Document Type
NOE - Notice of Exemption
Document Description
The Department of Toxic Substances Control (DTSC) has issued a variance to City of Clovis (CAH111000512) to receive and dispose of treated wood waste from generators, transporters, and/or handler facilities. 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-DF-00580, City of Clovis 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, City of Clovis would be required to seek a permit as a hazardous waste disposal facility. City of Clovis owns and operates the City of Clovis landfill. The City's Public Utilities Department, Solid Waste Division monitors and assures landfill compliance. The City of Clovis landfill is not a public landfill and only accepts waste from City of Clovis residents and businesses hauled by City of Clovis garbage trucks. Under the variance, the Facility will accept treated wood waste from generators, and authorized handlers and/or transporters for disposal, however it will be managed as a California hazardous waste, under authority of HSC 25200 et seq. Operations generally include unloading and disposal of treated wood waste within City of Clovis Landfill which has a Geocomposite, 60 mil HDPE, double sided textured geomembrane, Geosynthetic clay liner, prepared subgrade. Acceptance and disposal of TWW will be consistent with hazardous waste management and disposal standards specified in the variance. The variance will expire on December 13, 2021 with possibility of extension for an additional six months.
