A new year means new rules take effect and that is exactly what happened in Oklahoma when it comes to fracking chemicals.
The rule requires all oil and gas well operators in the state to report the chemicals used in hydraulic fracturing. Previously, only operators of horizontal drilling wells had to disclose fracking chemicals. That rule took effect at the beginning of 2013. This new rule is an extension to that.
Operators must report fracking chemicals to FracFocus.org, or to the Oklahoma Corporation Commission, which will add the information to FracFocus.org on behalf of the operator. FracFocus.org went live in 2011, and many operators began voluntarily reporting chemical makeup at that time.
Hydraulic fracturing remains a controversial topic with the public because of the chemicals involved in the process.
Although most operators maintain the bulk (typically 99 percent) of fracking fluid is made of water and sand, the remaining chemical composition has been the target of repeated inquiry.
