This
appendix
presents
calculation
summaries
and
cost
tables
for
Stage

Disinfectants
and
Disinfection
Byproducts
Rule
(
DBPR)
activities
associated
with
rule
implementation,
Initial
Distribution
System
Evaluations
(
IDSEs),
additional
routine
monitoring,
and
significant
excursion
evaluations.
It
supports
the
discussion
of
these
rule
activities
in
Chapter
6.
For
systems,
each
activity
is
described
separately
in
sections
H.
2
through
H.
5.
A
summary
of
all
non­
treatment
activities
and
costs
for
systems
is
presented
in

State/

activities
are
described
in

Each
of
the
cost
summaries
presented
in
this
appendix
detail
the
labor
hours
and
corresponding
labor
costs
for
each
activity.
The
derivation
of
the
labor
rates,
based
on
Bureau
of
Labor
Statistics
(
BLS)
2000
data
(
published
in
2001),
used
for
each
activity
is
discussed
in
further
detail
in
Chapter
6
(
section
6.1.1.1).

H.

Derivation
of
the
Stage
2
Monitoring
Baseline
The
Stage
2
DBPR
monitoring
requirements
(
both
IDSE
and
compliance
monitoring)
are
based
on
alternative
system
size
category
breakouts
which
the
Environmental
Protection
Agency
(
EPA)
believes
to
be
more
appropriate
for
setting
forth
numbers
of
samples
per
system
than
the
standard
nine
system
size
categories
used
to
generate
treatment
costs
in
this
Economic
Analysis
(
EA).
Thus,
a
separate
Stage
2
monitoring
baseline
for
systems
is
needed.
The
final
Stage
2
DBPR
monitoring
baseline,
as
presented
in
Columns
F
through
I
in
Exhibit
H.
2,
is
derived
using
three
steps
as
described
below.

DBPR
Monitoring
Categories
Exhibit
H.
1
(
the
baseline
adjustment
matrix)
shows
the
percentage
of
systems
in
the
EPA's
nine
standard
categories
that
are
in
the
Stage
2
monitoring
size
categories
based
on
evaluation
of
Safe
Drinking
Water
Information
System
(
SDWIS)
4th
Quarter
2000
Frozen
data.
1
The
first
step
in
developing
the
Stage
2
monitoring
baseline
is
to
multiply
the
number
of
disinfecting
systems
in
the
Stage
2
system
baseline
(
Exhibit
3.3)
by
the
baseline
adjustment
matrix
to
place
systems
in
the
appropriate
categories
for
monitoring
costs.
For
example,
according
to
the
Stage
2
system
baseline
(
Exhibit
3.3,
sum
of
columns
G
and
H),
there
are
911
purchased
surface
water
and
mixed
community
water
systems
(
CWSs)
serving
a
population
between
3,301­
10,000
(
a
standard
size
category).
To
move
these
systems
into
the
Stage
2
monitoring
size
categories,
40.2
percent
(
or
366
systems)
are
placed
in
the
monitoring
population
category
of
500­
4,999,
58.4
percent
(
or
532
systems)
are
placed
in
the
monitoring
population
category
or
5,000­
9,999,
and
1.4
percent
(
or
13
systems)
are
placed
in
the
monitoring
population
category
of
10,000­
24,999).

The
results
of
this
step
are
shown
in
columns
A
through
C
in
Exhibit
H.
2.
Note
that
the
total
number
of
systems
in
the
Stage
2
monitoring
baseline
(
Exhibit
H.
2,
column
C)
is
the
same
as
the
total
number
of
systems
in
the
Stage
2
DBPR
system
baseline
(
Exhibit
3.3,
column
K).

As
described
in
the
Stage

DBPR
rule
language,
"

include
consecutive
system
entry
points
that
operate
for
at
least
60
consecutive
days
per
year.

For
the
purposes
of
this
EA,
systems
supplying
ground
water
under
the
influence
of
surface
water
(
GWUDI)
are
included
with
surface
water
systems.
EPA
also
refers
to
the
grouping
of
surface
water
and
GWUDI
systems
as
"
subpart
H"
systems
in
the
Stage
2
DBPR
rule
language.
Surface
water
and
GWUDI
systems
are
grouped
together
because
they
fall
under
the
same
requirements
in
the
Safe
Drinking
Water
Act
(
SDWA)
regulations.

Step
2
­
Differentiate
100
Percent
Purchasing
Systems
from
Other
Systems
The
second
step
in
developing
the
Stage
2
monitoring
baseline
involves
differentiating
systems
according
to
their
buying
and
selling
relationships
with
other
systems.
This
is
needed
because
the
Stage
2
DBPR
uses
two
monitoring
approaches
for
the
IDSE
and
for
compliance
monitoring
based
on
selling
and
buying
relationships:

°
The
population­
based
monitoring
is
dependent
only
on
source
water
type
and
population
served
and
applies
only
to
consecutive
systems2
that
buy
or
otherwise
receive
all
of
their
finished
water
from
another
system.

°
The
plant­
based
monitoring
approach
is
dependent
on
source
water
type,
population
served,
AND
number
of
plants3
in
a
system
(
consistent
with
Stage
1
DBPR
compliance
monitoring)
and
applies
to
systems
that
produce
some
or
all
of
their
own
finished
water.

Population
and
plant­
based
monitoring
approaches
are
discussed
further
in
sections
H.
3
and
H.
4.
For
the
purposes
of
this
EA,
systems
that
buy
all
of
their
water
are
called
"
100
percent
purchasing
systems."
Systems
that
do
not
buy
all
of
their
water
(
i.
e.,
systems
that
produce
some
or
all
of
their
own
water)
are
called
"
producing
systems."
Baselines
for
each
IDSE
and
additional
routine
monitoring
activity
are
presented
separately
for
these
two
categories
in
this
appendix.

SDWIS
purchased
system
inventory
data
were
used
as
a
starting
point
for
estimating
the
baseline
number
of
100
percent
purchasing
systems.
As
explained
in
Chapter
3,
in
SDWIS
and
the
Baseline
Handbook
(
USEPA
2001h),
systems
are
assigned
a
source
type
using
the
following
hierarchy,
in
descending
order:
Surface
Water4,
Purchased
Surface
Water,
Ground
Water,
and
Purchased
Ground
Water.
The
presence
of
the
first
source
in
this
list
determines
the
source
assignment
for
that
system.
As
a
result,
all
purchased
ground
water
CWSs
and
nontransient
noncommunity
water
systems
(
NTNCWSs)
are,
by
SDWIS
definition,
100
percent
purchasing
systems.

Unlike
purchased
ground
water
systems,
purchased
surface
water
systems
may
have
nonpurchased
supplies.
To
determine
how
many
purchased
surface
water
CWSs
buy
100
percent
of
their
water,
EPA
reviewed
the
results
of
the
system
linking
exercise
in
section
3.4.2.2.
As
explained
in
that
section,
the
"
linked"
surface
water
system
inventory
was
created
by
adding
the
population
of
100
percent
purchasing
systems
to
their
sellers
and
removing
those
systems
from
the
inventory.
A
system
was
not
"
linked"
to
its
seller
if
it
had
its
own
treatment
plant
or
bought
water
from
a
system
of
a
different
type
(
e.
g.,
a
CWS
buying
water
from
a
NTNCWS).
Thus,
remaining
unlinked
purchased
surface
water
Economic
Analysis

H­

systems
(
shown
in
Exhibit
3.4,
columns
A
and
B)
represent
either
systems
that
purchased
finished
water
and
have
their
own
source,
or
systems
that
buy
from
a
different
system
type.
In
other
words,
those
purchased
surface
water
systems
that
were
able
to
be
linked
represents
the
minimum
number
of
100
percent
purchasing
systems.
Using
the
percentage
of
purchased
systems
that
could
be
linked
to
estimate
100
percent
purchasing
systems
may
create
a
bias
in
the
number
of
estimated
100
percent
purchasing
systems,
but
the
error
introduced
is
expected
to
be
minimal
since
the
number
of
remaining
unlinked
surface
water
CWSs
is
small.

From
Exhibits
3.3
and
3.4,
the
total
number
SDWIS
purchased
surface
water
CWSs
that
could
be
linked
is
5,890
(
4776+
1410­
234­
62),
and
the
percent
of
the
total
is
95
[
5890/(
4776+
1410)].
Note
that
this
calculation
was
not
performed
for
each
Stage
2
DBPR
monitoring
size
category
because
inventory
data
in
Chapter
3
is
organized
according
to
the
standard
nine
size
categories
(
not
the
Stage
2
DBPR
monitoring
categories).
The
percentage
of
all
purchased
surface
water
systems
that
could
be
linked
(
95
percent)
was
used
in
Exhibit
H.
2
to
estimate
the
baseline
number
of
purchased
surface
water
CWSs
that
buy
100
percent
of
their
water
(
see
column
D).

Because
a
large
portion
of
NTNCWSs
could
not
be
linked
because
they
purchase
water
from
different
system
types
(
in
many
cases,
a
NTNCWS
purchases
water
from
a
CWS
and
was
therefore,
not
linked),
a
different
methodology
was
used
to
estimate
the
percent
of
purchased
surface
water
NTNCWS
that
buy
100
percent
of
their
water.
All
NTNCWSs
are
assumed
to
have
just
one
entry
point
per
system
(
as
explained
in
section
3.4.2.2,
these
systems
are
most
often
a
single
building
or
located
in
a
small
area).
Following
this
logic,
a
purchased
surface
water
NTNCWS
is
unlikely
to
have
a
second
treated
source
 
all
are
assumed
to
be
100
percent
purchasing
systems.

