(a) The county commission shall pay from the county treasury, at the regular legal rate, the cost of the advertising of notice and substance of all local bills which may be introduced in the Legislature by any member of the Legislature from the county, if the notice is signed by the member, whether the bill is passed by the Legislature or not. If the bill is for the benefit of or in reference to subjects or matters exclusively relating to one or more municipalities in the county, the municipality or municipalities shall reimburse the county for the cost of the advertising. If two or more municipalities are liable to reimburse the county for the cost of advertising the same bill, each municipality shall pay to the county an amount which bears the same ratio to the total cost of advertising as such municipality's population bears to the total population of all the municipalities affected by the bill.
(b) After August 1, 1998, except in the case of a bill for the benefit of or on subjects or matters exclusively relating to one or more municipalities in the county, if a proposed local law raising revenue for a public or private local entity other than the county commission becomes law, the public or private local entity receiving the proceeds of the revenue raising measure shall reimburse the county commission for the cost of advertising the local law from the first revenues generated by the local law. If the proposed local law would raise revenue for two or more local public or private entities, including the county commission or a municipality, each entity shall pay from the first revenues generated by the law, a pro rata share of the cost of advertising based upon the proposed percentage of generated revenue to each entity under the local law.
