1. ItisevidentthatLeviathanproponents(industryandgovernment)havededicatedanimpressiveamountoftime,effort,andfinancialresourcesinplanninganddevelopmentoftheprojecttodate.Therevieweddocumentspresentathoroughbackgroundofthebaselineregionalenvironment,abasicdescriptionoftheproject,andreasonableassessmentofsomeoftheexpectedconstructionandoperationalimpacts.
2. ItisnotedthattheLeviathandevelopmentisconsiderablyadvancedat
present,withseveralwellshavingbeendrilledandcompleted.ThusthecommentsbelowmayhavebeenmoreusefultoprojectplannersandtheGovernmentofIsraelifprovidedearlierintheprocess.Nevertheless,thecommentsandconcernsoutlinedinthisreportremainrelevantforallaspectsoftheproject.Evenatthisstageofprojectdevelopment,itishopedthatthisreportmayhelpimprovetheenvironmentalsafetyoftheproject.
3. Thedocumentsreviewedareinsufficientuponwhichtoconcludethatthe
Leviathanprojectmeetsitssafetydeclarationsandobjectivesandbestindustrypractice.Significantly,documentsunderstatetherisksandimpactsoftheLeviathanprojectfromapotentialcatastrophicfailureofanyoftheseveralsystems-criticalprojectcomponents,andoverstateresponsecapabilities.Thedocumentsfailtoaccountforthemanywaysinwhichacomplexsystemsuchasadeepwatergasprojectcanfail,causingalowprobability/highconsequenceeventsuchasamajorgas/condensatewellblowoutorpipelinerelease.Inthepost-DeepwaterHorizonunderstandingofdeepwaterdrillingrisks,thisisunacceptable.Whileimpactsfromconstructionandnormaloperationoftheprojectmaybemoderateaspredicted,impactsofmajorfailurescouldbecatastrophic.Thesecatastrophicriskshavenotbeenadequatelyassessed.
4. TheLeviathandocumentsreviewedarepoorlyintegrated,redundant,often
inconsistent,containsignificanterrors(e.g.unitsofmeasurement),containsignificantgapsinessentialinformation,andoftenmakevagueandgeneralassertionslackingdetail.Thispoororganizationofdocumentsmakesit

difficultforthepublictoassimilateprojectinformationandreasonablyevaluateenvironmentalimpactsandrisksoftheproject.
5. ThecurrentstatusofLeviathandevelopmentandpermittingremainsunclear
totheauthor.Theprojectschedulereportedinthe2016DrillingEIAstatesthatoffshorewelldrillingandcompletionwouldbeunderwayatthistime.Yet,thereismuchdetailonthisandotheraspectsoftheprojectthatwereunavailabletotheauthor,includinganyApplicationsforPermitstoDrill(APD).Thispresentedasignificanthandicaptoacomprehensivereviewoftheproject.

Condensateisalight,volatile,andacutelytoxicpetroleumhydrocarbonmixturethatbehavesverydifferentlythanheaviercrudeoilwhenreleasedintothemarineenvironment.Condensatereleasesgenerallydonotformdefinablesurfaceslicks(asdocrudeoils),andthuscondensatespillsarenotamenabletotraditionalspillresponsemethodologies.Whilenotaspersistentascrudeoilwhenreleasedintotheenvironment,condensatescanpersistforwellover6monthsoncereleased.Inaddition,weatheredcondensateisknowntobeevenmoreacutelytoxicthanfreshcondensate,downtoconcentrationsaslowas0.04ppm(40ppb).

8. FortheDrillingphase,MEDSLIKmodeledawellheadcondensatereleaseof
857m3(5,827bbls)/dayx30days(thisdatawasredacted,butretrievable),foratotalreleaseof25,110m3,orabout175,000barrels(bbls).Giventhehistoryofdeepwaterpetroleumblowouts,thisisclearlynotaWorstCaseDischarge.Theprojectshouldmodelablowoutatthisratecontinuingforatleasttwicethislengthoftime(60days),foranapproximatecondensatereleasevolumeof350,000bbls.
9. Bycomparison,thefailedMacondooil/gaswelldrilledbytheDeepwater
Horizonin2010intheU.S.GulfofMexico,atcomparabledepthandpressuretoLeviathan,releasedanaverageof62,000bbls/dayofoilover87days,foratotaloilreleaseof4.9millionbbls(oilequivalent).Andthe2009Montaraoil/gasplatformblowoutoffnorthwestAustralia(inonly76mwaterdepth)continuedfor74days.Accordingly,the30-daywellblowoutperiodmodeledforLeviathanisinsufficient,andshouldbeincreasedtoatleast60days.
10. FortheProduction(seabedpipeline)phase,themodeledWorstCase
Dischargewasapprox.1,220bbls–1,320(194m3)bblscondensate,based

onthereleaseoftotalpipelineinventory,plus5minutesresponsetimetoshut-inthepipeline.ThisrepresentsanunderestimateofpotentialWorstCaseDischargevolume,andshouldberevisedupward.Thisunderestimatederivesfromtheassumptionthatapipelinefailurewillbeimmediatelydetectedandshut-inwithproperfunctioningoftheSurfaceControlledSubSurfaceValve(SCSSV)systemfromtheLeviathanProductionPlatform.However,thereisnodiscussionofacontingencyforthefailureinthissurface-controlledsystem(e.g.severedumbilicalconnection,fire/explosionontheLPP,etc.),whichcouldleadtoamuchlargerreleaseofgasandcondensatefromseabedpipelines.
11. ForthenearshoreLeviathanProductionPlatform(LPP),theOSCARmodel
assumesareleaseofonly1,000bblscondensate,whileOSCARalsomodelsaverysmallcondensaterelease(fromadroppedobject),ofonly15.9bblsofcondensateand75tonsofgas.MEDSLIKalsomodeleda100,000bblscondensatereleasefromaFloatingStorageandOffloading(FSO)tanker/facility(NOP37/HGuidelines),whichwasnotselectedforthefinalLeviathandesign.Atminimum,areleaseoftheentirestoragecapacityofapprox.5,000bblsofcondensatefromtheLPPshouldbemodeled.Bothmodelsassumeapprox.40%-50%evaporationofcondensate,withtheremainingbalancedispersinginthemarineenvironmentand/orbeachingonshorelines.BothmodelspredictsubstantialshorelinecontaminationfromaWorstCaseDischargecondensatereleaseattheLPP.
12. Surprisingly,theLeviathandocumentsdonotdiscussindetailthepotential

