From the Associated Press:
The head of a panel writing rules for fracking in North Carolina says state standards should prevail in any disputes with local governments.
The Fayetteville Observer reported a study group of the North Carolina Mining and Energy Commission met Friday in Pittsboro. Commission chairman and Lee County Commissioner Jim Womack says local governments should have to prove why they want their rules to be more stringent than any state standards.
Fracking is a type horizontal drilling that uses chemicals, sand and water to release natural gas from rock formations. Scientists think Lee and nearby counties may hold large deposits of the gas
Fracking opponents are concerned about possible harm to people and the environment. Supporters say fracking will bring a much-needed economic boost.
