Sixteen alternate spent shale disposal sites for Tract C-a prototype oil shale project were identified. One was on-tract; fifteen were off-tract. environmental evaluation was made of these disposal areas to identify sites best suited for this purpose. The DARE model was chosen to be the vehicle for this evaluation. Nine major criteria containing forty-four minor criteria were identified as important to the decision-making process. These were evaluated by a nine-member expert panel using the literature, input from numerous other professionals, and on-site assessments. A detailed description is presented to enable the reader to follow the procedures in step-wise fashion so that he may use the model. Four sites were determined to be environmentally superior: Rinky Dink Gulch, 84 Mesa, Dry Fork and Yellow Creek.
