TOP   SECRET The   investigative   basis   for   a   Top   Secret clearance   is   the   completion   of   a   favorable SBI,  BI,  or  PR. If,   however,   the   latest investigation  is  older  than  5  years,  a  PR  is required  for  a  person  to  retain  the  clearance. This   PR   must   be   submitted   within   30   days following  granting  of  the  clearance. SECRET/CONFIDENTIAL The   investigative   basis   for   a   Secret   or Confidential   clearance   is   a   favorable ENTNAC   for   first-term   military   enlistees. The   ENTNAC   remains   valid   throughout   the person’s   enlistment,   providing   no   break   in service  greater  than  12  months  occurs. PERSONNEL   RELIABILITY   PROGRAM The investigative requirements for the PRP are  based  on  the  sensitivity  of  the  position. The  program  does  not  require  a  PR;  however, the   individual’s   specific   clearance   may. Positions  in  the  PRP  are  designated  as  either critical  or  controlled. Critical The  minimum  investigative  requirement for  initial  assignment  is  a  valid  BI  completed within  the  past  5  years. This   requirement may  be  satisfied  by  a  valid  favorable  PR  or SBI  completed  within  the  past  5  years.  When the BI, SBI, or latest PR is older than 5 years, a  new  BI  must  be  requested. Controlled The  minimum  investigative  requirement for   initial   assignment   is   a   valid   favorable NAC  completed  within  the  past  5  years.  This requirement   may   be   satisfied   by   a   valid favorable   ENTNAC,   NACI,   BI,   SBI,   or   PR completed  within  the  past  5  years.  When  no investigation has been conducted to satisfy the requirements   for   initial   assignment,   the command  must  request  a  new  NAC. When  an  individual  is  transferred  from one  PRP  assignment  to  another,  the  record  of prior    investigation will   be   accepted   in rescreening   the   individual   at   the   new assignment. DEPARTMENT   OF   THE   NAVY CENTRAL   ADJUDICATION   FACILITY The   Department   of   the   Navy   Central Adjudication   Facility   (DON   CAF)   was established  to  provide  central  evaluation  of individuals  receiving  security  clearances.  This facility  is  the  sole  authority  to  grant,  deny,  or revoke  security  clearances  for  all  Department of  the  Navy  (DON)  personnel.  The  DIS  and the   Office   of   Personnel   Management   (OPM) forward   all   completed   PSIs   to   DON   CAF. The   facility   then   determines   eligibility   for security  clearances  or  assignment  to  sensitive duties. Upon   making   a   favorable   security clearance/eligibility   determination,   DON   CAF will  notify  the  command  by  message,  letter,  or Manpower   Management   System   (MMS),   as appropriate. REQUESTS  FOR  DON MILITARY   PERSONNEL All  requests  for  extensions  of  interim clearances,  security  clearance  revalidations, notification  of  administrative  downgrading  or withdrawal   of   clearances,   and   reports   of derogatory  information  are  submitted  to  DON CAF   via   the   Personnel   Security   Action Request. REVALIDATION   UPON TRANSFER/ACCESS   TO   SPECIAL ACCESS   PROGRAMS When  an  individual  who  has  a  security clearance  transfers  to  a  new  command  into  a duty   assignment   requiring   access   to   special access   program   information,   the   gaining command  revalidates  the  security  clearance and   submits   a   Personnel   Security   Action Request  for  clearance  at  the  level  needed  by the  person  to  perform  those  duties. 8-3
