| On 2/24/2025, the potential presence of impacted material(s) was identified via hydrocarbon odor and hydrocarbon staining during decommissioning activities at the Klausner 1, Tank Battery, samples: GS01. The volume of potentially impacted material(s) is not currently known. Partial laboratory data indicated a historical release occurred at the Klausner 1 along the sales line during tank battery decommissioning. One soil sample, GS01, exceeded ECMC standards for ethylbenzene at 0.0085 mg/kg, 1,2,4-trimethylbenzene at 0.11 mg/kg, 1,3,5-trimethylbenzene at 0.046 mg/kg, and TPH at 6308.4 mg/kg. Groundwater was not encountered during decommissioning activities. Final analytical results from initial soil sampling will be included on a Supplemental Form 19. |
