Proposed Coal Mining Effluent Regulations: overview ...

2021-6-17  Effluent from coal mines in Canada can be a source of pollution that harms aquatic life and specifically fish and fish habitat. The evidence of environmental effects is clear and Canada is moving to address the issue. Environment and Climate Change Canada (ECCC) is developing Coal Mining Effluent Regulations under the Fisheries Act. These Regulations will reduce the risks to fish and fish habitat by limiting levels of harmful substances in coal mining effluent.
