facility's
premises.
Cooling
water
that
is
used
in
a
manufacturing
process
either
before
or
after
it
is
used
for
cooling
is
considered
process
water
for
the
purposes
of
calculating
the

flow
that
is
used
for
cooling
purposes
in
§
125.91(
c).
Diel
means
sample
variation
in
organismal
abundance
and
density
over
a
24­
hour
period
due
to
the
influence
of
water
movement
and
changes
in
light
intensity.
Director
means
the
same
as
defined
in
40
CFR
122.2.
Existing
facility
means
any
facility
that
commenced
construction
before
January
17,
2002;
and
(

Any
modification
of
such
a
facility;
(
2)
Any
addition
of
a
unit
at
such
a
facility
for
purposes
of
the
same
industrial
operation;
(
3)
Any
addition
of
a
unit
at
such
a
facility
for
purposes
of
a
different
industrial
operation,
if
the
additional
unit
uses
an
existing
cooling
water
intake
structure
and
the
design
capacity
of
the
intake
structure
is
not
increased;
or
(
4)
Any
facility
constructed
in
place
of
such
a
facility,
if
the
newly
constructed
facility
uses
an
existing
cooling
water
intake
structure
whose
design
intake
flow
is
not
increased
to
accommodate
the
intake
of
additional
cooling
water.
Once­
through
cooling
water
system
means
a
system
designed
to
withdraw
water
from
a
natural
or
other
water
source,
use
it
at
the
facility
to
support
contact
and/
or
noncontact
cooling
uses,
and
then
discharge
it
to
a
water
body
without
recirculation.
Once­
through
cooling
systems
sometimes
employ
canals/
channels,
ponds,
or
nonrecirculating

shellfish
by
60
to
90
percent
from
the
calculation
baseline
if
your
facility
has
a
capacity
utilization
rate
of
15
percent
or
greater
and
withdraws
cooling
water
from
a
tidal

costly
design
and
construction
technologies,
operational
measures,
and/
or
restoration
measures
to
the
extent
justified
by
the
significantly
greater
cost.
The
Director's
site­
specific
determination
may
conclude
that
design
and
construction
technologies,
operational
measures,
and/
or
restoration
measures
in
addition
to
those
already
in
place
are
not
justified
because
of
significantly
greater
costs.
(

The
plan
must
contain
the
following
information:
(
i)
A
narrative
description
of
the

and
operation
of
all
design
and
construction
technologies
or
operational
measures
(
existing
and
proposed),
including
fish
handling

the
requirements
to
reduce
entrainment
of
those
species
expected
to
be
the
most
susceptible
to
entrainment,
if
applicable,
and
information
that
demonstrates
the
efficacy
of
the
technology
for
those
species;
(
iii)
Calculations
of
the
reduction
in
impingement
mortality
and
entrainment
of
all
life
stages
of
fish
and
shellfish
that
would
be
achieved
by
the

selected
based
on
the
Impingement
Mortality
and
Entrainment
Characterization
Study
in
paragraph
(
b)(
3)
of
this
section.
In
determining
compliance
with
any
requirements
to
reduce

you
must
assess
the
total
reduction
in
impingement
mortality
and
entrainment
against
the
calculations
baseline
determined
in
paragraph
(
b)(
3)
of
this
section.
Reductions

from
this
calculation
baseline
as
a
result
of
any
design
and
construction
technologies

operational
measures
already
implemented
at
your
facility
should
be
added
to
the
reductions
expected
to
be
achieved
by
any
additional
design
and
construction
technologies
and
operational
measures
that
will
be
implemented,
and
any
increases
in
fish
and
shellfish
within
the
waterbody
attributable
to
your
restoration
measures.
Facilities
that
recirculate
a
portion
of
their
flow
may
take
into
account
the
reduction
in
impingement
mortality
and
entrainment
associated
with
the
reduction
in
flow
when
determining
the
net
reduction
associated
with
existing
technology
and
operational
measures.
This
estimate
must
include
a
site­
specific
evaluation
of
the
suitability
of
the
technology(
ies)
based
on
the
species
that
are
found
at
the
site,
and/
or
operational
measures
and
may
be
determined
based
on
representative
studies
(
i.
e.,
studies
that
have
been
conducted
at
cooling
water
intake
structures
located
in
the
same
waterbody
type
with
similar
biological
characteristics)
and/
or
site­

