Narrative
On september 3, 2020 at 14:30, 2.1 barrels of product was discovered near the e-valve of tank 150-65. The product was cleaned up immediately. The source of the leak was identified as a buried flange near the e-valve. The bolts on the flange were torqued and the leak stopped. The incident investigation showed the likely cause of the loose bolts was due to thermal pressure. The line has pressure relief valve. Tank 150-65 was out of service for API 653 and returned to service in march 2020. The thermal for the tank-lines were routed to tank 150-66. The thermal line that leaked was not rerouted to 150-65 until 18 september 2020 (13 days after incident). The gasket was replaced out of an abundance of caution. Plan for prevention: the flange will remain exposed and not reburied. On a go forward basis, the thermal relief system will be reviewed as the tanks is returned to service using the manway removal form.
