Proposal for Public Comment.
Proposed 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 that
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 M.
Gunn, Clerk of the Illinois Pollution Control
Board, do hereby certify that the above order was adopted by the

Section 611.110
Special Exception Permits
a)
Unless otherwise specified,
each Agency determination
in this Part is to be made by way of a written permit
pursuant to Section 39(a)
of the Act.
Such permit is
titled a “special exception” permit
(“SEP”).
b)
No person shall cause or allow the violation of any
condition of a SEP.
c)
The supplier may appeal the denial of or the conditions
of a SEP to the Board pursuant to Section 40 of the
Act.
d)
A SEP may be initiated either:
1)
By an application filed by the supplier; or
0~L~2-U385
44
2)
By the Agency, when authorized by Board
regulations.
BOARD NOTE:
The Board does not intend to mandate
by any provision of this Part that the Agency
exercise its discretion and initiate a SEP
pursuant to subsection
(d) (2)
above.
Rather, the
Board intends to clarify by this subsection that
the Agency may opt to initiate a SEP without
receiving
a request from the supplier.
e)
The Agency shall evaluate a request for a SEP from the
monitoring requirements of Section 611.646(e) and
(f)
(Phase I.
Phase II, and Phase V VOCs and Phacic II
VOCo),
Section 611.646(d), only as to initial
monitoring for 1.2 ,4—trichlorobenzerie, Section
611.648(a)
(for Phase II, Phase IIB. and Phase V SOCs)
andor Section 611.510(a)
(for unregulated organic
contaminants) on the basis of knowledge of previous use
(including transport, storage, or disposal)
of the
contaminant in the watershed or zone of influence of
the system, as determined pursuant to 35 Ill. Adm. Code
671:
1)
If the Agency determines that there was no prior
use of the contaminant,
it shall grant the SEP,
or
2)
If the contaminant was previously used or the
previous use was unknown, the Agency shall
consider the following factors:
A)
Previous analytical results;
B)
The proximity of the system to any possible
point source of contamination (including
spills or leaks at or near a water treatment
facility; at manufacturing, distribution, or
storage facilities; from hazardous and
municipal waste land fills;
or from waste
handling or treatment facilities) or non-
point source of contamination (including the
use of pesticides and other land application
uses of the contaminant);
C)
The environmental persistence and transport
of the contaminant;
D)
How well the water source is protected
against contamination,
including whether it
is
a SWS or a GWS:
i)
A GWS must consider well depth,
soil
~.
45
type,
and well casing integrity, and
ii)
A
SWS
must consider watershed
protection; and
E)
For Phase II, Phase
IIB. and Phase V SOC5 and
unregulated organic contaminants
(pursuant to
Section
611.631
or
611.648)
i)
Elevated nitrate levels at the water
source;
and
ii)
The use of PCB5 in equipment used in the
production,
storage, or distribution of
water
(including pumps,
transformers,
etc.); and
F)
For Phase I.
Phase II, and Phase V VOC5 and
Phacic II VOCs (pursuant to Section 611.646):
the number of persons served by the PWS and
the proximity of a smaller system to a larger
one.
f)
If a supplier refuses to provide any necessary
additional information requested by the Agency,
or if a
supplier delivers any necessary information late in the
Agency’s deliberations on a request, the Agency may
deny the requested SEP or grant the SEP with conditions
within the time allowed by law.

