environmental impact statement
A written report containing an analysis of the ecology and general environment of an area, together with projections regarding how that will change during construction of the project and after completion and public usage.These statements were originally required by the National Environmental Policy Act of 1969, but only for federal projects. Today, most state and local governments require these statements for all large projects and selected smaller ones.The vast collection of federal environmental impact statements, for projects ranging from Alaska to Antarctica, may be accessed online at the Web site for the Transportation Library of Northwestern University,nucat.library.northwestern.edu.
