(1) In the case of a federally declared disaster, the state cost-share under this article shall be equal to twenty-five percent (25%) of the actual cost of implementing the Other Needs Assistance Program, and shall be made only on the condition that the federal government provides the remaining seventy-five percent (75%) of the ONA grant. In the event of a Governor's state of emergency declaration, the state grant under this article shall be equal to an amount established by the Director of the Mississippi Emergency Management Agency.
