    (2) Such repairs will be performed on power circuits with a phase-
to-phase nominal voltage no greater than 15,000 volts;
    (3) Such repairs on circuits with a phase-to-phase nominal voltage 
of 5,000 volts or more will be performed only with the use of live line 
tools; and,
    (4) Weather conditions will not interfere with such repairs or 
expose those persons assigned to such work to an imminent danger; and,
    (b) The operator has designated a person qualified under the 
provisions of Sec.  77.104 as the person responsible for carrying out 
such repairs and such person, in order to ensure protection for himself 
and other qualified persons assigned to perform such repairs from the 
hazards of such repair, has prepared and filed with the operator:
    (1) A general description of the nature and location of the damage 
or defect to be repaired;
    (2) The general plan to be followed in making such repairs;
    (3) A statement that a briefing of all qualified persons assigned to

their individual assignments, and the dangers inherent in such 
assignments;
    (4) A list of the proper protective equipment and clothing that will 
be provided; and
    (5) Such other information as the person designated by the operator
