How to Detariff
A telecommunications company can detariff by submitting a letter addressed to the commission. The letter should be filed by an authorized company representative into EFIS under the “revise current tariff” submission option and contain the following information:

  • A statement declaring the company's intent to detariff.
  • The effective date for detariffing.
  • The tariff or tariff pages to be withdrawn.
  • The website address containing rate information and service descriptions.

Detariffing Obligations
If the website changes, the company will need to submit a letter in EFIS using the “revise current tariff” submission option to notify the Commission of the revised website.