Step
3
­
Convert
System
Inventory
to
Plant
Inventory
The
third
step
in
developing
the
Stage
2
DBPR
monitoring
baseline
is
to
estimate
the
baseline
number
of
plants
(
as
noted
earlier
in
this
section,
"
plants"
includes
consecutive
system
entry
points
that
operate
for
at
least
60
consecutive
days).
This
is
needed
because
IDSE
and
compliance
monitoring
requirements
for
producing
systems
are
based
on
the
number
of
plants
per
system.

Column
E
in
Exhibit
H.
2
shows
the
mean
number
of
plants
per
system
for
(
1)
surface
water
and
all
mixed
systems,
and
(
2)
disinfecting
ground
water­
only
systems
that
is
used
to
transform
the
Stage
2
monitoring
system
baseline
to
a
plant
baseline.
These
values
are
based
on
analysis
of
1995
CWSS
data,
question
18.
Note
that
although
they
are
generated
using
the
same
data
set,
the
plant
per
system
values
for
surface
water
and
mixed
systems
in
Exhibit
H.
2
are
different
than
plant
per
system
values
for
primarily
surface
water
systems
in
Exhibit
3.4
(
treatment
plant
baseline).
This
is
because
the
"
primarily
surface
water"
category
used
in
the
treatment
plant
baseline
contains
only
those
mixed
systems
with
more
than
50
percent
of
their
water
from
surface
water
sources.
The
"
surface
water
and
all
mixed"
category
used
for
the
Stage
2
DBPR
monitoring
includes
those
mixed
systems
using
mostly
ground
water.
Mostly
ground
water
systems
typically
have
more
plants
per
system
than
surface
water
systems.
Thus,
mean
plant
per
system
estimates
for
"
surface
water
and
all
mixed"
are
typically
greater
than
for
"
primarily
surface
water
systems.

IDSE
Activities
for
Systems
The
purpose
of
the
IDSE
is
to
aide
PWSs
in
determining
compliance
monitoring
sites
within
their
distribution
systems
for
the
Stage
2B6
DBPR.
Some
systems
are
not
subject
to
IDSE
requirements
or
may
receive
waivers.
The
first
step
in
estimating
costs
for
the
IDSE
is
to
categorize
the
systems
into
one
of
the
five
IDSE
options
listed
below.

Systems
Performing
the
IDSE:

°
Systems
conducting
a
standard
monitoring
program
(
SMP)

°
Systems
using
system­
specific
studies
(
SSS)
Systems
Not
Performing
the
IDSE:

°
All
NTNCWSs
serving
fewer
than
10,000
people
are
not
subject
to
IDSE
requirements.

°
Systems
serving
fewer
than
500
people
with
Stage
1
DBPR
sites
that
represent
both
the
highest
TTHM
and
highest
HAA5
can
receive
a
very
small
system
waiver.

°
Systems
with
all
TTHM
and
HAA5
data
less
than
or
equal
to
40/
30
µ
g/
L,
respectively,
during
the
two
years
prior
to
the
start
of
the
IDSE
can
qualify
for
the
40/
30
certification.

Costs
and
burden
associated
with
IDSE
activities
differ
depending
on
whether
or
not
the
system
performs
the
IDSE
and,
if
so,
which
option
a
system
chooses.
All
systems
performing
the
IDSE
are
expected
to
incur
some
costs.

Section
H.
3.1
describes
the
assumptions
for
allocating
systems
to
the
five
categories.
Section
H.
3.2
provides
cost
estimates
for
those
systems
performing
the
IDSE
(
SMP
or
SSS
option).
Section
H.
3.3
provides
the
rationale
and,
if
appropriate,
cost
estimates
for
systems
not
performing
the
IDSE
(
NTNCWSs
serving
<
10,000;
systems
serving
<
500
that
receive
a
waiver;
and
systems
that
qualify
for
the
40/
30
certification).

H.
3.1
Categorization
of
Systems
Exhibits
H.
4a
and
H.
4b
summarize
the
percentages
and
estimated
number
of
systems
that
will
conduct
each
IDSE
activity
for
100
percent
purchasing
systems
and
producing
systems,
respectively.
The
percentages
associated
with
each
IDSE
activity
have
been
derived
for
the
total
population
of
systems
in
each
size
category,
but
are
applied
to
the
number
of
systems
in
a
size
category
sequentially.
First,
the
small
systems
waiver
is
applied
to
the
total
number
of
systems;
then
the
percentage
of
systems
qualifying
for
the
40/
30
certification
is
applied
to
the
remaining
systems;
finally,
the
percentage
of
systems
Economic
Analysis
for
Stage
2
DBPR
Proposal
H­
10
July
2003
conducting
a
SSS
is
applied
to
the
systems
that
cannot
be
granted
either
the
waiver
or
certification.
The
reason
the
percentages
are
applied
sequentially
is
that
each
individual
system
will
only
select
one
option.
For
example,
if
they
are
able
to
receive
the
small
system
waiver
they
will
not
seek
the
40/
30
certification,
even
though
they
may
qualify
for
it.
Therefore
the
sub
population
of
systems
receiving
the
waiver
is
subtracted
from
the
total
population.
The
assumptions
underlying
the
percentages
are
discussed
in
detail
in
the
remainder
of
this
section.
Total
numbers
of
systems
for
the
IDSE
categories
expected
to
result
in
system
costs
(
SMP,
SSS,
and
40/
30
certification)
are
presented
in
the
last
three
columns
of
the
exhibits.
Note
that
the
results
in
Exhibit
H.
4a
and
H.
4b
are
rounded
to
whole
systems.

NTNCWSs
Serving
<
10,000
People
None
of
the
NTNCWSs
serving
fewer
than
10,000
people
are
subject
to
the
IDSE
requirements.
The
exhibits
in
this
appendix
note
"
N/
A"
for
these
NTNCWS
population
categories.

Systems
Receiving
a
Very
Small
System
Waiver
Systems
serving
fewer
than
500
people
may
receive
a
very
small
system
waiver
from
the
IDSE
requirements.
For
a
system
to
qualify,
the
State/
Primacy
Agency
must
determine
that
the
monitoring
site
approved
for
Stage
1
DBPR
compliance
is
sufficient
to
represent
both
the
highest
TTHM
and
the
highest
HAA5
concentrations
within
the
distribution
system.
EPA
estimates
that
75
percent
of
these
small
systems
will
be
able
to
receive
a
very
small
system
waiver.

Systems
Qualifying
for
the
40/
30
Certification
EPA
used
various
data
sources
to
estimate
the
percentage
of
systems
that
could
potentially
qualify
for
40/
30
certification.
Based
on
analysis
of
Information
Collection
Rule
(
ICR)
data,
it
was
estimated
that
14
percent
of
large
and
medium
surface
water
systems
could
show
that
all
compliance
monitoring
data
were
less
than
or
equal
to
40
µ
g/
L
for
TTHM
and
30
µ
g/
L
for
HAA5.
EPA
believes
this
may
be
an
underestimate
because
it
is
based
on
pre­
Stage
1
data
(
systems
may
make
changes
to
meet
Stage
1
requirements
that
will
result
in
all
of
their
samples
being
less
than
or
equal
to
40/
30).
In
the
absence
of
other
information,
however,
EPA
believes
that
14
percent
is
the
best
estimate
of
large
and
medium
surface
water
systems
that
could
meet
the
40/
30
certification
requirements.

For
small
surface
water
systems,
analysis
of
National
Rural
Water
Association
(
NRWA)
Winter
and
Summer
data
indicates
that
12
percent
could
qualify
for
the
40/
30
certification.
However,
small
systems
have
a
later
start
date
for
the
IDSE,
and
some
systems
will
most
likely
make
treatment
changes
to
meet
the
Stage
1
DBPR
before
the
start
of
the
IDSE.
Therefore,
the
percent
with
all
compliance
data
less
than
or
equal
to
40/
30
for
small
systems
is
estimated
to
be
the
same
as
large
systems
at
14
percent.

