SITE BACKGROUND <br /> <br />The subject property was previously owned by Libby Owens Ford/Pilkington North <br />America (LOF/PNA) that operated a plant to the north of the Site at 500 East Louise <br />Avenue. The LOF/PNA facility utilized the property immediately east of the Site, at <br />17100 Murphy Parkway, and the subject property, to manage/handle and dispose of solid <br />waste generated at the LOF/PNA plant. The solid wastes comprised largely of waste <br />glass materials including glass cullet and glass processing waste. The glass processing <br />waste included the raw materials utilized to process glass including waste glass, mixed <br />industrial debris (including plastics or laminates, small metal objects/debris, and <br />baghouse dust), and potentially burnt debris. In the 1980s, the parcel was divided creating <br />the 10.01-acre subject property parcel and the cogeneration facility was constructed in <br />1989. <br /> <br />The former LOF/PNA facility to the north contained unpermitted landfill cells that resulted <br />in discharge of wastes, including dioxin/furan compounds (dioxins), PCBs, and total <br />petroleum hydrocarbons (TPH) to soil. The only PCB congener detected was PCB Aroclor <br />1254. These chemicals are considered the constituents of concern (COC) at the Site. <br />Two primary waste cells reported as the North Waste Cell and South Waste Cell were <br />assessed and remediated up to what was thought to be the boundary of the cogeneration <br />parcel. Investigations performed at the subject property in 2019 and 2020 determined that <br />both waste cells continued onto the subject property (Waste Cell No. 1 and 1A), to the <br />south of the former power plant. Additionally, the investigations identified two distinct <br />waste cells (Waste Cell No. 2 and 2A), and isolated areas of waste, beneath the central <br />and southern areas of the former power plant. The waste cells are composed of glass <br />processing waste, and not glass cullet, disposed on the subject property by the former <br />LOF/PNA facility. <br /> <br /> <br />2.3. SITE USE <br /> <br />The subject property has been unoccupied and vacant since the power plant was <br />demolished in 2017. There are currently no buildings at the Site. Concrete foundations <br />and structures from the former Site buildings, equipment, and machinery are still present <br />in the power plant area, as well as underground infrastructure. The future plans for the <br />subject property involve redevelopment for industrial use. However, no specific plans <br />have been developed as of the date of this report. <br /> <br /> <br />2.4. CURRENT SITE ENVIRONMENTAL CONDITIONS <br /> <br />There are two Areas of Concern (AOCs) at the Site: 1) the area along the eastern property <br />boundary, south of the former power plant (East Property Boundary or AOC1); and 2) the <br />location of the former cogeneration facility (Former Power Plant or AOC2). Glass <br />processing waste was encountered beneath both AOCs. <br />
