Coast Guard responding to report of oil sheen in DuSable Harbor

Coast Guard pollution responders on scene believe the sheen was caused by diesel originating from a 30-foot pleasure craft moored in the harbor.
Sorbent boom and sorbent pads have been deployed to contain and recover the product.
The Coast Guard received notification of the discharge around 12:45 p.m.
The DuSable Harbor harbormaster, Chicago Fire Department and Police Department Marine Unit are also on scene and have secured the source of the discharge.
