Introduction
To
appropriately
assess
the
costs
and
benefits
of
the
LT2ESWTR,
it
is
necessary
to
estimate
how
many
plants
will
be
required
to
provide
treatment
as
a
result
of
the
rule
and
the
level
of
treatment
they
must
provide.
One
essential
factor
in
performing
this
assessment
is
determining
the
number
of
plants
that
may
be
able
to
get
Cryptosporidium
removal
credit
for
treatment
technologies
already
in
place.
This
appendix
discusses
the
various
technologies
that
could
earn
removal
credit
and
will
estimate
the
percentage
of
plants
by
size
category
that
have
or
will
have
such
technologies
in
place
prior
to
promulgation
of
the
LT2ESWTR.

Specifically,
this
appendix
addresses
the
following
toolbox
technologies:

°
Combined
filter
performance
°
Softening
plants
with
multiple
settling
basins
°
Conventional
plants
with
multiple
settling
basins
°
Multiple
filters
Data
sources
and
the
population
size
categories
are
discussed
first,
followed
by
an
analysis
of
each
treatment
configuration.
The
appendix
concludes
with
a
summary
of
log
removal
credits
for
existing
treatment.

A.
2
Data
Sources
A
number
of
information
sources
were
reviewed
to
determine
the
performance
and
layouts
of
surface
water
treatment
plants.
A
summary
of
each
source,
the
information
it
contains,
and
its
advantages
and
disadvantages
follow.

A.
2.1
The
Information
Collection
Rule
(
ICR),
USEPA
1996
The
ICR
was
a
survey
conducted
by
EPA
from
1997
through
1998.
It
consists
of
18
months
of
data
collected
from
all
large
systems
serving
over
100,000
people.
Information
in
the
survey
included
water
quality
parameters,
such
as
turbidity
and
pH,
along
with
process
units
in
the
plant
and
their
sequences.
The
ICR
survey
is
the
most
comprehensive
database
available
for
large
systems.

A.
2.2
Partnership
for
Safe
Drinking
Water
Data,
1999
Analyses
in
this
appendix
draw
from
the
Year
2000
annual
report
for
the
Partnership
for
Safe
Drinking
Water
(
the
Partnership),
as
well
as
additional
turbidity
data
gathered
and
analyzed
by
EPA.
The
Partnership
is
a
cooperative
effort
among
EPA
and
several
professional
water
associations.
Plants
in
the
Economic
Analysis
for
the
LT2ESWTR
Proposal
A­
2
June
2003
Partnership
undergo
voluntary
audit
programs
in
an
effort
to
improve
their
plant
performance
and
achieve
better
water
quality.
According
to
the
annual
report,
about
211
of
the
total
Partnership
plants
were
large
plants
serving
more
than
100,000
people,
81
were
medium
plants
serving
between
10,000
and
100,000
people,
and
33
were
small
plants
serving
less
than
10,000
people.
All
of
these
plants
were
surface
water
plants.
Because
of
this
representation,
the
survey
is
best
suited
for
use
with
large
systems.
It
is
less
appropriate
to
use
for
medium
systems,
although
with
a
sample
size
of
81
medium
plants,
it
is
probably
a
fair
representation
of
medium
plants.
It
is
probably
inadequate
to
represent
small
systems
as
its
small
plants
are
less
than
half
a
percent
of
the
small
plants
nationwide
and
most
of
the
plants
in
the
database
are
larger
systems.
Because
the
Partnership
is
a
voluntary
association
of
plants
actively
seeking
to
improve
water
quality,
these
plants
are
likely
to
perform
better
than
plants
nationwide.

A.
2.3
American
WaterWorks
Association
(
AWWA)
Water:\
Stats
Database,
1996
The
AWWA
Water:\
Stats
Database
contains
the
results
of
a
survey
of
the
AWWA's
members
conducted
in
1996.
It
contains
information
on
the
treatment
processes
in
place
at
the
plants
that
responded
to
the
survey
along
with
information
on
disinfection
byproducts
and
other
water
quality
parameters.
The
database
includes
information
on
1,134
treatment
plants.
Of
these,
377
are
large
plants,
722
are
medium
plants,
and
only
35
of
the
plants
are
small
plants.
Of
these
plants
540
were
surface
water
plants.
Because
of
the
large
number
of
medium
plants,
this
is
probably
the
best
available
source
of
data
for
medium
plants.
It
is
also
a
good
source
of
data
for
large
plants.
The
small
number
of
small
plants
probably
makes
this
source
less
adequate
for
characterization
of
small
plants.

A.
2.4
Community
Water
Systems
Survey
(
CWSS),
1995
The
CWSS
was
conducted
by
EPA
in
1995.
It
surveyed
2,000
community
water
systems
across
all
size
categories.
It
includes
information
on
the
type
of
treatment
processes
the
plants
have
in
place.
Although
the
sample
size
in
this
survey
is
adequate
to
represent
plants
in
all
size
categories
nationwide,
there
are
some
significant
problems
with
using
this
data
source
to
estimate
in­
place
treatment
technologies.
First,
there
were
a
large
number
of
non­
responses
to
the
survey,
especially
by
small
systems.
There
was
also
a
great
deal
of
confusion
over
the
wording
of
many
of
the
questions
on
the
survey,
leading
to
difficulty
in
classifying
many
of
the
process
units.
This
resulted
in
a
large
number
of
processes
being
classified
in
"
other"
categories.
As
a
result,
this
survey
is
probably
the
least
reliable
source
used
in
this
analysis.

A.
2.5
National
Rural
Water
Association
(
NRWA)
Survey,
2000
This
survey
was
conducted
of
members
of
the
NRWA
in
1999­
2000.
It
includes
data
on
water
quality
parameters,
as
well
as
treatment
configurations.
The
survey
includes
information
on
129
small
surface
water
systems,
the
largest
survey
of
small
systems
available.
It
should
be
noted,
however,
that
the
survey
still
only
encompasses
about
1
percent
of
small
systems
nationwide
and
the
plants
were
not
necessarily
chosen
to
obtain
a
representative
nationwide
sampling
of
various
types
of
systems.
The
water
quality
data
also
only
includes
two
samples
per
plant
 
one
in
the
Summer
and
one
in
the
Winter
 
instead
of
the
monthly
data
included
in
other
surveys.
Therefore,
although
this
is
the
best
data
source
available
for
small
systems,
it
is
still
very
limited
in
its
usefulness.

These

analyzed
the

of
these

rules
on
surface

systems.
The
reports
include
characterization
of
plants'
performance
prior

the

of
these
rules
and
predictions
concerning
what
types
of

that

2.7
Interview
of
Industry
Experts
To
assess
the
applicability
of
the
various
data
sources
and
the
assumptions
made
about
them,
industry
experts
were
interviewed
on
the
topics
analyzed
in
this
appendix.
Experts
on
the
subjects
of
small
systems,
large
systems,
data
surveys,
and
treatment
technologies
were
interviewed.
The
experts
were
asked
questions
concerning
the
validity
and
applicability
of
the
data
sources
listed
above.
They
were
also
questioned
regarding
the
reasonableness
of
the
assumptions
in
this
appendix.

A.
3
Comparison
and
Use
of
Data
Sources
Using
the
expert
opinion
and
information
from
each
of
the
sources,
determinations
were
made
on
which
data
sources
to
use
for
each
of
the
size
categories
and
treatment
categories.

A.
3.1
Large
Systems
The
ICR
is
a
comprehensive
survey
that
was
mandated
of
all
large
systems
in
the
country.
The
large
number
of
systems
makes
it
the
most
comprehensive
and
least
biased
source
of
information
for
large
systems.
In
addition,
although
the
information
on
treatment
trains
was
self­
reported,
EPA
performed
a
data
quality
check
that
should
have
lessened
inconsistencies
in
reporting.
Both
Water:\
Stats
and
CWSS
were
voluntary
surveys
with
non­
response
rates
much
greater
than
50
percent.
The
low
response
rate
could
lead
to
some
bias
in
the
data.
There
was
also
little
independent
review
of
the
data,
which
means
that
there
could
be
inconsistent
labeling
of
process
units.
This
was
a
noted
problem
in
CWSS.
Therefore,
ICR
data
was
used
preferentially
for
large
systems
to
obtain
treatment
train
data.
The
Partnership
data
were
used
for
information
on
turbidity.
For
treatment
processes
that
could
not
be
determined
from
ICR
data,
Water:\
Stats
or
the
CWSS
was
used.

A.
3.2
Medium
Systems
Water:\
Stats
and
CWSS
are
the
two
main
sources
of
data
about
treatment
trains
for
medium
water
systems.
They
contain
similar
numbers
of
medium
systems
and
both
were
voluntary
surveys
with
high
non­
response
rates.
There
was
some
confusion
noted
with
the
listing
of
technologies
in
the
CWSS
survey
that
may
have
led
to
a
higher
rate
of
misclassification
than
with
Water:\
Stats.
There
was
not
enough
information,
however,
to
clearly
favor
one
data
source
over
the
other,
so
the
two
were
considered
equivalent,
and
when
data
existed
in
both
databases
they
were
averaged.

Medium
and
large
plants
have
been
found
to
be
similar
both
in
terms
of
water
quality
and
treatment
effectiveness.
Examining
the
medium
and
large
plants
in
Water:\
Stats
revealed
that
source
water
quality
as
measured
by
source
turbidity
and
finished
water
quality
as
measured
by
disinfection
by­
Economic
Analysis

June
2003
products
were
nearly
identical
for
medium
and
large
plants
(
see
USEPA
2003d
Appendix
B).
Therefore,
the
types
and
effectiveness
of
the
treatment
processes
are
thought
to
be
fairly
similar,
and
using
data
from
large
plants
(
ICR
data)
for
medium
plants
results
in
an
acceptable
estimate
of
medium
plants.
For
this
reason,
ICR
data
were
used
for
medium
plants
when
specific
information
on
medium
plants
was
unavailable.
For
turbidity,
data
from
the
Partnership
were
used.
The
Partnership
data
are
an
aggregate
of
medium
and
large
plants,
but
they
are
acceptable
to
apply
to
medium
plants.

A.
3.3
Small
Systems
Water:\
Stats
database
contains
information
on
only
33
small
plants.
Therefore,
this
source
was
not
used
for
small
plants.
CWSS
contains
the
largest
number
of
small
plants
of
all
the
data
sources.
The
size
of
the
sample
may
offset
the
possible
misclassification
and
the
low
response
rate.
The
NRWA
survey
has
a
smaller
number
of
plants
that
are
less
representative
of
the
national
population.
However,
the
survey
was
conducted
by
making
site
visits
to
the
plants,
so
there
is
probably
less
miscategorization
of
data.
For
that
reason,
NRWA
was
used
as
the
preferential
database
for
small
systems
with
CWSS
being
used
when
data
were
unavailable
from
NRWA.
For
turbidity
data,
the
data
collected
for
the
proposed
LT1ESWTR
RIA
(
USEPA
2000l)
was
used,
as
it
contained
the
largest
number
of
plants
and
had
better
quality
data.

A.
4
Population
Size
Categories
Evaluated
Because
of
the
limited
number
of
plants
in
many
of
the
above
sources,
it
was
decided
not
to
split
plants
into
nine
population
categories
as
is
traditionally
done
in
such
analyses.
Such
a
split
would
leave
many
of
the
small
size
categories
with
too
few
plants
to
be
statistically
significant.
Therefore,
only
the
small
(<
10,000),
medium
(
10,001­
100,000),
and
large
(>
100,000)
population
size
categories
were
used
for
analysis.

A.
5
Combined
Filter
Performance
The
combined
filter
performance
option
requires
systems
to
achieve
turbidity
of
0.15
NTU
in
the
combined
filter
effluent
(
CFE).
Conventional
plants
will
need
to
meet
the
requirements
of
0.3
NTU
95
percent
of
the
time
in
the
CFE
per
the
IESWTR
and
the
LT1ESWTR.
Plants
that
can
optimize
their
process
to
achieve
0.15
NTU
95
percent
of
time
in
the
CFE
will
be
able
to
receive
an
additional
0.5
log
Cryptosporidium
removal
credit
for
the
LT2ESWTR.

A.
5.1
Medium
and
Large
Plants
 
Turbidity
To
determine
the
number
of
medium
and
large
plants
that
can
achieve
the
Cryptosporidium
reduction
credit
for
the
combined
filter
performance
option
prior
to
implementation
of
the
IESWTR,
1999
data
from
the
Partnership
were
examined.
The
data
include
turbidity
results
from
220
plants
of
the
325
that
are
members
of
the
Partnership.
As
noted
earlier,
most
plants
in
the
Partnership
are
in
the
medium
and
large
size
categories.
So
this
data
set
is
assumed
to
be
representative
of
medium
and
large
plants.

5.2
Pre­
IESWTR
Exhibit
A.
1
summarizes
these
data,
showing
the
percentage
of
plants
that
exceed
monthly
95th
percentile
turbidities
of
0.1,
0.2,
and
0.3
for
a
given
number
of
months.
To
interpret
the
exhibit,
consider
the
following
example:
the
value
for
1
month
and
0.3
NTU
is
20
percent.
This
means
that
20
percent
of
the
plants
exceeded
0.3
NTU
in
their
CFE
for
at
least
1
month
out
of
the
year.
Conversely,
80
percent
of
the
plants
never
exceeded
a
95th
percentile
turbidity
value
of
0.3
NTU.

To
estimate
the
percentage
of
plants
in
the
Partnership
below
0.15
for
all
months,
linear
interpolation
was
used.
From
Exhibit
A.
1,
estimates
of
plants
above
0.1
and
0.2
NTU
for
any
given
month
are
42
percent
and
74
percent,
respectively.
The
value
for
0.15
NTU
would
then
be:

(
42%
+
74%)/
2
=
58%.

Therefore,
42
percent
(
100
percent
­
58
percent)
of
plants
did
not
exceed
0.15
NTU
and
met
the
requirement
to
obtain
the
0.5
log
Cryptosporidium
removal
credit
(
less
than
0.15
NTU
95
percent
of
the
time).

To
directly
extrapolate
Partnership
estimates
to
all
medium
and
large
plants
nationwide
may
be
misleading.
The
plants
in
the
Partnership
tend
to
be
the
largest,
best
run
plants
in
the
country.
Also,
by
virtue
of
their
voluntary
participation
in
the
program,
these
plants
are
likely
to
be
dedicated
to
improving
plant
performance.
This
may
lead
to
plants
in
the
Partnership
performing
better
than
those
not
in
the
Partnership.
Therefore,
other
information
was
evaluated
to
determine
the
percent
of
medium
and
large
plants
that
can
obtain
these
values.

The
Technical
Work
Group
(
TWG)
for
the
IESWTR
estimated
the
number
of
conventional
systems
that
would
need
to
take
action
to
achieve
95th
percentile
turbidity
goals
of
0.1,
0.2,
and
0.3
NTU.
The
TWG
estimated
that
there
would
be
no
difference
in
the
number
of
plants
that
would
need
to
make
changes
to
achieve
0.1
and
0.2
NTU;
there
would
only
be
changes
in
the
type
of
treatment
they
would
use.
Examining
Exhibit
5.2
of
the
IESWTR
RIA
(
USEPA
1998b)
shows
the
TWG
determined
that
20
percent
of
medium
systems
and
23
percent
of
large
systems
would
not
have
to
make
changes
to
comply
with
a
0.1
or
0.2
NTU
95th
percentile
turbidity
limit.
These
values
were
used
to
represent
the
levels
that
all
plants
could
achieve
prior
to
implementation
of
the
LT2ESWTR.
The
Partnership
plants
were
not
analyzed
separately
as
the
IESWTR
analysis
would
have
already
taken
these
plants
into
account.

IESWTR
Exhibit
A.
2
summarizes
data
from
1999
or
before,
prior
to
implementation
of
the
IESWTR.
It
is
expected
that
many
plants
will
improve
filter
performance
to
comply
with
the
requirements
of
IESWTR.
The
Regulatory
Impact
Analysis
(
RIA)
for
the
IESWTR
(
USEPA
1998b)
estimates
that
approximately
51
percent
of
medium
and
46
percent
of
large
systems
will
modify
their
treatment
processes
to
comply
with
the
rule
requirements.
Plants
are
expected
to
make
changes
such
as
adding
additional
polymer,
automating
filter
monitoring
and
control,
and
implementing
better
filter
inspection
and
maintenance
programs.
These
are
plants
that
would
not
have
been
performing
at
these
turbidity
levels
in
1999,
but
are
predicted
to
achieve
lower
turbidity
limits
of
at
least
0.3
NTU
before
the
promulgation
of
the
LT2ESWTR.
It
is
reasonable
to
assume
that
some
plants
that
make
changes
to
achieve
0.3
NTU
will
also
be
able
to
achieve
0.15
NTU
without
additional
changes.
To
estimate
the
percentage
of
these
plants
that
will
achieve
the
additional
removal
to
levels
of
0.15
NTU
95
percent
of
the
time
after
implementation
of
the
LT1ESWTR
and
IESWTR,
the
following
assumptions
were
used:

°
The
ratio
of
plants
that
achieve
0.15
NTU
to
those
that
achieve
0.3
NTU
is
the
same
for
the
universe
of
plants.

°
Based
on
Partnership
data
(
Exhibit
A.
1),
about
half
the
plants
that
achieve
0.3
NTU
(
80
percent)
also
achieve
0.15
NTU
(
42
percent).

Although
the
Partnership
plants
tend
to
be
better
run
on
the
whole,
many
of
the
elements
of
the
Partnership
program
are
similar
to
those
required
by
the
IESWTR.
For
example,
both
the
IESWTR
and
the
Partnership
require
filter
benchmarking
and
peer
reviews.
Therefore,
using
the
ratio
of
Partnership
plants
that
achieve
0.3
NTU
to
those
that
achieve
0.15
NTU
is
a
reasonable
proxy
for
how
all
plants
might
be
expected
to
perform
after
the
IESWTR
and
LT1ESWTR
are
implemented.
Applying

large

expected

to

the

(
51
and
46

respectively)
gives
26

23
percent
of
medium

respectively.
For

for

=

=

It
should
be
noted
that
these
numbers
may
be
slightly
optimistic
because
many

may
also

Small
Systems
Small
systems,
those
serving
10,000
people
or
less,
are
evaluated
separately
from
medium
and
large
systems
for
several
reasons.
Small
systems
often
have
better
source
water
quality
and,
therefore,
require
less
rigorous
treatment
technologies.
They
also
tend
to
have
less
advanced
control
systems,
less
sophisticated
monitoring
equipment,
and
less
operator
training.
Small
plants
tend
to
use
conventional
treatment
trains
less
often
than
medium
and
large
plants.
Small
systems
typically
prefer
package
plants1
including
such
technologies
as
membranes,
direct
filtration,
and
cartridge
filtration.
Although
such
plants
may
be
able
to
obtain
credit
for
those
alternative
technologies,
they
would
not
obtain
credit
for
combined
filter
performance.

A
review
of
available
data
showed
only
two
available
data
sources
for
small
plants:
NRWA
data
and
turbidity
data
collected
for
the
proposed
LT1ESWTR
RIA.
The
NRWA
survey
included
data
from
Economic
Analysis
for
the
LT2ESWTR
Proposal
A­
9
June
2003
129
surface
water
plants.
There
are
several
issues
to
take
into
account
when
considering
the
NRWA
data.
The
first
is
the
small
sample
size.
There
are
only
129
plants
in
the
survey
of
which
only
51
are
conventional
plants;
only
conventional
plants
would
be
eligible
for
combined
filter
performance
credit.
The
plants
were
also
not
selected
to
represent
a
statistically
valid
nationwide
sampling.
The
second
issue
is
that
the
NRWA
data
consist
of
only
two
grab
samples
taken
during
the
year
in
contrast
to
the
Partnership
data,
which
consists
of
the
95th
percentile
values
of
samples
taken
every
15
minutes.
Such
grab
samples
would
likely
miss
seasonal
peaks,
as
well
as
system
spikes.
Therefore,
the
samples
are
more
likely
to
be
representative
of
an
average
or
50th
percentile
value
than
a
95th
percentile
value.
For
this
reason,
the
data
collected
for
the
LT1ESWTR
were
used
as
the
primary
data
source.

The
RIA
for
the
proposed
LT1ESWTR
examined
turbidity
data
for
187
small
surface
water
plants
from
13
states.
Two
of
these
states
reported
95th
percentile
turbidity
data,
six
of
these
states
reported
multiple
daily
turbidity
values,
and
five
states
reported
maximum
daily
values.
These
regular
values
give
a
much
better
representation
of
the
performance
of
small
plants
than
the
two
annual
points
of
the
NRWA
data.
The
data
showed
that
27
percent
of
small
plants
never
exceeded
a
95th
percentile
turbidity
value
of
0.15
NTU
and
48
percent
of
small
plants
never
exceeded
0.3
NTU.
Therefore,
27
percent
of
plants
were
assumed
to
be
able
to
perform
well
enough
to
obtain
the
combined
filter
performance
Cryptosporidium
removal
credit.

The
NRWA
data
were
also
examined
to
check
the
reasonableness
of
the
results
based
on
the
proposed
LT1ESWTR
RIA.
Exhibit
A.
4
shows
the
maximum
turbidity
values
of
small
conventional
plants
in
the
NRWA
survey.
Sixty
percent
of
the
plants
had
both
samples
below
0.15
NTU.
As
mentioned
earlier,
this
is
probably
closer
to
the
50th
percentile
than
the
95th
percentile.
The
RIAs
for
the
IESWTR
and
the
proposed
LT1ESWTR
assumed
that
plants
would
target
0.1
NTU
under
regular
operation
to
meet
0.2
NTU
limits
95
percent
of
the
time.
To
be
consistent
with
these
analyses,
plants
were
estimated
to
target
an
average
of
0.075
NTU
in
order
to
achieve
0.15
NTU
95
percent
of
the
time.
Examining
Exhibit
A.
4
shows
that
approximately
30
percent
of
small
conventional
plants
never
exceeded
0.075
NTU
in
the
NRWA
survey.
This
value
is
less
than
the
value
for
medium
and
large
plants
and
close
to
the
value
derived
from
the
proposed
LT1ESWTR
data.
Therefore,
the
numbers
derived
from
the
proposed
LT1ESWTR
data
were
considered
supported
by
the
NRWA
data.
As
mentioned
above,
the
smaller
plants
would
not
be
expected
to
perform
as
well
because
of
less
operator
training,
less
sophisticated
monitoring
and
control
equipment,
and
less
redundancy
in
systems.
As
a
result,
problems
in
a
single
piece
of
equipment
are
more
likely
to
affect
the
process.

In
addition
to
evaluating
performance
of
conventional
filtration
in
small
plants,
this
analysis
recognizes
that
there
is
a
much
smaller
percentage
of
small
conventional
plants
than
in
large
and
medium
systems.
Approximately
40
percent
of
the
NRWA
plants
were
conventional.
If
only
27
percent
of
these
can
meet
the
0.15
NTU
performance
criteria
in
the
CFE
95
percent
of
the
time,
then
only
11
percent
(
0.4*
0.27
=
0.11)
of
small
plants
nationwide
would
qualify
for
the
0.5
log
Cryptosporidium
removal
credit.
The
estimate
(
11
percent)
was
used
to
represent
Pre­
LT1ESWTR
removal
credit
for
small
plants.

LT1ESWTR.
The
RIA
for
the
proposed
LT1ESWTR
estimated
that
41
percent
of
small
surface
water
plants
would
make
filtration
improvements
to
comply
with
the
rule.
Therefore,
41
percent
of
small
systems
would
achieve
0.3
NTU.
To
calculate
the
percent
that
will
achieve
0.15
NTU,
the
ratio
of
small
plants
achieving
0.15
NTU
to
those
achieving
0.3
NTU
from
the
LT1ESWTR
RIA
data
(
0.56)
is
used,
assuming
the
ratio
is
constant
as
in
the
large

analysis.
Using
this
ratio
gives
23
percent
(
0.41
x
0.56)
of
small
plants
that
would

limit
95

time.
Added
to
the

gives
a

of

Plants
with
multiple
sedimentation
basins
in
series
will
generally
receive
a
0.5
log
removal
credit
for
the
LT2ESWTR.
These
plants
could
be
softening
or
conventional
plants.
Examining
the
ICR
database
for
softening
plants,
all
plants
listed
as
"
two
stage
softening
plants"
or
as
"
coagulation/
sedimentation
softening
plants"
meet
this
requirement.
There
were
16
and
18
percent
of
all
softening
plants
in
these
categories,
respectively.
Therefore,
this
analysis
estimates
that
34
percent
(
16
+
18%)
of
softening
plants
could
qualify
for
the
credit.
As
there
was
no
such
data
in
CWSS
or
Water:\
Stats,
the
ICR
value
was
used
for
all
medium
and
large
plants.
NRWA
indicated
1.5
percent
of
small
systems
had
multiple
basins.
This
percentage
was
used
for
small
softening
systems.
To
estimate
the
total
percent
of
softening
plants
with
multiple
sedimentation
basins,
the
percentage
of
softening
plants
assumed
to
have
multiple
basins
(
34
percent)
was
then
multiplied
by
the
total
percent
of
all
plants
that
are
softening
based
on
CWSS
data.

ICR
data
show
that
approximately
3
percent
of
large
conventional
plants
have
multiple
sedimentation
basins
in
series.
Water:\
Stats
and
CWSS
do
not
distinguish
the
number
of
basins,
only
whether
they
are
present
or
not.
The
NRWA
survey,
however,
did
provide
data
on
multiple
basins,
showing
that
1.5
percent
of
small
systems
had
multiple
basins.
This
number
was
used
for
small
systems.
The
ICR
number
was
used
for
medium
and
large
plants.
The
total
number
of
plants
with
multiple
sedimentation

in

would
be
a
sum
of
the

Multiple

EPA
intends
to
grant
a
0.5
log
credit
for
plants
having
multiple
filters
in
series.

ICR
and
CWSS
did
not
differentiate
between
GAC
alone
and
GAC
as
a
polishing
filter.
The
Water:\
Stats
database,
however,
does
contain
more
detailed
information
on
GAC
filters.
Exhibit

shows
the
percent
of
medium
and
large
plants
that
have
a
GAC
filter
in
addition
to
conventional
filters
as
listed
in
Water:\
Stats.
The
NRWA
survey
showed
no
plants
that
had
a
GAC
filter
following
a
conventional
filter.
As
with
adsorption
clarifiers,
it
was
assumed
that
no
plants
had
such
technologies
in
addition
to
a
conventional
treatment
train,
but
are
used
in
addition
to
other
processes
such
as
direct
filtration.
Therefore,
no
small
plants
were
assumed
to
have
this
technology.

Summary
Treatment
configurations
in
place
at
the
time
of
rule
promulgation
are
considered
"
credits."
In
other
words,
neither
the
costs
nor
the
benefits
of
those
configurations
can
be
ascribed
to
the
LT2ESWTR.
Plants
with
these
configurations
are
placed
into
a
bin
which
is
lowered
by
either
0.5
log
or
1.0
log
than
what
their
occurrence
would
require
of
them.
For
example,
a
system
in
a
2.0
log
treatment
bin
that
had
a
1.0
log
treatment
credit
would
need
only
install
a
technology
that
obtained
1.0
log
credit.
In
this
way,
neither
the
costs
nor
the
benefits
from
existing
technologies
are
ascribed
to
this
rule.

Exhibit
A.
7
summarizes
the
percent
of
plants
with
treatments
in­
place
that
can
achieve
Cryptosporidium
reduction
credit
for
LT2ESWTR
beyond
conventional
treatment.
It
is
possible
that
some
plants
could
have
multiple
technologies
for
which
they
could
receive
credit.
To
determine
the
percent
of
plants
that
might
achieve
multiple
credits,
the
chance
of
a
plant
having
each
of
the
three
technologies,
combined
filter
performance,
multiple
sedimentation
basins,
and
multiple
filters
was
considered
to
be
independent
of
each
other.
Therefore,
the
chance
of
a
small
plant
having
lower
finished
water
turbidity
to
meet
the
combined
filtration
performance
requirement
and
multiple
sedimentation
basins
is:

(
0.34)*(

=
1.0%.

Characterizing
Cryptosporidium
Concentration
and
Methods
for
Predicting
Plant
Binning
B.
1
Introduction
This
appendix
describes
the
statistics
used
to
characterize
Cryptosporidium
occurrence
distributions.
It
then
explains
how
the
monitoring
frequency
and
calculation
of
the
average
concentration
for
bin
determination
were
chosen.
Lastly,
it
presents
the
data
used
to
determine
Cryptosporidium
occurrence
and
the
likelihood
of
a
plant
being
categorized
into
a
given
bin
for
each
regulatory
alternative.

B.

Appropriate
Statistical
Measure
to
Characterize
Source
Waters
EPA
considered
a
variety
of
statistical
measures
by
which
Cryptosporidium
concentrations
in
systems
could
be
characterized
for
the
purpose
of
determining
whether
additional
treatment
should
be
prescribed.
These
measures
included
the
arithmetic
mean,
median,
90th
percentile,
and
maximum.
Consistent
with
Microbial­
Disinfection
Byproduct
Advisory
Committee
(
Advisory
Committee)
recommendations,
EPA
is
proposing
that
Cryptosporidium
levels
be
characterized
by
the
arithmetic
mean.
Use
of
the
mean
is
advantageous
for
several
reasons.
The
mean
can
be
estimated
more
reliably
than
other
statistical
measures.
For
example,
with
a
limited
number
of
samples,
the
confidence
interval
around
the
mean
is
substantially
narrower
(
i.
e.,
less
uncertain)
than
for
a
90th
percentile
estimate.
Defining
a
treatment
trigger
based
upon
a
maximum
value
would
be
much
less
reliable
than
basing
it
on
a
computation
involving
multiple
values,
due
to
the
uncertainty
associated
with
any
single
sample
measurement.

The
mean
concentration
also
directly
relates
to
the
average
risk
of
the
exposed
population
and,
therefore,
provides
a
good
measure
for
indicating
relative
risks
from
one
site
versus
another
(
e.
g.,
doubling
the
source
water
average
concentration
corresponds
to
about
a
doubling
of
the
risk,
assuming
the
same
level
of
treatment
at
both
sites).
In
contrast,
the
median
would
not
be
an
informative
or
appropriate
characterization
because
of
the
large
numbers
of
non­
detection
measurements
expected
to
occur,
resulting
in
a
large
number
of
sites
with
median
values
equal
to
zero.
The
median
would
fail
to
distinguish
differences
between
sites
that
had
half
or
more
of
their
measurements
as
zero
with
the
rest
being
positive
values
and
sites
which
truly
had
measurements
of
zero.

Rates

Misclassification
Having

performance
based
on
results
with
EPA
Methods
1622/
23
in
the
Information
Collection
Rule
Supplemental
Surveys
(
ICRSS),
and
having
established
the
mean
as
the
appropriate
statistical
measure
to
classify
source
water
Cryptosporidium
levels,
a
critical
issue
for
the
Advisory
Committee
was
how
accurately
systems
could
be
classified
within
a
bin
structure
by
a
monitoring
program.
This
analysis
illustrates
the
impact
of
the
number
of
samples
analyzed
and
the
averaging
technique
(
e.
g.,
maximum
running
average
vs.
simple
mean)
on
system
misclassification
rates.
Economic
Analysis
for
the
LT2ESWTR
Proposal
B­
2
June
2003
With
perfect
information
on
mean
source
water
Cryptosporidium
levels,
it
would
be
possible
to
assign
systems
to
bins
without
error.
No
such
perfect
information
exists,
so
the
Advisory
Committee
recommended
a
sampling
and
testing
strategy
relying
on
Method
1622
or
1623.
Each
source
water
would
require
a
number
of
samples
to
ensure
a
reasonably
accurate
estimate
of
its
mean
Cryptosporidium
concentration.

The
calculated
mean
that
systems
derive
from
monitoring
results
will
differ
from
the
true
mean
because
of
sampling
and
measurement
error.
Sampling
error
occurs
because
only
a
finite
volume
of
water
is
assayed
on
each
occasion.
Since
oocysts
are
very
disperse
in
the
water,
many
10­
L
samples
will
contain
zero
oocysts
when
the
concentration
is
low,
but
greater
than
zero.
For
example,
EPA
would
expect
most
10­
L
samples
to
contain
zero
oocysts
when
the
true
concentration
in
the
water
body
being
sampled
is
0.05
oocysts/
L.

Sampling
error
also
occurs
because
samples
are
collected
at
relatively
low
frequency.
Since
Cryptosporidium
concentrations
may
experience
significant
temporal
variation,
infrequent
sampling
is
likely
to
miss
rare
peaks
in
concentration
and,
therefore,
underestimate
the
true
mean
occurrence
level.
Conversely,
if
a
sample
event
happens
to
coincide
with
a
rare
occurrence
peak,
the
calculated
mean
will
overestimate
the
true
mean
occurrence
level.
By
prescribing
a
larger
number
of
samples
at
equal
intervals
over
a
long
period
of
time,
this
type
of
sampling
error
can
be
reduced
to
a
relatively
low
level.

Measurement
error
occurs
because
the
total
oocyst
count
from
a
volume
assayed
does
not
usually
equal
the
total
number
of
oocysts
that
were
present.
Studies
of
recovery
indicate
that
the
percentage
of
oocysts
lost
during
the
measurement
process
is
variable,
most
often
falling
between
15
percent
and
65
percent
(
based
on
ICRSS
data).
Because
the
Advisory
Committee
recommended
that
systems
be
assigned
to
bins
based
on
total
oocyst
counts
uncorrected
for
recovery,
EPA
does
not
treat
average
recovery
as
a
source
of
error.
However,
the
variability
of
recovery
around
the
mean
contributes
to
error.

