A = Acceptable
C = Conditional - Use after other less intrusive methods or following
particularly heavy impact
x = Not Advisable or Not Applicable
a = Manual removal of oiled debris or small persistent pockets.
b = Passive collection and vacuum should be coordinated with flooding
or washing methods.
c = Shoreline removal/replacement with clay if substrate is saturate
with oil.
d = Low intensity removal of mobile debris only - e.g. vegetation
or driftwood.
e = Trenching only if heavy impact exists and no other viable collection
method is available.
f = Proximity to water intakes should be considered when pressure
washing shoreline.
g = Consider biological community and porosity of substrate when
using pressure or elevated temperature.
h = No action only if residual sheening is present.
j = Hot water pressure wash or slurry sand blast for aesthetic
reasons.
k = Passive collection only if viscosity is low enough to result
in sorbent effectiveness.
