Security clearance · Secret level
The L clearance is the Department of Energy equivalent of a Secret clearance. It grants access to Confidential Restricted Data, Secret National Security Information, and Confidential Formerly Restricted Data. L clearances are used for personnel who need limited access to classified information in the DOE complex.
L clearances are required for many support contracts at DOE facilities, national laboratories, and nuclear sites. Positions in facilities management, IT support, administrative services, and non-weapons research at DOE sites often require an L clearance. This is the most common DOE clearance for contractor personnel.
