Background: California auto dealers are charging for expenses related to management and disposal of hazardous wastes generated during servicing an automobile since 1989. The dealers are allowed to recover the expenses, both direct and indirect, incurred in managing and disposal of wastes generated during servicing automobiles. The used oil haulers who were once paying dealers for oil in the amount of $0.85 to $1.00 per gallon are no longer paying. This is the direct consequence of the reduction of the price of crude oil.
