Content:
torical information. The following site and regional data or information should be obtained: ` 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, and principal storm tracks), general airflow patterns, temperature and humidity characteristics, precipitation, and relationships between synoptic and mesoscale (e.g., land-sea [lake] breeze regimes, atmospheric processes and local [site] meteorological conditions) (from the environmental report [ER]) ` a description of regional air quality, including non-attainment or maintenance areas ` a description (including seasonal and annual frequencies) of the severe weather phenomena (e.g., tornadoes, hurricanes, thunderstorms, droughts) and adverse air quality conditions (e.g., SOx, NOx, particulates, salt) affecting the site and vicinity (from the ER) ` monthly and annual air temperature and dewpoint temperature summaries, including averages, measured extremes, and diurnal range (from the ER) ` monthly cumulative frequency distributions of wet-bulb temperature based on long-term data from representative NWS stations (except for plants with once-through cooling) (from the general literature) ` monthly and annual summaries of precipitation, including averages and measured extremes, number of hours with precipitation, hourly rainfall-rate distribution, and monthly precipitation wind roses with precipitation rate classes (from the ER) ` monthly and annual summaries, including natural variability, of occurrences of heavy fog (visibility less than .4 km [.25 mi]), and appropriate summaries of other parameters to support the description of impacts resulting from the operation of a closed cycle heat dissipation system (from the ER) (a) Exceptions to the 8-km (5-mi) site vicinity radius may be required when the land-use descriptions (ESRP 2.2.1) suggest that this is appropriate.
