Program,
a
national
program
mandated
by
the
Safe
Drinking
Water
Act
(
SDWA).
Section
1412
of
the
SDWA
requires
EPA
to
establish
National
Primary
Drinking
Water
Regulations
(
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)/
Maximum
Residual
Disinfectant
Levels
(
MRDLs),
as
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
C
in
those
States
that
have
assumed
primary
enforcement
responsibility
(
primacy)
for
public
water
systems
(
PWSs)
under
SDWA
Section
1413
C
ensure
that
PWSs
are
complying
with
these
monitoring
requirements.
As
part
of
the
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

Requests
Under
the
Paperwork

EPA
has
organized
UCMR
contaminants
into
three
lists
based
on
analytical
method
readiness
and
current
contaminant
occurrence
data;
specifically:
List
1
(
Assessment
Monitoring),
List
2
(
Screening
Survey),
and
List
3
(
Pre­
Screen
Testing).
Only
List
1
and
2
contaminants
are
addressed
in
this
ICR,
as
monitoring
for
List
3
contaminants
will
be
required
only
after
future
rulemakings
specify
analytical
methods
for
List
3
contaminants.
For
simplicity,
UCMR
assessment
monitoring
for
List
1
contaminants
and
screening
survey
monitoring
for
List
2
contaminants
are
hereafter
referred
to
as
List
1
and
List
2.

Includes
only
the
rule
components
relating
to
disinfectant
residual
monitoring
and
associated
activities.
Under
the
SWTR,
systems
disinfecting,
but
not
filtering
their
water,
must
comply
with
monitoring
requirements
for
disinfection
residuals
in
the
distribution
system
and
disinfection
parameters
at
or
near
the
first
customer.
Monitoring
of
disinfection
parameters
for
finished
water
must
include
the
disinfectant
residual
levels,
disinfectant
contact
time,
pH,
and
water
temperature.
In
addition,
systems
must
identify
the
disinfectant
used
and
must
calculate
the
contact
time
(
CT)
value
on
the
basis
of
the
disinfection
parameters.
The
CT
value
is
used
to
determine
the
operating
efficiency
in
removing
or
inactivating
Giardia
and
viruses.
All
remaining
SWTR
requirements
are
included
in
the
Microbial
ICR.

are
associated
with
rulemakings
that

This
ICR
examines
PWS
and
primacy
agency
burden
and
cost.
EPA

This
ICR
estimates
costs
for
years
2002,
2003,
and
2004.
In
the
future,
OGWDW
will
amend
the
Disinfectants
and
Disinfection
Byproducts,
Chemical,
and
Radionuclides
(
DDBP/
Chem/
Rads)
ICR
to
include
Lead
and
Copper
Rule
(
LCR)
burden,
which
is
currently
addressed
in
a
separate
ICR
(
OMB
No.
2040­
0210);
the
LCR
ICR
expires
in
September
2002.
The
burden
for
LCR
through
2004
will
be
amended
to
this
ICR.
Future
renewals
of
this
ICR
will
include
the
burden
for
LCR
for
the
entire
3­
year
ICR
renewal
period.
Similarly,
burden
for
the
Arsenic
Rule,
which
Disinfectants/
Disinfection
Byproducts,
Chemical,
and
Radionuclides
ICR
November
29,
2001
3
is
also
currently
addressed
in
a
separate
ICR
(
OMB
No.
2040­
0231),
will
be
amended
to
the
DDBP/
Chem/
Rads
ICR
when
it
expires
in
January
2004.

In
addition,
future
chemical­
related
rulemakings,
such
as
Radon
and
the
Stage
2
DBPR,
will
be
added
to
this
ICR
as
amendments
when
regulations
are
finalized.
New
rule
ICRs
explain
the
burden
up
to
the
point
that
a
rule
is
fully
implemented,
which
is
usually
more
than
3
years.
However,
only
the
applicable
burden
which
corresponds
to
the
3­
year
period
covered
in
this
ICR
will
be
amended.
Future
renewals
of
this
ICR
will
include
the
applicable
burden
for
the
new
rules
for
the
entire
3­
year
ICR
renewal
period.
For
example,
if
a
chemical­
related
rule
is
promulgated
in
January
of
2003,
the
DDBP/
Chem/
Rads
ICR
will
be
amended
to
add
the
burden
for
the
new
rule
for
2003
and
2004.
For
the
next
renewal
of
the
DDBP/
Chem/
Rads
ICR,
the
burden
will
cover
the
new
rule
for
the
entire
3­
year
renewal
period.

For
several
rules
(
Chemical
Phases
II,
IIB,
and
V;
1976
Radionuclides
Rule;
TTHM
Rule;
and
SWTR),
this
ICR
updates
and
augments
the
burden
and
cost
estimates
provided
in
the
ICR
for
the
PWSS
Program
dated
December
20,
1993,
which
expires
on
September
30,
2001
(
see
Appendix
B).
The
Stage
1
DBPR
ICR
is
being
renamed
as
the
DDBP/
Chem/
Rads
ICR.
In
addition,
it
updates
and
augments
the
Stage
1
DBPR
ICR
burden
(
the
predecessor
ICR
to
this
ICR;
OMB
No.
2040­
0204),
the
UCMR
ICR
(
OMB
No.
2040­
0208),
and
the
2000
Radionuclides
ICR
(
OMB
No.
2040­
0228).
Burden
and
costs
for
all
of
these
rules
are
consolidated
into
this
ICR.

The
total
annual
burden
associated
with
this
ICR
is
estimated
to
be
4.34
million
hours
per
year.
The
total
annual
cost
associated
with
this
ICR
is
estimated
to
be
approximately
$
261.7
million.
The
distribution
of
annual
burden
between
PWSs
and
primacy
agencies
is
approximately
2.51
million
hours
and
1.83
million
hours,
respectively.
The
distribution
of
annual
costs
between
PWSs
and
primacy
agencies
is
approximately
$
208.8
million
and
$
52.9
million,
respectively.
The
Agency
burden
for
this
ICR
is
estimated
at
13,549
hours
annually,
at
an
annual
cost
of
$
3.0
million.
Section
6
and
Appendices
F
through
K
provide
details
of
all
burden
and
cost
estimates.

The
approximate
annual
O&
M
and
capital
costs
are
$
148.5
million
($
142.2
million
for
O&
M
and
$
6.3
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
rules
in
this
ICR.

The
total
annual
number
of
respondents
for
this
ICR
is
167,894;
57
of
these
respondents
are
primacy
agencies
and
the
remaining
respondents
are
existing
PWSs.
The
total
annual
number
of
responses
for
these
respondents
is
2.67
million
(
1.67
million
for
PWSs
and
1.00
million
for
primacy
agencies).

This
section
identifies
the
regulatory
or
statutory
authority
for
the
information
collection
activities
covered
in
this
ICR
and
explains
EPA's
need
for
the
information.
Section
4
of
this
ICR
contains
a
summary
of
the
major
types
of
recordkeeping
and
reporting
requirements
for
chemical
contaminants
covered
by
this
ICR.

To
allow
the
public
to
better
understand
the
impact
of
the
recordkeeping
and
reporting
requirements
stemming
from
the
SDWA
and
40
CFR
Parts
141
and
142,
OGWDW
has
reorganized
its
ICRs
so
that
related
activities
are
addressed
in
the
same
ICR.

