O. Foster letter to H. R. Denton, September 25, 1984
Dear Mr. Denton:
I have enclosed pages 7, 8 and 17 from the above referenced transmittal's attachment 3, " Evaluation of Drift Deposition Rates at the Yogtle Electric Generating Plant." During copying, these pages were inadvertently left out of some copies. Also pages 9 through 12 and 15 were intentionally left blank and not included in the attachment.
If you have any questions please contact us.
Yours truly,

7 This peak would occur at 0.9 miles NE of the cooling towers, which is 0.5 miles beyond the site boundary (Appendix 1).
(c) The peak deposition in the E wind sector of VEGP would be:
Wind frequency in the E wind sector = 8.3%
16.2 lb/ac/yr 12%
=
x 8.3%
11.2 lb/ac/yr x
=
This peak would occur at 0.9 miles E of the cooling towers, which is about 0.3 miles beyond the site boundary ( Appendix 1).
In summary, the off site peak deposition at VEGP, which follows Beaver Valley Unit 1 and 2's deposition pattern with the peak deposition at 0.9 miles from the cooling towers, would be approximately 14.7 lb/ac/yr at 1.0 miles SE of the cooling towers, immediately beyond the site boundary.
(3) Similar aproaches can be taken to calculate the other cases and Table 1 summarizes the offsite peak deposition based on the 4 cases described above.
It can be noted from the table that the most conservative prediction for offsite peak deposition at VEGP would be provided by Case 3, having a deposition rate of about 14.7 lb/ac/yr at 1.0 mile SE of the cooling towers.
However, even with this number the offsite peak deposition concentrations are expected to be below the guideline levels for vegetation damage provided by NUREG-0555 and Reg. Guide 4.11.
