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.
SB 664 modifies Tennessee's water permit rules to exempt certain applicants from compensatory mitigation requirements. If a project applicant is denied coverage under a simplified "general permit" solely because of the project's size (not other factors), the Department of Environment and Conservation must exempt them from needing replacement wetlands or habitat for an area equal to what would be exempt under the general permit. This directly affects developers or landowners seeking permits for activities impacting water resources who are disqualified only by project scale. The change takes effect July 1, 2025, and applies to permits under Title 69, Chapter 3 of Tennessee law.
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.
SB 1277 revises Tennessee’s state natural areas program by adjusting acreage measurements for existing protected lands and designating four new natural areas for conservation. The bill specifically adds Clifty Creek Gorge (89 acres in Morgan County, protecting the Virginia spirea), Rocky Hill (1 acre in Rutherford County, safeguarding endangered plants), Union Grove (59 acres in Hamblen County, preserving the Tennessee trillium), and Versailles Knob (40 acres in Rutherford County, protecting Braun’s Rockcress). It also updates acreage figures for multiple existing sites, such as expanding Barnett’s Woods to 156 acres and Emory River to 2,754 acres. These changes directly affect the state’s conservation efforts by formally protecting specific ecosystems and endangered species under Tennessee’s natural areas framework.
SB 884 clarifies that local governments (like cities or counties) must accept 19 specific energy sources - including solar, wind, nuclear, natural gas, and biomass - as "clean or green energy" when setting requirements for public utilities. It requires these local rules to include all 19 sources as permissible, regardless of whether the government labels the rules as targeting "clean" or "renewable" energy. The bill amends Tennessee law to define "energy project" and "public utility" consistently across multiple code sections. This change ensures utilities comply with local energy rules by using any of the listed sources, without requiring local governments to explicitly classify their requirements as "clean energy" or "renewable energy."
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.
HB 1143 clarifies that local governments (counties, cities) cannot restrict public utilities from using certain energy sources when creating regulations about clean or renewable energy. It requires all local energy requirements to include 19 specific sources as permissible, including solar, wind, nuclear power, natural gas, and biomass - regardless of how the local rule is worded. This directly affects municipal and county regulations governing utility energy sources and ensures utilities can comply by using any of the listed options. The bill amends multiple Tennessee code sections to define "clean or green energy" broadly and makes local rules that exclude these sources legally invalid.
