The Texas Railroad Commission (RRC) has issued a proposed rule that would allow the recycling of hydraulic-fracturing fluids and reuse of water produced in oil and gas drilling. Under the proposed rule, companies could recycle water and “hydraulic fracturing flowback fluid” on site without a permit. “Flowback” describes the initial water that returns to the surface during the hydraulicfracturing process. These fluids, as well as produced water, are normally kept in storage tanks or containment pits until disposal, which usually involves injecting them deep underground. RRC will accept comments on the proposed rules for 30 days. See the Texas Register, September 28, 2012.
