Trailer wreck closed 270 for hours By Heather Ratcliffe and Sara Shipley Of the Post-Dispatch 08/10/2004 A semi-tractor tank truck overturned about 3 a.m. today, blocking both directions on Interstate 270 near Lilac Avenue in north St. Louis County. Crews worked through rush hour traffic to clean the ethanol that leaked from the tank. At about 1:30 p.m., it appeared that all lanes of westbound I-270 had been reopened except the right lane. Eastbound lanes were open. Visit the Gateway Guide web site for more traffic information (http://www.gatewayguide.com). John Whitaker, an on-scene coordinator for the Missouri Department of Natural Resources, said about 4,600 gallons of ethanol from the 6,400-gallon tank spilled. He said some of the fuel ran into Watkins Creek, which empties into the Mississippi River about a half-mile away. Whitaker said he saw some dead minnows in the creek. Personnel from the Missouri Conservation Department were en route to look at the extent of the wildlife damage. Ethanol mixes with water, so it was impossible to remove it from the creek. "It's not highly toxic to the environment," he said. "It will break down fairly quickly." Some households were evacuated while emergency crews tried to contain the highly flammable liquid. Whitaker said he tested air samples with an instrument that measures flammable vapors. "We didn't get any readings at all, so we feel it's pretty safe," he said. "I dont think there will be too much of a lasting impact," Whitaker said. "Initially there was a pretty high impact, but it's not going to be persistent." Sean A.
