Surface

Using
SWAT
The
surface
water
analytical
tool
(
SWAT)
is
the
primary
tool
used
by
EPA
to
predict
treatment
technology
changes
in
surface
water
systems
to
achieve
compliance
with
the
Stage
2
Disinfection
and
Disinfectants
Byproducts
Rule
(
DBPR).
Changes
in
treatment
technology
are
the
basis
for
calculating
national
cost
estimates
in
this
Economic
Analysis
(
EA).
SWAT
is
also
the
primary
tool
used
to
predict
changes
in
national
DBP
occurrence
levels
as
a
result
of
the
technology
changes.
Changes
in
average
DBP
occurrence
levels
are
used
to
quantify
benefits
(
specifically,
reduced
bladder
cancer)
of
the
Stage
2
DBPR.

Because
of
the
uncertainties
in
SWAT
as
described
in
this
appendix,
only
national­
level
data,
not
plant­
specific
results,
are
considered
when
developing
costs
and
benefits
estimates.
Moreover,
EPA
minimized
potential
biases
and
uncertainties
in
SWAT
by
selecting
a
4­
step
approach
to
estimate
changes
in
technologies
and
DBP
occurrence.
First,
SWAT
is
used
to
model
the
pre­
Stage
1
baseline.
Then
SWAT
models
changes
in
technology
and
DBP
occurrence
for
the
Stage
1
rule
from
the
Pre­
Stage
1
baseline
and
for
the
Stage
2
rule
from
the
Pre­
Sage
1
baseline.
Results
for
Stage
1
are
subtracted
from
results
for
Stage
2
to
estimate
the
incremental
change
from
Stage
1
to
Stage
2.
This
procedure
is
described
in
more
detail
in
Section
6.4.2.

The
purpose
of
this
appendix
is
to
review
the
major
components
in
the
Surface
Water
Analytical

SWAT),
summarize
SWAT
operations,
and
discuss
the
validity
of
SWAT

that
holds
inputs

for
SWAT
analyses.
Unlike

described
in
Section

ICR
data
in
AUX8
is
not
intended
to
be
modified
by
the

or

AUX8
was
populated
from

(
AUX1
is
the
primary
ICR

see
Chapter

of
this

In
some
cases,
plants
reported
changes
in
their
unit
processes
or
chemical
addition
inputs
during
the
ICR
period.
For
example
some
plants
installed
ozone
during
the
ICR
collection
period.
Also,
many
plants
change
disinfectant
type
from
chlorine
to
chloramines
during
the
year.
The
initial
technology
level
determination
and
disinfectant
type
for
a
plant
was
always
based
on
the
technology
or
disinfectant
that
was
reported
most
often.

Only
the
last
12
months
of
the
18­
month
ICR
collection
period
were
used
in
SWAT
to
avoid
seasonal
bias.
2
Ground
water
plants
generally
did
not
have
as
much
information
as
surface
water
plants
and
thus,
were
not
modeled
in
SWAT.
The
ICR
surface
plants
in
AUX1
were
screened
to
extract
only
those
with
at
least
one
month
of
all
required
SWAT
input
data
into
the
AUX8
database.
To
increase
the
number
of
plant­
months
that
could
be
processed
by
SWAT,
some
missing
raw
water
quality
data
were
estimated.
For
example,
missing
monthly
values
for
influent
pH,
hardness,
alkalinity,
and
ammonia
were
estimated
based
on
the
average
of
values
that
were
reported
in
AUX1
for
the
other
months.
Missing
monthly
raw
water
temperature
data
were
estimated
based
on
reported
temperature
data
from
other
points
in
the
plant
or
distribution
system
for
the

if
neither
value
was
provided
for

If
either
TOC
or
UVA
data
existed
for
a
plant
month,
the
missing
value
was
estimated
using
the
ratio
of
UVA
to
TOC
for
the
rest
of
the
plant­
months.

Of
the
350
surface
water
plants
in
the
ICR,
273,
or
approximately
78
percent,
had
at
least
one
month
with
all
required
data
for
SWAT
analyses.
There
is
a
potential
bias
resulting
from
the
exclusion
of
ICR
plants
from
the
analysis.
The
M­
DBP
TWG
determined,
however,
that
the
273
plants
evaluated
in
SWAT
adequately
capture
treatment
configuration
and
water
quality
conditions
of
all
ICR
surface
water
plants.

Plants
only
needed
one
valid
month
(
i.
e.,
one
month
with
all
required
parameters)
to
be
used
in
SWAT,
so
many
of
the
273
plants
used
do
not
have
complete
records
for
all
months.
Exhibit
A.

shows
the
extent
to
which
there
are
complete
plant­

records
in
SWAT.
Note
that
over
70
percent
of
plants
have
at

10
months
of
data,
and
more
than

percent
have

Water
Treatment
Plant
Model
The
WTP
Model
predicts
the
formation
of
DBPs
given
source
water
quality
conditions
and
water
treatment
plant
configuration.
It
consists
of
several
empirical
equations
that
predict
DBP
precursor
and
disinfection
behavior,
the
impact
of
water
treatment
plant
processes
on
water
quality,
and
concentrations
of
DBPs
in
the
distribution
system.
The
original
version
of
the
WTP
Model
was
developed
in
1992
(
Water
Treatment
Plant
Simulation
Program
Version
1.21
User's
Manual,
Malcolm
Pirnie
Inc.
June
1992).
In
2000,
the
WTP
Model
was
thoroughly
revised
by
Malcolm
Pirnie
Inc.,
under
EPA
funding
to
the
Center
for
Drinking
Water
Optimization
at
the
University
of
Colorado.
This
revision
included
incorporation
of
new
research
in
the
areas
of
DBP
precursor
removal
and
DBP
formation
during
chlorination,
ozonation,
and
chlorine
dioxide
addition.
The
extensions
and
modifications
to
the
original
model
have
been
documented
in
Solarik
et
al.
(
2000).

The
purpose
of
this
section
is
to
describe
how
DBP
precursors
and
other
related
parameters
were
modeled
through
a
treatment
plant
and
to
present
the
final
equations
used
by
the
WTP
Model
to
predict
DBP
concentrations.
The
last
subsection
includes
a
description
of
how
the
final
DBP
equations
are
used
for
different
treatment
plant
scenarios.
Section
A.
5
builds
on
this
section
by
explaining
how
the
DBP
equations
were
calibrated
using
ICR
data.

A.
2.3.1
Predicting
Changes
in
pH
The
WTP
Model
predicts
pH
changes
as
a
result
of
chemical
addition
during
coagulation
and
softening
using
thermodynamic
equilibrium
assumptions
in
a
closed
system
(
with
respect
to
carbon
dioxide
equilibrium).
This
may
not
be
an
entirely
accurate
assumption
since
a
water
treatment
plant
is
neither
a
perfectly
closed
system
because
it
is
open
to
the
atmosphere,
nor
a
perfectly
open
system
because
of
the
depths
of
the
basins.
The
WTP
Model
equations
to
predict
pH
changes
due
to
softening
do
not
account
for
the
kinetics
of
processes
such
as
calcium
carbonate
precipitation
or
carbon
dioxide
dissolution.
Consequently,
predictions
are
not
always
completely
accurate.
In
general,
the
WTP
Model
is
believed
to
slightly
over­
predict
the
depression
of
pH
due
to
coagulant
addition
(
Solarik
et
al.
2000).

Coagulation
pH
is
an
input
parameter
for
the
algorithms
that
calculate
settled
water
TOC
and
UVA.
The
over­
prediction
of
the
depression
in
pH
could
result
in
the
propagation
of
error
in
the
settled
water
quality.
However,
based
on
observed
data
from
several
water
treatment
plants,
these
errors
are
not
large
(
see
section
A.
5,
Model
Calibration).

A.
2.3.2
Predicting
TOC
Removal
In
the
earlier
(
1992)
version
of
the
Model,
TOC
removal
by
coagulation
was
predicted
using
an
empirically­
derived
equation
based
on
the
raw
water
TOC,
coagulant
dose,
and
the
coagulation
pH.
In
the
current
version
of
the
Model,
TOC
removal
is
predicted
using
a
semi­
empirical
sorption
model,
published
by
Edwards
(
1997).
Though
the
semi­
empirical
sorption
model
is
applicable
specifically
for
dissolved
organic
carbon
(
DOC)
removal,
it
has
been

divides
the

that
are

by

and
attributes
TOC

to
the

alone.

In
addition
to
TOC,
coagulant
dose,
and
the
coagulation
pH,
the
current
model
uses
certain
calculated
model
coefficients
and
the
Specific
UVA
(
SUVA),
which
is
the
ratio
of
UVA
to
the
DOC
concentration,
of
the
raw

as
inputs.

Predicting
UVA
Reduction
In
the
1992
version
of
the
WTP
Model,
the
equations
to
predict
UVA
removal
were
limited
by
small
data
sets.
The
new
equations
are
based
on
data
analysis
performed
on
the
AWWA/
WITAF
database
(
Tseng
et
al.
1996),
thereby
extending
the
data
sets
used
for
equation
development.

An
analysis
of
predictive
errors
for
the
UVA
removal
equations
was
performed
using
raw
water
data
from
the
AWWA/
WITAF
database
as
inputs
to
the
equations
and
comparing
the
WTP
Model
results
to
those
from
the
database.
The
analysis
concluded
that
the
equations
tend
to
over­
predict
UVA
removal.
Further,
the
errors
in
settled
water
UVA
predictions
are
greater
for
softening
than
for
coagulation.
However,
it
must
be
noted
that
the
data
set
used
for
verification
of
UVA
removal
by
softening
(
i.
e.,
from
the
AWWA/
WITAF
database)
is
very
limited.

WTP
Model
Equations
for
DBP
Formation
During
the
development
of
the
WTP
simulation
model
in
1992,
a
limited
number
of
research
reports
were
available
to
derive
predictive
equations
for
THM
formation
during
chlorination.
As
a
result,
the
1992
version
used
an
empirical
THM
formation
equation
that
was
based
on
chlorination
experiments

of
raw
(
i.
e.,

or

waters
only.
The
equation
was
originally
used
in
the
model
irrespective
of
chlorine
application
locations
throughout
the
water
treatment
plant.
Chlorination
conditions
on
which
this
original
THM
predictive
equation
was
based
included
conditions
that
are
experienced
in
water
plants
as
well
as
some
more
severe
chlorination
conditions
beyond
normal
practices
at
water
plants.

At
the
time
of
developing
the
revised
WTP
simulation
model
in
2000,
THM
predictive
equations
were
available
from
the
literature
that
represented
more
realistic
chlorination
conditions
at
various
stages
of
treatment.
Consequently,
different
THM
predictive
equations
were
used
for
predicting
THM
formation
in
raw
water
and
in
waters
after
various
levels
of
treatment.
This
section
discusses
the
different
sets
of
equations
used
by
the
WTP
Model
to
predict
DBP
formation.
It
includes
two
sets
of
equations
used
to
model
DBP
formation
as
a
result
of
(
1)
raw
water
chlorination
(
i.
e.,
water
not
subjected
to
any
treatment
other
than

and
(
2)

(

results
indicated
that

slightly
under­

the

and
slightly
over­

the

For

Using
the
DBP
Formation
Equations
for
Different
Chlorinating
Scenarios
DBP
formation
is
modeled
as
the
cumulative
formation
through
the
treatment
plant.
This
section
describes
how
the
two
sets
of
equations
presented
above
can
be
applied
to
different
treatment
plant
chlorination
scenarios.
Specifically,
the
following
are
discussed:

°
Pre­
chlorination
only
(
i.
e.,
chlorine
added
just
prior
to
coagulation)

°
Post­
chlorination
only
(
i.
e.,
a
single
point
of
chlorination
just
prior
to
filtration,
after
the
combined
treatment
of
coagulation,
flocculation,
and
sedimentation)

°
Pre­
and
Post­
chlorination
(
i.
e.,
two
points
of
chlorination
­
just
prior
to
coagulation
and
just
prior
to
filtration)

Exhibit
A.
3
(
presented
at
the
end
of
this
subsection)
shows
where
the
chlorine
is
assumed
to
be
applied
within
the
treatment
plant
for
the
pre­
and
post­
chlorination
scenarios
and
summarizes
how
DBP
formation
is
modeled.
Note
that
separate
equations
for
DBP
formation
in
distribution
systems
were
not
developed
 
the
distribution
system
is
considered
as
an
extension
of
the
treatment
plant,
and
formation
is
assumed
to
follow
the
same
kinetics
and
rates.

Pre­
Chlorination
Only
The
raw
water
model
equations
were
originally
used
to
predict
DBP
formation
for
plants
that
prechlorinated
only.
However,
research
by
Summers
et
al.
(
1998)
indicates
that
pre­
chlorination
just
before
or
after
rapid
mixing
results
in
less
DBP
formation
than
chlorination
of
raw
water
as
shown
in
the
original
studies.
To
better
predict
DBP
formation
post­
coagulation/
flocculation,
an
empirical
pre­
chlorination
factor
was
developed
to
account
for
the
decrease
in
DBP
formation
that
occurs
as
a
result
of
adding
chlorine
just
prior
to
the
rapid
mixers
relative
to
the
DBP
formation
that
occurs
as
a
result
of
adding
chlorine
to
the
raw
water:

As

the
raw

equations,
adjusted
using
the
pre­
chlorination
factors,
are
used
to
model
DBP
formation
through
the
sedimentation
process
(
prior
to
the
filters).
The
treated
water
model
is
used
to
predict
DBP
formation
through
the
filtration
process
and
into
the
distribution
system,
using
settled
water
quality
(
including
settled
water
chlorine
residual)
as
input
parameters.

Post­
Chlorination
Only
For
post­
chlorination
(
prior
to
filtration),
the
treated
water
model
was
applied,
with
the
settled
water
quality
and
chlorine
residual
after
sedimentation
being
the
inputs
to
the
model
equations.

Pre­
and
Post­
Chlorination
As
shown
in
Exhibit
A.
3,
the
raw
water
equations,
adjusted
using
the
pre­
chlorination
factors,
are
used
to
model
DBP
formation
from
the
raw
water
through
the
sedimentation
process
(
prior
to
the
filters).
The
treated
water
model
is
used
to
predict
DBP
formation
starting
after
sedimentation.
The
treated
water
model
is
adjusted
because
pre­
chlorination
will
result
in
lowering
the
UVA
of
the
settled
water
due
to
the
oxidation
of
the
UVA
by
the
chlorine.
The

from
the

Decision
Tree
Program
This
part
of
SWAT
determines
how
a
treatment
plant
is
modified
to
comply
with
defined
regulatory
alternatives.
First,
the
program
determines
if
an
individual
plant
can
be
modified
using
the
least
expensive
(
and
typically
least
effective)
technology
to
comply
with
the
regulatory
alternative.
If
not,
the
program
moves
to
the
next
least­
cost
technology.
This
process
continues
until
the
plant
achieves
compliance.
The
technology
selection
algorithm
can
therefore
be
described
as
a
"
least
cost"
based
approach.
The
program
receives
inputs
from
the
database
(
AUX8),
and
uses
the
WTP
Model
to
estimate
treated
water
quality
before
and
after
predicted
treatment
changes,
and
sends
results
back
to
the
database.

The
steps
involved
with
using
the
Decision
Tree
Program
are
presented
in
Exhibits
A.
4
and
A.
5
in
flow
chart
and
table
format.
The
starting
point
is
at
the
top
of
the
tree,
and
the
process
improvement
order
is
from
the
top
row
to
the
bottom
row
and
from
left
to
right
in
any
row.

For
each
technology
starting
with
Enhanced
Coagulation/
Enhanced
Softening
(
EC/
ES),
there
is
an
additional
option
of
chloramine
secondary
disinfection
with
that
technology.
For
example,
if
the
tree
starts
at
EC/
ES
technology
and
it
does
not
yield
compliance,
then
the
next
option
is
EC/
ES
with
chloramines.
One
important
aspect
of
the
decision
tree
is
how
it
accounts
for
existing
disinfection
credit.
To
implement
an
advanced
disinfectant
in
a
process
train,
SWAT
credits
the
train
with
the
levels
of
inactivation
specified
by
the
user
(
see
section
A.
4
for
user
inputs)
and
adjusts
the
existing
primary
disinfectant
to
achieve
the
necessary
CT
credit.
Any
other
chlorine
additions
contributing
to
CT
are
decreased,
if
necessary.

Stage
2
DBPR
Model
Runs
This
section
summarizes
the
inputs
and
settings
(
as
entered
into
the
SWAT
user
interface)
used
for
the
Stage
2
DBPR
regulatory
alternatives.
SWAT
was
also
used
to
support
the
development
of
the
Long
Term
2
Enhanced
Surface
Water
Treatment
Rule
(
LT2ESWTR).
Conditions
presented
here,
however,
are
specific
the
Stage
2
DBPR
development
process.
Those
specific
to
the
LT2ESWTR
are
described
in
the
Economic
Analysis
for
the
LT2ESWTR
(
USEPA
2003m)

Average
and
Maximum
Residence
Times
SWAT
computes
DBP
concentrations
at
theoretical
locations
representing
average
and
maximum
residence
times.
The
inputs
for
the
average
residence
time
location
(
DS
Average)
and
maximum
residence
time
(
DS
Maximum)
are
based
on
ICR
data
from
four
distribution
system
residence
times
reported
by
the
system
are
as
follows.

°
Distribution
System
Equivalent
(
DSE)
 
a
sample
point
in
the
distribution
system
that
has
a
residence
time
equivalent
to
a
laboratory
sample.

°
Average
1
and
Average
2
(
AVG1
and
AVG2)
 
two
locations
having
average
residence
times
in
the
distribution
system,
as
designated
by
the
system.

°
Distribution
System
Maximum
(
MAX)
 
location
having
the
longest
residence
time
in
the
distribution
system,
as
designated
by
the
system.

The
input
for
the
DS
Average
is
the
average
of
those
four
residence
times.
The
input
for
DS
Maximum
is
the
highest
residence
time
reported
for
those
four
locations.

