In
a
statement
late
on
Tuesday
Canadian
pipeline
operator
Enbridge
confirmed
an
estimated
1400
barrels
of
oil
were
released
on
Monday,
with
the
failure
of
a
flange
gasket
in
the
pumping
station
believed
to
be
the
cause
of
the
spill.
Enbridge
said
the
Athabasca
pipeline
was
shut
down
immediately
on
Monday
once
the
leak
at
the
pumping
station
was
detected.
It
added
the
spill
was
largely
contained
within
the
pumping
station
site
and
the
area
was
secured
and
clean-up
operations
began
immediately.
The
pipeline
was
restarted
later
on
Monday
and
was
running
normally…
