The National Environmental Policy Act requires federal agencies to take into account the environmental impacts of federal decisions which could significantly affect the environment. In implementing NEPA, federal agencies have to assess the environmental impacts of decisions and inform the public of any impacts. The public has the right to comment on any proposed EIS before action is taken.
