Heres a good reason for the delay tactics:
This kind of mining has never happened in Minnesota before, but in other states, it is associated with long-lasting water pollutionNo sulfide mine has ever operated without polluting its nearby watersThe EPA identifies the hardrock mining industry (sulfide mining is a type of hardrock mining) as the largest toxic-waste producing industry in the U.S.The sulfide ores that are excavated react with oxygen in the air and water from rain and other precipitation – and form sulfuric acid. This acid is harmful to organisms that live in water (fish, invertebrates, etc). It also leaches out toxic heavy metals in the rocks with which it comes in contact – metals harmful to people and to wildlife. This polluted discharge is often called “acid mine drainage,” and it can persist for hundreds, even thousands, of yearsThe sulfide mining industry also has a long track record of financial irresponsibility. Many companies go bankrupt or fail to provide enough “financial assurance” – a damage deposit up front – to cover the costs of dealing with pollution. This has left some states and their taxpayers with hundreds of millions of dollars in liability
