Throughout
this
document,
the
terms
"
State"
or
"
states"
are
used
to
refer
to
all
types
of
primacy
agencies.
There
are
currently
57
primacy
agencies,
including
the
50
States,
the
District
of
Columbia,
U.
S.
territories
(
Puerto
Rico,
U.
S.
Virgin
Islands,
Guam,
American
Samoa,
and
Northern
Marianas),
and
Navajo
Nation.
Though
Wyoming
and
the
District
of
Columbia
do
not
have
primacy,
the
EPA
burden
for
these
activities
is
counted
as
primacy
agency
burden.

Characterization
The
Office
of
Ground
Water
and
Drinking
Water
(
OGWDW)
in
the
Office
of
Water
at
the
United
States
Environmental
Protection
Agency
(
EPA
or
the
Agency)
is
responsible
for
developing
National
Primary
Drinking
Water
Regulations
(
NPDWRs)
as
mandated
by
the
Safe
Drinking
Water
Act
(
SDWA).
Section
1412
of
the
SDWA
requires
EPA
to
establish
NPDWRs
for
contaminants
that
may
adversely
impact
human
health.
The
Act
further
requires
EPA
to
monitor
and
enforce
these
regulations
to
ensure
that
the
nation's
drinking
water
dependably
complies
with
the
maximum
contaminant
levels
(
MCLs)
stipulated
in
the
Code
of
Federal
Regulations
(
CFR),
40
CFR
Part
141,
Subpart
B.

Section
1445
of
the
SDWA
stipulates
that
every
drinking
water
supplier
must
conduct
monitoring,
maintain
records,
and
provide
such
information
as
is
needed
for
EPA
to
implement
its
monitoring
and
enforcement
responsibilities
with
respect
to
the
Act.
State1
governments
 
in
those
states
that
have
assumed
primary
enforcement
responsibility
(
primacy)
for
public
water
systems
(
PWSs)
under
SDWA
Section
1413
 
ensure
that
PWSs
are
complying
with
these
monitoring
requirements.
As
part
of
the
Public
Water
System
Supervision
(
PWSS)
Program,
the
OGWDW
uses
the
Safe
Drinking
Water
Information
System
(
SDWIS)
2
to
record
some
of
the
data
collected
as
a
result
of
NPDWR
requirements.
SDWIS
is
a
database
management
system
that
assists
EPA
in
tracking
and
interpreting
monitoring
data
and
other
program­
related
data.
These
data
assist
EPA
in
fulfilling
its
SDWA
obligations.

This
Information
Collection
Request
(
ICR)
was
prepared
in
accordance
with
the
February
1999
version
of
EPA's
Guide
to
Writing
Information
Collection
Requests
Under
the
Paperwork
Reduction
Act
(
PRA)
of
1995
(
or
"
ICR
Handbook")
prepared
by
EPA's
Office
of
Environmental
Information,
Office
of
Information
Collection,
Collection
Strategies
Division.
The
ICR
Handbook
provides
the
most
current
instructions
for
ICR
preparation
to

and
associated
activities,
which
are
included
in
the

will
be
added
to
this
ICR
when
the
regulations
are
finalized
and
the
original
stand­
alone
ICRs
for
each
expire.

This
ICR
estimates
costs
for
years
2005,
2006,
and
2007.
This
ICR
updates
the
burden
and
cost
estimates
provided
in
the
Microbial
Rules
ICR
dated
November
28,
2001,
which
expires
on
November
30,
2004.
The
burden
and
cost
estimates
for
each
rule
are
discussed
in
greater
detail
in
Section
6
of
this
document.

Continuing
costs
and
burden
for
several
existing
drinking
water
regulations
are
evaluated
in
this
ICR.
The
total
annual
burden
associated
with
this
ICR
is
estimated
to
be
approximately
8.62
million
hours
per
year.
The
total
annual
cost
associated
with
this
ICR
is
estimated
to
be
approximately
$
340.5
million.
The
distribution
of
annual
burden
between
PWSs
and
primacy
agencies
is
approximately
6.87
million
hours
and
1.76
million
hours,
respectively.
The
distribution
of
annual
costs
between
PWSs
and
primacy
agencies
is
approximately
$
284.7
million
and
$
55.8
million,
respectively.
There
is
no
Agency
burden
or
costs
for
this
ICR.
Section
6
and
Appendices
B
through
F
detail
these
burden
and
cost
calculations.

