Narrative
Local operations personnel observed a small stain on the gravel near tank 306. Operations control was notified and investigative event procedures were implemented. Free product was collected and interceptor trenches were excavated. Observance of continued product accumulation identified the release originated from tank 306. Product was transferred out of the tank, the tank was cleaned, and inspected. The release originated from a pinhole in the fillet weld where the sump joins the tank bottom. The pinhole contained weld slag which was possibly dislodged during installation of a new internal floor lining in 2015. The tank is currently out of service with repairs anticipated to begin before the end of may. Out of service inspection procedures will be changed to include magnetic particle examination of all tank bottom sump welds in addition to visual inspection.
