Corps of Engineers, and Bonneville Power Administration wish to thank those who reviewed the Columbia River System Operation Review (SOR) Draft EIS and appendicesfor theircomments. Yourcomments have provided valuablepublic,agency,andtribal input to the SOR NEPA process. Throughout the SOR. we have made a continuing effort 10 keep the public informed and involved. Fourteen public seeping meetings were held in 1990. A series of public roundtables was conductedinNovember 1991 to providean update on thestatus ofSOR studies. The leadagencies went back to most of the 14 communities in 1992 with 10 initial system operating strategies' developed from the screening process. From those meetings and oilierconsultations.seven 50S alternatives (with options) were developed and subjected to full-scale analysis. The analysis results were presented in the Draft EIS released in July 1994. The lead agencies also developed alternatives forthe other proposed SOR actions. including a Columbia River RegionalForum for assisting in the determination of future SOSs. Pacific Nonhwest Coordination Agreement alternatives for power coordination. and Canadian Entitlement Allocation Agreements alternatives. A series of nine public meetingswas held inSeptember and October 1994to present the Draft EISand appendices andsolicit public inputon the SOR. The lead agencies-received 282 formal written comments. Yourcomments have been used to revise and shape the alternatives presented in the Final EIS. Regular newsletters on the progress of the SOR have been issued. -
