Good
afternoon.
Welcome
to the Illinois
Pollution
Control
Board.
My name
is Amy Antoniolli
and I’m
the hearing
officer
assigned
to this
rulemaking.
The board has captioned
this
proceeding
in
the matter
of revisions
to
radium water quality
standards
proposed
new
Illinois
Administrative
Code,
302.307
and
amendments
to
35 Illinois
Administrative
Code 302.207
and 302.525 which
the board
has docketed
as
RO4-21.
In this proceeding
the agency
is
seeking
to
amend
the board’s
water
quality,
radium quality
standards.
This
rulemaking
was filed
on January
13,
2004,
by the
Illinois
Environmental
Protection
Agency.
The board accepted
the proposal
for hearing
on January
22,
2004.
This
is the second
The first
hearing
took place
on
2004,
in the James

Today’s
hearing
is governed
by the
3
board’s procedural
rules
for regulatory
4
proceedings.
All
information
that
is
5
relevant
and not repetitious
or privileged
6
will
be entered
into
the record.
All
7
witnesses
will
be
sworn and subject
to
8
cross
questioning.
9
The purpose
of today’s
hearing
is two
10
fold.
First,
this rulemaking
is subject
to
11
section
273
of
the Environmental
Protection
12
Act.
Section
273
of
the act requires
the
13
board
to request
the Department
of Commerce
14
and Economic
Opportunity
or the DCEO
to
15
conduct
an economic
impact
study
on certain
16
proposed
rules prior
to
their
adoption.
17
The board must
make
the
impact
study
or
the
18
DCEO explanation
of why
it won’t
conduct
19
the
study
available
to the public
at
least
20
20
days before
the public hearing
on the
21
economic
impact proposed
rules.
The board
22
requested
by letter
in this rulemaking
23
dated
February
18,
2004,
that
the DCEO
24
conduct
an economic
impact
study
of this

rulemaking.
2
On April
2,
2004,
a letter
from the
3
DCEO
explains
that
the DCEO will
not
4
perform
an economic
impact
study
for
this
5
rulemaking.
Due
to physical
constraints,
6
we’ve
made
that letter available
on the
7
table
at the
side
of the
room today
or it’s
8
also available
on the board’s
website
and
9
has been
since
it was
filed with
the board.
10
The second purpose
of this
rulemaking
today
11
is
to allow members
of the public
the
12
opportunity
to testify
and to
ask questions
13
of
the proponents.
14
Mr.
Dennis
Duffield,
Director
of
15
Public
Works
and Utilities
of
the City
of
16
Joliet
has prefiled
testimony
for today’s
17
hearing.
We will
start
today with
a brief
18
summary
of
the proposal
by the agency and
19
then allow
Mr.
Duffield
to give
an oral
20
summary
of
his testimony
or
if he chooses
21
to read his prefiled
testimony
into
the
22
record.
Finally
we will
have
a questioning
23
period and when we get
to
the questioning
24
period,
anyone
can ask
a question
but for

the Reporter,
please
speak up and try not
2
to
speak
over each other
so that
the

transcript
comes
out
clear.
Please note
4
that
the questions,
any questions
asked by
5
Member Melas
or any member
of
the
staff
are
6
intended
to help build
a complete
record
7
for the board’s
decision
and not
to
8
expression
any preconceived
notion
or bias.
9
Also
at
the
side
of
the room
today
10
I’ve made
copies
available
of
the board’s
11
order
accepting
this matter
for hearing,
12
the notice
of hearings,
the agency’s
13
proposal,
the prefiled
testimony
both by
14
Mr.
Duffield
and by the agency,
and at
this
15
time
I will
ask Member Melas
if you would
16
like
to add anything.

