Adopted Rule.
Final Order.
Order of the Board
(by J.
Anderson):
Pursuant to Sections 17.5 of the Environmental Protection
Act
(Act), the Board is proposing to amend the Safe Drinking
Water Act
(SDWA)
regulations.
Section 17.5 provides for quick adoption of regulations
which are “identical in substance” to federal regulations and
that Title VII of the Act and Section 5 of the Administrative
Procedure Act
(APA)
shall not apply.
Because this rulemaking is
not subject to Section
5 of the APA,
it is not subject to first
notice or to second notice review by the Joint Committee on
Administrative Rules
(JCAR).
The federal SDWA regulations are
found at 40 CFR 141 and 142.
This rulemaking updates SDWA rules
to correspond with major federal amendments more fully outlined
in the accompanying Opinion.
This proposed order
is supported by a proposed opinion
adopted on the same day.
The Board will receive public comment
on the proposal for a period of 45 days following its publication
in the Illinois Register.
The complete text of the proposed
rules follows.
IT IS SO ORDERED.
I, Dorothy N. Gunn,
Clerk of the Illinois Pollution Control
Board, do hereby certify that the above order was adopted on the

2)
The Board may grant a variance from the additional
State requirements in this Part without following
this Section.
b)
As part of the showing of arbitrary or unreasonable
hardship, the supplier shall demonstrate that:
1)
Because of characteristics of the raw water
sources that are reasonably available to the
system, the supplier cannot meet the MCL or other
requirement; and
2)
The system has applied BAT as identified in
Subpart G of this Part.
BAT may vary depending
on:
A)
The number of persons served by the system;
B)
Physical conditions related to engineering
feasibility; and
C)
Costs
of compliance; and
3)
The
variance will not result in an unreasonable
risk to health,
as defined
in subsection
(g)
below.
c)
The Board will prescribe a schedule for:
1)
Compliance,
including increments
of progress,
by
the
supplier, with each MCL or other requirement
with respect to which the variance was granted,
and
2)
Implementation by the supplier of each additional
control measure for each MCL or other requirement,
during the period ending on the date compliance
with such requirement is required.
d)
A schedule of compliance will require compliance with
each MCL or other requirement with respect to which the
variance was granted as expeditiously as practicable.
e)
The Board will provide notice and opportunity for a
public hearing as provided in 35

coliform MCL is due to persistent growth of total
coliforms in the distribution system,
rather than
from fecal or pathogenic contamination,
from a
treatment
lapse or deficiency, or from a problem
in the operation or maintenance of the
distribution system.
2)
Or,
from
any of the treatment technique
requirements of Subpart B of this Part.
g)
As used in this Section and Section 611.112,
“unreasonable risk to health level”
(“URTH level”)
means the concentration of a contaminant that will
cause a serious health effect within the period of time
specified in the variance or exemption requested by a
supplier seeking to come into compliance by installing
the treatment required to reduce the contaminant to the
MCL.
URTH level determinations are made on the basis
of the individual contaminant,
taking into account:
the degree by which the level exceeds the MCL; duration
of exposure; historical data; and population exposed.
A risk to health is assumed to be unreasonable unless
the supplier demonstrates that there are costs
involved
that
clearly
exceed
the
health benefits to be derived.

Compliance with old
MCLs for inorganic chemicals is calculated pursuant to
Section 611.612.
Thc

BOARD NOTE:
Derived from 40 CFR 141.11(a)
(199+2,).
UCEPA has given an expiration date of December
7, 1~ii~
for the MCL for lead and January
1,
1993 for barium
because those are the effective dates for the federal
lead and copper

BOARD NOTE:
Derived from 40 CFR 141.11(b)
(199+2,).
This provision, which corresponds with
40 CFR 141.11, was formerly the only listing of
MCLs for inorganic parameters.
However, USEPA
added another listing of inorganic MCLs at 40 CFR
141.62 at 56 Fed. Reg.
3594
(Jan.
30,
1991).
Following the changing USEPA codification scheme
creates two listings of MCLs:
one at this Section
and one at Section 611.301.
This also causes
fluoride to appear in both the 40 CFR 141.11(b)
and 141.62(b)
listings with the same NCL.
The
impact of thc two listings arc distinct.Board has
deleted the corresponding fluoride MCL from this

(199+2,).
This incorporation includes no
later editions or amendments.
2)
Non-CWSs may exceed the MCL for nitrate to the
extent authorized by 40 CFR 141.11(d).
BOARD NOTE:
Derived from 40 CFR 141.11(d)
(199+2,).
Public Health regulations may impose a
nitrate limitation requirement.
Those regulations

The following supplementary condition applies to the
concentrations listed
in subsection
(b)
above:
Iron
and manganese:
1)
CWS suppliers that serve a population of 1000 or
less,
or 300 service connections or less,
are
exempt from the standards for iron and manganese.
2)
The Agency may, by special exception permit,
allow
iron and manganese in excess of the MCL
if
sequestration tried on an experimental basis
proves to be effective.
If sequestration is not
effective, positive iron or manganese reduction
treatment as applicable must be provided.
Experimental use of a sequestering agent may be
tried only if approved by special exception
permit.

