Additional comments are as follows:

1. Rancho Seco returned to operation November 2, after being shutdown in October due to Feedwater Pump Control problems.

The unit was slowly raised to ~90% and has been holding at this power level since November 21.

2. Maximum waste water flow rate was 10,000 gpm for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> on November ll.

3. Waste water discharges amounted to 265.6 M gallons.

4. Maximum TDS in waste water discharge was 510 ppm based on conduc-tivity, which occurred during a retention basin release on November 19.

5. Flow through the sewage plant averaged 9,034 gpd for the month of November, which is an overload of plant design. I

6. High Settleable and Suspended Matter in sewage plant effluent can be attributed to flow in excess of design. The new overland sewage plant was put into operation November 30.

7. High chlorine in the plant effluent and site boundary was due to a malfunction of the sewage treatment plant chlorination system.

This system was temporarily shutdown. CRWQCB informed of violation on November 29 by telephone.
