Narrative
April 4, 2013 2:45 pm: empco operations personnel at swt area I discovered a valve vault within the facility associated with the wc54 white products pipeline was partially filled with diesel and water.� the estimated volume of this diesel/water mixture is 1.3 bbls. The valve vault (8' x 5.5'x 3.11) contains two valves (valve #5 and valve #6) and some piping associated with the scraper trap for the pipeline.� the walls of the vault are steel however the bottom of the vault is dirt. At the time of discovery, the source of the leak was not evident. Following investigation: apparent cause: valve packing failure. The motor operated headgate valve was observed to have product weeping from the base of the stem and into the valve vault. The initial sample was taken and observed to be diesel which was verified by gravity and flash point. After repairing the valve, a stand up pressure test was performed on the station and pipeline side of the valve, results passed and were positively endorsed upline
