PacifiCorp to dismantle Condit Dam

PacifiCorp (NASDAQ: PPWRM) said removal of the 14.7 MW Condit Dam on the White Salmon River in south central Washington will begin this fall, fulfilling a multi-party settlement agreement signed in 1999.

The $32 million decommissioning project is moving forward following receipt of a sediment management permit from the U.S. Army Corps of Engineers, the final major regulatory step. In December, PacifiCorp received a Surrender Order from the Federal Energy Regulatory Commission providing for dam decommissioning. FERC modified the order in April which, with the Corps permit, gives PacifiCorp the regulatory certainty needed to proceed
with the dam removal.

PacifiCorp determined it was less costly to remove the dam than to install a fish passage system that would be required as part of the federal dam relicensing process. JR Merit Industrial Contractors Inc. will be the construction contractor, while Kleinfelder will provide engineering and construction monitoring services.

Plans call for preparation during the summer before a planned breach in October releases a lake through a 13-foot hole near the base of the dam. After the initial breach and draining of the reservoir, demolition of the remaining portion of the dam is scheduled to begin in spring 2012 and be completed by August 2012.
