Narrative
Stainless steel thermal relief tubing installed around a check valve on tank 2700's tank line developed a crack resulting in a release of approximately 1 barrel of gasoline. It was determined that fatigue failure of the thermal relief tubing occurred due to lack of adequate support to counter vibration. Replacement tubing was installed with sufficient supports to counter the impact of excessive vibration. This project has been closed out with the idnr and within magellan so no future costs or activities will take place. Approximately 31 cubic yards of impacted soil was remediated through excavation and proper disposal. Supplemental/final filed: updated part a11(volume recovered), part d 8d(emergency response cost), and 8e (environmental remediation cost) and part h (narrative)