13. Regardingecologicalimpactsofcondensatereleases,thedocumentsassert
that:“NoHighriskimpactswereidentifiedintheevaluationfromroutineactivitiesoraccidentalevents.”Thisisnotsupportable.Ifasmodeled,175,000bblsofcondensateisreleasedfromaLeviathandeepwaterwellfailure,spreadsover395,000km2ofcoastalocean,resultsinwaterhydrocarbonconcentrationsinexcessof300ppm,persistsformonths,andcontaminates388kmofshorelinesfromEgypttoSyriawithover88,000barrelsoftoxicweatheredcondensate;thenclearlytheecologicalimpactswouldbe“high”,not“moderate”aspredictedbytheEIAs.IfaWorstCaseDischargeoftwicethismuchorlargeroccurs,thenimpactswouldbecorrespondinglygreater.

impactsfromamajoroffshoregas/condensaterelease. Mitigation/SpillPrevention
15. Mitigation/spillpreventionispoorlydevelopedinthedocuments.Asthisisthemostcriticalaspectofenvironmentalriskreduction,thisneedsconsiderablymoretechnicaldetail.Forinstance,thedocumentsdonotpresentaclearplanforpreventingwellblowoutsorseabedpipelinefailure,robustwelldesignandcontrol,pipelinedesign,pipelineIntegrityManagement(IM)program,pipelineLeakDetection,personneltraining,thirdpartyservices,managementofchange,near-casualtyreportingandinvestigation,riskassessment,subcontractormanagement,andequipmentmaintenanceandsurveillance.AlthoughseveraldeepwatergaswellshavebeensuccessfullydrilledoffIsraelinrecentyearswithnoreportedmajorhydrocarbonrelease,anyofthenextwellsdrilledcouldfailcatastrophically.Priortothe2010DeepwaterHorizonoil/gasblowoutintheU.S.GulfofMexico,hundredsofdeepwaterwellshadbeendrilled,mostwithnowell-controlincident.TheLeviathandocumentsprojectatroublingsenseofcomplacencyaboutthisveryrealrisk.

17. Aconsiderableamountofsystems-criticalinformation(asreferencedabove)
issimplyredactedfromdocuments.Thisishighlyunusual,andforaprojectwithsuchpotentialconsequenceandpublicinterest,isunacceptable.
18. The2011Leviathan2blowoutismentionedbrieflyintheDrillingEIA,but
insufficientdetailisprovided.Asaresultofthislossofwellcontrolincident,thedrillrigdisconnectedfromthewell,andformationwaters/brineflowedfromthefailedwellfromMay2011–Sept.2012(16months)beforebeingplugged.Thisisanunacceptableresponsetoawellcontrolincident,and

24. PipelineIntegrityManagementandLeakDetectionSystemsareinadequately

25. TheGovernmentofIsraelshouldcommissionacomprehensivethird-party

26. ThefrequencyofunderwaterRemotelyOperatedVehicle(ROV)surveyson
seabedinfrastructureshouldbeincreasedfromannually,ascurrentlyplanned,toatleastmonthly.
27. ItisnotclearthatfireandexplosionriskontheLeviathanProduction

Platformvs.FPSOorFLNG
28. TheoveralldesignselectedforLeviathaneliminatedoptionsforoffshoreFloatingProduction,Storage,andOffloading(FPSO),orFloatingLiquefiedNaturalGas(FLNG),inuseelsewhereintheworld,withoutadequateconsideration.AnFLNGfacility125kmoffshore,shippingLNGviashuttletankers,wouldeliminatemostnearshorerisksandimpactsinherentinthecurrentprojectdesign,whichincorporateshundredsofkmofseabedpipelinesandaplatform10kmoffshore.AndanFPSO,also125kmoffshore,evenwithseabedpipelinestransportinggastoshore,wouldalsoeliminatethesubstantialrisksposedbythenearshoreplatform.Inevaluatingalldesignoptionsfortheproject(includinganentirelyoffshoreoption),thedocumentsclaim:“Therewerenosignificantenvironmentaldifferentiatorsorshowstoppersidentifiedacrossalloftheviableoptions.”Thisiscategoricallyincorrect,astheoffshoreFPSOorFLNGoptionwouldsignificantlyreduceoreliminaterisksandimpactstothecontinentalshelfenvironmentandcoastalpublicsafety.Accordingly,thecurrentprojectshouldbesuspendedandtheFLNGorFPSOoptionreconsideredandadopted.
29. RegardingtherelativeenvironmentalbenefitofFLNGvs.onshore/near
shoreprocessing(ascurrentlyplannedinLeviathan),RoyalDutchShellstatedwithregardtoitsPreludeFLNGprojectoffthecoastofAustralia: “FLNGtechnologyofferscountriesamoreenvironmentally-sensitive waytodevelopnaturalgasresources.Preludewillhaveamuchsmaller environmentalfootprintthanland-basedLNGplants,whichrequire majorinfrastructureworks.Italsoeliminatestheneedforlongpipelines toland.”

