    • Unlabeled containers with known contents should be labeled with the product name or classification
    • No containers greater than 5 gallons
    • If container is very rusty or cracked, transfer to another container and label it or place it in another secure container
    • Place wastes in boxes and surround with newspaper or other material so that containers do not move during transport

  • We can only accept the wastes that have been pre-approved.
  • Prior to arrival at the facility, you will need to bring the following items:

What information should I have when I call?

A clear, complete description of your hazardous waste is necessary to determine whether the waste can be accepted into the Small Quantity Generator Program. Explosive (or potentially explosive), infectious, radioactive, are not acceptable in any case.A complete inventory of the hazardous waste you wish to dispose of will be required at the time you pre-register in order to price your waste. Hazardous waste brought to the program must be described by at least the following:

  • Name, address and phone number of your company.
  • Figures for how much waste is generated per month and per year.
  • Chemical name or trade name of the waste.
  • Percentages of chemical constituents in the waste.
  • Process generating waste and possible contaminants
  • Size, type and number of containers to be brought in.

Material Safety Data Sheets (MSDS) are often your best source of information regarding the potentially hazardous products you use. An MSDS will list the hazardous constituents of each product and are available from product suppliers. If you have an MSDS for the hazardous product or waste you want to dispose of, have it handy when you call in to pre-register and bring a copy with you when you drop off your waste.If you do not have an MSDS for your hazardous product or waste, describe the waste’s characteristics, uses, and origin to the SQG coordinator and mark this information on the product container. If the waste is still in its original container, keep it there because information on the container is likely to help with the waste description. If the waste is not in its original container, label the container clearly with the chemical contents or bring the original container along with you.Unknown wastes cannot be accepted under this program, but may be resubmitted once a satisfactory description or laboratory analysis is available.

What if I have too much waste to qualify for the SQG Program?

If you generate per month more than the amounts of waste listed above, you are considered a regulated generator. You may not participate in this Small Quantity Generator Program. For information on how to get rid of your hazardous waste, call a local hazardous waste management company, or the State Department of Toxic Substance Control at (916) 255-3545.

Do I need a state generator identification number?

Yes, in the state of California, every business which generates any amount of hazardous waste is required to have a Generator Identification Number. This can be obtained by submitting an online application with the State Department of Toxic Substance Control. For more information on obtaining an identifction number, call 1-800-618-6942. You should have a generator number and provide it to the SQG Coordinator before bringing your waste to the collection site.

What paperwork do I need to fill out?

When you arrive on your designated drop-off day and time, you, as a company representative, will be asked to sign a completed Check-in Receipt and Certification Statement. This is used to verify that all of the information on the completed form is accurate to the best of the representative’s knowledge, and to verify that the representative and the company understand and meet the regulatory requirements for qualification as a Small Quantity Generator. The check-in attendant will complete the waste description portion of the Check-in Receipt. A copy of this form will be returned to you as certification of proper waste disposal and cash receipt.

Where can I learn more? Much of the information referenced in this summary is taken from the California Code of Regulations and the Federal Code of Regulations. We encourage you to acquire these regulations and other educational material from the California State Department of Toxic Substance Control at (916) 255-3545.
