A Responsible Care® re-verification for Canada Colors and Chemicals Limited and Sulco Chemicals
Limited (CCC/Sulco) was carried out on November 6 and 7, 2006 by a three-member Canadian
Chemical Producers’ Association (CCPA) appointed Team and on November 9 and 13, 2006 by the
team leader, augmented by a local community representative in the communities visited.

Based upon a comprehensive review of Canadian National Railway operations,
the re-verification team is satisfied that the company’s decision-making and
actions are in alignment with the principles of the Responsible Care ethic, and
that the overall management system is self-healing (i.e., based on a process of
continual performance improvement, and identification and timely correction of
deficiencies).

The former Witco Canada Inc., located in West Hill Ontario, is a long standing member of CCPA.
The company underwent their initial or “In-Place” verification in 1996, and their first reverification in
September 2000. The company has changed ownership and name several times since their “In-Place”
verification. In 1996 Crompton Knowles purchased Uniroyal Co. and in 1999 merged with Witco
Corp. to form C. K. Witco that then became Crompton Corp.

Based upon a comprehensive review of Canadian Pacific Railway operations,
the re-verification team is satisfied that the company’s decision-making and
actions are underpinned by the Responsible Care ethic, and that the overall
management system is self-healing (i.e., based on a process of continual
performance improvement, and identification and timely correction of
deficiencies).
