California Code, Health and Safety Code - HSC § 25250

(a) The Legislature finds that almost 100 million gallons of used oil is generated each year in the state; that this 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, safety, and welfare.

(b) The Legislature also finds that readily available technologies exist to recycle used oil into useful products and that used oil should be collected and recycled, to the maximum extent possible, by means which are economically feasible and environmentally sound, in order to conserve irreplaceable petroleum resources, to protect the environment, and to protect public health, safety, and welfare.
