Enbridge says cost of cleaning up Kalamazoo River oil spill near $1-billion

Last week's dredging order by the U.S. Environmental Protection Agency will push Enbridge's cleanup costs for the July 2010 spill close to $1 billion, the company said Wednesday. Enbridge Energy Partners LP said in a filing with the Securities and Exchange Commission that the EPA order will cost the company $175 million and "financial statement recognition for this incident will cause increased volatility in the Partnership's results of operations and cash flows."
