Enbridge Inc. has been replacing and repairing parts of line "6B" as part of its maintenance and rehabilitation program. The pipeline was built in 1969.
Now company officials want to replace 200 miles of the oil pipeline in Michigan.
The "6B" pipeline broke open near Marshall, Michigan in 2010 and spilled more that 840,000 gallons of thick tar sands oil into Talmadge Creek and the Kalamazoo River. There are still pockets of thick oil at the bottom of the Kalamazoo River.
The 6B pipeline has been operating at reduced capacity since the spill.
Crystal Garcia of the Times Herald of Port Huron reported on Enbridge's plan today.
She writes the existing pipeline is pumping around "243,000 barrels of oil a day with the pressure restrictions." A company spokesman, Joe Martucci, said the new pipeline would produce about 500,000 barrels of oil a day.
If plans are approved, Garcia reports the existing pipeline will be taken offline and remain in place, and the new pipeline will be built about 25 feet from the existing line.
Replacing the pipeline will be done in two phases, Martucci said. Part of the first phase — which includes two five-mile segments east of pumping stations near Griffith and LaPorte, Ind. and three five-mile segments east of Niles, Mendon and Marshall — already has been approved. The other part of the first phase — a 50-mile segment between Stockbridge and Ortonville — is near approval. Work on the first phase will be done this year, Martucci said... Phase two includes 210 miles of pipeline from Griffith, Ind. to Marysville that was not replaced during phase one. A preliminary hearing for the phase two proposal will be at 9 a.m. June 6 in Lansing
The Times Herald reports if the plans are approved, most of the construction work would be done in 2013.
