Fact Sheet 3

Veolia ES Orchard Hills Landfill and Winnebago Landfill Odor Updates

Fact Sheet #3

February 2011

Ogle and Winnebago Counties, Illinois


The purpose of this fact sheet is to provide information to and educate citizens about landfill odors and the corrective measures that Veolia ES Orchard Hills Landfill and the Winnebago Landfill have been undertaking to alleviate the odors. In order to keep area residents informed, fact sheet updates will be distributed as landfill activities progress at each facility.

Over the past several months, odors have been an issue for persons living within the vicinity of the Orchard Hills Landfill owned by Veolia ES and the Winnebago Landfill owned by the William Charles Company. Because of these odors, the Illinois Environmental Protection Agency (Illinois EPA) has been working with both landfill companies to determine the source of the odors and more importantly, how these odors might be eliminated. On October 13, 2010, the Illinois EPA sent both landfills a NIPLA (Notice of Intent to Pursue Legal Action) citing violations of the environmental statutes. This action by the Illinois EPA has resulted in the landfill companies responding with a variety of proposed remedies.
