According to EPA, when you have a chemical spill, you must take “immediate response” and clean up the spills. The agency does not define what it means by “immediate”. It is more of a matter of judgment made on a individual basis. In general, EPA expects a facility to begin cleaning up within 24 hours and no later than 72 hours after the spill. Failure to clean up a spill could lead to enforcement action for illegal disposal of hazardous waste.
If you spill gasoline on the ground, the soil that has been soaked with gasoline will most likely fail the TCLP (Toxic Characteristic Leaching Procedures) test due to the presence of benzene – a TCLP contaminant. That means the soil is now a characteristic hazardous waste and must be disposed of as much.
This is one of the many topics discussed at our 2-day seminars.
