Narrative
A gasket failed on a low pressure strainer on the #3 north manifold in the magellan west tulsa pump station and terminal facility. The strainer was upstream of the main line pump on the low pressure manifold. The strainer was removed and a spool of pre-tested piping was installed in its place. The failed gasket and strainer were sent to a laboratory for failure analysis which determined the strainer top closer and strainer flange exhibit a warped topography. The report concluded that the cap was likely removed and reinstalled in a different orientation resulting in the creation of non-uniform gaps around the top closer and strainer flange mating surfaces. Consequently the gasket failed at the locations of maximum gaps between the cap and the flange. This was not an installation failure has the warped topography was unknown prior to performing the failure analysis and no specific orientation is required of the strainer top closer. The release volume has been revised from 50 barrels to 36.5 barrels with 31.5 barrels recovered. Due to the piping configuration in the area, the soil could not safely be remediated further. Samples of the remaining soil were with oklahoma corporation commission cleanup standards. As a final remediation step, the area was treated with a microbial hydrocarbon remediation product. Approximately 150 cubic yards of impacted soil was mitigated in the remediation effort.
