Amendment No. 6 to the NAC-MPC System CoC will include the following changes to the configuration of the NAC-MPC storage system as noted in Appendix B of the Technical Specifications (TS): Incorporation of a single closure lid with a welded closure ring for redundant closure into the Transportable Storage Canister (TSC) design; modification of the TSC and basket design to accommodate up to 68 La Crosse Boiling Water Reactor (LACBWR) spent fuel assemblies (36 undamaged Exxon fuel assemblies and up to 32 damaged fuel cans (in a preferential loading pattern)) that may contain undamaged Exxon fuel assemblies and damaged Exxon and Allis Chalmers fuel assemblies and/or fuel debris; the addition of zirconium alloy shroud compaction debris to be stored with undamaged and damaged fuel assemblies; minor design modifications to the Vertical Concrete Cask (VCC) incorporating design features from the MAGNASTOR system for improved operability of the system while adhering to as low as is reasonably achievable (ALARA) principles; an increase in the concrete pad compression strength from 4,000 psi to 6,000 psi; added justification for the 6-ft soil depth as being conservative; and other changes to incorporate minor editorial corrections in CoC No. 1025 and Appendices A and B of the TS. Also, the Definitions in TS 1.1 will be revised to include modifications and newly defined terms; the Limiting Conditions for Operation and associated Surveillance Requirements in TS 3.1 and 3.2 will be revised; and editorial changes will be made to TS 5.2 and 5.4.

Notice is hereby given that the U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment the Draft Environmental Impact Statement (EIS) for the proposed AREVA Enrichment Services LLC (AES) Eagle Rock Enrichment Facility (EREF). On December 30, 2008, AES submitted a license application to the NRC that proposes the construction, operation, and decommissioning of a gas centrifuge-based uranium enrichment facility on a presently undeveloped site near Idaho Falls in Bonneville County, Idaho (the ``proposed action''). The license application included an Environmental Report (ER) regarding the proposed action.
