"The two key arguments that the oil and gas industry is using to fight federal regulation of the natural gas drilling process called hydraulic fracturing -- that the costs would cripple their business and that state regulations are already strong -- are challenged by the same data and reports the industry is using to bolster its position.
One widely-referenced study estimated that complying with regulations would cost the oil and gas industry more than $100,000 per gas well. But the figures are based on 10-year-old estimates and list expensive procedures that aren't mentioned in the proposed regulations.
Another report concluded that state regulations for drilling, including fracturing, 'are adequately designed to directly protect water.' But the report reveals that only four states require regulatory approval before hydraulic fracturing begins. It also outlines how requirements for encasing wells in cement -- a practice the author has said is critical to containing hydraulic fracturing fluids and protecting water -- varies from state to state.
One recommendation in that report flies in face of industry's assertion that its processes are safe: hydraulic fracturing needs more study and should be banned in certain cases near sensitive water supplies."
