Update 2:03 p.m.

Officials say the gasoline leak has been stopped. Still no word on how much fuel leaked from the storage tank.

From the Associated Press:

Officials say they've stopped a gasoline leak in Michigan and confirmed the source as a storage tank in the area.

Ingham County emergency officials said in a statement Monday that the tank and a related filling system in White Oak Township, about 55 miles west of Detroit, are owned by Marathon Pipe Line LLC.

A message seeking comment was left Monday by The Associated Press at Marathon's offices.

Wolverine Pipe Line Co., which also owns some tanks at the same storage site, has been working with the county on response to the leak since it was reported Wednesday.

The county says Marathon will take over work dealing with the leak from Wolverine. The amount of the spill remains unknown. There's no evidence of health hazards in the area.

9:07 a.m.

Authorities say they've found the source of the gasoline leak in Ingham County.

From the Associated Press:

Michigan authorities say they've traced a gasoline leak to the area of a storage tank holding 14,700 barrels of fuel. Ingham County Emergency officials said in a statement Sunday that they've found higher levels of spilled gasoline as their monitoring equipment approaches the Wolverine Pipeline Co. facility.

The large gasoline storage tank site is in White Oak Township, about 55 miles west of Detroit.

Some of the gas flowed about a mile down an open drain by the time a farmer reported the leak Wednesday.

The county says the suspected source of the leak is a tank that can hold up to 180,000 barrels of fuel. It says that while the amount of the spill remains unknown, it's nowhere near the capacity of the tank, which was mostly empty when the leak started.

Michigan Radio's Kyle Norris reported yesterday that officials from the Wolverine Pipeline Company were searching for the gasoline leak.

The company that owns a pipeline that's leaking gasoline in Michigan is still searching for the source of the leak.   

Ingham County Emergency officials said in a statement Saturday that Wolverine Pipeline Company crews hope to find the leak within the next 24 hours and repair it. The Portage, Michigan-based company has contained the leak near a farm and a large gasoline storage tank facility about 55 miles west of Detroit.   

Some of the gas flowed about a mile down an open drain by the time the leak was reported Wednesday by a farmer. 

Crews continued digging temporary ditches Saturday near the storage tank to keep it out of the drain.   

Wolverine Pipeline says tests on wells in the area show that they pose no threat to human health.

The Anglers of the Au Sable has issued a new report that details the group’s concerns over oil and gas pipelines in northern Michigan. They’re especially worried about protecting the Au Sable and Manistee Rivers.

John Bebow is with the Anglers group. He says they started investigating pipelines after the major oil spill last summer in the Kalamazoo River. A pipeline owned by Enbridge Energy Partners broke... and spilled more than 800,000 gallons into the river.

“And we quickly determined an even bigger pipeline owned by the same company flows under the Au Sable and its tributaries numerous times.”

That pipeline is called Line 5. It’s the largest oil pipeline in the Midwest... and it goes through the very heart of the Au Sable watershed. The report notes that Line 5 carries as much as 22 million gallons of crude oil and natural gas liquids beneath the Au Sable River every day.

John Bebow calls the Au Sable a world class trout stream. He says if there were an oil spill... it would be devastating.

“The Au Sable River is a major magnet for tourism and recreation. It is a river life up there.”

More than six months after 800,000 gallons of oil spilled into the Kalamazoo River, cleanup efforts continue, the Associated Press reports.

The oil leaked from a pipeline near Marshall, MI. The pipeline, owned by Enbridge Energy, runs from Griffith, Indiana to Sarnia, Ontario.

The AP reports:

The U.S. Environmental Protection Agency said in November that much of the cleanup has been finished but some operation and maintenance "will continue for the foreseeable future.

Congress held hearings today on the Enbridge oil spill in Michigan. Michigan Radio's Steve Carmody reports that one top official was conspicuously abset from the hearings. Cynthia Quarterman recused herself from the oil spill hearings, because she used to work for Enbridge Energy Partners.