The
approximate
annual
operation
and
maintenance
(
O&
M)
and
capital
costs
are
$
96.9
million
($
74.1
million
for
O&
M
and
$
22.8
million
for
capital).
This
represents
the
"
cost
burden"
as
reported
in
the
OMB
inventory.
Note
that
these
costs
are
for
PWSs
only;
primacy
agencies
do
not
have
capital
or
O&
M
costs
associated
with
the
Microbial

in
the
three
primary
ICRs,
as
well
as
other
drinking

The
EPA
requires
the
information
collected
under
this
ICR
to
carry
out
its
monitoring
and
enforcement
responsibilities
under
the
SDWA.
Without
comprehensive,
up­
to­
date
information
on
drinking
water
contamination,
EPA
would
not
be
able
to
meet
the
SDWA
statutory
requirements
stated
below.

NPDWRs
under
the
SDWA
are
to
include
monitoring
requirements
(
Section
1401
(
1)(
D)).
Specifically,
the
Act
requires
that
C
there
must
be
criteria
and
standards
to
assure
a
supply
of
drinking
water
which
dependably
complies
with
such
maximum
contaminant
levels;
including
quality
control
and
testing
procedures
to
insure
compliance
with
such
levels
and
to
insure
proper
operation
and
maintenance
of
the
system,
...

Section
1445
of
the
SDWA
requires
that
C
every
person
who
is
a
supplier
of
water,
.
.
.
shall
establish
and
maintain
such
records,
make
such
reports,
conduct
such
monitoring,
and
provide
such
information
as
the
Administrator
may
reasonably
require
by
regulation
to
assist
him
in
establishing
regulations,
in
determining
whether
such
person
has
acted
or
is
in
compliance

1)
Surface
Water
Treatment
Rule
The
1986
SDWA
Amendments
required
EPA
to
propose
and
promulgate
a
NPDWR
specifying
criteria
under
which
filtration
would
be
required
as
a
treatment
technique
for
public
water
systems
supplied
by
surface
water
sources
(
Section
1412
(
b)(
7)(
C)(
i)).
In
promulgating
this
regulation
and
setting
the
criteria,
EPA
was
required
to
consider
source
water
quality;
protection
afforded
by
watershed
management
programs;
treatment
techniques,
such
as
disinfection
practices
and
length
of
water
storage;
and
other
factors
relevant
to
protection
of
health.
The
requirements
for
the
SWTR
included
in
this
ICR
help
EPA
promote
public
health
through
proper
operation
of
filtration
techniques.
Additional
SWTR
requirements,
such
as
monitoring
and
watershed
control
programs,
promote
protection
of
public
health
in
the
absence
of
filtration.

2)
Total
Coliform
Rule
The
1986
SDWA
Amendments
required
EPA
to
publish
maximum
contaminant
level
goals
(
MCLGs)
and
promulgate
NPDWRs
for
the
83
contaminants
listed
in
the
Advance
Notice
of
Proposed
Rulemaking
at
47
FR
45502
(
March
4,
1982)
and
48
FR
45502
(
October
5,
1983).
EPA
believes
that
promulgation
of
this
regulation
complied
with
the
statutory
requirements
for
regulating
total
coliforms
in
all
PWSs.

CRITERIA
3(
a)
Non­
duplication
EPA
has
made
an
effort
to
ensure
that
the
data
collection
efforts
associated
with
this
ICR
are
not
duplicated.
EPA
consulted
with
State
environmental
programs,
other
Federal
agencies
(
such
as
the
CDC),
and
regulated
entities
(
such
as
PWSs
and
their
representative
trade
associations).
To
the
best
of
EPA's
knowledge,
data
currently
required
by
the
SDWA
(
and
its
implementing
regulations
codified
at
40
CFR
Parts
141
and
142)
are
not

from
any
other

Public
Notice
Required
Prior
to
ICR
Submission
to
OMB
To
comply
with
the
1995
Amendments
to
the
PRA,
EPA
will
solicit
public
comment
on
this
ICR
for
a
60­
day
period
before
it
is
submitted
to
OMB.
Specifically,
EPA
published
a
notice
in
the
Federal
Register
(
FR)
requesting
comment
on
the
estimated
respondent
burden
and
other
aspects
of
this
ICR
(
to
be
included
as
Appendix
A).
EPA
received
no
comments
during
the
60­
day
comment
period.
An
additional
Federal
Register
notice
will
be
published
prior
to
submission
of
this
ICR
to
OMB.
The
public
comment
period
for
this
additional
notice
is
30
days.

3(
c)
Consultations
Throughout
the
development
and
implementation
of
various
microbial
regulations,
OGWDW
has
held
numerous
meetings
with
interested
stakeholders,
including
State
and
EPA
Regional
personnel
and
PWS
representatives,
to
identify
the
value
and
ease
of
collecting
information
needed
to
fulfill
SDWA
obligations.
As
a
standard
regulatory
development
practice
to
promote
public
involvement,
EPA
formally
solicits
public
comment
on
proposed
drinking
water
rules.
Before
any
rule
is
finalized,
EPA
logs
and
evaluates
all
written
comments
on
proposed
rules.
Additionally,
EPA
usually
holds
public
meetings
during
which
any
interested
party
may
provide
oral
testimony
for
Agency
consideration.
Such
meetings
are
typically
announced
in
the
Federal
Register
notice
accompanying
the
proposed
rule.

In
the
initial
phases
of
program
development,
or
to
confirm
assumptions
on
which
rules
or
guidelines
are
based,
EPA
often
augments
formal
meetings
with
other
workshops
or
meetings
to
gather
information.
The
following
are
specific
examples
of
meetings
and
other
consultations
held
by
EPA
to
address
the
regulations
contained
in
this
ICR
 
°
In
1981,
EPA
held
a
workshop
on
drinking

microbiology.

°
In

In
1985,
the
Federal
Register
presented
a
discussion
on
the
need
for
mandatory
filtration
and
disinfection
of
surface
water.
This
FR
notice
also
requested
public
comment
on
the
subject.

°
A
FR
notice
was
published
on
May
6,
1988,
to
discuss
additional
alternatives
for
the
proposed
SWTR.

°
The
TCR
was
published
on
June
29,
1989.
The
1989
TCR
was
reviewed
as
part
of
the
six­
year
review
of
drinking
water
standards.
EPA
published
its
preliminary
revise/
do
not
revise
decisions
in
the
April
17,
2002
edition
of
the
Federal
Register
to
request
public
comment
(
67
FR
19029­
19090).
EPA
received
and
reviewed
comments
from
44
commenters.
EPA
held
a
stakeholder
meeting
on
May
30,
2002
to
discuss
the
results
of
these
preliminary
findings.
In
July,
2003,
EPA
completed
their
preliminary
review
of
existing
drinking
water
standards,
including
TCR.
Based
on
the
Agency's
preliminary
review,
as
well
as
the
public
comments
received
and
other
new
information,
EPA
believes
that
it
is
appropriate
to
revise
the
TCR.

°
In
1992,
EPA
instituted
a
formal
RegNeg
process
to
discuss
proposed
amendments
to
the
SDWA
with
potentially
affected
parties
(
57
FR
53866;
Nov.
13,
1992).
This
RegNeg
Committee
included
representatives
from
water
utilities
and
other
industries,
State
public
health
and
regulatory
agencies,
environmental
groups,
consumer
groups,
and
EPA.
Following
an
extensive
consensus­
building
effort,
the
RegNeg
Committee
agreed
that
EPA
should
propose
three
rules:
Information
Collection
Rule
(
finalized
in
1996),
a
staged
Enhanced
Surface
Water
Treatment
Rule
(
the
first
stage
was
promulgated
in
December
1998),
and
a
staged
Disinfectants
and
Disinfection
Byproducts
Rule
(
the
first
stage
was
promulgated
concurrently
with
the
IESWTR
in
December
1998).

°
A
microbial
contaminants
and
disinfection
byproducts
advisory
committee,
formed
under
the
authority
of
the
Federal
Advisory
Committees
Act,
convened
in
1997
to
review
the
data
and
assumptions
used
to
support
the
1994
proposed
changes
to
the
SWTR
and
data
that
had
subsequently
been
collected.
In
July
1997,
participants
signed
an
agreement
in
principle,
outlining
the
Committee's
recommendations
to
EPA
on
the
major
components
of
the
IESWTR
and
Stage
1
DBPR.

