Special Considerations

AEB-02-01 Surf Bay/Lost Harbor

Nearshore waters in thegeneral area of:

Lat. 54º 11.1 NLon. 165º40.0 W

Free-oil Recovery

Maximize free-oil recovery inthe offshore & nearshoreenvironment of Surf Bay/LostHarbor depending on spilllocation and trajectory.

Deploy free-oil recovery striketeams upwind and up current ofSurf Bay/Lost Harbor.

Use aerial surveillance to locateincoming slicks.

Deploy multiple free-oilrecovery strike teams as requiredto maximize interception of oilbefore it impacts sensitive areas.

Akutan Harbor. Via marinewaters

Use extreme caution, shoalwaters with numerous reefsand rocks.

Exclusion

Exclude oil from impacting theidentified stream and intertidalarea in Surf Bay.

Deploy anchors and boom withskiffs (class 6) at high tide.

Place 100 ft. of tidal-seal boomacross each stream mouth on thebeach.

Tend throughout the tide.

Deflection

Deflect oil away from theseabird nesting and seal haul-outs in Surf Bay and away fromthe shoreline in Lost Harbor tofree-oil recovery.

Deploy boom and anchor systemwith skiffs (class 6).

Place booms in arrays (a)&(b) inchevron patterns. Array (c)&(d)should be cascaded from shore.

Tend throughout the tide.
