If you believe all that's in the documentary (and I haven't had the time to follow up), VP Chaney was able to exempt the natural gas drillers from virtually every act ever passed that protects the environment (clean air act, clean water act, etc.). Basically there is no Federal regulation at all and it's left to the states. And as Al said, if the state has only a handful of inspectors for potentially thousands of wells, you can see how we'd loose. Could imagine the impact if the upper buffalo and upper white were contaminated? The environmental/economic impact would be staggering.
