On May 20, 2026, AWA submitted a Statement of Concern (SOC) to the Alberta Energy Regulator (AER) on the Applications (#: 1961168, 020-00155804) by CST Canada Coal Ltd. to construct the No. 12 South A Underground Mine at the Grande Cache Coal Mine.
In a previous review of CST’s recent and available air, water, soil, and wildlife monitoring reports by a toxicological expert, it was apparent that current management practices are not performing as expected and require updating to reduce the impacts of CST’s existing operations on the environment.
AWA believes that CST’s monitoring and mitigation efforts are insufficient to protect the landscape, watershed, and atmosphere, and requested that any consideration of the project be denied until these issues are resolved.