30. And,Energean’s2017KarishandTaninFieldDevelopmentPlanconcludesthatanFPSOoptionoffersseveraladvantagesovertheonshore/nearshoreprocessingoption,including:anFPSOminimizesworknecessaryinthefield,quickerdevelopmenttime,capitalexpenditureconsiderations,increasedopportunitiestoexport,tie-backofmultiple3rdpartyfields,reducedtechnicalrisk(e.g.hydrateformationinseabedpipelines),enhancedproductrecoveryfromfield,easeofabandonmentafterfieldisexhausted,andsignificantlyreducedenvironmentalfootprint.Evenwithseabedpipelinestransportingdrygastoshore,anFPSOisclearlyasaferoptionforthenearshoreandcoastalenvironment.NobleshouldexploreleasinganFPSOforinitialLeviathandevelopment,totie-intotheseabedpipelineinfrastructuretransportinggastoshoreandintotheINGLsystem.
31. Regardingrelativesecurityrisksofaplatformvs.FPSO/FLNGfacility,a
formerNobleEnergyofficialstatedasfollowstoa2011TelAvivconference: “Planningaterroristattackonanunprotectedoilplatformisassimple ascharteringboats,trainingdivers,andprovidingthemwiththe explosivesrequired.Optionstoreduceriskandmaximizeflexibility couldincludeusingafloatingplatformcapableofprocessinggasinto LNG.Allsecurityeffortswouldbeconcentratedatthedrilling platformandFLNGfacility,therebyreducingother,greaterrisksin naturalgasproductionandtransportation.”
SpillResponse
32. TheLeviathandocumentsoverstatethecapabilitytorespondto(contain/recover)anoffshorecondensaterelease.Itisgenerallyacceptedintheinternationalspillresponsecommunitythatthereexistsnocontainment/recoverymethodologythatwouldbeeffectiveforoffshorecondensate(ornaturalgas)releases.TheTechnicalLeadforOilSpillResponseLimited(OSRL)intheUK,whichisNoble’sTierIIIresponsecontractor,admittedthedifficultyinrespondingtocondensatespillsinareplytotheauthoronthissubject,stating:“Youarecorrectthatinthemajorityofcasesofgasorcondensatereleasesthenit’ssimplyamatterof‘Monitor&Evaluate’withnodirectintervention.”Theassumptionthatallgasandcondensatewillquicklyfloattotheseasurfaceisalsoincorrect,assomemayremainentrainedinmid-layerwatermasses(asinDeepwaterHorizon).
33. Chemicaldispersantsarenotknowntobeeffectiveinmostcondensate
releasescenarios,yettheLeviathanOilSpillContingencyPlan(OSCP)reliesondispersantapplicationasaprimaryresponsetool.Further,currentIsraelidispersantrestrictionsprohibitdispersantuseinwaterdepthslessthan20mdeep,orwithin1nauticalmileofsensitivecoastalhabitats.Thisrequirementneedstoberevisedtoprohibitdispersantuseinwaterslessthan200mdeep,orwithin10milesofshore.Theoperatorshouldberequiredtoconductlaboratorytestsoftheeffectivenessofdispersantson

37. Thereisnodiscussionofsecuringadequatefinancialliabilitycoveragefortheproject,includingenvironmentaldamageandunlimitedliabilityforgrossnegligence.Israelisapartytoseveraloftheinternationaloilpollutionliabilityregimes,butthesealoneareinsufficient.Israelshouldconsideradditionalliabilityrequirementstomotivateresponsiblecorporatebehavior.

39. Theprojectestimateofabout19milliontonsCO2emissionsoverthe30+
yearlifetimeoftheprojectconstitutesadramaticunderestimate.Ifthetotaltheamountofnaturalgasprojectedtobeproduced(22Tcf)fromtheprojectisconsidered,totalCO2emissionsresultingfromtheprojectwouldexceed1.2billiontons.TheGovernmentofIsraelshouldestablishacarbontaxofatleast$60/tonCO2e(comparabletoNorway)onallcarbonemissions.
40. Securityriskoftheproject,particularlyfortheLPPandonshore
infrastructure,isnotsufficientlyconsidered.SecurityriskalonearguesagainsttheLPPoption,infavoroftheFLNGoption125kmoffshore.
41. TheStakeholderEngagementPlan(SEP)reliesonconventionalpassive

Giventheabovesubstantiveconcerns,itismyrespectfulrecommendationthattheGovernmentofIsraelsuspendpermittingfortheLeviathanproject,pendingsatisfactoryresolutionofallissuesraisedherein.Inparticular,theLeviathanprojectshouldberedesignedtoeliminatethenearshoreLeviathanProductionPlatform(LPP)andextensiveseabedpipelineinfrastructure,optinginsteadforeitheranFLNGfacilityoffshoreatthegas/condensatefield125kmoffshore,anduseofshuttletankerstodeliverLNGandcondensatetoIsraelandothermarkets;oralternatively,anFPSOattheoffshoregas/condensatefield,transportingcondensateviashuttletankersanddrygasviaseabedpipelinetoshore.WhileFPSOorFLNGoptionswouldposedifferentrisksthatmustbeaddressed,onbalanceeitherwoulddramaticallyreducenearshorerisksandimpactsoftheproject.
Clearly,themostenvironmentallyresponsibleoptionforLeviathandevelopmentisforNobletodesignandconstructanFLNGfacility.Alternatively,inordertoavoidconstructiondelays,thecompanyshouldconsiderleasinganFPSOforinitialdevelopment,andtie-intoitsseabedgaspipelinesystem(inconstruction)totransportgastoshoreandtheINGLsystem,andcondensateviatanker.NobleshouldofferitsnewlyconstructedLPPforsaletoanotheroffshoregasprojectelsewhere.

Regardingriskofcatastrophicfailureofprojectcomponentsand/oracatastrophicenvironmentalreleaseofhydrocarbons,riskneedstobemethodicallyassessed.Onthis,thedocumentsreviewedsimplydonotprovideenoughdetailtoconfirmthecompany’ssafetyassurances.Ingeneral,thedocumentsoverstatethepotentialeffectivenessoftheproject’sriskmitigationandresponseplans,anditsclaimsregardingriskmitigationarequalitative,vague,andunsubstantiated.
Forinstance,thedocumentsdonotpresentaclearwellblowoutorpipelinespillpreventionplan-justgeneralassurances-includingleakdetection,welldesignandcontrol,pipelinedesign,personneltraining,thirdpartyservices,managementofchange,near-casualtyreportingandinvestigation,riskassessment,andequipmentmaintenanceandsurveillance.ThereisnodiscussionofanOperationsIntegrityManagementSystem(OIMS).

