Narrative
On 5/12/19 at approximately 19:30, oil was discovered flowing into the tank containment from the roof drain pipe. Roof drain valve was blocked in to stop the release. The release was fully contained within the diked area and all free product was recovered and contaminated soil removed for on-site remediation. Upon examination an area of external corrosion pinholes were found were found on the roof. The holes allowed water to enter the pontoons, which resulted in the slight sinking of the roof on that side. Once the roof began to sink, it allowed oil to enter the pontoons and fill them. As the pontoon filled, the oil pushed up through the original holes that let the water enter. As the oil pushed out of the holes, it found its way to the roof drain and that allowed the oil to exit the roof drain. The roof has since been cleaned and the holes have been patched. A permanent repair to roof is being developed.