Flowrate
Conditions
Used
Three
flowrate
conditions
are
available
for
SWAT
execution:
1)
flow
at
time
of
ICR
sampling;
2)
average
monthly
flow
for
a
given
ICR
period;
and
3)
plant
design
flow.
All
calculations
of
DBP
concentrations
were
completed
using
the
average
monthly
flow.
All
new
unit
processes
"
built"
by
SWAT
were
sized
using
the
design
flow
condition.

Inclusion
of
Biofiltration
All
Stage
2
DBPR
regulatory
evaluations
included
biofiltration
processes
for
ozone
technologies.
This
assumed
that
the
filters
downstream
of
ozonation
would
achieve
enhanced
DBP
precursor
removal.

Surface
Water
Treatment
Rule
Disinfection
Requirements
For
all
regulatory
alternatives,
the
plants
must
meet,
at
a
minimum,
the
Surface
Water
Treatment
Rule
(
SWTR)
Giardia
and
virus
log
removal
requirements
of
3
and
4
logs,
respectively.
The
"
Initial
Plant
Run"
did
not
have
this
requirement
since
it
represents
pre­
Stage
1
or
existing
conditions.
In
other
words,
if
SWAT
predicted
a
plant
to
achieve
lower
Giardia
or
virus
log
removals,
the
plant
was
not
modified
for
this
run.

Log

Log

were
based
on
(

the
recommended
credits
contained
in
the
Guidance
Manual
for
Compliance
with
the
Filtration

Disinfection
Requirements
for
Public

the
Microbial
Treatment
subcommittee
of
the
TWG
(
Exhibit

6).
Cryptosporidium
inactivation/
removal
requirements
were
not
included
(
they
are
considered
under
the
LT2ESWTR.
If
the

used
in

are
overstated
(
i.
e.,
the

then
the

Likewise,
if
the

then
the

Use

Benchmarking
Disinfection
benchmarking
is
the
SWAT
input
that
determines
the
disinfection
requirements
for
a
given
plant.
If
"
Benchmarking
OFF"
is
selected,
then
SWAT
selects
disinfectant
doses
to
meet
the
most
stringent
of
the
log
removal
and/
or
inactivation
requirements
set
for
the
regulatory
option.
If
"
Benchmarking
ON"
is
selected,
SWAT
determines
the
minimum
monthly
level
of
log
removal
plus
inactivation
for
each
plant
under
existing
conditions
and
sets
these
as
the
log
removal
plus
inactivation
requirements
for
that
plant
for
all
process
modifications.
If
the
benchmark
is
less
stringent
than
the
disinfection
requirements
set
for
that
SWAT
run,
SWAT
will
default
to
the
most
stringent
requirements.

All
Stage
2
DBPR
regulatory
evaluations
were
conducted
with
"
Benchmarking
ON."
Maximum
benchmark
levels
for
Giardia
and
viruses
were
set
at
8.0
and
9.0
logs,
respectively.
Cryptosporidium
disinfection
was
not
benchmarked
because
most
systems
currently
don't
achieve
any
Cryptosporidium
inactivation.
Using
the
"
Benchmarking
ON"
option
most
likely
causes
an
overall
higher
technology
selection
estimate.
Some
systems
may
use
a
high
dose
of
oxidant
for
other
reasons
(
e.
g.,
taste
and
odor
control);
the
high
level
of
disinfection
is
a
secondary
benefit.
In
the
SWAT
model,
if
a
plant
currently
has
a
high
oxidant
dose
and
DBP
estimates
that
are
over
the
user­
defined
MCLs,
then
the
next
technology
in
decision
tree
is
selected
and
the
same
high
level
of
inactivation
corresponding
to
the
annual
high
oxidant
dose
must
be
maintained.
However,
in
implementation
of
the
DBPR
the
State
may
allow
lower
disinfection
for
improved
DBP
control,
as
long
as
the
level
of
disinfection
is
higher
than
the
existing
standards.

Chloramine
Conversion
Rate
SWAT
can
evaluate
three
settings
for
the
conversion
of
free
chlorine
to
chloramines
for
secondary
or
residual
disinfection.

°
All
free
chlorine
plants
can
convert
°
No
free
chlorine
plants
can
convert
°
A
specified
percentage
of
free
chlorine
plants
can
convert,
and
are
assigned
randomly
through
a
Monte
Carlo
probability
function
For
regulatory
evaluation,
77
percent
of
free
chlorine
plants
were
randomly
allowed
to
convert
to
chloramines.
This
was
set
as
the
maximum
possible
conversion
rate
expected
for
all
free
chlorine
plants
in
the
United
States.
This
maximum
national
chloramine
usage
level
is
intended
to
reflect
site­
specific
circumstances
and
other
local
factors
that
would
preclude
chloramine
usage
at
some
plants
for
reasons
other
than
technical
suitability.
The
maximum
chloramine
conversion
rate
was
approached
only
when
more
stringent
regulatory
alternatives
(
i.
e.,
40/
30
RAA)
were
evaluated.

Use
of
UV
Adding
UV
disinfection
to
a
treatment
process
is
an
optional
step
in
the
SWAT
decision
tree.
Because
UV
is
an
emerging
technology
for
drinking
water
treatment
it
was
not
considered
a
viable
option
for
Stage
1
compliance.
However,
EPA
believes
the
technology
and
necessary
regulations
will
be
available
for
systems
to
use
UV
to
achieve
compliance
with
the
Stage
2
DBPR.
Therefore,
the
UV
option
was
"
turned
off"
for
the
Stage
1
DBPR
run
and
"
turned
on"
for
the
Stage
2
DBPR
runs.
(
See
Chapter
6
for
further
discussion
on
the
inclusion
of
UV
for
the
Stage
2
runs.)

Clearwell
Baffling
Improvement
Rate
For
regulatory
evaluation,
90
percent
of
plants
were
assumed
able
to
make
improvements
to
clearwell
baffling.
The
TWG
assumed
that
a
0.70
value
for
the
clearwell
baffling
factor
(
the
ratio
of
the
time
required
for
10
percent
of
a
system's
flow
to
pass
through
the
clearwell
to
the
theoretical
detention
time
in
the
clearwell)
was
a
reasonable
upper
limit
for
improvements
to
hydraulic
retention
through
such
basins.
An
analysis
of
the
ICR
data
on
clearwell
baffling
factors
showed
that
10
percent
of
ICR
plants
had
baffling
factors
at
or
above
0.70.
Therefore,
the
remaining
90
percent
of
the
plants
could
improve
their
clearwell
hydraulic
regime
to
attain
such
a
baffling
factor.
While
SWAT
allowed
90
percent
of
the
plants
to
increase
the
hydraulic
retention
time
performance
of
clearwells,
it
did
not
require
plants
to
do
so
in
evaluating
regulatory
alternatives.
The
clearwell
baffling
factor
was
considered
only
when
increased
disinfection
performance
was
necessary
and
could
be
achieved
by
such
measures.

Nanofiltration
Performance
for
Precursors
Nanofiltration
performance
for
precursors
was
assigned
based
on
ICR
Treatment
Studies
data,
representing
the
median
performance
of
nanofilters
for
precursor
control.
The
performance
and
operating
parameters
were
assigned
as

Regeneration
Frequency
When
the
decision
tree
program
chooses
GAC10
or
GAC20
as
the
next
feasible
technology
to
achieve
compliance,
it
adopts
the
following
sequence
of
reactivation
frequencies
to
check
for
compliance:
An
initial
evaluation
with
a
reactivation
frequency
of
360
days,
followed
by
reactivation
frequencies
of
300,
240,
180,
120,
and
90
days
in
that
specific
order,
until
the
plant
is
in
compliance.
The
TWG
verified
that
the
cost
hierarchy
of
the
compliance
decision
tree
was
maintained
under
this
sequence.

Turbo
Coagulation
Turbo
coagulation
is
a
technology
that
achieves
increased
TOC
removal
with
coagulant
doses
higher
than
those
required
by
enhanced
coagulation.
A
(
4x3)
matrix
of
raw
water
TOC
and
alkalinity
defines
the
percent
TOC
removal
in
SWAT.
The
default
turbo
coagulation
setting
used
in
SWAT
represents
the
75th
percentile
ICR
values
for
a
given
raw
water
TOC­
alkalinity
category
(
25
percent
of
ICR
water
treatment
plants
in
a
given
raw
water
TOC­
alkalinity
category
achieved
TOC
removal
greater
than
or
equal
to
the
specified
level).
Exhibit
A.
7
shows
the
additional
TOC
removal
achieved
with
turbo
coagulation
at
these
settings.

To
determine
if
turbo
coagulation
was
a
viable
treatment
alternative,
the
ICR
data
were
analyzed
to
see
if
additional
TOC
removal
was
possible.
For
surface
water
plants
with
conventional
treatment
(
non­
softening
plants),
the
TOC
removal
was
found
for
each
month
where
available
data
existed.
Each
plant
was
characterized
within
the
Stage
1
DBPR
enhanced
coagulation
matrix
for
TOC
removal,
based
on
the
annual
average
source
water
alkalinity
and
TOC.
The
distribution
of
annual
average
TOC
removal
for
ICR
plants
was
determined
for
each
alkalinity
and
TOC
category
in
the
matrix.
The
median
performance
of
the
plants
within
each
of
the
categories
was
found
to
be
very
close
to
the
TOC
removal
requirements
in
the
Stage
1
DBPR.
Therefore,
the
ability
of
such
plants
to
achieve
even
more
TOC
reduction
by
further
enhancing
their
treatment
performance
was
considered
a
viable
treatment
alternative.

SWAT
did
not
require
any
plants
to
meet
the
TOC
removal
performance
criteria
contained
in
the
turbo
coagulation
step,
but
allowed
conventional
plants
to
further
optimize
TOC
removal
as
a
means
of
meeting
DBP
requirements.
The
inclusion
of
the
turbo
coagulation
treatment
step
contributes
to
more
realistic
national
compliance
costs
by
reducing
the
number
of
plants
requiring
more
advanced,
but
possibly
unnecessary,
technologies
to
meet
DBP
standards.

Regulatory

at

points
in

where
the

For
regulatory
evaluation,
the
bromate
MCL
was
determined
using
an
annual
average
of
predicted

point.
The
chlorite
MCL
was
determined
as
a

The

recommended
that
a

percent

factor
be
used
for
DBP
MCLs
(
TTHM,
HAA5,
bromate,

when
evaluating
all
regulatory
alternatives.
This
safety
factor
is
consistent
with
practices
in

and
is
intended
to
represent
the
level
at
which

to
take
some
action
to
ensure
compliance
with
a

In
addition
to
reflecting

practices,
the

also
is
intended
to
account
for
year­

in
DBP

(
ICR

Uncertainties
in
Compliance
Determination
This
section
details
the
areas
of
uncertainty
with
respect
to
SWAT
compliance
determination.
See
section
A.
6
for
a
summary
of
all
uncertainties
associated
with
using

predictions
for

benefit
and
cost
calculations.

Use
of
an
Operational
Safety
Factor
in
Setting
DBP
MCLs
The
use
of
a
safety
factor
increases
the
number
of
plants
affected
by
a
regulatory
alternative,
shifts
the
technology
selection
to
more
advanced
technologies,
and
increases
the
average
reduction
in
DBPs
due
to
the
Stage
2
DBPR.
As
noted
in
the
previous
section,
EPA
believes
that
use
of
a
safety
factor
generally
reflects
industry
practices
based
on
recommendations
from
the
MDBP
TWG.
There
is
uncertainty,
however,
in
the
concentration
below
the
MCL
value
at
which
systems
are
confident
operating
(
e.
g.,
the
safety
factor
may
be
more
or
less
in
some
cases).

To
assess
the
potential
impact
of
uncertainties
in
the
operational
safety
factor,
an
analysis
was
performed
to
compare
post­
Stage
1
technology
predictions
generated
with
a
safety
factor
to
predictions
based
on
no
safety
factor.
Results
displayed
in
Exhibit
A.
9
show
that
12
percent
more
surface
water
plants
are
predicted
to
install
some
form
of
treatment
to
comply
with
the
Stage
1
DBPR
MCLs
when
a
20­
percent
safety
factor
was
used
compared
to
no
safety
factor
being
applied.
Further,
granular
activated
carbon
 
20­
minute
contact
time
(
GAC20)
and
integrated
membrane
technologies
were
selected
only
when
the
safety
factor
was
applied.
Using
a
safety
factor
larger
than
20
percent
would
cause
even
more
systems
to
select
advanced
technologies.

While
there
is
still
uncertainty
related
to
using
an
operational
safety
factor
of
20
percent,
EPA
believes
that
this
recommended
value
is
a
reasonable
representation
of
true
operating
conditions
at
a
utility
and
that
the
error
introduced
by
different
safety
factors
being
used
by
systems
is
small.

The

require
that

sample
from
a
certain
number
of
distribution
system
monitoring
locations
for
each
plant
in
their
distribution

The
required
number
of
monitoring
locations
varies
by
system
source
water
type
and
size
(
e.
g.,
4
monitoring
locations
are
required
for
large
surface
water
systems).
Although
monitoring
requirements
are
on
a
per­
plant
basis,
compliance
with
Stage
1
and
2
MCLs
are
based
on
system­
wide
TTHM
and
HAA5
monitoring
results.
Because
not
all
plants
in
a
given
system
were
available
for
SWAT
modeling,
SWAT­
predicted
DBP
results
for
each
plant
are
evaluated
separately
to
determine
regulatory
compliance.

The
effect
of
using
a
plant­
level
analyses
in
SWAT
to
predict
system­
level
compliance
is
discussed
below
for
three
alternative
compliance
calculations
(
RAA,
LRAA,
and
single
highest).
Results
show
that
uncertainties
introduced
by
plant­

exist
only
for
the
RAA
compliance
calculation.

°
RAA
 
In
systems
with
multiple
plants,
high
DBP
results
from
one
plant
could
be
averaged
with
low
DBP
results
from
other
plants
to
produce
a
system­
level
RAA
that
is
below
the
MCL,
even
if
the
one
plant
would
exceed
the
MCL
if
evaluated
alone.
For
example,
say
that
plant
A
is
a
surface

plant
with
a
TTHM
RAA
of
85

are

respectively.
Assuming
that

samples,
the

RAA
would
be
(

separately,
SWAT
could

that
a

needed
to
make
a
technology
change
when
in
fact,
it
is
within
a
system
that
is
in
compliance.

°
LRAA
 
Unlike
the
RAA,
the
LRAA
measure
evaluates
compliance
for
each
individual
monitoring
location.
If
a
plant
has
an
LRAA
over
the
MCL,
then
both
the
plant­
level
and
system­
level
analysis
will
show
the
system
out
of
compliance.

°
Single
highest
 
Similar
to
the
LRAA,
compliance
with
a
single
highest
value
will
target
each
individual
monitoring
location.
If
a
plant
has
a
single
highest
value
over
the
MCL,
then
both
the
plant­

and

analysis
will
show
the
system
out
of

The
Effect
of
Switching
From
Surface
Water
to
Ground
Water
on
Compliance
Determination
Some
ICR
plants
reportedly
switched
from
surface
to
ground
water
sources
during
different
times
of
the
year.
DBP
results
for
the
ground
water
use
periods
were
not
included
in
SWAT.
Switching
from
a
surface
to
a
ground
water
source
would
most
likely
decrease
TTHM
and
HAA5
formation
and
would
impact
RAA
and
LRAA
compliance
calculations.
Not
accounting
for
ground
water
use
periods
could
result
in
an
over­
prediction
in
the
compliance
forecast
predicted
by
SWAT.

Description
of
WTP
Calibration
Process
and
Results
The
WTP
Model
was
calibrated
to
improve
its
ability
to
predict
the
central
tendency
of
the
ICR
data.
There
are
several
reasons
why
the
SWAT­
predicted
DBP
concentrations
do
not
necessarily
concur
with
the
ICR­
observed
data.
These
are
summarized
below
(
a
summary
discussion
of
these
uncertainties
in
SWAT
and
their
effects
on
the
Stage
2
DBPR
cost
and
benefits
estimates
are
presented
in
sections
A.
6
and
A.
7):

1)
The
WTP
Model
uses
generic
treatment
process
configurations
to
represent
real
ICR
plants.
For
example,
the
Model
represents
a
conventional
treatment
process
train
using
a
specific
configuration
of
the
pertinent
unit
processes.
However,
ICR
plants
employing
conventional
treatment
could
have
a
slightly
different
configuration
from
the
generic
conventional
treatment
plant
used
by
the
WTP
Model.

2)
The
WTP
Model
uses
empirical
equations
(
based
mainly
on
bench­
scale
tests)
to
predict
DBP
concentrations.
However,
it
does
not
take
into
account
site­
specific
factors
such
as
non­
uniform
flow
within
a
plant,
actions
of
microbes,
etc.
As
a
result,
the
predicted
finished
water
DBP
concentration
is
likely
to
be
different
from
the
ICR
observed
data.

3)
The
accuracy
of
residence
time
estimates
for
ICR
distribution
system
sample
locations
depends
on
operator
experience
with
the
system
and
the
extent
to
which
distribution
system
modeling
or
tracer
studies
have
been
conducted.
Furthermore,
residence
fluctuates
at
any
given
location
in
the
distribution
system,
and
the
ICR
sample
may
not
reflect
the
typical,
or
average
residence
time
at
that
location.
Because
DBP
formation
(
particularly
TTHM
formation)
is
highly
dependent
on
the
residence
time,
uncertainty
in
residence
time
inputs
would
result
in
inaccurate
estimates
of
DBP
concentration
by
the
WTP
Model.

4)
ICR
quarterly
samples
were
not
necessarily
collected
at
evenly
spaced
intervals
(
a
minimum
of
two
months
was
required
between
quarterly
samples;
however,
samples
were
not
required
Economic
Analysis
for

DBPR
Proposal
A­
26
July
2003
to
be
taken
approximately
90
days
apart,
as
required
in
the
Stage
2
DBPR).
Thus,
a
single
sample
may
not
be
wholly
representative
of
that
quarter,
especially
if
the
seasonal
influence
is
strong.

