Wood often used for fencing and decks is no longer being accepted for disposal at the Kiefer Landfill.

Due to changes in state law, treated wood waste will no longer be accepted at Kiefer Landfill, effective Jan. 1, 2021.

Nor will it be accepted in the bulky waste pickup service for residents who receive curbside garbage collection from Sacramento County. Treated wood waste has never been accepted at Sacramento County’s North Area Recovery Station.

Treated wood, or pressure-treated wood, has been treated with a chemical preservative to protect it from bugs, fungi and environmental conditions that can lead to decay. Indicators that wood has been treated include: an ink stamp on the wood or an end tag or small, closely spaced cuts that resemble staple holes on the surface of the wood.

Wood fencing and decking comprise the most common treated wood waste materials generated by homeowners. Other examples of treated wood are creosote-treated lumber that is used for guardrail posts, railroad ties and pilings.

Surface-applied coatings, such as paint, varnish and oil stain, are not considered chemical preservatives. Painted wood will continue to be accepted at Kiefer Landfill, the North Area Recovery Station and in residential bulky waste pickups.

As of Jan. 1, treated wood waste must be managed as hazardous waste. To dispose of such material, contact a hazardous waste company that specializes in the management of hazardous waste material. For more information, visit the SacGreenTeam website or email
