Summary:
Deputy Director Steve Lewis was notified by a DOI representative at
about 3 pm that an oil spill of unknown origin was moving toward Cape
Cod NS beaches. The spill size was estimated to be a half mile square.
At the time of initial report, there was reason to believe that the park
would sustain slight effects. The Coast Guard advised the park to
observe the spill and attempt to protect wildlife.

Follow-up call by Len Bobinchock, 9:20 am, 9/26: Bill Patterson of the
DOI Secretary's Office in Boston, who is responsible for hazardous
response coordination for the Department, has advised NPS that the slick
is actually dark brown, "almost black" seaweed. The mass was picked up
by a NOAA satellite on 9/25, and a NOAA office in Seattle reported it
to USCG in Boston, who in turn reported it to Patterson, who advised NPS.
No threat to park foreseen.

Summary: Dep. Dir. Steve Lewis notified @ approx. 1500hrs. this date by DOI
Representative in Boston that an oil spill of unknown origin was moving towards
CACO beaches. Spill size estimated to be 1 mile x 1 mile. At this time there
is reason to believe that the park will sustain slight effects. The U.S. Coast
Guard has advised the park to observe the spill (has yet to be sighted by park
observers on beach) and attempt to protect wildlife. At this time, due to the
unknown origin of the spill, any clean-up costs will be borne by the park.

Anticipated developments: Current state of wind/tide may dissipate the spill,
but this is uncertain. Park forced to adopt a "wait and see" position.
