TACTIC C-19 Containment Light Layer of Oil on Snow using Snow Fence (Page 1 of 2) Containment Light Layer of Oil on Snow using Snow Fence (Page 2 of 2) TACTIC C-19NOTE: “Base Location” is storage location (may change seasonally); “Mobe Time” is time to get it out of storage, prepare it foroperation, and make it ready to travel (concurrent for all equipment); “Deploy Time” is time to make it operational for its intended useat the spill site. These times do not include travel time from base to spill site, which may have multiple components (see Tactic L-3).EQUIPMENT AND PERSONNELWINDEQUIPMENTBASELOCATIONFUNCTIONPIECESSnow Fencing ACS, KRU Containment VariesT-Post Driver ACS, KRU Support fence VariesT-Posts ACS, KRU Support fence VariesWire Ties ACS, KRU Support fence Varies# STAFFPER SHIFT*The number of staff to erect snow fencing depends on the size of the contaminated area.MOBETIMEDEPLOYTIME>2* 2 hr VariesSUPPORTEQUIPMENTSnow machine orATV with trailerBASELOCATIONFUNCTIONPIECES# STAFFPER SHIFTMOBETIMEDEPLOYTIMEAll Haul equipment Varies 2 0.5 hr VariesDEPLOYMENT CONSIDERATIONS AND LIMITATIONS• A temporary snow fence can be as long as needed to effect containment. The fence should be placed far enoughdownwind of the spill to collect drifting and migrating oiled snow. The fence should be at least 4 ft high, but can bemade up to 8 ft high by double-stacking ACS’ plastic 4-ft fence. The fencing itself should have at least 50% porosity.Tighten the fence as much as possible, and use T-posts, rebar, or survey lath for temporary fence posts.A snow fence can be erected on the downwind side of lightly oiled snow to keep the wind from spreading the contaminatedsnow before being recovered.• This tactic is based on information from Controlling Blowing and Drifting Snow with Snow Fences and Road Design.Prepared by Ronald D.

After a loader has filled a truck, the truck hauls the oiled snow off for disposal. A Bobcatwould replace the front-end loader in hard-to-reach or tight quarters.If nearby heavily oiled snow needs blending to ease recovery, then loaders and dozers may be used to push thelightly oiled snow into the heavily oiled snow area. Mixing the lightly oiled snow with the heavily oiled snow wouldgenerate less waste.EQUIPMENTBASELOCATIONEQUIPMENT AND PERSONNELFUNCTIONPIECES# STAFFPER SHIFT*Number of dump trucks depends on distance to disposal area.

Snowmelters can typically handle 30 cubic yd of lightlyoiled snow per hour.• A wide-track dozer can build an initial snow berm around the largest tank spill on the Slope within an hour.• A front-end loader with an 8-cubic-yd snow bucket can move 500 cubic yd of snow in an hour and fill a dumptruck in 10 minutes. See Tactic L-6, Table 9A, for capacities of dump trucks available on the North Slope.• Following is an example of recovery of lightly oiled snow for one 20-cubic-yd dump truck, with 2 miles betweenload and unload points:Dump Truck Recovery Rate =Where:T c = Truck CapacityT cL t + T t + U tL t = Load Time (10 min or 0.17 hr)U t = Unload Time (5 min or 0.08 hr)T t = Travel Time (miles to disposal * 2)35 mphThe ratio of dump trucks to loaders to fill truckswithout delay = 1 / (0.17 hr + 0.114 hr + 0.08 hr)= 1 / (0.364) = 2.7 trucks per loader.=20 cubic yd0.17 hr + 2 mi * 2( ) + = 55 cubic yd/hr0.08 hr35 mphOIL CONTENT (Percent)10080604020(or 16.5 bbl/hr)SNOW SORPTIVE CAPACITY(% by Volume after Sample Melt)PRUDHOE BAY CRUDE OILDIESEL OIL0 1 2 3 4 5 6TIME AFTER SPILL (Days)DEPLOYMENT CONSIDERATIONS AND LIMITATIONS• This tactic is limited to oiled snow with no free liquids. Collect the top 6 inches of snow into piles for recovery. Ifsnow cover is light or the snow will be used for blending, collect all of the snow.• When working with equipment around or near flowlines, add a spotter to each front-end loader or wide-track dozer.NOTE: “Base Location” is storage location (may change seasonally); “Mobe Time” is time to get it out of storage, prepare it foroperation, and make it ready to travel (concurrent for all equipment); “Deploy Time” is time to make it operational for its intended useat the spill site. These times do not include travel time from base to spill site, which may have multiple components (see Tactic L-3).• An ice road allows dump trucks into recovery sites on tundra.ACS Tech.
