Proper Disposal of Household Hazardous Waste
Chicago Grade Landfill features a Household Hazardous Waste (HHW) collection unit on the premises for safe disposal of common hazardous waste materials. HHW is collected from the public by Integrated Waste Management Authority (IWMA) staff at the HHW collection facility.

The maximum amount you can drop off at one time for free is 15 gallons or 125 pounds.  There is no charge to SLO County residents ($20 charge applies for residents dropping off more than one TV/computer monitor).

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 collection 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. Empty containers may be discarded with your trash.

We accept all household hazardous waste except radioactive materials, explosives, or biomedical waste such as sharps, lancets or needles.  In addition, the facilities are open to small businesses, but you must first call 1-800-400-0811.

Hours of Operation
The HHW Collection Center hours are Saturday from 11 am to 3 pm. The IWMA sets the hours for the HHW collection center, therefore these hours are subject to change and not within our control. Feel free to call ahead at 805-466-2985 ext. 10 to confirm the availability of the HHW Collection Center.

Household Hazardous Waste for Small Businesses
If you are a conditionally exempt small business and generate less than 27 gallons or 220 pounds of hazardous waste per month, we can provide hazardous waste collection and disposal service for you.  Call 1-805-782-8530 for more information.
