Southern Natural Gas will implement an OFO Type 6 for short imbalances effective Friday until further notice. No penalty will apply to short imbalances up to 2% or 200 Dth, whichever is greater; tiered penalties were set for larger imbalances. Saying forecasts indicated “significantly colder weather” in its service area from Wednesday evening through Saturday, Southern told customers that “based on current supplies and anticipated demand,” it expected its storage withdrawal capability to be exceeded “by approximately 540 MMcf” for Thursday’s gas day. It also said that based on supply patterns from recent high-throughput days, it will be evaluating and potentially allocating receipt points west of Enterprise Compressor Station, which is on its south mainline in southern Mississippi. Fifteen receipt groups (see the bulletin board for a list) could be impacted, Southern said. It combined them into “newly defined parent group” 181-West of Enterprise Supply Group.

Pacific Gas & Electric did not extend a systemwide low-inventory OFO beyond Wednesday.

After ending two System Overrun Limitations (SOL) Wednesday, Northern Natural Gas said it will reinstate the SOL for the New Market, MN, #1 Town Border Station Thursday. The other SOL, which had applied to all market-area zones, is being renewed Thursday only for Zone E/F “due to below-zero forecasted minimum temperatures,” Northern said.

Tuesday’s ice storms in Arkansas and Missouri have caused the loss of commercial power to some Texas Eastern compressor stations on its 24-inch diameter mainline, the pipeline said Wednesday. The Fagus and Egypt stations in Arkansas “are currently not fully operational,” Texas Eastern said, adding that it was evaluating the capacity impact and its ability to meet scheduled quantities through Fagus for Thursday’s gas day and beyond.

TGT also was having problems with the severe weather, saying it required the closing Wednesday of the pipeline’s headquarters office in Owensboro, KY. TGT said it was operating with its emergency staff and apologized “for any slow response times” that customers might experience.

Transco said Tuesday afternoon it had experienced a mechanical failure on a gas turbine-driven compressor at Station 167 in South Hill, VA. The station is on Transco’s South Virginia Lateral. The pipeline said the exact duration of the unit’s outage was unknown “but could last several weeks.” No impact to primary firm capacity is anticipated, Transco said, but downstream delivery locations may experience lower-than-normal pipeline pressure during times of high demand on the lateral.

Southern California Gas said repairs of a compressor unit at its Honor Rancho storage facility are now expected to continue through next Wednesday. The work, which is causing a 50 MMcf/d loss of injection capacity, previously was expected to last only through Friday (see Daily GPI, Jan. 26).

Columbia Gulf said it expects to transfer ownership of the West Cameron 426 Lateral to Petroleum Fuels LLC effective Sunday. After the transfer Columbia Gulf will no longer provide transportation service at the West Cameron 426A, 426C and 414 receipt point meters.
