Review

High
Design
Flow
Phase
III
Facilities
(>
250

for
Hydropower
Water
Use
and
Confirmation
That

Greater
Than
25%

This
memo
documents
verification
of
in­
scope
status
of
Phase
III
facilities
with
design
flows
greater
than
250
MGD
or
greater.
Technical
surveys
regarding
flow
and
cooling
water
components
along
with
the
flow
schematics
were
reviewed.
In
reviewing
the
25%
cooling
water
criterion,
if
the
aggregate
response
to
Q3(
h)
was
<
25%,
the
average
intake
flow
Q25
was
reviewed
to
determine
if
underutilized
intake
capacity
was
consistent
with
the
reported
total
flows
and
design
flows.
In
summary,
four
facilities
use
the
majority
of
their
intake
water
for
hydropower.
These
four
facilities
do
not
meet
the
25%
water
use
for
cooling
purposes
criterion,
and
are
therefore
considered
out
of
scope.
