OPINION AND ORDER OF THE BOARD (by J.D. Dumelle):
The City of East Peoria filed a Second Amended Petition
for Variance from Rule 404(c) of the Illinois Pollution Control
Board Rules and Regulations, Chapter 3: Water Pollution, on
May 27, 1980. The City seeks to be allowed to discharge secondary
effluent to outfall 002 during periods of effluent pump failure,
at the same effluent standards as currently specified in the
NPDES permit (IL0028576) for outfall 001, until such time as
the Facilities Plan Improvements are constructed under the
Grants Program.
The East Peoria STP #1 presently has two outfalls permitted
by its NPDES permit. Outfall 001 discharges directly into
the Illinois River, which provides a greater than 5 to 1
effluent dilution, and in accordance with Rule 404(h), the
permit has limits of 20 mg/i BOD5 and 25 mg/l suspended solids.
When flows to the plant exceed 5.8 MGD, the excess flow is
bypassed to a settling basin that discharges through outfall
002 to a 550 foot drainage ditch (ditch “A”), then to a 1250
foot ditch from where it is pumped into the Illinois River.
Since the ditch provides a dilution of less than 1 to 1,
the permit reflects Rule 404(c)’s limitations of 10 mg/i
BOD5 and 12 mg/i suspended solids.
The
existing effluent pump is plagued by failures due
to plant expansion in 1969 which resulted in its being used
in a manner for which it was not designed. As a result, failures
occur approximately 3 months of the year with total yearly
treated effluent discharge to Ditch “A” of approximately
162 MG. Between $25,000 and $30,000 has been spent to improve
the existing pump without success.
In the past when the pump failed the effluent was discharged
into a storm water basin and from there to Ditch “A” and the
Levee District pumps. Because the storm water basin is used
—2—
to collect and provide some primary treatment for wastewater
flows in excess of capacity, if it becomes necessary to bypass
into Ditch “A” before the basin is cleaned to remove settled
sludge, the fully treated effluent will pick up contaminants
present in the basin and its quality will deteriorate between
the plant and the River.
The proposed solution to this problem is to install a
properly designed duplex pumping system with controls and
to enlarge the existing wet well. A pre—application (No.C172310)
has been submitted to the Federal Grants Program (current
priority number is 937). Improvements are estimated to take
23 months after the federal grant is received.
The City has now installed an additional bypass so that
the secondary effluent can de discharged directly into Ditch “A”
and need not pass through the storm water basin during periods
of effluent pump failure. It is for this purpose that the
variance has been requested.
The City estimates the cost of upgrading the facility
at over $122,000. If it were required to dO so with its own
funds, it would suffer hardship to the extent of lost federal
funding (75 of $122,000 or $91,500). Further, immediate
upgrading of the pumping facility is impractical since “a
premature pumping design might not be compatible with the
total plan for plant improvement” (Second Amended Pet. p.2,
para. 6).
The City further states that the environmental impact
of granting the variance will be small because the discharge
will impact only 1800 feet of ditch which is presently permitted
as a storm water bypass and may under certain conditions
receive effluent more degraded than that which Petitioner
now proposes to discharge to it. The land surrounding these
ditches is a low, fill—type area zoned for industrial use,
but is presently undeveloped and likely to remain so until
the implementation of the improvements.
The Agency is does not contradict these statements.
While Board policy has been, and still is, to oppose the
issuance of variances which are sought to relieve liability
from possible, future emergency situations (see PCB 75—63
(December 18, 1975) and PCB 77—200 (August 4, 1977)), the
facts of this particular case remove it from the normal class
of “emergency variances.” Here, the problem is recurrent,
often of considerable duration and presently unavoidable.
Further, the conditions of the Order below should result in
a treatment program which will avoid the problem in the future.
The Board agrees that failure to provide the requested
relief would impose an arbitrary and unreasonable hardship
under these circumstances, and that any environmental damage
—3—
will be minimal. Therefore, the City will be granted a variance
from Rule 404(c) for a period not to exceed 5 years and subject
to the Agency—recommended conditions incorporated in the
Order below.
This Opinion constitutes the Board’s findings of fact
and conclusions of law in this matter.
ORDER
The City of East Peoria is hereby granted a variance
from Rule 404(c) of Chapter 3: Water Pollution Rules and
Regulations for a period to terminate upon grant—funded
upgrading of the pump and wet well at its STP #1 facility,
but in no event to exceed 5 years from the date of this order,
subject to the following conditions:
1. Wet well bypasses shall be discharged to Ditch “A”
and will not be passed through the storm water basin.
2. When secondary effluent is being discharged to the
drainage ditch the point of discharge to the ditch
shall be designated outfall OO1A and shall be monitored
5 times per week by a composite sample. All NPDES
permit requirements for outfall 001 shall apply
to OO1A including the reporting of monitoring results
on DMRs and, in addition, the number of hours per
month that effluent is discharged from outfall OO1A
shall be reported on DMRs.
3. Discharge to the ditch shall only be allowed when
the wet well pump is inoperative.
4. The City shall maintain a spare parts inventory,
operate and maintain the pump consistent with good
engineering practices, and repair the pump as
expeditiously as possible when it fails.
5. The Agency shall modify East Peoria’s NPDES permit
consistent with this Order.
6. The Petitioner shall submit within 45 days of the
granting of this variance, a certificate of acceptance
in the form below:
