Extensive Water Treatment CONSOL treats over 36 billion gallons of mine water annually and manages over 97 billion gallons of water Operate 103 waste water treatment plants Currently operate one Reverse Osmosis ZLD plant and commissioning another that will start up in May 2013 to treat mine water Operate several passive as well as active selenium treatment systems Evaluating unique systems such as floating wetlands that could be adapted for use at our sites In 2011, CONSOL had total withdrawals for its mining operations of 25.3 billion gallons of water We recycled and re-used 26% of that demand For CONSOL’s gas segment, we had a total demand of 0.2 billion gallons of water We recycled and re-used 31% of that demand

CONSOL’s Focus on Technology  Must be a clear fit within our core operations  Generally interested in emerging technologies that are ready for field demonstration  Considering some limited equity investment
