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.
