Costs
TOPICS
DISCUSSED
AND
ACTION
TAKEN
I
called
Tim
Connor
to
discuss
the
costing
activities
under
316(
b)
to
determine
if
there
is
any
information
that
can
be
used
in
the
steam
electric
detailed
study.
The
major
points
discussed
are
listed
below:

$
The
316(
b)
survey
did
not
contain
a
lot
of
information
on
the
configuration
of
the
intake
structure
which
increased
the
difficulty
in
costing
technologies.
For
example,
the
number
and
size
of
pumps
were
not
requested.
The
survey
did
contain
information
on
the
water
body.

$
The
316(
b)
rule
focused
on
reducing
fish
kills
and
therefore
focused
on
reducing
impingement
by
technologies
such
as
screening.

$
The
facilities
and
UWAG
did
not
agree
with
EPA's
cost
analysis
for
cooling
towers.
DOE
developed
their
own
costs
for
the
industry
which
were
much
higher
than
EPA's.
EPA
cost
information
was
based
on
data
from
retrofitting
three
facilities.
UWAG
argued
that
retrofitting
is
usually
not
possible
and
that
these
were
unusual
cases.
If
facilities
could
retrofit
cooling
towers
they
would
already
be
doing
that.

$
One
alternative
to
cooling
towers
that
was
investigated
was
converting
from
constant
speed
to
variable
speed
pumps.
This
would
allow
plants
to
cut
back
on
flow
during
non­
peak
months.
However,
this
only
reduces
flow
by
about
10%
versus
a
90%
reduction
when
converting
to
a
recirculation
system.

$
New
facilities
­
Most
new
plants
are
large
facilities
and
therefore
would
use
a
recirculating
system.

$
Existing
facilities
­
Tim
estimated
that
30­
40%
of
existing
facilities
used
a
recirculating
system.
The
facilities
that
are
once­
through
systems
are
generally
the
older
facilities.
These
facilities
are
generally
coal,
oil,
or
nuclear.
A
few
of
the
older
plants
have
done
studies
to
look
at
converting
to
a
recirculation
system
but
the
costs
are
prohibitively
high.
The
Diablo
Canyon
plant
in
California
estimated
in
would
cost
$
800
million
to
retrofit
their
plant.
