1. Objective of the Terms of Reference (TOR) Public Consultation

Tocollectcommentsfromrelevantstakeholdersontheprojectobjectivesandthe technical methodology, proposed by the proponent, to carry out theEnvironmental Impact Assessment (EIA), in accordance to the legalrequirements of Decree-Law no. 5/2011 – Environmental Licensing, andrespective regulations. The TOR is to be the guideline for the proponent tofollowandcarryouttheEIA.

2. What are we proposing?

TheGovernmentofTimor-Leste, throughtheDíliMunicipalAuthority (DMA),under the Ministry of State Administration (MSA), proposes the TibarDumpsiteRehabilitationandUpgradingProject(TDRUP).

In summary, the Government wants to invest in design, construction worksandspecializedequipmenttorehabilitatethecurrentwastedisposalsiteandupgradeittoasanitarylandfilloperatedandmanagedtomoderninternationalstandards.

Why?ToenhancetheconditionsofthecurrentTibaropendumpsite,thathasnegativeeffectsonpublichealthandtheenvironmentofthesurroundingarea.Its rehabilitation is highly recommendable to improve the environmentalquality and the level of public health of the surrounding population and thegeneralpublichealth,safetyandenvironmentamenityofDili.

TheTDRUP ispartof theDili SolidWasteManagementProject (DSWMP),anInvestmentStrategythat theGovernmentofTimor-LestehasdevelopedwithADB since 2015, which is legally defined in the Government Resolution no.32/2016-DiliUrbanSolidWasteManagementInvestmentStrategy.

TheDSWMPhasgonethroughseveralstepssince itsbeginning in2014,withthepreparationofanInitialEnvironmentalExamination(IEE)forTibarLandfill,carried out in 2015, and now the more recent steps to guarantee theimplementationoftheDSWMPstrategywithsupportfromanADBTransactionAdvisory(TA)Supportteam,composedoftheFinishingConsultingGroup(FCG,REBELandOASISSustainableProjects,toassisttheDMAinthenecessaryDueDiligenceandcarryouttheTechnicalStudiesfortheeffectiveimplementationoftheDSWMP.

Now, theproject is at aphasewhere a tenderprocesshasbeenopened forContracters to bid for a Design-Build-Operate (DBO) Contract, meaning thattheywill improveonthecurrentConceptDesign,alsobasedontheresultsofthis EIA assessment and carry out the implementation and operation of theprojectonbehalfoftheDíliMunicipality,foraperiodof10years.

3. Why do we need the project?

The population of Dili has grown rapidly over the past decades, currentlyestimated at 345,620 people (Census 2015), which has led to a significantincreaseinthewastemassgeneratedbycitydwellers.

Theexistingwastecollectionsystemisnotenoughandsosolidwasteendsupinthebeachesanddrainagesystem,frequentlyleadingtoflooding.

Governmentisintheprocessofimplementinganappropriateandsustainableurban solid waste management system for the long-term, modernizing thecollectionfleetandrehabilitatingTibarDumpsiteforsafedepositingofurbansolid waste, while waiting for recycling to establish itself and becomecommerciallyfeasibleinDili.

However,today,TibarDumpsiteisanopendumpwithair(wasteburning)andwaterpollution (leachate)andhealth risksassociatedwithwastepickersandinsectsandanimalpestsintheoperationalarea.

Togetherwiththewastecollectionimprovement,itwillalsohavetheindirectpositive impact of improving the quality of life and urban amenity of thepopulationofthecityofDili.

4. Why an Environmental Impact Assessment of the TDRUP?

This TDRUP Project requires Government environmental licensing andapproval under Timorese Law, where it has been classified as a Category A(Environmental Impact Assessment) [EIA] under Decree-Law no. 05/2011 –Environmental Licensing, because the dimension (area) of the proposed


Page 6 of 18

Landfill and the tonnage of waste received at the landfill (150 ton/day)surpassedthelimitssetinANNEXIotheDecree-Law,specificallyinitemno.1ofSECTORVII–SANITATIONSECTOR,oftheabove-mentionedDL(LandfillsanddisposalsofUrbanSolidWastes,<100Ton/day,1to100CBM/day,0.5to10hectares).

5. What is the EIA process

ItisalegalprocessgovernedbyTimoreseLawtoanalysetheimpactoflarge-scale projects proposed in Timor-Leste. EIA follows a process with thefollowingsteps:

Screening (Project Document): the first stage of the EIA process where theEnvironmental Regulator (National Environmental Licensing Authority [ANLA]ortheSecretaryofStateforEnvironment)decideifEIAisrequired.

