Spill Description:
On 1/8/2025, Sian E27-6 flowline decommissioning activities were completed. During the completion of the activities, no potential presence of impacted material(s) was observed/smelled. Consistent with Rule 912, samples were collected and analyzed to determine whether any constituents are present at levels in excess of Table 915-1 standards. Final laboratory analytical results received on 2/28/2025 indicate that soil sample FL01-15, discovered along the flowline, exceeded ECMC Table 915 standards for benzo(a)anthracene at 0.0176 mg/kg. Groundwater was not encountered during decommissioning activities.
