Notes

Questar rescheduled last Tuesday’s planned ball launching toThursday, June 3. Major allocations are expected.

PG&E Gas Transmission-Northwest now expects Unit 5-C toreturn to service for June 1 operations, raising Kingsgate capacityto 2,360 MMcf/d. The return of Unit 7-C is scheduled for June 10,with Kingsgate reaching 2,520 MMcf/d.

A direct lightning strike occurred Monday at Transwestern’sBisti Compressor Station (San Juan County, NM), prompting thepipeline to declare a force majeure. Transwestern expected thestation to be down about three days, saying San Juan Lateralcapacity would be reduced to 700,000 MMbtu/d through Thursday.

Citing continuing compressor repairs at Station 13, Northern BorderFriday extended a reduction of system throughput to 90% of summerdesign capacity (see Daily GPI, May 19)through Saturday and Sunday.

About 1 Bcf/d of NOVA capacity will be cut from May 31 to June9 as part of the system is inspected for stress corrosion crackingwhile tie-ins and other maintenance are performed. NOVA will take100 miles of 36-inch line between the Miekle River and Knightcompressor stations in northwest Alberta out of service during thattime. NOVA normally moves a total of about 11.8 Bcf/d, a spokesmansaid.

NOVA estimated that repairs to a flange assembly leak on its NorthLateral (see Daily GPI, May 17), whichstarted Wednesday, would take 24-36 hours to complete. Some receiptsupstream of Dusty Lake Compressor Station are being curtailed by thework.

Trunkline postponed a three-day outage of Valve Section 32between the Cypress and Kountze Stations in East Texas until June.It will require shutting in all receipts upstream of the sectionunless they entail equal deliveries upstream.

Northwest began running a 96-hour test on the Snohomish (WA)Compressor Station’s Unit No. 1 Friday. The test, along with warmerweather and reduced weekend damand, did not allow Northwest toreceive the full 1,097,000 dekatherms of total supply at theSumas/Sipi throughput point. The pipeline capped Sumas/Sipi volumesat 1,000,000 dekatherms Sunday and raised that to 1,050,000dekatherms for Monday’s gas day. No constraint is scheduled todayas the work was expected to end Monday evening.

NOVA said a leak discovered in a flange assembly early Thursdayon its North Lateral in eastern Alberta is curtailing up to 500MMcf/d of upstream production. The line usually flows 1.6-1.7Bcf/d, a spokesman said. He estimated the leak will require 24-48hours of repair time, but no schedule has been set.
