Introduction
This
memorandum
provides
a
list
of
errors
identified
by
Stratus
Consulting
in
the
April
2002
Case
Study
Document,
Economic
and
Benefits
Analysis
(
EBA),
and
Preamble
for
the
proposed
§
316(
b)
Phase
II
rule.
Where
appropriate,
we
indicate
the
likely
magnitude
of
the
effect
of
the
error
on
impingement
and
entrainment
(
I&
E)
estimates
and
the
benefits
results.

Section
2
presents
Case
Study
errors
and
Section
3
presents
Preamble
and
EBA
errors.
These
sections
distinguish
analytical
and
clerical
errors.
Analytical
errors
are
errors
in
the
calculation
of
I&
E
metrics
or
benefits
estimates.
Clerical
errors
result
from
document
production.
Such
errors
do
not
effect
results,
although
they
may
cause
confusion
for
readers.

2.1
Analytical
Errors
2.1.1
Calculation
of
Production
Foregone
The
model
used
to
estimate
production
foregone
was
incorrectly
executed
for
certain
cases.
The
error
was
systematic,
but
affected
the
results
differently
from
case
to
case,
and
species
to
species,
depending
on
peculiarities
of
individual
I&
E
records
for
particular
species
in
particular
years.
Specifically,
the
algorithm
used
to
calculate
production
foregone
performed
correctly
for
cases
where
loss
records
for
sequential
sets
of
fish
life
stages
were
present,
but
gave
incorrect
results
if
certain
life
stages
were
absent
from
the
loss
records.
We
corrected
the
algorithm
and
recalculated
benefits
using
corrected
estimates
of
production
foregone.
The
revised
values,
presented
in
Table
1,
do
not
differ
from
the
original
values
in
most
cases,
but
large
differences
appear
for
Seabrook
(
Part
F),
Monroe
(
Part
I),
and
several
Ohio
River
facilities
(
Part
C).

the

for
the

component
of
the

is
incorrectly
used
instead
of
the
expected
annual
cost
involving
5

The

states:

The

that
one

two
volunteers
can
provide
the
necessary

The
estimated
annual
cost
in
the

This

The

is
applied
as
a

for

The

states:

Combining

This
is
equivalent
to
an

Instead,

The

Chapter

Section

Section
G5­
7.2.2
develops
an
annualized
cost
for
monitoring
in
tidal
wetlands
where
the
equipment
cost
is
incorrectly
treated
as
a
recurring
annual
expense
and
the
daily
cost
for
the
labor
component
of
the
monitoring
is
incorrectly
used
instead
of
the
expected
annual
cost
involving
5
days
of
labor.

The
original
paragraph
in
G5­
7.2.2
states:

The
sampling
protocol
suggests
that
one
technician
and
two
volunteers
can
provide
the
necessary
labor.
The
estimated
annual
cost
in
the
first
year
of
monitoring
is
$
1,600.
This
cost
comprises
$
490
in
labor
for
the
three
workers
over
5
days
(
3
in
August
and
2
in
the
spring,
with
8­
hour
days,
$
15
per
hour
for
volunteers,
and
$
30
per
hour
for
the
technician).
The
$
1,100
in
equipment
costs
includes
two
fyke
nets
at
$
500
each
and
two
throw
traps
at
$
50
each
(
Neckles
and
Dionne,
1999).
The
annualized
equivalent
of
these
monitoring
costs
is
$
1,146
and
is
applied
as
a
per­
acre
cost
for
monitoring
in
this
HRC
valuation.

Instead,
the
correct
paragraph
in
G5­
7.2.2
should
read:

The
sampling
protocol
suggests
that
one
technician
and
two
volunteers
can
provide
the
necessary
labor.
The
estimated
annual
cost
in
the
first
year
of
monitoring
is
$
2,500.
This
cost
comprises
$
490
in
daily
labor
costs
for
the
three
workers
over
5
days
(
3
in
August
and
2
in
the
spring,
with
8­
hour
days,
$
15
per
hour
for
volunteers,
and
$
30
per
hour
for
the
technician).
The
$
1,100
in
equipment
costs
includes
two
fyke
nets
at
$
500
each
and
two
throw
traps
at
$
50
each
(
Neckles
and
Dionne,
1999).
The
annualized
equivalent
of
these
monitoring
costs,
treating
the
equipment
costs
as
a
one­
time
expense
in
year
one
and
the
labor
costs
as
a
recurring
expense
over
the
10
year
monitoring
period,
is
$
1,847
and
is
applied
as
a
per­
acre
cost
for
monitoring
in
this
HRC
valuation.

