Calgon Carbon Responds To Supreme Court's Decision To Overturn MATS (Mercury And Air Toxics Standards) Rule For Power Plants

PITTSBURGH, PA  –  06/29/2015

Calgon Carbon Corporation (NYSE: CCC) responds to today’s ruling by the United States Supreme Court, which overturned the U.S. EPA’s MATS rule. The MATS rule would have represented the first national standard for the reduction of power plant emissions of mercury and other air toxins. As a result of regulations already in place in certain states and in Canada, many power plants are already investing in solutions that utilize powdered activated carbon to reduce mercury emissions.

“We knew this decision could go either way; and while it is disappointing, there are mercury control regulations in place in many states and Canada that have already established a sizable market. We continue to expect to increase our activated carbon mercury removal market revenues by approximately 50% this year,” said Randy Dearth, Chairman, President and CEO of Calgon Carbon Corporation.

The Company estimates the size of the current market to control power plant mercury emissions created by certain state and Canadian regulations to be in the range of 120 million to 160 million pounds of powdered activated carbon per year (as measured in standard first generation product quantities). To serve this market, Calgon Carbon offers three generations of carbon for coal-fired power plants, under the brand name FLUEPAC^® activated carbon, representing eight years of R&D and roughly 75 full-scale trials.

Looking beyond the mercury removal market, which represented approximately 5% of Calgon Carbon’s total sales in 2014, the company continues to focus on other near- and long-term revenue growth drivers. These include growing outsourced activated carbon distribution activities outside the United States, the impact of adding capacity through previously announced plant efficiency and expansion projects, converting North American municipal water customers to activated carbon and reactivation solutions, capitalizing on the emerging ballast water treatment equipment retrofit market, expanding the company’s reach into new geographies including Latin America and India, and executing strategic business acquisitions.
