On September 13, 2006, a Notice of Violation was issued for a Severity Level III problem involving a transportation event in which a shipment of low specific activity liquid radioactive waste from San Onofre Unit 1 leaked from its transport container in Utah. The violations involved failures to (1) ensure by examination or appropriate tests that the top discharge valve of the tanker was properly closed and sealed; (2) load the tanker to the required fill density; and (3) maintain, fill, and close the tanker so that, under conditions normally incident to transportation, there would be no identifiable release of materials to the environment.
