As of 1/1/21 Treated Wood Waste is Considered Hazardous Waste

Effective 1/1/2021, ALL COUNTY Waste Facilities will NO LONGER ACCEPT Treated Wood Waste (TWW) . We are NOT permitted to accept this HAZARDOUS WASTE MATERIAL. The closest location to accept this material as of Jan 1st, 2021 is BUTTONWILLOW CA Landfill.  For now, we are recommending customers store TWW on their property until further notice as the County is working on potential avenues (waivers) for future relief. We are monitoring updates closely and we will continue to work together on this situation as best we can. More information can be found here.

There are 2 main groups of TWW (water based & oil based). To simplify the classification of what does NOTqualify as TWW:

  • Natural wood with NO chemical preservatives
  • Natural wood coated in paint or surface finish such as lacquer, shellac, polyurethane and varnish

What is treated wood? Treated wood is wood that has gone through a treatment process with chemical preservatives to protect it against pests and environmental conditions. Typically, treated wood is used in exterior applications where ground or water contact is likely. Treated wood means wood that has been treated with a chemical preservative for purposes of protecting the wood against attacks from insects, microorganisms, fungi, and other environmental conditions that can lead to decay of the wood, and the chemical preservative is registered pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. Sec. 136 et seq.). These preservatives often include one or more of the following constituents: arsenic, chromium, copper, pentachlorophenol, and creosote.