MR.
MELAS:
No.
I
just welcome

So,
we will
turn
it

over
to the agency
now.
21
MS.
WILLIAMS:
Thank
you.
Good
22
afternoon,
my name
is Debra Williams
and
23
I’m assistant
counsel
before
the Bureau
of
24
Water
at
the
Illinois
EPA and
as requested
JO ELAINE FOSTER

1
by the Hearing
Officer,
I will
now provide
2
a brief
introduction
to the agency’s
3
rulemaking
proposal
in this matter which
4
was presented
in detail
at
the April
1
5
hearing
in Chicago.
6
Under
Section
303C
of the
Clean Water
7
Act,
the
Illinois
EPA has the obligation
to
8
no less
than every
three
years
conduct
9
reviews
of
its water quality
standards
and
10
update
those
standards
where
needed.
As
11
part
of
that ongoing process.
The agency
12
has proposed
this update
to the water
13
quality
standards
for rating.
Currently
14
the standard
applicable
to all general
use
15
waterways
in the
state
of Illinois
is
a
16
radium
226 standard
of
one pico-curie
per
17
liter.
U.S.
EPA has established
a maximum
18
contaminant
level
or MCL
of
5 pico-curies
19
per liter
for radium
226
and radium
228
20
combined.
Research
by the agency has
21
concluded
that
the technical
basis
for
the
22
radium water quality
standard
was
23
protection
of human health
from consumption
24
of radium
in drinking
water
and that

& ASSOCIATES,
P.C.
(618)
877-7016
F:
(618)
655-0660
8
1
pico-curies
per liter
is clearly
the
level
2
protective
of
that use as established
under
3
the
Safe Drinking
Water
Act.
Therefore,
4
the agency
has proposed
changing
the
5
standard
to
5 pico-curies
per
liter and
6
placing
that standard
in the board’s
public
7
and food processing
water
supply standard
8
thereby making
the standard
applicable
only
9
in drinking
water
supply
intake.
10
The new standard
is proposed
to be
11
placed
in section
302.307
of subpart
C of
12
part
302
of
the board’s
regulations.
The
13
agency has also proposed
to repeal
the
14
general
use standard
in section 302.207
of
15
subpart
C and the Lake Michigan basin
16
standard
of Section
302.525
in subpart
E.
17
I have
with me
today
several
agency
18
staff
members
who are again available
to
19
answer
any additional
questions
by the
20
board
or members
of
the public.

the proposal
and for thanking

in advance
for consideration
of our

proposal.

HEARING
OFFICER:
Thank you,
Miss

Williams.
At this
time
we could
go ahead
11
and have
Mr.
Duffield
sworn
in,
then he can
12
choose
to either give
a summary
of his
13
prefiled
testimony
or go ahead and read the
14
testimony
into

OFFICER:

17
MR.
DUFFIELD:
My name
is Dennis
18
Duffield,
I am the Director
of Public Works
19
and Utilities
for
the City
of Joliet
and
I
20
would
like
to summarize
my testimony
as
21
I’ve
already prefiled.
22
The Joliet public water
supply
has
23
radium
in
it that exceeds
the drinking
24
water
standard.
We also operate
two
JO ELAINE FOSTER & ASSOCIATES,
P.C.
(618)
877-7016
F:
(618)
655-0660
10
1
wastewater
treatment
plants
that receive
2
the wastewater
from this water
supply which
3
results
in radium
as an influent
to the
4
treatment
plants.
On
a numerical
average,
5
Joliet
has about
10.4 pico-curies
of
6
combined
radium
226 and
228
in its water
7
supply.
That
ranges throughout
the system
8
based
on actual
wells
that
are operated.
9
Of that,
between
the range
of
6.2
and
10.0
10
pico-curies
per liter arise
as influent
to
11
the two treatment
plants.
The treatment
12
plants
off
of
the two
samples
we’ve
13
analyzed remove
somewhere
between
2
and
81
14
percent
of the radium and have discharged
15
radium
in the
effluent
in the plants
at
a
16
range
of
1.9
to
6.1 pico-curies
per liter.
17
Our east
side plant
discharges
into
18
Hickory
Creek
at
the confluence
with
the
19
Des
Plaines
River.
We sample upstream
and
20
downstream
of our discharge
point
and have
21
found
that
the upstream
radium
22
concentration
is 1.3 pico-curies
per
liter
23
of combined
radium
226 and
228
and the
24
downstream
which
is essentially
within

