| On 07/02/2025, CACHE-66N63W 17NENW tank battery 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 07/16/2025, indicate that soil sample, AST01, discovered beneath the above ground storage tank, exceeded ECMC Table 915 standards for TPH-DRO at 1750 mg/kg, and TPH-ORO at 2980 mg/kg. Groundwater was not encountered during decommissioning activities. This location is within 300 feet of water of the state. |
