The West Contra Costa County Household Hazardous Waste Facility is not an asbestos disposal site for businesses.

However, residents may dispose of incidental asbestos from homeowner projects for a one-time only basis, with the following requirements:

  • Only up to three (3) quantity 32-gallon bags, all clearly labeled as “Asbestos”;
  • Asbestos must be double bagged and wetted down;
  • Bags may not be over 24” in length; and
  • Each bag can only be 25 pounds or less.

As a resident, if you have more to remove or dispose of than alllowed, be sure to contact a trained and accredited asbestos professional to remove it and dispose of it properly. Don’t disturb or attempt to remove on your own.
