Special Considerations

NCI-02-01 Ship Creek

Nearshore waters in thegeneral area of:

Lat. 61º 13.38 NLon. 149º 54.03 W

Located between theAnchorage Small Boat Dockand the North Star Terminal.

Features include exposedtidal mudflats with high tidesof 32'. Tidal mudflats extendapproximately 1/4 mile atlow tide.

Creek channel: averagedepth at mouth is 20'-25' athigh tide and 1'- to 2' at lowtide; well defined channelentrance; moderate currents.

Small Boat Launch facilityat the mouth of the creek.

Divert and Collect

Divert oil to shore-sidecollection points determinedby spill source and trajectory.

Prevent oil fromcontaminating Ship Creek.

Deflect oil from the mouth ofthe creek, using boom in acascaded fashion.

Prevent oil from reaching therailroad trestle using exclusionboom across the creek at thepowerpoles.

Nearshore Task Force torecover product on waters.Depths of about 76'.

Stage overpack drums or alined vehicle for temporarystorage of used sorbent.

Use drip cloth on stream bankwhere spent sorbents arepulled out to prevent furthercontamination.

Deploy 4 or 5 segments of 100'Inland River Boom in a cascadedfashion at the mouth of the creekto deflect the spill. This willrequire 8-12 25 lb. anchors.

In high-energy conditions (highwinds, currents) deploy boom andanchors 1 hour before and afterslack water to provide bestconditions to lock in anchors.

Deploy 50' sorbent boom using 225-lb anchors, upstream of theculvert at the small-boat harboraccess road.

Deploy 100' of directional boomat boat ramp using 2 25-lbanchors.

Change direction of cascadeand directional booms as thetide changes.

Stage skimmer to collect oil inboat ramp basin.

As the circumstances of theemergency allow, report anycultural resources foundduring operations to the FOSCHistoric Properties Specialist.

If site conditions requireclosing the area to publicaccess, then a plan will need tobe developed to reroute trafficfrom this section of the area.

Take care not to work or walkon oiled shoreline to avoiddriving oil into the soils.
