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.
SB 438 creates an advisory task force to examine solid waste management issues in Tennessee and authorizes the Department of Environment and Conservation to accept voluntary contributions and apply for private grants for recycling infrastructure, recycling projects, and composting initiatives. The bill requires the department to publish a report on its website regarding these efforts. It amends multiple sections of Tennessee law related to waste management, including provisions for grant funding and reporting. The bill became effective on May 9, 2025.
SB 670 requires Tennessee's Department of Environment and Conservation to annually report on compensatory mitigation for aquatic permits to state officials, and establishes four regulatory categories for isolated wetlands. It also adds a new rule preventing the state from classifying property as a wetland unless it meets federal standards. The bill directly affects developers seeking permits for wetland alterations and state agencies managing environmental regulations. Key changes include mandatory reporting to the governor and legislature, and aligning state wetland rules with federal classifications, effective July 1, 2025.
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.
HB 612 modifies Tennessee's water pollution permitting rules to exempt certain applicants from requiring compensatory mitigation. Specifically, if a project applicant would qualify for a general permit (covering routine activities) but is disqualified solely due to the project's size, the Department of Environment and Conservation must exempt them from needing to replace lost wetland or aquatic habitat. This applies to all areas covered by aquatic resource alteration permits, not just wetlands. The change takes effect July 1, 2025, streamlining permits for smaller projects that otherwise meet general permit criteria. This directly affects developers, contractors, and landowners seeking permits for water-related projects.
HB 125 modifies Tennessee's local parks land acquisition grant program by reducing the required local match for projects in Appalachian Regional Commission-designated distressed or at-risk counties. Specifically, it changes the rule from requiring a 100% local match (equal to the grant amount) to a 25% local contribution for these counties. This applies to county or municipal governments receiving grants under TCA Section 67-4-409 for projects located in designated areas. The bill takes effect October 1, 2025, easing financial burdens for local governments in economically challenged regions seeking park land acquisitions.
SB 880, effective July 1, 2025, requires Tennessee environmental agencies to base new regulations on "best available science" for drinking water, air quality, hazardous substances, and waste handling. It prohibits agencies from adopting stricter rules than federal standards (or new rules without federal equivalents) unless the science is reliable, unbiased, peer-reviewed, and demonstrates a causal link between exposure and human health harm. The law applies only to new regulatory actions after July 2025, not existing rules or federal compliance requirements. It directly affects agencies like the Tennessee Department of Environment and Conservation when creating new environmental standards.
SB 113 amends Tennessee law to give the state Department of Environment and Conservation commissioner authority to issue variances (exceptions) for subsurface sewage disposal systems, overriding stricter local requirements in certain cases. It directly affects county health departments implementing these systems and property owners needing sewage solutions. The key provision allows the commissioner to grant variances that supersede local rules, while requiring these variances to be recorded with the county register of deeds. This change streamlines state oversight for sewage systems without requiring local approval.
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 126 revises Tennessee's state natural areas by updating acreage descriptions for existing protected lands and designating four new natural areas. It increases protected acreage for sites like Barnett's Woods (from 40 to 156 acres) and adds new areas including Clifty Creek Gorge (89 acres protecting the federally threatened Virginia spirea), Rocky Hill (1 acre safeguarding the endangered running glade clover), Union Grove (59 acres preserving the Tennessee trillium), and Versailles Knob (40 acres protecting Braun's Rockcress). The bill directly affects conservation efforts by expanding legal protections for specific endangered species and habitats across Morgan, Rutherford, and Hamblen counties. Enacted on April 11, 2025, it formalizes these land designations without introducing new funding or regulatory requirements.
