Business Hazardous Waste

Body: 

HWMA's Household Hazardous Waste (HHW) program is open to businesses that are small quantity generators. 'Businesses' include landlords, nonprofits, & churches.

Customers are asked to respect social distancing at all times (remain six feet apart from other customers and employees), and to wear face masks at all times while on site.

PLEASE NOTE: By law, all businesses must call ahead to make an appointment. To schedule an appointment call (707) 441-2005. Appointments may be made Monday through Saturday, from 8:00 a.m. to 3:00 p.m. The facility is closed from 12:00 p.m. to 1 p.m. daily.

Do I Qualify?

If you produce 220 pounds or 27 gallons or less of hazardous waste in any month you qualify for this program. If you produce more than this quantity, you are considered a large quantity generator and must contact a hazardous waste transporter for proper handling, transport and disposal of your hazardous waste.

5 Gallon Size Container Limit - We can only accept containers that are up to 5 gallons in size. If you current container size is too large, follow these tips:

  • Get containers that are 5-gallons in size, such as a paint bucket with a lid.
  • Transfer waste from your larger container into the smaller one. Use as many smaller containers as needed.
