We make sure there isn't any chemicals in the drums, rinse them out well, remove the labels and sell the 30 and 55 gallon drums. The smaller containers we remove the label, rinse them give them away. You want to be very sure you remove your name off the containers. A car wash friend of mine, used to set his drums out by the street. He got a letter then a call from the EPA asking how he intended to pay from the removal of his half full drum of comtaminated diesel fuel from a small island up in Alaska. It was thousands of dollars.