5)
The
WTP
Model
predicts
the
quality
of
a
particular
slug
of
water
from
the
source
through
the
treatment
plant
and
distribution
system.
It
is
unlikely
that
ICR
monthly
samples
reflect
the
same
slug
of
water
at
these
locations.

6)
Although
rigorous
quality
assurance
procedures
were
followed
during
the
ICR
data
collection,
there
still
may
be
reporting
errors
in
the
ICR
data
set
as
well
as
errors
that
could
have
occurred
during
the
upload
of
data
into
the
Model.

7)
Missing
records
in
the
ICR
resulted
in
fewer
plant­
months
being
selected
for
calibration
(
see
Section
A.
2.1
for
a
description
of
how
plants
were
screened
and
how
some
missing
data
were
"
filled
in"
in
AUX8).

In
spite
of
these
differences
in
the
data
sets,
the
TWG
believed
that
calibrating
the
Model
outputs
to
the
central
tendency
of
the
ICR
data
was
appropriate
for
generating
national­
level
predictions
of
treated
water
quality.

methodology
and
results
of
the
calibration
process
can
be
found
in
Chapter

of
the

EPA
believes
that
it
is
important
to
summarize
results
of
the
calibration
in
this
economic
analysis
to
help
characterize
uncertainties
in
SWAT.
The
remainder
of
this
section
summarizes
the
WTP
Model
calibration
process
and
present
the
results.

A.
5.1
Calibration
Methodology
Water
Quality
Parameters
that
were
calibrated:
The
calibration
process
focused
on
the
following
parameters:

°
pH
adjustment
(
in
softening
and
non­
softening
plants)

°
TOC
removal
(
in
softening
and
non­
softening
plants)

°
Free
chlorine
decay
°
Chloramine
decay
°
THM
and
HAA
formation
with
free
chlorine
(
in
treatment
plant
and
distribution
systems)

°
THM
and
HAA
formation
with
chloramines
The
Model
algorithms
were
calibrated
starting
with
pH
and
ending
with
DBPs
since
the
algorithms
in
some
of
the
processes
in
the
above
list
use
inputs
from
algorithms
for
processes
preceding
them.

Note
that
calibration
was
not
performed
for
DBP
formation
for
plants
using
chlorine
dioxide
or
ozone
due
to
the
lack
of
sufficient
number
of
data
sets.
This
introduces
uncertainty

(

for

Data
Set
Used
for
Calibration:
Although
the
ICR
database
contains
data
from
350
large
surface
water
treatment
plants
across
the
US,
only
a
subset
of
those
records
were
used
for
calibrating
the
WTP
Model.
The
following
rules
were
applied
to
this
subset
of
ICR
plants,
which
further
reduced
the
number
of
plants/
plant­
month
records
used
for
the
calibration
analysis:

1)
To
avoid
seasonal
bias,
the
calibration
analysis
used
the
last
12
months
of
ICR
data
(
i.
e.,
from
January
to
December
1998),
instead
of
all
18
months.

2)
Plants
using
unit
processes
such
as
air
stripping
or
process
configurations
such
as
mid­
stream
blending
were
excluded,
since
the
WTP
Model
was
unable
to
handle
those.

3)
Plant­
month
records
with
missing
water
quality
or
treatment
train
parameters
were
excluded
from
the
analysis.

4)
Plant­
months
with
predicted
finished
water
alkalinities
less
than
zero
were
excluded
from
further
consideration
(
see
step
1
of
the
calibration
approach
discussed
below).
A
finished
water
alkalinity
of
less
than
zero
indicated
erroneous
chemical
dosages
(
most
likely
errors
with
the
units).
Hence,
these
plant­
months
were
excluded.

Calibration
Approach:
The
calibration
approach
is
summarized
by
the
following
steps:

1)
Generate
uncalibrated
model
predictions,
which
are
stored
in
AUX
8
along
with
the
observed
data.
Plant­
months
with
predicted
finished
water
alkalinity
less
than
zero
were
eliminated
from
further
consideration.

2)
Queried
predicted
and
observed
data
were
from
appropriate
plant­
months
in
AUX8.

3)
Calculated
absolute
residuals,
i.
e.,
the
absolute
value
of
the
difference
between
observed
and
predicted
data
for
a
particular
parameter.

4)
Exclude
observed
and
predicted
data
pairs
with
the
highest
10
percent
of
absolute
residuals
for
the
parameter
being
calibrated
from
further
consideration.
This
was
done
to
ensure
that
the
extreme
outliers
in
the
ICR
data
didn't
skew
the
calibration
of
the
WTP
Model.

5)
Generate
scatter
plots
of
predicted
verus
observed
data
for
a
given
parameter
to
identify
if
calibration
adjustments
were
required.
To
determine
whether
a
calibration
factor
was
required,
a
line
of
best
fit
forced
through
the
origin
was
applied
to
the
scatter
plot.
If
the
slope
of
that
line
was
within
5
percent
of
unity,
no
calibration
factor
was
applied.
If
the
above
were
not
true,
one
of
the
following
two
calibration
adjustments
was
applied:

(
a)
Slope­
based
adjustment:
This
was
applied
when
the
best­
fit
line
not
forced
through
the
origin
had
an
intercept
close
to
zero.
Calibration
was
then
performed
using
the
best­
fit
line
forced
through
the
origin.
If
the
slope
of
this
line
was
beyond
5
percent
of
unity,
a
multiplicative
calibration
factor
equal
to
the
inverse
of
this
slope
was
applied
to
the
appropriate
WTP
algorithm.

Slope
and
intercept­
based
adjustment:
This
was
applied
when
a
clear
linear
relationship
existed
between
the
observed
and
predicted
values
and
the
best­
fit
line
not
forced
through
the
origin
did
not
have
an
intercept
close
to
zero.
In
such
cases,
there
was
a
clear
trend
of
under­
prediction
at
one
end
and
over­
prediction
at
the
other
end.
The
slope
and
intercept
of
the
best­
fit
line
were
then
used
to
calibrate
the
appropriate
WTP
algorithm.

Model
Performance
Evaluation:
After
the
Model
was
calibrated,
its
performance
was
evaluated
as
follows:

1)
The
WTP
Model
was
re­
run
to
generate
a
set
of
calibrated
predictions.

2)
Observed
and
predicted
(
new)
data
were
queried
from
AUX8
for
the
same
plant
subsets,
and
scatter
plots
were
constructed.
The
square
of
the
correlation
coefficient
(
i.
e.,
r2)
was
calculated
for
the
scatter
plots
to
assess
the
predictive
performance
of
the
Model.
An
r2
value
of
close
to
unity
indicates
a
strong
correlation
between
the
observed
and
predicted
data,
and
thus
a
better
predictive
performance
of
the
Model.

3)
Cumulative
distributions
of
all
data
observed
(
without
the
exclusion
of
any
data
pairs
as
described
in
step
5
above)
were
compared
to
cumulative
distributions
of
predicted
data
to
assess
the
ability
of
the
Model
to
predict
full­
scale
treatment
performance
on
a
national
level.

4)
Paired
data
were
analyzed
to
investigate
the
Model's
correlation
with
site­
specific
ICR
observations.
This
was
achieved
by
calculating
residuals
(
i.
e.,
SWAT
predicted
minus
ICR
observed
value)
for
paired
data
for
each
water
quality
parameter.

5.3
Discussion
of
the
Calibration
Results
for
each
Parameter
1.
pH:

Softening
plants:
An
adjustment
in
the
slope
and
the
intercept
was
required
in
this
case
(
i.
e.,
pH
cal
=
(
pH
orig
­
1.86)
÷
0.71).
After
calibration,
the
r2
of
the
scatter
plot
increased
from
0.33
to
0.37.
The
slope
of
the
best­
fit
line,
forced
through
the
origin,
was
within
5
percent
of
unity.
This
indicated
that
the
observed
and
predicted
data
pairs
were
more
symmetrically
distributed
around
the
line
with
a
slope
of
unity,
after
calibration.

Non­
softening
plants:
No
calibration
was
required
since
the
slope
of
the
best­
fit
line,
forced
through
the
origin,
was
very
close
to
unity
(
i.
e.,
0.98).
The
r2
of
the
scatter
plot
was
substantially
higher
than
that
of
the
softening
plants
(
i.
e.,
0.69),
indicating
a
strong
correlation
between
the
data
pairs.

2.
TOC:

Softening
plants:
A
slope
adjustment
was
required
in
this
case
(
i.
e.,
TOC
cal
=
TOC
orig
÷
0.87).
After
the
calibration,
the
r2
of
the
scatter
plot
was
0.58,
thus
indicating
a
fairly
strong
correlation
between
the
data
pairs.

Non­
softening
plants:
No
calibration
was
required
since
the
slope
of
the
best­
fit
line,
forced
through
the
origin,
for
the
uncorrected
predicted
data,
was
very
close
to
unity.
The
r2
of
the
scatter
plot
was
the
highest
among
all
the
parameters
investigated
(
i.
e.,
0.84),
indicating
a
very
strong
correlation
between
the
data
pairs.

A
comparison
of
the
distributions
of
the
observed
and
predicted
(
after
calibration)
data
(
including
data
from
both
softening
and
non­
softening
plants)
indicated
that:

°
Predicted
values
at
the
75th
percentile
or
below
exceeded
observed
values
by
only
0.1­
0.2
mg/
L.

°
The
Model
predictions
were
generally
slightly
higher
than
the
observed
values.

3.
Free
Chlorine:

No
calibration
was
required
since
the
slope
of
the
best­
fit
line,
forced
through
the
origin,
for
the
uncorrected
predicted
data,
was
within
5
percent
of
unity.
The
r2
of
the
scatter
plot
was
0.49,
indicating
a
reasonable
correlation
between
the
data
pairs.

4.
Chloramine:

No
calibration
adjustment
was
made
in
this
case
even
though
the
slope
of
the
best­
fit
line
forced
through
the
origin
(
for
the
uncorrected
predicted
data)
was
not
within
5
percent
of
unity.
The
reasons
for
this
are:

°
The
predicted
and
observed
data
were
weakly
correlated
to
start
with
(
since
r2
=
0.21).
Consequently,
multiple
attempts
at
calibration
failed
to
produce
a
desirable
improvement.

°
The
combined
effects
of
the
errors
in
reported
dosages
of
chlorine
and
ammonia
(
required
for
chloramine
formation)
compounded
the
errors
in
the
predicted
chloramine
residual.

°
Chloramine
residual
is
not
a
critical
parameter
and
is
rarely
used
to
achieve
disinfection
credit.

Paired
data
analysis
indicated
that
a
substantial
spread
in
the
distribution
of
the
residuals
(
see
Exhibit
A.
10),
although
an
evaluation
of
the
observed
and
predicted
distributions
indicated
that
the
median
values
matched
reasonably.

5.
TTHM:

For
plants
using
chlorine
in
the
distribution
system,
modeled
TTHM
formation
was
calibrated
using
observed
ICR
data
from
the
finished
water
location
and
calculated
distribution
system
average
(
or
RAA).
For
plants
using
chloramines,
the
DBP
formation
is
estimated
as
a
percent
of
the
predicted
TTHM
in
plants
using
free
chlorine.
Results
from
the
calibration
of
TTHM
formation
under
different
disinfection
scenarios
is
summarized
below:

°
TTHM
formation
at
the
finished
water
location
when
disinfecting
with
chlorine
in
the
treatment
plant
and
the
distribution
system:
A
slope
adjustment
was
required
in
this
case
(
i.
e.,
TTHM
cal
=
TTHM
orig
÷
0.77).
After
the
calibration,
the
r2
of
the
scatter
plot
was
0.50,
thus
indicating
a
reasonable
correlation
between
the
data
pairs.

°
TTHM
formation
at
the
DS
Average
location
when
disinfecting
with
chlorine
in
the
treatment
plant
and
the
distribution
system:
The
slope
adjustment
factor
of
0.77
(
from
the
TTHM
in
finished
water
case
described
above)
was
applied
to
the
data
set
for
the
DS_
AVG
location
(
i.
e.,
TTHM
cal
=
TTHM
orig
÷
0.77).
After
the
calibration
adjustment,
the
r2
and
the
slope
of
the
scatter
plot
were
found
to
be
0.52
and
1.04
respectively,
indicating
a
reasonable
correlation
between
the
data
pairs.

°
TTHM
formation
at
the
DS
Average
location
when
disinfecting
with
chloramine
in
the
distribution
system:
The
calibration
analysis
for
the
chloramine
condition
indicated
that
TTHM
formation
with
chloramine
=
0.30
×
TTHM
formation
with
free
chlorine.

6.
HAA5:

Similar
to
TTHM,
HAA5
was
calibrated
based
on
finished
water
and
RAA
results
for
chlorine
plants,
and
RAA
results
for
chloramine
plants.
Results
from
the
calibration
of
HAA5
formation
under
the
following
disinfection
scenarios
is
summarized
below:

°
Chlorine
in
treatment
plant
and
distribution
system
(
finished
water
location):
The
r2
of
the
scatter
plot
for
the
uncorrected
predicted
data
was
marginally
lower
than
that
in
the
case
of
TTHMs
(
i.
e.,
0.47).
However,
no
calibration
was
required
since
the
slope
of
the
best­
fit
line
forced
through
the
origin
(
for
the
uncorrected
predicted
data),
was
within
2
percent
of
unity.

°
Chlorine
in
treatment
plant
and
distribution
system
(
DS_
AVG
location):
The
r2
of
the
scatter
plot
for
the
uncorrected
predicted
data
was
marginally
lower
than
that
in
the
case
of
TTHMs
(
i.
e.,
0.37).
However,
no
calibration
was
required
since
the
slope
of
the
best­
fit
line,
forced
through
the
origin,
for
the
uncorrected
predicted
data,
was
nearly
unity.

°
Chloramine
in
distribution
system
(
DS_
AVG
location):
The
calibration
analysis
for
the
chloramine
condition
indicated
that
HAA5
formation
with
chloramine
=
0.35
×
HAA5
formation
with
free
chlorine.

The
middle
50
percent
of
the
observed
and
predicted
distributions
of
both
TTHM
and
HAA5
show
a
very
good
match.
However,
the
predicted
values
beyond
the
90th
percentile
are
significantly
higher
than
those
of
the
observed
values
(
approximately
25­
30
µ
g/
L
higher).
There
is
a
progressive
increase
in
disparity
at
the
tails
of
the
two
distributions
as
one
moves
from
pH,
to
TOC,
to
chlorine
residual,
and
finally
to
TTHM
or
HAA5.
Since
the
parameters
at
the
beginning
of
this
list
serve
as
inputs
to
the
algorithms
for
TTHM
and
HAA5
formation,
the
predictive
errors
propagate
from
the
pH
algorithm
to
the
DBP
algorithms.
Thus
the
probability
of
generating
outlier
predictions
increases
accordingly.
This
coupled
with
the
fact
that
there
are
large
uncertainties
in
the
distribution
system
residence
time
estimates,
results
in
the
DBP
predictions
exhibiting
the
maximum
spread
in
residuals
relative
to
the
other
parameters.

Summary
of
Uncertainties
Exhibit
A.
11
summarizes
the
uncertainties
in
SWAT
and
their
impact
on
costs
and
benefits.
The
uncertainties
are
grouped
into
four
areas:

°
Model
inputs
from
ICR
°
Model
algorithms
°
Decision
tree
°
Compliance
determinations
Note
that
the
direction
of
the
potential
bias
resulting
from
each
uncertainty
(
i.
e.,
whether
it
results
in
an
over­
or
under­
estimate)
is
the
same
for
both
costs
and
benefits
in
every
case.
None
of
the
uncertainties
creates
a
known
downward
bias
in
cost
and
benefit
estimates;
however,
some
are
expected
to
bias
both
cost
and
benefit
estimates
upward.
The
direction
of
the
impact
of
the
uncertainty
is
unknown
for
a
majority.

the

Verification
of
SWAT
Model
Results
This
section
provides
data
analyses
and
rationale
to
support
EPA's
conclusion
that
SWAT
is
an
adequate
tool
for
Stage
2
DBPR
benefit
and
cost
projections.
Validation
of
SWAT
is
limited
by
(
1)
the
absence
of
comparable
models
to
predict
DBP
formation
and
resulting
changes
in
DBP
formation
as
a
function
of
technology
changes,
and
(
2)
known
differences
between
the
specific
types
of
ICR
data
(
observed)
and
SWAT
data
(
predicted)
available
for
comparison.

There
are
two
main
analyses
in
this
section
that
are
used
to
support
the
use
of
SWAT
for
the
Stage
2
DBPR:

(
1)
Use
of
several
expert
polls
to
develop
technology
selection
predictions
for
the
Stage
1
DBPR
to
be
compared
to
SWAT­
predicted
technology
selections,
discussed
in

Section
A.

follows
with
conclusions.
It
is
important
to
note
that
ICR
observed
data
and
SWAT
predicted
data
are
expected
to
be
different,
as
explained
in
Section
A.
5.
Any
validation
of
SWAT
based
on
ICR
data
should
be
done
with
this
in
mind.

The
type
of
technologies
that
are
selected
by
non­
compliant

benefits
and
cost
estimates5.
To
validate
the
reasonableness
of
the
SWAT
technology
decision
tree
and
selection
methodology,
the
TWG
compared
two
independent
analyses
of
technology
forecasts
to
the
results
with
SWAT's
pre­
Stage
2
(
post­
Stage

DBPR
predictions.

The
two
independent
analyses
are
referred
to
as
the
"
Delphi
Poll"
and
the
"
Utility
Poll"
and
are
described
below.
A
discussion
of
results
follows.

