The raw natural history data Pebble recently dumped told us nothing about risk, was meaningless and a waste of our time and its money. The timid EPA effort was similarly useless. And Keystone? Read its report about the OK Tedi mine disaster, and then read about the successful Australian civil action against the mine.
The risks are innumerable. Earthquake. Severe weather. Tailings dams fail. Pipelines rupture. Acid mine drainage is not always contained. Cyanide will be used. Mercury will be released from gold roasting and contaminate downwind streams. There will be accidents like a truckload of cyanide into a creek. There will be spills at the port. Culverts will be blocked. Mining is messy.
