PRO­VIDE SEC­ONDARY CON­TAIN­MENT AT ED­MON­TON TER­MI­NAL

Alberta Oil - - OIL SANDS REPORT -

Be­fore con­struc­tion can be­gin, Trans Moun­tain must sub­mit an up­dated risk as­sess­ment for po­ten­tial spills, boil-overs, flash fires and va­por cloud ex­plo­sions at its Ed­mon­ton Ter­mi­nal West Tank Area. The com­pany must demon­strate that its drainage sys­tem can quickly chan­nel a sig­nif­i­cant petroleum re­lease from any stor­age tank in its im­pound­ment lot to a re­mote im­pound­ment an­nex with­out over­flow—all while a one-in-100-year, 24-hour weather storm is oc­cur­ring. That sce­nario also has to in­clude drainage for stand­ing wa­ter gen­er­ated from fire­fight­ing ac­tiv­i­ties. Trans Moun­tain must show that its own mit­i­ga­tion mea­sures will re­duce risks to peo­ple and the en­vi­ron­ment to As Low As Rea­son­ably Prac­ti­ca­ble (ALARP) and in com­pli­ance with the Ma­jor In­dus­trial Ac­ci­dents Coun­cil of Canada’s cri­te­ria for risk ac­cept­abil­ity. Iden­ti­cal con­di­tions ap­ply to the Trans Moun­tain ter­mi­nals at Burn­aby and Su­mas, Bri­tish Columbia.