technologies
or
operational
measures
that
you
have
selected
(
i.
e.,
the
benefits
you

or
restoration
measures
will
maintain
fish
and
shellfish
at
a
level
comparable
to
that
which
would
be

to
serve
as
spawning
or
nursery
areas
or
establishment
of
riparian
buffers
will
achieve
comparable
performance,
you
may
make
a
qualitative
demonstration
that
such
measures
will
maintain
fish
and
shellfish
in
the
waterbody
at
a
level
substantially
similar
to
that
which
would
be
achieved
under
§
125.94;
(
iii)
A
plan
for
implementing
and
maintaining
the
efficacy
of
the
restoration
measures
you

with
the
implementation
of
the
technologies
in
the
permit.
In
considering
a
permit
application,
the
Director
must
review
the
performance
of
the
technologies
implemented
and
require
additional
or
different
design
and
construction
technologies,
if
needed,
to
meet
the
impingement
mortality
and
entrainment
reduction
requirements
for
all
life
stages
of
fish
and
shellfish.
In
addition,
you
may
consider
any
chemical,
water
quality,
and
other
anthropogenic
stresses
on
the
source
waterbody
in
order
to
determine
whether
more
stringent
conditions
are
needed
to
comply
with
the
requirements
of
other
applicable
Federal,
State,
or
Tribal
law
in
accordance
with
§
125.94(
e).
(
ii)
If
you
determine
that
restoration
measures
are
appropriate
at
the
Phase
II
existing
facility,
you
must
review
the
Information
to
Support
Proposed
Restoration
Measures
required
under
§
125.95(
b)(
5)
and
determine
whether
the
proposed
measures,
alone
or
in
combination
with
design
and
construction
technologies
and
operational
measures,
will
maintain
the
fish
and
shellfish
in
the
waterbody
at
a
comparable
level
to
that
which
would
be
achieved
under
§
125.94.
If
the
application
includes
a
qualitative
demonstration
for
restoration
measures
that
will
result
in
increases
in
fish
and
shellfish
that
are
difficult
to
quantify,
you
must
determine
whether
the
proposed
measures
will
maintain
fish
and
shellfish
in
the
waterbody
at
a
level
substantially
similar
to
that
which
would
be
achieved
under
§
125.94.
You
must
also
review
and
approve
the
proposed
Verification
Monitoring
Plan
submitted
under
§
125.95(
b)(
7)
and
require
that
the
monitoring
continue
for
a
sufficient
period
of
time
to
demonstrate
that
the
restoration
measures
meet
the
requirements
of
§
125.94(
d).
(
iii)
For
a
facility
that
requests
requirements
based
on
site­
specific
best
technology
available
for
minimizing
adverse
environmental
impact,
you
must
review
the
application
materials
and
any
other
information
you
may
have
that
would
be
relevant
to
a
determination
of
whether
alternative
requirements
are
appropriate
for
the
facility.
If
you
determine
that
alternative
requirements
are
appropriate,
you
must
make
a
site­
specific
determination
of
best
technology
available
for
minimizing
adverse
environmental
impact
in
accordance
with
§
125.95(
c).
(
2)
Monitoring
Conditions.
The
permit
must
require
the
permittee
to
perform
the
monitoring
required
in
§
125.96.
In
determining
applicable
monitoring
requirements,
the
Director
must
consider
the
facility's
verification
monitoring
plan,
as
appropriate.
You
may
modify
the
monitoring
program
when
the
permit
is
reissued
and
during
the
term
of
the
permit
based
on
changes
in
physical
or
biological
conditions
in
the
vicinity
of
the
cooling
water
intake
structure.
(
3)
Record
Keeping
and
Reporting.
At
a
minimum,
the
permit
must
require
the
permittee
to
report
and
keep
records
as
required
by
§
125.97.
