryoftheNationalEnvironmentalPolicyAct,(83Stat.852,January1,1970)aswell
