Description

The purpose of the study is to provide the technical background needed to assist Alberta Environment when considering setting air emission standards for new pulp and paper mills. It also provides an assessment of the air emission performance of Alberta’s mills both in terms of existing mills and new world class mills elsewhere.

Description

The objective of this report is to determine whether the ecological effects of treated bleached kraft pulp mill effluent on aquatic invertebrates vary with water temperature. To address this objective, we initially summarized existing studies that evaluated the interactive effects of water temperature on the toxicity of a variety of compounds to aquatic invertebrates. This review indicated that there is a moderately large amount of information indicating that toxic effects of contaminants or other physicochemical stressors can vary with water temperature. These interactive effects between contaminant concentrations and water temperature raise the issue of whether toxic effects of pulp mill effluents that are typically evaluated at 15oC to 20oC, are representative of those at lower temperatures. This is relevant to rivers receiving pulp mill effluent in Alberta, which have lowest dilution capacity in winter, when water temperatures are near 0oC for five months or more. Our review of...

Sediment oxygen demand during the winter in the Athabasca River and the Wapiti-Smoky River system, 1990

Description

Sediment Oxygen Demand (SOD) is an important variable in the oxygen balance of rivers, in particular during the winter under low flow and extensive ice-cover. In 1989, a method to measure SOD... More ≫

Description

Sediment Oxygen Demand (SOD) is an important variable in the oxygen balance of rivers, in particular during the winter under low flow and extensive ice-cover. In 1989, a method to measure SOD in-situ was developed and used to measure winter SOD rates in the Athabasca River. The main objectives of the 1990 study were to determine if SOD rates increased over the winter and to determine the longitudinal trend of SOD in the Athabasca River and the Wapiti-Smoky River system.

The proposed Alberta-Pacific pulp mill : report of the EIA Review Board

Although the proposed mill would be one of the least polluting bleached kraft pulp mills in the world, and even though it would have economic benefits associated with it, the Review Board... More ≫

Description

Although the proposed mill would be one of the least polluting bleached kraft pulp mills in the world, and even though it would have economic benefits associated with it, the Review Board recommends that it not be approved at this time. The major reason for this recommendation is the effluent which would be discharged to the Athabasca River, and in particular, its content of chlorinated organic compounds and the cumulative effects this effluent and that from other mills would have on the Athabasca-Peace River system. The Alberta-Pacific would use technology which would reduce the chlorinated organic compounds to a low concentration. However, the limited available data indicate that there are already measurable amounts of dioxins and furans in fish in the river system near existing mills and extending to more than 1000 km downstream.

Description

Pulp mills discharge significant amounts of wastewater which have the potential to affect water quality in receiving waters. The Alberta-Pacific Environmental Impact Assessment Review Board has been established to examine the potential water quality impacts of pulp mills in the Peace and Athabasca River systems. Alberta Environment has monitored water quality in these rivers for a number of years and has carried out assessments of the impact of existing pulp mill effluents on river water quality and aquatic biota. It is the purpose of this document to outline the monitoring done to date, to summarize the findings of these assessments regarding pulp mill effects, and to indicate the direction of future river monitoring and assessments.