For
all
ground
water
systems,
ICR
data
were
used
to
estimate
the
percentage
that
could
qualify
for
the
40/
30
certification.
Approximately
24
percent
of
ICR
ground
water
systems
are
located
in
Florida
where
total
organic
carbon
(
TOC)
levels
(
and
consequently
disinfection
byproduct
[
DBP]
levels)
are
high.
Appendix
B
describes
the
analysis
of
Florida
and
non­
Florida
ICR
data,
which
shows
that
18
percent
of
Florida
systems
have
all
data
less
than
or
equal
to
40/
30
and
92
percent
of
non­
Florida
systems
have
all
data
less
than
or
equal
to
40/
30.
These
percentages
were
applied
to
the
Florida
and
non­
Florida
systems
in
each
system
size
category,
respectively
to
produce
the
percent
estimates
in

H­

The
estimated
percentage
of
100
percent
purchasing
surface
water
systems
serving
less
than
10,000
people
that
could
qualify
for
the
40/
30
certification
has
been
adjusted
to
account
for
changes
from
Stage
1
to
Stage
2
monitoring
requirements.
The
Stage
1
DBPR
monitoring
requirements
for
100
percent
purchasing
systems
were
left
to
the
State/
Primacy
Agency
to
determine,
allowing
them
to
develop
a
monitoring
plan
with
consideration
of
the
combined
distribution
system.
It
is
possible
that
some
smaller
systems
do
not
have
any
Stage
1
monitoring
sites
in
their
distribution
system
and,
therefore,
have
no
data
to
support
the
40/
30
certification.
To
account
for
this
situation,
the
estimated
percentage
below
40/
30
was
decreased
for
100
percent
purchasing
surface
water
systems
serving
less
than
10,000
people.
EPA
assumed
that
the
40/
30
certification
would
not
be
possible
for
100
percent
purchasing
systems
serving
less
than
10,000
people
that
purchase
water
from
systems
serving
more
than
10,000
people
(
the
percentage
of
purchased
systems
serving
<
10,000
that
buy
from
systems
serving
>
10,000
was
obtained
from
the
Geometries
and
Characteristics
for
Public
Water
Systems
[
USEPA
2000c]).
EPA
believes
this
results
in
a
low
estimate
of
the
systems
that
could
qualify
for
the
certification,
meaning
it
is
likely
that
more
systems
will
be
able
to
meet
the
40/
30
certification
criteria
than
accounted
for
in
the
IDSE
cost
calculations.

Conducting
an
SSS
An
SSS
can
be
used
instead
of
an
SMP
if
the
system
can
show
that
an
SSS
provides
equivalent
or
superior
Stage
2B
site
selection.
An
SSS
can
be
based
on
hydraulic
modeling
results
and
historical
data,
among
other
things.
EPA
estimates
that
10
percent
of
the
surface
water
and
disinfecting
ground
water
systems
serving
more
than
100,000
people
and
5
percent
of
surface
water
systems
serving
50,000
to
100,000
people
will
be
able
to
complete
an
SSS
in
lieu
of
monitoring.
It
is
assumed
that
surface
water
systems
serving
fewer
than
50,000
people
and
ground
water
systems
serving
fewer
than
100,000
people
will
not
have
adequate
historical
data
or
models
to
meet
the
SSS
requirements.

Conducting
an
SMP
All
systems
that
do
not
receive
a
waiver,
do
not
qualify
for
the
40/
30
certification,
or
cannot
use
an
SSS
are
required
to
perform
the
SMP.
The
SMP
involves
selecting
specific
types
of
sample
sites
in
the
distribution
system
(
e.
g.,
maximum
TTHM
sites,
sites
near
the
entry
point)
and
monitoring
at
those
sites
for
1
year.
The
number
and
type
of
required
samples
are
based
on
system
size,
the
number
of
plants
in
the
system
(
for
producing
systems),
source
water
type,
and
residual
disinfectant
type.
The
system
must
prepare
a
report
summarizing
the
results
of
the
SMP
and
justifying
selection
of
Stage
2B
compliance
monitoring
sites.

H.
3.2
Costs
for
Systems
Performing
the
IDSE
Systems
Conducting
the
SMP
An
SMP
consists
of
three
activities
 
site
selection,
monitoring,
and
reporting.
Costs
associated
with
site
selection
result
from
the
labor
effort
required
to
evaluate
the
distribution
system
and
select
the
sites.
Labor
hours
are
estimated
on
a
per­
system
basis
and
vary
by
system
size,
with
the
assumption
that
larger
systems
need
more
time
to
select
sites.
The
labor
hour
estimates
for
site
selection
are
based
on
expert
opinion
and
experience
with
other
rules.

Monitoring
costs
include
labor
for
sample
collection
and
laboratory
costs
for
sample
analysis.
These
costs
are
estimated
from
the
number
of
samples
required.
EPA
estimates
an
average
of
one
hour
Economic
Analysis
for
Stage
2
DBPR
Proposal
H­
14
July
2003
to
collect
one
sample.
Laboratory
costs
include
$
200
for
analysis
of
TTHM
and
HAA5
paired
samples
and
$
20
in
delivery
charges.
These
costs
represent
averages
obtained
from
the
ICR
(
see
Chapter
6,
section
6.1.1
for
more
information
on
laboratory
cost
assumptions).
Costs
per
sample
for
ground
and
surface
water
plants
are
not
expected
to
differ
substantially.

As
noted
in
section
H.
1,
the
total
number
of
sampling
sites
and
frequency
of
sampling
for
100
percent
purchasing
systems
is
a
function
of
system
size
(
population
served)
and
source
water
type,
not
the
number
of
plants.
For
producing
systems,
the
total
number
of
sampling
sites
is
a
function
of
system
size,
source
water
type,
and
the
number
of
plants
in
the
system.
The
frequency
of
sampling
is
a
function
of
the
system
size
and
source
water
type.
For
both
100
percent
purchasing
and
producing
systems,
larger
systems
must
sample
at
more
sites
and
more
frequently
than
smaller
ones,
which
typically
have
shorter
and
less
complex
distribution
systems.
Surface
water
sources
generally
have
higher
DBP
precursor
levels
than
ground
water
sources;
therefore,
they
have
a
greater
potential
for
high
DBP
occurrence.

Reporting
costs
reflect
the
labor
required
for
systems
to
prepare
and
submit
a
report
to
their
State/
Primacy
Agency
on
IDSE
results
and
their
proposed
Stage
2B
DBPR
compliance
monitoring
sites.
These
costs
are
estimated
on
a
per­
system
basis
for
all
systems.
The
reporting
labor
rate
is
the
same
rate
that
is
used
for
site
selection.

Exhibits
H.
5a
and
H.
5b
show
the
calculations
and
estimated
costs
and
burden
for
100
percent
purchasing
and
producing
systems,
respectively,
expected
to
monitor
for
the
IDSE.

Systems
That
Perform
an
SSS
Cost
estimates
for
systems
conducting
an
SSS
consist
only
of
system­
level
reporting
costs.
These
reporting
costs
are
associated
with
activities
that
include
gathering,
researching,
and
analyzing
distribution
system
information.
As
a
result,
EPA
estimates
that
more
reporting
labor
hours
will
be
required
than
would
be
required
only
to
report
the
results
of
monitoring
(
as
presented
in
Exhibits
H.
5a
and
H.
5b).

H.
3.3
Costs
for
Systems
Not
Performing
the
IDSE
As
noted
in
the
beginning
of
section
H.
3,
there
are
three
types
of
systems
that
do
not
have
to
perform
the
IDSE:

°
All
NTNCWSs
serving
fewer
than
10,000
people
(
they
are
not
subject
to
IDSE
requirements)

°
Systems
receiving
the
very
small
system
waiver
(
States/
Primacy
Agencies
can
grant
this
waiver
if
they
determine
that
a
system's
high
TTHM
and
HAA5
concentrations
can
be
represented
by
one
site)

°
Systems
qualifying
for
the
40/
30
certification
(
all
TTHM
and
HAA5
compliance
monitoring
data
must
be
less
than
or
equal
to
40/
30
µ
g/
L,
respectively)

Since
NTNCWSs
serving
fewer
than
10,000
people
are
not
subject
to
IDSE
requirements,
they
are
assumed
to
bear
no
costs.
EPA
estimates
a
minimal
burden
for
systems
to
obtain
a
very
small
system
waiver
from
their
State/
Primacy
Agency,
given
this
activity
is
considered
to
be
part
of
their
routine
communication.
Therefore,
this
EA
does
not
include
costs
for
systems
getting
the
very
small
system
waiver.

Systems
qualifying
for
40/
30
certification
are
expected
to
bear
some
costs
for
the
IDSE
since
they
must
submit
a
report
with
their
TTHM/
HAA5
monitoring
results
and
a
schematic
of
their
distribution
system
with
the
results,
locations,
and
date
of
all
compliance
samples
noted.
Cost
calculations
are
shown
in
Exhibit
H.
7a
and
H.
7b.
Because
some
components
of
IDSE
reports
for
40/
30
certification
and
for
SMPs
are
similar,
the
labor
cost
to
prepare
a
report
for
40/
30
certification
was
estimated
to
be
some
fraction
of
the
labor
cost
estimate
for
preparing
the
IDSE
report
for
systems
performing
monitoring
(
see
section
H.
3.2
for
a
derivation
of
costs
for
the
IDSE
SMP).
Reporting
hours
for
the
IDSE
SMP
are
in
Exhibit
H.
5a,
column
G
for
100
percent
purchasing
systems
and
Exhibit
H.
5b,
column
H
for
producing
systems.
For
systems
serving
fewer
than
10,000
people,
reporting
hours
for
40/
30
certification
reports
were
estimated
to
be
half
(
50
percent)
of
the
reporting
hours
for
IDSE
SMPs.
For
systems
serving
at
least
10,000
people,
reporting
hours
for
40/
30
certification
were
estimated
to
be
one
quarter
(
25
percent)
of
the
reporting
hours
for
IDSE
SMPs.
Resulting
reporting
hours
for
systems
qualifying
for
40/
30
certification
are
shown
in
column
D
of
Exhibit
H.
7a
and
column
B
of
Exhibit
H.
7b
EPA
also
considers
costs
for
those
systems
that
qualify
for
the
40/
30
certification
and
do
not
have
to
perform
the
IDSE,
but
must
select
additional
Stage
2B
sites
compared
to
Stage
1
DBPR
requirements.
Producing
systems
not
performing
the
IDSE
have
the
option
of
maintaining
their
Stage
1
DBPR
site
locations
as
their
Stage
2B
sites.
Therefore,
EPA
does
not
attribute
site­
selection
costs
for
producing
systems
that
qualify
for
the
40/
30
certification.
There
are
changes,
however,
in
site
requirements
for
100
percent
purchasing
systems
from
Stage
1
to
Stage
2B
because
of
the
change
from
plant­
to
population­
based
monitoring
requirements.
Some
100
percent
purchasing
systems
are
predicted
to
show
a
reduction
in
the
required
number
of
sites
from
Stage
1
to
Stage
2B,
but
many
are
predicted
to
add
sites.
Exhibit
H.
7a
shows
EPA's
estimated
site­
selection
costs
and
burden
for
100
percent
purchasing
systems
that
qualify
for
the
40/
30
certification
and
do
not
conduct
the
IDSE,
but
are
predicted
to
add
sample
sites
for
the
Stage
2B
DBPR
(
see
section
H.
4
for
estimates
of
100