This Subpart establishes a treatment
technique that includes requirements for corrosion
control treatment,
source water treatment,
lead
service line replacement, and public education.
These requirements are triggered,
in some cases,
bY lead and copper action levels measured in
samples collected at consumers’ taps.
~j
Definitions.
For the purposes of only this Subpart,
the following terms shall have the following meanings:
“Action level” means that concentration of lead or
copper in water computed Pursuant to subsection

The requirements in this Section apply to unfiltered PWS5 until
December 30,
1991, unless the Agency has determined prior to that
date that filtration is required.
The requirements in this
Section apply to filtered PWSs until June 29,
1993.
The
requirements in this Section apply to unfiltered PWSs that the
Agency has determined must install filtration, until June 29,
1993,
or until filtration is installed, whichever is later.
a)
Suppliers shall take samples at representative entry
point(s) to the distribution system at least once per
day, for the purposes of making turbidity measurements
to determine compliance with Section 611.320.
1)
If Public Health determines that a reduced
sampling frequency in a non—CWS will not pose a
risk to public health,
it may reduce the required
sampling frequency. The option of reducing the
turbidity frequency will be permitted only in
those suppliers that practice disinfection and
which maintain an active RDC in the distribution
system, and in those cases where Public Health has
indicated in writing that no unreasonable risk to
health existed under the circumstances of this
option.
2)
The turbidity measurements must be made in
accordance with the following methods,
incorporated by reference in Section 611.102:
A)
By the Nephelometric Method:
i)
Standard Methods:
Method 214A;
or
ii)

Method 180.1.
B)
Calibration of the turbidimeter must be made
either by the use of a formazin standard as
specified in the cited references, or a
styrene divinylbenzene polymer standard
(Ainco-AEPA-1 Polymer).
b)
If the result of a turbidity analysis indicates that
the maximum allowable limit has been exceeded, the
sampling and measurement must be confirmed by
resampling as soon as practicable and preferably within
one hour.
If the repeat sample confirms that the
maximum allowable limit has been exceeded, the supplier
of water shall report to the Agency within 48 hours.

MCLs
a)
Analyses for the purpose of determining compliance with
the old inorganic NCLs of Section 611.300 are required
as follows:
1)
Analyses for all CWSs utilizing surface water
sources must be repeated at yearly intervals.
2)
Analyses for all CWSs utilizing only groundwater
sources must be repeated at three—year intervals.
3)
This subsection corresponds with 40 CFR
141.23(1) (3)
(199~),which requires monitoring
for the repealed old MCL for nitrate at a
frequency specified by the state.
The Board has
followed the USEPA lead and repealed that old MCL.
This statement maintains structural consistency
with USEPA rules
4)
This subsection corresponds with 40 CFR

action.
•This authority exists through the
authorization of the Act,
n.ot therQugh federal
rules.
This statement maintains structural
consistency with USEPA rules.
b)
If the result of an analysis made under subsection
(a)
above indicates that the level of any contaminant
listed in Section 611.300 exceeds the old MCL, the
supplier shall report to the Agency within
7 days and
initiate three additional analyses at the same sampling
point within one month.
C)
When the average of four analyses made pursuant to
subsection
(b) above,
rounded to the same number of
significant figures as the old MCL for the substance in
question, exceeds the old MCL, the supplier shall
notify the Agency and give notice to the public
pursuant to Subpart T of this Part.
Monitoring after
public notification must be at a frequency designated
by the Agency by a SEP granted pursuant to Section
611.110 and must continue until the old MCL has not
been exceeded in two successive samples or until a
different monitoring schedule becomes effective as a
condition to a variance, an adjusted standard,
a site
specific rule, an enforcement action, or another SEP
granted pursuant to Section 611.110.
d)
This subsection corresponds with 40 CFR 141.23(o)
(199lZ), which pertains to monitoring for the repealed
old MCL for nitrate.
The Board has followed the USEPA
action and repealed that old MCL.
This statement
maintains structural consistency with USEPA rules.

the determination of sodium concentration
levels;
samples must be collected and analyzed annually for
CWS5 utilizing surface water sources in whole or in
part, and at least every three years for CWSs utilizing
solely groundwater sources. The minimum number of
samples required to be taken by the supplier is based
on the number of treatment plants used by the supplier,
except that multiple wells drawing raw water from a
single aquifer may, with the Agency approval, be
considered one treatment plant for determining the
minimum number of samples. The Agency shall require the
supplier to collect and analyze water samples for
sodium more frequently in locations where the sodium
content is variable.
b)
The CWS supplier shall report to the Agency the results
of the analyses for sodium within the first 10 days of
the month following the month in which the sample
results were received or within the first 10 days
following the end of the required monitoring period as
specified by SEP, whichever of these is first.
If more
than annual sampling is required the supplier shall
report the average sodium concentration within
10 days
of the month following the month in which the
analytical results of the last sample used for the
annual average was received.
C)
The CWS supplier shall notify the Agency and
appropriate local public health officials of the sodium
levels by written notice by direct mail within three
months. A copy of each notice required to be provided
by this subsection must be sent to the Agency within
10
days of its issuance.

The effectiveness
of the Section 611.311 MCL5 for aldicarb. aldicarb
sulfone, and aldicarb sulfoxide are
administratively stayed until the Board takes
further administrative action to end this stay.
However, suppliers must monitor for these three
SOC5 pursuant to Section 611.648.

Section 611.646
Phase
I and Phase II Volatile Organic
Contaminants
Monitoring of the Phase I VOCs and Phase II VOCs for the purpose
of determining compliance with the MCL must be conducted as
follows:
a)
Definitions.
As used in this Section:
“Detect” and “detection” means that the
contaminant of interest is present at a level
greater than or equal to the “detection limit”.
“Detection limit” means 0.0005 mg/L.
BOARD NOTE:
Derived from 40 CFR 141.24(f) (7),
(f)(11),
(f)(14)(i), and
(f)(20)
(1994~2). This is
a “trigger level” for Phase I VOC5 and Phase II
VOCs inasmuch as it prompts further action.
The
use of the term “detect” in this section is not
intended to include any analytical capability of
quantifying lower levels of any contaminant, or
the “method detection limit”.
Note, however that
certain language at the end of federal paragraph
(f) (20)
is capable of meaning that the “method
detection limit” is used to derive the “detection
limit”.
The Board has chosen to disregard that
language at the end of paragraph
(f) (20)
in favor
of the more direct language of paragraphs
(f) (7)
and
(f) (11).
“Method detection limit”, as used in subsections
(q) and
(t) below means the minimum concentration
of a substance that can be measured and reported
with 99 percent confidence that the analyte
concentration is greater than zero and is
determined from analysis of a sample in a given
matrix containing the analyte.
01 L~2-0260
131
BOARD NOTE:
Derived from 40 CFR 136, Appendix B
(l994~). The method detection limit is determined
by the procedure set forth in 40 CFR 136, Appendix
B.
See subsection
(t)
below.
b)
Required sampling.
Each supplier shall take a minimum
of one sample at each sampling point at the times
required in subsection
(u)
below.
C)
Sampling points.
1)
Sampling points for GWSs.
Unless otherwise
provided by SEP,
a GWS supplier shall take at
least one sample from each of the following
points:
each entry point that is representative
of each well after treatment.
2)
Sampling points for SWSs and mixed systems.
Unless otherwise provided by SEP,
a SWS or mixed
system supplier shall sample from each of the
following points:
A)
Each entry point after treatment; or
B)
Points in the distribution system that are
representative of each source.
3)
The supplier shall take each sample at the same
sampling point unless the Agency has granted a SEP
that designates another location as more
representative of each source, treatment plant,
or
within the distribution system.
4)
If a system draws water from more than one source,
and the sources are combined before distribution,
the supplier shall sample at an entry point during
periods of normal operating conditions when water
is representative of all sources being used.
BOARD NOTE:
Subsections
(b) and
(c)
above derived
from 40 CFR 141.24(f) (1) through
(f)(3) (199~).
d)
Each CWS and NTNCWS supplier shall take four
consecutive quarterly samples for each of the Phase I
VOCs,
excluding vinyl chloride, and Phase II VOCs
during each compliance period, beginning in the
compliance period starting January
1,
1993.
e)
Reduction to annual monitoring frequency.
If the
initial monitoring for the Phase I VOC5 and Phase II
VOCs as allowed in subsection
(r) (1) below has been
completed by December 31,
1992, and the supplier did
U
132
not detect any of the Phase
I VOCs,
including vinyl
chloride,
or Phase II VOCs, then the supplier shall
take one sample annually beginning January 1,
1993.
f)
GWS reduction to triennial monitoring frequency.
After
a minimum of three years of annual sampling, GWS
suppliers that have not previously detected any of the
Phase I VOC5,
including vinyl chloride, or Phase II
VOCs shall take one sample during each three—year
compliance period.
g)
A CWS or NTNCWS supplier that has completed the initial
round of monitoring required by subsection
(d) above
and which did not.detect any of the Phase I VOCs,
including vinyl chloride, and Phase II VOCs may apply
to the Agency for a SEP pursuant to Section 611.110
that releases it
from
the requirements of subsection
(e) or
(f)
above.
BOARD
NOTE:
Derived from 40 CFR 141.24(f) (7)
and
(f) (10) (199~).
Provisions concerning the term of the
waiver appear below in subsections
(i) and
(j)
below.
The definition of “detect”, parenthetically added to
the federal counterpart paragraph is in subsection
(a)
above.
h)
Vulnerability Assessment.
The Agency shall consider
the factors of Section 611.110(e)
in granting a SEP
from the requirements of subsections
(e)
or
(f) above
sought pursuant to subsection
(g)
above.
i)
A SEP issued to a GWS pursuant to subsection
(g)
above
is for a maximum of six years.
As a condition of a
SEP, the supplier shall, within 30 months after the
beginning of the period for which the waiver was
issued, reconfirm its vulnerability assessment required
by subsection
(h) above and submitted pursuant to
subsection
(g)
above,
by taking one sample at each
sampling point and reapplying for a SEP pursuant to
subsection
(g)
above.
Based on this application, the
Agency shall either:
1)
If it determines that the PWS meets the standard
of Section 611.610(e),
issue a SEP that reconfirms
the prior SEP for the remaining three-year
compliance period of the six—year maximum term;
or,
2)
Issue a new SEP requiring the supplier to sample
annually.
BOARD NOTE:
This provision does not apply to SWSs
0
1L~2-0262
133
and mixed systems.
j)
Special considerations for SEPs for SWS and mixed
systems.
1)
The Agency must determine that a SWS is not
vulnerable before issuing a SEP pursuant to a SWS
supplier.
A SEP issued to a SWS or mixed system
supplier pursuant to subsection
(g)
above is for a
maximum of one compliance period; and
2)
The Agency may require, as a condition to a SEP
issued to a SWS or mixed supplier, that the
supplier take such samples for Phase
I VOC5 and
Phase II VOCs at such a frequency as the Agency
determines are necessary, based on the
vulnerability assessment.
BOARD NOTE:
There is a great degree of similarity
between 40 CFR 141.24(f) (7), the provision
applicable to GWSs,
and 40 CFR 141.24(f) (10),
the
provision for SWSS.
The Board has consolidated
the common requirements of both paragraphs into
subsection
(g)
above.
Subsection
(j)
above
represents the elements unique to SWSs and mixed
systems, and subsection
(1)
above relates to GWSs.
Although 40 CFR 141.24(f) (7) and
(f) (10)
are
silent as to mixed systems, the Board has included
mixed systems with SWSs because this best follows
the federal scheme for all other contaminants.
k)
If one of the Phase I VOCs,
excluding vinyl chloride,
or Phase II VOCs is detected in any sample, then:
1)
The supplier shall monitor quarterly for that
contaminant at each sampling point that resulted
in a detection.
2)
Annual monitoring.
A)
The Agency shall grant a SEP pursuant to
Section 611.110 that allows a supplier to
reduce the monitoring frequency to annual at
a sampling point if it determines that the
sampling point is reliably and consistently
below the I4CL.
B)
A request for a SEP must include the
following minimal information:
i)
For a GWS, two quarterly samples.
01
L~2-0263
134
ii)
For a SWS or mixed system, four
quarterly samples.
C)
In issuing
a SEP, the Agency shall specify
the level of the contaminant upon which the
“reliably and consistently” determination was
based.
All SEPS that allow less frequent
monitoring based on an Agency “reliably and
consi~tently”determination shall include a
condition requiring the supplier to resume
quarterly monitoring pursuant to subsection
(k) (1)
above if it violates the MCL specified
by Section 611.311.
3)
Suppliers that monitor annually shall monitor
during the quarter(s)
that previously yielded the
highest analytical result.
4)
Suppliers that do not detect a contaminant at a
sampling point in three consecutive annual samples
may apply to the Agency for a SEP pursuant to
Section 611.110 that allows it to discontinue
monitoring for that contaminant at that point, as
specified in subsection
(g)
above.
5)
A GWS supplier that has detected one or more of
the two—carbon contaminants listed in subsection
(k) (5) (A) below shall monitor quarterly for vinyl
chloride as described in subsection
(k) (5) (B)
below, subject to the limitation of subsection
(k) (5) (C)
below.
A)
Two-carbon contaminants
(Phase I or II VOC):
1,2-Dichloroethane (Phase I)
1,1-Dichloroethylene
(Phase
I)
cis-l,2-Dichloroethylene
(Phase II)
trans-i,2-Dichloroethylene
(Phase II)
Tetrachloroethylene
(Phase II)
1,1,1-Trichloroethylene (Phase I)
Trichloroethylene
(Phase
I)
B)
The supplier shall sample quarterly for vinyl
chloride at each sampling point at which it
detected one or more of the two-carbon
contaminants listed in subsection
(k) (5) (A)
above.
C)
The Agency shall grant a SEP pursuant to
Section 611.110 that allows the supplier to
reduce the monitoring frequency for vinyl
chloride at any sampling point to once in
3
L:~2-i)26Lt
135
each three-year compliance period if it
determines that the supplier has not detected
vinyl chloride in first sample required by
subsection
(k) (5) (B)
above.
1)
Quarterly monitoring following MCL violations.
1)
Suppliers that violate an NCL for one of the Phase
I VOCs,
including vinyl chloride, or Phase II
VOCs, as determined by subsection
(0)
below,
shall
monitor quarterly for that contaminant, at the
sampling point where the violation occurred,
beginning the next quarter after the violation.
2)
Annual
monitoring.
A)
The Agency shall grant a SEP pursuant to
Section 611.110 that allows a supplier to
reduce the monitoring frequency to annually
if it determines that the sampling point is
reliably and consistently below the MCL.
B)
A request for a SEP must include the
following minimal information:
four
quarterly samples.
C)
In issuing a SEP, the Agency shall specify
the level of the contaminant upon which the
“reliably and consistently” determination was
based.
All SEPs that allow less frequent
monitoring based on an Agency “reliably and
consi~.tently”determination shall include a
condition requiring the supplier to resume
quarterly monitoring pursuant to subsection
(1) (1)
above if it violates the MCL specified
by Section 611.311.
D)
The supplier shall monitor during the
quarter(s) that previously yielded the
highest analytical result.
m)
Confirmation samples.
The Agency may issue a SEP
pursuant to Section 610.110 to require a supplier to
use a confirmation sample for results that it finds
dubious for whatever reason.
The Agency must state its
reasons for issuing the SEP if the SEP is Agency—
initiated.
1)
If a supplier detects any of the Phase
I VOCs or
Phase II VOCs in a sample, the supplier shall take
a confirmation sample as soon as possible, but no
later than 14 days after the supplier receives
01
~2-U265
136
notice of the detection.
2)
Averaging is as specified in subsection
(0)
below.
3)
The Agency shall delete the original or
confirmation sample if it determines that a
sampling error occurred,
in which case the
confirmation sample will replace the original or

