This review summarizes the performance of Canadian metal mines with respect to the selected standards prescribed by the Metal Mining Effluent Regulations, which came fully into force on December 6, 2002.
The Regulations require sampling of effluent and the submission of quarterly and annual reports of results within specified time limits. The data used in this review were provided to Environment Canada under section 22 of the Regulations, which requires mines to submit annual reports to Environment Canada. The format for these reports is specified in Schedule 6 of the Regulations. The reports include:
- monthly mean concentrations for metals and total suspended solids;
- monthly pH range; and
- summary results of rainbow trout acute lethality tests and Daphnia magna monitoring tests.
In 2013, 121 mining facilities operating in Canada were subject to the Regulations. No metal mines were subject to the Regulations in Alberta or Prince Edward Island. General information on those facilities subject to the Regulations is provided in Appendix B, and their locations are illustrated on the map in Figure 1.
