This was the second reverification of RohMax Canada (the previous
reverification was in 2002). The team visited the sole RohMax Canada site
in May, 2005.

Upon the completion of three days of interviews with global managers, country
specific managers, employees and appropriate stakeholders the reverification
team judges Nalco to have a very good understanding of the Responsible Care®
codes and have integrated these codes with the appropriate company
management systems. The Responsible Care® ethic is well understood at all
levels and is part of day-to-day management of the global corporation.

A Responsible Care® re-verification for Degussa Canada Inc.’s Gibbons,
Alberta, was carried out on April 26th and 27th, 2005 by a three-member
Canadian Chemical Producers’ Association (CCPA) appointed Team,
augmented by a local community representative.

This reverification team found that the Responsible Care ethic as it pertains to internal environmental,
health and safety issues is well understood and entrenched in the company’s EH&S management system.
To a very large degree it guides the daily actions and decisions of the company’s management team and
its employees. It is the company’s externalization of Responsible Care, the “Being Seen To Be Doing
The Right Thing”, that gives the team concern. We do, as always, also see opportunities for
improvement elsewhere in the company’s management system. These will also be mentioned in the text
of the report.

On Tuesday April 11, 2005 two reverification team members met with the
Ashland Canada Corp. Vice-President Faisal Zekry and Responsible Care®
coordinator David Kim to review the status of the findings requiring action from
the January 2001 report and subsequent return visit reports.
