Water responsibility starts with us.

CONSOL Energy recognizes the inherent value of water resources and continues to focus on the responsible use and protection of this valuable natural resource for the benefit of all stakeholders.

Water Management

CONSOL recognizes the inherent value of water and continues to focus on the responsible use and protection of this valuable natural resource for the benefit of all stakeholders. In 2015, CNX Water Assets LLC strengthened its commitment to provide water-related services to operations in a safe and environmentally responsible manner. As part of this effort, we continue to evaluate emerging treatment technologies and champion the reuse of treated mine water for shale gas development. These activities support our strategic vision of water asset management, where the innovative use of existing water assets not only maintains the highest standards of environmental protection, but also creates value for the company.

Our water assets provide the company with significant operational benefits and business opportunities. For the third year in a row, the Water Assets increased third-party water use and sharing agreements with third party consumers. This has the benefit of reducing the footprint of shale gas related water infrastructure and the need for trucking water, while responsibly utilizing approved resources. We continued to pursue water treatment and reuse technologies including the potential for beneficial use of byproducts resulting from water treatment, all of which can positively impact water asset management and financial performance.

In support of our natural gas and coal mining operations, CONSOL operates 55 waste water treatment plants. The treatment plants cover a wide spectrum of treatment technologies from passive biological systems, to conventional sewage and acid mine drainage treatment, to an industry leading state-of-the-art zero liquid waste (ZLW) facility. These facilities are designed, maintained and operated in compliance with the stringent permit conditions, ensuring that discharges from ongoing operations do not negatively affect the environment.

From an operational perspective, we continue to focus on three key areas of water resource management: minimizing impacts to local water resources, maximizing recycling of process waters, and championing the use of treated mine water (i.e. mine influenced water (MIW) as a first-run feedstock for third party consumption).

Continuing our efforts to improve the water quality of streams and rivers and protect aquatic habitats, CONSOL continues to operate many of its legacy mine water treatment facilities through a managed discharge approach, such that they do not discharge treated water during low flow periods of the year when natural recharge from rainfall is limited and streams may be stressed by consumptive and industrial demands. This is now a standard operating procedure for these facilities and one that will continue into the foreseeable future.

CONSOL has expanded on the effort to reduce our water footprint by initiating a series of hydrogeological studies of the legacy mines in order to more fully assess potential improvements to the management of the mine pools with respect to both the quantity and quality of the water currently being treated.

Our Performance in 2015

CONSOL uses the following metrics and information to track water management performance for our gas and operations:

In evaluating the water use in our gas operations, the differences in totals year-over-year are directly attributed to the growth of our E&P segment. As a result of our managements' appropriate response to market conditions, less water was consumed as a whole, coupled with a proportionately larger volume of water being recycled due to decreased drilling activity combined with effective reuse and recycle policies. In evaluating water use trends of our coal operations, the decrease in the total volume consumed was related to a decrease in coal production driven by market conditions and the resulting reduction in freshwater consumption along with process improvements at our mining operations. This resulted in a measured decrease in total water consumption. Recycled volumes were also negatively impacted by the decreased production at our Pennsylvania and Central Appalachia complexes. We have water re-use systems in place at our coal preparation plants, incorporating pump-back from our slurry impoundments to our prep plants.

Continued Reduction of Our Water Footprint

The water footprint of a business is defined as the total volume of freshwater used to produce the goods. Water use is measured in water volume consumed and/or polluted per unit of time. As detailed above, CONSOL is actively involved in reducing the amount of freshwater used in its operations by emphasizing the recycling of waters produced by our gas production and coal mining activities.

In addition to these efforts, CONSOL is focused on surface mine reclamation efforts, designed to allow for an expeditious return of these sites to a condition in which rainwater runoff from these sites is effectively un-impacted by the previous mining activities and can be allowed to flow into receiving streams without treatment.
