The California Department of Tax and Fee Administration (CDTFA) administers four hazardous waste fee programs in cooperation with the Department of Toxic Substances Control (DTSC), pursuant to the requirements of the California Hazardous Substances Tax Law.

We created this guide to provide easily accessible information to assist you in understanding your obligations related to the hazardous substances programs.

For hazardous substances programs previously administered by CDTFA such as the activity fee, please visit our Industry Topics page.

Hazardous Substance Programs

Disposal Fee

Persons who dispose of hazardous waste to land at an authorized hazardous waste disposal facility in California will pay a disposal fee directly to the disposal facility, and the disposal facility then submits the fee and a return to CDTFA. The hazardous waste generation and handling fees may also apply; refer to the Generation and Handling Fee section for more information.

The fee varies and is determined by the waste category and the total tonnage of waste. Only the disposal facilities/operators are required to file returns with the CDTFA. (Health and Safety Code (HSC) section 25174.1, et seq.)

The hazardous waste disposal fee ends on June 30, 2022 (Senate Bill 158; Stats. 2021, ch.73).

Environmental Fee

The environmental fee is imposed on businesses/organizations in industry groups that use, generate, store, or conduct activities related to hazardous materials. Activities related to hazardous materials may include the use of products such as ink, plastics, paint, etc., which were manufactured using hazardous materials. The fee applies to corporations, general partnerships, limited partnerships, limited liability partnerships, limited liability companies, and sole proprietorships that have the qualified number of employees who are each employed more than 500 hours in California during the calendar year. The qualifying number of employees for the years prior to 2022 is 50 or more. Effective January 1, 2022, the qualifying number of employees is 100 or more. The fee is graduated based on the number of employees. (HSC section 25205.6.)

Facility Fee

The facility fee applies to an owner or operator of a site that is permitted by DTSC to treat, store, or dispose of hazardous waste in California. Facility fees are based on statutory provisions set forth in the Health and Safety Code, utilizing a tiered permitting program. Facility fees are classified into five tiers: Full Facility Permit, Standardized Permit, Permit-by-Rule, Conditional Authorization, and Conditional Exemption. The fees vary according to the permitted level. (HSC sections 25205.2 – 25205.4, and 25205.7.)

Generation and Handling Fee

The generator fee is repealed and replaced by a new generation and handling fee effective January 1, 2022 (Senate Bill 158; Stats. 2021, ch.73). The generation and handling fee applies to each generator of hazardous waste at each generation site that generates five or more tons of hazardous waste per calendar year or portion of the calendar year. This includes most recycled waste, treated wood waste, imported non-RCRA (Resource Conservation Recovery Act) waste, and waste sent outside California for disposal. The per ton fee is determined by the total tonnage of waste generated per site. The fee also applies to facility operators that generate five or more tons of hazardous waste who pay the facility fee. (HSC section 25205.5.)

Generator Fee

Prior to January 1, 2022, the hazardous waste generator fee was imposed on anyone who generated five or more tons of hazardous waste on a tiered category basis.

How the Revenue is Used

The revenue we collect for DTSC is used to support hazardous waste management in California including the review and analysis of past, present, or potential environmental public health effects related to toxic substances.

Application of Fee

The hazardous waste disposal fee is imposed on persons who dispose of hazardous waste to land at an authorized hazardous waste disposal facility in California. The hazardous waste disposal fee is charged based on the total weight (measured in tons) and the type of hazardous waste. The disposal fee is paid directly to the disposal facility, and the disposal facility submits the fee and a return to CDTFA.

The hazardous waste disposal fee ends on June 30, 2022 (Senate Bill 158; Stats. 2021, ch.73).

Registration

There is no online registration for this program with CDTFA.

Each disposal facility must obtain a hazardous waste ID number, a hazardous waste facility permit (HSC section 25205.2) or a grant of authorization from the Department of Toxic Substances Control (DTSC). DTSC provides CDTFA a list of permitted hazardous waste disposal facilities. We register each disposal facility based on DTSC's list.

The facility must then collect the hazardous waste disposal fees from their customers and remit the hazardous waste disposal fee to us.

Fee Rates

Hazardous waste disposal fee rates are set by statute (HSC section 25174.6). The rates are adjusted annually to reflect increases or decreases in the cost of living as measured by the Consumer Price Index (CPI) issued by the Department of Industrial Relations.

Visit the Tax Rates - Special Taxes and Fees page to view current and historical hazardous waste disposal fee rates.

Hazardous waste disposal fee rates are also listed on DTSC's Fee Summary webpage.

