## Description

On April 6, 2023, the NRC issued a notice of violation to Soil and Materials Engineers, Inc. (licensee) for a Severity Level III violation for which there were two examples. Both examples involved the licensee’s failure to maintain control or constant surveillance of licensed material that is not in storage as required by Title 10 of the Code of Federal Regulations (10 CFR) 20.1802 and failure to use a minimum of two independent physical controls that form tangible barriers to secure portable gauges from unauthorized removal, whenever portable gauges are not under the control and constant surveillance of the licensee as required by 10 CFR 30.34(i). Specifically on September 15, 2022, the licensee left a Troxler Model 3430 gauge unattended in the locked cab of a truck at a jobsite and on October 28, 2022, at a different jobsite, the licensee left a Troxler Model 4640B gauge unattended in an unlocked vehicle with the engine running.
