Amended Record of Decision: Idaho High-Level Waste and Facilities Disposition Final Environmental Impact Statement

Riepilogo

The U.S. Department of Energy (DOE) is amending its Record of Decision (ROD) published December 19, 2005 (70 Federal Register [FR] 75165), pursuant to the Idaho High-Level Waste and Facilities Disposition Final Environmental Impact Statement (Final EIS) (DOE/EIS- 0287, September 2002). The Final EIS analyzed two sets of alternatives for accomplishing DOE's proposed actions regarding the Idaho Nuclear Technology and Engineering Center (INTEC): (1) Waste processing alternatives and (2) facility disposition alternatives. As described in this Amended ROD, DOE has decided to conduct performance-based closure of the INTEC Tank Farm Facility (TFF). This decision to conduct performance-based closure of the TFF does not affect decisions made in the initial ROD concerning: performance-based closure of other existing facilities directly related to the HLW Program; planned clean closure of newly constructed waste processing facilities needed to implement the initial ROD; steam reforming treatment of sodium-bearing waste (SBW) to allow disposal at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico (DOE's preferred disposal path) or at a geologic repository for spent nuclear fuel (
