Whenever feasible, one or more vending facilities shall be established on all state property to the extent that any such facility would not adversely affect the interests of the state. Any limitation on the placement or operation of a vending facility based on a finding that such placement or operation would adversely affect the interests of the state shall be fully justified in writing to the licensing agent. The licensing agent may construct and install or permit the construction and installation of a vending facility on any property owned or occupied by the state and shall notify the department, agency or institution charged with the operation of the property of its intentions. If the state department, agency or institution charged with the operation of the property disapproves of the construction or installations, it may notify the licensing agent in writing of its objections within ten days of notification by the licensing agent of the licensing agent’s intention. The licensing agent and the state department, agency or institution charged with the operation shall consult and attempt to reach a mutually satisfactory agreement as to the proposed changes in the property. If agreement is not reached within thirty days of the time of receipt of the notification of disapproval, the licensing agent may apply to the board of public buildings for approval. The board of public buildings shall grant or refuse to grant approval within thirty days. If the board of public buildings takes no action within the specified time, it shall be deemed to have approved the proposed changes. Whenever approval for the proposed construction or installation is granted by either the state department, agency or institution charged with operation of the property or the board of public buildings, the licensing agent may proceed with construction or installation. In the case of leased space, cost shall be shared by agencies occupying such space as determined by the licensing agent.
