DOE/EIS-0423, DOE/EIS-0423-S1, DOE/EIS-0423-S2: Interim Action Determination (March 17, 2022)

In accordance with the terms of the settlement agreement between DOE and Nevada Gold Mines, LLC, DOE’s Office of Environmental Management (EM) proposes to accept title to the 112 metric tons (MT) of mercury from the NGM facilities and to provide interim management and storage of this elemental mercury in a permitted facility selected by DOE based on responses to the RTP. DOE may award a task order for up to 120 MT to allow margin above the amount of mercury stipulated in the settlement agreement and to provide flexibility without having to re-evaluate minor increases above 112 MT. The analysis in this Interim Action Determination (IAD) evaluates 120 MT of mercury, although only 112 MT is expected.
