Companies managing large numbers of vehicles and heavy machinery face the potential of surface spills from human or mechanical errors. In the rare instance of a release, Range has engineered safeguards to respond, minimize or eliminate potential impacts. During operations, Range’s shale gas locations are lined with multiple layers of geosynthetic and/or polyethylene liners, similar to the protection at state-of-the-art landfills, as well as engineered berms for added containment. During production, Range employs best practices for the unloading of produced waters and condensate which include spill prevention hose connections.
During each phase of operations, Range is required to develop and implement a Spill Prevention Control and Contingency (SPCC) as well as a Preparedness, Prevention, and Contingency plan (PPC) for each well site. These plans describe measures and actions in the event of a spill. Active well locations with an SPCC have a series of onsite preventative technologies, such as absorbent materials and readily available vacuum trucks to eliminate any spilled liquid beyond the double liner and secondary, bermed containment system. We are currently working with regulators and industry groups to more effectively consolidate and coordinate incident planning.
In 2014, Range managed and handled 78.39 million barrels of fluids in all parts of our operations. The majority of the fluids managed by Range are either produced water or re-use water. While we strive for zero incidents, the company experienced 94 reportable spills, totaling 1,786 barrels or 0.002 percent total fluids handled. None of the spills had a lasting or significant environmental impact, and all spills were immediately reported, addressed and appropriately mitigated.

Range shale well completions use the most environmentally friendly fracturing fluids technically feasible. These are typically composed of 99.9 percent water and sand, with three or four necessary chemical additives, some of which are biodegradable, and all of which are part of everyday life.