ICR
Surface
Water
Expert
Poll
(
Delphi
Poll)

The
TWG
conducted
an
expert,
or
"
delphi"
poll
to
obtain
Stage
1
DBPR
impact
estimates,
based
on
technical
expertise.
Experts
were
provided
detailed
water
quality
and
treatment
process
characteristics
from
the
AUX1
database
for
all
ICR
plants
that
appeared
not
to
meet
the
MCLs
for
the
Stage
1
DBPR
(
based
on
the
ICR
data,
assuming
a
20
percent
safety
factor
for
compliance).
The
experts
then
reviewed
each
plant
to
determine
the
most
likely
technology
choice
to
meet
the
Stage
1
DBPR.
The
experts
were
also
asked
to
choose
the
least­
cost
technology
option.
If
an
expert
had
knowledge
about
a
specific
plant
that
would
lead
him
or
her
to
choose
a
technology
other
than
the
leastcost
the
expert
was
asked
to
identify
that
technology
and
the
reasons
for
the
choice.

ICR
Surface

Industry
Poll
(
Utility

The
industry
poll
was
developed
by
the
AWWA
and
served
a
similar
role
as
the
expert
poll.
It
compared
SWAT
results
to
the
Stage
1
DBPR
impacts
anticipated
by
industry
representatives.
In
this
process,
AWWA
surveyed
ICR
systems
and
asked
them
to
identify
the
technology
they
were
planning
to
implement
in
response
to
the
Stage
1
DBPR.
The
summarized
results
were
presented
to
the
M­
DBP
FACA
and
compared
with
the
other
predictions
(
USEPA
2000p)

Results
Exhibit

compares
the
technology

forecasts
predicted
by
SWAT,
the
Delphi
Poll
(
both
expected
and
least­

results),
and
the
Utility
Poll.
In
general,
the
distributions
of
Post­
Stage
1
technologies­
in­
place
predicted
by
the
polls
and
SWAT
are
in
good
agreement
with
each
other.
Relative
to
the
two
polls,
SWAT
does
not
significantly
over­
predict
or
under­
predict
the
expected
prevalence
of
any
technology
following
the
implementation
of
the
Stage
1
rule.
Based
on
these
comparisons,
the
FACA
determined
that
SWAT
was
sufficiently
reliable
to
also
serve
as
the
basis
for
making
Stage
2
technology
selection
forecasts
and
relied
upon
SWAT
outputs
to
compare
and
evaluate
regulatory
options
during
it's
deliberations.

of
quarterly

and
the

is
calculated
as
the
mean
of
the
residence
times
for
DSE,

July

In
addition
to
the
graphical
representation,
Exhibit
A.
21
provides
data
calculated
from
the
plots
that
can
be
used
to
assess
the
predictive
capability
of
SWAT
as
compared
to
ICR
observed
data.
Three
parameters
were
determined
to
be
of
interest
for
this
purpose:

1)
The
percent
of
plants
that
have
residuals
(
i.
e.,
SWAT
predicted
value
minus
the
ICR
observed
value)
that
are
within
±
20
:
g/
L.

2)
The
average
of
the
residuals
(
i.
e.,
SWAT
predicted
value
minus
the
ICR
observed
value)
for
all
plants.

3)
The
number
of
plants
in
Region
1
(
SWAT
predicts
compliance
change
but
ICR
does
not)
compared
to
the
number
of
plants
in
Region
IV
(
ICR
predicts
compliance
change
but
SWAT
does
not)

Observations
Results
for
the
RAA
calculation
show
that
nearly
60
percent
of
TTHM
residuals
(
residual
=
SWAT
minus
ICR
value)
and
approximately
65
percent
of
HAA5
residuals
are
within
±
20
:
g/
L.
Results
are
similar
for
the
single
highest
analyses.
Results
for
the
LRAA
calculation
show
that
a
smaller
percentage
of
residuals
(
41
and
47
percent
for
TTHM
and
HAA5,
respectively)
are
within
±
20
:
g/
L.
This
lower
percentage
could
be
due
to
the
fact
that
SWAT
LRAA
is
based
on
the
yearly
average
at
the
DS
Maximum
location,
whereas
the
ICR
LRAA
is
based
on
the
maximum
of
the
LRAA's
taken
at
leach
distribution
system
location
(
DSE,
AVG1,
AVG2,
and
DSMaximum).
Chapter
3
of
this
EA
explains
how
the
maximum
LRAA
from
the
ICR
occurs
at
the
DS
Maximum
only
about
50
percent
of
the
time.

The
residual
plots
and
the
calculated
average
of
all
residuals
(
shown
in
Exhibit
A.
21)
demonstrate
that
the
sum
of
all
positive
residuals
(
where
SWAT
predicts
higher
values
than
ICR)
and
the
sum
of
all
negative
residuals
(
where
SWAT
predicts
lower
values
than
the
ICR)
are
within
5
:
g/
L
of
each
other.
In
other
words:

Sum
of
All
Positive
Residuals
+
Sum
of
Negative
Residuals
-
0
­
5
:
g/
L
For
the
LRAA
and
single
highest
calculations,
the
total
positive
and
negative
residuals
are
even
closer
 
within
2
:
g/
L
in
most
cases.
This
indicates
that
the
national
average
TTHM
and
HAA5
concentrations
predicted
by
SWAT
for
all
large
surface
water
plants
is
very
similar
to
the
national
average
TTHM
and
HAA5
concentrations
measured
for
all
large
surface
water
plants
during
the
ICR.

The
SWAT
vs.
ICR
plots
illustrate
differences
in
compliance
forecasts
using
the
predicted
and
observed
data
sets.
As
described
in
Exhibit
A.
14,
the
plants
in
Regions
I
and
IV
are
where
SWAT
and

data
produce
different

results.

A­

July
2003
It
can
be
deduced
from
these
results
that
SWAT
predicts
Stage
1
DBPR
compliance
changes
for
10
percent
more
plants
([
46­
20]/
273)
than
ICR
based
on
the
TTHM
MCL.
HAA5
results
are
similar
 
37
plants
are
predicted
by
SWAT
but
not
by
ICR
to
change
technology
(
Region
I);
however
17
plants
are
predicted
by
ICR
but
not
SWAT
to
change
technology
(
Region
IV).
Results
show
that
SWAT
predicts
compliance
changes
for
approximately
7
percent
more
plants
([
37­
17]/
273)
than
ICR
based
on
the
HAA5
MCL
It
is
important
to
keep
in
mind
that
comparisons
of
ICR­
observed
and
SWAT­
predicted
data
represent
Pre­
Stage
1
conditions.
Cost
and
benefit
estimates
in
this
EA
are
based
on
the
incremental
impact
of
the
Stage
2
DBPR
after
systems
are
in
compliance
with
the
Stage
1
DBPR.

A.
7.3
Conclusions
Potential
errors
in
SWAT
DBP
predictions
can
affect
both
(
1)
the
estimated
reduction
in
DBP
concentration
due
to
the
Stage
2
DBPR
(
benefits),
and
(
2)
the
number
of
plants
changing
technology
and
which
technologies
these
plants
select
to
meet
Stage
2
DBPR
requirements
(
costs).
The
impact
of
potential
errors
in
SWAT
on
the
Stage
2
DBPR
cost
and
benefit
estimates
are
difficult
to
assess
because
of
the
nature
of
the
compliance
forecast
methodology.
The
four
general
steps
in
the
compliance
forecast
methodology
are
provided
below
(
see
section
6.4.2
for
a
full
discussion
of
the
compliance
forecast
generation).

°
Step
1:
Model
a
pre­
Stage
1
baseline
scenario
(
SWAT
"
initial
plant"
run)

°
Step
2:
Model
technology
selection
to
meet
Stage
1
DBPR
requirements
from
pre­
Stage
1
baseline
conditions.
Estimate
post­
Stage
1
average
TTHM
and
HAA5
concentrations
°
Step
3:
Model
technology
selection
to
meet
Stage
2
DBPR
requirements
from
pre­
Stage
1
baseline
conditions.
Estimate
Post­
Stage
2
average
TTHM
and
HAA5
concentrations.

°
Step
4:
Subtract
technology
selection
results
and
average
TTHM/
HAA5
concentrations
in
Step
2
from
Step
3
results
to
obtain
the
incremental
impacts
for
the
Stage
2
DBPR
Potential
error
in
DBP
predictions
can
be
evaluated
by
looking
at
plants
in
different
regions
of
the
SWAT
vs.
ICR
plots.
For
plants
that
do
not
make
treatment
changes
for
Stage
1
or
Stage
2
(
Regions
V
and
VI),
errors
in
the
predicted
DBP
concentrations
will
subtract
out
during
Step
4
of
the
compliance
forecast
methodology.
For
plants
that
are
predicted
to
make
changes
for
Stage
1
or
Stage
2
(
Regions
II
and
III),
errors
in
the
magnitude
of
DBP
predictions
will
also
cancel
out
during
Step
4.
For
these
plants,
the
errors
in
DBP
prediction
for
post­
Stage
2
conditions
represent
the
error
in
the
change
in
DBP
concentrations
caused
by
changes
in
technology.

The
largest
area
for
error
is
for
those
plants
predicted
to
make
a
technology
change
for
Stage
1
or
Stage
2
where
the
observed
data
shows
they
do
not
need
to
change,
or
vice
versa
(
Regions
I
and
IV).
For
the
TTHM
RAA
compliance
calculation
(
Stage
1),
approximately
17
percent
of
plants
fall
in
Region
I,
which
7
percent
of
plants
fall
in
Region
IV.
For
the
HAA5
RAA
compliance
calculation,
the
results
are
similar
 
approximately
14
percent
of
plants
fall
in
Region
I,
while
6
percent
of
plants
fall
in
Region
IV.
These
results
indicate
that
there
could
be
an
over­
prediction
in
the
SWAT
compliance
forecast
for
the
Stage
1
DBPR
compared
to
ICR
observed
data.
Economic
Analysis
for
the
Stage
2
DBPR
Proposal
A­
41
July
2003
The
results
for
Stage
1
indicate
that
there
may
be
a
similar
"
over­
prediction"
in
the
compliance
forecast
(
and
resulting
decrease
in
TTHM/
HAA5
occurrence)
for
the
Stage
2
DBPR.
Because
of
the
nature
of
the
ICR
data
set
(
which
is
limited
to
pre­
Stage
1
conditions),
it
is
not
possible
to
use
it
directly
to
estimate
changes
between
Stage
1
and
Stage
2
and,
therefore,
comparisons
with
SWAT
predictions
for
Stage
1
to
Stage
2
are
not
possible.
However,
it
would
be
reasonable
to
expect
that
such
a
comparison
would
show
that
SWAT
would
predict
more
technology
changes
than
ICR
between
Stage
1
and
Stage
2.
Because
the
changes
in
regulatory
requirements
from
the
Stage
1
DBPR
to
the
Stage
2
DBPR
are
smaller
in
scope
than
the
changes
in
regulatory
requirements
from
the
1979
TTHM
Rule
and
the
Stage
1
DBPR,
it
is
mostly
likely
that
the
magnitude
of
the
SWAT
over­
prediction
from
Stage
1
to
Stage
2
would
be
lower
than
the
magnitude
of
the
SWAT
over­
prediction
from
pre­
Stage
1
to
Stage
1.

As
shown
in
the
"
observations"
in
section
A.
7.2,
there
is
good
agreement
in
national
average
TTHM
and
HAA5
data
for
all
large
surface
water
plants
as
predicted
by
SWAT
and
as
reported
during
the
ICR.
Also,
the
SWAT
Stage
1
DBPR
technology
selection
was
validated
by
two
independent
groups
during
the
M­
DBP
FACA
process
(
see
section
A.
7.1).
While
there
is
a
potential
over­
prediction
in
compliance
changes
(
resulting
in
both
increased
costs
and
benefits)
based
on
comparison
of
pre­
Stage
1
SWAT­
predicted
and
ICR
observed
data,
any
over­
prediction
between
Stage
1
and
Stage
2
is
expected
to
be
comparatively
small.
For
these
reasons,
EPA
has
concluded
that
SWAT
is
sufficiently
reliable
to
predict
the
likely
changes
in
technology
use
and
in
byproduct
formation
to
serve
as
the
basis
for
comparing
the
Stage
2
DBPR
options
in
this
EA.
This
conclusion
is
consistent
with
recommendations
from
the
M­
DBP
FACA.

Part

Compliance
Forecasts
To
estimate
the
rule's
total
benefits
and
costs,
accurate
forecasting
of
the
compliance
of
surface
water
systems
with
the
Stage
2
DBPR
is
critical.
The
compliance
forecasts
for
large
surface
water
systems
were
derived
from
Information
Collection
Rule
(
ICR)
data
using
SWAT.
Comprehensive
data
on
operational
parameters
and
water
quality,
similar
to
those
gathered
for
large
systems
under
the
ICR,
were
not
available
for
medium
and
small
systems.
Because
water
quality
and
operational
capabilities
of
medium
and
small
systems
were
anticipated
to
differ
from
those
of
large
systems,
a
detailed
evaluation
was
performed
to
accurately
estimate
impacts
of
the
Stage
2
DBPR
on
medium
and
small
systems.
A
Non­
ICR
Subgroup
of
the
TWG
for
the
Microbial­
Disinfection
Byproducts
Advisory
Committee
(
the
Subgroup)
was
charged
with
understanding
the
nature
of
medium
and
small
systems
and
developing
methodologies
for
further
analysis.
Detailed
descriptions
of
the
methodologies
used
in
developing
compliance
forecasts
for
each
system
size
category
are
provided
in
the
latter
sections
of
this
appendix.

SWAT­
based
Compliance
Forecasts
for
Large
Surface
Water
Systems
The
compliance
forecasts
for
large
surface
water
systems
were
derived
primarily
using
SWAT.
The
SWAT
program
can
also
be
run
in
a
mode
that
evaluates
all
possible
technology
choices
for
each
plant
and
the
resulting
DBP
predictions,
called
the
SWAT
Screen
Series.
The
SWAT
Screen
Series
provides
three
primary
outputs:
DBP
Exposures,
Ending
Technologies,
and
Technology
Selection,
consolidated
together
by
the
Screening
Database.
DBP
Exposures
provides
the
predicted
values
of
TTHM,
HAA5,
chlorite,
and
bromate
for
each
rule
option
being
examined.
Ending
Technologies
predicts
the
percentages
of
all
plants
using
each
type
of
treatment
after
the
rule
option
is
implemented.

Technology
Selection
predicts
the
distribution
of
treatment
only
for
those

predicted
to

or

advanced
technology.

SWAT
cannot
take
compliance
with
Stage
1
DBPR
into
account
when
predicting
compliance
forecasts
for
Stage
2.
Hence,
technology
shifts
from
Stage
1
to
Stage
2
are
estimated
by
subtracting
the
technology
shift
from
pre­
Stage
1
to
Stage
1
from
the
technology
shift
from
pre­
Stage
1
to
Stage
2.

Adjustments
for
the
Stage
1
DBPR
As
summarized
in
chapter
6,
the
compliance
forecasts
for
the
Stage
2
DBPR
regulatory
alternatives
were
developed
by
estimating
the
Stage
1
and
the
Stage
2
DBPR
compliance
forecasts
from
the
pre­
Stage
1
baseline,
and
subtracting
the
two
to
produce
the
incremental
treatment
changes
for
the
Stage
2
DBPR.
Different
technologies,
however,
were
assumed
to
be
available
to
meet
the
regulatory
requirements
of
the
Stage
1
and
Stage
2
DBPRs.
UV
was
not
a
proven
disinfectant
for
Cryptosporidium,
Giardia,
or
viruses
at
the
time
of
the
ICR
or
when
plants
were
expected
to
make
treatment
decisions
to
meet
Stage
1
DBPR
requirements.
EPA
now
considers
UV
a
viable
alternative
disinfectant
to
chlorine
to
meet
Stage
2
DBPR
regulatory
alternatives.

Because
UV
is
considered
an
available
technology
for
the
Stage
2
DBPR,
some
plants
are
predicted
to
use
UV
instead
of
more
expensive
technologies
such
as
ozone,
MF/
UF,
or
granular
activated
carbon
(
GAC).
If
the
compliance
forecasts
for
the
Stage
1
and
Stage
2
DBPRs
were
used
independently,
more
expensive
technologies
installed
to
meet
Stage
1
would
effectively
be
removed
from
the
plant
to
install
less
expensive
technologies
UV
under
Stage
2.
In
reality,
systems
that
added
technology
for
Stage
1
may
not
need
to
add
another
technology
for
Stage
2.

SWAT
is
not
able
to
take
compliance
with
the
Stage
1
DBPR
into
account
when
predicting
compliance
forecasts
for
the
Stage
2
DBPR.
To
account
for
the
effect
of
less
expensive
technologies
becoming
available
to
meet
the
Stage
2
DBPR,
SWAT
modeled
the
Stage
2
DBPR
regulatory
alternatives
with
and
without
UV
as
an
available
technology
and
made
the
following
adjustments.

°
Start
with
SWAT
predictions
for
treatment
technology
changes
for
both
the
Stage
1
DBPR
and
Stage
2
DBPR
options
first
assuming
that
UV
is
an
available
technology
for
both
rules,
and
then
assuming
that
it
is
not
available
for
either
rule.

°
Use
the
Stage
1
DBPR
estimates
of
ozone,
MF/
UF,
and
GAC10
usage
if
they
are
higher
than
the
Stage
2
estimates
that
include
UV
as
a
technology,
since
such
systems
are
predicted
to
use
these
technologies
for
Stage
1
and
will
not
remove
them
to
install
UV.

°
Decrease
the
percentage
of
plants
using
UV
accordingly.

°
Use
the
percentage
of
plants
predicted
to
add
chloramine
from
the
Stage
2
DBPR
without
UV
option.
This
percentage
decreases
when
UV
is
an
available
technology.
Because
not
as
many
plants
are
believed
to
use
UV,
the
estimate
from
the
Stage
2
DBPR
without
UV
option
is
taken
for
the
adjusted
option.

After
a
detailed
review
of
available
data,
TWG
Small/
Medium
Systems
Subgroup
concluded
that
the
influent
water
quality,
treatment
characterization,
and
DBP
occurrence
of
medium
surface
water
plants
are
similar
to
large
surface
water
plants.
This
section
describes
and
examines
the
data
that
support
this
conclusion.

