On august 14, 2021 internal corrosion caused a pinhole leak on cox's 6" HL pipeline segment #3495. Operators noticed the the oil tank level had not increased and the pipeline was in production. They had all production shut in and closed the valves on both ends of the pipeline. A helicopter was then utilized to determine that there was a spill in the marsh about 4 miles from the station. The operator then contact the nrc to complete a notification and contacted forefront cox's osro. At 1057 hours: louisiana state police hazmat; mrs.

Two additional nrc notifications were made report #1313688 and #1313827 (48-PHMSA update). Based on evaporation modeling, forefront expected 84% of the released 283.8 bbls of condensate (238.392 bbl) to naturally evaporate leaving 45.408 bbls that was recovered by absorbents and from the in situ burn. To repair the line cox operating had certified split-sleeve clamp (sn-6193401) installed on the pipeline.
