By letter dated July 18, 2014 (ADAMS Accession No. ML14209A660), WCS requested an exemption from NRC regulations to possess SNM in excess of ( printed page 73649) the critical mass limits specified in 10 CFR 150.11 while temporarily storing specific waste at a different location at the WCS facility other than the TSDF. The WCS exemption request referenced the WCS June 20, 2014, letter to the NRC (ADAMS Accession No. ML14171A554) that notified the NRC of actions that WCS had taken in response to the on-going U.S. Department of Energy (DOE) investigation of an unplanned radiation release event at the DOE Waste Isolation Pilot Plant (WIPP) facility ( i.e., the WIPP incident). The specific waste includes some of the transuranic waste that originated at the DOE Los Alamos National Laboratory (LANL), which are destined to be disposed of at the DOE WIPP facility ( i.e., LANL waste). Due to the February 14, 2014, WIPP incident, the DOE suspended operations at the WIPP facility.
