Columbia Gas is designating Wednesday as a Critical Day in Market Areas 20, 21, 22, 23, 24, 25, 28, 29, 30, 31, 33 and 34. “Based on forecasted markets, available facilities and capacity utilization, transporter [Columbia] projects that all available capacity to the aforementioned Market Areas will be required to meet firm service obligations, leaving…zero nonfirm capacity,” the pipeline said. Shippers with primary firm rights or secondary priority rights in the affected Market Areas will not be impacted.

Effective Wednesday until further notice, Northwest is issuing a Recall Advisory and invoking OFO provisions. Primary volumes of about 631,000 Dth/d scheduled northbound through the Plymouth South Constraint Point exceed the design capacity of 550,000 Dth/d and Northwest’s physical capacity, which currently averages about 590,000 Dth/d, the pipeline said, and it is no longer able to mitigate these high volumes using its limited storage flexibility. See the bulletin board for details of requirements under the Recall Advisory and the Notice of OFO relating to the Plymouth South Constraint Point. Northwest also lifted Tuesday a Declared Entitlement for Overruns for all Receiving Parties south of Plymouth Compressor Station but said an overrun entitlement for Receiving Parties north of Plymouth Compressor Station will remain at 8% (Stage II) until further notice.

Gulf South began unscheduled maintenance Monday on Unit #2 at the Clarence (LA) Compressor Station. The work was expected to continue for about 48 hours and could reduce capacity through the station by as much as 100,000 Dth/d, Gulf South said.

TGT reported the completion of unscheduled maintenance at the Youngsville Compressor Station in South Louisiana (see Daily GPI, Nov. 27) and said it would restore capacity in the Youngsville East segment to 563,000 MMBtu/d at 5 p.m. CDT Tuesday.

Wyoming Interstate Co. plans to put the first 51 miles of the Kanda Lateral in service Wednesday, an official of parent company El Paso Corp. said.

The facilities will increase WIC’s capacity out of the Uintah Basin in Utah by approximately 406,000 Dth/d.
