When the cleanup process began, there were also large areas of general construction debris and spent oxide box filler - wood chips that had been coated with iron oxide dust and exposed to raw manufactured gas to remove impurities from the gas.
The first large-scale phase of the remediation process began in 1991, with the excavation of the spent oxide box filler waste.
Starting in July 1991, approximately 14,000 cubic yards of spent oxide box filler was excavated, screened, and stockpiled on site.
confining the process of crushing and screening spent oxide box filler to the interior of a specially constructed building with an air filtration system, so that dust and odor-causing agents could be collected and removed;
covering the stockpiles of screened spent oxide box filler with high-density polyethylene tarpaulins to prevent volatilization and to minimize the release of dust; and
transporting the spent oxide box filler in covered trucks.
After the spent oxide box filler was excavated, an estimated 40,000 cubic yards of contaminated material, including coal tars and contaminated soils, still remained at the site.
When excavation of the spent oxide box filler began in 1991, there was an outcry from local residents about odors from the site.
The "principle contaminants" on the site were wastes from tar production including coal tar and a variety of derivatives, materials from gas purification including foul lime, clinker waste and spent oxide and carboniferous materials including coal and coke.
The major solid wastes at cokemaking plants are tar residues, sludges, spent oxide box wastes, residues from materials handling, by-product recovery, wastewater disposal sludges and ashes.
