Congress enacted the National Environmental Policy Act (NEPA) in 1969 and President Nixon signed it into law on January 1, 1970. Congress enacted NEPA to establish a national policy for the environment, provide for the establishment of the Council on Environmental Quality (CEQ), and for other purposes.
