Range utilizes impoundments for the storage and staging of both fresh and reuse water. These impoundments are engineered and constructed to industry leading standards. They utilize such features as perimeter fencing and surface netting in compliance with North American Migratory Bird Treaty Act (NAMBTA) to mitigate wildlife hazards.
Emissions from all sources are assessed and reported on within the federal and state annual reports.
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.
Range follows all applicable regulatory rules as it relates to the careful management of all wastes generated by our operations. Additionally, Range makes all efforts to reduce wastes through active recycling programs Wastes generated from our operations may include: residual wastes, general trash, produced fluids, and drill cuttings. These wastes are routinely tested and characterized for a variety of constituents; including Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM).
Range maintains and implements an internal program for the detection, assessment, and handling of TENORM if encountered in the course of our operations. Any TENORM affected materials are appropriately documented, stored, and transported prior to disposition.
Range was an active participant and contributor to two separate extensive TENORM studies conducted over the past 3 years. For both the Pennsylvania Department of Environmental Protection’s Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) Study and the Industry sponsored MSC, PIOGA Study on Radioactivity Levels in Shale Operations, Range was a significant contributor of site access, samples, and operational information in support of these studies. The top-line finding for both studies found that there is little potential for radiation exposure to workers in the Industry or supporting facilities or the public from shale development in Pennsylvania.
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.
*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.
