Mo. Rev. Stat. § 68.055

68.055. Letting of contracts, manner, amounts. — 1. Every port authority shall let contracts for all work to be done and for equipment, supplies or materials to be purchased. Excepting as otherwise provided herein, such contracts shall be given to the lowest responsible bidder therefor, upon not less than twenty days' notice of the letting, given by publication in a newspaper of general circulation in the city or county creating the port authority; and in the discretion of the commissioners, in one or more newspapers of general circulation among contractors. The port authority shall have the power and authority to reject any and all bids and to readvertise the work or proposed purchase.

2. Notwithstanding the provisions of subsection 1 of this section, every port authority may let contracts in a manner consistent with the procedures set forth in 24 CFR Section 85.36, "Uniform Administrative Requirements for Grants and Cooperative Agreements to State and Local Government", as may be revised from time to time, regardless of the source of funds for the procurement, except that if a funding source mandates specific procedures for letting contracts as a condition to receipt of funds which are inconsistent with the procedures authorized in this section for letting contracts, a port authority may use such procedures required by the funding source.

3. Notwithstanding the provisions of subsection 2 of this section, the dollar limit of procurements which may, pursuant to subsection 2 of this section, be accomplished using "small purchase procedures", shall, for the purposes of procurements to be paid for with funds other than federal funds, adjust annually based on the rate of inflation according to the Consumer Price Index, commencing in 1995.
