Why does the road salt (in the Northeast, anyway) come from far away?

With all these winter storms here in the Northeast (and Midwest and South), I've been hearing a lot about salt supply issues. Supposedly much of it has to come from Chile...but there are plenty of salt mines in North America, aren't there? What about solar evaporation from the ocean right here? Wouldn't such sources save on the costs and environmental impact of shipping long distances? Are domestic sources just exhausted by demand in the Midwest and parts of the South far from ports?
