The U.S. Environmental Protection Agency has denied Enbridge Inc.'s request for a 10-month extension of its deadline for dredging sections of the Kalamazoo River, polluted by an 800,000-gallon-plus oil pipeline leak in 2010.
The pipeline runs from Sarnia, Ontario, to Griffith, Ind.
The EPA tells Enbridge in a letter that if Enbridge has acted earlier, "It would not require an extension now."
The deadline to finish the work remains Dec. 31.
Enbridge has said that opposition from authorities in Kalamazoo County's Comstock Township to creating a dredge pad slowed the work.
But the EPA said the Calgary, Alberta-based company should have had a backup plan.
