Nutrien is a Canadian fertilizer company that has six potash mines in Saskatchewan, Canada. It is the largest producer of potash and the third largest producer of nitrogen fertilizer in the world. The company has been proactive in maintaining the integrity of its tailings facilities through ongoing assessment, design, operation, inspection and monitoring.
Nutrien recently commissioned a system inventory and semiquantitative risk analysis (SQRA) of all its dikes to further environmental stewardship at its potash facilities. The inventory assessed nearly 100 dikes. Each dike was rated according to a probability and consequence factor and assigned a risk score.
