Very Small Quantity Generator Program
Some businesses generate very little hazardous waste and may be eligible to participate in the Very Small Quantity Generator (VSQG) Program. The Program is designed to provide an inexpensive hazardous waste disposal option to these companies, non-profits, and other entities instead of contracting with a commercial hazardous waste management firm.
The Program operates by appointment only.
Are you a VSQG?
A VSQG is any business that generates less than 100 kilograms (about 220 pounds or 27 gallons) of hazardous waste per month. Typical VSQG businesses include painters, print shops, carpenters, property managers, and many others.
Some businesses do not generate waste on a regular basis, but do have paint or other wastes lying around. So, even if you want to “clean up” the office, you may generate small amounts of hazardous waste. Such businesses are also considered a VSQG.
Who may Participate?
Only qualifying VSQG businesses operating within San Mateo County may participate in the VSQG collection events. Businesses that generate more than 100 kilograms of hazardous waste per month cannot participate. If you fall into this group, contact an Inspector in the Hazardous Waste Program at (650) 372-6200 or see other options below.
Accepted Wastes and Costs
The cost of disposal depends on the type and amount of the waste you have. The fees charged are pro-rated on a per unit basis, and do not include other related costs that the County may incur. For the most part, these fees will be considerably lower than that of a licensed commercial hazardous waste hauler.
Wastes accepted and associated costs are listed in the VSQG Fee Schedule. Please note that the container size of the waste must not be larger than 5-gallons total.
Waste in a container that is larger than 5-gallons in size, maximum, is not accepted.
The following list of wastes that are not accepted by the program:
- Radioactive Wastes
- Electronic Wastes and Appliances
- Compressed Gas Cylinders (except propane)
- Explosives and Ammunition
- Medical/Biological Wastes
- Sharps & Needles
- Pressure Treated Wood

of. Please include what the waste is, the container size, and
how much you have, and also include what appointment day and
time you would like:

- Have your EPA ID number and waste inventory list ready and call toll free 1-800-207-8222 (ask for San Mateo County Customer Service Representative); email cesqgsanmateo@Stericycle.com or fax 1-916-351-1707.
- Staff will estimate your cost of disposal and set the appointment for you. If your desired appointment day and time is not available, you will be contacted with other options.

If your business qualifies as a VSQG, certain legal requirements will apply to your business, including hazardous waste storage amounts, transportation limits, and State EPA Identification numbers. Please contact an Inspector in the Hazardous Waste Program at (650) 372-6200 for these and other legal requirements.
