Re :
Provisional Variance From Limits on Daily Maximum
For Ammonia Nitrogen of NPDES Permit IL0020052
Dear Mr. Halm
:
The Illinois Environmental Protection Agency (Agency) has completed its technical
review of the attached provisional variance request submitted by the City of Plano (City)
on January 13, 2006 (Attachment A)
.
The City is in the process of improving its
wastewater treatment capabilities with respect to nitrification and phosphorus removal
. It
is requesting this provisional variance so that it can complete the necessary construction
to tie in new aeration tanks into the wastewater treatment system .
Background
The City of Plano owns and operates a wastewater treatment facility located at 1001
South Hale Street in Plano, Illinois. This treatment facility consists of an activated sludge
plant designed for 0.95 million gallons per day (MGD). design average flow and 1 .67
MGD design maximum flow. Treatment consists of automatic bar screening, aerated grit
removal, flow equalization, aeration, final clarification, chlorination and dechlorination
.
The facility discharges to Big Rock Creek, which is a tributary at the Fox River
.
The City is in the process of completing its 2004 Improvement Project (project) to
expand and improve the treatment plant capabilities relating to nitrification and
phosphorous removal. The project was permitted by the Agency in IEPA Permit No
.
2004-AB-0275
.
In order to complete the project the City must construct a new connection between the
existing aeration tanks and the new aeration tanks. While this construction is ongoing,
one of the three existing aeration tanks will be taken out of service and short-circuiting
may occur in one of the other remaining tanks. The one aeration tank will be out of
service for approximately 15 days. After the necessary construction is completed, the
existing aeration tank will immediately be brought back in service .
Relief Requested
The City requests a provisional variance from the permit limits contained in NPDES
permit IL0020052 for ammonia nitrogen (Attachment B) . This permit requires the City
to meet the following for ammonia nitrogen :
During the period of the requested provisional variance the city will not exceed 15 mg/I
ammonia nitrogen as a daily maximum
.
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 appear 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 .
The Agency hereby GRANTS the City of Plano a provisional variance from the daily
maximum permit limits for ammonia nitrogen of NPDES permit IL0020052, subject to
the following conditions
:

A. The provisional variance shall begin January 13, 2006, and end no later than
January 27, 2006, during which time the City can exceed the daily maximum
permit limits for ammonia nitrogen as specified in NPDES permit IL0020052
.
B. The City shall operate its system to produce the best effluent possible, and at no
time shall the City exceed a daily maximum of 15 mg/I for ammonia nitrogen
.
C. The City shall notify Roger Callaway of the Agency by telephone at 217/782-
9720 when the aeration tank is taken out of service and again when aeration tank
is brought back into service . Written confirmation of each notice shall be sent
within five day to the following address
:
Illinois Environmental Protection Agency
Bureau of Water- Water Pollution Control
Attention: Roger Callaway
1021 North Grand Avenue East, MC #19

D. 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 certification should take the following
form :

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

RE :
City of Plano, Illinois
2004 Wastewater Treatment Plant Improvements Project
Request for Provisional Variance
Dear Mr. Calloway :
The City of Plano is respectfully requesting a Provisional Variance in accordance with Title 35
:
Subtitle A: Chapter II: Part 180. The discussion below follows the "thirteen points" listed in Section
180.102 .
1)
The City ofPlano requests a provisional variance from NPDES permit IL0020052 : Ammonia
Nitrogen as N (November-February), monthly average 2.3 mg/l, and daily maximum of 4.7
mg/I. It is anticipated that daily maximum Ammonia Nitrogen as N will not exceed 15
mg/I during the period of the provisional variance,
2)
The2004Improvementsprojectiscurrentlyunderconstruction,IEPAPermitNo.2004-AB-
0275. The project was undertaken by the City to expand and improve the treatment
capabilities of the plant specifically related to nitrification, and phosphorous removal . Prior
to bringing the new aeration tanks on line, the mechanical contractor must saw cut an
opening to connect the existing aeration tanks and the new aeration tanks. To accomplish

this, one of the three existing aeration tanks must be taken out of service, reducing the
aeration capacity by 33% . The aeration tanks are currently configured in a 3 pass
arrangement. The last pass will be taken out of service, and we do not have provision for
directing influent flow to the middle pass . As a result, the second pass will be in use but
there will likely be short circuiting .
One aeration tank will be out of service for approximately 15 days, potentially resulting in a
discharge of ammonia greater than the NPDES permit limits .
The hydraulic retention time with one tank out of service, considering current, existing flow
conditions of approximately 600,000 gpd, is 12 .71 hours which is greater than the 8 hours
required per Title 35 : Subtitle C : Chapter Il: Part 370.1210 .
However, there may be times when flows are over 2 MGD and the retention time in the two
aerations tanks would be 3.81 hours which is less than the 8 hours required per Title 35
:
Subtitle C : Chapter Il: Part 370.1210 .
3)
See Above.
4)
Not applicable. -
5)
The ammonia discharge will have a short term affect on the receiving stream, the Cedar Dell
Golf Course Irrigation Pond, and the Big Rock Creek.
6)
If the variance were not granted, the City would not be able to make the necessary
connections to the existing aeration tanks and as a result would not be able to bring the new
aeration tanks on-line in a timely manner to facilitate the remainder of the construction
.
7)
After the necessary connection is made, the existing aeration tank will immediately be
brought back in service .
8)
Alternatives to the provisional variance were evaluated in the field with the plant
superintendent, the mechanical contractor, resident engineer and consulting engineer. The
connection to the existing tank, if delayed to a date later in the project, would require

The variance is requested for a period of 15 days, beginning January 11, 2006

10)
No other variances have been granted to the City this calendar year
.
11)
The City's NPDES permit is current.
