Narrative
On 4/7/2014 the patrol pilot reported a possible leak at 15:21. On 4/7 at 16:45 a sinclair employee responded to the report and was unable to find the leak site. The employee did not smell anything unusual and found a small pond of water adjacent to the row and assumed this was the condition called in by the pilot. On 4/8/2014 at 10:25 two sinclair employees found a 6' x 6' stain on row and could smell petroleum. They reported it internally at 10:30 cst and the controll center shutdown the line at 10:31 cst. Emergency 1-call submitted and sinclair maintenance dispatched to scene. Maintenance crews arrived at 15:00 and began excavating site. Pinhole corrosion leak found at 17:05. Patch welded on leak location at 17:30. On 4/9/14 sinclair pressured the affected segment to 217 psi and proof tested the line for 4 hours. Pressure actually increased to 222 psi on the blocked in section. On morning of 4/10/14 sinclair re-started the line with personnel at leak location visually inspecting pipe & repair. The investigation revealed that a piece of steel pipe found under the pipe at the leak location could have been the apparent cause of the pinhole corrosion leak. The steel pipe may have shielded the pipe from cathodic protection and caused a localized corrosion cell at this location. 2741 cubic yards of contaminated soil removed from leak site.
