摘要

Excavation and thermal treatment of MGP impacted soils is the technology most often selected when cleaning-up coal tar contaminated sites. Often, the excavated material is transported to an off-site fixed facility for treatment. Because all of the existing fixed thermal facilities (other than hazardous waste permitted incinerators) can only treat non hazardous soils, material was rendered on site to create the non-hazardous stream shipped for treatment. Since the Bevel Amendment which allowed on-site rendering of hazardous soils to a non-hazardous state recently expired, management and disposal of hazardous MGP residuals has become more challenging. A new hazardous waste recycling option for treating hazardous MGP residuals which carry D018 or other petroleum distillate waste codes has recently become available. This option is a fixed thermal facility which can accept manifested hazardous wastes including coal tar solids and sludges, treat it through their three-phase thermal process and create a clean treated soil or sludge stream while collecting the recyclable petroleum distillates which have been extracted from the soils or sludges for further use. The process, known as indirectly heated thermal desorption, is considered by the U.S. EPA as well as numerous RCRA authorized states as a legitimate recycling and reclamation process (as opposed to hazardous waste treatment). Fully permitted and operational, it is being used to recycle the Utility Industry's RCRA hazardous wastes, such as coal tars, as well as by major Petroleum Refinery and Chemical Industry clientele. This paper will present in detail the operational and regulatory basis for this facility and describe a recent soil remediation project in which coal tar distillates were successfully recycled through this process.
