Proposed Approval of the Central Characterization Project's Remote-Handled Transuranic Waste Characterization Program at Sandia National Laboratory

Riepilogo

The Environmental Protection Agency (EPA or we) is announcing the availability of, and soliciting public comments for 45 days on, the proposed approval of the radioactive, remote-handled (RH), transuranic (TRU) waste characterization program implemented by the Central Characterization Project (CCP) at Sandia National Laboratory (SNL) in Albuquerque, New Mexico. This waste is intended for disposal at the Waste Isolation Pilot Plant (WIPP) in New Mexico. In accordance with the WIPP Compliance Criteria, EPA evaluated the characterization of RH TRU debris waste from SNL-CCP during an inspection conducted in three steps: Observation of the Visual Examination (VE) and sampling process at SNL on March 8, 2011; dose-to- curie (DTC) measurements on May 10, 2011 at SNL; and, the formal baseline inspection on June 7-8, 2011 in Golden, Colorado. Using the systems and processes developed as part of the U.S. Department of Energy's (DOE's) Carlsbad Field Office (CBFO) program, EPA verified whether DOE could adequately characterize RH TRU waste consistent with the Compliance Criteria. The results of EPA's evaluation of SNL-CCP's RH program and its proposed approval are described in the Agency's in
