The CROSS-FIRE footprint:
The portable remediation trailer takes up less than 380 square feet on site. That is a little less than the length of one and one half dump trucks.
This is one of the cleaner methods of soil remediation: This high temperature form of thermal desorption that economically utilizes propane as its fuel source is considered by many states as being an insignificant source of air emissions. A technical analysis report concluded “cumulative emissions from operating the unit are insignificant.”
Not only are the emissions insignificant: “The temperature of the hot burner flame in contact with the soil serves as an emission control device that is equivalent to an afterburner in traditional SRUs (soil remediation units) that operate at much lower temperatures”(source : Technical Analysis Report by AK DEP).
This technology was used to clean contaminated soil at a convenience store during an underground tank removal. This highly contaminated location was cleaned up beyond the levels required by the state environmental agency. The cleaned soil was sampled and returned to the excavation. This process saved more than $60,000 at this location.
Utilizing CROSS-FIRE put less air emissions into the atmosphere than the small fleet of dump trucks formerly required just to relocate the problem to a treatment, storage or disposal location.