To
estimate
how
these
errors
would
affect
the
assignment
of
systems
to
bins,
EPA
constructed
a
Monte
Carlo
model
that
dealt
with
the
error
components
in
the
following
manner:

°
Finite
volume
assayed
 
The
model
defines
the
number
of
oocysts
present
in
a
10­
L
volume
as
a
Poisson
random
variable,
whose
mean
is
the
product
of
measurement
recovery,
volume
assayed,
and
concentration
at
the
time
of
sampling.

°
Finite
number
of
samples
 
True
concentration
varies
over
time
as
a
random
variable.
Concentration
is
modeled
to
vary
in
such
a
way
that
its
natural
logarithm
is
normally
distributed
with
standard
deviation
1.762.
This
value
was
selected
based
on
Bayesian
analysis
of
survey
data
(
see
Chapter
4)
and
on
expert
opinion
that
at
any
given
site
the
Cryptosporidium
concentration
would
vary
within
a
three
order
of
magnitude
concentration
range
95
percent
of
the
time;
i.
e.,
2.5
percent
of
the
time
the
concentration
would
be
less
than
X,
and
2.5
percent
of
the
time
the
concentration
would
exceed
1000X.

°
Variable
recovery
 
Based
on
laboratory
performance
in
ICRSS,
EPA
assumed
for
the
model
an
average
recovery
among
all
laboratories
of
40
percent
with
a
relative
standard
deviation
of
50
percent.
Recovery
is
modeled
as
a
Beta
random
variable
with
parameters
(
a,
b)
=
(
2,3).
Mean
recovery
is
therefore
a/(
a
+
b)
=
2/(
2
+
3)
=
0.4.
The
standard
deviation
of
recovery
is
0.2,
which
is
half
the
mean
recovery.

With
this

source

was

error
rates
in

to

under

included

18,
24,
36,
and
48
samples
collected
over
a
2­
year
period.
System
bin
assignments
were
based
on
comparing
a
sample
statistic
with
the
selected
bin
boundaries.
Sample
statistics
included
the
mean,
maximum,
2nd
highest,
3rd
highest,
and
maximum
running
annual
average
(
Max­
RAA).
(
Results
are

Exhibits

and

show
how
the
probabilities
of
assignment
to
Bins
1
through
4
vary
with
the
true
source
water
mean
concentration
when
the
Max­
RAA
is
used
with
24
samples
assayed
over
a
2­
year
period
(
producing
13
annual
averages).
Table
results
are
based
on
1,000
simulated
monitoring
data
sets.
Note
that
because
monitoring
results
will
not
be
corrected
for
recovery,
the
parameter
to
be
considered
when
assessing
error
in
bin
assignment
is
the
true
mean
source
water
concentration
multiplied
by
40
percent
(
the
estimated
average
method
recovery).
For
example,
Exhibit
B.
1
indicates
that
if
the
true
mean
is
0.316
oocysts/
L,
and
the
true
mean
multiplied
by
40
percent
recovery
is
0.126
(
0.316
×
0.4),
there
is
a
12.9
percent
probability
of
this
water
being
classified
in
the
no
action
bin,
an
85.9
percent
probability
of
being
classified
in
Bin
2
(
the
correct
bin
for
this
water),
and
about
a
1
percent
probability
of
being
classified
in
Bin
3.

Assignment
errors
are
most
likely
when
the
true
mean
is
close
to
a
bin
boundary.
For
example,
Exhibit
B.
1
indicates
that
a
water
with
a
true
mean
(
multiplied
by
40
percent
recovery)
of
0.075
oocysts/
L
has
about
a
60
percent
probability
of
being
classified
in
Bin
2
and
a
40
percent
probability
for
Bin
1.
Notice
that
classification
high
is
more
likely
than
classification
low
for
these
cases.
This
is
because
the
Max­
RAA
tends
to
slightly
overestimate
the
true
mean.
In
contrast,
if
the
true
mean
concentration
is
in
the
middle
of
Bin
2,
then
there
is
about
a
90
percent
probability
of
being
classified
in
Bin
2.

Exhibit

shows
equivalent

for

over

Again,
assignment
errors
are
most
likely
when
the
true
mean
is
close
to
a
bin
boundary.
Notice
that
the
likelihood
of
a
source
water
being
misclassified
high
is
lower
than
for
the
Max­
RAA
based
on
24

For
example,
Exhibit

indicates
that
if
the
true
mean
is
0.075
oocysts/

then
there
is
about
a
65
percent
probability
of
being
classified
in

and
about
a
35
percent
probability
of
being
classified
in

If,
however,
the
true
mean
is
in
the
middle
of

then
there
is
a
greater
than
95

Based

Simple
Mean
with
48
Samples
One
way
the
Advisory
Committee
members
evaluated
the
significance
of
system
misclassification
in
bin
assignments
was
to
consider
a
water
where
the
true
mean
is
0.5
log
(
i.
e.,
factor
of
3.16)
from
a
bin
boundary.
This
case
was
assessed
both
when
the
true
mean
is
a
half
log
below
a
bin
boundary
and
when
the
true
mean
is
a
half
log
above
a
bin
boundary.
Misclassifying
such
a
water
in
a
lower
bin
would
suggest
that
the
monitoring
was
not
protective
of
public
health,
since
the
relatively
high
occurrence
level
would
go
unaddressed.
Both
the
Max­
RAA
based
on
24
samples
and
the
simple
mean
based
on
48
samples,
each
over
a
2­
year
monitoring
period,
provided
approximately
the
same
level
of
protection
against
this
kind
of
error.
For
example,
for
a
water
with
a
true
mean
at
0.5
log
above
the
boundary
between
Bin
1
and
Bin
2
(
0.075
oocysts/
L),
the
rates
of
misclassification
into
the
lowest
bin
for
the
24­
sample
Max­
RAA
and
the
48­
sample
simple
mean
are
1.7
percent
(
0.017)
and
1.4
percent
(
0.014),
respectively.

Two
graphs
are
provided
that
clearly
show
the
tendency
for
misclassification
under
the
Preferred
Alternative.

the

Misclassifying

too
high
relative
to

would
potentially
result
in
systems
taking
costly
and
unnecessary
steps
to
reduce

As
shown
by
Exhibits
B.

and
B.

the
48­

provides
greater
protection
against
this
type
of
error
than
does
the
Max­
RAA,
although
monitoring
costs
will
be
twice
as
high.
Given
the
concerns
for
bias
(
high
or
low)
in
assigning
systems
to
bins,
the
Advisory
Committee
recommended
that
either
the
Max­
RAA
or
the
48­
sample
simple
mean
be
used
to
provide
sufficiently
reliable
estimates
for
bin
determination
under
LT2ESWTR.

The
measured
amount
of
Cryptosporidium
may
be
different
than
the
actual
or
"
true"
concentration
because
of
sampling
errors
and
method
limitations.
Exhibits

and
B.

show
for
a
given
"

concentration
the
percentage
of
time
that
a
sample
would
be
classified
in
each
bin.
(
This
section
differs
from
section
B.
3,
which
factors
in
recovery
in
determining
probability
of
misclassification).
The
binning
central

is

all
three

Rule
(
ICR),
ICR
Supplemental
Survey
Large

(
ICRSSL),
and
ICR
Supplemental
Survey
Medium
Systems
(
ICRSSM)).
The
percentage
of
plants
classified
in
each
bin
depends
on
method
errors
such
as
recovery,
false
positives,
and
analyst
error,
as
well
as
accounting
for
sample
size
and
the
fact
that
the
concentration
in
a
given
sample
may
under­
or
over­
represent
the
concentration
in
the
larger
water
body.

AIDS/
Population
Ratio
for
Milwaukee
Outbreak
The
national
mortality
rate
for
Acquired
Immune
Deficiency
Syndrome
(
AIDS)
patients
due
to
cryptosporidiosis
cannot
be
directly
derived
from
the
data
collected
during
the
Milwaukee
outbreak,
but
Economic
Analysis
for
the
LT2ESWTR
Proposal
C­
2
June
2003
these
data
can
be
adjusted
to
more
accurately
estimate
mortality
rates
in
2000.
One
adjustment
is
needed
because
there
are
considerably
fewer
AIDS
patients
in
Milwaukee
and
the
State
of
Wisconsin
as
compared
to
the
rest
of
the
country.
As
an
illustration,
in
1993
there
were
about
three
times
the
number
of
persons
living
with
AIDS
per
capita
in
the
United
States
compared
to
Wisconsin.
United
States
population
living
with
AIDS
in
1993
was
132,686
(
CDC
1993)
in
a
total
population
of
257,783,000
(
U.
S.
Census
Bureau,
2001c)
compared
to
Wisconsin's
862
persons
living
with
AIDS
(
CDC
1993)
in
a
total
population
of
5,044,318
(
U.
S.
Census
Bureau,
2001c).
A
second
adjustment
is
necessary
to
reflect
the
increased
incidence
of
AIDS
in
the
United
States
between
1993
and
1999
(
which
is
the
data
used
in
this
EA).
A
further
adjustment
was
needed
to
reflect
the
different
incident
rates
in
areas
served
by
filtered
and
unfiltered
systems.
For
all
these
adjustments,
the
analysis
uses
data
on
the
incidence
of
AIDS
from
the
CDC
and
the
U.
S.
Census
Bureau.
Using
these
two
sources
allows
the
most
consistent
comparisons
across
geographic
areas
and
time.

There
are
various
other
sources
that
were
not
used
that
provide
related
data.
For
example,
Frisby
et
al.
(
1997)
mention
that
approximately
1,300
people
were
living
HIV
in
Milwaukee
in
1993,
but
not
all
HIV
patients
are
immunocompromised
to
the
same
degree
as
AIDS
patients
and,
therefore,
do
not
have
the
same
risk
of
illness
and
death.
Dr.
Neil
Hoxie,
of
the
Bureau
of
Public
Health
in
Wisconsin,
in
personal
communications
estimated
that
1,203
people
were
probably
living
with
AIDS
in
the
metropolitan
statistical
area
of
Milwaukee
in
1993,
an
estimate
higher
than
the
CDC
estimate
for
States.
Unfortunately
no
source
reported
a
count
of
AIDS
patients
within
the
area
served
by
the
Milwaukee
public
water
system,
or
the
area
corresponding
to
the
1993
Cryptosporidium
outbreak.
Using
statewide
numbers
for
the
number
of
people
living
with
AIDS
would
be
certain
to
capture
the
area
of
the
1993
outbreak,
but
would
be
a
likely
underestimate
due
to
rural
populations
with
few
AIDS
patients
being
added
to
the
total
population.
However,
an
estimate
without
all
AIDS
patients
in
the
original
outbreak
area
would
also
be
an
overestimate.
In
the
face
of
this
lack
of
data
related
specifically
to
the
population
affected
by
the
outbreak,
and
a
preference
for
comparable
data
for
multiple
years
in
several
geographic
locations,
the
analysis
uses
data
from
the
CDC
and
the
U.
S.
Census.

C.
3
Derivation
of
Filtered
and
Unfiltered
Population
Numbers
for
Mortality
The
greater
presence
of
sensitive
subpopulations
in
some
areas
might
indicate
a
higher
rate
of
mortality
due
to
cryptosporidiosis.
A
number
of
large
metropolitan
areas
are
served
by
water
systems
that
are
unfiltered
and
the
populations
of
immunocompromised
served
by
unfiltered
systems
differs
from
those
served
by
filtered
systems.
The
analysis
in
Chapter
5,
therefore,
calculates
mortality
rates
for
filtered
and
unfiltered
systems
separately
to
highlight
possible
differences
in
mortality
rates
due
to
cryptosporidiosis.

The
analysis
seeks
to
compare
the
percentage
of
the
total
U.
S.
population
living
with
AIDS
that
live
in
areas
served
by
unfiltered
systems
versus
filtered
systems.
The
CDC,
in
their
semiannual
"
HIV/
AIDS
Surveillance
Report,"
give
the
number
of
individuals
living
with
AIDS
by
metropolitan
statistical
area.
Population
data
from
the
metropolitan
statistical
areas
served
by
the
unfiltered
systems
was
used
instead
of
the
population
served
by
unfiltered
systems.
The
population
count
data
from
the
2000
Census
were
used
because
they
were
more
accurate
than
1999
estimates
of
population.
These
data
are
used
to
develop
adjustment
factors,
and
so
it
was
judged
more
accurate
to
use
inputs
from
consistent
sources,
rather
than
mix
in
service
population
data
that
were
self­
reported
by
utilities.
Data
for
the
relevant
metropolitan
areas
are
shown

For
the
purposes
of
developing
an
adjustment
factor,
the
population
remaining
in
the
U.
S.
is
considered
to
be
served
by
filtered
systems.
The
total
population
within
the
metropolitan
statistical
areas
of
the
unfiltered
systems
was
subtracted
from
the
total
U.
S.
population
in
2000
to
give
an
"
adjusted"
population
for
filtered
systems,
and
the
AIDS
population
of
unfiltered
systems
was
also
subtracted
from
the
national
estimates
of
people
living
with
AIDS.
From
these
numbers,
the
percentage
of
AIDS
patients
in
unfiltered
and
filtered
systems
can
be
determined
(
Exhibit
C.
2).
The
use
of
overall
U.
S.
Census
data
is
appropriate
because
the
incidence
rate
is
therefore
derived
from
the
number
of
persons
living
with
AIDS
and
the
population
of
which
they
are
a
part.
It
would
be
inappropriate
to
derive
a
factor
based
on
the
population
served
by
public
water
systems
because
there
are
no
comparable
estimates
for
the
number
of
people
living
with
AIDS
in
that
population.

The

as

in
Exhibit

are
applied
to
the

in
two

First,
these

are
a
key
input
to
the

that
determines
the

factors
applied

The
results
of
these
calculations
are
presented
in
section
C.
7
and
in
Exhibit
5.22.
Second,
the
data
in
Exhibit
C.

are
used
to
compute
the

in
the

and
those

Introduction
This
appendix
presents
detailed
calculations
and
cost
tables
for
activities
associated
with
LT2ESWTR
implementation
and
monitoring
for
bin
classification
for
three
of
the
four
regulatory
alternatives
(
Alternative
A1
is
not
discussed
because
it
requires
all
plants
to
implement
2
additional
log
of
Cryptosporidium
treatment
and
thus
has
no
bin
classification
monitoring
requirements).
Costs
for
all
activities
are
estimated
as
one­
time
costs.
This
appendix
supports
the
discussion
of
the
rule
activities
in
Chapter
6.
Each
set
of
activities
is
detailed
separately
in
subsequent
sections.

EPA
evaluated
the
ICR,
ICRSSM,
and
the
ICRSSL
modeled
Cryptosporidium
occurrence
distributions
to
estimate
the
percentage
of
plants
that
would
fall
into
any
treatment
bin
and
assumed
that
this
percentage
of
small
plants
would
be
triggered
to
conduct
Cryptosporidium
monitoring.
The
three
modeled
occurrence
distributions
are
used
in
this
appendix
to
establish
a
range
of
possible
costs
for
Cryptosporidium
monitoring.

D.

Baseline
Number
of
Systems
and
Plants
Implementation
Implementation
costs
are
based
on
the
number
of
PWSs
that
have
to
read
and
understand
the
rule
and
include
all
nonpurchased
systems,
including
filtered
and
unfiltered
systems.
Purchased
systems,
because
they
are
assumed
to
not
directly
treat
any
source
water,
are
not
expected
to
have
any
implementation
costs,
although
these
and
other
costs
will
be
passed
on
to
them
in
the
form
of
higher
water
rates.

Source
Water
Monitoring
for
Bin
Classification
Source
water
monitoring
costs
are
structured
on
a
per
plant
basis.
Also,
as
with
implementation
activities,
purchased
plants
are
assumed
not
to
treat
source
water
and
will
not
have
any
monitoring
costs.
There
are
three
types
of
monitoring
that
plants
may
be
required
to
conduct
 
turbidity,
E.
coli,
and
Cryptosporidium.
Source
water
turbidity
is
a
common
water
quality
parameter
used
for
plant
operational
control.
Also,
to
meet
SWTR,
LT1ESWTR,
and
IESWTR
requirements,
most
water
systems
have
turbidity
analytical
equipment
in­
house
and
operators
experienced
with
turbidity
measurement.
Thus,
EPA
assumes
that
the
incremental
turbidity
monitoring
burden
associated
with
the
LT2ESWTR
is
negligible
(
turbidity
is
not
evaluated
in
this
appendix).

All
nonpurchased
plants
in
large
and
medium
systems
are
required
to
conduct
E.
coli
and
Cryptosporidium
monitoring
for
bin
classification
with
two
exceptions:

°
Plants
that
achieve
5.5
log
of
Cryptosporidium
reduction
are
exempt
from
all
monitoring
requirements
(
estimates
of
plants
that
meet
this
criteria
are
presented
in
the
baseline
for
filtered
and
unfiltered
plants
in
Chapter
4).

°
Plants
that
have
2
years
of
historical
Cryptosporidium
data
that
are
equivalent
in
sample
number,
frequency,
and
data
quality
(
e.
g.,
volume
analyzed,
percent
recovery)
to
data
that
would
be
collected
under
the
LT2ESWTR
with
EPA
Method
1622/
23
are
exempt
from
all
monitoring
requirements
(
for
costing
purposes,
EPA
assumes
that
the
number
of
plants
able
to
provide
historical
data
to
meet
the
requirements
above
is
negligible).

Plants
in
small
systems
will
be
required
to
conduct
1
year
of
semi­
monthly
E.
coli
source
water
monitoring
for
bin
classification,
with
the
exception
of
plants
achieving
5.5
log
of
Cryptosporidium
reduction
(
as
presented
in
Chapter
4).
These
small
plants
will
have
to
monitor
for
Cryptosporidium
only
if
E.
coli
monitoring
results
exceed
the
following
levels:

°
annual
mean
>
10
E.
coli/
100
ml
for
lakes
and
reservoirs
°
annual
mean
>
50
E.
coli/
100
ml
for
flowing
streams
Cryptosporidium
monitoring
may
be
comprised
of
1
year
of
semi­
monthly
samples
or
2
years
of
monthly
samples.

Rule
Implementation
Activities
This
section
presents
the
costs
for
systems
and
States/
Primacy
Agencies
to
perform
implementation
activities
associated
with
the
LT2ESWTR.
Activities
performed
by
PWSs
include
reading
and
understanding
the
rule
and
training
employees
on
rule
requirements.
The
number
of
systems
that
must
conduct
implementation
activities
is
the
same
for
all
occurrence
distributions.
State
implementation
activities
include
regulation
adoption
and
program
development,
training
State/
Primacy
Agency
staff,
training
PWS
staff
and
providing
technical
assistance,
and
updating
the
data
management
systems.
The
cost
and
burden
incurred
as
part
of
rule
implementation
are
not
expected
to
vary
for
the
different
regulatory
alternatives.

Assumptions
and
cost
estimates
for
rule
implementation
activities
are

Monitoring
Activities
for
Initial
Bin
Classification
The
purpose
of
bin
classification
is
to
determine
what
level
of
Cryptosporidium
reduction
will
be
required.
Bin
classification
is
determined
by
source
water
Cryptosporidium
monitoring.

Monitoring
costs
for
plants
include
the
labor
costs
associated
with
collecting
E.
coli
and
Cryptosporidium
samples,
the
laboratory
costs
of
shipping
and
analyzing
the
samples,
and
costs
for
reporting
results
to
the
State/
Primacy
Agency
(
as
noted
in
section
D.
2,
costs
associated
with
turbidity
monitoring
are
assumed
to
be
negligible).
State
costs
for
analyzing
PWS
reports,
responding
to
PWSs,
and
recordkeeping
are
also
included
in
the
bin
classification
monitoring
costs.
Cost
estimates
for
each
type
of
monitoring
are
described
in
detail
in
this
section.

D.
4.1
E.
coli
Monitoring
Number
of
Samples
Under
Alternatives
A2
through
A4,
small
plants
are
required
to
sample
source
water
biweekly
for
one
year
for
E.
coli
(
26
total
samples).
Under
the
same
regulatory
alternatives,
large
and
medium
plants
will
carry
out
monitoring
on
a
predetermined
schedule
for
24
months.
The
number
of
samples
is
based
on
one
of
two
monitoring
scenarios:

°
Highest
12­
month
running
annual
average
(
RAA)
if
monthly
samples
are
taken
(
24
samples
total)

°
Two­
year
mean
if
plant
conducts
twice
per
month
monitoring
for
24
months
(
48
samples
total)

EPA
estimates
that
most
large
and
medium
plants
will
use
the
maximum
RAA
for
bin
classification
because
it
requires
fewer
samples.
Therefore,
this
analysis
assumes
no
monitoring
costs
for
the
two­
year
mean
option.

Laboratory
Costs
Systems
may
analyze
their
samples
in­
house
if
they
have
the
equipment
to
do
so,
or
they
may
send
the
samples
to
a
commercial
laboratory.
EPA
estimates
the
cost
per
sample
in­
house
is
$
21.00
(
DynCorp
2000)),
and
to
ship
the
sample
to
a
commercial
laboratory
costs
$
70
(
includes
shipping
and
commercial
analysis)
(
DynCorp
2002).
The
average
cost
per
sample
for
various
system
sizes
reflects
the
estimate
of
the
percentage
of
plants
that
will
do
in­
house
versus
commercial
analysis.
The
total
laboratory
cost
of
an
E.
coli
sample
($
57.75
for
small
plants,
$
33.25
for
medium
plants,
and
$
21.00
for
large
plants)
takes
into
account
the
percentage
of
systems
with
E.
coli
analysis
capabilities.
For
those
that
do
not
have
in­
house
capabilities,
overnight
shipping
costs
(
based
on
FedEx
rates)
have
been
added
to
the
laboratory
fee.
The
estimate
of
plants
with
in­
house
analytical
capabilities
for
E.
coli
was
generated
using
the
Baseline
Handbook.
Total
laboratory
costs
for
E.
coli
monitoring
are
summarized
in
Exhibit
D.
12
for
each
population
size
category
of
CWSs,
NTNCWSs,
and
TNCWSs,
respectively.
The
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions
do
not
affect
the
number
of
plants
monitoring
for
E.
coli.

Labor
Costs
In
addition
to
the
laboratory
costs
for
E.
coli
monitoring,
labor
will
be
required
for
plant
employees
to
take
the
samples.

Sampling
points
are
at
the
source
water
intake;
therefore,
each
sample
was
estimated
to
take
15
minutes.
A
technical
labor
rate
($
24.96
per
hour
for
all
systems)
is
assumed
for
E.
coli
monitoring
(
BLS
2001).
Total
labor
costs
per
plant
were
estimated
by
multiplying
the
minutes
required
per
sample
(
converted
into
hours),
the
number
of
samples
per
plant
per
year,
and
the
labor
rate
per
hour.
Total
labor
costs
for
E.
coli
monitoring
are
summarized
in
Exhibit
D.
12
for
CWSs,
NTNCWSs,
and
TNCWSs,
respectively.
Once
again,
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions
do
not
affect
the
number
of
plants
that
have
to
monitor
for
E.
coli.

Cryptosporidium
Monitoring
Number
of
Samples
Small
plants
that
are
triggered
into
Cryptosporidium
monitoring
based
on
E.
coli
monitoring
results
(
see
section
D.
2)
will
be
required
to
collect
and
analyze
24
source
water
Cryptosporidium
samples
over
1
year.
For
costing
purposes,
EPA
assumes
that
small
plants
will
collect
24
samples
and
bin
assignment
will
be
based
on
the
average
concentration
of
all
samples.
Large
and
medium
plants
will
carry
out
Cryptosporidium
monitoring
similar
to
E.
coli
monitoring
on
a
predetermined
schedule
for
24
months.

For
all
plant
sizes,
EPA
assumes
two
additional
matrix
spike
samples
will
be
collected
during
the
monitoring
period.

Although
the
sampling
requirements
for
plants
required
to
monitor
Cryptosporidium
are
the
same
for
Alternatives
A2
through
A4,
the
number
of
plants
triggered
to
monitor
will
vary
for
each
regulatory
alternative.

Laboratory
Costs
The
total
cost
of
laboratory
analysis
of
a
Cryptosporidium
sample
($
529.50)
is
the
sum
of
the
laboratory
costs,
the
shipping
costs,
and
analysis
of
multiple
subsamples.

The
laboratory
cost
for
Cryptosporidium
analysis
($
403.00)
was
estimated
in
an
analysis
by
Dyncorp
(
2000).
This
estimate
assumes
that
the
laboratory
filters
the
sample,
so
the
PWS
ships
the
entire
10­
liter
sample.
A
shipping
cost
($
88.70,
based
on
FedEx
rates)
is
added,
assuming
that
all
plants
must
ship
samples
overnight
to
private
laboratories
for
analysis.
Samples
must
be
divided
into
subsamples
for
analysis
if
they
have
a
pellet
size
greater
than
0.5
ml.
The
proportion
of
samples
being
subdivided
is
based
on
results
of
the
Supplemental
Surveys.
Laboratory
and
shipping
costs
per
plant
are
summarized
in
Exhibits
D.
13
through
D15.

Total
laboratory
costs
for
Alternative
A2
are
shown
in
Exhibits
D.
13a
to
D.
13c.
The
costs
for
Alternative
A2
for
each
system
type
are
identical
for
the
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions
because
under
Alternative
A2,
all
small
plants
are
assumed
to
be
triggered
into
Cryptosporidium
monitoring
based
on
E.
coli
monitoring
results.
Because
the
cutoff
level
for
the
first
bin
under
Alternative
A2
is
less
than
half
the
Cryptosporidium
concentration
cutoff
for
Bin
1
under
Alternative
A3,
the
E.
coli
trigger
level
would
presumably
also
be
much
lower
under
Alternative
A2.
EPA
estimated
that
these
levels
would
be
so
low
that
all
small
plants
would
be
triggered
into
Cryptosporidium
monitoring.

Total
laboratory
costs
for
Cryptosporidium
monitoring
are
summarized
in
Exhibits
D.
14a
through
D.
14c
for
each
population
size
category
of
CWSs,
NTNCWSs,
and
TNCWSs,
based
on
the
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions,
respectively,
for
Alternative
A3.
Total
laboratory
Cryptosporidium
analysis
costs
range
from
approximately
$
42.8
million
(
based
on
the
ICRSSL)
to
$
51.6
million
(
based
on
the
ICR).

based
on
the

respectively,
for

Total
laboratory
Cryptosporidium

range
from
approximately
$
58.7
million
(
based
on
the
ICRSSL)
to
$
61.1
million
(
based
on
the
ICR).

Labor
Costs
In
addition
to
the
laboratory
costs
for
Cryptosporidium
monitoring,
labor
will
be
required
for
plant
employees
to
take
samples.
Samples
are
required
at
the
source
water
intake.
Collecting
a
sample
was
estimated
to
take
30
minutes,
slightly
higher
than
the
time
assumed
for
E.
coli
samples,
because
of
the
larger
volume
required.
A
technical
labor
rate
($
24.96
per
hour
for
all
system
sizes)
was
assumed
for
Cryptosporidium
monitoring.
Labor
costs
per
plant
were
estimated
by
multiplying
the
number
of
hours
per
sample,
the
number
of
samples
per
plant
per
year,
and
the
labor
rate
per
hour.
These
costs
and
total
costs
are
shown
in
Exhibit
D.
13
through
D.
15,
based
on
the
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions
for
Alternatives
A2
through
A4,
respectively.
The
labor
costs
for
each
system
type
are
identical
for
the
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions
for
Alternative
A2
because
under
that
regulatory
alternative,
all
plants
are
required
to
monitor
Cryptosporidium.

Reporting
Costs
For
medium
and
large
systems,
EPA
will
collect
data
directly
from
the
approved
laboratories
on
an
ongoing
basis
(
i.
e.,
as
data
are
generated
they
will
be
entered
by
laboratories
into
an
EPA
database).
However,
medium
and
large
systems
will
still
review
the
data.
At
the
end
of
the
2­
year
monitoring
period,
EPA
will
give
the
results
of
the
monitoring
to
the
States/

Agencies,
which
will
work
with
their
systems
to
determine
appropriate
compliance
steps.

Because
small
system
monitoring
is
expected
to
occur
after
States
achieve
primacy,
EPA
assumes
that
small
plants
will
report
monitoring
results
to
their
State/
Primacy
Agency.
Costs
associated
with
reporting
would
include
the
amount
of
time
it
takes
for
a
plant
to
gather
monitoring
information
and
submit
it
to
their
State/
Primacy
Agency
for
review.
Since
the
exact
schedule
of
reporting
to
States
is
not
set
in
the
rule,
there
may
be
some
variation
in
reporting
effort
from
State
to
State.

For
this
analysis,
0.25
hours
per
sample
(
6.5
hours
for
small
plants
and
6
hours
for
medium
and
large
plants)
is
used
to
estimate
costs.

Reporting
costs
for
small
plants
serving
up
to
500
people
are
based
on
the
full
technical
rate
($
24.96
per
hour).
For
those
plants
serving
more
than
500
people,
costs
are
based
on
an
80/
20
percent
split
between
technical
and
managerial
labor
rates
(
the
split
was
between
$
24.96
per
hour
and
$
44.91
per
hour)
(
BLS
2001).
The
costs
of
reporting
are
presented
in
Exhibit
D.
16
for
CWSs,
NTNCWSs,
and
TNCWSs,
respectively.
The
number
of
plants
reporting
is
the
same
for
the
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions.

for
States/

Agencies
States/
Primacy
Agencies
will
incur
costs
as
a
result
of
the
small
system
E.
coli
and
Cryptosporidium
monitoring.
To
estimate
State/
Primacy
Agency
costs,
the
number
of
FTEs
required
per
activity
is
multiplied
by
the
number
of
labor
hours
per
FTE,
the
State/
Primacy
Agency
labor
hour
cost,
and
the
number
of
States
and
Territories.

The
number
of
FTEs
required
per
activity
was
estimated
by
EPA
based
on
similar
rules.
States/
Primacy
Agencies
are
expected
to
work
with
the
small
systems
conducting
monitoring
to
review
data
and
make
bin
classification
determinations.
State/
Primacy
Agency
activities
include:

°
Analyzing
monitoring
reports
and
determining
bin
classification
 
0.3
FTEs
for
initial
E.
coli
monitoring,
0.2
FTEs
for
initial
Cryptosporidium
monitoring
and
future
E.
coli
monitoring,
and
0.1
FTEs
for
future
Cryptosporidium
monitoring.

°
Consultation
with
PWSs
 
same
number
of
FTEs
as
for
analyzing
monitoring
reports
and
determining
bin
classification.

°
Conducting
recordkeeping
 
0.25
FTEs.

State/
Primacy
Agency
labor
rates,
as
stated
in
Chapter
6,
section
6.1.1,
are
$
28.89.
The
number
of
States
and
Territories
is
estimated
as
the
sum
of
the
50
States
in
the
United
States,
6
Territories,
and
1
Indian
Tribe.
EPA
estimates
the
national
total
monitoring
cost
for
States/
Primacy
Agencies
to
be
$
10.4
million
for
initial
and
future
monitoring
combined.
State
costs
are
expected
to
be
minimal
during
the
initial
phase
of
monitoring
for
large
and
medium
systems
because
EPA
will
be
analyzing
the
data.

Technology
Compliance
Reporting
for
Plants
In
order
to
get
log
removal
credit
for
Cryptosporidium,
PWSs
will
be
required
to
demonstrate
that
they
are
complying
with
design
and
operational
criteria
for
any
new
toolbox
technologies
they
install.
For
some
technologies
the
demonstration
of
compliance
will
be
similar
to
that
required
for
existing
technologies,
and
no
additional
burden
will
be
incurred.
For
instance,
the
combined
filter
performance
toolbox
option
requires
monitoring
of
turbidity
of
the
effluent
from
each
filter;
systems
are
already
required
to
do
the
same
monitoring
under
the
IESWTR
and
the
LT1ESWTR.
No
new
burden
is
assumed
for
these
systems.
Other
technologies
are
assumed
to
be
implemented
by
few
systems
(
based
on
technology
distributions
modeled
for
the
LT2ESWTR
EA),
so
burden
for
demonstrating
compliance
for
them
is
negligible.
Few
systems,
for
example,
are
expected
to
implement
watershed
control
programs
for
log
removal
credit.

The
labor
for
filtered
plants
for
each
regulatory
alternative
and
occurrence
distribution
is
shown
in
Exhibits
D.
21
through
D.
23.
For
filtered
plants,
new
burden
is
predicted
to
be
incurred
only
by
systems
switching
to
UV,
microfiltration/
ultrafiltration,
and
bank
filtration.

For
unfiltered
plants,
reporting
costs
are
predicted
to
be
incurred
only
by
systems
(
CWSs
only)
installing
UV
or
ozone
for
disinfection
(
on
top
of
their
existing
disinfectants).
No
unfiltered
plants
are
predicted
to
add
chlorine
dioxide
disinfection.
The
reporting
costs
for
unfiltered
plants
are
shown
in
D.
24.
There
is
only
one
exhibit
for
unfiltered
plants
because
they
have
only
one
regulatory
alternative
and
one
occurrence
distribution
(
for
the
ICR).

Reporting
costs
for
small
plants
serving
up
to
500
people
are
based
on
the
full
technical
rate
($
24.96
per
hour).
For
those
plants
serving
more
than
500
people,
costs
are
based
on
an
80/
20
percent
split
between
technical
and
managerial
labor
rates
(
the
split
was
between
$
24.96
per
hour
and
$
44.91
per
hour)
(
BLS
2001).

The
reporting
and
recordkeeping
burden
for
each
plant
is
assumed
to
be
3
hours
per
month,
or
36
hours
per
year.

