These times do not include travel time from base to spill site, which may have multiple components (see Tactic L-3).EQUIPMENT AND PERSONNELEQUIPMENTBASELOCATIONFUNCTIONPIECES# STAFFPER SHIFTMOBETIMEDEPLOYTIMECATWide-Track DozerorWide-Track Dozer All Snow bermconstructionFront-End Loader All Snow bermconstruction1 1 1 hr 0.5 hr1 1 1 hr 0.5 hrGravel PadorBobcatACS, EOA, KRU,AlpineAs needed 1 1 1 hr 0.5 hrTOTAL STAFF 1LoaderBobcatTundraSUPPORTHeavily OiledSnow BermLightly OiledEQUIPMENTBASELOCATIONFUNCTIONSemi and Trailer GPB, KRU, Alpine Transport wide-trackdozerPIECES# STAFFPER SHIFTMOBETIMEDEPLOYTIME1 1 driver 1 hr 0Heaters All Heat >1 1 (initial) 1 hr 0.5 hrFuel Truck All Fuel heavy equipment 1 Once per shift 1 hr 0.5 hrMechanic Support All Support equipment 1 1 1 hr 0.5 hrLake IceLube Truck All Provide fluids to heavyequipment1 Once per shift 1 hr 0.5 hrLight Plant All Illumination >1 2 for initial set-up,and 1 to check andfuel occasionally.1 hr 0.5 hrA snow berm is built around the areas of heaviest oiling to contain oil or diesel spilled to tundra and/or ice inwinter. A rubber tracked, wide-track dozer drives around the spill with its blade angled towards the spill, pushingsnow into a berm. Once the perimeter has been covered with an initial berm, the dozer shores up areas,as necessary.A front-end loader could also be used to build a berm, and a Bobcat can be used to access areas the largefront-end loader or wide-track dozer cannot reach.CAPACITIES FOR PLANNING• A wide-track dozer can build an initial snow berm around the largest tank spill within an hour. Any shoring wouldtake 3 hours or less.• Normally, a front-end loader can build a snow berm on a pad within 1 hour.DEPLOYMENT CONSIDERATIONS AND LIMITATIONS• The wide-track dozer is the most efficient piece of equipment in snow berm construction, and can access tundraand ice-covered lakes. If insufficient snow cover exists, front-end loaders would provide snow for the wide-trackdozer.• When working with equipment around or near flowlines, add a spotter to each front-end loader and wide-trackdozer.• When ice-reinforced, snow berms are useful to contain oil that melts out during breakup.• A civil work permit from the operator is required for all work on owner-company pads.ACS Tech.