Section 611.130
Special Requirements for Certain Variances
and Adjusted Standards
a)
Relief from the
TTHM
MCL.
46
1)
In granting any variance or adjusted standard to a
supplier
that
is
a
CWS
that
adds
a
disinfectant
at
any
part
of
treatment
and
which
provides
water
to
10,000 or more persons on a regular basis from the
maximum
contaminant
level
for
TTHM
listed
in
Section 611.310(c), the Board will require
application of the best available technology
(BAT)
identified at subsection
(a) (4) below for that
constituent as
a condition to the relief, unless
the supplier has demonstrated through
comprehensive
engineering
assessments
that
application of BAT is not technically appropriate
and technically feasible for that system, or it
would only result in a marginal reduction in
TTHN
for that supplier.
2)
The
Board
will
require
the
following
as
a
condition for relief from the
TTHN
MCL where it
does not require the application of BAT:
A)
That the supplier continue to investigate the
following methods as an alternative means of
significantly reducing the level of
TTHM,
according to a definite schedule:
i)
introduction
of
off-line
water
storage
for
THM
precursor
reduction;
ii)
aeration for
TTHM
reduction,
where
geography
and
climate
allow;
iii)
introduction of clarification, where not
presently practiced;
iv)
use of alternative sources of raw water;
and
v)
use of ozone as an alternative or
supplemental disinfectant or oxidant,
and
B)
That the supplier report results of that
investigation to the Agency.
3)
The Agency shall petition the Board to reconsider
or modify a variance or adjusted standard,
pursuant to 35 Ill. Adm. Code 101.Subpart
K,
if
it
determines that an alternative method identified
by the supplier pursuant to subsection
(a) (2)
above is technically feasible and would result in
a significant reduction in TTKM.

Best available technology for TTHM reduction:
A)
use of chloramines as an alternative or
supplemental disinfectant,
B)
use of chlorine dioxide as an alternative or
supplemental disinfectant, or
C)
improved existing clarification for
THM
precursor reduction.
BOARD
NOTE:
Derived from 40 CFR 142.60
(1992).
The restrictions of this subsection
do not apply to suppliers regulated for
TTHM
as an additional state requirement.
See the
Board Note to Section 611.301(c).
b)
Relief from the fluoride MCL.
1)
In granting any variance or adjusted standard to a
supplier that is a CWS from the maximum

611.301(b),
the Board will require application of
the best available technology
(BAT)
identified at
subsection
(b) (4) below for that constituent as a
condition to the relief, unless the supplier has
demonstrated through comprehensive engineering
assessments that application of BAT is not
technically appropriate and technically feasible
for that supplier.
2)
The Board will require the following as a
condition for relief from the fluoride MCL where
it does not require the application of BAT:
A)
That the supplier continue to investigate the
following methods as an alternative means of
significantly reducing the level of
TTHM,
according to a definite schedule:
i)
modification of lime softening;
ii)
alum coagulation;
iii) electrodialysis;
iv)
anion exchange resins;
v)
well field management;
vi)
use of alternative sources of raw water;
and

vii) regionalization, and
B)
That the supplier report results of that
investigation to the Agency.
3)
The Agency shall petition the Board to reconsider
or modify a variance or adjusted standard,
pursuant to 35 Ill.
Athu.
Code 101.Subpart K,
if it
determines that an alternative method identified
by the supplier pursuant to subsection
(b) (2)
above
is technically feasible and would result in
a significant reduction in fluoride.
4)
Best available technology for fluoride reduction:
A)
activated alumina absorption centrally
applied, and
B)
reverse osmosis centrally applied.
BOARD NOTE:
Derived from 40 CFR 142.61
(1992)
c)
Relief from an inorganic chemical contaminant, VOC, or
SOC MCL.
1)
In granting to a supplier that is a CWS or NTNCWS
any variance or adjusted standard from the maximum
contaminant levels for any VOC or SOC,
listed in
Section 611.311(a)
or
(c), or for any inorganic
chemical contaminant, listed in Section 611.301,
the supplier must have first applied the best
available technology
(BAT)
identified at Section
611.311(b)
(VOC5 and SOCs)
or Section 611.301(c)
(inorganic chemical contaminants) for that
constituent, unless the supplier has demonstrated
through comprehensive engineering assessments that
application of BAT would achieve only a minimal
and insignificant reduction in the level of
contaminant.
BOARD NOTE:

at 40 CFR 142.62(p)
(1992). as amended at 57 Fed.
Req.

the section
142.62 listing adds PTA (“PAT”)
for alachior;
lists OX for hexachlorobenzene,
instead of GAC;
and omits PTA for toxaphene.
The Board has chosen
to use the section 141.61(a)

(although the preamble at 56 Fed. Reg. 3529
(Jan.

