This plan is an outcome of a series of interactions, workshops and meetings conductedamongthestaffofTGTDCLaswellasinteragencyworkshopsandmeetingconductedduringthe process. It is risk based contingency plan based on the earthquake loss estimationrecently conducted. Once the loss maps and the targeted scenario is changed, somemodifications in terms of human resources, materials and cost needs modificationaccordingly.
1.2ObjectivesofthePlan

The direct users of this Earthquake contingency plan will be the managementpersonnelofTitasGasTransmission&DistributionCompanyLimited(TGTDCL)inorderto provide natural gas services to the people of Dhaka city during immediateresponse and early recovery phase after an earthquake. The plan also covers thepreparednessactionsbeforeearthquakeforeffectiveresponseafterwards.
In addition to TGTDCL, the others such as line Ministries, Departments, CityAuthorities, NGOs/ INGOs, electronic and paper Media, Community basedOrganizations (CBOs), Civil Society Organizations (CSOs), Academia; DevelopmentPartners will be the passive users of the plan as they will be providing supportservices forplan implementationwith regard toemergency services.Theultimatebeneficiarieswould be the communities at risk to bringnormalcywithin a fastestpossibletime.
1.5 PlanImplementationStrategiesbytheAgency
Thefollowingstrategiesaretobeadoptedinplanimplementation: Setting up a strong organizational framework to identify and assess
earthquake hazards, analyze vulnerability , assess risk and loss estimationwithregardstonaturalgassystem;
Plan&developmentof institutionalcapabilitiestotranslateearthquakeriskreductionintoPreparednessandResponsePlans;
Establish a consistent, participatory approach to the management ofearthquakeemergencyresponses;
Undertake training and education programs on all phases of DisasterManagementforalllevelstobuildthecapacityofprofessionals;
Develop a mechanism to improve the relationships with nongovernmentorganizations to address mitigation, preparedness, response and recoveryphaseeffectively;
Transferknowledgeandstateoftheartoftechnologiesnecessarytosupportinstitutionaloperationsandimplementoperationplans;
1.6 PlanLimitations
Followinglimitationsarenotedwhenthisplanisdrafted: This plan do not address all aspects of earthquake risk management (e.g.
longtermrecoveryplans) ThePlanassumesthatthelineagencieswillhaveMandatoryprovisionsand
nationalcapacity todealwithassigned tasks.Mandatoryprovisions for lineagencies, ministries, and local governments. District authorities can begranted through a gazette notification but Lines of authority need to befinalizedandcommunicatedtoalllevels.

Earthquake risk assessment of the water and sanitation system was carried out underearthquakehazard,vulnerabilityandriskassessmentcomponentofCDMPprojectistakenas the base for the Contingency planning purpose. The loss estimation depends on thevulnerability assessment of the system as well as the expected hazards.

2.1.1EarthquakesHazardinBangladesh
Thecombinationofhighdisastereventsaswellasincreasinghumanvulnerabilityresultingfromdemographicpressure,poverty, social inequality andcoupledwith theapprehendedclimate change indicate that Bangladesh is, currently, at high risk to large scale disasterswithconsequentimpactonshelter,food,healthandsurvival.Bangladeshisalsosusceptibletodamagingearthquakes. It isa fact thatduring therecentpastnomajorearthquakehasoccurred in Bangladesh orwithin its neighborhood but records indicates that during thepast few hundred years there have been several significant earthquakes recordedwithinBangladesh. Reliable historical data for seismic activity affecting Bangladesh is availableonlyforthelast450years(Guptaet.al.1986).
Recently developed earthquake catalogue for Bangladesh and surrounding areas(Sharfuddin, 2001) shows1200earthquakeswith amagnitude (Ms) of 4.0haveoccurredbetween1885and1995,withina200kmradiusofBangladesh.

2.1VulnerabilityAssessmentofDhakaGasSystem
Vulnerability isassessed fromthecharacteristicsofgaspipelineanddistribution facilitiesthat make them susceptible to the damaging effect of an earthquake. In gas system,vulnerability is identified from the pipe ductility type, distribution facility type, and soilliquefactionsusceptibilityonwhichthepipeandfacilitylieon. Fromthefieldsurvey,itisfound thatmostofdistribution facilitiesarenotpreparedwith theseismicdesign,properanchorage, andbackuppower system.Fromvulnerability assessment,naturalGasSystemconsistsofpipelines(NGP1/NGP2)andcompressorstations(NGC).Botharevulnerabletodamageduringearthquake.Failureofnaturalgassystemmaycauseanotherdisasteroffire.The vulnerability is assessed from the characteristics of pipeline joints and distributionfacilities that make them susceptible to the damaging effect of an earthquake. The gaspipeline is welded steel pipe, and the critical part is located at the joint. Based on theweldingprocess,gaspipelineisdividedintogasweldedjoint (NGP1)andarcweldedjoint(NGP2).Fromdataacquisition,itisidentifiedthatgaspipelinesinthe3citiesarewitharcweldedjoints.Systemvulnerabilityisidentifiedfromthepipetypeandcompressorstationlocation relation to the soil liquefaction susceptibility onwhich they lie on. Pipeline andcompressor stations located on higher liquefaction susceptibility soil is more vulnerablethanthoseonlowornoneliquefactionsusceptibility.

2.4InterrelationshipwithotherLifelinesandUtilities
Transportation and lifeline infrastructure include road network, bridge, gas (natural gas)network, electric network, telephone network, water supply network, and seweragenetwork.Typicallysuchlifelinesystemsareextendedspatiallyoverlargeareasandconsistofnumerousstructures;theyarerelatedtourbanlivesandfunctionsandarevulnerabletoearthquake. InDhaka,gasandwatersewerageconnectionsstilluseeithergalvanized iron(GI) or concrete pipes. During an earthquake these are likely to breakdown very easily.Electricalserviceisalsolikelytocollapseduringandafteranearthquake.
Themajor causesofpostearthquake fires includegas leaksdue to failureofpipesorgasappliances;problemsintheelectricaldistributionsystem;flammablematerials;overturningof candles, lamps, cooking ovens, etc. Narrow roads in old town, garments and othermanufacturingindustriesindenseresidentialareasofDhakaarelikelytocreateadditionalproblemsintheeventofanearthquake.

Risk The probability of harmful consequences, or expected losses(deaths,injuries,property,livelihoods,economicactivitydisruptedor environment damaged) resulting from interactions betweennaturalorhumaninducedhazardsandvulnerableconditions.
Conventionally risk is expressed by the notationRisk = Hazards x Vulnerability. Some disciplines also include theconceptof exposure to referparticularly to thephysicalaspectsofvulnerability.
Beyond expressing a possibility of physical harm, it is crucial torecognize that risksare inherentor canbe createdor existwithinsocialsystems.Itisimportanttoconsiderthesocialcontextsinwhichrisks occur and that people therefore do not necessarily share thesameperceptionsofriskandtheirunderlyingcauses.(Source:ISDR)
