Northwest Pipe to supply pipe for hydroelectric power project in Oregon

VANCOUVER, WA, June 4, 2009 -- Northwest Pipe Company reported today that it has received a Letter of Intent from Slayden Construction Group Inc. of Stayton, Oregon to supply pipe for the Juniper Ridge Hydroelectric Power Project for the Central Oregon Irrigation District.

The Company will supply approximately 14,000 feet of 108" steel pipe valued at approximately $7.0 million for an engineered and custom fabricated piping system. This pipe is expected to be manufactured in the Company's Portland, Oregon facility with delivery scheduled to begin in the third quarter of 2009.

The 3.27 megawatt Juniper Ridge Hydro project is part of the Central Oregon Irrigation District's 22 mile Pilot Butte Canal. The piping portion of the project carries watershed benefits by eliminating water loss through the canal. This loss will place in excess of 20 cubic feet per second of water permanently in the Deschutes River. This additional water will benefit the river habitat and the ESA listed steelhead recently reintroduced downstream. Increased river flows will also enhance water quality conditions of concern to the Department of Environmental Quality under the Clean Water Act.

Northwest Pipe Company manufactures welded steel pipe and other products in two business groups: its Water Transmission Group and its Tubular Products Group.
