Southern Natural Gas canceled Monday the Type 6 OFO for short imbalances that had been issued last Thursday. But the pipeline said Tuesday a new OFO Type 6 for short imbalances will go into effect at the start of Thursday’s gas day (Jan. 24). An OFO Type 3 Level 2 affecting the Savannah Line and Cypress Line delivery groups until further notice will be implemented at the same time, Southern said. In addition, it will begin allocating/limiting interruptible capacity in the Birmingham, Gadsden, Chattanooga, East Tennessee, Atlanta North and Tallapoosa groups Thursday until further notice.

Northwest, which had told shippers it would reevaluate the need for a Stage II (8% imbalance tolerance) Overrun Entitlement for all receiving parties north of Kemmerer (WY) Compressor Station following the holiday weekend, said Tuesday it was extending the entitlement until further notice due to cold temperatures being forecasted to continue through this week in the Pacific Northwest. The entitlement was implemented last Friday.

El Paso ended Sunday the Strained Operating Condition (SOC) for a Draft condition that had been declared Friday. However, as of Tuesday morning the pipeline said it had set the probability of declaring a new SOC or a Critical Operating Condition to high, this time due to high linepack.

Columbia Gulf again began limiting nominations at its Sea Robin meter at up to 100,000 Dth/d Tuesday until further notice after Sea Robin Pipeline announced that the Hess Corp.-operated Sea Robin Gas Processing Plant was shut in Sunday for what could be a minimum of three days. The plant will continue to dehydrate, Sea Robin Pipeline said, but Plant Thermal Reduction nominations must be reduced to zero during the current outage. A similar outage and Columbia Gulf restriction last week had ended Saturday (see Daily GPI, Jan. 22).

ANR lifted Tuesday the restriction on Interruptible Park and Lend Service that had been implemented Friday.

Westcoast declared a 12.4% firm hydrogen sulfide constraint Sunday at Fort Nelson Gas Plant due to problems with the #10 sulfur train. The pipeline expected full operations to resume at Fort Nelson Wednesday morning.

Gulf South began unscheduled maintenance on Montpelier Compressor Station’s Unit #7 Tuesday that is expected to continue for about five days and could cut station capacity by as much as 50,000 Dth/d.