ICR
includes
rules
addressing
chemical
contaminants.
The
specific
chemical
regulations
addressed
in
this

2002,
OGWDW
will
amend
the
ICR
to
include
the
LCR
burden,
which
is
currently
addressed
in
a
separate
ICR.
Similarly,
burden
for
the
Arsenic
Rule,
which
is
also
currently
addressed
in
a
separate
ICR
will
be
amended
to
the
DDBP/
Chem/

ICR
when
it
expires
in
January
2004.
In
addition,
future
chemical­
related
rulemakings,
such
as
Radon
and
the
Stage
2
DBPR,
will
be
added
to
this
ICR
as
amendments
when
the

The
1986
Amendments
to
SDWA
require
the
Agency
to
publish
maximum
contaminant
level
goals
(
MCLGs)
and
promulgate
NPDWRs
for
83
specific
contaminants.
Promulgation
of
the
chemical­
related
rules
contained
in
this
ICR
complies
with
the
statutory
requirements
for
some
of
these
contaminants.
Promulgation
of
the
Stage
1
DBPR
complies
with
the
amended
statutory
requirements
for
these
contaminants.

In
addition,
the
1986
SDWA
Amendments
require
the
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)).
Promulgation
of
the
SWTR
satisfies
this
SDWA
requirement.

The
information
collected
under
this
ICR
is
required
by
EPA
to
carry
out
its
monitoring
and
enforcement
responsibilities
under
SDWA.
Without
comprehensive,
up­
to­
date
information
on
chemical
contaminants
present
in
drinking
water,
the
Agency
would
not
be
able
to
meet
the
SDWA
statutory
requirements.

Section
1401
of
the
SDWA
requires
that
 
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...

Further,
§
1445
of
the
SDWA
requires
that
 
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
with
this
title...

In
addition,
§
1401(
1)(
d)
of
the
SDWA
1996
Amendments
defines
NPDWRs
to
include
"
criteria
and
procedures
to
assure
a
supply
of
drinking
water
which
dependably
complies
with
such
maximum
contaminant
levels;
including
accepted
methods
for
quality
control
and
testing
procedures
..."
This
section
authorizes
EPA
to
require
systems
and
laboratories
to
use
Agencyapproved
methods
and
quality
assurance
criteria
for
collecting
and
analyzing
water
samples.

To
implement
its
compliance
oversight
and
enforcement
responsibilities
under
the
SDWA,
EPA
requires
PWSs
to
monitor
for
various
drinking
water
contaminants.
The
results
of
this
monitoring
must
be
reported
to
primacy
agencies,
which
in
turn
report
a
specified
subset
of
this
information
in
SDWIS.
Additionally,
both
PWSs
and
primacy
agencies
must
maintain
records
of
analysis
results
and
other
related
activities
(
e.
g.,
sanitary
survey
results).
Without
comprehensive,
up­
to­
date
information
on
drinking
water
contamination
(
as
provided
by
SDWIS),
EPA
would
not
be
able
to
ensure
a
supply
of
drinking
water
which
dependably
complies
with
such
maximum

10
contaminant
levels.
If
these
monitoring
requirements
were
voluntary,
EPA
would
not
receive
timely,
comprehensive
data
on
contaminant
levels
and
associated
acute
and
long­
term
public
health
risks.
Specifically,
voluntary
monitoring
would
not
 

Reliably
occur
with
sufficient
frequency.


Follow
uniform
national
standards
on
quality
of
sampling,
collection,
and
analysis.


Ensure
that
monitoring
addresses
all
contaminants
listed
in
the
regulations.

Thus,
without
this
information
collection,
EPA
would
not
be
able
to
guarantee
safe
drinking
water
for
the
nation.

Additionally,
EPA
uses
SDWIS
data
to
estimate
the
costs
of
new
regulations
and
to
conduct
economic
and
policy
analyses
that
promote
cost­
effective
regulatory
approaches.
These
uses
are
discussed
in
more
detail
in
Section
2(
b)
below.

Section
4
of
the
ICR
contains
a
summary
of
the
major
types
of
chemical
contaminant
recordkeeping
and
reporting
requirements,
as
mandated
by
40
CFR
Parts
141
and
142.
Specifically,
most
reporting
required
by
PWSs
can
be
found
in
§
§
141.31,
141.134,
and
141.35.
Most
recordkeeping
requirements
for
PWSs
are
codified
in
§
141.33,
which
requires
that
the
results
of
chemical
analyses
be
kept
for
a
period
of
at
least
10
years.
Reporting
and
recordkeeping
required
by
States
can
be
found
in
§
§
142.15
and
142.14,
respectively.

Uses
of
the
Data
Primary
users
of
the
data
collected
under
this
ICR
are
EPA
Headquarters,
PWS
managers,
and
primacy
agencies,
which
include
State

and,
in
some
instances,
EPA
Regional

Alert
the
public,
through
notices
in
the
mass
media
or
water
bills,
when
the
system
is
not
in
compliance
with
Federal
and
State
regulations
so
that
they
may
take
actions
to
minimize
exposure
to
potentially
harmful
drinking
water
contaminants.

Quarterly
and
annual
reports
that
primacy
agencies
must
submit
to
EPA
include
analytical
results,
by
contaminant
type,
for
each
PWS.
This
reporting
is
required
to
establish
primacy
and
maintain
eligibility
for
grants.
All
of
this
information
is
stored
in
SDWIS,
which
supports
overall
maintenance
and
retrieval
of
information.
SDWIS
contains
information
on
the
following:
inorganic
chemicals,
organic
chemicals,
radionuclides,
microbiological
contaminants,
and
turbidity.
Thus,
SDWIS
allows
EPA
to
compare
water
system­
level
compliance
data
from
year
to
year
and
to
analyze
compliance
trends
at
the
system,
State,
and
national
program
levels.

Regulatory
Enforcement
Using
SDWIS,
system­
level
compliance
data
may
be
compared
from
year
to
year
and
trends
in
compliance
data
can
be
evaluated
at
the
system,
State,
and
national
program
levels.
Primacy
agencies
are
responsible
for
enforcement
activities
and
can
use
SDWIS
data
to
track
compliance
progress
in
their
jurisdictions,
to
identify
enforcement
targets
and
systems
requiring
remedial
action,
and
to
monitor
progress
of
capacity
development
strategies.
The
primacy
agency
must
also
track
enforcement
actions
issued
against
each
PWS
not
in
compliance
with
drinking
water
standards
and
evaluate
the
system's
status
in
meeting
schedules
designed
to
return
the
PWS
to
compliance.

On
a
quarterly
basis,
EPA
uses
SDWIS
to
generate
a
list
of
PWSs
that
are
in
significant
non­
compliance
(
SNC).
EPA
can
use
these
data
to
oversee
State
programs
and
support
Federal
enforcement
actions
in
cases
where
States
fail
to
enforce
against
violations
of
drinking
water
standards.
If
a
State
has
failed
to
take
timely
and
appropriate
action,
EPA
may
become
directly
involved
in
enforcement
by
issuing
an
administrative
order.
If
the
system
does
not
comply
with
the
order,
EPA
may
seek
an
administrative
penalty
or
court
action.
EPA
may
also
take
action
against
a
PWS
before
it
is
in
SNC.

Another
output
of
SDWIS
evaluations
is
an
annual
compliance
report
prepared
jointly
by
OGWDW
and
the
Office
of
Enforcement
and
Compliance
Assurance
(
OECA),
which
provides
a
national
perspective
on
contaminant­
by­
contaminant
trends
in
compliance.
This
report
allows
OGWDW
managers
to
examine
important
policy
questions
relating
to
enforcement.
For
example,
managers
may
use
this
information
to
determine
if
current
regulations
and
implementing
policies
are
producing
intended
results.
If
not,
they
may
then
identify
the
types
of
changes
needed
to
meet
program
objectives.

