Authorities say there are no signs of shoreline or wildlife being affected by the discharge of fuel oil from a tanker on the Mississippi River.
The Coast Guard said the discharge from a ballast pipe on the tanker Overseas Beryl was reported shortly after 10 p.m. Monday and it was plugged around 4 a.m. Tuesday.
Cleanup has begun at the site downriver from New Orleans. The amount of fuel oil spilled remained unclear at midmorning.
Plaquemines Parish's homeland security director says drinking water intakes are being monitored but there currently is no effect on the safety or supply for the parish drinking water system. The Coast Guard lists Overseas Shipholding Group Inc. as the responsible party.
