I. Discharge Points Covered in this Report Discharge Point Discharge Identification 001 Condenser and Service Cooling Water 001A Radwaste System Effluents 001B Non-Radioactive Makeup System and Demineralizer Effluents 002 Condenser Backwash and Slime Control 003A Intake Screen Wash

! II. Summary and Notes of Discharge Report A. The pH for Intake Screen Wash (Discharge Point 003A) and the Condenser Backwash (Discharge Point 002 1) was not measured.

B. The Total Residual Chlorine for Condenser Backwash, Discharge Point 002 1, was not measured.

C. The flow point 001 is calcualted from system pump capacity and is equal to the total flow for all pumps in the system running at full capacity for a 24-hour period. The flow at point 001A is metered and the volume for each discharge is recorded. The flow at point 001B is measured by noting sump levels before and after discharge. Flow at point 002 is a conservative figure obtained by calculating flow if backwashing took place for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