Oversight
of
State
Programs
State
reporting
is
a
condition
for
maintaining
primacy.
Primacy
agencies
play
a
crucial
role
in
implementing
the
SDWA,
and
EPA
is
charged
with
overseeing
the
performance
of
these
States.
Generally,
EPA
Regional
Offices
perform
this
duty
and
use
SDWIS
data
to
develop
summary
statistics
on
individual
State
performance.

In
addition,
EPA
uses
the
data
to
evaluate
the
impact
of
SDWA
requirements
on
primacy
agencies.
The
data
allow
EPA
to
gauge
if
it
has
accurately
estimated
the
impact
of
the
SDWA
on
States
implementing
and
enforcing
the
various
drinking
water
regulations.
Such
data
provide
EPA
with
the
opportunity
to
improve
program
effectiveness
and
efficiency
and
identify
areas
requiring
additional
focus.
Specifically,
EPA
uses
the
Resource
Analysis
Computer
Program
for
State
Drinking
Water
Agencies
to
support
this
State
impact
evaluation.
The
model
contains
a
comprehensive
list
of
activities
required
to
operate
a
drinking
water
program.

Implementation
Assistance
EPA
also
uses
the
data
collected
to
assist
small
systems
in
implementing
SDWA
requirements,
including
developing
variances
and
exemptions
and
evaluating
PWS
capacity.
If
a
PWS
is
unable
to
meet
standard
requirements
due
to
source
water
quality
or
affordability
concerns,
a
variance
or
exemption
would
allow
the
system
to
comply
with
slightly
different
drinking
water
standards
or
implementation
schedules
that
are
still
protective
of
public
health.
Capacity
development
is
a
State
effort
to
help
all
drinking
water
systems,
particularly
small
systems,
improve
their
finances,
management,
infrastructure,
and
operations.
This
helps
ensure
that
safe
drinking
water
is
provided,
consistently,
reliably,
and
cost­
effectively.

Economic
and
Policy
Analyses
SDWIS
data
are
used
extensively
in
developing
Economic
Analyses
(
EAs)
of
proposed
new
regulations
or
revisions
of
existing
regulations.
The
data
help
to
determine
a
system's
susceptibility
and
vulnerability
to
contaminants,
as
well
as
the
potential
for
co­
occurrence
of
contaminants.
Data
are
also
used
by
OGWDW
to
conduct
analyses
used
in
developing
new
policies,
regulations,
and
guidance
documents.
When
analyzing
economic
or
financial
impacts
on
the
water
supply
industry
or
consumers,
EPA
uses
compliance
data
from
SDWIS,
together
with
other
national
survey
data,
to
estimate
the
number
of
systems
that
would
have
to
install
treatment
technologies
or
apply
contamination
reduction
measures
to
reduce
public
health
risks.
Without
such
data,
EPA
would
be
unable
to
predict
costs
and
benefits
that
systems
would
incur
under
new
or
revised
regulations.

Additionally,
EPA
uses
such
data
to
revise
characterizations
of
public
health
and
environmental
risks.
This
information
is
then
used
to
determine
if
less
stringent
regulation
is
warranted.
For
example,
EPA
will
use
the
unregulated
contaminant
monitoring
data
to
formulate
future
drinking
water
program
regulations.
Specifically,
the
data
generated
by
the
UCMR
will
be
used
to
evaluate
and
prioritize
contaminants
on
the
Drinking
Water
Contaminant
Candidate
List
(
CCL),
a
list
of
contaminants
EPA
is
considering
for
possible
new
drinking
water
standards.

These

about
drinking
water
standards
are
based
on
sound
science.

Consultations
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.
Throughout
the
development
and
implementation
of
various
chemical
regulations,
OGWDW
held
numerous
meetings
with
interested
stakeholders,
including
State,

To
develop
the
Stage
1
DBPR,
EPA
instituted
a
formal
regulatory
negotiation
(
RegNeg)
process
in
1992
with
potentially
affected
parties
(
57
FR
53866;
Nov
13,
1992).
This
RegNeg
Committee
included
representatives
from
the
water
and
other
industries,
State
public
health
and
regulatory
agencies,
environmental
groups,
consumer
groups,
and
EPA.


Development
of
the
UCMR
included
stakeholder
meetings
to
discuss
the
contaminant
list
on
a
general
basis.
Additional
meetings
focused
on
particular
issues
and
were
conducted
through
the
National
Drinking
Water
Advisory
Council's
(
NDWAC's)
Working

SMF
was

Rule
and
revised
under
Phase
IIB
and
Phase
V
regulations
(
CFR
§
§
141.23­
141.25).
It
standardizes
monitoring
requirements
within
chemical

and
synchronizes
monitoring

across
chemical

into
specific
3­

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

For
the
Chemical
Phase,
TTHM,
and
Stage
1
DBPR,
the
primacy
agency
has
discretion
in
adjusting
monitoring
schedules,
where
possible.
Monitoring
frequencies
have
been
carefully
devised
based
on
the
following
 

Type
of
contaminant.


Type
and
size
of
system.


System
vulnerability.


Contaminant
history.


Factors
contributing
to
DBP
formation
(
Stage
1
DBPR
only).

Similarly,
UCMR
monitoring
frequencies
were
determined
based
on
statutory
requirements,
which
specify
that
monitoring
be
varied
based
on
the
number
of
persons
served
by
a
system,
contaminants
likely
to
be
found,
and
source
of
supply.
The
monitoring
frequency
design
also
considers
that
the
number
of
persons
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.


Source
of
the
supply
(
e.
g.,
surface
water
or
ground
water).


Contaminants
likely
to
be
found.


Temporal
variability
in
occurrence.


Synchronization
with
the
Standardized
Monitoring
Framework
(
SMF)
for
Phase
II/
V.
9
For
the
UCMR,
reduced
data
collection
would
seriously
affect
the
integrity
of
the
data
and
result
in
insufficient
data
to
fulfill
the
needs
envisioned
by
the
1996
SDWA
Amendments.
These
data
will
be
used
for
continued
development
of
the
CCL,
support
of
the
Administrator's
regulatory
determinations,
and
overall
regulation
development.

MAXIMUM
RESIDUAL
DISINFECTANT
LEVELS
(
MRDLS)

Disinfectants
are
added
during
water
treatment
to
control
waterborne
microbial
contaminants.
Some
residual
disinfectants
will
remain
in
water
after
treatment.
MRDLs
protect
public
health
by
setting
limits
on
the
level
of
residual
disinfectants
in
drinking
water.

Chlorine
and
Chloramines
MRDLs
Chlorine
is
a
widely
used
and
highly
effective
water
disinfectant.
The
MRDL
for
chlorine
is
4.0
mg/
L.
Chloramines
are
formed
when
ammonia
is
added
during
chlorination
to
suppress
formation
of
many
byproducts.
The
MRDL
for
chloramines
is
4.0
mg/
L
(
measured
as
Cl
2).


Routine
Monitoring
(
§
141.132).
Systems
must
take
samples
for
the
residual
disinfectant
levels
at
the
same
points
in
the
distribution
system
and
at
the
same
time
as
total

samples
(
Subpart
H
systems
are
already
taking
these
samples
under
the
SWTR).


Reduced
Monitoring
(
§
141.132).
There
is
no
reduced
monitoring
for
chlorine
and
chloramines.


