DHS Compliance with the National Environmental Policy Act

The National Environmental Policy Act of 1969 (NEPA) is the federal government's charter for protection of the human environment. Through NEPA, Congress directed federal agencies to integrate environmental considerations into their planning and decision making. The NEPA process provides agency decision makers and the public with an understanding of the potential environmental impacts of proposed actions.

In accordance with NEPA, DHS prepares environmental documentation to identify and assess the potential for environmental impacts associated with proposed DHS activities and projects. NEPA documents include Environmental Assessments (EA), Findings of No Significant Impact (FONSI), Environmental Impact Statements (EIS), and Records of Decision (ROD). As a part of the process, DHS works in a collaborative manner with diverse stakeholders including local and state government, Native American Tribes, Federal land managers, and the interested public to identify, understand, and, to the extent possible, minimize impacts to the environment. DHS invites members of the public to participate in the Department's NEPA process by reviewing documents and findings issued by the Department, and providing comments during the public comment period.

Environmental Impact Statements

  • There are currently no Environmental Impact Statements available for public review and comment.
  • Please check the CBP, FEMA, and USCG environmental websites for additional documents.
