Section 31.01.01.134 - TARIFF ADVICES01.Tariff Advices Authorized. Public utilities may file tariffs adding new or modifying existing services, providing for new or modified rules, or otherwise making minor changes to existing schedules by tariff advice. The tariff advice must include a transmittal letter from the utility listing all tariff pages changed or added by the tariff advice and briefly stating the reason for the tariff advice. If existing tariffs are changed, the advice must contain two (2) copies of each changed page: one (1) showing all the changes with appropriate symbols for deletions, additions, etc., and one (1) showing the pages after the changes as they will appear in the proposed new tariffs.02.Filing of Tariff Advice. No tariff advice can be effective unless notice is given to the Commission and the public under Sections 61-307 and 61-622, Idaho Code. Tariff advices typically do not take effect on less than thirty (30) day notice. If the tariff advice proposes an effective date fewer than thirty (30) days after it is filed, the proposed effective date is delayed until thirty (30) days after the tariff advice is filed by operation of Sections 61-307 and 61-622, Idaho Code, unless the Commission finds good cause to approve an earlier effective date. Absent an order approving or suspending the tariff advice, the tariff advice takes effect thirty (30) days after filing or on the proposed effective date, whichever is later. If no effective date is proposed for the tariff advice, the tariff advice does not take effect until approved by order or minute entry. If a tariff advice is suspended, the Commission will open a formal proceeding and treat the tariff advice as an application.03.Ex Parte Action. Ordinarily, the Commission acts upon tariff advices with the assistance of a written ex parte recommendation of the Commission Staff. The Commission acts upon tariff advices at its open meetings. If Staff believes the tariff advice proposes non-minor changes, then Staff should recommend the Commission process the tariff advice as an application, suspending the proposed effective date as needed.Idaho Admin.
