0358 1.5 1.2 Scope of Issues to be Addressed A supplemental EIS differs somewhat from a formal EIS in that itis designed to provide specific information on selected elements of a project that were not presented in the original EIS. This draft EA will address . alternative procedures for water sales from Ruedi Reservoir, sales which were not discussed in 1975 and will serve as a basis for the supplemental EIS. The scope of the draft EA has been determined from several processes, the most important of which were communications between the Bureau and prospective customers for Ruedi water and public seaping sessions. The communications and the scoping sessions have raised questions and identified issues that need to be addressed before the Bureau can define the procedures for future water sales.
