Greenaction for Health and Environmental Justice petitioned the U.S. Nuclear Regulatory Commission (NRC) to revoke Tetra Tech’s license to handle radioactive material, alleging Tetra Tech’s contract with the U.S. Navy to clean up the Hunters Point Naval Shipyard Superfund site was “marked by intentional fraud, greed and disregard for” public health and safety. The petitioners allege Tetra Tech employees and its subcontractors engaged in at least six types of fraud: (1) fake sampling, in which potentially thousands of soil samples were reported to have been taken at one location when they were actually taken from another; (2) discarding samples and analytical results that were radiologically too “hot”; (3) altering scanning data to make them appear radiologically acceptable; (4) conducting false building surveys in which certain scan results were fabricated and falsified; (5) improperly remediating radioactive material; and (6) allowing potentially contaminated soil to be shipped offsite for commercial purposes.
