For taxable years beginning after December 31, 1988, the governing body of a municipality may grant additional exemptions of property under this section during a period not exceeding ten years from the date of commencement of project operations in the structure if the structure is owned by the United States, the state, or a political subdivision of the state and leased to the project operator.
