Narrative
Personnel of the marathon galveston bay refinery discovered a pinhole on the 10" above grade relief line and informed magellan representatives. The line was isolated and the leak was repaired by magellan's contractor. The section of pipe where the release occurred was removed. The cutout and the remainder of the line were inspected for additional internal corrosion features with none found. A new piece of pipe was installed where the cutout was made and the line was returned to service. Impacted soil was remediated. The crude product in the piping system is treated with corrosion inhibitor and monitored with internal corrosion coupons. However, the low/intermittent flow in the facility relief piping and inability to flush the line due to the type of relief valve installed likely allowed bs&w in the crude to settle out resulting in internal corrosion. A project has been executed to replace the relief valve and remaining pipe on the relief line which will allow the line to be flushed during relief valve inspections. Note: the national response center was notified when it became apparent that total costs attributed to the detection, emergency response, repair and clean-up of the release would meet or exceed the $50,000 reporting threshold in 49 cfr part 195.52(a)(3), and for no other reason.
