Emergency crews were busy Sunday cleaning up a fuel spill in Ellicott Creek near Millersport Highway in Amherst after someone poured the fuel into two concrete pipes.
Amherst fire officials said a passer-by was on the bike path when he called police on his cell phone about 10:25 a.m. to report the incident.
"He smelled diesel and walked over and saw a sheen -- a shiny substance on top of the water -- and he could tell something had spilled," said Amherst fire dispatcher Tom Merrill.
The Getzville Fire Company, the state Department of Environmental Conservation, Amherst police and the Town of Amherst's emergency coordinator responded to the scene.
The substance was either fuel oil or diesel fuel, according to officials, who said they determined that the spill was not toxic to humans.
Fire crews used booms to contain and absorb the substance. The cleanup was scheduled to resume today. Fire officials said they are also trying to determine where the substance originated and who placed it in the water.
