Narrative
On july 15th 2019 at approximately 7:23 pm, we received a phone call from an individual reporting a spill. This person called the phone number on the pipeline marker. We dispatched personnel to the area and confirmed the leak at approximately 8:45pm. The first valve was closed at 9:00 pm and then the second and final valve was closed at 9:30pm. The area was deemed safe and we contacted our third party clean up crew to come out the following morning to initiate clean up. The next morning the emergency one call was initiated prior to digging. By 10:30am the one call's were cleared and clean up began. This appears to be a pin hole leak on a previously out of service pipeline, so some details requested in this report are not known. We are land-farming the remaining oil under the direction of the wydeq, and these efforts will continue for some time. After discussing with PHMSA's aid team, it was decided that we can count the oil which is being land-farmed under the direction of the wydeq as recovered (part a). Part e questions 2, 3 and 5f: established mop unknown, thus making the determination of exceeding mop and % of smys unknown. The 950 mop number in part e is based on the set point of the relief valve after discussing with PHMSA's aid team.
