The Illinois House has approved a measure to regulate high-volume oil and gas drilling in the state.
Lawmakers voted 108-9 Thursday to send to the state Senate a bill outlining rules that energy companies would have to follow during hydraulic fracturing, or "fracking."
Fracking uses high-pressure mixtures of water, sand or gravel and chemicals to crack rock formations deep underground and release oil and natural gas.
Among the measure's requirements is that companies disclose fracking chemicals and test water before and after drilling. It also holds them liable for contamination.
Supporters say fracking would create thousands of jobs in southern Illinois.
Opponents worry it would cause air and water pollution and deplete water resources. They are pushing for a two-year moratorium on drilling.
The bill is SB1715.
