El Paso Energy Intrastate (formerly known as Channel) experienced a rupture of its 30-inch line Monday evening near Baytown, TX, east of Houston. There was no fire, but a voluntary evacuation of the area was conducted, a spokeswoman said. One injury was reported as a result of the evacuation, and as of midday Tuesday everyone had returned home except for two families whose homes were damaged, she said. No service interruptions are expected as all demands are being met through gas re-routing or fuel switching, the spokeswoman said. The line probably will be returned to service by the end of the week. It is owned 50-50 by El Paso Energy and Enron Corp. and is operated by El Paso Field Services.
Florida Gas Transmission kept an Overage Alert Day notice in place Tuesday until further notice at 10% tolerance for negative daily imbalances. However, it said due to the demand created by near-freezing temperatures in its market area, "there is also a strong possibility" that the tolerance may be lowered today.
A System Overrun Limitation notice for all market area zones by Northern Natural Gas remains in effect through at least today.
Pacific Gas & Electric did not extend a customer-specific OFO beyond Tuesday.
After saying Monday it expected OFOs and allocations implemented over the weekend to last through Thursday (see Daily GPI, Dec. 5), Sonat canceled at the start of Tuesday's gas day an OFO Type 22 for its South Georgia system and an OFO Type 3 for seven mainline groups.
ANR said Tuesday that based on current weather forecasts for Wisconsin, it has become increasingly important that ANR maintain sufficient receipt volumes at its Marshfield, WI, interconnect with Viking. Nominations there as of the 9:00 intraday cycle Monday were about 208,000 Dth/d, ANR said. Any significant reduction from those levels may require further action such as an OFO, it said.
Citing colder weather forecasts and their impact on system demand, starting today Texas Eastern anticipates total restriction of secondary volumes flowing through Lambertville (NJ) Station. Shippers without FT rights at that node will be cut. Also, the pipeline said Tuesday that current throughputs at Berne (OH) Station "are less than scheduled volumes would indicate or operational conditions require." Thus, to better manage supply arriving into market zones 2 and 3, Texas Eastern is suspending all Operational Balancing Agreements with non-interstate pipes upstream of Berne. However, it warned that all supply meters risk having their markets cut if physical receipts do not match scheduled nominations.
El Paso Natural Gas reported Monday experiencing an emergency shutdown of the GE turbine at its Waha Plant. The plant is expected to resume normal operations Thursday. Meanwhile, El Paso Field Services has cut wellhead nominations on six area gathering systems to zero through today.
Until further notice, NGPL said Tuesday, it is unable to schedule increases to interruptible storage withdrawals systemwide between WQ and MDQ for DSS, FSS and NSS customers. Best efforts service and withdrawals over MDQ are not available. Also, starting today the pipeline will schedule firm withdrawals up to WQ only for DSS, FSS and NSS customers.
