Mr. Dolan introduced Mr. James Kelly, Plant Operations Division Manager, and Mr. John Pearl, Plant Maintenance Division Manager, who gave a full report to the Board on the incident. Mr. Kelly stated that on Thursday, February 12, 1998, at 7:01 p.m. the first alarm from the Orinda Crossroads Pumping Station was received. The on-call Pumping Stations Operator was deployed immediately and arrived at the site at approximately 7:30 p.m. The Pumping Stations Operator found the upper stage volute of the 3,000 gpm electrical pump had broken in half. This failure mode allowed the lower stage pump to continue to pump dilute raw sewage, which filled the dry well to a 10-foot depth. Upon arrival, the Pumping Stations Operator immediately turned off the pump. At this time, both diesel motor driven pumps were under three feet of water, and the motors for both lower stage 'do�__ I INSTALL MOTORIZED GRINDERS AT MORAGA PS Issues: _y 1 .
