Hazardous Waste Generation and Handling Fee
Application of Fee
As of January 1, 2022, the hazardous waste generator fee has been repealed and replaced with a new generation and handling fee (Senate Bill 158; Stats. 2021, ch.73).
Prior to January 1, 2022, the hazardous waste generator fee was imposed on a tiered category basis.
Effective January 1, 2022, the hazardous waste generation and handling fee is imposed as 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. Hazardous waste generally includes recycled waste, non-manifested treated wood waste, non-manifested universal waste, imported waste, and waste sent outside California for disposal.
A generator is any person, by site, whose act or process produces hazardous waste or causes hazardous waste to become subject to regulatory control by a government agency authorized to regulate hazardous waste.
The hazardous waste generation and handling fee is calculated based on the total weight (measured in tons) of hazardous waste generated (produced or caused to be managed) from each site per year. The hazardous waste generation and handling fee is generally due regardless of the waste's final disposition. You should keep weight tickets to support the actual weight or quantity you are reporting. For more information, please visit the Department of Toxic Substances Control's (DTSC) Manifest webpage or Fee Summary webpage.
The total tonnage you report on the hazardous waste generation and handling fee return should include non-manifested hazardous waste, such as treated wood waste. Please visit DTSC's website for more information on Requirements for Generators of Treated Wood Waste (TWW).
Please note: Facility operators who pay the facility fee are now subject to the generation and handling fee (HSC section 25205.5).

Prepayments, Returns, and Payments
Generation and handling fee account holders are required to file a return each year and pay the fee in two equal payments for each fiscal year. Below is information regarding prepayments, filing returns, and making payments for the generation and handling fee.
Prepayments
Generation and handling fee account holders are required to make one prepayment, which is due and payable on or before the last day of November of each fiscal year and file a return and final payment due on or before the last day of February of the same fiscal year.
- Prepayment – Due the last day of November of each fiscal year. The prepayment must be equal to 50 percent of the total amount of the fee due.
- Final Payment with Return – Due on the last day of February of the same fiscal year. The final payment is the remaining 50 percent of the fee due.
The total amount of the fee due is based on hazardous waste generated in the prior calendar year.
For example:

The escalating penalties are capped at 100 percent and in addition to any other penalties imposed under the Hazardous Substances Tax Law. These penalties are calculated based on the following schedule.
Penalty | Number of days received after the due date | |||
---|---|---|---|---|
30 days or fewer | 31-60 days | 61-90 days | 91 days or more | |
Late prepayment | 10% | 25% | 50% | 100% |
Late filing | 10% | 25% | 50% | 100% |
Late payment | 10% | 25% | 50% | 100% |
For payments and returns due on and after November 30, 2024, we will also apply a new 300 percent penalty if we determine that you willfully or knowingly provide incorrect information or withhold information that results in a deficient payment of the generation and handling fee. This is in addition to any other penalties imposed under the Hazardous Substances Tax Law.