o)
Compliance with the MCLs for the Phase
I VOCs and Phase
II VOC5 must be determined based on the analytical
results obtained at each sampling point.
1)
For suppliers that conduct monitoring at a
frequency greater than annual, compliance is
determined by a running annual average of all
samples taken at each sampling point.
A)
If the annual average of any sampling point
is greater than the MCL, then the supplier is
out of compliance.
B)
If the initial sample or a subsequent sample
would cause the annual average to exceed the
MCL, then the supplier is out of compliance
immediately.
C)
Any samples below the detection limit shall
be deemed as zero for purposes of determining
the annual average.
2)
If monitoring is conducted annually, or less
frequently, the supplier is out of compliance if
the level of a contaminant at any sampling point
is greater than the MCL.
If
a confirmation sample
is taken,
the determination of compliance is based
on the average of two samples.

Section 611.647
Sampling for Phase
I Volatile Organic
Contaminants
For systems in operation before January
1,
1993, for purposes of
initial monitoring, analysis of Phase I VOCs for purposes of
determining compliance with the MCL5 must be conducted as
follows:
a)
GWS suppliers shall sample at entry points
representative of each well after treatment.
Sampling
must be conducted at the same location(s)
or more
representative location(s)
every three months for one
year except as provided in subsection
(h) (1)
below.
b)
SWS and mixed system suppliers using surface sources
shall sample at points in the distribution system
representative of each source or at entry points to the
distribution system after any application of treatment.
SWS5 and mixed system suppliers shall sample each
source every three months except as provided in
subsection
(h) (2)
below.
Sampling must be conducted at
the same location or a more representative location
each quarter.
c)
If the system draws water from more than one source and
sources are combined before distribution, the supplier
shall sample at an entry point to the distribution
system during periods of normal operating conditions.
d)
Time for sampling.
1)
All CWS and NTNCWS suppliers serving more than
L~2-(J
269
140
3,300 people shall analyze all distribution or
entry—point samples, as appropriate,
representing
all source waters.
2)
All other CWS and NTNCWS suppliers shall analyze
distribution or entry—point samples, as required
in this paragraph,
representing all source waters
beginning no later than January
1,
1991.
e)
If the results exceed the NCL, the CWS or NTNCWS
supplier shall initiate three additional analyses at
the same sampling point within one month.
The sample
results must be averaged with the first sampling result
and used for compliance determination in accordance
with subsection
(i)
below.
The Agency shall delete
results of obvious sampling errors from this
calculation.
f)
Analysis for vinyl chloride is required only for GWSs
that have detected one or more of the following two—
carbon organic compounds: Trichloroethylene,
tetrachloroethylene,
l,2-dichloroethane,
1,1,1—
trichloroethane,
cis—l,2-dichloroethylene, trans—i,2—
dichloroethylene or 1,1-dichioroethylene.
The analysis
for vinyl chloride is required at each distribution or
entry point at which one or more of the two—carbon
organic compounds were found.
If the first analysis
does not detect vinyl chloride, the Agency shall reduce
the frequency of vinyl chloride monitoring to once
every three years for that sample location or other
sample locations that are more representative of the
same source.
g)
The Agency or suppliers may composite up to five
samples from one or more suppliers.
Compositing of
samples is to be done in the laboratory by the
procedures listed below.
Samples must be analyzed
within fourteen days of collection.
If any of the
Phase
I VOCs is detected in the original composite
sample,
a sample from each source that made up the
composite sample must be reanalyzed individually within
fourteen days from sampling.
The sample for reanalysis
cannot be the original sample but can be a duplicate
sample.
If duplicates of the original samples are not
available, new samples must be taken from each source
used in the original composite and analyzed for the
Phase
I
VOCs.
Reanalysis must be accomplished within
fourteen days of the second sample.
To composite
samples, the following procedure must be followed:
1)
Compositing samples prior to GC analysis.
0~
L~2-~J270

A)
Add
5 ml or equal larger amounts of each
sample
(up to 5 samples are allowed) to a 25
ml glass syringe.
Special precautions must
be made to maintain zero headspace in the
syringe.
B)
The samples must be cooled at
40
C during
this step to minimize volatilization losses.
C)
Mix well and draw out a 5-mi aliquot for
analysis.
D)
Follow sample introduction, purging and
desorption steps described in the method.
E)
If less than five samples are used for
compositing,
a proportionately smaller
syringe may be used.
2)
Compositing samples prior to GC/MS analysis.
A)
Inject 5—ml or equal larger amounts of each
aqueous sample
(up to
5 samples are allowed)
into a 25-mi purging device using the sample
introduction technique described in the
method.

Although USEPA has not repealed this provision,
the
Board has done so to avoid confusion.
This statement
maintains structural integrity with USEPA rules.
i)
Compliance with Section 611.311(a)
is determined based
on the results of running annual average of quarterly
sampling for each sampling location.
If one location’s
average is greater than the MCL, then the CWS or NTNCWS
is deemed to be out of compliance.
If a CWS or NTNCWS
has a distribution system separable from other parts of
the distribution system with no interconnections, only
that part of the system that exceeds any MCL as
specified in Section 611.311(a)
is deemed out of
compliance.
The Agency shall, by SEP, reduce the
public notice requirement to that portion of the CWS
that is out of compliance.
If any one sample result
would cause the annual average to be exceeded, then the
CWS is deemed to be out of compliance immediately.
For
CWS suppliers that only take one sample per location
because none of the Phase
I VOCs were detected,
compliance is based on that one sample.

k)
Compliance with the MCLs for the Phase II SOCs shall be
determined based on the analytical results obtained at
each sampling point.
1)
For suppliers that are conducting monitoring at a
frequency greater than annual, compliance is
determined by a running annual average of all
samples taken at each sampling point.
A)
If the annual average of any sampling point
is greater than the MCL, then the supplier is
out of compliance.
B)
If the initial sample or a subsequent sample
would cause the annual average to be
exceeded, then the supplier is out of
compliance immediately.
C)
Any samples below the detection limit must be
calculated as zero for purposes of
determining the annual average.
2)
If monitoring is conducted annually or less
frequently, the supplier is out of compliance if
the level of a contaminant at any sampling point
is greater than the MCL.
If a confirmation sample
is taken,
the determination of compliance is based
on the average of two samples.

