NEW ORLEANS (AP) — The Coast Guard says a contractor is cleaning up about 11,500 gallons of oil that overflowed from a tank being filled in south Louisiana.

Lt. j.g. Lisa Siebert says much of the oil ended on the ground rather than a nearby bayou. The Environmental Protection Agency took over the investigation and cleanup supervision.

Siebert says Bayou Teche remains closed. Investigators don't know how much oil got into the water.

She says PSC Industrial Outsourcing reported the spill about 8 p.m. Monday and is paying for the cleanup. State police say a shelter-in-place advisory for nearby residents was lifted about 8 a.m. Tuesday. Siebert says the spill apparently happened because an alarm failed to signal that the tank was too full as it was being filled Monday.