Compliance
Requirements
(
§
141.133).
Compliance
with
the
MRDL
is
based
on
the
running
annual
arithmetic
average
of
samples.
If
the
average
of
quarterly
averages
for
any
consecutive
4­
quarter
period
exceeds
the
MRDL,
the
system
must
notify
the
public
and
report
the
exceedance
to
the
State.
If
a
system
switches
between
the
use
of
chlorine
and
chloramines,
compliance
must
be
determined
by
including
all
monitoring
results
for
both
chlorine
and
chloramines
in
calculating
compliance.

Chlorine
Dioxide
MRDL
Chlorine
dioxide
is
used
primarily
for
the
oxidation
of

odor­
causing
organic
compounds
in
water.
It
can
also
be
used
for
the
oxidation
of
iron
and
manganese,
and
color
and
is
a
powerful
disinfectant
and
algicide.
Chlorine
dioxide
reacts
with
impurities
in
water
very
rapidly
and
is
dissipated
very
quickly.
About
60
to
70
percent
of
the
chlorine
dioxide
is
converted
to
chlorite
in
the
treatment
process.


Routine
Monitoring
(
§
141.132).
Systems
must
take
a
daily
sample
at
the
entrance
to
the

If
the
system
exceeds
the
MRDL
in
any

or
fails
to
take
samples
in
the
distribution
system
the
following
day,
this
constitutes
an
acute

people
must
submit
their
monitoring
plans
to
the
State
for
review.
This
is
another
reporting
requirement
for
some
PWSs.
The
State
may
require
changes
in
any
element
of
the
system's
monitoring
plan.

2)
Chemical
Phase
Rules
The
chemical
monitoring
requirements
apply
to
CWSs
and
NTNCWSs,
although
transient
noncommunity
water
systems
(
TNCWSs)
must
also
sample
for
nitrate
and
nitrite.
Monitoring
requirements
follow
the
SMF
schedule
established
by
the
rule.
Under
the
SMF,
9­
year
compliance
cycles
were
established;
the
first
began
on
January
1,
1993,
and
ends
December
31,
2001.
The
next
cycle
begins
on
January
1,
2002,
and
ends
on
December
31,
2010.
Each
9­
year
cycle
consists
of
three,
3­
year
compliance
periods
(

Some
of

which
are
described
in
the
2001Arsenic
ICR
(
OMB
No.

INORGANIC
COMPOUNDS
This
section
summarizes
the
IOC
monitoring
requirements
for
the
first
3­
year
compliance
period
of
the
second
compliance
cycle
(
beginning
on
January
1,
2002),
as
described
in
40
CFR
141.23(
c).
For
the
purposes
of
monitoring
requirements,
the
IOCs
regulated
under
Phases
II
and
IIB
are
asbestos,
barium,
cadmium,
chromium,
fluoride,
mercury,
nitrite,
nitrate,
and
selenium.
The
IOCs
regulated
by
Phase
V
are
antimony,
beryllium,
cyanide,
and
thallium.
The
MCL
and
MCLG
for
nickel,
which
was
initially
included
as
part
of
Phase
V,
were
remanded
on
February
9,
1995.
This
means
that,
while
many
water
suppliers
continue
to
monitor
nickel
levels
in
their
water,
there
is
currently
no
EPA
legal
limit
on
the
amount
of
nickel
in
drinking
water.
Arsenic
is
regulated
under
the
1976
standards
for
IOCs.
12
During
each
3­
year
compliance
period,
ground
water
systems
must
take
one
sample
at
each
sampling
point.
Surface
water
systems
must
take
one
sample
annually
at
each
sampling
point.
If
results
from
any
sampling
events
are
above
the
MCL,
the
PWS
must
begin
quarterly
sampling
during
the
next
calendar
quarter.
The
PWS
must
continue
quarterly
sampling
until
the
State
determines
that
the
samples
are
reliably
and
consistently
below
the
MCL
based
on
at
least
two
consecutive
quarterly
samples
for
ground
water
systems
and
four
consecutive
quarters
for
surface
water
systems.
Once
the
samples
are
reliably
and
consistently
below
the
MCL,
ground
water
systems
are
then
required
to
sample
triennially,
and
surface
water
systems
must
sample
annually.

After
three
consecutive
sampling
rounds
without
detection,
a
PWS
may
apply
to
the
State
for
a
waiver.
Should
the
State
grant
a
waiver,
the
PWS
is
required
to
sample
only
once
every
nine
years.
IOC
waivers
must
be
renewed
every
nine
years.
Waivers
are
not
available
for
nitrate
or
nitrite
monitoring.

VOLATILE
ORGANIC
COMPOUNDS
This
section
summarizes
VOC
monitoring
requirements
for
the
first
3­
year
compliance
period
of
the
second
compliance
cycle
(
beginning
January
1,
2002),
as
described
in
40
CFR
141.24(
f).

For
VOCs,
surface
water
systems
must
take
one
sample
annually
at
each
sampling
point.
During
each
3­
year
compliance
period,
ground
water
systems
must
take
one
sample
at
each
sampling
point.
If
any
sample
exceeds
the
method
detection
limit
(
MDL)
of
0.0005
mg/
l,
the
PWS
must
begin
quarterly
monitoring
during
the
next
calendar
quarter.
Quarterly
sampling
must
continue
until
the
State
determines
that
the
samples
are
reliably
and
consistently
below
the
MCL
based
on
at
least
two
consecutive
quarterly
samples
for
ground
water
systems
and
four
consecutive
quarters
for
surface
water
systems.
However,
if
the
detection
that
triggered
the
increased
sampling
exceeds
the
MCL,
the
PWS
must
take
a
minimum
of
four
consecutive
quarterly
samples,
regardless
of
whether
it
is
served
by
ground
water
or
surface
water.
Once
the
samples
are
reliably
and
consistently
below
the
MCL,
the
State
may
reduce
the
sampling

frequency
to
once
per
year,
provided
repeat
sampling
is
conducted
during
the
calendar
quarter
that
previously
yielded
the
highest
analytical
result.

Systems
may
apply
to
the
State
for
a
waiver
after
3
years
of
annual
sampling
without
a
VOC
detection.
The
maximum
waiver
period
for
ground
water
sampling
points
is
6
years.
The
initial
waiver
must
be
renewed
within
the
first
3
years
of
issuance,
but
subsequent
waivers
may
be
renewed
at
the
end
of
the
6­
year
period.
A
ground
water
system
must
collect
one
sample
within
the
first
compliance
period
and
at
least
one
sample
during
each
6­
year
waiver
period.
For
surface
water
systems,
the
maximum
waiver
period
is
3
years,
but
there
is
no
minimum
Federal
sampling
frequency.
The
State
determines
the
sampling
schedule
for
surface
water
systems
with
a
3­
year
waiver.

SYNTHETIC
ORGANIC
COMPOUNDS
This
section
summarizes
the
SOC
monitoring
requirements
for
the
first
3­
year
compliance
period
of
the
second
compliance
cycle
(
beginning
January
1,
2002),
as
described
in
40
CFR
141.24(
h).

