Narrative
On august 1, 2025, at approximately 9:04 a.M. Cdt, technicians arrived at throckmorton station to perform scheduled pigging activities. Upon arrival, they discovered a leak originating from mainline pumping unit #2. The technicians immediately notified the qualified individual (qi), who in turn contacted the artesia control center. The pipeline was shut down by stopping all mainline pumping units and closing all associated motor operated valves (movs) on the system. While the shutdown was in progress, technicians observed product beginning to flow outside the station boundaries and onto the pipeline right-of-way. Using shovels, they quickly constructed an earthen berm to prevent further migration of product. Once the pipeline was fully isolated, the technicians blocked out both pumping units and placed collection buckets under the release point to capture residual flow. These efforts were slowed due to hazardous vapors, requiring the use of air monitoring equipment to continue safely with lockout/tagout procedures. Remediation activities began immediately, aided by a vacuum truck already onsite for the planned pigging operations. After unit #2 was fully locked and tagged out, technicians identified the failure as a 1/2-inch stainless steel tubing line on the suction side of the pump, which had cracked approximately one inch from the tubing ferrule. The failed section was removed and replaced with new stainless tubing. Blackland services, a local contractor, arrived shortly thereafter with additional personnel and equipment to support cleanup. In addition, holly energy�s spill response trailer was mobilized from abilene, bringing absorbent pads, boom, straw waddles, and supplemental air monitoring equipment. The initial quantity reported was 155 barrels of gasoline, but this was later corrected to 75 barrels of jet fuel. Free product was captured by the vacuum truck, while contaminated soil was excavated and staged on plastic tarps pending removal. The pipeline was returned to service at 14:13 cdt on august 1, 2025, with unit #2 remaining locked and tagged out. Remediation efforts continued through the weekend, and the entire volume released was recovered. The failed tubing section was sent to a laboratory for metallurgical analysis, coordinated through a local swagelok representative. Results are pending. Based on the findings, holly energy will implement configuration changes and/or further investigation into contributing factors to prevent recurrence.
