REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of meteorology Secondary - None I. AREAS OF REVIEW Chapter 2 of the SRP discusses the site characteristics that could affect the safe design and siting of the plant. The staff reviews information presented by the applicant for a construction permit (CP), operating license (OL), design certification (DC), early site permit (ESP), or combined license (COL) concerning averages and extremes of climatic conditions and regional meteorological phenomena that could affect the safe design and siting of the plant. This SRP section applies to reviews performed for each of these types of applications. The review covers the following specific areas: 1. A description of the general climate of the region with respect to types of air masses, synoptic features (high- and low-pressure systems and frontal systems), general airflow patterns (wind direction and speed), temperature and humidity, precipitation (rain, snow, sleet, and freezing rain), potential influences from regional topography, and relationships between synoptic-scale atmospheric processes and local (site) meteorological conditions. 2.3.1-2 Revision 3 - March 2007 2. Annual (and seasonal, if available) frequencies of severe weather phenomena, including hurricanes, tornadoes and waterspouts, thunderstorms, severe wind events, lightning, hail (including probable maximum size), and high air pollution potential. 3. Annual frequency of occurrence, amount, and time duration of freezing rain (ice storms) and dust (sand) storms where applicable. 4. Identification of National Climatic Data Center’s (NCDC) state climatic division(s) for the site. 5. The site’s air quality, including the site’s Air Quality Control Region (AQCR) and its attainment designation with respect to state and national ambient air quality standards. 6. Meteorological conditions identified as (1) site characteristics for ESP applications, (2) design and operating bases for CP, OL,
