From

I
don't
know
if
any
state
in
R6
has
ever
required
entrainment
monitoring
in
the
permit
for
existing
facilities.
But,
a
new
facility
in
LA
used
entrainment
rate,
instead
of
entrainment
survival
rate,
in
its
demonstration
study.
I
interpreted
it
as
a
0%
survival.

Help
needed
­­­
From
Deborah
Nagle
I
need
some
help
from
the
field,
concerning
entrainment
survival.
We
have
been
reviewing
and
critiqueing
multiple
entrainment
survival
studies
for
the
316(
b)
Phase
II
NODA.
It
is
very
important
for
us
to
know
if
States
consider
entrainment
survival
when
making
316(
b)
determinations.
For
each
State
in
your
Region,
I
need
you
to
apply
one
of
the
answers
below:

ANSWERS
1.
Does
not
consider
entrainment
survival
at
all
2.
Assumes
entrainment
survival
is
0%
(
100%
mortality)
3.
Assumes
entrainment
survival
is
X%
(
fill
in
the
number
for
X)

I
need
this
information
quickly­­
this
week
if
possible.
Send
partial
information
instead
of
waiting
until
you
have
information
for
all
your
states.
Thanks
for
your
help.
