- 1.3 Implementation of the RERP is required whenever any of the Initi-ating Events of Tables 4.1-1 through 4.1-4 of the RERP occurs.
Refer to ATTACR3ENT 10. 1.4 ATTACHMENT 1 is a check list for use by the CR Director ar.d/or the Emergency Coordinator. This check list is a brief summary of actions and is to be used for guidance purposes only. 1.5 During non-working hours, PSC personnel required to man the re-sponse centers (ATTACR4ENT 12) are notified by telephone. It is the responsibility of the individual response center Alternate Director to insure these notifications are made. Refer to the RERP PHONE LIST for instructions and personnel names and numbers.

\J This procedure should be performed by a person familiar with the instrument-ation used to make a local determination of the stack concentration Dosimeter will be worn when performing this procedure . Exposure time will be kept to a minimum.
- 1. Proceed to the survey area at the exhaust stack on level 10, Turbine Building.
- 2. Insert instrument probe in shielded box at the exhaust stack and note reading (mR/hr) .
- 3. Leave area immediately. Report the instrument used and reading (mR/hr) to the Control Room via the Gai-tronics.
