Oregon Revised Statutes Financial Institutions § 714.025

(1)(a) A banking institution may establish and operate one or more branches within or outside this state. Not later than 30 days before the board of directors of a banking institution establishes a branch, the banking institution shall file a notice with the Director of the Department of Consumer and Business Services that sets forth the name of the banking institution, the proposed location of the branch and the date on which the branch will begin operating. The director shall promptly advise the banking institution if the notice is incomplete or if the director requires additional information.

(b) The director may limit or restrict a banking institution's ability to establish an additional branch if the director determines that establishing an additional branch would adversely affect the banking institution's safety and soundness. A banking institution may appeal the director's decision in a contested case proceeding in accordance with ORS chapter 183.