0.2 parts per million
(ppm)
to protect against the risk
of these adverse health effects which have been
observed in laboratory -animals.
Drinking water which
meets this standard is associated with little to none
of this risk and should be considered safe.
9)
Fluoride.
The U.S. Environmental Protection Agency
requires that we send you this notice on the level of
fluoride in your drinking water.
The drinking water in
your community has a fluoride concentration of
milligrams per liter
(mgfL).
Federal regulations require that fluoride, which occurs
naturally in your water supply, not exceed a
concentration of 4.0 mg/L in drinking water.
This is
an enforceable standard called a Maximum Contaminant
Level
(MCL), and it has been established to protect the
public health.
Exposure to drinking water levels above
4.0 mg/L for many years may result in some cases of
crippling skeletal fluorosis,
which is a serious bone
disorder.
Federal law also requires that we notify you when
monitoring indicates that the fluoride in your drinking
water exceeds 2.0 mg/L.
This is intended to alert
families about dental problems that might affect
children under nine years of age.
The fluoride
concentration of your water exceeds this federal
guideline.
Fluoride in children’s drinking water at levels of
approximately
1 mg/L reduces the number of dental
cavities.
However, some children exposed to levels of
fluoride greater than about 2.0 mg/L may develop dental
fluorosis.
Dental fluorosis,
in its moderate and
severe forms,
is a brown staining and/or pitting of the
permanent teeth.
Because dental fluorosis occurs only when developing
teeth (before they erupt from the gums)
are exposed to
elevated fluoride levels, households without children
are not expected to be affected by this level of
fluoride.
Families with children under the age of nine
are encouraged to seek other sources of drinking water
~flL~2-02E-
8
159
for their children to avoid the possibility of staining
and pitting.
Your water supplier can lower the concentration of
fluoride in your water so that you will still receive
the benefits of cavity prevention while the possibility
of stained and pitted teeth is minimized.
Removal of
fluoride may increase your water costs.
Treatment
systems are also commercially available for home use.
Information on such systems is available at the address
given below.
Low fluoride bottled drinking water that
would meet all standards is also commercially
available.
For further information, contact
at your
water system.

10)
Microbiological contaminants
(for use when there is a
violation of the treatment technique requirements for
filtration and disinfection in Subpart B of this Part).
The United States Environmental Protection Agency
(USEPA)
sets drinking water standards and has
determined that the presence of microbiological
contaminants are a health concern at certain levels of
exposure.
If water is inadequately treated,
microbiological contaminants in that water may cause
disease.
Disease symptoms may include diarrhea,
cramps, nausea and possibly jaundice and any associated
headaches and fatigue.
These symptoms, however, are
not just associated with disease—causing organisms in
drinking water,
but also may be caused by a number of
factors other than your drinking water.
USEPA has set
enforceable requirements for treating drinking water to
reduce the risk of these adverse health effects.
Treatment such as filtering and disinfecting the water
removes or destroys microbiological contaminants.
Drinking water which is treated to meet USEPA
requirements is associated with little to none of this
risk and should be considered safe.
11)
Total coliforms.
(To be used when there is a violation
of Section 611.325(a)
and not a violation of Section
611.325(b)).
The United States Environmental
Protection Agency
(USEPA)
sets drinking water standards
and has determined that the presence of total coliforms
is a possible health concern.
Total coliforms are
common in the environment and are generally not harmful
themselves.
The presence of these bacteria in drinking
water, however, generally is
a result of
a problem with
O~L~.2-O269
160
water treatment or the pipes which distribute the water
and indicates that the water may be contaminated with
organisms that can cause disease.
Disease symptoms may
include diarrhea, cramps, nausea and possibly jaundice,
and any associated headaches and fatigue.
These
symptoms, however, are not just associated with
disease—causing organisms in drinking water, but also
may be caused by a number of factors other than your
drinking water.
USEPA has set an enforceable drinking
water standard for total coliforms to reduce the risk
of these adverse health effects.
Under this standard,
no more than 5.0 percent of the samples collected
during a month can contain these bacteria, except that
systems collecting fewer than 40 samples/month that
have one total coliform—positive sample per month are
not violating the standard.
Drinking water which meets
this standard is usually not associated with a health
risk from disease—causing bacteria and should be
considered safe.
12)
Fecal Coliforms/E.
coli.
(To be used when there is a
violation of Section 611.325(b)
or both Section
611.325(a)
and
(b)).
The United States Environmental
Protection Agency
(USEPA) sets drinking water standards
and has determined that the presence of fecal coliforms
or E. coli is a serious health concern.
Fecal
coliforms and E. coil are generally not harmful
themselves, but their presence in drinking water is
serious because they usually-are associated with sewage
or animal wastes.
The presence of these bacteria in
drinking water is generally a result of a problem with
water treatment or the pipes which distribute the water
and indicates that the water may be contaminated with
organisms that can cause disease.
Disease symptoms may
include diarrhea, cramps, nausea and possibly jaundice,
and associated headaches and fatigue.
These symptoms,
however,
are not just associated with disease—causing
organisms in drinking water, but also may be caused by
a number of factors other than your drinking water.
USEPA has set an enforceable drinking water standard
for fecal coliforins and E. coil to reduce the risk of
these adverse health effects.
Under this standard all
drinking water samples must be free of these bacteria.
Drinking water which meets this standard is associated
with little or none of this risk and should be
considered safe.
State and local health authorities
recommend that consumers take the following
precautions:

consistency with UCEPA rules.Lead.
The United States
Environmental Protection Agency
(USEPA)
sets drinking
water standards and has determined that lead is
a
health concern at certain exposure levels.
Materials
that contain lead have freciuently been used in the
construction
of
water
supply
distribution
systems.
and
plumbing systems in private homes and other buildings.
The_most commonly found materials include service
lines, pipes.
brass and bronze fixtures, and solders
and fluxes.
Lead in these materials can contaminate
drinking water as a result of the corrosion that takes
place when water comes into contact with those
materials.
Lead can cause a variety of adverse health
effects in humans.
At relatively low levels of
exPosure,
these effects may include interference with
red blood cell chemistry,
delays in normal physical and
mental development in babies and young children, slight
deficits in the attention span. hearing,
and learning
abilities of children, and slight increases in the
blood pressure of some adults.
USEPA’s national
irimarv drinking water regulation requires all public
water systems to optimize corrosion control to minimize
lead contamination resulting from the corrosion of
plumbing materials.
Public water systems serving
50~000people or fewer that have lead concentrations
below 15 parts per billion (p~b) in more than 90
of
taP water samples (the USEPA “action level”) have
optimized their corrosion control treatment.
Any water
system that exceeds the action level must also monitor
their source water to determine whether treatment to
remove lead in source water is needed.
Any water
system that continues to exceed the action level after
installation of corrosion control and/or source water
treatment must eventually re~1aceall lead service
lines contributing in excess of 15 p~bof lead to
drinking water.
AnY water system that exceeds the
action level must also undertake a public education
program to inform consumers of ways they can reduce
their exposure to potentially high levels of lead in
drinking water.