Additional
Routine
Monitoring
Costs
for
Systems
This
section
presents
the
costs
for
systems
to
perform
additional
routine
monitoring
associated
with
the
Stage
2B
DBPR.
The
additional
routine
monitoring
cost
estimates
are
dependent
on
the
change
in
the
number
of
samples
to
be
collected
from
the
Stage
1
to
the
Stage
2B
DBPR.

100
Percent
Purchasing
Systems
The
Stage
2B
DBPR
monitoring
requirements
for
100
percent
purchasing
systems
are
based
only
on
population
served
and
source
water
type,
while
the
Stage
1
DBPR
requirements
are
also
based
on
the
number
of
treatment
plants.
With
this
modification
in
monitoring
scheme,
the
number
of
samples
required
is
estimated
to
decrease
from
the
Stage
1
to
the
Stage
2
DBPR
for
many
systems.
Exhibit
H.
8a
summarizes
the
estimated
change
in
number
of
samples
required
and
the
associated
cost.
An
explanation
of
this
exhibit
is
provided
in
the
following
paragraphs.

Columns
E
and
I
show
the
number
of
Stage
2B
DBPR
routine
samples
per
system
required
for
100
percent
purchasing
systems.
For
surface
water
systems
serving
less
than
5,000
people
and
disinfecting
ground
water
systems
serving
less
than
500
people,
two
sites
per
system
are
required,
one
representing
the
high
TTHM
and
the
other
representing
the
high
HAA5
site.
(
Note
that
for
surface
water
systems
serving
500
to
4,999
people,
samples
must
be
collected
every
90
days,
resulting
in
a
total
of
8
samples
per
system.
Surface
and
ground
water
systems
serving
less
than
500
people
only
have
to
collect
one
sample
per
year,
resulting
in
two
samples
per
system
as
shown
in
Exhibit
H.
8a).
The
Stage
2
DBPR
allows
these
systems
to
use
one
instead
of
two
sites
if
it
represents
both
the
high
TTHM
and
high
HAA5
location.

The
percent
of
systems
that
can
use
one
monitoring
site
(
instead
of
2)
to
represent
both
high
TTHM
and
high
HAA5
concentrations
is
estimated
separately
for
those
that
perform
the
IDSE
and
those
that
do
not.
This
is
because
systems
that
conduct
the
IDSE
will
have
TTHM
and
HAA5
data,
while
those
that
do
not
conduct
the
IDSE
will
not
have
DBP
data
and
will
have
to
rely
on
an
indicator.
For
100
percent
purchasing
CWSs
that
perform
the
IDSE,
EPA
evaluated
data
from
the
last
four
quarters
of
the
ICR
to
estimate
the
percentage
of
systems
that
had
their
highest
TTHM
and
HAA5
at
the
same
location7
and
thus,
qualify
for
only
one
site
and
half
the
number
of
samples
per
year
shown
in
Exhibit
H.
8a.
Results
of
this
analysis
show
that
approximately
56
percent
of
surface
water
and
46
percent
of
ground
water
plants
have
their
high
TTHM
and
HAA5
sites
at
the
same
location
and
will
collect
half
the
maximum
possible
number
of
samples
required.

For
100
percent
purchasing
CWSs
not
performing
the
IDSE,
the
percentage
of
systems
qualifying
for
reduced
monitoring
can
be
estimated
using
disinfectant
residual
data.
This
is
because
conditions
of
low
or
no
disinfectant
residual
could
lead
to
biological
degradation
of
HAA5
concentrations
(
Singer
and
Reckhow
1999).
Thus,
the
maximum
HAA5
site
might
be
closer
to
the
treatment
plant
if
there
are
sites
with
no
or
low
residual.

H­
25

ICR
and
NRWA
data
were
evaluated
to
assess
the
portion
of
systems
that
did
not
report
a
detectable
disinfectant
residual
at
all
sample
locations.
The
data
showed
that
approximately
25
percent
of
small
surface
water
plants
(
based
on
NRWA
data),
and
35
percent
of
large
ground
water
plants
(
based
on
ICR
data)
reported
no
or
low
residual
at
one
or
more
of
their
distribution
sample
sites
(
meaning
75
and
65
percent
of
surface
and
ground
water
systems
could
potentially
collect
half
the
number
of
samples,
as
shown
in
column
J
of
Exhibit
H.
8a).

For
100
percent
purchasing
NTNCWSs,
high
TTHM
and
HAA5
concentrations
are
more
likely
to
be
at
the
same
location
because
these
systems
are
typically
small
and
have
small
distribution
systems.
Thus,
EPA
believes
that
all
eligible
NTNCWSs
(
surface
water
NTNCWSs
serving
less
than
10,000
people
and
ground
water
NTNCWSs
serving
less
than
500
people)
will
qualify
for
reduced
monitoring
site
requirements.

Producing
Systems
The
Stage
2B
DBPR
monitoring
requirements
for
producing
systems
are
based
on
the
same
criteria
(
source
water
type,
population
served,
and
number
of
treatment
plants)
as
the
Stage
1
DBPR.
Most
systems
will
be
required
to
collect
the
same
number
of
samples
as
under
the
Stage
1
DBPR
and,
thus,
will
incur
no
additional
costs.
The
following
systems

Exhibit
H.
8b
summarizes
the
estimated
change
in
the
number
of
samples
required
and
the
associated
cost.
An
explanation
of
this
exhibit
is
provided
in
the
following
paragraphs.

Like
100
percent
purchasing
systems,
EPA
estimated
the
percentage
of
systems
that
would
have
to
add
a
site
separately
for
those
that
perform
the
IDSE
and
those
that
do
not
(
this
is
because
small
systems
that
conduct
the
IDSE
will
have
TTHM
and
HAA5
data,
while
those
that
do
not
conduct
the
IDSE
will
not
have
DBP
data
and
will
have
to
rely
on
an
indicator).
The
derivation
of
the
percentage
of
systems
with
their
high
TTHM
and
HAA5
at
different
locations
is
the
same
as
for
the
100
percent
purchasing
system
analysis,
resulting
in
the
following:

°
For
CWSs
conducting
the
IDSE,
44
percent
of
surface
water
and
54
percent
of
ground
water
systems
will
have
to
add
a
site
because
their
high
TTHM
and
HAA5
concentrations
occur
at
different
locations
based
on
evaluation
of
ICR
data.
(
See
footnote
7
on
page
H­
22.)

°
For
CWSs
not
performing
the
IDSE,
25
percent
of
surface
water
and
35
percent
of
ground
water
systems
will
have
to
add
a
site
because
their
high
TTHM
and
HAA5
concentrations
occur
at
different
locations
based
on
evaluation
of
NRWA
and
ICR
disinfectant
residual
data.

°
For
NTNCWSs
serving
less
than
10,000
people,
all
systems
are
likely
to
have
high
TTHM
and
HAA5
concentrations
at
the
same
location
because
NTNCWSs
are
typically
small
and
have
small
distribution
systems.

results
are
below

will
be
able
to
meet
the
criteria

Although
the

is
expected
to
be
reduced
by
the
Stage

EPA
recognizes
that
excursions
above
80

and
60
:
g/
L
for
HAA5
may
still
occur,

In
the
rule,
EPA
has
not
included
specific
criteria
that
systems
must
use
for
initiating
a
significant
excursion
evaluation.
However,
the
draft
guidance
includes
a
number
of
options
that
States/
Primacy
Agencies
may
use
to
determine
that
a
significant
excursion
has
occurred.
If
a
significant
excursion
occurs,
the
system
is
required
to
conduct
a
significant
excursion
evaluation.
For
purposes
of
costing
in
the
primary
cost
analysis,
EPA
has
used
one
of
the
options
to
develop
compliance
costs
and
burdens.
The
option
selected
for
the
primary

analysis
assumes
that
systems
will
conduct
a
significant

evaluation
if
a

exceeds
either
a

System
Requirements
for
Significant
Excursions
If
a
significant
excursion
occurs,
systems
must
conduct
a
significant
excursion
evaluation
and
discuss
the
evaluation
with
the
State/
Primacy
Agency
no
later
than
the
next
sanitary
survey.
A
significant
excursion
evaluation
must
include
an
examination
of
distribution
system
operational
practices
and
how
these
practices
may
be
modified
to
reduce
TTHM
and
HAA5
levels.

