Enbridge, the company that spilled at least 800,000 gallons of tar sands crude into the Kalamazoo River system last year, has announced that it is suspending efforts to scrape the remaining submerged oil from the river bottom.
UPI reports that the company said it made a “seasonal decision” to stop cleanup for the rest of the year.
The EPA recovered about 18,000 barrels of oil from the surface. Officials said it was unclear how the remaining oil would affect the environment because there is no spill with which to compare the Enbridge leak.
For more than a year, crews have worked to get oil removed from the bottom of the waterways. Heavy crude, unlike conventional crude, sinks and mixes in with the sediment.
According to Enbridge crews have recovered most of the oil.
An approximately thirty mile long stretch of the Kalamazoo River has been off limits to the public since July 2010 because of the oil contamination.