TheDrillingEIAsimplystates:
“Bestindustrypracticewillbeusedduringalldrillingphases.Aftereach newwellisdrilled,itwillbetemporarilyabandonedandsecuredwith multiplebarrierspendingcompletionoperationsbytheseconddrillingrig. TemporaryabandonmentwillbeconductedinaccordancewithMNIEWR guidelines.“
Obviously,thisisinsufficientwithwhichtojudgetherigoroftheproject’ssafetyandspillpreventionsystems(Seebelow).
7.1 Welldesignandcontrol
Theprojectdocumentationneedstorecognize,detail,andconfirmtheprojectwillmeettheincreasedsafetystandardsimposedintheU.S.afterthe2010DeepwaterHorizondisaster.24Inparticular,theprojectdocumentsmustdiscusstheU.S.BureauofSafetyandEnvironmentalEnforcement(BSEE)FinalRule(30CFRPart250)publishedonAugust10,2012:OilandGasandSulphurOperationsontheOuterContinentalShelf–IncreasedSafetyMeasuresforEnergyDevelopmentontheOuterContinentalShelf.ThisoffshoreDrillingSafetyRuleintheU.S.,establishednewcasinginstallationrequirements,newcementingrequirements,requiresindependentthird-partyverificationofblindshearram(BSR)capabilityandsubseaBOPstackcompatibility,requiresnewcasingandcementingintegritytests,establishesnewrequirementsforsubseasecondaryBOPintervention,requiresfunctiontestingforsubseasecondaryBOPintervention,requiresdocumentationforBOPinspectionsandmaintenance,requiresaRegisteredProfessionalEngineertocertifycasingandcementingrequirements,andestablishesnewrequirementsforspecificwellcontroltrainingtoincludedeepwateroperations.

Again,asnotedabove,theLeviathanplanningdocumentsdonotsufficientlyenvisionandplanforcatastrophicfailure,whichtheydoonlysuperficially.Tothecontrary,thedocumentsassumesuccess.Thisattitudeleadstodangerouscomplacencyandlackofvigilance.

Thedocumentsomitreferenceto,orcommitmenttocomplywith,importantAmericanPetroleumInstitute(API)Standards,including,butnotlimitedto,thefollowing:APIStandard53:BlowoutPreventionEquipmentSystemsforDrillingWells;APIRecommendedPractice(RP)65Part2:IsolatingPotentialFlowZonesDuringWellConstruction,addressingbestpracticesforcementing;APISpec16A:SpecificationforDrill-ThroughEquipment;APISpec16D:SpecificationforControlSystemsforDrillingWellControlEquipmentandControlSystemsforDiverterEquipment;APISpec17D:SpecificationforSubseaWellheadandChristmasTreeEquipment;APIRP17H;ISO13628-8:RemotelyOperatedVehicle(ROV)InterfacesonSubseaProductionSystems;andAPIRP75:DevelopmentofaSafetyandEnvironmentalManagementProgramforOffshoreOperationsandFacilities.ManyoftheseareincorporatedbyreferenceintotheU.S.offshoreDrillingSafetyRule(BSEE,2012),withwhichNoblecommitstomeet.

Regardingdrillingrisk,the2011-2012Leviathan2wellcontroleventisinstructive,butnotadequatelydiscussed.Section1.13(p.114)oftheDrillingEIAreportsasfollows:
“DuringdrillingoftheLeviathan-2wellinMay2011,wellboreintegrity issuesoccurredpriortodrillingofthewell’sreservoirsection.Duetothese issues,thedrillingrigwasremovedfromthewell.Followingcessationof drillingoperations(May2011)andpriortothesuccessfulplugging(plug- and-abandonment)ofthewellinSeptember2012,therewasaflowof formationwaterandsubsurfacesedimentsfromthewell….Findingsfromall post-pluggingsurveysconductedtodate(November2012toJanuary2015) suggestthatthepluggingwaseffective(i.e.,noevidenceofaleak),andthat conditionsaregraduallyapproachingnormalconditions(i.e.,decreaseinsize andsalinityofcalderabrinepool).Ithasbeenrepeatedlyshowninprevious reportsthatallenvironmentalimpactsareminimalandhighlylocalized

TheNOP37/HdocumentincorrectlystatesthatFLNGisan“unproventechnology.”WhilesuchFLNGfacilitiesareindeednewdevelopmentsfordeepwater,offshoregasfields,atleasttwoarenowoperational-oneinMalaysia,PetronasPFLNG133,currentlyoperatingattheKanowitgasfieldoffSarawak,Malaysia;andGolar’sFLNGoffCameroon.34

AsShellstatesregardingitsPreludeFLNGprojectoffAustralia:
“FLNGtechnologyofferscountriesamoreenvironmentally-sensitivewayto developnaturalgasresources.Preludewillhaveamuchsmaller environmentalfootprintthanland-basedLNGplants,whichrequiremajor infrastructureworks.Italsoeliminatestheneedforlongpipelinestoland.”36 AndFPSOs(withgas/oilseparation)havebeenusedsuccessfullyforover25yearsfordeepwateroilandgasfields,andtherearepresentlyover200inuseglobally.SomeFPSOsarenowinuseatwaterdepthsfargreaterthanLeviathan,includingtheBWPioneermoored(viaadisconnectableturret)in2,600mdepthintheU.S.GulfofMexico.37

ToavoidconstructiondelaysforLeviathan,NoblecouldleaseanFPSO,andtie-intoitsseabedpipelinesystemnowinconstructiontotransportgastoshore,andshipcondensateviashuttletankers.Asfarascouldbedetermined,anFPSO/FLNGalternativeforLeviathanwasnotfurtherevaluated.Itisimperativethatbothoftheseoptionsarereconsidered. TheSLIP(p.57)states(emphasisadded):
“NobleEnergyassessedavarietyofdevelopmentandtreatmentoptions(i.e., onshore,offshore,sub-sea),includingaFloatingProductionStorageandOff- Loadingvessel(FPSO)withaPressureReductionMeteringPlatform,which wasoriginallypreferred,andaFixedPlatform...Therewerenosignificant environmentaldifferentiatorsorshowstoppersidentifiedacrossallofthe viableoptions.Afixedproductionplatformwaschosen,primarilyinorderto accelerategassupplytothedomesticmarketthusbringingredundancyto Israel’sgassupplyearlier.”
Thisconclusionisclearlynotsupportable,asthereareindeeddramaticenvironmentaldifferentiatorsbetweenthenearshoreplatformandtheFPSO/FLNGoption.

