Notwithstanding the provisions of §26.53 of this chapter (relating to Surplus Revenue) to the contrary, the commission may, as a condition to the transfer, require that expenditures of surplus revenue, if any, derived from a transferred ferry be made to implement projects included in the metropolitan transportation plan or the department's unified transportation program. Within the project operating agreement described under §26.54 of this chapter (relating to Project Operating Agreement), the commission and the RMA shall, prior to transfer, mutually agree to the amount of expenditures subject to this section and projects to be funded under this section. These provisions may be revised at any time upon agreement of both parties.
