The
notice
cited
“multiple
permit
violations”
by
the
ice
class
drilling
unit
Kulluk
and
the
drillship
Noble
Discoverer.
Shell
could
be
subject
to
fines
or
other
measures,
as
a
consequence
of
violating
the
Clean
Air
Act.
The
EPA
said
the
problems
were
found
during
an
inspection
of
the
Noble
Discoverer
and
because
Shell
reported
it
had
exceeded
nitrogen
oxide
emissions
limits
on
both
its
rigs
during
operations
last
summer.
The
Kulluk
was
operating
in
the
Chukchi
Sea,
while
the
Noble
Discoverer
was
in
the
Beaufort.
Shell
knew
the
strict
emissions
standards
could
be
a
problem…
