AER gives Suncor a second chance
The Alberta Energy Regulator (AER) has agreed to reconsider Suncor's tailings management plan for its Millennium Mine. The provincial regulator rejected the company's plans to water-cap its fine fluid tailings (FFT) last March, calling the proposal "unproven technology."
Suncor says it was not able to provide more specific details prior to obtaining patent protection for the technology. However, the company will provide the AER with more data on the process.
If left untreated, FFT can take decades (or even centuries) to settle and dewater, preventing the timely reclamation of tailings storage ponds. FFT capture plans must be approved by the AER under the province's Tailings Management Directive 085.