Systems
serving
more
than
3,300
people
are
required
to
take
two
SOC
samples
every
3
years.
For
systems
that
serve
fewer
than
3,300
people,
one
sample
is
required
every
3
years.
If
a
contaminant
is
detected
at
any
sampling
point,
the
water
system
must
begin
quarterly
sampling
during
the
next
calendar
quarter.
Quarterly
sampling
must
continue
until
the
State
determines
that
the
samples
are
reliably
and
consistently
below
the
MCL
based
on
at
least
two
consecutive
quarterly
samples
for
ground
water
systems
and
four
consecutive
quarters
for
surface
water
systems.
However,
if
the
detection
that
triggered
the
increased
sampling
exceeds
the
MCL,
then
the
PWS
must
take
a
minimum
of
four
consecutive
quarterly
samples,
regardless
of
whether
it
is
served
by
ground
water
or
surface
water.
Once
the
samples
are
reliably
and
consistently
below
the
MCL,
the
State
may
reduce
the
sampling
frequency
to
once
per
year,
provided
repeat
sampling
is
conducted
during
the
calendar
quarter
that
previously
yielded
the
highest
analytical
result.

After
3
years
of
annual
monitoring
without
SOC
detections,
systems
may
apply
for
a
waiver.
Waivers
are
effective
for
one
compliance
period
(
3
years).
They
must
be
renewed
in
each
subsequent
compliance
period,
or
the
system
must
return
to
the
sampling
frequency
specified
for
its
size.
Under
Federal
regulations,
systems
with
a
waiver
are
not
required
to
sample.

Unregulated
Contaminant
Monitoring
Rule,
Lists
1

Appendix
D
contains
the
ICRs
developed
for
the
Unregulated

Rule
List
1
and
List
2
contaminants.
As
these
ICRs
indicate,
SDWA,
as
amended
in
1996,
requires
the
Agency
to
develop
an
Unregulated
Contaminant
Monitoring
Regulation.
The
requirements
for
unregulated
contaminant
monitoring
were
first
established
by
the
1986
Amendments
to
the
SDWA
and
were
included
as
part
of
the
Phase
I
chemical
regulation
under
40
CFR
Parts
141.40(
a)­(
e).
The
Phase
II
regulation
supercedes
the
Phase
I
rule.

Section
1445(
a)
of
the
SDWA
1996
Amendments
substantially
revises
unregulated
contaminant
monitoring.
The
new
program
includes:
(
1)
a
new
list
of
contaminants
(
i.
e.,
the

and
(
4)
consumer
notification
regarding
of
the
availability
of

The
1996
Amendments
limit
the
number
of
contaminants
that
can
be
on
the
UCMR
List
to
30
or
fewer,
require
that
only
a
representative
number
of
systems
serving
a
population
of
10,000
or
fewer
people
be
required
to
monitor,
and
require
that
EPA
pay
reasonable
sample
analysis
costs
for
this
representative
sample
of
systems.

4)
1976
Radionuclides
Rule
and
2000
Radionuclides
Rule
Appendix
E
contains
the
ICR
developed
for
the
2000
Radionuclides
Rule.
As
the
ICR
indicates,
in
1976
EPA
promulgated
National
Interim
Primary
Drinking
Water
Regulations
(
NIPDWRs)
for
three
categories
of
radionuclides:
gross
alpha
particle
activity,
combined
radium­
226
and
radium­
228,
and
gross
beta
particle
and
photon
radioactivity.
The
1976
NIPDWRs
for
these
radionuclides
regulated
 

Gross
alpha
at
15
picoCuries
per
liter
(
pCi/
L)(
excluding
radon
and
uranium).


Radium­
226
and
radium­
228
combined
at
5
pCi/
L.


Beta/
photon
emitters
at
a
4
millirem
(
mrem)
dose
of
radioactivity.

The
1986
SDWA
amendments
identified
83
contaminants
for
the
Agency
to
regulate,
including
the
currently
regulated
radionuclides
that
lacked
MCLGs,
and
two
additional
radionuclides,
uranium
and
radon.
Also,
the
1986
amendments
declared
the
1976
interim
standards
to
be
NPDWRs.

On
December
7,
2000,
EPA
promulgated
a
revised
radionuclides
regulation,
which
becomes
effective
on
December
8,
2003.
The
new
rule
completely
supercedes
the
requirements
established
in
the
original
1976
Rule.

2000
Radionuclides
Rule,
which
is
applicable
only
to

Maintains
the
1976
MCL
of

Maintains
the
beta/
photon
screening
levels
set
in
the
1976
Rule
for
vulnerable
systems
(
as
deemed
by
the
State).
Surface
water
systems
serving
greater
than
100,000
persons
will
no
longer
be
required
to

they
are
deemed

If
a
PWS
applies
disinfectants
at
more
than
one
point
prior
to
the
first
customer,
it
must
determine
the
CT
of
each

to
determine
the

Rule
The

TTHM
standard
applies
only
to
surface

and
ground

CWSs
serving
at
least
10,000
people
that
add
a
disinfectant
to
the
drinking
water
during
any
part
of
the
treatment
process.
At
their
discretion,
States
may
extend
coverage
to
smaller
PWSs;
however,
most
States
have
not
exercised
this
option.
Monitoring
requirements
are
detailed
in
40
CFR
141.30.

The
Stage
1
DBPR
lowers
the
MCL
for
TTHM,
the
only
group
of
DBPs
regulated
previously.
Specifically,
the
MCL
of
0.10
mg/
L
is
now
0.080
mg/
L.
As
a
result,
after
December
31,
2001,
§
141.64
supersedes
§
141.12,
to
reflect
this
change.
Also
beginning
on
January
1,
2004,
the
Stage
1
DBPR
extends
the
requirements
to
systems
serving
fewer
than
10,000
people
and
NTNCWSs.

Agency
Activities
As
part
of
its
supervisory
responsibility,
EPA
maintains
SDWIS
and
evaluates
SDWIS
data
to
determine
system
compliance.
EPA
personnel
also
reformat,
distribute,
and
store
these
data
for
a
number
of
uses,
including
responding
to
Congressional
and
public
inquiries.
EPA
also
oversees
the
EPA
Regional
and
State
programs,
provides
technical
assistance,
and
develops
policies
designed
to
ensure
consistent
program
implementation.
EPA
officials
serve
as
respondents
when
testifying
to
Congress
on
the
PWSS
Program
or
in
the
courts
for
enforcement
actions.

EPA's
requirements
are
outlined
in
Exhibit
5
below.
Most
of
the
burden
and
costs
for
these
activities
are
addressed
in
the
PWSS
Program
ICR
(
OMB

of
the
PWSS
Program
ICR
contains
additional
detail
regarding
the
activities
supported
by
the
collection
of
SDWIS
data
described
above.
However,
under
the
UCMR,
EPA
does
incur
some
cost
for
activities
including
implementation
of
a
small
system
testing
program,
coordination
of
onsite
monitoring
for
Index
systems,
and
evaluation
of
data
for
assessment
monitoring
and
screening
surveys.

EPA
will
also
conduct
primacy
activities
in
States
and
territories
that
do
not
have
primacy.
Specifically,
EPA
will
be
involved
in
the
following
activities
 

Mobilization,

In
the
next
few
years,
EPA
anticipates
a
substantial
reduction
in
the
burden
and
cost
associated
with
reporting
data
because
of
increased
efficiency
of
electronic
reporting
by
PWSs
and
State
agencies.
Laboratories
are
developing
the
ability
to
report
monitoring
data
directly
to
primacy
agencies.

Collection
Methodology
and
Management
On
a
quarterly
basis,
primacy
agencies
must
report
data
to
EPA,
including
new
data
and
any
revisions
or
corrections
to
existing
data.
This
information
is
maintained
in
SDWIS,
which
contains
the
following
 
°
Inventory
data
for
each
PWS.
°
Violations.
°
Enforcement
actions
and
some
follow­
up
activity.
°
Variances
and
exemptions.

