This report is one of a series that addresses potential human health, environmental and socio-economic impacts of Suncor Inc., Oil Sands Groups Steepbank Mine project and reclamation of Suncor's existing leases. Specifically this report addresses potential impacts on people arising from construction, operation, and extraction or upgrading and reclamation activities related to the Steepbank Mine and reclamation of Suncor exists mine. This impact assessment is based on testing specific hypotheses of potential impacts of the project on people's health and safety. In particular, three groups of people were considered. One group consists of workers on the site that might be exposed to chemicals, noise and other physical site hazards such as heavy equipment. A second group included people who live; work or engage in recreational activities recreate near Suncor's operations and who may be affected by air and water emissions that are not contained on-site. A third group includes those people who might use the existing mined-out areas following closure and reclamation. The interrelationship of the impact hypotheses investigated in the human health study is presented in Table A-1.The remainder of this report outlines the impact assessment framework, describes the existing environmental characteristics that are pertinent to the to the impact assessment, presents the results of the impact analysis and discusses proposed activities to monitor and test specific impact predictions.
