Ultraviolet Light Technology

• Drinking Water Disinfection• Inactivation of

• Wastewater Disinfection

• UV Oxidation• Taste and Odor• Remediation

13

UV – Becoming a Leader in a Rapidly Growing Market

● UV Light for Drinking Water and Wastewater Disinfection● $3-billion market over six years● Complete product lines for drinking water and

wastewater disinfection● Drinking Water Disinfection

● CCC invented UV process for prevention of infection from

● Sentinel® reactors (installed and sold) to treat 1.2 bgd

● Wastewater Disinfection● Launched C3 Product line in 2004 and 2005

Modular, open channelLow pressure, high output lampsAutomatic cleaning systemTreating more than 55 mgd

● Expect growth rates in excess of 25% per year

14

CCC Re-engineered in 2005-2006

● Offset $30M in cost increases● Changed commercial asset and logistical strategies in Carbon and Service

● Raised prices● Exited low margin sub-segments● Optimized asset utilization● Optimized supply chain

● Simplified Company to increase focus on core. Divested non-core businesses (i.e. Charcoal and Solvent Recovery)

● Changed equipment philosophy● Reduced headcount and fringes, including U.S. pension freeze● Optimized logistics and production planning● Closed Japanese Joint Venture plant● Implemented capital improvements – Example: Energy conservation● Implemented new credit structure – lower cost, more capacity

15

Legal Expense Had Significant Impact on 2005-2006 Results

● Legal Expense has been concentrated in three areas:● UV Patent Defense● 1996 Acquisition Suit ($10M Award)● Anti-Dumping Tariff Petition

● Progress made in recent months ● 2007 expenses will sharply decline

Tariffs on Chinese Carbon Represent Major Opportunity for CCC

Anti-Dumping Petition Filed (Chinese activated carbon imports to U.S. approximate 80MM lbs./yr.)

Tariffs Signal Fundamental Change in Carbon Industry

● Final tariffs set at 62% to 228%● Importers must post bond or cash deposit equal to

amount of tariff● Majority of Chinese imports to U.S. subject to tariffs of

73.6%● CCC subject to tariffs as Importer● Effect of tariffs (example)

● Average cost Chinese carbon $0.30/lb.● Tariff @ 70% x 0.70

$0.21/lb.● Cost of Chinese Carbon = $0.51/lb. vs. $0.30/lb.● Tariffs should result in Fair Market Pricing in U.S.

18

Mercury Removal – Potentially Largest Market Ever for Activated Carbon

• Mercury Removal From Power Plant Flue Gas• CAMR regulations set 70% reduction by 2010• Further reduction of 90% by 2018

• Several states increasing reductions and/or expediting compliance

• New plants subject to regulated levels upon start-up

19

U.S. Market Potential $100MM - $500MM per Year

• Injection of Powdered Activated Carbon is leading abatement technology

• CCC Product Family for Enhanced Mercury Removal• FLUEPAC MC – participate in early bulk market• FLUEPAC MC PLUS – enhanced value for increased removal• FLUEPAC MC derivatives – Value added proprietary position for

niches• Equipment Line – facilitate storage and handling

• Action Plan• Product testing top priority

• State-specific activity for improved response to specific coal types• Expand production capacity and efficiency• New starting materials to respond to increased demand or

performance requirements

20

Other Growth Opportunities

● Stage 2 Disinfection By-Product Rule● 600+ new granular activated carbon systems

expected● MtBE Remediation

● $2 to 12B Market● Perchlorate Removal from Groundwater

● $1B Market, 28 states● Launching new patented technology● Regional Service expansion

21

Formula For Success

● Fundamental Change in Industry (Tariffs)

● Firm Foundation in Place (Re-engineering)

● Biggest and Most Growth Opportunities ever with CCC Products perfectly positioned