Primacy
agencies
transmit
SDWIS
data
to
EPA
both
manually
and
electronically.
In
the
District
of
Columbia,
Wyoming,
and
Indian
Lands
(
except
for
the
Navajo
Nation,
which
has
primacy),
results
of
system
samples
are
sent
directly
to
the
EPA
Region.
Virtually
all
SDWIS
data
are
reported
electronically
by
the
primacy
agency.
17
The
UCMR
requires
systems
to
report
some
data
in
addition
to
that
currently
required
by
§
141.35
and
requires
that
all
data
are
submitted
in
electronic
format.
UCMR
allows
laboratories
to
report
data
directly
to
EPA,
but
clarifies
that
systems
are
ultimately
responsible
for
timely
reporting.

SDWIS
data
support
a
number
of
rule
implementation
and
program
management
activities,
which
include
the
following
 

Tracking
the
status
of
PWSs
that
are
in
SNC.
This
information
is
provided
to
the
OECA,
as
part
of
the
Reporting
for
OECA
Priorities.
These
data
provide
senior
management
with
information
on
trends
in
drinking
water
enforcement.


Supporting
data
verification.
EPA
Regions
undertake
an
extensive
review
of
SDWIS
data
 
the
primary
purposes
of
which
is
to
assess
the
quality
of
data
and
recommend
any
necessary
changes
in
collection
or
reporting
methodologies.

$
Promoting
consistent
national
program
implementation.
The
process
of
data
verification
provides
insights
into
the
primacy
agency's
interpretation
of
regulations.
Such
information
supports
fair
and
consistent
SDWA
implementation
and
enforcement.

With
the
exception
of
UCMR,
all
costs
for
data
management
activities
are
addressed
in
the
PWSS
Program
ICR.
Section

of

(
RFA).

5(
c)
Small
Entity
Flexibility
In
developing
chemical
monitoring
rules
contained
in
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.
18

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.


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
of
all
rules
that
have
a
"
significant
economic
impact
on
a
substantial
number
of
small
entities."
This
ICR
is
not
associated
with
new
rules.
Therefore,
this
ICR
is
not
subject
to
the
SBREFA.
When
the
initial
Stage
1
DBPR
ICR
was
prepared
for
the
initial
implementation
phase
of
the
rule,
EPA
completed
an
RFA
because
it
had
determined
that
the
rule
would
have
a
significant
impact
on
small
systems.

However,
EPA
has
made
significant
efforts
to
minimize
the
burden
for
all
respondents,
particularly
for
small
entities.
In
setting
both
MCLs/
MRDLs
and
monitoring
requirements,
EPA
has
been
able
to
minimize
burden
for
small
entities
in
the
following
waysC
1)
Stage
1
Disinfectants
and
Disinfection
Byproducts
Rule
EPA
has
taken
steps
to
minimize
the
burden
on
small
PWSs.
These
measures
include
lower
monitoring
frequency
for
small
systems,
reducing
monitoring
frequency
for
systems
consistently
and
reliably
below
the
MCLs
and
MRDLs,
and
extending
the
compliance
date
for
small
systems
to
5
years
after
promulgation
of
the
rule.

2)
Chemical
Phase
Rules
For
the
contaminants
regulated
under
the
Phase
II
regulation,
the
provisions
established
in
the
SMF
are
intended
to
minimize
burden
on
small
entities
by
allowing
systems
to
composite
as
Disinfectants/
Disinfection
Byproducts,
Chemical,
and
Radionuclides
ICR

50
many
as
five
samples
and
by
allowing
States
to
grant
waivers,
which
reduce
or
eliminate
monitoring
requirements.

For
Phase
V
chemicals,
EPA
has
taken
steps
to
minimize
the
burden
on
PWSs
(
in
addition
to
the
provisions
listed
for
Phase
II
contaminants)
by
allowing
systems
serving
fewer
than
3,300
people
to
composite
among
different
systems
provided
the
five
sample
limit
is
maintained.
Sample
collection
has
also
been
simplified
by
allowing
the
same
sampling
locations
to
be
used
for
all
source
water­
related
monitoring.

3)
Unregulated
Contaminant
Monitoring
Rule,
Lists
1
and
2
EPA
has
estimated
the
impact
of
the
UCMR
and
concluded
that
the
impact
on
small
water
systems
will
not
be
significant.
The
rationale
for
this
conclusion
is
that
EPA
plans
to
pay
the
full
costs
of
shipping
and
testing
samples
for
small
systems
and
does
not
plan,
under
any
scenario,
to
ask
systems
to
pay
these
costs.
Thus,
the
costs
to
these
systems
will
be
limited
to
the
labor
hours
associated
with
collecting
a
sample
and
preparing
it
for
shipping.
System
costs
under
both
a
"
Full
Assessment
Monitoring
Implementation"
and
"
Limited
Assessment
Monitoring
Implementation"
scenario
were
estimated
to
ensure
that
small
systems
would
not
incur
significant
economic
impacts
under
any
circumstances.
See
Appendix
D
of
the
UCMR
ICR
for
a
detailed
description
of
these
scenarios.

4)
1976
Radionuclides
Rule
and
2000
Radionuclides
Rule
The
monitoring
requirements
for
radionuclides
apply
only
to
CWSs
and
specify
different
monitoring
frequencies
depending
on
the
type
of
source
water.
Ground
water
systems
have
less
stringent
monitoring
requirements
and
since
most
small
systems
use
ground
water,
the
rule
imposes
less
burden
on
such
systems.
Specifically,
ground
water
systems
must
sample
at
least
once
every
4
years,
while
surface
water
systems
must
take
four
consecutive
quarterly
samples
once
every
4
years.
Additionally,
gross
beta
analysis
is
required
only
for
surface
water
systems
serving
at
least
10,000
people.

5)
Total
Trihalomethanes
Rule
The
initial
1979
TTHM
standard
applies
only
to
CWSs
that
use
surface
water
or
ground
water
that
serve
at
least
10,000
people,
and
that
add
a
disinfectant
to
the
drinking
water
during
any
part
of
the
treatment
process.
At
their
discretion,
States
may
extend
coverage
to
smaller
PWSs;
however,
most
States
have
not
exercised
this
option.
Starting
in
2004,
the
Stage
1
DBPR
completely
supercedes
the
TTHM
Rule,
eliminating
a
separate

6)
Disinfectant
Residual

under
the
SWTR
The
rule
allows
systems
serving
3,300
and
fewer
to
substitute
grab
sampling
for
continuous
disinfectant
residual
monitoring.
This
enables
small
systems
to
avoid
large
capital
costs
associated
with
continuous
monitoring
equipment.
Further,
the
number
of
daily
grab
samples
required
for
measuring
the
disinfectant
residual
is
directly
related
to
the
system's
size.
Systems
serving
500
or
fewer
people
are
required
to
take
one
sample,
while
systems
serving
2,501
to
3,300
people
are
required
to
take
four
samples.

This

the
assumptions
used
to
estimate
burden
and
costs
and
describes
the
change
in
annual
burden,
as
compared
with
the
current
OMB
annual
burden
inventory.
This
ICR
updates
the
annual
burdens
and
costs
associated
with
these
rulemakings
for
years
2002
through
2004.

