Spill Description:
On 07/23/2025, Aloysius C34-22D Tank Battery resampling 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 08/18/2025, indicate that soil sample, SB03, discovered at the former aboveground storage tank, exceeded ECMC Table 915 standards for naphthalene at 0.0332 mg/kg. Groundwater was not encountered during resampling activities. All data collected will be submitted with the next quarterly Supplemental Form 27 for REM 34764, due by 10/13/2025.