Scoping (Terms of Reference): once it has been agreed that EIA is required,scoping is undertaken to define what to assess and report in theEnvironmentalImpactStatement(EIS)andaPublicConsultationiscarriedout,toearly identify issuesandthematicareasthatareexpectedtobeofgreaterrelevance,becauseofthepotentiallynegativeandpositiveenvironmentalandsocialimpactsgeneratedbyprojects.WEAREATTHISPHASE.

Baseline Assessment: With the scope set, relevant information on theenvironmentalbaselineconditionsiscollectedintheprojectareaandusedtounderstand thepotentialenvironmentaleffectsand informthedesignof theproposed development to minimise the potential for significant adverseimpacts.

ImpactAssessment:Theformalassessmentprocessisthenundertakenoftheproposed project to define the significant impacts of the proposeddevelopmentandaDraftEISisprepared.

Impact Management and Monitoring: Where significant adverse impactscannot be minimised through alterations to the design itself, mitigation orreduction measures are considered and put into an EnvironmentalManagement Plan (EMP), which also considers monitoring to measure thesignificance of the impact during and post-construction and allowmanagementofmitigationwhereappropriate.

DraftEIS/EMPtoEnvironmentalRegulator:OncetheEIAiscompleted,theEISand the EMP are submitted to the ANLA for review and another PublicConsultationiscarriedouttoreceivecommentsontheEIS/EMP.

6. Who is the Project Proponent?

The proponent of the project is theMunicipality of Díli, in the person of itsPresident,Mr.GasparSoares,supportedbyMs.EmilianaSoares,Director forthe Municipal Planning Agency, which can be contacted for any queriesrequiredbyinterestedparties,throughthefollowingcontact:

7. Who is the Assessment Team?

The Díli Municipality have requested and ADB have commissioned theenvironmental assessment to FCG-International and OASIS SustainableProjects, a local EnvironmentalConsultancyactive inTimor-Leste since2011,thathaspreparedtheenvironmentalapplicationandtheTORandisprovidingtechnicalinputs,environmentalassessmentandco-coordinatingtheEIAstudywith JGP NVIST, Consultoria Ambiental, S.A., a Portuguese consultancycompany.

8. What is our Project?

8.1. Where do we want to implement the Project?

6. CollectandTreattheproducedGas

Waste decomposition produces landfill gas (methane (40-60%) andcarbon dioxide (most of the rest), with trace amounts of othervolatileorganic compounds [VOCs]) thatneeds tobe collectedandtreatedforClimateChangeandLanfillSafetyissues.

A series of gas collectionwellswill be distributed throughout eachcell and installed as waste deposition proceeds in the cell.

9. How do we propose to assess the Environmental Impacts?

9.1. Collect information on the Project Site

TheEISwillprovideanoverviewanddetaileddescriptionofthenatureofthevariousimpacts(onphysical,biologicalandsocialcomponents)thatmayoccurduringtheimplementationofeachcomponentoftheTDRUPproject.

b) AirQuality:Collectairqualitysamplesat4points.c) Soil:Collectsoilsamplesat9points.d) Noise:Collectnoiselevelsamplesat6points(industrialandresidential).e) Social Components: Interview with the communities affected by the

f) Cultural Components: Field inspection by collecting the photos of theTibar archaeological, historic and sacred sites based on the CentroNacionalCHEGA(CNC)andSecretaryStateforCulture(SEC)data.

9.2. We will use that information to estimate impacts…

The assessment of the impacts of a project is the result of the comparisonbetween the foreseeable futureenvironmentalandsocial situationswith theprojectandinitsabsence(“ZeroAlternative”).

Wehavean ideaonthegeneral impactsattributedtoa landfill rehabilitationproject,suchastheonesintheTable1.

For this project, in order to identify and assess all relevant impacts, thecharacteristics of each environmental and social factor will be examined,followedbytheassessmentandpredictionoftheSIGNIFICANTimpactsbasedonadescriptionoftheireffectsandaqualitativecharacterisation.

9.3. How will we manage the significant impacts?

Wewill grab the significant impacts and definemitigationmeasures into anEnvironmentalManagementPlan(EMP)whichisthedocumentthat

It is tobecome the main obligation reference for contractors to follow during thedesign, construction and operation phases, and address the conditionsprecludedintheEMPthatwillbeattachedtotheBidandContractDocuments.

10. How can you participate in the next EIA phases?