consistency with UCEPA rules.Cppper.
The United States
Environmental Protection Agency
(USEPA) sets drinking
water standards and has determined that comper is a
health concern at certain exposure levels.
CoPter.
a
reddish-brown metal,
is often used to plumb residential
and commercial structures that are connected to water
distribution systems.
Copper contaminating drinking
water as a corrosion by—product occurs as the result of
3jI~.2-029I
162
the corrosion of copper pipes that remain in contact
with water for a ~rolon~ed period of time.
Co~~eris
an essential nutrient, but at high doses it has been
shown to cause stomach and intestinal distress, liver
and kidney damage, and anemia.
Persons with Wilson’s
disease may be at a higher risk of health effects due
to copper than the general public.
USEPA’s national
primary drinking water regulation requires all public
water systems to install optimal corrosion control to
minimize copper contamination resulting from the
corrosion of olumbing materials.
Public water systems
serving 50,000 people or fewer that have copper
concentrations below 1.3 parts per million (~~m)in
more than 90
of tap water samples
(the USEPA “action
level”)
are not required to install or improve their
treatment.
Any water system that exceeds the action
level must also monitor their source water to determine
whether treatment to remove copper in source water is
needed.
15)
Asbestos.
The United States Environmental Protection
Agency
(USEPA) sets drinking water standards and has
determined that asbestos fibers greater than
10 micrometers in length are a health concern at
certain levels of exposure.
Asbestos is a naturally
occurring mineral.
Most asbestos fibers in drinking
water are less than 10 micrometers in length and occur
in drinking water from natural sources and from
corroded asbestos—cement pipes in the distribution
system.
The major uses of asbestos were in the
production of cements, floor tiles, paper products,
paint, and caulking; in transportation-related
applications; and in the production of textiles and
plastics.
-
Asbestos was once a popular insulating and
fire retardant material.
Inhalation studies have shown
that various forms of asbestos have produced lung
tumors in laboratory animals.
The available
information on the risk of developing gastrointestinal
tract cancer associated with the ingestion of asbestos
from drinking water is limited.
Ingestion of
intermediate—range chrysolite asbestos fibers greater
than 10 micrometers in length is associated with
causing benign tumors in male rats.
Chemicals that
cause cancer in laboratory animals also may increase
the risk of cancer in humans who are exposed over long
periods of time.
USEPA has set the drinking water
standard for asbestos at 7 million long fibers per
liter to reduce the potential risk of cancer or other
adverse health effects which have been observed in
laboratory animals.
Drinking water which meets the
USEPA standard is associated with little
to- none of
this risk and should be considered safe with respect to

