Re :
Provisional Variance From the Dilution Ratio Requirement
Of NPDES Permit IL00227464
Dear Mayor Sandidge :
The Illinois Environmental Protection Agency (Agency) has completed its technical
review of the attached provisional variance request (Attachment A) from the City of
Alton (City). The Agency received a faxed request, dated January 8, 2007, from the City
on January 12, 2007, and the hard copy of the same on January 18, 2007 . The City needs
to perform essential maintenance on the Discharge 001 outfall pipe to the Mississippi
River. The City is requesting this provisional variance so that it can make the necessary
repairs to this outfall sewer. Based on its review, the Agency GRANTS a provisional
variance subject to the specific conditions set forth below .
Background
The City of Alton owns and operates a wastewater treatment facility located at 19
Chessen Lane, off of Broadway, in Alton, Illinois . This treatment facility consists of an
activated sludge plant designed to treat 10 .50 million gallons per day (MGD) design
average flow and 26.25 MGD design maximum flow . Treatment units consist of
mechanical fine screens, grit chambers, two primary clarifiers, five activated sludge
tanks, two secondary clarifiers, and chlorination . The facility has two discharge points :
Outfall 001, which discharges to the Mississippi River ; and Outfall 009, an emergency
high level bypass, which discharges to Wood River Creek .
The City must remove and replace a 34-foot long section of the 42" outfall sewer pipe
before it can complete the repairs to the Discharge 001 outfall pipe
. To facilitate removal
of this pipe, the effluent from the Alton wastewater treatment plant needs to be diverted
from Discharge 001 to Discharge 009 .
Relief Requested
The City requests a provisional variance from NPDES permit IL0027464, Special
Condition 13 (Attachment B)
. Special Condition 13 of the permit provides in pertinent
part :
Discharge 009 is an emergency high level bypass . Discharges from this
overflow, other than when the Mississippi River is at or above 25-year flood
elevation and when 5
:1 dilution exists in Wood River Creek, are subject to the
following conditions :
(2) Bypass not exceeding limitation .
The Permittee may allow any bypass to
occur which does not cause effluent limitations to be exceeded, but only if at least
a 5:1
dilution ratio is maintained in Wood River Creek and if it also is for
essential maintenance to assure efficient operation
. . . .
*
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 reasonable alternatives appear available ;
3.
No public water supplies should be affected
;
4 .
No federal regulations will preclude the granting of this request
; and
The City will face an arbitrary and unreasonable hardship if the request is not
granted.
Conditions
The Agency hereby GRANTS the City of Alton a provisional variance from Special
Condition 13 of NPDES Permit IL0027464 requiring the City to maintain a 5
:1 dilution
ratio at Discharge 009, subject to the following conditions
:
A.
The provisional variance shall begin on January 30, 2007, and end no later than
February 28, 2007, during which time the City does not have to meet the 5
:1
dilution ratio requirement specified in NPDES permit IL0027464 .
B.
The City shall operate its system to produce the best effluent possible
. All other
requirements of NPDES permit IL0027464 will be maintained during the variance
period.
C.
The City shall notify Barb Conner of the Agency by telephone at 217/782-9720
when the repairs begin and effluent is diverted from Discharge 001 to Discharge
009 and again when repairs are complete and the effluent is diverted back to
Discharge 001
. Written confirmation of each notice shall be sent within five days
to the following address :
Illinois Environmental Protection Agency
Bureau of Water
- Water Pollution Control
Attention: Barb Conner
1021 North Grand Avenue East, MC #19
Springfield, Illinois
62794-9276
D .
The City shall sign a certificate of acceptance of this provisional variance and
forward that certificate to Barb Conner at the address indicated above within one
day of the date of this order
. The certification should take the following form :
I (We) ,
hereby accept and agree to be bound by all terms
and conditions of the provisional variance granted by the Agency in
Petitioner dated
Authorized Agent
Title
Date
The City shall continue to monitor and maintain compliance with all other parameters
and conditions specified in its NPDES Permit No
. 1L0027464.
