Reclamation

What is reclamation?

Reclamation, in the context of oil sands mining, is the term used to describe the three phases of reclamation of boreal forest ecosystems following mining operations.

The first phase is the placement of the subsoil on the various mine substrates that have been contoured to the desired landscape design (if applicable). The depth of replaced subsoil depends on the quality of the underlying substrate (overburden, tailings).

The second phase is the placement of the coversoil to various depths according to the applicable reclamation prescriptions. Mixes of mineral soil and peat can be used to provide a suitable growing medium, as can salvaged upland surface soil.

The third phase is the revegetation and/or reforestation phase, which is undertaken shortly after the second phase.

The operator monitors lands that have completed all three phases of reclamation. The operator can apply for a reclamation certificate when they are satisfied that the reclaimed land will meet the specific reclamation certification criteria for that landform.

Reclamation also includes lands that are considered temporary reclamation, where further disturbance or reclamation will occur. These areas usually form a very small proportion of the total mine reclamation area.
