Screen
Meeting
Notes
Dear
Mark:

Thank
you
again
for
coming
to
EPA
and
sharing
information
related
to
your
Z­
Alloy
technology.
Please
see
the
attached
draft
meeting
notes
for
your
comments.
Please
send
me
your
comments
within
the
next
two
weeks.

Regarding
your
question
below,
we
would
like
to
have
as
much
information
submitted
before
the
June
25th
deadline
as
possible.
We
can
and
will
use
information
received
after
the
deadline.
In
particular,
we
are
interested
in
know
more
about
the
specifics
of
the
Z­
Alloy
deployments
(
Industry,
Location,
Month/
Year
of
Installation,
Type
of
Water
(
fresh,
estuarine,
marine),
MGD,
Air
Scour
(
Y/
N),
Designed
Through­
Screen
Velocity,
Functioning
Properly
(
Y/
N),
etc.).

I
have
compiled
a
quick
list
from
our
older
installations.
It
has
several
CuNi
screen
users,
but
should
not
be
considered
a
complete
list.
As
I
mentioned
in
our
meeting,
we
are
in
the
process
of
consolidating
all
of
our
installation
lists
and
contacts
for
these
types
of
screens.
This
list
will
not
be
completed
by
the
June
25th
but
hopefully
the
short
list
of
what
appears
to
be
seawater
intakes
will
be
of
some
use.
As
far
as
I
know,
these
screens
have
been
functioning
properly.
Most
of
the
screens
we
supply
do
have
an
integral
air
scour
pipe.
Designed
screen
velocity
has
always
been
.5
fps
max
unless
otherwise
requested
by
our
customers.

Install
List.

We
are
also
interested
if
you
or
any
one
you
know
has
designed
a
intake
structure
for
an
coastal
or
offshore
oil/
gas
extraction
facility.

The
last
one
on
the
list,
Texaco
Harvest,
appears
to
be
an
offshore
oil/
gas
installation.
I
do
not
currently
have
any
additional
information
on
this
installation
but
I
will
try
and
complete
the
contact
details.

What
would
be
the
material
costs,
time
of
installation,
and
any
O&
M
costs
for
a
Z­
Alloy
screen
deployment
for
such
an
operation.

Typical
lead
time
is
2
weeks
for
drawing
submittal,
4­
8+
weeks
for
intake
manufacture
depending
on
the
size
of
the
screen.
The
costs
will
depend
on
capacity,
depth
and
slot
(
screen
opening
size)
but
for
example:

Johnson
SWS
Intake
Model
T33
63
wire
with
0.039
circumferencial
slot
Installation
at
10

Velocities
(

.396
Avg
End
Fittings:
plate
one
end,

other
end.
Connected

24PS
inlet
pipe
Material:
ZAL
Estimated
net
wt:
1074
Lbs
Budget
Price:
$
16,780
each
($
US)
This
example
is
for
an
arbitrary
5
MGD
capacity
screen.
I
can
quickly
work
up
pricing
on
any
specific
flow
values
that
are
required.
Please
not
that
this
is
an
order
of
magnitude
price,
and
would
be
adjusted
for
current
material
costs
at
the
time
of
bid.
