One of the field technicians opened a valve on the back of a super sucker truck to connect a hose when the load starting spilling out of the valve. The technician tried to close the valve but could not get it closed completely as a rock prevented full closure of the valve. This allowed the contents of the truck to spill out onto the well pad. In order to stop any further further spillage, the field technician switched the truck onto vacuum to prevent any further loss of material out onto the well pad. The entire release was contained to a small area on the pad surface. Service company personnel were able to recover a majority of the material spilled as noted above. No surface water or groundwater was impacted by the spill.Service company personnel utilized their super sucker trucks to vacuum off the top 3-4 inches of the pad. The bottom of the excavation was field screened and yielded results be low the COGCC Table 910-1 standards of 500 ppm TPH in soil. A confirmation sample was collected and has been submitted to an accredited laboratory for the full Table 910-1 analytical suite. Further remedial actions, if warranted, will be based on these results. 0 0 0 0 0 0 0 0 0 0 2604 false false 3 1 false false false false false false true false false true true false 35 25 pit bottom sludge 3 400913701 1 2015-10-08T00:00:00-06:00 true false false false Service company personnel were recovering pit bottoms on the location.