F:
(618)
655-0660
11
1
Des
Plaines
River
is
1.4 pico-curies
per
2
liter,
or almost
no change.
3
Joliet believes
the proposed
rule
is
4
necessary
to allow Joliet
to complete
our
5
plans
to treat
for radium
in
the water
6
supply system using
the hydrous
manganese
7
oxide
treatment
method which results
in the
8
discharge
of radium
to the sanitary
sewer
9
as
it’s currently
discharged
and then
10
ultimately
to the Des Plaines
River and
11
Hickory
Creek
and we would
like
to do
so
12
without
a water quality
standard
violation.
13
We’ve noted
that
in testimony
provided
14
by Bob Mosher
of
the
Illinois
EPA
that
the
15
original
standard
for radium was
16
established
based
on problems
with people
17
ingesting
radium.
The proposed
rule
18
provided by the agency addresses
this by
19
establishing
a standard
for public water
20
supply
intakes
and food processing
21
facilities.
We support
the implementation
22
of this
rule.
That
summarizes
my
23
testimony.
24
HEARING
OFFICER:
Very good.

you,
Mr.
Duffield,
for your
testimony.
If
2
there
is no objection,
I have
a copy
of
the
3
prefiled
testimony
in front
of me
and
I
4
will move
to enter
that
as Exhibit
No.
1.
5
Seeing
no objection,
I
enter
this exhibit.
6
Does
anyone
here have
any questions
for
7
Mr.
Duffield?
Go ahead.
8
MR.
KELLER:
You’re building
a new
9
treatment
plant
on the
far west
side
of
10
Joliet
and would
that treatment
plant
have
11
similar
type problems
with radium
or not.
12
MR.
DUFFIELD:
I expect
that
it would,
13
that
it would be
the same because
at that
14
location,
we have
all
deep wells.
We won’t
15
have
any shallow
wells
so
the incoming
16
radium concentration
might
be higher
at
17
that plant.
18
HEARING
OFFICER:
And
I have
a
19
question
out
of curiosity.
Have
you or
20
your
staff
investigated
other
methods
of
21
removing
the radium from
the drinking
water
22
besides
the
co- precipitation
of radium?
23
MR.
DUFFIELD:
Yes,
we have
analyzed
24
two other
methods.
One method does
not

& ASSOCIATES,
P.C.
(618)
877-7016
F:
(618)
655-0660
13
1
discharge
to
the sanitary
sewer.
That
2
method concentrates
the radium and ships
it
3
off to
a low level
hazard,
radium waste
4
disposal
site which
we think
has other
5
problems
and
so out
of cost analysis
and
a
6
risk
to our customers,
we have
selected
the
7
hydrous
manganese
oxide process
and will
be
8
submitting
that
as
a part
of our design
9
report
for review.
10
HEARING
OFFICER:
At this
time,
is
11
there
anyone
else
or any questions
for the
12
witnesses
from the agency?
Okay.
We thank
13
everyone
who
is here
for being here
today
14
and for the testimony
that you have
15
provided.
For
the record,
the board will
16
accept public
comments
in this
rulemaking
17
to be included
in the first
notice
18
opinionated
order
until
June
3,

There
will

PRE-FILED TESTIMONY OF DENNIS DUFFIELD
My name
is
Dennis Duffield.
I am the Director of Public Works
and Utilities for
the
City of Joliet.
I am responsible for the
planning,
design,
construction
and
operations of water
and wastewater systems
for Joliet.
I have worked for the City ofJoliet
for approximately
24
years
and have been responsible for the water and
wastewater systems
for all
but the first four months of
9
the 24 years.
Prior to working at the City ofJoliet, I worked for the City of Virginia Beach, Virginia
for approximately
five
years with
responsibilities for the
operations of the water
distribution
and
wastewater collection systems.
Previous experience was in the Indian Health Program of the United
States Public Health
Service.
I received
a Bachelor of Science
in
Civil
Engineering from
Bradley
University in
1972.
I have been a Licensed Professional Engineer in the State ofIllinois since
1980.
Today I
will
testify
in
regards
to
the
Illinois
Environmental Protection
Agency’s
(IEPA) proposed changes to the water quality
standards
for radium and
the impact of this proposal
on the water supplies and wastewater treatment plants.
The
City
of Joliet
operates
a
public
water
supply
using
groundwater
containing
radium. After
use by consumers, the water is
discharged to
the two wastewater treatment plants that
the City of Joliet also operates.
Discharge from the plants is to
Hickory Creek at the confluence with
Q
the DesPlaines River and directly to the DesPlaines
River.
Prefiled Testimony ofDennis Duffield

