# SUPPLEMENTARY INFORMATION:

The Council on Environmental Quality's implementing regulations for the National Environmental Policy Act (NEPA) (40 CFR 1502.9[c] [1] and [2]) and DOE's NEPA implementing regulations (10 CFR 1021.314) require the preparation of a supplement to an environmental impact statement (EIS) when there are substantial changes to a proposal or when there are significant new circumstances or information relevant to environmental concerns. DOE may also prepare a supplemental EIS at any time to further the purposes of NEPA. Pursuant to these provisions, the NNSA intends to prepare a supplemental environmental impact statement (SEIS) to assess the potential environmental impacts of the construction and operation of the nuclear facility portion of the Chemistry and Metallurgy Research Building Replacement Project (CMRR-NF) at Los Alamos National Laboratory (LANL), Los Alamos, New Mexico.

                    On October 1, 2010, NNSA published a notice of intent to prepare the                     *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*                     (DOE/EIS-0350-S1). That notice stated that the scoping period would continue until November 1, 2010. In response to public requests, NNSA has extended the public scoping period through November 16, 2010. NNSA will consider comments received after this date to the extent practicable as it prepares the Draft CMRR-NF SEIS.                

Issued in Washington, DC, on November 1, 2010.

Administrator, National Nuclear Security Administration.
