58 Pa. Stat. § 471
The Legislature finds that a substantial number of gallons of used oil are generated each year in this Commonwealth; that used oil is a valuable petroleum resource which can be recycled and reused and that in spite of the potential for recycling, significant quantities of used oil are wastefully disposed of or improperly used by means which pollute the water, land and air, and endanger the public health and welfare. Used oil should be collected, recycled and reused to the maximum extent possible, by means which are economically feasible and environmentally sound, in order to conserve irreplaceable petroleum resources, preserve and enhance the quality of natural and human environments, reduce our dependence on imported foreign oil and protect the public health and welfare.
