David Bowering & Greg Knox - “Sulphur Dioxide Pollution: Health Impacts and Mitigation Options”
From CTLT User on February 8th, 2019
Presentation Date: April 5 2018 We will critically review the process leading to Rio Tinto being permitted to significantly increase SO2 emissions from its Kitimat smelter and ask whether the process adequately protects the health of people in the Kitimat/Terrace airshed. We will then review the technical options for reducing sulphur dioxide emissions. Detailed options were researched by Rio Tinto prior to receiving a permit to increase SO2 levels from 27 to 42 tonnes per day. Drawing on Rio Tinto’s own expertise, the literature, and examples of other smelters, the viability of different technologies to reduce pollution will be reviewed, including their effectiveness, environmental impacts, and costs.
