l   Supporting   and   other   pertinent documents,   including   those   containing concurrence,   nonconcurrence,   approval,   and significant   comment. FILING   DIRECTIVES Instructions   normally   are   filed   according to  (1)  SSIC,  (2)  consecutive  number,  and  (3) issuing   authority. Checklists   of   directives i s s u e d    by Washington   headquarters organizations  are  organized  in  this  manner.  If local  conditions  require,  however,  directives may  be  filed  primarily  by  issuing  authority  or by   a   combination   of   SSIC   and   issuing authority. Alphabetic  prefixes  (C  and  S, indicating  security  classification)  to  the  subject designation are disregarded in determining the numerical   filing   sequence. Because  of  their  brief  duration,  notices ordinarily  need  not  be  filed  in  the  master  file. If  they  need  to  be  interfiled  temporarily  with instructions,  the  notices  should  be  tabbed  so that  each  may  be  easily  and  promptly removed   as   soon   as   its   cancellation   date   is reached. Copies  may  be  filed  in  separate suspense  binders  when  necessary. Cross-reference  sheets  for  instructions permanently   or   temporarily   removed   from your  office  are  interfiled  with  instructions. Locator   sheets   are   inserted   in   normal sequence,  in  place  of  the  instructions  they reference.   A   subject   cross-reference   sheet   is placed  in  front  of  those  instructions  that  carry the  same  SSIC. A   second   copy   of   the cross-reference  sheet  should  be  placed  in  a suspense   file   for   instructions   temporarily loaned  out.  An  instruction  should  usually  be returned  within  5  days. When   copies   of   directives   are   needed   to complete  a  record  or  to  support  or  further document  a  specific  action,  they  may  be  filed in  the  activity’s  general  subject  files,  pertinent case  files  (such  as  contract  case  files),  or  other appropriate   correspondence   files. ENTERING  CHANGES Proper  notations,  such  as  Ch-1  for  change 1, are entered in the upper right margin of the first  page  of  each  directive  changed.  For publication-type   instructions,   notations   are entered  on  the  record-of-changes  sheet  to indicate  changes  received  and  incorporated. REQUISITIONING    DIRECTIVES Required  additional  or  replacement  copies of   directives,   excluding   notices,   are requisitioned   from   the   stocking   point   shown on   each   directive.   Washington   headquarters organizations normally stock    directives, excluding   notices,   at   the   Naval   Publications and   Forms   Center,   5801   Tabor   Avenue, Philadelphia,   PA 19120.   If   available, Departmental Directives Requisition, N A V S U P    F o rm 1205, is u s e d    f o r requisitioning   copies   of   directives   stocked   at that   location.   The   supply   office   should   have a  supply  of  these  forms. DISPOSITION   OF   DIRECTIVES Each   activity   maintains   the   directives   it receives  only  during  the  period  of  their effectiveness.   Cancelled   directives,   regardless of   classification,   are   destroyed   by   recipients without  notification  to  the  originating  office. An  activity  maintains  its  official  directives case  files  for  the  same  period  it  maintains  its official   correspondence   files.   It   disposes   of them  in  the  same  manner. PREPARATION   OF   DIRECTIVES The  Directives  Issuance  System  Manual, SECNAVINST  5215.1,  contains  complete directions  for  the  preparation  of  instructions and  notices.  Figures  6-1  through  6-6  present the  standard  format  for  directives  and  cross- reference  sheets. 6-4
