ed in standard design certification applications.6 II. ACCEPTANCE CRITERIA The information regarding the local meteorological and topographic descriptions of the site area applicable both before plant construction and during plant operation for a CP, OL, COL, or early site permit licensing action should be adequately documented such that meteorological impacts 7 on plant design and operation as well as the impact of the plant on local meteorological conditions can be reliably predicted. The information should be fully documented and substantiated as to its representativeness ofto ensure that it represents conditions at and near the 8 site. For a standard design certification licensing action, local meteorological parameters should be presented in the site parameter envelope specified for the proposed plant design. The 9 information is acceptable if it meets the requirements of the following regulations: 1. 10 CFR Part 50, Appendix A, General Design Criterion 2 (GDC 2), "Design Bases for Protection Against Natural Phenomena," with respect to information on the most severe local weather phenomena that have historically been reported for the site and the surrounding area and that are reflected in the design bases for structures, systems, and components important to safety. 2. 10 CFR Part 100, 100.10(c) with respect to the consideration that has been given to the 10 local meteorological and air quality characteristics of the site and other physical characteristics of the site that can influence the local meteorology. Specific criteria necessary to meet the requirements of GDC 2 and 10 CFR Part 100 are as follows: 1. Local summaries of meteorological data based on onsite measurements in accordance with Regulatory Guide 1.23 and National Weather Service station summaries or other standard installation summaries from appropriate nearby locations should be presented as specified in Regulatory Guide 1.70, Section 2.3.2. 2. A complete topographical description of the site and
