A few days ago, Federal Legislation was introduced to regulate Hydraulic Fracturing. Dow Jones Newswire reported:

Industry Warns Bill May Halt Natural Gas Development

U.S. lawmakers Tuesday unveiled a bill that industry warns could prevent development of trillions of cubic feet of natural gas by putting regulation of a key production technique under federal oversight.

It is unclear how much support the proposal could get in Congress or from the White House, but the oil and natural-gas industry has already geared up for a fight to oppose the provision given its potential impact on the sector.

The legislation would repeal an exemption for the process of "hydraulic fracturing" in the Safe Drinking Water Act that requires disclosure of the chemicals used the production process.

By forcing hydraulic water, sand and a small percentage of lubricating chemicals into unconventional types of reservoirs called tight sand and shale gas, companies are able to fracture underground rocks and release the trapped gas not traditionally accessible. States' offices, such as Pennsylvania's Department of Environmental Protection, currently regulate the 60-year-old practice.
