The subject tanks were associated with the former Tonawanda Coke Corporation’s past coking operations. The site of these three tanks was primarily used for main plants shipping and deliveries by way of the Niagara River which included coke, coal, and coal tar. It is understood that the three tanks were used for storage of coal tar produced from the coking operations. Under an order by the US EPA, OSC was contracted to remove the three tanks and the contents.
Health & Environmental Risks
Hazardous levels of coal tar
Structural considerations included poor condition of the tanks which were beyond repair and in danger of failing at any point in time due to previous operations that were ceased.
Sensitive odor-control issues due to the nature of contamination and proximity to the Niagara River and surrounding businesses.
Mechanical and manual demolition of three 750,000 gallon above-ground storage tanks
Remediation included excavation, stabilization and off-site disposal of over 5,000 tons of hazardous coal tar impacted soils, concrete and steel debris.
Removal of 1,200 tons of non-hazardous impacted soils
Design & fabrication of a water treatment system to treat over 1,000,000 gallons of impacted water from the surrounding berms and from within the three tanks.
Demolition of over 800 CY of concrete tank slabs and foundations.
Restoration of tank farm areas included importing clean fill and establishing new turf.
