Narrative
On 9/25 at approximately 1845, operations personnel discovered crude oil spraying from a cracked weld on discharge piping associated with pump p122. The pump was shutdown and isolated, agency notifications were performed and an erl call was conducted. Product sprayed around the adjacent area, ran approximately 162 feet down the roadway and then entered engineered containment (the slough). At the time of the release, the slough was being used to temporarily store approximately 70,000 bbls of hydrostatic testing water which will need to be treated. The estimated release volume was 19.6 barrels and the cleanup and repairs have been completed. Metallurgical analysis found the fractured girth weld was caused by a fatigue fracture initiating at a poor repair weld. Pump coupling failure provided a source of cyclic stresses for fatigue crack propagation in the repair weld on the reducer side. Note: part c, #3, weld, the failed weld repair was located on the flange to reducer weld. Note: part d, #5, while no surface or groundwater was impacted, some of the crude oil escaped to our secondary containment area (called the slough) which, at the time of the release, contained approximately 70,000 bbls of hydrotestic testing water which may need to be treated to meet discharge requirements. Note: part g5, #3. Specify ' the flange to reducer weld was repaired some unknown time after the original 1998 installation by the previous owners of the carson facility. Note: part g5, #7, unknown if previous owners conducted additional hydrotest(s) since original construction at the point of the accident.
