Since 1993, DuPont has been investigating and cleaning up the Kinston site under the supervision of the U.S. Environmental Protection Agency and the North Carolina Department of Environmental Quality (“DEQ”) pursuant to the Resource Conservation and Recovery Act Corrective Action program. The program requires DuPont to identify all potential areas of environmental concern (“AOCs”), assess the extent of containment at the identified AOCs and remediate the AOCs to comply with applicable regulatory standards. Effective March 20, 2008, UK entered into a lease termination agreement associated with conveyance of certain assets at the Kinston site to DuPont.
