Treated Wood

Illegal in Garbage, Recycling & Drains
Hazardous Waste

Treated wood is NOT accepted at the Devlin Road Transfer Station, or at any local landfills. 

It currently must be disposed of at an authorized hazardous waste landfill (the nearest is Buttonwillow Landfill outside of Bakersfield), and may only be transported by a registered hazardous waste hauler. 

California is currently developing new guidelines for disposal of treated wood, and the Department of Toxics Substances Control (DTSC) is recommending that generators of treated wood waste keep it stored safely onsite until the new program is in place (probably March/April 2021). 

In the meantime, Treated Wood (up to 3′ long) is now accepted at the Napa-Vallejo Hazardous Waste Facility. Drop off is no charge for residential customers, but there is a limit of 125 lbs. The rate for commercial customers is $203/foot and the maximum per month is 220 lbs – appointments are required.   

Please see the DTSC Treated Wood Waste page for more info and updates.

Never Burn Treated Wood

Chemicals such as creosote are used when treating wood, which creates toxic ash and emissions when burned. These particles lodge in soil and groundwater and take many years to break down, so never burn wood if you think it has been treated.

Take Care With Sawdust

Avoid breathing in sawdust from treated wood, and do not add it to compost or scatter on the ground.

Choose a Different Wood

Redwood and cedar are both naturally pest-resistant. Suppliers are also starting to offer more non-toxic treated wood options.
