MEMORANDUM
DATE:
February

2002
TO:
316b
Administrative
Record
FROM:
John
Sunda,
SAIC
RE:
Data
Obtained
from
Power
Plant
Facilities
Concerning
Fish
Barrier
Net
Design
and
Cost.

SAIC
identified
power
plant
facilities
that
indicated
they
utilized
fish
barrier
nets
and
requested
barrier
net
system
design
and
capital
and
O&
M
cost
data
from
them
This
memo
summarizes
the
results
of
this
effort.

SAIC
began
the
cost
research
by
identifying
facilities
which
had
indicated
in
their
DQ
or
STQ
questionnaire
responses
that
they
used
fish
barrier
net
systems.
We
identified
seven
such
facilities:

Bethlehem
Steel
­
Sparrows
Point
Consumers
Energy
Co.
­
J.
R.
Whiting
Plant
Entergy
Arkansas,
Inc.
­
Arkansas
Nuclear
One
Exelon
Corp.
(
formerly
Commonwealth
Edison)
­
LaSalle
County
Station
Minnesota
Power
­
Laskin
Energy
Center
Potomac
Electric
Power
Co.
­
Chalk
Point
Southern
Energy
­
Bowline
Generating
Station
We
contacted
facility
representatives
for
these
seven
facilities.
All
of
the
facility
representatives
were
cooperative,
and
said
they
would
be
happy
to
help
us.
We
e­
mailed
all
seven
facilities
a
list
of
questions
regarding
flow,
net
size,
mesh
size,
cost,
etc
(
see
attached
completed
copies).
SAIC
received
responses
from
only
three
of
these
facilities:
Entergy
Arkansas,
Inc.
­
Arkansas
Nuclear
One,
Minnesota
Power
­
Laskin
Energy
Center,
Potomac
Electric
Power
Co.
­
Chalk
Point.
Copies
of
their
responses
to
our
questions
are
attached
to
this
memorandum.
We
attempted
to
follow
up
with
the
other
four
facilities,
but
no
responses
were
received.
Contact
Reports
documenting
our
telephone
contacts
with
these
facilities
are
also
attached
to
this
memorandum.

Concurrently,
SAIC
identified
potential
vendors
(
manufacturers
and/
or
installers)
of
fish
barrier
net
systems
through
Internet
research
and
through
our
contacts
with
the
above
facilities.
Initial
contacts
with
the
vendors
indicated
that
before
they
could
develop
cost
estimates,
they
would
need
information
on
the
dimensions
and
configurations
of
the
intakes.
SAIC
also
contacted
the
Chalk
Point
facility
to
obtain
more
information
concerning
the
design
and
operation
of
the
fish
barrier
net.
SAIC
used
the
information
collected
from
the
survey
facilities
and
previous
EPA
research
to
develop
several
"
typical"
configurations
for
fish
barrier
nets,
and
to
correlate
intake
flow
and
net
size.
SAIC
was
unable
to
identify
specific
guidelines
or
design
criteria
for
fish
barrier
nets.
Rather
it
seemed
that
each
facility
selected
net
materials
and
specifications
based
on
their
sitespecific
conditions.
Therefore,
the
cost
estimates
relied
heavily
on
data
from
the
survey
facilities
and
additional
follow­
up
data
from
vendors.

The
following
is
a
list
of
telephone
contact
reports
that
provided
additional
cost
and
net
design
data:

13.
How
is
the
barrier
net
situated/
installed
around
the
intake
structure?

The
1st
net
section
is
anchored
on
shore
and
fed
out
into
the
water
using
a
pontoon
boat.
The
2nd
section
is
then
spliced
to
the
1st
section
and
the
process
is
continued
to
the
3rd
section
which
is
then
spliced
to
the
2nd
section.
The
3rd
section
is
then
anchored
to
shore.
The
net
forms
a
semi­
circular
barrier
in
front
of
the
intake
structure
(
approx.
100­
150
feet
from
the
intake
out
to
the
apex
of
the
circle).
Anchors
and
buoys
are
also
used
at
regular
intervals
to
secure
the
entire
installation
in
place
and
to
warn
the
water­
using
public.
The
net
is
installed
each
spring
in
May
and
then
removed
in
October
for
winter
storage.

14.
What
type
of
maintenance
activities
does
the
barrier
net
require?

Repositioning
if
wave
action
causes
the
net
to
shift,
or
buoy
maintenance
to
keep
the
net
afloat
are
usually
the
two
key
issues.
Some
mending
may
also
need
to
occur
to
damage
that
may
be
caused
by
installation
or
time.
There
is
also
some
maintenance
needed
on
the
signage
that
is
posted.

15.
What
is
the
average
annual
maintenance
cost
for
the
barrier
net?

$
1000
16.
Is
the
barrier
net
in
place
year
round,
or
just
seasonally?
If
seasonal,
when?

Seasonal.
It
is
put
out
when
the
ice
is
out
and
taken
in
just
before
the
ice
forms.

I
had
called
because
the
answers
he
sent
did
not
fully
answer
what
the
dimensions
of
the
intake
were.
He
left
