I don't blame him for working for the EPA -- somebody has to play watchdog.  He had better watch his ethics a little closer though.  6 words can be looked at as "advising".  His lawyer obviously could contact him and he obviously didn't want to respond.  Now that he's needing money, he wants to get a job.  The EPA will probably hire him because he's proven himself.
Bristol Bay a National Park?? Would that eliminate fishing entirely?  After all, you can't hunt in Yosemite without special permission!  From what little I know about Park laws, that permission has only been given a few times.  What would that do to the fishing industry?  I believe there is a national act that puts mining as the primary use of national land and has not been modified to change that.  So how does a designated mining area become a fishing protectorate?
I still say, buy the corporation(s) and eliminate the mine!
