Temiscaming, Quebec, Canada 17 September 2008 – Tembec today announced a one-week production curtailment at its Matane, Quebec, pulp mill to balance inventory levels. The Matane hardwood high-yield pulp mill will stop production on 21 September and will resume production on 28 September. This will result in approximately 5000 metric tons of product not being produced. The company will take advantage of this temporary shutdown to conduct maintenance work.

“This latest production curtailment follows recent announcements related to our Temcell and Tarascon pulp operations and is intended to prudently manage both inventory levels and working capital," said Yvon Pelletier, executive vice president and president of the Pulp Group. "This decision comes amidst declining pulp demand in Europe and Asia, prime markets for our Matane pulp mill. The shutdowns announced to date will reduce our total annual production by 21,500 [metric tons],” he said.

Management has informed employees of the company’s decision. The shutdown will affect roughly 60 employees out of the mill's total workforce of 120.

The Matane mill has an annual production of 250,000 metric tons of hardwood high-yield pulp.