indicates that it is
wrong
as to
toxaphene).
2)
The Board may require any of the following as a
condition for relief from a MCL listed in Section
611.301 or 611.311:
A)
That the supplier continue to investigate
alternative means of compliance according to
a definite schedule, and
B)
That the supplier report results of that
investigation to the Agency.
3)
The Agency shall petition the Board to reconsider
or modify a variance or adjusted standard,
pursuant to 35 Ill. Adm. Code l0l.Subpart K,
if
it

BOARD
NOTE:
Derived from 40 CFR 142.62(a) through
(e)
(1992).
d)
Conditions requiring use of bottled water or point-of-
use or point—of—entry devices.
In granting any
variance or adjusted standard from the maximum
contaminant levels for organic and inorganic chemicals
or an adjusted standard from the treatment technique
for lead and copper, the Board may impose certain
conditions requiring the use of bottled water, point-
of-entry devices, or point—of-use devices to avoid an
unreasonable risk to health, limited as provided in
subsections
(e) and
(f)
below.
1)
Relief from an MCL.
The Board may, when granting
any variance or adjusted standard from the MCL
requirements of Sections 611.301 and 611.311,
impose a condition that requires a supplier to use
bottled water, point-of—use devices, point—of-
entry devices or other means to avoid an
unreasonable risk to health.
2)
Relief from corrosion control treatment.
The
Board may, when granting an adjusted standard from
the corrosion control treatment requirements for
lead and copper of Sections 611.351 and 611.352,
impose a condition that requires a supplier to use
01
L~.2-039
I
50
bottled water and point—of—use devices or other
means,
but not point—of—entry devices, to avoid an
unreasonable risk to health.
3)
Relief from source water treatment or service line
replacement.
The Board may, when granting an
exemption from the source water treatment and lead
service line replacement requirements for lead and
copper under Sections 611.353 or 611.354, impose a
condition that requires a supplier to use point—
of—entry devices to avoid an unreasonable risk to
health.
BOARD
NOTE:
Derived from 40 CFR 142.62(f)
(1992).
e)
Use of bottled water.
Suppliers that propose to use or
use bottled water as a condition for receiving a
variance or an adjusted standard from the requirements
of Section 611.301 or Section 611.311, or an adjusted
standard from the requirements of Sections 611.351
through 611.354 must meet the requirements of either
subsections
(e)(l),
(e)(2),
(e)(3),
and (e)(6)
or
(e) (4),
(e) (5) and
(e) (6)
below:
1)
The supplier must develop a monitoring program for
Board approval that provides reasonable assurances
that the bottled water meets all MCLs of Sections
611.301 and 611.311 and submit
a description of
this program as part of its petition.
The
proposed program must describe how the supplier
will comply with each requirement of this
subsection.
2)
The supplier must monitor representative samples
of the bottled water for all contaminants
regulated under Sections 611.301 and 611.311
during the first three-month period that it
supplies the bottled water to the public, and
annually thereafter.
3)
The supplier shall annually provide the results of
the monitoring program to the Agency.
4)
The supplier must receive a certification from the
bottled water company as to each of the following:
A)
that the bottled water supplied has been
taken from an approved source of bottled
water,
as such is defined in Section 611.101;
B)
that the approved source of bottled water has
conducted monitoring
in accordance with 21
0
L~.2-U392
51
CFR 129. 80(g) (1) through (3);
C)
and that the bottled water does not exceed
any MCL5 or quality limits as set out in 21
CFR 103.35,
110, and 129.
5)
The supplier shall provide the certification
required by subsection
(e) (4) above to the Agency
during the first quarter after it begins supplying
bottled water and annually thereafter.
6)
The supplier shall assure the provision of
sufficient quantities of bottled water to every
affected person supplied by the supplier via door-
to-door bottled water delivery.
Derived from 40 CFR 142.62(g)
(1992).
f)
Use of point—of-entry devices.
Before the Board grants
any PWS a variance or adjusted standard from any
NPDWR
that includes a condition requiring the use of
a point-
of-entry device, the supplier must demonstrate to the
Board each of the following:
1)
that the supplier will operate and maintain the
device;
2)
that the device provides health protection
equivalent to that provided by central treatment;
3)
that the supplier will maintain the
microbiological safety of the water at all times;
4)
that the supplier has established standards for
performance, conducted a rigorous engineering
design review, and field tested the device;
5)
that the operation and maintenance of the device
will account for any potential for increased
concentrations of heterotrophic bacteria resulting
through the use of activated carbon, by
backwashing, post-contactor disinfection, and
heterotrophic plate count monitoring;
6)
that buildings connected to the supplier’s
distribution system have sufficient devices
properly installed, maintained, and monitored to
assure that all consumers are protected; and
7)
that the use of the device will not cause
increased corrosion of lead and copper bearing
materials located between the device and the tap
UH4~Ui
52
that could increase contaminant levels at the tap.

