It’s taken more than two decades to even come up with a proposed remediation plan, and that plan is still being screened by Yukon’s environmental assessment board. In the meantime, until the plan is approved, the mine site is in care and maintenance mode.
The remediation is expected to take about 15 years, followed by 20 to 25 years of testing and monitoring. Some areas of the mine site will “always remain under active management and monitoring,” the federal government says.
Earlier this year, U.S.-based Parsons Corporation was awarded a contract to implement the remediation plan and provide ongoing care and maintenance at the site. A news release from the company boasts that the contract “could span over 20 years and exceed $2 billion.”