Further,thedocumentsstatethattheactualrationalefordecliningtheoffshoreFLNGalternativeforLeviathaninfavorofmoretraditionaldesign(subseapipelinestoanearshoreprocessingplatform)wasasfollows:

MarineDischarge
10.1 ProducedWaterDischargeProducedwater(condensedwater,formationwater,and‘breakthrough’water)fromthereservoirwillflowinsubseapipelinesalongwithproducedgasandcondensatetotheLPP.ProducedwaterwillbeseparatedanddischargedattheLPP.Israel’sMoEPreports(5/5/2018letterfromMoEPtoGuardians)thattheLPPproducedwatercapacitywillbeonly800m3(8,700bbl)/day,andisexpectedto
52
dischargeapproximately550m3(3,850bbl)/dayofproducedwater.TheLPPwillbefittedwithaproducedwatertreatmentunit,consistingoftwosorbenttanksandonebackuptank.Thisunitisexpectedtobringdischargedpollutantconcentrationsdowntorequiredlimits:under5mg/LBTEX,andunder15mg/Ltotalhydrocarbons.
Still,producedwaterdischargeshouldbeconductedfurtheroffshore.
TheTAMAOffshoreEIAstates(4.8.3):
“…producedwaterisacomplexmixtureoforganicandinorganicsubstances inasolutionandinparticulateform,withawatersalinityrangingfrom almostsweetwatertohighlyconcentratedbrines.Treatedproducedwater containsdispersedoil,awiderangeofnaturalsubstancesinsolution,and lowresidualconcentrationsofgastreatmentadditivessuchascorrosionand sedimentationinhibitors,MEG,andbiocides.Thenaturalsubstancesin typicalproducedwateralsoincludesmallamountsoftoxicsubstancessuch asheavymetals,aromatichydrocarbons,alkyl-phenols,andradioactive substances(OGP2002;OGP2005;Neffetal.2011).”
“Ofmostconcernarethethreegroupsofmicro-components:heavymetals (inorganic),andpolycyclicaromatichydrocarbons(organic),duetotheir toxicityandenduranceinthemarineenvironment,andalkylphenolswhich areknowntodisruptendocrineactivity(Neffetal2011;OGP2005).”
Producedwatertoxicityderiveslargelyfromacombinationofresidualcondensate,iron,ammonia,andhypoxia.Heavymetalsinproducedwatersincludemercury,cadmium,iron,copper,lead,nickel,andchromium,generallyinconcentrationsbetween1mg/Land4mg/L.
Evenwithapredicteddilutionfactorof10,000:1at100mfromthedischargepoint,itisadvisablethatproducedwaterbedischargedfurtheroffshore,offthecontinentalshelf.Adischargepipelineshouldbeextendedatleast10kmoffshore(totalof20kmoffshore),ataminimumof500mdepth,inordertodischargeallproducedwatersfurtherfromproductiveshallowcontinentalshelfwaters.ThephysicaloceanographyintheDrillingEIAreportswatersintheregionarerelativelyisothermalandisohalinebelow500m.Aswell,fluorescencemeasurementsreportpeakphytoplanktonbiomassfrom50m–200mdepth.Thus,dischargeat500mdepth,belowthethermoclineandproductivephoticzone,wouldlimitexposureoftheshallowwatershelfecosystemtotoxicdischargecomponents.
ProducedWaterReinjection(PWRI),inwhichproducedwaterwouldbeseparatedfromthegasstream,pipedbacktotheoffshorefieldandreinjectedintospecificreinjectionwells,wasconsideredanddeclinedintheNOP37/H.WhileadmittingthatPWRIistechnicallyfeasibleandwouldreduceimpacttothemarineenvironment,theoptionisdeclinedastoocostly(100millionEuros)andoflittlenetenvironmentalbenefit.ThedocumentconcludesthatPWRIcannotbeconsidered
53
BestAvailableTechnology(BAT)duetotheircontentionthatthetechnicalfeasibilityofdeepwaterPWRIforgasfields“cannotbeconsideredasproven”;wouldcost100millionEuros;andtheimpactofsuchdischargeis“lowandlimitedtothedirectvicinityofthedischargepoint.”Thisshouldbereconsideredforalloffshoregasprojects,includingLeviathan.BATshouldnotbejudgedbycost,butratherwhetheritindeedisBAT.Clearly,PWRIisBAT.Andregardingtheassertionthatimpactswouldbelowandlimitedtothedirectvicinity,themultiyearimpactofformationwaterreleasedfromthefailedLeviathan2wellshouldbeconsidered.AsdiscussedintheEIA,impactsfromthis2011release(offormationwater,notpetroleum)continuedatleastfor5years.However,evenifPWRIisnotadopted,theprojectshouldatleast,asmentionedabove,berequiredtoconstructadischargepipelinefromtheLPPoffshoreatleast10km(totalof20kmfromshore),inordertodischargeproducedwateroffthecontinentalshelf,inwatersatleast500mdeep.Thisiseasytodesignandaccomplish,andmanycoastalminingcompaniespracticeDeepSeaTailingsDisposal(DSTD)inthismanner,dischargingalltailingsfromcoastalminesoffthecontinentalshelfindeepoceanwaters.Thisisverycost-effective,andwillminimizeimpactstoecologicallyproductivewatersonthecontinentalshelf.10.2 NorwayandU.S.OffshoreDischargeRegulationsTheU.S.EnvironmentalProtectionAgencysummarizesoffshoreoilandgasdischargeregulationsinboththeUnitedStatesandNorway(2011).56Section402oftheU.S.CleanWaterActauthorizestheU.S.EPAtoregulatemarinedischargesthroughtheNationalPollutantDischargeEliminationSystem(NPDES),requiringcompliancewithOceanDischargeCriteriaguidelines.Norway’sPollutionControlActauthorizestheNorwayClimateandPollutionAgencytoregulateoffshoredischarges,includingdrillingfluidsandmuds,producedwater,andotherchemicals.Norwayrequireszerodischargeof“environmentallyhazardoussubstances,”usingBestAvailableTechniques,yetimposesastrictzerodischargerequirementinmoreecologicallysensitiveArcticwatersabove68°N.Forcoastalfacilities(within3milesofshore),U.S.regulationprohibitsdischargeofalldrillingfluids,cuttings,anddewateringeffluent(exceptCookInletAlaska,wherespecificacutetoxicityrequirementsmustbemet).Foroffshorefacilities(outsideof3miles),waterbaseddrillingfluidsandcuttings,andoil-basedcuttingsarerequiredtomeettheacutetoxicitystandard,anddischargeofoil-baseddrillingfluidsisprohibited.Forproducedwaters,theU.S.prohibitsdischargenearshore(exceptCookInletAlaska,whereoillimitsare42mg/L(ppm)daily,and29mg/Laverageoveramonth),asisrequiredoffshore.Israelilawsimilarlylimitshydrocarbondischargeconcentrationto29mg/Laverageoveronemonth.Southof68°N,Norwaypermitsproducedwaterdischargewithcomponentsthat“PoseLittleorNoRisk”(PLONOR),