NOTE:
Derived from 40 CFR 141.11(b)

(c)
(1992).
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 MCL5 at 40 CFR 141.62
at 56 Fed.
Reg. 3594
(Jan.
30,
1991).
Following
the changing USEPA codification scheme creates two
listings of NCL5:
one at this Section and one at
Section 611.301.
This causes fluoride to appear
in both the 40 CFR 141.11(b) and 141.62(b)
listings with the same MCL.
The Board has deleted
the corresponding fluoride MCL from this Section
in favor of that which appears at Section
611.301(b).
USEPA adopted a MCL for cyanide at 40

Standard for SEP reduction in monitoring.
The Agency
shall grant a SEP that allows a reduction in the
monitoring frequency if the supplier demonstrates that
all previous analytical results were less than the MeL,
provided the supplier meets the following minimum data
requirements:
1)
For GWS suppliers:
a minimum of three rounds of
monitoring.
2)
For SWS and mixed system suppliers:
annual
monitoring for at least three years.

Standard for SEP monitoring conditions.
As a condition
of any SEP, the Agency shall require that the supplier
take a minimum of one sample during the term of the
SEP.
In determining the appropriate reduced monitoring
frequency,
the Agency shall consider:
1)
Reported concentrations from all previous
monitoring;
2)
The degree of variation in reported
concentrations; and
3)
Other factors may affect contaminant

1)
If the average at any sampling point is greater
than the MCL, then the supplier is out of
compliance.
2)
If any one sample would cause the annual average
to be exceeded, then the supplier is out of
compliance immediately.
3)
Any sample below the method detection limit must
be calculated at zero for the purpose of
determining the annual average.
BOARD NOTE:
The “method detection limit” is
different from the “detection limit”, as set forth
in Section 611.600.
The “method detection limit”
is the level of contaminant that can be determined
by a particular method with a 95 percent degree of
confidence,
as determined by the method outlined
in 40 CFR 136,
appendix’B,
incorporated by
reference at Section 611.102.
b)
For suppliers that monitor annually or less frequently,
compliance with the MCLs for antimony. asbestos,
barium, beryllium,
cadmium, chromium, cyanide,
fluoride, mercury, e~i4nickel. selenium, and thallium is
determined by the level of the contaminant at any
sampling point.
If a confirmation sample is taken, the
determination of compliance will be based on the
average of the two samples.
c)
Compliance with the NCLs for nitrate and nitrite is
determined based on one sample if the levels of these
contaminants are below the MCL5.
If the levels of
nitrate or nitrite exceed the MCLs in the initial
sample, Section 611.606 requires confirmation sampling,
and compliance is determined based on the average of
U
t4~.ti4
74
the initial and confirmation samples.
d)
When the portion of the distribution system that is out
of compliance is separable from other parts of the
distribution system and has no interconnections, the
supplier may give the public notice required by Subpart
T
only to persons served by that portion of the
distribution system not in compliance.