Disinfection
Benchmarking
D.
6.1
Disinfection
Benchmarking
for
PWSs
PWSs
of
all
sizes
that
conduct
Cryptosporidium
monitoring
will
be
required
to
apply
for
approval
of
existing
inactivation
benchmarks,
to
calculate
a
benchmark
based
on
existing
profiling
data,
or
to
conduct
inactivation
profiling.
Some
small
PWSs
that
do
not
have
to
monitor
Cryptosporidium
may
also
have
to
conduct
inactivation
profiling
if
their
trihalomethane
or
haloacetic
acid
levels
exceed
certain
limits.
Most
plants
will
already
have
existing
benchmarks
due
to
similar
requirements
under
the
IESWTR
and
LT1ESWTR.
If
they
do
not,
they
should
be
able
to
calculate
benchmarks
based
on
existing
operational
data
collected
as
part
of
the
Surface
Water
Treatment
Rule
requirements.
Most
of
these
plants
need
to
maintain
these
data
onsite,
but
do
not
need
to
report
them.
The
burden
for
this
is
assumed
to
be
negligible.

Plants
that
wish
to
make
a
major
change
to
their
disinfection
process
need
to
compile
and
submit
their
disinfection
profile
and
benchmark
to
their
States
and
consult
with
their
States
about
the
change.
Only
plants
that
are
predicted
to
change
technologies
as
a
result
of
bin
classification
are
assumed
to
submit
their
disinfection
profile.
The
burden
for
this
is
estimated
to
be
4
hours
per
plant
and
is
shown
in
Exhibits
D.
25
through
D.
27.

Reporting
costs
for
small
plants
serving
up
to
500
people
are
based
on
the
full
technical
rate
($
24.96
per
hour).
For
those
plants
serving
more
than
500
people,
costs
are
based
on
an
80/
20
percent
split
between
technical
and
managerial
labor
rates
(
the
split
was
between
$
24.96
per
hour
and
$
44.91
per
hour)
(
BLS
2001).

Future
Monitoring
for
Bin
Reclassification
Six
years
after
initial
binning,
systems
will
be
required
to
undergo
another
round
of
monitoring
to
determine
if
their
source
water
quality
has
changed,
thus
changing
the
required
treatment.
Lacking
better
information,
EPA
assumed
that
costs
are
the
same
as
the
costs
for
the
initial
monitoring
round.
The
number
of
plants
did
change,
however,
as
plants
which
achieved
5.5
log
treatment
to
comply
with
the
LT2ESWTR
were
omitted
from
the
second
round
of
monitoring.

Future
Monitoring
Reporting
Labor
and
cost
of
labor
for
future
monitoring
are
assumed
to
be
the
same
as
for
initial
monitoring,
although
for
future
monitoring,
all
systems
are
expected
to
report
their
results
to
their
Primacy
Agencies
rather
than
to
EPA.
The
number
of
systems
monitoring,
however,
will
be
lower
than
for
initial
monitoring,
since
some
plants
are
expected
to
have
implemented
treatment
that
exempts
them
from
future
monitoring.

Costs
associated
with
reporting
would
include
the
amount
of
time
it
takes
for
a
plant
to
gather
monitoring
information
and
submit
it
to
its
State/
Primacy
Agency
for
review.
Since
the
exact
schedule
of
reporting
to
States
is
not
set
in
the
rule,
there
may
be
some
variation
in
reporting
effort
from
State
to
State.
For
this
analysis,
0.25
hours
per
sample
(
6.5
hours
for
small
plants
and
6
hours
for
medium
and
large
systems)
is
used
to
estimate
costs.

Reporting
costs
for
small
plants
serving
up
to
500
people
are
based
on
the
full
technical
rate
($
24.96
per
hour).
For
those
plants
serving
more
than
500
people,
costs
are
based
on
an
80/
20
percent
split
between
technical
and
managerial
labor
rates
(
the
split
was
between
$
24.96
per
hour
and
$
44.91
per
hour)
(
BLS
2001).
The
costs
of
reporting
are
presented
in
Exhibit
D.
37
to
D.
39
for
Alternatives
A2
to
A4,
respectively.
The
number
of
systems
reporting
also
varies
with
the
use
of
the
ICR,
ICRSSM,
and
ICRSSL
occurrence
distributions.
This
is
because
future
monitoring
and
reporting
depends
on
the
number
of
systems

Exhibit

constraints
and
design
criteria)
considered
for
surface
and
ground
water
under
the
direct
influence
plants
to
meet
the
LT2ESWTR.
This
appendix
builds
on
information
presented
in
Chapter
6
by
presenting:

°
Capital
unit
cost
estimates
for
a
wide
range
of
design
flows
(
in
tabular
and
graphical
forms)

°
Operations
and
maintenance
(
O&
M)
unit
cost
estimates
for
a
wide
range
of
average
daily
flows
(
in
tabular
and
graphical
forms)

The
costs
are
from
the
"
Technologies
and
Costs
Document
for
Control
of
Microbial
Contaminants
and
Disinfection
By­
Products"
(
T&
C
document)
(
USEPA
2003a).
These
unit
costs
have
been
revised
to
incorporate
recommendations
from
the
National
Drinking
Water
Advisory
Council
(
NDWAC)
Arsenic
Cost
Working
Group
(
National
Drinking
Water
Advisory
Council
2001).
The
costs
are
given
over
a
wide
range
of
design
flows
from
7,000
gallons
per
day
to
520
million
gallons
per
day
(
MGD),
representative
of
the
flow
range
experienced
by
water
systems.

The
T&
C
provides
costs
at
16
flows
covering
the
above
range
for
each
technology.
However,
the
EA
cost
model
initially
uses
nine
size
categories
that
do
not
match
any
of
the
16
flows.
Linear
interpolation
between
each
of
the
16
points
is
used
to
generate
unit
costs
for
the
nine
size
categories.
If
an
EA
size
category
correlated
to
a
flow
lower
than
the
minimum
flow
in
the
T&
C
document,
the
cost
at
the
minimum
flow
was
used.
If
an
EA
size
category
exceeded
the
maximum
flow,
the
costs
were
extrapolated
linearly
with
the
same
slope
as
given
between
the
highest
two
points.

The
following
table
lists
the
exhibits
in
this
appendix.
Each
exhibit
lists
the
constraints
and
design
criteria
for
the
technology
and
presents
a
table
showing
the
unit
cost
estimates
for
each
design
or
average
flow
point.
The
graph
displays
each
point
connected
by
a
line;
the
unit
costs
calculated
for
the
EA
cost
model
fall
on
these
lines.
All
graphs
are
in
log­
log
scale.

Introduction
This
appendix
describes
the
methodology
used
in
estimating
the
technologies
that
plants
are
most
likely
to
select
to
meet
the
requirements
of
the
LT2ESWTR.
This
estimate
is
known
as
the
technology
selection
forecast.
Separate
technology
selection
forecasts
are
developed
for
filtered
plants,
unfiltered
plants,
and
uncovered
finished
water
reservoirs.
This
appendix
specifically
deals
with
the
technology
selection
forecasts
for
filtered
plants.
Technology
selections
for
unfiltered
plants
and
uncovered
finished
water
reservoirs
are
more
straightforward
and
are
summarized
in
Chapter
6.
The
remainder
of
this

The
technology
selection
forecast
for
filtered
surface
water
and
GWUDI
plants
depends
on
Cryptosporidium
reduction
requirements.
The
reduction
required
under
the
LT2ESWTR
is
a
function
of
each
plant's
source
water
Cryptosporidium
monitoring
results
and
consequent
bin
classification.
Treatment
requirements
for
each
bin
are
summarized
in
Chapter
2
of
this
EA.
In
addition
to
the
three
action
bins
laid
out
by
the
regulation,
two
other
bins
are
created
for
purposes
of
the
technology
selection
analysis.
These
bins
take
into
account
the
0.5

plants
will
get
for
existing

(
0.15

A
more
detailed
discussion
of
this
binning
is
included
in
Chapter

and
Appendix

Technologies
Available
to
Meet
Bin
Requirements
The
LT2ESWTR
employs
a
toolbox
approach
for
meeting
action
bin
requirements.
The
"
microbial
toolbox"
contains
various
Cryptosporidium
reduction
strategies
for
which
plants
can
receive
"
credit"
(
or
a
range
of
credit)
to
meet
treatment
requirements
for
a
given
bin.
Components
of
the
microbial
toolbox
cover
a
wide
array
of
management
strategies
including
watershed
control,
selecting
an
alternative
source,
pretreatment,
improved
treatment,
improved
disinfection,
peer
review,
and
other
plant
demonstration
strategies.
Exhibit
2.2
in
Chapter
2
lists
each
toolbox
component
and
its
corresponding
log
credit
or
range
of
log
credits.

Many
toolbox
components,
such
as
peer
review
and
selecting
an
alternative
source,
are
not
included
in
this
technology
selection
forecast
because
of
the
lack
of
data
on
appropriate

and

usage
by
plants.
Also,
some
technologies
are
not
considered
feasible
for
small
and
very
small
systems
because
of
operational
constraints.
Technologies
may
be
selected
alone
or
in
combination
to
achieve
the
required
log
credit.
The
log
credits
are
based
on
the
minimum
removal
that
the
technology
is
expected
to
achieve
with
proper
design
and
implementation.
Systems
could
potentially
receive
higher
log
credits
through
performance
demonstration
studies.

Technology
Selection
Forecast
Methodology
The
overall
methodology
used
to
develop
the
technology
selection
forecast
for
each
action
bin
and
size
category
relies
on
a
"
least­
cost
decision
tree."
In
other
words,
for
estimating
the
economic
cost
of
the
rule
requirements,
it
assumes
that
drinking
water
plants
will
select
the
least
expensive
technology
or
combination
of
technologies
available
to
meet
the
log
removal
requirements
of
a
given
action
bin.
Technology
selection
forecasts
are
estimated
separately
for
the
following
size
classifications:
very
small,
small,
medium,
and
large
systems.

The
least­
cost
decision
tree
uses
relative
cost
ratios
to
rank
the
technologies
by
cost.
The
relative
cost
ratios
shown
in
column
two
of
Exhibits
F.
3
 
F.
18
are
equal
to
the
total
annual
cost
of
a
given
technology
divided
by
the
total
annual
cost
of
the
cheapest
technology.
Assumptions
used
to
calculate
total
annual
costs
are
summarized
in
Chapter
6.

The
relative
cost
ratios
for
various
technologies
change
with
size
because
technologies
have
different
economies
of
scale
associated
with
them
and
different
applicability
to
different
flow
ranges.
Therefore,
the
relative
cost
ratios
must
be
evaluated
separately
for
each
of
the
four
size
classifications.
Because
total
annual
costs
are
calculated
for
nine
individual
system
size
categories,
but
forecasts
are
made
according
to
four
aggregated
categories,
relative
costs
are
calculated
using
the
weighted
average
costs.
Within
a
given
size
category
the
relative
costs
are
determined
by
multiplying
the
costs
for
that
category
by
the
number
of
plants
in
that
category
divided
by
all
the
plants
in
that
classification.
For
example,
costs
for
the
medium­
sized
systems
are
calculated
by
multiplying
the
unit
costs
for
the
M1
category
by
the
number
of
plants
in
the
M1
category
plus
the
unit
costs
for
the
M2
category
times
the
number
of
plants
in
the
M2
category
and
dividing
the
sum
by
the
total
number
of
medium­
sized
plants.

Technology
selections
within
the
least­
cost
decision
tree
are
limited
by
predicted
"
maximum
use
percentages."
These
are
limits
on
the
percent
of
plants
that
may
select
a
particular
technology
to
meet
the
bin
requirements.
Maximum
use
percentages
recognize
the
following:
not
all
treatment
plants
may
be
able
to
implement
certain
technologies
due
to
site­
specific
constraints
such
as
system
hydraulics,
lack
of
space,
and
source
water
quality;
for
some
technologies,
industry
may
not
have
the
capacity
to
meet
rapid
increases
in
demand;
applicability
of
some
technologies
is
dependent
on
existing
treatment
train
(
e.
g.,
direct
filtration
plants
cannot
receive
credit
for
pre­
sedimentation
and
are
estimated
not
to
be
able
to
achieve
compliance
with
combined
filter
performance).
Finally,
maximum
use
percentages
recognize
special
operational
constraints
for
very
small
and
small
systems,
as
identified
through
an
expert
opinion
process
for
the

2

and
Disinfection

forecast.
For
example,
chlorine
dioxide
and
ozone
are
not
considered
viable
technologies
for
systems
serving
fewer
than
500
people.
Very
small
systems
are
assumed
to
select
only
bag/
cartridge
filters,
ultraviolet
(
UV),
and
microfiltration/
ultrafiltration
(
MF/
UF).

The
maximum
use
percentages
for
combination
technologies
are
the
product
of
the
maximum
use
percentages
for
the
individual
technologies.
The
product
is
used
because
the
set
of
conditions
that
limit
use
of
one
technology
are
assumed
to
be
independent
of
the
conditions
that
limit
another.
For
instance,
a
plant
that
could
use
chlorine
dioxide
might
not
be
near
a
source
that
would
allow
use
of
in­
bank
filtration.
As
an
example
calculation,
the
maximum
use
percentage
for
combined
filter
performance
(
15
percent)
combined
with
chlorine
dioxide
(
23
percent)
for
large
systems
is
equal
to
3.45
percent
 
15
percent
times
23
percent.

The
maximum
use
percentages
for
chlorine
dioxide
and
ozone
are
determined
using
the
Surface
Water
Analytical
Tool
(
SWAT).
The
SWAT
model
is
used
by
inputting
water
quality
parameters
such
as
pH,
TOC,
and
bromide
along
with
a
given
disinfectant
dose.
SWAT
is
used
to
determine
the
maximum
percentage
of
plants
that
could
use
this
technology
without
violating
Stage
2
requirements
for
chlorite
or
bromate.

In
order
to
evaluate
chlorine
dioxide
using
SWAT,
information
regarding
the
inactivation
of
Cryptosporidium
by
chlorine
dioxide
is
needed.
Since,
final
CT
numbers
are
not
available,
the
recommendation
of
the
Microbial
Subcommittee
of
the
TWG
to
multiply
the
CT
needed
for
the
same
log
inactivation
of
Giardia
by
7.5
was
followed.
Very
little
information
is
available
on
the
ability
of
chlorine
dioxide
to
inactivate
Cryptosporidium.
This
means
that
the
dose
required
for
inactivation
of
Cryptosporidium
is
7.5
times
higher
than
the
dose
needed
to
inactivate
the
same
amount
of
Giardia.
The
microbial
subcommittee
considered
this
value
to
be
optimistic,
but
recommended
its
use
in
order
to
maximize
the
feasibility
of
chlorine
dioxide
applications.
This
recommendation
could
lead
to
an
underestimate
of
national
costs
and
benefits
because,
less
use
of
chlorine
dioxide
would
lead
to
less
production
of
chlorite,
and
more
systems
employing
UV.

Plants
predicted
to
have
toolbox
technologies
installed
prior
to
the
promulgation
of
LT2ESWTR
use
a
separate
set
of
maximum
use
percentages
than
those
plants
without
pre­
LT2
credit.
These
plants
must
be
tracked
separately
because
those
with
existing
toolbox
technologies
cannot
be
allowed
to
select
those
same
technologies.
For
example,
consider
the
maximum
use
percentage
for
combined
filter
performance
for
large
systems.
It
is
assumed
that
overall
80
percent
of
conventional
filtration
plants
can
use
combined
filter
performance
to
achieve
a
reduction
credit.
75
percent
of
all
large
systems
are
conventional
filtration
plants.
58
percent
of
large
plants
receive
a
pre­
LT2
credit,
52
percent
of
them
receive
that
credit
for
combined
filter
performance.
Therefore,
90
percent
(
52/
58)
of
large
plants
with
pre­
LT2
credit
already
achieve
compliance
for
combined
filter
performance
and
would
not
be
able
to
select
that
technology
to
obtain
the
remainder
of
their
required
log
treatment.
Also
because
a
large
percentage
of
conventional
plants
(
52
out
of
75
percent)
receive
the
combined
filter
performance
pre­
LT2ESWTR
credit,
the
remaining
plants
will
disproportionately
use
treatment
processes
other
than
conventional
filtration.
Of
the
remaining
plants
only
48
percent
((
0.75­
0.52)/
0.48)
are
conventional.
These
48
percent
are
assumed
to
be
evenly
distributed
among
the
6
percent
of
plants
that
received
a
pre­
LT2ESWTR
credit
and
the
42
percent
that
did
not.
The
maximum
use
percentage
of
80
percent
of
all
conventional
systems
is
still
assumed.
Therefore
for
plants
receiving
the
pre­
LT2
credit,
the
maximum
use
percentage
is
4%
(
0.1*
0.8*
0.48).
For
plants
not
receiving
the
credit,
the
maximum
use
percentage
is
38
percent
(
0.42*
0.8*
48).

percentages
used
for
the

large
plant
technology
selection
forecasts.
The
percentages
listed
are
limitations
on
the
percent
of
plants
that
may
use
individual
technologies.

A
technology
or
combination
of
technologies
may
only
be
used
if
its
log
credit
is
equal
to
or
greater
than
the
log
action
bin.
The
least
expensive
technology
is
chosen
first
and
the
maximum
use
percentage
is
used
without
any
adjustment.
The
maximum
use
percentage
of
the
second
least
expensive
technology
is
then
multiplied
by
the
difference
of
100
percent
and
the
maximum
use
percentage
of
the
first
technology.
This
process
continues
through
all
the
technologies
until
the
sum
of
the
calculated
percentages
equals
100
percent.
MF/
UF
does
not
have
a
limit
on
its
maximum
use
percentage,
so
any
plants
not
selecting
a
cheaper
technology
are
included
in
this
technology.
If
the
percent
of
plants
selecting
a
particular
technology
or
technology
combination
is
less
than
0.1
percent,
it
is
assumed
to
be
negligible,
and
the
next
technology
is
evaluated.

Exhibit
F.

shows
a
step­
by­
step
example
calculation
of
the
technology
selection
forecast
for
small
systems
in
the
2.0
log
action
bin.
Note
that
combinations
with
technologies
that
have
been
previously
used
in
the
decision
tree
may
not
be
selected.
For
example,
the
first
step
assumes
that
all
plants
that
could
use
cartridge
filters
do
so.
Therefore,
the
option
of
cartridge
filters
plus
chlorine
dioxide
cannot
be
selected,
as
no
plants
remain
that
have
the
capability
of
using
cartridge
filters.
On
the
other
hand,
if
the
technology
selected
first
is
not
a
single
technology
but
a
combination
of
technologies,
other
combinations
that
utilize
that
technology
may
be
possible.
For
example,
in
the
2.5
log
bin,
cartridge
filters
plus
chlorine
dioxide
is
the
cheapest
technology;
12
percent
of
the
plants
would
use
it.
Because
the
maximum
use
percentage
for
cartridge
filters
is
50
percent
and
only
12
percent
have
selected
cartridge
filters,
38
percent
of
the
plants
could
still
select
cartridge
filters.
Therefore,
the
option
of
cartridge
filters
plus
ozone
is
not
ruled
out.

Results
Appendix
G
presents
technology
selection
results
for
filtered
plants.
To
estimate
technology
selections
for
filtered
plants,
a
number
of
conditions
were
used
(
see
Appendix
F
for
a
description
of
the
methodology
for
technology
selection).
Below
is
an
explanation
of
the
abbreviations
used
in
this
appendix,
and
a
brief
explanation
of
each
condition.

Regulatory
Alternatives

All
systems
are
required
to
achieve
a
2.0

for
Cryptosporidium.

A2
A2
is
the
alternative
that
requires
the
most
reduction
of
Cryptosporidium.
Systems
with
0.03­
0.1

Cryptosporidium.
Systems
with
0.1­
1.0
oocysts/
L
must
meet
a
1.5
log,
and
systems
with
greater
than
1.0
oocysts/
L
must
meet
a
2.5
log.

A3
A3
is
the
Preferred
Alternative.
Under
this
option,
systems
that
have
0.075­
1.0
oocysts/

must
achieve
a
1.0

treatment
credit
for
Cryptosporidium.
Systems
with
1.0­
3.0
oocysts/
L
must
achieve
a
2.0
log,
and
systems
with
greater
than
3.0
oocysts/
L
must
meet
a
2.5
log.

A4
A4
is
the
alternative
that
requires
the
least
reduction
of
Cryptosporidium.
Systems
that
have
0.1­
1.0
oocysts/
L
must
achieve
a
0.5
log
treatment
credit
for
Cryptosporidium
and
systems
that
have
greater
than
1.0

Appendix
H
Treatment
Costs
for
Filtered
and
Unfiltered
Plants
Appendix
H
presents
total
costs
of
treatment
for
filtered
and
unfiltered
plants.
The
methodology
for
estimating
these
costs
is
provided
in
Chapter
6
and
supplemented
by
Appendix
A,
Appendix
E,
and
Appendix
F.
Cost
estimates
are
presented
as
present
value,
calculated
with
3
and
7
percent
discount
rates.
See
Appendix
O
for
annualized
costs.

Below
is
an
explanation
of
the
abbreviations
used
in
this
appendix,
and
a
brief
explanation
of
each
condition.

Appendix

Unit
Costs

Uncovered

Water
Reservoirs
I.
1
Introduction
This
appendix
presents
unit
cost
tables
for
covering
or
treating
uncovered
finished
water
reservoirs.
This
appendix
supports
the
discussion
of
these
rule
activities
in
Chapter
6.
General
assumptions
are
provided
first,
followed
by
a
discussion
of
each
treatment
option.

I.
2
Assumptions
and
Conditions
Data
on
the
country's
138
on­
line
uncovered
finished
water
reservoirs
were
used
to
develop
national
costs
for
each
of
the
three
technology
options
for
the
Long
Term
2
Enhanced
Surface
Water
Treatment
Rule
(
LT2ESWTR):
fixed
covers,
floating
covers,
and
booster
disinfection.
For
fixed
and
floating
cover
estimates,
reservoir
surface
area
data
are
used
to
assign
costs.
Where
surface
area
information
is
unavailable
for
a
reservoir,
a
depth
is
assumed
to
determine
surface
area
for
a
given
reservoir
volume.

The
data
are
then
divided
into
14
size
categories
for
assessing
technology
costs
according
to
mean
values
per
size
category.
For
each
size
category,
an
assumed
average
hydraulic
residence
time
is
used
to
calculate
average
daily
and
design
flows.
The

Covers
Uncovered
finished
water
reservoirs
are
susceptible
to
contamination
from
bird
and
animal
waste
and
airborne
deposition.
Covering
the
reservoirs
can
provide
protection
from
water
quality
deterioration.
In
addition
to
providing
public
health
protection,
covers
prevent
algal
growth
and
reduce
the
amount
of
chlorine
lost
during
storage
by
excluding
sunlight
(
Griffith
1988).

A
number
of
factors
are
involved
in
determining
a
suitable
cover,
including
reservoir
size
and
shape,
geological
stability
of
the
area,
estimated
snow,
wind
and
seismic
loads
put
on
the
reservoir,
length
of
time
the
reservoir
would
be
taken
off­
line
for
construction,
existing
reservoir
rehabilitation,
and
construction
and
operations
and
maintenance
(
O&

costs.
The
rest
of
this
section
explains
the
estimated
capital
and

costs
associated
with
fixed

Floating
Covers
Floating
covers
are
flexible
membrane
structures,
either
air­
supported
fabric
or
polypropylene
material,
that
rest
on
the
surface
of
open
reservoirs.
For
drainage
purposes,
floating
covers
should
be
flexible
as
they
tend
to
collect
rainwater
and
washwater.
Routine
monitoring
for
damage
and
proper
maintenance
and
cleaning
of
the
cover
will
extend
its
useful
life.
For
this
Economic
Analysis
(
EA),
floating
cover
material
is
assumed
to
be
polypropylene.
Material
costs
are
estimated
at
$
2.00/
sq.
ft.,
and
O&
M
cost
estimates
are
3
percent
of
total
capital
costs
(
USEPA
1999c).
For
each
size
category,
material
costs
are
estimated
for
the
mean
surface
area.

Based
on
best
professional
judgment,
engineering
contingencies
(
construction,
standby
power,
contractor
overhead
and
profit
(
O&
P),
legal,
fiscal
and
administrative
costs)
are
estimated
to
be
35
percent
of
material
costs.

capital
and
O&

Fixed
Covers
Fixed
covers
are
permanent
structures
constructed
to
direct
drainage
away
from
the
reservoir
and
prevent
other
contamination
of
the
stored
water
(
USEPA
1999c).
These
permanent
structures
can
be
made
from
wood,
steel,
reinforced
concrete,
or
aluminum.

Due
to
high
capital
costs,
fixed
covers
are
typically
limited
to
smaller
sized
reservoirs,
up
to
20
million
gallons.
However,
fixed
covers
require
little
or
no
O&
M
expenses.

For
this
EA,
fixed
cover
material
is
assumed
to
be
common
concrete
material.
In
the
same
manner
as
the
floating
cover
cost
model,
costs
are
estimated
for
the
mean
surface
area
for
each
size
category.
Material
costs
are
$
22.00/
sq.
ft.
(
USEPA
1999c).
O&
M
costs
are
assumed
to
be
0.1
percent
of
total
capital
cost.

As
with
floating
cover
cost
estimates,
engineering
contingencies
are
included
at
35
percent
of
capital
costs.

Disinfection
As
stated
previously,
uncovered
finished
water
reservoirs
are
susceptible
to
human
and
animal
contamination.
In
order
to
maintain
a
potable
water
supply,
systems
may
add
a
disinfectant
to
the
Economic

reservoir
if
they
do
not
cover
the
reservoir.
For
this
EA,
chlorination
of
finished
water
is
estimated
to
achieve
4
log
inactivation
of
viruses,
and
to
be
the
least
costly
disinfection
alternative.

To
develop
costs
associated
with
disinfection,
the
analysis
uses
the
Water
Model
(
USEPA
1984)
and
the
Water
and
Wastewater
(
W/
W)
Costs
and
Design
Criteria
Guidelines
Model
(
CWC
1994).
These
cost
models
cover
45
different
unit
treatment
processes.
Since
these
reservoirs
contain
finished
or
already
treated
water,
low­
dose
gas
chlorination
is
assumed
to
maintain
sufficient
disinfectant
residual
in
the
distribution
system;
hereafter,
this
is
referred
to
as
"
booster
chlorination."
The
Water
Model
is
used
to
estimate
capital
and
O&
M
costs
for
systems
with
average
daily
flow
capacity
less
than
or
equal
to
1
mgd;
the
W/
W
Model
is
used
for
all
average
daily
flow
capacities
greater
than
1
mgd.

EPA
evaluated
CT
requirements
from
the
1996
SWTR
Guidance
Manual
and
determined
that
a
chlorine
dose
of
1.0
mg/
l
would
provide
adequate
virus
inactivation
in
most
cases.
Other
assumptions
for
booster
chlorination
are
given
in
Exhibit
I.

To
determine
national
costs
to
comply
with
the
uncovered
reservoir
requirement
of
the
LT2ESWTR,
the
number
of
reservoirs
selecting
each
technology
is
multiplied
by
the
capital
and
O&
M
costs
for
that
technology.
To
account
for
uncertainty
when
the
total
costs
are
modeled,
a
triangular
distribution
of
+
15
percent
around
the
mean
estimate
is
assumed
for
O&
M
costs;
also
a
triangular
distribution
of
+
30
percent
around
the
mean
estimate
for
capital
costs
is
assumed.
For
each
value
10,000
values
are
drawn
to
generate
a
distribution.
Present
value
is
calculated
for
the
mean,
5th,
and
95th
percentile
at
both
3

discount
rates,
then
annualized
at

are
presented
as
average,
or

household

incurred
for
all

and
for
those

Distributions
of
household

are
also
developed,
graphically
showing
the
variability
in
costs
for

impacted
by
the

This
appendix
is
intended
to
take
the

through
the
household
cost
calculation
process.

Calculation
of
Household
Costs
Step
1:
Calculating
the
Number
of
Households
Incurring
Costs
The
first
step
in
arriving
at
annual
household
cost
estimates
is
calculating
the
total
number
of
households
subject
to
LT2ESWTR
provisions
for
each
system
size
category.
The
number
of
households
per
plant
is
calculated
by
dividing
the
average
number
of
people
served
per
plant
by
the
average
number
of
people
per
household
(
2.59
people
per
household)
for
each
system
size
category
(
U.
S.
Census
Bureau
2001a).
SDWIS
data
provides
system
populations
for
all
community
water
systems
(
CWSs)
according
to
the
established
system
population
size
categories
(
this
analysis
is
limited
to
CWSs
because
only
those
systems
serve
residential
customers)
(
USEPA
2000f).
The
average
number
of
people
served
per
plant
(
presented
in
Chapter
4)
is
derived
from
the
SDWIS
data,
while
the
number
of
people
per
household
is
the
2000
Census
Bureau
data
estimate.
This
calculation
results
in
the
number
of
households
per
plant
for
a
given
size
category.
The
following
flowchart
illustrates
this
calculation.

1
Average
number
of
people
per

is
derived
from
the

SDWIS
database
and

The
number
of
households
incurring
costs
is
estimated
separately
for
filtered
plants,
unfiltered
plants
and
uncovered
finished
water
reservoirs
and
for
each
rule
activity
(
implementation,
monitoring,
and
treatment).

The
total
number
of
households
subject
to
each
rule
activity
is
estimated
by
multiplying
the
average
number
of
households
per
plant
by
the
number
of
plants
subject
to
the
activity.
The
number
of
plants
implementing
the
rule
is
the
same
for
all
regulatory
alternatives
but
the
number
monitoring
or
adding
treatment
varies
depending
on
the
regulatory
alternative
and
the
modeled
Cryptosporidium
occurrence
distribution.
The
percentage
of
plants
conducting
each
activity
is
shown
below
and
is
derived
from
Chapter
6:

°
Implementation
­
100
percent
of
plants
(
Implementation
is
based
on
a
system
level,
but
100
percent
of
systems
perform
implementation
activities;
therefore,
100
percent
of
plants
would
also
incur
implementation
costs.)

­

70
to
90
percent
of
plants
°
Future
Monitoring
for
Cryptosporidium
­
27
to
71
percent
of
plants
The
baseline
number
of
plants
performing
implementation
and
conducting
E.
coli
monitoring
is
the
number
of
nonpurchased
plants
(
EPA
assumes
that
purchased
plants
do
not
have
untreated
source
waters
and
that
they
buy
all
their
water
from
another
system).
EPA
expects
that
the
nonpurchased
plants
will
pass
their
costs
onto
all
customers,
including
other
systems
that
purchase
water
from
them.
Because
purchased
systems
will
experience
wholesale
cost
increases
that
reflect
implementation
and
monitoring,
households
in
purchased
systems
are
included
in
the
household
calculation
as
well.
Below
is
an
illustration
that
represents
how
monitoring
and
implementation
costs
are
applied
to
households
in
purchased
and
nonpurchased
systems.

Distribution
of
Costs
Between
Purchased
and
Nonpurchased
Systems
Treatment
costs
are
estimated
for
both
purchased
and
nonpurchased
systems
(
see
Chapter
4
for
explanation
of
why
this
is
appropriate
considering
the
system
classification
scheme).

To
properly
determine
the
impact
of
costs
on
households
belonging
to
small
purchased
systems,
the
actual
costs
passed
onto
the
purchased
system
from
the
nonpurchased
system
are
taken
into
account.
The
costs
incurred
by
the
customers
of
these
small
purchased
systems
are
included
in
the
size
category
to
which
the
purchaser
belongs
and
not
to
the
larger
size
category
of
the
seller.
To
accomplish
this,
the
number
of
households
in
each
linked
size
category
as
described
in
Chapter
4
is
determined.
Then
the
percentage
of
households
in
a
linked
size
category
deriving
from
each
of
the
unlinked
size
categories
is
determined.
This
percentage
is
multiplied
by
the
total
number
of
households
in
the
linked
size
category.
The
resulting
cost
is
then
multiplied
by
the
household
water
usage
number
for
the
unlinked
size
category
to
determine
the
household
costs
for
households
served
by
that
purchased
system.

For
example,
in
the
size
category
serving
between
501
and
1,000
people
(
S3),
there
are
120,915
people
served
by
surface
water
or
ground
water
under
the
direct
influence
of
surface
water
(
GWUDI)
systems.
Of
these,
1,690
come
from
purchased
systems
in
the
101
to
500
people
served
category
(
S2)
and
132
people
come
from
the
systems
in
the
<
100

served
size
category
(
S1).
Therefore,

and
0.1

These
percentages
would
then
be
multiplied
by
the
total
number
of

in
the
size
category
to
obtain
the
number
of

incurring
the

Therefore,
for
each

in
the

98.5
percent

be
allocated
to
the

1.4

estimated
by

Step
3:
Distribution
of
Annual
Household
Treatment
Costs
(
cost
per
household)

Once
the
annual
household
costs
for
each
technology
are
derived,
they
are
paired
with
the
number
of
households
incurring
costs
for
that
specific
treatment
technology.
For
example,
in
the
101­
500
population
served
size
category,
the
number
of
households
served
by
a
plant
installing
microfiltration
will
be
paired
with
the
annual
household
cost
for
microfiltration
as
calculated
above.
This
process
is
repeated
for
each
treatment
technology
that
is
forecast
to
be
employed
within
a
given
system
size
category.
The
end
result
of
this
process
is
a
distribution
of
treatment
costs
across
a
given
system
size
category.

