Enbridge Inc. subsidiary Texas Eastern Transmission LP has a planned timeline to resume natural gas flows through a line that was taken out of service following a fatal blast in central Kentucky. But the company cannot yet offer specific timing on startup for two other lines that were also shut in after the explosion.
Texas Eastern plans to restore some service to Line 25 some time between Aug. 24 and Aug. 26, once the operator completes construction and other activities on the portion of the 8,835-mile system, which delivers gas from the U.S. Gulf Coast to the mid-Atlantic and Northeast. The operator intends to restore about 800,000 Dth/d of capacity at that time, or roughly half of the typical capacity, the company said in an Aug. 15 update on its electronic bulletin board.
The Aug. 1 explosion on Line 15 near the Danville compressor station in Lincoln County, Ky., killed one woman. Texas Eastern also took the adjacent Lines 10 and 25 out of service as a safety precaution. The U.S. Pipeline and Hazardous Materials Safety Administration, or PHMSA, on Aug. 8 ordered Texas Eastern to keep the three lines out of operation and reduce pressure on other parts of the system until the company takes corrective actions.
All three lines are located between the Danville and Tompkinsville compressor stations in Kentucky. Texas Eastern said flows through Danville will remain at zero at least through the close of the day's gas nominations on Aug. 24.
Texas Eastern is working to replace parts of Lines 10 and 15, the company said. It has to get approval from PHMSA before restoring service on the lines, though.
"Prior to returning Line 10 and 25 to service, TE will address all of the site-specific concerns identified by PHMSA and will be undertaking rigorous inspections on Line 10 and 25 in compliance with the" corrective action order, Texas Eastern said.
The company expects construction and other activities on Line 10 to be completed by the end of August or first week of September. The operator warned that its work schedule could be impacted by weather and existing, unforeseen conditions on the lines.
Texas Eastern is also executing its plan to assess Line 15 between Kosciusko, Miss., and Uniontown, Pa., a roughly 775-mile-long stretch along which PHMSA ordered the company to reduce pressure by 20% until the agency approves higher pressure flows.
