(a) An in-state natural gas pipeline carrier shall file with the commission a complete recourse tariff containing rates, rules, regulations, terms, and conditions pertaining to service provided under the certificate and copies of all contracts with shippers that in any way affect or relate to the carrier's rates, tariffs, charges, classifications, rules, regulations, terms, and conditions to service provided under the certificate.
(b) The terms and conditions under which an in-state natural gas pipeline carrier offers its services and facilities to the public shall be governed strictly by the provisions of its currently effective recourse tariff as supplemented and modified by contracts that have been approved by the commission. A legally filed and effective recourse tariff rate, charge, rule, regulation, or condition of service may not be changed except as provided in this chapter. The in-state natural gas pipeline carrier shall maintain copies of its recourse tariff on file at its principal business office and at places designated by the commission and make the copies available to and subject to inspection by the general public on demand.
(c) A change in a recourse tariff rate, charge, rule, regulation, or condition of service is not effective until filed under (a) of this section. If more than one recourse tariff rate or charge may reasonably be applied for billing purposes, the recourse tariff rate or charge most advantageous to the shipper shall be used.
(d) The commission may reject the filing of all or part of a recourse tariff that is not consistent with this chapter. A recourse tariff rate or provision so rejected is void.
(e) Initial and revised recourse tariffs shall be filed in the manner provided in AS 42.08.350.
