The Individual is a contractor employee at a DOE facility. The Local Security Office (LSO) received information that the Individual had not filed a state income tax return for the year 2007. Exhibit (Ex.) 3 at 1. Consequently, LSO conducted a personnel security interview (PSI) with the Individual in October 2011. Ex. 7. Because the 2011 PSI failed to resolve the security concerns raised by the Individual’s failure to file tax returns, the LSO informed the Individual, in a February 2012 notification letter (Notification Letter), that derogatory information existed which raised security concerns under 10 C.F.R. § 710.8 (l) (Criterion L) and that her security clearance was suspended. Ex. 1. The Notification Letter also informed the Individual that she was entitled to a hearing before a Hearing Officer in order to resolve the security concerns.