andlessthan30mg/Lofoilmonthlyaverage.Northof68°N,producedwaterdischargeisnotpermitted(exceptfor“operationaldeviations,”andthenamaximumof5%ofproducedwatersmaybedischarged).WhileIsraelirequirementsfortotalhydrocarbonconcentrationinproducedwaterdischargearesimilartothoseofcoastalU.S.andNorwaybelow68°N,Israeldoesnotregulateheavymetalconcentrationindischarge.Clearly,thehigheststandardiszerodischarge,suchasinNorwegianArcticwaters.ItisrecommendedthattheGovernmentofIsraelconsiderincorporatingtheNorwayArcticstandardintoIsraeliregulation,prohibitingmarinedischargeofalldrillingfluids,cuttings,andproducedwaters.10.3 EmissionsMonitoringandReportingItisunclearwhetherIsraelregulationrequiresreal-timeemissionsmonitoringandreportingbyoffshoregasfacilities,bothatmosphericandmarine.Thismustbeclearlyprovidedinregulation,asitconstitutesbestgovernment/industrypractice.IntheU.S.GulfofMexico(wheremostU.S.offshoreproductionoccurs),theU.S.BureauofOceanEnergyManagement(BOEM)requiresevent-basedreportingofairemissionsfromalloffshoreoilandgasfacilitiesthroughitsGulfwideOffshoreActivityDataSystem(GOADS).57Thissystemrequiresoperatorstoreportairemissionsthroughstandardizedcomputersoftwaresystem.AsimilarmonitoringandreportingsystemshouldberequiredbylawinIsraelforalloffshoreoperators,forbothatmosphericemissionsandmarinedischarges.11. FinancialLiability
Animportantcomponentofoffshoredrillingsafetyisanadequateliabilityregimethatimposessufficientfinancialliabilityforcorporatenegligence,inordertomotivateeffectivesafetymanagementbythecompany.Whilethereareinternationalliabilityregimescoveringoiltankerspills,bunkerspills,andhazardousandnoxiouschemicalspills,thereispresentlynointernationalliabilityregimecoveringoffshoreoilandgasdevelopment.Fornow,thisislefttocoastalstatejurisdiction.
WhileIsraelisapartytothe1992IOPCFundConventionandthe1992CLC,itisnotpartytotheSupplementaryFundProtocolprovidinggreatercoverageforcrudeoiltankerspills;the2001BunkerSpillConvention(coveringheavybunkerfuelspills);orthe2010HazardousandNoxiousSubstances(HNS)Convention(coveringnaturalgasandcondensatereleases.)
Directive2013/30/EUonSafetyofOffshoreOilandGasOperations(EU,2013)requiresallmemberstatestoensurethatanoffshoreoilandgasoperator:
“…isfinanciallyliableforthepreventionandmediationofenvironmental damage...fromoffshoreoilandgasoperations.”
55
ThisshouldbethecaseinIsraelaswell.Inthisregard,Israel’snationalliabilityprovisionsforoffshoregasdevelopmentandtransportationshouldbethoroughlyreviewedandupdatedtoensuresufficientcoverageofaWorstCaseDischargefromanyoftheoffshoregasprojects.Thiscanbedoneeitherthroughtheinternationalregimes,ormoreappropriately,throughnationallegislation.GiventhattheBPspillintheGulfofMexicohascostBPover$61billionUSD58,theGovernmentofIsraelshouldestablishunlimitedliabilityforoffshoredrillingprojects(atleastincasesofgrossnegligence).ThegovernmentshouldalsoensurethatNoble,itspartners,rigowners,andsubcontractorsarejointlyliable,andhavesufficientinsurancecoverageand/orbondingtocoverallcosts(includingenvironmentaldamage)foraWorstCaseDischarge.Aswell,Israel’scriminalliabilityforgrossnegligenceinindustrialoperationsshouldbereviewedandenhancedasappropriate.Thisshouldbediscussedinthedocuments.
TheGovernmentofIsraelshouldestablishanationalOilSpillPreventionandResponseFund,derivedfromanominal(e.g.,0.10Euro/bbl)assessmentonalloilandgasproducedorimportedintothecountry,asmanyothergovernmentshavedone.ThisFundshouldbeusedbythegovernmenttoenhanceitsoversightofoilandgasspillpreventionandresponsepreparedness,inparticularitsoversightcapabilitiesregardingoffshoregasexplorationandproduction.ThecomparablefundintheU.S.istheOilSpillLiabilityTrustFund,derivedfroma$0.09/bblfee,currentlywitha$5billioncurrentbalance.59
12. CO2EmissionsThedocumentspredictthetotalCO2(equivalent)emissionfromconstructionphaseoftheprojectwillbe911,397tons;fromoperationspre-2024atotalof2,416,105tons;andfrom2025–2050(projectdesignlife)atotalof15,416,825tons.Thus,totalCO2eemissionspredictedfromtheprojectperseareestimatedat18,744,327tons.However,thisestimatedoesnotincludeemissionsfromthe22TcfofnaturalgasthatwillbeproducedbytheLeviathanproject.UsingtheUSEPAconversionof0.0550tonCO2/Mcfgas,combustionof22Tcfofgaswillemitapproximately1.2billiontonsCO2e.Inaddition,theprojectestimatelikelydoesnotincludemethaneleakagefrompipelinesoverthe30+yearlifetimefortheproject.Thesesourcesshouldbeaccuratelyandhonestlyreflectedinprojectdocuments.Thepotentialfinancialimplicationoffuturecarbonpricingforthisamountofemissionsshouldbeconsidered,andfactoredintotheproject’sfinancialfeasibilityanalysis.TheGovernmentofIsraelshouldestablishacarbontaxofatleast$60/tonCO2e(comparabletoNorway)onallcarbonemissions.

