NID utilizes patented technology, developed and proven by Newpark for managing RCRA-exempt oilfield wastes, to process nonhazardous industrial wastes into a water-based fluid that is directly injected into NID’s Class I UIC well(s) located in the Big Hill field.

A totally-contained, above-ground facility processes solid and semi-solid nonhazardous wastes in eleven (11) TNRCC-permitted waste management units to generate this stable, injectable fluid.

The individual WMU’s that comprise the Big Hill processing facility are listed below: WMU No. 1: Bulk solid waste tank WMU No. 2: Bulk liquid waste tank WMU No. 3: Bulk liquid waste tank WMU No. 4: Stormwater tank WMU No. 5: Stormwater tank WMU No. 6: Container storage area WMU No. 7: Washout/decontamination area WMU No. 8: Waste processing area WMU No. 9: Waste neutralization tank WMU No. 10: Waste mixing/treating tank WMU No. 11: Waste mixing/treating tank

Processing of solid and semi-solid wastes is achieved through Newpark’s six-step method, which includes waste slurrification, particle-size reduction, liquification, viscosification, rheologic enhancement, and final testing of the injectable fluid. Liquid industrial wastes not requiring processing are received and directly injected into NID’s Class I UIC wells.

NID’s Big Hill facility processes and injects a variety of nonhazardous industrial wastes, including aqueous liquids, water-soluble wastes, wastewater treatment sludges, storage tank sediments, byproducts and wastes from industrial processes, and contaminated soils and media.
