Yes, all liquid and sediment has been removed from the Lined Pond to increase freeboard volume and the liner has been inspected.
Further, as detailed in a letter dated December 8, 2011 to the NCDENR Division of Water Quality, Hexion intends to continue to hold
the Lined Pond out of service to further assess their ability to safely and effectively operate in this manner. If Hexion determines
that the Lined Pond can be permanently removed from closed-loop recycle service, we will submit a permit modification request at
that time.
