Permitting
Northrop Grumman has RCRA Part B permits for hazardous waste storage (not official copy of permit), and post-closure care (not official copy of permit). In addition, Northrop Grumman has interim status for treatment of on-site and off-site generated reactive hazardous waste. Northrop Grumman has submitted an open burning permit application. In the fall of 2005, the Division instructed Northrop Grumman to move forward and conduct a risk assessment of their open burning activities. This is a critical step in determining permit conditions. Northrop Grumman obtained permission to conduct air emission testing at the Dugway Proving Ground ODOB in the summer of 2006 and has been working since that time on completing the risk assessment.
Corrective Action
Northrop Grumman is conducting a RCRA Facility Investigation. The Phase I investigation has been performed and Northrop Grumman has submitted a report of the effort that is currently under review by the Division.
