| On May 24, 2017, TEP production personnel noticed wet soils on the pad surface near a dump line adjacent to the separators. The dump line was pressure tested on the same day, and the line held pressure. Personnel then tested a segment of the produced water main line that passes through this same area. While pressure testing this segment of water line, produced water was observed bubbling to the surface of the pad at several locations, and pressure in the line could not be maintained. Wells were shut in, utility locates were conducted, and an excavation contractor is excavating and repairing the line today (05/25/17). Field screening equipment and soil samples will be used to determine vertical and lateral extent of contamination, and to ensure that COGCC 910-1 cleanup standards have been met. The release appears to be contained completely on-location. There are no off-site or other environmental impacts associated with this release. |
