On July 9, 2008, a Notice of Violation was issued to Ahern & Associates, Inc. This action is based on a Severity Level III violation of 10 CFR 30.34(i) involving the licensee's failure to maintain a minimum of two independent physical controls that formed tangible barriers to secure a portable gauge from unauthorized removal during a period when the portable gauge was not under the control and constant surveillance of the licensee. Specifically, a portable gauge was left unattended inside an unlocked storage area with only one physical control (a locked cabinet container) that formed a tangible barrier to secure the portable gauge.