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)
(1992).
This is
a “trigger level”
for Phase
I, Phase II.
and Phase
y
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
(1
~2-OL~.37
96
determined from analysis of a sample in a given
matrix containing the analyte.
BOARD NOTE:
Derived from 40 CFR 136, Appendix B
(1992).
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 GWS5.
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 SWS5 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) (I) through
(f)(3)
(1992).
d)
Each CWS and NTNCWS supplier shall take four
consecutive quarterly samples for each of the Phase I
VOC5,
excluding vinyl chloride,
and Phase II VOCs
during each compliance period, beginning in the
compliance period starting January
1,
1993in the
initial compliance period.

e)
Reduction to annual monitoring frequency.
If the
initial monitoring for the Phase
I. Phase II, and Phase
V VOCs and Phase II VOCs as allowed in subsection
(r) (1) below has been completed by December 31,
1992,
and the supplier did not detect any of the Phase
I
VOCs,
including vinyl chloride, e~—PhaseII, or Phase V
VOC5, then the supplier shall take one sample annually
beginning January
1,
1993in the initial compliance
period.
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, e~’—PhaseII. or
Phase V
VOC5 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. and Phase V
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.
A supplier that serves
fewer than 500 service connections may apply to the
Agency for a SEP pursuant to Section 611.110 that
releases it from the requirements of subsection
(d)
above as to 1,2,4—trichlorobenzene.
BOARD NOTE:
Derived from 40 CFR 141.24(f) (7) and
(f) (10)
(1992),
as amended at 57 Fed. Req. 31841
(July
17,
1992). and the discussion at 57 Fed. Req. 31825
(July 17,
1992).
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
(d).
(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, except that a SEP as to
the subsection
(d)
above monitoring for 1,2.4-tn—
chlorobenzene
shall
apply
only
to
the
initial
round
of
monitoring.
As a condition of
a SEP, except as to a
SEP
from the initial round of subsection
(d) above
monitoring for 1.2,4-trichlorobenzene. the supplier
shall, within 30 months after the beginning of the
period for which the waiver was issued, reconfirm its
0! ~2-0L~.39
98
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 SWS5
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, Phase II,
and Phase V 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 GWS5,
and 40 CFR 141.24(f) (10), the
provision for SWS5.
The Board has consolidated
the common requirements of both paragraphs into
subsection
(g)
above.
Subsection
(j)
above
represents the elements unique to SWS5 and mixed
systems, and subsection
(i)
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,
er—Phase II, or Phase V VOC5 is detected in any sample,
then:
1)
The supplier shall monitor quarterly for that
L.
7
—
ii
i4
fJ
99
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 MCL.
B)
A request for a SEP must include the
following minimal information:
i)
For a GWS, two quarterly samples.
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
consistently”
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

purposes of determining compliance with the MCL must be conducted
as follows:
a)
Definitions.
As used in this Section:
01
~
105
“Detect or detection” means that the contaminant
of interest is present at a level greater than or
equal to the “detection limit”.
“Detection limit” means the level of the
contaminant of interest that is specified in
subsection
(r)
below.
BOARD
NOTE:
This is a “trigger level” for Phase
II, Phase
IIB, and Phase V SOC5 inasmuch as it
prompts further action.
The use of the term
“detect” or “detection” in this section is not
intended to include any analytical capability of
quantifying lower levels of any contaminant, or
the “method detection limit”.
b)
Required sampling.
Each supplier shall take a minimum
of one sample at each sampling point at the times
required in subsection
(q)
below.
BOARD NOTE:
USEPA stayed the effective date of the
MCLs for aldicarb, aldicarb sulfone, and aldicarb
sulfoxide at 57 Fed.
Reg. 22178
(May 27,
1991).
Section 611.311(c)
includes this stay.
However,
despite the stay of the effectiveness of the MCL5 for
these three SOCs,
suppliers must monitor for them.
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,
01 L~.2-Qt~.L~.7
106
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(h) (1) through

