CASSIAR OBJECTIVE "We are now convinced that we can effectively achieve 2 fibres/cc on a time weighted average using the best technology economically available." This statement of our objective by Peter Steen, President of Cassiar Asbestos Corporation Limited, will require effort on everyone's part to 2 ° achieve. In order to know what changes, costs, etc. will be required an accurate assessment of the work place must be available. If an assessment was inac— curately high or low, our environmental costs would soar.
