<br />,r' :i.o;.. <br /> <br />A W A response to Question 15. <br /> <br />This is an excellent observation. The south to north orientation of the design storm in the <br />NWSSSS would indicate that the moisture inflow wind would be from the southeast to east. <br />This moisture inflow wind is consistent with extreme rainfall storm scenarios. A more complete <br />discussion can be found in Section 8, page 107. The paragraph on page 108 provides a detailed <br />discussion on the characteristic that is physically not consistent (not physically possible), i.e. the <br />application of a k- factor that is greater than 1.00, The paragraph on page 100 should have <br />emphasized this physical inconsistency instead of the discussion related to moisture inflow <br />winds. <br /> <br />16. Page 104. What is Figure XX? <br /> <br />A W A response to Questionl6. <br /> <br />The reference to the figure that provided storm curves along with the envelopment curve was <br />labeled Figure XX in the draft version before final figure numbers were determined. Figure 10.2 <br />on page 124 is the figure that is referred to in this paragraph. <br /> <br />17. Page 107. Several references are noted in paragraph 2 but not listed in the bibliography. <br />Could we get copies of those references? <br /> <br />A W A response to Questionl7. <br /> <br />It appears that the references are Miller, 1984; Board of Consultants, 1987; NRC, 1987; and <br />FERC, 1988. These should have definitely been included in the References, The references are <br />given below: <br /> <br />Miller, J.F., E.M.Hansen, and D.D.
