OPINION AND ORDER OF THE BOARD
(by Mr.
Dur~ie1leI:
On April
6,
1979 Petitioner filed for a variance from
the limitations on the discharge of mercury into a sewer
system in Rule 702(a)
of Chapter
3:
Water Pollution.
An
Amended
Petition was filed on August
20,
1979.
The Agency
has recommended that a variance be granted for two years,
subject to conditions. Petitioner has accepted this recommendation.
No hearing was held.
Petitioner’s discharge of mercury,
resulting from the
processing of scrap metals, exceeded amounts contained in
the ordinance of The Metropolitan Sanitary District of
Greater Chicago
(MSD) Sewer and Waste Division and Rule
702(a).
In September of 1977, MSD informed Petitioner that
measurements of mercury indicated a discharge of up to 26.3
ugh.
Petitioner does not use mercury in any of its processes.
However, reagents used in the refining process may be a
possible source of mercury contamination.
The mercury
contamination occurred on a basis which could not be predicted
either with respect to the occurrence,
or the resultant
mercury level.
Petitioner,
in cooperation with MSD, attempted
to minimize the amount of mercury discharged by altering
in—house practices and seeking out
a pollution control
equipment manufacturer which had
a system or process available
to reliably meet MSD and Board requirements.
Neither the
MSD suggestion of the “Ventron” system
for mercury removal
nor that of Charles Licht Engineering Associates,
Inc. could
guarantee that Petitioner would meet the Rule 702 requirement
of less than 0.0005 mg/i
as
Hg at any time.
Furthermore,
Petitioner has been advised that the search
for a viable
system will continue, but that, to date,
no system appears
to be available to do the job.
In its Amended Petition for Variance, Petitioner proposes
that a five year variance be granted, as was requested in
its original petition.
Petitioner adds, however,
that if no
new technology exists after two years,
Petitioner will
follow the recommendation of Patterson Associates,
Incorporated,
36—35
—2—
environmental consultants,
for interim controls.
Patterson
recommended the coagulation treatment process on a batch
treatment basis as the most reliable technology available
for mercury pollution abatement.
Patterson also points out
that although the effluent limitations cannot be reliably
met,
the random peaks of mercury contamination can be minimized
at a cost
in excess of $25,000.
The Agency supports the variance from Rule 702(a)
of
Chapter
3 for a period of
two years,
finding that harmful
effects
to the environment caused by granting the variance
would be minimal; that there is no feasible technology
available
to Petitioner to reduce the mercury concentration
in its discharge; and that
it would be an unreasonable
hardship to deny a variance to Petitioner.
The Board finds that
a denial of the variance would
constitute an arbitrary and unreasonable hardship.
The
costs
of completely eliminating the discharge under presently
available technology are high and the suggested measures for
elimination or reduction of the discharge do not guarantee
that Petitioner will meet the requirements
of Rule 702.
Although
a change is pending which would raise the acceptable
levels of mercury in sewer systems
(R76—21), the Board does
not believe that Petitioner should rely on this contingency
but should continue to seek
a viable means of reducing its
mercury discharge. Consequently, the Board concurs with the
reasoning of the Agency in this matter and finds the conditions
imposed on Petitioner during the period of its variance
to
be reasonable.
This Opinion constitutes the Board’s finding of fact
and conclusions
of
law
in this matter.
ORDER
It
is the Order of the Pollution Control Board that
Petitioner
be
granted a variance from the restrictions on
the discharge of mercury into a sewer system contained in
Rule 702(a) of Chapter
3: Water Pollution for a period of
two years
from the date of this Order,
subject to the following
conditions:
1)
Petitioner shall conduct a study of means of removing
mercury—containing scrap metals prior
to processing.
2)
Petitioner shall conduct further studies
(a) to find
suppliers of mercury—free reagents to use for its
refining process and
(b) to identify other possible
sources
of mercury contamination in its processes and
means of reducing such contamination.
36—36
—3—
3)
Petitioner
shall submit
a report as to information
developed in subparagraphs
(1) and
(2) to the Illinois
Environmental Protection Agency,
Compliance Unit,
Division of Water Pollution Control,
2200 Churchill
Road,
Springfield,
Illinois
62706 within ten months of
the date of this Order.
4)
Petitioner shall keep abreast of published research and
development
in the area
of mercury control and evaluate
its suitability for its processes.
Petitioner shall
submit a report as to information developed in this
regard to the Illinois Environmental Protection Agency,
Compliance Unit, Division of Water Pollution Control,
2200 Churchill Road, Springfield,
Illinois 62706 within
20 months of the date of this Order.
5)
Within 45 days
of the date of this Order, Petitioner
shall execute of certification of acceptance and agreement
to be bound to the terms and conditions of this variance.
This
45 day period shall
he held in abeyance
if this
matter is appealed.
The certification shall he forwarded
to the Illinois Environmental Protection Agency, Compliance
Unit,
Division of Water Pollution Control, 2200 Churchill
Road,
Springfield,
Illinois
62706 and shall read as
follows:
