U16a is not listed in the Federal Facility Agreement and Consent Order. The closure of U16a was sponsored by the Defense Threat Reduction Agency (DTRA) and performed with the cooperation of the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office and the Nevada Division of Environmental Protection.

Closure activities included: ¡ Removing and disposing of a shack and its contents ¡ Disposing of debris from within the shack and in the vicinity of the tunnel entrance ¡ Verifying that the tunnel is empty ¡ Welding screened covers over tunnel vent holes to limit access and allow ventilation ¡ Constructing a full-tunnel cross-section fibercrete bulkhead to prevent access to the tunnel Field activities were conducted from July to August 2008.
