A list of thermal treatment facilities approved by the DEQ to receive PCS is available for your reference. While treatment processes that result in the destruction of the hydrocarbons are preferred, soil aeration may be a somewhat less expensive means for dealing with soil contamination. Aeration works best for gasoline contaminated soils and has limited success with diesel or heavier hydrocarbons. This method involves the volatilization of hydrocarbons into the atmosphere. Also, gasoline contains benzene, which is a carcinogen.
Soil aeration involves more than just spreading or piling the soil and letting it sit.
The process requires the use of specific controls to prevent the creation of other problems and considerable work is needed to ensure that treatment is effective in reducing contaminant concentrations to an acceptable level. There are some restrictions on how the treated soil can be reused. Contact the regional DEQ office that has jurisdiction for your cleanup project for more information. The Department may waive the permit fee if you are otherwise reimbursing the Department for oversight costs. You will need to obtain approval for the treatment site from the local land use authorities before you proceed.