A
significant
excursion,
as
defined
in
section
H.
5.1,
is
not
a
violation
of
the
Stage
2
DBPR
and
does
not
require
any
public
notification
or
explanation
in
Consumer
Confidence
Reports
(
CCR).

Cost
Implications
of
Significant
Excursions
Each
significant
excursion
event
is
expected
to
result
in
some
labor
costs
for
systems
to
evaluate
the
excursion
and
document
its
cause.
To
determine
national
costs
for
significant
excursion
evaluations,
this

presents
an
estimate
of:
(
1)
the
percent
of
all

that
are
significant

and
(

the

for
each

The
methodology
for
predicting
the
percent
of
samples
exceeding
100
µ
g/
L
for
TTHM
or
75
µ
g/
L
for
HAA5
for
large
systems
is
similar
to
the
methodology
for
predicting
occurrence
of
peak
DBPs
following
the
Stage
2
DBPR,
as
described
in
section
5.4.1.
Predicted
occurrence
of
TTHM
and
HAA5
peaks
were
based
on
ICR
distribution
system
sampling
results
from
January
1998
through
December
1998.
Four
distribution
system
sampling
locations
were
evaluated:
DSE,
AVG1,
AVG2,
and
DS
maximum
(
see
Chapter
3,
section
3.7.1,
for
a
description
of
these
sampling
locations).
ICR
plants
were
first
screened
to
ensure
that
they
met
minimum
data
criteria,
8
then
evaluated
for
compliance
with
Stage
2B
DBPR
MCLs,
given
a
20
percent
safety
factor
(
64
and
48
:
g/
L
for
TTHM
and
HAA5,
respectively).
A
total
of
136
surface
water
plants
and
75
ground
water
plants
met
the
screening
criteria
and
were
found
to
be
compliance
with
the
Stage
2B
DBPR.

Exhibit
H.
9
shows
the
results
of
the
ICR
analysis,
which
include
the
total
number
of
samples,
plants,
and
systems
evaluated
and
the
percent
of
each
exceeding
a
TTHM
level
of
100
:
g/

an
HAA5
level
of
75

g/
L,
or
both.

The
results
in
H.
9
based
on
ICR
data
are
assumed
to
adequately
represent
the
percent
of
samples
that
are
peaks
for
large
CWSs
serving
100,000
or
more
people.
For
medium
CWSs
serving
10,000
to
99,999
people,
the
percent
of
samples
that
are
peaks
is
estimated
to
be
the
same
as
that
for
large
systems.
This
is
because
medium
systems
have
similar
source
water
quality,
disinfectant
use,
and
distribution
system
TTHM
and
HAA5
concentrations
as
large
systems
(
see
Appendix
A
for

water
system
data).
For
small

and
mixed
CWSs
serving
500
to
9,999
people,
the
estimated
incidence
of
peaks
for
large
systems
(
0.3%
of
all
samples)
is
used.
The
occurrence
of

to

Predicted
Occurrence
of
Significant
Excursions
in
Large
Systems
To
estimate
the
percent
of
systems
experiencing
at
least
one
peak
per
year,
EPA
first
considered
using
ICR
data
from
the
last
column
in
Exhibit
H.
9.
However,
the
data
was
not
applicable
to
all
systems
for
two
reasons.
First,
the
ICR
dataset
has
roughly
20
samples
per
system
on
average.
Sampling
requirements
for
the
Stage
2B
DBPR
vary
from
as
little
as
1
per
year
to
96
samples
per
year.
Using
the
ICR
data
would
overestimate
the
number
of
systems
for
systems
with
fewer
than
20
samples
per
year
and
underestimate
the
number
of
systems
with
more
than
20
samples
per
year.
Second,
the
usable
subset
of
ICR
data
only
contains
97
surface
water
systems
and
57
ground
water
systems
currently
meeting
Stage
2
requirements.
This
is
a
small
sample
size
from
which
to
extrapolate
to
all
CWSs
with
varying
numbers
of
sample
per
year
requirements.

To
overcome
these
limitations
but
still
make
use
of
the
ICR
data
to
estimate
peak
occurrences,
EPA
has
assumed
that
the
full
data
set
of
1,975
surface
water
samples
and
the
1,087
ground
water
samples
are
representative
as
a
whole
of
probability
that
any
one
sample
in
treated
water
meeting
the
Stage
2
requirements
will
be
a
peak.
Those
single
sample
probabilities
are
0.3%
(
6/
1,975)
and
0%
(
0/
1,087)
for
surface
water
and
ground
water
systems,
respectively.
To
calculate
the
probability
of
finding
a
peak
in
a
year
given
that
plants
take
multiple
samples,
the
following
procedure
was
used.
Assuming
independence
from
one
sample
to
the
next,
one
can
calculate
the
probability
of
at
least
one
peak
occurring
for
N
samples
from
1­(
1­
p)
N,
where
p
is
the
probability
of
observing
a
peak.
In
this
calculation,
(
1­
p)
is
the
probability
of
not
observing
a
peak
in
any
one
sample,
and
(
1­
p)
N
is
the
probability
of
not
observing
a
peak
after
N
samples.
For
example,
it
can
be
estimated
that
a
surface
water
plant
taking
16
samples
has
a
probability
of
(
1­
0.003)
16
=
0.9531
of
not
observing
a
peak
in
those
16
samples.
Therefore,
the
probability
of
observing
at
least
one
peak
when
16
samples
are
taken
is
simply
1
minus
that
value,
or
1
­
0.9531
=
0.0469
(
4.69%).
This
approach
was
used
to
estimate
the
probability
of
observing
a
peak
in
surface
and
ground
water
plants
and
systems
(
using
plant
per
system
data
where
appropriate)
as
displayed
in

and

Level
of
Effort
Required
for
Significant
Excursion
Evaluations
EPA
estimates
that
systems
will
spend
1
to
2
hours
to
perform
a
significant
excursion
evaluation,
depending
on
system
size
(
large
systems
with
more
complex
distribution
systems
are
expected
to
spend
2
hours
per
excursion,
while
small
systems
with
simpler
distribution
systems
are
expected
to
spend
1
hour
per
excursion).
There
may
be
reduced
effort
for
systems
that
experience
more
than
one
significant
excursion
yearly;
however,
this
effect
could
not
be
quantified.
EPA
also
expects
the
rate
of
excursions
to
decrease
over
time
as
systems
begin
identifying
the
cause
and
working
with
their
States/
Primacy
Agencies
to
reduce
future
excursions.

Cost
Summary
The
total
costs
for
significant
excursion
evaluations
are
summarized
in
Exhibits
H.
11a
and
H.
11b
for
100
percent
purchasing
and
producing
systems,
respectively.
Note
that
the
burden
to
systems
is
very
small
($
16,820).
EPA
assumes
that
review
of
significant
DBP
excursion
evaluations
will
occur
as
part
of
the
normal
review
process
during
the
sanitary
survey
and
allocates
no
additional
cost
to
systems
or
States/
Primacy
Agencies
for
this
activity.

Other
Cost
Implications
Although
systems
are
not
required
to
make
changes
as
a
result
of
significant
DBP
excursions,
they
may
still
decide
to
change
their
operations
to
reduce
the
likelihood
of
future
significant
excursions
and
potential
MCL
violations.
These
changes
can
range
from
minimal
to
significant
depending
on
the
nature
of
the
solution
and
size
of
the
system.
Because
changes
are
not
required
by
EPA,
the
costs
for
responding
to
significant
excursions
are
not
included
as
part
of
the
national
costs
of
the
Stage
2
DBPR;
however,
examples
of
typical
system­
level
costs
are
provided
below
to
show
potential
implications.

Systems
have
a
number
of
operational
and
distribution
system
modification
options
available
to
reduce
DBP
concentrations
and
eliminate
significant
excursions.
These
include
low­
cost
options,
such
as
longer
or
more
frequent
drain/
fill
cycles
to
improve
storage
tank
turnover
and
mixing,
as
well
as
more
expensive
options
involving
distribution
system
looping
and
inlet/
outlet
piping
modifications
to
storage
tanks.
Where
possible,
it
is
expected
that
systems
would
first
choose
a
low­
cost
option
to
reduce
peak
DBP
concentrations.

If
a
system
determines
that
a
storage
tank
is
the
cause
of
an
excursion,
it
may
be
possible
to
implement
operational
changes,
such
as
lengthening
drain/
fill
cycles
or
increasing
the
frequency
of
drain/
fill
cycles,
to
improve
tank
mixing.
A
system
may
also
consider
decommissioning
excess
storage,
or
maintaining
excess
storage
for
emergency
use
only.
Generally,
these
options
will
require
minimal
additional
expenditures
by
the
system;
however,
in
some
cases
their
feasibility
may
depend
on
system
pressure
requirements.
When
excess
storage
is
to
be
maintained
for
emergency
use
only,
it
is
still
important
to
maintain
water
quality
in
the
storage
tank.
This
may
require
periodic
manual
disinfection
(
i.
e.,
addition
of
calcium
hypochlorite
tablets)
to
prevent
significant
microbiological
activity
in
the
storage
tank.
This
can
involve
some
chemical
cost
(
chlorination
tablets
are
available
for
about
$
65
per
25
pounds),
as
well
as
additional
labor
cost
(
e.
g.,
a
few
hours
for
a
two­
person
crew).
When
excess
storage
is
to
be
maintained
for
emergency
use
only,
it
is
important
to
adequately
flush
the
system
after
the
tank
has
been
used.

