SPECI AL C0#0!T104 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.

SPECIAL CON 0!T!DN 3. Continuous monitoring throughout a representative chlorination period shall J i

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 performed grab samples shall be taken .

in the discharge flume at five minute intervals or less during the respective chlorinetton period i to develop a chlorine concentration curve allowing for lag time between the initiation of ehlorination 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 dostng period plus the amount (1bs/ day) of chlorine applied. for continuous chlorine monitoring, analytical data from only one representative penitoring period each week need be reported on the monthly discharge monitoring j report. For continuous monitoring, the chlorine concentration curve. the time of templing, the time and duration of the chlorine dosing period plus the amount (1bs/ day) of chlorine applied shall be reported.

SPECIAL CONDITION 4. Discharges to Lake Clinton shall not exceed an effluent temperature of 960F except that during such Line as only one generating unit is in operation at the Clinton Nuclear Power Station, the daily average discharge temperature shall not exceed 99 F 8 during more than 12 percent of the hours in twelve-month periods ending with any month and shall at no time exceed 108.30F.

1 (a) Cone 11ance with the water temperature monitoring requirunents shall be determined by )

, (b) During the ef fective perted of PCB Order 89-213 the temperature at the second drop structure of the discharge flume shall be limited to a daily average temperature not l exceeding 99* F during more than 90 days per year running from January 1st through December 31 and at r.o time shall the temperature of the discharge exceed 110.7* F. ,

SPECIAL CON 0!T!DN 5. The ntake 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.