Mandatory Lead Public Education
Information
fl.
INTRODUCTION
The United States Environmental Protection Agency
(EPA) and
linsert name of water sup~lier1are concerned about lead in your
drinking water.
Although most homes have very low levels of lead
in their drinking water. some homes in the community have lead
levels above the EPA action level of 15 carts ~er billion (~pb).
;,
~~--~c-~
179
or 0.015 milligrams of lead per liter of water (mg/L).
Under
Federal law we are required to have a program in place to
minimize lead in your drinking water by
linsert date when
corrosion, control will be completed for your system1~. This
program includes corrosion control treatment,
source water
treatment,
and public education.
We are also required to replace
each lead service line that we control if the line contributes
lead concentrations of more than 15 ppb after we have completed
the comprehensive treatment program.
If you have any questions
about how we are carrying out the requirements of the lead
regulation please give us a call at insert
water system’s phone
numberl.
This brochure explains the simple steps you can take to
protect you and your family by reducing your exposure to lead in
drinking water.
~j.
HEALTH EFFECTS OF LEAD
Lead is a common metal found throuahout the environment in lead—
based paint,
air,- soil, household dust,
food,
certain types of
pottery porcelain and pewter, and water.
Lead can pose a
significant risk to your health if too much of it enters your
body.
Lead builds up in the body over many years and can- cause
damage to the brain,
red blood cells and kidneys.
The greatest
risk is to young children and pregnant women.
Amounts of lead
that won’t hurt adults can slow down normal mental and physical
development of growing bodies.
In addition,
a child at play
often comes into contact with sources of lead contamination
——
like dirt and dust
--
that rarely affect an adult.
It is
important to wash children’s hands and toys often,
and to try to
make sure they only put food in their mouths.
fl
LEAD IN DRINKING WATER
~j.
Lead in drinking water, although rarely the sole cause
of lead poisoning, can significantly increase a
person’s total lead exposure, ~articularlv the exposure
of infants who drink baby formulas and concentrated
luices that are mixed with water.
The EPA estimates
that drinking water can make up 20 percent or more of a
person’s total exposure to lead.
~j.
Lead is unusual amona drinking water contaminants in
that it seldom occurs naturally in water supplies like
rivers and lakes.
Lead enters drinking water primarily
as
a result of the corrosion,
or wearing away..
of
materials containing lead in the water distribution
system and household plumbing.
These materials include
lead—based solder used to loin copper pipe, brass and
chrome plated brass faucets, and in some cases, pipes
made of lead that connect your house to the water main
(service lines).
In 1986. Congress banned the use of
lead solder containing greater than 0.2
lead, and
0 R2-0309
180
restricted the lead content of faucets, pipes and other
plumbing materials to 8.0.
QJ.
When water stands in lead pipes or plumbing systems
containing lead for several hours or more, the lead may
dissolve into your drinking water.
This means the first
water drawn from the tap in the morning, or later in
the afternoon after returning from work or school,
can
contain fairly high levels of lead.
j)
STEPS YOU CAN
TAKE
IN THE HOME TO REDUCE EXPOSURE TO LEAD IN
DRINKING WATER
~j
Despite our best efforts mentioned earlier to control
water corrosivity and remove lead from the water
supply.
lead levels
in some homes or buildings can be
high.
To find out whether you need to take action in
your own home,
have your drinking water tested to
determine if it contains excessive concentrations of
lead.
Testing the water is essential because you
cannot see, taste, or smell lead in drinking water.
Some local laboratories that can provide this service
are listed at the end of this booklet.
For more
information on having your water tested, please call
insert
phone number of water systemi.
~
If a water test indicates that the drinking water drawn
from
a tap in your home contains lead above 15 ppb,
then you should take the following precautions:
fl
Let the water run from the tap before using it for
drinking or cooking any time the water in a faucet
has gone unused for more than six hours.
The
1on~erwater resides in your home’s plumbing the
more lead it may contain.
Flushing the tap means
running the cold water faucet until the water gets
noticeably colder, usually about 15—30 seconds.
If your house has a lead service line to the water
main, you may have to flush the water for a longer
time, perhaps one minute. before drinking.
Although toilet flushing or showering flushes
water through a portion of your home’s plumbing
system. you still need to flush the water in each
faucet before using it for drinking or cooking.
Flushing tap water is a simple and inexpensive
measure you can take to protect your family’s
health.
It usually uses less than one or two
~ailons of water and costs less than
Iinsert a
cost estimate based on flushing two times a day
for 30 days
per month.
To conserve water, fill
a
couple of bottles for drinking water after
flushing the tap,
and whenever possible use the
0
~~2-O3
I
0
181
first flush water to wash the dishes or water the
plants.
If you live in a high-rise building,
letting the water flow before using it may not
work to lessen your risk from lead.
The plumbing
systems have more,
and ‘sometimes larger pipes than
smaller buildings.
Ask your landlord for help in
locating the source of the lead and for advice on
reducing the lead level.
jJJ..
Try not to cook with,
or drink water from the hot
water tap.
Hot water can dissolve more lead more
quickly than cold water.
If you need hot water,
draw water from the cold ta~and heat it on the
stove.
iii) Remove loose lead solder and debris from the
plumbing materials installed in newly constructed
homes,
or homes
in which the plumbing has recently
been replaced~by removing the faucet strainers
from all taps and running the water from 3 to 5
minutes.
Thereafter, periodically remove the
strainers and flush out any debris that has
accumulated over time.
i~1
If your copper pipes are loined with lead solder
that has been installed illegally since it was
banned in 1986, notify the plumber who did the
work and request that he or she replace the lead
solder with lead—free solder.
Lead solder looks
dull gray.
and when scratched with a key looks
shiny.
In addition, notify your State (insert
name of department responsible for enforcing the
Safe Drinking Water Act in your Statel about the
violation.
yI
Determine whether or not the service line that
connects your home or apartment to the water main
is_made_of lead.
The best way to determine if
your service line is made of lead is by either
hiring a licensed plumber to inspect the line or
by contacting the plumbing contractor who
installed the line.
You can identify the plumbing
contractor by checking the city’s record of
building permits which should be maintained in the
files of the
insert
name of department that
issues building permits).
A licensed plumber can
at the same time check to see if your homes’s
plumbing contains lead solder,
lead pipes,
or pipe
fittings that contain lead.
The public water
system that delivers water to your home should
also maintain records of the materials located in
the distribution system.
If the service line that
0t14-2-031
I
182
connects your dwelling to the water main
contributes more than 15 ppb to drinking water,
after our- comprehensive treatment pro~am is in
place. we are required to replace the line.
If
the line
is only partially controlled by the
insert
name of
the
city, county, or water system
that controls the line,
we are required to
provide you with information on how to replace
your portion of the service line,
and offer to
replace that portion of the line at your expense
and take a follow-up tap water sample within 14
days of the replacement.
Acceptable replacement
alternatives include copper.
steel,
iron,
and
plastic pipes.
y11
Have an electrician check your wiring.
If
grounding wires from the electrical system are
attached to your pipes, corrosion may be greater.
Check with a licensed electrician or your local
electrical code to determine if your wiring can be
grounded elsewhere.
DO NOT attempt to change the
wiring yourself because improper grounding can
cause electrical shock and fire hazards.
çj
The steps described above will reduce the lead
concentrations in your drinking water.
However,
if a
water test indicates that the drinking water coming
from your ta~contains lead concentrations in excess of
15 p~bafter flushing, or after we have completed our
actions to minimize lead levels, then you maY want to
take the following additional measures:
j).
Purchase or lease a home treatment device.
Home
treatment devices are limited in that each unit
treats only the water that flows from the faucet
to which it is connected, and all of the devices
require periodic maintenance and replacement.
Devices such as reverse osmosis systems or
distillers can effectively remove lead from your
drinking water.
Some activated carbon filters may
reduce_lead levels at the tap, however all lead
reduction- claims should be investigated.
Be sure
to check the actual performance of a specific home
treatment device before and after installing the
unit.
jJJ..
Purchase bottled water for drinking and cooking.
Q1
You can consult a variety of sources for additional
information.
Your family doctor or pediatrician can
perform a blood test for lead and provide you with
information about the health effects of lead.
