"Based on the results of the Environmental Protection Service (EPS) pulpmill effluent toxicity program (1976 to 1979) the percentage of bioassays passing the provincial 90% effluent toxicity standard at the Finlay pulpmill has ranged between 31% to 50% annually. For the Mackenzie pulpmill the percentage passing has ranged from a low of 44% in 1976 to 100% in 1977. The 1978 and 1979 results indicate the Mackenzie pulpmill is not consistently meeting the 100% effluent toxicity standard or the 90% effluent toxicity standard"--Summary and conclusions, page vii.