°
Between
March
and
December
1997,
the
Small
System
Data
Needs
Working
Group
held
six
meetings
to
discuss
availability
of
water
quality
and
financial
data
for
small
systems.

°
Twenty­
four
small
entity
representatives
(
SERs)
were
invited
to
participate
in
a
teleconference
to
discuss
the
FBRR
on
April

1998.
Of
the
24
invited

15
participated
in
the
teleconference.

°
On
August
21,
1998,
a
Small
Business
Advocacy
Review
Panel
(
SBARP)
met
to
discuss
the
proposed
FBRR.
Two
additional
meetings
of
the
SBARP
were
held
between
August
21
and
October
19,
1998.

°
In
September
1998,
the
SBARP
distributed
information
on
regulatory
approaches
and
costs
to
the
SERs
for
review
and
comment.

°
The
SBARP
and
SERs
participated
in
a
joint
teleconference
on
September
25,
1998.

In
an
effort
to
solicit
comments
concerning
the
estimated
burden
for
this
ICR
renewal,
EPA
developed
a
communication
strategy
that
involved
directly
mailing
the
first
Federal
Register
notice
to
over
150
individuals
and
organizations
including
key
respondent
organizations
like
the
Association
of
State
Drinking
Water
Administrators
and
the
American
Water
Works
Association.

Additionally,
consultations
were
conducted
with
major
associations
that
represent
the
entities
that
face
reporting
and
record­
keeping
burdens
associated
with
the
Microbial
Rules.
None
of
these
associations
could
identify
individual
members
who
could
respond
to
questions
about
burden
estimates.
As
they
explained,
their
members
(
states
and
public
water
systems)
rely
on
the
national
offices
of
the
associations
to
track
Federal
Register
notices
and
respond
to
them.

The
most
important
conclusion
is
that
the
associations
felt
that
the
ICR
for
the
Microbial
Rules
was
primarily
about
rules
that
already
had
been
implemented.
Therefore,
any
comments
on
burden
estimates
had
been
presented
to
the
Agency
at
the
time
the
rule
was
promulgated.
Those
associations
that
took
the
time
to
study
the
ICR
did
not
see
any
changes
that
would
affect
burden.
Accordingly,
they
did
not
respond
to
the
Agency's
request
for
comments.
Other
associations
reported
that
they
never
comment
on
ICR's,
or
that
they
lacked
the
internal
resources
to
comment
on
this
specific
ICR.

Comment:
The
staff
and
Executive
Director
of
the
Association
of
State
Drinking
Water
Administrators
reviewed
the
Microbial
ICR
when
it
appeared
in
the
Federal
Register.
Because
the
ICR
referenced
rules
that
were
already
being
implemented
and
for
which
resources
had
already
been
allocated
by
the
states,
it
was
difficult
to
justify
the
time
and
resources
necessary
to
validate
whether
the
burden
estimates
were
reasonable
or
accurate.
Although
the
general
sense
is
that
the
burden
estimates
are
typically
too
low,
states
are
more
interested
in
the
burden
and
resource
needs
for
new
and
future
rules
for
which
they
will
have
to
make
a
case
to
their
upper
management
and
legislatures
for
resources.
To
the
best
of
their
knowledge,
no
states
commented
on
the
ICR.

Comment:
Since
this
was
a
renewal
of
ICR
authorization
for
information
already
being
collected
under
existing
rules,
it
was
not
something
that
the
association
would
have
commented
on
unless
they
knew
of
significant
problems
or
underestimates
of
costs.
This
was
not
the
case.

3(
d)
Effects
of
Less
Frequent
Collection
EPA
has
considered
a
wide
range
of
alternatives
for
frequency
of
data
collection.
Where
possible,
EPA
has
chosen
to
require
the
least
frequent
collection
that
remains
consistent
with
overall
public
health
protection
objectives.
If
data
are
collected
less
frequently,
the
primacy
agency
may
not
identify
in
a
timely
fashion
significant
contaminant
concentrations
which
might
threaten
the
health
and
safety
of
drinking
water
consumers.

For
some
microbial
contaminant
regulations,
the
primacy
agency
has
discretion
in
adjusting
the
monitoring
schedules.
Monitoring
schedules
vary
based
on
the
number
of
people
served
by
a
system,
contaminants
likely
to
be
found,
and
source
of
raw
water
supply.
The
monitoring
frequency
design
also
considers
that
the
number
of
people
served
affects
exposure
to
contaminants,
as
well
as
the
resources
available
to
undertake
monitoring
activity.
Monitoring
frequencies
have
been
carefully
devised
based
on
the
following
factors
 
°
Data
quality
needed
for
a
representative
sample.
°
Precision
and
accuracy
needed
from
the
representative
sample.
°
Number
of
people
served
by
the
system.

Small
Entity
Flexibility
In
developing
this
ICR,
EPA
considered
the
requirement
of
the
Small
Business
Regulatory
Enforcement
Fairness
Act
(
SBREFA)
to
minimize
the
burden
of
information
collections
on
small
entities.
Small
entities
include
"
small
businesses,"
"
small
organizations"
and
"
small
government
jurisdictions."
These
terms
are
defined
below.

A
small
business
is
any
business
that
is
independently
owned
and
operated
and
not
dominant
in
its
field
as
defined
by
the
Small
Business
Administration
regulations
under
Section
3
of
the
Small
Business
Act.


A
small
organization
is
any
non­
profit
enterprise
that
is
independently
owned
and
operated
and
not
dominant
in
its
field.
Microbial

A
small
governmental
jurisdiction
is
the
government
of
a
city,
county,
town,
township,
village,
school
district
or
special
district
that
has
a
population
of
fewer
than
50,000.
This
definition
may
also
include
Indian
Tribes.

The
major
requirement
under
SBREFA
is
a
regulatory
flexibility
analysis
(
RFA)
of
all
rules
that
have
a
"
significant
economic
impact
on
a
substantial
number
of
small
entities."
Since
this
ICR
is
not
currently
associated
with
new
rules,
it
is
not
currently
subject
to
the
SBREFA.

Throughout
the
1992
 
1993
negotiated
rulemaking
process
for
the
Stage
1
DBPR
and
the
IESWTR
and
the
July
1994
proposals
for
these
rules,
a
small
PWS
was
defined
as
a
system
serving
fewer
than
10,000
people.
This
definition
reflects
the
original
1979
standard
for
TTHMs,
which
applied
only
to
systems
serving
at
least
10,000
people.
The
definition
thus
recognizes
that
the
baseline
conditions
from
which
systems
serving
fewer
than
10,000
people
would
approach
disinfection
byproduct
control
and
simultaneous
control
of
microbial
pathogens
would
be
different
than
those
for
systems
serving
10,000
or
more
people.
Consistent
with
the
1994
proposals,
EPA
is
continuing
to
define
a
"
small
system"
(
for
the
purposes
of
the
microbial
contaminant
regulations)
as
a
PWS
that
serves
fewer
than
10,000
people.
Subsequent
to
the
1994
proposals,
EPA
defined
a
"
small
business"
(
for
purposes
of
RFAs
in
drinking
water
regulations)
as
a
PWS
serving
10,000
or
fewer
people.
This
definition
is
consistent
with
the
approach
used
herein
and
in
the
1996
Congressional
amendments
to
SDWA.

EPA
has
made
significant
efforts
to
minimize
the
burden
for
all
respondents,
particularly
for
small
entities.
In
setting
both
MCLs
and
monitoring
requirements,
EPA
has
been
able
to
minimize
burden
for
small
entities
as
detailed
below.

1)
Surface
Water
Treatment
Rule
Only
a
small
percentage
of
small
systems
use
surface
water
supplies;
therefore,
this
rule
does
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.
Since
system
size
is
the
key
determinant
of
the
monitoring
frequency
requirements
of
the
SWTR,
systems
serving
fewer
than
3,300
people
will
have
the
least
stringent
monitoring
requirements.

EPA
will
allow
a
reduction
in
the
frequency
of
turbidity
monitoring
from
six
samples
per
day
to
one
sample
per
day
for
systems
using
slow
sand
filtration
treatment
or
other
eligible
technologies.
Systems
serving
fewer
than
500
people
may
also
reduce
sampling
to
once
per
day
regardless
of
filtration
type.

