Tariff Filings

In calculating the proposed effective date of a tariff, the date on which the tariff is filed with the Commission shall not be counted. The entire notice period must expire prior to the proposed effective date of the tariff. See also rule 1203(c).

When a utility files a proposed tariff, the Commission may suspend the proposed tariff’s effective date by ordering that a hearing be held. Pending hearing and decision, the proposed tariff shall not go into effect. The period of suspension shall not extend more than 120 days beyond the proposed effective date of the tariff, unless the Commission, by separate decision, extends the period of suspension for an additional period not to exceed 130 days.

In addition to the utility’s rates, classifications, rules, regulations, forms of contracts, terms, conditions, and service offerings, the following shall be included in the tariff:
