"Mount Polley Mine: ‘Indigenous Law’ Will Now Be Enforced", 23 Feb 2015

...[The] rights of Native communities are often at risk [from extractive industry operations]...Native peoples face [dangers] from overlooked mechanical or structural failures...[involving] waste compounds... That danger was illuminated in brutal clarity last August when a tailings pond in British Columbia, Canada [operated by Imperial Metals] failed, spewing 2.5 billion gallons of waste into nearby waterways...[that] First Nations communities...depend on...for food, water and livelihood... 

Secwepemc [First Nation]...invoked its rights as a sovereign...and evicted Imperial Metals... It also announced that it now had mining policies of its own, and would enforce... ”One thing I want to make perfectly clear is this policy isn’t a wish-list,” said Jacinda Mack...council coordinator for the Secwepemc Nation. “This is Indigenous law.”