The City
of Joliet’s
water supply
system
currently
consists
of
15
deep
wells
that
produce water that exceeds the drinking water standard for combined radium 226 and radium 228
of
5.0 pico-curies per liter and
5 shallow wells that produce water that complies with the standard.
This
water is currently supplied to consumers
without treatment.
The wastewater from the community is
collected
and
transported
to
two
wastewater
treatment
plants.
Since
no
radium
treatment
is
provided, the radium that enters the system
arrives at the wastewater treatment plants.
Joliet recently measured the concentration of radium in the influent to the treatment
plants.
The results area as follows:
Joliet Eastside Wastewater Treatment Plant

Radium 228

These
concentrations of radium arriving at the wastewater plants are
very
near
to
the
10.4 pico-curies per liter
average concentration measured in Joliet’s deep wells.
Joliet
is
planning to
remove radium from the drinking water by
implementing the
co-precipitation of radium with pre-formed hydrous manganese
oxide.
In this
process, a solution of
hydrous manganese
oxide
is
mixed
with
the
well
water
and
forms
a
precipitate.
The
radium
is
attached to the precipitate.
The precipitate is filtered from the water which removes the radium.
Prefiled Testimony of Dennis Duffield

o~
The filters collect the precipitate and begin to filter water at a slower rate.
The flow
of water is then reversed and the precipitate is
washed from
the filter and collected.
This
stream is
known as the “backwash”.
This wastewater from the water treatment process is
then discharged to
the sanitary sewer.
This wastewater contains the radium removed from the drinking water.
The backwash
combines with discharge from homes and
businesses
in the sanitary
sewer and becomes the influent to the wastewater treatment plants.
Since the radium is removed and
subsequently
recombined, there
is
no
change in
the quantity of radium anticipated to arrive
at the
wastewater treatment plants.
Measurements
of the
concentration
of radium
discharged
from
the
wastewater.
treatment plants were also taken.
The results ofthe measurements are as follows:
Joliet Eastside Wastewater Treatment Plant

All ofthe discharge results demonstrate that this proposed rule is necessary to
allow
the continued discharge from existing
wastewater treatment
plants.
The concentration
of radium in
the
treatment
plant
discharge
is
reduced
from
the
influent
concentration.
From
this
limited
0
information, the range ofthe removal for combined radium226 and 228
is from 2
to 81.
Prefiled Testimony ofDennis Duffield

The
discharge from
the
Joliet
Eastside Wastewater Treatment
Plant is to
Hickory
Creek at the confluence with the DesPlaines
River.
Joliet
collected stream samples from
a location
upstream ofthe plant discharge on Hickory Creek and a location downstream ofthe plant
discharge
on the DesPlaines River submitted for radium concentration determinations.
The results ofsamples
collected March 8, 2004 are as follows:

Joliet has collected
additional influent and effluent
samples and is
waiting for the laboratory results.
It is our intent to provide this information if it becomes available
before the hearing record is closed.
The
proposed
rule
is
necessary
to
allow
the
water
supplies
to
proceed
with
construction of the required facilities to
remove radium from
the drinking water and to
be
assured
that the discharge of the backwash or other return flows
from the radium removal treatment
system
can be
discharged to
the
sanitary sewer
without
causing an
effluent
violation
for the wastewater
treatment plant owner.
This will also allow the wastewater treatment plant owner to
be
assured that
it will not
be necessary to
develop additional
standards for the discharge of water treatment
wastes
containing radium
to
the
sanitary
sewer
system.
Joliet
currently
prohibits
the
discharge
of any
radioactive
wastes of such concentrations that
will
cause
the
treatment
plant
to
violate any water
quality standards.
Without the approval of the IEPA’s proposed rule,
Joliet would
have to consider
other water treatment methods that do not discharge the water treatment waste stream containing the
radium to the sanitary sewers.
This would be required as the discharge ofradium bearing wastes to
the sanitary sewers could result in a violation ofthe existing water quality standards.
As
indicated
in
the
testimony of Robert Mosher at the
April
1,
2004
hearing, the
only
threat
to
human health
from
radium
is
through
ingesting
the radium through
drinking
water.
The IEPA’s
proposed water quality
standards
adequately address any potential
problems with food
processing
and public
water supply intakes
and
allow the continuation of discharges by wastewater
treatment facilities.
The
City of Joliet
supports the implementation
of the water quality
standards
for
radium.
