| Abstract: | Ogden Environmental Services Inc. (OES) is operating a PCB incineration project on the Kenai Peninsula, Alaska. The facility is approximately 150 miles from Anchorage, Alaska, on a U.S. Fish and Wildlife Service refuge and recreation area. Before attaining its current status, the area was an oil field; pipelines and compressor stations are still in the area. Ogden's facilities are located adjacent to an operating compressor station in an area transected by pipelines. The site became contaminated with PCBs as an indirect result of a compressor explosion in 1972. In March 1988 OES contracted to remediate the site using its proprietary transportable Circulating Bed Combustor (CBC), an advanced technology fluidized bed incinerator. The project will thermally treat more than 80,000 tons of PCB-contaminated soil. Treated soil (ash) contains less than 0.1 ppm PCB and is permanently placed on site. Ogden designed, constructed, permitted, conducted trial burns, and made fully operational this major facility on the remote Kenai Peninsula of Alaska. All systems were designed to withstand the rigors of shipping and to be highly reliable in cold weather and remote-site operations. |
