Mr. James S. Grant Vice President - Energy Supply Edison Plaza 300 Madison Avenue Toledo, OH 43652 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 installed in your facility. This line is part of what has been designated the Off Premise Extension (OPX) network, an automatic ringing system that is designed to facilitate immediate notifications to the NRC of significant incidents and to provide continous and uninte rupted communication of operational information between your f acility, the NPC Operations Center in Bethesda, Mary and, and the Regional Office during the course of such ancidents.
We hare been testing the OPX network on a daily basis for the past several weeks, and plan to continue on this schedule until confidence in the relir5ility of the network has been established and all problems have been eliminated. After that we will continue the tests but at a reduced frequency. A copy of the test procedure is provided as an enclosure to this letter for your information.
The OPX network is not to be used for routine communications with the NRC.
It shall be used only for those events requiring immediate notifi-cation as defined in 10 CFR 20.403(a), and in IE Bulletin Series Nos.
79-CS, -06, and -08, which require notification within one hour of the time a reactor is not in a controlled or expected condition of operation.
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 designated the Selective Signaling System (SS-4) network, a dial-up system - not automatic ringing, which is intended to be used during an incident to provide continuous and uninterupted communication between your facility, the RRC Operations Center, and the Regional Office regarding radiological and environmental matters.
You will be contacted soon regarding the installation of this second line.
