CMRR Draft Supplemental EIS available online

-A A +A

The National Nuclear Security Administration (NNSA) has announced that the Draft Supplemental Environmental Impact Statement for the Nuclear Facility portion of the Chemistry and Metallurgy Research Replacement (CMRR) Project at Los Alamos National Laboratory is now available online.
The CMRR would replace the 60-year-old Chemistry and Metallurgy Research Building used for analytical chemistry and materials characterization critical to NNSA national security missions that require nuclear materials handling, processing and fabrication including stockpile management, nonproliferation and counterterrorism.
The CMRR Project was the subject of a 2003 Final Environmental Impact Statement. The Record of Decision to construct a two-building replacement facility came in 2004. 

The Draft SEIS analyzes three alternatives:
1.      No Action Alternative: Construct and operate a new CMRR-NF at Technical Area 55, adjacent to RLUOB, as analyzed in the 2003 CMRR EIS and selected in the associated 2004 Record of Decision.

2.      Modified CMRR-NF Alternative: Construct and operate a new CMRR-NF at TA-55, adjacent to RLUOB, with certain design and construction modifications and additional support activities. The design modifications address seismic safety, infrastructure enhancements, nuclear safety-basis requirements, and sustainable design principles. This alternative, which is NNSA’s preferred alternative, has two construction options, a Deep Excavation Option and a Shallow Excavation Option. No preferred construction option has been identified.

3.      Continued Use of CMR Building Alternative: NNSA would not construct a replacement facility to house the capabilities planned for the CMRR-NF, but instead would continue to perform operations in the CMR Building at Technical Area 3, with normal maintenance and component replacements at the level needed to sustain programmatic operations for as long as feasible.

Distribution of the Draft CMRR-NF Supplemental EIS is under way.  Copies of the document have been mailed to those who have requested to receive a copy. The document is available on the internet at http://nnsa.energy.gov/nepa/cmrrseis.  The EPA’s Notice of Availability is expected to be posted in the Federal Register on April 29, 2011, which will mark the beginning of the 45-day public comment period.
Public hearings are scheduled as follows:
May 24 in Los Alamos at the Holiday Inn Express, 60 Entrada Dr., from 5 to 9 pm
May 25 in Española at the Santa Claran Hotel, 464 N. Riverside Dr., from 5 to 9 pm
May 26 in Santa Fe at Santa Fe Community College, 6401 S. Richards Ave., from 5 to 9 pm
