  CHAPTER I--FEDERAL ENERGY REGULATORY COMMISSION, DEPARTMENT OF ENERGY
 
PART 154--RATE SCHEDULES AND TARIFFS--Table of Contents
 
              Subpart A--General Provisions and Conditions
 
Sec. 154.3  Effective tariff.

    (a) The effective tariff of a natural gas company is the tariff 
filed pursuant to the requirements of this part, and permitted by the 
Commission to become effective. A natural gas company must not directly 
or indirectly, demand, charge, or collect any rate or charge for, or in 
connection with, the transportation or sale of natural gas subject to 
the jurisdiction of the Commission, or impose any classifications, 
practices, rules, or regulations, different from those prescribed in its 
effective tariff and executed service agreements on file with the 
Commission, unless otherwise specifically permitted by order of the 
Commission.
    (b) No tariff provision may purport to change an effective rate or 
charge except in the manner provided in section 4 of the Natural Gas 
Act, and the regulations in this part. The tariff may not provide for 
any rate or charge to be automatically changed by an index or other 
periodic adjustment, without filing for a rate change pursuant to these 
regulations.
