Narrative
Tank 906 at lockport terminal was taken out of service for API 653 inspection. During the inspection, a through-wall corrosion pit was discovered. An approximate 12'x 12' square hole was cut in the tank bottom, and samples were taken from the soil/water between the tank bottom and underlying clay liner. Based upon sampling results, the estimated release volume is approximately 25 gallons. Remnants of abrasive material, or other contaminants, found under the coating affected its adhesion, which could have hastened the delamination and premature failure. 06/04/2018 - updated cost estimates, updated volume based on soil sampling results. 5/3/19 - updated part g, #7 by selecting water drop out, updated #8 by selecting metallurgical analysis, and updated the narrative with failure mechanism information.
