Lyle Denniston has an excellent post summarizing Grace's petition for certiorari to the Supreme Court over a Ninth Circuit decision on the Libby mine that Grace says obliterates CERCLA's requirement of cost-effectiveness analysis. The government's response is due May 30. (h/t W.W.)

The petition itself is also interesting because it provides a perspective on the infamous Libby, Montana disaster that one hasn't seen in press coverage. If the facts listed are true, then the entire Libby incident was a media-created health scare.
