Siren tests to be prepared for a possible emergency at the Energy Northwest nuclear power plant near Richland are planned from 10 a.m. to noon Wednesday.
Sirens will sound along the Columbia and Yakima rivers. They may be heard between the Vernita Bridge and Leslie Groves Park in Richland, at the Horn Rapids Off-Road Vehicle Park, the firing range on Horn Road and the Columbia Generating Station.
Sirens will sound several times, with each test preceded and followed by voice announcements that a test is being conducted.
