Sec.  211.5   Priorities.

   There are hereby established four levels of restoration priority. Within
   each level, subpriorities may be established by the Executive Agent, with
   the concurrence of the National Security Council, for both government and
   nongovernment services. The subpriorities categories currently in use, which
   have been established by the Executive Agent will remain in effect until
   modified.  Compatibility of subcategories applicable to government and
   nongovernment  users is essential to achieve the objective of a single
   restoration priority system.

   (a)  Priority  1. Priority 1 shall be the highest level of restoration
   priority, and shall be afforded only to Federal and Foreign Government
   private line services, and to Industrial/Commercial services which are
   designated  for  prearranged  voluntary participation with the Federal
   Government in a national emergency. Circuit requirements in this level of
   priority shall be limited to those esential to national survival if nuclear
   attack occurs for:

   (1) Obtaining or disseminating critical intelligence concerning the attack,
   or immediately necessary to maintain the internal security of the United
   States;

   (2) Conducting diplomatic negotiations critical to the arresting or limiting
   of hostilities;

   (3) Executing military command and control functions essential to defense
   and retaliation;

   (4) Giving warning to the U.S. population;

   (5) Maintaining federal Government functions essential to national survival
   under nuclear attack conditions.

   (b) Priority 2. Priority 2 shall be the second highest level of restoration
   priority, and shall be afforded only to Federal and Foreign Government
   private line services, and to Industrial/Commercial services which are
   designated  for  prearranged  voluntary participation with the Federal
   Government in a national emergency. Circuit requirements in this level shall
   be limited to those essential, at a time when nuclear attack threatens, to
   maintain an optimum defense posture and to give civil alert to the U.S.
   population.  These are circuit requirements whose unavailability would
   present serious dangers:

   (1) Reducing significantly the preparedness of U.S. defense and retalitory
   forces;

   (2) Affecting adversely the ability of the United States to conduct critical
   preattack diplomatic negotiations to reduce or limit the threat of war;

   (3) Interfering with the effectual direction of the U.S. population in the
   interest of civil defense and survival;

   (4) Weakening U.S. capability to accomplish critical national internal
   security functions;

   (5) Inhibiting the provision of essential Federal Government functions
   necessary to meet a preattack situation.

   (c) Priority 3. Priority 3 shall be the third highest level of restoration
   priority  and  shall  be afforded to government, quais-government, and
   Industrial/Commercial  private  line services: Provided, however, That
   Priority 3 will be afforded circuits serving Industrial/Commercial, State,
   county, municipal, and quasi-state and local government agencies only where,
   during an emergency, at least one station in the circuit (or in connected
   circuits if switched service is involved) will be manned continually, or
   where such circuits are automated and will be under constant surveillance
   from a remote location. Circuit requirements in this level shall be limited
   to those necessary for U.S. military defense and diplomacy, for law and
   order, and for national health and safety in a national emergency involving
   heightened possibility of hostilities. These are curcuit requirements needed
   to:

   (1)  Insure performance of critical logistic functions, public utility
   services, and administrative-military support functions;

   (2) Inform key diplomatic posts of the situation and of U.S. intentions;

   (3) Secure and disseminate urgent intelligence;

   (4) Distribute essential food and other supplies critical to health;

   (5) Provide for critical damage control functions;

   (6) Provide for hospitalization;

   (7) Continue critical Government functions;

   (8) Provide transportation for the foregoing activities.

   (d) Priority 4. Priority shall be the fourth highest restoration priority
   and   shall   be   afforded   to   government,  quasi-government,  and
   Industrial/Commercial  private  line services: Provided, however, That
   Priority 4 will be afforded circuits serving Industrial/Commercial, State,
   county, municipal, and quasi-state and local government agencies only where,
   during an emergency, at least one station in the circuit (or in connected
   circuits if switched service is involved) will be manned continually, or
   where such circuits are automated and will be under constant surveillance
   from a remote location. Circuit requirements in this level shall be limited
   to  those  necessary for the maintenance of the public welfare and the
   national  economy  in  a  situation short of nuclear attack, or during
   reconstitution after attack. These include circuit requirements needed to
   continue  the  more  important financial, economic, health, and safety
   activities of the Nation.
