Miss. Code § 77-6-27
A municipality's or the authority's purchase of, contract for the acquisition of, or contract for any property, including any project or interest therein, or the construction of, or the operation and maintenance of, any project, owned or to be owned jointly by such municipality or the authority with any person, firm or corporation engaged in the production, transmission or distribution of gas, either within or without this state, other than with a municipality of this state or the authority created pursuant to this chapter, may be made or entered into without meeting the requirements of any law relating to acquisitions, purchases or contracts by competitive bids where the interest to be acquired by such municipality or the authority in such property or project is twenty-five percent (25%) or less.
If a municipality or the authority which finds and records on its minutes that acquisition of any project or any interest therein or any portion thereof, or any property or any interest therein or any portion thereof, which is authorized by this chapter is available or can be acquired or contracted for from or with a municipality or the authority or only a single source, person, firm or corporation, then such acquisition or contract may be made or entered into without meeting the requirements of any law relating to acquisitions, purchases or contracts by competitive bids. If, after advertising for competitive bids as to other proposed purchases, acquisitions or contracts, only one (1) bid is received, the municipality or the authority, as the case may be, may reject the bid and negotiate privately any purchase, contract or acquisition for a consideration not exceeding that proposed in the bid.
