(Degrees F)Maximum Actual Blowdown Temp.(Degrees F)120 120 120 120 85.4 80.9 76.7 77.6 Note: Station procedures derive the Calculaed Manumm Allowable Blowdown Temperature based on existing Rock River temperature and a calculated maximum river temperature increase.

When the arithmetic sum of these values exceeds 120 degrees Fahrenheit.

the Calculated Maximum Allowable Temperature limit defaults to 120 degrees Fahrenheit.

This report covers the period of December 1, 2009 through December 31, 2009.Special Condition 5 of the NPDES permit requires the station to weigh the copper anodes at the end of the zebra mussel control season and to Include the total mass of copper used in the discharge monitoring report. The zebra mussel copper ion skids were shutdown on December 2, 2009. The anodes of the OA copper Ion skid were removed and weighed on January 8, 2010. The anodes of the OB copper ion skid were removed and weighed on January 8, 2010. The total mass of copper used for zebra mussel control was 214 pounds.If there are any questions regarding this report, please contact Mr. Stanley Kerr, Chemistry Manager, at (815) 406-3200.Respectfully, Da Zel .Enih Site President Byron Nuclear Generating Station DJE/ZC/sdk Attachments NATIOA POUATANT DISC*ARE ELMINATION SYSTEM (NVES)OMNM MOIToW0'm RUEPORT PEinEE NAM SSDDt NAME E~m Qsnrtaln Co..
