A number of industrial facilities have been proposed for the north coast of British Columbia, and government regulators needed to understand how many facilities, and under what levels of emission control, could be added to the area without causing unacceptable impacts to human health and the environment.

ESSA led a collaborative team of experts to assess the potential combined effects of nitrogen dioxide and sulphur dioxide emissions under scenarios comprising different combinations of existing and proposed emission sources (aluminum smelter, oil refinery, liquid natural gas terminals, gas turbine powered electrical generation facilities, and related marine transportation) and emissions treatment. The objective was to provide information to help decision-makers compare the absolute, and relative, risks under different scenarios.
