Explosion at liquified natural gas plant near Tri-Cities injures 4

PLYMOUTH, Wash. (AP) — Authorities say four workers were injured and about 200 residents were evacuated after a large explosion and fire Monday morning at a natural gas processing plant in the eastern Washington town of Plymouth. Benton County Sheriff Steven Keane says the fire from the 8:20 a.m. blast has been put out. He says the explosion sent a mushroom-shaped cloud towering into the air, and shrapnel punctured a liquefied natural gas tank. Some gas leaked but did not ignite. Deputies went door to door throughout Plymouth, along the Columbia River, and evacuated people in a 2-mile radius. Buses were provided for those without cars, and a shelter was set up across the river in Oregon at the Umatilla County Fairgrounds. As part of the evacuation, Highway 14 and railroad tracks were shut down.
