Final Supplemental Environmental Impact Statement for CMRR

Chemistry and Metallurgy Research Replacement – Nuclear Facility (CMRR-NF) SEIS

The Department of Energy, National Nuclear Security Administration’s (NNSA’s) Chemistry and Metallurgy Research Building Replacement (CMRR) Project entails the proposed replacement of the existing Chemistry and Metallurgy Research (CMR) Building at the Los Alamos National Laboratory (LANL) with two new buildings, and relocating certain CMR capabilities from the aging building to the new facility. The nuclear facility portion of the CMRR Project would provide the analytical chemistry and materials characterization capabilities required to support a broad range of NNSA mission activities at LANL.

NNSA has completed the Final Supplemental Environmental Impact Statement for the Nuclear Facility Portion of the Chemistry and Metallurgy Research Building Replacement Project at Los Alamos National Laboratory, Los Alamos, New Mexico (CMRR-NF SEIS), DOE/EIS-0350-S1. NNSA prepared this document in accordance with the National Environmental Policy Act (NEPA) and its implementing regulations. It supplements the CMRR EIS (DOE/EIS-0350) completed in 2003 (which was followed by a Record of Decision (ROD) issued in 2004). This supplement was prepared to address new geologic information regarding seismic conditions at the site and examines the potential environmental impacts associated with NNSA’s proposed action to complete the CMRR Project at LANL.

A 60-day public comment period followed issuance of the Draft CMRR-NF SEIS.  NNSA held public hearings on the Draft CMRR-NF SEIS in Albuquerque, Los Alamos, Espanola, and Santa Fe, New Mexico, from May 23 through May 26, 2011. The Final CMRR-NF SEIS contains revisions and new information based in part on comments received on the Draft CMRR-NF SEIS.  Vertical change bars in the margins of the Final CMRR-NF SEIS indicate the locations of revisions and new information.  Volume 2 of the Final CMRR-NF SEIS contains the comments received on the Draft CMRR-NF SEIS and NNSA’s responses to the comments.

NNSA will use the analysis presented in this Final CMRR-NF SEIS, as well as other information, in preparing its future Record(s) of Decision (RODs) regarding CMRR-NF. NNSA will issue a ROD no sooner than 30 days after the U.S. Environmental Protection Agency publishes a Notice of Availability of the Final CMRR-NF SEIS in the Federal Register.
