A hazardous materials response was called Thursday night after a strong odor of gas was detected and a sheen of oil was visible in water along the Indian Trail in Kankakee.
The Limestone Fire Department was called just before 11 p.m. to check out the odor at Indian Trail and Route 13. Responders found a petroleum pipeline, owned by Buckeye Terminal, and a sheen in the water of a culvert.
That culvert runs toward the Kankakee River.
Fire officials called MABAS -- the Mutual Aid Box Alarm System -- for assistance. Officials from Buckeye Terminal, as well as the Illinois Environmental Protection Agency and the Coast Guard, were also called.
The origin of the leak was discovered and crews were still on the scene as of 5:30 a.m. It wasn't immediately known how much of the material was released.
There were no evacuations ordered and no injuries reported.
