California Public Resources Code Section 48652

The board shall set the recycling incentive amount at not less than four cents ($0.04) per quart. The amount may be set at an amount higher than four cents ($0.04) if the board determines that a higher amount is necessary to promote recycling of used lubricating oil and sufficient funds are available in the fund. The board shall not change the amount of the recycling incentive until at least one year has passed since the amount was last set. The board shall continue providing recycling incentives to certified used oil collection centers at the previous rate for one month after setting the recycling incentive at a different rate. The board shall not raise the recycling incentive amount unless it finds that the raise will not adversely affect funding required pursuant to Sections 48631, 48653, and 48660.5.
