Variance TWW-2021-LG-00365 to Allow the Generation, Accumulation, and Transport of Treated Wood Waste under Alternate Procedures by Port of San Francisco
The Department of Toxic Substances Control (DTSC) has issued a variance to Port of San Francisco (CAC003091512) to generate and accumulate treated wood waste on-site. The applicant may transport the treated wood waste generated on-site to an authorized handler or disposal facility. The treated wood waste is generated as a result of Removal, maintenance and repair or marine piers and related structures. 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-LG-00365, Port of San Francisco will ensure the treated wood waste will be appropriately managed. The treated wood waste management activities are part SFPort Pier 52 dilapidated apron and pile removal and Port Pier 50 south apron and pile repairs. 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, Port of San Francisco 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. Port of San Francisco is a Trustee and manager of the Port of San Francisco, which is a 7.5-mile waterfront property generally extending from Hyde Street Harbor, in Fisherman's Wharf, to Heron's Head Park, in the Bayview/Hunter's Point area.. The applicant previously conducted treated wood waste management activities under the now expired alternative management standards established at 22 CCR 67386. Under the variance, the authorized large quantity generator may generate, accumulate, treated wood waste on-site. The generator may transport the treated wood waste generated on site to authorized handler and/or disposal facilities. Operations generally include loading and unloading operations and shipping treated wood waste along existing transportation routes. Accumulation and transport 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 November 3, 2021 with possibility of extension for an additional six months.
