U.S. Demands More Test Data From BP After Seep Found

U.S. government officials ordered BP Plc to submit plans for reopening its sealed Gulf of Mexico well and resuming efforts to capture oil after tests found a suspected leak seeping from the seabed.

In a letter addressed to Bob Dudley, BP managing director, National Incident Commander Thad Allen said tests had detected a “seep a distance from the well and undetermined anomalies at the well head.” The letter was posted on the website of the joint information center for the spill.
