Calgon Carbon Announces Three Multi-Year Powdered Activated Carbon Supply Agreements for Mercury Removal with New and Existing Customers

PITTSBURGH, PA  –  10/05/2015

• Exclusive, Requirements-Based Agreements Cover 19 Coal-Fired Generating Units at Nine Facilities
• Annualized Revenues under the Agreements Expected to Approximate $20 million
• Includes Supply of Next Generation FLUEPAC® Product Solutions

Calgon Carbon Corporation (NYSE: CCC) (CCC or the Company) today announced the recent finalization of three, multi-year supply agreements with major U.S. power generators whereby Calgon Carbon will supply a combination of standard and advanced powdered activated carbon products to remove mercury from the flue gas of 19 coal-fired power plant generating units, at nine different facilities.

These exclusive, requirements-based supply agreements relate to the supply of eight facilities that are continuing to control mercury emissions as a result of State-level regulations, and one facility that is currently controlling mercury emissions under the Mercury and Air Toxics Standards rule. Annualized revenues under the three agreements are expected to total approximately $20 million.

Two of the agreements, which run through December 2017, represent renewals of previous multi-year customer supply agreements – one of which has been enhanced to include the supply of powdered activated carbon to five additional generating units. The third agreement, which runs through September 2018, is with a new customer and calls for Calgon Carbon to supply six additional generating units. Calgon Carbon began supplying product to a majority of these additional generating units in the spring of this year.

Of particular note, the agreements call for Calgon Carbon to supply FLUEPAC^® STF or FLUEPAC^® SF3 powdered activated carbon products for mercury removal at 11 generating units. The selection of these third generation mercury removal products was primarily based upon the completion of full-scale product trials.

”I’m extremely pleased to announce the signing of these long-term supply agreements that extend and enhance existing relationships, and forge the beginning of a new one, as we continue to work closely with our customers to meet their ongoing mercury control requirements,” said Bill Zinsser, Vice President of Specialty Products, Calgon Carbon Corporation. “These agreements also serve to validate the significant investments made by Calgon Carbon over the last seven years to develop advanced powdered activated carbon solutions. As a result, our diverse product line enables customers to independently test – and ultimately select – an optimal solution set of Calgon Carbon products to meet the unique mercury control needs of each individual coal-fired generating unit, and achieve the lowest total cost of mercury control.”

Calgon Carbon continues to expect its 2015 full year revenues related to its powdered activated carbon products for mercury control to total $55 million to $60 million.

FLUEPAC^® STF is an advanced product that allows for superior mercury removal performance in situations where dry sorbent injection is also being utilized by the power plant for the removal of sulfur dioxide (SO₂). FLUEPAC^® STF permits the use of up to 90% less activated carbon than first generation product solutions when activated carbon is used in combination with dry sorbent injection.

FLUEPAC^® SF3 is an advanced product that allows for superior mercury removal performance in situations where sulfur trioxide (SO₃) injection is also being utilized by the power plant for flue gas conditioning to improve particulate capture in the electrostatic precipitator. FLUEPAC^® SF3 permits the use of up to 70% less activated carbon than first generation products when SO₃ injection is utilized, which contributes to its concrete friendly nature, and provides the customer with the additional benefit of continued fly ash sales.
