Probably... Read the story here. Problem is, legal agreements made with Flathead County a few years back seem to pave the way for the pit. The Park might have some Clean Air Act claims against the pit and perhaps water rights claims as well. What's really needed is a law that prohibit industrial uses within a certain distance of national parks. A state legislator tried that tact a few years ago, but it failed. Perhaps it could be done on the federal level.