compliance period, beginning in the three—year
compliance period starting January
1,
1993in the
initial compliance period.
2)
Suppliers serving more than 3,300 persons that do
not detect a contaminant in the initial compliance
period,
shall take a minimum of two quarterly
samples
in one year of each subsequent three—year
compliance period.
3)
Suppliers serving less than or equal to 3,300
persons that do not detect a contaminant in the
initial compliance period, shall take a minimum of
one sample during each subsequent three—year
compliance period.
e)
Reduction to annual monitoring frequency.
A CWS or
NTNCWS supplier may apply to the Agency for a SEP that
releases it from the requirements of subsection
(d)
above.
A SEP from the requirement of subsection
(d)
above shall last for only a single three—year
compliance period.
f)
Vulnerability Assessment.
The Agency shall grant a SEP
from the requirements of subsection
(d)
above based on
consideration of the factors set forth at Section
611.110(e).
g)
If one of the Phase II,
Phase IIB. or Phase V SOCs is
detected
in. any sample, then:
1)
The supplier shall monitor quarterly for the
contaminant at each sampling point that resulted
in a detection.
2)
Annual
monitoring.
A)
A
supplier
may
request
that
the
Agency
grant
a SEP pursuant to Section 610.110 that

3)
Suppliers that monitor annually shall monitor
during the quarter(s) that previously yielded the
highest analytical result.
4)
Suppliers that have three consecutive annual
samples with no detection of a contaminant at a
sampling point may apply to the Agency for a SEP
with respect to that point,
as specified in
subsections
(e) and
(f)
above.
5)
Monitoring for related contaminants.
A)
If monitoring results in detection of one or
more of the related contaminants listed in
subsection
(g)
(5)

drinking water standard for 1,1,1-trichloroethane at
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
119
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
(mg/L).
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
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.