Conclusion
The Agency grants this provisional variance in accordance with its authority contained in
Sections 35(b), 36 (c),
and 37(b) of the Illinois Environmental Protection Act (415 ILCS
5/35(b), 36(c), and 37(b) (2004)
. The decision to grant this provisional variance is not
intended to address compliance with any other applicable laws or regulations

Re: City of Alton
Dear Ms. Conner :
We are writing as a follow-up to our correspondence to you dated December 19,
2006 in which we requested approval to use Discharge 009-Secondary Outfall to Wood
River Creek while we perform "essential maintenance" to the 42" plant outfall sewer to
the Mississippi River, The Agency's verbal response to that letter was that the City
would need to formally request a Provisional Variance .
The purpose of this letter is to request a Provisional Variance from the Agency to
discharge treated plant effluent through permitted Discharge 009 when the Mississippi
River is below the 25 year flood elevation and when dilution in Wood River Creek is less
than 5:1 .
In accordance with Title 35, Subtitle A, Chapter II, Part 180, Subpart B, Section
180.202 b), Descriptions and justifications for the Variance are
:
1)
Variance is being requested from NPDES Permit No . IL0027464, Special
Condition 13 . The variance would allow the Alton Wastewater Treatment
Plant to discharge to Wood River Creek through Discharge 009 when the
dilution ratio is less than 5
:1 and the Mississippi River is below the 25
year flood elevation
. All other requirements of NPDES Permit No
.
1L0027464 .
2)
The activity that will be performed during this variance is the removal and
replacement a section of the City's 40 year old 42" outfall sewer that
normally routes the plant discharge to the Mississippi River
. This
maintenance activity is located approximately 1,000 feet downstream of
Discharge 009 on the west bank of Wood River Creek . Distance from
Discharge 009 to the Mississippi River is 4,700 feet .
The creek is
bordered on both banks by the Wood River Drainage and Levee District's
Levees
. No residences or businesses are located in the area between
the levees.

3)
The removal section of 42" outfall sewer is 34 feet long and is welded
steel pipe The pipe has corroded and is no longer structurally sound
.
The proposed replacement pipe will be 42" ductile iron pipe, 34 feet long,
with flanged connections.
4)
The attached exhibit A consists of DMR's for the same time period in
2003, 2004, 2005 and 2006, showing that the tested values do not
exceed permitted values . The receiving waterway Is Wood River Creek,
a constantly flowing waterway which drains approximately 122 square
miles.
5)
Not applicable - Variance is not associated with potable water
.
6)
It is not anticipated that any adverse environmental impacts will be
produced by the granting of this variance
. The same effluent is
discharged to the Mississippi River 4,700 feet downstream of the 009
location, and no businesses or residences are located within this
distance .
7)
Compliance with the act will cause a hardship by requiring the City to rent
extremely large pumps and discharge piping which will pump the plant
effluent of 8 to 15 MGD from the Discharge 009 structure to a manhole
downstream of the maintenance location . These pumps will require
around-the-clock operators to man the pumps and be available should
problems occur
. Obtaining pumps and piping of this size would be
extremely difficult
8)
The proposed timetable for this maintenance operation is one week and
the discharge through 009 would be February 11-17, 2007 . After the
maintenance is completed, full compliance with NPDES Permit
IL0027464 will be met.
9)
Alternate methods of compliance would be to have the City perform
bypass pumping, which is deemed to be too costly . Likewise, the
Contractor could bid the bypass pumping, which would be even more
costly
. Another method would be to postpone the maintenance until the
flow in Wood River Creek was great enough to provide 5
:1 dilution and
the Mississippi River was above the 25 year flood elevation
.
Postponement could be long enough that the 42" welded steel pipe fails
on its own
. At that point, the City would be notifying the IEPA of an
Emergency Application and the plant will be discharging to Wood River
Creek at this location
. The final and most reasonable method is to apply
for a Provisional Variance .
10)
While it is anticipated that this variance will be necessary for one week
(February 11-17), the variance request is for 30 days (January 30 -
February 28)
. In case any unusual circumstances arise
. The work will be
completed as quickly as possible
.
11)
We have not requested and therefore have not been granted any
provisional variances within the past calendar year (2006)