2)
Total
Coliform
Rule
The
number
of
required
coliform
samples
varies
directly
with
system
size.
Specifically,
for
community
water
systems
(
CWSs),
the
number
of
samples
range
from
a
minimum
of
one
sample
per
month
for
systems
serving
fewer
than
1,000
people
to
480
samples
per
month
for
those
serving
3,960,001
or
more
people.
This
requirement
is
codified
at
40
CFR
§
141.21(
a).
Generally,
quarterly
monitoring
must
be
conducted
at
noncommunity
water
systems
(
NCWSs)
Microbial
Rules
ICR
November
2004
41
using
only
ground
water
that
is
not
under
the
direct
influence
of
surface
water
and
serving
1,000
or
fewer
people.
As
provided
for
in
§
141.21(
a)(
3)(
i),
however,
the
primacy
agency
may
reduce
the
quarterly
monitoring
frequency
as
a
result
of
a
sanitary
survey.

3)
Interim
Enhanced
Surface
Water
Treatment
Rule
Except
for
sanitary
survey
requirements,
which
are
carried
out
by
the
primacy
agency,
the
IESWTR
only
applies
to
systems
serving
at
least
10,000
people.
Accordingly,
the
rule
does
not
have
a
significant
impact
on
small
entities.

4)
Filter
Backwash
Recycling
Rule
The
FBRR
applies
to
both
large
and
small
systems.
Therefore,
the
rule
will
have
an
effect
on
small
entities.
Accordingly,
as
part
of
the
economic
analysis
for
the
rule,
EPA
is
certifying
that
this
rule
will
not
have
a
significant
impact
on
a
substantial
number
of
small
systems.
As
a
result,
an
RFA
was
not
required
to
be
conducted.

5)
Long
Term
1
Enhanced
Surface
Water
Treatment
Rule
The
LT1ESWTR
applies
only
to
subpart
H
systems
serving
less
than
10,000
people.
The
rule
will,
therefore,
have
an
effect
on
small
entities.
After
considering
the
economic
impacts
of
the
rule
on
small
entities,
EPA
certifies
that
this
action
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.
This
certification
can
be
made
because
the
Agency
has
determined
that
less
than
one
percent
of
small
entities
will
experience
an
impact
of
less
than
one
percent
of
their
annual
revenues
or
expenditures.
No
affected
small
governmental
jurisdictions
are
expected
to
incur
annual
costs
exceeding
three
percent
of
their
annual
revenue.
Accordingly,
an
Initial
Regulatory
Flexibility
Analysis
was
not
required
to
be
conducted.

This

to

and
describes
the
change
in
annual

as
compared
with
the
current

inventory.

EPA
is
committed
to
accurately
characterizing
the
burden
and
costs
of
rules
it
promulgates.
Consequently,
EPA
has
refined
some
of
the
assumptions
for
calculating
the
burden
and
costs
associated
with
implementing
the
drinking
water
regulations
contained
in
this
ICR.
For
this
update,
many
assumptions
were
revised
based
on
program
changes
and
well­
documented
changes
in
some
data.
To
provide
a
comparable
basis
on
which
to
calculate
the
requirements
addressed
by
the
Microbial
Rules
ICR,
EPA
applied
uniform
assumptions
to
all
rules.

Wherever
possible,
activity­

assumptions
were
carried
forward
from
previous
ICRs.
However,
if
updated
data
were
available
(
e.
g.,

the
most
recent
data
were
used
in
burden
calculations.
Appendices

show
the
assumptions
and
detailed
burden
calculations
for
each

describes
the
bases
for
the

estimates
for
each
rule.

1)
Surface
Water
Treatment
Rule
Activities
associated
with
the
SWTR
account
for
0.33
million
annual

hours.
The
assumptions
used
to
calculate
the
SWTR
burden
are
based
largely
on
assumptions
carried
forward
from
the
2001
Microbial
Rules
ICR.
This
ICR
includes
burden
estimates
for
all
components
of
the
SWTR
except
disinfectant
residual

and
associated
activities,
which
are
included
in
the
DDBP/
Chem/

Rules
ICR.
For
unfiltered
systems,
burden
estimates
include
raw
water
sampling
for
coliform,
on­
site
inspections,
watershed
management,
and
raw
water
turbidity
monitoring.
The
burden
for
filtered
systems
includes
only
finished
water
turbidity
monitoring.
Section

describes
the
reasons
for
changes
between
the

shows
the

Annual

are
estimated
at
approximately
$
284.7
million,
which
consists
of
$
187.7
million
in
labor
costs,
$
74.1
million
in
O&

costs,
and
$
22.8
million
in
capital
costs.