For
the
purposes
of
deterimining
the
frequency
of
occurrence
of
significant
excursions
and
associated
cost
and
burden,
EPA
used
the
assumptions
discussed
in
section
H.
5.1
(
i.
e.,
systems
will
conduct
a
significant
excursion
if
a
Stage
2B
compliance
sample
exceeds
either
a
TTHM
concentration
of
100
ug/
L
or
an
HAA5
concentration
of
75
ug/
L).
This
is
only
one
of
several
options
­
if
a
different
option
were
selected,
the
number
of
systems
with
significant
excursions
would
vary.

Significant

Costs

Economic
Analysis
for
Stage
2
DBPR
Proposal
H­
36
July
2003
If
a
system
determines
that
the
source
of
a
significant
DBP
excursion
is
a
storage
tank
and
is
unable
to
improve
tank
water
quality
using
operational
modifications
(
i.
e.,
changes
in
drain/
fill
patterns),
then
it
may
be
necessary
to
make
inlet/
outlet
piping
modifications,
install
baffles,
or
add
a
recirculation
system
to
improve
tank
mixing.
The
costs
for
these
types
of
improvements
are
widely
variable
and
depend
on
the
size
and
configuration
of
the
existing
tank.
For
example,
capital
costs
for
modifications
to
inlet/
outlet
piping
in
six
standpipes
(
2
million
gallon
(
MG)
to
4
MG
capacity)
may
range
from
$
78,000
to
$
94,000
for
one
system.
Costs
for
modifications
to
elevated
tanks
(
all
1
MG
capacity)
may
range
from
$
19,000
to
$
90,000
for
the
same
system.
These
costs
do
not
include
the
installation
of
sample
probes
and
temperature
sensors
(
estimated
at
$
34,000
per
tank
including
tie­
in
to
an
existing
Supervisory
Control
and
Data
Acquisition
(
SCADA)
system)
used
to
verify
proper
tank
mixing.

Another
operational
option
available
to
systems
is
the
use
of
flushing
and
blow­
offs
in
highresidence
time
areas.
Costs
for
these
options
can
vary
significantly
from
system
to
system
depending
on
size,
amount
of
labor
involved,
and
if
system
modifications
are
required.
Some
large
systems
employ
one
or
more
flushing
crews,
whose
sole
responsibility
is
to
flush
system
dead
ends.
For
a
two­
person
crew
at
a
labor
rate
of
$
25
per
hour
(
including
fringe
benefits),
a
system
would
incur
a
cost
of
over
$
100,000
per
year.
Assuming
installation
of
a
fire
hydrant
as
a
conservative
estimate,
the
cost
to
add
a
dead
end
blowoff
or
flushing
station
could
be
$
8,000
or
more
(
RS
Means
1999).
Where
runoff
from
blow­
offs
or
flushing
locations
contains
chloramines
and
may
enter
open
waterways,
neutralization
of
chloraminated
discharges
will
be
necessary.
This
can
be
done
by
laying
burlap
sacks
filled
with
ammonium
sulfate
or
sodium
sulfite
in
the
path
of
the
runoff.
Ammonium
sulfate
is
available
for
about
$
0.35
per
pound
and
sodium
sulfite
can
be
purchased
for
about
$
0.50
per
pound.
Water
losses
may
also
be
a
concern
in
water
scarce
regions.
The
costs
associated
with
water
losses
are
system­
specific
and
no
attempt
has
been
made
to
quantify
these
costs
here.

If
long
residence
times
in
distribution
system
dead
ends
are
the
source
of
a
significant
excursion,
then
systems
may
be
able
to
improve
flow
in
dead­
end
areas
and
reduce
water
residence
time
by
"
looping"
dead
ends
together.
For
looping
to
be
effective,
it
is
critical
that
sufficient
demand
exists
in
the
looped
area
to
create
a
flow
pattern
that
eliminates
the
dead
end,
rather
than
creating
a
larger
one.
The
costs
associated
with
looping
will
vary
from
system
to
system,
depending
on
the
size
and
length
of
pipe
involved.
Based
on
cost
data
presented
in
RS
Means
(
1999),
the
cost
for
looping
may
range
from
$
3,500
per
100
feet
for
a
6­
inch
line
to
$
20,000
per
100
feet
for
a
24­
inch
line.

Variability
from
system
to
system
makes
it
difficult
to
quantify
the
possible
costs
associated
with
significant
excursion
remedies.
The
most
effective
option
will
vary
from
system
to
system,
as
will
the
costs
for
similar
types
of
improvements.

H.
5.4
Benefits
Implications
of
the
Significant
Excursion
Requirements
As
discussed
in
detail
in
Chapter
5
of
this
EA,
a
primary
objective
of
the
Stage
2
DBPR
is
to
reduce
peak
DBP
occurrence,
thereby
reducing
potential
adverse
developmental
and
reproductive
health
effects
and
cancers
associated
with
DBPs.
Although
systems
are
not
required
to
make
changes
in
response
to
significant
DBP
excursions,
EPA
believes
that
the
requirement
to
perform
a
significant
excursion
evaluation
and
review
it
with
the
State/
Primacy
Agency
will
encourage
attention
to
peak
events
and
foster
better
understanding
of
peak
TTHM
and
HAA5
occurrence
in
the
distribution
system.

Summary
of

Related
Rule
Activities
This
section
summarizes
the
estimated
number
of
systems
performing
various
rule
activities
and
their
associated
costs,
derived
previously
in
sections
H.
2
through
H.
5.
Exhibit
H.
12a
shows
the
number
of
systems
performing
each
rule
activity,
and
Exhibit
H.
12b
shows
their
associated
costs.
The
estimates
in
Exhibits
H.
12a
and
b
are
broken
out
by
the
Stage
2
DBPR
monitoring
size
categories.
To
combine
system
and
cost
breakouts
comparable
with
treatment
costs
(
derived
in
Chapter
6),
results
in
H.
12a
and
b
need
to
be
transformed
into
EPA's
standard
nine
system
size
categories.
Exhibit
H.
13
(
the
baseline
adjustment
matrix)
shows
the
percentage
of
systems
from
each
of
the
Stage

DBPR
monitoring
size
categories
that
is
in
each
of
EPA's
nine
standard
size
categories
(
see
section
H.
1
for
an
additional
description
of
this
calculation).
Data
in
this
exhibit
are
derived
from
SDWIS
4th

Results
from
Exhibits
H.
12a
and
b
are
multiplied
by
the

adjustment
matrix
in
Exhibit
H.

to
produce
system
and
cost
results
in
EPA's
nine
standard
size
categories
(

Introduction
This
appendix
discusses
several
alternative
monitoring
approaches
and
alterative
approaches
to
IDSE
implementation.
The
Stage
2
DBPR
preamble
requests
comments
on
these
issues.

I.
2
Implications
of
Alternative
Population­
Based
Monitoring
Requirements
for
All
Systems
The
Stage
2
Disinfectants
and
Disinfection
Byproducts
Rule
(
DBPR)
includes
monitoring
requirements
that
the
Stage
2
Microbial­
Disinfectants/
Disinfection
Byproducts
(
M­
DBP)
Federal
Advisory
Committee
(
Stage
2
Federal
Advisory
Committees
Act
(
FACA))
recommended
in
the
Agreement
in
Principle
(
USEPA
2000n).
Many
of
these
monitoring
requirements
were
based
on
those
in
the
1979
TTHM
Rule
and
Stage
1
DBPR.
For
example,
the
frequency
of
monitoring
under
the
Stage
1
DBPR
should
be
influenced
by
source
water
type
(
ground
or
surface
water),
size
of
system,
and
the
number
of
plants
per
system.
For
the
Stage
2
DBPR,
as
under
the
Stage
1
DBPR,
the
Stage
2
FACA
recommended
that
both
routine
and
additional
disinfection
byproduct
(
DBP)
sampling
be
required
on
a
per­
plant
basis.
This
recommendation
is
based
on
the
assumption
that
as
systems
increase
in
size,
they
will
tend
to
have
more
plants
and
increased
complexity
of
water
treatment
and
distribution,
thereby
warranting
increased
monitoring
to
represent
DBP
occurrence
in
the
distribution
system.
The
Stage
2
FACA
also
recommended
higher
frequency
monitoring
for
systems
using
surface
water
than
those
using
ground
water
because
ground
water
tends
to
have
lower
and
more
stable
concentrations
of
organic
DBP
precursors
than
surface
water.
Furthermore,
since
many
ground
water
systems
have
multiple
wells/
entry
points
drawing
water
from
the
same
aquifer,
the
Stage
2
FACA
recommended
that
these
wells
be
considered
as
a
single
plant
with
the
same
monitoring
requirements
prescribed
for
one
plant,
if
approved
by
the
State.

