Re: Provisional Variance From Limits on Daily Maximum
For Ammonia Nitrogen, CBOD, TSS and pH
Of NPDES Permit 110036218
Dear Mayor Davies
:
The Illinois Environmental Protection Agency (Agency) has completed review of the attached
provisional variance request submitted by the City of Monmouth (City) on March 14, 2006 for
their North Wastewater Treatment Plant .
The City is in the process of installing new urethane
membranes in their aeration basins and needs to take each aeration basin out of service to make
these improvements .
Background
The City of Monmouth owns a wastewater treatment facility, commonly known as
the North
Plant, located approximately 1 .5 miles north of the City of Monmouth on US Route 67 in Warren
County. Environmental Management Corporation (EMC) located at 1033 East Jackson Street in
Monmouth, Illinois operates this treatment facility .
This treatment facility provides anaerobic
biological treatment and flow equalization (covered anaerobic lagoon), aerobic biological
treatment (activated sludge - two aeration basins and two secondary clarifiers), and tertiary
filtration (sand filters) . Several existing lagoons are utilized for additional storage
.
Sludge is
stored in an earthen lagoon.
This facility is designed to treat 1 .334 millions gallons per day
(MGD) design average flow (DAF) and 1 .51 MGD design maximum flow (DMF)
. Discharge is
to an unnamed tributary of Markham Creek
.
The City is requesting a provisional variance to be allowed to install new urethane membranes
in both of their aeration basins .
These basins are currently showing signs of coarse bubble
activity which results in decreased oxygen transfer rates
and treatment efficiency mainly
impacting ammonia levels. Only one basin at a time will be taken out of service. To help reduce
the ammonia levels, the secondary effluent will pumped into several lagoons
.
These lagoons
currently contain algae that could result in elevated CBOD, TSS and pH .
Relief Requested
The City requests a variance from the ammonia nitrogen, CBOD, TSS and pH limitations
contained in NPDES permit 110036218 (Attachment B)
.
This permit requires the City to meet
the following limitations
:
6 to 9 standard units
During the period of the requested provisional variance the City requests daily maximum limits
of 15 mg/l for ammonia, 40 mg/l for CBOD, and 70 mg/l for TSS
.
In addition a variance is
requested for pH at a maximum of 10 .0 .
Agency Determinations
The Agency has reviewed the requested provisional variance and has concluded the following
:
1. The environmental impact from the requested relief is predicted to be minimal ;
2. No other reasonable alternative appears available
;
3 .
No public water supplies will be affected ;
4. No federal regulations will preclude the granting of this request ; and
5. The City will face an arbitrary and unreasonable hardship if the request is not granted .

nitrogen, CBOD, TSS and pH limits of NPDES IL 0036218, subject to the following conditions
:
A. The provisional variance shall begin on March 29, 2006 and shall continue
for a
period of 45 days .
B. The City shall operate its wastewater treatment system to produce the best effluent
possible, and at no time shall the City exceed a daily maximum of 15 mg/l
for
ammonia nitrogen, 40 mg/1 CBOD, 70 mg/l TSS and at no time shall pH exceed
10.0 .
C. Immediate notification to the Agency shall be required if any of the limits imposed
under this provisional variance are exceeded and, in the event any of the limits are
exceeded, measures will be immediately taken to provide supplemental treatment .
D. The City shall notify Roger Callaway of the Agency by telephone at 217/782-9720
when the first aeration basin is taken out of service for repairs and again when the
second aeration basin is returned back to service
.
Written confirmation of each
notice shall be sent within five days to the following address
:

Attention: Roger Callaway
1021 North Grand Avenue East, MC #19
Springfield, Illinois 62794-9276
E. The City shall sign a Certificate of Acceptance of this provisional variance and
forward that certificate to Roger Callaway at the address indicated above within one
day of the date of this order. The certificate should take the following form
:

Final Permit
Gentlemen :
Attached is the final NPDES Permit for your discharge . The Permit as issued covers discharge limitations,
monitoring, and reporting requirements. Failure to meet any portion of the Permit could result in civil
and/or criminal penalties . The Illinois Environmental Protection Agency is ready and willing to assist you
in interpreting any of the conditions of the Permit as they relate specifically to your discharge
.
As discussed in our letter to Mayor Reitman of August 3, 2004, the Agency has made some minor
modifications to the milestones contained in Special Condition 15 of the permit . However, because the
Agency can not at this time guarantee approval of any permit application, we are unable to revise the dates
to be dependent upon the receipt of the Agency approvals or permits . Additionally, pursuant to our
agreement with Region 5, USEPA, the schedule can not extend beyond 36 months from the effective date
of the permit
.
The Permit as issued is effective as of the date indicated on the first page of the Permit . You have the right
to appeal any condition of the Permit to the Illinois Pollution Control Board within a 35 day period
following the issuance date
.
To assist you in meeting the self-monitoring and reporting requirements of your reissued NPDES permit,
a supply of preprinted Discharge Monitoring Report (DMR) forms for your facility is being prepared
.
These forms will be sent to you prior to the initiation of DMR reporting under the reissued permit
.
Additional information and instructions will accompany the preprinted DMRs upon their arrival
.

The secondary effluent will be pumped into the old polishing lagoons to dilute the
ammonia nitrogen down to a reasonable limit . We are asking for high TSS,
CBOD, and PH limits because the lagoons have algae that will cause high TSS,
CBOD, and PH numbers. The longer the lagoons discharge the PH should come
down to around 9.0 on PH. Every effort will be made during this process to
produce the best effluent possible .
5. The project should have no effect on the drinking water supply
.
6, The variance to the discharge limitations should not have a major environmental
impact or major physical effect on the tributary of Markham Creek
. This work is
being done in cooler temperatures to prevent negative impact on the stream

Monmouth's North Wastewater Treatment Plant . One basin will be taken out of
service at a time . This system is showing signs of coarse bubble activity and
decreased oxygen transfer rate, This is having a negative impact on the treatment
process .
8 .
The following steps will have to be taken to install the new membranes
:
Drain the aeration basin,
Remove excess solids from the diffusers,
Remove existing membrane sleeves
.
Install new membranes sleeves
.
Once the new membranes are installed the aeration basins will be brought back
on-line and the plant will again he capable of meeting NPEDS permit limitations
.
9 .
There is no alternative method available to repair the aeration system at the North
Plant. The basins must be drained to perform this work . The North Plant has two
aeration basins that operate in a series. They have to be operated this way to meet
NPDES limitations on BOD and ammonia nitrogen removal. We are not able to
achieve this with one basin. If this work is not done the North Plant Effluent
quality will continue to deteriorate
.
10. We are requesting a variance
of
forty-five days for the repair
of
the Aeration
Basins effective March 29.2006.
11, There has been no provisional variance granted to the City of Monmouth's North
Wastewater Treatment Plant in the last calendar year.
12. The City of Monmouth's North Wastewater Treatment Plant has had TSS and
B0D violations during the month of February and March that this project could
help to improve .
13. There are no matters before the Board and no Board orders that affect the City of
Monmouth's North Wastewater Treatment Plant
.
