Solid Waste Disposal - As introduced, prohibits municipalities, counties, and other political subdivisions of this state from disposing, or contracting for the disposal of, solid waste in a landfill located outside their territorial boundaries unless the host county or host municipality in which the landfill is located has entered into a host community agreement approving such disposal; applies to all contracts entered into for the disposal of solid waste on or after July 1, 2026. - Amends TCA Title 5; Title 6; Title 7 and Title 68, Chapter 211.

SB 2551 requires Tennessee counties and municipalities to obtain a written "host community agreement" from the local government where a landfill is located before disposing of solid waste outside their own boundaries. This applies to all new waste disposal contracts entered after July 1, 2026, and mandates agreements include details like duration, fees, environmental protections, and truck routes. Existing contracts in place before July 2026 are exempt until their expiration. The law aims to ensure local communities consent to accepting waste from other jurisdictions, with the state department verifying agreements before issuing disposal permits.
