British Columbia Mine Reclamation Symposium

Reclamation of Inco’s Canadian operations : research and practices Lanteigne, Lisa


While Inco has been reclaiming mining impacted land for many decades, an in-depth planning process for the closure of its operating sites, along with a commitment to rehabilitate its inactive sites, began in the 1990's. Changes to the Mining Act in 1991 required mining companies to submit detailed closure plans for all active properties, and as such Inco submitted 15 plans between 1994 and 1998. Further changes to this legislation in 2000 led to the resubmission of all of these plans as certified documents in 2001. This paper will review Inco's process for developing closure plans for the Ontario Division, including descriptions of the technical studies completed in support of the plans, and the rationale for the selection of closure concepts. The paper will also outline some of the research initiatives that Inco has undertaken over the years to assist in developing cost-effective and environmentally responsible closure techniques. Examples of closure plan implementation at a variety of sites will be provided.
