TREATED WOOD WASTE (TWW)
On August 31, 2021, Governor Newsom signed Assembly Bill 332 which adopts new Alternative Management Standards (AMS) for treated wood waste, codified in Health and Safety Code section 25230. As a result, all treated wood waste variances issued by DTSC since March 2021 are now inoperative and have no further effect, as they have been replaced by the AMS.
TWW disposal fees will remain the same and the DTSC still requires the County to collect customer information at the time of disposal.
Treated Wood Waste (TWW) can only be accepted from addresses within Santa Cruz County including: Unincorporated Santa Cruz County, and the Cities of Capitola, Scotts Valley, Santa Cruz, and Watsonville.
All deliveries by generators, handlers, and transporters must be accompanied by a completed Treated Wood Waste Disposal Form.
All generators, handlers, and transporters are required to deliver TWW to the Buena Vista Landfill Tuesday through Thursday and must hand unload TWW into a bin. TWW must be separated from all other waste or the load may rejected. Click Here for the Policy.
Residents may be required to provide name, address, and phone number. Residents must hand unload TWW into a bin at both the Buena Vista Landfill (no weight limit at the Buena Vista Landfill) and Ben Lomond Transfer Station (up to 500 pounds for Ben Lomond Transfer Station per day) Monday through Saturday. TWW must be separated from all other waste or the load may be rejected. Click Here for the Policy.
Fact Sheet and Other Information
DTSC has developed a fact sheet to help generators and handlers understand what the new requirements are for the alternative management standards for treated wood waste. A link to the new fact sheet and list of landfills approved to accept TWW are found below:
TWW acceptance is subject to change at any time.
