EIS-0350: Draft Environmental Impact Statement

Chemistry and Metallurgy Research Building Replacement Project at Los Alamos National Laboratory, Los Alamos, New Mexico

NNSA, an agency within DOE, proposes to replace the Chemistry and Metallurgy Research (CMR) Building at Los Alamos National Laboratory (LANL). The CMRR EIS will examine the potential environmental impacts associated with the proposed action of consolidating and relocating the mission-critical CMR capabilities from a degraded building to a new modern building(s).The CMRR EIS evaluates the potential direct, indirect, and cumulative environmental impacts associated with the proposed action. The Proposed Action is to replace the CMR Building. The Preferred Alternative is to construct a new CMRR Facility at Technical Area (TA) 55, consisting of two or three buildings. One of the new buildings would provide space for administrative offices and support functions. The other building(s) would provide secure laboratory spaces for research and analytical support activities. The buildings would be expected to operate for a minimum of 50 years. Tunnels may be constructed to connect the buildings. Alternative 2 would be to construct the new CMRR Facility within an undeveloped “greenfield” area near TA-55 at TA-6. Alternatives 3 and 4 would be to continue using the existing CMR Building for administrative offices and support functions with the implementation of minimal necessary structural and system upgrades and repairs, together with the construction of new nuclear laboratory building(s) at either TA-55 or TA-6. The EIS also presents an analysis of impacts associated with the dispositioning of all or portions of the existing CMR Building.
