On July 28, 2016, the NRC issued a Notice of Violation and Proposed Imposition of a Civil Penalty in the amount of $7,000 to Tetra Tech EC, Inc. (Tetra Tech), for a Severity Level III violation. The violation involved a deliberate failure to obtain soil sample surveys in accordance with 10 CFR 20.1501(a), by employees of Tetra Tech at U.S. Navy’s Hunter’s Point Naval Shipyard (HPNS) site in San Francisco, California. Specifically, on several occasions between November 18, 2011, and June 4, 2012, when obtaining soil samples to ascertain the amount of residual radioactivity in specific locations within Parcel C at HPNS, Tetra Tech employees deliberately obtained soil samples from other areas that were suspected to be less contaminated and represented that the samples had been obtained from within the specified locations.
