(a) If the commission and an agency agree to the installation and operation of an additional vending facility or vending machine on property that already has a commission-sponsored vending facility, no additional permit or license is required. However, the installation of a competing vending facility consisting of vending machines or other coin-operated devices must be authorized by the commission. The commission’s authorization must be made with a view toward providing the greatest economic benefits for blind persons consonant with supplying the additional services required at the building.
(b) State agencies shall cooperate and negotiate in good faith to accomplish the purposes of this chapter.

(c) Individuals with disabilities who operate vending facilities on state property are entitled to receive all commissions from vending machines installed on the same property. If two or more vending facilities are operated by individuals with disabilities in a building in which vending machines are installed, the commission shall divide the commissions from the vending machines among the operators with disabilities in a manner that will achieve equity and equality in the incomes of those operators. If the commission has decided not to locate a vending facility in a building, the agency to whom a general permit has been issued shall determine the assignment of the commissions from vending machines installed in the building.
