(a) The Legislature hereby finds and declares that changes made to the imposition and administration of the disposal fee, generator fee, and transportable treatment unit fee set forth in Sections 28, 54, and 64 of Chapter 73 of the Statutes of 2021 were not intended to repeal the authority of the Department of Toxic Substances Control and the California Department of Tax and Fee Administration to continue to administer and collect those fees.
