Energy Transfer Pipeline Edmond Spill 2023


On September 25, 2023, at approximately 12:18 p.m., the National Response Center received a report of a 150-barrel (bbl) crude oil spill from a pipeline onto soil. The U.S. Environmental Protection Agency (EPA) deployed an EPA On-scene Coordinator (OSC) and its Superfund Technical Assessment and Response Team (START) contractor to the site at approximately 4:00 p.m. The EPA, local fire department, Oklahoma Water Resources Board, and emergency response crews from the Pipeline and Hazardous Materials Safety Administration responded to the spill. Energy Transfer, the responsible party (RP), reported that a 16-inch pipeline carrying sweet crude had been struck with an excavator by the land developer’s sub-contractor.

The spill was reported to the RP around 10:50 a.m. The RPs’ emergency response sub-contractor was on-site by 12:00 p.m. to begin the cleanup. The pipeline was not actively pumping crude at the time of the puncture but was under pressure. The pipeline punctured runs from Cushing, Oklahoma, to three possible locations. At the time of the break, the pipeline was lined out to the Texas Gulf Coast. The damaged line was repaired by using a leak repair clamp, which was secured around 1:00 a.m. As of September 26, at 11:00 a.m., Energy Transfer reported they had recovered approximately 2,400 bbl of oil. Stained soil and minor oil will be collected under the oversight of the Oklahoma Corporation Commission (OCC). Since the afternoon of September 26, there is no threat to navigable water remaining. 

Air Monitoring

EPA conducted handheld air monitoring for total volatile organic compounds (VOCs) and benzene September 25-26.

The site-specific air monitoring procedure was to measure total VOC using a MultiRAE monitor. If the sustained VOC level was above 1 part per million (ppm), another monitoring tool called an UltraRAE was used to measure the specific chemical benzene. VOCs above 1ppm were detected at five locations of the 43 monitored. One of those elevated VOC detections was observed in the adjacent neighborhood, and the benzene level for that detection was 0.03 ppm. The remaining four elevated VOC readings were immediately adjacent to the spill recovery location.
