Susan Cooke was quoted in a SNL Financial podcast (April 6) regarding hydraulic fracturing technology that captures oil and natural gas below ground and below water aquifers. Fracking has been used for decades, but new techniques may require up to five times more chemicals and fluids than vertical drilling, raising environmental concerns. The EPA will study potential adverse effects of the new process, and, although bills to regulate it have been introduced into Congress, Ms. Cooke does not expect action until the EPA releases its findings. "My guess is that the bills are going to languish, partly because of the attention given to health care legislation and to other important programs, while EPA gears up to begin their study," she said. "While some of the proponents of the legislation want to get them passed even before that study is completed, others may be more willing to allow them to languish...until such time that the study is under way, if not finished."
