Corrective Actions

December 21, 2023

A board-approved remediation contractor cleaned the portable using a High Efficiency Particulate Air (HEPA) vacuum. After the initial vacuuming was completed, each surface was wiped with a cleaning agent/disinfectant. The surfaces were once again HEPA vacuumed after residue from wiping had dried. The remediation contractor also placed two HEPA air purifiers to operate overnight to reduce suspected particulate from the discharge event/cleaning activities.

The Office of the Environment arrived onsite prior to the contractor to verify that areas had been cleaned. The Office of the Environment requested that the remediation contractor re-clean a few areas and observed the remediation contractor clean the requested areas.
