Subject:
Preliminary
Assessment
of
Impingement
and
Entrainment
Losses
at
JP
Pulliam
Power
Plant,
1975­
1976.

This
memorandum
describes
impingement
and
entrainment
losses
at
JP
Pulliam
Power
Plant
(
April
1975­
March
1976)
expressed
as
of
age
1
equivalent
losses.
The
original
data
source
is
Nalco
(
1976).

The
age
1
equivalency
analysis
uses
species
specific
life
history
parameters
that
were
previously
assembled
for
use
in
the
case
study
assessment
of
the
Monroe
facility.
The
analysis
uses
the
same
methods
and
simplifying
assumptions
that
were
use
in
the
316(
b)
case
studies.

An
assumption
that
may
be
particularly
important
for
the
Pulliam
analysis
pertains
to
the
age
of
impinged
fish.
Impinged
fish
were
assumed
to
be
age
1.
The
reported
age
1
equivalents
are
underestimate
the
correct
value
to
a
degree
proportional
to
the
fraction
of
impinged
fish
that
were
older
than
age
1.
Nalco
(
1976)
does
not
report
that
age
of
impinged
fish.
However,
they
do
report
the
mean
length
and
weight
of
impinged
fish,
and
they
provide
graphical
displays
of
length
frequencies
for
the
most
abundant
species.
Those
data
indicate
that
a
substantial
number
of
impinged
fish
may
have
older
than
one
year.

Several
species
were
aggregated
into
generalized
species
groupings
similar
to
those
used
for
Monroe
in
order
to
make
use
of
readily
available
life
history
parameters,
or
to
accommodate
variations
in
the
taxonomic
precision
used
in
the
original
data
records.
The
effect
of
species
aggregation
is
probably
negligible.

The
original
loss
records
are
provided
as
Table
1,
and
corresponding
age
1
equivalent
values
are
provided
as
Table
2.
Notes
in
these
tables
indicate
which
species
have
not
been
assessed
at
this
point
due
to
lack
of
readily
available
life
history
parameters.
These
missing
values
could
be
determined
with
further
data
assembly
if
required.
Species
that
were
not
addressed
seem
to
be
generally
small
portions
of
the
total
