Narrative
On 7/16/19 at 1030 hours, employees and contractors at mipc were walking down the work scope for a project involving the aboveground storage tanks at mipc's chelsea tank farm. During the walk down an employee observed an odor around the base of tank 711. There was no product visible on the ground. Tank 711 was safely emptied and taken out of service in preparation for an API std 653 out-of-service inspection on august 28, 2019. The API inspection report received on september 17, 2019, found that tank 711 had four (4) product stains from the bottom welds. Those four (4) stains were vacuum box leak tested and only one (1) stain leaked and was at the bottom to shell weld. Tank 711 remains out of service until a permanent repair is made. Updated the report to include a cost estimate for repairing tank 711 that's budgeted for 2022. The accident report will be updated after final costs are determined.
