The state of California has levied a fee for many years on hazardous wastes generated by auto dealers and others.  The fee structure specifically exempted used oil generated at auto dealerships.  California SB 158, effective January 1, 2022, specifically removes the exemption on used oil from the fee and adds other wastes that are now subject to the fee.  The hazardous waste Generation and Handling (GH) fee is a flat rate per ton or fraction of a ton on generators of hazardous waste for each generator site that generates five or more tons of hazardous waste at a site in California within a calendar year.

Wastes subject to this fee include recycled hazardous waste, non-manifested treated wood waste, non-manifested universal waste, imported waste, and waste sent outside California for disposal. Used motor oil now gets added to the category, where previously only waste coolant (CA code 134), oily water (CA Code 223), and waste paper filters (CA code 352 or 223) were present.  In the past, the first 5 tons were exempt from taxes, most claimed exemption.  Not anymore.  Also, if you are punching or crushing metal oil filters, under DTSC guidelines, you can dispose of it as scrap metal and hence not be subject to this fee.  If you decide to dispose of used metal oil filters as hazardous waste, those metal filters get added to your hazardous waste tax calculations. 


The hazardous waste generation and handling fee is generally due regardless of the waste’s final disposition. Weight tickets should be maintained to support the actual weight/quantity being reported. Please reference DTSC fee chart below:
