(a) The systems of records entitled “Investigative Files of the Office of Inspector General,” “Hotline Complaint Files of the Office of Inspector General,” “Name Indices System of the Office of Inspector General,” and “AutoInvestigation of the Office of Inspector General” consist, in part, of investigatory material compiled by the OIG for law enforcement purposes. Therefore, to the extent that information in these systems falls within the coverage of exemption (k)(2) of the Privacy Act, 5 U.S.C. 552a(k)(2), these systems of records are exempt from the requirements of the following subsections of the Privacy Act, for the reasons stated in paragraphs (a) (1) through (4) of this section.

(1) From subsection (c)(3), because release of an accounting of disclosures to an individual who is the subject of an investigation could reveal the nature and scope of the investigation and could result in the altering or destruction of evidence, improper influencing of witnesses, and other evasive actions that could impede or compromise the investigation.

(2) From subsection (d)(1), because release of investigative records to an individual who is the subject of an investigation could interfere with pending or prospective law enforcement proceedings, constitute an unwarranted invasion of the personal privacy of third parties, reveal the identity of confidential sources, or reveal sensitive investigative techniques and procedures.

(3) From subsection (d)(2), because amendment or correction of investigative records could interfere with pending or prospective law enforcement proceedings, or could impose an impossible administrative and investigative burden by requiring the OIG to continuously retrograde its investigations attempting to resolve questions of accuracy, relevance, timeliness and completeness.

(4) From subsection (e)(1), because it is often impossible to determine relevance or necessity of information in the early stages of an investigation. The value of such information is a question of judgment and timing; what appears relevant and necessary when collected may ultimately be evaluated and viewed as irrelevant and unnecessary to an investigation. In addition, the OIG may obtain information concerning the violation of laws other than those within the scope of its jurisdiction. In the interest of effective law enforcement, the OIG should retain this information because it may aid in establishing patterns of unlawful activity and provide leads for other law enforcement agencies. Further, in obtaining evidence during an investigation, information may be provided to the OIG which relates to matters incidental to the main purpose of the investigation but which may be pertinent to the investigative jurisdiction of another agency. Such information cannot readily be identified.

(b) The systems of records entitled “Investigative Files of the Office of Inspector General,” “Hotline Complaint Files of the Office of Inspector General,” “Name Indices System of the Office of Inspector General,” and “Autoinvestigation of the Office of Inspector General” consist in part of investigatory material compiled by the OIG for the purpose of determining suitability, eligibility, or qualifications for Federal civilian employment or Federal contracts, the release of which would reveal the identity of a source who furnished information to the Government under an express promise that the identity of the source would be held in confidence. Therefore, to the extent that information in these systems fall within the coverage of exemption (k)(5) of the Privacy Act, 5 U.S.C. 552a(k)(5), these systems of records are exempt from the requirements of subsection (d)(1), because release would reveal the identity of a source who furnished information to the Government under an express promise of confidentiality. Revealing the identity of a confidential source could impede future cooperation by sources, and could result in harassment or harm to such sources.
