No person may dispose of, store, or accept any spent nuclear fuel which was used in any power generating facility located outside this State, or transport into this State for disposal or storage any spent nuclear fuel which was used in any power generating facility located outside this State, unless the state of origin of such spent nuclear fuel has a facility, which is not part of a power generating facility, for the disposal or storage of spent nuclear fuel substantially like that of this State and has entered into a reciprocity agreement with this State. The determination as to whether the state of origin has a disposal or storage facility for spent nuclear fuel substantially like that of this State is to be made by the Director of the Illinois Emergency Management Agency and all reciprocity agreements must be approved by a majority of the members of both Houses of the General Assembly and approved and signed by the Governor.
