cc:

1.

The types of ~elays mentioned in IE Bulletin 76-02 (GE type llFA$ HG.A, HKA., EMA} are installed in various system1:; at Surry.

Review of the failure history of these relays has revealed that no.:failures of the kind mentioned in the Bulletin have occm:red in the nearly four yem:s of station operation.

Presently, uo.action with rega?:d t.o *Bull.E;tt:tn. 76-02 ia requi:i::ed.

If failures of the type m..'alnt:toued do occur in the future~ we would reevaluate the Bulletin at that time.

2.

The type of relay mentioned in IE Bulletin 76-03 (GE type 12 STD 15B5A) :ts not installed at Surry; therefore no furth~r action is required or planned.
