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.
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.
HB 1112 makes it a Class A misdemeanor to intentionally inject, release, or disperse chemicals into Tennessee's atmosphere with the purpose of altering weather, temperature, or sunlight intensity. It also criminalizes supplying materials for such activities. The law directly affects individuals or entities conducting weather modification within Tennessee, imposing a $100,000 fine per violation in addition to misdemeanor penalties. Enforcement will be handled by state agencies and prosecutors investigating credible reports of violations. The bill amends Tennessee Code sections governing weather modification and criminal penalties, effective 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.
SB 702 creates the "Climate Resiliency Fund" to finance projects addressing climate change impacts in Tennessee. It requires fossil fuel businesses (coal, oil, gas) operating between 1995 and 2025 to pay cost recovery fees based on their greenhouse gas emissions into the fund. The fund will support climate adaptation projects like flood protections, infrastructure upgrades, and healthcare programs, with priority given to communities designated as "environmental justice focus populations" (low-income, high-minority, or limited English proficiency areas). The bill defines specific eligible projects, including nature-based solutions, stormwater system improvements, and resilience planning for vulnerable infrastructure.
