The pond located at the Loadout site has become eligible for release. As part of Kerr's regular site maintenance activities, the surface water control structure at the Loadout was inspected. Any concerns noted by the DRMS in their regular site inspection reports were considered. For certification, the pond/embankment was inspected by a registered P.E., Mr. Brian Len of NWCC, Inc. of Steamboat Springs, Colorado during April, 2010.
