The Individual is a contractor employee at a DOE facility and has possessed a security clearance on various occasions since 1978. Exhibit (Ex.) 8 at 2. In December 2011, the Individual reported to the Local Security Office (LSO) that his wages were being garnished for back federal taxes. Ex. 13 at 1. Consequently, the LSO conducted a personnel security interview (PSI) with the Individual in January 2012. Ex. 15. Because the PSI and further investigation indicated that the Individual had not filed state and federal tax returns for several years and had a number of delinquent financial accounts, the LSO informed the Individual in a March 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 his security clearance was suspended.
