| ENS 41101 | 7 October 2004 15:29:00 | Maine Yankee | NRC Region 1 | CE | The licensee provided the following information via facsimile: (The) Maine Emergency Management Agency (was notified) of an unscheduled release that occurred during the 24 hour period ending at midnight on Thursday, 10/07/04. Maine Yankee identified a minor release of 3.18 E-6 Curies of liquid from the site. This release exceeded the value projected for this period and is therefore classified as unscheduled. The total liquid release resulted in a minor exposure value of 2.21 E-5 millirem. The cause of the release resulted from groundwater intrusion of the outfall piping during soil remediation and failure of the clay barrier that was installed. (The) release occurred from 9/30/04 until 10/6/04. The outfall piping is being removed and the area backfilled to eliminate liquid releases via this pathway.
