BP reported on Tuesday an oil sheen was observed after severe thunderstorms in northwest Indiana, in an area of Lake Michigan adjacent to one of the Whiting refinery’s process sewer lines.
A containment boom had been deployed as a precautionary measure before the sheen was observed, and the sheen remains within the containment area, the company said.
