HB 882 prevents Tennessee's Department of Environment and Conservation from regulating certain farming activities on small properties. Specifically, it exempts topsoil handling, rock removal, and pond construction on properties under three acres that have "greenbelt" classification under state law. This exemption applies only to land already designated as agricultural, forest, or open space under the 1976 Agricultural, Forest and Open Space Land Act. The bill would take effect on July 1, 2025, changing how farming operations are regulated on qualifying small farms.
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 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.
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 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 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 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.
