Abstract:  The Allied Chemical & Ironton Coke site is located in Ironton, Ohio and covers approximately 95 acres. The site operated from 1920 until 1982 and consists of a dismantled Coke Plant and five lagoons which received process wastewater and hazardous solid waste from the former Coke Plant. A 4-acre waste pit called the Goldcamp Disposal Area is also part of the site and an operating AlliedSignal Tar Plant is located within the site boundaries. The Allied Chemical/Ironton Coke site is divided into two operable units, the Goldcamp Disposal Area (GDA) and the Coke Plant/Lagoon Area (CPLA). This is the second amendment issued since the original ROD. This amendment reflects changes to the ROD soils remedy at the CPLA.
 
Remedy:  The original remedy selected for the site consists of incineration of approximately 122,000 cubic yards of lagoon waste materials and on-site re-use of the waste heat generated during incineration; in-situ bioremediation of approximately 457,000 cubic yards of contaminated soil materials; off-site disposal of approximately 40,000 cubic yards of contaminated soil material, called the "ROD soils"; pumping and on-site treatment of groundwater; downgradient groundwater monitoring of Ice Creek and preparation of a contingency plan; and implementation of deed restrictions, fencing, and security.The remedy selected for the 40,000 cubic yards of "ROD soils" has been amended. The cleanup replaces prepared pad bioremediation with off-site disposal in an approved landfill.
