Treated Wood Waste


Effective January 1, 2021:  Treated Wood Waste (TWW) is hazardous waste and must be managed, stored, and transported as such.  TWW will need to be disposed of at a Class I hazardous waste landfill.  The City of Berkeley Transfer Station, and the Alameda County Household Hazardous Waste facilities, will not be accepting TWW.  You will need a Hazardous Waste contractor to properly transport and dispose of this material.

TWW is wood treated with hazardous chemical preservatives to prevent decay. Examples of treated wood include railroad ties, telephone poles, fence posts, decking, landscape timbers, and tree stakes. Treated wood is often identified by staining from treatment (often light green) and/or incision marks on lumber.

 For more information on how to identify TWW go to page 4 of: https://dtsc.ca.gov/wp-content/uploads/sites/31/2017/05/TWW_GuidanceDisposal.pdf

For information on required hazardous waste management standards please go to:  https://dtsc.ca.gov/accumulating-hazardous-wastes-at-generator-sites/

TWW generated from power and telephone utilities is exempt from these requirements.
