This environmental impact statement examines the environmental and socioeconomic impacts that would result from that proposed action. The purpose of this document is to assist the Secretary of Interior in making a decision on whether or not to hold a lease sale in March 1983, and if one is held, which tracts to offer. It supplements the 1973 Prototype Environmental Impact Statement, updating environmental data which has become available since that time, and analyzing the impacts of leasing an additional tract that was not included in that document.
