HB 1133 amends Tennessee's tax code to allow nuclear energy production facilities to claim pollution control tax credits for specific machinery and equipment, expanding an existing program previously limited to wind energy. This change directly affects nuclear power plants in Tennessee by providing them with a new financial incentive to invest in pollution control technology. The bill modifies Section 67-4-2004(9)(A) of the Tennessee Code to explicitly include nuclear facilities alongside wind energy sources. The law takes effect on July 1, 2025.

HB 541, now law as Public Chapter 437, requires Tennessee's environmental agency to align state wetland regulations with federal standards. It prohibits the state from classifying or regulating property as a wetland unless it is federally classified as such, directly affecting property owners and developers seeking permits. The bill also mandates annual reports to state leaders on compensatory mitigation (replacing damaged wetlands) for permits issued the previous year. Additionally, it establishes four new categories for regulating isolated wetlands, though specific definitions aren't detailed in the provided text. The law aims to reduce regulatory overlap between state and federal wetland rules.

SB 1274 updates Tennessee's environmental fee structure and regulates coal combustion residuals (like ash from power plants). It increases fees for regular landfill permits ($10,000) and annual maintenance ($15,000), while excluding coal ash disposal units from these charges. The bill requires new liners and caps for coal ash disposal facilities (except for specific uses like agricultural or engineering applications) and allows the Department of Environment and Conservation to recover regulatory costs for coal ash units through capped fees. These changes directly affect power plants, waste management facilities handling coal ash, and environmental regulatory programs.

SB 258 clarifies that facilities installing only water softening devices (for hard water) do not become public water systems under Tennessee law, even if the device causes them to meet the definition. It specifically excludes such softening systems from public water system requirements, meaning these facilities are not required to monitor water quality unless they otherwise qualify as a public water system. If a softening system causes a facility to meet the public water system definition, it must monitor hardness, alkalinity, pH quarterly and sodium annually, reporting results to the Department of Environment and Conservation within 15 days of each quarter. The bill amends Tennessee Code Annotated Title 68 and takes effect July 1, 2025.

HB 1112 makes it a Class A misdemeanor to intentionally inject, release, or disperse chemicals into Tennessee's atmosphere with the purpose of altering weather, temperature, or sunlight intensity. It also criminalizes supplying materials for such activities. The law directly affects individuals or entities conducting weather modification within Tennessee, imposing a $100,000 fine per violation in addition to misdemeanor penalties. Enforcement will be handled by state agencies and prosecutors investigating credible reports of violations. The bill amends Tennessee Code sections governing weather modification and criminal penalties, effective July 1, 2025.
