However, TWW will still be accepted from commercial customers without a DTSC variance but per regulation, a report of the commercial customer's information will need to be submitted to the State of California. Residents self-hauling TWW will not require a variance.

Commercial customers can find out more information about DTSC and TWW variances at dtsc.ca.gov.

Note: The statute (HSC 25150.7) and regulations (22 CCR 67386.1 et seq.) that allow treated wood waste to be handled with alternative management standards are due to expire after December 31, 2020. After that date, all hazardous treated wood waste (not exempted by HSC 25143.1.5 as utility generated) managed in California will have to be stored and manifested as hazardous waste and transported to class I hazardous waste landfills for disposal.

What is Treated Wood Waste?

TWW comes from old wood that has been treated with chemical preservatives. These chemicals help protect the wood from insect attack and fungal decay while it’s being used. Fence posts, sill plates, landscape timbers, pilings, guardrails, and decking, to name a few, are all examples of chemically treated wood.

Is Treated Wood Waste Toxic?

TWW contains hazardous chemicals that pose a risk to human health and the environment. Arsenic, chromium, copper, creosote, and pentachlorophenol are among the chemicals used to preserve wood and are known to be toxic or carcinogenic. Harmful exposure to these chemicals may result from touching, inhaling, or ingesting TWW particulate (e.g., sawdust and smoke).

Treated Wood Waste is accepted at many Disposal Sites for a Fee. Treated wood waste is not recycled. There are quantity restrictions at some locations. Go to the Disposal Sites page to determine the acceptance criteria for each location.
