Government auditors say federal officials know nothing about thousands of miles of pipelines that carry natural gas released through FRACKING, and need to step up oversight to make sure they are running safely.

Fracking describes the process of drilling down and creating tiny explosions deep underground to shatter and crack hard shale rocks to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure. This allows the gas to flow out to the head of the well. The process is carried out vertically or, more commonly, by drilling horizontally to the rock layer. The process can create new pathways to release gas or can be used to extend existing channels.
The term is short for hydraulic fracturing and refers to how the rock is fractured apart by the high pressure mixture. Experts also refer to a "frac job" and a "frac unit."
Fracking has become controversial in some countries. Much of the water used in fracking is collected from the well and processed, but there are concerns that potentially carcinogenic chemicals can sometimes escape and find their way into drinking water sources.
Some American householders also claim that shale gas leaking into their drinking supply causes tap water to ignite. The industry itself also vigorously denies that shale gas is unsafe and blames pollution incidents as examples of bad practice, rather than an inherently risky technique.
An independent geological report found it "highly probable" that fracking triggered two minor earthquakes on the Lancashire coast of England in 2011. The energy company Cuadrilla - which suspended its fracking test operations in June following the tremors - said the conditions that caused them are unlikely to occur again.