Step
4:
Distribution
of
Annual
Household
Implementation
and
Annual
Household
Monitoring
Costs
(
cost
per
household)

Annual
household
implementation
and
monitoring
costs
are
estimated
in
the
same
manner
as
annual
household
treatment
costs.
Implementation
costs
as
well
as
E.
coli
monitoring
costs
are
assigned
to
all
households.
Costs
for
Cryptosporidium
monitoring,
future
E.
coli
monitoring,
future
Cryptosporidium
monitoring,
and
uncovered
finished
water
reservoirs
apply
to
just
a
percentage
of
the
total
plants
and
therefore
to
a
percentage
of
the
total
households.
The
household
unit
cost
for
each
size
category
and
the
percentage
of
plants
in
each
size
category
that
must
pay
that
cost
are
used
to
generate
the
total
national
household
cost
distribution.

Step
5:
Summation
and
Presentation
of
Results
Implementation
and
E.
coli
monitoring
household
costs
are
applied
to
all
households.
Each
technology
unit
cost
is
then
added
to
the
proportion
of
households
using
that
technology
as
the
proportion
of
overall
households
incurring
that
type
of
cost.
The
costs
for
Cryptosporidium
monitoring,
future
E.
coli
and
Cryptosporidium
monitoring,
and
uncovered
finished
water
reservoirs
are
added
to
a
portion
of
households
for
each
technology.
For
example,
for
the
ICR
occurrence
distribution,
51
percent
of
plants
are
required
to
monitor
Cryptosporidium.
Therefore,
in
the
household
costs
distribution,
the
unit
cost
for
Cryptosporidium
monitoring
is
added
to
51
percent
of
the
plants
in
each
technology.
Other
types
of
costs
are
similarly
apportioned.
This
procedure
results
in
the
non­
treatment
costs
being
spread
out
randomly
over
all
systems.
EPA
recognizes
that
this
may
not
accurately
reflect
the
true
distribution
of
monitoring
and
reservoir
costs,
but
the
errors
introduced
are
small
and
it
is
difficult
to
predict
whether
for
example
systems
with
uncovered
reservoirs
would
have
to
install
treatment
on
their
plant
as
well.

J.

Household
Costs
EPA
assumes
that
increases
in
system
costs
stemming
from
implementation
of
the
LT2ESWTR
will
be
passed
onto
customers.
Exhibit
J.
3
presents
mean
expected
increases
in
yearly
household
costs
by
system
size
and
source
water
category.
These
cost
increases
incorporate
costs
for
rule
implementation,
monitoring
for
bin
classification,
uncovered
filtered
water
reservoirs,
future
monitoring
for
bin
changes,
and
treatment
changes.
Household
costs
are
estimated
separately
for
each
of
the
three
modeled
Cryptosporidium
occurrence
distributions.

Households
served
by
systems
required
to
make
treatment
changes
under
the
LT2ESWTR
will
face
much
larger
increases
in
household
water
costs
than
other
systems.
Costs
for
only
this
subset
of
households
are
also
presented
in
Exhibit
J.
4
to
enable
separate
evaluation.
Cost
increases
to
households
served
by
systems
making
treatment
changes
are
important
for
evaluating
how
the
rule
will
affect
annual
household
expenditures
nationwide.

(
see
Chapter

Approximately
95
percent
of

are
served
by

serving
at

Households

the

The
effect
of
illness
on
the
use
of
time
is
referred
to
as
time
losses
in
this
report
to
separate
these
effects
from
the
other
social
welfare
impacts
of
illness
that
are
evaluated
separately.
In
reality,
these
losses
are
shifts
in
the
use
of
time
from
its
preferred
use
to
illness­
related
activities,
and
hence
in
economic
terms
can
be
more
accurately
described
as
one
of
the
components
of
utility
losses
associated
with
illness.

Introduction
As
discussed
in
the
main
text
of
this
report,
the
value
of
averting
cryptosporidiosis­
related
morbidity
is
estimated
based
on
information
on
(
1)
the
medical
costs
associated
with
the
illness
and
(
2)
the
value
of
time
lost
due
to
illness1.
This
appendix
provides
a
more
in­
depth
discussion
of
this
approach,
describing
both
the
overall
selection
of
the
cost
of
illness
(
COI)
method
and
the
details
of
the
approach
used
to
value
time
losses.
The
appendix
focuses
on
the
rationale
for
the
methodological
choices
made
for
this
analysis;
information
on
the
specific
numerical
values
used
to
apply
this
approach
are
described
in
Appendix
L.

Appendix
K
begins
by
discussing
the
rationale
for
relying
on
COI
methods
rather
than
other
measures
of
social
welfare
(
i.
e.,
willingness
to
pay
(
WTP)
estimates)
for
valuing
the
reductions
in
risk
from
cryptosporidiosis
morbidity.
This
discussion
provides
a
brief
introduction
to
the
concept
of
WTP,
then
describes
its
relationship
to
COI
methods.
It
next
describes
the
potential
applicability
of
the
available
WTP
literature
to
the
types
of
morbidity
risks
considered
in
this
analysis
and
the
problems
with
relying
on
this
literature.
EPA's
Science
Policy
Council
has
also
considered
these
issues
and
the
reader
can
find
more
detail
in
its
Handbook
for
Non­
Cancer
Health
Effects
Valuation.

The
appendix
then
introduces
the
two
approaches
used
to
value
time
losses
in
this
Economic
Analysis.
One
approach,
the
Traditional
Cost
of
Illness
(
COI),
is
based
on
the
human
capital
approach
typically
applied
in
COI
studies,
focusing
on
the
effect
of
illness
on
labor
productivity
(
as
measured
by
work
time
lost,
whether
paid
or
unpaid).
Another
approach,
the
Enhanced
COI,
attempts
to
provide
a
more
complete
estimate
of
the
social
welfare
impacts
of
time
losses
due
to
illness
based
on
the
existing
data
and
literature.
The
subsequent
sections
of
the
appendix
then
discuss
these
approaches
for
valuing
each
type
of
time
loss
in
more
detail.

WTP
and
COI
Approaches
In
the
context
of
benefit­
cost
analysis,
the
valuation
of
human
health
risk
reductions
is
based
on
the
principles
of
neoclassical
welfare
economics2.
These
principles
assume
that
each
individual
is
the
best
judge
of
his
or
her
own
well­
being
(
referred
to
as
"
utility"
by
economists),
and
that
individual
preferences
should
form
the
basis
of
valuing
any
changes
that
affect
societal
welfare.
Economic
Analysis
for
the
LT2ESWTR
Proposal
June

K­
2
In
theory,
the
dollar
value
of
the
benefits
associated
with
a
risk
reduction
is
most
appropriately
measured
by
determining
the
change
in
income
that
has
the
same
effect
on
utility
(
or
the
level
of
individual
well­
being)
as
the
change
in
risk.
Because
utility
is
impossible
to
measure
directly,
economists
typically
rely
instead
on
estimates
of
WTP
or
willingness
to
accept
(
WTA)
compensation.
WTP
is
the
maximum
amount
of
money
an
individual
would
voluntarily
exchange
to
obtain
an
improvement
(
such
as
a
risk
reduction)
given
his
or
her
budget
constraints.
WTA
is
the
least
amount
of
money
an
individual
would
accept
to
forego
the
improvement.
These
two
measures
are
not
necessarily
equal.
However,
in
practice,
economists
usually
rely
on
measures
of
WTP
because
of
concerns
about
the
accuracy
and
reliability
of
the
methods
available
for
estimating
WTA
compensation.

WTP
is
a
different
concept
than
cost
or
price.
"
Cost"
refers
to
the
resources
needed
to
produce
a
good
or
service;
it
does
not
measure
the
value
of
the
good
or
service
to
members
of
society.
"
Price"
is
determined
by
the
interactions
of
producers
and
consumers
in
the
marketplace.
For
some
individuals,
the
market
price
may
exceed
WTP,
in
which
case
they
will
not
purchase
the
good.
For
other
individuals,
WTP
may
exceed
the
current
price,
in
which
case
these
individuals
will
benefit
from
the
fact
that
the
market
price
is
less
than
they
are
willing
to
pay.

Estimates
of
WTP
can
be
derived,
however,
from
price
and
quantity
data
for
goods
that
are
bought
and
sold
in
the
marketplace
(
i.
e.,
"
market
goods").
For
other,
"
nonmarket,"
goods
 
such
as
health
risk
reductions,
economists
generally
group
methods
for
estimating
WTP
into
two
categories.
The
first
category,
"
stated
preference"
methods,
involves
asking
individuals
what
they
would
be
willing
to
pay
for
a
change
in
health
risk
or
another
nonmarket
good.
The
most
commonly
used
stated
preference
approach
is
the
contingent
valuation
method,
which
involves
surveying
individuals
and
asking
them
how
much
they
would
be
willing
to
pay
for
a
hypothetical
nonmarket
good
given
their
existing
household
budget.

The
second
category
of
valuation
approaches
for
nonmarket
goods
includes
"
revealed
preference"
methods,
and
involves
looking
at
behavior
for
related
goods.
One
example
of
these
methods
is
wage­
risk
studies,
which
estimate
the
change
in
wages
required
for
riskier
jobs,
using
statistical
methods
to
control
for
the
many
factors
other
than
risk
that
affect
wage
levels.
Another
example
of
revealed
preference
methods
is
averting
behavior
models,
which
consider
market
goods
that
are
purchased
at
least
in
part
to
achieve
risk
reductions
 
such
as
bottled
water
or
home
filters.
These
latter
methods
are
rarely
used
in
practice
however,
due
to
difficulties
in
sorting
out
the
value
of
risk
reductions
from
the
values
associated
with
other
characteristics
of
the
product
(
e.
g.,
improved
taste
or
convenience).

COI
studies
differ
from
these
stated
and
revealed
preference
methods
in
that
they
are
a
measure
of
cost
rather
than
WTP.
These
studies
examine
the
actual
direct
costs
(
e.
g.,
medical
expenses
such
as
doctor
visits,
medication,
and
hospital
stays)
incurred
by
individuals
affected
by
the
illness.
The
COI
method
is
relatively
easy
to
apply
because:
(
1)
it
is
well
developed,
widely
used,
and
easily
explained;
(
2)
many
of
the
types
of
costs
it
includes
are
easily
measured;
and
(
3)
existing
studies
provide
estimates
for
a
large
number
of
illnesses.
For
these
reasons,
this
method
is
often
used
in
economic
analyses
despite
its
shortcomings
as
a
proxy
for
WTP.

In
general,
the
logic
for
using
COI
methods
is
that,
if
illness
imposes
the
costs
of
medical
expenditures
and
foregone
earnings,
then
a
policy
that
reduces
illness
yields
benefits
equal,
at
a
minimum,
to
the
costs
saved
(
Tolley
et
al.
1994).
However,
COI
estimates
may
underestimate
individual
WTP
because
they
do
not
explicitly
address
the
value
of
avoiding
the
pain
and
suffering
associated
with
the
illness
(
especially
the
Traditional
COI),
nor
the
costs
that
individuals
incur
to
avoid
the
illness
(
often
3
COI
estimates
may,
in
some
limited
cases,
overstate
WTP
 
for
example,
because
the
availability
of
insurance
may
lead
people
to
agree
to
treatments
that
they
would
not
willingly
finance
themselves.

In
addition,
COI
estimates
do
not
reflect
aversion
to
risk,
i.
e.,
the
effect
of
fear
of
illness
on
WTP.
In
contrast
to
welfare
measures
based
on
ex
ante
WTP
to
avert
health
risks,
COI
measures
examine
the
actual
ex
post
costs
to
society
associated
with
treating
the
health
effects.
Finally,
in
cases
where
treatment
does
not
return
people
to
their
original
health
state,
these
methods
will
underestimate
the
benefit
of
avoiding
the
illness
entirely.

COI
studies
sometimes
include
indirect
as
well
as
direct
costs.
These
indirect
costs
usually
include
lost
earnings
due
to
missed
market
work
time,
and
occasionally
include
costs
associated
with
lost
nonmarket
work
(
e.
g.,
housekeeping),
(
both
are
included
in
the
Traditional
COI
and
Enhanced
COI
estimates),
and
reduced
productivity
while
at
work
(
which
is
included
in
the
Enhanced
COI).
Typically,
these
costs
are
estimated
using
the
human
capital
approach,
which
(
as
discussed
in
more
detail
later
in
this
appendix)
focuses
on
the
effect
of
time
use
on
the
production
of
goods
and
services
and
ignores
other
aspects
of
time
use
that
affect
individual
well­
being.

Given
these
concerns,
the
COI
method
is
an
imperfect
substitute
that
is
applied
in
cases
where
suitable
WTP
studies
are
not
available.
The
following
section
discusses
the
available
WTP
literature
and
its

to
the

Review
of
the
Literature
on
WTP
for
Morbidity
Risk
Reductions
This
analysis
uses
a
variant
of
the
COI
approach
to
value
reductions
in
cryptosporidiosis
morbidity
risks
because
of
the
lack
of
suitable
WTP
studies
of
reasonable
quality.
EPA
conducted
several
reviews
of
the
valuation
literature
and
found
relatively
few
studies
that
address
morbidity
risks4.
Many
of
these
studies
focus
on
relatively
serious
and
often
chronic
conditions
such
as
asthma,
chronic
bronchitis,
or
angina;
a
few
consider
very
minor
acute
affects
such
as
drowsiness,
headache,
or
eye
irritation.
In
general,
these
conditions
appear
significantly
dissimilar
to
the
effects
of
cryptosporidiosis
and,
hence,
do
not
provide
suitable
valuation
estimates
for
the
purposes
of
this
analysis.

Of
particular
interest
are
two
inter­
related
studies
of
nausea
(
as
well
as
other
minor
health
symptoms)
that
were
completed
by
overlapping
groups
of
researchers
in
1984­
1985
in
Chicago
and
Denver.

Based
on
a
contingent
valuation
survey,
Berger
et

(

of
nausea.
The
authors
report
results
only
for
the
17
individuals
sampled
who
had
experienced
the
symptom,
and
found
a
mean
value
of

Another
contingent
valuation
study
by
Tolley
et
al.
(
1986)
also
considered
nausea,
described
as
a
"
lingering
urge
to
vomit"
with
strong
distress,
but
no
pain.
The
mean
value
for
avoiding
one
additional
day
of
nausea
was
$
50
(
dollar
year
not
reported)
among
the
176
respondents6.
Both
estimates
appear
unsuitable
for
the
analysis
of
cryptosporidiosis
morbidity
risks
in
terms
of
both
applicability
and
quality,
based
on
EPA
guidelines
for
determining
whether
benefits
estimates
are
suitable
for
transfer
to
other
contexts7.
First,
they
describe
a
symptom
that
is
substantially
less
severe
than
the
suite
of
symptoms
typically
associated
with
cryptosporidiosis,
which
often
involves
several
days
of
diarrhea,
abdominal
cramping,
fever,
and
vomiting,
as
well
as
nausea.
Second,
Berger
in
particular
relies
on
a
small
sample
that
may
not
be
representative
of
the
U.
S.
population
(
or
of
the
subset
of
this
population
affected
by
this
rulemaking),
and
may
be
best
described
as
a
pilot
or
illustrative
study8.
Given
the
more
severe
symptoms
associated
with
cryptosporidiosis,
WTP
to
avoid
cryptosporidiosis
is
likely
to
exceed
the
WTP
values
for
nausea
found
in
these
studies.

Due
to
the
lack
of
suitable
WTP
estimates,
this
report
instead
relies
largely
on
COI
estimates
from
the
studies
cited
in
the
main
text.
These
studies
have
the
advantage
of
directly
addressing
cryptosporidiosis
or
illnesses
that
have
very
similar
health
effects
(
i.
e.,
giardiasis).
However,
they
are
likely
to
underestimate
individual
WTP
for
risk
reductions.
Research
on
the
ratio
of
WTP
to
COI
estimates
suggests
that
the
ratio
of
these
values
varies
greatly
depending
on
the
nature
of
the
health
effect,
the
characteristics
of
the
affected
individuals,
and
the
factors
included
in
constructing
each
estimate.
The
resulting
WTP
to
COI
ratios
for
the
illnesses
studied
range
from
about
a
factor
of
2
to
as
much
as
a
factor
of
79
(
in
one
case);
many
of
the
ratios
are
between
3
and
69.
In
other
words,
the
COI
estimates
are
typically
one­
third
to
one­
sixth
of
the
WTP
estimates.
Much
of
this
literature
focuses
on
individual
(
out­
of­
pocket)
costs
of
illness
rather
than
the
full
costs
(
including
costs
paid
by
insurers),
and
considers
relatively
minor
health
effects
(
where
the
costs
borne
by
insurers
may
be
minimal).
Few
of
these
studies
include
lost
earnings
or
other
indirect
costs
in
the
COI
estimates,
and
instead
focus
largely
on
medical
expenditures.

The
approach
used
to
estimate
medical
costs
in
constructing
the
COI
estimates
used
in
this
report
is
discussed
in
detail
in
Chapter
5
and
Appendix
L.
The
remainder
of
this
appendix
focuses
on
the
approaches
used
in
this
Economic
Analysis
to
value
lost
time.
As
discussed
below,
this
approach
uses
both
a
traditional
approach
(
that
is,
similar
to
other
studies)
and
an
"
enhanced"
approach,
which
is
a
significant
departure
from
the
approach
typically
used
to
value
time
losses
in
the
COI
literature
because
it
attempts
to
provide
a
more
complete
measure
of
the
effects
of
lost
time
on
social
welfare.
10
Paid
care
is
included
in
the
medical
cost
component
of
the
analysis
and,
hence,
is
not
discussed
in
the
section
on
time
losses.

11
This
approach
implicitly
assumes
that
labor
markets
are
in
equilibrium
and
that
there
is
little
or
no
unemployment
(
i.
e.,
workers
cannot
be
replaced).

Welfare
Effects
of
Time
Losses
Due
to
Illness
Much
of
the
research
on
the
value
of
time
losses
due
to
illness
focuses
on
the
effects
of
such
losses
on
the
production
of
goods
and
services
by
the
affected
individuals.
In
the
context
of
benefit­
cost
analysis,
analysts
are
interested
in
a
more
complete
measure
of
the
welfare
effects
of
these
time
losses.
As
discussed
by
A.
Myrick
Freeman
III
(
1993)
in
his
seminal
work
on
benefits
valuation:

The
economic
concept
of
value
employed
here
has
its
foundation
in
neoclassical
welfare
economics.
The
basic
premises
of
welfare
economics
are
that
the
purpose
of
economic
activity
is
to
increase
the
well­
being
of
individuals
who
make
up
society,
and
that
each
individual
is
the
best
judge
of
how
well
off
he
or
she
is
in
a
given
situation.
Each
individual's
welfare
depends
not
only
on
that
individual's
consumption
of
private
goods
and
of
goods
and
services
produced
by
the
government,
but
also
on
the
quantities
and
qualities
each
receives
of
nonmarket
goods
and
service
flows....

In
this
context,
analysts
are
concerned
with
the
effect
of
illness
on
foregone
market
production
(
paid
work),
foregone
nonmarket
production
(
e.
g.,
volunteer
or
household
activities),
and
any
additional
diminished
utility
(
or
sense
of
well­
being)
associated
with
work
and
nonwork
activities.
Analysts
are
also
concerned
with
the
impacts
on
other
individuals
such
as
dependent
children
or
unpaid
caregivers.
10
In
contrast,
most
of
the
work
on
valuing
time
losses
has
been
completed
in
the
context
of
estimating
the
market
impacts
of
illness,
focusing
on
the
ill
individual.
In
this
context,
lost
time
generally
has
been
measured
using
the
human
capital
approach,
which
views
individuals
as
mechanisms
of
production;
i.
e.,
as
capital.
Under
this
approach,
an
individual
is
valuable
to
the
extent
that
he
or
she
produces
goods
or
services,
and
the
value
of
his
or
her
marginal
product
is
equal
to
the
compensation
provided11.
The
analyst
is
generally
not
concerned
with
other
(
nonmarket)
factors
affecting
individuals'
sense
of
well­
being
(
except,
of
course,
if
they
affect
market
productivity).
To
again
cite
Freeman
(
1993):

The
human
capital
approach
is
fundamentally
at
odds
with
the
individualistic
perspective
of
welfare
economics
and
the
theory
of
value.
By
in
effect
asking
what
the
individual
is
worth
to
society,
the
human
capital
approach
ignores
the
individual's
own
well
being,
preferences,
and
willingness
to
pay.

One
approach
to
developing
a
more
complete
measure
of
the
value
of
lost
time
would
be
to
rely
on
estimates
of
individual
WTP
to
avoid
the
time
losses.
While
the
WTP
literature
includes
some
studies
that
address
time
losses
directly
or
indirectly,
these
studies
are
of
limited
relevance
to
the
types
of
time
losses
discussed
in
this
report,
as
discussed
below.

Some
WTP
studies
include
explicit
information
on
time
losses
when
eliciting
the
value
of
averting
particular
health
effects.
For
example,
Rowe
and
Chestnut
(
1986)
surveyed
90
asthmatic
individuals
in
1983
to
estimate
their
WTP
for
a
program
that
would
reduce
their
bad
asthma
days.
The
survey
elicited
12
Travel
cost
studies
are
focused
on
the
costs
(
or
negative
impacts)
associated
with
traveling
longer
distances.
They
assume
that
travel
time
has
some
positive
effects
(
or
utility),
otherwise
time
costs
would
be
valued
at
the
full
wage
rate
(
i.
e.,
as
a
complete
loss).

information
on
the
effects
of
asthma
on
work,
school,
chores,
and
leisure
activities.
However,
the
authors
ask
the
respondents
to
report
their
WTP
for
a
program
to
decrease
bad
asthma
days;
an
estimate
of
WTP
to
avoid
time
losses
is
not
reported
separately.

Researchers
interested
in
valuing
the
availability
of
recreational
activities
also
consider
time
costs
in
the
context
of
recreational
demand,
or
travel
cost,
studies.
These
studies
typically
value
time
spent
traveling
to
a
recreation
site
at
a
fixed
fraction
of
the
individual's
wage
rate,
which
represents
the
disutility
associated
with
travel12.
The
precise
fraction
of
the
wage
rate
used
to
value
travel
time
costs
has
ranged
from
zero
to
one
in
published
empirical
studies.
Unfortunately,
these
studies
are
focused
on
a
particular
use
of
leisure
time,
i.
e.,
for
travel.
The
resulting
estimates
are,
therefore,
not
necessarily
applicable
to
other
types
of
leisure
activities.

Another
potentially
relevant
approach
is
assessing
the
value
of
restricted
activity
days.
These
days
are
generally
defined
as
time
periods
when
individuals
find
that
their
activities
are
more
limited
than
normal
due
to
illness
or
other
factors.
This
concept
is
frequently
applied
in
the
context
of
assessing
health
effects
associated
with
air
pollution.
For
example,
researchers
have
linked
self­
reported
data
on
activity
restrictions
to
data
on
air
pollution
levels
to
estimate
the
effects
of
this
pollution
on
normal
activities.
Information
on
WTP
for
avoiding
these
restrictions
(
derived
from
studies
of
minor
respiratory
symptoms)
is
then
applied
to
the
estimates
of
activity­
restricted
days
to
determine
their
value13.
However,
this
value
will
vary
depending
on
the
type
and
severity
of
the
activity
limitations,
as
well
as
the
nature
of
the
health
effects
experienced.
As
noted
earlier,
sparse
information
is
available
on
WTP
to
avoid
the
types
of
health
effects
or
activity
restrictions
associated
with
cryptosporidiosis.
In
the
absence
of
this
information,
it
is
not
possible
to
apply
this
approach
to
the
health
effects
considered
in
this
report.

This
analysis
instead
relies
on
wage
and
compensation
data
to
estimate
opportunity
costs
to
the
individual
and
society,
due
to
the
lack
of
applicable
studies
that
estimate
WTP
for
time
losses
due
to
illness.
The
opportunity
cost
approach
recognizes
that,
because
resources
are
limited,
any
decision
to
use
resources
for
one
purpose
means
that
they
cannot
be
used
for
other
purposes.
Hence,
the
value
of
the
resource
can
be
determined
based
on
the
value
of
its
next
best
use.
This
approach
is
likely
to
understate
the
full
value
of
time
losses,
since
individuals
may
hold
values
that
exceed
the
opportunity
costs
represented
by
measures
of
compensation.

The
use
of
wage
and
compensation
data
to
estimate
opportunity
costs
is
consistent
with
the
basic
principles
of
welfare
economics
and
is
explored
in
detail
in
the
labor
economics
literature.
For
example,
as
summarized
in
the
Gold
et
al.
(
1996)
study
of
"
best
practices"
for
cost­
effectiveness
analysis:

The
fundamental
assumption
of
this
literature
is
that
people
will
take
their
opportunity
cost
into
account
when
allocating
their
time,
choosing
to
devote
it
to
the
activities
that
produce
the
greatest
utility.
They
will
work
an
extra
hour,
for
example,
if
the
compensation
they
receive
exceeds
the
value
they
place
on
their
time
in
other
activities.

The
application
of
the
opportunity
cost
approach
to
estimate
the
value
of
lost
market
(
paid)
work
time
is
relatively
clear,
since
compensation
can
be
used
to
estimate
these
costs.
For
other
(
unpaid)
time
spent
in
nonmarket
work
or
leisure
activities,
wage
data
are
also
used
based
on
the
assumption
that
(
at
the
margin)
the
wage
represents
the
opportunity
cost
of
engaging
in
such
activities14.
To
again
cite
Gold
et
al.
(
1996):

The
labor­
leisure
trade­
off,
which
is
at
the
heart
of
the
theory
of
labor
supply,
illustrates
the
method
used
to
value
time
which
is
not
spent
at
work:
if
there
is
perfect
competition;
if
workers
and
employers
are
perfectly
well
informed;
if
the
worker
has
declining
marginal
utility
of
leisure
time
(
i.
e.,
the
more
time
spent
away
from
work,
the
lower
the
value
of
each
incremental
increase
in
leisure
time)
and
diminishing
marginal
utility
of
income;
and
if
the
quantity
of
labor
supplied
in
the
market
is
continuously
variable,
then
the
worker
"
consumes"
leisure
time
up
to
the
point
at
which
the
value
of
an
additional
hour
of
leisure
equals
the
(
hourly)
wage
that
he
or
she
can
receive
by
working.

As
indicated
by
this
quote,
the
use
of
wage
data
to
estimate
opportunity
costs
is
based
on
a
number
of
simplifying
assumptions
regarding
the
operations
of
labor
markets
and
the
process
by
which
individuals
choose
among
different
activities.
In
addition
to
the
limitations
cited
above,
this
approach
assumes
that
an
individual
has
complete
flexibility
in
choosing
the
number
of
hours
he
or
she
spends
in
paid
work,
whereas
in
reality
employers
may
be
willing
to
provide
jobs
only
for
set
increments
of
time
(
e.
g.,
40
hours
per
week).
In
its
simplest
form,
it
also
does
not
take
into
account
a
number
of
complexities
related
to
how
individuals
are
actually
compensated,
such
as
the
difference
between
hourly
and
salaried
employees
and
variation
in
how
benefits
are
determined.

In
addition,
relying
on
wage
data
for
valuing
lost
time
presents
difficulties
in
the
case
of
individuals
for
whom
these
data
are
not
available,
such
as
children,
the
unemployed
who
are
seeking
employment,
and
those
out
of
the
labor
market.
It
also
can
be
difficult
to
define
a
value
when
there
are
trade­
offs
between
two
uncompensated
activities.
Perhaps
most
important,
the
use
of
wage
rates
may
understate
the
total
utility
associated
with
the
activity
even
in
the
case
of
paid
work,
because
individuals
may
derive
intrinsic
pleasure
from
the
activity
above
and
beyond
the
income
they
receive.

The
use
of
compensation
data
to
value
time
losses
and
its
limitations
are
explored
in
detail
in
the
following

of
this
appendix.
The

the
compensation
measures

As
discussed
in
detail
in
the
main
text
of
this
report,
cryptosporidiosis
often
involves
several
days
of
diarrhea,
abdominal
cramping,
fever,
and
vomiting,
as
well
as
nausea.
Many
characteristics
of
this
illness
are
of
particular
importance
when
considering
the
approach
to
valuing
time
losses
in
each
of
these
four
categories.
Specifically,
the
valuation
approach
needs
to
accomplish
the
following:

°
Consider
time
losses
associated
with
morbidity,
not
mortality
because
other,
well­
established
valuation
methods
are
applied
to
mortality
risks.

°
Apply
to
acute,
not
chronic,
illnesses,
that
generally
result
in
a
temporary
rather
than
permanent
change
in
activities.

°
Address
illnesses
that
may
lead
individuals
to
both
spend
fewer
hours
engaged
in
normal
activities,
and
have
a
lower
level
of
productivity
or
utility
when
they
continue
normal
activities.

°
Consider
effects
that
may
occur
throughout
the
day,
potentially
affecting
all
types
of
time
usage.

°
Apply
to
individuals
of
all
ages
that
may
be
affected
by
this
illness,
including
the
very
old
and
the
very
young.

°
Reflect
the
need
of
some
ill
individuals
for
the
attention
of
a
caretaker
(
i.
e.,
a
friend
or
family
member,
not
a
paid
health
care
provider)
for
a
portion
of
the
time
while
they
are
ill.
15
16
There
are
a
number
of
simplifying
assumptions
inherent
in
the
application
of
this
approach
that
may
lead
it
to
further
under­
or
over­
state
the
value
of
time
in
its
preferred
use,
related
to
factors
such
as
the
functioning
of
the
labor
market,
the
treatment
of
individuals
who
are
not
labor
force
participants,
and
the
use
of
average
or
median,
rather
than
marginal,
earnings
data.
It
is
unclear
whether,
in
total,
these
practical
limitations
serve
to
increase
or
decrease
the
bias
that
results
from
the
sources
discussed
in
this
paragraph.

Because

this

In
this
analysis,
lost
market
work
time
is
valued
at
the
pre­
tax
wage
rate
plus
benefits.
Using
the
Enhanced
COI
estimate,
lost
nonmarket
work
and
leisure
time
are
valued
at
the
post­
tax
wage
rate.
The
Traditional
COI
estimate
values
nonmarket
work
time
at
half
the
net
post­
tax
wage
rate,
and
does
not
include
a
value
for
leisure
time.
Lost
sleep
time
is
conservatively
valued
at
"
zero."
Losses
are
assessed
for
unpaid
caretakers
whose
normal
activities
are
affected
by
illness
as
well
as
for
the
ill
individual.

In
the
Enhanced
COI
estimate,
these
values
are
applied
to
both
complete
losses
of
time
(
time
spent
in
illness­
related
activities
rather
than
normal
activities),
as
well
as
to
partial
losses
(
time
spent
in
normal
activities
that
are
less
productive
or
pleasurable
than
in
the
absence
of
illness).
In
the
latter
case,
however,
the
dollar
value
of
the
loss
is
prorated
to
reflect
the
fact
that
the
individual
does
not
completely
lose
the
productivity
or
utility
associated
with
the
activity.
In
the
Traditional
COI
estimate,
these
values
are
applied
only
to
complete
losses
of
time
(
time
spent
in
illness­
related
activities
rather
than
normal
activities),
because
less
productive
time
is
not
included.

Both
of
these
approaches
are
likely
to
understate
the
utility
of
time
spent
in
its
preferred
use
(
i.
e.,
of
normal
activities
in
the
absence
of
illness)
for
variety
of
reasons16.
Individuals
may
place
a
value
on
market
work
that
exceeds
total
compensation
because
of
the
effect
of
working
on
their
sense
of
wellbeing
For
nonmarket
work
and
leisure,
the
value
of
the
activity
to
the
individual
may
exceed
the
opportunity
cost
for
similar
reasons.
In
addition,
nonmarket
work
and
other
activities
can
provide
benefits
to
other
members
of
society
that
are
not
reflected
in
the
individual
wage
rate.
Finally,
neither
approach
includes
the
value
of
sleep.
17
Embedded
in
this
approach
are
a
number
of
assumptions
(
discussed
earlier)
regarding
the
operations
of
the
labor
market
and
the
factors
that
influence
individual
choice.
In
addition,
the
actual
effect
of
missed
work
time
will
vary
depending
on
how
individuals
are
compensated;
e.
g.,
on
whether
they
are
salaried
or
hourly
employees
and
on
whether
they
receive
sick
leave
or
disability
payments.
For
example,
if
the
individual
has
access
to
paid
sick
leave,
a
marginal
loss
of
work
time
(
within
certain
limits)
will
not
result
in
an
immediate
loss
of
income.
However,
a
loss
will
accrue
to
the
employer,
who
must
pay
wages
without
the
benefit
of
the
worker's
productivity.
The
individual
also
has
the
ability
to
save
this
sick
leave
for
another
time.

18
A
number
of
COI
studies
use
lost
earnings
to
estimate
indirect
costs.
For
example,
the
total
compensation
approach
is
used
in
Buzby
et
al.
(
1996),
Rice
et
al.
(
1992),
and
Waitzman
et
al.
(
1996).

However,
it
is
unclear
whether
the
use
of
these
estimates
over­
or
under­
state
the
disutility,
or
loss,
associated
with
illness;
i.
e.,
the
loss
associated
with
spending
time
in
illness­
related,
rather
than
normal,
activities.
In
some
cases,
it
seems
reasonable
to
assume
that
the
illness­
related
activity
represents
a
complete
loss
of
utility
(
e.
g.,
time
spent
coping
with
a
bout
of
diarrhea
rather
than
working).
For
these
losses,
the
approaches
used
in
this
report
will
understate
the
value
of
the
loss,
as
discussed
in
the
prior
paragraph.
In
other
cases,
the
illness­
related
activity
may
have
some
utility
(
e.
g.,
time
spent
watching
TV
or
reading
instead
of
working)
that
is
less
than
the
utility
of
the
preferred
activity,
but
greater
than
"
zero."
Even
in
this
case,
there
would
likely
be
some
offsetting
utility
losses
from
the
discomfort
and
stress
of
being
sick.
In
these
cases,
the
actual
amount
of
the
loss
could
conceivably
be
less
than
the
estimates
used
in
this
analysis.
The
basis
for
these
approaches
is
described
in
more
detail
below.

K.
5.1
Lost
Market
Work
Time
In
a
social
welfare
context,
the
value
of
marginal
changes
in
market
work
time
has
two
components:
(
1)
the
value
of
the
time
loss
to
that
individual,
and
(
2)
any
additional
value
to
the
rest
of
society.
In
this
analysis,
lost
market
work
is
valued
at
the
median
gross
(
pre­
tax)
wage
rate
plus
benefits,
also
referred
to
as
total
compensation
or
employer's
costs17.
This
approach
is
most
representative
of
the
full
social
impact
of
lost
work
time
because
it
incorporates
both
the
loss
to
the
individual
in
terms
of
lost
income
and
the
loss
to
society
in
terms
of
reduced
tax
revenue
or
decreased
production
of
goods
and
services.

This
approach
recognizes
that,
when
an
individual
misses
work
or
is
less
productive
due
to
illness,
he
or
she
loses
the
associated
utility.
This
loss
is,
in
part,
measured
by
income,
which
the
individual
can
trade
for
goods
and
services.
However,
income
is
an
incomplete
measure
of
value,
because
the
individual
may
derive
utility
from
working
that
exceeds
post­
tax
wages
or
take
home
pay.
Hence
the
post­
tax
wage
rates
provide
a
lower
bound
estimate
of
the
value
of
paid
work
time
from
the
individual
perspective.

This
approach
also
recognizes
that
the
employer
(
and
society)
loses
the
value
of
the
individual's
productivity,
and
that
this
value
exceeds
the
value
of
the
post­
tax
wages
received
by
the
employee.
From
the
employer's
perspective,
the
value
of
the
individual's
productivity
is
equal
at
minimum
to
his
or
her
total
compensation
(
pre­
tax
wages
plus
benefits).
This
perspective
is
similar
to
that
of
the
human
capital
approach,
which
assumes
that
an
employer
would
not
pay
more
to
an
employee,
in
salary
plus
benefits,
than
that
employee
is
worth
to
the
company
(
i.
e.,
the
value
of
the
employee's
marginal
product)
and
hence
to
society18.
Some
of
this
value
is
reflected
in
the
employee's
take
home
pay,
the
remainder
19
For
a
recent
discussion
that
indicates
that
illness­
related
losses
of
work
time
can
substantially
exceed
the
wage
rate,
see:
Pauley
et
al.
(
2002).

20
Hartunian
et
al.
(
1981)
and
others
argue
that
average
wages
are
a
reasonable
approximation
of
the
value
of
lost
production
in
most
industrialized
countries.

21
A
number
of
groups
have
been
working
on
approaches
for
measuring
and
categorizing
different
types
of
time
usage,
as
summarized
in

Research
Council
(
2000).

terms
of
taxes
paid
and
reflects
the
value
of
product
created
above
and
beyond
what
is
reflected
in
pre­
tax
wages.
19
Ideally,
the
estimates
used
in
this
analysis
would
reflect
the
value
of
marginal
changes
in
work
time,
since
the
impacts
of
cryptosporidiosis­
related
morbidity
are
likely
to
be
acute
and
temporary.
In
other
words,
affected
individuals
may
work
fewer
hours
or
be
less
productive
while
working
for
a
limited
period
of
time,
but
are
not
likely
to
change
employment
or
become
unemployed
as
a
result
of
the
illness.
Empirically,
analysts
generally
use
estimates
of
average
or
median
compensation
as
a
proxy
for
marginal
rates
due
to
difficulties
inherent
in
determining
the
marginal
rates
relevant
to

Lost
Nonmarket
Work,
Leisure
Time,
and
Sleep
Time
In
this
analysis,
two
alternative
measures
are
used
to
value
nonmarket
work
time
and
leisure
time.
In
the
Enhanced
COI
estimate,
net
(
post­
tax)
wages
are
used
to
estimate
the
value
of
both
lost
nonmarket
work
and
leisure
time.
In
the
Traditional
COI
estimate,
the
value
of
lost
nonmarket
work
time
is
half
the
post­
tax
wage,
and
no
value
is
assigned
to
leisure
time.

While
the
distinctions
between
market
work
and
sleep
are
relatively
easy
to
distinguish,
the
line
between
nonmarket
work
and
leisure
is
often
difficult
to
draw21.
In
general
parlance,
nonmarket
work
refers
to
activities
that
are
undertaken
primarily
because
they
are
productive,
whereas
leisure
refers
to
activities
that
are
undertaken
primarily
for
the
pleasure
of
the
individual.
However,
this
distinction
is
hard
to
apply
in
practice.
Some
nonmarket
tasks
seem
clearly
productive,
such
as
doing
the
laundry
or
vacuuming,
but
individuals
may
also
derive
pleasure
from
these
tasks.
Other
activities,
such
as
childcare
or
gardening,
encompass
aspects
of
both
productive
work
and
of
leisure.

Nonmarket
Work
One
of
the
two
alternative
measures
used
in
this
analysis
to
value
nonmarket
work
time
is
the
net
(
post­
tax)
wages,
which
are
used
to
estimate
the
value
of
lost
nonmarket
work
in
the
Enhanced
COI
estimate.
If
illness
affects
an
individual's
ability
to
engage
in
nonmarket
work,
he
or
she
loses
the
value
of
his
or
her
own
productivity.
Presumably,
that
individual
chooses
to
engage
in
nonmarket
rather
than
market
work
because,
at
the
margin,
the
utility
(
productivity
plus
any
additional
enjoyment)
from
performing
nonmarket
work
was
greater
than
the
utility
(
as
represented
by
income)
that
he
or
she
would

Benefits
are
conservatively
left
out
of
this
calculation,
under
that
assumption
that
marginal
changes
in
the
number
of
hours
worked
would
not
affect
the
total
amount
of
benefits
received.

24
For
example,
a
series
of
studies
funded
by
the
Australian
Bureau
of
Statistics
focus
on
adding
the
value
of
nonmarket
work
to
national
accounts
and
use
the
replacement
cost
method
for
this
purpose.

for

Time
use
researchers
have
been
attempting
to
develop
classification
schemes
that
can
be
used
internationally
for
these
types
of
studies.
Many
refer
to
four
general
categories:
contracted
time
(
paid
work
plus
education
and
training),
committed
time
(
unpaid
work,
including
housework,
shopping,
and
volunteer
work),
necessary
time
(
personal
care,
including
sleep),
and
free
time
(
religious,
cultural
and
civic
participation,
social
time,
sports,
hobbies,
and
mass
media).
(
See,
for
example,
Ministry
of
Women's
Affairs,
Statistics
New
Zealand
(
1999).)
These
classification
schemes
differ
somewhat
from
the
categories
used
in
the
report,
and
require
more
detailed
data
on
the
types
of
time
uses
affected
than
are
available
for
this
analysis.

have
gained
from
market
work22.
Therefore,
that
individual
must
value
a
marginal
hour
of
his
or
her
nonmarket
work
time
at
a
rate
at
least
equal
to
the
marginal
net
wage
per
hour
he
or
she
could
have
earned
in
the
job
market23.
It
is
not
unreasonable
to
assume
that
on
average
(
across
all
these
individuals),
the
opportunity
costs
for
these
individuals
would
be
similar
to
the
opportunity
costs
for
employed
individuals.
To
a
large
extent,
these
individuals
may
choose
to
be
out
of
the
labor
market
because
they
value
their
time
at
a
rate
that
exceeds
the
compensation
they
would
receive
by
working.
More
research
would
be
needed
to
confirm
the
extent
to
which
this
assumption
is
supported
by
detailed
studies
of
the
factors
that
affect
decision­
making
by
these
groups.
As
before,
this
approach
involves
a
number
of
simplifying
assumptions
regarding
the
functioning
of
labor
markets
and
the
choices
faced
by
individuals,
but
provides
one
reasonable
proxy
for
how
this
time
is
valued.
This
is
the
basis
used
in
the
Enhanced
COI
estimate.

The
Traditional
COI
estimate
has
a
different
basis.
The
approach
advocated
most
frequently
in
the
literature
to
distinguish
between
market
and
nonmarket
work,
particularly
in
the
context
of
adjusting
national
accounts
to
include
unpaid
work,
relies
on
estimates
of
replacement
costs
rather
than
estimates
of
opportunity
costs
and
is
known
as
the
"
third
person"
or
"
market
replacement"
criterion.
This
approach
is
used
largely
because
of
the
emphasis
of
these
studies
on
measuring
productivity
rather
than
utility24.
Under
the
human
capital
approach,
time
spent
engaged
in
nonmarket
labor
activities
is
considered
productive,
due
to
the
fact
that
activities
such
as
childcare,
cooking,
and
general
home
maintenance
 
if
not
performed
by
a
member
of
the
household
 
could
be
performed
by
a
professional
in
return
for
compensation
(
i.
e.,
as
market
labor).
As
defined
by
Reid
(
1934),
"
If
an
activity
is
of
such
a
character
that
it
might
be
delegated
to
a
paid
worker,
then
that
activity
shall
be
deemed
productive."
25
Tasks
that
can
only
be
performed
by
the
individual
himself
(
or
herself)
are
included
in
the
leisure
category.
Therefore,
gardening
and
childcare
would
be
viewed
as
nonmarket
work,
whereas
watching
television
would
be
considered
a
leisure
activity.
26
27
A
pioneering
example
of
this
approach
is
presented
in
Rice
(
1966).
A
more
recent
example,
which
uses
data
on
the
value
of
housekeeping
services

Bureau
of
Labor
statistics,
is
Ray

example
of
this
approach
is
Rice
1966;
a
more
recent
example

et

29
One
early
demonstration
of
this
market
value
approach
is
Cooper
et
al.
(
1976).
A
more
recent
approach
is
provided
in
Hoffman

which
uses
values
based
on
research
reported
in

Trewin
(
2000,
p.
24)
notes
that
the
replacement
cost
approach
"...
is
based
on
the
key
assumption
that
household
members
and
market
replacements
are
equally
productive
in
their
work
activities....
In
practice
it
is
difficult
to
identify
exact
matches
between
household
work
activities
and
occupations...."

In
some
studies,
housekeeper
wage
rates
are
used
to
value
the
productivity
of
nonmarket
labor27.
This
is
the
measure
used
to
value
lost
unpaid
work
time
for
the
Traditional
COI.
The
value
used
is
half
of
the
after­
tax
wage.
The
use
of
50
percent
of
the
wage
rate
is
consistent
with
a
practice
common
in
the
human
capital
literature
of
valuing
nonmarket
work
time
at
the
market
rate
for
domestic
workers28.
Because
this
approach
may
undervalue
the
true
productivity
of
this
labor
due
to
the
wide
range
of
activities
undertaken
in
addition
to
housekeeping
(
e.
g.,
cooking,
childcare,
and
home
repairs),
other
studies
use
market
value
composite
rates.
This
alternative
approach
would
involve
developing
a
composite
of
the
wage
rates
paid
to
individuals
employed
in
the
labor
market
to
perform
the
various
activities
typically
associated
with
nonmarket
labor
(
e.
g.,
cooks,
daycare
providers,
maids,
nannies,
and
handymen).
29,30
In
some
applications,
this
approach
has
been
expanded
to
also
include
volunteer
work31.

Leisure
For
the
Enhanced
COI
estimate,
the
approach
used
to
value
lost
leisure
time
is
the
same
as
that
applied
to
nonmarket
work.
This
approach
reflects
two
considerations:
(
1)
the
difficulties
inherent
in
developing
a
clear­
cut
distinction
between
hours
spent
in
nonmarket
work
and
leisure
as
noted
above,
and
(
2)
the
assumption
that,
at
the
margin,
an
individual
will
choose
to
engage
in
nonmarket
work
or
leisure
activities
only
if
the
value
of
these
activities
exceeds
the
wage
rate
that
the
individual
would
otherwise
earn.
The
individual
presumably
chooses
to
engage
in
activities
other
than
market
work
because,
at
the
margin,
the
utility
gained
from
these
other
activities
is
greater
than
the
utility
gained
from
market
work.
This
approach
is
a
simplification
of
how
individuals
are
likely
to
view
leisure
time.
Leisure
activities
are
undertaken
for
a
number
of
different
purposes
 
e.
g.,
to
relax,
for
exercise,
or
to
maintain
emotional
connections
with
loved
ones.
Some
leisure
activities
involve
extensive
planning
and
travel
time,
like
major
vacations,
while
others,
like
watching
television,
require
almost
no
planning,
travel,
or
even
thought.
Hence,
in
reality
the
utility
of
leisure
is
likely
to
vary
depending
on
the
activity
affected.
Even
with
these
uncertainties,
the
opportunity
cost
approach
provides
a
more
complete
measure
of
the
value
of
time
losses
from
the
perspective
of
the
individual
as
well
as
society.
This
approach
is
supported
by
the
travel
cost
studies
noted
earlier,
which
suggest
that
even
relatively
mundane
forms
of
leisure
(
such
as
travel
time)
may
have
utility
that
approaches
the
wage
rate.
The
fact
that
workers
often
demand
a
higher
hourly
wage
for
"
overtime"
work
further
supports
the
notion
that
the
marginal
value
of
nonwork
time
exceeds
the
usual
wage
rate.

Leisure
time
is
generally
not
valued
in
COI
studies
due
to
the
emphasis
of
these
studies
on
measuring
productivity
rather
than

While
leisure
time
may
have
some
impact
on
an
individual's
productivity,
this
impact
is
believed
to
be
largely
captured
in
the
valuation
of

and

From
the

capital
perspective,
including
a

value
for

runs
the
risk
of

The
loss
of

is
not

in

Lost

Sleep

presents
special
problems
in
this
analysis,
in
part
because
data
on
the
effect
of
cryptosporidiosis­
related
morbidity
on
the
amount
or
quality
of
sleep
time
are
not
available.
In
addition,
sleep
is
rarely
valued
in
the
literature
due
to
problems
related
to
determining
its
dollar
value.
Sleep
time
is
not
addressed
in
most
COI
studies
because
(
like
leisure)
its
effect
on
productivity
is
believed
to
be
largely
captured
in
the
value
of
market
and
nonmarket
work
time.

However,
from
an
opportunity
cost
perspective,
it
is
possible
to
argue
that
lost
sleep
should
be
valued
at
the
wage
rate.
For
example,
assuming
that
some
minimal
level
of
sleep
is
necessary,
sleep
time
missed
at
night
may
be
made
up
through
daytime
naps.
These
naps
in
turn
may
displace
some
of
the
time
the
individual
would
otherwise
spend
engaged
in
leisure,
nonmarket
work,
or
market
work
activities.

This
analysis
conservatively
assumes
that
lost
sleep
time
has
zero
value.
Given
that
individuals
derive
utility
from
sleep
and,
thus,
are
likely
to
value
it
at
a
rate
greater
than
zero,
this
approach
will
understate
the
value
of
related
time
losses.

Special
Considerations
Several
sub­
groups
of
the
population
present
specific
valuation
challenges,
because
they
often
do
not
engage
in
paid
work
and
hence
wage
rate
data
may
not
be
an
appropriate
measure
of
the
value
of
their
time
losses
due
to
illness.
These
groups
include
the
following.

°
Children:
Children
do
not
generally
engage
in
paid
work,
and
wage
rate
data
are
not
generally
collected
for
those
who
do.
The
definition
of
"
child"
can
vary,
but
the
age
cut­
off
is
usually
at
16
or
18
years
of
age.
The
Bureau
of
Labor
Statistics
does
not
collect
employment
data
on
individuals
under
the
age
of
16.

°
Elderly
Individuals:
As
individuals
age,
they
generally
leave
the
work
force.
However,
retired
persons
may
value
their
time
differently
than
younger
workers
who
are
out
of
the
labor
force
due
to
the
availability
of
pensions
and
Social
Security.
These
individuals
may
lose
benefits
if
they
increase
their
job­
related
income.

°
Unemployed
Individuals:
Individuals
not
currently
engaged
in
market
work,
but
actively
seeking
employment,
would
prefer
to
earn
a
wage,
but
are
not
currently
doing
so.

°
Individuals
Not
in
the
Labor
Force:
Individuals
not
currently
engaged
in
market
work,
and
not
seeking
employment,
presumably
value
their
time
at
a
rate
higher
than
the
earnings
they
could
gain
from
paid
employment.
However,
at
times
they
may
be
engaged
in
nonmarket
32
Although
an
argument
can
be
made
for
including
the
discounted
present
value
of
any
decrease
in
future
earnings,
the
types
of
acute
illnesses
considered
in
this
analysis
are
not
likely
to
have
a
measurable
impact
on
future
earnings.

Under
the

approach,
the
primary
issue
concerning
the
valuation
of
children's
time
losses
is
that
of
double
counting.
Analysts
assume
that
time
spent
in
school
or
other
productive
activities
will
be
reflected
in
future
earnings,
and
generally
assign
a
value
of
"
zero"
to
childhood
time
losses.
32
However,
from
a
social
welfare
perspective,
children
can
be
profoundly
affected
by
illness.
These
effects
may
be
direct
 
i.
e.,
children
may
be
unable
to
engage
in
normal
activities
because
they
are
ill;
or
they
may
be
indirect
 
i.
e.,
children
may
receive
a
lesser
quantity
or
quality
of
care
due
to
the
illness
of
their
caretakers.
The
dollar
values
of
these
impacts
are
highly
uncertain.

For
the
other
groups
listed
above,
the
challenge
is
largely
the
absence
of
compensation
data
as

proxy
for

Whether

approaches
taken
in

analysis
under­
state
or
over­

value
of

individuals
is
uncertain.

Cryptosporidiosis
Cost­
Related
Data
Some
of
the
most
directly
relevant
data
for
this
COI
estimate
derives
from
the
outbreak
of
cryptosporidiosis
in
Milwaukee
in
1993.
The
study
by
Corso
et
al.
(
2003)
of
this
outbreak
reports
cost
of
illness
data
using
three
categories
of
severity
of
illnesses:
mild,
moderate,
and
severe.
Definitions
of
the
categories
are
as
follows.

°
mild:
the
person
did
not
seek
medical
care
for
the
illness,
but
may
have
taken
over­
thecounter
medication
°
moderate:
the
person
had
one
or
more
outpatient
visits
to
a
physician
or
emergency
room,
but
the
person
was
not
hospitalized
°
severe:
the
person
was
hospitalized
one
or
more
times.

The
percentage
of
patients
with
each
severity
of
illness
is
reported
in
Corso
et
al.
(
2003)
(
and
derived
from
MacKenzie
et
al.,
1995)
as
87.99
percent
with
mild
cases,
10.92
percent
with
moderate
cases,
and
1.09
percent
with
severe
cases.
For
the
purposes
of
this
Economic
Analysis,
these
figures
were
rounded
to
88,
11,
and
1
percent.

In

the
total

is
reported
as
$
79
(
in

derived
from
the
above
data.
This
Economic
Analysis
uses
different
rounding
conventions,
notably,
the
rounding
of
the
percent
of
the
population
with
each
severity
of
illness.
For
comparison,
these
changes
generate
an
estimate
of
about
$
73
(
in
1993$)(
not
shown).
Further,
this
Economic

inflates
the

Calculations
for
Duration
of
Illness
for
Moderate
and
Severe
Cases
Corso
et
al.
(
2003)
does
not
provide
duration
of
illness
estimates
for
moderate
and
severe
cases,
but
does
report
that
medical
care
was
sought
in
approximately
12
percent
of
cases:
11
percent
being
"
moderate"
cases,
and
1
percent
being
"
severe"
cases..

Using
data
from
MacKenzie
et
al.
(
1994),
a
data
set
was
constructed
to
provide
a
hypothetical
population
that
could
be
evaluated
to
estimate
the
duration
of
illness
for
moderate
and
severe
cases.
This
is
because
the
MacKenzie
et
al.
(
1994)
distribution
represents
patients
with
laboratory­
confirmed
cases
of
cryptosporidiosis,
who
fit
the
requirement
that
they
sought
medical
care.
While
the
duration
of
illness
might
differ
between
those
whose
doctors
ordered
laboratory
tests
from
those
that
didn't,
no
evidence
is
available
to
suggest
a
difference
or
to
provide
a
factor
by
which
to
adjust
these
data.
In
the
absence
of
any
better
data,
the
analysis
assumes
that
this
distribution
of
illness
duration
can
be
used
to
reasonably
represent
the
collection
of
moderate
and
severe
cases.
Further,
an
assumption
is
made
that
the
severe
cases
are
best
represented
by
the
upper
tail
of
the
distribution,
and
moderate
cases
are
best
represented
by
the
lower
tail
of
the
distribution.
While
it
is
likely
the
case
that
some
severe
cases
were
of
shorter
duration
that
at
least
some
of
the
moderate
cases,
no
data
are
available
to
estimate
the
potential
overlap.
The
mean
for
moderate
cases
was
therefore
determined
by
calculating
the
average
of
the
lowest
11/
12
of
Economic
Analysis
for
the
LT2ESWTR

the
distribution.
The
mean
for
severe
cases
was
determined
by
calculating
the
average
of
the
highest
1/
12
of
the
distribution.

The
data
set
constructed
is
intended
to
approximate
the
distribution
described
by
MacKenzie
et
al.
(
1994);
one
with
a
reported
duration
of
illness
with
a
"
range
of
1
to
55
days,
mean
of
12,
and
median
of
9."
These
summary
statistics
suggest
a
nearly
lognormal
distribution,
and
we
therefore
assumed
a
lognormal
distribution
with
parameters
mu
and
sigma,

X
=
duration
of
illness
~
lognormal
(
m
,
 
s
)

Or
equivalently,

log
(
X)
~
normal
(
m
,
s
2)

To
generate
a
population
of
data
with
a
lognormal
distribution,
the
analysis
used
a
Monte
Carlo
program
that
required
a
mean
and
standard
deviation
to
define
the
lognormal
distribution.
To
derive
the
standard
deviation
from
the
mean
and
median,
we
used
the
following
relationships
that
hold
for
all
lognormal
distributions.

1.
mean
(
X)
=
exp(
m
 
+
 
s

)

2.
var
(
X)
=
exp(
2
m
+
s
2)
(
exp(
s

­
1)

and
3.
median
(
X)
=
exp(
median
(
log
(
X)))
=
exp(
m
)

Then,

9
=
median
(
X)
=
exp(
m
)
=>
m
=
ln
(
9)

12
=
mean
(
X)
=
exp(
m
+
s
2/
2)
=>
s
2
=
2(
ln(
12)
­
ln(
9))

Now,
using
formula
3
above
and
these
values
for
m
and
s
2
we
can
compute
the
variance
of
X
as
Var
(
X)
=
112,
which
implies
a
standard
deviation
of
10.58.

A
Monte
Carlo
program
was
used
to
generate
a
data
set
based
on
this
mean
and
standard
deviation.
In
this
program,
the
assumed
distribution
was
thus
set
at
a
mean
of
12
and
a
standard
deviation
of
10.58,
with
a
range
of
1
to
55,
and
multiplied
by
"
1
"
for
50,000
iterations.
The
derived
overall
mean
and
median
of
this
50,000

data
set
(
which

involves

Normal
Time
Allocation
The
U.
S.
Census
Bureau
compiles
data
on
weekly
hours
worked,
and
loss
of
work
hours
is
a
key
loss
category
used
in
this
analysis.
For
the
year
2000,
that
figure
was
39.7
hours
per
week
for
the
civilian
noninstitutional
population
16
years
old
or
older
who
are
working
full
or
part­
time.
10
This
figure
excludes
those
employed
but
not
working
because
of
vacations,
illness,
strikes,
etc.;
noncivilians;
institutionalized
persons;
and
those
in
the
labor
pool
but
unemployed.
This
group
of
workers
is
about
61.8
percent
of
the
population
in
this
age
range.
11
For
an
average
day
for
the
whole
population,
the
average
lost
work
hours
per
day
of
illness
is,
therefore,
about
3.5
hours.
12
Another
important
component
of
people's
lost
time
that
is
valued
in
the
calculation
of
benefits
is
the
time
spent
performing
nonpaid
work.
For
these
estimates,
studies
of
how
people
allocate
their
time
is
helpful.
In
recent
years,
a
number
of
research
teams
have
explored
the
allocation
of
time
across
different
activities.
For
example,
a
recent
National
Research
Council
(
2000)
study
lists
more
than
50
major
timeuse
surveys
that
have
been
completed
internationally.
However,
the
majority
of
the
studies
completed
in
recent
years
address
countries
other
than
the
United
States,
including
Australia,
the
European
Community,
Japan,
New
Zealand,
and
Canada.
The
most
recent
U.
S.
studies
were
completed
by
the
University
of
Michigan
in
1981­
1982
and
by
the
University
of
Maryland
in
1985;
the
United
States
Bureau
of
Labor
Statistics
is
in
the
process
of
developing
a
new
time­
use
study
and
expects
the
results
to
be
available
in
2004
(
United
States
Bureau
of
Labor
Statistics,
undated).

These
studies
generally
address
the
allocation
of
time
across
a
large
number
of
different
activities.
For
example,
the
proposed
U.
S.
survey
may
include
nine
groups
(
personal
care,
employment
activities,
education
activities,
domestic
activities,
care
for
dependent
household
members,
purchasing
activities,
voluntary
work
and
care,
social
and
community
interaction,
and
recreation
and
leisure)
that
are
subdivided
into
99
subgroups,
each
of
which
is
further
subdivided
into
a
number
of
discrete
categories
(
National
Research
Council
2000).
13
For
the
purpose
of
analyzing
time
losses
associated
with
nonfatal
cases
of
cryptosporidiosis,
the
dollar
value
applied
(
as
discussed
below)
varies
across
three
larger
categories:
paid
work,
unpaid
work,
and
leisure
activities,
so
more
aggregate
data
can
be
used.

Economic
Analysis
for
the
LT2ESWTR
Proposal
June

L­
9
In
lieu
of
a
recent
United
States­
based
study,
assumptions
were
made
about
time
usage,
which
were
then
compared
to
existing
data
for
reasonableness.
Specifically,
this
economic
analysis
computes
unpaid
work
time
using
40
hours
per
week
and
applying
it
to
the
38.2
percent
of
the
population
not
otherwise
employed.
While
applied
to
the
population
of
unpaid
individuals,
this
estimate
is
not
an
assumption
that
this
entire
population
is
performing
full
time
(
although
unpaid)
work,
because
this
group
includes
infants,
retired
persons,
and
others.
Nor
is
it
an
assumption
that
paid
workers
do
not
also
perform
unpaid
work.
For
an
average
day
for
the
whole
population,
the
average
lost
unpaid
work
hours
per
day
of
illness
is
about
2.18
hours.
14
This
analysis
also
assumes
that,
for
the
population
as
a
whole,
leisure
time
is
the
time
left
after
sleep
time
(
which
is
assumed
to
be
8
hours)
and
the
time
spent
in
paid
and
unpaid
work.
That
estimate
for
leisure
time
is
then
about
10.3
hours
per
day.
15
These
estimates
compare
reasonably
with
other
studies.
For
example,
a
recent
Canadian
study
addresses
a
different
population
but
has
similar
results.
Exhibit
L.
7
summarizes
the
results
of
the
Canadian
study,
which
provides
national
estimates
for
individuals
ages
15
and
older
in
1998.
The
hours
per
day
estimates
are
based
on
a
7­
day
week
for
all
time
categories.
It
seems
reasonable
to
expect
that
Canadian
time­
use
patterns
will
be
similar
to
U.
S.
patterns
due
to
the
proximity
of
the
two
countries
and
the
extent
of
interaction
between
their
populations.

particular,
the
estimates
of
time
devoted
to
night

are
similar
across
studies.
For
the
United

1985
data
indicate
that
individuals
aged
18­
64
averaged
7.8
hours
of
night
sleep
(

A
1998­
1999
New

study
found
that
individuals
aged
12
years
and
older
devoted
8.6
hours

but
did

(

Dollar
Value
of
Time
Losses
This
analysis
uses
compensation
data
to
estimate
the
opportunity
costs
of
lost
work
and
nonwork
time.
There
are
numerous
sources
of
U.
S.
compensation
data,
each
of
which
focuses
on
somewhat
different
data
elements
and
uses
different
approaches
to
data
collection.
The
estimates
developed
for
this
analysis
are
based
on
well­
established
and
frequently
cited
sources
of
national
data,
relying
largely
on
year
2000
data
included
in
the
Statistical
Abstract
of
the
United
States.

The
starting
point
for
the
development
of
these
estimates
is
median
weekly
earnings
for
the
year
2000
for
full
time
workers
($
576
per
week),
as
reported
by
the
United
States
Bureau
of
Labor
Statistics
(
United
States
Census
Bureau,
November
2001,
Table
621).
This
value
is
derived
from
the
Current
Population
Survey
and
includes
wages
and
salaries,
but
not
other
costs
(
e.
g.,
benefits)
paid
by
the
employer.

This
analysis
uses
median
rather
than
average
earnings
as
the
starting
point,
consistent
with
other
EPA
analyses.
16
The
distribution
of
income
in
the
United
States
is
highly
skewed
due
to
the
small
number
of
people
who
are
extremely
highly
compensated,
hence
average
income
is
significantly
higher
than
the
median.
Use
of
the
median
reflects
the
notion
that
the
small
fraction
of
the
U.
S.
population
affected
by
this
rulemaking
are
likely
to
be
better
represented
by
the
median
than
by
the
mean
value,
which
is
closer
to
the
upper
tail
of
the
distribution.

The
next
step
is
conversion
of
this
value
to
earnings
per
hour.
According
to
the
Bureau
of
Labor
Statistics,
individuals
usually
working
full
time
averaged
43.4
hours
per
week
at
work
in
2000
(
United
States
Census
Bureau,
November
2001,
Table
582).
This
means
that
median
earnings
per
hour
averaged
about
$
13.2717.

For
market
work
time,
the
measure
of
opportunity
costs
used
in
this
analysis
is
total
pre­
tax
compensation
from
the
perspective
of
the
employer.
The
earnings
number
reported
above
does
not
reflect
employer
paid
benefits.
To
adjust
this
estimate
upwards
to
reflect
total
compensation,
the
analysis
uses
the
ratio
of
average
wages
and
salaries
to
average
total
compensation,
as
reported
by
the
Bureau
of
Labor
Statistics
for
private
industry
workers
for
2000
(
United
States
Census
Bureau,
December
2000,
Table
701).
These
data
show
that
total
compensation
per
hour
averages
about
1.4
times
wages
and
18
$
22.62
total
compensation
per
hour
/
$
16.25
salary
and
wages
per
hour
=
1.4.
The
earnings
per
hour
estimates
vary
across
data
sources
depending
on
sample
characteristics,
whether
mean
or
median
values
are
reported,
and
other
factors.

19($
576

)
x
($
22.62
total
compensation
per
hour
/
$
16.25
salary
and
wages
per
hour)
=
$
18.47
per
hour.
Although
rounded
data
are
shown
here
and
in
the
text,
full
precision
was
used
in
all
calculations.

20This
median
income
estimates
differ
from
the
earnings
estimates
cited
earlier
because
it
reflects
household
income,
rather
than
individual
earnings,
and
relies
on
a
different
data
source.
With
additional
precision,
the
estimate
of
after
tax
earning
is
$
10.9154;
but
full
precision
was
used
in
all
calculations.

21
A
pioneering
example
of
this
approach
is
Rice
1966;
a
more
recent
example
is
Thamer
et
al.
1998.

Using
these
data
to
adjust
median
hourly
earnings
(
as
reported
above)
leads
to
an
estimate
of
about
$
18.47
per
hour
for
total
compensation19.

For
nonwork
time
(
excluding
sleep),
two
measures
were
used
(
see
Appendix
K
for
more
background
on
these
measures).
The
first
measure,
used
in
the
Enhanced
Cost
of
Illness
(
Enhanced
COI),
is
after­
tax
earnings,
i.
e.,
the
"
take
home"
pay
of
the
median
working
individual.
This
analysis
relies
on
Current
Population
Survey
data
on
household
income
before
and
after
taxes
(
United
States
Census
Bureau,
March
2002)
to
determine
the
percent
of
earnings
paid
as
taxes.
In
2000,
the
median
before
tax
income
was
$
42,151
and
median
after
tax
income
was
$
34,667.20
Thus,
after
tax
income
was
about
82.2
percent
of
the
pre­
tax
amount.
Applying
these
data
to
median
hourly
earnings
leads
to
estimated
after
tax
earnings
of
about
$
10.92
per
hour.
This
figure
was
used
to
value
both
lost
unpaid
work
time
and
lost
leisure
time
in
the
Enhanced
COI.
It
was
also
a
component
of
the
value
of
the
lost
caregiver
time.

A
second
measure
was
used
to
value
lost
unpaid
work
time
for
the
Traditional
COI.
The
value
is
half
of
the
after­
tax
wage,
or
about
$
5.46
per
hour.
The
use
of
50
percent
of
the
wage
rate
is
consistent
with
the
common
practice
in
the
human
capital
literature
of
valuing
nonmarket
work
time
at
the
market
rate
for
domestic
workers21.
This
literature
uses
replacement
costs
as
a
measure
of
the
productivity
of
nonmarket
work,
rather
than
focusing
on
the
opportunity
costs
(
or
utility
loss)
for
the
individual
who
chooses
to
engage
in
nonmarket
work.
The
median
weekly
earnings
of
private
household
workers
in
the
service
industry
were
$
261
per
week
in
2000,
about
45
percent
of
the
median
weekly
earnings
of
$
576
for
all
workers
(
U.
S.
Census
Bureau
Table
621).
Private
household
workers
include
childcare
workers,
cleaners,
and
servants.
The
Traditional
COI
does
not
include
values
for
lost
leisure
time
or
lost
productivity.

