(i) Disclosure to the individual named in the record pursuant to 5 U.S.C. 552a(c)(3), (c)(4), or (d)(1) through (4) could seriously impede or compromise the investigation by alerting the target(s), subjecting a potential witness or witnesses to intimidation or improper influence, and leading to destruction of evidence. Disclosure could enable suspects to take action to prevent detection of criminal activities, conceal evidence, or escape prosecution.

(ii) Application of 5 U.S.C. 552a(e)(1) is impractical because the relevance of specific information might be established only after considerable analysis and as the investigation progresses. Effective law enforcement requires the OIG to keep information that may not be relevant to a specific OIG investigation, but which may provide leads for appropriate law enforcement and to establish patterns of activity that might relate to the jurisdiction of the OIG and/or other agencies.

(iii) Application of 5 U.S.C. 552a(e)(2) would be counterproductive to the performance of a criminal investigation because it would alert the individual to the existence of an investigation. In any investigation, it is necessary to obtain evidence from a variety of sources other than the subject of the investigation in order to verify the evidence necessary for successful litigation or prosecution.

(iv) Application of 5 U.S.C. 552a(e)(3) could discourage the free flow of information in a criminal law enforcement inquiry.

(v) The requirements of 5 U.S.C. 552a(e)(4)(G) and (H) and (f) would be counterproductive to the performance of a criminal investigation. To notify an individual at the individual's request of the existence of records in an investigative file pertaining to such individual, or to grant access to an investigative file could interfere with investigative and enforcement proceedings, deprive co-defendants of a right to a fair trial or other impartial adjudication, constitute an unwarranted invasion of personal privacy of others, disclose the identity or confidential sources, reveal confidential information supplied by these sources and disclose investigative techniques and procedures. Nevertheless, Ex-Im Bank OIG has published notice of its notification, access, and contest procedures because access may be appropriate in some cases.

(vi) Although the OIG endeavors to maintain accurate records, application of 5 U.S.C. 552a(e)(5) is impractical because maintaining only those records that are accurate, relevant, timely, and complete and that assure fairness in determination is contrary to established investigative techniques. Information that may initially appear inaccurate, irrelevant, untimely, or incomplete may, when collated and analyzed with other available information, become more pertinent as an investigation progresses.

(vii) Application of 5 U.S.C. 552a(e)(8) could prematurely reveal an ongoing criminal investigation to the subject of the investigation.

(viii) The provisions of subsection (g) do not apply to this system if an exemption otherwise applies.
