SIDNEY, Ill. (AP) — The Illinois Environmental Protection Agency says Union Pacific Railroad has failed to properly clean up diesel fuel that leaked from one of its trains into the Salt Fork River in eastern Illinois. The agency asked the state’s attorney general Friday to compel the railroad to do more to mitigate the May 2 spill near the village of Sidney in Champaign County. Railroad spokesman Mark Davis says the company’s cleanup contractor has been at work since the incident and its environmental team would continue to cooperate with federal and state agencies. The diesel leaked from fuel tanks on three locomotives. Village President Chuck White tells The (Champaign) News-Gazette that at least 2,000 gallons was released. The state EPA says the Union Pacific contractor failed to contain all of the fuel.
