On-Site Infrared Incineration
- Excavated material screened and blended with fuel oil prior to incineration
- PCBs and VOCs volatilized and partially destroyed in primary combustion chamber
- Kiln ash quenched by water-cooled screw
- Exhaust gas from kiln directed to air pollution control system, consisting of secondary combustion chamber (SCC)
- Wastewater treated on-site and discharged under NPDES permit

PCBs, metals, and volatile and semivolatile organic compounds
- Most common contaminants (and maximum concentrations) were toluene (4,700 mg/kg), ethylbenzene (430 mg/kg), chlorobenzene (570 mg/kg), xylene (1,400 mg/kg), naphthalene (31 mg/kg), pentachlorophenol (32 mg/kg), acetone (76 mg/kg), and total phthalates (91 mg/kg)
Waste disposal areas in landfills and surface impoundments wastes included spent solvents, paint sludges, lead battery sludges, waste oils
Type/Quantity of Media Treated:
- 34,000 tons of surface and subsurface soil
Purpose/Significance of Application:
Operating in winter led to weather-related difficulties resulting in suspension of the operation until spring.
Regulatory Requirements/Cleanup Goals:
Destruction and Removal Efficiency (DRE) of 99.9999% for principal organic hazardous materials as required by Resource Conservation and Recovery Act (RCRA) regulations in 40 CFR part 264, subpart O; DRE of 99.9999% for PCBs as required by Toxic Substances Control Act (TSCA) regulations in 40 CFR part 761
EPA determined that demonstration of a 99.9999% DRE for PCBs was not necessary during the trial burn because (1) substantial hazards were associated with transporting and storing concentrated PCB oils, and (2) the unit had demonstrated the ability to adequately destroy PCBs in order to obtain its TSCA permit
From 1966 to 1968 approximately 5,000 drums containing spent solvents, paint sludges, lead battery sludges, and waste oils were buried in a 12-acre area at the Rose Township Dump site. Bulk wastes were also discharged to the surface or into shallow lagoons or pits in the area. On September 30, 1987, EPA signed a Record of Decision (ROD) specifying on-site incineration as the selected remedy for contaminated soil at the site. A consent decree was signed by 12 potentially responsible parties (PRPs) and EPA in 1988 to remediate the site.
The incinerator used to process soils at the site was the OHM Mobile Infrared Thermal Destruction Unit (TDU). The PCBs and VOCs were volatilized and partially destroyed in the primary combustion chamber. Off-gases from the preliminary combustion chamber were routed to a secondary combustion chamber (SCC) for further destruction of any remaining VOCs and PCBs. Kiln ash was quenched by a water-cooled screw. During the on-site incineration remedial action, 34,000 tons of contaminated soil were incinerated. Treatment performance and emissions data collected during this application indicated that all performance standards and emissions requirements were achieved.
The total cost for remediation using the incineration system was approximately $12 million.