Return and Payment

The hazardous waste disposal fee return and payment are due monthly on the last day of the third calendar month following the period for which the hazardous waste disposal fee is due. For example, the January 2021 return is due on or before April 30, 2021.

  • Beginning January 1, 2022, the qualifying number of employees is 100 or more employees that have worked more than 500 hours during the calendar year.

The number of qualifying employees is determined by counting the number of employees who are employed in California more than 500 hours. This includes vacation, sick leave, and holidays for which an employee is paid during their employment. If a person terminates employment, vacation, sick leave, holidays or other severance pay is not included when calculating the number of hours.

The fee does not apply to a nonprofit corporation primarily engaged in the provision of residential social and personal care for children, the aged, and special categories of persons with some limits on their ability for self-care, as described in SIC Code 8361 of the Standard Industrial Classification (SIC) Manual published by the United States Office of Management and Budget, 1987 edition or as described in Codes 623220, 623312, and 623990 of the North American Industry Classification System (NAICS) published by the United States Office of Management and Budget, 2017 edition.

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. This 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. Weight tickets should be maintained to support the actual weight/quantity being reported. For more information, please visit the Department of Toxic Substances Control's (DTSC) Manifest webpage or Fee Summary webpage.

The total tonnage reported on the hazardous waste generation and handling fee return should include non-manifested 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.)

Definitions

Below are definitions for the hazardous waste programs.

RCRA and non-RCRA Hazardous Waste

The Resource Conservation Recovery Act (RCRA) is a federal statute which regulates facilities that treat, store, and/or dispose of hazardous waste. All RCRA hazardous wastes are identified in Part 261 of Title 40 of the Code of Federal Regulations and Appendices.

Non-RCRA Hazardous Wastes are considered those wastes which are regulated in California, other than the federally regulated RCRA hazardous wastes.

Uniform Hazardous Waste Manifest

A Uniform Hazardous Waste Manifest is the shipping document or bill of lading that travels with the hazardous waste from point of generation, through transportation, to the final treatment, storage, or disposal facility. It contains information about the type and quantity of hazardous waste and identifies the generator and location from where it was removed, the hazardous waste transporter, and the treatment, storage, and/or disposal facility. For more information on hazardous waste manifests, visit the Department of Toxic Substances Control website.

Required Registration with other Agencies

The following hazardous waste programs are required to register with other agencies:

  • Disposal Fee
  • Generation and Handling Fee
  • Facility Fee

Treatment, storage, and disposal facilities must obtain either a state or federal hazardous waste ID number as well as a hazardous waste facility permit (HSC section 25205.2) or a grant of authorization from the Department of Toxic Substances Control (DTSC).

Additionally, anyone who generates, transports, offers for transport, treats, stores, or disposes of hazardous waste generally must have a hazardous waste ID number. A hazardous waste ID number is used to identify the hazardous waste generator, transporter, and facility that handles hazardous waste.

Visit the sites below for more information about other state, federal, and local taxing and licensing information:

  • The Governor's Office of Business and Economic Development (GO-Biz) offers extensive information on state, local, and federal permit requirements. For a listing of their assistance centers, visit GO-Biz.

Environmental Fee Topics

Below are industry topics for the Environmental Fee Program.

Parent Corporations/Organization Requirements

Parent corporations/organizations should contact their wholly-owned subsidiaries to find out if they are registered with CDTFA. All parent and subsidiary organizations must separately register and file returns for the Hazardous Waste Environmental Fee.

Professional Employment Organizations (PEO) are Employers

Both DTSC and the Employment Development Department (EDD) recognize Professional Employment Organizations (PEOs) as employers. PEOs, such as a temporary employment agency, are responsible for paying the Hazardous Waste Environmental Fee for any employees reported under their EDD number.

Payroll Agencies

Payroll Agencies must separately apply for third-party access to each of their client's accounts in order to report and pay the Environmental Fee on behalf of their clients. Access may be requested through our online services system.

Visit our Tutorials page to view the video tutorial How to Create a Username and Password For a Third Party and Request Access to an Account.

Standard Industrial Classification (SIC) codes

Standard Industrial Classification (SIC) codes have been established by the U.S. Department of Labor and are used to designate the activities of business operations. Only organizations in specific SIC codes are exempt from the hazardous waste environmental fee (HSC section 25205.6).

Determining number of employees

The number of qualifying employees is determined by counting the number of employees who are employed in California more than 500 hours during a calendar year. This includes vacation, sick leave, and holidays for which an employee is paid during their employment.

If a person terminates employment, vacation, sick leave, holidays or other severance pay are not included when calculating the number of hours.

An employee's paid travel time should be included in the calculation of the 500-hour threshold that an employee is employed.

