GNWT mulling shutdown of Diavik watchdog before closure ends – Cabin Radio

The owner of Diavik wants the NWT government to shut down an environmental oversight board before the mine closes. The board says it should remain in place until reclamation of the site is complete.
The Environmental Monitoring Advisory Board, or Emab, is the independent watchdog for Diavik. It was established as a requirement under the environmental agreement for the diamond mine, which is owned by Rio Tinto, and is made up of representatives from the parties to that agreement.
Matthew Breen, chief operating officer for Diavik, wrote to NWT environment minister Jay Macdonald in January asking him to wind down and conclude Emab as the mine begins its closure phase.