The
original
paragraph
in
G5­
7.2.3
states:

Combining
the
annualized
per­
acre
implementation
and
monitoring
costs
for
tidal
wetland
restoration
results
in
an
annualized
per­
acre
cost
for
tidal
wetland
restoration
of
$
7,904.
This
is
equivalent
to
an
annualized
cost
for
tidal
wetland
restoration
of
$
1.95
per
m2
of
restored
tidal
wetland
(
4,047
m2
=
1
acre)
which
is
incorporated
into
this
HRC
for
consistency
with
the
estimates
of
increased
fish
production
from
tidal
wetland
restoration
which
are
also
expressed
on
a
per
m2
basis.

it
to
increase
the
annualized

by

This
would
increase
the

reported
as

while
in
other
chapters
the
corresponding

were
reported
as
greater

This
apparent
discrepancy
occurs
because
I&

were
rounded
to
the
nearest

in
the

and
therefore
values

not
reported.
However,
the
actual

were
used
in
the

calculations,
and
therefore
corresponding
economic

are
greater
than
zero.

Benefits
of
Option
6
were
not
reported
in
the
Preamble
The
EBA
reports
benefits
of
a
sixth
option
(
Option
6)
that
was
added
to
the
national
benefits
analysis
after
the
Preamble
was
completed.
The
expected
reductions
in
I&
E
and
the
economic
benefits
of
Option
6
are
reported
in
Chapter
C4
of
the
EBA
but
not
in
the
Preamble.

3.1.2
Preamble,
Section
VI.
Best

for
Minimizing
Adverse
Environmental
Impact
at
Phase
II
Existing
Facilities
The
benefits
estimates
for
the
dry
cooling
option
(
called
Option
5
in
the
benefits
analysis)
have
been
updated.

The
statement
"
annual
benefits
of
$
138.2
million
for
impingement
reductions
and
$
1.33
billion
for
entrainment
reductions."
should
read
"
annual
benefits
of
$
143.9
million
for
impingement
reductions
and
$
1.39
billion
for
entrainment
reductions."

3.1.3
Concurrence
between
scaling
of
national
costs
and
benefits
In
the
Preamble,
the
number
of
facilities
represented
in
the
national
benefits
estimates
is
fewer
than
the
number
of
facilities
represented
in
the
national
cost
estimates.
This
discrepancy
does
not
appear
in
the
EBA.

SC10084
The
Preamble
uses
statistical
weighting
factors
to
extrapolate
costs
and
benefits
at
model
facilities
to
the
national
scale.
The
national
cost
estimates
reported
in
the
Preamble
are
correctly
scaled
to
represent
all
550
in­
scope
facilities.
However,
the
national
benefit
estimates
reported
in
the
Preamble
(
Exhibits
25­
34)
were
incorrectly
scaled
to
represent
only
539
in­
scope
facilities.
Therefore,
the
Preamble
reports
expected
total
baseline
losses
and
benefits
that
are
slightly
less
than
the
correct
total.
In
contrast
to
the
Preamble,
the
summary
of
costs
and
benefits
presented
in
the
EBA
is
consistently
scaled
to
represent
550
facilities.

3.1.4
Omission
of
Seabrook
from
national
extrapolation
In
the
Preamble,
the
case
study
results
from
the
Seabrook
facility
were
incorrectly
omitted
from
the
totals
reported
in
Exhibits
25­
34.
The
extrapolation
for
Oceans
reports
the
total
of
benefits
among
all
in­
scope
facilities
except
Seabrook.
This
results
in
a
minor
inaccuracy
in
the
baseline
loss
and
benefits
estimates
for
oceans
and
for
the
total
of
all
in­
scope
facilities.
In
contrast
to
the
Preamble,
the
analysis
reported
in
the
EBA
(
Chapters
C3
and
C4
and
Appendix
C1)
includes
the
Seabrook
results.

3.1.5
Estimated
percent
reductions
under
the
regulatory
options
Stratus
Consulting
still
has
some
uncertainty
about
the
exact
definitions
of
the
various
regulatory
options
and
their
effects
on
I&
E
loss
rates.
Thus,
the
options
as
defined
for
the
costs
may
not
be
the
same
as
the
options
defined
for
the
benefits.
Clarification
of
this
issue
is
needed
to
determine
if
there
is
an
inconsistency
that
requires
a
re­
analysis.
