4.0 ENVIRONMENTAL IMPACT ANALYSIS F. HAZARDS AND HAZARDOUS MATERIALS

1. INTRODUCTION

This section analyzes the potential impacts associated with hazards and hazardous materials that couldresult from implementation of the Project. The analysis considers potential impacts associated with thehistorical use of hazardousmaterials on the Project Site and the transport, use, or disposal of hazardousmaterials that couldoccurduringconstructionandoperationof theProject. Theanalysis included in thissectionisbasedonthePhaseIEnvironmentalSiteAssessment(PhaseIAssessment)andHazardousBuildingMaterialSurveyprepared for theProject,whichcollectively identify thepotentialenvironmental concerns(PECs)andrecognizedenvironmentalconditions(RECs),asdefinedinestablishedprofessionalstandards,onthe Project Site. The Phase I Assessment andHazardous BuildingMaterial Survey containmore detailedinformationthanissummarizedbelowandareprovidedinAppendixEofthisDraftEIR.

Oneotherhazards‐related topic, groundwater, is addressed indetail in Section4.G.,Hydrology andWaterQuality,ofthisDraftEIR.

2. ENVIRONMENTAL SETTING

a. Historical Site Uses

TheHarbor‐UCLAMedicalCenter,originallynamed theLosAngelesCountyHarborGeneralHospital from1951to1978,wasfoundedin1943astheU.S.Army’sPortofEmbarkationStationHospital,areceivingpointand hospital for servicemen returning from the Pacific during World War II. Facilities included anadministrationbuilding, a collection ofArmybarracks and cottages, and a hospital that providedmedicalservicesforservicemenandtheirfamilieslivinginthearea.By1946,thefacilitywassoldaswarsurplusbythefederalgovernmenttotheCountyforthedevelopmentofLosAngelesCountyHarborGeneralHospital(HarborGeneralHospital), toprovideCounty‐basedmedical careandhospital services to the increasinglypopuloussouthwesternpartoftheCounty.

Theexistinghospitalbuilding(ExistingHospitalTower),locatedintheeasternportionoftheCampus,wasdevelopedonpreviouslyvacantlandandcompletedin1962.TheHospitalreplacedanumberoftheoriginalArmyfacility’swoodenbarracksandcottages.Nearlyone‐thirdoftheoriginalbarracksremaininusetodayas clinics, offices, shops, storage, laboratories and related facilities, augmented by temporary modularbuildingsandtrailers.

Notes:

a Secondary containment is a means of surrounding one or more primary storage containers to collect any potential hazardous material spillage in the event of loss of integrity or container failure. Hazardous materials are stored in secondary containment to prevent or minimize the possibility of accidental release.

(d) Asbestos‐Containing Materials (ACMs)

Asbestos is anaturally‐occurringmineralmadeupofmicroscopic fibers thathasbeenwidelyused in thebuildingindustryforavarietyofuses.Suchusesincludeacousticandthermalinsulationandfireproofing.Itis often found in ceiling and floor tiles, linoleum, and pipes, as well as on structural beams and asphalt.However,asbestoscanbecomeahazardwhenthefibersseparateandbecomeairborne.Asbestoshasbeenlinkedwithlungdiseasescausedbyinhalationofairborneasbestosfibers,anditsuseinbuildingwasbannedby1978.

Based on the age of the building construction (prior to 1980), it is possible that ACM is present in thestructures.ACMsobservedattheHarbor‐UCLAMedicalCenterincludesdrywall,jointcompound,vinylfloortile,mastic, insulation, cloth tape, coating, caulking, acoustic ceiling tile, gray carpet,buttonboard, transitepipe,linoleum,ducttape,venttape,whitecovebase,glue,asphaltshingles,thermalsysteminsulation,silverpaint, and sealant. (Detailed results froman asbestos survey areprovided inTable 1 of theHarbor‐UCLAHazardousBuildingMaterialSurveyinAppendixE.)Priortorenovationordemolitionactivitieswhichwoulddisturb identifiedACMs, a licensed abatement removal contractor shall be contacted to remove theACMsandperformstabilizationactivitiesasrequired.

