GENERAL INFORMATION Survey Date: Area: Location: Segment: _ 6 RESPONSE GOALS SE G M ENT PR O T ECTI O N O B JE CTIVES : S H O RE L I N E CLEANU P / T REAT M ENT O B J E CT I V ES: Prevent contact with shore or resource(s) at risk Allow natural recovery Minimize contact Restore shore to pre-oiling condition Prevent oil movement to adjacent segment(s) Accelerate natural recovery Contain stranded oil Restore with minimal removal of material Prevent oil transport into inlet, estuary, or Minimize oil remobilization channel Minimize damage to dune, marsh, or peat bog Other: Other: SEG M ENT PRO TECTIO N STRATEG IES:

Contain/recover oil on water SHO RELINE CLEANUP / TREATM ENT STRATEG IES: Alter direction of movement of oil on water Monitor Prevent oil movement (landward) on flooding Act quickly to remove stranded oil before burial tides Remove bulk oil only Trap/contain and collect oil at the shoreline Minimize waste generation using in-situ treatment methods Prevent remobilization of stranded oil Manual techniques preferred Prevent overwash into the backshore or a lagoon Salt-marsh fringe/meadow treatment strategies Pre-impact shoreline debris removal Man-made backshore riprap treatment techniques Other: Other:
