Narrative
4" hennessey pipeline spill incident report. On october 17, 2018 gspp initiated line fill on our 4" hennessey pipeline that runs from a truck injection station near hennessey oklahoma to an interconnect on the gspp 8" mainline near covington ok. Gspp personnel shutdown at 5pm. Flow was reinitiated at 8:00am on 10/18/18 to finish the line fill. On october 19, 2018, at 6:15 pm, we received a notification from orr construction that our 4 inch pipeline was leaking. The control room was notified and the pipeline pumps at our hennessey truck station were shut down. Field operations personnel were then called out to isolate the section of the line that was leaking and begin to assess the extent of the damage. The line was isolated within 1-hour of initial notification. A temporary clamp was installed over the leaking segment of pipe. Initial remediation efforts focused on extent of the contaminated water and soil and containment through use of temporary berms and installation of earthen dams. On october 20, 2018 soil and water remediation efforts commenced in earnest. Concurrently with remediation efforts, the damaged portion of the line was replaced. An inline inspection was conducted on the line to ensure that no additional damage occurred, and the line was re-hydro tested to establish maop. As of november 8, 2018 remediation efforts are ongoing and the pipeline has been returned to service. Great salt plains midstream is continuing to work with environmental engineers and the oklahoma corporation commission through the remediation process. It is estimated that 1,562 bbls have been lost and approximately 1,300 bbls have been recovered from the soil. 320 bbls have been recovered and returned to gspm pipelines. A careful review of the pipeline segment that has been placed we believe the leak is the result of an unreported line strike which had to of occurred between the time of the operational hydro test to verify line integrity and the introduction of crude oil into the pipeline. At this time we have been unable to prove who struck the pipeline and we will continue to investigate. We reviewed the one call activity for the area of the leak. All tickets were marked properly. We feel that the cga root cause is "excavation practices are not sufficient" due to the fact the line was struck without proper one call notification and post damage operator notification. Repair and remediation costs incurred at this time are still being accounted, but currently is less than $1mm. We expect to have full remediation efforts complete and full accounting of costs completed by november 30th.
