AEA-16-01 Kenezuroff Lagoon

Nearshore waters in thegeneral area of:

Lat. 55º15.84'NLon. 162º38.49'W

Free-oil Recovery

Maximize free-oil recovery inthe offshore & nearshoreenvironment of KenezuroffLagoon depending on spilllocation and trajectory.

Deploy free-oil recovery striketeams upwind and up current ofKenezuroff Lagoon.

Use aerial surveillance to locateincoming slicks.

Deploy multiple free-oil recoverystrike teams as required to maximizeinterception of oil before it impactssensitive areas.

Vessel platform Via marinewaters

Same as AEA-16-02 Vessel master should havelocal knowledge.

Use extreme caution, shoalwaters with numerous reefsand rocks.

Exclusion

Exclude oil from impactingthe identified streams inKenezuroff Lagoon.

Deploy using helicopter due toextremely shallow waters.

Place and anchor protected-waterboom across each stream mouth.For (a&b) use and anchor systemto secure.

AEA-16-03 Kenezuroff Lagoon

Nearshore waters in thegeneral area of:

Lat. 55º18.08'NLon. 162º38.96'W

Wildlife Hazing

Under the direction of wildlifemanagers, use hazingtechniques to drive waterfowlaway from incoming oil.

Access the area via the ATV trailsystem.

Use hazing equipment as directedby wildlife managers to drivewaterfowl away.

Maintain hazing techniques untilthe oil is immobilized or removedfrom the area.

Tend throughout the tide.
