Household Hazardous Waste

Household hazardous waste should NOT be disposed of in the trash or in the gutter. Hazardous waste disposed of in the trash poses a serious threat of injury to trash collectors and landfill operators. This kind of waste also creates environmental problems when disposed of improperly. For these reasons, disposal of hazardous waste is regulated and improper disposal is illegal. The penalties can be substantial.

Hazardous waste must be disposed of at designated locations and times. There are six household hazardous waste facilities in San Luis Obispo County. All household hazardous waste facilities accept up to 15 gallons or 125 pounds of waste materials free of charge.
