Narrative
On august 13, 2015 at approximately 11:00am, a contract crew backfilling the l2 station discharge valve struck a 3/4 inch valve attached to the top of line 2. The onsite contract inspector immediately notified the control center and the line was shut down. Local personnel were notified immediately and containment and clean-up activities commenced. The outlet valve to the sub-surface manifold yard drain oil/water separator was closed immediately following the release. Free product was collected from hand-dug recovery pits and hand augured wells. Groundwater was impacted, but there were no impacts to surface water or the facility pond. Impacted soil was transported to soilworks, inc. Located in selma, nc for disposal. Recovered product/water was taken to heritage-crystal clean (formerly fcc) located in concord, nc for treatment and recycling/disposal. Contaminated sorbents were drummed and shipped via zebra environmental , high point, nc for treatment and disposal to uwharrie regional landfill located in mount gilead, nc. Repairs to the pipeline commenced immediately following the release. The 3/4 threaded hole was plugged and a 3 inch weldolet and weld cap were welded over the top. A call was placed to nrc on 8-13-15 based on the fact that the estimated cost of the incident would likely exceed $50,000. Since the spill impacted groundwater, the north carolina denr was notified at 12:00. A notification of discharge form was also submitted to nc denr mooresville office on august 13th, 2015 via email. Approximately 4950 gallons of free product was recovered using vac trucks and sorbent material. Recovered material was transported to heritage-crystal clean in charlotte, nc for treatment and disposal. Approximately 449 tons of impacted soil was removed. Based on product in soil calculations the soil was estimated to contain an additional 875 gallons of product bringing the total product recovered to 5825 gallons. An estimated 20 tons of additional impacted soil could not be removed without undermining part of the manifold area infrastructure. Based on product in soil calculations an additional 40 gallons remains in those areas. An air sparge / soil vapor extraction system approved by ncdeq has been installed to address remaining soil and water impacts. The total release estimate is 5865 gallons.
