NASHVILLE, Tenn.--(BUSINESS WIRE)--Oct. 22, 2004--Louisiana-Pacific Corporation (LP) (NYSE: LPX) announced today that it will curtail operations at its Woodland, Maine, OSB mill beginning approximately November 8, 2004 due to market conditions and raw material costs. LP will restart the mill if and when market conditions allow. LP intends to operate its Houlton, Maine, OSB mill at normal levels.

"We regret the impact that this curtailment will have on our employees in Woodland and on the surrounding community," said Jeff Wagner, LP's vice president of OSB. "The people at our Woodland mill have done a great job of operating the mill efficiently to combat rising raw materials costs. Unfortunately, continued escalation of raw materials costs coupled with seasonally weaker market conditions made it necessary to make this difficult decision to curtail operations."
