Minn. Stat. § 469.061
A port authority may decide by resolution to issue its revenue bonds either at one time or in series from time to time. The revenue bonds may be issued to provide money to pay to acquire land needed to operate the authority, to purchase, construct, install, or furnish capital equipment to operate a port terminal, transportation, or industrial facility of any kind in its port district, or to pay to extend, enlarge, or improve a project under its control. The issued bonds may include the amount the authority considers necessary to establish an initial reserve to pay principal and interest on the bonds. The port authority shall state in a resolution how the bonds and their attached interest coupons are to be executed.
The bonds of each series issued by the port authority under this section shall bear interest at a rate or rates, shall mature at the time or times within 30 years from the date of issuance, and shall be in such form, whether payable to bearer, registrable as to principal, or fully registrable, as determined by the port authority. Section 469.060, subdivision 7, shall apply to all bonds issued under this section, and the bonds and their coupons, when payable to bearer, shall be negotiable instruments.
The sale of revenue bonds issued by the port authority shall be at public or private sale. The bonds may be sold in the manner and for the price that the port authority determines to be for the best interest of the port authority. The bonds may be made callable, and if so issued may be refunded.
The port authority may by resolution make an agreement or covenant with the bondholders or their trustee if it determines that the agreement or covenant is needed or desirable to carry out the powers given to the authority under this section and to assure that the revenue bonds are marketable and promptly paid.
In issuing bonds under sections 469.049, 469.050, and 469.058 to 469.068, the port authority may secure the payment of the principal and interest on the bonds by a pledge of and lien on port authority revenue. The revenue must come from the facility to be acquired, constructed, or improved with the bond proceeds or from other facilities named in the bond-authorizing resolutions. The authority also may secure the payment with its promise to impose, maintain, and collect enough rentals, rates, and charges, for the use and occupancy of the facilities and for services furnished in connection with the use and occupancy, to pay its current expenses to operate and maintain the named facilities, and to produce and deposit sufficient net revenue in a special fund to meet the interest and principal requirements of the bonds, and to collect and keep any more money required by the resolutions. The authority shall decide what constitutes "current" expense under this subdivision based on what is normal and reasonable under generally accepted accounting principles. Revenues pledged by the port authority must not be used or pledged for any other port authority purpose or to pay any other bonds issued under this section or under section 469.060, unless the other use or pledge is specifically authorized in the bond-authorizing resolutions.
Revenue bonds issued under this section are not a debt of the port authority's city nor a pledge of that city's full faith and credit. The bonds are payable only from project revenue as described in this section. A revenue bond must contain on its face a statement to the effect that the port authority and its city do not have to pay the bond or the interest on it except from revenue and that the faith, credit, and taxing power of the city are not pledged to pay the principal of or the interest on the bond.
Sections 469.153, subdivision 2, paragraph (e), and 469.154, subdivisions 3, 4, and 5, do not apply to revenue bonds issued under this section and sections 469.152 to 469.165 if the interest on the revenue bonds is subject to both state and federal income tax or if the revenue bond proceeds are not loaned by the port authority to a private person.
