Questions
for
the
Committee

Are
there
characteristics
of
mega
sites
that
indicate
the
need
for
a
unique
or
supplemental
decision
process
for
NPL
listing?
Are
there
alternatives
to
placing
mega
sites
on
the
NPL?

Are
there
better
ways
of
managing
mega
site
cleanup
costs
under
Superfund?

What
other
options
for
cleanup
of
mega
sites
exist
in
Federal,
State
or
other
programs?

Are
there
more
meaningful
/
appropriate
descriptors
(
other
than
"
cost")
that
can
help
us
better
analyze
cleanup
program
or
resource
management
options?
