Very Small Quantity Generator Program


Very Small Quantity Generator (VSQG) 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.

Legal Requirements

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.

If you have any questions or need further information,  please call (650) 655-6217 or email us at


Request a VSQG Appointment

VSQG Collections are held at our San Mateo facility and are by appointment only. Appointments are available on the first and third Wednesday of each month between 9:00 a.m. and 1:00 p.m.

Online requests for appointments can be made here. 

To request an appointment: 

1. Determine that your business qualifies as a VSQG by only generating less than 100 kilograms (about 220 pounds or 27 gallons) of hazardous waste per month.


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.

If you only have paint to dispose of, please visit to find a drop-off site near you to recycle your leftover and unwanted paint.


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.