Lost
Productivity
(
Enhanced
COI
Only)

Time
losses
associated
with
nonfatal
cases
of
cryptosporidiosis
may
include
(
1)
a
reduction
in
time
(
hours)
engaged
in
normal
activities
and
(
2)
an
additional
loss
of
productivity
(
or
effectiveness)
that
occurs
even
when
the
ill
individual
continues
to
engage
in
normal
activities.
Reductions
in
time
(
or
hours)
would
result,
for
example,
when
an
ill
individual
spends
time
on
doctor
visits,
bed
rest,
or
in
the
hospital
rather
than
engaging
in
normal
work
and
nonwork
activities.
Additional
losses
in
productivity
occur
when
the
individual
continues
to
engage
in
normal
activities,
but
is
less
productive
or
finds
them
less
enjoyable
due
to
illness.
In
this
Economic
Analysis,
the
Enhanced
COI
includes
estimates
for
lost
productivity,
but
the
Traditional
COI
does
not.

The
estimate
used
for
lost
productivity
assumes
that
time
spent
in
normal
activities
is
30
percent
less
productive
than
it
would
be
normally,
i.
e.,
an
individual
produces
30
percent
less
per
unit
of
time
engaged
in
market
or
nonmarket
work,
and
is
30
percent
less
effective
at
leisure
activities.
Furthermore,
the
best
estimate
assumes
that
the
dollar
value
(
i.
e.,
the
utility
loss,
estimated
based
on
opportunity
costs)
of
this
reduction
is
equal
to
the
reduction
in
productivity
multiplied
by
the
relevant
dollar
per
hour
value
(
from
Exhibit
L.
9
above).
In
other
words,
the
30
percent
loss
in
productivity
is
multiplied
by
$
64.75
per
day
to
estimate
the
value
of
reduced
productivity
while
at
work,
and
by
$
23.83
per
day
to
estimate
the
value
of
reduced
productivity
while
engaged
in
unpaid
work,
and
by
$
112.56
per
day
for
leisure
activities.
As
noted
earlier,
the
value
of
sleep
time
is
conservatively
estimated
as
"
zero"
as
the
effect
of
illness
on
sleep
time
is
not
quantified
in
this
analysis.

The
30
percent
productivity
loss
is
based
on
Harrington
et
al.
(
1991),
which
reports
the
results
of
a
survey
of
individuals
affected
by
a
1983
giardiasis
outbreak
in
Luzerne
County,
Pennsylvania.
In
addition
to
asking
questions
about
missed
work
time,
the
Harrington
et
al.
survey
asks:

"
If
you
went
to
work
during
this
illness,
did
your
illness
affect
your
ability
to
work
as
hard
as
you
usually
do
at
your
job?"
(
Harrington
et
al.
(
1991),
p.
126)

This
question
was
followed
by
a
bounded
multiple
choice
question
regarding
the
percent
decrease
in
normal
capacity
while
working
with
the
illness.
The
researchers
found
that
respondents
identified
as
workers
reported
a
30.4
percent
loss,
while
those
identified
as
homemakers
reported
a
34.0
percent
loss
(
Harrington
et
al.
(
1991),
p.
103).
For
the
analysis
of
cryptosporidiosis
contained
in
this
report,
these
values
are
rounded
to
30
percent.
These
losses
are
to
the
employer
for
paid
work
time,
and
to
the
individual
for
nonpaid
work.

In
addition
to
applying
this
30
percent
loss
rate
to
market
and
nonmarket
work
time,
the
Enhanced
COI
analysis
applies
this
rate
to
leisure
time.
The
Harrington
et
al.
survey
asked
respondents
whether
their
leisure
activities
changed
as
a
result
of
the
illness,
as
well
as
whether
the
illness
required
them
to
change
their
normal
routines.
While
percentage
losses
were
not
requested
for
time
engaged
in
leisure
activities
while
ill,
the
survey
results
did
confirm
that
these
activities
were
altered
as
a
result
of
the
illness.
While
these
changes
in
leisure
activities
are
partially
captured
in
the
analysis
of
time
losses
(
i.
e.,
decreased
hours
spent
in
work,
nonwork,
and
leisure
activities),
it
appears
reasonable
to
assume
that
the
utility
or
pleasure
associated
with
those
leisure
activities
that
are
pursued
while
ill
is
also
reduced
as
a
result
of
the
illness.

The
effects
of
giardiasis
are
very
similar
to
the
effects
of
cryptosporidiosis,
and
a
review
of
the
literature
failed
to
identify
any
other
recent
U.
S.
studies
that
report
productivity
losses
for
similar
gastrointestinal
illnesses.
The
Harrington
et
al.
estimate
of
an
approximately
30
percent
reduction
appears
reasonable
based
on
review
of
studies
estimating
productivity
losses
due
to
other
illnesses,
as
discussed
in
more
detail

Year­

Estimates
for
Enhanced
and
Traditional
Costs
of
Illness
Using
data
presented
in
Appendix
C
and
Exhibit
C.
12,
the
data
presented
in
Exhibit
L.
10
are
adjusted
to
reflect
increases
in
income
growth
and,
therefore,
the
value
of
time,
each
year
to
2027.
This
increase
in
income
growth
means
that
the
cost
of
an
illness
would
increase
over
time
because
lost
time
is
recovered
by
wage
rates
or
their
equivalent.
The
same
per­
capita
GDP
values
used
to
value
mortality
in
the
future
(
and
presented
in
Exhibit
C.
12),
are
employed
to
compute
income
growth
between
the
future
year
and
the
year
2000
(
the
baseline
year
for
cost
of
illness
calculations).
Using
the
data
from
2000
as
the
base
year,
the
lost
time
portion
of
the
cost
of
illness
is
adjusted
to
reflect
the
annual
percent
change
in
income
(
the
real
GDP
per
capita).
In
the
benefits
model,
the
cases
avoided
in
each
year
are
valued
as
shown
in
Exhibit
L.
11
(
using
unrounded
data).

Dose­
Response
Infectivity
Analysis
The
U.
S.
Environmental
Protection
Agency
(
EPA
or
the
Agency)
revised
its
dose­
response
infectivity
analysis
in
response
to
the
report
produced
from
the
December
12,
2001,
Science
Advisory
Board
(
SAB)
meeting.
The
SAB
report
recommended
removing
the
results
of
the
experiment
using
the
UCP
isolate
of
Cryptosporidium
parvum
from
the
dose­
response
analysis,
based
on
concerns
about
the
age
of
the
isolate
and
its
poor
performance
in
cell
culture
assays.
Based
on
discussions
with
Dr.
Cynthia
Chappell,
author
of
the
study
reporting
the
UCP
results,
EPA
decided
to
run
the
analysis
in
a
way
to
combine
distributions
that
included
and
excluded
the
UCP
data.

With
only
two
(
IOWA
and
TAMU
(
Texas
A&
M
University)
Cryptosporidium
isolates)
or
three
(
IOWA,
TAMU,
and
UCP
isolates)
studies,
model
uncertainty
is
a
concern.
To
address
model
uncertainty,
SAB
statisticians
recommended
using
a
50/
50
mix
of
two
models;
lognormal
and
log­
t
(
3
degrees
of
freedom).
Because
the
exponential
dose­
response
parameter
r
is
a
probability,
lognormal
and
log­
t
distributions
would
have
to
be
constrained
to
less
than
0
(
ln(
1)
=
0).
To
overcome
the
technical
difficulty
posed
by
this
truncation,
EPA
uses
logit
rather
than
natural
logarithms.
The
two
models
are
logit­
normal
and
logit­
t.
For
the
logit­
normal
model,
logit(
r)
is
normally
distributed
with
parameters
mu
and
sigma.
For
the
logit­
t
model,
[
logit(
r)
­
mu]
/
sigma
is
t
distributed
with
3
degrees
of
freedom.

Thus,
the
analysis
combines
the
results
of
four
models
(
Exhibit
N.
1).
The
analysis
samples
results
from
each
of
these
four
models
equally
during
iterations
in
the
Monte
Carlo
benefits
model.

This
is
accomplished
by
using
the
program
BUGS
to
estimate
model
parameters
(
mu,
sigma)
for
each
model.
The
program
produced
a
large
sample
(
10,000
mu­
sigma
pairs)
for
each
model.
For
each
mu­
sigma
pair,
the
expectation
of
r
(
E(
r))
was
computed
for
use
in
the
benefits
model.

In
each
outer
loop
(
uncertainty)
of
the
benefits
model,
a
single
value
of
E(
r)
is
selected.
Daily
probability
of
infection
is
then
computed
as
1
­
e­
E(
r)*
vol*
V*
C,
where
vol
is
the
volume
of
water
ingested
during
a
day
(
liters),
V
is
the
infectivity
of
environmental
oocysts
(
compared
to
the
infectivity
of
dosestudy
oocysts),
and
C
is
the
finished
water
concentration
(
oocysts
per
liter).
The
values
of
E(
r)
are
means,
and
thus
the
model
only
includes
uncertainty
in
E(
r),
and
no
variability.

Analysis
Models
The
probability
of
infection
depends
on
the
dose
and
the
isolate's
dose­
response
parameter,
r:

Pr{
infection
|
dose}
=
1
­
e
­
r*
dose
Subjects
given
the
same
dose
independently
share
the
same
probability
of
infection.
Given
S
subjects
at
dose
D,
the
number
actually
infected
is
a
binomial
random
variable
with
parameters
S
and
(
1
­
e
­
r*
D).

Different
isolates
have
different
dose­
response
parameters.
Only
two
(
or
three)
isolates
were
studied;
IOWA
and
TAMU
(
and
UCP).
Their
dose­
response
parameters
are
called
IOWA,
TAMU,
and
UCP,
respectively.
These
parameters
are
assumed
to
represent
a
much
larger
population
of
doseresponse
parameters.
Under
the
logit­
normal
model
(
MODEL
1
and
MODEL
1b),
the
distribution
of
logit(
r)
is
normal
with
unknown
parameters
(
mu,
phi),
where
phi
is
precision,
1/
sigma2.
Under
the
logit­
t
model
(
MODEL
2
and
MODEL
2b)
the
distribution
of
[
logit(
r)­
mu]
/
phi1/
2
is
Student's
t
with
3
degrees
of
freedom.

Prior
to
reviewing
the
data,
not
much
could
be
known
about
parameters
mu
and
phi
for
these
models.
It
would
be
very
surprising
if
mu
were
to
lie
outside
the
range
(­
14.2,
2.2)
or
if
phi
were
to
lie
outside
the
range
[
0.04,
100].
If
mu
were
less
than
­
14.2
(
eventually
rounded
to
­
14
in
the
model),
then
the
median
value
of
r
would
be
less
than
10­
6.
If
mu
were
greater
than
2.2,
then
the
median
value
of
r
would
exceed
0.9.
It
would
not
be
credible
for
the
median
value
for
r
(
the
probability
of
infection,
given
exactly
one
oocyst
ingested)
to
be
outside
the
range
(
10­
6,
0.9).

Regarding
phi,
it
would
be
unlikely
that
a
95
percent
interval
for
logit(
r)
could
be
much
wider
than
logit(
10­
5)
to
logit(
0.5).
This
interval
is
11.513
logit
units
wide.
If
a
2­
sigma
interval
(
containing
68.3
percent
of
the
probability
mass)
is
10
logit
units
wide,
the
corresponding
precision,
phi,
would
be
0.04.
At
the
other
extreme,
it
would
not
be
surprising
if
the
precision
were
very
large.
A
precision
of
100
would
correspond
to
a
standard
deviation
of
1/
10,
which
would
require
the
relative
standard
deviation
of
r
to
be
about
10
percent.
Given
the
differences
in
isolate
sources,
history,
and
handling,
it
would
not
be
credible
that
the
standard
deviation
of
r
could
be
smaller
than
this.
Therefore,
the
feasible
range
for
phi
is
(
0.04,
100).

Within
these
ranges,
(­
14,
and
2.2)
for
mu
and
(
0.04,
100)
for
phi,
it
is
assumed
that
mu
and
sigma
could
fall
anywhere.
Rather
than
construct
a
more
complex
prior,
the
model
uses
uniform
priors
on
these
ranges.

The
program
code
for
BUGS
for
one
of
the
models
(
1b)
is
shown
below
as
an
example.
The
code
for
MODEL
2b
is
almost
identical.
The
difference
is
that
MODEL
2b
defines
a
as
dt(
mu,
phi,
df)
and
c
as
dt(
mu,
phi,

with
df
=

Performance
The
output
of
the
models
are,
as
expected,
autocorrelated
between
close
runs.
Thinning
the
resulting
data
essentially
removes
this
autocorrelation.
To
help
determine
the
needed
degree
of
thinning,
autocorrelation
plots
for
the
hyperparameters
mu
and
phi
were
prepared,
and
these
plots
are
shown
in
Exhibits
N.
5
and
N.
6
using
MODEL2
as
an
example.
These
plots
based
on
a
sample
size
of
100,000
without
thinning.

for

for

As
can
be
seen,
autocorrelation
is
not
noticeable
for
phi
after
a
lag
of
about
20.
Thus,
thinning
to
1
in
20
(
discarding
19
of
every
20
mu­
phi
pairs),
the
program
produced
a

phi
pairs
with
negligible
autocorrelation.
Scatterplots
(
not
shown)
of
(

also
confirmed
good
mixing.

The
program
required
200
thinned
runs
for
adapting,
so
the
first
200
(
mu,

pairs
of
each
analysis
were
discarded
and
not
included
in
the
final

Appendix
O
Assigning
LT2ESWTR
Costs
and
Benefits
This
appendix
presents
data
used
to
calculate
the
costs
and
benefits
associated
with
full
implementation
of
the
LT2ESWTR.
In
order
to
extract
cost
and
benefit
data
from
the
model
and
present
them
in
comparable
terms,
it
is
necessary
to
calculate
the
annualized
value
of
all
costs
and
benefits
over
the
lifetime
of
the
implementation
schedule.
LT2ESWTR
implementation
will
occur
over
several
years
as
States
and
public
water
systems
(
PWSs)
learn
the
requirements
of
the
rule,
train
their
staffs,
perform
initial
monitoring,
and
add
any
treatment
necessary
to
comply
with
the
rule.
A
25­
year
horizon
is
used
for
this
economic
analysis
(
EA)
and
the
EA
for
the
Stage
2
Disinfection
Byproducts
Rule.
This
time
frame
accounts
for
both
the
20­
year
life
for
technologies
considered
in
this
analysis,
and
the
5­
year
period
that
systems
have
to
comply
with
treatment
requirements.

O.

Benefit
and
Cost
Distributions
Both
costs
and
benefits
are
presented
as
distributions
of
values.
The
benefits
model
calculates
one
distribution
for
each
of
the
3
occurrence
data
sets
 
Information
Collection
Rule
(
ICR),
Information
Rule
Supplemental
Survey
Large
(
ICRSSL),
and
Information
Rule
Supplemental

(

The
cost
model
generates
5
distributions
from
the
3

data
sets
 
3
representing
the
means
of
each
data
set
and
2
representing
the

illustrates
the
five
cost
distributions
(
ICR,

that
were
generated
and
what
they
represent
in

to

Derivation
of
Cost
Distributions
The
three
primary
cost
distributions;
ICR,
ICRSSL,
and
ICRSSM,
are
derived
from
the
binning
percentage
associated
with
the
mean
of
each
occurrence
distribution
(
for
binning
percentages
see
section
4.5.6).
To
more
fully
describe
the
uncertainty
surrounding
occurrence,
two
more
distributions
were
considered.
The
Low
cost
distribution
is
generated
from
the
binning
percentage
at
the
5th
percentile
of
the
modeled
ICRSSL
occurrence
distribution.
The
High
cost
distribution
is
generated
from
the
95th
percentile
of
the
modeled
ICR
occurrence
distribution.
This
appendix
presents
the
means,
5th
percentiles,
and
95th
percentiles
of
all
five
cost
distributions
to
characterize
costs
(
Exhibits
3
and
4).
Benefits
are
characterized
by
three
distributions
(
Exhibits
5
and
6).

O.
2
Benefit
and
Cost
Values
Costs
and
benefits
models
output
values
that
are
representative
of
the
value
they
would
have
if
they
were
all
incurred
immediately.
These
values
are
referred
to
as
the
value
at
full
implementation
throughout
this
appendix.
In
order
to
be
able
to
compare
these
values
properly,
the
costs
and
benefits
must
be
distributed
over
the
period
in
which
they
are
expected
to
occur
and
the
costs
must
be
brought
into
comparable
terms.

Exhibits
O.
2a­
c
show
the
schedules
over
which
the
various
components
of
costs
and
benefits
are
distributed
(
for
implementation
and
monitoring,
treatment,
and
State,
respectively).
Most
of
the
cost
numbers
are
one­
time
costs
that
are
incurred
only
once
during
the
25­
year
period
examined.
The
data
given
in
Exhibits
O.
2a­
c
are
the
percentage
of
the
value
at
full
implementation
expected
to
be
incurred
in
the
given
year.
In
general,
it
is
assumed
that
such
expenses
are
evenly
distributed
over
the
time
frame

For
example,
E.
coli
monitoring
for
large
systems
must
be
completed
in
one
year,
so
100
percent
of
these
costs
is
applied
to
one
year.
Installation
of
covers
or
treatment
for
uncovered
reservoirs,
however,
has
a
five
year
period
in
which
to
comply.
Therefore,
it
is
assumed
that
20
percent
of
the
costs
will
be
incurred
in
each
of
those
five
years.

Operation
and
maintenance
(
O&
M)
and
compliance
monitoring
costs,
as
well
as
benefits,
are
annual
values
expected
to
be
incurred
every
year
once
treatment
is
installed
and
operational.
The
value
at
full
implementation
represents
the
annual
cost
once
all
plants
have
treatment
fully
installed
and
operational.
As
shown
in
Exhibit
O.
2b,
the
schedules
for
O&
M
costs
and
benefits
are
delayed
one
year
from
the
treatment
schedule
to
allow
for
installation
and
implementation
of
the
technology.

Once
the
costs
and
benefits
are
distributed
across
the
25­
year
time
frame,
they
must
be
brought
into
comparable
terms.
This
is
done
in
two
ways.
The
first
is
by
expressing
the
values
as
present
values
using
a
social
discount
rate.
The
second
is
by
taking
the
present
value
and
annualizing
it.

The
present
value
of
a
cost
or
benefit
incurred
in
a
given
year
is
given
by
the
following
formula:

PV
=
V(
t)
/
(
1
+
R)
t
Where:
t
=
The
number
of
years
from
the
reference
period
R
=
Social
discount
rate
V(
t)
=
The
cost
occurring
t
years
from
the
reference
period
The
total
present
value
of
a
given
component
is
then
the
sum
of
the
present
value
calculated
for
each
year
from
1
to
25.

The
formula
for
converting
the
present
value
into
an
annualized
value
is
as
follows:

A
=
PV*
R(
1
+
R)
25/[(
1
+
R)
25
­
1]

Where:
A
=
Annualized
value
PV
=
Present
value
R
=
Social
discount
rate
Exhibits
O.
3
through
O.
6
show
the
nominal
(
value
at
full
implementation,
undiscounted),
present
value
(
Year
2000$),
and
annualized
value
for
each
component
of
costs
and
benefits.
The
present
and
annualized
values
are
calculated
at
both
a
3
and
7
percent
social
discount
rate.

For
all
treatment
and
benefit
values,

exhibits

Introduction
and
Summary
Chapter
5
and
Appendices
K
and
L
of
this
Economic
Analysis
(
EA)
describe
the
approach
and
calculations
used
to
determine
dollar
values
for
reductions
in
nonfatal
cases
of
cryptosporidiosis.
That
approach
uses
two
point
estimates,
the
Traditional
and
Enhanced,
for
the
cost
of
illness
(
COI)
and
relies
on
single
point
values
for
the
key
inputs.
This
appendix
tests
the
sensitivity
of
the
results
to
alternative
values
for
two
of
the
key
underlying
inputs
to
the
Enhanced
COI.
The
first
input
is
the
value
of
nonmarket
time.
The
second
is
the
percentage
productivity
loss
that
may
accompany
an
illness,
which
is
applied
to
the
time
that
someone
is
ill
but
is
at
least
partly
productive.
These
days
are
assumed
to
be
the
difference
between
the
duration
of
the
entire
illness
less
the
"
days
lost"
due
to
the
illness.
For
each
of
these
two
inputs
to
the
Enhanced
COI,
low
and
high
estimates
are
selected,
and
the
effects
of
using
those
different
values
on
the
net
benefits
and
the
selection
of
the
Preferred
Alternative
are
presented.
It
should
be
noted
that
the
Low
COI
value
used
in
this
sensitivity
analysis
is
very
roughly
about
two­
thirds
the
value
used
for
the
Enhanced
COI,
and
thus
is
also
(
very
roughly)
about
twice
the
value
used
for
the
Traditional
COI.

The
overall
result
of
using
the
Low
Value
for
Cost­
of­
Illness
(
COI)
is
that
Alternative
A4
becomes
somewhat
more
competitive
alternative
relative
to
the
Preferred
Alternative
(
A3),
although
not
as
strongly
so
as
when
using
the
Traditional
COI.
Alternative
A4
does
not
excel
under
every
condition,
and
the
competitiveness
of
Alternative
4
is
undercut
somewhat
given
that
there
exist
unquantified
benefits.
The
Preferred
Alternative
continues
to
meet
all
threshold
criteria,
even
when
the
Low
Value
for
COI
is
used.

The
overall
result
of
using
the
High
Value
for
COI
is
that
Alternative
A3
continues
to
be
the
strongest
alternative
across
all
the
relevant
considerations.
The
consideration
of
these
two
alternative
values
for
the
Enhanced
COI
strengthens
the
basis
for
selecting
A3
as
the
Preferred
Alternative.
The
sensitivity
analysis
shows
Alternative
A3
to
be
robust
in
the
face
of
a
range
of
alternative
values.

P.

Alternative
Values
for
the
Dollar
Value
of
Nonwork
Time
Losses
and
the
Percent
Decrease
in
Productivity
As
discussed
previously
in
Appendix
L,
the
estimate
for
the
Enhanced
COI
includes
values
for
both
lost
time
and
lost
productivity.
While
the
determination
of
the
value
of
lost
work
time
appears
relatively
straightforward,
the
valuation
of
nonwork
losses
is
subject
to
two
major
sources
of
uncertainty:
(
1)
individuals
may
value
these
losses
at
a
rate
significantly
higher
or
lower
than
the
post­
tax
median
wage;
and
(
2)
the
reported
amount
of
time
lost
may
include
some
time
spent
on
activities
that
represent
an
incomplete
loss
of
utility;
e.
g.,
some
of
this
time
may
be
spent
reading
rather
than
coping
with
a
bout
of
diarrhea.
There
would
be,
of
course,
some
offsetting
utility
losses
from
the
discomfort
and
stress
of
being
sick.
The
values
used
in
the
sensitivity
analysis
test
the
effect
of
each
of
these
sources
of
uncertainty
on
the
value
of
lost
nonwork
time.
1
Median
wage
data
is
used
instead
of
data
on
marginal
rates
due
to
difficulties
in
determining
the
latter.
It
is
unclear
whether
this
approach
under­
or
overstates
the
actual
value
of
time
trade­
offs
at
the
margin.

Analysis

the
LT2ESWTR
Proposal
June

P­
2
The
survey
question
used
to
determine
the
percentage
decrease
in
productivity
refers
to
productivity
while
performing
normal
activities.
While
this
rate
of
decrease
appears
consistent
with
the
findings
from
studies
of
other
illnesses,
it
is
possible
that
the
decrease
in
the
productivity
of
nonwork
time
may
be
greater
or
less
than
this
estimate.
The
values
used
in
these
two
components
of
the
sensitivity
analysis
are
discussed
in
more
detail
below.

P.
2.1
Dollar
Value
of
Nonwork
Time
Losses
The
sensitivity
analysis
of
the
dollar
value
of
nonwork
time
losses
uses
a
high
value
of
150
percent
of
the
Enhanced
COI
for
nonwork
time
loss,
and
a
low
value
of
50
percent
of
the
Enhanced
COI.
These
bounds
represent
the
effect
of
(
1)
assuming
that
all
nonwork
time
lost
is
valued
at
a
rate
higher
than
under
the
Enhanced
COI
and
(
2)
assuming
that
some
of
the
nonwork
time
lost
is
an
incomplete
loss
of
utility.

The
Enhanced
COI
for
the
value
of
nonwork
time
is
based
on
median
post­
tax
wages.
This
estimate
reflects
the
assumption
that
the
opportunity
cost
of
nonwork
time
is,
at
a
minimum,
the
wages
foregone.
In
other
words,
an
individual
who
chooses
to
engage
in
activities
other
than
market
work
does
so
because,
at
the
margin,
the
utility
(
productivity
plus
any
additional
enjoyment)
from
nonmarket
work
or
leisure
is
greater
than
the
utility
gained
from
market
work.
Therefore,
that
individual
must
value
a
marginal
hour
of
his
or
her
nonwork
time
at
a
rate
at
least
equal
to
the
marginal
net
wage
per
hour
he
or
she
could
have
earned
in
the
job
market.
For
many
individuals,
the
median
post­
tax
wage
may
understate
the
value
of
nonwork
time.
1
This
assumption
is
consistent
with
the
fact
that
many
workers
demand
a
rate
higher
than
their
hourly
wage
to
work
additional
hours.
Hence
the
high
value
used
in
the
sensitivity
analysis
is
derived
from
information
on
overtime
pay.
The
Fair
Labor
Standards
Act
states
that
workers
covered
by
its
provisions
must
be
paid
at
a
rate
not
less
than
one
and
one­
half
times
their
regular
pay
for
work
over
40
hours
in
1
work
week
unless
specifically
exempted
(
U.
S.
Department
of
Labor
undated).
Applying
this
"
time­
and­
a­
half"
standard
to
the
recommended
value
of
$
10.91
per
hour
for
nonwork
time
leads
to
a
high
value
of
$
16.37
per
hour.

The
low
value
for
nonwork
time
reflects
the
fact
that
individuals
may
gain
some
utility
from
the
activities
they
pursue
while
ill,
hence
the
loss
is
not
complete.
The
question
used
to
determine
time
losses
refers
to
changes
in
normal
activities;
however,
in
some
cases
the
activities
that
replace
the
normal
activities
may
have
some
positive
value.
For
example,
during
the
period
reported
as
lost
time,
an
individual
may
substitute
reading
a
book
for
playing
golf,
in
a
case
where
golf
would
have
been
the
preferred
activity
if
that
person
were
well.
The
reading
time
presumably
has
some
positive
value
to
that
individual
that
is
less
than
the
value
of
golfing.
Other
portions
of
the
time
reported
as
lost,
e.
g.,
that
spent
coping
with
a
bout
of
diarrhea,
may
have
close
to
zero
value
and
hence
represent
a
relatively
complete
loss
of
utility.
Thus,
while
the
loss
for
time
spent
in
the
latter
condition
(
a
bout
of
diarrhea)
may
be
complete
(
i.
e.,
equal
to
the
post­
tax
wage
rate)
the
loss
in
the
former
case
(
reading
rather
than
golfing)
would
be
partial
(
i.
e.,
equal
to
some
fraction
of
the
post­
tax
wage
rate).
The
total
amount
of
lost
nonwork
2
Travel
cost
studies
are
focused
on
the
costs
(
or
negative
impacts)
associated
with
traveling
longer
distances.
They
assume
that
travel
time
has
some
positive
effects
(
or
utility);
otherwise,
time
costs
would
be
valued
at
the
full
wage
rate
(
i.
e.,
as
a
complete
loss).

3
A
pioneering
example
of
this
approach
is
Rice
1966;
a
more
recent
example
is
Thamer
et
al.
1998.

time
thus
may
include
both
some
time
that
is
a
total
loss
and
some
that
is
a
partial
loss,
so
that
the
average
loss
would
be
less
than
the
Enhanced
COI
(
i.
e.,
than
the
post­
tax
wage
rate).

Only
limited
research
is
available
that
is
applicable
to
determining
this
fractional
value.
Perhaps
the
most
relevant
available
research
is
that
which
focuses
on
the
value
of
travel
time
in
the
context
of
recreational
demand
studies.
These
revealed
preference
studies
use
information
on
the
costs
associated
with
the
recreational
use
of
different
sites
to
estimate
willingness
to
pay
for
various
types
of
recreational
experiences,
and
the
time
spent
traveling
to
alternate
sites
is
one
part
of
these
costs.
These
studies
typically
value
time
spent
traveling
to
a
recreation
site
at
a
fixed
fraction
of
the
individual's
wage
rate;
this
represents
the
disutility
associated
with
travel.
2
The
precise
fraction
of
the
wage
rate
used
to
value
travel
time
costs
has
ranged
from
zero
to
one
in
published
empirical
studies.
Recently,
it
has
become
somewhat
standard
practice
to
use
one­
third
the
individual's
wage
rate
as
a
proxy
for
the
value
of
travel
time,
although
there
is
no
strong
theoretical
basis
for
this
assumption
(
Shaw
and
Feather
1999).
Rather
than
assuming
a
particular
value
for
time
costs,
a
few
researchers
have
estimated
the
value
of
time
empirically.
For
example,
McConnell
and
Strand
(
1981)
find
that
the
value
of
travel
time
is
approximately
60
percent
of
the
wage
rate,
while
some
of
Larson's
work
implies
that
the
value
of
travel
time
is
approximately
16
percent
of
the
wage
rate
(
Larson
1993).

The
use
of
one­
third
the
wage
rate
in
travel
cost
recreation
studies
appears
to
have
its
origin
within
the
transportation
economics
literature,
and
in
particular
from
early
reviews
conducted
by
Beesley
(
1965)
and
Cesario
(
1976).
More
recent
reviews
have
provided
limited
support
for
this
assumption.
Bruzelius
(
1979)
finds
that
individuals
value
in­
vehicle
time
for
work
trips
at
20
to
30
percent
of
the
wage
rate,
while
reviews
by
Small
(
1992)
and
Waters
(
1992)
have
suggested
that
the
consensus
value
is
near
50
percent
of
the
wage
rate.

Unfortunately,
these
studies
are
focused
on
a
particular
type
of
time
use,
i.
e.,
for
travel.
The
resulting
estimates
are
therefore
not
necessarily
applicable
to
the
types
of
time
losses
associated
with
cryptosporidiosis,
which
may
affect
all
types
of
nonwork
time,
including
a
variety
of
leisure
and
nonmarket
work
activities.
However,
they
suggest
that
50
percent
of
the
wage
rate
is
within
the
range
of
reasonable
estimates
for
activities
(
such
as
travel)
that
have
both
enjoyable
and
unenjoyable
aspects.
Applying
this
50­
percent
reduction
standard
to
the
Enhanced
COI
of
$
10.91
per
hour
for
nonwork
time
leads
to
a
low
value
of
$
5.46
per
hour.

The
use
of
50
percent
of
the
wage
rate
is
also
consistent
with
the
common
practice
in
the
human
capital
literature
of
valuing
nonmarket
work
time
at
the
market
rate
for
domestic
workers3.
This
literature
uses
replacement
costs
as
a
measure
of
the
productivity
of
nonmarket
work,
rather
than
focusing
on
the
opportunity
costs
(
or
utility
loss)
for
the
individual
who
chooses
to
engage
in
nonmarket
work.

median
weekly
earnings
of
private

workers
in

For
the
Enhanced
COI,
the
value
of
time
losses
assumes
that
time
spent
in
normal
activities
while
ill
is
30
percent
less
productive
than
it
would
be
in
the
absence
of
illness.
This
estimate
of
30
percent
appears
reasonable
based
on
review
of
other
studies
valuing
productivity
losses
due
to
illness.

The

of
the

reported
in

Some
of
these
studies
focus
on
lost
work
time,
while
others
look
more
broadly
at
effectiveness
across
a
number
of
daily
activities.
Studies
of
other,
potentially
more
severe
illnesses
(
e.
g.,
cancer
and
heart
disease)
generally
report
greater
productivity
losses
(
for
example,
see
Hartunian
et
al.
1981).

The
close
correlation
between
symptomatic
effects
and
treatment
of
giardiasis
and
cryptosporidiosis
along
with
the
support
for
the
estimated
productivity
decrease
gathered
from
the
literature
review,
suggest
that
it
is
most
appropriate
to
use
a
narrow
range
of
low
to
high
values
for
the

Using
these
COI
values
in
the
sensitivity
analysis
requires
several
steps.
First,
the
values
are
applied
to
the
cases
of
illness
avoided
each
year.
Those
year­
to­
year
amounts
are
discounted
to
present
values
(

and
then
annualized
over
25
years.

The

is
also
proportional,
but
the

The
previous
section
reports
the
results
of
using
alternative
values
for
the
COI
on
the
amount,
or
level,
of
total

The
results
follow
expected
patterns:
lower
estimates
for
these
key
variables
yield
lower
overall
benefits,
and
higher
estimates
for
those
variables
produce
higher
estimates
of
total
benefits.
The
following
sections
are
more
meaningful
in
that
they

COI

produce

conclusions.
That
is,
do
the
Regulatory
Alternatives
still
meet
economic
threshold
criteria?
What
do
comparisons
between
alternatives
reveal?
The
following
sections
largely
follow
the
pattern
of
comparisons
and
tests
developed
in
Chapter
8,
Net
Benefits.

