Telephone

Called
to
inquire
about
barrier
nets
supplied
to
Chalk
Point
plus
general
cost
and
design
information.

The
twine
size
#
252
is
a
braided
nylon
netting
with
a
75
lb
test
strength.
The
net
specs
were
5/
8
inch
polydac
(
combination
polypropylene
&
dacron)
rope
at
top
with
floats
and
3/
16
inch
galvanized
chain
at
the
bottom.

The
costs
for
the
nets
requested
by
Chalk
Point
($
3,936
and
$
4,141)
include
tax
but
not
shipping.
He
estimated
shipping
will
add
approximately
12%
to
the
cost.
I
asked
about
how
net
costs
varied
with
depth.
He
said
a
comparable
300
ft
by
10
ft
net
would
cost
about
$
1,350.
He
said
that
net
manufacturing
is
very
labor
intensive
and
that
it
costs
more
if
the
net
requested
is
not
a
standard
width.
Shallower
nets
can
use
leadline
instead
of
chain
which
is
cheaper.

They
also
provide
fish
exclusion
netting
for
the
TVA
for
nuclear
facilities.
They
specify
a
different
"
delta"
netting
(
which
has
a
different
mesh
shape)
with
44
lb
test
twine.
He
was
not
sure
if
this
was
for
cooling
water
intakes.
They
do
not
install
and
only
provide
the
netting.

I
asked
about
anchors,
he
said
that
the
chain
or
leadline
in
most
cases
should
be
sufficient
depending
on
local
conditions.