The
Water
Utility
Database
(
WATER:\
STATS
[
AWWA
2000]),
developed
by
the
American
Water
Works
Association
(
AWWA),
was
used
in
this
analysis.
The
most
recent
WATER:\
STATS
data
are
from
a
1996
survey
of
approximately
900
utilities.
This
database
includes
information
on
influent
water
quality,
treatment,
and
the
occurrence
of
DBPs
in
finished
water
for
all
system
sizes.
The
Subgroup
assumed
that
large
systems
in
WATER:\
STATS
were
equivalent
to
ICR
systems
and
plants.
To
maintain
consistency,
therefore,
only
WATER:\
STATS
data
were
used
to
compare
large
and
medium
surface
water
systems.

Exhibit
A.

compares
source

large
surface
water
systems.
Further
information
is
provided
in
the
Stage
2
DBPR
Occurrence
Document
(
USEPA
2003l).
Given
the
similarities
in
the
distribution
of
large
and
medium
systems
using
each
type
of
surface
water,
the
Subgroup
expected
to
find
only
minor
differences
in
source
water
quality.

Economic

DBPR
Proposal
A­
60
July
2003
Because
of
the
similarities
between
large
and
medium
surface
water
systems,
the
Subgroup
assumed
that
ICR
data
on
DBP
occurrence
and
the
results
of
the
SWAT
analysis
were
also
applicable
to
medium
surface
water
systems.
Thus,
the
Subgroup
assumed
that
medium
surface
water
systems
used
technologies
in
the
same
proportion
as
large
surface
water
systems.

For
this
proportional
allocation
to
be
valid,
some
similarity
must
exist
between
the
national
geographical
distribution
of
ICR
surface
water
systems
and
that
of
medium
surface
water
systems.
The
Subgroup
compared
the
distribution
of
ICR
surface
water
systems
by
State
to
the
distribution
of
medium
surface
water
systems
by
State
(
based
on
the
Baseline
Handbook
[
USEPA
2001h]).
This
effort
established
that
there
is
not
a
significant
difference
in
overall
geographic
distribution
(
as
shown
in
Exhibit
A.
30),
although
there
is
some
variation
in
the
distribution
of
systems
at
different
size
categories.

To
ensure
that
the
distribution
assumptions
did
not
mask
differences
that
may
affect
DBP
formation,
additional
analyses
were
performed.
In
particular,
the
distribution
of
systems
with
high
levels
of
DBP
precursors
(
TOC
in
Florida,
bromide
in
Texas;
based
on
State
data
and
ICR
data
analysis)
within
certain
States
was
examined.
No
significant
difference
was
found
between
the
percentages
of
medium
and
large
systems
with
high
precursor
levels.
The
Subgroup
concluded
that
SWAT
predictions
of
occurrence
for
large
systems
could
be
directly
applied
to
the
universe
of
medium
surface
water
plants.

SWAT

Forecasts
for
Small

Water
Systems
Small
surface
water
systems
differ
in
many
ways
from
medium
and
large
surface
water
systems.
Small
systems
are
exempt
from
the
1979
Total
Trihalomethane
Rule,
which
set
the
TTHM
MCL
at
100
µ
g/
L.
Source
water
quality
is
somewhat
better
in
small
systems
than
in
larger
systems,
as
demonstrated
by
the
ICR
Supplemental
and
National
Rural
Water
Association
(
NRWA)
Survey
data,
discussed
below,
and
the
Stage
2
DBPR
Occurrence
and
Exposure
Assessment
(
USEPA
2003l).
Unit
cost
estimates
for
new
technologies
are
higher
in
small
systems
than
larger
systems,
which
may
drive
small
systems
to
take
different
treatment
approaches.
In
addition,
some
technologies
predicted
for
use
in
large
and
medium
systems
may
not
be
feasible
in
small
systems.
Due
to
these
considerations,
the
Technical
Workgroup
used
an
expert
review
process
to
estimate
the
impact
of
the
proposed
Stage
2
DBPR
options
on
small
systems.
The
method,
or
the
Delphi
Poll
process,
consisted
of
a
group
of
identified
experts
who
provided
their
best
professional
judgement
to
identify
likely
technologies
for
affected
plants.
The
expert
opinions
were
consolidated
for
a
best
estimate
of
the
technology
selection
response
of
compliance
affected
systems.
This
provided
a
compliance
forecast
for
a
given
regulatory
option.

The
participating
experts
included
members
of
the
NRWA
(
a
federation
of
45
State
rural
water
associations,
representing
over
19,000
water
and
wastewater
utilities),
EPA
staff,
and
consulting
engineers
with
many
years
of
experience
in
small
surface
water
systems.
The
review
process
for
small
surface
water
systems
integrated
technical
analyses
of
source
water
characteristics
and
experts'
predictions
of
anticipated
changes
in
technologies
and
DBP
formation.
The
experts'
responses
were
then
aggregated
for
further
analysis.

A.
10.1
Methodology
For
the
expert
review
process,
small
surface
water
systems
were
subdivided
into
three
size
categories:
systems
serving
100
or
fewer
people,
systems
serving
101
to
1,000
people,
and
systems
serving
between
1,001
and
10,000
people.
The
Subgroup
expected
systems
in
each
category
to
make
different
treatment
choices.

The
following
sections
detail
the
results
of
the
Subgroup's
deliberation
of
specific
technologies.
The
flowchart
describing
the
analytical
process
is
shown
in
Exhibit
A.
32.

Systems
Serving
1,001
to
10,000
People
A
review
of
ICR
Supplemental
Survey
and
NRWA
Survey
data
indicated
that
source
water
quality
at
small
systems
was
better
than
that
at
large
systems.
NRWA
Survey
results
showed
slightly
higher
TOC
concentrations;
however,
NRWA
results
may
be
biased,
as
discussed
in
the
Occurrence
document
(
USEPA
2003l).
Based
on
Supplemental
Survey
data
shown
in
Exhibit
A.
31,
the
Subgroup
predicted
that
a
smaller
proportion
of
small
systems
would
change
to
advanced
technologies
as
a
result
of
the
Stage
1
and
Stage
2
DBPRs
than
the
proportion
of
large
systems
predicted
by
SWAT.

The
Subgroup
adjusted
the
percentage
of
small
systems
using
conventional
or
nonconventional
treatment
(
i.
e.,
not
switching
to
advanced
treatment)
in
the
following
manner:

output.

SWAT
predicted
that
the
percentage
of
large
systems
using
conventional
or
nonconventional
treatment
would
exceed
65
percent,
so
the
percentage
for
small
systems
was
increased
to
75.
To
accomplish
this,
the
Subgroup
removed
systems
from
other
treatment
categories,
including
chlorine
dioxide,
UV,
and
ozone.
The
Subgroup
assumed
that
the
conventional
treatment
category
included
some
systems
modifying
treatment
by
increasing
coagulant
dose,
installing
a
pre­
sedimentation
basin,
or
moving
the
point
of
chlorination.
While
these
activities
pose
a
smaller
impact
to
large
systems
than
implementing
an
advanced
technology
does,
some
of
these
modifications
(
e.
g.,
installing
a
pre­
sedimentation
basin)
could
constitute
a
substantial
burden
for
a
few
small
systems.
However,
the
Subgroup
was
of
the
opinion
that
on
a
national
scale
the
effects
would
not
be
significant,
and
hence
did
not
account
for
it.

that

and
increased
the
number
of
systems
predicted
to
change
to
advanced
technologies.

Because
SWAT
predictions
are
based
on
large
systems,
they
do
not
account
for
small
systems
known
to
be
using
microfiltration
or
ultrafiltration
before
the
Stage
1
DBPR
was
implemented
(
no
large
systems
were
using
these
technologies
during
the
ICR
period).
According
to
the
NRWA
Survey,
microfiltration
and
ultrafiltration
were
used
by
3.6
percent
of
small
systems
before
the
Stage
1
DBPR
went
into
effect.
As
a
result,
the
experts
added
3.6
percent
to
the
percentage
of
small
systems
predicted
to
be
using
microfiltration
and
ultrafiltration
after
the
Stage
1
and
Stage
2
DBPRs.
These
extra
systems
were
subtracted
from
the
systems
predicted
to
use
chlorine
dioxide,
ozone,
and
UV,
as
predicted
by
SWAT.

The
SWAT
model
includes
four
options
for
systems
using
GAC:

°
GAC10
(
10­
minute
empty
bed
contact
time)

°
GAC10
plus
advanced
disinfectants
°
GAC20
(
20­
minute
empty
bed
contact
time)

°
GAC20
plus
advanced
disinfectants
Costs
for
GAC
systems
include
frequent
replacement
or
regeneration
of
the
carbon
media.
The
Subgroup
believed
that
surface
water
systems
serving
more
than
1,000
people
would
choose
to
replace
rather
than
regenerate
their
GAC
media.
Because
unit
costs
for
GAC20
with
replacement
are
lower
than
unit
costs
for
GAC10
with
regeneration
of
the
media
(
for
small
systems),
the
Subgroup
assumed
that
the
systems
using
GAC10
or
GAC10
plus
advanced
oxidants,
based
on
the
large
system
prediction,
would
instead
use
GAC20
or
GAC20
plus
advanced
disinfectants,
respectively.

Systems
Serving
101
to
1,000
People
For
systems
serving
101
to
1,000
people,
the
starting
point
for
technology
selection
was
the
technology
distribution
predicted
for
systems
serving
1,001
to
10,000
people.
These
predictions
were
further
modified
to
account
for
the
difficulties
systems
of
this
size
might
have
with
disinfectants
such
as
ozone,
chlorine
dioxide,
and
chloramines.
Predictions
for
systems
using
GAC20
were
adjusted
as
well.

In
general,
the
Subgroup
established
that
many
small
systems
would
probably
not
use
chlorine
dioxide,
because
it
is
difficult
to
handle
and
must
be
generated
on­
site.
The
application
of
chlorine
dioxide
also
requires
daily
testing
for
chlorite,
a
regulated
DBP.
The
effort
or
expertise
required
for
this
testing
may
be
beyond
the
capacity
of
many
small
systems.
Therefore,
the
Subgroup
constrained
chlorine
dioxide
use
in
the
101­
1,000
size
category
to
half
that
of
the
1,001
to
10,000
category,
allocating
the
rest
to
UV,
ozone,
and
MF/
UF
in
proportion
to
the
existing
numbers
for
these
technologies.

The
preceding
constraints
on
the
technologies
available
to
small
systems
necessitated
predicting
the
technology
to
which
each
small
system
will
switch.
The
only
difference
between
the
SWAT
Decision
Tree
and
the
one
used
for
small
surface
water
systems
is
that
GAC10
is
not
an
option
for
the
small
surface
water
systems.
The
Subgroup
also
assumed
that
systems
predicted
to
modify
their
primary
treatment
would
continue
to
use
the
same
residual
disinfectant.
Economic
Analysis
for
the
Stage
2
DBPR
Proposal
A­
64
July
2003
The
Subgroup
next
adjusted
the
compliance
forecast
to
account
for
a
small
portion
of
smaller
systems
that
may
not
be
able
to
apply
GAC20
technologies.
The
Subgroup
subtracted
10
percent
from
the
percentage
of
systems
predicted
to
use
GAC20.
The
systems
removed
from
GAC20
were
then
added
to
NF,
the
next
available
technology
on
the
decision
tree.
NF
is
defined
as
microfiltration
followed
by
nanofiltration.

Chloramine
use
may
be
difficult
for
some
small
systems,
especially
if
an
operator
is
not
always
present.
Chloramine
use
was
adjusted
in
a
two­
step
process.
First,
the
percentage
of
systems
predicted
to
use
chloramine
as
a
residual
disinfectant
was
reduced
to
90
percent
of
the
value
predicted
for
systems
serving
1,001
to
10,000
people.
These
systems
instead
were
predicted
to
use
chlorine
as
a
residual
disinfectant.
Second,
the
Subgroup
predicted
that
systems
using
chlorine
would
switch
to
different
primary
technologies.
This
reallocation
was
necessary
because
chlorine
contributes
more
to
DBP
formation
than
chloramine
does,
thereby
forcing
systems
to
use
a
higher
cost
technology
in
order
to
meet
the
DBP
standards
of
the
Stage
2
DBPR.

Systems
Serving
100
or
Fewer
People
For
systems
serving
100
or
fewer
people,
the
starting
point
for
technology
selection
was
the
technology
distribution
predicted
for
systems
serving
101
to
1,000
people.
These
predictions
were
modified
to
account
for
the
additional
difficulties
systems
of
this
size
might
have
with
disinfectants
such
as
ozone,
chlorine
dioxide,
and
chloramine.
Predictions
for
systems
using
GAC20
were
adjusted
as
well.

The
Subgroup
assumed
no
systems
in
this
size
category
would
use
chlorine
dioxide
or
ozone.
Consequently,
the
Subgroup
allocated
to
conventional
treatment
two­
thirds
of
the
systems
that
were
predicted
to
use
chlorine
dioxide
and
ozone.
The
remaining
one­
third
of
chlorine
dioxide
systems
were
allocated
to
UV,
MF/
UF,
GAC20,
GAC20
with
UV,
and
NF,
and
the
remaining
one­
third
of
ozone
systems
were
allocated
to
MF/
UF,
GAC20,
GAC20
with
UV,
and
NF,
all
in
proportion
to
existing
numbers
for
these
technologies.

As
with
systems
serving
101
to
1,000
people,
the
percentage
of
systems
predicted
to
use
GAC20
was
decreased
by
10.
The
systems
removed
from
GAC20
were
then
added
to
NF,
the
next
available
technology
on
the
decision
tree.

The
Subgroup
adjusted
chloramine
usage
using
the
same
process
as
it
did
for
systems
serving
101
to
1,000
people,
except
that
the
percentage
of
systems
predicted
to
use
chloramine
as
a
residual
disinfectant
was
reduced
to
75
percent,
rather
than
90
percent.

The
most
significant
effect
of
the
chloramine
constraint
was
that
systems
using
less
expensive
technologies
were
predicted
to
move
towards
more
expensive
technologies.
This
effectively
neutralizes
the
cost
savings
small
systems
might
have
achieved
through
better
source
water
quality.
A
review
of
the
compliance
forecasts
shows
that
when
the
Stage
1
DBPR
predictions
for
both
large
and
small
surface
water
systems
are
compared,
there
is
no
significant
difference
in
the
percentage
of
systems
using
advanced
technologies
to
comply
with
the
Stage
1
DBPR.
Small
systems
have
better
source
water
quality
than
large
systems
do,
but
this
is
outweighed
by
the
fact
that
they
must
install
more
expensive
technologies
to
comply
with
DBP
regulations
and
by
the
fact
that
large
systems
are
already
complying
with
the
1979
TTHM
Rule.

To

for
the
effect
of
less

technologies
becoming
available
to

the

DBPR
requirements
for
small
surface
water
systems,
the
following
adjustments
were
made
to
the
Stage

ending
technology
predictions
made
by
the
Delphi
subgroup:

°
Start
with
SWAT/
Delphi
subgroup

Stage
1
DBPR
and
Stage
2
DBPR
options
(
with
and
without
UV),
for
the
small
surface
water
systems.

°
First
check
the
Stage
2
small
surface
water
predictions
for
NF
(
i.
e.,
the
most
expensive
technology).
Use
the
Stage
1
DBPR
estimates
for
NF
usage
if
they
are
higher
than
the
Stage
2
NF
usage
estimates.
This
is
because
systems
predicted
to
use
NF
for
Stage
1
will
not
remove
them
to
shift
to
a
lower
technologies
based
on
the
actual
Stage
2
predictions.

°
Repeat
the
above
step
with
the
next
most
expensive
technology
(
i.
e.,
GAC20
&
UV
or
AO).
Continue
this
procedure
for
each
succeeding
technology,
moving
all
the
way
down
to
chlorine
dioxide.

Compliance
Forecasts
B.

Introduction
This
appendix
documents
the
derivation
of
the
compliance
forecasts
for
ground
water
plants
used
in
the
Economic
Analysis
(
EA)
for
the
Stage
2
Disinfectants
and
Disinfection
Byproducts
Rule
(
DBPR).
The
compliance
forecast
for
the
large
ground
water
plants
was
generated
using
the
Information
Collection
Rule
(
ICR)
Ground
Water
Delphi
process,
which
convened
a
group
of
ground
water
system
experts.
Medium
plants
were
evaluated
similarly
to
large
plants.
Compliance
forecasts
for
small
plants
were
developed
under
the
small
ground
water
system
expert
review
process.
The
following
sections
provide
the
methodology
for
developing
compliance
forecasts
for
all
ground
water
plants.

B.
2
Compliance
Forecast
for
Large
and
Medium
Ground
Water
Plants
Unlike
the
compliance
forecast
for
surface
water
plants
generated
by
the
Surface
Water
Analytical
Tool
(
SWAT),
the
forecast
for
ground
water
plants
in
large
and
medium
systems
(
those
serving
over
10,000
people)
was
developed
in
two
distinct
steps
described
below
(
and
summarized
in
Exhibit
B.
1).

°
Estimate
percent
non­
compliers:
First,
the
ICR
Ground
Water
Delphi
Group
used
ICR
data
to
evaluate
each
plant
for
compliance
under
various
regulatory
alternatives.
Because
a
majority
of
the
large
plants
predicted
to
be
out
of
compliance
were
located
in
Florida,
the
Environmental
Protection
Agency
(
EPA)
applied
a
"
Florida/
Non­
Florida"
stratification
to
the
results.

°
Apply
treatment
selection
forecasts
to
the
non­
compliers:
A
group
of
ground
water
system
experts
 
a
Delphi
group
 
predicted
technology
selection
for
each
non­
compliant
large
ground
water
plant.
These
plant­
level
analyses
were
aggregated
into
national­
level
compliance
treatment
forecasts,
which
were
then
applied
to
the
percent
noncomplying
for
the
medium
and
large
systems.

Section
B.
2.2
explains
the
rationale
for
using
ICR
Delphi
results
for

systems.

