Office of Environment directed the HCPSS Project Manager and roofing contractor of the materials impacted and how to dry those not needing to be discarded. The roofing contractor had their own drying equipment. Dehumidifiers and carpet blowers were utilized to dry impacted materials. Holes were made within impacted drywall to force air into the drywall cavity. The equipment was to run until the Office of Environment reassessed the impacted materials .
On September 8, 2020, the Office of Environment determined impacted materials were dry and equipment could be removed.