(e) Lead‐Based Paint (LBP)

Leadisanaturallyoccurringelementandheavymetalthatwaswidelyusedasamajoringredient inmostinterior and exterior oil‐based paints prior to 1950. Lead compounds continued to be used as corrosioninhibitors,pigments,anddryingagentsfromtheearly1950sto1972,whentheConsumerProductsSafetyCommissionspecifiedlimitsonleadcontentinsuchproducts.Lead‐basedpaint(LBP)isofconcernbothasasourceofexposureandasamajorcontributortoleadininteriordustandexteriorsoil.Basedonthedateofbuildingconstruction,itispossiblethatLBPhasbeenusedonthepropertyinthepast.Forthepurposesofidentifying LBP on the site and for the Lead‐Containing Surfaces (LCS) Survey, any lead‐based surface isconsidered a LCS. (Detailed results from the LCS survey are provided in Table 2 of the Harbor‐UCLAHazardous Building Material Survey in Appendix E.) Identified LCSs shall not be disturbed. Prior torenovation or demolition activities which would disturb identified LCSs, a licensed abatement removalcontractorshouldbecontactedtoremovetheLCSsandperformstabilizationactivitiesasrequired.

The Federal Resource Conservation and Recovery Act (RCRA) (42 U.S.C. secs. 6901‐6992k) regulates thegeneration, transportation, treatment, storage,anddisposalofhazardouswaste. UnderRCRAregulations,generatorsofhazardouswastemust registerandobtainahazardouswasteactivity identificationnumber.RCRAallowsindividualstatestodeveloptheirownprogramfortheregulationofhazardouswasteaslongasit is at least as stringent asRCRA. The State of California has developed the CaliforniaHazardousWasteControlLaw(HWCL)(HealthandSafetyCodesec.25100etseq.and22CaliforniaCodeofRegulations[CCR]sec. 66260.1 et seq.) and the U.S. Environmental Protection Agency (USEPA) has authorized RCRAenforcementtotheStateofCalifornia.PrimaryauthorityforthestatewideadministrationandenforcementofHWCLrestswithCaliforniaEPA’s(Cal‐EPA)DepartmentofToxicSubstancesControl(DTSC).

(a) Underground Storage Tanks (USTs)

Underground Storage Tanks are regulated under Subtitle I of RCRA and its regulations which establishconstruction standards for new UST installations (those installed after December 22, 1988), as well asstandards for upgrading existingUSTs and associatedpiping. Since 1998, all non‐conforming tankswererequiredtobeeitherupgradedorclosed.

The State regulatesUSTspursuant toHealth and Safety Code,Division 20, Chapter 6.7, andCCRTitle 23,Division 3, Chapter 16 and Chapter 18. The State’s UST program regulations include among others,permittingUSTs,installationofleakdetectionsystemsand/ormonitoringofUSTsforleakage,USTclosurerequirements, release reporting/corrective action, and enforcement.

(1) Hazardous Materials Management

ThresholdHAZ‐1:WouldtheProjectcreateasignificanthazardtothepublicortheenvironmentthroughtheroutinetransport,use,ordisposalofhazardousmaterials,orthroughreasonablyforeseeableupsetandaccidentconditionsinvolvingthereleaseofhazardousmaterialsintotheenvironment?

Impact StatementHAZ‐1: Project construction involves the demolition of existing buildings, grading, andexcavation,which could result in the potential release into the environment of hazardousmaterialsduring removal and/or remediation of existing on‐site USTs, ASTs, PCBs, ACMs, and LBP, or thedisturbance of on‐site soil that may be contaminated by past USTs on the Campus or underlyinggroundwater that may be contaminated by nearby off‐site LUSTs. These represent potentialenvironmentalconcernsontheHarbor‐UCLACampusandtheirdisturbanceisconsideredapotentiallysignificantimpact.Projectoperationswouldrequirethestorage,use,anddisposaloflimitedquantitiesof hazardous materials and waste routinely used in hospitals and related facilities, in a mannerconsistent with manufacturer’s recommendations and applicable regulatory requirements. Thepotential for upset and accidental conditions resulting in the release of thesematerials is low andrelatedimpactsareconsideredlessthansignificant.

