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.

NEPA Documents for Public Review and Comment

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.

Environmental Assessments

  • In accordance with the National Environmental Policy Act (NEPA) of 1969 (42 U.S. Code §§ 4321-4347), the Department of Homeland Security Science and Technology Directorate (DHS S&T) plans to conduct a scientific study on aerosol particle behavior in New York City. The study will include the controlled release of safe tracer particles and inert gas at several street-level and transit locations in Manhattan that include Times Square, World Trade Center complex, Union Square, and Grand Central Station. The purpose of this study is to gather data on the behavior of aerosolized particles in a complex urban environment, including concentrations both in air and through deposition on environmental surfaces. This study is part of the Department’s ongoing commitment to public safety against the intentional release of substances that are harmful to human health. Questions or comments on the Environmental Assessment of Proposed Tracer Particle and Gas Releases may be submitted to: urbantest2021@hq.dhs.gov. Comments are due September 17, 2021.
  • In accordance with the National Environmental Policy Act (NEPA) of 1969 (42 U.S. Code §§ 4321-4347), U.S. Immigration and Customs Enforcement (ICE) has prepared a draft El Paso Service Processing Center Draft Environmental Assessment (EA). The project would ensure that adequate facilities and infrastructure resources are available for the efficient and lawful operation of the El Paso SPC. Comments on the draft EA should be submitted by email to ICESustainability@ice.dhs.gov or by mail to: U.S. Immigration and Customs Enforcement Attn: Sustainability Program 500 12th Street SW, STOP 5703 Washington, DC 20536. Comments are due September 1, 2021.
  • Please check the CBP, FEMA, and USCG environmental websites for additional documents.