For
this
update,
many
assumptions
were
revised
based
on
program
changes
and
welldocumented
changes
in
some
data.
EPA
is
committed
to
accurately
characterizing
the
burden
and
costs
of
rules
it
promulgates.
Consequently,
it
has
maintained
communication
with
interested
stakeholders.
Based
on
the
information
gathered
during
consultations
with
these
stakeholders,
EPA
has
refined
some
of
the
assumptions
for
calculating
the
burden
and
costs
associated
with
implementing
the
drinking
water
regulations
contained
in
this
ICR.

Specifically,
EPA
noted
several
inconsistencies
in
assumptions
used
to
estimate
burden
and
costs
in
previous
ICRs.
To
provide
a
comparable
basis
on
which
to
calculate
the
requirements
addressed
by
the
DDBP/
Chem/
Rads
ICR
and
to
address
inconsistencies,
EPA
applied
uniform
assumptions
to
all
rules.
The
categories
of
assumptions
are
listed
below.

°
Labor
rates
 
for
PWSs,
a
mean
hourly
rate
of
$
15.02
with
an

level
burden
assumptions
were
carried
forward
from
previous
ICRs.
However,
if
updated
data
were
available
(
e.
g.,
system
inventories),
those
data
were
used
in
burden
calculations.
Appendices
F
through
K
show
the
assumptions
and
detailed
burden
calculations
for
each
rule.
The
following
further
describes
the
bases
for
the
burden
estimates
for
each
rule.

1)
Stage
1
Disinfectants
and
Disinfection
Byproducts
Rule
Activities
associated
with
the
Stage
1
DBPR
account
for
0.63
million
annual
burden
hours.
The
assumptions
used
to
calculate
the
Stage
1
DBPR
burden
are
based
largely
on
assumptions
from
the
September
1998
Information
Collection
Request
for
the
National
Primary
Drinking
Water
Regulations:
Stage
1
Disinfectants
and
Disinfection
Byproducts
Rule
(
Stage
1
DBPR
ICR).
The
burden
for
systems
includes
startup
activities
and
monitoring.
The
startup
activities
include
reading
the
rule,
conducting
training,
and
developing
monitoring
plans.
Only
systems
serving
10,000
or
fewer
people
have
a
startup
burden
for
the
2002­
2004
ICR
period
because,
based
on
the
rule's
implementation
schedule,
the
startup
burden
for
systems
serving
at
least
10,000
people
was
included
in
the
prior
ICR.
The
specific
burden
for
monitoring
includes
the
following
 

Paired
TTHM/
HAA5

Alkalinity
and
paired
TOC

Bromate

Chloride
Dioxide

Chlorite
(
both
daily
and
monthly
monitoring)


Chlorine
or
chloramines
(
in
the
distribution
system)
22
At
this
point,
reduced
monitoring
burden
was
not
estimated
for
the
above
contaminants,
with
the
exception
of
alkalinity
and
paired
TOC
monitoring,
which
carried
forward
reduced
monitoring
rate
estimates
from
the
September
1998
Stage
1
DBPR
ICR.

the
reasons
for
changes
between
the

also
includes
a
correction
for
an
error
in
the
annual
burden
hours
reported
for
IOC
monitoring
in
the
1993
PWSS
Program
ICR.
A
spreadsheet
error
resulted
in
an
overestimation
of
IOC
burden
of
over
1.3
million
hours
annually.
Estimates
and
adjustments
described
in
this
paragraph
refer
to
the

of
this

2)
Chemical
Phase
Rules
Activities
associated
with
the
Chemical
Phase
Rules
account
for
a
burden
of
0.46
million
hours
per
year.
The
burden
estimate
includes
routine
and
reduced
sampling
for
IOCs,
VOCs,
and
SOCs
under
the
schedules
dictated
by
the
SMF.
The
assumptions
used
to
calculate
the
Chemical
Phase
Rule
burden
are
based
on
assumptions
from
the
1993
PWSS
Program
ICR,
which
maintained
most
assumptions
and
burden
estimates
from
the
individual
ICRs
for
the
Phase
II,
IIB,
and
V
rules.
However,
the
waiver
rate
assumptions
have
been
adjusted
to
more
accurately
reflect
actual
waiver
issuance
rates.
Specifically,
the
previous
Chemical
Phase
Rule
burden
calculations
assumed
that
more
systems
would
qualify
and
apply
for
waivers.
Consequently,
the
amount
of
required
sampling
and
associated
burden
is
higher
in
the
DDBP/
Chem/
Rads
ICR
due
to
this
downward
adjustment
in
waiver
issuance
rates.
Section
6(
f)
describes
the
reasons
for
changes
between
the
burden
reported
in
the
1993
PWSS
Program
ICR
and
the
DDBP/
Chem/
Rads
ICR.

Total
annual
burden
for
PWSs
for
the
UCMR
for
List
1
and
List
2
contaminants
is
estimated
to
be
0.006
million
hours.
Included
in
this
burden
is
startup

for
reading
the
regulation
and
guidance
materials,
and
the
monitoring,
reporting,
and
recordkeeping
burden
for
the
List

assumptions
for
this

were
carried
forward
from
the
August

and
the

Reasons
for
changes
in

are
summarized
in
Section

4)
1976
Radionuclides
Rule
and
2000
Radionuclides
Rule
For
the
1976
Radionuclides
Rule
annual
PWS
burden
is
estimated
to
be
0.009
million
hours.
This
number
was
extracted
from
Table
6­
4
of
the
September
2000
Information
Collection
Request
for
National
Primary
Drinking
Water
Regulations:
Radionuclides
(
2000
Radionuclides
ICR).
The
2000
Radionuclides
ICR
re­
estimated
the
annual
baseline
burden
for
the
1976
Radionuclides
Rule
at
14,065
hours.
However,
the
revised
estimate
of
the
1976
Radionuclides
monitoring
burden
is
included
in
this
ICR
for
the
first
2
years
only
(
2002
and
2003).
Beginning
in
January
2004,
all
radionuclides
monitoring
will
be
addressed
by
the
2000
Radionuclides
Rule
requirements,
which
completely
absorb
and
augment
the
requirements
originally
established
in
Disinfectants/
Disinfection
Byproducts,
Chemical,
and
Radionuclides
ICR
November
29,
2001
24
In
calculating
burden
for
this
ICR,
EPA
used
the
simplified
assumption
that
the
new
Radionuclides
Rule
becomes
effective
on
January
1,
2004
(
rather
than
December
8,
2003).

55
1976
Rule.
24
Only
28,130
hours
from
the
1976
Radionuclides
Rule
(
2
x
14,065
annual
burden
hours)
are
included
in
the
DDBP/
Chem/
Rads
ICR,
resulting
in
an
average
annual
burden
of
9,377
annually
(
28,130/
3).

For
this
ICR,
annual
PWS
burden
for
the
2000
Radionuclides
Rule
is
estimated
to
be
0.23
million
hours,
which
is
based
on
burden
assumptions
contained
in
the
September
2000
Radionuclides
ICR.
Burden
estimates
for
the
first
year
(
2001)
of
startup
activities
for
2000
Radionuclides
requirements
are
covered
under
the
existing
ICR.
Thus,
the
DDBP/
Chem/
Rads
ICR
includes
burden
starting
in
2002.
This
burden
includes
2
years
of
startup
activities
(
for
years
2002
and
2003),
and
one
year
of
monitoring
activities
(
for
year
2004).
To
compensate
for
this
change,
the
2000
Radionuclides
ICR,
which
does
not
expire
until
2003,
should
be
cancelled
once
the
burden
has
been
added
to
the
DDBP/
Chem/
Rads
ICR.
This
change
will
avoid
doublecounting
of
the
burden.

