continuously  revises  them,  as  necessary.  Naval directives convey policies, procedures, and infor- mation  through  the  Navy  Directives  Issuance System. Some directives pertain to every member of  the  Navy,  while  others  pertain  only  to  a particular command or to a certain geographical area.  Still  others  address  a  particular  mission, idea,  or  goal. INSTRUCTIONS,  NOTICES,  AND CHANGE   TRANSMITTALS Three  types  of  naval  directives  are  used  in  the Department  of  the  Navy:  instructions,  notices, and change transmittals. Instructions An  instruction  is  a  Navy  directive  having continuing  reference  value  or  requiring  continu- ing  action. An  instruction  must  be  issued  when  one  or more  of  the  following  elements  apply. l l l l l l l l l Regulates   or   is   essential   to   effective administration Establishes  policy Delegates   authority   or   assigns   respon- sibility Establishes  an  organizational  structure Assigns  a  mission,  function,  or  task Initiates  or  governs  a  course  of  action  or conduct Establishes a reporting requirement Establishes   a   procedure,   technique, standard  guide,  or  method  of  performing a  duty,  function,  or  operation Changes,  supersedes,  or  cancels  another instruction Notices A notice is a Navy directive issued for a brief duration. It normally remains in effect less than 6  months,  but  is  not  permitted  to  remain  in 3-7 effect longer than 1 year. A notice serves one or more  of  the  following  purposes: l  Requests  comment,  approval,  or  infor- mation . Directs the routine execution of established operations,   such   as   matters   pertaining   to   in- dividual  personnel  actions  or  special  shipments of  material o  Makes  informative  announcements,  such as education or promotion opportunities, recrea- tional   activities,   work   improvement   plans, suggestions   for   morale   building,   changes   in office  locations,  or  telephone  extensions Change Transmittals A  change  transmittal  is  the  medium  used to   transmit   changes   to   an   instruction   or, under   extenuating   circumstances,   a   notice. Each   transmittal   describes   the   nature   of   the changes   issued   and   gives   directions   for   in- corporating  the  changes. DRAFTING  DIRECTIVES When directives are issued by a higher echelon, local commands can issue a directive amplifying the   information   for   application   at   the   local command  level.  For  example,  on  14  December 1983, the Secretary of the Navy issued an instruc- tion   designated   SECNAVINST   1730.7.   This instruction  deals  with  the  Responsibilities  for Religious  Ministries  in  the  Navy.  The  Chief  of Naval   Operations   then   issued   an   instruction, OPNAVINST  1730.1A,  dated  5  November  1984, which amplified SECNAVINST 1730.7 and paved the  way  for  implementation  of  the  parent directive   throughout   OPNAV.   In   turn,   sub- ordinate  commands,  to  which  the  parent  direc- tive  applies,  should  draft  their  own  instruction based on guidance from their chain of command, thereby  implementing  SECNAVINST  1730.7  at the  local  command  level. The  RPC  or  RP1  may  be  tasked  by  the command  chaplain  to  draft  directives  pertain- ing  to  the  CRP  that  reflect  directives  from higher  authority.  When  so  assigned,  the  RPC or  RP1  should  read  carefully  the  governing directive before drafting the command directive. This  will  ensure  that  the  amplifying  informa- tion  is  clearly  defined  for  implementing  the governing  directive.