At
the
time
of
the
Delphi
process,
EPA
was
still
evaluating
a
vast
number
of
regulatory
alternatives
and
had
not
reached
agreement
from
the
Federal
Advisory
Committees
Act
(
FACA)
on
the
Preferred
Regulatory
Alternative.
Therefore,
the
Delphi
group
analyzed
four
"
bounding"
alternatives
to
address
the
variety
in
both
MCL
levels
(
80

for

The

A
total
of
130
large
ground
water
plants
were
evaluated
using
the
last
12
months
of
ICR
data.
Based
on
data
in
the
ICR
applicability
database,
there
is
a
higher
total
number
of
ground
water
plants
in
large
systems
(
see
Chapter
4
for
the
baseline
number
of
large
plants
used
in
this
analysis).
Some
of
the
plants
within
a
system
may
be
medium
or
small
plants
(
serving
fewer
than
100,000
people),
which
is
why
they
were
not
included
in
the
ICR.
The
EA
used
the
total
plant
estimate
from
the
ICR
applicability
database
for
costing.
This
accounts
for
medium
and
small
plants
in
large
systems
by
adjusting
the
flow
per
plant.

ICR
Data
ICR
data
(
USEPA
2000h)
were
evaluated
to
estimate
the
number
of
plants
that
would
currently
exceed
MCL
requirements
of
the
Stage
1
DBPR
and
each
of
the
Stage
2
DBPR
regulatory
alternatives.
1
Plants
were
initially
classified
as
non­
complying
if
ICR
data
showed
that
they
exceeded
the
MCLs,
taking
into
account
a
20
percent
safety
factor.
For
example,
the
Preferred
Alternative
for
the
Stage
2
DBPR
is
80
µ
g/
L
measured
as
an
LRAA
for
TTHM
and
60
µ
g/
L
measured
as
an
LRAA
for
HAA5.
Compliance,
therefore,
is
evaluated
for
64
µ
g/
L
for
TTHM
and
48
µ
g/
L
for
HAA5,
both
measured
as
LRAAs.

EPA
also
evaluated
plant
and
system
characteristics
and
determined
that,
in
some
cases,
distributed
water
from
ground
water
plants
was
being
blended
with
water
from
surface
water
plants
in
the
distribution
system.
This
may
have
resulted
in
higher
TTHM
and
HAA5
concentrations
than
would
normally
be
associated
with
an
individual
ground
water
plant.

these

assessment,
the
percent
of
non­

ground

may
be
overstated.
Therefore,
ground
water
plants
that
had
a
surface
water
plant
with
the
same
public
water
system
ID
number
were
removed
from
the
set
of
non­
compliers
for
all
regulatory
alternatives
(
i.
e.,
the
surface
water
plant
would
most
likely
make
modifications
rather
than
the
ground
water
plant).

For
regulatory
alternatives
based
on
LRAA
and
RAA
calculations,
EPA
further
reviewed
ICR
data
to
evaluate
the
variance
in
individual
distribution
system
measurements.
Influent
water
quality
does
not
typically
fluctuate
in
ground
water
systems
as
much
as
it
can
in
surface
water
systems.
Distribution
system
TTHM
and
HAA5
concentrations
may
not
vary
much,
and,
thus,
some
ground
water
systems
may
be
able
to
continuously
meet
an
LRAA
and
RAA
standard
above
the
20
percent
safety
factor
(
i.
e.,
ground
water
systems
may
not
need
as
large
a
safety
factor).
EPA
evaluated
all
systems
predicted
to
be
above
the
LRAA
and
RAA
limits
with
the
20
percent
safety
factor
against
the
single
highest
(
SH)
value
reported
in
the
ICR.
If
the
annual
average
concentration
(
measured
as
either
LRAA
or
RAA)
and
the
SH
value
were
below
the
true
regulatory
limit
(
without
the
safety
factor),
EPA
assumed
that
it
was
unlikely
that
the
ground
water
plant
would
add
treatment
to
comply
with
the
rule.
These
plants
were
removed
from
the
set
of
non­
complying
plants.

EPA
evaluated
the
regional
characteristics
of
those
plants
exceeding
MCLs
for
each
alternative.
Large
ground
water
plants
in
Florida
comprise
the
majority
of
large
ground
water
plants
predicted
to
be
out
of
compliance
with
all
regulatory
scenarios
because
of
the
typically
high
influent
total
organic
carbon
(
TOC)
concentrations
in
Florida
compared
to
other
areas
in
the
United
States.
(
see
Chapter
4
for
a
discussion
of
regional
impacts).
To
avoid
inappropriately
extrapolating
national
estimates
of
noncompliance
from
the
heavily
Florida­
weighted
results,
EPA
evaluated
Florida
and
Non­
Florida
plants
separately
and
then
aggregated
the
results
together
to
produce
national
estimates.
Below
is
a
step­
bystep
explanation
of
how
the
percent
of
non­
compliers
was
calculated
using
the
Florida/
Non­
Florida
stratification.

Step
1:
Determine
the

number
of

Non­

plants
Exhibit

shows
baseline
data,
presented

for

and
Non­

The
total
number
of
Florida
ground

systems
was
derived
from
the
Baseline
Handbook.
EPA
assumes
that
all
Florida
ground
water
systems
disinfect
(
USEPA
1996a).
Also,
surface
water
systems
in
Florida
with
the
majority
of
their
flow
from
ground

were
moved

(
see
Chapter
3
for
an
explanation
of
how
EPA
altered
system
inventories
so
that
they
are
classified
by
primary
water
source).
Systems
were
converted
to
plants
using
plant
per
system
ratios
presented
in
Chapter
3,
with
the
exception
of
the
systems
serving
100,000
to
1
million
people.
The
ICR
Applicability
database
was
used
to
determine
the
relative
plants
per
system
ratio
for
Florida/
Non­
Florida
systems.
The
analysis
showed
that
Florida
systems
had
a
lower
plant
per
system
ratio
than
Non­
Florida
systems.
The
national
plant
per
system
number
was
weighted
to
reflect
this
difference.

Step
2
:
Estimate
the
percent
of
non­
complying
plants
in
Florida
The
percent
of
non­
complying
plants
in
Florida
was
based
on
an
evaluation
of
ICR
ground
water
plant
data
for
non­
surface
water
influenced
plants
(
as
previously
noted,
ground
water
distribution
systems
were
determined
to
be
potentially
under
the
influence
of
surface
water
if
systems
included
a
surface
water
plant).
The
percent
not
complying
is
applied
to
the
baseline
of
both
large
and
medium
plants.

Step
3:
Estimate
the
percent
of
non­
complying
plants
outside
of
Florida
The
percent
of
non­
complying,
Non­
Florida
plants
was
based
on
an
evaluation
of
ICR
ground
water
plant
data
for
non­
surface
water
influenced
plants.
The
same
methodology
was
used,
as
described
in
Step
2,
to
obtain
the
percent
non­
compliers
for
Non­
Florida
plants.
This
percentage
was
applied
to
both
medium
and
large
plants.

Step
4:
Estimate
the
total
national
percent
of
non­
complying
plants
For
each
medium
and
large
size
category,
the
total
number
of
non­
complying
plants
was
estimated
by
multiplying
the
percentages
in
Steps
2
and
3
by
the
baseline
numbers
from
Exhibit
B.
6
of
Florida
and
Non­
Florida
plants,
respectively.
The
number
of
non­
complying
Florida
and
Non­
Florida
plants
were
then
summed
and
divided
by
the
total
number
of
plants
(
Florida
plus
Non­
Florida).
By
using
this
method,
EPA
was
able
to
estimate
a
more
accurate
national
percentage
of
plants
out
of
compliance
with
the
Stage
2
DBPR.

Technology
Selection
Original
"
Bounding"
Alternatives
The
Delphi
group
used
a
multi­
step
process
to
develop
the
compliance
forecasts
for
those
large
ground
water
plants
out
of
compliance
with
the
four
original
regulatory
alternatives.

Drawing
from
data
collected
under
the
ICR,
Delphi
group
participants
were
given
details
(
such
as
plant
type,
residual
disinfectant,
and
water
quality)
about
the
ground
water
plants
unable
to
meet
the
MCLs
of
each
alternative.
Delphi
participants
selected
a
treatment
technology
from
a
list
of
16
technologies
and
a
residual
disinfectant
(
chlorine
or
chloramines)
for
each
plant
and
rated
their
confidence
in
their
technology
selections.
Each
Delphi
participant
focused
on
different
information
to
select
the
technology
required
by
each
plant.
Some
participants
gave
greater
importance
to
water
quality
aspects,
while
others
emphasized
design
issues.
In
general,
the
Delphi
participants
used
one
of
three
approaches,
each
with
its
own
set
of
rules:

°
Assess
the
use
of
chloramines
 
If
the
use
of
chloramines
is
not
feasible,
then
look
for
another
technology
that
better
addresses
ground
water­
specific
needs,
such
as
multiple
small
entry
points.
Evaluate
whether
these
entry
points
would
be
best
served
by
technologies
such
as
nanofiltration
(
NF)
and
Granular
Activated
Carbon
(
GAC)
rather
than
an
advanced
oxidant
(
ozone).

°
Always
maintain
a
consistent
residual
in
the
distribution
system
 
If
other
plants
in
the
system
use
chlorine
as
a
residual,
the
plant
cannot
select
chloramines
as
its
technology.
In
addition,
chloramines
cannot
be
selected
when
TOC
is
above
a
certain
level.
Microfiltration/
ultrafiltration
(
MF/
UF)
cannot
be
selected
as
a
technology
because
ground
water
plants
are
not
subject
to
the
high
removal
or
inactivation
requirements
of
surface
water
plants.
Other
technologies
are
selected
as
needed.

°
Assess
how
far
the
plant
is
from
compliance
with
the
MCLs.
Determine
whether
the
plant
already
uses
chloramines.
If
chloramines
are
not
used,
and
up
to
a
20
to
30
percent
reduction
of
DBPs
results
in
compliance,
select
chloramines
as
the
final
technology.
If
chloramines
cannot
be
used
based
on
specific
water
quality
conditions,
eliminate
technologies
that
are
not
feasible
and
select
the
least
expensive
technology
that
meets
the
compliance
criteria.

After
assembling
the
completed
technology
selection
results
from
each
Delphi
participant,
quality
control
and
quality
assurance
steps
were
performed
to
ensure
a
consistent
and
usable
data
entry
format.
A
Microsoft
Access
 
database
was
used
to
consolidate
the
participants'
responses.
The
results
were
then
weighted,
with
higher
confidence
responses
receiving
an
additional
weighting
of
25
percent.

The
Delphi
process
concluded
that
ground
water
systems
that
could
not
comply
with
the
standards
of
the
Regulatory
Alternative
would
choose
primarily
from
four
advanced
treatment
technologies:

°
Conventional
treatment
(
with
chloramines)

°
Advanced
disinfectants
(
ozone)

The

with
each
technology
also
was
assessed.
The
results
of
these
evaluations
were
compiled
and
used
as
the
basis
for
the
technology
selection
forecasts.
The
Delphi
results
from
the
bounding
alternatives
were
also
used
to
develop
technology
selections
for
the
additional
regulatory
alternatives
(
discussed
later
in
this
appendix).

presents
the

of

predicted

the

Additional
Regulatory
Alternatives
Following
the
initial
Delphi
process,
the
Microbial­
Disinfectants
and
Disinfection
Byproducts
Advisory
Committee
(
M­
DBP
Advisory
Committee)
asked
the
Delphi
group
to
consider
regulatory
alternatives
in
addition
to
the
original
"
bounding"
alternatives.
These
new
alternatives
considered
a
bromate
MCL,
as
well
as
TTHM
and
HAA5
MCLs.
Two
of
these
new
alternatives
were
considered
in
this
EA
(
the
Preferred
Regulatory
Alternative
and
Alternative
1).

Because
these
alternatives
were
identified
late
in
the
process,
the
Delphi
group
decided
not
to
repeat
the
full
evaluation
to
develop
new
technology
selections
(
a
time
consuming
process),
but
instead
evaluated
the
new
alternatives
based
on
technology
selections
for
the
original
four
alternatives.
Originally,
a
straight
interpolation
between
the
80/
60
RAA
(
the
Stage
1
DBPR)
and
the
40/
30
RAA
(
Regulatory
Alternative
3)
was
used
to
estimate
the
technology
selection
for
the
80/
60
LRAA
alternative.
EPA
later
estimated
that,
because
water
quality
in
ground
water
plants
does
not
generally
fluctuate
as
much
as
it
does
in
surface
water
plants
and
they
monitor
at
only
one
point
for
Stage
1,
technologies
identified
for
the
80/
60
RAA
would
most
likely
be
appropriate
for
maintaining
an
80/
60
LRAA.
Therefore,
technology
selection
for
the
subset
of
plants
not
complying
with
the
80/
60
RAA
was
maintained
for
the
80/
60
LRAA
alternative.
Technology
selection
for
all
other
plants
(
i.
e.,
those
complying
with
80/
60
RAA
but
not
80/
60
LRAA)
was
interpolated
between
the
80/
60
RAA
and
the
40/
30
RAA
regulatory
alternatives.
The
same
technology
selection
for
the
80/
60
LRAA
was
used
for
the
two
IDSE
sensitivity
analyses.

Final
Results
The
percent
of
non­
complying
plants
(
Exhibits
B.
7
through
B.
13)
is
multiplied
by
the
proportion
of
plants
predicted
to
select
various
technologies
to
produce
the
final
technology
selection
results
for
each
regulatory
alternative
and
sensitivity
analyses
(

is
not
included).

15a
presents
results
for
large
ground
water
plants,
and
B.
15b
presents
results
for

plants.

Note
that
for
Regulatory
Alternative
1
and
one
of
the
IDSE
sensitivity
runs,
the
compliance
forecast
was
adjusted
so
that
the
compliance
forecast
delta
from
Stage
1
to
Stage
2
did
not
show
any
systems
removing
technologies
(
negative
forecasts).
This
is
consistent
with
the
methodology
used
for
surface
water
system
compliance
forecasts.

This
appendix
presents
the
Stage

and
Stage

Disinfectants
and
Disinfection
Byproducts
Rule
(
DBPR)
compliance
forecast
results
for
both
surface
water
and
ground
water
systems.
There
are
three
basic
types
of
compliance
forecasts
presented:

°
Technology
Selection
 
The
technology
selection
tables
represent
the
number
and
percent
of
systems
that
have
to
add
a
treatment
technology
to
comply
with
the
rule.
These
results
include
only
the
number
of
systems
that
exceed
rule
maximum
contaminant
levels
(
MCLs
and
must
add
treatment
technology
to
comply
with
the
rule.
Those
plants
that
are
already
using
a
technology
prior
to
the
rule
and
do
not
have
to
add
an
additional
technology
to
comply
are
not
included
in
this
table.
The
technology
selection
numbers
are
based
on
the
pre­
Stage
1
technology
baseline.

°
Technology
Selection
Deltas
 
The
technology
selection
delta
tables
represent
the
incremental
number
of
plants
that
must
add
a
treatment
technology
to
meet
Stage
2
DBPR
regulatory
alternatives
after
predicted
changes
to
meet
the
Stage
1
DBPR.
These
tables
are
calculated
by
subtracting
the
Stage
1
DBPR
technology
selection
tables
from
the
Stage
2
DBPR
technology
selection
tables.
These
tables
are
used
for
costing.

°
Technologies
in
Place
 
The
technologies
in
place
tables
show
the
number
and
percent
of
systems
that
are
using
a
technology,
once
systems
are
in
compliance
with
the
rule.
This
includes
the
systems
predicted
to
add
a
treatment
technology
to
comply
with
the
rule,
and
those
systems
that
were
already
using
the
technology
before
rule
promulgation.

This
Appendix
presents
the
technology
selection
tables
for
the
Stage
1
DBPR
and
the
Stage
2
DBPR,
and
the
technology
selection,
technology
selection
deltas,
and
technologies
in
place
tables
for
the
other
regulatory
alternatives
and
the
sensitivity
analyses.
Compliance
forecasts
are
organized
as
follows
(
see
next
page).

Note:
Some
compliance
forecasts
are
presented
in
the
main

Appendix

Rule
Activity
Schedule
This
appendix
presents
the
year­
by­
year
schedules
for
systems
for
the
following
rule
activities:
capital
and
Operations
and
Maintenance
(
O&
M)
treatment
costs
(
Exhibits
D.
1
and
D.
2),
implementation
(

Initial

System
Evaluation
(
IDSE)
activities
(
Exhibit
D.
4),
annual
routine
monitoring
(
Exhibit
D.
5),
and
significant
excursion
evaluations
(
Exhibit
D.
6).
Schedules
for
State/
Primacy
Agency
activities
are
in
Exhibit
D.
7.
These
schedules
are
based
on
the
Stage
2
implementation
timeline
as
presented
in
the
Executive
Summary
(
Chapter
1).
When
systems
and
States
had
several
years
within
which
to
complete
a
rule
activity,
the
Environmental
Protection
Agency
(
EPA)
assumed
that
the
same
proportion
of
systems
would
perform
the
activity
in
each
year.
EPA
recognizes
that
more
systems
may
start
in
early
or
later
years,
but
believes
that
a
uniform
schedule
is
still
a
reasonable
approximation
nationally.

The
implementation
and
IDSE
schedules
for
small
surface
water
systems
are
adjusted
to
account
for
the
consecutive
systems
that
are
on
the
large
system
schedule.
Based
on
analysis
in
the
Model
System
Report
(
Appendix
A)
(
USEPA
2000c),
approximately
50
percent
of
small
Category
A
consecutive
systems
serving
fewer
than
10,000
people
purchase
from
a
large
system
serving
more
than
10,000
people.

The

the

of

All
data
in
this

derive
from
the

DBPR
Benefits
Model
(
USEPA
2003i).

E.
2
Derivation
of
the
Fraction
of
Pre­
Stage
1
Cancer
Cases
Attributable
to
DBPs
The
quantified
benefits
of
the
Stage
2
DBPR
are
based
on
the
estimated
reduction
in
the
incidence
of
bladder
cancer
cases
among
people
in
the
United
States
population
who
use
chlorinated
drinking
water.

