All data is included in Appendix 4B, Storm Event Summary Data. 2) The Average Total ISS Pumpout for an event was determined by determining the average total hourly pumpout of all 3 pumps for the storm event. The total of the average of each of the three pumps does NOT necessarily equal the average total pumpout. 3) ISS Pump Station Construction - Down to 2 pumps operating at one time for most of event. 4) Due to limited capacity for 5/10/04 storm indicated under Note 3, the information provided for that storm was not included in the average.

The total of the three pumps does NOT necessarily equal the total pumpout since the max for each pump could have occurred at different times during the event. 3) ISS Pump Station Construction - Down to 2 pumps operating at one time for most of event 4) Due to limited capacity for 5/10/04 storm indicated under Note 3, the information provided for that storm was not included in the average TABLE 4C-2 MAXIMUM ISS PUMPOUT ANALYSIS TR_4-A.T4C cdr

Therefore, operator logs were searched for dates when flows were high (>200 MGD), i.e., dates on which diversions after primary treatment would be more likely to occur. The table above lists the dates on which diversions were confirmed. Flow estimates were then made by United Water Services on the basis of duration of the diversion and the diversion channel capacity. Thus, these volume estimates are gross. UWS has reported that no diversions have occurred after March 31, TABLE 4D-4 SHEET 3 OF 3 MMSD RECORD OF IN-PLANT DIVERSIONS: TR_4-A.T4D cdr
