154.30—General.
Requests for personnel security investigations shall be limited to those required to accomplish the Defense mission. Such requests shall be submitted only by the authorities designated in § 154.31. These authorities shall be held responsible for determining if persons under their jurisdiction require a personnel security investigation. Proper planning must be effected to ensure that investigative requests are submitted sufficiently in advance to allow completion of the investigation before the time it is needed to grant the required clearance or otherwise make the necessary personnel security determination.
