Facilities for controlling pollution, managing wastes and maintaining air quality are constantly improved by the company's potash operations. Environmental audits are regularly conducted to ensure compliance with regulations and corporate environmental policy.

Construction of an impervious cutoff wall to prevent sub-surface seepage from Rocanville's tailings management area was completed in 1998. This wall is one of the longest and deepest in Canada. It incorporates design features developed through research sponsored by the Saskatchewan potash industry.

PotashCorp participates in the environmental research program on improved management of potash tailings and decommissioning of plants that is jointly supported by members of the Saskatchewan Potash Producers Association. PotashCorp is also conducting in-house research aimed at developing technology that will extend the life of tailings management areas.

A decommissioning and reclamation plan for each of the PotashCorp Saskatchewan potash mines has been submitted to Saskatchewan Environment. The regulatory agency approved the technical aspects of these plans but discussions on the schedule for their implementation continue. Discussions are also continuing on the form of the financial assurance which is to be arranged within one year after approval of the plans.

PotashCorp has an active recycling program. Contracts are in place with licensed recycling companies to remove all waste oils, solvents and batteries. Waste paper is given to a local charity and scrap metals are sold or given to local salvagers. The company purchases recycled oil for use as a dedusting agent on potash.