13. SecurityRiskIngeneral,thesignificantsecurityandterrorismriskposedbytheproject,inparticularattheLPP,hasnotbeenadequatelyaddressedinprojectdocuments.Giventhewell-knownsecuritythreatsintheregion,thisisasignificantgapinprojectriskassessmentandmustberemedied.Infact,theentireIsraelNaturalGasLine(INGL)systemshouldbesubjectedtorigorousandcomprehensivesecurityassessmentandplan(ifithasn'talready).Ascurrentlydesigned,theLeviathanprojectpresentssignificantsecurityrisktothepublicandenvironmentofIsrael,includingthepotentialforprojectinfrastructuretobeintentionallydamagedordestroyed,leadingtodisruptionofenergyservicesonshore;masscasualtiesand/orhealthimpacts;anddisruptionofcommerceandpublicservices.Securitymeasuresshouldbeintegratedintoprojectdesignandconstruction.Thisissuedeservesconsiderablymoredetailinprojectdocuments.Asdiscussedabove(inProjectDesign,Platformvs.FLNG),acentralissueinriskevaluationoftheLeviathanProductionPlatformisthepotentialforhostilitiesbetweenHezbollahandIsraelalongtheborderwithLebanon(asin2006).Insuchasituation,anFPSO/FLNGfacility125kmoffshoreissignificantlylessatriskthanaprocessingplatformonly10kmoffshore.Ifhostilitiesweretoensueagain,anearshoregasprocessingplatformclosetotheborder(e.g.,LPP)wouldlikelybehighonanadversary’stargetlist.Asdiscussedabove,thisriskwouldbesignificantlyreducedbyselectinganFPSO/FLNGfacility125kmoffshoreforLeviathan.
Israel(andNobleEnergyanditspartners)nowfacesignificantsecuritychallenges,whichwillincreasesubstantiallyasthenewdiscoveriesaredeveloped.
ThesecurityriskposedbyLeviathan(andotheroffshoregasfieldsofIsrael)wasdiscussedin2011byformerNobleEnergyofficialAbrahamD.Sofaer,asfollows60:

Asdiscussedabove,anFLNGfacilityshoulddevelopacontingencyplanintheeventofhostilities,inwhichitwouldclosedownallproductionandmoveoffsiteandoutofrangeofpotentialhostileaction.SucharesponsewouldbeunavailabletothestationaryLPP.Atveryleast,NobleshoulddevelopacontingencyplanforshuttinginandevacuatingtheLPPintheeventofseriousthreatduringarmedconflict.

14. StakeholderEngagementTheStakeholderEngagementPlan(SEP)outlinedinprojectdocuments(inparticularAppendix2oftheSLIP),isclearlyinsufficient.Noblestates: “NobleEnergyiscommittedtoestablishingandmaintainingtransparent, respectfulandregularengagementpracticestounderstandandmanage stakeholderconcernsandinterests.Thesepracticesareaboveandbeyond theengagementactivitiesmanagedbyIsraeligovernmentagenciesasapart ofthepermittingprocesses.”
First,giventheextensiveamountofredactionofsystems-criticalinformationinprojectdocuments,aswellasthefailuretopubliclyreportthe2011Leviathan2explorationwellfailure,theaboveassertionisquestionable.Moreimportantly,theStakeholderEngagementPlanreliesontraditionalpassiveengagement,whichforaprojectofsuchcomplexityandpotentialconsequenceisinsufficient.Passiveengagementconductedbytheproponentstodate(citedinthe2016SLIP)providessimplythat: “…thirdpartiespotentiallyaffectedbyprojectdevelopmentareprovided withopportunitiestoreviewprojectinformationandprovidecomment.”
Theoilandgasindustry’sconventionalpassivestakeholderengagementprocessprovidesthousandsofpagesofdetailed,technicaldocumentsforpublicreviewandcomment,publichearings,publicrelationscampaigns,etc.,butthisisknowntobeaninsufficientmethodforobtainingauthentic,informedpublicengagement.Foraprojectwiththetechnicalcomplexity,risk,andpotentialconsequencetothepublicinterestofIsrael,amoredeliberateSEPprocessmustbeestablished.Forthat,IrecommendestablishmentoftheIsraelOffshoreCitizens’AdvisoryCouncil.66Large-scaleresourcedevelopmentprojectssuchasLeviathan(Tamar,andotheroffshoregasdevelopments)generallyreceiveinsufficientoversightby,andengagementwith,civilsociety.Whileindustryandgovernmentmayprovidetransparency,thisinitselfdoesnotconstituteeffectivecivilsocietyengagement.Membersofthepublicoftenhaveinsufficienttime,financialability,andtechnicalexpertisetoengageeffectivelyincomplexresourcedevelopmentandpolicyissuessuchasLeviathan.
TherecanbeanoverwhelmingamountofinformationavailableregardingprojectssuchasLeviathan,muchofittechnicalandunfamiliar,andevenmultipleprojectsandpolicyissuesintersectingsimultaneously,makingitdifficultforcitizenstoassimilatepertinentinformationandprovideinformedcomment.Whileoutside

