From an email from one of our law profs at UB:
Every mine disaster is followed by a report of the violations previously found at that mine. The maximum fine for the failure to eliminate violations that actually cause death or serious injury is $60,000. Fines are generally reduced by the agency and many are simply not collected. If the new Senate bill passes, the cost of uttering an obscene word on the airwaves will be worth over 5 times the value of miners.
