Technology:
On-site incineration
- Soil was pretreated with crushing and shredding to achieve a homogenized incinerator feed
- Incineration system consisting of rotary kiln and secondary combustion chamber (SCC)
- SCC temperatures averaged 2000°F
- Ash was discharged, and returned to the excavated areas on site

Waste Source:
Disposal of manufacturing wastes in an open trench |
Type/Quantity of Media Treated:
Liquids
- Soil (51,000 tons) |
Purpose/Significance of Application:
Incineration of PCB-contaminated soil |
Regulatory Requirements/Cleanup Goals:
Destruction and Removal Efficiency (DRE) of 99.9999% for PCBs as required by Toxic Substances Control Act regulations in 40 CFR part 761 subpart D |
Results:
Treatment performance and air monitoring data collected during this application indicated that all required performance and standards emissions were achieved. |
Description:
Between 1951 and 1959, the 14-acre residential lot received wastes from a nearby manufacturer. Soil at the site was contaminated with PCBs as well as volatile organic compounds (VOCs). A Record of Decision signed September 23, 1988 and November 21, 1989 specified on-site incineration as the remedial technology for the soil and sediments. Site cleanup goals and DRE standards were specified for constituents of concern.
On-site incineration began in February 1994 and was completed in July 1994. The treatment system consisted of a rotary kiln and an SCC. Kiln ash was treated and stored and treated gas was exhausted to a stack. Incineration has achieved the soil cleanup goals specified in the ROD.
No information was available on costs for the remedial action. |
