ORS § 468.269
The proceedings authorizing the issuance of bonds may provide for the appointment of one or more trustees for the protection of the holders of the bonds, whether or not a mortgage is entered into as security for such bonds. A bank with trust powers or a trust company within or without the State of Oregon may be appointed as trustee and shall be located in the United States, and shall have the immunities, powers and duties provided in said proceedings, and may, to the extent permitted by such proceedings, hold and invest funds deposited with it in direct obligations of the United States, obligations guaranteed by the United States or certificates of deposit of a bank, including the trustee, which are continuously secured by such obligations of or guaranteed by the United States. Any bank acting as such trustee may, to the extent permitted by such proceedings, buy bonds issued under ORS 468.263 to 468.272 to the same extent as if it were not such trustee. The proceedings authorizing the bonds may provide that some or all of the proceeds of the sale of the bonds, the revenues of any facilities, the proceeds of the sale of any part of a facility, or of any insurance policy or of any condemnation award shall be deposited with the trustee and applied as provided in the proceedings.
