NEW YORK ( TheStreet) -- New York Attorney General Eric Schneiderman filed a lawsuit on Tuesday against the federal government to stop the development of natural gas drilling in the Delaware River Basin. The New York Attorney General's suit alleges that the federal government didn't perform a required full environmental review of proposed natural gas drilling regulations, including fracking regulations, for the Delaware River Basin. The fracking technique is a high-pressure method of horizontal drilling that pumps a combination of water, sand and chemicals into shale to create fractures and allow natural gas to be collected at the surface. The potential environmental risks poed by the chemicals used in the process have never been disclosed by the natural gas industry, though pressure is mounting on the industry to deal directly with the fracking disclosure issue. The fracking chemicals have come under attack for their potential to cause widespread harm to the environment and human health, a case made most publicly in the Academy Award-winning documentary, Gasland. Fracking uses clean water, and critics contend, puts that water back into the aquifer in a polluted form through its pressure pumping technology. Chesapeake Energy ( CHK) is the largest leaseholders in the Marcellus Shale (which runs beneath a significant portion of the Delaware River Basin). Chesapeake Energy describes the fracking process in a fact sheet posted on its web site in April as being "99% water and sand, with a small amount of special-purpose additives." Chesapeake includes a long list of special-purpose additives which it says are common ingredients in consumer products, including in glass cleaner. The Delaware River Basin Commission (DRBC), a federal-interstate commission with authority to take actions that may impact water resources and approved a drilling plan for the Delaware River Basin, estimates that its proposed regulations would allow 15,000 to 18,000 gas wells to be drilled within the Basin, most of which are expected to be developed by fracking. The filing of the lawsuit comes one month after New York Attorney General Schneiderman told the federal government he would take legal action if the government didn't conduct a more comprehensive environmental review. "Before any decisions on drilling are made, it is our responsibility to follow the facts and understand the public health and safety effects posed by potential natural gas development," Attorney General Schneiderman said in a release. Schneiderman's office said in a release that even after federal agencies determined that natural gas drilling in the Basin would potentially result in significant environmental impacts and that the study of those impacts should be performed, the U.S. Army Corps of Engineers made clear last week that it would make no such commitment. The NY Attorney General claims that the National Environmental Policy Act mandates a full review of the impact of the proposed natural gas development regulations.
