Indiana Code Title 8. Utilities and Transportation § 8-10-5-12

Sec. 12. The port authority shall foster and encourage the participation of private enterprise in the development of the port facilities to the fullest extent it deems practicable in the interest of limiting the necessity of construction and operation of such facilities by the port authority.  In this respect the port authority may upon its own motion or upon the written request of any other party advertise and solicit for the construction, operation and/or maintenance of any facility included in the development plan in accordance to plans, specifications and regulations therefor prepared by the board of directors.

It is further provided that in the event the board of directors deems it advisable and practicable, said board may cause certain facilities included in the development plan to be installed by private enterprise and leased back to the port authority on an instalment contract or option to purchase.  The exercise of any power granted to the port authority under the provisions of this section shall be consummated and regulated in accordance with detailed provisions set out and enacted into proper legislation by the governing body or governing bodies creating such port authority.
