Federal Way, Washington, USA, 08 July 2008 — Weyerhaeuser Company (NYSE: WY) announced today that it will permanently close its idled Structurwood mill in Drayton Valley, Alberta, Canada.

The oriented strand board mill has not been in operation since December 2007.

“Factors that led to the original decision to idle the Drayton Valley Structurwood mill – the decline in the U.S. housing market and the high Canadian dollar – have not changed since that decision,” said Phil Dennett, vice president, Strand Technologies for Weyerhaeuser.

When operations were indefinitely curtailed in December 2007, about 130 people were employed at the mill. A number of people moved to other Weyerhaeuser operations, including many to the softwood lumber sawmill on the same site. Others received severance.

Weyerhaeuser’s dimensional softwood lumber sawmill in Drayton Valley continues to operate.

“Weyerhaeuser is working with the Government of Alberta to find ways to enhance the viability of our remaining mills in the region, both the sawmill in Drayton Valley and the Structurwood mill in Edson,” said Dennett. “We are hopeful those discussions will result in long-term fibre security not only for those facilities but for other forest-related opportunities in the region.”

Dennett also said Weyerhaeuser is committed to working with the Town of Drayton Valley to as it explores ways to broaden the community’s economic base.
