Cleanup
Type:

Remedial action

Vendor:

ENSCO, Inc.

Technology:
On-site Incineration
- Incineration using direct-fired rotary kiln
- Screening and mixing of contaminated sediments prior to incineration
- Quenching of kiln ash in water bath
- Treatment of wastewater from system on-site and discharge to nearby creek
- Combustion of remaining VOCs and PCBs in secondary combustion chamber (SCC)

Contaminants:
Polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), and metals
- benzene
- cadmium
- methylene chloride

Waste Source:
Lagoon Sediments--waste oil storage and reprocessing operations waste

Type/Quantity of Media Treated:
Lagoon sediments and sludges, debris, levee material, lagoon oil, and soil (172,000 tons)

Purpose/Significance of Application:
Inadequate design caused numerous mechanical problems; incineration operation suspended twice because of mechanical problems; problems with demulsifying complicated dewatering of sediment

Regulatory Requirements/Cleanup Goals:
Destruction and Removal Efficiency (DRE) of 99.99% for VOCs as required by Resource Conservation and Recovery Act (RCRA) incinerator regulations in 40 CFR Part 264, Subpart O; The DRE of 99.9999% for PCBs and ash residual as required by Toxic Substances Control Act (TSCA) regulations in 40 CFR Part 761

Results:
Emissions and trial burn data indicate that all DRE and emission standards have been met

Description:
Between the 1960s and continuing through 1981, an on-site lagoon was used for disposal of wastes from waste oil reprocessing operations conducted on site. Lagoon sediment was contaminated with PCBs at concentrations greater than 500 mg/kg, as well as VOCs and metals.

In 1984, EPA signed a Record of Decision (ROD) specifying on-site incineration as the selected remedy for the sludge, sediment, soil, debris, and lagoon oil at the site. Remedial actions were managed by the U.S. Army Corps of Engineers (COE) under the oversight of EPA Region II.

The material to be incinerated was excavated from the lagoon, and screened and mixed before incineration. The material was then conveyed into a rotary kiln by a screw auger. The incineration system also included a secondary combustion chamber (SCC) to provide further destruction of any VOCs and PCBs. Kiln ash was quenched in a water bath. Wastewater from the incinerator was treated in an on-site wastewater treatment system and discharged to a nearby creek. Exhaust gas from the kiln was directed to an air pollution control system (APCS). The APCS consisted of a cyclone separator for removal of larger particulates; a secondary combustion chamber (SCC) for destruction of any remaining VOCs and PCBs.

During its 50 months of operation, the incinerator processed over 172,000 tons of sediment, sludge, debris, oil, and soils. Treatment performance and emissions data collected during this remedial action indicated that all performance standards and emissions requirements were achieved.

The actual cost for remediation using the incineration system was approximately $187,000,000 (includes costs associated with treatment of lagoon water and removal of tank farm).
