Cal. Pub. Res. Code § 3462

The Legislature finds that almost 100 million gallons of used automotive and industrial oil are generated each year in the state; that used oil is a valuable petroleum resource which can be recycled; and that, in spite of this 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.