Andintheabsenceofeffectivepublicengagement,corporateandgovernmentvigilancecanweaken,complacencyincreases,environmentalandsocialstandardsdecline,andrisksincrease.Suchinsufficientoversight,lowerstandards,andcomplacencycanresultinacuteandcatastrophicresults;suchasoilspills;long-term,chronicenvironmentaldegradation;andsocialtension,mistrust,litigation,andevenviolencebetweenlocalpeopleandindustry.
Tocorrectthisproblem,localcivilsocietystakeholdersneedtobedirectlyinvolvedinthereviewandoversightofresourceindustryoperationsthatpotentiallyaffecttheirlives,inparticularextractiveindustriessuchasoil,gasandmining.Andtoeffectivelyengage,citizenstakeholdersneedtheirownorganizationwithsufficientfunding,staff,authority,broadrepresentation,andindependence.
Additionally,astheGovernmentofIsraelisbothfinancialbeneficiaryandregulatoroftheproject,ithasaninternalconflictofinterestinprovidingeffectiveoversight.
14.1 IsraelOffshoreCitizens’AdvisoryCouncil
Thus,itisproposedherethattheGovernmentofIsraelrequiretheestablishmentofanIsraelOffshoreCitizens'AdvisoryCouncil(IOCAC)asapre-conditionforfinalgovernmentapprovaloftheLeviathanproject.Modeledlooselyonthetwooiloversightcitizens’councilsinAlaska(www.pwsrcac;www.circac.org),aswelltheShetlandOilTerminalEnvironmentalAdvisoryGroup,or“SOTEAG”,inScotland(www.soteag.org.uk/),theIOCACwouldprovidestructured,non-binding,informedpublicadvice,oversight,andengagementwithalloffshorepetroleumdevelopmentinIsrael’sEEZ.
ItisproposedthattheIsraelCouncilbeguaranteedabudgetofapprox.$5millionUSD/year,eitherfromgovernmentresourcerevenuesfromtheprojects,ordirectlyfromtheoffshorepetroleumindustry(e.g.,Nobleanditspartners).Bycomparison,ourPWSRCACreceivesapproximately$4million/yearfromtheownersandoperatorsoftheTransAlaskaPipelineSystemMarineTerminalinValdezAlaska.Asproposed,theIsraelCouncilwouldhaveabroadermandate,andcovertheentireoffshoreEEZofIsrael.Thus,abudgetof$5million/yearseemsappropriate.
TheIsraelCouncilshouldbecomprisedofallmajorstakeholderconstituenciespotentiallyaffectedbyoffshoreindustry–e.g.,fishing,aquaculture,conservation,tourism,women,youth,science,andlocalcommunities.Properlystructured,theIOCACwillbecometheeyes,ears,andthevoiceforlocalcitizensregardinglarge-scalepetroleumdevelopmentinIsrael’sEEZ,andaugmentgovernmentandindustryoversightoftheoffshoreprojects.
TheCouncilshouldhaveaBoardofDirectorsrepresentingallmajorstakeholders,
62
paidstaffforday-to-dayoperation,andsub-committeesasappropriatetoitsmission.ThebroadmissionoftheIOCACwouldbetoenablecitizenstakeholderstoensurethehigheststandardsofenvironmentalandsocialresponsibilityofalloffshoreindustrialprojectsand/orallindustrialactivityinIsrael’sEEZ.Itsgoalistoreducethedeleteriousenvironmentalandsocialimpactandriskofresourcedevelopment,andenhancecommunicationandengagementbetweencivilsociety,industry,andgovernment.
Specifically,theCouncilshouldprovideoversight,advice,andadvocacyonissuessuchaswheretopermitadditionaldevelopment,BestAvailableandSafestTechnology(BAST)standards,biodiversityconservation,riskassessmentandaccidentprevention,responsepreparedness,liabilitystandards,environmentalmonitoring,biodiversityoffsets,invasivespeciescontrol,socialimpactmitigationprograms,transportroutesandmethodologies,regulatoryreform,governmentrevenuesandtaxes,wastemanagement,remediationandrestoration,laborpractices,humanrights,humanhealth,andsoon.TheCouncilshouldreviewandsubmitwrittencommentsonallexistingandproposedprojectoperations.Thiscanincludelegislation,regulationsandpermits,andindustrypolicy,procedures,andfinancialmatters.
AttherequestofitsBoardorcommittees,theIOCACshouldcommissionindependentscientificstudies,consultancies,andreportsonissuesofinterestorconcerntoitsstakeholders.Thisresearchshouldcontributetothefactualbasisofthecouncil’spolicyrecommendationstoindustryandgovernment.
TheCouncilwillprovideanon-going,structuredmechanismforgreatercommunication,collaboration,andtrustbetweencitizens,government,andoffshoreindustry,andshouldreduceindustry’senvironmentalimpact,risk,andfootprint.Thecitizens’councilwillnotsubstituteforeffectivegovernmentaloversight,butwillcomplementandenhancesuch.TheestablishmentofthisproposedCouncilisfundamentaltoindustry’s“sociallicensetooperate,”genuinecorporatesocialresponsibility,citizenempowerment,environmentaljustice,governmentlegitimacy,andsustainabledevelopment.Assuch,thecitizencouncilwillprovidelong-termbenefittothepublic,government,andindustry.