For example, travel time on an airplane should be included in the calculation of hours paid if the employee is paid for that time.

No prorating for hours worked in-state and out-of-state

If the organization reports employees to EDD in California, the hours worked in California should be calculated based on the total number of hours paid by the organization, regardless of the number of hours the employee works in California or out-of-state. The number of hours should not be prorated between in-state and out-of-state to determine hours worked.

If an employee is reported to another state's EDD, that person is not considered employed in California regardless of the number of hours the employee actually works in this state.

Facility Fee Topics

Below is industry topic for the Facility Fee Program.

Household hazardous waste collection facilities

The exclusion for household hazardous waste collection facility was made inoperative on July 1, 2022. However, household hazardous waste collection facilities that are authorized under Permit by Rule, Conditional Authorization, or Conditional Exemption by the local Certified Unified Program Agencies (CUPA), are not subject to the facility fee if they paid the local CUPA fees.

Generation and Handling Fee Topics

Below are industry topics for the Generation and Handling Fee Program.

Facility operators are responsible for the generation and handling fee

Starting January 1, 2022, facility operators who generate five or more tons of hazardous waste at any site during a calendar year are subject to the hazardous waste generation and handling fee, even if they have paid a hazardous waste facility fee pursuant to HSC section 25205.2 or received a credit under HSC section 25205.2(i). (HSC section 25205.5)

However, a facility operator that is issued a hazardous waste facility permit from DTSC and that pays the annual facility fee, as specified in HSC section 25205.2, may deduct, from the amount of hazardous waste subject to the generation and handling fee, the amount of waste that is stored, bulked, or transferred from that facility to another authorized facility for management according to HSC section 25205.5(a)(4).

Prior to January 1, 2022, facility operators who generated five or more tons of hazardous waste at any site during a calendar year and who had paid a hazardous waste facility fee prior to January 1, 2022, were exempt from the hazardous waste generator fee.

Imported Waste into California

From January 1, 1996 through December 31, 2021, any person transporting, importing, or receiving non-RCRA hazardous waste imported into California for purposes of treatment, recycling, or disposal is exempt from the payment of the generator fee imposed pursuant to HSC section 25205.5.

On and after January 1, 2022, for hazardous waste imported into California for purposes of treatment, recycling, or disposal, the operator of the facility receiving the imported hazardous waste shall register for a generation and handling fee account (in addition to a facility fee account) and pay the applicable generation and handling fee. Please see HSC section 25205.22 for details.

Hazardous waste generator fee paid to local agencies (CUPA)

Any hazardous waste generator fee paid to your local agency (city or county), as part of the Certified Unified Program Agencies (CUPA), is a separate fee from the state hazardous waste generator fee or the generation and handling fee. If you generate hazardous waste in an area that has a CUPA fee, you are responsible for and must pay both the local hazardous waste generator fee and the state hazardous waste generator fee/generation and handling fee. For more information, visit the Department of Toxic Substances Control's CUPA webpage.

Consolidated manifesting (Milk Run) haulers and transporters

Consolidated manifesting, formerly known as modified manifesting or milk running, allows certain registered hazardous waste transporters to combine specified wastes from multiple eligible generators on a single manifest, rather than using a separate manifest from each generator. For more information on consolidated manifesting, please see HSC section 25160.2(c) and visit the Department of Toxic Substances Control's website.

Hazardous waste identification numbers (EPA ID numbers)

The Department of Toxic Substances Control (DTSC) issues state EPA ID Numbers for generators, transporters, and treatment, storage, and disposal facilities that handle hazardous wastes not regulated under the Resource Conservation and Recovery Act (RCRA). For more information on state EPA ID numbers or federal EPA ID numbers see DTSC's website on Applying for a Hazardous Waste Identification Number or call 1-800-618-6942 for more information.

Treated wood waste (TWW)

Treated wood waste (TWW) is considered to be hazardous waste for the proposes of the hazardous waste generation and handling fee and should be included in the calculation of total tonnage of waste subject to the fee, regardless of whether the waste is shipped using a hazardous waste manifest or other shipping document.

All TWW handlers and generators that generate more than 10,000 pounds (5 tons) in any calendar year shall obtain an EPA number from DTSC and register with CDTFA for a generation and handling fee account. Please see DTSC's website for more information on TWW.

Activity Fee

Effective September 13, 2016, DTSC is responsible for assessing and billing the Hazardous Waste Activity Fees (Senate Bill 839).

Activity fees are assessed for permit applications, permit modifications, renewals of permits, requests for variance or site mitigation assessments or other activities, as notified by DTSC.
