"On April 7, 2016, the Environmental Protection Agency proposed adding the ""Bonita Peak Mining District"" to the National Priorities List, making it eligible for Superfund. Forty-eight mine portals and tailings piles are ""under consideration"" to be included. The Gold King Mine will almost certainly be on the final list, as will the nearby American Tunnel. The Mayflower Mill #4 tailings repository, just outside Silverton, is another likely candidate, given that it appears to be leaching large quantities of metals into the Animas River. What Superfund will entail for the area beyond that, and when the actual cleanup will begin, remains unclear. Eric Baker"