The Harbor‐UCLA Medical Center Campus Master Plan Project would include the following: (1) a NewHospitalTower;(2)newandrenovatedoutpatientcarefacilities(tobeprovidedinnewoutpatientbuildingsand in portions of the renovated Existing Hospital Tower); (3) other services and facilities, including



administrative office, warehouse/storage areas, day care, limited commercial services (e.g., coffee stand,sundry shop); (4) long‐term buildout of the LA BioMed Campus; (5) new Bioscience Tech Park; and (6)Medical Center Campus support facilities, including new and renovated infrastructure, utilities, parking,roadways, and pedestrian and bicycle circulation improvements. Some existing buildings would bedemolishedandreplacedwhileothers,suchastheExistingHospitalTower,wouldbemodifiedfordifferentuses. Projectconstruction,tobeimplementedinphasesoverthecourseofapproximately15years,wouldrequiretheremediationofbuildingsandequipmentidentifiedashavingACMs,LPB,andPCBs;theremovaland/or relocationofUSTsandASTs thatpresently contain,orhavecontained in thepast, fuels andotherpotentially hazardous materials; and the disturbance of soil potentially contaminated with hazardousmaterialsastheresultofon‐siteoroff‐siteLUSTs. Remediationofthesematerialswouldbeconductedbyqualifiedprofessionals inaccordancewithregulationsgoverningtheseactivities, includingSCAQMD’sRule1403(ACBMs);Cal‐OSHArules(LBP);thefederalToxicsSubstancesControlAct(PCBs);and,forUSTs,RCRASubtitle I, the State Health and Safety Code, and LAFD’s enforcement of the State’s applicable CCRregulations,withoversightbytheRWQCBwheregroundwatermaybeaffected.Nonetheless,construction‐relatedactivitieshavethepotentialtoresultinaccidentalupsetandreleaseofhazardousmaterialsintotheenvironment,whichisapotentiallysignificantimpact.

Construction also would involve the short‐term use and disposal of hazardous substances such as paint,adhesives,surfacecoatings,finishingmaterials,andcleaningagentsduringbuildingfinishingactivities.Theuseanddisposalofsuchmaterialswouldtakeplace inaccordancewithapplicable federal,state,and localregulationsgoverninghealthandsafetyandsuchactivitiesarenotanticipatedtocreateasignificanthazardtothepublicorenvironment.Relatedimpactswouldbelessthansignificant.

Projectoperationswould involve theuseandstorageof limitedquantitiesofhazardousmaterials suchascleaning solvents, painting supplies, andpesticidesused for landscaping. Additionally,wast generatedbygeneralhospitaloperationstypicallyincludesregulatedmedicalwaste,“sharps”containers,pharmaceuticalwaste,chemowaste,andpathologicalwaste,andthenatureoffuturehospitaloperationsontheCampuswillnotsignificantlydifferfromexistingdailyoperations.Furthermore,futureexpandedLABioMedoperationsandoperationoftheproposedBiotechScienceCampusontheHarbor‐UCLACampuswouldinvolvetheuseoflimitedquantitiesofpotentiallyhazardousmaterialstypicalofthoseusedinbiomedicalresearchfacilities.AllpotentiallyhazardousmaterialsandwastehandledontheHarbor‐UCLACampuswouldbeused,stored,anddisposedofinaccordancewithmanufacturerinstructionsandapplicablefederal,state,andlocalhealthand safety regulations. Accordingly, impacts related to the routine transport, use, and disposal of suchmaterialswouldbelessthansignificant.

Mold,radon,andleadindrinkingwaterwerenotconsideredtorepresentanenvironmentalconcernattheProject Site. The Project Site is also not located within a methane hazard site or buffer zone. Projectimplementationwould,therefore,resultinlessthansignificantimpactswithrespecttothesehazards.

