Oil Sands Environmental Study Group realized that one of the better ways to create an atmosphere in which the industrial and environmental research worker could engage in constructive dialogue would be the provision of as much technical information as time would permit. We have learned from previous disagreements that the main obstacle to mutual appreciation and understanding resides in an insufficient appreciation of the technical aspects of oil sands resource extraction technology and development on the environmental side, and a lack of comprehension of desirable environmental protection objectives on the industrial side. You may place this seminar in the larger context of our belief that through provision of adequate technical information, industry can assist environmental researchers in the identification of the environmental problems attending oil sands development that require resolution.
