Gas Transportation Tariff (Tariff) as follows:
to modify provisions applicable to Diversions and Alternate Receipt Points (ARPs);
to eliminate the overrun feature of Storage Transportation Service (STS);
to eliminate provisions that establish requirements for the timing and duration of open
seasons for Short-Term Firm Transportation (STFT) service and Short-Term Short Notice
(ST-SN) service; and
to modify renewal provisions for Firm Mainline Services.2
