Two years after the Mount Polley disaster, the BC government has announced new changes to the mining code.
It now includes design standards specific to B.C.
In the summer of 2014, the tailings pond at the Mount Polley mine burst, spilling sent 24 million cubic metres of wasterwater into local rivers and lakes, forcing residents in and around the small community of Likely to find other sources of water.
An independent panel found the dam failed because the strength and location of a layer of clay underneath the dam was not taken into account.

The new standards will include rules for the steepness of downstream slopes, the minimum static factor of safety, and new seismic and flood design rules.
They also require plans for tailing pond water and management, and require mines to establish Independent Tailings Review Boards.
Mines Minister Bill Bennett says the changes will ensure that type of disaster can never happen again in BC.
With the changes, the province says it has now implemented 20 of the 26 recommendations from the independent expert panel and the chief inspector of mines’ reports.
It says 17 recommendations made by the Office of the Auditor General have also been accepted, and will be addressed by the end of next year.
