Oregon Revised Statutes Utility Regulation § 759.210

(1) The Public Utility Commission shall provide for a comprehensive classification of service for each telecommunications utility. The classification may take into account the quantity used, the time when used, the purpose for which used, the existence of price competition or a service alternative, the services being provided, the conditions of service and any other reasonable consideration. Based on these considerations the commission may authorize classifications or schedules of rates applicable to individual customers or groups of customers. Each telecommunications utility is required to conform its schedules of rates to such classification. If the commission determines that a tariff filing under ORS 759.175 results in a rate classification primarily related to price competition or a service alternative, the commission, at a minimum, shall consider the following:

(2) The commission may prescribe any changes in the form in which the schedules are issued by any telecommunications utility as the commission finds to be expedient. The commission shall adopt rules that allow any person who requests notice of tariff filings described under subsection (1) of this section to receive such notice.
