EA-1793: Final Environmental Assessment

Replacement Capability for Disposal of Remote-Handled Low-Level Radioactive Waste Generated at the Department of Energy’s Idaho Site

The U.S. Department of Energy (DOE) proposes to provide replacement capability for disposal of remote-handled low-level radioactive waste (LLW) generated at the Idaho National Laboratory (INL) site beginning in October 2017. Historically, INL has disposed of this LLW onsite at a disposal area located within INL’s Radioactive Waste Management Complex (RWMC). Disposal activities ceased at a portion of this onsite LLW disposal facility in 2008. The entire LLW disposal facility will undergo closure as part of ongoing Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) cleanup of INL and will not be available after 2017. The proposed project to establish replacement capability is not a DOE Environmental Management Idaho Cleanup Project activity.

DOE has prepared this environmental assessment to evaluate potential environmental impacts related to replacement capability options for the disposal of remote-handled LLW generated on the INL site. DOE will continue to dispose of contact–handled LLW (waste having lower levels of radiation) off-site at acceptable disposal facilities.
