Special Considerations

PWSSW07-01

Pleiades Island

Nearshore waters in thegeneral area of:

Lat. 60º 13.92 NLon. 148º 00.77 W

Nearshore Free-oilRecovery

Maximize free-oil recovery inthe offshore & nearshoreenvironment of Pleiades Islanddepending on spill locationand trajectory.

Deploy nearshore free-oil recovery striketeams upwind and up current of PleiadesIsland.

Use aerial surveillance to locate incomingslicks.

Deploy multiple nearshore free-oilrecovery strike teams as required tomaximize interception of oil before itimpacts sensitive areas.

Same as PWS-SW07-02

Vessel master should have localknowledge.

Numerous submerged rocks

Deployment location isdependent upon spill trajectoryand weather.

Deploying FO-O with gate maybe difficult because ofmaneuvering room.

Surveyed, verified anddeployed: SERVS June 2001

PWSSW07-02

Pleiades Island

Actual location of thisprotection strategy willdepend on field assessment atthe time of deployment.

Passive Recovery-Marine Access

Minimize impact to marinemammal haulouts, afterconsulting with NMFS.

Transport equipment by vessel (class 3/4)from Seward.

Broadcast sorbent material on hauloutimmediately prior to or after oil spillimpact.

Monitor after each high tide and replaceas necessary.

Minimize disturbance of marinemammals.

Human use-subsistence, highrecreational use

Use snare boom for persistentoils and sorbent boom for non-persistent oils.

REPORT any cultural resourcesfound during operations toFOSC Historic PropertiesSpecialist.

Consult with the NationalMarine Fisheries Service priorto implementing this tactic.
