Oregon Revised Statutes Utility Regulation § 758.435

(1) Any person providing a utility service in a territory that is not served by another person providing a similar utility service may make application to the Public Utility Commission for an order allocating such territory to it. The application may include any adjacent area that it is more economical and feasible to serve by an extension of the applicant's existing facilities than by an extension of the facilities of another person.

(2) The commission shall within 30 days after the filing of such application give notice of the filing. If the commission chooses, or if a customer requests a hearing on the matter within 30 days of the notice, the commission shall hold a hearing by telephone or in person. The commission shall give notice of the hearing within 30 days of the request which notice shall set the date and place of hearing. The hearing shall be held at a place within or conveniently accessible to the territory covered by the application. Notice of the filing shall be by publication in a newspaper or newspapers of general circulation in the territory covered by the application and shall be published at least once weekly for two successive weeks. Written notice of the filing shall be given to providers of similar utility service in adjacent territory.

(3) Territory within the limits of a city, as fixed on May 31, 1961, shall not be deemed to be served exclusively by any person, if such city is, on such date, served by more than one person having necessary municipal or franchise authority to serve within the entire city.
