Narrative
On november 6, 2017 a small stain was identified on some gravel inside the tank dike adjacent to the buried common center suction/fill line of tank 673 at explorer pipeline's hammond, indiana tank farm. The tank is in fuel oil service. Hand excavation was conducted, and identified 2-quarts of product. Due to potential costs meeting or exceeding $50,000, the nrc was notified. The 48 hour nrc notification was number 1195835. Hydrovac excavation began to expose the buried common suction/fill line, and the tank shell valve. A total of fourteen 14 gallons of product have been identified, and recovered since november 6, 2017. The tank recently underwent an API 653 internal inspection in late 2016, and was completed in early 2017. The tank was internally coated in february 2017 following the API 653. Monthly breakout tank inspections did not identify any potential sources. The station piping is ansi class 150. The pressure indicated in the report at the time of discover is 137.5 psi, which is station meter pressure. The highest station meter pressure the previous 30 days was 238.8 psi on october 11, 2017. The common suction and fill line and the tank shell valve was visually inspected and monitored. The suction and fill line additionally underwent a ut inspection, as well as the valve underwent additional inspections. The tank, excavated common suction and fill line, and valve continued to be monitored. During the investigation explorer was informed that a third-party contractor potentially spilled product in the location of the stain when refueling equipment and failed to report. However, this potential refueling event couldn't be substantiated. The source of the stain couldn't be identified, and no additional product or staining was discovered. Monitoring wells were installed around the buried common suction and fill line and the valve, but no product has been identified. The area of the release was inspected during a standard PHMSA field inspection on june 18, 2018. Explorer indicated it was closing the report, but it will continue to monitor.
