The site was "closed" in 2002 with a Deed Notification (also known as a Notice of Contamination to Property) requiring the asphalt parking lot to be maintained and utilized as a barrier cap for the contamination. At the time closure was granted for this site it was not anticipated that excavation would be required as part of this facility's renovation and expansion. In addition, the contamination appeared to relatively low level and limited in its extent. Unfortunately, the contamination proved to be more significant than thought.
