Effective January 1, 2025, Chiquita Canyon Landfill will be closed for the acceptance of waste. Chiquita Canyon, LLC will continue to manage the landfill, including addressing the elevated temperature landfill event that is affecting the northwest corner of the landfill, as well as closure and post-closure activities. While active waste disposal operations will close, we remain committed to working with federal, state and local regulators on the ongoing reaction mitigation efforts.
