Therefore, regardless of if a waste exhibits hazardous characteristics, wastewater including flowback, from oil and gas wells is exempt from the “cradle to grave” provisions under RCRA. Other wastes generated from activities other than the well or field operations may be regulated as hazardous, such as unused fracturing fluids or acids, waste solvents, painting wastes, and oil and gas service wastes.

Hydraulic ,fracturing,, also known as fracking, is a method of oil and natural gas extraction.The process involves injecting ,fluid, into subterranean rock formations at high pressure. The high-pressure ,fluid, produces a fracture network that allows crude oil and natural gas inside dense rocks to flow into a wellbore and be extracted at the surface. The ,fluid, (known as frac ,fluid,) contains between ...

Hydraulic ,fracturing, for natural gas extn. from shale produces ,waste, brine known as ,flowback, that is impounded at the surface prior to reuse and/or disposal. During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compds., and result in biocorrosion that complicates water and ,waste, management and increases prodn. costs.

Some drilling operators elect to re-use a portion of the wastewater to replace and/or supplement fresh water in formulating ,fracturing fluid, for a future well or re-,fracturing, the same well. Re-use of shale gas wastewater is, in part, dependent on the levels of pollutants in the wastewater and the proximity of other ,fracturing, sites that might re-use the wastewater.