Upon
further
analysis
of
the
Stage
2
FACA
recommendations,
the
Environmental
Protection
Agency
(
EPA)
has
identified
the
following
issues
related
to
the
monitoring
requirements
of
the
Stage
2
DBPR:

°
Basing
increased
monitoring
on
numbers
of
water
treatment
plants
per
system,
as
opposed
to
population,
may
result
in
excessive
or
insufficient
samples
to
represent
DBP
occurrence
in
the
distribution
system.

°
The
proposed
sampling
requirements
for
mixed
systems
(
i.
e.,
those
receiving
disinfected
surface
water
and
ground
water
in
their
distribution
system)
may
be
excessive,
depending
upon
the
system's
characteristics.

°
The
proposed
monitoring
requirements,
based
on
additional
samples
per
water
treatment
plant,
pose
unique
implementation
issues
for
systems
with
temporary
supplies
during
the
year.

Section
V(
F)(
2)
of
the

DBPR
preamble
describes
these
issues
in
detail
and
requests
comment
on
them,
particularly
the
significance
of
a
plant­
based
(
the
proposed
monitoring
scheme)
versus
a
population­
based
monitoring
approach
(
monitoring
requirements
based
on
population
and
source
type
only).
The
purpose
of
this
Appendix
is
to
compare
the
estimated
costs
of
the
monitoring
requirements
for
each
approach.
Appendix
A
of
the
Initial
Distribution

Evaluation
(
IDSE)
guidance
manual
(
USEPA
2003p)
also
discusses
different
implications
of
using
a
plant­
versus
population­
based
approach.

I.
2.1
Summary
of
Alternative
Population­
Based
Monitoring
Requirements
The
Stage
2
DBPR
requires
monitoring
for
(
1)
the
IDSE
and
(
2)
routine
compliance
monitoring.
With
the
population­
based
approach,
the
proposed
monitoring
requirements
for
100
percent
purchasing
systems
would
be
applied
to
all
systems.
Exhibit
I.
1
presents
population­
based
IDSE
Standard
Monitoring
Program
(
SMP)
monitoring
requirements
for
systems
delivering
surface
water,
in
whole
or
in
part
and
systems
delivering
only
ground
water,
respectively.
Exhibit
I.
2
presents
the
number
of
Stage
2B
routine
samples
required
under
the
population­
based
approach
for
systems
using
surface
water
in
whole
or
part,
and
systems
delivering
ground
water
only.
Specified
sampling
locations
would
be
similar
to
those
required
under
the
plant­
based
approach,
reflecting
the
principles
that
the
FACA
recommended
for
capturing
sites
with
high
TTHM
and
HAA5
levels.

Comparison
of
the
Plant­
Based
Approach
to
the
Population­
Based
Approach
This
section
compares
the
current
plant­
based
monitoring
approach
to
the
proposed
populationbased
monitoring
approach.
To
quantify
the
implications
of
promulgating
a
population­
based
instead
of
a
plant­
based
monitoring
scheme,
EPA
estimated
IDSE
and
additional
routine
monitoring
costs
for
both
monitoring
schemes.
This
section
presents
IDSE
cost
estimates
and
additional
routine
monitoring
cost
estimates,
respectively.

Under
a
plant­
based
monitoring
approach,
the
number
of
plants
that
deliver
disinfected
water
to
a
system's
distribution
system
determines
the
number
of
required
sampling
sites.
Some
systems
that
use
the
plant­
based
monitoring
approach,
depending
upon
their
size,
the
number
of
treatment
plants,
and
the
nature
of
their
distribution
system,
may
be
required
to
collect
relatively
large
or
small
numbers
of
TTHM
and
HAA5
samples.
The
number
of
samples
may
be
excessive
or
insufficient
to
adequately
represent
occurrence
since
some
large
systems
have
very
few
large
plants
while
other
much
smaller
systems
have
many
small
plants.
For
example,
in
EPA's
inventory
of
public
water
systems
(
PWSs),
there
are
some
systems
with
only
one
plant
serving
more
than
1
million
people,
whereas
other
systems
serving
fewer
than
100,000
people
have
many
water
treatment
plants,
particularly
those
using
ground
water.

Under
a
population­
based
monitoring
approach,
only
the
system
population
and
source
water
type
determine
the
numbers
of
IDSE
and
routine
samples
taken.
This
approach
is
already
being
proposed
for
systems
that
purchase
100
percent
of
their
finished
water,
but
it
would
have
larger
implications
if
applied
to
all
systems.
States
would
not
be
required
to
make
common
aquifer
determinations,
address
temporary
sources,
or
determine
whether
plants
are
combined
into
a
single
pipe
prior
to
entering
the
distribution
system.
Under
a
population­
based
monitoring
approach,
systems
would
not
be
required
to
conduct
an
IDSE
if
all
their
samples
under
Stage
1
DBPR
were
less
than
or
equal
to
40
µ
g/
L
and
30
µ
g/
L
for
TTHMs
and
HAA5,
respectively.
However,
they
may
still
have
to
select
new
Stage
2B
sites
if
the
required
number
of
Stage
2B
monitoring
sites
is
greater
than
the
number
of
Stage
1
DBPR
sites.
Overall,
the
population­
based
monitoring
approach
may
provide
more
accurate
numbers
of
samples
necessary
to
efficiently
monitor
TTHM
and
HAA5
levels.

Implications
for
IDSE
SMP
National
Costs
Appendix
H
describes
the
IDSE
requirements
and
presents
the
estimated
costs
for
the
proposed
monitoring
scheme
(
referred
to
as
the
plant­
based
approach).
Changing
the
IDSE
and
Stage
2B
monitoring
requirements
from
the
plant­
based
approach
to
the
population­
based
approach
for
all
systems
affects
(
1)
systems
conducting
the
SMP
to
fulfill
the
IDSE
requirements
and
(
2)
systems
waived
from
IDSE
requirements
but
have
more
monitoring
sites
required
for
Stage
2B
than
for
Stage
1.
Note
that
the
estimated
number
of
systems
waived
from
performing
an
IDSE
does
not
change
between
monitoring
approaches.

For
those
systems
estimated
to
conduct
the
SMP
(
approximately
23
percent
of
the
total
systems),
the
number
of
samples
required
and
the
associated
costs
varies
between
the
plant­
and
population­
based
approaches.
Exhibit
I.
3
shows
the
estimated
difference
in
total
samples
under
each
approach.
Under
the
population­
based
approach,
the
total
number
of
required
samples
for
the
SMP
is
estimated
to
be
much
less
(
by
56,543
samples)
than
the
total
number
of
SMP
samples
for
the
plant­
based
approach.

To
compare
costs,
the
total
IDSE
SMP
cost
under
the
population­
based
approach
was
first
estimated
in
Exhibit
I.
4.
In
addition
to
changes
in
IDSE
SMP
costs,
there
may
also
be
changes
in
costs
for
systems
not
performing
the
SMP
or
system­
specific
study
(
SSS).
The
number
of
sampling
sites
for
those
systems
may
increase
or
decrease
from
Stage
1
DBPR
to
Stage
2B
DBPR
requirements.
If
the
number
of
samples
decreases,
the
system
would
eliminate
sites
according
to
the
lowest
DBP
concentrations.
If
the
number
of
samples
increases,
the
system
must
pick
new
monitoring
sites,
which
will
incur
a
small
cost
for
labor.
Exhibit
I.
5
shows
the
number
of
systems
not
conducting
an
IDSE
which
are
estimated
to
have
additional
routine
monitoring
sites
and
the
associated
costs
for
selecting
new
sites
under
the
population­
based
approach.

Exhibit
I.
6
compares
the
total
IDSE
costs
for
the
plant­
based
approach
(
derived
in
Appendix
H)
to
the
total
IDSE
cost
for
the
population­
based
approach
(
Exhibits
I.
4
and
I.
5,
plus
SSS
costs
from
Exhibit
H.

There
is
no
change
in
SSS
costs
from
plant­

to
population­
based
approach.

Implications
for
Additional
Routine
Monitoring
National
Costs
Similar
to
the
IDSE
SMP,
the
number
of
samples
required
for
additional
routine
monitoring
and
the
associated
costs
under
the
plant­
and
population­
based
approaches
varies.
Exhibit
I.
7
shows
that
28,229
fewer
samples
would
be
required
under
the
population­
based
approach,
as
compared
to
the
plantbased
approach.
Exhibit
I.
8
shows
the
breakdown
of
additional
routine
monitoring
costs
under
the
population­
based
approach.
As
seen
in
Exhibit
I.
9,
it
would
cost
approximately
$
6.9
million
less
to
conduct
additional
routine
monitoring
under
the
population­
based
approach,
as
compared
to
those
taken
under
the
plant­

approach.

Implications
of
Alternative
IDSE
Implementation
Schedule
Under
the
proposed
schedule
for
the
Stage
2
DBPR,
States
will
not
have
primacy
by
the
time
many
systems
commence
IDSE
activities.
EPA
is
requesting
comment
on
delaying
implementation
deadlines
for
the
IDSE
to
reduce
the
burden
on
systems
and
EPA
Regions
and
increase
the
technical
involvement
of
the
States.
The
delay
being
considered
is
a
2­
year
delay,
meaning
that
systems
on
the
large
system
implementation
schedule1
will
submit
their
IDSEs
4
years
after
rule
promulgation,
and
systems
on
a
small
implementation
schedule2
will
submit
their
IDSEs
6
years
after
rule
promulgation.

