ORS § 224.410
If any municipality fails to meet, when due, any obligation sold to the state under authority of ORS 224.310 to 224.420, the State Treasurer, with the approval of the circuit court of the county in which the major portion of the assessed valuation of the municipality is located, may appoint a receiver to operate the system. The receiver shall act in the capacity of receiver so long as the circuit court deems receivership necessary to protect the interests of the state and of the municipality. In order to insure prompt payment of interest or principal of bonds acquired by the State Treasurer pursuant to ORS 224.380, the State Treasurer may withhold and apply to the payment of such obligations, any moneys which may accrue to the municipality from state sources. Moneys so withheld shall be repaid to the municipality when the funds with which to meet the obligations for the payment of which funds were withheld are paid by the municipality to the state. The right to withhold said moneys for the purpose provided in this section shall exist only so long as any of the sewage bonds of the municipality are owned by the state.