The
first
threshold
test
is
whether
the
Regulatory
Alternatives
continue
to
be
likely
to
have
positive
net
benefits.
Exhibit
P.
10
compares
the
mean
net
benefits
computed
using
each
of
the
three
COI
estimates
with
the
maximum
net
benefits
shown
in
bold.
Alternatives
A2,
A3
(
the
Preferred
Alternative),
and
A4
all
have
positive
net
benefits
under
all
circumstances.
Alternative
A1
has
consistently
positive
net
benefits
only
using
a
high
value
for
COI
or
using
occurrence
distributions
derived
from
the
ICR
data
set.

Maximum
Net
Benefits
Identifying
the
maximum
net
benefits
among
the
regulatory
alternatives
is
a
first
step
in
a
comparative
analysis
of
regulatory
alternatives.
Considering
the
combinations
of
occurrence
data
sets,
low
and
high
COI
values,
and
discount
rates,
the
Preferred
Regulatory
Alternative
(
A3)
had
the
maximum
net
benefits
of
the
alternatives
for
over
half
of
the
combinations.
However,
the
differences
are
often
slight
among
the
three
regulatory
alternatives
(
A2,
A3,
and
A4)
(
Exhibit
P.
10).
The
range
from
the
high
to
the
low
of
A2,
A3,
and
A4
is
never
more
than
11
percent
for
all
of
the
combinations.

Incremental
Net
Benefits
The
patterns
of
incremental
benefits
discussed
in
Chapter
8
are
based
on
the
Enhanced
COI.
Exhibit
P.
11
below,
expands
that
exhibit
to
also
show
the
patterns
derived
from
using
the
Low
and
High
values
for
COI.
Rule
alternatives
can
also
be
compared
on
the
basis
of
their
incremental
net
benefits.
Generally,
the
goal
of
an
incremental
analysis
is
to
identify
the
regulatory
option
where
incremental
benefits
most
closely
equal
incremental
costs.
This
point
most
often
lies
between
two
alternatives
and
given
the
uncertainty
around
the
mean
cost
and
benefit
estimates,
either
is
likely
to
be
closest
to
that
optimum
point.
Under
all
but
two
conditions
using
the
Low
and
High
COI
estimates,
the
Preferred
Alternative
is
one
of
the
bounding
alternatives.
The
sensitivity
of
mean
benefit
estimates
in
this
analysis
is
further
illustrated
by
the
ranking
analysis
presented
in
section
P.
3.5.

Enhanced

Ranking
of
Alternative
by
Net
Benefits
In
Chapter
8,
the
sensitivity
of
the
ranking
of
each
of
the
regulatory
alternatives
in
terms
of
net
benefits
is
shown
(
Exhibits
8.15
and
8.16).
Those
exhibits
show
the
sensitivity
of
those
rankings
to
alternative
benefit
estimates,
and
focus
on
how
unquantified
benefits,
if
they
could
be
quantified
and
included,
might
alter
the
conclusions
reached
about
the
relative
preference
of
regulatory
alternatives.
These
exhibits
hold
the
number
of
illness
and
deaths
due
to
cryptosporidiosis
constant.

The
exhibits
are
also
useful
for
testing
the
sensitivity
of
alternative
values
of
the
COI.
The
"
1"
on
the
x­
axis
represents
the
Enhanced
COI.
These
exhibits
are
shown
again
below,
but
with
lines
added
to
indicate
the
multiples
corresponding
to
the
Low
COI
and
High
COI
values
of
estimated
mean
benefits.

Cost
Effectiveness
 
Traditional
Approach
In
Chapter
8,
Exhibit
8.17
compares
the
range
of
costs
for
the
mean
benefit
levels
of
each
alternative.
Below,
Exhibits
P.
12
and
P.
13
repeat
that
exhibit,
but
adds
two
lines
into
each
graph
that
reflect
use
of
the
Low
and
High
COI
values
in
the
calculation
of
benefits.
Note
that
the
curves
only
shift
horizontally
relative
to
the
curves
derived
from
the
Enhanced
COI
(
that
is,
benefits
change,
but
costs

constant
in
this
sensitivity
analysis).
As
a
result,
the
conclusion
for
all
three
values
for
the
COI
is
the
same
as
for
the
Enhanced
COI:
all
alternatives
are
cost­
effective.
No
regulatory
alternative
provides
more
benefits
at
the
same
or
lower
cost
than
another,
and
no
alternative
can
achieve
lower
costs
for
the
same
or
greater
level
of
benefits
than
another.

Cost
Per
Illness
Avoided
and
Cost
Per
Death
Avoided
Exhibit
P.
8
presents
the
COI
avoided
using
three
values
for
COI.
These
are
in
2000$,
are
unadjusted
for
future
real
income
growth,
and
are
not
weighted
by
when
in
time
the
illnesses
are
avoided.
In
Chapter
8,
the
Enhanced
COI
was
compared
against
the
values
in
Exhibit
8.18,
which
are
the
costs
that
each
regulatory
alternative
imposes
to
avoid
each
illness.
Similarly,
we
can
compare
the
values
in
Exhibit
8.18
to
the
Low
and
High
COI
values.

In
summary,
the
results
when
using
the
Low
COI
are
exactly
the
same
as
when
using
the
Enhanced
COI:
all
alternatives
pass
this
test,
except
when
estimates
for
Alternative
A1
are
derived
from
distributions
based
on
the
ICRSSL
data
set.
Comparing
the
values
in
Exhibit
8.17
against
the
High
COI
value
of
$
1,071.81
shows
that
in
only
one
case,
A1
based
on
the
ICRSSL
distribution
at
a
3­
percent
discount
rate,
does
the
cost
of
avoiding
an
illness
exceed
the
High
COI
value.
Remember
that
this
test
is
very
conservative
and
counts
both
the
illnesses
and
deaths
avoided.

Summary
of
Sensitivity
Analysis
The
Preferred
Alternative
passes
threshold
economic
criteria
whether
using
the
Low,
Enhanced,
or
High
Estimate
for
COI.

°
The
Preferred
Alternative
(
A3)
has
positive
net
benefits
(
Exhibit
P.
10).
(
In
fact,
this
is
also
true
for
Alternatives
A2
and
A4,
and
true
for
Alternative
A1
under
11
of
the
12
possible
combinations
of
COI,
data
set,
and
discount
rate.)
Again,
this
conclusion
is
especially
strong
because
the
quantified
benefit
estimates
are
underestimated
since
they
do
not
include
the
value
of
the
unquantified
benefits.

°
The
Preferred
Alternative
(
A3)
is
cost­
effective:
no
other
alternative
achieves
greater
net
benefits
at
the
same
cost
or
the
same
benefits
(
this
is
true
for
all
the
alternatives)
(
Exhibit
P.
4).

°
The
Preferred
Alternative
(
A3)
is
cost­
effective
based
on
comparing
the
cost
of
the
rule
to
either
the
number
of
illnesses
or
deaths
avoided
(
and
this
is
still
true
for
Alternatives
2
and
4).

The
Preferred
Alternative
is
the
superior
alternative
across
a
wide
variety
of
measures,
including
when
considering
alternative
values
for
the
COI.

°
Under
most
conditions
(
in
7
of
12
combinations),
the
Preferred
Alternative
shows
the
highest
net
benefits
at
the
mean
(
Exhibit
P.
6).

°
The
Preferred
Alternative,
and
perhaps
Alternative
A2,
appear
to
be
especially
good
bargains.
The
other
alternatives
have
either
significantly
fewer
benefits
for
similar
costs
or
greater
benefits,
but
at
dramatically
higher
costs
(
Exhibit
P.
4).

°
In
the
analysis
of
incremental
benefits,
the
Preferred
Alternative
bounds
the
optimal
level
of
zero
incremental
net
benefits
(
Exhibit
P.
11),
in
all
six
of
the
Low
COI
conditions
and
in
three
of
the
six
High
COI
conditions.
No
other
alternative
has
better
performance
across
both
the
Low
and
High
COI
estimates.

The
Preferred
Alternative
is
the
superior
alternative
when
benefits
are
near
the
average
values
estimated,
at
levels
near
the
benefits
based
on
the
Low
COI,
and
at
levels
nearly
as
high
as
the
High
COI.

°
The
net
benefits
of
the
Preferred
Alternative
are
most
often
highest
near
the
mean
value
of
benefits
and
over
much
of
the
range
reflecting
uncertainty
in
benefits
estimates
(
Exhibits
P.
12
and
P.
13).
Near
the
benefits
levels
corresponding
to
the
Low
COI,
Alternative
A4
under
some
conditions
nears
a
break
point
relative
to
A3.
Up
to
levels
nearly
as
high
as
those
corresponding
to
the
High
COI,
A3
remains
the
highest
ranked
alternative.

This
sensitivity
analysis
shows
that
the
selection
of
the
Preferred
Alternative
appears
justified,
even
when
alternative
values
for
the
COI
are
considered.

Appendix
Q
presents
total

The
methodology
for
estimating
these
costs
is
provided
in
Chapter
6.
The
costs
given
are
the
undiscounted
costs
at
full

are
both
given.
For
each
set
of
costs
the
mean,
median,
5th

and
95th

costs
are
given.

To
estimate
treatment

a
number
of
conditions
were
used
(

Introduction
and
Summary
A
key
input
to
the
Long­
Term
2
Enhanced
Surface
Water
Treatment
Rule
(
LT2ESWTR)
risk
assessment
model
is
the
rate
of
mortality
associated
with
cryptosporidiosis.
This
is
discussed
in
section
5.2.3
(
Dose
Response
Assessment).
The
mortality
rate
as
used
in
this
analysis
is,
given
a
case
of
cryptosporidiosis,
the
probability
of
a
fatality
from
that
illness.
As
discussed
in
section
5.2.3,
the
risk
assessment
model
uses
different
mortality
rates
for
those
with
AIDS
and
the
general
populations.

Cryptosporidiosis
is
considered
nonfatal
in
healthy
adults,
so
the
mortality
rate
in
the
general,
non­
AIDS,
population
represents
deaths
for
those
with
other
conditions
or
diseases
that
hinder
recovery
from
cryptosporidiosis.
The
mortality
rate
used
for
the
general
population
is
the
mortality
rate
associated
with
the
1993
Milwaukee
Cryptosporidium
outbreak
for
those
without
AIDS.
This
rate
is
used
as
an
estimate
of
the
mortality
rate
for
future
cryptosporidiosis
cases
because
no
significant
treatments
that
would
likely
lessen
mortality
have
been
developed
since
then.

Data
from
the
1993
Milwaukee
cryptosporidiosis
outbreak
are
also
used
to
develop
the
mortality
rate
for
people
with
AIDS.
However,
for
those
with
AIDS,
new
treatments
have
become
available
since
the
Milwaukee
outbreak
that
greatly
prolong
life.
As
a
result
of
the
advent
of
highly
active
anti­
retroviral
therapy
(
HAART)
in
1995,
the
rate
of
death
for
those
with
AIDS
from
all
causes
has
declined
dramatically.
The
Dose­
Response
Assessment
includes
a
factor
to
reflect
the
apparent
lessened
mortality
among
persons
with
AIDS.
Data
from
the
Centers
for
Disease
Control
and
Prevention
(
CDC)
for
1993
and
19991
suggest
that,
among
those
with
AIDS,
the
death
rate
for
all
reasons
in
1999
was
only
12.3
percent
of
the
rate
in
1993,
the
year
of
the
Milwaukee
outbreak.
To
reflect
the
probable
improved
ability
of
those
with
AIDS
to
survive
cryptosporidiosis,
the
mortality
rate
for
those
with
AIDS
during
the
Milwaukee
outbreak
was
adjusted
by
this
factor
and
applied
to
each
year
of
the
25­
year
analysis
without
change
(
that
is,
without
allowing
for
further
changes
in
mortality
rates).
This
no­
trend
approach
is
considered
a
reasonable
best
estimate,
given
the
difficulty
of
predicting
future
trends
in
AIDS­
related
mortality,
including
the
lack
of
cryptosporidiosis­
specific
information.

This
appendix
presents
the
latest
AIDS­
related
mortality
data
available
from
the
CDC,
summarizes
the
history
of
AIDS­
related
mortality,
provides
information
regarding
the
factors
that
may
affect
future
AIDS­
related
mortality,
and
discusses
the
potential
impact
on
the
LT2ESWTR
benefits
analysis
results
of
using
the
latest
estimates
from
CDC
and
other
mortality
rates
(
arbitrarily
bounded)
to
Economic
Analysis
for
the
LT2ESWTR
Proposal
R­
2
June
2003
reflect
at
least
some
of
the
range
of
possible
values
that
may
develop
in
future
years.
This
appendix
does
not
discuss
other
related
assumptions,
such
as
the
constant
ratio
of
persons
living
with
AIDS
to
the
general
population
used
in
the
model
and
the
mortality
rates
for
the
general
population.

The
impact
of
using
the
latest
data
from
CDC
is
that
using
CDC's
revised
data
for
1999
would
raise
the
mortality
rate
for
those
with
AIDS
by
half
(
a
50
percent
increase),
and
raise
the
total
estimate
of
mean
benefits
by
about
a
fifth
(
20
percent).
Using
the
CDC's
estimate
for
2000
would
reduce
the
AIDSrelated
mortality
rate
by
14
percent,
and
the
overall
level
of
mean
benefits
by
8
percent.
Although
CDC
has
tried
to
adjust
this
initial
2000
estimate
for
potential
delays
in
reporting,
the
estimate
is
likely
to
be
revised
in
subsequent
years,
and
may
well
be
higher
than
this
initial
estimate
(
for
example,
data
for
1999
increased
by
50
percent).
Using
either
of
these
new
estimates
from
CDC
would
not
have
changed
the
conclusions
of
the
EA
or
the
selection
of
the
Preferred
Alternative.

The
review
of
the
confounding
factors
that
influence
the
future
mortality
of
those
with
AIDS
gave
no
definite
direction
of
future
change
(
that
the
rate
will
definitely
increase
or
definitely
decrease).
The
bounding
analysis,
presented
below,
assessed
the
impact
on
LT2ESWTR
benefits
due
to
the
AIDSrelated
mortality
rate
either
increasing
or
decreasing.
This
analysis
was
done
by
arbitrarily
doubling
and
halving
the
1999
rate
used
in
the
economic
analysis
(
EA)
and,
as
in
the
EA
analysis,
assuming
a
constant
mortality
rate
over
the
period
of
the
analysis.

The
results
of
the
bounding
analysis
indicate
that
doubling
the
AIDS­
related
mortality
rate
would
result
in
mean
total
benefits
41
percent
higher,
and
no
change
in
the
conclusion
of
the
EA
or
selection
of
the
Preferred
Alternative.
The
result
of
halving
the
AIDS­
related
mortality
rate
would
be
a
mean
total
benefits
estimate
24
percent
lower
than
used
in
the
EA.
This
reduction,
if
considered
alone,
would
significantly
improve
the
relative
standing
of
Alternative
A4,
making
it
essentially
equal
to
the
Preferred
Alternative.
However,
accounting
for
unquantified
benefits,
which
are
described
in
section
5.4,
would
favor
the
Preferred
Alternative.
In
summary,
given
the
likelihood
that
increases
in
the
AIDS
mortality
rate
are
at
least
as
likely
as
decreases,
and
that
unquantified
benefits
exist,
the
conclusions
of
the
EA
and
the
selection
of
the
Preferred
Alternative
are
not
challenged.

Adjustment
Factor
The
adjustment
factor
for
AIDS­
related
mortality
used
in
the
Dose
Response
Assessment
is
computed
from
both
death
and
population
data.
The
EA
uses
1999
data
on
the
number
of
AIDS
deaths
as
cited
in
CDC's
1999
end­
of­
year
HIV/
AIDS
Surveillance
Report.
CDC
has
revised
the
1999
estimate
upward
by
50
percent
in
the
2000
end­
of­
year
report
(
the
latest
available).
This
latter
report
also
provides
initial
data
for
2000,
which
are
slightly
lower
than
the
initial
(
1999)
values
used
in
this
EA
(
both
are
shown
in
Exhibit
R.
1).
The
initial
estimate
for
2000
is
based
on
actual
reported
data
and
is
adjusted
to
account
for
projected
delays
in
reporting.
The
CDC
released
revised
estimates
for
the
number
of
persons
living
with
AIDS
in
1999
in
a
supplement
to

In

for

was
not
reported
in
CDC's

However,
if
the
increase
in
deaths
were
subtracted
from
the

of
persons
living
with
AIDS,
a
revised
number
might
be
312,794
(
that
is,
317,652
­
4,802),
and
the
mortality

would
then
be
18.8
percent.

The
revised
estimate
for
the
AIDS
mortality
rate
in
1999
is
50
percent
higher
than
previously
reported,
and
the
newly

would
imply
a

10.6
percent
rather
than
the
12.3
percent
used
in
the
analysis.
(
The
impacts
of
these
differences
will
be
discussed
in

The
2000
estimate
will
likely
be

as

The

43
percent
drop
from
1999
(
revised)
(
18.5

to
2000
(
10.6
percent)
may
be
less
indicative
of
the
historical
trend
than
the
differences
between
1999
and
1998,
which
are
based
on
more
complete

rather
than

History
of
AIDS­
Related
Mortality
Rates
Over
roughly
the
past
decade,
the
AIDS­
related
mortality
rate
has
been
declining.
This
decline
has
resulted
from
both
a
decrease
in
the
number
of
AIDS­
related
deaths
and
an
increase
in
the
number
of
people
living
with
AIDS.
However,
the
decline
in
AIDS­
related
deaths
has
slowed
somewhat
in
recent
years.

Decline
in
AIDS­
Related
Deaths
Due
to
Use
of
HAART
Data
show
that
AIDS­
related
deaths
declined
as
people
with
AIDS
began
using
HAART,
which
became
available
in
1995
and
appears
to
be
successful
in
significantly
prolonging
the
lives
of
persons
with
AIDS.
Since
the
introduction
of
HAART,
treatment
has
become
available
to
almost
all
people
in
the
United
States
with
known
cases
of
AIDS
(
Boyle
2002).
The
result,
at
least
in
the
short
term,
is
a
reduction
in
the
numbers
of
deaths
of
persons
with
AIDS
(
Exhibit
R.
2).
With
the
availability
of
the
treatment
now
nearly
universal
in
the
United
States,
the
reduction
in
the
number
of
deaths
is
slowing
after
the
steep
declines
seen
in
1996
and
the
first
half
of
1997.
This
observation
derives
from

The
initial
estimate
for
2000
appears
to
show
a
continued
slight
decline.
However,
in
previous
reports
from
the
CDC
(
HIV/
AIDS
Surveillance
Reports),
early
results
have
been
revised
upward
in
later
reports
as
additional
data
became
available.
Whether
the
number
of
deaths
has
continued
its
slight
decline
or
leveled
off
cannot
be
determined
reliably
from
the
available
data.

People
Living
With

In
addition
to
the
decline
in
AIDS­
related
deaths,
new
cases
of
AIDS
also
declined
because
of
HIV
treatments;
but
more
people
are
living
with
AIDS.

the

The
number
of
new

is
most
directly
affected
by
the
effectiveness
of
treatments,
including
HAART,
that
prevent

and
Karon
et
al.
(
2001)
described
it
as
"
relatively
constant."

The
population
of
persons
living
with
AIDS
has
continued
to
grow
as
new
cases
are
identified
and
fewer
people
die
from
the
disease
and
its
complications.
The
annual
increase
from
1998
to
2000
was
18
percent
and
the
total
number
of
persons
living
with
AIDS
is
estimated
at
322,865
in
2000
(
CDC,
2000).

Overall
Effect
on
AIDS
Mortality
Rates
Data
show
that
the
overall
AIDS
mortality
rate
continues
to
decline,
but
that
the
decline
is
slowing
(
Exhibit
R.
3).
The
mortality
rates
used
in
the
EA
benefits
model
are
computed
from
both
death
and
population
data.
Because
the
underlying
data
on
deaths
have
been
revised
in
the
end­
of­
year
2000
Surveillance
Report,
the
mortality
rates
based
on
these
data
are
also
shown.
However,
because
the
2000
estimate
will
likely
be
revised
in
subsequent
years,
the
apparent
43
percent
drop
in
AIDS
mortality
from
1999
(
revised)
to
2000
may
be
less
indicative
of
the
historical
trend
than
the
differences
between
1999
and
1998.

4
Factors
Affecting
Mortality
in
the
Future
Statistical
Shift
Over
Time
Several
factors
affect
the
mortality
rate
of
persons
with
AIDS.
One
(
identified
earlier)
is
that
life­
prolonging
treatments
are
widely
available
and
used.
However,
the
rapid
decline
in
mortality
rates
that
accompanied
their
introduction
may
be
temporary.
HAART
is
not
considered
a
cure
for
AIDS.
If
the
only
effect
is
increased
longevity,
but
with
a
similar
pattern
of
eventual
disease,
those
who
are
now
less
susceptible
would
become
susceptible
again
in
the
future.
In
such
a
case,
the
mortality
rate
could
conceivably
climb
to
near
historical
levels.
The
reason
it
would
be
unlikely
to
fully
reach
historical
levels
is
that
the
longer
the
increased
longevity,
the
more
likely
it
is
that
deaths
would
occur
for
reasons
other
than
AIDS.
This
reasoning
suggests
that,
with
all
other
influences
equal
(
which
they
are
not),
the
mortality
rate
would
lessen
for
a
period
roughly
corresponding
to
increased
longevity,
then
increase
to
some
new
level.
Many
other
factors
are
also
important,
however.

Drug
Resistance
History
supports
a
view
that
infectious
disease
mortality
initially
drops
considerably
upon
the
introduction
of
successful
treatment,
but
after
a
lag
the
mortality
rate
stabilizes
or
slightly
increases
as
drug
resistance
and
other
factors
counteract
the
benefit
of
treatment.
The
treatment
of
tuberculosis
(
TB)
after
World
War
II
with
streptomycin
had
immediate
success,
but
within
a
few
months
drug
resistance
began
to
show.
Physicians
were
able
to
develop
additional
antibiotics,
and
TB
was
treated
using
a
multiple
drug
regimen
(
NJMS
1996).
The
mortality
rate
for
tuberculosis
in
industrialized
countries
had
been
declining
slowly
until
the
mid­
1980s,
when
the
mortality
rate
stabilized
and
more
recently
has
increased
slightly
(
NJMS
1996).
Some
similar
patterns
are
beginning
to
be
identified
with
AIDS.

Drug
resistance
to
AIDS
therapies
is,
in
fact,
increasing.
If
a
patient
develops
a
drug­
resistant
strain
of
HIV,
treatment
becomes
difficult.
If
new
regimens
cannot
be
developed
for
this
individual,
the
disease
will
proceed
as
it
did
prior
to
treatment,
and
result
in
AIDS­
related
death.
Forty­
nine
percent
of
individuals
with
HIV
have
drug­
resistant
strains
(
Brown
2001).
Among
those
HIV
individuals
who
have
not
started
treatment,
20
percent
have
a
strain
resistant
to
at
least
one
drug,
an
increase
from
3
to
5
percent
of
new
cases
several
years
ago
(
Brown
2001).
Because
the
therapies
for
HIV
and
AIDS
are
essentially
the
same,
this
suggests
that
those
who
progress
from
HIV
to
AIDS
are
increasingly
likely
to
have
drug­
resistant
strains.
As
the
proportion
of
persons
with
drug­
resistant
strains
increases
within
the
population
of
those
living
with
AIDS,
this
would
be
an
upward
influence
on
the
AIDS
mortality
rate.

Side
Effects
Leading
to
Cessation
of
Treatment
Another
factor
that
may
affect
mortality
is
the
cessation
of
therapy
due
to
intolerable
side
effects.
Over
time,
the
side
effects
from
drug
therapy
(
such
as
diarrhea,
peripheral
neuropathy,
severe
rash,
jaundice,
pancreatitis,
kidney
stones,
and
others)
become
too
painful
or
uncomfortable
for
many
people
to
bear
(
Highleyman
2000,
NYSDHAI
2002,
Griffiths
2002).
The
number
of
patients
that
will
drop
treatment
in
the
coming
years
due
to
side
effects
is
therefore
likely
to
increase
(
NYSDHAI
2002).
Studies
show
that
relapse
is
rapid
after
cessation
of
therapy;
among
those
tested
who
had
no
detectable
virus
in
their
system,
the
time
to
relapse
to
pre­
treatment
levels
of
virus
in
the
blood
ranged
from
4
to
31
days,
with
most
relapsing
within
2
to
3
weeks
after
ceasing
therapy
(
Marble
2000,
Medscape
2002).
Even
for
those
patients
who
had
been
treated
for
over
2
years,
relapse
occurred
promptly
after
cessation
of
therapy
(
Medscape
2002).
If
a
treatment
regimen
cannot
be
developed
that
reduces
side
effects
to
Economic
Analysis
for
the
LT2ESWTR
Proposal
R­
7

tolerable
levels,
some
patients
will
likely
quit
treatment,
and
their
mortality
rate
from
various
sources,
including
cryptosporidiosis,
would
increase.
Over
time,
as
more
people
with
AIDS
develop
these
intolerable
side
effects
and
cease
treatment,
the
overall
AIDS
mortality
rate
would
also
increase.

Mortality
from
Side
Effects
The
previous
factors
that
may
affect
mortality
would
increase
the
mortality
rate,
and
are
assumed
to
have
a
parallel
effect
on
deaths
from
cryptosporidiosis
in
persons
with
AIDS.
There
is
one
factor,
however,
that
may
increase
mortality
among
persons
with
AIDS,
but
not
the
mortality
from
cryptosporidiosis.
Among
the
side
effects
of
HAART
are
fat
redistribution,
elevated
triglycerides,
and
potential
insulin
resistance
(
Louie
et
al.
2002,
Highleyman
2000).
These
side
effects
may
increase
cardiovascular
morbidity,
and
thus
the
mortality
rate
among
AIDS
patients
may
rise
in
the
future
even
with
successful
therapy.
However,
mortality
from
non­
AIDS
or
immunological
difficulties
would
not
be
considered
relevant
to
a
mortality
rate
due
to
infection
by
Cryptosporidium.

New
Therapies
New
therapies
for
persons
with
AIDS
may
be
developed
sometime
before
2028
(
the
extent
of
the
period
of
analysis
in
this
EA).
Therapies
that
extend
life
would
create
a
new
statistical
time
shift,
as
described
at
the
beginning
of
R.
4.
These
therapies
could
be
more
effective
than
current
ones
against
drug­
resistant
strains,
could
be
more
easily
tolerated,
or
could
provide
benefits
longer
than
current
therapies.
Extensive
research
is
being
conducted
on
HIV
vaccines
and
therapies,
which
include
integrase
inhibitors,
fusion
inhibitors,
gene
therapies,
and
pseudovirion
and
other
vaccines.
The
likelihood
of
new
therapies
being
developed
and
the
possible
time
line
for
their
use
is
difficult
to
foresee.

R.

Sensitivity
Analysis
This
section
presents
the
impact
of
using
alternative
estimates
for
the
AIDS
mortality
adjustment
factor.
This
is
done
in
two
ways.
The
first
way
is
to
discuss
the
differences
of
using
the
newer
estimates
now
available
from
the
CDC.
The
second
is
a
more
generic
sensitivity
analysis
that
will
examine
the
impact
on
the
benefits
estimates
of
using
factors
above
and
below
the
estimates
used
in
the
EA
analysis.
The
changes
in
AIDS
mortality
rates
do
not
produce
a
one­
to­
one
change
in
estimates
in
benefits
because
other
factors
(
such
as
the
populations
served
by
filtered
and
unfiltered
systems,
the
mortality
rate
for
the
general
population,
income
growth
and
income
elasticity,
and
the
cost
of
illness)
also
contribute
to
the
estimate
of
benefits.

These

not
significant
enough
to
reverse
the
general
conclusion
of
benefits
exceeding
costs.
Benefits
so
greatly
exceed
costs
 
by
factors
of
3
to
13
fold
(
Exhibits

and
8.6b)
 
that
benefit
estimates
8
percent
lower
(
the
mean
percent
change

data)
would
not
alter
that
conclusion.

These
differences
also
do
not
significantly
change
the
relative
rankings
of
the
alternatives,
or
the
choice
of
the
Preferred
Alternative.
Appendix
P
addressed
this
question
by
looking
at
alternative
values
for
the
cost
of
illness.
Comparing
the
results
of
Exhibit
R.
4
to
those
in
Exhibits
P.
14
and
P.
15
is
helpful.
Exhibits
P.
14
and
P.
15
display
the
effect
of
using
a
benefit
estimate
that
is
22
percent
higher
and
an
estimate
that
is
18
percent
lower
than
used
in
the
EA.
Using
the
Revised
1999
estimate
would
result
in
a
19
percent
increase
in
the
mean
estimate
of
benefits,
comparable
to
the
22
percent
values
used
in
Exhibits
P.
14
and
P.
15.
Using
the
initial
2000
data
would
result
in
a
decrease
of
8
percent
(
at
the
mean),
about
a
half
of
the
decrease
shown
in
Exhibits
P.
14
and
P.
15.
One
conclusion
is
that
using
the
revised
1999
data
(
the
values
higher
than
in
the
EA),
the
Preferred
Alternative
is
and
remains
the
alternative
with
the
highest
net
benefits
in
three
of
the
four
conditions
of
discount
rates
and
underlying
data
sets,
and
becomes
the
alternative
with
the
highest
net
benefits
in
the
fourth.
Using
the
2000
data
for
AIDS
mortality,
the
Preferred
Alternative
is
and
remains
the
alternative
with
the
highest
net
benefits
in
three
of
the
four
conditions,
and
is
and
remains
a
close
second­
best
in
the
fourth
(
ICRSSL,
7
percent).
In
summary,
the
Preferred
Alternative
would
not
lose
its
relative
advantage
using
these
alternative
estimates
for
AIDSrelated
mortality.

5.2
Impacts
of
Using
Alternative
Estimates
for
AIDS­
Related
Mortality
The
discussion
in
section
R.
4
of
the
factors
that
may
affect
AIDS­
related
mortality
in
the
future
does
not
lead
to
a
single
conclusion.
It
suggests
that
there
exist
factors
that
could
easily
raise
the
mortality
rate
substantially
higher
than
the
rates
seen
in
1999
and
projected
for
2000,
but
new
treatment
breakthroughs
could
substantially
lower
the
rate
in
future
years.
Benefits
from
the
LT2ESWTR
are
projected
to
begin
in
2008
and
the
analysis
makes
projections
through
2028.
Considering
the
length
of
the
Economic
Analysis
for
the
LT2ESWTR
Proposal
R­
9
June
2003
period
of
analysis
and
the
lack
of
projections
available
regarding
mortality
rates,
this
section
uses
both
higher
and
lower
values
to
assess
the
possible
impact
of
alternative
AIDS
mortality
rates.

Whatever
does
happen
to
these
rates
in
the
future,
it
is
unlikely
that
they
will
remain
constant
from
1999
or
2000
through
2028.
For
the
purposes
of
this
analysis,
however,
two
stable
"
no­
trend"
values
are
used.
The
first
is
double
the
rate
used
in
the
EA;
the
second
is
half
of
that
used
in
the
EA.
These
differences
are
larger
than
those
considered
in
section
R.
5.1,
and
have
correspondingly
greater
impact
on
the
estimate
of
total
benefits

These

on
the
level
of

are,
however,
not
significant
enough
to
reverse
the
general
conclusion
of
benefits
exceeding

Benefits
so

by

that
benefit
estimates

percent
lower
(
the

the

value)
would
not
alter
that
conclusion.

Further,
these
larger
differences
do
not
significantly
change
the
relative
rankings
of
the
alternatives
or
the
choice
of
the

Alternative.
Again,
comparing
the
results
of

to
those

holds
steady

as

from

ICRSSL,
7
percent),
the
Preferred
Alternative
goes
from
being
a
close
second
(
to
Alternative
A4)
to
being
the
top­
ranked
alternative.
Thus,
at
such
an
increased
level
of
AIDS­
related
mortality
(
and
therefore
benefits
from
avoided
deaths),
the
choice
of
the
Preferred
Alternative
remains
reasonable
considering
the
range
of
possible
conditions.

In
considering
the
low
value
for
AIDS­
related
mortality,
it
is
near
the
line
shown
for
Low
Costof
Illness
in
Exhibits
P.
14
and
P.
15
(
Low
COI
is
­
18
percent
compared
to
­
24
percent
here).
Using
this
lower
value
for
AIDS
mortality,
the
Preferred
Alternative
and
Alternative
A4
are
nearly
equal.
With
the
ICRSSL
data
set,
Alternative
A4
would
have
higher
net
benefits
(
with
the
Preferred
Alternative
a
close
second).
Using
the
ICR
data
set
(
7
percent),
Alternatives
A4
and
the
Preferred
Alternative
are
essentially
equal,
and
using
the
ICR
data
set
(
3
percent),
the
Preferred
Alternative
has
slightly
higher
net
benefits.
Using
such
a
lower
value
alone
for
AIDS­
related
mortality
could
challenge
the
selection
of
the
Preferred
Alternative.
However,
as
noted
earlier,
the
effect
of
this
lower
value
would
be
offset

somewhat
by
the
consideration
of
greater
unquantified
benefits
associated
with
the
Preferred
Alternative.
In
summary,
given
that
increases
in
the
AIDS
mortality
rate
are
deemed
as
likely
as
decreases,
the
conclusions
of
the
EA
and
the
selection
of
the
Preferred
Alternative
are
not
challenged.

In
conclusion,
the
projection
of
AIDS­
related
mortality
rate
is
uncertain.
If
the
factors
identified
as
exerting
an
upward
influence
on
the
AIDS­
related
mortality
rate
continue,
the
decline
observed
in
this
rate
over
the
past
several
years
will
soon
bottom
out,
and
AIDS­
related
mortality
will
begin
to
increase.
Less
certain
is
the
possibility
or
timing
of
new
therapies
that
could
lessen
the
threat
from
this
disease,
but
substantial
resources
are
devoted
to
this
outcome.
Mortality
rates
ranging
from
above
to
somewhat
below
current
estimates
support
the
selection
of
the
Preferred
Alternative.
Mortality
rates
that
are
substantially
lower
would
support
careful
consideration
of
other
alternatives
and
perhaps
more
careful
enumeration
of
other
benefits
not
now
quantified.

Appendix
S
Analysis
of
Individual
Risk
by
Initial
Bin
S.
1
Introduction
Under
each
regulatory
alternative,
systems
are
assigned
an
initial
"
bin"
based
on
source
water
monitoring.
This
appendix
groups
population
based
on
these
bins
and
analyzes
the
distribution
of
individual
risk
for
each
of
these
bins.
The
conclusions
are
presented
in
two
ways:

°
Tabular
information
on
the
percent
of
the
population
that
face
annual
risks
of
illness
within
selected
ranges
(
Exhibit
S.
1).
Additional
tables
show
the
data
in
several
different
forms
(
Exhibits
S.
2
through
S.
4).

°
Cumulative
distribution
graphs
that
show
the
distribution
of
individual
risk
based
on
Pre­
LT2ESWTR
conditions,
the
distribution
based
on
the
minimal
compliance
with
the
LT2ESWTR,
and
based
on
the
projected
actual
compliance
with
the
rule
(
Exhibits
S.
5
through
S.
12).
These
graphs
are
similar
to
Exhibit
5.12,
where
the
full
distributions
of
risks
are
presented.
The
graphs
in
this
appendix
give
additional
insight
as
to
the
distribution
of
risks
within
each
bin
before
and
after
the
rule.

The
remainder
of
the
appendix
includes
the
following
additional
documentation:

°
A
discussion
and
graph
of
the
relationship
among
Modeled
True,
Measured,
and
Binning
concentrations
of
Cryptosporidium
that
is
useful
for
understanding
the
derivation
of
the
tables
and
graphs
in
this
appendix.

°
A
discussion
of
the
steps
involved
in
computing
the
data
for
this
appendix,
with
accompanying
graphs
that
show
the
step­
by­
step
process
for
a
sample
data
set
and
regulatory
alternative.
This
and
the
previous
sections
also
serve
as
a
good
illustrations
of
how
rule
alternatives
reduce
risk.

Key
assumptions
in
the
analysis
are
the
following:

°
Only
community
water
systems
(
CWS)
that
filter
water
are
considered
in
this
analysis.

°
The
"
bins"
used
in
this
analysis
are
those
in
which
systems
are
initially
classified.
An
initial
bin
contains
all
those
systems
whose
source
water
places
them
in
a
bin.
This
includes
those
who
are
able
to
receive
credits
to
reflect
their
current
treatment
in
place
and,
therefore,
lower
requirements
for
additional
treatment.
For
example,
systems
in
the
1­
log
bin
have
to
install
treatment
of
0.0,
0.5,
or
1.0
log.
It
also
includes
systems
who
are
projected
to
install
treatment,
but
who
would
choose
treatments
that
achieve
greater
than
that
required
by
their
bin
requirement.

°
Variability
from
drinking
water
ingestion
is
not
included.

Exhibits
S.

show
the
percent
of
populations
facing
risk
levels
in
different
forms,
all
based
on
initial
bin
classifications
and
are
of
CWS
only.
Although
the
underlying
data
are
the
same,
they
are
presented
in
different
formats
to
help
easily
answer
question
of
different
forms.

°
Exhibit
S.
1
shows
the
percent
of
populations
facing
annual
individual
risk
within
exclusive
selected
ranges.
It
divides
the
total
population
into
five
levels
of
risk
and
shows
the
percent
of
the
population
within
each
level.
This
table
uses
global
percentages
and,
therefore,
data
add
both
across
and
up
to
totals.
This
table
is
useful
to
answer
questions
about
the
proportion
of
the
total
population,
such
as,
"
What
portion
of
the
population
in
"
no
action"
bins
are
estimated
to
have
risks
between
10­
3or
and
10­
4?"
and
"
What
percent
of
the
population
is
in
the
1.0
log
bin
for
alternative
A4?"

°
Exhibit
S.
2
shows
the
percent
of
the
total
population
facing
risks
at
and
above
four
levels
 
from
10­
5or
greater
to
10­
2
or
greater
annual
risk
of
illness.
These
are
cumulative
of
the
numbers
in
Exhibit
S.
1
and
are
still
in
the
form
of
global
percentages.
The
individual
cell
data
can
be
summed
up
to
column
totals,
but
columns
are
to
be
compared,
not
summed.
This
table
is
useful
to
answer
questions
that
focus
on
individual
risk
levels
that
might
be
of
interest,
and
to
identify
what
percent
of
the
population
face
risks
greater
than
that
level,
such
as,
"
What
portion
of
the
total
population
in
"
no
action"
bins
are
estimated
to
have
risks
above
10­
3?"

°
Exhibit
S.

uses
the
data
in
Exhibit
S.
2,
but
expresses
individual
cell
data
as
a
percentage
of
the
total
in
its
column.
These
local
percentages
add
vertically.
This
table
is
useful
to
answer
questions
about
the
percent
composition
of
alternatives
,
such
as,
"
What
portion
of
the
population
under
alternative
A3
facing
risks
of
10­
3
or
greater
are
in
the
`
no
action'
bin?"
(
For
example,
Exhibit
S.
2
tells
us
that
2.04
percent
of
the
total
population
are
in
this
group,
and
Exhibit
S.
2
tells
us
that
they
represent
71.84
percent
of
all
those
facing
risks
of
10­
3
or
greater.)

°
Exhibit
S.
4
shows
the
percentage
of
the
population
within
a
bin
that
exceed
a
specified
risk
level.
The
data
derive
from
Exhibit
S.
2
(
the
percent
of
all
those
who
are
in
that
bin
exceeding
a
risk
level)
divided
by
the
percentage
of
the
total
population
in
that
bin
(
the
first
three
columns).
The
first
three
columns
add
to
100
percent,
but
the
other
data
are
to
be
read
individually
and
do
not
sum
in
any
direction.
This
table
is
useful
to
answer
questions
such
as,
"
What
portion
of
the
population
in
"
no
action"
bins
are
estimated
to
have
annual
individual
risks
above
10­
3?"

Graphs
of
the
Cumulative
Distribution
of
Annual
Individual
Risk
by
Bin
The
graphs
of
the
distributions
of
individual
risk
for
people
served
by
all
filtered
systems
are
shown
in
the
Economic
Analysis
in
Exhibit
5.12.
The
graphs
below
are
analogous,
but
only
include
CWS
systems.
The
axes
have
been
switched
so
that
the
cumulative
percent
is
shown
on
the
X
axis
and
the
variability
from
drinking
water
ingestion
has
been
removed.
There
are
separate
charts
for
each
rule
alternative
and
each
of
two
data
sets,
the
ICR
and
ICRSSL
(
twelve
graphs
in
all,
Exhibits
S.
5
through
S.
16).
On
each
graph,
vertical
dashed
lines
separate
the
initial
bins.
Within
each
bin,
the
following
three
distributions
are
shown:

 
the
distribution
of
risk
based
on
finished
water
occurrence,
Pre­
LT2
(
after
considering
treatment
in
place
and
the
effects
of
credits)

 
the
distribution
of
risk
based
on
the
treatment
required
by
that
rule
alternative
and
that
bin
(
again
taking
into
account
the
credits
earned
by
some
systems)

 
the
distribution
of
risk
actually
achieved,
reflecting
that
many
systems
are
expected
to
achieve
more
treatment
than
the
minimum
required
Note
that
within
a
bin,
each
distribution
is
sorted
independently,
and
therefore,
a
particular
system
may
appear
at
different
points
in
each
of
the
distributions.
Also
note
that
the
distributions
based
on
finished
water
occurrence
overlap,
that
is,
some
individuals
in
a
lower
bin
have
a
higher
risk
than
some
in
higher
bins.
This
is
due
to
misclassification
of
systems
during
the
sampling
process
and
to
the
differences
in
treatment
in
place
between
systems.

The
differences
between
the
alternatives
can
be
seen
at
particular
risk
levels.
For
example,
from
Exhibit
S.
2,
we
see
that
at
a
risk
of
1x10­
4
risk
level
(
that
is,
a
1
in
1,000
chance
of
becoming
ill
in
a
year),
Alternative
A3
leaves
25.02
percent
of
the
total
population
at
or
above
this
risk
overall
(
ICR
data).
Exhibit
S.
2
also
shows
that
of
those
25.02
percent
exposed
to
the
1x10­
4
risk
level,
18.69
percent
are
in
the
No
Action
bin
and
5.59
percent
are
in
the
1
log
bin.
Exhibit
S.
7
shows
the
distribution
of
that
25.02,
18.69,
and
5.59
percent.
It
is
the
portion
of
the
distributions
above
the
10­­
4
line.
Interestingly,
there
are
not
significantly
higher
spikes
in
higher
bins
because
of
the
additional
treatment
used
under
Alternative
A3.
(
Note
that
adding
in
the
variability
from
drinking
water
ingestion
would
slightly
heighten
any
spikes,
reflecting
those
that
drink
more
than
the
average
amount
of
water.)

For
another
example,
Exhibit
S.
8
and
Exhibit
S.
2
show
that
for
Alternative
A4,
40.9
percent
of
the
population
is
over
a
1x10­
4
risk
level
and
is
mostly
in
the
No
Action
(
22
percent
of
the
population)
and
0.5
log
bins
(
16
percent).
Over
16
percent
of
the
population
faces
risks
of
1x10­
4
or
greater
and
is
in
the
0.5
log
bin.
A
significant
spike
also
exists
in
the
1
log
bin.
At
the
higher
level
of
1x10­
2
risk
level
(
that
is,
a
1
in
100
annual
chance
of
becoming
ill),
Alternative
A3
has
almost
no
population
above
this
level,
but
Alternative
A4
has
about
0.6
percent
facing
these
risks.

Using
the
ICRSSL
rather
than
the
ICR
data
set,
the
percentages
of
population
above
a
selected
risk
level
is
generally
higher
at
individual
risk
levels
of
1x10­
4
and
1x10­
3
(
probably
because
fewer
systems
provide
additional
treatment)
and
about
the
same
at
1x10­
2.
Only
at
very
high
risk
levels
(
such
as
1x10­
1)
do
fewer
people
face
these
risks
(
probably
because
of
the
lower
estimated
occurrence)
than
estimated
under
the
ICR
data
set.

Relationship
Among
the
Modeled
True,
Measured,
and
Binning
Concentrations
of
Cryptosporidium
The
data
throughout
this
Economic
Analysis
uses
data
on
the
concentration
of
Cryptosporidium,
but
in
three
different
ways.
Exhibit
S.
17
shows
those
differences
graphically
using
the
ICR
data
set
and
alternative
A3.
Data
from
one
of
three
occurrence
data
sets
ICR,
ICRSSL,
or
ICRSSM)
are
used
by
a
model
to
model
a
"
true"
distribution.
This
distribution
of
occurrence
means
would,
when
measured
under
the
analytical
laboratory
protocols
produced
a
distribution
of
means,
labeled
as
"
measured
concentrations"
in
Exhibit
S.
17.
Binning
assignments
are
made
using
a
particular
computation
from
these
concentrations
 
the
highest
annual
running
average
from
2
years
of
monthly
data.
That
computation
actually
produces
the
step
function
shown
in
Exhibit
S.
17
as
MaxRAA.

Part
of
the
point
of
this
distinction
is
that
the
model
and
the
results
in
this
appendix
derive
their
estimates
of
risk
using
the
"
true
concentration"
estimated
distributions,
after
taking
into
account
any
treatment
in
a
system
required
by
being
binned
by
the
MaxRAA.

Development
of
Estimates
of
Risk
Distributions
by
Regulatory
Alternative
Bin
Developing
estimates
of
risk
distributions
by
regulatory
alternative
bin
requires
several
steps.
The
following
series
of
graphs
(
Exhibits
S.
18
through
S.
24,
and
S.
6)
illustrate
each
of
those
steps,
and
they
are
described
below.
These
graphs
are
for
filtered
CWS
systems
only.
These
graphs
do
not
include
the
variability
related
to
ingestion,
and
therefore
are
not
exactly
comparable
to
the
graphs
used
in
the
Economic
Analysis
(
Exhibits
5.12
and
C.
11).
Those
graphs
show
somewhat
steeper
peaks
due
to
accounting
for
the
above
average
ingestion
levels
by
some
individuals.
The
sequence
of
eight
graphs
is
repeated
for
each
regulatory
alternative.

1.
Modeled
Cryptosporidium
Source
Water
Distribution
by
Bin
In
this
step,
the
graph
(
Exhibit
S.
18)
shows
the
overall
source
water
occurrence
distribution
(
the
dashed
line)
of
system
means.
It
also
shows
how
that
distribution
divides
up
into
distributions
by
bin.
Note
that
the
distributions
for
each
bin
are
not
merely
cut
segments
of
the
overall
distribution,
but
overlap
somewhat,
reflecting
the
misclassification
inherent
in
the
monitoring,
testing,
and
Maximum
Running
Annual
Average
(
Max
RAA)
calculation
that
place
systems
into
bins.

2.
Pre­
LT2
Finished
Water
By
Bin,
Modeled
Points
In
this
step,
the
graph
(
Exhibit
S.
19)
repeats
the
distributions
of
source
water
by
bin,
and
adds
the
pre­
LT2
finished
water
concentration
for
each
of
the
simulation
points.
The
mass
of
data
points
reflects
the
percentages
of
small
and
large
systems,
the
modeled
treatment
effectiveness
based
on
the
appropriate
treatment
distribution
(
including
variability),
and
the
effect
of
treatment
credits.
Each
estimated
data
point
only
corresponds
vertically
to
its
original
placement
in
the
overall
distribution
curve
by
bin
(
the
lines
above).

3.
Pre­
LT2
Finished
Water
by
Bin,
Distribution
Curve
This
graph
(
Exhibit
S.
20)
resorts
all
the
individual
simulation
estimates
from
the
bottom
of
the
graph
for
Step
2
(
Exhibit
S.
19)
into
a
single
distribution
curve
for
each
bin.
(
The
points
on
the
finished
water
curve
now
do
not
correspond
vertically
to
the
source
water
curve
because
they
have
been
resorted
in
order
of
concentration.)

4.
Post­
LT2
Finished
Water,
Required
Reduction,
Modeled
Points
This
graph
(
Exhibit
S.
21)
repeats
the
finished
water
distributions
derived
in
Exhibit
S.
16,
and
adds
for
each
of
those
simulated
points,
the
Post­
LT2
required
log
reduction.
Thus,
in
the
No
Action
bins,
all
points
are
exactly
along
the
finished
water
curve.
For
an
action
bin,
there
may
be
several
lines,
reflecting
that
some
systems
must
meet
the
stated
bin
requirement
(
such
as
1
log),
but
others
may
be
entitled
to
a
half
log
or
1
log
credit.
In
some
cases,
that
may
mean
some
systems
in
action
bins
will
require
no
additional
treatment
and
lie
along
the
original
finished
water
distribution
line.

5.
Post­
LT2
Finished
Water,
Required
Reduction,
Distribution
Curve
This
graph
(
Exhibit
S.
22)
takes
the
individual
points
shown
in
the
graph
for
Step
4
(
Exhibit
S.
21)
and
resorts
them
into
distributions.
It
shows
two
distributions
by
bin:
the
distribution
of
Pre­
LT2
finished
water
and
the
minimum
improvement
required
by
that
rule
alternative.

Post­
LT2
Finished
Water,
Achieved
Reduction,
Modeled
Points
This
graph
(
Exhibit
S.
23)
again
shows
the
Pre­
LT2
finished
water
distribution
derived
in
Exhibit
S.
20
and
shown
in
Exhibits
S.
21
and
S.
22.
Analogous
with
Exhibit
S.
21,
this
graph
shows
the
simulation
points
based
on
the
achieved
log
reductions.
Because
the
Decision
Tree
includes
many
technologies
that
achieve
different
log
reductions,
there
can
be
multiple
lines.
For
example,
for
"
systems"
in
a
1
log
bin,
they
may
achieve
0.0
log
reduction
(
because
they
are
entitled
to
a
1
log
credit
and
need
no
further
treatment),
a
half­
log
reduction
(
because
they
are
entitled
to
a
0.5
log
credit
and
choose
a
technology
that
achieves
only
a
half
log
of
treatment),
or
any
degree
of
treatment
up
to
3.0
logs.

7.
All
Finished
Water
Distributions
by
Bin
This
graph
(
Exhibit
S.
24)
includes
the
distributions
from
the
graph
from
Step
5
(
finished
water
and
"
required",
Exhibit
S.
22),
and
adds
the
resorted
distribution
of
"
as
achieved"
from
the
graph
for
Step
6
(
Exhibit
S.
23).
In
this
one
graph,
each
bin
shows
the
finished
water
occurrence,
the
required
improvement,
and
the
improvement
achieved.

8.
Annual
Individual
Risk
by
Bin
Exhibit
S.
6
takes
the
distributions
from
the
graph
for
Step
7
and
computes
the
distributions
in
terms
of
annual
individual
risk
of
illness.
As
expected,
the
same
general
shapes
of
the
curves
from
Exhibit
S.
24
are
seen.
Again,
these
graphs
do
not
include
the
variability
related
to

therefore
are
not
exactly
comparable
to
the

used
in

Those

show
somewhat
steeper

accounting

the
above
average

levels
by
some
individuals.

On
an

level,
baseline
data
on

is
combined
with
unit

data
for
each
technology.
These
data
are
then
combined
with
compliance
forecasts
as
inputs
to
the
cost
models
which
calculate
total

These
costs
are
then
discounted
over
time
and
then
manipulated
to
give
total

as
well
as

Summary
EPA
is
required
by
the
Regulatory
Flexibility
Act
(
RFA),
as
amended
by
the
Small
Business
Regulatory
Enforcement
Fairness
Act
(
SBREFA)
(
5
USC
601
et
seq.),
to
prepare
a
Regulatory
Flexibility
Analysis
for
any
rule
subject
to
notice
and
comment
rulemaking
requirements
under
the
Administrative
Procedure
Act
or
other
statutes,
unless
the
Agency
certifies
that
the
rule
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities
(
5
USC
603(
a)).

This
appendix
describes
EPA's
initial
assessment
of
the
impacts
on
small
entities
as
a
result
of
the
LT2ESWTR.
Based
on
the
results
of
this
screening
analysis,
EPA
certifies
that
the
LT2ESWTR
will
not
have
a
significant
impact
on
a
substantial
number
of
small
entities.
Therefore,
in
accordance
with
5
USC
605,
EPA
did
not
prepare
a
formal
Initial
Regulatory
Flexibility
Analysis
(
IRFA)
or
a
Final
Regulatory
Flexibility
Analysis
(
FRFA).

W.

Methodology
The
screening
analysis
involves
four
major
tasks:
(
1)
defining
"
small
entities"
for
the
rule
being
analyzed,
including
PWSs
run
by
"
small
businesses,"
"
small
governments,"
and
"
small
organizations;"
(
2)
determining
what
number
constitutes
a
"
substantial
number"
of
these
entities;
(
3)
determining
how
"
significant
impacts"
will
be
measured;
and
(
4)
completing
a
screening
analysis.
If
the
screening
analysis
determines
that
a
substantial
number
of
small
entities
may
face
significant
impacts
as
a
result
of
the
rule,
then
a
formal
IRFA
and
FRFA
may
be
required.

W.
2.1
Defining
"
Small
Entities"
Affected
by
the
Rule
The
RFA
defines
small
entities
as
including
"
small
businesses,"
"
small
governments,"
and
"
small
organizations"
(
5
USC
601).
The
RFA
references
the
definition
of
"
small
business"
found
in
the
Small
Business
Act,
which
authorizes
the
Small
Business
Administration
(
SBA)
to
further
define
"
small
business"
by
regulation.
The
SBA
defines
small
businesses
by
category
using
the
North
American
Industry
Classification
System
(
NAICS).
For
example,
in
the
manufacturing
sector,
the
SBA
generally
defines
small
business
in
terms
of
number
of
employees;
in
the
agriculture,
mining,
and
electric,
gas,
and
sanitary
services
sectors,
the
SBA
generally
defines
small
businesses
in
terms
of
annual
receipts
(
ranging
from
$
0.5
million
for
crops
to
$
25
million
for
certain
types
of
pipelines).
The
RFA
also
authorizes
an
agency
to
adopt
alternative
definitions
for
each
category
of
small
entity
"
which
are
appropriate
to
the
activities
of
the
Agency
after
proposing
the
alternative
definition(
s)
in
the
Federal
Register
and
taking
comment"
(
5
U.
S.
C.
secs.
601(
3)
­
(
5)).
In
addition
to
the
above,
agencies
must
consult
with
SBA's
Chief
Council
for
Advocacy
to
establish
an
alternative
small
business
definition.

This
screening
analysis
uses
the
following
definitions
of
small
entities
affected
by
the
LT2ESWTR:

A
"
small
business"
is
any
small
business
concern
that
is
independently
owned
and
operated
and
not
dominant
in
its
field
as
defined
by
the
Small
Business
Act
(
15
USC
632).
Examples
of
public
water
systems
(
PWSs)
within
this
category
include
small,
privately
owned
PWSs
and
for­
profit
businesses
where
provision
of
water
may
be
ancillary,
such
as
mobile
home
parks
or
day­
care
centers.

°
A
"
small
organization"
under
the
LT2ESWTR
is
any
not­
for­
profit
enterprise
that
is
independently
owned
and
operated,
not
dominant
in
its
field,
and
operates
a
PWS.
Examples
of
small
organizations
include
churches,
schools,
and
homeowners
associations.

°
A
"
small
governmental
jurisdiction"
is
a
city,
county,
town,
school
district,
or
special
district
with
a
population
of
less
than
50,000
(
5
USC
601)
that
operates
a
PWS.

The
LT2ESWTR
will
apply
to
all
PWSs
using
surface
water
and
GWUDI
as
a
source.
The
NAICS
code
for
PWSs
is
22131
(
Administration
of
Water
Supply
and
Irrigation
Programs)
and
State
agencies
that
include
drinking
water
programs
are
classified
as
92411
(
Administration
of
Air
and
Water
Resources
and
Solid
Waste
Management
Programs)
or
923312
(
Administration
of
Public
Health
Programs).
Ancillary
systems
(
i.
e.,
those
that
supplement
the
function
of
other
establishments
like
factories,
power
plants,
mobile
home
parks,
etc.)
cannot
be
categorized
in
a
single
NAICS
code.
For
ancillary
systems,
the
NAICS
code
is
that
of
the
primary
establishment
or
industry.

The
LT2ESWTR
contains
provisions
that
apply
to
PWSs
serving
fewer
than
10,000
people.
This
is
the
cut­
off
level
specified
by
Congress
in
the
1996
Amendments
to
the
Safe
Drinking
Water
Act
for
small
system
flexibility
provisions.
In
accordance
with
the
RFA
requirements,
EPA
proposed
using
this
alternative
definition
in
the
Federal
Register
(
63
FR
7620,
February
13,
1998),
requested
public
comment,
consulted
with
the
SBA,
and
expressed
its
intention
to
use
the
alternative
definition
for
all
future
drinking
water
regulations
in
the
Consumer
Confidence
Reports
regulation
(
63
FR
44511,
August
19,
1998).

W.
2.2
Determining
What
Number
Constitutes
a
Substantial
Number
This
initial
assessment
assumes
that
all
small
PWSs
that
use
surface
water
or
GWUDI
are
potentially
affected
by
the
rule,
approximately
11,820
small
entity
PWSs.
EPA
SBREFA
guidance
uses
the
following
criteria
to
determine
what
constitutes
a
substantial
number
of
affected
entities:
no
more
than
20
percent
of
small
systems
affected
by
a
rule
or
no
more
than
1,000
systems
affected
by
a
rule
may
experience
economic
impacts
of
1
percent
of
their
revenues
or
greater.
In
addition,
no
more
than
100
systems
may
experience
economic
impacts
of
3
percent
of
their
revenues
or
greater.
The
LT2ESWTR
falls
under
these
thresholds.

W.
2.3
Measuring
Significant
Impacts
To
evaluate
the
impact
that
a
small
entity
is
expected
to
incur
as
a
result
of
the
rule,
this
analysis
calculates
the
entity's
annualized
compliance
costs
as
a
percentage
of
sales
(
for
privately
owned
systems)
or
the
entity's
annualized
compliance
costs
as
a
percentage
of
annual
governmental
revenue
or
expenditures
(
for
publicly
owned
systems).
EPA
guidance
suggests
using
1
percent
as
a
threshold
for
determining
significance,
although
additional
factors
may
be
considered.
If
compliance
costs
are
less
than
1
percent
of
sales
or
revenues,
the
regulation
may
in
most
cases
be
presumed
to
have
no
significant

impact
(
U.
S.
House
of
Representatives
1996).
In
addition,
if
no
more
than
100
systems
experience
economic
impacts
of
3
percent
of
their
revenues
or
greater,
than
in
most
cases
there
is
no
significant
impact.

Exhibit
W.
1
presents
the
data
EPA
used
for
the
screening
analysis
to
determine
if
the
LT2ESWTR
will
have
a
substantial
impact
on
a
significant
number
of
small
entities.
Using
this
data,
EPA
calculated
the
annual
compliance
costs
per
system
as
a
percentage
of
revenues
or
expenditures.
These
percentages
are
presented
in
Column
D.
The
numbers
of
systems
expected
to
incur
costs
of
more
than
1
and
3
percent
of
their
revenues
are
presented
in
Columns
E
and
G,
respectively.
The
numbers
of
systems
experiencing
impacts
of
more
than
1
and
3
percent
of
their
revenues
were
compared
to
the
total
number
of
systems
in
each
size
category
to
calculate
percentages,
shown
in
Columns
F
and
H.

The
ratio
of
compliance
cost
to
revenue
was
calculated
using
the
80th
percentile
of
annualized
(
at
3
percent)
compliance
costs
and
the
average
annual
revenue.
The
average
revenue
for
all
was
used
for
all
systems
and
size
categories
because
no
information
on
the
distribution
of
annual
revenues
was
available.
The
resulting
overall
cost­
to­
revenue
ratio
for
all
small
entity
PWSs
was
0.14
percent.
The
use
of
the
80th
percentile
compliance
cost
to
determine
the
ratio
implies
that
80
percent
of
systems
affected
by
the
LT2ESWTR
have
lower
compliance
costs,
and
therefore,
80
percent
of
systems
have
ratios
of
even
less
than
0.14
percent.
Thus,
the
threshold
of
20
percent
of
systems
having
costs
as
percentages
of
revenues
of
1
percent
or
more
is
not
exceeded.

Further,
EPA
determined
that,
based
on
the
80th
percentile
annualized
compliance
costs,
a
total
of
274
small
entity
PWSs,
representing
2.3
percent
of
all
small
entity
PWSs
affected
by
the
LT2ESWTR,
will
experience
an
impact
of
1
percent
or
greater
of
average
annual
revenues.
This
is
less
than
the
criteria
of
1,000
systems
or
20
percent
of
systems
used
to
determine
significant
impact.
Within
each
class
of
small
entity,
the
number
of
PWSs
experiencing
an
impact
of
1
percent
or
greater
of
average
annual
revenues
ranges
from
13
(
small
organization
PWSs)
to
140
(
small
government
PWSs),
which
is
1.2
to
2.4
percent
of
the
systems
in
each
category.

Further,
the
Agency
has
determined
that
31
small
entity
PWSs,
representing
0.3
percent
of
all
small
entity
PWSs
subject
to
the
LT2ESWTR,
will
experience
an
impact
of
3
percent
or
greater
of
average
annual
revenues.
This
is
less
than
the
criterion
of
100
systems
used
to
determine
significant
impact
at
this
cost
level.
Considering
each
class
of
small
entity,
the
number
of
PWSs
experiencing
an
impact
of
3
percent
or
greater
of
average
annual
revenues
ranges
from
1
(
small
organization
PWS)
to
15
(
small
government
PWSs),
which
is
0.1
to
0.3
percent
of
the
systems
in
each
category,
respectively.

With
respect
to
different
size
categories,
no
small
entity
PWSs
serving
500
or
fewer
people
and
fewer
than
0.8
percent
of
systems
serving
501
to
3,300
people
will
experience
an
impact
of
1
percent
or
greater
of
average
annual
revenues.
Approximately
6.0
percent
of
small
organization
PWSs
and
12.2
percent
of
small
government
and
business
PWSs
serving
3,301
to
10,000
people
will
experience
an
impact
of
1
percent
or
greater
of
revenues.

EPA
also
estimated
the
annual
revenues
or
expenditures
of
small
PWSs,
presented
in
Column
B
of
Exhibit
W.
1.
PWS
inventories,
managed
by
EPA
and
other
organizations,
have
traditionally
been
categorized
by
size
and
by
the
characteristics
of
the
population
served
(
i.
e.,
CWSs,
NTNCWSs,
and
TNCWSs)
rather
than
by
NAICS
code.
Revenues
by
NAICS
code
are
not
readily
applicable
to
EPA's
categorization
of
systems.
Therefore,
alternative
methods
for
determining
revenue
were
developed,
as
discussed
below.

The
estimated
revenues
for
small
entities
in
Exhibit
W.
1
are
from
the
Bureau
of
the
Census
(
U.
S.
Department
of
Commerce
1992),
the
Safe
Drinking
Water
Information
System
(
SDWIS),
and
additional
data
on
independent
privately
owned
CWSs,
special
districts,
and
authorities
from
the
1995
Community
Water
System
Survey
(
USEPA
1997c).
Column
A
of
Exhibit
W.
1
shows
the
numbers
of
systems
classified
as
small
businesses,
governments,
and
organizations,
obtained
using
information
from
the
Third
Edition
of
the
Baseline
Handbook
(
USEPA
2001c).
These
numbers
were
used
to
determine
the
weighted
averages
of
estimated
revenue.
Column
B
shows
the
estimated
revenues.

Small
government
systems
include
municipal,
county,
state,
federal,
military,
and
special
district
systems.
Data
on
revenue
for
townships
and
municipalities
were
obtained
from
the
1992
Census
of
Governments
(
U.
S.
Department
of
Commerce
1992),
converted
to
2000
dollars
by
applying
a
conversion
factor
calculated
from
the
national
income
and
product
account
tables
of
the
U.
S.
Bureau
of
Economic
Analysis.

Specifically,
the
price
deflators
for
1992
and
2000
were
obtained
from
Chain­
Type
Price
Indexes
for
State
and
Local
Governments
(
U.
S.
Department
of
Commerce
2002).
The
average
revenue
for
all
small
governments
with
PWSs
was
calculated
at
$
2,434,200.

Small
business­
run
PWSs
in
Exhibit
W.
1
include
both
CWSs
and
NTNCWSs,
such
as
privately
owned
CWSs,
mobile
home
parks,
country
clubs,
hotels,
manufacturers,
hospitals,
and
other
establishments.
For
this
analysis,
all
hospitals
and
day
care
centers
are
assumed
to
be
businesses,
as
are
50
percent
of
systems
classified
as
"
other."
2
Estimated
average
revenue
for
the
small
businesses
affected
by
the
LT2ESWTR
is
$
2,391,978.

Small
organizations
include
primarily
nonprofit
NTNCWS
such
as
schools
and
homeowners
associations.
The
revenue
estimates
for
small
nonprofit
organizations
serving
more
than
500
people
are
actually
higher
than
those
for
small
businesses
because
the
total
number
of
such
systems
is
small,
and
a
large
proportion
of
these
organizations
are
schools
and
colleges
with
large
budgets.
This
category
also
includes
50
percent
of
systems
classified
as
"
other."
The
average
estimated
revenue
for
small
organizations
affected
by
the
LT2ESWTR
is
$
4,446,165.

EPA
also
calculated
the
average
estimated
revenue
for
all
small
entity
PWSs.
This
estimate
is
weighted
to
account
for
the
number
of
small
entity
PWSs
in
each
category
(
government,
business,
and
organization)
affected
by
the
LT2ESWTR.
This
overall
average
is
$
2,597,966.

Screening
Analysis
Results
As
part
of
its
screening
analysis,
EPA
evaluated
the
potential
economic
impact
of
the
rule
on
small
entities
by
comparing
compliance
costs
as
a
percentage
of
sales,
revenues,
or
operating
expenditures
for
each
small
entity
classification.
Based
on
the
information
presented
in
Exhibit
W.
1,
EPA
certifies
that
the
LT2ESWTR
will
not
lead
to
significant
economic
impacts
for
a
substantial
number
of
small
entities
and,
therefore,
is
not
required
by
the
RFA,
as
amended
by
SBREFA,
to
conduct
an
IRFA
or
a
FRFA.

As
shown
in
Exhibit
W.
1,
the
costs
associated
with
the
LT2ESWTR
in
the
80th
percentile
(
annualized
at
3
percent)
do
not
approach
1
percent
of
the
small
entity
PWSs'
average
annual
revenues
or
expenditures.
The
annualized
cost
for
all
small
entity
PWSs
for
the
80th
percentile
is
$
3,593.

fewer

the

threshold
of
20
percent
of

Taking
this

one
step
further,
EPA
evaluated
the
number
of
systems
that
are
above
the
1

for
each

based
on
the
80th

(

will
experience

greater
of

which
falls
below
the
criteria
of
1,000

or
20

In
addition,
only
31
small

PWSs
(
0.3

will
experience
an

greater,
which
falls
