Diavik 'misunderstood' requirement to report February groundwater spill: N.W.T. inspectors

Diavik 'misunderstood' requirement to report February groundwater spill: N.W.T. inspectors

An N.W.T. diamond mine "misunderstood" its reporting requirements earlier this year when it failed to flag a massive groundwater spill, according to the territorial government.  A broken pipeline leaked 450,000 cubic metres of groundwater — enough to fill 180 Olympic-sized swimming pools — and was first spotted at the Diavik mine on Feb. 7, the N.W.T.'s lands department (now the Department of Environment and Climate Change) said in March.

The Diavik Diamond Mine in the Northwest Territories says 450 million litres of wastewater spilled due to a broken pipeline. The spill took place on Feb. 7 but wasn't reported to the Northwest Territories government until late last week. The territorial government says pipeline operators did not initially believe it needed to be reported as the wastewater leaked into a containment pond that was its final destination.

Environment and Climate Change Canada, heralding Monday’s sentence, said the money will be placed in a fund that supports “projects that benefit the natural environment.” De Beers was charged under the Canadian Environmental Protection Act, a prosecution considered significant as one of the first since the act’s regulations were amended in 2020.

De Beers pleads guilty to failing to report mercury monitoring results at Victor mine

De Beers pleads guilty to failing to report mercury monitoring results at Victor mine

In a resolution to a years-long dispute, De Beers Canada has plead guilty to one count of failing to report annual mercury monitoring results for the G2 station at Victor mine in 2014 as required under the mine’s Certificate of Approval. De Beers was not charged with failing to take samples, monitoring or for polluting the environment. The open-pit diamond mine operated by De Beers Canada Inc. is located upstream from the Attawapiskat First Nation. Beginning in 2008, the project pumped water from the open pit into the Granny Creek water system which flows into the Attawapiskat River, triggering a rise in the mercury level in the water and the fish populations.
