The Bonneville Power Administration welcomed a couple of hundred people at Castle Rock Elementary School yesterday, as the power agency opens a series of public meetings on the I-5 Corridor Reinforcement Project, a proposal to build a 500-kilovolt transmission line between Castle Rock and Troutdale. One topic of discussion was the so-called “Pearl Route,” which the Cowlitz County Commissioners are looking at for reconsideration. Doug Johnson with the BPA says that the “Pearl Route” was rejected because of potential high costs and environmental impacts. Johnson says that the BPA is going out with revised route maps, showing how several possible segments have been removed, moving them away from populated areas. He says that they’re also looking at moving the north-end substation to a site that’s further north and east of Castle Rock. Johnson says that the agency is still on track for the project, using this year to develop preliminary design and documentation of project impacts. They’re still planning to come out with its draft environmental impact statement on the project in fall of next year. Additional public meetings are planned for today at Skyview High School, on the 8th in Amboy, and on the 12th at Union High School. Additional information is available on the BPA website.
