Two Years Later, a Look at Mount Polley

August 3, 2016 • Shreema Mehta

On August 4, 2014, a mine waste dam in British Columbia, Canada breached, releasing 24.4 million cubic meters of mine waste (or tailings) sludge into the Fraser River watershed, a group of lakes and rivers that bear salmon and sustain the livelihoods of local First Nation communities.

New Analysis: Ignoring best practices, four BC/Alaska transboundary mines risk repeating Mount Polley disaster

March 22, 2016 • Earthworks | MiningWatch Canada | Rivers Without Borders

In the midst of deliberations over the British Columbia Mining Code, an international coalition today released, Post-Mount Polley: Tailings Dam Safety in British Columbia, a new analysis revealing that four major BC mine projects in the Alaska/British Columbia transboundary region fail to implement the recommendations of the Mount Polley expert panel, risking similar mine waste containment disasters. The Mount Polley mine disaster, considered the worst mine disaster in Canadian history, occurred in August 2014, releasing over 25 million cubic meters of mine waste into the Fraser River watershed.

UNEP must act to avoid mine waste disasters

August 31, 2015 • Shreema Mehta

One year ago in August, a mine waste dam failed. The breach sent 24.4 million cubic meters of a liquefied mixture of toxic heavy metals and other chemicals into the Fraser River watershed in British Columbia, Canada. To help prevent further toxic catastrophes, over 3 dozen environmental and social justice groups including Earthworks, Friends of the Earth, and Greenpeace sent a letter today to the United Nations Environment Programme urging the agency to call for global review and regulations to address threats posed by similar dams at existing and proposed mines around the world. As the global authority on environmental protection, UNEP can not only bring much-needed attention to this problem, but also develop international guidelines and assist countries to respond to this growing threat.

Washington, D.C., Dillingham, AK -- In response to the findings of an investigation of the Mount Polley tailings dam failure in British Columbia, Canada, a coalition of environmental and community groups today called upon the U.S. Environmental Protection Agency (EPA) and the United Nations Environmental Programme (UNEP) to investigate threats posed by similar mine waste dams in the U.S. and around the world, and to reassess existing mine proposals.

Seabridge Gold’s KSM Mine Proposal Poses Significant Risks

November 12, 2014

WASHINGTON, DC—A report released today identifies significant risks associated with the Kerr-Sulphurets-Mitchell (KSM) mine proposed by Seabridge Gold in northwest British Columbia near the border with Alaska and upstream of Misty Fjords National Monument. It details a growing list of operational, legal, economic and political challenges facing the controversial project, which some analysts have compared to the proposed Pebble Mine in southwest Alaska.
