Special Conditions

1. The pH shall be in the range of 6.0 to 9.0.

2. 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 waters.

3. Continuous monitoring throughout a representative chlorination period shall be performed once per week above the second drop structure in the discharge flume during the respective chlorination period allowing for lag time between the initiation of chlorination and the point of sampling. If continuous monitoring cannot be perfomed, grab samples shall be taken in the discharge flume at five minute intervals or less during the respective chlorination period to develop a chlorine concentration curve allowing for lag time between the initiation of chlorination and the point of sampling before the first grab sample is taken. The individual values and average (mean) values for each set of grab samples shall be reported including the time samples were collected, the time and duration of the chlorine dosing period plus the amount (lbs/ day) of chlorine applied. For continuous monitoring data, the time of sampling, the time-and duration of the chlorine dosing period plus the amount (1bs/ day) of chlorine applied shall be reported.

4. Discharges to Lake Clinton shall not exceed an effluent temperature of. 960F, except that'during such time as only one generating unit is in operation at the Clinton Nuclear Power Station, the daily average discharge temperature shall not exceed 990F during more than 12 percent of the hours in twelve-month periods ending with any month and shall at no time exceed 108.30F.

(a) Compliance with the water temperature monitoring requirements shall be detemined by reporting the daily average and daily maximum water temperature of the discharge. The number of hours the discharge temperature exceeds 99.00F during each month shall also be reported.

5. The daily maximum fecal coliform count measured once per week shall not exceed 400/100 ml.

6. The intake structure shall be operated and maintained in a professional manner so as to minimize the possible adverse impact on water quality which might result from the discharge of any collected debris or fish. So as to minimize possible adverse impacts, for purposes of this permit, the intake structure operation and maintenance shall include, but not be limited to, the following:
