(AP) — Enbridge says it has begun installing steel supports on an oil pipeline in Michigan’s Straits of Mackinac, where erosion has created a gap between the line and the lake bottom. The company said Tuesday it had received a permit from the U.S. Army Corps of Engineers to install 54 supports along the Line 5 pipe in the waterway connecting Lakes Huron and Michigan. The work is expected to be finished later this week.

DETROIT (AP) — An auto engineer has pleaded not guilty in an alleged scheme to fool regulators about the amount of engine pollution emitted from more than 100,000 Fiat Chrysler diesel vehicles. Emanuele Palma entered the plea Tuesday in a Detroit federal court.
