Narrative
On 9/16/2019, at 13:50 the control center received a call from resident reporting dead spots in the grass, with dark spots in the soil and an odor of diesel. The resident described his location as south of bb highway in clark county. The control center contacted local operations personnel as a precaution, before personnel could reach the site, the control center initiated a line shut down at 14:02. The three intermediate motor operated remote valves were blocked in between gibbs station and montrose terminal. The maintenance crew was dispatched to the site. A crew with a mini excavator was at the scene within 2 hours (15:45). The pipe was exposed and gasoline saturated soil was observed near the pipe. Excavation continued until the leak location was found. A small corrosion pit was found at the 5 o'clock position. Initially observed as just a seeping leak, when the rust scale was removed from the pipe so that a repair clamp could be installed, the leak rate increased. A clamp was successfully installed at 16:45 and the emergency phase of the incident was over. There were no personal injuries or fires related to the release or response. Only soil impact was observed. No surface water was impacted. No free standing liquid was observed ' only saturated soil. The site is being excavated of all contaminated soil. Once all contaminated soil is removed, the pipe will be cut out and sent to a laboratory off site to determine pipe grade and seam type.
