This subsection applies only to that portion of the public used oil collection center used for the collection of used oil and does not apply if the owner or operator is grossly negligent in the operation of the public used oil collection center. Nothing in this section shall affect or modify in any way the obligations or liability of any person under any other provisions of state or federal law, including common law, for injury or damage resulting from a release of used oil or hazardous substances. For the purpose of this section, the owner or operator of a used oil collection center may presume that a quantity of no more than 5 gallons of used oil accepted from any member of the public is not mixed with a hazardous substance, provided that such owner or operator acts in good faith.
