Companies must post a deposit, but it may fall short of the actual cost of reclamation
As Alberta moves away from coal-fired electricity, the provincial government is trying to ensure it will not be on the hook to clean up old coal mines once they stop operating. The Alberta Energy Regulator is planning to audit nine coal mines beginning by mid-September to ensure that each operator has the security on hand to reclaim the property.
The AER said it is looking for a contractor to “validate that the approval holder’s … security deposit is sufficient for the liability cost of suspension, decommissioning, remediation, monitoring and surface reclamation,” according to a request for proposal posted this month.
In its climate change plan released last November, the provincial government said it will no longer be dependent on coal-fired power by 2030. That means several plants will be shut down many years before their operators had planned.
