Description This study basis consists of the assumptions for conducting the Columbia River Vessel Traffic Risk Assessment.

The intent of this document is to clarify and confirm the assumptions made by DNV GL related to how the aspects of the marine transit route, including the marine traffic itself, have been collected, interpreted, and applied in the DNV GL marine traffic risk analysis.

These assumptions form the basis for the oil spill risk assessment. If any of these assumptions are altered, the results presented for the study are no longer valid. Consequently, alteration of any of these assumptions may generate a need for an update of the analysis.
