Business Editors/Environment Writers

HUDSON BAY, Saskatchewan--(BUSINESS WIRE)--Feb. 12, 2003

Weyerhaeuser Company's (NYSE:WY)(TSE:WYL)Hudson Bay oriented strand board mill has earned international recognition for its rigorous approach to environmental management.

The facility is registered to the ISO 14001 environmental management system standard. Certification followed a thorough independent audit by NSF International Strategic Registrations Ltd.

Established by the International Organization for Standardization, headquartered in Switzerland, ISO 14001 registration recognizes organizations whose environmental management systems meet the comprehensive requirements of this internationally recognized standard.

"Preparing for the ISO 14001 standard was an enormous effort involving the entire staff," said Bob Batt, unit general manager of Weyerhaeuser's Hudson Bay operations. "However, there will be many benefits from this effort, the foremost of which will be better management of the environmental aspects of our mill activities, products and services," he added.

In order to achieve ISO 14001 certification, Hudson Bay OSB developed and implemented a formal, documented environmental management system. That system addresses both environmental regulatory compliance and internal processes aimed at reducing waste and preventing pollution.

"We are very pleased to receive this important industry certification," said Batt. He called the certification an example of the commitment at the Hudson Bay mill to operate in accordance with the highest environmental standards.

Batt said the mill Enviro Team 2000, headed by Environmental Manager Kevin Crittenden, worked diligently to prepare for the certification audit.

"The professionalism of our employees is the key to the implementation of these management systems and our continued success," said Batt.

The Hudson Bay mill is the 19th Weyerhaeuser manufacturing facility to earn ISO 14001 registration. In addition, more than 80 per cent of Weyerhaeuser's forest lands are ISO 14001 registered, including the Pasquia Porcupine and Prince Albert Forest Management Areas in Saskatchewan.

The Hudson Bay mill employs approximately 200 people and produces oriented strand board (OSB). OSB is a construction panel made with layers of precision-manufactured wood "strands" that are aligned, formed into panels and pressed with an exterior grade adhesive resin.
