Vice President, Supply P. O. Box 1475 Baltimore, Maryland 21203 Gentlemen:
In accordance with our plans as described in our May 22, 1979 letter to you, the first of two direct and dedicated telephone lines was recently in-stalled in your facility.
Thi: line is part of what has been designated the Off ?remise Extension (0PX) network, an automatic ringing system that is designed to facilitate immediate notification; to the NRC of significant incidents, and to provide continuous and unir.tarcupted communication of oper-ational information between your facility, the NRC Operations Center in Bethesda, Maryland, and the Regional Office during the course of such inci-dents.
We.; ave been testing the OPX network on a dail, basis for the past several weeks, and plan to continue on this schedele until confidence in the reli-ability of the network has been establisheu and all problems nave been elim-inated.
After that we will continue the tests but at a reduced frequency.
A copy of the test procedure is provided as an enciasure to this letter for your information.
The OPX network is not to be useo for routine communications wid the NRC.
It shall be used only for those events requiring immediate nat'fication as defined in 10 CFR 20.403(a), and in IE Bulletin Series Nos. 79-05, -06, and
-08, which require notification within one hour of the time a reactor is not in a controlled or expected condition of cperation.
In addition, the network shall be used where it is apparent that immediate NRC attention is necessary.
This may include some, but certainly not all, prompt notifications now required.
We are now arranging for the installation of the second direct and dedi-cated line into your facility.
This line will be part of what has been desig-nated the Selective Signaling System (55-4) network, a dial-up system - not automatic ringing, which is intended to be used during an incident to provide continuous and uninterrupted communication between your facility, the NRC Operations Center, and the Regional Office regarcing radiological and environ-mental matters.
You will be contacted soon regarding tne installation of this second line.
