The discussion of Federal environmental statutes is intended to guide planners of Federal agencies and other interested individuals through some of the land use aspects of these laws, point out the planning constraints they impose, and draw attention to ongoing Federal, state, and local planning activities that may affect the programs of other Federal agencies. Because of the breadth of the materials covered and the rapid pace of events in this field, the package has been designed to provide a brief introduction to certain planning and land use aspects of several complex pieces of environmental legislation together with sources of current, detailed information that will be useful in carrying out the programs of various agencies in harmony with EPA's legal mandates.