There are no schools within aquarter‐mile of the Harbor‐UCLA Campus and impacts related to the emissions or handling ofhazardousmaterialsincloseproximitytoschoolswouldbelessthansignificant.However,achildcarefacilitylocatedimmediatelynorthoftheMedicalCenterCampus,whichcouldbepotentiallyaffectedbyaccidentalreleasesofhazardousmaterials. Assuch, impacts inthisregardareconsideredpotentiallysignificant.

Thereare11publicschoolswithinathree‐mileradiusoftheHarbor‐UCLACampus,butnopublicorprivateschools within a quarter‐mile. Although Project construction activities could result in the release ofhazardousmaterials, such releaseswouldnot takeplacewithin aquarter‐mileof anexistingorproposedschoolandthepotentialforimpactsonschoolswouldbelessthansignificant.Althoughnopublicorprivateschools are located in proximity to the Medical Center Campus, the Harbor‐UCLA Kindercare child carecenter is locatedalongthenorthsideofCarsonStreetapproximately200feetnorthof theMedicalCenterCampus. Since constructionactivitieswouldhavea limitedpotential to result in the incidental releaseofexisting sources of contamination, and thus could affect children and staff at the facility, impacts to theexisting child care facility would be considered potentially significant. However, implementation ofapplicable mitigation measures identified below would reduce the potential for adverse effects on theexistingchildcarecentertoacceptablelevels.

ThresholdHAZ‐3: WouldtheProjectbelocatedonasitethatisincludedonalistofhazardousmaterialssites compiled pursuant to Government Code Section 65962.5 and, as a result, could create a significanthazardtothepublicortheenvironment?

Impact StatementHAZ‐3: Harbor‐UCLA is listed on several environmental databases due to inconclusivedocumentation regardingproper remediationand site closure following1994 removalof fiveon‐siteUSTs, aswell as the presence of Large and Small Quantity Generators of hazardous waste on theCampus. Four adjacent off‐site properties to the eastwere also listed due to the potential for LUSTpetroleumhydrocarboncontaminationofunderlyinggroundwater.AsstatedunderThreshold/ImpactStatementHAZ‐1,constructioncouldresultinthereleaseofhazardousmaterialsduetodisturbanceofpotentially contaminated on‐site soil and/or groundwater; this is a potentially significant impact.HazardouswastegeneratedduringProjectoperations isnotconsideredahazardtohumanhealthortheenvironmentandrelatedimpactswouldbelessthansignificant.

Documentationofcleanupactivitiesatthislocationdoesnotextendpast2000andit isnotclearwhether proper soil excavation, soil vapor remediation, and site closurewere completed. Moreover, thepotential extent of possible contamination of underlying groundwater with petroleum hydrocarbonsoriginatingwithnearbyoff‐siteLUSTsisnotknown,althoughthepotentialforProject‐relatedexcavationtointercept groundwater at depths of 48‐60 feet bgs, or historic high groundwater at 30 bgs, is low.Nonetheless,Projectconstructionactivitieshavethepotentialtoresultinasignificanthazardtothepublicor environment as the result of disturbance of potentially contaminated soil and groundwater due to theunknowncleanupstatusofthedocumentedUSTs.Thisisconsideredapotentiallysignificantimpact.

Thenearest airports to theHarbor‐UCLACampus include Zamperini Field inTorrance (fourmiles away),HawthorneMunicipal Airport (sevenmiles away), Compton/Woodley Airport (ninemiles away), and LosAngeles InternationalAirport (elevenmiles away). Becauseof thisdistance,Projectoperations, includinghelicopter operations, are not anticipated to interfere with operations of these or any other airports orairstrips.

(3) Emergency Response Plans

ThresholdHAZ‐5: Would the Project impair implementation of or physically interferewith an adoptedemergencyresponseplanoremergencyevacuationplan?

