Narrative
Control center recognized a line balance variation and calculation around 21:12 on 4/23/2014. After the technician arrived on site at 22:50 it was confirmed that the discharge stainless steel 3/8 inch tubing of the pd pump at the station had failed. The station was isolated from the c15 line and tubing was replaced and station put back into service 4/24/14 10:30. Excessive vibration on this 3/8 inch tubing resulted in the tubing leak. Previous support had been excavated around the area during a remediation and clean-up of previous soil contamination. Tubing was replaced with stainless steel braided hose to absorb and eliminate direct vibration.
