Fatal Brazilian mine waste disaster shows modern mining is increasingly dangerous

Washington, D.C. -- A mine waste dam at the Germano open-pit iron ore mine in Brazil’s state of Minas Gerais breached yesterday, flooding the downstream area with mining waste and causing fatalities. The Germano facility is co-owned by two of the world’s largest mining companies, Brazilian Vale SA and Anglo-Australian BHP Billiton.

A recent report, The Risk, Public Liability & Economics of Tailings Storage Facility Failure, demonstrates that catastrophic mine waste failures are increasing in frequency and severity because of -- not in spite of -- modern mining techniques, and will continue to do so until regulators and mining companies take active steps to prevent them.

“Our research shows that more mining waste disasters like Brazil’s Germano spill are inevitable,” said David Chambers, report co-author and director of the Center of Science in Public Participation. He continued, “If mining practices continue as usual, we are going to see more severe spills, more frequently. These spills each will cost the public hundreds of millions to billions of dollars to clean up - if cleanup is possible at all. And sometimes, like the Germano spill, they will cost people's lives.”

Chambers’ report, co-authored with Lindsay Newland Bowker, was researched in response to the 2014 Mount Polley mine waste disaster in British Columbia, another waste impoundment failure which released roughly 24.4 million cubic meters of mine tailings waste into the Fraser River watershed. An expert panel commissioned by the BC provincial government recommended the global mining industry make significant changes to how it handles mining waste. To date those recommendations have been largely ignored.

“The Mount Polley disaster should have been a wake-up call to the mining industry,” said Earthworks’ mining director Payal Sampat. She continued, “But mining companies and government regulators failed to act - and tragically, now mining spills are killing people as well as wildlife. We cannot afford to wait for the next mining disaster before we protect communities and the environment from risky mining practices.”

There are 839 mining waste tailings dams in the United States and approximately 3,500 around the world, according the U.S Army Corps of Engineers and the United Nations, respectively. Large dams built to contain mining waste, among the largest structures in the world, must stand in perpetuity. Yet there is no federal agency in the U.S., nor global entity, responsible for oversight of mining waste tailings dam safety. 38 civil society organizations around the world urged the United Nations Environment Programme (UNEP) to push companies and national governments to address the threats mine waste dams pose. UNEP Director Achim Steiner responded with plans to review current guidance and work with stakeholders to examine next steps. Efforts are also underway to pressure US and Canadian governments to take stock of mining waste tailings dams.
