Special Considerations
K-69-01 Anton Larsen Bay
Nearshore waters in thegeneral area of:
Lat. 57º52.08'NLon. 152º37.77'W
Free-oil Recovery
Maximize free-oil recoveryin the offshore & nearshoreenvironment of AntonLarsen Bay depending onspill location and trajectory.
Deploy free-oil recovery strike teamsupwind and up current of Anton LarsenBay.
Use aerial surveillance to locateincoming slicks.
Deploy multiple free-oilrecovery strike teams as requiredto maximize interception of oilbefore it impacts the sensitiveareas in Anton Larsen Bay.
Vessel Platform Via marinewaters
Chart 16594-1
Same as K-69-02 Vessel master should have localknowledge.
Use extreme caution, shoal watersand extensive commercial vesseltraffic.
K-69-02 Anton Larsen Bay
Lat. 57º52.94'NLon. 152º37.51'W
Divert and Collect
Divert oil to shore-sidecollection points determinedby spill source andtrajectory
Deploy anchors and boom with skiffs(class 6).
Place 6 x 300 ft. sections of protected-water boom in cascaded arrays at properangle to divert incoming oil to thecollection sites.
Set up collection sites and tendthroughout the tide.

Fish- intertidal spawning-salmon (May-Sept.),herring (April-May)
Birds-waterfowlconcentration, seabirdnesting
Marine mammals- seals,otters
Habitat- marsh, shelteredrocky shoreline, gravelbeaches
Human uses- Commercialfishing, recreation, sportfishing
Vessel master should have localknowledge.
Numerous cabins and homes inthe area may provide logisticalsupport and local knowledge.
Take appropriate measures asoutlined in the STAR Manual toprotect the beach at the shoresidecollection site.

K-69-03 Anton Larsen Bay Stream
Lat. 57º52.28'NLon. 152º40.28'W
Exclusion
Exclude oil from enteringthe western entrance toAnton Larsen Bay.
Use skiffs to position and anchor thearray.
Place 350 ft. of protected-water boom atan angle across the channel.
Tend throughout the tide.
DeploymentEquipment

K-69-04 Anton Larsen Bay Streams
Lat. 57º50.51'NLon. 152º37.62'W
Passive Recovery
Place passive recoveryacross the channels of thestreams in Anton LarsenBay.
Deploy snare line or sorbent boom andanchors by foot across the identifiedstream.
The area consists of 8 cuts in themarshy bank and one stream. Placesorbents across the cuts and the stream atthe high-tide mark. Each cut will requireapproximately 100 ft. of boom
Replace as necessary to maximize therecovery.
DeploymentEquipment
900 ft. snare line or sorbent boom36 ea. anchor stakes
