Special Considerations
SE06-07-01 Dundas Bay
(confluence of NW andSW arms) at:
Lat. 58º 24.05 NLon. 136º 28.4 W
Free-oil Recovery
Maximize free-oil recovery innear the source of the spill.Note: The confluence is achoke point and poses thehighest risk of a grounding ofthe areas in Dundas Bay.
Deploy free-oil recovery strike teams inareas immediately adjacent to the vesselcasualty. Use aerial surveillance to locateareas of heavy slick concentrations.
Multiple free-oil recovery striketeams as required to maximizeinterception of oil before it impactssensitive areas.
Bartlett Cove,Glacier BayNational Park, orGustavus
Via marine waters. Marine mammals-harbor seals
Fish-intertidal salmon spawning(pink, chum) (summer-fall)
Birds-waterfowl and shorebirds(year-round)
Habitat-marsh, tidal mudflats andwetlands
Human use-high recreational use
Land management-National Park
Terrestrial mammals-bears
Bear hazard alongshoreline.

e. Lat. 58º 22.15 NLon. 136º 23.7 W
Exclusion
Exclude oil from enteringwetlands north of islets.
Use class 2 and class 3/4 vessels withdeck space to transport equipment. Placeprotected-water boom, with tidal-seal oneach end between islets using class 6skiffs. Boom should roughly follow theline of the channel.

Passive Recovery
Minimize impact to designatedarea through passive recoveryusing snare line or sorbentboom.
Place 500 ft. snare line or sorbent boomacross mudflats. Anchor with stakes.Replace oiled sections as needed.
Use snare line for persistent oils andsorbent boom for non-persistent.