Monitoring
burden
is
for
the
following
contaminants
 

Gross

Total
Trihalomethanes
Rule
Implementation
of
the
TTHM
Rule
is
expected
to
result
in
an
annual
PWS
burden
of
0.02
million
hours.
This
burden
is
for
monitoring
during
2002
and
2003
by
ground
water
systems
serving
at
least
10,000
people.
No
burden
for
Year
2004
is
calculated
for
the
TTHM
Rule
because
the
Stage
1
DBPR
completely
absorbs
the
TTHM
requirements
and
expands
them
to
address
systems
serving
fewer
than
10,000
people
and
NTNCWSs.

For
States,
the
annual

Rule
For
the
1976
Radionuclides
Rule,
annual
State

is
estimated
to
be
0.001
million
hours.
This
estimate
is
derived
from
the
September
2000
Radionuclides
ICR
and
is
a
function
of
the
number
of
analyses
performed
by
PWSs.
Specifically,
burden
is
calculated
for
primacy
agency
staff
for
recordkeeping,
reporting,
and

The
annual
State

Burden
is
calculated

For
consistency,
this
rate
has
been
inflated
to
September
2000
dollars
using
the
Employment
Cost
Index.
The
inflated
rate
is
$
15.02.
In
addition,
60
percent
overhead
was
assumed,
bringing
the
loaded
rate
to
$
24.03
in
September
2000
dollars.

In
addition
to
labor
costs,
there
are
O&
M
costs
associated
with
the
each
of
the
rules
covered
by
this
ICR.
These
O&
M
costs
reflect
non­
labor
costs
associated
with
sample
analysis
for
each
of
the
rules.
These
costs
vary
by
rule
according
to
the
frequency
and
cost
of
a
particular
analysis.

In
addition
to
O&
M
costs,
the
requirements
of
one
rule
(
SWTR)
result
in
capital
costs
to
affected
PWSs.
Capital
costs
are
incurred
to
buy
and
replace
monitoring
equipment
necessary
for
on­
site
analysis
of
disinfectant
residuals
and
water
pH.
Capital
costs
are
based
on
vendor
estimates
for
both
in­
line
and
portable
equipment,
as
required
by
regulations.

Cost
to

Exhibit

shows
that
the
annual
cost
to
primacy
agencies
are
estimated
at
approximately
$
52.9
million,
which
is
comprised
exclusively
of
labor
costs.
The
labor
costs
are
based
on
an
average
full
time
equivalent
(
FTE)
cost
of
$
60,086
including
overhead,
which
equates
to
approximately
$
28.89
per
hour.
25
This
rate,
which
has
been
inflated
to
year
2000
dollars,
is
based
on
the
rate
($
55,000)
suggested
by
the

that
developed
the

Model
in
1997.

Estimating
Respondent
Universe
and
Total
Burden
and
Costs
Respondents
for
this
ICR
include
both
PWSs
and
States
or
other
primacy
agencies.
This
ICR
estimates
that
the
number
of
PWS
respondents
is
167,837
existing
PWSs.
26
However,
all
PWSs
are
not
necessarily
subject
to
each
of
the
information
collection
requirements
contained
in
this
ICR.
The
regulations
associated
with
each
rule
identify
the
numbers
and
types
of
PWSs
that
are
subject
to
each
particular
provision.
In
addition
to
the
PWS
respondents,
this
ICR
assumes
57
primacy
agencies
(
50
States
plus
D.
C.,
U.
S.
Territories,
and
the
Navajo
Nation).
27
Therefore,
the
total
number
of
respondents
is
167,894.

The
total
costs
and
burden
for
these
respondents
are
summarized
in

explains
the
correction
of
a

This
discrepancy
is
a

Burden
associated
with
the
Stage

Disinfection
Byproducts
Rule.
The
annual
burden
estimated
in
the
1998
Stage

DBPR
is
314,471
hours.
This
includes
21,367
annual
burden
hours
for
PWSs
and
293,104
annual
burden
hours
for
primacy
agencies
(
Figure

of
the
1998
Stage

DBPR
ICR).
This
burden
serves
as
the
baseline
burden
for
the
DDBP/
Chem/

ICR.
The

is
being
renamed
the

Burden
associated
with
Chemical
Monitoring.
The
1993

This
includes
1,694,663

Although
both
UCMR

are
included
in
the
restructuring,
the
majority
of
the

stems
from
the
1999

contains
only
100
additional

beyond
those

30
Although
the

hours
and
costs
for

these
burdens
and

are
not
counted

Burden
associated
with
Radionuclides.
The
1993

includes
a
total
of
5,637
hours
per
year
for
Radionuclides
Rule
activities,
reflecting

includes
an
annual

Correction
for
Discrepancy
in
Current
ICR
Inventory
During
the
restructuring
and
recalculation
process
undertaken
with
this
ICR,
a
discrepancy
was
noted
in
the
existing
ICR
burden
inventory.
The
discrepancy
was
found
in
the
annual
burden
reported
for
the
Chemical
Phase
Rules
in
the
1993
PWSS
Program
ICR.

PWSS

a
spreadsheet
calculation
error
that
caused
significant
overestimation
of
the
burden
for
IOC
monitoring
under
the
Phase
II
chemical

rule.
Exhibit

of
the
1993
PWSS
program
ICR
lists
an
annual
burden
for
IOC
monitoring
of
1,549,778
hours.
Analysis
of
the
spreadsheets
that
serve
as
a
source
for
the
numbers
in
this
exhibit
reveal
that
this
estimate
is
incorrect.
In
the
spreadsheet
calculation
that
feeds
into
Exhibit
8
of
the
1993
PWSS
Program
ICR,
the
annual
costs
for
nitrites
were
transcribed
in
the
annual
burden
column
and
carried
into
the
final
annual
burden
displayed
in
Exhibit
8
of
the
PWSS

Entering
the
correct
annual
burden
for
nitrites
results
in
a
total
annual

for
IOCs
of
243,810
hours,
a
difference
of

Other
Burden
Adjustments
The
remaining
changes
in
burden
are
a
result
of
adjustments
to
individual
rule
burden
calculations.
Changes
in
calculated
burden
are
a
result
of
updating
relevant
baseline
information
for
each
rule
with
the
most
current
and
accurate
information
available
(
e.
g.,
PWS
inventories).
Where
appropriate,
estimated
violation,
waiver,
and
other
associated
rates
have
also
been
updated
to
reflect
current
information
on
rule
compliance.
For
the
Stage
1
DBPR,
a
large
increase
in
annual
burden
reflects
movement
from
startup
activities
to
the
actual
monitoring
compliance
period.
For
primacy
agency
activities,
changes
in
the
levels
of
rule­
specific
activity
tend
to
mirror
the
changes
in
PWS
activities.
Exhibits
13
and
14
summarize
reasons
for
these
changes
and
quantify
the
changes
by
rule.
Burden
adjustments
associated
with
PWS
activities
resulted
in
a
burden
increase
of
1.17
million
hours
and
are
detailed
in
Exhibit

Burden

The
increase
in

is
attributable
to
a
combination
of
updated
system

the
requirements
of
the
particular
SMF
compliance
period,
and
reevaluation
of
actual

The
increase

all
of
the
burden
for
the
2000
Radionuclides
Rule
is
attributable
to

The
decrease
in

is
attributable
to
the
completion
of
some
startup
activities
under
the
previous
ICR
(
i.
e.,
2001
startup
burden
is
not
included).
For
