(3) At such time as Illinois enters into a Federal-State Agreement in accordance with the provisions of this Act, the Agency shall license and collect license fees from persons operating radiation installations, including installations involving the use or possession of by-product material as defined in subsection (a-5)(2) of Section 4 and installations having such devices or equipment utilizing or producing radioactive materials but licensure shall not apply to any x-ray machine, including those located in an office of a licensed physician or dentist. The Agency may also collect license fees from persons authorized by the Agency to engage in decommissioning and decontamination activities at radiation installations including installations licensed to use or possess by-product material as defined in subsection (a-5)(2) of Section 4. The license fees collected from persons authorized to use or possess by-product material as defined in subsection (a-5)(2) of Section 4 or to engage in decommissioning and decontamination activities at radiation installations where such by-product material is used or possessed may include fees sufficient to cover the expenses incurred by the Department in conjunction with monitoring unlicensed properties contaminated with by-product material as defined in subsection (a-5)(2) of Section 4 and overseeing the decontamination of such unlicensed properties. The Agency may impose fees for termination of licenses including, but not limited to, licenses for refining uranium mill concentrates to uranium hexafluoride; licenses for possession and use of source material at ore buying stations, at ion exchange facilities and at facilities where ore is processed to extract metals other than uranium or thorium; and licenses authorizing the use or possession of by-product material as defined in subsection (a-5)(2) of Section 4. The Agency may also set license fees for licenses which authorize the distribution of devices, products, or sealed sources involved in the production, utilization, or containment of radiation. After a public hearing before the Agency, the fees and collection procedures shall be prescribed under rules and regulations for protection against radiation hazards promulgated under this Act.
