MOUNT CARMEL, Ill., Rajab 12, 1437, April 19, 2016, SPA -- A pipeline spill that dumped 48,000 gallons of diesel into a river that forms the border of southern Illinois and Indiana has had no effect on wildlife, a U.S. Environmental Protection Agency official said Tuesday, according to AP. The Wabash River is at about flood stage and the enormous volume of water is helping dilute the fuel, which is expected to be undetectable by the time it reaches the Mississippi River later Tuesday, EPA on-scene coordinator Kevin Turner said. Marathon Pipe Line LLC is investigating whether the fuel is from its network and has shut down its Two Rivers pipeline system, which crosses under the Wabash River at Mount Carmel, Illinois. The pipeline delivers fuel from a refinery in Robinson, Illinois, to a terminal in Mount Vernon, Indiana, on the Ohio River. The fuel sheen was first spotted Sunday near Mount Carmel and quickly spread to the Ohio River. There was no word on what caused the leak. Authorities are monitoring the fuel plume's movement and notifying water intake facilities along the rivers to protect drinking water supplies as needed, Turner said. Findlay, Ohio-based Marathon Pipe Line said there has been no impact to drinking water. --SPA 22:37 LOCAL TIME 19:37 GMT www.spa.gov.sa/w
