Solid Waste Disposal - As introduced, creates exception to the state regulation of biosolids by authorizing the legislative body of Grundy County to regulate such activities. - Amends TCA Title 5; Title 68, Chapter 211; Title 68, Chapter 221 and Title 69.

HB 1122 modifies Tennessee law to allow Grundy County (population 13,500-13,550 per 2020 census) to regulate the land application of treated sewage sludge (biosolids) instead of state agencies. The bill amends multiple code sections to transfer authority from state regulators to Grundy County's legislative body for this specific activity. It does not affect other counties or other waste management regulations. The change applies only to biosolids land application, leaving all other solid waste rules unchanged. This is a targeted regulatory shift for one county, not a broad policy change.