A
key
input
for
deriving
these
benefits
is
the
estimated
number
of
bladder
cancer
cases
that
can
be
attributed
to
using
chlorinated
drinking
water
in
the
absence
of
the
DBP
regulations.
These
estimates
are
derived
from
several
epidemiological
studies
that
were
conducted
in
the
1980s
and
1990s.
Because
those
studies
were
conducted
prior
to
the
implementation
of
the
Stage
1
DBPR,
they
reflect
pre­
Stage
1
DBPR
exposure
conditions.
Consequently,
the
derivation
of
the
benefits
for
the
Stage
2
DBPR
requires
a
multi­
step
process
that
accounts
for
reductions
in
bladder
cancer
incidence
estimates
due
to
the
Stage
1
DBPR
and
furhter
reductions
due
to
Stage
2.
In
summary,
the
steps
are:

This

of
Appendix

focuses
on
the
first
step
in
that
process:
The
derivation
of
the
fraction
of
pre­
Stage

bladder
cancer
cases
that
are
attributable
to
DBPs.
Section
E.
2.1
provides
a
general
discussion
of
how
epidemiological
studies
are
used
to
determine
the
cases
of
a
disease
that
can
be
attributed
to
a
specific
risk
factor.
Mock
data
based
on
bladder
cancer
attributable
to
DBPs
are
used
for
example
calculations
in
Section
E.
2.1.
Section
E.
2.2
provides
details
on
the
specific
epidemiological
data
that
EPA
has
used
to
estimate
the
pre­
Stage
1
incidence
of
bladder
cancer
cases
attributable
to
DBP.
Section
E.
2.2
also
addresses
uncertainties
and
limitations
associated
with
those
data.
Section
E.
2.3
presents
the
estimated
pre­
Stage
1
cancer
incidence
derived
from
the
available
epidemiological
data
including
the
distribution
of
them
among
various
types
of
public
water
supples.
As
discussed
there,
these
estimates
are
presented
as
the
low­
and
high­
end
values
of
the
range
of
attributable
cases
suggested
by
the
data.

E.
2.1
General
Description
of
Population
Attributable
Risk
(
PAR)
Calculations
The
risk
assessment
methodology
used
to
estimate
the
number
of
cancer
cases
that
are
attributable
to
DBPs
in
chlorinated
drinking
water
involves
the
estimation
of
a
PAR
value.
PAR,
which
is
also
referred
to
frequently
and
perhaps
more
appropriately
as
Population
Attributable
Fraction
(
PAF),
is
a
measure
of
the
fraction
of
a
disease
that
occurs
in
the
population
that
is
attributable
to
some
specified
risk
factor.
By
extension,
it
also
implies
the
fraction
of
that
disease
which
would
be
eliminated
from
the
population
if
that
specified
risk
factor
were
eliminated.

For
example,
it
is
currently
estimated
that
there
are
56,500
new
cases
of
bladder
cancer
annually
(
American
Cancer
Society
2002).
As
discussed
in
this
Economic
Analysis
(
EA),
available
epidemiological
data
indicate
an
association
between
bladder
cancer
and
exposure
to
chlorinated
(
disinfected)
drinking
water.
PAR
in
this
case
would
be
the
fraction
of
those
56,500
annual
new
cases
of
bladder
cancer
occurring
in
the
entire
U.
S.
population
that
could
be
attributed
to
exposure
to
disinfected
drinking
water
(
i.
e.,
the
risk
factor).

For
the
purposes
of
illustrating
the
derivation
of
PAR
values,
suppose
that
the
distribution
of
the
bladder
cancer
cases
in
the
population
were
known
with
respect
to
those
who
are
exposed
to
disinfected
water
and
those
who
are
not.
Exhibit
E.

below
provides
a
"
mock"
example
of
such
a
distribution.

Several
measures
in
Exhibit
E.
1
suggest
that
exposure
to
DBPs
is
a
risk
factor
for
cases
of
bladder
cancer.
For
example,
as
shown
in
the
last
column,
the
bladder
cancer
risk
for
exposed
individuals
(
2.03
x
10­
4)
is
higher
than
that
for
unexposed
individuals
(
1.81
x
10­
4).
This
is
further
shown
by
the
Relative
Risk
(
RR)
measure
of
1.123
for
exposed
to
unexposed
individuals.
RR
is
an
important
measure
in
evaluating
epidemiological
data.

Another
important
measure
used
in
evaluating
epidemiological
data
is
the
Odds
Ratio
(
OR).
The
odds
of
an
event
occurring
are
simply
the
ratio
of
the
number
of
events
to
the
number
of
non­
events.
So,
in
the
example
used
here
the
odds
of
a
case
being
exposed
is
10.61
(
51,632
/
4,868)
whereas
the
odds
of
a
non­
case
being
exposed
is
9.44
(
254,426,956
/
26,938,450).
The
OR
for
exposed
to
non­
exposed
cases
is
1.123.
Economic

the

It
is
important
to
note
that
the
identical
value
of
1.123
for
both
the
OR
and
RR
in
this
example
does
not
imply
that
they
are
identical
measures.
As
will
be
discussed
further
below,
RR
is
the
desired
measure
for
calculating
PAR
from
sample
data;
however,
an
OR
is
often
more
readily
obtained
from
available
studies
and
can
under
appropriate
conditions
be
used
as
an
approximation
of
RR.

One
other
measure
of
a
relationship
between
exposure
and
increased
incidence
shown
in
Exhibit
E.
1
is
that
the
probability
of
having
been
exposed
for
someone
who
has
bladder
cancer
(
0.914)
is
higher
than
the
probability
of
having
been
exposed
for
someone
who
does
not
(
0.904).

There
are
alternative
ways
to
calculate
PAR
using
various
measures
of
risk.
The
most
direct
method
would
be
to
calculate
PAR
from
the
difference
between
the
risk
in
the
entire
population
(
R
t)
and
the
risk
in
the
unexposed
population
(
R
u)
divided
by
the
total
risk:

PAR
=
Rt
­
Ru
=
2.01x10­
4
­
1.81x10­
4
=
0.10
=
10%
(
Equation
E.
1)
Rt
2.01x10­
4
That
is,
this
example
would
imply
that
10%
of
the
56,500
bladder
cancer
cases
are
due
to
exposure
to
DBPs.

One
can
also
calculate
PAR
from
the
information
provided
by
the
RR
and
probability
of
exposure
in
the
overall
population:

PAR
=
Pe/
t
(
RR
­
1)
=
0.904
x
(
1.123
­
1)
=
0.1112
=
0.10
=
10%
(
Equation
E.
2)
[
Pe/
t
(
RR
­
1)]
+
1
[
0.904
x
(
1.123
­
1)]
+
1
1.1112
Equation
E.
2
is
essentially
a
transformation
of
Equation
E.
1.

A
third
method
for
calculating
from
this
data
is:

PAR
=
Pe/
c
[
RR
­
1
/
RR]
=
0.914
[
1.123
­
1
/
1.123]
=
0.914x
0.1095
=
0.10
=
10%
(
Equation
E.
3)

In
this
third
formulation
for
calculating
PAR,
the
value
obtained
from
the
quantity
(
RR­
1
/
RR)
is
a
direct
measure
of
the
attributable
fraction
within
the
exposed
group.
That
is,
in
this
example,
10.95%
of
the
cases
within
the
exposed
group
are
attributable
to
that
exposure,
or
0.1095
x
C
e.
The
corresponding
fraction
of
total
cases
due
to
exposure
is,
then,
(
0.1095
x
C
e)
/
C
t),
or
0.1095
x
(
C
e/
C
t)
which
is
0.914
x
0.1095
=
10%.

A
more
detailed
discussion
of
these
alternative
methods
of
calculating
PAR
is
provided
in
Rockhill
et
al.
(
1998),
who
also
provide
some
additional
information
regarding
limitations
on
the
use
of
these
approaches.
The
major
limitation
they
note
is
that
Equations
E.
1
and
E.
2
are
only
valid
as
shown
here
when
there
is
no
confounding,
whereas
Equation
E.
3
can
be
used
to
provide
internally
valid
estimates
when
confounding
exists
(
examples
of
possible
confounding
factors
include
age,
sex,
smoking
history,
occupation,
socioeconomic
status).

Of
course,
having
information
such
as
that
presented
in
the
mock
data
above
for
the
entire
population
is
extremely
rare,
and
PAR
values
are
typically
estimated
from
representative
sample
data
provided
in
epidemiological
studies.
There
are
two
primary
types
of
epidemiological
studies
that
can
provide
data
for
estimating
PAR:
cohort
(
prospective)
studies
and
case­
control
(
retrospective)
studies.

Cohort
studies
can
most
directly
provide
the
data
needed
for
PAR
calculations.
In
these
studies,
sample
populations
are
selected
at
random
to
be
representative
of
exposure
to
the
risk
factor
of
interest.
That
is,
a
prospective
study
would
ideally
involve
the
selection
of
a
sample
population
that
is
representative
of
the
distribution
of
exposure
(
that
is,
reflecting
the
rows
in
Exhibit
E.
1)
without
any
prior
consideration
of
the
presence
or
absence
of
the
disease
in
the
sample.
A
major
problem
with
prospective
studies
is
that
when
the
disease
of
interest
is
relatively
rare,
a
very
large
sample
group
is
required
in
order
to
obtain
a
sufficient
number
of
cases
of
the
disease
for
subsequent
analysis.

For
example,
if
one
were
to
attempt
a
prospective
study
for
a
disease
having
risk
factors
similar
to
those
assumed
for
bladder
cancer
in
this
example
(
approximately
2
x
10­
4),
it
would
be
necessary
to
have
a
sample
population
of
at
least
1,000,000
people
(
and
likely
more
than
that)
to
ensure
observation
of
enough
cases
to
be
able
to
estimate
RRs
and
PAR
values.
Exhibit
E.
2,
provides
a
mock
display
of
such
a
prospective
study.
In
this
example,
the
researchers
would
target
a
sample
of
1,000,000
individuals
whose
exposure
would
be
reflective
of
the
more
than
281
million
in
the
overall
population
who
they
are
meant
represent.

Assuming
also
that
the
observed
incidence
of
cases
for
the
exposed
and
unexposed
groups
reflect
the
actual
risks
in
those
underlying
populations
(
as
shown
in
Exhibit
E.
1),
then
one
would
expect
a
total
of
only
201
cases
in
the
entire
1,000,000
sample
group
 
78
in
the
exposed
subset
and
a
mere
23
in
the
unexposed
subset.

If
one
were
actually
able
to
carry
out
such
a
study,
then
PAR
could
be
calculated
using
these
data
and
the
methods
described
previously.
However,
it
should
be
obvious
from
the
sample
size
requirements
alone
that
prospective
studies
for
diseases
with
such
a
low
frequency
of
occurrence
are
highly
impractical,
and
indeed
they
are
rarely
conducted.

The
alternative
study
approach
 
and
that
which
has
been
used
in
the
epidemiological
studies
included
in
this
EA
 
is
to
use
retrospective
case­
control
studies.
These
have
the
advantage
of
a
more
practical
sample
size.
Their
potential
disadvantage,
however,
is
that
one
cannot
calculate
RR
values
for

directly

However,
it
is
possible
to
calculate
an
OR
from
a
case­
control
study
which,
under
appropriate
conditions,
can
be
used
as
an
estimate
of
RR
for
PAR
calculations.

In
a
typical
case­
control
epidemiological
study,
a
researcher
would
identify
a
group
of
cases,
ideally
selected
in
a
manner
that
is
unbiased
with
respect
to
the
underlying
exposure
factor
of
interest.
Similarly,
a
set
of
controls
(
non­
cases)
would
be
selected
in
a
manner
that
is
also
unbiased
with
respect
to
the
underlying
exposure
factor
of
interest.
Exhibit

presents
a

of
mock

for
such

For
this

it
is
assumed
that
the

identifies
201

and
that
these
are
found
(
ideally)
to
be
distributed
as
expected
(
based
on
our
overall
mock

set)
with
respect
to
exposure.
The
researcher
also
selects
a
set
of
controls
not
having
the
disease
(
1,000
assumed
here),
also
distributed
ideally
in
a
manner
that
is
representative
of

for

this,

(

therefore

would
be
meaningless
and
entirely
an
artifact
of
the
number
of
cases
and

selected.
Therefore,
it
is
not
possible
to
use
Equation
1
to
calculate
PAR
values
from
a
case­
control
study.
However,
it
is
possible
to
calculate
the

that

the

executed
in
a
manner
that
meets
three
main
conditions,
the
OR
can
be
used
as
an
estimate
for
RR,
allowing
PAR
to
be
calculated
from
the
alternative
formulations:

°
The
disease
being
considered
occurs
at
a
low
frequency
in
the
studied
population.

°
The
cases
have
been
selected
in
a
manner
that
is
representative
with
regard
to
the
history
of
exposure
of
all
people
with
the
disease
in
the
population
from
which
they
are
drawn.

°
The
controls
have
been
selected
in
a
manner
that
is
representative
with
regard
to
the
history
of
exposure
of
all
people
without
the
disease
in
the
population
from
which
they
are
drawn.

If
these
conditions
are
met,
then
the
OR
will
be
a
reasonable
estimate
of
the
RR
and
can
be
used
in
place
of
RR
in
Equations
2
or
3
for
calculating
PAR.

It
is
important
to
note,
however,
that
the
use
of
Equation
2
is
limited
to
circumstances
where
there
is
no
confounding
and
ORs
calculated
directly
as
shown
here
are
used
(
see
Rockhill
et
al.
1998).
Usually,
however,
this
is
not
the
case
and
it
is
necessary
in
a
case­
control
study
to
adjust
for
confounding
factors.
This
is
often
done
by
computing
ORs
that
take
into
account
the
interactions
of
multiple
(
potential)
risk
factors
by
the
use
of
logistic
regression
techniques.
In
such
cases,
Equation
3
is
the
appropriate
equation
to
use
to
calculate
PAR.
Using
the
case
control
study
example
here,
that
calculation
would
be:

PAR
=
Pd
[
OR
­
1
/
OR]
=
0.915
x
[
1.149
­
1
/
1.149]
=
0.915
x
0.1297
=
0.119
=
11.9%

In
the
foregoing
examples
of
PAR
calculations,
the
population
is
stratified
into
two
exposure
groups
only:
those
with
and
those
without
exposure.
More
often,
multiple
exposure
groups
are
used
to
reflect
potential
relationships
between
exposure
levels
and
risk.
For
PAR
calculations
involving
multiple
exposure
groups,
the
PAR
equations
shown
above
as
Equations
E.
2
and
E.
3
can
be
modified
as
follows:

The
first
of
these
multiple­
exposure­
group
forms
of
the
PAR
calculations
corresponds
to
Equation
E.
2
and
the
second
to
Equation
E.
3.
They
both
indicate
that
there
are
"
k"
exposure
categories,
including
an
unexposed
referent
group
for
which
the
RR
=
1
(
or
OR
=
1
if
ORs
are
being
used
in
place
of
RR).
These
equations
are
also
addressed
more
fully
in
Rockhill
et
al.
(
1998).
As
indicated
in
the
next
section,
Economic
Analysis
for
the
Stage
2
DBPR
Proposal
E­
8
July
2003
the
second
of
these
equations
for
multiple
exposure
categories
was
used
to
compute
PARs
from
the
epidemiological
data
for
bladder
cancer
associated
with
exposure
to
chlorinated
drinking
water.

It
is
also
useful
to
note
that
calculation
of
the
ORs
from
epidemiological
data
where
there
are
multiple
exposure
categories
and
where
there
is
a
need
to
adjust
for
confounding
factors
(
e.
g.,
age,
sex,
smoking,
occupation,
socioeconomic
status,
etc.)
generally
is
performed
using
logistic
regression
methods
rather
than
the
simple
method
shown
above.
As
noted
in
the
following
section,
logistic
regression
methods
were
used
to
compute
the
ORs
for
the
specific
studies
used
to
estimate
PARs
for
pre­
Stage

bladder
cancer
incidence
used
in
this
EA.

summarizes
the

from
the
five
studies
(
note
that
Cantor
et
al.
1985
and
Cantor
et
al.
1987
use
the
same
epidemiological
data)
used
to
calculate
PAR
values
for
pre­
Stage
1
bladder
cancer
incidence.
These
studies
are
discussed
more
fully
in
Chapter
5
of
the
EA.
The
ORs
and
their
95%
confidence
intervals
for
each
exposure
group
were
calculated
by
the
researchers
performing
these
studies.

EPA
calculated
PAR
values
from
the
data
shown
in
Exhibit
E.
4
using
the
multiple­
exposuregroup
form
of
Equation
E.
3
as
described
in
Section
E.
2.1,
above.
These
calculations
and
the
resulting
PAR
values
are
shown
in
Exhibit
E.
5.
The
PAR
estimates
shown
in
Exhibit
E.
5
reflect
the
point
estimates
of
the
ORs
for
each
exposure
group
in
each
study.
As
shown
in
Exhibit
E.
4,
the
researchers
for
those
studies
also
presented
95%
confidence
intervals
for
those
ORs,
reflecting
uncertainty
in
the
values.

EPA
has
calculated
corresponding
95%
confidence
intervals
on
the
PAR
point
estimates
shown
in
Exhibit
E.
5
using
a
Monte
Carlo
simulation
analysis.
The
confidence
intervals
on
the
ORs
reported
by
the
researchers
were
used
to
parameterize
each
OR
as
a
normal
distribution.
For
each
study,
10,000
iterations
were
run;
the
OR
for
each
exposure
group
was
selected
from
its
respective
uncertainty
distribution
assuming
independence
among
the
groups
(
and
among
the
studies).
PAR
values
were
calculated
(
using
the
computation
as
shown
in
Exhibit
E.
4)
for
each
of
the
10,000
iterations
and
accumulated.

