ONEOK Minnesota natgas line remains shut after explosion-sheriff
May 27 (Reuters) - A natural gas pipeline in northwestern Minnesota owned by ONEOK Inc's Viking Gas Transmission unit remained shut early Tuesday after exploding early Monday, the 911 coordinator for the Marshall County sheriff's department said.
Jim Duckstad, the 911 coordinator, told Reuters two towns remained without gas Tuesday morning - Warren with about 1,500 residents and Argyle with about 500 residents.
He said Viking told the towns it hoped to restore gas service by Wednesday.
Officials at ONEOK were not immediately available for comment.
Viking Gas Transmission transports gas from Canada from TransCanada Corp's pipeline near Emerson, Manitoba, to serve local natural gas distribution companies in Minnesota, North Dakota and Wisconsin. It terminates at a connection with TransCanada's ANR Pipeline near Marshfield, Wisconsin, according to the ONEOK website.
Viking has a capacity of 0.5 billion cubic feet per day, according to a U.S. Federal Energy Regulatory Commission filing in 2012.
It connects with four major pipeline systems - TransCanada, MidAmerican Energy Holdings' Northern Natural Gas Co and TransCanada's Great Lakes Gas Transmission LP and ANR units.
MidAmerican is a unit of Berkshire Hathaway Inc.
Duckstad said the pipe that exploded was a 24-inch pipe. He said the company was still investigating the cause. Continued...
