Washington Post: In response to a petition filed by Earthjustice, a nonprofit group dedicated to the environment, the US Environmental Protection Agency will gather public comment on whether fracking companies should be required to disclose information on the chemicals they use. Hydraulic fracturing involves the injection of a mixture of liquid, sand, and chemicals into a wellbore to fracture the surrounding rock and allow gas or oil to flow to the well. Until now, fracking has been regulated by the individual states, only a few of which require any kind of disclosure. Although drilling companies have been reluctant to reveal industry secrets to their competitors, mounting environmental concerns, such as contamination of local drinking water, are driving the push for federal regulation.
