Peter,

As
best
we
can
determine,
the
evaluation
of
316(
b)
demonstrations
in
Ohio
for
existing
power
plants
assumed
100
percent
mortality
for
all
fish
eggs
and
larvae
unless
a
site­
specific
study
demonstrated
that
some
other
mortality
rate
was
more
appropriate.

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.
