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.
HB 896, the "Sound Science in Regulations Act," prohibits Tennessee environmental agencies from creating new rules on drinking water, air quality, hazardous substances, or waste handling unless they meet strict scientific standards. It requires agencies to base regulations on "best available science" that is reliable, unbiased, and published in peer-reviewed journals with independent verification. The law applies only to new rules stricter than federal standards, effective July 1, 2025, and excludes existing rules or those required by federal law. This directly affects agencies like the Tennessee Department of Environment and Conservation when developing new environmental regulations.
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 199 gives Tennessee's environmental commissioner authority to issue variances (exceptions) to subsurface sewage disposal rules, overriding stricter local requirements. This directly affects property owners needing sewage systems and county health departments implementing these rules. The bill requires any granted variance to be recorded with the county register of deeds. It amends state law to clarify the commissioner's role in approving these exceptions while ensuring public records are updated.
HB 1139 clarifies monitoring requirements for facilities that install water softening systems. If such a system causes a facility to meet Tennessee's definition of a public water system under the Safe Drinking Water Act, the facility must test water hardness, alkalinity, and pH quarterly, and sodium annually. Results must be reported to the Department of Environment and Conservation within 15 days of each reporting period. The bill specifically excludes facilities that only install softeners from being classified as public water systems, but if they meet the definition due to the softener, they must comply with these testing rules.
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.
HB 801 removes a specific energy efficiency requirement for low-sloped roofs in Tennessee. It amends state law to clarify that the International Energy Conservation Code's roof solar reflectance and thermal emittance rules no longer apply to such roofs starting July 1, 2025. This change directly affects builders, developers, and homeowners constructing or renovating low-sloped roofs across Tennessee. The bill achieves this by adding a new provision to Tennessee Code Title 68, Chapter 120, eliminating the requirement without creating new rules. The law became effective April 3, 2025, with the policy change taking effect on July 1, 2025.
