Special Conditions

SPECIAL CONDITION 1. Flow shall be measured in units of Million Gallons per Day (MGD) and reported as a monthly average and a 

daily maximum on the monthly Discharge Monitoring Report. 

SPECIAL CONDITION 2. The pH shall be in the range 6.0 to 9.0. The monthly minimum and monthly maximum values shall be 

reported on the DMR form. 

SPECIAL CONDITION 3. Samples taken in compliance with the effluent monitoring requirements shall be taken at a point 

representative of the discharge, but prior to entry into the receiving stream. 

SPECIAL CONDITION 4. All samples for Total Residual Chlorine shall be analyzed by an applicable method contained in 40 CFR 136, 

equivalent in accuracy to low-level amperometric titration or other methods found in Standard Methods for Examination of Water and 

Wastewater, current edition. Any analytical variability of the method used shall be considered when determining the accuracy and 

precision of the results. 

SPECIAL CONDITION 5. Compliance with discharge limitations for Outfall 001 shall be determined by representative sampling of 

Outfall 002. Due to the configuration of the discharge bay, which is immediately upstream of the two open cycle diffusers, the effluent 

from the discharge bay flows into the two open cycle diffuser pipes which equally release the discharge into the Mississippi River. 

SPECIAL CONDITION 6. Nothing in this permit affects or abrogates the responsibilities or commitments of the Permittee herein as set 

forth in the agreement entered into by the Permittee in the consolidated cases of Izaak Walton League of America, et. al. v. 

Schlesinger, No. 2208-71 and People of the State of Illinois, et. al. v. United States Atomic Energy Commission, No. 2208-71 (U.S. 

District Court, District of Columbia). 

SPECIAL CONDITION 7. Discharge of wastewater from this facility must not alone or in combination with other sources cause the 

receiving stream to violate the following thermal limitations at the edge of the mixing zone: 

A. Maximum temperature rise above natural temperature must not exceed 5ΕF. 

B. Water temperature at representative locations in the main river shall not exceed the maximum limits in the following table during 

more than one (1) percent of the hours in the 12 month period ending with any month. Moreover, at no time shall the water 

temperature at such locations exceed the maximum limits in the following table by more than 3oF. (Main river temperatures are 

temperatures of those portions of the river essentially similar to and following the same thermal regime as the temperatures of the 

main flow of the river.)

Special Conditions

6. As deemed necessary according to the above data, daily determination of the cross-sectional average temperature at the 500 foot 

downstream cross-section in the river. 

Compliance with the thermal limitations of Special Condition 7 shall be demonstrated as follows: 

1. When river flow is 21,000 cfs or greater and the ambient river temperature is 5Ε F or more lower than the monthly limiting 

temperatures, the temperature monitoring curve1

 establishes that the permittee is in compliance for all power generation levels; 

2. When the river flow is less than 21,000 cfs and/or the ambient river temperature is within 5Ε F of the monthly limiting temperatures, 

the permittee shall demonstrate compliance using either: 

a. Plant load, river flow, ambient river temperature, and the temperature monitoring curve, or 

b. Field measurement2

 of the river cross-sectional average temperature taken 500 feet downstream of the diffusers. 

In the event that compliance monitoring shows that the permittee has exceeded the monthly limiting temperature, the number of hours 

of such exceedance shall be reported on the permittee=s Discharge Monitoring Report.

 When conditions such as ice formation render the Mississippi River inaccessible to marine activity, the Permittee may 

demonstrate compliance with the thermal limitations of Special Condition 7 by using the most recent field measurement data 

collected at a river flow equal to or less than the flow for which field measurement data cannot be collected. The most recent field 

measurement data shall be normalized to the power production level for the day when the river was inaccessible. 

SPECIAL CONDITION 8. There shall be no discharge of polychlorinated biphenyl compounds from any discharge. 

SPECIAL CONDITION 9. There shall be no discharge of complexed metal bearing wastestreams and associated rinses from chemical 

metal cleaning, unless this permit has been modified to include the new discharge. 

SPECIAL CONDITION 10. Demonstration for the Quad Cities Nuclear Power Station in accordance with Section 316(a) and 316(b) of 

the Clean Water Act was approved by IEPA by letter dated July 28, 1981 and by the Iowa Department of Environmental Quality (IDEQ) 

by letter dated May 18, 1981. Based on these conclusions the following actions by the permittee are required: 

A. The permittee shall monitor fish impingement once per week, year round. Each year's data shall be tabulated and compared to

historical fish impingement data for the same period with the results submitted to IEPA Compliance Assurance Section and Iowa 

Department of Natural Resources by July 28, each year.
