Narrative
05/20/2019, 11:24-hours, hiland crude contracted aerial patrol observed a possible leak and reported the observation to local operations; 11:25-hours, operations dispatched staff to investigate. Upon arrival at the site at approximately 11:30-hours, staff identified a leak which was occurring from a pin hole in a 2-inch elbow in the drain pipe of the pig trap. At 11:35-hours, valves either side of the leak within the 2-inch drain pipe were closed to terminate the leak and the spill was contained. At 12:46-hours, the operations supervisor was on site to assess the situation and confirmed discovery of an estimated 22 barrels of spill quantity. There were no pipeline interruptions to customers nor throughput based on this isolation of the 2-inch drain pipe. With the pin-hole leak located in the 2-inch drain pipe, it was not necessary to shut-in the pipeline. Spill cleanup and disposal began promptly. The spill was recovered with a recovery volume of 22 barrels as estimated. As part of this investigation, operations estimated the leak began 05/15/2019, reaching five gallons qunatity at 19:45 hours. The pipeline routinely operates between 50 psig and 100 psig. The 2-inch elbow was removed and delivered to a laboratory for metallurgical analysis. Spill remediation was completed 7/09/2019. Field repair of the piping was completed 7/19/2019. Argen laboratories, houston, texas provided analysis for kinder morgan metallurgy staff. The pinhole leak in the 2-inch elbow was located in the 6:00 position; said elbow was part of the pig trap drain line pipe. The 2-inch elbow was stamped with the following: 2 std wpb mak 1 11 96. Said elbow was installed in 1995 but the manufacturer, grade, and coating are unknown. The pinhole leak was the results of corrosion involving chlorination and sulfidation reactions. Metallographic evaluation did not reveal injurious microstructural features. The chemical analysis results of the 2-inch elbow were consistent with astm a234 grade b.
