Additional comments are as follows:

1. Rancho Seco was shut down for refueling, maintenance, inspections, and modifications during the month of June.

2. Maximum waste water flow rate was 10,000 gpm for 4.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> on June 15.

3. Waste water discharges amounted to 162.7 M gallons.

4. Maximum dissolved solids in waste water discharge was 3,549 lbs, per day which occurred during a retention basin release on June 18,

5. Flow through the sewage plant averaged 28,381 gpd for the month of June which is an overload of plant design.

6. High Total Coliform, suspended solids, and settleable matter in sewage plant effluent is attributed to high flow, appreciably in excess of design flow.