ImpactStatementHAZ‐5: Impactsregardingemergencyresponseplanswouldbe lessthansignificant. TheProjectwouldnotusehazardousmaterialsorhaveon‐sitehazardous conditions thatwould conflictwith or obstruct implementation of any emergency response plans. Further, the Projectwould notinterferewithemergencyaccessroutes.

There are no current or anticipated future conditions on the Harbor‐UCLA Campus that would impairimplementationof anyexistingemergency responseplansorevacuationplans. ThepresenceofpotentialandrecognizedenvironmentalconditionssuchasPCBs,ACMs,andLBPinon‐sitebuildingsandtheremovalofASTsandUSTsandanyassociated soil or groundwater contamination,wouldbeadequately addressedthroughrequiredcompliancewithregulationsgoverningpublichealthandsafety,aspreviouslydiscussedunderThreshold/ImpactStatementHAZ‐1.

TheProjectwouldnotrequiretheuseofhazardousmaterialsforconstruction,otherthansuchmaterialsasas paint, surface coatings, and other materials during building finishing activities, as discussed underThreshold/Impact StatementHAZ‐1. With respect to operations, the use and disposal of such hazardousmaterials as cleaning solvents, painting supplies, and pesticides, aswell asmedicalwaste and hazardousmaterials associatedwith biomedical operations,would take place in accordancewith applicable federal,state, and local regulationsgoverninghealth and safety and suchactivities arenot anticipated to create asignificanthazardtothepublicorenvironment.Relatedimpactswouldbelessthansignificant.



The Project would implement on‐site provisions for public safety, including plans to address on‐siteemergencyincidents.Forfurtherdiscussion,refertoSection4.K.1,FireProtectionandEmergencyMedicalServices,andSection4.K.2,PoliceProtection.

Implementation of the Master Plan Project would not adversely affect existing emergency access routes.AlthoughCampusingressandegresswouldbemodifiedtocreatedistinctionsbetweenaccessandparkingfor thegeneralpublicandstaff, includinganewsignalizedpublicentranceonCarsonStreetaswellasanunsignalized staff entranceonVermontAvenuewouldbe created. Vehicular access and circulationwouldavoid conflicts with traffic movements on local roadways and would facilitate the provision of on‐siteemergencyservices.Duringconstruction,adjacentstreetsmaybetemporarilyaffectedduetoconstructionactivity, such as temporary lane closures. Such occurrenceswould be implemented in accordancewith aconstructiontrafficmanagementplan,asstatedinSection4.L.,TransportationandTraffic,ofthisDraftEIRwhich would allow for responses to emergency accessibility needs. The existing helistop would betemporarilyrelocatedtothewesternendoftheCampusduringconstructionoftheNewHospitalTower,andaccommodationswouldbemadetopatienttransportbetweenthetemporaryhelistopandExistingHospital,untilsuchtimeasthenewpermanenthelistopisoperationalaspartoftheNewHospitalTower.

These Project features, together with regulatory compliance, would avoid the need to generate newemergency plans beyond those that would normally be implemented to address on‐site emergencysituations, and would avoid adverse impacts regarding the implementation of existing evacuation plans.Relatedimpactswouldbelessthansignificant.

e. Cumulative Impacts

As described under Existing Conditions, the Phase I Assessment identified all potentially hazardousconditionsintheProjectvicinityandconcludedthatbasedondistance,topography,assumedgroundwatergradient,currentregulatorystatus,and/ortheabsenceofreportedreleases,noneof thesitessurroundingthe Project Site listed in agency databases are considered to represent a likely past, present, ormaterialthreatofreleasethatwouldadverselyaffecttheProjectSite.Thiswouldalsobethecasefordevelopmentonnearbyproperties.

All development in the Project vicinity would be subject to the same local, regional, State, and FederalregulationspertainingtohazardsandhazardousmaterialsastheHarbor‐UCLAMasterPlan.Therefore,withadherence to such regulations, the Project’s incremental contribution to cumulatively significant impacts,consideredtogetherwithrelatedprojects,wouldbelessthancumulativelyconsiderable.