Implications
on
IDSE
System
Costs
EPA
has
concluded
there
would
be
no
measurable
impact
on
the
nominal
estimate
of
IDSE
system
costs
due
to
a
dely
in
IDSE
implementation
schedule;
however,
there
would
be
a
change
in
the
cost
estimate.
The
total
one­
time
costs
of
the
IDSE
(
derived
as
the
sum
of
Exhibits
H.
5a&
b,
H.
6a&
b,
and
H.
7a&
b)
is
estimated
to
be
$
69.4
million.
There
may
be
a
slight
deviation
for
the
alternative
IDSE
implementation
schedule
due
to
a
change
in
the
percent
of
100
percent
purchasing
systems
that
qualify
for
the
40/
30
certification
(
the
percent
of
these
systems
expected
to
qualify
for
the
certification
in
the
current
analysis
is
based
on
observed
data
which
was
reduced
for
the
preferred
regulatory
alternative
since
many
were
not
expected
to
have
2
years
of
data
to
demonstrate
that
all
samples
were

in
percentage,
however,
is
expected
to
have
a
very
minor
impact
on
total
national
costs
(
EPA
assumes
no
change
in
costs).

The
annualized
cost
for
the
IDSE
will
change
if
the
implementation
schedule
is
delayed.
Exhibit
I.
10a
shows
the
estimate
of
when
systems
will
incur
IDSE
costs
for
the
preferred
regulatory
alternative
(
this
is
equivalent
to
Exhibit
D.
4).
Exhibit
I.
10b
shows
when
systems
are
expected
to
incur
costs
for
the
IDSE
under
the
alternative
implementation
schedule.
To
calculate
annualized
costs,
nominal
costs
of
the
IDSE
(
estimated
at
$
69.4
million)
are
used
to
populate
the
IDSE
schedule.
Nominal
cost
results
are
shown
in
Exhibits
I.
11a
and
I.
11b
for
the
preferred
regulatory
alternative
and
the
IDSE
alternative
implementation
schedule,
respectively.
Exhibits
I.
12a
and
I.
12b
show
results
discounted
to
year
2000
dollars
based
on
a
3
percent
discount
rate.
Note
that
the
total
annualized
cost
for
the
IDSE
is
reduced
from
$
3.56
million
per
year
for
the
preferred
regulatory
alternative
(
Exhibit
I.
12a)
to
$
3.36
million
per
year
for
the
IDSE
alternative
implementation
schedule
(
Exhibit
I.
12b),
a
difference
of
$
0.20
million
per
year.

Implication
of
IDSE
Replaced
with
Increased
Monitoring
EPA
is
considering
eliminating
the
IDSE
completely
and
replacing
it
with
increased
compliance
monitoring
during
the
first
year
of
compliance
monitoring,
with
routine
sites
after
the
first
year
based
on
the
increased
compliance
monitoring
(
similar
to
the
process
in
the
IDSE
report).
The
compliance
schedule
remains
the
same.
Increased
monitoring
would
generally
be
equivalent
to
Stage
1
compliance
monitoring
plus
IDSE
monitoring
(
e.
g.,
for
subpart
H
>=
10k,
4
samples/
plant/
quarter
(
Stage
1)
plus
8
samples/
plant/
quarter
(
IDSE,
modified
from
8
samples/
plant/
every
two
months)
for
a
total
of
12
samples/
plant/
quarter),
with
the
additional
sites
chosen
using
a
selection
procedure
based
on
guidance
equivalent
to
that
for
selection
of
IDSE
monitoring
locations.
Compliance
must
be
achieved
at
all
locations.
Systems
could
conduct
something
similar
to
the
IDSE
to
identify
their
routine
monitoring
sites
prior
to
having
to
conduct
increased
compliance
monitoring;
if
State
approved,
systems
would
start
on
routine
monitoring
rather
than
increased
monitoring.

Costs
for
this
alternative
are
assumed
to
be
identical
to
those
presented
in
section
I.
3
(
assuming
that
increased
monitoring
during
the
first
year
of
compliance
monitoring
is
comparable
to
the
IDSE).

Implications
on
IDSE
State
Costs
If
the
IDSE
deadlines
are
delayed
by
2
years,
the
burden
on
States
for
the
IDSE
will
increase.
Exhibit
I.
13a
shows
the
State
costs
for
IDSE
activities
under
the
proposed
rule
schedule
(
this
is
equivalent
to
values
presented
in
Exhibit
H.
11).
EPA
estimates
that
the
number
of
hours
needed
for
State
personnel
to
conduct
IDSE
activities
will
double,
since
State
personnel
(
instead
of
EPA
personnel)
will
be
handling
more
of
the
system­
specific
issues.
This
results
in
a
increase
in
one­
time
State
primacy
costs
for
the
IDSE
from
$
7.7
million
to
$
15.4
million,
and
an
increase
in
total
State
costs
from
$
14.7
to
22.4
million.

In
addition
to
changes
in
nominal
costs,
the
delay
in
IDSE
implementation
will
affect
when
States
will
incur
burden
and
change
the
annualized
costs.
Exhibit
I.
14a
shows
the
rule
activity
schedule
for
States
for
the
preferred
regulatory
alternative,
which
can
be
compared
to
the
rule
activity
schedule
for
States
for
the
alternative
IDSE
implementation
schedule
in
Exhibit
I.
14b.
Exhibit
I.
15a
and
I.
15b
show
the
nominal
costs
projected
through
year
2027
for
the
preferred
regulatory
alternative
and
alternative
IDSE
implementation
schedule.
As
shown
in
Exhibit
I.
16a
and
I.
16b,
the
annualized
costs
for
States
are
expected
to
increase
from
$
1.05
to
$
1.38
million
(
or
by
$
0.33
million)
for
the
alternative
IDSE
implementation
schedule.

Implications
for
Total
Annualized
Costs
of
the
Stage
2
DBPR
Based
on
calculations
shown
previously,
the
total
impact
of
an
alternative
IDSE
implementation
schedule
(
delayed
2
years),
is
to
increase
the
annualized
costs
of
the
rule
by
approximately
$
0.53
million.

13

The
range
of
design
and
average
flows
is
intended
to
cover
all
possible
system
flows.
When
15
flows
fall
between
the
design
or
average
daily
flows
used
to
estimate
unit
costs,
straight
line
interpolation
16
can
be
used
to
estimate
the
capital
or
O&
M
cost.
Design
costs
were
calculated
for
points
ranging
17
between
0.007
million
gallons
per
day
(
MGD)
and
520
MGD.
For
plants
with
flows
less
than
0.007
18
MGD,
the
value
for
0.007
MGD
was
used.
For
plants
with
flows
greater
than
520
MGD,
the
costs
are
19
calculated
by
extrapolating
a
straight
line
between
the
last
two
calculated
cost
points.
Points
are
included
20
in
the
graphs
at
0.0001
MGD
and
1500
MGD
to
show
these
assumptions.
Likewise
for
average
daily
21
flows,
points
were
calculated
between
0.0015
MGD
and
350
MGD.
Points
outside
this
range
show
the
22
assumptions
used
to
extrapolate
costs.
23
24
The
costs
are
copies
from
the
Technologies
and
Costs
Document
for
Control
of
Microbial
25
Contaminants
and
Disinfection
By­
Products
(
USEPA
2003o).
These
unit
costs
have
been
revised
to
26
incorporate
recommendations
from
the
National
Drinking
Water
Advisory
Council
(

Each

lists
the

for
the
technology,
presents
a

showing
the

estimates
for

and
graphically
displays
each

32
to

the
way
in
which
the
costs
increase
with

On
an
overall
level,
baseline
data
on
systems,
plants
and
flows
is
combined
with
unit
cost
data
for
each
technology.
These
data
are
then
combined
with
compliance
forecasts
as
inputs
to
the
cost
models
which
calculate
total
costs.
These
costs
are
then
discounted
over
time
and
then
manipulated
to
give
total
national
costs
as
well
as
household
costs.

presents

modeling
process.
The
model
consists
of
two
parts.
Part
I
estimates
the
number
of
annual
bladder
cancer
cases
avoided
as
a
result
of
the
Stage
2
DBPR.
To
generate
this
estimate,
the
model
calculates
the
number
of
new
bladder
cancer
cases
per
year
attributable
to
DBPs
(
based
on
estimates
of
Population
Attributable
Risk,
PAR)
prior
to
the
Stage
1
DBPR.
Bladder
cancer
cases
avoided
are
calculated
for
both
the
Stage
1
rule
and
the
Stage
2
regulatory
alternatives
using
predicted
changes
in
DBP
occurrence.
Results
are
adjusted
to
account
for
cessation
lag
and
rule
implementation
schedule
to
produce
an
estimate
of
the
average
number
of
bladder
cases
avoided
per
year.

Part
II
of
the
model
involves
valuing
the
cases
avoided.
Distributions
of
value
of
statistical
life
and
willingness
to
pay
estimates
are
used
to
produce
average
results
and
90
percent
confidence
bounds.
