The alternative management standard (AMS), which allows waste haulers to accept treated wood waste (TWW) from residential and commercial customers, expired on December 31, 2020. 

As of January 1, 2021, waste haulers in the County of Marin cannot accept TWW at their facilities, in their debris boxes, and in the garbage, recycling, or composting bins as treated wood is now considered hazardous waste.

The Department of Toxic Substances Control (DTSC) is working on some variances that could allow some facilities to receive TWW. Until the variances are applied, DTSC suggests generators delay removing treated wood if possible or temporarily storing the waste before disposal.

Currently, the Marin Household Hazardous Waste facility cannot accept TWW from residential or commercial generators. Please, do not bring TWW to the facility, and please do not instruct your customers to do so either.

If you must remove any TWW, read the DTSC factsheet to avoid any penalties and get a disposal estimate from an approved hazardous waste hauler. To find more information related to the topic, visit the DTSC website.