PWS
labor
costs
are
based
on
the
number
of
burden
hours
times
the
average
hourly
wage
rate,
including
overhead.
The
average
hourly
wage
rate
is
the
rate
quoted
by

Statistics
for
SOC
Code
51­
8031,
"
Local
Government
 
Water
and

Operators."
The
quoted
rate
was
$
16.64
in
2002
dollars
(
see
http://
stats.
bls.
gov).
For
consistency,
this
rate
has
been
inflated
to
September
2003
dollars
using
the
Employment
Cost
Index.
The
inflated
rate
is
$
17.09.
In
addition,
60
percent
overhead
was
assumed,
bringing
the
loaded
rate
to
$
27.34
in
September
2003
dollars.

In

to
the
labor
costs,
there
are

The
SWTR,
IESWTR,
and
LT1ESWTR
also
include
capital
costs
for
turbidity

equipment.
For
these
rules,
capital
costs
are
estimated
based
on
vendor
estimates
and
costing
equations
for
in­
line
and
bench­
top
turbidimeters,
or
SCADA
systems
needed
to
comply
with

requirements.
Capital
costs
are
annualized
based
on
the
replacement
period
for
turbidity

equipment
(
estimated
to
be
7
years).

Cost
to
Primacy

Exhibit
7
shows
that
the
annual
costs
to
primacy
agencies
are
estimated
at
approximately
$
55.8
million
in
labor
costs.
The
labor
costs
are
based
on
an
average
full
time
equivalent
(
FTE)
cost
of
$
66,008
including
overhead,
which
equates
to
approximately
$
31.73
per
hour.
13
This
rate,
which
has
been
inflated
to
year
2003
dollars,
is
based
on
the
rate
($
55,000)
suggested
by

estimates
that
the
number
of
PWS

All
PWSs
are
not
necessarily
subject
to
each
of
the
information
collection
requirements
contained
in
this
ICR.
Each
rule
associated
with
this

are
subject
to
that
particular
requirement.
The

15
This

are
a
result
of
adjustments
to
individual

a
result
of
updating

The

will
begin
disinfection
benchmarking;
2)
PWSs
serving

3)
All

This

Burden
Statement
The
public
reporting
burden
for
collections
included
in
this
ICR
is
detailed
in
Exhibit
13
above.
The
annual
respondent
burden
is
estimated
to
average
approximately
8.62
million
hours,
of
which
6.87
million
hours
are
attributable
to
PWSs
and
1.76
million
hours
to
primacy
agencies.
These
estimates
include
time
for
gathering
information
as
well
as
developing
and
maintaining
records.

Burden
means
the
total
time,
effort,
or
financial
resources
expended
by
people
to
generate,
maintain,
retain,
disclose,
or
provide
information
to
or
for
a
Federal
agency.
This
includes
the
time
needed
to
review
instructions;
develop,
acquire,
install,
and
utilize
technology,
and
systems
for
the
purposes
of
collecting,
validating,
and
verifying
information,
processing
and
maintaining
information,
and
disclosing
and
providing
information;
adjust
the
existing
ways
to
comply
with
any
previously
applicable
instructions
and
requirements;
train
personnel
to
be
able
to
respond
to
a
collection
of
information;
search
data
sources;
complete
and
review
the
collection
of
information;
and
transmit
or
otherwise
disclose
the
information.
An
agency
may
not
conduct
or
sponsor,
and
a
person
is
not
required
to
respond
to,
a
request
for
information
collection
unless
it
displays
a
currently
valid
OMB
control
number.
The
OMB
control
numbers
for
EPA's
regulations
are
listed
in
40
CFR
Part
9
and
48
CFR
Chapter
15.

To
comment
on
the
Agency's
need
for
this
information,
the
accuracy
of
the
provided
burden
estimates,
and
any
suggested
methods
for
minimizing
respondent
burden,
including
the
use
of
automated
collection
techniques,
