temperatures, the temperature monitoring curve 1 establishes that the permittee is in co mpliance for all power generation levels;

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

the permittee shall demonstrate compliance using either:

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

b. Field measurement 2 of the river cross-sectional average temperat ure taken 500 feet downstream of the diffusers.

In the event that compliance monitoring shows that the permittee has exceeded the monthly limitin g temperature, the number of h ours

of such exceedance shall be reported on the permittee

= s Discharge Monitoring Report.

1 The temperature monitoring curve identified as figure 2 in t he December 2000 "Revised Temperature Monitoring Curve for Quad

Cities Nuclear Generating Station".

2 When conditions such as ice formation render the Mississipp i 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 producti on level for the day when the river was inaccessible.

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

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