For the purposes of paying the cost of acquiring any lands or making any improvements thereon or the acquisition of any equipment for the purposes hereinbefore authorized, the board of county commissioners may use moneys from the general fund, from any refuse disposal fund created under the provisions of this act, from the sale of property as hereinafter provided, or may issue general obligation bonds or bonds payable from revenue derived from service charges made for the use of the facility of the county as hereinafter provided. Before any bonds shall be issued by any county under the provisions of this act, the board of county commissioners shall publish a notice once each week for two (2) consecutive weeks in the official county newspaper. Such notice shall state the purpose, whether for acquisition or improvement of a site, or both, describing any such improvement, or the acquisition of equipment, for which such bonds are to be issued and the amount of the bonds to be issued therefor and whether they are to be general obligation bonds or revenue or part general obligation bonds and part revenue bonds. If within thirty (30) days after the last publication of said notice there shall be filed in the office of the county clerk, not later than five (5) o’clock p.m. on the last day, a protest signed by electors of the county equal in number to not less than ten percent (10%) of the electors who voted in such county for the secretary of state at the last preceding general election, an election shall be called and held within ninety (90) days after the last publication of the notice or at the next general election if held within that time. The signatures to such protest need not all be appended to one (1) paper but one (1) of the signers of each such paper shall make oath before an officer competent to administer oaths that each signature to the paper is the genuine signature of the person whose name it purports to be. Such election shall be called and held in the manner provided by the general bond law for bond elections. If no protest or no sufficient protest is filed or if an election is held and the proposition carries by a majority of those voting thereon at the election, the board of county commissioners may provide for the issuance of such bonds for the purposes and in the amount or amounts (if part are general obligation and part revenue bonds) provided in the published notice in the manner provided by law. Such bonds are hereby exempt from and shall not be included in computing the total bonded indebtedness of any county as prescribed by article 3 of chapter 10 of the Kansas Statutes Annotated.
