Safe Waste Disposal
Household hazardous waste events (HHW) may be canceled due to poor air quality.
As of June 4th, 2020 only HHW events in San Mateo have resumed. HHW events in additional locations will resume when all safety protocols for both staff and the public can be put in place.
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.
