Public Scoping Meetings For the LANL SWEIS

PUBLIC SCOPING MEETINGS for SITE-WIDE ENVIRONMENTAL IMPACT STATEMENT FOR LOS ALAMOS NATIONAL LABORATORY IN NEW MEXICO

As NNSA announced in the Federal Register (FR) on Aug. 19, 2022, NNSA is holding a 45-day public scoping comment period on the Site-Wide Environmental Impact Statement (SWEIS) for Continued Operations at the Los Alamos National Laboratory (LANL) in New Mexico (DOE/EIS-0552) from Aug. 19 through Oct. 3, 2022 (87 FR 51083). During the comment period, NNSA is holding two online public scoping meetings to invite public participation in the process and to encourage public input on the scope and alternatives that should be considered in the LANL SWEIS. The LANL SWEIS will analyze the potential environmental impacts of the reasonable alternatives for continuing LANL operations for approximately the next 15 years. In light of current public health concerns, NNSA will be hosting two internet-based (with telephone access), virtual scoping meetings in place of in-person meetings. The meetings will occur on the following dates:

Notice of Intent to prepare a Site-Wide Environmental Impact Statement for the Los Alamos National Laboratory

NNSA published a Notice of Intent (NOI) in the Federal Register on Aug. 19, 2022, to announce its intent to prepare a Site-Wide Environmental Impact Statement (SWEIS) for the Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico, (LANL SWEIS). The LANL SWEIS will be prepared by NNSA’s Los Alamos Field Office (LAFO) to meet the requirements of the National Environmental Policy Act (NEPA). The LANL SWEIS will analyze the potential environmental impacts of the Proposed Action, other reasonable alternatives that may be identified, and the No Action Alternative for continuing operations of LANL for approximately the next 15 years.

NNSA invites Federal and state agencies, state and local governments, Native American tribes, industry, other organizations, and members of the public to submit comments to assist in identifying environmental issues and determining the appropriate scope of the LANL SWEIS from Aug. 19 through Oct. 3, 2022.

Written comments on the scope of the SWEIS or requests for information related to the LANL SWEIS should be sent by Oct. 3 to:

LANL SWEIS Comments
3747 W. Jemez Road
Los Alamos, New Mexico 87544

Or email to: LANLSWEIS@nnsa.doe.gov

For receiving oral comments, NNSA will host two virtual public scoping meetings. The decision to hold only virtual meetings is based on the continuing high level of community spread of COVID-19 in the areas where in-person meetings would be held, as measured and reported by the U.S. Centers for Disease Control and Prevention. Meeting details will be provided in a future notice posted on this page. NNSA will hold the scoping meetings no earlier than 15 days from the posting of the notice. Details of the public meetings will also be announced in local media outlets.

Before including your address, phone number, email address, or other personally identifiable information in your comment, please be advised that your entire comment—including your personally identifiable information—might be made publicly available. If you wish for NNSA to withhold your name and/or other personally identifiable information, please state this prominently at the beginning of your comment. You may submit comments anonymously.

NEPA Terminology

  • Environmental Assessment (EA) - A concise public document that a Federal agency prepares under NEPA to provide sufficient evidence and analysis to determine whether a proposed agency action would require preparation of an environmental impact statement or a finding of no significant impact.
  • Environmental Impact Statements (EIS) - The detailed written statement that is required by section 102(2)(C) of NEPA for a proposed major Federal action significantly affecting the quality of the human environment.
  • Finding of No Significant Impact (FONSI) - A public document issued by a Federal agency briefly presenting the reasons why an action for which the agency has prepared an environmental assessment will not have a significant effect on the human environment and, therefore, will not require preparation of an environmental impact statement.
  • A Floodplain and Wetland Assessment is an evaluation that DOE prepares under DOE Floodplain and Wetland Environmental Review Requirements (10 CFR Part 1022) consisting of a description of a proposed action, a discussion of its potential effects on the floodplain or wetland, and consideration of alternatives. A Floodplain Statement of Findings is a brief document issued pursuant to 10 CFR 1022.14 that describes the results of the floodplain assessment.
  • A Mitigation Action Plan is a document DOE prepares in accordance with DOE NEPA regulations (10 CFR 1021.331) that describes the plan for implementing commitments made in a DOE environmental impact statement and its associated record of decision, or, when appropriate, an EA or FONSI, to mitigate adverse environmental impacts associated with an action.
  • Notice of Availability (NOA) is a formal notice, published in the Federal Register, that announces the issuance and public availability of a draft or final EIS. The Environmental Protection Agency NOA is the official public notification of an EIS; a DOE NOA is an optional notice used to provide information to the public.
  • Notice of Intent (NOI) is a formal announcement of intent to prepare an EIS as defined in Council on Environmental Quality (CEQ) NEPA regulations (40 CFR 1508.22). DOE publishes NOIs in the Federal Register in accordance with DOE NEPA regulations (10 CFR 1021.311). On rare occasions we may produce and issue an Advance NOI which means a formal public notice of DOE's intent to prepare an EIS, which is published in advance of an NOI in order to facilitate public involvement in the NEPA process.
  • Programmatic NEPA document means a broad-scope EIS (PEIS) or EA that identifies and assesses the environmental impacts of a DOE program; it may also refer to an associated NEPA document, such as an NOI, ROD, or FONSI.
  • A Record of Decision (ROD) is a concise public document that records a Federal agency's decision(s) concerning a proposed action for which the agency has prepared an environmental impact statement (See CEQ and DOE NEPA regulations at 40 CFR 1505.2 and 10 CFR 1021.315, respectively).
  • Scoping means the process described at 40 CFR 1501.7; “public scoping process” refers to that portion of the scoping process where the public is invited to participate, as described at 40 CFR 1501.7 (a)(1) and (b)(4).
  • Site-wide NEPA document means a broad-scope EIS (SWEIS) or EA that is programmatic in nature and identifies and assesses the individual and cumulative impacts of ongoing and reasonably foreseeable future actions at a DOE site; Site-wide may also refer to an associated NEPA document, such as an NOI, ROD, or FONSI.
  • Supplement Analysis (SA) means a DOE document used to determine whether a supplemental EIS should be prepared pursuant to 40 CFR 1502.9(c), or to support a decision to prepare a new EIS.
  • Supplemental EIS (SEIS) means an EIS prepared to supplement a prior EIS as provided at 40 CFR 1502.9(c).
