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.
