Mississippi Code Title 57. Planning, Research and Development § 57-1-173

Whenever a supervisors district or a city, town or village in a supervisors district, or both, which adjoins a supervisors district in the same county, already having a certificate of convenience and necessity issued under the provisions of Sections 57-1-1 to 57-1-51, and which has already voted to engage in an enterprise authorized under the provisions of said sections, desires to join in the enterprise, the adjoining supervisors district or city, town or village, or both, wishing to so join may make application to the Mississippi Agricultural and Industrial Board for a certificate of convenience and necessity, the same as if such supervisors district or city, town or village, or both, had joined with the supervisors district already having a certificate of convenience and necessity in its original application. Such application shall show that the joining of the said supervisors district or city, town or village, or both, will benefit such municipality by the use of its natural resources or the employment of its labor, and that it has adequate property values and suitable financial conditions so that the total bonded indebtedness of the municipality shall not exceed twenty per cent (20%) of the total assessed valuation of all of the property in the municipality, and that the joining of such municipality in the operation of the enterprise by the supervisors district already holding a certificate of convenience and necessity shall result in the enlargement of the enterprise and that such enlargement of the enterprise shall benefit the petitioning municipality. The board may issue a certificate of convenience and necessity the same as if the petitioning municipality had joined in the original application. However, when bonds are issued jointly by a municipality and a county or a supervisors district of such county, then in such event, the limitation of twenty per cent (20%) of the assessed valuation of such municipality or county or supervisors district shall apply to each such taxing district even though such assessments include identical property.
