Learn from the Brazil Tailings Dam Tragedy – Act Today to Protect Minnesota

The Vale corporation mine tailings dam disaster in Brazil is another example of the terrible danger posed by the failure of mine tailings waste dams. Now there are 157 people confirmed dead in Minas Gerais, Brazil, with 182 people still missing.


This past fall, Minnesota’s DNR approved PolyMet’s permit for a 252-foot tall earthen dam to contain its copper-nickel tailings. Ask Governor Walz and new DNR Commissioner Strommen to suspend PolyMet dam permits and examine safer tailings waste alternatives.

Environmental group seeks EPA documents on Minnesota Mine, MPR News, February 19, 2019

“WaterLegacy attorney Paula Maccabee has said documents she obtained through an open records request showed regional EPA staffers said last fall they had ‘substantial questions’ about the project, before the Minnesota Pollution Control Agency issued final water and air permits for the mine in December. Maccabee said the EPA never filed formal comments about the project, even though they had expressed a desire to do so.”
