infor- mation on high air pollution potential for verification. Extreme winds and the specific vertical velocity distribution are checked against References 9 and 10. -Gust factors are checked against Reference 9. The design basis tornado parameters are checked for agreement with Regulatory Guide 1.76 (Ref. 8) and tornado data are verified using the procedures and data in WASH-1300 (Ref. 14). The reviewer provides the findings on meteorological parameters to the Structural Engineering Branch and other branches as necessary for review of the adequacy of the design of structures, systems and components important to safety. 2.3.1-3 Rev. 2 - July 1981 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and that his evaluation supports concluding statements of the following type to be included in the staff's safety evaluation report: The staff has reviewed available information relative to the regional meteorological conditions of importance to the safe design and siting of this plant. The staff concludes that the identification and con- sideration of the meteorological characteristics at the site and in the surrounding area are acceptable and meet the requirements of 10 CFR Part 100, §100.10(c)(2) with respect to determining the acceptability of the site. This conclusion is based on the presenta- tion and substantiation of the meteorological information in accord- ance with acceptable standard practice as promulgated by the National Oceanic and Atmospheric Administration and in industry standards identified in the references hereto, and includes the ultimate heat sink meteorological data as stated in Regulatory Position 1.b of Regulatory Guide 1.27 (Ref. 11).