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
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
01
L~2-O1~,62
121
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.
coli 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 coliforms and E.
coli 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
reconunend that consumers take the following
precautions:
To
be inserted by the public water
system, according to instruction from State or local
authorities).
13)
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
frequently 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
01~~2-0~63
122
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 primary 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 50,000 people or fewer that have lead
concentrations below 15 parts per billion
(ppb)
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 replace
all lead service lines contributing in excess of
15 ppb
of 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.
14)
Copper.
The United States Environmental Protection
Agency
(USEPA)
sets drinking water standards and has
determined that copper is a health concern at certain
exposure levels.
Copper,
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 the
corrosion of copper pipes that remain in contact with
water for a prolonged period of time.
Copper
is 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 plumbing materials.
Public water systems
serving 50,000 people or fewer that have copper
concentrations below 1.3 parts per million
(ppm)
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
asbestos.
16)
Barium.
The United States Environmental Protection
Agency
(USEPA)
sets drinking water standards and has
determined that barium is
a health concern at certain
levels of exposure.
This inorganic chemical occurs
naturally in some aquifers that serve as sources of
groundwater.
It is also used in oil and gas drilling
muds, automotive paints,
bricks,
tiles, and jet fuels.
It generally gets into drinking water after dissolving
from naturally occurring minerals
in the ground.
This
chemical may damage the heart and vascular system, and
is associated with high blood pressure in laboratory
animals such as rats exposed to high levels during
their lifetimes.
In humans, USEPA believes that
effects from barium on blood pressure should not occur
below
2 parts per million
(ppm)
in drinking water.
USEPA has set the drinking water standard for barium at
2 parts per million
(ppm)
to protect against the risk
of these adverse health effects.
Drinking water that
I
~
U
124
meets the USEPA standard is associated with little to
none of this risk and is considered safe with respect
to barium.
17)
Cadmium.
The United States Environmental Protection
Agency
(USEPA)
sets drinking water standards and has
determined that cadmium is a health concern at certain
levels of exposure.
Food and the smoking of tobacco
are common sources of general exposure.
This inorganic
metal is
a contaminant in the metals used to galvanize
pipe.
It generally gets into water by corrosion of
galvanized pipes or by improper waste disposal.
This
chemical has been shown to damage the kidney in animals
such as rats and mice when the animals are exposed at
high levels over their lifetimes.
Some industrial
workers who were exposed to relatively large amounts of
this chemical during working careers also suffered
damage to the kidney.
USEPA has set the drinking water
standard for cadmium at 0.005 parts per million
(ppm)
to protect against the risk of these adverse health
effects.
Drinking water that meets the USEPA standard
is associated with little to none of this risk and is
considered safe with respect to cadmium.
18)
Chromium.
The United States Environmental Protection
Agency
(USEPA)
sets drinking water standards and has
determined that chromium is a health concern at certain
levels of exposure.
This inorganic metal occurs
naturally in the ground and is often used in the
electroplating of metals.
It generally gets into water
from runoff from old mining operations and improper
waste disposal from plating operations.
This chemical
has been shown to damage the kidney, nervous system,
and the circulatory system of laboratory animals such
as rats and mice when the animals are exposed at high
levels. Some humans who were exposed to high levels of
this chemical suffered liver and kidney damage,
dermatitis and respiratory problems.
USEPA has set the
drinking water standard for chromium at 0.1 parts per
million
(ppm)
to protect against the risk of these
adverse health effects.
Drinking water that meets the
USEPA standard is associated with little to none of
this risk and is considered safe with respect to
chromium.
19)
Mercury.
The United States Environmental Protection
Agency
(USEPA) sets drinking water standards and has
determined that mercury
is a health concern at certain
levels of exposure.
This inorganic metal is used in
electrical equipment and some water pumps.
It usually
gets into water as a result of improper waste disposal.
This chemical has been shown to damage the kidney of
o
I ~2
—
0 ~6 6
125
laboratory animals such as rats when the animals are
exposed at high levels over their lifetimes.
USEPA has
set the drinking water standard for mercury at 0.002
parts per million
(ppm)
to protect against the risk of
these adverse health effects.
Drinking water that
meets the USEPA standard is associated with little to
none of this risk and is considered safe with respect
to mercury.
20)
Nitrate.
The United States Environmental Protection
Agency
(USEPA)
sets drinking water standards and has
determined that nitrate poses an acute health concern
at certain levels of exposure.
Nitrate is used in
fertilizer and is found in sewage and wastes from human
and/or farm animals and generally gets into drinking
water from those activities.
Excessive levels of
nitrate
in drinking water have caused serious illness
and sometimes death in infants under six months of age.
The serious illness in infants is caused because
nitrate is converted to nitrite in the body.
Nitrite
interferes with the oxygen carrying capacity of the
child’s blood. This is an acute disease in that
symptoms can develop rapidly in infants.
In most
cases, health deteriorates over a period of days.
Symptoms include shortness of breath and blueness of
the skin.
Clearly, expert medical advice should be
sought immediately if these symptoms occur.
The
purpose of this notice is to encourage parents and
other responsible parties to provide infants with an
alternate source of drinking water.
Local and State
health authorities are the best source for information
concerning alternate sources of drinking water for
infants. USEPA has set the drinking water standard at
10 parts per million
(ppm)
for nitrate to protect
against the risk of these adverse effects.
USEPA has
also set a drinking water standard for nitrite at 1
ppm.
To allow for the fact that the toxicity of
nitrate and nitrite are additive.
USEPA has also
established a standard for the sum of nitrate and
nitrite at 10 ppm.
Drinking water that meets the USEPA
standard is associated with little to none of this risk
and is considered safe with respect to nitrate.

Nitrite.
The United States Environmental Protection
Agency
(USEPA)
sets drinking water standards and has
determined that nitrite poses an acute health concern
at certain levels of exposure.
This inorganic chemical
is used in fertilizers and is found in sewage and
wastes from humans and/or farm animals and generally
gets into drinking water as a result of those
activities.
While excessive levels of nitrite in
drinking water have not been observed, other sources of
01
L~,2-QL67
126
nitrite have caused serious illness and sometimes death
in infants under six months of age.
The serious
illness in infants is caused because nitrite interferes
with the oxygen carrying capacity of the child’s blood.
This is an acute disease
in that symptoms can develop
rapidly.
However,
in most cases, health deteriorates
over a period of days.
Symptoms include shortness of
breath and blueness of the skin.
Clearly, expert
medical advice should be sought immediately if these
symptoms occur.
The purpose of this notice is to
encourage parents and other responsible parties to
provide infants with an alternate source of drinking
water.
Local and State health authorities are the best
source for information concerning alternate sources of
drinking water for infants.
USEPA has set the drinking
water standard at 1 part per million
(ppm)
for nitrite
to protect against the risk of these adverse effects.
USEPA has also set a drinking water standard for
