PROPOSAL FOR PUBLIC COMMENT
PROPOSED ORDER OF THE BOARD
(by 3. Anderson):
Pursuant to Section 17.5 of the Environmental Protection Act
(Act), the Board is proposing to update its regulations which are
identical in substance to USEPA regulations implementing the Safe
Drinking Water Act
(SDWA).
The Board rules are contained in 35
Ill.
Adm. Code 611.
Section 17.5 of the Act provides for quick adoption of
regulations which are “identical
in substance” to federal
regulations;
Section 17.5 provides that Title VII of the Act and
Section 5 of the Illinois 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 text of the Proposed amendments is attached to this
Order.
The text will be published in the Illinois Register in
the near future.
The Board will receive public comment for 45
days after the date of publication in the Illinois Register.~
Because of its length, the text of the proposed rules will not be
published in the Environmental Register, or in the Board’s
Opinion volumes.
IT IS SO ORDERED

(“URTH level”)
means the concentration of a contaminant which 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 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
13
1—275
28
which clearly exceed the health benefits to be derived.

This Section is intended as a State equivalent of Section 1416 of
the SDWA.
a)
The Board may grant a supplier a variance from any
requirement respecting an MCL or treatment technique
requirement of an NPDWR in this Part.
1)
The supplier shall file a variance petition
pursuant, to
35 Ill. Adm. Code 104, except as
modified or supplemented by this Section.
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)
Due to compelling factors (which may include
economic factors), the supplier is unable to
comply with the MCL or treatment technique
requirement;
2)
The supplier was:
A)
In operation on the effective date, of the MCL
or treatment technique requirement;
or
B)
Not in operation on the effective date of the
MCL or treatment technique requirement and no
reasonable alternative source of drinking
water is available to the supplier; and
3)
The variance will not result in an unreasonable
risk to health.
13
1—276

c)
The Board will prescribe a schedule for:
1)
Compliance,
including increments of progress, by
the supplier, with each MCL and treatment
technique requirement with respect to which the
variance was granted; and
2)
Implementation by the supplier of each additional
control measure for each contaminant, subject to
the MCL or treatment technique 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;
but no schedule shall extend more than 12 months after
the date of the variance, except as follows:
1)
The Board may extend the date for a period not to
exceed three years beyond the date of the variance
if the supplier establishes:
that it is taking
all practicable steps to meet the standard;
and:
A)
The~supplier cannot meet the standard without
capital improvements which cannot be
completed within 12 months;
B)
In the case of a supplier which needs
financial assistance for the necessary
improvements, the supplier has entered into
an agreement to obtain such financial
assistance;
or
C)
The supplier has entered into an enforceable
agreement to become a part of a regional PWS;
and
2)
In the case of a PWS with 500 or fewer service
connections, and which needs financial assistance
for the necessary improvements, a variance under
subsections
(d) (1) (A) or
(B) may be renewed for
one or more additional two year periods if the
supplier establishes that it is taking all
practicable steps to meet the final date for’
compliance.
e)
The Board will provide notice and opportunity for a
public hearing as provided’in 35 Iii.

methods, incorporated by reference in Section 611.102:
1)
Multiple-Tube Fermentation
(MTF) Technique,
as set
forth in:
A)