Using
the
10,000
PAR
estimates
for
each
study,
lower
and
upper
confidence
bounds
were
derived.
The
upper
95%
confidence
limit
is
taken
from
the
97.5
percentile
values.
The
lower
limit
is
taken
from
the
2.5
percentile
values
of
the
10,000
values,
unless
those
values
are
below
zero,
in
which
case
the
lower
confidence
interval
is
assumed
to
be
0%
because
it
is
biologically
implausible
that
the
true
PAR
value
should
be
less
than
0%.
The
confidence
intervals
obtained
from
the
Monte
Carlo
simulation
are
summarized
in

In
addition
to
the
uncertainty
in
the
PAR
values
calculated
for
each
of
the
individual
studies
as
reflected
by
the
confidence
intervals,
it
is
important
to
consider
the
uncertainty
associated
with
the
use
of
those
studies
 
each
of
which
was
based
upon
a
specific
subset
of
the
entire
US
population
 
to
represent
the
PAR
value
for
the
US
population
as
a
whole.

One
important
consideration
in
this
regard
is
the
extent
to
which
exposure
in
the
study
population
groups
is
comparable
to
exposure
in
the
overall
US
population.
Exhibit
E.
7
provides
an
overall
summary
of
the
percent
of
cases
and
controls
in
each
study
who
were
in
the
DBP
exposure
groups
(
across
all
exposure
durations).
As
shown
in
this
exhibit,
the
exposure
groups
typically
range
from
65
 
80%
of
the
study
populations,
with
one
instance
(
Cantor
1998)
where
only
about
35
 
40%
of
the
study
population
were
exposed
to
DBPs.
It
is
currently
estimated
that
approximately
90%
of
the
US
population
consumes
water
from
public
water
supplies
that
are
disinfecting,
and
the
vast
majority
of
these
systems
use
chlorination.
As
a
result,
it
can
be
argued
that
the
PAR
values
obtained
from
these
five
epidemiological
studies
under­
represent
exposure
in
the
United
States,
and
that
the
actual
PAR
values
are
higher
than
suggested
by
the
values
calculated
and
used
in
this
EA.

Lastly,
it
is
important
to
recognize
that,
notwithstanding
the
associations
indicated
by
these
studies,
causality
has
not
yet
been
established
between
bladder
cancer
and
exposure
to
chlorinated
water.
Therefore,
the
attributable
risk
from
chlorinated
water
may
be
zero.

and

analyses
reflect
the
range
of
best
estimates
derived
from
the
relevant
epidemiological
data
(
See
Exhibit
E.
6).
EPA
recognizes
that
the
lower
bound
may
be
as
low
as
zero
since
causality
has
not
yet
been
established
between
exposure
to
chlorinated
water
and
bladder
cancer.

Number

is
rounded
to

because
the
American
Cancer
Society
data
is
only
reported
to
the

No
specific
information
is
available
regarding
the
possible
distribution
of
cancer
cases
among
people
served
by
water
systems
of
different
sizes
and
sources.
As
a
starting
point,
EPA
allocated
cancer
cases
attributable
to
DBPs
to
systems
of
different
sizes
and
sources
based
on
relative
population
served.
In
addition,
EPA
assumed
that
systems
with
comparable
populations
but
higher
pre­
Stage
1
DBP
concentrations
would
have
a
larger
share
of
cases
than
systems
with
lower
levels.
Therefore,
rather
than
simply
multiplying
the
number
of
cancer
cases
attributable
to
DBPs
by
the
proportion
of
the
population
served
by
a
given
system
size
and
source
category,
EPA
weighted
the
proportion
by
DBP
occurrence
levels.

To
distribute
the
cases,
the
population
served
by
a
given
size
and
source
category
was
first
multiplied
by
the
mean
DBP
occurrence
level
for
that
category
(
derivation
of
mean
pre­
Stage
1
DBPR
occurrence
is
presented
in
section
E.
3).
This
number
was
then
divided
by
the
sum
of
all
"
population
×
DBP"
for
each
source
and
size
category
to
get
a
percentage
that
is
weighted
for
DBP
occurrence.
Finally,
this
weighted
percentage
was
multiplied
by
the
total
number
of
cancer
cases
attributable
to
DBPS.
Exhibits

these
calculations
and

Economic
Analysis
for
the
Stage
2
DBPR
Proposal
E­
15
July
2003
For
large
surface
water
systems,
EPA
considered
using
observed
ICR
data
for
characterizing
pre­
Stage
1
occurrence.
EPA
decided,
however,
to
use
SWAT­
predicted
results
instead
of
observed
ICR
data
to
allow
for
a
more
precise
analysis
of
Stage
1
reduction
rates,
since
these
are
obtained
by
comparing
SWAT­
predicted
pre­
Stage
2
occurrence
data
to
pre­
Stage
1
occurrence
data3.
These
estimated
rates
of
Stage
1
DBP
reduction
for
large
surface
water
systems
are
key
in
this
analysis
because
they
are
used
as
a
basis
for
estimating
Stage
1
reductions
in
all
other
system
classes
(
small
surface
water
and
all
ground
water).

For
small
surface
water
systems,
National
Rural
Water
Association
(
NRWA)
survey
data
are
used
to
estimate
mean
pre­
Stage
1
occurrence
(
USEPA
2001c).
In
the
distribution
system,
NRWA
samples
were
collected
at
two
locations
 
the
location
with
the
maximum
residence
time
and
one
location
with
an
average
residence
time.
To
make
the
NRWA
plant­
mean
data
comparable
to
ICR
data
(
and
thus
to
SWAT­
predicted
results),
the
NRWA
average
residence
time
data
were
weighted
three
times
more
heavily
than
the
maximum
residence
time
samples
to
produce
the
mean
pre­
Stage
1
occurrence.

For
large
ground
water
systems,
mean
pre­
Stage
1
TTHM
and
HAA5
concentrations
are
derived
from
ICR
data.
Only
those
plants
that
had
data
for
at
least
3
of
the
last
4
quarters
of
the
ICR
and
for
at
least
3
of
4
distribution
system
locations
for
each
of
those
quarters
were
included
in
the
analysis.

For
small
ground
water
systems,
pre­
Stage
1
TTHM
concentrations
are
based
on
analyses
of
data
submitted
directly
from
seven
States
in
1998
and/
or
1999
(
see
the
Stage
2
DBPR
occurrence
document
[
USEPA,
2003l]
for
description
of
State
data
analysis).
For
HAA5,
no
occurrence
data
are
available
for
small
ground
water
systems,
so
the
mean
of
HAA5
plant­
means
is
estimated
by
multiplying
the
mean
HAA5
value
for
large
ground
water
systems
by
the
ratio
of
TTHM
levels
in
small
ground
water
plants
to
TTHM
in
large
ground
water
plants.

Reduction
in
DBP
occurrence
from
Pre­
Stage
1
to
Pre­
Stage
2
and
from
Pre­
Stage
2
to
Post­
Stage
2
All
estimates
of
DBP
reductions
from
both
Stage
1
compliance
(
pre­
Stage
1
to
pre­
Stage
2)
and
the
Stage
2
compliance
(
pre­
Stage
2
to
post­
Stage
2)
are
based
on
SWAT
model
results
for
large
surface
water
systems.
For
example,
to
estimate
the
Stage
1
reduction,
the
difference
between
SWAT­
predicted
pre­
Stage
2
and
pre­
Stage
1
occurrence
levels
is
divided
by
pre­
Stage
1
occurrence
to
obtain
a
percentage
change.
Analogous
SWAT­
modeled
reductions
for
other
system
classes
(
small
surface
water
and
all
ground
water)
are
not
available.
Instead,
these
are
based
on
the
large
surface
water
results
in
combination
with
some
additional
assumptions,
as
discussed
below.

For
small
surface
water
systems,
the
EPA
assumes
that
pre­
Stage
2
and
post­
Stage
2
DBP
occurrence
levels
will
be
similar
to
those
in
large
surface
water
systems.
Reductions
are
then
estimated
as
the
difference
between
the
large
surface
water
occurrence
estimates
(
levels
for
both
pre­
Stage
2
and
post­
Stage
2)
and
the
NRWA
estimates
that
provide
the
pre­
Stage
1
baseline
for
small
surface
water
systems.

forecasts

Chapter

description
of
the

to

The
purpose
of
this

is
to
provide
the

necessary
to
produce
the
final
annual
cancer

avoided.

Exhibit

Introduction
and
Purpose
The
purpose
of
this
Appendix
is
to
support
Section
5.9.1
by
providing
details
for
an
illustrative
calculation
that
quantifies
the
benefits
of
reduced
fetal
losses
(
miscarriage
and
stillbirth)
potentially
attributable
to
the
reduction
in
elevated
DBP
levels
from
the
Stage
2
DBPR.
Fetal
loss
was
chosen
from
among
the
reported
reproductive
and
developmental
health
endpoints
(
including
neural
tube
defects,
low
birth
weight,
cardiovascular
effects,
intrauterine
growth
retardation
and
cleft
palate,
etc.)
because
there
are
relatively
more
epidemiological
data
for
it
in
comparison
to
the
other
endpoints.
In
addition,
fetal
loss
occurs
at
a
high
incidence
rate
in
the
US;
of
the
approximately
six
million
pregnancies
experienced
in
the
US
each
year,
approximately
one
million
end
as
fetal
losses
(
Ventura
et
al.
2000a).
Consequently,
even
a
small
risk
attributable
to
DBPs
(
e.
g.,
0.1
percent)
may
result
in
a
large
number
of
fetal
losses
(
n=
1,000)
and,
thus,
increase
potential
benefits
from
avoided
cases
of
fetal
losses
for
the
Stage
2
DBPR.

Section
G.
2
describes
the
derivation
of
PAR
values
relating
fetal
losses
to
DBP
exposure.
Section
G.
3
presents
the
calculation
of
fetal
losses
avoided
as
a
result
of
the
Stage
2
DBPR.
Assumptions
and
uncertainties
in
these
calculations
are
summarized
in
Section
G.
4.

Derivation
of
PARs
from
Three
Studies
Fetal
losses
potentially
attributable
to
DBPs
in
drinking
water
were
estimated
use
the
PAR
approach,
similar
to
the
approach
used
to
quantify

PAR
is
a
measure
of
the
fraction
of
a
disease
that
occurs
in
the
population
that
is
attributable
to
some
specified
risk
factor.
By
extension,
it
also
implies
the
fraction
of
that
disease
that
would
be
eliminated
from
the
population
if
the
specified
risk
factor
was
eliminated.

To
derive
PAR,
EPA
evaluated
three
separate,
published
population­
based
human
epidemiology
studies:

Exhibit

summarizes
the
key
characteristics
of
these

All
three
are
considered
high
quality
studies
as
they
conform
to
the
following
criteria:
1)
population­

case­
control
or
cohort
study
that
ascertained
exposure
to
chlorinated

2)
high

that
had
sufficient
sample
sizes,
high

rates1,
and
adjusted
for
known
confounding
factors,
and
3)

from
epidemiological
studies
The
three
epidemiological
studies
used
in
this
analysis
differ
in
geographic
location,
health
endpoints,
study
type,
and
exposure
classification.
Major
features
of
the
studies
are
summarized
in
Exhibit

studies
assigned
pregnancies
to
multiple

the

those
closest

Comparison
of
exposure
between
ICR
data
and
study
populations
EPA
derived
national
exposure
estimates
based
on
the
ICR
data
using
the
exposure
study
definitions
by
Waller
et
al.
2001,
Savitz
et
al.
1995,
and
King
et
al.
2000a.
For
the
Waller
study,
EPA
used
the
first
trimester
utility
wide
average,
rather
than
the
closest­
site
estimate,
as
only
this
definition
could
be
applied
to
the
ICR
data.
This
assumption
is
supported
by
the
Waller
et
al.
2001
comment
that
there
is
little
difference
between
the
exposure
estimates
derived
from
the
utility­
wide
average
versus
the
closest­
site
estimates.
In
analyzing
the
ICR
data
for
purpose
of
exposure
comparison
with
the
Waller
study,
EPA
considered
the
plants
having
data
from
at
least
3
distribution
system
locations
with
at
least
three
valid
results
for
both
TTHM
and
HAA5
during
the
final
year
of
the
ICR
survey,
i.
e.,
ICR
quarters
3,
4,
5,
and
6.
Among
these
plants,
77
out
of
1,130
plant­
quarters
(
6.8
percent)
had
distribution
system
averages
greater
than
80
m
g/
L,
and
therefore
are
categorized
as
high­
exposure
per
Waller.
The
Savitz
study
also
used
utility
wide
averages
in
a
given
quarter
as
the
basis
for
the
exposure
estimates.
Thus,
the
6.8
percent
exposure
estimate
from
the
ICR
data
for
Savitz
is
essentially
the
same
as
for
Waller
since
the
population
cutoffs
are
only
different
by
1
m
g/
L,
i.
e.,
80
vs
81
m
g/
L.

For
the
King
study,
exposure
was
estimated
by
averaging
predicted
TTHM
values
for
the
months
covering
the
duration
of
the
mother's
pregnancy
and
using
75
m
g/
L
as
the
exposure
concentration
for
comparisons.
To
relate
the
King
exposure
estimate
to
the
ICR
data,
EPA
calculated
locational
nine
month
running
averages
from
the
ICR
data;
i.
e.,
locational
averages
for
3
consecutive
quarters.
Each
ICR
plant
location
provided
three
or
four
nine­
month
averages,
taking
quarters
(
3,4,5),
(
3,4,6),
(
3,5,6),
or
(
4,5,6).
Of
the
4,917
location­
nine­
month
averages
from
the
ICR
data,
314
(
6.4%)
exceeded
75
m
g/
L,
and
therefore
are
categorized
as
high­
exposure
per
King.

Estimate
of
Annual
Fetal

Avoided
as
a
Result
of
the
Stage

DBPR
All
three
epidemiology
studies
covered
exposure
periods
that
occurred
between
1988
and
1995,
before
implementation
of
the
Stage
1
DBPR.
To
calculate
the
number
of
fetal
losses
avoided
as
a
consequence
of
the
Stage
2
DBPR,
TTHM
quarterly
distribution
system
data
collected
during
the
ICR
were
used
to
estimate
the
fraction
of
locations
with
peak
exposures
for
pre­
Stage
1,
pre­
Stage
2
(
post­
Stage
1),
and
post­
Stage
2
scenarios.
From
these
fractions,
the
percent
reduction
in
peak
exposures
attributed
to
the
Stage
2
DBPR
can
be
calculated
(
See
section
5.4.1
and
Exhibit
5.13
for
a
discussion
of
this
analysis).
Although
EPA
recognizes
that
the
developmental
and
reproductive
health
data
described
in
section
5.2
does
not
conclusively
identify
the
peak
level
of
concern,
a
peak
TTHM
concentration
of
80
:
g/
L
was
assumed
for
all
analyses,
since
this
was
closest
to
the
level
evaluated
in
the
studies.

EPA
made
several
assumptions
for
this
analysis.
For
example,
each
ICR
plant­
location
(
DSE,
AVG1,
AVG2,
and
DS
Maximum)
was
assumed
to
represent
an
equal
portion
of
the
population.
Also,
TTHM
occurrence
for
ICR
plants
evaluated
are
assumed
to
represent
national
occurrence.
Section

provides
a
full
discussion
of
the
assumptions
and
uncertainties
for
the
derivation
of
fetal
losses
avoided
as
a
result
of
the
Stage

DBPR
EPA
estimates
that
approximately
1,100
to
4,700
fetal
losses
could
be
avoided
per
year
as
a
result
of
the

Summary
of
Assumptions
and
Uncertainties
There
are
a
number
of
uncertainties
and
assumptions
associated
with
calculating
PAR
and
deriving
the
estimate
of
Fetal
Losses
that
could
be
attributable
to
DBP
exposure.
The
assumptions
are
necessary,
however,
for
predicting
exposure
changes
given
the
limited
data
on
DBP
occurrence
in
small
systems
and
in
distribution
systems
in
general.
These
include:

°
DBPs
may
not
be
the
causative
agent
for
these
fetal
losses.

°
All
confounding
factors
may
not
have
been
considered
in
these
three
studies.

°
By
using
the
crude
odds
ratios
to
recalculate
the
risk
estimates,
the
PAR
estimates
may
not
have
captured
the
true
risk
estimate.

°
The
total
incidence
for
all
fetal
losses
(
n=
983,000)
was
used
to
represent
both
spontaneous
abortion
and
stillbirth
because
there
is
insufficient
data
to
distinguish
the
number
of
miscarriages
vs.
number
of
stillbirths
per
year.

These
assumptions
and
uncertainties
are
not
all
specific
to
this
analysis;
they
would
be
true
for
many
environmental
epidemiology
studies
and
population
attributable
risk
calculations.

There
are
other
uncertainties
and
assumptions
associated
with
calculating
the
reduction
in
fetal
losses
that
could
be
attributable
to
the
Stage
2
DBPR.
To
translate
DBP
occurrence
to
DBP
exposure,
two
assumptions
were
used.

°
Each
plant­
location
(
DSE,
AVG1,
AVG2,
and
DS
Maximum)
represents
an
equal
portion
(
25
percent)
of
the
total
population
served
by
the
plant.

°
Peak
DBP
occurrence
for
311
large
ICR
plants
evaluated
is
representative
of
the
peak
DBP
occurrence
for
all
plants
(
large
and
small).

Section
5.4.1.3
provides
an
assessment
of
the
validity
and
impact
of
these
assumptions.

Because
DBP
concentrations
are
highly
variable
in
distribution
systems,
it
is
possible
that
the
exposure
analysis
in
Section
5.4.1.3
does
not
capture
true
variability
in
exposure
to
peaks.
Uncertainties
with
interpretation
of
ICR
data
for
the
purposes
of
this
exposure
assessment
include:

°
The
extent
to
which
small
system
occurrence
is
represented
°
Year
to
year
variability
of
DBP
occurrence
data
that
might
be
affected
by
changes
in
source
water
quality
(
e.
g.,
drought
years
versus
non­
drought
years)

°
The
extent
to
which
each
ICR
sampling
point
represents
an
equal
fraction
of
the
population
served
°
The
extent
to
which
ICR
sampling
locations
represent
compliance
monitoring
locations
when
trying
to
estimate
reductions
in
exposure
resulting
from
compliance
with
Stage
1
and
Stage
2
DBPRs.
