ABSTRACT
Used oil is a valuable resource, but it can be an environmental problem and financial liability if improperly disposed of. Used oils pose hazards to human health and the environment, and therefore need to be managed safely. The mismanagement of used oil can contaminate air, water, and soil. Contamination primarily occurs from improper storage in containers and tanks, disposal in unlined impoundments or landfills, burning of used oil mixed with hazardous waste, improper storage practices of used oil handling sites and associated facilities, and road oiling for dust suppression.
