I suspect a lot of readers have followed the story of Libby, MT, since the Seattle Post-Intelligencer first reported, nearly 10 years ago now, on the epic asbestos pollution there by the notorious corporate polluter W.R. Grace and its predecessor. So I wanted to flag that the EPA yesterday declared a public health emergency in Libby, the first time the EPA has invoked that provision of the Superfund law since it was passed in 1980. Too late for the more than 200 people who have died there.
