The 9-acre Laskin/Poplar Oil Company site is located in Ashtabula County, Ohio. A waste oil storage area and a greenhouse were formerly located on site. The owners used waste oil to heat the greenhouse and for road oiling. Some of the waste oil was contaminated with polychlorinated biphenyls (PCBs) and other hazardous constituents. Later, the owner began collecting, reselling and disposing of waste oils. A court order shut down the operation in 1981. Hazardous liquids stored in tanks and ponds had the potential to overflow or otherwise release contaminants into nearby Cemetery Creek, affecting a downstream drinking water supply. Following cleanup, EPA took the site off the Superfund program�s National Priorities List (NPL) in 2000. Operation and maintenance activities are ongoing.
