Officials with Canadian oil transport corporation Enbridge on Thursday denied reports that the company's twin, underwater, 64-year-old oil and natural gas pipelines in the Straits of Mackinac are losing their protective coating.
A work plan filed by Enbridge with the U.S. Environmental Protection Agency last September, now available on the company's website, references areas of "holidays," the oil and gas industry term for open areas on pipelines where anticorrosion protective coating has fallen off or is missing on the underwater portions of Line 5.
