The Department of Toxic Substances Control (DTSC) has is sued a variance to Burrtec Waste Industries to accumulate and transport treated wood waste to an authorized handler or disposal facility. Operations related to treated wood waste will be consistent with previous treated wood waste activities conducted by the applicant. The variance allows treated wood waste to be managed under procedures different from, but equally protective to human health and the environment to, the provisions of California Health and Safety Code (HSC) Articles 6, 6.5 and 9 of Chapter 6.5 and California Code of Regulations (CCR), Title 22, Division 4.5, Chapters 12, 13, 14, 15, 16, 18, and/or 20. Under the terms and conditions of Variance TWW-2021-HT-00433, Burrtec Waste Industries will ensure the treated wood waste will be appropriately managed. Treated wood waste is a fully regulated California-only hazardous waste because it exhibits the hazardous waste characteristic of toxicity. From 2007 to December 31, 2020, treated wood waste was managed under alternative management standards, established in 22 CCR 67386. The legislation that authorized the alternative management standards for treated wood waste expired on December 31, 2020. Without the issuance of the variance, Burrtec Waste Industries would be required to register as a hazardous waste transporter with DTSC and manifest treated wood waste as a hazardous waste prior to disposal at a hazardous waste disposal facility. Burrtec Waste Industries operates a transfer station. Under the variance, the authorized handler-transporter may collect, accumulate, and transport treated wood waste from generators, transporters, and/or handlers to authorized handler and/or disposal facilities. Operations generally include loading and unloading operations and shipping treated wood waste along existing transportation routes. Accumulation of treated wood waste includes taking appropriate precautions to prevent unauthorized access to and prevent leaching to the environment of the treated wood waste. The variance will expire on October 31, 2021 with possibility of extension for an additional six months.
