Effective Thursday, July 1st and until further notice, HWMA is pleased to announce we were granted a 6-month variance waiver from the Department of Toxic Substance Control (DTSC) to allow the acceptance of Treated Wood Waste (TWW) at the Hawthorne Street Transfer Station’s Tip Floor. This waiver comes after DTSC banned the disposal of TWW at California landfills on January 1, 2021.
This waiver allows HWMA to accept and dispose of TWW to permissible landfills with proper lining and environmental controls. 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.
DTSC requires that in order to transport hazardous waste, such as TWW, persons must either be a registered hazardous waste transporter or have received a variance from DTSC. Further information on obtaining a variance can be found at https://dtsc.ca.gov. This excludes homeowners who self-deliver less than 50 pounds of TWW.
Please review the following TWW guidelines prior to visiting HWMA’s Transfer Station:
