Bill Summary
Amends the School Code. In provisions concerning radon testing, provides that every school building of a school district that is occupied or will be occupied shall be tested by January 1, 2029 and shall be retested every 5 years thereafter for radon (instead of recommending that every occupied school building of a school district be tested every 5 years for radon). Provides that all new schools of a school district shall be built using radon resistant new construction techniques in accordance with the American National Standards Institute/American Association of Radon Scientists and Technologists CC-1000, Soil Gas Control Systems in New Construction of Multifamily, School, Commercial and Mixed-Use Buildings standard or a successor standard (instead of recommending that new schools of a school district be built using radon resistant new construction techniques, as shown in the United States Environmental Protection Agency document, Radon Prevention in the Design and Construction of Schools and Other Large Buildings). Removes a provision allowing a person to perform radon screening tests without a license. Makes changes concerning the exemption. Provides that if radon is found to exceed specified levels, then the school district shall (instead of may) hire a licensed radon professional to perform confirmatory measurements (instead of to perform measurements before any mitigation decisions are made). Sets forth provisions concerning mitigation. Provides that a school district may use life safety funds, if available, for radon testing and mitigation. Preempts home rule powers.
AI Summary
This bill amends the School Code to strengthen radon testing and mitigation requirements for school districts. It mandates that every school building must be tested for radon by January 1, 2029 and retested every 5 years thereafter, replacing previous language that only recommended testing. The bill requires all new schools to be constructed using specific radon-resistant techniques according to the American National Standards Institute/American Association of Radon Scientists and Technologists standard. School districts are now required to hire licensed radon professionals to perform confirmatory measurements if initial screening tests detect radon levels of 4.0 picocuries per liter (pCi/L) or higher, and must mitigate affected areas within 2 years. The bill removes provisions allowing unlicensed individuals to conduct radon screening and gives school districts the option to use life safety funds for radon testing and mitigation. Additionally, the legislation preempts home rule powers, meaning local governments cannot implement regulations that would reduce the radon protections outlined in the bill. The primary goal is to protect children, teachers, staff, administrators, and visitors from radioactive radon exposure in school buildings.
