National Environmental Policy Act of 1970:
P.L. 91-190 (January 1, 1970) made a declaration of national environmental policy and established a continuing responsibility of the federal government to reach a number of substantive goals that embody nationwide improvements in environmental quality. Federal policies, regulations, and laws must be administered in accordance with NEPA. To insure this is accomplished, all federal agencies must consider the environmental consequences of their actions through the preparation of environmental impact statements (EIS). Also, the law creates the Council on Environmental Quality in the Executive Office of the President.
