SUBJECT:

Calvert Cliffs Nuc! car Power Plant Unit Nos.1 & 2: Docket Nos. 50-317 & 50-318 Emercency Response Data System The attached revision to the Emergency Response Data System (ERDS) Data Point Library for the Calvert Cliffs Nuclear Power Plant is provided pursuant to 10 CFR Part 50, Appendix E, Section VI.3.a.

This revision deletes plant computer point X2433, Wind Speed at Reactor Site and X2367, Wind Direction at Reactor Site. Both of these data points were supplied signals from the plant's back-up meteorological tower. Instruments on this tower have become obsoletc.. They are no longer being maintained. Meteorological data from the primary meteorological tower is not resident in the plant computer. Pursuant to 10 CFR Part 50, Appendix E, Section VI.1, no retrofitting will be done to connect this data to the computer. Meteorological data will be available via the Emergency Notification System telephone.

Should you have any questions regarding this matter, please contact our ERDS administrative contact, Mr. Thomas E. Forgette, at (410) 260-4996.

Very truly yours, l
