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.
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 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.
SB 283 would remove a renewal fee requirement for septic system installers in Tennessee. Specifically, it amends state law to prevent the department from requiring installers in good standing to pay a fee when renewing their license, while maintaining the initial fee needed to obtain the license. This change directly affects current and future licensed septic system installers who must renew their credentials. The bill is scheduled to take effect on July 1, 2025.
