This information sheet explains the concept of maximum allowable loads and how these have been applied at the Devon and Pakan Long-term River Network monitoring stations. Maximum allowable loads represent the maximum amount of contaminants that a body of water can receive while still meeting water quality objectives.

Description

The methodology of environmental impact analyses incorporates the principle of subjective assessment of the impacts of the separate actions which comprise the project upon various factors of the environment. The significant factors relating to effects on the physical and chemical characteristics of the northern Alberta environment as a result of potential oil sands development in the Athabasca tar sands were documented according to the "Procedure for Evaluating Environmental Impact" - Geological Survey Circular 645. The text of this impact report was based on the sum of magnitude and importance vectors being equal to or greater than 5 for any specific sector of the physical and chemical environment. This report and possible computer data adaptation may provide for additional summation and recommendation of specific actions incurred by oil sands development as these proposals further relate to biological and cultural aspects of the environment.