or
4)
lIMO-MUG test.
d)
In lieu of the 10-tube
MTF
Technique specified in
subsection
(c) (1), a supplier may use the
MTF
Technique
using either five tubes
(20—ml sample portions or a
single culture bottle containing the culture medium for
the
MTF
Technique,
i.e.,
lauryl tryptose broth
(formulated as described in Standard Methods, 16th
Edition, Method 908A,
incorporated by reference in
Section 611.102)
as long as a 100-ml water sample is
used in the analysis.
e)
Suppliers shall conduct fecal coliform analysis in
accordance with the following procedure:
13 1—287
40
1)
When the MTF Technique or P-A Coliform Test is
used to test for total coliforms,
shake the
lactose-positive presumptive tube or P-A bottle
vigorously and transfer the growth with a sterile
3-mm
loop or sterile applicator stick into
brilliant green lactose bile broth and EC medium,
defined’ below, to determine the presence of total
and
fecal
coliforms,
respectively.
2)
For Microbiological Methods, referenced above,
which use a membranee filter, transfer the ‘total
coliform—positive culture by one of the following
methods:
remove the membrane containing the total
coliform colonies from the substrate with a
sterile forceps and carefully curl and insert the
membrane into a tube of EC medium.
(The
laboratory may first remove a small portion ‘of
selected colonies for verification);
swab the
entire membrane filter surface with a sterile
cotton swab and transfer the inoculuin to EC medium
(do not leave the cotton swab in the EC medium):
or inoculate individual total coliform—positive
colonies into EC medium.
Gently shake the
inoculated ~—tubes
of EC medium to insure
adequats mixing and incubate in a waterbath at
44.5
+/—
0.2 degrees C for 24
+1—
2 hours.
Gas
production of any amount in the inner fermentation
tube of the EC medium indicates a positive fecal
coliform test.
3)
The preparation of EC medium is described in
Standard Methods,
16th Edition, Method 908C.
4)
Suppliers need only determine the presence or
absence of fecal coliforms,
a determination of
fecal coliform density is not required.
fj
If a supplier uses the MMO-MUG test for total coliforta
detection,
the supplier shall test all total coliform-
positive cultures for fluorescence.
fl
To test for fluorescence, use an ultraviolet light
(366 nm)
in the dark after incubating the tube or
container at 35
+1—
0.5 degrees Celsius for 24 to
28 hours.
If fluorescence is observed, the sample

fluoride.
mercury
and selenium is determined by p running annual
average at each sampling point.
Li
If the average at any sampling point is greater

21
If any one sample would cause the annual average
to be exceeded, then the supplier is out of
compliance immediately.

Any sample below the detection limit must be
calculated at zero for the purpose of determining
the annual average.
hi
For suppliers which are monitoring annually, or less
frequently, compliance with the MCLs for asbestos,
barium,

fluoride, mercury and
selenium 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.

Definitions.
As used in this Section:
“Distribution system” includes all points
downstream of an “entry point”.
“Entry point” means a point lust downstream of the
final treatment operation. but upstream of the
first user and upstream of any mixing with other
water.
If raw water is used without treatment,
the “entry point” is the raw water.source.
If a
PWS receives treated water from another PWS, the
13 1—325
78
“entry point” is a point lust downstream of the
other
PWS.
but
u~stream of
the
first
user
on
the
PWS, and upstream of any mixing with other water.
“GWS”
is
as
defined
in
Section
611.600.
“Mixed
system”
is
as
defined
in
Section
611.600.
“Representative”
means
that
a
sample
is
expected
to
reflect
the
properties
of
water
averaged
over
the_period
of
time
and
portion
of
the
PWS
to
be
sampled.
To
be
representative,
a
sample
must
be
taken
under
normal
seasonal
operating
conditions.
“Source”
means
a
well,
reservoir
or
other
source
of raw water.
“SWS” is as defined in Section 611.600.
“Treatment” means any process:
which changes the
physical
or
chemical
properties
of
water;
which
is
under
the
control
of
the
supplier;
and,
which
is not a “point of use” or “point of entry
treatment
device”
as
defined
in
Section
611.101.
“Treatment”
includes,
but
is
not
limited
to:
aeration.
coagulation.
sedimentation,
filtration.
activated
carbon,
chlorination
and
fluoridation.

C)
If the
CWS
or
NTCWS
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
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

distribution
or
entry—point
samples,
as
required
in
this
paragraph,
representing
all

result
and
used
for
compliance
determination
in
accordance
with
subsection
(i).
The
Agency

the
Agency
shall
reduce
the frequency of vinyl chloride monitoring to once
every
three
years
for
that
sample
location
or
other
sample
locations
which
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
VOC
liotcd
~
~
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 VOCathe eight
organic
contaminants.
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.
A)
Add
5
ml
or
equal
larger
amounts
of

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
4 degrees C
during
this
step
to
minimize
volatilization
losses.
C)
Mix
well
and
draw
out
a
5—nil
aliquot
for
analysis.
D)
Follow sample introduction, purging and
desorption
steps
described
in

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
NTCWS
is deemed to be out of compliance.
If a
CWS
or
.NTCWS
has
a
distribution
system
separable
from
other
parts
of
the
distribution
system
with
no
interconnections,
only
that
part
of
the
system
that
exceeds
any
NCL
as
specified.
in
Section
611.311(a)
is
deemed
out
of
compliance.
The
Agency
shall,
by
opecial
cxccption
pcrmit~, reduce the public notice requirement to that
portion
of
the
CWS
which 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
no
VOC3none
of
the
eight
organic
contaminants
were
detected,
compliance
is
based on that one sample.

Definitions.
As used in this Section:
“Distribution system” includes all points
downstream of an “entry point”.
“Entry point” means a point just downstream of the
final treatment operation. but upstream of the
first user and upstream of any mixing with other
water.
If raw water is used without treatment.
131—363
116
the
“entry
point”
is
the
raw
water
source.
If
a
PWS
receives
treated
water
from
another
PWS.
the
“entry
point”
is
a
point
lust
downstream
of
the
other
PWS.
but
upstream
of
the
first
user
on
the
PWSI
and
upstream
of
any
mixing
with
other
water.
“GWS”
is
as
defined
in
Section
611.640.
“Mixed
system”
is
as
defined
in
Section
611.640.
“Representative”
means
that
a
sample
is
expected
to
reflect
the
properties
of
water
averaged
over
the
period
of
time
and
portion
of
the
PWS
to
be
sampled.
To be representative.
a sample must be
taken under normal seasonal operating conditions.
“Source”
means
a
well,
reservoir
or
other
source
of raw water.
“SWS”
is as defined
in
Section
611.640.
“Treatment” means any process:
which changes the
physical or chemical properties of water;
which
is
under
the
control
of
the
supplier;
and,
which
is not a “point of use” or “point of entry
treatment
device”
as
defined
in
Section
611.101.
“Treatment”
includes,
but
is
not limited to:
aeration,
coagulation,
sedimentation,
filtration,
activated
carbon,
chlorination
and
fluoridation.

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
(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 federa.1
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).
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 auaccdcaused 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
oontaminatodcontaminated 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
131—373
126
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. ccli.
(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
ocntaminatcdcontaminated 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
recommend that consumers take the following
precautions:

Asbestos.
The United States Environmental Protection
Agency (USEPA) sets drinking water standards and has
determined that asbestos fibers areater than
10 micrometers in length are a health concern at
certain levels of exposure.
Asbestos is a naturally
oöcurring 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 ~i~es in the distribution
system..
The ma-icr uses of asbestos were in the
131—374

paint, and caulking:
in transportation-related
a~~lications;
and
in the production of textiles and
plastics.
Asbestos was
once
a
~o~ular
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 ~drinkingwater 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 laborato~animals also may increase
the risk of cancer in humans who are exposed over long
periods of time.
!JSEPA 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.

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.

to protect against the risk of these
adverse health effects.
Drinking water that meets the
TJSEPA standard is associated with little to none of
this risk and is considered safe with respect to
chromium.
~
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 eauipment 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
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 ~er million (ppm~to protect against the risk of
these adverse health effects.
Drinking water that
meets the USEPA standard is associated with little to

Nitrate.
The United States Environmental Protection
A~encv(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.

are
the
best
source
for
information
concerning alternate sources of drinking water for

Nitrite.
The United States Environmental Protection
Agency
(USEPA)
sets drinking water standards and has
determined that nitrite roses 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
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. e~ert
medical advice should be sought immediately if these
s~otomsoccur.
The purpose pf this notice is to
encourage parents and other res~onsib1eparties 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 (~~m)for nitrite
to protect against the risk of these adverse effects.
USEPA_has also set a drinking water standard for
nitrate (converted to nitrite in humans) at 10 ~
