DETROIT (AP) Federal regulators are scheduled to announce the likely cause of an underground pipeline rupture that spilled 800,000 gallons of oil into a Michigan river two years ago.
The National Transportation Safety Board is scheduled to vote Tuesday on a report submitted by staffers who investigated the spill near Marshall in southwestern Michigan.
The 30-inch pipeline sprang a leak July 25, 2010. Oil poured into the Kalamazoo River and a tributary creek. Enbridge Inc., of Calgary, Alberta, operates the line and has estimated its cleanup costs at $700 million. The Environmental Protection Agency is overseeing the cleanup, which continues.
The federal Pipeline and Hazardous Materials Safety Administration last week proposed a record $3.7 million civil penalty against Enbridge for what it said were numerous regulatory violations before and during the spill.
